Local Passive Heat for the Treatment of Hypertension in Autonomic Failure

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Supine hypertension affects a majority of patients with autonomic failure; it is associated with end‐organ damage and can worsen daytime orthostatic hypotension by inducing pressure diuresis and volume loss during the night.

Parasympathetic and Sympathetic Monitoring Identifies Earliest Signs of Autonomic Neuropathy

NeuroSci, 2022
The progression of autonomic dysfunction from peripheral autonomic neuropathy (PAN) to cardiovascular autonomic neuropathy, including diabetic autonomic neuropathy and advanced autonomic dysfunction, increases morbidity and mortality risks.

Long COVID and the Autonomic Nervous System: The Journey from Dysautonomia to Therapeutic Neuro-Modulation through the Retrospective Analysis of 152 Patients

NeuroSci, 2022
Introduction. The severity and prevalence of Post-Acute COVID-19 Sequela (PACS) or long-COVID syndrome (long COVID) should not be a surprise. Long-COVID symptoms may be explained by oxidative stress and parasympathetic and sympathetic (P&S) dysfunction ...

Baroreflex Curve Fitting Using a WYSIWYG Boltzmann Sigmoidal Equation

Frontiers in Neuroscience, 2021
Arterial baroreflex assessment using vasoactive substances enables investigators to collect data pairs over a wide range of blood pressures and reflex reactions. These data pairs relate intervals between heartbeats or sympathetic neural activity to blood

Splanchnic Venous Compression Enhances the Effects of ß‐Blockade in the Treatment of Postural Tachycardia Syndrome

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Splanchnic venous pooling induced by upright posture triggers a compensatory increase in heart rate (HR), a response that is exaggerated in patients with postural tachycardia syndrome.

Analytic and Integrative Framework for Understanding Human Sympathetic Arterial Baroreflex Function: Equilibrium Diagram of Arterial Pressure and Plasma Norepinephrine Level

Frontiers in Neuroscience, 2021
BackgroundThe sympathetic arterial baroreflex is a closed-loop feedback system for stabilizing arterial pressure (AP). Identification of unique functions of the closed system in humans is a challenge. Here we propose an analytic and integrative framework

Slow breathing for reducing stress: The effect of extending exhale

Complementary Therapies in Medicine, 2023
Introduction: Slow breathing techniques are commonly used to reduce stress. While it is believed by mind-body practitioners that extending the exhale time relative to inhale increases relaxation, this has not been demonstrated. Methods: We conducted a 12-

Lupus Pneumonitis Therapy Masks Coronavirus (COVID-19)

Case Reports in Rheumatology, 2021
Introduction. Coronavirus pneumonitis can mimic, or present as, lupus pneumonitis. Lupus may cause inflammation of the myocardium. Lupus pneumonitis high-dose steroid therapy may mask coronavirus (COVID-19). Case Study.
