- 13.11.2008 The Future of Primary Care: Perspectives in the New England Journal of Medicine
You may be interested in several perspectives on the state of primary care in the U.S. that appear in the current New England Journal of Medicine.
Six experts approach the topic from various angles, including the need to refocus on the physician-patient relationship and a call for reform of payment systems. Several of the commentators also took part in a roundtable discussion, which was videotaped and is available on the journal's website. + zobacz więcej - 13.11.2008 News from AHA 2008

Findings from a Lancet meta-analysis raise questions about the use of beta-blockers in intermediate- or high-risk patients undergoing noncardiac surgery, as current guidelines recommend.
Researchers pooled data from 33 randomized trials comparing beta-blockers with control therapy among some 12,300 surgical patients. + zobacz więcej - 12.11.2008 New Google Tool Can Help Americans Track the Flu
Google.org, the company's philanthropic unit, has launched a Web tool that could spot regional flu outbreaks in the U.S. as early as a week before the CDC reports them, according to the New York Times.
Google Flu Trends analyzes searches on influenza (e.g., "flu symptoms") to estimate flu activity in a given area, and then uses the data to create maps of where the illness may be spreading. Google believes the site may allow people to take precautions if influenza is in their region, the Times reports. + zobacz więcej - 12.11.2008 Angiotensin-Receptor Blocker of No Benefit in Patients with Heart Failure, Preserved Systolic Function
The angiotensin-receptor blocker irbesartan does not improve outcomes in patients with heart failure and preserved left-ventricular ejection fractions, according to an industry-supported study published online by the New England Journal of Medicine.
Some 4000 patients aged 60 or older with heart failure and ejection fractions of at least 45% were randomized to receive irbesartan (titrated up to 300 mg daily) or placebo. During roughly 4 years' follow-up, overall mortality and hospitalization for cardiovascular causes did not differ significantly between the groups. + zobacz więcej - 12.11.2008 Manufacturer Recalls More Drugs Because of Potentially Oversized Tablets

Rosuvastatin reduces cardiovascular events among adults who have elevated high-sensitivity C-reactive protein without high cholesterol, according to an industry-funded study released online by the New England Journal of Medicine.
Nearly 18,000 adults without hyperlipidemia (LDL below 130 mg/dL) but with elevated CRP (2 mg/L or higher) were randomized to rosuvastatin or placebo. The trial was stopped after roughly 2 years, when the rate of the primary endpoint — first major cardiovascular events (e.g., MI, stroke) — was lower with rosuvastatin than with placebo (0.77 vs. 1.36 events per 100 person-years). + zobacz więcej - 10.11.2008 Low-Dose Aspirin Does Not Appear to Reduce Atherosclerotic Events in Type 2 Diabetes
Low-dose aspirin does not appear to reduce atherosclerotic events in adults with type 2 diabetes, according to a JAMA report released online.
Researchers in Japan randomized some 2500 adults with diabetes without atherosclerosis to receive open-label, low-dose aspirin (81 or 100 mg daily) or no aspirin. During roughly 4 years' follow-up, the incidence of any atherosclerotic event did not differ significantly between the aspirin and control groups (13.6 and 17.0 events per 1000 person-years, respectively). + zobacz więcej - 10.11.2008 MP3 Player Headphones May Interfere with Pacemakers
Patients may ask about a widely reported study suggesting that the magnets in MP3 player headphones can interfere with pacemakers and implantable defibrillators.
According to the study, presented Sunday at the American Heart Association meeting, the problem occurs only if earbuds or other headsets are placed within about an inch of the implanted devices. In one-quarter of the 60 patients studied, this caused inappropriate pacing or inhibited the defibrillators. + zobacz więcej
