Efficacy and safety of covid-19 vaccine in Cardiac patients

NCT ID: NCT05348616 Not yet recruiting - RSV Infection Clinical Trials

Impact of the Covid-19 on RSV

IPCoVRS-2
Start date: May 2022
Phase:
Study type: Observational

The magnitude of seasonal RSV epidemics brings each year new logistical challenges for the hospitalization of young infants with bronchiolitis that overwhelm hospital capacities and lead to specific winter plans with deprogramming and mobilization of human and logistical resources. The Covid-19 pandemic has changed the way winter epidemics are presented. For example, the seasonal RSV epidemic was shifted by several months in Lyon, with an impression of a lower incidence of hospitalized cases, with a population of older children and with fewer signs of clinical severity. This is largely attributable to the widespread use of barrier gestures and social distancing measures, known as "non-pharmacological interventions" or NPI. Given the magnitude of the reduction of the RSV epidemic, it is legitimate to analyze the benefits of NPIs to draw lessons for maintaining preventive measures around RSV-vulnerable populations; moreover, new preventive pharmacological interventions are soon to be marketed, whether they are particularly refined and long half-life anti-RSV monoclonal antibodies, RSV vaccines for mothers or for newborns and infants. In this perspective, it is crucial to properly define the populations at risk of severe disease to establish a legitimate hierarchy in the implementation of different preventive strategies. The study of the RSV epidemic is a high potential model because of the convergence of epidemiological, virological, and pharmacological knowledge. However, the study of the impact of the pandemic on the epidemiology of rhinovirus also seems promising because, for reasons unknown to date, it seems that the pandemic did not have the same reducing impact on the rhinovirus epidemic; in the latter case, the interest is to confirm the resistance of this virus and to look for more fundamental explanations, for example, on viral interactions. On a previous study (see NTC 04944160), 519 infants and children were recruited in the Pre-Covid-19 season population, and 277 infants and children were recruited in the first Per-Covid-19 season population. In the present study, the objective is to assess the epidemiology of RVS in infants from the birth cohorts of the tertiary teaching hospitals of Lyon, France, during the Pre-Covid-19 (2013-2020) and the Per-Covid-19 (2020-2025) years.

NCT ID: NCT05346042 Recruiting - COVID-19 Clinical Trials

Safe and Timely Cessation of Isolation of Patients With COVID-19 (The SCIP-COVID-19) Study

SCIP-COVID19
Start date: December 1, 2022
Phase:
Study type: Observational

Rationale: In the treatment, care and isolation of COVID-19 patients, one of the most important issues is determining the duration of infectiousness. The current Dutch guideline advises at least 14 days of isolation for seriously ill patients, which is the case for most admitted patients, and at least 21 days for intubated patients. It is believed that in most cases this isolation duration is too long, which is highly undesirable for patients staying in closed single-occupancy rooms. This is known to result in limited contact with healthcare workers (HCW) and to be associated with a higher level of depression among patients. The longer the isolation, the higher the workload for HCW and the higher the costs (e.g. with about 0.5 million admission days in the Netherlands, these work out at about €14 million on personal protective equipment [PPE] and cleaning alone). Additionally, isolation demands a larger healthcare workforce, yielding less capacity to provide other care to non-COVID-19 patients, with numerous other consequences. On the other hand, it is possible that some patients were discontinued from isolation too early, leading to a risk of transmission to other patients and to HCW. In conclusion, duration of isolation should be as short as possible for proper patient flow and to avoid unnecessary burden to patients and HCW, and thus to healthcare in general. Therefore, there is an urgent need to define the period of infectiousness of COVID-19. We will develop a safe and effective algorithm for decision on timely discontinuation of isolation of COVID-19 hospitalized patients. Objective: The ultimate goal of this project is to produce new evidence-based criteria for the termination of isolation of hospitalized COVID-19 patients that are safe (very low subsequent risk of transmission to other patients or healthcare workers) while reducing the number of unnecessary days in isolation (thereby improving quality of life of patients, reducing hospital costs, and making optimal use of the scarce number of isolation beds). Multiple sources of data and evidence will be integrated to arrive at these new criteria.

NCT ID: NCT05343962 Recruiting - Stroke Clinical Trials

Health Indicators and Patient Reported Outcomes. Identification of Significative Items Aimed at Improving Health Care Procceses.

OUTCOMES
Start date: March 1, 2022
Phase:
Study type: Observational

The objective of this study is to identify key indicators in the follow-up of subjects with different pathologies related to both the person's environment, as well as the perception of their health and general quality of life and related to their disease. To this end, a cross-sectional observational study of qualitative data collection through questionnaires, mostly validated, has been proposed to try to identify these indicators. Based on these questionnaires, the specific objectives of this study are as follows: - Unify questionnaires - Assess data quality - Identify key indicators, through a factor analysis - Design a second reduced version of the questionnaires collecting the key indicators and eliminating those items that are exclusive to each other. In order to identify the key indicators, it will be necessary to measure at least 30 subjects from each pathological group, as well as a cohort of at least 100 subjects without pathologies in order to validate and contrast the results. The subjects will be recruited through the own databases of participants in previous trials of the Institute of Biomechanics of Valencia, who have given written consent to be contacted in order to request their participation in any other study where their profile may fit. They will also be recruited and contacted through the collaborating associations (Parkinson Valencia Association, Valencian Diabetes Association, Consorci Hospital General Universitari de València, Arnau de Vilanova Valencia Hospital). The surveys will be included in an online platform specialized in the realization of questionnaires. This data will be exported for further storage, management and analysis. All information will be anonymized for processing and analysis, and may be used under the terms and conditions dictated by the current legal framework. To participate in the study, participants must accept the terms and conditions included in the first page of the survey embedded in the online platform, where the aspects related to the study methodology and the use of them data are exposed. The statistical analysis will treat the data provided by the variables and how they are related to each other, testing differences according to the characteristics of the patient and clinical indicators. For that, non-parametric techniques such as the χ² test, the Kruskal-Wallis test and cluster analysis will be used.

Immunogenicity and Safety of Fractional Booster Dose of COVID-19 Vaccines Available for Use in Pakistan/Brazil: A Phase 4 Dose-optimizing Trial

Start date: July 5, 2022
Phase: Phase 4
Study type: Interventional

Since the emergence of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen in late 2019, millions of people around the world have fallen ill and died from coronavirus disease 2019 (COVID-19), with variant-fueled case spikes causing repeated cycles of morbidity and mortality. The rapid development and emergency use authorization of vaccines against SARS-CoV-2 presents an enormous opportunity to protect populations, but bottlenecks in production have led to demand for vaccines that far outpaces supply. This project will investigate the immunogenicity of fractional doses of SARS-CoV-2 vaccines given a minimum of six months following an initial two-dose schedule or following natural immunity via documented infection. The consortium of research partners from the Sabin Vaccine Institute, Aga Khan University, Fundação Oswaldo Cruz (Fiocruz), and Stanford University will recruit volunteers to receive a full or fractional booster dose of BNT162b2, AZD1222 or Sinovac following receipt of their primary vaccination series or PCR-confirmed natural infection in Pakistan. The research team will follow participants for six months from boosting, with blood draws at baseline, 28 days, 3 months and 6 months, and measure sero-response rate (SRR) by anti-Spike immunoglobulin G (IgG) binding enzyme-linked immunosorbent assay (ELISA) with the ultimate aim of identifying whether fractional doses provide a similar immune response compared to full doses of vaccine.

NCT ID: NCT05341713 Completed - Clinical trials for Vaccine Adverse Reaction

Epileptic Seizure in Epilepsy Patients After SARS-CoV-2 Vaccination

Start date: January 1, 2022
Phase:
Study type: Observational

Background and Objectives: Seizure attack is one of adverse effects of vaccination in epileptic patients, the risk of which after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inoculation was elucidated in the present study. Methods: A self-controlled case series study was designed to examine the association between vaccination and epileptic seizure. A total of 240 epilepsy patients were included who were vaccinated with inactive SARS-CoV-2 vaccines (Sinovac Life Sciences and Lanzhou Institute of Biological Products) and admitted to outpatient clinics from July 2021 to December 2021. Poisson analysis was performed to estimate the relative incidence rate of epileptic seizure in risk periods (day 1-7, 8-21 and 1-21 after first-dose vaccination) compared to basal level in control period.
