Filter by:Fetal cells are not easily obtained from pregnant patients; this curtails testing to assess the health of the fetus and the mother. Currently, the only way of diagnosing fetal genetic or chromosomal abnormalities is by invasive techniques, such as chorionic villous sampling (CVS) and amniocentesis performed at 10 to 13 weeks and after 15 weeks of gestation, respectively. Although small, there is a risk for fetal loss with these procedures. Transcervical cell sampling (TCS), similar to a Pap smear, is a platform that meets the requirements for prenatal genetic testing (genetic testing with fetal cells obtained before birth), as well as diagnosis of maternal pregnancy complication, at a very early stage of pregnancy (as early as 5 weeks) and carries low risk for the mother and the developing fetus. This study will examine cervical fluid collected using various noninvasive methods for TCS in pregnant women. The number of placental cells will be assessed against similarly obtained samples from nonpregnant women of reproductive age who lack cells derived from a placenta. Participating volunteers will provide written informed consent. Only standard medical procedures and approved devices will be used for collection of cervical fluid, minimizing risk to the participants and their fetuses. No test results or other benefits will be available to the participants.
The main objective is to assess whether there are factors associated with women's refusal to participate in a randomized clinical trial involving first-trimester screening for pre-eclampsia. The secondary objective is to qualitatively evaluate the reasons for acceptance and refusal to participate.
The goal of this study is to learn whether access to healthy and fresh food, health coaching, and nutrition support intervention can reduce adverse birth outcomes in pregnant women. The main questions it aims to answer are: - Does access to healthy and fresh food, health coaching and nutrition support reduce the risk of gestational diabetes or preeclampsia and ultimately improve health outcomes for mothers and their newborns? - Are participants able to successfully utilize the health program? Are participants satisfied and self-equipped to apply the teachings of the program within their lives following their participation in the study? Participants will be randomly assigned to one of two groups. Participants in the standard of care will be asked to: - Complete surveys - Biometric screenings Participants in the intervention group will be asked to: - Complete surveys - Biometric screenings - Participate in weekly personal health coaching - Receive and consume provided weekly meals. Researchers will compare the standard of care to those who receive the intervention to see the impact of the intervention on clinical outcomes including: gestational weight gain, blood pressure, diagnosis of gestational diabetes, diagnosis of gestational hypertension or preeclampsia, and gestational age at birth.
The purpose of this study is to compare the effects of aerobic (AE), resistance (RE), and combination (AERE) exercise throughout pregnancy on selected maternal and fetal/neonatal physiological variables in women at-risk for preeclampsia. The central hypothesis of this project is that exercise will decrease severity and occurrence of preeclampsia symptoms, thus improving maternal, pregnancy, and birth outcomes. Aim 1. Determine the influence of different exercise modes during pregnancy at risk of preeclampsia on maternal cardiometabolic health. Aim 2. Determine the most effective exercise mode in pregnancy at risk of preeclampsia on improving birth and infant health outcomes.
Preeclampsia (PE) is a very frequent obstetric complication. C1q, the first recognition molecule of the classical pathway of complement system (C), represents a double-edged molecule in determining pregnancy outcomes. In animal models, C1q deficiency caused the development of a dysfunctional placenta and PE-like symptoms. Conversely, lower levels of C components were detected in the sera of patients with PE due to C consumption and increased deposition of activated C components in the placenta, as well as to the binding to placental apoptotic bodies, syncytiotrophoblast microvesicles (STBM) and debris which are increased in the circulation of patients with PE. C1q is a hexameric glycoprotein of 460kDa composed by six copies of three polypeptide chains A, B and C, each made by a C-terminal globular head (gC1q) and a N-terminal collagen-like region (CLR). This molecule can be the target of an antibody response. Autoantibodies targeting C1q were first recognized in the serum of Systemic Lupus Erythematosus (SLE) patients. The presence of anti-C1q autoantibodies was also detected in patient affected by autoimmune disease (ie, kidney disorders, vasculitis, thyroiditis). Almost all of these autoimmune disorders are associated with an increased risk of developing PE during pregnancy. Anti-C1q detection mainly concerns the prediction of the onset of lupus nephritis (LN) in SLE patients. Although anti-C1q autoantibodies do not deplete circulating C1q, their presence in maternal circulation and in placenta may trigger improper C activation and impair C1q activity. In pregnancies complicated by autoimmune affection such as SLE, autoimmune thyroid disorders and Antiphospholipid syndrome (APS) the prevalence of anti-C1q appeared to be higher than in control pregnancies and associated with miscarriage. High levels of anti-C1q have been found in a group of Japanese patients suffering recurrent pregnancy loss (RPL). In a group of anti-C1q positive healthy pregnancies and LN patients was assessed whether C1q autoantigenic behaviour could vary among individuals with or without correlated manifestation. Sera from healthy pregnancies and LN patients were screened for the presence of autoantibodies against the CLR fragment and/or the gC1q: antibodies against gC1q were found in both groups, whereas anti-CLR were only detected in the LN one, suggesting that only the latter may have a pathogenic role. Despite this, the biological functions of anti-C1q remain far from clear
Stress and Sleep of Classical Turkish Music in Pregnant Women Diagnosed with Preeclampsia in Clinics The study to be carried out to determine the effect on quality is a randomized controlled experimental research. All patients who comply with the limitations of the study and volunteer will be included in the study. When the studies in the literature are examined, there are a limited number of studies on the effects of music on pregnant women diagnosed with preeclampsia, and no studies have been found on the effects of music on stress and sleep quality in pregnant women with preeclampsia. This research aimed to determine the effect of Classical Turkish Music on stress and sleep quality in pregnant women diagnosed with Preeclampsia in clinics.
Previous studies demonstrated that Placental Growth Factor (PIGF) and Vascular Endothelial Growth Factor (VEGF) produced by trophoblast cells decreases during Preeclampsia, whereas soluble fms-like tyrosine kinase-1 (sFlt-1), an antiangiogenic factor, increases. The ratio sFlt-1/PlGF has a higher positive predictive value than the isolated measurement. A ratio under 38 exclude risk of imminent preeclampsia and allows to outpatient follow-up with a negative predictive value of 99.3%. A ratio equal or higher than 38 permits to direct high-risk patients towards hospitalization with a positive predictive value of 36.7% of preeclampsia at 4 weeks. These findings suggest that the ratio can be used to select more appropriately women needing hospitalization for suspected preeclampsia.
This is a prospective, single-center, randomized control study to determine if video education at the time of postpartum discharge improves patient knowledge on the warning signs for the top three causes of severe maternal morbidity (infection, hemorrhage, and blood pressure disorders) in the first seven days following delivery for self-identified, Black, Latinx, other with two or more self-identified races, Medicaid, and/or uninsured postpartum individuals. Participants will be randomized to written discharge education + video education (intervention) vs standard discharge education (control). They will complete a baseline questionnaire and a post-discharge education questionnaire during their postpartum stay to assess for knowledge improvement. The investigators hypothesize that video education will improve patient's knowledge of severe maternal morbidity warning signs.
The objective of this research project is to conduct a single-site pilot trial to assess the feasibility and effect of low-dose aspirin to augment vascular recovery in the immediate postpartum period after preeclampsia through two specific aims: 1) to pilot test the feasibility of conducting a randomized controlled trial of postpartum low dose aspirin vs. placebo, and 2) to assess the effect of postpartum aspirin on endothelial function and blood pressure. Our central hypothesis is that postpartum administration of low-dose aspirin following preeclampsia will be feasible, improve endothelial function, and lower BP at 6 months postpartum. Subjects will undergo 3 study visits involving BP measurements, blood draws, questionnaires, and/or microiontophoresis. Up to 60 adult subjects will be enrolled at Magee-Women's Hospital.
The goal is to demonstrate the relationship of the circulating pool of T-regulatory lymphocytes in the mother's peripheral blood with populations in the placentas and to compare with controls, what is the difference in the expression of individual regulatory molecules of T-regulatory lymphocytes according to new paradigms. The proportional and functional characteristics of T-regulatory lymphocytes will be correlated with the composition of the intestinal and vaginal microbiota.
