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

Esophageal cancer is a deadly disease that is becoming increasingly common in the United States. Barrett's esophagus (BE) is a pre-cancerous state that can develop into esophageal cancer, but is highly treatable. Progression of BE to esophageal cancer is still common due to missed diagnosis of Barrett's esophagus recurrence following treatment. Wide-Area Trans-Epithelial Sampling (WATS-3D) is a new technology that uses brush sampling to examine larger areas of the esophagus as compared to conventional biopsies. Preliminary studies show improved detection of cancerous changes in Barrett's esophagus surveillance. The investigators hope to see if the addition of WATS-3D increases the rate of detection of recurrent BE following treatment, which is of the utmost importance since it would allow for earlier re-treatment of disease and ultimately allow for prevention of progression to esophageal cancer.

The goal of this intervention study is to learn about how weight loss impacts molecular signaling of intermuscular adipose tissue (IMAT) in individuals with obesity. The main question it aims to answer is how inflammatory molecules secreted by IMAT promote muscle insulin resistance and inflammation, and how these same molecules are diminished after weight loss. Following screening visits involving body composition measures, blood testing, strength testing, and a thigh muscle biopsy, participants will go through a 12-week dietary intervention for weight loss. After 12 weeks, this will be followed by the same testing and biopsies that were completed before the intervention. Researchers will then compare outcomes of individuals who lost weight to individuals who did not lose weight. Read Less

The Pediatric Dose Optimization for Seizures in Emergency Medical Services (PediDOSE) study is designed to improve how paramedics treat seizures in children on ambulances. Seizures are one of the most common reasons why people call an ambulance for a child, and paramedics typically administer midazolam to stop the seizure. One-third of children with active seizures on ambulances arrive at emergency departments still seizing. Prior research suggests that seizures on ambulances continue due to under-dosing and delayed delivery of medication. Under-dosing happens when calculation errors occur, and delayed medication delivery occurs due to the time required for dose calculation and placement of an intravenous line to give the medication. Seizures stop quickly when standardized medication doses are given as a muscular injection or a nasal spray. This research has primarily been done in adults, and evidence is needed to determine if this is effective and safe in children. PediDOSE optimizes how paramedics choose the midazolam dose by eliminating calculations and making the dose age-based. This study involves changing the seizure treatment protocols for ambulance services in 20 different cities, in a staggered and randomly-assigned manner. One aim of PediDOSE is to determine if using age to select one of four standardized doses of midazolam and giving it as a muscular injection or nasal spray is more effective than the current calculation-based method, as measured by the number of children arriving at emergency departments still seizing. The investigators believe that a standardized seizure protocol with age-based doses is more effective than current practice. Another aim of PediDOSE is to determine if a standardized seizure protocol with age-based doses is just as safe as current practice, since either ongoing seizures or receiving too much midazolam can interfere with breathing. The investigators believe that a standardized seizure protocol with age-based doses is just as safe as current practice, since the seizures may stop faster and these doses are safely used in children in other healthcare settings. If this study demonstrates that standardized, age-based midazolam dosing is equally safe and more effective in comparison to current practice, the potential impact of this study is a shift in the treatment of pediatric seizures that can be easily implemented in ambulance services across the United States and in other parts of the world.

GALAXY is a registry research study that plans to learn more about individuals with X\&Y variations (also called sex chromosome aneuploidies) through collecting information from medical records.This includes genetic tests, imaging, medications, and more for hundreds of patients seen at a number of clinics across the US. The purpose of the GALAXY Registry is to collect and store this information with the overall goal to improve health outcomes in individuals with X\&Y variations and the care they receive. Read Less

This is a prospective, observational, multi-center cohort study of pediatric cardiac arrests. The purpose of the study is to determine the association between chest compression mechanics (rate, depth, flow fraction, compression release) and patient outcomes. In addition, the investigators will determine the association of post cardiac arrest care with patient outcomes. Read Less

The purpose of this study is to compare the effectiveness and safety of a strategy of switching to an alternative targeted immunomodulator (TIM) therapy to treat to a target of endoscopic remission, versus continuing index TIM in patients with inflammatory bowel disease (IBD) (Crohn's disease or ulcerative colitis \[UC\]) in symptomatic remission with moderate to severe endoscopic inflammation despite optimization of index TIM in a real-world setting.

Risk of cardiovascular diseases (CVD) is significantly elevated in patients with chronic kidney disease (CKD); however, this increased risk is only partially explained by traditional CV risk factors. Arterial dysfunction is an important nontraditional CV risk factor gaining increased recognition in the field of nephrology. This process is best represented, both physiologically and pathophysiologically, by increases in the gold standard measure of arterial stiffening, carotid to femoral artery pulse wave velocity (CFPWV), which reflects, in particular, increases in aortic stiffness. Aortic stiffening with CKD is mediated by structural and functional (increased vascular smooth muscle tone) changes in the arterial wall stimulated by oxidative stress and chronic low-grade inflammation. Caloric restriction (CR) is a promising strategy for prevention of CKD-associated arterial dysfunction and CVD. However, long-term adherence to chronic CR regimens with optimal nutrition is very difficult to achieve. Research has shown that boosting NAD+ bioavailability to stimulate SIRT-1, a "CR mimetic" approach, reduces CFPW and oxidative stress in old mice, and this lab recently took the first step in translating these findings in a study of adults with normal kidney function and elevated systolic blood pressure (SBP). The data found that supplementation with nicotinamide riboside, a natural, commercially available precursor of NAD+ and novel CR mimetic, increased NAD+ bioavailability and reduced CFPWV and SBP. A randomized, placebo-controlled, double-blind, single-site phase IIa clinical trial to assess the safety and efficacy of oral nicotinamide riboside (500 mg capsules 2x/day; NIAGEN®; ChromaDex Inc.) for 3 months vs. placebo for decreasing aortic stiffness and SBP in patients (35-80 years) with stage III and IV CKD is being proposed. It is hypothesized that treatment will reduce CFPWV and SBP, as related to increases in systemic NAD+ bioavailability and reductions in oxidative stress, and inflammation. Aim 1: To measure CFPWV (primary outcome) before/after nicotinamide riboside vs. placebo treatment; Aim 2: To measure casual and 24h-ambulatory SBP (secondary outcome) before and after treatment; Aim 3: To determine the safety and tolerability of treatment with nicotinamide riboside vs. placebo; Aim 4: To measure systemic NAD+ and NAD+-related metabolite concentrations, as well as circulating markers of oxidative stress, inflammation, and vasoconstriction factors before and after treatment.

Diabetic kidney disease (DKD) occurs in up to 40% of people with type 1 diabetes (T1D), often leading to kidney failure and markedly magnifying risks of cardiovascular disease and premature death. Landmark T1D kidney biopsy studies identified the classic pathological lesions of DKD, which have been attributed largely to hyperglycemia. Recent advances in continuous glucose monitoring (CGM) and automated insulin delivery have facilitated improved glycemic control, but the residual risk of DKD continues to be high. In addition, obesity and insulin resistance (IR) have accompanied intensive glycemic therapy and may promote mitochondrial dysfunction and inflammation. Deciphering the molecular underpinnings of DKD in modern-day T1D and identifying modifiable risk factors could lead to more effective and targeted therapies to prevent DKD. Read Less
