Pulmonary rehabilitation (PR) is a mandatory component of a comprehensive treatment of patients with chronic respiratory disease. However, there is no officially published data about PR Centers in Latin America. The objetive is to identify Latin American Pulmonary Rehabilitation Centers and evaluate their characteristics and organizational aspects. A cross-sectional study with the Pulmonary Rehabilitation Centers indicated by the Latin American Respiratory and Physiotherapy Societies and by our own personal survey among physicians and physiotherapists. An eletronic transmission questionnaire with 20 questions was sent to the Coordinator of each one of the Centers. 217 Pulmonary Rehabilitation Centers were found throughout Latin America and a total of 160 (73.7%) Centers answered the questionnaire. Of these, 65.8% had private administration; 68.8% had an associated program for patients with heart disease; programs lasted an average of 24 sessions; the rehabilitation team consisted mainly of physiotherapists, physicians and dietitians; 90.6% of the centers evaluated the patients with different questionnaires; 91.9% used treadmill and 90.6% bicycle for exercises of lower limbs and 80.1% proprioceptive neuromuscular facilitation technique with weights to train the upper limbs of their patients; 55.6% had an educational program and 36.9% presented a home-based program. There has been a great increase in the number of Latin American Pulmonary Rehabilitation Centers, presenting diversity in organizational aspects.

Background Asthma is a chronic airway inflammatory condition of the airway and is classified as controlled, partially controlled, and uncontrolled. Patients with uncontrolled asthma are at greater risk for hospitalizations and visits to emergencies, and the condition has greater impact on their daily lives. The aim of this study was to evaluate asthma control, the use of health resources, and asthma's impact on the activities of daily living of patients with different age groups in 5 Latin American countries. Methods This was a retrospective analysis of The Latin America Asthma Insights and Management (LA AIM) study carried out in Argentina, Brazil, Mexico, Venezuela, and Puerto Rico. Asthmatics were splited into 3 age groups: 12–17, >17–40 and > 40 years old. An interview face to face was carried out and patients answered a questionnaire of 53 questions related to 5 main domains of asthma: symptoms, impact of asthma on daily living activities, patients' perceptions of asthma control, exacerbations, and treatment/medication. Results A total of 2167 asthmatics were interviewed. There was a low percentage of controlled patients (mean 9%) in all 3 groups with no particular difference among the five countries, but Venezuelan patients had a 71% chance of having uncontrolled asthma (p Conclusion In the 3 age groups, patients experienced poor asthma control, with no significant differences among the countries. Patients who used control medication had a greater chance of controlling their asthma, and those who had emergency health care visits had a greater chance of having uncontrolled asthma.

The Glittre ADL-test is based on important and common activities of daily living (ADLs), and it is an useful test to objectively distinguish patients with and without self-reported functional limitations. This study aims to analyze if difficulty to perform ADLs, as self-reported by patients with COPD, would reflect a worse Glittre ADL-test performance. In the first visit, patients were evaluated for clinical and nutritional status, spirometry, maximal cardiopulmonary exercise test on a treadmill. One week later, the patients performed two Glittre ADL-tests. Maximal voluntary ventilation (MVV) and the VE

BACKGROUND: The Glittre activities of daily living (ADL) test is supposed to evaluate the functional capacity of COPD patients. The physiological requirements of the test and the time taken to perform it by COPD patients in different disease stages are not well known. The objective of this work was to compare the metabolic, ventilatory, and cardiac requirements and the time taken to carry out the Glittre ADL test by COPD subjects with mild, moderate, and severe disease. METHODS: Spirometry, Medical Research Council questionnaire, cardiopulmonary exercise test, and 2 Glittre ADL tests were evaluated in 62 COPD subjects. Oxygen uptake (VO2), carbon dioxide production, pulmonary ventilation, breathing frequency, heart rate, SpO2, and dyspnea were analyzed before and at the end of the tests. Maximum voluntary ventilation, Glittre peak VO2/cardiopulmonary exercise test (CPET) peak VO2, Glittre VE/maximum voluntary ventilation, and Glittre peak heart rate/CPET peak heart rate ratios were calculated to analyze their reserves. RESULTS: Subjects carried out the Glittre ADL test with similar absolute metabolic, ventilatory, and cardiac requirements. Ventilatory reserve decreased progressively from mild to severe COPD subjects (P CONCLUSIONS: As the degree of air-flow obstruction progresses, the COPD subjects present significant lower ventilatory reserve to perform the Glittre ADL test. In addition, metabolic and cardiac reserves may differentiate the severe subjects. These variables may be better measures to differentiate functional performance than Glittre ADL time.

Oxygen therapy is essential in clinical practice and should be correctly adjusted to avoid deleterious effects resulting from lack or excess of gas. Objective: To evaluate the accuracy and precision of neonatal and pediatric oxygen flowmeters. Methods: 160 oxygen flowmeters from six different countries were divided into two groups: 100 neonatal flowmeters (range from 0 to 1L/min and from 0 to 3.5 L/min), tested on following flows 0.1, 0.3, 0.5, 1L/min and 0.5, 1, 1.5, 2 L/min respectively and 60 pediatric flowmeters (range from 0 to 5 L/min and from 0 to 8L/min), tested on following flows 0.5, 1, 3 and 5 L/min. Flowmeters were evaluated from one single oxygen system outlet containing a reduction valve and connected to it, a flow analyzer. All measures were set to zero before the oxygen flow starts and the flowmeter central metal sphere was positioned at corresponding mark of preset flow value. After 30 seconds the measured flow was read on the flow analyzer. Three measurements were performed in each flow. Flowmeter was considered accurate when the variation among three measures was not exceed 10% variation and it was considered precise with no more than 10% difference among the three repeated measures (1stvs2nd, 1stvs3rd, 2ndvs3rd). Results: There was a significant difference among the measurements from different flowmeters (p Conclusion: Flowmeters from different countries presented low accuracy and high precision.

Oxygen flowmeter is an equipment used to control oxygen flow delivery in patients undergoing oxygen therapy. Objective: To evaluate accuracy and precision of oxygen flowmeters used in adult care. Methods:In vitro experimental study that evaluated 160 oxygen flowmeters (Flow range 0 to 15L/min), without previous use, manufactured in eight different countries (Australia, Brazil, Canada, China, England, France, Italy and United States of America). Flowmeters were tested at four flow rates, 1, 3, 5 and 10 L/min, with three repeated measurements in each flow. During the tests, the flowmeters were connected to the gas system through a reduction valve and a flow analyzer (FlowAnalyzer™ PF-302; Imtmedical Ag. Buchs Switzerland). The float (metal sphere) of the flowmeter was set to zero and then was kept at the corresponding mark of the flow to be tested. Was considered accurate flowmeter that maintained the three measurements within a ±10% variation, and precise, flowmeter that present no difference greater than 10% among repeated measurements (1st vs 2nd, 1st vs 3rd, 2nd vs 3rd). Results: The accuracy percentage in the low-flows (1 and 3L/min) was significantly lower than in the high-flows (5 and 10L/min). Flowmeters samples showed high precision in all tested flows (65 to 100%), specially at flows rate 5 and 10L/min (100%). None of the set of the flowmeters met the ideal expectation of 100% combined of accuracy and precision flows in all four tested. Conclusion: None of the eight different countries samples presented accurate and precision for all four tested flows. The flowmeters precision percentage was high despite their low accuracy.

Introduction: Chronic thromboembolic hypertension (CTEPH) patients present decreased aerobic capacity during cardiopulmonary exercise test (CPET) with lower limbs (LL). It is not known if CTEPH patients present the same decreased aerobic capacity during upper limbs (UL) test. Objective: To investigate the response of a UL maximal test on cycloergometer in CTEPH patients and control group and compare to a CPET. Methods: The cross-sectional study including 33 CTEPH patients (54.5% male, 46.5 ± 14.2 years, 33% NYHA FC III and IV) and 22 controls (40.9% male, 39.8 ± 10.9 years). All patients underwent a UL and LL CPET cycloergometer measuring ventilation and gas exchange at peak exercise. Results: The oxygen consuption (VO2) of a UL maximal test of CTEPH patients (815.9 ± 212.7 mL/min) was lower than controls (1066.8 ± 340.2 mL/min) (p=0.004) and corresponded to 76% of the control group. The UL VO2 of CTEPH patients corresponded to 86% of their VO2max in a CPET and to 68% in the control group (p Conclusion: The aerobic capacity of UL in CTEPH patients is lower than a matched sex and age control group and worse physiological responses were observed in the CTEPH patients.

Fractures are common in individuals with COPD and occur at higher bone mass values than expected. COPD appears to be an important risk factor for bone fragility. Patients with chronic obstructive pulmonary disease (COPD) have an increased risk of osteoporosis and fractures, but screening and prophylactic measures to prevent both disorders are often neglected in this population. This case-control study assessed the prevalence of osteopenia, osteoporosis, and fractures in patients with COPD, and identified potential risk factors for fractures in this population. Overall, 91 patients with COPD (COPD group; COPDG) and 81 age- and sex-matched controls (control group; CG) were assessed with bone mineral density (BMD), thoracic/lumbar spine radiographs, and serum PTH and 25-hydroxyvitamin D (25[OH]D) levels. The occurrence of prior fractures was retrieved from clinical history. The prevalence of total fractures in the COPDG was 57.1% (odds of fracture 4.7 times greater compared with the CG), and the femoral neck T-score emerged as the best predictor of fractures. Compared with the CG, the COPDG had lower spine and femoral BMD (p ≤ 0.01) and 25(OH)D levels (p = 0.01) and 2.6 times greater odds of osteoporosis. Among men, vertebral fractures were more prevalent in the COPDG versus CG (25.9% vs. 6.5%, respectively, p = 0.01). The odds of fracture increased with femoral neck T-scores ≤ − 2.7 in the CG and ≤ − 0.6 in the COPDG. These results add robust evidence to an increased odds of osteoporosis and fractures in COPD. Fractures in the COPDG occurred at higher BMD values than expected, suggesting that COPD may be an independent marker of fracture risk, reinforcing a need for regular osteoporosis screening with BMD measurement and prophylaxis of fractures in patients with this disorder.

BACKGROUND: No specific quality-of-life scale for stroke patients has previously been translated and evaluated for reproducibility, for use in the Portuguese language. Internationally, the instrument for this purpose is the Stroke Impact Scale 2.0 (SIS). Use of of SIS enables comprehensive analysis on the impact of mild and moderate stroke on patients’ lives. The aims here were to translate SIS into Portuguese, adapt it culturally, evaluate its reproducibility and correlate it with SF-36 among stroke patients. DESIGN AND SETTING: Translation and validation study. METHODS: The process of initial and retrograde translation was performed, in addition to cultural adaptation to the Brazilian language and culture. SIS was applied to 40 patients, who answered the questions three times. On the first day, the scale was applied twice by two independent researchers (to evaluate interobserver reproducibility). Fifteen days later, the scale was applied for a third time by another researcher (intraobserver reproducibility). The intraclass correlation coefficient (ICC) was used to measure the reproducibility of the SIS scale. RESULTS: The reproducibility of the whole scale was very good (ICC: 0.73 to 0.99). Intraobserver reproducibility in all domains was also very good (ICC: 0.85 to 0.95). Comparison of SIS with SF-36 showed that the domains of strength, mobility and activities of daily living (ADLs) correlated moderately with the functional capacity domain, as did the ADL domain with general health status. The other correlations were weak. The depression domain showed a moderate negative correlation with the memory and communication domains. CONCLUSION: The translation of the SIS 2.0 scale was easy to understand and it had good reproducibility among stroke patients.

Although the internet is an important tool for entertainment, work, learning, shopping, and communication, it is also a possible source for information on health and disease. The aim of this study was to evaluate the proportion of subjects with COPD in São Paulo, Brazil, who use the internet to obtain information about their disease.Subjects (N = 382) with COPD answered a 17-question survey, including information regarding computer use, internet access, and searching for sites on COPD. Our sample was distributed according to the socioeconomic levels of the Brazilian population (low, 17.8%; medium, 66.5%; and high, 15.7%).Most of the subjects in the sample were male (62.6%), with a mean age of 67.0 ± 9.9 y. According to Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages, 74.3% of the subjects were in stage II or III. In addition, 51.6% of the subjects had a computer, 49.7% accessed the internet, and 13.9% used it to search for information about COPD. The internet was predominantly accessed by male (70.3%) and younger (64.6 ± 9.5 y of age) subjects compared with female (29.7%, P = .04) and older (67.5 ± 9.6 y of age, P.007) subjects. Searching for information about COPD on the internet was associated with having a computer (5.9-fold), Medical Research Council dyspnea level 1 (5.3-fold), and high social class (8.4-fold). The search for information on COPD was not influenced by GOLD staging.A low percentage of subjects with COPD in São Paulo use the internet as a tool to obtain information about their disease. This search is associated with having a computer, low dyspnea score, and high socioeconomic level.

Objective: To evaluate the impact of asthma on patients in Brazil, by age group (12-17 years, 18-40 years, and ≥ 41 years). Methods: From a survey conducted in Latin America in 2011, we obtained data on 400 patients diagnosed with asthma and residing in one of four Brazilian state capitals (São Paulo, Rio de Janeiro, Curitiba, and Salvador). The data had been collected using a standardized questionnaire in face-to-face interviews. For the patients who were minors, the parents/guardians had completed the questionnaire. The questions addressed asthma control, number of hospitalizations, number of emergency room visits, and school/work absenteeism, as well as the impact of asthma on the quality of life, sleep, and leisure. We stratified the data by the selected age groups. Results: The proportions of patients who responded in the affirmative to the following questions were significantly higher in the 12- to 17-year age group than in the other two groups: "Have you had at least one episode of severe asthma that prevented you from playing/exercising in the last 12 months?" (p = 0.012); "Have you been absent from school/work in the last 12 months?" (p < 0.001); "Have you discontinued your asthma relief or control medication in the last 12 months?" (p = 0.008). In addition, 30.2% of the patients in the 12- to 17-year age group reported that normal physical exertion was very limiting (p = 0.010 vs. the other groups), whereas 14% of the patients in the ≥ 41-year age group described social activities as very limiting (p = 0.011 vs. the other groups). Conclusions: In this sample, asthma had a greater impact on the patients between 12 and 17 years of age, which might be attributable to poor treatment compliance. Objetivo: Avaliar o impacto da asma em pacientes segundo as faixas etárias de 12-17 anos, 18-40 anos e ≥ 41 anos no Brasil. Métodos: Os dados de 400 pacientes com asma diagnosticada por um médico e residentes de quatro capitais estaduais brasileiras (São Paulo, Rio de Janeiro, Curitiba e Salvador) foram obtidos em um inquérito realizado em países da América Latina em 2011. Os dados foram coletados por meio de um questionário padronizado em entrevista presencial com os pacientes ou com os pais/responsáveis daqueles < 18 anos. As questões abordavam controle da asma, número de hospitalizações, número de consultas de urgência, absenteísmo na escola/trabalho e impactos da asma na qualidade de vida, sono e lazer. Os dados foram estratificados pelas faixas etárias selecionadas. Resultados: Em comparação com os grupos de pacientes adultos, houve uma proporção significativamente maior no grupo 12-17 anos em relação a ter ao menos um episódio de asma grave que impediu o paciente a continuar a jogar ou a se exercitar nos últimos 12 meses (p = 0,012), absenteísmo escolar/trabalho nos últimos 12 meses (p < 0,001), e interrupção de medicação para controle ou prevenção da asma nos últimos 12 meses (p = 0,008). Além disso, 30,2% dos pacientes na faixa etária 12-17 anos relataram que esforços físicos normais eram atividades muito limitantes (p = 0,010 vs. outros grupos), enquanto 14% dos pacientes do grupo ≥ 41 anos descreveram as atividades sociais como muito limitantes (p = 0,011 vs. outros grupos). Conclusões: Nessa amostra, o impacto da asma foi maior nos pacientes com idade entre 12 e 17 anos do que nos adultos, e isso pode ser atribuído à baixa aderência ao tratamento.

OBJECTIVE: To evaluate the impact of asthma, by gender, in a population sample of asthma patients in Brazil. METHODS: We conducted face-to-face interviews with 400 subjects (> 12 years of age) included in a national probability telephone sample of asthma patients in the Brazilian state capitals of São Paulo, Rio de Janeiro, Curitiba, and Salvador. Each of those 400 subjects completed a 53-item questionnaire that addressed five asthma domains: symptoms; impact of asthma on quality of life; perception of asthma control; exacerbations; and treatment/medication. RESULTS: Of the 400 patients interviewed, 272 (68%) were female. In relation to respiratory symptoms, the proportion of women reporting extremely bothersome symptoms (cough with sputum, tightness in the chest, cough/shortness of breath/tightness in the chest during exercise, nocturnal shortness of breath, and nocturnal cough) was greater than was that of men. Daytime symptoms, such as cough, shortness of breath, wheezing, and tightness in the chest, were more common among women than among men. Women also more often reported that their asthma interfered with normal physical exertion, social activities, sleep, and life in general. Regarding the impact of asthma on quality of life, the proportion of subjects who reported that asthma caused them to feel that they had no control over their lives and affected the way that they felt about themselves was also greater among women than among men. CONCLUSIONS: Among women, asthma tends to be more symptomatic, as well as having a more pronounced effect on activities of daily living and on quality of life. OBJETIVO: Avaliar o impacto da asma em relação ao sexo em uma amostra populacional de pacientes asmáticos no Brasil. MÉTODOS: Foram entrevistados pessoalmente 400 pacientes asmáticos com idade > 12 anos de uma amostra probabilística nacional por contato telefônico nas cidades de São Paulo, Rio de Janeiro, Curitiba e Salvador. Os indivíduos responderam um questionário de 53 questões relacionadas com cinco domínios da asma: sintomas; impacto da asma na vida; percepção do controle da asma; exacerbações; tratamento e medicação. RESULTADOS: Dos 400 pacientes entrevistados, 272 (68%) eram do sexo feminino. Em relação aos sintomas respiratórios, uma maior proporção de mulheres relatou se sentir extremamente incomodada com seus sintomas (tosse com secreção, sensação de aperto no peito, tosse/falta de ar/sensação de aperto no peito durante exercícios, falta de ar noturna e tosse noturna) do que os homens. Sintomas diurnos, como tosse, falta de ar, chiado e sensação de aperto no peito, foram mais comuns nas mulheres que nos homens. Além disso, a asma interferiu mais frequentemente nos esforços físicos normais, atividades sociais, durante o sono e na vida em geral nas mulheres. Sobre o impacto da asma na qualidade de vida, as mulheres relataram mais frequentemente que os homens que a asma causava uma sensação de falta de controle sobre a própria vida e que eram afetadas na forma como se sentiam em relação a si mesmas. CONCLUSÕES: As mulheres asmáticas apresentam mais sintomas e são mais afetadas em suas atividades diárias e qualidade de vida.

The aim of this study was to develop an efficient, low-cost, home-based pulmonary rehabilitation program and to evaluate the impact of the program on exercise as measured by the 6-min walk test (6MWT) and treadmill endurance test.Twenty-nine subjects with COPD (FEV1 = 62.4 ± 10.7% of predicted, 62.4 ± 10.7 y old) were included in a randomized and prospective pulmonary rehabilitation program, and they performed 24 sessions, 5 d/week. The control group included 15 subjects (FEV1 = 54 ± 26.2% of predicted, 65.3 ± 8 y old). They were evaluated pre-intervention and post-intervention by the 6MWT, St George Respiratory Questionnaire (SGRQ), treadmill endurance test, and spirometry. The home-based pulmonary rehabilitation program consisted of walking for 40 min along a corridor or a street, climbing stairs for 15 min, and exercising the arms with an oil can (1 kg) using diagonal movements for 15 min. Subjects were called once each week for encouragement and verification of adherence. Both groups received the usual pharmacologic treatment; in addition, the control group received a telephone call without guidance on exercise.The 2 groups were similar regarding age, FEV1, and FVC. The home-based pulmonary rehabilitation group increased by 65 m in the 6MWT (P.05) and 316.6 ± 81.8 m in the endurance test (P.05) and decreased by4 units in all SGRQ domains. The control group showed no difference in any variable.This study demonstrates that a simple, low-cost, home-based pulmonary rehabilitation program adapted to real-life situations leads to improvement in exercise capacity and quality of life.

OBJETIVO:Determinar a taxa de subdiagnóstico em novos casos de DPOC em uma amostra de pacientes após nove anos de seguimento do estudo Projeto Latino-Americano de Investigação em Obstrução Pulmonar (PLATINO) e compará-la à taxa de subdiagnóstico obtida na fase inicial do estudo, assim como identificar as características clínicas dos indivíduos subdiagnosticados na fase de seguimento.MÉTODOS:A população desse estudo foi composta por 1.000 residentes na cidade de São Paulo que fizeram parte do estudo PLATINO. Desses, 613 indivíduos participaram da fase de seguimento. Os indivíduos foram avaliados utilizando-se os mesmos instrumentos e equipamentos na fase inicial do estudo. O teste do qui-quadrado ou o teste t para amostras independentes foi utilizado para analisar a taxa de subdiagnóstico e identificar as características dos indivíduos subdiagnosticados durante a fase de seguimento.RESULTADOS:A taxa de subdiagnóstico para novos casos da DPOC após nove anos de acompanhamento foi de 70,0%. A taxa de subdiagnóstico na fase de seguimento foi 17,5% menor que a da fase inicial do estudo. Os indivíduos subdiagnosticados na fase de seguimento apresentavam poucos sintomas respiratórios, função pulmonar mais preservada e menor gravidade da doença do que aqueles previamente diagnosticados com DPOC.CONCLUSÕES:A taxa de subdiagnóstico na fase de seguimento foi menor que a da fase inicial do estudo. Os indivíduos subdiagnosticados na fase de seguimento do estudo PLATINO apresentavam o mesmo perfil clínico daqueles subdiagnosticados na fase inicial. Esses achados reforçam a necessidade da utilização da espirometria para o diagnóstico de DPOC e possibilitar a intervenção precoce. OBJECTIVE:To determine the underdiagnosis rate in new COPD cases at the end of a nine-year follow-up period-in the study designated Projeto Latino-Americano de Investigação em Obstrução Pulmonar (PLATINO, Latin-American Pulmonary Obstruction Investigation Project)-and compare that with the underdiagnosis rate during the initial phase of the study, as well as to identify the clinical features exhibited by the subjects who were not diagnosed until the end of the follow-up phase.METHODS:The study population comprised the 1,000 residents of the city of São Paulo, Brazil, who took part in the PLATINO study. Of those, 613 participated in the follow-up phase, during which the subjects were assessed with the same instruments and equipment employed in the initial phase of the study. We used the chi-square test or the independent sample t-test to analyze the underdiagnosis rate and to identify the characteristics of the subjects who were not diagnosed until the end of the follow-up phase.RESULTS:The underdiagnosis rate for new COPD cases at the end of the nine-year follow-up period was 70.0%. The underdiagnosis rate during the follow-up phase was 17.5% lower than that reported for the initial phase of the study. The subjects who were not diagnosed until the end of the follow-up phase presented with fewer respiratory symptoms, better pulmonary function, and less severe disease than did those previously diagnosed with COPD.CONCLUSIONS:The underdiagnosis rate for new COPD cases was lower in the follow-up phase of the study than in the initial phase. The subjects who were not diagnosed until the end of the follow-up phase of the PLATINO study presented with the same clinical profile as did those who were not diagnosed in the initial phase. These findings underscore the need for spirometry in order to confirm the diagnosis of COPD and provide early intervention.

BACKGROUND: Extubation failure is defined as the re-institution of respiratory support ranging from 24 to 72 hours following scheduled extubation and occurs in 2% to 25% of extubated patients. The aim of this study was to determine clinical and surgical risk factors that may predict extubation failure in patients submitted to non-emergency intracranial surgery. METHODS: This was a prospective observational cohort study. The study was carried out on 317 subjects submitted to nonemergency intracranial surgery for tumors, aneurysms, and arteriovenous malformation. Preoperative assessment was performed and subjects were followed up for the determination of extubation failure until either discharge from hospital or death. RESULTS: Twenty-six (8.2%) of the 317 subjects experienced extubation failure following surgery. The following variables were considered for the multivariate analysis: level of consciousness at the time of extubation, duration of mechanical ventilation prior to extubation, sex and the use of intraoperative mannitol. The multivariate analysis determined that the most important variable for extubation failure was the level of consciousness at the time of extubation (P .001), followed by female sex, which also showed to be significant (P .006). CONCLUSIONS: Lower level of consciousness (GCS 8T-10T) and female sex were considered risk factors for extubation failure in subjects submitted to elective intracranial

The aim of the present work was to compare the effectiveness of the vibrocompression and tapotage technique associatedwith postural draining and the tracheal aspiration technique in nurslings hospitalized due to bronchiolitis. Children below 2 years of ageadmitted at the hospital and in the emergency unit were the research subjects, all with a diagnosis of viral bronquiolitis in spontaneousbreathing in a total of 19 nurslings with clinical and radiological diagnosis of bronquiolitis. For this, the following interventions werecarried through: three groups were randomized: vibrocompression + postural draining (VC+DP); tapotage + postural draining (TAP+DP);and tracheal aspiration (ASP). Saturation of oxygen pulse (SpO2), cardiac frequency (FC), respiratory frequency (f), Silverman – AndersonScore (BSA), which evaluates the respiratory discomfort, were evaluated at three moments: pre-treatment (pre), post-immediate (post i)and 15 minutes after finishing the treatment (post 15); the amount of inhaled secretion was evaluated only in after i. Results show thata significant reduction in BSA and a greater amount of secretion was removed in VC+ DP and TAP + DP groups in post 15 (p < 0.05).There was reduction in FC in post 15 in the three groups. We conclude that VC and TAP, associated to postural draining, were efficientin the removal of secretion and the reduction of respiratory discomfort in nurslings with bronchiolitis.

Introduction: Quality of life (QoL) evaluation is an important tool to understand COPD patients well-being and to adequately treat them. However there is no follow up study of QoL in a populational based sample. Objectives: to evaluate the QoL of individuals at Basal and Follow up (FU) of PLATINO Study, 6 to 9 years later, of 3 cities of Latin America (Sao Paulo, Montevideo, Santiago). Methods: All individuals performed a pre and post bronchodilator spirometry and answered the SF-12 QoL questionnaire at their homes. Results: The following percentage of individuals were contacted at the FU: Sao Paulo, 60.7% of Basal, Montevideo, 72.6% and Santiago, 75.7%. The mental domain (MCS) improved in Montevideo and Santiago (p=0.001) and did not change in Sao Paulo; the physical domain (PCS) worsened in Sao Paulo and Montevideo (p=0.001) but kept stable in Santiago. However, most individuals with score under 50 for both PCS and MCS showed a tendency to improve, while the ones with score ≥ 50 tended to keep stable or worsen. The COPD patients in Sao Paulo and Santiago had a low PCS ( Conclusion: Our results show that the PLATINO population tended to worsen the PCS and improve the MSC with no relation to gender. The COPD population showed the same results and there was no relation to disease severity.

Introduction: Not much is known about the contribution of upper limbs mass for the total muscle mass in COPD patients. Objectives: To identify the distribution of muscle mass in both upper (UL) and lower limbs (LL) of patients with COPD by dual energy X-ray absorptiometry (DXA)and correlate muscular strength with lean mass index (LMM). Methods: We evaluated 96 patients with COPD and 85 healthy elderly control group-CG, matched for age and sex. Lung function, body composition by DXA and muscle strength of UL and LL were measured. Results: Mean age of COPD was 66.8 (±9.3) and of CG 64.2 (±8.9) years (p=0.064), with a BMI of 27.2 (±5.1) and 29.4 (±4.5) kg/m 2 , respectively (p = 0.002). There was no difference in LMM between the two groups but fat mass was higher in CG in both UL and LL and trunk (p 2 for men and ≥ 5.45 kg/m 2 for women) was lower in men with COPD (7.8 kg/m 2 ±1.1) than in CG (8.4 kg/m 2 ±0.9) (p > 0.05); and was lower in the severe and more severe than in the milder and moderate COPD patients (7.5 vs 8.0 kg/m 2 for men and 6.1 vs 6.8 kg/m 2 for women, respectively). There was an association between LMM of the UL (r = 0.5) and LL (r = 0.6) with muscle strength. The specific UL strength for COPD was lower (0.012 ± 0.003 kgf/g of muscle)than for CG (0.013 ± 0.004 kgf/g of muscle) (p Conclusions: LMM and ALMI are decreased in patients with COPD as assessed by DXA, and the muscle loss increases with advancing disease. Specific muscle strength is reduced in UL of patients with COPD sarcopenic may exist in a low percentage in COPD patients.

CONTEXT AND OBJECTIVE: Studies have shown that physiopathological changes to the respiratory system can occur following thoracic and abdominal surgery. Laminectomy is considered to be a peripheral surgical procedure, but it is possible that thoracic spinal surgery exerts a greater influence on lung function. The aim of this study was to evaluate the pulmonary volumes and maximum respiratory pressures of patients undergoing cervical, thoracic or lumbar spinal surgery. DESIGN AND SETTING: Prospective study in a tertiary-level university hospital. METHODS: Sixty-three patients undergoing laminectomy due to diagnoses of tumors or herniated discs were evaluated. Vital capacity, tidal volume, minute ventilation and maximum respiratory pressures were evaluated preoperatively and on the first and second postoperative days. Possible associations between the respiratory variables and the duration of the operation, surgical diagnosis and smoking status were investigated. RESULTS: Vital capacity and maximum inspiratory pressure presented reductions on the first postoperative day (20.9% and 91.6%, respectively) for thoracic surgery (P = 0.01), and maximum expiratory pressure showed reductions on the first postoperative day in cervical surgery patients (15.3%; P = 0.004). The incidence of pulmonary complications was 3.6%. CONCLUSIONS: There were reductions in vital capacity and maximum respiratory pressures during the postoperative period in patients undergoing laminectomy. Surgery in the thoracic region was associated with greater reductions in vital capacity and maximum inspiratory pressure, compared with cervical and lumbar surgery. Thus, surgical manipulation of the thoracic region appears to have more influence on pulmonary function and respiratory muscle action. CONTEXTO E OBJETIVO: Estudos têm demonstrado que alterações fisiopatológicas no sistema respiratório podem ocorrer após cirurgia torácica e abdominal. A laminectomia é considerada uma cirurgia periférica, mas é possível que as cirurgias de coluna torácica exerçam maior influência sobre a função pulmonar. O objetivo do estudo foi avaliar os volumes pulmonares e as pressões respiratórias máximas em pacientes submetidos a cirurgia de coluna cervical, torácica ou lombar. TIPO DE ESTUDO E LOCAL: Estudo prospectivo em hospital universitário terciário. MÉTODOS: Sessenta e três pacientes submetidos a laminectomia com diagnóstico tumor ou hérnia de disco foram avaliados. Foram avaliados, no pré-operatório, no primeiro e no segundo dias de pós-operatório, capacidade vital, volume corrente, volume por minuto e pressões respiratórias máximas. Possíveis associações entre as variáveis respiratórias e duração da cirurgia, diagnóstico cirúrgico e tabagismo foram investigadas. RESULTADOS: A capacidade vital e a pressão inspiratória máxima apresentaram redução no primeiro dia de pós-operatório (20.9% and 91.6%, respectivamente) nas cirurgias torácicas; P = 0,01), e a pressão expiratória máxima apresentou redução no primeiro dia de pós-operatório de cirurgia cervical (15.3%; P = 0,004). A incidência de complicações pulmonares foi de 3,6%. CONCLUSÕES: Houve redução da capacidade vital e das pressões respiratórias máximas no período pós-operatório em pacientes submetidos a laminectomia. A cirurgia na região torácica apresentou associação com maiores reduções na capacidade vital e na pressão inspiratória máxima em comparação com a cirurgia cervical e lombar. Assim, a manipulação cirúrgica da região torácica parece ter maior influência na função pulmonar e na ação dos músculos respiratórios.

OBJECTIVE: To evaluate the impact of asthma on activities of daily living and on health status in patients with controlled, partially controlled, or uncontrolled asthma in Brazil. METHODS: We used data related to 400 patients in four Brazilian cities (São Paulo, Rio de Janeiro, Salvador, and Curitiba), obtained in a survey conducted throughout Latin America in 2011. All study subjects were > 12 years of age and completed a standardized questionnaire in face-to-face interviews. The questions addressed asthma control, hospitalizations, emergency room visits, and school/work absenteeism, as well as the impact of asthma on the quality of life, sleep, and leisure. The level of asthma control was determined in accordance with the Global Initiative for Asthma criteria. RESULTS: Among the 400 respondents, asthma was controlled in 37 (9.3%), partially controlled in 226 (56.5%), and uncontrolled in 137 (34.2%). The numbers of patients with uncontrolled or partially controlled asthma who visited the emergency room, who were hospitalized, and who missed school/work were higher than were those of patients with controlled asthma (p = 0.001, p = 0.05, and p = 0.01, respectively). Among those with uncontrolled asthma, the impact of the disease on activities of daily living, sleep, social activities, and normal physical exertion was greater than it was among those with controlled or partially controlled asthma (p < 0.001). CONCLUSIONS: In Brazil, asthma treatment should be monitored more closely in order to increase treatment adherence and, consequently, the level of asthma control, which can improve patient quality of life and minimize the negative impact of the disease. OBJETIVO: Avaliar o impacto da asma nas atividades da vida diária e na saúde em pacientes com asma controlada, parcialmente controlada ou não controlada no Brasil. MÉTODOS: Foram utilizados dados de 400 pacientes de quatro cidades brasileiras (São Paulo, Rio de Janeiro, Curitiba e Salvador) obtidos em um inquérito realizado em países da América Latina em 2011. Todos os indivíduos do estudo tinham idade > 12 anos e responderam a um questionário padronizado por meio de entrevista presencial. As questões abordavam o controle da asma, número de hospitalizações, de consultas de urgência, absenteísmo na escola/trabalho e impacto da asma na qualidade de vida, sono e lazer. O nível de controle da asma foi verificado segundo os critérios da Global Initiative for Asthma. RESULTADOS: Entre 400 entrevistados, a asma estava controlada em 37 (9,3%); parcialmente controlada, em 226 (56,5%); e não controlada, em 137 (34,2%). O número de pacientes com asma não controlada ou parcialmente controlada que apresentaram hospitalizações, visitas ao pronto-socorro e faltas na escola/trabalho foi maior do que o daqueles com asma controlada (p = 0,001, p = 0,05 e p = 0,01, respectivamente). Os participantes com asma não controlada apresentaram um maior impacto da doença em atividades da vida diária, sono, atividades sociais e esforço físico normal do que aqueles com asma parcialmente controlada ou controlada (p < 0,001). CONCLUSÕES: Medidas terapêuticas devem ser mais intensamente adotadas em nosso país para melhorar o controle da asma e estimular a aderência ao tratamento. Isso, seguramente, proporcionará uma melhor qualidade de vida aos pacientes e uma redução do impacto negativo da doença.

Objective A survey of intensive care units (ICU) in Sao Paulo that care for patients with TBI and ICH using the hyperventilation technique. Methods A questionnaire was given to the physiotherapist coordinator at 57 hospitals in Sao Paulo, where 24-h neurosurgery service is provided. Results Fifty-one (89.5%) hospitals replied. From this total, thirty-four (66.7% perform the hyperventilation technique, 30 (85%) had the objective to reach values below 35 mmHg, four (11%) levels between 35 mmHg and 40 mmHg and one (3%) values over 40 mmHg. Conclusions We concluded that most hospitals in Sao Paulo perform hyperventilation in patients with severe brain trauma although there are not any specific Brazilian guidelines on this topic. Widespread controversy on the use of the hyperventilation technique in patients with severe brain trauma highlights the need for a specific Global policy on this topic.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Background: Patients with chronic obstructive pulmonary disease (COPD) have some limitations during activities of daily living that involve the arms. There is little information on the benefits of shoulder girdle training and its repercussions for activities of daily living in patients with COPD. the purpose of this study was to investigate whether shoulder girdle training with diagonal movements increases upper limb muscle strength and improves performance of activities of daily living in patients with COPD.Methods: Thirty-five patients with moderate to severe COPD (forced expiratory volume in one second 1.22 +/- 0.49 L) and aged 36-80 years were recruited. Endurance time, maximal sustained weight, oxygen saturation, heart rate, respiratory rate, dyspnea, and arm fatigue were evaluated during an incremental upper limb test and eight simulated activities of daily living before and after an 8-week exercise training program.Results: A significant gain was observed for upper limb strength (P < 0.05). At the peak of the upper limb incremental test, the respiratory rate dropped from 33 to 27 breaths per minute, the Borg dyspnea score decreased from 2 to 0.5, and the upper limb fatigue score decreased from 3 to 2 (P < 0.05). No change was seen in any of these parameters during performance of activities of daily living.Conclusion: Although shoulder girdle training increased upper limb strength, no improvement was detected in performance of activities of daily living.

CONTEXT AND OBJECTIVE There are no reports on reintubation incidence and its causes and consequences during the postoperative period following elective intracranial surgery. The objective here was to evaluate the incidence of reintubation and its causes and complications in this situation. DESIGN AND SETTING Prospective cohort study, using data obtained at a tertiary university hospital between 2003 and 2006. METHODS 169 patients who underwent elective intracranial surgery were studied. Preoperative assessment was performed and the patients were followed up until hospital discharge or death. The rate of reintubation with its causes and complications was ascertained. RESULTS The incidence of reintubation was 12.4%, and the principal cause was lowered level of consciousness (71.5%). There was greater incidence of reintubation among females (P = 0.028), and greater occurrence of altered level of consciousness at the time of extubation (P < 0.0001). Reintubated patients presented longer duration of mechanical ventilation (P < 0.0001), longer stays in the intensive care unit (ICU) and in the hospital (P < 0.0001), greater incidence of pulmonary complications (P < 0.0001), greater need for reoperation and tracheostomy, and higher mortality (P < 0.0001). CONCLUSION The incidence of reintubation in these patients was 12.4%. The main cause was lowering of the level of consciousness. Female gender and altered level of consciousness at the time of extubation correlated with higher incidence of reintubation. Reintubation was associated with pulmonary complications, longer durations of mechanical ventilation, hospitalization and stay in the ICU, greater incidence of tracheostomy and mortality. CONTEXTO E OBJETIVO Não há relatos sobre incidência de reintubação, suas causas e consequências no pós-operatório de cirurgia intracraniana eletiva. O objetivo foi avaliar a incidência de reintubação, suas causas e complicações em pós-operatório de cirurgia intracraniana eletiva. TIPO DE ESTUDO E LOCAL Estudo de coorte prospectivo, com dados que foram obtidos de 2003 a 2006 em um hospital universitário terciário. MÉTODO 169 pacientes submetidos a cirurgia intracraniana eletiva foram estudados. Foi realizada avaliação pré-operatória e os pacientes foram acompanhados até a alta hospitalar ou óbito, verificando a taxa de reintubação, suas causas e complicações. RESULTADOS A incidência de reintubação foi de 12,4% sendo a principal causa o rebaixamento do nível de consciência (71,5%). Houve maior incidência de reintubação no sexo feminino (P = 0,028), bem como do nível de consciência alterado no momento da extubação (P < 0,0001). Pacientes reintubados apresentaram maior tempo de ventilação mecânica (P < 0,0001) e de internação em unidade de terapia intensiva (UTI) e hospitalar (P < 0,0001), maior incidência de complicações pulmonares (P < 0,0001), maior necessidade de reoperação e traqueostomia, além de aumento de mortalidade (P < 0,0001). CONCLUSÃO A incidência de reintubação nesses pacientes foi de 12,4%. A principal causa da reintubação foi o rebaixamento do nível de consciência. O sexo feminino e nível de consciência alterado no momento da extubação foram relacionados à maior incidência de reintubação. A reintubação foi associada a complicações pulmonares, maior tempo de ventilação mecânica, de internação e de permanência na UTI, maior incidência de traqueostomia e mortalidade.

To correlate quality of life (QoL) and physical limitations in histological proven primary brain tumor patients using a battery of generic, disease-specific and symptom questionnaires.Thirty patients with primary brain tumors were selected from a neuro-oncology outpatient clinic. The FACT-Br Functional Assessment of Cancer Therapy-Brain (specific quality of life questionnaire for patients with brain tumors), SF-36 (generic quality of life questionnaire), HADS (anxiety and depression), and Barthel Index (functionality scale) were answered by the patients at the same interview.The Barthel index did not demonstrate correlation with any subscale of the FACT-Br questionnaire. The HADS had a negative correlation with all FACT-Br subscales and its total score. The SF-36 had a significant weak to moderate correlation with the FACT-Br questionnaire.Considering that the FACT-Br is a quick specific questionnaire, it can be a valuable and simple option in evaluating QoL in brain tumor patients with good functional capacity.
