Risultati per: Trattamento domiciliare di un paziente positivo al virus SARS-Cov-2

Circulation, Volume 150, Issue Suppl_1, Page A4138507-A4138507, November 12, 2024. Background:SARS-CoV2 infection has been associated with cardiovascular consequences, including myocarditis and cardiac arrhythmias. Myocarditis secondary to SARS-CoV2 infection and cardiac arrhythmias may often go unrecognized and can present with late and nonspecific symptoms. Predicting those at risk allows for prompt treatment and prevention of their potentially life-threatening consequences.Methods:The National COVID Cohort Collaborative (N3C) database was used to identify patients aged 0-30 years with COVID-19 index date between 1/1/2020 and 3/31/2022, whose sites provided data for at least six months beyond the index date. Outcomes included myocarditis and new arrythmias within 6 months of the index visit. Patients with known cardiac comorbidities were excluded. Predictors included gender, race, COVID severity as an ordinal scale, vaccination status, clinical comorbidities, and Area Deprivation Index (ADI). The data were stratified by age groups (0-4, 5-17, 18-30). Random forest models were used for data analysis and SHapley Additive exPlanations (SHAP) method was applied to optimize results. These analyses were conducted using the NCATS N3C Data Enclave.Results:Of the 1,487,741 patients in our study population, 4,105 (0.28%) had the measured outcomes; 404 had myocarditis only, 3,634 had arrhythmia only and 67 had both. Severity of COVID (SHAP 0.2344 for 0-4 years, 0.2114 for 5-17, 0.1370 for 18-30) was identified as the most important risk factor for de-novo myocarditis and arrhythmias overall. Increase in ADI (indicating lower socioeconomic status) was the second most important risk factor for the 0-4 and 5-17 age groups (SHAP: 0.0370, 0.0223). Among the 18-30 age group, race (SHAP 0.0321) and gender (SHAP 0.0289) were the second and third most important risk factors, with White and Black patients more likely to develop an event and Hispanic patients less likely. Women were less likely to develop a cardiac outcome than men.Conclusion:The severity of COVID was identified as the most important risk factor for the occurrence of myocarditis or cardiac arrhythmia within 6 months of infection. ADI, race, and gender were also identified as important, though less influential, risk factors.

Introduction
Hepatitis C virus (HCV) infection is a silent epidemic that needs a comprehensive and contextualised approach to manage. Access to readily available, affordable and acceptable HCV point-of-care (POC) in vitro diagnostics (IVDs) is equally required to meet the global HCV goals. However, most guidelines for evaluating these IVDs such as the WHO prequalification process and country-specific standards disproportionately focus on diagnostic performance. The real-time connectivity, ease of specimen collection, affordability, sensitivity, specificity, user-friendliness, rapidity and robustness, equipment-free or simplicity and deliverability to end-users (REASSURED) criteria provide a holistic and user-oriented evaluation of the IVDs in the populations they are meant to be used. Therefore, as part of a multinational study in sub-Saharan Africa, we will conduct an evaluation of the Bioline HCV POC test for diagnosing HCV infection in primary healthcare settings of Ghana using the REASSURED criteria.

Methods and analysis
This field evaluation will be conducted in three phases. The first phase will use a cross-sectional field evaluation study design to evaluate the diagnostic performance of the Bioline HCV POC test. The second phase will use mixed methods to ascertain operational characteristics and users’ perceptions. In the third phase, a cross-sectional survey will be used to estimate the costs of accessing HCV diagnostics services using three proposed HCV testing models to inform the affordability of the testing pathways and linkage to care in the primary healthcare clinics. This phase will run concurrently with the second phase of the study. Thematic content analysis and quantitative data analysis will be performed using ATLAS.ti V.23.0.6 and StataCorp LLC’s Stata statistical software V.16.0, respectively.

Ethics and dissemination
The study protocol has been reviewed and fully approved by the Faculty of Health Sciences Research Ethics Committee, University of Pretoria (281/2023) and the Ghana Health Service Ethics Review Committee (GHS-ERC013/08/23). This diagnostic trial has also been registered in the Pan African Clinical Trial Registry (PACTR202410837698664). The findings of the study will be presented in relevant peer-reviewed journals, at local and international conferences, and to all stakeholders involved.

Several new tick-borne viruses have been discovered in various parts of the world in the past 10 years. The latest may be a previously unknown orthonairovirus known as Wetland virus (WELV).

This cohort study examines cardiovascular complications of postvaccine and other types of myocarditis (ie, post–COVID-19 and conventional myocarditis) during 18-month follow-up.
