The minimally processed diets of our ancestors have been rapidly replaced by UPFs driving poor diet to become the leading risk factor for preventable death globally. Hence, it is essential to understand what properties of UPF are driving their overconsumption to reduce diet-related mortality. To address this gap in knowledge this proposal will test: * If UPFs have a greater post meal metabolic response when compared to MPFs an essential signal for food reward * Through the use of an auction task paradigm if UPFs overvalued and if this value is differentially encoded in the brain This study is a fully cross-over design in that each participant receives all conditions and therefore serves as their own control. All orders of foods will be counterbalanced. Although participants cannot be blinded to the conditions as they must be aware of the foods they are eating, they will not be made aware that the key manipulation is food processing. On different days participants will come to the lab and consume a meal containing either minimally or ultra-processed foods as determined by the widely used NOVA (not an acronym) scale. These conditions will be consumed in a whole room metabolic chamber allowing for simultaneous measurement of multiple metabolic responses (glucose, insulin, and metabolic rate). These measures will be collected for 45 min before consumption of the meal (baseline) and for 3 hours after consumption (post-prandial). All participants will also undergo a Becker-Degroot-Marschak auction paradigm that consists of foods that are either minimally or Ultra-processed in the MRI scanner. Food value will be measure in participants' willingness to pay for each food and Neural responses will be measured during presentation of the food cues. Read Less

Dietary factors contributed to nearly 50% of all cardiometabolic deaths in the US in 2012, making it one of the leading causes of preventable death in the US, second only to tobacco use. Human diets and food choices can't help but be influenced by the ubiquitous availability of processed foods of high-energy density and low nutrient content, consumption of which can lead to obesity, type II diabetes, heart disease, and other types of metabolic dysfunction. Surprisingly, food reinforcement does not rely on perceived energy density. Rather food reinforcement is associated with actual energy density and therefore, on an implicit knowledge of caloric content. That implicit knowledge must have a neural signature and a mechanism by which the gut communicates nutritive value to the brain. There is evidence, at least for fat and carbohydrates, that these pathways are separable, but terminate in a common neural structure, the dorsal striatum or caudate. This could be one mechanism by which modern processed foods high in both fat and carbohydrate are so sought after and readily consumed, In fact, when experimentally tested, fat and carbohydrate combinations were more reinforcing calorie for calorie than fat or carbohydrates alone and the level of reinforcement correlated with activity in reward- related brain areas. Beyond simple reinforcing value, it is known from the literature on drugs of abuse that the faster a drug is arrives at the brain, the higher it's abuse potential, however, little is known about how the kinetics of nutrient excursion influence food preference, choice, and brain activity. This project aims to test this specifically for carbohydrate reward. Read Less

The goal of this study is to determine the effectiveness and sustainability of a community-participatory hydration intervention over 3 years within a district that has newly installed hydration stations and is operating under a policy designed to enhance heathy hydration practices and promote equitable access to drinking water.

The overall aim of the proposed project is to develop and evaluate the effectiveness of Brief Violence Intervention-Virtual Reality (BVI-VR) for reducing firearm-related violence, re-injury, and mortality among victims of violence. Outcome measures of firearm-related violence will come from multiple sources, including criminal background checks, hospital data, state-level data, semi-structured clinical assessments, and self-report assessments. In addition, the study aims to understand the impact of BVI-VR on psychosocial mediators resulting in a reduction of firearm-related violence. This will include self-report surveys, neurocognitive assessments, and clinical assessments. The economic efficiency of BVI-VR as a firearm-related violence intervention will also evaluated. To achieve these aims, a randomized control trial (RCT) in a large sample of violently injured adults (18+ years) from VCU Health will be conducted. Read Less

The goal of this clinical trial is to compare casts with cast art versus those without art in children who sustain a fracture of the extremity. The main goals are: * Determine the difference in satisfaction as measured by the visual analog scale for satisfaction between patients treated in a cast with cast customization versus those in a cast with no cast art * Determine the difference in perceived pain scores between patients treated in a cast with cast customization versus those in a case with no cast art Participants will be randomized to one of three groups: one with plain white cast, one with cast of color wrap of choice, and one with custom cast art. Researchers will compare to see the differences in satisfaction and perception of pain based on what cast the study participant receives. Read Less

Neonates delivered by scheduled Cesarean Section will be randomized to receive vaginal seeding (exposing the infant to Mother's vaginal flora) or sham. Infants will be followed for three years to examine health outcomes including microbiome development, immune development, metabolic outcomes, and any adverse events. Read Less

Study aims to examine the effects of noninvasive brain stimulation on brain signals. This insight may have potential clinical implications for addiction, pain, and mental health populations. Participants will receive MRI and CT imaging. Participants receive low-intensity focused ultrasound (LIFU) to temporarily change brain activity. Participants then receive fMRI scans to measure changes in both resting and heat evoked brain signaling using a quantitative sensory testing device. Heart rate, blood pressure, respiratory rate, and skin moisture is monitored. Participants complete a battery of questionnaires, both behavioral and symptom monitoring. The study takes place over 4 study visits. Read Less

This study is trying to find out whether performing a hybrid aerobic-resistance exercise training program (titled PRIME: Peripheral Remodeling via Intermittent Muscular Exercise) results in better health outcomes than the traditional exercise training program (called COMBO) that is used in individuals with heart failure with reduced ejection fraction (HFrEF). Participants will be randomized (like the flip of a coin) to either PRIME (investigational) or the traditional exercise program (standard of care). Read Less

Research has shown that for women who are undergoing pelvic radiation therapy, fatigue is a common side effect. Fatigue that occurs during radiation therapy can make it harder to perform daily living activities. While there are studies that recommend exercise as a treatment for fatigue in cancer patients and survivors, there are currently no studies that focus on the role of exercise for women undergoing pelvic radiation therapy. The purpose of this study is to see if incorporating an activity coaching program is helpful in improving treatment-related fatigue for women undergoing pelvic radiation therapy for endometrial cancer.

Patients with HAE Type I or II who enroll in the study are asked to complete a patient diary when they experience an HAE attack. If icatibant is taken as the first treatment for the attack, the patient diary will ask questions over a 48 hour period after dosing to track the characteristics and severity of the attack along with the patient's level of anxiety.

The goal of this clinical trial is to evaluate whether our transitional care program helps stroke survivors better manage their risk factors for stroke to lower the risk of a repeat stroke. The main question it aims to answer is: - Does the program help participants meet the targets set by the American Heart Association clinical guidelines for control of risk factors associated with stroke? Researchers will compare participants enrolled right after being discharged from the hospital to participants enrolled around 3-5 months after being discharged to examine whether timing differences in enrollment affect the efficacy of the program. Participants will: * Keep track of their medications, their exercise, and their health information using smart devices provided by the study * Answer questions about their health and lifestyle * Meet with our team of healthcare providers Read Less
