NAUTICAL: Effect of Natriuretic Peptide Augmentation on Cardiometabolic Health in Black Individuals...
Diabetes MellitusCardiovascular Diseases5 moreBlack individuals are more likely to have decreased insulin sensitivity which results in a high risk for the development of cardiometabolic disease. The reasons for this are incompletely understood. Natriuretic peptides (NPs) are hormones produced by the heart that play a role in regulating the metabolic health of an individual. Low circulating level of NPs is an important contributor to increased risk for diabetes. The NP levels are relatively lower among Black individuals thus affecting their metabolic health and putting them at a higher risk for diabetes. This study aims to test the hypothesis that by augmenting NP levels using sacubitril/valsartan, among Black Individuals one can improve their metabolic health (as measured by insulin sensitivity & energy expenditure) and help establish the role of NPs in the underlying mechanism behind increased risk for cardiometabolic disease in these population.
Effect of Tirzepatide Plus Intensive Lifestyle Therapy on Body Weight and Metabolic Health in Latinos...
ObesityMetabolic DiseaseThe purpose of this study is to conduct a three-arm 52-week, randomized controlled trial with double blind treatment to evaluate the effects of a drug called tirzepatide in combination with an innovative, culturally-appropriate, intensive lifestyle intervention (ILI) delivered by community health workers (CHWs) in Latino adults with obesity. Participants will be randomized to 1) standard care (SC, n=25); 2) culturally-tailored dietary and behavioral intensive lifestyle intervention (ILI, n=25) provided by CHWs plus placebo; or 3) ILI plus tirzepatide (ILI-TRZ) for 52 weeks to evaluate the intervention's effect on: i) weight loss; ii) clinical efficacy (change in body fat mass, liver fat, intra-abdominal fat mass and intrahepatic triglyceride content, oral glucose tolerance, glycemic control, insulin sensitivity and b-cell function, plasma lipids, blood pressure, sleep duration, quality and behaviors, physical performance scores); iii) adherence and fidelity to the intervention (adherence to the intervention and barriers to long term adherence, quality-of-life, fidelity of the implementation by CHWs, CHW's and study participants' acceptability and satisfaction with the intervention and eating behaviors. Placebo or tirzepatide will be injected subcutaneously in the abdomen or thigh once a week for 12 months.
Metabolic Effects of Bariatric Arterial Embolization vs Bariatric Surgery
ObesityType2diabetes2 moreObesity and Type 2 diabetes mellitus (DMT2) are two of the most common chronic diseases of the Western society. Obesity is one critical factor in DMT2 development, with weight loss having profound beneficial effects on DMT2 and improving the metabolic pathophysiology leading to hyperglycemia. Observational studies reported that surgical intervention of morbid obesity achieved significant improvement of resolution of DMT2, both in short and long-term. Bariatric surgery has been considered the best option for treatment of diabetic obese patients, with the laparoscopic Roux-en-Y Gastric Bypass being the gold standard of the surgical treatment. Bariatric arterial embolization (BAE) technique has proved to be safe effective for weight loss in obese patients, but its metabolic effects have not been studied yet. The hypothesis of the study is that BAE is effective for the resolution of DMT2 inpatients with BMI between 30-43 Kg/m2. The aim is to assess DMT2 remission after BAE and bariatric surgery, to analyze potential conditioning factors, and to compare remission criteria between bariatric surgery and BAE.

Insomnia Treatment and Cardiometabolic Health in Older Adults With Posttraumatic Stress Disorder...
Posttraumatic Stress DisorderInsomnia2 moreThis pilot randomized controlled trial will address a gap in knowledge related to addressing modifiable risk factors for cardiometabolic disease through treating residual insomnia, sleep difficulties that remain after successful treatment of another condition, in the context of PTSD in understudied older adults. This study provides a non-medication treatment for PTSD called Cognitive Processing Therapy (CPT) followed by one of two non-medication sleep education and treatment programs for sleep problems that remain after completing PTSD treatment in older adults with PTSD. The aims of this project are to evaluate 1) the added benefits of treating residual insomnia on sleep and PTSD symptoms; 2) the added benefits of treating residual insomnia following CPT on cardiometabolic risk biomarkers and quality of life; and 3) the durability of the sleep, PTSD, cardiometabolic and quality of life benefits of treating residual insomnia following CPT at 6-month follow-up in older adults with PTSD.
Saskatoon Berry on Metabolism and Gut Microbiota in Healthy Subjects
Nutritional and Metabolic DiseasesDiabetes becomes epidemic in worldwide countries. Nine out of ten diabetic patients are type 2 diabetes (T2D). T2D is characterized by insulin resistance and obesity. Uncontrolled diabetes leads to serious consequences including heart attack, stroke, chronic renal failure, liver failure, blindness and low limb amputation. Most of hypoglycemic medications have side effects. Natural foods or nutraceuticals with hypoglycemic potential are expected to provide a safer management for diabetic patients. Saskatoon berry is a popular fruit in Canadian Prairie and Northern states in USA. Our recent studies demonstrated Saskatoon berry powder (SBp) attenuated hyperglycemia, hyperlipidemia, insulin resistance, inflammation, liver steatosis and gut dysbiosis in diet-induced insulin resistant mice, a model for T2D. The results in antidiabetic activities of SBp have been supported by other groups in high fat fed rats. The combination of findings suggest that Saskatoon berry is good candidate of prebiotic functional food as a supplemental remedy for reducing insulin resistance, metabolic syndrome and preventing or managing T2D. The effect of Saskatoon berry and its products on metabolic disorders have not been studied in human subjects. We propose to examine the effect of oral administration of freeze-dried Saskatoon berry on glucose metabolism, insulin resistance and gut microbiota in healthy adults in a pilot trial.

Non-invasive Brain Stimulation Normalizes Dopaminergic Transmission in the Frontostriatal Circuit...
DepressionDepression and metabolic disorder (MetD) are two of the most common and debilitating disorders worldwide, occurring with significant rates of comorbidity. This is a major clinical challenge as the outcomes of both conditions are worsened. Studies have uncovered that depression and metabolic disorder are associated with chronic, low-grade inflammation. In brain circuit level, patients with depression are characterized with aberrant frontostriatal (FS) circuit connectivity and reduced activity level that also associated with metabolic comorbidity. In neurotransmitter level, the dopaminergic pathway, that could be feedback regulated by immune and metabolic factors, has long been known to involve in emotional and metabolic homeostasis. More importantly, this dopamine (DA) input is critical to shaping the FS circuit-level dynamic connectivity and plasticity. Therefore, this study hypothesizes that inflammatory and metabolic dysregulations on DA transmission link to the aberrant FS function that cause mood and metabolic syndromes. To clarify the underlying mechanisms, 90 patients who meet the DSM-5 diagnostic criteria of major depressive episode in either major depressive disorder or bipolar disorder are planned to be recruit. FS functional connectivity and activation, before and after receiving 10 Hz repetitive transcranial magnetic stimulation (rTMS) to left dorsolateral prefrontal cortex will be measured. Then systemically analyze participants' clinical symptomology, neurocognitive function, inflammation and metabolic status. Possible correlations between indices, the effects of rTMS and differences between groups will be tested. Results could provide a chance for further understanding the pathophysiology of depression with MetD and comparing between unipolar and bipolar depression, and developing brain circuit based non-invasive brain stimulation personalized treatment for depression with MetD to achieve a better outcome.
Countermeasures to Circadian Misalignment
Circadian Rhythm Sleep Disorder of Shift Work TypeMetabolic Disease1 moreInsufficient sleep and circadian misalignment are independent risk factors for the development of obesity and diabetes, yet few strategies exist to counter metabolic impairments when these behaviors are unavoidable. This project will examine whether avoiding food intake during the biological night can mitigate the impact of circadian misalignment on metabolic homeostasis in adults during simulated night shift work. Findings from this study could identify a translatable strategy to minimize metabolic diseases in populations that include anyone working nonstandard hours such as police, paramedics, firefighters, military personnel, pilots, doctors and nurses, truck drivers, and individuals with sleep disorders.
Healthcare Intervention Program on Treatment Adherence in People With Newly Diagnosed Type 2 Diabetes...
Treatment AdherenceQuality of Life1 moreType 2 Diabetes Mellitus (T2DM) is a group of metabolic disorders characterized by hyperglycemia in the absence of treatment, positioned in the first places of prevalence and mortality in the Mexican population. Adherence to treatment is a central element to prevent complications of the disease, where the active participation of the patient in his or her treatment is fundamental. Despite institutional healthcare efforts to promote this element, there is no clarity in the Clinical Practice Guidelines aimed at the attention of people with T2DM on how to achieve it. The aim of this project will be to evaluate the effect of an intervention based on Contingency Behavior Analysis on treatment adherence, quality of life and glycemic level in people with newly diagnosed T2DM. Pre-experimental design with pretest and posttest measurements. The Dependent Variable will be an intervention based on Contingency Behavior Analysis. The Independent Variables will be adherence to treatment, quality of life and glycemic level. The power calculation suggests an n = 38, using sequential non-probability sampling. People older than 18 years with less than 5 years of T2DM diagnosis will be included. Pretest and posttest differences, effect size and correlations between measurement variables will be analyzed. It is expected that the intervention based on Contingency Behavior Analysis will encourage the active participation of people with T2DM, improving their adherence to treatment, glycemic level and quality of life. Considering that the Clinical Practice Guidelines emphasize the importance of therapeutic adherence through the active participation of the patient and his/her environment, it is expected that this project will provide the tools for behavioral change that so far are not included in public health in Mexico.
