Oxygen is the most commonly used medicine used during neonatal resuscitation in the delivery room. Oxygen therapy in delivery room should be used judiciously to avoid oxygen toxicity while delivering sufficient oxygen to prevent hypoxia. Measurement of appropriate oxygenation relies on pulse oximetry, but adequate ventilation and perfusion are equally important for oxygen delivery. In this article, we review oxygenation while transitioning from fetal to neonatal life, the importance of appropriate oxygen therapy, its measurement in the delivery room, and current recommendations for oxygen therapy and its limitations...

Prenatal diagnosis has changed perinatal medicine dramatically, allowing for additional fetal monitoring, referral and counseling, delivery planning, the option of fetal intervention, and targeted postnatal management. Teams participating in the delivery room care of infants with known anomalies should be knowledgeable about specific needs and expectations but also ready for unexpected complications. A small number of neonates will need rapid access to postnatal interventions, such as surgery, but most can be stabilized with appropriate neonatal care...

Patients with cardiovascular disease represent a significant cohort at risk for complications during pregnancy. The normal physiologic changes of pregnancy could further compromise the hemodynamics of various cardiovascular conditions, resulting in clinical deterioration and even death. The fetus of a gravida with cardiovascular disease also has an increased risk of morbidity, including an increased risk of inherited cardiac genetic disorders, fetal growth restriction, and premature delivery. These complications also increase the risk for antenatal and perinatal mortality...

Background: Self-medication which is the act of obtaining and using one or more medicines without medical supervision is a common practice among pregnant women. Unless proper caution is taken, it may result in maternal and fetal adverse outcomes. In Ethiopia, information on self-medication practice during pregnancy is scanty. Hence, this study aimed to assess self-medication practice and associated factors among pregnant women in government health centers in Addis Ababa. Methods: An institution-based mixed study design using a sequential explanatory approach was employed among 617 pregnant women and nine key informants in Addis Ababa from May 8, 2017, to June 30, 2017...

Recent advances in the differentiation and production of human pluripotent stem cell (hPSC)-derived cardiomyocytes (CMs) have stimulated development of strategies to use these cells in human cardiac regenerative therapies. A prerequisite for clinical trials and translational implementation of hPSC-derived CMs is the ability to manufacture safe and potent cells on the scale needed to replace cells lost during heart disease. Current differentiation protocols generate fetal-like CMs that exhibit proarrhythmogenic potential...

Adult stem cells represent a fundamental biological system that has fascinated scientists over the last decades, and are currently the subject of a large number of studies aimed at better defining the properties of these cells, with a prominent focus on improving their application in regenerative medicine. One of the most used adult stem cells in clinical trials are mesenchymal stem cells (MSCs), which are multipotent cells able to differentiate into mature cells of mesodermal lineages. Following the initial studies on MSCs isolated from bone marrow, similar cells were also isolated from a variety of fetal and adult human tissues...

Fetal cells in the developmental stages function with a distinct mechanism in comparison to adult tissues, which may be a useful source for regenerative medicine in postnatal medicine; however, the precise molecular mechanism remains to be elucidated fully. The present study investigated murine fetal hepatocytes, which were cultured in vitro , and the supernatants were used for the culture with murine adipose tissue-derived cells. Notably, the results indicated that fetal hepatocyte-derived culture medium elicits the induction of differentiation of adipose tissue-derived cells to bile duct cell lineages, but not to hepatocyte lineages in mice...

The prevalence of nonalcoholic fatty liver disease (NAFLD) is usually increased with age. Non-alcoholic steatohepatitis (NASH), a serious form of NAFLD, may lead to cirrhosis and end-stage liver diseases. Induced pluripotent stem cells (iPSCs) hold promising potential in personalized medicine. Although obviation of c-Myc reduces tumorigenic risk, it also largely reduced the generation of iPSCs. Recently, Poly(ADP-ribose) polymerase 1 (Parp1) has been reported to enhance cell reprogramming. In this study, we demonstrated that forced expression of Oct4/Sox2/Klf4/Parp1 (OSKP) effectively promoted iPSC generation from senescent somatic cells from 18-month-old mouse...

OBJECTIVE: This study sought to determine whether there is practice variation in the treatment and prevention of acute venous thromboembolism (VTE) in pregnant patients, potentially to prioritize future studies. BACKGROUND: The risk of VTE during pregnancy is five-fold that of the non-pregnant state. Guidance is often lacking for the treatment and prophylaxis of VTE because there are few RCTs. METHODS: The study used a cross-sectional study design using a self-administered electronic questionnaire consisting of 11 case scenarios that were sent to hematologists, maternal-fetal medicine specialists, obstetricians and gynaecologists, and internal medicine specialists across Canada...

Ventriculomegaly is defined as dilation of the fetal cerebral ventricles and is a relatively common finding on prenatal ultrasound. The purpose of this document is to review the diagnosis, evaluation, and management of mild fetal ventriculomegaly. When enlargement of the lateral ventricles (≥10 mm) is identified, a thorough evaluation should be performed, including detailed sonographic evaluation of fetal anatomy, amniocentesis for karyotype and chromosomal microarray analysis (CMA), and a workup for fetal infection...

Technological progress in medicine has provided earlier diagnosis, even in the prenatal period. We address ultrasonographic imaging of the prenatal eye and orbit. During development of these structures, multiple pathologies and diseases can arise. Orbital anomalies can be detected prenatally using ultrasound or MRI. Some of these include congenital cataracts, hypertelorism, hypotelorism, dacryocystocele, microphthalmia, anophthalmia, orbital tumors/masses, and septo-optic dysplasia. We describe characteristic ultrasound findings of these diseases...

OBJECTIVE: Pre-eclampsia (PE) remains a leading cause of maternal and fetal morbidity and mortality. A first trimester screening algorithm predicting the risk of early onset PE has been developed and validated. Early prediction coupled with initiation of aspirin at 11 to 13 weeks in women identified as high risk is effective at reducing the prevalence of early onset PE. The aim of this study is to evaluate the cost-effectiveness of this first trimester screening program coupled with early use of low-dose aspirin in women at high risk of developing early onset PE versus current practice...

Antiepileptic medications, and valproate principally, are commonly prescribed teratogens. There is significant concern that we are not doing enough to educate clinicians and potential parents about the risks of valproate in pregnancy. There is clear advice from the Medicines and Healthcare products Regulatory Agency and the International League Against Epilepsy about the risks of valproate exposure in utero Reviews and guidelines that are focused on fetal risk, however, fall short in being able to fully replicate the complexity of a real clinical decision...

BACKGROUND: Mercury (Hg) is a well-recognized environmental pollutant known by its toxicity of development and neurotoxicity, which results in adverse health outcomes. However, the mechanisms underlying the teratogenic effects of Hg are not well understood. Imprinting genes are emerging regulators for fetal development subjecting to environmental pollutants impacts. In this study, we examined the association between preconceptional Hg exposure and the alteration of DNA methylation of imprinting genes H19, Meg3, and Peg3 in human sperm DNA...
