    Primary biliary cirrhosis (PBC) is a classical autoimmune liver disease for which effective immunomodulatory therapy is lacking. Here we perform meta-analyses of discovery data sets from genome-wide association studies of European subjects (n=2,764 cases and 10,475 controls) followed by validation genotyping in an independent cohort (n=3,716 cases and 4,261 controls). We discover and validate six previously unknown risk loci for PBC (Pcombined<5 × 10(-8)) and used pathway analysis to identify JAK-STAT/IL12/IL27 signalling and cytokine-cytokine pathways, for which relevant therapies exist

    The genetic architecture of the human cerebral cortex

    Get PDF
    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

    Obesity in adults: a 2022 adapted clinical practice guideline for Ireland

    Get PDF
    This Clinical Practice Guideline (CPG) for the management of obesity in adults in Ireland, adapted from the Canadian CPG, defines obesity as a complex chronic disease characterised by excess or dysfunctional adiposity that impairs health. The guideline reflects substantial advances in the understanding of the determinants, pathophysiology, assessment, and treatment of obesity. It shifts the focus of obesity management toward improving patient-centred health outcomes, functional outcomes, and social and economic participation, rather than weight loss alone. It gives recommendations for care that are underpinned by evidence-based principles of chronic disease management; validate patients' lived experiences; move beyond simplistic approaches of "eat less, move more" and address the root drivers of obesity. People living with obesity face substantial bias and stigma, which contribute to increased morbidity and mortality independent of body weight. Education is needed for all healthcare professionals in Ireland to address the gap in skills, increase knowledge of evidence-based practice, and eliminate bias and stigma in healthcare settings. We call for people living with obesity in Ireland to have access to evidence-informed care, including medical, medical nutrition therapy, physical activity and physical rehabilitation interventions, psychological interventions, pharmacotherapy, and bariatric surgery. This can be best achieved by resourcing and fully implementing the Model of Care for the Management of Adult Overweight and Obesity. To address health inequalities, we also call for the inclusion of obesity in the Structured Chronic Disease Management Programme and for pharmacotherapy reimbursement, to ensure equal access to treatment based on health-need rather than ability to pay

    Negotiating the political minefield of English language arts: a critical perspective

    Get PDF
    In 2001, senior high English Language Arts (ELA) teachers in Newfoundland and Labrador witnessed the introduction of a new ELA curriculum that, to many, was viewed as a dramatic shift in theory, content, and methodology. However, a review of the history of education and the teaching of English (in Newfoundland and Labrador as well as globally) reveals that, while much remains the same, there have been continual reformulations of ELA programs since the inception of English as a subject in the nineteenth century. To better understand the most recent incarnation of the ELA program, it may be beneficial for teachers not only to review the history of English as a subject (see Chapter One) and of education in Newfoundland and Labrador (see Chapter Two) which reveal the political and ideological nature of "English teaching," but also to consider the diverse cultural, economic, and social dynamics that exist in Newfoundland and Labrador (see Chapter Three) which may provide insight about where our students are coming from, what they need, and where they hope to go. From here, an examination of current ELA Foundation and curriculum documents (see Chapter Four), which reflect the most recent modifications to the delivery of ELA programs, will uncover the remnants of earlier formulations of the subject as well as the existence of contending, and often contradictory, ideological forces that continue to influence and be influenced by the study of ELA. There are no simple answers (nor should there be) to the overwhelming problems of attempting to resolve the contradictions in the curriculum documents; to meet the needs of our students' diverse, complex, and hybrid identities; and to reconcile the contending ideological forces that pervade our classrooms. Yet, we must not concede helplessness nor plead ignorance. Facilitating awareness, in ourselves and our students, becomes the first step in meeting these challenges head on and working towards an ELA program that is more democratic and beneficial to all our students (see Chapter Five)

    Coating of biomaterial scaffolds with the collagen-mimetic peptide GFOGER for bone defect repair

    Healing large bone defects and non-unions remains a significant clinical problem. Current treatments, consisting of auto and allografts, are limited by donor supply and morbidity, insufficient bioactivity and risk of infection. Biotherapeutics, including cells, genes and proteins, represent promising alternative therapies, but these strategies are limited by technical roadblocks to biotherapeutic delivery, cell sourcing, high cost, and regulatory hurdles. In the present study, the collagen-mimetic peptide, GFOGER, was used to coat synthetic PCL scaffolds to promote bone formation in critically-sized segmental defects in rats. GFOGER is a synthetic triple helical peptide that binds to the [alpha]2[beta]1 integrin receptor involved in osteogenesis. GFOGER coatings passively adsorbed onto polymeric scaffolds, in the absence of exogenous cells or growth factors, significantly accelerated and increased bone formation in non-healing femoral defects compared to uncoated scaffolds and empty defects. Despite differences in bone volume, no differences in torsional strength were detected after 12 weeks, indicating that bone mass but not bone quality was improved in this model. This work demonstrates a simple, cell/growth factor-free strategy to promote bone formation in challenging, non-healing bone defects. This biomaterial coating strategy represents a cost-effective and facile approach, translatable into a robust clinical therapy for musculoskeletal applications
