Active clinical trials for "Pneumonia"

The purpose of this observational study is to collect prospective data on the occurrence of bacterial and viral pneumonia in the ICU setting. Current classification systems for pneumonia promote over treatment with antibiotics as they do not specifically recognize the presence of culture-negative and viral pneumonia. The investigators will collect data to determine if a novel pneumonia classification system can be developed that more accurately links the etiology of pneumonia (antibiotic-susceptible bacterial pneumonia, antibiotic-resistant bacterial pneumonia, culture-negative pneumonia, viral pneumonia) to clinical outcomes. Additionally, the investigators will collect data on the practice of antimicrobial stewardship in the ICU setting to determine if further improvements in antibiotic practices can be accomplished in the future.

This study investigates relationship between community acquired pneumonia and oropharyngeal dysphagia in patients admitted to a department of respiratory medicine in Northern Denmark. The endpoints will be re-hospitalisation and mortality.

Pseudomonas aeruginosa is the main pathogen of nosocomial respiratory infections. Its increasing resistance to antibiotics requires the development of new strategies for prevention and control, demanding a better understanding of the modes of transmission and evolutionary dynamics of this bacteria. In patients under invasive mechanical ventilation, the main mode of contamination by Pseudomonas remains debated, with 3 modes of contamination (endogenous, crossed transmission between patients, or environmental origin) of varying importance, mainly depending on the endemic situation of the place of study. The emergence of new genotyping technologies (DiversiLab) can now facilitate studies of molecular epidemiology. Thanks to the multidisciplinary collaboration and innovative techniques, the investigators wish to study the impact of the mode of contamination on the outcome of ICU patients, intubated and ventilated for more than 72 hours.

The purpose of this non-interventional, retrospective study of existing data is to evaluate clinical outcomes related to Methicillin-resistant Staphylococcus aureus hospital based pneumonia by treatment and among subpopulations.

Hospitalized patients with ventilator are randomized to receive fermented dairy product containing L. casei shirota or nothing. The main outcome is development of ventilator-associated pneumonia (VAP)

Background The prediction of multi-drug resistant (MDR) pathogens is a key issue in the management of health-care associated pneumonia (HCAP). Multiple risk factors have been proposed, some of which overlap with items of the pneumonia severity index (PSI). The aim of this study was to investigate the relationship between PSI and presence of MDR pathogens. Methods Patients who were admitted to a tertiary-care hospital from January 2005 to December 2010 were screened by a discharge diagnosis of pneumonia. Patients were enrolled if they fulfilled the definition of HCAP by 2005 ATS/IDSA guideline.

The purpose of this study is to determine if the daily use of a certain amount and type of milk component for 2 months provides a significant stimulation to the immune system and specifically increases the chances of being protected against pneumonia after the vaccination.

The macrolide group of antibiotics can cause QT prolongation, and endanger the patient with life threatening arrythmias. QT prolongation caused by Azythromycin, a relatively new macrolide, is extremely rare, and was not reported in clinical trials. Our hypothesis is that patients hospitalized with severe community acquired pneumonia, usually with multiple comorbid conditions will have a higher rate of QT prolongation, compared to the clinical trials published

The purpose of this study is to find out if there is a link between cigarette smoking, inflammation and the spread of breast cancer to the lung. We think that women who are current or former smokers may be at increased risk for breast cancer spreading to the lung compared to women who have never smoked. Smoking causes inflammation in the lung in some women. Researchers at Memorial Sloan-Kettering (MSKCC) think that smoking-related lung inflammation may increase the chance of breast cancer spreading to the lung. In order to find out whether inflammation plays a role in breast cancer spreading to the lung, we will measure a urinary marker of lung inflammation. This will allow us to determine if this marker is more commonly elevated in women with breast cancer that has spread to the lung compared to those without breast cancer in the lung. We will also collect DNA from blood to have the opportunity to determine if there are differences in DNA in women with or without breast cancer that has spread to the other sites including the lung. We will also collect blood to determine if we can identify risk factors for the spread of breast cancer to the lungs.

The specific aim is to evaluate the impact of PCV13 as administered in the pediatric primary care clinic at Boston medical center on the serotype specific carriage of Streptococcus pneumoniae in children < 5. Specifically the investigators will measure the decline in vaccine serotypes, the proportion of children receiving vaccine required to achieve 50% reduction in serotype specific carriage and the correlation between immunogenicity of the specific serotypes and decline in carriage. The study has been extended to complete 5 years of surveillance to determine the new SP serotype distribution at the time presumably a new equilibrium has been achieved.
