objective: hyperglycemia is associated with increased morbidity and mortality in diabetic patients following coronary artery bypass grafting. tight glycemic control in perioperative period can reduce these events. the goal of this study was to determine whether combination of continuous infusion and subcutaneous glargine as a basal insulin could improve glycemic control. material and methods: d...

background & aims of the study: heavy metals discharge to environment is a worldwide problem growing in scale. when they accumulate in the environment and in food chains, they can profoundly disrupt biological processes. peganum harmala seeds (phs) was used as a bio-sorbent, using a continuous system for removing pb2+, co2+, ni2+ and cu2+ ions from aqueous solutions. materials and methods: phs ...

there is no randomized study carried out in order to compare their pharmacokinetic parameters although midazolam, as a sedative, has been widely administered via continuous infusion as well as intermittent bolus doses in mechanically ventilated critically ill patients. we prospectively investigated the effect of these two principal methods on pharmacokinetic parameters in 23 of mentioned patien...

peritoneal dialysis is an established form of renal replacement therapy used in many patients with end-stage renal disease. the key to a successful chronic peritoneal dialysis is a permanent and safe access to the peritoneal cavity. this study was conducted in order to evaluate the catheter survival and its related factors in imam khomeini hospital. a total of 80 catheters were inserted into 69...

background : patients undergoing pacemaker implantation often experience anxiety and fear. as such, studies have focused on the mechanisms that relieve the negative emotions caused by the intervention. continuous nursing is a safe and effective nursing mode. in this study, continuous nursing intervention was provided for elderly patients undergo-ing pacemaker implantation and an empirical inves...

conclusion a comparison of these data with those of other countries showed that there was considerable geographic variation in bacterial patterns of sensitivity and resistance properties. therefore, the selection of antibiotics for empiric therapy especially in children with terminal renal failure on continuous ambulatory peritoneal dialysis (capd) treatment should be based on the knowledge of ...

background and purpose: studies have shown the advantages of e-cme programs. developing case-based e-cme activities, one of the popular formats of e-cme programs, is difficult and time consuming. in this article we describe our experience of performing instructional system design for creating case-based e-cme contents.  methods: we performed a five-step instructional system design (i.e. system ...

background: phenobarbital poisoning is common in vietnam. the aim of this study was to compare the effectiveness of continuous veno-venous hemofiltration (cvvh) and hemodialysis (hd) on clinical outcomes in the treatment of severe acute phenobarbital poisoning. methods: this was a retrospective observational historically controlled study. 42 patients with severe phenobarbital poisoning were enr...

in the present work, a meshless method called finite point method (fpm) is developed to simulate the solidification process of a continuously cast steel bloom in both primary and secondary cooling regions. the method is based on the use of a weighted least-square interpolation procedure. a transverse slice of the bloom moving at casting speed is considered as the computational domain and two di...

due to the changes which may occur in their parameters, systems are usually demonstrated by some subsystems for different conditions. this paper employs modified petri nets (mpn) to model theses subsystems and makes it simple to analyze them. in this method, first, the continuous transfer function is converted to a discrete transfer function and then, by mpn, system is modeled and analyzed. all...
