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...

BACKGROUND: Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation for atrial fibrillation (AF). There are limited data on the PolarX Cryoballoon. AIMS: The study aimed to establish the safety, efficacy, and feasibility of same day discharge for Cryoballoon PVI. METHODS: Multi-centre study across 12 centres. Procedural metrics, safety profile and procedural efficacy of the PolarX Cryoballoon with the Artic Front Advance (AFA) Cryoballoon was compared in a cohort large enough to provide definitive comparative data...

BACKGROUND AND AIMS: A low resting heart rate (RHR) implies a more efficient heart function and a lower risk of cardiovascular disease. However, observational studies have reported a U-shaped association between RHR and atrial fibrillation (AF). In contrast, Mendelian randomization (MR) studies have found an inverse causal association between RHR and AF. Hence, the causal nature of the relationship is not clear. The aim is to investigate the causal association and its shape between RHR on AF using linear and non-linear MR (NLMR)...

AIMS: Heart failure with preserved ejection fraction (HFpEF) is a syndrome characterized by multiple cardiac reserve limitations during exercise. Cardiac power output (CPO) is an index of global cardiac performance and can be estimated noninvasively by echocardiography. We hypothesized that CPO reserve during exercise would be associated with impaired cardiovascular reserve, exercise intolerance, and adverse outcomes in HFpEF. METHODS AND RESULTS: Exercise stress echocardiography was performed in 425 dyspneic patients (217 HFpEF and 208 non-HF controls) to estimate CPO at rest and during exercise...

Coxsackievirus (CV) A6 is currently considered as a predominant pathogen of hand, foot, and mouth disease (HFMD), and is occasionally linked to myocardial injury. We first established a mouse model of CVA6-induced myocardial injury. Next, we analyzed the immune cell phenotypes CVA6-infected mice hearts by FACS, and found that CVA6 led to massive neutrophils infiltration, suggesting their potential link with the occurrence of myocardial injury. We further used either αGr-1 or αLy6G antibody to deplete neutrophils, and found that neutrophil-depleted animals showed decreased cardiac enzymes, lower degree pathology in hearts, and reduced inflammatory cytokine production compared to isotype controls...

The recent special issue of the World Journal for Pediatric and Congenital Heart Surgery devoted to hypoplastic left heart syndrome, and its related anomalies, contained significant information of great clinical relevance. Very little attention, however, was devoted to the integrity of ventricular septum as providing a criterion to distinguish between the phenotypes to be included within the syndrome, as opposed to the related anomalies. In this commentary, we summarize the evidence in support of the notion that the phenotypes to be included within the syndrome can be interpreted on the basis of an acquired disease of fetal life...

BACKGROUND: Simulation-based learning has been a valuable integrated part of simulation curricula. Simulation modalities include high-fidelity simulation (HFS), clinical skills (SK), standardized patients (SP), hybrid and combined simulation. HFS and SK are usually taught face-to-face and require specialized equipment. In response to the COVID-19 pandemic and lockdowns, efforts to develop distributed screen-based high-fidelity simulation accelerated to provide enhanced remote learning...

BACKGROUND: Risk factors for hypoxemia in school age children undergoing one-lung ventilation remain poorly understood. We hypothesize that certain modifiable and non-modifiable factors may be associated with increased risk of hypoxemia in school age children undergoing one-lung ventilation and thoracic surgery. METHODS: The Multicenter Perioperative Outcomes Group database was queried for children 4 to 17 years of age undergoing one-lung ventilation. Patients undergoing vascular or cardiac procedures were excluded...

BACKGROUND AND AIMS: Limited real-world data show that rivaroxaban following dosage criteria from either ROCKET AF (20mg/day or 15mg/day if creatinine clearance [CrCl]<50ml/min) or J-ROCKET AF (15mg/day or 10mg/day if CrCl<50ml/min) are associated with comparable risks of thromboembolism and bleeding with each other in patients with non-valvular atrial fibrillation (NVAF). We are aimed to study whether these observations differ between Asian and non-Asian subjects. METHODS: A systematic review and meta-analysis with random effects was conducted to estimate the aggregate hazard ratio (HR) and 95% confidence interval (CI) using PubMed and MEDLINE databases from September 8, 2011 to December 31, 2022 searched for adjusted observational studies that reported relevant clinical outcomes of NVAF patients receiving rivaroxaban 10mg/day if CrCl>50ml/min, on-label dose rivaroxaban eligible for ROCKET AF or J-ROCKET AF, and rivaroxaban 20mg/day if CrCl<50ml/min...

INTRODUCTION: Noninvasive tests, such as Fibrosis-4 (FIB-4), liver-stiffness measurement (LSM) by vibration-controlled transient elastography, and Fibroscan-AST (FAST), are frequently used for risk stratification in NAFLD. The comparative performance of FIB-4 and LSM and FAST to predict clinical outcomes of patients with NAFLD remained unclear. We aim to evaluate the performance of FIB-4, LSM, and FAST scores to predict clinical outcomes in patients with NAFLD. METHODS: We included consecutive adult patients with NAFLD with transient elastography performed between 2015 and 2022 from the United States and Singapore...

BACKGROUND: Limited knowledge exists regarding patients' denial of myocardial infarction (MI) before hospitalization for an MI. OBJECTIVE: The aim of this study was to determine the prevalence and correlates of denial of MI in the prehospital phase of a confirmed MI. METHODS: This secondary analysis included 166 hospitalized patients (mean [SD] age, 54.1 [10.5] years) who developed MI outside a healthcare facility and had high congruence between their experienced and expected symptoms...

OBJECTIVES: This study aimed to evaluate the clinical, laboratory and genetic characteristics, and outcomes of patients with AA amyloidosis (AA-a). METHODS: Patients followed-up in a tertiary referral center in Turkey with the diagnosis of inflammatory rheumatic diseases and immunohistologically proven AA-a were included into the study and retrospectively analyzed. RESULTS: Among 184 patients with the diagnosis of AA-a, 174 (F/M = 83/91) were included in the analysis...

Unsupervised domain adaptation (UDA) aims to train a model on a labeled source domain and adapt it to an unlabeled target domain. In medical image segmentation field, most existing UDA methods rely on adversarial learning to address the domain gap between different image modalities. However, this process is complicated and inefficient. In this paper, we propose a simple yet effective UDA method based on both frequency and spatial domain transfer under a multi-teacher distillation framework. In the frequency domain, we introduce non-subsampled contourlet transform for identifying domain-invariant and domain-variant frequency components (DIFs and DVFs) and replace the DVFs of the source domain images with those of the target domain images while keeping the DIFs unchanged to narrow the domain gap...
