Screen for "silent" heart attacksOne in 11 patients who undergo major non-cardiac surgery will suffer post-op heart attacks, 10% of them fatal, within 30 days of surgery, according to Daniel Sessler, MD, chair of the department of outcomes research at the Cleveland Clinic. Dr. Sessler says most (80%) who suffer post-op heart attacks will show no clinical symptoms or signs. "Blood concentration of troponin is the best indicator," he explains, although most surgical patients don't undergo the inexpensive, quick and accurate screening. He presented his findings last week at the Annual Congress of the Association of Anaesthetists of Great Britain and Ireland. Hospital MRSA declining2011 saw 30,800 fewer cases of MRSA in the U.S. than in 2005, according to a CDC report in JAMA Internal Medicine. Hospital-onset cases fell 54% during those 6 years, but healthcare-associated, community-onset cases decreased only 28% and community-associated cases fell only 5%. "Infections with onset in the community or outpatient setting remain problematic and represent the majority of invasive MRSA infections," researchers write. Statins linked to cataractsMedications taken to reduce cholesterol may increase the risk of cataracts, according to a study published in JAMA Ophthalmology, though the authors note that previous studies have yielded different results. The most recent study, carried out at the San Antonio Military Medical Center, compared 6,972 statin users and non-users and found an increased risk that held up when other factors were accounted for.
