The Impact

Abstract Not so much emphasize in literature and studies, obesity consequences on respiratory function may influence chronic obstructive pulmonary disease COPD and asthma, triggering important healthcare issues. Pulmonary function is a mortality predictor. The largest populational study European Community Respiratory Health Survey shows the impact of overweight and obesity on pulmonary function by decreasing forced expiratory volume in first second FEV1 and forced vital capacity FVC. By the contrary, weight loss is decreasing both. Inflammatory and mechanical mechanisms should be considered in lung function impairment, as a consequence of obesity. Important aspect, lifestyle, will consider tobacco, physical activity, diet. Adopting a healthy lifestyle with a Mediterranean Diet MD will preserve a good pulmonary function on long term. We detailed below specific dietary recommendations, favorable nutrients or foods to be avoided. In conclusion comprehensive lifestyle interventions should become populational based interventions for a better prevention for pulmonary diseases and NCD’s and finally for a better health status.

The Life Course

RationaleWe aimed to identify differentially methylated regions (DMRs) in cord blood DNA associated with childhood lung function, asthma and chronic obstructive pulmonary disease (COPD) across the life course.MethodsWe meta-analysed epigenome-wide data of 1688 children from five cohorts to identify cord blood DMRs and their annotated genes, in relation to forced expiratory volume in 1 s (FEV1), FEV1/forced vital capacity (FVC) ratio and forced expiratory flow at 75% of FVC at ages 7–13 years. Identified DMRs were explored for associations with childhood asthma, adult lung function and COPD, gene expression and involvement in biological processes.ResultsWe identified 59 DMRs associated with childhood lung function, of which 18 were associated with childhood asthma and nine with COPD in adulthood. Genes annotated to the top 10 identified DMRs were HOXA5, PAOX, LINC00602, ABCA7, PER3, CLCA1, VENTX, NUDT12, PTPRN2 and TCL1A. Differential gene expression in blood was observed for 32 DMRs in childhood and 18 in adulthood. Genes related with 16 identified DMRs were associated with respiratory developmental or pathogenic pathways.InterpretationOur findings suggest that the epigenetic status of the newborn affects respiratory health and disease across the life course.

The Impact

This study aimed at investigating whether providing feedback on physical activity (PA) levels to patients with chronic obstructive pulmonary disease (COPD) is feasible and enhances daily PA during pulmonary rehabilitation (PR). Patients with COPD participated in a 12-week PR program. Daily PA was measured using activity monitors on weeks 1, 7, and 12, and feedback was given in the following weeks on the number of steps, time spent in sedentary, light, and moderate-to-vigorous intensity activities, and time spent standing, sitting, and lying. Compliance with PA monitoring was collected. Two focus groups were conducted to obtain patients’ perspectives on the use of activity monitors and on the feedback given. Differences in PA data were also assessed. Sixteen patients (65.63 ± 10.57 years; forced expiratory volume in one second (FEV1) 70.31 ± 22.74% predicted) completed the study. From those, only eleven participants used the activity monitors during all monitoring days. Participants identified several problems regarding the use of activity monitors and monitoring duration. Daily steps (  p = 0.026) and standing time (  p = 0.030) were improved from week 1 to week 7; however, the former declined from week 7 to week 12. Findings suggest that using feedback to improve PA during PR is feasible and results in improved daily steps and standing time on week 7. The subsequent decline suggests that additional strategies may be needed to stimulate/maintain PA improvements. Further research with more robust designs is needed to investigate the impact of feedback on patients’ daily PA.

Objective: To investigate the clinical effects of the use of portable pulmonary function tester in patients with stable Chronic Obstructive Pulmonary Disease (COPD). Methods: A total of 80 patients with stable COPD were enrolled in our hospital from March 2018 to March 2019. They were divided into two groups according to different treatment methods. The comparison group was used for routine pulmonary function training, and the intervention group was trained for Portable Pulmonary Function Training and Test Device (PPFTTD). Comparison was made of forced expiratory volume in one second/forced vital capacity (FEV1/FVC), measured/predicted value of the first second forced expiratory volume (FEV1 measured/predicted value), measured/predicted value of maximal voluntary ventilation per minute between the two groups. Quality of life (QOL) scores such as daily living ability, social activity, depressive psychological symptoms, and anxiety psychological symptoms were measured. Results: The FEV1/FVC value, measured/predicted value of FEV1 and MVV of intervention group were higher than those in the comparison group ([Formula: see text]). QOL scores, such as daily living ability, social activity, depression psychological symptoms, and anxiety psychological symptoms in the intervention group, were lower than those in the comparison group ([Formula: see text]). Conclusion: In the treatment of stable COPD, the use of portable pulmonary function tester is significant, and it should be widely promoted and applied in clinical practice.

SETTING: Multicentre retrospective study in South Korea.OBJECTIVE: To longitudinally evaluate changes in lung volume and diffusing capacity for carbon monoxide (DLCO) with forced expiratory volume in 1 sec (FEV1).DESIGN: A total of 155 patients with chronic obstructive pulmonary disease (COPD), whose pulmonary function parameters were measured annually for 5 years, were selected from a prospective cohort in South Korea. A random coefficients model was used to estimate mean annual FEV1, lung volume parameter and DLCO change rates.RESULTS: Patients were classified into four groups based on baseline DLCO and residual volume/total lung capacity (RV/TLC) measurements. The annual FEV1 decline rate was greater in patients with low DLCO than in those with normal DLCO, with the greatest decline occurring in patients with low DLCO and normal RV/TLC. RV and RV/TLC declined in patients with high RV/TLC, whereas these increased in patients with normal RV/TLC. DLCO decreased longitudinally in all four groups, with the greatest decline occurring in patients with normal DLCO and normal RV/TLC.CONCLUSIONS: Different subgroups of patients with COPD exhibited distinctive pulmonary function change patterns. Baseline DLCO and RV/TLC may be used as physiological markers to predict long-term changes in pulmonary function.

Objective This study was performed to evaluate the effect of sex on bronchial parameters and the predicted forced expiratory volume in 1 s expressed as a percentage of the forced vital capacity (FEV1% pred) on pulmonary function testing. Methods The data of 359 patients with chronic obstructive pulmonary disease (COPD) with available FEV1% pred and computed tomography (CT) images were retrospectively reviewed. FACT-Digital lung TM software (DeXin, Xi’an, China) was used to perform fully automated three-dimensional CT quantitative measurements of the bronchi. Generation 5 to 7 bronchi were measured, and the parameters analyzed were the lumen diameter (LD), wall thickness (WT), lumen area (LA), and WA% [WA / (WA + LA) × 100%]. Results In the smoking, smoking cessation, and nonsmoking groups, women had a significantly larger WA% and smaller LD, WT, and LA than men. The FEV1% pred was significantly lower in women than men in the smoking and smoking cessation groups. The FEV1% pred was significantly higher in women than men in the nonsmoking group. Conclusion Sex-related differences may partially explain why smoking women experience more severe pulmonary function impairment than men among patients with COPD.

The Right

During coronary angiography in 24 chronic smokers with coronary heart disease, cardiac function measurements were taken and correlated with respiratory function tests. Fourteen patients had evidence of chronic obstructive pulmonary disease. Cardiac output had a direct correlation with vital capacity, forced vital capacity [FVC], forced expiratory volume in 1 s [FEV1], and velocity at 25% of FVC [V [max] 25]. Pulmonary artery resistance was inversely correlated with FEV1/FVC, while pulmonary artery oxygen saturation weakly correlated with FEV1 and V [max] 25. The pulmonary artery pressure had a weak correlation with the pulmonary artery resistance and an intermediate correlation with the right atrium and the right ventricular pressures. Early diagnosis and therapy of chronic obstructive pulmonary disease in smokers may be possible without using invasive methods

Background: Exposures to water-damaged homes/buildings has been linked to deficits in respiratory health. However, accurately quantifying this linkage has been difficult because of the methods used to assess water damage and respiratory health. Purpose: The goal of this analysis was to determine the correlation between the water-damage, as defined by the Environmental Relative Moldiness Index (ERMI) value in an asthmatic child’s home, and the child’s pulmonary function measured by spirometry, “forced expiratory volume in one second, percent predicted” or FEV1%. Methods: This analysis utilized data obtained from the “Heads-off Environmental Asthma in Louisiana” (HEAL) study. The children (n= 109), 6 to 12 years of age, who had completed at least one spirometry evaluation and a dust sample collected for ERMI analysis from the home at approximately the same time as the spirometry testing, were included in the analysis. Statistical evaluation of the correlation between ERMI values and FEV1% was performed using the Spearman’s Rank Correlation analysis. The relationship between ERMI values and FEV1% was performed using B-spline regression. Results: The average ERMI value in the HEAL study homes was 7.3. For homes with ERMI values between 2.5 and 15, there was a significant inverse correlation with the child’s lung function or FEV1% measurement (Spearman’s rho -0.23; p= 0.03), i.e. as the ERMI value increased, the FEV1% value decreased. Conclusions: Measures of water-damage (the ERMI) and clinical assessments of lung function (FEV1%) provided a quantitative assessment of the impact of water-damaged home exposures on children’s respiratory health.

The Impact

Respiratory health is a focus of interdisciplinary studies involving urban planning and public health. Studies have noted that urban built environments have impacts on respiratory health by influencing air quality and human behavior such as physical activity. The aim of this paper was to explore the impact of urban built environments on respiratory health, taking chronic obstructive pulmonary disease (COPD) as one of the typical respiratory diseases for study. A cross-sectional study was conducted including all cases (N = 1511) of death from COPD in the high-density Jing’an district of Shanghai from 2001 to 2010. Proxy variables were selected to measure modifiable features of urban built environments within this typical high-density district in Shanghai. A geographically weighted regression (GWR) model was used to explore the effects of the built environment on the mortality of COPD and the geographical variation in the effects. This study found that land use mix, building width-height ratio, frontal area density, and arterial road density were significantly correlated to the mortality of COPD in high-density urban area. By identifying built environment elements adjustable by urban planning and public policy, this study proposes corresponding environmental intervention for respiratory health.
