Filter by:Mixed-method observational study: the impact of pandemic related changes in healthcare on quality of life and experiences with healthcare in Dutch patients undergoing surgery or another intervention during the covid pandemic (2020-2021). Phase 1: qualitative study to gain insight in relevant themes in Patient Reported Experiences Measures (PREMs) by conducting focus groups Phase 2: creating and validating a questionnaire based on themes identified in phase 1 Phase 3: questionnaire study among Dutch patients who underwent an intervention in 2020-2021 using the validated questionnaire of phase 2. The answers will be linked to data from national patients registries in surgery, cardiology, orthopedics and neurology.
A Global Multi-center, Randomized, Blinded, Placebo-controlled Phase 3 Clinical Study to Evaluate the Efficacy, Safety and Immunogenicity of SARS-CoV-2 mRNA Vaccine (LVRNA009) for the Prevention of COVID-19 in Participants Aged 18 Years and Older
The study will evaluate the safety, tolerability, reactogenicity, and effectiveness of mRNA-1273.214 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine in infants aged 12 weeks to < 6 months.
The purpose of the study will be to evaluate the effect of a rehabilitation program on the improvement of patients with post-COVID-19 musculoskeletal symptoms, as well as to quantify the impact of telemedicine that evaluates the evolution of pain, functionality, and quality of life.
This study plans to enrol 1000 participants 18 years and above, with ≥10% participants ≥60 years old. According to SARS-CoV-2 vaccine vaccination history, they will be evenly divided into 2 groups, Group A and Group B. Group A: will enrol 500 participants who have received 2 doses of inactivated SARS-CoV-2 vaccine according to national immunization planning, whose last dose was given at least 6 months ago. They will be given one dose of the study vaccine (SYS6006) after enrolment. Group B: will enrol 500 participants who have received 3 doses of inactivated SARS-CoV-2 vaccine according to national immunization planning, whose last dose was given at least 6 months ago. They will be given one dose of the study vaccine (SYS6006) after enrolment. The study is devided into two stages, the first stage will enrol 200 participants with 100 in Group A and 100 in Group B. They will undergo laboratory examination, immunogenicity observation and safety observation. The first 30 participants in each group will take extra cellular immune testing; the second stage will enrol the remaining 800 participants for safety observation.
This study will evaluate the safety and immunogenicity of the mRNA-1273.214 vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of concerns (VOCs) in participants aged 6 months to <6 years, when administered as a primary series in SARS-CoV-2 vaccine-naïve participants (Part 1) and a single booster dose (BD) given to participants who previously received 2 doses of the mRNA-1273 vaccine as a primary series (Part 2); and will evaluate the safety and immunogenicity of the mRNA-1273.815 vaccine, when administered as a BD in participants aged 6 months to <6 years (Part 3) and when administered to SARS-CoV-2 vaccine-naïve participants aged 2 years to <5 years of age (Part 4).
The COVID-19 infection affects humans differently. While some recover quickly and fully, others develop serious illnesses and late complications. The term late complications describe symptoms that last for 12 weeks or longer after COVID-19 infection is detected. The aim of the present project is to investigate whether it is possible to identify genetic factors that occur more frequently in people suffering from COVID-19 late complications than in those who do not develop late complications. The investigators aim to develop a genetic profile that identifies individuals at high risk for late complications of COVID-19. Number and nature of late complications will be analyses to identify patterns in the incidence of late complications associated with certain genetic traits. The study is designed as a case-control study and is expected to include 500 subjects between 18 and 65 years of age who at least 12 weeks ago tested positive for COVID-19; 250 who suffer from late complications and 250 who have fully recovered.
Vaccination is the best way to mitigate the coronavirus disease 2019 (COVID-19) pandemic, but the vaccine immunogenicity may be quite variable from person to person. There is increasing evidence suggesting that the gut microbiome is a major determinant of vaccine immunogenicity. Thus, the investigators investigated the relationship between gut microbiota and humoral immune response after COVID-19 vaccination.
Vaccines against the coronavirus type 2 causing severe acute respiratory syndrome Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) have been created in a short period of time due to the rapid spread of the virus. These vaccines use different and sometimes innovative technologies, such as the use of ribonucleic acid (RNA), or a non-replicating viral vector. Efficacy ranging from 70-90% in the first weeks after the second injection of these vaccines has been reported, with side effects whose causality remains to be determined.
SARS-COV-2 infection is responsible for a potentially severe primarily respiratory infection called COVID19. A large proportion of patients, in particular in severe forms, present with thrombotic manifestations (DVT, EP, stroke, thrombosis of dialysis circuits, etc.). A significant proportion is also a carrier of circulating anticoagulant (ACC or LA), making it possible to suggest a diagnosis of APS. This type of autoantibody results in a spontaneous prolongation of the TCA uncorrected by a control serum therefore is quickly diagnosed using standard hemostasis The objective of this study is to describe the diagnosis of thrombotic complications in COVID19 patients presenting a positive lupus anticoagulant type test (LA) or aPL and the associated clinical and biological elements that may have favored thrombosis.
