    The analysis of immunosuppressant therapy adherence, depression, anxiety, and stress in kidney transplant recipients in the post-transplantation period
    (Elsevier, 2022) Uyar, Betul
    Aim: Our study aimed to analyze the immunosuppressant therapy adherence, anxiety, stress, and depression in kidney transplant recipients in the post-transplantation period. Method: This study was conducted as descriptive and cross-sectional research with the participation of 260 re-cipients who underwent kidney transplantation and were already discharged from the hospital (n = 260). In the data collection process, we used the Personal Information Form, the Immunosuppressant Therapy Adherence Scale (ITAS), and the Depression Anxiety Stress Scale (DASS)-21. The One-Way Analysis of Variance (ANOVA), Chi-Squared test, post hoc and Pearson Correlation analysis methods were used in data analysis. Findings: In our study all participant kidney transplant recipients, 45.4% were age 46-64 years and 81.5% were men. As the recipients' age levels increased, their immunosuppressant therapy adherence levels decreased (p < 0.05). Similarly, kidney recipients with at least 3 adverse events (infection, gastrointestinal problems, edema, blood disorders etc.) had a higher DASS-21 score and a lower ITAS score than those with low side effects. ITAS had a strong negative relationship with DASS-21 (p < 0.05). Recipients' depression, stress, and anxiety scores were, in general, above the medium level. Conclusion: Adherence to the immunosuppressive drug regimen after kidney transplantation and depression, anxiety and stress are in a bidirectional relationship. At the same time, the side effects of immunosuppressive drugs can trigger the development of depression, anxiety and stress. After kidney transplant, recipients are at risk for the development of depression, anxiety, and stress. We recommend early detection of this condition and taking preventive and symptom-reducing interventions.

    An evaluation of the efficacy and side effects of a single dose of ketamine in major depressive disorder
    (Oxford Univ Press, 2024) Uyar, Betul; Gunes, Mehmet
    Aim This study aims to provide a comprehensive overview of the antidepressant and antisuicidal efficacy of ketamine in patients with unipolar depression, with a focus on the clinical evidence and safety profile.Material-Method In our study, the data of 120 major depressive disorder patients who received single-dose ketamine infusion therapy were evaluated retrospectively, with Montgomery-Asberg Depression Rating Scale (MADRS) applied by the clinician before treatment and at the 4th and 24th hours after treatment and side effects at 4 and 24 hours after treatment.Results There was a statistically significant difference between MADRS and MADRS-Suicide scores of all participants before the ketamine infusion (0th hour) and at the 4th and 24th hours after the ketamine infusion. Also, male and female, RAT(+) and RAT(-), and SA(+) and SA(-) participants have statistically significant differences on all three times for both MADRS and MADRS-S scores.Conclusion The findings of this study are in line with those from previous research that demonstrated the rapid and robust antidepressant effects of ketamine, even in individuals with severe, treatment-resistant depression. Moreover, the observed reduction in suicidal ideation is particularly noteworthy, given the critical need for interventions that can provide rapid relief in acute suicidal crises. Key message What is already known on this topic - Ketamine is known for its rapid antidepressant and antisuicidal effects in treatment-resistant major depressive disorder, demonstrating significant symptom relief within hours of administration. What this study adds - This study provides additional evidence supporting ketamine's rapid efficacy in reducing depressive symptoms and suicidal ideation, highlighting statistically significant improvements observed at 4 and 24 hours post-treatment. How this study might affect research, practice, or policy - The findings may encourage broader clinical adoption of ketamine for acute depressive episodes and suicidality, emphasizing the need for controlled medical settings to manage potential side effects, and could influence future research on optimizing dosing protocols and long-term safety.Conclusion The findings of this study are in line with those from previous research that demonstrated the rapid and robust antidepressant effects of ketamine, even in individuals with severe, treatment-resistant depression.
