The aim of the study is to assess the efficacy and safety of an innovative two-hand (hand forceps) fetal head extraction technique during the transverse cesarean sections (LTCS) by comparing with the conventional one-hand technique used worldwide for centuries. The primary research question of the study is whether two-hand fetal head extraction technique results in quicker head delivery. The secondary research question is whether two-hand technique would cause increased incidence of extension of uterine incision as well as other adverse events while compared to conventional one-hand technique. Our hypothesis is that two-hand technique would speed up fetal head delivery without increasing the risk of extension of uterine incision as well as other adverse events, in the meantime, maternal discomfort will be significantly reduced since fundal pressure will not be required during the fetal head delivery.
Uterine natural killer (uNK) cells have been implicated to play a role in female reproductive performance. Serval studies showed an increased uNK cell density in the endometrium of women with reproductive failure. In this study, we wish to investigate the density and clustering of four different immune cells.
Purpose: Determine the effects of maternal docosahexaenoic acid (DHA) supplementation during pregnancy on levels of DHA, synaptamide (novel anti-inflammatory metabolite), and inflammatory biomarkers during pregnancy and at delivery Research Design: Double blind randomized placebo-controlled study of maternal DHA supplementation during pregnancy. Methodology /Technical Approach: Investigators plan to enroll 100 pregnant women with a high risk pregnancy related to (1) a pre-pregnancy Body Mass Index (BMI) of ≥30.0 kg/m2 and/or (2) a history of prior preterm delivery at ≤35+6 weeks gestation. Women will be enrolled between the 8th and 14th week of pregnancy and randomized to receive a once daily DHA supplement (DSM Nutritional Products, Columbia Maryland, DHA capsule 441mg/cap) or a placebo (DSM Nutritional Products, Columbia Maryland, Corn Oil/Soybean oil 50/50 mix) for the duration of the pregnancy. DHA is an omega-3 long chain polyunsaturated fatty acid (LCPUFA) and placebo composed of omega-6 LCPUFA's. Investigators will measure maternal levels of plasma DHA, Synaptamide and inflammatory biomarkers at enrollment, at 26-30 weeks of pregnancy, and from cord blood at delivery. Sociodemographic and clinical characteristics will be collected for each mother from pregnancy onset until discharge following delivery. The infant health record and parental report will be reviewed to record clinical data from birth to 12 months corrected age for short term health outcomes potentially related to inflammation-related morbidities, including growth and development, acute infection requiring hospital admission, and any allergic disorder. All plasma samples will be processed at Dr. Kim's NIAAA/NIH laboratories using high-performance liquid chromatography with tandem mass spectrometry
The purpose of this study is to compare time to completed abortion between two protocols for patients seeking medication abortion - same-day start versus delay-for-diagnosis - in the setting of asymptomatic, low-risk, pregnancy of unknown location.
This study will utilize a prospective, observational, exposure cohort design to examine pregnancy and infant outcomes in women and infants who are exposed to tildrakizumab during pregnancy to treat an approved indication. The pregnancy registry cohort study will be conducted by the Organization of Teratology Information Specialists (OTIS), which is a network of university and health department based information centers serving pregnant women and healthcare providers throughout North America. These services provide a basis for collaborative research such as this Registry. These Services located throughout the United States (US) and Canada will serve as a source of referrals not only for tildrakizumab-exposed pregnancies but also for similarly ascertained disease-matched comparison pregnant women who have not used tildrakizumab in pregnancy. The target follow-up period will be until end of pregnancy and 1 year of age for live born infants.
In vivo and ex vivo study of trophoblastic angiogenic trophoblastic function in placentas from normal pregnancies, at term
Dramatic physiological, psychological, and social changes during the antenatal period may significantly affect a woman's psychosocial and physical conditions, thereby resulting in stress, anxiety, and depressive symptoms. Cognitive behavior therapy (CBT) is a well-established effective psychotherapy to modify thoughts, beliefs, and perceptions, as well as change the behavioral patterns under numerous conditions. However, at-risk women that need access to CBT are challenged by many issues, such as insufficient therapists, stigmatization, long waiting times, and high costs. Preventive strategies may offer a more acceptable means of addressing the problem. Internet-based CBT can help overcome some barriers to improve psychological well-being by providing a timely and efficacious intervention that is customizable, cost-effective, and flexible in terms of time and geography. Hypotheses Compared with the control group, 1. Women who completed an internet-based CBT (MoodUP) will have significantly lower scores for stress, anxiety, and depressive symptoms immediately post-intervention and at 12 weeks post-intervention; 2. Women who completed MoodUP will reduce the frequency of negative automatic thoughts, achieve a better sleep quality, life satisfaction, and mental health immediately post-intervention and at 12 weeks post-intervention; 3. Women who completed MoodUP will have better client satisfaction. Approach A two-stage research design will be used for 3 years. Stage I will consist of the development and validation of MoodUP based on theoretical and empirical rationales. The development of MoodUP will be guided by a combination of the basic principles from behavioral and cognitive psychology. Essential components, teaching strategies, and technical elements of MoodUP will be established according to literature review and a meta-analysis by the principal investigator and her team. Ethical and quality standards will be assessed using the Health on the Net code of conduct and the Health-Related Website Evaluation Form, respectively. Stage II will be used to evaluate the efficacy of MoodUP among 143 antenatal women using a randomized controlled trial, two-armed parallel group pretest, and repeated post-test following the Consolidated Standards of Report Trials guidelines for an internet-based intervention. Primary outcomes will be the presence and severity of antenatal stress, anxiety, and depressive symptoms using the 21-item Depression Anxiety Stress Scale. Secondary outcomes will be automatic thoughts, sleep disturbance, life satisfaction, mental well-being, and client satisfaction, as determined by the 30-item Automatic Thoughts Questionnaires, four-item Sleep Disturbance subscale of the Medical Outcomes Study Sleep Scale, the five-item Satisfaction with Life Scale, the WHO five-item Well-Being Index, and the seven-item Client Satisfaction Questionnaire, respectively. Multivariate analysis of variance with repeated measures will be used to compare the mean difference of scores in the three-time points through Wilks's lambda test. The data will be analyzed according to the intention-to-treat principle with baseline values imputed for missing follow-up data.
The aims of this study are: - To assess the performance of third-trimester ultrasound scan in the localization of intestinal structures (small bowel, gut, mesenteric vessels..) involved in malrotations with a higher-risk of volvulus compared to a gold standard based on fetal MRI. - To describe normal meconium progression (ultrasound and MRI), prenatal anatomical variants of the fetal digestive tract, and interobserver agreement on prenatal ultrasound.
The aim of this study is to correlate and identify the biochemical markers which may reflect WOI. Blood samples will be collected and endometrial biopsy will be performed at particular time points.
