Filter by:Parturients receiving spinal anesthetic for Cesarean section will be randomized to have/not have pre-spinal ultrasound examination of their back.
This study wants to investigate if ultrasound assisted epidural catheter insertion for labor analgesia is easier and safer to the standard epidural technique.
There is a gap in knowledge regarding the effects of Vitamin D supplementation on periodontal status in pregnant wome. The investigators aim to evaluate the potential benefit, if any of vitamin D supplementation during pregnancy on periodontal disease and relevant outcomes including burden of infections and prematurity rates. the investigators hypothesize that 1. Vitamin D supplementation during pregnancy improves the periodontal health. 2. There is an association between inflammatory biomarkers and periodontal health of pregnant females. 3. Vitamin D supplementation improves the outcomes of pregnancy such as prematurity rates and birth weight
The investigators hypothesize that given prophylactically, intravenous ondansetron will attenuate the drop in blood pressure and heart rate frequently seen after spinal anesthesia. Eighty-six American Society of Anesthesiologists (ASA) physical status I or II in preoperative patient assessment, parturients age of 18 to 45 years scheduled to undergo elective caesarean section will be enrolled. Patients will be randomized to 2 groups: the ondansetron group, receiving 8 mg intravenous ondansetron diluted in 10 mL of saline; or the placebo group, who were administered 10 mL of saline given 5 minutes prior to performing the spinal anesthetic. Investigational Pharmacy will randomize and dispense study drug. Baseline measurements of vital signs will be taken. Otherwise standard management will then be used: - Patients must be NPO for 8 hours - Pulse oximetry, EKG monitoring, noninvasive blood pressure at a minimum of every 3 minutes, more frequently if decided by the provider. - Standard lumbar puncture in a sitting position the L3-L4 or L4-L5 - Whitacre pencil-point, 25 gauge - Injectate: 2 mL of 0.75% hyperbaric bupivacaine, 100 mcg preservative free morphine, 20 mcg fentanyl - Immediately after completing the subarachnoid injection, patients will be laid supine with left lateral uterine displacement The sensory level of anesthesia will be assessed in the standard fashion every five minutes using ice. The motor component will tested using the Bromage scale for spinal anesthesia (0, no paralysis; 1, inability to lift the thigh [only knee/feet]; 2, inability to flex the knee [only feet]; 3, inability to move any joint in the legs).
This study is comparing the impact of two teen pregnancy prevention interventions, Reducing the Risk and Love Note with a non-related training on community building to determine which is most effective for which participants in delaying sexual initiation, enhancing use of condoms and other forms of birth control, decreasing sexually transmitted diseases and decreasing the number of pregnancies. The participants were 1450 youth between the ages of 14 and 19 including those from poor urban settings, those from immigrant and refugee families and those from the foster care system. Both girls and boys were be in the study. The investigators predict that girls, immigrants and refugees and foster youth will have better outcomes when participating in Love Notes, a program focused on healthy relationship formation and maintenance as a frame for how to manage the sexual aspect of relationships while boys and urban youth will have better outcomes when participating in Reducing the Risk. Both groups will have better outcomes than those in the control condition.
tPA has a pivotal role in placentation, mediationg activation of growth factors, such as vascular endothelial growth factor and brain-derived neurotrophic factor, degradation of extracellular matrix and basement membrane (directly or through activation of matrix metalloproteinases) and formation of hemidesmosomes. A high-carbohydrate intake combined with lack of physical activity provides a strong stimulus for maternal insulin production. In this scenario, either β-cells are dysfunctional and diabetes supervenes, or excessive amounts of insulin are produced, providing pathological stimulation of PAI-1 synthesis. Given that PAI-1 is a major tPA inhibitor, PAI-1 excess may affect placentation, increasing the risk of first trimester losses, preterm deliveries and intrauterine growth restriction. Our hypothesis was that prematurity was not the cause of neonatal hypoglycemia, but a parallel occurrence of a strong stimulus for maternal, fetal and neonatal production of insulin.
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 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.
