Anyone traveling soon might want to brush up a bit on the problem of deep vein thrombosis, venous thromboembolism (VTE), since the WHO just issued warnings again in its Research Into Global Hazards of Travel project.

Referring back to the first of today's posts, the WHO says, "Travellers can take "common-sense" measures to reduce the risks of contracting VTE by regularly exercising their calf and ankle muscles during a journey, or simply getting up and moving around a bit."

if you're flying with kids, chasing them around a plane should keep you healthy.

And here's a study that suggests that estrogen therapy might protect the aging brain cells of post-menopausal women.

As if there wasn't enough fodder in the HRT debate, this research out of the Mount Sinai School of Medicine in New York finds more potential benefits. Although millions of women gave up their hormones when a 2002 study linked them to a rise in breast cancer risks, there may be more to the equation than previously understood.

And while we're on estrogen ... you know what I mean ... another study is showing that it may reduce heart disease.

Apparently, this one found lower levels of coronary artery calcification in women on HTR.

Published in the June 21 issue of the New England Journal of Medicine, this study was a follow-up on the Women's Health Initiative, the largest study done of postmenopausal women.

Just in case you don't have enough to worry about, here's some research that suggests that women with few older female relatives may carry a genetic risk of breast cancer.

This is a complicated one, so worth a read if there's interest ... and it is interesting ... saying that genetic risk models for breast cancer underestimated a deadly gene mutation in women with fewer than two female relatives who lived to be older than age 45 on both sides of the family.

And just so the dads out there don't think I'm ignoring their health ... Could I do something like that? ... here's a study on prostate cancer published by the Journal of Clinical Investigation that found that omega-3 fatty acids found in food might improve the prognosis for men with a genetic predisposition.

"This study clearly shows that diet can tip the balance toward a good or bad outcome," said Yong Q. Chen, senior researcher at Wake Forest University School of Medicine in Winston-Salem, North Carolina.

"It's possible that a change in diet could mean the difference between dying from the disease and surviving with it."

Foods high in Omega-3 fatty acids include fish like salmon, halibut, tuna, sardines and mackerel, and fish oil such as cod liver oil, English walnuts and flaxseeds.

With prostate cancer among the leading causes of cancer death in American men, tuna and walnut sandwiches ... or a daily supplement ... could be a common sense addition.
