RESUMEN

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation; however, pulmonary function does not fully account for patients' functional difficulties. The primary aim of the study was to determine the association between several domains of cognition and daily activity among those with COPD. METHOD: Eighty-nine former smokers completed a neuropsychological battery including measures across multiple domains of cognition, pulmonary function measures, and daily activity questionnaires. Using a cross-sectional design, we compared daily activity between former smokers with and without COPD using two measures (St. George's Respiratory Questionnaire [SGRQ] Activity Subscale and Lawton Instrumental Activities of Daily Living [IADL] Scale) and examined the association between cognition and daily activity among those with COPD. RESULTS: As expected, former smokers with COPD reported more difficulty than those without COPD on both activity measures (SGRQ Activity Subscale p < .001; Lawton IADL Scale p = .040). Among former smokers with COPD, poorer delayed recall was associated with more difficulty with daily activities (SGRQ Activity Subscale) (p = .038) while adjusting for severity of airflow limitation, exercise tolerance, oxygen use, dyspnea, and symptoms of anxiety and depression. CONCLUSION: The findings suggest that cognition is associated with daily activity in patients with COPD. Future research should examine whether cognitive interventions may help to maximize patients' engagement in daily activities.

RESUMEN

The human impulse to punish those who have unjustly harmed others (i.e., third-party punishment) is critical for stable, cooperative societies. Punishment selection is influenced by both harm outcome and the intent of the moral agent (i.e., the offender's knowledge of wrongdoing and desire that the prohibited consequence occur). We allocate severe punishments to those who commit violent crimes and milder punishments to those who commit non-violent crimes; and we allocate severe punishments to criminals who have malicious intent and milder punishments to criminals who lack malicious intent. Prior research has indicated that aversive, emotional responses of third-party judges may influence punishment allocation, as increased negative emotion correlates with more punitive punishments. Here, we show that patients with damage to the ventromedial prefrontal cortex (vmPFC; a region necessary for the normal generation of emotion), compared to other neurological patients and healthy adult participants, allocate more lenient third-party punishment to criminals who commit emotionally-evocative, violent crimes. By contrast, patients with vmPFC damage did not differ from comparison participants on punishment allocation for non-emotional, non-violent crimes. These results demonstrate the necessity of the vmPFC for the integration of emotion into third-party punishment decisions, and indicate that negative emotion influences third-party punishment allocation particularly for scenarios involving physical harm to another.

RESUMEN

Early stages of chronic obstructive pulmonary disease (COPD) are characterized by the loss and narrowing of terminal bronchioles in the lung, resulting in "air-trapping," often occurring before overt emphysema manifests. Individuals with an airway-predominant phenotype of COPD display extensive lung air-trapping and are at greater cardiovascular disease (CVD) risk than COPD patients with an emphysema-predominant phenotype. We hypothesized that the degree of computed tomography (CT)-quantified lung air-trapping would be associated with greater aortic and carotid artery stiffness and lower endothelial function, known biomarkers of CVD risk. Lung air-trapping was associated with greater aortic stiffness (carotid femoral pulse wave velocity, CFPWV) (r = 0.60, P = 0.007) and carotid ß-stiffness (r = 0.75, P = 0.0001) among adults with (n = 10) and without (n = 9) a clinical diagnosis of COPD and remained significant after adjusting for blood pressure (BP) and smoking history (pack-years) (carotid ß-stiffness: r = 0.68, P < 0.01; CFPWV r = 0.53, P = 0.03). The association between lung air-trapping and carotid ß-stiffness remained significant after additionally adjusting for age and forced expiratory volume 1(FEV1) (r = 0.64, P = 0.01). In the COPD group only (n = 10), lung air-trapping remained associated with carotid ß-stiffness (r = 0.82, P = 0.05) after adjustment for age, pack-years, and FEV1. In contrast, no association was observed between CFPWV and lung air-trapping after adjustment for BP, pack-years, age, and FEV1 (r = 0.12, P = 0.83). Lung air-trapping was not associated with endothelial function (brachial artery flow-mediated dilation) in the entire cohort (P = 0.80) or in patients with COPD only (P = 0.71). These data suggest that carotid artery stiffness may be a mechanism explaining the link between airway-predominant phenotypes of COPD and high CVD risk.NEW & NOTEWORTHY Previous cross-sectional studies have demonstrated greater large elastic artery stiffness and lower endothelium-dependent dilation in chronic obstructive pulmonary disease (COPD) patients compared with controls. Furthermore, COPD patients with emphysema have greater aortic stiffness than non-COPD controls, and the degree of stiffness is associated with emphysema severity. The present study is the first to demonstrate that even before overt emphysema manifests, lung air-trapping is associated with carotid artery stiffness in COPD patients independent of blood pressure, age, or smoking history.
