Filter by:This pilot case-control study at Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sevagram, India is designed to evaluate the use of low dose radiotherapy (LDRT) in patients with moderate COVID-19 with specific objectives to abrogate the onset of cytokine storm and thus facilitate their early recovery and reduce mortality.
Severe COVID-19 is associated with a hypercoagulable state, with a high risk of thrombotic phenomena such as pulmonary thromboembolism (PE). Its diagnostic suspicion is complicated, due to the overlap of symptoms of PE with those of COVID-19 itself. Therefore, it is essential to improve PE prediction to optimise the performance of confirmatory imaging tests such as thoracic CT angiography. Early diagnosis has relevant therapeutic implications, as it justifies starting anticoagulant treatment early, with a possible positive impact on the clinical evolution of these patients. The CHOD risk scale has recently been described: the acronym for C-reactive protein concentration, heart rate, oxygen saturation, and D-Dimer levels. Its initial description was carried out in a study in a single hospital centre. proving to be an easy-to-apply tool, useful for predicting the appearance of PE in patients hospitalized for COVID-19. The objective of this study is to carry out an external validation of this scale in patients hospitalized for COVID-19 pneumonia, through an observational, cross-sectional, multicenter, real-life study in patients hospitalized for severe COVID-19 pneumonia, confirmed by objective methods, and showing high D-dimer values. Imaging tests with CT angiography will be performed in patients with elevated D-Dimer, following international clinical practice regulations. Given that they will be consecutive patients, CT angiography will be performed in all patients regardless of the patient's clinical probability of PE as long as they meet the inclusion criteria and none of the exclusion criteria. To calculate the PE predictive power of the CHOD scale in the validation cohort, a methodology similar to that used in the construction cohort will be used, that is, the use of a ROC curve. Taking into account that a similar predictive value (with a maximum error of 5%) between the CHOD scale in the construction cohort and that of this study (validation cohort) will be considered as an adequate external validation, and taking into account a statistical power of 80%, an alpha error of 5% and a maximum loss of patients of 15%, the required sample size is 245 patients. Since 7 centres initially participate, each of which will have to contribute 35 valid consecutive patients for the analysis.
The study investigates the role of positive pressure, inspired oxygen fraction and different decubiti (seated, supine, prone) on breathing effort (as assessed by esophageal pressure swings) in Covid-19 pneumonia (at different disease stages) and in other causes of respiratory failure. The hypothesis is that positive pressure might be deleterious in terms of breathing effort if the main pathological mechanism associated with Sars-CoV-2 infection in the lung is not alveolar damage (as in other causes of respiratory failure) but vascular impairment as previously reported. The effects of high inspired oxygen fractions and decubiti might also be different with respect to other causes of respiratory failure.
The incidence rate and mortality of lung infection are high worldwide. It is a common and frequently occurring disease which seriously threatens human health. Severe pneumonia accounts for 18-36% of all pneumonia. Severe pneumonia has caused serious economic and medical burden. Therefore, it is urgent to carry out the real-world cohort study of severe pneumonia. Big data and sample library will provide useful clinical guidance and scientific research reserves for clinicians. Through further research, we can improve the treatment success rate and reduce the mortality. The purpose of this study is to provide reliable biological samples and related data information for the relevant basic and clinical trials in the field of severe pneumonia by carrying out the construction of special disease cohort database and biological sample holographic database, and to establish a long-term sharing platform for the transformation of research results into clinical practice, improve the prognosis of severe pneumonia,and provide the evidence for improving the diagnosis and treatment of severe pneumonia suitable for China's national conditions.
A Double-blind, Multi-center, Multi-regional, Randomized controlled, Phase 3 Clinical Trial to Evaluate the Efficacy and Safety of CKD-314 in Hospitalized Adult Patients Diagnosed with COVID-19
This study is a multi-center, randomized, partially double-blind, and placebo-controlled Phase Ib clinical trial of inhaled CO (iCO) for the treatment of sepsis-induced acute respiratory distress syndrome (ARDS). The purpose of this study is to evaluate the safety and accuracy of a Coburn-Forster-Kane (CFK) equation-based personalized iCO dosing algorithm to achieve a target carboxyhemoglobin (COHb) level of 6-8% in patients with sepsis-induced ARDS. We will also examine the biologic readouts of low dose iCO therapy in patients with sepsis-induced ARDS.
Radiological and lung function recovery following Covid-19 infection.
Patients suffering from COVID-19 (Coronavirus Disease 2019) pneumonia are prone to bacterial and mycotic superinfection. According to existing evidence, the prevalence of superinfection is about 8% to 14% (95% CI 5-26%). However, the percentage of patients treated for superinfection is as high as 80%. There can be multiple reasons for this difference.
We will determine ventilator outcomes to Coronavirus Infectious Disease 2019 (COVID-19) using artificial Intelligence with inputs of chest radiographs and other evidence-based co-variates.
Up to 135 patients with hypersensitivity pneumonitis will be enrolled at 7 clinical centers across the United States. Patients will be followed for 24 months to determine if biomarkers in the blood can predict disease progression.
