Search for the Standard Model Higgs boson decay to μ+μ− with the ATLAS detector

A search is reported for Higgs boson decay to μ+μ−μ+μ− using data with an integrated luminosity of 24.8 fb−124.8 fb−¹ collected with the ATLAS detector in pp collisions at √s=7 and 8 TeV at the CERN Large Hadron Collider. The observed dimuon invariant mass distribution is consistent with the Standard Model background-only hypothesis in the 120–150 GeV search range. For a Higgs boson with a mass of 125.5 GeV, the observed (expected) upper limit at the 95% confidence level is 7.0 (7.2) times the Standard Model expectation. This corresponds to an upper limit on the branching ratio BR(H→μ+μ−)of 1.5×10−31.5×10−3

A comparison of prostate cancer survival in England, Norway and Sweden: a population-based study.

PURPOSE: The objective of the study was to compare patterns of survival 2001-2004 in prostate cancer patients from England, Norway and Sweden in relation to age and period of follow-up. SUBJECTS AND METHODS: Excess mortality in men with prostate cancer was estimated using nation-wide cancer register data using a period approach for relative survival. 179,112 men in England, 23,192 in Norway and 59,697 in Sweden were included. RESULTS: In all age groups, England had the lowest survival, particularly so among men aged 80+. Overall age-standardised five-year survival was 76.4%, 80.3% and 83.0% for England, Norway and Sweden, respectively. The majority of the excess deaths in England were confined to the first year of follow-up. CONCLUSION: The results indicate that a small but important group of older patients present at a late stage and succumb early to their cancers, possibly in combination with severe comorbidity, and this situation is more common in England than in Norway or Sweden

Investigating the factors influencing professional identity of first-year health and social care students

Interprofessional education (IPE) involves students from different professions being brought together to learn about each other's profession. Several models of IPE exist, and central to the debate around which of these models is the most appropriate is the question of the stage of training in which to implement these programmes. Currently, however, there is no consensus on this question. Debate so far has revolved around the strength of professional identities, or lack thereof, amongst pre-qualifying students and how this may influence interprofessional learning. The potential role of professional identity in IPE seems to be unresolved. The present article adds to this debate by investigating the level of professional identity when students commence their professional studies; the differences in the level of professional identity between students from a range of professions; and the factors which may affect the initial levels of professional identification. Data were collected by questionnaire from the first-year cohort of Health and Social Care (H&SC) students embarking on IPE as an embedded part of an undergraduate pre-qualifying programme. A sample of 1254 students was achieved. Professional identity was measured using an adaptation of a previously described scale. Our findings suggest that a degree of professional identity is evident before students begin their training. Differences in strength of initial professional identity were observed across professions, with physiotherapy students displaying the highest levels of professional identification. To test for associations between professional identity and a number of independent variables, an ordinary least squares (OLS) regression model was estimated. The variables that were found to be significant predictors of baseline professional identity were: gender; profession; previous work experience in H&SC environments; understanding of team working; knowledge of profession; and cognitive flexibility. Some explanations for these findings are presented and the implications are discussed
