Active clinical trials for "Pneumonia"

Hypoxemia is an abnormally low concentration of oxygen in the blood, and is an important sign of cardio-respiratory compromise in acutely ill patients. Pulse oximetry (PO) is a rapid, portable, non-invasive and accurate method of measuring arterial hemoglobin oxygenation (Sp02), and can therefore be readily implemented to detect hypoxemia in the clinical setting. In this research study, we propose to test the hypothesis that the use of pulse oximetry to detect hypoxemia by first-level health workers' in Karachi, Pakistan is useful and feasible for the identification of the infants most urgently in need of medical care. We will enroll 1,400 infants 0-59 days of age who present to one of two primary health centers in Karachi. Infants will undergo brief clinical assessment by a community health worker (CHW) based on the WHO/UNICEF Integrated Management of Neonatal and Child Illness (IMNCI) algorithm, assessment by two pulse oximetry devices, and examination by a physician. The primary outcomes include prevalence of hypoxemia, feasibility of PO (e.g., time to obtain measurement, number of infants for who repeat measurements are required), and concordance between paired measurements on separate devices.

4 tubes (2 x7-ml dry tubes with yellow gelose, and 2 x 5 ml tubes with blue CTAD) will be taken from the patient within 24 hours following inclusion (D0) in the department in which the patient is hospitalised 4 tubes (2 x7-ml dry tubes with yellow gelose, and 2 x 5 ml tubes with blue CTAD) will be taken from the patient every 7 days following inclusion for 5 weeks (if the patient is still in hospital at the time), in the department where he/she is hospitalised (D7, D14, D21, D28, D35). Samples will no longer be taken once the patient has left the CHU, even if all of the samples have not been taken. For children less than 6 years old, only 2 tubes (1 x 7 ml dry tube with yellow gelose, and 1x5 ml tube with blue CTAD) will be taken following the same timetable. For hospitalised patients, a leeway of 48 hours is authorized for the sampling procedure. Samples will be taken at the same time samples are taken for the usual care of the patient. The tubes will be taken to the Bacteriology Laboratory using the usual collection circuit of the CHU. These tubes will then be redirected to the Infectious Diseases Laboratory to be centrifuged and then stored at -80°C. The strain of Streptococcus pneumoniae isolated in the patient will be preserved at -80°C. If strains other than Streptococcus pneumoniae are isolated, these different strains will all be preserved at -80°C under the same identification number.

This study aims to determine whether interpretations of bronchoscopic results enable physicians to successfully predict the presence of pneumonia in traumatically injured patients.

The identification of all cases (44 patients) was carried out from the database of microbiology, University Hospital Reina Sofía and the University Hospital of Jerez. For the identification of controls, in case of neutropenic patients, all colonized patients that were included during the study period did not receive any decolonitation treatment; in case of non-neutropenic patients it was studied a paired control by the presence of risk factors that indicated the beginning of decolonitation treatment.

Serotype distribution and estimation of antimicrobial resistance in S. pneumoniae isolates and anticipated PCV7 and PCV13 coverage is difficult in Greece, because invasive isolates collected each year are limited and depict a certain proportion of patients who have easy access to tertiary care or have underlying medical reasons which necessitate inpatient care. It is also probable that the real burden of pneumococcal disease is not well estimated especially among adults. New additions in the laboratory setting such as the pneumococcal urine antigen assay (Binax NOW®) and the Urinary Antigen Diagnostic Assay (Luminex) for the detection of 13 serotype specific polysaccharides in human urine developed by Pfizer might be helpful in identifying more pneumococcal infections compared to the previous years. This NIS is based on the unmet scientific need to describe the serotype distribution and the resistance profile of isolates from X-Ray confirmed CAP in the present circumstances.

This is a prospective observational study assessing the clinical outcomes of children 2 to 59 months of age with both pneumonia and other co-morbidities presenting to a tertiary hospital outpatient setting in Malawi, Africa who are most at risk for mortality or have other complications and thus, are typically excluded from childhood pneumonia studies.

An observational two-center case-control study exploring the clinical impact of double-carbapenem use in a population of critically il patients with severe carbapenem-resistant Klebsiella pneumoniae infection

The specific objectives focus on using a train-the-trainer model to educate CHWs in Pakistan on performing and interpreting pediatric lung POCUS. In the first phase, the POCUS experts from Toronto will rigorously train the first generation of local lung POCUS users who are Pakistani health care providers to become local lung POCUS trainers. These first generation trainers will subsequently collaborate with the POCUS experts from Toronto to develop a two-day training program for lung POCUS image interpretation and acquisition that is tailored to novice users (CHWs) in low-resource settings. In the second phase, the first generation local lung POCUS trainers will deliver and evaluate the new training program to the second generation of users - a group of CHWs in Karachi. In the third phase, we will establish the reliability of CHWs to perform lung POCUS on pediatric patients with respiratory symptoms, upon completion of the training program developed by local trainers.

This is an epidemiological study to investigate the etiology of radiographically-confirmed community-acquired pneumonia (CAP) in adults aged ≥18 years. The main objective is to determine the proportion of which cases that is due to Streptococcus pneumoniae and the corresponding incidence and serotype distribution. The study will utilize a serotype-specific urinary antigen detection (UAD) assay.

A prospective observational study. Enrolled participants admitted to ICU due to pneumonia and respiratory failure need mechanical ventilator support. Investigators collected the residual specimens, such as sputum from endotrachea aspiration, bronchoalveolar lavage fluid in those participants as the usual care in the ICU. Those residual samples were sent to extract RNA and sequence by using high-throughput sequencing (next-generation sequencing) method. Investigators will compared the microbiome feature between lower respiratory tract and stool specimens in those participants diagnosed as pneumonia with respiratory failure.
