Abstract
INTRODUCTION A well-established method does not exist to rule out a small bowel obstruction using an abdominal xray series with significant accuracy. The hypothesis of the study is that the ratio of an average small bowel diameter to lumbar spine diameter over 0.5 is most likely a small bowel obstruction. METHODS An x-ray abdominal series measurement technique was applied to 41 subjects with a chief complaint of "abdominal pain" as part of a randomized retrospective case review to predict an obstruction v. non obstruction. A total number of 81 abdominal pain subjects with a mean age of 46.7 years were selected with 40 excluded due to normal small bowel gas pattern. The subject's medical information was unknown to the authors when reading their images. The measurement technique involved averaging the largest and smallest small bowel short axis diameters with comparison to the lowest clearly visible lumbar body width. The subjects' medical course as described in the medical chart or subsequent computed tomography scans were used as the referencing standard to determine presence of obstruction vs non-obstruction. RESULTS This method, called the Bowel-Spine Ratio (BSR), resulted in a sensitivity of 0.882 (0.622-0.979; 95% CI), specificity of 0.957 (0.760-0.998; 95% CI), accuracy of 94.7% (80.9%-99.1%; 95% CI) and a positive likelihood ratio of 21 for predicting a small bowel obstruction. CONCLUSION The abdominal series Bowel-Spine Ratio is a simple yet effective technique to screen for a small bowel obstruction using limited resources and to avoid unnecessary computed tomography scans with the potential to reduce health care costs. IMPLICATIONS FOR PRACTICE Clinicians could have increased confidence in utilizing abdominal radiographs to evaluate for small bowel obstruction.

Abstract
PURPOSE Many people do not participate in mail-out bowel cancer screening programs due to difficulties using the screening kit. The current study investigated the ways the screening kit could be modified to improve usability. METHODS 1,109 people evaluated 15 different screening kit modifications. Participants reported on how these kit modifications would affect their screening barriers, their future screening intentions, and how much they would recommend that the modification is made to the current screening kit used the program. All responses were given via an online survey conducted between April and December of 2021. RESULTS Seventeen percent of previous NBCSP non-participators indicated that a one-sample test would increase their intention to participate. Recommendation ratings demonstrated higher levels of support for modifications that included providing a barcode naming label (M = 9.06, 95% CI [8.81, 9.31]), having a larger diameter opening of the collection tube (M = 8.42, 95% CI [8.10, 8.74]), and highlighting the expiry date on the kit packaging (M = 8.59, 95% CI [8.29, 8.89]). There were lower levels of support for modifications that reduced the size of the packaging the kit is sent in (M = 6.47, 95% CI [6.09, 6.85]), removed branding from kit packaging (M = 5.98, 95% CI [5.57, 6.39]), and removed the information booklet that comes with the screening kit (M = 5.25, 95% CI [4.78, 5.72]). CONCLUSION These findings highlight multiple ways in which bowel cancer screening kits can be changed to increase usability for invitees of national bowel cancer screening programs. Findings have implications for all screening programs that use immunochemical-based bowel cancer screening kits.

Abstract
The COVID-19 pandemic has significantly impacted educators, both personally and professionally. However, very little is known about the extent of these impacts among educators' serving children with intellectual and developmental disabilities (IDD). The present study surveyed 230 educators (teachers, staff, and administrators) to assess their wellbeing, concerns during the pandemic, and perceived importance of various COVID-19 school mitigation strategies. Data were gathered May/June of 2021 from two separate school districts, one in the Midwest and the other in the Mid-Atlantic, serving children with IDD. Nearly half of all survey respondents reported poor wellbeing. Almost all educators reported health of themselves, students, and family members was their greatest concern when compared to pandemic-related disruption of their duties or benefits (e.g., not having enough sick time). Most educators felt disinfecting routines, vaccinations, and daily health checks were the most helpful in preventing the spread of COVID-19 in schools, while in-school mask mandates and weekly testing of students and staff were perceived as less helpful. Our findings suggest that efforts are needed to support the wellbeing of educators during these challenging times. When pandemic-related policies and procedures are decided by administrators, our data suggest educators will review decisions within the framework of health and safety of themselves, their students, and families. Understanding this framework may be particularly valuable when considering implementation of COVID-19 policies, like masking and COVID-19 testing, that are less preferred.

Abstract
Studies evaluating the influence of health literacy on patient behavior and outcomes suggest a positive relationship between health literacy and health knowledge, health behaviors, and health status. In Latin American countries, studies assessing health literacy are few, regional, and demonstrate considerable variation, with reported rates of adequate health literacy ranging from 5.0% to 73.3%. In this paper, we examine and explore the state of health literacy and efforts to promote it in Latin America. Key challenges to those efforts include socioeconomic inequality, social/geographic isolation, and cultural-, language-, and policy-related barriers, many of which disproportionately affect indigenous populations and others living in rural areas. Greater use of infographics, videos, and mobile apps may enhance health literacy and patient empowerment, especially when language barriers exist. This paper provides strategies and tools for tailored programming, examples of successful health literacy interventions, and policy recommendations to improve health literacy in Latin America, intending to spur additional discussion and action. Centrally organized collaboration across multiple sectors of society, with community involvement, will enhance health literacy and improve health and well-being across Latin America.

Abstract
Animal health emergencies can also have serious socio-economic and public health consequences, including impacts on human health, as well as food security and safety. Therefore, policy-makers and advisers should take an active part in the development of emergency management systems. A formally structured animal health emergency management system sets out, in a systematic way, the elements required to achieve the necessary level of preparedness, and provides for planning and implementation of the appropriate actions to be taken in an emergency. Good emergency management practices, as laid down by the Emergency Management Centre for Animal Health (EMC-AH) of the Food and Agriculture Organization of the United Nations, should incorporate all four phases of an animal health event: peacetime (i.e. before the event occurs), alert, emergency and reconstruction. Five actions are implemented before, during and after an animal health event: prepare, prevent, detect, respond and recover. A strategic action plan can be drafted to schedule the activities required to develop the emergency management system and increase a country's level of preparedness, step by step. The EMC-AH aims to support all components of emergency management at the national, regional and international levels along this progressive pathway for emergency preparedness.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
The global community continues to incur the high costs of crisis mitigation and emergency response to outbreaks of emerging infectious diseases, such as those caused by the H5N1 highly pathogenic avian influenza virus, Ebola virus, Nipah virus, Zika virus or the Middle East respiratory syndrome coronavirus. These viruses are particularly dangerous in regions associated with poor development indicators and high vulnerability. The drivers of these disease crises include failures in the way that animal diseases are detected and reported and failures in the way in which disease response is implemented by animal health and public health systems. In addition, the lack of a coordinated response hampers disease control efforts. A comprehensive approach for disease prevention, detection and response, however, requires a coordinated and joint effort among governments, communities, donors and international networks to invest effectively in prevention systems that can identify early signals of the emergence, spillover and spread of animal pathogens at the local level. These signals include trade bans, market closures, civil unrest, heavy rains and droughts associated with climate change, and livestock intensification or changes in consumer behaviour. The global community needs to increase its investment in early warning and detection systems that can provide information that enables action to be taken at the national, regional and global levels in the event of an outbreak of a transboundary animal disease (TAD). Like any preventive measure, an early warning system requires financial resources, but these are insignificant when compared to the losses that are avoided. Building a global early warning and effective response system for outbreaks is value for money, as the benefits far outweigh the costs. The goal of the Food and Agriculture Organization of the United Nations (FAO) is to end hunger and poverty, which is a challenging and complex task. Building global capacity to prepare for and respond to TADs is an important element of the FAO's strategic objective to increase the resilience of livelihoods to threats and crises. Each year, livestock, and the people who rely upon them for their livelihoods, are confronted with animal disease and crises. They can strike suddenly, causing obvious illness and death, or emerge insidiously and become well established before becoming apparent. Animal disease emergencies threaten the production of, and access to, food; consequently, one of the FAO's missions is to help countries to prepare for and respond to animal health disasters.

Abstract
Background: Population mail-out bowel screening programs are a convenient, cost-effective and sensitive method of detecting colorectal cancer (CRC). Despite increased survival rates associated with early detection of CRC, in many countries 50% or more of eligible individuals do not participate in such programs, resulting in a substantial amount of cancers progressing undetected and wasted public health resources. Aim: The current study aimed to systematically review all of the interventions that have been applied internationally to increase fecal occult blood test (FOBT) kit return, specifically in population mail-out programs, to make recommendations to policy makers and program organizers as to the most effective methods of increasing uptake. Method: Six electronic databases (PubMed, PsycINFO, Scopus, InformIT, CINAHL, and ProQuest Dissertations and Theses) were searched for articles published in English before 10th of March 2018. Studies were included if they reported the results of an intervention designed to increase the return of FOBT kits that had been mailed to individuals' homes. Results: PRISMA systematic review reporting methods were applied and each study was assessed using Cochrane's risk of bias tool. The quality of evidence was assessed using GRADE guidelines. The review identified 53 interventions from 30 published studies. Nine distinct intervention strategy types were identified and pooled risk ratios and confidence intervals were estimated for each intervention type. Four key effective intervention strategies were identified including telephone contact, GP endorsement, simplified test procedures, and advance notification with small to moderate effect sizes. Conclusions: Interventions that combine program-level changes incorporating the issue of advance notification and alternative screening tools with the involvement of primary health professionals through endorsement letters and telephone contact should lead to increases in kit return in mail-out CRC screening programs. Future research should examine the benefit of combining intervention strategies and tailoring to specific populations.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
Social instability occurs as a consequence of war, civil strife or natural disasters such as earthquakes, floods and droughts. Animal diseases, including zoonoses, can be both a precursor to social instability and a result of social instability. Coping mechanisms, such as sound policies, trust in government, and robust infrastructure break down at times of civil instability. Such breakdowns often lead to a decline in both public health and the food and agricultural livestock base, thus creating a vicious cycle that involves inadequate nutrition, threatened livelihoods, and fewer opportunities for safe trade. This article is principally a discussion of a theoretical nature on the dynamics between animal diseases and social instability. Based on their experience of working for the Food and Agriculture Organization of the United Nations (FAO), the authors provide numerous examples of the connection between the two, mostly in countries that have fragile environments and are experiencing protracted crises. Disease has a direct and immediate effect on a community, but, in addition, if the community is not able to recover from the impact of a disease on their health and livelihoods, the consequences of an outbreak can persist even after the disease is no longer present. Stability, therefore, depends on a variety of factors, including the ability of a community to overcome the effects of a disease outbreak or other destabilising event. The FAO approach to helping families and communities to cope with the destabilizing effects of animal diseases is to build resilience, particularly amongst the most vulnerable households. This requires individuals and governments to gain a better understanding of what drives disease at the interface between human and animal health. In addition, it requires governments to invest in social protection programmes, establish a long-term risk reduction strategy that decreases vulnerability, and improve the sustainability of safe agricultural and marketing practices.

Abstract
Chronic inflammation has been associated with a variety of human cancers including prostate cancer. Interleukin-17 (IL-17) is a critical pro-inflammatory cytokine, which has been demonstrated to promote development of prostate cancer, colon cancer, skin cancer, breast cancer, lung cancer, and pancreas cancer. IL-17 promotes prostate adenocarcinoma with a concurrent increase of matrix metalloproteinase 7 (MMP7) expression in mouse prostate. Whether MMP7 mediates IL-17’s action and the underlying mechanisms remain unknown. We generated Mmp7 and Pten double knockout (Mmp7−/− in abbreviation) mouse model and demonstrated that MMP7 promotes prostate adenocarcinoma through induction of epithelial-to-mesenchymal transition (EMT) in Pten-null mice. MMP7 disrupted E-cadherin/β-catenin complex to up-regulate EMT transcription factors in mouse prostate tumors. IL-17 receptor C and Pten double knockout mice recapitulated the weak EMT characteristics observed in Mmp7−/− mice. IL-17 induced MMP7 and EMT in human prostate cancer LNCaP, C4-2B, and PC-3 cell lines, while siRNA knockdown of MMP7 inhibited IL-17-induced EMT. Compound III, a selective MMP7 inhibitor, decreased development of invasive prostate cancer in Pten single knockout mice. In human normal prostates and prostate tumors, IL-17 mRNA levels were positively correlated with MMP7 mRNA levels. These findings demonstrate that MMP7 mediates IL-17’s function in promoting prostate carcinogenesis through induction of EMT, indicating IL-17-MMP7-EMT axis as potential targets for developing new strategies in the prevention and treatment of prostate cancer.

Abstract
BACKGROUND/PURPOSE The diagnosis of patients with pulmonary infiltrates and human immunodeficiency virus (HIV) infection remains a challenge. In current clinical practice the gold standard for Pneumocystis jirovecii pneumonia (PCP) diagnosis remains the identification of the organism in bronco alveolar lavage (BAL) using microscopy (e.g., silver stain). (1->3)-β -d-glucan (BG) is a polysaccharide that is present within the cell wall of Pneumocystis and other fungi. METHODS We analyzed serum and BAL lavage fluid from a cohort of 119 patients that did have HIV, a diagnosis of pneumonia and underwent bronchoscopy (FOB) for diagnosis of PCP. RESULTS The discriminative power of serum BG for the diagnosis of PCP in this group of patients was very high. Using a cutoff of 300 pg/mL, the sensitivity, specificity, positive predictive value(PPV) and negative predictive value (NPV) were 91%, 92%, 89% and 93% respectively. A model for ROC with just serum BG (N = 108) had an AUC of 0.95. Serum procalcitonin (PCT) and BAL BG were not as accurate for the diagnosis of PCP. For BAL BG using a cutoff of 783 pg/mL, the sensitivity,specificity, positive predictive value (PPV) and negative predictive value (NPV) were 72%, 79%,72% and 79% respectively. The differences between the medians for serum PCT between the group with a without PCP did not reach statistical significance (p = 0.6137). CONCLUSION The measurement of serum BG should be incorporated in the diagnostic work up of HIV positive patients with dyspnea and infiltrates on chest X X-ray. Our study confirms the diagnostic value of serum BG previously reported by others but we add a cutoff value that we believe is more accurate for patients with AIDS and suspicion of PCP.

Abstract
Diffuse alveolar hemorrhage (DAH) from systemic lupus erythematosus (SLE) is a rare but potentially life-threatening condition. We report the case of a 14-year-old female with SLE who developed hypoxia and shock secondary to severe alveolar hemorrhage. She was successfully managed by placement on extracorporeal membrane oxygenation (ECMO) followed by emergent pulmonary lobectomy and medical treatment including high-dose methylprednisolone, cyclophosphamide, intravenous immunoglobulin, and plasmapheresis.

Abstract
The objective of our study was to identify genetic factors that regulate bone mineral density (BMD) in mice using well defined recombinant inbred strains. For this purpose we chose the BXD recombinant inbred (RI) strains derived from progeny of the C57BL/6J (B6) and DBA/2J (D2) progenitor strains. We sampled both male and female mice (∼4 each) of 46 strains at 3 months-of-age, measured their BMD, and conducted QTL mapping. The data were analyzed to identify candidates genes contained within the most significant quantitative trait locus (QTL). Evaluation of candidate genes included functional assessment, single nucleotide polymorphism (SNP) genotyping and direct sequencing. We established that there was a QTL for BMD in males on chromosome 15 that has the impact larger than QTLs on all other chromosomes. The QTL on chromosome 15 was narrowed to a genomic region between 38 Mbp and 52 Mbp. By examining transcripts within this region, we found an important candidate gene: trichorhinophalangeal syndrome, type I (Trps1). SNP analysis identified a nonsynonymous SNP (rs32398060) in Trps1 that co-segregated with bone mineral density. Analysis of association between this SNP within TRPS1 and BMD in a human population confirmed its significance.

Abstract
OBJECTIVE To test the hypothesis that autoantigen modifications by peptidylarginine deiminase type 4 (PAD-4) increase immunoreactivity. METHODS We assembled sera from patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Felty's syndrome (FS), and antineutrophil cytoplasmic antibody-associated vasculitides (AAVs), as well as sera from control subjects without autoimmune diseases. The sera were tested for binding to activated neutrophils, deiminated histones, and neutrophil extracellular chromatin traps (NETs). IgG binding to lipopolysaccharide-activated neutrophils was assessed with confocal microscopy, and binding to in vitro-deiminated histones was measured using enzyme-linked immunosorbent assay (ELISA) and Western blotting. In addition, we quantitated histone deimination in freshly isolated neutrophils from the blood of patients and control subjects. RESULTS Increased IgG reactivity with activated neutrophils, particularly binding to NETs, was paralleled by preferential binding to deiminated histones over nondeiminated histones by ELISA in a majority of sera from FS patients but only in a minority of sera from SLE and RA patients. Immunoblotting revealed autoantibody preference for deiminated histones H3, H4, and H2A in most FS patients and in a subset of SLE and RA patients. In patients with AAVs, serum IgG preferentially bound nondeiminated histones over deiminated histones. Increased levels of deiminated histones were detected in neutrophils from RA patients. CONCLUSION Circulating autoantibodies in FS are preferentially directed against PAD-4-deiminated histones and bind to activated neutrophils and NETs. Thus, increased reactivity with modified autoantigens in FS implies a direct contribution of neutrophil activation and the production of NET-associated nuclear autoantigens in the initiation or progression of FS.

Abstract
BACKGROUND Etanercept, infliximab and adalimumab are licensed in the UK for the treatment of active and progressive psoriatic arthritis (PsA) in adults who have an inadequate response to standard treatment. OBJECTIVE To determine the clinical effectiveness, safety and cost-effectiveness of these biologic agents in the treatment of active and progressive PsA. DATA SOURCES Systematic reviews were performed, with data sought from 10 electronic databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Science Citation Index, Conference Proceedings Citation Index - Science, ClinicalTrials.gov, metaRegister of Current Controlled Trials, NHS Economic Evaluation Database, Health Economic Evaluations Database and EconLit) up to June 2009. REVIEW METHODS Full paper manuscripts of titles/abstracts considered relevant were obtained and assessed for inclusion by two reviewers according to criteria on study design, interventions, participants and outcomes. Data on study and participant characteristics, efficacy outcomes, adverse effects, costs to the health service and cost-effectiveness were extracted, along with baseline data where reported. The primary efficacy outcomes were measures of anti-inflammatory response, skin lesion response and functional status, and the safety outcome was the incidence of serious adverse events. The primary measure of cost-effectiveness was incremental cost per additional quality-adjusted life-year (QALY). Standard meta-analytic techniques were applied to efficacy data. Published cost-effectiveness studies and the economic analyses submitted to the National Institute for Health and Clinical Excellence (NICE) by the biologic manufacturers were reviewed. An economic model was developed by updating the model produced by the York Assessment Group for the previous NICE appraisal of biologics in PsA. RESULTS Pooled estimates of effect demonstrated a significant improvement in patients with PsA for all joint disease and functional status outcomes at 12-14 weeks' follow-up. The biologic treatment significantly reduced joint symptoms for etanercept [relative risk (RR) 2.60, 95% confidence interval (CI) 1.96 to 3.45], infliximab (RR 3.44, 95% CI 2.53 to 4.69) and adalimumab (RR 2.24, 95% CI 1.74 to 2.88), with 24-week data demonstrating maintained treatment effects. Trial data demonstrated a significant effect of all three biologics on skin disease at 12 or 24 weeks. Evidence synthesis found that infliximab appeared to be most effective across all outcomes of joint and skin disease. The response in joint disease was greater with etanercept than with adalimumab, whereas the response in skin disease was greater with adalimumab than with etanercept, although these differences are not statistically significant. Under base-case assumptions, etanercept was the most likely cost-effective strategy for patients with PsA and mild-to-moderate psoriasis if the threshold for cost-effectiveness was £20,000 or £30,000 per QALY. All biologics had a similar probability of being cost-effective for patients with PsA and moderate-to-severe psoriasis at a threshold of £20,000 per QALY. LIMITATIONS Limited available efficacy data and difficulty in assessing PsA activity and its response to biologic therapy. CONCLUSIONS The data indicated that etanercept, infliximab and adalimumab were efficacious in the treatment of PsA compared with placebo, with beneficial effects on joint symptoms, functional status and skin. Short-term data suggested that these biologic agents can delay joint disease progression and evidence to support their use in the treatment of PsA is convincing. Future research would benefit from long-term observational studies with large sample sizes of patients with PsA to demonstrate that beneficial effects are maintained, along with further monitoring of the safety profiles of the biologic agents.

Abstract
The occurrence of a hypercoagulable state and decreasing concentration of ADAMTS 13 in late pregnancy and during the postpartum period increases the risk for a woman to develop life-threatening thrombotic thrombocytopenic purpura (TTP). This is also the time of great risk for the more common obstetric complications of preeclampsia; eclampsia; and hemolysis, elevated liver functions tests, low platelets (HELLP) syndrome. These conditions are associated with high maternal and perinatal mortality. Differential diagnosis may be difficult due to the overlapping of clinical and laboratory findings, including thrombocytopenia, microangiopathic hemolytic anemia, neurologic symptoms, and renal insufficiency, making it difficult or impossible to distinguish them from TTP. Management of microangiopathic disorders encountered during pregnancy differ; therefore, an accurate diagnosis is required. Outcomes of TTP without plasma exchange therapy (TPE) are almost uniformly fatal. Early recognition and management of symptoms with prompt and aggressive TPE is essential when TTP is suspected.

Abstract
The ongoing US Glatiramer Acetate (GA) Trial is the longest evaluation of continuous immunomodulatory therapy in relapsing-remitting multiple sclerosis (RRMS). The objective of this study was to evaluate up to 15 years of GA as a sole disease-modifying therapy. Two hundred and thirty-two patients received at least one GA dose since study initiation in 1991 (mITT cohort), and 100 (43%, Ongoing cohort) continued as of February 2008. Patients were evaluated every 6 months using the Expanded Disability Status Scale (EDSS). Mean GA exposures were 8.6 +/- 5.2, 4.81 +/- 3.69, and 13.6 +/- 1.3 years and mean disease durations were 17, 13, and 22 years for mITT, Withdrawn and Ongoing cohorts, respectively. For Ongoing patients, annual relapse rates (ARRs) maintained a decline from 1.12 +/- 0.82 at baseline to 0.25 +/- 0.34 per year; 57% had stable/improved EDSS scores (change < or = 0.5 points); 65% had not transitioned to secondary progressive multiple sclerosis (SPMS); 38%, 18%, and 3% reached EDSS 4, 6, and 8. For all patients on GA therapy (the mITT cohort), ARRs declined from 1.18 +/- 0.82 to 0.43 +/- 0.58 per year; 54% had stable/improved EDSS scores; 75% had not transitioned to SPMS; 39%, 23%, and 5% reached EDSS 4, 6, and 8. In conclusion, multiple sclerosis patients with mean disease duration of 22 years administering GA for up to 15 years had reduced relapse rates, and decreased disability progression and transition to SPMS. There were no long-term safety issues.

Abstract
A survey of registered nurses working in two acute medicine acute medicine units (AMUs) was conducted between May & September 2009 to enable a focussed understanding of nursing recruitment and retention, to guide nurse managers for future workforce planning. The NHS collects national information regarding recruitment, retention and leavers, but this is sporadic and hampered by a lack of feedback to clinical areas. In this study, fifty completed questionnaires were collated, totalling a response rate of 57.5%. The results demonstrate that while recruitment is currently buoyant, nurses with significant experience are becoming dissatisfied through lack of opportunity to advance. It concludes that further national research is required to inform a strategy fit for the future development of nursing in acute medicine.

Abstract
OBJECTIVES To examine the impact of presumed consent legislation on organ donation and to review data on attitudes to presumed consent among the public, professionals and any other stakeholders. DATA SOURCES Eight electronic databases (MEDLINE, MEDLINE In-Process, EMBASE, CINAHL, PsycINFO, HMIC, PAIS International and OpenSIGLE) were searched from inception to January 2008. Supplementary internet searches were also performed. REVIEW METHODS A systematic review of studies comparing donation rates in a single country before and after the introduction of a presumed consent law or in countries with and without presumed consent systems. The methodological quality of these studies was assessed and a narrative synthesis of results undertaken. Surveys of attitudes towards presumed consent legislation were also included. RESULTS Over 2000 potentially relevant citations were identified, of which 13 studies met the inclusion criteria for the primary objective and 13 for the secondary objective. For the primary objective, eight studies were between-country comparisons and five were before-and-after studies. Four of the between-country comparisons were of sufficient methodological quality to provide reliable results. In all four studies presumed consent law or practice was associated with increased rates of organ donation, ranging from an increase of 2.7 donors per million population (pmp) in one study to 6.14 donors per million in another, and an increase of between 20% and 30% in two other studies. Factors other than presumed consent that had an impact on organ donation rates were mortality from road traffic accidents and cerebrovascular accident, the transplant capacity of a country, gross domestic product per capita and health expenditure per capita, religion, education, public access to information and a common law legal system. The five before-and-after studies represented three countries, all of which reported an increase in donation rates following the introduction of a presumed consent system (Austria, from 4.6 to 27.2 donors pmp over a 5-year period; Belgium, increase in kidney donation from 10.9 to 41.3 pmp during a 3-year period; Singapore, increase in kidney procurement from 4.7 to 31.3 per year in the 3 years after the change in legislation). There was very limited investigation of any other changes taking place concurrently with the changes in legislation across this set of studies. Of the 13 studies addressing the secondary objective, eight were surveys of the UK public, four were from other countries and one was an international survey of health professionals. There was variation among the UK surveys in the level of support for presumed consent, with surveys conducted before 2000 reporting the lowest levels of support (28-57%). The most recent survey by YouGov in 2007 reported that 64% of respondents supported a change to presumed consent. CONCLUSIONS Presumed consent alone is unlikely to explain the variation in organ donation rates between different countries. A combination of legislation, availability of donors, transplantation system organisation and infrastructure, wealth and investment in health care, as well as underlying public attitudes to and awareness of organ donation and transplantation, may all play a role, although the relative importance of each is not clear. Further reviews could investigate the factors likely to modify donor rates, such as procedures for family involvement. The way in which families of any potential donor are approached is likely to be an important factor and a review of qualitative research examining the experience of relatives in this context would be useful.
