The purpose of this study is to test whether perioperative intravenous (IV) oxytocin compared to placebo results in faster recovery in disability as measured by daily steps over 56 days after Total Hip Arthroplasty (THA).

The goal of this clinical trial is to learn how 24 IU oxytocin (OT) and 24 IU arginine vasopressin (AVP), administered through the oral mucosa, affect attention to emotional faces and related brain activity in healthy adults. The study will compare OT and AVP with a placebo (PLC). The main questions it aims to answer are: 1. Does oromucosally administered oxytocin produce a behavioral pattern of modulation of top-down and bottom-up attention to emotional faces that is qualitatively consistent with previously reported intranasal oxytocin effects, and how does this pattern compare with that pr…

This study aims to investigate the modulation of intranasally administered oxytocin (24 IU) on human fairness perception and related prosocial behaviors.

Spinal anesthesia is the preferred anesthetic technique for cesarean section because of its advantages over epidural and general anesthesia. It is simple to perform, economical, provides rapid onset of anesthesia, and produces satisfactory muscle relaxation. However, spinal anesthesia may be associated with adverse effects, including nausea, vomiting, back pain, and post-dural puncture headache (PDPH)(1). PDPH is a well-recognized complication of dural puncture. It is typically characterized by a headache that is fronto-occipital in type after spinal anesthesia puncture which gets worse after…

Background: Carbetocin is an established single-dose uterotonic agent for postpartum hemorrhage prophylaxis at elective cesarean delivery. Despite its proven efficacy, many clinicians routinely add a supplemental oxytocin infusion following carbetocin administration without evidence-based justification. Concurrent oxytocin receptor stimulation may be redundant, counterproductive through receptor desensitization, or incrementally beneficial - a mechanistic uncertainty that remains unresolved in the published literature. Objectives: To determine whether carbetocin monotherapy (100 micrograms IV…

This study is testing whether oxytocin can help lessen pain by changing how people process emotions and social experiences. The goal is to better understand how the brain links emotions, relationships, and pain, and whether this connection can be used to improve pain treatment.

More than 15 million family caregivers provide support for individuals with Alzheimer's disease (AD) or related dementias. This number is expected to grow with the increasing population of persons with dementia (PWD). Stress in caregivers to older adults with chronic diseases is already a significant public health issue because it is associated with multiple negative physical and mental health outcomes for the caregiver (e.g., depression, cardiovascular disease) and can negatively impact the health of the PWD as well. Importantly, stress levels are even higher in female than male caregivers an…

An open-label, randomized, single-center, dose ascending trial will be conducted to evaluate the efficacy and safety of sublingual oxytocin for the prevention of post-partum hemorrhage caused by uterine atony in term pregnant women having an uncomplicated vaginal delivery.

The goal of this clinical trial is to learn if the drug carbetocin works better than standard care to prevent heavy bleeding after childbirth in people carrying twin pregnancies. Heavy bleeding after delivery, also called postpartum hemorrhage, is more common after twin births and can lead to anemia, blood transfusions, and other serious health problems. In this study, bleeding will be evaluated by measuring how much blood hemoglobin levels drop from before delivery to the day after delivery. The main questions this study aims to answer are: * Does giving carbetocin after delivery lower blo…

The primary aim of this study is to investigate whether intranasal oxytocin can modulate the real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback training effects by facilitating the use of an interoceptive strategy.

While Carbetocin is effective in reducing PPH, the combination of oxytocin, Tranexamic acid, and Ergot derivatives may offer additional benefits in high-risk populations. We hypothesize that the combination regimen will reduce PPH incidence and severity compared to Carbetocin alone and may be more cost effective

This study investigates how belief and expectation influence empathic pain-the pain we feel when observing others in distress. Healthy adult participants will be randomly assigned to one of three groups: no-treatment control, placebo nasal spray, oxytocin-containing nasal spray. Participants in both the placebo and oxytocin conditions will be informed that they are receiving oxytocin, described as a potent agent for pain relief. During functional MRI scanning, all participants will view naturalistic pain-related videos and provide ratings of perceived subjective pain. The study aims to examine…

This randomized controlled trial aims to evaluate the efficacy of adding preoperative rectal misoprostol to standard oxytocin for reducing intraoperative and postoperative blood loss in women undergoing elective cesarean section. Misoprostol is a prostaglandin E1 analogue that is inexpensive, heat-stable, and effective as a uterotonic agent. The study will compare outcomes between two groups: women receiving oxytocin alone and women receiving oxytocin plus rectal misoprostol. The primary outcome is the reduction of blood loss during and after surgery. Secondary outcomes include changes in hemo…

This is a randomized, double-blind, placebo-controlled crossover pilot study of single-dose intranasal oxytocin (6 IU and 24 IU) vs. placebo in adult men and women (aged 18 years and above) with arginine-vasopressin deficiency to evaluate the effect of oxytocin on anxiety, depression, and socioemotional functioning (Part A), with an optional randomized, double-blind, placebo-controlled 2-week repeated dose substudy of intranasal oxytocin 6 IU or placebo (Part B). Following a screening visit to determine eligibility, participants will return for three main study visits in Part A. During the ma…

The main aim of the present study is to investigate whether orally (lingual spray) administered oxytocin influences human top-down attention via oxytocin receptors and whether its effects are dose- and task-dependent.

This study is designed as a randomized controlled single-blind experimental study to examine the effectiveness of the oxytocin massage and Marmet technique applied to mothers who have undergone cesarean section on breast milk quantity and maternal state anxiety levels. The hypotheses of the study are as follows: H0.1. There is no difference in the amount of breast milk among mothers in the Marmet technique, oxytocin massage, and control (placebo) groups. H1.1. There is a difference in the amount of breast milk among mothers in the Marmet technique, oxytocin massage, and control (placebo) gro…

The study aims to investigate whether intranasal oxytocin (OXT) improves sexual well-being in patients with Arginine Vasopressin Deficiency (AVP-D). The trial consists of two parts: Part A assesses the effect of OXT on sexual well-being and intimacy over a 7-day treatment period in participants in a stable partnership. Part B assesses the effect of a single dose OXT on sexual arousal, fear and empathy in a clinical setting and is designed for single participants and those in partnerships.

The main aim of the present study is to investigate whether orally (lingual spray) administered oxytocin influences human social attention and behaviors via oxytocin receptors and whether its effects are dose- and task-dependent.

The goal of this clinical trial is to compare between higher and lower dose of oxytocin to induce delivery in obese women. Researches will compare between low and high doses of oxytocin. the study group will use high dose of oxytocin (20 units in 1000 ml) versus the control group which will use low dose of oxytocin (10 units of oxytocin in 1000 ml)

This study aims to investigate the potential beneficial effects of intranasal oxytocin compared to placebo on emotion recognition and acute psychosocial stress in patients with arginine vasopressin deficiency compared to matched healthy controls.

To determine the effectiveness of using two medications simultaneously versus one medication, as is standard of care, in preventing early postpartum hemorrhage. There have been studies that looked at giving two medications and that there were reduced odds of postpartum hemorrhage. Specific Aim 1: Determine if double simultaneous uterotonic agent regimen (misoprostol and oxytocin) is superior to single agent (oxytocin only) in reducing postpartum hemorrhage. Specific Aim 2: Determine any potential side effects of a double simultaneous uterotonic agentregimen (misoprostol and oxytocin) versus…

The investigators think that calcium carbonate can act as an assistive medication to improve contractions during labor.

Leveraging veterans' intimate relationships during treatment for posttraumatic stress disorder (PTSD) has the potential to concurrently improve PTSD symptoms and relationship quality. Brief Cognitive-Behavioral Conjoint Therapy (bCBCT) is a manualized treatment designed to simultaneously improve PTSD and relationship functioning for couples in which one partner has PTSD. Although efficacious in improving PTSD, the effects of CBCT on relationship satisfaction are small, especially among Veterans. Pharmacological augmentation of bCBCT with intranasal oxytocin, a neurohormone that influences mech…

The purpose of this study is to assess the effectiveness of prophylactic oxytocin on hemorrhage rates for second trimester dilation and evacuation (D\&E) in the clinic setting.

This study will investigate the effects of drugs called "uterotonics" that help with the contraction of the uterus after a baby is born. This uterine contraction is very important to stop the bleeding after delivery. An uncontracted uterine state is called "uterine atony", which can lead to an excessive amount of post-delivery bleeding. Carbetocin is an uterotonic drug that works well to prevent post-delivery bleeding. In some cases, carbetocin is not enough to contract the uterus, and ongoing bleeding continues. When that happens, there are other uterotonic medications that can be used. In th…

This is a randomized controlled trial investigating whether continuous oxytocin infusion in multiparous women shortens time to delivery, without altering maternal or neonatal outcomes, in augmented deliveries, compared to intermittent infusion.

Prolonged labor is usually managed with continuous oxytocin infusion. "Oxytocin rest" has been proposed as a strategy to resolve protracted labor in patients who have received continuous oxytocin without progress. This strategy involves discontinuing oxytocin then restarting infusion after a period of time, under the theory that washout of the oxytocin receptor will strengthen uterine contractions to improve labor progress. "Oxytocin rest" is performed on labor and delivery units across the United States. Yet, there is no randomized or prospective data to support the practice. The purpose of …

Oxytocin is a hypothalamic neuropeptide that is best known for its peripheral physiological effects in the female organism i.e., uterine contractions during birth. The neuropeptide furthermore affects reward processing and metabolic functions such as eating behavior and body weight. Oxytocin receptors are present in brain regions associated with the processing of rewards, e.g., ventral tegmental area (VTA), nucleus accumbens (NAcc) and nucleus stria terminalis. Previous studies indicate that oxytocin interacts with sex hormones such as estradiol in a sex-specific manner. Despite known sex dif…

Oxytocin has been proposed as a neuroendocrine mechanism that may mediate the relationship between dog ownership and positive health outcomes and be linked to human-dog interactions and is thought to be a mechanism of interspecies bonding. While the role of oxytocin in human bonding behaviours and social behaviour, in general, is becoming well-established the role of oxytocin in human-animal interaction and Animal-Assisted Interventions (AAI) remains unclear. This research gap calls for more high-quality research investigating this possible neuroendocrine underlying mechanism to advance knowle…

Background: Borderline personality disorder (BPD) is a frequentand serious psychiatric disorder characterized by a persistent pattern of instability in relationships, affect and self-image. Although long-term follow-up prospective studies have shown high clinical remission rates, they also point out that usually persist social functioning deficits, comorbidity, isolation, chronic affective clinic and life dissatisfaction. Self-compassion training (SCT) could be an effective strategy targeting self-criticism, shame and chronic feelings of worthlessness, as well as increasing resilience. In addi…

Some research suggests that administration of oxytocin with oxycodone may reduce its abuse liability and improve its ability to reduce pain. In a 6-session laboratory study, we will be evaluating the effects of oxycodone and oxytocin (combined and separately, across sessions) on experimentally-induced pain, subjective effects, and decision-making.

This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin on bone health in children with autism spectrum disorder, ages 6-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (30 IU, 2 times daily) for 12 months in the double-blind phase, followed by a 6-month open label phase during which all study subjects will receive intranasal oxytocin (30 IU, 2 times daily). Study visits include screening to determine eligibility, followed by study visits at baseline, week 2, and months 6, 12, 18 and phone calls every two weeks for …

The investigation team propose in this study to specifically evaluate the feasibility of using oxytocin in the form of an intranasal spray in a specific population of children with autism spectrum disorder and intellectual disability. The lack of studies centered on this population on the one hand, and on the other hand the severity of challenging behaviors presented by these children, make questionable the direct transfer of methods of care used in patients who do not present these challenging behavior. In this sense, the establishment of oxytocin treatment in these children requires a prelim…

Some research suggests that administration of oxytocin with oxycodone may reduce its abuse liability and improve its ability to reduce pain. In a 6-session laboratory study, the investigators will be evaluating the effects of oxycodone and oxytocin (combined and separately, across sessions) on experimentally-induced pain, subjective effects, decision-making, and activation of different neural substrates.

A randomized trial of patients undergoing a term (≥37 weeks) induction of labor with a history of one prior Cesarean delivery, wherein the provider intends to use a Foley catheter for cervical ripening. The investigators will be comparing Foley alone with concurrent Foley and Oxytocin use at the start of the induction. With this trial, the investigators aim to test our central hypothesis that concurrent Foley and Oxytocin will decrease time to delivery without increasing risks, compared to Foley alone.

Research on schizophrenia spectrum disorders (SSD) patients with social impairment is essential for improving treatment, enhancing the lives of affected individuals, reducing stigma, and advancing our understanding of this complex psychiatric disorder. A clinical trial focusing on the improvement of social skills in SSD has the potential to transform clinical practice and support systems to better meet the needs of those living with SSD. Because of the role of oxytocin in regulating social behaviors and emotions, the investigator hypothesizes that it is beneficial in addressing the social cogn…

The rate of weight gain in the first year of life is risk factor for future obesity. The study will test (1) a model of l mechanisms underlying the development of emotion, attachment, and nutritive intake; and (2) the association with maternal feeding behavior, child eating behavior, dietary intake, and adiposity.

One in five Canadians live with chronic pain, defined as pain that lasts longer than 3-months. Living with chronic pain has a detrimental impact on physical health, emotional health, and quality of life. Current treatments rarely result in pain relief and often do not meaningfully improve physical or emotional function. Further, medication used to treat pain often causes unwanted symptoms. There is a need to develop new treatments to help manage chronic pain. The use of a nasal spray containing manufactured oxytocin may improve pain management. Oxytocin is produced in the human body and has be…

Oxytocin is a medication that is often used to strengthen contractions to overcome delayed labor progress. The primary aim of this study is to determine whether receiving a higher dose of oxytocin lowers the chance of needing a cesarean section when compared to a lower dose of oxytocin. Other aims include examining the relationship between dose of oxytocin regimen and length of labor, postpartum hemorrhage, intrauterine infection, umbilical cord gas, neonatal Apgar score \<5 at 5 minutes, and need for neonatal intensive care.

The project has three overall objectives. The first is to determine whether and how administration of intranasal oxytocin (OT) and intranasal vasopressin (AVP) influence cooperative decision-making and neural responses to cooperative and un-cooperative social interactions. The second is to determine whether and how intranasal vasopressin influences subjective evaluations of and neural responses to same and opposite-sex face stimuli and to determine if any of these effects persist beyond the period of AVP exposure. The third objective is to determine if intranasal OT influences empathy-related …

The percentage of women undergoing an induction of labor (IOL) is estimated to be 20% and continues to rise. Simultaneously, the cesarean delivery (CD) rate has continued to increase (2). Induction is a known risk factor for CD. Despite numerous studies evaluating time periods to define a failed IOL, there are no guidelines or accepted definitions of when to call an IOL failed given the incremental gain in vaginal delivery when IOL is prolonged. While decreasing the CD rate is an important primary focus in obstetrics, attention must also be paid to the overall length of labor given that prolon…

The purpose of this research study is to learn about the effects of supplemental intranasal oxytocin as a treatment for improving social difficulties in children and adolescents with autism. This study will also provide additional information about the safety and tolerability of intranasal oxytocin. Investigators expect oxytocin will increase social motivation, improving daily living skills and quality of life.

Positive social relationships have consistently been associated with better health, although the neurobiological underpinnings of these observed effects remain largely unknown. The overall goal of the proposed work is to explore novel biological pathways that may explain how social relationships influence health. Recent theorizing suggests that the oxytocin system may underlie some of the observed beneficial effects. Four hypotheses will be examined: 1. Oxytocin ameliorates the deleterious neuroendocrine, cardiovascular, and subjective effects of stress. 2. Oxytocin and social support have si…

Alcohol use disorders (AUD) and intimate partner aggression (IPA) frequently co-occur. There are significant health and economic burdens associated with AUD and co-occurring IPA, and little empirical data to guide treatment efforts. The neuropeptide oxytocin may help mitigate both AUD and IPA. However, clinical data examining oxytocin's effects on human aggression is scant. The proposed study is designed to address these gaps in the literature by utilizing a human laboratory paradigm to test the effects of oxytocin on craving and aggression among couples with AUD and co-occurring IPA.

The aim of this project is to create fear conditioning paradigm within which the relative strengths of various novel pharmacological and behavioral interventions can be tested. These interventions are intended to reduce the fearfulness associated with fear conditioning by blocking a memory process known as reconsolidation. In fear conditioning, a "conditioned" stimulus (CS) is paired with an aversive "unconditioned" stimulus (US) such as an electric shock, until presentation of the CS alone comes to elicit a fear conditioned response (CR). The investigators hypothesize that by using a more hig…

Posttraumatic stress disorder (PTSD) is a chronic, debilitating condition that disproportionately affects Veterans. Prolonged Exposure (PE) therapy is a "gold standard" treatment for PTSD. However, approximately one-third of Veterans fail to receive an adequate dose of treatment because they prematurely drop out of PE therapy. There is also room to improve PE treatment outcomes. Consistent with the VA Office of Research and Development initiative to develop effective treatments for PTSD, the proposed randomized clinical trial will examine the ability of oxytocin (as compared with placebo) comb…

Study Purpose: The purpose of this study is to determine the optimal method for induction of labor in multiparous women who present with an unfavorable cervix. Hypothesis: Our hypothesis is that using oxytocin while the cervical ripening balloon is in place will result in more rapid labor courses, without increasing morbidity or increasing the need for operative delivery.

The purpose of the overall parent study is to determine the impact of gender and hormones (estradiol, progesterone, testosterone and cortisol) on responses to stress and smoking cues presented in daily, "real-world" cue presentations compared to a final cue session in a lab. In addition, in the portion of the study that incorporates clinical trials elements and is reported here, the study will examine the impact of a single dose of oxytocin (chemical produced in the body) versus placebo (inactive substance) on reactivity to a stress procedure (Trier Social Stress Task) in smokers. The overall…

The investigators plan to conduct functional MRI scanning with a group of mothers who are blindly and randomly assigned either intranasal oxytocin or a placebo. The purpose of this investigation is to explore how oxytocin may modify early maternal brain and behavioral responses to infant cues. This study will examine, for the first time, a potential pharmacological intervention for maternal neglect which targets core neurobiological deficits. This may eventually be used to supplement and augment other psychosocial and behavioral interventions. In addition, the investigators will examine sex d…

This study will compare the effectiveness of vaginal misoprostol (Cytotec) and intravenous oxytocin (Pitocin) in multiparous women who present at term for labor induction.

The investigators are conducting this research study to examine whether oxytocin enhances social safety learning (learning safety through the experience of another individual) in people with social anxiety disorder (SAD) compared to healthy volunteers. Oxytocin is a hormone that can also act as a chemical messenger in the brain. Oxytocin plays a role in a number of functions, including responding to fear and social interactions. In this study, the investigators would like to compare the effects of oxytocin and placebo nasal sprays in adults with SAD and healthy adults. This research study will…

Stress is likely involved in relapse to cocaine use. This project will investigate the role oxytocin may play in the stress response in cocaine-dependent men and women and examine how oxytocin may impact brain activity in individuals exposed to cocaine-related cues.

Mothers who were enrolled in the Mood, Mother and Infant study will be eligible to participate in the 6-year follow-up maternal visit. At the time of this visit, mothers will be randomized to a single 24 IU dose of nasal oxytocin or placebo. Following administration of the study drug, women will participate in the Trier Social Stress Test (TSST), and blood samples will be collected to quantify HPA axis reactivity.

Premature rupture of membranes (PROM) is a common occurrence of pregnancies at term. A delay from PROM to labor is associated with an increased risk of intrauterine infection and associated maternal and fetal morbidity; therefore, induction of labor (IOL) is recommended. The ideal agent for IOL is not known, particularly among specific subpopulations. The primary aim of this study is to determine if oxytocin (Pitocin) or oral misoprostol results in a shorter interval to delivery after the start of induction among nulliparous women with unfavorable cervical exams with term PROM.

This study will investigate the extent to which intranasal oxytocin affects changes in social decision making and evaluations of others. Oxytocin is a hormone that naturally occurs in the body and the brain and has been shown to be relevant for many behaviors, particularly in social situations. Research on the effects of oxytocin in aging is very scarce; therefore, the purpose of this research project is to determine the effects of oxytocin on socioemotional aging.

Primary: The primary objective of the study is to compare the efficacy of intranasal oxytocin in reducing the weekly percentage of heavy drinking days over the 10 weeks of maintenance treatment among subjects with moderate to severe Alcohol Use Disorder (AUD). A "heavy drinking day" is 4 or more drinks per drinking day for women and 5 or more drinks per drinking day for men. Secondary: Secondary objectives include assessment of other measures of the effects of oxytocin compared with placebo on reduction of alcohol use as well as effects on psychological assessments, alcohol craving, alcohol-r…

The project is designed to address the following two primary aims: 1. To determine whether adjunctive oxytocin is superior to placebo for the treatment of persistent negative symptoms, as measured by the SANS total score, in people with schizophrenia. 2. To determine whether adjunctive Galantamine is superior to placebo for the treatment of cognitive impairments, as measured by improvement on a composite neurocognitive score in people with schizophrenia. The investigators will also address the following secondary aims: 1. To determine whether people with schizophrenia treated with adjunctiv…

Osteoarthritis (OA) represents a significant cause of disability worldwide and the knee is the most commonly affected joint. Oxytocin (OT) is a mediator of endogenous analgesia in animal and human studies. This proposal will test the efficacy and safety of self-administered intranasal OT over 4-weeks in older individuals relative to placebo (P) evaluating its effects on pain and function in aging and testing potential underlying neurobiological mechanisms.

This study is designed to investigate oxytocin's effects on interoception and whether these effects vary as a function of different emotional valence.

Socioemotional processing dysfunctions (i.e., disruptions in affective, cognitive, and neural processes that encode, interpret, and respond to socially and emotionally relevant stimuli) have been implicated in tobacco smoking and relapse, however this potential target for medication development has not been systematically examined. Evidence from animal and human laboratories indicate that administration of intranasal oxytocin enhances socioemotional processing and may be efficacious for the treatment of drug addiction, including nicotine dependence. In order to evaluate the potential efficacy …

In comparison to the general population, military personnel and veterans are at increased risk of developing both substance use disorders (SUDs) and post-traumatic stress disorder (PTSD). Despite promising developments in the past decade, the treatment of patients with SUDs and comorbid PTSD is woefully inadequate (Back, 2010; Back et al., 2014; Brady et al., 2007; McCauley et al., 2012). One of the adverse effects of abused drugs is their long-term negative impact on social behavior that is thought to involve oxytocin (OT) dysregulation (McGregor et al., 2008). In preclinical and clinical exp…

Oxytocin is a promising new medication found to have positive effects on prosocial behavior, reduce negative affect such as fear and anxiety, and reduce stress-induced addictive behaviors. This study aims to investigate the extent to which a 40 IU dose of intranasal oxytocin improves couples' conflict resolution skills and subjective, physiological, and neuroendocrine responses to conflict. Conflict resolution discussions will take place in the laboratory and will be videotaped.

The purpose of this study is to determine whether oxytocin will decrease craving to use drugs/alcohol and stress reactivity following exposure to laboratory-induced stress among Active Duty Service Members with a dual diagnosis of alcohol/substance use disorder (ASUD) and post-traumatic anxiety.

This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin in obese adults, ages 18-45 years old. Subjects will be randomized to receive of intranasal oxytocin or placebo (3 sprays per nostril, 4 times per day) for 8 weeks. Study visits include screening to determine eligibility, a 2-part baseline visit, and visits every 2 weeks thereafter until week 14, with a safety follow-up visit 6 weeks after the last dose of study drug. Study procedures include behavioral, metabolic, neuroimaging, and endocrine assessments.

We are studying an investigational drug called intranasal oxytocin (Syntocinon®). Syntocinon® has been approved by the U.S. Food and Drug Administration for use in helping women breastfeed, but it has not been approved for use in children with ASD. However, there is previous research conducted that has indicated that after administration of oxytocin, adults with ASD demonstrated improvements in social cognition, and reduced repetitive behaviours and anxiety. There is also early research to suggest that children may also benefit in these areas. The purpose of this study is to test if oxytocin w…

The purpose of this study is to learn more about how the hormone, oxytocin, impacts social behavior in terms of cooperation with others, attention processing, and reward processing, among patients with social anxiety disorder. Based on available research, the investigators predict that in patients with social anxiety disorder, oxytocin will improve social cooperation during an online ball-tossing game called Cyberball, reduce attention toward socially threatening cues during a dot-probe task, and lead to greater willingness to work for monetary rewards for others rather than themselves during …

The purpose of the study is to learn how differences in learning under mildly-stressful circumstances may be changed by taking oxytocin. Oxytocin is a hormone made naturally in the body. The investigators will also examine the impact of any anxiety, depression, and stress related symptoms on learning processes.

The purpose of this study is to test a new treatment for preventing childbirth-related mental illness in postpartum mothers. The treatment is aimed at enhancing maternal bonding, reducing postpartum depression (PPD) and anxiety in mothers at risk, and promoting child development. To this end, the investigators will test the clinical utility of intranasal (IN) oxytocin (OXT) administered to mothers during the first postpartum days.

Autism is a pervasive developmental disorder characterized by core deficits in social behavior and communication, and the presence of repetitive or stereotyped behaviors. It is one of three recognized disorders in the autism spectrum which affects an estimated 1 in 88 children in the United States. At present, pharmacotherapies target only associated features of autism, with no effective drug treatments for the social impairments. Several lines of evidence now suggest that the neuropeptide oxytocin (OT) may be an effective treatment for the core social deficits in autism. Here we will test the…

The main goal of the study is to look at the effects of intranasal oxytocin on the brain in Autism Spectrum Disorder (ASD). Oxytocin is a hormone that exists naturally in the body and the brain, affecting a wide range of social behaviors and emotions. The investigators will study the effects of different treatments (3 doses of oxytocin and one dose of placebo) on brain functional connectivity at rest in patients with ASD, using functional magnetic resonance imaging (fMRI). Investigators also seek to study how the effects of oxytocin treatment can be affected by genetic, immune and environmenta…

This study will evaluate the effect of 8 doses of intranasal oxytocin or placebo on two proposed measures of target engagement in brain. The targets are (1) the suppression of a particular wave form (mu) on the electroencephalogram (EEG) while subjects observe a socially relevant form of motion and (2) pupil dilation will subjects identify faces showing different emotions.

Although prior dose-finding studies have investigated the optimal bolus dose of oxytocin to initiate adequate uterine tone, it is unclear what oxytocin infusion regimen is required to maintain adequate uterine tone after delivery. The study investigators aim to compare two different infusion rates of oxytocin to assess the optimal infusion regimen for reducing blood loss in women undergoing elective Cesarean delivery.

The purpose of this study is to specifically investigate the efficacy of an alternative pharmacologic cervical ripening agent, misoprostol, versus the standard oxytocin, as an adjunct to Foley balloon for induction of the unfavorable cervix.

The purpose of this study is to learn more about how emotional processing may be affected by a hormone called oxytocin. Oxytocin is a hormone that occurs naturally in the body, and may play an important role in the way that the brain perceives information.

This proposal describes a combined laboratory and clinical trial preliminary investigation to advance medication development for cocaine dependence. The main objective is to test whether intranasal Oxytocin could reduce relapse risk by reducing stress sensitivity. To measure the stress sensitivity, this study will evaluate a new stress challenge: a) Intranasal desmopressin, a vasopressin analog, will be used an endocrine stressor; its effects will be evaluated by serial measurements of serum Adrenocorticotropin hormone (ACTH), and self reports; b) if pretreatment with intranasal oxytocin dampe…

This study will investigate the effects of intranasal administration of oxytocin, a social neuropeptide, on reducing stimulant use, enhancing therapeutic engagement, and susceptibility to stress-induced relapse in Veterans with stimulant use disorders and enrolled in opioid replacement therapy (ORT) program for co-occurring opioid use disorder (OUD).

The purpose of the current study is to investigate the effect of an acute administration of intranasal oxytocin, relative to placebo, on social cognitive impairments among individuals with body dysmorphic disorder and obsessive-compulsive disorder, compared to healthy controls.

The purpose of this study is to evaluate the feasibility, safety, and preliminary efficacy of integrating targeted dosing of intranasal oxytocin with a social cognitive skills group therapy for school-aged children with autism spectrum disorder (ASD).

The current trial aims to explore the neural and behavioral effects of oxytocin in autism spectrum disorders (ASD). Oxytocin is a nonapeptide produced by the paraventricular and supraoptic nuclei of the hypothalamus and is known to play a pivotal role in a variety of complex social behaviors. Initial studies showed that intranasal administration of oxytocin can have a positive effect on social functioning in ASD. However, future studies are necessary to explore whether and how oxytocin effects neural processes in the brain underlying these behavioral improvements. This trial will not only mea…

The focus of the current project is to advance our understanding of the effects of oxytocin (OT) on components of social cognition in schizophrenia (SCZ). Despite the rapid increase in our understanding of the role of OT in rodent models of social behavior and an explosion of interest in the prosocial effects of OT in healthy controls, little work has been done to dissect the potential effects of OT on SCZ subjects with social deficits. Social deficits are a crucial aspect of the functional impairments that limit the rehabilitation of patients with SCZ. In particular, SCZ patients with endurin…

The purpose of the study is to use fMRI to investigate amygdala response to fearful faces in men and women with and without PTSD who have experienced childhood trauma. The study will also compare the effects of oxytocin and placebo on amygdala response, and explore the interaction of oxytocin plasma levels and amygdala response in men and women with and without PTSD who have experienced childhood trauma. Hypothesis 1: Amygdala responding will be greater in subjects with PTSD as compared to resilient subjects, and no sex differences in the magnitude of the response will be found. Hypothesis 2…

The main objective of this study is to determine the safety and therapeutic potential of intranasal oxytocin in children and adolescents with autism spectrum disorder (ASD) when paired with a computer game intervention that is designed to enhance face perception skills.

Stress is associated with drug craving and relapse in substance-dependent individuals. Hormones released from the brain may mediate the behavioral response to stress. For example, several studies have indicated that oxytocin reduces stress in laboratory stress paradigms. Specifically, it appears that oxytocin promotes trust, social interaction, and calmness; yet, little is known about the potential affects of oxytocin in cocaine-dependent individuals. Given these properties of oxytocin, it may have a therapeutic role in ameliorating the negative affect commonly observed prior to relapse in coc…

This study is a phase 2 randomized double blind 8-week treatment trial of intranasal OXT vs. placebo in 50 subjects aged 5 to 17 years with PWS in order to assess IN-OXT's affect on measurements of (1) eating behaviors (2) repetitive behaviors (3) weight and body composition (4) quality of life (5) salivary OXT and hormone levels (including ghrelin, pancreatic polypeptide, peptide YY, Glucagon-Like Peptide-1 (GLP-1), insulin, glucagon, testosterone, and estrogen). If superior to placebo, this data will add to the current knowledge that OXT is an effective treatment for hyperphagia as well as o…

This is a randomized, placebo controlled, double blind crossover study of the effects of intranasal oxytocin on social cognition, implicit preferences and craving in moderate to heavy social alcohol drinkers.

Objective: Social Cognition and Emotional Intelligence have been shown to be deficient in patients with schizophrenia and these are not remediated by antipsychotic medications or psychosocial interventions. Social cognition is associated with functional outcome, an important step in striving for recovery in this population. The hormone and neurotransmitter, oxytocin, which has been associated with social bonding and trust has been shown to improve measures of some aspects of social cognition in humans. The study will assess the effect of acute administration of intranasal oxytocin on measures …

Autism spectrum disorder (ASD) is a group of severe, life-long developmental disorders. Oxytocin (OT) is a neurohormone involved in both repetitive/rigid and social behaviors. This study is focusing on how a single dose of intranasal OT (IN-OT) affects cognitive rigidity and social perception tasks. Taking OT as a spray through the nose increases social and decreases repetitive behavior in some adults with ASD, and we are exploring if it helps children with ASD similarly. However, it is unclear whether every person with ASD has an abnormal OT level, and if OT affects restrictive or social beha…

Schizophrenia is a complex and heritable disorder that encompasses several clinical symptom domains and functional impairments. Existing treatments of schizophrenia, although effective against positive symptoms, fail to benefit negative symptoms, the focus of the current protocol. One of the strategies of novel drug development depends on identifying heritable physiological deficits that mark the disease liability and are thought to occur along the causal pathway of negative symptoms. These heritable physiological deficits are often found in the biological relatives of schizophrenia proband; p…

The objective of this study is to investigate the effects of oxytocin on social behavior and brain activity using EEG and the event-related potential (ERP) technique. The value of EEG is its high temporal specificity, enabling precision in the timing of social behavior to be addressed. In order to elicit social responses in the human brain, a variety of social and emotional visual stimuli will be presented during EEG recording, namely infant and adult faces and houses. Brain responses after intranasal oxytocin will then be compared with placebo, to examine the effect of intranasal oxytocin on …

The main purpose of this study is to sample blood and model the plasma pharmacokinetics (PK) of a single dose of intravenous (IV) oxytocin and a single dose of intranasal (i.n.) oxytocin. This is an unblinded study of subjects, all of whom will receive an intravenous (IV) infusion and intranasal (i.n.) dose of oxytocin (a naturally occurring hormone that is made in the brain) with blood samples taken thereafter in order to create a formula to describe the concentrations of oxytocin in the blood over time (pharmacokinetics). In this study healthy volunteers and people are recruited for a two …

This is a study of participants that will receive intravenous (IV) infusions of oxytocin (naturally occurring hormone that is made by the brain). In this study healthy participants will be recruited for the study. There will be 3 study related visits: 1) screening and informed consent 2) study medication infusions and thermal heat testing 3) study medication infusions and thermal heat testing. During study visits 2 and 3 an IV catheter will be placed and a dose of oxytocin or placebo (inactive solution) will be given over a 10 minute period; 1 hour after the first infusion, a second 10 minute…

The investigators propose to conduct this pilot study to evaluate oxytocin as a supplemental treatment for improving social difficulties in individuals with autism.

Anecdotal evidence suggests female patients with painful bladder disorder interstitial cystitis (IC) can experience a significant attenuation of their systems while breastfeeding. Since it has been shown that postpartum lactation is a time associated with decreased levels of stress, and stress has been shown to exacerbate IC-related pain, the investigators have developed an interest in the effects of the hormones involved in postpartum lactation on stress and pain. Based on a series of pre-clinical experiments, the investigators believe the hormone oxytoxin has both analgesic and anxiolytic pr…

Oxytocin is normally administered following delivery in pregnant patients to reduce postpartum bleeding by increasing uterine tone. It is unclear whether the use of intravenous oxytocin alters coagulation in pregnant patients. The purpose of the in-vitro study is to assess the coagulation changes of oxytocin in blood samples from pregnant patients using thromboelastrography (TEG). TEG is a point-of-care device which measures the viscoelastic properties of clot formation, and can provide rapid and detailed information about coagulation changes. We aim to collect blood samples from pregnant pati…

The objective of this study is to test a single dose of intranasal oxytocin, compared to placebo, in a within subjects, crossover design, to see if oxytocin will improve satiety signaling (behaviorally and/or by self report) compared to placebo. If this single dose pilot paradigm shows an increase in satiety, it may be tested in follow-up studies as a prevention or treatment for weight gain and overeating in people with schizophrenia.

Individuals with schizophrenia have been found to have deficits in social cognition, which is defined as the functions that are engaged during social interactions. Social cognition has been found to be critical in predicting multiple aspects of community functioning. There are no currently available medications that have been consistently found to improve social cognition in individuals with schizophrenia. Oxytocin functions as a neurotransmitter that is thought to be involved in multiple aspects of social behavior and related emotions. In this study, we test the hypothesis that acute administ…

Obesity is highly prevalent in older adults and is a major cause of sarcopenia and disability in older adults. Although exercise can counteract the effects of obesity and sarcopenia, many have difficulty adhering to an exercise program and the benefits of exercise are variable. Therefore, there is an urgent need to test novel pharmacologic interventions to prevent disability and loss of independence. Oxytocin is a pituitary hormone released during parturition and lactation that is also known to suppress appetite in rodents and humans; and, recent small studies have found that intranasal oxytoc…

The investigators propose a randomized double-blind 8 week treatment trial of intranasal oxytocin (IN-OXT) vs. placebo in 24 subjects aged 5 to 18 years with PWS in order to assess IN-OXT's affect on (1) Eating behaviors (2) Repetitive and disruptive behaviors and (3) Salivary OXT levels.

The goal of this study is to test the effects of oxytocin on heart rate variability and pupil diameter, both of which have subtle effects on the activity rate of the autonomic nervous system.

Purpose: Test whether oxytocin treatment decreases drinking in people who have been consuming alcohol heavily for long periods and are physically and psychologically dependent on alcohol. Participants: 50 adults with alcohol dependence Procedures (methods): Oxytocin or placebo will be administered three times a day for the first 2 days followed by twice daily intranasal doses for the rest of the 12 weeks. Before, during and at the end of the trial, each subject will undergo evaluations including breathalyzer readings, rating withdrawal symptoms, interviews about amount of alcohol consumed si…

Research shows that slow gentle skin stroking can activate special sensory nerves in the skin that elicit relaxing effects on the body and mind, similar to the effects of the hormone oxytocin. Studies also suggest that gentle stroking may even release oxytocin in the skin. However, we do not know what oxytocin does in the skin and how it affects nerves that send pleasant touch or pain signals to the brain. The proposed study will determine how individuals perceive gentle stroking and experimental pain before and after a skin injection of oxytocin compared to a placebo injection.

In 2019 VA mandated that all Veterans seeking mental health care have access to flexible family mental health services in VA (VHA directive 1163.04). This study aims to respond to this mandate by further improving an evidence-based PTSD treatment designed to decrease PTSD symptoms and improve relationship satisfaction for Veterans and their romantic partners. Brief Cognitive-Behavioral Conjoint Therapy (B-CBCT), an 8-session dyadic psychotherapy for PTSD, has been found to significantly reduce PTSD symptoms, but the effects of B-CBCT on relationship satisfaction are less reliable and robust. P…

Although stress has long been linked to substance use, craving and relapse, there are no available medications that target stress-induced substance use disorder (SUD). In particular, with the rise in opioid use, there is still a crucial need for developing effective pharmacological treatments that target and integrate the complexity of this disease. The long term goal of this project is to identify the key neuroendocrine pathways that are responsible for stress-induced craving in individuals with opioid use disorder (OUD) in order to better understand how they can be effectively treated.

Autism Spectrum Disorder (ASD) is a developmental disorder characterized by abnormalities in speech and communication, impaired social functioning and repetitive behaviors and restricted interests. Oxytocin (OT) is peptide that is known for its peripheral effects on facilitating uterine contractions and milk let-down; however, studies, mainly with rodents and non-human primates, has found that OT is involved in affiliative behaviors, including sexual behavior, mother-infant and adult-adult pair-bond formation, separation distress, and other aspects of social attachment. Moreover, OT is known t…

The purpose of this study is to learn whether or not the drug called oxytocin is helpful in improving mood and social functioning in adults with autism.

This is a pilot study examining the efficacy, safety and tolerability of intranasal oxytocin as a novel treatment in Phelan-McDermid syndrome (PMS). This study will utilize a randomized, placebo-controlled design for 12 weeks (phase 1), followed by an open-label extension for 12 weeks (phase 2). The purpose is to evaluate the effect of intranasal oxytocin on impairments in attention, social memory, socialization, language, and repetitive behaviors.

Subjects-currently in outpatient mental health care--will participate in 2 psychotherapy sessions, one with oxytocin spray and one with placebo spray. Sessions will be videotaped, and cortisol and heart rate will be measured. We hypothesize that oxytocin will have positive benefits on nonverbal behavior in the therapy session, as well as have positive effects on subjective anxiety, cortisol and heart rate.

Posttraumatic stress disorder (PTSD) is a chronic, debilitating anxiety disorder that may develop after direct or indirect exposure to traumatic events. Prolonged Exposure (PE) is a cognitive-behavioral psychotherapy modality with a wealth of empirical support demonstrating its efficacy to treat PTSD in a variety of populations. The neuropeptide oxytocin is a promising new pharmacotherapeutic agent with prominent anxiolytic effects . Despite a strong biological and theoretical rationale for investigating the potential effectiveness of augmenting PE with intranasal oxytocin, no studies to date …

Also, determine rates of subject recruitment and retention in the inpatient setting. Participants: 80 alcohol dependent patients, 18-65 years of age, admitted for medical detoxification. Procedures (methods): Subjects will be inpatients undergoing medical detoxi…

This study will test in individuals who have alcohol dependence (alcohol addiction) the hypotheses 1) that intranasal oxytocin treatment will decrease withdrawal symptoms during medical detoxification and 2) that intranasal oxytocin treatment for 12 weeks in the outpatient setting will decrease drinking.

Purpose: The purpose of this research study is to learn whether oxytocin treatment decreases use of and cravings for opioids (narcotics) in people who have been using opioids heavily for long periods of time and are unable to stop on their own. Participants: Patients meeting DSM-IV-TR criteria for opioid dependence. Procedures (methods): Subjects will have standard medications available for withdrawal symptoms from opioids and standard psychosocial interventions available in the inpatient setting. In addition, subjects will self-administer intranasal test treatments 3 times daily.

In this pilot study the investigators will perform a double-blind randomized trial of intranasal oxytocin on measures of cardiac refractoriness, among individuals who are undergoing clinically indicated catheter ablation procedures for paroxysmal atrial fibrillation. The investigators seek to enroll 20 patients for this study, for the purpose of estimating effect sizes for a larger future study.

Individuals with alcohol use disorder (AUD) will complete one functional Magnetic Resonance Imaging (fMRI) scanning visit. Prior to the scan, individuals will receive a nasal spray of either 24 international units (IU) of oxytocin (OT), or placebo (PBO). During the scan, they will perform the Montreal Imaging Stress Task (MIST), a social stress task. Subjective craving and anxiety data will be collected.

The investigators will use multiple methods (including Oxytocin intranasal inhalation, neuroimaging, behavioral measures, peripheral hormone measurements) to examine how individuals' behavior, cognition, and brain function is impacted by the neuro-hormone Oxytocin. Specifically, the investigators plan to evaluate the influence of Oxytocin administration on affective processing in non-trauma exposed and trauma-exposed adults (both with and without posttraumatic stress disorder, PTSD).

This study proposes to evaluate the effects that a dose of oxytocin given by intramuscular (IM) injection (into the muscle) will have on an area of skin that has been exposed to ultraviolet (UV) light. The area of skin exposed to UV light will have a mild sun burn feeling. Sensory testing will be performed on the area of UV burn. The area will be evaluated for sensitivity in 3 methods: touch, vibratory

OSA is a very prevalent disease with high cardiovascular risk factors, yet this disease remains very poorly treated. This proposal, based on the current literature and new basic science results detailed above on the role of oxytocin in cardiovascular control, will test if oxytocin administration improves adverse cardiovascular events during the recurrent nocturnal apneas in patients with OSA. This project will lay the groundwork and provide preliminary da…

This study is an 8-week open-label trial testing oxytocin nasal spray (Syntocinon) as a treatment for social impairment in adolescents with autism spectrum disorders (ASD). We hypothesize that oxytocin nasal spray will be safe, tolerable, and effective in improving the core symptoms of autism spectrum disorders in adolescents ages 11-17.

This study is an 8-week pilot trial with oxytocin nasal spray (Syntocinon) as a treatment for social impairment in children and adults with high functioning autism spectrum disorders (ASD). The investigators hypothesize that oxytocin will be safe, tolerable, and effective in improving social deficits in individuals with ASD.

The purpose of this study is to measure the impact of a discontinuous administration of oxytocin during the active phase of the 1st stage of labor on the neonatal morbidity rate. The investigators hypothesize that discontinuation of oxytocin in the active phase of labor (from 6 cm) in women who received oxytocin in the latent phase or for an induction (before 4 cm of dilation) could reduce neonatal morbidity.

In a randomized control trial conducted in six study centers/labour wards in Sweden, consenting nulliparous women in active phase of labour and with a defined delayed labour progress will be randomized to receive a regimen of either high or low dose of oxytocin. Primary outcome is caesarean delivery rate. Secondary outcomes are: Apgar score, need of neonatal intensive care, hyper-stimulation of contractions, spontaneous vaginal birth rate, length of labour, postpartum haemorrhage, sphincter lacerations, experienced labour pain, epidural analgesia and the women´s childbirth experience one month…

The patients were recruited from women attending labor ward to undergo cesarean section.

Objective: To compare active labour outcomes in nulliparous women at term supervised with a partograph with the action line placed at either 2 hours or 4 hours and to determine whether the 2-hour action line placement is better for the prevention of prolonged labour. Design: Randomised controlled trial. Setting: A university teaching hospital in Nigeria. Population: Nulliparous women in labour at term. Method: Nulliparous women in labour were randomly supervised with a partograph with the action line placed at 2 hours (n=320) or 4 hours (n=320). Oxytocin augmentation, when required, was us…

Secondary goals are to measure and compare the time intervals to delivery between the two methods.

This study attempts to identify the psychological, behavioral, physiological, and hormonal predictors and mechanisms of an individual's ability to develop cohesion in a group working together as a team; and examine if administration of the prosocial neuropeptide oxytocin enhances the development of team cohesion. Through a deeper understanding of the underlying psychobiological predictors and mechanisms of team cohesion, the prospective identification of individuals whose unique characteristics promote or inhibit the development of group cohesion will become possible.

During the first hours that follow the birth of the baby (third and fourth stages of labor), complications are common and can threaten the mother's life. The most common complication is postpartum hemorrhage (PPH), which remains a leading cause of maternal mortality (25.0%) especially in developing countries .Three to five percent of deliveries are complicated by PPH and is 50 times more common in developing countries. Retained placenta is an another complication of third stage of labor. It complicates 0.1-2 % of deliveries . Without prompt treatment, women are at high risk of hemorrhage. At p…

Postpartum hemorrhage (PPH) is potentially life-threatening and is a significant contributor to maternal mortality and morbidity especially in developing countries. The risk of PPH is much higher for women undergoing cesarean delivery (CD). In the majority of cases, uterine atony is responsible for the occurrence of excessive bleeding during or following childbirth. The Millennium Development Goal of reducing the maternal mortality ratio by 75 % by 2015 will remain beyond our reach unless we prioritize the prevention and treatment of PPH in low-resource countries. Consequently, the administ…

Postpartum haemorrhage keeps to be the leading cause of maternal mortality in middle and low-income countries, including Iraq. Much advancement had been made in the field of treatment for postpartum haemorrhage but no much progress had been made in the field of prevention, where one of its main component is the administration of uterotonic, preferably oxytocin, immediately after birth of the baby. In many low- and middle income countries, the efficacy of oxytocin cannot be assured since access to sustained cold-chain is unavailable. Regarding the other uterotonics; ergometrine degrades when e…

The use of Oxytocin for labor induction may cause receptor exhaustion and thus making its use in the third stage of labor ineffective in reducing post partum blood loss as compared to other uterotonics.So, we studied the effect of other uterotonic which is misoprostol in reducing post partum hemorrhage.

Mothers are given the medication oxytocin after birth to help the uterus (womb) contract and therefore reduce blood loss. In Canada, oxytocin is given either into the muscle of the thigh or into a vein. However, it is not known which route is better.This study will test which dose and route of oxytocin is best in reducing blood loss following vaginal delivery.

Double blinded randomized controlled study

The cesarean section is a bloody operation, about 750 to 1000 ml are lost at most operations and over 1000 ml of blood have lost to bring them into the definition of a postpartum hemorrhage (PPH). In developing countries, PPH is the main cause of maternal deaths. Uterine atony is the most common cause of immediate heavy PPH.Multiple pregnancy ones of a common factor for uterine atony. The administration of oxytocic's after the delivery of the neonate reduces the likelihood of PPH and 5 IU oxytocin by slow intravenous injection is currently recommended for all cesarean sections. However, the us…

Postpartum hemorrhage (PPH) is a common complication of childbirth and a leading cause of maternal morbidity and mortality. The prompt and effective treatment of subjects with PPH would reduce operation risks. Hence in this study, the efficacy of Oxytocin and Carbetocin was compared in prevention of postpartum hemorrhage after cesarean sections.

The purpose of this study is to determine if giving oxytocin immediately after delivery causes less bleeding, transfusion needs and hastens delivery of placenta.

The purpose of the study is to examine whether oxytocin and certain polygenic risk scores affect the development of intrusive memories, a cardinal symptom of PTSD.

Increasing cesarean rate in France is worrying. Different methods are described for ripening labor : the use of prostaglandins is described but maybe dangerous for patients with scarred uterus and is not recommended. Intracervical balloon is an efficient alternative methods which as already been tested for unfavorable cervix ripening on nulliparous women. But it was rarely tested on women with scared uterus and unfavorable cervix (bishop score \<4). The investigators propose a prospective randomised trial comparing cervix ripening with intracervical balloon inflated by 50 ml sterile water d…

Cesarean delivery is defined as fetal birth through incisions in the abdominal wall and the uterine wall. This definition does not include removal of the fetus from the abdominal cavity in the case of uterine rupture or in the case of an abdominal pregnancy The guidelines of the Royal College of Obstetricians and Gynaecologists on caesarean section recommend a slow intravenous bolus dose of 5 IU of oxytocin after delivery of the infant. Intravenous oxytocin has a short half life (4-10 minutes); therefore the potential advantage of an oxytocin infusion at caesarean section is in maintaining ute…

The goal of this study is to determine the best dose of a drug called oxytocin, that is usually used to stop bleeding during a delivery, when used during a cesarean delivery. It will be administered during cesarean section in order to decrease the amount blood loss. The investigators are proposing to have 3 groups of subjects each given a different safe dose of oxytocin and then to assess the effectiveness of each regimens on the amount blood lost during cesarean sections.This will let use know which is the best lowest dose needed.

The main aim of the study is to investigate the modulatory effects of oxytocin (24IU) administration on the affective processing of touch manipulated differently in gentle caress-like stroke vs. social massage with a moderate pressure.

The primary objective of the proposed Stage II study is to examine the efficacy of oxytocin (OT) as compared to placebo in reducing (1) alcohol use disorder (AUD) symptoms, and (2) post-traumatic stress disorder (PTSD) symptoms among Veterans receiving COPE therapy (Concurrent Treatment of PTSD and Substance Use Disorders using Prolonged Exposure). To evaluate purported neurobiological mechanisms of change, we will employ functional magnetic resonance imaging (fMRI) at pre- and post-treatment.

It has long been established that interpersonal relationships can have a profound impact on health and well-being. Yet, the investigators are still learning about the complex biological processes that contribute to positive social interactions and the ability to develop and maintain social relationships. Recent research has begun to focus on oxytocin, a neuropeptide that is naturally produced in the hypothalamus, because administration of this neuropeptide has been associated with increased trust, generosity, empathy, cooperation, memory of social stimuli (e.g., faces), and brain activity in n…

One well-established cognitive theory propose a divide between social and non-social (i.e., cognitive) systems. However, recent work suggests that traditionally social systems can be utilized to enhance cognitive performance. In this study the investigators aim to explore this cooperation between oft-competing systems by instructing participants to learn information because they will be subsequently tested (the nonsocial learning-for-testing condition), or because they will be teaching the information to someone else (the prosocial learning-for-teaching condition). This latter condition relies…

High-potency benzodiazepines have strong anxiolytic effects accompanied by significant adverse effects including impaired cognitive function, drowsiness, dizziness and impaired motoric abilities. Importantly, the long-term use of benzodiazepines may produce dependence and withdrawal. Therefore, there is considerable scientific and public interest in identifying new anxiolytic agents. The hypothalamic peptide oxytocin (OXT) has anxiolytic effects both in healthy participants and patients with anxiety disorders by decreasing fear-associated amygdala activity. However, so far no human study has …

Labour is usually physiologic, spontaneous and progressive, but occasionally, there may be the need for induction or augmentation of labour especially in nulliparous women, who are at increased risk of dysfunctional labour. Oxytocin traditionally has been used for induction and augmentation of labour however prolonged labour continued to occur with attendant sequelae. Newer agents like propranolol, with minimal to no maternal and fetal adverse effects in labour have been shown to decreases the duration of labour when used in synergy with oxytocin. However, the paucity of information on the use…

Patients having Cesarean section after they have been in labor for many hours bleed much more, in average twice as much, as compared with patients having an elective Cesarean section. The investigators believe a simple change in practice might contribute to reduce this bleeding. This study will involve the use of oxytocin (also known as syntocinon), ergonovine (also known as ergot) and carboprost (also known as hemabate). Oxytocin is routinely used to help contract the uterus and keep it contracted after the delivery of the baby and placenta, so as to reduce the amount of blood loss. Ergonovin…

Observe effects of oxytocin on individuals with autism spectrum disorder

Placebo responses contribute to medical treatment outcome. The purpose of this study is to determine whether a single intranasal application of oxytocin can increase the placebo response in an experimental model of placebo analgesia in healthy volunteers.

This study evaluates whether intranasal administration of a single dose of oxytocin improves the ability to recognize emotional states. In a cross-over design, half of the participants first received oxytocin, the other half first received placebo.

Up to 50% of all postmenopausal women, experience vaginal dryness, irritation, burning, itching or discomfort, which often make sex to become difficult or painful. These symptoms combined are known as vaginal atrophy. Vaginal atrophy is a consequence of the lining tissue of the vagina becoming thinner, drier, and less elastic due to the lack of estrogen. In addition, vaginal atrophy is associated with an increased pH, which creates an environment more susceptible to infections. The mucosal epithelium shows signs of severe atrophy and cytological examination demonstrate increased number of the …

A pharmacoimaging study of oxytcoin in antisocial personality disorder and psychopathy

The main focus of this study is to examine oxytocin effects on behavioral and neural indices of empathy processing.

The main objective of this project is to study whether intranasal oxytocin (OT) affects how young adults perceive and attend to infant and adult faces. Based on existing research the investigators predict that oxytocin will facilitate the allocation of attentional resources on infant faces (compared to adult faces). The investigators also predict that oxytocin will enhance the activity of reward neural-networks associated with the perception of infant faces. The behavioral effects of OT (visual attention and face recognition) will be measured with eye-tracking while participants look at photog…

Severe traumatic experiences such as falling victim to assault, torture, or rape have deleterious effects. Clinical manifestations include intrusions, avoidance behavior, and hyperarousal, which are associated, at a circuit level, with hyperfunction of the amygdala and hypofunction of prefrontal cortex (PFC) subregions. In up to 50 % of the cases, resilience is not sufficient and trauma-exposed individuals develop posttraumatic stress disorder (PTSD). Oxytocin (OXT) is a hypothalamic peptide hormone that exerts anxiolytic effects. Recent clinical trials provide preliminary evidence that post-t…

There is substantial evidence from animal model and healthy control data, that oxytocin is involved in the modulation of social cognition. In addition, recent genetics and plasma level studies suggest a possible role for oxytocin in the pathophysiology of Autism Spectrum Disorders (ASD). As a large number of children with ASD are transitioning into adulthood and will likely require treatment, the lack of data to make meaningful treatment recommendations to facilitate adult living is an urgent issue. This study will examine the effect of intranasal oxytocin (IN-OXT) on social function in adults…

The goal of this clinical trial is to learn if oxytocin administered as a nasal spray will reduce withdrawal symptoms in adults during benzodiazepine tapering for 21 days. It will also learn about the safety of oxytocin. The main questions it aims to answer are: Does oxytocin reduce benzodiazepine withdrawal symptoms and make it easier to succeed tapering? Does oxytocin help reduce sleep difficulties and anxiety or restlessness during benzodiazepine tapering? Does oxytocin help reduce benzodiazepine craving? We will compare oxytocin nasal spray to a placebo nasal spray containing regular sal…

Participants were randomized using computer-generated random numbers into 2 groups. Group I included 32 women who received oxytocin infusion before placental delivery just after cord clamping and group II included 32 women who received oxytocin infusion after placental delivery. In both groups 10 IU of oxytocin (Syntocinon, Novartis, Basel, Switzerland) were diluted in 500 mL of normal saline and administered through intravenous infusion over 30 minutes.

The purpose of the study is to examine the effects of intranasal oxytocin administration on social cognition in patients receiving methadone maintenance treatment (MMT), examine the effects of intranasal oxytocin administration on opioid craving and on the subjective effects of methadone, and examine the effects of intranasal oxytocin administration on implicit preferences for drug-related and social stimuli in patients receiving MMT. Hypothesis 1: Patients will perform better on measures of social cognition (including affect recognition and recognition of sarcasm) after administration of oxy…

Alcohol use disorder (AUD) is a chronic relapsing disorder. Alcohol craving, a hallmark symptom of AUD that drives relapse in patients, is only insufficiently treated by existing medication. One promising new compound is Oxytocin (OXY), which showed beneficial effects on alcohol craving in preliminary clinical studies. Additionally, OXY seems to enhance effects of established medication, specifically Naltrexone (NTX), an opioid-antagonist which is approved for AUD treatment via positive synergism on neurotransmitter levels. The proposed two-armed, 1:1 randomized, double-blind, parallel group t…

There is no previous study on the hemostatic effect of intrauterine instillation of oxytocin in hysteroscopic myomectomy. All previous studies focused on intravenous administration of oxytocin. This trial may modify the surgical environment in hysteroscopic myomectomy by decreasing intraoperative bleeding to a degree that the amount of distention medium required for uterine distention will be reduced with a better visibility and shorter operation time. The standard treatment of symptomatic myomas is hysterectomy for women who have completed childbearing period, and myomectomy for women who w…

Studies found conflicting results on efficacy of uterotonic agents used to prevent and treat uterine atony, the most common cause of postpartum hemorrhage. Uterine EMG can be used to objectively assess myometrial contractility and, consequently, efficacy of different uterotonics. The investigators are planning a single-center, randomized, open-label trial to compare uterine EMG parameters in women receiving oxytocin vs. those receiving carbetocin after cesarean delivery.

Hypot…

The investigators explored the neural and behavioral effect of oxytocin on youth with Autism spectrum disorder using magnetoencephalography (MEG). The investigators hypothesize that oxytocin will modulate neural activity to resemble patterns observed in the age-matched control group. Thirty-two adolescents with autism and 26 typically developing adolescents participated in this randomized, double-blind MEG study. Individuals with autism arrived at the lab twice and received an acute dose of intranasal oxytocin or placebo in each session. During the scans, participants were asked to complete s…

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). …

The purpose of this study is to compare the ability of a sample of uterine muscle tissue to contract in the presence of various drugs. The drugs studied are typically used to contract the uterus when a pregnant patient continues to bleed after delivery. Amongst the uterotonic drugs (used to contract the uterus), namely oxytocin, ergonovine and carboprost, the most effective one to use is not known. The investigators will be testing uterine muscle samples in the presence of these drugs at various concentrations, to see what their contractility measures over time, as compared with a control sam…

schizophrenia patients and healthy volunteers will be included. Subjects who meet the inclusion and exclusion criteria for the study will be recruited. After completion of clinical assessments and neuropsychological assessments, all subjects will undergo two fMRI scans. In one scan subjects will receive a single dose of intranasal oxytocin and in another scan, they will receive intranasal saline. The order of administration of oxytocin or saline will be counterbalanced so that they are not administered in the same order to all subjects. Subjects will be blind to the drug administered.

This study will evaluate the effects on emotions and neural activity of a one time dose of intranasal oxytocin vs. placebo in patients with FTD and healthy controls.

This experiment will explore the joint effects of social information, social support, associative learning, and oxytocin on the development of placebo analgesia. The investigators predict that socially transmitted placebo effects will be enhanced by nasal administration of oxytocin, whereas associative learning effects on pain will not be altered by this pharmacological manipulation

Aim of the current study: To evaluate the effect of a14 day treatment period with local intravaginal application of an oxytocin-containing gel on vaginal atrophy, psychosexual and psychological/cognitive function, and metabolic, stress, and inflammatory parameters in Egyptian post-menopausal women

This study investigates whether oxytocin, a neuropeptide known for its role in social bonding, influences the outcomes of persuasive communications and several primary evolutionary goals. Participants will be given either oxytocin or placebo on their first visit and then they will receive the other spray during their second visit. At each visit, participants will engage in several psychosocial tasks to assess the role of oxytocin on receptiveness to opposing opinions, navigating the spatial environment, mating and parenting goals. Participants' attitudes and behaviours will be compared across …

The main aim of the study is to investigate whether intranasal oxytocin (24IU) increases the affective processing of touch in general or whether it's effect vary according to the affective valence of the touch (positive, neutral, negative). Moreover, associations with trait autism will be explored.

The investigator thinks that the oxytocin (OT) can improve durably and significantly the behavior disorders and thus the socialization but also the satisfaction and could thus be an interesting therapeutic alternative for the patients presenting a Prader-Willi Syndrome (SPW). Although today several studies demonstrated the effects of the OT in various domains of the behavior, the investigator do not know either its specificity of action about the cerebral level, or its duration of action, or the optimal modalities of administration and in particular at patients SPW.

Fifty pregnant patients with acquired and congenital heart disease between 38-41 weeks were randomised into elective induction and spontaneous labour groups only after bishop score was equal to or more than 6.It was concluded that induction of labour with oxytocin is a relatively safe procedure in women with low risk heart disease with NYHA class I and II. It resulted in a similar caesarean delivery rate and was not associated with more maternal and neonatal complications.

Postpartum hemorrhage (PPH) is a major cause of maternal death worldwide. Oxytocin is the most commonly used uterotonic drug for the active management of third stage labor, to reduce the risk of PPH and help deliver the placenta. Carbetocin is currently recommended by the SOGC (Society of Obstetricans \& Gynecologists of Canada), and is a relatively newer drug with a longer duration of action. It has been previously demonstrated that women with elevated BMI require higher doses of these drugs to induce adequate uterine contraction and dose finding studies undertaken at Mount Sinai Hospital hav…

The purpose of this pilot study is to determine the tolerability, feasibility, and preliminary effectiveness of intranasal oxytocin administration prior to motivational enhancement group therapy sessions on laboratory-based measures of addiction, social connectedness, and stress responsivity in methamphetamine(meth)-using men who have sex with men (MSM). The investigators propose a randomized, double-blind, study of intranasal oxytocin versus placebo 40 IU prior to each of six Motivational Interviewing Group Therapy (MIGT) sessions in 28 mixed HIV sero-status MSM initiating treatment for amphe…

The purpose of this project is to investigate the possible effect of intranasally administered Oxytocin (OT) on specific mirror neuron areas in human brain. The mirror neuron system (MNS) is thought to be involved in action perception and understanding, and may also underlie more complex cognitive processes such as imitation. We will use electroencephalographic (EEG) investigations to examine brain activity while participants complete two different tasks, consisting of the observation and imitation of emotional facial expressions (video presented) and the observation and execution of simple gr…

In previous studies the neuropeptide oxytocin has been in particular associated with social enhancing and anxiety relieving effects. The purpose of this study is to investigate the effect of oxytocin on empathy in patients with schizophrenia. On a neurobiological level, social effects mediated by oxytocin are based on oxytocin's influence on the complexly regulated mesocorticolimbic dopamine system. Preliminary studies have already shown that oxytocin increases neuronal connections between social reward expectancy networks and networks for socioemotional processes in the brain, which on a beh…

Naval Special Warfare (NSW) operators are exposed to a variety of extreme environmental conditions and intense physical demands. In addition to breathing high pressure gases at depth, prolonged cold water immersion and inadequate recovery from sustained physical exertion negatively impact individual and team performance. Biotechnologies that could mitigate the effects of cold as well as support physical recovery represent a significant unmet need for the NSW operational community. Oxytocin (OT) has a wide range of actions both locally in the brain and peripherally in the body including skelet…

This study is designed to determine the minimal effective oxytocin maintenance dose required during cesarean delivery to achieve the best effect. Oxytocin is a drug which is routinely used to help contract the uterus and keep it contracted after the delivery of the baby and placenta. The aim of oxytocin is to reduce the amount of blood that might be lost. In order to determine the minimal effective dose, the investigators will conduct a dose-finding study. The first patient will receive a set oxytocin infusion. If the uterus contracts well, this is considered satisfactory and the next patient …

This study evaluates the effect of oxytocin nasal spray on alcohol withdrawal and dependence in adults admitted for detoxification of alcohol, and during the following 4 weeks in an outpatient setting. Half of the participants will receive oxytocin nasal spray, the other half placebo nasal spray.

Social touch can convey the most potent and salient of socio-emotional signals. While the hypothalamic peptide oxytocin (OXT) has been identified as a key neurochemical mediator of grooming in some other social species, its modulatory influence on human interpersonal touch is unknown. The investigators expect that OXT augments the hedonic value of touch and that this behavioral effect is paralleled at the neural level by an increased response in brain areas mediating rewarding aspects of social touch.

This study aims to answer the question: Does oxytocin increase the pain threshold on thermal heat pain in the presence of vibration on an area of skin exposed to a mild sunburn?

This study is an assessment of the long-term effect of oxytocin nasal spray on alcohol withdrawal and dependence in adults admitted for detoxification of alcohol after 60 days and 1 year.

Half of the participants have received oxytocin nasal spray, the other half placebo nasal spray (NCT02903251). (added March 2019: 24 patients were available for 1-year follow-up)

The clinical study evaluates in an open-label, crossover design the comparative efficacy and safety of intranasal oxytocin and autologous umbilical cord blood for improving the functioning of children with autistic spectrum disorder

Because oral probiotics reported to potentially induce endogenous Oxytocin, and Oxytocin has been reported to improve social behaviors, the investigators will conduct a pilot trial to compare the effects of probiotics and Oxytocin on social behavioral changes in ASD children. Additionally, the investigators will check oxytocin levels, and perform brain fMRI in some subjects, in order to determine which treatment is more efficient, sustainable, and practical, and whether both treatments in combination are better than either treatment alone. If the trial is conclusive, the investigators will con…

To investigate whether and how intranasal oxytocin of 8IU treatment will alter the topology of functional brain network in resting-state and multiple tasks in healthy males.

This is a 4 part study: Phase 1a. -functional magnetic resonance imaging (fMRI) ( with oxytocin 24 IU vs. placebo = oxytocin 0 IU) - funded by grant #U54 HD079124-01, Phase 1b-eye-tracking(oxytocin 24 IU vs. placebo = oxytocin 0 IU), Phase 2a. fMRI (oxytocin 8 IU vs. oxytocin 40IU), Phase 2b. -eye-tracking (oxytocin 8IU vs. oxytocin 40IU). Time course of effect will also be assessed within session.

Background: A large body of research has shown that Oxytocin (OXT) is an important prosocial peptide and there is also initial evidence that the central OXT system is altered in several mental disorders that are characterized by severe social disturbances and deficits, such as anxiety disorders with prominent social dysfunction (e.g., schizophrenia), mood disorders and borderline personality disorder. OXT may reduce psychotic symptoms and may diminish certain social cognition deficits that are not improved by current antipsychotic medications. Aims: The project has two main aims, listed below…

Oxytocin (OT) is a neuropeptide that acts as a neurotransmitter and neuromodulator in the brain. Previous studies have shown that intranasal administration of OT improves social cognition and behavior (e.g. emotion recognition). In the current study, we want to gain more insight into the underlying mechanisms by which OT influences emotion recognition. More specifically, we will investigate whether intranasal administration of OT enhances the salience of social (compared to non-social) information and whether it increases the neural sensitivity for subtle socio-emotional cues, by recording sca…

Postpartum hemorrhage (PPH) due to uterine atony is a major cause of maternal morbidity and mortality. Uterotonic drugs are used to improve the muscle tone of the uterus after birth and these are effective at reducing the incidence of PPH. Large doses of this drug are associated with adverse effects like lower blood pressure, nausea, vomiting, abnormal heart rhythms and changes on ECG. Various international bodies recommend varying and high doses of oxytocin in elective cesarean sections. A study performed at Mount Sinai Hospital showed that a much smaller doses of oxytocin is required (ED95 b…

Exciting advances have led to the concept that hormones can modulate appetite and food intake. Oxytocin is a peptide hormone that is released in regions throughout the brain, including areas involved in food motivation. Animal studies suggest that oxytocin may reduce food intake. The effects of oxytocin administration on eating behavior in humans, which could have important implications in eating-related disorders ranging from obesity to anorexia nervosa, have not been investigated. This double-blind placebo-controlled cross-over study of single-dose oxytocin administration investigates whethe…

The goal of this research study is to find out how well oxytocin works to reduce pain. Oxytocin will be given intravenously (IV) and as a nasal spray. The study team also hopes to find out if the participants age, weight, or sex effects how well the study drug works. Participants will be exposed to a heater on the skin at a training visit and rate how much pain different temperatures cause. On two separate visits, participants will use a nasal spray and get an IV infusion. After the IV and nasal spray, participants will rate the pain of the same skin heating temperature at various time points…

This is a randomized, double-blind, placebo-controlled crossover study of single-dose intranasal oxytocin (24 IU) in 18-55 year-old men with attention deficit/hyperactivity disorder (ADHD). Following a screening visit to determine eligibility, participants will return for two main study visits.
