Study examines how social support affects mental health after a natural disaster

A new Journal of Traumatic Stress study found that social support may have helped alleviate depressive symptoms for displaced and nondisplaced residents who survived Hurricane Katrina. Also, social support appeared to only moderate the effects of posttraumatic stress disorder (PTSD) symptoms for nondisplaced residents, indicating that displaced individuals may require more formal supports for reducing PTSD symptoms following a natural […]

Flu vaccine protects pregnant women against pertussis

Research by Wits scientists shows that pregnant women vaccinated against influenza also have less pertussis infection. Pertussis, also known as whooping cough, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. Wits researchers at the MRC Respiratory and Meningeal Pathogens Research Unit (RMPRU) published a paper in the New England Journal of Medicine, which shows that pregnant […]

Researchers advise long-term monitoring of infants infected with Zika after birth

A collaborative research team led by Ann Chahroudi, MD, PhD, of Emory University is recommending long-term clinical monitoring for infants infected with Zika virus early after birth. The recommendation is based on the team’s research results showing for the first time that postnatal Zika virus infection of rhesus macaque infants results in persistent abnormalities in brain structure and function as […]

Researchers test stem cell-based retinal implant for common cause of vision loss

Physicians and researchers at the USC Roski Eye Institute have collaborated with other California institutions to show that a first-in-kind stem cell-based retinal implant is feasible for use in people with advanced dry age-related macular degeneration. The results of their phase I/IIa study, which was funded in part by the California Institute for Regenerative Medicine, were published today in Science […]

How to fight side effects of hormone therapy for prostate cancer

Men on hormone therapy for prostate cancer may benefit significantly from hitting the gym with fellow patients and choosing more veggies and fewer cheeseburgers, a new study suggests. Androgen deprivation therapy is a powerful tool against prostate cancer, and more and more men are opting for the treatment as a growing array of hormone-based therapies become available. But it comes […]

Three-month-old infants can learn abstract relations before language comprehension

Three-month-old babies cannot understand words and are just learning to roll over, yet they are already capable of learning abstract relations. In a new study, Northwestern University researchers show for the first time that 3-month-old infants can learn same and different relations. “Recent theories have suggested that humans’ fluency in relational learning—our ability to make comparisons between objects, events or […]

Flare-responsive hydrogel developed to treat arthritis

Arthritis flares – the unpredictable and often sudden worsening of arthritis symptoms—can be debilitating. These episodes can make the management of inflammatory arthritis, which includes rheumatoid arthritis and psoriatic arthritis, challenging for patients and physicians. But investigators at Brigham and Women’s Hospital have found that flares may also represent an important opportunity for improving treatment options for patients. In experiments […]

Mathematical modeling offers new way to understand variable responses to targeted therapy

Cancer therapies that target a specific protein have improved outcomes for patients. However, many patients eventually develop resistance to these targeted therapies and their cancer comes back. It is believed that differences among tumor cells, or heterogeneity, may contribute to this drug resistance. Moffitt Cancer Center researchers are using a unique approach by combining typical cell culture studies with mathematical […]
