Active clinical trials for "Pregnancy Complications"

Breech presentations (where a baby presents with feet or bottom down) have an increased risk of perinatal and neonatal complications, and are usually delivered by cesarean section. As an alternative, so that the baby can be delivered vaginally, an attempt can be made to turn the baby so that it is head down: this manoeuvre is called an external cephalic version (ECV). Drugs that relax the uterus (tocolytic agents) are sometimes used to help improve ECV success rates. Nitroglycerin is a tocolytic agent, but intravenous nitroglycerin has not been tested as an agent to help ECV. There is some suggestion that nitroglycerin may be more helpful in women who have not previously been pregnant (nulliparous women) than in women who have been pregnant more than once (multiparous women), and so we have planned two trials. This study is designed to answer the following questions for multiparous women: Will administration of IV nitroglycerin for uterine relaxation improve ECV success rates? Will an increase in ECV success result in a decreased cesarean section rate?

PregSource uses a crowd-sourcing approach, asking pregnant women to enter information regularly and directly about their pregnancies throughout gestation and the early infancy of their babies into online surveys and trackers via a website and/or mobile application ("app"). In exchange, participants can track their data over time, print out reports to share with their healthcare team, and see how they compare to other women. In addition, PregSource will provide participants with links to trusted, evidence-based information about pregnancy management, issues, and complications.

Purpose: The emergence of a new coronavirus SARS-CoV-2 causing a novel infection in the human race resulting in a world-spanning pandemic came as a surprise and at a tremendous cost both for individual human lives as well as for the society and the health care sector. The knowledge on how this new infection affects both the mother and the unborn child as well as the outcomes for the mother and the child in the long run are unknown. What is known is based on case-reports and small case-series solely. Both the coronaviruses causing Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) can cause a threat to pregnant women and their offspring, which leads to the question whether this could be the case also for SARS-CoV-2. Aims: To establish a biobank of biological material from infected as well as non-infected pregnant women and their offspring. To combine this biobank with Swedish quality and health care registers, computerized patient charts and questionnaire data, enabling both short-term follow up, such as obstetric outcomes, as well as long-term outcomes both for mother and child. To study how the pandemic situation affects both the mother and her partner in their experience of pregnancy, childbirth, and early parenthood. Design: A national Swedish multicentre study. Women are included when they have a positive test for SARS-CoV-2 or a clinical suspicion of coronavirus disease 2019 (COVID-19) (COVID-19 group). Pregnant women without COVID-19 symptoms will be included at their routine visits (Screening group). Blood samples and other biological material will be collected at different time-points. Additional predictors and outcomes are collected from the Swedish Pregnancy Register as well as obligatory Swedish health registers. The biobank and its linkage to health registers through the Swedish personal identification number will enable future research. Child development will be followed during the first year of life by questionnaires to the parents. Womens' and their partners' experience of childbirth and parenthood will be studied in form of questionnaires as well as in form of interviews. Conclusion: This project will help obstetricians and neonatologists better recognize clinical manifestations of the virus, identify possible risk factors during pregnancy and tailor therapies alongside providing right level of surveillance and management during pregnancy, delivery, and child health care.

Fear of childbirth, or what has historically been called tokophobia, is often described as a severe fear of birth and pathological fear of childbirth. The reasons for fear of childbirth are stated as biological reasons, psychological reasons and lack of social support. However, it is still not possible to clearly explain the reasons for the fear of childbirth in pregnant women and the risk factors affecting them. The reasons for the fear of childbirth and the affecting factors have not been fully explained.

This study aims to characterize the association between history of pregnancy complications and M2 carrier status in IVF patients and the utility of M2 haplotype preimplantation genetic testing (PGT) in embryos produced by carrier couples. Participants in this study will be screened for the M2 variant. History of pregnancy complications and miscarriages will be studied in order to determine potential associations with M2 carrier-ship.

This will be a retrospective observational cohort study utilizing the data from the British Columbia Perinatal Data Registry (BCPDR). The BCPDR is a provincially inclusive database that aggregates obstetrics and neonatal variables from all attended births in British Columbia. The primary objective of this study is to evaluate and contrast the average time interval from the first to second birth for patients with recurrent pregnancy loss compared to healthy controls. Secondarily, the investigators will calculate the cumulative live birth rate in the cohort of women with recurrent pregnancy loss who were </= 35 at age of first birth and delivered between the years 2000-2010. Finally, the investigators will compare the incidence of adverse perinatal outcomes for those with recurrent pregnancy loss and those without. The results of this study will be valuable for clinicians and patients as it will provide information for prognosis counselling. This will also help those desiring more than one child with long term family planning.

In patients with suspected placental vascular disease who do not require hospitalization, the use of the sFlt-1 (Soluble FMS like tyrosin-kinase-1)/PlGF (Placental Growth Factor)/ assay can most likely help teams to define the best possible management.

Preterm birth is the leading cause of neonatal death and a significant cause of life long disability and health problems. It has been shown that the drug 17-hydroxyprogesterone caproate can help reduce the risk of preterm delivery in women with certain risk factors for preterm birth. We hope to learn whether this same medication can be used to prolong pregnancy in a group of patients in whom this medication has not been previously studied. Specifically, we hope to learn whether progesterone supplementation will delay delivery in women with pre-term, premature rupture of membranes (PPROM).

For every case of maternal death, many more women experience life-threatening complications during pregnancy and childbirth. Yet, severe maternal morbidity (SMM) cases are often overlooked post-delivery. Women have reported that roughly 15% of SMM cases first occurred in the six weeks following delivery. The underlying factors associated with these morbidities are likely different than those occurring antenatally and at the time of delivery. Further research is required to elucidate the exact burden of SMM in the postpartum period in British Columbia (BC).

There is a lack of consensus on whether women with proteinuric kidney disease benefit from prophylactic anticoagulation during pregnancy to reduce the risk of venous thromboembolism. This pilot study will investigate the feasibility of obtaining thrombosis profile data using a viscoelastic haemostasis monitor - Sonoclot - from pregnant women with kidney disease, and exploratory analyses to elucidate correlations between output values and clinical parameters
