Women following bariatric surgery have lower risk for gestational diabetes mellitus and fetal macrosomia as compared with obese parturients. Nevertheless, bariatric surgery is a risk factor for anemia.

A total of 410 measurements were included. Of them 255 were normal and 155 abnormal. The CC length/estimated fetal weight (EFW) ratio had the strongest linear association with GA (R = 0.929). Applying charts using this ratio to the normal group, significantly increased the percent of CC length measurements defined as normal from 84.7 to 94.5% (p < .001). Conversely, applying these charts to the abnormal group nonsignificantly decreased the number of measurement defined as normal from 89 to 83.2% (p = .137) Conclusions: The CC length/EFW ratio is strongly and linearly associated with GA. Using this personalized ratio may improve the diagnostic accuracy of CC evaluation by adjusting the CC length to the fetus natural proportions.

ESS is a safe and efficient procedure for diagnosing and treating immunosuppressed pediatric patients with acute rhinosinusitis. Early detection and aggressive medical and surgical treatment, with control of underlying risk factors, are crucial to improve outcome.

Objective To study maternal and intrapartum factors associated with adverse neonatal outcome in deliveries complicated by meconium‐stained amniotic fluid (MSAF). Methods A retrospective cohort study of all women with singleton gestations undergoing trial of labor with MSAF during 2011–2020. Deliveries with adverse neonatal outcome were compared with deliveries without. Results Overall, 11 329 were included; 376 (3.3%) neonates were diagnosed with adverse neonatal outcomes. Multivariable regression analysis underlined the following factors as independently associated with composite adverse neonatal outcome: pregestational diabetes (odds ratio [OR] 3.21, 95% confidence interval [CI] 1.09–9.43, P = 0.031), polyhydramnios (OR 2.14, 95% CI 1.33–3.44, P = 0.002), fever (OR 2.52, 95% CI 1.67–3.80, P < 0.001), and amnioinfusion (OR 1.73, 95% CI 1.24–2.2438, P = 0.003). When 0, 1, 2, and 3 of the independent risk factors identified were present, the rates of adverse neonatal outcome were 2.9%, 5.5%, 10.0%, and 100%, respectively. Conclusion The current study's results suggest that special attention should be payed to deliveries complicated by MSAF and with any of the following factors—polyhydramnios, intrapartum fever, amnioinfusion, and pregestational diabetes.
