Filter by:There are currently no treatments to specifically target asthma in obese adults. This pilot study is being conducted to investigate how effective roflumilast is in treating asthma in participants that have a higher BMI. Roflumilast can induce weight loss, which may lead to improved asthma control. The primary objective of TRIM is to perform a pilot placebo-controlled trial of roflumilast for the treatment of poorly controlled obese asthmatics.
Lifestyle behaviors such as sleep, diet, and physical activity, are implicated in a number of chronic conditions including hypertension, obesity, diabetes, heart failure, and obstructive sleep apnea. Research shows that despite awareness of this fact, patients at risk for lifestyle-related chronic diseases have difficulty adhering to lifestyle change recommendations made by their physicians, and face challenges when attempting to modify unhealthy behaviors. New technologies, such as wearable activity trackers and automated text messaging, are promising tools for monitoring and promoting healthy lifestyle behaviors among patients. This randomized controlled trial will evaluate the effect of a digital health program, which uses pre-medical post-baccalaureate or undergraduate health coaches, wearable activity trackers (Fitbit Charge 2), and mobile messaging, compared to wearable activity trackers (Fitbit Charge 2) alone in promoting lifestyle change among overweight and sedentary 18-64 year old patients recruited from UCLA Health primary care clinics.
Existing obesity prevention efforts have had limited success among underserved, low-income children. This study capitalizes on the strengths of a nationwide ongoing Home Visitation Program (HVP), which serves at-risk, low-income, ethnically/racially diverse mothers and their infants, to test the effectiveness of delivering obesity prevention as part of their weekly, in-home services. The study will evaluate whether the integration of an obesity prevention enhancement module into existing HVP services, reduces the risk and incidence of obesity and associated risk factors in mothers and infants, compared to the provision of standard home visitation services. The study also focuses on the role of maternal factors (maternal diet, physical activity, food insecurity and feeding practices) and social factors (social network support) as mechanisms operating on infant outcomes.
The study evaluated the effect of non-invasive positive pressure ventilation (NIPPV) to decrease the incidence of desaturation events in patients with severe obesity undergoing upper endoscopy.
The aims of this study are as follows: AIM 1: To examine the weight loss and weight maintenance efficacy of an alternate day fasting-high protein (ADF-HP) diet; AIM 2: To examine the effects of an ADF-HP diet on metabolic disease risk factors (plasma lipids, fasting glucose, fasting insulin, insulin resistance).
Obesity and its related conditions account for up to 5%of all health care spending in the UK and this is expected to double by 2030. Following weight loss, significant improvement in these obesity-related illnesses has been reported. However, there is limited understanding of how these improvements happen and in particular, little dedicated work has been done using imaging in the obese population to look at the effects of treatment. Magnetic resonance imaging (MRI) is an imaging technique that allows assessment of fat concentration and volume without the use of ionising radiation. It is safe, non-invasive and well-tolerated by most patients. There are several MRI imaging techniques that be can used for fat quantification. These include MR spectroscopy and Dixon methods with measurement of fat fraction. These techniques measure the fat in the body organs and also the fat in the abdomen and skin. Recent technical developments mean that the whole body can be scanned relatively quickly (typically 30-40 minutes).
This research investigates obesity and associated psychiatric symptoms and disorders in a wide range of perspectives, to demonstrate the effects of obesity on the brain. The 1st aim is to assess the psychiatric symptom profiles in the group of obese patients applying for bariatric surgery and to determine the associated environmental stress factors. While, it is known that eating disorders, mood disorders and psychiatric drugs can cause obesity, obesity can also cause many psychiatric complications such as depression and cognitive disorders. There are no multi-centered studies that are conducted in this respect, and the guidelines on pre-evaluation and follow-up of patients are also lacking. The 2nd aim is to evaluate and monitor cognitive characteristics before and after bariatric surgery in obese patients. Obese people are at increased risk of dementia and are more likely to have cognitive deficits, especially executive function problems, that can affect everyday life. For this reason, obese individuals should be examined and monitored in more detail in terms of their cognitive characteristics and the change of cognitive functions during the weight loss process. The 3rd aim is to examine the relationship between obesity, bariatric surgery and reward processing system. Studies have been limited in determining whether addiction in these people is due to a search of a continuous substance as a cognitive feature or whether it is difficult to terminate it as an impulsive behavior when encountered with a pleasurable substance, even though there is no reward seeking or reward dependence. The 4th aim is the determination of the neuroanatomical and molecular components of cognitive changes observed after bariatric surgery. During the dynamic process following bariatric surgery, a variety of metabolites, chemokines, and microbiota changes may also affect the brain health and cognition. The 5th aim is to determine factors of eating, emotional regulation, reward system, addiction and impulsivity, and other psychopathologies that cause suboptimal weight loss or weight gain after bariatric surgery. Understanding the psychological and neurobiological factors involved in these processes can improve surgical interventions and significantly increase the quality of life for patients.
Regular exercise is a cornerstone in the prevention and the management of cardio-metabolic risk factors. Some of the beneficial effect of exercise training occurs through metabolic flexibility' enhancement. Metabolic flexibility is the ability to respond or adapt to conditional changes in metabolic demand, and previous literature has shown that individuals living with obesity have an impaired metabolic flexibility compared to lean individuals. However, there is a lack of empirical evidence on the impact of sprint interval training on metabolic flexibility and whether this translates into clinically meaningful outcomes. This study will evaluate the impact of 4-week sprint interval training in normal weight individuals as well as individuals living with obesity on acute and chronic metabolic flexibility, irisin secretion and insulin sensitivity.
Approximately one-third of Canadian children have excess weight, putting them at increased risk of type 2 diabetes, cardiovascular disease, bone and joint problems, and some forms of cancer. Because current therapies for managing obesity have modest success, there is a need to develop and test innovative strategies to enhance pediatric weight management. Using a novel interview designed to measure motivation to change lifestyle habits, interviewers will conduct separate and structured 1-on-1 interviews with youth with obesity and parents. By applying principles of motivational interviewing, trained interviewers will ask youth and their parents about their motivation to change lifestyle habits related to diet and physical activity. Subsequently, interview data will be used to examine predictors of clinically-meaningful outcomes over time, including changes in weight status, lifestyle habits, health care utilization, and attrition. The investigators will also measure a number of variables related to weight management, including dietary intake, physical activity, anthropometry, and psychosocial health.
TRIM is a randomized, controlled feeding study to evaluate if eating earlier in the day vs. later in the day impacts weight and glucose homeostasis.
