In a 5-year, randomized, placebo-controlled clinical study, researchers found that giving nitroglycerin to mothers who had entered premature labor led to significant improvement in their baby’s health. The results of the study are reported in the January issue of the American Journal of Obstetrics & Gynecology.
In previous studies of drugs to suppress labor contractions to allow the fetus more time to develop in utero, some drugs were able to delay delivery, but none improved the baby’s health outcome. This study is the first to show that the baby benefited from the therapy, especially those who are born very prematurely (at 24 to 28 weeks). Using a composite measure of the newborn’s health including perinatal death, markers of brain damage and serious lung and bowel complications, mothers treated with nitroglycerin had significantly healthier babies.
Graeme N. Smith, MD, PhD, states, “Our team is very excited about these findings. It is estimated that it costs the Canadian health system almost $2 billion a year to take care of premature babies and their medical complications. Given the immeasurable societal and family costs associated with preterm birth and having a sick baby or child, treatment with nitroglycerin may result in major cost saving and longer-term health benefits for these babies.”
In an accompanying editorial, Associate Editor Jay D. Iams, MD, writes about the study, “Their work is notable not only for their interesting results but also for the quality of the study design, execution, and report.” He continues, “Perhaps most importantly, the authors chose neonatal morbidity, a ‘health outcome,’ as the primary endpoint instead of a surrogate such as days gained or percent of births before 32 or 35 weeks of gestation.”

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
