Article Nurses on the Frontline of Disaster: A Qualitative Metasynthesis of Post-Earthquake Care Experiences(Wiley, 2026) Kolac, Nurcan; Taylan, Secil; Eroglu, NerminBackground Earthquakes generate urgent and complex care needs, positioning nurses as key responders. Exploring their post-earthquake care experiences is vital for strengthening disaster preparedness and nursing practice.Aim This study aimed to synthesise qualitative evidence on nurses' experiences of providing care in the aftermath of earthquakes.Study Design This research was conducted through a systematic review and meta-synthesis of qualitative studies. The data were analysed using thematic analysis. The qualitative systematic review was conducted using Sandelowski and Barroso's four-step meta-synthesis methodology. This metasynthesis study, conducted in accordance with the PRISMA statement, is registered in PROSPERO. The following electronic databases and platforms were used for the literature review: MEDLINE, Academic Search Ultimate, CINAHL Complete, Complementary Index, Supplemental Index, Directory of Open Access Journals and WOS.Findings Based on 27 included studies, the research identified four main themes and 13 sub-themes related to nurses' post-earthquake care experiences. These themes were: (1) early post-earthquake nursing challenges, (2) conflict experiences, (3) valued experiences and methods of coping with challenges and (4) impact of rescue experiences.Conclusions This research highlighted nurses' post-earthquake care experiences, emphasising how they overcame challenges, redefined their profession and emerged stronger. It also identified the limitations and facilitators within the post-earthquake care environment, providing valuable insights for enhancing care settings during future earthquakes.Relevance to Clinical Practice This study identified limitations and facilitators in the post-earthquake care environment of clinical settings, providing valuable insights to improve care environments during future earthquakes.Article Verification Trials Can Create the Illusion of VO2max in Addition to Contributing to Its Confirmation(Wiley, 2026) Cabuk, Refik; Alp, Egemen; Murias, Juan Manuel; Karsten, BettinaThis study examined whether constant-workload verification trials performed at intensities below, at, and above the ramp-incremental peak power output (PPO) contribute to confirming maximal oxygen uptake (VO2max). Fifteen trained to well-trained male cyclists (VO2max: 63.6 +/- 5.6 mL & centerdot;kg(-1)& centerdot;min(-1)) completed maximal ramp testing followed by seven randomized verification trials (80%-110% PPO at 5% intervals) on separate days. Differences in VO2 responses were analyzed using linear mixed-effects models. Effect size was calculated using Hedges' g. The peak VO2 attained during the verification trials was expressed relative to the ramp-derived VO2max and classified as lower (< 95%), within normal variability (95%-105%), or higher (> 105%). The peak VO2 values at 80%, 105%, and 110% PPO were significantly lower than ramp-derived VO2max (p < 0.05), whereas no significant differences were observed at 85%, 90%, and 95% PPO. Effect sizes were small at 85%-95% PPO (Hedges' g = 0.29-0.32), medium at 100%-105% PPO (Hedges' g = 0.63-0.66), and large at 80% and 110% PPO (Hedges' g = 1.21-1.34). Of 105 verification trials, 81 were within +/- 5% of ramp VO2max, 22 were lower (mainly at 80% and 110% PPO), and two exceeded ramp VO2max (at 85% and 95% PPO). Although verification trials did not meaningfully contribute to the verification of VO2max, trials performed at 85%-95% PPO provided the best chances of confirming VO2max in trained individuals. Interpretation of verification trials relative to ramp-derived PPO is protocol dependent, which may limit generalizability across different ramp designs.Article Investigating the Personal and Professional Variables That Predict Discrimination Attitudes Among Nurses and Physicians(Wiley, 2025) Tekin, Suat; Seren, Arzu Kader Harmanci; Harmanci Seren, Arzu KaderIntroduction: Healthcare professionals are expected to provide holistic care to their patients without discrimination based on factors such as religion, language, age, gender, and race. Design: It is a cross-sectional descriptive study. Aim: The study aimed to examine the discriminatory attitudes of nurses and physicians working in hospitals in Sanliurfa and to define whether the personal and professional variables predict discriminatory attitudes among them. Methods: The STROBE reporting method, which is one of the EQUATOR guidelines, was followed. Data were collected from a total of 376 physicians and nurses through online platforms between March and June 2020 via the information form and the Discrimination Attitude Scale. Results: The discriminatory attitudes of the nurses and physicians participating in the study were above average. The total discriminatory attitudes scores of the participants varied according to sex, income levels, profession, hospital experience, and unit (p < 0.05). In addition, sex, profession and unit variables predicted the total discriminatory attitudes of nurses and physicians (p < 0.05). Conclusion: Although nurses' and physicians' discriminatory attitudes scores were generally higher, the highest mean score was in the subscale "discrimination against other nationalities." Sex, profession, and unit variables predicted the total discriminatory attitudes of nurses and physicians. Further quantitative and qualitative research is needed to understand the reasons for the highest discriminatory attitudes towards other nationalities among healthcare professionals, to overcome this issue. Clinical Relevance: Nursing or healthcare managers, as well as policymakers, may consider the predictive variables when staffing and training nurses and physicians working in similar regions and conditions.Conference Object Mitigating Bisphenol A-Induced Oxidative Stress in Serum: The Protective Effect of Probiotics(Wiley, 2025) Dede, P.; Pazarbasi, S. Ede; Sener, G.; Tunali-Akbay, T.Conference Object Structural and Biochemical Alterations in Zebrafish Embryos Exposed to Toothpastes with Different Detergent Contents(Wiley, 2025) Karagoz, A.; Beler, M.; Egilmezer, G.; Unal, I.; Cansiz, D.; Emekli, E.Conference Object Toothpastes with Different Detergent Contents Affect Morphogenesis and Redox System Parameters in Zebrafish Embryos(Wiley, 2024) Karagoz, A.; Beler, M.; Unal, I.; Cansiz, D.; Emekli-Alturfan, E.Article Why Do Nurses Transfer from Private Hospitals to Public Hospitals in Turkiye? A Descriptive Cross-Sectional Survey Study Considering Working Conditions, Compulsory Citizenship, Presenteeism, and Burnout(Wiley, 2025) Turan, Suzan; Seren, Arzu K. Harmanci; Harmanci Seren, Arzu K.This study investigates the reasons behind the transition of nurses from private hospitals to public hospitals in Turkiye, focusing on working conditions, compulsory citizenship behavior, presenteeism, and burnout. The study used a descriptive cross-sectional survey design. The sample consisted of 224 nurses who previously worked in private hospitals and were employed in public hospitals at the time of data collection. Researchers collected data via a questionnaire incorporating demographic questions and validated scales on compulsory citizenship behavior, presenteeism, and burnout. Parametric and nonparametric comparison tests were used to compare participants' experiences in private and public hospitals regarding working conditions. There were statistically significant differences between the groups (p < 0.05). Also, participant nurses' negative organizational behavior experiences scores (compulsory citizenship behavior, presenteeism, and work-related burnout) statistically significantly differed (p < 0.05), considering their scores based on private hospital and public hospital experiences. The study concluded that nurses worked longer and took less leave in private hospitals. Participant nurses also reported that they exhibited more compulsory citizenship presenteeism and experienced a higher rate of work-related burnout while working in private hospitals.Article Citation - WoS: 1Citation - Scopus: 1Dual-Phase Malicious User Detection Scheme for IM-OFDMA Systems Using IQ Imbalance(Wiley, 2025) Alaca, Ozgur; Althunibat, Saud; Riza Ekti, Ali; Yarkan, Serhan; Miller, Scott L.; Qaraqe, Khalid A.Physical-layer security techniques have contributed to the achievement of various security objectives in an efficient and lightweight manner. Thus, these techniques have been widely considered for limited-resource networks such as Internet of Things networks. Among the different security objectives, malicious user detection by exploiting physical-layer parameters has demonstrated efficient performance. In this work, malicious user detection in the recently proposed index modulation-based orthogonal frequency division multiple access (IM-OFDMA) is addressed. The proposed malicious user detection scheme exploits the hardware impairments, especially the in-phase and quadrature imbalance parameters, for both legitimate and malicious users to design a dual-phase efficient detection scheme. The proposed scheme accounts for the special characteristics of IM-OFDMA transmission that are different from other multiple-access techniques. The performance of the proposed scheme was evaluated considering detection probability and false alarm probability performance metrics. Moreover, closed-form expressions of these metrics were derived for both phases and were validated by Monte Carlo simulation results under different configurations of IM-OFDMA systems.Article The Effect of Compulsory Citizenship Behaviors on Subjective Vitality Among Nurses(Wiley, 2025) Elibol, Esengul; Yildiz, Bora; Seren, Arzu Kader HarmanciAim The study aims to assess the extent of compulsory citizenship behaviors (CCBs) and their impact on the nurses' subjective vitality based on self-determination theory. Background CCBs are harmful to both nurses and organizations. These behaviors mean employees are expected to perform additional tasks outside their job descriptions. Although CCBs are highlighted within the recent nursing literature, empirical evidence of their effects is lacking. Methods This is descriptive cross-sectional research. The study included 244 staff nurses using a convenience sampling method who worked in two hospitals in Istanbul. Data were collected via a survey consisting of a personal information form, the compulsory citizenship scale, and the subjective vitality scale. STROBE guidelines were followed when reporting the study. Descriptive statistical analyses, independent samples t-test, one-way ANOVA test, Pearson's correlation, and hierarchical simple linear regression analyses were used. Results The participants' mean scores for compulsory citizenship and subjective vitality were 3.34 out of 5 (SD = 1.05) and 4.15 out of 7 (SD = 1.36), respectively. Nurses' compulsory citizenship scores significantly differed according to their education level, income, and sector. Their subjective vitality scores statistically differed according to their income levels. Regression analysis revealed that CCBs were significant negative predictors of subjective vitality (beta = -0.22, p < 0.01). Conclusion By examining the CCBs and subjective vitality relationship, the current study extended the existing knowledge by drawing attention to the destructive and harmful effects of CCBs on positive psychological sources of nurses' subjective vitality. CCBs negatively predicted subjective vitality. Clinical Relevance Organizational factors such as CCBs, which leads to a lack of autonomy, affect nurses' well-being, thus affecting care quality and patient safety. As the International Council of Nurses mentioned, "Nurses cope with many physical, mental, emotional, and ethical challenges. It is essential that we address these challenges in a way that supports their overall health". In this regard, managers and policymakers in hospitals should develop preventive cautions for CCBs. However, in-service training activities should be carried out to increase awareness about the harmful effects of CCBs on nurses' psychological well-being.Article Citation - WoS: 4Citation - Scopus: 4Collagen Peptides and Saccharomyces Boulardii Cncm I-745 Attenuate Acetic Acid-Induced Colitis in Rats by Modulating Inflammation and Barrier Permeability(Wiley, 2025) Altinok, Oyku; Bas, Murat; Dolanbay, Elif Gelenli; Kolgazi, Meltem; Mert, Tugay; Uslu, Unal; Gelenli Dolanbay, ElifUlcerative colitis (UC) is an inflammatory bowel disease characterized by recurrent episodes of inflammation and tissue damage, with limited treatment options. This study aimed to investigate the effects of collagen peptides and Saccharomyces boulardii on acetic acid (AA)-induced colitis. Thirty-six male Sprague-Dawley rats were randomly divided into the following four groups: normal control (NC), colitis control (CC), collagen peptide (CP; 0.6 g/kg/day), and S. boulardii (SB; 250 mg/day). Colitis was induced by an intrarectal administration of AA in all groups except NC, and treatments were administered daily for 7 days. The therapeutic effects were evaluated by assessing the disease activity index (DAI), colon mass index, macroscopic and microscopic tissue damage, histopathological changes, zonula occludens (ZO)-1 protein expression, and myeloperoxidase (MPO) activity. The results showed that CP and SB treatments substantially alleviated DAI scores (p < 0.05) and reduced the colon mass index. Colon macroscopic and microscopic damages improved compared to the CC group (p < 0.01). Histologically, both treatments reduced inflammatory cell infiltration, crypt damage, and ulceration, with CP showing a slightly more pronounced effect. Immunohistochemical analysis revealed significant restoration of ZO-1 protein expression in the treated groups, indicating improvement in intestinal barrier integrity (p < 0.01). Furthermore, MPO activity was reduced in both CP and SB groups, significantly in the SB group (p < 0.01). These findings are consistent with previous studies that highlight the anti-inflammatory and barrier-enhancing effects of collagen peptides and probiotics in UC models.
