Abstract
Despite more than a century of research, the aetiology of sporadic Alzheimer's disease (AD) remains unclear and finding disease modifying treatments for AD presents one of the biggest medical challenges of our time. AD pathology is characterized by deposits of aggregated amyloid beta (Aβ) in amyloid plaques and aggregated tau in neurofibrillary tangles. These aggregates begin in distinct brain regions and spread throughout the brain in stereotypical patterns. Neurodegeneration, comprising loss of synapses and neurons, occurs in brain regions with high tangle pathology, and an inflammatory response of glial cells appears in brain regions with pathological aggregates. Inheriting an apolipoprotein E ε4 (APOE4) allele strongly increases the risk of developing AD for reasons that are not yet entirely clear. Substantial amounts of evidence support a role for APOE in modulating the aggregation and clearance of Aβ, and data have been accumulating recently implicating APOE4 in exacerbating neurodegeneration, tau pathology and inflammation. We hypothesize that APOE4 influences all the pathological hallmarks of AD and may sit at the interface between neurodegeneration, inflammation and the spread of pathologies through the brain. Here, we conducted a systematic search of the literature and review evidence supporting a role for APOE4 in neurodegeneration and inflammation. While there is no direct evidence yet for APOE4 influencing the spread of pathology, we postulate that this may be found in future based on the literature reviewed here. In conclusion, this review highlights the importance of understanding the role of APOE in multiple important pathological mechanisms in AD.

Abstract
PLAIN ENGLISH SUMMARY This paper describes the methods that were used to develop a health behaviour intervention specifically for teenage and young adult cancer survivors (TYACS). The program of work, carried out in partnership with CLIC Sargent (a UK based cancer charity for children and young people) was guided by The Behaviour Change Intervention Design Process. A systematic review of existing intervention studies was carried out and TYACS were surveyed on their interest in receiving health behaviour information and their preference regarding the format, delivery and timing of such information. Health professionals were also surveyed to gather their views on how health behaviour information would be best delivered to young people with cancer. The results of these studies informed the development of a collection of health behaviour change intervention resources containing comprehensive lifestyle information and behaviour change support tools. TYACS and TYA health professionals were invited to review and provide feedback on the relevance, appeal and usability of the resources. It is hoped that by involving TYACS and TYA representatives at every stage of intervention development the problem of low uptake and adherence commonly encountered during intervention piloting will be prevented. ABSTRACT Background Teenage and Young Adult Cancer Survivors (TYACS) are advised to adopt a healthy lifestyle in order to reduce the impact of cancer and its treatments upon their long-term health. However, at present there are no interventions available in the UK to support TYACS to lead a healthy lifestyle. To inform the development of a lifestyle intervention for TYACS a partnership was set up between academic behavioural scientists and CLIC Sargent, a cancer charity which supports children and young people. Methods A series of studies to understand patient and professionals needs and perspectives regarding health behaviour change were carried out. TYACS were surveyed to gather data on their current health behaviour status; interest in, and experience of receiving, lifestyle advice; and preference regarding the type, format, and delivery of a lifestyle intervention. Health care professionals were surveyed simultaneously to gather their views on how best to promote health behaviour change to TYACS. In this paper we summarise key findings from the development work, the resulting lifestyle intervention, and new data from a preliminary evaluation study exploring TYACS and TYA health professionals' views on the relevance, appeal and usability of the intervention resources. Results A collection of health behaviour change intervention resources containing lifestyle information and behaviour change support tools were developed. These intervention resources were well received by TYACS and health professionals with the majority rating the information as high quality, helpful and relevant. Over 80% of TYACS reported they would find the support tools 'very appealing' or 'quite appealing'. TYACS and health professionals provided feedback on how the resources could be improved including commenting that more personalized or tailored health behaviour information would be beneficial. Discussion and conclusion It is hoped that by involving TYACS and TYA representatives at every stage of intervention development,and carrying out a preliminary evaluation of the intervention resources, the problem of low uptake and adherence commonly encountered during formal intervention piloting and evaluation will be prevented.

Abstract
The dynamics of granular flow in a rectangular silo with two symmetrically placed exit openings is investigated using particle image velocimetry (PIV), flow rate measurements and discrete element modelling (DEM). The flow of mustard seeds in a Perspex silo is recorded using a high-speed camera and the resulting image frames are analysed using PIV to obtain velocity, velocity divergence and shear rate plots. A change in flow structure is observed as the distance L between the two openings is varied. The mass flow rate is shown to be at a maximum at zero opening separation, decreasing as L is increased; it then reaches a minimum before rising to an equilibrium rate close to two times that of an isolated (non-interacting) opening. The flow rate experiment is repeated using amaranth and screened sand and similar behaviour is observed. Although this result is in contrast with some recent DEM and physical experiments in silo systems, this effect has been reported in an analogous system: the evacuation of pedestrians from a room through two doors. Our experimental results are replicated using DEM and we show that inter-particle friction controls the flow rate behaviour and explains the discrepancies in the literature results.

Abstract
BACKGROUND The reason for declining risk to psychosis across individuals assessed and meeting Ultra High Risk (UHR) criteria is still unclear. No studies have investigated the potential substantial role of the underlying risk enrichment across all the individuals undergoing an UHR assessment. METHODS Cohort study including all non-psychotic subjects who were assessed on suspicion of psychosis risk by the OASIS UHR service in the period 2001 to 2015. Posttest (after UHR assessment) and pretest risk (before UHR assessment) of psychosis were stratified and compared across three time periods (2001-2005, 2006-2010, 2011-2015) with Cox analysis and modulating factors were investigated. RESULTS The posttest risk of psychosis at the OASIS service has increased from the initial pilot years of the service (2001-2005) and then stabilised and not declined over the following decade (2006-2010 and 2011-2015). This was paralleled by a similar course of pretest risk for psychosis. Stability of pretest risk for psychosis over the past decade was associated with a lack of change in ethnicity and to counterweighting changes in the type of referral sources over different time periods. CONCLUSIONS The time course of transition risk to psychosis in UHR services is strictly associated with the time course of pretest risk enrichment. If the latter remains stable over time, as for the OASIS service, no declining transition risk is observed over the most recent years. Pretest risk enrichment is determined by recruitment and sampling strategies. This study confirms the need to control these factors in the UHR field.

Abstract
Prospective epidemiological studies have consistently demonstrated that cannabis use is associated with an increased subsequent risk of both psychotic symptoms and schizophrenia-like psychoses. Early onset of use, daily use of high-potency cannabis, and synthetic cannabinoids carry the greatest risk. The risk-increasing effects are not explained by shared genetic predisposition between schizophrenia and cannabis use. Experimental studies in healthy humans show that cannabis and its active ingredient, delta-9-tetrahydrocannabinol (THC), can produce transient, dose-dependent, psychotic symptoms, as well as an array of psychosis-relevant behavioral, cognitive and psychophysiological effects; the psychotogenic effects can be ameliorated by cannabidiol (CBD). Findings from structural imaging studies in cannabis users have been inconsistent but functional MRI studies have linked the psychotomimetic and cognitive effects of THC to activation in brain regions implicated in psychosis. Human PET studies have shown that acute administration of THC weakly releases dopamine in the striatum but that chronic users are characterised by low striatal dopamine. We are beginning to understand how cannabis use impacts on the endocannabinoid system but there is much still to learn about the biological mechanisms underlying how cannabis increases risk of psychosis. This article is part of the Special Issue entitled "A New Dawn in Cannabinoid Neurobiology".

Abstract
OBJECTIVES We describe the development and validation of measures of human papillomavirus (HPV)/HPV vaccination knowledge, fear/anxiety about vaccination, involvement in HPV vaccine decision-making, and self-efficacy with regard to getting the vaccine, designed to evaluate the efficacy of an intervention to affect these domains (collectively termed the HAVIQ: HPV Adolescent Vaccine Intervention Questionnaire). STUDY DESIGN Literature search, cognitive interviews and cross-sectional survey. METHODS A literature search identified existing items that were modified for the present measures. Experts reviewed draft measures for face and content validity. Cognitive interviews with adolescents were also used to assess content validity. Adolescents completed the measures and an internal reliability analysis of each measure was performed. RESULTS The four experts concurred that the measures had face validity. Cognitive interviews identified items requiring refinement. Content validity was examined with ten experts and was deemed acceptable. There were 1800 adolescents who completed the measures; Cronbach's alpha was >0.6 for three of the four measures. The four final measures are brief, comprising 25 items in total. CONCLUSIONS The measures are robustly developed and validity-tested. The HAVIQ may be used in research settings to evaluate adolescents' knowledge and experiences of the process of HPV vaccination in a school-based vaccination programme.

Abstract
BACKGROUND/INTRODUCTION Acute kidney injury (AKI) is common in acute hospital admission and associated with worse patient outcomes. AIM To measure incidence, care quality and outcome of AKI in admitted hospital care. DESIGN Forty-six of 168 acute NHS healthcare trusts in UK caring for 2 million acute hospital admissions per annum collected information on adults identified with AKI stage 3 (3-fold rise in serum creatinine or creatinine >354 µmol/l) through routine biochemical testing over a 5-month period in 2012. METHODS Information was collected on patient and care characteristics. Primary outcomes were survival and recovery of kidney function at 1 month. RESULTS A total of 15 647 patients were identified with biochemical AKI stage 3. Case note reviews were available for 7726 patients. In 80%, biochemical AKI stage 3 was confirmed clinically. Among this group, median age was 75 years, median length of stay was 12 days and the overall mortality within 1 month was 38%. Significant factors in a multivariable model predicting survival included age and some causes of AKI. Dipstick urinalysis, medication review, discussion with a nephrologist and acceptance for transfer to a renal unit were also associated with higher survival, but not early review by a senior doctor, acceptance for transfer to critical care or requirement for renal replacement therapy. Eighteen percent of people did not have their kidney function checked 1 month after the episode had resolved. DISCUSSION/CONCLUSIONS This large study of in-hospital AKI supports the efficacy of biochemical detection of AKI in common usage. AKI mortality remains substantial, length of stay comparable with single-centre studies, and much of the variation is poorly explained (model Cox and Snell R2 = 0.131) from current predictors.

Abstract
Viticulture, like other fields of agriculture, is currently facing important challenges that will be addressed only through sustained, dedicated and coordinated research. Although the methods used in biology have evolved tremendously in recent years and now involve the routine production of large data sets of varied nature, in many domains of study, including grapevine research, there is a need to improve the findability, accessibility, interoperability and reusability (FAIR-ness) of these data. Considering the heterogeneous nature of the data produced, the transnational nature of the scientific community and the experience gained elsewhere, we have formed an open working group, in the framework of the International Grapevine Genome Program (www.vitaceae.org), to construct a coordinated federation of information systems holding grapevine data distributed around the world, providing an integrated set of interfaces supporting advanced data modeling, rich semantic integration and the next generation of data mining tools. To achieve this goal, it will be critical to develop, implement and adopt appropriate standards for data annotation and formatting. The development of this system, the GrapeIS, linking genotypes to phenotypes, and scientific research to agronomical and oeneological data, should provide new insights into grape biology, and allow the development of new varieties to meet the challenges of biotic and abiotic stress, environmental change, and consumer demand.

Abstract
BACKGROUND After emergency department (ED) discharge, Spanish-speaking patients with limited English proficiency are less likely than English-proficient patients to be adherent to medical recommendations and are more likely to be dissatisfied with their visit. OBJECTIVES To determine if integrating a longitudinal medical Spanish and cultural competency curriculum into emergency medicine residency didactics improves patient satisfaction and adherence to medical recommendations in Spanish-speaking patients with limited English proficiency. METHODS Our ED has two Emergency Medicine Residency Programs, University Campus (UC) and South Campus (SC). SC program incorporates a medical Spanish and cultural competency curriculum into their didactics. Real-time Spanish surveys were collected at SC ED on patients who self-identified as primarily Spanish-speaking during registration and who were treated by resident physicians from both residency programs. Surveys assessed whether the treating resident physician communicated in the patient's native Spanish language. Follow-up phone calls assessed patient satisfaction and adherence to discharge instructions. RESULTS Sixty-three patients self-identified as primarily Spanish-speaking from August 2014 to July 2015 and were initially included in this pilot study. Complete outcome data were available for 55 patients. Overall, resident physicians spoke Spanish 58% of the time. SC resident physicians spoke Spanish with 66% of the patients versus 45% for UC resident physicians. Patients rated resident physician Spanish ability as very good in 13% of encounters - 17% for SC versus 5% for UC. Patient satisfaction with their ED visit was rated as very good in 35% of encounters - 40% for SC resident physicians versus 25% for UC resident physicians. Of the 13 patients for whom Spanish was the language used during the medical encounter who followed medical recommendations, ten (77%) of these encounters were with SC resident physicians and three (23%) encounters were with UC resident physicians. CONCLUSION Preliminary data suggest that incorporating Spanish language and cultural competency into residency training has an overall beneficial effect on patient satisfaction and adherence to medical recommendations in Spanish-speaking patients with limited English proficiency.

Abstract
Associations between sexual risk and alcohol consumption may be self-evident but have eluded detailed examination in the UK. A cohort of 520 genitourinary (GU) medicine clinic attenders in the south of England were given a detailed questionnaire and compared with a matched cohort from the General Household Survey (GHS). Clinic attenders binged heavily –a median of 13 units on a usual night and 26 on a 'heavy' night, compared with six units in the GHS cohort. In all, 86% of clinic attenders exceeded the UK government 'binge drinking' level of six units, and 32% of subjects thought that alcohol played a role in their clinic attendance. A total of 77% had been drinking before sex with a new partner; of these, 65% were usually or occasionally very drunk. Binge drinking was increased in the 29% diagnosed with a bacterial sexually transmitted infection ( P < 0.003). Of the women, 19% reported an unwanted pregnancy, with 28% drinking beforehand.

Abstract
Objective: To investigate the effect of ankle motility on chronic venous leg ulcer healing, and to relate this to calf pump function and muscle bulk. Methods: This was a prospective cohort study undertaken in a leg ulcer clinic. Ankle motility, calf-ankle circumference ratio and calf pump power (derived from digital photoplethysmography) were assessed as to their effect on ulcer healing rate. Thirty consecutive patients undergoing multi-layer compression bandaging for open chronic venous ulcers were included. Results: Ankle motility was an independent risk factor for ulcer healing ( p = 0.001, hazard ratio 1.08, 95% CI 1.03–1.13). Ankle motility correlated with calf-ankle circumference ratio ( r = 0.48, p<0.01). No relationship was found between photoplethysmography-derived calf pump power, ankle motility or ulcer healing rate. Conclusions Ulcers in legs with poor ankle motility are slower to heal and this may be related to reduced calf muscle bulk. Ankle exercises or physiotherapy could be considered in such patients.
