World Neurosurg 2022; 165:e401-e411. [PMID: 35724879 DOI: 10.1016/j.wneu.2022.06.064] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 06/13/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVES Determine the bibliometric characteristics of scientific articles that address the subject of neurosurgery in Latin America and the Caribbean. METHODS A bibliographic search of original articles published in the Web of Science database up to 2021 was performed, without language restrictions. The terms included in the search strategy were Neurosurgery, neurosurgical procedures, and neurological surgical procedure. Articles according to the inclusion criteria in the Rayyan application were included. Subsequently, a quantitative bibliometric analysis was carried out with the bibliometrix package in R and VOSviewer. RESULTS We identified 882 articles published in 271 journals. The first publication was in 2006, the highest number of publications was in 2021, the annual percentage growth rate was 25.9, and the average number of citations per document was 11.2. The author with the highest number of publications was Teixeira MJ (41 articles), and the University of Sao Paulo had the highest number of articles on this topic. WORLD NEUROSURGERY was the journal with the most publications (120 articles), and the study by Carney et al (2017) was the most cited (1175 citations). The country of corresponding authors with the most publications and the greatest number of total citations was Brazil. Surgery, and Management were the most used keywords plus; however, in the most recent articles Simulation and Guidelines were used. CONCLUSIONS In the past decade, there has been an increase in articles on neurosurgery in Latin America and the Caribbean. Scientific production in neurosurgery must continue to increase in order to promote evidence-based medicine.

Ramos MB, Rech MM, Dagostini CM, Britz JPE, Teixeira MJ, Figueiredo EG. The Author Impact Factor as a Metric to Evaluate the Impact of Neurosurgical Researchers. World Neurosurg 2022; 165:e74-e82. [PMID: 35636666 DOI: 10.1016/j.wneu.2022.05.100] [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: 04/18/2022] [Accepted: 05/21/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVE The objective of this study was to assess the Author Impact Factor (AIF) as a useful metric and as a complement to the h-index among neurosurgical researchers. METHODS The 5-year AIF and h-index were compared among 3 groups of researchers: 1) the 100 most prolific of all time within general neurosurgical journals ("Experienced"), 2) the 100 most prolific during the 2015-2019 period within general neurosurgical journals ("Trending Group"), and 3) the 100 postgraduation year 7 neurosurgical residents with the highest h-index ("Amateur"). RESULTS The Amateur group had a lower median h-index than the Experienced (6 vs. 55; P < 0.001) and Trending (6 vs. 43; P < 0.001) groups. The highest h-index of the Amateur group (24) was lower than the first quartile of the Experienced (46.25) and Trending (26.00) groups. The Amateur group had a lower median 5-year AIF than the Experienced (2.15 vs. 3.17; P < 0.001) and Trending (2.15 vs. 2.85; P = 0.02) groups. Unlike the h-index, the gap between the 5-year AIF distribution of the Amateur group and other groups was not profound. Although there was a positive correlation between the metrics in the 3 groups, they did not proxy for each other. For instance, while the h-index of some experienced authors that have not published recently was high, their AIFs were zero. Also, some Amateur authors published very impactful articles and had a high 5-year AIF. However, since their number of publications is inevitably low, their h-index were low. CONCLUSIONS The AIF provides intuitive and complementary information to the h-index regarding the research output of neurosurgical authors.

The Application of Guideline-Based Care for Traumatic Brain and Spinal Cord Injury in Low- and Middle-Income Countries: A Provider-Based Survey. World Neurosurg X 2022; 15:100121. [PMID: 35515346 PMCID: PMC9061784 DOI: 10.1016/j.wnsx.2022.100121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Accepted: 03/04/2022] [Indexed: 11/22/2022] Open
Abstract
Objective Neurosurgical guidelines have resulted in improved clinical outcomes and more optimized care for many complex neurosurgical pathologies. As momentum in global neurosurgical efforts has grown, there is little understanding about the application of these guidelines in low- and middle-income countries. Methods A 29-question survey was developed to assess the application of specific recommendations from neurosurgical brain and spinal cord injury guidelines. Surveys were distributed to an international cohort of neurosurgeons and neurotrauma stakeholders. Results A total of 82 of 222 (36.9%) neurotrauma providers responded to the survey. The majority of respondents practiced in low- and middle-income countries settings (49/82, 59.8%). There was a significantly greater mean traumatic brain injury volume in low-income countries (56% ± 13.5) and middle-income countries (46.5% ± 21.3) compared with high-income countries (27.9% ± 13.2), P < 0.001. Decompressive hemicraniectomy was estimated to occur in 61.5% (±30.8) of cases of medically refractory intracranial pressure with the lowest occurrence in the African region (44% ± 37.5). The use of prehospital cervical immobilization varied significantly by income status, with 36% (±35.6) of cases in low-income countries, 52.4% (±35.5) of cases in middle-income countries, and 95.2% (±10) in high-income countries, P < 0.001. Mean arterial pressure elevation greater than 85 mm Hg to improve spinal cord perfusion was estimated to occur in 71.7% of cases overall with lowest occurrence in Eastern Mediterranean region (55.6% ± 24). Conclusions While some disparities in guideline implementation are inevitably related to the availability of clinical resources, other differences could be more quickly improved with accessibility of current evidence-based guidelines and development of local data.

Global Research Status and Trends of Femoral Neck Fracture Over the Past 27 Years: A Historical Review and Bibliometric Analysis. Front Surg 2022; 9:875040. [PMID: 35784942 PMCID: PMC9241583 DOI: 10.3389/fsurg.2022.875040] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Accepted: 05/20/2022] [Indexed: 11/24/2022] Open
Abstract
Background Femoral neck fracture (FNF) is a commonly encountered injury in orthopedic practice, and many studies have been conducted in this field. However, no bibliometric studies regarding the global research trend concerning FNF have been performed. This study aims to analyze the knowledge framework, research hotspots, and theme trends in the field of FNF research. Methods The scientific outputs related to FNF from 1994 to 2021 were retrieved from the Web of Science Core Collection. Three bibliometric tools were used for this study. The main analyses include publication and citation counts, contributions of countries, institutions, authors, funding agencies and journals, and clustering of keywords. Results In total, 3,553 articles were identified. The annual publication counts of FNF showed an ascending tendency as a whole. The United States has the most prominent contributions, with the most number of publications and the highest H-index. Karolinska Institutet devoted the most in this domain. Professors Bhandari M, Schemitsch EH, Frihagen F, Parker MJ, and Rogmark C were the core authors in this field. The most productive journal was Injury International Journal of the Care of the Injured. Keywords were divided into four clusters: epidemiology and mortality, fracture prevention, internal-fixation and risk factors, and hip replacement. A trend of balanced and diversified development existed in these clusters. Keywords with the ongoing bursts, including “outcome,” “reoperation,” “complication,” “revision,” “displaced intracapsular,” “fracture,” and “adult,” are considered as the research hotspots in the future and deserve more attention. Conclusions The management of FNF in young patients is drawing more attention from orthopedic surgeons, and it is expected that these research topics may continue to be the research hotspots and focus in the near future.

Abstract
BACKGROUND Following total knee arthroplasty (TKA), postoperative patient rehabilitation is important to achieve the optimal level of knee function and mobility. Clinical research in this field is growing, and bibliometric analysis of publication may provide direction for research clinicians and raise awareness of research trends, journal selection, and key topics. Therefore, this bibliometric study aimed to analyze the current status and trends during the past two decades, between 1999 and 2018, of publications on rehabilitation after total knee arthroplasty (TKA) and used CiteSpace. MATERIAL AND METHODS The global literature was searched between 2018 to 2019 for publications related to rehabilitation after TKA. Publication data were identified using relevant search terms and the Web of Science Core Collection database. CiteSpace (5.3.R11) software was used to analyze the journals, authors, institutions, countries, cited references, and keywords using standard bibliometric indicators. RESULTS A total of 1,292 publications were retrieved between 1999 to 2018, and the most active journals, countries, authors, and institutions in the field of TKA rehabilitation were identified. Key areas of research included postoperative analgesia, muscle inhibition, range of motion, inhibitors, knee flexion, pain control, self-reporting, spectral analysis, in vivo forces, and rotator cuff repair. The emerging research topics included epidural analgesia, physiotherapy, postoperative analgesia, recovery, and the use of ropivacaine local analgesia. CONCLUSIONS The findings from this bibliometric study provided insight into trends in clinical research publications in the field of rehabilitation following TKA for the past 20 years, including global trends in emerging areas of research.
