Problem The purpose of this study is to discover unique themes related to the attitudes of nurses in Southern Mississippi toward physician-assisted death (PAD). Methods This study is a qualitative, inductive content analysis. The sample comprised three registered nurses currently practicing in Southern Mississippi. The researcher guided each participant’s one-hour interview with questions, then...
A new structure design of bond pad is proposed to reduce its parasitic capacitance in general CMOS processes without extra process modification. The proposed bond pad is constructed by connecting multilayer metals and inserting additional diffusion layers into the substrate below the metal layers. The metal layers except top metal layer are designed with special patterns, which have smaller are...
BACKGROUND The clinical utility of ankle-brachial index (ABI) is not clear in subjects with less severe or calcified vessel. Therefore, we investigated the usefulness of color Doppler ultrasonography for diagnosing peripheral artery disease (PAD) in type 2 diabetes mellitus (T2DM) subjects. METHODS We analyzed 324 T2DM patients who concurrently underwent ABI and carotid intima-media thickness...
Peripheral arterial disease (PAD) causes morbidity and is associated with mortality. B vitamin intake has been inversely associated with coronary heart disease, but their effects on PAD are not known. We examined prospectively the relationships between dietary folate, vitamin B-6 and B-12 and PAD risk in 51529 male U.S. health professionals, aged 40 to 75 y, who answered a detailed 131-item que...
BACKGROUND/AIMS Periampullary diverticulum (PAD) causes difficulty in the extraction of common bile duct (CBD) stones with conventional endoscopic therapy. Our study was designed to evaluate the effect of PAD on endoscopic large balloon dilation (EPLBD) with/without limited endoscopic sphincterotomy (EST) for CBD stone treatment. METHODS We retrospectively reviewed cases of 141 patients treat...
The atherothrombotic conditions, coronary artery disease, cerebrovascular disease and peripheral arterial disease (PAD), together account for almost one-half of all deaths in Europe each year; however, perception of the specific risks associated with PAD is generally poor compared with its related conditions. PAD is not just a localised disease--it has serious systemic effects, and affected ind...
In this paper, a general rough-pad model is proposed for the chemical mechanical polishing CMP process. The proposed rough-pad model has several advantages over existing models. First, general height distribution functions and autocorrelation functions are used to describe the pad surface, which are easier to obtain than pad asperity height and curvature distributions in existing models. Second...
Background. Peripheral arterial disease (PAD) often coexists with congestive heart failure (CHF) and can be masked by symptoms of CHF such as functional limitation (FL), a common manifestation for both. Therefore, we sought to estimate the prevalence of PAD and its independent association with FL in CHF. Methods. We conducted a cross-sectional study on National Health and Nutrition Examination ...
Peripheral arterial disease (PAD) is widely used to describe a common disease process in which blood flow to the lower extremities is impaired as a result of atherosclerotic occlusive disease. PAD, an under-diagnosed and under-treated disorder with substantial morbidity and mortality, affects up to 10 million people in the United States. The pathophysiology of peripheral arterial disease and th...
Pad cratering in the PCB is a new failure mode encountered in electronic assemblies, particularly in lead-free products. The failure mechanisms and root causes are not yet fully understood, and lack appropriate industry standard tests for PCB qualification with regard to pad cratering. This paper reviews major publications and research reports on various PCB materials from industry studies in t...
