Filter by:Myopericarditis is a rare complication to messenger ribonucleic acid (mRNA) COVID-19 vaccines, especially in male adolescents and young adults. The risk in children 5-11 years old is unknown. In Denmark, the Pfizer-BioNTech mRNA COVID-19 vaccination was recommended from December 1, 2021 in individuals aged 5-11 years old. We aim to estimate the incidence of myopericarditis in children 5-11 years old after mRNA COVID-19 vaccination among vaccinated individuals based on a nationwide prospective population-based cohort study with detailed clinical phenotyping.
The food supplement Endocalyx is considered to support the endothelial glycocalyx integrity by supplying sulfated polysaccharides, anti-oxidant enzymes and additional substrates for glycocalyx synthesis. The investigators will study the effect of Endocalyx on endothelial, vascular and left ventricular myocardial function in patients with COVID-19 infection.
Experimental open-label randomized clinical trial to determine the effect of virtual Cognitive Behavioral Therapy (CBT) on the quality of life of patients with HIV, COVID-19 and anxiety or depression. It will be carried out at the hospital for 6 months, where people over 18 years of age with HIV from the infectious disease service will participate. In the study, patients will be randomized 1:1 in an intervention group, who will receive eight sessions of virtual CBT by 02 psychotherapists, and a control group. Additionally, patients will be consulted about the participation of at least one adult family member or caregiver in the study, if the patient and the family member agree, the family member or caregiver will enter the study. The informed consent process will be conducted by telephone, during the call the recruiting staff will read the consent document and the participant (patient and family member or caregiver) will give their consent by answering affirmatively to the questions asked at the end of the document. The main objective will be evaluated by comparing the quality of life measurement at three months with the baseline measurement, as well as the variation of anxiety and depression scores.
COVID-19 vaccinations are predicted to be a huge success in pandemic control. However, the majority of the studies were conducted on healthy individuals, and the efficiency of COVID-19 vaccination in post-transplant patients is uncertain. In the setting of HSCT, the extreme immunosuppression caused by the conditioning regimen and the graft versus host disease (GvHD) preventive regimen clearly has an impact on the efficacy and immunogenicity of the COVID-19 vaccine. Given the importance of eliciting early SARS-Cov-2 protective immunity in patients who are undergoing Allo-HSCT and the EBMT recommendation to endorse vaccination as early as 3 months after allo-HCT [7], we conduct this prospective study to investigate the safety and immunogenicity of three doses Pastucovac (an RBD-based SARS-Cov-2 vaccine) at the early post-transplant period in adult Iranian patients who are undergoing Allo-HSCT. We also want to see whether there are any possible predictors, such as the effect of clinical characteristics and lymphocyte subpopulations at the time of vaccination on the serologic response following immunization. The findings of this study will serve to guide future COVID-19 vaccination recommendations in this population, such as the optimal starting time, interval time, and so on.
SARS-COV-2 infection can progress to acute respiratory distress syndrome and require hospitalization in the ICU in 5-20% of affected patients. Age is a major risk factor for developing a severe form and for death. ARDS related to SARS-COV-2 has specific features, including the need for long mechanical ventilation and length of stay and the use of corticosteroid therapy. These specificities are responsible for significant morbidity (neuromyopathy, delirium, post-resuscitation syndrome) and mortality during the first wave (46% at 3 months for the population of patients aged 70 years and over). To investigator's knowledge, no study has evaluated the prognosis in the ICU and the long-term functional outcome of elderly people admitted for a severe or critical form of COVID-19 since the major changes in management (dexamethasone, screening for thrombo-embolic complications, use of high-flow oxygen therapy as first-line treatment...). Investigator therefore propose a 1-year follow-up of a cohort of patients aged 70 and over hospitalised in a conventional service or in intensive care for a severe or critical form of COVID-19. The objectives are to describe the prognosis and functional outcome of hospitalized elderly patients with severe COVID-19.
Introduction: Coronavirus disease 2019 (COVID-19) remains a major health issue resulting in >800,000 deaths as of 30th August 2020. A concerning discovery of COVID-19 is the involvement of the myocardium. Several case studies including one from our group (recent study publication in JACC Cardiovascular Imaging led by the principal investigator of this grant application) have demonstrated subclinical myocardial inflammation in patients using cardiac magnetic resonance imaging (CMR) who have recovered from COVID-19. Furthermore at a cellular level, a recent autopsy study indicated that the severe acute respiratory syndrome coronavirus-2 is present in the myocardial tissue. The study further described invasion and viral progeny occurring in the myocardial interstitial cells and as such is a concerning development with the longer-term implications being unknown. These concerns have been noticed by the cardiology and non-cardiology medical community, with some expressing concerns of a new cause for cardiomyopathy and heart failure secondary to COVID-195. Therefore, it is critical that further studies are conducted to determine the longer-term outcome for patients.
COVID-19 associated mortality remains high despite the advances in therapeutics such as dexamethasone. The severity of COVID-19 results from direct viral cytotoxicity, and the inflammatory response, which is associated with a hypercoagulable state, contribute to lethal hypoxemic pneumonia. During the SARS-CoV-2 replication phase, infected cells secrete chemokines and die by activating the immune system locally. A local inflammatory loop induces tissue destruction, which activates the immune system's circulating cells, leading to another amplifying loop called the cytokine storm. In these phenomena, the integrity of the interferon pathway plays a significant role. Specific impairment of the interferon pathway has been identified in a subset of patients and is associated with high Covid-19 severity. This subset of patients presents preexisting autoimmune disease mediated by autoantibodies directed against IFN. It represents 10.2% (101/987) of patients admitted in ICU with COVID-19 pneumonia, and the observed mortality in this subgroup is 40%. The investigators hypothesized that plasma exchanges (PE) would eliminate these autoantibodies while acting on other mechanisms of the pathogenesis of severe COVID-19, such as cytokine storm or hypercoagulability(7). The EPIC trial aims to demonstrate the efficacy of plasma exchange in the subpopulation of patients with anti-interferon autoantibodies and severe COVID-19 hospitalized in intensive care and on oxygen therapy, high flow or not, receiving non-ventilation or invasive ventilation, on D28 survival.
The primary objective of this project is to evaluate the role of patient navigation in promoting timely follow-up of abnormal breast imaging findings in patient populations that have been most severely impacted by the novel coronavirus (COVID-19) pandemic. This project aims to assess the impact of patient navigation as an intervention tool in patient populations that are most at risk for delayed follow-up. The investigators hypothesize that patient navigation services may be an effective way to mitigate the impact of the pandemic by decreasing the risk of a delayed breast cancer diagnosis and promoting timely diagnostic follow-up.
The research will be retrospective, and will include all patients who were admitted during 2020 and 2021 in the COVID-19 ICU of University Hospital Center Osijek due to pneumonia caused by the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The association of chest x-ray infiltrate evolution with changes in laboratory inflammatory parameters and respiratory function parameters will be examined.
A subset of patients with COVID-19 develops acute respiratory failure and acute respiratory distress syndrome (ARDS) (1). The use of invasive mechanical ventilation for the treatment of these conditions is associated with high mortality rates (2,3). The use of high-flow nasal oxygen therapy (HFNO) and awake prone position (AW-PP) could to decrease the need for endotracheal intubation and other adverse clinical outcomes (4-6). The aim of this study is to evaluate the clinical results of the simultaneous application of high-flow nasal oxygen therapy HFNO and awake-prone position in a cohort of patients with severe respiratory failure secondary to COVID-19 on relevant clinical outcomes, and to assess risk factors of treatment failure defined as requirement of invasive mechanical ventilation.
