USEFULNESS OF ARTIFICIAL INTELLIGENCE IN TRAUMATIC BRAIN INJURY: A BIBLIOMETRIC ANALYSIS AND MINIREVIEW. World Neurosurg 2024:S1878-8750(24)00828-3. [PMID: 38759786 DOI: 10.1016/j.wneu.2024.05.065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Accepted: 05/10/2024] [Indexed: 05/19/2024]
Abstract
BACKGROUND Traumatic brain injury (TBI) has become a major source of disability worldwide, increasing the interest in algorithms that use Artificial Intelligence (AI) to optimize the interpretation of imaging studies, prognosis estimation, and critical care issues. In this study we present a bibliometric analysis and Mini Review on the main uses that have been developed for TBI in AI. METHODS The results informing this review come from a Scopus database search as of April 15, 2023. The bibliometric analysis was carried out via the mapping bibliographic metrics method. Knowledge mapping was made in the VOSviewer software (V1.6.18), analyzing the "link strength" of networks based on co-occurrence of keywords, countries co-authorship and co-cited authors. In the mini-review section, we highlight the main findings and contributions of the studies. RESULTS A total of 495 scientific publications were identified from 2000 to 2023, with 9262 citations published since 2013. Among the 160 journals identified, The Journal of Neurotrauma, Frontiers in Neurology, and Plos One where those with the greatest number of publications. The most frequently co-occurring keywords were: "machine learning", "deep learning", "magnetic resonance imaging", and "intracranial pressure". The United States accounted for more collaborations than any other country, followed by United Kingdom and China. Four co-citation author clusters were found, and the top 20 papers were divided into reviews and original articles. CONCLUSION AI has become a relevant research field in TBI during the last 20 years, demonstrating great potential in imaging, but a more modest performance for prognostic estimation and neuromonitoring.

Non-Invasive Methods for Intracranial Pressure Monitoring in Traumatic Brain Injury Using Transcranial Doppler: A Scoping Review. J Neurotrauma 2024. [PMID: 37861291 DOI: 10.1089/neu.2023.0001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/21/2023] Open
Abstract
Intracranial pressure (ICP) monitoring is necessary for managing patients with traumatic brain injury (TBI). Although gold-standard methods include intraventricular or intraparenchymal transducers, these systems cannot be used in patients with coagulopathies or in those who are at high risk of catheter-related infections, nor can they be used in resource-constrained settings. Therefore, a non-invasive modality that is more widely available, cost effective, and safe would have tremendous impact. Among such non-invasive choices, transcranial Doppler (TCD) provides indirect ICP estimates through waveform analysis of cerebral hemodynamic changes. The objective of this scoping review is to describe the existing evidence for the use of TCD-derived methods in estimating ICP in adult TBI patients as compared with gold-standard invasive methods. This review was conducted in accordance with the Joanna Briggs Institute methodology for scoping reviews, with a main search of PubMed and Embase. The search was limited to studies conducted in adult TBI patients published in any language between 2012 and 2022. Twenty-two studies were included for analysis, with most being prospective studies conducted in high-income countries. TCD-derived non-invasive ICP (nICP) methods are either mathematical or non-mathematical, with the former having slightly better correlation with invasive methods, especially when using time-trending ICP dynamics over one-time estimated values. Nevertheless, mathematical methods are associated with greater cost and complexity in their application. Formula-based methods showed promise in excluding elevated ICP, exhibiting a high negative predictive value. Therefore, TCD-derived methods could be useful in assessing ICP changes instead of absolute ICP values for high-risk patients, especially in low-resource settings.

Abstract
OBJECTIVE This article aims to present a narrative review of current literature about the anatomical characteristics of the scalp as well as current practices in the management of surgical, traumatic and pressure injuries in the scalp, which are common in neurosurgery practice. METHOD We searched PubMed for publications and book chapters in English from 2011 to 2021. We also included commonly referenced papers that we considered relevant to the subject with publication before these dates. We used the search terms 'laceration,' and/or 'neurosurgery' and/or, 'pressure injury,' and/or 'craniotomy,' and/or 'surgical incision' in combination with 'scalp,' and/or 'wound care.' We also searched the reference lists of publications identified by the search strategy and selected those that we judged relevant. RESULTS We pre-selected 52 articles that covered various aspects of anatomy, pathophysiology, scalp wound management, or general wound care that we considered applied to the anatomical region of our interest. After abstract review, we selected 34 articles that met our search criteria and were included in our review. CONCLUSION There is limited evidence regarding classification and care of scalp wounds. As a result, many of the current practices for scalp wound management are based on evidence derived from studies involving different anatomical regions, not considering its particular anatomy, vasculature and microbiome. Further research is needed for more comprehensive and effective protocols for the management of scalp injuries. However, this present review proposes responses to the identified gaps concerning the management of scalp wounds.

Using Optic Nerve Sheath Diameter for Intracranial Pressure (ICP) Monitoring in Traumatic Brain Injury: A Scoping Review. Neurocrit Care 2023:10.1007/s12028-023-01884-1. [PMID: 38114797 DOI: 10.1007/s12028-023-01884-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 10/19/2023] [Indexed: 12/21/2023]
Abstract
INTRODUCTION Neuromonitoring represents a cornerstone in the comprehensive management of patients with traumatic brain injury (TBI), allowing for early detection of complications such as increased intracranial pressure (ICP) [1]. This has led to a search for noninvasive modalities that are reliable and deployable at bedside. Among these, ultrasonographic optic nerve sheath diameter (ONSD) measurement is a strong contender, estimating ICP by quantifying the distension of the optic nerve at higher ICP values. Thus, this scoping review seeks to describe the existing evidence for the use of ONSD in estimating ICP in adult TBI patients as compared to gold-standard invasive methods. MATERIALS AND METHODS This review was conducted in accordance with the Joanna Briggs Institute methodology for scoping reviews, with a main search of PubMed and EMBASE. The search was limited to studies of adult patients with TBI published in any language between 2012 and 2022. Sixteen studies were included for analysis, with all studies conducted in high-income countries. RESULTS All of the studies reviewed measured ONSD using the same probe frequency. In most studies, the marker position for ONSD measurement was initially 3 mm behind the globe, retina, or papilla. A few studies utilized additional parameters such as the ONSD/ETD (eyeball transverse diameter) ratio or ODE (optic disc elevation), which also exhibit high sensitivity and reliability. CONCLUSION Overall, ONSD exhibits great test accuracy and has a strong, almost linear correlation with invasive methods. Thus, ONSD should be considered one of the most effective noninvasive techniques for ICP estimation in TBI patients.

Abstract
OBJECTIVE To explore the available evidence on hyperosmolar therapies(HT) in mild and moderate traumatic brain injury(TBI) and to evaluate the effects on outcomes.A scoping review was conducted according to the Joanna Briggs Institute methodology. Inclusion criteria: (a)randomized controlled trials(RCTs), prospective and retrospective cohort studies and case-control studies; (b)all-ages mild and moderate TBIs; (c)HT administration; (d)functional outcomes recorded; (e)comparator group. RESULTS From 4424 records, only 3 respected the inclusion criteria. In a retrospective cohort study of adult moderate TBIs, the Glasgow Coma Scale(GCS) remained the same at 48 hours in those treated with hypertonic saline(HTS) while it worsened in the non-treated. A trend toward increased pulmonary infections and length of stay was found. In an RCT of adult severe and moderate TBIs, moderate TBIs treated with HTS showed a trend toward better secondary outcomes than standard care alone, with similar odds of adverse effects. An RCT enrolling children with mild TBI found a significant improvement in concussive pain immediately after HTS administration and after 2-3 days. No adverse events occurred. CONCLUSIONS A gap in the literature about HTs' role in mild and moderate TBI was found. Some benefits may exist with limited side effects and further studies are desirable.

Abstract
OBJECTIVE Expanded access to training opportunities is necessary to address 5 million essential neurosurgical cases not performed annually, nearly all in low- and middle-income countries. To target this critical neurosurgical workforce issue and advance positive collaborations, a summit (Global Neurosurgery 2019: A Practical Symposium) was designed to assemble stakeholders in global neurosurgical clinical education to discuss innovative platforms for clinical neurosurgery fellowships. METHODS The Global Neurosurgery Education Summit was held in November 2021, with 30 presentations from directors and trainees in existing global neurosurgical clinical fellowships. Presenters were selected based on chain referral sampling from suggestions made primarily from young neurosurgeons in low- and middle-income countries. Presentations focused on the perspectives of hosts, local champions, and trainees on clinical global neurosurgery fellowships and virtual learning resources. This conference sought to identify factors for success in overcoming barriers to improving access, equity, throughput, and quality of clinical global neurosurgery fellowships. A preconference survey was disseminated to attendees. RESULTS Presentations included in-country training courses, twinning programs, provision of surgical laboratories and resources, existing virtual educational resources, and virtual teaching technologies, with reference to their applicability to hybrid training fellowships. Virtual learning resources developed during the coronavirus disease 2019 pandemic and high-fidelity surgical simulators were presented, some for the first time to this audience. CONCLUSIONS The summit provided a forum for discussion of challenges and opportunities for developing a collaborative consortium capable of designing a pilot program for efficient, sustainable, accessible, and affordable clinical neurosurgery fellowship models for the future.

Abstract
Trauma registries play an important role in building capacity for trauma systems. Regularly, trauma registries exist in high-income countries (HICs) but not in low- and middle-income countries (LMICs). Neurotrauma includes common conditions, like traumatic brain injuries (TBIs) and spinal cord injuries. The development of organized neurotrauma care is crucial for improving the quality of care in less-resourced areas. The recent article published in International Journal of Health Policy and Management by Barthélemy et al entitled "Neurotrauma Surveillance in National Registries of Low- and Middle-Income Countries: A Scoping Review and Comparative Analysis of Data Dictionaries" adds an important body of literature to improve understanding of the importance of these types of efforts by promoting organized neurotrauma care systems in LMICs. Here, we provide a short commentary based on our experience with the Latin America and the Caribbean Neurotrauma Registry (LATINO-TBI) in the Latin America (LATAM) region.

Abstract
Background
Traumatic brain injury (TBI) has a disproportionately greater impact in low- and middle-income countries (LMICs). One strategy to reduce the burden of disease in LMICs is through the implementation of a trauma registry that standardizes the assessment of each patient's management of care.
Objective
This study aims to ascertain the interest of Latin America and the Caribbean (LAC) nations in establishing a shared neurotrauma registry in the regional block, based on an existing framework for collaboration.
Methods
A descriptive review was performed regarding the interests of LAC nations in implementing a shared neurotrauma registry in their region. We convened a meeting with seven Caribbean and five Latin American nations.
Results
One hundred percent (
n
= 12) of the LAC representatives including neurosurgeons, neurointensivists, ministers of health, and chief medical officers/emergency medical technicians (EMTs) agreed to adopt the registry for tracking the burden of TBI and associated pathologies within the region.
Conclusion
The implementation of a neurotrauma registry can benefit the region through a shared database to track disease, improve outcomes, build research, and ultimately influence policy.

Abstract
Spinal cord injury (SCI) is a disease that affects the normal function of the spinal cord. Road traffic accidents (RTAs) represent the main cause of SCI worldwide. SCI may generate physical disability and economic dependency, which is especially significant in low- and middle-income countries such as most of the Latin American countries. The main objective of this study was to present an epidemiological review of SCI secondary to RTAs. Stronger evidence on this condition in Latin America is important for future-specific data collection and prevention strategies. A literature review was carried out using specific search strategies in databases of indexed journals from the period 2000 to 2019. Data on SCI secondary to RTAs in the Latin American region were collected and analyzed. After initial screening and removal of duplicates, 16 articles met the inclusion criteria and were chosen for analysis. Data from 7 Latin American countries were retrievable. On average, RTAs were responsible for 40.81% of SCI. Data from different studies are heterogeneous. Car accidents and moto accidents were equally responsible for SCIs (50.61% vs. 49.06%). The thoracic segments were the most commonly affected (57.87%). Males in their 30s were the most affected category (76.6%). SCI due to RTAs may represent a severe but preventable condition that affects mostly men in their productive age, generating important social and economic issues. Data about this condition in Latin America are scarce, and could limit prevention and treatment strategies. Prospective data collection about this condition is recommended.

Exploring perspectives and adherence to guidelines for adult spinal trauma in low and middle-income healthcare economies: A survey on barriers and possible solutions (part I). BRAIN AND SPINE 2022; 2:100932.

Abstract
Most spinal trauma occurs in low- and middle-income countries (LMICs), but some elements may limit the application of current guidelines. In LMICs, a respectable proportion of physicians treating spinal trauma is not aware of any guidelines on this topic. Most physicians managing spinal trauma in LMICs believe that following the guidelines may positively affect patient outcomes. Most believed they have the capability to apply, the guidelines, but variation according to income and geographical region exists. The perceived limitations and their relevance to guideline adherence vary across different income and geographic areas worldwide. Resource-targeted guidelines for spinal trauma are considered a valuable option to overcome the limitations of real-life application of the current guidelines.

Abstract
BACKGROUND Traumatic brain injury (TBI) is going to be the third-leading cause of death worldwide, according to the WHO. Two European surveys suggested that adherence to brain trauma guidelines is poor. No study has compared compliance between low- (LMICs) and high-income (UHICs) countries. Hence, this study aimed to investigate differences in the management of severe TBI patients, comparing low- and high-income, and adherence to the BTF guidelines. METHODS A web-based survey was spread through the Global Neuro Foundation, different neurosurgical societies, and social media. RESULTS A total of 803 neurosurgeons participated: 70.4 from UHICs and 29.6% from LMICs. Hypertonic was administered as an early measure by the 73% and 65% of the responders in LMICs and UHICs, respectively (P=0.016). An invasive intracranial pressure monitoring was recommended by the 66% and 58% of the neurosurgeons in LMICs and UHICs, respectively (P<0.001). Antiseizure drugs (P<0.001) were given most frequently in LMICs as, against recommendations, steroids (87% vs. 61% and 86% vs. 81%, respectively). In the LMICs both the evacuation of the contusion and decompressive craniectomy were performed earlier than in UHICs (30% vs. 17% with P<0.001 and 44% vs. 28% with P=0.006, respectively). In the LMICs, the head CT control was performed mostly between 12 and 24 hours from the first imaging (38% vs. 23%, P<0.001). CONCLUSIONS The current Guidelines on TBI do not always fit to both the resources and circumstances in different countries. Future research and clinical practice guidelines should reflect the greater relevance of TBI in low resource settings.

Abstract
BACKGROUND Globally, 69 million people suffer from traumatic brain injury (TBI) each year and TBI is the most common cause of subarachnoid hemorrhage (SAH). Traumatic SAH (TSAH) has been described as an adverse prognostic factor leading to progressive neurological deterioration and an increase in morbidity and mortality, but there are a limited number of studies which evaluate recent trends in the diagnostic and management of SAH in the context of trauma. OBJECTIVE The objective of this scoping review was to understand the extent and type of evidence in relation to the diagnostic criteria and management of TSAH. METHODS This scoping review will be conducted in accordance with the Joanna Briggs Institute methodology for scoping reviews. A 3-step search strategy (an initial limited search in PubMed and Scopus databases; a main search of EMBASE, Web of Science, EBSCO, MEDLINE; and manual searches of reference lists of included articles) will be utilized. The search will be limited to studies with human participants and published in English, Spanish, and French between 2005 and 2020. This review will consider studies of adolescent and adult patients with SAH secondary to trauma. Study selection will be performed by 2 authors (DG and LF) in a 2-phase process; if any disagreement arises, a third author (AR) will be consulted. Data to be extracted from each study will include population, intervention, comparator and outcome measures, and a summary of findings. Citation screening, full-text review, risk of bias assessment, and extraction of study characteristics and outcomes will be carried out using a web-based software platform that streamlines the production of scoping reviews. RESULTS Ethics approval is not required for this systematic review, as there will be no patient involvement. The search for this systematic review commenced in December 2020, and we expect to publish the findings in early 2021. The plan for dissemination is to publish review findings in a peer-reviewed journal and present findings at conferences that engage the most pertinent stakeholders. CONCLUSIONS This scoping review will serve as an initial step in providing more evidence for health care professionals, economists, and policymakers so that they might devote more resources toward this significant problem affecting both health and economic outcomes worldwide.

Abstract
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.

Abstract
BACKGROUND The Brain Trauma Foundation (BTF) published evidence-based guidelines with a detailed approach to the management of intracranial hypertension (ICH) in traumatic brain injury (TBI) patients. However, management with cerebrospinal fluid (CSF) drainage in TBI patients remains a controversial topic and is a recent addition to the 4th Edition of the BTF guidelines. External lumbar drainage (ELD) has been proposed for the management of patients with refractory ICH despite aggressive measures. ELD has been described in the literature with possible benefits in outcomes; still, many questions remain unanswered. METHODS A systematic search on MEDLINE was conducted for articles that studied lumbar CSF drainage in adult TBI patients with ICH. RESULTS Eleven studies met the inclusion criteria, which included 5 prospective and 6 retrospective studies. Several studies showed that CSF drainage via lumbar drain resulted in significant reduction of ICP compared to before ELD placement and had a low complication rate. However, the data reporting mortality and functional outcomes are varied across studies. CONCLUSION The literature suggests that ELD may play a role in the management of refractory ICH in TBI patients when first and second-tier measures fail and may be a safe, effective, and minimally invasive method to significantly lower ICP. Additional research and standardized treatment protocols are necessary.

OBJECTIVE Traumatic brain injuries (TBIs) are a significant disease burden worldwide. It is imperative to improve neurosurgeons' training during and after their medical residency with appropriate neurotrauma competencies. Unfortunately, the development of these competencies during neurosurgeons' careers and in daily practice is very heterogeneous. This article aimed to describe the development and evaluation of a competency-based international course curriculum designed to address a broad spectrum of needs for taking care of patients with neurotrauma with basic and advanced interventions in different scenarios around the world. METHODS A committee of 5 academic neurosurgeons was involved in the task of building this course curriculum. The process started with the identification of the problems to be addressed and the subsequent performance needed. After this, competencies were defined. In the final phase, educational activities were designed to achieve the intended learning outcomes. In the end, the entire process resulted in competency and outcomes-based education strategy, including a definition of all learning activities and learning outcomes (curriculum), that can be integrated with a faculty development process, including training. Further development was completed by 4 additional academic neurosurgeons supported by a curriculum developer specialist and a project manager. After the development of the course curriculum, template programs were developed with core and optional content defined for implementation and evaluation. RESULTS The content of the course curriculum is divided into essentials and advanced concepts and interventions in neurotrauma care. A mixed sample of 1583 neurosurgeons and neurosurgery residents attending 36 continuing medical education activities in 30 different cities around the world evaluated the course. The average satisfaction was 97%. The average usefulness score was 4.2, according to the Likert scale. CONCLUSIONS An international competency-based course curriculum is an option for creating a well-accepted neurotrauma educational process designed to address a broad spectrum of needs that a neurotrauma practitioner faces during the basic and advanced care of patients in different regions of the world. This process may also be applied to other areas of the neurosurgical knowledge spectrum. Moreover, this process allows worldwide standardization of knowledge requirements and competencies, such that training may be better benchmarked between countries regardless of their income level.

Harnessing inter-disciplinary collaboration to improve emergency care in low- and middle-income countries (LMICs): results of research prioritisation setting exercise. BMC Emerg Med 2020; 20:68. [PMID: 32867675 PMCID: PMC7457362 DOI: 10.1186/s12873-020-00362-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 08/19/2020] [Indexed: 01/16/2023] Open
Abstract
BACKGROUND More than half of deaths in low- and middle-income countries (LMICs) result from conditions that could be treated with emergency care - an integral component of universal health coverage (UHC) - through timely access to lifesaving interventions. METHODS The World Health Organization (WHO) aims to extend UHC to a further 1 billion people by 2023, yet evidence supporting improved emergency care coverage is lacking. In this article, we explore four phases of a research prioritisation setting (RPS) exercise conducted by researchers and stakeholders from South Africa, Egypt, Nepal, Jamaica, Tanzania, Trinidad and Tobago, Tunisia, Colombia, Ethiopia, Iran, Jordan, Malaysia, South Korea and Phillipines, USA and UK as a key step in gathering evidence required by policy makers and practitioners for the strengthening of emergency care systems in limited-resource settings. RESULTS The RPS proposed seven priority research questions addressing: identification of context-relevant emergency care indicators, barriers to effective emergency care; accuracy and impact of triage tools; potential quality improvement via registries; characteristics of people seeking emergency care; best practices for staff training and retention; and cost effectiveness of critical care - all within LMICs. CONCLUSIONS Convened by WHO and facilitated by the University of Sheffield, the Global Emergency Care Research Network project (GEM-CARN) brought together a coalition of 16 countries to identify research priorities for strengthening emergency care in LMICs. Our article further assesses the quality of the RPS exercise and reviews the current evidence supporting the identified priorities.

Abstract
Objective
Traumatic brain injuries (TBIs) are devastating injuries and represent a major cause of morbidity and mortality worldwide. Traffic accidents are one of the main causes, especially in low- and middle-income countries. The epidemiology of TBI due to road traffic in Latin America is not clearly documented.
Methods
A narrative review was conducted using PubMed, SCOPUS, and Google Scholar, looking for TBI studies in Latin America published between 2000 and 2018. Seventeen studies were found that met the inclusion and exclusion criteria.
Results
It was found that TBI due to road traffic accidents (RTAs) is more frequent in males between the ages of 15 and 35 years, and patients in motor vehicles accounted for most cases, followed by pedestrians, motorcyclists, and cyclists.
Conclusion
Road traffic accidents is a common cause of TBI in Latin America. More studies and registries are needed to properly document the epidemiological profiles of TBI related to RTAs.

The Role of Decompressive Craniectomy in the Context of Severe Traumatic Brain Injury: Summary of Results and Analysis of the Confidence Level of Conclusions From Systematic Reviews and Meta-Analyses. Front Neurol 2019; 10:1063. [PMID: 31649610 PMCID: PMC6795698 DOI: 10.3389/fneur.2019.01063] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Accepted: 09/20/2019] [Indexed: 12/26/2022] Open
Abstract
Introduction: Traumatic brain injury (TBI) is a global epidemic. The incidence of TBI in low and middle-income countries (LMICs) is three times greater than in high-income countries (HICs). Decompressive craniectomy (DC) is a surgical procedure to reduce intracranial pressure (ICP) and prevent secondary injury. Multiple comparative studies, and several randomized controlled trials (RCTs) have been conducted to investigate the influence of DC for patients with severe TBI on outcomes such as mortality, ICP, neurological outcomes, and intensive care unit (ICU) and hospital length of stay. The results of these studies are inconsistent. Systematic reviews and meta-analyses have been conducted in an effort to aggregate the data from the individual studies, and perhaps derive reliable conclusions. The purpose of this project was to conduct a review of the reviews about the effectiveness of DC to improve outcomes. Methods: We conducted a systematic search of the literature to identify reviews and meta-analyses that met our pre-determined criteria. We used the AMSTAR 2 instrument to assess the quality of each of the included reviews, and determine the level of confidence. Results: Of 973 citations from the original search, five publications were included in our review. Four of them included meta-analyses. For mortality, three reviews found a positive effect of DC compared to medical management and two found no significant difference between groups. The four reviews that measured neurological outcome found no benefit of DC. The two reviews that assessed ICP both found DC to be beneficial in reducing ICP. DC demonstrated a significant reduction in ICU length of stay in the one study that measured it, and a significant reduction in hospital length of stay in the two studies that measured it. According to the AMSTAR 2 criteria, the five reviews ranged in levels of confidence from low to critically low. Conclusion: Systematic reviews and meta-analyses are important approaches for aggregating information from multiple studies. Clinicians rely of these methods for concise interpretation of scientific literature. Standards for quality of systematic reviews and meta-analyses have been established to support the quality of the reviews being produced. In the case of DC, more attention must be paid to quality standards, in the generation of both individual studies and reviews.

Abstract
Decompressive craniectomy (DC) is a neurosurgical procedure useful to prevent and manage the impact of high intracranial pressure (ICP) that leads to brain herniation and brain's tissue ischemia. In well-resourced environment this procedure has been proposed as a last tier therapy when ICP is not controlled by medical therapies in the management of different neurosurgical emergencies like traumatic brain injury (TBI), stroke, infectious diseases, hydrocephalus, tumors, etc. The purpose of this narrative review is to discuss the role of DC in areas of low neurosurgical and neurocritical care resources. We performed a literature review with a specific search strategy in web repositories and some local and regional journals from Low and Middle-Income Countries (LMICs). The most common publications include case reports, case series and observational studies describing the benefits of the procedure on different pathologies but with several types of biases due to the absence of robust studies or clinical registries analysis in these kinds of environments.

Abstract
Traumatic brain injury according to the World Health Organization estimates that by 2020 will be the third leading cause of morbidity and mortality worldwide. Intracranial hypertension refractory to medical management is the cause of increased mortality in neurotrauma. There are various measures to control intracranial hypertension, including surgical. Decompressive craniectomy has been routinely used to treat intracranial hypertension secondary to cerebral infarction, subarachnoid hemorrhage, intracerebral hemorrhage and trauma. We review the literature to describe the mechanisms, types and indications for this procedure.

Abstract
OBJECTIVETraumatic brain injury (TBI)-the "silent epidemic"-contributes to worldwide death and disability more than any other traumatic insult. Yet, TBI incidence and distribution across regions and socioeconomic divides remain unknown. In an effort to promote advocacy, understanding, and targeted intervention, the authors sought to quantify the case burden of TBI across World Health Organization (WHO) regions and World Bank (WB) income groups.METHODSOpen-source epidemiological data on road traffic injuries (RTIs) were used to model the incidence of TBI using literature-derived ratios. First, a systematic review on the proportion of RTIs resulting in TBI was conducted, and a meta-analysis of study-derived proportions was performed. Next, a separate systematic review identified primary source studies describing mechanisms of injury contributing to TBI, and an additional meta-analysis yielded a proportion of TBI that is secondary to the mechanism of RTI. Then, the incidence of RTI as published by the Global Burden of Disease Study 2015 was applied to these two ratios to generate the incidence and estimated case volume of TBI for each WHO region and WB income group.RESULTSRelevant articles and registries were identified via systematic review; study quality was higher in the high-income countries (HICs) than in the low- and middle-income countries (LMICs). Sixty-nine million (95% CI 64-74 million) individuals worldwide are estimated to sustain a TBI each year. The proportion of TBIs resulting from road traffic collisions was greatest in Africa and Southeast Asia (both 56%) and lowest in North America (25%). The incidence of RTI was similar in Southeast Asia (1.5% of the population per year) and Europe (1.2%). The overall incidence of TBI per 100,000 people was greatest in North America (1299 cases, 95% CI 650-1947) and Europe (1012 cases, 95% CI 911-1113) and least in Africa (801 cases, 95% CI 732-871) and the Eastern Mediterranean (897 cases, 95% CI 771-1023). The LMICs experience nearly 3 times more cases of TBI proportionally than HICs.CONCLUSIONSSixty-nine million (95% CI 64-74 million) individuals are estimated to suffer TBI from all causes each year, with the Southeast Asian and Western Pacific regions experiencing the greatest overall burden of disease. Head injury following road traffic collision is more common in LMICs, and the proportion of TBIs secondary to road traffic collision is likewise greatest in these countries. Meanwhile, the estimated incidence of TBI is highest in regions with higher-quality data, specifically in North America and Europe.

Abstract
BACKGROUND Trauma contributes more than ten percent of the global burden of disease. Initial assessment and resuscitation of trauma patients often requires rapid diagnosis and management of multiple concurrent complex conditions, and errors are common. We investigated whether implementing a trauma care checklist would improve care for injured patients in low-, middle-, and high-income countries. METHODS From 2010 to 2012, the impact of the World Health Organization (WHO) Trauma Care Checklist program was assessed in 11 hospitals using a stepped wedge pre- and post-intervention comparison with randomly assigned intervention start dates. Study sites represented nine countries with diverse economic and geographic contexts. Primary end points were adherence to process of care measures; secondary data on morbidity and mortality were also collected. Multilevel logistic regression models examined differences in measures pre- versus post-intervention, accounting for patient age, gender, injury severity, and center-specific variability. RESULTS Data were collected on 1641 patients before and 1781 after program implementation. Patient age (mean 34 ± 18 vs. 34 ± 18), sex (21 vs. 22 % female), and the proportion of patients with injury severity scores (ISS) ≥ 25 (10 vs. 10 %) were similar before and after checklist implementation (p > 0.05). Improvement was found for 18 of 19 process measures, including greater odds of having abdominal examination (OR 3.26), chest auscultation (OR 2.68), and distal pulse examination (OR 2.33) (all p < 0.05). These changes were robust to several sensitivity analyses. CONCLUSIONS Implementation of the WHO Trauma Care Checklist was associated with substantial improvements in patient care process measures among a cohort of patients in diverse settings.

Abstract
INTRODUCTION Trauma quality improvement (QI) programs have been shown to improve outcomes and decrease cost. These are high priorities in low- and middle-income countries (LMICs), where 2,000,000 deaths due to survivable injuries occur each year. We sought to define areas for improvement in trauma QI programs in four LMICs. METHODS We conducted a survey among trauma care providers in four Andean middle-income countries: Bolivia, Colombia, Ecuador, and Peru. RESULTS 336 physicians, medical students, nurses, administrators and paramedical professionals responded to the cross-sectional survey with a response rate greater than 90% in all included countries except Bolivia, where the response rate was 14%. Eighty-seven percent of respondents reported morbidity and mortality (M&M) conferences occur at their hospital. Conferences were often reported as infrequent - 45% occurred less than every three months and poorly attended - 63% had five or fewer staff physicians present. Only 23% of conferences had standardized selection criteria, most lacked documentation - notes were taken at only 35% of conferences. Importantly, only 13% of participants indicated that discussions were routinely followed-up with any sort of corrective action. Multivariable analysis revealed the presence of standardized case selection criteria (OR 3.48, 95% CI 1.16-10.46), written documentation of the M&M conferences (OR 5.73, 95% CI 1.73-19.06), and a clear plan for follow-up (OR 4.80, 95% CI 1.59-14.50) to be associated with effective M&M conferences. Twenty-two percent of respondents worked at hospitals with a trauma registry. Fifty-two percent worked at institutions where autopsies were conducted, but only 32% of those reported the autopsy results to ever be used to improve hospital practice. CONCLUSIONS M&M conferences are frequently practiced in the Andean region of Latin America but often lack methodologic rigor and thus effectiveness. Next steps in the maturation of QI programs include optimizing use of data from autopsies and registries, and systematic follow-up of M&M conferences with corrective action to ensure that these activities result in appreciable changes in clinical care.

Abstract
Abstract
The dural venous sinus thrombosis is a benign disease, representing about 1% of cerebral vascular events. In some cases the development of the disease increased intracranial pressure or symptomatic epilepsy. The development towards a dural venous sinus thrombosis is rare, but is a condition to be considered before the development of ischemic vascular events and a history of recent head trauma. Intracranial hematomas or skull fractures can lead to the establishment of obstructive pathology of the dural venous sinuses. The knowledge of this entity is necessary for the critical care staff and neurosurgery staff.

Abstract
Balint’s syndrome is a rare neurological disorder associated with bilateral parieto-occipital damage which was described by Rezsö Bálint in 1909.The syndrome is manifested clinically by the presence of a hemispatial negligence. The lesion is usually inside parietooccipital region bilaterally in most cases but may also be compromised angular convolutions, the dorsolateral area of the occipital lobe as the superior parietal lobule. We herein report a 61-year-old man with traumatic brain injury who was diagnosed to have right parieto-occipital contusion in radiologic evaluation. Physical examination was consistent with Balint's syndrome. The patient was followed for 12 months post-injury and received 4-months of outpatient rehabilitation. Patient showed improvement of Balint’s syndrome 8 months after the starts of symptoms.

Abstract
Objective The Pan-American Trauma Society (PTS) developed a Trauma and Emergency Ultrasound Course (USET) in response to the requirement for trauma ultrasound training for low-and middle-income countries. The objective of this study was to evaluate the efficiency of this course. Method Pre- and post-course tests were used. And interval estimation of proportions was calculated at 95% CI. Theoretical and practical pre- and post-course knowledge were assessed with the Wilcoxon Signed Rank test at 0.05 level of statistical significance. Result Between 2005 and 2007, 114 students, including general surgeons, emergency medicine physicians, anesthesiologists, critical care physicians, and residents of these specialties, were trained in seven countries (Uruguay, Peru, Mexico, Venezuela, Aruba, Colombia, and Ecuador). The difference on complete knowledge ranked scores before and after the course was statistically significant (p<0.001). After the course, almost all participants (97.4%) demonstrated complete knowledge in final evaluation. Conclusion The USET course is an effective approach for trauma ultrasound training. Specific training programs for trauma care providers that work in low-and middle-income countries are necessary and could be performed with low cost training programs.

Abstract
INTRODUCTION Severe traumatic brain injury (sTBI) is a disease that generates significant mortality and disability in Latin America, and specifically in Colombia. The purpose of this study was to evaluate the 12-month clinical outcome in patients with sTBI managed with an early cranial decompression (ECD) as the main procedure for damage control (DC) therapy, performed in a University Hospital in Colombia over a 4-year period. MATERIALS AND METHODS A database of 106 patients who received the ECD procedure, and were managed according to the strategy for DC in neurotrauma, was analyzed. Variables were evaluated, and the patient outcome was determined according to the Glasgow Outcome Score (GOS) at 12 months postinjury. This was used to generate a dichotomous variable with "favorable" (GOS of 4 or 5) or "unfavorable" (GOS of 1-3) outcomes; analysis of variance was performed with the Chi-square, Wilcoxon-Mann-Whitney and Fisher tests. RESULTS An overall survival rate of 74.6% was observed for the procedure, At 12 months postsurgery, a favorable clinical outcome (GOS 4-5) was found in 70 patients (66.1%), Unfavorable outcomes in patients were associated with the following factors: Closed trauma, an Injury Severity Score >16, obliterated basal cisterns, subdural hematoma as the main injury seen on the admission computed tomography, and nonreactive pupils observed in the emergency department. CONCLUSION Twelve months outcome of patients with sTBI managed with ECD in a neuromonitoring limited resource University Hospital in Colombia shows an important survival rate with favorable clinical outcome measure with GOS.

Abstract
Penetrating orbital-cranial injuries (POCIs) are difficult cases especially in hospitals in low-middle-income countries (LMIC) where resources are limited. We present a case series of POCI managed in a university hospital in such scenario. A retrospective case series was conducted including patients with POCI in 2011. Mechanism of injury, Glasgow Coma Scale score, imaging, medical and surgical management, complications, and Glasgow Outcome Scale (GOS) score were analyzed. A total of 30 patients with penetrating orbital injuries were admitted from March 2011 to December 2011. Of this group, only four patients were diagnosed with cranial penetration. Computed tomography (CT) angiography revealed orbital fractures and injury to frontal, temporal, or occipital lobes. Urgent craniotomy with isolation of ipsilateral carotid artery was performed. GOS score at discharge was 5 in three patients and 4 in one patient. POCIs are not uncommon in hospitals of LMIC. In such scenarios, a standard approach with CT angiography and early neurosurgical intervention results in good outcome.

Abstract
OBJECTIVE To determine the effects of glycemic level on outcome patients with traumatic brain injury. METHODS From September 2010 to December 2012, all medical records of adult patients with TBI admitted to the Emergency Room of Laura Daniela Clinic in Valledupar City, Colombia, South America were enrolled. Both genders between 18 and 85 years who referred during the first 48 hours after trauma, and their glucose level was determined in the first 24 hours of admission were included. Adults older than 85 years, with absence of Glasgow Coma Scale (GCS) score and a brain Computerized Tomography (CT) scans were excluded. The cut-off value was considered 200 mg/dL to define hyperglycemia. Final GCS, hospital admission duration and complications were compared between normoglycemic and hyperglycemic patients. RESULTS Totally 217 patients were identified with TBI. Considering exclusion criteria, 89 patients remained for analysis. The mean age was 43.0±19.6 years, the mean time of remission was 5.9±9.4 hours, the mean GCS on admission was 10.5±3.6 and the mean blood glucose level in the first 24 hours was 138.1±59.4 mg/dL. Hyperglycemia was present in 13.5% of patients. The most common lesions presented by patients with TBI were fractures (22.5%), hematoma (18.3%), cerebral edema (18.3%) and cerebral contusion (16.2%). Most of patients without a high glucose level at admission were managed only medically, whereas surgical treatment was more frequent in patients with hyperglycemia (p=0.042). Hyperglycemia was associated with higher complication (p=0.019) and mortality rate (p=0.039). GCS was negatively associated with on admission glucose level (r=0.11; p=0.46). CONCLUSION Hyperglycemia in the first 24-hours of TBI is associated with higher rate of surgical intervention, higher complication and mortality rates. So hyperglycemia handling is critical to the outcome of patients with traumatic brain injury.

Traumatic brain injury is a public health problem and leading cause of death. In the context of a severe head injury, monitoring strategies give us the option to analyze the posterior intracranial alterations to the primary lesion. Neuromonitoring allows us to identify the deterioration of neurological function and the presence of secondary brain injury that may benefit from a therapeutic intervention letting us know pathophysiological changes that occur in a patient with brain injury. Understanding the physiological data allow to individualize therapies and interpret variables that ultimately help us choice a better treatment.

The effect of admission spontaneous hypothermia on patients with severe traumatic brain injury. Injury 2013; 44:1219-25. [PMID: 23273319 PMCID: PMC3644529 DOI: 10.1016/j.injury.2012.11.026] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2012] [Revised: 11/09/2012] [Accepted: 11/25/2012] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Recent information has emerged regarding the harmful effects of spontaneous hypothermia at time of admission in trauma patients. However the volume of evidence regarding the role of spontaneous hypothermia in TBI patients is inadequate. METHODS We performed secondary data analysis of 10 years of the Pennsylvania trauma outcome study (PTOS) database. Unadjusted comparisons of the association of admission spontaneous hypothermia with mortality were performed. In addition, full assessment of the association of hypothermia with mortality was conducted using multivariable logistic regressions reporting the odds ratios (OR) with the 95% confidence intervals (CI) and P-values. RESULTS There were 11,033 patients identified from the PTOS with severe TBI. There were 4839 deaths (43.9%). The proportion of deaths in hypothermic patients was higher than the proportion of deaths in normothermic patients (53.9% vs. 37.4% respectively; P value<0.001). In a multivariable logistic regression model adjusted for demographics, injury characteristics, and information at admission to the trauma centre, the odds of death among patients with hypothermia were 1.70 times the odds of death among patients with normothermia (OR 1.70, 95% CI 1.50-1.93), indicating that the probability of death was significantly higher when patients arrived hypothermic at the trauma centre. CONCLUSION The presence of spontaneous hypothermia at hospital admission is associated with a significant increase in the risk of mortality in patients with severe TBI. The benefit of maintaining normothermia in severe TBI patients, the impact of prolonged re-warming in patients with established hypothermia and the introduction of prophylactic measures to complications of hypothermia are key points that require further investigation.

Abstract
OBJECTIVE : To determine trends for in-hospital survival and functional outcomes at acute care hospital discharge for patients with severe adult traumatic brain injury (SATBI) in Pennsylvania, during 1998 to 2007. METHODS : Secondary analysis of the Pennsylvania trauma outcome study database. MAIN OUTCOME MEASURES : Survival and functional status scores of 5 domains (feeding, locomotion, expression, transfer mobility, and social interaction) fitted into logistic regression models adjusted for age, sex, race, comorbidities, injury mechanism, extracranial injuries, severity scores, hospital stay, trauma center, and hospital level. Sensitivity analyses for functional outcomes were performed. RESULTS : There were 26 234 SATBI patients. Annual numbers of SATBI increased from 1757 to 3808 during 1998 to 2007. Falls accounted for 47.7% of all SATBI. Survival increased significantly from 72.5% to 82.7% (odds ratio [OR] = 1.10, 95% CI: 1.08-1.11, P < .001). In sensitivity analyses, trends of complete independence in functional outcomes increased significantly for expression (OR = 1.01, 95% CI: 1.00-1.02, P = .011) and social interaction (OR = 1.01, 95% CI: 1.00-1.03, P = .002). There were no significant variations over time for feeding, locomotion, and transfer mobility. CONCLUSIONS : Trends for SATBI served by Pennsylvania's established trauma system showed increases in rates but substantial reductions in mortality and significant improvements in functional outcomes at discharge for expression and social interaction.

Abstract
INTRODUCTION In response to a requirement for advanced trauma care nurses to provide combat tactical medical support, the antinarcotics arm of the Colombian National Police (CNP) requested the Colombian National Prehospital Care Association to develop a Combat Tactical Medicine Course (MEDTAC course). OBJECTIVE To evaluate the effectiveness of this course in imparting knowledge and skills to the students. METHODS We trained 374 combat nurses using the novel MEDTAC course. We evaluated students using pre- and postcourse performance with a 45-question examination. Field simulations and live tissue exercises were evaluated by instructors using a Likert scale with possible choices of 1 to 4. Interval estimation of proportions was calculated with a 95% confidence interval (95% CI). Differences in didactic test scores were assessed using a t-test at 0.05 level of statistical significance. RESULTS Between March 2006 and July 2007, 374 combat nursing students of the CNP were trained. The difference between examination scores before and after the didactic part of the course was statistically significant (p < 0.01). After the practical session of the course, all participants (100%) demonstrated competency on final evaluation. CONCLUSIONS The MEDTAC course is an effective option improving the knowledge and skills of combat nurses serving in the CNP. MEDTAC represents a customized approach for military trauma care training in Colombia. This course is an example of specialized training available for groups that operate in austere environments with limited resources.
