Abstract
The global transition towards diets high in calories has contributed to 2.1 billion people becoming overweight, or obese, which damages male reproduction and harms offspring. Recently, more and more studies have shown that paternal exposure to stress closely affects the health of offspring in an intergenerational and transgenerational way. SET Domain Containing 2 (SETD2), a key epigenetic gene, is highly conserved among species, is a crucial methyltransferase for converting histone 3 lysine 36 dimethylation (H3K36me2) into histone 3 lysine 36 trimethylation (H3K36me3), and plays an important regulator in the response to stress. In this study, we compared patterns of SETD2 expression and the H3K36me3 pattern in pre-implantation embryos derived from normal or obese mice induced by high diet. The results showed that SETD2 mRNA was significantly higher in the high-fat diet (HFD) group than the control diet (CD) group at the 2-cell, 4-cell, 8-cell, and 16-cell stages, and at the morula and blastocyst stages. The relative levels of H3K36me3 in the HFD group at the 2-cell, 4-cell, 8-cell, 16-cell, morula stage, and blastocyst stage were significantly higher than in the CD group. These results indicated that dietary changes in parental generation (F0) male mice fed a HFD were traceable in SETD2/H3K36me3 in embryos, and that a paternal high-fat diet brings about adverse effects for offspring that might be related to SETD2/H3K36me3, which throws new light on the effect of paternal obesity on offspring from an epigenetic perspective.

Abstract
BACKGROUND Histologic chorioamnionitis (HCA) is most often caused by ascending bacterial infection originating from the cervicovaginal tract. OBJECTIVES To investigate whether HCA with a fetal inflammatory response (FIR) has a worse clinical outcome than HCA alone. Further, if FIR or a positive maternal microbiologic culture obtained prior to birth were related to adverse neonatal outcomes in a cohort of extremely preterm (EP) neonates. METHODS Prospective observational cohort study recruiting EP singleton pregnancies (gestational age at birth ≤28 weeks) with confirmed HCA. FIR was defined by fetal neutrophils in the chorionic vessels and/or umbilical vessels. Positive culture was defined as growth of potentially pathogenic bacteria in a sample from the cervicovaginal tract prior to birth, or if a cervicovaginal culture was lacking, a culture result from the placenta was used. Logistic regression was used to estimate odds ratios and 95% confidence intervals for the associations between FIR, a positive culture result and adverse outcomes, defined as bronchopulmonary dysplasia (BPD), brain pathology assessed by magnetic resonance imaging, retinopathy of prematurity, necrotizing enterocolitis, early-onset neonatal sepsis, and perinatal death. A composite outcome variable included one or more adverse outcomes. RESULTS We included 71 cases with HCA, of which 51 (72%) had FIR. Maternal age, rate of clinical chorioamnionitis (CCA), preterm pre-labor rupture of membranes (PPROM), the number of women receiving antenatal steroids and antibiotics, and the rate of positive maternal cultures of potentially pathogenic bacteria were all significantly higher in the HCA with FIR. Neonates in the FIR group had significantly higher levels of blood leukocytes compared to those without. FIR was associated with a longer interval from PPROM to delivery (log-rank test: p = .022). Microbiological sampling had been performed in 63 (89%) cases, of which 60 (95%) were cervicovaginal samples. No associations were found between a positive culture and adverse neonatal outcomes, in contrast to FIR, that was significantly associated to BPD and brain pathology. CONCLUSIONS In a cohort of EP pregnancies with confirmed HCA, the presence of FIR was associated with advanced maternal age, CCA, PPROM, antenatal steroids and antibiotics, and a positive maternal culture of potentially pathogenic bacteria. However, the presence of FIR, and not a positive culture, was associated with adverse neonatal outcomes.

Sci Rep 2023; 13:16206. [PMID: 37758740 PMCID: PMC10533511 DOI: 10.1038/s41598-023-43362-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 09/22/2023] [Indexed: 09/29/2023] Open
Abstract
To investigate whether the increased risk of fetal abdominal obesity (FAO) is present in the older (≥ 35 years) and/or obese (≥ body mass index 25 kg/m2) women with normal glucose tolerance, we reviewed medical record of 6721 singleton pregnancy. At 24-28 gestational weeks (GW), fetal abdominal overgrowth was assessed by the fetal abdominal overgrowth ratios (FAORs) of the ultrasonographically estimated gestational age (GA) of abdominal circumference per actual GA by the last menstruation period, estimated GA of biparietal diameter or femur length, respectively. FAO was defined as FAOR ≥ 90th percentile. Compared to young and non-obese women, older women showed significantly higher FAORs irrespective of obesity and the prevalence of FAO in older and non-obese women was significantly higher (11.8% vs. 8.6%, p < 0.05). The odds ratio for large for gestational age at birth were 3.06(1.96-4.77, p < 0.005), 1.47(1.16-1.86, p < 0.005) and 2.82(1.64-4.84, p < 0.005) in young and obese, older and non-obese, and older and obese women, respectively. The odds ratio for primary cesarean delivery in older and non-obese women was 1.33 (1.18-1.51, p < 0.005). An increased risk of FAO at 24-28 GW and subsequent adverse perinatal outcomes have been observed in the older women with or without obesity, compared to younger and non-obese women, despite normal glucose tolerance.

[PMID: 37062508 DOI: 10.1016/j.ajogmf.2023.100972] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 04/05/2023] [Accepted: 04/09/2023] [Indexed: 04/18/2023]
Abstract
BACKGROUND With the rise in the number of women giving birth at an advanced age, the association between advanced maternal age and adverse obstetrical outcomes is a growing concern in developed countries. Despite the well-established link between advanced maternal age and pregnancy-related complications, there has been limited research examining the specific risks related to unscheduled cesarean delivery in nulliparas at term. OBJECTIVE This study aimed to evaluate the risks associated with unscheduled cesarean delivery in nulliparas at ≥37 weeks of gestation, comparing the outcomes of younger patients with those aged ≥40 years. STUDY DESIGN This retrospective cohort study was conducted in a tertiary maternity hospital in Switzerland (high-income country). The study included nulliparas who delivered a live-born infant at ≥37 weeks between January 2015 and December 2019. We excluded pregnant women who had a planned cesarean delivery, were aged <18 years, multiparous, delivered before 37 weeks of gestation, or had pregnancies that ended in stillbirth. Participants were divided into 2 age groups: (1) ≥40 years and (2) <40 years. The primary outcome was the incidence of unscheduled cesarean delivery. Its association with advanced maternal age was evaluated after adjusting for confounding factors by multivariate logistic regression, expressed as an adjusted odds ratio. Secondary outcomes included pregnancy outcomes and neonatal outcomes. RESULTS A total of 5211 patients were included: 173 in the ≥40-years (advanced maternal age) group and 5038 in the <40-years (non-advanced maternal age) group; 26.01% (95% confidence interval, 19.65-33.22; n=45) of women in the advanced maternal age group had an unscheduled cesarean delivery, whereas 15.26% (95% confidence interval, 14.28-16.29; n=769) of women in the non-advanced maternal age group underwent the procedure. Advanced maternal age was associated with unscheduled cesarean delivery, with an adjusted odds ratio of 1.51 (95% confidence interval, 1.06-2.17; P=.024). Among vaginal deliveries, assisted procedures were performed on 29.7% (95% confidence interval, 21.9-38.4; n=38) of advanced maternal age patients vs 20.1% (95% confidence interval, 18.9-21.3; n=856) of non-advanced maternal age patients. Postpartum blood loss >1000 mL occurred in 5.8% (95% confidence interval, 2.8-10.4; n=10) of advanced maternal age patients and 3.1% (95% confidence interval, 2.6-3.6; n=156) of non-advanced maternal age patients. CONCLUSION Advanced maternal age is associated with increased risk of unscheduled cesarean delivery among nulliparas. This provides healthcare professionals with confirmation that advanced age may represent an individual risk factor, suggesting that nulliparous patients aged over 40 years may benefit from improved information regarding the factors contributing to this pregnancy outcome.

World J Diabetes 2022; 13:776-785. [PMID: 36188149 PMCID: PMC9521439 DOI: 10.4239/wjd.v13.i9.776] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 07/01/2022] [Accepted: 08/01/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Gestational diabetes mellitus (GDM) refers to abnormal glucose tolerance during pregnancy, and it is often accompanied by obvious changes in glucose and lipid metabolism, and associated with adverse pregnancy outcomes. The incidence of fetal distress, polyhydramnios, puerperal infection, premature delivery, and macrosomia in pregnant women with GDM are higher than in those without GDM.
AIM To analyze the relationship between age of pregnant women with GDM and mode of delivery and neonatal Apgar score.
METHODS A total of 583 pregnant women with GDM who delivered in the Department of Obstetrics at our hospital between March 2019 and March 2022 were selected. Among them, 377 aged < 35 years were selected as the right age group and 206 aged > 35 years were selected as the older group. The clinical data of the two groups were collected, and the relationship between age of the pregnant women with GDM and mode of delivery, maternal and neonatal outcomes, and neonatal Apgar score were compared. In the older group, 159 women were classed as the adverse outcome group and 47 as the good outcome group according to whether they had adverse maternal and infant outcomes. The related factors of adverse maternal and infant outcomes were analyzed through logistic regression.
RESULTS The number of women with assisted pregnancy, ≤ 37 wk gestation, ≥ 2 pregnancies, one or more deliveries, and no pre-pregnancy blood glucose screening in the older group were all higher than those in the right age group (P < 0.05). The natural delivery rate in the right age group was 40.85%, which was higher than 22.33% in the older group (P < 0.05). The cesarean section rate in the older group was 77.67%, which was higher than 59.15% in the right age group (P < 0.05). The older group had a higher incidence of polyhydramnios and postpartum hemorrhage, and lower incidence of fetal distress than the right age group had (P < 0.05). There was no significant difference in neonatal weight between the two groups (P > 0.05). The right age group had higher Apgar scores at 1 and 5 min than the older group had (P < 0.05). Significant differences existed between the poor and good outcome groups in age, education level, pregnancy mode, ≤ 37 wk gestation, number of pregnancies, and premature rupture of membranes (P < 0.05). Logistic regression showed that age, education level and premature rupture of membranes were all risk factors affecting the adverse outcomes of mothers and infants (P < 0.05).
CONCLUSION Delivery mode and Apgar score of pregnant women with GDM are related to age. Older age increases the adverse outcome of mothers and infants.
