The aim of this retrospective observational study is to investigate and compare the real-world effectiveness and safety of upadacitinib when used as first-line exposure versus rescue exposure in patients with acute severe ulcerative colitis (ASUC). The key questions to be addressed are: In patients with ASUC, does upadacitinib administered as first-line induction exposure result in higher rates of colectomy-free survival, clinical remission, and endoscopic healing compared with its use as rescue exposure following failure of conventional or biologic therapies? What are the differences in the incidence, type, and severity of adverse events between these two real-world treatment exposure patterns? The researchers will conduct a retrospective analysis of medical records and electronic health data from patients diagnosed with ASUC who received upadacitinib either as part of routine first-line clinical care or routine rescue clinical care. All treatment decisions were made by treating clinicians per standard of care; the investigator did not assign or modify any therapeutic interventions. Data will be collected during a defined follow-up period to compare the real-world effectiveness and safety profiles of the two treatment exposure strategies.

This is a randomized controlled trial comparing the effects of peer education and traditional education on increasing knowledge and awareness of secondhand and thirdhand tobacco smoke exposure among geriatric care program students. Tobacco use and passive smoking are serious public health problems that cause millions of deaths each year and are highly prevalent among university students. Not only smoke dispersed in the air (secondhand smoke), but also toxic residues that accumulate on surfaces and can be absorbed through the skin and ingestion (thirdhand smoke) carry carcinogenic risks. It is a professional obligation for these students, who are the health professionals of the future, to protect the vulnerable elderly population they will serve from this exposure (especially residues carried on clothing/hair). It is also aimed to protect their own health against the risk of smoking triggered by occupational stress. Traditional education that only imparts information may be insufficient in changing behavior. Peer education based on Social Learning Theory offers a sincere and effective alternative that encounters less resistance among young people. While existing experimental studies in the literature generally focus on "active smoking and motivation to quit," this study fills an important gap by focusing on passive and third-hand exposure. If successful, this peer education model could be implemented as a standardized educational module at the national level in university campuses. Research hypotheses: H1: Students who receive peer education have higher levels of knowledge about secondhand smoke than students who receive traditional education. H2: Students who receive peer education have higher levels of awareness about thirdhand smoke than students who receive traditional education. H3: There is a difference between the pre- and post-intervention and between the experimental and control groups in terms of students' average scores for their awareness level of secondhand smoke. H4: There is a difference between the pre- and post-intervention and between the experimental and control groups in terms of students' average scores for their knowledge level of thirdhand smoke.
