There are no guideliInnes on whether a noninvasive method of measuring carbon dioxide from patients' exhalations, known as end-tidal capnography, is as effective as drawing blood through a child's artery. This study published in JAMA found that measuring the carbon dioxide level through an artery is still the most accurate diagnostic for pediatric brain trauma.
Researchers at Massachusetts General Hospital have taken a key step forward in developing a new, possibly safer contrast agent for use in MRI exams.
A FAPESP-funded study with results published in The Lancet Infectious Diseases has identified markers capable of predicting mortality in patients with symptoms of yellow fever, potentially helping to prevent the development of severe conditions.
Travis Dunckley, a researcher at the ASU-Banner Neurodegenerative Disease Research Center, and Christopher Hulme, D. Phil, medicinal chemist at the Arizona Center for Drug Discovery based at the UA College of Pharmacy, are exploring a small molecule drug known as DYR219. The promising therapy, while still in the experimental stages, may succeed where other treatments have failed, and could be effective against a range of neurodegenerative illnesses in addition to Alzheimer's.
An increased concentration of cardiac troponin (a regulatory protein) in the blood after prolonged walking is associated with an increased risk of cardiovascular disease and premature death. This was the conclusion of a study involving 725 participants in a long-distance walking event (Nijmegen Four Days Marches) that was published in the journal Circulation.
Early findings from two major federally funded initiatives aimed at accelerating the development and dissemination of health care innovation in the United States were published today as a special supplement to the Annals of Family Medicine. The collective body of work, funded by the Centers for Medicare and Medicaid Services, will help inform how the United States will support medical practice transformation and community health improvement efforts in the years ahead.
A drug used to treat attention-deficit/hyperactivity disorder (ADHD) appears to affect the development of the brain's signal-carrying white matter in children with the disorder, according to a new study. The same effects were not found in adults with ADHD.
Doctors urgently need a fast and accurate test for diagnosing urinary tract infections (UTIs) to reduce overprescribing of antibiotics, according to health researchers.
Ninety-nine percent of cervical cancers are caused by human papillomavirus (HPV). More than 200 HPVs associated with varying degrees of cancer risk complicate diagnosis and treatment. A report in The Journal of Molecular Diagnostics describes a new 'two-for-one' diagnostic approach that not only detects the type of HPV infection, but also indicates precancerous markers. This test may improve the ability to diagnose the riskiest forms of HPV infection, provide rapid results at low cost, and help avoid unnecessary diagnostic procedures.
A new review to help physicians manage the risk of ovarian cancer in women who carry the BRCA1/2 gene mutations is published in CMAJ.
