ABSTRACT Objective: To provide an analysis of the 50 most cited articles on knee surgery in the Brazilian medical literature. Methods: This is a study of systematic review and meta-analysis, level of evidence 3. It was carried out through search in the SCOPUS database to identify scientific articles published in the Brazilian medical literature. Eighty-six Brazilian journals were analyzed, and articles with ten or more citations and which had the word “joelho” or “knee” in the title, abstract or keywords were selected. Results: All articles were published as of the year 2000 in 14 journals. The Journal Clinics presented the largest number of publications, followed by Acta Ortopédica Brasileira. The main focus of the studies was on anatomy and biomechanics, mainly from Brazilian authors. Most of the authors were Brazilian, from Brazilian and public research institutions. Conclusion: Biometric analysis has been gaining ground in recent years, but its interpretation must consider various aspects related to the paramount analytical importance.

The aim of this work is to study the state of current research in the field of politics and AI. Our research question is about the possibility of using artificial intelligence in order to run political judgments. The main problem of researching artificial intelligence deals with the value-based biases of judgments about the present and the future of these technologies. The article uses the meta-analysis method, which in recent years has become quite widespread in the specialized literature. The article provides an overview of the most cited publications in the Scopus database with the keywords “Artificial Intelligence” and “Politics”. In total, the study has included 76 articles and reports that were indexed by the database over the past 20 years. It is concluded that in recent years there has been a trend towards an increase in the number of publications on the problems of artificial intelligence and politics. However, most of them are only indirectly related to the central problems of political science. The study of the topic of artificial intelligence most closely adjoins the study of the problems of big data and political communication in social networks.

ABSTRACT The aim of this study was to analyze the scientific production of journals on sport and exercise science and physical education in Portuguese that are indexed in the Scopus database by conducting a bibliometric analysis. Six journals related to this field of study and indexed in the Scopus database were selected. Regarding publications, the journals published 3,869 documents while indexed in Scopus, most (90.8%) of which were original articles. The year with the highest number of publications was 2013 (n = 473). The clusters of keywords that were cited most often (“physical activity” and “exercise”) were related to biodynamics. Most journal authors are from Brazil (89.86%). The Brazilian Journal of Sports Medicine had the highest number of publications (n = 1179), the highest average per year (n = 78.6), and reached the highest index in the scientific journal ranking (SJR index = 0.331). We concluded that scientific production increased until 2013. The publications with the highest number of citations and the most common study topics are related to the area of biodynamics.

Distal Realignment

AbstractDistal realignment procedures are now commonly performed routinely with proximal realignment procedures. Despite so, only a limited number of publications exist that have looked into the efficacy of isolated distal realignment procedures, and whether there is indeed a need for routine proximal realignment procedures to be added to the distal realignment procedures. The current systematic review and meta-analysis aims to evaluate the outcomes of isolated distal realignment procedures in the management of patellofemoral instability. The review was conducted using the preferred reporting items for systematic reviews and meta-analyses (PRSIMA) guidelines. All studies that reported the outcomes of isolated distal realignment procedures for patellofemoral instability were included. A total of six publications were included, with 347 knees. All studies consistently reported a decrease in the rates of patellofemoral instability or maltracking (odds ratio [OR]: < 0.01; 95% confidence interval [CI]: < 0.01–0.01) and an increase in the odds of having a good outcome (OR: 0.01; 95% CI: < 0.01–0.02) after distal realignment procedures. A total of 24 out of 306 patients (7.8%) had postoperative instability or maltracking, and a total of 220 out of 303 patients (72.6%) were rated to have good or excellent outcomes postoperatively. Isolated distal realignment procedures can lead to good outcomes when used in the management of patellofemoral instability. These include a significantly decreased rate of patellofemoral instability or maltracking and a significantly increased number of patients with excellent or good outcomes postoperatively. Comparisons between patients with and without additional proximal realignment procedures suggest that additional proximal realignment procedures do not definitely improve the outcomes of distal realignment procedures and, therefore, should not be routinely performed in all patients undergoing distal realignment procedures. The Level of Evidence for this study is IV.

Abstract Purpose Arthroscopy is an established sub-speciality in orthopaedics. With advancing technology, instrumentation and implants, this sub-speciality has seen an explosion of knowledge and techniques since its inception. The indications for arthroscopic management are increasing and, hence, the number of publications on this topic. There has been no study looking into the bibliometrics of all publications within this speciality. The purpose of this study was to look into the trends of published articles on arthroscopy from PubMed and Scopus including studying their citation numbers. Materials and methods We set out to look into the number of publications from the earliest up to 2019 and their trends and citation numbers in PubMed and Scopus. We also performed a VOS viewer analysis of MeSH terms and titles of publications to look at research trends over time. Results There were 41,149 articles published on PubMed since 1955 and 50,373 articles on Scopus since 1939. The total number of citations were 912,630 for 38,338 cited articles. With 2864 publications in 2019, there was a more than four-fold increase from the number published in the year 2000. The knee joint was the most frequently published joint with an increasing trend in hip arthroscopy. Cohort studies were the most common with 13,180 articles followed by Reviews with 5746 articles. The top 10 authors, universities and journals were listed along with citation numbers. We analysed the trends of publications for each joint and compared them. Yearly citations have progressively increased to reach a maximum of 45,407 in 2007. Arthroscopy was the most published and cited journal on this topic. The Journal of Bone and Joint Surgery (JBJS) (Am) had the most citations per article. The USA and Hospital for Special Surgery, New York were the most published country and university, respectively. Conclusions There is a healthy growth of publications on the subject of arthroscopy with a steep increase in the number of publications and citations in recent years. VOS Viewer analysis showed an evolution of research and practice in the field of arthroscopy. Recommendations were made for databases and search engines to improve on the search and analysis of such studies in the future. Level of evidence 4

Background: The sole objective of the present study is to explore the research trends in photocatalysis. Materials and Methods: In this area, the first document was published in the year 1921 and untill August 2020, a total of 6940 documents are archived in Scopus database. Results and Discussion: Its worthy to note that after 2000 a remarkable increase in publications has been noticed. Infact 6605 articles are published after 2000. The highest number of publications are reported in 2019 (784/11.87% of 6605) followed by 2018 (740/11.20% of 6605) and 2017 (624/9.45% of 6605). We calculated the per year growth rate and doubling time of publications. In research publications, the top three (3) countries are China (3030/43.65%), USA (704/10.14%) and India (503/7.24%). We provided the details which may explain, why China is the global leader in photocatalysis research. Furthermore, by Vosviewer analysis we provided the co-authorship and citations details of only research articles and reviews (total 6197 documents). Based on the (a) number of publications and (b) citations, the list of top ten (10) authors, institutes, countries and sources details are provided. We also performed the Vosviewer analysis for China’s publications (n=3030)The details about the top authors, institutes and collaborative countries are provided. One of the fundamental question is; what has been covered in photocatalysis research articles and reviews (n=6197)? For the purpose, we manually analyzed 47,722 keywords and grouped them in different categories. Conclusion: Mostly the document covered research under the names of photocatalysis, semiconductors, photochemical sources, instrumental techniques, electrochemistry, nanomaterials and water treatment. We extended the idea and explored the research publications in selected semiconductors (like titanium, graphene, cadmium, bismuth and iron based compounds), water purification, toxic pollutants, photcatalytic reduction of carbon dioxide, nanomaterials and certain specific instruments like SEM, TEM & XRD etc.

Bibliometric analysis of 3105 publications retrieved from the Scopus database was conducted to evaluate bibliographic content of scientific output on social sciences in Vietnam, for the 2000–2019 period. Our main findings show that the number of publications on social sciences from Vietnam has increased significantly over the last two decades, and there was a spike in the scientific output for the recent three years when the number of publications accounted for 53.76% of the collection. The most productive authors came from a few public research institutes with strong resources as the top 10 institutions participated in 44.22% of the collection. Vietnamese scholars tend not to submit their works to high-ranking journals since five Q1 journals in the top 10 publishing journals published only 6.17% of the collection. For international collaboration, Australia and the United States ranked first and second based on the number of publications and citations. Other countries in top 10 mostly located in Europe and Asia. Research topics were diverse focusing on gender, poverty, HIV, higher education and sustainable development. We suggest that supporting policies and funding need to be provided to help Vietnamese scholars improve their works, and to boost their scientific production in the future.

Abstract Background Entero-colovesical fistula is a rare complication of various benign and malignant diseases. The diagnosis is prominently based on clinical symptoms; imaging studies are necessary not only to confirm the presence of the fistula, but more importantly to demonstrate the extent and the nature of the fistula. There is still a lack of consensus regarding the if, when and how to repair the fistula. The aim of the study is to review the different surgical treatment options, focus on surgical indications, and explore cumulative recurrence, morbidity, and mortality rates of entero-vesical and colo-vesical fistula patients. Methods A systematic review of the literature was conducted according to PRISMA guidelines. Random effects meta-analyses of proportions were developed to assess primary and secondary endpoints. I2 statistic and Cochran’s Q test were computed to assess inter-studies’ heterogeneity. Results Twenty-two studies were included in the analysis with a total of 861 patients. Meta-analyses of proportions pointed out 5, 22.2, and 4.9% rates for recurrence, complications, and mortality respectively. A single-stage procedure was performed in 75.5% of the cases, whereas a multi-stage operation in 15.5% of patients. Palliative surgery was performed in 6.2% of the cases. In 2.3% of the cases, the surgical procedure was not specified. Simple and advanced repair of the bladder was performed in 84.3% and 15.6% of the cases respectively. Conclusions Although burdened by a non-negligible rate of complications, surgical repair of entero-colovesical fistula leads to excellent results in terms of primary healing. Our review offers opportunities for significant further research in this field. Level of Evidence Level III according to ELIS (SR/MA with up to two negative criteria).

Context: Despite growing interest in quantifying and correcting vitamin D inadequacy in basketball players, a critical synthesis of these data is yet to be performed to overcome the low generalizability of findings from individual studies. Objective: To provide a comprehensive analysis of data in basketball pertaining to (1) the prevalence of vitamin D inadequacy; (2) the effects of vitamin D supplementation on 25-hydroxyvitamin D [25(OH)D] concentration (and its association with body composition), bone health, and performance; and (3) crucial aspects that warrant further investigation. Data Sources: PubMed, MEDLINE, ERIC, Google Scholar, SCIndex, and ScienceDirect databases were searched. Study Selection: After screening, 15 studies were included in the systematic review and meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 3. Data Extraction: The prevalence of vitamin D inadequacy, serum 25(OH)D, body composition, stress fractures, and physical performance were extracted. Results: The pooled prevalence of vitamin D inadequacy for 527 basketball players in 14 studies was 77% ( P < 0.001; 95% CI, 0.70-0.84). Supplementation with 4000 IU/d and 4000 IU/wk (absolute mean difference [AMD]: 25.39 nmol/L; P < 0.001; 95% CI, 13.44-37.33), as well as 10,000 IU/d (AMD: 100.01; P < 0.001; 95% CI, 70.39-129.63) vitamin D restored 25(OH)D to normal concentrations. Body composition data revealed inverse correlations between changes in serum 25(OH)D (from pre- to postsupplementation) and body fat ( r = −0.80; very large). Data concerning positive impacts of vitamin D supplementation on bone health and physical performance remain sparse. Conclusion: The high proportion of vitamin D inadequacy underscores the need to screen for serum 25(OH)D in basketball players. Although supplementation restored vitamin D sufficiency, the beneficial effects on bone health and physical performance remain sparse. Adiposity can modulate 25(OH)D response to supplementation.
