Randomized with (1:1) prospective, double-blind, controlled trial. Subjects will be randomized to receive S-PRG and the control group receives ICON.
The present study will be performed to Evaluate the treatment outcome of anterior open bite by temporary anchorage device on buccal and palatal mini screws
This project will evaluate new approaches to quantify and reduce chemical exposures from common building materials, with an emphasis on plastic additives, pesticides, flame retardants and lead in addition to other environmental contaminants. The objective of this project is to develop methods to quantify and reduce chemical exposures from the home environment using approaches that are adaptable and customizable to individuals and households. To achieve this goal investigators will: 1) Identify the types of building materials and housing characteristics associated with higher levels of exposure to different classes of contaminants; 2) Assess the effectiveness of a simple robotic vacuuming intervention for reducing exposure to a range of indoor contaminants; and 3) Evaluate a new wearable silicone wristband for monitoring exposure to lead and other metals.
The purpose of this study is to evaluate the long-term safety, tolerability, and efficacy of vanzacaftor/tezacaftor/deutivacaftor (VNZ/TEZ/D-IVA) in participants with cystic fibrosis (CF).
The purpose of this multi-site research is to validate a rapid magnetic resonance based confounder-corrected R-2 mapping method as a quantitative imaging biomarker of liver iron concentrations.
The purpose of this study is to evaluate the effect of a parenteral emulsion containing n-3 long-chain polyunsaturated fatty acids (LC-PUFA) in fish oil on clinical outcomes, markers of inflammation and oxidative stress, and pain in neonates with persistent pulmonary hypertension of the newborn (PPHN) compared with those who receive an emulsion containing soy oil and medium-chain triglycerides (MCT) without n-3 LC-PUFA.
Acute pulmonary embolism (PE) in critically ill patients is common and often life threatening. The diagnosis of acute PE is often entertained in intensive care unit patients who develop unexplained hypotension or hypoxemia. Obtaining diagnostic confirmation of acute PE with a contrast-enhanced computed tomography of the chest (CT angiogram) may be difficult as patients are often too unstable for transport to the CT scanner or have renal insufficiency limiting the ability to receive intravenous contrast agents. Making or excluding the diagnosis of acute PE in these patients is critically important, as hemodynamic instability or right heart dysfunction, if due to PE, puts patients in the massive or submassive category and increased mortality risk. More aggressive therapies such as thrombolysis, extracorporeal membrane oxygenation or surgical embolectomy are often entertained. The investigators have previously described a case where endobronchial ultrasound (EBUS) was employed in the diagnostic algorithm of suspected acute PE and significantly affected treatment recommendations. The investigators believe that, in these patients, use of EBUS to assess for thrombotic occlusion of the central pulmonary vasculature can fill a critical gap in the decision tree for management of these patients. EBUS has become part of the diagnostic approach in a number of clinical situations, including the workup and staging of suspected malignancy, unexplained lymphadenopathy, and diagnosis of mediastinal and parabronchial masses. There is strong evidence that EBUS is equivalent to mediastinoscopy in the mediastinal staging of lung cancer. The number of physicians skilled and experienced in performance of EBUS has increased dramatically, and training in the procedure is frequently obtained in a pulmonary fellowship. To our knowledge, there have been no prospective studies that investigate the use of EBUS as a tool for the diagnosis of acute central pulmonary embolism in critically ill patients where obtaining diagnostic confirmation of this diagnosis with a contrast-enhanced computed tomography of the chest is not safe or feasible.
Transition from paediatric to adult health care is crucial for preventing deterioration of chronic diseases. At present, transitional care (TC) is not established for patients with the Hirschsprung disease (H) and Anorectal Malformations (ARM). To set up a program for TC and to treat persisting symptoms in adults, data on outcome in adult patients are needed. At present such data are very limited. Therefore, we want to investigate clinical and PROM in H and ARM adolescents and adults. A cross sectional study in all H and ARM patients operated in Norway from 1970-2000 and in all adolescents operated at Oslo University Hospital from 2002-2006 will examine somatic, psychosocial and mental health, and quality of life (QoL). In children operated for H and ARM a large body of evidence shows that bowel problems, reduced QoL and impaired psychosocial and mental health are common. There are papers on sexual and urological impairment in these patients, but large studies on the topic is missing. It is a general assumption among paediatric surgeons that both somatic and mental health problems related to H and ARM improve during adolescence and adult life. Therefore, no standardized guidelines for TC in these patients have been established. Interestingly, very few studies have actually examined H and ARM patients beyond adolescence. Reports from patient organizations showing significant long-term sequels and inadequate understanding of the unique problems of H and ARM patients among health professionals treating adults. Hypothesis:H and ARM adults and adolescents have bowel, urinary and sexual difficulties and reduced QoL, psychosocial and mental health. H and ARM adults receive insufficient treatment of their chronic congenital disease. H and ARM patients with syndromes have particularly bad functional outcome. Anal dilatations and repeated rectal enemas have a negative impact on adolescent psychosocial and mental health. Main aim: Acquire knowledge about long-term bowel, urinary and sexual function, QoL and psychosocial and mental health in adult and adolescent H and ARM patients. Results: from this large study of H and ARM patients will have significant influence on treatment and follow-up, both nationally and internationally. Since very few countries except the Nordic countries have the possibility to follow patients with congenital malformations into adulthood, it is important that studies like this are done.
The purpose the research is to better understand how the human brain accomplishes the basic cognitive tasks of learning new information, recalling stored information, and making decisions or choices about presented information. These investigations are critical to better understand human cognition and to design treatments for disorders of learning and memory.
Background: Alcohol use disorder (AUD) is a major public health problem. In the U.S., 16 to 18 million adults have an AUD. Researchers want to test an assessment tool called the ANA. It uses self-report and behavioral measures to assess 3 neuroscience domains of addiction. They hope to better understand, manage, prevent, and treat AUD. Objective: To learn how people s brains function related to their drinking. Eligibility: People ages 18 years and older who have enrolled in NIAAA natural history study 14-AA-0181. Design: Participants will complete surveys and tasks on a computer. The surveys and tasks assess a range of aspects of thinking and making decisions. The surveys and tasks also assess behaviors and feelings about alcohol and other rewards, and negative emotions. Participants will spend 90 minutes on the computer. Then they will take a break. In total, they will spend 4 blocks of time on the computer. Each block will last 90 minutes. They will take a break in between each block of time. They can take more breaks if needed. Outpatient participants and healthy volunteers will complete this study in 1 visit. It will last about 6 hours. A second visit may be scheduled if needed. Outpatient participants will take a breath alcohol test. If their test is positive, their visit may be rescheduled or they may be withdrawn from the study. Inpatient participants will complete this study over several days. Data collected from participants in this study may be combined and analyzed with their data from NIAAA study 14-AA-0181 and/or NIAAA imaging study 14-AA-0080.
