Raw Data for the article: Usefulness of longitudinal systolic strain and delayed enhancement cardiac magnetic resonance in depicting risk of supraventricular arrythmias in patients with acute myocarditis and preserved left ventricular function
<p><strong>Background: </strong>Myocarditis have variable clinical presentation, evolution and prognosis. Aim of our study was to evaluate the value of speckle tracking echocardiography and cardiac magnetic resonance (CMR) in the short-term prediction of supraventricular arrhythmias (SVA) in patients with acute myocarditis.</p> <p><strong>Methods: </strong>Seventy patients (mean age 31±14 years old) with acute myocarditis and preserved left ventricular ejection fraction (LVEF) were enrolled. Longitudinal systolic strain (LS) of the left ventricle (LV), mechanical dispersion (MD) and CMR with quantitative measurement of delayed enhancement (DE) were performed in a subset of 43 patients. Logistic regression and ROC analysis were used to identify predictors of SVA RESULTS: Only LS measured at sup-epicardial, mid-wall and sub-endocardial level of the apical 4-chamber view was significantly lower in patients with SVA, while MD was marginally prolonged in this setting. A value of LS > - 16.1% measured at LV mid-wall in the apical 4-chamber view (ROC-AUC .75, Sensitivity 63%, Specificity 85%) was the most accurate measure to identify patients with SVA. DE mass was also helpful with a ROC-AUC .76; a DE-Mass > 18.9 gr. had a Sensitivity 63% and a Specificity 77%, to identify patients at risk of SVA.</p> <p><strong>Conclusions: </strong>Both DE mass and LS were associated with higher risk of SVA in patients with acute myocarditis and preserved LVEF. However, LS measured at the mid-wall level and limited to LV segments included in the apical 4-chamber view was the most accurate measure and did not show interaction with DE mass.</p>
BeMe-Lab (v25.06.02 SysTol 2025)
<p>BeMe-Lab (Bèvar Méjo-Lab) is a comprehensive Zenodo repository documenting all results and outputs from the author's PhD research. The repository contains conference abstracts, presentation slides, and dataset snapshots captured during manuscript preparation. Additionally, it includes Jupyter notebooks for data inspection, figure reproduction, and supplementary information that extend published works with details that could not fit within publication space constraints, including less prominent experiments and methodological insights.</p> <p>The repository is organised by research milestones ("Events") such as conferences, paper submissions, and other significant PhD journey markers. Individual abstracts, papers, and related outputs may have dedicated Zenodo entries with associated DOIs.</p> <p>This collection will be a valuable resource for the author's thesis writing and researchers working on Water Distribution System optimisation, providing comprehensive documentation of the research process and findings.</p>
Postural fall in systolic blood pressure is an useful warning sign in Dengue fever
<p><strong>Purpose</strong>: Capillary leak is the hallmark of development of severe dengue. A rise in hematocrit has been a major warning sign in WHO guidelines. Postural hypotension, which could reflect the intravascular volume reduction in capillary leak, has been noted as a warning sign in CDC and Pan American Health Organisation guidelines. We evaluated the diagnostic accuracy of Postural hypotension as a marker of development of severe dengue.</p> <p><strong>Methods</strong>: 150 patients admitted with dengue fever were recruited in this prospective observational study. Diagnostic accuracy of conventional warning signs (<span>abdominal pain, persistent vomiting, fluid accumulation, mucosal bleeding, lethargy, liver enlargement, increasing hematocrit with decreasing platelets)</span> and postural hypotension was evaluated.</p> <p><strong>Result</strong>: 23 (15.3%) subjects developed severe dengue. Multiple logistic regression analysis showed that Ascites/Pleural effusion and postural fall in systolic blood pressure of >10.33% had an odds ratio of 5.024(95%CI:1.11 – 22.75) and 11.369 (95% CI:2.27 – 56.87) respectively. Other parameters did not reach statistical significance. Sensitivity and specificity of Ascites/Pleural effusion were 82.6% and 88.2% for development of severe dengue, whereas postural fall in systolic blood pressure had sensitivity and specificity of 87% and 82.7%.</p> <p><strong>Conclusion</strong>: These findings present a strong case for including postural hypotension as a warning sign in patients with dengue fever, especially in resource-limited settings.</p>
