In children with biliary atresia (BA), breath‐holding during liver and spleen stiffness (LS and SS) measurement is often difficult, raising concerns about measurement reliability in the awake state. We investigated whether performing LS and SS measurements under general anesthesia—when brief ventilation pauses are possible—could improve diagnostic ...

ABSTRACT Aim This study aims to examine the effects of lateral positions during the second stage of labour on maternal and neonatal outcomes. Design A prospective observational study was conducted in three Chinese hospitals from June to November 2020. Methods Eligible women were divided into groups based on their use of lithotomy or lateral positions ...

ABSTRACT Home sleep apnea tests (HSATs) have emerged as alternatives to in‐laboratory polysomnography (PSG), but Type IV HSATs often show limited diagnostic performance. This study clinically validates SleepAI, a novel remote digital health system that applies AI algorithms to raw oximetry data for automated sleep staging and obstructive sleep apnea ...

ABSTRACT Low‐load blood flow restriction training (LLBFRT) induces significant vascular stress, which is often associated with vascular remodeling, increased capillarization and muscle blood flow. These adaptations may be of interest to climbers as their endurance performance is limited by blood supply due to the isometric and intermittent nature of ...

Abstract Heart failure (HF) with a mildly reduced ejection fraction (HFmrEF; 40%–49%) is present in ≤25% of HF patients. Therapeutic treatment options for HFmrEF‐associated exercise intolerance are limited. Nitric oxide (NO)‐independent stimulation of soluble guanylyl cyclase to improve peripheral vasodilatation offers a novel approach to enhance ...

Microelectrode recordings from the human cervical vagus nerve during maximal breath‐holds
Abstract Voluntary breath‐holds can be sustained for a long time following training, but ultimately, regardless of duration, the asphyxic break‐point is reached and the apnoea terminated. The physiological changes occurring during the apnoea include a marked increase in sympathetically‐mediated vasoconstriction in non‐essential organs, such as skeletal

Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...

Abstract This study was motivated by the limited high‐altitude physiology data available for Asian military aviators, especially in Vietnam. To characterize acute heart rate (HR), blood pressure (BP), and oxygen saturation (SpO2) responses in healthy Vietnamese pilots during simulated 5000 m hypobaric exposure. Seventy‐five healthy male military pilots
