Abstract
OBJECTIVES COVID-19 is associated with significant morbidity and mortality. This study aims to synthesize evidence to assess the cost-effectiveness of remdesivir (RDV) for the treatment of hospitalized patients with COVID-19 in England and Wales. METHODS A probabilistic cost-effectiveness analysis was conducted informed by 2 large trials and uses a partitioned survival approach to assess short- and long-term clinical consequences and costs associated with COVID-19 in a hypothetical cohort of hospitalized patients requiring supplemental oxygen at the start of treatment. Given that it is uncertain whether RDV reduces death, 2 analyses are presented, assuming RDV either reduces death or does not. Published sources were used for long-term clinical, quality of life, and cost parameters. RESULTS Under the assumption that RDV reduces death, the incremental cost-effectiveness ratio for RDV is estimated at £11 881 per quality-adjusted life-year gained compared with standard of care (SoC) (probabilistic incremental cost-effectiveness ratio £12 400). The probability for RDV to be cost-effective is 74% at a willingness-to-pay threshold of £20 000 per quality-adjusted life-year gained. RDV was no longer cost-effective when the hazard ratio for overall survival compared with SoC was >0·915. CONCLUSIONS Results from this study suggest that using RDV for the treatment of hospitalized patients with COVID-19 is likely to represent a cost-effective use of National Health Service resources at current willingness-to-pay threshold in England and Wales, only if it prevents death. Results needs to be interpreted caution as vaccination was introduced and the SoC and evidence available have also evolved considerably since the analysis is conducted.

Abstract
UNLABELLED Circulating endothelial progenitor cells (EPCs) contribute to vascular repair and their monitoring could have prognostic clinical value. Exercise is often prescribed for the management of cardiometabolic diseases, however, it is not fully understood how it regulates EPCs. OBJECTIVES to systematically examine the acute and chronic effects of different exercise modalities on circulating EPCs in patients with cardiovascular and metabolic disease. METHODS Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed. RESULTS six electronic databases and reference lists of eligible studies were searched to April 2021. Thirty-six trials met the inclusion criteria including 1731 participants. Acute trials: in chronic heart failure (CHF), EPC mobilisation was acutely increased after high intensity interval or moderate intensity continuous exercise training, while findings were inconclusive after a cardiopulmonary cycling exercise test. Maximal exercise tests acutely increased EPCs in ischaemic or revascularized coronary artery disease (CAD) patients. In peripheral arterial disease (PAD), EPC levels increased up to 24 h post-exercise. In patients with compromised metabolic health, EPC mobilisation was blunted after a single exercise session. Chronic trials: in CHF and acute coronary syndrome, moderate intensity continuous protocols, with or without resistance exercise or calisthenics, increased EPCs irrespective of EPC identification phenotype. Findings were equivocal in CAD regardless of exercise mode, while in severe PAD disease EPCs increased. High intensity interval training increased EPCs in hypertensive metabolic syndrome and heart failure reduced ejection fraction. CONCLUSION the clinical condition and exercise modality influence the degree of EPC mobilisation and magnitude of EPC increases in the long term.

Abstract
The extent to which sleep is causally related to mental health is unclear. One way to test the causal link is to evaluate the extent to which interventions that improve sleep quality also improve mental health. We conducted a meta-analysis of randomised controlled trials that reported the effects of an intervention that improved sleep on composite mental health, as well as on seven specific mental health difficulties. 65 trials comprising 72 interventions and N = 8608 participants were included. Improving sleep led to a significant medium-sized effect on composite mental health (g+ = -0.53), depression (g+ = -0.63), anxiety (g+ = -0.51), and rumination (g+ = -0.49), as well as significant small-to-medium sized effects on stress (g+ = -0.42), and finally small significant effects on positive psychosis symptoms (g+ = -0.26). We also found a dose response relationship, in that greater improvements in sleep quality led to greater improvements in mental health. Our findings suggest that sleep is causally related to the experience of mental health difficulties. Future research might consider how interventions that improve sleep could be incorporated into mental health services, as well as the mechanisms of action that explain how sleep exerts an effect on mental health.

Abstract
ABSTRACT
Background
Chronic kidney disease–associated pruritus (CKD-aP) is a common and burdensome condition for end-stage kidney disease (ESKD) patients, especially those receiving haemodialysis. High-quality evidence of the relationship between CKD-aP and health-related quality of life (HRQoL) can therefore inform clinicians and policymakers about treatment choice and reimbursement decisions.
Methods
A systematic literature review and narrative synthesis stratified by study design and HRQoL instrument was conducted to evaluate in adult ESKD patients receiving in-centre haemodialysis the relationship between CKD-aP and HRQoL assessed using multi dimensional generic or condition-specific preference- or non-preference-based measures. MEDLINE, Embase, Web of Science, BIOSIS Citation Index, Cochrane Library and PsycINFO from inception to March 2020 were searched, with two reviewers extracting data independently.
Results
Searches identified 2684 unique records, of which 20 papers relating to 18 unique studies [5 randomised controlled trials (RCTs) and 13 observational studies] were included. HRQoL was assessed using four generic and eight disease-specific measures. The impact of CKD-aP was assessed by comparison of means, linear regression and correlation. Observational studies employing comprehensively adjusted multivariable linear regression largely found associations between CKD-aP severities and HRQoL. Analyses suggest this relationship is partially mediated by the sleep disturbance caused by CKD-aP. RCTs showing improvements in CKD-aP severity were associated with clinically meaningful improvements in HRQoL. Compared with generic measures, disease-specific HRQoL instruments reported greater changes with reduced CKD-aP. Heterogeneity in study design and reporting precluded meta-analysis.
Conclusions
CKD-aP severity was found to be associated with a worsening of HRQoL in the majority of observational and RCT studies. Parallel improvements in CKD-aP and HRQoL with interventions may support their use (PROSPERO registration 175035).

Abstract
BACKGROUND Fragility fractures are fractures that result from mechanical forces that would not ordinarily result in fracture. OBJECTIVES The objectives were to evaluate the clinical effectiveness, safety and cost-effectiveness of non-bisphosphonates {denosumab [Prolia®; Amgen Inc., Thousand Oaks, CA, USA], raloxifene [Evista®; Daiichi Sankyo Company, Ltd, Tokyo, Japan], romosozumab [Evenity®; Union Chimique Belge (UCB) S.A. (Brussels, Belgium) and Amgen Inc.] and teriparatide [Forsteo®; Eli Lilly and Company, Indianapolis, IN, USA]}, compared with each other, bisphosphonates or no treatment, for the prevention of fragility fracture. DATA SOURCES For the clinical effectiveness review, nine electronic databases (including MEDLINE, EMBASE and the World Health Organization International Clinical Trials Registry Platform) were searched up to July 2018. REVIEW METHODS A systematic review and network meta-analysis of fracture and femoral neck bone mineral density were conducted. A review of published economic analyses was undertaken and a model previously used to evaluate bisphosphonates was adapted. Discrete event simulation was used to estimate lifetime costs and quality-adjusted life-years for a simulated cohort of patients with heterogeneous characteristics. This was done for each non-bisphosphonate treatment, a strategy of no treatment, and the five bisphosphonate treatments previously evaluated. The model was populated with effectiveness evidence from the systematic review and network meta-analysis. All other parameters were estimated from published sources. An NHS and Personal Social Services perspective was taken, and costs and benefits were discounted at 3.5% per annum. Fracture risk was estimated from patient characteristics using the QFracture® (QFracture-2012 open source revision 38, Clinrisk Ltd, Leeds, UK) and FRAX® (web version 3.9, University of Sheffield, Sheffield, UK) tools. The relationship between fracture risk and incremental net monetary benefit was estimated using non-parametric regression. A probabilistic sensitivity analysis and scenario analyses were used to assess uncertainty. RESULTS Fifty-two randomised controlled trials of non-bisphosphonates were included in the clinical effectiveness systematic review and an additional 51 randomised controlled trials of bisphosphonates were included in the network meta-analysis. All treatments had beneficial effects compared with placebo for vertebral, non-vertebral and hip fractures, with hazard ratios varying from 0.23 to 0.94, depending on treatment and fracture type. The effects on vertebral fractures and the percentage change in bone mineral density were statistically significant for all treatments. The rate of serious adverse events varied across trials (0-33%), with most between-group differences not being statistically significant for comparisons with placebo/no active treatment, non-bisphosphonates or bisphosphonates. The incremental cost-effectiveness ratios were > £20,000 per quality-adjusted life-year for all non-bisphosphonate interventions compared with no treatment across the range of QFracture and FRAX scores expected in the population eligible for fracture risk assessment. The incremental cost-effectiveness ratio for denosumab may fall below £30,000 per quality-adjusted life-year at very high levels of risk or for high-risk patients with specific characteristics. Raloxifene was dominated by no treatment (resulted in fewer quality-adjusted life-years) in most risk categories. LIMITATIONS The incremental cost-effectiveness ratios are uncertain for very high-risk patients. CONCLUSIONS Non-bisphosphonates are effective in preventing fragility fractures, but the incremental cost-effectiveness ratios are generally greater than the commonly applied threshold of £20,000-30,000 per quality-adjusted life-year.

Abstract
This was a rapid review of systematic reviews (SRs) on problematic polypharmacy (PP) in the UK. The commissioner-defined topics were burden of PP, interventions to reduce PP, implementation activities to increase uptake of interventions, and efficient handover between primary and secondary care to reduce PP. Databases including Medline were searched to June 2019, SR quality was assessed using AMSTAR-2 (A MeaSurement Tool to Assess systematic Reviews) and a narrative synthesis was undertaken. Except for burden of PP (SRs had to include UK studies), there were no restrictions on country, location of care or outcomes. Nine SRs were included. On burden, three SRs (including six UK studies) found a high prevalence of polypharmacy in long term care. PP was associated with mortality, although unclear if causal, with no information on costs or health consequences. On interventions, six reviews (27 UK studies) found that interventions can reduce PP, but no effects on health outcomes. On handover between primary and secondary care, one review (two UK studies) found medicine reconciliation activities to reduce medication discrepancies at care transitions reduce PP, although the evidence is low quality. No SRs on implementation activities to increase uptake of interventions were found. SR quality was variable, with some concerns regarding meta-analysis methods. Evidence of the extent of PP in the UK, and what interventions to address it are effective in the UK, is limited. Future UK research is needed on the prevalence and consequences of PP, the effectiveness and cost-effectiveness of interventions to reduce PP, and barriers and activities to ensure uptake.

Abstract
OBJECTIVES To determine the clinical effectiveness of denosumab (DEN), raloxifene (RLX), romosozumab (ROMO) and teriparatide (TPTD), within their licensed (or anticipated licensed) indications, for the treatment of osteoporosis. METHODS A systematic review was conducted. Nine electronic databases and trial registries were searched up to the end of July 2018. Studies were eligible for inclusion if they were randomised controlled trials (RCT) in a population at risk of osteoporotic fracture, comparing these four non-bisphosphonates DEN, RLX, ROMO, or TPTD with each other, a non-active treatment, or the bisphosphonates alendronate (ALN), risedronate (RIS), ibandronate (IBN) and zoledronic acid (ZOL). Quality of included studies was assessed using the Cochrane Risk of Bias tool. Network meta-analyses (NMA) were used to determine the relative effectiveness of treatments. RESULTS The systematic review identified 7898 citations. Forty-six RCTs of non-bisphosphonates met the inclusion criteria for the review and provided data for analyses. Additionally 49 RCTs of bisphosphonates were used in the NMAs. Forty-six RCTs were included in the NMA of vertebral fracture data, 23 RCTs for hip fractures and 73 RCTs in the NMA of femoral neck bone mineral density (FN BMD). For vertebral fractures, all four non-bisphosphonates showed statistically significant benefit relative to placebo: TPTD HR 0.23 (95% credible internal (CrI) 0.16, 0.32); ROMO followed by ALN 0.25 (95% CrI 0.15, 0.43); DEN HR 0.30 (95% CrI 0.21, 0.43); RLX HR 0.61 (95% CrI 0.44, 0.80). The four non-bisphosphonates interventions studied also showed statistically significant benefit relative to placebo for FN BMD, and for hip fractures TPTD, ROMO followed by ALN, and DEN showed statistically significant benefit relative to placebo. CONCLUSIONS The four non-bisphosphonate interventions studied were all statistically significantly clinically effective for reducing vertebral fractures when compared to placebo, and were beneficial for change in FN BMD compared to placebo. All reduced hip fractures, and this was statistically significant for TPTD, ROMO followed by ALN, and DEN.

Abstract
OBJECTIVES There are many rapid review methods; however, there is little pragmatic guidance on which methods to select. This study aimed to reach consensus among international rapid review experts outlining areas to consider when selecting approaches for rapid reviews. STUDY DESIGN AND SETTING A two-round modified online Delphi survey was conducted between May and July 2018. Participants were asked to rank the importance of a predefined list of 19 items. A consensus definition of at least 70% agreement for each item was decided a priori. RESULTS Thirty experts from ten countries participated in round 1 and 24 in round 2. During round 1, consensus was reached on all items. One additional item on quality assessment was suggested by respondents and comments suggested wording changes to improve clarity and understanding of the tool. Respondents in the second round indicated a high level of importance and all 20 items achieved consensus. These items addressed interaction with commissioners, scoping and searching the evidence-base, data extraction and synthesis methods, and reporting of rapid review methods. CONCLUSION International consensus was reached to produce the SelecTing Approaches for Rapid Reviews (STARR) decision tool for planning rapid reviews and will lead to improved shared understanding between review teams and review commissioners.

Abstract
As part of its Single Technology Appraisal process, the National Institute for Health and Care Excellence (NICE) invited the manufacturer (Pfizer) of tofacitinib (TOF; Xeljanz®) to submit evidence of the drug's clinical and cost-effectiveness in the treatment of rheumatoid arthritis (RA) after the failure of conventional disease-modifying antirheumatic drugs (cDMARDs). The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). The ERG produced a detailed review of the evidence for the clinical and cost-effectiveness of the technology, based upon the company's submission to NICE. The clinical effectiveness evidence in the company's submission for TOF is based predominantly on four randomised controlled trials (RCTs) comparing the efficacy of TOF against placebo. Three RCTs investigated TOF in combination with methotrexate (MTX), and one RCT investigated TOF monotherapy. All four RCTs compared TOF with placebo plus cDMARDs, one RCT also included adalimumab as a comparator. The study population in the four RCTs comprised patients who were MTX inadequate responders or cDMARD inadequate responders (cDMARD-IR). The company performed network meta-analyses (NMA) to assess the relative efficacy of TOF compared with biologic DMARDs (bDMARDs) in patients who were cDMARD-IR or bDMARD-IR with moderate-to-severe RA for European League Against Rheumatism (EULAR) response and change in the Health Assessment Questionnaire Disability Index at 6 months. The company's NMA concluded that TOF had comparable efficacy to bDMARDs currently recommended by NICE. The company submitted a de novo model that assessed the cost-effectiveness of TOF versus its comparators in six different populations: (1) cDMARD-IR with severe RA; (2) cDMARD-IR with severe RA for whom MTX is contraindicated or not tolerated; (3) bDMARD-IR; (4) bDMARD-IR for whom rituximab (RTX) is contraindicated or not tolerated; (5) bDMARD-IR for whom MTX is contraindicated or not tolerated; and, (6) cDMARD-IR with moderate RA. According to the company's economic analyses, in cDMARD-IR with severe RA, TOF plus MTX dominates or extendedly dominates most comparators, whilst TOF monotherapy is slightly less effective and less expensive than its comparators, with the cost saved per quality-adjusted life year (QALY) lost always higher than £50,000. In bDMARD-IR with severe RA, RTX plus MTX dominated TOF plus MTX, but in patients for whom RTX was not an option, TOF plus MTX dominated all comparators included in the analysis (four comparators recommended by NICE were not included). In cDMARD-IR with moderate RA, the cost per QALY for TOF in combination with MTX or as monotherapy compared with a sequence of cDMARDs was estimated to be greater than £50,000/QALY. The ERG identified a number of limitations in the company's analyses, including use of a fixed-effects model in the NMA and the use of treatment sequences in the cost-effectiveness model which did not reflect NICE recommendations. These limitations were addressed partly by the company during the clarification round and partly by the ERG. The exploratory analyses undertaken by the ERG resulted in similar conclusions: (1) TOF plus MTX was dominated by RTX plus MTX; (2) TOF in combination with MTX or as monotherapy dominates or extendedly dominates some of its comparators in cDMARD-IR and bDMARD-IR with severe RA for whom RTX plus MTX was not an option; and (3) in cDMARD-IR with moderate RA, the cost per QALY of TOF in combination with MTX or as a monotherapy versus cDMARDs was in excess of £47,000. The NICE Appraisal Committee consequently recommended TOF plus MTX as an option for patients whose disease has responded inadequately to intensive therapy with a combination of cDMARDs only if (1) disease is severe [a Disease Activity Score (DAS28) of more than 5.1] and (2) the company provides TOF with the discount agreed in the Patient Access Scheme (PAS). TOF plus MTX is also recommended as an option for adults whose disease has responded inadequately to, or who cannot have, other DMARDs, including at least one bDMARD, only if (1) disease is severe, (2) they cannot have RTX, and (3) the company provides TOF with the discount agreed in the PAS. For patients who are intolerant of MTX, or where MTX is contraindicated, TOF monotherapy is recommended where TOF plus MTX would be recommended.

Abstract
As part of its single technology appraisal process, the National Institute for Health and Care Excellence (NICE) invited the company that manufactures ponatinib (Inclusig®; Incyte Corporation) to submit evidence for the clinical and cost effectiveness for previously treated chronic myeloid leukaemia (CML) and Philadelphia-chromosome-positive acute lymphoblastic leukaemia (Ph+ ALL). This paper focusses on the three phases of CML: the chronic phase (CP), the accelerated phase (AP) and the blast crisis phase (BP). The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). This article presents the critical review of the company's submission by the ERG and the outcome of the NICE guidance. Clinical evidence for ponatinib was derived from a phase II, industry-sponsored, single-arm, open-label, multicentre, non-comparative study. Despite the limited evidence and potential for biases, this study demonstrated that ponatinib was likely to be an effective treatment (in terms of major cytogenetic response and major haematological response) with an acceptable safety profile for patients with CML. Given the absence of any head-to-head studies comparing ponatinib with other relevant comparators, the company undertook a matching-adjusted indirect comparison (MAIC) of ponatinib with bosutinib. The approach was only used for patients with CP-CML because comprehensive data were not available for the AP- or BP-CML groups to allow the matching technique to be used. Despite the uncertainty about the MAIC approach, ponatinib was considered likely to offer advantages over bosutinib in the third-line setting, particularly for complete cytogenetic response. The company developed two health economic models to assess the cost effectiveness of ponatinib for the treatment of patients in CP-CML or in advanced CML (AP- or BP-CML, which were modelled separately). The company did not adequately explore the uncertainty in the survivor functions. As a result, the ERG believed the uncertainty in the decision problem was underestimated. Exploratory analyses undertaken by the ERG produced the following results for ponatinib. In CP-CML, from £18,246 to £27,667 per quality-adjusted life-year (QALY) gained compared with best supportive care (BSC), from £19,680 to £37,381 per QALY gained compared with bosutinib and from £18,279 per QALY gained to dominated compared with allogeneic stem cell transplant (allo-SCT). In AP-CML, the cost per QALY gained for ponatinib ranged from £7123 to £17,625 compared with BSC, and from dominating to £61,896 per QALY gained compared with allo-SCT. In BP-CML, the cost effectiveness of ponatinib ranged from £5033 per QALY gained to dominated compared with allo-SCT, although it was likely to be at the more favourable end of this range, and dominant in all scenarios compared with BSC. The NICE appraisal committee concluded that ponatinib is a cost-effective use of NHS resources in the considered population, subject to the company providing the agreed discount in the Patient Access Scheme.

Abstract
BACKGROUND Treat to target (TTT) is a broad concept for treating patients with rheumatoid arthritis (RA). It involves setting a treatment target, usually remission or low disease activity (LDA). This is often combined with frequent patient assessment and intensive and rapidly adjusted drug treatment, sometimes based on a formal protocol. OBJECTIVE To investigate the clinical effectiveness and cost-effectiveness of TTT compared with routine care. DATA SOURCES Databases including EMBASE and MEDLINE were searched from 2008 to August 2016. REVIEW METHODS A systematic review of clinical effectiveness was conducted. Studies were grouped according to comparisons made: (1) TTT compared with usual care, (2) different targets and (3) different treatment protocols. Trials were subgrouped by early or established disease populations. Study heterogeneity precluded meta-analyses. Narrative synthesis was undertaken for the first two comparisons, but was not feasible for the third. A systematic review of cost-effectiveness was also undertaken. No model was constructed as a result of the heterogeneity among studies identified in the clinical effectiveness review. Instead, conclusions were drawn on the cost-effectiveness of TTT from papers relating to these studies. RESULTS Sixteen clinical effectiveness studies were included. They differed in terms of treatment target, treatment protocol (where one existed) and patient visit frequency. For several outcomes, mixed results or evidence of no difference between TTT and conventional care was found. In early disease, two studies found that TTT resulted in favourable remission rates, although the findings of one study were not statistically significant. In established disease, two studies showed that TTT may be beneficial in terms of LDA at 6 months, although, again, in one case the finding was not statistically significant. The TICORA (TIght COntrol for RA) trial found evidence of lower remission rates for TTT in a mixed population. Two studies reported cost-effectiveness: in one, TTT dominated usual care; in the other, step-up combination treatments were shown to be cost-effective. In 5 of the 16 studies included the clinical effectiveness review, no cost-effectiveness conclusion could be reached, and in one study no conclusion could be drawn in the case of patients denoted low risk. In the remaining 10 studies, and among patients denoted high risk in one study, cost-effectiveness was inferred. In most cases TTT is likely to be cost-effective, except where biological treatment in early disease is used initially. No conclusions could be drawn for established disease. LIMITATIONS TTT refers not to a single concept, but to a range of broad approaches. Evidence reflects this. Studies exhibit substantial heterogeneity, which hinders evidence synthesis. Many included studies are at risk of bias. FUTURE WORK Future studies comparing TTT with usual care must link to existing evidence. A consistent definition of remission in studies is required. There may be value in studies to establish the importance of different elements of TTT (the setting of a target, the intensive use of drug treatments and protocols pertaining to those drugs and the frequent assessment of patients). CONCLUSION In early RA and studies of mixed early and established RA populations, evidence suggests that TTT improves remission rates. In established disease, TTT may lead to improved rates of LDA. It remains unclear which element(s) of TTT (the target, treatment protocols or increased frequency of patient visits) drive these outcomes. Future trials comparing TTT with usual care and/or different TTT targets should use outcomes comparable with existing literature. Remission, defined in a consistent manner, should be the target of choice of future studies. STUDY REGISTRATION This study is registered as PROSPERO CRD42015017336.

Abstract
As part of its single technology appraisal (STA) process, the UK National Institute for Health and Care Excellence (NICE) invited the manufacturer (Incyte Corporation) of ponatinib (Inclusig®) to submit evidence of its clinical and cost effectiveness for previously treated Philadelphia-chromosome-positive acute lymphoblastic leukaemia (Ph+ ALL) and chronic myeloid leukaemia. This paper focusses on Ph+ ALL. The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent evidence review group (ERG). This article presents the critical review of the company's submission by the ERG and the outcome of the NICE guidance. The clinical-effectiveness evidence in the company's submission was derived from a phase II, single-arm, open-label, non-comparative study. Given the lack of comparative evidence, a naïve indirect comparison was performed against re-induction chemotherapy comparing major cytogenetic response and complete remission. Best supportive care (BSC) was assumed to produce no disease response. Despite the limited evidence and potential for biases, this study demonstrated that ponatinib was likely to be an effective treatment for patients with Ph+ ALL. The company submitted a state transition model that analysed the incremental cost effectiveness of ponatinib versus re-induction therapy and BSC for the treatment of Ph+ ALL in patients whose disease is resistant to dasatinib, who are intolerant to dasatinib and for whom subsequent treatment with imatinib is not clinically appropriate or who have the threonine-315-isoleucine mutation. This population was further subdivided into those who were suitable for allogeneic stem cell transplant (allo-SCT) and those who were not. The company's revised economic evaluation, following the clarification process, estimated incremental cost-effectiveness ratios (ICERs) in those suitable for allo-SCT of £31,123 per quality-adjusted life-year (QALY) gained for ponatinib compared with re-induction chemotherapy and £26,624 per QALY gained compared with BSC. For those for whom allo-SCT was unsuitable, the company-estimated ICER compared with BSC was £33,954 per QALY gained. Following a critique of the model, the ERG undertook exploratory analyses that, when combined, produced a range in ICERs (due to uncertainty of the most appropriate overall survival function) of dominant (being less expensive and providing more QALYs) to £11,727 per QALY gained compared with re-induction chemotherapy and between £7892 and £31,696 per QALY gained compared with BSC for those in whom allo-SCT was suitable. For those in whom allo-SCT was not suitable, the ERG estimated that ponatinib was dominant. During the consultation period, the company agreed a revised patient access scheme (PAS) that reduced the ICER ranges to £7156 to £29,995 per QALY gained versus BSC and to less than £5000 per QALY gained versus re-induction chemotherapy. In people for whom allo-SCT was unsuitable, ponatinib dominated BSC. The NICE appraisal committee concluded that ponatinib is a cost-effective use of UK NHS resources in the considered population, subject to the company providing the agreed discount in the PAS.

Abstract
INTRODUCTION To compare the ability of Body Mass Index (BMI), waist circumference (WC) and waist to height ratio (WHtR) to estimate cardiovascular disease (CVD) risk levels in adolescents. EVIDENCE ACQUISITION A systematic review and meta-analysis was performed after a database search for relevant literature (Cochrane, Centre for Review and Dissemination, PubMed, British Nursing Index, CINAHL, BIOSIS citation index, ChildData, metaRegister). EVIDENCE SYNTHESIS The study included 117 records representing 96 studies with 994,595 participants were included in the systematic review, 14 of which (13 studies, N.=14,610) were eligible for the meta-analysis. The results of the meta-analysis showed that BMI was a strong indicator of systolic blood pressure, diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol and insulin; but not total cholesterol, low-density lipoprotein or glucose. Few studies were eligible for inclusion in the meta-analysis considering WC or WHtR (N.≤2). The narrative synthesis found measures of central adiposity to be consistently valid indicators of the same risk factors as BMI. CONCLUSIONS BMI was an indicator of CVD risk. WC and WHtR were efficacious for indicating the same risk factors BMI performed strongly for, though there was insufficient evidence to judge the relative strength of each measure possibly due to heterogeneity in the methods for measuring and classifying WC.

Abstract
OBJECTIVES To undertake a systematic review and meta-analysis to evaluate the test performance including sensitivity and specificity of rapid immunochromatographic syphilis (ICS) point-of-care (POC) tests at antenatal clinics compared with reference standard tests (non-treponemal (TP) and TP tests) for active syphilis in pregnant women. METHODS Five electronic databases were searched (PubMed, EMBASE, CRD, Cochrane Library and LILACS) to March 2016 for diagnostic accuracy studies of ICS test and standard reference tests for syphilis in pregnant women. Methodological quality was assessed using QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies). A bivariate meta-analysis was undertaken to generate pooled estimates of diagnostic parameters. Results were presented using a coupled forest plot of sensitivity and specificity and a scatter plot. RESULTS The methodological quality of the five included studies with regards to risk of bias and applicability concern judgements was either low or unclear. One study was judged as high risk of bias for patient selection due to exclusion of pregnant women with a previous history of syphilis, and one study was judged at high risk of bias for study flow and timing as not all patients were included in the analysis. Five studies contributed to the meta-analysis, providing a pooled sensitivity and specificity for ICS of 0.85 (95% CrI: 0.73 to 0.92) and 0.98 (95% CrI: 0.95 to 0.99), respectively. CONCLUSIONS This review and meta-analysis observed that rapid ICS POC tests have a high sensitivity and specificity when performed in pregnant women at antenatal clinics. However, the methodological quality of the existing evidence base should be taken into consideration when interpreting these results. PROSPERO REGISTRATION NUMBER CRD42016036335.

Abstract
BACKGROUND Fragility fractures are fractures that result from mechanical forces that would not ordinarily result in fracture. OBJECTIVES To evaluate the clinical effectiveness and safety of bisphosphonates [alendronic acid (Fosamax® and Fosamax® Once Weekly, Merck Sharp & Dohme Ltd), risedronic acid (Actonel® and Actonel Once a Week®, Warner Chilcott UK Ltd), ibandronic acid (Bonviva®, Roche Products Ltd) and zoledronic acid (Aclasta®, Novartis Pharmaceuticals UK Ltd)] for the prevention of fragility fracture and to assess their cost-effectiveness at varying levels of fracture risk. DATA SOURCES For the clinical effectiveness review, six electronic databases and two trial registries were searched: MEDLINE, EMBASE, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Web of Science and BIOSIS Previews, Clinicaltrials.gov and World Health Organization International Clinical Trials Registry Platform. Searches were limited by date from 2008 until September 2014. REVIEW METHODS A systematic review and network meta-analysis (NMA) of effectiveness studies were conducted. A review of published economic analyses was undertaken and a de novo health economic model was constructed. Discrete event simulation was used to estimate lifetime costs and quality-adjusted life-years (QALYs) for each bisphosphonate treatment strategy and a strategy of no treatment for a simulated cohort of patients with heterogeneous characteristics. The model was populated with effectiveness evidence from the systematic review and NMA. All other parameters were estimated from published sources. A NHS and Personal Social Services perspective was taken, and costs and benefits were discounted at 3.5% per annum. Fracture risk was estimated from patient characteristics using the QFracture® (QFracture-2012 open source revision 38, Clinrisk Ltd, Leeds, UK) and FRAX® (web version 3.9, University of Sheffield, Sheffield, UK) tools. The relationship between fracture risk and incremental net benefit (INB) was estimated using non-parametric regression. Probabilistic sensitivity analysis (PSA) and scenario analyses were used to assess uncertainty. RESULTS Forty-six randomised controlled trials (RCTs) were included in the clinical effectiveness systematic review, with 27 RCTs providing data for the fracture NMA and 35 RCTs providing data for the femoral neck bone mineral density (BMD) NMA. All treatments had beneficial effects on fractures versus placebo, with hazard ratios varying from 0.41 to 0.92 depending on treatment and fracture type. The effects on vertebral fractures and percentage change in BMD were statistically significant for all treatments. There was no evidence of a difference in effect on fractures between bisphosphonates. A statistically significant difference in the incidence of influenza-like symptoms was identified from the RCTs for zoledronic acid compared with placebo. Reviews of observational studies suggest that upper gastrointestinal symptoms are frequently reported in the first month of oral bisphosphonate treatment, but pooled analyses of placebo-controlled trials found no statistically significant difference. A strategy of no treatment was estimated to have the maximum INB for patients with a 10-year QFracture risk under 1.5%, whereas oral bisphosphonates provided maximum INB at higher levels of risk. However, the PSA suggested that there is considerable uncertainty regarding whether or not no treatment is the optimal strategy until the QFracture score is around 5.5%. In the model using FRAX, the mean INBs were positive for all oral bisphosphonate treatments across all risk categories. Intravenous bisphosphonates were estimated to have lower INBs than oral bisphosphonates across all levels of fracture risk when estimated using either QFracture or FRAX. LIMITATIONS We assumed that all treatment strategies are viable alternatives across the whole population. CONCLUSIONS Bisphosphonates are effective in preventing fragility fractures. However, the benefit-to-risk ratio in the lowest-risk patients may be debatable given the low absolute QALY gains and the potential for adverse events. We plan to extend the analysis to include non-bisphosphonate therapies. STUDY REGISTRATION This study is registered as PROSPERO CRD42013006883.

Abstract
BACKGROUND Sepsis can lead to multiple organ failure and death. Timely and appropriate treatment can reduce in-hospital mortality and morbidity. OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of three tests [LightCycler SeptiFast Test MGRADE(®) (Roche Diagnostics, Risch-Rotkreuz, Switzerland); SepsiTest(TM) (Molzym Molecular Diagnostics, Bremen, Germany); and the IRIDICA BAC BSI assay (Abbott Diagnostics, Lake Forest, IL, USA)] for the rapid identification of bloodstream bacteria and fungi in patients with suspected sepsis compared with standard practice (blood culture with or without matrix-absorbed laser desorption/ionisation time-of-flight mass spectrometry). DATA SOURCES Thirteen electronic databases (including MEDLINE, EMBASE and The Cochrane Library) were searched from January 2006 to May 2015 and supplemented by hand-searching relevant articles. REVIEW METHODS A systematic review and meta-analysis of effectiveness studies were conducted. A review of published economic analyses was undertaken and a de novo health economic model was constructed. A decision tree was used to estimate the costs and quality-adjusted life-years (QALYs) associated with each test; all other parameters were estimated from published sources. The model was populated with evidence from the systematic review or individual studies, if this was considered more appropriate (base case 1). In a secondary analysis, estimates (based on experience and opinion) from seven clinicians regarding the benefits of earlier test results were sought (base case 2). A NHS and Personal Social Services perspective was taken, and costs and benefits were discounted at 3.5% per annum. Scenario analyses were used to assess uncertainty. RESULTS For the review of diagnostic test accuracy, 62 studies of varying methodological quality were included. A meta-analysis of 54 studies comparing SeptiFast with blood culture found that SeptiFast had an estimated summary specificity of 0.86 [95% credible interval (CrI) 0.84 to 0.89] and sensitivity of 0.65 (95% CrI 0.60 to 0.71). Four studies comparing SepsiTest with blood culture found that SepsiTest had an estimated summary specificity of 0.86 (95% CrI 0.78 to 0.92) and sensitivity of 0.48 (95% CrI 0.21 to 0.74), and four studies comparing IRIDICA with blood culture found that IRIDICA had an estimated summary specificity of 0.84 (95% CrI 0.71 to 0.92) and sensitivity of 0.81 (95% CrI 0.69 to 0.90). Owing to the deficiencies in study quality for all interventions, diagnostic accuracy data should be treated with caution. No randomised clinical trial evidence was identified that indicated that any of the tests significantly improved key patient outcomes, such as mortality or duration in an intensive care unit or hospital. Base case 1 estimated that none of the three tests provided a benefit to patients compared with standard practice and thus all tests were dominated. In contrast, in base case 2 it was estimated that all cost per QALY-gained values were below £20,000; the IRIDICA BAC BSI assay had the highest estimated incremental net benefit, but results from base case 2 should be treated with caution as these are not evidence based. LIMITATIONS Robust data to accurately assess the clinical effectiveness and cost-effectiveness of the interventions are currently unavailable. CONCLUSIONS The clinical effectiveness and cost-effectiveness of the interventions cannot be reliably determined with the current evidence base. Appropriate studies, which allow information from the tests to be implemented in clinical practice, are required. STUDY REGISTRATION This study is registered as PROSPERO CRD42015016724.

Abstract
BACKGROUND Ulcerative colitis (UC) is the most common form of inflammatory bowel disease in the UK. UC can have a considerable impact on patients' quality of life. The burden for the NHS is substantial. OBJECTIVES To evaluate the clinical effectiveness and safety of interventions, to evaluate the incremental cost-effectiveness of all interventions and comparators (including medical and surgical options), to estimate the expected net budget impact of each intervention, and to identify key research priorities. DATA SOURCES Peer-reviewed publications, European Public Assessment Reports and manufacturers' submissions. The following databases were searched from inception to December 2013 for clinical effectiveness searches and from inception to January 2014 for cost-effectiveness searches for published and unpublished research evidence: MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library including the Cochrane Systematic Reviews Database, Cochrane Controlled Trials Register, Database of Abstracts of Reviews of Effects, the Health Technology Assessment database and NHS Economic Evaluation Database; ISI Web of Science, including Science Citation Index, and the Conference Proceedings Citation Index-Science and Bioscience Information Service Previews. The US Food and Drug Administration website and the European Medicines Agency website were also searched, as were research registers, conference proceedings and key journals. REVIEW METHODS A systematic review [including network meta-analysis (NMA)] was conducted to evaluate the clinical effectiveness and safety of named interventions. The health economic analysis included a review of published economic evaluations and the development of a de novo model. RESULTS Ten randomised controlled trials were included in the systematic review. The trials suggest that adult patients receiving infliximab (IFX) [Remicade(®), Merck Sharp & Dohme Ltd (MSD)], adalimumab (ADA) (Humira(®), AbbVie) or golimumab (GOL) (Simponi(®), MSD) were more likely to achieve clinical response and remission than those receiving placebo (PBO). Hospitalisation data were limited, but suggested more favourable outcomes for ADA- and IFX-treated patients. Data on the use of surgical intervention were sparse, with a potential benefit for intervention-treated patients. Data were available from one trial to support the use of IFX in paediatric patients. Safety issues identified included serious infections, malignancies and administration site reactions. Based on the NMA, in the induction phase, all biological treatments were associated with statistically significant beneficial effects relative to PBO, with the greatest effect associated with IFX. For patients in response following induction, all treatments except ADA and GOL 100 mg at 32-52 weeks were associated with beneficial effects when compared with PBO, although these were not significant. The greatest effects at 8-32 and 32-52 weeks were associated with 100 mg of GOL and 5 mg/kg of IFX, respectively. For patients in remission following induction, all treatments except ADA at 8-32 weeks and GOL 50 mg at 32-52 weeks were associated with beneficial effects when compared with PBO, although only the effect of ADA at 32-52 weeks was significant. The greatest effects were associated with GOL (at 8-32 weeks) and ADA (at 32-52 weeks). The economic analysis suggests that colectomy is expected to dominate drug therapies, but for some patients, colectomy may not be considered acceptable. In circumstances in which only drug options are considered, IFX and GOL are expected to be ruled out because of dominance, while the incremental cost-effectiveness ratio for ADA versus conventional treatment is approximately £50,300 per QALY gained. LIMITATIONS The health economic model is subject to several limitations: uncertainty associated with extrapolating trial data over a lifetime horizon, the model does not consider explicit sequential pathways of non-biological treatments, and evidence relating to complications of colectomy was identified through consideration of approaches used within previous models rather than a full systematic review. CONCLUSIONS Adult patients receiving IFX, ADA or GOL were more likely to achieve clinical response and remission than those receiving PBO. Further data are required to conclusively demonstrate the effect of interventions on hospitalisation and surgical outcomes. The economic analysis indicates that colectomy is expected to dominate medical treatments for moderate to severe UC. STUDY REGISTRATION This study is registered as PROSPERO CRD42013006883.

Abstract
Opiate substitution treatment and needle exchanges have reduced blood borne virus (BBV) transmission among people who inject drugs (PWID). Psychosocial interventions could further prevent BBV. A systematic review and meta-analysis examined whether psychosocial interventions (e.g. CBT, skills training) compared to control interventions reduced BBV risk behaviours among PWID. 32 and 24 randomized control trials (2000-May 2015 in MEDLINE, PsycINFO, CINAHL, Cochrane Collaboration and Clinical trials, with an update in MEDLINE to December 2016) were included in the review and meta-analysis respectively. Psychosocial interventions appear to reduce: sharing of needles/syringes compared to education/information (SMD −0.52; 95% CI −1.02 to −0.03; I2 = 10%; p = 0.04) or HIV testing/counselling (SMD −0.24; 95% CI −0.44 to −0.03; I2 = 0%; p = 0.02); sharing of other injecting paraphernalia (SMD −0.24; 95% CI −0.42 to −0.06; I2 = 0%; p < 0.01) and unprotected sex (SMD −0.44; 95% CI −0.86 to −0.01; I2 = 79%; p = 0.04) compared to interventions of a lesser time/intensity, however, moderate to high heterogeneity was reported. Such interventions could be included with other harm reduction approaches to prevent BBV transmission among PWID.

Abstract
CONTEXT Phosphodiesterase type 5 inhibitors (PDE5-Is) are prescribed off-label for the treatment of premature ejaculation (PE). OBJECTIVE To systematically review the evidence from randomised controlled trials (RCTs) for PDE5-Is in the management of PE. EVIDENCE ACQUISITION Medline and other databases were searched through September 2015. Quality of RCTs was assessed. Intravaginal ejaculatory latency time (IELT) data were pooled in a meta-analysis. Heterogeneity was assessed. EVIDENCE SYNTHESIS Fifteen RCTs were included. The majority were of unclear methodological quality. Pooled IELT evidence suggests that PDE5-Is are significantly more effective than placebo (231 participants, p<0.00001), that there is no difference between PDE5-Is and selective serotonin reuptake inhibitors (SSRIs; 405 participants, p=0.50), and that PDE5-Is combined with an SSRI are significantly more effective than SSRIs alone (521 participants, p=0.001); however, high levels of statistical heterogeneity are evident (I2 ≥ 40%). Single-RCT evidence suggests that sildenafil is significantly more effective than the squeeze technique, but both lidocaine gel and tramadol are significantly more effective than sildenafil. Sildenafil combined with behavioural therapy is significantly more effective than behavioural therapy alone. Sexual satisfaction and ejaculatory control appear to be better with PDE5-Is compared with placebo and with PDE5-Is combined with an SSRI compared with an SSRI alone. Adverse events are reported with both PDE5-Is and other agents. CONCLUSIONS PDE5-Is are significantly more effective than placebo and PDE5-Is combined with an SSRI are significantly more effective than SSRIs alone at increasing IELT and improving other effectiveness outcomes; however, heterogeneity is evident across RCTs. The methodological quality of the majority of RCTs is unclear. PATIENT SUMMARY We reviewed phosphodiesterase type 5 inhibitors (PDE5-Is) for treating premature ejaculation. We found evidence to suggest that PDE5-Is are effective compared with placebo and that PDE5-Is combined with an SSRI are more effective than an SSRI alone. Adverse events are reported with PDE5-Is and other agents; however, the quality of the evidence is uncertain. TRIAL REGISTRATION PROSPERO registration number CRD42013005289.

Abstract
BACKGROUND Drug-using offenders with co-occurring mental health problems are common in the criminal justice system. A combination of drug use and mental health problems makes people more likely to be arrested for criminal involvement after release compared to offenders without a mental health problem. Previous research has evaluated interventions aimed broadly at those with a drug problem but rarely with drug use and mental health problems. This systematic review considers the effectiveness of interventions for drug-using offenders with co-occurring mental health problems. METHODS We searched 14 electronic bibliographic databases up to May 2014 and five Internet resources. The review included randomised controlled trials designed to reduce, eliminate, or prevent relapse of drug use and/or criminal activity. Data were reported on drug and crime outcomes, the identification of mental health problems, diagnoses and resource information using the Drummond checklist. The systematic review used standard methodological procedures as prescribed by the Cochrane collaboration. RESULTS Eight trials with 2058 participants met the inclusion criteria. These evaluated: case management (RR, 1.05, 95 % CI 0.90 to 1.22, 235 participants), motivational interviewing and cognitive skills, (MD-7.42, 95 % CI-0.20.12 to 5.28, 162 participants) and interpersonal psychotherapy (RR 0.67, 95 % CI 0.3 to 1.5, 38 participants). None of these trials reported significant reductions in self-report drug misuse or crime. Four trials evaluating differing therapeutic community models showed reductions in re-incarceration (RR 0.28, 95 % CI 0.13 to 0.63, 139 participants) but not re-arrest (RR 1.65, 95 % CI 0.83 to 3.28, 370 participants) or self-report drug use (RR 0.73, 95 % CI 0.53 to 1.01, 370 participants). Mental health problems were identified across the eight trials and 17 different diagnoses were described. Two trials reported some resource information suggesting a cost-beneficial saving when comparing therapeutic communities to a prison alternative. CONCLUSIONS Overall, the studies showed a high degree of variation, warranting a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. Specifically, tailored interventions are required to assess the effectiveness of interventions for drug-using offenders with co-occurring mental health problems.

Abstract
BACKGROUND Ulcerative colitis (UC) is the most common form of inflammatory bowel disease in the UK. Medical management aims to induce and maintain remission and to avoid complications and the necessity for surgical intervention. Colectomy removes the source of inflammation but is associated with morbidity and mortality. Newer anti-tumour necrosis factor (TNF)-α therapies may improve medical outcomes, albeit at an increased cost. OBJECTIVE Our objective was to assess the incremental cost effectiveness of infliximab, adalimumab and golimumab versus conventional therapy and surgery from a National Health Service (NHS) and Personal Social Services (PSS) perspective over a lifetime horizon. METHODS A Markov model was developed with health states defined according to whether the patient is alive or dead, current treatments received, history of colectomy and level of disease control. Transition probabilities were derived from network meta-analyses (NMAs) of trials of anti-TNF-α agents in the moderate-to-severe UC population. Health utilities, colectomy rates, surgical complications and resource use estimates were derived from literature. Unit costs were drawn from standard costing sources and literature and were valued at year 2013/2014 values. RESULTS For patients in whom surgery is an option, colectomy is expected to dominate all medical treatment options. For patients in whom colectomy is not an option, infliximab and golimumab are expected to be ruled out due to dominance, whilst the incremental cost-effectiveness ratio (ICER) for adalimumab versus conventional treatment is expected to be approximately £50,278 per quality-adjusted life-year (QALY) gained. CONCLUSIONS Based on the NMAs, the ICERs for anti-TNF-α therapy versus conventional treatment or surgery are expected to be at best, in excess of £50,000 per QALY gained. The cost effectiveness of withdrawing biologic therapy upon remission and re-treating relapse is unknown.

Abstract
Background Rapid reviews are of increasing importance within health technology assessment due to time and resource constraints. There are many rapid review methods available although there is little guidance as to the most suitable methods. We present three case studies employing differing methods to suit the evidence base for each review and outline some issues to consider when selecting an appropriate method. Methods Three recently completed systematic review short reports produced for the UK National Institute for Health Research were examined. Different approaches to rapid review methods were used in the three reports which were undertaken to inform the commissioning of services within the NHS and to inform future trial design. We describe the methods used, the reasoning behind the choice of methods and explore the strengths and weaknesses of each method. Results Rapid review methods were chosen to meet the needs of the review and each review had distinctly different challenges such as heterogeneity in terms of populations, interventions, comparators and outcome measures (PICO) and/or large numbers of relevant trials. All reviews included at least 10 randomised controlled trials (RCTs), each with numerous included outcomes. For the first case study (sexual health interventions), very diverse studies in terms of PICO were included. P-values and summary information only were presented due to substantial heterogeneity between studies and outcomes measured. For the second case study (premature ejaculation treatments), there were over 100 RCTs but also several existing systematic reviews. Data for meta-analyses were extracted directly from existing systematic reviews with new RCT data added where available. For the final case study (cannabis cessation therapies), studies included a wide range of interventions and considerable variation in study populations and outcomes. A brief summary of the key findings for each study was presented and narrative synthesis used to summarise results for each pair of interventions compared. Conclusions Rapid review methods need to be chosen to meet both the nature of the evidence base of a review and the challenges presented by the included studies. Appropriate methods should be chosen after an assessment of the evidence base.

Abstract
OBJECTIVES To assess the relative efficacy of bisphosphonates (alendronate, risedronate, ibandronate and zoledronic acid) for the treatment of osteoporosis using network meta-analysis (NMA). METHODS A systematic review of the literature was conducted using PRISMA guidelines. A network meta-analysis was used to determine the relative efficacy of treatments on four fracture outcomes (vertebral, non-vertebral, hip and wrist) and percentage change in femoral neck bone mineral density (BMD). Treatment effects were modelled using an exchangeable treatment effects model. Heterogeneity in treatment effects was explored by considering potential treatment effect modifiers using meta-regression. Where appropriate, inconsistency between direct and indirect evidence was assessed using node-splitting. RESULTS 46 randomised controlled trials (RCTs) were identified. Twenty seven RCTs provided fracture data and 35 RCTs provided BMD data for analysis. Zoledronic acid was associated with the greatest treatment effect on vertebral fractures (HR 0.41, 95% CrI: 0.28, 0.56) and percentage change in BMD (3.21, 95%: CrI 2.52, 3.86) compared to placebo. The greatest treatment effect on non-vertebral and wrist fractures was given by risedronate (HR 0.72, 95%: CrI 0.53, 0.89 and HR 0.77, 95%: CrI 0.44, 1.24, respectively). For hip fractures the greatest treatment effect was given by alendronate (HR 0.78, 95% CrI: 0.44, 1.30). CONCLUSIONS All treatments examined were associated with beneficial effects on fractures and femoral neck BMD relative to placebo. For vertebral fractures and percentage change in femoral neck BMD the treatment effects were statistically significant for all treatments. Pairwise comparisons between treatments indicated that no active treatment was statistically significantly more effective than any other active treatment for fracture outcomes. There was some heterogeneity in treatment effects between studies suggesting differential treatment effects according to study characteristics; however, there was no evidence of differential treatment effects with respect to gender and age.

Abstract
BACKGROUND Premature ejaculation (PE) is commonly defined as ejaculation with minimal sexual stimulation before, on or shortly after penetration and before the person wishes it. PE can be either lifelong and present since first sexual experiences (primary), or acquired (secondary), beginning later (Godpodinoff ML. Premature ejaculation: clinical subgroups and etiology. J Sex Marital Ther 1989;15:130-4). Treatments include behavioural and pharmacological interventions. OBJECTIVE To systematically review evidence for clinical effectiveness of behavioural, topical and systemic treatments for PE. DATA SOURCES The following databases were searched from inception to 6 August 2013 for published and unpublished research evidence: MEDLINE; EMBASE; Cumulative Index to Nursing and Allied Health Literature; The Cochrane Library including the Cochrane Systematic Reviews Database, Cochrane Controlled Trials Register, Database of Abstracts of Reviews of Effects and the Health Technology Assessment database; ISI Web of Science, including Science Citation Index, and the Conference Proceedings Citation Index-Science. The US Food and Drug Administration website and the European Medicines Agency (EMA) website were also searched. METHODS Randomised controlled trials (RCTs) in adult men with PE were eligible (or non-RCTs in the absence of RCTs). RCT data were extrapolated from review articles when available. The primary outcome was intravaginal ejaculatory latency time (IELT). Data were meta-analysed when possible. Other outcomes included sexual satisfaction, control over ejaculation, relationship satisfaction, self-esteem, quality of life, treatment acceptability and adverse events (AEs). RESULTS A total of 103 studies (102 RCTs, 65 from reviews) were included. RCTs were available for all interventions except yoga. The following interventions demonstrated significant improvements (p < 0.05) in arithmetic mean difference in IELT compared with placebo: topical anaesthetics - eutectic mixture of local anaesthetics (EMLA(®), AstraZeneca), topical eutectic mixture for PE (Plethora Solutions Ltd) spray; selective serotonin reuptake inhibitors (SSRIs) - citalopram (Cipramil(®), Lundbeck), escitalopram (Cipralex(®), Lundbeck), fluoxetine, paroxetine, sertraline, dapoxetine (Priligy(®), Menarini), 30 mg or 60 mg; serotonin-noradrenaline reuptake inhibitors - duloxetine (Cymbalta(®), Eli Lilly & Co Ltd); tricyclic antidepressants - inhaled clomipramine 4 mg; phosphodiesterase-5 (PDE5) inhibitors - vardenafil (Levitra(®), Bayer), tadalafil (Cialis(®), Eli Lilly & Co Ltd); opioid analgesics - tramadol (Zydol SR(®), Grünenthal). Improvements in sexual satisfaction and other outcomes compared with placebo were evident for SSRIs, PDE5 inhibitors and tramadol. Outcomes for interventions not compared with placebo were as follows: behavioural therapies - improvements over wait list control in IELT and other outcomes, behavioural therapy plus pharmacotherapy better than either therapy alone; alpha blockers - terazosin (Hytrin(®), AMCO) not significantly different to antidepressants in ejaculation control; acupuncture - improvements over sham acupuncture in IELT, conflicting results for comparisons with SSRIs; Chinese medicine - improvements over treatment as usual; delay device - improvements in IELT when added to stop-start technique; yoga - improved IELT over baseline, fluoxetine better than yoga. Treatment-related AEs were evident with most pharmacological interventions. LIMITATIONS Although data extraction from reviews was optimised when more than one review reported data for the same RCT, the reliability of the data extraction within these reviews cannot be guaranteed by this assessment report. CONCLUSIONS Several interventions significantly improved IELT. Many interventions also improved sexual satisfaction and other outcomes. However, assessment of longer-term safety and effectiveness is required to evaluate whether or not initial treatment effects are maintained long term, whether or not dose escalation is required, how soon treatment effects end following treatment cessation and whether or not treatments can be stopped and resumed at a later time. In addition, assessment of the AEs associated with long-term treatment and whether or not different doses have differing AE profiles is required.

Abstract
Eutectic Mixture of Local Anaesthetics (EMLA) is recommended for use off-label as a treatment for premature ejaculation (PE). Other topical anaesthetics are available, some of which have been evaluated against oral treatments. The purpose of this systematic review was to evaluate the evidence from randomised controlled trials (RCTs) for topical anaesthetics in the management of PE. Bibliographic databases including MEDLINE were searched to August 2014. The primary outcome was intra-vaginal ejaculatory latency time (IELT). Methodological quality of RCTs was assessed. IELT and other outcomes were pooled across RCTs in a meta-analysis. Between-trial heterogeneity was assessed. Nine RCTs were included. Seven were of unclear methodological quality. Pooled evidence (two RCTs, 43 participants) suggests that EMLA is significantly more effective than placebo at increasing IELT (P < 0.00001). Individual RCT evidence also suggests that Topical Eutectic-like Mixture for Premature Ejaculation (TEMPE) spray and lidocaine gel are both significantly more effective than placebo (P = 0.003; P < 0.00001); and lidocaine gel is significantly more effective than sildenafil or paroxetine (P = 0.01; P = 0.0001). TEMPE spray is associated with significantly more adverse events than placebo (P = 0.003). More systemic adverse events are reported with tramadol, sildenafil and paroxetine than with lidocaine gel. Diverse methods of assessing sexual satisfaction and ejaculatory control with topical anaesthetics are reported and evidence is conflicting. Topical anaesthetics appear more effective than placebo, paroxetine and sildenafil at increasing IELT in men with PE. However, the methodological quality of the existing RCT evidence base is uncertain.

Abstract
INTRODUCTION Premature ejaculation (PE) is defined by short ejaculatory latency and inability to delay ejaculation causing distress. Management may involve behavioral and/or pharmacological approaches. AIM To systematically review the randomized controlled trial (RCT) evidence for behavioral therapies in the management of PE. METHODS Nine databases including MEDLINE were searched up to August 2014. Included RCTs compared behavioral therapy against waitlist control or another therapy, or behavioral plus drug therapy against drug treatment alone. [Correction added on 10 September 2015, after first online publication: Search period has been amended from August 2013 to August 2014.]. MAIN OUTCOME MEASURE Intravaginal ejaculatory latency time (IELT), sexual satisfaction, ejaculatory control, and anxiety and adverse effects. RESULTS Ten RCTs (521 participants) were included. Overall risk of bias was unclear. All studies assessed physical techniques, including squeeze and stop-start, sensate focus, stimulation device, and pelvic floor rehabilitation. Only one RCT included a psychotherapeutic approach (combined with stop-start and drug treatment). Four trials compared behavioral therapies against waitlist control, of which two (involving squeeze, stop-start, and sensate focus) reported IELT differences of 7-9 minutes, whereas two (web-based sensate focus, stimulation device) reported no difference in ejaculatory latency posttreatment. For other outcomes (sexual satisfaction, desire, and self-confidence), some waitlist comparisons significantly favored behavioral therapy, whereas others were not significant. Three trials favored combined behavioral and drug treatment over drug treatment alone, with small but significant differences in IELT (0.5-1 minute) and significantly better results on other outcomes (sexual satisfaction, ejaculatory control, and anxiety). Direct comparisons of behavioral therapy vs. drug treatment gave mixed results, mostly either favoring drug treatment or showing no significant difference. No adverse effects were reported, though safety data were limited. CONCLUSIONS There is limited evidence that physical behavioral techniques for PE improve IELT and other outcomes over waitlist and that behavioral therapies combined with drug treatments give better outcomes than drug treatments alone. Further RCTs are required to assess psychotherapeutic approaches to PE.

Abstract
BACKGROUND The review represents one in a family of four reviews focusing on a range of different interventions for drug-using offenders. This specific review considers pharmacological interventions aimed at reducing drug use or criminal activity, or both, for illicit drug-using offenders. OBJECTIVES To assess the effectiveness of pharmacological interventions for drug-using offenders in reducing criminal activity or drug use, or both. SEARCH METHODS We searched Fourteen electronic bibliographic databases up to May 2014 and five additional Web resources (between 2004 and November 2011). We contacted experts in the field for further information. SELECTION CRITERIA We included randomised controlled trials assessing the efficacy of any pharmacological intervention a component of which is designed to reduce, eliminate or prevent relapse of drug use or criminal activity, or both, in drug-using offenders. We also report data on the cost and cost-effectiveness of interventions. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as expected by Cochrane. MAIN RESULTS Fourteen trials with 2647 participants met the inclusion criteria. The interventions included in this review report on agonistic pharmacological interventions (buprenorphine, methadone and naltrexone) compared to no intervention, other non-pharmacological treatments (e.g. counselling) and other pharmacological drugs. The methodological trial quality was poorly described, and most studies were rated as 'unclear' by the reviewers. The biggest threats to risk of bias were generated through blinding (performance and detection bias) and incomplete outcome data (attrition bias). Studies could not be combined all together because the comparisons were too different. Only subgroup analysis for type of pharmacological treatment were done. When compared to non-pharmacological, we found low quality evidence that agonist treatments are not effective in reducing drug use or criminal activity, objective results (biological) (two studies, 237 participants (RR 0.72 (95% CI 0.51 to 1.00); subjective (self-report), (three studies, 317 participants (RR 0.61 95% CI 0.31 to 1.18); self-report drug use (three studies, 510 participants (SMD: -0.62 (95% CI -0.85 to -0.39). We found low quality of evidence that antagonist treatment was not effective in reducing drug use (one study, 63 participants (RR 0.69, 95% CI 0.28 to 1.70) but we found moderate quality of evidence that they significantly reduced criminal activity (two studies, 114 participants, (RR 0.40, 95% CI 0.21 to 0.74).Findings on the effects of individual pharmacological interventions on drug use and criminal activity showed mixed results. In the comparison of methadone to buprenorphine, diamorphine and naltrexone, no significant differences were displayed for either treatment for self report dichotomous drug use (two studies, 370 participants (RR 1.04, 95% CI 0.69 to 1.55), continuous measures of drug use (one study, 81 participants, (mean difference (MD) 0.70, 95% CI -5.33 to 6.73); or criminal activity (one study, 116 participants, (RR 1.25, 95% CI 0.83 to 1.88) between methadone and buprenorphine. Similar results were found for comparisons with diamorphine with no significant differences between the drugs for self report dichotomous drug use for arrest (one study, 825 participants, (RR 1.25, 95% CI 1.03 to 1.51) or naltrexone for dichotomous measures of reincarceration (one study, 44 participants, (RR 1.10, 95% CI 0.37 to 3.26), and continuous outcome measure of crime, (MD -0.50, 95% CI -8.04 to 7.04) or self report drug use (MD 4.60, 95% CI -3.54 to 12.74). AUTHORS' CONCLUSIONS When compared to non-pharmacological treatment, agonist treatments did not seem effective in reducing drug use or criminal activity. Antagonist treatments were not effective in reducing drug use but significantly reduced criminal activity. When comparing the drugs to one another we found no significant differences between the drug comparisons (methadone versus buprenorphine, diamorphine and naltrexone) on any of the outcome measures. Caution should be taken when interpreting these findings, as the conclusions are based on a small number of trials, and generalisation of these study findings should be limited mainly to male adult offenders. Additionally, many studies were rated at high risk of bias.

Abstract
BACKGROUND This is an updated version of an original Cochrane review published in Issue 3 2006 (Perry 2006). The review represents one from a family of four reviews focusing on interventions for drug-using offenders. This specific review considers interventions aimed at reducing drug use or criminal activity, or both for drug-using offenders with co-occurring mental illness. OBJECTIVES To assess the effectiveness of interventions for drug-using offenders with co-occurring mental illness in reducing criminal activity or drug use, or both. SEARCH METHODS We searched 14 electronic bibliographic databases up to May 2014 and 5 Internet resources (searched between 2004 and 11 November 2009). We contacted experts in the field for further information. SELECTION CRITERIA We included randomised controlled trials designed to reduce, eliminate, or prevent relapse of drug use and criminal activity, or both in drug-using offenders with co-occurring mental illness. We also reported data on the cost and cost-effectiveness of interventions. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS Eight trials with 2058 participants met the inclusion criteria. The methodological quality of the trials was generally difficult to rate due to a lack of clear reporting. On most 'Risk of bias' items, we rated the majority of studies as unclear. Overall, we could not statistically combine the results due to the heterogenous nature of the different study interventions and comparison groups. A narrative summary of the findings identified that the interventions reported limited success with reducing self report drug use, but did have some impact on re-incarceration rates, but not re-arrest. In the single comparisons, we found moderate-quality evidence that therapeutic communities determine a reduction in re-incarceration but reported less success for outcomes of re-arrest, moderate quality of evidence and self report drug use. Three single studies evaluating case management via a mental health drug court (very low quality of evidence), motivational interviewing and cognitive skills (low and very low quality of evidence) and interpersonal psychotherapy (very low quality of evidence) did not report significant reductions in criminal activity and self report drug use respectively. Quality of evidence for these three types of interventions was low to very low. The trials reported some cost information, but it was not sufficient to be able to evaluate the cost-effectiveness of the interventions. AUTHORS' CONCLUSIONS Two of the five trials showed some promising results for the use of therapeutic communities and aftercare, but only in relation to reducing subsequent re-incarceration. Overall, the studies showed a high degree of variation, warranting a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. More evaluations are required to assess the effectiveness of interventions for drug-using offenders with co-occurring mental health problems.

Abstract
BACKGROUND This is an updated version of a Cochrane review first published in Issue 3, 2006 (Perry 2006). The review represents one in a family of four reviews focusing on the effectiveness of interventions in reducing drug use and criminal activity for offenders. This specific review considers interventions for female drug-using offenders. OBJECTIVES To assess the effectiveness of interventions for female drug-using offenders in reducing criminal activity, or drug use, or both. SEARCH METHODS We searched 14 electronic bibliographic databases up to May 2014 and five additional Website resources (between 2004 and November 2011). We contacted experts in the field for further information. SELECTION CRITERIA We included randomised controlled trials (RCTs) designed to reduce, eliminate or prevent relapse of drug use or criminal activity in female drug-using offenders. We also reported data on the cost and cost-effectiveness of interventions. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS Nine trials with 1792 participants met the inclusion criteria. Trial quality and risks of bias varied across each study. We rated the majority of studies as being at 'unclear' risk of bias due to a lack of descriptive information. We divided the studies into different categories for the purpose of meta-analyses: for any psychosocial treatments in comparison to treatment as usual we found low quality evidence that there were no significant differences in arrest rates, (two studies; 489 participants; risk ratio (RR) 0.82, 95% confidence interval (CI) 0.45 to 1.52) or drug use (one study; 77 participants; RR 0.65, 95% CI 0.20 to 2.12), but we found moderate quality evidence that there was a significant reduction in reincarceration, (three studies; 630 participants; RR 0.46, 95% CI 0.34 to 0.64). Pharmacological intervention using buprenorphine in comparison to a placebo did not significantly reduce self reported drug use (one study; 36 participants; RR 0.58, 95% CI 0.25 to 1.35). No cost or cost-effectiveness evidence was reported in the studies. AUTHORS' CONCLUSIONS Three of the nine trials show a positive trend towards the use of any psychosocial treatment in comparison to treatment as usual showing an overall significant reduction in subsequent reincarceration, but not arrest rates or drug use. Pharmacological interventions in comparison to a placebo did not significantly reduce drug use and did not measure criminal activity. Four different treatment comparisons showed varying results and were not combined due to differences in the intervention and comparison groups. The studies overall showed a high degree of heterogeneity for types of comparisons and outcome measures assessed, which limited the possibility to pool the data. Descriptions of treatment modalities are required to identify the important elements for treatment success in drug-using female offenders. More trials are required to increase the precision of confidence with which we can draw conclusions about the effectiveness of treatments for female drug-using offenders.

Abstract
BACKGROUND Tramadol is a centrally acting analgesic prescribed off-label for the treatment of premature ejaculation (PE). However, tramadol may cause addiction and difficulty in breathing and the beneficial effect of tramadol in PE is yet not supported by a high level of evidence. The purpose of this study was to systematically review the evidence from randomised controlled trials (RCT) for tramadol in the management of PE. METHODS We searched bibliographic databases including MEDLINE to August 2014 for RCTs. The primary outcome was intra-vaginal ejaculatory latency time (IELT). Methodological quality of RCTs was assessed. Between-group differences in IELT and other outcomes were pooled across RCTs in a meta-analysis. Statistical and clinical between-trial heterogeneity was assessed. RESULTS A total of eight RCTs that evaluated tramadol against a comparator were included. The majority of RCTs were of unclear methodological quality due to limited reporting. Pooled evidence (four RCTs, 721 participants), suggests that tramadol is significantly more effective than placebo at increasing IELT over eight to 12 weeks (p = 0.0007). However, a high level of statistical heterogeneity is evident (I-squared = 74%). Single RCT evidence indicates that tramadol is significantly more effective than paroxetine taken on-demand, sildenafil, lidocaine gel, or behavioural therapy on IELT in men with PE. Tramadol is associated with significantly more adverse events including: erectile dysfunction, constipation, nausea, headache, somnolence, dry mouth, dizziness, pruritus, and vomiting, than placebo or behavioural therapy over eight to 12 weeks of treatment. However, addiction problems or breathing difficulties reported by patients for PE is not assessed in the current evidence base. CONCLUSIONS Tramadol appears effective in the treatment of PE. However, these findings should be interpreted with caution given the observed levels of between-trial heterogeneity and the reporting quality of the available evidence. The variability across placebo-controlled trials in terms of the tramadol dose evaluated and the treatment duration does not permit any assessment of a safe and effective minimum daily dose. The long-term effects and side effects, including addiction potential, for men with PE have not been evaluated in the current evidence base. TRIAL REGISTRATION The review is registered on PROSPERO 2013: CRD42013005289 .

Abstract
BACKGROUND This is an updated version of a Cochrane review first published in Issue 3, 2006 (Perry 2006). The review represents one in a family of four reviews focusing on the effectiveness of interventions in reducing drug use and criminal activity for offenders. This specific review considers interventions for female drug-using offenders. OBJECTIVES To assess the effectiveness of interventions for female drug-using offenders in reducing criminal activity or drug use, or both. SEARCH METHODS We searched 14 electronic bibliographic databases (between 2004 and 21st March 2013) and five additional web resources (between 2004 and November 2011). We contacted experts in the field for further information. SELECTION CRITERIA We include randomised controlled trials designed to reduce, eliminate or prevent relapse in female drug-using offenders. We also report data on the cost and cost effectiveness of interventions. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by the Cochrane Collaboration. MAIN RESULTS We identified 76 trials across the four reviews. Following a process of prescreening, we judged that 11 trials met the inclusion criteria of the specified review; four of the 11 trials are awaiting classification in the review. The remaining seven trials cover 1236 participants. The interventions included in this review report on therapeutic communities (TCs), gender-responsive treatment (GRT), use of case management and cognitive skills, and a pharmacological intervention using buprenorphine. Trial quality and risks of bias varied across each study. The majority of studies were rated as being at 'unclear' risk of bias due to a lack of descriptive information. Overall the interventions showed statistically significant reductions in self-reported drug use, (four studies, 734 participants, risk ratio (RR) 0.68; 95% confidence interval (CI) 0.58 to 0.80) and re-incarceration, (four studies, 745 participants, RR 0.55; 95% CI 0.41 to 0.72). We found a statistically non-significant result for re-arrest (three studies, 803 participants, RR 0.80; 95% CI 0.53 to 1.19). Individual treatment results found that TCs and a GRT programme showed a statistically significant reduction in re-incarceration (one study, 509 participants, RR 0.42; 95% CI 0.29 to 0.60) but not for re-arrest, (one study, 314 participants, RR 0.73; 95% CI 0.52 to 1.03) and self-reported drug use (two studies, 825 participants, RR 0.47; 95% CI 0.14 to 1.53). Case management and cognitive skills programmes did not significantly reduce re-arrests, (one study, 183 participants RR 1.12; 95% CI 0.89 to 1.41) or self-reported drug use, (one study, 77 participants, RR 0.65; 95% CI 0.20 to 2.12), but did show a statistically significant reduction in re-incarceration, (three studies, 236 participants, RR 0.63; 95% CI 0.49 to 0.81). Buprenorphine did not significantly reduce self-reported drug use (RR 0.58; 95% CI 0.25 to 1.35), but this result came from a single study with only 36 participants. Due to the small number of studies we were unable to analyse the impact of treatment setting on outcome. No cost and cost effectiveness evidence was reported in the studies. AUTHORS' CONCLUSIONS The seven trials show some positive results for the use of treatments to reduce self-reported drug use and subsequent re-incarceration. However, the studies overall showed a high degree of statistical variation, requiring a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. Descriptions of treatment modalities are required to identify the important elements for treatment success in drug-using female offenders. More trials are required to increase the confidence with which we can draw conclusions about the effectiveness of treatments for female drug-using offenders.

BACKGROUND This is an updated version of an original Cochrane review published in Issue 3 2006 (Perry 2006). The review represents one from a family of four reviews focusing on interventions for drug-using offenders. This specific review considers interventions aimed at reducing drug use or criminal activity, or both for drug-using offenders with co-occurring mental illness. OBJECTIVES To assess the effectiveness of interventions for drug-using offenders with co-occurring mental illness in reducing criminal activity or drug use, or both. SEARCH METHODS We searched 14 electronic bibliographic databases (searched between 2004 and 21 March 2013) and five internet resources (searched between 2004 and 11 November 2009). We contacted experts in the field for further information. SELECTION CRITERIA We included randomised controlled trials designed to reduce, eliminate or prevent relapse in drug-using offenders with co-occurring mental illness. We also reported data on the cost and cost effectiveness of interventions. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS We identified 76 trials across the four reviews. Following a process of pre-screening, we judged eight trials to meet the inclusion criteria for this specific review (three of the five trials are awaiting classification). The five included 1502 participants. The interventions reported on case management via a mental health drugs court, a therapeutic community, and an evaluation of a motivational interviewing technique and cognitive skills in comparison to relaxation training. The methodological quality of the trials was generally difficult to rate due to a lack of clear reporting. On most risk of bias items, we rated the majority of studies as unclear. Overall, the combined interventions did not show a statistically significant reduction in self reported drug use (2 studies, 715 participants; risk ratio (RR) 0.82, 95% confidence interval (CI) 0.44 to 1.55). A statistically significantly reduction was shown for re-incarceration (4 studies, 627 participants; RR 0.40, 95% CI 0.24 to 0.67 and mean difference (MD) 28.72, 95% CI 5.89 to 51.54) but not re-arrest (2 studies, 518 participants; RR 1.00, 95% CI 0.90 to 1.12). A specific subgroup analysis combining studies using therapeutic community interventions showed a statistically significant reduction in re-incarceration (2 studies, 266 participants; RR 0.29, 95% CI 0.16 to 0.54) but not re-arrest (1 study, 428 participants; RR 0.90, 95% CI 0.61 to 1.33). Case management via a mental health court and motivational interviewing with cognitive skills did not show a statistically significant reduction in criminal activity (1 study, 235 participants; RR 1.05, 95% CI 0.90 to 1.22) or self reported drug misuse (1 study, 162 participants; MD -7.42, 95% CI -20.12 to 5.28). Due to the small number of studies, we were unable to analyse the impact of setting on outcome. Some cost information was provided in the trials but not sufficient to be able to evaluate the cost effectiveness of the interventions. AUTHORS' CONCLUSIONS This review highlights the paucity of evidence for drug misusing offenders with co-occurring mental health problems. Two of the five trials showed some promising results for the use of therapeutic communities and aftercare, but only in relation to reducing subsequent re-incarceration. The studies overall, showed a high degree of statistical variation demonstrating a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. More evaluations are required to assess the effectiveness of interventions for drug-using offenders with co-occurring mental health problems.

Abstract
BACKGROUND Venous leg ulcers are a type of chronic wound affecting up to 1% of adults in developed countries at some point during their lives. Many of these wounds are colonised by bacteria or show signs of clinical infection. The presence of infection may delay ulcer healing. Two main strategies are used to prevent and treat clinical infection in venous leg ulcers: systemic antibiotics and topical antibiotics or antiseptics. OBJECTIVES The objective of this review was to determine the effects of systemic antibiotics and topical antibiotics and antiseptics on the healing of venous ulcers; review authors also examined the effects of these interventions on clinical infection, bacterial flora, bacterial resistance, ulcer recurrence, adverse effects, patient satisfaction, health-related quality of life and costs. SEARCH METHODS In May 2013, for this second update, we searched the Cochrane Wounds Group Specialised Register (searched 24 May 2013); the Cochrane Central Register of Controlled Trials (CENTRAL 2013, Issue 4); Ovid MEDLINE (1948 to Week 3 May 2013); Ovid MEDLINE (In-Process & Other Non-indexed Citations, 22 May 2013); Ovid EMBASE (1980 to Week 20 2013); and EBSCO CINAHL (1982 to 17 May 2013). No language or publication date restrictions were applied. SELECTION CRITERIA Randomised controlled trials (RCTs) recruiting people with venous leg ulceration, evaluating at least one systemic antibiotic, topical antibiotic or topical antiseptic that reported an objective assessment of wound healing (e.g. time to complete healing, frequency of complete healing, change in ulcer surface area) were eligible for inclusion. Selection decisions were made by two review authors while working independently. DATA COLLECTION AND ANALYSIS Information on the characteristics of participants, interventions and outcomes was recorded on a standardised data extraction form. In addition, aspects of trial methods were extracted, including randomisation, allocation concealment, blinding of participants and outcome assessors, incomplete outcome data and study group comparability at baseline. Data extraction and validity assessment were conducted by one review author and were checked by a second. Data were pooled when appropriate. MAIN RESULTS Forty-five RCTs reporting 53 comparisons and recruiting a total of 4486 participants were included, Many RCTs were small, and most were at high or unclear risk of bias. Ulcer infection status at baseline and duration of follow-up varied across RCTs. Five RCTs reported eight comparisons of systemic antibiotics, and the remainder evaluated topical preparations: cadexomer iodine (11 RCTs reporting 12 comparisons); povidone-iodine (six RCTs reporting seven comparisons); peroxide-based preparations (four RCTs reporting four comparisons); honey-based preparations (two RCTs reporting two comparisons); silver-based preparations (12 RCTs reporting 13 comparisons); other topical antibiotics (three RCTs reporting five comparisons); and other topical antiseptics (two RCTs reporting two comparisons). Few RCTs provided a reliable estimate of time to healing; most reported the proportion of participants with complete healing during the trial period. Systemic antibioticsMore participants were healed when they were prescribed levamisole (normally used to treat roundworm infection) compared with placebo: risk ratio (RR) 1.31 (95% CI 1.06 to 1.62). No between-group differences were detected in terms of complete healing for other comparisons: antibiotics given according to antibiogram versus usual care; ciprofloxacin versus standard care/placebo; trimethoprim versus placebo; ciprofloxacin versus trimethoprim; and amoxicillin versus topical povidone-iodine. Topical antibiotics and antisepticsCadexomer iodine: more participants were healed when given cadexomer iodine compared with standard care. The pooled estimate from four RCTs for complete healing at four to 12 weeks was RR 2.17 (95% CI 1.30 to 3.60). No between-group differences in complete healing were detected when cadexomer iodine was compared with the following: hydrocolloid dressing; paraffin gauze dressing; dextranomer; and silver-impregnated dressings.Povidone iodine: no between-group differences in complete healing were detected when povidone-iodine was compared with the following: hydrocolloid; moist or foam dressings according to wound status; and growth factor. Time to healing estimates for povidone-iodine versus dextranomer, and for povidone-iodine versus hydrocolloid, were likely to be unreliable.Peroxide-based preparations: four RCTs reported findings in favour of peroxide-based preparations when compared with usual care for surrogate healing outcomes (change in ulcer area). There was no report of complete healing.Honey-based preparations: no between-group difference in time to healing or complete healing was detected for honey-based products when compared with usual care.Silver-based preparations: no between-group differences in complete healing were detected when 1% silver sulphadiazine ointment was compared with standard care/placebo and tripeptide copper complex; or when different brands of silver-impregnated dressings were compared; or when silver-impregnated dressings were compared with non-antimicrobial dressings.Other topical antibiotics: data from one RCT suggested that more participants healed at four weeks when treated with an enzymatic cleanser (a non-antibiotic preparation) compared with a chloramphenicol-containing ointment (additional active ingredients also included in the ointment): RR 0.13 (95% CI 0.02 to 0.99). No between-group differences in complete healing were detected for framycetin sulphate ointment versus enzymatic cleanser; chloramphenicol ointment versus framycetin sulphate ointment; mupirocin ointment versus vehicle; and topical antibiotics given according to antibiogram versus an herbal ointment.Other topical antiseptics: data from one RCT suggested that more participants receiving an antiseptic ointment (ethacridine lactate) had responsive ulcers (defined as > 20% reduction in area) at four weeks when compared with placebo: RR 1.45 (95% CI 1.21 to 1.73). Complete healing was not reported. No between-group difference was detected between chlorhexidine solution and usual care. AUTHORS' CONCLUSIONS At present, no evidence is available to support the routine use of systemic antibiotics in promoting healing of venous leg ulcers. However, the lack of reliable evidence means that it is not possible to recommend the discontinuation of any of the agents reviewed. In terms of topical preparations, some evidence supports the use of cadexomer iodine. Current evidence does not support the routine use of honey- or silver-based products. Further good quality research is required before definitive conclusions can be drawn about the effectiveness of povidone-iodine, peroxide-based preparations, ethacridine lactate, chloramphenicol, framycetin, mupirocin, ethacridine or chlorhexidine in healing venous leg ulceration. In light of the increasing problem of bacterial resistance to antibiotics, current prescribing guidelines recommend that antibacterial preparations should be used only in cases of clinical infection, not for bacterial colonisation.

Abstract
BACKGROUND The review represents one in a family of four reviews focusing on a range of different interventions for drug-using offenders. This specific review considers pharmacological interventions aimed at reducing drug use and/or criminal activity for illicit drug-using offenders. OBJECTIVES To assess the effectiveness of pharmacological interventions for drug-using offenders in reducing criminal activity and/or drug use. SEARCH METHODS Fourteen electronic bibliographic databases (searched between 2004 and 21 March 2013) and five additional Web resources (searched between 2004 and 11 November 2011) were searched. Experts in the field were contacted for further information. SELECTION CRITERIA Randomised controlled trials assessing the efficacy of any pharmacological interventions for reducing, eliminating or preventing relapse in drug-using offenders were included. Data on the cost and cost-effectiveness of interventions were reported. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as expected by The Cochrane Collaboration. MAIN RESULTS A total of 76 trials across the four reviews were identified. After a process of prescreening had been completed, 17 trials were judged to meet the inclusion criteria for this specific review (six of the 17 trials are awaiting classification for the review). The remaining 11 trials contained a total of 2,678 participants. Nine of the eleven studies used samples with a majority of men. The interventions (buprenorphine, methadone and naltrexone) were compared to non pharmacological treatments (e.g., counselling) and other pharmacological drugs. The methodological trial quality was poorly described, and most studies were rated as 'unclear' by the reviewers. The biggest threats to risk of bias were generated through blinding (performance and detection bias) and incomplete outcome data (attrition bias). When combined, the results suggest that pharmacological interventions do significantly reduce subsequent drug use using biological measures, (three studies, 300 participants, RR 0.71 (95% CI 0.52 to 0.97)), self report dichotomous data (three studies, 317 participants, RR 0.42, (95% CI 0.22 to 0.81)) and continuous measures (one study, MD -59.66 (95% CI -120.60 to 1.28)) . In the subgroups analysis for community setting, (two studies, 99 participants: RR 0.62 (95% CI 0.35 to 1.09)) and for secure establishment setting, (one study, 201 participants: RR 0.76 (95% CI 0.52 to 1.10)), the results are no longer statistically significant. Criminal activity was significantly reduced favouring the dichotomous measures of re arrest, (one study, 62 participants, RR 0.60 (95% CI 0.32 to 1.14)), re-incarceration, (three studies, 142 participants, RR 0.33 (95% CI 0.19 to 0.56)) and continuous measures (one study, 51 participants, MD -74.21 (95% CI -133.53 to -14.89)). Findings on the effects of individual pharmacological interventions on drug use and criminal activity show mixed results. Buprenorphine in comparison to a non pharmacological treatment seemed to favour buprenorphine but not significantly with self report drug use, (one study, 36 participants, RR 0.58 (95% CI 0.25 to 1.35)). Methadone and cognitive behavioural skills in comparison to standard psychiatric services, did show a significant reduction for self report dichotomous drug use (one study, 253 participants, RR 0.43 (95% CI 0.33 to 0.56)) but not for self report continuous data (one study 51 participants) MD -0.52 (95% CI -1.09 to 0.05)), or re incarceration RR 1.23 (95% CI 0.53 to 2.87)). Naltrexone was favoured significantly over routine parole and probation for re incarceration (two studies 114 participants, RR 0.36 (95% CI 0.19 to 0.69)) but no data was available on drug use. Finally, we compared each pharmacological treatment to another. In each case we compared methadone to: buprenorphine, diamorphine and naltrexone. No significant differences were displayed for either treatment for self report dichotomous drug use (one study, 193 participants RR 1.23 (95% CI 0.86 to 1.76)), continuous measures of drug use MD 0.70 (95% CI -5.33 to 6.73) or criminal activity RR 1.25 (95% CI 0.83 to 1.88)) between methadone and buprenorphine. Similiar results were found for comparisons with Diamorphine with no significant differences between the drugs for self report dichotomous drug use for arrest (one study, 825 participants RR 1.25 (95% CI 1.03-1.51)) or Naltrexone for dichotomous measures of re incarceration (one study, 44 participants, RR 1.10 (95% CI 0.37 to 3.26)), and continuous outcome measure of crime MD -0.50 (95% CI -8.04 to 7.04)) or self report drug use MD 4.60 (95% CI -3.54 to 12.74)). AUTHORS' CONCLUSIONS Pharmacological interventions for drug-using offenders do appear to reduce overall subsequent drug use and criminal activity (but to a lesser extent). No statistically significant differences were displayed by treatment setting. Individual differences are displayed between the three pharmacological interventions (buprenorphine, methadone and naltrexone) when compared to a non pharmacological intervention, but not when compared to each other. Caution should be taken when interpreting these findings, as the conclusions are based on a small number of trials, and generalisation of these study findings should be limited mainly to male adult offenders. Additionally, many studies were rated at high risk of bias because trial information was inadequately described.

Abstract
BACKGROUND Venous leg ulcers are a common and recurring type of chronic or complex wound that are associated with considerable cost to patients and to healthcare providers. Primary wound contact dressings are usually applied beneath compression devices with the aim of aiding healing. Foam dressings are used frequently, and a variety of foam products is available on the market. The evidence base to guide dressing choice, however, is sparse. OBJECTIVES To determine the effects of foam dressings on the healing of venous leg ulcers. SEARCH METHODS In October 2012 we searched The Cochrane Wounds Group Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); the Database of Abstracts of Reviews of Effects (DARE) (The Cochrane Library); the Economic Evaluation Database (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; EBSCO CINAHL. There were no restrictions based on language or date of publication. SELECTION CRITERIA We included published or unpublished randomised controlled trials (RCTs) that evaluated the effects of any type of foam dressing in the treatment of venous ulcers. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, data extraction and risk of bias assessment. Meta-analysis was undertaken when deemed feasible and appropriate. MAIN RESULTS Twelve RCTs (1023 participants) reporting 14 comparisons were included in this review. There was no difference in healing outcomes between hydrocellular foam dressings and polyurethane foam dressings (three RCTs). Pooled data across five RCTs (418 participants) showed no statistically significant difference between foam dressings and hydrocolloid dressings in the proportion of ulcers healed at 12 to 16 weeks (risk ratio (RR) 1.00, 95% confidence interval (CI) 0.81 to 1.22). No statistically significant between-group differences in healing outcomes were detected when foam dressings were compared with: paraffin gauze (two RCTs); hydrocapillary dressing (one RCT); knitted viscose dressing (one RCT); and protease modulating matrix (one RCT). No statistically significant between-group differences in the proportion of participants experiencing adverse events were detected when hydrocellular foam dressings were compared with polyurethane foam dressings, or when foam dressings were compared with hydrocapillary, hydrocolloid, or knitted viscose dressings (one RCT for each comparison). Six RCTs were considered as being at overall high risk of bias, and the remaining six RCTs were considered to be at overall unclear risk of bias. No included RCT had an overall low risk of bias. AUTHORS' CONCLUSIONS The current evidence base does not suggest that foam dressings are more effective in the healing of venous leg ulcers than other wound dressing treatments. The evidence in this area is of low quality. Further evidence is required from well-designed and rigorously-conducted RCTs, that employ methods to minimise bias and report them clearly, before any definitive conclusions can be made regarding the efficacy of foam dressings in the management of venous leg ulcers.

Abstract
BACKGROUND Venous leg ulcers are a common and recurring type of chronic, complex wound associated with considerable cost to patients and healthcare providers. To aid healing, primary wound contact dressings are usually applied to ulcers beneath compression devices. Alginate dressings are used frequently and there is a variety of alginate products on the market, however, the evidence base to guide dressing choice is sparse. OBJECTIVES To determine the effects of alginate dressings compared with alternative dressings, non-dressing treatments or no dressing, with or without concurrent compression therapy, on the healing of venous leg ulcers. SEARCH METHODS We searched The Cochrane Wounds Group Specialised Register (searched 30 November 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 11); The NHS Economic Evaluation Database (NHS EED) (The Cochrane Library 2012, Issue 5); Ovid MEDLINE (1946 to November Week 2 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations November 29, 2012); Ovid EMBASE (1980 to 2011 Week 11); and EBSCO CINAHL (1982 to 23 November 2012). There were no restrictions based on language or date of publication. SELECTION CRITERIA Published or unpublished randomised controlled trials (RCTs) that evaluated the effects of any type of alginate dressing in the treatment of venous ulcers were included. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, data extraction and risk of bias assessment. Meta-analysis was undertaken when deemed feasible and appropriate. MAIN RESULTS Five RCTs (295 participants) were included in this review. Overall risk of bias was high for two RCTs and unclear for three. One RCT compared different proprietary alginate dressings (20 participants), three compared alginate and hydrocolloid dressings (215 participants), and one compared alginate and plain non-adherent dressings (60 participants). Follow-up periods were six weeks in three RCTs and 12 weeks in two. No statistically significant between-group differences were detected for any comparison, for any healing outcome. Meta-analysis was feasible for one comparison (alginate and hydrocolloid dressings), with data from two RCTs (84 participants) pooled for complete healing at six weeks: risk ratio 0.42 (95% confidence interval 0.14 to 1.21). Adverse event profiles were generally similar between groups (not assessed for alginate versus plain non-adherent dressings). AUTHORS' CONCLUSIONS The current evidence base does not suggest that alginate dressings are more or less effective in the healing of venous leg ulcers than hydrocolloid or plain non-adherent dressings, and there is no evidence to indicate a difference between different proprietary alginate dressings. However, the RCTs in this area are considered to be of low or unclear methodological quality. Further, good quality evidence is required from well designed and rigorously conducted RCTs that employ - and clearly report on - methods to minimise bias, prior to any definitive conclusions being made regarding the efficacy of alginate dressings in the management of venous leg ulcers.

Abstract
BACKGROUND Venous leg ulcers affect up to 1% of people at some time in their lives and are often painful. The main treatments are compression bandages and dressings. Topical treatments to reduce pain during and between dressing changes are sometimes used. OBJECTIVES To determine the effects of topical agents or dressings for pain in venous leg ulcers. SEARCH METHODS For this third update the following databases were searched: Cochrane Wounds Group Specialised Register (searched 9 May 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 4); Ovid MEDLINE (2009 to April Week 4 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations May 08, 2012); Ovid EMBASE (2009 to 2012 Week 18); and EBSCO CINAHL (2009 to May 2 2012). No date or language restrictions were applied. SELECTION CRITERIA Published or unpublished randomised controlled trials (RCTs) that evaluated the effects of topical agents or dressing for the treatment of pain in venous ulcers were included. DATA COLLECTION AND ANALYSIS Two review authors independently performed trial selection, data extraction and risk of bias assessment. MAIN RESULTS Six trials (343 participants) evaluated Eutectic Mixture of Local Anaesthetics (EMLA): lidocaine-prilocaine cream for the pain associated with ulcer debridement. The between-group difference in pain measured on a 100 mm scale was statistically significant in favour of EMLA (MD -20.65, 95% CI -12.19 to -29.11). No significant between-group differences in burning or itching were observed.Two trials (470 participants with venous leg ulcers) evaluated ibuprofen slow-release foam dressings for persistent venous leg ulcer pain. Compared with local best practice, significantly more participants in the ibuprofen dressing group achieved the outcome of >50% of the total maximum pain relief score between day 1 and day 5 than participants in the local best practice group (RR 1.63, 95% CI 1.24 to 2.15). The number needed to treat was 6 (95% CI 4 to 12). In the second trial, compared with an identical non-ibuprofen foam dressing, there was no statistically significant difference in the proportion of participants experiencing slight to complete pain relief on the first evening of treatment.Limited data were available to assess healing rates or adverse events. AUTHORS' CONCLUSIONS There is some evidence to suggest that ibuprofen dressings may offer pain relief to people with painful venous leg ulcers. EMLA (5%) appears to provide effective pain relief during the debridement of venous leg ulcers. Further research should consider standardised pain assessment methods and assess both the effect on ulcer healing and the impact of long term use of these treatments.

Abstract
BACKGROUND Chronic wounds are common and present a health problem with significant effect on quality of life. Various pathologies may cause tissue breakdown, including poor blood supply resulting in inadequate oxygenation of the wound bed. Hyperbaric oxygen therapy (HBOT) has been suggested to improve oxygen supply to wounds and therefore improve their healing. OBJECTIVES To assess the benefits and harms of adjunctive HBOT for treating chronic ulcers of the lower limb. SEARCH METHODS For this first update we searched the Cochrane Wounds Group Specialised Register (searched 12 January 2012); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 4); Ovid MEDLINE (1950 to January Week 1 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, 11 July 2012); Ovid EMBASE (1980 to 2012 Week 01); and EBSCO CINAHL (1982 to 6 January 2012). SELECTION CRITERIA Randomised controlled trials (RCTs) comparing the effect on chronic wound healing of therapeutic regimens which include HBOT with those that exclude HBOT (with or without sham therapy). DATA COLLECTION AND ANALYSIS Three review authors independently evaluated the risk of bias of the relevant trials using the Cochrane methodology and extracted the data from the included trials. We resolved any disagreement by discussion. MAIN RESULTS We included nine trials (471 participants). Eight trials (455 participants) enrolled people with a diabetic foot ulcer: pooled data of three trials with 140 participants showed an increase in the rate of ulcer healing (risk ratio (RR) 5.20, 95% confidence interval (CI) 1.25 to 21.66; P = 0.02) with HBOT at six weeks but this benefit was not evident at longer-term follow-up at one year. There was no statistically significant difference in major amputation rate (pooled data of five trials with 312 participants, RR 0.36, 95% CI 0.11 to 1.18). One trial (16 participants) considered venous ulcers and reported data at six weeks (wound size reduction) and 18 weeks (wound size reduction and number of ulcers healed) and suggested a significant benefit of HBOT in terms of reduction in ulcer area only at six weeks (mean difference (MD) 33.00%, 95% CI 18.97 to 47.03, P < 0.00001). We did not identify any trials that considered arterial and pressure ulcers. AUTHORS' CONCLUSIONS In people with foot ulcers due to diabetes, HBOT significantly improved the ulcers healed in the short term but not the long term and the trials had various flaws in design and/or reporting that means we are not confident in the results. More trials are needed to properly evaluate HBOT in people with chronic wounds; these trials must be adequately powered and designed to minimise all kinds of bias.

Abstract
Our objective was to assess the effects of differing modes of impact exercise on bone density at the hip and spine in premenopausal women through systematic review and meta-analysis. Electronic databases, key journals and reference lists were searched for controlled trials investigating the effects of impact exercise interventions on lumbar spine (LS), femoral neck (FN) and total hip (TH) bone mineral density (BMD) in premenopausal women. Exercise protocols were categorised according to impact loading characteristics. Weighted mean difference (WMD) meta-analyses were undertaken. Heterogeneity amongst trials was assessed. Fixed and random effects models were applied. Inspection of funnel plot symmetry was performed. Trial quality assessment was also undertaken. Combined protocols integrating odd- or high-impact exercise with high-magnitude loading (resistance exercises), were effective in increasing BMD at both LS and FN [WMD (fixed effect) 0.009 g cm(-2) 95% CI (0.002-0.015) and 0.007 g cm(-2) 95% CI (0.001-0.013); P = 0.011 and 0.017, respectively]. High-impact only protocols were effective on femoral neck BMD [WMD (fixed effect) 0.024 g cm(-2) 95% CI (0.002-0.027); P < 0.00001]. Funnel plots showed some asymmetry for positive BMD outcomes. Insufficient numbers of protocols assessing TH BMD were available for assessment. Exercise programmes that combine odd- or high-impact activity with high-magnitude resistance training appear effective in augmenting BMD in premenopausal women at the hip and spine. High-impact-alone protocols are effective only on hip BMD in this group. However, diverse methodological and reporting discrepancies are evident in published trials.

Abstract
Whilst exercise is recommended for optimum bone health in adult women, there are few systematic reviews of the efficacy of walking as singular exercise therapy for postmenopausal bone loss. The aim of this study was to assess the effects of prescribed walking programmes on bone mineral density (BMD) at the hip and spine in postmenopausal women and to determine if effects are modified by variations in protocol design. We undertook a systematic review and meta-analysis of randomised (RCTs) and non-randomised controlled trials. Electronic bibliographic databases, key journals and reference lists of reviews and articles were searched to identify studies for inclusion. Randomised and non-randomised controlled trials assessing the effects of walking on lumbar spine, femoral neck and total hip BMD, measured by radiographic techniques, among sedentary postmenopausal women were eligible for inclusion. Two independent reviewers assessed studies for eligibility. Reported absolute BMD outcomes were combined in the analysis. Weighted mean differences (WMD) were calculated using a fixed and random-effects models. Heterogeneity among trials was examined using the Q statistic and I2 methods. Potential publication bias was assessed through funnel plot inspection. Assessment of trial quality was also performed using the widely used instrument devised by Jadad et al. [Jadad AR, Moore RA, Carroll D, Jenkinson C, Reynolds DJM, Gavaghan DJ, et al. Assessing the quality of reports of randomized clinical trials: Is blinding necessary? Cont Clin Trials 1996; 17:1-12]. Eight trials were eligible for inclusion. Treatment duration ranged from 6 to 24 months. All eight trials reported BMD data at the lumbar spine following walking interventions among postmenopausal women. Meta-analysis showed no significant change in BMD at this site [WMD (fixed-effect) 0.007 g/cm2 95% CI (-0.001 to 0.016); P=0.09)]. BMD data at the femoral neck were available from five trials among postmenopausal women. Results were inconsistent (I2=51.4%) in showing a positive effect of walking on BMD at this site [WMD (random-effects) 0.014 g/cm2 95% CI (0.000 to 0.028); P=0.05). Insufficient data were available for meta-analysis of the total hip site. Funnel plots showed some asymmetry for negative lumbar spine BMD outcomes. Trial quality scores ranged from 0 to 3 from the Jadad scale of 0 to 5. We conclude that regular walking has no significant effect on preservation of BMD at the spine in postmenopausal women, whilst significant positive effects at femoral neck are evident. However, diverse methodological and reporting discrepancies are apparent in the published trials on which these conclusions are based. Other forms of exercise that provide greater targeted skeletal loading may be required to preserve bone mineral density in this population.

Abstract
Regular weight-bearing physical activity has been widely recommended for adult women and may be beneficial in preserving bone mineral density (BMD). However, there is conflicting evidence regarding the effects of resistance training on BMD in premenopausal women. Novel systematic review and meta-analysis evidence is presented on the effects of progressive high-intensity resistance training on BMD in premenopausal women. Structured computer searches of MEDLINE, EMBASE, PubMed, Web of Science, SportDiscus and Evidence Based Medicine Reviews Multifile were undertaken along with hand-searching of key journals and reference lists to locate relevant studies published up to September 2004. Criteria for included studies were published controlled studies and randomised controlled trials (RCTs) evaluating the effects of progressive, high-intensity resistance training studies on BMD in premenopausal women. Two authors reached consensus on all included and excluded studies. Study outcomes for analysis were radiographic BMD assessment from first follow-up at lumbar spine and femoral neck. Primary outcomes for analysis were absolute changes in BMD g/cm(2) at lumbar spine and femoral neck. Relative changes (percentage change) in BMD at lumbar spine were also assessed. Data were extracted from studies including study design, participant characteristics and treatment mode, intensity and duration, using electronic data extraction forms. Where necessary, relevant information was obtained by contacting study authors. Methodological quality of studies was assessed using a well recognised three-question instrument designed to assess bias. Informal assessment for small sample study effects and potential bias was undertaken through visual inspection of funnel plots. The weighted mean difference method (inverse of the variances) was used for combining study group estimates. Quantification of the effect of heterogeneity among study outcomes was assessed using the I(2) statistic. Random effects and fixed-effect models were applied according to observed study heterogeneity. Comparisons resulting in I(2) > 50.0% were considered heterogeneous. Where heterogeneity was observed, a random effects model was applied. Pooled estimates of effect were calculated using the Cochrane Collaboration's Review Manager (RevMan) 4.2.1 software.High-intensity progressive resistance training was shown to be efficacious in increasing absolute BMD at the lumbar spine (p < 0.00001) but not the femoral neck (p = 0.78) in premenopausal women. The weighted mean difference (WMD) using a fixed-effect model for six controlled trials investigating the lumbar spine BMD change was 0.014 g/cm(2) (95% CI 0.009, 0.019; p < 0.00001). The relative BMD change for this site was 0.98% (WMD [random effects], 95% CI 0.49, 3.91%; p = 0.04). In contrast, studies evaluating femoral neck BMD changes showed no significant BMD change (WMD [fixed effect], 0.001 g/cm(2) 95% CI -0.006, 0.008; p = 0.78). Funnel plot inspection of lumbar spine effects indicated that smaller studies demonstrated larger treatment effects. An asymmetry towards studies with positive BMD outcomes was also noted. The methodological quality score of all included studies was low and no study presented a valid intention-to-treat accounting for participant drop-out (attrition). As such, the modest overall treatment effects for resistance training on BMD among premenopausal women observed in this review may be biased and should be interpreted with caution. It is concluded that further RCTs of resistance training of sufficiently long duration and providing optimum type, intensity and volume of loading, with intention-to-treat analysis are now required.
