].Background Education programs teaching crisis resource management (CRM) skills (problem solving, situational awareness, resource utilization, communication, and leadership) have been shown to positively affect learner competence in handling crisis events. As part of an education program, a high-fidelity simulation program was used as a learning intervention to teach these skills to practicing nurses. Method In this repeated-measures observational study, 11 RNs were evaluated at four time points, measuring the effect of an education program on observed performance of CRM skills. Performance was measured using the Ottawa Global Rating Scale and a checklist tool. Results Statistically significant changes in mean scores occurred between times one and two, and nonstatistically significant improvement occurred in means overall. Conclusion This study adds evidence of the effectiveness of high-fidelity simulation education and highlights the need for further research.

While there are numerous studies on the effect of this neurotoxin, still further investigation is required to understand the influence of this toxin on different regions of the brain. In the present study, there are two groups of rats of which one is treated with 3-NP. Behavioral, stereological and immunohistochemical analyses were conducted. The results show that locomotor activity is largely affected and anxiety is induced up to a certain level, but there is no gross manifestation of deficit in memory. Microscopic observations illustrate damages in the hippocampus and other parts of the brain. Astrogliosis and glial scars were another finding of this study. In conclusion, although 3-NP can be used as a model of Huntington's disease, it exerts a disseminated effect on different regions of the brain.Objective Quantifying the absolute coronary blood flow can be done using continuous infusion thermodilu-tion requiring a dedicated infusion catheter. Up to now, there is little insight in the effect of small variabilities in the physical parameters on the temperature gradient along this catheter. Selleck HPPE The key goal of this study is to develop and validate a computer model that predicts the temperature of the infusion fluid at the infusion site of the infusion catheter. A secondary goal is to gain insight in the influence of physical variations for the indi-vidual patient on the calculated blood flow rate. Approach A numerical model of the temperature in the catheter was built using the convection-diffusion equation and validated using an in vitro setup. A sensitivity analysis was performed to investigate the influence of the catheter path inside the body and the temperature of the infusion fluid at different infusion rates. These results were compared to in vivo measurements of 94 patients. Finally, the variation in the computed blood flow rate is estimated considering an average patient, using small variations in the physical parameters. Main results The computed temperature corresponded well with the in vitro measurements, since a maximal difference of 1.5% was observed. The length of the catheter path inside the body had the most influence on the temperature of the infusion fluid at the infusion site. Moreover, temperatures from the numerical model were similar to the results from in vivo measurements. By varying the length of the catheters with 0.04m, the largest deviation in the calculated blood flow was 33.3mL/min. Significance Insight is gained in the influence of physical variations on the temperature of the infusion fluid at the infusion site of the catheter using thermodilution. The developed numerical model can possibly be used to reduce time in estimating the blood flow rate.In the phenomenon of simultaneous brightness contrast, two patches, one on a dark background and the other on a light one, appear to have different brightness despite being physically equi-luminant. Elucidating the phenomenon's underlying mechanisms is relevant for the larger question of how the visual system makes photometric judgments in images. Accounts over the past century have spanned low-, mid- and high-level visual processes, but a definitive resolution has not emerged. We present three studies that collectively demonstrate that the computations underlying this phenomenon are low-level, instantiated prior to binocular fusion, and available innately, without need for inferential learning via an individual's visual experience. In our first two studies, we find that strong brightness induction is obtained even when observers are unaware of any luminance differences in the neighborhoods of the probe patches. Results with dichoptic displays reveal that eye of origin, although not evident consciously, has a marked influence on the eventual brightness percept of the probe patches, thereby localizing brightness estimation to a site preceding binocular fusion. The third study uses conventional simultaneous brightness contrast displays, but an unusual group of participants Congenitally blind children whom we were able to treat surgically. The results demonstrate an immediate susceptibility to the simultaneous brightness illusion after sight onset. Together, these data strongly constrain the search for mechanisms underlying a fundamental brightness phenomenon.Objectives Our goal was to analyse all lead extraction procedures (transvenous or open surgery) performed in our centre and the short- and long-term follow-up data from these patients. Methods All lead extractions performed from 2008 to 2017 were retrospectively reviewed for patient characteristics and indications for device implantation; indications for lead extraction; techniques used; peri- and postprocedural complications and short- and long-term follow-up data. Results A total of 159 patients (282 leads) were included [age 70 (62-78) years; 72% men]. The median follow-up time was 57 (25-90) months. Patients with lead explants were excluded. The most common indication for lead removal was infection (77%). A surgical approach was necessary in 14 patients (9%) owing to unsuccessful transvenous removal (n = 3), large vegetation in the lead (n = 4), concomitant valvular endocarditis (n = 2), other indications for open surgery (n = 4) and complicated transvenous removal (n = 1). Removal was tried for 282 leads.
