Filter by:An estimated 22% of the global population is at an increased risk of a severe form of COVID-19, while one in four coronavirus patients admitted to intensive care unit will develop a pulmonary embolism. A major public health question remains to be investigated: why COVID-19 is mild for some, critically severe for others and why only a percentage of COVID-19 patients develop thrombosis, despite the disease's proven hypercoagulable state? Patients' intrinsic characteristics might be responsible for the deep variety of disease forms. Our study aims to assess the validity of the hypothesis according to which underlining genetic variations might be responsible for different degrees of severity and thrombotic events risks in the novel coronavirus disease. Moreover, we suspect that prothrombotic genotypes occuring in the genes that encode angiotensin-converting enzyme (ACE-DEL/INS) and angiotensinogen (AGT M235T) are involved in the unpredictable evolution of COVID-19, both in terms of severity and thrombotic events, due to the strong interactions of SARS-CoV-2 with the renin-angiotensin-aldosterone system (RAAS). Therefore, we also aim to assess the validity of the theory according to which there is a pre-existing atypical modulation of RAAS in COVID-19 patients that develop severe forms and/or thrombosis. Our hypothesis is based on various observations. Firstly, there is a substantial similarity with a reasonably related condition such as sepsis, for which there is a validated theory stating that thrombophilic mutations affect patients' clinical response. Secondly, racial and ethnic genetic differences are responsible for significant dissimilar thrombotic risks among various nations. Thirdly, an increase in stroke incidence has been reported in young patients with COVID-19, without essential thrombosis risk factors, favoring the idea that a genetic predisposition could contribute to increase the thrombotic and thromboembolic risk. Fourthly, the plasminogen activator inhibitor (PAI)-1 4G/5G inherited mutation was found to be responsible for a thrombotic state causing post-SARS osteonecrosis.
A prospective, randomized, placebo-controlled, double-blinded, phase III clinical trial of the therapeutic use of convalescent plasma in the treatment of patients with moderate to severe COVID-19
Viral respiratory infections are common infectious complications after kidney transplantation, especially in the pediatric age group, and immunosuppressed patients may develop more severe disease. Immunosuppressive medications alter the patient's immune response by acting on humoral, cellular immunity and neutrophil function, increasing the risk of serious viral infections. Little is known about how these patients respond to infection by the new coronavirus (SARS-CoV-2). Experience with SARS caused by the Influenza H1N1 virus suggests that the severity of the disease depends on pre-existing comorbidities and the individual immune response. In more severe cases, an imbalance between the inflammatory system and the immune system is observed, determining direct consequences when pro and anti-inflammatory cytokines reach the systemic circulation in an exacerbated and unbalanced manner. Such fact can generate "cytokine storm syndrome", resulting in multiple organ dysfunction syndrome. March 2020 reports from Papa Giovanni XXIII Hospital in Bergamo, Italy - one of the largest pediatric liver transplant centers - showed that the number of transplant patients infected with Coronavirus disease 2019 (COVID- 19) increased progressively. However, they did not see greater severity and complications in this population. Immunosuppression could act as a protective factor. The present study aims to describe the prevalence of viral infection by SARS-CoV-2 in a sample of immunosuppressed children, from three groups: kidney transplants, liver transplants and oncohematological. The investigators will also look for the epidemiological profile and clinical evolution of these patients, enabling a better understanding of the COVID-19 in this special population. The investigators' hypothesis is that infection with the new coronavirus may be asymptomatic in a large number of children and that immunosuppression, observed in liver and kidney transplant patients and also seen in cancer patients, may act as protection for severe forms of COVID-19. After obtaining written informed consent from the family, the investigators will include patients from 0-18 years of age, on regular outpatient follow-up, symptomatic or not, and will check for the presence of IgM/IgG antibodies against the SARS-CoV-2. For those symptomatic or with a positive IgM result, material (oro/nasopharyngeal swabs) for RT-PCR trial for the new coronavirus will be collected. Demographic and clinical variables will be registered. The outcomes are: Serology for COVID-19 result; PCR for COVID-19 result; presence of symptoms of COVID-19; proportion of patients with viral shedding on days 3,7,14,21 and 30 after diagnosis; need for hospital admission; need for Intensive care admission; death.
The coronavirus (COVID-19) pandemic continues to grow exponentially. Angiotensin II levels are increased in human influenza and are associated with influenza viral load, disease progression and mortality. Preliminary data shows angiotensin II receptor blockers (ARBs) limits lung injury in murine influenza H7N9, as well as viral titre and RNA. ARBs could limit viral titre and organ injury in COVID-19. We will therefore collect clinical chart data and test angiotensin II levels of patients who are admitted to ICU with COVID-19 to determine whether there is a correlation between taking ARBs and clinical outcomes in these patients. Other blood biomarkers and clinical risk factors for COVID-19 have come to light in recent weeks. We include these in our observational analysis to help generate an understanding of COVID-19 presentation and blood biomarker characterization of disease.
Coronavirus Disease 2019 (COVID-19) has been widespread worldwide since December 2019. It is highly contagious, and severe cases can lead to acute respiratory distress or multiple organ failure. On 11 March 2020, the WHO made the assessment that COVID-19 can be characterised as a pandemic. With the development of machine learning, deep learning based artificial intelligence (AI) technology has demonstrated tremendous success in the field of medical data analysis due to its capacity of extracting rich features from imaging and complex clinical datasets. In this study, we aim to use clinical data collected as part of routine clinical care (heart tracings, X-rays and CT scans) to train artificial intelligence and machine learning algorithms, to accurately predict the course of disease in patients with Covid-19 infection, using these datasets.
The C-MORE study is prospective observational holistic longitudinal study which will characterise the prevalence of multi-organ injury among COVID-19 survivors post hospital discharge and assess its effects on quality of life, exercise tolerance and mental health.
The McMaster Multi-Regional Hospital Coronavirus Registry (COREG) is a platform that is collecting detailed case data on laboratory confirmed COVID-19 hospital inpatients and outpatients. The COREG platform will provide rapid high-quality evidence to improve the prevention and clinical management of COVID-19 for older adults in Canada, and internationally. The COREG platform will also provide researchers and partners with complete regional level clinical data on COVID-19 cases to inform rapid decision-making and projections, sub-studies, extensions, and linkage for all affected populations.
In December 2019, a highly infectious disease caused by a novel coronavirus (SARS-CoV-2) emerged in Wuhan, China. On March 11th 2020, the World Health Organization (WHO) declared COVID-19 a pandemic. Facing this critical situation, health care workers on the front line are at risk of developing psychological distress and other mental health symptoms. Physical medicine and rehabilitation (PM&R) physicians works both in specialty outpateint/inpatient clinic and pandemic outpatient/inpatient clinics during the outbreak. Accordingly, PM&R physicians are expected to be mentally affected by COVID-19 pandemic. In this study we aimed to evaluate mental health status of PM&R physicians and related factors during COVID-19 pandemic. This study is a cross-sectional survey which is conducted on an online platform. Demographic data, working conditions of PM&R physicians and factors that may be related to mental health status is questioned in the survey. The Depression, Anxiety and Stress Scale - 21 (DASS-21) is used to measure the emotional states of depression, anxiety and stress.The Insomnia Severity Index (ISI) is used to assess the severity of both nighttime and daytime components of insomnia.
The coronavirus outbreak has adversely affected individuals in the community, as in the rest of the world. However, in order to carry out this epidemic period in a healthy and conscious manner, determining the anxiety levels of individuals in the society and supporting them psychologically is of great importance. In order to achieve this, healthcare professionals working clinically or academically have important duties. This study was planned to test its validity and reliability in order to adapt the Coronavirus Anxiety Scale to Turkish.
The cytokine storms mediated by over production of proinflammatory cytokines have been observed in a large population of critically ill patients infected with COVID-19. Patients diagnosed with cytokine storms progress to cardiovascular collapse, multiple organ dysfunction and death rapidly. Therefore, early identification, treatment and prevention of the cytokine storms are of crucial importance for the patients. Immuomedulator such as interleukin-6 (IL-6) antagonist, emerged as an alternative treatment for COVID-19 patients with a risk of cytokine storms recently. In this study, we aimed to evaluate the safety and efficacy of anti-IL6 alone vs anti-IL6 corticosteroid combination in patients with COVID-19 pneumonia
