Filter by:The United Kingdom and wider world is in the midst of the 2019 novel coronavirus (SARS-CoV-2) pandemic. Accurate diagnosis of infection, identification of immunity and monitoring the clinical progression of infection are of paramount importance to our response. Widespread population testing has proven difficult in western countries and has been limited by test availability, human resources and long turnaround times (up to 72 hours). This has limited our ability to control the spread of infection and to develop effective clinical pathways to enable early social isolation of infected patients and early treatment for those most at risk. The life sciences industry has responded to the pandemic by developing multiple new in vitro diagnostic tests (IVDs). To leverage the potential clinical benefit of those tests we require efficient but robust clinical evaluation. Therefore, to optimise resource utilisation in this global pandemic, we will conduct a platform adaptive diagnostic study on a national level, utilising a national network of expertise in the evaluation of diagnostic technology. This study will enable the evaluation of multiple assays in three priority areas: 1. Evaluation of the diagnostic accuracy of IVDs for active infection with SARS-CoV-2 2. Evaluation of assays monitoring the immune response to SARS-CoV-2 infection 3. Evaluation of the prognostic value of commercially available tests for predicting prognosis in patients with suspected or confirmed SARS-CoV-2 infection. (This arm will not be active immediately but may be activated after initiation).
Background The immediate psychological impact of COVID-19 is already emerging. The investigators are interested in the benefits of a self-management booklet focused on the current circumstances in response to the COVID-19 pandemic on people's physical and mental wellbeing. Who can participate? The investigators are looking for participants aged 18 and over who live in the UK and can read and write in English, without any current serious mental health problems (e.g. bipolar disorder, PTSD, active thoughts of self-harm, or severe anxiety/depression), and who feel that their physical and/or mental wellbeing have been affected since the COVID-19 pandemic. What does the study involve? Eligible participants will complete questionnaires at baseline following which they will be randomly allocated to either receive the self-management booklet right away (via email) or after 4 months (waiting-list, in the meantime participants will be provided a link to educational materials). Participants will not be able to choose whether they will receive the self-management booklet right away or be in the waiting-list as a computer system (Qualtrics randomiser) will allocate them to one of the two groups at random. Participants in both conditions will be asked to complete online questionnaires at multiple time points, 2-months and 4-months after allocation. Participants in the waiting-list condition will also be asked to complete the same set of questionnaires at 6- and 8-months after allocation to assess how beneficial they found the self-management booklet. Participants will also be invited to take part in an audio-recorded interview after T2 to tell us more about how they found the self-management booklet or the educational materials. The investigators will select 30 participants (15 from each condition) for the interview out of those who opt-in to capture a wide range of experiences and backgrounds. What are the possible benefits and risks of participating? Risks to participants are small. Participants may find reflecting on the impact of COVID-19 on their lives distressing. However, these effects are anticipated to be short lived, as participants will learn psychological techniques during the intervention that can help them manage better in the current circumstances and improve their wellbeing. Where is the study run from? The lead site is King's College London. The study is run online via Qualtrics. When is the study starting and how long is it expected to run for? May 2020 to May 2021 Who is the main contact? Dr Federica Picariello federica.picariello@kcl.ac.uk
Collection of nasal/nasopharyngeal/throat swabs and blood samples from patients presenting at their designated care facility displaying symptoms of COVID-19 and undergoing a SOC SARS-CoV-2 test or those who have tested positive in the past to aid development, calibration and performance evaluation for the LumiraDx POC test.
The plan is to transfuse COVID-19 infected patients with convalescent plasma and observe whether this will result in a significant improvement in clinical outcome in comparison to historical experience.
Coronavirus disease 2019 (COVID-19) and associated emergency measures (EM) have dramatically impacted the lives of children/adolescents (children) and families. The closure of schools, social and recreational activities, and modifications to work environments has led to significant changes in the way children and families are working, living and socializing. Although the impact on the mental health of children and families has not been well researched, it is anticipated that already stressed children and families with pre-COVID-19 mental health challenges are at significant risk for deterioration in their mental health. As such, the implementation, and evaluation (specifically: feasibility, acceptability and barriers) of virtual-care interventions to alleviate child and family anxiety and enhance family functioning are critical. Virtual-care also optimizes health equity initiatives in reducing social, economic and environmental barriers to services that can improve or maintain mental health (WHO, 2017; MOHLTC, 2018). The current study will evaluate an adapted virtual-care cognitive behavioural therapy (CBT) program for children with anxiety (VC-CBT). CBT has a strong evidence-base in treating children with anxiety disorders (Higa-McMillan, Francis, Rith-Najarian, and Chorpita, 2016; Seligman and Ollendick, 2011), with increasing evidence supporting the efficacy of virtual-care CBT for childhood anxiety disorders (Carpenter, Pincus, Furr, and Comer, 2018; Slone, Reese, and McClellan, 2012). This study aims to evaluate the feasibility, participation barriers related to social determinants of health (SDH) and acceptability of this virtual-care intervention in addressing mental health challenges associated with the COVID-19 pandemic and ensuing EM in the immediate time-period. Early evaluation of this virtual-care intervention will enable future scale-up of this intervention during the post-pandemic recovery time-period and during subsequent COVID-19 waves, if necessary.
Seroepidemiological Study of SARS-CoV-2 Infection in Population Subgroups in the State of São Paulo
The current situation of Sars-Cov-2 pandemic generates fears in the general population. Among patients receiving long-term immunomodulatory drugs, especially in the context of auto-immune diseases, there may be legitimates interrogations about the appropriateness of continuing treatment, without modification, in the current context. Juvenile Idiopathic Arthritis is concerns by these fears (the patient and their parents). Patients are treated by several classes of immunomodulatory drugs, including non-steroidal anti-inflammatory drugs, corticosteroids and disease modifying anti-rheumatic drugs. The present study will characterize this issue by defining the proportion of patients whose usual treatment of Juvenile Idiopathic Arthritis has been modified in relation to the actual sanitary crisis, and also to return to school.
Comparison of the effects of CYT107 vs Placebo administered IM at 10μg/ kg twice a week for two weeks on immune reconstitution of lymphopenic COVID-19 patients.
The Covid-19 viral pandemic has caused significant global losses and disruption to all aspects of society. One of the major difficulties in controlling the spread of this coronavirus has been the delayed and mild (or lack of) presentation of symptoms in infected individuals, and the insufficient Covid-19 testing capacity in the UK. This warrants the development of alternative diagnostic tools that reliably assess Covid-19 infection in the early stages of infection, while also being low- cost, low-burden, and easily administered to a wide proportion of the population. This study aims to validate machine learning models as a diagnostic tool that predicts infection with SARS-CoV-2 based on app-reported symptoms and phenotypic data, against the 'gold-standard' swab PCR-test. This study will take place within the Covid Symptom Study app, the free symptom tracking mobile application launched in March 2020.
