Article Comprehensive Proteomic and Metabolomic Analysis of Novel Substituted Fluoroquinolone Derivatives in Escherichia Coli Isolates(John Wiley and Sons Ltd, 2026) Nigiz Ş.; Kulabaş N.; Türe A.; Kablan S.; Koçak E.; Özkul C.; Küçükgüzel İ.; Koçak, Engin; Nigiz, Şeyma; Kablan, Sevilay Erdoğan; Özkul, Ceren; Kulabaş, Necla; Küçükgüzel, İlkay; Türe, AslıAntimicrobial resistance is one of the most important global problems, and new antibiotic requirements have been emerging as a key point in this issue. In the present work, we focused on the efficiency of two novel promising fluoroquinolone derivatives on resistant Escherichia coli isolates at the molecular level. Their mode of action and adaptation process were evaluated by using proteomics and metabolomics analysis. Proteomics analysis showed that two compounds have an effect mainly on the ribosomal process and energy metabolism. Moreover, we observed compounds that affect various important antimicrobial targets, such as ribosomal subunits, phosphotransacetylase, and chaperone proteins. In metabolomics analysis, we found that compounds altered bacterial metabolism directly. Pathway analysis showed that cofactor biosynthesis and energy metabolism were affected mainly by undertreated groups. Our experiments demonstrated that novel fluoroquinolone derivatives have promising results at the molecular level and results will contribute to further studies. © 2026 John Wiley & Sons Ltd.Article Telerehabilitation Transforms Recovery: Elevating Outcomes for Lower Limb Amputees(Wolters Kluwer Health, 2026) Ozturk, BasarBackground: Telerehabilitation provides a viable alternative for individuals facing barriers to in-person rehabilitation because of transportation issues and physical limitations. It enables remote monitoring and guidance, allowing patients to continue rehabilitation at home. Objective: This study aimed to assess the effectiveness of a telerehabilitation program in improving physical and psychological outcomes for lower limb amputees and to evaluate adherence to a home-based exercise program delivered via video. Study design: A randomized controlled trial. Methods: Sixty participants with lower limb amputations were randomized to an experimental group (telerehabilitation) or a control group (standard care). The intervention involved a 4-week supervised phase followed by a 4-week unsupervised phase. Primary outcomes were physical capacity, measured by the Six-Minute Walk Test (6MWT), and psychological status, assessed using the Hospital Anxiety and Depression Scale. Secondary outcomes included adherence rates and patient satisfaction. Results: The experimental group showed significant improvements in 6MWT distance and Hospital Anxiety and Depression Scale scores compared to the control group. The mean 6MWT distance increased by 20% from baseline to the end of the supervised phase (P < 0.01) and was maintained during the unsupervised phase. Anxiety and depression scores significantly decreased (P < 0.05). Adherence was higher during the supervised phase (85%) but dropped during the unsupervised phase (60%). Conclusions: Telerehabilitation significantly improved physical and psychological outcomes for lower limb amputees. High adherence during the supervised phase emphasizes the importance of clinician support, whereas strategies are needed to sustain long-term engagement during the unsupervised phase.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 The Relationship Between Spiritual Well-Being, Resilience, and Adherence Among Patients Receiving Hemodialysis Treatment in Türkiye(Springer, 2026) Bulbul, Elif; Sukut, Ozge; Dikec, GulThis 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.Article Advances and Strategies in Biosensor-Based Diagnostics for Parasitic Infections: A Comprehensive Scoping Review(Springer, 2026) Aminizadeh, Selva; Alizadeh, Gita; Alizadeh, Zahra; Khalilzadeh, Balal; Abidin, Zurina Zainal; Marzi, Mahdi; Rafiei-Sefiddashti, RahelehParasitic diseases are among the most widespread infections worldwide, causing millions of deaths and illnesses each year. So rapid and accurate diagnosis is essential, requiring highly sensitive and specific tests. Biosensors can provide significant advantages over traditional diagnostic methods because of their specificity, sensitivity, speed, simplicity, ease of use, repeatability, and capacity for early-stage disease detection. Recent advances in modern diagnostic tools for detecting parasitic infections use nanomaterials such as gold nanoparticles, carbon nanofibers, and carbon nanotubes. These developments have significantly lowered detection limits to the picogram and femtogram levels. This review will cover recent advancements in biosensor-based diagnostic techniques in parasitology.Article Montelukast Attenuates Abdominal Aortic Aneurysm in Rats: Anti-Inflammatory and Antioxidant Effects(Elsevier, 2026) Tekin, Gozde; Cevik, Ozge; Cetinel, Sule; Sener, Goksel; Kizilay, MehmetObjective: Oxidative stress and inflammation are widely recognized as central mechanisms in the pathogenesis of abdominal aortic aneurysm. This study sought to examine the potential protective properties of montelukast in a rat model of aortic aneurysm. Methods: Male Sprague-Dawley rats were randomly allocated into three experimental groups. Abdominal aortic aneurysm was induced using the calcium chloride (CaCl2) model, in which gauze soaked in 0.5 M CaCl2 was placed directly onto the adventitial surface of the infrarenal abdominal aorta for 15 minutes. After induction, the treatment group received daily intraperitoneal injections of montelukast (10 mg/kg) for 4 consecutive weeks. At the study end point, animals were euthanized, and infrarenal aortic tissues were harvested for biochemical and histological evaluations. Measured parameters included matrix metalloproteinase (MMP)-2 and MMP-9 expression, myeloperoxidase (MPO) activity, and 8-hydroxy-2 '-deoxyguanosine levels. Antioxidant capacity was assessed through superoxide dismutase (SOD) activity assays. Histopathological examinations were performed, and statistical analysis was conducted using GraphPad Prism v.5. Results: Exposure to CaCl2 triggered pronounced oxidative injury and inflammation, as evidenced by elevated 8-hydroxy-2 '-deoxyguanosine levels, increased MPO activity, reduced SOD activity, and upregulated MMP-2 and MMP-9 expression. Montelukast administration markedly attenuated these changes, normalizing oxidative and inflammatory markers while improving histopathological architecture. Conclusions: Montelukast effectively counteracted CaCl2-induced aortic damage. The protective effects of montelukast appear to be mediated through suppression of MMP activity, restoration of SOD levels, and reduction of MPO-driven oxidative injury. By mitigating both inflammatory and oxidative mechanisms, montelukast contributes to the preservation of aortic wall structure. Clinical Relevance: Abdominal aortic aneurysm remains a major vascular disorder without an effective pharmacological therapy to slow its progression. In this experimental study, montelukast, a leukotriene receptor antagonist widely used in asthma, attenuated abdominal aortic aneurysm formation in rats and was associated with increased superoxide dismutase activity, reduced myeloperoxidase levels, and suppressed matrix metalloproteinase activation. These combined antioxidant, anti-inflammatory, and matrix-stabilizing effects preserved aortic wall integrity. Given montelukast's established safety and clinical availability, these findings support its potential for future clinical investigation as a pharmacological approach to limit aneurysm progression.

However, caregivers of stroke patients often experience depression and anxiety, negatively impacting their mental health and reducing their quality of life. Psychoeducational interventions may be a solution to support the well-being of stroke caregivers. This study is performed to assess the overall effectiveness of individual psychoeducational interventions for caregivers of stroke patients. A thorough search of Scopus, PubMed, Web of Science, and Cochrane databases was performed for published studies in English up to June 2023. Clinical trials assessing the efficacy of psychoeducational interventions on quality of life, depression, or care burden among stroke caregivers compared to usual care were included. A total of 18 clinical trials, 16 randomized clinical trials (RCTs), and two non-RCTs, with a total of 2007 patients, were included. The study's pooled results revealed a significant increase in the quality of life in the group receiving psychoeducational interventions compared to the comparison group (SMD = 0.34, 95% CI 0.13-0.55, p value = 0.002), while no significant difference was found in terms of depression (SMD = - 0.05, 95% CI - 0.23 to 0.14, p value = 0.62) or caregiver burden (SMD = - 0.61, 95% CI - 1.65 to 0.44, p value = 0.25). Psychoeducation programs should be considered as a supportive intervention to improve quality of life in caregivers; however, their impact on depression and caregiver burden remains inconclusive. However, further studies with a larger sample size are needed to confirm the results.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 Measuring Shoulder Abduction Strength Using 2 Different Dynamometers: Comprehensive Intrarater and Interrater Reliability and Validity(Turkish Assoc Orthopaedics Traumatology, 2025) Atli, Ecenur; Topaloglu, Mahir; Hosbay, Zeynep; Ozdincler, Arzu RazakObjective: The purpose of this study is to investigate the intrarater and interrater reliability of handheld dynamometer (HHD) measurements in assessing isometric muscle strength of the shoulder abductors and to compare these results with those obtained using a fixed dynamometer (FD). Methods: The study involved 25 voluntary participants, all over the age of 18, asymptomatic (with no injuries in the upper extremity), and not engaged in overhead sports. The participants were evaluated twice by 2 different testers who were experienced in orthopedic rehabilitation, at 90 degrees of shoulder abduction in the scapular plane. On the first measurement day, Tester 1 performed measurements using both HHD and FD, while on the second measurement day, both testers used only the HHD. A 3-to 7-day interval separated the 2 measurement sessions. Paired-samples t-tests were used to evaluate the systematic bias between the testers. Spearman's rank correlation coefficient, intraclass correlation coefficient, standard error of measurement, and minimal detectable change were calculated. The statistical significance level was accepted as P < .05. Results: Data from 22 participants (15 women, 7 men; mean age: 23.00 +/- 3.19 years) were analyzed, as 3 individuals did not attend the final assessment. A strong correlation (r = 0.772) was found between Tester 1's HHD measurements and FD, while a similarly strong correlation (r = 0.748) was observed for Tester 2's HHD measurements. Excellent intrarater reliability (intraclass correlation coefficient [ICC]= 0.941) was found between Tester 1's measurements, and excellent interrater reliability (ICC= 0.889) was found between testers. Conclusion: Handheld dynamometer has demonstrated excellent interrater and intrarater reliability and high validity for assessing shoulder abductor muscle strength in research and clinical use. Since the muscle strength of testers using the HHD may influence the results, the FD may be a more appropriate option when the study population is stronger than the testers. Studies involving different clinical populations and testers with varying experience levels are needed to improve the relevance of the results. Level of Evidence: Level III, Diagnostic Study.
