Although self-report pain ratings are the gold standard in clinical pain assessment, they are inherently subjective in nature and significantly influenced by multidimensional contextual variables. Although objective biomarkers for pain could substantially aid pain diagnosis and development of novel therapies, reliable markers for clinical pain have been elusive. In this study, individualized physical maneuvers were used to exacerbate clinical pain in patients with chronic low back pain (N = 53), thereby experimentally producing lower and higher pain states.

Lower resting heart rate and high autonomic vagal activity are strongly associated with superior exercise capacity, maintenance of which is essential for general well-being and healthy aging. Recent evidence obtained in experimental studies using the latest advances in molecular neuroscience, combined with human exercise physiology, physiological modeling, and genomic data suggest that the strength of cardiac vagal activity causally determines our ability to exercise.

The prevalence of diabetes is steadily rising, and once it occurs, it can cause multiple complications with a negative impact on the whole organism. Complications of diabetes may be macrovascular: such as stroke and ischemic heart disease as well as peripheral vascular and microvascular diseases-retinopathy, nephropathy, and neuropathy. Key factors that cause cardiovascular disease in people with diabetes include hyperglycemia, dyslipidemia, obesity, insulin resistance, inflammation, hypertension, autonomic dysfunction, and decreased vascular response capacity.

Background: Although in-lab polysomnography (PSG) remains the gold standard for objective sleep monitoring, the use of at-home sensor systems has gained popularity in recent years. Two categories of monitoring, autonomic and limb movement physiology, are increasingly recognized as critical for sleep disorder phenotyping, yet at-home options remain limited outside of research protocols. The purpose of this study was to validate the BiostampRC sensor system for respiration, electrocardiography (ECG), and leg electromyography (EMG) against gold standard PSG recordings. Read More

BACKGROUND Obesity is one of the leading causes of morbidity and mortality globally and challenging to treat because of the multifactorial etiology and presentation. Individualized homeopathy takes into account factors that led to a patient's health condition and hence may have a role in the treatment of obesity and related co-morbidities; co-morbidities that may arising from the same etiology may respond as a whole to homeopathy treatment. CASE REPORT A 39-year-old Russian female who developed multiple problems after severe emotional stress was treated with individualized classical homeopathic therapy. Read More

During pregnancy, incessant tachyarrhythmias may result in hemodynamic compromise in both the expectant mother and the fetus. The use of antiarrhythmic drugs is typically not safe during pregnancy, and some tachycardias are refractory to pharmacologic treatment due to a significant autonomic imbalance. Catheter ablation is thought to be more effective than medical therapy, but carries the risk of radiation exposure to the fetus. Read More

Posttraumatic stress disorder (PTSD) is characterized by increased sympathetic nervous system (SNS) activity, blunted parasympathetic nervous system (PNS) activity, and impaired baroreflex sensitivity (BRS), which contribute to accelerated cardiovascular disease. Patients with PTSD also have chronic stress-related elevations in resting blood pressure (BP), often in the prehypertensive range; yet, it is unclear if elevated resting blood pressure (ERBP) augments these autonomic derangements in PTSD. We hypothesized that compared with normotensive PTSD (N-PTSD), those with ERBP (E-PTSD) have further increased SNS, decreased PNS activity, and impaired BRS at rest and exaggerated SNS reactivity, PNS withdrawal, and pressor responses during stress.

The prevalence of diabetes is rapidly increasing and closely associated with cardiovascular morbidity and mortality. While the major cardiovascular complication associated with diabetes is coronary artery disease, it is becoming increasingly apparent that diabetes impacts the electrical conduction system in the heart, resulting in atrial fibrillation, and ventricular arrhythmias. The relationship between diabetes and arrhythmias is complex and multifactorial including autonomic dysfunction, atrial and ventricular remodeling and molecular alterations. Read More

Primary afferent neurons transduce distension of the bladder wall into action potentials that are relayed into the spinal cord and brain, where autonomic reflexes necessary for maintaining continence are coordinated with pathways involved in sensation. However, the relationship between spinal circuits involved with physiological and nociceptive signalling from the bladder have only been partially characterised. We used ex-vivo bladder afferent recordings to characterise mechanosensitive afferent responses to graded distension (0-60mmHg) and retrograde tracing from the bladder wall to identify central axon projections within the dorsal horn of the lumbosacral spinal cord.

We examined the hypothesis that delayed heart rate recovery (HRR) after exercise testing, an estimate of decreased autonomic function, predicts the risk of cardiometabolic syndrome (MetS) and is associated with continuous MetS risk scores in healthy men. Participants were 2,740 men who underwent general health examinations and had no evidence of MetS, cardiovascular diseases, diabetes, and hypertension at baseline. Baseline HRR was calculated as the difference between peak heart rate attained during exercise testing and the heart rate at 1 (HRR 1) and 2 minutes (HRR 2) after test termination. Read More

Objectives: The ability to produce situation-appropriate cognitive and emotional responses is dependent on autonomic nervous system (ANS) functionality. Heart rate variability (HRV) is an index of ANS functionality, and resting HRV levels have been associated with cognitive control and inhibitory capacity in young adults, particularly when faced with emotional information. As older adults' greater preference for positive and avoidance of negative stimuli (positivity effect) is thought to be dependent on cognitive control, we hypothesized that HRV could predict positivity-effect magnitude in older adults.

Purpose: The in vivo diagnosis of synucleinopathies is an important research aim since clinical diagnostic criteria show low accuracy. The skin innervation, especially the autonomic subdivision, is a useful region to search for abnormal α-syn aggregates in synucleinopathies since the peripheral sympathetic nerves can be the earliest-affected neural region and autonomic symptoms may precede the classical symptoms of these disorders.
Methods: The major advantages of skin biopsy as an in vivo diagnostic tool for synucleinopathies are that it is an inexpensive and easy-to-perform technique requiring only limited facilities, and that it is repeatable in long-term studies as it causes only minor discomfort to the patient. Read More
