Filter by:Subjects who have completed the primary mRNA vaccine immunizations and the 1st booster AZD1222 immunization for more than 6 months will be randomized to receive a 2nd booster dose of Ad5-nCoV/O, Ad5-nCoV/O-IH or mRNA-based COVID-19 vaccine in a ratio of 2:2:1.
In the absence of data on Electric impedance tomography of healthy spontaneous breathing patients that is compared to dyspnoeic patients suffering from postacute COVID-19 syndrome, the investigators contend that electrical impedance tomography provides additional clues to visualize regional lung ventilation and differentiate healthy from sick patients.
Evaluation of the reciprocal relation between hyperglycemia/diabetes mellitus (HG/DM) and COVID-19 disease and the effect of mode of insulin therapy; intensive (IIT) or conventional (CIT) on patients' outcomes All patients admitted to the quarantine hospitals with mild-severe COVID disease were evaluated using the COVID-GRAM Critical Illness Risk Score and gave blood samples for estimation of random blood glucose. Diabetic patients and non-diabetic patients with persistent HG were randomly divided according to mode of IT. Patients who were free HG were included as control normoglycemic (NG) patients. Study outcomes included the incidence of progress to critical illness and mortality rate (MR), and the effect of IT on such outcomes
This is a phase 2, randomized, observer-blinded, placebo-controlled clinical study to evaluate the immunogenicity and safety of SARS-CoV-2 mRNA Vaccine (SYS6006）in healthy participants aged 18 or more.
There is objective need to examine nutritional status (i.e., body mass index (BMI), body composition and dietary intake) of healthy adult Slovenes after SARS-CoV-2 (Covid-19) epidemic period. In the Slovenian (pair of European Union) adult population (with only 2 million inhabitants), we do not yet have representative data on the body composition of adult Slovenes published in the scientific literature. In the study after the Covid-19 pandemic period (4th wave) the investigators will use medically approved body analyzer (Tanita 780 S MA, Tokyo, Japan) and standardized food frequency questionnaire (FFQ). In addition, the investigators will measured body height of the participants with a portable altimeter (ADE MZ10042, Germany). The research will include randomly recruited adults (participants) who will attend various free or/and paid publicly available seminars, congresses and fairs in Slovenia, directly unrelated topics to physical activity or healthy eating (i.e., healthy and active lifestyle) thus obtaining a more realistic current population status.
The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called Nirmatrelvir/Ritonavir) for the possible treatment of COVID-19. Patients with COVID-19 who have more difficulty in fighting against infections have a higher chance of severe illness. Such patients may benefit from longer treatment durations compared to the standard treatment regimen. The study is seeking participants who: - Have a confirmed COVID-19 infection - Are Immunocompromised - Experience onset of signs/symptoms attributable to the current COVID-19 infection within 5 days prior to screening and ≥1 signs/symptoms attributable to COVID-19 present on the day of randomization. In addition, this study will also evaluate the efficacy and safety of a second treatment course of nirmatrelvir/ritonavir in people who experience that their COVID-19 is flaring up within 14 days of having taken a 5-day treatment course of nirmatrelvir/ritonavir. For this group, the study is seeking participants who: - Have a confirmed COVID-19 infection - Experience a worsening of signs/symptoms after completing an initial 5-day course of nirmatrelvir/ritonavir - The worsening of COVID-19 symptoms must occur within 14 days after completion of the initial 5-day course of nirmatrelvir/ritonavir - Are Immunocompromised - Experience onset of signs/symptoms attributable to the current COVID-19 infection within 48 hours prior to screening and ≥1 signs/symptoms attributable to COVID-19 present on the day of randomization. All participants will be taking the study medicine for either 5, 10, or 15 days. The study medication will be taken by mouth 2 times a day. Participants will take part in this study for about 24 weeks. The first dose of study medication is taken at the study site and the rest at home. Selected participants will need to visit the study site at least 10 times during the study.
This is a prospective, multicentre study in which the diagnostic accuracy of multiple Covid-19 Antigen rapid diagnostic tests will be assessed for COVID-19 case detection using prospectively collected nasal swabs and saliva samples from participants suspected to have Covid-19 infection (with or without symptoms). The study will last approximately 9 months.
If a treated cancer patient cannot make antibodies to a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Emergency Use Authorization (EUA) or approved vaccine, their risk for infection and its sequelae are significantly increased. The Astra-Zeneca Immuno-Suppressed Program (AISP) is designed to address whether a patient treated for cancer who receives a single-dose of Evusheld (AZD7442) 600 mg IM or IV will maintain a stable/protective effect against symptomatic SARS-CoV-2 infection including SARS-CoV-2 related hospitalization and/or SARS-CoV-2 related death up to 12 months post-baseline. The program will focus on patients with cancer who have been treated with chemotherapy, immunotherapy, targeted therapy, other therapy or combination therapy with or without radiation therapy within 12 months prior to enrollment, are willing/able to receive one IM or IV injection of Evusheld, are able to complete 14 Patient Experience/Clinical Outcome Assessment (COA) surveys, 6 Quality of Life (QoL) assessments and are willing to allow serum concentrations of Evusheld to be drawn 9 times, 3 SARS-CoV-2 Receptor Binding Domain-Immunoglobulin G (RBD-IgG) tests, and T-cell assay to be drawn once. In the event of a symptomatic break-thru SARS-CoV-2 positive infection by SARS-COV-2 Ribonucleic Acid (RNA) by Reverse Transcription Polymerase Chain Reaction (RT-PCR) test, the patient will have an additional Evusheld serum concentration, SARS-CoV-2 RBD-IgG antibody level and T-cell assay obtained in a temporally related manner. The program requires treatment with Evusheld 600 mg IM or IV.
This study evaluates the incidence, patient characteristics and outcome of myocarditis after the COVID-19 mRNA vaccination in healthcare professionals.
