What is DHEA? DHEA is a critical component to jumpstarting an individual’s hormonal balance. DHEA, short for Dehydroepiandrosterone is a...
Eating lots of protein may help lower the risk of stroke, according to a new study. New research reveals that people who eat more protein, especially in the form of fish, are less likely to suffer stroke than those with diets lower in protein.
"The amount of protein that led to the reduced risk was moderate-equal to 20 grams per day," lead researcher Xinfeng Liu, MD, PhD, of Nanjing University School of Medicine in Nanjing, China, said in a news release. "Additional, larger studies are needed before definitive recommendations can be made, but the evidence is compelling."The latest meta-analysis involved seven studies with a total of 254,489 participants who were followed for an average of 14 years.
Researchers from Monash University in Australia say that giving testosterone treatments to postmenopausal women can improve their verbal learning and memory. While menopause is linked with memory decline due to decreased production of the female sex hormone estrogen, this study found that giving older women treatments of the male sex hormone can help protect them against cognitive decline that often accompanies menopause. Testosterone can also help give women a boost in sexual desire, bone density and energy while improving mood.
A new study found that men who were prescribed medications for erectile dysfunction or low testosterone levels were more likely to be taking opioid (narcotic) medications for chronic back pain.
"People who have persistent pain problems need to know that a potential side effect of long-term opioid use may be erectile dysfunction," said lead study author Dr. Richard Deyo, a clinical investigator for the Kaiser Permanente Center for Health Research in Portland, Ore. "This is not a well-known potential side effect among patients, and it should be considered when thinking about treatment." Deyo also noted, however, that "the nature of this study as an observational study limits our ability to make a causal [cause-and-effect] inference. Opioid use and erectile dysfunction seem to go together, but we have to be cautious about saying one causes the other."
he four trials, while small, showed a moderate improvement in patients with chronic stable heart failure, with some subjects experiencing a 50 percent enhancement in their capacity to walk, which is linked to the testosterone’s ability to help improve exercise endurance and the shortness of breath associated with heart failure patients.
The lead study author, Dr. Justin Z. Ezekowitz, cautioned that because of the small number of subjects – just 198 across the four trials – there was much more work to be done to determine the efficacy of testosterone across a broad spectrum of patients. Ezekowitz, who is the Heart Function Clinic director at the University of Alberta in Edmonton, further clarified that just because of the positive outlook from this study "We don't want patients and their loved ones rushing to physicians to misinterpret the findings."
"Declining testosterone levels are not an inevitable part of the aging process, as many people think," said study co-author Gary Wittert, MD, professor of medicine at the University of Adelaide in Adelaide, Australia. "Testosterone changes are largely explained by smoking behavior and changes in health status, particularly obesity and depression."
"The substantial weight loss found in our study—an average of 36 pounds—was a surprise," said the study's lead author, Farid Saad, PhD, of Berlin-headquartered Bayer Pharma.
Although prior studies using testosterone therapy in testosterone-deficient men consistently show changes in body composition, such as increased lean mass and decreased fat mass, Saad said the net effect on weight seemed unchanged in those studies. However, Saad said their study, which took place in Germany, had a longer follow-up by at least two years and used long-acting injections of testosterone.
Hormone affects fat accumulation in lower body by changing cell function, Concordia Study Proves
Not all fat is created equal. Compared to people who accumulate fat in the hips and thighs, people who store fat in their stomachs run a much higher risk of cardiovascular disease, diabetes and other obesity-associated health issues.
A study found that elderly men who had low levels of natural steroid hormones were at a higher chance for developing cardiovascular disease. The researchers presented their findings this Saturday at The Endocrine Society's 94th Annual Meeting, which is being held in Houston, Texas.
Dehydroephiandrosterone (DHEA) is the steroid that was studied. The hormone is secreted by the adrenal gland. DHEA-S, the sulfated form, floats through the blood and is converted in other tissues and is turned into estrogen and testosterone hormones.
The risk of developing thyroid cancer increases with the number of dental x-rays that are taken, according to new research.
About 1,900 new cases of thyroid cancer are diagnosed each year in the UK and the incidence rates have more than doubled from 1.4 to 2.9 per 100,000 people between 1975 and 2006.
