Cancer treatment is first to directly target tumor blood vessels in patients
A clinical trial has for the first time proven that an antibody called J591 specifically targets an antigen found in high amounts on both prostate tumors and on blood vessels of all solid tumors, according to a study by medical researchers at NewYork-Presbyterian Hospital/Weill Cornell Medical Center in New York City.
Regulation of heart procedures falls short of expectations
Certificate of Need, a form of state government regulation designed to keep mortality rates and healthcare costs down, appears to do neither with regard to two widespread heart procedures, said a health economics researcher at Baylor College of Medicine and Rice University. The findings are reported in an article appearing in today's online edition of the International Journal of Health Care Finance and Economics. more
Reactions to 'false-positive' prostate cancer screenings assessed
Men who get a "false-positive" prostate cancer result -- an abnormal screening test followed by a biopsy indicating no evidence of cancer -- appear more likely to worry about their subsequent risk of cancer and report more problems with sexual function compared to men with normal screening results, according to a University of Iowa study. more
Erectile dysfunction drugs may trump nitroglycerin for heart protection
Erectile dysfunction drugs may be better than nitroglycerin in protecting the heart from damage before and after a severe heart attack, Virginia Commonwealth University researchers report today. more
Antidepressants improve post-stroke 'thinking outside the box'
Antidepressant treatment appears to help stroke survivors with the kind of complex mental abilities often referred to as "thinking outside the box," according to a University of Iowa study.
Genes and stressed-out parents lead to shy kids
New research from the Child Development Laboratory at the University of Maryland shows that shyness in kids could relate to the manner in which a stress-related gene in children interacts with being raised by stressed-out parents. more
Rare cell prevents rampant brain activity
One of the mysteries of the brain is how it avoids ending up in a state of chaos, something which happens only on exceptional occasions, when it can lead to epileptic fits. Scientists at Karolinska Institutet have now uncovered a new mechanism controlling how the brain keeps its neuronal activity in check. more
Hot tubs hurt fertility, UCSF study shows
Exposure to hot baths or hot tubs can lead to male infertility, but the effects can sometimes be reversible, according to a new study led by a University of California, San Francisco urologist.
Whole-grain breakfast cereal associated with reduced heart failure risk
Eating whole-grain breakfast cereals seven or more times per week was associated with a lower risk of heart failure, according to an analysis of the observational Physicians’ Health Study. Researchers presented findings of the study today at the American Heart Association’s 47th Annual Conference on Cardiovascular Disease Epidemiology and Prevention. For the present study, breakfast cereals that contain at least 25 percent oat or bran content were classified as whole grain cereals. more
Pregnant smokers raise their child's risk of stroke, heart attack
Women who smoke during pregnancy can cause permanent vascular damage in their children — increasing their risk for stroke and heart attack, researchers said today at the American Heart Association’s 47th Annual Conference on Cardiovascular Disease Epidemiology and Prevention. more
Hispanic women at higher risk for heart disease
Hispanic women’s heart disease risk is comparable to the heart disease risk level of Caucasian women who are about a decade older. This disagrees with a long-held belief that Hispanic women have less heart disease than Caucasian women, researchers reported today at the American Heart Association’s 47th Annual Conference on Cardiovascular Disease Epidemiology and Prevention. more
Treating male infertility with stem cells
New research has examined the usefulness of bone marrow stem cells for treating male infertility, with promising results. The related report by Lue et al, “Fate of bone marrow stem cells transplanted into the testis: potential implication for men with testicular failure,” appears in the March issue of The American Journal of Pathology.
New details in schizophrenia treatment trial emerge
Two new studies from the Clinical Antipsychotic Trials for Intervention Effectiveness (CATIE) provide more insights into comparing treatment options, and to what extent antipsychotic medications help people with schizophrenia learn social, interpersonal and community living skills. The new studies are published in the March 2007 issue of the American Journal of Psychiatry. CATIE, a $42.6 million, multi-site study, was funded by the National Institutes of Health’s National Institute of Mental Health (NIMH). more
Review of 1918 pandemic flu studies offers more questions than answers
Scientists and public health officials, wary that the H5N1 avian influenza virus could trigger an influenza pandemic, have looked to past pandemics, including the 1918 “Spanish Flu,” for insight into pandemic planning. However, in a Journal of Infectious Diseases review article now posted online, David M. Morens, M.D., and Anthony S. Fauci, M.D., of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, conclude that studies of the 1918 influenza pandemic, which killed some 50 to 100 million people around the globe, have so far raised more questions than they answer. more
