Filter by:This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin in youths with obesity, ages 12-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (3 sprays per nostril, 4 times per day) for 12 weeks. Study visits include screening to determine eligibility, 2-part main study visits at baseline, week 8, and week 12, and safety check-in visits at weeks 1, and 4; phone calls at weeks 2, 6, and 10, with a safety follow-up visit 6 weeks after the last dose of study drug. Study procedures include appetite, behavioral, metabolic, and endocrine assessments.
The purpose of this study is to specifically investigate whether oxytocin and mechanical dilation decreases the rate of cesarean section compared to misoprostol and mechanical dilation for pregnancies at risk of fetal compromise
Aim: This study has been planned as an observational study. The aim of this study is to determine the effect of labor induction with oxytocin on early postpartum hemorrhage, perineal integrity and breastfeeding. Materials and Methods: The sample consists of 88 healthy mother and infant pairs. The mothers in the case group will receive oxytocin induction before and after delivery. On the other hand, the mothers in the control group will not receive any oxytocin induction before delivery, and will receive oxytocin induction in the end of delivery. Data were collected by using the Personal Information Form, the LATCH Breastfeeding Diagnostic Scale, the Breastfeeding Self-Efficacy Scale, the follow-up bag for postpartum hemorrhage, and episiotomy healing assessment known as the REEDA Scale.
The study aims to examine a behavioral and neural framework for understanding the sex-specific effects of the neuropeptide oxytocin (OXT). Using hormonal, behavioral and neuroimaging readouts, it is planned to explore the interplay of OXT and estradiol as a potential mechanism mediating sexual dimorphic effects.
The study examines the (sub)regional specificity of anxiolytic oxytocin (OXT) effects on emotional face processing and reactive and cognitive fear. Preliminary data indicate that the Receptor for Advanced Glycation End Products (RAGE) may regulate oxytocin transport into the brain. Thus, the study aims to replicate previous observations of oxytocin effects on the processing of fearful faces in the centro-medial amygdala and to assess whether a RAGE polymorphism (-374 T/A: rs1800624; TT vs. TA/AA), that has been shown to alter transcriptional activity, modulates anxiolytic OXT effects.
This project will study the effect of oxytocin on hemodynamics in patients undergoing laparoscopic myomectomy, and how to prevent and manage such hemodynamic changes effectively.It provides a reference for the rational use of oxytocin in clinical practice, which can not only effectively contract the uterus and reduce bleeding, but also reduce the influence on hemodynamics.
This study evaluates the need of oxytocin therapy in active phase of labor. there will be two groups treating with oxytocin in latent phase.One group will be treated with low dose oxytocin therapy and the other group will be treated with high dose oxytocin therapy. oxytocin treatment will be ceased at the beginning of the active phase of labor. the need of oxytocin treatment in active phase of labor will be compared between two groups.
Previous research has indicated that direct eye gaze compared to averted gaze, elicits a higher skin conductance response (SCR), and a more pronounced left frontal cortex activity than right frontal cortex activity (resulting in positive asymmetry scores). On a behavioral level, participants tend to look shorter at live faces with a direct gaze as compared to averted gaze (Akechi et al., 2013). Further, subjective evaluations showed that a direct gaze is rated more arousing and less pleasant than an averted gaze (Akechi et al., 2013; Hietanen, Leppänen, Peltola, Linna-aho, & Ruuhiala, 2008). Importantly, oxytocin administration increases the number of fixations and to looking time towards the eye region during live social interaction. Further, oxytocin has been shown to influence SCR and heart rate variability. Therefore, it is conceivable that oxytocin will not only influence the gaze duration of the participant, but also the physiological and neurological responses elicited by direct eye gaze. In this study, the investigators will investigate whether oxytocin modulates the behavioural (eye gaze and subjective ratings), neurological (EEG) and physiological (skin conductance, heart rate and respiration) responses elicited by direct gaze.
In this study, the investigators will explore the influence of oxytocin administration on several neurophysiological responses (EEG, skin conductance and heart rate) during rest.
This study will aid in the development of a research instrument for rapid and highly sensitive detection of perinatal salivary oxytocin, by non-invasive means. There will be two study cohorts: Induction of labor cohort (20) and Cesarean delivery cohort (5) for a total of 25 participants.The standard clinical protocols for administering oxytocin to human subjects at Lucile Packard Children's Hospital will be followed. Oxytocin will be prescribed and dosed as per standard of care with no change due to study enrollment. The study will only involve sampling of saliva and blood. The general hypothesis to be tested is that 1) the sensor will accurately report the levels of oxytocin in saliva samples as compared with standard reference methods and 2) the sensor yields rapid (<20 minutes) oxytocin results with minimal discomfort to subjects. Overall, this will allow to optimize the administration of oxytocin, and for a better understanding of the blood concentration and effects of oxytocin on mother and child.
