Background Ethical decision-making in nursing is crucial for care quality and patient safety. Nursing interns, being in a critical transition from students to professional nurses, have ethical decision-making abilities that are susceptible to environmental and individual factors. It is necessary to explore the latent profiles of ethical decision-making among interns and their influencing factors to provide targeted educational interventions. Aim To identify latent profiles of ethical decision-making in clinical nursing interns and analyze their influencing factors. Study Design A cross-sectional study design was adopted. Participants and Setting In August 2025, 640 nursing interns were recruited from four medical universities in China using convenience sampling. Data were collected via the Questionnaire Star platform, including a general information questionnaire, the Ethical Decision-Making Competence Scale (EDM-CS), the Perceived Social Support Scale (PSSS), and the Interpersonal Reactivity Index-C (IRI-C). Latent profile analysis was conducted based on the four dimensions of the EDM-CS, and multivariate logistic regression was used to analyze influencing factors. Ethical Considerations We obtained ethical approval from the First Affiliated Hospital of China Medical University (Approval number: [2024]710). Results Three latent profiles of ethical decision-making were identified: Ethical Decision-making Basic Type (35.47%, n = 227), Ethical Decision-making Intermediate Type (52.81%, n = 338), and Ethical Decision-making Integration Type (11.72%, n = 75). Multivariate logistic regression showed that male interns were less likely to belong to the Ethical Decision-making Intermediate Type (OR = 0.46, p =.008) and the Ethical Decision-making Integration Type (OR = 0.26, p =.017). A positive hospital teaching environment significantly promoted membership in both the Ethical Decision-making Intermediate Type (OR = 1.84, p =.009) and the Ethical Decision-making Integration Type (OR = 9.12, p

Introduction: Few studies are available on the prevalence and sleep-related factors of dementia with Lewy bodies (DLB) in Chinese older adults, aiming to explore the associations between sleep characteristics and DLB.Methods: A cross-sectional study with 7,528 individuals aged ≥65 years in 106 communities in Northern China was conducted from April 2019 to January 2020. Questionaries (including demographic characteristics, comorbidities, lifestyles, and sleep characteristics) were administered, and neuropsychological assessments and physical examination were conducted in phase I; screening for probable DLB was done in phase II. Logistic regressions were used to assess associations.Results: A total of 919 (12.2%, 919/7,528) participants had dementia, and 101 (1.3%, 101/7,528) participants were diagnosed with DLB. The prevalence of dementia and DLB were slightly higher or equal in women, increased with age, and roughly decreased with nighttime sleep duration. Of the 101 participants, all of them (100.0%) had cognitive impairment, 46 (44.54%) displayed fluctuating cognition, 72 (71.29%) of them showed visual hallucination, 22 (21.78%) individuals reported RBD, and 27.71% showed Parkinsonism. Sleeping for 8 h had combined diagnostic value for DLB (AUC = 0.783, 95%CI: 0.734–0.831, p < 0.001).Conclusions: The current prevalence of DLB is 1.3% in Northern China. Short or long nighttime sleep duration is independently associated with the occurrence of dementia and DLB.
