Article Abstract
Background: Dengue fever is a zoonotic viral infection that raises a global alarm in the tropics and subtropics, with the potentially escalating into newer geographical regions. Severe dengue may be associated with fatal complications such as myocarditis. There is a paucity of available data on the prevalence of dengue-associated myocarditis. The objective of this systematic review and meta-analysis was to estimate the global prevalence of dengue-associated myocarditis.
Methods: A systematic search was conducted utilizing the Cochrane library, PubMed, Scopus, ProQuest, Web of Science, and Preprint servers such as arXiv, medRxiv, bioRxiv, BioRN, ChiRN, ChiRxiv, and SSRN as of November 25, 2022. All primary studies (case series, cross-sectional, retrospective, and prospective) that reported confirmed cases of dengue myocarditis were included. The I statistic test assessed the heterogenic characteristics and publication bias was evaluated using Doi plot and Egger regression tests.
Results: A total of 12 studies conducted between 2007 and 2022 with 2795 laboratory-confirmed dengue patients were included. Of the included cases, 502 were positive for myocarditis, with a prevalence of 2.4-78%. The pooled prevalence of dengue-induced myocarditis in the studied population was 21.0% (95% CI, 9 - 38%). The prediction interval was estimated to be 0.00 - 0.81.
Conclusion: Myocarditis in dengue patients is a significant and understudied complication in many aspects. To prevent dengue-associated myocarditis, appropriate measures such as early detection of cases and signs, symptoms-based diagnosis via electrocardiography and echocardiography, as well as relevant vector control policies must be implemented.

From Gut Inflammation to Cardiovascular Conflagration: Mapping IBD's Cardiometabolic Risks.
Curr Atheroscler Rep

Division of Gastroenterology and Hepatology, Lynda K. and David M. Underwood Center for Digestive Health, Houston Methodist Hospital, Houston, TX, USA.
Purpose Of Review: This review aims to characterize the known cardiovascular (CV) manifestations associated with inflammatory bowel disease (IBD) and the underlying mechanisms driving these associations.
Recent Findings: Gut dysbiosis, a hallmark of patients with IBD, can result in both local and systemic inflammation, thereby potentially increasing the risk of cardiovascular disease (CVD) in the IBD population. Micronutrient deficiencies, anemia, and sarcopenia independently increase the risk of CVD and are frequent comorbidities of patients with IBD.

Background And Aims: Fulminant myocarditis (FM) is a complex clinical syndrome characterized by acute myocardial inflammation and cardiogenic shock. Evidence on long-term outcomes, mortality risk factors, and targeted treatment options remains limited.
Methods: This retrospective analysis included consecutive adult patients admitted for FM between January 2012 and November 2022 at 26 European tertiary centres.

Fulminant myocarditis is characterized by an extremely severe course and remains a life-threatening disease. Only isolated cases of diffuse myocardial calcification in myocarditis have been reported. For this reason, the process of natural evolution of myocardial structural changes and their impact on the cardiovascular system have not yet been sufficiently studied.

Background: Cardiac laminopathies, associated with mutations in the LMNA gene, are a rare inherited disorder characterized by a broad range of clinical manifestations. There are currently no data on the association between supraventricular re-entrant tachycardias and LMNA-related cardiomyopathy.
Case Summary: A 26-year-old male presented with either wide-QRS tachycardia with a left bundle branch block (LBBB) pattern or narrow QRS tachycardia, as well as a history of palpitations since age 15.

Purpose: This research aimed to investigate the association between neutrophil-percentage-to-albumin ratio (NPAR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and aggregate index of systemic inflammation (AISI) with disease severity in patients diagnosed with acute myocarditis.
Methods: A total of 185 patients were diagnosed with acute myocarditis at the First Hospital of Jilin University between 2018 and 2024. The related values of NPAR, SII, SIRI, and AISI were computed based on the pertinent blood indices that were acquired within 12 hours of admission.
