The Mediterranean-style diet has been associated with longevity, long-life wellbeing, lower risk of cardiovascular disease, cancer, obesity, and metabolic syndrome. Research is pointing to the benefits that MeD could have in pregnant. Pregnancy is a very complex period and recently, the attention has been focused on the possibility that healthy dietary patterns positively influence pregnancy and the development of organs in the offspring. The mechanisms through which MeD influences pregnancy and fetal growth may partly depend on its antinflammatory properties and possibly on changes in epigenetic mechanisms. Systemic inflammation might contribute to the association between maternal obesity and less favorable neurodevelopmental outcomes. The investigators aim to define how maternal adhesion to MeD may affect pregnancy and new-born development, hence representing a notable burden from a public health and social perspective. Main objective of this project is to build up a birth cohort suitable to investigate the role of maternal dietary habits on maternal and new-born health, with special focus on MeD and its possible mechanism of action through epigenetic and inflammation changes. To establish a mother/new-born cohort, collect detailed information on maternal dietary habits and set-up a biobank of biological samples to evaluate the association between dietary habits and pregnancy outcomes. The investigators will recruit 2000 pairs (mother, new-born) in different obstetrics departments. To investigate the association between maternal dietary habits, foetal growth and offspring development and possible mediation by the inflammation profile of the mother. To understand whether maternal dietary habits are associated with epigenetic changes in the offspring and if this process is driven by the inflammation profile of the mother. Venous blood samples will be obtained at the baseline and at each gestational period for ultrasound at 11-13 gestational weeks, 20-22 weeks and 30-32 weeks. Women will be followed-up with standard clinical and 2D ultrasound examinations at gestational weeks 11-13, 20-22 and 30-32 to evaluate the fetal growth. Offspring development will be assessed at 6, 12, 18, 24 months of age. After delivery, the investigators will collect umbilical cord blood and saliva samples from new-born using standard procedures. To understand if new-born epigenetics is associated with infant physical and neurocognitive development in the following 2 years.

Many pregnant people don't get the dental care they need, even though it's safe and important. The CHEER Study offers free dental check-ups, cleanings, and supplies to help participants take care of their teeth and gums during pregnancy. The purpose of this research study is to compare two types of noninvasive oral health interventions to evaluate their effectiveness. We want to learn if one method is more effective in supporting oral health and improving pregnancy outcomes. There are two aims of this study: Aim 1: To evaluate whether a structured oral health intervention reduces periodontal inflammation during pregnancy and postpartum in pregnant people with indicators of periodontal disease. Aim 2: To assess whether a structured oral health intervention is associated with changes in oral health behaviors or birth outcomes in pregnant people with periodontal disease.

The GESTA-COR study is a prospective, non-commercial, randomized clinical trial designed to evaluate the impact of detailed vascular imaging feedback on the management of cardiovascular health in women with a history of adverse pregnancy outcomes (APOs). The trial aims to determine if providing these women with detailed images of their vascular status can encourage the adoption of healthier lifestyles and adherence to preventive treatments, thereby potentially reducing the incidence of postpartum hypertension and other cardiovascular diseases. This study involves two randomized groups: Intervention Group (Randomized): Women with APOs receiving detailed vascular imaging results. Standard Management Group (Randomized): Women with APOs who will continue receiving standard health information without vascular imaging results. Participants will be monitored for 12 months postpartum, focusing on blood pressure levels, cardiovascular health indicators, and lifestyle changes.

The objective of this study is to describe and compare the incidence of adverse pregnancy outcomes (spontaneous abortion/miscarriage, stillbirth) and prevalence of adverse infant outcomes (major congenital malformations \[MCMs\], small for gestational age \[SGA\]) in women with AD who are treated with dupilumab during pregnancy relative to women with AD who are not treated with dupilumab during pregnancy.
NCT06926166
The long-term goal of the Human Genes and Microbiota in Early Life (HuGME) is to explore the short- and long-term effects of maternal microbiota during pregnancy and the microbiota colonization of their offspring early in life and their interaction with the host on maternal-offspring health consequences in later life in the born in Guangzhou cohort study in China. Identification of the effect of microbiota in early life, as well as environmental factors and microbe-host interaction, will lead to a better understanding of disease pathogenesis and provide a foundation for targeted mechanistic investigation into the consequences of microbial-host crosstalk for long-term health. It also can result in new strategies to predict and prevent diseases in later life.

Pathogenic variants (PVs) in the BRCA1 and BRCA2 genes are associated with an increased risk of developing breast and ovarian cancers. According to current guidelines from the National Comprehensive Cancer Network, the risk of developing breast cancer exceeds 60% for both genes, while the risk for ovarian cancer ranges from 39% to 58% for the BRCA1 and from 13% to 29% for the BRCA2. The detection of a pathogenic variant in the BRCA1 or BRCA2 genes necessitates both the establishment of appropriate primary and secondary surveillance measures for carriers and the discussion of the familial implications of such findings. The molecular basis initially suggesting a possible association between germline variants in BRCA1 and BRCA2 genes and diminished ovarian reserve lies in the cellular impact of impaired or defective repair of DNA double-strand breaks (DSBs) on oocytes. Notably, BRCA1 and BRCA2 genes play a key role in the ATM-related mechanism for DSB repair through the homologous recombination (HR) pathway. Although preclinical evidence supports a potential correlation between defective DSB repair and normal follicle maturation processes, clinical studies on large cohorts of patients with pathogenic BRCA1 and BRCA2 variants yield inconsistent results. This discrepancy is likely attributable to the inherent challenges in recruiting a sufficiently homogeneous and statistically significant sample size. The aim of the study is to evaluate reproductive capacity in women carrying pathogenic variants in the BRCA1/2 genes by assessing the number of pregnancies during the period from January 1, 2018, to December 31, 2023. Secondary objectives include evaluating menopausal characteristics and pregnancy outcomes.

1 Materials and methods 1.1 Subjects From September 2021 to August 2022, the patients who received induction of labor by cervical double balloon combined with oxytocin in a Grade III A Maternal and Child Health Hospital in Changsha were included in the study. A double balloon and oxytocin induced labor at a tertiary maternal and child health centre in Changsha. Inclusion criteria: 1 age ≥18 years; 2 Singleton; 3 no vaginal infection, fetal membranes intact; 4 according with the indication of induced labor \[5\] ; These included delayed pregnancy, hypertensive disorder complicating pregnancy, diabetes mellitus, cervical Bishop score \< 6, and negative oxytocin provocation test (Oct) . The exclusion criteria were: 1 abnormal head and pelvis, unable to be delivered vaginally; 2 twins; 3 maternal contraindication of vaginal delivery; 4 severe placental dysfunction, unable to tolerate vaginal delivery; 5 there were contraindications for the use of cervical balloon. 1.2 Methods 1.2.1 Operation Method First of all, pregnant women to introduce the procedure of placing the balloon, ease their fear, tension. Assist the patient to take the stone position, sterilize vulva 3 times, spread aseptic towel, expose cervix with vaginal speculum, sterilize vagina and cervix 3 times with iodine cotton ball, after sterilizing the cervical tube 3 times with iodine-complexed cotton swab, insert the disposable dilatation balloon (Henan Bonding Industry Co., Ltd., Yusheng Medical Supervision Machine No. 20180029, model: Type II 18F) into the cervical tube, until the two sacs into the cervical canal and ensure that the double sacs are through the cervical mouth, sub-turn to the cervical inside and outside sacs slowly injected saline 80 ml each. The end of the balloon catheter was fixed to the inner thigh of the pregnant woman with 3m adhesive tape, without restricting the physical activity of the pregnant woman. The operation process is smooth, the pregnant woman has no discomfort, before and after the operation monitoring fetal heart is normal, instructs the pregnant woman to test the fetal movement, closely observes the pregnant woman labor sign and the fetal intrauterine situation. The balloon is usually inserted between 16:00 and 18:00. The balloon is taken out at 8:00 am the next day, oxytocin (Ringe 500ml + oxytocin 2.5 U) was given intravenously to the patients who were not in Labor 1 hour after rupture of membranes. According to the frequency of uterine contractions, if there is no uterine contractions, increase the rate of dripping 8 drops/min, maximum dose not more than 40 drops, until regular uterine contractions, after every half-hour assessment. 1.2.2 Observation indicators Using the hospital electronic medical record information system to search and review the medical records of these women, the age, number of pregnancies, number of parturients, weight gain during pregnancy, height, weight, pre-and post-pregnancy body mass index (BMI) , indication of induced labor, pregnancy complications, gestational age at the time of balloon induced labor, neonatal weight, cervical Bishop score before and after balloon dilatation, occurrence of acute Chorioamnionitis, fetal distress, NST typing, mode of delivery, etc. . The clinical data of the patients who were induced by cervical double balloon combined with oxytocin were analyzed, and the related factors of pregnancy outcome were also discussed. 1.3 Statistical credits SPSS 25.0 was used to analyze the data. The mean ± standard deviation was used for statistical description and t-test was used for statistical analysis. The frequency was used for statistical description and chi-square test was used for statistical analysis. Binary logistic regression analysis was used to determine the influencing factors of different pregnancy modes, and the difference was statistically significant with P \< 0.05.

Since the incidence of maternal obesity and gestational diabetes mellitus (GDM) is on the rise globally, how to improve the intrauterine environment of the offspring and prevent obesity and metabolic diseases from the early life has become a medical research. Since 2012, journals such as Nature and Science have reported that intestinal micro-ecological environments composed of intestinal microbes and their interactions are involved in human body and energy metabolism, and a variety of metabolic diseases including obesity and type 2 diabetes mellitus (T2DM). The incidence is closely related. Although intestinal microbes have an important impact on human health, the research on intestinal microecology during pregnancy is still in its infancy. The current research is still unclear about the relationship between intestinal microecology and pregnancy outcomes and whether it can be a potential target for regulating maternal metabolism and fetal intrauterine environment. Therefore, this study aims to regulate overweight/obese pregnant women by using prebiotic-containing dairy products to explore the effects of interventions targeting intestinal microbes on glucose and lipid metabolism, insulin resistance and risk of GDM in overweight/obese pregnant women. In order to improve the intrauterine environment and reduce the risk of fetal diseases. It is of great significance and value to improve the quality of the birth population in China and to alleviate the medical economic burden caused by obesity and metabolic diseases.
