Filter by:Project is designed as a comprehensive population-based epidemiological study in Upper-Silesian Conurbation (Poland) aiming at: 1. analysis of available data on incidence and mortality due to COVID-19 and 2. estimation of the occurrence of viral infection SARS-CoV-2 as revealed by the results of serological test (ELISA: IgM, IgG), with assessment of risk factors. The project's objectives are: to assess incidence and mortality due COVID-19 according to sex, age and coexisting diseases; to determine the level of potential "underdiagnosis" of the magnitude of COVID-19 mortality using vital statistics data for Upper-Silesian Conurbation; to assess the prevalence of SARS-CoV-2 based on the level of seropositivity in Upper-Silesian Conurbation; to identify host-related and environmental risk factors if the infection. Analysis of existing data will include monthly records on incidence and mortality over the period 01.01.2020-31.12.2020 and comparison of the findings with the monthly records of 2018 and 2019, for the same population. Cross-sectional epidemiological study will be located in three towne (Katowice, Sosnowiec, Gliwice). In each town a representative age-stratified sample of 2000 subjects will undergo questionnaire assessment and serological examination performed by serological test. The project corresponds with analogous population-based studies on COVID-19 in a number of countries and responds to the WHO recommendation in that field.
This study is designed as a multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the clinical efficacy and safety of MW33 injection in patients with mild or moderate COVID-19, and to evaluate its pharmacokinetic profile and immunogenicity.
It is expected that large numbers of healthcare workers will experience a broad range of psychological reactions and symptoms including anxiety, depression, moral distress, and trauma symptoms that will cause both significant suffering as well as occupational and social impairment. The purpose of this study is to find interventions which are helpful in treating psychological distress in healthcare workers caring for COVID-19 patients. There are two phases of the study. All participants will take part in Phase I, which consists of 4 sessions over a two-week period of either a narrative writing intervention or a medical music intervention. Participants will be randomly assigned to the narrative writing intervention or medical music intervention. After Phase I, participants will be re-assessed. Healthcare workers who meet criteria for PTSD will be given the option to participate in Phase II of the study, in which they will be offered a choice between one of two evidence-based treatments for PTSD: Interpersonal Therapy (IPT) or Exposure Therapy (ET). Both treatments are comprised of ten 75-minute sessions scheduled twice weekly. Participants will be allowed to choose a preferred treatment in Phase II. After Phase II participants will complete a final assessment concluding the study. All interventions will be offered using distance technology.
This study is to establish an accurate, robust and easily scalable COVID-19 viral nucleic acid analysis platform from, but not limited to, saliva to help enable and support contact tracing in the canton of Baselland/ Switzerland. To achieve this, crude ribonucleotide acid (RNA) extraction from saliva is validated in combination with next-generation sequencing (NGS) diagnostics and loop mediated amplification (LAMP) assays as well as point of care test (POCT) for rapid detection of viral antigens on patients' samples.
The investigators are conducting a pilot trial where they will study safety, efficacy and compliance in a cohort of ambulatory patients in the Ghent region with confirmed COVID-19 infection, in both an early stage of disease, defined as less than 5 days of symptoms and who at presentation do not meet any criteria for hospitalisation as well as asymptomatic individuals with a PCR CT value below 30. The primary endpoint is to assess the efficacy of the drug in terms of change from day 0 to day 5 in respiratory (oropharyngeal swab RT-PCR) log10 viral load. The aim of the study is to assess whether Camostat, a serine protease inhibitor available in an oral formulation has the potential to be studied as an antiviral drug in a large scale ambulatory setting to prevent transmission by decreasing viral load, to prevent symptoms after exposure (PEP) in asymptomatic individuals or to prevent disease progression in the occurrence of early symptomatology.
On 30 January 2020, WHO declared the SARS-CoV-2 outbreak as a public health emergency of international concern. Compared to SARS-CoV, which caused an outbreak of SARS in 2003, SARS-CoV-2 has a higher transmission capacity. Although the clinical manifestations of SARS-CoV-2 are dominated by respiratory symptoms, some patients have severe cardiovascular damage. In addition, patients with underlying cardiovascular disease may be at increased risk of death. Therefore, understanding the impairments caused by SARS-CoV-2 to the cardiovascular system and the underlying mechanisms is of the utmost importance. Circulating endothelial cells (CECs) are generally considered markers of lesions and may be non-invasive markers of pulmonary vascular dysfunction during SARS-CoV-2 infection. Another marker of endothelial activation could be circulating extracellular vesicles. They could also be involved in the spread of the virus. Thus this project proposes to study different aspects of the diagnosis and pathophysiology of SARS-CoV-2. We propose to fully study activation state of coagulation and endothelium on a plasma and cellular side in patients diagnosed with SARS-CoV-2/COVID19. The different forms of the disease will be included: without lung disease, with a more or less severe lung disease, i.e. having evolved or not towards acute respiratory distress syndrome (ARDS). Extensive research of biomarkers will be compared to the detection of the virus in the respiratory tract as well as in the blood. This work will contribute to a better description of disease pathophysiology and should allow us to identify a patient profile in whom preventive or curative anticoagulant therapy could be considered.
COVID-19 infection has been associated with numerous cardiac manifestations. Indeed, SARS-CoV-2 may impact on cardiovascular system through a direct myocardial infection or a secondary cardiac involvement due to hypoxia or metabolic supply-demand imbalance or prothrombotic inflammatory state. As a consequence of and besides acute myocardial damages, COVID-19 could also determine chronic cardiovascular consequences, with a significant impact on long-term prognosis, quality of life and functional capacity of COVID-19 survivors. On this basis, we aim to define the clinical and prognostic effects of myocardial involvement in COVID-19 patients.
Although recognized as an autoimmune disease the etiology of type 1 diabetes remains unknown. Virus infections has been suggested as a possible agent triggering the autoimmune reaction finally resulting in beta-cell destruction and fate of insulin secretion. SARS Cov-2 virus enters the infected cells by binding to the ACE-2 receptor, which is abundant in many tissues including the pancreas. Accordingly, SARS Covid-19 infection may trigger the development of type 1 diabetes either by an activation of the immune system or directly via beta-cell infection and destruction. Our aim is to study the impact of the Covid-19 epidemic on the development of type 1 diabetes. This will be done in two ways: a clinical study and an epidemiological follow up. During the next two years, adult patients with newly diagnosed type 1 diabetes will be asked to participate. Type 1 diabetes will be diagnosed by usual means and a mixed meal tolerance test will be performed at time of diagnosis and after one year to evaluate beta-cell function. People with type 1 diabetes and serologically documented previous SARS Covid-19 will be compared with people with no previous infection regarding beta-cell function and fate of insulin secretion. In addition, we will estimate the number of new diagnosed type 1 diabetes patients compared to previous years.
Study objective is to evaluate the efficacy of the combination of masitinib and isoquercetin in adult hospitalized patients with moderate and severe COVID-19.
Aim of the study is to verify the efficacy and safety of convalescent hyperimmune plasma infusion in hospitalized covid-19 patients non in ITU with pneumonia and respiratory symptoms within seven days from the beginning of symptoms. Efficacy is evaluated by the number of patients who will improve their clinical condition and will not be admitted to ITU. .Safety is considered in relation to adverse reactions to plasma infusion.
