Chronic obstructive pulmonary disease (COPD) is a highly prevalent inflammatory lung condition characterized by chronic respiratory symptoms and airflow obstruction that often lead to diminished quality of life. Non-pharmacologic management for patients with COPD involves smoking cessation and healthy lifestyle changes. Pharmacologic treatments include inhaled bronchodilators with or without the use of inhaled corticosteroids, which can be administered through inhalation or nebulization.

Despite increased insights into mechanisms underlying various asthma phenotypes and endotypes and the availability of targeted biologic treatment options, the disease remains uncontrolled in a substantial proportion of patients with risk of exacerbations, requiring systemic corticosteroids, and with progressive disease. Current international guidelines advocate a personalized management approach to patients with uncontrolled severe asthma.

We utilized the Mini International Neuropsychiatric Interview (MINI) to identify depression/anxiety disorders meeting DSM-V diagnostic criteria and described associated disease burden in people with COPD.
Methods: This is a cross-sectional, secondary analysis of a multi-center study designed to evaluate anxiety questionnaires in COPD patients.
Topic Importance: Chronic obstructive pulmonary disease (COPD) is a complex, heterogeneous lung disease characterized by persistent airflow limitation secondary to airways and parenchymal abnormalities, and respiratory symptoms, including dyspnoea, fatigue, chronic cough, and sputum production. Cigarette smoke exposure is a major contributor to COPD although inhalation of toxic particles and other environmental and host factors can contribute to its genesis. Over time, the clinical course is frequently punctuated by exacerbations that further accelerate lung function decline and increase exacerbation risk.

We sought to define the relationship of longitudinal IR with radiographic imaging outcomes and examiner-identified incident lung disease in the Framingham Offspring Study.
Research Design And Methods: Participants without baseline lung disease underwent repeated measurements of fasting insulin and glucose levels over an average period of 13.
Chronic obstructive pulmonary disease (COPD) is a progressive respiratory illness characterized by long-standing respiratory symptoms and airflow limitation. It is a major contributor to respiratory disease-related deaths and currently ranked as the sixth leading cause of mortality in the United States. Approved pharmacological therapies for the stable disease primarily consist of inhaled short and long-acting bronchodilators, inhaled corticosteroids, azithromycin, and roflumilast.

Objective: To assess clinical outcomes in patients from BOREAS by emphysema status.
Methods: Patients with COPD and type 2 inflammation (screening blood eosinophils ≥300 cells/μL) on maximal inhaled therapy were randomized to add-on dupilumab 300 mg or placebo every 2 weeks for 52 weeks.
Asthma and cardiovascular disease (CVD) often co-exist. When a patient has both conditions, management requires an approach that addresses the unique challenges of each condition separately, while also considering their potential interactions. However, specific guidance on the management of asthma in patients with CVD and on the management of CVD in patients with asthma is still lacking.

Background: Limited data exist on the relative impact of moderate and severe exacerbations on asthma control and impairment.
Objective: To explore data from the CAPTAIN trial to evaluate the relationship between first moderate or severe exacerbation and changes in lung function, symptoms, physical activity limitation scores, and short-acting β-agonist (SABA) usage to determine the clinical relevance of moderate events.
Methods: CAPTAIN was a phase IIIA 24- to 52-week, multicenter, international, randomized controlled trial evaluating efficacy and safety of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus FF/VI in patients with uncontrolled asthma on inhaled corticosteroid/long-acting β-agonist.
Background: Dupilumab, a fully human monoclonal antibody that blocks the shared receptor component for interleukin-4 and interleukin-13, key and central drivers of type 2 inflammation, has shown efficacy and safety in a phase 3 trial involving patients with chronic obstructive pulmonary disease (COPD) and type 2 inflammation and an elevated risk of exacerbation. Whether the findings would be confirmed in a second phase 3 trial was unclear.
Methods: In a phase 3, double-blind, randomized trial, we assigned patients with COPD who had a blood eosinophil count of 300 cells per microliter or higher to receive subcutaneous dupilumab (300 mg) or placebo every 2 weeks.
While polyborylated alkenes are being recognized for their elevated status as highly valuable reagents in modern organic synthesis, allowing efficient access to a diverse array of transformations, including the formation of C-C and C-heteroatom bonds, their potential as energy-transfer reactive groups has remained unexplored. Yet, this potential holds the key to generating elusive polyborylated biradical species, which can be captured by olefins, thereby leading to the construction of new highly-borylated scaffolds. Herein, we report a designed energy-transfer strategy for photosensitized [2+2]-cycloadditions of poly-borylated alkenes with various olefins enabling the regioselective synthesis of diverse poly-borylated cyclobutane motifs, including the 1,1-di-, 1,1,2-tri-, and 1,1,2,2-tetra-borylated cyclobutanes.

Purpose: This study aimed to examine reports of cardiovascular adverse events (CV AEs) observed in the real-world during treatment with aclidinium, tiotropium, glycopyrronium, and umeclidinium alone or in combination with a LABA and, in the context of triple therapy, with the addition of an ICS, and submitted to the food and drug administration adverse event reporting system (FAERS).
Methods: A retrospective disproportionality analysis was conducted utilizing CV AE reports submitted to the FAERS from January 2020 to 30 September 2023. Disproportionality was measured by calculating the reporting odds ratio.
For patients with moderate-to-severe persistent allergic asthma, omalizumab is approved for subcutaneous administration according to a recommended dosing table based on weight and total immunoglobulin E (IgE) level. The aim of this analysis was to assess asthma outcomes including quality of life in patients with allergic asthma initiated on omalizumab in the PROSPERO trial; patients were stratified by where their IgE and body weight fell on the approved dosing table. Patient groups were defined as Inside Dosing Table: patients whose IgE and weight fell within the approved dosing table (n = 506); Insufficient Data to Recommend a Dose: patients who fell into the section of the approved dosing table where not enough clinical data were available to make dosing recommendations (n = 72); and Outside Dosing Table: patients who fell outside the approved dosing table due to baseline IgE and/or weight (n = 209).
View Article and Find Full Text PDFAsthma is a heterogeneous disease commonly driven by allergic and/or eosinophilic inflammation, both of which may be present in severe disease. Most approved biologics for severe asthma are indicated for specific phenotypes and target individual downstream type 2 components of the inflammatory cascade. Tezepelumab, a human monoclonal antibody (immunoglobulin G2λ), binds specifically to thymic stromal lymphopoietin (TSLP), an epithelial cytokine that initiates and sustains allergic and eosinophilic inflammation in asthma.

In this retrospective study, we quantified the impact of antiviral therapy on exacerbations, healthcare resource utilization (HRU), and costs in patients with COPD across 5 influenza seasons.
Methods: Using claims data from US MarketScan® databases, we identified patients with COPD who had an influenza diagnosis during the 2012-2016 influenza seasons.
Based on current clinical guidelines, long-acting β2-agonists (LABA) are frequently prescribed before long-acting muscarinic antagonists (LAMA) as an add-on to inhaled corticosteroids (ICS) in uncontrolled asthma. However, there is insufficient real-world evidence that supports this therapeutic approach. The objective was to compare asthma exacerbations and healthcare resource utilization in patients with asthma using the LAMA tiotropium bromide (Tio) or a LABA as an add-on to ICS (ICS + Tio or ICS/LABA) in a real-world setting.
