Article Abstract
This review highlights the latest advancements in imaging techniques for monitoring respiratory muscles in critically ill patients. At the bedside, conventional ultrasound has been widely adopted to measure diaphragm thickness, thickening and excursion. It has also been used to assess extradiaphragmatic respiratory muscles, including parasternal intercostal and abdominal muscles. Advanced ultrasound-derived techniques have expanded its applications, enabling the evaluation of tissue velocity (tissue Doppler imaging), stiffness (shear wave elastography), and local tissue displacement (speckle tracking). Facility-based imaging modalities such as magnetic resonance imaging and chest tomography provide complementary insights into respiratory muscles structure and function, offering valuable information for evaluating the effects of therapeutic interventions. Finally, imaging techniques have emerged as valuable tools for evaluating the metabolic demands of respiratory muscles, with advanced methods such as positron emission tomography and contrast-enhanced ultrasound showing significant potential.

Idiopathic Premature Ventricular Complexes Originating From Right Ventricular False Tendons.

Department of Cardiology, Second Affiliated Hospital of Third Military Medical University (Army Medical University), Chongqing, China.
Background And Aims: Ablation for premature ventricular complexes (PVCs) originating from the right ventricular inflow tract (RVIT) is challenging. Few studies have identified the correlation between right ventricular false tendons (RVFTs) and RVIT PVCs. This study aimed to verify RVFTs as arrhythmogenic and electro-anatomical substrates for PVCs, and propose an enlightening mapping and ablation protocol to improve operative efficacy.

Background: Neural respiratory drive (NRD) is a clinically relevant biomarker in patients with chronic obstructive pulmonary disease (COPD). However, its analysis is challenging due to several technical considerations, including the need to obtain a stable recording over a short time period. However, a short recording duration may be inadequate to comprehensively record clinically relevant information, particularly during sleep, because NRD varies across sleep stages and over time.

Purpose: This study aimed to investigate muscle atrophy in critically ill patients using ultrasonography. We compared the rectus femoris (a major muscle of the lower limbs) with the sternocleidomastoid (an accessory respiratory muscle).
Methods: Thirty-four patients hospitalized at the Critical Care Medical Center of Kindai University Hospital between January 2022 and March 2023 were enrolled.
Elucidating the role of human skeletal muscles in the pathogenesis of enterovirus D68 infection.

Enterovirus D68 (EV-D68) is an emerging respiratory virus associated with extra-respiratory complications, especially acute flaccid myelitis. However, the pathogenesis of acute flaccid myelitis is not fully understood. It is hypothesised that through infection of skeletal muscles, the virus further infects motor neurons via the neuromuscular junction.

Muscle metaboreflex is activated in limb skeletal muscles during high-intensity exercise that increases respiratory demand, but its effects on respiratory muscle blood flow remain unknown. Therefore, we investigated whether metaboreflex activation in the forearm alters blood flow in the intercostal muscles. Sixteen healthy young male subjects performed isometric handgrip at 30% of maximal voluntary contraction for 2 minutes, followed by either post-exercise muscle ischemia (PEMI; metaboreflex activation condition) or a control recovery.
