ABSTRACT

OBJECTIVE: The study aimed to investigate whether peripheral and inspiratory muscle strength and architecture, functional capacity, functional mobility, fatigue, and health-related quality of life are predictors of the Post-COVID-19 Functional Status Scale score in patients with post-COVID-19 syndrome who were hospitalized. DESIGN: A cross-sectional study included 69 patients (53.3 ± 13.2 yrs, 36 men) with post-COVID-19 syndrome. The following outcomes were assessed: peripheral (dynamometry) and inspiratory (manovacuometry) muscle strength, muscle architecture (ultrasound), functional capacity (six-minute walk test), functional mobility (Timed Up and Go), fatigue (Functional Assessment of Chronic Illness Therapy), health-related quality of life (36-item Short-Form Health Survey), and functional status (Post-COVID-19 Functional Status scale). RESULTS: Functional mobility (ß = 0.573, P < 0.001), vastus intermedius echogenicity (ß = -0.491, P = 0.001), length of stay (ß = 0.349, P = 0.007), and female sex (ß = 0.415, P = 0.003) influenced the Post-COVID-19 Functional Status Scale. CONCLUSIONS: Functional mobility, muscle quality of the vastus intermedius, length of stay, and female sex influence the Post-COVID-19 Functional Status Scale score in this population. It is noteworthy that functional mobility is an independent predictor of Post-COVID-19 Functional Status Scale.

ABSTRACT

BACKGROUND: Evidence has shown that patients with chronic obstructive pulmonary disease present significant deficits in the control of postural balance when compared to healthy subjects. In view of this, it is pertinent to investigate the effects of different therapeutic strategies used alone or in association with pulmonary rehabilitation with the potential to improve postural balance and other outcomes with clinical significance in patients with chronic obstructive pulmonary disease. This study will investigate the effects of an 8-week (short-term) multimodal exercise program [inspiratory muscle training (IMT) plus neuromuscular electrical stimulation (NMES)] on postural balance in patients with chronic obstructive pulmonary disease enrolled in a pulmonary rehabilitation program compared to individualized addition of IMT or NMES to pulmonary rehabilitation or standard pulmonary rehabilitation. METHODS: This is a randomized, single-blind, 4-parallel-group trial. Forty patients with chronic obstructive pulmonary disease will be included prospectively to this study during a pulmonary rehabilitation program. Patients will be randomly assigned to one of four groups: multimodal exercise program (IMT + NMES + pulmonary rehabilitation group) or (IMT + pulmonary rehabilitation group) or (NMES + pulmonary rehabilitation group) or standard pulmonary rehabilitation group. Patients will receive two sessions per week for 8 weeks. The primary outcome will be static postural balance and secondary outcomes will include as follows: static and dynamic postural balance, fear of falling, muscle strength and endurance (peripheral and respiratory), functional capacity, health-related quality of life, muscle architecture (quadriceps femoris and diaphragm), and laboratory biomarkers. DISCUSSION: This randomized clinical trial will investigate the effects of adding of short-term multimodal exercise program, in addition to pulmonary rehabilitation program, in postural balance in patients with chronic obstructive pulmonary disease enrolled in a pulmonary rehabilitation. Furthermore, this randomized control trial will enable important directions regarding the effectiveness of short-term intervention as part of the need to expand the focus of pulmonary rehabilitation to include balance management in chronic obstructive pulmonary disease patients which will be generated. TRIAL REGISTRATION: ClinicalTrials.gov NCT04387318. Registered on May 13, 2020.

ABSTRACT

RESUMO Os efeitos da adição da estimulação elétrica funcional (EEF) ao treinamento aeróbico e resistido (treino combinado) de curto prazo em pacientes submetidos à cirurgia de revascularização do miocárdio (CRM) ainda não foram estabelecidos. O objetivo do presente estudo é avaliar o impacto da adição da EEF ao treino combinado no fluxo arterial periférico, na capacidade funcional e na qualidade de vida de pacientes pós-CRM participantes de um programa de reabilitação cardíaca - Fase II. Trata-se de um ensaio clínico randomizado, duplo cego, composto por 17 pacientes (54,8±10,5 anos, 12 homens) randomizados ou em grupo intervenção (GI, n=8,) submetido à EEF no músculo quadríceps associada ao treino combinado, ou em grupo sham (GS, n=9), que realizou a EEF sham em associação ao treino combinado. Os desfechos avaliados foram: fluxo arterial periférico (índice tornozelo-braquial), capacidade funcional (distância percorrida no teste de caminhada de seis minutos - DTC6M) e qualidade de vida (questionário MacNew). Na comparação entre os grupos, o aumento do índice tornozelo-braquial (GI: 0,14±0,08 mmHg vs. GC: 0,05±0,04 mmHg; p=0,020) e do escore do domínio global do questionário MacNew (GI: 1,1±0,3 pontos vs. GC: 0,6±0,4 pontos; p=0,020) foi maior no GI. Entretanto, não foi observada diferença entre os grupos para a DTC6M (GI: 130,9±73,7 m vs. GS: 73,7±32,6 m; p=0,072). A adição da EEF, durante curto período, potencializou os efeitos do exercício aeróbico e resistido sobre o fluxo arterial periférico e a qualidade de vida em pacientes pós CRM em Fase II da reabilitação cardíaca.


RESUMEN Aún no se han establecido los efectos de agregar estimulación eléctrica funcional (EPS) cortoplacista al entrenamiento aeróbico y de resistencia (entrenamiento combinado) en pacientes sometidos a cirugía de injerto de derivación de las arterias coronarias (CABG). El objetivo del presente estudio fue evaluar el impacto de la adición de EPS al entrenamiento combinado sobre el flujo arterial periférico, la capacidad funcional y la calidad de vida de los pacientes post-CABG que participan en un programa de rehabilitación cardíaca de Fase II. Este es un ensayo clínico aleatorizado, doble ciego, compuesto por 17 pacientes (54,8±10,5 años, 12 hombres) aleatorizados en un grupo de intervención (GI, n=8) sometidos a EEF en el músculo cuádriceps asociado a entrenamiento combinado o en grupo simulado (GS, n=9), que realizó el simulacro de EEF en asociación con el entrenamiento combinado. Los resultados evaluados fueron: flujo arterial periférico (índice tobillo braquial), capacidad funcional (distancia recorrida en la prueba de caminata de seis minutos - 6MWT) y calidad de vida (cuestionario MacNew). Al comparar los grupos, el aumento del índice tobillo braquial (GI: 0,14±0,08 mmHg vs. GC: 0,05±0,04 mmHg; p=0,020) y la puntuación para el dominio global del cuestionario MacNew (GI: 1,1±0,3 puntos vs. GC: 0,6±0,4 puntos; p=0,020) fueron mayores en el GI. Sin embargo, no hubo diferencias entre los grupos en la 6MWT (GI: 130,9±73,7 m vs. GS: 73,7±32,6 m; p=0,072). La adición de EEF, durante un período corto, potenció los efectos del ejercicio aeróbico y de resistencia sobre el flujo arterial periférico y la calidad de vida en pacientes post-CABG en la Fase II de rehabilitación cardíaca.


ABSTRACT The effects of adding functional electrical stimulation (FES) to short-term aerobic and resistance exercise (combined training) in patients undergoing coronary artery bypass graft (CABG) surgery have not yet been established. This study aims to evaluate the effect of adding FES to combined training on peripheral arterial flow, functional capacity and quality of life of post-CABG patients participating in a cardiac rehabilitation program - Phase II. This is a randomized, double-blind, clinical trial, composed of 17 patients (54.8±10.5 years old, 12 men) randomized or in an intervention group (IG, n=8,) submitted to FES in the quadriceps muscle associated with combined training, or in a sham group (SG, n=9), which performed the FES sham in association with the combined training. The evaluated outcomes were: peripheral arterial flow (ankle-brachial index), functional capacity (distance covered in the six-minute walk test - 6MWT) and quality of life (MacNew questionnaire). In the comparison between the groups, the increase in the ankle-brachial index (IG: 0.14±0.08mmHg vs. CG: 0.05±0.04mmHg; p=0.020) and the score of the global MacNew questionnaire (IG: 1.1±0.3 points vs. CG: 0.6±0.4 points; p=0.020) was higher in the IG. However, no difference was observed between the groups for the 6MWT (IG: 130.9±73.7m vs SG: 73.7±32.6m; p=0.072). The addition of FES, during a short period, potentiated the effects of aerobic and resistance exercise on peripheral arterial flow and quality of life in patients after CABG in Phase II of cardiac rehabilitation.

ABSTRACT

Expiratory positive airway pressure (EPAP) is widely applicable, either as a strategy for pulmonary reexpansion, elimination of pulmonary secretion or to reduce hyperinflation. However, there is no consensus in the literature about the real benefits of EPAP in reducing dynamic hyperinflation (DH) and increasing exercise tolerance in subjects with chronic obstructive pulmonary disease (COPD). To systematically review the effects of EPAP application during the submaximal stress test on DH and exercise capacity in patients with COPD. This meta-analysis was performed from a systematic search in the PubMed, EMBASE, PeDRO, and Cochrane databases, as well as a manual search. Studies that evaluated the effect of positive expiratory pressure on DH, exercise capacity, sensation of dyspnea, respiratory rate, peripheral oxygen saturation, sense of effort in lower limbs, and heart rate were included. GRADE was used to determine the quality of evidence for each outcome. Of the 2,227 localized studies, seven studies were included. The results show that EPAP did not change DH and reduced exercise tolerance in the constant load test. EPAP caused a reduction in respiratory rate after exercise (- 2.33 bpm; 95% CI: - 4.56 to - 0.10) (very low evidence) when using a pressure level of 5 cmH2O. The other outcomes analyzed were not significantly altered by the use of EPAP. Our study demonstrates that the use of EPAP does not prevent the onset of DH and may reduce lower limb exercise capacity in patients with COPD. However, larger and higher-quality studies are needed to clarify the potential benefit of EPAP in this population.

ABSTRACT

ABSTRACT This study aims to assess the effect of short-time low frequency inspiratory muscle trainer (Threshold IMT) on inspiratory muscle strength and electromyographic activity of the sternocleidomastoid (SCM) muscle in people with chronic obstructive pulmonary disease (COPD). People with COPD participating in a lung rehabilitation program were allocated to a control or inspiratory muscle training (IMT) group. The control group participated in the usual rehabilitation, whereas the other group received IMT (performed with a load of 50% maximal inspiratory pressure (MIP) adjusted weekly). Both interventions lasted for 2 months. Outcomes included electromyographic analysis of the SCM and MIP. In total, ten participants were allocated to each group. The IMT group presented an increase in absolute (p<0.001) and predicted (p<0.001) values of MIP and also in pre- and post-intervention variation between groups (p=0.003 and p=0.008, respectively). Such differences were not found in the control group. The SCM muscle activity decreased in the IMT post intragroup evaluation (p=0.008). IMT provided a reduction of the electromyographic activity of SCM in COPD patients, also increasing inspiratory muscle strength in the study participants.


RESUMO O objetivo deste estudo foi avaliar o efeito do treinamento muscular inspiratório de baixa frequência de curta duração (Threshold TMI) na força muscular inspiratória e na atividade eletromiográfica do músculo esternocleidomastoideo (ME) em pessoas com doença pulmonar obstrutiva crônica (DPOC). Pessoas com DPOC que participam de um programa de reabilitação pulmonar foram alocadas em um grupo controle ou de treinamento muscular inspiratório (TMI). O grupo controle participou da reabilitação habitual, enquanto o grupo TMI também recebeu TMI, com carga de 50% da pressão inspiratória máxima (PImáx) ajustada semanalmente. Ambas as intervenções duraram 2 meses. Os resultados incluíram análise eletromiográfica do SCM e PImáx. Dez participantes foram alocados para o grupo controle e 10 para o grupo TMI. O grupo com TMI apresentou um aumento na PImáx nos valores absoluto (p<0,001) e previsto (p<0,001) e na variação pré e pós-intervenção entre os grupos (p=0,003 e p=0,008, respectivamente). Tais diferenças não foram encontradas no grupo controle. A atividade muscular do ME diminuiu no TMI após avaliação intragrupo (p=0,008). O TMI proporcionou redução da atividade eletromiográfica do ME em pacientes com DPOC, além de aumentar a força muscular inspiratória nos participantes do estudo.


RESUMEN El presente estudio tuvo como objetivo evaluar el efecto del entrenamiento muscular inspiratorio de baja frecuencia a corto plazo (Threshold TMI) sobre la fuerza muscular inspiratoria y la actividad electromiográfica del músculo esternocleidomastoideo (ME) en personas con enfermedad pulmonar obstructiva crónica (EPOC). Las personas con EPOC que participan en un programa de rehabilitación pulmonar se asignaron a un grupo control o de entrenamiento muscular inspiratorio (EMI). El grupo control participó en la rehabilitación habitual, mientras que el grupo de EMI también recibió EMI, con una carga del 50% de la presión inspiratoria máxima (PImáx) ajustada semanalmente. Ambas intervenciones tuvieron 2 meses de duración. Los resultados incluyeron el análisis electromiográfico de SCM y PImáx. Se asignaron 10 participantes al grupo control y 10 al grupo de EMI. El grupo de EMI tuvo un aumento de la PImáx en los valores absoluto (p<0,001) y predicho (p<0,001) y en la variación pre y posintervención entre grupos (p=0,003 y p=0,008, respectivamente). No se encontraron estas diferencias en el grupo control. La actividad muscular del ME disminuyó en el EMI después de la evaluación intragrupal (p=0,008). El EMI redujo la actividad electromiográfica del ME de pacientes con EPOC, además aumentó la fuerza muscular inspiratoria en los participantes del estudio.

ABSTRACT

Justificativa e Objetivos: A manutenção do desenvolvimento normal e a maturação do Sistema Nervoso Central do recém-nascido, no primeiro ano de vida, associado às condições ambientais nas quais está inserido, justificam a relevância científica desta pesquisa. Nosso objetivo foi descrever a influência de fatores estressores sobre os sinais vitais de recém-nascidos hospitalizados na Unidade de Tratamento Intensivo Neonatal de um hospital de ensino. Método: Estudo transversal com amostragem de conveniência. Os participantes foram observados nos momentos identificados como sendo de maior e de menor exposição a fatores estressores, sendo registrados níveis de pressão sonora, iluminância, quantidade de procedimentos, presença de dor, além dos indicadores de sinais vitais expressos pelo monitor do paciente. Resultados: Treze neonatos predominantemente prematuros moderados, de baixo peso, nascidos de parto cesárea, com média de idade de 8,0 ± 5,9 dias, preponderância feminina e respirando sob ar ambiente foram avaliados. Notou-se que ambos os fatores estressores provocaram aumento significativo da frequência cardíaca (pressão sonora: p=0,001, Iluminância: p<0,001, procedimentos: p=0,002), ocorrendo o mesmo com a frequência respiratória (pressão sonora: p<0,001, Iluminância: p=0,022, procedimentos: p<0,001) e escore obtido na Escala de Avaliação da Dor Neonatal (pressão sonora: p=0,001, Iluminância: p=0,016, procedimentos: p<0,003), além de redução da saturação periférica de oxigênio (pressão sonora: p=0,011, Iluminância: p=0,024, procedimentos: p<0,016), quando comparados os períodos de maior e de menor exposição. Conclusão: Nossos achados demonstraram o impacto negativo de fatores ambientais e sua influência sobre os sinais vitais de recém-nascidos hospitalizados.(AU)


Background and Objectives: The maintenance of regular development and maturation of the Central Neural System of the neonate in the first year, associated to the environmental conditions in which he is inserted, justify the scientific relevance of this research. Our objective was to describe the influence of stressful factors on hospitalized neonates in the Neonatal Intensive Care Unit of a teaching hospital. Methods: Cross-sectional study with convenience sampling. The participants were observed in moments that were identified as being of more and less exposition to stress factors, in which the sound pressure, illuminance, quantity of procedures, presence of pain, besides the indicators of vital signs expressed by the patient's monitor were registered. Results: Thirteen neonates, predominantly moderate premature babies of low weight, of c-section birth, average age of 8.0 ± 5.9 days, mostly female and breathing room air were evaluated. We noted that stress factors produced significant increase of the heart rate (sound pressure: p=0.001, illuminance: p<0.001, procedures: p=0.022), occurring the same with the respiratory rate (sound pressure: p<0.001, illuminance: p=0.022, procedures: p<0.001) and score obtained in the Neonatal Pain Evaluation Scale (sound pressure: p=0.001, illuminance: p=0.016, procedures: p<0.003), besides the reduction of peripheral oxygen saturation (sound pressure: p=0.011, illuminance: p=0.024, procedures: p<0.016), when compared to the periods of higher and lower exposition. Conclusion: Our findings demonstrated the negative impact of the environmental factors and its influence on the vital signs of hospitalized neonates.(AU)

ABSTRACT

RESUMO O objetivo deste estudo foi avaliar os efeitos do exercício passivo precoce em cicloergômetro na espessura muscular (EM) do quadríceps femoral (EMQ) de pacientes críticos admitidos em uma Unidade de Terapia Intensiva (UTI) de um hospital universitário terciário. O método utilizado foi um estudo-piloto randomizado controlado conduzido em uma amostra de 24 pacientes (51±18,11 anos, 16 do sexo masculino), com 24 a 48 horas de ventilação mecânica (VM), aleatoriamente divididos em dois grupos: grupo-controle (n=12), que recebeu a fisioterapia convencional; e grupo-intervenção (n=12), que recebeu o exercício passivo em cicloergômetro, uma vez ao dia, durante o período de sete dias do protocolo, em adição à fisioterapia convencional. A EMQ foi mensurada através da ultrassonografia. A primeira medida ultrassonográfica foi realizada entre as primeiras 48 horas de VM e a segunda ao término do protocolo. Não houve diferenças significativas na EMQ esquerda (27,29±5,86mm vs. 25,95±10,89mm; p=0,558) e direita (24,96±5,59mm vs 25,9±9,21mm; p=0,682) do grupo-controle e na EMQ esquerda (27,2±7,38mm vs 29,57±7,89mm; p=0,299) e direita (26,67±8,16mm vs 28,65±8,04mm; p=0,381) do grupo-intervenção. Na comparação entre os grupos, não houve alterações significativas em relação à EMQ esquerda (3,61±1,07mm; p=0,248) e a EMQ direita (2,75±0,85mm; p=0,738). Os resultados deste estudo-piloto demonstraram que a aplicação precoce do exercício passivo em cicloergômetro não promoveu mudanças significativas na espessura da camada muscular avaliada. No entanto, nossos achados sinalizam que a fisioterapia convencional foi capaz de preservar a EMQ de pacientes críticos admitidos em UTI.


RESUMEN El presente estudio tuvo como objetivo evaluar los efectos del ejercicio pasivo precoz en cicloergómetro en el espesor muscular (EM) del cuádriceps femoral (EMC) de pacientes críticos ingresados en una Unidad de Cuidados Intensivos (UCI) de un hospital universitario terciario. Se utilizó como método un estudio piloto aleatorizado controlado con una muestra de 24 pacientes (51±18,11 años, 16 varones), con 24 a 48 horas de ventilación mecánica (VM), quienes fueron divididos aleatoriamente en dos grupos: grupo de control (n=12), que recibió fisioterapia convencional; y grupo intervención (n=12), que recibió el ejercicio pasivo en cicloergómetro una vez al día durante el período de protocolo de siete días, además de la fisioterapia convencional. El EMC se midió por ecografía. La primera medición ecográfica se realizó entre las primeras 48 horas de VM, y la segunda al final del protocolo. No hubo diferencias significativas en el EMC izquierdo (27,29±5,86 mm vs. 25,95±10,89mm; p=0,558) y derecho (24,96±5,59mm vs 25,9±9,21mm; p=0,682) del grupo de control; y en el EMC izquierdo (27,2±7,38mm vs 29,57±7,89mm; p=0,299) y derecho (26,67±8,16mm vs 28,65±8,04mm; p=0,381) del grupo intervención. En la comparación entre grupos, no hubo cambios significativos en el EMC izquierdo (3,61±1,07 mm; p=0,248) y en el EMC derecho (2,75±0,85 mm, p=0,738). Los resultados de este estudio piloto demostraron que la aplicación precoz del ejercicio pasivo en cicloergómetro no promovió cambios significativos en el espesor de la capa muscular evaluada. Sin embargo, nuestros hallazgos indican que la fisioterapia convencional pudo preservar el EMC de pacientes críticos ingresados en la UCI.


ABSTRACT The objective of this study was to evaluate the effects of early passive cycling exercise on quadriceps femoris thickness (QFT) in critically ill patients admitted in the intensive care unit (ICU) of a tertiary care university hospital. A controlled randomized pilot study was conducted with a sample of 24 patients (51±18.11 years, 16 male), on mechanical ventilation (MV) from 24 to 48 hours, who were randomly divided into two groups: control group (n=12), receiving conventional physical therapy; and an intervention one (n=12), receiving passive cycle ergometer, once a day, throughout seven days of protocol, in addition to conventional physical therapy. The QFT was measured by ultrasonography. The first ultrasonographic measurement was performed within 48 hours after the start of MV, and the second at the end of the protocol. There were no significant differences in QFT of the left (27,29±5,86mm vs 25,95±10,89mm; p=0,558) and right (24,96±5,59mm vs 25,9±9,21mm; p=0,682) in the control group, and in QFT of the left (27,2±7,38mm vs 29,57±7,89mm; p=0,299) and right (26,67±8,16mm vs 28,65±8,04mm; p=0,381) in the intervention group. There were no significant between-groups differences for left QFT (3,61±1,07mm; p=0,248) and right QFT (2,75±0,85mm; p=0,738). The results of this pilot study demonstrate that application of early passive cycle ergometer exercises has not significantly change the muscle layer thickness. However, our findings indicate that conventional physical therapy is able to preserve the quadriceps femoris thickness in critically ill patients admitted in ICU.

ABSTRACT

BACKGROUND: The effects of adding moderate-to-high intensity inspiratory muscle training (IMT) to short-term aerobic and resistance exercise (combined training [CT]), after coronary artery bypass grafting (CABG) are not established. This study aimed to determine the effects of moderate-to-high intensity IMT + CT on exercise capacity, respiratory muscle strength, inspiratory muscle endurance, quality of life (QoL), and laboratory biomarkers in patients after CABG who were participants of a phase II cardiac rehabilitation program. METHODS: Twenty-four patients were randomly assigned to either the IMT + CT group (n = 12), who performed moderate-to-high intensity IMT with CT or the sham-IMT + CT group (n = 12). Patients completed two sessions per week for 12 weeks. Each patient underwent a cardiopulmonary exercise test, six-minute walk test (6MWT), respiratory muscle strength and endurance evaluation, QoL questionnaire, and serum advanced oxidation protein products, ferric reducing antioxidant power [FRAP], nitrate/nitrate, and high-sensitivity C-reactive protein, before and after the 12-week intervention. RESULTS: The IMT + CT group showed significantly greater improvements in peak oxygen uptake (1.3 mL∙kg-1∙min-1; 95% confidence interval [95% CI], 0.5 to 2.2), distance covered during the 6MWT (78.8 m; 95% CI, 28.1 to 129.5), maximal inspiratory pressure (23.0 cmH2O; 95% CI, 9.3 to 36.7), QoL (-15.1 points; 95% CI, -26.9 to -3.3), and FRAP (83.7 µmol/L; 95% CI, 20.2 to 147.1) compared to the sham-IMT + CT group as a result of the intervention. CONCLUSIONS: Short-term moderate-to-high intensity IMT with CT provided additional benefits in exercise capacity, inspiratory muscle strength, QoL, and antioxidant profile in patients after CABG.

ABSTRACT

Objetivo: Analisar as características dos neonatos com Síndro-me do Desconforto Respiratório (SDR), considerando a via de parto, admitidos em uma Unidade de Terapia Intensiva de um hospital universitário da região central do Rio Grande do Sul. Materiais e métodos: Estudo retrospectivo, realizado no período de abril a maio de 2017, através da análise de prontuários de neonatos com idade gestacional acima de 37 semanas, ambos os sexos, internados no ano de 2016 na Unidade de Terapia Intensiva Neonatal (UTIN) do Hospital Universitário de Santa Maria com CID 10 P22 ­ Desconforto (angústia) respiratório(a) do recém-nascido. Resultados: A amostra foi constituída por 40 registros de nascimentos (25 do sexo masculino), divididos em parto vaginal (n=11) e cesárea (n=29), representando 27,5% e 72,5%, respectivamente, das internações totais. A média de idade materna foi de 27±7 anos, com uma média de 7±5 con-sultas pré-natais. Durante o período de internação 65%(n=26) dos 40 neonatos necessitaram de oxigenoterapia. Conclusão:A partir dos resultados obtidos no presente estudo, observamos que a SDR representa 11% das internações ocorridas na UTIN, no ano de 2016. A prevalência, quanto ao tipo de parto, foi de neonatos nascidos de cesariana, sem a presença do trabalho de parto e com idade gestacional de 38 semanas. (AU)


Objective: To analyze the characteristics of newborns with Respiratory Distress Syndrome (RDS), considering the route of delivery, admitted to an Intensive Care Unit of a university hospital in the central region of Rio Grande do Sul, Brazil. Materials and methods: A retrospective study, conducted from April to May 2017, through the analysis of records of neonates with gestational age above 37 weeks, both sexes, hospitalized in 2016 at the Neonatal Intensive Care Unit (NICU) of the Uni-versity Hospital of Santa Maria, with ICD 10 P22 - Respiratory distress syndrome of newborn. Results: The sample consisted of 40 birth records (25 males), divided into vaginal (n = 11) and caesarean (n = 29), representing 27.5% and 72.5%, respective-ly, of total hospitalization. The mean maternal age was 27 ± 7 years, with a mean of 7 ± 5 prenatal consultations. During the hospitalization period, 65% (n = 26) of the 40 neonates required oxygen therapy. Conclusion: Based on the results obtained in the present study, we observed that the RDS represents 11% of the hospitalizations that occurred in the NICU in 2016. The prevalence, in terms of route delivery, was of neonates born caesarean, without the presence of labor and gestational age of 38 weeks. (AU)

ABSTRACT

Justificativa e Objetivos: A DPOC é caracterizada pela limitação progressiva do fluxo aéreo associada a uma resposta inflamatória. O objetivo do estudo foi avaliar a influência e a associação das variáveis respiratórias sobre a capacidade de exercício em portadores de DPOC. Métodos: Estudo transversal avaliou 39 portadores de DPOC para obtenção do volume expiratório forçado no primeiro segundo (VEF1) e a capacidade vital forçada (CVF). A força muscular respiratória (FMR) avaliada em seus componentes de pressão inspiratória máxima (PImax) e pressão expiratória máxima (PEmax). Capacidade de exercício avaliada pelo Teste de Caminhada de Seis Minutos (TC6m) e Incremental Shuttle Walking Test (ISWT). Resultados: O VEF1 (% 39,8±15,3) e CVF (% 60,2±17,1) se encontram reduzidos em relação ao predito classificando-os em estadiamento grau II (21%), III (51%) e IV (28%). A PImax (92,7±14,6 % predito) e PEmax (97,6±19,0 % predito) se encontram dentro dos valores previsto para os sujeitos. Evidenciada correlação moderada entre a distância percorrida no ISWT vs VEF1 (r=0,35; p=0,02) e ISWT vs CVF (r=0,42; p<0,001), TC6m vs VEF1 (r=0,38; p=0,01) e TC6m vs CVF (r=0,52; p<0,001). A FMR se correlacionou diretamente com a distância percorrida no ISWT [PImax (r=0,44; p=0,005); PEmax (r=0,57; p<0,001)] e com TC6m [PImax (r=0,43; p=0,006); PEmax (r=0,59; p<0,001)]. A PEmax e o VEF1 influenciaram 37% do desempenho no TC6m e a PEmax influenciou isoladamente 58% da distância percorrida no ISWT. Conclusão: A força muscular respiratória e os volumes pulmonares reduzidos se associaram e influenciaram diretamente na capacidade de exercício máximo e submáximo de portadores de DPOC.(AU)


Background and Objectives: Chronic Obstructive Pulmonary Disease (COPD) is characterized by progressive airflow limitation associated with an inflammatory response. The aim of the study was to evaluate the influence and the association of respiratory variables on exercise capacity in COPD patients. Methods: A cross-sectional study evaluated 39 COPD patients to obtain forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). Respiratory muscle strength (RMS) was evaluated at its maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) components. Exercise capacity was assessed by Six-Minute Walk Test (6MWT) and Incremental Shuttle Walking Test (ISWT). Results: FEV1 (39.8±15.3%predicted) and FVC (60.2±17.1% predicted) were reduced, which classified them in stages II (21%), III (51%) and IV (28%). MIP (92.7±14.6% predicted) and MEP (97.6±19.0% predicted) were within the expected values. A moderate correlation was observed between the ISWT vs FEV1 (r=0.35;p=0.02) and ISWT vs FVC (r=0.42;p<0.001), 6MWT vs FEV1 (r=0.38;p=0.01) and 6MWT vs FVC (r=0.52;p<0.001). RMS showed a moderate correlation with the ISWT [MIP (r=0.44;p=0.005); MEP (r=0.57;p<0.001)] and 6MWT [MIP (r=0.43;p=0.006); MEP (r=0.59;p<0.001)]. MEP and FEV1 influenced 37% of performance at the 6MWT and MEP alone influenced 58% of distance walked at the ISWT. Conclusion: Reducing both respiratory muscle strength and lung volumes were associated with changes in exercise and they adversely affected the maximum and submaximal exercise capacity in COPD patients.(AU)

El objetivo del estudio fue evaluar la influencia y la asociación de las variables respiratorias sobre la capacidad de ejercicio portadores de EPOC. Métodos: Estudio transversal evaluó 39 portadores de EPOC para obtener el volumen espiratorio forzado en el primer segundo (VEF1) y la capacidad vital forzada (CVF). La fuerza muscular respiratoria (FMR) evaluada en sus componentes de presión inspiratoria máxima (PImax) y presión espiratoria máxima (PEmax). Capacidad de ejercicio evaluada por la Prueba de Caminata de seis minutos (TC6m) e Incremental Shuttle Walking Test (ISWT). Resultados: El VEF1 (% 39,8 ± 15,3) y CVF (% 60,2 ± 17,1) se encuentran reducidos en relación al predicado clasificándolos en estadificación grado II (21%), III (51%) y IV (28%). La PImax (92,7 ± 14,6% predito) y PEmax (97,6 ± 19,0% predito) se encuentran dentro de los valores previstos para los sujetos. Se observó una correlación moderada entre la distancia recorrida en el ISWT vs VEF1 (r = 0,35; p = 0,02) e ISWT vs CVF (r = 0,42; p <0,001), TC6m vs VEF1 (r = 0,38; p = 0,01) y TC6m vs CVF (r = 0,52; p <0,001). La FMR se correlacionó directamente con la distancia recorrida en el ISWT [PImax (r = 0,44; p = 0,005); (P = 0,001) y con TC6m [PImax (r = 0,43; p = 0,006); PEmax (r = 0,59; p <0,001)]. La PEmax y el VEF1 influenciaron el 37% del rendimiento en el TC6m y la PEmax influenció aisladamente el 58% de la distancia recorrida en el ISWT. Conclusión: La fuerza muscular respiratoria y los volúmenes pulmonares reducidos se asociaron e influenciaron directamente en la capacidad de ejercicio máximo y submáximo de portadores de EPOC.(AU)

ABSTRACT

Abstract Introduction: Cardiovascular diseases are a serious public health problem in Brazil. Myocardial revascularization surgery (MRS) as well as cardiac valve replacement and repair are procedures indicated to treat them. Thus, extracorporeal circulation (ECC) is still widely used in these surgeries, in which patients with long ECC times may have greater neurological deficits. Neurological damage resulting from MRS can have devastating consequences such as loss of independence and worsening of quality of life. Objective: To assess the effect of cardiac surgery on a patient's mental state and functional capacity in both the pre- and postoperative periods. Methods: We conducted a cross-sectional study with convenience sampling of subjects undergoing MRS and valve replacement. Participants were administered the Mini-Mental State Exam (MMSE) and the Duke Activity Status Index (DASI) in the pre- and postoperative periods, as well as before their hospital discharge. Results: This study assessed nine patients (eight males) aged 62.4 ± 6.3 years with a BMI of 29.5 ± 2.3 kg/m2. There was a significant decrease in DASI scores and VO2 from preoperative to postoperative status (p = 0.003 and p = 0.003, respectively). Conclusion: This study revealed a loss of cognitive and exercise capacity after cardiac surgery. A larger sample however is needed to consolidate these findings.


Resumo Introdução: As doenças cardiovasculares são um grave problema de saúde pública no Brasil, sendo as cirurgias de revascularização do miocárdio (CRM) e reparações ou trocas valvares, indicadas para tratamento destas doenças. Assim, a circulação extracorpórea (CEC) ainda é muito utilizada nestas cirurgias, onde pacientes com tempo elevado de CEC podem apresentaram maiores déficits neurológicos. Os danos neurológicos decorrentes da CRM podem ter consequências devastadoras como perda de independência e piora na qualidade de vida. Objetivo: Avaliar o efeito da cirurgia cardíaca sobre o estado mental e capacidade funcional de pacientes cardiopatas nos períodos pré e pós-operatório. Métodos: Estudo transversal, com amostra de conveniência, onde os sujeitos foram submetidos à CRM e troca valvar. Foram aplicados os questionários Mini-Mental State Exam (MMSE) e o Duke Activity Status Index (DASI), no período pré-operatório e antes da alta hospitalar. Resultados: Foram avaliados nove pacientes (oito homens) com idade 62,4 ± 6,3 anos e IMC 29,5 ± 2,3 Kg/m2. Observou-se uma queda significativa no DASI e no VO2 no período pós em relação ao pré-operatório (p = 0,003 e p = 0,003, respectivamente). Conclusão: No presente estudo constatou-se uma perda da capacidade cognitiva e de exercício após a cirurgia cardíaca. No entanto, um aumento do tamanho amostral faz-se necessário para consolidação dos resultados.

ABSTRACT

Abstract Background The pathophysiology of chronic obstructive pulmonary disease (COPD) is complex and understanding of it has been changing in recent years, with regard to its multisystemic manifestations, especially peripheral dysfunction and its influence on intolerance to exercise. Objectives To evaluate the relationship between peripheral arterial occlusive disease (PAOD) and peripheral muscle strength and exercise capacity in COPD patients. Methods We conducted a cross-sectional study of 35 patients with COPD who were evaluated with the Ankle-Brachial Index, handgrip strength test, 1 repetition maximum (1RM) of knee extensors and flexors, and distance covered in the incremental shuttle walking test (dISWT). Results COPD patients with coexisting PAOD had lower dominant handgrip strength test results (33.00 vs. 26.66 kgf, p = 0.02) and worse performance in the dISWT (297.32 vs. 219.41 m, p = 0.02) when compared to the COPD patients without PAOD. Strong correlations were found between the result of the handgrip strength test and both the dISWT (r = 0.78; p < 0.001) and the 1RM/knee extension (r = 0.71; p = 0.03); and also between the dISWT and both the 1RM/knee extension (r = 0.72; p = 0.02) and the 1RM/knee flexion (r = 0.92; p < 0.001). The linear regression model showed that the dISWT variable alone explains 15.3% of the Ankle-Brachial Index result (p = 0.01). Conclusion COPD patients with PAOD exhibit reduced muscle strength and lower exercise capacity than COPD patients without PAOD.


Resumo Contexto A doença pulmonar obstrutiva crônica (DPOC) apresenta uma complexa fisiopatologia e sua compreensão vem se modificando nos últimos anos, com atenção para as manifestações multissistêmicas, em especial a disfunção periférica e sua influência na intolerância ao exercício físico. Objetivo Avaliar o impacto da doença arterial periférica obstrutiva (DAOP) na força muscular periférica e na capacidade de exercício dos portadores de DPOC. Métodos Estudo transversal realizado com 35 portadores de DPOC, que foram avaliados pelo índice tornozelo-braquial, teste de força de preensão palmar (FPP), uma repetição máxima (1RM) de extensores e flexores de joelho, e a distância no incremental shuttle walking test (dISWT). Resultados Portadores de DPOC com DAP coexistente apresentaram menor FPP da mão dominante (33,00 versus 26,66 kgf, p = 0,02) e pior desempenho no dISWT (297,32 versus 219,41 m, p = 0,02) quando comparados aos portadores de DPOC sem DAP. Fortes correlações foram encontradas entre a medida da FPP e a dISWT (r = 0,78; p < 0,001) e a 1RM/extensão de joelho (r = 0,71; p = 0,03); entre a dISWT e a 1RM/extensão de joelho (r = 0,72; p = 0,02) e a 1RM/flexão de joelho (r = 0,92; p < 0,001). O modelo de regressão linear identificou que a variável dISWT explica isoladamente 15,3% do resultado do índice tornozelo braquial (p = 0,01). Conclusão Portadores de DPOC com DAOP coexistente apresentam maior perda da força muscular periférica e pior desempenho da capacidade de exercício quando comparados aos portadores de DPOC sem DAOP.

ABSTRACT

Abstract Introduction: In the Chronic Obstructive Pulmonary Disease (COPD) both pulmonary and systemic condition increase dyspnea, intolerance to exercise and inactivity. Objective: To evaluate possible association between Hand Grip Strength (HGS) and the distance covered in the Six-Minute Walk Test (6MWT) in patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: A cross-sectional study that evaluated 34 patients with COPD from moderate to very severe stages. The HGS test was performed with a manual hydraulic dynamometer (Jamar®, California, USA) with three bilateral measures, allowing 60-seconds rest time in-between measurements. Afterwards, the patients were submitted to the 6MWT along a 30-meters level corridor following the rules of the American Thoracic Society. Results: Average age 62.7±7.2 years old, body mass index 26.7±6.9 Kg/m². The value of the HGS in the dominant hand was 28.0±8.7 Kgf and in the non-dominant hand was 26.7±7.7 Kgf (99.2% of the predicted value and 106.3% of the predicted value, respectively). The subjects covered in average 421.0±110.4 meters in the 6MWT and there has been detected direct and significant correlation between the distance covered and the HGS of the dominant hand (r=0,430; p=0,011) and non-dominant (r=0,502; p=0,002). The patients with COPD that presented lower HGS also covered less distance in the 6MWT. Conclusion: The hand grip strength was directly associated with the functional capacity assessed through the distance covered in the Six-Minute Walk Test in the evaluated trial.


Resumo Introdução: Nos portadores de Doença Pulmonar Obstrutiva Crônica (DPOC), a disfunção pulmonar, as manifestações sistêmicas e o aumento da dispneia podem conduzir à piora progressiva do condicionamento físico, à inatividade e intolerância ao exercício físico. Objetivo: avaliar possível associação entre a força de preensão palmar (FPP) e a distância percorrida no Teste de Caminhada de Seis Minutos (TC6M) em portadores de DPOC. Métodos: Estudo transversal que avaliou 34 portadores de DPOC com estadiamento entre moderado a muito severo. A FPP foi realizada com dinamômetro hidráulico manual (Jamar®, Califórnia, EUA) com três medidas bilateralmente, respeitando um tempo de descanso de 60 segundos entre as medidas. Posteriormente, os pacientes foram submetidos ao TC6M em um corredor plano de 30 metros, seguindo as normas da American Thoracic Society. Resultados: Média de idade de 62,7±7,2 anos, índice de massa corporal 26,7±6,9 Kg/m². O valor da FPP na mão dominante foi 28,0±8,7 Kgf e da mão não dominante foi 26,7±7,7 Kgf (99,2% do predito e 106,3% do predito, respectivamente). Os sujeitos percorreram em média 421,0±110,4 metros no TC6M tendo sido detectada correlação direta e significativa entre a distância percorrida e a FPP da mão dominante (r=0,430; p=0,011) e não-dominante (r=0,502; p=0,002). Os portadores de DPOC que apresentaram menor FPP apresentaram menor distância no TC6M. Conclusão: A força de preensão palmar esteve diretamente associada à capacidade funcional avaliada através da distância percorrida no Teste de Caminhada de Seis Minutos na amostra avaliada.

ABSTRACT

O objetivo deste estudo foi avaliar os efeitos da ventilação não invasiva (VNI) por pressão positiva contínua nas vias aéreas (Continuos Positive Airway Pressure - CPAP) e por pressão positiva em dois níveis (Bilevel Positive Airway Pressure - BiPAP) sobre a demanda miocárdica no pós-operatório (PO) de revascularização miocárdica (RVM) e troca valvar. Analisa-se um estudo cross-over que submeteu pacientes de ambos os sexos (50 a 80 anos) à CPAP (9 cmH20) e BiPAP (IPAP de 12 cmH2O e EPAP de 6 cmH2O) por 20 minutos com posterior avaliação do duplo produto (DP). Foi feito o registro da frequência cardíaca (FC) e da pressão arterial sistólica (PAS) no 1º, 10º e 20º minuto da VNI comparado através do ANOVA two-way e seguido pelo post hoc de Bonferroni. O teste t Student comparou a diferença entre os grupos (p<0,05). A amostra foi composta por 12 sujeitos com idade de 66,2±12,5 anos e índice de massa corporal de 24,3±5,0 Kg/m2. Não foi evidenciada diferença no DP após aplicação do CPAP ou BiPAP (p= 0,829) nem na FC e PAS. O VNI por CPAP e BiPAP não teve repercussão significativa sobre as variáveis hemodinâmicas avaliadas, o que torna a VNI um recurso seguro para aplicação no PO de cirurgias cardíacas.


This study aims to assess the effects of non-invasive ventilation (NIV) by continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BIPAP) on patients' myocardial demand in the postoperative (PO) of myocardial revascularization (RVM) and valve replacement. A crossover study involving patients of both genders (50-80 years) with CPAP (9 cmH20) and BiPAP (IPAP of 12 cmH2O and EPAP of 6 cmH2O) during 20 minutes with posterior assessment of the double product (DP). It was made the record of heart rate (HR) and systolic pressure (SP) at the 1st, 10th and 20th minute of NIV and comparing them with use of two-way ANOVA, followed by Bonferroni post hoc. The Student's t-test compared difference between groups (p <0.05). The sample had 12 subjects, with age 66,2±12,5 years and body mass index of 24,3±5,0 Kg/m2. There was no difference in DP after application of CPAP or BiPAP (p= 0.829), neither in HR nor SBP. The NIV by CPAP and BiPAP had no significant repercussion on the hemodynamic variables assessed, which makes NIV a safe resource for application in the PO of cardiac surgeries.

ABSTRACT

Este artigo visa analisar a força muscular respiratória (FMR) de puérperas primíparas de parto normal e nulíparas. Trata-se de estudo do tipo caso-controle que avaliou 59 mulheres alocadas no grupo puérperas (GP) (primigestas, n=29) e no grupo controle (GC) (nuligestas, n=30). Foram avaliadas características antropométricas e FMR (PImax e PEmax) por meio da manovacuometria digital. O teste t Student comparou dados antropométricos e da FMR entre os grupos. A correlação de Pearson (p<0,05) avaliou a associação entre idade, índice de massa corporal (IMC) e FMR. Houve diferença significante na PImax (p<0,001) e na PEmax (p<0,001) entre GC e GP. A média da PImax (%predito) no GP e GC foi 39,1 ± 16,2 cmH2O e 82,3 ± 23,9 cmH2O e a da PEmax (%predito) foi 34,7 ± 14,6 cmH2O e 80,4 ± 18,4 cmH2O, respectivamente. Houve correlação negativa entre idade e PEmax no GP (r= -0,378; p= 0,043). Evidenciou-se, sem distinção entre grupos, uma correlação negativa de pequena a moderada entre IMC e PImax (r=-0,380; p=0,003) e PEmax (r= -0,525; p<0,001). Foi evidenciada uma FMR menor que pode estar relacionada às alterações decorrentes da gestação na configuração da parede torácica.


This paper aims to analyze the respiratory muscle strength (RMS) of primiparous women of normal delivery and nulliparous. It is a case-control study that assess 59 women allocated to the Puerperal Group (PG) (primiparous, n= 29) and Control Group (CG) (niligestas, n= 30). Anthropometric and RMS characteristics were assessed (MIP and MEP) through digital manovacuometer. The Student's t-test compared anthropometric and RMS data between groups. The Pearson correlation (p<0.05) assessed the association between age, body mass index (BMI) and RMS. There was a significant difference in the MIP (p <0.001) and the MEP (p <0.001) between CG and PG.. The average MIP (predicted%) in PG and CG was 39.1 ± 16.2 cmH2O and 82.3±23.9 cmH2O and the MEP (% predicted) was 34.7±14.6 cmH2O and 80,4±18.4 cmH2O, respectively. There was a negative correlation between age and MEP in PG (r = -0.378; p = 0.043). It was evidenced, without distinction between groups, a small to moderate negative correlation between BMI and MIP (r = -0.380, p = 0.003) and MEP (r = -0.525, p<0.001). A lower FMR was evidenced, which may be related to changes in the chest wall configuration due to gestation.

ABSTRACT

OBJETIVOS: Avaliar a potencial relação entre classe funcional segundo a New York Heart Association e a fração de ejeção do ventrículo esquerdo em pacientes com doença coronariana candidatos à reabilitação cardíaca. MÉTODOS: Foi realizado um estudo transversal retrospectivo, por meio da análise de prontuários de pacientes com doença coronariana candidatos ao Programa de Reabilitação Cardíaca do Hospital Universitário de Santa Maria, Rio Grande do Sul. Foram incluídos pacientes de ambos os sexos, com idade entre 50 e 65 anos, sendo excluídos aqueles com insuficiência renal crônica, anemia, ecocardiograma com baixa qualidade de imagem, pacientes com ritmo não sinusal e indivíduos cujos prontuários não apresentavam informações suficientes. A coleta dos dados ocorreu no período de agosto de 2015 a março de 2016, tendo sido extraídas dos prontuários as informações que compuseram as variáveis de interesse, tais como: dados clínicos e demográficos (sexo, idade, comorbidades, diagnóstico clínico, tratamento cirúrgico e medicamentoso), valores da fração de ejeção do ventrículo esquerdo coletados através de ecocardiografia (Doppler convencional e Doppler tecidual) e a classe funcional a partir do teste ergométrico. A análise estatística foi realizada mediante a aplicação do teste de Kruskal-Wallis seguido do post hoc de Dunn. O nível de significância estatística adotado foi de p<0,05. RESULTADOS: Foram avaliados consecutivamente 131 prontuários, sendo que 102 preencheram os critérios de inclusão. A média de idade da amostra foi de 59,23±7,95 anos e 70 (68,63%) pacientes eram do sexo masculino. Ocorreu predomínio da classe funcional I. Observouse relação inversa entre classe funcional e fração de ejeção do ventrículo esquerdo: quanto mais avançada a classe funcional, maior foi o comprometimento do desempenho cardíaco (p=0,036). CONCLUSÕES: Nesta amostra de pacientes com doença coronariana, ingressantes em um programa de reabilitação cardíaca, houve relação inversa entre fração de ejeção do ventrículo esquerdo e progressão da classe funcional. Este achado fornece informações sobre as limitações impostas pela doença na capacidade de exercício e na função cardíaca do paciente e pode auxiliar na elaboração de um programa de treinamento físico.


AIMS: To assess the potential relation between the New York Heart Association functional class and left ventricular ejection fraction in coronary heart disease patients who were candidates for cardiac rehabilitation. METHODS: This is a retrospective cross-sectional study based on the analysis of medical records of coronary heart disease patients who were candidates for the Cardiac Rehabilitation Program of Hospital Universitário de Santa Maria, state of Rio Grande do Sul, Brazil. Both male and female patients aged 50 to 65 were included, whereas patients with chronic renal failure, anemia, poor echocardiographic image quality, nonsinus rhythm, and also those individuals whose medical records lacked sufficient information were excluded. Data were collected from August 2015 to March 2016, and the information that made up the variables of interest was extracted from the medical records, such as: clinical and demographic data (sex, age, comorbidities, clinical diagnosis, surgical and drug treatment), left ventricular ejection fraction values obtained by echocardiography (conventional and tissue Doppler echocardiography), and functional class from the ergometric test. Statistical analysis was performed using Kruskal-Wallis test followed by Dunn's post-hoc test. The significance level was set at p<0.05. RESULTS: A total of 131 medical records were consecutively evaluated, of which 102 met the inclusion criteria. Mean age was 59.23±7.95 years and 70 (68.63%) patients were male, with a predominance of functional class I. There was an inverse relation between functional class and ejection fraction: the more advanced the functional class, the more compromised the cardiac performance (p=0.036). CONCLUSIONS: In this sample of patients with coronary heart disease who were candidates for cardiac rehabilitation, there was an inverse relation between left ventricular ejection fraction and functional class. This finding provides information about the limitations imposed by the disease on patient's exercise capacity and heart function and can contribute to the development of a physical training program.

ABSTRACT

Objective: To evaluate the effects that passive cycling exercise, in combination with conventional physical therapy, have on peripheral muscle strength, duration of mechanical ventilation, and length of hospital stay in critically ill patients admitted to the ICU of a tertiary care university hospital. Methods: This was a randomized clinical trial involving 38 patients (≥ 18 years of age) on mechanical ventilation who were randomly divided into two groups: control (n = 16), receiving conventional physical therapy; and intervention (n = 22), receiving conventional physical therapy and engaging in passive cycling exercise five days per week. The mean age of the patients was 46.42 ± 16.25 years, and 23 were male. The outcomes studied were peripheral muscle strength, as measured by the Medical Research Council scale, duration of mechanical ventilation, and length of hospital stay. Results: There was a significant increase in peripheral muscle strength (baseline vs. final) in both groups (control: 40.81 ± 7.68 vs. 45.00 ± 6.89; and intervention: 38.73 ± 11.11 vs. 47.18 ± 8.75; p < 0.001 for both). However, the range of increase in strength was higher in the intervention group than in the control group (8.45 ± 5.20 vs. 4.18 ± 2.63; p = 0.005). There were no significant differences between the groups in terms of duration of mechanical ventilation or length of hospital stay. Conclusions: The results suggest that the performance of continuous passive mobilization on a cyclical basis helps to recover peripheral muscle strength in ICU patients.

ABSTRACT

ABSTRACT Objective: To evaluate the effects that passive cycling exercise, in combination with conventional physical therapy, have on peripheral muscle strength, duration of mechanical ventilation, and length of hospital stay in critically ill patients admitted to the ICU of a tertiary care university hospital. Methods: This was a randomized clinical trial involving 38 patients (≥ 18 years of age) on mechanical ventilation who were randomly divided into two groups: control (n = 16), receiving conventional physical therapy; and intervention (n = 22), receiving conventional physical therapy and engaging in passive cycling exercise five days per week. The mean age of the patients was 46.42 ± 16.25 years, and 23 were male. The outcomes studied were peripheral muscle strength, as measured by the Medical Research Council scale, duration of mechanical ventilation, and length of hospital stay. Results: There was a significant increase in peripheral muscle strength (baseline vs. final) in both groups (control: 40.81 ± 7.68 vs. 45.00 ± 6.89; and intervention: 38.73 ± 11.11 vs. 47.18 ± 8.75; p < 0.001 for both). However, the range of increase in strength was higher in the intervention group than in the control group (8.45 ± 5.20 vs. 4.18 ± 2.63; p = 0.005). There were no significant differences between the groups in terms of duration of mechanical ventilation or length of hospital stay. Conclusions: The results suggest that the performance of continuous passive mobilization on a cyclical basis helps to recover peripheral muscle strength in ICU patients.

RESUMO Objetivo: Avaliar os efeitos da realização de exercícios passivos com um cicloergômetro, associada à fisioterapia convencional, na força muscular periférica, no tempo de ventilação mecânica e no tempo de internação hospitalar em pacientes críticos internados em UTI de um hospital universitário terciário. Métodos: Ensaio clínico randomizado envolvendo 38 pacientes (idade > 18 anos) em ventilação mecânica e divididos aleatoriamente em grupo controle (n = 16), que realizou fisioterapia convencional, e grupo intervenção (n = 22) submetidos a fisioterapia convencional e exercícios passivos em cicloergômetro cinco vezes por semana. A média de idade dos pacientes foi de 46,42 ± 16,25 anos, e 23 eram homens. Os desfechos analisados foram força muscular periférica, mensurada pela escala Medical Research Council, tempo de ventilação mecânica e tempo de internação hospitalar. Resultados: Houve um aumento significativo da força muscular periférica (basal vs. final) tanto no grupo controle (40,81 ± 7,68 vs. 45,00 ± 6,89; p < 0,001) quanto no grupo intervenção (38,73 ± 11,11 vs. 47,18 ± 8,75; p < 0,001). Entretanto, a variação do aumento da força foi maior no grupo intervenção que no controle (8,45 ± 5,20 vs. 4,18 ± 2,63; p = 0,005). Não foram observadas diferenças significativas entre os grupos quanto ao tempo de ventilação mecânica e tempo de internação hospitalar. Conclusões: Os resultados sugerem que a realização de mobilização passiva contínua de forma cíclica auxilia na recuperação da força muscular periférica de pacientes internados em UTI.

ABSTRACT

BACKGROUND: The pathophysiology of chronic obstructive pulmonary disease (COPD) is complex and understanding of it has been changing in recent years, with regard to its multisystemic manifestations, especially peripheral dysfunction and its influence on intolerance to exercise. OBJECTIVES: To evaluate the relationship between peripheral arterial occlusive disease (PAOD) and peripheral muscle strength and exercise capacity in COPD patients. METHODS: We conducted a cross-sectional study of 35 patients with COPD who were evaluated with the Ankle-Brachial Index, handgrip strength test, 1 repetition maximum (1RM) of knee extensors and flexors, and distance covered in the incremental shuttle walking test (dISWT). RESULTS: COPD patients with coexisting PAOD had lower dominant handgrip strength test results (33.00 vs. 26.66 kgf, p = 0.02) and worse performance in the dISWT (297.32 vs. 219.41 m, p = 0.02) when compared to the COPD patients without PAOD. Strong correlations were found between the result of the handgrip strength test and both the dISWT (r = 0.78; p < 0.001) and the 1RM/knee extension (r = 0.71; p = 0.03); and also between the dISWT and both the 1RM/knee extension (r = 0.72; p = 0.02) and the 1RM/knee flexion (r = 0.92; p < 0.001). The linear regression model showed that the dISWT variable alone explains 15.3% of the Ankle-Brachial Index result (p = 0.01). CONCLUSION: COPD patients with PAOD exhibit reduced muscle strength and lower exercise capacity than COPD patients without PAOD.


CONTEXTO: A doença pulmonar obstrutiva crônica (DPOC) apresenta uma complexa fisiopatologia e sua compreensão vem se modificando nos últimos anos, com atenção para as manifestações multissistêmicas, em especial a disfunção periférica e sua influência na intolerância ao exercício físico. OBJETIVO: Avaliar o impacto da doença arterial periférica obstrutiva (DAOP) na força muscular periférica e na capacidade de exercício dos portadores de DPOC. MÉTODOS: Estudo transversal realizado com 35 portadores de DPOC, que foram avaliados pelo índice tornozelo-braquial, teste de força de preensão palmar (FPP), uma repetição máxima (1RM) de extensores e flexores de joelho, e a distância no incremental shuttle walking test (dISWT). RESULTADOS: Portadores de DPOC com DAP coexistente apresentaram menor FPP da mão dominante (33,00 versus 26,66 kgf, p = 0,02) e pior desempenho no dISWT (297,32 versus 219,41 m, p = 0,02) quando comparados aos portadores de DPOC sem DAP. Fortes correlações foram encontradas entre a medida da FPP e a dISWT (r = 0,78; p < 0,001) e a 1RM/extensão de joelho (r = 0,71; p = 0,03); entre a dISWT e a 1RM/extensão de joelho (r = 0,72; p = 0,02) e a 1RM/flexão de joelho (r = 0,92; p < 0,001). O modelo de regressão linear identificou que a variável dISWT explica isoladamente 15,3% do resultado do índice tornozelo braquial (p = 0,01). CONCLUSÃO: Portadores de DPOC com DAOP coexistente apresentam maior perda da força muscular periférica e pior desempenho da capacidade de exercício quando comparados aos portadores de DPOC sem DAOP.

ABSTRACT

BACKGROUND: We hypothesized that the use of oxygen supplementation during aerobic exercise induces less DNA damage than exercise alone. The aim of this study is to assess the level of DNA damage induced by physical exercise with and without oxygen supplementation in chronic obstructive pulmonary diseases (COPD) patients. METHODS: Peripheral blood was collected before and after aerobic exercise in two conditions: (I) aerobic exercise without oxygen supplementation (AE group) and (II) with oxygen supplementation (AE-O2 group). Lymphocytes were collected to perform the alkaline version of the Comet Assay. To assess the susceptibility to exogenous DNA damage, the lymphocytes were treated with methyl methanesulphonate (MMS) for 1-h or 3-h. After 3-h treatment, the percentage of residual damage was calculated assuming the value of 1-h MMS treatment as 100%. RESULTS: AE group showed lower induced damage (1 h of MMS treatment) and consequently less DNA repair compared to AE-O2 group. AE-O2 group showed an increase in the induced DNA damage (1 h of MMS treatment) and an increased DNA repair capacity. Within the AE-O2 group, in the post-exercise situation the induced DNA damage after 1 h of MMS treatment was higher (p = 0.01) than in the pre-exercise. CONCLUSION: COPD patients who performed physical exercise associated with oxygen supplementation had a better response to DNA damage induced by MMS and a better DNA repair when compared to the condition of physical exercise without oxygen supplementation.
