The research aims to show the impact of financial engineering on the capital market development. The financial system has witnessed many changes that has stimulated financial engineering growth, which has contributed to the boost of capital market. This paper reports a theoretical examination that simultaneously considers the effects of the relationships between financial engineering and the development of the capital market, including the effect of financial engineering instruments in the boost of capital market and its efficiency. In addition to the impact of financial engineering in risk management. It encapsulates also the impact of technological advance and financial innovation in promoting capital markets.

Background: Urinary tract infection (UTI) has been a major burden on the community and the health-care systems all over the globe. It is the most common cause of bacterial infection in the pediatric age group, with an annual incidence of 3%. The aim of this study is to review and summarize all available guidelines on the diagnosis and management of children with UTI. Materials and Methods: This is a narrative review of the management of children with a UTI. All biomedical databases were searched, and any guidelines published from 2000 to 2022 were retrieved, reviewed, and evaluated to be included in the summary statements. The sections of the articles were formulated according to the availability of information in the included guidelines. Results: UTI diagnoses are based on positive urine culture from a specimen of urine obtained through catheterization or suprapubic aspiration, and diagnoses cannot be established on the bases of urine collected from a bag. The criteria for diagnosing UTI are based on the presence of at least 50,000 colony-forming units per milliliter of a uropathogen. Upon confirmation of UTI, the clinician should instruct parents to seek rapid medical assessment (ideally within 48 h) of future febrile disease to ensure that frequent infections can be detected and treated immediately. The choice of therapy depends on several factors, including the age of the child, underlying medical problems, the severity of the disease, the ability to tolerate oral medications, and most importantly local patterns of uropathogens resistance. Initial antibiotic choice of treatment should be according to the sensitivity results or known pathogens patterns with comparable efficacy of oral and parenteral route, for 7 days to 14 days duration. Renal and bladder ultrasonography is the investigation of choice for febrile UTI, and voiding cystourethrography should not be performed routinely unless indicated. Conclusion: This review summarizes all the recommendations related to UTIs in the pediatric population. Due to the lack of appropriate data, further high-quality studies are required to improve the level and strength of recommendations in the future.

Aim To assess the mediating role of emotion regulation and emotional intelligence in the relationship between stress and academic engagement among Saudi undergraduate nursing students. Design This study employed a quantitative cross‐sectional research design. Methods The study recruited 367 Saudi undergraduate nursing students at a major Saudi university. Structural equation modelling was used to explore the mediational model. Results The results of the ANOVA and Welch F‐test demonstrated that the emotional intelligence, emotional regulation and academic engagement scores were statistically significantly different according to stress levels (p‐values <0.01). Perceived stress has a statistically significant moderate negative correlation with academic engagement and emotional intelligence and a strong negative correlation with emotional regulation. The results also showed that academic engagement had a statistically significant moderate positive association with emotional intelligence and emotional regulation. Results indicate that stress and academic engagement are negatively correlated among Saudi undergraduate nursing students. It focuses on the balancing functions of emotional regulation and emotional intelligence, highlighting their ability to lower stress levels and improve academic engagement.
