Filter by:The purpose of this study is to develop and evaluate the usefulness of hyperpolarized (HP) 129Xe gas MRI for regional assessment of pulmonary function.
One lung ventilation (OLV) is essential during thoracic surgery. During OLV, intrapulmonary shunt can be increased resulting hypoxemia. Although OLV technique had been advanced so far, hypoxemia during OLV reaches about 10% in spite of inspired oxygen fraction 100%. Iloprost is a prostaglandin analogue used for pulmonary hypertension, which can decrease pulmonary artery resistance by selectively dilating pulmonary artery. In this prospective, randomized, double blind study, the investigator is planning to investigate the effects of iloprost on respiratory physiology (intrapulmonary shunt, deadspace, oxygenation, etc) in obese patients.
the study attempted to assess and evaluate the efficacy of implementing chest expansion exercises on patients with pleural effusion and how this programme contribute to reduce pulmonary infection and complications. To address the objective of the study, the researcher utilized chest expansion exercises consisted of stacked breathing exercise, segmental breathing, chest mobility exercises, deep breathing exercise with use of incentve spirometer and assess the patient before and after exercises by using three tools help to monitor hemodynamic parameters, chest condition, laboratory investigations which help to evaluate pulmonary infection score and complications.
Novel Coronavirus (2019nCoV) or Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) that causes Coronavirus Disease 2019, or known as Covid-19 has recently become a global health emergency since it was first detected in Wuhan, the People Republic of China in December 2019. Since then, the prevalence has rapidly increased worldwide. In Indonesia, by the end of April 2020, around 10,000 patients have been tested positive for Covid-19 infection, with a case fatality rate of around 8%. The pathogenesis of Covid-19 is still under investigation and to our understanding, ACE2 receptors in the alveoli serve as the binding site of the S-protein of envelope spike virus of SARS-CoV-2. TMPRSS2 enzyme aids the fusion between cell membrane and capsid of the virus, allowing penetration of virus into the cell. Vesicles containing virion fuse with cell membrane and released as new virions. Cytopathic effect of the virus and its ability to overcome immune response determines the degree of infection. Differences in immunological profile among degrees of severity of Covid-19 may vary especially for the number of pro-inflammatory cytokines such as tumor necrosis factor alpha (TNF-α), interleukin (IL)-1, IL-6, IL-8, leukemia-inhibiting factors (LIF), immunological markers such as CXCR3+CD4+, CXCR3+CD8+ T cell and CXCR3+ NK cells, implying the ongoing cytokine storm. The previous studies also found increasing number for infection markers such as procalcitonin, ferritin, and C-reactive protein. The decreasing number of anti-inflammatory cytokines in such as IL-10 also supports this finding. Previous studies have shown immunomodulating and anti-inflammatory capacity of the mesenchymal stem cells (MSCs). MSCs contributed to the shifting of pro-inflammatory Th2 into anti-inflammatory Th2. One of the most recent study on the usage of MSCs on Covid-19 patients showed increased expression of leukemia inhibitory factor (LIF), which give rise to inhibitory effect of T lymphocyte and natural killer (NK) cell population. Vascular epithelial growth factor (VEGF) is found increasing following MSCs administration, which indicates the ability to improve the disrupted capillaries due to SARS-Cov-2 infection. The ability of MSCs in differentiating to alveolar cells is proven by the presence of SPM and SPC2, surfactant proteins produced by type II alveolar cells. MSCs are unable to be infected by SARS-CoV-2 since they don't have ACE2 receptors and TMPRSS2 enzyme.
In light of the ongoing COVID-19 epidemic in Norway, it is paramount to develop and utilize clinical tools for assessing and risk stratifying patients with suspected coronary infection in the emergency departments. Diagnostic use of ultrasound in viral pneumonias, including COVID-19 has proved to be very useful. The use of ultrasound will assist in quick detection of lung pathology compatible with increasing severity of the COVID-19 disease. At the same time, the use of ultrasound diagnostics in the emergency department could improve logistics and reduce potential exposure of the corona virus to other health personnel. The purpose of the study is to assess whether ultrasound findings correlates with physical examination, labs, and other imaging diagnostics in patients with suspected or diagnosed COVID-19 disease, as well as assessing whether ultrasound diagnostics can assist in risk stratification. The project is conducted as a prospective multicenter study where ultrasound diagnostics will be performed on patients with suspected coronary infection in the emergency departments. Data collection takes place as part of the daily clinical evaluation of acute patients in the emergency departments. The project is planned to be completed towards the end of 2025.
This study is a phase II, parallel, prospective, randomized, double-blind, placebo controlled trial. The present study will aim to address the efficacy and safety of acute administration of triiodothyronine on ICU patients diagnosed with pulmonary infection due to COVID-19 and require mechanical respiratory support or ECMO.
Patients who are post hematopoietic stem cell transplantation who require a bronchoalveolar lavage (BAL) for standard clinical car will have extra fluid collected and sent for massively parallel sequencing to see if it is as sensitive for detecting a microbial pulmonary infection compared to standard cultures.
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.
Pneumonias and lower respiratory tract infections can have important long-term consequences, particularly in the context of lung transplantation, where pneumonia is a major cause of death. Candidate organs and lung transplant recipients undergo bronchoscopic inspection to assess for lower respiratory tract infection, but traditional culture methods take time, leading to increased risk from inappropriate therapy. The investigators hypothesize that the rapid detection of lower respiratory tract infection, using a semi-quantitative multiplex molecular assay, can decrease the time to appropriate clinical decision making.
Pulmonary infections remain the leading causes of morbidity and mortality among patients worldwide. Pathogen identification is crucial yet difficult for the majority of the cases. Metagenomic Next-generation Sequencing provides a potential technology for rapid and untargeted pathogen detection for pulmonary infection. The study is designed observationally to investigate if mNGS is superior to traditional paradigm of serial tests in the aspect of diagnostic performance. Patients whose primary diagnosis is pulmonary infetion and bronchoalveolar lavage fluid can be obtained will be enrolled. Both mNGS and traditional paradigm of serial tests wil be performed.
