This study will evaluate which procedure is the best for patients referred for biopsy of a lung nodule (growth in the lung) meeting the size and location requirements of the protocol. Two different procedures are available for lung nodule biopsy: 1. a computed tomography guided biopsy ("CT-guided biopsy") which consists of sampling the nodule from the "outside-in", through the chest wall with CT guidance, and 2. navigation bronchoscopy, which is a procedure using technology designed to guide a catheter through the natural airway route (wind-pipe and bronchi) to access the nodule.
The aim of this study is to reduce pathologic aspiration and pneumonia in the perioperative period by providing an oral care and oral hygiene education to patients preoperatively. Patients enrolled in the study will be given a dysphagia screening questionnaire, an oral care package and oral hygiene education. Patients who screen positive for dysphagia will be referred to Speech Pathology for evaluation. The rate of postoperative pneumonia will be determined for those who participate in the study and will be compared to retrospective patient data from our institution.

Performing EBUS-TBNA after PET/CT scan may help doctors learn more about the accuracy and ways to find early stage lung cancer.
The purpose of this protocol is to obtain biologic materials from the mediastinal lymph nodes from patients with lung disease and mediastinal lymph node involvement in order to: (1) develop a better understanding of the cause and development of lung disorders involving the mediastinal lymph nodes; (2) identify biologic parameters that help diagnose and predict the behavior of human lung diseases; and (3) identify individuals who will be suitable candidates for other protocols such as those involving investigational new drugs.
The overall purpose of this project is to develop and validate a simple, non-invasive method to detect aspiration of gastro-intestinal fluid into the respiratory tract. In the inpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 4 ingestions (at 2h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by 5 healthy control subjects and 5 patients (3-6 with pulmonary fibrosis; and 3-6 either awaiting or recently undergone lung transplantation) with clinical and laboratory evidence of GER (gastroesophageal reflux) with microaspiration. In the outpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 1 ingestions (at 4h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by 10 patients (3-6 with pulmonary fibrosis; and 3-6 either awaiting or recently undergone lung transplantation) with clinical and laboratory evidence of GER (gastroesophageal reflux) with microaspiration.
Cytological diagnostic accuracy between endobronchial ultrasonography endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) samples using suction versus samples when no suction is applied.
The goal of this study is to demonstrate the feasibility of using a novel, validated panel of Non-Small Cell Lung Cancer (NSCLC) histology-predictive genes (the "A/S signature) as a diagnostic tool for use with small-volume Fine Needle Aspirate (FNA) biopsies. Objectives: 1. To establish FNA biopsy requirements for FNA-based subtype classification of NSCLC. 2. To define a "fixed statistical model" of histologic subtype prediction in NSCLC. Study methods: To establish FNA biopsy requirements for gene expression-based subtype classification of NSCLC, patients with presumed newly diagnosed NSCLC, where radiographic studies and clinical description favor a probable diagnosis of NSCLC, will undergo FNA biopsy according to current standard techniques . For this part of the study, approximately 40 biopsies of confirmed NSCLC will be collected for analysis. To define a fixed statistical model of histologic subtype prediction in NSCLC, we will prospectively collect 50 FNAs. These FNAs will represent Adenocarcinoma (AC) and Squamous Cell Carcinoma (SCC) cases at a ratio of approximately 1:1. Additional cases of not otherwise specified (NOS), should they be encountered, may also be collected for later analysis. FNA samples qualified based on cell number or ribonucleic acid (RNA) yield (depending on the findings of our primary objective)will be assayed on the QGS platform.
Surgical patients have an endotracheal tube inserted into their windpipe to help them breathe while under general anesthesia. These tubes have a "cuff" on the outside that is inflated in the trachea to help prevent fluids from leaking into the lungs. These cuffs come in different shapes and sizes. The TaperGuard endotracheal tube has a taper-shaped cuff that has been shown in animals to decrease the leakage of fluid past the cuff better than a traditional tube that has a barrel-shaped cuff. This study is designed to examine whether the use of the TaperGuard tube during surgery on humans decreases the amount of leakage past the cuff to a greater degree than the traditional barrel-shaped cuff. In addition, the study will investigate whether the use of the TaperGuard tube is associated with a decrease in respiratory complications often seen following surgery which may be related to fluid leaking past the cuff and into the lungs. It is thought that the use of the TaperGuard endotracheal tube will result in a decrease in fluid leakage past the cuff and that it will be associated with a decrease in respiratory complications during the 30 days after surgery.
The purpose of the study is to identify the patients at high risk of developing Acute Lung Injury (ALI) at the time of hospital admission, and before intensive care unit admission. Aim 1- To validate the prediction model (Lung Injury Prediction Score) in a population based sample of hospitalized patients. Aim 2- To determine the significance of health-care related ALI risk modifiers in a population based sample. Aim 3- To compare the short and long term outcomes between patients at high risk who do, and do not develop ALI.
This is a prospective randomized clinical trial with the study cohort comprised of all male and female patients over the age of 21 presenting to the study site for evaluation of lung cancer. The study will enroll 300 subjects, with 150 in each arm. Three sites will be in the study, Mayo Rochester, Mayo Jacksonville and Medical University of South Carolina. Mayo Rochester will enroll approximately 125 subjects. This study does not require subjects to undergo any additional procedures than what they would receive per standard medical care. The consenting subjects will receive EUS and /or EBUS- guided FNA or Mediastinoscopy/Thoracoscopy.
The purpose of the study is to externally validate the acute lung injury/acute respiratory distress syndrome (ALI/ARDS) prediction model (Lung Injury Prediction Score - LIPS) in a multicenter sample of patients at risk presented to the acute care hospitals: United States Critical Illness and Injury Trials Group (USCIITG).
Primary objective: * To estimate the degree of agreement in diagnosis of cytologic samples from mediastinal lymph nodes obtained by Endobronchial Ultrasound (EBUS)-guided Fine Needle Capillary Sampling (FNC) versus Fine Needle Aspiration (FNA). Secondary objective: * To compare the quality of cytologic samples from mediastinal lymph nodes obtained by EBUS-guided FNC versus FNA. The quality of the samples will be assessed initially by MDACC on-site cytology technicians, and then corroborated by physicians in the department of cytology. This assessment will be performed utilizing the Mair's score 3. The score consists of a 0-10 scale: 1-2= poor; 3-6=good; 7-10=superior.
The goal of this clinical research study is to learn how accurately an endobronchial ultrasound transbronchial needle aspiration (EBUS -TBNA) may detect mediastinal lymph node metastases in patients with clinical stage I and II non-small cell lung cancer (NSCLC).
Infants less than 2 years old who have been newly diagnosed with problems swallowing will have pulmonary function tests performed to try to detect the presence of chronic lung disease. Six months later after the infants have received appropriate therapy for their swallowing problems, pulmonary function tests will be performed again to see if there has been any change in their chronic lung disease.
The goal of this clinical research study is to compare 2 different methods for checking lymph glands (in the middle of the chest) for cancer cells.

This trial studies how well radial-probe endobronchial ultrasound works in detecting the complete or partial collapse of the lung in patients undergoing peripheral bronchoscopy. Diagnostic procedures, such as radial-probe endobronchial ultrasound and bronchoscopy, use a thin, tube-like instrument inserted through the nose or mouth to view and take pictures of the inside of the trachea, air passages, and lungs.
This pilot study was a randomized, placebo-controlled, clinical trial to test the safety of using the intravenous form of Prostaglandin E1 (PGE1) in an inhaled form for treatment of hypoxemic respiratory failure in term newborns. The study planned to enroll 50 infants diagnosed with hypoxemic respiratory failure at nine NICHD Neonatal Research Network sites, and randomly assign them to receive one dose over a 72-hour period of either high concentration PGE1 (300 ng/kg/min), low concentration PGE1 (150 ng/kg/min), or placebo (normal saline, the diluent for the drug). In addition to determining the safety, optimal dose, and duration of the therapy, this pilot trial planned to evaluate the feasibility of conducting a larger, multi-center randomized, blinded placebo-controlled trial.
This multicenter trial tested whether inhaled nitric oxide would reduce death or the need for oxygen in preterm infants (less than 34 weeks gestational age) with severe lung disease.
