Abstract
The silencing of large chromosomal regions by epigenetic mechanisms has been reported to occur frequently in cancer. Epigenetic marks, such as histone methylation and acetylation, are altered at these loci. However, the mechanisms of formation of such aberrant gene clusters remain largely unknown. Here, we show that, in cancer cells, the epigenetic remodeling of chromatin into hypoacetylated domains covered with histone H3K27 trimethylation is paralleled by changes in higher-order chromatin structures. Using fluorescence in situ hybridization, we demonstrate that regional epigenetic silencing corresponds to the establishment of compact chromatin domains. We show that gene repression is tightly correlated to the state of chromatin compaction and not to the levels of H3K27me3-its removal through the knockdown of EZH2 does not induce significant gene expression nor chromatin decompaction. Moreover, transcription can occur with intact high-H3K27me3 levels; treatment with histone deacetylase inhibitors can relieve chromatin compaction and gene repression, without altering H3K27me3 levels. Our findings imply that compaction and subsequent repression of large chromatin domains are not direct consequences of PRC2 deregulation in cancer cells. By challenging the role of EZH2 in aberrant gene silencing in cancer, these findings have therapeutical implications, notably for the choice of epigenetic drugs for tumors with multiple regional epigenetic alterations.

Abstract
BACKGROUND To date, no studies have explored the role of carers in supporting adults with intellectual disabilities (ID) and obesity during a weight loss intervention. The present study explored perceptions of carers supporting adults with ID, as they participated in a 6-month multi-component weight loss intervention (TAKE 5). METHODS Semi-structured interviews were used to explore the experiences of 24 carers. The transcripts were analysed qualitatively using thematic analysis. RESULTS Three themes emerged from the analysis: carers' perceptions of participants' health; barriers and facilitators to weight loss; and carers' perceptions of the weight loss intervention. Data analysis showed similarities between the experiences reported by the carers who supported participants who lost weight and participants who did not. Lack of sufficient support from people from the internal and external environment of individuals with ID and poor communication among carers, were identified as being barriers to change. The need for accessible resources tailored to aid weight loss among adults with ID was also highlighted. CONCLUSION This study identified specific facilitators and barriers experienced by carers during the process of supporting obese adults with ID to lose weight. Future research could utilise these findings to inform appropriate and effective weight management interventions for individuals with ID.

Abstract
BACKGROUND While symptomatic venous thromboembolism adversely impacts survival among cancer patients, the outcome of cancer patients with unsuspected pulmonary embolism (UPE) found on routine cancer staging multi-row detector computed tomography (MDCT) scans is unknown. OBJECTIVE To determine whether UPE detected on routine staging MDCT scans impacts overall survival among cancer patients. PATIENTS AND METHODS We performed a matched cohort study of cancer patients diagnosed with UPE on routine staging scans between May 2003 and August 2006. Two controls (n = 137) were individually matched by age (± 5 years), cancer type and stage for each UPE patient (n = 70). We used Cox's proportional hazard models to compare the mortality between UPE patients and their matched controls. RESULTS The hazard ratio (HR) for death among UPE patients was 1.51 (95% CI 1.01-2.27, P = 0.048). Compared with their matched controls, patients with UPE more proximal than the subsegmental arterial branches had a HR for death at 6 months of 2.28 (95% CI 1.20-4.33, P = 0.011) and an overall HR of 1.70 (95% CI 1.06-2.74, P = 0.027). Survival among UPE patients with isolated subsegmental PE (ISSPE) was not significantly different than that of matched controls (HR 1.04 95% CI 0.44-2.39, P = 0.92). CONCLUSIONS UPE identified more proximal than the subsegmental arterial branches has a significant negative impact on survival among cancer patients.

Abstract
Obesity is more prevalent in adults with intellectual disabilities than in the general population, and has been shown to contribute to their reduced life expectancy, and increased health needs. Relatively few studies have examined the effectiveness of weight loss interventions for adults with intellectual disabilities. However, there is evidence to support interventions that take account of the context of the lives of adults with intellectual disabilities, including carer involvement in interventions. To reduce the health inequalities experienced by adults with intellectual disabilities, there is a clear need to develop accessible, evidence-based clinical weight management services.

Abstract
People with intellectual disabilities experience significant health inequalities compared with the general population, including a shorter life expectancy and high levels of unmet health needs. Another accepted measure of health inequalities, the prevalence of obesity, has been shown to be higher in adults with intellectual disabilities than in the general population. While the factors contributing to the increased prevalence among adults with intellectual disabilities are not well understood, the high rates of obesity among younger adults highlight the need for further research involving children and adolescents with intellectual disabilities. To take forward the priorities for research and the development of effective, accessible services, there is a need for collaboration between professionals working in the fields of intellectual disabilities and obesity.

Abstract
We describe the development of the Safe Tractor Assessment and Rating System (STARS), a design-based tractor safety rating system that can be applied to new or used tractors to provide an objective assessment of their inherent safety features. A predictive rating system model, based on technical inspection, was used. Key principles underlying the system included the potential for design features to reduce the risk of an injury event occurring, and to reduce the risk of injury if such an event did occur. The rating system was based on current standards, research literature, injury and fatality data, and farmer input via focus groups. Development was an iterative process involving field, pilot, and inter-rater reliability tests. The final system was divided into six domains: rollover protection, runover protection, user protection, information and controls, pedestrian protection, and options. Within each domain, optimum design features were described for the common or serious potential injury risks, and a score was assigned for each feature. Scores were translated into a star rating, from zero stars for virtually no inherent safety features to five stars for the highest inherent safety, for each of the six domains. STARS distinguished well between older tractor models known to have few inherent safety features and newer tractor models known to have higher levels of inherent safety. STARS can provide tractor manufacturers, dealers, and users with information critical for managing tractor-associated injury risk. In Australia, it is initially being implemented within the curriculum of the technical education and training sector.

Abstract
Objective: To prioritize varicose vein (VV) waiting lists, superficial venous reflux was timed in patients with primary VVs using hand-held Doppler (HHD) and classified as 'severe' (≤4s), 'moderate' (>4; ≤6s) or 'mild' (>6s). Only patients with severe reflux were offered surgery. The progression of reflux in those not offered surgery was investigated over two years. Methods: Patients seen in the VV clinic between November 1999 and October 2000 with reflux ≥4s were re-assessed two years later. Reflux was timed at the saphenofemoral (SFJ) and saphenopopliteal (SPJ) junctions using HHD. Patients completed a basic symptom questionnaire. The severity of VVs and skin changes of venous insufficiency were graded. Results: In all, 38/54 patients attended for review at two years. There were 44 limbs with 48 sites of reflux, 38 at the SFJ and 10 at the SPJ. Reflux improved at 27 sites, remained the same at five and deteriorated at 16. Reflux became 'severe' in eight limbs, but only four patients requested surgery. Median (interquartile range) reflux time was 6.0 (5–6)s in 1999–2000 and 7.0 (4–10)s in 2002 ( P = 0.13). Median symptom scores for aching and the severity of VV remained unchanged. The cosmetic appearance of VV and skin signs of venous insufficiency significantly improved ( P < 0.01). Conclusions: Mild and moderate reflux did not deteriorate in most VV patients. HHD may be a useful adjunct to grade venous reflux and prioritize patients for VV surgery.

Abstract
BACKGROUND Interest in the possibility of intraoperative analysis of sentinel lymph nodes to select patients with operable breast cancer for immediate axillary clearance encouraged this review of a long-term experience of selective axillary surgery based on intraoperative contact cytology of conventionally sampled nodes. Survival was assessed as a potential marker for understaging. METHODS Records of 437 patients who had surgery between 1991 and 1994 were reviewed to compare rates of axillary recurrence in patients who had contact cytology only with those who had contact cytology and axillary clearance. RESULTS Axillary recurrence occurred in seven (3 per cent) of 219 patients who had negative contact cytology, three (4 per cent) of 75 patients who had positive contact cytology with axillary clearance and one (1 per cent) of 93 who had axillary clearance alone. In patients with positive contact cytology, 131 (78 per cent) of 168 positive nodes were in the sample specimen, which included all positive nodes on 19 occasions. Survival probability at 36, 72 and 96 months was 92, 87 and 84 per cent respectively for patients with negative contact cytology, and 85, 73 and 71 per cent for patients with positive cytology and axillary clearance. CONCLUSION A selective approach to axillary surgery based on intraoperative contact cytology of sampled lymph nodes gave good long-term control of axillary disease.

Abstract
Despite a large increase in NHS funding, the rate of activity has slowed and may be decreasing. Elective activity has fallen at times when more money is going in. Growth in elective activity has tended to be in planned admissions, which have no direct impact on waiting lists. Unless money is redirected into activity-generating areas that impact on waiting times, the NHS will struggle to deliver on waiting-time targets.

Abstract
The government is committed to raise spending on healthcare in the UK up to the European average by 2006. There is debate about the exact target figure, but agreement that the key consideration is how the extra money will be spent. If the UK is to achieve the EU average, it will probably have to increase private as well as public spending. To match German levels of staffing, the UK would need an extra 100,000 doctors and 300,000 nurses. There has been little analysis of how the extra expenditure will improve outcomes.
