Abstract
The high prevalence of childhood obesity has led to questions about the influence of 'obesogenic' environments on children's health. Public health interventions targeting the retail food environment around schools have been proposed, but it is unclear if they are evidence based. This systematic review investigates associations between food outlets near schools and children's food purchases, consumption and body weight. We conducted a keyword search in 10 databases. Inclusion criteria required papers to be peer reviewed, to measure retailing around schools and to measure obesity-related outcomes among schoolchildren. Thirty papers were included. This review found very little evidence for an effect of the retail food environment surrounding schools on food purchases and consumption, but some evidence of an effect on body weight. Given the general lack of evidence for association with the mediating variables of food purchases and consumption, and the observational nature of the included studies, it is possible that the effect on body weight is a result of residual confounding. Most of the included studies did not consider individual children's journeys through the food environment, suggesting that predominant exposure measures may not account for what individual children actually experience. These findings suggest that future interventions targeting the food environment around schools need careful evaluation.

Abstract
Abstract
The Breast Cancer Campaign Tissue Bank (BCCTB) was initiated in 2010 after the charity Breast Cancer Campaign heard from breast cancer experts that insufficient high quality breast cancer tissue was preventing research which would impact people with breast cancer1. The charity decided to involve patient advocates in the development of the BCCTB from the beginning.
Two advocates reviewed the initial applications to form the BCCTB. These included both single and multi-centre applications so they suggested that, rather than choosing one centre to form the Bank, the charity consider a collaboration of centres. Throughout the development of the BCCTB, the patient advocates asked the ‘elephant in the room’ questions and brought a different perspective. They also helped to design the Bank's processes, including the consent process and asking that all tissue applicants produce a lay summary of their research.
There are now two advocates on the Board which provides strategic direction to the BCCTB. The advocates have equal status to other Board members. There are also three advocates on the Tissue Access Committee which controls the use of tissue in the Bank. Lay summaries of projects have to be approved by all advocates before an application can proceed. This means that no precious tissue is released without the approval of a lay person, who can ensure maximum patient benefit will be achieved from any research. The Bank's data return policy was also driven by the patient advocates who were keen that the tissues donated were used to their maximum benefit. This has resulted in the first publication from BCCTB2
Patient advocates have been involved in promoting the use of tissue from the bank presenting at conferences and at BCCTB road shows. Patient advocates have also been involved in asking potential donors to consent to donate to the tissue bank.
The involvement of patient advocates in the development and oversight of the BCCTB has shown researchers that patient and public involvement works. The advocates can also help promote the Bank and the benefits of tissue donation to both professionals and lay groups.
The patient advocates involved in the Breast Cancer Campaign Tissue Bank are members of the charity Independent Cancer Patients’ Voice

Abstract
Abstract
Background: Breast cancer (BC) is less common in young women (defined here as ≤ 40 years age), but is associated with more aggressive biological features, higher risk of local recurrence (LR) and poorer overall survival. This study examines and compares the incidence of LR following breast conservation therapy (BCT) versus mastectomy in women with operable BC treated at our centre.
Methods: The POWCC breast cancer database was retrospectively reviewed for the period January 1995 to December 2008. 2250 eligible women with BC undergoing primary breast surgery were identified. LR rate was compared between young women and older women (age > 40 years), and according to type of surgery. Data were analysed using a competing risk Cox model to account for distant recurrence and death as competing events for local recurrence.
Results: Median follow-up was 70 months. Of 2250 women, 246 (11%) were young women, and the mastectomy rate was 49.2%. In older women (89%), mastectomy rate was 41.7%. LR occurred in 17 (6.9%) and 57 (2.8%) in young and older women respectively (p = 0.001). Amongst the young women, 12 (9.6%) and 5 (4.1%) patients recurred locally in BCT and mastectomy respectively (p = 0.09). Amongst the older women, 43 (3.7%) and 14 (1.7%) patients recurred locally in BCT and mastectomy respectively (p = 0.008). In univariate Cox analysis, significant risk factors for LR were BCT (p = 0.003), positive surgical margins (p = 0.03), age ≤ 40 years (p = 0.001), premenopausal status (p = 0.003) and no adjuvant systemic therapy (0.02). Age remains a significant predictor of LR in multivariate Cox analysis (Table). There was no significant interaction between age and type of surgery on LR (p = 0.72).
Discussion: Our results demonstrate that young women who undergo BCT have the highest risk of early LR. Adjuvant systemic therapy is protective of early LR. This study is hypothesis-generating and a definitive prospective clinical trial is required to better determine the optimal type of breast surgery in young women.

Abstract
AIM Colorectal cancer patients identified with indeterminate pulmonary nodules (IPN) in the absence of other metastasis represent a clinical dilemma. This study aimed to identify characteristics that could predict which nodules truly represented a metastasis in an attempt to optimize therapy and to reduce the number of follow-up chest CT scans performed. METHOD All patients with colon or rectal cancer who presented between 2004 and 2008 were analysed. Patients with IPN on staging CT were identified from a dedicated prospective database and the medical records analysed and follow up recorded. Patients with obvious metastatic disease were excluded from analysis. Association of location, number and size of the nodules and metastatic disease were the primary end-points for analysis. RESULTS Nine hundred and eight patients presenting with cancer of the colon or rectum were identified. Thirty-seven (4%) patients were diagnosed with IPN with no obvious metastatic disease on staging CT. At a median follow up of 23 months there were eight (21%) cases where nodules had progressed. No significant association was detected between nodule size and pulmonary metastasis. Half of the patients with four or more nodules showed progression on serial CT imaging suggestive of pulmonary metastasis (χ(2), P ≤ 0.01). CONCLUSION Colorectal cancer patients with four or more indeterminate pulmonary nodules on preoperative staging CT imaging, even in the absence of metastasis elsewhere, are likely to represent pulmonary metastatic disease. These patients should be followed up with short-term interval CT imaging to enable early detection of progression so that treatment can be tailored appropriately.

Abstract
Acquiring the behavioral significance of sound has repeatedly been shown to correlate with long term changes in response properties of neurons in the adult primary auditory cortex. However, the molecular and cellular basis for such changes is still poorly understood. To address this, we have begun examining the auditory cortical expression of an activity-dependent effector immediate early gene (IEG) with documented roles in synaptic plasticity and memory consolidation in the hippocampus: Arc/Arg3.1. For initial characterization, we applied a repeated 10 min (24 h separation) sound exposure paradigm to determine the strength and consistency of sound-evoked Arc/Arg3.1 mRNA expression in the absence of explicit behavioral contingencies for the sound. We used 3D surface reconstruction methods in conjunction with fluorescent in situ hybridization (FISH) to assess the layer-specific subcellular compartmental expression of Arc/Arg3.1 mRNA. We unexpectedly found that both the intranuclear and cytoplasmic patterns of expression depended on the prior history of sound stimulation. Specifically, the percentage of neurons with expression only in the cytoplasm increased for repeated versus singular sound exposure, while intranuclear expression decreased. In contrast, the total cellular expression did not differ, consistent with prior IEG studies of primary auditory cortex. Our results were specific for cortical layers 3-6, as there was virtually no sound driven Arc/Arg3.1 mRNA in layers 1-2 immediately after stimulation. Our results are consistent with the kinetics and/or detectability of cortical subcellular Arc/Arg3.1 mRNA expression being altered by the initial exposure to the sound, suggesting exposure-induced modifications in the cytoplasmic Arc/Arg3.1 mRNA pool.

Abstract
Immune mediated keratopathies (IMMKs) are a relatively commonly occurring group of heterogeneous corneal disorders. This paper describes the currently recognised clinical presentations of the IMMKs in the USA and in the UK. Although a clinical diagnosis is relatively straightforward in most cases, the specific aetiopathogeneses of the IMMKs remains elusive and largely speculative, but are thought to be based upon upregulated immunoreactivity in the normally immunologically passive cornea. Treatment protocols, both medical and surgical, are based primarily on collective clinical experience and are variably successful, and in some cases recurrence or refractoriness to treatment is possible.

Abstract
The effectiveness of restraint and seclusion interventions in the nursing management of disturbed and aggressive clients remains questionable. Considerable debate continues regarding the use of these treatment options in psychiatric hospitals. The existing literature suggests that the controversial nature of restraint and seclusion creates a complex dilemma for nurses, which initiates emotional distress. This study specifically explored the emotions and feelings experienced by a group of psychiatric nurses working in Ireland in relation to incidents of restraint and seclusion. A qualitative research approach was employed incorporating focus group discussions. A total of 23 nurses participated in three focus group interviews. The data were analysed using qualitative interpretive analysis. Three themes were created consisting of: (1) the last resort - restraint and seclusion; (2) emotional distress; and (3) suppressing unpleasant emotions. It is suggested that the nurses' experience of restraint and seclusion created a dynamic movement between the release and suppression of distressing emotions. The oscillatory characteristics embedded within the nurses' emotional responses were reminiscent of a model of suffering developed by Morse in 2001. Consequently, this model is incorporated throughout the discussion of the findings to provide a more in-depth description of the emotional distress experienced by the nurses in the study.

Abstract
Two experiments were conducted to assess effects of endophyte treatments (Exp. 1), forage species (Exp. 2), and supplementation (Exp. 2) on urea production, excretion, and recycling in beef steers. Infusion of (15,15)N-urea and enrichment of urea in urine samples were used to calculate urea-N entry and recycling to the gut. Acceptably stable enrichment of (15)N-urea in urine was obtained after 50 h of intrajugular infusion of (15,15)N-urea, indicating that valid data on urea metabolism can be obtained from steers fed forages twice daily. After adjustment by covariance for differences in N intake among treatments in Exp. 1, steers fed endophyte-infected tall fescue had less (P<0.10) urea-N entry, recycling to the gut, and return of recycled urea-N to the ornithine cycle than those fed endophyte-free or novel endophyte-infected tall fescue. However, urea-N urinary excretion or return to the gut was similar among endophyte treatments when expressed as a proportion of urea-N entry. Urea-N entry and return to the gut in Exp. 2 was similar in steers fed gamagrass or orchardgrass hay after adjustment by covariance for differences in N intake. Less (P<0.01) urinary excretion, expressed as grams per day or as a proportion of urea-N entry, with gamagrass than with orchardgrass was associated with faster in vitro NDF-N digestion with gamagrass. Supplementation of gamagrass or orchardgrass with 1.76 kg/d of readily fermentable fiber and starch decreased urea entry (P<0.06) and urinary excretion of urea (P<0.01). Interactions between hay source and supplement reflected a greater response to supplementation for steers fed orchardgrass than for those fed gamagrass. After adjustment for differences among treatments in N supply, results of both experiments support the concept of improved N use in response to increased carbohydrate fermentability in the rumen, due either to inherent differences in forage fiber or to supplementation with readily fermentable carbohydrate (starch or fiber). Closer coordination of ruminal fermentation of carbohydrate and N sources provided greater and more efficient capture of dietary N as tissue protein in forage-fed steers.

Abstract
A postgraduate programme is developed to provide Family Medicine training to practising General Practitioners. The programme provides physicians with didactic material by distance education while enhancing clinical competence through face-to-face sessions in ambulatory clinics. Assessment of participating physicians is based on the responses to distance education assignments, case presentations during clinical sessions, clinical examinations at the end of year 2 and the defense of a research project in year 3. Initial programme evaluations demonstrate that the distance education format is successfully incorporated in the discipline of Family Medicine postgraduate training.

Abstract
A Pre-hospital Emergency Medical Service (PHEMS) is a vital component of a country's health service because it provides early medical care to critically ill and injured persons in the field There is evidence to show that early care reduces mortality and morbidity and offers the patient the best chance of survival and improved quality of life. Caribbean territories have been developing their PHEMS as part of a programme of health sector reform. In a study of PHEMS in 12 Caribbean countries, the Pan American Health Organization reported that there were no clear guidelines with respect to the roles and responsibilities of the physician in PHEMS in the majority of countries. In fact, a few countries had services where there was no direct physician involvement. We present a brief review of the internationally recognized roles and responsibilities of physicians in PHEMS, and make recommendations with particular reference to the Caribbean. We suggest that there is a need for direct and active involvement of physicians in the development of PHEMS because the Emergency Medical Technician is recognized as an extension of the physician in the field and is supposed to be protected by the physician's licence to deliver medical care.

Abstract
OBJECTIVES Assessment of safety skills performance and knowledge, to evaluate the education offered by the Lifeskills "Learning for Living" village, Bristol, UK which emphasizes interactive learning-by-doing. DESIGN Two quasi-experimental matched control group studies. Study 1: knowledge and performance three months post-intervention. Study 2: knowledge pre-intervention and post-intervention at three time points, to distinguish between immediate learning and longer term retention. SETTING The Lifeskills training village, Bristol, UK; primary schools in four education authorities in the area. PARTICIPANTS Study 1: 145 children aged 10-11 years; 109 from the Lifeskills program, 36 control. Study 2: 671 children aged 10-11 years; 511 Lifeskills, 160 control. OUTCOME MEASURES Three areas (road, home, and fire safety). Five performance tests: observation of children's safety skills. Five knowledge tests: pictorial quiz. RESULTS Study 1: Lifeskills/intervention children did better than control children on performance and knowledge tests. The knowledge-performance correlation was r = 0.51. Study 2: intervention children did better than control children immediately after the intervention and three months later on all five knowledge tests. On three tests the intervention group showed retention of knowledge from immediately post-intervention to three months, but on two tests there was some loss. This loss was primarily among children from scholastically lower achieving schools. In all other respects the intervention was equally successful for boys and girls, and for children from higher and lower achieving schools. CONCLUSIONS The Lifeskills package improved both knowledge and performance but had shortcomings. Complexity of material did not affect knowledge acquisition but did affect its retention.
