Arterial stiffness contributes to heart failure and is decreased by angiotensin receptor blockers (ARBs). This cross-sectional study aimed to assess associations of lung function and ARB with arterial stiffness in patients with chronic heart failure. 354 outpatients (168 males; 186 females; 68.2 ± 7.2 years old) with chronic heart failure were evaluated. Lung function parameters, including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and FEV1to FVC ratio (FEV1/FVC), were assessed. The cardio-ankle vascular index (CAVI) was used to estimate arterial stiffness. Unadjusted correlation analyses revealed a positive association of CAVI with ARB but not ACEI, and a negative correlation with FEV1(r=-0.2987,p<0.0001). Multiple stepwise regression analyses showed that ARB and FEV1 (p<0.0001) were independent predicting factors for CAVI. These findings suggest that reduced pulmonary function is associated with increased CAVI. Pulmonary function protection could be used to improve the prognosis in heart failure, but additional studies are necessary.

ObjectivePrevious studies have reported inverse associations between socioeconomic status (SES) and lung function, but less is known about whether pulmonary function is affected by SES changes. We aimed to describe the relationship of changes of SES between childhood and adulthood with pulmonary function.DesignCross-sectional study.ParticipantsThe study sample included 4104 men and women, aged 45–69 years, residents of Krakow, participating in the Polish part of the Health, Alcohol and Psychosocial Factors in Eastern Europe Project.Main outcomeForced expiratory volume (FEV1) and forced vital capacity (FVC) were assessed by the standardised spirometry procedure. Participants were classified into three categories of SES (low, moderate or high) based on information on parent’s education, housing standard during childhood, own education, employment status, household amenities and financial status.ResultsThe adjusted difference in mean FVC between persons with low and high adulthood SES was 100 mL (p=0.005) in men and 100 mL (p<0.001) in women; the differences in mean FEV1were 103 mL (p<0.001) and 80 mL (p<0.001), respectively. Upward social mobility and moderate or high SES at both childhood and adulthood were related to significantly higher FEV1and FVC compared with low SES at both childhood and adulthood or downward social mobility.ConclusionsLow SES over a life course was associated with the lowest lung function. Downward social mobility was associated with a poorer pulmonary function, while upward mobility or life course and moderate or high SES were associated with a better pulmonary function.

AbstractObjectiveA limited but growing body of evidence supports a significant role of antioxidant and anti-inflammatory micronutrients in pulmonary health. We investigated the associations of dietary and supplemental intakes of vitamins A, C, E and D, Se and n-3 PUFA with pulmonary function in a population-based study.DesignPopulation-based, cross-sectional study and data analysis of fruits and vegetables, dairy products and fish, vitamins A, C, E and D, Se and n-3 PUFA supplemental intakes, pulmonary risk factors and spirometry.SubjectsChinese older adults (n 2478) aged 55 years and above in the Singapore Longitudinal Ageing Studies.ResultsIn multiple regression models that controlled simultaneously for gender, age, height, smoking, occupational exposure and history of asthma/chronic obstructive pulmonary disease, BMI, physical activity, and in the presence of other nutrient variables, daily supplementary vitamins A/C/E (b = 0·044, se = 0·022, P = 0·04), dietary fish intake at least thrice weekly (b = 0·058, se = 0·016, P < 0·0001) and daily supplementary n-3 PUFA (b = 0·068, se = 0·032, P = 0·034) were individually associated with forced expiratory volume in the first second. Supplemental n-3 PUFA was also positively associated with forced vital capacity (b = 0·091, se = 0·045, P = 0·045). No significant association with daily dairy product intake, vitamin D or Se supplements was observed.ConclusionsThe findings support the roles of antioxidant vitamins and n-3 PUFA in the pulmonary health of older persons.

AimThe aim of this study was to critically analyse and describe gender differences related to self-care among patients with chronic heart failure (HF).Methods and resultsA monocentric real-world cohort of 346 patients with chronic HF in follow-up was used for this cross-sectional study. We report data related to the cohort’s demographic and clinical characteristics. Self-care was assessed using the Self-Care of Heart Failure Index before patients’ discharge. After bivariate analysis, logistical regression models were used to describe the relationship between gender, self-care behaviours and self-care confidence. While men were found to have more than quadruple the risk of poor self-care than women (OR 4.596; 95% CI 1.075 to 19.650), men were also found to be approximately 60% more likely to have adequate self-care confidence than women (OR 0.412; 95% CI 0.104 to 0.962). Considering that self-care confidence is described as a positive predictor of behaviours, our results suggest a paradox. It is possible that the patient–caregiver relationship mediates the effect of confidence on behaviours. Overall, adequate levels of self-care behaviours are a current issue, ranging 7.6%–18.0%.ConclusionThis study sets the stage for future research where elements of the patient–caregiver relationship ought to be considered to inform the planning of appropriate educational interventions. We recommend routinely measuring patients’ self-care behaviours to guide their follow-up and as a basis for any changes in their daily life behaviours.

ObjectivesTo describe the epidemiology of lung function in Australian children aged 11–12 years and their parents, and explore the degree of intergenerational concordance.DesignCross-sectional study (the Child Health CheckPoint) nested in the Longitudinal Study of Australian Children (LSAC).SettingAssessment centres in seven Australian cities and eight regional towns, February 2015 to March 2016. Families unable to attend a clinic appointment were offered a home visit during the same period.Participants1874 families (53% of all eligible) participated in the study. Lung function data were available for 1759 children aged 11–12 years and 1774 parents (1668 biological pairs).Outcome measuresParticipants completed spirometry with measures including forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and mid expiratory flow (MEF), converted to z-scores using Global Lung Initiative equations. Parent–child concordance was assessed using Pearson’s correlation coefficients and multivariable linear regression models. Survey weights and methods accounted for LSAC’s complex sampling, stratification and clustering within postcodes.ResultsAll lung function measures followed approximately normal distributions. Mean (SD) for FEV1, FVC and MEF z-scores in children were 0.33 (1.07), 0.83 (1.14) and −0.48 (1.09), respectively. Mean (SD) in parents were 0.28 (1.10), 0.85 (1.15) and −0.45 (1.10), respectively. Parent FEV1, FVC and MEF were associated with child lung function with significant positive correlation coefficients (0.22, 95% CI 0.17 to 0.26; 0.24, 95% CI 0.20 to 0.29; and 0.24, 95% CI 0.20 to 0.29, respectively).ConclusionsMean lung volumes were larger but with smaller airway size than international standards for both parents and children in this population sample. Modest associations between parent and child lung function highlight the potential for better identification of ‘at risk’ populations. Therefore, these findings may aid the development of health policy that aims to prevent the onset or limit the progression of lung disease.

ABSTRACT Objective: To evaluate the association of body mass index (BMI) and albumin with pulmonary function in cystic fibrosis (CF) pediatric subjects. Methods: This is a cross-sectional study with clinically stable CF’s subjects. Clinical (pulmonary function) and nutritional evaluation (body mass index and albumin) were performed. Univariate analysis was performed using simple linear correlations. Regression analysis was performed using an exit level of p<0.05. Results: Seventy-eight CF’s subjects (mean age 12.8±3.8 years) with mean albumin 4.2±0.4 mg/dL, predicted forced expiratory volume in 1 second (FEV1%) 80.8±22.6 and BMI median percentile 51.2 (1.3-97.7). In the multiple regression models, albumin, age and BMI percentile were associated with pulmonary function. Subjects with lower than 25 BMI percentile had 12.2% lower FEV1%. An albumin increase of 0.1 mg was associated with 2.7% increase in predicted FEV1%, and one year increase in age was associated with reduction in 1.2% of predicted FEV1%. Conclusions: BMI percentile, albumin and age were independently associated with predicted FEV1% in a tertiary referral hospital.

9591 Background: Bleomycin has been established as a pulmonary toxin, but the risk for toxicity in survivors of childhood cancer is poorly characterized. Methods: We conducted a cross-sectional study of lung function in survivors of childhood Hodgkin lymphoma and germ cell tumor treated with bleomycin at our institution between 1997 and 2010. We assessed their most recent post-therapy pulmonary function test (PFT). Spirometry and lung volumes were categorized as normal, restrictive, obstructive or mixed. Diffusing capacity of carbon monoxide (DLCO) was categorized as normal or abnormal. Results: 195 patients were treated with bleomycin. Ten died of non-pulmonary causes. Of 185 survivors, 143 (77%) had complete data available for analysis. Median cumulative bleomycin dose was 60U/m2 (IQR 30-60). Three patients (2%) had a history of acute bleomycin toxicity. PFTs were performed a median of 2.3 years (IQR 1.4-4.9) from completion of therapy. Spirometry was abnormal in 58 patients (41%); of whom 5 (9%) had respiratory symptoms. 42 (70%) had obstructive, 11 (18%) restrictive and 5 (9%) mixed ventilatory defects. Abnormalities were mild in 53 (91%), moderate in 3 (5%) and severe in 2 (4%). DLCO was abnormal in 27 patients, 26 (96%) of whom had mildly reduced DLCO and were asymptomatic. Univariate analysis did not demonstrate a significant association between gender, smoking, lung metastases, lung radiation, chemotherapy regimen, or autologous transplant and abnormal lung function. Disease relapse was associated with abnormal lung function (p=0.01). Smoking (p=0.04) and relapse (p=0.03) were associated with abnormal DLCO. The odds ratio of developing abnormal spirometry for each 1unit/m2 increase in bleomycin was 1.01 (95% CI 1.00-1.02, p=0.07). Conclusions: Childhood cancer survivors treated with bleomycin frequently have evidence of asymptomatic abnormalities on PFT. The current recommendation for pulmonary function testing in childhood cancer survivors appears justified.

Introduction: Cystic fibrosis (CF) is a serious genetic life-shortening disease. Quality of life (QoL) measurement related to CF children is a relatively new field of research, which includes the patient’s perspective in research and clinical practice. Objectives: This study aimed to evaluate the QoL in children with CF and its association with FEV1 (forced expiratory volume in 1 second). Patients and Methods: This cross-sectional study was carried out on 7-14 years old children with CF attending children’s medical center from March 2017 to March 2018. Throat swab cultures and spirometry evaluation was performed for all patients. FEV1 was determined and the 6-min walk test (6MWT) was conducted. The patient’s psychological status was assessed using the Persian version of pediatric QoL inventory. ANOVA, t test, and chisquare tests were used for data analysis. Results: Seventy-six subjects with the mean age of 10.49±3.18 years were studied since 59% of them (n=44) were boys. The mean total QoL was 65.34±17.73. Patients with lower pulmonary function had a lower QoL. There was a significant association between FEV1 and school and emotional functioning (P=0.005 and P=0.002, respectively). A significant association was found between SPO2 (peripheral capillary oxygen saturation) reduction after 6MWT and FEV1 decline (P=0.001). Additionally, a significant association was detected between FEV1 and the distance walked during 6MWT (P=0.030). Conclusion: Regarding the association between pulmonary function and QoL in CF patients and lower QoL score in our study, the importance of assessing pulmonary function in these patients should not be neglected.

Background: Studies have associated HIV with an increased risk of obstructive lung disease (OLD).Objectives: We aimed to identify the predictive factors for impaired lung function in an urban, African, HIV-positive population.Method: A cross-sectional study was performed in Johannesburg, South Africa, from July 2016 to November 2017. A questionnaire was administered and pre- and post-bronchodilator spirometry conducted. The predictors investigated included age, sex, antiretroviral treatment (ART) duration, body mass index, history of tuberculosis (TB) or pneumonia, occupational exposure, environmental exposure, smoking and symptoms of OLD (cough, wheeze, mucus and dyspnoea). Impaired lung function was defined as a forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) ratio of 0.70, or below the 20th percentile of normal.Results: The 98 ART-naïve participants (mean age = 34.0, standard deviation [s.d.] = 8.2), 85 participants on first-line ART (mean age = 36.9, s.d. = 6.6) and 189 participants on second-line ART (mean age = 43.5, s.d. = 7.9) were predominantly female (65.6%). Of the participants, 64 (17.2%) had impaired lung function and 308 had normal lung function. Linear regression identified age (β = –0.003, P 0.01), male sex (β = –0.016, P = 0.03) and history of TB or pneumonia (β = –0.024, P 0.01) as independent predictors of a lower FEV1/FVC ratio. Following logistic regression, only a history of TB or pneumonia (odds ratio = 2.58, 95% confidence interval = 1.47–4.52) was significantly related to impaired lung function (area under the receiver operating characteristic curve = 0.64).Conclusion: Our data show that a history of TB or pneumonia predicts impaired lung function. In order to improve timely access to spirometry, clinicians should be alert to the possibility of impaired lung function in people with a history of TB or pneumonia.

AIM: The objective of the study was to determine chronic respiratory symptoms and lung function of farmers. METHODS: The study was conducted in Utu Village, Tabanan, Bali with 84 subjects. This research was observational analytic cross sectional study. RESULTS: Three dominant chronic respiratory symptoms in farmers were coughing (15.1%), dyspnea (13.1%), and phlegm (13.1%). Average values of forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and FEV1/FVC were 83.75 ± 34.42, respectively, 81.62 ± 34.30 and 104.90 ± 13.90, respectively. Cough was dominant experiencing by smokers (p = 0.008). Mean of FEV1% prediction and FVC% prediction value was lower in passive smoker group than no smoker group (p = 0.005 and p = 0.03). CONCLUSION: Occupational exposure while farming and raising livestock can cause chronic respiratory symptom and lung function decline in farmers and can be influenced by smoking history and secondhand smoke exposure.
