The aim of this prospective observational study is to evaluate the effect of endotracheal cuff pressure management on postoperative complications in patients undergoing surgery under general anesthesia. Specifically, patients whose endotracheal cuff pressure is maintained at an optimal level using a manometer will be compared with those whose cuff pressure is assessed using the conventional palpation method.
The primary question the study aims to answer is whether maintaining endotracheal cuff pressure at an optimal level with a manometer reduces the incidence of postoperative airway-related complications compared with the classical palpation technique.

This study aims to evaluate whether guided visualization meditation can reduce the surgical stress response in patients undergoing open-heart surgery. Surgical stress response includes changes in hormones, blood glucose, and anxiety levels that occur before and after major surgery. Guided visualization meditation is a non-invasive relaxation technique that uses calming audio instructions to help patients imagine peaceful scenes and reduce stress.
In this study, patients scheduled for cardiac surgery will be assigned to one of two groups: an intervention group that receives guided visualization meditation and a control group that receives standard care only. Patients in the intervention group will listen to an audio recording containing guided visualization and calming background music through headphones. Sessions will be provided twice on the day before surgery, twice on the day of surgery, and twice on the first postoperative day.
To evaluate the effects of the intervention, blood samples will be collected to measure cortisol, glucose, and insulin levels. Anxiety levels will be assessed using the State-Trait Anxiety Inventory (STAI-I and STAI-II), and pain will be measured using a visual pain scale. These measurements will be performed at three specific time points: one day before surgery, six hours after extubation, and one day post-surgery.
The goal of this research is to determine whether guided visualization meditation can help reduce stress-related physiological and psychological changes in patients undergoing cardiac surgery. If effective, this method may offer a simple, safe, and supportive strategy to improve recovery and overall patient well-being.

While social media offers opportunities for connection and self-expression, it also brings significant challenges, particularly social media addiction, characterized by excessive and uncontrolled use. Although not officially recognized as a diagnostic category, its inclusion among behavioral addictions reflects its growing impact on mental health. Social media addiction may lead to psychological symptoms such as family and social conflicts, stress due to unmet responsibilities, anxiety, and irritability. This problem has become especially critical among young people. A 2025 meta-analysis found the prevalence of social media addiction among university students to be 18.4% and reported negative effects on academic achievement. Research also shows that social media addiction is associated with decreased self-esteem, emotion regulation difficulties, and dysfunctional interpersonal relationships. Social comparison tendencies and idealized digital identity presentations further harm young individuals' self-perceptions, contributing to low self-esteem and social anxiety.
Interpersonal difficulties experienced in relationships are defined as "interpersonal problems," while the cognitive-behavioral processes used to resolve these difficulties are called "interpersonal problem solving." These skills are essential for effective conflict resolution, social adaptation, relationship quality, and overall well-being. Social media shapes both the emergence and resolution of interpersonal problems; however, current knowledge in this area is limited. Excessive use contributes to interpersonal conflicts, deterioration of relationships, and reduced face-to-face communication. Thus, social media addiction may impair interpersonal problem-solving skills by disrupting daily functioning.
Although the literature includes correlational studies on social media addiction, self-esteem, and interpersonal functioning, research testing Acceptance and Commitment Therapy (ACT)-based psychoeducation remains scarce. This study offers a theoretical contribution by applying a third-wave therapy approach to the psychosocial challenges of the digital age. It aims to evaluate the effects of an ACT-based psychoeducation program developed for young individuals with social media addiction on self-esteem and interpersonal problem-solving skills. Given the limited number of such programs in Türkiye, this study is original and aims to fill an important gap in the literature.
