Short-Term Pulmonary, Immunologic, Or Coagulation Status Unaffected By Duration Of RBC Storage published
Tue, 24 Jan 2012 00:00:00 PST
There is no difference in early measures of pulmonary function, immunologic status or coagulation status after fresh versus standard issue single-unit red blood cell (RBC) transfusion, according to a new study from the Mayo Clinic. "Longer duration of RBC storage is thought to increase the risk of transfusion-related pulmonary complications," said Daryl J...
Extracorporeal Membrane Oxygenation As A Bridge To Lung Transplantation published
Tue, 24 Jan 2012 00:00:00 PST
Extracorporeal membrane oxygenation (ECMO) support in awake, non-intubated patients may be an effective strategy for bridging patients to lung transplantation, according to a new study from Germany. "As waiting times for donor organs continue to increase, so does the need for bridging strategies for patients with end-stage lung disease awaiting transplantation," said Marius M...
First Genome-Wide Study Of High-Altitude Adaptations published
Tue, 24 Jan 2012 00:00:00 PST
Over many generations, people living in the high-altitude regions of the Andes or on the Tibetan Plateau have adapted to life in low-oxygen conditions. Living with such a distinct and powerful selective pressure has made these populations a textbook example of evolution in action, but exactly how their genes convey a survival advantage remains an open question...
