In recent years, the country has taken several steps towards restructuring its organizational security and, consequently, protecting financial institutions and their clients. However, there are still several challenges left to be addressed. Accordingly, this article aims to address this problem by proposing an abstract framework based on the National Institute of Standards and Technology (NIST) Cybersecurity Framework and International Organization for Standardization/International Electrotechnical Commission (ISO/IEC 27001). The framework proposed in this paper considers the following factors involved in the security policy of Saudi banks: safety, Saudi information bank, operations and security of Saudi banks, Saudi banks’ supplier relationships, risk assessment, risk mitigation, monitoring and detection, incident response, Saudi banks’ business continuity, compliance, education, and awareness about all factors contributing to the framework implementation. This way, the proposed framework provides a comprehensive, unified approach to managing bank security threats. Not only does the proposed framework provide effective guidance on how to identify, assess, and mitigate security threats, but it also instructs how to develop policy and procedure documents relating to security issues.展开更多

文摘目的分析对肠易激综合征(Irritable Bowel Syndrome,IBS)患者用低可发酵的单糖、双糖、低聚糖和多元醇等饮食干预对胃肠道症状的影响。方法将2020年8月-2021年12月接收治疗的IBS患者78例作为观察对象,按照随机数字表法分为观察组(低FODMAP饮食)和对照组(常规饮食指导),比较两组分别干预后的病情严重程度调查表(Severity severity questionnaire,IBS-SSS)、日常生活能力量表(Activity of Daily Living Scale,ADL)、胃肠道症状改善时间(腹痛、腹泻、排便改变)。结果两组干预前的IBS-SSS比较并无统计学意义(P>0.05),干预后,观察组IBS-SSS评分(53.69±12.15)分相较对照组(85.45±11.12)分更低,对比有统计学意义(P<0.05),干预后,观察组胃肠症状改善时间包括排便(2.62±0.23)周、腹痛(1.72±0.23)周、腹泻(2.41±0.23)周时间更短,对比有统计学意义(P<0.05),两组干预前的ADL评分比较并无差异,无统计学意义(P>0.05),干预后,观察组ADL评分更高,对比有统计学意义(P<0.05)。结论低FODMAP饮食对IBS患者可缩短患者胃肠道症状改善时间,提高患者日常生活质量,减轻患者病情严重程度。

文摘噬菌体治疗作为抗生素治疗细菌感染的替代方法之一,近年来受到越来越多科学家们的关注,该法主要用于针对由耐药菌及多重耐药菌(Multi-drug resistant,MDR)引起的公共卫生安全问题。如今,噬菌体在农业和兽医治疗方面及其在西方国家用于人类治疗方面越来越受到重视,过去几十年西方世界进行了许多临床试验和治疗探索,并且国外某些授权药店正在销售人用噬菌体药物。但噬菌体用于人类治疗时仍然存在一些问题,如噬菌体的高度特异性限制了其应用范围和噬菌体制剂管理法规不完善使得其不能进行规模化生产等。本文结合我国现行药典关于生物制品生产、制备及质量控制要求和欧洲药品管理局(The European Medicines Agency,EMA)近年来以噬菌体治疗药物批准途径的探索为参照,着重对噬菌体库构建与控制、噬菌体制备与质控和临床前测试等进行分析。
