Objectives: To investigate how studies determine the sample size when developing radiomics prediction models for binary outcomes, and whether the sample size meets the estimates obtained by using established criteria.
Methods: We identified radiomics studies that were published from 01 January 2023 to 31 December 2023 in seven leading peer-reviewed radiological journals. We reviewed the sample size justification methods, and actual sample size used.
Deep learning model for automatic detection of different types of microaneurysms in diabetic retinopathy.
Eye (Lond)
January 2025
Department of Surgical Sciences, University of Turin, Turin, Italy.
Purpose: This study aims to develop a deep-learning-based software capable of detecting and differentiating microaneurysms (MAs) as hyporeflective or hyperreflective on structural optical coherence tomography (OCT) images in patients with non-proliferative diabetic retinopathy (NPDR).
Methods: A retrospective cohort of 249 patients (498 eyes) diagnosed with NPDR was analysed. Structural OCT scans were obtained using the Heidelberg Spectralis HRA + OCT device.

Intensive Care Unit, Queen Elizabeth II Jubilee Hospital, Coopers Plains, QLD, Australia.
Objective: Knowledge of intensive care unit (ICU) acquired hypernatremia (ICU-AH) has been hampered by the absence of granular data and confounded by variable definitions and inclusion criteria.
Design: Multicentre retrospective cohort study.
Setting: Twelve ICUs in Queensland (QLD), Australia.

Objective: To describe the incidence of bleeding and thrombotic complications in VA-ECMO according to anticoagulation strategy.
Design: This systematic review and meta-analysis included randomised controlled trials (RCTs) and observational studies reporting bleeding and thrombotic complications in VA-ECMO. The incidence of primary outcomes according to anticoagulation drug and monitoring test was described.
