Abstract

Introduction Previous population-based studies, mainly from high-income countries, have shown that a higher forced vital capacity (FVC) is associated with a lower risk of developing cardiometabolic diseases. The aim of this study was to assess the longitudinal association between spirometry measures and the onset of cardiometabolic diseases across sites in low-income, middle-income and high-income countries.Methods The study population comprised 5916 individuals from 15 countries participating in the Burden of Obstructive Lung Disease baseline and follow-up assessments. Postbronchodilator forced expiratory volume in 1 s (FEV1), FVC and FEV1/FVC were measured at baseline. Participants who reported having doctor-diagnosed hypertension, diabetes, heart disease and stroke at follow-up but not at baseline were considered new cases of these diseases. The association between lung function and the onset of participant-reported cardiometabolic diseases was assessed in each site using regression models, and estimates were combined using random effects meta-analysis. Models were adjusted for sex, age, smoking, body mass index and educational level.Results Participants with greater per cent predicted FVC were less likely to have new-onset diabetes (OR per 10%=0.91, 95% CI 0.84 to 0.99), heart disease (OR per 10%=0.86, 95% CI 0.80 to 0.92) and stroke (OR per 10%=0.81, 95% CI 0.73 to 0.89) during the follow-up period (mean±SD 9.5±3.6 years). A greater percentage of FEV1 was associated with a lower risk of onset of heart disease and stroke. No significant association was found between FEV1/FVC and onset of reported cardiometabolic diseases, except for a higher risk of diabetes (OR per 10%=1.21, 95% CI 1.08 to 1.35) in participants with higher FEV1/FVC.Conclusions The findings of this study suggest that a low FVC is more important than a low FEV1/FVC as a risk factor for developing cardiometabolic diseases. The value of including FVC in risk score models to improve their precision in predicting the onset of cardiometabolic diseases should be explored.

Abstract

Summary: Background: Chronic cough is a common respiratory symptom with an impact on daily activities and quality of life. Global prevalence data are scarce and derive mainly from European and Asian countries and studies with outcomes other than chronic cough. In this study, we aimed to estimate the prevalence of chronic cough across a large number of study sites as well as to identify its main risk factors using a standardised protocol and definition. Methods: We analysed cross-sectional data from 33,983 adults (≥40 years), recruited between Jan 2, 2003 and Dec 26, 2016, in 41 sites (34 countries) from the Burden of Obstructive Lung Disease (BOLD) study. We estimated the prevalence of chronic cough for each site accounting for sampling design. To identify risk factors, we conducted multivariable logistic regression analysis within each site and then pooled estimates using random-effects meta-analysis. We also calculated the population attributable risk (PAR) associated with each of the identifed risk factors. Findings: The prevalence of chronic cough varied from 3% in India (rural Pune) to 24% in the United States of America (Lexington,KY). Chronic cough was more common among females, both current and passive smokers, those working in a dusty job, those with a history of tuberculosis, those who were obese, those with a low level of education and those with hypertension or airflow limitation. The most influential risk factors were current smoking and working in a dusty job. Interpretation: Our findings suggested that the prevalence of chronic cough varies widely across sites in different world regions. Cigarette smoking and exposure to dust in the workplace are its major risk factors. Funding: Wellcome Trust.

Abstract

We present the results from an exploratory study that aimed to measure teachers' specialized knowledge in early mathematics during a pilot of an educational intervention using the Foundational Mathematical Knowledge for Teaching (FMKT) survey. The survey was administered to 323 teachers in the Kyrgyz Republic in 2021. We delve into survey results at two timepoints (pre- and post-intervention) to showcase the areas in which the intervention was successful and identify ongoing challenges in teacher knowledge. We found that the FMKT provided detailed, specific information on teacher learning and is an example of one way to center teacher knowledge in an instructional intervention.

Abstract

Introduction: The purpose of the study was to establish spirometric reference values for a Central Asian population of highlanders and lowlanders.Methods: Spirometries from a population-based cross-sectional study performed in 2013 in rural areas of Kyrgyzstan were analyzed. Using multivariable linear regression, Global Lung Function Initiative (GLI) equations were fitted separately for men and women, and altitude of residence (700–800 m, 1,900–2,800 m) to data from healthy, never-smoking Kyrgyz adults. The general GLI equation was applied: Predicted value=ea0+a1× ln(Height)+a2× ln(Age)+b1× ln(Age100)+b2× ln(Age100)2+b3× ln(Age100)3 +b4× ln(Age100)4+b5× ln(Age100)5Results: Of 2,784 screened Kyrgyz, 448 healthy, non-smoking highlanders (379 females) and 505 lowlanders (368 females), aged 18–91 years, were included. Predicted FVC in Kyrgyz fit best with GLI “North-East Asians,” predicted FEV1 fit best with GLI “Other/Mixed.” Predicted FEV1/FVC was lower than that of all GLI categories. Age- and sex-adjusted mean FVC and FEV1 were higher in highlanders (+0.138l, +0.132l) than in lowlanders (P < 0.001, all comparisons), but FEV1/FVC was similar.Conclusion: We established prediction equations for an adult Central Asian population indicating that FVC is similar to GLI “North-East Asian” and FEV1/FVC is lower than in all other GLI population categories, consistent with a relatively smaller airway caliber. Central Asian highlanders have significantly greater dynamic lung volumes compared to lowlanders, which may be due to environmental and various other effects.

Abstract

Background: Nearly 25% of adults worldwide are affected by non-alcoholic fatty liver disease (NAFLD). taged changes in the liver from steatosis progress to non-alcoholic steatohepatitis (NASH) and its complicated forms such as fibrosis, cirrhosis, and hepatocellular carcinoma. There are very few data in the literature on the development of NAFLD in conditions of high altitude. There are no data on the state of pro- and anti-inflammatory cytokines in NAFLD in high altitude conditions. Thus, simulating NAFLD on animals in artificial highlands will help find answers to these questions. Aim: to study the features of the course of non-alcoholic fatty liver disease (NAFLD) in experimental animals in artificial high-mountain conditions. Material and methods: The study was carried out on 180 male Wistar rats. 7 groups of experimental animals were formed, which were divided into control and experimental groups. The rats of the control group were on a standard diet. Non-alcoholic fatty liver disease was modeled by keeping animals on a diet (Ackermann et al., 2005) rich in fructose and fat in low and high mountain conditions (in a pressure chamber 6000 m above sea level) for 35 and 70 days. In all groups of animals, the following was determined: the concentration of total bilirubin (TB), the activity of the enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), the level of total cholesterol (TC), low-density lipoprotein cholesterol (LDL), the total protein content in plasma (TP), pro- and anti-inflammatory cytokines. Results: In animals on a diet enriched with fructose and fat, it equally led to the inhibition of the synthetic function of the liver, both in high altitude and in low altitudes. Liver enzyme levels were uncertain. AST levels were high in all major groups, with a similar upward trend at 5 and 10 weeks on the fructose-fortified diet. The greatest shift was observed on the part of ALT in animals under conditions of hypobaric hypoxia, the growth of which was statistically significantly lower than in the low- altitude groups. The opposite picture was observed in pigment metabolism. Indicators of total cholesterol and LDL increased almost twofold in the main high- altitude groups, and were significantly higher than the indicators of low- altitude animals with p

Abstract

AIM: The aim of the study was to study the level of pro- and anti-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α), and interleukin 4 (IL-4), on a model of non-alcoholic fatty liver disease (NAFLD) in experimental animals under conditions of low mountains and hypobaric hypoxia. METHODS: The study was carried out on 180 male Wistar rats, which were divided into control and experimental groups. The rats of the control group were on a standard diet. NAFLD was modeled by keeping animals on a diet (Ackermann et al., 2005) rich in fructose and fat in conditions of low mountains and hypobaric hypoxia (in a pressure chamber 6000 m above sea level) for 35 and 70 days. Total cholesterol (TC) and lipid spectrum, pro- and anti-inflammatory cytokines were determined in all groups of animals. RESULTS: The activity of pro- and anti-inflammatory cytokines in the main group during the rise of animals in the pressure chamber increased statistically significantly on the 35th day in comparison with the low-altitude group by more than 2 times, and on the 70th day of staying at the high-altitude did not have convincing differences from the low-altitude group. The cytokine index (TNF-α/IL-4) of animals in conditions of hypobaric hypoxia on a fructose enriched diet increased by more than 1.5 times after 5 weeks, staying at an altitude for 10 weeks led to a decrease of TNF-α/IL-4 in relation to the low-mountain group, in which the opposite picture was observed - a tendency towards an increase in TNF-α/IL-4. IL-4 and TNF-α _levels were statistically significantly correlated with lipid metabolism disorders. CONCLUSION: NAFLD in animals on a special diet enriched with fructose under conditions of hypobaric hypoxia leads to deeper disturbances in the system of pro- and anti-inflammatory cytokines and the lipid spectrum.

Abstract

Rationale: The Global Burden of Disease program identified smoking and ambient and household air pollution as the main drivers of death and disability from chronic obstructive pulmonary disease (COPD). Objective: To estimate the attributable risk of chronic airflow obstruction (CAO), a quantifiable characteristic of COPD, due to several risk factors. Methods: The Burden of Obstructive Lung Disease study is a cross-sectional study of adults, aged ≥40, in a globally distributed sample of 41 urban and rural sites. Based on data from 28,459 participants, we estimated the prevalence of CAO, defined as a postbronchodilator FEV1-to-FVC ratio less than the lower limit of normal, and the relative risks associated with different risk factors. Local relative risks were estimated using a Bayesian hierarchical model borrowing information from across sites. From these relative risks and the prevalence of risk factors, we estimated local population attributable risks. Measurements and Main Results: The mean prevalence of CAO was 11.2% in men and 8.6% in women. The mean population attributable risk for smoking was 5.1% in men and 2.2% in women. The next most influential risk factors were poor education levels, working in a dusty job for ≥10 years, low body mass index, and a history of tuberculosis. The risk of CAO attributable to the different risk factors varied across sites. Conclusions: Although smoking remains the most important risk factor for CAO, in some areas, poor education, low body mass index, and passive smoking are of greater importance. Dusty occupations and tuberculosis are important risk factors at some sites.

Abstract

Rationale: Evidence supporting the association of chronic obstructive pulmonary disease or airflow obstruction with use of solid fuels is conflicting and inconsistent. Objectives: To assess the association of airflow obstruction with self-reported use of solid fuels for cooking or heating. Methods: We analyzed 18,554 adults from the BOLD (Burden of Obstructive Lung Disease) study, who had provided acceptable post-bronchodilator spirometry measurements, and information on use of solid fuels. The association of airflow obstruction with use of solid fuels for cooking or heating was assessed by sex, within each site, using regression analysis. Estimates were stratified by national income and meta-analyzed. We performed similar analyses for spirometric restriction, chronic cough, and chronic phlegm. Measurements and Main Results: We found no association between airflow obstruction and use of solid fuels for cooking or heating (odds ratio [OR] for men, 1.20 [95% confidence interval (CI), 0.94–1.53]; OR for women, 0.88 [95% CI, 0.67–1.15]). This was true for low-/middle- and high-income sites. Among never-smokers, there was also no evidence of an association of airflow obstruction with use of solid fuels (OR for men, 1.00 [95% CI, 0.57–1.76]; OR for women, 1.00 [95% CI, 0.76–1.32]). Overall, we found no association of spirometric restriction, chronic cough, or chronic phlegm with the use of solid fuels. However, we found that chronic phlegm was more likely to be reported among female never-smokers and those who had been exposed for 20 years or longer. Conclusions: Airflow obstruction assessed from post-bronchodilator spirometry was not associated with use of solid fuels for cooking or heating.

Abstract

Introduction: The purpose of the study was to establish spirometric reference values for a Central Asian population of highlanders and lowlanders. Methods: Spirometries from a population-based cross-sectional study performed in 2013 in rural areas of Kyrgyzstan were analyzed. Using multivariable linear regression, Global Lung Function Initiative (GLI) equations were fitted separately for men and women, and altitude of residence (700-800 m, 1,900-2,800 m) to data from healthy, never-smoking Kyrgyz adults. The general GLI equation was applied: Predicted value = e a 0 + a 1 × ln ( Height ) + a 2 × ln ( Age ) + b 1 × ln ( Age 100 ) + b 2 × ln ( Age 100 ) 2 + b 3 × ln ( Age 100 ) 3 + b 4 × ln ( Age 100 ) 4 + b 5 × ln ( Age 100 ) 5 Results: Of 2,784 screened Kyrgyz, 448 healthy, non-smoking highlanders (379 females) and 505 lowlanders (368 females), aged 18-91 years, were included. Predicted FVC in Kyrgyz fit best with GLI "North-East Asians," predicted FEV1 fit best with GLI "Other/Mixed." Predicted FEV1/FVC was lower than that of all GLI categories. Age- and sex-adjusted mean FVC and FEV1 were higher in highlanders (+0.138l, +0.132l) than in lowlanders (P < 0.001, all comparisons), but FEV1/FVC was similar. Conclusion: We established prediction equations for an adult Central Asian population indicating that FVC is similar to GLI "North-East Asian" and FEV1/FVC is lower than in all other GLI population categories, consistent with a relatively smaller airway caliber. Central Asian highlanders have significantly greater dynamic lung volumes compared to lowlanders, which may be due to environmental and various other effects.
