Combining short periods of leg compression with medications such as heparin is more effective at preventing blood clots in high-risk patients than using either preventative measure alone. A team of Cochrane Researchers believe that this 'belt and braces' approach can significantly decrease a patient's risk of deep vein thrombosis (DVT).

DVT can be fatal if the clot breaks free and travels to the lungs (pulmonary embolism). They can also cause severe leg swelling and ulcers – a condition known as post-thrombotic syndrome.

Women who have had early stage breast cancer surgically removed, and whose tumour cells are stimulated by the hormone oestrogen, can benefit from taking Luteinizing hormone releasing hormone (LHRH) antagonists, a Cochrane Systematic Review has concluded. This medication may be taken alone or alongside the use of tamoxifen.

Developing effective treatment regimes is important because approximately 30% of women diagnosed with early stage breast cancer eventually die of the disease.

Recent studies indicate that infusing hearts with stem cells taken from bone marrow could improve cardiac function after myocardial infarction (tissue damage that results from a heart attack). But in a recent systematic review, Cochrane Researchers concluded that more clinical trials are needed to assess the effectiveness of stem cell therapies for heart patients, as well as studies to establish how these treatments work.

Women who receive one to one instruction on how to contract the pelvic floor muscles and practice pelvic floor muscle exercises with health professional supervision are less likely to suffer urine leakage during or after pregnancy. A systematic review from The Cochrane Library suggests that these exercises are effective for preventing and treating incontinence.

A cream commonly used to treat burns may actually delay healing. In addition, despite the wide range of wound dressings available for burns, there is no consensus on the most effective alternative treatment, say Cochrane Researchers who carried out a systematic review of existing data.

Honey may reduce healing times in patients suffering mild to moderate burn wounds. A systematic review by Cochrane Researchers concluded that honey might be useful as an alternative to traditional wound dressings in treating burns.

"We're treating these results with caution, but it looks like honey can help speed up healing in some burns," says lead researcher Dr Andrew Jull, of the Clinical Trials Research Unit at the University of Auckland, New Zealand.

Scientists at the world-leading Department of Genetics at the University of Leicester – where the revolutionary technique of genetic fingerprinting was invented by Professor Sir Alec Jeffreys- are developing techniques which may one day allow police to work out someone's surname from the DNA alone.

Doctoral research by Turi King has shown that men with the same British surname are highly likely to be genetically linked. The results of her research have implications in the fields of forensics, genealogy, epidemiology and the history of surnames.

Researchers at Aberystwyth University, following a number of years of investment by the Biotechnology and Biological Sciences Research Council (BBSRC), have licensed ground-breaking research to a non-profit product development partnership working to develop new, more effective vaccines against Tuberculosis (TB). This development will give hope that significantly better prevention and treatment of TB will be available within the next few years.

One in four terminally ill patients in the State of Oregon who opt for physician assisted suicide have clinical depression and the Death with Dignity Act may not be adequately protecting them, concludes a study published on bmj.com today.

In 1997, the State of Oregon passed the Death with Dignity Act that allows physician assisted dying for terminally ill patients.

A protein that enables nerve cells to communicate with each other plays a key role in controlling the developing nervous system. Research into how that protein helps precise connections to form among nerve cells may provide a basis for eventual treatments for patients who suffer injuries to their nervous system, including spinal cord injury.

Older and younger patients with renal cancer derive similar benefit from sorafenib therapy and tolerate the drug equally well, according to a study published online October 7 in the Journal of the National Cancer Institute.

Women at elevated risk of breast cancer who had been randomly assigned to tamoxifen treatment and then developed estrogen receptor (ER)–negative breast cancer were diagnosed earlier than women who had been randomly assigned to take a placebo and then developed ER-negative disease, according to a study published online October 7 in the Journal of the National Cancer Institute.

Tamoxifen has been shown to reduce the risk of ER-positive breast cancer in women at high risk of disease. The drug does not alter the risk of ER-negative disease.

A comparison of two diagnostic methods used to detect deep vein thrombosis (DVT; a blood clot in a deep vein in the leg or thigh) of the lower extremities indicates that a simpler method, with wider availability, has rates of DVT detection that are equivalent to a more complex method, according to a study in the October 8 issue of JAMA.

Use of a class of medications for treating an enlarged prostate, known as 5-α reductase inhibitors, are not associated with an increased hip fracture risk, according to a study in the October 8 issue of JAMA.

An analysis of previous research indicates there is a lack of sufficient evidence that circumcision reduces the risk of human immunodeficiency virus (HIV) infection or other sexually transmitted infections among men who have sex with men, according to an article in the October 8 issue of JAMA.
