The Boston Cognitive Assessment (BoCA) is a self-administered online test intended for longitudinal cognitive monitoring. BoCA uses random not-repeating tasks to minimize learning effects. BoCA was developed to evaluate the effects of treatment in longitudinal clinical trials and available gratis to individuals and professionals. Read Less

Depression is a leading cause of morbidity and mortality, conferring substantial healthcare and societal costs. By studying methods to non-invasively target neural circuitry involved in reward responsivity, information generated by this project will improve understanding of the circuit alterations that underlie motivation and pleasure deficits in depression, and could also lead to the development of biologically-based markers of neurostimulation-based treatment response.

This is a Phase 1b, open-label study evaluating Venetoclax in combination with intensive induction and consolidation chemotherapy in previously untreated, adult patients with acute myeloid leukemia. In Part 1, the dose escalation phase, the safety and tolerability of the combination with Venetoclax at different doses and duration will inform the appropriate dose(s) and regimen(s) for Part 2. In Part 2, the dose expansion phase, a maximum of 28 additional patients will be randomized 1:1 to the MTD determined in Part 1 and the starting dose (assuming the MTD is not the starting dose), to further evaluate the safety and efficacy of the study drug combination.

Physical activity is the most beneficial and cost-effective treatment for Veterans with PAD, however, issues with oxygen delivery and utilization dramatically impair exercise compliance. The cause of these oxygen delivery and utilization impairments is likely increased oxidative stress and inflammation. The proposed project will comprehensively examine the novel strategy of Nuclear Factor Erythroid-2-like 2 (Nrf2) activation using PB125, aimed at diminishing oxidative stress and inflammation, and thereby lessening the negative impacts of the disease. This therapeutic will be evaluated in isolation and in combination with exercise rehabilitation to determine if there is a complimentary benefit. The ultimate goal is to provide insight into a potential novel therapeutic treatment for this disease, therefore, improving exercise tolerance and quality of life in this growing population.

Deficits in motivation and pleasure are common in depression, and thought to be caused by alterations in the ways in which the brain anticipates, evaluates, and adaptively uses reward-related information. However, reward processing is a complex, multi-circuit phenomenon, and the precise neural mechanisms that contribute to the absence or reduction of pleasure and motivation are not well understood. Variation in the clinical presentation of depression has long been a rule rather than an exception, including individual variation in symptoms, severity, and treatment response. This heterogeneity complicates understanding of depression and thwarts progress toward disease classification and treatment planning. Discovery of depression-specific biomarkers that account for neurobiological variation that presumably underlies distinct clinical manifestations is critical to this larger effort. Read Less

The purpose of this study is to assess the effect of Tranexamic Acid Oral Solution 5% in patients treated with direct oral anticoagulants or vitamin K antagonists and undergoing a single or multiple tooth extraction. Read Less

Using a randomized controlled trial design, the investigators will examine the effects of music engagement through choir training on the hearing, communication, and psychosocial well-being of older adults, particularly those at heightened risk of developing dementia. Read Less

The purpose of this study is to determine the effects of suvorexant (SUVO), on sleep, stress, and drug craving during early abstinence from stimulants and to determine the effects of treatment (SUVO vs. treatment as usual (TAU)) on post-treatment (Days 13-30) residential program length of stay (LOS) and completion rate.

Despite medical advancements, PTSD remains a major issue in Veterans1. Current treatment strategies have relatively poor adherence. In patients with PTSD and cirrhosis, there is greater cognitive impairment as well as changes in gut microbiome structure and function2,3. In addition, when there is concomitant cirrhosis, medication-related treatment options become even narrower from a safety and tolerability perspective and cognitive issues pertaining to cirrhosis could impact participation3. Changes in gut microbiome in Veterans with cirrhosis and PTSD compared to those with cirrhosis without PTSD is characterized by a greater relative expression of pathobionts and reduction in stool microbiome diversity with reduction in bacteria that produce beneficial short chain fatty acids (SCFA)2. Modulation of the gut microbiome in patients with cirrhosis and PTSD may be an important therapeutic target. In prior studies with cirrhosis alone, microbial modulation using diet, antibiotics such as rifaximin, probiotics, and fecal microbiota transplant have improved gut microbial diversity and clinical outcomes in some cases4,5. In patients with cirrhosis without PTSD and in patients with PTSD without cirrhosis there is emerging evidence regarding prebiotics and other forms of gut microbial modulation. Prebiotics are such an example6. Prebiotics are natural fibers derived from carbohydrates and can be beneficial to gut microbiota (good bacteria in the gut)6. Resistant starches (RS) are dietary fiber prebiotics found naturally in many foods including potatoes, plantains, and legumes6,7. In addition to being highly accessible, RS have been shown to be well tolerated with few adverse reactions. While no studies of RS exist in PTSD + cirrhosis patients, a meta-analysis of RS in IBD has shown RS to be an effective treatment in both animal and clinical studies where improvements in clinical remission and reduced mucosal damage were found7. However, there is insufficient data regarding patients with PTSD and cirrhosis regarding gut microbial structure and function modulation with dietary supplements such as resistant starches. These starches can improve SCFA production in elderly subjects, which could in turn affect the gut-brain axis favorably8. Read Less

The purpose of this study is to compare opioid prescribing practices by either routine provider prescribing practices, or with the use of a calculator, i.e., the Opioid Calculator, published by the University of Michigan (www.opioidcalculator.org), with the intent of decreasing the number of pills.

The goal of this study is to identify the effects of sleep regularity on cardiovascular regulatory mechanisms. The investigators are hoping to discover if improving the regularity of sleep timing will improve metabolic and vascular health markers. The protocol is a 12-week prospective cohort study that includes both field and in-laboratory data collection in ostensibly healthy male and female adults, aged 18-40years. Read Less
