Perioperative Changes in Blood Volume and Fluid Distribution in Total Hip Arthroplasty—A Protocol for a Prospective Single‐Center Observational Study

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 8, September 2026.
ABSTRACT Background Surgical stress response initiates a complex pathophysiological cascade that alters fluid distribution and intravascular volume. In elective total hip arthroplasty (THA), the perioperative blood loss is potentially substantial, a significant part of the loss being hidden caused by tissue extravasation, residual joint blood, and ...

Epidural Spinal Cord Stimulation of Lumbosacral Networks Modulates Arterial Blood Pressure in Individuals With Spinal Cord Injury-Induced Cardiovascular Deficits

Frontiers in Physiology, 2018
Disruption of motor and autonomic pathways induced by spinal cord injury (SCI) often leads to persistent low arterial blood pressure and orthostatic intolerance.

Meta‐Analysis: Chronic Gastrointestinal Symptoms and Comorbidities in Hypermobile Ehlers–Danlos Syndrome and Hypermobility Spectrum Disorders

Alimentary Pharmacology &Therapeutics, Volume 64, Issue 5, Page 574-589, September 2026.
This meta‐analysis reveals that a significant proportion of patients with hEDS/HSD experience gastrointestinal symptoms. The most prevalent symptoms include heartburn, abdominal pain, constipation, and nausea. There is a notable overlap of hEDS/HSD with chronic fatigue, DGBI, GERD, migraine, and orthostatic intolerance.

Frequency and characteristics of multi‐domain autonomic dysfunction in patients with spontaneous intracranial hypotension

Headache: The Journal of Head and Face Pain, Volume 66, Issue 8, Page 1890-1897, September 2026.
Plain Language Summary Spontaneous intracranial hypotension (SIH) is caused by leakage of cerebrospinal fluid and often produces symptoms that worsen when standing, which may resemble autonomic disorders (conditions related to blood flow and heart rate).

Risk of Orthostatic Intolerance During Re-Exposure to Gravity [PDF]

, 2015
Post-spaceflight orthostatic intolerance remains a significant concern to NASA. In Space Shuttle missions, astronauts wore anti-gravity suits and liquid cooling garments to protect against orthostatic intolerance during re-entry and landing, but in ...

Neuropathy in Val122Ile Hereditary Transthyretin (ATTR) Amyloidosis: A Multicenter Retrospective Cohort Study

Journal of the Peripheral Nervous System, Volume 31, Issue 3, September 2026.
ABSTRACT Background and Aims The Val122Ile ATTR Amyloidosis has traditionally been linked to cardiac manifestations. Recent studies suggest that neuropathy may be relevant. In this study, we characterized its peripheral nerve manifestations in depth. Methods This was a national, multicenter, observational, retrospective study.
