Filter by:Hypertensive disorders of pregnancy are one of the most frequent complications of pregnancy, being a serious health problem around the world. Previous studies have suggested that there is an association between a short period of exposure to paternal sperm of a new sexual partner and the development of an immunological reaction that could trigger a hypertensive disorder of pregnancy. For this reason we want to study the relationship between the primipaternity concept (exposure to male antigens present in semen over a short period of time previous to the pregnancy) and the development of preeclampsia in adolescents.
This study proposes to look at the pharmacokinetics of two drugs (Cefazolin and ondansetron) given routinely to pregnant women who are planning to deliver via cesarean section. The investigators will evaluate the metabolism of both drugs by the pregnant woman, the placental transfer over time, and the subsequent metabolism of the transferred drug in the neonate.
To determine the efficacy of high dose folic acid supplementation for prevention of preeclampsia in women with at least one risk factor: pre-existing hypertension, pre-pregnancy diabetes (type 1 or 2), twin pregnancy, preeclampsia in a previous pregnancy, or body mass index ≥35. It was hypothesized that high dose (4.0 mg per day) supplementation starting in early pregnancy and continued throughout the entire pregnancy will lower the incidence of preeclampsia in pregnant women at high risk of developing preeclampsia.
Telbivudine reduces DNA and normalizes alanine aminotransferase levels (ALT) in chronic hepatitis B patients with few adverse effects, but its use during pregnancy has not been explored. In this open-label, prospective study from the second trimester to post-partum week 28. This trial is to study the efficacy, safety and tolerability of Telbivudine in HBeAg Positive Chronic Hepatitis B Pregnant Women with high level of serum HBV DNA and elevated alanine aminotransferase levels.
Studies have demonstrated a relationship between subclinical hypothyroidism and obstetrics complications like preterm delivery, pre-eclampsia, placental abruption and stillbirth. Subclinical hypothyroidism and positive thyroperoxidase antibodies (TPOab) may increase the risk of early spontaneous abortion before 12 weeks of gestation. But there is not a consensus if the prevalence of TPOab should be treated before and during pregnancy when the level of thyroid-stimulating hormone (TSH) is normal. Thyroid hormones are regulators of the mitochondrial activity and our research group has previously shown that subclinical hypothyroidism affects mitochondrial activity. The hypothesis: Subclinical hypothyroidism causes early spontaneous abortion and or complications in pregnancy like pre-eclampsia because of mitochondrial dysfunction
Forty percent of pregnant women in the United States are women who have never given birth. As a group, they sometimes have complications with their pregnancy, but there is no information from a previous pregnancy to identify who might have a problem. Very little research has been done with this group. The Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be (nuMoM2b) is collecting data from a diverse population of about 10,000 women who are having their first baby and are carrying only one baby. The women are enrolled early in pregnancy and undergo research assessments four times during their pregnancies. Data are collected through interviews, self-completed data forms, clinical measurements, ultrasound, and collection and storage of blood samples, urine samples, and fluid from the vagina and cervix. Some information comes from medical records. A subset of women may be asked to participate in substudies collecting information on sleep breathing, sleep patterns and quality, or other areas possibly related to birth outcomes. The goal of the research is to find ways to identify women in this group who might develop a problem with their pregnancy and use this information to improve the health of pregnant women and their babies in the future. The study is focusing on pregnancy problems like high blood pressure, babies that are born much too early and very small babies.
Obesity is on the rise in all developed countries. Of particular concern is that more young people including children are being recognised as being overweight or obese. We know from a recent large national enquiry into all maternal and child deaths in the UK, known as CEMACH, that obesity is a major risk both for the mother and her child. When all deaths in women during pregnancy are analysed, obesity comes out as the most common risk factor. Babies of obese mothers are more than 3 times as likely to need admission to the Neonatal Intensive Care Unit. Traditionally, obesity is treated by lifestyle measures encouraging healthy eating and increasing physical activity. Unfortunately these measures are often insufficient to produce significant improvements in weight. If obese women gain little or even no weight during pregnancy, the outcome of the pregnancy is known to be improved. This was shown in a very large study of more than 120, 000 obese women. The drug metformin has been used for years in the treatment of diabetes and more recently for polycystic ovary syndrome (PCOS). Studies in pregnant PCOS women and women with diabetes in pregnancy have shown it to be safe and effective. Fortunately it is relatively cheap and taken as a tablet with meals. Metformin has the great advantage of not causing weight gain and often leads to a small amount of weight loss. It works by improving the body's sensitivity to insulin which is important as resistance to insulin is common in obesity. We have a lot of experience using metformin to treat women with diabetes in pregnancy where it is greatly beneficial. We now wish to examine its potential for obese women who do not have diabetes. We are hoping to show that it will benefit these women by causing less weight gain, less high blood pressure, and less diabetes. We anticipate babies will also have better birth weights, will be easier to deliver naturally, will not need to go to special care baby units and will be healthier.
The study is a multicenter randomized double blind placebo controlled trial. The study will be conducted on pregnant women with a diagnosis of intrahepatic cholestasis of pregnancy (ICP) in third level hospitals (that are also Academic Hospitals). Pregnant women at the time of ICP diagnosis will be randomized in two groups: Group 1 - will receive placebo and obstetrical monitoring until delivery Group 2 - will receive UDCA at the dose of 20 mg/Kg/day and obstetrical monitoring until delivery. The hypotheses are that UDCA treatment will be superior to placebo and effective in: reducing the rate of prematurity; improving maternal biochemical parameters and symptoms.
We hope to clarify how betamethasone affects glucose levels in the mother in the days after receiving the drug. This understanding will hopefully allow us to better anticipate the risk of maternal hyperglycemia and therefore establish more appropriate monitoring of maternal glucose to prevent maternal and neonatal complications of hyperglycemia.
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).
