Filter by:The global pandemic COVID-19 has overwhelmed the medical capacity to accommodate a large surge of patients with acute respiratory distress syndrome (ARDS). In the United States, the number of cases of COVID-19 ARDS is projected to exceed the number of available ventilators. Reports from China and Italy indicate that 22-64% of critically ill COVID-19 patients with ARDS will die. ARDS currently has no evidence-based treatments other than low tidal ventilation to limit mechanical stress on the lung and prone positioning. A new therapeutic approach capable of rapidly treating and attenuating ARDS secondary to COVID-19 is urgently needed. The dominant pathologic feature of viral-induced ARDS is fibrin accumulation in the microvasculature and airspaces. Substantial preclinical work suggests antifibrinolytic therapy attenuates infection provoked ARDS. In 2001, a phase I trial 7 demonstrated the urokinase and streptokinase were effective in patients with terminal ARDS, markedly improving oxygen delivery and reducing an expected mortality in that specific patient cohort from 100% to 70%. A more contemporary approach to thrombolytic therapy is tissue plasminogen activator (tPA) due to its higher efficacy of clot lysis with comparable bleeding risk 8. We therefore propose a phase IIa clinical trial with two intravenous (IV) tPA treatment arms and a control arm to test the efficacy and safety of IV tPA in improving respiratory function and oxygenation, and consequently, successful extubation, duration of mechanical ventilation and survival.
The primary objective of this research study is to assess Radiation Oncology healthcare providers (i.e. faculty, residents and advanced practice providers (APPs) implementation and perception of telehealth for on treatment patients in lieu of in person on treatment visits during standard of care radiotherapy during COVID-19.
Coronavirus disease 2019 (COVID-19) ,caused by the newly identified Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus, has shown substantial global spread affecting over 2 million people and claiming over 120,000 lives to date. In March 2020, the World Health Organization (WHO) declared COVID-19 a global pandemic. The spectrum of manifestations of COVID19 infection ranges from mild flu-like symptoms to severe acute respiratory distress syndrome (ARDS), with an associated fatality rate of 1.4%. The suggested mode of entry of the SARS-CoV-2 into the human respiratory epithelium is through the angiotensin-converting enzyme 2 (ACE2) protein expressed on alveolar cell surfaces. This entry mechanism has sparked the interest of the scientific community. Preliminary epidemiological reports showed an increased risk of ARDS in hypertensive COVID-19 patients. This leads to the hypothesis that hypertensives treated with angiotensin-converting enzyme inhibitor (ACE-I) are at an increased risk of developing complicated COVID-19 infections . Other studies have refuted these claims as unsupported. Studies revealing the up regulation of ACE2 in cells of patients treated with ACE-I or ARBs were the underlying foundation for these claims. This study aims to assess the impact of ACE-I and/or ARBs on the prognosis of patients with COVID19.
The COVID-19 outbreak is associated with a surge in ICU bed requirement and substantial mortality (estimated between 0.5% and 1%). Admission in the intensive care unit (ICU) and need for mechanical ventilation is reportedly associated with an estimated hospital mortality of more than 30%. Furthermore, the surge in ICU bed requirement is a worldwide-shared issue, leading to sub-optimal ICU management. In acute respiratory failure due to COVID-19-related pneumonia, vasoplegia with vascular enlargement inside the lung lesions and dilation of small vessels seen on chest CT scan largely account for severe hypoxemia whose physiological response is hyperventilation leading to hypocapnia. Almitrine, initially described to reduce intrapulmonary shunt by enhancement of hypoxic pulmonary vasoconstriction in combination with inhaled nitric oxide (iNO), redistributes pulmonary blood flow from shunt areas to lung units with normal ventilation/perfusion (VA/Q) ratio. Low dose of intravenous almitrine (2 µg.kg-1.min-1) alone also improves oxygenation (without combination with iNO) by selective pulmonary vasoconstriction of precapillary pulmonary arteries perfusing lung areas exposed to a hypoxic challenge with a slight increase in mean arterial pulmonary. Therefore, our hypothesis is that 5 days of low dose of almitrine therapy may improve the ventilation-perfusion (VA/Q) ratio at a relatively early stage of this specific lung disease and limit respiratory worsening and subsequent need for mechanical ventilation.
The purpose is to demonstrate the efficacy of low-dose interleukin 2 (Ld-IL2) administration in improving clinical course and oxygenation parameters in patients with SARS-CoV2-related ARDS.
The study aims to identify COVID 19 knowledge, working conditions, perception of anxiety and stigma among Egyptian health care providers as well as their predictors.
The purpose of the investigators is to study the psychological impact of the COVID-19 lockdown on the members of the Ville Evrard Hospital staff and their close relatives, and to identify potential lockdown conditions that could increase anxiety, anger and depressive symptoms in this population.
In the SAVE study patients with lower respiratory tract infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at high risk for progression to serious respiratory failure will be detected using the suPAR biomarker. They will begin early treatment with anakinra in the effort to prevent progression in serious respiratory failure.
The aim of this study is to evaluate the efficacy of pulmonary physiotherapy on respiratory functions in hospitalized patients with Novel Coronavirus 2019 pneumonia. Patients will be randomized into 1) intervention group: receiving pulmonary physiotherapy technique to improve pulmonary function and walking training or 2) control group: Usual medical care. Patients in both groups will receive therapeutic incentive spirometer. Various outcome measurements of pulmonary functions will be evaluated before and after of interventions. Mortality rate, hospitalization duration and re-admission will be followed until one month after end of intervention. Also, patient's quality of life will be measured after one month.
The present Diagnostic Accuracy study aims at experimentally validating the use of a rapid salivary test to detect SARS-CoV-2 infection in both symptomatic and asymptomatic individuals as a preliminary approach to a mass screening program. The study is based on a consecutive recruitment of both patients showing symptoms probably associated with COVID-19 (i.e., cough, dyspnea, fever) and asymptomatic patients with a low risk phenotype. The expected number of recruited individuals is 100. The experimental test is a prototype of salivary test based on the Lateral Flow Immunoassay technique and is able to detect the presence of SARS-CoV-2 in saliva, especially the Spike protein (S). The comparison is represented by the nasopharyngeal swab, the gold standard of COVID-19 diagnosis. Patients will undergo both salivary immunoassay and nasopharyngeal swab, thus the outcome assessors are blinded, since the results of the rRT-PCR analysis require at least 6 hours before being available. The main outcomes are sensibility and specificity of the rapid salivary test, when compared with the gold standard (nasopharyngeal swab).
