0001, FDR=0.05). Seventy-five percent of these patients had an emphysema diagnose. In the validation analysis, when analyzed longitudinally, hsa-miR-1246 was significantly downregulated in COPD patients with emphysema after 10 years (p= 0.019). However, no association was found between the expression of miR-1246 and any other lung function parameters (FEV
, PaO
, DL
, IC/TLC) within the follow-up period. GO and KEGG enrichment analysis revealed miR-1246 to be associated with target genes in several pathways involved in COPD/emphysema development.

Our findings suggest that hsa-miR-1246 may act as a biomarker of emphysema in COPD. Functional analysis is guaranteed to elucidate its role in COPD.

Long-acting muscarinic antagonist/long-acting β
-agonist (LAMA/LABA) provide greater improvements in lung function and symptoms than inhaled corticosteroid (ICS)/LABA in patients with chronic obstructive pulmonary disease (COPD). This study evaluated symptom burden and Global Initiative for Obstructive Lung Disease (GOLD) categorization among patients who recently initiated umeclidinium/vilanterol (UMEC/VI; LAMA/LABA) or fluticasone propionate/salmeterol (FP/SAL; ICS/LABA) single-inhaler dual therapy.

COPD-diagnosed Medicare Advantage enrollees aged ≥65 years were identified from the Optum Research Database (ORD). Eligible patients had ≥1 pharmacy claim for UMEC/VI or FP/SAL in the 6-month period before sample identification, with no evidence of triple therapy (ICS/LAMA/LABA), asthma, or lung cancer. Symptom burden was assessed via cross-sectional surveys using the COPD Assessment Test (CAT) and modified Medical Research Council (mMRC) dyspnea scale. Patients were classified into GOLD categories using paL were classified as GOLD A or B, despite GOLD recommending non-ICS-containing therapy in these patients. These findings support the need for routine assessment of symptoms in patients with COPD.
After controlling for baseline characteristics, symptom burden was similar between patients receiving UMEC/VI or FP/SAL. GOLD classification using mMRC produced more conservative results compared with CAT, potentially underestimating patient symptoms. Metabolism inhibitor Many patients receiving FP/SAL were classified as GOLD A or B, despite GOLD recommending non-ICS-containing therapy in these patients. These findings support the need for routine assessment of symptoms in patients with COPD.
Comorbid congestive heart failure (CHF) was associated with worse prognosis in patients with chronic obstructive pulmonary disease (COPD), while few studies specially investigated critically ill patients. This study investigated the associations between comorbid COPD with or without CHF and prognosis of patients admitted to intensive care units (ICU).

We conducted a retrospective cohort study in the Medical Information Mart for Intensive Care III database. Adult ICU patients were included and categorized as patients without COPD and CHF, patients with COPD but without CHF, patients with CHF but without COPD, and patients with both COPD and CHF. The study outcomes were 28-day mortality and 90-day mortality after ICU admission. Kaplan-Meier curves were plotted to estimate the survival distributions between groups and multivariable Cox regression analyses were employed to evaluate the associations between comorbid COPD and/or CHF and the study outcomes.

A total of 29,589 patients were included with 20,507 r mortalities, while these two risk factors seemed to play an independent role.Pharmacological medications used for the treatment of COPD patients have increased significantly. Long-acting bronchodilators have been recognized as the mainstay of the treatment of stable COPD, while ICS are usually added in patients with COPD who experience exacerbations, despite bronchodilator treatment. In the latest years, several studies have been published showing the beneficial effect of adding ICS on dual bronchodilation in patients suffering from more severe disease comparing triple therapy with several therapeutic regiments including dual bronchodilation and providing a message that this triple therapy might be more appropriate for COPD patients. However, not all COPD patients have a desirable response to ICS treatment while long-term ICS use in COPD is associated with several side effects. In this report, we aimed to provide a review of the current knowledge on the importance of dual bronchodilation on COPD patients and to compare its use with triple therapy, by covering a wide spectrum of topics. Finally, we propose an algorithm on performing treatment step up from dual bronchodilation to triple therapy and step down from triple to double bronchodilation considering the current evidence.
The concept of clinical control has been proposed as an instrument for evaluating patients with COPD. However, the possible association between clinical control, reduced symptom severity and HRQoL has yet to be confirmed.

This multicentre, prospective and observational study was carried out in 15 pulmonology clinics in Spain. The patients were followed up for six months, with a baseline visit (V0), followed by visits at three months (V1) and six months (V2). Clinical control was determined at V1, with the application of both clinical criteria and the COPD assessment test (CAT). All patients reported their symptoms by a validated symptom diary (E-RS) using a portable device, and their HRQoL was assessed using the EQ5D questionnaire. The relationship between clinical control and E-RS and HRQoL during follow-up was assessed with
-test.

A total of 126 patients were screened. After application of the inclusion/exclusion criteria, 93 were finally included (mean age 66 ± 8 years, 84.9% male), with a mean FEV
predicted of 49.8% ± 16.5%. Of these patients, 44 (47.3%) achieved clinical control at V1, according to CAT criteria, and 50 (53.8%), according to clinical criteria. The E-RS scores differed between controlled and uncontrolled patients at all time points, both according to CAT (mean differences of -4.6, -5.6 and -6.2 units at V0, V1 and V2, respectively, p<0.005 for all comparisons) and to clinical criteria (mean differences of -3.3, -5-6 and -4.99 units, respectively, p<0.005 for all comparisons). The controlled patients also presented a significantly better HRQoL, measured by the EQ5D questionnaire (mean difference 0.13 and 0.10 at V2 by CAT or clinical criteria, respectively, p<0.05).

Clinical control in patients with COPD, whether measured by CAT or by clinical criteria, is associated with a lower symptom load and a better HRQoL.
