Hyperbaric Oxygen Therapy (HBOT) Research for Stroke
Abstract: Ischemic stroke is a major cause of morbidity and mortality, yet lacks effective neuroprotective treatments. The aim of this work was to investigate whether treatment with isorhamnetin protected the brain against ischemic injury in mice. Experimental stroke...
Abstract: To clarify whether hyperbaric oxygen preconditioning can attenuate hyperglycemia-enhanced hemorrhagic transformation and to establish a role for Nod-like receptor protein 3 inflammasome in the pathophysiology of hemorrhagic transformation. Controlled...
Abstract: A man in his 50s presented to a rural Australian emergency department with complete unilateral hearing loss following transurethral resection of the prostate. His hearing impairment progressed from 'muffled hearing' with tinnitus on emergence from...
Abstract: Inconsistent results have been reported for hyperbaric oxygen therapy (HBO) for acute stroke. We conducted a systematic review and meta-analysis to evaluate the benefit of HBO in animal studies of middle cerebral artery occlusion (MCAO). A systematic search...
Abstract: Water covers over 70% of the earth, has varying depths and temperatures and contains much of the earth's resources. Head-out water immersion (HOWI) or submersion at various depths (diving) in water of thermoneutral (TN) temperature elicits profound...
Abstract: Cognitive impairment may occur in 42-50% of cardiac arrest survivors. Hyperbaric oxygen therapy (HBO2) has recently been shown to have neurotherapeutic effects in patients suffering from chronic cognitive impairments (CCI) consequent to stroke and mild...
The current debate surrounding the use of hyperbaric oxygen (HBO2) for neurological indications, specifically mild to moderate chronic traumatic brain injury (mTBI) and post-concussion syndrome (PCS), is mired in confusion due to the use of non-validated controls and an unfamiliarity by many practitioners of HBO2 therapy with the experimental literature. In the past 40 years, the use of an air sham (21% oxygen, 1.14-1.5 atmospheres absolute/atm abs) in clinical and animal studies, instead of observational or crossover controls, has led to false acceptance of the null hypothesis (declaring no effect when one is present), due to the biological activity of these “sham” controls. The recent Department of Defense/Veterans Administration (DoD/VA) sponsored trials, previous published reports on the use of HBO2 therapy on stroke and mTBI and preliminary reports from the HOPPS Army trial, have helped to highlight the biological activity of pressurized air, validate the development of a convincing control for future studies and demonstrate the effectiveness of a hyperbaric intervention for mTBI/ PCS. Approval of HBO2 for neurological indications, especially for mTBI/PCS, should be granted at the federal, state and certifying body levels as a safe and viable treatment for recovery in the post-acute phase.
Abstract: The goals of phase II clinical trials are to gain important information about the performance of novel treatments and decide whether to conduct a larger phase III trial. This can be complicated in cases when the phase II trial objective is to identify a...
Abstract: Traumatic brain injury (TBI) is a growing health concern affecting civilians and military personnel. In this review, treatments for the chronic TBI patient are discussed, including pharmaceuticals, nutraceuticals, cognitive therapy, and hyperbaric oxygen...
