    The Relationship Between Nurses Anxiety and Attitudes Towards Artificial Intelligence and Examination of Influencing Factors
    (BMC, 2026) Nirgiz, Cansu; Sari, Merve Kiymac; Cayli, Nazan
    Aim to explore the relationships between nurses'anxiety and attitudes toward artificial intelligence (AI) and the factors associated with them. Background Although AI technologies are increasingly integrated into healthcare, research exploring nurses ' psychological readiness and emotional responses to AI remains limited. Existing studies have primarily focused on nursing students or general healthcare professionals, leaving a gap in understanding how practicing nurses perceive and emotionally adapt to AI within real clinical environments-particularly in T & uuml;rkiye, where digital transformation in healthcare is accelerating. Addressing this gap is essential, as nurses play a pivotal role in ensuring the safe and ethical implementation of AI-driven tools in patient care. Methods This descriptive and correlational study included 562 nurses from 14 branches of a private hospital chain across seven Turkish cities between November 2024 and January 2025.This sample was selected because it represents nurses actively engaged in clinical decision-making within healthcare systems that are rapidly adopting AI technologies. According to a power analysis performed in G*Power (rho = 0.25, alpha = 0.05, power = 0.95), the required sample size was 202 participants. Data were collected through an online questionnaire comprising a Descriptive Information Form, the AI Anxiety Scale, and the General Attitudes toward AI Scale. Descriptive statistics, independent samples t-tests, ANOVA (F), Tukey post hoc test, Pearson correlation, and multiple regression analyses were conducted. Ethical approval was obtained from the Fenerbah & ccedil;e University Ethics Committee, and informed consent was obtained digitally. Results Nurses reported moderate anxiety levels and generally positive attitudes toward AI. Male nurses showed an association with lower anxiety levels and higher positive attitude scores than female nurses. Single individuals and those with higher levels of education showed higher positive attitudes toward AI. Those with 0-3 years of experience in the profession were associated with lower anxiety and higher positive attitude scores. Nurses who used AI in practice, were knowledgeable about its use, or perceived it as reliable showed a relationship with lower anxiety and more positive attitudes. Regression analysis showed that each one-unit increase in the learning and AI configuration subscales of the AI Anxiety Scale was associated with a 0.740-and 0.716-point lower score in the total attitude score, respectively. Conclusion The findings suggest that lower levels of anxiety related to learning and AI configuration are associated with more positive attitudes toward AI. Addressing these specific anxiety domains may be related to the successful integration of AI technologies into clinical practice and could be linked to the digital transformation in healthcare.

    Early Detection of Lower Adherence to Long-Term E-Diary Recording: A Checkpoint to Target Early Educational Intervention in Seasonal Allergic Rhinitis
    (Wiley, 2026) Dramburg, S.; Hernandez Toro, C. J.; Grittner, U.; Tripodi, S.; Arasi, S.; Acar Sahin, A.; Matricardi, P. M.
    Background: Digital symptom monitoring via e-Diary apps can support the diagnosis and management of chronic diseases with trigger-induced exacerbations such as pollen allergies. Attrition is a major challenge for continuous e-Diary usage with an unsupervised approach. Objective: To investigate adherence to e-Diary reporting, its early determinants and predictors in a blended care setting among pollen allergic patients with heterogeneous cultural backgrounds. Methods: The @IT.2020 observational multicenter study recruited patients with diagnosed seasonal allergic rhinitis from seven Southern European/Mediterranean countries. Baseline characteristics were investigated through questionnaires, skin prick tests and serum specific IgE measurements. The study doctors asked patients to record their allergy symptoms via e-Diary (AllergyMonitor, TPS) daily during the clinically relevant season of pollination and increased mould concentrations. Results: Among 815 patients (467 adults, 348 children), the average prescribed e-Diary recording period was 106 (SD 47.1) days, with an average completion rate of 75.2% (SD 21.2%). Children (>= 10 years) filled 73.8% (95% CI 68.1-79.4) of prescribed days without parental support. We identified a stable 'higher' and a more variable 'lower' adherence cluster. Adherence was weakly associated with disease severity, but not with age, gender, country, education or digital literacy. Short-term (first 3 weeks) adherence was strongly associated with long-term adherence (partial R-2 = 0.387, p < 0.001), with 87.6% of lower adherent patients remaining poorly adherent beyond 3 weeks. Conclusion: In a blended care setting, adherence to e-Diary compilation among pollen allergic patients is high, irrespective of age and cultural background. Early identification of lower adherence is possible and might inform early interventions to improve patient adherence.

    Evaluation of Octenidine Dihydrochloride-Induced Cytotoxicity, Apoptosis, and Inflammatory Responses in Human Ocular Epithelial and Retinal Cells
    (MDPI, 2025) Ciftci, Ihsan Hakki; Deveci Ozkan, Asuman; Erman, Gulay; Kilbas, Imdat; Aydemir, Ozlem
    Background/Objectives: Octenidine dihydrochloride (OCT-D) is a broad-spectrum antiseptic with high chemical stability, low toxicity, and no reported microbial resistance, making it a strong candidate for use on mucosal surfaces. Despite increasing interest in its potential ophthalmic applications, limited data exist regarding its cellular effects on ocular tissues. This study aimed to investigate the cytotoxic, apoptotic, inflammatory, and transcriptional responses induced by OCT-D in human conjunctival (IOBA-NHC) and retinal pigment epithelial (ARPE-19) cells. Methods: Cells were exposed to varying concentrations of OCT-D, and viability was assessed using the WST-1 assay to determine IC50 and IC50/2 values. These concentrations were subsequently used in molecular assays. Pro-inflammatory cytokines (IL-6, IL-1 beta, TNF-alpha, IFN-gamma) were quantified by ELISA. Apoptotic activation was evaluated through caspase-3/7 activity assays. Gene expression analysis of apoptotic (Bax, Bcl-2), DNA damage-related (ATM, Rad51), and inflammatory markers was performed using RT-qPCR. Results: OCT-D induced a marked, dose-dependent reduction in cell viability in both cell lines, with ARPE-19 showing greater sensitivity. Caspase-3/7 activity increased significantly at IC50 and IC50/2, confirming intrinsic apoptotic activation. OCT-D markedly suppressed the release of key inflammatory cytokines and downregulated transcription of inflammatory genes. RT-qPCR revealed upregulation of pro-apoptotic and DNA damage-associated genes, demonstrating coordinated activation of apoptotic and genomic stress pathways. Conclusion: OCT-D triggers integrated cytotoxic, apoptotic, and immunomodulatory responses in conjunctival and retinal epithelial cells. While these findings provide important mechanistic insights into OCT-D's cellular effects, further studies using primary cells, advanced 3D ocular models, and disease-relevant systems are required to support its potential translational use in ophthalmology.

    Low Dose Ionising Radiation Elicits MPTP Comparable Alterations in Locomotor Function, Oxidative Balance and Mitochondrial Homeostasis in Zebrafish Embryos
    (Nature Portfolio, 2025) Cahide, Ezgi; Bayramov, Aydas; Beler, Merih; Cansiz, Derya; Unal, Ismail; Egilmezer, Gizem; Yalcinkaya, Sebnem Ercalik
    Prenatal exposure to environmental factors including low-dose ionising radiation and neurotoxins may disrupt the oxidant-antioxidant balance. Our aim was to assess the effects of exposure to low-dose ionising radiation (LDIR) and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), which is a neurotoxin used to model Parkinson's disease (PD), on developing zebrafish embryos, focusing on the oxidant-antioxidant system and markers of mitochondrial damage associated with PD. Zebrafish embryos were divided into four groups: control, LDIR, MPTP, and LDIR combined with MPTP (LDIR + MPTP). A dental x-ray unit (60 kVp, 7 mA) was used for the exposures. The 0.08 s LDIR exposure was measured as 0.065 mGy using optically stimulated dosimeters. At the end of 72 h after fertilization, locomotor activities, acetylcholine esterase (AChE) activity, oxidative stress and antioxidant status were assessed. Expressions of genes associated with in PD as markers of mitochondrial damage (pink1, parkin, dj1 and lrrk2) were determined by RT-PCR. Developmental toxicity was observed in all exposure groups as evidenced by pericardial edema, yolk sac edema and spinal curvature. LDIR exposure in zebrafish embryos affected oxidative and mitochondrial stress markers, as well as locomotor activity and AChE as a marker of cognitive function at levels comparable to the MPTP exposure. Our study is the first to determine the effects of LDIR from a dental x-ray unit on the response to MPTP, and we aim to further elucidate the mechanism of these changes observed particularly in the LDIR + MPTP group.

    In Vitro Investigation of the Effects of Octenidine Dihydrochloride on Nasal Septum Squamous Carcinoma Cells
    (MDPI, 2025) Ciftci, Ihsan Hakki; Ozkan, Asuman Deveci; Erman, Gulay; Kilbas, Elmas Pinar Kahraman; Koroglu, Mehmet; Kahraman Kilbas, Elmas Pinar; Deveci Ozkan, Asuman
    Background/Objectives: The aim of this study was to investigate the cytotoxic, genotoxic, apoptotic, and anti-inflammatory effects of the antiseptic agent octenidine dihydrochloride (OCT-D) on the RPMI-2650 cell line derived from human nasal mucosa in vitro. Methods: RPMI-2650 cells and Human Umbilical Cord Endothelial Cells (HUVECs) were treated with various concentrations of OCT-D (0.00625-0.4%) for 12 and 24 h. Cell viability was assessed using the WST-1 assay, while DNA damage was assessed using the comet and micronucleus (MN) assays. Apoptotic activity was determined using Annexin V flow cytometry and fluorescence microscopy. Intracellular reactive oxygen species (ROS) levels were measured, and inflammatory cytokines (IL-1 beta, IL-6, TNF-alpha, and IFN-gamma) were measured by Enzyme-Linked Immunosorbent Assay (ELISA). The mRNA expression of genes associated with apoptosis, oxidative stress, and inflammation was analyzed using RT-PCR. Results: OCT-D caused dose- and time-dependent cytotoxicity, and RPMI-2650 cells showed greater resistance compared to HUVECs. While a strong apoptotic response was observed in HUVECs, RPMI-2650 cells exhibited limited apoptosis. OCT-D was found to cause dose-dependent DNA damage and an increase in MN in both cell lines. OCT-D significantly reduced cytokine levels and ROS production in both cell types. RT-PCR results supported its anti-inflammatory and antioxidant effects at the molecular level. Conclusions: In conclusion, this study demonstrated that OCT-D exhibited minimal cytotoxic and apoptotic effects in RPMI-2650 cells, but affected vascular structure by inducing apoptosis in endothelial cells. These findings provide important evidence that OCT-D can be used as a potential adjunctive agent in nasal treatments, and these data need to be supported by preclinical and clinical studies.

    Beyond Age: Understanding How Mindful Eating and Food Label Reading Shape Generational Differences in Health Outcomes – A Cross-Sectional Study
    (BMC, 2025) Altinok, Oyku; Yalcin, Bahar; Deniz, Melike Seyma; Celikayar, Melike Nur; Sevdin, Sezen; Bingul, Bengi Cetiner; Garipagaoglu, Muazzez
    BackgroundThe increasing prevalence of obesity and diet-related chronic diseases poses a considerable threat to public health. Consequently, understanding generational differences in dietary behaviors has gained growing importance. This study aims to examine the direct and indirect effects of generational cohort on anthropometric indicators and self-rated diet quality (SRDQ), mediated through mindful eating and food label reading attitudes.MethodThis cross-sectional design study involved 2725 participants from Generations X (n = 786), Y (n = 933), and Z (n = 1006) living in Istanbul, T & uuml;rkiye. Participants' sociodemographic characteristics and anthropometric measurements, including body mass index (BMI), waist circumference (WC), and waist-hip ratio (WHR), were recorded. Data on SRDQ were collected, alongside responses to the Mindful Eating Questionnaire and the Food Label Reading Attitude Scale. Descriptive statistics, one-way analysis of variance, and chi-square tests were applied to the data. The direct and indirect effects of generation groups were analyzed using structural equation modeling.ResultsIncreasing mindful eating scores were associated with higher label reading attitude and SRDQ scores, while they were related to lower anthropometric risk indicators. Higher label reading attitudes showed an association with reduced WHR and increased SRDQ. Generation Z participants reported significantly lower scores for mindful eating, label reading attitude, anthropometric measures, and SRDQ than Generation X participants. Lower mindful eating scores were related to increased BMI among Generation Z, whereas lower label reading attitude scores were positively associated with WC and WHR. Furthermore, poor mindful eating and label reading attitudes and the combined effects of low mindful eating and label reading attitudes were linked to lower SRDQ.ConclusionPoor mindful eating and label reading attitudes in Generation Z may threaten long-term health sustainability and increase the risk of developing chronic diseases. Combining generation-specific public health strategies with interventions aimed at improving nutritional literacy and mindful eating habits from an early age could enhance individual and societal health outcomes.

    (BMC, 2025) Domanic, Kubra Yildiz; Baycan, Sukran; Yildiz Domanic, Kubra
    BackgroundGenerative Artificial Intelligence (AI) models, such as ChatGPT (GPT-4) and Gemini, offer potential benefits in educational settings, including dental education. These tools have shown promise in enhancing learning and assessment processes, particularly in dental prosthetic technology (DPT) and oral health (OH) programs.ObjectiveThis study aimed to evaluate the accuracy, reliability, and consistency of GPT-4 and Gemini AI models in answering examination questions in dental education. The study focused on multiple-choice questions (MCQs), true/false (T/F) questions, and short-answer questions (SAQs).MethodsAn exploratory study design was used with 30 questions (10 MCQs, 10 T/F, and 10 SAQs) covering key topics in DPT and OH education. ChatGPT and Gemini were tested with the same set of questions on two separate occasions to assess consistency. Responses were evaluated by two independent researchers using a predefined answer key. Data were analyzed using descriptive statistics, the Kappa coefficient for agreement, and the Chi-square test for categorical variables.ResultsChatGPT demonstrated high accuracy in MCQs (90%) and T/F questions (85%) but showed reduced performance in SAQs (60%). Gemini's accuracy ranged between 60% and 70%, with the highest accuracy in SAQs (70%). ChatGPT showed significant consistency across testing dates (Kappa = 0.754; p = 0.001), whereas Gemini's responses were less consistent (Kappa = 0.634; p = 0.001).ConclusionWhile both AI models offer valuable support in dental education, ChatGPT exhibited greater accuracy and consistency in structured assessments. The findings suggest that AI tools can enhance teaching and assessment methods if integrated thoughtfully, supporting personalized learning while maintaining academic integrity.

    (Frontiers Media S.A., 2025) Sirma, Gamze Cagla; Zengin Alpozgen, Ayse; Balikci, Aymen
    Background and objectives: This study investigated the effectiveness of the Homeostasis-Enrichment-Plasticity (HEP) Approach in preterm infants with increased developmental risk, compared to the Traditional Treatment (TT) intervention for physical and occupational therapy.<br /> Materials and methods: Twenty-nine preterm infants (adjusted age, 4-10 months) were randomly assigned to two groups: the HEP Approach group and the TT group. The Peabody Developmental Motor Scales-2 (PDMS-2), Test of Sensory Functions in Infants (TSFI), and Beck Anxiety Inventory (BAI) were administered pre-and post-intervention. The intervention was implemented weekly for 12 weeks.<br /> Results: The baseline characteristics of the infants were similar. At the end of the treatment, a significant time effect was observed in motor skills and sensory functions across both groups, with improvements in all PDMS-2 and TSFI subtests (p < 0.05). Significant time x group interactions showed greater improvements in the HEP Approach group compared to the TT group for Fine Motor Quotient: F = 10.818, p = 0.003; Gross Motor Quotient: F = 5.691, p = 0.024; and Total Motor Quotient: F = 21.109, p < 0.001. For TSFI, the HEP Approach group showed greater improvements in Adaptive Motor Functions (F = 13.794, p = 0.001), Visual-Tactile Integration (F = 7.410, p = 0.011), and Total score (F = 11.316, p = 0.002). No significant time*group interactions were found for Reactivity to Tactile Deep Pressure, Ocular Motor Control, and Reactivity to Vestibular Stimulation (p > 0.05). Parental anxiety, measured by BAI, decreased significantly in both groups (F = 8.72, p = 0.006), but no significant time x group interaction was found (p > 0.05), indicating similar reductions in both groups. Conclusion: The HEP Approach demonstrated superior outcomes compared to the TT intervention in improving motor skills and sensory functions in preterm infants, while both interventions reduced caregiver anxiety.
