Our UH3 clinical trial, "Reducing Asthma Attacks in Disadvantaged School Children with Asthma," seeks broad-scale implementation of our effective school-based approach to improve asthma disparities for children, ages 5-12 years, in low-income communities. The investigators will contextualize dissemination and implementation (D\&I) of our Colorado school-based asthma program (Col-SBAP) that reduces asthma exacerbations and missed school days, while also addressing social determinants of health. Our Better Asthma Control for Kids (BACK) Program will evaluate key metrics identified by diverse stakeholders during this dissemination trial in rural and small metropolitan areas of Colorado. Our clinical trial includes two implementation strategies: our standard Col-SBAP, titled BACK-Standard (BACK-S) and an enhanced community-centered approach, titled Back-Enhanced (BACK-E). These two strategies are designed for sustainable delivery by school asthma navigators and school nurses who coordinate with primary care and community resources. The Exploration, Preparation, Implementation, Sustainment (EPIS) D\&I framework was applied with community partners during the UG3 planning phase to tailor implementation plans that meet local community needs, resources and priorities (EPIS Phases 1 \& 2). BACK-S and BACK-E will be delivered from years 1-3 with data collection for implementation and effectiveness outcomes in 4 Colorado regions. In year 4, the investigators will collect data for sustainment outcomes (EPIS phase 3). The investigators will apply the work from EPIS phases 1-3 to refine our "dissemination playbook" that guides adoption by other school systems (EPIS Phase 4). Our primary implementation hypothesis is: Reach will be greater among students when delivered using the BACK-E arm as compared to BACK-S. Our effectiveness hypothesis is: BACK will be more effective than usual care at reducing asthma exacerbations. The BACK playbook includes training materials and a calculation of return on investment. The investigators are targeting schools with high levels of uncontrolled asthma and asthma associated burden. Our UH3 trial includes partner engagement to ensure BACK is disseminated to diverse geopolitical areas of Colorado with attention to sustainability. Collectively, our approach will accelerate dissemination of BACK nationally to communities experiencing health inequities in pediatric asthma care. Read Less

The purpose of this research study is to learn about the best approach to sample patients with known or suspected Barrett's esophagus (BE) by comparing the standard Seattle biopsy protocol to sampling using wide area transepithelial sampling (WATS3D). Barrett's esophagus is a common condition that is used to spot patients at increased risk of developing a type of cancer in the esophagus (swallowing tube) called esophageal adenocarcinoma. The 5-year survival rate is as low as 18% for patients who get esophageal adenocarcinoma, but the rate may be improved if the cancer is caught in its early stages. Barrett's esophagus can lead to dysplasia, or precancerous changes, which occurs when cells look abnormal but have not developed into cancer. If the abnormal cells increase from being slightly abnormal (low-grade dysplasia), to being very abnormal (high-grade dysplasia), the risk of developing cancer (esophageal adenocarcinoma) goes up. Therefore, catching dysplasia early is very important to prevent cancer. Endoscopic surveillance is a type of procedure where endoscopists run a tube with a light and a camera on the end of it down a patients throat and remove a small piece of tissue. The piece of tissue, called a biopsy, is about the size of the tip of a ball-point pen and is checked for abnormal cells and cancer cells. Patients are being asked to be in this research study because they have been diagnosed with BE or suspected to have BE, and will need an esophagogastroduodenoscopy (EGD). Patients with BE undergo sampling using the Seattle biopsy protocol during which samples are obtained from the BE in a four quadrant fashion every 2 cm along with target biopsies from any abnormal areas within the BE. Another sampling approach is WATS3D which utilizes brushings from the BE. While both of these procedures are widely accepted approaches to sampling patients with BE during endoscopy, there is not enough research to show if one is better than the other. Participants in this study will undergo sampling of the BE using both approaches (Seattle biopsy protocol and WATS-3D); the order of the techniques will be randomized. Up to 2700 participants will take part in this research. This is a multicenter study involving several academic, community and private hospitals around the country. Read Less

Pregnancy elicits adaptive changes in uteroplacental blood flow, which are altered at high altitude and may contribute to the observed 3-fold increase in intrauterine growth restriction (IUGR) and preeclampsia (PreE). The investigators propose to collect myometrial, cord blood, and placental tissue samples from women at high altitude (Summit County) and low altitude (Denver) in Colorado in order to determine if residence at altitude during pregnancy changes the vasoreactivity of myometrial arteries (MA). If altered MA vasoreactivity is found, further studies may be able to link these changes to the increased rates of PreE and IUGR at altitude and contribute to the understanding of these two disorders.

The goal of this clinical trial is to learn if a Decision Aid can help patients with Parkinson's disease make a decision about undergoing Deep Brain Stimulation surgery. The main questions it aims to answer are: * Is the Decision Aid acceptable to patients with Parkinson's disease considering Deep Brain Stimulation surgery? * Does the decision aid improve decision quality (informed, value-based decision) and uncertainty about the decision? Researchers will compare immediate use of the decision aid during the evaluation process for deep brain stimulation surgery to delayed introduction of the decision aid. Participants will: * Receive the decision aid at the beginning of the evaluation process or towards the end * Complete surveys at 5 visits (remote or in-person) over approximately 6 months Read Less

The goal of this clinical trial is to determine how changes in exercise and psychosocial stress may influence the risk of menstrual cycle irregularities in female runners and cyclists. The main questions it aims to answer are: * Does the implementation of exercise or psychosocial stress effect circulating reproductive hormones (i.e., estradiol, progesterone, luteinizing hormone) and menstrual cycle length? * Is there an additive effect of combined exercise and psychosocial on circulating reproductive hormones (i.e., estradiol, progesterone, luteinizing hormone) and menstrual cycle length? Participants will be asked to do the following over the \~3 month enrollment period: * attend a laboratory visit at the beginning and end of the study to have their resting metabolic rate, aerobic fitness, and body composition tested * monitor their menstrual cycle length, daily perceived stress levels, physical activity, and diet each month * provide several urine and saliva samples each month * either maintain their usual physical activity and lifestyle habits (control group), increase the duration of their weekly running or cycling mileage by 30% (exercise stress group), complete cognitive function tasks designed to be stressful (psychosocial stress group), or increase the duration of their weekly running or cycling mileage by 30% and complete cognitive function tasks designed to be stressful (exercise + psychosocial stress group) during the final month of enrollment. Researchers will compare control, exercise stress, psychosocial stress, and exercise + psychosocial stress groups to see if there is an effect on circulating reproductive hormones (i.e., estradiol, progesterone, luteinizing hormone) and menstrual cycle length.
