To create a validated computational tool to predict surgical outcomes for pediatric patients with obstructive sleep apnea (OSA). The first line of treatment for children with OSA is to remove their tonsils and adenoids; however, these surgeries do not always cure the patient. Another treatment, continuous positive airway pressure (CPAP) is only tolerated by 50% of children. Therefore, many children undergo surgical interventions aimed at soft tissue structures surrounding the airway, such as tonsils, tongue, and soft palate, and/or the bony structures of the face. However, the success rates of these surgeries is surprisingly low. Therefore, there a need for a tool to improve the efficacy and predict which surgical option is going to benefit each individual patient most effectively. Computational fluid dynamics (CFD) simulations of respiratory airflow in the upper airways can provide this predictive tool, allowing the effects of various surgical options to be compared virtually and the option most likely to improve the patient's condition to be chosen. Previous CFD simulations have been unable to provide information about OSA as they were based on rigid geometries, or did not include neuromuscular motion, a key component in OSA. This project uses real-time magnetic resonance imaging (MRI) to provide the anatomy and motion of the airway to the CFD simulation, meaning that the exact in vivo motion is modeled for the first time. Furthermore, since the modeling is based on MRI, a modality which does not use ionizing radiation, it is suitable for longitudinal assessment of patients before and after surgical procedures. In vivo validation of these models will be achieved for the first time through comparison of CFD-based airflow velocity fields with those generated by phase-contrast MRI of inhaled hyperpolarized 129Xe gas. This research is based on data obtained from sleep MRIs achieved with the subject under sedation. While sedating the patient post-operatively is slightly more than minimal risk, the potential benefits to each patient outweigh this risk. As 58% of patients have persistent OSA postsurgery and the average trajectory of OSA severity is an increase over time, post-operative imaging and modeling can benefit the patient by identifying the changes to the airway made during surgery and which anatomy should be targeted in future treatments.

In this project, the investigators seek to understand the role of endothelial cells in Cystic Fibrosis (CF) lung disease. This objective will be achieved by conducting a cross sectional clinical study to define the morphology of the pulmonary circulation across a range of lung function coupled with a mechanistic study of the effect of dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR) in endothelial cells on vasculogenesis, epithelial morphogenesis and epithelial CFTR function. Toward that end, the investigators propose the following hypotheses; (a). Loss of pulmonary small blood vessels begins early in the CF lung and worsens with disease progression, (b).VEGFR2-CFTR interactions happen at the plasma membrane of endothelial cells and is likely to be involved in transendothelial ion transport (c) impaired VEGFR2-CFTR interactions on the endothelial cells will have a profound effect on vasculogenesis, epithelial morphogenesis and ion transport. The first hypotheses will be tested through this clinical study. The following 2 hypotheses will be tested through laboratory studies that do not involve human subjects. Read Less

The investigators are wanting to learn more about early development of the lungs and to help them better understand prematurity and the development of a breathing disorder call BPD (Bronchopulmonary Dysplasia) Read Less

Pentoxifylline (PTX) is a medication that has been on the market since 1984 for use in disease in the blood vessels of the legs. There is some preliminary information that it may protect the kidneys from damage due to diabetes and other diseases. "Pentoxifylline in Diabetic Kidney Disease" is a study to bee conducted in 40 VA hospitals across the nation to determine definitively whether or not PTX can prevent worsening of kidney disease and delay death in patients with diabetic kidney disease.

This research study has 2 purposes: 1. To learn about new ways to use Magnetic Resonance Imaging (MRI) to take clearer pictures of the lungs. A type of MRI called Ultra Short Echo Time (UTE) will be used as well as traditional MRI. 2. To collect images and health information about lungs that have different kinds of lung diseases to compare to healthy lungs. This collection will help researchers and clinicians to better understand lung variations in health and disease. This study will involve one MRI session that will take about 10 to 30 minutes and for some participants a breathing test that measures how well the lungs are working. This test is called spirometry.

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD). The overall goal of the study is to continue to discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research. Read Less

Rotator cuff tear is one of the most common reasons to seek musculoskeletal care, and cuff repair is one of the fastest growing ambulatory surgery procedures. However, the etiology of cuff tears, reasons for variability treatment success, and causes of FI are poorly understood. A large-scale genome-wide association studies (GWAS) using imaging-verified rotator cuff tear cases and controls can address limitations in rigor of prior research and assess the genetic basis of FI and functional outcomes of cuff tear treatments. Primary Objective: To conduct a case-control GWAS of imaging-verified symptomatic rotator cuff tear in approximately 3000-6000 individuals and replicate findings in an independent set of 3000-6000 or more imaging-verified individuals to identify common variants in several genetic loci that increase risk for rotator cuff tears. Hypothesis: Common variants in several genetic loci increase risk for rotator cuff tears. Secondary Objectives: 1. To perform an imputed transcriptome-wide association study (TWAS) to identify and prioritize gene targets associated with rotator cuff tear by integrating GWAS summary statistics and gene-expression weights from muscle and adipose tissue available in the GTEx project. Hypothesis: Genetically predicted gene expression of multiple genes in muscle and adipose tissue are associated with rotator cuff tear. 2. To identify if single nucleotide polymorphisms (SNPs) associated with rotator cuff tear and their genetic risk score (GRS) predict improved pain and function as measured by American Shoulder and Elbow Surgeons Standardized Form (ASES) and other outcome measures. Hypothesis: Select SNPs and GRS predict ASES outcome. 3. To identify genetic variants associated with Fatty Infiltration (FI) in patients with cuff tears in a two stage GWAS of imaged rotator cuffs and to prioritize gene targets through an imputed-TWAS in muscle and adipose tissue. Hypothesis: Multiple genetic variants are associated with FI and some exert their influence by altering gene expression in the muscle and adipose tissue. Read Less
