Article Assessment of the Nutritional Status of Syrian Refugee Women in the Lactation Period(Sage Publications Inc, 2026) Isik, Tulay; Garipagaoglu, MuazzezBackground: The Syrian civil war has caused large-scale displacement, with many Syrian refugee women migrating to T & uuml;rkiye. Lactation is a critical period requiring adequate nutrition for maternal and infant health. However, data on the nutritional status of lactating Syrian refugee women are limited. Aim: This study aimed to assess the nutritional status of lactating Syrian refugee women who migrated to T & uuml;rkiye due to the Syrian civil war. Methods: A cross-sectional study was conducted between October 5, 2017, and January 29, 2018, with 102 lactating Syrian refugee women with infants aged 0-6 months attending the Istanbul Al Farah Child and Family Support Center. Participants were selected using convenience sampling. Inclusion criteria were being a Syrian refugee woman in the lactation period, having an infant aged 0-6 months, and volunteering to participate in the study. Women with chronic illnesses or metabolic disorders were excluded. Data were collected through face-to-face interviews with the assistance of a translator, using a structured Turkish questionnaire covering demographic information, anthropometric measurements, and 3-day dietary records. Dietary intake was analyzed with the BEBIS9 program and compared to the T & uuml;rkiye Nutrition Guide recommendations. Although the dietary data were collected in 2017-2018, the analysis was conducted using the most up-to-date national guidelines to reflect current public health priorities. Results: Participants (n = 102) had an average age of 27.9 +/- 5.7 years, BMI of 27.3 +/- 4.6 kg/m(2), and monthly income of 1267 TL. Their daily energy intake was 1593.7 +/- 556.5 kcal/day. A large proportion of participants had inadequate intake of micronutrients, with the highest insufficiency observed for pyridoxine (88.2%), followed by vitamin A (81.4%), vitamin C (76.5%), thiamine (71.5%), riboflavin (63.7%), folic acid (81.4%), vitamin B12 (72.6%), iron (62.8%), and zinc (68.6%). Women with higher BMI in early lactation consumed more fat (p < 0.05). Significant associations were found between micronutrient intake and sociodemographic factors (p < 0.05). However, due to the small sample size and use of convenience sampling, the generalizability of the findings is limited. Future studies with larger and more representative samples are needed to confirm these results. Conclusion: Syrian refugee women in the lactation period showed inadequate intake of energy and essential micronutrients, likely due to poor socioeconomic and living conditions. Interventions such as culturally sensitive nutrition education, postpartum micronutrient supplementation, and improved access to migrant-friendly healthcare services are needed. Additionally, targeted policies and sustainable public health nutrition programs-such as food voucher schemes, fortified food distribution, and maternal support groups-should be developed in collaboration with health institutions and NGOs to improve maternal and infant health outcomes in this vulnerable population.Article Federal Reserve Interest Rates, Investment Behavior, and Arbitrage in Exchange Traded-Funds(Conscientia Beam, 2026) Sobati, Pegah; Koy, Ayben; Colak, Andac BaturThis study investigates the influence of U.S. Federal Reserve interest rate policy on investor behavior, liquidity, and arbitrage efficiency in 29 iShares exchange-traded funds (ETFs) spanning large-, mid-, and small-cap benchmarks from 2013 to 2024. Using weekly data and econometric techniques combining time-series and panel approaches, the analysis incorporates key macroeconomic indicators, interest rates, the U.S. dollar index, economic activity measures, and market volatility to assess their combined effect on ETF market dynamics. Findings show that interest rate shifts significantly influence asset allocation, sector preferences, and risk tolerance, with higher rates often strengthening the dollar and increasing the appeal of fixed-income assets. Active trading is associated with narrower bid-ask spreads through enhanced liquidity, while passive investment widens spreads. ETF volatility is positively related to spreads, reflecting increased uncertainty and transaction costs in turbulent markets. The results provide empirical evidence on the behavioral channels linking monetary policy, market conditions, and trading efficiency, offering implications for policymakers, asset managers, and market participants. The major contribution of the study is to the empirical finance literature by integrating time-series and panel econometric methods to quantify the joint effects of interest rate policy, macroeconomic indicators, and investor sentiment on ETF market microstructure. Findings offer statistically robust insights into liquidity formation, volatility transmission, and arbitrage efficiency in diversified ETF markets.Article The Influence of Leisure Screen Time on Sleep Patterns and Feeding Behaviors in Primary School Children(Routledge Journals, Taylor & Francis Ltd, 2026) Aydoner Bektas, Selen; Bumin, GoncaThe increasing use of screen-based devices in children's daily lives has raised concerns about their effects on health behaviors such as sleep and feeding. This study investigated the relationship between leisure screen time and sleep and feeding problems in primary school children. A cross-sectional survey was conducted with 322 children aged 7-10 years and their parents. Parents completed questionnaires measuring children's daily leisure screen time, sleep patterns, and feeding behaviors. Results showed that weekend leisure screen time (M = 149.4 minutes/day) was higher than weekdays. Significant positive correlations were found between leisure screen time and both total feeding problem scores (weekdays: r = 0.22; weekends: r = 0.25, p < .01) and sleep disturbances (weekdays: r = 0.29; weekends: r = 0.32, p < .01). The most affected areas were selective eating and sleep initiation/maintenance. Regression analysis revealed that weekend leisure screen time significantly predicted feeding problems (beta = 0.22, p = .001) and sleep disturbances (beta = 0.27, p < .001), explaining 8% and 12% of the variance, respectively. The findings indicate the importance of managing children's screen time - particularly on weekends - to support healthier sleep and eating patterns and guide family-based interventions.Article Positioning School Readiness as Ecological Fit: The School Readiness Ecological Approach (SERA) for Occupational Therapy and Education(Routledge Journals, Taylor & Francis Ltd, 2026) Aydoner Bektas, SelenTraditional perspectives on school readiness have emphasized child-level competencies such as cognitive, language, and behavioral skills. While important, the narrow focus overlooks the ecological systems - families, teachers, and communities - that shape children's adaptation to school. The participation-oriented perspective of occupational therapy has also been largely absent from the discourse. The School Readiness Ecological Approach (SERA) reframes school readiness as a matter of ecological fit rather than merely a set of children's skills. Based on Bronfenbrenner's ecological systems theory and the Person - Environment - Occupation model, SERA conceptualizes readiness as the outcome of dynamic exchanges between children, families, educators, schools, and policy environments. SERA addresses key gaps by: (1) shifting focus from isolated child attributes to participation in real-life contexts; (2) integrating occupational therapy's holistic perspective into readiness; and (3) providing a multi-level framework to guide research, practice, and policy. SERA emphasizes four domains - child, family, educational environment, and community - as interconnected contributors to school readiness trajectories. As a conceptual bridge across education, health, and social systems, SERA will broaden theoretical scope, foster interdisciplinary collaboration, and promote inclusive, and sustainable strategies. Reconceptualizing school readiness as ecological fit will help move beyond deficit-based views and support more equitable and effective school transitions.Article Metformin Attenuates PTZ-Induced Seizures and Cognitive Impairment and Is Associated with Altered NOS/NO Signaling: Combined in Vivo and in Silico Evidence(Taylor & Francis Ltd, 2026) Ciltas, Arzuhan Cetindag; Sahin, Bilal; Hacisuleyman, Levent; Çetindağ Çiltaş, ArzuhanBackground: Epilepsy remains a major neurological disorder with high rates of drug resistance and cognitive decline. Repurposing neuroprotective drugs offers a promising approach. Metformin, a widely used antidiabetic agent, has shown anticonvulsant effects, yet its impact on nitric oxide synthase (NOS) isoforms in distinct brain regions remains unclear. Methods: Adult male Wistar rats were allocated into control, pentylenetetrazole (PTZ), or metformin+PTZ groups. Metformin (200 mg/kg, i.p.) was administered for 7 days before induction of acute PTZ seizures (45 mg/kg, i.p.). Seizure severity and latency were assessed using Racine's scale, and cognition was evaluated by the passive avoidance test (PAT). Nitric oxide (NO) and the expression of its synthesizing enzymes, inducible (iNOS), neuronal (nNOS), and endothelial (eNOS), were quantified in the cortex and hippocampus via enzyme-linked immunosorbent assay (ELISA). In silico analyses included target prediction and molecular docking to assess metformin - NOS interactions. Results: Metformin significantly reduced seizure severity, prolonged latency to the first myoclonic jerk, and prevented PTZ-induced memory impairment (all p < 0.001). These behavioral effects were accompanied by reductions in cortical and hippocampal nNOS and iNOS expression, decreased cortical eNOS levels, and lower NO accumulation. TargetNet predicted NOS isoforms among potential metformin targets, and docking indicated moderate binding affinity (-5.2 to -5.9 kcal/mol). Conclusion: Metformin exerted seizure-suppressing and cognition-preserving effects in an acute PTZ model, associated with reductions in NOS isoform expression and NO levels, suggesting altered NOS/NO signaling and supporting its potential as an adjunctive candidate for mitigating seizure-related neuronal dysfunction.Article The Effect of Sportive Latin American Ballroom Dance on Foot and Ankle Posture(Amer Podiatric Med Assoc, 2025) Kayiskiran, Onurcan; Coskunsu, Dilber Karagozoglu; Isiklar, CagdasBackground: Correct use of the feet, step techniques, and positions constitute significant factors in the success of a dancer. Moreover, the type of dance has crucial effects on the posture of the foot and ankle. Therefore, the primary aim of our study was to determine whether there was a relationship between dancesport, dance experience (years), shoe-wearing time (hours), and shoe heel height (centimeters) in dance athletes performing Sportive Latin American Ballroom (SLAB) dance. Second, we aimed to compare the foot posture of SLAB dancers and nondancers with similar demographic characteristics. Methods: Twenty-six professional SLAB dancers and 26 nondancers who had similar demographic characteristics and did not use high-heeled shoes volunteered to take part in this study. Foot posture (using the Foot Posture Index [FPI]), foot pronation (using the navicular drop test [NDT]), tibiocalcaneal angle, hallux valgus angle (HVA) (using a goniometer), and ankle dorsiflexion range of motion (ROM) (using the weightbearing lunge test) were evaluated. Results: There was a positive moderate correlation between FPI score and shoe-wearing time on the dominant (P = .041; r = 0.40) and nondominant (P = .026; r = 0.43) sides. A positive very good correlation was found between shoe heel height and HVA (P < .001; r = 0.75). A negative good correlation was observed between years of dancing and nondominant ankle dorsiflexion ROM (P = .027; r =-0.43). When dancers and nondancers were compared, a statistically significant difference was found between FPI and NDT scores (P < .001). The FPI and NDT scores, tibiocalcaneal angle, HVA, and ankle dorsiflexion ROM were significantly greater in the dancer group compared with the nondancer group (P < .001) in all measurements of the dominant and nondominant sides. Conclusions: Revealing the relationship between dance experience and shoe-wearing time and the difference between the foot posture and deformities of athletes who perform SLAB dance and those of nondancers constitutes a pivotal endeavor that will increase awareness and knowledge among dancers and clinicians. (J Am Podiatr Med Assoc 115(6), 2025; doi:10.7547/24-030)Article Examination of the Relationship Between Mothers' Self-Confidence and Maternal Attachment in the Postpartum Period(Springer Publishing Co, 2025) Kilic, Melek; Yilmaz, Tulay; Kaya, Husniye Dinc; Gunaydin, Sevil; Dinç Kaya, HüsniyeOBJECTIVE: The relationship between self-confidence and maternal attachment during the postpartum period is critical to both the infant's healthy development and the mother's psychosocial adjustment. This study aimed to evaluate the association between mothers' self-confidence levels and maternal attachment during the postpartum period. METHOD: The study employed a descriptive and correlational design. A purposive sampling method was used in the study, and 147 mothers who were between 1 and 4 months postpartum, over the age of 18 years, able to communicate in Turkish and competent to fill out an online survey were included in the study. The data collection tools included the Descriptive Information Form, the Karitane Parenting Confidence Scale (KPCS), and the Maternal Attachment Inventory (MAI). The collected data were processed and analyzed using the Statistical Package for the Social Sciences for Windows, version 24.0. RESULTS: The participants' mean total KPCS score was 35.95 +/- 4.39, and the mean MAI score was 92.71 +/- 5.34. No statistically significant association was found between maternal attachment and parental confidence levels (p > .05). Additionally, no significant differences were observed between participants' sociodemographic characteristics and their scale scores (p > .05). CONCLUSIONS: The findings suggest that maternal confidence and attachment, although both essential components of postpartum adjustment, function as independent constructs influenced by different psychological and contextual mechanisms. Understanding these dimensions separately may provide insights for developing targeted interventions to support mothers in the early postpartum period.Article Development and Psychometric Properties of the Self-Efficacy Scale for Symptom Management and Self-Care in Patients with Cardiac Surgery(Springer Publishing Co, 2025) Aksut, Rabia Saglam; Capik, Canturk; Elmas, Tugce BozkurtBackground and Purpose: Evaluating self-efficacy for symptom management and self-care is crucial for ensuring follow-up care after cardiac surgery. As there is not yet a validated measurement tool for this evaluation, the aim of this study was to develop the Self-Efficacy Scale for Symptom Management and Self-Care (SESMSC: Cardiac Surgery) in patients with cardiac surgery and to examine its psychometric properties. Methods: The Symptom Management Theory and Bandura's Self-Efficacy Theory were used as the theoretical background for scale development. A multiphase design was utilized. The initial development phase consisted of item generation and expert panel review. The second phase comprised a three-step validation process: (a) face and content analysis (CFA) for construct validity, and (c) Cronbach's alpha, test-retest, and item- total correlation analysis to assess internal consistency reliability. The sample (n = 401) was randomly divided into two subsamples for EFA and CFA (EFA group: n = 201; CFA group: n = 200). Results: EFA suggested a 20-item, two-factor structure with factor loadings of .342-.782. The two subscales of the scale were labeled symptom management self-efficacy and self-efficacy for ch's alpha, test-retest, and item-total correlation results demonstrated acceptable internal consistency reliability. Implications for Practice: The SESMSC: Cardiac Surgery may be a useful tool to evaluate self-efficacy for symptom management and self-care after cardiac surgery. Further evaluation in independent samples is needed to investigate its psychometric properties and usefulness in clinical practice.Article Evaluation of Pulmonary Function Test and Peripheral Muscle Strength in Smoking and Non-Smoking University Students(Georg Thieme Verlag KG, 2025) Tekeoglu Tosun, Anil; Yilmaz, Nergis; Uysal, Ogulcan; Aydin, Buket; Cambel, Ilayda; Karagozoglu Coskunsu, DilberObjective This study was conducted to compare pulmonary function and peripheral muscle strength in smoking and non-smoking university students. Materials and Methods Data were collected from 120 volunteer university students aged between 18 and 25 years, who were divided into two groups regardless of gender after their smoking status had been determined. Data were collected using a sociodemographic form, the Pulmonary Function Test (PFT), and the Five Times Sit-to-Stand and Six-Minute Walk tests to assess peripheral muscle strength. These tests were applied to both smoking and non-smoking groups. Results According to GLI 2012 reference values, female non-smokers exhibited significantly higher FEV1 and FEV1/FVC z-scores compared to female smokers (p<0.001 and p=0.008, respectively), whereas no significant differences were observed among males. No significant differences were found between smokers and non-smokers in peripheral muscle strength tests overall; however, gender-specific analyses revealed significant differences in some tests. Conclusion Significant differences were found in some pulmonary function tests between smoking and non-smoking university students, while no overall difference was observed in peripheral muscle strength. Gender-based subgroup analyses suggested varying effects on muscle strength and pulmonary function. Developing targeted smoking awareness programs for university students is important for public health.Article Citation - WoS: 2Effectiveness of Vibration in Reducing Pain and Improving Satisfaction During Subcutaneous Injections: A Randomized Crossover Clinical Trial(Taylor & Francis Ltd, 2025) Yildirim, Dilek; Kugu, EmreAimThe pain experienced during and after the injection may cause discomfort and lead individuals to develop a negative perception toward future injections. This study aimed to evaluate the impact of vibration stimulation on pain induced by subcutaneous injections and patient satisfaction.MethodsThis was a prospective, randomized, single-blind, crossover study design. Data were collected from 85 patients. Vibration and non-vibration subcutaneous anticoagulant injections were administered randomly by the same investigator following a standardized procedure. Pain and satisfaction were evaluated by a study-blind investigator using the Visual Analogue Scale immediately after the injection. Data were analyzed using descriptive statistics, the Student's t-test, paired sample test, and a generalized linear mixed model.ResultsA total of 175 injections were analyzed. It was found that the pain level of patients was lower when vibration was applied (4.06 +/- 1.68 vs. 5.32 +/- 2.19, p = 0.004). Additionally, patient satisfaction was higher when vibration was used (7.17 +/- 1.71vs. 5.97 +/- 2.46, p = 0.011).ConclusionThe results of this study demonstrated that vibration was effective in reducing the pain associated with subcutaneous anticoagulant injections and in increasing patient satisfaction. Vibration can be used as a method to alleviate pain from subcutaneous anticoagulant injections and enhance patient satisfaction. Clinically, this suggests that incorporating vibration during subcutaneous injections can be a simple, non-pharmacological strategy to improve patient comfort and adherence to therapy.
