Exercise may cut endometrial cancer risk for heavy women

Overweight and obese women who get plenty of exercise may have a lower risk of endometrial cancer than if they were sedentary, according to new research.

 

Strenuous and moderate physical activity were linked to lowered risk for heavy women, but there was no association between activity level and endometrial cancer risk for thinner women, Christina M. Dieli-Conwright of the Beckman Research Institute of City of Hope in Duarte, California, and her colleagues found.

Aspirin tied to smaller lung and colon cancer tumors

Colon and lung cancer patients who regularly took low-dose aspirin before their diagnosis tended to have less advanced tumors, in a new study.

 

Scientists already knew that aspirin was tied to a decreased risk of death for people with colon cancer, said senior author Yudi Pawitan.

 

"We showed evidence that it is also beneficial for lung cancer, and has both early and late protective effects," Pawitan, of the department of medical epidemiology and biostatistics at the Karolinska Institutet in Stockholm, Sweden, told Reuters Health.

Blood clots could be sucked out of the brain by a robotic device

Blood clots could be sucked out of the brain by a robotic device | Longevity science | Scoop.it

Intracerebral hemorrhaging is what occurs when a blood vessel in the brain bursts, and the blood which subsequently leaks out of that vessel forms a clot that places pressure on the surrounding brain tissue. It’s not that uncommon of an occurrence, it’s difficult to treat, and is fatal in about 40 percent of cases. Help may be on the way, however. A team from Nashville’s Vanderbilt University has created a robotic device that is designed to remove those clots, in a safe and minimally-invasive fashion.

 

As things currently stand, surgery is a risky approach to removing the clots. An access hole has to be drilled in the skull, and unless the clot is right on the outside of the brain, healthy brain tissue must be disturbed and damaged in order to reach it. The amount of damage caused by the surgery may even outweigh the benefits of removing the clot, which is why physicians often instead choose to administer anti-inflammatory drugs and hope for the best.

High blood sugar tied to dementia in non-diabetics

Elderly people with high blood sugar - but not high enough to be diabetic - face a slightly greater risk of developing dementia, according to a new study of over 2,000 volunteers.

 

The research, published in the New England Journal of Medicine, does not prove that high glucose levels directly cause dementia.

Soda drinking tied to kids' behavior problems: study

Soda drinking tied to kids' behavior problems: study | Longevity science | Scoop.it

Children who drink soda tend to score slightly higher on scales that measure aggressive behavior than kids who don't drink the carbonated beverages, according to a new study.

 

The study's lead author cautioned, however, that the increase may not be noticeable for individual children and the researchers can't prove soda caused the bad behaviors.

Ultrasound-emitting "band-aids" speed healing of venous ulcers

Ultrasound-emitting "band-aids" speed healing of venous ulcers | Longevity science | Scoop.it

Venous ulcers are nasty things, often found on the lower extremities of elderly or inactive people. They occur when high blood pressure causes the skin adjacent to the affected veins to break down, leaving open wounds that take months or even years to heal. Standard treatments include compression bandages, infection control and standard wound dressings, although these approaches don’t work in all cases. Now, however, scientists are getting good results using band-aid-like patches that emit ultrasound into the ulcers.

 

It’s been suspected for some time that ultrasound could have a curative effect on the ulcers, although most studies have investigated the use of fairly high frequencies – around 1 to 3 megahertz. Instead, a group of scientists from Philadelphia’s Drexel University tried using frequencies that were considerably lower.
