External validation of an IOS-derived model for airflow obstruction and COPD in a community-based cohort
Abstract A model based on impulse oscillometry (IOS) predicting airflow limitation and chronic obstructive pulmonary disease (COPD) has been developed in hospital-based populations. However, its diagnostic performance in community-recruited cohorts and its potential complementary value when combined with commonly used questionnaire-based tools remain to be evaluated.
Identifying patients with mild-to-moderate COPD who require intensified initial treatment to control annualized clinically important deterioration
Abstract The chronic obstructive pulmonary disease (COPD) guidelines recommend selecting initial treatment based on the severity of respiratory symptoms or exacerbation history. However, some patients still experience clinically important deterioration (CID) despite this strategy. Therefore, we aimed to identify the risk factors to guide initial treatment, focusing on mild-to-moderate COPD patients whose annualized CID cannot be controlled by a single-bronchodilator.

Global, regional, and national burden of chronic obstructive pulmonary disease and its attributable risk factors from 1990 to 2021: an analysis for the Global Burden of Disease Study 2021 | Respiratory Research | Full Text
In 2021, a total of 213.39 (95% UI 194.87 to 233.98) million prevalent cases of COPD were estimated, with an age-standardized prevalence of 2,512.86 (95% UI 2,293.93 to 2,748.52) per 100,000, a change of -1.46% (-3.36% to 0.39%) since 1990. A higher total number of female COPD patients and a higher age-standardized prevalence of male COPD patients were observed from 1990 to 2021 (Figure S1).
Effects of indigenous microorganisms on the CO2 adsorption capacity of coal
Carbon dioxide (CO2), a greenhouse gas primarily emitted from burning fossil fuels, is a key contributor to global climate change. CO2 geological sequestration technology has emerged as a stable, long-term solution to help mitigate this serious issue [1], [2], [3], [4]. Deep unmineable coal seams have become one of the preferred choices for CO2 storage owing to their considerable storage capacity and environmental compatibility.
Prevalence, risk factors, and mortality of COPD in young people in the USA: results from a population-based retrospective cohort
Weights and Taylor Linearization Procedures accounted for the complex survey design, survey non-response and planned oversampling of the elderly and races were adapted to make estimates that are representative of the US population (www.cdc.gov/nchs/nhanes/tutorials). Demographic characteristics of the young people who completed the spirometry were presented as mean (SD) for continuous measures and number (percentage) for categorical measures.

Global, regional, and national burden of asthma and its attributable risk factors from 1990 to 2019: a systematic analysis for the Global Burden of Disease Study 2019 | Respiratory Research | Full Text
In this study, the burden of asthma was analyzed based on the GBD database. We found that age-standardized asthma prevalence, mortality, and DALYs had marked declines in the past 30 years, but the number of prevalent and death cases of asthma increased. Many countries had higher DALYs rates in 2019 than expected based on their SDI. The Age-Period-Cohort effects of asthma prevalence and mortality were determined.
Formation of covalent metal-carbon contacts assisted by Ag+ for single molecule junctions
Formation of covalent metal–carbon contacts assisted by Ag+ for single molecule junctions† Kai Song,a Junfeng Lin,ab Xuwei Song,ab Bowen Yang,a Jia Zhu, *cd Yaping Zang *ab and Daoben Zhu a Abstract Covalent metal–carbon (M–C) contacts have long been pursued for constructing robust and high-performance molecular devices. Existing methods for creating such contacts usually rely on direct chemical reactions between metal electrodes and designed molecular ligands.

Cleavage of non-polar C(sp2)‒C(sp2) bonds in cycloparaphenylenes via electric field-catalyzed electrophilic aromatic substitution - Nature Communications
Abstract Electrophilic aromatic substitution (EAS) is one of the most fundamental reactions in organic chemistry. Using an oriented external electric field (OEEF) instead of traditional reagents to tune the EAS reactivity can offer an environmentally friendly method to synthesize aromatic compounds and hold the promise of broadening its scope.
