Impact of under-assisted ventilation on diaphragm function and structure in a porcine model.

Background: Long-term controlled mechanical ventilation (CMV) in intensive care unit (ICU) induces ventilatory-induced-diaphragm-dysfunction (VIDD). The transition from CMV to assisted mechanical ventilation is a challenge that requires clinicians to balance over-assistance and under-assistance. While the effects of over-assistance on the diaphragm are well known, we aimed to assess the impact of under-assistance on diaphragm function and structure in piglet model with pre-existing VIDD (after long-term CMV) or without VIDD (short-term CMV).

Introduction: In clinical, the echocardiogram is the most widely used for diagnosing heart diseases. Different heart diseases are diagnosed based on different views of the echocardiogram images, so efficient echocardiogram view classification can help cardiologists diagnose heart disease rapidly. Echocardiogram view classification is mainly divided into supervised and semi-supervised methods.

Objective: The objective of this scoping review will be to describe existing guidance documents or studies reporting on the conduct of meta-analyses in updated systematic reviews (USRs) or living systematic reviews (LSRs).
Introduction: The rapid increase in the medical literature poses a substantial challenge in keeping systematic reviews up to date. In LSRs, a review is updated with a pre-specified frequency or when some other signalling criterion is triggered.
Primary care in the COVID-19 pandemic and beyond: Lessons from Ontario.

Vice-Chair of Quality and Innovation in the DFCM at U of T; Associate Professor in the Faculty of Medicine and the Institute of Health Policy, Management and Evaluation at U of T; Scientist in the MAP Centre for Urban Health Solutions at St Michael's Hospital; and a staff physician in the DFCM at St Michael's Hospital, Unity Health Toronto.
Objective: To understand the role of primary care in the COVID-19 pandemic to provide insight into its functioning and inform potential reforms.
Composition Of The Committee: The now dissolved Ontario COVID-19 Science Advisory Table (Science Table) was formed in July 2020 to provide decision makers and the public with a synthesis of rapidly evolving evidence related to COVID-19. The Science Table was based at the Dalla Lana School of Public Health at the University of Toronto, and supported by Public Health Ontario.
AI-based hybrid power quality control system for electrical railway using single phase PV-UPQC with Lyapunov optimization.
Sci Rep
January 2025
Wollega University, Nekemte, Ethiopia.
This research paper presents an advanced AI-driven hybrid power quality management system for electrical railways that addresses critical challenges in 25 kV AC traction networks through a novel integration of single-phase PV-UPQC with ANN-Lyapunov control architecture. The system effectively manages voltage unbalance exceeding 2%, high THD, voltage variations of ± 10%, and poor power factor through a dual-approach methodology combining ANN-based reference signal generation with Lyapunov optimization, enabling dynamic parameter tuning and real-time load adaptation. MATLAB/Simulink simulations validate the system's superior performance, demonstrating significant improvements, including voltage unbalance reduction from 1.
