Active clinical trials for "Altitude Sickness"

Randomized, placebo controlled trial evaluating the effect of acetazolamide on visuo-motor learning performance in lowlanders older than 40 years travelling from 760 m to 3'100 m.

The study will aim to describe and evaluate the effect of chronic beetroot juice supplementation on acute mountain sickness symptoms and exercise in a hypoxic environment. It is hypothesized that beetroot supplementation will decrease acute mountain sickness and increase exercise performance.

Prospective interventional trial in lowlanders evaluating the effect of acute exposure, acclimatization and re-exposure of high altitude on nocturnal breathing pattern.

Prospective interventional trial in lowlanders evaluating the effect of acute exposure, acclimatization and re-exposure to high altitude on postural control

prospective controlled interventional trial evaluating the efficacy of a 3-weeks asthma rehabilitation program at high altitude (3200m) and low altitude (760m) on lung function and asthma control.

To determine if a prolonged high altitude simulation test (HAST) lasting two hours, identifies more patients at risk of respiratory failure than the standard HAST lasting 20 minutes, in patients with neuromuscular disease (NMD) and severe pulmonary restriction. To evaluate the safety of supplemental oxygen administered in those with a positive HAST in the NMD population.

This study is designed to be the first to examine the novel drug budesonide for prevention of acute mountain sickness in comparison to acetazolamide and in the context of rapid ascent to high altitude. The investigators will accomplish these objectives with a prospective, double blinded view of a large population of hikers who are ascending at their own rate in a true hiking environment.

Traditional folk medicine in the Arctic and Himalayan areas used Rhodiola species to enhance physical endurance, prevent aging, resist acute mountain sickness (AMS), and to treat fatigue, depression, anemia, impotence and respiratory infections. Rhodiola crenulata are widely used to prevent AMS in Himalayan areas and Lhasa in Tibet but none was examined by human study. The investigators conducted a randomized, double blind, placebo controlled, crossover study to investigate the efficacy of Rhodiola crenulata in preventing AMS.

Acclimatization by mountaineering prior to high altitude sojourns have shown to be effective in prevention of acute mountain sickness (AMS). The aim of this study is to investigate whether intermittent exposure to normobaric hypoxia during sleep is also effective to prevent AMS.

Life expectancy and quality of human life are important indicator of the sustainable development of the society. At the same time, the physical, functional, emotional and psychological components of the of the quality of life evaluation are subjected to be evaluated objectively and corrected using modern medical and socio-psychological methods. According to a fair number of experts, the arsenal of means for functional rehabilitation and health promotion is limited, and its expansion is only possible on the basis of the principles of adaptation medicine and their translation from experimental research into specific preventive and health-promoting technologies. The study is aimed at the development in molecular-endocrine, neuro-visceral and psychophysiological complex mechanisms of human long-term adaptation to systemic modern heating device-based hyperthermia for the development of medical technology focused on optimization in physical functioning, neuro-autonomic regulation, psycho-emotional status and stress- resistance as objective characteristics of humans' quality of life in working age. The novelty of the project is the disclosure of key mechanisms of adaptational direct and cross-effects to the prolonged systemic individually dosed hyperthermia underlying the optimization of stress-resistance, psycho-physiological status and exercise tolerance of practically healthy persons and leading to an increase in the subjectively perceived quality of life. The discovery of the mechanisms of hyperthermically induced neuroplasticity (in terms of the dynamics of oxidative stress, heat shock proteins and the brain derived neurotrophic factor) will also have a scientific significance, which in the long term prospectives may play a role in the development of technics for the prevention and rehabilitation of age-associated neuro-degenerative processes and diseases.
