Filter by:The specific goal of the proposed research is to develop a reliable, non-invasive fetal and maternal heart rate and contraction monitor that is unaffected by obesity and requires less nursing intervention than the tocodynamometer and Doppler ultrasound.
This measurement study was designed to evaluate the performance of SureCALL® Labor Monitor® (SureCALL®) compared to the predicate Tocodynamometer device (TOCO) in preterm and term pregnant patients.
The project aims to clarify the effect of the thromboprophylactic LMWH dose on coagulation in pregnant women just before birth, at the period of maximal physiological hypercoagulable state and with high risk of thromboembolism, the most common cause of maternal mortality in developed countries. Although LMWH are now routinely administered as prevention of thromboembolism, their effect on coagulation in pregnant women was not yet studied. The doses of LMWH in pregnancy are only derived in terms of coagulation from totally different groups of patients (surgical, orthopedic). We therefore will map the effect of thromboprophylactic LMWH dose on coagulation in pregnant women using recently available methods, especially a complex examination of coagulation within 24 h after LMWH application using thrombelastography, including examination with heparinase, and monitoring the effect of LMWH by measuring antiXa and TGT (thrombin generation time) activity. Based on these results we will also evaluate the possible influence of LMWH prophylaxis on the risk of spinal haematoma during neuraxial analgesia/anesthesia for delivery/Caesarean section. On the basis of our pilot results we can presume the current dosage of LMWH in pregnant women is inadequate and that it would be appropriate to adjust presently used dosage. At the same time we want to prove that the standard LMWH thromboprophylaxis in pregnant women does not increase the risk of spinal haematoma during neuraxial blockade. In both situations the targeted outcome is to increase the safety of pregnant women.
This is a study for the evaluation of the benefits of 1 st Trimester risk markers in detecting Early Onset Pre-eclampsia and the use of the Placental Growth factor(PIGF) as a potential marker for Trisomy 21 and other aneuploidies. Aim of this prospective nonprofit study is to analyze the benefits of early onset pre eclampsia risk assessment in the 1st trimester (measuring biochemical markers [PIGF], blood pressure and Doppler ultrasound), and how the results can permit to modify or influence the course of the preeclampsia during the pregnancy. The investigators will also evaluate the potential use of the PIGF as a marker to improve the prenatal screening with the currently used nuchal translucency, serum Pregnancy-associated plasma protein A (PAPP-A) and free beta subunit of human chorionic gonadotropin (fBhCG) parameters.
The purpose of this Stage II clinical trial is to test the efficacy of a culturally sensitive, cognitive-behavioral intervention to reduce sexual risk behavior among minority adolescents for prevention of sexually transmitted infection (STI/HIV), unintended pregnancy and abuse by changing high-risk sexual behaviors, decreasing substance use and encouraging contraceptive use. Its primary goal is to expand risk-reduction interventions created in previous studies to further increase intervention efficacy for this particularly vulnerable, high-risk group. An adolescent intervention has been created and pilot tested in developmental studies. Results indicated reductions in substance use, risk behaviors, unintended pregnancy, STI and abuse without reports of adverse outcomes. Specific aims of the current study include: 1) To obtain a more in-depth understanding of configurations of psychosocial and situational factors associated with high-risk sexual behavior, substance use, STI/HIV and contraceptive use among abused minority adolescent women with STI; 2) To implement a controlled randomized trial of a cognitive behavioral risk-reduction intervention consisting of 2 small group sessions, 2 individual counseling and 3 support groups for this group; 3) To evaluate the effects of the adolescent intervention model versus enhanced counseling for this group on AIDS Risk Reduction Model (ARRM)-related constructs, high-risk sexual behavior, substance use, abuse recurrence, contraceptive use, unintended pregnancy and STI/HIV at 6 and 12 months follow-up. Participants will include a convenience sample of 600 Mexican-and African American adolescent women, aged 14-18 years with a history of sexual or physical abuse and current STI.
Introduction: Preterm labor (PTL) is an important obstetric intercurrence that affects 5 to 10% of pregnancies. Among the known factors of PTL etiology are PTL occurrence in previous pregnancies, multiple pregnancies, polyhydramnios, vaginal bleeding during pregnancy, premature membrane rupture (PMR) and bacterial vaginosis. Despite the advancement achieved in Neonatology, morbidity and mortality resulting from high rates of preterm births have remained constant in the last few decades. Objective: This study aims at evaluating maternal and perinatal outcomes of pregnant women with a history of preterm labor in previous pregnancies and submitted to active search for vaginal infection. Material and Method: It is a prospective-cohort epidemiological study to be conducted in Botucatu/SP. Two study groups (G1 and G2) will be formed, and each of them will comprise 140 pregnant women with a history of preterm childbirth. G1 will be related to the active search and etiological diagnosis of lower genital tract infections, and G2 will be related to non-search for such infections, for which the routine care protocol of primary health units in the city of Botucatu will be maintained. Care propedeutics for the pregnant women (G1) will include the performance of direct examination of vaginal content stained by the Gram method, culture in Diamonds medium, polymerase chain reaction (PCR) of endocervical secretion collected in the primary health care services in the city at two moments: prior to the 20th gestational week (M1) and at the 36th week (M2). Moment M3 will take place after childbirth for evaluation of the perinatal outcome.
Magnesium sulphate is the first line therapy for the management of preeclampsia and eclampsia in obstetrics. Perioperative administration of magnesium sulphate has been proved to be an effective as an analgesic adjuvant. The investigators evaluated the analgesic effect of magnesium in parturients undergoing Cesarean section.
This is an observational study in which patients who have been prescribed Néevo®/NéevoDHA® are invited to participate in surveys about their pregnancy and experiences with Néevo®/NéevoDHA®. The purpose of this study is to increase the understanding of the role of L-methylfolate among patients who are candidates for Néevo®/NéevoDHA®, provide patients with personalized education and support during their pregnancies, and contribute to the overall understanding of the needs and concerns of women facing intermediate- to high-risk pregnancies.
Preeclampsia is associated with significant maternal and fetal morbidity and mortality. Early identification and subsequent management of patients at risk of developing preeclampsia presents an ongoing challenge in prenatal care. Some at risk pregnancies may be identified from: - serum screening abnormalities in the first or second trimester - placental shape and texture at the 18-20 anatomical ultrasound - uterine artery blood flow. Early identification and effective treatment of patients would permit the safe completion of the pregnancy for the mother and infant. Recent advances in non-invasive cardiovascular monitoring have enabled the study of maternal hemodynamics in normal and at-risk pregnancies. This study hopes to identify the earliest significant changes in maternal hemodynamics which may allow targeted therapeutic interventions in patients at high risk of developing preeclampsia. The hypothesis of this study is that systemic vascular resistance rises during the pre-clinical phase of preeclampsia and this can be captured using non invasive bioreactance technology. Treatment of the abnormally high vascular tone may decrease the severity and postpone the onset of clinical disease.
Background: The health of the next generation is likely programmed in the womb (i.e.in utero), and our understanding of how that programming happens will allow us to favorably influence the health of future generations. The focus of this proposal is to examine the effect of in utero programming on heart function in children born to women with type 2 diabetes (T2DM). Specifically, neonates born to diabetic women have abnormal heart structure and weaker heart function at birth, which may predispose them to long-term heart problems in childhood, adolescence and adulthood. At present, the reason for these heart abnormalities in children born to women with diabetes is unknown and is the focus of this proposal. Objective(s) and Hypothesis(es): The objectives are to examine the relationships among maternal lipid (fatty acid, triglyceride, very low density lipoprotein) metabolism and neonatal heart structure and function in diabetes and to identify clinical markers during pregnancy for heart dysfunction in infants born to diabetic women. The overall hypothesis is that maternal lipid metabolism is abnormal in diabetes, and this metabolic dysregulation increases fatty acid delivery to the fetus in utero and leads to abnormal accumulation of lipid in the fetal heart, resulting in altered neonatal heart structure and function in infants born to diabetic women. In addition, the investigators hypothesize that decreased maternal fatty acid oxidation (fat "burning") rate, elevated lipolytic (fat breakdown) rate and elevated blood total free fatty acid level predicts abnormal neonatal heart structure and function in infants born to women with type 2 diabetes. Methods and Procedures: The investigators will test these hypotheses by using clinical metabolism studies (infusion of stable isotope labeled fatty acid, serial blood and breath sampling, and mass spectrometry) to quantify whole-body fat (fatty acid oxidation, lipolysis, and serum fatty acid , triglycerides, VLDL-cholesterol levels) metabolism in 25 diabetic women during the 3rd trimester of pregnancy, and compare these lipid metabolism kinetics to 25 body mass index matched healthy non-diabetic women during pregnancy and determine if alterations in maternal lipid metabolism predict abnormal neonatal heart function in children born to these women. Potential Impact: Type 2 diabetes is an epidemic in the United States and is steadily increasing worldwide. Diabetes has detrimental health effects in pregnant women and in their offspring. The investigators know that children born to women with diabetes have an increased risk for developing diabetes, obesity and cardiovascular disease, than children born to healthy women. This proposal will address an important knowledge gap regarding the role of maternal lipid (and potentially other nutrients) metabolism on the cardiovascular health of the global and increasing population of children born to diabetic women. Findings from this project will be novel and innovative, and will likely point to clinical interventions that target and correct lipid and other metabolic abnormalities in women with pre-gestational diabetes. The impact will be great because the long-term goal is to ameliorate heart problems in children born to diabetic (both pre-gestational and gestational) women. In addition, this project will establish a small cohort of children that can be followed long-term to address novel questions about the progression of heart and other metabolic abnormalities in children born to diabetic women.
