Cardiologists find old-fashioned physical exams just as good for assessing heart failure as new technology

Patient history and physical examination, traditionally the cornerstone diagnostic tool for medical care, may still be among the most accurate and cost-efficient methods to assess patients with congestive heart failure, UT Southwestern Medical Center researchers have found.

Genetic screening effective for initial HIV treatment

A major study from a team of researchers from Weill Cornell Medical College and Massachusetts General Hospital has found that a recent change to HIV-treatment guidelines recommending genetic screening is cost-effective under certain conditions. The new recommendation suggests conducting a genetic screening test prior to prescribing the drug abacavir, one of the preferred first-line drugs for the treatment for HIV-infected adults.

New research puts FDA under pressure over BPA

The results of a new study which has linked a chemical commonly used to make plastic containers, to human diseases, is adding to an already heated debate about he safety of such products.

Flies reveal immune cell response to tumour and tissue damage

Research with fruit flies has revealed more in common between simple cuts and scratches and the growth of tumours than might have been expected.

Who you fancy depends on your testosterone level

Researchers in Scotland have found that the hormone testosterone affects who women and men are attracted to.

Australian researchers have new model to predict long-term survival of critically ill patients

Researchers in Western Australia have come up with a new way of estimating the long-term survival of critically ill patients.

Prostate cancer genes behave like those in embryo

Gene activity in prostate cancer is reminiscent of that in the developing fetal prostate, providing further evidence that all cancers are not equal, Johns Hopkins researchers report. The finding could help scientists investigate how to manipulate the genetic program to fight a disease whose biology remains poorly understood despite more than half a century of investigation.

Breast cancer vaccine could protect against aggressive HER2-positive breast tumours

Women with a certain type of breast cancer have been given hope in the form of a vaccine which promises to eliminate the cancer tumours.

Study identifies immune response that enables TB bacteria to multiply, provides new target for TB drugs

Researchers have identified an immune system response to tuberculosis that enables TB bacteria to spread through the lungs, providing a new target for TB drug development, according to a study published Sunday in Nature Immunology, AFP/Washington Times reports.

Variations in cyclin D1 gene increase susceptibility to malignant melanoma

People who carry a particular genetic variant are at significantly increased risk of developing malignant melanoma, new research shows.

Parents of dying newborns need clearer explanation of options

Parent-doctor discussions about whether to maintain or withdraw life support from terminally ill or severely premature newborns are so plagued by miscommunication and misunderstanding that they might as well be in different languages, according to a small but potentially instructive new study from Johns Hopkins Children's Center reported in the September issue of Pediatrics.

Sun-damaged skin does not improve with estrogen treatments

Treating the skin with estrogen can stimulate collagen production-which improves the appearance of the skin-in areas not typically exposed to the sun, according to new research from the University of Michigan Health System.

Scientists identify ependymoma genes

Scientists at The University of Nottingham have isolated three important genes involved in the development of a type of childhood brain cancer. The breakthrough is revealed in a study published in the British Journal of Cancer.

An 'HIV-test' equivalent for early detection of lung cancer

A team of researchers led by Fred Hutchinson Cancer Research Center reports online today in the Journal of Clinical Oncology the validation of a potential "HIV-test" equivalent for the early detection of lung cancer. The test, which relies on immune-system signals, much like an HIV test, can detect the presence of lung cancer a year prior to diagnosis, long before symptoms appear.

Lung cancer in non-smokers is sixth biggest cancer killer

While lung cancer in smokers and former smokers is the biggest cancer killer by far, lung cancer in people who have never smoked is -- by itself -- the sixth biggest cancer killer in the United States.

Vaccine against HER2-positive breast cancer offers complete protection in lab

Researchers at Wayne State University have tested a breast cancer vaccine they say completely eliminated HER2-positive tumors in mice - even cancers resistant to current anti-HER2 therapy - without any toxicity.

Inherited one-hit gene mutation provides new opportunity for colon cancer prevention

More than 30 years ago, Alfred Knudson Jr., M.D., Ph.D., revolutionized the field of cancer genetics by showing that a person must lose both their paternal and maternal copies of a particular class of cancer-inhibiting genes, called tumor-suppressor genes, in order to develop cancer.

Scientists identify kidney failure susceptibility gene

Scientists at Johns Hopkins schools of Public Health and Medicine have, for the first time, identified variants in the gene MYH9 that are associated with increased risk for non-diabetic end stage renal disease (ESRD,) which is the near-loss of kidney function leading to either dialysis of transplant. MYH9, located on the 22 chromosome, is the first gene identified for common forms of kidney disease.

Speaking on a phone while driving puts drivers at significantly greater risk of collision

The Ontario Medical Association (OMA) has released findings about the significant impact that cellphone use has on driving safety. The research clearly shows that speaking on a phone while driving puts drivers at significantly greater risk of collision. Ontario's doctors want the provincial government to take action to protect the lives of all drivers and passengers.

Study shows high gum disease rates in rural Appalachia

Research on 445 families centered in two Pennsylvania towns and two West Virginia counties shows that 80 percent of adults suffer from more severe forms of periodontal disease, according to Richard Crout, D.M.D., Ph.D., an expert on gum disease and associate dean for research in the West Virginia University School of Dentistry.
