The goal of this study is to determine how a drug class called glucagon-like peptide-1 receptor agonists (GLP-1Ra) affects people during an early stage of Type 1 Diabetes undergoing clinical teplizumab treatment. This study involves giving participants a liquid meal under different conditions and observing how their bodies respond, focusing on blood sugar levels, insulin effectiveness, and blood vessel function. The meal tests are followed by two post-treatment tests, one with the GLP-1Ra drug and the other with a placebo. Each test involves blood draws before and during the meal test, GLP-1Ra or placebo administration, and an ultrasound to measure blood vessel function. The goal is to see if GLP-1Ra can help manage blood sugar levels and improve cardiovascular health in this population.

The 5-year K01 Mentored Research Scientist proposal will employ brain, neurocognitive, and computational tools (e.g., machine learning) to understand the impact of opioid-use disorder (OUD) and common co-occurring issues on executive function and clinical outcomes. There have been record numbers of fatal and non-fatal overdoses (ODs) associated with opioids (and other drugs) in the past 12-months. Improving classification and predictive capabilities to enhance treatment and prevent relapse is of the upmost importance. Deficits in neurocognition often are associated with poor treatment outcomes (e.g., more drug use, medication non-adherence), yet co-occurring issues associated with OUD (e.g., depression, anxiety, physical/sexual abuse, neglect) make it difficult to parse which contributing factors lead to worse executive function (EF) and poorer treatment outcomes. Novel brain, neurocognitive, and computational tools are needed to help determine these differences, in order to lay the foundation for better treatments. This need has shaped both the training plan and the associated research project in a 5-year K01 Mentored Research Scientist proposal, building on Dr. Regier's prior preclinical and clinical addiction neuroscience experience (focused mostly on cocaine-use disorders, cue-reactivity, subcortical networks, prior adversity, and univariate imaging techniques).

The Duke ApoL1 Nephropathy Biorepository aims to address needs within non-diabetic kidney failure research by utilizing existing and, when necessary, developing new infrastructure to support the consent of patients and the collection of dedicated samples for ApoL1 Nephropathy biorepository. The mutations in ApoL1 gene that are strongly associated with kidney disease are only present in individuals of recent African ancestry (i.e., black people). Caucasians do not have these ApoL1 mutations nor the associated kidney disease. Therefore, majority of subjects recruited for this study will be self-identified African Americans, Afro-Caribbean and other black individual. Study subjects will include individuals with end stage kidney disease and those without any clinical evidence of kidney disease. Additionally, healthy black adults with no known history of kidney disease will be recruited as controls in this study because they are the only group that can fill this role.

The LIFT will be conducted at Brigham and Women's Hospital (BWH) of Harvard Medical School, focusing on the effect of Pyridostigmine (Mestinon) and Low-Dose Naltrexone (LDN) in subjects aged 18-70 meeting the Canadian consensus criteria (CCC) for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) as well as having specifically Orthostatic Intolerance (OI). Long COVID (LC) subjects will also be included if they meet CCC and have OI. This double-blind, placebo-controlled study will involve 160 participants randomized into one of four possible groups: Pyridostigmine/LDN (40), Pyridostigmine/Placebo (40), LDN/Placebo (40), Placebo/Placebo (40). The dose of Pyridostigmine will be carefully titrated from 30mg to 60mg three times a day, and the dose of LDN will be titrated from 1.5 mg to 4.5 mg once daily. The trial includes a scale-back plan, allowing participants to reduce their dosage if they experience intolerance symptoms, with adjustments made during weekly visits. This plan provides a personalized approach to medication tolerance, ensuring participant's safety and comfort throughout the trial. The time commitment for the participant is approximately three (3) months, and during this time, there will be three (3) in-person visits to BWH and four (4) virtual visits. Study procedures will include two (2) submaximum cardiopulmonary exercise tests, questionnaires (virtually completed), and blood and urine collection. We will be recruiting from the BWH Dyspnea Clinic as well as the Open Medicine Foundation (OMF) StudyME Registry and anticipate the entire trial will take two (2) years to complete. The LIFT represents a significant endeavor to improve treatment options for ME/CFS patients and contribute to the broader understanding of this debilitating condition.

In this study the investigators are proposing to evaluate the efficacy, sustainability, and mechanisms of 3 months of individualized counseling of the FRD delivered by registered dietitians, over 8 sessions by phone/video conferencing on fatigue, quality of life, and associated symptoms in persistently fatigued lymphoma cancer survivors compared to 3 months of individualized counseling of the attention control (matched for time and frequency of interactions with the FRD) the General Health Curriculum (GHC). The investigators will randomize and follow 68 lymphoma cancer survivors; accounting for a ~10% drop out rate to achieve a target of 60 patients that will complete the study. The investigators hypothesize that persistently fatigued lymphoma cancer survivors will experience improvements in fatigue, quality of life, and symptoms commonly associated with fatigue, which are then maintained at 15-months post-enrollment; and decreased CRP and alterations in inflammation-associated DNA methylation consistent with reduced inflammation from following the FRD as compared to the GHC.

This project seeks to determine how post-stroke cognitive impairment moderates motor learning during walking in older adults with chronic stroke and identify brain structural markers that mediate this relationship. The chosen experimental design integrates biomechanical analyses, neuropsychological assessments, and brain imaging techniques to determine the impact of post-stroke cognitive impairment severity on two forms of motor learning (explicit and implicit) and examine the role of the dorsolateral prefrontal cortex in the relationship between cognition and explicit motor learning. Ultimately, this work may lead to the development of a more comprehensive, effective treatment approach to improve walking dysfunction in older adults post-stroke.

Anxiety disorders commonly begin during adolescence, and are characterized by deficits in the ability to inhibit or extinguish pathological fear. Recent research has provided new understanding of how fear is learned and can be regulated in the adolescent brain, and how the endocannabinoid system shapes these processes; however, these advances have not yet translated into improved therapeutic outcomes for adolescents with anxiety. This study will test whether a behavioral intervention, acute exercise, can help to improve fear regulation by enhancing brain activity and endocannabinoid signaling. This line of research may ultimately lead to more effect treatments for adolescent anxiety, and to new preventive strategies for at-risk youth.

Newly released guidelines recommend increased physical activity (PA) and reduced sedentary behaviors (SB) to improve glycemia and prevent the onset and progression of type 2 diabetes (T2D). Typically, 30-60 min bouts of PA are advocated per day. Although this approach increases PA, it does not decrease the length of the sedentary periods through the day. This is important because recent epidemiological data suggest that frequently interrupting sedentary time improves glucose control even in people who achieve the recommended levels of PA. Preliminary experimental data suggest that breaking up prolonged sedentary time by performing multiple short bouts (5 min) of PA throughout the day, may improve glycemia more than performing a single continuous bout of PA, and thereby potentially be a novel strategy to prevent T2D. The improvement in glycemia was observed even when the total amount of PA and total energy expenditure were matched, suggesting that how and when PA is performed over the day may matter more than how much PA is done. However, important gaps in knowledge remain including: (1) whether similar benefits on glucose control would be observed in adults with prediabetes, a clinically relevant population that is at high risk of developing T2D; (2) whether these effects are sustained or diluted over time, and (3) what are the mechanistic underpinnings. To address these gaps, the investigators propose to measure the acute and chronic effects of PA breaks on glucose control and the underlying mechanisms in individuals at risk of developing T2D. Sedentary men and women with prediabetes (n=66, 50% F) will be randomized to either an intervention designed to interrupt SB with 5-min bouts of brisk walking performed hourly for 9 hours/day, 5 days/week (BREAK) or a control condition consisting of 45-min of brisk walking performed as a single daily continuous bout, 5 days/week (ONE). The two 3-months interventions will be matched for total active time.

Hearing aids can improve hearing, communication, and overall quality of life for people with hearing loss. However, not many people use hearing aids. A common reason is that hearing aids are expensive and hard to get. The traditional way to get hearing aids involves multiple visits to licensed audiologists for identifying hearing loss, customizing the aids, and ongoing maintenance. This traditional method is called the AUD pathway. Over-the-counter (OTC) hearing aids offer a different approach. They aim to make hearing aids more affordable and accessible, encouraging earlier use. In the OTC pathway, users diagnose their own hearing loss and fit and program the hearing aids themselves. Little is known about long-term effects of OTC hearing aids on users. This study aims to compare the experiences of people who choose the OTC pathway with those who choose the AUD pathway. It takes place in two locations: Iowa City, IA, and Nashville, TN. Participants, who have mild-to-moderate hearing loss, choose their preferred pathway and are followed for 12 months. In the OTC pathway, participants buy their hearing aids directly from OTC companies or retailers. In the AUD pathway, prescription hearing aids and fitting services are provided by audiology clinics at the University of Iowa and Vanderbilt University Medical Center. Participants are contacted 1, 6, and 12 months after starting to use their hearing aids. Researchers measure their satisfaction about hearing aids and other outcomes. If participants stop using their hearing aids, researchers assess their engagement with post-amplification hearing care. The results from both pathways are then compared.
