Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death. Abdominal ultrasound (US) is by far the most widely used first-level exam for the diagnosis of HCC. We aimed to assess whether different ultrasound patterns were related to tumor prognosis.

- A new method for calculating foodborne disease risk scores in the food service industry has been developed to improve previous assessment techniques used during the World Cup in Brazil.
- The method utilizes a risk matrix based on item consequence and probability, validated through inspections of over 3,000 food service outlets.
- Results show strong agreement between the new risk scores and the old method, indicating this adaptable approach could serve as a model for food safety assessments globally.
Faced with a global pandemic such as the one triggered by the SARS-CoV-2 virus, the medical supply chain has been highly demanded. An item in which this manifested itself more clearly, are the N95 masks, designed to be disposable items, in many cases they have had to be reused. In these emergency conditions, it was necessary to apply an effective and safe method that can be used locally.

We aimed to assess the electrophysiological properties of CI channels during mapping with the IntellaMap Orion basket and the Rhythmia system.
Methods And Results: We prospectively studied 33 AT (post- atrial fibrillation ablation or surgical mitral valve repair).
Left ventricular non-compaction (LV NC) is characterized by abnormal trabeculations that are mainly at the LV apex. Distinction between LV NC and non-specific dilated cardiomyopathies (DCMs) remains often challenging. We sought to find additive tools comparing the longitudinal strain characteristics of LVNC versus idiopathic DCM in a cohort of patients.
