Abstract: This is a special case report on Jamaica's first use of hyperbaric oxygen therapy (HBOT) in stroke recovery, presented at the 56th Annual Conference of the Association of Surgeons in Jamaica, Kingston, Jamaica. The literature and story behind the trial ‒...
Stroke
Nrf2/antioxidant defense pathway is involved in the neuroprotective effects of Sirt1 against focal cerebral ischemia in rats after hyperbaric oxygen preconditioning.
Abstract: Sirtuin 1 (Sirt1) is a class III histone deacetylase involved in neuroprotection induced by hyperbaric oxygen preconditioning (HBO-PC) in animal models of ischemia. However, the underlying mechanisms remain to be illustrated. In the present study, rats...
Systemic air embolism causing acute stroke and myocardial infarction after percutaneous transthoracic lung biopsy – a case report.
Abstract: The air embolism in this case was likely to have been caused by positioning the patient in a prone position, which was associated with the lesion to be biopsied being at a maximum height over the left atrium. Due to the resulting negative pressure, air...
MRI of brain tissue oxygen tension under hyperbaric conditions.
Abstract: The brain depends on a continuous supply of oxygen to maintain its structural and functional integrity. This study measured T1 from MRI under normobaric air, normobaric oxygen, hyperbaric air, and hyperbaric oxygen (HBO) conditions as a marker of tissue pO2...
Effects of Normobaric Hyperoxia in Severe Acute Stroke: a Randomized Controlled Clinical Trial Study.
Abstract: Oxygen therapy might increase damaged tissue oxygenation, turn on the aerobic pathway, and save neurons from death and could improve clinical outcome of the patients with stroke and head trauma. Hyperbaric oxygen therapy is accompanied by some unfavorable...
Treatment with Isorhamnetin Protects the Brain Against Ischemic Injury in Mice.
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...
Hyperbaric Oxygen Preconditioning Attenuates Hemorrhagic Transformation Through Reactive Oxygen Species/Thioredoxin-Interacting Protein/Nod-Like Receptor Protein 3 Pathway in Hyperglycemic Middle Cerebral Artery Occlusion Rats.
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...
Clinical Trial – HBOT Global Functioning After Stroke
Stroke is one of the leading causes of disability and death in North America and Europe. Up
to 30% of stroke survivors never recuperate completely and suffer from loss of function and
poor quality of life. To improve recovery after stroke, innovative interventions should be a
priority.
Hyperbaric oxygen therapy (HBOT) is an intermittent inhalation of 100% oxygen in a hyperbaric
chamber at a pressure higher than 1 absolute atmosphere (ATA). There is a growing body of
evidence that HBOT can enhance ability of brain to changes its structure (neuroplasticity) in
order to recover. Exercise program during HBOT can augment the effect. Although, recent
randomized controlled trials in patients with chronic brain injury showed promising results,
there are no studies demonstrating combine effect HBOT and exercise rehabilitation program on
stroke recovery.
The proposed study investigates feasibility, safety and efficacy of using a combination of
HBOT and exercise program to improve arm function recovery in chronic stroke patients. In
this pilot randomized control trial, investigators will compare the combination of HBOT and
the focused rehabilitation exercise program versus exercise program alone on recovery of arm
function in patients with chronic stroke.
Sensorineural deafness following routine transurethral resection of the prostate.
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...
The Efficacy of Hyperbaric Oxygen Therapy on Middle Cerebral Artery Occlusion in Animal Studies: A Meta-Analysis.
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...
