Filter by:COVID-19 is the infectious disease caused by the novel coronavirus known as SARS-CoV-2, that appeared in 2019. The World Health Organisation (WHO) declared the novel coronavirus a pandemic on 11 March 2020. The evolution of the pandemic is varying across countries, affected in part by different containment strategies ranging from extreme lockdown to relative inaction. As a result, there are regional waves of the disease and pockets of vulnerable populations. Globally, governments have acknowledged that effective vaccines against COVID-19 are the only way to guarantee a safe and sustained exit strategy from repeated lockdowns. The objective of this study is to estimate the vaccine effectiveness against hospitalizations due to circulating COVID-19 VoC among subjects eligible for vaccination with the AstraZeneca or any other COVID-19 vaccine provided in their country as per national/regional immunization recommendations prior to hospital admission. The study design is an observational prospective active-surveillance hospital-based study, with a test-negative case-control design (TNCC) of hospitalized COVID-19 like cases undergoing testing for SARS-CoV-2
To investigate the effect of yoga-based exercises therapy on functional capacity, dyspnea, quality of life, depression, anxiety, and sleep quality in healthcare professionals following COVID-19.
Exercise intolerance and fatigue are the most common symptoms in patients with chronic COVID after hospital discharge. Muscle deconditioning, dysautonomia, and exercise hyperventilation have been proposed as potential mechanisms contributing to exercise functional capacity limitation in Long-COVID. Along this line, combined exercise training or inspiratory muscle training (IMT) alone have already been demonstrated to be feasible therapeutic options for Long-COVID patients. However, we do not have evidence about the effects of a home-based IMT program for 12-week on peak oxygen consumption (peakVO2). in patients chronic COVID (>3 months) after hospital discharge. This is a prospective study, blinded for the evaluator, randomized (1:1) to receive standard management alone or combined with a program of IMT that will be carried out in a single center. After randomization, patients will be clinically evaluated. The primary endpoint (peakVO2) will be assessed by cardiopulmonary exercise testing (CPET) at 12-week. Patients with chronic COVID (>3 months) after hospital discharge will be enrolled. A sample size estimation [alfa: 0.05, power: 80%, a 15% loss rate, and at least a delta change of mean peakVO2: +3 mL/kg/min (SD±2.5)] of 26 patients (13 per arm) would be necessary to test our hypothesis.
The COVID-19 pandemic has created a shift in the use of at-home spaces for work, play and research. In the current study, the feasibility of implementing an at-home cognitive training tool called NeuroTrackerX, an anaglyph version of the three-dimensional multiple object tracking (3D-MOT) software NeuroTracker was examined, and with the intent of developing an effective protocol and determining the suitability of this tool for research purposes .
This research aims to investigate the adjuvant effect of LH in reducing the symptomatic duration of fully vaccinated, mild COVID-19 patients on home recovery program in Singapore. It is aimed to assist policymakers in incorporating clinically proven TCM treatment for mild COVID-19 patients on home recovery program, and establishing a guideline on TCM pandemic treatment protocol which is suitable to be integrated into the healthcare system.
Coronavirus disease 2019 is a novel viral disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 virus. The original cases occurred in Wuhan, China, in December 2019 and rapidly spread to other areas worldwide, constituting a pandemic with unimaginable health and economic consequences. the World Health Organization elevated the disease to the category of a pandemic on March 11, 2020. In children, the reported mortality rates were far below 1%, while in people above the age of 70 years it was above 5% or higher. So, in this retrospective study, the investigators describe the clinical features and outcomes of children with chronic kidney diseases who were diagnosed with Severe Acute Respiratory Syndrome Coronavirus 2 infection at pediatric centers in Doha from 1st March 2020 till January 20th, 2022. This review looks into the literature on pediatric patients with chronic kidney diseases to verify whether they were more prone to developing more severe symptoms when diagnosed with Coronavirus disease 2019 compared to children without chronic kidney diseases and adults with chronic kidney diseases, and the Prevalence of COVID-19 infection between patients with chronic kidney diseases, and the role of COVID-19 infection in increasing the relapses and deterioration of chronic kidney diseases.
Hypocalcemia is associated with COVID-19 patients and is linked to poor prognosis, Fibroblast growth factor 23 (FGF23) and Sclerostin inhibit vitamin D activation and are linked to hypocalcemia. Levels of FGF23 and Sclerostin in COVID-19 patients will be detected and correlated to calcium levels.
This is a study of two experimental SARS-CoV-2 vaccines against the virus called SARS-CoV-2 virus. The first of the experimental vaccines is called DoCo-Pro-RBD-1 + M59® and contains a laboratory made protein which looks the same as a protein in the SARS-CoV-2 virus. As this protein is so similar to a protein in the SARS-CoV-2 virus, it allows the immune system to develop immunity against the real virus by producing specific antibodies against this protein. Antibodies are substances in the blood which could help protect against future infection. The second of the experimental vaccines that will be tested is called MIPSCo-mRNA-RBD-1. This type of vaccine uses messenger ribonucleic acid (mRNA) which is a set of instructions for a cell to make a viral protein called an antigen. Antigens are substances that can trigger the body's defences to produce antibodies that fight against the disease. This study will test these two experimental COVID-19 vaccines in people who have previously received two doses of ComirnatyTM (Pfizer Australia Pty Ltd) or VaxzevriaTM (AstraZeneca Pty Ltd) and a third booster vaccination with either ComirnatyTM or SpikevaxTM (Moderna). This study is the first time this recombinant protein vaccine and this mRNA vaccine will be given to humans. The purpose of this study is to determine what amount, or dose, of the experimental vaccines is safe and produces the desired immune response and antibody level for future investigations. It will do this by testing 3 different dose levels for each of the two vaccines. Each participant will receive a single vaccine at one of the three dose levels, or a placebo injection. This study is the first time this recombinant protein vaccine and this mRNA vaccine will be given to humans.
The COVID-19 pandemic ravaged United States skilled-nursing facilities (SNFs). Novel strategies that maximize the safety and quality of life for SNF residents with ADRD and staff who care for them are urgently needed. Thus, the study's objectives are: 1. To rapidly plan and pilot test an intervention that leverages COVID-19 antibody and PCR status to pair SNF staff with residents in the safest way possible 2. To reduce reduced COVID-19 incidence rate compared to SNFs not using this novel staff-resident assignment strategy.
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.
