Despite previous studies suggesting the contrary, statins (cholesterol-lowering drugs) may not prevent blood clots (venous thrombo-embolism) in adults, according to a large analysis by international researchers published in this week's PLOS Medicine. In 2009, an additional analysis of data from a randomized controlled trial called the JUPITER trial reported that the statin rosuvastatin halved the risk of venous thromboembolic events among apparently healthy adults.

The majority of observational studies have shown that alcohol intake, especially heavy drinking, increases a number of upper-aero-digestive tract (UADT) and other cancers, and even moderate drinking is associated with a slight increase in the risk of breast cancer. A meta analysis published in the Annals of Oncology compares the effects between light drinkers (an average reported intake of up to 1 typical drink/day) versus "non-drinkers" in terms of relative risks for a number of types of cancer.

The power of taxane-based chemotherapy drugs are misunderstood and potentially underestimated, according to researchers at Weill Cornell Medical College in the September 15 issue of the journal Cancer Research. Most physicians and investigators believe that taxane chemotherapy (paclitaxel, docetaxel and cabazitaxel) just does one thing - stop a cancer cell from dividing - but the scientists have revealed it acts much more powerfully and broadly, especially against prostate cancer.

The antidiabetic drug metformin is not prescribed for patients with reduced kidney function because the risk of adverse effects has been regarded as unacceptably high. A study at Sahlgrenska Academy, Sweden, has found that the risks have been substantially overrated. As a result, many more patients with diabetes may be able to enjoy the benefits of the medication.

A new study by researchers at Weill Cornell Medical College shows combining two already-FDA approved drugs may offer a new and potent punch against diseases in which blood vessel growth is abnormal - such as cancer, diabetic retinopathy, macular degeneration and rheumatoid arthritis.

A nationwide consortium of scientists has reported the first comprehensive genetic analysis of squamous cell carcinoma of the lung, a common type of lung cancer responsible for about 400,000 deaths each year.

An international team of researchers, led by scientists at the University of California, San Diego and Yale University schools of medicine, have identified a form of autism with epilepsy that may potentially be treatable with a common nutritional supplement.
