AI Article Synopsis
- - The study aimed to validate a new training model using apple tissue for transurethral resection of the prostate (TURP) by assessing its face, content, and construct validity through participant evaluations and performance metrics.
- - Six consultants, three fellows, and 16 residents performed TURP on the apple model after watching a demo video, with results showing novices rated the model highly for realism, while experts demonstrated superior performance metrics indicating the model's effectiveness.
- - The findings confirmed that the apple-based model not only accurately simulates real TURP procedures, but also effectively distinguishes between the skills of expert and novice surgeons, establishing its validity for training purposes.
Article Abstract
Aims And Objectives: To establish face, content and construct validity of an innovative fruit-tissue (apple) based transurethral resection of prostate (TURP) training model devised at our institute.
Method And Material: Six consultants, three fellows and 16 residents performed TURP on the new fruit-tissue (apple) based TURP model for ten minutes after watching a demo-video. The procedure was videographed. At the end, participants answered a set of questionnaires regarding their experience. The video and the apple both were examined by blinded separate assessors based on pre-decided parameters. Statistical analysis was done to find out the face, content and construct validity of the training model.
Results: Participants were divided into two groups, expert and novice, based TURP surgery experience. The model was positively rated (lowest median value 4) by all novice for its 'realism' and 'acceptability'. The expert group also felt that the model reproduced real TURP experience (lowest median value 4). Thus, both face and content validity were established. The expert group resected more tissue (18.3±2.5 gm vs 10.3±3.4 gm; P<0.001) with less irrigation fluid (1566.6±187.0 ml vs 2112.5±344.2 ml; P<0.001) removing more chips (39.8±6.2 vs 25.6±3.0; P<0.001) and orientated themselves faster (63.3±12.2 sec vs 90.3±12.7 sec; P<0.001). The assessors' subjective evaluation of videos and apples both favored the experts. The model can differentiate 'expert' from 'novice', thus establishing 'construct validity'.
Conclusion: The new fruit-tissue (apple) based TURP model is a realistic and acceptable TRUP training model with proven face, content and construct validity.

Background: Facial aging involves multifactorial changes affecting the bone, superficial musculoaponeurotic system, fat pads, and skin, primarily manifesting as the downward displacement of these structures. The transtemporal endoscopic deep plane face lift (TEDPF) suggests a vertical lifting method, targeting these issues without a preauricular incision.
Methods: A retrospective study was conducted on 140 patients (133 women and 7 men) 33-67 years of age who underwent TEDPF from February 2020 to March 2023.

Introduction: The growing importance of mobile apps in osteoporosis management highlights the crucial need for evaluating their utility and usability, particularly for Osteoporosis support apps. Addressing this need, the mHealth App Usability Questionnaire (MAUQ) was crafted in four different versions, categorized based on the nature of the app (interactive or standalone) and the intended user (patient or provider). Due to its usage by diverse users with varying languages, this questionnaire requires psychometric assessment in multiple languages.

Background: Moral intelligence is a significant and influential factor in the delivery of principled and high-quality care. This is because moral intelligence is the ability to recognize and be sensitive to moral issues, which contributes to the organization of appropriate behavior in the face of moral issues. This is particularly pertinent given that pre-hospital emergency medical services personnel (prehospital EMS personnel) frequently encounter stressful and tension-filled situations.
