Filter by:The project focuses on prevention of major pregnancy and birth related complications : pregnancy-induced hypertension (PIH), gestational diabetes mellitus (GDM), caesarean section (CS), and large-for-gestational-age (LGA), i.e. the birth weight of the baby exceeds the 90% percentile of birth weights for the specific pregnancy duration. The investigators focus on the pre-conception period, i.e. the pre-conception period of the 2nd pregnancy in women with an excessive weight gain during their 1st pregnancy, aiming to decrease the complications rate in their 2nd pregnancy. Women with an excessive gestational weight gain have obtained the extra weight during a rather short period of time, e.g. 20 kilos in the last 4 or 5 months of their pregnancy. This characteristic distinguishes the target group from the general population with overweight/obesity, in whom the extra weight was acquired during many years and independent from a pregnancy, making a behaviour change more complex. The coaching intervention combines face-to-face counselling with the use of a mobile App connected to medical devices (scale and pedometer). The app monitors important indicators (weight, eating behaviour, physical activity, mental wellbeing), provides coaching through established behavioral change techniques, and is specifically tailored for women with excessive weight gain during the previous pregnancy. The goal is to decrease the rate of pregnancy and birth-related adverse outcomes in the next pregnancy by a healthy life style, starting shortly after their 1st delivery and sustained during the next pregnancy.
The purpose of this study is to learn if giving 17-hydroxyprogesterone caproate (17 OHPC) to mothers with preeclampsia diagnosed before 34 weeks gestation improves mother and baby outcomes.
Performing an additional non invasive oocyte diagnostic test based on cumulus gene expression could improve the outcome of the ART cycle.
This study evaluates the intervention of Nut Fish based food, micro nutrients supplementation and pregnancy class to improve maternal and birth outcome. This is cluster randomized trial with two arms. The intervention group will receive Nut Fish based supplementation, multiple micro nutrients, and pregnancy class. The control group will receive government food supplementation, iron folic acid supplementation, and pregnancy class.
Maintenance of a healthy pregnancy depends on an appropriate adaptation and responsiveness of blood vessels, to ensure appropriate blood flow to the fetus during everyday stressors. Previous work by the investigators has demonstrated that during pregnancy, the part of the nervous system responsible for cardiovascular function (the sympathetic nervous system) is hyperactive. The investigators also know that in women who develop high blood pressure during pregnancy that sympathetic nervous system activity is even higher. Yet, very little is known about why this occurs and how this might be affected. Pregnant women are encouraged to be active, yet, less than 15% of women perform sufficient exercise to meet current guidelines. This is important because hyperactivity of the sympathetic nervous system is observed in other inactive populations and has been linked to adverse cardiovascular health outcomes including hypertension, atherosclerosis, heart attack, and stroke. Indeed, in 2011, the American Heart Association stated that inactivity was a risk factor as potent as cigarette smoking for the development of future cardiovascular disease in women. The investigators' work and others have demonstrated that exercise during pregnancy is beneficial for both the mom and baby; however, the effect of prenatal exercise on neurovascular function is not known. If exercise is effective in controlling the increase in sympathetic activity that occurs during pregnancy, or its effects on the cardiovascular system, this may help prevent the development of high blood pressure or other cardiovascular problems during pregnancy.
This is a sample collection study, participants will be required to collect one (if last menstrual period ≥12 months) or two (if last menstrual period <12 months) urine samples and return them to the study site, together with collection sample information. Participants having a menstrual cycle within the last 6 months will also be required to provide follow-up information on pregnancy status and date of next menstrual bleed.
Position of the tip of the inner catheter and air bubbles detection (at time,5min 10min)during embryo transfer influence the pregnancy rate in ICSI cycles .
Our study's principle purpose is to determine whether decreasing waiting time before being seen for antenatal care increases demand for and use of antenatal care services in Mozambique.
The World Health Organization recommends that all high endemic countries for HBV infection based their mother to child transmission prevention strategies on vaccination of all children and administration of immunoglobulins (HBIG) to infants born to infected mothers in the first 24 hours after birth. Lack of access to antenatal screening and to HBIG significantly results in failure of this strategy in many countries. Moreover, despite sero-vaccination, 10 to 15% of infants of mothers that are positive for HBsAg and HBeAg are still infected, as high levels of HBV replication occurring in the third quarter of pregnancy act as a major risk factor. The objective of this study is to assess the effectiveness of an operational strategy to prevent HBV mother-to-child transmission (MTCT) in Cambodia based on the use of rapid tests HBs Ag and HBe Ag to screen HBV infection and a treatment by TDF for patients with a positive HBeAg test with a "test and treat" strategy for those seen for Antenatal Care (ANC) from 24 weeks of amenorrhea. In all cases, vaccination of the newborn will be carried out according to the national protocol in Cambodia i.e. 4 injections at 24 hours, 6, 10 and 14 weeks of age. A phase IV multicenter observational and interventional non randomized prospective study will be conducted in 4 maternity in Cambodia. The primary outcome will be the proportion of active HBV infection in new-born at 6 months of life estimated by HBs Ag positivity. The study will aim to document the acceptability and the operational implementation of the study using rapid tests usable in all health centers and a drug available in all the country thanks to HIV national program. The results will be helpful for Cambodian government in order to implement guidelines and algorithm follow-up for HBV-infected pregnant women.
The aim of the research is to study humoral and cellular immunity in pregnant women for who the level of rubella virus antibodies is weakly positive, equivocal or negative with the usual laboratory technique.
