Active clinical trials for "Pneumonia"

COVID-19, caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), is a multisystem disease which primarily involves the respiratory tract. The first case of COVID-19 was identified in late 2019 in the province of Wuhan, China which was followed by the rapid spread of the disease globally, becoming a present-day pandemic. Objectives: The aim of this study was to describe the clinical characteristics, comorbidities and outcome of the critically sick patients with COVID-19 pneumonia admitted in ICU of a tertiary care hospital in Lahore.

Ventilator-associated pneumonia (VAP) is the most frequent infection occurring in patients who are admitted to the ICU. The accumulation of respiratory secretions in the subglottic space is a well-proven cause of VAP. Investigators invented a manual method with high-flow air produced by resuscitator to impinge secretion from the subglottic space to oral cavity. Investigators want to compare it with conventional method which uses a special intubation tube with an independent dorsal lumen to suction subglottic secretion.

The investigators propose to test the feasibility and acceptability of community health workers (ASHAs and ANMs) being able to treat sick children in the community. There is a national policy for treatment for children aged 2-59 months with illnesses such as pneumonia, diarrhea and fever by community health workers (CHWs), this policy has not been implemented as yet in Haryana. This research will identify barriers and opportunities for use of CHWs as treatment sources.

Background: Respiratory diseases affect more than 1 billion people worldwide. They are a growing public health concern. The lungs are constantly exposed to environmental factors such as dust, fumes, microbes, and pollutants. But much is still not known about how these pollutants lead to respiratory illnesses. Researchers want to collect samples from lungs and blood to see how genetics and environmental pollutants affect cellular responses or functioning. Objectives: To study how cytochrome P450 epoxygenase pathway enzymes affect macrophage function in the lungs and inflammatory responses. Eligibility: Adults ages 18 65 who can have a bronchoscopy. Design: All study visits will take place at the NIEHS Clinical Research Unit in Research Triangle Park, NC. At study visit 1, participants will be screened with medical history and physical exam. They will have blood and urine tests. They will take tests that measure their lung function. They will answer questionnaires. Before the visit, they will be given a list of medicines they cannot take. They also must not have caffeine on the day of their visit. The visit will last about 3 hours. At study visit 2, participants will give blood samples. They will undergo bronchoscopy. For this, they will get an intravenous line in a vein to get sedatives. Their airways will be numbed. Cells will be collected from their lungs. They will fast for 8 hours before the visit. They must have someone else drive them home from the visit. The visit will last about 3-4 hours. Participants will get a follow-up phone call about 1 day after study visit 2.

Perioperative changes in regional ventilation by pulmonary electrical impedance tomography and spirometry will be investigated in patients at risk for postoperative pulmonary complications. Those patients undergo abdominal and limb operations. In a pilot study arm electrical impedance tomography is tested in patients receiving osteosynthesis of serial rib fractures.

The objective of this Clinical Trial is to define the methods to be used to document that illumigene® Mycoplasma Direct meets its intended use claims, using the illumipro instrument, with throat swab samples collected from symptomatic patients.

To investigate exposure to nonsteroidal antiinflammatory drugs (NSAIDs) during outpatient management at the early stage of community-acquired pneumonia (CAP) requiring hospital consultation. Non-interventional observational study.

The purpose of this study is to learn more about new noninvasive ways of detecting lung disease in US Military personnel and people who worked as contractors during military operations in Iraq and Afghanistan. This study is looking at conducting a type of breathing test called the lung clearance index (LCI) test which is being investigated as a potential noninvasive way to detect the type of lung disease that may be seen in symptomatic deployers retuning from Iraq and Afghanistan.

The ULTRACHEST study will be a prospective clinical diagnostic performance study with primary objective to establish device diagnostic clinical performance of Ultra Low Dose CT (ULD-CT) in order to prove it is more accurate in detecting pneumonia when comparing to standard conventional chest radiography.

The purpose of this study is to evaluate the added diagnostic value of a quantitative polymerase chain reaction targeting the lytA gene in detecting pneumococci in patients with community-acquired pneumonia.
