Two-year urgent heart transplant (UT) free survival in high vs normal WC groups was 77.9% vs 64.3% (P = .025) and in high vs normal BMI was 89.8% vs 58.2% (P < .001). After multivariable adjustment, normal WC compared with high WC was associated with higher all-cause mortality (risk ratio [RR] 2.76, 95% confidence interval [CI] 1.34-5.71)

and higher risk of death/UT (RR 2.14, 95% CI 1.25-3.68). The best outcomes were seen in those with both high WC and high BMI.

Conclusions: High WC, an alternative anthropometric index of obesity more specific to abdominal adiposity, high BMI, and the combination of high WC/high BMI were each associated with improved outcomes in this advanced HF cohort, lending further support for an obesity paradox in HF. The role of body composition in HF survival should be a focus of future investigation. (J Cardiac Nec-1s manufacturer Fail 2011;17:374-380)”
“The ferromagnetism induced by the intrinsic point defects in wurtzite zinc oxide is studied by using ab initio calculation based on density functional theory. The calculations show that both oxygen interstitial and zinc vacancy may induce 17-AAG datasheet ferromagnetism into this material. The calculations also show that zinc oxide with oxygen interstitial may be a ferromagnetic semiconductor.

Based on the simplified electronic configuration of the defect molecules, we explain the total magnetic moment, electronic structure, and ferromagnetism. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3062822]“
“The worldwide elderly population is expected to grow by an additional 694 million people by 2025. By that time, there will be approximately two billion elderly people in the world, most of whom (80%) will be living in developing countries. Based on recent estimates, this population will number over 40 million in 2030 in Brazil and a consequent increase in governmental spending for this population can be expected. Since highly active antiretroviral

therapy became available in the mid-1990s, the life expectancy of people living with HIV has increased significantly. Approximately 12 million life years were added to the PD0332991 solubility dmso world between 1996 and 2008 as a consequence of wider access to highly active antiretroviral therapy. In Brazil, the incidence of AIDS among the population aged >= 50 years doubled between 1996 and 2006. The development of antiretroviral therapy has allowed individuals diagnosed at a younger age to live longer, which partially explains the aging tendency associated with the HIV/AIDS epidemic. It is estimated that by 2015, subjects aged >= 50 years will represent 50% of the people living with HIV undergoing clinical treatment.
