Background In patients with atrial fibrillation (AF), the impact of peripheral artery disease (PAD) on oral anticoagulant (OAC) therapy use and the risk of outcomes remains unclear. Objective To analyse the epidemiology of PAD in a large cohort of European and Asian AF patients, and the impact on treatment patterns and risks of adverse outcomes. Methods We analysed AF patients from two large prospective observational registries. OAC prescription and risk of outcomes were analysed according to the presence of PAD, using adjusted Logistic and Cox regression analyses. The primary outcome was the composite of all-cause death and major adverse cardiovascular events (MACE). Interaction analyses were also performed. Results Fifteen-thousand-four-hundred-ninety-seven patients with AF (mean age 68.9, SD 11.6 years; 38.6% female, 30% from Asia) were included in the analysis. PAD was found in 941 patients (6.1%), with a higher prevalence among European individuals compared to Asian (8.1% vs 1.2%,

Background Obesity particularly during childhood is considered a global public health crisis and has been linked with later life health consequences including mental health. However, there is lack of causal understanding if childhood body size has a direct effect on mental health or has an indirect effect after accounting for adulthood body size. Methods Two-sample Mendelian randomization (MR) was performed to estimate the total effect and direct effect (accounting for adulthood body size) of childhood body size on anxiety and depression. We used summary statistics from a genome-wide association study (GWAS) of UK Biobank (n = 453,169) and large-scale consortia of anxiety (Million Veteran Program) and depression (Psychiatric Genomics Consortium) (n = 175,163 and n = 173,005, respectively). Results Univariable MR did not indicate genetically predicted effects of childhood body size with later life anxiety (beta = − 0.05, 95% CI = − 0.13, 0.02) and depression (OR = 1.06, 95% CI = 0.94, 1

Background Gabapentinoids are increasingly prescribed in inflammatory arthritis (IA), despite no trial evidence for efficacy at managing pain in this population. Observational studies in non-IA populations suggest gabapentinoids are associated with fractures but are limited by methodological heterogeneity/potential residual confounding. Patients with IA generally have an increased risk of fracture so may be particularly vulnerable. We examined the relationship between fractures and gabapentinoids in patients with IA who had all been prescribed a gabapentinoid at some point (to minimise confounding by indication). Methods Our matched case–control study used linked national data from English primary care (Clinical Practice Research Datalink Aurum) and Hospital Episode Statistics. A cohort was constructed of adults with IA, contributing data 01/01/2004–31/03/2021, and ever prescribed oral gabapentinoids. Cases with an incident fracture post-cohort inclusion were ascertained and 1:5 risk s

Background Endometriosis, affecting 10% of women in their reproductive years, remains poorly understood. Both individual and environmental unexplained factors are implicated in this heterogenous condition. This study aims to examine the influence of a Western diet on endometriosis lesion development in mice and to uncover the mechanisms involved. Methods Mice were fed either a control diet or a Western diet (high in fatty acids and low in fiber) for 4 weeks. Endometriosis was then surgically induced, and lesion development was monitored by ultrasound. After 7 weeks, the mice were sacrificed for analysis of lesion characteristics through RT-qPCR, immunohistochemistry, and flow cytometry. Additionally, the intestinal microbiota was assessed using 16S rRNA gene sequencing. Results Mice on the Western diet developed lesions that were significantly twice as large compared to those on the control diet. These lesions exhibited greater fibrosis and proliferation, alongside enhanced macrophage

Background Non-alcoholic fatty liver disease (NAFLD) is associated with an increased incidence of hepatic and extrahepatic cancers, in particular those linked to obesity. In people with chronic liver disease, aspirin may confer protection against hepatocellular carcinoma (HCC). We explore the potential chemoprotective effect of aspirin/other anti-platelet agents on obesity-related cancers, including HCC in people with NAFLD. Methods We performed a retrospective cohort study of anonymised electronic medical records using the TriNetX network (Cambridge, MA, USA), a global federated database. We identified adults aged 18 or over with a diagnosis of NAFLD, prior to commencing antiplatelet agents. Two groups were created: antiplatelet (1) versus no antiplatelet use (2). We propensity score matched for nine variables. Antiplatelet use was defined as aspirin, ticagrelor, cangrelor, clopidogrel or prasugrel use for at least 1 year. The outcomes of interest were incidence of HCC and other obesi
