Flu vaccine protects pregnant women against pertussis

05.04.2018 Health Problems

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

05.04.2018 Health Problems

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

05.04.2018 Health Problems

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 […]

Is Alzheimer’s caused by disruptions to the brain’s energy supply?

05.04.2018 Health Problems

It is well known that Alzheimer’s disease, the most common form of dementia, involves the accumulation of sticky proteins (plaques and tangles) in the brain. But we still don’t know what the root cause of the disease is. Given that someone, somewhere in the world, is diagnosed with dementia every three seconds, there is an urgent race to discover the […]

How to fight side effects of hormone therapy for prostate cancer

04.04.2018 Health Problems

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 […]

For women with kidney cancer, belly fat matters

04.04.2018 Health Problems

Belly fat affects the odds of women surviving kidney cancer but not men, according to a new study by researchers at Washington University School of Medicine in St. Louis. Half of female kidney cancer patients with substantial abdominal fat at the time of diagnosis died within 3 1/2 years, while more than half of women with little belly fat were […]

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

04.04.2018 Health Problems

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

03.04.2018 Health Problems

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

03.04.2018 Health Problems

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 […]

Key heart risks decline for older Americans

03.04.2018 Health Problems

(HealthDay)—Older Americans dramatically reduced their risks for heart attack and stroke over a recent 20-year period, a new analysis finds. The likely reason: greater use of drugs to control cholesterol and blood pressure, as well as a decline in smoking, according to researchers from the University of Southern California. The benefits were seen in both sexes, which suggests women are […]
