The Impact

Bibliometric analyses of the hand and wrist research have previously shown a significant increase in research productivity in Asia. We examined the key contributors to this change by performing bibliometric analyses regarding hand and wrist research in all Asian countries producing significant research. Original research articles from 1988 to 2007 were collected from seven English language journals based on the impact factor. Trends in research productivity were determined by country using linear regression analysis. Compared to the rest of the world, Asia produced fewer level I and basic studies, but more level IV studies. Significant increase in both research volume and productivity in Asia was observed, with Japan, Korea, and Taiwan having the highest aggregate productivity in hand and wrist research. From 1988 to 2007, the relative research production among Asian countries showed significant change, in contrary to that of Europe, Latin American, and the United States.

Bibliometric analyses, which study trends in research productivity, have not previously been applied to hand and wrist research. This study analyses temporal and geographic trends in hand and wrist research from 1988 to 2007. Original research articles were collected from seven English language journals selected on the basis of impact factor. Research production and quality (level of evidence) were determined by country and global region. Linear regression analysis was used to investigate trends. No significant increase in research volume was observed, but journal impact factors have risen significantly since 1988. Western Europe contributed significantly more high-quality (Level I and II) studies than the United States. Research contributions show a geographical distribution concentrated in the US and Western Europe, but considerable changes in this distribution have occurred. From 1988 to 2007, there was a relative increase in research production from Europe, Latin America and Asia, and a relative decline from the US.

Abstract Objective: The citation history of a published article reflects its impact on the literature over time. We conducted a comprehensive bibliometric analysis to identify the most cited papers on CHD in children. Methods: One-hundred and ninety journals listed in Journal Citation Reports were accessed via Web of Science. Publications with 250 or more citations were identified from Science Citation Index Expanded (1900–2020), and those relating to structural CHD in children were reviewed. Articles were ranked by citation count and the 100 most cited were analysed. Results: The number of citations ranged from 2522 to 309 (median 431, IQR 356–518), with 35 published since 2000. All were written in English, most originated from the United States (74%), and were published in cardiovascular journals, with Circulation (28%) the most frequent. There were 86 original research articles, including 50 case series, 14 cohort studies, and 10 clinical trials. The most cited paper was by Hoffman JI and Kaplan S on the incidence of CHD. Thirteen authors had 4 or more publications in the top 100, all of whom had worked in Boston, Philadelphia, San Francisco, or Dallas, and the most prolific author was Newburger JW (9 articles). Conclusions: Citation analysis provides a historical perspective on scientific progress by assessing the impact of individual articles. Our study highlights the dominant position of US-based researchers and journals in this field. Most of the highly cited articles remain case series, with few randomised controlled trials in CHD appearing in recent years.

Abstract BACKGROUND The incidence of spina bifida (SB) in the developing world is higher than in the United States because of malnutrition and folic acid deficiency during pregnancy. Advances in technology have made prenatal repair of myelomeningocele (MM) possible. OBJECTIVE The objective of the guidelines are, (1) To create clinical recommendations for best practices, based on a systematic review and analysis of available literature, (2) to obtain multi-disciplinary endorsement of these guidelines from relevant organizations, and (3) to disseminate the educational content to physicians to improve the care of infants with MM. METHODS The Guidelines Task Force developed search terms and strategies used to search PubMed and Embase for literature published between 1966 and September 2016. Strict inclusion/exclusion criteria were used to screen abstracts and to develop a list of relevant articles for full-text review. RESULTS Guidelines authors aimed to systematically review the literature and make evidence based recommendations about the timing of closure after birth, hydrocephalus, the impact of prenatal closure, and the effect of prenatal closure on ambulation ability and tethered spinal cord. Evidence concerning persistent ventriculomegaly and cognitive impairment was also evaluated. Hundreds of abstracts were identified and reviewed for each of the 5 topics. A total of 14 studies met stringent inclusion criteria. CONCLUSION Based on a comprehensive systematic review, a total of 5 clinical practice recommendations were developed, with 1 Level I, 2 Level II and 2 Level III recommendations.

ABSTRACT Background The nutritional profile of human milk varies significantly between women, and the impact of maternal diet on these variations is not well understood. Objective We analyzed breast-milk vitamin B-12 concentration and vitamin B-12 supplement use pattern among women who adhered to different dietary patterns: vegan, vegetarian, and nonvegetarian. Design A total of 74 milk samples, 29 from vegan, 19 from vegetarian, and 26 from nonvegetarian breastfeeding mothers, were analyzed. Results The prevalences of low vitamin B-12 (<310 pmol/L) were 19.2% for vegans, 18.2% for vegetarians, and 15.4% for nonvegetarians, which was not significant by diet group (P = 1.00). The median (quartile 1, quartile 3) vitamin B-12 values were 558 pmol/L (331, 759 pmol/L) for vegans, 509 pmol/L (368, 765 pmol/L) for vegetarians, and 444 pmol/L (355, 777 pmol/L) for nonvegetarians (P = 0.890). The use of individual vitamin B-12 supplements was higher in vegans (46.2%) than in vegetarians (27.3%) and nonvegetarians (3.9%) (P = 0.001). In linear regression analysis, the use of individual vitamin B-12 supplements was a significant positive predictor of milk vitamin B-12 concentration (β ± SE: 172.9 ± 75.2; standardized β = 0.263; P = 0.024; R2 = 0.069), the use of a multivitamin had a significant negative relation with milk vitamin B-12 concentrations (β ± SE −222.0 ± 98.7; standardized β = −0.258; P = 0.028, R2 = 0.067;), whereas the use of a B-complex vitamin and prenatal vitamin were not predictive of vitamin B-12 milk concentration (P > 0.05). Conclusions Almost 20% of our study participants were classified as having low breast-milk vitamin B-12 concentrations (<310 pmol/L), independent of maternal diet pattern. Approximately 85% of participants categorized as having low vitamin B-12 were taking vitamin B-12 supplements at doses in excess of the Recommended Dietary Allowance, which suggests that more research is needed to determine breast-milk adequacy values.

On May 24, 1965, nearly a month after the first U. S. Marines landed in Santo Domingo, an inter-American military force under the command of a Brazilian general took over peacekeeping activities in the Dominican Republic. Although the first Brazilian contingent to arrive comprised only 300 troops, it later reached a total of 1,250, the largest contribution by a single Latin American nation. While Brazil's participation in the Dominican crisis was a clear indication that the independent foreign policy of Quadros and Goulart had been discarded in favor of a realignment once again with the United States, it also signified an abrupt departure from one of the basic tenets of Brazilian foreign policy—nonintervention. The case study of Brazil's role in the Dominican Republic in 1965 which follows provides a unique opportunity to examine the impact of traditional forces and contemporary events on Brazilian foreign policy at a critical juncture in that nation's history.

Introdução: É notável o crescimento na produção de conhecimento na área da psicologia do esporte (PE). O conhecimento produzido pelos pesquisadores ocorre através da publicação de seus trabalhos no formato de artigos em periódicos científicos. Não existe na literatura análises considerando os periódicos específicos da área e suas características. Objetivo: Discutir acerca do cenário atual de periódicos específicos relacionados à PE. Métodos: Trata-se de uma pesquisa documental a respeito dos periódicos de PE. Foram extraídos e analisados dados como país, instituição, editora, língua de publicação, as métricas (JCR - ISI Web of Science, SJR, Citescore e SNIP – Scopus, e índice h5 – Google Scholar), periodicidade, período de publicações e número de artigos publicados em 2018. Resultados: Foram observados 14 periódicos na literatura relacionados diretamente a temática da PE. A maioria dos periódicos (5) é dos Estados Unidos, três da Espanha e três do Reino Unido. Brasil, Itália e Holanda apresentaram um periódico cada. A maioria dos periódicos publica na língua inglesa (13 dos 14). O fator de impacto (JCR) dos periódicos variou de 0,64 a 6,90, cinco periódicos não apresentaram essa métrica em 2018. Neste ano, os periódicos publicaram de 11 até 144 artigos. Conclusão: A partir da análise dos periódicos científicos específicos da PE, verificou-se que os de maior qualidade considerando as métricas analisadas, são dos Estados Unidos e da Europa. No Brasil ressalta-se a necessidade de fortalecimento do periódico específico existente na área, que pode ser realizado a partir da unificação das organizações que atuam na prática profissional e na pesquisa científica em PE. ABSTRACT. Sport psychology research and the specific journals scenario. Background: There is a remarkable growth in the production of knowledge in the field of sports psychology (SP). The knowledge produced by researchers occurs through the publication of their work in the format of articles in scientific journals. There are no analyses in the literature considering the specific journals of the area and their characteristics. Objective: To discuss about the current scenario of specific journals related to SP. Methods: This is a documentary research about the SP journals. The following data were extracted and analyzed: country, institution, publisher, publication language, metrics (JCR - ISI Web of Science, SJR, Citescore and SNIP – Scopus, and index h5 – Google Scholar), periodicity, publication period, and number of articles published in 2018. Results: It was observed 14 journals related to SP. Most of them are from United States, three from Spain and three from United Kingdom. Brazil, Italy and Netherlands showed one journal each. Most of the journals publish in English language (13 of 14). The impact factor ranged from 0.64 to 6.90, and five journals do not show this metric in 2018. In this year, the journals published from 11 to 144 articles. Conclusion: From the analysis of the specific scientific journals of the SP, it was found that the journals with highest quality are from the United States and Europe. In Brazil, there is a need to strengthen the existing specific journal in the area, which can be done by unifying the organizations that work in professional practice and scientific research of SP.

Background: Pharmaceutical services performed in the hospital context have specific structure and processes, which should be continuously evaluated because they influence the results obtained. Objective: To identify, describe and compare studies of evaluation of pharmaceutical services performed in the hospital context. Methods: Integrative review of articles found in databases SciELO, LILACS, MEDLINE and IBECS, indexed in the period from 2000 to 2016, using the following descriptors: “Hospital Pharmacy Service” and “Evaluation“. The references were analyzed according to year, language, country of publication and type of study and classified according to their focus on the components of the hospital pharmacy service logic model that dealt with the management, selection, programming, acquisition, storage and distribution of medicines, information, pharmacotherapeutic, pharmacotechnical and teaching and research follow-up. Results: Of the 25 publications, 16 (64%) were in the English language, of which 10 (40%) were in the United States; 17 (70%) studies were published from 2010 to 2016 and 13 (52%) were observational descriptive type. The most discussed component of pharmaceutical services was distribution logistics addressed in 15 publications (60%), followed by the management component addressed by 14 (56%) studies. Conclusions: The publications emphasized the discussion on drug logistics. Only a few presented discussions on the impact of these services on health care, such as patient safety. Such studies can support the decision-making process and the formulation of strategies aimed at increasing the management capacity and the quality of the service provided.
