Ventilatory and cerebrovascular responses to exercise in lowlander children acclimatizing to high‐altitude

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Astrocytes: Orchestrators of brain gas exchange and oxygen homeostasis

The Journal of Physiology, EarlyView.
Abstract figure legend Oxygen and carbon dioxide enter the body via breathing; in the brain astrocytes play a key role balancing oxygen delivery with carbon dioxide removal. Abstract If we consider neurons like muscles during exercise, the demand for oxygen (O2) and carbon dioxide (CO2) elimination is constantly changing.

How breathing disrupts vision: hyperventilation‐induced hypocapnia impairs oculomotor responses in resting humans

The Journal of Physiology, EarlyView.
Abstract figure legend Hypocapnic hyperventilation reduced end‐tidal carbon dioxide partial pressure and middle cerebral artery mean velocity, and impaired oculomotor response by modulating visual fixation and anti‐saccadic control. Hyperventilation itself also impaired anti‐saccadic control.

Comparison effectiveness of topical analgesics with and without Entonox for esophagogastroduodenoscopy: A randomized controlled trial

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives Esophagogastroduodenoscopy (EGD) is vital for diagnosing and treating upper gastrointestinal symptoms, but patient discomfort and anxiety can affect procedural outcomes. This study aimed to compare the effectiveness of topical analgesics with and without Entonox during EGD in terms of procedural success, patient tolerance, and ...

Acute Exercise Challenge and Airway Dynamics in Youth With Sickle Cell Anemia: A Multicenter Study

American Journal of Hematology, Volume 101, Issue 3, Page 418-426, March 2026.
Changes in airway dynamics in children with sickle cell anemia after maximal cardiopulmonary exercise testing and a controlled intensity interval excercise challenge. ABSTRACT Sickle cell anemia (SCA) leads to reduced physical functioning and cardiopulmonary fitness. Prior studies suggest that airway hyperresponsiveness to bronchoprovocation testing is
