Filter by:Since December 2019, the outbreak of coronavirus disease 2019 (COVID-19) has become a public health emergency of international concern. Although corticosteroid therapy represents a milestone in the management of COVID-19, many questions remain unanswered. The optimal type of corticosteroids, timing of initiation, dose, mode of administration, duration, and dose tapering are still unclear. An approach to resolve these issues is to develop accurate tools to assess or monitor the progression of COVID-19 during the corticosteroid therapy process. Quantitative computed tomography (QCT) analysis may serve as a tool for assessing the severity of COVID-19 and for monitoring its progress. However, the effect of steroids on quantitative chest CT parameters during the treatment process remains unknown. In this retrospectively study, we aimed to assess the association between steroid administration and QCT variables in a longitudinal cohort with COVID-19
The study is a prospective, pilot study aimed to test the safety of Tumor Treating Fields (TTFields) concomitant with best standard of care, for the treatment of hospitalized COVID-19 patients and continued treatment after hospitalization. The device is an experimental, portable, battery operated device for chronic administration of alternating electric fields (termed TTFields) to the region of the organ to be treated, by means of surface, insulated electrode arrays.
The current study primarily aims to determine the status of vaccination in enrolled cancer patients and identify barriers to coronavirus disease 2019 (COVID-19) vaccination in cancer patients who have not been vaccinated. Secondary objectives include determining the rate of vaccination in those who have ever been COVID-19 positive and those who have never been COVID-19 positive. The study team also seeks to determine factors associated with vaccine-acceptance and vaccine-hesitancy in the adult cancer population, identify side effects of COVID-19 vaccines in vaccinated cancer patients and to examine the effect of COVID-19 vaccination on overall clinical outcome in cancer patients. The study team will be conducting telephone interviews/surveys with up to130 adult cancer patients for data collection.
The COVID-19 pandemic has led to an increase in the number of patients admitted to intensive care units (ICU) with acute respiratory distress syndrome (ARDS). ARDS is a severe, life-threatening medical condition characterised by inflammation and fluid in the lungs. There is no proven therapy to reduce fluid leak, also known as pulmonary oedema, in ARDS. However, recent studies have discovered that imatinib prevents fluid leak in the lungs in inflammatory conditions, while leaving the immune response intact. Adding imatinib into the standard care package may, therefore, decrease mortality and reduce the duration of mechanical ventilation compared with standard care alone, in critically-ill patients with COVID-19. To help determine the impact of imatinib in these patients we present a randomised, double-blind, multi-centre, 2-arm, parallel-group, placebo-controlled clinical study of intravenous imatinib in 84 mechanically-ventilated, adult subjects with COVID-19-related ARDS. Study participants (patients who have consented into the study) will receive the study drug (imatinib or placebo) twice daily for a period of 10 days. The effect of the intervention will be tested by measuring the change from baseline in the Oxygen Saturation Index (OSI) at day 10. OSI is a non-invasive means of measuring oxygenation and is an independent predictor of mortality in patients with ARDS, serving thus as a relevant endpoint from which to assess the efficacy of imatinib. Other measurements will include regular blood tests as part of safety assessments. Time on ventilation and morbidity and mortality will be recorded as secondary outcome measures. Blood tests will also allow the investigation of the pharmacokinetic properties of imatinib, as well as biomarkers of inflammation.
Aim of the study is to evaluate the presence of SARS-CoV2 RNA in the saliva of patients with suspected or confirmed COVID-19 in order to validate the analysis of this type of sample for the diagnosis of SARS-CoV2 infections.
COVID-19 caused by SARS-CoV-2 virus has affected the lives of millions of individuals globally and also severely strained the medical community. Pre-symptomatic and asymptomatic SARS-CoV-2 positive individuals far outnumber the symptomatic ones or those with severe disease. The transmission potential of SARS CoV-2 is potentially greater than earlier viral outbreaks of SARS-CoV and MERS-CoV.Routine measures of social distancing, personal hand hygiene and limited outdoor contact activities have shown benefits to limit corona virus infection. However, the role of vitamin D in SARS-CoV-2 infection is sparingly explored despite the knowledge of an immunomodulatory role and protective effect of vitamin D against viral infections. Meta-analysis of five clinical trials of vitamin D supplementation found that those receiving vitamin D supplementation had fewer respiratory tract infections (odds ratio = 0.58 (95%CI, 0.42 - 0.81).Any immune-modulatory effect of vitamin D is likely to be observed at levels which are considered higher than that required for normal bone metabolism.
Acute respiratory distress syndrome survivors frequently develop impaired physical function, muscle weakness and quality of life. The aim of this retrospective study is to determine the functional capacity, global muscle weakness and quality of life of COVID-19 survivors after 4 weeks following hospital discharge and the relationship between different tools. COVID-19 related acute respiratory distress syndrome survivors were assessed 4 weeks following discharge from the hospital, 15 patients who attended the evaluation will be included the study. All subjects underwent standardized physical clinical evaluation, Medical Research Council-sumscore, hand-grip strength, 6-minute walk test, chair-stand test, timed up and go test and Short form-36, 4 weeks after hospital discharge.
MAD0004J08, the experimental drug, is a potent neutralizing IgG1 monoclonal antibody (mAb) targeting the spike protein of SARS-CoV-2. MAD0004J08 blocks viral attachment and entry into human cells and neutralizes the virus. Because of its high affinity and potency, MAD0004J08 may accelerate clearance of the virus and prevent clinical deterioration of COVID-19 patients, especially when administered shortly after infection, and prevent SARS-CoV-2 infection in uninfected subjects. Because of its high potency, MAD0004J08 is expected to be effective at low doses (mg range) and thus will be administered by intramuscular (IM) injection, as opposed to the intravenous bolus required by high dose mAbs. The goals of this Phase II-III seamless adaptive clinical trial are: Stage-1 (Phase II) 1. Select one dose level for progression to Stage-2 Stage-1 + Stage-2 (Phase III) 2. Provide confirmatory evidence of safety and efficacy for regulatory approval.
This is a randomized, observer-blind, parallel-controlled study, for evaluation of safety and immunogenicity of sequential immunization of a recombinant COVID-19 vaccine (adenovirus type 5 vector) in Chinese healthy adults aged 60 and above after the priming vaccination of inactivated vaccine. 300 healthy subjects aged 60 and above will be recruited in this study. Of them, 200 subjects who have been vaccinated with two dose of inactive SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 3~6 months later. Other 100 subjects who have been vaccinated with one dose of inactivated SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 1~3 months later. The occurrence of adverse events within 28 days and serious adverse events within 6 months after vaccination will be observed. In addition, blood samples will be collected on day 0 before the boosting with ad5 vectored vaccine and on day 14, 28 and month 6 after the boosting. Serum antibody levels, cellular immune responses and the subgroups or germlines of the specific B cells will be analyzed. Each subject will remain in this study for approximately 6 months.
Despite large-scale, nationwide efforts to better address suicidal behavior in Veterans at high risk, the development of interventions that target some of the key risk factors associated with suicide remains limited. This study aims to collect pilot data to test feasibility/acceptability of a novel adjunctive evidence-based cognitive remediation (CR) therapy with manualized "Bridging" sessions for transfer and practice of problem-solving strategies for real-world stressors, including those that trigger suicidal thoughts. This 10-week (20 session) Neuropsychological Educational Approach to Cognitive Remediation CR+Bridging telehealth intervention will be administered virtually via HIPPA-compliant services to 36 Veterans with major depressive disorder and a history of suicide attempt(s). Pre-, post-treatment, and follow-up assessments of neurocognitive, clinical, social, and real-world functioning also will be conducted. This study has potential for high public health impact and promise to help improve quality of life for Veterans at high risk for suicide.
