Abstract
PURPOSE This study aimed to explore individuals' experiences of return to work (RTW) following minor to serious road traffic injury (RTI) in Queensland, Australia; seek their recommendations if any, on how to provide support for RTW after RTI; and identify the strategies and resources used to return and remain at work after their RTI. METHODS The interpretive description methodological approach was used. Semi-structured interviews were conducted with eligible participants (n = 18) aged 18-65 y who had experienced a minor to serious RTI at least 6 months earlier. Thematic analysis was used to analyse the data. RESULTS Five themes emerged: (1) physical and mental consequences of RTI negatively impact RTW; (2) money matters; (3) RTW support makes a difference; (4) feeling alone and confused in the RTW process; and (5) several strategies and resources helped with return/stay at work after RTI. Regular contact and cooperation with employers and insurers, job modifications, and using social media to obtain information and social support were helpful RTW strategies. Participants recommended timely and appropriate medical care, financial assistance, and educational support. CONCLUSIONS Policy changes to reduce financial stress, increase employer support, and improve injured individuals' knowledge following a RTI are recommended in jurisdictions operating a fault-based scheme.IMPLICATIONS FOR REHABILITATIONThis study identified several factors that can influence return to work (RTW) following minor to serious road traffic injuries (RTIs) in a jurisdiction operating a fault-based compensation scheme.Legislative changes that provide financial assistance to all injured people regardless of their fault-status could reduce financial stress arising from reduced work ability following a road traffic injury.Increasing employer' awareness of the importance of return to work for those with road traffic injuries and reimbursement for possible expenses of providing RTW support for these individuals could increase employability of injured people following RTI.Improving injured individuals' knowledge about return-to-work processes after a road traffic injury could accelerate recovery and return to work.

Abstract
PURPOSE To evaluate the existing evidence surrounding the effect of rehabilitation therapies on quality of life (QOL) and function of individuals with a lower-limb amputation and experiencing phantom limb pain (PLP). METHODS This review followed Preferred Reporting Items for Systematic reviews and Meta-Analyses methodology. Four databases were searched with key terms that covered 4 broad areas: phantom limb, lower-limb amputation, rehabilitation interventions, and randomized controlled trial (no date limits). Outcomes of either function or QOL in people receiving rehabilitation for PLP were included. The RoB2.0 risk-of-bias tool was used to rate quality. RESULTS Five studies were included, reporting on QOL (n = 5) and function (n = 3), using interventions including mirror therapy, phantom exercises, and muscle relaxation. The evidence was mixed in direction and significance, and this was likely attributed to by the heterogeneity of interventions and types of outcomes as well as incomplete reporting. There was very low certainty in the effect of these rehabilitation interventions to affect QOL or function. CONCLUSION The overall effect of rehabilitation interventions on QOL and function is inconclusive because of the variable results across the included randomized controlled trials. More research is needed to explore the impact of interventions beyond the outcome of pain and to establish a clearer conclusion. Including measures of QOL and function as well as pain in studies with people with PLP is encouraged.

Abstract
BACKGROUND The ability to return to work and remain at work is an important recovery milestone after a cancer diagnosis. With the projected number of colorectal cancer patients of working age likely to increase, it is important to identify when a person is ready to resume work. There are many employment-related tools available to help people return to work after injury or illness; however, it is unknown which may be suitable for a person with colorectal cancer. AIM To identify tools related to employment readiness in colorectal cancer survivors and to chart the relevant factors of employment assessed by these tools. METHOD Literature searches were performed in PubMed, CINAHL, Embase and Medline, the Cochrane library and PsycINFO using search terms around cancer, survivorship and employment to identify all peer-reviewed articles published in English up to June 2022. RESULTS Thirty-five studies used a total of 77 tools focused on assessing employment issues experienced by people with cancer in general. Four tools were used with colorectal cancer survivors. None considered all relevant employment-related factors for colorectal cancer survivors. CONCLUSION Tools used to identify return-to-work and remain-at-work were not specific to colorectal cancer. There are a range of existing tools that collate some, but not all, of the domains and outcome criteria required to meet the employment needs of colorectal cancer survivors. To optimize work outcomes for the working colorectal cancer population, a specified tool is warranted.

Abstract
PURPOSE This qualitative study conducted in Queensland, Australia aimed to explore various stakeholders' perspectives on (1) the barriers and facilitators of Return to Work (RTW) for injured persons following minor to serious Road Traffic Injuries (RTI) in a fault-based scheme, and to investigate the changes needed to better support RTW following RTI. METHODS The study was performed using the Interpretive Description methodological approach. Data were collected during interviews (n = 17), one focus group (n = 4), and an open-ended survey (n = 10) with five categories of stakeholders: treating health providers, workplace representatives, legal representatives, rehabilitation advisors, and insurers. Participants were eligible to participate if they had at least one year of employment history in their respective profession in Queensland, Australia, and were experienced in assisting the RTW of people with RTI. Thematic analysis was used to analyse the data. RESULTS Seven themes were extracted reflecting the barriers and facilitators of RTW along with stakeholders' recommendations to address these barriers. These themes were: (1) knowledge is power; (2) stakeholder expertise; (3) early and appropriate treatment matters; (4) insurers could do better; (5) necessity of employers' support; (6) fix the disjointed system; (7) importance of individual factors pre- and post- injury. The main barriers identified were stakeholders' insufficient communication and knowledge on RTW process following RTI. CONCLUSIONS Individual and system barriers identified in this study suggest that RTW after RTI occurs in a complex system requiring the commitment of all stakeholders. This is particularly important for managing knowledge-related barriers by provision of high quality and easily accessible information about the RTW process, disability schemes, and the nature of RTI.

Abstract
OBJECTIVES To determine the impact of a 12-week ergonomic/exercise programme compared with an ergonomic/health education programme on the development of neck pain in office workers over 12 months. METHODS This cluster-randomised trial prospectively recruited office workers from public and private organisations. Only non-neck pain cases at baseline were included (n=484). All participants received an ergonomic workstation review then randomly allocated to receive a neck/shoulder progressive exercise programme (20 min, 3 ×/week; intervention group) or health education sessions (60 min, 1 ×/week; active control) for 12 weeks. Generalised estimating equations evaluated group differences in the point prevalence of neck pain cases (defined as those with a neck pain score of ≥3 on a 0 (no pain) to 9 (worst pain) scale) over time (3, 6, 9 and 12 months) with cumulative incidence of neck pain cases evaluated descriptively. RESULTS While no significant group × time interaction was evident, the 12-month point prevalence of neck pain cases in the intervention group (10%) was half that of the active control group (20%) (adjusted OR 0.46, 95% CI 0.21 to 1.01, p=0.05). Lower cumulative incidence of neck pain cases was observed in the intervention (17%) compared with active control group (30%) over the 12 months. CONCLUSIONS A combined ergonomics and exercise intervention may have more benefits in preventing neck pain cases in office workers than an ergonomic and health education intervention. Group differences were modest and should be interpreted with caution when considering strategies for primary prevention of neck pain in the office worker population.

Abstract
Purpose To identify factors impeding or facilitating Return to Work (RTW) after minor to serious musculoskeletal Road Traffic Injuries (RTI). Methods Six electronic databases were searched for studies published 1997-2020. Quantitative and qualitative studies were included if they investigated barriers or facilitators associated with RTW in people with minor to serious musculoskeletal RTI aged over 16 years. Methodological quality was assessed using McMaster Critical Review Form for Quantitative studies and McMaster Critical Review Form for Qualitative Studies. Results are presented narratively as meta-analysis was not possible. Results Eleven studies (10 quantitative and 1 qualitative) were included. There was strong evidence that individuals with higher overall scores on the (short-form or long-form) Örebro Musculoskeletal Pain Questionnaire (ÖMPQ) at baseline were less likely to RTW, and individuals with higher RTW expectancies at baseline were more likely to RTW after musculoskeletal RTI. There was weak evidence for higher disability levels and psychiatric history impeding RTW after musculoskeletal RTI. Conclusions Post-injury scores on the ÖMPQ and RTW expectancies are the most influential factors for RTW after minor to serious musculoskeletal RTI. There is a need to identify consistent measures of RTW to facilitate comparisons between studies.

Abstract
This study aimed to develop an industry-specific tool to identify risk of poor physical and mental recovery following minor to moderate injuries sustained in a road traffic crash (RTC). Existing tools are often designed for implementation by health professionals rather than insurer case managers who may not have a background in health. This study is a secondary analysis of a longitudinal cohort study using data collected at 2-6 months and 24 months post-RTC. Participants were claimants (n = 254; Mean age = 50 years; 65% female) with mild-moderate injuries recruited through the common-law 'fault-based' compulsory third party scheme in Queensland, Australia. Sociodemographic, functional and psychological health factors were collected at baseline (2-6 months post RTC) and used as potential predictors for physical and mental health-related quality of life (Short Form 36 v2) at the 2-year follow-up. The LASSO (Least Absolute Shrinkage and Selection Operator) analysis identified six disability items (from the World Health Organization Disability Assessment Schedule 2) to predict poor physical and one item to predict poor mental health-related quality of life. Logistic regressions of these items in addition to age and gender were used to develop a screening tool. Using the tool, 90% of those at risk of poor physical and 80% of those at risk of poor mental health-related quality of life were identified correctly. To conclude, this study presents an 8-item, context-specific tool to help injury managers identify individuals at risk of poor physical and mental health recovery following mild-moderate RTC-related injuries. The tool requires validation in a new cohort and confirmation of acceptability by end-users.

Abstract
Paritaprevir/ritonavir/ombitasvir and dasabuvir with or without ribavirin for 12 weeks are approved for treatment of chronic HCV genotype 1 infection. This study assessed the efficacy of shortened duration paritaprevir/ritonavir/ombitasvir and dasabuvir with or without ribavirin for 8 weeks among people with recent HCV infection. In this open-label single-arm trial conducted in Australia, England and New Zealand, adults with recent HCV (duration of infection <12 months) received paritaprevir/ritonavir/ombitasvir and dasabuvir (with weight-based ribavirin for genotypes 1a and 1, no subtype) for 8 weeks. The primary endpoint was sustained virological response at 12 weeks post-treatment (SVR12) in the intention-to-treat (ITT) population. Thirty people (median age 38 years, male 93%) commenced treatment (with ribavirin, 97%), of whom 77% (n = 23) were HIV-positive, 93% (n = 28) had genotype 1a infection and 53% (n = 16) had ever injected drugs. Median maximum ALT in the preceding 12 months was 433 IU/L (IQR 321, 1012). Acute clinical hepatitis with ALT > 10 x ULN was documented in 83% (n = 25); one participant (3%) had jaundice. At baseline, median estimated duration of infection was 30 weeks (range 11, 51), and median HCV RNA was 5.7 log10 IU/mL (range 2.7, 7.3). SVR12 was achieved in 97% (29/30; early discontinuation at week 2, n = 1; per protocol 100%, 29/29). No relapse or reinfection was observed. In conclusion, paritaprevir/ritonavir/ombitasvir and dasabuvir (with ribavirin) for eight weeks were highly effective among HIV-positive and HIV-negative individuals with recent HCV infection. These data support the use of this shortened duration direct-acting antiviral regimen in this population.

Abstract
BACKGROUND To achieve the World Health Organization hepatitis C virus (HCV) elimination targets, it is essential to increase access to treatment. Direct-acting antiviral (DAA) treatment can be provided in primary healthcare services (PHCS), improving accessibility, and, potentially, retention in care. Here, we describe our protocol for assessing the effectiveness of providing DAAs in PHCS, and the impact on the HCV care cascade. In addition, we reflect on the challenges of conducting a model of care study during a period of unprecedented change in HCV care and treatment. METHODS Consenting patients with HCV infection attending 13 PHCS in Australia or New Zealand are randomized to receive DAA treatment at the local tertiary institution (standard care arm), or their PHCS (intervention arm). The primary endpoint is the proportion commenced on DAAs and cured. Treatment providers at the PHCS include: hepatology nurses, primary care practitioners, or, in two sites, a specialist physician. All PHCS offer opioid substitution therapy. DISCUSSION The Prime Study is the first real-world, randomized, model of care study exploring the impact of community provision of DAA therapy on HCV-treatment uptake and cure. Although the study has faced challenges unique to this period of time characterized by changing treatment and service delivery, the data gained will be of critical importance in shaping health service policy that enables the elimination of HCV.

Abstract
BACKGROUND In the large randomised NEPTUNE study, peginterferon alfa-2a 180 μg/wk for 48 weeks produced higher hepatitis B e antigen (HBeAg) seroconversion rates 24 weeks post-treatment (36%) than a lower dose (90 μg/wk) and/or shorter duration (24 weeks) (range 14%-26%). AIM To determine seroconversion rates 5 years after completion of treatment in NEPTUNE. METHODS HBeAg-positive patients who completed 24 weeks' follow-up in NEPTUNE (with peginterferon alfa-2a 90 μg/wk × 24 weeks [group 1]; 180 μg/wk × 24 weeks [2]; 90 μg/wk × 48 weeks [3] or 180 μg/wk × 48 weeks [4]) were followed up. RESULTS Three hundred and eighty three of the 544 patients in the original study were enrolled in the long-term follow-up study. Many patients (196 overall; more in groups 1-3 than 4) received nucleos(t)ide analogues or immunomodulators during follow-up, and more patients had missing data at year 5 in groups 2 and 4 (48 weeks, 50/112) than in groups 1 and 3 (24 weeks, 23/103), which confounds the planned per-protocol analysis. HBeAg seroconversion rates in groups 1, 2, 3 and 4 at year 5 were 47.5%, 50.7%, 52.2% and 67.1%, respectively, (odds ratio for group 4 versus 1-3: 2.02; 95% CI 1.21, 3.38), using multiple imputation methods for missing measurements. CONCLUSION Seroconversion rates are durable for up to 5 years after completion of peginterferon alfa-2a therapy and, consistent with NEPTUNE, the results suggest that the licensed regimen (180 μg × 48 weeks) is more efficacious for HBeAg-positive patients than a lower dose and/or shorter treatment duration.

Abstract
The efficacy and safety of an investigational combination of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) plus sofosbuvir (SOF) ± ribavirin (RBV) in patients with HCV genotype 2 or 3 infection with or without cirrhosis was evaluated. Patients with HCV genotype 3 infection without cirrhosis were randomized to receive OBV/PTV/r + SOF ± RBV for 12 weeks; OBV/PTV/r + SOF + RBV was administered to genotype 3-infected patients with cirrhosis for 12 weeks and to genotype 2-infected patients without cirrhosis for either 6 or 8 weeks. Efficacy was assessed by sustained virologic response [HCV RNA <25 IU/mL] 12 weeks post-treatment (SVR12). Safety was assessed in all treated patients. In patients with genotype 3 infection with or without cirrhosis treated with 12 weeks of OBV/PTV/r + SOF ± RBV, the overall SVR12 rate was 98% (50/51), with no virologic failures. Patients with genotype 2 infection treated with OBV/PTV/r + SOF + RBV had SVR12 rates of 90% (9/10) and 44% (4/9) following 8- and 6-week treatment durations, respectively; failure to achieve SVR12 for these patients was due to relapse without baseline or treatment-emergent resistance-associated substitutions. Thus, the investigational combination of OBV/PTV/r with SOF ± RBV was well tolerated and achieved high SVR rates with no virologic failures in patients with genotype 3 infection. Combining direct-acting antivirals with complementary mechanisms of action and different viral targets may be an effective treatment strategy that may allow for shorter durations of therapy.

Abstract
BACKGROUND Hepatitis B e antigen (HBeAg) seroconversion is a treatment endpoint for HBeAg-positive CHB, and a necessary precursor to HBsAg loss. Biomarkers that predict serological outcomes would be useful. AIM To evaluate the utility of measuring HBeAg levels for predicting HBeAg seroconversion and HBsAg loss under long-term tenofovir (TDF) therapy. METHODS A total of 266 patients were enrolled into a phase III study of TDF vs adefovir (ADV) for 48 weeks in HBeAg-positive patients, followed by open-label TDF up to 384 weeks. Serum HBeAg levels were measured for subjects with samples available at both baseline and week 24 of treatment (n = 200). Analysis compared subjects who achieved HBeAg seroconversion by week 384 vs no HBeAg seroconversion. RESULTS HBeAg seroconversion rate was 52% by week 384. Time to HBeAg seroconversion was 80 weeks (IQR: 36-162). HBeAg decline at week 24 was associated with HBeAg seroconversion (1.63 vs 0.90 log10 PEIU/mL, P = .002). The optimal threshold for identifying HBeAg seroconversion was HBeAg decline ≥2.2 log10 PEIU/mL at week 24, with HBeAg seroconversion achieved by 76% of patients, compared to 44% if HBeAg decline <2.2 log10 (P < .0001). HBeAg decline ≥2.2 log10 PEIU/mL at week 24 was associated with HBsAg loss in genotype A or D patients (38% vs 15%, P = .03). Precore/basal core promotor variants were associated with lower baseline HBeAg levels, but not HBeAg seroconversion. CONCLUSION Decline in HBeAg levels by week 24 was associated with HBeAg seroconversion and HBsAg loss in HBeAg-positive chronic hepatitis B patients treated with long-term TDF.

Abstract
Portal hypertension is a predictor of liver-related clinical events and mortality in patients with hepatitis C and cirrhosis. The effect of interferon-free hepatitis C treatment on portal pressure is unknown. Fifty patients with Child-Pugh-Turcotte (CPT) A and B cirrhosis and portal hypertension (hepatic venous pressure gradient [HVPG] >6 mm Hg) were randomized to receive 48 weeks of open-label sofosbuvir plus ribavirin at Day 1 or after a 24-week observation period. The primary endpoint was sustained virologic response 12 weeks after therapy (SVR12) in patients who received ≥1 dose of treatment. Secondary endpoints included changes in HVPG, laboratory parameters, and MELD and CPT scores. A subset of patients was followed 48 weeks posttreatment to determine late changes in HVPG. SVR12 occurred in 72% of patients (33/46). In the 37 patients with paired HVPG measurements at baseline and the end of treatment, mean HVPG decreased by -1.0 (SD 3.97) mm Hg. Nine patients (24%) had ≥20% decreases in HVPG during treatment. Among 39 patients with pretreatment HVPG ≥12 mm Hg, 27 (69%) achieved SVR12. Four of the 33 (12%) patients with baseline HVPG ≥12 mm Hg had HVPG <12 mm Hg at the end of treatment. Of nine patients with pretreatment HVPG ≥12 mm Hg who achieved SVR12 and completed 48 weeks of follow-up, eight (89%) had a ≥20% reduction in HVPG, and three reduced their pressure to <12 mm Hg. Patients with chronic HCV and compensated or decompensated cirrhosis who achieve SVR can have clinically meaningful reductions in HVPG at long-term follow-up. (EudraCT 2012-002457-29).

Abstract
Elbasvir (EBR; HCV NS5A inhibitor) and grazoprevir (GZR; HCV NS3/4A protease inhibitor) are approved as a fixed-dose combination to treat patients chronically infected with HCV genotypes 1 and 4. During the development programme and supported by in vitro potency, the efficacy of EBR+GZR was assessed in HCV GT3-infected patients. This study's aim was to determine the efficacy and tolerability of 12 or 18 weeks of EBR+GZR with ribavirin (RBV) in treatment-naïve, noncirrhotic HCV GT3-infected patients. Randomized patients received open-label EBR (50 mg once daily) + GZR (100 mg once daily) + RBV. The primary efficacy objective was to evaluate the sustained virologic response rates 12 weeks after the end of all study therapy (SVR12). SVR12 rates (95% confidence interval) were 45.0% (23.1, 68.5) and 57.1% (34.0, 78.2) after treatment with EBR+GZR+RBV for 12 weeks or 18 weeks, respectively. On-treatment virologic failure was observed in 41% (17 of 41) of patients. At virologic failure, resistance-associated substitutions (RASs) with a >five-fold shift in potency occurred in the NS3 region in six (35%) patients and in the NS5A region in 16 (94%) patients. The most common RAS at virologic failure was Y93H in NS5A which was identified in 13 of 17 (76%) patients. The efficacy of EBR+GZR+RBV was suboptimal in HCV GT3-infected patients due to a high rate of on-treatment virologic failure and treatment-emergent RASs which demonstrates an inadequate barrier to the development of GT3 resistance. However, rapid viral clearance demonstrated the antiviral activity of EBR+GZR+RBV in GT3-infected patients.clinicaltrials.gov: NCT01717326.

Abstract
High rates of sustained virologic response at post-treatment week 12 (SVR12) were achieved in six phase 3 trials of ombitasvir (OBV, an NS5A inhibitor), paritaprevir (an NS3/4A protease inhibitor) co-dosed with ritonavir (PTV/r) + dasabuvir (DSV, an NS5B RNA polymerase inhibitor) (ie, 3D regimen) with or without ribavirin (RBV) in adults with chronic genotype (GT) 1 hepatitis C virus (HCV) infection. We assessed whether time to first HCV RNA value below the lower limit of quantification in patients with and without cirrhosis was associated with achievement of SVR12. Data were analysed from GT1-infected patients enrolled in six phase 3 studies of 3D ± RBV. Patients who experienced non-virologic failure were excluded from analysis. HCV RNA was determined using the Roche COBAS TaqMan RT-PCR assay (lower limit of quantification, LLOQ =25 IU/mL). SVR12 was analysed by week of first HCV RNA suppression, defined as HCV RNA <LLOQ. The analysis included a total of 2027 patients. Cumulative proportions of subjects with initial HCV RNA suppression <LLOQ at weeks 1, 2, 4 and 6 were 31%, 81%, 99% and 100%, respectively. SVR12 was achieved by 98%, 97%, 98% and 92% of patients with initial suppression at Weeks 1, 2, 4 and 6, respectively (P=.42, trend test). Across six phase 3 trials of 3D ± RBV, most patients achieved viral suppression by week 2. Time to viral suppression was not associated with subsequent achievement of SVR12, suggesting that on-treatment virologic monitoring may not be necessary with this regimen.

Abstract
Grazoprevir (GZR) is a second-generation hepatitis C virus NS3/4A protease inhibitor. The aim of this study was to evaluate GZR plus ribavirin (RBV) in patients with HCV GT1 infection. Noncirrhotic, IL28B CC patients with HCV genotype 1 infection were randomized to GZR 100 mg once daily and RBV for 12 or 24 weeks. Patients in the 12-week arm with detectable HCV RNA at treatment week 4 (TW4) had treatment extended to 24 weeks (response-guided therapy, RGT). The primary endpoint was sustained virologic response (SVR12) at follow-up week 12 (HCV RNA <25 IU/mL) in the per-protocol (PP) population (excluding patients with important protocol deviations). Twenty-six patients were randomized and 22 were included in the PP population. SVR12 was 58.3% (7 of 12) and 90% (9 of 10) in the RGT and 24-week arms, respectively. Seven PP patients had virologic failure, including one patient in the 24-week arm who relapsed after follow-up week 12. All three breakthrough patients had wild-type (WT) virus at baseline and developed breakthrough at TW6 or TW12 with Y56H, A156T and D168A/N mutations. Of the five relapse patients, four had WT at baseline (at relapse three had WT and one had V55A and D168A), and one had S122A/T at baseline and S122T at relapse. There were no serious adverse events (AEs), discontinuations due to AEs or grade 3/4 elevations in total and/or direct bilirubin. Grazoprevir plus RBV was associated with a rapid and sustained suppression of HCV RNA. These results support further evaluation of grazoprevir-based regimens (NCT01716156; protocol P039).

Abstract
BACKGROUND Older adults hospitalized with fragility fractures are at high risk of negative events that can culminate in re-presentations to hospital emergency departments or readmissions to hospital. This systematic review aimed to identify patient, clinical, or hospital-related factors that are identifiable at the index admission and that may be associated with re-presentations to hospital emergency departments or hospital readmissions in older adults following fragility fractures. METHODS Four electronic databases (PubMed, CINAHL, Embase, and Scopus) were searched. A suite of search terms identified peer-reviewed English-language articles that examined potential correlates of hospital re-presentation in older adults (mean age ≥ 65 years) who were discharged from hospital following treatment for fragility fractures. A three-stage screening process (titles, abstracts, full text) was conducted by two researchers independently. Participant characteristics, study design, potential correlates examined, analyses, and findings were extracted for studies included in the review. Quality and risk of bias were assessed with the Effective Public Health Practice Project Quality Assessment Tool. The strength of evidence was incorporated into a best evidence synthesis, and meta-analysis was conducted where effect pooling was possible. RESULTS Eleven of 35 eligible studies were categorized as high quality studies. These studies reported that age, higher Cumulative Illness Rating scores, American Society of Anesthesiologists scores > 3, longer length of stay, male sex, cardiovascular disease, low post-operative hemoglobin, kidney disease, dementia and cancer were factors identified at the index admission that were predictive of subsequent re-presentation to hospital. Age was the only predictor for which pooling of effects across studies was possible: pooling was conducted for re-presentation ≤ 30 days (pooled OR, 1.27; 95 % CI, 1.14-1.43) and > 30 days (pooled OR, 1.23; 95 % CI, 1.01-1.50). CONCLUSIONS The best-evidence synthesis, in addition to the meta-analysis, identified a range of factors that may have utility in guiding clinical practice and policy guidelines for targeted interventions to reduce the need for re-presentation to hospital among this frail clinical population. The paucity of studies investigating re-presentations to hospital emergency departments without admission was an important gap in the literature identified in this review. Key limitations were exclusion of non-English language studies and grey literature. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42015019379 .

Abstract
Patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) have suppressed TLR2 expression, function and cytokine production. The aim of this study was to explore the importance of hepatitis B virus (HBV) genotype in innate immune responses and investigate whether Toll-like receptor (TLR) expression/function has potential roles as predictive biomarkers of successful therapy with pegylated interferon (Peg-IFN) therapy of HBeAg seroconversion in HBeAg-positive patients. We showed that as early as 4 weeks after initiation of Peg-IFN, future HBeAg seroconverters had significantly elevated levels of TLR2 expression on monocytes. TLR2-associated IL-6 production at baseline and week 4 of therapy and TLR4 IL-6 production at week 4 were also markedly elevated in HBeAg seroconverters. HBV genotype also influenced treatment response, with genotypes A and B more likely to seroconvert than D. We were able to demonstrate that these differences were due in part to the interaction of the specific HBeAg proteins with TLR pathway adaptor molecules, and these interactions were genotype dependent. HBeAg-mediated modulation of TLR signalling was also observed in Huh7 cells, following stimulation with Pam3Cys. Importantly, the addition of IFN-α to TLR2-stimulated cells cotransfected with an HBeAg expression plasmid reversed HBeAg-mediated suppression of hepatocytes. These findings demonstrate that patients with an activated inflammatory response are much more likely to respond to IFN therapy, with TLR responses showing promise as potential biomarkers of HBeAg seroconversion in this setting. Furthermore, our findings suggest there is differential genotype-specific HBeAg suppression of innate signalling pathways which may account for some of the clinical differences observed across the CHB spectrum.

Abstract
OBJECTIVE The Nintendo Wii Fit integrates virtual gaming with body movement, and may be suitable as an adjunct to conventional physiotherapy following lower limb fractures. This study examined the feasibility and safety of using the Wii Fit as an adjunct to outpatient physiotherapy following lower limb fractures, and reports sample size considerations for an appropriately powered randomised trial. METHODOLOGY Ambulatory patients receiving physiotherapy following a lower limb fracture participated in this study (n=18). All participants received usual care (individual physiotherapy). The first nine participants also used the Wii Fit under the supervision of their treating clinician as an adjunct to usual care. Adverse events, fracture malunion or exacerbation of symptoms were recorded. Pain, balance and patient-reported function were assessed at baseline and discharge from physiotherapy. RESULTS No adverse events were attributed to either the usual care physiotherapy or Wii Fit intervention for any patient. Overall, 15 (83%) participants completed both assessments and interventions as scheduled. For 80% power in a clinical trial, the number of complete datasets required in each group to detect a small, medium or large effect of the Wii Fit at a post-intervention assessment was calculated at 175, 63 and 25, respectively. CONCLUSIONS The Nintendo Wii Fit was safe and feasible as an adjunct to ambulatory physiotherapy in this sample. When considering a likely small effect size and the 17% dropout rate observed in this study, 211 participants would be required in each clinical trial group. A larger effect size or multiple repeated measures design would require fewer participants.

Abstract
BACKGROUND After being discharged from hospital following the acute management of a fragility fracture, older adults may re-present to hospital emergency departments in the post-discharge period. Early re-presentation to hospital, which includes hospital readmissions, and emergency department presentations without admission may be considered undesirable for individuals, hospital institutions and society. The identification of modifiable risk factors for hospital re-representation following initial fracture management may prove useful for informing policy or practice initiatives that seek to minimise the need for older adults to re-present to hospital early after they have been discharged from their initial inpatient care. The purpose of this systematic review is to identify correlates of hospital re-presentation in older patients who have been discharged from hospital following clinical management of fragility fractures. METHODS/DESIGN The review will follow the PRISMA-P reporting guidelines for systematic reviews. Four electronic databases (PubMed, CINAHL, Embase, and Scopus) will be searched. A suite of search terms will identify peer-reviewed articles that have examined the correlates of hospital re-presentation in older adults (mean age of 65 years or older) who have been discharged from hospital following treatment for fragility fractures. The Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies will be used to assess the quality of the studies. The strength of evidence will be assessed through best evidence synthesis. Clinical and methodological heterogeneity across studies is likely to impede meta-analyses. DISCUSSION The best evidence synthesis will outline correlates of hospital re-presentations in this clinical group. This synthesis will take into account potential risks of bias for each study, while permitting inclusion of findings from a range of quantitative study designs. It is anticipated that findings from the review will be useful in identifying potentially modifiable risk factors that have relevance in policy, practice and research priorities to improve the management of patients with fragility fractures.

Abstract
The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 15 countries, and the relative impact of two scenarios was considered: (i) increased treatment efficacy while holding the treated population constant and (ii) increased treatment efficacy and increased annual treated population. Increasing levels of diagnosis and treatment, in combination with improved treatment efficacy, were critical for achieving substantial reductions in disease burden. In most countries, the annual treated population had to increase several fold to achieve the largest reductions in HCV-related morbidity and mortality. This suggests that increased capacity for screening and treatment will be critical in many countries. Birth cohort screening is a helpful tool for maximizing resources. In most of the studied countries, the majority of patients were born between 1945 and 1985.

Abstract
Morbidity and mortality attributable to chronic hepatitis C virus (HCV) infection are increasing in many countries as the infected population ages. Models were developed for 15 countries to quantify and characterize the viremic population, as well as estimate the number of new infections and HCV related deaths from 2013 to 2030. Expert consensus was used to determine current treatment levels and outcomes in each country. In most countries, viremic prevalence has already peaked. In every country studied, prevalence begins to decline before 2030, when current treatment levels were held constant. In contrast, cases of advanced liver disease and liver related deaths will continue to increase through 2030 in most countries. The current treatment paradigm is inadequate if large reductions in HCV related morbidity and mortality are to be achieved.

Abstract
Chronic hepatitis C virus (HCV) infection is a leading cause of liver related morbidity and mortality. In many countries, there is a lack of comprehensive epidemiological data that are crucial in implementing disease control measures as new treatment options become available. Published literature, unpublished data and expert consensus were used to determine key parameters, including prevalence, viremia, genotype and the number of patients diagnosed and treated. In this study of 15 countries, viremic prevalence ranged from 0.13% in the Netherlands to 2.91% in Russia. The largest viremic populations were in India (8 666 000 cases) and Russia (4 162 000 cases). In most countries, males had a higher rate of infections, likely due to higher rates of injection drug use (IDU). Estimates characterizing the infected population are critical to focus screening and treatment efforts as new therapeutic options become available.

Abstract
UNLABELLED As there is currently a lack of consensus on the most appropriate dose and duration of peginterferon alfa-2a (PEG-IFNα-2a) therapy in hepatitis B e antigen (HBeAg)-positive patients, the efficacy and safety of either 24 or 48 weeks' duration and 90 μg/week or 180 μg/week doses were compared. HBeAg-positive patients (n = 544; 34% genotype B, 51% genotype C) were randomized to receive PEG-IFNα-2a (2 × 2 factorial design) for 24 or 48 weeks and at 90 μg/week or 180 μg/week and included in the per-protocol population. The primary efficacy endpoint of the noninferiority study was HBeAg seroconversion 6 months posttreatment. The prespecified odds ratio (OR) noninferiority margin was 1.88 with a one-sided significance level of 0.025. The highest rates of HBeAg seroconversion 6 months posttreatment were in the 180/48 arm (36.2% versus 14.1%-25.8% in the other arms). When the dose and duration arms were pooled, the OR for noninferiority of 24 weeks versus 48 weeks was 2.17 (95% confidence interval [CI] 1.43, 3.31; P = 0.749) and for 90 μg versus 180 μg was 1.79 (95% CI 1.18, 2.72; P = 0.410). As the upper limit of the 95% CI of the ORs were >1.88, 24 weeks were inferior to 48 weeks and 90 μg/week was inferior to 180 μg/week. The highest rates of response in the 180/48 arm were achieved by patients with HBsAg <1,500 IU/mL at Week 12 (58%) or Week 24 (57%), whereas patients with HBsAg >20,000 IU/mL did not respond. Adverse events were typical of those associated with PEG-IFNα-2a. CONCLUSION Compared with lower doses and shorter durations, the licensed PEG-IFNα-2a treatment regimen (180 μg/48 weeks) was the most efficacious and beneficial for HBeAg-positive patients predominantly infected with hepatitis B virus genotypes B or C.

Abstract
X-linked lymphoproliferative (XLP) syndrome is a rare primary immune-deficiency disorder caused by mutations of the SH2D1A or XIAP genes. Males with the disorder are usually in good health until contracting Epstein-Barr virus (EBV) whereupon the majority of patients die from fulminant infectious mononucleosis, lymphoma or hypogammaglobulinaemia. This report describes a female carrier with an XLP phenotype who was retrospectively identified after her grandson died from the disorder. Subsequent genetic testing identified the patient's mother and affected maternal grandmother as XLP carriers. The family's medical records were significant. The proband had lymphoma at ages 2 and 8 and made a full recovery following treatment. Both the maternal grandmother and uncle died of non-Hodgkin's lymphoma. We were concerned that the XLP carrier mother may be predisposed to lymphoma if the normal X chromosome is skewed towards inactivation. The human androgen receptor assay detected random X chromosome inactivation in the carrier mother. EBV was not detected in the lymphoma tissues of the proband and his grandmother, confirming previous findings that EBV is not always associated with lymphoma in XLP. More significantly, our study highlights the importance of identifying XLP in families with a high incidence of lymphoma.

Abstract
The purpose of this study was the economic evaluation of short-duration treatments of chronic hepatitis B (CHB) and longer duration antiviral treatment for up to 5 years. Two 10-health state Markov models were developed for hepatitis B e antigen (HBeAg)-positive and HBeAg-negative CHB patients respectively. The perspective of this economic evaluation was the Singapore healthcare system and CHB patient. The models followed cohorts of HBeAg-positive and HBeAg-negative CHB patients, respectively, over a period of 40 years, by which time the majority of the cohorts would have died if left untreated. Costs and benefits were discounted at 5% per annum. Annual rates of disease progression and the magnitude of treatment effects were obtained from the literature, with a focus on data obtained in Asian patients and meeting the criteria for therapy as described in internationally recognized management guidelines. Short-course therapy with alpha-interferon, or 1-year treatment with pegylated interferon alpha-2a, lamivudine or adefovir had limited impact on disease progression. In contrast, treatment of CHB with antiviral therapy for 5 years substantially decreased the rate of disease progression. Treatment with lamivudine for 1-year is highly cost-effective compared with no treatment of CHB but has limited effect on reducing the rate of disease progression. Compared with 1-year treatment with lamivudine, sequential antiviral therapies for up to 5 years (i.e. lamivudine plus adefovir on emergence of lamivudine resistance or adefovir plus lamivudine on emergence of adefovir resistance) are highly cost-effective by international standards. These conclusions are robust to uncertainties in model inputs and are consistent with the findings of other recently published studies.

Abstract
Intractable liver allograft rejection remains an important cause of graft loss. In this present study, we evaluated the role of oral FK 506 in 30 rejection episodes resistant to conventional cyclosporin-based triple immunosuppression in a series of 28 patients. Rejection was reversed in 11 (91.7%) of 12 patients for intractable acute rejection and in 10 (58.8%) of 17 patients for chronic rejection. A progressive decline in serum bilirubin was observed within 14 days in those successfully salvaged and a serum bilirubin of less than 200 micromol/l at the time of FK 506 conversion in the chronic rejection subgroup was found to be good predictor of response (specificity 100%, sensitivity 60%). New onset diabetes mellitus (29%) and reversible renal impairment (32%) were the commonest adverse events observed. Eleven (52%) of the responding patients successfully discontinued corticosteroid medication and are currently on FK 506 monotherapy. FK 506 therapy has a significant impact in the control of both intractable acute and chronic allograft rejection with an acceptable toxicity profile.

Abstract
BACKGROUND Covalent attachment of a 40-kd branched-chain polyethylene glycol moiety to interferon alfa-2a results in a compound (peginterferon alfa-2a) that has sustained absorption, a slower rate of clearance, and a longer half-life than unmodified interferon alfa-2a. We compared the clinical effects of a regimen of peginterferon alfa-2a with those of a regimen of interferon alfa-2a in the initial treatment of patients with chronic hepatitis C. METHODS We randomly assigned 531 patients with chronic hepatitis C to receive either 180 microg of peginterferon alfa-2a subcutaneously once per week for 48 weeks (267 patients) or 6 million units of interferon alfa-2a subcutaneously three times per week for 12 weeks, followed by 3 million units three times per week for 36 weeks (264 patients). All the patients were assessed at week 72 for a sustained virologic response, defined as an undetectable level of hepatitis C virus RNA (<100 copies per milliliter). RESULTS In the peginterferon group, 223 of the 267 patients completed treatment and 206 completed follow-up. In the interferon group, 161 of the 264 patients completed treatment and 154 completed follow-up. In an intention-to-treat analysis in which patients who missed the examination at the end of treatment or follow-up were considered not to have had a response at that point, peginterferon alfa-2a was associated with a higher rate of virologic response than was interferon alfa-2a at week 48 (69 percent vs. 28 percent, P=0.001) and at week 72 (39 percent vs. 19 percent, P=0.001). Sustained normalization of serum alanine aminotransferase concentrations at week 72 was also more common in the peginterferon group than in the interferon group (45 percent vs. 25 percent, P=0.001). The two groups were similar with respect to the frequency and severity of adverse events, which were typical of those associated with interferon alfa. CONCLUSIONS In patients with chronic hepatitis C, a regimen of peginterferon alfa-2a given once weekly is more effective than a regimen of interferon alfa-2a given three times weekly.

Abstract
AIM Previous studies have identified high prevalence rates of hepatitis B infection in New Zealand Maori, Pacific Island and Asian populations within New Zealand. However, the true impact of chronic hepatitis B virus (HBV) infection on health resources has not been evaluated. This study was designed to determine the incidence of serious sequelae of chronic HBV infection in a high prevalence community. METHODS All patients treated for HBV-related conditions at Middlemore Hospital from January 1995 to January 1997 were identified through discharge coding and laboratory records. Demographic characteristics and laboratory results, including liver function tests, hepatitis serology and liver histology were recorded. Number of admissions, average length of stay and survival were calculated from Casemix data. RESULTS During the study period, 215 patients were referred for management of hepatitis B infection, of whom 179 had persistently elevated aminotransferases. Forty six percent of patients were hepatitis B 'e' antigen (HBeAg) negative, and 21% of these had delta co-infection (all Samoan). Liver biopsy was performed in 87 patients with raised aminotransferases. No features of chronic hepatitis were found in 5%, mild chronic hepatitis in 30%, moderate to severe chronic hepatitis in 44% and cirrhosis in 22%. Fifty five patients were admitted to hospital during the two year period with an HBV-related diagnosis, with an average length of stay of 12.2 days compared to 4.9 days for all other medical and surgical admissions during this period (p < 0.001). Twenty eight of the 55 subsequently died, 20 from hepatocellular carcinoma. CONCLUSIONS Chronic hepatitis B infection is associated with significant morbidity and mortality in Maori, Pacific Islanders and Asians living in South Auckland. Screening of these high risk populations with vaccination of noninfected individuals should reduce the incidence of these serious sequelae and eventually lead to eradication of HBV.

Abstract
BACKGROUND Cytomegalovirus (CMV) disease is a frequent cause of serious morbidity after solid-organ transplantation. The prophylactic regimens used to prevent CMV infection and disease have shown limited benefit in seronegative recipients. We studied the safety and efficacy of oral ganciclovir in the prevention of CMV disease following orthotopic liver transplantation. METHODS Between December, 1993, and April, 1995, 304 liver-transplant recipients were randomised to receive oral ganciclovir 1000 mg or matching placebo three times a day. Seronegative recipients of seronegative livers were excluded. Study drug was administered as soon as the patient was able to take medication by mouth (no later than day 10) until the 98th day after transplantation. Patients were assessed at specified times throughout the first 6 months after surgery for evidence of CMV infection, CMV disease, rejection, opportunistic infections, and possible drug toxicity. FINDINGS The Kaplan-Meier estimate of the 6-month incidence of CMV disease was 29 (18.9%) of 154 in the placebo group, compared with seven (4.8%) of 150 in the ganciclovir group (p < 0.001). In the high-risk group of seronegative recipients (R-) of seropositive livers (D+), incidence of CMV disease was 11 (44.0%) of 25 in the placebo group, three (14.8%) of 21 in the ganciclovir group (p = 0.02). Significant benefit was also observed in those receiving antibodies to lymphocytes, where the incidence of CMV disease was 12 (32.9%) of 37 in the placebo group and two (4.6%) of 44 in the ganciclovir group (p = 0.002). Oral ganciclovir reduced the incidence of CMV infection (placebo 79 [51.5%] of 154; ganciclovir 37 [24.5%] of 150; p < 0.001) and also reduced symptomatic herpes-simplex infections (Kaplan-Meier estimates: placebo 36 [23.5%] of 154; ganciclovir five [3.5%] of 150; p < 0.001). INTERPRETATION Oral ganciclovir is a safe and effective method for the prevention of CMV disease after orthotopic liver transplantation.

Abstract
BACKGROUND/AIMS Post-transplant lymphoproliferative disorder is a well-documented complication with an incidence ranging from 2 to 10%, depending on the organ transplanted. Yet despite our increased understanding of the pathophysiology of this disease and the various treatments available, the mortality remains high at 60-80%. We present the clinical and histological features of ten adult liver transplant recipients with post-transplant lymphoproliferative disorder presenting over a 15-year period and review the therapeutic options. METHODS CD20/CD45RO immunostaining was used for T/B-cell markers; polymerase chain reaction and in-situ hybridisation for Epstein-Barr virus genome detection; kappa/lambda immunostaining and gene rearrangement analysis for clonality. RESULTS There were six females and four males (age range 24-56) with onset of post-transplant lymphoproliferative disorder-symptoms ranging from 3 to 72 months post transplant. Sites of post-transplant lymphoproliferative disorder included liver (n=4), lymph nodes (n=5), bone marrow (n=2), lungs (n=2), kidneys (n=2), brain, ovaries,: and pancreas (n=1). All lesions were classified as high-grade lymphoma, of B-cell lineage (9 tested); Epstein-Barr virus genome was detected in 7/10 cases. Three tumours were monoclonal; four were polyclonal and three undetermined. Treatment included immunosuppression reduction, antiviral therapy with acyclovir and/or chemotherapy (CHOP or VAPEC-B). Survival times for those patients not treated with chemotherapy were from 9 days to 30 months, whereas those receiving chemotherapy had remission times of 4 to 48 months. CONCLUSIONS Longer-term remissions can be achieved in patients treated with systemic chemotherapy, although not without morbidity. Clonality assessment is important but treatment decisions should be based primarily on clinical features of progression, as polyclonal tumours can behave as aggressively as monoclonal tumours.

Abstract
A prospective randomised study of end-to-end bile duct reconstruction with or without T-tube drainage during orthotopic liver transplantation (OLT) was undertaken in 60 patients well matched for age, sex, aetiology of liver disease, operative blood loss, cold ischaemic time, preoperative serum bilirubin level and Child-Pugh score. Significant biliary complications in the T tube group occurred in five patients and included bile duct stricture (n = 2), bile leak/peritonitis (n = 1) and cholangitis (n = 2). Bile duct strictures occurred in six patients in the no T tube group (P > 0.05, NS). Hepatic artery stenosis was identified in one patient from each group in association with a biliary stricture. Biliary complications in both groups were associated with a prolonged graft cold ischaemic time (P < 0.01). As no significant difference was noted in the number of early and late biliary complications between the two groups, the routine use of a T tube has been discontinued.

Abstract
In this clinicopathological study, we have examined the prevalence of biochemical and histological graft abnormalities in 116 patients who have lived for longer than five years since orthotopic liver transplantation (mean, 8.4 years [range, 5.2-19.5 years]). In each patient, the protocol biopsy was carried out in addition to full clinical, biochemical, and immunological evaluation. The renal function was preserved in most patients (mean creatinine, 86 micromol/L [0.95 mg%]) with only 35% showing any degree of impairment, and only one patient with pretransplant renal failure required dialysis. Forty one (35%) of the patients had normal biochemical liver function tests (LFTs); 19 of these patients had histologic abnormalities. Of the remaining 75 patients with abnormal LFTs, 65 were found to have histological abnormalities on liver biopsy. Some of the 84 patients with an abnormal histology had more than one finding but were placed into 6 categories according to the main change as follows: chronic hepatitis in 27; primary biliary cirrhosis-like changes in 8; cholangitis in 15; structural anomalies in 26; chronic rejection in 2; mild acute cellular rejection in 1; and miscellaneous in 5. The recurrence of B, C, or autoimmune hepatitis accounted for 14 cases of chronic hepatitis, whereas, in 13 cases, no cause could be detected. The latter cases included 8 patients who had liver transplants for primary biliary cirrhosis (PBC), leaving suboptimally treated rejection or disease recurrence as possible causes. Characteristic histological features of PBC were observed in 8 additional cases that had liver transplantations for this disease. Of the 26 cases with structural anomalies, various types of occlusive vasculopathy were detected during pre- or posttransplantation in 12 cases. All but one of these were maintained on azathioprine, the only possible etiological factor in the 14 other cases, 5 of whom showed stabilization or clinical and histological improvement following withdrawal of the drug. De-novo malignancy was seen in 3.4% of cases, causing mortality in only one patient to date. This study demonstrates an unexpectedly high prevalence of histological abnormalities that is found often in the presence of normal biochemical liver-function in liver grafts of long-term survivors. Although graft loss at this time is rare, protocol liver biopsies at 5 years, and thereafter at 2-year intervals, may allow for earlier beneficial therapeutic intervention.

Abstract
BACKGROUND Experience of liver transplantation in haemophiliacs with end stage hepatitis C liver disease is limited and particularly difficult questions are raised when there is also HIV infection. AIMS This is the first report in Great Britain to describe the operative replacement therapy and initial outcome in four haemophiliacs with end stage HCV cirrhosis. PATIENTS Two patients had factor VIII, one had factor IX, and one had factor X deficiency. One patient had also contracted HIV infection from factor replacement but had no AIDS defining illnesses. METHODS Intraoperatively patients were given either factor VIII infusions, factor IX bolus, or fresh frozen plasma, according to formulae devised to calculate exact clotting factor requirements. Baseline preoperative coagulation studies included prothrombin time, activated partial thromboplastin time, fibrinogen concentrations, and factor VIII, IX, and X concentrations. Factor concentrations were then assayed at 12, 24, 48, and 72 hours postoperatively. RESULTS Postoperatively all patients had coagulation factor concentrations sustained within the normal ranges by 72 hours unsupported (137, 125, 95, 104 IU/dl), representing de novo synthesis by the graft. Transfusion requirements during the operative and immediate post-transplant period were no greater than those of patients without clotting disorders. Two patients had episodes of bleeding postoperatively, one of which was fatal, occurring at the site of a previous untreated subdural bleed. In both instances the bleeding occurred in the presence of normal concentrations of clotting factor. The remaining three patients are at 6, 6, and 12 months post-transplant and remarkably improved clinically with sustained factor concentrations. One patient has evidence of graft dysfunction from HCV recurrence and all have evidence of recurrent viraemia with HCV on polymerase chain reaction studies. CONCLUSIONS Orthotopic liver transplantation should be considered in haemophiliac patients with end stage liver disease from hepatitis C infection with or without concomitant HIV infection. Their clinical condition is likely to be greatly improved by orthotopic liver transplantation and the haemophilia cured with only a small risk of severe graft dysfunction from recurrent HCV infection.
