This research study is being done to investigate if the GH Method exercise program positively affects body composition, improves physical abilities and can improve the overall sense of wellbeing (e.g. depression, PTSD, etc.) in U.S. Veterans. Subjects will be asked to complete 94 total visits (four (4) study testing visits and 90 exercise visits). Enrolled subjects will be tested for fitness, strength, and health risk factors at UIC 4 times and will complete 90 exercise training visits at the GH FITLab over the next 18 months. Subjects will also be asked to complete questionnaires about depression, post-traumatic stress symptoms and thoughts about harming oneself. Read Less

Intermittent energy restriction (IER) may have important advantages over daily energy restriction (DER) in producing sustained weight loss and reducing cancer risk. IER is already being promoted with limited evidence, thus, additional evidence is urgently needed from rigorously conducted clinical trials. IER has been proposed to invoke a greater metabolic shift to fat metabolism than DER and preferentially reduce central obesity. The Investigators adapted the IER and the Mediterranean diet (MED) approach which have been recommended as a healthy weight-loss diet in the management of non-alcoholic fatty liver disease, for an ethnically diverse population. The effectiveness was compared to an active comparator (DASH diet) in reducing overall and visceral adiposity in a randomized trial among 60 middle-aged adults with visceral obesity. This 12-week pilot demonstrated the feasibility and safety of IER and the culturally-adapted MED \[NCT03639350\]. The six-month randomized trial will demonstrate the superiority of IER over DER in reducing fat and total fat mass, and in improving cancer-related biomarkers and gut microbiome functions. This longer trial, to confirm safety and superiority of IER over DER in reducing VAT and liver fat will expand our understanding of adherence to IER and its effect on the gut microbiome as a possible mediator of systemic inflammation. The Investigators will conduct a 24-week randomized trial of IER+MED vs. MED/DER among 260 middle-aged adults of East-Asian, Native Hawaiian and other Pacific Islanders or White ethnicity with high VAT. The primary research question is whether a diet plan combining IER and the MED dietary pattern will be superior to MED/DER in reducing abdominal MRI-measured visceral and liver fat and dual-energy X-ray absorptiometry (DXA) measured total adiposity. The Healthy Diet and Lifestyle Study II (HDLS2) will recruit 312 men and women from the general population with VAT at or above the population-median (men: ≥90 cm2; women ≥80 cm2) and randomize them to the IER+MED or MED/DER diet (156 per group). The IER+MED group will follow IER for two consecutive days (70% energy restriction) and total energy MED diet for the other five days of the week, reaching an overall 20% energy restriction. The MED/DER group will be prescribed a 20% daily energy restriction. With an expected attrition rate of \~16% (10% in Pilot), the investigators expect 130 participants per group to complete the study. Read Less

Youth represent the largest proportion of new HIV infections in Colorado, reflective of their inadequate access and uptake of pre-exposure prophylaxis(PrEP)for HIV prevention. Colorado's 2019 HIV/AIDS Prevention Program state-wide review of PrEP barriers showed PrEP eligible individuals do not access PrEP services due to lack of interest, not wanting referral to a navigator, and low estimation of HIV risk. The overall goal is to provide youth at higher risk for HIV with an effective youth informed telemedicine delivery of PrEP (TelePrEP) that addresses PrEP barriers and contributes to ending the HIV epidemic in Colorado. The primary objective will be proportion of youth retained on PrEP 12 months after initiation. The hypotheses are that a TelePrEP model for youth will be acceptable and feasible and will result in successful initiation, persistence and retention on oral PrEP. Read Less

This clinical trial will be a comparison between personalized recommended caffeine dosing regimen versus the standard recommended caffeine dosing regimen for sustaining performance during sleep deprivation and minimizing side effects and subsequent sleep disruption. The questions this study aims to answer are: Whether the personalized caffeine recommendations improve vigilance, sleepiness, and cognition after total sleep deprivation, compared to standard recommendations; Whether the personalized caffeine recommendation better addresses the physical and emotional side effects of total sleep deprivation, compared to standard recommendations; And whether personalized caffeine recommendations aids in better recovery sleep after total sleep deprivation, compared to standard recommendations. Participants will be asked to: 1. Complete a 13-day at-home portion, wearing an actigraph watch to measure activity and sleep, and complete motor vigilance tests up to six times a day. 2. Complete a 4-day in-lab portion, where participants will have to complete one night of baseline sleep, undergo 62-hours of total sleep deprivation, and then complete one night of recovery sleep. 3. During the in-lab portion of the study, participants will be asked to complete more motor vigilance tests. Researchers will be comparing the personalized caffeine recommendation group against the standard caffeine recommendation to see if it is better at addressing each of the main questions. Read Less

The objective of the study is to compare supplementation with vitamin D at 800 IU/day to usual care for the first 28 days after birth with respect to 25 (OH) vitamin D levels and indicators of likely or plausible effects of vitamin D supplementation on the function or structure of the lung, bones, immune system, and brain in extremely premature (EP) infants who are \<28 weeks gestational age (GA) or \<1000 grams of birth weight (BW). The study results will be analyzed as intention to treat Bayesian analyses (Frequentist analyses will also be performed). Read Less

The University of California Davis, Comprehensive Cancer Center's (UCDCCC) Office of Community Outreach and Engagement (OCOE) serves the 19 catchment counties which approximately consists of 5 million residents. Currently, the overall catchment population cancer screening rates fall below 80%. The aim of OCOE is to increase cancer education (prevention, screening, and vaccination) and training. Through education, and encouraging participation in routine screening for early detection, this can help increase cancer knowledge. In addition to cancer education, OCOE wants to educate community members regarding modifiable risk factors which include tobacco usage, being overweight/obese (physical inactivity/poor nutrition), and lack of immunizations. By increasing knowledge of cancer prevention, screening, and vaccination this will help community members become more aware of their cancer risk. Read Less

The SKyRoCKeT Study (Surface-Knit and Reformulate CADENCE-Kids for Translation) will recruit a sex- and age-balanced sample of 360 young people 6-20 years of age to develop an integrative, physiologically-coherent age-cadence-log(metabolic equivalent, MET) surface-based model, reformulate the prior R21 CADENCE-Kids study (1; NCT01989104) by providing individualized, more precise, age-specific and coherent cadence-intensity thresholds, investigate additional differences by anthropometric factors, and translate cadence-intensity thresholds to over-ground walking. The SKyRoCKeT Study is an innovative critical step to provide a coherent, interpretable, objectively monitored step-based intensity metric to inform (inter)national physical activity (PA) guidelines by transforming currently vague guidelines of PA intensity into quantifiable PA recommendations that can be of widespread use, which clinicians, young people, parents, and researchers can integrate into preventive care management and action plans for personalized care. The SKyRoCKeT Study will allow for a user-friendly, interpretable metric to more accurately inform public health/behavioral interventions, assessments, analyses, school-based health and physical education curricula and programs, and public health messages for young people and their caregivers.

Small bowel obstruction (SBO) is one of the most common causes of serious gastrointestinal disease in the US. Adhesion-related SBO (aSBO) is usually treated by the placement of a nasogastric tube (NGT) to decompress the stomach, administration of intravenous (IV) fluids and observation by a surgical team. The purpose of this feasibility study is to determine the potential for implementation of treatment protocols for aSBO and determine the feasibility of randomizing patients with aSBO to receive or not receive NGTs or water-soluble contrast (WSC). The investigators will also determine the ability to measure HRQOL as a main outcome for the treatment of aSBO. The studies outlined in this research program intend to address gaps in knowledge about how to determine who benefits from NGT placement, who can be managed without them, how to objectively determine when a bowel obstruction has resolved, how to reintroduce feeding to patients with aSBO, what criteria should be used for hospital discharge and what role cathartics such as WSC contrast have in the management of aSBO. This feasibility study will enroll a limited number of patients (n=40) who will be followed for up to 30 days. Read Less
