RESUMO

BACKGROUND & AIMS: The bioimpedence phase angle has been considered as a predictor for morbidity and mortality in different clinical situations, although reference values from a large healthy population are lacking. The aim of this meta-analysis is to estimate mean phase-angle values in healthy individuals. METHODS: This meta-analysis systematically searched MEDLINE, EMBASE, The Cochrane Controlled Trials Register, SCIELO, LILACS, CINAHL, Web of Science and gray literature for studies estimating mean phase angles. Quality of evidence was assessed for all studies and subgroup (males and females) meta-analysis stratified by age group according to literature (up to 2; 3-5; 6-12; 13-15; 16-18; 19-28; 29-38; 39-48; 49-58; 59-69; 70-80 and >80 years of age) were conducted using random-effects models. RESULTS: A total of 46 studies including 249,844 subjects were selected for the present analysis. Males show a pooled estimate of the mean phase angle of 3.6 (95% CI: 3.0-4.1) for infants (0-2 y), increasing progressively to 7.3 (95% CI: 7.0-7.5) at the teenage phase (16-18 y), stabilizing during adult ages (18-38) and decreasing progressively with ongoing years with an estimate of 5.3 (95% CI: 4.5-6.0) for elderly above 80 years old. Similarly, females start from 3.7 (95% CI: 3.2-4.3) for infants (0-2 y), increasing progressively to 6.4 (95% CI: 6.1-6.8) at the teenage phase (16-18 y), stabilizing during adult ages (18-48) and decreasing progressively with ongoing years with an estimate of 5.4 (95% CI: 5.3-5.6) for elderly above 80 years old. Also, males have higher estimates than females for all age groups except for infants (0-2) and subjects older than 80 years old. Heterogeneity was high for all age groups. CONCLUSIONS: In both sexes, phase-angle values have a similar pattern that start from infants, increase progressively up to the teenage phase, stabilize during adult ages, and then decrease progressively in older subjects and the elderly.

RESUMO

PURPOSE: Recent studies suggest that body mass index is not a reliable enough measurement for body composition in individuals, particularly in older and younger people. However, most research on body image has used the body mass index (BMI) as a physiological predictor of body satisfaction, particularly in children. The aim of this study was to investigate whether body composition is a better predictor of body size dissatisfaction in children than BMI. METHODS: This is a cross-sectional study. Healthy children and adolescents aged 5-19 years, sex male and female, were recruited using a convenience sample in Brazil. BMI was measured according to the international standardization method and body composition was measured by bioelectrical impedance analysis (BIA) with a portable device model (BIA InBodyS10 multi-frequency, USA). Body size dissatisfaction was assessed using the Kakeshita's Figure Rating Scale for Brazilian Children. Data were analyzed with logistic regression analysis. RESULTS: A total of 547 participants were evaluated, including 54% females and 67% Caucasian, with a mean age of 11.4 ± 3.8 years. The mean BMI was 20.5 ± 4.6 kg/m2, and the mean percentages of fat and lean mass were 23.01 ± 10.59% and 72.84 ± 10.03%, respectively. In the multivariable model, only body composition was significantly associated with body size dissatisfaction (odds ratio: 1.849 (1.085-3.149, p = 0.024) and 1.828 (1.043-3.202, p = 0.035), respectively). CONCLUSIONS: Body composition measures can better predict body size dissatisfaction in children and adolescents than BMI. This result may be relevant for the design of future studies on physiological indicators and body satisfaction. LEVEL OF EVIDENCE: Level V, cross-sectional study.

RESUMO

Abstract Objective: To validate the Brazilian Portuguese version of the Family Environment Assessment questionnaire (Inventaire du Milieu Familial). Methods: The validation process was carried out in two stages. First, translation and back-translation were performed, and in the second phase, the questionnaire was applied in 72 families of children between 0 and 24 months for the validation process. The tool consists of the following domains: mother's communication ability; behavior; organization of the physical and temporal environment; collection/quantity of toys; maternal attitude of constant attention toward her baby; diversification of stimuli; baby's behavior. The following was performed for the scale validation: 1 - content analysis (judgment); 2 - construct analysis (factorial analysis - Kaiser-Meyer-Olkin, Bartlett, and Pearson's correlation tests); 3 - criterion analysis (calculation of Cronbach's alpha coefficient, intraclass correlations, and split-half correlations). Results: The mean age of the children was 9 ± 6.7 months, and of these, 35 (48.6%) were males. Most correlations between items and domains were significant. In the factorial analysis of the scale, Kaiser-Meyer-Olkin values were 0.76, Bartlett's test showed a p-value < 0.001, and correlation between items and domains showed a p-value < 0.01. Regarding the validity, Cronbach's alpha was 0.92 (95% CI: 0.89-0.94). The intraclass correlation among the evaluators was 0.97 (0.96-0.98) and split-half correlations, r: 0.60, with p < 0.01. Conclusions: The Portuguese version of the Inventaire du Milieu Familial showed good to excellent performance regarding the assessed psychometric properties.

RESUMO

Abstract Objective: To validate the Pediatric Obstructive Sleep Apnea Screening tool for use in Brazil. Materials and methods: The Brazilian version of this questionnaire, originally validated and tested in the United States, was developed as follows: (a) translation; (b) back-translation; (c) completion of the final version; (d) pre-testing. The questionnaire was applied prior to polysomnography to children aged 3-9 years from October 2015 to October 2016, and its psychometric properties (i.e., validity and reliability) were evaluated. The accuracy was assessed from comparisons between polysomnographic results and corresponding questionnaire scores. Results: Sixty patients were enrolled, and based on polysomnographic findings, 48% patients had normal apnea-hypopnea index, while the remaining 52% met the criteria for obstructive sleep apnea. Minimum O2 saturation level was significantly lower among obstructive sleep apnea children (p = 0.021). Satisfactory concordance was found between individual apnea-hypopnea index and questionnaire scores. Bland-Altman plot-derived bias was 0.1 for the difference between measures, with 5.34 (95% CI: 4.14-6.55) and −5.19 (95%CI: −6.39 to −3.98) for the upper and lower agreement range. Internal consistency derived from Cronbach's alpha was 0.84 (95%CI: 0.78-0.90). Conclusion: The questionnaire was translated to and validated into Brazilian-Portuguese version, and showed good reliability and concordance with apnea-hypopnea index. This questionnaire offers a reliable screening option for sleep-disordered breathing in children.


Resumo Objetivo: Validar o questionário Pediatric Obstructive Sleep Apnea Screening Tool para o seu uso no Brasil. Materiais e métodos: A versão brasileira desse questionário, originalmente validado e testado nos Estados Unidos, foi desenvolvida a partir das seguintes etapas: a) tradução; b) retrotradução; c) conclusão da versão final; d) pré-teste. O questionário foi aplicado previamente ao início da polissonografia em crianças de 3 a 9 anos incluídas no estudo de outubro de 2015 a outubro de 2016. As propriedades psicométricas avaliadas foram validade e confiabilidade. A acurácia foi avaliada pela comparação entre os resultados da polissonografia com o escore do questionário. Resultados: Foram incluídos no estudo 60 pacientes. Conforme a polissonografia, 48% dos pacientes apresentaram índices de apneia e hipopneia normais e 51% apresentaram resultados alterados. A SpO2 mínima foi significativamente menor (p = 0,021) nas crianças com diagnóstico de síndrome de apneia obstrutiva do sono. O índice de apneia e hipopneia apresentou concordância satisfatória com os resultados do questionário. O viés médio de Bland-Altman foi de 0,1 para a diferença entre as medidas, com um limite superior de 5,34 (IC95%4,14 a 6,55) e um limite inferior de -5,19 (IC95%-6,39 a -3,98). A consistência interna do questionário avaliada pelo α de Cronbach foi de 0,84 (IC95%0,78 a 0,90). Conclusão: O questionário foi traduzido e validado adequadamente para a versão em português brasileiro, apresentando boa confiabilidade e concordância com o índice de apneia e hipopneia. Esse questionário oferece uma opção confiável de triagem de distúrbios respiratórios do sono em crianças.

RESUMO

BACKGROUND: Experimental data show that type I interferon has a key role in innate immune response against influenza infection. OBJECTIVE: We compared nasal levels of interferon-α2 and ß among inpatients and outpatients with influenza. STUDY DESIGN: Children younger than 5 years of age with influenza-like illness seeking care at the emergency department within the first 72 h of disease onset were prospectively included. Clinical and demographic data and secretions through nasal wash were obtained. Influenza infection was assessed through reverse-transcription polymerase chain reaction and nasal levels of interferon-α2 and ß were measured by enzyme-linked immunosorbent assay. All patients followed until the end of the disease. RESULTS: One hundred patients were included, of which 24 had confirmed influenza infection, and 5 of them were hospitalized. Subtypes A (H3N2) and B were confirmed in 10 and 14 patients, respectively. Seventy-six patients without influenza, including 48% of outpatients, were recruited as controls. All hospitalized patients were significantly younger regardless of influenza status (age <6 months in 59% vs. 23.2%, p < 0.001). All other data were similar among the groups. Comparing median levels of interferon-α2 among children with influenza, levels were significantly higher in outpatients than in hospitalized patients and were 263.2 pg/mL (25-75 interquartile range: 58.3-634) and detectable in only one patient (90 pg/mL), respectively. The levels of interferon-α2 in controls and those of interferon-ß in all groups were not detected. CONCLUSIONS: Higher levels of interferon-α2 in patients with less severe influenza reinforce experimental evidence about the protective role of interferon-α2 against influenza infection.

RESUMO

Introduction: Studies have demonstrated the relevance of anthropometric indicators in the prediction of metabolic syndrome (MetS). However, researches involving older people are still scarce. Therefore, the objective was to describe the frequency of MetS and to determine the performance of anthropometric indicators as predictors of MetS in the total sample, in men and women. Methods: Cross-sectional study involving 479 elderly individuals attended in primary health care. The revised National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII) guidelines were used for the MetS diagnosis. The anthropometric indicators evaluated were neck circumference, sagittal abdominal diameter (SAD), SAD/height, sagittal index, and conicity index (C-Index). The predictive performance of the MetS anthropometric indicators was determined using a receiver operating characteristic (ROC) curve. A cutoff point >0.700 was used to evaluate diagnostic performance. Results: The frequency of MetS was 60.5%. The anthropometric indicators demonstrating adequate performance were in total sample: SAD/height (auROC = 0.810), SAD (auROC = 0.777), and C-Index (auROC = 0.706); in women: SAD (auROC = 0.820), SAD/height (auROC = 0.810), neck circumference (auROC = 0.782), and C-Index (auROC = 0.727); in men: SAD/height (auROC = 0.768), SAD (auROC = 0.760), and C-Index (auROC = 0.724). Conclusions: A high frequency of MetS was observed. Of the five anthropometric indicators investigated, three presented good performance in the total sample (SAD, SAD/height, and C-Index), four in women (SAD, SAD/height, neck circumference, and C-Index), and three in men (SAD, SAD/height, and C-Index). The anthropometric indicators, SAD, SAD/height, and C-Index, proved to perform adequately in all the three segments investigated.

RESUMO

AIMS: To validate the Brazilian version of the Fresno test of competence in Evidence-Based Medicine. METHODS: This is a cross-sectional, validation study. Phase 1: translation of the Fresno instrument. Phase 2: validation of the translated version, which was tested in 70 undergraduate medical students. The psychometric properties evaluated were validity, internal consistency, and sensitivity to change. RESULTS: Overall, validity was adequate; most items showed a moderate to strong and significant correlation with the total score; there was an important and significant difference between both groups, with and without previous contact with Evidence-Based Medicine (median, 55 [IQ25-75, 45.2-61.7] vs. median, 18.5 [IQ25-75, 6.0-29.7]) (p<0.001). Internal consistency was also adequate (α-C 0.718), and sensitivity to change showed a considerable and significant difference between pre and post-test (median, 18.5 [IQ25-75, 6.0-29.7] vs. median, 44 [IQ25-75, 34.0-60.0]) (p<0.001). CONCLUSIONS: The Brazilian version of the Fresno test showed satisfactory psychometric properties, and it can now be used as a tool to assess the knowledge and skills of Evidence-Based Medicine in Brazilian medical students.

RESUMO

This article aims to review systematically the evidence on nutritional assessment techniques and parameters used to determine the nutritional status of children and adolescents. The literature review and the selection of publications were performed using the Medline, Lilacs, SciELO, Embase, personal files. 17 studies were identified, 7 addressed the anthropometric indices as the main outcome, 7 analyzed the growth and development of children and adolescents through growth curves, and the remainder surveyed body composition. In general, all met the quality criteria, unless 6 of the articles who did not discuss the limitations. The literature review suggests several techniques and parameters that can be applied to determine the nutritional status of children and adolescents from different countries. Growth graphs are essential to assess the health of children, but depend greatly of the growth tables used. Although BMI can be practical, it does not distinguish body fat from lean mass. The best interpretation of anthropometry will depend of valid reference values for age range of the study population. BIA is a quick feasible method, but the measurement has some various nationalities.

Resumo O objetivo deste artigo é revisar sistematicamente as evidências sobre as técnicas de avaliação nutricional e parâmetros utilizados para determinar o estado nutricional em crianças e adolescentes. Revisão da literatura com busca nas bases de dados, Medline, Lilacs, SciELO e Embase, além de arquivos pessoais. Identificamos 17 artigos que relatavam dados de diferentes populações, sete estudos abordaram os índices antropométricos, quatro o crescimento e o desenvolvimento de crianças e adolescentes por meio de curvas de crescimento, e o restante a composição corporal. Todos preencheram os critérios de qualidade, com exceção das limitações. A revisão da literatura sugere diversas técnicas e parâmetros que podem ser aplicados para determinar o estado nutricional de crianças e adolescentes de diferentes países. Gráficos de crescimento são essenciais para avaliar a saúde de crianças, mas depende muito das tabelas de crescimento utilizadas. Embora o IMC seja prático, não distingue a gordura corporal de massa magra. Existem várias técnicas para avaliar proporções, tamanho e composição corporal. A melhor interpretação da antropometria dependerá de valores de referência válidos para a faixa etária da população estudada. BIA é um método factível, mas tem algumas limitações para a realização do exame.

RESUMO

Severe therapy-resistant asthma (STRA) is characterized by frequent symptoms, asthma exacerbations and hospitalizations, despite the use of continuous high-dose corticosteroid therapy and other controller medications. Inflammation of the airways and symptoms varies widely in children with STRA and most patients present only with mild lung function abnormalities. Low Th2 cell response (1), low IL-10 production and increased IL-33 have been reported in this group of patients (2,3). This article is protected by copyright. All rights reserved.

RESUMO

OBJECTIVE: To evaluate the relationship between physical activity and phase angle. DESIGN: Systematic Review and Meta-analysis. DATA SOURCES: Electronic searches of MEDLINE (via PUBMED), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), SciELO, LILACS, SPORTDiscus, Scopus, and Web of Science from inception to December 10th, 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: The PICOS strategy was defined, in which "P" corresponded to participants of any age, sex or ethnicity, "I" indicated any type of physical activity program, "C" denoted lack of exercise or irregular physical activity, "O" corresponded to the phase angle obtained by bio-impedance, and "S" indicated longitudinal or cross-sectional studies. RESULTS: In cross-sectional studies the phase angle was higher among the active individuals (MD = 0.70; 95% CI: 0.48, 0.92, P < 0.001), with low heterogeneity (I2 = 0%; P = 0.619). In longitudinal studies, the mean of the difference of phase angles from the baseline was significantly higher for the active group than the control group (MD = 0.30; 95% CI: 0.11, 0.49, P = 0.001), with low heterogeneity (I2 = 13%, P = 0.331). No evidence of publication bias was found and the overall risk of bias was moderate to high. SUMMARY/CONCLUSION: The positive association of physical activity with phase angle reinforces the importance of routinely including exercise in health care. We also identified the need for further studies to define with different types, intensities and frequencies of exercises should be conducted in order to find the best dose-effect relationship.

RESUMO

Abstract Objective: To evaluate the overall health-related quality of life in patients with bronchiolitis obliterans. Methods: Participants with a diagnosis of post-infectious bronchiolitis obliterans, who were being followed-up at two specialized outpatient clinics of Pediatric Pulmonology in Porto Alegre, Brazil, and controls aged between 8 and 17 years, of both genders, were included in the study. Controls were paired by gender, age, and socioeconomic level in relation to the group of participants with post-infectious bronchiolitis obliterans. The version of the Pediatric Quality of Life Inventory (PedsQ) tool validated for Brazil was applied for the assessment of Health-related Quality of Life, through an interview. The comparison of the Health-related Quality of Life means between the groups was performed using Student's t-test for independent samples and the chi-squared test, for categorical variables. Results: 34 patients diagnosed with post-infectious bronchiolitis obliterans and 34 controls participated in the study. The mean age of the children included in the study was 11.2 ± 2.5 years, and 49 (72%) of them were males. The groups showed no significant differences in relation to these variables. The quality of life score was significantly and clinically lower in the post-infectious bronchiolitis obliterans group when compared with controls in the health (72.36 ± 15.6, 81.06 ± 16.4, p = 0.031) and school domains (62.34 ± 20.7, 72.94 ± 21.3, p = 0.043), as well as in the total score (69.53 ± 14.9, 78.02 ± 14.8, p = 0.024), respectively. Conclusion: Patients with post-infectious bronchiolitis obliterans presented lower health-related quality of life scores when compared with healthy individuals in the total score and in the health and school domains.


Resumo Objetivo: Avaliar a qualidade de vida relacionada à saúde geral em participantes com bronquiolite obliterante. Métodos: Foram incluídos no estudo participantes com diagnóstico de bronquiolite obliterante pós-infecciosa que estavam em acompanhamento em dois ambulatórios especializados de pneumologia pediátrica em Porto Alegre, Brasil e controles, entre 8 e 17 anos, de ambos os sexos. Os controles foram pareados por sexo, idade e nível socioeconômico em relação ao grupo de participantes com bronquiolite obliterante pós-infecciosa. Para avaliação da Qualidade de Vida Relacionada à Saúde geral foi aplicado a versão validada para o Brasil do instrumento PedsQL (Pediatric Quality of Life Inventory), por meio de entrevista. A comparação entre as médias da Qualidade de Vida Relacionada à Saúde entre os grupos foi realizada mediante o teste t para amostras independentes e para as variáveis categóricas por teste qui-quadrado. Resultados: Participaram do estudo 34 pacientes com diagnóstico de bronquiolite obliterante pós-infecciosa e 34 controles. A média da idade das crianças incluídas foi de 11,2 ± 2,5 anos e 49 (72%) deles eram do sexo masculino. Os grupos não apresentaram diferenças significativas em relação a essas variáveis. O escore de qualidade de vida foi significativamente e clinicamente menor no grupo bronquiolite obliterante pós-infecciosa em comparação com o controle nos domínios saúde: (72,36 ± 15,6; 81,06 ± 16,4; p = 0,031); escolar: (62,34 ± 20,7; 72,94 ± 21,3; p = 0,043) e no escore total (69,53 ± 14,9; 78,02 ± 14,8, p = 0,024), respectivamente. Conclusão: Os pacientes com bronquiolite obliterante pós-infecciosa apresentam escores de qualidade de vida relacionados à saúde menor do que indivíduos saudáveis no escore total e nos domínios saúde e escolares.

RESUMO

OBJECTIVE: To validate the Brazilian Portuguese version of the Family Environment Assessment questionnaire (Inventaire du Milieu Familial). METHODS: The validation process was carried out in two stages. First, translation and back-translation were performed, and in the second phase, the questionnaire was applied in 72 families of children between 0 and 24 months for the validation process. The tool consists of the following domains: mother's communication ability; behavior; organization of the physical and temporal environment; collection/quantity of toys; maternal attitude of constant attention toward her baby; diversification of stimuli; baby's behavior. The following was performed for the scale validation: 1 - content analysis (judgment); 2 - construct analysis (factorial analysis - Kaiser-Meyer-Olkin, Bartlett, and Pearson's correlation tests); 3 - criterion analysis (calculation of Cronbach's alpha coefficient, intraclass correlations, and split-half correlations). RESULTS: The mean age of the children was 9±6.7 months, and of these, 35 (48.6%) were males. Most correlations between items and domains were significant. In the factorial analysis of the scale, Kaiser-Meyer-Olkin values were 0.76, Bartlett's test showed a p-value<0.001, and correlation between items and domains showed a p-value<0.01. Regarding the validity, Cronbach's alpha was 0.92 (95% CI: 0.89-0.94). The intraclass correlation among the evaluators was 0.97 (0.96-0.98) and split-half correlations, r: 0.60, with p<0.01. CONCLUSIONS: The Portuguese version of the Inventaire du Milieu Familial showed good to excellent performance regarding the assessed psychometric properties.

RESUMO

OBJECTIVE: To validate the pediatric obstructive sleep apnea screening tool for use in Brazil. MATERIALS AND METHODS: The Brazilian version of this questionnaire, originally validated and tested in the United States, was developed as follows: (a) translation; (b) back-translation; (c) completion of the final version; (d) pre-testing. The questionnaire was applied prior to polysomnography to children aged 3-9 years from October 2015 to October 2016, and its psychometric properties (i.e., validity and reliability) were evaluated. The accuracy was assessed from comparisons between polysomnographic results and corresponding questionnaire scores. RESULTS: Sixty patients were enrolled, and based on polysomnographic findings, 48% patients had normal apnea-hypopnea index, while the remaining 52% met the criteria for obstructive sleep apnea. Minimum O2 saturation level was significantly lower among obstructive sleep apnea children (p=0.021). Satisfactory concordance was found between individual apnea-hypopnea index and questionnaire scores. Bland-Altman plot-derived bias was 0.1 for the difference between measures, with 5.34 (95% CI: 4.14-6.55) and -5.19 (95%CI: -6.39 to -3.98) for the upper and lower agreement range. Internal consistency derived from Cronbach's alpha was 0.84 (95%CI: 0.78-0.90). CONCLUSION: The questionnaire was translated to and validated into Brazilian-Portuguese version, and showed good reliability and concordance with apnea-hypopnea index. This questionnaire offers a reliable screening option for sleep-disordered breathing in children.

RESUMO

Abstract Objective: To compare the effectiveness of a single intramuscular dose of bromopride, metoclopramide, or ondansetron for treating vomiting. Methods: Randomized controlled trial including children 1-12 years of age presenting with acute vomiting at the pediatric emergency department. Outcomes: Number of children that stopped vomiting at one, six, and 24 h following treatment; episodes of diarrhea; acceptance of oral liquids; intravenous rehydration; return to hospital and side effects. Results: There were 175 children who completed the study. Within the first hour after treatment, all drugs were equally effective, with ondansetron preventing vomiting in 100%, bromopride in 96.6%, and metoclopramide in 94.8% of children (p = 0.288). Within six hours, ondansetron was successful in preventing vomiting in 98.3% of children, compared to bromopride and metoclopramide, which were successful in 91.5% and 84.4% of patients, respectively (p = 0.023). Within 24 h, ondansetron was superior to both other agents, as it remained efficacious in reducing vomiting in 96.6% of children, as opposed to 67.8% and 67.2% with bromopride and metoclopramide, respectively (p = 0.001). The ondansetron group showed better acceptance of oral liquids (p = 0.05) when compared to the bromopride and metoclopramide. The ondansetron group did not show any side effects in 75.9% of cases, compared to 54.2% and 53.5% in the bromopride and metoclopramide groups, respectively. Somnolence was the most common side effect. Conclusions: A single dose of ondansetron is superior to bromopride and metoclopramide in preventing vomiting six hours and 24 h following treatment. Oral fluid intake after receiving medication was statistically better with Ondansetronwhile also having less side effects compared to the other two agents.


Resumo Objetivo: Para comparar a eficacia de uma unica dose intramuscular de bromoprida, metoclopramida ou ondansetrona no tratamento de vomito. Métodos: Ensaio controlado randomizado incluindo crianc¸as de 1 a 12 anos de idade que apresentam vomito agudo no departamento de emergencia pediatrica. Desfechos: Numero de crianças que pararam de vomitar 1, 6 e 24 horas apos o tratamento; episodios de diarreia; aceitac¸ao de liquidos orais; reidratac¸ao intravenosa, retorno ao hospital e efeitos colaterais.

RESUMO

BACKGROUND AND RATIONALE: The Transplanted Organ Questionnaire (TOQ), developed in France, is a disease-targeted instrument designed to evaluate what the transplanted organ represents to the recipient in patients who have undergone liver transplantation. The present study sought to validate a version of the TOQ for use in the Brazilian population. Translation and cross-cultural adaptation were carried out in accordance with international standard practices. Convergent validity was measured by correlations between TOQ domains and the Beck Depression Inventory (BDI), while reliability was assessed by measurement of internal consistency (Cronbach's alpha coefficient), reproducibility (intraclass correlation coefficient), sensitivity to change (effect size), and floor and ceiling effects. RESULTS: The study sample comprised 122 liver transplant recipients, with a mean age of 56.7 ± 9.9 years, treated at the outpatient clinic of a tertiary hospital in Southern Brazil. The sample was largely male (57.4%), and the predominant indication for liver transplant was hepatocellular carcinoma (34.4%). The mean total TOQ score was 32.9 ± 18.0. Cronbach's alpha for the total score was 0.89 (95%CI 0.86-0.92). Correlations between TOQ and BDI domains were acceptable, with the rejection domain correlating most strongly (r = 0.37; p ≤ 0.001). In conclusion, the Brazilian Portuguese version of the TOQ exhibited good psychometric performance, suggesting that it can be a useful tool in the Brazilian cultural context.

RESUMO

OBJECTIVE: To evaluate the overall health-related quality of life in patients with bronchiolitis obliterans. METHODS: Participants with a diagnosis of post-infectious bronchiolitis obliterans, who were being followed-up at two specialized outpatient clinics of Pediatric Pulmonology in Porto Alegre, Brazil, and controls aged between 8 and 17 years, of both genders, were included in the study. Controls were paired by gender, age, and socioeconomic level in relation to the group of participants with post-infectious bronchiolitis obliterans. The version of the Pediatric Quality of Life Inventory (PedsQ) tool validated for Brazil was applied for the assessment of Health-related Quality of Life, through an interview. The comparison of the Health-related Quality of Life means between the groups was performed using Student's t-test for independent samples and the chi-squared test, for categorical variables. RESULTS: 34 patients diagnosed with post-infectious bronchiolitis obliterans and 34 controls participated in the study. The mean age of the children included in the study was 11.2±2.5 years, and 49 (72%) of them were males. The groups showed no significant differences in relation to these variables. The quality of life score was significantly and clinically lower in the post-infectious bronchiolitis obliterans group when compared with controls in the health (72.36±15.6, 81.06±16.4, p=0.031) and school domains (62.34±20.7, 72.94±21.3, p=0.043), as well as in the total score (69.53±14.9, 78.02±14.8, p=0.024), respectively. CONCLUSION: Patients with post-infectious bronchiolitis obliterans presented lower health-related quality of life scores when compared with healthy individuals in the total score and in the health and school domains.

RESUMO

INTRODUCTION: The Brazilian childhood National Immunization Program (NIP) introduced live and attenuated varicella vaccination in a single dose, combined as tetraviral vaccine, at 15 months of age in the whole country, during September to December of 2013. The aim of this study was to report trends in incidence of childhood hospital admissions related to varicella and zoster in Brazil from 2003 to 2016, including the first three years after vaccine introduction. METHODS: The number and incidence of hospital admission in patients aged less than 20 years in Brazilian public health system with an admission diagnosis of varicella and zoster from 2003 to 2016 were analyzed and pre (2003-2013) and post-vaccination periods (2014-2016) were compared. The data were obtained from DATASUS, a Brazilian government's open-access public health database system, and analyzed adjusting for secular trend and seasonality if a statistically significant change was found. RESULTS: During the study period, 69,791 admissions due to varicella and herpes zoster occurred in the children younger than 20 years. After adjusting for seasonality, the incidence of hospitalizations decreased from 27.33 to 14.33 per 100000 per year, which corresponds to a reduction of 47.6% (95% confidence interval 18.19-77.04%, p < 0.001) in the vaccinated age group (1-4 years) in 2014-2016 compared to pre-vaccination period. The changes were not significant in the unvaccinated age groups. CONCLUSION: The hospitalizations due to varicella and herpes zoster were decreased by half early after the introduction of a single dose of tetraviral vaccine in NIP in the vaccinated children. Further studies may assess duration and intensity of this effect, as well as the indirect effect in the unvaccinated age groups.
