Active clinical trials for "COVID-19"

A frequent complication of COVID-19 disease is pulmonary embolism (PE). Lung ventilation/perfusion (V/P) scintigraphy is a well-established test for PE diagnosis. The test is interpreted based on the recognition of wedge shaped perfusion mismatched defects. However, the ventilation procedure increases the potential risk of contamination by the aerosol secretion and the expired air. A variety of strategies have been proposed in the nuclear medicine literature regarding performance of lung ventilation scintigraphy in COVID-19 patients with suspected acute PE. However, there is currently no factual data in this specific population to support recommendations to the nuclear medicine community. The aim of this study was to assess the role of ventilation imaging when performing lung scintigraphy for suspected PE in COVID-19 patients.

To determine the accuracy of Proof Diagnostics COVID-19 Test in the intended, symptomatic and suspected/at-risk asymptomatic population and point-of-care use as compared to a standard molecular comparator, Quidel Lyra SARS-CoV-2 Assay for diagnosing SARS-CoV-2 infection.

It is important to evaluate the vaccine-related metabolic changes on FDG PET/CT to avoid confusing results. The investigators aimed to assess the frequency and intensity of regional and systemic metabolic PET/CT changes of patients who received the mRNA-based COVID-19 vaccine (BNT162b2-Pfizer/BioNTech) and to analyze possible factors affecting these changes.

The purpose of the study COVID-EP is to classify all the complications occurring after the diagnosis of pulmonary embolism in patients tested initially COVID-19 positive and negative by RT-PCR (on nasopharyngeal sample) during the peak of the pandemic in France (April 2020). The patients will be followed for 1 year in order to provide clinical and paraclinical data not yet published in the literature. In order to secondarily confirm the COVID-19 status of initially negative COVID-19 patients (by RT-PCR), a serology test will be performed. The collected complications will then be compared between each of the 3 following groups: [PCR-COVID 19-Neg & Sero-COVID 19-Neg] versus [PCR-COVID 19-Neg & Sero-COVID 19-Pos] versus [PCR-COVID 19-Pos].

This study is an observational study (Non-interventional study) to evaluate the safety and efficacy of favipiravir in patients older than 15 years of age, diagnosed with COVID-19 and initiated treatment with favipiravir before enrollment to the study. Patients who have already had a routine favipiravir treatment decision or alternatively favipiravir treatment started at the time of enrollment, will be included in this study.

SAR-Cov-2 infection and its clinical manifestation known as COVID-19 beside the respiratory and lung involvement may include the cardiovascular system, the nervous system and the liver. In the acute phase of the disease, all of these conditions may be life-threatened. As a result, after the acute phase of COVID-19, early complications may be observed, including heart, lungs, brain, muscles and liver. A few papers to date have been reported of myocarditis, ventricular arrhythmias, post-inflammatory changes in the lung and liver, as well as ischemic changes in the brain, diseases of skeletal muscle, which may have adverse prognostic effects. Due to the extent of the pandemic, the severity of the complications and the expected high complications' prevalence in the early post-recovery period, a study was designed to determine the extent of the problem of early complications after COVID-19. Complex cardiological, pulmonary, neurological and hepatological diagnostics are planned, including laboratory, imaging and functional tests. The results obtained, in addition to determining the scale of the problem, will allow the selection of studies that optimally identify patients with early complications. The purpose of this procedure is to enable rapid treatment of diseases that are complications of SARS-COV-2 infection. An additional aspect raised in the project will be the issue of psychiatric disorders (anxiety, depression, post traumatic disorders). The main three purposes of the study include: the assessment of prevalence of particular complications after COVID-19. identification of the demographic and clinical risk factors of COVID-19 complications determining the diagnostic tests which are sufficient to detect early complications of COVID-19

1. Objectives: 1.-To create risk stratification scales of poor evolution in patients infected by SARS-CoV-2. 2.-Evaluate the accessibility and equity that these patients have had in the different care processes, diagnostic and therapeutic procedures, with special interest in patients who came from residences, by age, gender or geographic origin.3.-Evaluate the effectiveness of different therapeutic schemes that have been used in this pandemic. 4.-Evaluate the effectiveness of different diagnostic tests used to predict the poor evolution of these patients 5.- Evaluate the real costs associated with the treatment of hospitalized patients with COVID-19 ; 2. Methods: Information will be recorded from electronic medical record: epidemiological data, onset of symptoms, comorbidities and their treatments, symptoms, analytical data, vital signs, tests performed, treatments during admission and evolution up to 3 months after discharge. Statistical analysis: The investigators will use classic survival models, logistic regression, generalized linear models and also analysis using artificial intelligence techniques . Health care costs are assessed. Applications for decision making will be derived as a product.

The recent COVID-19 outbreak has put the health care workers on the frontline to interact and provide support to the patients. Based on previous disease outbreak-associated studies, it is evident that these individuals are at a high-risk of developing psychological distress such as burnout, anxiety, depression, and stress (BADS). Thus, the current study aims to evaluate the mental health outcomes of healthcare workers dealing with COVID-19 patients within Qatar and internationally, during and after the COVID-19 crisis. The participants will be divided into two groups: those working with COVID-19 patients and those not working with COVID-19 patients. The magnitude of symptoms of BADS will be assessed using electronic versions of the standardized questionnaires: Maslach Burnout Inventory (MBI-HSS), Hospital Anxiety and Depression Scale (HADS), Depression, Anxiety and Stress Scale (DASS-21), and Conditions for Work Effectiveness (CWEQ). A follow-up survey will be sent to both groups after the COVID-19 crisis to assess their vulnerability to develop post-trauma stress disorder (PTSD) using a PDS-5 survey.

The purpose of this study is to assess the potential for a non-invasive sensory based intervention to reduce the stress associated with a COVID-19 diagnosis.

Studies have shown that admission to hospital during a coronavirus epidemic is associated with increased levels of anxiety, depression and panic disorder. During the SARS-CoV-2 pandemic in North London the Royal Free Hospital admitted over 500 patients with Covid-19. As part of the standard of care, these patients are screened at 8 weeks post discharge for signs of anxiety and depression. The Feeling Good app is a NHS approved digital application which utilises applied relaxation, mindfulness based cognitive therapy and positive visualisation through audio tracks for the treatment of anxiety and depression. This is a naturalistic cohort study aimed to track the post illness psychological symptoms of those who have been admitted with Covid-19 to the Royal Free hospital up to 5-7 months after discharge. The study population is those who are exhibiting anxiety or depressive symptoms as measure by the PHQ-2 or TSQ questionnaires. All those with symptoms will be offered free access to a NHS approved app for anxiety and depression, and followed up for 3 months after recruitment to track changes to their symptoms.
