Incidence and severity of acute mountain sickness and associated symptoms in children trekking on Xue Mountain, Taiwan
BACKGROUND Acute mountain sickness (AMS) occurs in non-acclimatized people after an acute ascent to an altitude of 2,500 m or higher. The aim of this study was to examine the incidence and severity of AMS and associated symptoms in children. METHODS The prospective observational study included 197 healthy, non-acclimatized 11 and 12-year-old children trekking the round-trip from the trailhead...
متن کاملMRI Evidence: Acute Mountain Sickness Is Not Associated with Cerebral Edema Formation during Simulated High Altitude
Acute mountain sickness (AMS) is a common condition among non-acclimatized individuals ascending to high altitude. However, the underlying mechanisms causing the symptoms of AMS are still unknown. It has been suggested that AMS is a mild form of high-altitude cerebral edema both sharing a common pathophysiological mechanism. We hypothesized that brain swelling and consequently AMS development i...
متن کاملGreater free plasma VEGF and lower soluble VEGF receptor-1 in acute mountain sickness.
Vascular endothelial growth factor (VEGF) is a hypoxia-induced protein that produces vascular permeability, and limited evidence suggests a possible role for VEGF in the pathophysiology of acute mountain sickness (AMS) and/or high-altitude cerebral edema (HACE). Previous studies demonstrated that plasma VEGF alone does not correlate with AMS; however, soluble VEGF receptor (sFlt-1), not account...
متن کاملAcute mountain sickness susceptibility, fitness and hypoxic ventilatory response.
In a party of 17 subjects who travelled together to 4,500 m, hypoxic ventilatory response (HVR) and maximum oxygen consumption (VO2max) were measured before departure. HVR was measured under constant and varying alveolar carbon dioxide tension (PACO2) conditions. VO2max was measured by both standard expired gas collection technique on a treadmill and using the "shuttle run" technique. On arriva...
متن کاملSea-level assessment of dynamic cerebral autoregulation predicts susceptibility to acute mountain sickness at high altitude.
BACKGROUND AND PURPOSE Dynamic cerebral autoregulation is impaired in subjects who develop acute mountain sickness (AMS), a neurological disorder characterized by headache. The present study examined if the normoxic sea-level measurement of dynamic cerebral autoregulation would predict subsequent susceptibility to AMS during rapid ascent to terrestrial high altitude. METHODS A dynamic cerebra...
