MedicalResearch.com: What is the background for this study? What are the main findings?

Response: In recent years, use of stimulant medications in adults, including women of reproductive age, has increased substantially.

However, data regarding the safety of stimulant medications in early pregnancy are sparse and conflicting.  For example, two recent cohort studies failed to detect an association between use of methylphenidate in early pregnancy and overall or cardiac malformations, while another found an 81% increased risk of cardiac malformations, although the estimate was imprecise.

Given the rapidly increasing use of stimulant medications during pregnancy and among women of reproductive age who may become pregnant inadvertently, there is an urgent need to better understand their safety.

MedicalResearch.com: What is the background for this study?

Response: Congenital heart defects (CHD) are the most common forms of congenital disorders and a relevant cause of perinatal morbidity and mortality involving about 0.8% of pregnancies. IVF pregnancies are very common nowadays with increasing rates in the developed countries worldwide. There is no consensus in current practice guidelines whether IVF/ICSI conception represents an indication for performing a fetal echocardiogram according to different eminent scientific societies due to differences in the estimations of the risk for CHD in the available literature.

MedicalResearch.com: What is the background for this study?

Response: Congenital heart disease (CHD) is the leading birth defect in the United States and often results in an array of long-term neurological deficits including motor, cognitive and behavioral abnormalities. It has become increasingly clear that children with CHD often have underdeveloped brains. In many cases of complex CHD, blood flow to the brain is both reduced and less oxygenated, which has been associated with developmental abnormalities and delay. The cellular mechanisms underlying the impact of CHD on brain development remain largely unknown. We developed a preclinical chronic hypoxia model to define these mechanisms.
