Abstract Depression is a polygenic trait that causes extensive periods of disability. Previous genetic studies have identified common risk variants which progressively increased in number with increasing sample sizes the respective studies. Here, we conduct genome-wide association study 322,580 UK Biobank participants for three depression-related phenotypes: broad depression, probable major depressive disorder (MDD), and International Classification Diseases (ICD, version 9 or 10)-coded MDD....

Chronic pain is highly prevalent worldwide and represents a significant socioeconomic public health burden. Several aspects of chronic pain, for example back severity-related phenotype 'chronic grade', have been shown previously to be complex heritable traits with polygenic component. Additional pain-related phenotypes capturing an individual's overall sensitivity experiencing reporting also suggested as focus investigation. We made use measure the number sites in individuals within UK...
Higher body mass index (BMI) is a risk factor for cardiometabolic disease; however, the underlying causal associations remain unclear.To use UK Biobank data to report estimates of association between BMI and disease outcomes traits, such as pulse rate, using mendelian randomization.Cross-sectional baseline from population-based cohort study including 119 859 participants with complete phenotypic (medical sociodemographic) genetic data. Participants attended 1 22 assessment centers across...

The behaviour of nuclear bag and chain intrafusal fibres in isolated cat muscle spindles with a blood supply, during stimulation dynamic gamma axons, beta or static axons ventral root filaments was observed recorded on still moving film. 2. Most were controlled by one axon (sometimes axon) three which often non-selective distribution. A large majority fusimotor pole the spindle only. 3. Dynamic produced focal contraction only two any this fibre never activated axons. Maximal tetanic...
The association between loneliness and suicide is poorly understood. We investigated how living alone, emotional support were related to self-harm in a longitudinal design.Between 2006 2010 UK Biobank recruited assessed detail over 0.5 million people middle age. Data linked prospective hospital admission mortality records. Adjusted Cox regression models used investigate relationships arrangements, support, both as outcomes.For men, alone (Hazard Ratio (HR) 2.16, 95%CI 1.51-3.09) with...
Reported associations between shiftwork and health have largely been based on occupation-specific, or single sex studies that might not be generalizable to the entire working population. The objective of this study was investigate whether independently associated with obesity, diabetes, poor sleep, well-being in a large, UK general population cohort.Participants Biobank who were employed at time assessment included. Exposure variables self-reported (any night shiftwork); outcomes objectively...
Apolipoprotein (APOE) e4 genotype is an accepted risk factor for accelerated cognitive aging and dementia, though its neurostructural substrates are unclear. The deleterious effects of this on brain structure may increase in magnitude into older age. This study aimed to investigate UK Biobank the association between APOE allele presence vs. absence imaging variables that have been associated with worse abilities; whether varies by cross-sectional We used magnetic resonance (MRI) genetic data...
UK Biobank is a prospective cohort study of around half-a-million general population participants, recruited between 2006 and 2010, with baseline studies at recruitment multiple assessments since. From 2014 to date, magnetic resonance imaging (MRI) has been pursued in participant sub-sample, the aim scan n = 100k. This sub-sample studied widely therefore understanding its relative characteristics important for future reports. We aimed quantify psychological physical health compared rest...
Abstract Mood instability is a core clinical feature of affective and psychotic disorders. In keeping with the Research Domain Criteria approach, it may be useful construct for identifying biology that cuts across psychiatric categories. We aimed to investigate biological validity simple measure mood evaluate its genetic relationship several disorders, including major depressive disorder (MDD), bipolar (BD), schizophrenia, attention deficit hyperactivity (ADHD), anxiety post-traumatic stress...
Anhedonia is a core symptom of several psychiatric disorders but its biological underpinnings are poorly understood. We performed genome-wide association study state anhedonia in 375,275 UK Biobank participants and assessed for genetic correlation between neuropsychiatric conditions (major depressive disorder, schizophrenia, bipolar obsessive compulsive disorder Parkinson's Disease). then used polygenic risk score approach to test loading both brain structure function. This included:...
Objectives To assess whether a history of major depressive disorder (MDD) in middle-aged individuals with hypertension influences first-onset cardiovascular disease outcomes. Design Prospective cohort survival analysis using Cox proportional hazards regression median follow-up 63 months (702 902 person-years). Four mutually exclusive groups were compared: only (n=56 035), MDD (n=15 098), comorbid plus (n=12 929) and an unaffected (no hypertension, no MDD) comparison group (n=50 798). Setting...
Risk-taking behaviour is a key component of several psychiatric disorders and could influence lifestyle choices such as smoking, alcohol use, diet. As phenotype, risk-taking therefore fits within Research Domain Criteria (RDoC) approach, whereby identifying genetic determinants this trait has the potential to improve our understanding across different disorders. Here we report genome-wide association study in 116,255 UK Biobank participants who responded yes/no question "Would you consider...
Abstract Major depression is a debilitating psychiatric illness that typically associated with low mood, anhedonia and range of comorbidities. Depression has heritable component remained difficult to elucidate current sample sizes due the polygenic nature disorder. To maximise size, we meta-analysed data on 807,553 individuals (246,363 cases 561,190 controls) from three largest genome-wide association studies depression. We identified 102 independent variants, 269 genes, 15 gene-sets...
