ABSTRACT

Abstract Introduction: Step-based tests are commonly utilized to assess the exercise capacity of individuals with respiratory diseases. However, the feasibility and safety of the step tests have not yet been studied in individuals after COVID-19. Objective: To investigate the feasibility and safety of the six-minute step test (6MST) and the modified incremental step test (MIST) in assessing exercise capacity at home in individuals after hospitalization for COVID-19, and to identify factors associated with performance in these tests. Methods: Cross-sectional multicenter study with individuals hospitalized for COVID-19 fifteen days after hospital discharge. Participants performed spirometry, 6MST, and MIST during a single home visit. Adverse events were registered during and immediately after the tests. Results: Sixty-five participants were studied (50 ± 10 years old, 55% male). The feasibility was 96.9% and the incidence of adverse events was 13.8% in 6MST and 6.2% in MIST. The individuals performed 76.9% of the predicted on the 6MST, with 40% of the participants reaching 80% of the maximum HR and 31% presenting exercise-induced oxygen desaturation. In the MIST, the individuals performed 20% of the predicted, 23% of the participants reached 80% of the maximum heart rate, and 17% presented exercise-induced oxy-gen desaturation. Length of hospital stay and the use of mechanical ventilation were associated with test performance. Conclusion: 6MST and MIST are feasible, safe, and can be used to assess exercise capacity in a home environment in individuals after hospitalization for COVID-19. The performance in these tests was associated with a prolonged hospital stay and the use of mechanical ventilation.


Resumo Introdução: Testes baseados em degraus são comumente utilizados para avaliar a capacidade de exercício de indivíduos com doenças respiratórias. No entanto, a viabilidade e segu-rança dos testes de degrau ainda não foram estudadas em indivíduos após hospitalização por COVID-19. Objetivo: In-vestigar a viabilidade e segurança do teste do degrau de seis minutos (TD6) e do teste do degrau incremental modificado (TDIM) na avaliação da capacidade de exercício no domicílio em indivíduos após hospitalização por COVID-19, e identificar fatores associados ao desempenho nesses testes. Métodos: Estudo transversal multicêntrico com indivíduos internados por COVID-19 quinze dias após a alta hospitalar. Os participantes realizaram espirometria, TD6 e TDIM durante uma única visita domiciliar. Eventos adversos foram registrados durante e ime-diatamente após os testes. Resultados: Foram estudados 65 participantes (50 ± 10 anos, 55% do sexo masculino). A via-bilidade foi de 96,9% e a incidência de eventos adversos foi de 13,8% no 6MST e 6,2% no TDIM. Os indivíduos realizaram 76,9% do previsto no TD6, sendo que 40% dos participantes atingiram 80% da frequência cardíaca máxima e 31% apresen-taram dessaturação de oxigênio induzida pelo exercício. No TDIM, os indivíduos realizaram 20% do previsto, 23% dos participantes atingiram 80% da frequência cardíaca máxima e 17% apresentaram dessaturação de oxigênio induzida pelo exercício. O tempo de internação e o uso de ventilação mecâni-ca estiveram associados ao desempenho do teste. Conclusão: O TD6 e o TDIM são viáveis, seguros e podem ser usados para avaliar a capacidade de exercício em ambiente domiciliar em indivíduos após hospitalização por COVID-19. O desempenho nesses testes esteve associado ao tempo prolongado de internação e ao uso de ventilação mecânica.

ABSTRACT

SUMMARY OBJECTIVE: The objectives of this study were to translate and cross-culturally adapt the telehealth usability questionnaire into Brazilian Portuguese and to evaluate its psychometric properties. METHODS: This was a methodological validation study carried out in two phases. In phase 1, the telehealth usability questionnaire was cross-culturally adapted with 10 participants comprising the expert committee members, including 5 healthcare professionals with theoretical and practical knowledge of telehealth, 1 methodologist, and 4 translators. This phase was performed at Universidade Federal de Juiz de Fora Physiotherapy Clinic School. In phase 2, the psychometric properties of telehealth usability questionnaire Brazil were analyzed. This phase included in-person assessments at Márcio Cunha Hospital, Minas Gerais. The recruitment period for both phases was from April 2020 to February 2021. Content validity, reliability, internal consistency, and criterion validity were analyzed. The criterion validity was evaluated using correlation with a validated instrument: the system usability scale. RESULTS: The telehealth usability questionnaire was adequately translated and cross-culturally adapted. The telehealth usability questionnaire Brazil presented an excellent content validity index of 0.96 with percentages of understanding higher than 90%. The telehealth usability questionnaire Brazil demonstrated great internal consistency (α=0.94 and ω=0.94), excellent intra-rater reliability (intraclass correlation coefficient=0.85, 95%CI 0.75-0.91), no difference between the test and retest [T (0.425), p>0.673], and no proportional bias (p=0.205). There was a moderate correlation between telehealth usability questionnaire Brazil and the system usability scale (r=0.52, p<0.0001). CONCLUSION: The telehealth usability questionnaire was adequately translated and cross-culturally adapted into Brazilian Portuguese and showed adequate psychometric properties for use in telehealth clinical practice and research in Brazilian-Portuguese-speaking individuals.

ABSTRACT

ABSTRACT Objective: To establish normative values and a reference equation for the number of steps climbed during the six-minute step test (6MST) in healthy adults, and to assess the reliability of the test and of the equation. Methods: This was a multicenter cross-sectional study involving 468 healthy volunteers (age range: 18-79 years) recruited from the general community in six research laboratories across different regions of Brazil, which is a country with continental dimensions. The 6MST was performed twice (30-min interval), and clinical, demographic, and functional variables were evaluated. An independent sample of 24 volunteers was evaluated to test the reference equation a posteriori. Results: The number of steps had excellent test-retest reliability (intraclass correlation coefficient = 0.96 [95%CI: 0.95-0.97]), and the mean number of steps was 175 ± 45, the number being 14% greater in males than in females. The best performance on the test was correlated with age (r = −0.60), sex (r = 0.28), weight (r = 0.13), height (r = 0.41), BMI (r = −0.22), waist circumference (r = −0.22), thigh circumference (r = 0.15), FVC (r = 0.54), and physical activity level (r = 0.17; p < 0.05 for all). In the regression analysis, age, sex, height, and weight explained 42% of the variability of the 6MST. Normative values were established for the 6MST according to age and sex. There was no difference between the 6MST values from the independent sample and its predicted values (157 ± 29 steps vs. 161 ± 25 steps; p = 0.47; 97% of predicted values). Conclusions: The normative values and the reference equation for the 6MST in this study seem adequate to accurately predict the physical functional performance in adults in Brazil.


RESUMO Objetivo: Estabelecer valores normativos e uma equação de referência para o número de degraus subidos no teste do degrau de seis minutos (TD6) em adultos saudáveis, bem como avaliar a confiabilidade do teste e da equação. Métodos: Estudo transversal multicêntrico com 468 voluntários saudáveis (faixa etária: 18-79 anos) recrutados na comunidade geral em seis laboratórios de pesquisa em diferentes regiões do Brasil, um país de dimensões continentais. O TD6 foi realizado duas vezes (com 30 min de intervalo entre uma e outra), e foram avaliadas variáveis clínicas, demográficas e funcionais. Uma amostra independente composta por 24 voluntários foi avaliada para testar a equação de referência a posteriori. Resultados: O número de degraus subidos apresentou excelente confiabilidade teste-reteste [coeficiente de correlação intraclasse = 0,96 (IC95%: 0,95-0,97)], e a média de degraus subidos foi de 175 ± 45, sendo 14% maior no sexo masculino. O melhor desempenho no teste correlacionou-se com as seguintes variáveis: idade (r = −0,60), sexo (r = 0,28), peso (r = 0,13), estatura (r = 0,41), IMC (r = −0,22), circunferência da cintura (r = −0,22), circunferência da coxa (r = 0,15), CVF (r = 0,54) e nível de atividade física (r = 0,17; p < 0,05 para todos). Na análise de regressão, idade, sexo, estatura e peso explicaram 42% da variabilidade do TD6. Foram estabelecidos valores normativos para o TD6 de acordo com a idade e o sexo. Não houve diferença entre os valores do TD6 na amostra independente e os valores previstos (157 ± 29 vs. 161 ± 25 degraus subidos; p = 0,47; 97% dos valores previstos). Conclusões: Os valores normativos e a equação de referência para o TD6 neste estudo parecem adequados para predizer com precisão o desempenho físico funcional em adultos no Brasil.

ABSTRACT

ABSTRACT Objective: To investigate the validity of field walking tests to identify exercise-induced hypoxemia and to compare cardiorespiratory responses and perceived effort between laboratory-based and field-based exercise tests in subjects with bronchiectasis. Methods: This was a cross-sectional study involving 72 non-oxygen-dependent participants (28 men; mean age = 48.3 ± 14.5 years; and mean FEV1 = 54.1 ± 23.4% of the predicted value). The participants underwent cardiopulmonary exercise testing (CPET) on a treadmill and constant work-rate exercise testing (CWRET) on the same day (1 h apart). In another visit, they underwent incremental shuttle walk testing (ISWT) and endurance shuttle walk testing (ESWT; 1 h apart). Desaturation was defined as a reduction in SpO2 ≥ 4% from rest to peak exercise. Results: CPET results were compared with ISWT results, as were CWRET results with ESWT results. There was no difference in the magnitude of desaturation between CPET and ISWT (−7.7 ± 6.3% vs. −6.6 ± 5.6%; p = 0.10) and between CWRET and ESWT (−6.8 ± 5.8% vs. −7.2 ± 6.3%; p = 0.50). The incremental tests showed an agreement in the magnitude of desaturation in the desaturation and no desaturation groups (42 and 14 participants, respectively; p < 0.01), as did the endurance tests (39 and 16 participants; p < 0.01). The magnitude of desaturation was similar among the participants who did or did not reach at least 85% of the maximum predicted HR. Conclusions: Field exercise tests showed good precision to detect desaturation. Field tests might be an alternative to laboratory tests when the clinical question is to investigate exercise-induced desaturation in subjects with bronchiectasis.


RESUMO Objetivo: Investigar a validade dos testes de caminhada de campo para identificar dessaturação durante o exercício, comparando os testes de exercício laboratoriais e clínicos de campo quanto às respostas cardiorrespiratórias e percepção de esforço em indivíduos com bronquiectasia não fibrocística. Métodos: Estudo transversal com 72 participantes não dependentes de oxigênio (28 homens; média de idade: 48,3 ± 14,5 anos; média do VEF1: 54,1 ± 23,4% do previsto). Os participantes foram submetidos ao teste de exercício cardiopulmonar (TECP) incremental em esteira e ao constant work-rate exercise testing (CWRET, teste de exercício com carga constante) em esteira, com intervalo de 1 h. Em outra visita, foram submetidos ao incremental shuttle walk test (ISWT, teste de caminhada incremental) e ao endurance shuttle walk test (ESWT, teste de caminhada de resistência), com intervalo de 1 h. A definição de dessaturação foi uma redução da SpO2 ≥ 4% do repouso ao pico do exercício. Resultados: O TECP e o ISWT resultaram em dessaturação de magnitude comparável (−7,7 ± 6,3% vs. −6,6 ± 5,6%; p = 0,10), assim como o fizeram o CWRET e o ESWT (−6,8 ± 5,8% vs. −7,2 ± 6,3%; p = 0,50). Houve concordância entre o TECP e o ISWT quanto ao número de participantes que apresentaram e não apresentaram dessaturação, respectivamente (42 e 14; p < 0,01), bem como entre o CWRET e o ESWT (39 e 16; p < 0,01). A magnitude da dessaturação foi semelhante nos participantes que atingiram ≥ 85% da FC máxima prevista ou não. Conclusões: Os testes de exercício de campo apresentaram boa precisão para detectar dessaturação. Os testes de campo podem ser uma alternativa aos testes de laboratório quando o objetivo é investigar a dessaturação durante o exercício em indivíduos com bronquiectasia.

ABSTRACT

Abstract Aim: This study aimed to compare the performance, metabolic, hemodynamic, and perceived exertion during the 6-minute step test (6MST) conducted with different step heights in healthy subjects and also to compare the performance between different age groups for each step height. The association between age, body mass index, level of physical activity, and lower limb measurements with performance were also evaluated. Methods: This is a cross-sectional study. Anthropometric measures, physical performance, and cardiovascular stress were evaluated during a self-paced 6MST with different step heights in healthy subjects in the age group of 18-59. All the participants underwent three-step tests (15 cm, 20 cm, and 30 cm) on the same day, in a randomized order. Results: Forty participants (20 men and 20 women) performed the tests. The performance in the test for the highest step was significantly lower compared to the step with the lowest height (152 ± 24 vs. 173 ± 27 and 184 ± 33; p < 0,05). The estimated peak oxygen consumption (VO2peak) increased by ∼2.5 mL.kg−1·min−1 with the increase in step height. Hemodynamic variables, such as percent of maximum heart rate (%HRmáx), and systolic blood pressure increased as the step height increased. There was a fair correlation between performance and the level of physical activity in the test with a step height of 15 cm and 20 cm. Conclusion: A higher step height caused greater cardiovascular stress, without exceeding the submaximal levels of the test, indicating that the 6MST can be used as an accurate instrument for evaluating aerobic capacity in healthy individuals.

ABSTRACT

ABSTRACT The performances of healthy individuals in an incremental shuttle walking test performed in a hallway (ISWT-H) and on a treadmill (ISWT-T) were compared to assess their physiological responses during aerobic training sessions with the speeds estimated from both tests. This was a cross-sectional study with 55 healthy subjects, who were randomized to perform the ISWT tests with 24 hours between them. Training sessions were held using a treadmill at 75% of the speeds obtained from the ISWT-H and ISWT-T. Measurements included walking distance, oxygen uptake (VO2), carbon dioxide (VCO2) production, heart rate (HR), and ventilation (VE). There was a significant difference between walking distances (ISWT-T: 823.9±165.2 m and ISWT-H:685.4±141.4 m), but similar physiological responses for VO2 (28.6±6.6 vs. 29.0±7.3 ml-1.kg-1.min-1), VCO2 (1.9±0.7 vs. 1.9±0.5 1), HR (158.3±17.8 vs. 158.6±17.7 bpm), and VE (41.5±10.4 vs. 43.7±12.9 1). The estimated speeds were different for the training sessions (5.5±0.5 km/h and 4.9±0.3 km/h), as well as the VO2, VCO2, VE, and HR. It was concluded that in healthy young adults, ISWTs carried out in a hallway and on a treadmill are not interchangeable. Since the ISWT-H was determined to have lower speed, the training intensity based on this test may underestimate a patient's responses to aerobic training.


RESUMO Comparou-se o desempenho no shuttle walk teste incremental realizado no corredor (SWTI-C) e na esteira (SWTI-E) em indivíduos saudáveis e comparar as respostas fisiológicas durante as sessões de treinamento aeróbio com as velocidades estimadas em ambos os testes. Trata-se de um estudo transversal com cinquenta e cinco participantes saudáveis. Os participantes foram randomizados para realizar os testes com 24 horas de intervalo. As sessões de treinamento foram realizadas na esteira com 75% da velocidade obtida no SWTI-C e no SWTI-E. As avaliações incluíram a distância da caminhada, consumo de oxigênio (VO2), produção de dióxido de carbono (VCO2), frequência cardíaca (FC) e ventilação (VE). Houve uma diferença significante entre as distâncias caminhadas (SWTI-E: 823,9 ± 165,2 m e SWTI-C: 685,4 ± 141,4 m), mas respostas fisiológicas semelhantes para o VO2 (28,6 ± 6,6 vs. 29,0 ± 7,3 ml-1.kg-1.min-1), VCO2 (1,9 ± 0,7 vs. 1,9 ± 0,5 1), HR (158,3 ± 17,8 vs. 158,6 ± 17,7 bpm) e VE (41,5 ± 10,4 vs. 43,7 ± 12,9 1). As velocidades estimadas foram diferentes para as sessões de treinamento (5,5 ± 0,5xkm/h e 4,9 ± 0,3 km/h), assim como o VO2, VCO2, VE e FC. Concluiu-se que em adultos jovens saudáveis, SWTI realizados no corredor e na esteira não são intercambiáveis. Uma vez que o SWTI-E determinou uma menor velocidade, a intensidade do treinamento baseada neste teste pode subestimar as respostas de um paciente ao treinamento aeróbio.


RESUMEN Se trata de una comparación del rendimiento en la prueba incremental shuttle walk llevado a cabo en el pasillo (SWPI-P) y en la cinta caminadora (SWPC) entre individuos sanos, para evaluar las respuestas fisiológicas durante las sesiones de entrenamiento aeróbico con velocidades estimadas en ambas pruebas. Estudio transversal con 55 individuos sanos. A los participantes se les eligieron al azar para realizar las pruebas con intervalo de 24 horas. Se llevaron a cabo sesiones de entrenamiento en la cinta caminadora con el 75 % de la velocidad obtenida en SWPI-P y en SWPC. Se incluyen entre las evaluaciones la distancia de la caminata, el consumo de oxígeno (VO2), la producción de dióxido de carbono (VCO2), la frecuencia cardiaca (FC) y la ventilación (VE). Hubo una diferencia significativa entre las distancias recorridas (SWPC: 823,9 ± 165,2 m y SWPI-P: 685,4 ± 141,4 m), pero similares a las respuestas fisiológicas del VO2 (28,6 ± 6,6 vs. 29,0 ± 7,3 ml-1.kg-1. min-1), VCO2 (1,9 ± 0,7 vs. ± 1,9 0,5 1), HR (158,3 ± 17,8 vs. 158,6 ± 17,7 bpm) y VE (41,5 ± 10,4 vs. 43,7 ± 12,9 1). Las velocidades estimadas fueron diferentes en las sesiones de entrenamiento (5,5 ± 0,5 km/h y 4,9 ± 0,3 km/h), así como VO2, VCO2, VE y FC. Se concluyó que, en los adultos jóvenes sanos, la SWPI llevada a cabo en el pasillo y en la cinta caminadora no pueden ser intercambiables. Dado que la SWPC determinó una menor velocidad, la intensidad de entrenamiento de esta prueba puede subestimar las respuestas de un paciente en el entrenamiento aeróbico.

ABSTRACT

RESUMO A ausência de planejamento e da integração entre as entidades responsáveis pelo gerenciamento da infraestrutura urbana associada à ocupação inadequada do espaço da cidade ocasiona sobrecargas em determinados trechos da rede pluvial. O presente trabalho tem o objetivo de avaliar o desempenho hidráulico do sistema de drenagem de águas pluviais urbanas do Campus Universitário "Professor Zeferino Vaz", de tal forma que sejam identificados quais trechos apresentam sobrecarga e eventualmente inundações locais. Normalmente, em áreas urbanas, os dados hidrológicos disponíveis restringem-se aos dados pluviométricos. Dessa forma, são necessários métodos de transformação de chuva-vazão para o cálculo das vazões afluentes à rede de drenagem. Após a determinação das vazões afluentes, foram avaliadas as condições hidráulicas de operação em regime permanente variado. Por meio de índices de desempenho hidráulico reportados na literatura, foram avaliados graus de sobrecarga em cada trecho da rede de drenagem urbana. Além disso, a elaboração da matriz da contribuição hidráulica da rede de drenagem possibilitou identificar as causas das sobrecargas em cada trecho. As avaliações das redes do campus realizadas com período de retorno de 5 anos mostraram que o campus possui pelo menos 12 pontos de alagamento. Nesse sentido, o índice de desempenho hidráulico e a matriz de contribuições poderão constituir um importante instrumento também para uma eventual reabilitação dessas redes.


ABSTRACT The lack of effective planning and integration between the urban infrastructure administrations associated with the widespread soil development provokes surcharge over the storm sewer pipe network. This work aimed to assess the hydraulic performance of an urban stormwater sewer pipe network located at the main campus of the State University of Campinas, São Paulo, Brazil, in such a manner that it is possible to identify those surcharged reaches and eventually local floods. Since flow rates are not available in urban watersheds, the overland flow was estimated by rainfall-runoff transformation methods. Next, the steady state hydraulic analysis was used to estimate the hydraulic heads in the pipe network. Hydraulic performance index, the ratio of overcharge in each pipe network segment and the hydraulic contribution matrix showed what segments cause each manhole surge. The results for the five-years return period rainfall show that there are at least 12 manhole surge locations in the area, which are vulnerable to local floods. In this sense, the hydraulic performance index and the contribution matrix may be important instruments also for an eventual rehabilitation work to the stormwater sewer pipe network in this area.

ABSTRACT

As doenças sistêmicas crônicas têm maior prevalência nos pacientes idosos, elevando os riscos de morbimortalidade. As alterações do sistema gastrointestinal podem trazer complicações para qualidade de vida destes. O objetivo deste estudo é determinar a prevalência de sintomas gastrointestinais numa amostra de pacientes idosos e a associação com comorbidades e uso de medicações. Metodologia: Foram selecionados 100 pacientes idosos (idade ≥ 60 anos) do Ambulatório do Hospital Evangélico de Curitiba, submetidos a entrevista estruturada e preenchimento de questionário padronizado de sintomas gastrointestinais. Foi analisada a associação com comorbidades, uso de medicamentos e busca de ajuda médica. Os dados coletados foram analisados através do percentual. Resultados: O estudo mostrou uma prevalência de sintomas gastrointestinais em idosos de 78%. A disfagia (37%), plenitude pós prandial (29%) e a constipação intestinal (25%) foram os sintomas esofágico, dispéptico e intestinal mais prevalentes, respectivamente. Dos pacientes sintomáticos, 56,41% procuraram ajuda médica e 53,8% utilizaram medicações sem orientações. A manifestação gastrointestinal mais comum nas mulheres foi plenitude pós prandial e pirose nos homens. Dos pacientes entrevistados, 19 apresentavam diabetes melitus e o sintoma mais prevalente foi a disfagia. As doenças cardiovasculares foram encontrados em 70 pacientes e a manifestação prevalente foi a pirose. As doenças osteomusculares foram encontradas em 42 dos pacientes e o sintoma mais frequente foi a pirose. Conclusão: O presente estudo mostrou que a prevalência de sintomas gastrointestinais é alta na população idosa, assim como apontam outros estudos. As doenças associadas e uso de medicações podem interferir na prevalência de sintomas, mas não foi encontrada em proporção significativa no estudo


The chronic systemic diseases are more prevalent in older patients, increasing the risk of mortality. Changes in gastrointestinal system can bring complications to the quality of life of these. Objectives: To determine the prevalence of gastrointestinal symptoms in a sample of elderly patients and association with comorbidities and use of medications. Methodology: A total of 100 elderly (age ≥ 60 years) patients at the Evangelic Hospital in Curitiba were interviewed and answered a standardized questionnaire with gastrointestinal symptoms. The association with comorbidities such as diabetes mellitus, cardiovascular and musculoskeletal diseases, use of drugs and seeking medical help were researched.

ABSTRACT

In the 30 years of the AIDS pandemic in Brazil, it is recognized the HIV virus internalization of the phenomenon as a challenge to care and current health policies. In this sense, it aimed to verify sex practices and social representations that rural towns residents have about the disease. Attended by 789 people, men and women, between 18 and 90 years old, residents in 41 towns with fewer than 11,000 inhabitants in the state of Paraiba / Brazil. Data were collected by a questionnaire and the free association of words test. The results showed low concern about disease, perception of invulnerability to HIV infection and not using condoms during sexual intercourse, and confidence in the major reason related partner. Also showed endure derogatory and stereotypical representations, revealing that still persist in rural areas, beliefs and representations concerning the beginning of the epidemic. From these findings, it is possible to point out deficiencies in the care provided by the health services in these localities, which may result in increased vulnerability of this population to diseases, so there is the need to intensify information campaigns and intervention. The results reveal the existence of three different types of modes of learning health literacy skills in informal context: : i) learning that takes place in action, in achieving daily tasks; ii) learning processes that result from problem solving; iii) learning that occurs in an unplanned manner, resulting from accidental circumstances and, in some cases, devoid of intentionality.


En los 30 años de pandemia de Sida en Brasil, se reconoce el fenómeno de la interiorización del virus VIH como un desafío al ciudadano y a las políticas de salud actuales. En este sentido, se objetivó conocer a prácticas sexuales y a las representaciones sociales que residentes en ciudades rurales tienen acerca de la enfermedad. Participaron 789 personas, hombres y mujeres, entre 18 y 90 años de edad, residentes en 41 ciudades con menos de 11.000 habitantes en el estado de Paraíba/ Brasil. Los datos fueran recolectados por medio de un cuestionario y el test de asociación libre de palabras. Los resultados demuestran una baja preocupación con la enfermedad, percepción de invulnerabilidad a la contaminación por el VIH y el no uso de preservativos en las relaciones sexuales, siendo la confianza en la pareja la principal razón relacionada. También mostraron perdurar representaciones de naturaleza peyorativa y estereotipada, revelando que aún perduran en el medio rural, creencias y representaciones referentes al inicio de la epidemia. A partir de tales hallados es posible apuntar deficiencias en términos de cuidados ofrecidos por los servicios de salud en estas localidades, lo que puede resultar en mayores vulnerabilidades de esa población a la enfermedad, habiendo así la necesidad de la intensificación de campañas de información e intervención.

ABSTRACT

Objetivo: Analisar as solicitações de transfusões sanguíneas encaminhadas à central transfusional do Hospital Universitário Evangélico de Curitiba, buscando identificar o tipo e quantidade de hemocomponentes transfundidos nesse período, bem como o perfil dos pacientes receptores e as razões pelas quais eles foram submetidos a essa terapia. Material e Métodos: Foram analisadas todas as fichas de requerimento de transfusão encaminhadas à central transfusional do hospital no período de agosto a dezembro de 2013, sendo incluídas no estudo apenas aquelas que resultaram em transfusão efetiva. Foram obtidas informações referentes às características dos pacientes, aos hemocomponentes transfundidos e às indicações relativas a cada um deles. Resultados: A idade média foi de 50 anos, com predominância nos homens (58,7%). De forma geral, foi observado que a maioria dos procedimentos foi realizada na enfermaria (47,7%). O hemocomponente mais transfundido foi o concentrado de hemácias (74,1%). A principal indicação para a transfusão de concentrado de hemácias foi por anemia em paciente com doença cardíaca, pulmonar ou cerebrovascular (51,9%). O tipo sanguíneo predominante na nossa pesquisa foi o O positivo (43%). Conclusão: O fracionamento do sangue total em hemocomponentes levou a um maior benefício clínico para os pacientes que recebem as transfusões, acarretando em um maior número de pacientes atendidos pela terapêutica transfusional e menor desperdício desse material nobre. O hemocomponente mais transfundido foi o concentrado de hemácias, não sendo realizado nenhum procedimento utilizando-se de sangue total. Dentre os procedimentos, apenas 16,4% foram indicados devido a procedimento cirúrgico.


Objective: To analyze the requests for blood transfusions that were sent to the transfusion center of Hospital Universitário Evangélico de Curitiba, seeking to identify the type and amount of blood products transfused during this period as well as the profile of the recipient patients and the reasons why they were subjected to this therapy. Material and Methods: All records of transfusion requests sent to the hospital transfusion center from August 2013 to December of that same year were analyzed, but only those that resulted in effective transfusion were included in the study. Information regarding the characteristics of patients, transfused blood products and indications for each of them were obtained. Results: The mean age was 50 years, predominantly in men (58.7%). In general, we observe that most of the procedures was performed on the ward (47.7%). The most transfused blood component was the red blood cells (74.1%). The main indication for transfusion of red blood cells is anemia in patients with heart, lung or cerebrovascular disease (51.9%). The predominant blood type in our survey was the O positive (43%). Conclusion: The fractionation of whole blood into blood components led to a greater clinical benefit for patients receiving transfusions , resulting in a greater number of patients treated by transfusion therapy and less waste of this noble material. The most transfused blood component was the red blood cells , not being carried out no procedure using whole blood . Among the procedures , only 16.4 % were indicated due to a surgical procedure.

ABSTRACT

Considerando a alta prevalência do Helicobacter pylori e os riscos vinculados à infecção crônica, métodos eficientes para detecção desta bactéria são de extrema importância. Os principais meios diagnósticos invasivos são o teste rápido da urease e o exame anatomopatológico, porém pode haver interferência devido ao uso de inibidores de bomba de prótons (IBP). Nosso objetivo é determinar se o uso dos IBP por pelo menos 7 dias antes das biópsias provoca diminuição da sensibilidade de ambos os testes na detecção do H. pylori. Método: Foram entrevistados 95 pacientes, e excluídos 30. Nos 65 pacientes válidos foi realizado o teste rápido da urease à partir de duas amostras (de antro e de corpo) e o exame histológico foi feito em 49 dos 65 pacientes a partir de biopsia do antro. Os pacientes foram divididos em 2 grupos, o primeiro que fazia uso de IBP e o segundo que não. Os resultados foram submetidos ao teste qui-quadrado sendo considerado relevante um p≤0,05. Resultados: No teste da urease o grupo 1 apresentou 26,92% de positivos enquanto o grupo 2 apresentou 48,71% de positivos. No anatomopatológico o grupo 1 apresentou 31,25% de positivos e o grupo 2 53,33% de positivos. Conclusão: Em nossa pesquisa não foi encontrada diferença significativa entre os dois grupos observados, porém segundo o 3º Consenso Brasileiro para Estudo do Helicobacter pylori e o American College of Gastroenterology é recomendável a suspensão dessas medicações de 7 a 14 dias antes da EDA.


Considering the high prevalence of Helicobacter pylori and the risks related to its chronic infection, efficient ways to detect this bacteria are extremely important. Two of the main invasive exams are the urease test and the histology. However, they seem to be impaired by the use of Proton-pump inhibitors (PPI's). Our aim is to determine if the use of PPI's for at least 7 days before the biopsies can decrease the sensibility of rapid urease testing and histology on detecting H. pylori infection. Methods: 95 patients were interviewed, but only 65 were considered valid or this study. Those valid patients were divided in two groups, one for those in use of PPI's and the other for the remaining patients. The urease teste was applied in all patients based in two biopsies (one form the antrum and other from the body). Only 49 of those patients did the histological exam from a biopsy of the antrum. We applied the chi-square test and considered significant a p≤0,05 Results: Urease test in group 1 showed 26.92% positive while group 2 had 48.71% positive. Pathology group 1 showed 31.25% positive and group 2 53.33% positive. Conclusion: In our study no significant difference was observed between the two groups, but according to the 3rd Brazilian Consensus for Study of Helicobacter pylori and the American College of Gastroenterology is advisable to suspend these medications 7-14 days prior to the EDA.

ABSTRACT

Syagrus romanzoffiana is a palm tree native and widely distributed of South America. The present study investigated the longevity and germination of the buried seeds of this species in an experimental seed bank. Laboratory germination and viability tests were performed for comparison with field results. Pyrenes (seeds enclosed by the endocarp) were buried in a forest fragment edge in July 2012 (dry season) and exhumed monthly during one year, for the assessment of water content and percentage of germinated and viable seeds. Germination tests were conducted in a Mangelsdorf-type germinator at 30°C under constant light and the viability was assessed by the tetrazolium test. An additional sample of pyrenes was buried to evaluate the percentage of seedling emergence and survival. Climatic and soil moisture data were recorded. In the laboratory, the pyrenes were stored for one year in a temperature-controlled room at 20ºC and 75% (±10%) relative air humidity to assess changes in the percentage of germination and viability over time. In the field, a reduction in seed viability was observed over the study period, with a total loss of viability of non-germinated seeds at seven months after burial. The maximum germination (close to 26%) was observed in the samples that were exhumed between five and seven months after burial. In the field, seedling emergence did not exceed 10% and seedling mortality was not observed. The percentages of germination and of viable seeds decreased both in burial and stored seeds. The stored seeds maintained viability at up to six months, with marked reduction thereafter. After the germination tests (four months) in the laboratory, all of the remaining seeds were nonviable. The ecological, physiological and reproductive characteristics of the species are discussed, and we concluded that S. romanzoffiana seeds have short longevity after imbibition, and low potential for soil seed bank formation.

Syagrus romanzoffiana (Arecaceae) es una palma nativa y ampliamente distribuida de América del Sur. El presente estudio investigó la longevidad y la germinación de las semillas enterradas de esta especie en un banco experimental. Se realizaron pruebas de germinación y viabilidad de laboratorio para hacer una comparación con los resultados de campo. Pirenos (semillas encerradas por el endocarpio) fueron enterrados en el borde de un fragmento de bosque en julio (época seca) y exhumados mensualmente por un año, para la evaluación del contenido de agua y del porcentaje de semillas germinadas y viables. Las pruebas de germinación se realizaron en un germinador tipo Mangelsdorf a 30°C bajo luz constante y la evaluación de la viabilidad se realizó con la prueba de tetrazólio. Una muestra adicional de pirenos fue enterrada para evaluar el porcentaje de emergencia de las plántulas. Se tomaron los datos climáticos y se determinó la humedad del suelo. En el laboratorio, los pirenos se almacenaron durante un año en una sala de temperatura controlada a 20°C y 75% (±10%) de humedad relativa del aire, para evaluar los cambios en el porcentaje de germinación y la viabilidad en el tiempo. En el campo, se observó una reducción de la viabilidad de las semillas durante el período de estudio, con una pérdida total de la viabilidad de las semillas no germinadas a los siete meses después del entierro. La germinación máxima (cerca de 26%) se observó en las muestras que fueron exhumadas entre cinco y siete meses después del entierro. En el campo, la emergencia de las plántulas no superó el 10% y no se observó mortalidad de plántulas. Los porcentajes de germinación y de semillas viables disminuyeron tanto en el suelo como en el laboratorio. Las semillas almacenadas mantuvieron la viabilidad hasta por seis meses de almacenamiento, con una reducción marcada a partir de entonces. Después de las pruebas de germinación (cuatro meses) en el laboratorio, todas las semillas restantes eran inviables. Discutimos las características ecológicas, fisiológicas y reproductivas de la especie, y llegamos a la conclusión de que las semillas de S. romanzoffiana tienen corta duración después de la imbibición y bajo potencial de formación del banco de semillas en el suelo.

ABSTRACT

Background: The 6-minute walk test (6MWT) and the Glittre ADL-test (GT) are used to assess functional capacity and exercise tolerance; however, the reproducibility of these tests needs further study in patients with acute lung diseases. Objectives: The aim of this study was to investigate the reproducibility of the 6MWT and GT performed in patients hospitalized for acute and exacerbated chronic lung diseases. Method: 48 h after hospitalization, 81 patients (50 males, age: 52±18 years, FEV1: 58±20% of the predicted value) performed two 6MWTs and two GTs in random order on different days. Results: There was no difference between the first and second 6MWT (median 349 m [284-419] and 363 m [288-432], respectively) (ICC: 0.97; P<0.0001). A difference between the first and second tests was found in GT (median 286 s [220-378] and 244 s [197-323] respectively; P<0.001) (ICC: 0.91; P<0.0001). Conclusion: Although both the 6MWT and GT were reproducible, the best results occurred in the second test, demonstrating a learning effect. These results indicate that at least two tests are necessary to obtain reliable assessments. .

ABSTRACT

Objective: to evaluate the effect of 660nm and 780 nm laser therapy, with dose of 6.3 J/cm² and 25 mW power, either associated with nutritional stress or not, on laryngeal epidermoid carcinoma cell proliferation (H.Ep. 2). Material and Methods: the H.Ep.2 cells were placed in a culture flask and frozen in fetal bovine serum (FBS) at -80°C, with different concentrations of the medium: 5% and 10%. Laser therapy was started 24 h after cell subculturing and performed at time intervals of 6, 12, 24, 48 and 72 hours after the first irradiation, in a period of five days. After this, cell viability was verified using the MTT method. Means and standard deviation were obtained, and the Student's-t and F (ANOVA) statistical tests were used, with Tukey or Tamanhe comparisons. Results: The group subjected to 780 nm laser showed significant differences (p 0.05). The time influenced the growth of all cultures. Conclusion: low level laser interfered in cell proliferation and this effect could be determined by the wavelength used and the nutritional status of the cells.

ABSTRACT

BACKGROUND: Symptoms of fatigue and dyspnea, treatment with oral corticosteroids, high circulating levels of cytokines, and oxidant/antioxidant imbalance in patients hospitalized with community-acquired pneumonia (CAP) could affect the patients' exercise tolerance and peripheral muscle strength (PMS). OBJECTIVE: To evaluate the functional capacity (FC) of patients hospitalized for CAP and to correlate the FC with length of hospital stay. METHOD: We prospectively evaluated 45 patients (49±16 years; CAP group) and 20 healthy subjects (53±17 years; control group). They were randomized to perform, on separate days, a 6-minute walk test (6MWT), a test of PMS, and the Glittre test (GT). Additionally, the SF-36 questionnaire and the MRC scale were completed and evaluated. RESULTS: There were significant differences between the groups (CAP and controls) for the 6MWT (381.3±108 vs. 587.1±86.8 m) and GT (272.8±104.3 vs. 174±39 sec). The CAP group also presented worse health-related quality of life (HRQoL) scores, reduced strength (quadriceps and biceps), and higher scores of dyspnea. The time required to perform the GT correlated with the length of hospital stay (r=0.35, P=0.02) and dyspnea (r=0.36, P=0.02). Significant correlations were observed between GT and 6MWT (r=-0.66, P=0.0001) and between GT with the physical functioning domain of SF-36 (r=-0.51, P=0.0001). CONCLUSIONS: Patients hospitalized for CAP presented with reduced FC, PMS, and HRQoL during hospitalization. In addition, GT performance was related to the length of hospital stay. .

ABSTRACT

INTRODUÇÃO: A Fisioterapia vem atuando com o objetivo de reduzir falhas no desmame da ventilação mecânica (VM) que podem repercutir em desfechos desfavoráveis para o paciente. OBJETIVO: Avaliar os efeitos da fisioterapia no desmame da VM. MATERIAIS E MÉTODOS: Estudo transversal e controlado com pacientes adultos. A formação dos grupos estudados foi resultado de dois períodos ocorridos em uma UTI; em determinado período, a unidade contou com a presença de um profissional de Fisioterapia, em outro, não teve a presença desse profissional por razões administrativas. Registraram-se os resultados do desmame por meio de coleta diária de informações. Foram estudados 50 pacientes, 31 fizeram fisioterapia (grupo fisioterapia, GF) e 19 não fizeram (grupo controle, GC). O GF realizou dois atendimentos diários (quarenta minutos cada), composto das técnicas: compressão do tórax, hiperinsuflação manual, aspiração traqueal e de vias aéreas, movimentação e condução do desmame. O GC recebeu tratamento médico usual. RESULTADOS: Observou-se no GF e GC, respectivamente: sucesso no desmame - 71% (22) e 21% (4) (p = 0,001); tempo de VM - 152 ± 142 e 414 ± 344 horas (p = 0,04); tempo de desmame: 13 ± 48 e 140 ± 122 horas (p < 0,0001); tempo de internação na UTI - 338 ± 192 e 781 ± 621 horas (p = 0,007); tempo de internação hospitalar - 710 ± 628 e 1108 ± 720 horas (p = 0,058); mortalidade: 35% (11) e 47% (9) (p = 0,41). CONCLUSÃO: A fisioterapia esteve associada ao aumento do sucesso no desmame, à redução do tempo de desmame, tempo de VM e de internação na UTI. Não houve diferença no tempo de internação hospitalar e na mortalidade.


INTRODUCTION: Physiotherapy is acting with the aim of reducing failures in weaning from mechanical ventilation (MV), which may impact on unfavorable outcomes. OBJECTIVE: To evaluate the effects of physiotherapy in weaning from MV. MATERIAL AND METHODS: This transversal and controlled study included adult patients. During the duration of the study, for administrative reasons, the ICU has gone through a period without physiotherapy. Daily information was collected from medical records on the outcome of weaning from MV. We studied 50 patients, 31 aided by physiotherapy (physiotherapy group, PG) and 19 without physiotherapy (control group, CG). The PG underwent two sessions daily (forty minutes each). The techniques applied were: chest compression, manual hyperinflation, tracheal and upper airways suctioning, movement and conduct of monitoring and weaning. RESULTS: The results of weaning in PG and CG are respectively: successful weaning: 71% (22) and 21% (4) (p = 0.001), duration of MV: 152 ± 142 and 414 ± 344 hours (p = 0.04), duration of weaning: 13 ± 48 and 140 ± 122 hours (p < 0.0001), length of ICU: 338 ± 192 and 781 ± 621 hours (p = 0.007), length of hospital: 710 ± 628 and 1108 ±720 hours (p = 0.058), mortality 35% (11) and 47% (9) (p = 0.41). CONCLUSION: The physiotherapy in the ICU was associated with increase of the success rate, reducing weaning time, duration of MV, length of stay in ICU. There were no differences in length of hospital stay and mortality.
