An international study, led by the University of Edinburgh, raises concerns that some patients may not be receiving the optimum medical treatment and follow-up care because doctors are misjudging the risk of a further heart attack.
Researchers looked at data taken from the Global Registry of Coronary Events that included more than 46,000 heart attack patients from 115 hospitals in 14 countries.
Researchers at the Moores Cancer Center at the University of California, San Diego (UC SD) in La Jolla have found evidence explaining why a common chemotherapy drug, cisplatin, may not always work for every cancer patient. They have shown that when a variant version of a key protein that normally causes cell death is active, patients may be resistant to the cancer-killing drug.
High impact activities such as jumping and skipping that can easily be incorporated into warm-ups before sports and physical education classes, have been shown to benefit bone health in adolescents.
The 10 minute school-based intervention, provided twice a week for about eight months, significantly improved bone and muscle strength in healthy teenagers compared to regular warm-ups.
Chevy Chase, MD—HIV-infected patients have a higher prevalence of fractures than non HIV-infected patients, across both genders and critical fracture sites according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
The Endocrine Society has released a new clinical practice guideline for the detection, diagnosis, and treatment of patients with primary aldosteronism. The guidelines appear in the September issue of the Journal of Clinical Endocrinology & Metabolism (JCEM), a publication of The Endocrine Society.

LEXINGTON, Ky. (Aug. 27, 2008) – A University of Kentucky ophthalmologist, along with a team of scientists, has discovered a genetic mutation that offers protection against a type of age-related macular degeneration (AMD), a disease of the eye that is the leading cause of blindness in adults over age 50.
Having discovered a genetic trigger for age-related macular degeneration, the leading cause of vision loss in people over 50, researchers report that an experimental state-of-the-art therapy for treating eye disease could adversely affect the vision of some patients with the "wrong" genetic makeup.
In a study that underscores the important role that individual genetic profiles will play in the development of new therapies for disease, a multi-institutional research team – led by Kang Zhang, MD, PhD professor of ophthalmology and human genetics at Shiley Eye Center at the University of California, San Diego, School of Medicine – has made two important discoveries related to age-related macular degeneration (AMD), the leading cause of blindness in adults over the age of 60.
WHAT: Events of the past year in HIV vaccine research have led some to question whether an effective HIV vaccine will ever be developed. In the August 28 edition of the New England Journal of Medicine, officials from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, examine the extraordinarily challenging properties of the virus that have made a vaccine elusive and outline the scientific questions that, if answered, could lead to an effective HIV vaccine.
ST. PAUL, Minn. – A new study shows that older people's mental skills start declining years before death, even if they don't have dementia. The study is published in the August 27, 2008, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A Temple University study finds fat in obese patients is "sick" when compared to fat in lean patients.
When our bodies don't work properly, we say we're sick. A study published in the September issue of Diabetes finds that the same could be said for fat tissue found in obese patients. The cells in their fat tissue aren't working properly and as a result, are sicker than cells found in lean patients' fat tissue.
AMES, Iowa -- Iowa State University researcher Robert Jernigan believes that his research shows proteins have controlled motions.
Most biochemists traditionally believe proteins have many random, uncontrolled movements.
Coventry, United Kingdom – August 27, 2008 – A new study in the journal Industrial Relations reveals that employee well-being is dependent upon the rank of an individual's wage within a comparison group, as opposed to the individual's absolute pay.
STANFORD, Calif. - Scientists at the Stanford University School of Medicine are shedding light on how type-1 diabetes begins.
Doctors have known the disease is caused by an autoimmune attack on the pancreas, but the exact trigger of the attack has been unclear. Now, a new study in mice implicates the immune signal interferon-alpha as an early culprit in a chain of events that upend sugar metabolism and make patients dependent on lifelong insulin injections.
