OBJECTIVE Immobilization and subsequent weakness are consequences of critical illness. Despite the theoretical advantages of physical therapy to address this problem, it has not been shown that physical therapy initiated in the intensive care unit offers benefit. DESIGN AND SETTING Prospective cohort study in a university medical intensive care unit that(More)
The objective of the present study was to estimate the prevalence of the different pathological conditions causing clinically evident androgen excess and to document the degree of long-term success of suppressive and/or antiandrogen hormonal therapy in a large consecutive population of patients. All patients presenting for evaluation of symptoms potentially(More)
BACKGROUND Vitamin D deficiency is common following bariatric surgery and is due to a combination of baseline deficiency and postoperative malabsorption. There are few prospective studies evaluating the appropriate dose of vitamin D to prevent and treat vitamin D deficiency following bariatric surgery. METHODS We evaluated three doses of vitamin D3 (800,(More)
Atherosclerosis is a complex process with multiple mechanisms and factors contributing to its initiation and progression. Detection and quantification of coronary artery calcium (CAC) scores with electron beam tomography has been shown to correlate with obstructive and nonobstructive coronary artery disease (CAD). Pathogen-triggered calcification could play(More)
OBJECTIVES To determine the prevalence of polycystic ovaries (PCO) in Asian women living in England who are of Indian subcontinent origin or ancestry and to investigate the relationship between the presence of PCO and/or non-insulin dependent diabetes mellitus (NIDDM) and insulin sensitivity and other metabolic parameters. DESIGN A random sample of Indian(More)
BACKGROUND Vitamin D deficiency is common in patients after bariatric surgery. However, obesity itself has also been associated with decreased vitamin D. The prevalence of vitamin D deficiency in obese persons has not previously been compared to non-obese controls when controlling for factors that could affect vitamin D status. METHODS We evaluated 25(More)
BACKGROUND Recent studies have identified unique small ribonucleic acids called microRNAs (miRNAs) in colonic tumour tissue and blood that may accurately diagnose the presence of colorectal cancer and help predict disease recurrence. This review explores the potential role of these biomarkers. METHODS A literature search identified studies describing(More)
Thiazolidinediones (TZDs) are a new class of compounds that improve insulin sensitivity in type 2 diabetic patients as well as in rodent models of this disease. These compounds act as ligands for a member of the nuclear hormone receptor superfamily, peroxisome proliferator-activated receptor-gamma (PPAR-gamma), which is highly expressed in adipose tissue(More)
Increased dietary consumption of docosahexaenoic acid (DHA) is associated with decreased risk for Alzheimer's disease (AD). These effects have been postulated to arise from DHA's pleiotropic effects on AD pathophysiology, including its effects on β-amyloid (Aβ) production, aggregation, and toxicity. While in vitro studies suggest that DHA may inhibit and(More)
