Orthostatic intolerance in chronic fatigue syndrome

Journal of Translational Medicine, 2019
Background Orthostatic intolerance (OI) is a significant problem for those with chronic fatigue syndrome (CFS). We aimed to characterize orthostatic intolerance in CFS and to study the effects of exercise on OI.

CHARGE Syndrome: A Narrative Review and Update on Diagnosis, Assessment and Management

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background CHARGE syndrome (CS) is a rare multisystemic genetic condition caused by a pathogenic variant in the DNA‐binding protein‐7 CHD7 gene. The condition affects the development of neural crest cells, which give rise to craniofacial structures, cranial nerves, ears, eyes and the heart, resulting in diverse and complex clinical features ...

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 ...

Tilt Table Testing in Paediatric Orthostatic Intolerance: Is 10 Min Long Enough?

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Aim Recent cardiovascular literature suggests that orthostatic testing protocols should be tailored according to diagnostic purpose, distinguishing syncope evaluation from assessment of autonomic dysfunction in chronic orthostatic intolerance (COI).

Clinical Symptomatology, Cognition and Psychosocial Wellbeing in Adolescents With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Cross‐Sectional Observational Study

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Aim Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling illness that frequently begins in adolescence, yet adolescents with ME/CFS remain an under‐researched population. We aimed to characterise the cognitive and psychosocial wellbeing of adolescents with ME/CFS relative to normative benchmarks and unaffected age‐peers ...

Internal Jugular Vein as an Alternative Access for Pacemaker Implantation: A Mostly Left IJ Case Series

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Leadless pacemakers traditionally rely on femoral venous access, which may be limited in patients with unfavorable IVC anatomy, prior interventions, or situations where preserving femoral access is preferred. Internal jugular (IJ) access offers an alternative route, but real‐world data on IJ implantation of single‐ and dual‐chamber ...

Orthostatic intolerance and presyncopal states in young adults

Journal of Education, Health and Sport
Introduction and purpose: Orthostatic intolerance is an increasingly recognized disturbance of circulatory regulation in young adults, particularly in academic settings where characteristic lifestyle patterns promote autonomic imbalance. The aim of this

Individuals with persisting post‐concussion symptoms with physiological subtype demonstrate altered cardiovascular and autonomic responses to face cooling

Experimental Physiology, EarlyView.
Abstract Individuals with persisting post‐concussion symptoms with physiological subtype (PPCS‐P) demonstrate exercise intolerance due to exacerbation of concussion‐like symptoms during incremental exercise. We tested the hypothesis that individuals with PPCS‐P (n = 12) would have a blunted cardiac autonomic response to face cooling compared to healthy

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.

No evidence of higher peak heat tolerance in the afternoon or with opportunity for thermal behaviour during low‐intensity work in uncompensable heat

Experimental Physiology, EarlyView.
Abstract Heat tolerance is known to be limited by high brain temperature, but most findings pertain to strenuous exercise following artificially altered baseline temperature or with limited opportunity for behaviour. Therefore, we investigated the hypotheses that thermal perceptions, hyperventilation and cerebrovascular responses would be exacerbated ...
