Determine the bibliometric characteristics of scientific articles that address the subject of neurosurgery in Latin America and the Caribbean. 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. 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. 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. [ABSTRACT FROM AUTHOR]

Background: Giardia spp. is the most common protozoan found in coproparasitoscopic tests; it is the cause of gastrointestinal discomfort, with a high prevalence in children and in low-income areas. This systematic review updates available literature on molecular identification of Giardia spp. in Latin America during 2017 to 2021. Methodology: The guidelines established in Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used; the study covers the period from January 1, 2017 to October 03, 2021; the search focused on the "molecular identification of Giardia spp. in Latin America" in six different scientific databases. The material found was reviewed to select only those papers that met the inclusion and exclusion criteria. Results: The search yielded 1036 publications, but only 19 investigations in 6 countries (Brazil, Colombia, Cuba, Ecuador, Mexico, and Venezuela) met the selection criteria. Most were cross-sectional studies carried out in school-age children, the dominant assemblages were A and B while the most frequent subassemblages were AII, BIII and BIV, the most used target genes were tpi and gdh, the prevalence by molecular methods was higher regarding microscopy, the countries with the highest prevalence percentages for Giardiosis were Brazil and Cuba. Conclusions: More Latin America countries need to generate data of prevalence, incidence, and intensity of Giardiosis. Studies are also needed to estimate the costs of Giardiosis on economic productivity and public health. The present systematic review offers evidence based on the current literature available for the molecular identification of Giardia spp. in Latin America during 2017 to 2021. [ABSTRACT FROM AUTHOR]

Bibliometrics is a scientific discipline that studies quantitatively the bibliographic material of a particular topic. This study analyzes management research published by Latin American countries between 1990 and 2019. The work uses the Web of Science database and provides several country-level bibliometric indicators including the total number of publications and citations, and the h-index. The results indicate that Brazil, Chile and Mexico have constantly led the region's scientific publications. The temporal evolution shows a significant increase on the number of publications during the last years that seems to continue in the future. The results also show that operations research and finance are the most significant topics in the region. [ABSTRACT FROM AUTHOR]

Background: Global opioid consumption increased multifold post-2000, disproportionately in high-income countries, with severe mortality/morbidity consequences. Latin America features comparatively low opioid availability; Brazil, the region's most populous country, makes an interesting case study concerning opioid use/harms. In this comprehensive overview, we aimed to identify and summarize medical and non-medical data and indicators of opioid availability and use, regulation/control, and harm outcomes in Brazil since 2000.Methods: We searched multiple scientific databases to identify relevant publications and conducted additional 'grey' literature searches to identify other pertinent information.Results: Despite some essential indicators, opioid-related data are limited for Brazil. Data indicate that population-level availability of prescription opioids represents only a small fraction of use in comparison to high-income countries. However, within Latin America, Brazil ranks mid-level for opioid consumption, indicating relatively moderate consumption compared to neighboring jurisdictions. Brazil has implemented restrictive regulations to opioid prescribing and is considered 'highly restricted' for opioid access. Codeine remains the major opioid analgesic utilized, but stronger opioids such as oxycodone are becoming more common. Professional knowledge regarding medical opioid use and effects appears limited. National surveys indicate increases in non-medical use of prescription opioids, albeit lower than observed in North America, while illicit opioids (e.g., heroin) are highly uncommon.Conclusions: Overall population-level opioid availability and corresponding levels of opioid-related harms in Brazil remain substantially lower than rates reported for North America. However, the available surveillance and analytical data on opioid use, policy/practice, and harms in Brazil are limited and insufficient. Since existing and acute (e.g., pain-related) needs for improved opioid utilization and practice appear to be substantiated, improved indicators for and understanding of opioid use, practice, and harms in Brazil are required.
