Direct stenting without antecedent dilatation may reduce procedural time, costs, and radiation exposure, and may result in less vessel injury. The purpose of this investigation was to compare immediate and long-term clinical and angiographic outcomes of direct stenting with stent placement after initial balloon dilation. Three hundred thirty-five symptomatic patients with single or multiple cor...

The Clinical and Angiographic analysis with a Cobalt Alloy Coronary Stent (Driver) (CLASS) study was a prospective, nonrandomized, multicenter study designed to assess the safety and efficacy of a cobalt-chromium alloy-based stent in patients with stable or unstable angina pectoris. A total of 203 lesions were treated in 202 enrolled patients. The percentage of major adverse cardiac event-free ...

OBJECTIVES Little is known about procedural sedation use for anxiety and pain associated with skin and soft tissue infections (SSTIs) requiring incision and drainage (I&D). Our objectives were therefore (1) to characterize the use of procedural sedation use for SSTI I&D procedures in pediatric emergency departments (EDs), (2) to compare the frequency of procedural sedation for I&D across hospit...

Procedural geometry paradigms are analyzed and classified as either “data amplifier” or “lazy evaluation.” Lazy evaluation reduces the size of the geometric representation passed to renderers and increases the flexibility of procedural experimentation. Several existing procedural geometry systems are compared in this light, and a new one is proposed, called procedural geometric instancing. Insp...

OBJECTIVE Data suggest parents' preprocedural anxiety is related to children's acute procedural anxiety and pain. This study examined the temporal relations among these constructs to determine whether children's anxiety mediates the relation between parents' anticipatory anxiety and children's procedural pain. METHODS A total of 90 preschoolers receiving immunizations, their parents, and the ...

This study sought to compare Iranian EFL novice and expert teachers regarding their procedural knowledge in Iranian language institutes and universities. A questionnaire was developed based on the literature, the theoretical framework, and the results of a qualitative study. This questionnaire was administered to the whole sample of the study who was 200 Iranian EFL teachers from different gend...

Style and strategies in EFL learning contexts and the effects of task types were explored to enhance language learning strategies. Using a quantitative pre-test, post-test design and interviews, this study investigated the effects of procedural and declarative learning strategies on EFL learners’ acquisition of English past tense performing narrative tasks. The participants were 396 male and fe...

BACKGROUND Interruptions have been implicated as a cause of clinical errors, yet, to our knowledge, no empirical studies of this relationship exist. We tested the hypothesis that interruptions during medication administration increase errors. METHODS We performed an observational study of nurses preparing and administering medications in 6 wards at 2 major teaching hospitals in Sydney, Austra...
