Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

The purpose of this feasibility study is to test a device which analyzes breath and may allow doctors and health professionals to immediately determine if an ill patient has a specific type of bacterial infection. This will allow a health professional to provide immediate targeted antibiotics to properly start treatment without delay.

The objective of this proposal is to conduct a randomized controlled study to examine the association between the increase in extravascular lung water as determined by lung ultrasound and the development of radiologic pulmonary edema as diagnosed by chest roentgenogram in patients undergoing major elective open intra-peritoneal surgeries under general endotracheal anesthesia.

Development of a new MS-based biomarker for the early and sensitive diagnosis of Hyaline fibromatosis syndrome from the blood

This study aims to answer the question of what is the burden of lower respiratory disease (pneumonia) among children ages 1 month to 5 years of age in rural Cambodia. The primary objective will be to quantify the prevalence of severe pneumonia at Chenla Children's Healthcare, a hospital in the rural town of Kratie, Cambodia. This will involve a chart review of the medical records available at Chenla Children's Healthcare.

This study shall determine whether XAPPORT - a mobile device app based on different guidelines, the summary of product characteristics of rivaroxaban, and clinical facts and practice - provides adequate guidance to physicians attending patients undergoing elective surgery, who have to interrupt treatment with rivaroxaban for surgery, in deciding how to approach the pre- and postoperative management of anticoagulation.

Bedside ultrasonography for detection of pneumothorax after transbronchial lung biopsies in lung transplant patients

This is a single center study of 60 subjects including those with asthma and mucus plugging, those with asthma and without mucus plugging, and healthy controls. Screening data will be reviewed to determine participant eligibility. Participants who meet all inclusion criteria will participate in image-guided bronchoscopy ("virtual navigation bronchoscopy" [VNB]) to sample airway biospecimens in mucus plugged and control airways.

As of February 17th, 2020, China has 70635 confirmed cases of coronavirus disease 2019 (COVID-19), including 1772 deaths. Human-to-human spread of virus via respiratory droplets is currently considered to be the main route of transmission. The number of patients increased rapidly but the impact factors of clinical outcomes among hospitalized patients are still unclear.

Protocol Summary Study design: Prospective cohort study of pregnant COVID-19 positive patients at delivery. Study Objective: To collect umbilical cord blood and placenta samples at the time of delivery in COVID-19 positive women and evaluate for presence of COVID-19 virus and maternal antibody response. Inclusion/Exclusion Criteria: Women admitted for delivery who are known or suspected COVID-19 positive who have had standard nasal swab testing for COVID-19. Study Procedures: Informed consent for patients will be obtained. Maternal blood will be collected for viral and antibody tests for COVID-19. Following delivery of the neonate, cord blood and placenta samples will be collected and sent for viral PCR and maternal antibody analysis. Neonatal testing will be done as per existing clinical protocol for infants born to PUI/COVID-19 positive women. Statistical Analysis: Statistical analysis for this study will include descriptive analysis and quantitative statistics of findings.

Dr. Russell Traister, et al, describes a symptom scoring system based on retrospective chart review to help identify subjects with VCD. Dr. Traister assigned the following symptom scores: dysphonia (2), throat tightness (4), sensitivity to odors (3) and absence of wheezing (2). Patients scoring 4 or more points have a positive predictive value of 96% and a negative predictive value of 77% for VCD. This prospective study will look at a population of patients presenting to a large tertiary care referral center for symptoms of cough. Patients seen at the "Cough Clinic" are evaluated by a Pulmonologist and an Otolaryngologist. Each patient undergoes pulmonary function testing and VLS testing as part of the diagnostic workup. For this study the history would be expanded to include the 4 specific symptoms: dysphonia, throat tightness, sensitivity to odors and absence of wheezing. The symptoms will be scored and compared against the results of diagnostic testing to determine if these symptoms help predict those with vocal cord dysfunction (VCD).
