BACKGROUND Coronary artery calcification is pathognomonic of coronary artery disease (CAD). Whether CAD in patients with COPD is linked to lung function, functional capacity and/or clinically relevant outcomes is unknown. The objective was to assess the association between CAD and disease severity, functional capacity and outcomes in patients with COPD. METHODS Coronary artery calcium score (...
CONTEXT The coronary artery calcium score (CACS) has been shown to predict future coronary heart disease (CHD) events. However, the extent to which adding CACS to traditional CHD risk factors improves classification of risk is unclear. OBJECTIVE To determine whether adding CACS to a prediction model based on traditional risk factors improves classification of risk. DESIGN, SETTING, AND PART...
We aimed to determine if chronic endurance-exercise habits affected redox status and paracrine function of CD34(+) and CD34(-)/CD31(+) circulating angiogenic cells (CACs). Subjects were healthy, nonsmoking men and women aged 18-35 yr and categorized by chronic physical activity habits. Blood was drawn from each subject for isolation and culture of CD34(+) and CD34(-)/CD31(+) CACs. No difference...
A conflict-avoiding code (CAC) C of length n with weight k is a family of binary sequences of length n and weight k satisfying ∑ 0≤t≤n−1 xitxj,t+s ≤ 1 for any distinct codewords xi = (xi0, xi1, . . . , xi,n−1) and xj = (xj0, xj1, . . . , xj,n−1) in C and for any integer s, where the subscripts are taken modulo n. A CAC with maximal code size for given n and k is said to be optimal. A CAC has be...
In a model with both issues of sovereign debtor moral hazard and creditor coordination under incomplete information, we show that the resulting conict between ex ante and interim e¢ ciency limits the welfare impact of strengthening CACs. Conditional on default, we show that an interim e¢ cient CAC threshold exists and improving creditor coordination results in welfare gains. However, when ex a...
Abstract Introduction Coronary artery calcium score (CACS) and exercise capacity (EC) are both independent prognostic tests in coronary disease (CAD). Purpose We aimed to assess the incremental role of EC CACS, particularly those with absent or low calcification. Methods The cohort consisted patients who had clinically indicated stress testing CACS assessment a median 27 days each other. was de...
OBJECTIVES The goal of this study was to compare the diagnostic accuracy of the coronary artery calcium score (CACS), coronary computed tomography angiography (CTA), single-photon emission computed tomography (SPECT), and a combination of these tools in the diagnosis of obstructive coronary artery disease (CAD) in patients with chronic kidney disease referred for cardiac evaluation before kidne...
BACKGROUND The prevalence of coronary artery stenosis (CAS) at the initiation of renal replacement therapy (RRT) in chronic kidney disease (CKD) patients has not been fully elucidated. Although coronary angiography is the gold standard in diagnosing CAS its invasiveness and economic burden lead to searching for a noninvasive alternative method. In this study, we evaluated the prevalence of CAS ...
BACKGROUND The management of cancer-related anorexia/cachexia syndrome (CACS) is a great challenge in clinical practice. To date, practice guidelines for the prevention and treatment of CACS are lacking. The authors conducted a randomized study to confirm the effectiveness and safety of treatment of CACS utilizing megestrol acetate (MA) plus thalidomide. METHODS One hundred and two candidates...
