Abstract Systemic Arterial Hypertension is a multifactorial clinical condition associated with severe outcomes such as stroke and death. One of the main modifiable risk factor for hypertension is an unhealthy diet, often characterized by the consumption of ultraprocessed foods such as sweetened beverages. We aimed to investigate the relationship between the consumption of sweetened beverages, both sugar-sweetened and artificially sweetened, and the prevalence of hypertension in adults. A cross-sectional, household, population-based study with 1,162 adults from two Brazilian cities were carried out. The consumption of food groups and sweetened beverages was obtained by food frequency questionnaire and other data were self-reported. Weight, height, and waist circumference were measured. The association between sweetened beverages consumption and hypertension was analyzed using Poisson regression models, expressed as Prevalence Ratio. The prevalence of hypertension was 16.7%, with no significant difference between genders. The prevalence of consumption of sweetened beverages was 70.3% in men and 54.6% in women, being significantly higher in men. Women who consumed sugar-sweetened and artificially sweetened beverages 6 to 7 days per week had 92% higher prevalence of hypertension compared to those who did not consume or consumed at a lower frequency. Furthermore, women who consumed artificially sweetened beverages at least 1 time per week had 3.36 times higher prevalence of hypertension. The habitual consumption of sweetened beverages may be an important risk factor for hypertension, especially the consumption of diet beverages, which are often marketed as healthier than sugar-sweetened beverages.

Resumen La Hipertensión Arterial Sistémica es una condición clínica multifactorial asociada a resultados graves como el ictus y la muerte. Uno de los principales factores de riesgo modificables de la hipertensión es una dieta poco saludable, a menudo caracterizada por el consumo de alimentos ultraprocesados como las bebidas endulzadas. Nuestro objetivo fue investigar la relación entre el consumo de bebidas endulzadas, tanto azucaradas como edulcoradas artificialmente, y la prevalencia de hipertensión en adultos. Se realizó un estudio transversal, domiciliario y poblacional con 1,162 adultos de dos ciudades brasileñas. El consumo de grupos de alimentos y bebidas endulzadas se obtuvo mediante cuestionario de frecuencia de alimentos y los demás datos fueron autoinformados. Se midieron el peso, la talla y el perímetro de la cintura. La asociación entre el consumo de bebidas endulzadas y la hipertensión se analizó mediante modelos de regresión de Poisson, expresados como Ratio de Prevalencia. La prevalencia de hipertensión fue del 16,7%, sin diferencias significativas entre géneros. La prevalencia de consumo de bebidas endulzadas fue del 70,3% en los hombres y del 54,6% en las mujeres, siendo significativamente mayor en los hombres. Las mujeres que consumían bebidas azucaradas y edulcoradas artificialmente entre 6 y 7 días a la semana tenían 92% mayor prevalencia de hipertensión que las que no consumían o consumían con una frecuencia menor. Además, las mujeres que consumían bebidas edulcoradas al menos 1 vez por semana tenían una prevalencia de hipertensión 3,36 veces mayor. Así pues, el consumo habitual de bebidas endulzadas puede ser un importante factor de riesgo de hipertensión, especialmente el consumo de bebidas dietéticas, que a menudo se comercializan como más saludables que las bebidas azucaradas.

ABSTRACT Objective: Analyze the effects of high-intensity interval training (HIIT) on cardiometabolic parameters, and cardiorespiratory fitness to compile the most used HIIT training types in adults with spinal cord injury (SCI). Methods: This is a systematic review of searches performed in the electronic databases PubMed / Medline, Science Direct, and Google Scholar. Studies included I) needed to apply HIIT training II) adults with SCI to analyze III) cardiometabolic aspects and cardiorespiratory fitness. Two independent reviewers selected the articles for inclusion, extracted their data, and assessed their methodological quality. Results: 654 studies were found. Thus, 12 studies, 11 pre- and post-intervention, and one control group (CG) with 106 participants were analyzed. Pre- and post-HIITT intervention results revealed significant improvement in cardiorespiratory fitness and cardiometabolic aspects (VO2peak, LDH, HDL, insulin resistance). In addition, GC results revealed significant improvement in cardiorespiratory fitness observed in the intervention group (HIIT) compared to the moderate-low intensity (GC) group. Seven studies used the arm ergometer as the primary exercise modality. Two studies described functional electrical stimulation (FES) performed with the arm ergometer plus electrical stimulation in the lower limbs. None reported heart rate dynamics during the study period. Conclusion: High-intensity interval training improves physical fitness and cardiometabolic health in adults with SCI. Evidence level II; Systematic Review of level II studies.

ABSTRACT Purpose: To compare strip meniscometry and Schirmer tear test 1 results and tear film breakup time between dogs with normal eyes and dogs diagnosed with keratoconjunctivitis sicca. Methods: One-hundred fifty-six eyes of 78 dogs, 88 normal eyes, and 68 eyes diagnosed with keratoconjunctivitis sicca were included in the study. The tests were performed in the following sequence: Schirmer tear test 1 was used to allocate the dogs to the normal or keratoconjunctivitis sicca group, followed by the strip meniscometry test and tear film breakup time measurement. Results: The results (mean ± standard deviation) of the tests in the normal group were as follows: Schirmer tear test 1, 22.75 ± 3.88 mm/min; strip meniscometry test, 10.01 ± 2.35 mm/5 sec; and tear film breakup time, 25.82 ± 5.47 sec. In the keratoconjunctivitis sicca group, the results were as follows: Schirmer tear test 1, 6.10 ± 4.44 mm/min; strip meniscometry test, 3.03 ± 2.62 mm/5 sec; and tear film breakup time, 10.78 ± 4.23 sec. The Spearman correlation coefficient in the keratoconjunctivitis sicca group was very high, with a significant difference between the strip meniscometry test and Schirmer tear test 1 (r=0.848, p<0.001), and moderate and significant between the strip meniscometry test and tear film breakup time (r=0.773, p<0.001). The cutoff for the strip meniscometry test for keratoconjunctivitis sicca was 7.0 mm/5 sec. Keratoconjunctivitis sicca was suspected when the values were <10 mm/5 sec. Conclusions: This study provided strip meniscometry test values from dogs with normal eyes and eyes with keratoconjunctivitis sicca, with high sensitivity and specificity compared with those of the Schirmer tear test 1. In the future, the strip meniscometry test may be another important quantitative test and could complement the gold standard Schirmer tear test for the diagnosis of keratoconjunctivitis sicca in dogs, an excellent animal model for the study of the disease.

RESUMO Objetivo: Comparar o teste de meniscometria em tira com o teste lacrimal de Schirmer 1 e o tempo de ruptura do filme lacrimal, em cães com olhos normais e cães com diagnóstico de ceratoconjuntivite seca. Métodos: Cento e cinquenta e seis olhos de 78 cães, 88 olhos normais e 68 olhos com diagnóstico de ceratoconjuntivite seca. Os testes foram realizados na seguinte sequência: o teste lacrimal de Schirmer 1 foi utilizado para alocar os cães no grupo normal ou no grupo ceratoconjuntivite seca, seguido pelo teste de meniscometria em tira e tempo de ruptura do filme lacrimal. Resultados: As médias e desvios-padrão para os olhos normais foram: teste lacrimal de Schirmer 1 = 22,75 ± 3,88 mm / min; teste de meniscometria em tira = 10,01 ± 2,35 mm / 5 seg; tempo de ruptura do filme lacrimal = 25,82 ± 5,47 seg; e para os olhos do grupo ceratoconjuntivite seca foram: teste lacrimal de Schirmer 1 = 6,10 ± 4,44 mm / min; teste de meniscometria em tira = 3,03 ± 2,62 mm / 5 seg; tempo de ruptura do filme lacrimal = 10,78 ± 4,23 seg. O teste de correlação de Spearman no grupo ceratoconjuntivite seca foi muito alto, com diferença significativa entre teste de meniscometria em tira e teste lacrimal de Schirmer 1 (r=0,848, p<0,001), moderada e significativa entre teste de meniscometria em tira e tempo de ruptura do filme lacrimal (r=0,773, p<0,001). O cut-off para teste de meniscometria em tira para ceratoconjuntivite seca foi identificado em 7,0 mm / 5 seg, valores abaixo de 10 mm / 5 seg podem ser considerados suspeitos para KCS. Conclusões: Este estudo forneceu valores de teste de meniscometria em tira em olhos normais e com ceratoconjuntivite seca em cães, revelando alta sensibilidade e especificidade em comparação com o teste lacrimal de Schirmer 1. No futuro, o teste de meniscometria em tira pode ser outro teste quantitativo importante e pode complementar o teste lacrimal de Schirmer padrão ouro para o diagnóstico de ceratoconjuntivite seca em cães, um excelente modelo animal para o estudo de ceratoconjuntivite seca.

ABSTRACT Toxoplasmosis is an infection of vast worldwide distribution whose etiologic agent is Toxoplasma gondii. This disease can cause problems ranging from mild symptoms to serious conditions, such as encephalitis, miscarriage and blindness. Therefore, it is of utmost importance to perform a diagnosis with reproducible techniques in order to obtain a good prognosis. The aim of this review was to analyze the efficiency of toxoplasmosis diagnostic techniques based on sensitivity and specificity results. Five research platforms in English language were used (Eric, Elsevier, Google Scholar, PubMed and SciELO), which contained data on the diagnosis of toxoplasmosis. The search and selection were performed for studies published prior to June 2021. The search resulted in the inclusion of 13 articles published from 2005 to 2020. The data revealed the use of different samples in the standardization of techniques such as serum, total blood, colostrum and amniotic fluid. The flow cytometry, lateral flow immunoassay and qPCR techniques showed 100% sensitivity, whereas the ELISA, western blotting, qPCR and RE-LAMP techniques achieved 100% specificity. Significantly, the qPCR and LAMP techniques were more accurate when the likelihood ratio was assessed. The meta-analysis identified that ISAGA and western blotting have low sensitivity values and LIASON, ELFA and ELISA, using a silica bioconjugate, also have low specificity values. It was noted that a wide range of methods have high values of sensitivity and specificity. Therefore, the choice of the method will be based on the conditions and its financial viability.

ABSTRACT BACKGROUND: Coronavirus disease 2019 (COVID-19) can damage cardiac tissue by increasing troponin levels and inducing arrhythmias, myocarditis, and acute coronary syndrome. OBJECTIVES: To analyze the impact of COVID-19 on cardiac autonomic control in mechanically ventilated intensive care unit (ICU) patients. DESIGN AND SETTING: This cross-sectional analytical study of ICU patients of both sexes receiving mechanical ventilation was conducted in a tertiary hospital. METHODS: Patients were divided into COVID-19-positive (COVID(+)) and COVID-19-negative (COVID(-)) groups. Clinical data were collected and heart rate variability (HRV) records obtained using a heart rate monitor. RESULTS: The study sample comprised 82 subjects: 36 (44%) in the COVID(-) group (58.3% female; median age, 64.5 years) and 46 (56%) in the COVID(+) group (39.1% females; median age, 57.5 years). The HRV indices were lower than the reference values. An intergroup comparison identified no statistically significant differences in the mean normal-to-normal (NN) interval, standard deviation of the NN interval, or root mean square of successive differences in NN intervals. The COVID(+) group had an increased low frequency (P = 0.05), reduced high frequency (P = 0.045), and increased low frequency/high frequency (LF/HF) ratio (P = 0.048). There was a weak positive correlation between LF/HF and length of stay in the COVID(+) group. CONCLUSION: Patients who received mechanical ventilation had lower overall HRV indices. COVID(+) patients who received mechanical ventilation had lower vagal HRV components. These findings likely indicate clinical applicability, as autonomic control impairments are associated with a greater risk of cardiac death.

SUMMARY OBJECTIVE: This study aimed to assess physicians’ knowledge about human papillomavirus infection and its prevention. METHODS: Descriptive web-based survey with 15 objective questions targeted to physicians affiliated with the Regional Council of Medicine from Rio de Janeiro state, Brazil. Participants were invited by e-mail and the Council social networks, between January and December 2019. RESULTS: The study sample had 623 participants, with a median age of 45 years, predominantly women (63%). The most frequent specialties were Obstetrics and Gynecology (21.1%), Pediatrics (11.2%), and Internists (10.5%). Concerning human papillomavirus knowledge, 27.9% of the participants were able to identify accurately all possible forms of transmission, and none of them could recognize all the risk factors of infection. Nevertheless, 95% recognized that asymptomatic infection could occur in both sexes. Regarding knowledge about clinical manifestations, diagnosis, and screening, only 46.5% were able to identify all human papillomavirus-related cancers, 42.6% were aware of the periodicity of Pap smears, and 39.4% indicated that serological test was not adequate for diagnosis. The recommended age group for human papillomavirus vaccination was recognized by 94% of the participants, as well as the need for a Pap smear and the use of condoms, even after vaccination. CONCLUSIONS: There is good knowledge about prevention and screening for human papillomavirus infections; many gaps were identified regarding transmission, risk factors, and associated diseases among physicians in Rio de Janeiro state.

ABSTRACT Congenital and gestational syphilis are increasingly prevalent multisystemic infections in Brazil. This study aimed to present a case series of three children diagnosed with congenital syphilis even though their mother had unreactive treponemal tests. The VDRL (Venereal Disease Research Laboratory) titers of a 22-year-old mother with three pregnancies decreased after treatment. The mother did not have a reactive treponemal test, but all the three children were diagnosed with early congenital syphilis. This case series highlights the difficulty in diagnosing gestational and congenital syphilis in Brazil.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract: En | Text: En | PDF: En

Abstract Oral candidiasis is a common fungal infection that affects the oral mucosa, and happens when Candida albicans interacts with bacteria in the oral microbiota, such as Streptococcus mutans, causing severe early childhood caries. C. albicans and S. mutans mixed biofilms are challenging to treat with conventional antimicrobial therapies, thus, new anti-infective drugs are required. Objective This study aimed to test a drug delivery system based on chitosan microparticles loaded with geranium and lemongrass essential oils to inhibit C. albicans and S. mutans mixed biofilms. Methodology Chitosan microparticles loaded with essential oils (CM-EOs) were obtained by spray-drying. Susceptibility of planktonic were performed according CLSI at 4 to 2,048 µg/mL. Mixed biofilms were incubated at 37ºC for 48 h and exposed to CM-EOs at 256 to 4,096 µg/mL. The antimicrobial effect was evaluated using the MTT assay, with biofilm architectural changes analyzed by scanning electron microscopy. RAW 264.7 cell was used to evaluate compound cytotoxicity. Results CM-EOs had better planktonic activity against C. albicans than S. mutans. All samples reduced the metabolic activity of mixed C. albicans and S. mutans biofilms, with encapsulated oils showing better activity than raw chitosan or oils. The microparticles reduced the biofilm on the slides. The essential oils showed cytotoxic effects against RAW 264.7 cells, but encapsulation into chitosan microparticles decreased their toxicity. Conclusion This study demonstrates that chitosan loaded with essential oils may provide an alternative method for treating diseases caused by C. albicans and S. mutans mixed biofilm, such as dental caries.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

ABSTRACT Purpose: To evaluate the viability of the porcine vas deferens as a realistic microsurgical training model for vasectomy reversal Methods: The model uses swine testicles (vas deferent), which are usually discarded in large street markets since they are not part of Brazilian cuisine. The spermatic cord was carefully dissected, and the vas deferens were isolated, measuring 10 cm in length. A paper quadrilateral with 5 cm2 was built to delimit the surgical training field. The objective of the model is to simulate only the microsurgical step when the vas deferens are already isolated. The parameters analyzed were: feasibility for reproducing the technique, patency before and after performing the vasovasostomy, cost of the model, ease of acquisition, ease of handling, execution time, and model reproducibility. Results: The simulator presented low cost. All models made were viable with a texture similar to human, with positive patency obtained in 100% of the procedures. The internal and external diameters of the vas deferens varied between 0.2-0.4 mm and 2-3 mm, respectively, with a mean length of 9 ± 1.2 cm. The total procedure time was 43.28 ± 3.22 minutes. Conclusions: The realistic model presented proved to be viable for carrying out vasectomy reversal training, due to its low cost, easy acquisition, and easy handling, and providing similar tissue characteristics to humans.

RESUMO No contexto de um programa de restauração florestal em área de mineração na Amazônia oriental brasileira, o objetivo deste estudo foi identificar a espécie de abiu-seringarana (Ecclinusa sp.) em remanescentes florestais adjacentes à mina. Como a identificação de Ecclinusa com base apenas na morfologia externa é difícil, ela foi corroborada por análise molecular. Amostras de folhas de três árvores foram comparadas com Ecclinusa no acervo do herbário da Embrapa. O DNA extraído seguiu um protocolo CTAB modificado, e o sequenciamento foi com marcadores ITS. Tanto a identificação morfológica quanto o alinhamento das sequências obtidas com material do GenBank indicaram que os indivíduos pertencem a Ecclinusa guianensis, que é confirmada como a espécie que ocorre na área de mineração. brasileira abiuseringarana abiu seringarana sp. sp mina difícil molecular Embrapa modificado ITS guianensis

ABSTRACT In the context of a forest restoration program in a mining area in the eastern Brazilian Amazon, the objective of this study was to identify the species of trees of abiu-seringarana (Ecclinusa sp.) in forest remnants adjacent to the mine. As the identification of Ecclinusa based on external morphology alone is difficult, it was corroborated by molecular analysis. Leaf samples of three trees were compared with Ecclinusa in the Embrapa herbarium collection. DNA was extracted with a CTAB modified protocol for sequencing with ITS markers. Both the morphological identification and the alignment of the obtained sequences with material in GenBank indicated that the individuals belong to Ecclinusa guianensis, which is confirmed as the species occurring in the mining area.

ABSTRACT This study aimed to evaluate the social and professional profile and knowledge of Primary Care professionals on maternal and child health. Cross-sectional descriptive study, from May to July 2018. It included 30 nurses and 73 Community Health Workers (CHW) from the municipality of Bragança, Pará. The form had three phases: participants’ profile; close-ended questions on their profile, knowledge and resourcefulness on the First Week of Integral Care guideline; and four open-ended questions. Quantitative data was analyzed through Microsoft Office ExcelTM 2016, as qualitative data was arranged through word clouds and similarity trees in IRaMuTeQTM. The majority of nurses and CHW were female (70.9%) and worked in urban areas (60.2%), as 40% of nurses were graduated recently, with an 80% specialization courses, and 83.6% CHW had completed high school. On both categories, 82.5% did not know the First Week of Integral Health guideline, although the word clouds and similarity trees had shown that several national standardized orientations were provided. First Week of Integral Care guidelines’ insufficient knowledge by nurses and CHW in the municipality points to fragility in Primary Care on maternal and child health. Although basic orientations are provided, improvement is necessary.

RESUMO Este estudo buscou avaliar o perfil socioprofissional e o conhecimento de profissionais da atenção primária sobre saúde materno-infantil. É um estudo transversal descritivo, realizado de maio a julho de 2018. Incluiu 30 enfermeiros e 73 Agentes Comunitários de Saúde (ACS) do município de Bragança, Pará. O formulário possuiu três fases: perfil dos participantes; perguntas fechadas sobre perfil, conhecimento e habilidade sobre a diretriz Primeira Semana de Saúde Integral; e quatro perguntas abertas. Os dados quantitativos foram analisados por meio do Microsoft Office ExcelTM 2016, enquanto os dados qualitativos foram organizados por meio de nuvens de palavras e árvores de similaridades no IRaMuTeQTM. A maioria dos enfermeiros e ACS eram mulheres (70.9%) e trabalhavam em áreas urbanas, enquanto 40% dos enfermeiros formaram-se recentemente, sendo 80% por cursos de especialização; 83% dos ACS possuíam ensino médio completo. Em ambas as categorias, 82.5% não conheciam a diretriz da Primeira Semana de Saúde Integral, embora as nuvens de palavras e as árvores de similaridade tenham mostrado que várias orientações padronizadas nacionalmente eram fornecidas. O conhecimento insuficiente da diretriz Primeira Semana de Saúde Integral por parte dos ACS e enfermeiros do município indica a fragilidade da atenção básica na saúde materno-infantil. Ainda que sejam fornecidas orientações básicas, há necessidade de melhora na qualidade do serviço.

ABSTRACT This cross-sectional study aimed to evaluate the autonomic response of older women in the six-minute walk test. In total, 32 women aged 60 years or older without a diagnosed health problem were evaluated during the six-minute walk test. To monitor the autonomic response, the following variables were considered: heart rate, systolic and diastolic blood pressure, respiratory rate, and perceived exertion. These variables were compared during rest, effort, and recovery. This study also sought a correlation between autonomic function variables and performance in the test and perceived exertion. Results showed that the effort made by older women in the six-minute walk test induces an autonomic response resulting in increased heart rate and systolic and diastolic blood pressure; however, the respiratory rate remained unchanged during the test. Diastolic blood pressure remained high during recovery. No correlation was found neither between perceived exertion and cardiovascular physiological response nor between distance covered and variation of the autonomic response or level of physical conditioning. Therefore, the effort spent in the six-minute walk test promotes an autonomic response in older women, increasing cardiovascular stress without increasing ventilation. In this context, the Borg scale was not representative of cardiovascular stress during the test.

RESUMEN El objetivo de este estudio fue investigar la respuesta autonómica de ancianas al esfuerzo en la prueba de paso de 6 minutos (6MWT). Se realizó un estudio transversal con la participación de 32 ancianas, de 60 años o más, sin problemas de salud diagnosticados durante la 6MWT. Para monitorear la respuesta autonómica, se consideraron las siguientes variables: frecuencia cardíaca, presión arterial sistólica y diastólica, frecuencia respiratoria y esfuerzo percibido. Se compararon estas variables durante el período de reposo, esfuerzo y recuperación. También se buscó una correlación entre las variables de función autonómica y rendimiento en la prueba y el esfuerzo percibido. Los resultados mostraron que el esfuerzo producido en la 6MWT genera una respuesta autonómica que conduce a un aumento de la frecuencia cardíaca y de la presión arterial sistólica y diastólica en las mujeres, pero la frecuencia respiratoria se mantuvo sin cambios durante la prueba. La presión arterial diastólica se mantuvo alta durante el período de recuperación. No hubo correlación entre el esfuerzo percibido y la respuesta fisiológica cardiovascular presentada, tampoco entre la distancia recorrida y la variación de la respuesta autonómica o el nivel de condicionamiento físico. Se concluyó que el esfuerzo realizado en la 6MWT generó una respuesta autonómica en las ancianas al intensificar el estrés cardiovascular pero sin aumentar la ventilación. En este contexto, la escala de Borg no fue significativa para el estrés cardiovascular durante la prueba.

RESUMO O objetivo deste estudo foi investigar a resposta autonômica de idosas ao esforço do teste de caminhada de 6 minutos (TC6M). Realizou-se um estudo transversal a partir da avaliação de 32 idosas, sem problemas de saúde diagnosticados, com 60 anos ou mais, durante o TC6M. Para o monitoramento da resposta autonômica, foram consideradas as seguintes variáveis: frequência cardíaca, pressão arterial sistólica e diastólica, frequência respiratória e percepção de esforço. Essas variáveis foram comparadas durante o período de repouso, esforço e recuperação. Buscou-se também correlação entre as variáveis da função autonômica e o desempenho no teste e a percepção de esforço. Os resultados demonstraram que o esforço gerado no TC6M induz uma resposta autonômica que leva ao aumento da frequência cardíaca e da pressão arterial sistólica e diastólica em mulheres, porém a frequência respiratória permaneceu inalterada durante o teste. A pressão arterial diastólica permaneceu elevada durante a recuperação. Não houve correlação entre a percepção de esforço e a resposta fisiológica cardiovascular apresentada, nem entre a distância percorrida e a variação da resposta autonômica ou o nível de condicionamento físico. Concluiu-se que o esforço despendido no TC6M promove uma resposta autonômica em idosas, intensificando o estresse cardiovascular sem aumentar a ventilação. Nesse contexto, a escala de Borg não foi representativa do estresse cardiovascular durante o teste.
