NCT ID: NCT04215484 Completed - Placenta Accreta Clinical Trials

Placenta Accreta New Detection Procedure by Rapid Assessment of Serum BNP

PANDORA
Start date: January 2, 2020
Phase:
Study type: Observational [Patient Registry]

The placenta accreta is defined as a placenta that is abnormally adherent to the myometrium. It can thus invade the entire thickness of the myometrium (placenta increta) or even exceed the serosa and invade neighboring organs (placenta percreta). It is a rare obstetric pathology with significant morbidity, and its management most often requires hemostatic hysterectomy. Its frequency has increased significantly in recent decades due to the increased rate of caesareans. The maternity center of Tunis ( CMNT ) is a level 3 maternity center, supporting over 12 000 births yearly, where the caesarean section's rate is very high, close to 45% of deliveries. Recently we noted an increase in abnormal placental invasion incidence : in 2018, we report over 60 cases of placenta accreta,increta and percreta. Early detection of these patients can help reduce potential risks. Ultrasound and MRI are the main diagnostic tools, but each one has weaknesses. Biological approch of this diagnosis is not well studied. Recently, BNP has been shown to be associated with increased angiogenesis. Because placenta accreta is characterized by abnormal uteroplacental neovascularization, it has been hypothesized that serum BNP levels may be related to abnormal invasion of the placenta. In the literature, only one study investigated the relationship between cardiac biomarkers (Pro-BNP, CK, CK-MB and troponins) and abnormalities of placental adhesion. The main conclusion was that the Pro-BNP could predict placental accretisation. Thus, the BNP as a mean of screening, could enrich our diagnostic arsenal. The purpose of our study is to determine whether or not BNP can predict abnormal placental invasion during pregnany.

NCT ID: NCT03692923 Completed - Normal Pregnancy Clinical Trials

VIRTUAL COMMUNITY for PREGNANT WOMEN

Start date: May 1, 2012
Phase: N/A
Study type: Interventional

The study aimed to investigate the effect of exclusive peer-to-peer virtual support on pregnant women's well-being including physical symptoms, depression, social support, maternal attachment, and pregnancy adaptation.

NCT ID: NCT01907620 Completed - Normal Pregnancy Clinical Trials

Circulating Oxidative Stress and Gestational Hypertension. Study of the Evolution of Free-radical Markers of Oxidative Stress From Before to After Childbirth in Two Groups of Women: Normal Pregnancy and Pre-eclampsia.

Start date: November 2010
Phase: N/A
Study type: Interventional

The aim of this study is to explore a mechanism that could potentially explain why women with a pregnancy complicated by pre-eclampsia are described as having an increased risk of cardiovascular disease later in life. If the hypothesis of this study turns out to be true, that is to say that women with pre-eclampsia have a higher level of oxidative stress than women with a normal pregnancy and that this difference persists after the delivery (6 months), a controlled randomized interventional study aiming to evaluate either therapeutic supplementation with antioxidant vitamins (Vit C and E) or modifications in diet could be envisaged.

NCT ID: NCT00437996 Completed - Normal Pregnancy Clinical Trials

Comparative Affect of a Continuous Epidural Infusion of Clonidine During Labour. Prospective Double Blind Randomized Trial

Start date: February 2007
Phase: Phase 3
Study type: Interventional

Addition of clonidine to an epidural mixture of local anaesthetic and morphine improves analgesia and reduces the frequency of motor blockade during epidural analgesia. several side effects are possible mostly somnolence and hypotension. Association of continuous clonidine infusion with low concentrations of levobupivacaïne and sufentanil was not studied during labour. The objective of this study is to compare the effectiveness and the side effects of a PCEA with levobupivacaïne 0,0625 % and sufentanil 0.25 microg.ml-1, without addition of clonidine, and with addition of clonidine at a concentrations of 2 microg.ml-1.

NCT ID: NCT00341263 Completed - Normal Pregnancy Clinical Trials

Maternal and Umbilical Cord Hormone Concentrations in Twin and Singleton Pregnancies

Start date: November 21, 2003
Phase:
Study type: Observational

This study will examine levels of hormones, such as estrogen and testosterone, in maternal and umbilical cord blood to compare hormones between mothers who are having twins and mothers who are having one baby. It will investigate whether hormone levels in twin versus singleton pregnancies influence the babies' risk of developing breast, prostate, and testicular cancers later in life. Pregnant women 18 years of age and older who do not have preeclampsia, chronic hypertension, pre-pregnancy or gestational diabetes, thyroid disease, or other major pregnancy complications are eligible for this study. Participants will be recruited from the obstetrics and gynecology practice at the Dartmouth Hitchcock Medical Center in Lebanon, New Hampshire. Participants will have a blood sample drawn from their arm during their third trimester prenatal visit and again when they are admitted to the hospital for delivery. After the baby is born, a blood sample will be collected from the cut umbilical cord. Information about the pregnancy and delivery will be collected from the mother's medical chart, and information about the baby's size will be obtained from the baby's medical chart.
