In a population-based cohort study, 65,085 mother-child pairs from the Danish National Birth Cohort were followed up in real time from early pregnancy into childhood. "Maternal use of inhaled glucocorticoids for asthma during pregnancy was not related to an increased risk of most diseases in childhood, except for endocrine and metabolic disorders, as compared to the risk in asthmatic mothers without glucocorticoid inhalation during pregnancy," said first author Marion Tegethoff, PhD, associate faculty member in clinical psychology and psychiatry at the University of Basel, Switzerland. "Our data are mostly reassuring and support the use of inhaled glucocorticoids during pregnancy."
The findings were published online ahead of print publication in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
Of 65,085 mother-child pairs with live singleton pregnancies, 61,002 had no asthma during pregnancy (93.7%) and 4083 (6.3%) had asthma during pregnancy. Median age at end of follow-up was 6.1 years (range: 3.6 to 8.9 years). In statistical analyses adjusted for baseline predictors of child health, use (versus no use) of inhaled glucocorticoids was associated with a significantly increased risk for the first diagnosis of endocrine and metabolic disorders (hazard ratio [HR], 1.84; 95% confidence interval [CI], 1.13-2.99), but not of diseases in any other category. Results were similar when analyses were restricted to mother-child pairs exposed only to budesonide, the inhaled glucocorticoid used by the majority of women (79.9%) in the study.
"This is the first comprehensive study of potential effects of glucocorticoid inhalation during pregnancy on the health of offspring, covering a wide spectrum of pediatric diseases," said last author Gunther Meinlschmidt, PhD, associate faculty member in clinical psychology and epidemiology at the University of Basel, Switzerland. "While our results support the use of these widely used asthma treatments during pregnancy, their effect on endocrine and metabolic disturbances during childhood merits further study."
There were some limitations to the study, including a lack of data on daily inhalation doses, use of self-report of maternal asthma and the study's focus on glucocorticoid inhalation rather than other active ingredients or glucocorticoids administered by other routes.
"Our data have both clinical and public health implications," the authors concluded, "given that asthma is common in pregnant women and inhaled glucocorticoids are the recommended treatment."

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
