The Efficacy of Babaodan Capsules in Preventing Radiation Pneumonia
Radiation PneumonitisRadiation pneumonitis (RP) is a common complication of radiotherapy for thoracic tumors, and the incidence rate of grade 2 or above RP is 20% -40%; The use of antibiotics after secondary bacterial infection due to radiation pneumonia or the use of systemic glucocorticoids for radiation pneumonia itself have significant adverse effects on the survival of NSCLC patients. At present, FDA has not approved drugs to prevent the occurrence of radiation pneumonia. traditional Chinese patent Babaodan (BBD) capsule has the effect of controlling macrophages to produce proinflammatory cytokines, such as significantly inhibiting the release of IL-6. Through prospective research, this study evaluates the incidence of symptomatic pneumonia (G ≥ 2) in the treatment of locally advanced non-small cell lung cancer with BBD combined with concurrent radiotherapy and chemotherapy.
Validation of Aspiration Markers in Intubated Patients
PneumoniaAspirationThe goal of this interventional study is to test Quinine as marker of aspiration (endotracheal tube [ETT] cuff leakage) in mechanically ventilated, critically ill patients.
Evaluation of Postmortem Pulmonary Interstitial Fibrosis Severity and EGFR Positivity in Covid-19...
PneumoniaViral2 moreThe aim of this study is to examine the relationship between the severity of fibrosis in the lung tissue and EGFR positivity in patients who died due to covid-19 pneumonia, with the demographic characteristics, comorbidities, biochemistry values, treatments they received, and radiological appearances. Transthoracic tru-cut biopsy will be performed on patients who have died in the intensive care unit with the diagnosis of Covid 19 pneumonia. EGFR positivity will be evaluated in the material taken. The relationship between the severity of fibrosis and the demographic data of the patients, the drugs used and their radiological appearances will be analyzed statistically.
Ceragenin Coated Endotracheal Tubes for the Prevention of Ventilator Associated Pneumonia
Ventilator Associated PneumoniaCritically ill patients are at high risk of acquiring pneumonia during the time that they are mechanically ventilated. This is known as ventilator-associated pneumonia (VAP). VAP results in increased duration of mechanical ventilation, increased ICU and hospital stay, increased risk of death and increased health care costs. VAP occurs in 20% of patients and it is estimated that each case of VAP costs the health care system $10 to 15,000 Canadian. Because of its impact on patient outcomes and the health care system, VAP is regarded as an important patient safety issue and there is an urgent need for better prevention strategies. Invasive mechanical ventilation requires the passage of an endotracheal tube (ETT) through the pharynx which is frequently colonized with bacterial pathogens and a bio-film rapidly forms on the ETT. VAP results either from aspiration of contaminated oropharyngeal secretions or from aspiration of bacteria from the bio-film. In this project, the efficacy of a novel ETT coated with an antibiotic compound that has been shown to reduce the formation of bio-film and pathogen colonization will be tested. Preliminary evidence as to whether utilization of this novel ETT reduces the occurrence of VAP and improves patient outcomes will be obtained through the conduct of a pragmatic, prospective, longitudinal, interrupted time, cross-over implementation study.
Mouth Odor on Preventing Pneumonia by Oral Frailty
BreathingMouth2 moreThis research plan aims to first collect data on the oral function and oral hygiene status of the elderly population in the community and to understand the normal model of oral frailty among the older adults in the community. Subsequently, a comparison will be made between the oral status of hospitalized patients and the community-dwelling elderly population. The goal is to verify whether oral odor can be used as an objective biological indicator following intervention.
Ventilator Aspiration With PneuX (PneuX vs Standard Care Feasibility RCT)
Ventilator Associated PneumoniaAspiration2 moreThis is a single centre, open-label, feasibility randomised controlled trial. The study aims to assess the feasibility of conducting an RCT to compare the PneuX ETT with standard care in hospitalised patients requiring mechanical ventilation. The patient population for this study are those who are experiencing critical illness requiring intubation and ventilatory support. Patients will be randomised in equal proportions into one of 2 arms: to be intubated using a Venner PneuX Endotracheal Tube (ETT) or using the standard tube. For this feasibility study, a total of 50 patients will be randomised into two groups (25 in each). All patients will be recruited at a single site (University Hospital of Wales, part of Cardiff & Vale UHB). The study will investigate several feasibility measures including recruitment, delivery of the intervention (including device-related adverse events), acceptability and adherence to the intervention and sampling, use of Peptest to measure microaspiration events, rate of pepsin positive samples, rate of tracheobronchial colonisation, volume of sub-glottic aspirate, rate of VAP, length of ICU and hospital stay, demonstrate the validity of study documentation and provide preliminary data for 50 patients. The data will inform the pilot and main phase of the study.
Pulmonary Diffusion of Antibiotics in Patients Admitted for ARDS Following SARS-CoV-2 Pneumonia...
ARDSSARS-CoV 2 PneumoniaPatients on mechanical ventilation (MV) following SARS-CoV-2 pneumonia frequently develop ventilator-associated pneumonia (VAP). The incidence of MVAP during SARS-CoV-2 infections ranges from 50 to nearly 90%. In addition, up to 80% of recurrences of VAP (a new episode, most often attributable to the same bacteria) have been described, reflecting the failure of the initial antibiotic therapy. This incidence is much higher than that described for other etiologies of acute respiratory distress syndrome (ARDS). The investigators hypothesize that during VAP, there is an alteration of the diffusion of intravenous antibiotics in the lung parenchyma in COVID-19 patients in relation to several factors characteristic of SARS-CoV-2 infection. This altered diffusion may explain the high number of recurrences of MVAP compared to non-COVID-19 patients.
