Filter by:Covid-19 also primarily affects endothelium that line up the alveoli. The resulting hypoxemia may differ from "typical" Acute Respiratory Distress Syndrome (ARDS) due to maldistribution of perfusion related to the ventilation. Thus, pathophysiology of Covid-19 ARDS is different, which requires different interventions than typical ARDS. The investigators will assess whether extravascular lung water index and permeability of the alveolar capillary differs from typical ARDS with transpulmonary thermodilution (TPTD) technique. Extravascular Lung Water Index (EVLWI) and Pulmonary Vascular Permeability Index (PVPI) will be compared.
In order to safely and effectively reopen businesses and universities across the US, institutions will need to develop approaches to rapidly identify COVID-19 cases and manage their spread while balancing program effectiveness, feasibility, costs, and scalability. This study will evaluate the implementation of a COVID-19 screening program that coordinates several existing systems at the University of Pennsylvania including saliva-based viral testing.
Long-term outcomes from coronavirus disease 2019 (COVID-19) are currently unknown. This study will collect daily living status of survivors of COVID-19.
The primary aim of this study is to investigate the performance of Breath Biopsy RD for the detection of SARS-CoV-2 in both a clinical and at home setting.
Viral infections provoke the systemic inflammatory response and cause an imbalance between the procoagulant and anticoagulant homeostatic mechanisms. Multiple pathogenic mechanisms are involved, including endothelial dysfunction, increased von Willebrand factor, Toll receptor activation, and tissue factor pathway activation. D-dimer levels greater than 1000 ng / mL are associated with an 18-fold increased risk of mortality. In this context, many patients may require prophylaxis or antithrombotic treatment with low molecular weight heparins. Currently, there is no validated scheme on the dose and timing of the use of antithrombotic drugs. The study aims to identify the effect of two anticoagulant strategies (prophylactic and therapeutic) on the progression to ventilatory support or death in patients with COVID-19 infection who require hospital care.
This phase III trial aims to assess the efficacy, safety and immunogenicity of SARS-CoV-2 Vaccine (inactivated) and lot-to-lot consistency evaluation
The purpose of this study is to evaluate whether rivaroxaban reduces the risk of a composite endpoint of major venous and arterial thrombotic events, all-cause hospitalization, and all-cause mortality compared with placebo in outpatients with acute, symptomatic Coronavirus Disease 2019 (COVID-19) Infection.
In the late 2019 a new Coronavirus was identified as the cause of a group of atypical interstitial pneumonia cases in Wuhan, a city in the Chinese province of Hubei. In February 2020, the World Health Organization designated COVID-19 disease, which stands for Coronavirus 2019 disease. Following the progressive spread of the infection in other countries of the world, WHO declared the Pandemic on 11 March 2020. Italy was the first European country involved in the spread of the infection and among those with the highest number of victims. The Coronavirus responsible for COVID-19 has, as its main target organ, the respiratory system, being able to determine a serious acute respiratory syndrome similar to that of the cases found during the SARS epidemic of 2003: hence the name of the virus as SARS-CoV-2. The diagnosis of SARS-COV-2 infection is made by direct detection by PCR of viral RNA on different biological materials from patients with suspicious symptoms, and the first level diagnostic test is generally the nasopharyngeal swab. However, even if the specificity of the nasopharyngeal swab is high, its sensitivity can be affected by technical causes (sampling mode), as well as by intrinsic factors related to the method. The purpose of the study is to identify the clinical, laboratory and imaging characteristic which are similar or which can differentiate the hospitalized patients affected by COVID-19 pneumonia (with positive PCR on naso-pharyngeal swab) and patients with pneumonia with negative PCR for COVID-19. To do this, the investigators will compare the clinical, laboratory and imaging characteristics between interstitial pneumonia secondary to SARS-COV-2 infection, confirmed by molecular biology investigations (viral RNA research by PCR on nasopharyngeal swab) and cases of interstitial pneumonia negative to the nasopharyngeal swab.
The disease caused by SARS-CoV-2, has derived a pandemic in which its evolution and complications depend on the immune capacity of the host. The virus has been characterized by presenting an inflammatory cascade, increased by the overproduction of proinflammatory cytokines, the decrease in metalloenzymes and also the rapid spread of the virus. There are several lines of treatment, however, nutritional treatment only considered a caloric intake. For this reason, this study will evaluate the evolution of patients with COVID-19 assisted by nutritional support system and the effect of this therapy in reducing complications and comorbidities. Research question: Will the nutritional support system reduce complications in stage III positive COVID-19 patients with comorbidities (type 2 DM, SAH, overweight / obesity with BMI <35), with a better benefit than that achieved with the conventional nutritional treatment ?. Hypothesis: The nutritional support system will reduce the complications of patients with COVID-19 in stage III with comorbidities. General Objective: To determine the effect of the use of a nutritional support system on complications in patients with COVID-19 in stage III with comorbidities. Methodology: A controlled, blinded, randomized clinical trial will be conducted in patients with COVID-19, hospitalized at the ISSEMYM Toluca Arturo Montiel Rojas Medical Center, who meet the inclusion criteria. The evolution of the group of patients receiving the nutritional support system (NSS) and the normal diet implemented by the hospital will be evaluated against the group of patients receiving only the diet, using clinical examination, laboratory and cabinet tests during their hospital stay. Statistical analysis: for independent groups with normal distribution, Student's T will be applied. If the distribution does not meet normality criteria, a Mann Whitney U will be performed; Two-way ANOVA will be applied to monitor the groups over time with normal distribution. If the distribution does not meet normality criteria, a Friedman test will be performed, in both cases post hoc tests will be performed. The results will be analyzed using version 6 of the Graphpad Prism software.
Despite prophylactic anticoagulant treatments, thrombotic complications may develop in patients with Coronavirus disease 2019 (COVID-19). This study aimed to evaluate anti-Factor Xa levels to determine the anticoagulant activity of low molecular weight heparin (LMWH) in COVID-19 patients.
