Researchers at the University Of Southern California, School Of Dentistry release results of clinical data that links oral bisphosphonates to increased jaw necrosis. The study is among the first to acknowledge that even short-term use of common oral osteoporosis drugs may leave the jaw vulnerable to devastating necrosis, according to a new report.

Many genes linked to various cancers do not appear to raise the risk of getting cancer after all, according to an analysis of hundreds of studies published on Tuesday.

Use of a non-steroidal anti-inflammatory drug (NSAID) for over five years may lessen a person's risk of developing cancer of the lower portion of the large bowel, study findings suggest. 
Food and Drug Administration does a double-take on bisphenol A

Back in August, the FDA declared that bisphenol A, a substance found in many different kinds of plastics (including baby bottles) was safe for use in products that touch human food and drink. However, this decision is now being reexamined. Bisphenol A can potentially mimic estrogen in the human body and it may be connected to heart and liver disease.
Even with the doubts over whether BPA is truly harmful, several manufacturers have begun to make and advertise baby bottles and other products as BPA-free.

A gene variation can make younger heart attack patients more prone to another heart attack, death or other heart problems if they receive the anti-clotting drug Plavix, a trio of new studies finds. 


New Anti-cancer Components of Extra-virgin Olive Oil Revealed

Good quality extra-virgin olive oil contains health-relevant chemicals, called "phytochemicals, that can trigger cancer cell death. New research sheds more light on the suspected association between olive oil-rich Mediterranean diets and reductions in breast cancer risk.
Javier Menendez from the Catalan Institute of Oncology and Antonio Segura-Carretero from the University of Granada in Spain led a team of researchers who set out to investigate which parts of olive oil were most active against cancer

A new study uncovers eleven gene variants associated with three blood lipids measured to determine cardiovascular disease risk: low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) and triglycerides. The discovery opens up new opportunities for nutrigenomics researchers looking for links between diet and genetics that will optimize health and lower chronic disease risk.
"Practically all genes related to lipid levels in the bloodstream respond to changes in the diet," says Jose M 


Nanotechnology may pose health risks

When radium was first discovered, no one thought it was dangerous. People painted it onto the hands of clocks to make them glow in the dark. Shoe stores used to have X-ray machines that people could use to see the bones in their feet. Roofers used to install asbestos shingles. Now, nanotechnology are the next big thing, and new research from Scotland is suggesting that carbon nanotubes may be as dangerous as asbestos.

Despite much hope generated by earlier studies, vitamins C and E and the element selenium have failed to reduce the incidence of prostate cancer. The disappointing news from two huge trials is reported online December 9 in the Journal of the American Medical Association.

A study published in the December issue of Cancer Prevention Research, a journal of the American Association for Cancer Research, suggests that selenium, a trace mineral found in grains, nuts and meats, may aid in the prevention of high-risk bladder cancer.
Researchers from Dartmouth Medical School compared selenium levels in 767 individuals newly diagnosed with bladder cancer to the levels of 1,108 individuals from the general population. Findings showed an inverse association between selenium and bladder cancer among women, some smokers and those with p53 positive bladder cancer

U.S. regulators remain concerned about serious risks from a class of asthma drugs and will ask outside advisers if approval for treating the lung disease should be revoked, documents released on Friday said.
Staff in the Food and Drug Administration's drug-safety office unanimously have recommended withdrawing clearance of all long-acting beta agonist drugs (LABAs) for children under eighteen amid evidence of an increased risk of asthma-related deaths and asthma attacks

Cancer researchers may have underestimated the power of some cancers to spread and cause new tumors, say U.S. researchers. 


Does Hormone Treatment Predispose Patients to Breast Cancer?

Breast cancer, the leading cause of death among women in France, is the most commonly occurring cancer in women. Sporadic breast cancer, which is non-hereditary, turns out to be the most widespread, representing 85 to 90% of all cases, but remains the least well-known. Researchers at CNRS and CEA (1), working with a team from Hôpital Saint-Louis (2), have just discovered the cause of 50% of sporadic breast cancers.
The results should also explain epidemiological studies which suggest that hormone treatment predisposes patients to breast cancer. The work is published in "Cancer Research 


Lifestyle may link depression and heart disease

The long-standing connection between depression and heart problems might be traceable to the fact that depressed people are less physically active than others, a new study of heart patients shows. A greater tendency in depressed people to smoke and to fail to take medications regularly may also play a role, researchers report in the Nov. 26 Journal of the American Medical Association 


Epilepsy drug may be risky for Asians

Treatment with certain epilepsy drugs may expose some Asian patients to serious skin reactions, federal health officials warned Monday.
The Food and Drug Administration said it is investigating whether medications like Dilantin, Phenytek and Cerebyx, which are used to control epileptic seizures, can lead to severe skin blisters and bleeding for some Asian patients.
Patients who test positive for a gene known as HLA-B1502 appear to be at increased risk of developing the skin problems, preliminary data indicate
