Eating healthy foods can help people manage health problems, like Type 2 diabetes and heart disease. Many people want to eat healthier, but changing eating behaviors is hard. Patients don't always know what foods to eat for their health problems and are hesitant to try foods that may be unfamiliar. These challenges are made more difficult when families have lower incomes, which makes accessing healthy foods difficult and trying new foods riskier when on a budget. Food is Medicine programs connect people to healthy foods that help them manage health problems. One example is a medically tailored grocery program. This program provides a patient with free groceries selected to help their medical condition. For example, a patient receives fruits, vegetables, whole grains, and low-salt, low-sugar foods if they have high blood pressure. Food resource coaching is another strategy for eating healthy food. This approach provides a coach that supports learning healthy eating habits when facing financial challenges by using available food resources. Among other strategies, a coach may teach the participant how to meal plan and shop at nearby stores to increase healthy and delicious eating patterns. In our study, the investigators will ask lower-income patients with at least one chronic health problem at a safety-net clinic if they want to participate in a Food is Medicine program. Patients that want to participate will be randomly placed in one of two groups. One group will get medically tailored groceries and food resource coaching from a free food market for four months. The other group will get free food from the same market for four months, but food will not be medically tailored, and they will not meet with a coach. Participants will have the option to continue getting food from the market at the end of the study if they want to. This study will help us learn what patients think about Food is Medicine programs and how to best carry out these programs in the future. The study will also help us determine if providing medically tailored groceries and food resource coaching helps patients improve their diet. The investigators will use what is learned in this study to create a larger and longer program that can be provided in safety-net clinics throughout Dallas-Fort Worth. Our main goal is to build a sustainable and helpful program for patients that may not otherwise have access to healthy foods and eating habits that set the foundation for better health. Read Less

This study will randomly assign 2,300 older adults on waiting lists at nine Meals on Wheels programs in Florida, Texas, North Carolina, South Carolina, and California into two groups who will receive: (a) daily delivery of meals, five days a week or (b) a shipment of 10 frozen meals, every two weeks. Researchers will examine participants' Medicare claims to understand if differences in healthcare utilization occur between the two groups within six months after they start receiving meals. Researchers will also ask participants questions prior to receiving meals, and again at three months, to understand how meals impact their ability to obtain food, their feelings of loneliness, and their overall quality of life. The primary study outcome will be the ratio of days spent in institutional settings (i.e., hospital, nursing home) in the six months after participants begin receiving meals. The secondary outcomes include the ratio of days spent in institutional settings in the three months after participants begin receiving meals, food insecurity, subjective isolation/loneliness, and health-related quality of life. The team will also examine differences in dietary intake between the two groups as an exploratory outcome. Read Less

The goal of this clinical trial study is to test if patients with idiopathic calcium oxalate kidney stones have an increased absorption of dietary oxalate, which would lead to increased urinary excretion of oxalate. The study will recruit adult patients with a history of calcium oxalate kidney stones and healthy volunteers without kidney stones. Participants will ingest fixed diets containing low and moderately high amounts of oxalate for 5 days at a time ingest a soluble form of oxalate and sugar preparations to test gut permeability collect urine, blood, stool and breath sample during the fixed diets and the soluble oxalate test Read Less

The study is investigating dysfunctions in neurocircuitry in regards to irritability with healthy controls (HC) and individuals with Major Depressive Disorder (MDD) by performing MRIs. The MDD group will also be randomized to receive ketamine or midazolam to investigate changes post-treatment in neurocircuitry with regards to irritability. Read Less

The main purpose of this study is to assess the safety and tolerability of a single dose of LY3938577 in healthy participants and participants with Type 2 Diabetes Mellitus (T2DM) (Part A) and multiple doses of LY3938577 in participants with T2DM (Part B). The study will last approximately 6 weeks for Part A and approximately 10 weeks for Part B respectively. Read Less

Chronic corticosteroid (CS) exposure is associated with changes in memory and the hippocampus in both humans and in animal models. The hippocampus has a high concentration of glucocorticoid receptors (GCRs), and the pre-clinical literature demonstrates shortening of apical dendrites in the CA3 region of the hippocampus and decreased neurogenesis in the dentate gyrus (DG) following CS administration. In humans, both stress and CS exposure are associated with a decline in declarative memory performance (a process mediated by the hippocampus). Impairment in declarative memory and hippocampal atrophy are reported in patients with excessive CS release due to Cushing's disease, and, by our group, in patients receiving prescription CS therapy. These findings have important implications for patients with mood disorders, as a large subset of people with major depressive disorder (MDD) show evidence of HPA axis activation, elevated cortisol and, importantly, resistance to the effects of CSs on both the HPA axis and on declarative memory. Thus, resistance to corticosteroids appears to be a consequence of MDD. this study will examine changes in declarative memory, as well as use state-of-the-art high-resolution multimodal neuroimaging, including structural and functional (i.e., task-based and resting state) MRI, in both men and women healthy controls, and, as an exploratory aim, a depressed group, given 3-day exposures to hydrocortisone (160 mg/day) or placebo. The study will translate preclinical findings to humans, provide valuable data on possible sex differences in the response to cortisol and, for the first time, identify specific hippocampal subfields (e.g., CA3/DG) in humans that are most sensitive to acute CS effects. Using resting state fMRI data and whole brain connectomics using graph theoretical approaches, we will determine the effects of cortisol exposure on functional brain networks. Furthermore, this will be the first study to use neuroimaging to compare the brain's response to CSs in people with depression vs. controls, and determine whether depressed people demonstrate glucocorticoid resistance within the hippocampus. We hypothesize that hippocampal response to acute CSs will be greatest in the CA3/DG subfield, greater in women than in men, and that depressed people will show a blunted hippocampal response to CSs compared to controls. A multidisciplinary research team with extensive experience in CS effects on the brain and hippocampal subfield neuroimaging, and a prior history of research collaboration, will conduct the project.

Food insecurity impacts 1 in 8 people in the United States and 1 in 4 people receiving cancer treatment. Food insecurity is associated with poor dietary quality, adverse health conditions (e.g., Type 2 diabetes, overweight and obesity, hypertension), and worse cancer treatment outcomes. To effectively address food insecurity among people with cancer, screening and effective response programs are needed. The Food to Overcome Disparities (FOOD) program screens breast cancer patients for food insecurity and refers people who screen positive to 11 clinic pantries across New York City. In addition to clinic referrals, researchers have found the addition of monthly grocery vouchers or home grocery delivery to be even more effective at improving treatment completion rates than pantry access alone. Another innovative food security strategy, nutritious no-prep, ready-to-eat meals may also be helpful for patients given that no-prep meals reduce the time and physical demand of food preparation. Nutritious no-prep, ready-to-eat meals have been positively associated with improvements in healthy eating index (HEI) scores, fewer instances of hypoglycemia, and improved quality of life among people with food insecurity that have diabetes, but has yet to be tested among patients with cancer. People receiving cancer treatment, such as infusion services, often report fatigue and other barriers to food preparation, which make no-prep, ready-to-eat meals another potential solution to cancer-specific challenges to healthy eating. In the present study the investigators will test which evidence-based strategies are most effective and well-liked by patients and will inform the development of a comprehensive food security response program at the Harold C. Simmons Comprehensive Cancer Center. Read Less

This is a cross-sectional pilot study designed to establish hot and cold cognitive functions and underlying neurocircuitry in older adults with MDD. The investigators will study 60 participants aged 21-80 years old with MDD. All participants will undergo clinical and neurocognitive assessment, and Magnetoencephalography (MEG)/Magnetic resonance imaging (MRI) procedures at one time point. The investigators will also enroll 60 demographically matched comparable, never-depressed healthy participants (controls) to establish cognitive benchmarks. Healthy controls will complete clinical and neurocognitive measures at one time point. To attain a balanced sample of adults across the lifespan, the investigators will enroll participants such that each age epoch (e.g., 21-30, 31-40, etc.) has a total of ten subjects (n=10) in both the healthy control cohort and depressed cohort.
