Approximately 100,000 ACL reconstructions are performed each year. After surgery, patients who return to sport often wear a hard brace or neoprene sleeve to protect the knee. This study refutes common belief that a hard knee brace is more protective than a neoprene sleeve.
A US Food and Drug Administration (FDA) review has found only limited evidence for an association between eating tomatoes and a decreased risk of certain cancers. Review found no evidence that tomatoes reduced the risk of lung, colorectal, breast, cervical, or endometrial cancer.
Chronic infection with the hepatitis C virus (HCV) is the leading reason patients receive liver transplants today. Unfortunately, infection of the new liver by residual HCV in the blood is inevitable, and the immune system suppression crucial to prevent transplant rejection can worsen HCV-mediated disease in transplant patients.
Scientists at the University of Bonn, together with colleagues from Romania, have discovered a gene variant that significantly increases the risk of developing gallstones (Hepatology No. 46, July 11, 2007, DOI 10.1002/hep.21847). It is estimated that one in ten Europeans has this variant in their hereditary disposition. For those affected, the likelihood of developing a gallstone in the course of their life is two to three times higher.
A startling discovery on the development of human embryonic stem cells by scientists at McMaster University will change how future research in the area is done.
Prostate cancer is the most common cancer in American men, with an estimated incidence of 234,460 cases and 27,360 deaths in 2006. Screening for prostate cancer remains controversial due to insufficient evidence to recommend for or against screening.
Those with heavy hearts ? in the literal not figurative sense ? long have been known to be prone to cardiac arrest and sudden death. But many are not, and who among them is subject to serious risk is a mystery.
New evidence published on bmj.com confirms that hormone replacement therapy (HRT) should not be prescribed to older women who are many years past menopause to help prevent chronic conditions such as heart disease.
Chronic mild stress in pregnant mothers may increase the risk that their offspring will develop cerebral palsy — a group of neurological disorders marked by physical disability — according to new research in mice. The results may be the first to demonstrate such effects of stress on animals in the womb.
Kaposi sarcoma is unique among cancers because most tumors grow from a small number of different cells, whereas nearly all other cancers arise from a single cell, according to a study published online July 10 in the Journal of the National Cancer Institute.
