RESUMEN

Objective: Shortage of general neurosurgery and specialized neurotrauma care in low resource settings is a critical setback in the national surgical plans of low and middle-income countries (LMIC). Neurotrauma fellowship programs typically exist in high-income countries (HIC), where surgeons who fulfill the requirements for positions regularly stay to practice. Due to this issue, neurosurgery residents and medical students from LMICs do not have regular access to this kind of specialized training and knowledge-hubs. The objective of this paper is to present the results of a recently established neurotrauma fellowship program for neurosurgeons of LMICs in the framework of global neurosurgery collaborations, including the involvement of specialized parallel education for neurosurgery residents and medical students. Methods: The Global Neurotrauma Fellowship (GNTF) program was inaugurated in 2015 by a multi-institutional collaboration between a HIC and an LMIC. The course organizers designed it to be a 12-month program based on adapted neurotrauma international competencies with the academic support of the Barrow Neurological Institute at Phoenix Children's Hospital and Meditech Foundation in Colombia. Since 2018, additional support from the UK, National Institute of Health Research (NIHR) Global Health Research in Neurotrauma Project from the University of Cambridge enhanced the infrastructure of the program, adding a research component in global neurosurgery and system science. Results: Eight fellows from Brazil, Venezuela, Cuba, Pakistan, and Colombia have been trained and certified via the fellowship program. The integration of international competencies and exposure to different systems of care in high-income and low-income environments creates a unique environment for training within a global neurosurgery framework. Additionally, 18 residents (Venezuela, Colombia, Ecuador, Peru, Cuba, Germany, Spain, and the USA), and ten medical students (the United Kingdom, USA, Australia, and Colombia) have also participated in elective rotations of neurotrauma and critical care during the time of the fellowship program, as well as in research projects as part of an established global surgery initiative. Conclusion: We have shown that it is possible to establish a neurotrauma fellowship program in an LMIC based on the structure of HIC formal training programs. Adaptation of the international competencies focusing on neurotrauma care in low resource settings and maintaining international mentoring and academic support will allow the participants to return to practice in their home-based countries.

RESUMEN

Abstract Introduction: With the evolution of diagnostic techniques in traumatic brain injury (TBI), the study of neurological injury has made progress based on the concepts of primary and secondary injury, leading to the era of proteomics to understand the complex molecular events involved in the process. Objectives: This narrative review is intended to discuss the state of the art of the most frequently used biomarkers in TBI, their clinical utility, and the implications for therapeutic decision-making protocols. Materials and methods: In order to fulfill the objective of this paper, a literature review was conducted of the most important databases. Results: Several biomarkers have been studied as prognostic factors in patients with TBI. Learning about their sensitivity and specificity in neurological injury, and its post-trauma evolution over time, has been the goal of various papers in the past few years. Conclusion: Breakthroughs in the study of protein degradation make it necessary to broaden the spectrum and knowledge of new diagnostic methods in TBI. Further studies are needed to define the role of biomarkers and to promote protocols integrating specific values.

Resumen Introducción: Con la evolución de las técnicas diagnósticas en el trauma craneoencefálico, el estudio de la lesión neurológica ha progresado sobre los conceptos de lesión primaria y secundaria, para entrar así en la era de la proteómica y, con ella, entender los complejos eventos moleculares existentes en su proceso. Objetivos: En esta revisión narrativa se pretende presentar el estado actual de los biomarcadores que más se usan en lesión cerebral traumática, su utilidad clínica y las implicaciones en protocolos de decisión terapéutica. Materiales y métodos: Para dar respuesta al objetivo de este trabajo, se realizó una revisión de la literatura en las principales bases de datos. Resultados: Se han estudiado varios biomarcadores como factor pronóstico en pacientes con trauma craneoencefálico. Conocer su sensibilidad y especificidad para la lesión neurológica, así como su evolución en el tiempo tras el traumatismo, ha sido el objetivo de diversos trabajos en los últimos años. Conclusión: El avance en el estudio de los productos de degradación de las proteínas hace necesario ampliar el espectro y el conocimiento en el campo de los nuevos métodos diagnósticos en el trauma craneoencefálico. Se requieren más estudios para definir la función de los biomarcadores y proponer protocolos que integren valores específicos.

RESUMEN

Background Traumatic brain injury (TBI) is a global public health problem. In Colombia, it is estimated that 70% of deaths from violence and 90% of deaths from road traffic accidents are TBI related. In the year 2014, the Ministry of Health of Colombia funded the development of a clinical practice guideline (CPG) for the diagnosis and treatment of adult patients with severe TBI. A critical barrier to the widespread implementation was identified-that is, the lack of a specific protocol that spans various levels of resources and complexity across the four treatment phases. The objective of this article is to present the process and recommendations for the management of patients with TBI in various resource environments, across the treatment phases of prehospital care, emergency department (ED), surgery, and intensive care unit. Methods Using the Delphi methodology, a consensus of 20 experts in emergency medicine, neurosurgery, prehospital care, and intensive care nationwide developed recommendations based on 13 questions for the management of patients with TBI in Colombia. Discussion It is estimated that 80% of the global population live in developing economies where access to resources required for optimum treatment is limited. There is limitation for applications of CPGs recommendations in areas where there is low availability or absence of resources for integral care. Development of mixed methods consensus, including evidence review and expertise points of good clinical practices can fill gaps in application of CPGs. BOOTStraP (Beyond One Option for Treatment of Traumatic Brain Injury: A Stratified Protocol) is intended to be a practical handbook for care providers to use to treat TBI patients with whatever resources are available. Results Stratification of recommendations for interventions according to the availability of the resources on different stages of integral care is a proposed method for filling gaps in actual evidence, to organize a better strategy for interventions in different real-life scenarios. We develop 10 algorithms of management for building TBI protocols based on expert consensus to articulate treatment options in prehospital care, EDs, neurological surgery, and intensive care, independent of the level of availability of resources for care.
