Eosinophilic myocarditis: systematic review.

Objective: In clinical practice, patients with eosinophilic myocarditis (EM) may forgo the gold standard diagnostic procedure, endomyocardial biopsy (EMB), although it is highly recommended in guidelines. This systematic review aims to summarise current approaches in diagnosing and treating EM with a particular emphasis on the utilisation and value of alternative diagnostic methods.

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we searched MEDLINE and EMBASE for all peer-reviewed articles using the keywords "eosinophilic myocarditis" from their inception to 10 September 2022.

How effective is extracorporeal life support for patients with out-of-hospital cardiac arrest initiated at the emergency department? A systematic review and meta-analysis.

Background: Extracorporeal cardiopulmonary resuscitation (ECPR) is commonly initiated for adults experiencing cardiac arrest within the cardiac catheterization lab or the intensive care unit. However, the potential benefit of ECPR for these patients in the emergency department (ED) remains undocumented. This study aims to assess the benefit of ECPR initiated in the ED for patients with out-of-hospital cardiac arrest (OHCA).

Intravenous Iron for Heart Failure: Updated Systematic Review and Meta-Analysis.

While the administration of intravenous (IV) iron to those with heart failure has been implicated to be associated with a possible reduction in hospitalizations and improvement in symptoms, a recent large multicenter trial only showed modest benefits in reducing hospitalization, necessitating the updated systematic review. We conducted a systematic review and meta-analysis, searching the MEDLINE and EMBASE database until January 9, 2023. Outcomes included total heart failure hospitalizations, first heart failure hospitalization, six-minute walk test (6MWT) distance, and incidence of infection.

The risk of new heart failure associated with protease inhibitor: Systematic scoping review.

Background: Protease inhibitors (PIs) have contributed to the long-term survival of persons with human immunodeficiency virus (PHIV). While there is a concern linking protease inhibitors to an increased risk of heart failure (HF), the evidence linking protease inhibitors and heart failure has been uncertain.

Methods: Following the PRISMA Extension for Scoping Reviews, we searched MEDLINE and EMBASE for peer-reviewed articles using keywords including "protease inhibitor," "heart failure," and "human immunodeficiency virus" from their inception to December 21, 2022.

Bile Cast Nephropathy Because of Acute Liver Injury Associated With Selective Androgen Receptor Modulators.

Selective androgen receptor modulators (SARMs) are novel nonsteroidal agents abused for performance enhancement such as anabolic steroids. We report a case of a 27-year-old man who used 3 different SARMs and presented with progressive weakness. Initial laboratory testing showed kidney and liver injury with creatinine 4.

Atrial fibrillation catheter ablation in endurance athletes: systematic review and meta-analysis.

Background: Atrial fibrillation (AF) management in endurance athletes (EA) is challenging due to the paucity of data, especially on the efficacy and safety of catheter ablation (CA). The hypothesis is that the efficacy and safety of AF CA in EA are comparable to the non-EA.

Methods: Databases from EMBASE, Medline, PubMed, and Cochrane were searched from inception through February 2023.

Hamartoma of mature cardiac myocytes: systematic review.

Background: While primary cardiac tumors are rare, it has been increasingly recognized due to improvement in screening measures.
