Aurora, COLO. -- A study published in the July 2009 issue of the Journal of Thoracic Oncology revealed that internet-based lung cancer information was of a higher quality in the United States (US) than in Japan. Dr. Yasushi Goto of the National Cancer Center Hospital in Tokyo and his team of researchers from both the US and Japan evaluated 150 Web sites and determined noticeable differences in the quality and type of information on lung cancer available over the internet in the two countries.

Transcriptomic tests have uncovered the protein composition of venom from the Scorpiops jendeki scorpion. Researchers writing in the open access journal BMC Genomics have carried out the first ever venom analysis in this arachnid, and discovered nine novel poison molecules, never before seen in any scorpion species.
Measurement of known biomarkers of cardiovascular disease slightly improves the ability to predict future heart attack or stroke in healthy individuals, but not enough to change preventive therapies. The study led by investigators at Massachusetts General Hospital (MGH) and Lund University in Sweden appears in the July 1 Journal of the American Medical Association.

An analysis of the association between genetic variations of the inflammation biomarker C-reactive protein (CRP) with coronary heart disease failed to support a causal association, according to a study in the July 1 issue of JAMA.

Local laws, insurance reimbursement and public misperceptions impede emergency medical services (EMS) workers from using best resuscitation practices, according to a study reported in Circulation: Cardiovascular Quality and Outcomes.
Less than half of local EMS systems follow national guidelines on transporting cardiac arrest patients and terminating unsuccessful out-of-hospital resuscitation efforts, said researchers who conducted three small focus groups at the 2008 National Association of Emergency Medical Services Physicians meeting in Jacksonville, Fla.
A protein used by doctors to indicate a patient's risk of coronary heart disease may have drug developers barking up the wrong treatment tree, according to the authors of a study published today in the Journal of the American Medical Association (JAMA). Their research suggests that C-reactive protein, an enticing target for scientists working on new treatments for coronary heart disease, may not have a role in causing the disease, even though it is a predictive marker.
Lyme disease in theU.S. is caused by the tick-borne bacteria Borrelia burgdorferi and usually begins with a skin lesion, after which the bacteria spread throughout the body to the nervous system, heart or joints. About 60 percent of untreated individuals develop arthritis, which affects the knees in particular. Lyme disease usually responds well to antibiotic therapy, but in rare cases arthritis can persist for months or years after treatment, a rare condition known as antibiotic-refractory Lyme arthritis.
Boston, Ma. – June 30, 2009 – The potential role of periodontitis, an inflammatory disease of the gums, in the risk of cardiovascular disease, particularly ischemic stroke, has received growing attention during the last decade. A new study is the first prospective cohort study to use clinical measures of periodontitis to evaluate the association between this disease and the risk of cerebrovascular disease. The study is published in Annals of Neurology, the official journal of the American Neurological Association
Treatment with anti-tumor necrosis factor (TNF) agents is recognized as a risk factor for tuberculosis (TB) in patients with immune-mediated inflammatory diseases such as rheumatoid arthritis, ankylosing spondylitis, Crohn's disease, psoriatic arthritis and psoriasis. Most TB cases develop as a result of reactivation of a latent TB infection, and health authorities worldwide recommend screening for latent TB and treating patients before initiating anti-TNF treatment.
WASHINGTON -- A new report from the Institute of Medicine recommends 100 health topics that should get priority attention and funding from a new national research effort to identify which health care services work best. It also spells out actions and resources needed to ensure that this comparative effectiveness research initiative will be a sustained effort with a continuous process for updating priorities as needed and that the results are put into clinical practice.
The equipment used for biomedical research is shrinking, but the physical properties of the fluids under investigation are not changing. This creates a problem: the reservoirs that hold the liquid are now so small that forces between molecules on the liquid's surface dominate, and one can no longer shake the container to mix two fluids. Instead, researchers must bide their time and wait for diffusion to occur.
A new report issued by the International Osteoporosis Foundation (IOF) and published in the scientific journal Osteoporosis International1, shows that populations across the globe are suffering from the impact of low levels of vitamin D. The problem is widespread and on the increase, with potentially severe repercussions for overall health and fracture rates.
PHILADELPHIA – Physiological changes associated with the metabolic syndrome may play a role in the risk of postmenopausal breast cancer, according to study results published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
The metabolic syndrome, or insulin resistance syndrome, consists of a constellation of factors including abdominal obesity, high blood glucose levels, impaired glucose tolerance, abnormal lipid levels and high blood pressure.
PHILADELPHIA - As scientists continue to decode the human genome and the information becomes publicly available, private companies that offer online genetic testing are multiplying. Scientists at the National Institutes of Health were concerned that perhaps these tests posed a risk.
