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 1,2,4-Triazole Conjugates as HEGFR Inhibitors: Synthesis, Anticancer Evaluation, and in Silico Studies(Wiley-V C H Verlag GmbH, 2026) Bulbul, Bahadir; Kulabas, Necla; Gurboga, Merve; Ozakpinar, Ozlem Bingol; Cakmak, Ummuhan; Tuncay, Fulya Oz; Kucukguzel, IlkayA series of novel 1,2,4-triazole-acetamide derivatives was synthesized and evaluated for anticancer and hEGFR inhibitory activity. The compounds were obtained via multistep synthesis and characterized by spectroscopic methods. Cytotoxicity was tested against PC-3, MCF-7, A549, and K562 cell lines. Compounds <bold>18</bold>, <bold>19</bold>, and especially <bold>24</bold> showed notable antiproliferative effects, with compound <bold>24</bold> exhibiting higher selectivity and potency than gefitinib. It also induced apoptosis and inhibited migration in A549 and PC-3 cells, while selectively promoting invasion in PC-3, suggesting EMT-related behavior. In vitro kinase assays revealed compound <bold>20</bold> as the most potent hEGFR inhibitor (IC50 = 43.8 +/- 1.3 nM). Molecular docking and 200 ns molecular dynamics simulations confirmed its stable interaction with EGFR, particularly involving Cys797. These findings highlight compounds <bold>20</bold> and <bold>24</bold> as promising candidates for further development as EGFR-targeted anticancer agents.Article In Vivo Antioxidant and Anti-Inflammatory Effects of Myrtus Communis Against Ionizing Radiation-Induced Gastrointestinal Injury: Trod-Grog Study(Kare Publishing, 2025) Kilic, Melisa Bagci; Varan, Melike Pekyurek; Atasoy, Ozum; Ozyilmaz, Nagehan; Pazarbasi, Seren Ede; Ertas, Busra; Atasoy, Beste Melek; Ercan, FerihaOBJECTIVE: This study aimed to investigate the in vivo radioprotective effects of Myrtus communis (MC) on the gastrointestinal system. METHODS: A total of 30 female rats were divided into four groups: i) Control; ii) irradiation (IR) only; iii) MC-pretreated; and iv) MC-treated. The rats received oral MC extract (100 mg/kg/day) for 4 days before exposure to 10 Gy IR or continued until sacrifice. On the fourth day of IR exposure, the rats were sacrificed, and histopathological and biochemical analyses were performed on the ileum, pancreas, and liver tissues. RESULTS: Malondialdehyde and myeloperoxidase levels decreased in both MC-treated groups, while glutathione levels and Na+-K+-ATPase activity increased (p<0.01), with significant histopathological improvements compared to the IR-only group. CONCLUSION: The results of this study demonstrate that MC significantly decreases ionizing radiation-induced oxidative and inflammatory damage in the gastrointestinal systems of rats. Therefore, it may be regarded as a new candidate with radioprotective potential for future clinical application.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.

Materials and Methods: In this single-center crosssectional study, we included 100 kidney transplant recipients in a university hospital in a western city of Turkiye. The Translation and Cultural Adaptation Report from Professional Society for Health Economics and Outcomes Research was used for the transcultural adaptation of BAASIS to Turkish. We tested the validity of the BAASIS Turkish version by the level of evidence according to the American Educational Research Association guidelines: content validity, internal structure, and relations to other variables. We calculated item-total correlations of the BAASIS Turkish version to examine internal consistency reliability. Results: The content validity index score of BAASIS was calculated as 1.00, indicating agreement between the experts. Exploratory factor analysis evaluated the internal structure of BAASIS, and the coefficients for inter-item correlations ranged from 0.170 to 0.395. The Immunosuppressive Treatment Adherence Scale and the BAASIS nonadherent scores were significantly correlated (r = 0.673, P < .001). The coefficients for item-total correlation analyses ranged from 0.160 to 0.470. Conclusions: The BAASIS Turkish version has acceptable psychometric properties. The scale can be used in clinical practice and research projects in transplantation to assess immunosuppressive medication adherence.Article Emergency Department Nurses' Knowledge and Practices Related To Extravasation Injuries of Non-Cytotoxic Medications(Turkish Assoc Trauma Emergency Surgery, 2025) Kugu, Emre; Akyuz, NurayBACKGROUND: Extravasation of non-cytotoxic medications can lead to serious complications such as pain, tissue necrosis, limb loss, and even death. This descriptive cross-sectional study aims to assess the knowledge levels of emergency department (ED) nurses regarding extravasation incidents involving non-cytotoxic medications and to highlight the importance of effective management and prevention. METHODS: The study was conducted in the EDs of three hospitals in Istanbul, T & uuml;rkiye, between November 19, 2020 and December 31, 2020. A total of 100 ED nurses participated in the study. Inclusion criteria required nurses to be working full-time in the EDs during the study period and to provide written and verbal consent. The study utilized a survey to assess sociodemographic characteristics, knowledge of non-cytotoxic medications (e.g., epinephrine), symptoms of extravasation, prevention strategies, and intervention practices. RESULTS: The mean age of the nurses was 29.43 years, with 57% female and 73% holding a bachelor's degree. Among participants, 52% had 0-3 years of ED experience. Ninety-one percent reported not receiving education on extravasation after graduation, and 82% indicated no extravasation protocol was in place at their workplace. Knowledge about non-cytotoxic medications causing extravasation significantly increased with ED experience (p=0.035). Nurses in units with an extravasation protocol had significantly higher knowledge levels (p=0.007). Female nurses demonstrated better knowledge of extravasation symptoms than male nurses (p=0.012). Nurses with a bachelor's or higher degree had significantly better knowledge than others (p=0.015). The knowledge rate for the extravasation care protocol was 64%, with the most recognized protocol item being "immediately stop the infusion" (97%) and the least recognized being "aspirate the medication not to exceed 3-5 mL" (33%). Strong correlations were found between non-pharmacological factors and knowledge of non-cytotoxic medications (r=0.601; p<0.001), as well as between knowledge of extravasation care protocols and non-pharmacological factors (p<0.001). CONCLUSION: The study highlights the need for targeted education and the establishment of institutional protocols for managing and preventing extravasation in EDs. Nurses' knowledge significantly impacts their adherence to prevention and care protocols. To ensure patient safety, it is important to provide ongoing education and implement evidence-based intervention protocols for the management of extravasation in ED settings.Article 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, SahabettinThe 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.Article Citation - WoS: 2Citation - Scopus: 2Synthesis of Novel Thiazole/Thiadiazole Conjugates of Fluoroquinolones as Potent Antibacterial and Antimycobacterial Agents(John Wiley and Sons Inc, 2025) Poyraz Yılmaz, P.; Kulabaş, N.; Bozdeveci, A.; Vagolu, S.K.; Imran, M.; Tatar, E.; Küçükgüzel, İ.; Yilmaz, Pinar PoyrazTwenty azole-fluoroquinolone hybrids were designed and synthesized by conjugating thiazole and thiadiazole structures to ciprofloxacin and norfloxacin via a 2-oxoethyl bridge. The structures and purities of the synthesized compounds were proven by spectral techniques. The antimycobacterial effects of target compounds 21–40 were tested against Mycobacterium tuberculosis H37Rv strain. Among the 20 synthesized compounds, 12 exhibited minimal inhibition concentration (MIC) values in the range of 1.56–25 μg/mL. Among the molecules screened for antimycobacterial effects, the most effective was compound 35, a thiadiazole-ciprofloxacin hybrid. The cytotoxic effect of this molecule was found to be lower than the reference drugs, and it was also determined to be a more effective inhibitor than ciprofloxacin and norfloxacin in the DNA-gyrase supercoiling test. The antimicrobial effects of compounds 21–40 were screened by agar-well diffusion and microdilution tests against Gram-positive/negative bacteria, a fast-growing mycobacterium, and two yeast strains. While most of the compounds tested showed antibacterial effects, the most effective fluoroquinolone derivative appeared to be compound 31 with an MIC value of < 0.63 μg/mL against all Gram-negative bacteria tested. Azole-fluoroquinolone hybrids 21–40 did not show any activity against non-pathogenic Lactobacillus species and yeast-like fungi, indicating that they have selective antibacterial and antimycobacterial activity, particularly against Gram-negative bacteria. In silico molecular docking studies were conducted to uncover the interactions between lead compound 35 and the DNA gyrase proteins of M. tuberculosis and S. aureus. Additionally, a 100 ns molecular dynamics simulation was carried out to assess the stability of the complexes formed between compound 35 and both proteins. © 2025 The Author(s).
