Filter by:The pandemic of a new coronavirus SARS-COV-2, which causes COVID-19 disease, has spread rapidly and is a major public health challenge. While the focus is primarily on containing the number of cases and finding alternative therapies, information is still lacking to elucidate the dynamics of viral circulation and to understand the distribution of the infection in the population. The cases reported in Argentina and worldwide could plausibly represent only a small proportion of the number of asymptomatic or poorly symptomatic cases that exist in society. However, the magnitude of this dissociation between symptomatic cases and asymptomatic persons is unknown. Knowing this information is of strategic importance as it will allow the estimation of a community prevalence and the evaluation of the best containment strategy. In fact, although all social distancing measures are now indispensable, the feasibility of prolonging the measure over time is a complex issue and in any case will require population-based information. The best way to approach the estimation of a true population prevalence is to take representative samples from the population and test them periodically. These experiences were carried out in other contexts showing heterogeneous results within the community studied. In Spain, for example, the range of antibodies present in the population varied from 1.1% to 14.2%, also showing that an important part of the population had had contact with the virus without symptoms. Studies in Switzerland and the United States also show similar findings. However, these estimates are not automatically transferable to other settings. The city of Buenos Aires has a particular demographic composition with an important group of the population living in shantytowns (it is estimated that between 7% and 10% of the population lives in shantytowns) and with much heterogeneity among the different communes of the city. In the villas, the incidence rates of COVID-19 infection differ significantly from those present in the group "outside the village". However, there is also an important difference in the incidence rates by commune, even without considering the villas. Thus, it is important to know the sero-epidemiology of antibodies against SARS-COV2 in a representative sample of the city of Buenos Aires. For this purpose, a nationally produced test (COVIDAR IgG) developed by professionals from CONICET and Instituto Leloir will be used. The aim of this initiative is to estimate the true dimension of the COVID-19 epidemic in the City of Buenos Aires, by studying the immunological status of the Buenos Aires population in relation to SARS-Cov2, as well as to observe the evolution of the infection among the population, since this information is essential to guide future public health measures related to the control of COVID-19. To achieve this objective, a comprehensive sero-epidemiological study will be carried out to provide estimates of past SARS-Cov2 infection with sufficient precision to be representative of the sero-epidemiological status of the Buenos Aires city population.
COVID-19 morbidity and mortality has been associated with Cytokine Release Syndrome (CRS) and Acute Respiratory Distress Syndrome (ARDS). ATI-450 is an oral small molecule MAPKAPK2 (MK2) inhibitor that potently inhibits multiple inflammatory cytokines. The investigator hypothesizes that MK2 pathway blockade during active COVID-19 infection in hospitalized participants will result in improvement in respiratory-failure free survival.
Only 5% of patients infected with COVID-19 develop severe or critical Coronavirus disease 2019 (COVID-19) and there is no reliable risk stratification tool for non-severe COVID-19 patients at admission. Finding a way to predict which patients with an initial mild to moderate presentation of COVID-19 would develop severe or critical form of COVID-19 according to CT-scan data, simple clinical and biological parameters is challenging. In this multicentric study, the study aims to construct a predictive score for early identification of cases at high risk of progression to moderate, severe or critical COVID-19 combining simple clinical and biological parameters and qualitative, quantitative or artificial intelligence (AI) data from the initial CT from non-severe patients.
The COVID-19 pandemic is of grave concern due its impact on human health and on the economy. Propolis, a natural resin produced by bees from plant materials, has anti-inflammatory, immunomodulatory, anti-oxidant properties, and various aspects of the SARS-CoV-2 infection mechanism are potential targets for propolis compounds. Propolis components have inhibitory effects on the ACE2, TMPRSS2 and PAK1 signaling pathways; in addition, antiviral activity has been proven in vitro and in vivo. This is a pilot randomized study that aims to assess the impact of using Brazilian green propolis extract against the deleterious effects of the new coronavirus.
We have herein analysed the patients admitted to our Department that underwent serologic tests for SARS-CoV-2 either by Ab or RT PCR, to estimate the prevalence of COVID-19 in the setting of a non-dedicated COVID-19 hospital and in a low CoV-2 incidence area, and to evaluate if security measures are necessary for this context.
COVID-19, which emerged in China in December 2019, has become a pandemic with its spread to many countries of the world. Although it is suggested that hospital admissions are reduced due to some reasons such as trauma, during COVID-19 pandemic, it is controversial whether in-hospital mortality rates changed. Therefore this multi-centered study aimed to determine how in-hospital mortality effected during the pandemic period according to the specific patient groups.
The purpose of the study is to determine if a high dose of Intravenous Immune Globulin (IVIG) plus Standard Medical Treatment (SMT) can reduce all-cause mortality versus SMT alone in hospitalized participants with COVID-19 requiring admission to the ICU through Day 29.
Coronavirus disease 2019 (Covid-19) has been declared global emergency with immediate safety, preventative and curative measures to control the spread of virus. Confirmed cases are treated with clinical management as they are diagnosed but so far, there is no effective treatment or vaccine yet for Covid-19. With recommended guidelines of AYUSH Ministry, India, the use of Ayurveda for Covid-19 has increased; however, its efficacy and safety in Covid-19 confirmed patients remain unclear. Present study examined the efficacy and safety of one of the recommended Ayurveda drug (Guduchi Ghan Vati) compared with standard care for patients with asymptomatic Covid-19 patients.
COVID-19, which emerged in China in December 2019, has become a pandemic with its spread to many countries of the world. Emergency departments also carried out an important part of the fight against pandemics in our country/Turkey. The emergency department including an intensive care unit is very few in this country/Turkey and the only hospital, which has an Emergency Intensive Care Unit (EICU) in Istanbul, is the study center. Therefore, this retrospective study aimed to provide useful information about how an effective EICU should be, especially how to use them during pandemic periods.
This is a phase 1 study in which healthy adult volunteers will receive BRII-198 or placebo and will be assessed for safety, tolerability, and pharmacokinetics.
