the risks associated with exclusive pipe smoking, Jane Henley of the American Cancer Society in Atlanta, and colleagues analyzed data from 138,307 men (15,263 current or former pipe users, and 123,044 men who had never used tobacco products) enrolled...

Benefits of screening for lung cancer with CT are not proven
...tients per thousand would die of lung cancer. This estimate
is close to the established lung cancer mortality rate of 3.9 to 4.4 deaths per thousand found in studies that don't use CT to screen patients. Their findings call into question the growing practice of charging smokers for expensive CT scans to detec...
When it comes to cancer prognosis, it's not just the tumor that matters

survival so patients receive more accurate information on their chances for survival. Second, it will improve the validity of cancer research. For example, it may not be appropriate to include all cancer patients in a given drug trial, because comor...

Matching method helps doctors successfully transplant higher-risk kidneys
... effectively. Wake Forest Baptist's approach is to estimate
the function of a donated kidney and to match it with the needs of a potential recipient. "In the past, kidneys were matched exclusively by blood and tissue type," said Stratta. "Now, we are matching based on age, weight and kidney function. Someone ...

the relative risk of breast cancer in relation to general and abdominal obesity and evaluate whether HRT plays a role in this relationship, a study was conducted by Petra H. Lahmann, Ph.D. of the German Institute of Human Nutrition in Potsdam-Rehbrck...
Hospital gowns' benefits outweigh costs in intensive care unit

potential financial costs of not requiring gowns, the researchers used a new approach called colonization pressure to assess risk of infections spreading among patients. Colonization pressure on a patient is determined by calculating the percentage o...
