Prospective Clinical Evaluation of the Taperguard Endotracheal Tube
Postoperative PneumoniaThis protocol is designed to determine if a transition from barrel-shaped cuff designs to the Taperguard endotracheal tube (ETT) reduces the incidence of postoperative pneumonia in a prospective evaluation of a large general, vascular, orthopedic, urologic and neurologic surgical population. The protocol was originally developed as a quality assurance project to evaluate a practice change that took place December 1, 2012. Data regarding postoperative pneumonia and related factors will be reviewed for the 18 months prior to the practice change and compared to data from the 14.5 months following the change. Since the results may be of interest to a wider audience, we are converting the project to a research study that may be published in the future. The study will include data from all adult patients who had surgery at OHSU between June 1, 2011 and February 15, 2014. We anticipate that we will enroll approximately 40,000 subjects (at least 22,000 in the pre-intervention group and at least 16,000 in the post-intervention group). Data will be gathered from the OHSU electronic medical record system (Centricity and Epic). 6. A multiple logistic regression analysis will be employed to determine the rates of pneumonia between the use of a standard barrel-cuff designed ETT and the Taperguard ETT for the defined group of surgical patients. The regression analysis would be adjusted for confounding variables including ASA status, age, use of paralytic, RSI with cricoid pressure, weight, pre-existing lung disease.

Diagnostic Value of Lung Ultrasound for Ventilator-Associated Pneumonia
Ventilator-Associated PneumoniaVentilator-associated pneumonia (VAP) is the most common nosocomial infection acquired by mechanically-ventilated patients in the intensive care unit (ICU). It has significant clinical and economic consequences, as it is associated with considerable morbidity, increased mortality, and excess health care costs. Appropriate antibiotic therapy for patients with VAP significantly improves outcomes, making rapid identification of patients with VAP an important clinical goal. This application is for support of a prospective, multi-centered study to evaluate the diagnostic value of lung ultrasound for VAP. The primary hypothesis is that the association of the Clinical Pulmonary Infection Score (CPIS) to specific lung ultrasound signs could allow for early and reliable diagnosis of bacterial VAP. Objective 1: To evaluate the sensitivity, specificity, and diagnostic accuracy of lung ultrasound alone and in association with the CPIS. Objective 2: To determine the frequency of specific lung ultrasound signs (subpleural consolidation, irregular B-lines) in VAP. Objective 3: To promote development of a diagnostic pathway for VAP incorporating CPIS, lung ultrasound, and unprotected tracheal aspirate (UTA).

Thermal Imaging of the Lung on a Smartphone to Differentiate Bacterial From Non Bacterial Causes...
PneumoniaBacterial2 moreThis is a study of up to 275 participants from birth to 12 months who are having a chest x-ray while a patient at the Queen Elizabeth Central Hospital in Blantyre, Malawi. 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 study staff to determine if bacterial pneumonia is present. Results of the thermal images will then be compared to the results of the chest X-ray. If additional images of the chest are available, additional thermal images will be taken of the same location within 24 hours of the other image.

Pulmonary and Systemic Effects of Exposure to Wood Smoke
Pulmonary InflammationCytotoxicityThis is study is to assess pulmonary and systemic effects of exposure to wood smoke. Healthy volunteers will be expose under two different occasion to wood smoke and filtered air under two separated occasions with an interval of 3 weeks in-between. The aim of this study was to determine whether exposure to wood smoke from incomplete combustion would elicit airway inflammation in humans.

Burden of Hospitalized Pneumonia in Korea COPD Population
COPDPneumonia1 moreChronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. By 2030, COPD is expected to be the fourth main cause of death. Community-acquired pneumonia (CAP) represents not only a frequent complication but also a deadly cause in COPD patients. Inhaled corticosteroids, which are frequently used among COPD patients increase the risk for pneumonia. The effect of pneumococcal conjugate vaccine 13 (PCV13) on the prevention of pneumococcal pneumonia among COPD patients in Korean population has not been studied yet. Several factors such as multi-lobar pneumonia, Pseudomonas aeruginosa pneumonia, and high pneumonia severity are related to poor outcome of patients with COPD and pneumonia. Prior pneumococcal vaccine has a beneficial effect on outcomes of pneumonia with COPD patients. However, the effects of pneumococcal vaccine on the clinical outcome of COPD patients were evaluated mainly on 23-valent pneumococcal polysaccharide vaccine (PPV23). The beneficial effects of PPV23 rapidly fade out after inoculation, which is more prominent in old age group. In this sense, PPV23 vaccine is not sufficient in preventing pneumococcal diseases in COPD patients because COPD is the disease of old ages and mortality rate increases exponentially with advancing age. Pneumococcal conjugate vaccine 13 (PCV13) can overcome the waning phenomenon by the production of memory B cells. Although PCV13 is expected to be the best option for the prevention of pneumococcal pneumonia in COPD patients, there are few available studies supporting it. In this study, we will conduct prospective, multi-center trial with the collaboration of Korean pulmonologists in five university-affiliated hospitals. In this study, we will evaluate influenza and pneumococcal vaccination status, the pathogen distribution, pneumonia severity, and clinical outcomes of hospitalized pneumonia patients with COPD. If successfully accomplished, this study will enhance the awareness of the preventive use of PCV13 in COPD patients among Korean pulmonologists and, most importantly, it will lead to protection of more COPD patients from pneumococcal pneumonia, one of the most frequent and deadly complication.

Extracellular Water in Covid 19 Pneumonia
Extracellular Fluid AlterationCorona Virus InfectionAccording to various studies Covid 19 pneumonia has a very similar clinical course to Acute Respiratory Distress Syndrome (ARDS) which has clarified by Berlin definition. Based on this similarity, extracellular fluid of lungs and diffuse alveolar damage should be observed in covid 19 pneumonia as well. Extracellular water (ECW) can be determine by using whole body bioimpedence system (NİCaS). The aim of this study is to investigate the effect of ECW on the clinical apperence of covid 19 pneumonia clinical course.

Paediatric Post Pneumococcal Conjugate Vaccine Nasopharyngeal Carriage Study
S. PneumoniaePneumococcal Conjugate VaccineThe investigators intend to investigate the carriage of pneumococci and other respiratory microbes since the introduction of pneumococcal conjugate vaccines (Prevenar 7 and Prevenar 13). The principal aim is to gain a collection of samples that can be used to help investigate any changes that might occur in the epidemiology of microbes that are carried in the upper respiratory tract and which may cause respiratory disease, sepsis or meningitis after the introduction of Prevenar. Nasopharyngeal and nasal swabs will be taken from up to 2,000 children aged 4 years and under in each year of the study. Swabs will be processed using traditional microbiology and molecular diagnostic techniques and isolated microbes such as S. pneumoniae further characterised using molecular methods. The investigators will also ask parents to complete a short questionnaire requesting: basic demographic data; vaccine history; recent illness; overseas travel and antibiotic usage. The study will contribute to the success of the introduction of pneumococcal conjugate vaccines and will play a central role in maintaining confidence. The study will also help provide information for future vaccine policy as further vaccines are developed against microbes which cause respiratory disease, sepsis and meningitis.
