BACKGROUND AND PURPOSE Controversy exists regarding the utility of antecedent venography in percutaneous vertebroplasty. Our purpose was to determine whether antecedent venography improves clinical outcomes and/or decreases extravertebral cement extravasation in these procedures. METHODS We retrospective reviewed outcomes of consecutive percutaneous vertebroplasty procedures performed at our ...

background the purpose of this study was to measure the level of quality of work life (qwl) among hospital employees in iran. additionally, it aimed to identify the factors that are critical to employees’ qwl. it also aimed to test a theoretical model of the relationship between employees’ qwl and their intention to leave the organisation. methods a survey study was conducted based on a sample ...

BACKGROUND Antecedent hypertension is associated with poor outcome in patients with ST-elevation myocardial infarction (STEMI). Whether differences in myocardial salvage, infarct size and microvascular injury contribute to the adverse outcome is unknown. We investigated the association between antecedent hypertension and cardiovascular magnetic resonance (CMR) parameters of myocardial salvage a...

BACKGROUND Recent studies suggest that patients with angina before myocardial infarction exhibit improved recovery of coronary perfusion after thrombolysis by an as-yet-unknown mechanism. We therefore proposed that brief antecedent ischemia/reperfusion may, via release of adenosine, improve vessel patency in damaged and stenotic coronary arteries. METHODS AND RESULTS Anesthetized dogs underwe...

Recurrent hypoglycemia impairs hormonal counterregulatory responses (CRRs) to further bouts of hypoglycemia. The hypothalamus and hindbrain are both critical for sensing hypoglycemia and triggering CRRs. Hypothalamic glucose sensing sites are implicated in the pathogenesis of defective CRRs; however, the contribution of hindbrain glucose sensing has not been elucidated. Using a rat model, we co...

A marked sexual dimorphism exists in healthy individuals in the pattern of blunted neuroendocrine and metabolic responses following antecedent stress. It is unknown whether significant sex-related counterregulatory differences occur during prolonged moderate exercise after antecedent hypoglycemia in type 1 diabetes mellitus (T1DM). Fourteen patients with T1DM (7 women and 7 men) were studied du...

The resolution of anaphora is dependent on a number of factors discussed in the literature: syntactic parallelism, topicality, etc. A system that attempts to resolve anaphora will typically require the interaction of many of these factors. In addition, there must be a principle that simply says that the system needs to look for an antecedent. Without such a principle, if none of the factors rec...

OBJECTIVE Antecedent hypoglycemia can blunt neuroendocrine and autonomic nervous system responses to next-day exercise in type 1 diabetes. The aim of this study was to determine whether antecedent increase of plasma cortisol is a mechanism responsible for this finding. RESEARCH DESIGN AND METHODS For this study, 22 type 1 diabetic subjects (11 men and 11 women, age 27 +/- 2 years, BMI 24 +/- ...
