Background: The development and testing of a deep learning (DL)-based approach for detection and measurement of regions of (EZ) to study progression in nonexudative age-related macular degeneration (AMD).
Methods: Used in DL model training and testing were 341 subjects with nonexudative AMD with or without geographic atrophy (GA). An independent dataset of 120 subjects were used for testing model performance for prediction of GA progression.
The current study describes the development and assessment of innovative, machine learning (ML)-based approaches for automated detection and pixel-accurate measurements of regions with geographic atrophy (GA) in late-stage age-related macular degeneration (AMD) using optical coherence tomography systems. 900 OCT volumes, 100266 B-scans, and OCT images from 341 non-exudative AMD patients with or without GA were included in this study from both Cirrus (Zeiss) and Spectralis (Heidelberg) OCT systems. B-scan and level ground truth GA masks were created on OCT B-scan where the segmented ellipsoid zone (EZ) line, retinal pigment epithelium (RPE) line, and bruchs membrane (BM) line overlapped.

Aims: The aim of the study is to increase the perfusion ratio between local and systemic compartments on isolated pelvic perfusion.
The results of four prospective clinical trials testing intraperitoneal chemohyperthermia (IPCH) are reported. The first one aimed at determining the appropriate dose of heated (42 degrees C) intraperitoneal oxaliplatin following complete resection of peritoneal carcinomatosis (PC) by studying its pharmacokinetics. The recommended dosage was set at 460 mg/m2 in 2 l/m2 of peritoneal instillation.
