Mechanisms reducing parasympathetic activity in chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

Initial Experience With Endoscopic Ultrasound‐Guided Gallbladder Drainage Using Lumen‐apposing Metal Stents in Extremely Elderly and Frail Patients

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Endoscopic ultrasound‐guided gallbladder drainage (EUS‐GBD) using lumen‐apposing metal stents (LAMS) is a treatment option for acute cholecystitis in high‐risk surgical patients. However, data on extremely elderly and frail patients are limited. We report our initial experience with EUS‐GBD using electrocautery‐enhanced LAMS in this

Lidocaine Spray Versus Viscous Lidocaine Solution Plus Lidocaine Spray in Patients Undergoing Non‐Sedated Esophagogastroduodenoscopy: A Randomized Controlled Trial

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Background Non‐sedated esophagogastroduodenoscopy (EGD) is preferred in patients at risk from sedatives. However, achieving effective pharyngeal anesthesia remains a challenge. This study compared lidocaine spray alone with a combination of lidocaine spray and viscous lidocaine solution.

Quantifying Cardiac, Respiratory, and Low Frequency Components of CSF Motion From fMRI Inflow Effects

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1916-1928, October 2026.
ABSTRACT Purpose Cerebrospinal fluid (CSF) flow oscillations have emerged as a potentially important marker related to brain clearance, but their acquisition often relies on specialized imaging MRI sequences. The purpose of this work was to enable quantitative assessment of CSF flow associated with cardiac, respiratory, and low‐frequency cycles using ...

Respiratory Physiotherapy Techniques in Neonatal Intensive Care Units: A Scoping Review

Physiotherapy Research International, Volume 31, Issue 4, October 2026.
ABSTRACT Background and Purpose Certain physiological characteristics increase the susceptibility of newborns, particularly preterm infants, to pulmonary collapse. In addition, newborns are prone to the accumulation of airway secretions, which, even in small volumes, can compromise respiratory function.

Assessing the Feasibility of Wearable Devices for Physiological Monitoring and Heat Risk Prediction in Outdoor Agricultural Workers

American Journal of Industrial Medicine, Volume 69, Issue 9, Page 722-744, September 2026.
ABSTRACT Background Outdoor agricultural workers experience significant heat exposure, yet few studies have evaluated whether wearable sensors can reliably measure continuous physiological responses in real field conditions. This pilot study examined the feasibility and predictive utility of core temperature, hydration, heart rate, and movement data ...
