Glucagon-like peptide-1 receptor agonist use in pregnancy: a review.

Glucagon-like peptide-1 receptor agonists are peptide analogues that are used to treat type 2 diabetes mellitus and obesity. The first medication in this class, exenatide, was approved in 2005, and these medications, specifically semaglutide, have become more popular in recent years due to their pronounced effects on glycemic control, weight reduction, and cardiovascular health. Due to successful weight loss from these medications, many women previously diagnosed with oligomenorrhea and unable to conceive have experienced unplanned pregnancies while taking the medications. However, there are currently little data for clinicians to use in counseling patients in cases of accidental periconceptional exposure. In some studies examining small animals exposed to glucagon-like peptide-1 receptor agonists in pregnancy, there has been evidence of adverse outcomes in the offspring, including decreased fetal growth, skeletal and visceral anomalies, and embryonic death. Although there are no prospective studies in humans, case reports, cohort studies, and population-based studies have not shown a pattern of congenital anomalies in infants. A recent large, observational, population-based cohort study examined 938 pregnancies affected by type 2 diabetes mellitus and compared outcomes from periconceptional exposure to glucagon-like peptide-1 receptor agonists and insulin. The authors concluded there was not a significantly increased risk of major congenital malformations in patients taking glucagon-like peptide-1 receptor agonists, although there was no information on maternal glycemic control or diabetic fetopathy. As diabetic embryopathy is directly related to the degree of maternal hyperglycemia and not the diagnosis of diabetes itself, it is not possible to make this conclusion without this information. Furthermore, there is little evidence available regarding fetal growth restriction, embryonic or fetal death, or other potential complications. At this time, patients should be counseled there is not enough evidence to predict any adverse effects, or the lack thereof, of periconceptional exposure of glucagon-like peptide-1 receptor agonists during pregnancy. We recommend that all patients use contraception to prevent unintended pregnancy while taking glucagon-like peptide-1 receptor agonists.

The impact of trimester of COVID-19 infection on pregnancy outcomes after recovery.

OBJECTIVES: Many physiological adaptations occur during pregnancy. It is not currently known how timing of COVID-19 infection impacts pregnancy. We hypothesize that maternal and neonatal outcomes are different if COVID-19 infection occurs in different trimesters of pregnancy. METHODS: This retrospective cohort study was conducted from 3/2020 to 6/2022. Pregnant patients with a positive COVID-19 infection more than 10 days before delivery (COVID-recovered) were identified and grouped by trimester of infection. Demographics and maternal, obstetric, and neonatal outcomes were analyzed. ANOVA, Wilcoxon rank-sum test, Pearson's chi-squared test, and Fisher's exact test were used to compare continuous and categorical data. RESULTS: A total of 298 COVID-recovered pregnant patients were identified. Of those, 48 (16 %) were infected in the 1st trimester, 123 (41 %) in the 2nd, and 127 (43 %) in the 3rd. There were no significant demographic differences between the study groups. Vaccination status was similar. Hospital admission rate and the need for oxygen therapy while infected were significantly higher in patients with 2nd or 3rd trimester infection (18 % & 20 % vs. 2 % and 13 % & 14 % vs. 0 %, respectively). Rates of preterm birth (PTB) and extreme PTB were higher in the 1st trimester infection group. Infants born to mothers infected in the 2nd trimester had more neonatal sepsis workups (22 % vs. 12 % & 7 %). Other outcomes were similar between groups. CONCLUSIONS: First trimester COVID-recovered patients were more likely to have a preterm birth despite having lower rates of hospital admission and oxygen supplementation while infected than patients who recovered from a 2nd or 3rd trimester infection.

The Optimal Cesarean Skin Incision in Patients with Super Obesity.

OBJECTIVE: This study aimed to evaluate if supraumbilical midline vertical incision performed in patients with a hanging pannus (umbilicus at the level of the pubic bone) is a reasonable alternative to the Pfannenstiel in patients with body mass index (BMI) ≥ 50 kg/m2 undergoing cesarean delivery. STUDY DESIGN: Retrospective cohort study in patients with BMI ≥ 50 kg/m2 undergoing cesarean delivery at a single center from 2016 to 2020. Study groups were Pfannenstiel's versus supraumbilical vertical skin incision. If patients had a hanging pannus (umbilicus at the level of the pubic bone), vertical incisions were performed. Otherwise, Pfannenstiel's incision was performed. Decision for the incision was made prospectively. Primary outcome was a composite of need for blood transfusion, presence of immediate surgical complications, and presence of delayed surgical complications. Secondary outcomes included the individual components of the primary outcome, the median surgical blood loss, total operative time, time from skin incision to delivery of neonate, hysterotomy type, and neonatal outcomes. MedCalc 19.5.1 was used for analysis. RESULTS: A total of 103 patients with BMI ≥50 kg/m2 were included. Of those, 68 (66%) had Pfannenstiel's and 35 (34%) had supraumbilical vertical incisions. There was no statistically significant difference in the incidence of the primary outcome (12 vs. 11%, p = 0.96). There was neither significant difference in immediate or delayed postoperative complications nor in neonatal outcomes. However, patients in the vertical midline incision group were more likely to have a classical hysterotomy (52%) compared with the Pfannenstiel group (6%; p < 0.05), increased overall median surgical blood loss (1,000 vs. 835 mL, p < 0.05), and increased total surgical time by a median of 30 minutes (p < 0.05). CONCLUSION: In patients with super obesity and hanging pannus, performing a supraumbilical vertical midline incision offers a reasonable alternative to Pfannenstiel's incision, but patients should be counseled about the increased risk for classical hysterotomy and implications in future pregnancies. KEY POINTS: · Patients with BMI >50 kg/m2 were allocated to different incision types based on subcutaneous fat distribution pattern. If umbilicus was at level of pubic bone, supraumbilical vertical skin incision was made. · There were no significant differences between Pfannenstiel's and supraumbilical vertical incisions in terms of the composite outcome and immediate or delayed postoperative complications and neonatal outcomes.. · In patients with a hanging pannus, performing a supraumbilical vertical midline incision offers a reasonable alternative to Pfannenstiel's incision, but patients should be counseled about the increased risk for classical hysterotomy and subsequent implications in future pregnancies..

Fetal Alcohol Exposure: The Common Toll.

Alcohol has always been present in human life, and currently it is estimated that 50% of women of childbearing age consume alcohol. It has become increasingly clear over the last years that alcohol exposure during fetal development can have detrimental effects on various organ systems, and these effects are exerted by alcohol through multiple means, including effects on free radical formation, cellular apoptosis, as well as gene expression. Fetal alcohol exposure can lead to a spectrum of short term as well as long-term problems, with Fetal Alcohol Syndrome being on the more severe end of that spectrum. This syndrome is morbid, yet preventable, and is characterized by midfacial hypoplasia, thin upper lip, widely spaced small eyes, long smooth philtrum and inner epicanthal folds. Other findings include growth restriction as well as various neurodevelopmental abnormalities. This article is the first comprehensive review combining the molecular as well as the gross physiological and anatomical effects of alcohol exposure during pregnancy on various organ systems in the body. Our knowledge of these various mechanisms is crucial for our understanding of how alcohol exposure during fetal development can lead to its detrimental effects.
