引用

Open Journal of Applied Sciences 2023年第10期13卷 1844-1854页

作者： Ahmed Abdulaziz Alburaidi Mohammed naif Albarakati Ahmed Khalid Sabr Mohammed Fadhy Alharbi Abdulaziz khalaf Alkhathami Nesreen Ayman Kurdi Department of Biomedical Engineering Prince Sultan Armed Forces Hospital Medina Saudi Arabia

In this research, the researchers addressed the issue of digital transformation and its impact on the development of medical maintenance, and this topic is very important in the field of medical engineering. The researchers chose the military Hospital in Medina as his study location. The study aimed to identify and address the main challenges facing the digital transformation of medical maintenance at the Military Hospital in Medina. It seeks to analyze the current state of digitalization in medical maintenance operations, identify areas requiring improvement, and propose effective strategies to overcome obstacles. The study will evaluate the impact of digital transformation on efficiency, cost-effectiveness, patient care, and overall operational performance. At the end of the research, the researchers reached several results, including that introducing digital systems and technologies into medical maintenance can increase efficiency in various aspects, such as scheduling equipment maintenance, inventory management, and resource allocation. Researchers may find evidence of reduced downtime, streamlined workflow, and optimized use of resources. In addition, digital transformation initiatives in medical maintenance may focus on ensuring the safety and reliability of medical equipment. Research can reveal improvements in equipment reliability, decreased equipment failure rates, and improved patient safety outcomes. The researchers also recommended developing a comprehensive strategy for digital transformation: Based on the research results, it is recommended to develop a well-defined strategy that defines the hospital’s vision, goals, and roadmap for the digital transformation of medical maintenance. This strategy should consider factors such as technology selection, resource allocation, timeline, and change management. Invest in a solid digital infrastructure: To support the digital transformation of medical maintenance, the hospital must invest in a reliable and secu

Irritable Bowel Syndrome and Dietary Habits in Northern Saudi Arabia

Health 2019年第3期11卷 289-297页

作者： Saleh Hadi Alharbi Fahad A. Alateeq Khalil Ibrahim alshammari Abdulaziz Saad Sharea Alshammri naif Abdulmohsen naif Alabdali Motab Ali Saud Alsulaiman Sami Mamdouh Ibrahim Algothi Abdulrahman Sulaiman Altoraifi Maha Qasem Almutairi Hussain Gadelkarim Ahmed Faculty of Medicine Al-Imam Mohammad Ibn Saud Islamic University Riyadh KSA College of Medicine University of Hail Hail KSA Department of Histopathology and Cytology FMLS University of Khartoum Khartoum Sudan

Background: dietary habit is one of the most universally recounted initiators of irritable bowel syndrome (IBS). The objective of the present study was to determine the role of some dietary habits in the etiology of IBS in Northern Saudi Arabia. Methodology: In this community based cross-sectional survey, data about IBS were obtained from 930 Saudi volunteers living in the city of Hail, Northern Saudi Arabia. IBS was diagnosed using Rome IV criteria. Results: The prevalence of IBS was 11% among males vs. 12.5% among females. The prevalence of IBS symptoms among males was 30% vs. 36.5% females. IBS was significantly associated with reduced water intake, the RR (95% CI) = 1.1800 (1.0146 to 1.3722), P = 0.0316. In the present study, the majority of the study population 904/929 (97.3%) didn’t accustom to vegetables/fruits intake. Conclusion: IBS is prevalent in Northern Saudi Arabia, both among males and females with relatively increasing among females. Low water intake and insufficient fibers intake (particularly, in vegetables and fruits) might be behind the growing prevalence of IBS in Saudi Arabia.
