Research Team Finds Key Target Of Aging Regulator
Researchers at The Wistar Institute have defined a key target of an evolutionarily conserved protein that regulates the process of aging. The study, published June 11 in Nature, provides fundamental knowledge about key mechanisms of aging that could point toward new anti-aging strategies and cancer therapies.

Maryland ICU Patients Connected To Remote Critical Care Staff, Improving Qualtiy And Safety
Maryland intensive care patients will now be connected by voice, video and data lines to specialized physicians and nurses at a tertiary care referral center 130 miles away. A year after announcing six, independent Maryland hospitals, with a $3 million grant from CareFirst BlueCross BlueShield, were joining together to provide state-of-the-art critical care to their patients, the first hospital, Calvert Memorial Hospital in Prince Frederick, Md., is fully online with the sophisticated care system.

'Artificial Gravity' Can Prevent Muscle Loss In Space
When the Apollo 11 crew got back from the moon, 40 years ago this week, they showed no ill effects from seven days spent in weightlessness. But as American astronauts and Soviet cosmonauts began conducting longer-duration space flights, scientists noticed a disturbing trend: the longer humans stay in zero gravity, the more muscle they lose. Space travelers exposed to weightlessness for a year or more - such as those on a mission to Mars, for example - could wind up crippled on their return to Earth, unable to walk or even sit up.

Cost-Effective Measures Could Stop Child Pneumonia Deaths

Implementing measures to improve nutrition, indoor air pollution, immunization coverage and the management of pneumonia cases could be cost-effective and significantly reduce child mortality from pneumonia, according to a study led by the Johns Hopkins Bloomberg School of Public Health. Researchers found that these strategies combined could reduce total child mortality by 17 percent and could reduce pneumonia deaths by more than 90 percent. Pneumonia is a leading cause of death of infants in many developing countries, resulting in 2.2 million deaths each year. The study is published in the June 2009 issue of the Bulletin of the World Health Organization. The study, conducted in collaboration with the World Health Organization (WHO) and other public health schools, assessed economic aspects of existing child interventions and identified the most efficient pneumonia control strategies. Programs to promote better community-based treatment of pneumonia, promotion of exclusive breastfeeding, zinc supplementation and vaccination for Hib and S. pneumoniae were found to be the most cost-effective interventions. The burning of solid fuels like wood, for cooking and heating, was found to contribute at least 20 percent to the burden of childhood pneumonia. "The interventions we examined already exist, but are not fully implemented in the developing world. In addition, implementation of these interventions do not require a great deal of new infrastructure to carry out," said Louis Niessen, MD, PhD, lead author of the study and associate professor in the Bloomberg School"s Department of International Health. "Fully funding and implementing these interventions could bring us a big step closer towards reaching the U.N. Millennium Development Goals." "The next step is to assess how donors and countries currently deliver these interventions and want to progress in the coming years," said Majid Ezzati, PhD, co-investigator of the study and associate professor at the Harvard School of Public Health. "Comparative impact assessment of child pneumonia interventions" was written by Louis Niessen, Anne ten Hove, Henk Hilderink, Martin Weber, Kim Mulholland and Majid Ezzati. The research was supported by grants from the Netherlands Environmental Assessment Agency, the WHO and the United Nations Children"s Fund.
