Abstract
Bone development and lung function are integral to child and adolescent health. Both influence an individual's overall well-being and potentially affect long-term health. Utilizing a comprehensive dataset from the National Health and Nutrition Examination Survey, this study aims to elucidate the relationship between lung function and bone mineral density (BMD) in a representative sample of children and adolescents. The analysis covered 3410 participants aged 8 to 19 years. We employed weighted multivariate linear regression and restricted cubic spline curve visualizations to explore the intricate association between lung function metrics, particularly first-second expiratory volume 1 second/forced vital capacity ratio, and lumbar BMD. Our data indicated a positive association between lung function and lumbar BMD in children and adolescents. Specifically, higher lung function metrics were linked with increased lumbar BMD. This association was more pronounced in younger participants or those with a lower body mass index. A significant positive relationship exists between lung function and BMD in the pediatric population. Recognizing this association is crucial for holistic health strategies for children and adolescents. This study underscores the need for integrated health monitoring during formative years, which can influence health trajectories as these individuals transition to adulthood.

Abstract
Chronic obstructive pulmonary disease (COPD) is a serious respiratory disease with high morbidity, disability and mortality worldwide. Every year, many people die from the disease or its comorbidities. Osteoporosis is a common complication of COPD, which can lead to increased fractures in COPD patients, aggravate the disease, and then bring great pain and burden to patients. The possible factors leading to osteoporosis in COPD patients include systemic inflammation, corticosteroid use, vitamin D deficiency, physical inactivity, tobacco exposure, lower bone mineral density, hypogonadism, hypoxia, and anemia. In clinical practice, the rate of diagnosis and treatment of osteoporosis in patients with COPD is low. Several studies demonstrated that treating osteoporosis with bisphosphonates could improve bone density, make breathing easier, and improve the quality of life of COPD patients. However, no studies have examined the effect of anti-osteoporosis therapy on fracture prevention in COPD patients. More research is needed to clarify how to implement holistic medical interventions in COPD patients with osteoporosis. We recommend that every COPD patient be screened for osteoporosis and treated with standard medications for primary osteoporosis.

Abstract
UNLABELLED The relationship between pulmonary function (PF) and bone mineral density (BMD) remains controversial. In the US population, we found a positive association between PF and BMD. Mixed variables such as age, gender, and race may influence this association. INTRODUCTION Based on the data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2010, this study explored whether there is a correlation between PF (1st second forceful expiratory volume as a percentage of expected value (FEV1(% predicted)), (one-second rate (FEV1/FVC)), and bone mineral density. METHODS We evaluated the relationship between PF and BMD in 6327 NHANES subjects (mean age 44.51 ± 15.64 years) from 2007 to 2010. The bone mineral density of the whole femur was measured by dual-energy X-ray absorptiometry (DXA). After adjusting for a wide range of confounders, we examined the relationship between PF and total femur BMD using a multiple linear regression model. RESULTS Correction of race, age, alcohol consumption, body mass index (BMI), height, poor income ratio (PIR), total protein, serum calcium, serum uric acid, cholesterol, serum phosphorus, blood urea nitrogen, FEV1(% predicted), and femur BMD were positively correlated (β = 0.032, 95% CI: 0.010-0.054, P = 0.004). FEV1/FVC was positively correlated with spine BMD (β = 0.275 95%CI: 0.102-0.448, P = 0.002). CONCLUSIONS Our study shows that PF is positively associated with BMD in the US population. A variety of factors such as race and age influence this relationship. the relationship between PF and BMD needs to be further investigated, including specific regulatory mechanisms and confounding factors.

Abstract
BACKGROUND The Northern Ireland Cohort for the Longitudinal Study of Ageing (NICOLA) is a prospective, longitudinal study of a representative cohort of older adults living in Northern Ireland, United Kingdom. Its aim is to explore the social, behavioural, economic and biological factors of ageing and how these factors change as people age. The study has been designed to maximize comparability with other international studies of ageing thereby facilitating cross-country comparisons. This paper provides an overview of the design and methodology of the health assessment which was carried out as part of Wave 1. METHODS Three thousand, six hundred and fifty five community dwelling adults, aged 50 years and over participated in the health assessment as part of Wave 1 of NICOLA. The health assessment included a battery of measurements across various domains that addressed key indicators of ageing namely: physical function, vision and hearing, cognitive function, and cardiovascular health. This manuscript describes the scientific rationale for the choice of assessments, provides an overview of the core objective measures carried out in the health assessment and describes the differences in characteristics of participants who took part in the health assessment compared to those who did not take part. RESULTS The manuscript highlights the importance of incorporating objective measures of health in population based studies as a means of complementing subjective measures and as a way to advance our understanding of the ageing process. The findings contextualize NICOLA as a data resource within Dementias Platform UK (DPUK), the Gateway to Global Ageing (G2G) and other existing networks of population based longitudinal studies of ageing. CONCLUSION This manuscript can help inform design considerations for other population based studies of ageing and facilitate cross-country comparative analysis of key life-course factors affecting healthy ageing such as educational attainment, diet, the accumulation of chronic conditions (including Alzheimer's disease, dementia and cardiovascular disease) as well as welfare and retirement policies.

Associations between lung function and physical and cognitive health in the Canadian Longitudinal Study on Aging (CLSA): A cross-sectional study from a multicenter national cohort. PLoS Med 2022; 19:e1003909. [PMID: 35139083 PMCID: PMC8870596 DOI: 10.1371/journal.pmed.1003909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 02/24/2022] [Accepted: 01/10/2022] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Low lung function is associated with high mortality and adverse cardiopulmonary outcomes. Less is known of its association with broader health indices such as self-reported respiratory symptoms, perceived general health, and cognitive and physical performance. The present study seeks to address the association between forced expiratory volume in 1 second (FEV1), an indicator of lung function, with broad markers of general health, relevant to aging trajectory in the general population. METHODS AND FINDINGS From the Canadian general population, 22,822 adults (58% females, mean age 58.8 years [standard deviation (SD) 9.6]) were enrolled from the community between June 2012 and April 2015 from 11 Canadian cities and 7 provinces. Mixed effects regression was used to assess the cross-sectional relationship between FEV1 with self-reported respiratory symptoms, perceived poor general health, and cognitive and physical performance. All associations were adjusted for age, sex, body mass index (BMI), education, smoking status, and self-reported comorbidities and expressed as adjusted odds ratios (aORs). Based on the Global Lung Function Initiative (GLI) reference values, 38% (n = 8,626) had normal FEV1 (z-scores >0), 37% (n = 8,514) mild (z-score 0 to > -1 SD), 19% (n = 4,353) moderate (z-score -1 to > -2 SD), and 6% (n = 1,329) severely low FEV1 (z-score = < -2 SD). There was a graded association between lower FEV1 with higher aOR [95% CI] of self-reported moderate to severe respiratory symptoms (mild FEV1 1.09 [0.99 to 1.20] p = 0.08, moderate 1.45 [1.28 to 1.63] p < 0.001, and severe 2.67 [2.21 to 3.23] p < 0.001]), perceived poor health (mild 1.07 [0.9 to 1.27] p = 0.45, moderate 1.48 [1.24 to 1.78] p = <0.001, and severe 1.82 [1.42 to 2.33] p < 0.001]), and impaired cognitive performance (mild 1.03 [0.95 to 1.12] p = 0.41, moderate 1.16 [1.04 to 1.28] p < 0.001, and severe 1.40 [1.19 to 1.64] p < 0.001]). Similar graded association was observed between lower FEV1 with lower physical performance on gait speed, Timed Up and Go (TUG) test, standing balance, and handgrip strength. These associations were consistent across different strata by age, sex, tobacco smoking, obstructive, and nonobstructive impairment on spirometry. A limitation of the current study is the observational nature of these findings and that causality cannot be inferred. CONCLUSIONS We observed graded associations between lower FEV1 with higher odds of disabling respiratory symptoms, perceived poor general health, and lower cognitive and physical performance. These findings support the broader implications of measured lung function on general health and aging trajectory.

Addiction-Associated Genetic Variants Implicate Brain Cell Type- and Region-Specific Cis-Regulatory Elements in Addiction Neurobiology. J Neurosci 2021; 41:9008-9030.

Abstract
Recent large genome-wide association studies have identified multiple confident risk loci linked to addiction-associated behavioral traits. Most genetic variants linked to addiction-associated traits lie in noncoding regions of the genome, likely disrupting cis-regulatory element (CRE) function. CREs tend to be highly cell type-specific and may contribute to the functional development of the neural circuits underlying addiction. Yet, a systematic approach for predicting the impact of risk variants on the CREs of specific cell populations is lacking. To dissect the cell types and brain regions underlying addiction-associated traits, we applied stratified linkage disequilibrium score regression to compare genome-wide association studies to genomic regions collected from human and mouse assays for open chromatin, which is associated with CRE activity. We found enrichment of addiction-associated variants in putative CREs marked by open chromatin in neuronal (NeuN+) nuclei collected from multiple prefrontal cortical areas and striatal regions known to play major roles in reward and addiction. To further dissect the cell type-specific basis of addiction-associated traits, we also identified enrichments in human orthologs of open chromatin regions of female and male mouse neuronal subtypes: cortical excitatory, D1, D2, and PV. Last, we developed machine learning models to predict mouse cell type-specific open chromatin, enabling us to further categorize human NeuN+ open chromatin regions into cortical excitatory or striatal D1 and D2 neurons and predict the functional impact of addiction-associated genetic variants. Our results suggest that different neuronal subtypes within the reward system play distinct roles in the variety of traits that contribute to addiction.SIGNIFICANCE STATEMENT We combine statistical genetic and machine learning techniques to find that the predisposition to for nicotine, alcohol, and cannabis use behaviors can be partially explained by genetic variants in conserved regulatory elements within specific brain regions and neuronal subtypes of the reward system. Our computational framework can flexibly integrate open chromatin data across species to screen for putative causal variants in a cell type- and tissue-specific manner for numerous complex traits.

Abstract
Objectives Systemic consequence of Chronic Obstructive Pulmonary Disease (COPD) is associated with progressive loss of muscle mass and function. Preliminary studies showed presence of sarcopenia in COPD leads to reduced pulmonary function and quality of life; studies on whether this condition results in consequent loss of bone mineral density (BMD) is still inconsistent. This study aims to examine the association of sarcopenia in COPD with osteoporosis. Methods This is a post-hoc analysis of a study on forty-one (n = 41) participants with COPD seen in a tertiary public hospital in Manila, Philippines who underwent pulmonary function test and dual-energy x-ray absorptiometry. Sarcopenia was defined using a Philippine-based criteria of low fat free mass index (FFMI) and low muscle strength - hand grip strength, and osteoporosis using World Health Organization T-score diagnostic criteria. Results The prevalence of osteoporosis among COPD is 44%, and 63% in COPD with sarcopenia. There was no statistical difference seen in pulmonary function variables between COPD with and without osteoporosis. Significant positive correlations were observed between Forced Expiratory Volume in 1 s, FFMI, and appendicular lean muscle with total body BMD. Sarcopenia in COPD was associated with significantly increased risk for osteoporosis. Conclusions High prevalence rate of osteoporosis, and even higher among sarcopenic Filipino COPD patients should be further studied. The findings also suggest that sarcopenia in COPD is associated with increased risk of osteoporosis, and osteoporosis alone does not seem to affect lung function.

Abstract
Objective: The aim of this work was to examine the association between adherence to a Mediterranean diet (MD) and lung function in older adults.Design: This was an observational and cross-sectional study.Setting: This research was conducted among community-dwelling older adults from the 2014 Health and Retirement Study (HRS).Subjects: Subjects were 2108 adults aged 50 years or older, 1234 (58.5%) of whom were female.Measures: Dietary intakes from respondents of the Health and Retirement Study (HRS) were used for the current analysis. Adherence to MD was evaluated using the MedDietScore, while lung function was evaluated through peak expiratory flow rate (PEF; l/min). Multiple linear regression and logistic regression were performed, adjusted for potential confounders, to examine the relation between adherence to MD and lung function.Results: Mean MedDietScore was 28.0 (± 5.0), indicating a moderate adherence to MD. Multiple linear regression showed a significant association between the MedDietScore and lung function (β = 0.072, 95% confidence interval [CI]: 0.039-0.104) after adjusting for age, gender, body mass index, race, comorbidities, education, height, grip strength, smoking history, physical activity, and daily caloric intake. Specific food groups such as grains, dairy products, and fish consumption were also associated with PEF rate (p < 0.05). Logistic regression confirmed these findings, and high adherence to MD was associated with reduced risk of having PEF rate < 80% of its peak predictive value (odds ratio: 0.65, 95% CI: 0.48-0.89).Conclusions: The results of this study indicate that adherence to MD is an independent predictor of lung function in older adults, and dietary interventions could be a possible preventive measure in adults with a high risk of developing lung function decline.

Abstract
Background Bone mineral density (BMD) has been positively associated with lung function in patients diagnosed with respiratory diseases such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis. However, the relationship between BMD and lung function is inconsistent in the general population. Methods To investigate the association between BMD and lung function in a Chinese general population, a total of 1024 adults aged 40–70 years old from Qiliying (an industrial polluted exposure area) and Langgongmiao (the reference area with non-industrial pollution) were recruited and underwent BMD and spirometry tests. Results Both BMD and lung function levels were lower in the exposed area compared to the reference area. In addition, BMD and lung function levels were also lower in females compared to males. Both Spearman and partial correlation analyses showed that BMD was positively correlated with FVC and FEV1. After adjusting linear regression analyses for potential confounding factors, every 0.1 g/cm2 drop in BMD was associated with 53.0 mL decrease in FVC and 33.5 mL decrease in FEV1. Conclusions A reduction of BMD is associated with lower lung function in a general population from China.

Abstract
COPD is associated with a progressive loss of muscle mass and function. However, there is an unmet need to define and standardise methods to estimate the prevalence of sarcopenia in COPD patients. We performed a systematic review and meta-analysis of the prevalence of this extrapulmonary manifestation in COPD patients. We searched Embase, Medline (Ovid), CINAHL (EBSCO), Web of Science, Scopus and Google Scholar for studies published up to January 17, 2019, assessing sarcopenia in COPD patients based on low muscle mass and decreased muscle function. Interventional studies, in vitro experiments, protocols or reviews and meta-analyses were excluded. We estimated heterogeneity (I2) and assessed significance (Q) using a Chi-squared test for estimates obtained from random-effects models. 4465 articles were initially identified. After removing the duplicates and applying the selection criteria, we reviewed 62 full-text articles. Finally, 10 articles (n=2565 COPD patients) were included in this systematic review and meta-analyses. Overall, the prevalence of sarcopenia in patients with COPD was 21.6% (95% CI 14.6–30.9%, I2=94%), ranging from 8% in population-based to 21% in clinic-based studies, and 63% in COPD patients residing in nursing homes. Sarcopenia is frequently observed in COPD patients, with varying prevalence across population settings. Sarcopenia in COPD should be assessed using standardised tests and cut-off points from sarcopenia consensus criteria for clinical practice and international comparisons. We confirmed a high prevalence of sarcopenia in COPD patients, with varying prevalence across population settings. We recommend adhering to the sarcopenia consensus criteria to systematically evaluate the muscle health of COPD patients.http://bit.ly/2KA6weh
