The 10 percent of children with sickle cell disease who are at risk for a stroke need ongoing blood transfusions to reduce their risk, according to a study at 25 sites in North America.
The National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH) has stopped early a clinical trial studying whether children with sickle cell anemia at high risk for stroke could at some point after a minimum of 30 months safely stop receiving the periodic blood transfusions that prevent strokes. The study found a return to high risk of stroke in children who stopped receiving the transfusions. The NHLBI is issuing a clinical alert on the study's results to inform physicians.
An experimental drug under development by Bristol-Myers Squibb is showing early promise in reversing the signs and symptoms of patients whose chronic myeloid leukemia failed to respond to Gleevec, which is considered the standard of treatment for the disorder.
A biocide found in many shampoos and hand lotions and widely used in industrial settings inhibits the development of neuron structures that are essential for transmitting signals between cells, according to a University of Pittsburgh study presented today Cell Biology 2004. Prolonged exposure to low levels of methylisothiazolinone restricted growth of axons and dendrites of immature rat nerve cells in culture and may have potentially damaging consequences to a developing nervous system.
The University of Texas M. D. Anderson Cancer Center offers these news items presented at the annual meeting of the American Society of Hematology (ASH).
A University of Oregon researcher who believes consumers should be partners in improving the nation's health care system will serve on the National Advisory Council for Healthcare Research and Quality (NACHRQ).
Seven papers that expand upon recent research into the origin of tetrapods and their invasion of the land during the Devonian period appear in the September/October 2004 issue of Physiological and Biochemical Zoology.Topics in this state-of-the-art issue range from the fish-tetrapod fossil record to diverse aspects of the behavior, physiology, biochemistry, and ecology of the extant fish species that use either or both terrestriality and air breathing.
Rob DeSalle and Michael Yudell, authors of .Welcome to the Genome: A User.s Guide to the Genetic Past, Present, and Future,. will be speaking at the American Museum of Natural History on Thursday, December 16, at 7 p.m.
University at Buffalo researchers, working with an Amherst, N.Y., startup company called Esensors have developed a unique, real-time patient dose-tracking system, which lets physicians know when the accumulated radiation dose is approaching a dangerous threshold.
People could be exposed to antibiotic-resistant bacteria from breathing the air from concentrated swine feeding facilities, according to researchers at the Johns Hopkins Bloomberg School of Public Health. They detected bacteria resistant to at least two antibiotics in air samples collected from inside a large-scale swine operation. The study adds to the understanding of various pathways in which humans can be exposed to antibiotic-resistant bacteria and is published in the online edition of Environmental Health Perspectives.
Parkinson's disease may be caused by an environmental-genetic double whammy on the neurons that produce dopamine, the neurotransmitter that controls body movement, a new study by researchers at the University at Buffalo has shown.
Pain management for nursing home residents can dramatically improve using a comprehensive, collaborative improvement process - one that quickly changes how staff assess and treat pain. This is the conclusion of a new study conducted by researchers at Brown Medical School and Quality Partners of Rhode Island and published in the Journal of the American Geriatrics Society.
Researchers at UT Southwestern Medical Center at Dallas have utilized an animal model to trace how the virus that causes AIDS in humans may enter and spread throughout the body following an oral exposure.By innoculating monkeys with SIV, the simian version of HIV, scientists traced which tissues in the mouth and digestive tract were infected during the first week. They traced which organs and lymph nodes were first infected and uncovered likely infection routes.
A successful method for healing spinal injuries in dogs has been developed by Purdue University researchers, offering hope for preventing human paralysis. Lab tests have shown that an injection of a liquid polymer known as polyethylene glycol (PEG), if administered within 72 hours of serious spinal injury, can prevent most dogs from suffering permanent spinal damage.
A new study from Ohio State University provides the first laboratory evidence that certain antioxidants found in dark leafy green vegetables can indeed help prevent cataracts. Vitamin manufacturers often add the antioxidants lutein and zeaxanthin to their products, but until now there has been no biochemical evidence to support the claim that these substances help protect the eyes.
You are cordially invited to the Cardiac Institute's 11th Annual Cardiac Symposium at Maimonides Medical Center.
You are cordially invited to "Towards the Establishment of Pediatric Stroke Trials" Conference sponsored by Maimonides Infants and Children's Hospital, the International Pediatric Stroke Study (IPSS), and the National Institute of Neurological Diseases and Stroke (NINDS). The research conference aims to develop clinical studies to do research in newborn and childhood stroke.
Low-income, ethnic minority populations may be more vulnerable to obesity because of inadequate access to healthy foods, according to a study from the University of Houston College of Education. Rebecca Lee, assistant professor of health education and lead researcher, examined healthful food availability in urban low-income and urban high-income neighborhoods. She was awarded a two-year, $110,000 grant from the American Heart Association Heartland Affiliate to study the issue.
In a comprehensive study released today by Population Action International (PAI) - an independent policy and research organization based in Washington, D.C. - the United States ranks 16th and receives a 'C' on a list of 21 donor countries graded according to their financial and political support for international reproductive health and population programs.
Scientists at the Vaccine and Gene Therapy Institute at Oregon Health & Science University have made a discovery that helps explain why our immune system worsens with age. The scientists hope this new information can be used to better protect the elderly from infectious diseases by finding ways to slow or stop the degradation of the immune system.
A new research method that quantifies people's quality of life -- beyond how much money they make -- could lead to a national index of well-being, similar to key measures of economic health.
Doctors and their patients have puzzled over why certain cholesterol-lowering drugs work better in some people than others. In research results published in the December issue of the journal Nature Genetics, the common minnow helps provide an answer.
A good night's sleep may be the remedy for a bad day at work, suggests a new University of Florida study on the unexplored relationship between job satisfaction and the shifting moods of employees.
Stories about the possible health and environmental dangers of nanotechnology, the ethical and moral implications of a "forgetting" drug, the quest for ways to halt the aging clock, and the legal dilemmas posed by new artificial reproductive technologies are the subjects of this year's winners of the Science-in-Society award, which is conferred by the National Association of Science Writers (NASW).
A study published in the journal Epilepsia shows higher unemployment and a lower health-related quality of life (QoL) in patients who had epilepsy as a child.
