Systematic Offer of Nurse-Driven Screening for COVID-19 in Emergency Departments in the Paris Metropolitan Area, DEPIST-COVID

European countries faced another wave of the SARS-CoV2 pandemic, which has led to a second lockdown in France in November 2020 in order to avoid overwhelming health services. To prevent or reduce another wave, the strategy calls for vaccination, maintaining barrier measures and testing and isolating infected persons in order to break the cycles of infection. The latter objective is made difficult by the existence of asymptomatic carriers or symptomatic carriers that have very few symptoms and that aren't tested. Identification of these carriers in the general population is usually based on a search for close contact persons from those who were tested positive or from identified clusters. Experiments of mass testing are being carried out or were carried out, for example in Liverpool or Slovakia but, in order for them to be effective, they must be repeated, which limits feasibility. Another strategy of wide screening in the general population to identify asymptomatic persons is to offer a systematic screening during medical consultations and particularly in the emergency departments (ED). This strategy grants access to the entire population attending health facilities, including persons with lower income. This strategy can be conducted continuously in order to: 1) contribute to controlling the epidemic by identifying and isolating asymptomatic persons and their close contacts; 2) provide an observatory on the evolution of viral circulation in the general population. To the best the knowledge, this strategy has not been evaluated and will be tested it in 18 emergency departments in the Paris Metropolitan area, one of the most SARS-CoV2 affected regions. The aim is to evaluate the benefit of a systematic offer of SARS-Cov2 screening by rapid testing (molecular multiplex PCR/ RT-LAMP) to identify infected persons, associated with the usual practice of the EDs (intervention strategy) compared to a period based on usual practice of the EDs (control strategy) The strategies will be compared during two periods following a cluster-randomized two-period crossover design. During intervention periods, nurses will suggest performing a SARS-CoV2 test to patients using a PCR multiplex for symptomatic patients and a RT-LAMP for asymptomatic patients.

SARS-CoV-2 (COVID-19) Longitudinal Study: Understanding Susceptibility, Transmission and Disease Severity (Legacy Study)

The study aims to investigate SARS-CoV-2 susceptibility, transmission and disease severity in healthcare workers and patients. Residual specimens from an existing collection of samples in viral inactivating buffer and derivatives and serum from the Crick COVID-19 Consortium Testing centre (Cohort A1) and additional biological material collected prospectively (Cohorts A2 and B) will be used for research into SARS-CoV-2 transmission, evolution and immune control. This testing centre is a partnership between UCLH and The Francis Crick Institute to provide COVID 19 RT PCR testing for healthcare workers (HCWs) and patients in London Hospitals and care homes. A third group (Cohort C) of the study will allow for collaborative work with other REC approved research studies that have used the Crick COVID-19 Consortium Testing centre and will involve the use of study samples already collected from each study to be analysed under the SARS-CoV-2 Longitudinal Study end points

COVID-19 Contact Study by Antigen Detection Test

Stopping the SARS-CoV2 spread is essential to control the pandemic cause by this virus. A great effort is being made to carry out surveillance, case detection and contact control protocols in order to detect and isolate those contagious subjects. Since both symptomatic and asymptomatic subjects can be contagious, a surveillance system based on the presence of symptoms is not enough, requiring to perform diagnostic tests in a large number of subjects, such as asymptomatic contacts or high-prevalence populations, and repeatedly. Moreover, the speed in obtaining results is crucial in order not to delay the isolations of positive subjects. The polymerase chain reaction (PCR) is an expensive test which requires specialized equipment and personnel with a delay in results of 24-48 hours. In addition, its high sensitivity can mean that subjects without infective capacity have a positive result. In contrast, antigen detection tests (ADTs) are cheap and easy to perform, having a result in few minutes. They have shown high sensitivity and specificity in symptomatic subjects, specially in the first week of symptoms when the viral load is high. This could be very useful for the study of asymptomatic contacts to detect those with potential contagiousness quick, easily and cheaply. However, there is no evidence to support the use of ADTs in this group of subjects. For this reason, the investigators propose to carry out a study to compare the diagnostic efficacy of ADTs versus PCR in the group of subjects considered to be close contacts of SARS-Cov2 positive patients in the health area of Cáceres.

Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) Immune Kidney Transplant Study (COVID-19)

None of the vaccines approved, or in clinical trials, have so far been tested on transplanted patients. If they produce an immune response to the Spike protein of SARS-CoV-2 it is unknown how long the protective immunity will last. Not all immune responses are equal. The investigators will quantify immune cell subsets with flow and mass cytometry analyses to describe the phenotype of responding immune cells, including specific T cells. If not already established, patient human Leukocyte antigen (HLA) genotypes will be typed. In order to compare the immune responses with healthy individuals a control group of hospital employees will be included and sampled before and after vaccination according to the same time schedules as the kidney transplanted patients.

Electrocardiogram Analysis in COVID-19 Patients

Electrocardiographic (ECG) evaluation of patients with severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection. The present study involves three different phases of evaluation of the ECG traces of hospitalized patients with SARS-CoV-2 infection. Phase 1: it is proposed to collect and retrospectively analyze the ECGs of hospitalized patients with severe SARS-CoV-2 infection which led to invasive ventilation or patient death as a consequence and, if available, also possible troponin dosage; Phase 2: aims to collect and analyze the ECGs of consecutive hospitalized patients with SARS-CoV-2 infection and evaluate their relationship with the course of the disease, cardiac involvement and prognosis; Phase 3: it is proposed to repeat ECG and to carry out echocardiogram to patients with SARS-CoV-2 infection after 3 months from hospital discharge by simultaneously performing, if deemed clinically indicated, also cardiac magnetic resonance. In this phase, any evolutions of ECG alterations of the acute phase will be described and the relationship with cardiac involvement will be assessed.

Sero-prevalence COVID-19 Among Belgian Children

Based on studies in China, Iceland, the Netherlands and Italy it seems that children are less affected by SARS-CoV-2 infections and play a lesser role in the dissemination of the SARS-CoV-2 virus. It is unclear to which extend this is due to lesser exposure or an inherent decreased susceptibility to become infected. The low reported number of cases in children can be partially explained by the lower testing rates in the pediatric population. To get insight in the transmission of SARS-CoV-2 virus in school-aged children it is necessary to compile data on infection of SARS-CoV-2 virus in the child and (pre-)adolescent population. The main objective of this study is to determine the sero-prevalence and sero-conversion of antibodies against SARS-CoV-2 in a sample of school-aged children (primary and secondary school) in Belgium at different time points. Additionally this study will gain insight in the incidence of SARS-CoV-2, the proportion of asymptomatic infections with SARS-CoV-2 and the role of COVID-19 infection in household members. It will give us the possibility to investigate potential risk factors for infection. The study population includes primary and secondary school children from two predefined age groups (8-9 and 13-14 years old). These two groups are chosen because studies have shown more pronounced symptoms of infection and disease depending on age and because transmission dynamics also vary by age. The study population will be recruited in all Belgian schools including Brussels-Capital, Flemish and Walloon Region (including the German speaking community). The study is a prospective cohort study. In total there will be 3 testing points with 3 months between each point. The sample size calculation indicated the inclusion of 41 randomly selected primary and 41 secondary schools and in each school 20 randomly selected pupils of the defined age groups. Parents/legal child caregiver will complete a questionnaire at each of the testing points providing basic socio-demographic characteristics (at baseline only) and risk-behavior and health characteristics including presence of symptoms during the time since the previous testing point (at each of the testing points). The questionnaire will be completed through a secured online application during the same week as the child had the saliva sample for serological testing taken. Saliva samples will be sent to the Sciensano laboratory for serological analysis. The child's parent/legal caregiver will be informed of the serological result. Study data will guide the Belgian policy makers in their advices to limit circulation of SARS-CoV-2 in Belgium and more specifically in their advice on measures for school-age children. This data might also be used to guide health authorities that have to decide on vaccination strategies once a vaccine is available; to decide whether children should be included for vaccination to create herd immunity or not.

Hydroxychloroquine and Lopinavir/ Ritonavir to Improve the Health of People With COVID-19: "The Hope Coalition - 1"

The COVID-19 pandemic has been characterized by high morbidity and mortality, especially in certain subgroups of patients. To date, no treatment has been shown to be effective in controlling this disease in hospitalized patients with moderate and / or severe cases of this disease. Hydroxychloroquine and lopinavir / ritonavir have been shown to inhibit SARS-CoV viral replication in experimental severe acute respiratory symptoms models and have similar activity against SARS-CoV2. Although widely used in studies of critically ill patients, to date, no study has demonstrated its role on the treatment of high-risk, newly diagnosed patients with COVID-19 and mild symptoms.

COVID-19-Related Health and Practices Among Dental Hygienists

As dental practices reopen their practices during a global pandemic, the risk of 2019 novel coronavirus (COVID-19) infection that dental hygienists face in providing dental care remains unknown. Estimating the occupational risk of COVID-19, and producing evidence on the types of infection control practices and dental practices that may affect COVID-19 risk, is therefore imperative. These findings could be used to describe the prevalence and incidence of COVID-19 among dental hygienists, determine what infection control steps dental hygienists take over time, describe dental hygienists' employment during the COVID-19 pandemic, and estimate whether infection control adherence in dental practice is related to COVID-19 incidence.

COVID-19 Infection and Fetal-neonatal Outcomes

COVID-19, the coronavirus responsible for the pandemic that began at the end of 2019 in China, spreads through respiratory droplets and direct contact. The most common symptoms of the disease include fever, cough, asthenia or myalgia, wheezing and headache, and the most serious complication is acute respiratory distress syndrome (ARDS). The new coronavirus has continued to spread to multiple countries and continents so much so that the epidemic was declared a Public Health Emergency of International Interest (PHEIC) by the World Health Organization (WHO) on January 30, 2020. In the first phase of emergency worldwide, characterized by high morbidity and mortality, scientific interest has been mainly directed to the study of the transmission mechanisms of the infection, diagnostic tools and therapies for ARDS, especially in elderly and co-morbid patients. Interest has rapidly spread to other categories of patients and in particular to pregnancy, on which the virus could impact in different ways, with consequences for both the mother and the fetus. A recent systematic review that included all published reports on Coronaviruses (COVID-19, SARS, and MERS) in pregnancy showed that preterm delivery is the most frequently reported adverse event in these women, and that COVID-19 is associated with an increased risk of preeclampsia and caesarean section. Nonetheless, the limited sample size, the main inclusion of cases reported for acute respiratory symptoms, the lack of information on previous pathologies potentially capable of complicating pregnancy, do not allow for the extrapolation of strong evidence on the course of infection in pregnancy. Therefore, the current status of the scientific literature does not allow for general and wide-ranging implications. THe investigators therefore believe it is particularly useful to investigate maternal and fetal outcomes in this new broader scenario, including all pregnancies associated with asymptomatic or symptomatic SARS-CoV-2 infection, found in any gestational period, in order to evaluate in a "real world scenario" "Actual rates of maternal-fetal and neonatal adverse events

Use of Hypochlorous Acid as Prophylaxis in Health Personnel at High Risk of Infection by SARS-CoV 2 (COVID19)

The pandemic caused by SARS-CoV-2 is a global emergency present in 6 continents including 66 countries, incurring a shortage of effective and safe therapeutic alternatives that can contribute to reducing the risk of contamination, as well as helping to reduce the viral load of the positive patient. This requires a coordinated, effective and immediate action on the part of governments, companies, academic entities and even at the individual level. In the search for new therapeutic and prevention alternatives, the application of hypochlorous acid (HClO) to the nasal mucosa is proposed, a broad-spectrum and fast-acting antimicrobial solution, whose safety has been proven in preclinical trials. The efficacy of HClO has been tested against enveloped and non-enveloped viruses, reducing virus particles without affecting human cells. This solution could contribute to reducing the viral load and the risk of contamination of patients and professionals. This could have an impact on controlling the COVID-19 pandemic.

Infection Tracking in Travellers. The Project Aims to Identify Profiles of Travel-associated Illness and to Follow up on Long-term Sequelae of Arboviral Infections and Malaria

The investigators hypothesize that sex, age, area of exposure and purpose of travel are associated with different travel-related infections. The investigators also hypothesize that certain infections will have long-term sequelae. Health-data will be collected from travellers from Switzerland and Europe. The project starts with a pilot study for 50 travellers, followed by the recruiting of 10,000 travellers. The data collection will be via a mobile App (ITIT). The ITIT App will collect active data from travellers. The participants will download the App after signing an electronic consent form and completing a baseline questionnaire. Then the travellers will answer a short daily questionnaire about illness symptoms during travel. The ITIT App will also collect passive data (GPS localisation, environmental and weather data). The project will provide real-time data on travel-related infections and profile travel illness by age, sex and purpose of travel and also identify outbreaks.
