Filter by:The study proposes to test photodisinfection (PDF) on SARS-CoV-2 in the nose. The study will use Health Canada approved Steriwave™ Nasal Decolonization (ND) in he nostril of patients infected with SARS-CoV-2. Participants are swabbed for SARS-CoV-2 before and after the PDF treatment. For the study, a small group of healthcare workers who have tested positive for SARS-CoV-2 will be included. They will not undergo the treatment but will need to swab their noses multiple times over the next 5 days. This nil group will provide the effect (if any) of swabbing SARS-CoV-2 levels in the nose.
There is an immediate need for population-level intervention research to address the impacts of the coronavirus disease 2019 (COVID-19) pandemic and its containment measures on mental health and substance use (MHSU). While online programs are available to address these issues, they are often delivered in an asynchronous format with relatively low therapist or health coaching guidance. As highlighted by a recent systematic review, positive outcomes for online mental health programs are tied to the intensity of therapist or coaching guidance, which increases cost and reduces population access to more effective online options. A way to offset cost while maintaining effectiveness is to offer MHSU programs to groups online, rather than individually. In 2019, the investigators launched an RCT to test gender-stratified group interventions to address MHSU among community-based Indigenous and non-Indigenous adults in southern Alberta. The investigators implemented the interventions with more than 200 adults before the study was paused due to COVID-19.
Examination of the prevalence of thrombosis in COVID-patients, especially in an out-patient setting. Assessment by duplex sonography. If thrombosis is detected, we will correlate it with immunity status. Assessment of health issues and cognitive function as late complication after infection.
Children are relatively spared from the direct clinical impact of COVID-19. Pediatric patients with regular follow-up at tertiary pediatric centres and presenting one or more chronic conditions might be at increased risk for severe COVID-19. With a prospective seroprevalence study, we aim to study COVID-19 incidence, disease course and risk factors associated with SARS-CoV-2 infection in this specific context.
The study will evaluate the efficacy of Ad26.COV2.S in the prevention of molecularly confirmed moderate to severe/critical coronavirus disease-2019 (COVID-19), as compared to placebo, in SARS-CoV-2 seronegative adults in the double-blind phase and to describe COVID-19 outcomes, safety, and immunogenicity in the different study cohorts in open-label phase.
In the context of the actual pandemia of the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which requires a better diagnostic strategy for the management of patients. The study of volatile organic compounds (VOC) detected in exhaled air or in sweat, is an innovative research area for respiratory diseases. The analysis of VOC can be done either by the technique of the mass spectrometry which allows the identification of each VOC in the exhaled air or by the technique of electronic nose, simpler and faster, which provides an idea of the general profile of the VOC without identifying them. The VOC have shown their interest in some situations, such as diagnostic or prognostic tool in patients followed for thoracic tumorous pathology or bronchial or pulmonary vascular diseases. Moreover, it has recently been shown that properly trained dogs would be able to detect an olfactory signature of SARS-CoV-2 infection with a specificity greater than 90%; this olfactory signature corresponds to VOCs detectable by the flair of dogs (Nosaïs-Covid19 study). Validation of the diagnostic value of VOC analyzes by non-invasive and rapid methods (electronic nose analysis or mass spectrometry; detection by the scent of dogs) for the rapid detection and early diagnosis of a SARS-CoV-2 infection warrants the performance of this clinical study.
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.
The aim of the research is to study the immune checkpoint linked to the HLA-G molecule in the dysregulation of the control of COVID-19 infection.
The benefit of the research is to provide information regarding the efficacy and safety of Favipiravir plus the Standard of Care (SoC) for mild-moderate COVID-19 patients to be a reference for policy recommendations regarding the use of Favipiravir as an antiviral drug for the treatment of Covid-19.
This study will be conducted on eighty patients of both sexes with age ranging from 35 to 45years. The will be recovered from COVID-19 infection with chest symptoms. They will be selected from Nasr city police authority hospital. They will be randomly assigned into 3 equal groups.
