Dräger COVID-19 Antigen Test Clinical Performance Study
Covid19The study is designed to demonstrate suitability of the Dräger Antigen Test for SARS-CoV-2 detection in clinical nasal specimens. Real-time polymerase chain reaction (RT-PCR) on specimens collected by pharyngeal swabs serves as a reference method.

COVIDISC: Rapid Diagnostic Tests on Nasopharyngeal Swabs for the Detection of COVID-19
COVID-19SARS-CoV-2The Covid-19 pandemic requires a reliable diagnosis of patients in order to take care of them in the best conditions and in the appropriate services. Moreover, the current diagnostic reference is reverse transcription by polymerase chain reaction (RT-PCR) on a nasopharyngeal sample taken by swab. This technique is expensive (54€) and its production time is several hours. Alternative methods are in progress, including, rapid diagnostic tests. The MEMS microfluids and nanostructures (MMN) laboratory, in partnership with the Institut Chimie Biologie Innovation (CBI) (Paris, 75005), have developed a portable test "COVIDISC", low-cost (10 €), fast (1 hour), including extraction, elution and amplification in solid medium isothermal, reverse amplification loop mediated transcription (RT-LAMP). The "lab" version has received an analytical validation on human nasopharyngeal samples with performance comparable to classic RT-PCR (sensitivity of 7 copies per μl, specificity 100%). The objective of this study is to validate the in vitro diagnostic medical device, COVIDISC, with the standard nasopharyngeal RT-PCR test.

A Study of DWJ1248 in Prevention of COVID-19 Infection After the Exposure of SARS-COV-2
Covid19SARS-COV-2 InfectionTo evaluate the prevention of SARS-COV-2 infection after administration of DWJ1248 in person who contact from COVID-19 confirmed patient compared to the placebo.

Multiple-Center Retrospective Study of Severe and Critical COVID-19 in Shanghai
COVID-19This study is to clarify the clinical characteristics of severe and critical COVID-19 from March 1st ,2022 to June 9th, 2022 in Shanghai and to explore the relationship between the characteristics and prognosis in these patients.

Bicalutamide to Block TMPRSS2 in Males With COVID-19 Infection
COVID-19COVID-19 outcomes are worse in male patients. Androgen signaling, therefore, is a target for clinical exploration. TMPRSS2 is a membrane protease required for COVID pathogenesis that is regulated by androgens. Blocking TMPRSS2 with bicalutamide may reduce viral replication and improve the clinical outcome. Therefore, the study proposes to test bicalutamide at 150 mg oral daily dosing in a double-blind placebo-controlled randomized trial in male patients with early symptomatic COVID-19 disease.

Coronavirus Disease (COVID-19)The primary objective of this early Phase 1/2 study is to identify the V591 dose that achieves the target immune response in humans based on preclinical or early clinical data.

The Effect of Covid-19 Vaccination in Patients Undergoing IVF
Covid-19 VaccinationSince emerging in the last months of 2019, over 127 000 000 individuals have suffered severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection, and the documented death toll from coronavirus disease 2019 (COVID-19) had reached 2788639 individuals globally by the end of March 2021 (CDC, 2021).It is hoped that widespread vaccination will further limit viral spread and shorten the length of the pandemic and its impact on morbidity and mortality. There are currently two vaccines against the new coronavirus: inactivated vaccines and mRNA vaccines.Nationwide anti-COVID-19 vaccination began in China in March 2020, using the inactivated vaccine. By the end of September 2021, 2206.054 million doses (including the first and second doses of the vaccine) of the vaccines have been fulfilled.There is still a lack of real-world data to assist clinicians in counseling their IVF patients regarding the possible impact of recent recovery from COVID infection, or vaccination against it, on the potential for success of ART. We aimed to determine the impact of confirmed COVID-19 immunization on IVF outcomes, by comparing live birth rate of the first transfer cycle in patients undergoing IVF with and without COVID- 19 vaccination.

The Effect of the COVID-19 Epidemic Process on the Nutritional Habits and Body Weights of Adults...
COVID-19 PandemicEating Habit1 moreDuring the COVID-19 epidemic, the time spent by adults on the stomach has increased. Therefore, the likelihood of adverse changes in lifestyles has increased. In this study, the changes in nutritional habits, physical activities and body weights of adult individuals during the epidemic will be evaluated. A questionnaire including questions about nutritional habits, physical activity status and changes in body weights will be administered to individuals. The results will be evaluated with the appropriate statistical method. The survey will be administered once. The estimated time to reach the total number is 3 months.

SeroprevalenceAntibody1 moreThis study is the second cross-sectional study conducted in the region. In the first cross sectional study, conducted in the winter of 2020, we aimed to estimate the seroprevalence of SARS-CoV-2 IgG antibodies among blood donors in Sarajevo Canton. We also assessed immune durability among seropositive participants after 6 months. In total, of 1015 blood donors aged 18-65 years in Sarajevo Canton between 2 November and 3 December 2020 were recruited and population-weighted seroprevalence in Sarajevo Canton was 19.2% (95% CI: 16.7-21.6%). The aim of this second cross-sectional study is to measure the seroprevalence SARS-CoV-2 antibodies and assess antibody kinetics in the blood donor population after 12 months.
