Abstract
This Letter reports the first scientific results from the observation of antineutrinos emitted by fission products of ^{235}U at the High Flux Isotope Reactor. PROSPECT, the Precision Reactor Oscillation and Spectrum Experiment, consists of a segmented 4 ton ^{6}Li-doped liquid scintillator detector covering a baseline range of 7-9 m from the reactor and operating under less than 1 m water equivalent overburden. Data collected during 33 live days of reactor operation at a nominal power of 85 MW yield a detection of 25 461±283 (stat) inverse beta decays. Observation of reactor antineutrinos can be achieved in PROSPECT at 5σ statistical significance within 2 h of on-surface reactor-on data taking. A reactor model independent analysis of the inverse beta decay prompt energy spectrum as a function of baseline constrains significant portions of the previously allowed sterile neutrino oscillation parameter space at 95% confidence level and disfavors the best fit of the reactor antineutrino anomaly at 2.2σ confidence level.

Abstract
Factor XIII (FXIII) is a plasma clotting protein involved in clot stabilization. Severe FXIII deficiency may present with severe, even fatal bleeding. Critically however, routine coagulation assays may be normal and only specific FXIII assays will detect the abnormality. Herein we discuss a case report of a patient with acquired FXIII deficiency in order to highlight the clinical challenges associated with establishing the diagnosis and discuss the treatment approach. A 70-year-old man presented with a gluteal haematoma despite no preceding personal history of bleeding. Extensive initial haemostatic investigations were normal until a specific FXIII assay showed a marked reduction in FXIII levels. With directed treatment, bleeding episodes ceased and remission was achieved. Clinical awareness of FXIII deficiency is important, so appropriate testing can be implemented in patients with unexplained bleeding diatheses, particularly those in whom bleeding responds poorly to standard replacement therapy.

Abstract
Evidence shows that surgery for severe obesity in adults improves health and psychological functioning, and is cost-effective. Data on bariatric surgery for adolescents with severe obesity are extremely limited, with no evidence on cost-effectiveness. We evaluated the lifetime cost-effectiveness of bariatric surgery compared with no surgery in adolescents with severe obesity from the UK's National Health Service perspective. Eighteen adolescents with body mass index ≥40 kg m-2 who underwent bariatric surgery (laparoscopic Roux en Y Gastric Bypass [RYGB] [N = 9], and laparoscopic Sleeve Gastrectomy [SG] [N = 9]) at University College London Hospitals between January 2008 and December 2013 were included. We used a Markov cohort model to compare the lifetime expected costs and quality-adjusted life years (QALYs) between bariatric surgery and no surgery. Mean cost of RYGB and SG procedures were £7100 and £7312, respectively. For RYGB vs. no surgery, the incremental cost/QALY was £2018 (95% CI £1942 - £2042) for males and £2005 (95% CI £1974 - £2031) for females. For SG vs. no surgery, the incremental cost/QALY was £1978 (95% CI £1954 - £2002) for males and £1941 (95% CI £1915 - £1969) for females. Bariatric surgery in adolescents with severe obesity is cost-effective; it is more costly than no surgery however it markedly improved quality of life.

Abstract
OBJECTIVE To assess the numbers of obese children and young people (CYP) eligible for assessment and management at each stage of the childhood obesity pathway in England. DESIGN Pathway modelling study, operationalising the UK National Institute for Health and Care Excellence guidance on childhood obesity management against national survey data. SETTING Data on CYP aged 2-18 years from the Health Survey for England 2006 to 2013. MAIN OUTCOME MEASURES Clinical obesity (body mass index (BMI) >98th centile), extreme obesity (BMI ≥99.86th centile); family history of cardiovascular disease or type 2 diabetes; obesity comorbidities defined as primary care detectable (hypertension, orthopaedic or mobility problems, bullying or psychological distress) or secondary care detectable (dyslipidaemia, hyperinsulinaemia, high glycated haemoglobin, abnormal liver function). RESULTS 11.2% (1.22 million) of CYP in England were eligible for primary care assessment and for community lifestyle modification. 2.6% (n=283 500) CYP were estimated to be likely to attend primary care. 5.1% (n=556 000) were eligible for secondary care referral. Among those aged 13-18 years, 8.2% (n=309 000) were eligible for antiobesity drug therapy and 2.4% (90 500) of English CYP were eligible for bariatric surgery. CYP from the most deprived quintile were 1.5-fold to 3-fold more likely to be eligible for obesity management. CONCLUSIONS There is a mismatch between population burden and available data on service use for obesity in CYP in England, particularly among deprived young people. There is a need for consistent evidence-based commissioning of services across the childhood obesity pathway based on population burden.

Abstract
OBJECTIVE Bariatric surgery is the most effective intervention for weight loss and obesity-related comorbidities currently available. Little is known about adolescents entering National Health Service (NHS) bariatric programmes. We aimed to characterise those entering a pathway and report their outcomes. DESIGN Prospective service evaluation of patients assessed within a single NHS adolescent bariatric service. RESULTS 50 patients assessed between 26 July 2007 and 27 January 2014; 6 (12%) were not eligible for surgery, 7 (14%) actively opted out, 8 (16%) were lost to follow-up and 29 (58%) underwent surgery (18 sleeve gastrectomy (SG) 11 Roux-en-y gastric bypass (RYGB) and 0 adjustable gastric band). Mean (SD) age at initial assessment was 16.0 (1.3) years and 18.3 (1.3) at surgery (youngest 15.7 years). Mean time taken to surgery was 1.8 years; longer in those with higher body mass index (BMI) and aged below 14 at first assessment. Mean (SD) BMI at surgery was 53.1 (8.3) kg/m2, lower in those undergoing RYGB (-5.2, 95% CI -11.6 to 1.13). Follow-up was inconsistent and challenging; 1/29 (3.5%) was transferred to a regional centre, 10/29 (34.5%) attended ongoing follow-up within our protocol, 6/29 (20.7%) had intermittent monitoring and 12/29 (41.4%) were lost to follow-up. Mean BMI change at 1 year (-14.0 kg/m2) and complications were similar to published cohorts. Data from 11 lost to follow-up were obtained and outcomes appeared similar to those who actively followed up. CONCLUSION Adolescent bariatric surgery in the NHS appears effective, with outcomes similar to those reported internationally. Further work is needed to optimise postsurgical surveillance and reduce age at surgery.

Abstract
BACKGROUND There is marked variation in diabetes outcomes for children and adolescents across the UK. We used modelling techniques to examine the independent contributions of deprivation, ethnicity, insulin pump use, and health service use on HbA1c trajectories across adolescence. METHODS Prospective data from a large UK Paediatric & Adolescent Diabetes Service on subjects with type 1 diabetes (T1D) aged 9-17 years from January 2008 to December 2013: 2560 HbA1c datapoints were available on 384 patients [193 (50.4%) female]. Sequential multilevel growth models assessed the effects of sex, duration of diabetes, deprivation, ethnicity, insulin pump use, and health service use on HbA1c . Growth mixture models were used to identify discrete HbA1c trajectories across adolescence. RESULTS Mean clinic HbA1c decreased from 2008 to 2013 by 0.122% (95% confidence interval: 0.034, 0.210; P = .007) per year. The optimal multilevel growth model showed mean HbA1c increased with age (B = 0.414, P < .0001), and that mean HbA1c was predicted by white/British ethnicity (B = -0.748, P = .004), clinic visits (B = 0.041, P = .04), and pump use (B = -0.568, P < .0001) but not deprivation. The optimal mixture model was a four trajectory group solution, with 45.1% in Good Control, 39.6% with Deteriorating Control, 6.5% with Rapidly Deteriorating Control, and 8.8% in Poor Control across adolescence. Only pump use predicted trajectory group membership, being protective against membership of all other trajectories compared with Good Control. CONCLUSIONS Increasing uptake of insulin pumps and ensuring access to health services are likely to be the most effective means of reducing inequalities in outcomes of T1D in children and young people.

Abstract
INTRODUCTION Prior to the introduction of viral inactivation of factor concentrates and screening of blood, 225 people with haemophilia became infected with hepatitis C (HCV) in Ireland. AIM Our aim was to assess liver disease progression and mortality in this population after 30 years of infection. METHODS Demographic and clinical data were collected from medical records in five hepatology units and one infectious disease unit retrospectively in 2005, and on four subsequent occasions. RESULTS The participation rate was 73% (165/225). Eighty three percent of patients, who had been tested for RNA (n = 106/128), developed chronic HCV infection. Thirty four percent were co-infected with HIV. All-cause mortality, after approximately 30 years of infection with chronic HCV, was 44% in HIV positive patients and 29% in HIV negative patients. Liver-related mortality was 12.5% and did not vary significantly by HIV status. Thirty seven percent of patients had developed advanced liver disease, including 20% with cirrhosis and 9% with hepatocellular carcinoma. In the pre-interferon-free direct acting antivirals era, 57% (n = 60/106) of patients were treated for HCV, 65% of whom achieved a sustained virological response. Successfully treated patients had few adverse liver outcomes. CONCLUSION After 30 years of infection, 40% of the patients who had evidence of chronic HCV had developed advanced liver disease, such as cirrhosis and HCC, or had died from liver-related causes. This proportion is high relative to similar international cohorts despite good anti-HCV treatment uptake and responses.

Abstract
BACKGROUND Tobacco (Nicotiana tabacum) is an important plant model system that has played a key role in the early development of molecular plant biology. The tobacco genome is large and its characterisation challenging because it is an allotetraploid, likely arising from hybridisation between diploid N. sylvestris and N. tomentosiformis ancestors. A draft assembly was recently published for N. tabacum, but because of the aforementioned genome complexities it was of limited utility due to a high level of fragmentation. RESULTS Here we report an improved tobacco genome assembly, which, aided by the application of optical mapping, achieves an N50 size of 2.17 Mb and enables anchoring of 64% of the genome to pseudomolecules; a significant increase from the previous value of 19%. We use this assembly to identify two homeologous genes that explain the differentiation of the burley tobacco market class, with potential for greater understanding of Nitrogen Utilization Efficiency and Nitrogen Use Efficiency in plants; an important trait for future sustainability of agricultural production. CONCLUSIONS Development of an improved genome assembly for N. tabacum enables what we believe to be the first successful map-based gene discovery for the species, and demonstrates the value of an improved assembly for future research in this model and commercially-important species.

Abstract
Type 2 diabetes in adolescence manifests as a severe progressive form of diabetes that frequently presents with complications, responds poorly to treatment, and results in rapid progression of microvascular and macrovascular complications. Although overall still a rare disease, adolescent type 2 diabetes now poses major challenges to paediatric and adult diabetes services in many countries. Therapeutic options are heavily curtailed by a dearth of knowledge about the condition, with low numbers of participants and poor trial recruitment impeding research. Together with lifestyle modification, metformin remains the first-line therapy for adolescents with type 2 diabetes, although the majority rapidly progress to treatment failure and insulin therapy. Early bariatric surgery is controversial but has great potential to transform outcomes. Health systems must respond by both concentrating patients in specialist clinical services integrated with translational research programmes, but also by joining up with local health and social care services to improve engagement and uptake of services.

Abstract
OBJECTIVES Antiobesity drug (AOD) prescribing in children and young people (CYP) in primary care is rising with high rates of discontinuation. Little is known about prescribing in this group in terms of patient demographics and comorbidities, reasons for initiation and discontinuation, or adherence to national guidelines. DESIGN Questionnaire survey to general practitioners (GPs) identified using a nationally representative primary care database covering 6% of UK population. SETTING UK-wide primary care. PARTICIPANTS Patients were eligible if prescribed an AOD aged ≤18 years between 2010 and 2012. A total of 151 patients from 108 unique practices were identified via national prescribing database, with responses for 119 patients (79%) from 84 practices; 94 of 119 (79%) were eligible for inclusion. PRIMARY AND SECONDARY OUTCOMES Survey of GP prescribing habits of AODs to CYP. We audited orlistat usage against the National Institute for Health and Care Excellence (NICE) guidance. RESULTS 47% were prescribed metformin, 59% orlistat and 5% both drugs. Orlistat was largely prescribed by GPs independently (49/55 prescriptions, 89%) and metformin by GPs on specialist recommendation (12/44, 27%). Orlistat was largely prescribed in those over 16 years of age without physical comorbidities. Metformin was initiated for treatment of polycystic ovarian syndrome (70%), insulin resistance (25%) and impaired glucose control (9%). Median supply of metformin was 10.5 months (IQR 4-18.5 months) and 2.0 months (1.0-4.0) for orlistat (p≤0.001). Drug terminations were largely due to families not requesting repeat prescriptions. NICE guidance adherence was low; 17% of orlistat prescriptions were initiated by specialists, and 56% had evidence of obesity-related comorbidity. GPs reported lower confidence in prescribing AOD to CYP compared with adults (10-point Likert score median 3 vs 8, p<0.001). CONCLUSIONS Prescribing of AOD in primary care is challenging with low adherence to NICE guidance. Further work is needed to better support GPs in the use of AOD in CYP.

Abstract
The objective of this work was to assess the effects of age and gastrointestinal location (rumen vs. colon) on bacterial community diversity and composition, as well as short-chain fatty acid profiles of preruminant male Holstein calves on an intensive milk replacer feeding program. Thirty-two calves were fed at 2% of their body weight (dry matter basis) from d 10 until harvest. Sixteen calves were euthanized at 2wk and another 16 at 4wk of age to collect digesta samples from the rumen and colon. The rumen and colon bacterial communities of preruminant calves showed a similar degree of diversity (i.e., Shannon index) whereas composition differed considerably. The colonic bacterial population was characterized by dominance of lactic acid bacteria such as Lactobacillus, Streptococcus, Enterococcus, and Bifidobacterium. In addition, colonic short-chain fatty acid and lactic acid concentrations were between 50 and 850% higher than in the rumen, indicating greater fermentative activity in the colon. On the other hand, in the rumen, no genus over-dominated and more variation was present among calves. Because of an active reticular groove and low starter grain intake during the first 1 to 3wk of life, ruminal fermentation may not contribute to significant metabolizable energy supply until after 4wk of life in intensively fed calves. Until then, calf hindgut fermentation, characterized by high abundance of lactic acid bacteria along with increased lactate and butyrate concentrations, could be beneficial for intestinal health and survival of the calf during the first weeks of life.

Abstract
BACKGROUND Law is increasingly involved in clinical practice, particularly at the end of life, but undergraduate and postgraduate education in this area remains unsystematic. We hypothesised that attitudes to and knowledge of the law governing withholding/withdrawing life-sustaining treatment from adults without capacity (the WWLST law) would vary and demonstrate deficiencies among medical specialists. AIMS We investigated perspectives, knowledge and training of medical specialists in the three largest (populations and medical workforces) Australian states, concerning the WWLST law. METHODS Following expert legal review, specialist focus groups, pre-testing and piloting in each state, seven specialties involved with end-of-life care were surveyed, with a variety of statistical analyses applied to the responses. RESULTS Respondents supported the need to know and follow the law. There were mixed views about its helpfulness in medical decision-making. Over half the respondents conceded poor knowledge of the law; this was mirrored by critical gaps in knowledge that varied by specialty. There were relatively low but increasing rates of education from the undergraduate to continuing professional development (CPD) stages. Mean knowledge score did not vary significantly according to undergraduate or immediate postgraduate training, but CPD training, particularly if recent, resulted in greater knowledge. Case-based workshops were the preferred CPD instruction method. CONCLUSIONS Teaching of current and evolving law should be strengthened across all stages of medical education. This should improve understanding of the role of law, ameliorate ambivalence towards the law and contribute to more informed deliberation about end-of-life issues with patients and families.

Abstract
The psychological and social outcomes of bariatric surgery in adolescents, together with psychological and social predictors of success, were systematically reviewed. PubMed, EMBASE, ISI Web of Science and PsychInfo were searched on July 2014. Existing data were sparse; 15 were suitable for qualitative review and six for meta-analysis (four quality of life [QOL], two depression). One study was a randomized controlled trial. A total of 139 subjects underwent Roux-en-Y gastric bypass, 202 underwent adjustable gastric band and 64 underwent sleeve gastrectomy. Overall QOL improved after bariatric surgery, regardless of surgical type with peak improvement at 6-12 months. Meta-analysis of four studies showed changed in overall QOL at latest follow-up of 2.80 standard deviation (SD) (95% confidence interval [CI] 1.23-4.37). Depression improved across all studies, regardless of procedure (effect size -0.47 SD [95% CI -0.76, -0.18] at 4-6 months). Two cohorts reported changes in both overall QOL and depression following a quadratic trajectory, with overall improvement over 2 years and deterioration in the second post-operative year. There were limited data on other psychological and social outcomes. There were insufficient data on psychosocial predictors of outcome to form evidence-based recommendations for patient selection for bariatric surgery at this time.

Abstract
OBJECTIVE To explore the acceptability of implementing an online tool for the assessment and management of childhood obesity (Computer-Assisted Treatment of CHildren, CATCH) in primary care. DESIGN AND SETTING An uncontrolled pilot study with integral process evaluation conducted at three general practices in northwest London, UK (November 2012-April 2013). PARTICIPANTS Families with concerns about excess weight in a child aged 5-18 years (n=14 children). INTERVENTION Families had a consultation with a doctor or nurse using CATCH, which assessed child weight status, cardiometabolic risk and risk of emotional and behavioural difficulties and provided personalised lifestyle advice. Families and practitioners completed questionnaires to assess the acceptability and usefulness of the consultation, and participated in semistructured interviews which explored user experiences. OUTCOME MEASURES The primary outcome was family satisfaction with the tool-assisted consultation. Secondary outcomes were practitioners' satisfaction, and acceptability and usefulness of the intervention to families and practitioners. RESULTS The majority of families (86%, n=12) and all practitioners (n=4) were satisfied with the consultation. Participants reported that the tool was easy to use, the personalised lifestyle advice useful and the use of visual aids beneficial. Families and practitioners identified a need for practical, structured support for weight management following the consultation. CONCLUSIONS The results of this pilot study indicate that an online tool for assessment and management of childhood obesity can be implemented in primary care, and is acceptable to patients, families and practitioners. Further development and evaluation of the tool is warranted.
