Filter by:This is an exploratory study to evaluate the efficacy of Doxycycline (200mg on D1 to D7) and Rivaroxaban (15 mg daily on D1 to D7) versus the combination of Hydroxychloroquine (400 mg on D1 to D7) and Azithromycin (500 mg on D1 and 250mg on D2 to D5) as per national standard to treat ambulatory mild COVID-19 patients, with the aim to achieve early negativity of RT-PCR of SARS-CoV-2 from nasopharyngeal swab, and early clinical improvement and prevention of severe disease.
Objective: To determine whether NIV delivered through helmet interface reduces intubation rate among patients with COVID-19 ARDS compared to face-mask NIV and HFNC. Design, setting & participants: Two-center randomized clinical trial of 360 patients with mild to moderate ARDS and confirmed COVID-19 requiring non-invasive ventilation between August 2020 to January 2021. The patients with respiratory rate (RR) more than 30/min or oxygen saturation (SpO2) less than 90% or PaO2/FiO2 ratio less than 300 despite standard oxygen therapy by face mask (<15 L/min) who present to Royal hospital or Sultan Qaboos University Hospital (SQUH) emergency department, medical wards or intensive care unit (ICU). Intervention: Patients will be randomly assigned (block randomization) to either face-mask NIV, HFNC or Helmet NIV. The helmet is a transparent hood that covers the entire head of the patient and has a rubber collar neck seal. Main outcome and measures: The primary outcome is the rate of endotracheal intubation at 28-days. Secondary outcomes include hospital mortality at 28 and 90 days, NIV free days, invasive ventilator free days and hospital length of stay. Expected results: We assume the failure rate of Helmet NIV to be 30%, failure rate of HFNC to be 40% and failure rate of face-mask NIV to be 50%. A sample size of 360 patients (120/group) will achieve a power of 0.90 at a significance level of 0.05. To account for 10% dropout rate, the total sample required is 396 subjects(132/group).
The current study aimed to make a therapeutic comparison and effectiveness of Hydroxychloroquine (HCQ) and Montelukast (ML) in COVID-19 patients in addition to the standard of care. The safety and efficacy of HCQ and ML will be assessed as individual therapy and in combination with each other and with the standard of care. Cytokine storm (Interleukin levels) also will be monitored throughout the study to assess treatment progression.
Our primary aim is to collect breath samples from COVID-19 positive patients at the time of diagnosis, during and after recovery using the same patient as his/her own control to identify VOCs specific to SARS-COV-2 viral infection. A secondary aim is to determine the patient's likely disease trajectory in terms of recovery versus progression to respiratory and or multi-organ failure. Breath samples will be collected as soon as the patient is admitted to the Vancouver General Hospital COVID Ward with a diagnosis of COVID-19 by RT-PCR in nasopharyngeal/throat swab. A second breath sample will be obtained one week later, or before hospital discharge or if they become sicker prior to transfer to the intensive care. A third sample will be taken to 8-12 weeks after recovery from the illness with a negative COVID-19 RT-PCR test. VOCs in exhaled breath will be measured by gas chromatography-mass spectrometry (GC-TOF-MS or GCxGC-TOFMS). VOC profiles from the symptomatic phase and recovery phase will be compared to determine if there are unique VOCs associated with COVID-19 infection. Comparison of VOC profiles between those who recover and those who progressed will provide information on potential prognostic features. The results of this pilot study will form the basis to determine if a larger study is warranted.
Around 90.000 patients have been hospitalised due to COVID-19 infection in France between March 1st and June 15th; 19% of those requiring intensive care. Approximately 80% of these patients have been discharged home by September 30th. Nonetheless, COVID-19 infection along with intensive care consequences are very likely to impede those patients quality of life and functional capacities. This study aims to describe the quality of life outcomes and functional capacities of COVID-19 survivors, at least 6 months after primary care hospital discharge.
This study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.
The coronavirus disease 2019 (COVID-19) pandemic represents a major threat to global health. Since the beginning of the COVID-19 epidemic, all eyes have been focused on the significant somatic complications of COVID-19, but the impact on behaviors, particularly those that can lead to addictive disorders, remains little studied. A set of factors could explain a change in gambling activities, both in number of gamblers and in intensity of practices, due to the pandemic. On the one hand, the reduction or even the interruption of sporting and horse racing competitions may induce a decrease in these activities (both online and offline). Moreover, the closure of certain gambling venues and travel restrictions may also lead to a decrease of offline gambling activities in general. On the other hand, gamblers who can no longer perform their usual gambling activity could refer to available online gambling activities (poker, lotteries, casinos, etc.). Moreover, the threat of a financial crisis, the negative impact on psychological well-being (due to social isolation, stress of being infected, etc.), and increased time spent freely online, could also very largely motivate an initiation or an exacerbation of the gambling activity, especially online and in people in a situation of vulnerability. Both in France and Sweden, the closing of sports and horse race events has led to a sharp decrease in sports and horse-race betting. In both countries, the increase in other gambling types, including illegal gambling, and their potential for gambling problems is a source of concerns for public health authorities. As a consequence, more research is promptly needed in this area. The use of gambling tracking data, widely acclaimed in recent years in research on online gambling given its ecological nature, could allow observing longitudinally changes in online gambling practices (both the raw gambling activity and risky behaviors) and in the use of responsible gambling (RG) tools due to the pandemic. Moreover, the combination of French and Swedish data will allow comparing two countries with very distinct politics regarding the pandemics, i.e. a lockdown in France in March - May 2020 and then in November - December 2020 compared to no lockdown in Sweden. Finally, gambling in women is on the rise and women display specific gambling behaviors, especially in early stages of the online gambling practice. The project will include the investigation of gender specificities both in the investigation of the impacts of the pandemic and in the comparison of French and Sweden gambling behaviors. Age, type of gambling activity and country (France / Sweden) will also be taken into account.
Due to the cytokine storm that develops as a result of Coronavirus Disease 2019 (COVID-19) infection, some patients hospitalization to intensive care cause of pneumonia, Acute Respiratory Distress Syndrome (ARDS) and multiple organ failure. Mortality is higher in treatment-resistant cases. Purpose of this study: 1. Providing immune modulation by Stem Cell Transplantation and reducing the damage caused by cytokine storm to tissues and organs, 2. Correcting immunosuppression and fight against COVID-19 virus by editing B and T cells, 3. It is to accelerate healing in organ damage by increasing growth factors through mesenchymal stem cells. Primary outcome: Improvement of clinical symptoms, reduction of cytokine storm Secondary outcome: Recovery of patients; from mechanical ventilation
The aim of this study is to evaluate the predictive value for in-hospital mortality of respectively the SOFA and Apache scores in a COVID-19 ICU cohort and to develop a new prediction model for COVID-19 patients admitted to the ICU from 13th of March 2020 until 17th of October 2020.
