Maternal super obesity is increasing and is associated with an increased risk of pregnancy complications-a call for concern.

OBJECTIVE: This study aimed to assess the relationship of increased body mass index (BMI) with pregnancy complications. STUDY DESIGN: We obtained data for a retrospective cohort of singleton live births using an electronic birth certificate database from 2010 to 2022. Institutional review board exemption was obtained. BMI was assessed as a continuous variable and a categorical variable with groups of BMI 18.5-29.9 kg/m2, 40-49.9 kg/m2, and ≥50 kg/m2 compared to patients with BMI 30-39.9 kg/m2. Primary outcomes were pregnancy and maternal outcomes. Secondary outcomes were neonatal outcomes. ANOVA and χ2 were used to compare continuous and categorical variables respectively, and logistic regression was used to obtain adjusted odds ratios for primary and secondary outcomes. RESULTS: There were 223,837 patients with singleton live births with mean BMI 27.86 kg/m2. 54,385 (24.3%) had BMI 30-39.9 kg/m2, 13,299 (5.9%) had BMI 40-49.9 kg/m2, and 1,958 (0.87%) had BMI ≥50 kg/m2. Patients with BMI > 50 kg/m2 have a higher likelihood of APGAR scores <7 (aOR 1.38, 95% CI 1.05-1.83), and NICU admission or transfer out of facility (aOR 1.17, 95% CI 1.02-1.34). In the nulliparous subgroup analysis, For patients with BMI >50 kg/m2, there was a higher odds of preterm birth <37 weeks (aOR 1.57, 95% CI 1.23-2.00) and preterm birth <34 weeks (aOR 1.51 95% CI 1.00-2.30. There is also an increased odds of cesarean section in both of these BMI groups (aOR 1.68 95% CI 1.57-1.79 and aOR 2.30 95% CI 1.94-2.72). CONCLUSION: BMI ≥ 50 kg/m2 was significantly associated with increased pregnancy complications.

Patients with BMI > 50 kg/m² have a higher likelihood of having pregestational diabetes, gestational diabetes, chronic hypertension, gestational hypertension, and preterm birth < 37 weeks.Increasing obesity in Central New York is leading to worsened pregnancy outcomes.

Pulse Pressure as a Hemodynamic Parameter in Preeclampsia with Severe Features Accompanied by Fetal Growth Restriction.

Background: Modern management of preeclampsia can be optimized by tailoring the targeted treatment of hypertension to an individual's hemodynamic profile. Growing evidence suggests different phenotypes of preeclampsia, including those with a hyperdynamic profile and those complicated by uteroplacental insufficiency. Fetal growth restriction (FGR) is believed to be a result of uteroplacental insufficiency. There is a paucity of research examining the characteristics of patients with severe preeclampsia who do and who do not develop FGR. We aimed to elucidate which hemodynamic parameters differed between these two groups. Methods: All patients admitted to a single referral center with severe preeclampsia were identified. Patients were included if they had a live birth at 23 weeks of gestation or higher. Multiple gestations and pregnancies complicated by fetal congenital anomalies and/or HELLP syndrome were excluded. FGR was defined as a sonographic estimation of fetal weight (EFW) < 10th percentile or abdominal circumference (AC) < 10th percentile. Results: There were 76% significantly lower odds of overall pulse pressure upon admission for those with severe preeclampsia comorbid with FGR (aOR = 0.24, 95% CI = 0.07-0.83). Advanced gestational age on admission was associated with lower odds of severely abnormal labs and severely elevated diastolic blood pressure in preeclampsia also complicated by FGR. Conclusions: Subtypes of preeclampsia with and without FGR may be hemodynamically evaluated by assessing pulse pressure on admission.

Comparison between high transverse and low transverse Pfannenstiel skin incisions during cesarean delivery for morbidly obese patients.

OBJECTIVE: This study aimed to evaluate if placement of transverse cesarean skin incision above or below the overhanging pannus is associated with wound morbidity in morbidly obese patients. STUDY DESIGN: We identified a cohort of patients with body mass index (BMI) ≥40 kg/m2 undergoing cesarean delivery at a single center from 2017-2020 with complete postpartum records. Data was abstracted after institutional review board exemption, and patients were grouped by low transverse or high transverse skin incision. The primary outcome was a composite of wound infection, fascial dehiscence, incisional hernia, therapeutic wound vacuum, and reoperation. Secondary outcomes included the individual components of the composite, blood transfusion, operative time, and immediate neonatal outcome. T test and χ2 were used for continuous and categorical comparisons. Logistic regression was used to compute adjusted odds ratios for categorical outcomes and linear regression to compare operative times adjusting for factors associated with wound complications and surgical duration respectively. RESULTS: 328 patients met inclusion criteria: 65 with high transverse (infraumbilical and supraumbilical) and 263 with low transverse (Pfannenstiel) incision. 11% of patients had wound morbidity; high transverse incision was associated with 3.64-fold increased odds of composite wound morbidity (23.1% vs 8%, aOR 3.64, 95% CI 1.52-8.70) and 5.73-fold increased odds of wound infection (13.8% vs. 4.9%, aOR 5.73, 95% CI 1.83-17.96). Time from skin incision to delivery was 1.87 min longer (11.09 vs 14.98 min, ß = 1.87, 95% CI 0.17-4.61). There was no significant difference in neonatal outcomes, non-low transverse hysterotomy, or total operative time. CONCLUSION: High transverse skin incision for cesarean delivery was strongly associated with increased wound morbidity in morbidly obese patients.

Outcomes after cesarean delivery were assessed for 328 patients with morbid obesity.High transverse skin incision for cesarean delivery was associated with increased wound morbidity and wound infection.Prospective studies will be needed to determine if skin incision placement causes wound morbidity.

Cross-Sectional Survey of High-Risk Pregnant Women's Opinions on COVID-19 Vaccination.

Background: Pregnant women are at increased risk of severe disease with coronavirus disease 2019 (COVID-19). Despite strong recommendations from American College of Obstetricians and Gynecologists and Society for Maternal Fetal Medicine for vaccination, COVID-19 vaccination hesitancy persists. With this study, we aim to evaluate opinions about the COVID-19 vaccine in a cohort of high-risk pregnant patients. Materials and Methods: Institutional review board approval was obtained. Patients attending a regional Maternal-Fetal Medicine clinic in central New York were surveyed about the COVID-19 vaccine using a standardized questionnaire. Demographic, obstetrical, and medical information was abstracted using medical records. The vaccinated and unvaccinated groups were evaluated using chi-square tests and a Bayesian model. Results: Among the 157 participants, 38.2% are vaccinated. There were no significant differences in race/ethnicity, living situation, marital status, employment status, insurance type, pregravid body mass index, history of recreational drug use, number of living children, or gestational age at the time of survey. Patients with less formal education are less likely to be vaccinated. There was no difference between influenza and tetanus diphtheria pertussis vaccination rates with COVID-19 vaccination rates. Unvaccinated patients cite lack of data in pregnancy (66%) as their primary concern. Most patients prefer to learn about vaccines via conversation with their doctor (46.7% for vaccinated and 59.8% for unvaccinated). Conclusions: The vaccination rate is low in our population. A provider-initiated conversation about COVID-19 vaccination included with routine prenatal care could increase the vaccination rate.
