Orthostatic intolerance after space flight [PDF]

The Journal of Physiology, 2002
Physiologists have always been challenged by the adjustments of the human body to hostile environments. The set of papers in this issue of The Journal of Physiology (Cox et al. 2002; Ertl et al. 2002; Levine et al. 2002) fits into the tradition of the study of human responses to extreme physical circumstances.

Common Syndromes of Orthostatic Intolerance [PDF]

Pediatrics, 2013
The autonomic nervous system, adequate blood volume, and intact skeletal and respiratory muscle pumps are essential components for rapid cardiovascular adjustments to upright posture (orthostasis). Patients lacking sufficient blood volume or having defective sympathetic adrenergic vasoconstriction develop orthostatic hypotension (OH), prohibiting ...

Impaired Cerebral Autoregulation during Head Up Tilt in Patients with Severe Brain Injury. [PDF]

PLoS ONE, 2016
Early mobilization is of importance for improving long-term outcome for patients after severe acquired brain injury. A limiting factor for early mobilization by head-up tilt is orthostatic intolerance.

Neurocirculatory Abnormalities in Chronic Orthostatic Intolerance [PDF]

Circulation, 2005
Background— Chronic orthostatic intolerance (COI) occurs in postural tachycardia syndrome (POTS) and in some individuals with repeated neurocardiogenic syncope/presyncope (NCS), without POTS. This study addressed whether patients with COI and POTS or NCS have neurocirculatory abnormalities during ...

Delayed symptoms and orthostatic intolerance following peanut challenge

Clinical and Experimental Allergy, 2021
Clinical reactions to Oral Food Challenge (OFC) in peanut‐allergic individuals have been well‐characterised, but rates and phenotypes of symptom recurrence beyond the first hour after objective symptoms are less well‐characterised.
