NCT ID: NCT03693859 Not yet recruiting - Obesity Clinical Trials

Smart Gaming in Obesity

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

Obesity (Body Mass Index ≥ 30 kg/m2) is associated with diminished executive functioning. The primary objective of this randomized, controlled trial is to evaluate the efficacy of a behavioral weight loss program coupled with enhanced executive functioning training via serious gaming on weight loss and weight loss maintenance in adults with obesity and executive functioning deficits compared to adults undergoing standard behavioral treatment alone (N = 200). Serious gaming interventions that target the specific cognitive functions needed for weight-loss maintenance may improve long-term weight-loss success.

Examining Reach and Implementation of an Evidence-based Weight Loss Program in Rural Primary Care

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

The majority of American adults do not meet recommended guidelines for healthy eating or physical activity and are overweight or obese, which puts them at risk for chronic disease, poor quality of life, and increased personal and public health care costs. Despite the development and success of a number of evidence-based weight management interventions, these programs have lacked systematic and consistent translation in clinical practice or community services. Further, few of these interventions have been tested in rural populations, where there is a disproportionally high number of obese individuals, and resources to support such programs are lacking. Primary care clinics have the necessary resources to support such programs, and might be the ideal setting to intervene and address concerns of weight loss and management in rural areas. The intent of the proposed project is to increase the capacity of primary care in rural Nebraska to translate evidence-based weight management approaches into practice, improve the speed of uptake and the likelihood of sustainability, and reach a large and representative group of individuals. To achieve this, the investigators will 1) conduct a limited effectiveness and feasibility study to determine impact on weight loss of 100 overweight and obese adult patients in a rural Nebraska primary care clinic, and 2) test multiple strategies for recruitment to determine best practices for program reach. The primary outcome for program effectiveness is percent body weight loss, and the primary outcome for program feasibility is reach, defined as the proportion of individuals who enroll in the program per each recruitment strategy. The proposed project provides a means of implementing an evidence-based weight loss program in rural Nebraska, has the capacity to create meaningful change in patient weight status, and has the potential to influence future efforts to translate evidence-based weight management programs into rural primary care practice.

NCT ID: NCT03690076 Not yet recruiting - Obesity Clinical Trials

Human Cardiac Mitochondria in Acute Endocarditis and Obesity

Start date: October 2, 2018
Study type: Observational

Data about human cardiac mitochondria are cruelly lacking in the literature. However, damages of the activity of these organelles are often the source of abnormal cardiac function in several pathologies. The purpose of this study is to develop a model of purified human cardiac mitochondria, to verify the purity of these organelles and to validate the authenticity of their function in acute endocarditis and obesity, two situations known to alter their activity. Animal studies have shown that microbial infection reduced mitochondrial metabolism whereas obesity increases it. The investigator's hypotheses are the following: 1) acute endocarditis, a form of cardiac microbial infection, reduces the function of human cardiac mitochondria; 2) obesity (body mass index > 30) activates the metabolism of human cardiac mitochondria.

NCT ID: NCT03688438 Not yet recruiting - Obesity Clinical Trials

WoundVac in Obese Patients Undergoing Lumbar Surgery

Start date: October 15, 2018
Phase: N/A
Study type: Interventional

This is an open label, randomized clinical trial of Closed-Incision Negative-Pressure Therapy to decrease post-operative wound complications in patients with BMI ≥35kg/m2 after posterior lumbar spine surgery.

NCT ID: NCT03687424 Not yet recruiting - Obesity Clinical Trials

Can High-flow Nasal Oxygenation Improve Oxygen Saturation During Analgo-sedation in Obese Adults?

Start date: October 30, 2018
Phase: N/A
Study type: Interventional

Obesity is omnipresent problem in everyday anesthesiology practice associated with low level of blood oxygen (hypoxemia) during analgo-sedation. Overweight outpatients are often scheduled for colonoscopy usually undergo analgo-sedation. In obese patients, intravenous analgo-sedation often diminish respiratory drive causing hypoxemia. To avoid hypoxemia, low-flow nasal oxygenation (LFNO) of 2-6 L/min is applied via standard nasal catheter to provide maximum 40 % of inspired fraction of oxygen (FiO2). LFNO comprises applying cold and dry oxygen which causes discomfort to nasal mucosa of patient. LFNO is often insufficient to provide satisfying oxygenation. Insufficient oxygenation adds to circulatory instability - heart rate (HR) and blood pressure (BP) disorder. On the other side, high-flow nasal oxygenation (HFNO) brings 20 to 70 L/min of heated and humidified of O2/air mixture up to 100% FiO2 via specially designed nasal cannula. Heated and humidified O2/air mixture is much more agreeable to patient. HFNO brings noninvasive support to patients' spontaneous breathing by producing continuous positive pressure of 3-7 cmH2O in upper airways consequently enhancing oxygenation. Investigators intend to analyze effect of HFNO vs. LFNO on oxygen saturation during procedural analgo-sedation for colonoscopy in obese adult patients. Investigators expect that obese patients with preserved spontaneous breathing, oxygenized by HFNO vs. LFNO, will be less prone to hypoxemia thus more respiratory and circulatory stable during procedural analgo-sedation for colonoscopy. Obese patients with applied HFNO should longer preserve: normal oxygen saturation, normal level of CO2 and O2, reflecting better respiratory stability. Investigators expect obese participnts to have more stable HR and BP, reflecting improved circulatory stability. There will be less interruption of breathing pattern of obese patients and less necessity for attending anesthesiologist to intervene.

NCT ID: NCT03686657 Not yet recruiting - Obesity Clinical Trials

Evaluation of Superiority of Valsartan+Celecoxib+Metformin Over Metformin Alone in Type 2 Diabetes Patients

Start date: August 5, 2019
Phase: Phase 1/Phase 2
Study type: Interventional

Evaluation of safety, tolerability and superiority of RK-01, a valsartan plus celecoxib dual add-on to metformin-HCL XR over metformin in newly diagnosed and obese adult type 2 diabetes patients with high blood pressure, arthritis and inadequate glycemic control with metformin monotherapy, diet and exercise over 26 weeks of treatment. Objective: To assess effect of RK-01 on HbA1c levels, beta cell function and insulin resistance with co-administration of valsartan, celecoxib and metformin-HCl XR relative to metformin monotherapy. Hypothesis: After 26 weeks of treatment with valsartan, celecoxib and metformin-HCl XR provides greater improvements in glycemic, inflammatory and atherogenic parameters compared to metformin monotherapy.

Exercise After Clinically Significant Weight Loss

Start date: September 15, 2018

NCT ID: NCT03678974 Not yet recruiting - Obesity Clinical Trials

Bridging Resources Improve the Development of Guideline-based Exercise

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

The purpose of this pilot study is to more effectively deliver the current standard of care for obesity and physical activity based on current guidelines. The investigators plan to gather preliminary data on physician-directed Intensive Behavioral Therapy for Obesity (IBT-O) utilizing CardioCoachCO2 by KORR technology to measure oxygen consumption both at rest and during exercise to assess resting metabolic rate (RMR) and cardiorespiratory fitness (CRF) respectively. RMR and CRF will be incorporated into an exercise prescription through implementation of the CardioCoach VO2 Max App as part of a multi-level physical activity intervention to improve CRF and decrease obesity by acting on multiple levels of the socio-ecological model in a primary care setting.
