Type 2 diabetes and depression can be a fatal mix

Patients whose type 2 diabetes was accompanied by minor or major depression had higher mortality rates, compared to patients with type 2 diabetes alone, over the three-year period of a recent study in Washington state.

Rate of weight gain, not the degree of fatness at any one time, which is the main predictor of future problems

Research published today indicates that the risk of heart disease in adulthood is more strongly related to how quickly children gain weight between the ages of two and eleven than their actual body weight at any particular age. Scientists believe this is linked to differences in insulin processing in later life.

Bouncing helicases possibly play a preventative role in keeping the genome intact

Researchers studying how proteins called helicases travel along strands of DNA have found that when the proteins hit an obstacle they snap back to where they began, repeating the process over and over, possibly playing a preventative role in keeping the genome intact.

New diabetes trial - largest diet and exercise study of its kind

Doctors from the University of Bristol are looking for volunteers who have recently been diagnosed with Type 2 diabetes to take part in the largest diet and exercise study of its kind. The study will be based in local hospitals across the Southwest.

Way now clear for use of costly breast cancer drug throughout UK

Health managers in the UK have virtually been ordered to pay for the drug Herceptin for women with an aggressive form of breast cancer in its early stages.

Study provides insight into cellular defenses against genetic mutation

With their latest discovery, researchers have significantly advanced the understanding of how human cells protect themselves from constant and potentially destructive changes in gene expression.

Preventing pneumonia in children helps prevent pneumonia in older adults

The incidence of pneumonia among older adults has decreased substantially, linked to the introduction of a pneumonia vaccine for children in 2000, according to a study in the October 26 issue of JAMA: The Journal of the American Medical Association.

Testosterone may improve women's sex lives after menopause

The addition of testosterone to hormone therapy in women after menopause enhances their sexual function. However, it may also reduce HDL cholesterol (the "good" cholesterol) in women, according to a systematic review of current evidence.

Protein Oct-6 is not a biological marker for schizophrenia

The protein Oct-6 is not a biological marker for schizophrenia. The results of a study published today in the open access journal BMC Psychiatry contradict previous findings and show that Oct-6, a protein involved in neurodevelopment, is normally expressed in the adult brain and cannot be used to identify patients with schizophrenia.

Study shows cystic fibrosis gene mutation a risk factor for young-onset pancreatic cancer disease

Mayo Clinic researchers have found the risk of developing pancreatic cancer at a young age (under 60) to be twice as high for people who carry a mutation of the gene that causes cystic fibrosis, compared to noncarriers. Results of a pilot and follow-up study were reported Oct. 14, 2005, online in the journal Gut.

Gene found only in men is altered by a chemical process, which is in turn linked to aggressive forms of melanoma

New scientific evidence that may shed light on why men are more likely than women to develop aggressive forms of skin cancer has been published in Carcinogenesis.

Hepatitis C linked to illegal blood donation in China

Research in a rural province of central China has documented that illegal blood donation practices led to high hepatitis C virus (HCV) infection rates in blood and plasma donors during the 1980s and early 1990s, and that failure to screen for HCV in transfusion recipients increased their risk of infection as well

Molecule P-glycoprotein (Pgp), may help reduce risk of Alzheimer's

A molecule that has long been an obstacle to cancer chemotherapy and drug treatments for brain disorders may soon become an ally in the fight against Alzheimer's disease, according to researchers at Washington University School of Medicine in St. Louis and the University of Rochester.

Retiring early is not linked to longer life

There is a widespread perception that early retirement is associated with longer life expectancy and later retirement is associated with early death. But no consensus has been reached on the effect of early retirement on survival.

Identification of a single chromosome region linked to specific language impairment

Researchers at the University of Toronto (U of T), Capital Health's Stollery Children's Hospital in Edmonton, Toronto's Hospital for Sick Children and their international collaborators have discovered a genetic abnormality that causes a type of language impairment in children

Access to genetic counseling and testing are an important part of cancer control

Ten years after the identification of the first breast cancer susceptibility genes so few high-risk minority women have received genetic counseling or testing that the standard methods of calculating risk have not been validated in these groups and the results of genetic testing can still produce surprises.

Controlling antibiotic-prescribing practices in hospitals

Plenty of promising strategies exist to control antibiotic-prescribing practices, but no single method emerges as the best for hospital patients, according to a new review of studies.
