Using an identity lens : constructive working with children in the criminal justice system

Research has shown that identity, and how you feel about yourself, can be key to moving forward with life and away from crime. Working with the University of Salford, Youth Offending Teams and supported by the Barrow Cadbury Trust, this resource has been developed to promote a constructive, identity-focused approach to ultimately help divert children away from progressing further through the criminal justice system. Using the principles of the Nacro-led Beyond Youth Custody programme, this toolkit outlines how these can be applied to working with children before custody to support them towards positive outcomes and prevent further offending

The contribution of OCTN1/2 variants within the IBD5 locus to disease susceptibility and severity in Crohn's disease

Background and Aims: Recent data suggest that polymorphisms in the organic cation transporter (OCTN) genes OCTN1 (SLC22A4) and OCTN2 (SLC22A5) represent disease-causing mutations within the IBD5 locus (chromosome 5q31). We investigated associations with disease susceptibility, phenotype, and evidence for epistasis with CARD15 in 679 patients with Crohn’s disease (CD) or ulcerative colitis (UC). Methods: A total of 374 patients with CD, 305 patients with UC, and 294 healthy controls (HCs) were studied. Genotyping for single nucleotide polymorphisms IGR2096, IGR2198, and IGR2230, OCTN1 variant (SLC22A4 1672C→T), and OCTN2 variant (SLC22A5 −207G→C) was performed using the TaqMan system. Results: The IBD5 OCTN1 and OCTN2 polymorphisms were in strong linkage disequilibrium (D′, >0.959). IGR2198 variant allele frequency (49.1% vs 40.8%; P = .0046) and homozygosity (21% vs 14.8%; P = .044) were associated with CD versus HCs. Variant allelic frequency of OCTN1 (53.6% vs 43%; P = .0008) and OCTN2 (56.1% vs 48.4%; P = .0092) polymorphisms and homozygosity for the OCTN1/2-TC haplotype (28.4% vs 16%; P = .0042) were associated with CD versus HCs. IGR2198 homozygosity and TC homozygosity were associated with stricturing/penetrating disease at follow-up (P = .011 and P = .011, respectively) and disease progression (P = .038 and P = .049, respectively) on univariate analysis and with need for surgery on multivariate analysis (P = .016 and P = .004, respectively). In the absence of the IBD5 risk haplotype, no association of OCTN1/2 variants with CD was detected. No associations were seen with UC. Conclusions: The IBD5 locus influences susceptibility, progression, and need for surgery in CD. However, the contribution of OCTN1/2 variants is not independent of the IBD5 haplotype; a causative role for these genes remains plausible but is not yet proven. Further genetic, functional, and expression data are now required. </p

Serum Calprotectin - A novel diagnostic and prognostic marker in Inflammatory Bowel Diseases

OBJECTIVES: There is an unmet need for novel blood-based biomarkers that offer timely and accurate diagnostic and prognostic testing in inflammatory bowel diseases (IBD). We aimed to investigate the diagnostic and prognostic utility of serum calprotectin (SC) in IBD. METHODS: A total of 171 patients (n=96 IBD, n=75 non-IBD) were prospectively recruited. A multi-biomarker model was derived using multivariable logistic regression analysis. Cox proportional hazards model was derived to assess the contribution of each variable to disease outcomes. RESULTS: SC correlated strongly with current biomarkers, including fecal calprotectin (FC) (n=50, ρ=0.50, P=1.6 × 10−4). SC was the strongest individual predictor of IBD diagnosis (odds ratio (OR): 9.37 (95% confidence interval (CI): 2.82–34.68), P=4.00 × 10−4) compared with other markers (C-reactive protein (CRP): OR 8.52 (95% CI: 2.75–28.63), P=2.80 × 10−4); albumin: OR 6.12 (95% CI: 1.82–22.16), P=0.004). In a subset of 50 patients with paired SC and FC, the area under receiver operating characteristic discriminating IBD from controls was better for FC than for SC (0.99, (95% CI 0.87–1.00) and 0.87 (95% CI:0.78–0.97), respectively; P=0.01). At follow-up (median 342 days; interquartile range: 88–563), SC predicted treatment escalation and/or surgery in IBD (hazard ratio (HR) 2.7, 95% CI: 1.1–4.9), in particular Crohn’s disease (CD) (HR 4.2, 95% CI 1.2–15.3). A model incorporating SC and either CRP or albumin has a positive likelihood ratio of 24.14 for IBD. At 1 year, our prognostic model can predict treatment escalation in IBD in 65% of cases (95% CI: 43–79%) and 80% (95% CI: 31–94%) in CD if ≥2 blood marker criteria are met. CONCLUSIONS: A diagnostic and prognostic model that combines SC and other blood-based biomarkers accurately predicts the inflammatory burden in IBD and has the potential to predict disease and its outcomes. Our data warrant further detailed exploration and validation in large multicenter cohorts

Health First: An evidence-based alcohol strategy for the UK

Alcohol is taken for granted in the UK today. It is easy to get hold of, increasingly affordable, advertised everywhere and accepted by many as an integral part of daily life. Yet, despite this, the great majority of the population recognise the harm that alcohol causes. They believe that drinking damages health, drives anti social behaviour, harms children and families and creates huge costs for the NHS and the Police. They are right. Every year in the UK, there are thousands of deaths and over a million hospital admissions related to drinking. More than two in five (44%) violent crimes are committed under the influence of alcohol, as are 37% of domesti c violence incidents. One fifth of all violent crime occurs in or near pubs and clubs and 45% of adults avoid town centres at night because of drunken behaviour. The personal, social and economic cost of alcohol has been estimated to be up to &pound;55bn for England and &pound;7.5bn for Scotland. None of this should be taken for granted. The impact of drinking on public health and community safety is so great that radical steps are needed to change our relationship with alcohol. We need to imagine a society where low or no alcohol consumpti on is the norm, drunkenness is socially unacceptable and town centres are safe and welcoming places for everyone to use. Our vision is for a safer, healthier and happier world where the harm caused by alcohol is minimised. This vision is achievable. But only if we tackle the primary drivers of alcohol consumption. The evidence is clear: the most effective way to reduce the harm from alcohol is to reduce the affordability, availability and attractiveness of alcohol products. It is not enough to limit the damage once people are drunk, dependent, ill or dying. We need to intervene earlier in order to reduce consumption across the entire population. The tools are available. The &lsquo;four Ps' of the marketing mix - price, product, promotion and place - are used by alcohol producers and retailers to increase their sales of alcohol. They can also be used by government to reduce alcohol sales, alcohol consumption and alcohol-related harm. Alcohol taxes are an effective public health measure as they raise prices and suppress demand. However, if they do not keep pace with both inflation and incomes, alcohol products will become more affordable over time. This has been the case in the UK. Deep discounting by retailers has also driven down the price of alcohol and encouraged heavy drinkers to maintain dangerous levels of consumption. These problems need to be tackled by a combinati on of more effective fiscal policy and controls on pricing and discounting. Alcohol products are an extraordinary anomaly. Unlike most food products, they are both remarkably harmful and excepti onally lightly regulated. As with other toxic products, the product label ought to communicate the content of the product and the risks of its consumpti on. Regulation should drive out products that appeal to young people while also incentivising the development and sale of lower strength products. The pervasive marketing of alcohol products in the UK is indefensible. Current restrictions are woefully inadequate: children and young people are regularly exposed to alcohol adverti sing in both old and new media. Only a complete ban on all alcohol advertising and sponsorship will make a lasting diff erence. Licensing practice in the UK is out of date. The focus on pubs and bars has allowed shops and supermarkets to become the dominant players in alcohol sales. Consequently, alcohol is now more available than it has ever been. This has driven pre-loading: getting drunk on cheap, shop-bought alcohol before heading out to late-opening night life. Licensing must focus on public health and seek to control the overall availability of alcohol as well as the effects of drunkenness. Beyond these populati on-level approaches, many more targeted measures are needed to reduce alcohol-related harm. Early interventi on by health and social care professionals is an important and underexploited opportunity to prevent problems developing. Stronger drink driving measures are also required. All these measures are needed. Together, they provide a template for an integrated and comprehensive strategy to tackle the harm from alcohol in the UK.Additional co-authors: Gerry McElwee, Dr Kieran Moriarty CBE, Dr Robin Purshouse, Dr Peter Rice, Alison Rogers, George Roycroft , Chit Selvarajah, Don Shenker, Eric Appleby, Dr Nick Sheron, and Colin Shevill

A Framework for Developing the Structure of Public Health Economic Models

Background: A conceptual modeling framework is a methodology that assists modelers through the process of developing a model structure. Public health interventions tend to operate in dynamically complex systems. Modeling public health interventions requires broader considerations than clinical ones. Inappropriately simple models may lead to poor validity and credibility, resulting in suboptimal allocation of resources. Objective: This article presents the first conceptual modeling framework for public health economic evaluation. Methods: The framework presented here was informed by literature reviews of the key challenges in public health economic modeling and existing conceptual modeling frameworks; qualitative research to understand the experiences of modelers when developing public health economic models; and piloting a draft version of the framework. Results: The conceptual modeling framework comprises four key principles of good practice and a proposed methodology. The key principles are that 1) a systems approach to modeling should be taken; 2) a documented understanding of the problem is imperative before and alongside developing and justifying the model structure; 3) strong communication with stakeholders and members of the team throughout model development is essential; and 4) a systematic consideration of the determinants of health is central to identifying the key impacts of public health interventions. The methodology consists of four phases: phase A, aligning the framework with the decision-making process; phase B, identifying relevant stakeholders; phase C, understanding the problem; and phase D, developing and justifying the model structure. Key areas for further research involve evaluation of the framework in diverse case studies and the development of methods for modeling individual and social behavior. Conclusions: This approach could improve the quality of Public Health economic models, supporting efficient allocation of scarce resources

Identification of novel genetic determinants in the high prevalence early-onset inflammatory bowel disease population in Scotland

Grant no. 072789/Z/03/ZBackground & aims: The inflammatory bowel diseases (IBD), Crohn‟s disease (CD) and ulcerative colitis (UC), are common causes of chronic gastrointestinal morbidity, affecting up to 1 in 250 of the general population in Northern Europe. Up to 25% of IBD is diagnosed during childhood or adolescence. The aims for this thesis were to study the epidemiology, natural history and novel genetic determinants of childhood onset IBD in Scotland. Methods: The existing repository of childhood onset and adult onset IBD patients, established at the Western General Hospital in Edinburgh, was used and expanded. Thus, anatomical location and behaviour of disease were assessed in 416 childhood onset (276 CD, 99 UC, 41 IBDU diagnosed before 17th birthday) and 1297 adult patients (596 CD, 701 UC) using the Montreal classification. Additional phenotypic (at diagnosis and at regular follow-up intervals) and epidemiological data were gathered. In this cohort, genotyping of germline variants in putative susceptibility genes (NOD1/CARD4, IL23R, ATG16L1, IRGM, FLG) was performed to enable single variant and haplotype-tagging association studies. Genotypic data of population-matched healthy controls were obtained locally (n=342) and from the Wellcome Trust Case Control Consortium (n=2937). Results: Compared with adults, childhood-onset CD was characterized by a more extensive, “panenteric” phenotype (ileocolonic plus upper GI; p<0.0001 OR23.3; 95% CI (13.4–40.6) with less isolated ileal (p<0.0001 OR 0.06 (0.03–0.1) or colonic disease (p<0.0001, OR 0.3 (0.2–0.5)). In 39%, the anatomic extent increased within 2 years. UC was also more extensive in children at diagnosis vs adults (p0.05 after Bonferroni correction). We found that the allelic frequency of rs11209026*A located within the IL23R gene, differed significantly between IBD / CD cases and controls (p=0.01 OR 0.51(0.3-0.9) and p=0.04 OR 0.5 (0.3-0.98)). Using a gene-wide haplotype-tagging strategy, we demonstrated that the multiple association signals of the IL23R locus are independent of rs11209026 in childhood onset IBD and CD. In Scottish children, the effect of germline variation of ATG16L1 and IRGM on CD susceptibility was relatively small (OR< 1.4), and appeared less than in adult disease. Genotype–phenotype analysis demonstrated an association of pure ileal disease with the ATG16L1 rs2241880G-allele (p=0.02 OR 1.3 (1.03–1.7)). Using binary logistic regression analysis, we confirmed the effect of rs2241880 genotype (GG) on ileal disease versus colonic disease (p=0.03 OR 2.4 (1.05–5.6)). Null alleles of the epithelial barrier protein FLG have no important effect on IBD susceptibility (p>0.4), but contribute to the high prevalence of atopy, notably co-existent eczema and food allergy (p=0.0003 OR 3.3 (1.7–6.6) and p=0.0001 OR 4.5 (2.0–10.0), respectively). Conclusion: Childhood onset IBD is characterised by extensive intestinal involvement and progression of disease after diagnosis. Genetic association studies in childhood and adult IBD have provided evidence for a large number of new genomic loci. These loci encode genes involved in a number of homeostatic mechanisms: innate pattern recognition receptors, the differentiation of Th17-lymphocytes, autophagy, maintenance of epithelial barrier integrity and the orchestration of the secondary immune response

Human SNP links differential outcomes in inflammatory and infectious disease to a FOXO3-regulated pathway

The clinical course and eventual outcome, or prognosis, of complex diseases varies enormously between affected individuals. This variability critically determines the impact a disease has on a patient’s life but is very poorly understood. Here, we exploit existing genome-wide association study data to gain insight into the role of genetics in prognosis. We identify a noncoding polymorphism in FOXO3A (rs12212067: T > G) at which the minor (G) allele, despite not being associated with disease susceptibility, is associated with a milder course of Crohn’s disease and rheumatoid arthritis and with increased risk of severe malaria. Minor allele carriage is shown to limit inflammatory responses in monocytes via a FOXO3-driven pathway, which through TGFβ1 reduces production of proinflammatory cytokines, including TNFα, and increases production of anti-inflammatory cytokines, including IL-10. Thus, we uncover a shared genetic contribution to prognosis in distinct diseases that operates via a FOXO3-driven pathway modulating inflammatory responses. PAPERCLIP

Analysis of Germline GLI1 Variation Implicates Hedgehog Signalling in the Regulation of Intestinal Inflammatory Pathways
