The role of mitochondrial transition pore, and its modulation, in traumatic brain injury and delayed neurodegeneration after TBI

2009

Following severe traumatic brain injury (TBI), a complex interplay of pathomechanism, such as exitotoxicity, oxidative stress, inflammatory events, and mitochondrial dysfunction occurs. This leads to a cascade of neuronal and axonal pathologies, which ultimately lead to axonal failure, neuronal energy metabolic failure, and neuronal death, which in turn determine patient outcome. For mild and moderate TBI, the pathomechanism is similar but much less frequent and ischemic cell death is unusual, except with mass lesions. Involvement of mitochondria in acute post-traumatic neurodegeneration has been extensively studied during the last decade, and there are a number of investigations implicatin…

Neuro-ICU patient disposition

2018

This article revises the recent evidence on ICU admission criteria for acute neurological patients [traumatic brain injury (TBI) patients, postoperative neurosurgical procedures and stroke].The appropriate utilization of ICU beds is essential, but it is complex and a challenge to attain. To date there are no widely accepted international guidelines for managing these acute brain-injured patients (stroke, TBI, postneurosurgery) in the ICU. The criteria for ICU admission after neurological acute injury, high-dependency unit or a specialized neurosurgical ward vary from institution to institution depending on local structures and characteristics of the available resources. Better evidence to s…

Ventilation, oxidative stress and risk of brain injury in preterm newborn

2020

AbstractPreterm infants have an increased risk of cognitive and behavioral deficits and cerebral palsy compared to term born babies. Especially before 32 weeks of gestation, infants may require respiratory support, but at the same time, ventilation is known to induce oxidative stress, increasing the risk of brain injury. Ventilation may cause brain damage through two pathways: localized cerebral inflammatory response and hemodynamic instability. During ventilation, the most important causes of pro-inflammatory cytokine release are oxygen toxicity, barotrauma and volutrauma. The purpose of this review was to analyze the mechanism of ventilation-induced lung injury (VILI) and the relationship…

Anesthesia for Euthanasia Influences mRNA Expression in Healthy Mice and after Traumatic Brain Injury

2014

Tissue sampling for gene expression analysis is usually performed under general anesthesia. Anesthetics are known to modulate hemodynamics, receptor-mediated signaling cascades, and outcome parameters. The present study determined the influence of anesthetic paradigms typically used for euthanization and tissue sampling on cerebral mRNA expression in mice. Naïve mice and animals with acute traumatic brain injury induced by controlled cortical impact (CCI) were randomized to the following euthanasia protocols (n=10-11/group): no anesthesia (NA), 1 min of 4 vol% isoflurane in room air (ISO), 3 min of a combination of 5 mg/kg midazolam, 0.05 mg/kg fentanyl, and 0.5 mg/kg medetomidine intraperi…

Erythropoietin in Traumatic Brain Injury: An Answer Will Come Soon

2015

Traumatic brain injury (TBI) is a major cause of morbidity and mortality in the United States. It is estimated that each year TBIs are associated with 1.1 million emergency department visits, 235,000 hospitalizations, and 50,000 deaths (1). Despite improvements in medical interventions, there are still no neuroprotective agents available to counteract secondary or delayed damage to the traumatically injured human brain or to promote its repair. TBI encompasses heterogeneous etiologic, anatomical, and molecular patterns of injury that exhibit different propensities to cause cerebral damage. Without careful consideration of individual injuries, the results of therapeutic trials remain difficu…

Traumatic brain injury: integrated approaches to improve prevention, clinical care, and research

2017

Executive summary A concerted effort to tackle the global health problem posed by traumatic brain injury (TBI) is long overdue. TBI is a public health challenge of vast, but insufficiently recognised, proportions. Worldwide, more than 50 million people have a TBI each year, and it is estimated that about half the world’s population will have one or more TBIs over their lifetime. TBI is the leading cause of mortality in young adults and a major cause of death and disability across all ages in all countries, with a disproportionate burden of disability and death occurring in low-income and middle-income countries (LMICs). It has been estimated that TBI costs the global economy approximately $…
