Abstract
BACKGROUND AND AIMS Evidence has shown that a positive resection margin (R1) is a key determinant of subsequent local recurrence and a poor prognostic factor in rectal cancer. The aim of this study was to evaluate the outcomes and prognosticators in patients with R1 resection of rectal cancer. MATERIAL AND METHODS Retrospective study of all patients operatively managed within our institution between April 2008 and April 2013 for rectal cancer. Baseline demographics and multiple outcome measures recorded. Overall survival (OS), disease-free survival (DFS) and recurrence were the primary outcome measures. RESULTS Overall, there were 306 primary rectal cancers. Seventy-six percent were grade T3/4 tumours. OS was 30 months. R1 rate was 16 % (48 patients). Thirty-one patients underwent APR and 17 AR. In patients who responded to neoadjuvant chemotherapy (NAC), overall survival was 55 months, with no extramural venous invasion (EMV) seen in this cohort. In non-responders OS was 29 months, with EMV in 48 %. In patients who did not receive NAC, OS was 23 months, with EMV in 74 %. EMV is a strong predictor for poor survival following R1 (p = 0.001). We also found a correlation between number of positive nodes and OS/DFS (p = 0.004). CONCLUSIONS In this small cohort of patients with R1 positive rectal cancers, response to NAC is the strongest predictor of poor overall and disease-free survival. In patients who respond to NAC, OS and DFS has been shown to be positive, with a reduced rate of EMV.

Abstract
Current guidelines on consenting individuals to participate in genomic research are diverse. This creates problems for participants and also for researchers, particularly for clinicians who provide both clinical care and research to their patients. A group of 14 stakeholders met on 7 October 2015 in Exeter to discuss the ethical issues and the best practice arising in clinically based genomic research, with particular emphasis on the issue of returning results to study participants/patients in light of research findings affecting research and clinical practices. The group was deliberately multidisciplinary to ensure that a diversity of views was represented. This report outlines the main ethical issues, areas of best practice and principles underlying ethical clinically based genomic research discussed during the meeting. The main point emerging from the discussion is that ethical principles, rather than being formulaic, should guide researchers/clinicians to identify who the main stakeholders are to consult with for a specific project and to incorporate their voices/views strategically throughout the lifecycle of each project. We believe that the mix of principles and practical guidelines outlined in this report can contribute to current debates on how to conduct ethical clinically based genomic research.

Johnson S, Kelly S, Rasali D. Differences in fall injury hospitalization and related survival rates among older adults across age, sex, and areas of residence in Canada. Inj Epidemiol 2016; 2:24.

Abstract
Background Falls are the leading cause of injury-related hospital admissions in Canadian older adults, accounting for 85 % of injury hospitalizations among older adults aged over 65 years. While many of these injuries can lead to death, the survival rates of fall-related injuries are rarely examined. This surveillance study examined the fall injury hospitalization and survival rates among older adults in the context of place. Methods Saskatchewan’s health administrative data on injury hospitalizations among individuals aged 65 years and over (n = 39,867) was utilized for this study. Variables of interest included age group, sex, and the geographical area of residence at the time of hospitalization (rural, urban, north). Logistic regression analysis was applied to determine the association of variables of interest (age group, sex, and area of residence at the time of hospitalization as the covariate) with frequency of fall injury hospitalizations. Probable time to death due to fall-related injury hospitalization was determined by survival analysis. Results Three key findings that emerged from the present study are the following: (1) fall injury hospitalizations accounted for 77 % of all injury hospitalizations; (2) fall injury hospitalization rates varied by age group, sex, and area of residence, with advancing age, women, and certain geographical areas showing higher rates; and (3) survival rates also varied by sex and area of residence. Women had longer survival estimates after a fall injury hospitalization compared to men, and those living in the north have the shortest survival estimates. Conclusions The findings from the study highlighted the high rate of fall-related injury hospitalization among older adults varying with their age group, sex, and area of residence. These factors need to be considered in injury surveillance and fall prevention research as well as programs and policies that support the reduction of falls.

Abstract
BACKGROUND Morbid obesity is an ongoing concern worldwide. There is a paucity of research reporting primary care outcomes focussed on complex and morbidly obese populations. The National Institute for Health and Care Excellence (NICE) recommends a specialist, multidisciplinary weight management team for the successful management of such populations. This is the first service evaluation reporting both primary (weight change) and secondary [body mass index (BMI), waist circumference, physical activity levels, fruit and vegetable intake, Rosenberg self-esteem score] outcomes in these patients. METHODS The present study comprised a prospective observational study of a cohort data set for patients (n = 288) attending their 3-month and 6-month (n = 115) assessment appointments at a specialist community weight management programme. RESULTS Patients had a mean (SD) initial BMI of 45.5 (6.6) kg m- ²; 66% were females. Over 80% of patients attending the service lost some weight by 3 months. Average absolute weight loss was 4.11 (4.95) kg at 3 months and 6.30 (8.41) kg at 6 months, equating to 3.28% (3.82%) and 4.90% (6.26%), respectively, demonstrating a statistically significant weight change at both time points (P < 0.001). This meets NICE best practice guidelines for the commissioning of services leading to a minimum of 3% average weight loss, with at least 30% of patients losing at ≥5% of their initial weight. Waist measurement and BMI were reduced significantly at 3 months. Improvements were also seen in physical activity levels, fruit and vegetable consumption, and self-esteem levels (P < 0.001). CONCLUSIONS This service was successful in aiding weight loss in morbidly obese populations. The findings of the present study support the view that weight-loss targets of 3% are realistic.

Abstract
The migration barriers for the vacancy-assisted migration of fission products in 3C-SiC are reported and analysed in the context of the five frequency model, which enables one to calculate an effective diffusion coefficient from elementary mechanisms. Calculations were carried out using the nudged elastic band method (NEB) with interatomic forces determined from density functional theory (DFT). Justification for treating vacancy-assisted fission product migration as limited to the FCC carbon sublattice is based on the stability of carbon vacancies, unfavourable silicon vacancy formation and the accommodation of fission products on the carbon sublattice. Results show that for most Fermi levels within the band gap the activation energy for I exceeds that of Xe which exceeds that of Kr. Results also indicate that activation energies are higher near the conduction edge, thus, implying that enhanced fission product retention can be achieved through n-type doping of 3C-SiC, which limits the availability of the migration mediating carbon vacancies.

Abstract
BACKGROUND Patients with rheumatoid arthritis (RA), including those treated with biologics, are at increased risk of some vaccine-preventable infections. We evaluated the antibody response to standard 23-valent pneumococcal polysaccharide vaccine (PPSV23) and the 2011-2012 trivalent seasonal influenza vaccine in adults with RA receiving subcutaneous (SC) abatacept and background disease-modifying anti-rheumatic drugs (DMARDs). METHODS Two multicenter, open-label sub-studies enrolled patients from the ACQUIRE (pneumococcal and influenza) and ATTUNE (pneumococcal) studies at any point during their SC abatacept treatment cycle following completion of ≥3 months' SC abatacept. All patients received fixed-dose abatacept 125 mg/week with background DMARDs. A pre-vaccination blood sample was taken, and after 28 ± 3 days a final post-vaccination sample was collected. The primary endpoint was the proportion of patients achieving an immunologic response to the vaccine at Day 28 among patients without a protective antibody level to the vaccine antigens at baseline (pneumococcal: defined as ≥2-fold increase in post-vaccination titers to ≥3 of 5 antigens and protective antibody level of ≥1.6 μg/mL to ≥3 of 5 antigens; influenza: defined as ≥4-fold increase in post-vaccination titers to ≥2 of 3 antigens and protective antibody level of ≥1:40 to ≥2 of 3 antigens). Safety and tolerability were evaluated throughout the sub-studies. RESULTS Pre- and post-vaccination titers were available for 113/125 and 186/191 enrolled patients receiving the PPSV23 and influenza vaccine, respectively. Among vaccinated patients, 47/113 pneumococcal and 121/186 influenza patients were without protective antibody levels at baseline. Among patients with available data, 73.9 % (34/46) and 61.3 % (73/119) met the primary endpoint and achieved an immunologic response to PPSV23 or influenza vaccine, respectively. In patients with pre- and post-vaccination data available, 83.9 % in the pneumococcal study demonstrated protective antibody levels with PPSV23 (titer ≥1.6 μg/mL to ≥3 of 5 antigens), and 81.2 % in the influenza study achieved protective antibody levels (titer ≥1:40 to ≥2 of 3 antigens) at Day 28 post-vaccination. Vaccines were well tolerated with SC abatacept with background DMARDs. CONCLUSIONS In these sub-studies, patients with RA receiving SC abatacept and background DMARDs were able to mount an appropriate immune response to pneumococcal and influenza vaccines. TRIAL REGISTRATION NCT00559585 (registered 15 November 2007) and NCT00663702 (registered 18 April 2008).

Abstract
The profile of brain structural abnormalities in schizophrenia is still not fully understood, despite decades of research using brain scans. To validate a prospective meta-analysis approach to analyzing multicenter neuroimaging data, we analyzed brain MRI scans from 2028 schizophrenia patients and 2540 healthy controls, assessed with standardized methods at 15 centers worldwide. We identified subcortical brain volumes that differentiated patients from controls, and ranked them according to their effect sizes. Compared with healthy controls, patients with schizophrenia had smaller hippocampus (Cohen's d=-0.46), amygdala (d=-0.31), thalamus (d=-0.31), accumbens (d=-0.25) and intracranial volumes (d=-0.12), as well as larger pallidum (d=0.21) and lateral ventricle volumes (d=0.37). Putamen and pallidum volume augmentations were positively associated with duration of illness and hippocampal deficits scaled with the proportion of unmedicated patients. Worldwide cooperative analyses of brain imaging data support a profile of subcortical abnormalities in schizophrenia, which is consistent with that based on traditional meta-analytic approaches. This first ENIGMA Schizophrenia Working Group study validates that collaborative data analyses can readily be used across brain phenotypes and disorders and encourages analysis and data sharing efforts to further our understanding of severe mental illness.

Abstract
Pre-test probability scoring and blood tests for deep venous thrombosis (DVT) assessment are sensitive but not specific leading to increased demands on radiology services. 385 patients presenting to an Emergency Department with suspected DVT were studied to explore our actual work up of patients with possible DVT relating to risk stratification, further investigation and follow up. Of the 205 patients with an initially negative scan, 36 (17.6%) were brought for review to the Emergency Department Consultant clinic. 34 (16.6%) patients underwent repeat compression ultrasound with 5 (2.4%) demonstrating a DVT on the second scan. Repeat compression ultrasound scans were performed on 34 (16.6%) of patients with an initially negative scan with essentially the same diagnostic yield as other larger studies where 100% of such patients had repeat scanning. Where there is ongoing concern, repeat above knee compression ultrasound within one week will pick up a small number of deep venous thromboses.

Abstract
Heroism is apparently nonadaptive in Darwinian terms, so why does it exist at all? Risk-taking and heroic behavior are predominantly male tendencies, and literature and legend reflect this. This study explores the possibility that heroism persists in many human cultures owing to a female preference for risk-prone rather than risk-averse males as sexual partners, and it suggests that such a preference may be exploited as a male mating strategy. It also attempts to quantify the relative influences of altruism and bravery in the evolution of heroism. Our study found that females do prefer risk-prone brave males to risk-averse non-brave males, and that men are aware of this preference. Bravery in a male was shown to be the stronger factor influencing female choice of short-term partners, long-term partners, and male friends, with altruism playing a lesser part in their choice. Altruism was deemed important in long-term relationships and friendships, but for short-term liaisons, non-altruists were preferred to altruists. Heroism may therefore have evolved owing to a female preference for brave, risk-prone males because risk-taking acts as an honest cue for "good genes." Altruism was judged to be a less influential factor in the evolution of heroism than bravery and a demonstrated willingness to take risks.
