ReviewTraumatic Brain Injury in Select Low- and Middle-Income Countries: A Narrative Review of the Literature.
Low- and middle-income countries (LMICs) experience the majority of traumatic brain injuries (TBIs), yet few studies have examined the epidemiology and management strategies of TBI in LMICs. The objective of this narrative review is to discuss the epidemiology of TBI within LMICs, describe the adherence to Brain Trauma Foundation (BTF) guidelines for the management of severe TBI in LMICs, and document TBI management strategies currently used in LMICs. Articles from January 1, 2009 to September 30, 2021 that included patients with TBI greater than 18 years of age in low-, low middle-, and high middle-income countries were queried in PubMed. ⋯ Within LMICs there are a myriad of approaches to managing TBI with few randomized controlled trials performed within LMICs to evaluate those interventions. More studies are needed in LMICs to establish the effectiveness and appropriateness of BTF guidelines for managing TBI and to help identify methods for managing TBI that are appropriate in low-resource settings. The problem of limited pre- and post-hospital care is a bigger challenge that needs to be considered while addressing management of TBI in LMICs.

Low morbidity and mortality in children with severe traumatic brain injury treated according to the Lund concept: A population-based study.
Previous reports of mortality and morbidity in pediatric severe traumatic brain injury (TBI) vary considerably, with few population-based studies. Mortality rates from 3-33 % and varying morbidity have been reported, most commonly using the Extended Glasgow Outcome Scale (eGOS). The Lund concept is a treatment algorithm for severe TBI aiming at controlling intracranial pressure (ICP) by reducing cerebral perfusion pressure (CPP). ⋯ In both dichotomized and ordinal analyses, CPP <40 mm Hg and ICP >15 were associated with poor outcome, supporting current guidelines. However, high CPP also was associated with increased mortality and morbidity, supporting that elevated CPP might increase cerebral edema. In this study, the Lund concept resulted in low mortality and a favorable outcome in a majority of severe pediatric TBI patients; however, randomized controlled trials are warranted to verify this.

Liberating patients with severe traumatic brain injury (TBI) from mechanical ventilation is often a challenging task. These patients frequently require prolonged ventilation and have persistent alterations in the level and content of consciousness. Questions about their ability to protect their airway are common. ⋯ Current knowledge is insufficient to reliably predict extubation outcomes in TBI, and practices vary substantially across trauma centers. Yet observational studies provide relevant information that must be weighted when considering the decision to attempt extubation in patients with head injury. This review discusses available evidence on liberation from mechanical ventilation in TBI, proposes priorities for future research, and offers practical advice to guide decisions at the bedside.

White Matter Microstructure is Associated with Serum Neuroactive Steroids and Psychological Functioning.
Military service members are at increased risk for mental health issues, and comorbidity with mild traumatic brain injury (mTBI) is common. Largely overlapping symptoms between conditions suggest a shared pathophysiology. The present work investigates the associations among white matter microstructure, psychological functioning, and serum neuroactive steroids that are part of the stress-response system. ⋯ This study provides novel insight into a potential common pathophysiological mechanism of neurosteroid dysregulation underlying the high risk for mental health issues in military service members. Further, comorbidity of PTSD and mTBI may bring the compensatory effects of the brain's stress response to their limit. Future research is needed to investigate whether neurosteroid regulation may be a promising tool for restoring brain health and improving psychological functioning.

Novel application of the Rotterdam CT score in the prediction of intracranial hypertension following severe traumatic brain injury.
Severe traumatic brain injury (TBI) is associated with intracranial hypertension (ICHTN). The Rotterdam CT score (RS) can predict clinical outcomes following TBI, but the relationship between the RS and ICHTN is unknown. The purpose of this study was to investigate clinical and radiological factors that predict ICHTN in patients with severe TBI. ⋯ The RS was predictive of ICHTN in patients with severe TBI, and the diagnostic accuracy of the model was improved with the inclusion of sulcal effacement at the vertex on CT of the head. Patients with a low RS and no sulcal effacement are likely at low risk for the development of ICHTN.
