Overall the AR module was better received compared with the control group with regards to realism, identifying landmarks, visualization of internal organs, ease of use, usefulness, and promoting learning and understanding.

The aims of this study were to investigate the demographics, causes, and contributing factors of retained guidewires (GWs) and to make specific recommendations for their prevention. Methods:The Veterans Administration patient safety reporting system database for 2000-2016 was queried for cases of retained GWs (RGWs). Data extracted for each case included procedure location, provider experience, insertion site, urgency, time to discovery, root causes, and corrective actions taken.Results: There were 101 evaluable cases of RGWs. Resident trainee (36%), critical care unit (38%), femoral vein (44%), and nonemergent placement (79%) were the conditions most frequently associated with a RGW. While discovery occurred almost immediately (30%) or in next 24 hours (31%), there were instances of RGWs found months (2%) or years (3%) later. Common root causes included inexperience (46%), lack of standardization (35%), distractions (25%), and lack of a checklist (23%). Conclusions:The results demonstrate the result of human factors-based errors such as posttask completion errors. We recommend human factorbased interventions such as checklists and devices employing forcing functions that do not allow clinicians to complete the insertion process without first removing the GW.

Purpose: The purpose of this study was to determine the ultimate body mass, performance, and nutritional characteristics of the Algerian judo junior athletes, and also analysing the impact of nutritional intakes on stabilising Weight loss according to special performance of judo athletes. Material: Twenty-one male university athletes (aged: 21.45 ± 1.32; height: 1.81 ± 0.45 m; and body mass: 73.9 ± 4.1 kg) participated in this study during a period of stabilising Weight loss before and after 15 days of caloric restriction. Athletes were submitted to anthropometrical measurements and performed the Special Judo Fitness Test. Values for nutrient intakes were obtained from a 15 day food record kept during a training camp period of Weight maintenance and after a 15-day caloric restriction. Results : caloric restriction resulted in significant decreases in body mass (73.73 ± 2.1) and performance. However, Special Judo Fitness Test index increased significantly (14.00 ± 1.75) during caloric restriction in comparison to stabilising Weight loss. Conclusion: Exercise and caloric restriction lead to determine the ultimate Weight and physical performance. The present study provides baseline nutritional data that can be used in the prescription of individual training programs for university judo Athletes.
