DAPT typically includes aspirin and a P2Y12 inhibitor and is used to mitigate complications from cardiovascular atherosclerotic disease. The article details the pharmacological profiles of common antiplatelet agents. Evidence from randomized controlled trials informs DAPT's application in various clinical contexts, demonstrating clear benefits in chronic coronary syndrome and acute coronary syndrome. However, its role in primary prevention is unproven. The review highlights the need for individualized treatment strategies, particularly concerning the duration of therapy following procedures like percutaneous coronary intervention, coronary artery bypass grafting and post transcatheter aortic valve implantation. Considering the ubiquitousness of these medications clinicians should be aware of the underlying induction, and evidence surrounding their use. Ongoing research is essential to refine antiplatelet strategies, ultimately improving patient outcomes while minimizing adverse effects.

{"title":"Enhancing Surgical Skill Acquisition: Assessment of a Novel 3D Printed Laparoscopic Trainer (Non-Inferiority Trial).","authors":"Olivia Heinecke, Lisa MacFadden","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>As laparoscopic operations yield reliable outcomes across specialties, the need for specialized skills underscores the importance of effective, accessible, and affordable training devices. The acquisition of these techniques is typically tied to hands-on instruction in the operating theater or simulation labs that house costly training equipment. Outside of these opportunities, student exposure is limited to observation. Current literature describes \"do-it-yourself\" trainers that attempt to mitigate costs; however, material pricing, ease of use, and simulation realism can still be improved. This study aims to validate a novel 3D (three dimensional)-printed laparoscopic trainer designed to provide training outcomes comparable to those of commercial simulators at a fraction of the cost. In this IRB-approved study, we designed a 3D-printed laparoscopic trainer prioritizing affordability, portability, and accessibility. Our device was modeled using Autodesk Fusion 360 software and printed with PLA (polylactic acid) material. To test its functionality, twenty medical students (M1-M4) with no prior laparoscopic training were randomized into two groups to train on either a commercial simulator (SIMULAB LapTrainer) or the 3D-printed trainer. Participants were taught a threading technique and timed on task completion before and after a one-hour training session. A paired one-sided t-test revealed no significant differences in task completion times between the two devices for both pre-training (p > 0.05) and post-training (p > 0.05) trials, indicating comparable effectiveness. Additionally, all participants demonstrated improved task completion times in their post-training trials. These findings validate the potential of 3D-printed trainers as cost-effective alternatives for basic aparoscopic skills training. Future iterations will focus on improving ergonomics and realism to better replicate surgical environments, promote wider accessibility, and advance medical education in resourcelimited areas.</p>","PeriodicalId":39219,"journal":{"name":"South Dakota medicine : the journal of the South Dakota State Medical Association","volume":"78 suppl 5","pages":"s20"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144477121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
