Background: The subcallosal artery (ScA) is a single dominant artery arising from the anterior communicating artery. Its injury causes amnesia and cognitive disturbance. The conventional computed tomographic angiography (C-CTA) is a common evaluation method of the intracranial artery. However, to image tinny perforating arteries such as the ScA is technically demanding for C-CTA. The purpose of this study is to investigate whether the ultra-high-resolution CTA (UHR-CTA) could image the ScA better than C-CTA. UHR-CTA became available in clinical practice in 2017. Its novel features are the improvement of the detector system and a small X-ray focus. Methods: Between April 2019 and May 2020, 77 and 49 patients who underwent intracranial UHR-CTA and C-CTA, respectively, were enrolled in this study. Two board-certified neurosurgeons participated as observers to identify the ScA based on UHR-CTA and C-CTA images. Results: UHR-CTA and C-CTA detected the ScA in 56–58% and 30–40% of the patients, respectively. In visualization of the ScA, UHR-CTA was better than C-CTA (P < 0.05, Fisher’s exact test). Between the two observers, the Cohen’s kappa coefficient was 0.77 for UHR-CTA and 0.78 for C-CTA. Conclusions: UHR-CTA is a simple and accessible method to evaluate intracranial vasculature. Visualization of the ScA with UHR-CTA was better than that with C-CTA. The high quality of UHR-CTA could provide useful information in the neurosurgery field.

Hierarchy Process

There are two major problems in the evaluation of the teaching quality of English writing: the weak logic of the evaluation system and the low reliability of the evaluation model. To solve the problems, this paper put forward an evaluation method for the teaching quality of English writing based on the analytical hierarchy process (AHP). Firstly, the authors reviewed the current evaluation methods for the teaching quality of English writing. Next, hierarchical evaluation systems were established for the teaching quality of English writing from the perspectives of teachers and students, respectively. After that, the AHP method and the grey theory were introduced to set up an evaluation model for the teaching quality of English writing. Finally, several strategies were presented to improve the teaching quality of English writing. The proposed evaluation systems and model enriched the theories on teaching quality evaluation of English writing, and promoted the teaching quality of English writing.

Objective.Nontraumatic osteonecrosis (ON) is a well-recognized complication causing disability and affecting quality of life in patients with systemic lupus erythematosus (SLE). The aim of this study was to identify the risk factors for ON, and to identify the minimal investigation(s) needed to optimally monitor the risk of ON in patients with SLE.Methods.A systematic review was conducted using MEDLINE and EMBASE. These databases were searched up to January 2016 using the Medical Subject Heading (MeSH) terms “Osteonecrosis,” “Systemic lupus erythematosus,” and synonymous text words. Randomized controlled trials, case control, cohort, and cross-sectional studies were included. Risk factors for ON in patients with SLE were compiled. The quality of each study was assessed using the Newcastle-Ottawa scale for nonrandomized studies. The quality of evidence of each risk factor was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation method.Results.Of the 545 references yielded, 50 met inclusion criteria. Corticosteroid (CS) use may be strongly associated with ON in patients with SLE. Other clinical variables were moderately associated, including hypertension, serositis, renal disease, vasculitis, arthritis, and central nervous system disease. However, the evidence was low to very low in quality.Conclusion.Based on the best evidence available, CS use may be strongly associated with ON in patients with SLE. Results of this review were considered in the development of recommendations for the diagnosis and monitoring of patients with SLE in Canada and will guide clinicians in their assessment of these patients.

Основной задачей для обеспечения качества функциональных продуктов длительного хранения является наличие методов оценки срока годности, применение которых позволит оценить не только качество продукта, но и его функциональные свойства на протяжении всего срока годности продукта. В настоящее время установлена возможность разработки методики ускоренного хранения для функциональных продуктов на молочной основе длительного хранения с применением метода ASLT и математического моделирования, исходя из имеющихся наработанных статистических данных по показателям окислительной порчи, содержанию свободных аминокислот и параметрам оценки продуктов гидролиза белка. В данной работе приведена оценка роли органолептического анализа при подтверждении срока годности продукции, рассмотрены основные процессы, влияющие на изменение органолептических характеристик при хранении. По результатам выполненной работы даны рекомендации по использованию метода органолептической оценки применительно к функциональным продуктам на молочной основе при использовании методики ускоренного хранения. The main task for ensuring the quality of functional shelf-stable products is the availability of methods for assessing the shelf life, the use of which will allow not only assessing the quality of the product, but also its functional properties throughout the entire shelf life of the product. Currently, the possibility of developing a method of accelerated storage for functional milk-based products for long-term storage using the ASLT method and mathematical modeling has been established, based on the available accumulated statistical data on indicators of oxidative spoilage, the content of free amino acids and parameters for evaluating protein hydrolysis products. This work evaluates the role of organoleptic analysis in confirming the shelf life of products, considers the main processes that affect the change in organoleptic characteristics during storage. Based on the results of the work performed, recommendations were given on the use of the method of organoleptic assessment in relation to functional milk-based products when using the accelerated storage method.

AbstractWith the continuous development of testing and evaluation of tidal current convertors, power quality assessment is becoming more and more critical. According to the characteristics of Chinese tidal current power generation and power quality standards, this paper proposes a comprehensive evaluation method of power quality based on K-means clustering and a support vector machine. The fundamental purpose of the method is to automatically select the weights of various indicators in the comprehensive assessment of power quality, by which the influence of subjective factors can be eliminated. In order to achieve the above purpose, K-means clustering is used for automatically classifying the operational data into five different categories. Then, a support vector machine is used to study and estimate the relationship of the operational data and categories. Using the method proposed in the paper, the analysis of operational data of a tidal current power generation shows that calculation results can objectively reflect the power quality of the device, and the influence of subjective factors is eliminated. The method can provide a reference for the testing and evaluation of a large amount of tidal current convertors in the future.

Background Associations between the quality of nursing care and patient outcomes have been demonstrated globally. However, translation and application of this evidence to robust measurement in pediatric specialty nursing care has been limited. Objectives To test the feasibility and performance of nurse-sensitive measures in pediatric cardiovascular programs. Methods Ten nurse-sensitive measures targeting nursing workforce, care process, and patient outcomes were implemented, and measurement data were collected for 6 months across 9 children’s hospitals in the Consortium of Congenital Cardiac Care–Measurement of Nursing Practice (C4-MNP). Participating sites evaluated the feasibility of collecting data and the usability of the data. Results Variations in nursing workforce characteristics were reported across sites, including proportion of registered nurses with 0 to 2 years of experience, nursing education, and nursing certification. Clinical measurement data on weight gain in infants who have undergone cardiac surgery, unplanned transfer to the cardiac intensive care unit, and pain management highlighted opportunities for improvement in care processes. Overall, each measure received a score of 75% or greater in feasibility and usability. Conclusions Collaborative evaluation of measurement performance, feasibility, and usability provided important information for continued refinement of the measures, development of systems to support data collection, and selection of benchmarks across C4-MNP. Results supported the development of target benchmarks for C4-MNP sites to compare performance, share best practices for improving the quality of pediatric cardiovascular nursing care, and inform nurse staffing models.
