RESUMEN
ABSTRACT Objective: To evaluate the impact of COVID-19 social distancing recommendations on nutritional status, pulmonary function, and morbidity in patients with cystic fibrosis (CF). Methods: A retrospective cohort study including patients older than six years with a diagnosis of CF was performed. Demographic and clinical data, anthropometric measurements, pulmonary function, days of antibiotic use, and length of hospital stay were recorded. Variables were recorded at three time points relative to the baseline for implementation of social distancing measures: T-1 (14 months before implementation), T0 (baseline), and T1 (14 months after implementation). Delta (Δ) was calculated for each period: Δ1 (pre-pandemic T0-T-1) and Δ2 (pandemic T1-T0). Results: The study included 25 patients, with a mean age of 11.7±4.3 years. The mean forced expiratory volume in the first second (FEV1) was 85.6±23.6%, and body mass index (BMI) was 17.5±3.0 kg/m2. When comparing the two periods (Δ1 and Δ2), there was a significant increase in the FEV1/forced vital capacity (FVC) ratio (p=0.013) and in the forced expiratory flow between 25 and 75% of vital capacity (FEF25-75%) (p=0.037) in the pandemic period. There was also a significant reduction (p=0.005) in the use of antibiotics in the pandemic period compared with the pre-pandemic period. The Δ1 and Δ2 values did not differ significantly for BMI, FEV1, or length of hospital stay. Conclusions: COVID-19 social distancing recommendations had a positive impact (decrease) on morbidity (use of antibiotics) and small airway obstruction (FEF25-75%) in patients with CF.
RESUMO Objetivo: Avaliar o impacto das recomendações de medidas de distanciamento social por COVID-19 sobre estado nutricional, função pulmonar e morbidade em pacientes com fibrose cística (FC). Métodos: Estudo de coorte, retrospectivo, que incluiu pacientes com diagnóstico de FC e idade superior a seis anos. Foram registrados os dados demográficos, antropométricos, clínicos, de função pulmonar e o total de dias de uso de antibiótico e de hospitalizações. As variáveis foram registradas em três momentos relativos ao início das recomendações de distanciamento social: T-1 (14 meses antes), T0 (início das recomendações) e T1 (14 meses depois). Foram calculados deltas (Δ) para cada um dos períodos: Δ1 (pré-pandemia T0-T-1) e Δ2 (pandemia T1-T0). Resultados: Vinte e cinco pacientes, com média de idade de 11,7±4,3 anos, sendo 76% homozigotos para Δf508 e 28% colonizados por Pseudomonas aeruginosa, foram incluídos. A média do volume expiratório forçado no primeiro segundo (VEF1) foi de 85,6±23,6 (% do previsto) e o índice de massa corporal (IMC) foi de 17,5±3,0 kg/m2. Ao compararmos os períodos (Δ1 e Δ2), houve aumento significativo do VEF1/CVF (p=0,013) e do FEF25-75% (p=0,037) no período das recomendações de distanciamento. Também se observou redução significativa (p=0,005) do uso de antibióticos no período da pandemia em comparação ao período anterior a ela. Não houve diferenças significativas nos deltas para o IMC, VEF1 e dias de hospitalização. Conclusões: As recomendações de distanciamento social por COVID-19 tiveram impacto positivo (redução) sobre a morbidade (uso de antibióticos) e a obstrução de vias aéreas de menor calibre (FEF25-75%) em pacientes com FC.

OBJECTIVE: To evaluate the exercise capacity of children and adolescents with severe therapy resistant asthma (STRA) aiming to identify its main determinants. METHODS: Cross-sectional study including individuals aged 6-18 years with a diagnosis of STRA. Clinical (age and gender), anthropometric (weight, height and body mass index) and disease control data were collected. Lung function (spirometry), cardiopulmonary exercise testing (CPET) and exercise-induced bronchoconstriction (EIB) test were performed. RESULTS: Twenty-four patients aged 11.5 ± 2.6 years were included. The mean forced expiratory volume in one second (FEV1) was 91.3 ± 9.2%. EIB occurred in 54.2% of patients. In CPET, the peak oxygen uptake (VO2peak) was 34.1 ± 7.8 mL kg-1 min-1. A significant correlation between ventilatory reserve and FEV1 (r = 0.57; p = 0.003) was found. Similarly, there was a significant correlation between CPET and percent of FEV1 fall in the EIB test for both VE/VO2 (r = 0.47; p = 0.02) and VE/VCO2 (r = 0.46; p = 0.02). Patients with FEV1<80% had lower ventilatory reserve (p = 0.009). In addition, resting heart rate correlated with VO2peak (r=-0.40; p = 0.04), VE/VO2 (r = 0.46; p = 0.02) and VE/VCO2 (r = 0.48; p = 0.01). CONCLUSIONS: Exercise capacity is impaired in approximately 30% of children and adolescents with STRA. The results indicate that different aspects of aerobic fitness are influenced by distinct determinants, including lung function and EIB.

INTRODUCTION: The aim of the study was to evaluate the diagnostic performance of the item concerning physical activity of the Global Initiative for Asthma (GINA) asthma control questionnaire for detection of exercise-induced bronchoconstriction (EIB) in children and adolescents. MATERIAL AND METHODS: We divided participants (aged 6-18 years) with a diagnosis of asthma into two groups according to the GINA severity classification: mild/moderate asthma (MMA) and severe therapy-resistant asthma (STRA). We collected anthropometric, clinical and functional data (spirometry) and performed an EIB test. We used item 4 of the GINA questionnaire regarding exercise-induced symptoms to assess the diagnostic power of this instrument. RESULTS: We included 40 patients (17 with MMA and 23 with STRA) with a mean age of 11.3 years and a mean FEV1z-score of -0.33, of who 13 (32.5%) were classified as having uncontrolled asthma. Of the patients with uncontrolled asthma, 7 (53.8%) exhibited a decrease in the FEV1 after the EIB test. We found a higher frequency of EIB in participants with FEV1 z-score values of less than -1.0 compared to those with a z-score of -1.0 or greater (P = .05). There were no significant differences in the frequency of EIB based on disease severity and control. We also found no association of item 4 (GINA) with EIB. The area under the ROC curve demonstrated that the discriminative power of the GINA questionnaire for the detection of EIB is inadequate (P = .41), with sensitivity of 42.1% and specificity of 57.1%. CONCLUSIONS: The item concerning physical activity in the GINA questionnaire has insufficient diagnostic power to detect EIB in children and adolescents with asthma.

Introducción: El objetivo del estudio fue evaluar el rendimiento diagnóstico de la pregunta relacionada con la actividad física del cuestionario de control del asma de la Global Initiative for Asthma (GINA) para la detección de la broncoconstricción inducida por el ejercicio (BIE) en niños y adolescentes.Materiales y métodos: Se dividió a pacientes (de seis a 18 años de edad) con diagnóstico de asma en dos grupos de acuerdo con la clasificación de gravedad según el cuestionario GINA: asma leve/moderada (ALM) y asma grave refractaria (AGR). Se recogieron datos antropométricos, clínicos y funcionales (espirometría) y se realizó prueba de broncoprovocación con esfuerzo. Se utilizó la cuarta pregunta del cuestionario GINA, concerniente a los síntomas asociados con el esfuerzo físico, para evaluar el rendimiento diagnóstico de este instrumento.Resultados: Se incluyeron a 40 pacientes (17 con ALM y 23 con AGR) con una edad media de 11,3 años y un z-score medio de FEV1 de -0,33, de los que 13 (32,5%) se clasificaron como casos de asma no controlada. De los pacientes con enfermedad no controlada, siete (53,8%) mostraron caídas en el FEV1 tras la prueba de esfuerzo. Se observó una mayor frecuencia de BIE en sujetos con z-score de FEV1 < -1,0 en comparación con aquellos con un z-score ≥ -1,0 (p = 0,05). No hubo diferencias significativas en la frecuencia de BIE con base en la gravedad o el control de la enfermedad. Tampoco se observó asociación entre la pregunta cuatro (GINA) y la BIE. El área bajo la curva de características operativas del receptor (receiver operating characteristic, ROC) evidenció que el poder discriminatorio del cuestionario GINA resulta insuficiente para detectar la BIE (p = 0,41), con una sensibilidad del 42,1% y una especificidad del 57,1%.Conclusiones: La pregunta concerniente al ejercicio físico en el cuestionario GINA carece del poder diagnóstico necesario para detectar la BIE en niños y adolescentes asmáticos.

BACKGROUND: Lower exercise tolerance is an important component of asthma and the possible effects of non-invasive ventilation on exercise capacity in individuals with severe therapy-resistant asthma (STRA) are unknown. This study aimed to evaluate the immediate effect of continuous positive airway pressure (CPAP) on exercise tolerance in children with STRA. METHODS: We performed a controlled, randomized, crossover clinical trial including subjects aged 6 to 18 years old diagnosed with STRA. Clinical, anthropometric and lung function data were collected. The participants in the intervention group (IG) used CPAP (PEEP 10cmH2O and FiO2 0.21) for a period of 40 min. Subjects in the control group (CG) used CPAP with minimum PEEP at 1 cmH20 also for 40 min. Afterwards, subjects from both groups underwent cardiopulmonary exercise testing (CPET). After a 15-day washout period, on a subsequent visit, subjects participated in the opposite group to the initial one. RESULTS: Thirteen subjects with a mean age of 12.30 ± 1.7 years were included. The variables of peak expiratory flow (PEF) and forced expiratory volume in the first second (FEV1) before using CPAP and after performing CPET did not show significant differences. Regarding CPET results, there was no significant difference (P = 0.59) between groups at peak exercise for oxygen consumption-VO2 (CG: 33.4 ± 6.3 and IG: 34.5 ± 5.9, mL kg-1 min-1). However, the IG (12.4 ± 2.1) presented a total test time (min) significantly (P = 0.01) longer than the CG (11.5 ± 1.3). CONCLUSION: The results suggest that the use of CPAP before physical exercise increases exercise duration in children and adolescents with STRA.

AIMS: Individuals with cystic fibrosis (CF) may develop muscle abnormalities, although little is known on its clinical and functional impact. This study aimed to evaluate the association of peripheral muscle strength with aerobic fitness, habitual physical activity, lung function and the use of antibiotics (ATB) in patients with CF. METHODS: A cross-sectional study where individuals aged ≥6 years underwent peripheral muscle strength evaluation (biceps, quadriceps and hamstrings) and performed a cardiopulmonary exercise test. Demographic, anthropometric, genetic, lung function and total days of ATB use within 1 year of tests were also collected. RESULTS: Correlation was found for biceps (r = .45; P = .002) strength with the peak oxygen consumption (VO2 peak). Muscle strength (biceps and quadriceps) also correlated with the ventilatory equivalent for oxygen consumption (VE /VO2 ) at anaerobic threshold (AT) and with the ventilatory equivalent for carbon dioxide production (VE /VCO2 ) both at AT and peak exercise. Negative correlations were found for quadriceps (r = -.39) and hamstrings (r = -.42) with the total days of ATB use in the following year. Patients needing to use ATB presented lower biceps strength (P = .05) and individuals with VO2 peak lower than 37 mL·kg-1 ·min-1 presented lower muscle strength for both biceps (P = .01) and quadriceps (P = .02). CONCLUSIONS: The results have shown that peripheral muscle strength is associated with aerobic fitness and the use of antibiotics in patients with CF.

ABSTRACT Objective: To identify the effects of exercise programs during hospitalization on children and adolescents with cancer. Data source: This is a systematic review, carried out in PubMed/ Medical Literature Analysis and Retrieval System Online (MEDLINE), Latin American and Caribbean Health Sciences Literature (LILACS), Scientific Electronic Library Online (SciELO), Latin American and Caribbean Center on Health Sciences Information (BIREME), and Physiotherapy Evidence Database (PEDro). We selected studies that included children and adolescents diagnosed with cancer (solid or hematologic) and submitted to exercise protocols during hospitalization. Studies involving patients with other pathologies or with a medical contraindication for exercise were excluded. We used the following search strategy: Neoplasm OR Leukemia OR Cancer OR Tumor OR Medical Oncology AND Hospitalization OR Inpatient Care Units OR Intrahospital AND Exercise. The methodological quality of the studies was analyzed by the PEDro scale. Data synthesis: Among the 626 articles found, only 9 fulfilled the inclusion criteria, obtaining a regular methodological quality. The samples had 172 participants, aged 4 to 18 years. Only 6 studies presented both intervention group and control group. The intervention group received strength, aerobic, and muscle stretching exercises, and games, among others. The control group received the standard treatment. The studies varied regarding time, frequency, intensity, and type of exercise. Most studies showed an increase in muscle strength (4/5), followed by an improvement in physical fitness (2/3) and functional capacity (2/4). No adverse events were reported during the interventions. The methodological quality was considered regular. Conclusions: The findings suggest that. during hospitalization of children and adolescents with cancer, exercise improves muscle strength, physical fitness, and functionality.
RESUMO Objetivo: Identificar os efeitos de programas de exercício físico durante a hospitalização de crianças e adolescentes com câncer. Fontes de dados: Trata-se de uma revisão sistemática, realizada nas bases de dados PubMed/Sistema Online de Busca e Análise de Literatura Médica (MEDLINE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), Biblioteca Eletrônica Científica Online (SciELO), Biblioteca Regional de Medicina (BIREME) e Physiotherapy Evidence Database (PEDro). Foram selecionados estudos que incluíram crianças e adolescentes com câncer (sólido ou hematológico) que se submeteram a protocolos de exercício físico durante a hospitalização. Em contrapartida, foram excluídas pesquisas que envolveram pacientes com outras patologias ou com contraindicação médica para o exercício físico. Utilizou-se a seguinte estratégia de busca: Neoplasm OR Leukemia OR Cancer OR Tumor OR Medical Oncology AND Hospitalization OR Inpatient Care Units OR Intrahospital AND Exercise. A qualidade metodológica foi analisada pela escala PEDro. Síntese dos dados: De um total de 626 artigos, somente nove foram incluídos. As amostras totalizaram 172 participantes, com idade entre 4 e 18 anos. Apenas seis artigos apresentaram tanto grupo intervenção como grupo controle. A intervenção consistiu em exercícios de força, aeróbicos, de alongamento muscular, de jogos, entre outros. Já o controle realizou o tratamento padrão da doença. Os protocolos variaram quanto ao tempo, à frequência, à intensidade e ao tipo de exercício. A maioria dos estudos evidenciou aumento na força muscular (4/5), seguido de benefícios na aptidão física (2/3) e na funcionalidade (2/4). Não foi relatado nenhum evento adverso durante as intervenções. A qualidade metodológica foi considerada regular. Conclusões: Os achados sugerem que o exercício físico melhora a força muscular, a aptidão física e a funcionalidade de crianças e adolescentes com câncer durante a hospitalização.

ABSTRACT Objective: To review the effects of the hammock positioning on clinical parameters of preterm newborn infants (PTNB) admitted to the Neonatal Intensive Care Unit (NICU). Data sources: This was a systematic review performed by searching the Pubmed, Lilacs, SciELO and PEDro databases. Intervention studies in English, Portuguese and Spanish that evaluated the effects of hammock positioning on clinical parameters of PTNB admitted to the NICU were selected. Three search strategies were used: 1) hammock positioning OR patient positioning AND intensive care units AND infant, newborn; 2) hammock positioning OR patient positioning AND intensive care units; 3) hammock positioning OR patient positioning AND intensive care units, neonatal. There was no restriction on the year of publication of the articles. Methodological quality was assessed by the PEDro scale. Data synthesis: Among 597 articles, only six were included and 139 neonates with gestational ages between 26 and 37 weeks and an average gestational weight <2240g were analyzed. Four studies included patients without any associated pathology and most of them placed the PTNB supine in hammock positioning. The duration of the intervention ranged from 15 to 180 minutes and most applied it at just one moment. There was an improvement in heart rate (HR), respiratory rate (RR) and pain (3/4 studies), as well as gains in peripheral oxygen saturation (SpO2) (2/4 studies). Only one study reported worsening of SpO2 with the intervention. The methodological quality of the studies was classified as low. Conclusions: Although this review suggests improvement with hammock positioning in HR, RR and pain in PTNB, the low methodological quality makes the results inconsistent.
RESUMO Objetivo: Revisar os efeitos da rede de posicionamento nos parâmetros clínicos de recém-nascidos pré-termo (RNPT) admitidos em Unidade de Terapia Intensiva Neonatal (UTIN). Fontes de dados: Trata-se de uma revisão sistemática realizada na PubMed, na Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), na Biblioteca Eletrônica Científica Online (SciELO) e na Base de Dados em Evidências em Fisioterapia (PEDro). Selecionaram-se estudos de intervenção, nos idiomas inglês, português e espanhol, que avaliaram os efeitos da rede de posicionamento sobre parâmetros clínicos de RNPT admitidos em UTIN. Foram utilizadas três estratégias de busca: hammock positioning OR patient positioning AND intensive care units AND infant, newborn; hammock positioning OR patient positioning AND intensive care units; e hammock positioning OR patient positioning AND intensive care units, neonatal. Não houve restrição quanto ao ano de publicação dos artigos. A qualidade metodológica foi avaliada pela escala PEDro. Síntese dos dados: De um total de 597 artigos, apenas seis foram incluídos. As amostras totalizaram 139 neonatos, com idade gestacional entre 26 e 37 semanas e média de peso gestacional <2.240 g. Quatro estudos incluíram pacientes sem nenhuma patologia associada, e a maior parte deles dispôs os RNPT em supino na rede de posicionamento. A duração da intervenção variou de 15 até 180 minutos, e a maioria aplicou essa intervenção em apenas um momento. Foi observada melhora na frequência cardíaca (FC), na frequência respiratória (FR) e na dor (3/4 estudos), além de ganhos na saturação periférica de oxigênio (SpO2) (2/4 estudos). Apenas um artigo relatou piora da SpO2 com a intervenção. A qualidade metodológica foi classificada como baixa. Conclusões: Embora a rede de posicionamento pareça causar melhora na FC, na FR e na dor em RNPT, a baixa qualidade metodológica torna inconsistentes os resultados.

Objetivo: descrever e comparar as intervenções de fisioterapia respiratória utilizadas para asma durante a hospitalização em três grupos etários pediátricos. Além disso, buscou-se investigar os motivos de escolha dessas intervenções. Métodos: a amostra foi composta por fisioterapeutas atuantes em hospitais que reportaram atender crianças e adolescentes com asma. Os profissionais responderam a um questionário online sobre dados pessoais, acadêmicos, profissionais e relativo às intervenções de fisioterapia respiratória utilizadas em lactentes, pré-escolares e escolares/adolescentes. As intervenções foram agrupadas em nove classificações: convencionais, manuais, baseadas em volume, oscilação oral de alta frequência/pressão expiratória positiva (OOAF/PEP), exercícios ventilatórios, ventilação não invasiva, técnica de expiração forçada (TEF), aspiração de vias aéreas superiores (VAS) e outras. Resultados: foram incluídos 93 fisioterapeutas, com idade entre 31 e 40 anos (47,3%) e do sexo feminino (87,1%). As intervenções mais utilizadas nos lactentes foram a aspiração de VAS (78,5%), a aceleração do fluxo expiratório (AFE) (50,5%) e a terapia expiratória manual passiva (TEMP) (45,2%). Nos pré-escolares, predominou a tosse (75,3%), a aspiração de VAS (52,7%), a AFE (51,6%) e a TEMP/expiração lenta e prolongada (ELPr) (50,5%). Já nos escolares/adolescentes, a tosse (83,9%), os exercícios expiratórios variados (73,1%) e a ELPr (57,0%) sobressaíram-se. Houve menor utilização (p<0,01) de OOAF/PEP, de exercícios ventilatórios e de TEF nos lactentes e, também, de métodos convencionais, manuais, aspiração de VAS e outras terapias (p<0,01) nos escolares/adolescentes. Os profissionais relataram utilizar essas intervenções por serem mais eficazes na prática clínica (78,5%). Conclusão: as intervenções manuais e as técnicas de expectoração visando à desobstrução brônquica foram as mais frequentemente utilizadas, tendo relação com a faixa etária e a escolha devido à efetividade na prática clínica.
Aims: to describe and to compare the airway clearance techniques used for asthma during hospitalization in three pediatric age groups. In addition, we sought to investigate the main reasons for choosing the interventions.Methods: the sample consisted of physiotherapists working in hospitals who reported attending children and adolescents with asthma. The professionals answered an online questionnaire on personal, academic and professional data, as well as regarding the airway clearance techniques used in, preschoolers and schoolchildren/adolescents. The interventions were grouped into nine classifications: conventional, manual, volume-based, high-frequency oral oscillation/positive expiratory pressure (HFOO/PEP), ventilatory exercises, non-invasive ventilation, forced expiratory technique (FET), upper airway aspiration (UAA) and others. Results: nine-three physiotherapists were included, aged between 31 and 40 years (47.3%) and female (87.1%). The most frequent interventions in infants were UAA (78.5%), expiratory flow acceleration (EFA) (50.5%) and chest compression (45.2%). In preschoolers, coughing (75.3%), aspiration of upper airways (52.7%), EFA (51.6%) and chest compression/slow and prolonged expiration (SPE) (50.5%) were the most used. In schoolchildren/adolescents, coughing (83.9%), varying expiratory exercises (73.1%) and SPE (57.0%) were the most frequent. There was less use (p<0.01) of OOAF/PEP, ventilatory and FET exercises in infants and also of conventional, manual methods, aspiration of UUA and other therapies (p<0.01) in schoolchildren/adolescents. The professionals reported using these interventions because they are more effective in clinical practice (78.5%). Conclusions: manual and expectoration techniques aiming at airway clearance were the most frequently used, being related to the age group and chosen due to effectiveness in clinical practice.

Objetivos: avaliar a frequência de alterações espirométricas e pletismográficas em crianças e adolescentes com asma grave resistente à terapia (AGRT). Além disso, testaram-se possíveis associações entre esses desfechos. Métodos: trata-se de um estudo retrospectivo, no qual foram incluídas crianças e adolescentes (6-18 anos), com diagnóstico de AGRT, e que se encontravam em acompanhamento ambulatorial regular. Todos deveriam possuir informações antropométricas (peso, altura, índice de massa corporal), demográficas (idade, etnia e sexo), clínicas (teste cutâneo, teste de controle da asma, tabagismo familiar e medicações em uso) e de função pulmonar (espirometria e pletismografia corporal) registradas no banco de dados do serviço. Os testes de função pulmonar seguiram as recomendações das diretrizes nacionais e internacionais. Para fins estatísticos, utilizou-se análise descritiva e o teste de qui-quadrado de Pearson. Resultados: de um total de 15 pacientes com AGRT, 12 deles foram incluídos na amostra. A média de idade foi de 12,2 anos, com predomínio do sexo feminino (66,7%). Destes, 50,0% apresentaram a doença controlada, 83,3% foram considerados atópicos e 50,0% tinham histórico de tabagismo familiar. Em relação aos testes de função pulmonar (% do previsto), as médias dos parâmetros espirométricos e de plestismografia corporal encontraram-se dentro dos limites inferiores da normalidade. Apenas 16,7% da amostra apresentou espirometria alterada (
Aims: to assess the frequency of spirometric and plethysmographic changes in children and adolescents with severe therapy-resistant asthma (SRTA). In addition, possible associations between these outcome were tested. Methods: this is a retrospective study. Children and adolescents (6-18 years old), diagnosed with SRTA and who were in regular outpatient follow-up were included. Everyone should have anthropometric (weight, height, body mass index), demographic (age, ethnicity and gender), clinical (skin test, asthma control test, family smoking and medications in use) and pulmonary function (spirometry and body plethysmography) recorded in the service's database. Pulmonary function tests followed the recommendations of national and international guidelines. For statistical purposes, descriptive analysis and Pearson's chi-square test were used. Results: from a total of 15 patients with SRTA, 12 of them were included in the sample. The average age was 12.2 years, with a predominance of females (66.7%). Of these, 50.0% had the disease under control, 83.3% were considered atopic, and 50.0% had a family history of smoking. Regarding the pulmonary function tests (% of predicted), the means of spirometric parameters and body plestismography were within the lower limits of normality. Only 16.7% of the sample had altered spirometry (<5th percentile), 25.0% air trapping (residual volume>130.0%) and 16.7% pulmonary hyperinflation (total lung capacity>120.0%). There was a statistically higher frequency (p=0.045) of air trapping in participants with altered spirometry, compared to normal spirometry. However, there was no difference (p=0.341) in relation to pulmonary hyperinflation. Conclusions: the findings demonstrated little impairment of spirometry and lung volumes and capacities in children and adolescents with AGRT. In addition, those participants with altered spirometry had a higher frequency of air trapping in the body plethysmography exam.

DATA SYNTHESIS: Among 597 articles, only six were included and 139 neonates with gestational ages between 26 and 37 weeks and an average gestational weight <2240g were analyzed. Four studies included patients without any associated pathology and most of them placed the PTNB supine in hammock positioning. The duration of the intervention ranged from 15 to 180 minutes and most applied it at just one moment. There was an improvement in heart rate (HR), respiratory rate (RR) and pain (3/4 studies), as well as gains in peripheral oxygen saturation (SpO2) (2/4 studies). Only one study reported worsening of SpO2 with the intervention. The methodological quality of the studies was classified as low. CONCLUSIONS: Although this review suggests improvement with hammock positioning in HR, RR and pain in PTNB, the low methodological quality makes the results inconsistent.

OBJECTIVE: To identify the effects of exercise programs during hospitalization on children and adolescents with cancer. DATA SOURCE: This is a systematic review, carried out in PubMed/ Medical Literature Analysis and Retrieval System Online (MEDLINE), Latin American and Caribbean Health Sciences Literature (LILACS), Scientific Electronic Library Online (SciELO), Latin American and Caribbean Center on Health Sciences Information (BIREME), and Physiotherapy Evidence Database (PEDro). We selected studies that included children and adolescents diagnosed with cancer (solid or hematologic) and submitted to exercise protocols during hospitalization. Studies involving patients with other pathologies or with a medical contraindication for exercise were excluded. We used the following search strategy: Neoplasm OR Leukemia OR Cancer OR Tumor OR Medical Oncology AND Hospitalization OR Inpatient Care Units OR Intrahospital AND Exercise. The methodological quality of the studies was analyzed by the PEDro scale. DATA SYNTHESIS: Among the 626 articles found, only 9 fulfilled the inclusion criteria, obtaining a regular methodological quality. The samples had 172 participants, aged 4 to 18 years. Only 6 studies presented both intervention group and control group. The intervention group received strength, aerobic, and muscle stretching exercises, and games, among others. The control group received the standard treatment. The studies varied regarding time, frequency, intensity, and type of exercise. Most studies showed an increase in muscle strength (4/5), followed by an improvement in physical fitness (2/3) and functional capacity (2/4). No adverse events were reported during the interventions. The methodological quality was considered regular. CONCLUSIONS: The findings suggest that. during hospitalization of children and adolescents with cancer, exercise improves muscle strength, physical fitness, and functionality.

Objective To evaluate the effect of an interdisciplinary intervention with a motivational approach on exercise capacity and usual physical activity levels in overweight and obese adolescents. Methods This is a randomized, controlled clinical trial with single blinding of subjects. Adolescents aged 15 to 18 years with overweight and obesity (body mass index ≥ 85 percentile) were included. The adolescents were randomized into two groups: interdisciplinary intervention or control - traditional approach aiming at lifestyle modifications. The initial evaluations were carried out, including the cardiopulmonary exercise test and the physical activity level measurement by using the International Physical Activity Questionnaire and a pedometer. The evaluations were performed in two moments: time zero (time of inclusion in the study) and after 3 months (end of intervention). There were 12 sessions with weekly meetings. Results A total of 37 participants were included, 19 in the Intervention Group. There were no significant differences in the baseline demographic, anthropometric and physical activity characteristics between groups, with mean age of 17.3±1.0 years in the Control Group, and 16.8±0.9 years in the Intervention Group (p=0.14). The motivational intervention did not cause significant differences (p>0.05) in the comparison of the variables of exercise capacity and usual physical activity (questionnaire and pedometer) between groups. Conclusion The intervention with a motivational approach did not alter exercise capacity and levels of usual physical activity in overweight and obese adolescents. Clinical Trial Registry: NCT02455973 and REBEC: RBR-234nb5.

BACKGROUND: Patients with cystic fibrosis develop decreased exercise capacity. However, the main factors responsible for this decline are still unclear. Thus, the objective of this study was to evaluate the factors influencing exercise capacity assessed with the modified shuttle test (MST) in individuals with cystic fibrosis. METHODS: A cross-sectional study was carried out in subjects with a diagnosis of cystic fibrosis who were 6-26 y old and were regularly monitored at 2 cystic fibrosis reference centers in Brazil. Individuals who were unable to perform the tests or who exhibited hemodynamic instability and exacerbation of respiratory symptoms were excluded. Anthropometric, clinical, and genotype data were collected. In addition, lung function and exercise capacity were evaluated with the MST. RESULTS: 73 subjects (mean age 12.2 ± 4.9 y and FEV1 76.8 ± 23.3%) were included. The mean distance achieved in the MST was 765 ± 258 m (71.6% of predicted). The distance achieved on the MST correlated significantly with age (r = 0.49, P < .001), body mass index (r = 0.41, P < .001), resting heart rate (r = -0.51, P < .001), and FEV1 (r = 0.24, P = .042). Subjects with FEV1 > 67% of predicted (P = .02) and those with resting heart rate < 100 beats/min (P = .01) had a greater exercise capacity. Resting heart rate, age, and FEV1 (%) were found as significant variables to explain the distance achieved on the MST (R2 = 0.48, standard error = 191.0 m). CONCLUSIONS: The main determinants of exercise capacity assessed with the MST in individuals with cystic fibrosis were resting heart rate, age, and lung function.

BACKGROUND: Adherence of patients with cystic fibrosis (CF) to exercise is challenging. Here we compared the physiological responses during the use of interactive video games (VG) with the cardiopulmonary exercise test (CPET) in healthy and CF subjects. METHODS: Cross-sectional study including CF and healthy (CON) subjects older than 6 years. Individuals were evaluated in two visits. At visit one, anthropometric measures, spirometry and CPET were performed. In the second visit, a physical activity questionnaire was applied and gas analyses performed during the use (10 min) of both Nintendo Wii (Wii Fit Plus: (1) Obstacle Course, (2) Rhythm Boxing and (3) Free Run) and Xbox One (Just Dance 2015: (1) Love Me Again, (2) Summer and (3) Happy). RESULTS: Twenty-five CON and 30 CF patients were included. The mean FEV1 (%) was significantly lower in the CF group compared to CON. There were no differences between groups at peak exercise (CPET) for heart rate (HR), oxygen consumption (VO2) and minute ventilation (VE). In the CON group, games 2 and 3 (Xbox) and game 3 (Nintendo) increased HR to values similar to the anaerobic threshold (AT), while for the CF group this occurred for games 2 (Xbox) and 3 (Nintendo). As for VO2 and VE, both groups obtained similar responses as compared to AT values in games 2 (Xbox) and 3 (Nintendo). CONCLUSION: The use of VG generated a cardiorespiratory response similar to AT levels found during CPET, indicating that it may be an alternative for exercise training of CF individuals.

RESUMO Objetivo Avaliar o efeito de uma intervenção interdisciplinar com abordagem motivacional na capacidade de exercício e no nível de atividade física habitual em adolescentes com sobrepeso e obesidade. Métodos Trata-se de ensaio clínico controlado, randomizado, com cegamento único dos indivíduos. Foram incluídos adolescentes com idade entre 15 e 18 anos, com sobrepeso e obesidade (índice de massa corporal ≥ percentil 85). Os adolescentes foram randomizados em dois grupos: intervenção interdisciplinar motivacional ou controle − abordagem tradicional, visando à modificação do estilo de vida. Foram realizadas as avaliações iniciais incluindo o teste de exercício cardiopulmonar e a aferição do nível de atividade física por meio do International Physical Activity Questionnaire e do pedômetro. As avaliações foram realizadas em dois momentos, no tempo zero (inclusão no estudo) e após 3 meses (término da intervenção). Foram realizadas 12 sessões com encontros semanais. Resultados Foram incluídos 37 participantes, sendo 19 no Grupo Intervenção. Não houve diferenças significativas nos dados basais de características demográficas, antropométricas e de atividade física entre os grupos, e a média de idade foi de 17,3±1,0 anos no Grupo Controle e 16,8±0,9 anos no Intervenção (p=0,14). A intervenção motivacional não provocou diferenças significativas (p>0,05) na comparação das variáveis de capacidade de exercício e atividade física habitual (questionário e pedômetro) entre os grupos. Conclusão A intervenção com abordagem motivacional não alterou a capacidade de exercício e os níveis de atividade física habitual em adolescentes com sobrepeso e obesidade.

Objetivos: verificar o número e as causas de hospitalizações por quedas em idosos brasileiros, além dos gastos federais do Sistema Único de Saúde (SUS), no período de 2000 a 2018. Métodos: trata-se de um estudo ecológico, utilizando informações disponíveis na base de dados do Departamento de Informática do SUS. Foram coletados dados de idosos (≥60 anos) que internaram no SUS devido às quedas no período de 2000 a 2018 no Brasil. Extraíram-se o número de hospitalizações no País e nas regiões (Norte, Nordeste, Sul, Sudeste e Centro-Oeste), as causas das quedas (Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde 10) e o valor de gastos federais. Para fins estatísticos, utilizou-se análise descritiva. Resultados: totalizaram-se 1,48 milhões de hospitalizações por quedas em idosos no Brasil, com uma taxa de 38,6 a cada 10 mil. As principais causas desses registros no DATASUS foram as "quedas sem especificações", as "outras quedas no mesmo nível" e as "quedas no mesmo nível por escorregão, tropeção ou passos em falsos". Em relação às localidades, os idosos pertencentes às regiões Sudeste (47,1), Sul (44,1) e Centro-Oeste (40,4) foram aqueles que apresentaram maiores medianas das taxas de hospitalizações por quedas no período analisado. Entretanto, o Nordeste (variação%=0,4), o Sul (variação%=0,2) e o Centro-Oeste (variação%=0,2) demonstraram maiores elevações desse indicador ao longo dos 18 anos, enquanto apenas a região Norte apresentou redução (variação%=-0,5). A mediana de gastos hospitalares federais (milhões) foi de R$135,58, variando de R$112,89 até R$194,98. Conclusões: houve aumento das taxas de hospitalizações por quedas em idosos no SUS em quase todas as unidades federativas. As causas mais frequentes foram as "quedas sem especificações", as "outras quedas no mesmo nível" e as "quedas no mesmo nível por escorregão, tropeção ou passos em falsos". Além disso, ocorreu elevação dos gastos hospitalares federais ao longo do período no País.
Aims: to verify the number and causes of hospitalizations for falls in Brazilian elderly, in addition to the federal expenses of the Unified Health System (SUS), in the period from 2000 to 2018. Methods: this is an ecological study, using information available in the database of the SUS Department of Informatics. Data were collected from elderly (≥60 years) who were admitted to SUS due to falls in the period from 2000 to 2018 in Brazil. The number of hospitalizations in the country and in the regions (North, Northeast, South, Southeast and Midwest), the causes of falls (International Statistical Classification of Diseases and Related Health Problems 10) and the amount of federal spending were extracted. For statistical purposes, descriptive analysis was used. Results: there were 1.48 million hospitalizations for falls in the elderly in Brazil, with a rate of 38.6 per 10,000. The main causes of these records in DATASUS were "falls without specifications", "other falls on the same level" and "falls on the same level due to slips, trips or false steps". Regarding the locations, the elderly belonging to the Southeast (47.1), South (44.1) and Midwest (40.4) regions were those who had the highest median hospitalization rates for falls in the analysed period. However, the Northeast (variation%=0.4), the South (variation%=0.2) and the Midwest (variation%=0.2) showed greater increases in this indicator over the age of 18, while only the North region showed a reduction (variation%=-0.5). The median federal hospital expenses (million) was R$135.58, ranging from R$112.89 to R$194.98. Conclusions: there was an increase in hospitalization rates due to falls in the elderly in SUS, in almost all federative units. The most frequent causes were "falls without specifications", "other falls on the same level" and "falls on the same level due to slips, trips or false steps". In addition, there was an increase in federal hospital spending over the period in the country.

INTRODUCTION: Several tests may be used to assess exercise intolerance in severe therapy-resistant asthma (STRA), including the gold standard cardiopulmonary exercise test (CPET) and the modified shuttle test (MST). OBJECTIVE: To correlate the distance achieved in the MST with peak oxygen uptake (VO2peak) and to compare the maximal heart rate (HRmax) obtained in both tests in children and adolescents with STRA. METHODS: This is a cross-sectional study, with 19 children and adolescents with STRA. Demographic, anthropometric, clinical data, and spirometric values were collected. CPET and the MST were performed in two consecutive visits. HRmax, pulse oxygen saturation, and dyspnea were compared between tests. The distance achieved in the MST was correlated with VO2peak. RESULTS: Nineteen patients with a mean age of 11.5 ± 2.5 years were included. The mean HRmax (bpm) achieved was 180.8 ± 12.10 for the MST and 187.6 ± 9.35 for CPET, whereas the mean HRmax as a percentage of predicted (HRmax%) was 90.7 ± 6.5 for the MST and 93.8 ± 4.5 for CPET. A difference of only 6 bpm was found for HRmax (p = 0.10) and of 3% for HRmax% (p = 0.06) between tests. A strong correlation was found between the MST (r = 0.79; p = 0.001) and VO2peak measured through CPET. However, there were no correlations between the MST and both body mass index (r = -0.14; p = 0.564) and forced expiratory volume in the first second - FEV1 (r = -0.02; p = 0.917). CONCLUSION: The results demonstrate that the MST distance strongly correlates with VO2peak, measured through CPET, and the main physiological variable responses were similar between both tests. Our results provide additional data for the use of the MST to assess exercise capacity in children and adolescents with STRA.
RESUMEN
ABSTRACT Objective: To evaluate exercise capacity in children and adolescents with post-infectious bronchiolitis obliterans. Data source: This is a systematic review based on data from PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO), and Physiotherapy Evidence Database (PEDro). We used the following search strategy: "Exercise capacity OR Exercise Test OR Physical fitness OR Functional capacity OR Six-minute walk test OR Shuttle walk test OR Cardiopulmonary exercise test AND Bronchiolitis obliterans." We selected studies that evaluated exercise capacity through maximal/submaximal testing in children and adolescents with post-infectious bronchiolitis obliterans, and no other associated disease. We searched articles in English, Portuguese, and Spanish, without restrictions regarding the period of publication. The methodological quality was assessed by the Agency for Healthcare Research and Quality (AHRQ) protocol. Data synthesis: Out of the 81 articles found, only 4 were included in this review. The studies totaled 135 participants (121 with post-infectious bronchiolitis obliterans and 14 healthy), with sample sizes between 14 and 58 subjects. All patients underwent spirometry to evaluate pulmonary function, indicating an obstructive ventilatory pattern. Among them, 3/4 had their physical performance assessed by the six-minute walk test and 2/4 by the cardiopulmonary exercise testing. These test results were compared to those of a control group (1/4) and presented as percentage of predicted and/or in meters (3/4). Lastly, 3/4 of the studies showed reduced exercise capacity in this population. The studies included were classified as having high methodological quality. Conclusions: Findings of the study demonstrate that children and adolescents with post-infectious bronchiolitis obliterans have reduced exercise capacity.
RESUMO Objetivo: Avaliar a capacidade de exercício em crianças e adolescentes com bronquiolite obliterante pós-infeciosa. Fonte de dados: Trata-se de uma revisão sistemática por meio das bases de dados PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO) e Physiotherapy Evidence Database (PEDro). Utilizou-se a seguinte estratégia de busca: "Exercise capacity OR Exercise Test OR Physical fitness OR Functional capacity OR Six minute walk test OR Shuttle walk test OR Cardiopulmonary exercise test AND Bronchiolitis obliterans". Foram selecionados estudos que avaliaram a capacidade de exercício por meio de testes máximos/submáximos em crianças e adolescentes com bronquiolite obliterante pós-infeciosa, sem qualquer outra doença associada. Buscaram-se artigos nos idiomas inglês, português e espanhol e sem restrições quanto ao período de publicação. A qualidade metodológica foi avaliada pelo protocolo da Agency for Health Care Research and Quality (AHRQ). Síntese dos dados: De um total de 81 artigos, apenas 4 foram incluídos nesta revisão. Os estudos totalizaram 135 participantes (121 com bronquiolite obliterante pós-infeciosa e 14 saudáveis), com tamanho amostral entre 14 e 58 sujeitos. Todos avaliaram a função pulmonar por meio da espirometria, observando um padrão ventilatório obstrutivo. Desses, 3/4 avaliaram o desempenho físico pelo teste de caminhada de seis minutos e 2/4 pelo teste de exercício cardiopulmonar. Os resultados desses testes foram comparados a um grupo controle (1/4), bem como apresentados em percentual do previsto e/ou em metros (3/4). Por fim, 3/4 dos estudos demostraram que a capacidade de exercício se encontra reduzida nessa população. Os estudos incluídos foram classificados com alta qualidade metodológica. Conclusões: Os achados do estudo demonstram que crianças e adolescentes com bronquiolite obliterante pós-infeciosa apresentam redução da capacidade de exercício.
