To describe the fetal regional myocardial strain rate in the membranous ventricular septum across gestation and to determine their predictive value for a complete membranous ventricular septum (without defect) after delivery. In 1150 fetuses, the peak systolic strain rate (SRs), peak early diastolic strain rate (SRe) and peak late diastolic strain rate (SRa) in the membranous ventricular septum were measured at four time points across gestation (18-20, 24-26, 30-32 and 36-38 weeks). The integrity of the interventricular septum was examined at 12 weeks' postnatal age...

Acute chest syndrome is a complication of sickle cell disease and represents the highest cause of mortality in those afflicted with the disorder. Pregnancy represents an increased risk for complications of sickle cell disease in both the mother and fetus. We present a case of a 20-year-old patient with known sickle cell disease who was at 25-week gestation and developed acute chest syndrome refractory to conventional therapies and requiring emergency cesarean section. Following delivery, the patient developed acute respiratory distress syndrome (ARDS) requiring extracorporeal membrane oxygenation (ECMO)...

The purpose of this paper is to review scientific evidence concerning pathogens that could potentially be transmitted via bovine semen. As a result of a careful analysis of the characteristics of infections that may cause transmission of disease through semen, effective control procedures can be identified that provide minimal constraint to the introduction of new bulls into herds for natural breeding and importation of valuable novel genetics through artificial insemination. The potential for transmission through bovine semen and corresponding effective control procedures are described for bovine herpesvirus 1, bovine viral diarrhea virus, bovine leukemia virus, lumpy skin disease virus, bluetongue virus, foot-and-mouth disease virus, and Schmallenberg virus...

The increasing availability of developmental data on humans and great apes has become essential for furthering our understanding of human evolution. Although postnatal ontogeny is relatively well documented, our knowledge about variation of developmental patterns during the prenatal period among primate species remains lacking. There are various limitations to studying fetuses, but investigating the fetal period, directly or indirectly, has the potential to answer questions that are otherwise difficult to tackle with postnatal examination...

The specialty of fetal surgery or fetal intervention is one of the most exciting emerging fields of modern medicine. It is made possible by decades of major developments in antenatal imaging, obstetric anaesthesia, fetal medicine, paediatric surgery and of course by the bold and novel practitioners willing to take new steps to advance the field. Beginning in the 1970s it has now reached a stage of maturity where there are several established in-utero procedures and countless clinical trials and studies to develop more...

REVIEW
R Townsend, A Khalil
Twin pregnancies are more likely to be affected by fetal growth restriction (FGR), preterm birth and perinatal loss. The management of fetal growth restriction in multiple pregnancy, particularly where only one fetus is affected is complicated by the need to consider the interests of both twins. Selective growth restriction in monochorionic (MC) twins is a pathophysiological process distinct from FGR in dichorionic (DC) pregnancies and management demands an understanding of the monochorionic placental structure and interdependent fetal circulations...

This study aimed to evaluate whether the addition of resveratrol to vitrification/thawing medium improves the cryotolerance of preantral follicles enclosed in bovine ovarian fragments. Ovarian fragments were obtained from bovine fetuses and distributed to the following groups: fresh ovarian fragments (control), vitrified (VIT), and vitrified with resveratrol (VIT + RESV). Overall, the mean percentage of normal follicles was greater (P < 0.05) in the VIT + RESV compared to the VIT group. Moreover, the probability of finding normal follicles was 2...

OBJECTIVE: Twin pregnancy is associated with 2-3 fold increased risk of stillbirth compared to singletons. Despite the fact that the growth pattern has been shown to differ in twins compared to singletons, it is controversial whether twin-specific growth charts should be routinely used. A major goal of prenatal ultrasound is to identify fetuses suffering from growth restriction at risk of stillbirth. The main aim of this study was to compare the performance of chorionicity-specific twin charts with singleton charts, both customized and non-customized, in the antenatal prediction of small-for-gestational age (SGA) stillborn and liveborn fetuses...

During pregnancy and lactation, the maternal body undergoes many changes in the regulation of appetite, body weight and glucose homeostasis to deal with the metabolic demands of the growing fetus and subsequent demands of providing milk for offspring. The aim of the current study was to investigate the consequences of one reproductive cycle of pregnancy and lactation on the long-term regulation of energy homeostasis. After weaning of pups, reproductively experienced (RE) mice maintained a higher body weight compared to age-matched control mice...
