Abstract
Babies born growth restricted are at an increased risk of both poor short-and long-term outcomes. Current interventions to improve fetal growth are ineffective and do not lower the lifetime risk of poor health status. Maternal resveratrol (RSV) treatment increases uterine artery blood flow, fetal oxygenation, and fetal weight. However, studies suggest that diets high in polyphenols such as RSV may impair fetal hemodynamics. We aimed to characterize the effect of RSV on fetal hemodynamics to further assess its safety as an intervention strategy. Pregnant ewes underwent magnetic resonance imaging (MRI) scans to measure blood flow and oxygenation within the fetal circulation using phase contrast-MRI and T2 oximetry. Blood flow and oxygenation measures were performed in a basal state and then repeated while the fetus was exposed to RSV. Fetal blood pressure and heart rate were not different between states. RSV did not impact fetal oxygen delivery (DO2 ) or consumption (VO2 ). Blood flow and oxygen delivery throughout the major vessels of the fetal circulation were not different between basal and RSV states. As such, acute exposure of the fetus to RSV does not directly impact fetal hemodynamics. This strengthens the rationale for the use of RSV as an intervention strategy against fetal growth restriction.

Abstract
Abstract
Objectives
The aim of this article was to present a case of premature fetal closure of the ductus arteriosus (DA) of unknown cause.
Case presentation
A 32-year-old pregnant woman came for the regular prenatal visit at 36 + 1 weeks of gestation (WG) at which oligohydramnios and premature closure of DA were revealed. Use of non-steroidal anti-inflammatory drugs was excluded by the history, although the patient had the symptoms of common cold 2 weeks before the check-up taking more than 1,000 mL of strong chamomile tea daily till the day before the prenatal visit. The patient was hospitalized at 36 + 1 weeks of gestation due to premature closure of DA and oligohydramnios (amniotic fluid index = 4.5/3), which was the indication to deliver the baby by cesarean section at 36 + 6 WG (birth weight was 2,830 g, birth length 49 cm and head circumference 34 cm, Apgar score at 1 and 5 min were 9/9). Postnatal course was uneventful, and postnatal echocardiography at 12 h of life revealed functionally closed DA and mild dysfunction of the right ventricle, which completely resolved after 7 days. The mother and the baby were discharged home healthy, and were doing well 3 months after delivery.
Conclusions
Although the cause of premature closure of DA in most of the cases will remain undetected, thorough history sometimes with unexpected events should be taken under the consideration as possible causative factor for premature DA closure, as was drinking of high quantities of chamomile tea in our case.
