Besides providing information to pupils, their parents, teachers, and school founders about the achieved level in mathematics, the pupils’ results in mathematics at international or national testing can also be used for other purposes. In our research, the results of Slovak national testing T9 (success rate of pupils and difficulty of individual thematic areas and test items) seem to us to be a reasonable source for identification of critical areas in school mathematics. Based on the findings of such areas, we target more at these areas in the preparation of future teachers of mathematics. The special group of problems, so-called problems with figures, seems to be one of the critical areas. In the assignment of these problems, a part of the input information is not of a purely textual character, and in the process of solving the solver has to read information about objects appearing in the problem and relations between objects from figures (e. g. scheme, graph, chart, table, picture or map). The paper focuses on success rates of pupils in solving problems of this type and on various roles and functions of figures in problems with figures from the testing T9.

Introduction: Prehospital tracheal intubation of a difficult airway is challenging for paramedics. Thus far, the potential role of video laryngoscopes for this purpose has not been confirmed. Therefore, this study aimed to determine the impact of different types of video laryngoscopes on the success rate and time to intubation by paramedics. Methods: This is a prospective, randomized, crossover manikin study involving 18 paramedics. Participants performed intubation on a difficult airway in a high-fidelity manikin using Pentax-AWS®, Glidescope®, and King Vision® (with two blade types). Time to intubation and success rate of intubation were determined. Participants also rated the best glottic view and reported their preferences of devices. Results: In a difficult-airway scenario, the median time to intubation with Pentax-AWS® was 22.9 s (interquartile range, 19.5–24.9 s), which was significantly shorter than using other devices. There were no significant differences in the time to maximal exposure of the vocal cords between four devices ( p = 0.156). The time to insert the endotracheal tube with Pentax-AWS® and King Vision® with a guide-channel blade was significantly shorter than that with the other two devices (all, p < 0.05). Pentax-AWS® and King Vision® with a guide-channel blade showed higher success rates than the other two devices ( p = 0.04). With regard to device preference, 14 participants preferred Pentax-AWS® among all devices analyzed. Conclusion: Pentax-AWS® could be an appropriate device for paramedics in cases of difficult airways, with high success rate.

This article focuses on the decision-making processes involved in research and knowledge integration in translation processes. First, the relevance of decision taking intranslation is discussed. Second, the psychology of decision making as seen by Jungermann et al. (2005) is introduced, who propose a categorization of decision-making processes intofour types: “routinized”, “stereotype”, “reflected” and “constructed”. This classification is then applied to the translations by five professional translators and five novices of five segments occurring in a popular-science text. The analysis reveals that the decision-making types are distributed differently among students and professional translators, which also has to be seen against the background of whether the decisions made were successful or not. The preliminary results of this study show that students resort to reflected decisions in most cases, but with a low success rate. Professionals achieve a higher success rate when making reflected decisions. As expected, they also make more routinized decisions than students. The professionals’ success rates improve with increasing cognitive involvement, while their failure rates are relatively high when making routinized decisions, an aspect worthwhile considering in translation didactics.

Abstract Background Gastrointestinal tumor bleeding remains a clinical challenge because it is difficult to treat with conventional endoscopic hemostatic options. Recently, an endoscopic hemostatic powder (UI-EWD) was developed and reported to provide effective control of upper gastrointestinal bleeding. The aim of current study was to evaluate the feasibility and efficacy of this novel hemostatic powder in tumor bleeding. Methods A total of 41 consecutive patients with upper gastrointestinal tumor bleeding were included. UI-EWD was applied in all patients as an auxiliary hemostatic method as a salvage therapy or monotherapy during endoscopic treatment. Hemostasis success rates, adverse event related to UI-EWD, and rates of re-bleeding were evaluated. Results In all cases, UI-EWD application was successful at tumor bleeding sites. Immediate hemostasis occurred in 40/41 (97.5%) patients, and re-bleeding within 28 days occurred in 10 of 40 (22.5%) patients that achieved initial hemostasis. The success rate of immediate hemostasis for UI-EWD monotherapy was 100% (23/23). The re-bleeding rate at 28 days after UI-EWD monotherapy was 26.1% (6/23). No adverse events associated with UI-EWD application were encountered. Conclusions The success rate of UI-EWD for immediate hemostasis in cases of GI tumor bleeding was excellent and UI-EWD produced promising results with respect to the prevention of re-bleeding. Based on these results, we suggest that UI-EWD be considered an effective salvage therapy or even monotherapy for GI tumor bleeding.

Abstract Aim This systematic review and meta-analysis aims to assess this relationship and determine the most appropriate age for recommendation of surgery. Method According to the “Preferred Reporting items for systematic review and meta-analysis” (PRISMA) statement, a literature search was performed across Medline, EMBASE and the Cochrane library from 1946-2018. Articles examining a relationship between age and myringoplasty or type 1 tympanoplasty success rates were screened. Results 20 articles encompassing data from 2244 procedures were included. The overall results conveyed a clear correlation between increasing age and rising success rate. A t-test was conducted which demonstrated a significant (P = 0.05) transition at aged 10, whereby success rate below age 10 was 70.6% and above 10 was 86%. Conclusions This systematic review and meta-analysis has uncovered a clear correlation between increasing age and increasing success rate for myringoplasty in the paediatric population. Furthermore, a significant transitional point has been demonstrated at the age of 10 and We hope that knowledge of increased success rates particularly after the age of 10 helps clinicians make more informed decisions about when to operate

BackgroundIt is generally recommended to keep the wrist joint mildly dorsiflexed during radial artery catheterisation. However, wrist dorsiflexion might decrease the success rate of radial artery catheterisation with dynamic needle tip positioning technique. Therefore, we assessed the success rates of two groups with or without wrist dorsiflexion by 5 cm wrist elevation in adult patients.MethodsThis randomised controlled clinical trial was performed between March and December 2018 in the First Affiliated Hospital of Shantou University Medical College, China. We recruited 120 adult patients undergoing major surgical procedures and randomly allocated them into two groups: dorsiflexion group (group D) and neutral group (group N). The primary outcome was first-attempt success rates of two groups. Secondary outcomes were overall success rates within 5 min; numbers of insertion and cannulation attempts; overall catheterisation time; duration of localisation, insertion and cannulation; and complication rates of catheterisation.ResultsFirst-attempt success rate was 88.3% in group D and 81.7% in group N (p=0.444). The overall success rate within 5 min was 93.3% in group D compared with 90.0% in group N (p=0.743). Numbers of insertion and cannulation attempts, overall catheterisation time, duration of localisation and insertion, and complication rates did not show a significant difference between the two groups. Cannulation time was longer in group N (35.68 s) than that in group D (26.19 s; p<0.05).ConclusionWrist dorsiflexion may not be a necessity for ultrasound-guided radial artery catheterisation using dynamic needle tip positioning technique in adult patients.Trial registration numberChiCTR1800015262.

AbstractIn this article, we present the genomic DNA yield and the microsatellite and single nucleotide polymorphism (SNP) genotyping success rates of genomic DNA extracted from a large number of mouth swab samples. In total, the median yield and quality was determined in 714 individuals and the success rates in 378,480 genotypings of 915 individuals. The median yield of genomic DNA per mouth swab was 4.1 μg (range 0.1–42.2 μg) and was not reduced when mouth swabs were stored for at least 21 months prior to extraction. A maximum of 20 mouth swabs is collected per participant. Mouth swab samples showed in, respectively, 89% for 390 microsatellites and 99% for 24 SNPs a genotyping success rate higher than 75%. A very low success rate of genotyping (0%–10%) was obtained for 3.2% of the 915 mouth swab samples using microsatellite markers. Only 0.005% of the mouth swab samples showed a geno-typing success rate lower than 75% (range 58%–71%) using SNPs. Our results show that mouth swabs can be easily collected, stored by our conditions for months prior to DNA extraction and result in high yield and high-quality DNA appropriate for genotyping with high success rate including whole genome searches using microsatellites or SNPs.

Background: Machine Learning (ML) has experienced an increasing use given the possibilities to expand the scientific knowledge of different disciplines, such as nanotechnology. This has allowed the creation of Cheminformatic models, capable of predicting biological activity and physicochemical characteristics of new components with high success rates in training and test partitions. Given the current gaps of scientific knowledge and the need of efficient application of medicines products law, this paper analyzes the position of regulators for marketing medicinal nanoproducts in European Union and the role of ML in the authorization process. Methods: In terms of methodology, a dogmatic study of the European regulation and the guidances of the European Medicine Agency on the use of predictive models for nanomaterials was carried out. The study has, as the framework of reference, the European Regulation 726/2004 and has focused on the analysis of how ML processes are contemplated in the regulations. Results: As result, we present a discussion of the information that must be provided for every case for simulation methods. The results show a favorable and flexible position for the development of the use of predictive models to complement the applicant's information. Conclusion: It is concluded that Machine Learning has the capacity to help to improve the application of nanotechnology medicine products regulation. Future regulations should promote this kind of information given the advanced state of art in terms of algorithms that are able to build accurate predictive models. This especially applies to methods such as Perturbation Theory Machine Learning (PTML), given that it is aligned with principles promoted by the standards of Organization for Economic Co-operation and Development (OECD), European Union regulations and European Authority Medicine. To our best knowledge this is the first study focused on nanotechnology medicine products and machine learning use to support technical European public assessment report (EPAR) for complementary information.

Abstract Introduction: Securing the airway is a crucial stage of trauma care. Cricothyroidotomy (CRIC) is often addressed as a salvage procedure in complicated cases or following a failed endotracheal intubation (ETI). Nevertheless, it is a very important skill in prehospital settings, such as on the battlefield. Hypothesis/Problem: This study aimed to review the Israel Defense Forces (IDF) experience with CRIC over the past two decades. Methods: The IDF Trauma Registry (IDF-TR) holds data on all trauma casualties (civilian and military) cared for by military medical teams since 1997. Data of all casualties treated by IDF from 1998 through 2018 were extracted and analyzed to identify all patients who underwent CRIC procedures. Variables describing the incident scenario, patient’s characteristics, injury pattern, treatment, and outcome were extracted. The success rate of the procedure was described, and selected variables were further analyzed and compared using the Fisher’s-exact test to identify their effect on the success and failure rates. Odds Ratio (OR) was further calculated for the effect of different body part involvement on success and for the mortality after failed ETI. Results: One hundred fifty-three casualties on which a CRIC attempt was made were identified from the IDF-TR records. The overall success rate of CRIC was reported at 88%. In patients who underwent one or two attempts, the success rate was 86%. No difference was found across providers (physician versus paramedic). The CRIC success rates for casualties with and without head trauma were 80% and 92%, respectively (P = .06). Overall mortality was 33%. Conclusions: This study shows that CRIC is of merit in airway management as it has shown to have consistently high success rates throughout different levels of training, injuries, and previous attempts with ETI. Care providers should be encouraged to retain and develop this skill as part of their tool box.

Background: Grown-up congenital heart disease (GUCH) patients are unique and challenges especially at developing country. The numbers of diagnostic as well as interventional cardiac catheterization procedures in GUCH patients are growing. The aim of this study was to report the outcome of cardiac catheterization including intervention procedure in GUCH.Methods: The descriptive study was conducted at Sanglah Hospital, Denpasar, Bali, Indonesia. All patients (age of more than 12 years) who underwent cardiac catheterization from 2011 until 2017 were included in this study. Patients, characteristic, types of catheter procedures, immediate complications, and outcomes were documented.Results: A total 54 subjects were included with median age of 23 years and 70% were female. The first symptom that brought patients to hospital is dyspnea 46% and palpitation 32%. Five subjects underwent a diagnostic catheter procedure and 49 (91%) diagnostic and catheter based interventions. Transcatheter interventions procedures included atrial septal defect (ASD) (success rate of 20 per 21), patent ductus arteriosus (PDA) (success rate of 16 per16), ventricular septal defect (VSD) (success rate of  9 per 9), pulmonal stenosis (PS) (success rate of 1 per 2), and aortic stenosis (AS) (success rate of 1 per 1). The complications encountered were transient dysrhythmias in 15 subjects, device embolization in 4 subjects, massive bleeding in 1 subject, and overall mortality in 2 subjects.Conclusion: The number of the catheterization interventions in GUCH was 91% and ASD device closure was the most common procedure. Transcatheter intervention has a high procedural success rates (96%) and low procedural-related complications.
