Oxytocin at Elective Cesarean Deliveries: A Dose-finding Study in Women With BMI ≥ 40kg/m2

Start date: May 2019
Phase: N/A
Study type: Interventional

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. Oxytocin is the most commonly used uterotonic drug to prevent and treat PPH. Large doses of this drug are asociated with adverse effects like low 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 dose of oxytocin is required (ED95 being 0.35IU). However, most of the women included in this study were below a body mass index (BMI) of 40kg/m2. The investigators seek to find the best dose for patients with a BMI>40kg/m2, as a higher dose may be needed in this population to contract the uterus adequately.

NCT ID: NCT03956849 Recruiting - Clinical trials for Overweight and Obesity

Talking With Children About Weight and Lifestyle

Start date: February 13, 2019
Study type: Observational

Obesity among children is a major problem. Therefore, it is important to start promoting a healthy lifestyle in an early stage. However, professionals find it difficult to start a conversation about overweight and lifestyle. Within Centre for Overweight Adolescent and Children's Healthcare (COACH) at the Maastricht University Medical Centre (MUMC+) a tool was developed, based on motivational interviewing, to help professionals engage in conversation with the children about weight and lifestyle. The aim of this study is to identify barriers and facilitators perceived by professionals, working with children, to start a conversation with a child with overweight or obesity about weight and lifestyle. In addition, this study researches the effects of the developed COACH Conversationstarter, a tool that can help healthcare professionals to start a conversation with children about overweight and lifestyle and to gain more insight in the views, thoughts and beliefs of the child and its family.

NCT ID: NCT03955952 Enrolling by invitation - Obesity Clinical Trials

Cardiovascular Outcomes in Bariatric Surgery Patients With Type 2 Diabetes

Start date: January 5, 2019
Study type: Observational

The objective of the analysis was to evaluate the relationship between bariatric surgery and cardiovascular outcomes in obese patients with type 2 diabetes. This is a retrospective matched cohort study of patients with diabetes that underwent bariatric surgery at the Cleveland Clinic between 2004-2017. Each bariatric patient was matched to a non-surgical control with obesity and type 2 diabetes in a 1:5 ratio using data from the Electronic Medical Record (EMR). The maximum observation time was 10 years. Cumulative incidence rates for all-cause mortality and cardiovascular events were calculated at years 1, 3, 5, 7 and 10. Kaplan-Meier curves were created for all the outcomes with all-cause mortality considered as a completing risk.

NCT ID: NCT03951857 Recruiting - Obesity Clinical Trials

Effect of Aging & Obesity With Exercise Intervention

Start date: November 18, 2016
Phase: N/A
Study type: Interventional

Obesity leads to a vicious circle that increases intramuscular fat, insulin resistance, promotes muscular dysfunction resulting in increased muscle fat accumulation. The study of muscle function and intramyocellular lipids is insufficient for obesity. Particularly, the study of mechanisms in muscle function and intramyocellular lipids is few nationally and internationally.

NCT ID: NCT03951285 Active, not recruiting - Obesity Clinical Trials

Nicotinamide Riboside and Mitochondrial Metabolism

Start date: May 25, 2016
Phase: N/A
Study type: Interventional

Vitamin B3 has recently been found to be a potent modifier of energy metabolism, especially the function of mitochondria. Mitochondria power up all cells in our bodies, by generating fuel, ATP, for cellular functions. In previous studies, it has been discovered that mitochondrial biogenesis and oxidative metabolism in adipose tissue is severely impaired in obesity, already at a young adult age. Here the investigators describe a proposal where they use nicotinamide riboside (NR), a form of vitamin B3 naturally found in milk, to activate dysfunctional mitochondria, in particular the SIRT/NAD+ pathway, and to rescue signs of obesity-related diseases. The investigators use a unique human study design: monozygotic twins either discordant or concordant for obesity, to examine the effects of NR on mitochondrial function in muscle, adipose tissue and the metabolism of the whole body. The upcoming upcoming results are important for understanding the links between mitochondrial dysfunction and chronic metabolic diseases in humans, as well as for clarifying mechanisms of the novel nutritional therapeutic approaches.

NCT ID: NCT03950661 Completed - Obesity Clinical Trials

Walking Green: The Effects of Walking in Forested and Urban Areas

Start date: June 1, 2016
Phase: N/A
Study type: Interventional

This research hypothesizes that moderate physical activity in a "green environment" (e.g. a forest preserve path) has increased benefits on psychological measures (stress, anxiety, mood, depression, attention) and on physiological measures (Heart Rate Variability, Blood Glucose, Salivary Cortisol) when directly compared to activity in a "gray environment" (urban or suburban sidewalks). The study design is a randomized crossover design in which each subject is assigned randomly to a group which determines the order in which participants will walk in each location. Subjects will take three 50-minute walks per location in one week, with half of the subjects taking the urban walks first as per group assignment. Control data are collected on days when participants do not walk. Physiological data are taken during walks and control periods (heart rate, heart rate variation). Biomarker samples (saliva, dried blood spots) are taken on selected days. Psychological data are take before and after walks and control periods.

NCT ID: NCT03950453 Recruiting - Child Obesity Clinical Trials

Preventing Childhood Obesity Through a Mindfulness-Based Parent Stress Intervention

Start date: November 11, 2018
Phase: N/A
Study type: Interventional

This study will examine the mediator/moderator variables of family composition, food insecurity, adversity and emotion regulation for effects on parent stress, parenting, health behaviors and child obesity risk.

NCT ID: NCT03949595 Completed - Obesity Clinical Trials

Rapid Eating Is Linked to Emotional Eating in Obese Women Relieving From Bariatric Surgery

Start date: November 1, 2011
Study type: Observational

The aim of the study was to analyse eating rate in comparison to other aspects of eating habits in women suffering from severe/massive obesity.

NCT ID: NCT03948061 Not yet recruiting - Obesity Clinical Trials

Cardiometabolic Effects of Sweet Cherry Juice

Start date: June 1, 2019
Phase: N/A
Study type: Interventional

This study aims to determine the effects of consuming sweet cherry juice on cardiovascular function, glucose regulation, and lipid status in overweight human subjects. The investigators hypothesize that sweet cherry juice consumption will improve metabolic and physiological status in overweight persons compared to a placebo.

NCT ID: NCT03947697 Recruiting - Obesity Clinical Trials

A Novel Treatment Intervention for Improving Metabolism

Start date: October 12, 2018
Phase: N/A
Study type: Interventional

Once written consent is obtained, the participant will be provided with an accelerometer to be worn for 7 days to assess current physical activity levels. Subjects will be provided with a standardized diet (55/15/30% CHO/PRO/FAT) prior to collection of pre-intervention data of insulin sensitivity. Individuals will then participate in an 8-week electrical stimulation intervention (30min/day, 3x/week) and randomized into placebo/control, NMES, resistance training combined with NMES (RT +NMES), or resistance training (RT) group (n=15 per group), followed by collection of post-intervention data. The control group will receive electrical stimulation up to sensory level, the NMES group will receive stimulation up to tolerable intensity to induce visible muscle contraction, the RT+ NMES will receive stimulation up to tolerable intensity during resistance training, and the RT group will only receive exercise training. Pre-and post-intervention data includes measurements for body composition, resting metabolic rate, VO2max, insulin sensitivity, and comprehensive blood work.
