AIM: Elevated human chorionic gonadotropin (HCG) and alpha fetoprotein (AFP) have been linked to placental dysfunction and associated morbidities. We aimed to compare the induction of labor with expectant management at term in those pregnancies for the prevention of neonatal and maternal morbidities. METHODS: Women with second trimester HCG ≥ 2 and/or AFP ≥ 2 multiples of the median, without additional maternal or fetal complications, from their 38th gestational week were offered the choice of labor induction or expectant management...

It was reported that high blood cholesterol levels increased the susceptibility to mitochondrial dysfunction. This study hypothesized that the gestational hypercholesterolemia (HC) could induce the mitochondrial dysfunction in term human placenta. The eligible pregnant women were recruited from Xuanwu Hospital in Beijing during their first prenatal visit (before their 10th week of pregnancy). In total, 19 pregnant women whose serum total cholesterol levels were higher than 7.25 mm at third trimester (measured at 36-38 weeks) were selected as gestational HC...

In mouse models used to study parturition or pre-clinical therapeutic testing, measurement of uterine contractions is limited to either ex vivo isometric tension or operative IUP. The goal of this study was to: 1) develop a method for transcervical insertion of a pressure catheter to measure in vivo intrauterine contractile pressure during mouse pregnancy, 2) determine whether this method can be utilized numerous times in a single mouse pregnancy without affecting the timing of delivery or fetal outcome, and 3) compare the in vivo contractile activity between mouse models of term and preterm labor (PTL)...

BACKGROUND: Neonatal nonoliguric hyperkalemia (NOHK) is a metabolic abnormality that occurs in extremely premature neonates at approximately 24 h after birth and is mainly due to the immature functioning of the sodium (Na + )/potassium (K + ) pump. Magnesium sulfate is frequently used in obstetrical practice to prevent preterm labor and to treat preeclampsia; this medication can also cause hypermagnesemia and hyperkalemia by a mechanism that is different from that of NOHK. Herein, we report the first case of very early-onset neonatal hyperkalemia induced by maternal hypermagnesemia...

Sustainable Development Goal (SDG) 5 calls on nations to promote gender equality and to empower women and girls. SDG5 also recognizes the value of women's economic empowerment, entailing equal rights to economic resources and full participation at all levels in economic decisions. Also according to SDG5, eliminating harmful practices-such as child marriage before age 18-is a prerequisite for women's economic empowerment. Using national data for 4,129 married women 15-43 years who took part in the Egypt Labor Market Panel Survey (ELMPS 1998-2012), we performed autoregressive, cross-lagged panel analyses to assess whether women's first marriage in adulthood (at 18 years or older, as reported in 2006), was positively associated with their long-term post-marital economic empowerment, measured as their engagement in market work and latent family economic agency in 2012...

The non-canonical NF-κB signaling (RelB/p52) pathway drives pro-labor genes in the human placenta, including corticotropin-releasing hormone (CRH) and cyclooxygenase-2 (COX-2), making this a potential therapeutic target to delay onset of labor. Here we sought to identify small molecule compounds from a pre-existing chemical library of orally active drugs that can inhibit this NF-κB signaling, and in turn, human placental CRH and COX-2 production. We used a cell-based assay coupled with a dual-luciferase reporter system to perform an in vitro screening of a small molecule library of 1,120 compounds for inhibition of the non-canonical NF-κB pathway...

Diagnoses of "complications of pregnancy, childbirth, and the puerperium" include both morbid complications and indications for routine care of pregnant women. During 2012-2016, a total of 55,601 U.S. service members with live births (n=63,879) had 657,060 medical encounters with primary diagnoses of "pregnancy complications." The most frequent diagnoses were "other" specified conditions complicating pregnancy, childbirth, or the puerperium. Numbers of medical encounters with a primary (first-listed) diagnosis of any pregnancy-related complication or indication for care decreased marginally each year between 2012 (n=178,703) and 2016 (n=146,282)...

Increased susceptibility to influenza virus infection during pregnancy has been attributed to immunological changes occurring before and during gestation in order to "tolerate" the developing fetus. These systemic changes are most often characterized by a suppression of cell-mediated immunity and elevation of humoral immune responses referred to as the Th1-Th2 shift. However, the underlying mechanisms which increase pregnant mothers' risk following influenza virus infection have not been fully elucidated...

Oxidative stress affects the contractile behavior of smooth muscle resulting in complications during labor. Toxicants such as lindane and ferric chloride (FeCl3 )/adenosine diphosphate (ADP) cause oxidative stress and have previously been shown to inhibit smooth muscle contraction. In this study we examined the effects of the oxygen species scavengers, ascorbic acid and N-acetylcysteine on lindane and FeCl3 /ADP's inhibition of spontaneous myometrial contractions in rat and human myometrium. Lindane and FeCl3 /ADP gave rise to concentration-dependent reductions in rat (EC50 11...

BACKGROUND: Rates of cesarean delivery are continuously increasing in industrialized countries, with repeated cesarean accounting for about a third of all cesareans. Women who have undergone a first cesarean are facing a difficult choice for their next pregnancy, i.e.: (1) to plan for a second cesarean delivery, associated with higher risk of maternal complications than vaginal delivery; or (b) to have a trial of labor (TOL) with the aim to achieve a vaginal birth after cesarean (VBAC) and to accept a significant, but rare, risk of uterine rupture and its related maternal and neonatal complications...

INTRODUCTION: Gestational Diabetes Mellitus (GDM), diabetes diagnosed during pregnancy is associated with maternal (caesarean delivery, hypoglycaemia, hyperbilirubinaemia, shoulder dystocia, pre-term delivery and birth trauma) and fetal (Hyperbilirubinaemia in offspring, Neonatal hypoglycaemia, Macrosomia) complications. Despite, insulin being the standard treatment for GDM cases, there is no existing comprehensive consensus update on use of insulin in Indian patients with GDM. OBJECTIVE: To provide simple and easily implementable guidelines to healthcare physicians on use of insulin in GDM...
