Purpose: This study aimed to compare the effects of early cord clamping (ECC), delayed cord clamping (DCC), and umbilical cord milking (MC) on maternal and neonatal outcomes in elective cesarean births. Methods: We analyzed 204 women with uncomplicated at-term singleton pregnancies, who underwent cesarean birth under regional anesthesia between March and July 2021. The women were randomized into three groups: DCC (clamped 60 s postpartum), ECC (clamped within 15 s postpartum), or MC (clamped after milking five times) group. The neonatal and maternal outcomes of the groups were evaluated. Results: The duration of the operation was significantly lower (P < 0.001) in the MC group at 50 min (ECC, 60 min; DCC, 60 min), while intraoperative bleeding was significantly higher (P < 0.001) in the ECC group at 500 mL (DCC, 300 mL; MC, 225 mL). The rates of anemia and polycythemia significantly differed (P = 0.049) between the three groups. DCC and MC did not negatively affect maternal and neonatal outcomes compared with ECC. Conclusion: DCC and MC are superior to ECC in terms of short-term maternal and neonatal outcomes in cases of elective cesarean birth under regional anesthesia. [ABSTRACT FROM AUTHOR]

Background: The literature provides limited evidence of cord blood leptin levels in gestational diabetes mellitus (GDM), with contradictory and inconsistent results with respect to their possible implications for maternal, perinatal, and future complications. Methods: MEDLINE/PubMed, Embase, Scopus, and Web of Science databases were searched in order to investigate the state of evidence on the association of leptin profile in cord blood during perinatal complications in GDM. We critically assessed the risk of bias using the Newcastle-Ottawa scale. Meta-analyses were performed, and heterogeneity and publication bias were analyzed. Results: sixteen primary-level studies were included, recruiting 573 GDM and 1118 control pregnant women. Cord blood leptin levels were significantly higher in GDM participants compared to controls (standardized mean difference [SMD] = 0.59, 95% confidence intervals (CI) = 0.37 to 0.80, p < 0.001). All subgroups also maintained significant differences stratified by continents (Asia: SMD = 0.91, 95% CI = 0.45 to 1.37, p < 0.001; Europe: SMD = 0.38, 95% CI = 0.20 to 0.56, p < 0.001), analysis technique (ELISA: SMD = 0.70, 95% CI = 0.44 to 0.97, p < 0.001; RIA: SMD = 0.30, 95% CI = 0.11 to 0.49, p = 0.002), and sample source (plasma: SMD = 0.71, 95% CI = 0.33 to 1.09, p < 0.001; serum: SMD = 0.55, 95% CI = 0.34 to 0.77, p < 0.001). Conclusion: Cord blood leptin levels were significantly higher in GDM compared to controls. Further research is needed to clarify its role as a predictive biomarker of subsequent metabolic diseases in mothers with GDM and offspring. [ABSTRACT FROM AUTHOR]

Aims: The study purposed to evaluate the success rate of cervical ripening using dinoprostone controlled‐release vaginal insert and reveal some factors relating to successful cervical ripening. Methods: This cross‐sectional study was conducted at Tu Du Hospital in Vietnam from December 2021 to August 2022. The study enrolled 200 pregnant women with gestational age ≥37 weeks diagnosed with oligohydramnios. These candidates underwent dinoprostone cervical ripening (DCR) according to the local protocol. The Bishop score ≥7 after 24 h was determined for the successful cervical ripening (SCR). Results: In total, the success rate of DCR achieved at 57.5% and the cesarean delivery rate was 46.5%. None of the severe side‐effects and complications was present. Using multivariable logistic regression, the study found that the body mass index ≥25 kg/m2 and oxytocin infusion drip related to SCR with adjusted odds ratio (aOR): 3.67 (95% confidence intervals [CI]: 1.78–7.57) and aOR: 4.68 (95% CI: 1.84–11.93), p < 0.001. Using the Kaplan–Meier curve, the present study revealed a significant difference between Bishop <3 and ≥3 following the duration time of cervical ripening, with hazard ratio: 1.38 (95% CI: 1.19–1.59), p < 0.001. The time duration of cervical ripening was not significantly different following amniotic fluid index from 3 to 5 cm. Conclusions: Cervical ripening using a dinoprostone vaginal insert is a potentially acceptable method in term pregnancy accompanying with oligohydramnios. The probability of SCR can be predicted on a careful assessment of relative factors by obstetricians. Further studies are required to strengthen these findings. [ABSTRACT FROM AUTHOR]

Gestational diabetes mellitus (GDM) represents a stage of subclinical inflammation and a risk factor for subsequent future type 2 diabetes and cardiovascular disease development. Leptin has been related with vascular and metabolic changes in GDM with heterogeneous and contradictory results with respect to their possible involvement in maternal, perinatal, and future complications. Our objective is to evaluate current evidence on the role of leptin in maternal and perinatal complications in women with GDM. PubMed, Embase, Web of Science, and Scopus databases were searched. We evaluated the studies' quality using the Newcastle-Ottawa scale. Meta-analyses were conducted, and heterogeneity and publication bias were examined. Thirty-nine relevant studies were finally included, recruiting 2255 GDM and 3846 control pregnant women. Leptin levels were significantly higher in GDM participants than in controls (SMD = 0.57, 95%CI = 0.19 to 0.94; p < 0.001). Subgroup meta-analysis did not evidence significant differences in leptin in the different trimesters of pregnancy. Meta-regression showed a positive significant relationship for HOMA in the GDM group (p = 0.05). According to these results, it seems that high levels of leptin can be used as predictive markers in GDM. [ABSTRACT FROM AUTHOR]

A pre-gestational thyroid reserve of iodine is crucial to guarantee the increased demand for thyroid hormone production of early pregnancy. An iodine intake ≥150 µg/day is currently recommended. The objective of this study was to assess average pre-gestational food-based iodine consumption in pregnant women at their first prenatal visit (p = 0.026), a lower miscarriage rate, and a decrease in the composite of materno-fetal adverse events (0.81; 0.67–0.98). Reaching the recommended iodine pre-pregnancy intake with foods could benefit the progression of pregnancy.

Endothelial dysfunction has been considered as a key etiological factor contributed to the development of vascular disease in diabetes mellitus. Serum level of endothelial cell adhesion molecules (AMs) were reported to be increased in GDM and pregnant women with normal glucose tolerance when compared with nonpregnant women. The literature provides limited evidence of endothelial dysfunction in GDM with heterogeneous and contradictory results respect to their possible involvement in maternal, perinatal and future complications. Our objective is to evaluate current evidence on the role of AMs in maternal and perinatal complications in women with GDM. PubMed, Embase, Web of Science, and Scopus databases were searched. We evaluated the studies' quality using the Newcastle-Ottawa scale. Meta-analyses were conducted, and heterogeneity and publication bias were examined. Nineteen relevant studies were finally included, recruiting 765 GDM and 2368 control pregnant women. AMs levels were generally higher in GDM participants showing statistical significance maternal ICAM-1 levels (SMD = 0.58, 95% CI = 0.25 to 0.91; p = 0.001). Our meta-analysis did not detect significant differences in subgroups or in meta-regression analyses. Future studies are needed to establish the potential role of these biomarkers in GDM and its complications. [ABSTRACT FROM AUTHOR]

A pre-gestational thyroid reserve of iodine is crucial to guarantee the increased demand for thyroid hormone production of early pregnancy. An iodine intake ≥150 µg/day is currently recommended. The objective of this study was to assess average pre-gestational food-based iodine consumption in pregnant women at their first prenatal visit (<12 gestational weeks), and its association with adverse materno-fetal events (history of miscarriages, early fetal losses, Gestational Diabetes, prematurity, caesarean sections, and new-borns large/small for gestational age). Between 2015–2017, 2523 normoglycemic women out of 3026 eligible had data in the modified Diabetes Nutrition and Complication Trial (DNCT) questionnaire permitting assessment of pre-gestational food-based iodine consumption, and were included in this study. Daily food-based iodine intake was 123 ± 48 µg, with 1922 (76.1%) not reaching 150 µg/day. Attaining this amount was associated with consuming 8 weekly servings of vegetables (3.84; 3.16–4.65), 1 of shellfish (8.72; 6.96–10.93) and/or 2 daily dairy products (6.43; 5.27–7.86). Women who reached a pre-gestational intake ≥150 µg had lower rates of hypothyroxinemia (104 (17.3%)/384 (21.4%); p = 0.026), a lower miscarriage rate, and a decrease in the composite of materno-fetal adverse events (0.81; 0.67–0.98). Reaching the recommended iodine pre-pregnancy intake with foods could benefit the progression of pregnancy. [ABSTRACT FROM AUTHOR]
