Baldness as a Signal of Heart Disease Risk

Baldness as a Signal of Heart Disease Risk

Baldness may indicate an increased risk for coronary heart disease.
The risk is associated only with male pattern baldness, the kind that starts at the top or back of the head, and not with a receding hairline, according to researchers who reviewed six studies that included 37,000 participants.
The analysis, published online in BMJ Open, found that baldness increased the risk for heart disease by between 30 and 40 percent compared with men with a full head of hair. They found the association among men 55 to 60 as well as among older men, and the more severe the baldness, the greater the risk.
The reason for the association is unclear, but the authors suggest that known risk factors for heart disease — hypertension, high cholesterol, smoking and others — may affect both conditions, and that baldness may be a marker of atherosclerosis. In previous studies, baldness has been linked to an increased risk of prostate cancer, diabetes and high blood pressure.
“It may be premature to confirm this relationship on the basis of only six studies,” said a co-author, Dr. Kazuo Hara, an associate professor of medicine at the University of Tokyo. “But the ultimate aim is to be able to predict the risk for heart disease more precisely in clinical practice.”

Artificial pancreas ... an option

Coming Soon: 'Artificial Pancreas' Options for Diabetes Miriam E Tucker June 20, 2016   NEW ORLEANS — Nearly closed-loop systems (also referred to as an "artificial pancreas") for improving glycemic control and minimizing hypoglycemia in type 1 diabetes are advancing rapidly, including iterations that deliver insulin alone, insulin with glucagon, or glucagon alone. Findings for several of the products in development demonstrating improvements in glycemic control and reductions in hypoglycemia were presented here at the  American Diabetes Association (ADA) 2016 Scientific Sessions . "Some people may do well on insulin only, while others may need glucagon," Vincent Crabtree, PhD, director of the artificial pancreas program at JDRF, in New York, told  Medscape Medical News , adding, "JDRF would like people to have choice, and we'd like all to be covered [by payers]." The insulin-only hybrid closed-loop 670G system (Medtronic MiniMed) is the...
Liver Stem Cells Discovered in Mice Share on email Share on facebook Share on twitter Scientists successfully identified and grew a renewable population of liver stem cells for the first time, a new study reported. Tissues derived from these stem cells slightly boosted liver function when implanted into mice with a liver disorder. The findings could eventually lead to approaches that help rejuvenate damaged livers in people. A single cell was coaxed to mature into liver cells that produce common liver proteins (green and red).  Image courtesy of Huch et al.,  Nature . The liver is a large, versatile organ that has many jobs, including cleansing blood and digesting food. The liver also has a unique ability to quickly regenerate and regain its original size if partially removed by surgery. Scientists have long known that stem cells that have the potential to create more liver cells must exist in the adult liver. But until now, no one had found a way to detect a...

Erythropoietin as a Retinal Angiogenic Factor in Proliferative Diabetic Retinopathy

Although vascular endothelial growth factor (VEGF) is a primary mediator of retinal angiogenesis, VEGF inhibition alone is insufficient to prevent retinal neovascularization. Hence, it is postulated that there are other potent ischemia-induced angiogenic factors. Erythropoietin possesses angiogenic activity, but its potential role in ocular angiogenesis is not established. METHODS We measured both erythropoietin and VEGF levels in the vitreous fluid of 144 patients with the use of radioimmunoassay and enzyme-linked immunosorbent assay. Vitreous proliferative potential was measured according to the growth of retinal endothelial cells in vitro and with soluble erythropoietin receptor. In addition, a murine model of ischemia-induced retinal neovascularization was used to evaluate erythropoietin expression and regulation in vivo. RESULTS The median vitreous erythropoietin level in 73 patients with proliferative diabetic retinopathy was significantly higher than that in 71 patients with...
