Quantitative ultrasound of the heel captures heel bone properties that independently predict fracture risk and, with bone mineral density (BMD) assessed by X-ray (DXA), may be convenient alternatives for evaluating osteoporosis and fracture risk. We performed a meta-analysis of genome-wide association (GWA) studies to assess the genetic determinants of heel(More)
OBJECTIVES Suicide among older adults is a major public health issue worldwide. Although studies have identified psychological, physical, and social contributors to suicidal thoughts in older adults, few have explored the specific interactions between these factors. This article used a novel statistical approach to explore predictors of suicidal ideation in(More)
BACKGROUND Chronic exposure to high level of inorganic arsenic in drinking water has been associated with Type 2 Diabetes (T2D). Most research has been ecological in nature and has focused on high levels of arsenic exposure with few studies directly measuring arsenic levels in drinking water as an index of arsenic exposure. The effect of low to moderate(More)
The aim of this research is to estimate the prevalence of excessive daytime sleepiness in an older population and associations with sociodemographic, health, and lifestyle factors using a cross-sectional, population-based study. Participants were men (1560) and women (1759), aged 55 to 85 years, enrolled in the Hunter Community Study, a longitudinal study(More)
BACKGROUND This study measured serum concentrations of vascular risk factors, asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) in a representative sample of older community-dwelling adults and determined their associations with objective and subjective memory impairment. METHODS Data on clinical, lifestyle, and demographic(More)
Genome-wide association studies (GWAS) have not consistently detected replicable genetic risk factors for ischemic stroke, potentially due to etiological heterogeneity of this trait. We performed GWAS of ischemic stroke and a major ischemic stroke subtype (large artery atherosclerosis, LAA) using 1,162 ischemic stroke cases (including 421 LAA cases) and(More)
AIMS An increasing dialysis population and insufficient supply of transplant organs necessitate that patients are carefully evaluated prior to registration on the national waiting list to ensure effective utilization of a scarce resource. We have assessed listing practice in two renal units within the North of England Transplant Alliance. METHODS(More)
RATIONALE Methylarginines are endogenous nitric oxide synthase inhibitors that have been implicated in animal models of lung disease but have not previously been examined for their association with spirometric measures of lung function in humans. OBJECTIVES This study measured serum concentrations of asymmetric and symmetric dimethylarginine in a(More)
AIMS There are a number of studies showing that zinc supplementation may improve glucose handling in people with established diabetes. We sought to investigate whether this zinc-dependent improvement in glucose handling could potentially be harnessed to prevent the progression of pre-diabetes to diabetes. In this double-blind randomized placebo-controlled(More)
