Irvine, Calif., June 21, 2021 — A large-scale meta-analysis led by University of California, Irvine researchers provides the strongest evidence yet of which blood pressure medications help slow memory loss in older adults: those that can travel out of blood vessels and directly into the brain. The findings, published in the American Heart Association journal Hypertension, will be of interest to the 91 million Americans whose blood pressure is high enough to warrant medication, as well as the doctors who treat them.
According to researchers at Johns Hopkins Medicine, the Massachusetts Institute of Technology (MIT) and Rice University in Houston, silicone breast implants with a smoother surface design have less risk of producing inflammation and other immune system reactions than those with more roughly textured coatings. Results of the experiments using mice, rabbits and samples of human breast tissue advance knowledge of how the body responds to such implants, providing new information to physicians and affirming the benefits of certain smoother surfaces, the researchers say.

A study from Washington University School of Medicine in St. Louis suggests that many, but not all, COVID-19 therapies made from combinations of two antibodies are effective against a wide range of virus variants, and that combination therapies appear to prevent the emergence of drug resistance.
Scientists studied the brain activity of school-aged children during development and found that regions that activated upon seeing limbs (hands, legs, etc.) subsequently activated upon seeing faces or words when the children grew older. The research, by scientists at Stanford University, Palo Alto, California, reveals new insights about vision development in the brain and could help inform prevention and treatment strategies for learning disorders. The study was funded by the National Eye Institute and is published in Nature Human Behaviour.
In a retrospective study believed to be one of the largest of its kind, researchers say they have successfully charted the health risks, growth patterns, and medical and surgical outcomes of 1,374 people with the most common form of dwarfism, called achondroplasia, seen over a 60-year period at four academic medical centers, including Johns Hopkins Medicine. The findings, according to the researchers, not only affirm some long-standing views and trends in the care of those with the condition, but also offer a standardized baseline, a blueprint investigators hope will serve to speed diagnosis and improve patients’ quality of life and health.
