NCT ID: NCT03673007 Recruiting - Pregnancy Clinical Trials

Michigan Contraceptive Access, Research, and Evaluation Study

Start date: September 12, 2018
Phase: N/A
Study type: Interventional

M-CARES will use large-scale administrative data complemented by follow-up surveys and a randomized control trial (RCT) to estimate the causal impact of greater financial access to contraception on a comprehensive set of outcomes. Outcomes include contraceptive use, pregnancy, childbearing, and parenting strategies; partnership decisions and relationship quality; health and health care use; education, labor market success, and public assistance receipt; financial security; neighborhood quality; mental health and stress; and life plans. The resulting estimates will inform a more complete understanding of the costs and benefits of financial access to contraception and, therefore, the investment value of related policies and programs.

NCT ID: NCT03670537 Completed - Pregnancy Clinical Trials

The purpose of the study is to see the percentage of non-anemic, first trimester gravidas presenting to their obstetricians, who are iron deficient.

NCT ID: NCT03668184 Recruiting - Pregnancy Clinical Trials

What Are the Predictive Factors for Preeclampsia in Oocyte Recipients? - PREROVE

Start date: February 1, 2018
Study type: Observational

The main goal is to determine which risk factors develop preeclampsia in this specific group of oocyte recipients.

NCT ID: NCT03663517 Completed - Pregnancy Clinical Trials

Gestational Age Specific Thyroid Function Reference Range

Start date: July 2, 2014
Study type: Observational

It has been well accepted that maternal thyroid dysfunction has adverse affects on both mothers and fetuses. However, the dramatical changes during pregnancy make the interpretation of thyroid function test (TFT, i.e. free triiodothyronine [FT3], free thyroxine [FT4] and thyrotropin [TSH]) very difficult. Previous studies have shown that the level of thyroid hormones differs from non-pregnant population and varies from gestational ages. Moreover, studies have shown the agreement among different instrument platforms was quite low. This study is aimed to determine gestational age specific TFT reference ranges of the local pregnant population for all available platforms currently used under Hospital Authority and Department of Health.

NCT ID: NCT03660007 Completed - Pregnancy Clinical Trials

Incidence of Pulmonary and Venous Thromboembolism in IVF Pregnancies After Fresh and Frozen Embryo Transfer

Start date: January 1, 1992
Study type: Observational [Patient Registry]

In vitro fertilization (IVF) is associated with an increased risk of venous thromboembolism and in particular pulmonary embolism during the first trimester. It is not known whether this increased risk of pulmonary embolism is present both after fresh and frozen embryo transfer. Objective: To assess whether the risk of pulmonary embolism and venous thromboembolism during the first trimester of IVF pregnancies is associated with both fresh and frozen embryo transfer. A population-based cohort study with linked data from nationwide registries on women in Sweden giving birth to their first child 1992-2012

NCT ID: NCT03659786 Active, not recruiting - Pregnancy Clinical Trials

Single-center Prospective Cumulus Cell Test Study

Start date: October 2013
Phase: N/A
Study type: Interventional

Performing an additional non-invasive oocyte diagnostic test based on cumulus cell gene expression could improve the outcome of the ART cycle

NCT ID: NCT03659708 Not yet recruiting - Pregnancy Clinical Trials

Pregnancy and Risk of Venous Thromboembolism

Start date: November 2018
Phase: N/A
Study type: Interventional

The management of venous thromboembolism (VTE) risk in pregnancy still remains a challenge. An individual assessment of the VTE risk is crucial for optimal thromboprophylaxis, but there is no validated tool to help clinicians stratify the risk in pregnant women and introduce prophylactic anticoagulation at the appropriate time. Recommendations mostly based on case-control studies and expert opinions do not accurately reflect the physician's need. In view of the lack of international recommendations with a high level of evidence regarding prophylactic treatment of pregnant women at risk of thrombosis, the use of a risk stratification tool that takes all individual risk factors for VTE into consideration and which aids decisions over prophylaxis regimens may help. Investigators have previously described a VTE risk score (the Lyon-VTE-score), rating patients at increased risk of VTE and recommending individually tailored management. A retrospective evaluation of the initial score showed favorable outcomes in pregnancies with a high risk of thrombosis. A subsequent multicenter prospective study reported promising results using this score and related management strategy. The efficacy and safety after 10 years of prospective use of the Lyon-VTE-score in daily practice to guide the prescription of antithrombotic prophylaxis during pregnancy was recently evaluated and the results showed that the Lyon-VTE-score allows a standardized approach with objective criteria and can help non-specialized centers and young doctors manage these high-risk pregnancies. The results of previous studies provide consistent conclusions on the safety and efficacy of the approach of investigators and give background for a medico-economic study to evaluate costs and consequences of this procedure. The most recent study (2005) evaluating the cost of prophylaxis in pregnant women, evaluated this cost as $1292 for each 6-week cycle of treatment. In addition, the use of such a score offers the prospect of personalized medicine, which is probably more cost-efficient compared to "inclusive, equal treatment for all". In antepartum, the decision to administer thromboprophylaxis should be considered on an individual basis with regard to lowering the absolute risk of thrombosis, the inconvenience of daily subcutaneous heparin therapy and the potential risks of bleeding, heparin-induced thrombocytopenia and osteoporosis. An individual assessment of the VTE risk is crucial for optimal thromboprophylaxis, but there is no validated tool to help clinicians to stratify VTE risk in pregnant women and to introduce prophylactic anticoagulation at the right time. Most of the recommendations are grade 2C. They are mostly based on case-control studies and expert opinions and do not entirely highlight the physicians' need. The originality of this approach is the use of a risk stratification tool that takes all individual risk factors for VTE into consideration and that aids the decision-making process of antenatal anti-thrombotic prophylaxis. This study will personalize care using a score to individually assess the risk and propose appropriate prevention. The main objective of this study is to conduct a medico-economic study to evaluate the efficiency of an innovative strategy integrating the Lyon-VTE-score in the management of pregnant patients with venous thromboembolism risk versus standard care.

NCT ID: NCT03632863 Not yet recruiting - Depression Clinical Trials

PDA for Antidepressant Use in Pregnancy

Start date: September 2018
Phase: N/A
Study type: Interventional

Depression in pregnancy is common, affecting up to 10% of women and represents serious risk to mother and infant. Unfortunately, antidepressant medication, a first-line treatment for depression in pregnancy, also comes with risks, making this a complex decision. Clinical care appears to be insufficient for ensuring that women make decisions that are consistent with their own values and with which they feel satisfied. Patient decision support tools can address such barriers. We have created and piloted with positive results an online patient decision aid (PDA) that has the potential to improve the decision-making process for women regarding antidepressant use in pregnancy in conjunction with clinical care. The overall objective of this study is to conduct a Randomized Controlled Trial (RCT) to assess the efficacy of our PDA for antidepressant use in pregnancy.
