ABSTRACT

Introdução: a verificação da limitação ao fluxo aéreo ocasionado pelo tabagismo, por meio da mensuração do pico de fluxo expiratório, é uma medida viável para estudos populacionais que permite a sinalização precoce ou prevenção da instalação da doença pulmonar obstrutiva crônica. Objetivo: avaliar o grau de limitação ao fluxo expiratório em tabagistas em diferentes níveis de atividade física. Metodologia: trata-se de um estudo transversal. Foram selecionados 68 fumantes ativos por mais de um ano, acima de 18 anos, de ambos os sexos. O pico de fluxo expiratório foi obtido por meio do medidor portátil do modelo Mini-WrightTM e o nível de atividade física foi avaliado pelo International Physical Activity Questionnaire 8.0. As variáveis estudadas foram descritas pela amplitude de variação das médias, desvios padrão, máximo, mínimo e coeficiente de variação, sendo estabelecido o nível de significância de 5% através do teste Qui-quadrado. Resultados: o percentual de redução dos valores do pico de fluxo expiratório, previsto em relação ao obtido, chegou a uma redução média de 56,87% em maiores de 60 anos e 53,19% em tabagistas com um tempo de prática maior de 30 anos. Houve aumento considerável do percentual médio de redução do pico de fluxo expiratório nos grupos de tabagistas insuficientemente ativos e sedentários. Conclusão: os resultados sugerem que a limitação ao fluxo expiratório foi mais acentuada em tabagistas do sexo feminino, acima de 60 anos, com tempo superior a 30 anos de prática do tabagismo e com baixo nível de atividade física. Os tabagistas considerados muito ativos apresentaram menor nível de limitação ao fluxo expiratório.


Introduction: the verification of airflow limitation caused by smoking, through the Peak Expiratory Flow is a viable measure for population studies that allows the early signaling or prevention of the onset of Chronic Obstructive Pulmonary Disease. Objective: assess the degree of expiratory flow limitation in smokers at different levels of physical activity. Methods: this is a cross-sectional study. 68 active smokers for more than one year, over 18 years, of both sexes were selected. Peak expiratory flow was obtained using a portable Mini-WrightTM model and the level of physical activity was assessed using the International Physical Activity Questionnaire 8.0. The variables studied were described by the range of variation of the means, standard deviations, maximum, minimum and coefficient of variation, with a significance level of 5% being established using the Chi-square test. Results: the percentage of reduction in the values of peak expiratory flow, predicted in relation to that obtained, reached a mean reduction of 56.87% in people over 60 years of age and 53.19% in smokers with more than 30 years of practice. There was a considerable increase in the mean percentage of reduction in peak expiratory flow in the groups of insufficiently active and sedentary smokers. Conclusion: results suggest that expiratory flow limitation was more accentuated in female smokers, over 60 years of age, with more than 30 years of smoking practice and with a low level of physical activity. Smokers considered very active had a lower level of limitation of expiratory flow.

ABSTRACT

INTRODUÇÃO: O pico de fluxo expiratório (PFE) é comumente usado para monitorar a progressão de doenças respiratórias, pois fornece boas informações sobre o estado das vias aéreas. Uma boa quantidade de pesquisas está sendo feita em todo o mundo para estabelecer uma equação de previsão local. A força-tarefa conjunta da Sociedade Torácica Americana e da Sociedade Respiratória Europeia promoveu pesquisas a esse respeito. Na Índia, os dados derivados da população caucasiana ainda são usados para o PFE. OBJETIVO: Estudar a relação dos parâmetros do PFE e os dados antropométricos como idade, altura, peso, índice de massa corporal (IMC), área de superfície corporal (ASC) e estabelecer uma equação de regressão para jovens adultos indianos. MÉTODOS: PFE foi feito em 1000 sujeitos de 15-25 anos da região metropolitana de Mumbai. O coeficiente de correlação de Pearson foi usado para entender a relação dos parâmetros antropométricos e PFE. A análise de regressão multivariada foi feita para estabelecer uma equação de predição. (Alfa 5%) RESULTADOS: Idade e todos os parâmetros antropométricos foram correlacionados com PFE. O pico de fluxo expiratório médio da população masculina foi de 515 ml / seg, enquanto a feminina foi de 399 ml / seg. Para o PFE, a maior correlação foi observada com a ASC seguida de altura, peso e idade, enquanto o IMC apresentou o menor coeficiente de correlação. TPFE teve a melhor significância com a idade, ASC, altura e IMC. Teve menos significado com o peso. No sexo feminino, a TPFE teve a melhor significância com altura, peso, IMC e idade. CONCLUSÃO: Existem diferenças de gênero na TPFE. Portanto, equações específicas de gênero são necessárias para a estimativa da TPFE


INTRODUCTION: Peak expiratory flow rate (PEFR) is commonly used to monitor the progression of respiratory diseases as it gives good information about the status of airways. A good amount of research is going across the world to establish a local prediction equation. The joint task force of the American thoracic society and European Respiratory Society has promoted research in this regard. In India, data derived from the Caucasian population are still used for PEFR. OBJECTIVE: To verify the relationship between PEF levels and the variables age, sex, anthropometric and body surface area, and establish the regression equation for young Indian adults. METHODS: A cross-sectional observational study was conducted in 15-25 years aged 1000 subjects from the Metropolitan region of Mumbai. Pearson's correlation coefficient was used to understand the relation of anthropometric parameters and PEFR. Multivariate regression analysis was done for establishing a prediction equation (Alpha 5%). RESULTS: Age and all anthropometric parameters were correlated with PEFR. The mean PEFR of the male population was 515 ml/sec, whereas, for females, it was 399 ml/sec, for PEFR highest correlation was observed with BSA (.696) followed by weight (.667), height (.630), age (.504) whereas BMI shown lowest correlation coefficient (.445). PEFR had the best significance with age, BSA, Height, and BMI. It had less significance with weight. In females, PEFR had the best significance with Height, weight, BMI, and Age. CONCLUSION: Gender-wise differences exist in PEFR. Hence gender-specific equations are needed for the estimation of PEFR.

ABSTRACT

Peak expiratory flow (PEF) is a portable, reliable, and inexpensive method for lung function assessment. PEF can reflect expiratory airflow limitation and its variability can document reversibility, which provides an objective basis for the diagnosis of asthma in children. Short-term PEF monitoring can be an important aid in the management of acute asthma exacerbations, identification of possible triggers, and assessment of response to treatment. Long-term PEF monitoring can assist in the assessment of asthma control and warning of acute exacerbations, and this is useful for children with severe asthma. This article reviews the measurements, influencing factors, interpretation, and application of PEF, and its role in the diagnosis and management of asthma in children, to provide references for the clinical application of PEF in children.

ABSTRACT

Abstract Introduction: Obesity, characterized by the accumulation of excess body fat, can alter respiratory mechanics and compromise functional capacity. Given its increasing prevalence and the significant morbidity associated with the condition, it is important to investigate techniques that enable rapid, easy measurement of lung function and the possible correlation between obesity and functional capacity. Objective: To assess lung function and functional capacity in obese adults and determine whether there is a correlation between reduced peak expiratory flow and impaired functional capacity. Methods: 30 participants, distributed into two groups: obese (36 ± 13 years) and normal weight (31 ± 9 years) were evaluated based on anthropometric measurements, the six-minute walk test (6MWT) and peak expiratory flow (PEF). Results: The obese individuals showed reduced PEF (382 ± 99 vs. 497 ± 104 L/min, p < 0.01), walked shorter distances in the 6MWT (453 ± 37 vs. 617 ± 50 m, p < 0.01), had higher blood pressure and perceived exertion (p < 0.05) when compared to normal weight participants. Additionally, there was a positive significant association between expiratory flow and distance walked in the 6MWT (r = 0.635 and p < 0.001). Conclusion: Obese individuals exhibited lower PEF and walked shorter distances in the 6MWT, indicating a positive correlation between these two variables. In light of this outcome, the assessment methods used could contribute to improving analysis of respiratory and functional status in this population and aid in exercise prescription.


Resumo Introdução: A obesidade, caracterizada por acúmulo excessivo de tecido adiposo no organismo, pode alterar a mecânica ventilatória, trazendo prejuízos funcionais. Considerando a prevalência crescente da obesidade, bem como a grande morbidade associada a esta condição, torna-se relevante investigar técnicas de mensuração rápidas e fáceis da função ventilatória e a possível correlação com a capacidade funcional. Objetivo: Avaliar a função ventilatória e a capacidade funcional em adultos obesos e determinar se pico de fluxo expiratório reduzido está correlacionado com prejuízo da capacidade funcional. Métodos: 30 participantes, distribuídos em dois grupos: obeso (36 ± 13 anos) e eutrófico (31 ± 9 anos) foram avaliados por meio de medidas antropométricas, do teste de caminhada de seis minutos (TC6´) e da avaliação do pico de fluxo expiratório (PFE). Resultados: Os indivíduos obesos apresentaram reduzido PFE (382 ± 99 vs. 497 ± 104 L/min, p < 0,01) e percorreram menor distância no TC6´ (453 ± 37 vs. 617 ± 50 m, p < 0,01) com maior pressão arterial e percepção de esforço (p < 0,05) quando comparados aos eutróficos. Além disso, foi encontrada correlação positiva e significativa entre fluxo expiratório e distância percorrida (r = 0,635 e p < 0,001). Conclusão: Os indivíduos obesos tiveram menor PFE e menor distância percorrida no TC6´, constatada correlação positiva entre essas duas variáveis. Diante de tal desfecho, a inclusão dos métodos avaliativos utilizados podem contribuir para melhor análise da condição respiratória e funcional dessa população e auxiliar na prescrição de exercícios.

ABSTRACT

OBJECTIVE: To evaluate the relationship between respiratory muscle strength and grip strength in institutionalized and communitydwelling older adults. METHODS: This convenience sampled cross-sectional study had 64 voluntary participants with a good general health status and without limiting chronic diseases: 33 were institutionalized and 31 lived in the community. Maximal inspiratory pressure, maximal expiratory pressure, peak expiratory flow, grip strength, anthropometric data, and physical activity level were assessed. The data were subjected to descriptive analysis, Pearson's correlation test, and linear regression analysis. RESULTS: In the institutionalized group, there was no between respiratory variables and grip strength, but maximal expiratory pressure was the respiratory predictor most strongly associated with grip strength (p = 0.04). In the community-dwelling group, there was a correlation between maximal inspiratory pressure and grip strength (r = 0.54), maximal expiratory pressure and grip strength (r = 0.62), and peak expiratory flow and grip strength (r = 0.64); peak expiratory flow and maximal expiratory pressure were the respiratory predictors most strongly associated with grip strength (p < 0.05). In a joint group analysis, there was an association between maximal inspiratory pressure and grip strength (r = 0.40), maximal expiratory pressure and grip strength (r = 0.57), and peak expiratory flow and grip strength (r = 0.57); peak expiratory flow and maximal expiratory pressure were the respiratory predictors most strongly associated with grip strength (p < 0.05). CONCLUSIONS: Peak expiratory flow and maximal expiratory pressure seem to be good predictors of grip strength in community-dwelling older adults, but this relationship does not seem to be maintained in institutionalized patients, possibly because of a greater loss of respiratory function.


OBJETIVO: Avaliar a relação entre força muscular respiratória e força de preensão palmar em idosos institucionalizados e da comunidade. METODOLOGIA: Caracteriza-se por um estudo transversal com 64 voluntários, sendo 33 institucionalizados e 31 da comunidade. Avaliou-se a pressão inspiratória máxima, pressão expiratória máxima, pico de fluxo expiratório, força de preensão palmar, dados antropométricos e nível de atividade física.Os dados foram submetidos a uma análise descritiva, teste de correlação de Pearson e análise de regressão linear. RESULTADOS: No grupo de institucionalizados, não houve correlação entre as variáveis respiratórias e as de força de preensão palmar, porém o preditor respiratório mais fortemente associado à força de preensão palmar foi a pressão expiratória máxima (p = 0,04). No grupo da comunidade, verificou-se correlação entre pressão inspiratória máxima e força de preensão palmar (r = 0,54), pressão expiratória máxima e força de preensão palmar (r = 0,62), pico de fluxo expiratório e força de preensão palmar (r = 0,64), e o preditor respiratório mais fortemente associado à força de preensão palmar foi pico de fluxo expiratório e pressão expiratória máxima (p < 0,05). Na análise conjunta dos grupos, verificou-se associação entre pressão inspiratória máxima e força de preensão palmar (r = 0,40), pressão expiratória máxima e força de preensão palmar (r = 0,57), pico de fluxo expiratório e força de preensão palmar (r = 0,57), e o preditor respiratório mais fortemente associado à força de preensão palmar foi pico de fluxo expiratório e pressão expiratória máxima (p < 0,05). CONCLUSÕES: Em idosos da comunidade, o pico de fluxo expiratório e a pressão expiratória máxima parecem ser bons preditores da força de preensão palmar, enquanto, em institucionalizados, essa relação parece não se manter possivelmente por conta de maior acentuação de perda da função respiratória.

ABSTRACT

Introdução: a disfunção pulmonar no pós-operatório de cirurgia cardíaca continua sendo uma das mais importantes causas demorbidade, sendo que o comprometimento da função pulmonar, nessa circunstância, é frequente e contribui, significativamente, para o aumento do tempo de permanência hospitalar. O objetivo deste estudo foi avaliar o comportamento da função pulmonar em pacientes adultos hospitalizados, submetidos à cirurgia cardíaca por esternotomia mediana, no momento a alta da unidade tratamento intensivo, comparado ao quarto dia após a alta dessa unidade. Metodologia: o estudo foi realizado em uma unidade de pós-operatório de cirurgia cardiovascular, após aprovação do Comitê de Ética em Pesquisa. O Termo de Consentimento Livre Esclarecido foi obtido em todos os casos. Incluíram-se pacientes maiores de 18 anos, submetidos à cirurgia cardíaca eletiva. A função pulmonar foi realizada na alta da unidade de tratamento intensivo e, posteriormente, repetida no quarto dia. A função pulmonar foi mensurada pela capacidade vital forçada, pico de fluxo expiratório, além de variáveis do exame físico, como frequência respiratória e ausculta pulmonar. Resultados: 94 pacientes foram submetidos à cirurgia cardíaca eletiva via esternotomia mediana. A média (desvio padrão) de idade foi 50,64 (16,53) anos, com predomínio do sexo masculino (52,1%). A mediana (Q1-Q3) do tempo de permanência na unidade de tratamento intensivo foi de 2,00 dias (2,00-3,00), ao passo que a mediana (Q1-Q3) do tempo de permanência hospitalar foi de 6,00 dias (5,00-8,00). A mediana (Q1-Q3) da capacidade vital forçada e do fluxo respiratório, obtida pela espirometria no pós-operatório, no momento da alta, foi significativamente menor quando comparada ao quarto dia após alta da unidade de tratamento intensivo (p< 0,01). O tempo de permanência na unidade, assim como o tempo de permanência hospitalar não impactou na evolução das variáveis de função pulmonar. Conclusão: a função pulmonar é potencialmente reduzida no período inicial após a cirurgia cardíaca, com evolução gradual, e de recuperação lenta, no curso da recuperação cirúrgica. A manutenção desses valores reduzidos a níveis não críticos por um período prolongado no pós-operatório parece não afetar o desempenho dos pacientes, no que tange a capacidade de respirar profundamente e na efetividade de tosse.


Introduction: pulmonary dysfunction in the postoperative period of cardiac surgery continues to be one of the most important causes of morbidity, and the involvement of pulmonary function in this circumstance is frequent and contributes significantly to an increase in the length of hospital stay. Objective: the objective of this study was to evaluate the pulmonary function behavior in hospitalized adult patients submitted to cardiac surgery by median sternotomy at the time of discharge from the intensive care unit, compared to the fourth day after discharge from this unit. Metodology: the study was performed in a postoperative unit of cardiovascular surgery, after approval of the Research Ethics Committee. The Informed Consent Form was obtained in all cases. Patients older than 18 years who underwent elective cardiac surgery were included. Pulmonary function was performed on discharge from the intensive care unit and then repeated on the fourth day. Pulmonary function was measured by forced vital capacity, peak expiratory flow, besides variables of physical examination, such as respiratory rate and pulmonary auscultation. Results: a number of 94 patients underwent elective cardiac surgery via median sternotomy. Mean (standard deviation) of age was 50.64 (16.53) years, with a predominance of males (52.1%). Median (Q1-Q3) of the time spent in the intensive care unit was 2.00 days (2.00-3.00), while the median (Q1-Q3) of the length of hospital stay was 6.00 days (5.00-8.00). Median (Q1-Q3) of forced vital capacity and respiratory flow, obtained by spirometry in the postoperative period at discharge, was significantly lower when compared to the fourth day after discharge from the intensive care unit (p <0.01 ). The length of stay in the unit, as well as the length of hospital stay, did not affect the evolution of pulmonary function variables. Conclusion: pulmonary function is potentially reduced in the initial period after cardiac surgery, with gradual evolution, and slowness in the course of surgical recovery. Maintaining these reduced values at uncritical levels for a prolonged postoperative period does not appear to affect patients' performance with regard to their ability to breathe deeply and in cough effectiveness.

ABSTRACT

Objetivo: avaliar a prevalência dos sintomas respiratórios ocupacionais, pico de fluxo expiratório (PFE) e fatores associados em trabalhadores de uma indústria de cerâmica do sul do Brasil. Métodos: estudo transversal. Foram avaliados trabalhadores de uma indústria de cerâmica do Sul do Brasil. Como instrumentos de pesquisa, foram aplicados questionários relacionados a aspectos ocupacionais, sintomas respiratórios, hábitos tabágicos e medida do PFE. As variáveis sociodemográficas e ocupacionais foram comparadas com os sintomas respiratórios e PFE. Resultados: foram avaliados 151 trabalhadores, sendo, predominantemente, do sexo masculino (87,4%), com média (±DP) de idade de 30,4 (±8,4) anos e histórico de tabagismo em 23,8% dos participantes. Entre os sintomas respiratórios, 23% relataram tosse diária e noturna e dispneia, 21% confirmaram escarro durante o dia/noite, e apenas 7% referiram chiado ou sibilos. O PFE abaixo de 80% do previsto foi encontrado em 37,1% dos trabalhadores, com média (±DP) de 84(±16,7)%. Ao comparar os fatores ocupacionais com os desfechos, foi observado que o menor tempo de trabalho esteve relacionado à maior prevalência de tosse (p=0,024). Conclusão: os sintomas respiratórios mais prevalentes foram a tosse e a dispneia, seguidos por escarro e sibilância. Aproximadamente, 1/3 dos trabalhadores demonstraram PFE<80%. Contudo, a relação inversa entre tempo de trabalho e sintomas merece maior investigação.


Objective: To evaluate the prevalence of occupational respiratory symptoms, peak expiratory flow (PEF) and associated factors in workers from a ceramic industry in southern Brazil. Methods: Cross-sectional study. Workers from a ceramic industry in southern Brazil were evaluated. The research instruments were questionnaires related to occupational aspects, respiratory symptoms, smoking habits, and PEF measurements. Sociodemographic and occupational variables were compared with respiratory symptoms and PEF. Results: We evaluated 151 workers, predominantly male (87.4%), with a mean (±DP) age of 30.4 (±8.4) years and a history of smoking in 23.8% of participants. Among the respiratory symptoms, 23% reported daily and nocturnal cough and dyspnea, 21% confirmed sputum during the day / night, and only 7% reported wheezing. PEF below 80% of predicted was found in 37.1% of workers, with a mean (± DP) of 84 (± 16.7) %. When comparing the occupational factors with outcomes, it was observed that the shorter working time was related to higher cough prevalence (p=0.024). Conclusion: The most prevalent respiratory symptoms were coughing and dyspnea, followed by sputum and wheezing. Approximately 1/3 of workers showed PEF <80%. However, the inverse relationship between working time and symptoms merits further investigation.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients.MATERIALS AND METHODS: This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), peak expiratory flow rate (PEFR), and ratio of FEV₁ to FVC (FEV₁/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern.RESULTS: Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17–63 years). The mean FVC, FEV₁, FEV₁/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns.CONCLUSION: Isolated mandibular fractures presented with abnormal pulmonary function pattern.

Introduction: Patients undergoing abdominal surgery have a risk of pulmonary complications in the postoperative period, such as: decreased respiratory activity, altered ventilation / perfusion ratio, and increased respiratory muscle work, increasing hospital morbidity and mortality. Objective: To evaluate the impact of positive expiratory pressure on lung function in postoperative patients of elective abdominal surgeries. Methods: Characterized as an exploratory study of the type randomized clinical trial, composed of 40 patients randomized into two groups, the intervention group was submitted to a protocol of positive expiratory pressure in the respiratory tract with final expiratory positive pressure of 10 cmH2O and ambulation for 150 meters and the control group underwent walking for 150 meters and guidelines on the importance of deep inspiration every two hours, being evaluated in the immediate postoperative period and at the time of hospital discharge. Results: A homogeneous pattern could be observed between the groups studied. Statistical significance was observed in the intra-group analysis in the variables peripheral oxygen saturation (p <0.0001) and peak expiratory flow (p = 0.009) vital forcing (p <0.0001). In the analysis between groups, a statistical difference was observed in peripheral oxygen saturation (p = 0.010) and peak expiratory flow (p = 0.012). Conclusion: We concluded that the use of positive expiratory pressure in the postoperative period of abdominal surgeries had a positive impact on peripheral oxygen saturation and peak expiratory flow, demonstrating a significant benefit in the ventilatory and diffusional process in the studied group.

ABSTRACT

Abstract Introduction: Although the nose and lungs are separate organs, numerous studies have reported that the entire respiratory system can be considered as a single anatomical and functional unit. The upper and lower airways affect each other either directly or through reflex mechanisms. Objective: In this study, we aimed to evaluate the effects of the radiofrequency ablation of persistent inferior turbinate hypertrophy on nasal and pulmonary function. Methods: Twenty-seven patients with bilateral persistent inferior turbinate hypertrophy without septal deviation were included in this study. All of the patients were evaluated using anterior rhinoscopy, nasal endoscopy, acoustic rhinometry, a visual analogue scale, and flow-sensitive spirometry on the day before and 4 months after the radiofrequency ablation procedure. Results: The post-ablation measurements revealed that the inferior turbinate ablation caused an increase in the mean cross-sectional area and volume of the nose, as well as in the forced expiratory volume in 1 s, forced vital capacity, and peak expiratory flow of the patients. These differences between the pre- and post-ablation results were statistically significant. The post-ablation visual analogue scale scores were lower when compared with the pre-ablation scores, and this difference was also statistically significant. Conclusion: This study demonstrated that the widening of the nasal passage after the reduction of the inferior turbinate size had a favorable effect on the pulmonary function tests.


Resumo Introdução: Embora o nariz e os pulmões sejam órgãos separados, numerosos estudos relataram que todo o sistema respiratório pode ser considerado como uma única unidade anatômica e funcional. As vias aéreas superiores e inferiores afetam uma à outra diretamente ou através de mecanismos reflexos. Objetivo: Avaliar os efeitos da ablação por radiofrequência em conchas nasais inferiores com hipertrofia persistente sobre a função nasal e pulmonar. Método: Foram incluídos neste estudo 27 pacientes com hipertrofia persistente bilateral de conchas inferiores sem desvio septal. Todos os pacientes foram avaliados com rinoscopia anterior, endoscopia nasal, rinometria acústica, escala visual analógica e espirometria sensível ao fluxo no dia anterior e quatro meses após o procedimento de ablação por radiofrequência. Resultados: As medidas pós-ablação demonstraram que a ablação das conchas nasais inferiores resultou em um aumento da área transversal média e do volume do nariz, bem como do volume expiratório forçado em um segundo, da capacidade vital forçada e do fluxo expiratório máximo dos pacientes. Essas diferenças entre os resultados pré e pós-ablação foram estatisticamente significantes. Os escores da escala visual analógica pós-ablação foram menores quando comparados com os escores pré-ablação e essa diferença também foi estatisticamente significante. Conclusão: O alargamento da passagem nasal após a redução do tamanho das conchas nasais inferiores teve efeito favorável nos testes de função pulmonar.

ABSTRACT

BACKGROUND: Despite growing concern over occupational exposure to particulate matter (PM) such as grain dust and diesel exhaust, information about the exposure level and health implications among workers in small-scale milling enterprises in developing countries like Nigeria has not been adequately documented. The purpose of this study was to assess the level of exposure to grain dust and diesel exhaust and effect on lung function among grain millers in food markets in Ibadan metropolis, Nigeria. METHODS: The study adopted descriptive cross-sectional design with a comparative approach. Sixteen grain milling shops each were randomly selected from two major food markets in Ibadan metropolis for indoor PM₁₀ and PM(2.5) monitoring. Seventy-two respondents each were proportionately selected from grain millers and shop owners for forced expiratory volume in one second and peak expiratory flow rate tests. RESULTS: The PM(2.5) concentrations for both market locations ranged between 1,269.3 and 651.7 μg/m³, while PM₁₀ concentrations were between 1,048.2 and 818.1 μg/m³. The recorded concentrations exceeded the World Health Organization guideline limit of 50 μg/m³ and 25 μg/m³ for PM(2.5) and PM₁₀, respectively. As compared with control group (2.1 L), significantly lower forced expiratory volume in one second value (1.61 L) was observed among the exposed group (p < 0.05). Likewise, significantly lower peak expiratory flow rate value (186.7 L/min) was recorded among the exposed group than the control group (269.51 L/min) (p < 0.05). CONCLUSION: Exposure to grain dust and diesel exhaust accentuated respiratory disorders with declines in lung functions amongst grain millers. Improved milling practices and engaging cleaner milling facilities should be adopted to minimize exposure and related hazards.

ABSTRACT

OBJECTIVE: The head-tilt/chin-lift (HT/CL) is a simple, routinely used maneuver to open the upper airway. Changes in the peak expiratory flow rate (PEFR) before and after the HT/CL maneuver have not been evaluated among conscious volunteers who are regarded as a control cohort.METHODS: Sixty healthy 20-year-old volunteers (30 males and 30 females) were enrolled. The supine position was defined as the position at which the ear-eye line was at a 10° angle to the horizontal. The HT/CL position was defined as the position at which the ear-eye line was at a 25° angle to the horizontal. PEFR was measured using a hand-held device with the subject in the supine position (pre-PEFR) and HT/CL position (post-PEFR), respectively. One set was defined as these two measurements. Five sets of measurements were performed on each subject (300 sets). The set with the maximal and minimal difference between pre-PEFR and post-PEFR were excluded from the analysis. We used a paired t-test to compare the mean pre-PEFR and post-PEFR values for the entire group and subgroups divided by sex, height, body weight, body mass index and response status.RESULTS: Overall, 360 measurements (180 sets) were analyzed. The mean pre-PEFR and post-PEFR were 316.1±87.6 and 346.5±94.7 L/min, respectively. Further, significant differences were observed for sex, height, body weight, and body mass index. In 10 subjects, post-PEFR was lower than pre-PEFR.CONCLUSION: PEFR increased by 9.6% after the HT/CL maneuver in young conscious subjects, but some subjects showed decreased PEFR after the HT/CL maneuver.

ABSTRACT

ABSTRACT Objective: To determine the frequency of spirometry in elderly people, by age group, at a pulmonary function clinic, to assess the quality of spirometry in the extremely elderly, and to determine whether chronological age influences the quality of spirometry. Methods: This was a cross-sectional retrospective study evaluating information (spirometry findings and respiratory questionnaire results) obtained from the database of a pulmonary function clinic in the city of Aracaju, Brazil, for the period from January of 2012 to April of 2017. In the sample as a whole, we determined the total number of spirometry tests performed, and the frequency of the tests in individuals ≥ 60 years of age, ≥ 65 years of age, and by decade of age, from age 60 onward. In the extremely elderly, we evaluated the quality of spirometry using criteria of acceptability and reproducibility, as well as examining the variables that can influence that quality, such a cognitive deficit. Results: The sample comprised a total of 4,126 spirometry tests. Of those, 961 (23.30%), 864 (20.94%), 102 (2.47%), and 26 (0.63%) were performed in individuals ≥ 60, ≥ 65, ≥ 86, and ≥ 90 years of age (defined as extreme old age), respectively. In the extremely elderly, the criteria for acceptability and reproducibility were met in 88% and 60% of the spirometry tests (95% CI: 75.26-100.00 and 40.80-79.20), respectively. The cognitive deficit had a negative effect on acceptability and reproducibility (p ≤ 0.015 and p ≤ 0.007, respectively). Conclusions: A significant number of elderly individuals undergo spirometry, especially at ≥ 85 years of age, and the majority of such individuals are able to perform the test in a satisfactory manner, despite their advanced age. However, a cognitive deficit could have a negative effect on the quality of spirometry.


RESUMO Objetivo: Determinar a frequência de idosos que realizaram espirometria num serviço de função pulmonar, e avaliar a qualidade da realização do exame na velhice extrema e se a idade cronológica influencia essa qualidade. Métodos: Estudo transversal retrospectivo utilizando informações (espirometria e questionário respiratório) de um banco de dados de um serviço de função pulmonar em Aracaju (SE) entre janeiro de 2012 e abril de 2017. Com base na amostra geral, determinou-se o número total de espirometrias realizadas em todas as idades, em idosos ≥ 60 anos, ≥ 65 anos, e por década de idade a partir da sexta década. Na velhice extrema, avaliou-se a qualidade da espirometria utilizando critérios de aceitabilidade e reprodutibilidade, e investigaram-se variáveis que influenciam essa qualidade, tal como déficit cognitivo. Resultados: A amostra geral foi composta por 4.126 espirometrias. Dessas, 961 (23,30%), 864 (20,94%), 102 (2,47%) e 26 (0,63%) foram realizadas em idosos com ≥ 60 anos de idade, ≥ 65 anos, ≥ 86 anos e ≥ 90 anos (velhice extrema), respectivamente. Na velhice extrema, os critérios de aceitabilidade e reprodutibilidade foram preenchidos em 88% (IC95%: 75,26-100,00) e 60% (IC95%: 40,80-79,20) das espirometrias, respectivamente. O déficit cognitivo influenciou negativamente a aceitabilidade e a reprodutibilidade (p ≤ 0,015; e p ≤ 0,007, respectivamente). Conclusões: Idosos na velhice extrema são uma realidade atual nos serviços de função pulmonar, e a maioria deles é capaz de realizar espirometrias adequadamente, apesar da idade avançada. O déficit cognitivo influencia negativamente a qualidade da espirometria.

ABSTRACT

Introduction: It has been hypothesized that increasing the interstitial hydrostatic pressure within the sinonasal mucosa of patients with nasal polyposis (NP) might decrease the size of nasal polyps. Objective: To evaluate the effects of positive airway pressure, delivered by a continuous positive airway pressure (CPAP) device, in patients with NP and in control subjects. Methods: Twelve patients with NP and 27 healthy subjects were exposed to CPAP (20 cm H2O) for 2 hours. Visual analog scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE) scale, acoustic rhinometry (AR), peak nasal inspiratory flow (PNIF) and nasal endoscopy (NE-Meltzer polyp grading system) were performed before and after the intervention, for all patients. Results: The control group showed a significant worsening in nasal obstruction symptoms, as measured by VAS and NOSE (p < 0.01), and a significant decrease in nasal patency, as measured by the PNIF and AR (p < 0.01). For the NP group, VAS, NOSE, and AR did not differ significantly (p = 0.72, p = 0.73, and p = 0.17, respectively), but PNIF values worsened (p = 0.04) after exposure to CPAP. There was a statistically significant reduction in the nasal polyps' size (p = 0.04). Conclusions: Positive pressure worsened the nasal obstruction symptoms and decreased objective parameters of nasal patency in control subjects. In patients with NP, exposure to CPAP reduced the nasal polyps' size, and the nasal patency, asmeasured by PNIF. However, it had no significant effects in AR and in nasal obstruction symptoms (AU)

ABSTRACT

OBJECTIVE: We investigated the opinions of experts to identify problems and prepare an improvement plan when applying the Korean Triage and Acuity Scale (KTAS) to pediatric patients in the emergency department. METHODS: The experts comprised 15 researchers at a pediatric emergency center designated by the Ministry of Health and Welfare and research team members of the Korean Society of Pediatric Emergency Medicine. The first survey was an open-ended question about the problems, application results, and remedies of applying KTAS to children through e-mail. The problems were categorized by topic, and degree of agreement was presented using a 9-point Likert scale. RESULTS: In the first survey, 67% of experts participated and 18 problems were identified. In the second survey, 73% of experts participated and eight problems were identified in four categories, validity, reliability, feasibility and other opinions. All experts pointed out that resources were not considered during pediatric triage in the KTAS. Ninety-one percent of experts said that peak expiratory flow rate measurement and Glasgow Coma Scale evaluation were unlikely to be feasible. Moreover, 91% experts were concerned that the triage level could be distorted if KTAS was interlocked with medical costs. Eighty-two percent of the respondents pointed to the high triage result of febrile children and the difference in pain score between the evaluators, etc. CONCLUSION: Based on the problems pointed out by experts and the reality of Korea's emergency departments, it is necessary to consider revision of KTAS for children.

ABSTRACT

A poluição do ar é o maior fator de risco ambiental à saúde no mundo, responsável por um grande impacto na mortalidade e na morbidade, sobretudo por doenças respiratórias e cardiovasculares. Portanto, o objetivo principal deste estudo foi avaliar os efeitos agudos da poluição do ar ambiente no pico de fluxo expiratório e na pressão arterial. A população do estudo foi constituída de indivíduos adultos, profissionais de saúde do Centro Municipal de Saúde João Barros Barroso (local da coleta dos dados), localizado no bairro de Copacabana, no município do Rio de Janeiro, no período de 24 de julho de 2016 a 27 de julho de 2017. Os poluentes do ar ambiente pesquisados foram: material particulado inalável (PM10), dióxido de enxofre (SO2), monóxido de carbono (CO), ozônio (O3) no dia corrente (lag0) e nas defasagens de 24 h/dia cada lag dos três dias anteriores (1 dia prévio-lag1, 2 dias-lag2 e 3 dias-lag3) e as médias móveis de dois dias prévios (m2=(lag0+lag1+lag2)/3) e de três dias antecedentes (m3= (lag0+lag1+lag2+lag3)/4). Dois estudos foram produzidos. O primeiro, um estudo longitudinal de medidas repetidas, em cinco fases com intervalos irregulares de meses, englobando 96 indivíduos na fase 1 (baseline). O objetivo deste estudo foi avaliar os efeitos agudos da poluição do ar ambiente (PM10, SO2, CO, O3) no pico de fluxo expiratório (PFE) e na pressão arterial de adultos. O modelo de efeitos mistos foi utilizado nas estimativas dos efeitos da poluição do ar nos desfechos (PFE, pressão arterial sistólica e diastólica). O achado mais relevante foi a redução do PFE em 5,05 L/min (IC95%: -8,89; -1,21) no lag0 associada ao acréscimo de 10µg/m³ de O3 (p<0,05). Os demais poluentes (PM10, SO2, CO) não apresentaram efeitos consistentes e significativos. Em relação à pressão arterial (sistólica-PAS e diastólica-PAD), esta não sofreu efeitos significativos e plausíveis dos poluentes do ar. O segundo estudo foi um desenho transversal durante a terceira fase da pesquisa anterior, com uma amostra de 70 indivíduos. O objetivo deste foi propor um modelo preditivo do PFE associado aos poluentes do ar ambiente- PM10, SO2, CO, O3 - e à pressão arterial. Para a construção deste modelo, a estratégia primária foi aplicar a equação de referência de Leiner et al., (1963) no PFE de cada participante para homogeneizar este parâmetro pulmonar nas variáveis determinantes mais importantes (sexo, altura e idade), sendo o PFE% do predito (PFEperc), a variável do desfecho resultante deste processo. Esta medida levou à redução da variabilidade do PFE entre os indivíduos, ressaltando as demais variáveis explicativas, entre elas a exposição à poluição do ar e a pressão arterial. O modelo final obtido por regressão linear múltipla e critério de seleção Akaike's Information Criterion foi descrito como: PFEperc=ɑ+PAS+PM10lag3. Este achado permitiu explorar a associação entre a pressão arterial e a função pulmonar e o efeito agudo negativo de 9,85 (IC95%: -1,7; -0,26) L/min do acréscimo de 10µg/m³ de PM10 no PFE% do predito. Em síntese, os efeitos agudos da poluição do ar foram encontrados no PFE, mas não na pressão arterial


Air pollution is the largest environmental risk factor for health in the world, responsible for a major impact on mortality and mortality, especially respiratory and cardiovascular diseases. The main objective of this study was to evaluate the acute effects of ambient air pollution on peak expiratory flow and blood pressure. The study population consisted of adult individuals, health professionals from the João Barros Barroso Municipal Health Center (where the research was done), located in Copacabana in the municipality of Rio de Janeiro from July 24, 2016 to July 27, 2017. The pollutants of the ambient air assessed were: inhalable particulate matter (PM10), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3) on the current day' exposure (lag0) and in the lags of 24hs /day each lag of exposure over the three preceding days (1 day previous-lag1, 2 dias-lag2 e 3 dias-lag3) and moving averages of two previous days (m2=(lag0+ lag1+ lag2)/3) and three days previous (m3= (lag0+ lag1+ lag2+ lag3)/4). Two studies were performed. The first, a longitudinal study of repeated measures, in five phases with irregular intervals of months, including 96 individuals in phase 1(baseline). The objectives of this study were to evaluate the acute effects of ambient air pollution (PM10, SO2, CO, O3) on peak expiratory flow (PEF) and adult blood pressure. The mixed effects models were used in the estimation of the effects of air pollution with outcomes. (PEF and systolic and diastolic blood pressure). The most relevant finding was the reduction in PEF of 5.05 L/min (IC95%: -8.89;-1.21) in the current day' exposure associated with increase of 10µg/m³ de O3 (p<0.05). The other pollutants (PM10, SO2, CO) did not present consistent and significant effects. In relation to blood pressure (systolic-SBP and diastolic-DBP) this did not suffer significant and plausible effects of air pollutants. The second study was a cross-sectional design, during the third phase of the previous research, with a sample of 70 individuals. For the construction of this model, the primary strategy was to apply the reference equation of Leiner et al., (1963) in the PEF of each participant to homogenize this pulmonary parameter in the most important determinants (sex, height and age), with the predicted PEF(PFEperc) being the outcome variable resulting from this process. This measure led to the reduction of PEF variability among individuals, highlighting the other explanatory variables, among them exposure to air pollution and blood pressure. The final model obtained by multiple linear regression and selection criterion Akaike's Information Criterion was described as: PEFperc= ɑ+ PAS+PM10lag3. This finding allowed to explore the association between blood pressure and pulmonary function and the short effect in decrease 9.85(IC95%:-1.7;-0.26) L/min associated with increase of 10µg/m³ on PM10 in the PEF% predicted. In summary, the acute effects of air pollution were found in PEF, but not in blood pressure

ABSTRACT

ABSTRACT: Introduction: High particulate matter (PM10) concentrations are associated with increased incidence of respiratory symptoms and decreased lung function. This study evaluates the air pollution effects in children's and adolescents' lung function using peak expiratory flow (PEF) measurements over a given period, in an area exposed to industrial emissions. Methodology: This was a panel study. The effects of air pollution on respiratory symptoms and PEF were investigated in 117 children and adolescents from three public schools in areas of exposure to air pollution from a mining company in a Brazilian medium-sized city, from 2008 to 2009. The average daily PM10, temperature and humidity were recorded by the monitoring network in the region. Association between daily records of PEF and PM10 was assessed in mixed-effect regression models, controlling for temperature, humidity, and body mass index. Results: About 60,000 PEF measurements were performed. Increases of 14µg/m3 in PM10 were associated with decreased PEF in the morning (-1.04%, 95%CI -1.32; -0.77) and evening (-1.2%, 95%CI -1.49, -0.92). Discussion: We found a significant negative association between particulate matter and peak expiratory flow rate in this population, and these remained significant even after adjusted for temperature, humidity, body mass index, coughing, wheezing and coryza. Conclusion: Adverse effects were found and it suggests an association between increase in PM10 and reduced lung function.


RESUMO: Introdução: Altas concentrações de material particulado (MP10) estão associadas com o aumento da incidência de sintomas respiratórios e a diminuição da função pulmonar. Este estudo avalia os efeitos da poluição do ar na função pulmonar de crianças e adolescentes, usando medições de pico de fluxo expiratório por determinado período, em área exposta a emissões industriais. Metodologia: Este é um estudo de painel. Os efeitos da poluição nos sintomas respiratórios e no pico de fluxo expiratório (PEF) foram investigados em 117 crianças e adolescentes, em três escolas públicas localizadas na área de dispersão da pluma dos poluentes emitidos por uma indústria de mineração em uma cidade brasileira de médio porte, em 2008 e 2009. Médias diárias de MP10, temperatura e umidade foram coletadas pela rede de monitoramento na região. Associação entre registros diários de PEF e de MP10 foi avaliada utilizando modelos de regressão de efeito misto, controlando por temperatura, umidade e índice de massa corporal (IMC). Resultados: Cerca de 60 mil medidas de PEF foram realizadas. Aumentos de 14 µg/m3 de MP10 foram associados com diminuições das medições do PEF da manhã (-1,04%, intervalo de confiança de 95% - IC95% -1,32; -0,77) e à noite (-1,2%, IC95% -1,49; -0,92). Discussão: Neste estudo encontramos associação negativa significativa entre exposição a MP10 e pico de fluxo expiratório. Essas associações permaneceram significativas mesmo após o ajuste para temperatura, umidade, IMC, sexo, tosse, chiado e coriza. Conclusão: Os efeitos adversos foram encontrados sugerindo associação entre o aumento de MP10 e a função pulmonar reduzida.

ABSTRACT

OBJECTIVE: To investigate the relationship between peak cough flow (PCF), pulmonary function tests (PFT), and severity of dysphagia in patients with ischemic stroke. METHODS: This study included patients diagnosed with ischemic stroke, who underwent videofluoroscopic swallowing study (VFSS), PCF and PFT from March 2016 to February 2017. The dysphagia severity was assessed using the videofluoroscopic dysphagia scale (VDS). Correlation analysis of VDS, PFT and PCF was performed. Patients were divided into three groups based on VDS score. One-way ANOVA of VDS was performed to analyze PCF, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and age among the different groups. RESULTS: The correlation coefficients of VDS and PCF, VDS and FVC, and VDS and FEV1 were -0.836, -0.508, and -0.430, respectively, all of which were statistically significant at the level of p < 0.001. The one-way ANOVA indicated statistically significant differences in PCF, FVC, FEV1, and age among the VDS groups. Statistically significant differences in VDS and age were observed between aspiration pneumoia and non-aspiration pneumonia groups. CONCLUSION: Coughing is a useful factor in evaluating the risk of aspiration in dysphagia patients. Evaluation of respiratory and coughing function should be conducted during the swallowing assessment of patients with ischemic stroke.

ABSTRACT

Abstract Introduction: A combination of antihistamines and oral corticosteroids is often used to treat acute symptoms of allergic rhinitis. Objective: To evaluate safety and efficacy of desloratadine plus prednisolone in the treatment of acute symptoms of children (2-12 years) with allergic rhinitis, and to compare it to dexchlorpheniramine plus betamethasone. Methods: Children with moderate/severe persistent allergic rhinitis and symptomatic (nasal symptoms score [0-12] ≥ 6) were allocated in a double-blind, randomized fashion to receive dexchlorpheniramine plus betamethasone (n = 105; three daily doses) or desloratadine plus prednisolone (n = 105; single dose followed by two of placebo) for 7 days. At the beginning and end of the evaluation, the following were obtained: nasal symptoms score, extra nasal symptoms score, peak nasal inspiratory flow, blood biochemistry, and electrocardiogram. Ninety-six children of the dexchlorpheniramine plus betamethasone group and 98 of the desloratadine plus prednisolone group completed the protocol. Results: The two groups were similar regarding initial and final nasal symptoms scores, extra nasal symptoms scores and peak nasal inspiratory flow. A drop of 76.4% and 79.1% for nasal symptoms score, 86.0% and 79.2% for extra nasal symptoms score, as well as an increase of 25.2% and 24.3% for peak nasal inspiratory flow occurred for those treated with desloratadine plus prednisolone and dexchlorpheniramine plus betamethasone, respectively. There were no significant changes in blood chemistry. Sinus tachycardia was the most frequent electrocardiogram change, but with no clinical significance. Drowsiness was reported significantly more often among those of dexchlorpheniramine plus betamethasone group (17.14% × 8.57%, respectively). Conclusion: The desloratadine plus prednisolone combination was able to effectively control acute symptoms of rhinitis in children, improving symptoms and nasal function. Compared to the dexchlorpheniramine plus betamethasone combination, it showed similar clinical action, but with a lower incidence of adverse events and higher dosing convenience.


Resumo Introdução: A associação entre anti-histamínicos e corticosteroides orais é frequentemente empregada no tratamento de sintomas agudos de rinite alérgica. Objetivo: Avaliar a segurança e eficácia da associação desloratadina + prednisolona no tratamento de sintomas agudos de crianças (2-12 anos) com rinite alérgica e compará-las com as da associação dexclorfeniramina + betametasona. Método: Crianças com rinite alérgica persistente moderada/grave e sintomáticas (escore de sintomas nasais [0-12] ≥ 6) foram alocadas de modo duplo-cego e randômico para receber dexclorfeniramina + betametasona (n = 105; três doses diárias) ou desloratadina + prednisolona (n = 105; dose única seguida por duas de placebo) por 7 dias. No início e no fim da avaliação foram obtidos: escore de sintomas nasais, escore de sintomas extranasais, pico de fluxo inspiratório nasal, bioquímica sanguínea e eletrocardiograma. Do total, 96 crianças do grupo dexclorfeniramina + betametasona e 98 do grupo desloratadina + prednisolona concluíram o protocolo. Resultados: Os dois grupos foram iguais com relação ao escore de sintomas nasais, escore de sintomas nasais extranasais e pico de fluxo inspiratório nasal iniciais e finais. Observou-se queda de 76,4% e 79,1% nos escores para escore de sintomas nasais, de 86,0% e 79,2% para escore de sintomas extranasais, assim como incremento de 25,2% e de 24,3% para o pico de fluxo inspiratório nasal para os grupos desloratadina + prednisolona e dexclorfeniramina + betametasona, respectivamente. Não houve alterações significativas da bioquímica sanguínea. Taquicardia sinusal foi a alteração do eletrocardiograma mais encontrada, mas sem significância clínica. Sonolência foi significantemente mais referida entre os tratados com dexclorfeniramina + betametasona do que entre os desloratadina + prednisolona (8,57% × 17,14%, respectivamente). Conclusão: A associação desloratadina + prednisolona foi capaz de controlar efetivamente os sintomas agudos de rinite em crianças, melhorou sintomas e a função nasal. Na comparação com a associação dexclorfeniramina + betametasona, demonstrou ação clínica semelhante, mas com menor incidência de eventos adversos e maior comodidade posológica.
