Background Intravenous cannulation is usually the first procedure performed in modern healthcare, although establishing peripheral intravenous access is challenging in some patients. The impact of the ratio between venous diameter and the size of the inserted catheter (catheter to vein ratio, CVR) on the first attempt success rate can be of added value in clinical. This study tries to give insight into the consideration that must be made when selecting the target vein and the type of catheter, and proved the null hypothesis that an optimal CVR would not be associated with increased first attempt cannulation success. Methods This was a post-hoc analyses on adult patients admitted for peripheral intravenous cannulation. Intravenous cannulation was performed according to practice guidelines, by applying the traditional landmark approach. The CVR was calculated afterwards for each individual patient by dividing the external diameter of the inserted catheter by the diameter of the target vein, which was multiplied by 100%. Results In total, 610 patients were included. The median CVR was 0.39 (0.15) in patients with a successful first attempt, whereas patients with an unsuccessful first attempt had a median CVR of 0.55 (0.20) (P<0.001). The optimal cut-off point of the CVR was 0.41. First attempt cannulation was successful in 92% of patients with a CVR<0.41, whereas as those with a CVR>0.41 had a first attempt success rate of 65% (P<0.001). Conclusion This first introduction of the CVR in relation to cannulation success should be further investigated. Although, measuring the venous diameter or detection of a vein with a specific diameter prior to cannulation may increase first attempt cannulation success.

Aim: This study aimed to investigate the association between periampullary diverticulum (PAD) and difficult biliary cannulation, as well as to evaluate the impact of different types of PAD on the cannulation success rate and adverse events. Methods: A total of 636 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) during the study period were prospectively studied and divided into two groups based on the presence or absence of PAD. In group A, 126 patients had PAD compared with 510 patients in group B without PAD. The primary outcome measurements were ERCP procedures time, selective cannulation techniques, and cannulation difficulty in addition to cannulation success rate and ERCP-related adverse events. The difficult cannulation was analyzed using logistic regression considering age, co-morbidities, the presence of PAD types, and indications as independent factors. Results: The average cohort age was 65.30&plusmn;16.67 years, and 52.7% were male. Significant higher rates of choledocholithiasis, cholangitis, and biliary pancreatitis were reported in the group of PAD (p&lt;0.05). Successful selective cannulation was achieved in 97.6% in group A and 95.3% in group B (p&gt;0.05). The cannulation time was significantly longer in the presence of PAD (5.1 min, vs. 4.09 min, p&lt;0.05). There was no significant difference in the rate of overall adverse events and post ERCP pancreatic PEP. Conclusion: The presence of PAD did not affect the duration or success of the ERCP procedure. Furthermore, it was associated with longer cannulation time and increase in the cannulation difficulty, especially with PAD type 1.

Heart rate (HR) variability (HRV) is a useful tool for assessing cardiac autonomic function and identifying potential readiness to perform in athletic populations, but has yet to be investigated in dance populations. As such, HRV may be able to provide valuable insight into the preparedness of dancers and the demands of performance in a collegiate dance population. 29 female dancers were monitored leading up to and following a dance performance. Analysis of HRV focused on the square root of the mean squared differences of the successive RR intervals (RMSSD). A one-way ANOVA, with Bonferroni post-hoc, paired with magnitude-based-inferences (MBI) with effect sizes (ES) were used to analyze changes during the Winter Dance Concert, while the Recovery-Stress Questionnaire for Athletes (REST-Q Sport) measured the frequency of stress of dancers. When compared to baseline (69.8 ± 1.7 bpm), mean (HR) was increased at both pre-show recordings (76.5 ± 2.1 bpm and 75.6 ± 1.8 bpm). In contrast, RMSSD was significantly diminished (p < 0.05) at both pre-show recordings (40.6 ± 28.4 ms and 40.5 ± 21.8 ms) as compared to baseline (70.3 ± 38.4 ms). Dancers reported increased (p < 0.05) self-efficacy before the second show and at 36 h post-concert. As expected, Dance Exposure (DE) increased significantly (p < 0.05), while Academic Exposure (AE) was similar, during the week leading up to the dance concert. The results suggest dancers responded to concert dance performances similarly to other athletic populations approaching intense competition by exhibiting decreased parasympathetic activity prior to the dance performances, which returned to baseline values 36 h after their performances. Given the increase in self-efficacy, these fluctuations may indicate a readiness to a performance comparable to athletes.

The Impact

Introduction: Peripheral intravenous cannulation is the preferred method to obtain vascular access, but not always successful on the first attempt. Evidence on the impact of the intravenous catheter itself on the success rate is lacking. Faster visualization of blood flashback into the catheter, as a result of a notched needle, is thought to increase first attempt success rate. The current study aimed to assess if inserting a notched peripheral intravenous catheter will increase first attempt cannulation success up to 90%, when compared to inserting a catheter without a notched needle. Design: In this block-randomized trial, adult patients in the intervention group got a notched peripheral intravenous catheter inserted, patients in the control group received a traditional non-notched catheter. The primary objective was the first attempt success rate of peripheral intravenous cannulation. Intravenous cannulation was performed according to practice guidelines and hospital policy. Results: About 328 patients were included in the intervention group and 330 patients in the control group. First attempt success was 85% and 79% for the intervention and control group respectively. First attempt success was remarkably higher in the intervention group regarding patients with a high risk for failed cannulation (29%), when compared to the control group (10%). Conclusion: This study was unable to reach a first attempt success of 90%, although first attempt cannulation success was higher in patients who got a notched needle inserted when compared to those who got a non-notched needle inserted, unless a patients individual risk profile for a difficult intravenous access.

Abstract This essay will show, by the example of FWB-online (the online version of Frühneuhochdeutsches Wörterbuch), some possibilities to enhance the added value of traditional printed historical dictionaries published online by providing their data with deep structured semantic mark-up. This semantic mark-up can basically be used as a foundation for elaborated search and in a further advanced step also for visualizing specific aspects of the dictionary data, thus allowing for new perspectives on it. It will be shown, how these search methods and especially this kind of visualization of dictionary data can enable advanced approaches on both old and new scientific questions.

Purpose The purpose of this paper is to investigate the impact of five dimensions of experiential advertising (cognitive, emotional, sensory, relational and behavioural) on advertising credibility in the banking sector. Design/methodology/approach A total of 277 undergraduate students were asked to complete a questionnaire after viewing two versions of a bank advertisement. Results were analysed using structural modelling equations (EQS 6.2). Findings Findings show that all dimensions of experiential advertising positively impact advertisement credibility. Cognitive/emotional/sensory advertisements exert the greatest impact, followed by relational and then behavioural advertisements which have only a marginal impact. Post hoc results show that the impact of experiential advertising on advertising credibility varies according to both actor and respondent gender. Originality/value This study enhances the literature on experiential marketing and credibility, especially banking sector advertising, and provides more in-depth insight into the role of respondent and actor gender in influencing responses. Financial services practitioners would be well advised to devote particular attention to the formulation of experiential strategies when developing advertising campaigns.

SummaryAim: This study was performed to analyse the impact of the choice of antithyroid drugs (ATD) on the outcome of ablative radioiodine therapy (RIT) in patients with Graves' disease. Patients, material, methods: A total of 571 consecutive patients were observed for 12 months after RIT between July 2001 and June 2004. Inclusion criteria were the confirmed diagnosis of Graves' disease, compensation of hyperthyroidism and withdrawal of ATD two days before preliminary radioiodine-testing and RIT. The intended dose of 250 Gy was calculated from the results of the radioiodine test and the therapeutically achieved dose was measured by serial uptake measurements. The end-point measure was thyroid function 12 months after RIT; success was defined as elimination of hyperthyroidism. The pretreatment ATD was retrospectively correlated with the results achieved. Results: Relief from hyperthyroidism was achieved in 96 % of patients. 472 patients were treated with carbimazole or methimazole (CMI) and 61 with propylthiouracil (PTU). 38 patients had no thyrostatic drugs (ND) prior to RIT. The success rate was equal in all groups (CMI 451/472; PTU 61/61; ND 37/38; p=0.22). Conclusion: Thyrostatic treatment with PTU achieves excellent results in ablative RIT, using an accurate dosimetric approach with an achieved post-therapeutic dose of more than 200 Gy.
