Adverse Pregnancy

Background and Objectives: Mild gestational diabetes (GDM) refers to the gestational hyperglycemia, which does not fulfill the diagnostic criteria for GDM. The results of studies on adverse pregnancy outcomes among women with mild GDM are controversial. Therefore, the aim of this systematic review and meta-analysis was to investigate the impact of mild GDM on the risk of adverse maternal and neonatal outcomes.Methods: A thorough literature search was performed to retrieve articles that investigated adverse maternal and neonatal outcomes in women with mild GDM in comparison with non-GDM counterparts. All populations were classified to three groups based on their diagnostic criteria for mild GDM. Heterogeneous and non-heterogeneous results were analyzed using the fixed/random effects models. Publication bias was assessed using the Harbord test. DerSimonian and Laird, and inverse variance methods were used to calculate the pooled relative risk of events. Subgroup analysis was performed based on mild GDM diagnostic criteria. Quality and risk of bias assessment were performed using standard questionnaires.Results: Seventeen studies involving 11,623 pregnant women with mild GDM and 53,057 non-GDM counterparts contributed to the meta-analysis. For adverse maternal outcomes, the results of meta-analysis showed that the women with mild GDM had a significantly higher risk of cesarean section (pooled RR: 1.3, 95% CI 1.2–1.5), pregnancy-induced hypertension (pooled RR: 1.4, 95% CI 1.1–1.7), preeclampsia (pooled RR: 1.3, 95% CI 1.1–1.5) and shoulder dystocia (pooled RR: 2.7, 95% CI 1.5–5.1) in comparison with the non-GDM population. For adverse neonatal outcomes, the pooled relative risk of macrosomia (pooled RR = 0.4, 95% CI: 1.1–1.7), large for gestational age (pooled RR = 1.7, 95% CI: 1.3–2.3), hypoglycemia (pooled RR = 1.6, 95% CI: 1.1–2.3), hyperbilirubinemia (pooled RR = 1.1, 95% CI: 1–1.3), 5 min Apgar <7 (pooled RR = 1.6, 95% CI: 1.1–2.4), admission to the neonatal intensive care unit (pooled RR = 1.5, 95% CI: 1.1–2.1), respiratory distress syndrome (pooled RR = 3.2, 95% CI: 1.8–5.5), and preterm birth (pooled RR = 1.4, 95% CI: 1.1–1.7) was significantly increased in the mild GDM women as compared with the non-GDM population. However, the adverse events of small for gestational age and neonatal death were not significantly different between the groups. Analysis of composite maternal and neonatal outcomes revealed that the risk of those adverse outcomes in the women with mild GDM in all classifications were significantly higher than the non-GDM population. Also, the meta-regression showed that the magnitude of those increased risks in both composite maternal and neonatal outcomes was similar.Conclusion: The risks of sever adverse neonatal outcomes including small for gestational age and neonatal mortality are not increased with mild GDM. However, the increased risks of most adverse maternal and neonatal outcomes are observed. The risks have similar magnitudes for all mild GDM diagnostic classifications.

Abstract Study question Does an elevated SDF (>15%) increase the odds of adverse maternal and neonatal outcomes in autologous oocyte IVF-ICSI cycles from unselected couples? Summary answer No adverse effects of high SDF on obstetric and neonatal outcomes have been found in couples with sperm fragmentation undergoing IVF-ICSI cycles with own eggs. What is known already Sperm chromatin integrity assessment has been implemented as an additional tool in the clinical evaluation of sperm quality in infertile patients undergoing an assisted reproduction treatment. All of the published reports to date appraise its effect on clinical outcomes, and how it impacts embryo quality and the pregnancy chances after IVF and ICSI cycles. Sperm DNA integrity has also been hypothesized to affect offspring health but not many studies have reported in humans if an elevated SDF raises the risks of obstetric, delivery and neonatal outcomes. Study design, size, duration Multicentric retrospective cohort study of all IVF-ICSI cycles using autologous oocytes between January 2000-March 2019 at Spain IVIRMA clinics of couples with a SDF test on their ejaculated semen. The sperm fragmentation index was measured in all men with TUNEL assay. The database included 228 couples which had a delivery with at least a newborn. Subjects were divided into two study groups according to their level of SDF: ≤15% (low SDF) or > 15% (high SDF). Participants/materials, setting, methods Patients with missed information on maternal and neonatal outcomes were not counted for the analysis. The obstetric outcomes were gestational age, gestational diabetes, preeclampsia (hypertension with proteinuria after 20 weeks of gestation) and type of delivery. Neonatal outcomes were sex, birth weight, length, head circumference, Apgar score at 1, 5, 10 minutes, and neonatal intensive care unit (NICU) admission. Student’s t-test and Fisher’s test were used for statistical analysis. A p-value<0.05 was considered statistically significant. Main results and the role of chance Maternal age mean was 37.4 years (95%CI 36.9-38.0) in ≤ 15%SDF group and 37.2 years (95%CI 36.1-38.4) in > 15%SDF group (p = 0.8). Similar gestational age was found, 41.8 weeks (95%CI 41.3-42.2) in ≤ 15%SDF and 41.3 weeks (95%CI 40.4-42.3) in > 15%SDF. Gestational diabetes incidence was higher in > 15%SDF compared to ≤ 15%SDF group (3.5% versus 1.7% (OR = 2.0 (95%CI 0.03-39.8), p = 0.5). Equally, the incidence of preeclampsia was 3.6% in patients with high SDF versus 1.7% in couples with low SDF, OR = 2.1 (95%CI 0.03-41.3), p = 0.5. Type of delivery frequency was in the ≤15%SDF group 61.9% vaginal and 38.1% cesarean, while in the >15%SDF group 62.1% vaginal and 37.9% cesarean (OR = 1.0 (95%CI 0.4-2.6), p = 1.0). The overall proportion of singleton pregnancies was 87.2% (95%CI 82.4-91.2) and twins 12.8% (95%CI 8.8-17.6). There were no statistically differences between groups in the rate of delivery of twins and in the sex ratio of the newborns. When comparing the newborns of ≤ 15%SDF with >15%SDF group, the average of weight was 3011.7g (95%CI 2912.2-3111.2) versus 2986.4g (95%CI 2753.1-3219.7), of length was 49.2cm (95%CI 48.3-50.0) versus 49.5cm (95%CI 49.2-49.9), of head circumference was 34.9cm (95%CI 34.6-35.2) versus 34.3cm (95%CI 33.4-35.2). No statistically differences were observed for Apgar punctuation and for NICU admission. Limitations, reasons for caution Due to the retrospective nature of the study we have missing data from the lack of follow-up of many patients after the confirmation of the ongoing pregnancy. Although pregnancies of couples with elevated SDF have a higher incidence of gestational diabetes and preeclampsia, the sample size evaluated is a limitation. Wider implications of the findings This is one of the first reports to evaluate the relationship between paternal DNA damage and obstetric risks and neonatal health in couples with high SDF who underwent IVF-ICSI in our centers. Despite SDF did not jeopardize the maternal and neonatal outcomes, more studies are needed to confirm this conclusion. Trial registration number NA

Vegetarian Diets

Abstract Background Vegetarian diets are becoming increasingly popular in the USA. Limited research has examined the health consequences of vegetarian diets during pregnancy. We comprehensively examined associations of vegetarianism during pregnancy with maternal and neonatal outcomes. Methods We used data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development’s Fetal Growth Studies–Singletons, a prospective multi-site cohort of 1948 low-risk pregnant women of four races/ethnicities (White, Black, Hispanic, Asian/Pacific Islander) in the USA (2009–2013). Vegetarianism was self-reported and also defined based on dietary patterns measured using a self-administered first-trimester food-frequency questionnaire (full [lacto-ovo and vegan], pesco-, semi- and non-vegetarians). Neonatal outcomes included birthweight and neonatal anthropometric measures, small for gestational age, small for gestational age with neonatal morbidity and preterm delivery. Maternal outcomes included gestational weight gain, gestational diabetes, hypertensive disorders of pregnancy and gestational anaemia. Results Ninety-nine (6.2%) women self-reported being vegetarian. The diet-based definition identified 32 (2.0%) full vegetarians, 7 (0.6%) pesco-vegetarians and 301 (17.6%) semi-vegetarians. Neonates of diet-based full vegetarians had higher odds of being small for gestational age [adjusted odds ratio (ORadj) = 2.51, 95% confidence interval: 1.01, 6.21], but not of being small for gestational age with a postnatal morbidity. Full vegetarians had marginally increased the odds of inadequate second-trimester gestational weight gain (ORadj = 2.24, 95% confidence interval: 0.95, 5.27). Conclusion Vegetarian diets during pregnancy were associated with constitutionally smaller neonatal size, potentially via the mothers’ reduced gestational weight gain. Notably, vegetarianism was not associated with small-for-gestational-age-related morbidities or other adverse maternal outcomes.
