[Acute mountain sickness].

Anales de medicina interna (Madrid, Spain : 1984), 1991
Acute mountain sickness is a pathologic reaction as a result of bad adaptation to high altitudes (greater than 2.500 meters). The main symptoms are headache, nausea, vomits, and insomnia. When severe it can produce oliguria, retinal hemorrhage, ataxia and sometimes coma. Its etiology is not well known. It is considered that the first producer factor of

A comparison of two methods of heart rate variability assessment at high altitude. [PDF]

, 2016
Heart rate variability (HRV) is a useful index of autonomic function and has been linked to the development of high altitude (HA) related illness. However, its assessment at HA has been undermined by the relative expense and limited portability of ...

Pyrexia in juvenile dogs: a retrospective analysis of diagnosis and clinical features of 115 Australian cases

Australian Veterinary Journal, EarlyView.
Pyrexia is a non‐specific clinical sign associated with many diseases in dogs. This case series examines the final diagnoses, breed distribution and outcomes in dogs aged 18 months or under with pyrexia >24 h duration. Medical record databases of 11 Australian emergency and referral hospitals between 1st January 2020 and 31st January 2025 were searched

Acute mountain sickness

Medical Journal of Indonesia, 2001
Acute mountain sickness, HAPE (high altitude pulmonary edema) and HACE (high altitude cerebral edema) are associated with acute exposure to altitudes greater than 8000 ft. Although usually self limiting, they can be life threatening. We are not yet clear abour the pathophysiological processes in acute mountain sickness.

Self‐Giving and Reflections on Life Extension: How Love Might Shape the Choice of Whether to Live Past a Natural Human Lifespan

Bioethics, EarlyView.
ABSTRACT Drawing upon a deprivationist account of the badness of death, Ingemar Patrick Linden advocates for a hypothetical state called “contingent immortality.” The future Linden champions is one in which every person would be able to live for as long as they would like, save for events like accidents or murder.

Cognitive function and mood at high altitude following acclimatization and use of supplemental oxygen and adaptive servoventilation sleep treatments. [PDF]

, 2019
Impairments in cognitive function, mood, and sleep quality occur following ascent to high altitude. Low oxygen (hypoxia) and poor sleep quality are both linked to impaired cognitive performance, but their independent contributions at high altitude remain

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

Brain Pathology, EarlyView.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...

Physiological Basis of Sex Differences in Human Performance and Exercise‐Associated Pathology

Clinical Endocrinology, EarlyView.
ABSTRACT The presence of sex differences in human physical performance is well‐established and shaped by distinct endocrine, anatomical and physiological mechanisms. Despite sustained advances, our understanding of how inherent biological factors drive variations in exercise capacity and related pathologies is still developing.
