The primary outcome was spontaneous PTB before 34 weeks' gestation (WG).Results: Of 68 participants, 39 were treated with the traditional method (group 1) and 29 with the new insertion technique (group 2). The rate of spontaneous PTB before 34 WG was significantly lower in group 2 (p=0.020).

Data was collected from medical records and individual patient followups. Descriptive data was collected on patient demographics, amniocentesis indications, and the test results. The other outcomes analyzed were the procedure-related complications and pregnancy outcomes.Results: The mean gestational age at time of the procedure was 254/7 (241/7-331/7).

A comprehensive evaluation of clinical and laboratory indicators was conducted, employing correlation, regression, logistic analyses to determine risk factors.Results: There was a strong inverse correlation between carbon dioxide levels and haematocrit (-0.76), and a direct correlation between blood pH and partial pressure of oxygen (0.73). COVID-19 was associated with increased risks of preterm labor (OR=1.82), stillbirth (OR=2.11), pre-eclampsia (OR=1.46), and foetal distress. Multivariate analysis revealed a 200 g reduction in neonatal birth weight and higher risks of hospitalisation (OR=1.8), postpartum hemorrhage (OR=2.3), and preterm delivery (OR=2.5). Comorbid conditions such as cardiovascular abnormalities, diabetes, obesity, thrombophilias exacerbated the risks of complications, including pre-eclampsia, neonatal respiratory distress syndrome, venous thromboembolism.Conclusions: COVID-19 infection increases the likelihood of pregnancy complications and adverse outcomes, especially in women with comorbidities.

Although CPR is used for monitoring growth-restricted fetuses, its role in guiding labor induction decisions for AGA pregnancies at term remains unclear.Methods: A retrospective cohort study was conducted using data from 491 singleton pregnancies with intended vaginal deliveries between 2015 and 2021. CPR was assessed at the actual estimated date of delivery (40+0 weeks' gestation). Adverse pregnancy outcome (APO) as the primary endpoint was defined by admission to neonatal intensive care unit (NICU), umbilical cord blood pH<7.1, 5-min APGAR<7 or interventions-due-to-fetal-distress during labor (IDFD=vaginal-operative delivery or emergency caesarean section).Results: APO nearly doubled (adjOR 1.7; CI 1.007-2.905) when CPR was below our calculated cut-off of 1.269 (18.4 vs. 32.3 %, p=0.002) and NICU admissions (4.8 vs. 11.1 %, p=0.020) and IDFD (12.5 vs. 21.2 %, p=0.027) significantly increased. The positive predictive value for the presence of APO using our cut-off was 32.4 %, and the negative predictive value 81.6 %.Conclusions: Our data confirm a predictive value of a reduced CPR at term with impaired perinatal outcome. The cut-off of CPR<1.269 may guide decision-making regarding induction of labor.

Cases of hypoplastic left heart syndrome diagnosed in the prenatal period between 2014 and 2023 were extracted from electronic medical records. Demographic data, echocardiographic features, results of genetic testing, pregnancy outcomes, and postnatal outcomes were analyzed.Results: Eighty-three prenatally diagnosed fetal HLHS cases were analyzed. Overall, survival during the study period was 26.5 %, and survival among live births was 35.4 %. Survival analysis has shown that the majority of deaths occurred during the neonatal period. Out of 62 live births, 47 had Norwood procedures, six had balloon procedures and three had hybrid procedures. Eleven out of 47 who had the Norwood procedures went on to have a Glenn operation, and only three had full Fontan palliation. The presence of additional extra-cardiac anomaly, need for extracorporeal membrane oxygenation (ECMO), bidirectional flow at pulmonary veins on color Doppler, and low birth weight are associated with survival and early neonatal death. Tricuspid regurgitation, restrictive foramen ovale, and fetal growth restriction (FGR) are not associated with survival. HLHS evolved from critical aortic stenosis has better survival rates.Conclusions: Extra-cardiac anomaly, need for ECMO, bidirectional flow at pulmonary veins, and low birth weight were negatively associated with survival and early neonatal death.
