Transfusion Camp: The UK experience and its value in improving knowledge of transfusion medicine among postgraduate trainees

Objectives: To report the UK experience of rolling out Transfusion Camp. Background: Transfusion Camp is a structured education programme developed in Toronto, with the aim of reducing knowledge gaps in transfusion medicine in postgraduate trainees. It consists of didactic lectures viewed online by the participants, then interactive, locally delivered seminars. Since 2015, it has been rolled out in the United Kingdom, and is now available in four centres. Here, we report the UK experience of Transfusion Camp and outcomes. Methods: Trainees are recruited via the training programme directors in each region. Pre‐ and post‐course assessments are administered using the validated BEST (Biomedical Excellence for Safer Transfusion) test, with possible scores 0–20, and confidence measured on an A‐E Likert scale. Results: Since 2015, 130 trainees have participated in Transfusion Camp in the United Kingdom. Trainees from all specialties significantly improved their BEST‐test scores after attending the course (mean score 11.6/20 before the course, compared with 14.3/20 after the course), and confidence in managing transfusion‐related issues was also significantly improved. Conclusion: We recommend that all centres consider offering Transfusion Camp to trainees in haematology and other specialties that frequently use blood transfusions, such as anaesthesia/ICU, Internal Medicine and others

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

Raising awareness to prevent, recognise and manage acute pain during caesarean delivery ::the French Practice Bulletin

The incidence of acute pain during caesarean section varies between studies, with a reported rate ranging between 0.5%–17% for spinal anaesthesia and 1.7%–20% for epidural anaesthesia. Leaders from the French Club anesthésie-réanimation en obstétrique (CARO) convened to provide a clinical framework and practice bulletin to prevent, recognise and treat acute pain during caesarean section. First, a steering group agreed on 5 themes guiding quality of anaesthesia care for caesarean section: (1) appropriate neuraxial anaesthesia and testing of the surgical block prior to incision (PREVENTION); (2) appropriate organisation around decision to delivery time (COMMUNICATION); 3) appropriate management of pain before and/or after skin incision (RECOGNITION & RESPONSE); (4) appropriate prevention, identification and management of post-traumatic stress disorder (SCREENING, PREVENTION AND MANAGEMENT OF COMPLICATIONS); (5) management of medico-legal issues (MITIGATION). Then, an interdisciplinary multi-professional taskforce composed of obstetric anaesthesiologists, obstetricians, neonatologists, psychiatrists, midwifes, nurse anaesthetists, lawyers and patients, developed 23 statements that contribute to optimise care for caesarean section under neuraxial anaesthesia, of which 10 were deemed key recommendations. A decision-tree was built to optimise prevention, communication, recognition, response and management. The aim of this practice bulletin, which was endorsed by 6 societies, is to raise awareness on the risks associated with severe acute pain during caesarean section and to provide best clinical practices; pain during caesarean is not acceptable and should be prevented and managed by all stakeholders

Genome-wide association study of circulating interleukin 6 levels identifies novel loci

Interleukin 6 (IL-6) is a multifunctional cytokine with both pro- and anti-inflammatory properties with a heritability estimate of up to 61%. The circulating levels of IL-6 in blood have been associated with an increased risk of complex disease pathogenesis. We conducted a two-staged, discovery and replication meta genome-wide association study (GWAS) of circulating serum IL-6 levels comprising up to 67428 (n(discovery)=52654 and n(replication)=14774) individuals of European ancestry. The inverse variance fixed effects based discovery meta-analysis, followed by replication led to the identification of two independent loci, IL1F10/IL1RN rs6734238 on chromosome (Chr) 2q14, (P-combined=1.8x10(-11)), HLA-DRB1/DRB5 rs660895 on Chr6p21 (P-combined=1.5x10(-10)) in the combined meta-analyses of all samples. We also replicated the IL6R rs4537545 locus on Chr1q21 (P-combined=1.2x10(-122)). Our study identifies novel loci for circulating IL-6 levels uncovering new immunological and inflammatory pathways that may influence IL-6 pathobiology.Peer reviewe

The Influence of Age and Sex on Genetic Associations with Adult Body Size and Shape: A Large-Scale Genome-Wide Interaction Study.

Genome-wide association studies (GWAS) have identified more than 100 genetic variants contributing to BMI, a measure of body size, or waist-to-hip ratio (adjusted for BMI, WHRadjBMI), a measure of body shape. Body size and shape change as people grow older and these changes differ substantially between men and women. To systematically screen for age- and/or sex-specific effects of genetic variants on BMI and WHRadjBMI, we performed meta-analyses of 114 studies (up to 320,485 individuals of European descent) with genome-wide chip and/or Metabochip data by the Genetic Investigation of Anthropometric Traits (GIANT) Consortium. Each study tested the association of up to ~2.8M SNPs with BMI and WHRadjBMI in four strata (men ≤50y, men >50y, women ≤50y, women >50y) and summary statistics were combined in stratum-specific meta-analyses. We then screened for variants that showed age-specific effects (G x AGE), sex-specific effects (G x SEX) or age-specific effects that differed between men and women (G x AGE x SEX). For BMI, we identified 15 loci (11 previously established for main effects, four novel) that showed significant (FDR<5%) age-specific effects, of which 11 had larger effects in younger (<50y) than in older adults (≥50y). No sex-dependent effects were identified for BMI. For WHRadjBMI, we identified 44 loci (27 previously established for main effects, 17 novel) with sex-specific effects, of which 28 showed larger effects in women than in men, five showed larger effects in men than in women, and 11 showed opposite effects between sexes. No age-dependent effects were identified for WHRadjBMI. This is the first genome-wide interaction meta-analysis to report convincing evidence of age-dependent genetic effects on BMI. In addition, we confirm the sex-specificity of genetic effects on WHRadjBMI. These results may provide further insights into the biology that underlies weight change with age or the sexually dimorphism of body shape
