Priestley DR, Staph J, Koneru SD, Rajtmajer SM, Cwiek A, Vervoordt S, Hillary FG. Establishing ground truth in the traumatic brain injury literature: if replication is the answer, then what are the questions? Brain Commun 2022; 5:fcac322. [PMID: 36601624 PMCID: PMC9806718 DOI: 10.1093/braincomms/fcac322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 09/09/2022] [Accepted: 12/06/2022] [Indexed: 12/13/2022] Open
Abstract
The replication crisis poses important challenges to modern science. Central to this challenge is re-establishing ground truths or the most fundamental theories that serve as the bedrock to a scientific community. However, the goal to identify hypotheses with the greatest support is non-trivial given the unprecedented rate of scientific publishing. In this era of high-volume science, the goal of this study is to sample from one research community within clinical neuroscience (traumatic brain injury) and track major trends that have shaped this literature over the past 50 years. To do so, we first conduct a decade-wise (1980-2019) network analysis to examine the scientific communities that shape this literature. To establish the robustness of our findings, we utilized searches from separate search engines (Web of Science; Semantic Scholar). As a second goal, we sought to determine the most highly cited hypotheses influencing the literature in each decade. In a third goal, we then searched for any papers referring to 'replication' or efforts to reproduce findings within our >50 000 paper dataset. From this search, 550 papers were analysed to determine the frequency and nature of formal replication studies over time. Finally, to maximize transparency, we provide a detailed procedure for the creation and analysis of our dataset, including a discussion of each of our major decision points, to facilitate similar efforts in other areas of neuroscience. We found that the unparalleled rate of scientific publishing within the brain injury literature combined with the scarcity of clear hypotheses in individual publications is a challenge to both evaluating accepted findings and determining paths forward to accelerate science. Additionally, while the conversation about reproducibility has increased over the past decade, the rate of published replication studies continues to be a negligible proportion of the research. Meta-science and computational methods offer the critical opportunity to assess the state of the science and illuminate pathways forward, but ultimately there is structural change needed in the brain injury literature and perhaps others.

Baiden F, Anto-Ocrah M, Adjei G, Gyaase S, Abebrese J, Punguyire D, Owusu-Agyei S, Moresky RT. Head Injury Prevalence in a Population of Injured Patients Seeking Care in Ghana, West Africa. Front Neurol 2022; 13:917294. [PMID: 35812104 PMCID: PMC9266767 DOI: 10.3389/fneur.2022.917294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 05/20/2022] [Indexed: 11/18/2022] Open
Abstract
Background/Significance: Much of the literature on head injury (HI) prevalence comes from high-income countries (HICs), despite the disproportionate burden of injuries in low to middle-income countries (LMICs). This study evaluated the HI prevalence in the Kintampo Injury Registry, a collaborative effort between Kintampo Health Research Centre (KHRC) in Ghana and the sidHARTe Program at Columbia University Mailman School of Public Health. In our first aim, we characterize the HI prevalence in the registry. In aim 2, we examine if there are any sex (male/female) differences in head injury outcomes in these populations for points of potential intervention. Methods Secondary analysis of data from the Kintampo Injury Registry which had 7,148 registered patients collected during January 2013 to January 2015. The definition of a case was adopted to ensure consistency with the International Statistical Classification of Diseases and Related Health Problems, revision 10 (ICD-10). A 3-page questionnaire was used to collect data from injured patients to include in the registry. The questions were designed to be consistent with the World Health Organization (WHO) guidelines on injury surveillance and were adapted from the questionnaire used in a pilot, multi-country injury study undertaken in other parts of Africa. The questionnaire collected information on the anatomic site of injury (e.g., head), mechanism of injury (e.g., road traffic injuries, interpersonal injuries (including domestic violence), falls, drowning, etc.), severity and circumstances of the injury, as well as precipitating factors, such as alcohol and drug use. The questionnaire consisted mainly of close-ended questions and was designed for efficient data entry. For the secondary data analyses for this manuscript, we only included those with “1st visit following injury” and excluded all transfers and follow-up visits (n = 834). We then dichotomized the remaining 6,314 patients to head injured and non-head injured patients based on responses to the variable “Nature of injury =Head Injury”. We used chi-square and Fisher's exact tests with p < 0.05 as cut-off for statistical significance. Logistic regression estimates were used for effect estimates. Results Of the 6,314 patients, there were 208 (3.3%) head-injured patients and 6,106 (96.7%) patients without head injury. Head-injured patients tended to be older (Mean age: 28.9 +/-13.7; vs. 26.1 +/- 15.8; p = 0.004). Seven in 10 head injured patients sustained their injuries via transport/road traffic accidents, and head-injured patients had 13 times the odds of mortality compared with those without head injuries (OR: 13.3; 95% CI: 8.05, 22.0; p < 0.0001) even though over half of them had mild or moderate injury severity scores (p < 0.001). Evaluation of sex differences amongst the head-injured showed that in age-adjusted logistic regression models, males had 1.4 times greater odds of being head injured (OR: 1.4; 95% CI: 1.04, 2.00; p = 0.03) and over twice the risk of mortality (OR: 2.7; 95% CI: 0.74, 10.00; p = 0.13) compared to females. Conclusion In these analyses, HI was associated with a higher risk of mortality, particularly amongst injured males; most of whom were injured in transport/road-traffic-related accidents. This study provides an impetus for shaping policy around head injury prevention in LMICs like Ghana.

Abstract
Objective Citation analyses identify the most-cited publications in a given field, which aids in understanding areas of the literature that are well-developed and those where additional research is required. Our objective was to perform a citation analysis in concussion to understand the state of the science from a bibliometric perspective. Design We performed a keyword search for articles related to concussion in Harzing's Publish or Perish, which scrapes Google Scholar for citation metrics. This approach was used to identify the 50 articles with the most lifetime citations as well as the 50 articles with the highest citation rate. Main outcome measures Citations and citation rates. Results Per our citation analysis, we found that concussion guidelines are among the most cited publications (comprising ≥20% of each citation cohort), yet there is a dearth of widely cited clinical trials to inform them; only one randomized trial (studying the effects of rest following concussion) was included in our citation analysis. The majority of study designs (≥40% of each citation cohort) were cross-sectional. Concussion recovery and secondary complications of concussion were common study topics, with ≥20% of publications in each citation cohort focused on these issues. The publications included in our analysis were authored by 596 authors from only 12 countries, suggesting a lack of global representation in concussion research. Conclusions Existing reviews and consensus statements have called for additional, high-quality research in concussion; our citation analysis quantifies this need. Further, although concussion is a global problem with its incidence and burden increasing in the developing world, our citation analysis demonstrates that the most-cited and discussed articles in concussion are published by authors from only 12 countries. Going forward, to address the global problem that is concussion, a more global research perspective is called for.

Abstract
INTRODUCTION Traumatic brain injuries (TBIs) are 1 of the most common reasons for young adult death and disability. This study sought to provide novel data for TBIs in Southern Punjab, as well as to identify any areas of service improvement to reduce the acute and long-term burden of this condition. METHODS A survey in English was created, which was then circulated to members of the emergency and neurosurgical department for a 3-wk period. RESULTS A total of 450 patients (379 male [84.2%] and 71 female [15.2%]) were included as TBI admissions or attendances with a mean age of 28.9 y. Of the total, 420 people (93.2%) had experienced a TBI following a road traffic incident (RTI), with 78.7% (n = 354) of TBIs involving motorbike users who were not wearing helmets. A total of 226 (50.1%) patients arrived by car to the hospital, and 201 (44.7%) arrived by means of provincial government-funded emergency ambulance services. CONCLUSIONS TBIs in Southern Punjab mostly affect younger males involved in RTIs while riding motorbikes. Recommendations to reduce the acute and long-term burden of TBIs in this region include formal training of all hospital and prehospital staff in the management of acute trauma cases according to international guidelines and operating provincial government emergency ambulance services in a wider geographic area.

Abstract
OBJECTIVE To determine minimally clinically important differences (MCIDs) for Disability Rating Scale (DRS), Fugl-Meyer Upper Extremity Subscale (FM-UE), Fugl-Meyer Lower Extremity Subscale (FM-LE), and Fugl-Meyer Motor Scale (FMMS) in patients with chronic motor deficits secondary to traumatic brain injury (TBI). METHODS Retrospective analysis from the 1-year, double-blind, randomized, surgical sham-controlled, Phase 2 STEMTRA trial (NCT02416492), in which patients with chronic motor deficits secondary to TBI (N = 61) underwent intracerebral stereotactic implantation of modified bone marrow-derived mesenchymal stromal (SB623) cells. MCIDs for DRS, FM-UE, FM-LE, and FMMS were triangulated with distribution-based, anchor-based, and Delphi panel estimates. RESULTS Triangulated MCIDs were: 1) -1.5 points for the Disability Rating Scale; 2) 6.2 points for the Fugl-Meyer Upper Extremity Subscale; 3) 3.2 points for the Fugl-Meyer Lower Extremity Subscale; and 4) 8.4 points for the Fugl-Meyer Motor Scale. CONCLUSIONS For the first time in the setting of patients with chronic motor deficits secondary to TBI, this study reports triangulated MCIDs for: 1) DRS, a measure of global outcome; and 2) Fugl-Meyer Scales, measures of motor impairment. These findings guide the use of DRS and Fugl-Meyer Scales in the assessment of global disability outcome and motor impairment in future TBI clinical trials.

Abstract
Energy storage ceramics is among the most discussed topics in the field of energy research. A bibliometric analysis was carried out to evaluate energy storage ceramic publications between 2000 and 2020, based on the Web of Science (WOS) databases. This paper presents a detailed overview of energy storage ceramics research from aspects of document types, paper citations, h-indices, publish time, publications, institutions, countries/regions, research areas, highly cited papers, and keywords. A total of 3177 publications were identified after retrieval in WOS. The results show that China takes the leading position in this research field, followed by the USA and India. Xi An Jiao Tong Univ has the most publications, with the highest h-index. J.W. Zhai is the most productive author in energy storage ceramics research. Ceramics International, Journal of Materials Science-Materials in Electronics, and the Journal of Alloys and Compounds are the most productive journals in this field, and materials science—multidisciplinary is the most frequently used subject category. Keywords, highly cited papers, and the analysis of popular papers indicate that, in recent years, lead-free ceramics are prevalent, and researchers focus on fields such as the microstructure, thin films, and phase transition of ceramics.

Abstract
This study was designed to identify trends in the top-cited classic psychedelic publications. The top 50 publications on classic psychedelics with the greatest total of number of citations and annual citation rate were identified and pooled. Unique articles (n = 77) were dichotomized by median year of publication (2010); the differential distribution of study characteristics between the "Recent Cohort" (n = 40) and "Older Cohort" (n = 37) were documented. The Recent Cohort had a greater annual citation rate (median 76.5, IQR 43.8 to 103.3) compared to the Older Cohort (median 8.8, IQR 4.2 to 17.2, p < .001). The Recent Cohort included a greater number of clinical studies (n = 27 [67.5%] vs. n = 10 [27.0%]) while the Older Cohort included more basic science and preclinical studies (n = 22 [59.5%] vs. n = 3 [7.5%], p < .001). Psilocybin was the predominant psychedelic studied in the Recent Cohort (n = 26 [40.6%] vs. n = 8 [17.4%]) while lysergic acid diethylamide (LSD) was predominantly studied in the Older Cohort (n = 26 [56.5%] vs. n = 19 [29.7%], p = .028). The Recent Cohort included more studies examining affective disorders (n = 16 [25.8%] vs. n = 1 [2.7%]) and substance use disorders (n = 6 [9.7%] vs. n = 1 [2.7%]), while the Older Cohort included a greater number of pharmacological outcomes (n = 26 [70.3%] vs. n = 11 [17.7%], p < .001). This study identified and documented trends in the top-cited classic psychedelic publications. The field is continuing to form a foundational understanding of the pharmacological effects of psychedelics and is now advancing with the identification of therapeutic uses within clinical populations.

Abstract
Background: Radiosurgery is an effective, alternative treatment modality in managing patients with cerebral arteriovenous malformations (AVMs). The present study aims to highlight the scholarly impact of the top-100 most cited articles on the radiosurgical management of AVMs. Methods: A title-specific search using the keyword “arteriovenous malformation” was conducted in the Scopus database. The outcome of the search was rearranged based on the citations count. Articles were categorized into four entities; clinical, gamma knife radiosurgery, linear accelerator (LINAC) radiosurgery, and proton beam radiosurgery. The exclusion criteria were applied to spinal or non-intracranial AVM, conference papers, non-English articles predominantly discussing the endovascular or microsurgical management. Results: The top-100 articles on the radiosurgical management of AVM were published between 1972 and 2016. Approximately one-third of the publications were produced between 1995 and 2000. The average citations per year for all papers were seven. The most-studied entity was pertinent to the clinical application of gamma knife radiosurgery in AVM (68%). The United States was the most active country in studying the radiosurgical application in AVM. The Journal of Neurosurgery published approximately one-third of the most-cited articles in the list. The top-3 most contributing authors, publishing 80% of articles in the list, were Lunsford et al. Conclusion: The radiosurgical management of AVMs evolved significantly throughout the years. Identifications of the publication trends facilitate the acquisition of evidence-based articles for authors investigating various radiosurgical techniques in the treatment of AVMs.

Abstract
The aim of this article is to map the intellectual structure of scholarship on economic and social value in the sport industry. Given that bibliometric techniques are specially appropriate for identifying the intellectual structures of a field of knowledge and complement traditional literature reviews, a co-citation bibliometric analysis has been applied. This kind of analysis identifies networks of interconnections. Therefore, we aim to detect both the most and the least active research areas in this field, as well as their sub-disciplinary composition. There is an abundance of literature on sport efficiency and economic efficiency in the sport industry, our main conclusion is the identification of a literature gap in regard to social value in sport organisations, which is expected to be a research opportunity for scholars. This is in line with the lack of standardisation in the measurement for social value in sport organisations. In fact, similar to analysis undertaken in the past few decades of other industries with contributions to stakeholders and the multi-fiduciary theory of stakeholders, both the creation of social value indicators for sport entities and the empirical analysis of social efficiency in sport institutions, are identified and outlined as future areas of research. Therefore, this bibliometric analysis will contribute to determine the future challenges that this area of research will face in the following years so as to fill the literature gap identified.

Abstract
Objective The present study aimed to identify and analyze the bibliometric characteristics of the 100 top-cited studies on neuropsychology. Methods We searched the Web of Science Core Collection database to collect studies on neuropsychology from inception to 31st December 2019. Two authors independently screened the literature and extracted the data. Statistical analyses were performed using R software. Results The 100 top-cited articles were cited a total of 166,123 times, ranging from 736 to 24,252 times per article. All of the studies were published from 1967 to 2014 in 47 journals. Neuropsychologia had the highest number of articles (n = 17), followed by Neurology (n = 8). The top three most productive countries were the USA (n = 60), England (n = 13), and Canada (n = 8). Eight authors contributed the same number of studies as the first author (n = 2) or corresponding author (n = 2). The most productive institute was the University of California (n = 9), followed by the University of Pennsylvania (n = 4). Of the 100 top-cited publications, 64 were original articles, and 36 were reviews. The top three Web of Science categories were clinical neurology (n = 28), behavioral sciences (n = 19), and psychiatry (n = 11). Conclusion This study provides insight into the impact of neuropsychology research and may help doctors, researchers, and stakeholders to achieve a more comprehensive understanding of trends and most influential contributions to the field, thus promoting ideas for future investigation.

Abstract
Intimate partner violence (IPV) is a worldwide public health problem. Here, a bibliometric analysis is performed to evaluate the publications in the Intimate Partner Violence (IPV) field from 2000 to 2019 based on the Science Citation Index (SCI) Expanded and the Social Sciences Citation Index (SSCI) databases. This work presents a detailed overview of IPV from aspects of types of articles, citations, h-indices, languages, years, journals, institutions, countries, and author keywords. The results show that the USA takes the leading position in this research field, followed by Canada and the U.K. The University of North Carolina has the most publications and Harvard University has the first place in terms of h-index. The London School of Hygiene and Tropical Medicine leads the list of average citations per paper. The Journal of Interpersonal Violence, Journal of Family Violence and Violence Against Women are the top three most productive journals in this field, and Psychology is the most frequently used subject category. Keywords analysis indicates that, in recent years, most research focuses on the research fields of "child abuse", "pregnancy", "HIV", "dating violence", "gender-based violence" and "adolescents".

León Ruiz M, Benito-León J. The Top 50 Most-Cited Articles in Orthostatic Tremor: A Bibliometric Review. TREMOR AND OTHER HYPERKINETIC MOVEMENTS (NEW YORK, N.Y.) 2019; 9:tre-09-679. [PMID: 31413901 PMCID: PMC6691913 DOI: 10.7916/tohm.v0.679] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2019] [Accepted: 07/06/2019] [Indexed: 12/20/2022]
Abstract
Background Article-level citation count is a hallmark indicating scientific impact. We aimed to pinpoint and evaluate the top 50 most-cited articles in orthostatic tremor (OT). Methods The ISI Web of Knowledge database and 2017 Journal Citation Report Science Edition were used to retrieve the 50 top-cited OT articles published from 1984 to April 2019. Information was collected by the Analyze Tool on the Web of Science, including number of citations, publication title, journal name, publication year, and country and institution of origin. Supplementary analyses were undertaken to clarify authorship, study design, level of evidence, and category. Results Up to 66% of manuscripts were recovered from five journals: Movement Disorders (n = 18), Brain (n = 4), Journal of Clinical Neurophysiology (n = 4), Neurology (n = 4), and Clinical Neurophysiology (n = 3). Articles were published between 1984 and 2018, with expert opinion as the predominant design (n = 22) and review as category (n = 17). Most articles had level 5 evidence (n = 26). According to their countries of origin, 34% of articles belonged to the United States (n = 17) leading the list, followed by United Kingdom (n = 15). University College London yielded the greater number of articles (n = 12), followed by the University of Kiel (n = 9). Most popular authors were G. Deuschl (n = 10), C.D. Marsden (n = 6), J. Jankovic (n = 5), P.D. Thompson (n = 5), J.C. Rothwell (n = 5), L.J. Findley (n = 4), and P. Brown (n = 4), who together accounted for 48% of them. All papers were in English. Discussion Publishing high-cited OT articles could be facilitated by source journal, study design, category, publication language, and country and institution of origin.

Patterns, Types, and Outcomes of Head Injury in Aseer Region, Kingdom of Saudi Arabia. NEUROSCIENCE JOURNAL 2019; 2019:2782146. [PMID: 30984774 PMCID: PMC6431466 DOI: 10.1155/2019/2782146] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/25/2018] [Revised: 01/30/2019] [Accepted: 02/19/2019] [Indexed: 11/29/2022]
Abstract
Background Head injuries contribute to almost 50% of all injuries. Head injuries are still one of the major causes of loss of life and loss of function among young adults. Nowadays, head injury has become a major community problem. Recently, head injury has become one of the biggest issues of almost more than 57 million people in the whole world living with the neurological problem raised by TBI, in which 10 million people require hospital base care. Objectives To determine the epidemiological aspects of patients with head injury (HI) in Aseer Central Hospital (ACH). Materials and Methods This is a retrospective cross-sectional study. Data were gathered from patients' files and the registrar's database of ACH. The study duration was January 2015–December 2017. All patients with head injury admitted to ACH during the study duration were included in the study. SPSS software was used for analysis. Descriptive statistics were obtained (mean SD frequencies, percentages). Statistical tests, t test, and chi-squared test were applied to measure the significant difference among the variables. P-value less than 0.05 was considered as a significant difference. Results There were 353 patients with head injury, and the mean ± SD of age was 27.01 ± 13.9. Motor vehicle accidents (MVA) accounted for (89.3%) of head injury. A total of 87.3% of the patients were male while 12.7% were female. Conclusion In this study, we observed that MVA is the leading cause of brain/head injuries in the KSA, despite the implementations of new speed rules. However, with new regulations of forbidding cell phone use while driving and forcing the seat belt regulations, a major impact on these numbers is expected in the future. Thus, a future study is recommended to assess these expectations.

Abstract
Errors in neuron-microglial interaction are known to lead to microglial phagocytosis of live neurons and excessive neuronal loss, potentially yielding poorer clinical outcomes. Factors that affect neuron-microglial interaction have the potential to influence the error rate. Clinical comorbidities that unfavorably impact neuron-microglial interaction may promote a higher rate of neuronal loss, to the detriment of patient outcome. This paper proposes that many common, clinically modifiable comorbidities have a common thread, in that they all influence neuron-microglial interactions. Comorbidities like traumatic brain injury, infection, stress, neuroinflammation, loss of neuronal metabolic integrity, poor growth factor status, and other factors, all have the potential to alter communication between neurons and microglia. When this occurs, microglial phagocytosis of live neurons can increase. In addition, microglia can shift into a morphological form in which they express major histocompatibility complex II (MHC-II), allowing them to function as antigen presenting cells that present neuronal debris as antigen to invading T cells. This can increase risk for the development of CNS autoimmunity, or can exacerbate existing CNS autoimmunity. The detrimental influence of these comorbidities has the potential to contribute to the mosaic of factors that determine patient outcome in some CNS pathologies that have neuropsychiatric involvement, including TBI and CNS disorders with autoimmune components, where excessive neuronal loss can yield poorer clinical outcomes. Recognition of the impact of these comorbidities may contribute to an understanding of the common clinical observation that many seemingly disparate factors contribute to the overall picture of case management and clinical outcome in these complex disorders. In a clinical setting, knowing how these comorbidities can influence neuron-microglial interaction can help focus surveillance and care on a broader group of potential therapeutic targets. Accordingly, an interest in the mechanisms underlying the influence of these factors on neuron-microglial interactions is appropriate. Neuron-microglial interaction is reviewed, and the various mechanisms by which these potential comorbidities influence neuro-microglial interaction are described.

Abstract
Building on the seminal work by Geoffrey Harris in the 1970s, the neuroendocrinology field, having undergone spectacular growth, has endeavored to understand the mechanisms of hormonal connectivity between the brain and the rest of the body. Given the fundamental role of the brain in the orchestration of endocrine processes through interactions among neurohormones, it is thus not surprising that the structural and/or functional alterations following traumatic brain injury (TBI) can lead to endocrine changes affecting the whole organism. Taking into account that systemic hormones also act on the brain, modifying its structure and biochemistry, and can acutely and chronically affect several neurophysiological endpoints, the question is to what extent preexisting endocrine dysfunction may set the stage for an adverse outcome after TBI. In this review, we provide an overview of some aspects of three common metabolic endocrinopathies, e.g., diabetes mellitus, obesity, and thyroid dysfunction, and how these could be triggered by TBI. In addition, we discuss how the complex endocrine networks are woven into the responses to sudden changes after TBI, as well as some of the potential mechanisms that, separately or synergistically, can influence outcomes after TBI.

Abstract
PURPOSE It is unclear whether the muscular changes in mechanically-ventilated traumatic brain injury patients (TBI) are only associated with disuse or additionally to neuromuscular electrophysiological disorders (NED). The correlation between muscle atrophy and NED may affect functional outcomes and rehabilitation programs significantly. MATERIAL AND METHODS An observational study was performed to investigate the presence of NED and muscle atrophy in TBI patients undergoing mechanical ventilation. NED was diagnosed by the stimulus electrodiagnosis test when chronaxie was ≥1000μs. The muscle structure (thickness and echogenicity) was assessed by B-mode ultrasound. Tibialis anterior (TA), rectus femoris (RF), and biceps brachialis (BB) muscles were analyzed. Patients were followed from the first day of admission in the intensive care unit (ICU) to the fourteenth day. RESULTS Twenty-two patients were analyzed. An increase of 48% in NED from day 1 to day 14 was detected in TA (p=0.004). All muscles presented a significant decrease in thickness (~18%, p<0.05), but echogenicity increased only in TA (19%), p<0.01 and RF (23%), p<0.01. CONCLUSIONS Mechanically-ventilated patients with TBI developed NED in addition to changes in muscle structure during their stay in the ICU.

Abstract
The Glasgow Outcome Scale (GOS) was first published in 1975 by Bryan Jennett and Michael Bond. With over 4,000 citations to the original paper, it is the most highly cited outcome measure in studies of brain injury and the second most-cited paper in clinical neurosurgery. The original GOS and the subsequently developed extended GOS (GOSE) are recommended by several national bodies as the outcome measure for major trauma and for head injury. The enduring appeal of the GOS is linked to its simplicity, short administration time, reliability and validity, stability, flexibility of administration (face-to-face, over the telephone and by post), cost-free availability and ease of access. These benefits apply to other derivatives of the scale, including the Glasgow Outcome at Discharge Scale (GODS) and the GOS paediatric revision. The GOS was devised to provide an overview of outcome and to focus on social recovery. Since the initial development of the GOS, there has been an increasing focus on the multidimensional nature of outcome after head injury. This Review charts the development of the GOS, its refinement and usage over the past 40 years, and considers its current and future roles in developing an understanding of brain injury.

Abstract
PURPOSE The objective of this study was to identify and review the most-cited articles on spinal cord injury (SCI). Citation analyses showcase the relative influence of individual articles in a given field. In addition to distinguishing publications of particular quality and impact and well-developed areas of the literature, citation analyses allow for an understanding of the direction in which a field of research is headed. METHODS A multi-disciplinary bibliographic index was used to identify the 50 SCI articles with the most lifetime citations, and the 50 SCI articles with the highest annual citation rates. Studies were categorized into one of six categories based on their primary focus: treatment, pathology/natural history, predictor of outcome, methods, epidemiology, or assessment measure. RESULTS We report that 40.0 and 56.0 % of SCI papers with the most lifetime citations and highest annual citation rates, respectively, were systematic reviews or meta-analyses, indicating that some of the most referenced papers in SCI are not primary publications. Further, there appears to be a greater international presence in SCI research. In the highest annual citation rate cohort, 14.0 % of papers were a product of international collaboration, 50.0 % were published by outside of the United States, and the average year of publication was 2005 ± 5.4; the comparable numbers for papers that comprised the highest lifetime citation cohort were, respectively, 8.0, 28.0 %, and 1998 ± 9.2. Treatment and pathology/natural history of SCI were a common research focus in both citation cohorts, consistent with ongoing efforts to better understand and manage this injury. CONCLUSIONS This comprehensive review provides a cross-sectional summary and bibliometric analysis of some of the most influential literature in SCI, and compliments existing systematic reviews and meta-analysis in the field by establishing which areas of the literature are growing and which have been well developed.

Abstract
Bibliometric studies, which involve the use of statistical methods, are increasingly being used for research assessment. A bibliometric analysis was conducted to evaluate the publication pattern of methaemoglobinaemia research output at the global level based on the Scopus database. We analysed selected documents with "methemoglobinemia", or "methaemoglobinaemia" as a part of the title and reported the following parameters: trends of publication output, country of publication, journal pattern, collaborative measures, citations pattern, and institute productivity. A total of 1770 articles were published worldwide. The time trend for the number of articles showed an increase after 2000. The highest number of articles related to methaemoglobinaemia was from the USA (24.8 %), followed distantly by the UK (4.5 %), India (3.7 %), and France (3.7 %). No data related to methaemoglobinaemia were published from 152 countries. The total number of citations at the date of data collection was 10,080, with an average of 5.7 citations per document. The USA and UK had the highest h-index of 31 and 14, respectively, and six countries had an h-index of 9-14. It is notable that Canada was ranked eighth in the number of publications but fourth in h-index and India was ranked third in the number of publications but eighth in h-index. Furthermore, Canada produced the most internationally collaborated papers out of the total number of publications for each country (16.1 %), followed by the UK (13.9 %). This bibliometric analysis provides data contributing to a better understanding of the methaemoglobinaemia research field. The number of publications on methaemoglobinaemia increased significantly after 2000. The USA was the most productive country as measured by total publications. The USA and UK achieved the highest h-index in the field of methaemoglobinaemia research, signifying a higher quality of research than other countries.

Abstract
BACKGROUND China, as a rapidly developing country with the largest population of cardiologist in the world, has an increasing importance in the field of cardiology. However, the quantity and quality of research production in the field of cardiology is unclear. AIMS To analyze the characteristics of the high-level articles published on cardiovascular diseases in Mainland China, and to provide information about achievements and development in cardiovascular research. METHODS We searched the Science Citation Index Expanded for citations of cardiovascular articles originating in mainland China from 2004 to 2015. For the 100 most frequently cited articles (T100), we evaluated the number of citations, publication time, province of origin, journal, impact factor, topic or subspecialty of the research, and publication type. RESULTS The most frequently cited article received 703 citations at the most, while 50 at the least (mean 91.6 citations per article). T100 originated from 16 provinces, the plurality (n = 34) being from the Beijing. Sixty-seven percent were published during 2006-2009. The publications were in 29 different journals of which Circulation published the most (n = 14). Leading general medical journals Journal of the American Medical Association (n = 1), Lancet (n = 0) and New England Journal of Medicine (n = 0) featured only 1 published article, despite their extremely high impact factors. Of the T100 articles, there were 50 basic researches, 44 clinical researches, 5 meta-analyses and 1 review article. Clinical researches had the highest mean citations (mean 102.6 citations per article). CONCLUSIONS This study provides a historical perspective on the scientific progress, and the trends in cardiovascular medicine in Mainland China.

Abstract
BACKGROUND Knowledge of the epidemiology of traumatic brain injury (TBI) is required both to prevent this disorder and to develop effective care and rehabilitation approaches for patients. OBJECTIVE The aim of this article is to find solutions to decrease the incidence of TBI and offer recommendations for their prevention. MATERIAL AND METHODS We analyzed epidemiological studies on TBI by performing a systematic review of literature, using information reported by different centers, collecting data on demographics, showing characteristics of TBI including incidence, identification of risk groups on differences in age, gender, geographical variation, severity and mortality. RESULTS Studies suggest that the incidence of TBI is between 18 and 250 per 100,000 persons per year. Men and people living in social and economical deprived areas, usually young adults and the elderly are high-risk groups for TBI. DISCUSSION Prevention remains the "key point" in medicine and especially for TBI, saving the patient from unnecessary often-harsh sufferance. CONCLUSIONS Most public epidemiological data showed that TBI is a major cause of mortality and disability. The effort to understand TBI and the available strategies to treat this lesion, in order to improve clinical outcomes after TBI, may be based on an increase in research on the epidemiology of TBI. A coordinated strategy to evaluate this public health problem in Romania would first of all rely on a related advanced monitoring system, to provide precise information about the epidemiology, clinical and paraclinical data, but concerning the social and economic connected consequences, too.
