Abstract
STATEMENT OF PROBLEM To fully maximize the potential of dual-polymerizing resin cements, a thorough understanding of how the light- and chemical-polymerizing components interact in a resin system is required. Disorder in the polymerization process between the two components may hurt one of the components versus the other, affecting the overall properties and performance of the resin cements. PURPOSE Evaluate photo-polymerization delay time on dentin shear-bond strength and Vickers microhardness of dual-polymerizing resin cements. METHODS AND MATERIALS Shear bond strength (SBS) of self-adhesive (RelyX Unicem 2, 3M ESPE) and adhesive (RelyX Ultimate, 3M ESPE) dual-polymerizing resin cements were evaluated. Dentin specimens (n=80) were prepared for the SBS test according to ISO standard 29022:2013. Teeth were randomly allocated into eight groups based on the type of cement, and photo-polymerization delay times (0, 2, 5, and 10 minutes). Vickers microhardness test (HV) was performed following ASTM E384-17 (n=32) prepared based on cement type and photo-polymerization delay times; specimens were tested after 24 hours of storage. Statistical analysis was performed using two-way ANOVA to determine the individual and combined effects of resin cement type and photo-polymerization delay time on SBS and HV. RESULTS Resin cement and photo-polymerization delay times for the adhesive cement at 0- and 2-minute pairings had significantly higher SBS means than all other combinations (p<0.0001). Resin cement type was also statistically significant (p<0.0001). Resin cement type and photo-polymerization delay times were not significant (p=0.3550) for HV. CONCLUSIONS Photo-polymerization delay time affected dentin SBS with higher bond strength when photo-polymerization delay time was performed between 2 and 5 minutes with a self-adhesive resin cement, and between 0 and 2 minutes with an adhesive resin cement. Delaying photo-polymerization time to 10 minutes led to inferior dentin SBS and HV for both self-adhesive and adhesive dual-polymerizing resin cements.

Abstract
RAC1 activity is critical for intestinal homeostasis, and is required for hyperproliferation driven by loss of the tumour suppressor gene Apc in the murine intestine. To avoid the impact of direct targeting upon homeostasis, we reasoned that indirect targeting of RAC1 via RAC-GEFs might be effective. Transcriptional profiling of Apc deficient intestinal tissue identified Vav3 and Tiam1 as key targets. Deletion of these indicated that while TIAM1 deficiency could suppress Apc-driven hyperproliferation, it had no impact upon tumourigenesis, while VAV3 deficiency had no effect. Intriguingly, deletion of either gene resulted in upregulation of Vav2, with subsequent targeting of all three (Vav2-/- Vav3-/- Tiam1-/-), profoundly suppressing hyperproliferation, tumourigenesis and RAC1 activity, without impacting normal homeostasis. Critically, the observed RAC-GEF dependency was negated by oncogenic KRAS mutation. Together, these data demonstrate that while targeting RAC-GEF molecules may have therapeutic impact at early stages, this benefit may be lost in late stage disease.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
The uremic syndrome is a complex mixture of organ dysfunctions, which is attributed to the retention of a myriad of compounds that under normal condition are excreted by the healthy kidneys (uremic toxins). In the area of identification and characterization of uremic toxins and in the knowledge of their pathophysiologic importance, major steps forward have been made during recent years. The present article is a review of several of these steps, especially in the area of information about the compounds that could play a role in the development of cardiovascular complications. It is written by those members of the Uremic Toxins Group, which has been created by the European Society for Artificial Organs (ESAO). Each of the 16 authors has written a state of the art in his/her major area of interest.

Abstract
Members of the Acute Dialysis Quality Initiative (ADQI) participated in a 3-day conference in Vicenza in May 2007 to evaluate the available literature on this topic and draft consensus recommendations for research studies in this area. This report summarizes the available evidence and describes the key questions that will need to be addressed with the goal of standardizing the care of patients with cardiac surgery-associated acute kidney injury (CSA-AKI) and improving outcomes.

Abstract
Marine Protected Areas (MPAs), marine areas in which human activities are restricted, are implemented worldwide to protect the marine environment. However, with a large proportion of these MPAs being no more than paper parks, it is important to be able to evaluate MPA success, determined by improvements to biophysical, socio-economic and governance conditions. In this study a systematic literature review was conducted to determine the most frequently used indicators of MPA success. These were then applied to a case study to demonstrate how success can be evaluated. The fifteen most frequently used indicators included species abundance, level of stakeholder participation and the existence of a decision-making and management body. Using the indicator framework with a traffic light system, we demonstrate how an MPA can be evaluated in terms of how well it performs against the indicators using secondary data from the literature. The framework can be used flexibly. For example, where no MPA data currently exist, the framework can be populated by qualitative data provided by local stakeholder knowledge. This system provides a cost-effective and straightforward method for managers and decision-makers to determine the level of success of any MPA and identify areas of weakness. However, given the variety of motivations for MPA establishment, this success needs to be determined in the context of the original management objectives of the MPA with greater weighting being placed on those objectives where appropriate.

Abstract
This study confirmed that observations of blue-green colouration in plasma fractions of the ballan wrasse Labrus bergylta were caused by the linear tetra-pyrrole biliverdin and that the molecule was of the physiologically relevant IXα isomer. Accumulation appears driven by chromogenic association with an unknown protein moiety which precludes enzymatic reduction and would suggest active management. It was demonstrated that the pigment did not fluctuate relative to ontogeny, or indeed binary gender in the species of interest, but mobilisation and depletion in the subset of individuals undergoing sex change at the time of study supports a potential association with gender inversion processes. It is of note that although biliverdin does have some effect on external colouration, the evidence is indicative that crypsis is a supplementary function thus other factors must be considered.

Abstract
BACKGROUND AND PURPOSE Intracranial hemorrhage is the most dreaded complication of neurothrombectomy therapy for acute ischemic stroke. The determinants of intracranial hemorrhage and its impact on clinical course remain incompletely delineated. The purpose of this study is to further investigate the clinical and procedural factors leading to intracranial hemorrhage and to define the clinical impact of different hemorrhagic subtypes. MATERIALS AND METHODS We analyzed data prospectively collected in the Solitaire FR With Intention for Thrombectomy randomized clinical trial. A multivariable logistic regression model was used to identify independent clinical, imaging, and procedural predictors of any intracranial hemorrhage and of 7 intracranial hemorrhage subtypes. Univariate analysis was used to determine the impact of each of the intracranial hemorrhage subtypes on clinical outcome. RESULTS Among the 144 enrolled patients, any radiologic intracranial hemorrhage (21.3% versus 38.2%, P = .035), symptomatic intracranial hemorrhage (1.1% versus 10.9%, P = .012), and subarachnoid hemorrhage (2.2% versus 12.7%, P = .027) occurred less frequently in the Solitaire FR than in the Merci retriever arms. The most common independent determinant of hemorrhage occurrence was rescue therapy with intra-arterial rtPA, which was associated with any intracranial hemorrhage and 4 subtypes and tended to be used more frequently in the Merci group (10.9% versus 3.4%; P = .09). Among the hemorrhage subtypes, basal ganglionic hemorrhage had the strongest impact on good clinical outcome at 90 days (OR, 0.30; P = .025) and was associated with higher reperfusion, prolonged time to treatment, and rescue therapy with intra-arterial rtPA. CONCLUSIONS Intracranial hemorrhage, especially subarachnoid and symptomatic intracerebral hemorrhage, occurs less frequently with the Solitaire FR than the Merci retriever, in part due to less frequent use of rescue therapy with intra-arterial rtPA. Basal ganglionic hemorrhage strongly affects clinical outcome and is distinctively related to late reperfusion.

Abstract
BACKGROUND The primary objective of this study was to compare the effects of pomegranate juice on PSA doubling times (PSADT) in subjects with rising PSA levels after primary therapy for prostate cancer. METHODS Double-blind, placebo-controlled multi-institutional study, evaluated the effects of pomegranate liquid extract on serum PSA levels. The primary end point of this study was change in serum PSADT. Additional secondary and exploratory objectives were to evaluate the safety of pomegranate juice and to determine the interaction of manganese superoxide dismutase (MnSOD) AA genotype and pomegranate treatment on PSADT. RESULTS One-hundred eighty-three eligible subjects were randomly assigned to the active and placebo groups with a ratio of 2:1 (extract N=102; placebo N=64; juice N=17). The majority of adverse events were of moderate or mild grade. Median PSADT increased from 11.1 months at baseline to 15.6 months in the placebo group (P<0.001) compared with an increase from 12.9 months at baseline to 14.5 months in the extract group (P=0.13) and an increase from 12.7 at baseline to 20.3 in the juice group (P=0.004). However, none of these changes were statistically significant between the three groups (P>0.05). Placebo AA patients experienced a 1.8 month change in median PSADT from 10.9 months at baseline to 12.7 months (P=0.22), while extract patients experienced a 12 month change in median PSADT from 13.6 at baseline to 25.6 months (P=0.03). CONCLUSIONS Compared with placebo, pomegranate extract did not significantly prolong PSADT in prostate cancer patients with rising PSA after primary therapy. A significant prolongation in PSADT was observed in both the treatment and placebo arms. Men with the MnSOD AA genotype may represent a group that is more sensitive to the antiproliferative effects of pomegranate on PSADT; however, this finding requires prospective hypothesis testing and validation.

Abstract
Poaching of elephants is now occurring at rates that threaten African populations with extinction. Identifying the number and location of Africa's major poaching hotspots may assist efforts to end poaching and facilitate recovery of elephant populations. We genetically assign origin to 28 large ivory seizures (≥0.5 metric tons) made between 1996 and 2014, also testing assignment accuracy. Results suggest that the major poaching hotspots in Africa may be currently concentrated in as few as two areas. Increasing law enforcement in these two hotspots could help curtail future elephant losses across Africa and disrupt this organized transnational crime.

Abstract
RATIONALE Self-expanding stent retrievers are a promising new device class designed for rapid flow restoration in acute cerebral ischaemia. The SOLITAIRE™ Flow Restoration device (SOLITAIRE) has shown high rates of recanalization in preclinical models and in uncontrolled clinical series. AIMS (1) To demonstrate non-inferiority of SOLITAIRE compared with a legally marketed device, the MERCI Retrieval System®; (2) To demonstrate safety, feasibility, and efficacy of SOLITAIRE in subjects requiring mechanical thrombectomy diagnosed with acute ischaemic stroke. DESIGN : Multicenter, randomized, prospective, controlled trial with blinded primary end-point ascertainment. STUDY PROCEDURES Key entry criteria include: age 22-85; National Institute of Health Stroke Scale (NIHSS) ≥8 and <30; clinical and imaging findings consistent with acute ischaemic stroke; patient ineligible or failed intravenous tissue plasminogen activator; accessible occlusion in M1 or M2 middle cerebral artery, internal carotid artery, basilar artery, or vertebral artery; and patient able to be treated within 8 h of onset. Sites first participate in a roll-in phase, treating two patients with the SOLITAIRE device, before proceeding to the randomized phase. In patients unresponsive to the initially assigned therapy, after the angiographic component of the primary end-point is ascertained (reperfusion with the initial assigned device), rescue therapy with other reperfusion techniques is permitted. OUTCOMES The primary efficacy end-point is successful recanalization with the assigned study device (no use of rescue therapy) and with no symptomatic intracranial haemorrhage. Successful recanalization is defined as achieving Thrombolysis In Myocardial Ischemia 2 or 3 flow in all treatable vessels. The primary safety end-point is the incidence of device-related and procedure-related serious adverse events. A major secondary efficacy end-point is time to achieve initial recanalization. Additional secondary end-points include clinical outcomes at 90 days and radiologic haemorrhagic transformation.

Abstract
BACKGROUND Clinical trials of stroke therapy have been hampered by slow rates of enrolment. PURPOSE Our purpose is to validate a previously developed model for accelerating enrolment in clinical trials by replicating it at new locations. The model employs coordinators who travel from a host institution to enrol participants from a network of participating hospitals. Active surveillance assures identification of all eligible patients. METHODS Among 70 U.S. investigators participating in National Institutes of Health-funded trial of stroke prevention, five investigators were invited to develop local identification and outreach networks (LIONs). Each LION comprised a LION coordinating centre servicing multiple hospitals. Hospitals provided names of patients with stroke or transient ischaemic attack to researchers at the LION coordinating centre who initiated contact; patients were offered home visits for consent and randomization. Outcomes were feasibility, enrolment, data quality, and cost. RESULTS Five LIONs varied in size from two to eight hospitals. All 24 hospitals we approached agreed to participate. The average monthly rate of enrolment at the research sites increased from 1.4 participants to 3.5 after expanding from a single institution model to the LION format (mean change = 2.1, range 0.9-3.7). Monthly performance improved over time. Data quality was similar for LIONs and non-LION sites, except for drug adherence which was lower at LIONs. The average cost to randomize and follow one participant during the study interval was 2.4 times the cost under the per-patient, cost-reimbursement strategy at non-LION sites. The cost ratio declined from 3.4 in year one to 1.8 in year two. LIMITATIONS The LION strategy requires unprecedented collaboration and trust among institutions. Applicability beyond stroke requires confirmation. CONCLUSION LIONs are a practical, reproducible method to increase enrolment in trial research. Twelve months were required for the average site to reach its potential. The per-participant cost at LIONs was higher than conventional sites but declined over time.

Abstract
OBJECTIVE To test the feasibility and efficacy of an approach that foregoes the routine use of ultrasound for the determination of eligibility for medical termination of pregnancy. DESIGN Prospective trial. SETTING Ten termination of pregnancy clinics in the USA. POPULATION A total of 4484 women seeking termination of pregnancy with mifepristone-misoprostol. METHODS Women provided estimates of the date of their last menstrual period and underwent pelvic bimanual and ultrasound examinations. We compared estimates of gestational age using these three methods. MAIN OUTCOME MEASURE Proportion of women of ≤9 weeks' gestation by woman or provider estimate, but >9 weeks' gestation by ultrasound. RESULTS The reliance on women's report of their last menstrual period together with physical examination to determine their eligibility for termination of pregnancy with mifepristone-misoprostol would result in few women (63/4008 or 1.6%) accepted for treatment outside the current limits of standard mifepristone-misoprostol regimens used for early termination of pregnancy (i.e. ≤63 days' gestation on ultrasound). CONCLUSIONS Last menstrual period and physical examination alone, without the routine use of ultrasound, are highly effective for the determination of women's eligibility for early termination of pregnancy with mifepristone-misoprostol.

Abstract
BACKGROUND QT dispersion (QTd) measurement during treadmill stress testing has been to shown to improve the accuracy of exercise electrocardiogram (ECG) in the detection of significant coronary artery disease (CAD). HYPOTHESIS The aim of this study was to determine whether adenosine-induced changes in QTd could predict significant CAD and to assess its efficacy as a diagnostic index in patients undergoing adenosine stress test. METHODS QT interval measurements were made in 57 consecutive patients undergoing adenosine sestamibi stress test. Patients with an abnormal stress test underwent coronary angiography. Patients with significant disease by coronary angiography (> 70% stenosis) were classified as having CAD (Group 1), and those with normal stress images and/or normal coronaries by angiography were classified as having no CAD (Group 2). RESULTS QT dispersion increased from 28.2 +/- 4.5 to 43.8 +/- 4.5 ms with a delta QTd of 15.53 +/- 3.68 in Group 1 (p = 0.001) and from 28.4 +/- 2.6 to 34.8 +/- 2.8 ms with a delta QTd of 6.58 +/- 2.21 ms in Group 2 (p = 0.006). Patients in Group 1 had a significantly higher increase in QTd (delta QTd) than the patients in Group 2 (p < 0.03). Addition of delta QTd (> 10 ms) to the ST depression during adenosine infusion would increase the sensitivity of the ECG from 23 to 65% and decrease the specificity from 91 to 70% for diagnosis of significant CAD. CONCLUSIONS delta QTd is significantly more prolonged in patients with CAD during adenosine infusion. It increases the sensitivity of the stress ECG in diagnosis of CAD during adenosine infusion when used as an adjuvant index.

Abstract
Implantable RF-coils have enabled sub-mm resolution magnetic resonance images (MRI) of deep structures. Scaling down the size of RF coils has similarly provided a gain in signal-to-noise ratio in nuclear-magnetic-resonance spectroscopy. By combining both approaches we designed, fabricated, and imaged with an implantable microcoil catheter. While typical implantable catheters use a transverse magnetization, the axial magnetization of the microcoil provides improved sensitivity and allows visualization of the tissue beyond the distal end of the catheter. The microcoil catheter was designed with a diameter of 1 mm for future integration with intracranial devices, and for intraductal use in breast oncology. We modified the NMR-microcoil design to allow implantation of the RF coil, by winding the microcoil on medical-grade silicone tubing and incorporating leads on the catheter to connect circuit components. In order to achieve proper turn spacing, we coated copper wire with 25 microm of biocompatible polymer (Parylene C). Tuning and matching circuitry insured that the impedance of the RF coil was approximately 50 ohm at the operating frequency for 3-T proton MR applications. A duplexer was used to enable use of the microcoil catheter as a transceiver. Experimental verification of the coil design was achieved through ex vivo imaging of neural tissue. As expected, the microcoil catheter provided microscale images with 20-microm in-plane-resolution and 170-microm-thick slices. While 3-T MRI typically provides 1 to 30 voxels per-cubic-millimeter, in this paper we report that the MRI microcoil can provide hundreds, and even thousands of voxels in the same volume.

Abstract
OBJECTIVE To investigate the safety, efficacy, and acceptability of misoprostol versus manual vacuum aspiration (MVA) for treatment of incomplete abortion. DESIGN A prospective open-label randomised trial. SETTING Kagera Regional Hospital, Bukoba, Tanzania. SAMPLE Three hundred women with a clinical diagnosis of incomplete abortion and a uterine size <12 weeks. METHODS A total of 150 women were randomised to either a single dose of 600 micrograms of oral misoprostol or MVA. If abortion was clinically complete at 7-day follow up, the woman was released from the study. If it was still incomplete, the woman was offered the choice of an additional 1-week follow up or immediate MVA. Cases still incomplete after a further week were offered MVA. MAIN OUTCOME MEASURES Incidence of successful abortion (success defined as no secondary surgical intervention provided), incidence of adverse effects, patient satisfaction. RESULTS Success was very high in both arms (misoprostol: 99%; MVA: 100%; difference not significant). Most adverse effects were higher in the misoprostol arm, although the mean pain score was higher in the MVA arm (3.0 versus 3.5; P < 0.001). More women were very satisfied with misoprostol (75%) than with MVA (55%, P = 0.001), and a higher proportion of women in the misoprostol arm said that they would recommend the treatment to a friend (95% versus 75%, P < 0.001). CONCLUSION Misoprostol is as effective as MVA at treating incomplete abortion at uterine size of <12 weeks. The acceptability of misoprostol appears higher. Given the many practical advantages of misoprostol over MVA in low-resource settings, misoprostol should be more widely available for treatment of incomplete abortion in the developing world.

Abstract
OBJECTIVES This report reviews the clinical effectiveness and cost-effectiveness of adalimumab, etanercept and infliximab, agents that inhibit tumour necrosis factor-alpha (TNF-alpha), when used in the treatment of rheumatoid arthritis (RA) in adults. DATA SOURCES Electronic databases were searched up to February 2005. REVIEW METHODS Systematic reviews of the literature on effectiveness and cost-effectiveness were undertaken and industry submissions to the National Institute for Health and Clinical Excellence (NICE) were reviewed. Meta-analyses of effectiveness data were also undertaken for each agent. The Birmingham Rheumatoid Arthritis Model (BRAM), a simulation model, was further developed and used to produce an incremental cost-effectiveness analysis. RESULTS Twenty-nine randomised controlled trials (RCTs), most of high quality, were included. The only head-to-head comparisons were against methotrexate. For patients with short disease duration (<or=3 years) who were naïve to methotrexate, adalimumab was marginally less and etanercept was marginally more effective than methotrexate in reducing symptoms of RA. Etanercept was better tolerated than methotrexate. Both adalimumab and etanercept were more effective than methotrexate in slowing radiographic joint damage. Etanercept was also marginally more effective and better tolerated than methotrexate in patients with longer disease durations who had not failed methotrexate treatment. Infliximab is only licensed for use with methotrexate. All three agents, either alone (where so licensed) or in combination with ongoing disease-modifying antirheumatic drugs (DMARDs), were effective in reducing the symptoms and signs of RA in patients with established disease. At the licensed dose, the numbers needed to treat (NNTs) (95% CI) required to produce an American College for Rheumatology (ACR) response compared with placebo were: ACR20: adalimumab 3.6 (3.1 to 4.2), etanercept 2.1 (1.9 to 2.4), infliximab 3.2 (2.7 to 4.0); ACR50: adalimumab 4.2 (3.7 to 5.0), etanercept 3.1 (2.7 to 3.6), infliximab 5.0 (3.8 to 6.7); and ACR70: adalimumab 7.7 (5.9 to 11.1), etanercept 7.7 (6.3 to 10.0), infliximab 11.1 (7.7 to 20.0). In patients who were naïve to methotrexate, or who had not previously failed methotrexate treatment, a TNF inhibitor combined with methotrexate was significantly more effective than methotrexate alone. Infliximab combined with methotrexate had an increased risk of serious infections. All ten published economic evaluations met standard criteria for quality, but the incremental cost-effectiveness ratios (ICERs) ranged from being within established thresholds to being very high because of varying assumptions and parameters. All three sponsors who submitted economic models made assumptions favourable to their product. BRAM incorporates improvements in quality of life and mortality, but assumes no effect of TNF inhibitors on joint replacement. For use in accordance with current NICE guidance as the third DMARD in a sequence of DMARDs, the base-case ICER was around pound30,000 per quality-adjusted life-year (QALY) in early RA and pound50,000 per QALY in late RA. Sensitivity analyses showed that the results were sensitive to the estimates of Health Assessment Questionnaire (HAQ) progression while on TNF inhibitors and the effectiveness of DMARDs, but not to changes in mortality ratios per unit HAQ. TNF inhibitors are most cost-effective when used last. The ICER for etanercept used last is pound24,000 per QALY, substantially lower than for adalimumab ( pound30,000 per QALY) or infliximab ( pound38,000 per QALY). First line use as monotherapy generates ICERs around pound50,000 per QALY for adalimumab and etanercept. Using the combination of methotrexate and a TNF inhibitor as first line treatment generates much higher ICERs, as it precludes subsequent use of methotrexate, which is cheap. The ICERs for sequential use are of the same order as using the TNF inhibitor alone. CONCLUSIONS Adalimumab, etanercept and infliximab are effective treatments compared with placebo for RA patients who are not well controlled by conventional DMARDs, improving control of symptoms, improving physical function, and slowing radiographic changes in joints. The combination of a TNF inhibitor with methotrexate was more effective than methotrexate alone in early RA, although the clinical relevance of this additional benefit is yet to be established, particularly in view of the well-established effectiveness of MTX alone. An increased risk of serious infection cannot be ruled out for the combination of methotrexate with adalimumab or infliximab. The results of the economic evaluation based on BRAM are consistent with the observations from the review of clinical effectiveness, including the ranking of treatments. TNF inhibitors are most cost-effective when used as last active therapy. In this analysis, other things being equal, etanercept may be the TNF inhibitor of choice, although this may also depend on patient preference as to route of administration. The next most cost-effective use of TNF inhibitors is third line, as recommended in the 2002 NICE guidance. Direct comparative RCTs of TNF inhibitors against each other and against other DMARDs, and sequential use in patients who have failed a previous TNF inhibitor, are needed. Longer term studies of the quality of life in patients with RA and the impact of DMARDs on this are needed, as are longer studies that directly assess effects on joint replacement, other morbidity and mortality.

Abstract
BACKGROUND Post-infectious irritable bowel syndrome is a common clinical phenomenon of uncertain aetiology. AIM To test the association between intestinal permeability and irritable bowel syndrome symptoms 2 years after a large waterborne outbreak of bacterial gastroenteritis. METHODS Consecutive adults with Rome I irritable bowel syndrome and controls without irritable bowel syndrome attending a community clinic were enrolled. Intestinal permeability was measured as the ratio of fractional urinary excretions of lactulose and mannitol, and compared among cases vs. controls and predictors of abnormal intestinal permeability were assessed. RESULTS A total of 218 subjects (132 irritable bowel syndrome cases and 86 non-irritable bowel syndrome controls) completed the study protocol. About 27 (12%) had been diagnosed with the irritable bowel syndrome before the outbreak and 115 (53%) had been ill during the outbreak. Lactulose-mannitol ratios were increased among cases vs. controls (Mann-Whitney mean rank 118.8 vs. 95.3, P = 0.007), and cases were more likely to have a ratio >0.020 (P = 0.007). Among cases, those with increased intestinal permeability were more likely to report increased stool frequency. Both irritable bowel syndrome symptoms and male gender, but not diarrhoeal illness during the outbreak, were significant predictors of abnormal permeability. CONCLUSIONS Irritable bowel syndrome symptoms are associated with a subtle increase in intestinal permeability irrespective of prior gastroenteritis. This may improve understanding of the aetiology of both sporadic and post-infectious irritable bowel syndrome.

Abstract
ISSUE Inadequate pain management is a serious public health problem that affects a wide cross-section of Americans. Patients are often denied sufficient medication, because physicians lack training and fear scrutiny from federal and state regulatory agencies. In addition, even the state-financed system of care, Medicaid, has been increasingly denying payment for the best treatment for pain management. These factors are complicated by physician bias about various subgroups and poor physician-patient communication. Comprehensive patient assessment plays a crucial role in determining appropriate treatment and identifying potential abuse problems. Physicians must routinely document medications analgesic effects and screen for potential ill effects and drug abuse. OBJECTIVE To examine the prevalence of the undertreatment of pain, particularly among African Americans, and to recommend relevant proactive policy and practice changes to aid in eliminating this health problem.

Abstract
OBJECTIVES To review the evidence of the clinical and cost-effectiveness of anakinra, an interleukin-1 receptor antagonist (IL-1Ra), for the treatment of rheumatoid arthritis (RA) in adults. DATA SOURCES Electronic bibliographic databases. Scrip, Food and Drug Administration (FDA) submissions for new drug applications, European Agency for the Evaluation of Medicinal Products (EMEA) reports and the pharmaceutical company submission to the National Institute for Clinical Excellence. REVIEW METHODS Studies were identified that included randomised controlled trials (RCTs) or economic evaluations of anakinra in adult patients with RA. Existing health economic reviews were also assessed. Data were extracted and quality assessed using a structured approach. The Birmingham Rheumatoid Arthritis Model (BRAM) was used to compare disease-modifying antirheumatic drug (DMARD) sequences, chosen to reflect current clinical practice, with and without anakinra, at different points in the DMARD sequence. RESULTS Five high-quality RCTs of anakinra in adult patients with RA, involving a total of 2905 patients, of whom 2146 received anakinra, were identified. The results of the clinical trials were consistent with clinical benefit (compared with placebo) as measured by American College of Rheumatology (ACR) composite response rate at 6 months. Variation in response rate was seen across the trials, which is likely to be a reflection of the size of the trials and the wide range of doses evaluated. Consistent benefit was seen at the higher dose evaluated. Benefit was evident both with monotherapy and when used in combination with methotrexate. Data on the efficacy end-points evaluated in a large pragmatic safety study have not been made available, which is of concern. Anakinra treatment was associated with a high incidence of injection-site reactions. Serious adverse events were infrequent, but longer term follow-up is required. No fully published economic evaluations of anakinra in patients with RA were identified. The BRAM gives a base-case estimate of the incremental cost-effectiveness ratio (ICER) of anakinra of 106,000 pounds to 604,000 pounds/quality-adjusted life-year (QALY). In the sensitivity analyses substantial variations were made in key parameters and ICERs were shown to be responsive. However, ICERs did not drop below 50,000 pounds/QALY in any univariate sensitivity analysis. CONCLUSIONS Anakinra can be considered modestly effective in the treatment of RA based on ACR response, although no conclusion can currently be made on the effect of treatment on disease progression. Adjusted indirect comparison suggests that anakinra may be significantly less effective at relieving the clinical signs and symptoms of RA, as measured by the ACR response criteria, than tumour necrosis factor (TNF) inhibitors all used in combination with methotrexate, although these results should be interpreted with caution. The BRAM produces an ICER for anakinra substantially higher than those for infliximab and etanercept. However, patients may respond to anakinra when they have not responded to other TNF inhibitors, as these agents have a different mechanism of action. Thus, anakinra may produce a clinically significant and important improvement in some patients that they could not otherwise have achieved. Further research would be valuable in the following areas: RCTs to evaluate the efficacy, safety and cost of anakinra over the longer term; comparative trials of anakinra with other DMARDs and biological modifiers; assessment of the role of anakinra in the treatment of patients who have failed to achieve a benefit while taking infliximab or etanercept; assessment on the impact of DMARDs and anakinra on joint replacement, mortality and quality of life; controlled clinical trials of combination therapy with two anticytokines; investigations into newer biological therapies; and the utility of radiographic outcomes in clinical trials of RA.

Abstract
Abstract
Introduction
This study aimed to assess the safety and efficacy of imaging-guided percutaneous radiofrequency ablation (RFA) for local control of lung metastases from colorectal cancer (CRC).
Methods
Twenty patients with lung metastases from CRC were treated with a RITA® Starburst XL electrode and RITA® 1500 generator using temperature control and impedance monitoring. Patients received intravenous sedation and analgesia, or local anaesthetic, and stayed in hospital for at least 24 h after treatment. RFA was assessed with computed tomography (CT) at 1 week and 1 month, and then every 3 months.
Results
Forty-four CRC lung metastases in 19 patients were treated successfully at 25 treatment sessions. Five of 19 patients were retreated for new lesions. There were 13 pneumothoraces following the 25 treatments, and six patients required drainage. The median length of follow-up was 730 (range 148–924) days. Six months after treatment CT demonstrated that three lesions had progressed, 25 metastases were stable or smaller, and 11 were no longer visible. At 12 months five metastases had progressed, 11 were smaller or stable, and nine were not visible.
Conclusion
Percutaneous imaging-guided RFA was associated with modest morbidity. RFA can achieve local control of CRC lung metastases: nine of 25 metastases were not visible on CT at 12 months after treatment.

Abstract
Previous studies have shown that the viral Jun (v-Jun) oncoprotein induces marked alterations in cell cycle control, which are associated with, and may be caused by, increased cdk2 kinase activity. Since p21 CIP1 is an important regulator of cdk2, we investigated whether aberrant expression of this cyclin-dependent kinase inhibitor might contribute to cell cycle deregulation by v-Jun. We find that the basal levels of p21 CIP1 mRNA and protein expression are greatly reduced in chick embryo fibroblasts (CEF) transformed by v-Jun, and that v-Jun blocks the increases in p21 CIP1 expression that normally accompany growth inhibition induced by serum deprivation or confluency in untransformed CEF. Importantly, ectopic expression of p21 CIP1 in v-Jun-transformed CEF inhibits both cdk2 kinase activity and cell cycle progression, indicating that these alterations in p21 CIP1 expression are likely to be functionally significant for growth deregulation. We also investigated the mechanism through which v-Jun disturbs p21 CIP1 expression and the possible involvement of a known p21 CIP1 regulator, p53, as an intermediate in this process. This analysis revealed that repression is mediated primarily at the level of p21 CIP1 gene transcription, however the mechanism is complex; both p53-dependent and -independent mechanisms contribute as judged by analysis of p21 CIP1 promoter mutants and other assays of p53 transcriptional activity.

Abstract
BACKGROUND Sildenafil (Viagra), a new oral drug for the treatment of erectile dysfunction, was licensed for use across Europe in 1998. AIM To examine the effectiveness and safety of sildenafil as an oral treatment for erectile dysfunction. DESIGN OF STUDY Systematic review and meta-analysis. SETTING All published or unpublished randomised controlled trials comparing sildenafil with a placebo or alternative therapies. METHOD Published studies were sought by computerised searches of electronic databases using the keywords 'sildenafil' and 'Viagra'. A hand search was also done of the British Medical Journal, Lancet, Journal of the American Medical Association, New England Journal of Medicine, British journal of General Practice, Drug, Inpharma and Scrip. An assessment of quality of all identified studies and data extraction was undertaken independently by two researchers. Results were combined in a meta-analysis where appropriate, using RevMan version 3. RESULTS Twenty-one trials were identified. All trials showed a statistically significant improvement in erectile or sexual function in patients using sildenafil compared with a placebo. A meta-analysis of 16 trials reporting a global efficacy response showed that men were 3.57 (95% CI = 2.93-4.43) times as likely to have improved erections on sildenafil compared with those on a placebo. The number needed to treat to have one man with improved erections was two. The drug has a relatively safe side-effect profile. CONCLUSIONS Available research shows that sildenafil is an effective treatment for male erectile dysfunction. Many trial participants had some baseline erectile function and it is probable that in clinical practice, where the erectile function tends to be more impaired, the number needed to treat may be higher.

Abstract
Neuroprotectants are drugs designed to treat stroke by preserving ischemic neurons in the penumbra. Despite numerous studies over the past ten years, no such drug has yet shown clinical efficacy. This article reviews those trials completed since 1999, including assessments of drugs that modify receptors or ion flow, block leukocyte adhesion receptors or stabilize membranes. In addition, ongoing trials and early trials using novel mechanisms of action, such as hypothermia and antioxidants, are discussed.

Abstract
The uremic syndrome is a complex mixture of organ dysfunctions, which is attributed to the retention of a myriad of compounds that under normal condition are excreted by the healthy kidneys (uremic toxins). In the area of identification and characterization of uremic toxins and in the knowledge of their pathophysiologic importance, major steps forward have been made during recent years. The present article is a review of several of these steps, especially in the area of information about the compounds that could play a role in the development of cardiovascular complications. It is written by those members of the Uremic Toxins Group, which has been created by the European Society for Artificial Organs (ESAO). Each of the 16 authors has written a state of the art in his/her major area of interest.
