Our predictive model using "weighted" CUSUM analysis (a measure of performance over time) demonstrated that a predefined strategy of management of rAAA that includes EVAR is associated with improved (P < .05) mortality. Unstable patients with rAAA may be particularly benefited by EVAR and should not be excluded from repair. Appropriate patients with rAAA who are undergoing treatment in experienced vascular centers should be offered EVAR as the treatment of choice.
Poisoning is a medical emergency that represent a major health problem all over the world. Studies on drug overdose and chemical poisoning are very limited in Saudi Arabia (SA). We aimed to describe the current pattern and assess risk factors of drug overdose and chemical poisoning in King Khalid National Guard hospital, Jeddah, SA. Medical records of patients attended emergency department in King Khalid National Guard hospital during the period from January 2008 to December 2012 due to drug overdose and chemical poisoning were reviewed. A total of 129 cases were included in the study. The majority of the population was Saudi (97.7 %), and almost half of them were females (54.3 %). Children under 12 years were the most affected age group (44.2 %). Drug overdose was the most common cause of poisoning (92.2 %). Analgesics and non-steroidal anti-inflammatory drugs represented the highest percentage of used medications (20.4 %). The most commonly reported symptoms were symptoms of the central nervous system (57.4 %) followed by GIT symptoms (41.9 %). Intentional poisoning was reported in 34 cases (26.4 %). Female patients were significantly more likely to attempt suicide than male patients (OR = 7.22, 95 % CI = 1.70, 30.62). Children continue to be at high risk for medication and chemical poisoning. Accessibility to medications at homes encountered for most of poisoning cases among children. Implementing methods to raise public awareness and minimize children access to medications would significantly contribute to reducing burden of this problem on the community.
PurposeVarious smartphone-based virtual reality (VR) applications allow the users to view 360° videos of real or simulated places. A 360° VR is captured with a special camera that simultaneously records all 360° of a scene unlike the standard video recording. An experimental study was conducted where 4th-year medical students participated in a workshop.Patients and methodsThe study was conducted at College of Medicine (COM-J), King Saud bin Abdul-Aziz University for Health Sciences (KSAU-HS) in Jeddah, Saudi Arabia. 360° VR videos including, pre-briefing and debriefing sessions were held for the experimental group, whereas group two (control group) was provided with the interactive lecture. A total of 169 undergraduate medical students attend the 4th year at the College of Medicine (KSAU-HS) Jeddah.ResultsThe response rate was 88% for 169 participants, 57 (VR) and 112 (conventional method). The majority of students (93%) thought that VR can be used in medical education. Post-MCQs score (out of 20) was significantly higher in the VR group, when compared to the conventional group (17.4+2.1 vs 15.9+2.9, p-value <0.001). The OSCE score was also better with the VR group (12.9+4.1 vs 9.8+4.2, p-value <0.001). Overall rating of VR satisfaction experience showed a mean of 7.26 of 10.ConclusionVR provides a rich, interactive, and engaging educational context that supports experiential learning-by-doing. In fact, it raises interest and motivation for student and effectively supports knowledge retention and skills acquisition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
