Filter by:In order to verify the clinical value and safety of Xiyanping injection in children with CAP, we intend to carry out this multi-center, large-sample, non-intervention clinical research through more rigorous and scientific design. Considering the current status of clinical research in children in China,research use real-world research methods.
Community acquired pneumonia (CAP) is a common respiratory infection and is the main cause of ICU admission and death in adults. Because of most patients were treated empirically against suspected causative microorganism, it is important to assess the effectiveness of treatment after 3 days of anti-infective therapy. However, the criteria for treatment failure is lack of a clear-cut and validated definition from the CAP guidelines. Pneumonia severity scores is a wide-used severity rating system for treatment selection and outcome prediction for CAP. So far, the pneumonia severity scores only used once before the treatment started. Considering the pneumonia severity scores could reflect the severity of pneumonia, it is reasonable to assume that the change of pneumonia severity scores could reflect the patients' condition and the effectiveness of the treatment. This trail will be designed to validate the feasibility of assessing effectiveness of CAP treatment by using continuous pneumonia severity score.
This study will assess the role of pentraxin3 (PTX3) in the early diagnosis of ventilator-associated pneumonia (VAP) and the detection of antibiotic sensitivity for different organisms isolated from tracheal aspirate.
Sunnybrook Veterans Centre (VC) is a long-term care (LTC) facility with many elderly residents living with swallowing disorders who are at high risk of developing pneumonia from aspirating food/liquid into their lungs. Expiratory muscle strength training (EMST) using a hand-held resistance device over a four week intensive program has been shown to have promising results in improving cough function and reducing aspiration during swallowing in older, community-dwelling adults. The purpose of this study is to explore whether a modified slow-stream protocol of EMST over eight weeks is an effective therapy for improving swallowing safety and lung clearance in elderly VC residents with swallowing disorders. Before and after the eight week therapy program, we will measure participants' cough under spirometry, swallowing under videofluoroscopy, and their swallowing-related quality of life and diet texture modification. A three month follow-up visit will measure swallowing-related quality of life again, as well as record incidence of respiratory tract infections requiring antibiotics in the last three months, to be compared with broader institutional data.
To evaluate the sensitivity, specificity and diagnostic accuracy of bedside transthoracic ultrasound examination in the diagnosis and follow up of ventilator associated pneumonia.
Sepsis is a dysregulated host response to severe life-threatening infections, leading to organ failure and death in up to 40% of patients with septic shock. Pulmonary infections are the main cause of community-acquired sepsis and frequently lead to the development of acute respiratory distress syndrome(ARDS). Features of immunosuppression, including diminished cell surface monocyte human leukocyte antigen DR (mHLA-DR) expression, are strongly associated with hospital mortality. Such decrease in HLA-DR expression on antigen-presenting cells has been associated with impairment of microbial antigens to Tcells. Septic patients also show elevated expression of inhibitory receptors associated with cell exhaustion.. Yet, biochemical, flow cytometric and immunohistochemical findings consistent with immunosuppression have been observed in lungs and spleen of patients died of sepsis and multiple organ failure, demonstrating the relevance of studying these defects directly in organ tissues. A novel approach aimed to characterize the role and prognostic value of alveolar biomarkers measured directly in the injured lungs is warranted and supported by: -disappointing results of previous clinical trials attempting to restore the level of biomarkers measured on circulating cells; -evidences of regional immunosuppression in lungs of ARDS patients; -lung is the main site of hospital-acquired infections with a prevalence of ventilator-associated pneumonia in 30% over the course of Intensive Care Unit(ICU) stay in ARDS patients. Investigators speculate that biomarkers measured on alveolar leukocytes (AL) surface, are important predictors of outcome and potential therapeutic targets in ICU patients with pneumonia-associated ARDS. Investigators aim to explore whether biomarkers measured directly on AL from patients with pneumonia-associated ARDS are associated to regional pulmonary immunosuppression using leukocyte functional tests; and predictors of outcomes. Bronchoalveolar lavage fluid(BALF) and blood samples will be collected in ARDS patients. Leukocyte populations and cell membrane biomarkers will be quantified using flow cytometry. Leukocyte functional tests will be performed ex vivo on leukocytes collected from BALF and blood samples. Pharmacological interventions will be performed ex vivo. This project aims to identify biomarkers associated with outcomes and potential therapeutic targets.
The incidence and prevalence of pulmonary disease due to Non-tuberculous mycobacteria (NTM) is increasing worldwide, and this trend has been confirmed in Korea. Treatment of NTM pulmonary disease is difficult and usually requires more than two years of long-term treatment, and the antibiotic regimens used in treatment vary. Therefore, it is difficult to track the natural history of patients with NTM pulmonary disease, to evaluate the treatment outcome, and to understand the effect of specific medicines on the outcome. Establishing a prospective registry of patients with NTM pulmonary disease is expected to accurately evaluate the progress, treatment modality, and treatment outcome of NTM pulmonary disease.
Enrollment criteria and clinical data collection: follow the principles of medical ethics, the development of inclusion and exclusion criteria, Select all eligible patients with severe pneumonia(SP) who were admitted to the hospital during the study date.The diagnostic criteria we will use for SP are based on the Infectious Diseases Society of America/American Thoracic Society guidelines.Primary outcome measures：a.CURB-65 Score for Pneumonia Severity;b.The changes in inflammation and coagulation indicators: C-reactive protein, procalcitonin, and d-dimer;c.Chest x-ray changes;d.Mortality rate after 28 days;e.The time of mechanical ventilation, total duration of ICU stay, hospitalization, and antibiotic use;f.The time of bacterial cultures becoming negative;g.Daily sputum drainage.The aim of this study is to evaluate the anti-infective effectiveness and safety of prone position drainage compared with supine position on SP treatment.
Radical radiotherapy is the main treatment of locally advanced lung cancer, and radiation pneumonia is the main toxic effects of radiotherapy. Among them, the fatality rate of severe radiation pneumonia can reach 50%, which is very harmful to tumor patients. At present, the treatment mode of radiation pneumonia is very few, and the therapeutic effect is poor. The prevention of radiation pneumonitis may be the best way to reduce the number of patients with Post-radiotherapy pneumonia. Previous small clinical studies have shown that the incidence of radiation pneumonia in inhaled beclomethasone group (2 /28) was significantly lower than that in oral prednisone group (8 /29) during radiotherapy. The purpose of this study was to compare the efficacy and safety of radiotherapy between the therapeutic group (inhaled beclomethasone during radiotherapy) and the control radiotherapy group (patients received radiotherapy only), especially the incidence of radiation-induced pneumonia within half a year.
The purpose of this study is to determine the efficacy of intermittent subglottic secretion lavage combined with aspiration preventing ventilator associated pneumonia in patients with severe neurological disease
