Female heart attack patients undergoing angioplasty have a higher risk of death than men, but stenting may improve their outcomes, according to a study reported in Circulation: Journal of the American Heart Association.
A new analysis of the CADILLAC (Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications) trial examined gender differences in outcomes after treatment with angioplasty compared to stenting, with and without the antiplatelet agent abcix
Laboratory technicians battling cancer want to improve diagnosis and treatment of the disease. But they are drowning in data from modern biological techniques. New Web-based software – validated in three European oncology hospitals – can extract potentially life-saving knowledge from such data in minutes.
In Europe, cancer is the second cause of death; worldwide it accounts for 23.5 per cent of all deaths. The race to beat this disease increasingly depends on groundbreaking bioinf
Researchers have discovered that antidepressant drugs such as Prozac not only affect levels of the neurotransmitter serotonin in the brain, but also “hijack” dopamine signaling as well–causing it to launch serotonin signals. Their findings offer new insight into how Prozac and other “selective serotonin uptake inhibitors” (SSRIs) work and how they might cause problems in patients taking them.
SSRIs perform their antidepressant function by increasing the concentration of seroton
The pathology of rheumatoid arthritis within the first few months after symptom onset is distinct from that of the early phases of other inflammatory joint diseases and also of established rheumatoid arthritis. New research published today in Arthritis Research & Therapy found that very early rheumatoid arthritis is characterised by a distinct profile of T cell, macrophage and stromal cell related cytokines in synovial fluid.
This finding of a distinct phase of rheumatoid arthr
Stem cell research and artificial lung technology presented at ISHLT meeting today (6-Apr-2005)
Promising new technology may extend the life of a failing organ for patients suffering from heart or lung disease while they wait for a donor organ. The use of stem cells may eliminate the need for a transplant and even eradicate heart disease in patients. Research and discussion will be presented today during symposia at the International Society for Heart and Lung Transplantation (ISH
According to a study published in the American Gastroenterological Association (AGA) journal Clinical Gastroenterology and Hepatology, a nutritionally complete oral supplement enriched with fish oil, soluble fiber and antioxidants reduces reliance on traditional therapies for people with ulcerative colitis. Moreover, people who took the oral supplement were less likely to start corticosteroid drug therapy, which has many long-term side effects.
“Our study proves that an oral supp
The risk of HIV transmission via heterosexual intercourse is highest early in the course of HIV infection, before most infected people know their HIV status, according to a new study published in the May 1 issue of The Journal of Infectious Diseases, now available online.
Conducted by a group of investigators led by Maria J. Wawer of Columbia University, the study is the first to present empirical data showing that the rate of heterosexual HIV transmission per coital act varies
Dr. Eric McAdams, who led the PhD research project alongside Peter O’Hare and Gillian McCullough, is available to discuss the Impedimap technology and its commercial development.
The key to Impedimap is that the system can be used to provide instant, accurate feedback on wounds such as venous leg ulcers, diabetic ulcers and sores, burns and surgical wounds – all without removing the dressing. It works using an electrode array system built into the bandage, which builds up
As Americans’ waistlines continue to expand, contributing to a burgeoning epidemic of type 2 diabetes, the scientific jury is in and the verdict is clear: weight loss and increased physical activity is directly related to improved diabetes control. To help Americans fight the dramatic increase in type 2 diabetes, Joslin Diabetes Center has crafted new nutrition and physical activity guidelines for overweight and obese individuals with type 2 diabetes and those at risk for developing diabetes
A drug prescribed for the prevention of osteoporosis reduced women’s risk of mild cognitive impairment by 33 percent in a worldwide clinical trial led by researchers at San Francisco VA Medical Center (SFVAMC).
The drug, raloxifene, modulates the activity of the hormone estrogen. The finding was published in the April 2005 issue of the American Journal of Psychiatry.
Mild cognitive impairment (MCI) affects more than one-third of women and one-fifth of men aged 65 a
Study says sleep improves by more than a third
Sleep, a vital ingredient in life, can sometimes become difficult as humans get older. But a recent study by researchers at Case Western Reserve University’s Frances Payne Bolton School of Nursing and the Buddhist Tzu-Chi General Hospital in Taiwan shows that listening to soft music at bedtime will help older adults sleep better and longer.
The research, published in the February 2005 edition of The Journal of Advanced Nur
A team of scientists from Aston University in Birmingham, UK have made a discovery that could lead to new ways of treating children who develop a particularly aggressive form of cancer. The research was funded by the Association for International Cancer Research (AICR).
Craniopharyngioma tumours cause severe headaches, vomiting, disturbed vision and growth defects. They are usually diagnosed in babies and very young children, and cause one in ten of all childhood brain tumours.
Intense light pulses can kill 99.999% of food poisoning bugs in just six bursts, say researchers from Strathclyde University today (Wednesday, 06 April 2005) presenting at the Society for General Microbiology’s 156th Meeting at Heriot-Watt University, Edinburgh.
The dangerous food poisoning bacteria Listeria monocytogenes can be effectively cleared from contaminated kitchen surfaces, water treatment plants, hospital operating theatres, and even from the air by using puls
Circulation article describes Viagra’s ability to stabilize
Virginia Commonwealth University researchers have found that the popular impotence drug Viagra prevents damage to the heart from a potent chemotherapeutic agent frequently used in the treatment of breast cancer, leukemia and sarcomas.
In the April 5 issue of Circulation: Journal of the American Heart Association, researchers demonstrated for the first time that administration of clinically relevant doses
Two University of Kentucky researchers continue their work with a vaccine to prevent lung cancer recurrences in patients following primary treatment of the disease.
Vaccines are being developed with the hope of reducing the unacceptably high rates of recurrence and disease progression seen in the treated lung cancer population. The cancer vaccine program is now enrolling a second cohort of subjects to study the effects of the vaccine in lung cancer patients. The vaccine is deliver
New mothers who are mildly iron deficient — a common result of childbirth among women who don’t take their vitamins — are less emotionally available or in tune with their babies, a Penn State study has shown.
Dr. Laura Murray-Kolb, a National Institute of Mental Health post-doctoral fellow in child development at Penn State who led the study says, “Earlier research had shown that anemic women may experience post-partum depression and that women with moderate iron deficiency h
