WHAT:
A team of researchers funded by the National Institutes of Health has developed a new ultrasound technique to monitor the placenta for impaired fetal blood flow early in pregnancy. The technique, which uses conventional ultrasound equipment, relies on subtle differences in the pulsation of fetal blood through the arteries at the fetal and placental ends of the umbilical cord, potentially enabling physicians to identify placental abnormalities that impair fetal blood flow and, if necessary, deliver the fetus early. Like current ultrasound techniques, the new technique can also detect impaired flow of maternal blood through the placenta.
The study was conducted by John G. Sled, Ph.D., of The Hospital for Sick Children in Toronto, and colleagues. It appears in

A hot topic symposia session during the Pediatric Academic Societies (PAS) 2021 Virtual Meeting will address the persistent controversies and questions in preterm infant nutrition.
After six years of interdisciplinary expert discussion and critical evidence review, the 2014 vision to develop evidence-informed guidance for the nutritional care of preterm infants has come to fruition. The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and the Academy of Nutrition and Dietetics (AND) initiated this multiphase process involving expert physician, dietitian, and pharmacology scientists.

Researchers are now able to wirelessly record the directly measured brain activity of patients living with Parkinson s disease and to then use that information to adjust the stimulation delivered by an implanted device. Direct recording of deep and surface brain activity offers a unique look into the underlying causes of many brain disorders; however, technological challenges up to this point have limited direct human brain recordings to relatively short periods of time in controlled clinical settings.
NIH BRAIN Initiative-funded study opens the door to correlating deep brain activity and behavior.

Being exposed to higher air pollution levels for a month could speed up cognitive decline in older men, a study has suggested.
Researchers found people performed poorer in recall and reaction time tests if air pollution levels increased in the 28 days before they were quizzed.
But men taking commonly prescribed anti-inflammatory drugs such as aspirin were less affected, scientists discovered.
The study, by Peking University in China, looked at a cohort of nearly 1,000 men with an average age of 70 who lived in Boston in the US.
Cognitive function was assessed using a series of tests over time to determine their memory, attention and learning.
