Avoidance of Inhaled Pollutants and Irritants in Asthma from a Salutogenic Perspective.

Much is known about the role of aeroallergens in asthma, but little is described about the damage caused by inhaled pollutants and irritants to the respiratory epithelium. In this context, the most frequent pollutants and irritants inhaled in the home environment were identified, describing the possible repercussions that may occur in the respiratory tract of the pediatric population with asthma and highlighting the role of the caregiver in environmental control through a salutogenic perspective. Searches were carried out in the MEDLINE/PubMed, Web of Science, Lilacs and Scopus databases for articles considered relevant for the theoretical foundation of this integrative review, in which interactions between exposure to pollutants and inhaled irritants and lung involvement. Articles published in the last 10 years that used the following descriptors were considered: air pollution; tobacco; particulate matter; disinfectants; hydrocarbons, fluorinated; odorants; chloramines; pesticide; asthma; and beyond Antonovsky's sense of coherence. Exposure to smoke and some substances found in cleaning products, such as benzalkonium chloride, ethylenediaminetetraacetic acid and monoethanolamine, offer potential risks for sensitization and exacerbation of asthma. The vast majority of the seven main inhaled products investigated provoke irritative inflammatory reactions and oxidative imbalance in the respiratory epithelium. In turn, the caregiver's role is essential in health promotion and the clinical control of paediatric asthma. From a salutogenic point of view, pollutants and irritants inhaled at home should be carefully investigated in the clinical history so that strategies to remove or reduce exposures can be used by caregivers of children and adolescents with asthma.

Influence of the BsmI polymorphism of the vitamin D receptor gene on the levels of vitamin D, inflammatory and oxidative stress profile in patients with cystic fibrosis supplemented with Colecalciferol megadose.

OBJECTIVE: Evaluate the influence of the BsmI polymorphism of the vitamin D receptor gene on vitamin D levels, and inflammatory and oxidative stress markers in patients with Cystic Fibrosis supplemented with cholecalciferol megadose. METHODS: We performed a single-arm, non-randomized pre- and post-study of 17 patients aged 5 to 20 years with cystic fibrosis diagnosed with vitamin D insufficiency/deficiency 25-hydroxy vitamin< 30 ng/mL. Individuals were genotyped for the BsmI polymorphism of the vitamin D receptor gene and all received cholecalciferol supplementation of 4,000 IU daily for children aged 5 to 10 years and 10,000 IU for children over 10 years of age for 8 weeks. Interviews were conducted with personal data, sun exposure, anthropometric and blood samples of 25-hydroxy vitamin parathormone, serum calcium, ultrasensitive C-reactive protein, alpha 1 acid glycoprotein, total antioxidant capacity, malondialdehyde and kidney and liver function. Inter- and intra-group assessment was assessed by paired t-test Anova test or its non-parametric counterparts. RESULTS: The individuals were mostly male and reported no adverse effects from the use of supplementation, 64 % had 25-hydroxy vitamin levels >30 ng/mL. Patients with BB and Bb genotypes showed increased serum levels of 25-hydroxy vitamin. The group with BB genotype showed a reduction in alpha 1 acid glycoprotein. And individuals with the bb genotype had high levels of malondialdehyde compared to the pre-intervention time. CONCLUSION: It is concluded that variations of the BsmI polymorphism of the vitamin D receptor gene have different responses in vitamin D levels and markers of inflammation and oxidative stress.

Vitamin D levels and their association with oxidative stress and inflammation markers in patients with cystic fibrosis / Niveles de vitamina D y su asociación con marcadores de estrés oxidativo e inflamatorios en pacientes con fibrosis quística

Introduction: cystic fibrosis is a disease that causes inflammation, oxidative stress and metabolic changes that lead to nutrient deficiency, such as vitamin D deficiency. On the other hand, it is suggested that vitamin D has anti-inflammatory and antioxidant actions. Objective: to evaluate the prevalence of hypovitaminosis D and the association between serum 25 hydroxyvitamin D levels with markers of oxidative stress and inflammation in patients with cystic fibrosis. Method: a cross-sectional study was carried out with 48 patients with cystic fibrosis including children, adolescents and adults in the northeast region of Brazil. Blood collection was performed for analysis of 25-hydroxyvitamin D, calcium, parathyroid hormone, inflammatory process (C-reactive protein (CRP) and alpha-1-acid glycoprotein-A1 (A1GPA)) and oxidative stress (malondialdehyde (MDA) and total antioxidant capacity (CAOT)). The statistical analysis was performed using the “Statistical Package for the Social Sciences”, adopting a significance level of p < 0.05. Results: Vitamin D insufficiency/deficiency was found in 64.6 % of patients. After multiple linear regression analysis, MDA showed an inverse association with blood values of 25-Hydroxyvitamin D (p < 0.05) conditioned by the presence of inflammatory process markers. When only oxidative stress was evaluated, this association disappeared. Conclusion: in conclusion, there was a high prevalence of hypovitaminosis D, with 25(OH)D levels associated with greater oxidative stress when combined with inflammatory markers. Improved vitamin D levels may be an alternative to reduce the damage caused by excess oxidative stress and inflammation in CF patients. (AU)

Introducción: la fibrosis quística es una enfermedad que cursa con inflamación, estrés oxidativo y cambios metabólicos que conducen a deficiencia de nutrientes como la vitamina D. Por otro lado, se sugiere que la vitamina D tiene acción antiinflamatoria y antioxidante. Objetivo: evaluar la prevalencia de hipovitaminosis D y la asociación entre los niveles séricos de 25 hidroxivitamina D con los marcadores de estrés oxidativo e inflamación en pacientes con fibrosis quística. Método: estudio transversal realizado con 48 pacientes con fibrosis quística, niños, adolescentes y adultos, de la región nordeste de Brasil. Se realizó una extracción de sangre para el análisis de 25-hidroxivitamina D, calcio, hormona paratiroidea, proceso inflamatorio (proteína C-reactiva [PCR] y alfa-1-glucoproteína ácida-A1 [A1GPA]) y estrés oxidativo (malondialdehído [MDA] y capacidad antioxidante total [CAOT]). El análisisestadístico se realizó utilizando el “Paquete Estadístico para las Ciencias Sociales”, adoptando un nivel de significancia de p < 0,05. Resultados: se encontró insuficiencia/deficiencia de vitamina D en el 64,6 % de los pacientes. Después de un análisis de regresión lineal múltiple, la MDA mostró una asociación inversa con los valores sanguíneos de 25-hidroxivitamina D (p < 0,05) condicionado a la presencia de marcadores de proceso inflamatorio; cuando solo se evalúa el estrés oxidativo, esta asociación desaparece. Conclusión: en conclusión, hubo una alta prevalencia de hipovitaminosis D, con niveles de 25(OH)D asociados a mayor estrés oxidativo cuando se combina con marcadores inflamatorios. La mejora de los niveles de vitamina D puede ser una alternativa para reducir el daño causado por el exceso de estrés oxidativo y la inflamación en pacientes con FQ. (AU)

Guia Prático de Atualização no tratamento da exacerbação de asma na criança e no adolescente ­ Posicionamento conjunto da Associação Brasileira de Alergia e Imunologia e Sociedade Brasileira de Pediatria / Practical Update Guide on the treatment of asthma exacerbation in children and adolescents ­ Joint position of the Brazilian Association of Allergy and Immunology and the Brazilian Society of Pediatrics

Exacerbação aguda de asma é uma condição frequente na criança e no adolescente e uma das causas mais comuns de procura aos pronto atendimentos e de internações. Pode ocorrer em pacientes que ainda não foram diagnosticados como asmáticos, e mesmo naqueles cujo controle da doença não se encontre adequado. Reconhecer a exacerbação e iniciar seu tratamento desde o domicílio até o adequado manejo inicial em ambiente hospitalar é fundamental para evitar sua evolução para complicações que coloquem o paciente em risco de vida. O tratamento compreende o reconhecimento e tratamento da hipoxemia, da obstrução e do processo inflamatório, além de fornecer orientações na alta hospitalar e encaminhamentos para continuidade do tratamento.

Acute exacerbation of asthma is a frequent condition in children and adolescents and one of the most common causes of seeking emergency care and hospitalization. It can occur in patients who have not yet been diagnosed with asthma, and even in those whose disease control is not adequate. Recognizing the exacerbation and starting its treatment from home until proper initial management in a hospital environment is essential to avoid its evolution to complications that put the patient at risk of life. Treatment comprises the recognition and treatment of hypoxemia, obstruction, and the inflammatory process, in addition to providing guidance at hospital discharge and referrals for continued treatment.

Peak inspiratory flow in children and adolescents with asthma using dry powder inhalers: a cross-sectional study.

OBJECTIVE: To measure peak inspiratory flow (PIF) and assess dynamic lung function in children and adolescents with asthma, as well as to determine the association of PIF with dynamic lung function and clinical variables. METHODS: This was a cross-sectional study of children and adolescents with asthma using dry powder inhalers (DPIs) regularly. The control group included sex-, age-, weight-, and height-matched individuals without lung disease. Socioeconomic and clinical variables were collected. PIF and dynamic lung function variables were obtained with a specific device. Between-group comparisons were made with the Student's t-test and ANOVA. Multiple linear regression analysis was performed, and Pearson's correlation coefficients were calculated to assess associations between PIF and the other variables. RESULTS: A total of 88 individuals (44 asthma patients and 44 controls) participated in the study. PIF and respiratory muscle strength (S-index) values were lower in the asthma patients than in the controls. PIF correlated positively with age, weight, height, and S-index in the asthma group. After controlling for height, we found an increase of 0.05 units in PIF associated with an increase of 1 unit in the S-index in the asthma group. CONCLUSIONS: PIF appears to be lower in children and adolescents with asthma than in those without asthma, correlating positively with age, height, weight, and respiratory muscle strength.

RESUMO Objetivo: Analisar o pico de fluxo inspiratório (PFI) e a função pulmonar dinâmica de crianças e adolescentes asmáticos e verificar sua associação com variáveis clínicas. Métodos: Estudo transversal com crianças e adolescentes asmáticos que faziam uso regular de inaladores de pó. O grupo controle foi composto por participantes sem doença pulmonar, pareados por sexo, idade, peso e altura. Foram coletadas variáveis socioeconômicas e clínicas. O PFI e variáveis de função pulmonar dinâmica foram obtidos através de um dispositivo específico. As associações entre os dois grupos foram estudadas utilizando-se o teste t de Student e ANOVA. Realizou-se um modelo de regressão linear múltipla e foram calculados os coeficientes de correlação de Pearson para estimar associações entre o PFI e as demais variáveis. Resultados: Foram incluídos no estudo 88 participantes (44 em cada grupo). Nos asmáticos, os valores do PFI e de força muscular respiratória (S-índex) foram menores que os dos controles. O PFI nos asmáticos apresentou correlações positivas com as variáveis idade, peso, altura e S-índex. Controlando-se a altura, houve um aumento de 0,05 unidades no PFI associado ao aumento de 1 unidade de S-índex nos asmáticos. Conclusões: O PFI é menor em crianças e adolescentes com asma em comparação àqueles sem asma com características antropométricas semelhantes e apresenta correlações positivas com idade, altura, peso e força dos músculos respiratórios.

Perspectivas sobre o uso das diretrizes de desenho instrucional para a simulação na saúde: revisão da literatura / Perspectives on the use of instructional design guidelines for health simulation: a literature review

OBJETIVOS: Este artigo teve dois objetivos principais: apresentar um breve resumo de conceitos cognitivos introdutórios sobre aprendizagem e instrução na simulação, incluindo as diretrizes de desenho instrucional; e oferecer uma visão geral quanto às evidências disponíveis sobre perspectivas instrucionais na efetividade da simulação na saúde, diferentes formatos instrucionais da simulação, fidelidade e local da simulação. MÉTODOS: Uma busca foi realizada nas bases de dados MEDLINE/PubMed, Embase, Cochrane, ERIC, LILACS e SciELO, a partir dos termos "simulação em saúde", "efetividade da simulação", "treinamento", "diretrizes de desenho instrucional", "aprendizagem complexa" e "transferência da aprendizagem" e seus correspondentes em inglês. O início das datas de publicação não foi especificado e a última busca foi conduzida em 19 de setembro de 2017. Todos os artigos em inglês e português foram considerados para inclusão. Artigos específicos foram intencionalmente incluídos em busca de conceitos introdutórios. RESULTADOS: A busca identificou 3.196 artigos nas diferentes bases de dados. Após avaliação preliminar de títulos, resumos e análise de conteúdo, foram selecionados 56 artigos. Adicionalmente, nove artigos clássicos e um livro foram intencionalmente incluídos para a apresentação de conceitos cognitivos sobre aprendizagem e instrução, resultando em 66 referências consultadas em detalhes para esta revisão. CONCLUSÕES: A simulação oferece a oportunidade de aprendizagem ativa para profissionais de saúde ao proporcionar um ambiente de aprendizagem complexa, com integração do conhecimento, habilidades e atitudes. Com potencial de impacto nos diferentes níveis de aprendizagem, comportamento e resultados, especial atenção deve ser dada ao formato instrucional da simulação. Entre as diretrizes de desenho instrucional, destaca-se a autenticidade como um dos elementos de fundamental relevância para a aprendizagem. Outros elementos instrucionais, como complexidade crescente, local do treinamento adequado, debriefing, oportunidade de autoavaliação e outras formas de avaliação, têm também influência positiva e devem ser utilizados no planejamento de diferentes desenhos instrucionais da simulação.

AIMS: This article had two main objectives: to present a brief summary of introductory cognitive concepts on learning and instruction for simulation, including instructional design guidelines; and provide an overview of the current available evidence on the instructional perspectives on healthcare simulation training effectiveness, in particular with regards to simulation formats, fidelity and simulation site. METHODS: We searched for articles at MEDLINE/PubMed, Embase, Cochrane, ERIC, LILACS and SciELO databases, using the keywords "instructional design guidelines", "healthcare simulation", "simulation training", "simulation effectiveness", "complex learning", and "transfer of learning". No specific beginning date of publication was specified and last date of search was September 19th 2017. All articles in English and Portuguese were considered for inclusion with no specific exclusion criteria. A few articles were purposefully selected in search of introductory concepts on learning and instruction. RESULTS: Our search retrieved 3196 articles in the different databases. After preliminary title, abstract and content analysis, we selected 56 articles. Additionally, nine traditional articles and one book were included to present the best available evidence, reviews, reflections and critiques on simulation instructional perspectives, resulting in 66 references consulted in detail for this review. CONCLUSIONS: Simulation offers the opportunity for active learning for health professionals by providing a complex learning environment with integration of knowledge, skills and attitudes. With potential impact on the different levels of learning, behavior and results, special attention should be given to the instructional format of the simulation. Among the instructional design guidelines, authenticity stands out as one of the elements of fundamental relevance for learning. Other instructional elements, such as increasing complexity, proper training location, debriefing, self-assessment opportunity, and other forms of assessment, also have positive influence and should be used in planning different simulation instructional designs.

Chikungunya infection in infants / Infecção por Chikungunya em lactentes

Abstract Introduction: the infection of chikungunya virus presents clinical manifestations variables, particularly in infants in which may present multiple cutaneous manifestations. Description: a case series study was carried out in an analytical character of 14 infants (>28 days to < 2 years old) admitted in a hospital between November 2015 and January 2016 with suspected case of chikungunya, by a specific IgM reactive serology. Patients positive for dengue fever, Zika virus, bacterial infections and other exanthematic diseases were excluded. Fever and cutaneous alterations were the most frequent clinical manifestations in 100% of the cases, followed by irritability (64.3%), vomits and arthralgia/arthritis in 35.7% each. Three children presented alterations in the cerebrospinal fluid compatible to meningitis. Anemia frequency was 85.7%. The median white blood cells count was 7.700/mm3 (2.600 to 20.300/mm3). High levels of aminotransferases were observed in three cases (230 to 450 U/L). Antibiotic therapy was indicated in 64.3% of the cases. Two infants needed opioid derivatives for analgesia while others took acetaminophen and/or dipyrone. Discussion: the study shows evident multi-systemic involvement of chikungunya infection in infants. The treatment is supportive, giving special attention to hydration, analgesia, skin care, and rational use of antibiotic therapy.

Resumo Introdução: a infecção pelo vírus chikungunya apresenta manifestações clínicas variáveis, particularmente em lactentes, nos quais parece haver uma multiplicidade de manifestações cutâneas. Descrição: foi feito um estudo tipo de série de casos de caráter analítico com 14 lactentes (>28 dias a < 2 anos) internados entre novembro de 2015 e janeiro de 2016 como caso suspeito de infecção por chikungunya com sorologia IgM específica reagente. Excluídos pacientes com exame positivo para dengue, Zika vírus, infecção bacteriana e outras doenças exantemáticas. As manifestações clínicas mais frequentes foram febre e alterações cutâneas em 100% dos casos, irritabilidade (64,3%), vômitos e artralgia/artrite em 35,7% cada. Três crianças apresentaram alterações liquóricas compatíveis com meningite. A frequência de anemia foi de 85,7%. A mediana de leucometria foi de 7.700/mm3 (2.600 a 20.300/mm3). Níveis aumentados de aminotransferases foram observados em três casos (230 a 450 U/L). Antibioticoterapia foi indicada em 64,3% dos casos. Dois lactentes necessitaram de derivados de opioides para analgesia fixa, enquanto os demais, paracetamol e/ou dipirona. Discussão: o estudo evidencia envolvimento multisistêmico da infecção por chikungunya em lactentes. O tratamento permanece de suporte, com atenção a hidratação, analgesia, cuidados com a pele e ao uso racional de antibioticoterapia.

Relative frequency, Possible Risk Factors, Viral Codetection Rates, and Seasonality of Respiratory Syncytial Virus Among Children With Lower Respiratory Tract Infection in Northeastern Brazil.

Few studies, each limited to a single major city, have investigated the prevalence and seasonal patterns of different viruses among children with low respiratory tract infections (LRTI) in Northeastern Brazil. The aim of this study was to determine the frequency of respiratory syncytial virus (RSV) and of 7 other viruses in children for LRTI in 4 capitals from this region, and investigate their association with several risk factors, including meteorological data. From April 2012 to March 2013, 507 children, aged up to 24 months and hospitalized with LRTI in one of the participating centers at Aracajú, Salvador, Recife, and Maceió, had a sample of nasopharyngeal aspirate collected and analyzed for the following viruses by reverse-transcription polymerase chain reaction followed by hybridization on low-density microarrays: RSV, influenza, parainfluenza, adenovirus, rhinovirus, metapneumovirus, bocavirus, and coronavirus. The result was positive in 66.5% of cases, RSV was the most common virus (40.2%). Except for rhinovirus (17%), all other virus had frequency rates lower than 6%. Viral coinfections were detected in 13.8% of samples. Possible related risk factors for RSV infection were low age upon entry, attendance of daycare, low gestational age, and low educational level of the father. The relative frequency of viral infections was associated with increasing temperature and decreasing humidity separately, but the results also suggested both associated with increased frequency of RSV. Some of these findings differ from those reported for other regions in Brazil and may be used to guide policies that address LRTI.

Acute asthma management in children: knowledge of the topic among health professionals at teaching hospitals in the city of Recife, Brazil.

OBJECTIVE: Knowledge of acute asthma management in children is a subject that has rarely been explored. The objective of this study was to assess the level of such knowledge among health professionals in the city of Recife, Brazil. METHODS: This was a cross-sectional survey involving 27 pediatricians and 7 nurses, all with at least two years of professional experience, at two large pediatric teaching hospitals in Recife. The participants completed a self-administered multiple-choice questionnaire. RESULTS: The pediatricians and nurses all possessed insufficient knowledge regarding the use of metered dose inhalers, nebulization, and types/doses of medications, as well as techniques for decontamination and disinfection of the equipment. CONCLUSIONS: Insufficient knowledge of acute asthma management in children can lead to less effective treatment in hospitals such as those evaluated here. Educational programs should be developed in order to minimize this problem.

Low income as a protective factor against asthma in children and adolescents treated via the Brazilian Unified Health System.

OBJECTIVE: To analyze the role that low income plays in the development of asthma in children and adolescents. METHODS: A case-control study using a questionnaire. RESULTS: A total of 687 participants were studied at a tertiary hospital via the Brazilian Unified Health System. Ages ranged from 5 to 15 years, and 54.7% of the participants were male. Nearly half of the individuals (49.1%) lived in the metropolitan area of the city of Recife, and the remainder lived in the countryside. Most (98.1%) lived in concrete houses or apartments, with a mean of 5.7 rooms and 4.8 occupants per residence. Mean maternal level of education was 6.8 years of schooling. The median monthly per capita income was R$ 103.75 (Brazilian reals). The sample was stratified according to cut-off points related to the national minimum wage (R$350.00): <25% of minimum wage = very low income (39% of the sample); <50% of minimum wage = low income (37.3% of the sample); and > or =50% of minimum wage = satisfactory income (23.7% of the sample). There was no association between poverty and development of asthma. CONCLUSIONS: Poverty is not protective against asthma in children and adolescents treated via the Brazilian Unified Health System, as we might suppose based on the hygiene hypothesis. However, cohort studies are needed in order to confirm these findings.

Baixa renda como fator de proteção contra asma em crianças e adolescentes usuários do Sistema Único de Saúde / Low income as a protective factor against asthma in children and adolescents treated via the Brazilian Unified Health System

OBJETIVO: O estudo visou analisar o papel da baixa renda como fator de risco para o desenvolvimento de asma em crianças e adolescentes. MÉTODOS: Estudo de caso-controle com questionário. RESULTADOS: Foram estudados 687 participantes, de 5 a 15 anos de idade, usuários do Sistema Único de Saúde, em um hospital terciário, sendo 54,7 por cento masculinos. Quase metade (49,1 por cento) residia na zona metropolitana do Recife e o restante no interior. Moravam em casa de alvenaria 98,1 por cento, com média de 5,7 cômodos e 4,8 moradores. Suas mães estudaram em média 6,8 anos. A mediana da renda mensal per capita foi de R$ 103,75. Baseando-se na renda mensal per capita inferior a 25 e 50 por cento do salário mínimo, classificou-se a amostra em muito baixa renda, baixa renda e renda satisfatória, cujos percentuais foram, respectivamente: 39, 37,3 e 23,7. Não se observou associação entre baixa renda e desenvolvimento de asma. CONCLUSÕES: A baixa renda não exerce, em crianças e adolescentes usuários do Sistema Único de Saúde do nordeste do Brasil, efeito protetor no surgimento de asma, como poderia se supor, baseando-se na teoria da higiene. Todavia, estudos de coorte são necessários para confirmar estes achados.

OBJECTIVE: To analyze the role that low income plays in the development of asthma in children and adolescents. METHODS: A case-control study using a questionnaire. RESULTS: A total of 687 participants were studied at a tertiary hospital via the Brazilian Unified Health System. Ages ranged from 5 to 15 years, and 54.7 percent of the participants were male. Nearly half of the individuals (49.1 percent) lived in the metropolitan area of the city of Recife, and the remainder lived in the countryside. Most (98.1 percent) lived in concrete houses or apartments, with a mean of 5.7 rooms and 4.8 occupants per residence. Mean maternal level of education was 6.8 years of schooling. The median monthly per capita income was R$ 103.75 (Brazilian reals). The sample was stratified according to cut-off points related to the national minimum wage (R$350.00): <25 percent of minimum wage = very low income (39 percent of the sample); <50 percent of minimum wage = low income (37.3 percent of the sample); and >50 percent of minimum wage = satisfactory income (23.7 percent of the sample). There was no association between poverty and development of asthma. CONCLUSIONS: Poverty is not protective against asthma in children and adolescents treated via the Brazilian Unified Health System, as we might suppose based on the hygiene hypothesis. However, cohort studies are needed in order to confirm these findings.
