儿童支气管哮喘与注意缺陷多动障碍的关系及其危险因素

近年来儿童慢性疾病与神经精神疾病的关系及其致病机制已成为儿科领域研究的热点和难点。支气管哮喘(简称哮喘)是儿童期常见的慢性疾病之一,最新基于人群的大样本报道证实哮喘与儿童最常见的神经发育障碍性疾病注意缺陷多动障碍(ADHD)之间关系密切。现就哮喘和ADHD的具体关系及其危险因素最新研究进展进行综述,以期认识二者之间的关系及其危险因素,便于哮喘患儿的长程临床管理。     

Anxiety sensitivity as a mediator of the association between asthma and smoking

Objective: Despite its negative effects, smoking is more common among individuals with asthma compared to those without. Anxiety sensitivity (fear of arousal-related sensations) is associated with both smoking and asthma; however, no research, to date, has examined the interplay between these three factors. Thus, the purpose of the current study was to evaluate the mediating role of anxiety sensitivity in the association between asthma diagnosis and smoking status. Methods: The current study was a secondary analysis of data from three existing datasets of non-smokers and smokers with and without asthma (n?=?433; 56.3% female, M_age?=?34.01 years, SD?=?13.9). Participants provided information on their asthma diagnosis status and smoking status and completed self-report measures. Results: As hypothesized, after controlling for gender, race and age, there was a significant indirect effect of asthma diagnosis on smoking status through anxiety sensitivity (95% CI?=?0.07–0.48). Conclusions: These results indicate that the association between asthma diagnosis and smoking status appears to be driven, in part, by anxiety sensitivity and suggest that anxiety sensitivity may serve as an important target for prevention and intervention efforts for smokers with asthma.     

呼吸专科护士慢性呼吸疾病管理现状调查

目的调查呼吸专科护士慢性呼吸疾病管理现状,为提高慢性呼吸疾病的管理水平提供参考。方法依据《中国成人慢性呼吸疾病患者护理管理指南》设计调查问卷,对重庆、四川、贵州、陕西、河北、湖北、海南7省市的205名呼吸专科护士进行问卷调查。结果呼吸专科护士慢性呼吸疾病管理总分为(140.72±23.90)分。慢性呼吸疾病管理得分最低的3个条目有评估工具应用、个性化管理计划的实施、慢阻肺随访的次数及指导哮喘患者使用峰流速仪;呼吸专科护士所在单位慢性呼吸疾病管理平台建设均低于50%。结论呼吸专科护士慢性呼吸疾病管理处于中等偏下水平,评估是慢性呼吸疾病管理的薄弱点。需加强呼吸专科护士专业能力培养,规范慢性呼吸疾病全程管理,强化医院平台建设等,提高慢性呼吸疾病的管理水平。     

Pathways in the association between sugar sweetened beverages and child asthma traits in the 2nd year of life: Findings from the BRISA cohort

Studies on the exposure of children to sugar-sweetened beverages (SSBs) at an early age may contribute to better understand the common causes and the temporal order of the relationships between obesity and asthma in early childhood. The objective of this study was to estimate the association between SSB and child asthma traits in the 2nd year of life, modeling direct and indirect pathways mediated by the highest BMI-z of the child and allergic inflammation. Data from the BRISA cohort, São Luís-MA, Brazil (n = 1140), were obtained from the baseline and from the follow-up performed at the 2nd year of life. The main explanatory variable was the calories from added sugars in SSBs as a percentage of the total daily energy intake. The outcome child asthma traits was a latent variable deduced from four indicators: medical diagnosis of asthma, wheezing, emergency visit due to intense wheezing, and medical diagnosis of rhinitis. A high percentage of daily calories from sugars added to SSBs was directly associated with higher values of child asthma traits (standardized coefficient (SC = 0.073; P = .030)). High levels of eosinophils were also directly associated with child asthma traits (SC = 0.118; P = .049). No mediation pathways were observed via greater BMI-z or eosinophil counts. Therefore, early exposure of children to SSB may contribute to increased risk of childhood asthma, preceding the link between sugar consumption and overweight/obesity, not yet evident in children in the first 2 years of life.

Background

Lung ultrasound can accelerate the diagnosis of life-threatening diseases in adults with respiratory symptoms.

Pediatric asthma quality of life questionnaire (PAQLQ): Validation among asthmatic children in Thailand

Quality of life (QoL) is an important consideration among asthma sufferers. The Pediatric Asthma Quality of Life Questionnaire (PAQLQ) is one of the most widely used instruments for measuring health-related QoL in children with asthma. The standardized version of PAQLQ contains 23 questions in three domains, i.e., activity limitation, symptoms and emotional function. The objective of this study was to validate the Thai-translated version of the PAQLQ. The study design consisted of a five-week single cohort study. Patients recorded symptoms, and peak expiratory flow rate (PEFR) each morning and evening during the first and fifth week of the study in asthma diary. At each clinic visit, a trained-interviewer administered the PAQLQ and performed spirometric measurements. Fifty-one children, ages between 7 and 17 yr participated in the study. Scores from the asthma diary were used to classify patients into stable vs. unstable groups. The construct validity of the questionnaire was confirmed in both cross-sectional and longitudinal studies by demonstrating correlations between various PAQLQ domains with clinical asthma parameters (asthma diary, beta-agonist use and PEFR). There was high internal consistency for scores of the three domains (Cronbach's alpha-coefficient = 0.83-0.95). For those with stable asthma, the reliability of PAQLQ was good for the rating scale (intra-class correlation coefficient--ICC = 0.84) and for total score (alpha = 0.97) indicating high reproducibility of the PAQLQ. The significant difference of changes QoL scores between stable and unstable groups was observed in all domains. We conclude that the Thai version of PAQLQ is valid and reliable for implementing in Thai children with asthma.
