BACKGROUND Generalized anxiety disorder (GAD) is common among people with asthma, but its association with asthma morbidity remains unexplored. This study examined cross-sectional associations between GAD and asthma control, quality of life, and self-efficacy. METHODS Seven hundred ninety-four adults with confirmed asthma were recruited from the(More)
INTRODUCTION Despite the availability of effective therapies, research indicates that more than 50% of asthmatics are poorly controlled. Poor asthma control has been linked to behavioral (i.e., cigarette smoking) and psychological factors (i.e., anxiety and depression). However, little is known about the individual versus combined impact of cigarette(More)
OBJECTIVES To evaluate the impact of covariates on performance accuracy of the Beck Depression Inventory II (BDI-II) and to determine the optimal cut-off score for the BDI-II in cardiac outpatients. Differences of optimal cut-off scores were also verified across covariate subgroups. DESIGN AND SETTING Prospective cross-sectional study at the Department of(More)
BACKGROUND Psychological stress has long been suspected to have a deleterious effect on asthma, with acute psychological stress being associated with physiological responses in asthma patients. OBJECTIVES The purpose of this systematic review was to provide a narrative synthesis of the impact of acute laboratory psychological stress on physiological(More)
Impaired endothelial function has been shown to limit exercise in coronary artery disease (CAD) patients and has been implicated in myocardial ischemia. However, the association of endothelial function and ischemia on peak exercise oxygen consumption (VO(2)) has not been previously reported. A total of 116 CAD patients underwent standard exercise stress(More)
OBJECTIVE The Beck Depression Inventory II (BDI-II) is one of the most frequently used tools to screen for depression in patients with chronic diseases such as cardiovascular disease and asthma. However, its original cut-off score has not been validated in adult asthmatics. The present study aimed to determine the optimal BDI-II cut-off score and to verify(More)
Although there is evidence that depression is associated with an increased risk for coronary artery disease (CAD), the mechanisms underlying this association remain unclear. This study examined the association between depression and hemodynamic, hemostatic, and endothelial responses to psychological stress. Seventy-two postcoronary angiography patients(More)
