Genome-editing method repairs mutations that cause beta-thalassemia
A genome-editing technique has been used to correct mutations that cause beta-thalassemia in human cell lines. Researchers transformed skin cells from a patient into induced pluripotent stem cells and then fixed the mutations before prompting the cells to mature into hematopoietic progenitors and erythroblasts. More work is needed before cells are developed that could be used in transplants. The findings were reported in the journal Genome Research. The Scientist online (8/5)

Implanted neurons derived from skin cells function normally, researchers find
Luxembourg Centre for Systems Biomedicine researchers have successfully grafted induced neuronal stem cells into the brains of mice, raising hopes for development of treatments for neurodegenerative conditions. Six months after implantation, synapses had formed to connect the neurons, which were reprogrammed from the mice's own skin cells, with the rest of the brain, and the implanted cells functioned normally. The study appeared in the journal Stem Cell Reports. Wired.co.uk (U.K.) (8/5)

Obese patients have better chances of surviving sepsis, study suggests
Obesity is associated with improved mortality among sepsis patients, according to a study in the journal Critical Care Medicine. Based on data involving 1,404 Medicare patients, obese sepsis patients had lower mortality rates, and their functional outcomes were comparable with those of normal-weight patients with sepsis. Extra weight could change how the body responds to disease, and understanding how may lead to improved sepsis care, researchers suggested. BeckersHospitalReview.com (8/5)

New blood imaging and analysis tool detects malaria
A mobile health tool has been designed to provide quick analysis of blood samples for the diagnosis of diseases such as malaria. Athelas, the winner of a YC Hacks competition, uses a small lens attached to a smartphone camera to magnify images of blood samples. The images are analyzed using accompanying software that provides malarial cell counts. MedGadget.com (8/5)

App to detect anemia earns top prize at Microsoft tech challenge
A mobile health application that can be used to detect anemia in patients has nabbed the top prize at the 2014 Microsoft Imagine Cup challenge. Eyenaemia, designed by medical students Jarrel Seah and Jennifer Tang, allows users to take pictures of their eyes, have the images analyzed and find out their risk of having the condition.

Defense Department supports trials of in-flight plasma
The Prehospital Air Medical Plasma, or "PAMPer," trial is evaluating the use of plasma to treat trauma patients during flights rather than after they reach a hospital. The Pentagon-supported study at six U.S. medical centers will assess the intervention's effects on survival, clotting measurements on arrival and transfusion requirements.
