Abstract
Introdução: O envelhecimento humano interfere diretamente no desempenho do atleta master, portanto, saber em que momento ocorre este declínio de desempenho se torna essencial para a otimização do esporte master. Objetivo: Objetivou-se analisar a taxa de declínio dos tempos de nadadores masters em diferentes categorias etárias (25 a 99 anos). Metodologia: Os dados dos até 8 primeiros colocados dos 50 e 800 metros nado livre de cada categoria participante do Campeonato Brasileiro Master de 2019 foram coletados, totalizando 281 entradas na água. Foi realizada análise descritiva e inferencial. Resultados e discussão: Os 50 metros livre foi a prova com maior número de entradas; observou-se na comparação recordes de categorias vs. recordes nacionais que as maiores diferenças percentuais ocorreram, em geral, a partir dos 60 anos. Este resultado é similar ao da comparação das médias das entradas de cada prova vs. recorde da categoria. Ainda, ao comparar a média das entradas vs. categoria 25-9 anos observou-se no masculino, e no feminino, diferenças significativas com as categorias 65-9 anos até 85-9 anos. Nos 800 livre, maiores diferenças percentuais também foram observadas a partir dos 60 anos para recordes de categorias vs. recordes nacionais. Contudo, ao analisar as médias das entradas de cada prova vs. recordes de cada categoria e ao comparar as médias das entradas vs. categoria 25-9 anos, não se observou diferenças significativas para o feminino, enquanto que para o masculino, esta diferença ocorreu a partir da categoria 60-4 anos. Conclusão: Concluiu-se que a queda de desempenho nas provas da natação master analisadas é influenciada, em parte pelo processo de envelhecimento, sexo e a competição de referência.

Anatomy applied to image diagnosis of the hind limb in the black-striped capuchin (Sapajus libidinosus Spix, 1823). Am J Primatol 2022; 84:e23416. [PMID: 35848101 DOI: 10.1002/ajp.23416] [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: 03/15/2022] [Revised: 05/27/2022] [Accepted: 06/15/2022] [Indexed: 11/09/2022]
Abstract
The knowledge of anatomy and imaging exams emerges as an important tool in the study of evolutionary processes of a species, in the elaboration of diagnosis, and the successful choice of the appropriate clinical and surgical procedures. Therefore, this study aims to describe the osteology of the hind limb of Sapajus libidinosus by means of gross, radiographic, and tomographic images. Four cadavers were used in the macroscopic analysis and five animals for the imaging exams, of which four were eventually euthanized and added to the macroscopic study. For imaging exams, they were kept anesthetized. All bones of the hind limb were documented, their structures were described, and compared with data in the literature from human and nonhuman primates. We have performed Student's t test for independent samples. There was no statistical difference between the sexes regarding the length of the hind limb bones. The coxal bone was largely well described using imaging methods. A small penile bone was present at the tip of the penis and it could be identified by all analysis methods. The femur, as well as the tibia and fibula, were not well portrayed in their proximal and distal epiphyses by radiography (Rx). However, they were well identified on tomography. No third trochanter was observed in the femur and the patella had a triangular shape. All the structures described by gross anatomy of the tarsus and metatarsus could be identified by Rx and tomography. More subtle structures, such as the popliteal notch on the tibia, and the gluteal tuberosity pectineal line and facies aspera on the coxal bone, were not identified by medical imaging. S. libidinosus presented anatomical characteristics that were similar to those of larger New World and Old World monkeys, including man. This suggests it's value as an experimental model for studies in recent primates.

Abstract
Este trabalho tem como foco a construção do declínio hormonal masculino relacionado ao envelhecimento, como parte de um processo mais geral de medicalização da sexualidade e envelhecimento masculinos. A fim de atingir esse objetivo, foram pesquisados 14 websites de laboratórios farmacêuticos que comercializam drogas para a saúde sexual masculina e sete websites de associações médico-científicas voltadas para a saúde sexual masculina. Utilizamos as imagens encontradas em tais sites como material de análise. A partir do que foi analisado, discutimos a existência de uma parceria entre as associações médico-científicas e a indústria farmacêutica, que tende a apresentar o envelhecimento masculino como um problema médico, promovendo a terapia de reposição hormonal (TRH) com testosterona como tratamento. Tal terapia é também apresentada como um meio para recuperar a felicidade, a produtividade, a ‘qualidade de vida’ e o bem-estar.

Abstract
O objetivo do presente trabalho foi realizar uma revisão bibliográfica dos estudos sobre envelhecimento no âmbito das ciências da saúde, a fim de apresentar um panorama do que tem sido pesquisado sobre o assunto na América Latina e no Brasil no período de 1982 a 2010. Utilizou-se a bases de dados LILACS disponível on line na Biblioteca Virtual em Saúde (BVS). Constatou-se um aumento expressivo do número de publicações a partir de 2006, principalmente nas categorias: estado de saúde (51%, n=318), avaliação cognitiva (12,72%, n=66), estudos sociodemográficos (6,16% n=32), medicamentos (3,27% n=17) e avaliação funcional (3,08% n=16). Na categoria estado de saúde, houve maior número de publicações relativas a atividade física (17,9% n=57), doenças cardiovasculares (11,95% n=38), dieta (7,6% n=24), saúde bucal (6,6% n=21), menopausa/andropausa (6,3% n=20), quedas (5,97% n=19), atividade sexual (5,03% n=16) e depressão (4,1% n=13). Concluiu-se que é importante estudar estes temas relacionados à senescência, para contribuir com a qualidade de vida nesta faixa etária.

Abstract
OBJECTIVE To compare the modalities of treatment for male hypogonadism available in Brazil. METHODS Thirty-two men with late-onset hypogonadism ('andropause') were followed-up in the Hospital de Guarnição de Florianópolis, in Florianópolis, south Brazil. Clinical diagnosis was established according to AMS questionnaire (positive if equal to or higher than 27 points), and laboratory diagnosis was made through low values of total testosterone (under 300 ng/dL) and/or free calculated testosterone (under 6.5 ng/dL). Patients were randomized to three non-enteral treatment groups (Deposteron--11 patients; Durateston--11 patients; and Nebido--10 patients). RESULTS Clinically, Nebido seemed to be superior when compared to Deposteron (mean value of improvement percentage; p = 0.03) and when compared to Durateston (post-treatment average AMS score; p = 0.03). According to laboratory analysis, Nebido showed higher testosterone levels than Deposteron and Durateston (p < 0.001). CONCLUSIONS All non-enteral testosterone formulas available in the Brazilian market are efficient in raising testosterone levels and in clinical improvement of hypogonadal patients. Nebido showed both a better clinical and laboratory effectiveness.

Abstract
The use of testosterone in older men, known as male hormonal replacement therapy or androgen replacement therapy, has become of increasing interest to both the medical and lay communities over the past decade. Even though the knowledge of the potential benefits and risks of male Androgen Replacement Therapy has increased dramatically, there is still much that needs to be determined. Although there are a number of potential benefits of male Androgen Replacement Therapy and data concerning clinical effects of such replacement have accumulated, as yet there have not been any large multicenter randomized controlled trials of this therapy. It is the purpose of this article to review what is currently known about the possible risks and benefits of male Androgen Replacement Therapy by discussing the clinical trials to date.
