Filter by:This project will test the efficacy of a balanced protein energy supplement for daily use during pregnancy and the first 6 months after delivery on the outcomes of pregnancy and growth of infants during the first 6 months of life. Approximately 1800 pregnant women from a district in southern Nepal will be recruited and randomly assigned to one of 4 groups, control in pregnancy & post-partum, supplementation in pregnancy & control post-partum, control in pregnancy & supplementation post-partum, or supplementation in pregnancy & post-partum. Pregnancies will be followed until delivery and the infants through 6 months of age. Outcomes of interest include birth size (weight and length), gestational age at delivery, maternal weight gain in pregnancy, maternal weight at 6 months post-partum, infant growth, and breast milk composition.
The main goal is to determine which risk factors develop preeclampsia in this specific group of oocyte recipients.
Many preterm, low birth weight and other high-risk infants are surviving the early neonatal period. However, upon discharge from the neonatal units, this at-risk population has little support for their health, nutrition and development in the community. To address this emerging need, Partners In Health in collaboration with the Ministry of Health and UNICEF, has created a pediatric developmental clinic (PDC) to follow the high-risk infants after discharge from hospitals and health centers.
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.
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
Performing an additional non-invasive oocyte diagnostic test based on cumulus cell gene expression could improve the outcome of the ART cycle
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.
The objectives of this application are to provide mechanistic understanding of altered drug metabolism by hepatic cytochrome CYP3A4 and to translate the findings to human pregnancy. A drug metabolized by CYP3A4, Quetiapine, will be the drug of choice mechanism to understand the enzyme's induction. Pregnant women currently on Quetiapine will be recruited. If the women enroll, the women will participate in four pharmacokinetic (PK) studies (one per trimester, and one postpartum).
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.
The purpose of this study is to collect whole blood samples from women with viable pregnancies of at least 10 weeks gestation (at any risk for fetal chromosomal anomaly) for future testing with an investigational noninvasive prenatal test(s) (NIPTs), and to establish clinical truth compared to a clinical reference standard.
