    The Relationship Between Spiritual Well-Being, Resilience, and Adherence Among Patients Receiving Hemodialysis Treatment in Türkiye
    (Springer, 2026) Bulbul, Elif; Sukut, Ozge; Dikec, Gul
    This study examined the relationship between spiritual well-being, resilience, and adherence of hemodialysis patients and the factors affecting them. The data were collected from 182 hemodialysis patients receiving treatment in a dialysis center who met the inclusion criteria by purposive sampling method in Istanbul. The data were collected with the patient description questionnaire, which measures patient sociodemographic characteristics and characteristics related to the medical diagnosis, the Spiritual Well-Being Scale, the Brief Resilience Scale, and the End-Stage Renal Failure-Adherence Questionnaire. Gender, educational status, employment status, and mean age of patients were found to be correlated with psychological resilience. Marital status, employment status, cohabitants, and mean age of patients were found to be correlated with spiritual well-being. Gender, number of weekly dialysis sessions, and dialysis competencies were found to be correlated with hemodialysis patients' adherence to their treatment. Hemodialysis patients' adherence was positively correlated with both the faith subscale of spiritual well-being and psychological resilience. According to regression analysis, gender and resilience explained 12.8% of the total variance of adherence. This study determined that resilience is an essential factor in increasing the adherence of hemodialysis patients.

    Comprehensive Bibliometric Analysis of Characteristics, Patterns, and Causes of Retractions in Pediatric Literature
    (Springer, 2025) Abo-Elnour, Dina Essam; Helal, Mohamed Mohsen; Albalasy, Abdulrahman Ahmed; Abdul-Hafez, Hamza A.; Abdelkader, Ahmed; El-Sherbini, Eman Raafat; Amer, Samar A.
    This study aimed to systematically identify the key characteristics of retracted articles in pediatric literature and explore the patterns and reasons of pediatric retraction from 1995 to 2024. We searched PubMed and Retraction Watch databases to identify all retracted publications in the field of pediatrics. After the screening process, data were extracted into Excel. Statistical analysis was conducted using Jamovi and Excel. A correlation matrix was used for the important retraction-related factors. After screening, 590 unique retracted pediatric articles were included, with most of them, 572 (96.9%), having retraction notices available; 516 (87.5%) published as open access; 433 (73.4%) from Asia-mostly China; 348 (59%) retracted by the publisher; 301 (51.0%) published by Hindawi; 275 (46.6%) observational studies; and 221 (37.5%) retracted due to misconduct. Articles with four authors showed the highest retraction rate, and the retraction rate generally decreased as the number of authors increased. Most retractions occurred in 2023. The most common pediatric age group included in the retracted papers was children. The median H-index of authors of retracted papers was 8 for first authors and 10 for senior authors. The median time from submission to acceptance of retracted papers was 50 days and that from publication to retraction was 15 months. Additionally, time to retraction was positively correlated with the journal's impact factor (r = 0.106, p = 0.015) and the citation count (r = 0.213, p < 0.001) but showed no significant correlation with time to acceptance (r = - 0.019, p = 0.675). Conclusion: The increasing number of retracted pediatric papers reflects a growing concern with a complex pattern and various determinants. Researchers and publishers should adopt strong regulations and guidelines to improve the integrity of scientific research, especially pediatric research.

    Recognition of Clove (Eugenia Caryophyllata) Oil Adulteration by Monitoring Phenolic and Antioxidative Fingerprint Markers Utilizing Online HPLC Post Column and Spectrophotometric Assays With Chemometric Analysis
    (Springer, 2025) Ersoy, Seyda Karaman; Kaya, Elif Nilay; Celik, Saliha Esin; Senol, Onur; Apak, Resat; Karaman Ersoy, Şeyda
    This research aims to develop a reliable and versatile methodology for authenticating clove (Eugenia caryophyllata) oil (CLO). Key variables included total antioxidant capacity (TAC), total phenolic content (TPC), quantitative analyses and/or individual antioxidant capacity of fingerprint markers including eugenol (EUG) and tocopherol isomers (alpha-T, gamma-T, and delta-T) using reversed-phase liquid-chromatography (RP-HPLC) with post-column detection. A total of 28 commercial CLO samples (certified as 100% pure and other commercial samples), potential adulterants like vegetable oils (sunflower oil (SFO) and corn oil (CO)), and 14 synthetically adulterated CLO samples blended with varying proportions (ranging from 5 to 50%) of SFO and CO were analyzed. The EUG content and antioxidant capabilities of each marker were ascertained by online RP-HPLC analysis with post column detection utilizing CUPRAC (cupric reducing antioxidant capacity). EUG content in commercial CLO ranged from 1.46 to 98.06 mg g(-1), while TAC ranged between 18.54 and 748.46 mu mol g(-1) Trolox equivalents (TE), as determined by the online HPLC-CUPRAC method. Depending on the type and ratio of adulterating oils, a considerable decrease in the TAC values of virgin CLO was recorded. Classification of the commercial and synthetically adulterated CLOs (total of 42 samples) was performed using partial least square discrimination analysis (PLS-DA) and hierarchical cluster analysis (HCA). Adulteration levels above > 5% were successfully detected with 95% confidence. Thus, the proposed chemometric strategy combining selected chemical markers and TAC data demonstrated high potential for authenticating CLO. This technique provides a more focused investigation alternative for determining the authenticity and quality of commercial CLO.

    Unraveling the Persistent Renal Impact of Intrauterine Growth Restriction and Catch-Up Growth: Integrating Morphological Insights with Metabolomic Profiling
    (Springer, 2025) Esrefoglu, Mukaddes; Koktasoglu, Fatmanur; Bayindir, Nihan; Cimen, Fatma Bedia Karakaya; Kirmizikan, Seda; Hekimoglu, Emine Rumeysa; Selek, Sahabettin
    The study aimed to investigate the long-term effects of IUGR and consequent catch-up growth on metabolic health by using a comprehensive approach that included histopathological, immunohistochemical, biochemical, and metabolomics analyses. Sprague-Dawley pregnant rats either undergo bilateral uterine artery ligation or a sham surgery on the 19th day of gestation. The offspring reached catch-up growth, kidney samples were collected at postnatal weeks 2, 4, and 8 for analysis. IUGR rats exhibited a spectrum of changes including reduced glomeruli number, proliferating cell number, altered oxidative stress markers, various enzymes involved in Krebs cycle, mitochondrial dynamics, and energy metabolism. Examination of the 8-week-old cohort identified a broader spectrum of metabolic alterations, notably in the biosynthesis of phenylalanine, tyrosine, and tryptophan, phenylalanine, tyrosine, glyoxylate, dicarboxylate, pyruvate, alanine, aspartate, and glutamate metabolism, glycolysis/gluconeogenesis and citrate (TCA) cycle. Our metabolomics analysis provides insights into the potential disease susceptibility of individuals born with IUGR, including obesity, diabetes, hypertriglyceridemia, cardiovascular diseases, and mental retardation. These findings underscore the intricate interplay between intrauterine conditions and long-term metabolic health outcomes, highlighting the need for further investigation into preventive and therapeutic strategies to mitigate the risk of metabolic diseases in individuals with a history of IUGR.

    The Psychometric Properties of Body-Related Self-Conscious Emotion Measures for Turkish Adolescents: Esem and Cfa Approaches
    (Springer, 2025) Urfa, O.; Aşçı, F.H.
    The aim of this study was to investigate the psychometric properties of the “Body and Appearance Self-Conscious Emotions Scale (BASES)” and “Body and Fitness-Related Self-Conscious Emotions Scale (BSE-FIT)” for Turkish adolescents. Each scale consists of 16 items and four subscales (shame, guilt, authentic pride, and hubristic pride) and items are responded on 5-point Likert scale. The psychometric properties of BASES and BSE-FIT were tested on 332 girls and 264 boys, a total of 596 participants (Mage=13.88, SDage=1.92). Confirmatory factor analysis (CFA) and exploratory structural equation modelling (ESEM) with multi-group analysis (MGA) were used to test the 4-factor and 2-factor structures and measurement invariance. Cronbach’s alpha internal consistency coefficient and composite reliability (CR) were calculated for reliability. According to the model fit indices and factor loadings, the most appropriate model was the 4-factor CFA model for BASES and BSE-FIT. Cronbach’s alpha and CR coefficients were 0.79 and above in the 4-factor CFA structures of both scales. In addition, MGA demonstrated factor structures, factor loadings, intercepts, and measurement error variance of BASES and BSE-FIT were equivalent according to sex, school level, sport status, region, and body mass index. In conclusion, BASES and BSE-FIT are valid and reliable in Turkish adolescents, and both scales provided measurement invariance in adolescents with different demographic characteristics. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.

    Isolation of Rosmarinic Acid From Rosemary Extract Utilizing a Molecularly Imprinted Polymer
    (Springer, 2025) Ersoy, Ş.K.
    Molecularly imprinted polymers are polymeric materials engineered with specific templates capable of recognizing molecules selectively. Rosmarinic acid, an ester formed from caffeic acid and 3,4-dihydroxyphenyllactic acid and commonly occurring in plants, exhibits a broad spectrum of bioactive properties, including antioxidant, antiviral, analgesic, antibacterial, antimutagenic, antiallergic, anti-inflammatory, and neuroprotective effects. It is prominently present in rosemary (Rosmarinus officinalis) extracts, where it acts as the primary phenolic compound responsible for antioxidant activity. Advancements in the refining techniques for recovering and purifying rosmarinic acid from rosemary extracts have driven progress in molecularly imprinted solid-phase extraction methods. Remarkably, the molecularly imprinted solid-phase extraction approach utilizing the 1:4:16 caffeic acid-imprinted polymer exhibited outstanding selectivity for rosmarinic acid in authentic rosemary samples, achieving a purity level of 84% ± 2.96%. This research marks a significant advancement in the literature, being the first to demonstrate the effective purification of rosmarinic acid using caffeic acid-imprinted polymers. These findings underscore the efficacy of the MIPs in accurately capturing rosmarinic acid, illuminating their potential applications in pharmaceutical and analytical settings where precise molecule recognition and extraction methodologies are crucial. This innovative approach not only enhances the extraction process but also opens new avenues for the application of MIPs in various fields, including food chemistry and natural product research. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.

    Evaluation of the Effect of Sociodemographic Characteristics of Patients With Prostate Cancer on Their Sexual Experiences and Self-Efficacy Sexual Experiences and Self-Efficacy of Individuals With Prostate Cancer
    (Springer, 2023) Eroglu, Nermin; Ozkan, Ilknur
    The study was planned as a descriptive study to evaluate the effects of sociodemographic characteristics of prostate cancer patients on their sexual experiences and self-efficacy. The sample of the study consisted of 69 patients with prostate cancer who were followed up for treatment in the outpatient clinic of an oncology hospital between December 2020 and March 2021 and met the inclusion criteria of the stud. Research data were collected by using the Patient Information Form, Arizona Sexual Experiences Scale (ASEX)-Male, and Sexual Self-Efficacy Scale (SSES). The mean age of prostate cancer patients was 67.1 & PLUSMN; 11.74 years, 95.7% (n = 66) were married, 37.7% (n = 66) were university graduates, and 75.4% (n = 52) were unemployed. Patients' mean scores were 19.29 & PLUSMN; 7.66 on the total Sexual Self-Efficacy Scale and 22.08 & PLUSMN; 4.92 on the total Arizona Sexual Experiences Scale. In the study, it was determined that the sexual experiences and sexual self-efficacy of prostate cancer patients differed according to their education level, employment status, and duration of treatment. In the study, it was determined that patients with prostate cancer experienced sexual dysfunction and had low self-efficacy. In line with these results, our recommendations are for health professionals to evaluate the sexual functions of patients with prostate cancer and their sexual self-efficacy, which is an important determinant of sexual life, during the diagnosis, treatment, and care process. In addition, the sociodemographic characteristics of the patients should be considered when planning interventions that increase sexual self-efficacy in the management of sexual problems.

    (Springer, 2024) Umay, Ebru; Eyigor, Sibel; Demirag, Kubilay; Kaymak Karatas, Gulcin; Gundogdu, Ibrahim; Giray, Esra; Adiguzel, Emre
    There is no study about all aspects of oropharyngoesophageal (OPE) dysphagia from diagnosis to follow-up in a multidisciplinary manner in the world. In order to close this gap, we aimed to create a recommendation study that can be used in clinical practice, addressing all aspects of dysphagia in the ICU in detail with the opinion of experienced multidisciplinary experts. This recommendation paper was generated by a multidisciplinary team, using the seven-step process and a three-modified Delphi round via e-mail. Firstly, 15 open-ended questions were created, and then detailed recommendations including general principles, management, diagnosis, rehabilitation, and follow-up were created with the answers from these questions, Each recommendation item was voted on by the experts as overall consensus (strong recommendation), approaching consensus (weak recommendation), and divergent consensus (not recommended).In the first Delphi round, a questionnaire consisting of 413 items evaluated with a scale of 0-10 was prepared from the opinions and suggestions given to 15 open-ended questions. In the second Delphi round, 55.4% were accepted and revised suggestions were created. At the end of the third Delphi round, the revised suggestion form was approved again and the final proposals containing 133 items were created. This study includes comprehensive and detailed recommendations, including a broad perspective from diagnosis to treatment and follow-up, as detailed as possible, for management of dysphagia in patients with both oropharyngeal- and esophageal-dysphagia in ICU.

    (Springer, 2024) Urfa, Osman; Asci, F. Hulya
    The aim of this study was to investigate the atemporal mediating role of secondary irrational beliefs in the relationship between primary irrational beliefs and prosocial-antisocial behaviors in athletes. Ninety-two males (Mage=19.83 +/- 2.80) and 32 females (Mage=19.28 +/- 1.44), a total of 124 athletes (Mage=19.69 +/- 2.52) voluntarily participated in this study. Irrational Performance Belief Inventory-2 and Prosocial and Antisocial Behavior Scale were administered, and regression analysis was performed by using bootstrapping via PROCESS macro v4.2. Analysis indicated a significant atemporal direct effect of awfulizing belief on prosocial behaviors toward teammates and opponents. The direct effect of low frustration tolerance belief on prosocial behaviors toward opponents was also significant. Demandingness, awfulizing, and depreciation beliefs had atemporal direct effects on antisocial behaviors toward teammates. There were significant atemporal indirect effects of demandingness belief on prosocial behaviors toward teammates through awfulizing, prosocial behaviors toward opponents through low frustration tolerance, and antisocial behaviors toward teammates through low frustration tolerance and depreciation. In conclusion, there is atemporal mediating role of secondary irrational performance beliefs in the relationship between primary irrational performance beliefs and prosocial-antisocial behaviors.
