Filter by:This study aims to provide psychological support to women that experienced an Early Pregnancy Loss (when the loss occurs until the 20 weeks of gestation) using an innovative Virtual Reality prototype and compare the presence and evolution of psychological distress symptoms pre and post-intervention. The main goals of this study are: 1. Evaluate the impact of the proposed VR paradigm in women who suffered a gestational loss in the first 20 weeks of gestation, compared to a control group that follows the usual standard care; 2. Evaluate the usability, user experience, and acceptance of the proposed approach. Participants in the VR group will have an intervention program lasting four weeks, with 3 weekly sessions of 45-60 minutes, using the developed prototype.
The goal of this prospective observational study is to learn about the effect of low molecular weight heparin (LMWH) application on bone mineral density (BMD) and on calcium-phosphorus metabolism in patients with recurrent spontaneous abortion (RSA), and to compare the degree of bone loss and changes in blood calcium and phosphorus in RSA patients and in control groups with normal pregnancy. By monitoring ultrasound BMD and serum indicators related to maternal bone formation and Ca-P metabolism, the association mechanism between long-term use of LMWH, maternal Ca-P regulation and bone loss will be constructed, so as to contribute to clinical treatment and lifestyle guidance during pregnancy in RSA patients.
The objective of this single-center prospective observational study is to clarify the trend of maternal serum 25(OH)D levels before pregnancy and during pregnancy, and to explore the correlation between serum 25(OH)D levels and subsequent pregnancy outcomes of patients with abortion, so as to provide certain scientific evidence for finding the optimal serum level of 25(OH)D and optimal vitamin D supplementation to maintain a healthy pregnancy.
Introduction: Incomplete early miscarriage is defined as early miscarriage with persistent intrauterine material on ultrasound. Intrauterine retention of trophoblastic debris is not an uncommon phenomenon. These retentions may initially be asymptomatic but are often responsible for persistent metrorrhagia and endometritis. This symptomatology often accentuates the psychological distress of patients mourning the pregnancy. Incomplete miscarriages are mainly managed by the gynecological emergency department. The recommendations of the Collège National des Gynécologues et Obstétriciens Français (CNGOF) suggest as a first line of treatment: either surgical management or expectant care. The choice between the two is left to the discretion of the doctor and the patient. there are no clear recommendations as to the choice between hysteroscopy and aspiration. Within the teams, the choice is often made according to the habits and protocols of the service, according to the equipment available and the skills of the gynaecologists. Aim: The main objective is to compare the efficacy of management by endo-uterine aspiration vs. management by hysteroscopy of trophoblastic retention after early miscarriage, at 6 weeks after surgery, by endovaginal ultrasound. Methods: This is a prospective, multicenter, randomized, open-label, two-arms, parallel therapeutic clinical trial comparing hysteroscopy versus endouterine aspiration for the management of trophoblastic retention after spontaneous miscarriage. Patients will be randomized (110 per arm) after verification of eligibility criteria and signature of consent, on the day of the operation: - Arm A: 110 patients treated by operative hysteroscopy - Arm B: 110 patients treated by endo-uterine aspiration
Physiological intracytoplasmic sperm injection (PICSI) is a technique used to select healthy, mature sperm for use in infertility treatment based on their physiological ability to bind to hyaluronan (HA), a natural compound found in the body. The relationship between sperm and hyaluronan can be used a marker of sperm maturity and optimal fertilising potential; this principle can be observed in vitro using a PICSI sperm selection device. The PICSI Dish contains microdots of hyaluronan, which only mature sperm bind to and these are selected by the embryologist prior to use in the intracytoplasmic sperm injection (ICSI) procedure. Recurrent miscarriages following infertility treatment are mainly idiopathic, but can be linked with increased chromosomal abnormalities. PICSI has been shown to result in better embryo development and reduced chromosomal abnormalities, due to selection of mature sperm with low DNA damage. Therefore, PICSI may be a useful tool for reducing the rate of miscarriage following infertility treatment. The recent HABSelect study investigated treatment outcomes following PICSI, and whilst they concluded no effect on livebirth rate, they found a significant association in their secondary analysis between PICSI and reduced miscarriage rate compared to ICSI. The implications of the HABSelect study deserve to be explored further with miscarriage rate assessed as a primary outcome measure. This proof-of-concept randomised-controlled-trial aims to investigate whether PICSI shows some promise that would merit evaluation in a fully-powered trial to assess its efficacy as an advanced sperm selection method for the reduction of miscarriage rate. Eligible study participants will be patients undergoing fertility treatment using ICSI, who have provided consent for PICSI. Patients will be randomly allocated to two groups: the control group will receive ICSI according to standard protocol, and the intervention group will have additional sperm selection by HA-binding in a PICSI dish.
Recurrent miscarriages (RM) affects 3% of all fertile couples, but remains unexplained in most cases, limiting therapeutic options. Possibly the maternal immune system plays a role in recurrent miscarriage. Prednisolone suppresses the immune system and might enable development of normal pregnancy. In this randomized controlled clinical trial the investigators will study the effect of prednisolone on the live birth rate in patients with RM. Secondary, the tolerability and safety for mother and child and the cost-effectiveness is investigated. In the study one group of pregnant women with RM and gestational age <7 weeks will receive prednisolone, the other group will receive a placebo. Total use of the medicine during this study is 8 weeks, further care during the study is routinely antenatal care. Subjects will be asked to fill in 4 short questionnaires and will have contact with a research nurse at different time points to gain information on the course of the pregnancy and possible side effects. Results of the study will be implemented in (inter) national guidelines, to effect everyday practice.
Spontaneous pregnancy loss is a relatively common phenomenon, with 10-15% of clinically recognized pregnancies ending in miscarriage.1 Recurrent pregnancy loss (RPL) is a disorder defined by two or more failed pregnancies2. According to various studies, pregnancy loss has been described as a traumatic event for couples even if the loss occurs at a very early stage of pregnancy. Few controlled studies dealt with the effects of the miscarriage on the psychological condition of women during a subsequent pregnancy, 4,6-8. This study aimed to evaluate the effectiveness of "at home ultrasound" in addition to routine prenatal care in reducing maternal anxiety during pregnancy for patients with history of recurrent pregnancy loss. i.

Implantation is a determining step in human reproduction which requires the transition from a pro-inflammatory state to an anti-inflammatory state allowing the implantation of a competent embryo within a receptive endometrium, and then the maternal immunotolerance towards the alloantigenic fetus. Repeat implantation failures (RIFs), that refers to the fail to achieve a clinical pregnancy after the transfer of at least 3-4 good quality embryos or two blastocysts, and unexplained recurrent spontaneous miscarriage (RM) (≥2-3) could be related in some patients to immune imbalances characterized by an excessive and prolonged inflammatory response and/or a defect of anti-inflammatory regulation. In this context, several therapies have been evaluated in patients with RIFs or RMs in order to restore the immune balance, with heterogeneous results. No serum biomarker assay has been routinely approved to identify patients with immune imbalances that may explain repeated pregnancy failures and to predict the success of the subsequent IVF/ICSI cycle. The immunological analysis on peripheral blood will be based on the determination of the proportions of immune subpopulations (e.g. CD4+ et CD8+, TH1, TH2, TH17, Treg, ILC 1, ILC2, and ILC3) on the one hand and the circulating level of plasma cytokines on the other hand.
The female genital tract microbiome may reflect female reproductive health and may be related to pregnancy outcomes. Disturbances in this microbiome may be associated with adverse reproductive outcomes. The investigators hypothesize that the endometrial and vaginal microbiome composition in women with a history of recurrent pregnancy loss are different, compared with those in normal fertile women.
The Heartland Study is a prospective, observational study that will enroll up to 2,600 pregnant participants across the Heartland States in the U.S.. The objective of the Heartland Study is to address major knowledge gaps concerning the health effects of herbicides on maternal and infant health. The study is being conducted to evaluate the associations between environmental exposures to herbicides during and after pregnancy and reproductive health outcomes. The study is measuring multiple biomarkers of herbicide exposure among pregnant Midwesterners and their partners to evaluate associations with pregnancy and childbirth outcomes, epigenetic biomarkers of exposure, and child development.
