This study will investigate the effects of 15 minutes of massage compared to 15 minutes of quiet rest on physiological variables. Specifically, the investigators will measure the effects on levels of the social hormone oxytocin, and on other physiological variables that interact with oxytocin or that may be influenced by massage (including ACTH, Beta-endorphin, and IL-1alpha). The investigators will also investigate whether, in the case of hormones changes, these influence social decision making.
This study will look at whether motivational sessions (including regular calls with a trained health coach) in combination with time-restricted eating (TRE) is an effective way to achieve weight loss and lower cardiometabolic risk in adult survivors of childhood cancer. We will look at how effective this intervention is compared to the usual approach, which is to review educational materials and measure weight once a month. This study will not provide treatment for any disease or cancer.
Our goal is to observational study is to determine feasibility of partial sleep restriction in individuals with CLBP+I and correlation findings with features of central sensitization. * Identify feasibility of sleep restriction protocol * Identify correlation between less sleep and central sensitization Sleep will be monitored for 2 weeks (baseline sleep monitoring period). Then participants will be asked to restrict their sleep to 80% of their normal sleep duration for 5 nights (sleep restriction period). Then sleep will be monitored again for 2 weeks (sleep recovery period).
The primary purpose of this study is to measure pulmonary function, symptoms, and pulmonary inflammatory responses in healthy young adults during and immediately after exposure to a low concentration of ozone (0.070 ppm) or clean air for 6.6 hours while at rest. This concentration is the current EPA NAAQS standard for ozone.

The goal of this randomized controlled trial is to assess recovery in patients undergoing benign laparoscopic gynecologic surgery. The main question it aims to answer is: do liberalized postoperative restrictions improve patient recovery after laparoscopic gynecologic surgery? Researchers will compare postoperative recovery surveys from the control group (patients given standard postoperative restrictions limiting activity for 2 weeks) to the research group (patients given liberalized postoperative instructions allowing them to engage in their normal activities of daily life at their own discretion without prescribed activity restrictions) to see if liberalized postoperative restrictions improve the recovery experience. Participants will be asked to fill out a brief questionnaire at two time intervals, 1 week after surgery and 2 weeks after surgery.
Recovery of arm and hand motor control is critical for independence and quality of life following incomplete spinal cord injury (iSCI). Blood flow-restricted resistance exercise (BFRE) has emerged as a potential treatment addressing this need, but treatment guidelines and research reporting effectiveness are sparse. The purpose of this work is to provide case reports of people with cervical iSCI who use BFRE supplemented by electrical stimulation (ES) to increase the strength and functional use of selected upper extremity muscles.
The goal of this observational study is to learn what can predict the return of the sense of smell in patients with chronic rhinosinusitis with nasal polyps being treated with dupilumab. The main questions it aims to answer are: 1. Does obstruction of the olfactory cleft predict return of the sense of smell? 2. Do electrophysiological signals generated by breathing and sniffing behavior predict return of the sense of smell? Participants starting dupilumab will undergo assessment for their degree of olfactory cleft obstruction, and an electrophysiologic assessment of their olfactory cleft and be followed over 6 months of treatment with dupilumab.
Time-restricted feeding limits caloric intake to active daytime hours with fasting for 14 to 16 hours. It has shown great promise as a novel intervention for stabilizing blood glucose, reducing weight, and improving cardiovascular disease outcomes. However, this approach has not been tested on people with diabetes, a group that would benefit from improved blood glucose and weight loss. The impact of Time-Restricted Eating on Type 2 Diabetes Study (EaT2D Study) is a randomized six-day weight stable crossover feeding study in the Day Patient/Outpatient unit of The Rockefeller Hospital investigating how the time of day that meals are eaten affects weight, blood sugar and blood pressure. The investigators will compare an early time-restricted eating intervention (80% of calories consumed before 2 pm) to a usual feeding pattern (50% of calories consumed after 4 pm) among 10 persons with type 2 diabetes to determine effects on blood sugar and small molecules found in the blood. Studies have shown benefits of eating during active periods (mornings and early afternoon) for metabolic health (blood sugar, body weight) compared to eating during inactive periods (evening and bedtime). Eating earlier in the day may lead to reduced sugar stores, burning fat for energy, and decreased inflammation when compared to eating later in the day. The investigators will compare the effects of eating earlier during the day for six days versus later in the day for six days, on blood sugar, blood pressure, blood ketones, and other measures of metabolic health in diabetic participants. Studies in animals supports these benefits.
This is a clinical trial to assess how time-restricted eating (TRE) may improve kidney health and filtration patients with type 2 diabetes and increased protein content in their urine. All participants will be participating in TRE in which they follow a consistent 8-10 hour eating window everyday.
The goal of this pilot randomized controlled trial is to test the feasibility, acceptability, and preliminary signal of effect of a combined school- and home-based sleep promotion program for young children prior to the kindergarten transition.
This research will explore if brain stimulation combined with virtual reality therapy improves visual impairment. The stimulation technique is called low-intensity focused ultrasound stimulation (LIFUS). The treatment uses ultrasound to stimulate vision specific parts of the brain. Before this therapy, the participants will get structural brain imaging. Functional brain imaging will be performed before and after the study's completion to measure brain activity response to therapy. The purpose of this research study is to evaluate patients who have had a stroke between 6 and 24 months ago with a visual field impairment. The duration of active participation in the study is 1.5 months.
Unhealthy diets significantly contribute to preventable chronic diseases among older adults. To advance the investigator's understanding of policies needed to support healthy diets, the objectives are: 1) to develop and validate an online fast food restaurant ordering application; and 2) to conduct a feasibility study for a larger randomized, controlled trial that will test healthy food policies in restaurant settings.
This research study aims to explore whether a set of simple breathing techniques and guided meditations can improve the psychological well-being and recovery of ICU survivors and their caregivers. ICU survivors and their caregivers often experience high levels of stress, anxiety, and depression after discharge. This study investigates whether practicing Isha Kriya, a guided meditation, and Nadi Shuddhi, a breathing technique, can support their mental health and relationship quality. These practices are delivered through a mobile app or in a group setting. Participants enroll as a caregiver-patient dyad and will engage in these techniques throughout the study. In addition to the practices, brain activity will be recorded using a safe, non-invasive EEG device. The EEG, a lightweight cap with small sensors, measures brainwaves to assess potential changes in brain function and connection. EEG recordings will take place in the hospital during two sessions, each lasting approximately 40 minutes. Participants will also complete short surveys at five time points throughout the study, assessing mood, stress, and relationship quality. Baseline demographic information will be collected, and at the conclusion of the study, a brief interview will be conducted to gather feedback on the experience. The study spans approximately seven weeks, with the overall goal of determining whether these breathing and meditation practices can provide accessible and scalable mental health support for ICU survivors and their caregivers.
This study assesses the tolerability, safety, and impact of an investigational medical device on restless legs syndrome symptoms. The IRB has established that the investigational device is non-significant risk.
This pilot randomize trial tests the feasibility of administering two different exercise programs in people with knee osteoarthritis. One group receives the exercise program administered as usual, and the other group received the exercise program with resting intervals.
The presence of certain ingredients such as sodium and glycerol can facilitate retention of the fluid consumed via renal water reabsorption. To maintain overall whole-body fluid balance, it is important that ingested fluid is retained in the body instead of losing it through urination. The purpose of this study is to determine the effect of sodium and glycerol concentrations at various fluid intake volumes on fluid balance in healthy, euhydrated men and women.
The purpose of this research study is to better understand optimal restrictions for patients postoperatively following a mesh urethral sling placement for patients with stress urinary incontinence. Patients undergoing a midurethral sling procedure will be assigned to one of two groups. One group with be given standard postprocedural restrictions including instructions to avoid moderate activity and no lifting over 15lbs for six weeks after surgery. The other group will have fewer restrictions, with no restrictions on activity or lifting. Participants will complete surveys at 2 weeks, 3 months and 1 year following their procedure to help providers better understand how patients are following postoperative restrictions and if there were any differences in the outcome of the procedure between the two groups.
This randomized clinical trial (RCT) evaluates whether metformin can reduce systemic inflammation and improve immune function in individuals with a history of injection drug use, with or without HIV. Participants will receive metformin or placebo and undergo immune system assessments, including vaccine response evaluations.
This is a feasibility study that will collect data to assess the potential effect of a nutritional intervention designed to improve liver metabolism. This prospective single-site trial will enroll adult patients undergoing liver-directed therapies for hepatocellular carcinoma. Eligible individuals who are randomized to the intervention group will be enrolled in a six-month nutritional change program consisting of time-restricted eating in which calorie consumption is limited to 8-10 hours during the day, plus targeted healthy changes in what they eat. The intervention includes dietary counseling visits with a study registered dietitian and motivational phone calls with a study Certified Health and Wellness Coach to help subjects adhere to the intervention. Individuals in the control group will be enrolled in a six-month period of observation only. The main questions it aims to answer are: Is a prolonged nightly fast coupled with a healthy diet safe and feasible for patients with liver cancer? Does the intervention improve liver metabolism?
Both BFR and intermittent pneumatic compression are purported to decrease symptoms associated with exercise induced muscle damage (EIMD) that cause delayed onset muscle soreness (DOMS). Blood flow restriction relies on applying pressurized cuffs to the most proximal portion of the limb. Another form of recovery often relied upon is pneumatic compression. The mechanism by which pneumatic compression works is similar to that of a massage, whereby the device progressively increases the pressure on a portion of the limb before releasing and moving further up the limb.The purpose of this study is determine whether BFR or pneumatic compression can be used to decreased DOMS which may indicate enhanced recovery.
This is a study to evaluate the efficacy, safety, and tolerability of BMS-986368, a FAAH/MAGL inhibitor, for the treatment of agitation in participants with Alzheimer's Disease.
The purpose of this research is to compare the performance of acceleromyograph and electromyograph-based quantitative neuromuscular monitors when the arms are tucked for surgical positioning.
The goal of this clinical trial is to test meal-timing as a novel and sustainable interventional approach during cancer treatment to improve therapeutic response and metabolic health in an understudied population. This clinical trial will enroll patients with rectal cancer receiving neoadjuvant treatment at the Alaska Native Medical Center (ANMC), which is part of the Alaska Native Tribal Health Consortium (ANTHC). A promising strategy for improving the efficacy of anticancer treatments and reducing associated toxicities involves combining treatment with fasting regimens. In pre-clinical and clinical studies, various forms of fasting have been shown to induce tumor regression and improve long-term survival. According to the differential stress sensitization theory, fasting is thought to sensitize tumor cells to the cytotoxic effects of chemotherapy and radiation, while protecting healthy cells by increasing stress resistance. While healthy cells slow their growth and become more stress resistant in response to fasting, cancer cells cannot survive in nutrient-deficient environments; although the underlying mechanisms are not fully understood. However, extended water-only fasting can be challenging for patients and poses undue health risks. Intermittent fasting, and specifically time-restricted eating (TRE), may offer a viable alternative. TRE involves eating within a shorter window (e.g., 8 hours) and fasting for the remainder of the day but involves no other dietary restrictions. Because of its simplicity, TRE may be more sustainable than other fasting regimens. TRE also improves several cardio-metabolic endpoints, including insulin sensitivity, which may also be beneficial during anticancer treatments.
Consuming a carbohydrate-rich food as the final food in a meal, as compared to the first food in a meal, has been shown to reduce blood glucose levels after eating in both diabetes patients and in healthy controls. However, gaps remain in the literature in this area of research, and currently little is known about how substrate (fuel) use is impacted by altering food order. In addition, most studies to date have used a mix of meat and plant foods, while little research has focused exclusively on vegetarian foods. This randomized experiment will examine how altering the order of foods eaten in a vegetarian meal impacts blood glucose and fuel utilization at rest.
The purpose of this study is to investigate the use of single (SC) and multi-chamber (MC) blood flow restriction (BFR) cuff bicep exercise on indices of arterial stiffness, muscle morphology, and participant perception.
Patients undergoing surgery with the Walter Reed National Military Medical Center Urogynecology Clinic will be randomized to either standard opioid prescribing or restricted opioid prescribing. They will be surveyed on their satisfaction with their postoperative pain control and their pain levels and opioid use will be tracked postoperatively.
The study aims to observe changes in dopaminergic genes expression in peripheral tissue upon prolonged dopamine agonist treatment on patients with Restless Legs Syndrome (RLS). Similar studies in Parkinson's disease have shown changes in alpha-synuclein expression, which might offer insights into the dopaminergic gene regulation seen in RLS. The dopamine agonist drugs to be included in this study are: Pramipexole (Mirapex), Ropinirole (Requip), Rotigotine (Neupro), Apomorphine (Apokyn), Bromocriptine (Parlodel). Specifically, the study will collect nasal swabs of participants partitioned into two groups, those who have not used a dopamine agonist or been on a dopamine agonist for less than 1 month compared to those who have been on the medication for 6 or more months. This research could provide insight into changes in dopaminergic gene expression associated with Augmentation Syndrome (AS) which occurs after long term dopamine agonist treatment in RLS patients.
This study is being done to learn more about energy needs and muscle function during treatment for bladder cancer. These insights can help improve future patient care. The study team found in a previous study that resting energy can be different than what estimates show. Patients with bladder cancer are known to suffer a decline in physical resilience over time. Monitoring patients to understand these changes better could help design future treatments with these vulnerabilities in mind.
