COLORING ACTIVITY APPLIED DURING LABOR IN PRIMIPAROUS PREGNANT WOMEN AND ITS EFFECT ON BIRTH ANXIETY AND FEAR OF CHILDBIRTH.

This randomized controlled trial aims to evaluate whether a mandala coloring activity during labor can reduce birth anxiety and fear of childbirth among primiparous pregnant women experiencing their first birth. The study will be conducted among eligible primiparous women admitted to the delivery unit at Şanlıurfa Training and Research Hospital during active labor. A total of 140 primiparous pregnant women will be randomly assigned to either an intervention group or a control group. Women in the intervention group will receive standard labor care in addition to a structured mandala coloring activity beginning when cervical dilation is between 5 and 8 cm. Participants will be provided with standardized mandala drawings and coloring pencils and will be encouraged to color during contractions as tolerated until birth. Women in the control group will receive routine labor and obstetric care without an additional art-based or distraction intervention. Routine maternal and fetal monitoring will continue in both groups throughout labor. Birth-related anxiety and fear will be assessed before the intervention during the active phase of labor and after birth. The study will use validated measures to evaluate fear of childbirth and birth-related anxiety. The study will also record relevant obstetric outcomes, including mode of delivery, analgesia use, and duration of labor. The study seeks to answer whether adding a simple, low-cost, non-pharmacological mandala coloring activity to routine labor care can reduce birth anxiety and fear of childbirth in primiparous women. The findings may provide evidence for the use of accessible, non-pharmacological supportive interventions as part of midwifery care during labor.

Menopause and Compassionate Living Education

Menopause is a natural stage in a woman's life characterized by the permanent cessation of ovarian function and is frequently accompanied by vasomotor, psychological, urogenital, and sleep-related symptoms that can substantially impair quality of life. Although pharmacological treatments are available, many women seek non-pharmacological interventions to manage menopausal symptoms and improve their overall well-being. Mindfulness- and compassion-based interventions have shown promising effects on psychological health, stress reduction, and quality of life in different populations; however, evidence regarding the effectiveness of Mindfulness-Based Compassionate Living (MBCL) for women experiencing menopause remains limited. This randomized controlled trial aims to evaluate the effectiveness of a Compassionate Living Education Program based on the principles of Mindfulness-Based Compassionate Living in improving symptom management and quality of life among menopausal women. The study will be conducted with menopausal women recruited from primary healthcare settings in Kars, Türkiye. Participants who meet the eligibility criteria will be randomly assigned to either an intervention group or a control group. Participants in the intervention group will receive an eight-session online Compassionate Living Education Program delivered by a certified instructor. The program includes mindfulness practices, self-compassion exercises, breathing and relaxation techniques, compassionate imagery, loving-kindness meditation, and home practice assignments designed to strengthen emotional regulation, self-kindness, and adaptive coping skills. The control group will receive routine care only. Primary outcomes will include menopausal symptom severity and menopause-specific quality of life. Secondary outcomes will include self-compassion, mindfulness, anxiety, depression, and stress. Data will be collected using validated self-report questionnaires before and after the intervention and analyzed using appropriate statistical methods. The findings of this study are expected to provide evidence regarding the effectiveness of Compassionate Living Education as an accessible, low-cost, non-pharmacological intervention for improving symptom management and enhancing the quality of life of menopausal women. The results may contribute to the development of evidence-based nursing and women's health interventions in primary healthcare settings.

The Effect of Intravenous Injection Training Based on the ARCS-V Model on Levels of Learning Motivation and Self-Efficacy

Intravenous (IV) administration, one of the most fundamental and common practices carried out by nurses, is defined as the administration of medication directly into the circulatory system via a vein. Intravenous administration is one of the key clinical skills that must be performed using the correct technique. Supporting students' motivation to learn plays a significant role in the effective acquisition of this skill. The ARCS-V motivation model, which aims to enhance motivation during the teaching process, comprises the dimensions of attention, relevance, confidence, satisfaction and action. This study aims to investigate the effect of intravenous administration training based on the ARCS-V model on nursing students' levels of motivation and academic self-efficacy. The study will be conducted using a mixed-methods design incorporating both a randomised controlled trial and qualitative research methods. In the study, the experimental group will receive IV administration training structured according to the ARCS-V model, whilst the control group will be taught using the traditional teaching method. For the collection of quantitative data in this study, the "Demographic Information Form", the "Motivation Scale for Teaching Materials (ÖMMÖ)", the "Academic Self-Efficacy Scale (AÖÖ)" and the "Volition to Learn Scale (VFLS)" will be used. For the collection of qualitative data in the study, a "Semi-Structured Interview Form" will be used to determine the experiences of students in the experimental group regarding the learning process, and an audio recorder will be used to record the data. Whilst the quantitative data obtained will be analysed using statistical methods, the qualitative data will be evaluated through content analysis. It is anticipated that the findings of this research will demonstrate that teaching based on the ARCS-V model contributes to clinical skills training by supporting students' active participation in the learning process, as well as their motivation and will to learn.

Relationship Between Metrnl Expression, IL-1β, and TNF-α in Patients With Peri-Implantitis

Peri-implantitis is an inflammatory disease affecting the tissues around dental implants and may lead to progressive bone loss and implant failure. Current diagnosis is mainly based on clinical and radiographic findings, which may not fully reflect the underlying inflammatory activity. Therefore, there is a need for biological markers that may provide additional information about disease-related changes. This observational study aims to compare the levels of Meteorin-like protein (Metrnl) and selected inflammatory cytokines in peri-implant crevicular fluid obtained from individuals with peri-implantitis and individuals with healthy implants. The study will evaluate Metrnl, interleukin-1 beta (IL-1β), tumor necrosis factor-alpha (TNF-α), and interleukin-10 (IL-10). It will also examine the relationships between Metrnl and these inflammatory markers. The study hypothesis is that Metrnl levels differ between healthy peri-implant tissues and peri-implantitis and are associated with pro-inflammatory and anti-inflammatory cytokine levels. The findings may help clarify the possible role of Metrnl in peri-implant inflammation and its potential as a biomarker for distinguishing peri-implant health from peri-implantitis.

Effects of Oxygen Cage Support During Cataract Surgery

Cataract is an ocular disorder resulting from lens opacity; it stands as the most common cause of preventable blindness worldwide and significantly impairs the quality of life in elderly individuals. Surgical treatment utilizing small-incision phacoemulsification is the most effective solution for cataracts. Cataract surgery is generally performed under local anesthesia, which requires patients to remain awake throughout the operation, thereby potentially increasing their anxiety experiences. Elevated anxiety not only reduces patient comfort but can also lead to alterations in physiological parameters and a prolongation of the operation time. Furthermore, it is observed that the surgical drapes used to maintain the sterility of the surgical field during the operation cause discomfort to the patient. The weight and positioning of these drapes can cover the patient's mouth and nose area during the ongoing surgery, creating a sensation of difficulty in breathing (dyspnea). In addition to these circumstances, standard oxygen support is provided to the patient during cataract surgery performed under local anesthesia. This support is administered nasally via an open-ended oxygen tubing from beneath the surgical drape, aiming to ease the patient's respiration. However, when the oxygen flow rate is increased based on the patient's needs, high-velocity and high-concentration oxygen administration is observed to cause mucosal dryness, which shortly triggers reflex-induced irritative coughing attacks. For these reasons, it is crucial to keep anxiety under control, provide oxygen to prevent hypoxia, and monitor physiological parameters during cataract surgery.

Artificial Intelligence Powered Digital Education Based on the Neuman Systems Model for Breast Cancer Patients Receiving Radiotherap

The purpose of this clinical trial is to evaluate the effect of an artificial intelligence-supported digital education program developed based on the Neuman Systems Model on radiodermatitis severity and quality of life in women with breast cancer receiving radiotherapy. The intervention was developed based on the Neuman Systems Model, which served as the theoretical framework of the study. Educational content was structured according to the principles of the model and was designed to strengthen patients' flexible lines of defense, support resistance resources, facilitate adaptation to radiotherapy-related stressors, and promote system stability through primary, secondary, and tertiary prevention strategies. The study aims to answer the following questions: * Is a Neuman Systems Model-based AI-supported digital education program effective in reducing the severity of radiotherapy-induced radiodermatitis? * Is a Neuman Systems Model-based AI-supported digital education program effective in improving quality of life among women receiving radiotherapy for breast cancer? Participants assigned to the intervention group will be provided with access to the AI-supported digital education program developed in accordance with the Neuman Systems Model, whereas participants assigned to the control group will receive standard care. Differences between the groups with respect to radiodermatitis severity and quality of life outcomes will be evaluated. Participants will complete a Patient Information Form to collect sociodemographic and clinical characteristics prior to the initiation of radiotherapy. Radiodermatitis severity will be assessed using the Radiation Therapy Oncology Group (RTOG) Acute Radiation Dermatitis Scale, and quality of life will be evaluated using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and the breast cancer-specific module (EORTC QLQ-BR23). Following these assessments, participants will be randomly allocated to either the intervention group or the control group. Radiodermatitis severity will be evaluated weekly throughout the radiotherapy period using the RTOG scale and reassessed two weeks after completion of radiotherapy. Quality of life will be evaluated before radiotherapy and reassessed two weeks after completion of radiotherapy using the EORTC QLQ-C30 and EORTC QLQ-BR23 questionnaires. Participants assigned to the intervention group will be provided with access to an AI-supported digital education platform incorporating educational modules, personalized educational recommendations, reminder notifications, and motivational messages. In addition, system usability will be evaluated at the end of the intervention period using the System Usability Scale (SUS).

Effect of iPACK and BiFeS Blocks on Quality of Recovery After Total Knee Arthroplasty

This prospective, randomized, double-blind clinical trial aims to compare the effects of two different posterior knee analgesia techniques-iPACK block (Interspace Between the Popliteal Artery and the Capsule of the posterior Knee) and the Biceps Femoris Short Head (BiFeS) block-when combined with an adductor canal block (ACB) in patients undergoing elective unilateral total knee arthroplasty (TKA). Effective postoperative analgesia is essential for early mobilization, enhanced recovery, and patient satisfaction after TKA. Although ACB provides good anterior knee analgesia while preserving quadriceps strength, additional posterior knee analgesia is often required. The iPACK block is a commonly used technique that targets the posterior knee capsule, whereas the newer BiFeS block aims to provide more selective posterolateral sensory blockade with potentially reduced risk of motor involvement. However, comparative clinical data between these two techniques are limited. The primary objective of this study is to evaluate the difference between the iPACK and BiFeS blocks in terms of Quality of Recovery-15 (QoR-15) scores at 24 hours postoperatively. Secondary objectives include comparisons of postoperative pain scores, opioid consumption, time to first analgesic request, quadriceps and anterior tibialis muscle strength, functional test performance, time to mobilization, active range of motion, and the incidence of adverse events. A total of 74 adult patients scheduled for elective unilateral TKA under spinal anesthesia will be randomized in a 1:1 ratio into two groups: ACB + iPACK block or ACB + BiFeS block. All blocks will be performed under ultrasound guidance by an experienced anesthesiologist. Outcome assessments will be conducted by blinded investigators. The study aims to provide high-quality clinical evidence regarding the effectiveness of the BiFeS block compared to the widely used iPACK technique.

Bupivacaine-Lidocaine vs Bupivacaine for Ultrasound-Guided Popliteal Sciatic Nerve Block

This prospective, randomized, double-blind clinical trial aims to compare the efficacy of two local anesthetic regimens for ultrasound-guided popliteal sciatic nerve block in adult patients undergoing elective distal lower extremity surgery. Eligible participants (ages 18-65, ASA physical status I-III, BMI 18-35 kg/m²) will be randomized into two equal groups of 30. Patients in Group BL will receive a combination of 10 mL 2% lidocaine and 10 mL 0.5% bupivacaine, while patients in Group B will receive 20 mL 0.5% bupivacaine alone, administered via ultrasound-guided popliteal sciatic nerve block prior to surgery. The primary outcome is the onset time of sensory and motor blockade. Secondary outcomes include block success rate, duration of sensory and motor block, postoperative opioid consumption, pain scores assessed by the Numeric Rating Scale (NRS) at 2, 4, 8, 12, and 24 hours postoperatively, Quality of Recovery-15 (QoR-15) score, and incidence of rebound pain. The study is conducted at Ataturk University Research Hospital, Department of Anesthesiology and Reanimation, Erzurum, Turkey.

The Effect of Escape Room-Based Elimination Training on Student Outcomes

This clinical trial aims to find out if playing an "educational escape room" game helps nursing students better learn how to manage patient elimination (urinary and bowel care). The study looks at how this game affects students' knowledge, hands-on skills, their desire to learn (motivation), and how happy they are with the training (satisfaction). The main questions the researchers want to answer are: Does the escape room game help students understand the rules and steps of elimination care better than traditional lessons? Does this method improve students' practical skills in tasks like inserting catheters, giving enemas, and performing stoma care? How does the game affect students' motivation to learn and their overall satisfaction with the nursing program? Researchers will compare students who use the educational escape room with students who learn through traditional methods to see if the game makes a real difference in their performance. Participants in this study will: Learn the theory behind bowel and bladder care (such as enemas and catheterization). Work in small groups to solve puzzles and find clues inside a themed room to complete patient care tasks. Take knowledge tests and practical "skill exams" after the training. Fill out surveys about how motivated they felt and how much they enjoyed the learning experience.

Serum Cholinesterases, Paraoxonase, and Cardiovascular Risk After Intravitreal Bevacizumab

Bevacizumab, an anti-VEGF (vascular endothelial growth factor) agent used in the treatment of diabetic retinopathy and macular edema associated with retinal vein occlusion, is commonly administered in ophthalmology clinics through intravitreal injection. The systemic use of bevacizumab has been associated with serious conditions such as thromboembolism and bleeding. Although intravitreal bevacizumab is administered in smaller amounts and has limited systemic circulation, it requires repeated injections over a long period. These long-term intravitreal anti-VEGF therapies may lead to adverse outcomes, particularly thromboembolism, due to systemic inhibition of VEGF. However, limited information is available regarding the potential effects of this treatment on the systemic and cardiovascular systems. To evaluate this risk, the study aims to assess changes in the activities of paraoxonase 1 (PON1), acetylcholinesterase (AChE), and butyrylcholinesterase (BChE), which are closely associated with lipid metabolism, coronary artery disease, and atherosclerosis. These enzymes are known biomarkers of cardiovascular health and play significant roles in protection against oxidative stress and inflammation. For this purpose, a case-control study is planned. Serum BChE and PON1 activities, as well as triglyceride (TG)/high-density lipoprotein (HDL) and TG/glucose ratios, will be determined in patients receiving repeated intravitreal bevacizumab injections and in control groups, and cardiovascular disease risk will be assessed. This study may help us better understand the safety profile of this treatment by revealing the effects of bevacizumab on serum enzyme activities and cardiovascular risk factors. These findings could contribute to optimizing treatment strategies in clinical practice.

The Effect of Hologram Application on Pain, Anxiety, and Fear Levels in Children During Burn Dressing

The process of dressing burn injuries has been shown to cause both physical and psychological difficulties. In children, this process is particularly associated with intense pain and anxiety. Consequently, in addition to pharmacological interventions, non-pharmacological methods such as distraction are employed. In recent years, the utilization of holograms as a method of alleviating pain has emerged as a novel approach. The employment of these visual illusions has been demonstrated to effectively distract children, thereby providing a means of reducing discomfort. The objective of this thesis is to evaluate the effects of hologram application on pain, anxiety, fear, and vital signs during burn dressing in children.
