Clopidogrel pretreatment for PCI does not reduce risk of overall mortality

Among patients scheduled for a percutaneous coronary intervention (PCI; procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries), pretreatment with the antiplatelet agent clopidogrel was not associated with a lower risk of overall mortality but was associated with a significantly lower risk of major coronary events, according to a review and meta-analysis of previous studies published in the December 19 issue of JAMA.

Research Roundup: Medicare Advantage Plan beneficiaries may get more appropriate use of services; CHIP participation grows; College students' flu vaccination rates weak

Analysis Of Medicare Advantage HMOs Compared With Traditional Medicare Shows Lower Use of Many Services During 2003-09 – Researchers compared the utilization rates of Medicare Advantage health maintenance organizations (HMOs) with those of traditional Medicare beneficiaries, 2003-09, "to ascertain whether the HMO enrollees demonstrated different levels of use of services, which can be a hallmark of more integrated care."

Pay for performance may have reduced UK mortality rates

The introduction in 2008 of a US-based “pay-for-performance” scheme into National Health Service hospitals in the northwest of the UK resulted in a significant decrease in mortality rates, particularly for pneumonia, study findings show.

Intramyocardial injection of organ-derived stem cells after AMI improves left ventricle function

A study published in the current issue of Cell Transplantation, now freely available on-line, has found that when mesenchymal cells derived from skeletal muscle (SM-MSCs) or adipose tissue (ADSCs) were injected into the heart muscle (myocardium) of separate groups of laboratory rats that had suffered a myocardial infarction, rats in both groups experienced significantly improved left ventricle function and smaller infarct size after cell therapy.
