Gastroesophageal reflux disease (GERD) is caused by food or acid coming up from the stomach into the esophagus, repeatedly. The esophagus is the tube that carries food and liquids from the mouth to the stomach. The body uses stomach acid to break down food, but when acid rises up into the esophagus it can hurt or damage it. People with GERD often feel food coming back up into the throat and mouth and have a burning feeling in their stomach, chest, or throat, called heartburn. Other symptoms of GERD include pain in the stomach or throat, difficulty eating, and throwing up. Sometimes GERD damages the lining of the esophagus, creating breaks. This is called erosive esophagitis (EE). Dexlansoprazole is a type of medicine that helps lower the amount of acid made in the stomach. It has been shown to heal EE and maintain (keep) healing of EE in adults and teenagers. This study is being done to find out if dexlansoprazole can also heal EE and maintain the healing of EE in children. Read Less

The goal of the study is to learn about the safety and how effective two different strengths of D-MNA compared to a placebo (a look-alike substance that contains no drug) in the treatment of nodular basal cell skin cancer Read Less

This randomized trial will evaluate the effect of fenofibrate compared with placebo for prevention of diabetic retinopathy (DR) worsening through 6 years of follow-up in eyes with mild to moderately severe non-proliferative DR (NPDR) and no CI-DME at baseline. In addition to evaluating efficacy, this study aims to evaluate the feasibility of a model for ophthalmologists to prescribe or collaborate with a primary care provider such as an internist/endocrinologist to prescribe and monitor the drug safely. If this study demonstrates that fenofibrate is effective for reducing the onset of proliferative diabetic retinopathy (PDR) or and the results are adopted by the community of retina specialists, a new strategy to prevent vision threatening complications of diabetes could be widely adopted. Widespread use of an oral agent effective at reducing worsening of DR would decrease the numbers of patients who undergo more invasive and much more expensive treatment for DR and who are consequently at risk for side effects that adversely affect visual function. This study will also assess the relationship of glycemic variability, as measured by continuous glucose monitoring with DR outcomes. Ancillary studies will characterize functional and structural outcomes in this cohort. Read Less

The purpose of this study is: * To investigate the optimal timing for revaccination after the initial RSVPreF3 OA vaccine dose, * To evaluate the long-term immune persistence and safety up to 5 consecutive RSV seasons (approximately 60 months) of a single dose of RSVPreF3 OA vaccine, * To give the opportunity to participants who received only placebo in the RSVOA=ADJ- 006 study, to receive a dose of the RSVPreF3 OA vaccine and collect additional safety information.

The aim of the study is to compare the safety and efficacy of two doses of Nexium in maintaining healing of erosive esophagitis in patients 1 to 11 years of age. Read Less

This randomized phase III trial studies how well crizotinib works in treating patients with stage IB-IIIA non-small cell lung cancer that has been removed by surgery and has a mutation in a protein called anaplastic lymphoma kinase (ALK). Mutations, or changes, in ALK can make it very active and important for tumor cell growth and progression. Crizotinib may stop the growth of tumor cells by blocking the ALK protein from working. Crizotinib may be an effective treatment for patients with non-small cell lung cancer and an ALK fusion mutation. 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

The goal of this clinical trial is to test the usability, acceptability, and preliminary efficacy of a digital dietary self-monitoring (dDSM) log that uses positive reinforcement strategies (caregiver praise and gamification) to improve child engagement in DSM. The main aims are to: * Examine the usability of a dDSM log that uses positive reinforcement (praise and gamification) among children 8-12 years and their adult caregivers. * Examine the acceptability of a dDSM log that uses positive reinforcement (praise and gamification) among children 8-12 years and their adult caregivers * Conduct a proof-of-concept trial that examines the effects of positive reinforcement on child DSM behaviors. * Explore differences in children's intrinsic motivation. Participating children will be instructed to self-monitor their daily intake of targeted food groups (fruits, vegetables, sweet and salty snack foods, and sugar-sweetened beverages) for 4 weeks using a personal web-based DSM log. Each child-caregiver dyad will be randomly assigned to 1 of 4 conditions: BASIC, PRAISE, GAME, or PRAISE+GAME. For PRAISE and PRAISE+GAME conditions, caregivers will be instructed to provide daily process praise to their child related to DSM behaviors. For GAME and PRAISE+GAME conditions, logs will integrate three game mechanics: points, levels, and a virtual pet. Points will be accumulated for engaging in DSM behaviors, and accrual of points will evolve a virtual pet over time. Read Less

The PHA Registry (PHAR) is a national study about people who have pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). PHAR collects information from people with PAH and CTEPH who are cared for in participating PHA-accredited Pulmonary Hypertension Care Centers throughout the U.S. PHAR will determine how people with PAH and CTEPH are evaluated, tested, and treated, and will observe how well these participants do. The goal is to see if people with PH are treated according to recommended guidelines, and to see if there are certain factors that can lead to better or worse outcomes. PHAR will include information about people with PAH and CTEPH in the U.S. who are seen at participating PHA-accredited PH Care Centers. PHAR contains data about patient care and outcomes. Specifically, data in the PHAR includes information on diagnosis; clinical status; socioeconomic status; diagnosis test results; body size; treatment information; interest in participating in clinical trials; family health and social history; and information about smoking, alcohol, or drug use. Participants are followed over time, and provide updates such as changes in therapy, how often participants need to go to the hospital, and survival. Such information may help healthcare providers provide better care. Read Less
