Tripling clopidogrel dosage improves platelet reactivity in cardiac patients

Among patients with stable cardiovascular disease who have a genetic variation that diminishes the response to the antiplatelet drug clopidogrel, tripling the standard daily dosage of this medication resulted in improved platelet reactivity, according to a study appearing in JAMA.

Flu strains migrate back and forth between different regions of the world

Influenza researchers have found that flu strains migrate back and forth between different regions of the world, evolving along the way. This is contrary to the common belief that flu strains from the tropics are the source of global seasonal epidemics.

UTHealth study: Heart attack patients who call 911 are sicker

Cardiologists are quick to point to statistics showing that the "door-to-balloon" treatment time for heart attack patients has dropped significantly in the past few years. But a retrospective study reveals that those who call 911 are most likely to have suffered a severe heart attack and despite receiving treatment quickly, they are still dying at unacceptable rates, say researchers at The University of Texas Health Science Center at Houston.

Supervised exercise more effective than stenting or medication for PAD

Supervised exercise was shown to be more effective than stenting or medication for improved walking ability in patients with peripheral artery disease. The findings from a national study were reported today at the 2011 American Heart Association Scientific Sessions meeting.

New 2-DG-ABT combination cancer therapy triggers apoptosis

Researchers at the University of California, San Diego School of Medicine and Kyushu University Medical School say a novel combination of a specific sugar molecule with a pair of cell-killing drugs prompts a wide variety of cancer cell types to kill themselves, a process called apoptosis or programmed cell death.

Dipyrone may reduce brain damage after stroke

An older nonsteroidal anti-inflammatory drug (NSAID) called dipyrone may offer a new approach to reducing injury to brain tissue after a stroke, according to a study in the October issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

CDCs can increase healthy heart muscle cells in patients with ischemic heart disease

Healthy, new heart cells have been generated by animals with chronic ischemic heart disease after receiving stem cells derived from cardiac biopsies or "cardiospheres," according to research conducted at the University at Buffalo School of Medicine and Biomedical Sciences.

Researchers to begin drug development projects for rare and neglected diseases

Researchers will begin drug development projects for rare and neglected diseases that include potential treatments for a musculoskeletal disorder, a cognitive dysfunction disorder, a virus that affects the central nervous system of newborns, a parasitic worm infection, a form of muscular dystrophy and a rare lung disease.

New computer chip models how neurons communicate with each other at synapses

For decades, scientists have dreamed of building computer systems that could replicate the human brain's talent for learning new tasks. MIT researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain's neurons adapt in response to new information. This phenomenon, known as plasticity, is believed to underlie many brain functions, including learning and memory.

EPO-secreting engineered vessels could reverse anemia

Patients who rely on recombinant, protein-based drugs must often endure frequent injections, often several times a week, or intravenous therapy. Researchers at Children's Hospital Boston demonstrate the possibility that blood vessels, made from genetically engineered cells, could secrete the drug on demand directly into the bloodstream.

Xarelto (rivaroxaban) shows success as blood thinner in acute coronary syndrome

A new anti-blood clotting drug – Xarelto (rivaroxaban) has shown clinical success. It may help people with “acute coronary syndrome” lower their risk of death, subsequent heart attack or stroke, a new study finds. Acute coronary syndrome is term that includes people with angina or prior history of heart attack.

Eliminating drug co-pays improves medication adherence in heart attack patients

The use of specific medications following a heart attack has been shown to reduce cardiovascular events and mortality, however; while highly effective, the rate of adherence to these medications is poor. Researchers from Brigham and Women's Hospital (BWH) evaluated whether eliminating co-payments for these medications would increase adherence and improve outcomes in patients who have had a heart attack.

Scientists find new tools to help understand neurodevelopmental disorders

Research released today shows that scientists are finding new tools to help understand neurodevelopmental disorders like autism and fragile X syndrome. These studies show in new detail how the brain's connections, chemicals, and genes interact to affect behavior.

State roundup: Md.'s medical home; N.Y. malpractice action; Texas nursing homes

Instead of a doctor seeing patients mostly when they're sick - and the physician is getting paid for that visit or service - this program gives financial rewards to practices that use a team of doctors, nurses and other staff to treat the whole person on a continuing basis, not just for one illness. ... The state initiative is among dozens of public and private experiments across the country that are trying to fundamentally change the way doctors practice medicine.

New clues about connections among fat, inflammation and insulin resistance

In a new study, scientists report that they substantially curbed weight gain, improved metabolism, and improved the efficacy of insulin in mice by engineering them to express a specific human enzyme in their fat tissue. Although the obesity prevention came at the significant cost of widespread inflammation, the research offers new clues about the connections among obesity, insulin resistance and type 2 diabetes, and inflammation.

Bayer and J&J’s blood thinner drug triumphs at late phase clinical trial

Drug makers Bayer AG and Johnson & Johnson’s new blood clot preventing drug can provide life-saving benefits at very low doses in patients who suffer from acute coronary syndrome finds a new clinical trial.

BIDMC researcher says improvement in survival rates best 'since introduction of aspirin'

An oral anti-clotting drug, when added to standard medical treatment for acute coronary syndrome, lowered the risk of death, heart attack or stroke an average of 16 percent, according to research presented at the American Heart Association's Scientific Sessions.

Alcohol consumption may increase risk of benign breast disease in adolescents

Breast cancer patients often wonder what their daughters might do to reduce their risk of also developing cancer. Are there dietary intakes or behaviors that can be modified by their daughters to lower their own chances of getting the disease? A new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society, sought information relevant to this question.

Novel gene mutation may increase risk of inherited and sporadic cases of MM

A major international study has identified a novel gene mutation that appears to increase the risk of both inherited and sporadic cases of malignant melanoma, the most deadly form of skin cancer.

Researchers retrace evolution of unusual bacterial infection

Researchers at Harvard Medical School and Children's Hospital Boston have retraced the evolution of an unusual bacterial infection as it spread among cystic fibrosis patients by sequencing scores of samples collected during the outbreak, since contained.
