Testosterone levels are reduced in obesity, the metabolic syndrome and type 2 diabetes. Low testosterone levels are now being recognised as an independent risk factors for these conditions. Findings from men undergoing androgen suppression as treatment for prostate cancer confirm that the hypogonadal state increases body fat mass and serum insulin and there is a high rate of developing new diabetes in this population. Clinical trial data are consistent in showing reductions in body fat mass during testosterone replacement therapy. There are also trials showing improvements in insulin resistance and glycaemic control with testosterone. Most of the trials in this area to date have been of small size and the promising results require confirmation in larger trials, which are underway. In the longer term, large trials should be conducted to assess the potentially beneficial effects of testosterone on cardiovascular risk in this and other patient groups. In the meantime physicians involved in the care of men with diabetes should remain vigilant for the symptoms and signs of hypogonadism. Testosterone replacement therapy should be considered for those men with subsequently confirmed hypogonadism.
Candida (Torulopsis) glabrata is a fungus with a diversity of habitats and an enlarging clinical spectrum. It is found as normal human flora in the gastrointestinal tract, skin, and vagina and also found in nature in soil and in animals. It was initially thought to represent a nonpathogenic saprophyte, however, it has been recovered with increasing frequency from clinical specimens. It is now recognized as a cause of disease in the normal and compromised host.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
