We are told that AI learns, processes and creates, starting from fixed points to arrive at innovative solutions. In the case of scientific work, AI can generate data without ever having entered a laboratory, (i.e., blatantly plagiarizing the existing literature, a despicable old trick). How does an editor of a scientific journal recognize when she or he is faced with something like this? The solution is for editors and referees to rigorously evaluate the track records of submitting authors and what they are doing. For example, false color evaluations of 2D and 3D CT and MRI images have been used to validate functional electrical stimulation for degenerated denervated muscle and a home Full-Body In-Bed Gym program. These have been recently published in Ejtm and other journals. The editors and referees of Ejtm can exclude the possibility that the images were invented by ChatGPT. Why? Because they know the researchers: Marco Quadrelli, Aldo Morra, Daniele Coraci, Paolo Gargiulo and their collaborators as well! Artificial intelligence is not banned by the EJTM, but when submitting their manuscripts to previous and to a new Thematic Section dedicated to Generative AI in Translational Mobility Medicine authors must openly declare whether they have used artificial intelligence, of what type and for what purposes.

A literature search was conducted across PubMed, Scopus, and Web of Science, covering studies up to June 2024. Studies comparing PCI and CABG in patients with NSTE-ACS were included, focusing on clinical outcomes such as mortality, myocardial infarction, cerebrovascular accidents, and the need for repeat revascularization. Data extraction and quality assessment were performed. Statistical analysis was conducted using R software, with the Mantel-Haenszel method and random-effects model employed to pool effect sizes and assess heterogeneity. A total of 15 studies met the eligibility criteria, including 48,891 patients. The pooled risk ratio (RR) for mortality showed no significant difference between PCI and CABG (RR=1.09, 95% CI: 0.90-1.19, p=0.28). CABG was associated with a significantly lower risk of subsequent MI (RR=0.56, 95% CI: 0.38-0.61, p <0.01) and the need for repeat revascularization (RR=2.94, 95% CI: 2.30-3.76, p <0.01). Conversely, PCI had a lower associated risk of CVA (RR=0.58, 95% CI: 0.42-0.79, p <0.01). High heterogeneity was observed in mortality outcomes, indicating variability among studies. The findings suggest that while PCI and CABG have comparable mortality risks in NSTE-ACS patients, CABG offers superior protection against myocardial infarction and the need for repeat revascularization, whereas PCI is associated with a lower risk of cerebrovascular accidents. These results underscore the importance of individualized patient assessment in choosing the optimal revascularization strategy, considering patient-specific risk factors and clinical profiles.</p>","PeriodicalId":46459,"journal":{"name":"European Journal of Translational Myology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12038568/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142740913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time for groups' discussions and new collaborations are increased so as the job opportunities for the young researchers. The Padova Muscle Days have offered in the previous thirty-five years these opportunities, which have matured into innovative and multidisciplinary results to the point that it came naturally to underline it with a neologism now included in the title of the 2025 event: \"Mobility Medicine\", a discipline not yet officially recognised, that makes explicit the call for rejoining knowledges dispersed in sub-specialisations. The included program of the Padua Days on Muscle and Mobility Medicine 2025 (2025Pdm3) will be hosted at the Hotel Petrarca in Euganean Thermae (Padua, Italy) from 25 to 29 March 2025. It further testifies by listing unique Sessions that it is possible to organize valid countermeasures to the inevitable tendencies towards hyperspecialization that the explosive increase in scientific progress brings with it. Furthermore, the European Journal of Translational Myology and Mobility Medicine (Ejtm3) will accept typescripts on results presented at the 2025Pdm3, together with the Special Section: New Trends in Musculoskeletal Imaging of the MDPI (Basel) Journal Diagnostics, because diagnosis is essential to prevent, manage and follow-up not only neuro-metabolic-muscular disorders, but the unavoidable physiologicical decay of performances in early and late aging.
