The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia in high‐altitude deer mice (Peromyscus maniculatus)

The Journal of Physiology, EarlyView.
Abstract figure legend The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia has been contentious. Many high‐altitude natives have greater haemoglobin–O2 affinity (lower P50, the O2 pressure at 50% haemoglobin saturation) than their low‐altitude counterparts, but the advantages of this change for aerobic metabolism have often remained

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 ...

CO2 chemoreflex contributions to ventilatory long‐term facilitation

The Journal of Physiology, EarlyView.
Abstract figure legend To determine whether changes in CO2 chemoreflex sensitivity contribute to ventilatory long‐term facilitation (LTF), we tested the hypothesis that hypercapnic acute intermittent hypoxia (AIH) induces ventilatory LTF and enhances peripheral, but not central, chemoreceptor CO2 chemoreflex sensitivity.

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.

Association of Propofol Versus Midazolam Sedation With Successful Pharyngeal Observation During Upper Gastrointestinal Endoscopy: A Retrospective Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Adequate pharyngeal observation during esophagogastroduodenoscopy (EGD) is increasingly recognized as an important component of high‐quality upper gastrointestinal endoscopy. However, visualization may be impaired by gag reflexes and patient movement.
