A NOVEL TRANSFORMER-BASED SELF-SUPERVISED LEARNING METHOD TO ENHANCE PHOTOPLETHYSMOGRAM SIGNAL ARTIFACT DETECTION

A Novel Transformer-Based Self-Supervised Learning Method to Enhance Photoplethysmogram Signal Artifact Detection

Recent research has revealed that traditional machine learning methods, such as semi-supervised label propagation and K-nearest neighbors, outperform Transformer-based IV and Instrument Stands models in artifact detection from photoplethysmogram (PPG) signals, mainly when data is limited.This study addresses the underutilization of abundant unlabel

An unhealthy holiday on Lake Bolsena

A 70-year old man (OL) was hospitalized due to Dosing Funnel fever (up to 40°C) associated with malaise and abdominal pain.Tests showed hypereosinophilic syndrome, and increased liver and inflammation indexes.Abdominal echography showed a nonhomogeneous liver and the spleen was enlarged.Abdominal computed tomography showed multiple abscesses on th
