Active clinical trials for "Pneumonia"

The investigation serves the identification of pulmonary hypertension (PH) among patients with hypersensitivity pneumonitis (HP). The exact prevalence of PH in HP is unknown. Data from South America indicate that the prevalence of pre-capillary PH amongst patients with HP is higher than 20%. There are no reliable data from Europe so far. According to the investigators previous analysis, more than 400 HP patients have participated in pulmonary rehabilitation at least once in the past 10 years at Klinikum Bad Gleichenberg (Rehabilitation Center for Agricultural Workers in Austria). This collective of patients is to be invited to participate in the study. A diagnostic algorithm will be applied in the clinical trial, in the case of clinical suspicion the diagnosis of PH will be confirmed by right heart catheterization. Besides the determination of the prevalence of PH in patients with HP the investigators aim to assess the reliability of non-invasive methods (e.g. Echocardiography, ECG...) to predict PH.

Retrospective cohort analysis of children hospitalized for pneumonia comparing disease severity on admission, clinical course, treatment and outcomes and prospective telephone based Follow-Up assessement.

Prospective, multicenter observational study to collect Escherichia coli (E. coli) isolates originating from mechanically ventilated intensive care unit (ICU) patients; in order to characterize phenotype and genotype of E. coli strains retrieved from the lower respiratory tract of ventilated patients.

The investigators will develop a radiomics signature for immune checkpoint-induced pneumonitis in 40 patients with a pulmonary event under anti-PD1 or anti-PD-L1 (cases) and 40 patients without a pulmonary event under anti-PD1 or anti-PD-L1 (controls). On the basis of the case-control study of patients treated with anti-PD1 or anti-PD-L1, they will further optimise the model using reinforcement machine learning. The model will then be validated in 300 prospective patients.

The aim of this prospective cohort single-center observational study is to determine the impact of hyperoxemia on ventilator-associated pneumonia (VAP) occurrence. SpO2 will be continuously recorded in order to determine the percentage of time spent with hyperoxemia. Patients with VAP will be prospectively identified. Patient characteristics and risk factors for VAP will be prospectively collected. Oxidant stress will be prospectively investigated in study patients: glutathion peroxidase (GPX), plasmatic superoxyde dismutase (SOD), total plasmatic antioxidant status (SAT) and urinary 8-isoprostanes will be performed at ICU admission, once a week, and at VAP occurrence. Patients with VAP will be compared with those with no VAP

This is a prospective study of up to 250 participants, from birth to 18 months, who have already had a chest x-ray while a patient at the National Institute of Health (NICH) in Karachi, Pakistan. Participants will include both males and females as well as all races and ethnicities. Participants will have thermal pictures of their chest taken by trained study staff using a Smartphone and a FLIR ONE attachment. Thermal images will be read by trained radiologists to determine if bacterial pneumonia is present. Results of the thermal image will then be compared to the results of the chest x-ray. If additional images of the chest or other areas of suspected related infection are available, additional thermal images will be taken of the same location within 24 hours of the other image.

Pyogenic liver abscess (PLA) is a complication of infectious disease, and the most common pathogen of PLA is Klebsiella pneumoniae, while PLA caused by Carbapenem-resistant Klebsiella pneumoniae (CRKP) has become a threat to public health. For achieving a better therapeutic outcome of CRKP related PLA, it is very important to figure out the basic characteristics and risk factors of CRKP-PLA. A retrospective cohort study was performed in which 15 PLA patients carriage of K pneumoniae were screened at the Xiangya hospital of central south university (changsha, China). The colonization and clinical infection isolates were analyzed by antimicrobial susceptibility testing to identify CRKP. All admission patients diagnosed with PLA who developed CRKP were included, 5 adults PLA patients with CRKP infected and 10 adults PLA patients with Carbapenem sensitive Klebsiella pneumoniae (CSKP) infected were conducted. Univariate and multivariate logistic regression was carried out using a stepwise selection method to compare prognostic factors between CRKP and CSKP groups.

The study compares a device that is used for the detection of bacteria and MDR pathogens from skin, soft tissue and nose with the gold-standard (microbiological lab). It is a novel use for this device because it has been used in samples from the lower-respiratory tract.

The aim of the project is to identify the prevalence and characteristics of long-term cardiovascular changes in Covid-19 infection.

This study evaluates the respective values and combined CPIS (Clinical Pulmonary Infection Score), bronchoalveolar lavage (BAL), tracheal aspiration and pulmonary ultrasonography (LUS - Lung Ultrasound) for early diagnosis of ventilator- associated pneumonia (VAP).
