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

The proposal is aimed at identifying genetic factors that determine the incidence and severity of, and the outcome from life-threatening infections (severe sepsis/septic shock) in patients admitted to High Dependency Units (HDUs) or Intensive Care Units (ICUs) with pneumonia which developed outside the hospital (community acquired pneumonia - CAP) or contamination of the abdominal cavity with faeces due to a leak in the bowel (faecal peritonitis). This will require the acquisition of a large, high quality resource of genetic material (DNA), plasma, urine, white blood cells and clinical information from well characterized groups of similar patients with, or at risk for, severe sepsis/septic shock. The principal objective is to perform studies which are sufficiently large to establish beyond doubt the influence of a series of selected "candidate" genes on the development, progress and outcome of sepsis.

OBJECTIVES: I. Compare the resting energy expenditure using respiratory calorimetry in infants and children with moderate to severe cystic fibrosis versus age matched healthy controls. II. Determine the total energy expenditure and energy spent on physical activity using the doubly labeled water method in these patient populations.

OBJECTIVES: I. Determine the total energy expenditure in term and preterm infants in both well and ill states using the doubly labeled water method.

SAM-COVID is a retrospective cohort study that aims to determine the impact of immunosuppressive drugs and immunoglubulins in the outcome of patients with COVID-19.

This study is a single center, minimal risk, physician initiated retrospective chart review. An analysis of treatment timelines for patients diagnosed with lung cancer within the St. Elizabeth system from January 2013 until study completion. The study investigator and designee(s) will review patient electronic medical records, extracting data related to the symptom presentation, diagnosis, and treatment of new diagnoses of lung cancer. Collected data will focus on dates of encounters, diagnostic imaging/procedures, and treatments, with data analysis evaluating time between care encounters and potential delays in care. The data will be further stratified based on system-wide changes implemented to improve efficiency, patient outcomes, and patient experience.

This prospective multicenter registry study aims to determine whether device-detected sleep-disordered breathing events are associated increased risk of cardiac arrhythmias or other cardiovascular outcomes.

The purpose of this study is to Understand the prevalence of non-tuberculous mycobacterial(NTM) infections in the middle-aged and old women patients with bronchiectasis in Mainland China, and explore the characteristics of patients with bronchiectasis comorbid NTM.

Pneumonia continues to be a leading cause of death in children under five years of age worldwide. Many studies have evaluated clinical signs and symptoms that may predict pneumonia. A recent meta-analysis found that no singular physical exam finding predicted pneumonia. The World Health Organization (WHO) Criteria diagnose pneumonia based on fast breathing; however, tachypnea has not been shown to strongly predict pneumonia. This study will evaluate accuracy of clinical history, physical exam and WHO criteria, laboratory findings, and lung ultrasound compared with chest radiograph for the diagnosis of pneumonia in children under five years of age in a resource limited setting. Determining diagnostic accuracy of these findings may help derive a clinical decision rule that may more accurately predict which children have pneumonia than current WHO guidelines.

Chronic obstructive pulmonary disease is a serious disease . Exacerbations of Chronic obstructive pulmonary disease is an acute worsening condition of Chronic obstructive pulmonary disease, which always accompanied by clinical symptoms such as, shortness of breath and increased production of sputum. Respiratory infection (bacteria or viruses or mixed) is thought to be the main cause in most exacerbations.

The purpose of this study is to establish the large COPD cohort and biological database in China, aiming for precision medicine to optimize diagnosis and treatment choices.
