Article Citation - WoS: 1Citation - Scopus: 2Trends and Methods in Intensive Care Unit (ICU) Research Using Machine Learning: Latent Dirichlet Allocation (lDA)-Based Thematic Literature Review(BMC, 2025-07-29) Topaloglu, Duygu; Polat, OlcayIntroductionThe use of machine learning (ML) in intensive care units (ICUs) has led to a large yet fragmented body of literature. It is imperative to conduct a systematic analysis and synthesis of this research to identify methodological trends, clinical applications, and knowledge deficits.MethodsA systematic literature review was conducted in accordance with the PRISMA guidelines, encompassing 2,507 ICU-focused ML publications from 2019 to 2024. Latent Dirichlet Allocation (LDA), an unsupervised topic modeling approach, was used with n-gram and no-n-gram tokenization strategies. Bayesian optimization approaches were used to increase model coherence and diversity.ResultsThe analysis demonstrated a substantial degree of methodological variability, emphasizing the predominance of studies on infection surveillance and complication prediction. N-gram tokenization efficiently identified clinically specific topics, but no-n-gram techniques produced larger interpretative groups. Underexplored fields include emerging research areas like drug response prediction, pediatric-specific modeling, and surgical risk classification.ConclusionIn conclusion, the study highlights the significance of methodological transparency and tokenization strategies while offering a thorough topic overview and identifying methodological trends in the literature on ICU - ML. Future research should prioritize neglected areas such as pediatric care modeling and therapy response, utilizing advanced ML techniques and multimodal data integration to enhance the outcomes of ICU patients.Article Pressure Injuries Related to the Positioning of Surgical Patients in the Operating Room and Identification of Associated Risk Factors: A Cross-Sectional Study(Wiley, 2025-06-26) Usul, Osman; Dizer, BernaSurgery represents a significant risk factor for the development of pressure injuries. However, risk factors related to positioning-induced pressure-injuries in surgical operating rooms have not been adequately investigated. Therefore, this study aimed to determine the presence of pressure injuries and associated risk factors related to patient positioning in the operating room. This prospective, descriptive, and cross-sectional study was conducted between November 2023 and July 2024 in operating rooms of a university hospital, including surgeries from various surgical departments, with a cohort of 140 patients determined using a G*Power analysis. Data collection tools included the 'Individual Characteristics Form', 'Risk Assessment Scale for Pressure Injuries Related to Surgical Positioning' and 'Postoperative Patient Evaluation Form', with data collected pre, intra and postoperatively. We found that 25.7% of patients developed Stage I pressure injuries post-surgery, with the supine position being the most prevalent risk factor (p = 0.023). Patients with diabetes, higher body mass index, advanced age, longer surgeries and certain anaesthesia types had significantly increased risks (p < 0.05). Furthermore, 17.9% of patients were classified as high-risk. These findings underscore the need for nurses to monitor high-risk patients closely, adjust positioning as needed and develop tailored care plans to mitigate risk.Article Citation - WoS: 1Citation - Scopus: 1Functional capacity, physical activity, and arterial stiffness in patients with systemic sclerosis(Springer London Ltd, 2024-04-04) Tanriverdi, Aylin; Ozcan Kahraman, Buse; Sezgin, Nazenin Hande; Erez, Yesim; Acar, Serap; Birlik, Ahmet Merih; Ozpelit, EbruObjectives Systemic sclerosis (SSc) is a complex immune-mediated connective tissue disease, involving skin manifestations, vascular features, and organ-based complications that may affect functional capacity and physical activity. Functional capacity and physical activity are associated with arterial stiffness; however, this relationship has not been evaluated in patients with SSc. Therefore, the objective of this study was to investigate the association of functional capacity and physical activity with arterial stiffness in patients with SSc. Methods Sixty-five patients with SSc were enrolled in this cross-sectional study. Arterial stiffness was evaluated with carotid-femoral pulse wave velocity (cf-PWV). Functional capacity and physical activity were assessed with a six-min walk test (6MWT) and International Physical Activity Questionnaire-Short Form (IPAQ-SF), respectively. Results All participants were women, and the mean age was 54.91 +/- 11.18 years. 6MWT distance and IPAQ-SF were inversely associated with cf-PWV in crude analysis (p < 0.05). The relationship between 6MWT distance and cf-PWV was maintained in the fully adjusted model (beta = - 0.007, 95% CI, - 0.013 to 0.000). Similarly, the association between IPAQ-SF and cf-PWV remained significant in the fully adjusted model (beta = - 0.001, 95% CI, - 0.002 to - 0.001). Conclusion The present study indicates that functional capacity and self-reported physical activity are independently associated with arterial stiffness in patients with SSc. Exercise interventions targeted to increase functional capacity and physical activity may help to regulate arterial stiffness in patients with SSc.Article Identification of the sociodemographic and clinical characteristics of the patients who have undergone transcranial magnetic stimulation in a psychiatry clinic: A retrospective descriptive design(Wiley, 2021-05-05) Tasdemir Yigitoglu, Gulay; Cunkus, Nesrin; Ozgun Ozturk, Fatma; Saricay, KiymetPurpose The aim of this study, which is the first in this field in Turkey, is to determine the sociodemographic and clinical characteristics of patients who have undergone transcranial magnetic stimulation (TMS) in a psychiatry clinic. Design and Methods This study has a retrospective descriptive design. Data of 513 psychiatric patients who have undergone TMS between 2015 and 2018 in a university hospital were reviewed. Findings Significant differences were found between psychiatric diagnoses of the patients, based on their sex, marital status, and the number of courses of treatment with TMS (p < 0.05). Practical Implications It was suggested that nurses who would practice this procedure were required to be educated for TMS and nursing care to provide well and effective care.
