Orthostatic and Supine Blood Pressures Are Associated with White Matter Hyperintensities in Parkinson Disease [PDF]

Journal of Movement Disorders, 2013
Background and Purpose: Several reports on the elderly population have suggested that orthostatic hypotension is associated with white matter hyperintensities (WMH); however, little information is available on patients with Parkinson’s disease (PD ...

Effects of transient change in carotid arterial stiffness on arterial baroreflex during mild orthostatic stimulation

Artery Research, 2012
Stiffening of central conduit arteries –areas where the mechanoreceptors are embedded (e.g., ascending aorta and carotid artery) – is considered to be associated with the impaired baroreflex control in response to hypotensive stress.

Effect of Beach-Chair Position on Cerebral Blood Flow in Patients Undergoing Shoulder Surgery—A Preliminary Observational Study

Journal of Neuroanaesthesiology and Critical Care, 2022
Background Hypotension and cerebral hypoperfusion, commonly encountered in beach-chair position under general anesthesia, carry the risk of neurologic complications. There is a paucity of data on monitoring cerebral perfusion.

Management of supine hypertension in patients with neurogenic orthostatic hypotension: Scientific statement of the American Autonomic Society, European Federation of Autonomic Societies, and the European Society of Hypertension

, 2019
Supine hypertension commonly occurs in patients with neurogenic orthostatic hypotension due to autonomic failure. Supine hypertension promotes nocturnal sodium excretion and orthostatic hypotension, thus, interfering with quality of life.

Classical and Delayed Orthostatic Hypotension in Patients With Unexplained Syncope and Severe Orthostatic Intolerance

Frontiers in Cardiovascular Medicine, 2020
Background: Orthostatic hypotension (OH) is a major sign of cardiovascular autonomic failure leading to orthostatic intolerance and syncope. Orthostatic hypotension is traditionally divided into classical OH (cOH) and delayed OH (dOH), but the ...

Hemodynamic response to orthostatic stress immediately after dialysis session in chronic hemodialysis patients

Renal Replacement Therapy, 2018
Orthostatic hypotension is a risk factor for falls among chronic hemodialysis (HD) patients. This study aimed to investigate the hemodynamic response to orthostatic stress immediately after an HD session.

Navigating adverse immunostimulation: A practical guide for clinical researchers

British Journal of Clinical Pharmacology, EarlyView.
Problem Setting As drug development moves towards more complex products, early clinical development programmes are increasingly hampered by unwanted and/or unexpected activation of the immune system (adverse immune stimulation, AIS). Solution At the Centre for Human Drug Research, we have introduced standardized procedures to make AIS manageable, while

Supine hypertension: A state of the art

, 2022
Patients with cardiovascular autonomic failure (AF) may suffer from neurogenic supine hypertension (nSH), defined as systolic blood pressure (SBP) ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg, after 5 min of rest in the supine ...
