ABSTRACT OBJECTIVE The transgender population in Brazil faces marginalization and difficulties in accessing education and health, leading many individuals to self-medicate. This study aimed to evaluate the impact of the implementation of Specialized Centers in the Transsexualizing Process (SCTP) on the use of cross-sex hormone therapy (CSHT) without medical prescription, as well as the level of education and mental health profile of these individuals. METHODS This is a cross-sectional study with data from physical and electronic medical records between September 2017 and February 2023 regarding the use of CSHT before and after the implementation of two SCTP in the state of Bahia, Brazil, in addition to data on education level, previous diagnosis of anxiety and depression of patients. RESULTS A total of 219 participants, 127 transgender men (TM) and 92 transgender women and travestis (TrTW), were assessed. A significant reduction in the prevalence of self-medication was observed in both TrTW (92.98% before and 51.43% after, p<0.001), and TM (47.17% before and 25.67% after, p = 0.010) with the implementation of SCTP. Transgender individuals who used CSHT before accessing the service were found to have a lower prevalence of depression. Self-medication was not significantly associated with education or anxiety in our sample. CONCLUSION The results indicate the need for the expansion of SCTP, as they were associated with lower rates of self-medication in the transgender population. selfmedicate. selfmedicate self medicate. medicate self-medicate (SCTP crosssex cross sex (CSHT prescription crosssectional sectional 201 202 Bahia patients 21 participants 12 (TM 9 TrTW, , (TrTW) assessed selfmedication medication 92.98% 9298 98 (92.98 5143 51 43 51.43 p<0.001, p0001 p<0.001 0 001 p<0.001) 47.17% 4717 47 17 (47.17 2567 25 67 25.67 0.010 0010 010 Selfmedication Self sample 20 2 1 (TrTW 92.98 929 (92.9 514 5 4 51.4 p000 p<0.00 00 47.17 471 (47.1 256 6 25.6 0.01 01 92.9 (92. 51. p00 p<0.0 47.1 (47. 25. 0.0 92.

The aim of this study was to assess the effect of eugenol on the in vitro production of ovine embryos. Oocytes were aspirated and taken for in vitro maturation (IVM), where they were divided into 4 groups: the CON (control), in which the oocytes were immersed in medium without an antioxidant; in the EU10, EU20, EU40 groups, the same medium as in the COM group was used, supplemented with 10, 20, and 40 µM of eugenol, respectively. The degree of expansion of cumulus cells was evaluated. Subsequently, the oocytes underwent in vitro fertilization and in vitro culture, and at the end of this process, the rate of cleaved structures was assessed. Regarding the expansion rate of cumulus cells, the CON group exhibited higher rates compared to the groups supplemented with eugenol. Evaluating oocytes with fully expanded cumulus cells, only the EU40 group showed a lower rate when compared to the rest of the treatment groups. Whereas observing oocytes with partially expanded cumulus cells, the EU40 group showed higher expansion percentages compared to the other treatments. Concerning the presence of the first polar body in the oocytes, it was observed that there was no statistical difference between the treatment groups. Lastly, concerning the cleaved structures, the CON and EU10 groups showed the highest rates compared to the EU20 and EU40 groups. Thus, it was possible to conclude that the use of 10 µM of eugenol in the IVM of ovine oocytes proved to be the optimal concentration of this substance.

El objetivo del presente estudio fue evaluar el efecto del eugenol en la producción in vitro de embriones ovinos. Los ovocitos fueron aspirados y llevados para la maduración in vitro (MIV), donde se dividieron en 4 grupos: el CON (control), en el cual los ovocitos fueron sumergidos en medio sin antioxidantes; en los grupos EU10, EU20, EU40 se utilizó el mismo medio que en el grupo CON, pero con la adición de 10, 20 y 40 µM de eugenol, respectivamente. Se evaluó el grado de expansión de las células del cúmulo. Después de esto, los ovocitos fueron sometidos a la fecundación in vitro y al cultivo in vitro, y al final de este proceso se evaluó la tasa de estructuras clivadas. En cuanto a la tasa de expansión de las células del cúmulo, el grupo CON mostró tasas más altas en comparación con los grupos suplementados con eugenol. Al evaluar los ovocitos con células del cúmulo totalmente expandidas, solo el grupo EU40 mostró una tasa más baja en comparación con el resto de los grupos de tratamiento. Mientras que al observar los ovocitos con células del cúmulo parcialmente expandidas, el grupo EU40 mostró porcentajes de expansión más altos en comparación con los otros tratamientos. Respecto a la presencia del primer corpúsculo polar en los ovocitos, se observó que no hubo diferencia estadística entre los grupos de tratamiento. Por último, en relación con las estructuras clivadas, los grupos CON y EU10 mostraron las tasas más altas en comparación con los grupos EU20 y EU40. Por lo tanto, se pudo concluir que el uso de 10 µM de eugenol en la MIV de ovocitos ovinos resultó ser la concentración óptima de esta sustância.

Os oócitos, foram aspirados e levados para a maturação in vitro (MIV), onde foram divididos em 4 grupos: o CON (controle), no qual os oócitos foram imersos em meio, sem antioxidante, já nos grupos EU10, EU20, EU40 foi utilizado o mesmo meio do grupo CON, acrescido de 10, 20 e 40 µM de eugenol, respectivamente. Foi avaliado o grau de expansão das células do cumulus. Após isso, os oócitos seguiram para a fecundação in vitro e cultivo in vitro, sendo, ao final desse processo, avaliada a taxa de estruturas clivadas. Em relação à taxa de expansão das células do cumulus, o grupo CON apresentou maiores taxas, quando comparado aos grupos adicionados de eugenol. Avaliando os oócitos com células do cumulus totalmente expandidas, somente o grupo EU40, apresentou-se menor, quando comparado ao restante dos grupos de tratamento. Já observando os oócitos com células do cumulus parcialmente expandidas, o grupo EU40, apresentou maiores percentuais de expansão, quando comparado aos demais tratamentos. Sobre a presença do primeiro corpúsculo polar nos oócitos, observou-se que não houve diferença estatística entre os grupos de tratamentos. E, por último, em relação às estruturas clivadas, os grupos CON e EU10 apresentaram as maiores taxas, quando comparado aos grupos EU20 e EU40. Dessa maneira, foi possível concluir que a utilização de 10 µM de eugenol na MIV de oócitos ovinos apresentou ser a melhor concentração dessa substância.

The aim of this study was to evaluate the effect of quercetin on the in vitro maturation (IVM) of oocytes and the subsequent in vitro fertilization (IVF) of ovine embryos. For this purpose, oocytes were collected and divided into the following treatment groups: control group, containing CON medium (control); and groups Q2, Q4, and Q8, with control medium supplemented with 2, 4, and 8 µM of quercetin, respectively. After IVM, the degree of cumulus cells expansion, presence of the first polar body (PB), and the other part of the oocytes proceeded to in vitro fertilization (IVF), where oocytes were incubated with spermatozoa for a period of 20 hours. Subsequently, the presumptive zygotes underwent in vitro culture (IVC) for 48 hours, and at the end of the process, the rate of cleaved structures was evaluated. The results were expressed in percentage and compared using the Chi-square test, with a significant difference considered when P&lt;0.05. Evaluating the expansion of cumulus cells, the CON and Q2 groups showed the best expansion rates compared to the Q4 and Q8 groups. Regarding the presence of the 1st PB, it was observed that only the Q8 group exhibited lower rates compared to the control group. When evaluating the rate of cleaved structures, it was observed that the Q2 group showed a higher number compared to the Q8 group. Quercetin does not influence the maturation of ovine oocytes.

El objetivo del presente estudio fue evaluar el efecto de la quercetina en la maduración in vitro (MIV) de ovocitos y la posterior fertilización in vitro (FIV) de embriones ovinos. Para ello, se recolectaron y seleccionaron ovocitos divididos en los siguientes grupos de tratamiento: grupo control, que contenía medio CON (control); y los grupos Q2, Q4 y Q8, con medio control al que se le añadieron 2, 4 y 8 µM de quercetina, respectivamente. Tras la MIV se evaluó el grado de expansión de las células del cúmulo, la presencia del primer corpúsculo polar (CP) y la otra parte de los ovocitos se utilizó para la fecundación in vitro (FIV), donde los ovocitos fueron incubados con espermatozoides durante un período de 20 horas. Posteriormente, los presuntos cigotos pasaron a cultivo in vitro (CIV) durante 48 horas y, al final del proceso, se evaluó la tasa de estructuras clivadas. Los resultados se expresaron en porcentaje y se compararon utilizando la prueba de Chi-cuadrado, considerando una diferencia significativa cuando P&lt;0,05. Al evaluar la expansión de las células del cúmulo, los grupos CON y Q2 mostraron las mejores tasas de expansión en comparación con los grupos Q4 y Q8. En cuanto a la presencia del 1er CP, se observó que solo el grupo Q8 mostró tasas más bajas en comparación con el grupo control. Al evaluar la tasa de estructuras clivadas, se observó que el grupo Q2 mostró un número mayor en comparación con el grupo Q8. La quercetina no influye en la maduración de ovocitos ovinos.

Para isso, foram colhidos e selecionados oócitos divididos nos seguintes grupos de tratamento: grupo controle, contendo meio CON (controle); e grupos Q2, Q4 e Q8, com meio controle, acrescido de 2, 4 e 8 µM de quercetina, respectivamente. Após a MIV foi avaliado o grau de expansão das células do cumulus, presença do primeiro corpúsculo polar (CP) e a outra parte dos oócitos seguiu para a fecundação in vitro (FIV), onde os oócitos foram incubados com os espermatozoides, por um período de 20 h. Em seguida, os presumíveis zigotos seguiram para o cultivo in vitro (CIV), por um período de 48 h e, ao final do processo, foi avaliada a taxa de estruturas clivadas. Os resultados foram expressos em porcentagem e comparados, usando o Teste do Qui-quadrado e foi considerada diferença significativa quando P&lt;0,05. Avaliando a expansão das células do cumulus, os grupos CON e Q2 apresentaram as melhores taxas de expansão, quando comparadas aos grupos Q4 e Q8. Quanto à presença do 1º CP, foi possível observar que somente o grupo Q8 apresentou taxas menores, quando comparado ao grupo controle. Já avaliando a taxa de estruturas clivadas, foi possível observar que o grupo Q2 apresentou maior número quando comparado ao grupo Q8. A quercetina não influencia na maturação de oócitos ovinos.

ABSTRACT: The objective of this work is to analyse As doenças do Brasil (2021), by the Portuguese writer Valter Hugo Mãe. The novel develops around the Abaeté, a fictional indigenous ethnic group. In the middle of the colonial period, the Abaeté do not live in peace, as they are harassed by the Portuguese, who want to usurp their lands and subject their bodies. Our analysis will be based on ecocriticism, a current of Literary Ccriticism that studies artistic expressions that deal with the environment throughout the planet, without distinction of borders. However, the greatest contribution to our work comes from two indigenous thinkers: Davi Kopenawa (2010) and Ailton Krenak (2019). We also intend to consider some aspects related to ethics and aesthetics from the ideas of Murcho (2015) and Hermann (2005).

RESUMO: O objetivo deste trabalho é analisar As doenças do Brasil (2021), do escritor português Valter Hugo Mãe. O romance se desenvolve em torno dos Abaeté, etnia indígena ficcional. Em pleno período colonial, os Abaeté não vivem em paz, pois estão acossados pelos portugueses, que desejam usurpar suas terras e submeter seus corpos. Nossa análise se baseará na ecocrítica, corrente da Crítica Literária que estuda expressões artísticas que se ocupam do meio ambiente em todo o planeta, sem distinção de fronteiras. No entanto, a maior contribuição ao nosso trabalho advém de dois pensadores indígenas: Davi Kopenawa (2010) e Ailton Krenak (2019).

Abstract The objective of this work was to establish possible lexical ambiguities related to the words chance, random and uncertainty by 61 students of the fifth year of Elementary School (9 to 11 years old) of a public school in Barueri, São Paulo, Brazil, seeking find out what probabilistic meanings do they indicate based on everyday knowledge and/or what they learned at school. This was exploratory research, with a qualitative and quantitative approach, in which multivariate textual analyzes were carried out, such as Similarity Analyzes and Descending Hierarchical Classification - CHD, using the IRaMuTeQ software (R Interface for Multidimensional Text and Questionnaire Analysis). The results indicate that children have formalized, even if intuitively, since the early years of basic education, probabilistic notions such as, for example, determining the meaning of the words chance, random and uncertainty, and there should be concern in working on these concepts. We conclude that, lexical ambiguities are presented in relation to the terms under study, starting from the intuitive meaning that is constituted as a basic element that the students presented for then, to build a connection with the probabilistic language, allowing them to start using a precise language and specialized.

Abstract Changes in climate, which can be understood as fluctuations in climate patterns as a reflection of natural or anthropic interventions, can generate changes in the environment and consequently affect the diversity of organisms. Fungi are extremely important in organic matter cycling in different environments, mainly forest areas, decomposing dead wood. To better understand the effects of climate change on two wood-degrading Agaricomycetes, their potential neotropical distribution was modeled using known occurrence data, available in the GBIF database and in specific literature, and associated with predictor variables extracted from Worldclim. A modeling package in R environment was used to analyze the present and future suitability for the optimistic and pessimistic scenarios. The results indicate the climate as an important factor in the distribution of Auricularia brasiliana and Megasporoporia neosetulosa. The suitability factors for the metrics used indicate that the models can be used to analyze climatic areas and that temperature and precipitation strongly influence the permanence of species in these locations. The results also indicate areas that can be affected by climatic effects, consequently causing a decrease in the occurrence and permanence of these fungi in the Neotropics. Our models can be useful as future guidelines in conservation studies for fungi. interventions organisms environments wood wooddegrading degrading Agaricomycetes data literature Worldclim scenarios neosetulosa locations Neotropics

ABSTRACT The production of green maize is considerable important for various regions of Brazil. It is vital that breeding programs of public institutions seek to meet the needs of this market sector, which has a relevant social role, mainly on small properties. The aim of this study was to estimate the inbreeding depression and the genetic components (m + a and d) of characters associated with green maize production and quality in three populations of different genetic basis: the variety UFG-Samambaia (P1), and two populations formed by crossing the commercial hybrids (P2 e P3). The S1 progenies of each population, the three S0 populations, and two checks were evaluated in a 14 × 14 triple lattice design. Agronomic and ear quality traits were evaluated. Genetic variability and greater inbreeding depression were observed for most of the traits among the P1 progenies. In P2 and P3, greater inbreeding depression was observed for male flowering, ear weight without straw, ear diameter, ear weight, female flowering, breakage and lodging, and grain color. The traits of ear quality, important for green maize production, had greater inbreeding depression than the agronomic traits, indicating that inbreeding depression and exploitation of heterosis should be considered in the selection process for these traits.

Abstract This article aims to investigate the association between maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) with the incidence of frailty syndrome (FS), in addition to testing the predictive ability of MIP and MEP to discriminate FS in elderly adults, according to sex. It is a longitudinal study with a five-year follow-up period (2014-2019), carried out with 104 elderly adults registered in the Family Health Strategy of a municipality in Bahia. The incidence of frailty syndrome was diagnosed according to criteria proposed by Fried et al., using data from 2019, after a five-year follow-up. The MIP and MEP were evaluated according to the recommendations of the Brazilian Society of Pulmonology and Phthisiology data in 2014 (baseline data). The total incidence of frailty syndrome was 16.3% (95%CI: 9.2-23.6), with 13.6% (95%CI: 4.56-22.55) in women and 20% (95%CI: 7.85-32.15) in men. The mean values of MIP and MEP were, respectively, 60,8±21,2 cmH2O and 76,7±23,1 cmH2O in women, and 79,5±27,0 cmH2O and 114,7±29,8 cmH2O in men. The frailty syndrome was associated with MEP in elderly adult men (adjusted RR: 0.96; 95%CI: 0.95-0.98; P-value: 0.002), indicating that the increase of 1cmH2O in MEP reduces by 4% the risk of developing the syndrome.

Resumo O objetivo deste artigo é investigar a associação entre a Pressão Inspiratória Máxima (PImáx) e Pressão Expiratória Máxima (PEmáx) com a incidência da síndrome de fragilidade (SF), além de testar a capacidade preditiva da PImáx e PEmáx em discriminar a SF em idosos, de acordo com o sexo. Estudo longitudinal com cinco anos de seguimento (2014-2019), realizado com 104 idosos cadastrados na Estratégia Saúde da Família de um município da Bahia. A incidência da síndrome de fragilidade foi diagnosticada de acordo os critérios propostos por Fried et al., utilizando dados de 2019, após cinco anos de seguimento. A PImáx e PEmáx foram avaliadas conforme recomendações da Sociedade Brasileira de Pneumologia e Tisiologia em 2014 (linha de base). A incidência total da SF foi de 16,3% (IC95%: 9,2-23,6), sendo 13,6% (IC95%: 4,56-22,55) no sexo feminino e 20,0% (IC95%: 7,85-32,15) no sexo masculino. Os valores médios da PImáx e PEmáx foram, respectivamente, 60,8±21,2 cmH2O e 76,7±23,1 cmH2O no sexo feminino, e 79,5±27,0 cmH2Oe 114,7±29,8 cmH2O no sexo masculino. A SF esteve associada à PEmáx em idosos do sexo masculino (RR ajustado: 0,96; IC95%: 0,95-0,98; p-valor: 0,002), indicando que o aumento de 1 cmH2O da PEmáx reduz em 4% o risco de desenvolver a síndrome de fragilidade.

SUMMARY: This study aimed to evaluate the effects of six weeks of HIIT on tissue and oxidative damage markers in rats supplemented with Coutoubea spicata fraction. Thirty-two male Wistar rats were divided into 4 groups: Baseline (GB); supplemented with 100 mg/kg of Coutoubea spicata fraction (GSCS); exercised for 6 weeks with the HIIT protocol (GH); supplemented with 100 mg/kg of Coutoubea spicata fraction + HIIT for 6 weeks (GHCS). Exercised animals performed the HIIT protocol (2 x 2). Tissue damage CK, LDH, ALT and AST markers in plasma were analyzed, as well as oxidative stress MDA and SH biomarkers in plasma and in cardiac, hepatic and muscle tissues. The results showed that CK, LDH, AST and ALT enzymes showed increase in GH when compared to GB (p<0.0001). However, CK, AST and ALT markers reduced their concentrations in GHCS when compared to GH (p<0.0001), indicating that Coutoubea spicata supplementation attenuated the damage in muscle and liver tissues induced by HIIT. Plasma, liver and muscle MDA showed increase in GH after HIIT sessions; however, when compared to GHCS, it showed reduced levels (p<0.0001). SH was elevated in the GH group when compared to GB in plasma and liver tissues (p<0.0001); in contrast, reduction in GHCS when compared to GH was observed in plasma, liver and cardiac tissues, demonstrating the redox effect of HIIT on some tissues. Thus, our findings showed that Coutoubea spicata has antioxidant activity, reducing oxidative damage markers and consequently tissue damage in healthy Wistar rats after HIIT protocol, but it also demonstrated redox balance after analyzing oxidative stress markers.

RESUMEN: Este estudio tuvo como objetivo evaluar los efectos de HIIT en los marcadores de daño tisular y oxidativo en ratas suplementadas con Coutoubea spicata durante seis semanas. Treinta y dos ratas Wistar macho se dividieron en 4 grupos: línea de base (GB); suplementados con 100 mg/kg de fracción de Coutoubea spicata (GSCS); ejercitados durante 6 semanas con el protocolo HIIT (GH); suplementado con 100 mg/kg de fracción de Coutoubea spicata + HIIT durante 6 semanas (GHCS). Los animales ejercitados realizaron el protocolo HIIT (2x2). Se analizaron los marcadores de daño tisular CK, LDH, ALT y AST en plasma, así como los biomarcadores de estrés oxidativo MDA y SH en plasma y en tejidos cardiaco, hepático y muscular. Los resultados indicaron que las enzimas CK, LDH, AST y ALT mostraron aumento en GH en comparación con GB (p<0,0001). Sin embargo, los marcadores CK, AST y ALT redujeron sus concentraciones en GHCS en comparación con GH (p<0,0001), lo que indica que la suplementación con Coutoubea spicata atenuó el daño en los tejidos musculares y hepáticos inducido por HIIT. La MDA de plasma, hígado y músculo mostró un aumento en la GH después de las sesiones de HIIT; sin embargo, en comparación con GHCS, mostró niveles reducidos (p<0,0001). Se observó SH elevado en el grupo de GH en comparación con GB en plasma y tejidos hepáticos (p<0,0001); en contraste, se observó una reducción en GHCS en comparación con GH en plasma, hígado y tejidos cardíacos, lo que demuestra el efecto redox de HIIT en algunos tejidos. Por lo tanto, nuestros hallazgos mostraron que Coutoubea spicata tiene actividad antioxidante, con reducción de los marcadores de daño oxidativo y, en consecuencia, el daño tisular en ratas Wistar sanas después del protocolo HIIT, pero además demostró el equilibrio redox después de analizar los marcadores de estrés oxidativo.

Abstract Aim: This study aimed to identify the prevalence and factors associated with dynapenia in older women, considering different cutoff points as diagnostic criteria. Methods: This epidemiological study was conducted with 205 older women (72.7 ± 7.1 years). Dynapenia was diagnosed using the handgrip strength test (HGS) using two cutoff points (< 16 or < 20 kgf). Socio-demographic, behavioral, and health status information was obtained from a specific form; nutritional status was assessed by body mass index, and the International Physical Activity Questionnaire identified the level of physical activity. Results: The prevalence of dynapenia was 14.1% (HGS < 16 kgf) and 46.3% (HGS < 20 kgf) (p < 0.001). It was also observed that older women with family income ≤ 1 minimum wage and those with low weight presented, respectively, 2.22 (95%CI: 1.12-4.39) and 4.72 (95%CI: 1.64-13.58) times higher probability of dynapenia identified by HGS < 16 kgf. Moreover, for the cutoff point < 20 kgf, the probability of dynapenia was higher in women aged ≥ 80 years (PR:1.91; 95%CI: 1.23-2.95), in insufficiently active women (PR: 1.34; 95%CI: 1.01-2.57), among those with low weight (PR: 1.61; 95%CI: 1.01-2.57), and in those who reported falls (PR:1.42; 95%CI: 1.04-1.96). Conclusion: Therefore, it is concluded that there is a difference between the prevalence and factors associated with dynapenia when different cutoff points are adopted.

RESUMO Objetivos: analisar os conhecimentos, as atitudes e práticas relacionadas às infecções sexualmente transmissíveis de homens em situação prisional. Métodos: estudo qualitativo, baseado na metodologia Conhecimento, Atitude e Prática, realizado com 30 homens em situação prisional. Aplicou-se entrevista individual submetida à Análise do Discurso. Resultados: o conhecimento incipiente dos homens esteve associado ao: adoecimento próprio e do outro, diagnóstico e percepção do comportamento de risco, perpassado pela desconfiança ou não entendimento do teste rápido para detecção. As atitudes envolveram culpabilização das parcerias; não adesão aos insumos de prevenção; resistência na procura por serviços de saúde. As práticas vinculam-se ao cuidado à saúde após a identificação da doença, uso de preservativo peniano e cuidado com as parcerias. Conclusões: o reduzido conhecimento sobre Infecções Sexualmente Transmissíveis torna as atitudes estereotipadas, estigmatizadas, comprometidas pelo nível de instrução. As práticas são fragilizadas pelo nível de assistência à saúde e pelos limites da privação de liberdade.

ABSTRACT Objectives: to analyze the knowledge, attitudes, and practices related to sexually transmitted infections of men in prison. Methods: qualitative study, based on the methodology Knowledge, Attitude and Practice, conducted with 30 men in prison. The study applied individual interviews submitted to the analyze of the discourse. Results: the incipient knowledge of men was associated with: self-illness and the others’, diagnosis, and perception of risk behavior, pervaded by distrust or lack of understanding of the rapid test for detection. The attitudes involved culpability of partnerships, non-adherence to prevention inputs, and resistance to look for health services. The practices are linked to health care after the identification of the disease, use of penile condoms, and attention to the partnership. Conclusions: the reduced knowledge about Sexually Transmitted Infections makes attitudes stereotyped, stigmatized, compromised by the level of education. The level of health care and the limits of deprivation of liberty weaken the practices.

RESUMEN Objetivos: analizar conocimientos, actitudes y prácticas relacionadas a enfermedades de transmisión sexual de hombres en situación de prisión. Métodos: estudio cualitativo, basado en la metodología Conocimiento, Actitud y Práctica, realizado con 30 hombres de la prisión. Aplicada entrevista individual sometida a Análisis del Discurso. Resultados: el conocimiento incipiente de los hombres estuvo relacionado a: propia enfermedad y del otro, diagnóstico y percepción de conducta de riesgo, pasado por desconfianza o no entendimiento del test rápido para detección. Las actitudes envolvieron culpabilización de parejas; no adhesión a insumos de prevención; resistencia a búsqueda por servicios de salud. Las prácticas se vinculan al cuidado de salud tras identificación de la enfermedad, uso de preservativo peniano y cuidado con las parejas. Conclusiones: el reducido conocimiento sobre Infecciones de Transmisión Sexual vuelve las actitudes estereotipadas, estigmatizadas, comprometidas por nivel de instrucción. Las prácticas son debilitadas por nivel de asistencia de salud y límites de privación de libertad.

RESUMO Objetivo: Comparar as pressões respiratórias máximas e parâmetros espirométricos entre idosos classificados como sem sarcopenia, sarcopenia provável e sarcopenia confirmada e testar a capacidade dessas variáveis de discriminar sarcopenia em idosos residentes em comunidade. Métodos: Estudo transversal envolvendo 221 idosos (≥ 60 anos) de ambos os sexos. Sarcopenia foi diagnosticada de acordo com o novo consenso do Grupo de Trabalho Europeu sobre Sarcopenia em Pessoas Idosas. As pressões respiratórias máximas e parâmetros espirométricos foram avaliados. Resultados: As prevalências de sarcopenia provável e sarcopenia confirmada foram de 20,4% e 4,1%, respectivamente. Independentemente do sexo, aqueles com sarcopenia confirmada apresentaram PEmáx significativamente menor do que aqueles sem sarcopenia e provável sarcopenia, enquanto apenas os homens com sarcopenia confirmada apresentaram PImáx significativamente menor do que os outros indivíduos. Houve uma associação inversa de PImáx e PEmáx com sarcopenia, indicando que a diminuição de 1 cmH2O nesses parâmetros aumenta a chance de sarcopenia em 8% e 7%, respectivamente. Os parâmetros espirométricos não foram associados à sarcopenia. Os pontos de corte para PImáx e PEmáx, respectivamente, foram ≤ 46 cmH2O e ≤ 50 cmH2O para mulheres idosas, enquanto foram ≤ 63 cmH2O e ≤ 92 cmH2O para homens idosos, e ambas foram identificadas como preditores de sarcopenia (ASC ROC > 0,70). Conclusões: A sarcopenia associou-se a pressões respiratórias máximas mais baixas, mas não a parâmetros espirométricos. As pressões respiratórias máximas podem ser usadas como marcadores de sarcopenia em idosos residentes em comunidade, independentemente do sexo.

ABSTRACT Objective: To compare maximum respiratory pressures and spirometric parameters among elderly individuals classified as having no sarcopenia, probable sarcopenia, and confirmed sarcopenia, and to test the ability of these variables to discriminate sarcopenia in a community-dwelling elderly population. Methods: This was a cross-sectional study involving 221 elderly (≥ 60 years of age) individuals of both sexes. Sarcopenia was diagnosed in accordance with the new consensus of the European Working Group on Sarcopenia in Older People. Maximum respiratory pressures and spirometry parameters were assessed. Results: The prevalences of probable sarcopenia and confirmed sarcopenia were 20.4% and 4.1%, respectively. Regardless of the sex, those with confirmed sarcopenia had significantly lower MEP than those with no sarcopenia and probable sarcopenia, whereas only males with confirmed sarcopenia presented with significantly lower MIP than did the other individuals. There was an inverse association of MIP and MEP with sarcopenia, indicating that the decrease by 1 cmH2O in these parameters increases the chance of sarcopenia by 8% and 7%, respectively. Spirometric parameters were not associated with sarcopenia. Cutoff points for MIP and MEP, respectively, were ≤ 46 cmH2O and ≤ 50 cmH2O for elderly women, whereas they were ≤ 63 cmH2O and ≤ 92 cmH2O for elderly men, and both were identified as predictors of sarcopenia (area under the ROC curve > 0.70). Conclusions: Sarcopenia was associated with lower maximum respiratory pressures, but not with spirometric parameters. Maximum respiratory pressures can be used as markers of sarcopenia in a community-dwelling elderly population regardless of the sex.
