For those living at high altitude, any gas exchange abnormality is compounded by reduced partial pressures of inspired oxygen. <b>Objectives:</b> Does residence at higher altitude exposure affect COPD outcomes, including lung function, imaging characteristics, symptoms, health status, functional exercise capacity, exacerbations, and mortality? <b>Methods:</b> From the SPIROMICS (Subpopulation and Intermediate Outcome Measures in COPD Study) cohort, we identified individuals with COPD living below 1,000 ft (305 m) elevation (<i>n</i> = 1,367) versus above 4,000 ft (1,219 m) elevation (<i>n</i> = 288). Multivariable regression models were used to evaluate associations of exposure to high altitude with COPD-related outcomes. <b>Measurements and Main Results:</b> Living at higher altitude was associated with reduced functional exercise capacity as defined by 6-minute-walk distance (-32.3 m [95% confidence interval, -49.8 to -14.8 m]). There were no differences in patient-reported outcomes as defined by symptoms (COPD Assessment Test and modified Medical Research Council dyspnea scale), or health status (St. George's Respiratory Questionnaire). Higher altitude was not associated with a different rate of FEV₁ decline. Higher altitude was associated with lower odds of severe exacerbations (incidence rate ratio, 0.65 [95% confidence interval, 0.46 to 0.90]). There were no differences in small airway disease, air trapping, or emphysema. In longitudinal analyses, higher altitude was associated with increased mortality (hazard ratio, 1.25 [95% confidence interval, 1.0 to 1.55]); however, this association was no longer significant when accounting for air pollution. <b>Conclusions:</b> Long-term altitude exposure is associated with reduced functional exercise capacity in individuals with COPD, but this did not translate into differences in symptoms or health status. In addition, long-term high-altitude exposure did not affect progression of disease as defined by longitudinal changes in spirometry.

In addition, 16S rRNA gene sequencing data and viral and bacterial load of BAL samples from a subset of these patients, and of patients requiring noninvasive ventilation, were analyzed. We integrated 16S rRNA gene sequencing data with existing immune parameter datasets. <b>Measurements and Main Results:</b> Potential bacterial pathogens were detected in 20% (28/142) of patients with influenza and 37% (104/281) of patients with COVID-19, whereas aspergillosis was detected in 38% (54/142) of patients with influenza and 31% (86/281) of patients with COVID-19. A significant association between bacterial pathogens in BAL fluid and 90-day mortality was found only in patients with influenza, particularly patients with IAPA. Patients with COVID-19, but not patients with influenza, showed increased proinflammatory pulmonary cytokine responses to bacterial pathogens. <b>Conclusions:</b> Aspergillosis is more frequently detected in the lungs of patients with severe influenza than bacterial pathogens.

Traditional strategies involve directly conjugating heavy atoms to the chromophore, which often broadens the emission spectrum. This study explores an unconventional approach using the through-space heavy-atom effect, positioning heavy-atom moieties with nonconjugated short-range interaction with the chromophore. This method successfully demonstrates the “intramolecular external heavy-atom effect” proposed in the 1970s in cutting-edge high-efficiency emissive materials. Comparative analysis of these emitters confirms the spatial heavy-atom effect, maintaining the spectroscopic properties of MR chromophore while significantly improving external quantum efficiency in organic light-emitting diodes (OLEDs). These emitters also mitigate efficiency roll-off, showcasing the potential of spatial interactions to enhance MR-TADF materials for OLED applications.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"13 1","pages":""},"PeriodicalIF":23.5,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142610117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve this critical problem, here we propose a pseudohalide anion alloying process to regulate the crystallization of inorganic CsSnI₃ perovskite and achieve large grain sizes in the micron range. The introduction of a pseudohalide anion changes the phase transition pathways through the formation of intermediates, thereby slowing the rate of CsSnI₃ crystallization. The substitutional alloying of HCOO^– in the CsSnI₃ crystal lattice further improves the oxidation resistance of Sn²⁺ due to the strong bonding between the HCOO^– anions and Sn²⁺ cations. The fabricated CsSnI₃-based planar perovskite solar cell with an inverted configuration and active area of 4.05 mm² exhibits certified power conversion efficiency of 13.68% at AM 1.5 solar irradiation (100 mW cm^–2), which is among the best reported for CsSnI₃-based inorganic perovskite cells.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"24 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142610442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
