Statins did not reduce colorectal cancer in WHI analysis

PHILADELPHIA — The use of statins among a group of postmenopausal women did not reduce the risk for colorectal cancer, according to the results of a prospective analysis of data from the large population-based Women's Health Initiative (WHI).

"The results of our study are consistent with the majority of the literature suggesting no significant reduction in colorectal cancer risk among users of statins," said Michael S. Simon, M.D., professor of oncology in the department of oncology at Wayne State University and Barbara Ann Karmanos Cancer Institute, Detroit.

Fat sand rats are SAD like us

Fat sand rats are SAD like us

Saying goodbye to summer can be difficult for everybody. In some people the onset of winter triggers Seasonal Affective Disorder, or SAD, a mood disorder in which sufferers experience symptoms of depression. Happily, a special kind of gerbil exhibits remarkably similar reactions to SAD treatments as humans, opening a promising new channel for study and treatment of the common complaint.

Soy may stop prostate cancer spread

CHICAGO --- Northwestern Medicine researchers at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University have found that a new, nontoxic drug made from a chemical in soy could prevent the movement of cancer cells from the prostate to the rest of the body.

These findings will be presented at the Ninth Annual American Association for Cancer Research Frontiers in Cancer Prevention Research Conference.

Dangerous PFCA chemicals in food wrappers likely migrating to humans

University of Toronto scientists have found that chemicals used to line junk food wrappers and microwave popcorn bags are migrating into food and being ingested by people where they are contributing to chemical contamination observed in blood.

Perfluorinated carboxylic acids or PFCAs are the breakdown products of chemicals used to make non-stick and water- and stain-repellant products ranging from kitchen pans to clothing to food packaging. PFCAs, the best known of which is perfluorooctanoic acid (PFOA), are found in humans all around the world.

Special skin keeps fish species alive on land

A new study shows how an amphibious fish stays alive for up to two months on land. It's all in the skin.

Discovery of an anti-inflammatory substance

The messenger interleukin-27 plays an important role when the human body blocks inflammations. This was discovered by an international research team, of which the Kiel Professors Joachim Grötzinger and Stefan Rose-John, as well as the doctoral candidate, Björn Spudy, are a part of. The research findings of the scientists from Kiel, the US and Great Britain were published yesterday, Sunday (7 November 2010), in the online advance edition of Nature Immunology.

Study examines risk of heterosexual HIV transmission in China

A new study by researchers at the Johns Hopkins Bloomberg School of Public Health examines the burden of HIV and sexually transmitted disease among male clients of the commercial sex industry in China's Sichuan province. Since 2007, heterosexual transmission has replaced injecting drug use as the primary transmission mode of all HIV infections in China. The study is available online in advance of publication in the journal Sexually Transmitted Infections.

Scientist chronicle nanoparticles' journey from the lungs into the body

BOSTON – Using a novel, real-time imaging system, scientists have tracked a group of near-infrared fluorescent nanoparticles from the airspaces of the lungs, into the body and out again, providing a description of the characteristics and behavior of these minute particles which could be used in developing therapeutic agents to treat pulmonary disease, as well as offering a greater understanding of the health effects of air pollution.

Study sheds light on aromatase inhibitor joint pain syndrome

Breast cancer patients are more likely to have joint pain from taking aromatase inhibitors (AIs) if they have advanced stage cancer, according to a study presented at the American College of Rheumatology's annual meeting, held Nov. 7-11, in Atlanta. The study is one of the first to identify factors that increase the likelihood that a patient will suffer joint pain from AI therapy.

Fearless children show less empathy, more aggression

"The results of this study show that fearless behavior in children can be identified and is related to neurological and genetic predisposition. This type of behavior has less correlation – at least in infancy – with standards of educational processes or parenting practice," says Dr. Inbal Kivenson-Baron, who carried out the study.

Fat cells reach their limit and trigger changes linked to type 2 diabetes

Scientists have found that the fat cells and tissues of morbidly obese people and animals can reach a limit in their ability to store fat appropriately. Beyond this limit several biological processes conspire to prevent further expansion of fat tissue and in the process may trigger other health problems.

Privacy safeguards in Canadian military insufficient: Updated rules needed

Privacy legislation and protocols to safeguard the health information of members of the military are lacking, and the head of Canada's military must take action to ensure health privacy for all staff, states an editorial in the Canadian Medical Association Journal (CAMJ) http://www.cmaj.ca/cgi/doi/10.1503/cmaj.101630.

Recent violations at Veterans Affairs Canada of privacy regarding sensitive health information raise questions about the military's ability to protect personal health information.
