Aim: To assess the diagnostic accuracy of computed tomographic venography (CTV) for splanchnic vein thrombosis (SVT) detection in necrotizing acute pancreatitis (AP) patients.
Methods: Forty-three patients with necrotizing AP who underwent both CTV and digital subtraction angiography (DSA) within 3 d were analyzed in this retrospective comparative study. All CTV procedures were performed with a dual-source CT scanner. The presence and location of SVT were determined via blinded imaging data analyses.
Results: According to the DSA results, 17 (39.5%) of the total 43 patients had SVT. The sensitivity, specificity, positive and negative predictive values of CTV for SVT detection were 100% (95%CI: 77.1%-100%), 92.3% (95%CI: 73.4%-98.7%), 89.5% (95%CI: 65.5%-98.2%) and 100% (95%CI: 82.8%-100%), respectively.
Conclusion: CTV is an effective examination for SVT detection in patients with necrotizing AP with high positive and negative predictive values.

Utility of using far-field R-wave signals in the detection of fatal ventricular arrhythmia.

Current guidelines recommend cardioverter-defibrillator (ICD) programming, including faster detection rates, longer detection durations, and strict discrimination for supraventricular tachycardia (SVT) to prevent unnecessary ICD treatment. This delayed-style ICD programming could lead to a rise in the possibility of VF undersensing. To avoid this risk, an innovative algorithm known as VF Therapy Assurance (VFTA; Abbott, Sylmar, CA) has been developed.

Purpose: This study explores the use of heart rate variability (HRV) analysis, a noninvasive technique for assessing the autonomic nervous system, by applying nonlinear dynamics and chaos theory to detect chaotic behavior in RR intervals and assess cardiovascular health.
Methods: Employing the "System Analysis of Heart Rate Dynamics" (SADR) program, this research combines chaos analysis with the short-time Fourier transform to assess nonlinear dynamic parameters in HRV. It includes constructing phase portraits in Takens space and calculating measures of chaos to identify deterministic chaos indicators.
Sustained Ventricular Tachycardia as the first presentation of transthyretin amyloid cardiomyopathy.

Transthyretin Amyloid Cardiomyopathy (ATTR-CM) was considered an uncommon disease until a few years ago, but advances in the epidemiology and non-invasive diagnostic tests have increased its timely detection. We report a 71 years-old man with history of hypertension and an incidental carcinoma of the left kidney detected 6 years ago, without heart failure who was performed cardiac magnetic resonance images (MRI) by suspicion of hypertrophic cardiomyopathy. Before his cardiologist be aware of the result, he suffered a severe sustained ventricular tachycardia (SVT) that required emergency cardioversion.

Diagnostic Department, Veterinary Public Health and Preventive Medicine Division and Pathology Division, National Veterinary Research Institute, Vom, Nigeria.
Background: After the first Avian Influenza H5N1 outbreak in Nigerian poultry in 2006, subsequent waves of outbreaks occurred, causing substantial losses. Despite effective control measures by 2008, a resurgence in 2015 led to further losses and required depopulation efforts.
Aim: The aim of this study was to do pathology and molecular detection of influenza A subtype H9N2 virus in commercial poultry in Nigeria during 2024.
