Avoiding a Late Supper Associated with Reduced Prostate Cancer Risk

Eating supper before 9 p.m. or waiting a minimum of two hours after eating before going to bed is linked to a 20 percent reduction in prostate cancer risk, according to research in the International Journal of Cancer.

Scientists at the Barcelona Institute for Global Health (ISGlobal) reviewed questionnaires completed by 621 men with prostate cancer and 872 men in a control group. Participants detailed their sleep patterns, timing of meals, whether they prefer morning or evening activity, and compliance with cancer-prevention guidelines.

“Further research ... is needed in order to understand the reasons behind these findings, but everything seems to indicate that the timing of sleep affects our capacity to metabolize food,” ISGlobal researcher Dora Romaguera, one of the study’s authors, stated in a news release.

Scientists found a similar reduction in breast cancer risk when they compared responses of 1,205 people who have breast cancer with responses from 1,321 controls.

Earlier research has found an association between long-term night shift work and aggressive prostate cancer.


Bariatric Surgery Linked to Fast Improvement in Hypogonadism

Speedy reversal of obesity-related hypogonadism is among the benefits of a particular type of bariatric surgery, according to researchers at the University of Padova in Italy.

Bariatric surgery is associated with improvements in conditions such as diabetes and high blood pressure.

Research presented at the European Congress on Obesity in Vienna assessed how quickly sleeve gastrectomy affects hypogonadism among morbidly obese men. It found that one month after a group of 29 morbidly obese men underwent the procedure, the proportion with hypogonadism had dropped from 51.6 percent to 11.6 percent. Levels of testosterone rose, on average, by 85 percent — a higher level than that found in a control group of 19 healthy men of normal weight.

Previous research had assessed only whether weight loss affects hypogonadism in the long term.


Testosterone Replacement Therapy May Aid Men with COPD

Use of steroid-based medications to treat chronic obstructive pulmonary disease (COPD) can heighten the risk of low testosterone, which can exacerbate COPD. However, research published in Chronic Respiratory Disease finds progression of COPD may be slowed with testosterone replacement therapy.

The study, by scientists at The University of Texas Medical Branch (UTMB) at Galveston, builds on research suggesting a link between the therapy and improved lung function among men with COPD. It examined data on about 700 men ages 40 to 63 or 66 and older with COPD who had undergone testosterone replacement therapy.

“Middle-aged testosterone replacement therapy users had a 4.2 percent greater decrease in respiratory hospitalizations compared with nonusers, and older testosterone replacement therapy users had a 9.1 percent greater decrease,” Jacques Baillargeon, UTMB Professor in Preventive Medicine and Community Health, stated in a news release.
