ABSTRACT Objectives: Currently, not much is known about the interactions between voice and growth hormone (GH). We have described large kindred with isolated GH deficiency (IGHD) due to a GHRH receptor mutation, resulting in severe short stature and high-pitched voice. These IGHD individuals have little interest in GH treatment, as they consider themselves “short long-lived people”, rather than patients. Interestingly, they report normal general quality of life, but they rate their Voice-Related Quality of Life (V-RQOL) as low. Here, we assessed the social and auditory-perceptual impacts of artistic-intervention voice therapy with semioccluded vocal tract exercises (SOVTE) and choral singing, on their voices. Material and methods: Seventeen GH-naïve adult IGHD individuals were enrolled in a single-arm interventional pre-post study with 13 weekly sessions of choir singing over 90 days. Outcome measures were V-RQOL scores, self-assessment of voice, and auditory-perceptual analysis (GRBAS scale, G: grade of the severity of dysphonia; R: roughness; B: breathiness; A: asthenia; and S: strain). Results: Marked improvements in total (p = 0.0001), physical (p = 0.0002), and socioemotional (p = 0.0001) V-RQOL scores and in self-assessment of voice (p = 0.004) were found. The general grades of vocal deviation (p = 0.0001), roughness (p = 0.0001), breathiness (p = 0.0001) and strain (p = 0.0001) exhibited accentuated reductions. Conclusions: Voice therapy with semioccluded vocal tract exercises and choral training improved social impact and perceptual voice assessments in IGHD subjects and markedly improved their voice-related quality of life. This is particularly important in a setting where GH replacement therapy is not widely accepted.

Resumo: Objetivo As amebas testáceas são protistas de vida livre reconhecidas como bioindicadores, capazes de revelar alterações ambientais apresentando variação de riqueza, diversidade e abundância de espécies. Para avaliar a produção científica relativa ao uso de amebas testáceas como bioindicadores, foi realizada uma análise cienciométrica no período de 1960 a 2020. Métodos A seleção de artigos científicos foi feita nas plataformas Google Acadêmico, Scielo, Science Direct e Online Library. Todos os artigos selecionados foram categorizados por cronologia, periódico de publicação, país, afiliação dos autores, se o estudo era empírico ou experimental, se incluía apenas amebas testáceas e aspectos do meio ambiente. Resultados Um total de 215 artigos de noventa e dois periódicos revelou um aumento notável no número de publicações nas últimas décadas. Os dois periódicos que mais publicaram dados sobre o tema foram Microbial Ecology e Ecological Indicators. Embora o maior número de trabalhos tenha sido publicado no continente europeu, os países que mais contribuíram para o tema foram o Canadá na região temperada e o Brasil nos trópicos. Edward A.D. Mitchell publicou o maior número de estudos e em termos de instituição, a Universidade Franche-Comté. A maioria dos trabalhos que associaram amebas testáceas como bioindicadores foram empíricos, realizados tecamebas habitantes de musgos e, como tal, dissociadas de outros grupos. Conclusões Apesar do aumento verificado nas publicações com testáceas como bioindicadores, nossos resultados indicam uma concentração de estudos em regiões limitadas do globo. Sob outro aspecto, um grande número de estudos avaliou a comunidade de testáceas como um todo, mostrando uma escassez de conhecimento aprofundado sobre espécies e grupos funcionais. Com isso, nosso levantamento aponta para uma grande variedade de ecossistemas aquáticos desprovidos de estudos sobre o assunto, indicando a necessidade de fomentar a pesquisa sobre o papel das amebas testáceas como bioindicadoras, em especial nas regiões tropicais.

Abstract: Aim The free-living protists testate amoebae are recognized as being bioindicators, able to reveal environmental alteration via remodifying richness, diversity and abundance of species. To assess the scientific production on the use of testate amoebae as bioindicators, a scientometric analysis was undertaken from 1960 to 2020. Methods The sourcing of scientific articles derived from Google Academic, Scielo, Science Direct and Online Library research platforms. All selected papers were factored according to chronology, journal of publication, country, authors’ affiliation, whether the study was empirical or experimentation, if it included solely testate amoebae or other groups of organisms, and aspects of the environment. Results A total of 215 papers from ninety-two journals revealed a notable increase in publication numbers over the last decades. The two journals that most published data on this theme were Microbial Ecology and Ecological Indicators. Whilst the largest number of papers was published in the European Continent, the countries that most contributed to the subject were Canada in the temperate region and Brazil in the tropics. Edward A.D. Mitchell published the largest number of studies and regarding institutions the Franche-Comté University. The majority of papers that associated testaceans as bioindicators were empirical, conducted with Thecamoebian inhabiting moss and as such, dissociated from other groups. Conclusions Despite a suggested uptick in research of testaceans as bioindicators, our results indicate a concentration of studies to limited regions of the globe. In another aspect, a great number of studies assess testaceans’ community as-a-whole, showing a shortage of in-depth knowledge into species and functional groups. Therefore, our survey points to a wide variety of aquatic ecosystems devoid of study matter, indicating the need to foster the research on testate amoeba's role as bioindicators especially in the tropical regions.

INTRODUÇÃO: Sendo o futebol um esporte de grande popularidade em todo o mundo e principalmente no Brasil, vários estudos procuram formar um perfil das lesões e dos jogadores mais propensos a elas; porém, este tipo de estudo é raro na região norte do País. OBJETIVO: Analisar a incidência de lesões musculoesqueléticas nos jogadores de futebol profissional do Clube do Remo, Belém, PA. MÉTODOS: Foram analisados 27 jogadores de futebol profissional do Clube do Remo, durante o Campeonato Paraense de futebol de 2010. Os dados foram coletados através da verificação dos prontuários e aplicação de um questionário semicodificado para os atletas; posteriormente foi realizada a análise estatística. RESULTADOS: Ao analisar a amostra, verificou-se que a maioria das lesões foi de contraturas e contusões, os locais corpóreos mais acometidos foram a coxa e o joelho e a posição em campo mais lesionada foi a de meio de campo. CONCLUSÃO: Ocorreram várias lesões musculares; por isso, é necessário um acompanhamento da equipe multiprofissional, já que este tipo de lesão não ocorre devido a trauma e sim pelos movimentos que os jogadores são impostos durante os jogos e treinos.

INTRODUCTION: Due to soccer worldwide popularity, especially in Brazil, several studies try to outline a profile of injuries and players more prone to it; however, this kind of study is rare in the northern region of our country. OBJETIVE: To analyze the incidence of musculoskeletal injuries on professional soccer players of Remo Club. METHODS: We analyzed 27 professional soccer players of Remo Club were analyzed during the Soccer Championship from Pará State, 2010. Data were collected through verification of records and application of a semi-coded questionnaire to the athletes; subsequently, statistical analysis was conducted. RESULTS: By analyzing the sample, it was found that most of the injuries were contractures and contusions (bruises), the body parts most affected were the thigh and the knee and the athletes who suffered the most damage were midfielders. CONCLUSION: Several muscular injuries were observed; therefore, a follow-up of the multidisciplinary staff is needed, since this kind of injuries does not occur due to trauma, but rather due to the movements imposed to the players during games and practice. Thus, adequate physical preparation can reduce the incidence of this type of injuries.
