A Comparative Study on the Results of College English Grade 4 Based on Multi-model Prediction
Authors: Yanwen Chen  
Published: May 2024

Predictive analytics improves educational outcomes by offering insights into student performance and influencing targeted interventions. In this work, we undertake a detailed comparative analysis of predictive models for projecting College English Grade 4 exam results, to contribute to the improvement of educational predictive analytics. We compare the predicted accuracy and interpretability of several modeling approaches, including ensemble learning methods like Random Forests, interpretable models like Decision Trees, and Support Vector Machines (SVM). We evaluate each model's performance using important metrics such as Mean Squared Error (MSE), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and R-squared (R2) coefficients. Our results show that Random Forests have greater prediction accuracy, beating other models in terms of MSE, RMSE, and MAE. Despite its slightly lower R2 coefficients, Decision Trees perform competitively and provide useful insights into crucial variables. In contrast, SVM shows limitations in prediction accuracy for College English Grade 4 exam results. We highlight the relevance of these findings for educators and administrators, emphasizing the need to make educated decisions when selecting predictive models and implementing targeted interventions to promote student achievement. This work advances the field of educational predictive analytics by giving empirical evidence for the efficacy of various modeling methodologies and emphasizing the importance of model interpretability in understanding student performance determinants. More study is needed to improve predictive analytics methods and enhance their applicability in educational settings.

Background This study is a systematic review of barriers and facilitators of supply-side maternal, newborn, and child health (MNCH) service availability in the Democratic Republic of the Congo (DRC). Given gaps in understanding of the factors affecting supply-side service availability, authors reviewed the literature to describe the DRC’s landscape and inform future research and programming. Methods Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, authors searched two databases and grey literature, using the Quality Assessment with Diverse Studies tool to assess quality. Authors identified key themes and used a narrative approach to analyze extracted data. Results The search identified 2160 articles, with 26 meeting the inclusion criteria. Authors grouped them according to the following key themes: facility readiness, human resources for health (HRH), geography and transportation, conflict, financing, and governance. MNCH service availability was hindered by lack of supplies, logistical challenges, weak infrastructure, unmet staffing needs, HRH turnover, poor HRH distribution, career and payment obstacles, long distances to facilities and poor transportation, system strain and disruption due to conflict, low government expenditure, high out of pocket costs, fragmented stakeholders, and low government prioritization. Authors found facilitating factors in each key theme, including parallel supply chains and buffer stocks, proactive staffing policies, motivated HRH, novel transportation methods, health posts, concentrations of stakeholders in conflict zones, universal health coverage policies, provider payment reforms, stakeholder coordination, and horizontal integration efforts. Conclusions The DRC faces substantial supply-side barriers to MNCH service availability. Progress towards the Sustainable Development Goals and better MNCH outcomes requires additional work to build on existing facilitators and investments in service availability. Additional research on demand-side factors and quality of care could inform these efforts.

BACKGROUND
Congenital absence of the menisci is a rare anatomical variation characterized by the absence or underdevelopment of one or both menisci in the knee joint. The menisci are crucial in load distribution, joint stability, and shock absorption. Understanding the clinical presentation, diagnosis, and management of this condition is important for optimal patient care.
CASE SUMMARY
A 27-year-old male with a long-standing history of knee pain underwent diagnostic arthroscopy, revealing a congenital absence of the meniscus. The patient's clinical findings, imaging results, surgical procedures, and pertinent images are detailed. This case presents a unique aspect with the congenital absence of the meniscus, contributing valuable insights to the literature on rare anatomical anomalies.
CONCLUSION
This case of congenital absence of the menisci highlights the diagnostic challenges posed by rare anomalies. The diagnostic arthroscopy played a crucial role in identifying the absence of the meniscus and providing an explanation for the patient's persistent knee pain. The case underscores the importance of individualized treatment approaches, including physical therapy, for optimal management of rare meniscal anomalies. Further research is warranted to explore effective management strategies for the aforementioned cases and to expand our knowledge of these rare conditions.

IntroductionVascular complications are a rare but important risk factor for failure and loss of kidney graft, increasing the mortality of renal graft recipients.Case reportWe present the case of massive haemorrhage due to the rupture of the arterial anastomosis caused by <i>Candida albicans</i> infection in a 64-year old female kidney graft recipient managed with suprapubic iliofemoral bypass during emergency life-saving graft nephrectomy performed in our unit. The postoperative period was complicated by femoral vein thrombosis and intraabdominal fluid collection. After 33 days, with a well-functioning iliofemoral bypass, the patient was discharged to the nephrology unit. At the 12-month follow-up, the patient is functioning well, receiving nephrological care and haemodialysis treatment.ConclusionsRoutine fungal cultures of graft preservation fluid and radiological follow-up in high-risk patients after transplantation may be helpful in the prevention of fatal complications in the high-risk patient group – especially if digestive tract injury occurred during organ harvesting. Nevertheless, histological examination remains the gold standard for the detection of fungal arteritis. Negative culture samples from the preservation fluid, blood and urine before the transplantation do not exclude the risk of fungal infection. Urgent allograft nephrectomy with resection and reconstruction of changed vessels seems to be the safest approach in ruptured anastomotic pseudoaneurysm, as shown in our case.

Authors: Wang Tian-Shu , Jing Li-Jun 
Published: May 2024

BACKGROUND
Cerebral infarction (CI) is characterized by a high prevalence, disability, and mortality. Timely or improper treatment greatly affects patient prognosis.
AIM
To explore the drug efficacy of aspirin plus edaravone and to explore their effect on quality of life (QOL), anxiety and depression in CI patients.
METHODS
We retrospectively analyzed the records of 124 CI patients treated between June 2019 and February 2021 who were assigned to an observation group (OG) (combination therapy of aspirin and edaravone, 65 patients) or a control group (CG) (aspirin monotherapy, 59 patients). The therapeutic effects, pre- and posttreatment National Institutes of Health Stroke Scale (NIHSS) scores, activities of daily living, degree of cognitive impairment, protein levels of glial fibrillary acidic protein (GFAP), neuron-specific enolase (NSE) and S-100B, occurrence of adverse reactions, and serum high-sensitivity C-reactive protein (hs-CRP), interleukin (IL)-6 and tumor necrosis factor (TNF)-α were evaluated, detected and compared between the two groups. Finally, posttreatment QOL, anxiety, and depression were assessed by the Medical Outcomes Study 36- Item Short Form Health Survey Scale, Self-rating Depression Scale (SDS), and Self-rating Anxiety Scale (SAS), respectively.
RESULTS
Compared with the CG, the OG had markedly better therapeutic effects, greater improvements in activities of daily living, and better alleviation in cognitive dysfunction after treatment, as well as lower posttreatment NIHSS scores and serum NSE, GFAP, S-100B, hs-CRP, IL-6, and TNF-α levels; the OG was similar to the CG in terms of adverse reactions but was better than the CG in terms of posttreatment QOL; and the OG also had lower SDS and SAS scores than the CG after treatment.
CONCLUSION
Aspirin plus edaravone had a good curative effect on CI. It can reverse cranial nerve damage in patients, improve neurological function and prognosis, and alleviate inflammation, anxiety, and depression; thus, it is considered safe and worthy of clinical application.

Utilizing Space Syntax Techniques to Understand the Relationship Between Spatial Configuration and Walkability in Urban Neighborhoods (Case Study: Valiasr Neighborhood, Tehran)
Authors: Shakibamanesh Amir , Karimian Bahar 
Published: May 2024

The numerous benefits of walking, as one of the healthiest, simplest, and most cost-effective modes of transportation, have prompted many urban researchers to identify influential factors in pedestrian-oriented urbanism. These efforts aim to transform urban areas, including neighborhoods, into conducive environments for walking, thereby realizing related benefits such as sustainable development. Extensive research has confirmed the role of the built environment in attracting and distributing pedestrian movement, with a significant portion highlighting the relationship between urban configuration and walkability. This study aims to determine the role of urban configuration components in enhancing walkability at the neighborhood scale, selecting the Valiasr neighborhood in Tehran due to its location in the city’s commercial center with a high volume of pedestrian traffic. For this purpose, after identifying spatial configuration components related to walkability – including accessibility, connectivity, and spatial arrangement components – key streets in the neighborhood's spatial configuration were identified using an initial analysis of spatial arrangement variables, followed by a survey of pedestrian volumes on selected streets. The evaluation of configuration components led to design recommendations in two layout patterns – grid and parallel block. The relationship between urban configuration and walkability, utilizing space syntax techniques, was identified after analyzing spatial arrangement variables in three different scenarios (existing condition and two proposed alternatives). The results indicate that accessibility components have the most significant impact on walkability in the Valiasr neighborhood. Following this, connectivity components were identified as influential in promoting pedestrian-oriented urbanism. Regarding spatial arrangement components, a comparison with prior research confirms that spatial elements do not operate independently of mixed-use and access to services and facilities. Instead, they play a role not in the formation of movement but in facilitating and directing it.
