NCT ID: NCT05492708 Recruiting - Pregnancy Related Clinical Trials

The Heartland Study

Start date: January 11, 2020
Phase:
Study type: Observational

The Heartland Study is a prospective, observational study that will enroll up to 2,600 pregnant participants across the Heartland States in the U.S.. The objective of the Heartland Study is to address major knowledge gaps concerning the health effects of herbicides on maternal and infant health. The study is being conducted to evaluate the associations between environmental exposures to herbicides during and after pregnancy and reproductive health outcomes. The study is measuring multiple biomarkers of herbicide exposure among pregnant Midwesterners and their partners to evaluate associations with pregnancy and childbirth outcomes, epigenetic biomarkers of exposure, and child development.

NCT ID: NCT04705324 Recruiting - Clinical trials for Intrauterine Adhesion

Dilation and Curettage Versus Operative Hysteroscopy for Missed Abortion

Start date: January 21, 2022
Phase: N/A
Study type: Interventional

Randomizedtrial comparing success and complication rates of operative hysteroscopy versus traditional dilation and curettage (D&C) in the management of first trimester missed abortion.

NCT ID: NCT04456660 Recruiting - Clinical trials for Spontaneous Abortion

Comprehensive Assessment of Risks for Miscarriage.

MIS-CARE
Start date: June 20, 2020
Phase:
Study type: Observational

This study aims to determine the role of serum biomarkers and placental bloodflow in the comprehensive evaluation of the risk for spontaneous abortion

NCT ID: NCT04182503 Recruiting - Preterm Birth Clinical Trials

Environmental Factors and Embryonic Development Project

EFED
Start date: August 12, 2019
Phase:
Study type: Observational

The Environmental Factors and Embryonic Development Project was set up to investigate environmental exposures and behavioral factors responsible for embryonic dysplasia and gestational complications in pregnant women.

NCT ID: NCT04003064 Recruiting - Oxidative Stress Clinical Trials

Heavy Metals' Influence on Early Pregnancy Through Oxidative Stress

Start date: May 20, 2019
Phase:
Study type: Observational [Patient Registry]

Patients with diagnosis of spontaneous abortion are enrolled in the cohort, in the cohort of patients who met the criteria, 3ml of whole blood intravenous and 5ml of urine were taken for heavy metal level examnation. Part of the villi tissue was sent for genetic testing, and the results were traced. In addition, about 10g of villi tissue was frozen for testing. Patients with normal genetic results of villi tissue will have villus samples go through oxidative stress level detection.

NCT ID: NCT03332706 Recruiting - Clinical trials for Spontaneous Abortion

the Association Between Blood's and Urinary Heavy Metal Level in Pregnant Women and the Spontaneous Abortion

HMLandSA
Start date: October 10, 2017
Phase: N/A
Study type: Observational

The aim of the study was to define the possible association between heavy iron level and the consequence of pregnancy especially spontaneous abortion and missed abortion. The study population will comprised the first-trimester pregnant women in the PUMCH (Peking Union Medicine College Hospital) during 2017 October to 2018 November. We categorised the patients into two groups, the study group where the patients suffered from spontaneous abortion or missed abortion, and the control group where the patients carry the normal live fetal for at least 8 weeks and ask for artificial abortion. All the cases included in the study were examined with respect to 6 kinds of heavy iron level in venous blood and urine, then correlation analysis was applied to define heavy iron level between two groups.
