The Role of Resilience in the Relationship Between Cyberbullying and Depression, Anxiety, and Stress in Adolescents
No full textPurpose:: This study investigates the mediating role of resilience in the relationship between cyberbullying and depression, anxiety, and stress. Method:: Data were collected from 591 adolescents (51.6% boys; Mage = 15.77 ± 1.12) using a socio-demographic questionnaire, the Cyberbullying Scale, the Brief Resilience Scale, and the Depression, Anxiety, and Stress Scale (DASS-21). Finding: Bivariate correlations revealed a moderate positive association between cyberbullying, anxiety, and stress. Structural equation modeling indicated that higher levels of cyberbullying were significantly associated with increased anxiety and stress but not with depression. Resilience was found to partially mediate the relationship between cyberbullying and stress but did not mediate the relationships between cyberbullying and either depression or anxiety. Conclusion:: These findings highlight that cyberbullying is a strong predictor of anxiety and stress, with resilience playing a key role in mitigating stress levels. Interventions focused on building resilience may offer an effective strategy for reducing stress among adolescents experiencing cyberbullying
Efficacy and safety of doxorubicin–ifosfamide versus gemcitabine–docetaxel as first-line therapy in advanced nonuterine leiomyosarcoma: A multicenter real-world study
No full textNonuterine leiomyosarcoma (NU-LMS) is a rare and biologically distinct subtype of soft tissue sarcoma (STS) with clinical behavior differing from that of uterine leiomyosarcoma. In advanced or metastatic STS, immunotherapy has demonstrated only modest activity, and chemotherapy remains the cornerstone of treatment. However, there is a persistent unmet need for more effective and better-tolerated options in this population. This multicenter, retrospective study included 150 patients with histologically confirmed metastatic NU-LMS who received first-line doxorubicin–ifosfamide (AI) or gemcitabine–docetaxel (GD) at 26 oncology centers in Turkey between 2010 and 2024. The primary endpoint was overall survival (OS). Survival was analyzed using Kaplan–Meier estimates and Cox proportional hazards models. Of 150 patients, 79 received AI and 71 received GD. Median OS for the entire cohort was 21.0 months. Median OS was 22.0 months with AI and 19.1 months with GD (p =.18), median progression-free survival was 7.3 versus 6.1 months (p =.66), and overall response rate was 25.3% versus 29.6% (p =.58), indicating no statistically significant differences in efficacy between the two regimens. Hematologic toxicities were less frequent with GD. AI and GD demonstrated comparable efficacy as first-line regimens for advanced or metastatic NU-LMS, with fewer hematologic toxicities observed for GD. Tumor location may have prognostic implications. These findings support individualized treatment selection and highlight the need for prospective studies in this rare and understudied sarcoma subtype, while the recent LMS-04 trial underscores the importance of future comparisons with doxorubicin–trabectedin to further refine first-line strategies in LMS

The Effect of Self-care Behaviors on the Psychological Well-being of Patients Undergoing Chemotherapy
No full textBackground: While self-care is known to influence well-being in chronic illnesses, its specific role during chemotherapy—particularly within unique cultural contexts like Turkey—remains underexplored. Purpose: This study examined the relationship between self-care behaviors and psychological well-being (PWB) in Turkish chemotherapy patients and assessed self-care's predictive power on PWB. Methods: A cross-sectional study was conducted with 403 chemotherapy patients from a university hospital using convenience sampling. Data was collected using the Self-care Adequacy and Needs Level Scale (SCANS-Chemo) and Psychological Well-being Scale. Results: Patients demonstrated moderate self-care levels (Mean = 80.69 ± 22.94) and PWB (Mean = 35.63 ± 12.84). A very strong positive correlation was found between self-care and PWB (r = 0.917, p < 0.001). Higher self-care scores significantly predicted better PWB (β = 0.58, p < 0.001), explaining 32% of variance. Key factors associated with better outcomes included higher education,male gender, and recent chemotherapy initiation. Conclusion: Self-care behaviors are a significant predictor of psychological well-being in chemotherapy patients.Healthcare professionals should develop culturally-tailored self-care interventions to enhance patients' psychological well-being during treatment. Implications for Nursing:Clinical practice should incorporate structured self-care assessments, personalized self-care training focusing on activity maintenance and sleep regulation, and regular monitoring of patients' self-care capacity throughout chemotherapy treatment</p

VAN İLİNDE SAANEN KEÇİSİ YETİŞTİRİCİLİĞİ YAPAN MEVCUT İKİ İŞLETMEDE BAZI HAYVAN BESLEME VE YETİŞTİRME UYGULAMALARI İLE İŞLETME SAHİPLERİNİN DEMOGRAFİK ÖZELLİKLERİNE İLİŞKİN DURUM TESPİTİ
No full textÖzet Bu araştırma, Van ilinde faaliyet gösteren iki Saanenkeçisi işletmesinin yetiştiricilik uygulamalarını, sosyoekonomik yapılarını veüretim performanslarını inceleyerek bölgesel düzeyde Saanen keçisiyetiştiriciliğinin mevcut durumunu değerlendirmeyi amaçlamaktadır. Çalışmakapsamında Muradiye ve Gevaş ilçelerinde yer alan iki işletmede saha gözlemlerive 63 soruluk anket formu aracılığıyla elde edilen veriler analiz edilmiştir.Sonuçlar, her iki işletmenin Saanen keçisini yüksek süt verimi nedeniyle tercihettiğini, ancak üretim kayıtlarının tutulmaması, rasyon dengesinin yeterincesağlanmaması ve sınırlı teknik destek gibi nedenlerle verim düzeylerininpotansiyelin altında kaldığını göstermiştir. Birinci işletmede daha büyük sürüölçeği ve karma yem kullanımı nedeniyle süt verimi nispeten yüksek bulunurken (500lt/yıl), ikinci işletmede bu değer 400 lt/yıl düzeyinde kalmıştır. Oğlakölümleri, doğum sonrası bakım ve barınak koşulları ile yakından ilişkilibulunmuş; ayrıca işletmelerin devlet desteklerini yetersiz gördükleribelirlenmiştir. Çalışma, Van ilinde Saanen keçisi yetiştiriciliğiningelişebilmesi için kayıt sistemlerinin güçlendirilmesi, yem üretim veplanlamasının desteklenmesi, teknik danışmanlık hizmetlerininyaygınlaştırılması ve pazarlama kanallarının etkinleştirilmesi gerektiğiniortaya koymaktadır. </p
