Filter by:A pilot cohort study to preliminarily investigate the efficacy of pretreatment with letrozole 10 mg daily for three consecutive days followed by treatment with misoprostol 800 mcg vaginally for medical management of early pregnancy loss in a US population. Patients will be followed to assess efficacy of this treatment regimen, as well as additional interventions needed, side effects, adverse events, and patient acceptability.
The goal of this observational study is to learn about The purpose of this study was to compare the psychological differences between couples after IVF transplant failure and IVF pregnancy loss, including the differences in anxiety, depression, stress and post-traumatic stress between women and their spouses. The main question it aims to answer is: What are the psychological effects of IVF implantation failure and IVF pregnancy loss on women and the psychological differences between couples? Participants already taking IVF as part of their regular medical care will answer online survey questions about their joint pain for 1 years.
Non-blinded prospective randomized study. 100 women diagnosed with early pregnancy loss up to 10 gestational weeks who opted for surgical management (after being offered the options of conservative management and medical treatment) will be recruited. Qualifying patients will sign an informed consent form and will be randomly assigned to the two arms of the study: 1. Surgical uterine evacuation by the traditional ultrasound-guided suction curettage (control group) 2. Surgical uterine evacuation by operative hysteroscopy using a tissue removal device (study group). The surgical procedure will be determined randomly by computer generated allocation. All surgical procedures will be performed under general anesthesia in an outpatient surgical suite. The operative time, operative blood loss and intraoperative complications will be recorded by the research team. Following the surgical procedure, the patients will be monitored and discharged home as per our department's day-surgery protocol. Immediate post-operative complications will be recorded until discharge. One week after the procedure, a telephone interview will be conducted to assess any procedure-related complications. A diagnostic hysteroscopy without anesthesia will be scheduled 6 weeks postoperatively to assess for retained products of conception and for intrauterine adhesions. The diagnostic hysteroscopy will be performed by a practitioner who will be blinded to the type of surgery performed. 6 months after the procedure, a telephone questionnaire will be conducted to assess for subsequent pregnancies.
Based on the comprehensive etiological screening results of patients with recurrent pregnancy loss, including basic characteristics, coagulation function indicators, autoimmune indicators, endocrine indicators, and gynecological ultrasound examination results, as well as the outcome of subsequent pregnancy after the patient's visit, analyze the independent risk factors affecting recurrent pregnancy loss, construct and validate an abortion risk prediction model to predict the risk of subsequent pregnancy loss in patients with recurrent pregnancy loss, and classify the patient's risk, Screening high-risk populations and guiding clinical early intervention and active treatment to improve pregnancy success rates.
This observational study aims to compare the prevalence of acquired abnormalities of the uterus (fibroids, polyps, intrauterine adhesions, adenomyosis) in women who have recurrent miscarriages with the fertile population.
The aim of the study is to estimate the incidence of CE, evaluate the endometrial microorganism of CE, and investigate the therapeutic benefits of antibiotics for women with unexplained recurrent miscarriage and CE.
Chronic histiocytic intervillositis (CHI) is a rare condition with an incidence of 5 in 10,000 pregnancies. This rare condition is associated with placental inflammatory lesions leading to severe and recurrent obstetrical complications: intrauterine growth retardation (IUGR), fetal death in utero and miscarriage. The pathophysiological mechanisms of CHI are poorly understood, while the empirical treatments prescribed to prevent recurrence are cumbersome and of poor efficacy. Recent findings suggest that an alloimmune response may play a role. In a recent work, the investigators have demonstrated the role of maternal alloantibodies directed against fetal HLA antigens in two patients followed for recurrent IUGR associated with CHI. Their work suggests that a humoral alloimmune response directed against fetal HLA antigens mimics an allograft rejection process. The investigators propose to extend the preliminary results obtained in these patients to provide new insights into the pathophysiological mechanisms of CHI, and eventually to predict the risks of fetal loss.
The definition of recurrent spontaneous abortion (RSA) has changed over the years, and most societies now advocate defining RSA as two or three consecutive or discontinuous miscarriages with the same sexual partner before 24 weeks gestation In recent years, the incidence of this disease has been on the rise, occurring in about 1%- 5% of pregnancy in women at childbearing age, and the success rate of second pregnancy in RSA females has been significantly reduced The etiology of RSA is extremely complex, including anatomical factors, genetic factors, endocrine factors, infectious and immune factors, and pre-thrombosis etiology. However, the cause of the disease is unclear in half of patients and known as unexplained recurrent spontaneous abortion (URSA)
Miscarriage is a very common complication of pregnancy, accounting for 15.3% (95% CI 12.5-18.7%) of diagnosed pregnancies. Miscarriage would affect one in ten women during her lifetime. Worldwide, 23 million miscarriages occur annually. Because of its frequency, miscarriage isoften considered as trivial event by caregivers. Still, miscarriage can be a traumatic event. Literature is consistent on the psychological morbidity associated with miscarriage. Anxiety, depression, post-traumatic stress have been studied in women after miscarriage. Cohort studies and clinical trials suggest that psychological and supportive interventions performed in women after miscarriage may improve women's psychological well-being and reduce miscarriage complications in subsequent pregnancies. However, to date, the literature is considered insufficient on the psychological care of women after a miscarriage.
Recurrent pregnancy loss (RPL) is defined as 2 or more consecutive miscarriages1 This condition affects about 1-3% of couples during their reproductive years. The role of vaginal infections in RPL is controversial and microbiological screening is not recommended as per the international guidelines. Current theories suggest that altered vaginal and uterine microbiota may trigger an inflammatory response in the endometrium even without the presence of clinical infection which could affect the success of embryo implantation and future development of pregnancy2 .Changes in the uterine microbiota can lead to chronic endometritis (CE). This condition is caused by continuing inflammation of the endometrium, involving a variety of common bacterial and yeast species and has been associated with RPL3 . Notably, CE can be found in up to 45% of infertile patients4. Current diagnosis of CE is based on histopathological examination, immunohistochemistry assay for CD138 cells and morphological appearance on hysteroscopy. While antibiotic treatment can improve ongoing pregnancy rates in patients with RPL treatment success is still partial and unpredictable. A mechanistic link is yet to be established between vaginal and uterine microbiota and RPL and it is unknown whether restoration of the microbiome in patients with RPL can improve pregnancy outcomes.
