Neurotrophic Factors, Impulsivity, and Reward Sensitivity in Children With Internet Gaming Disorder

Research and knowledge regarding the neurobiology of behavioral addictions and Internet Gaming Disorder (IGD) remain limited compared to substance and alcohol use disorders. However, IGD is increasingly causing significant functional impairment, particularly in the child and adolescent population. The primary objective of this study is to measure the serum levels of Brain-Derived Neurotrophic Factor (BDNF) and Glial-Derived Neurotrophic Factor (GDNF)-both known for their roles in neurogenesis and neuroprotective effects-in a patient group aged 10-14 and a healthy control group. Additionally, this study aims to investigate the relationship between these neurotrophic factor levels and disease severity, as well as various behavioral and emotional parameters measured through psychometric assessments, to identify differences between the patient and healthy populations. Researchers will compare IGD patient group with healthy control group, both aged 10-14. Participants and their parents will be asked to fill self-report measures and serum samples of participants will be collected for BDNF and GDNF level measurements. The main questions of the study are: * Is there a difference in serum BDNF and GDNF levels between IGD patient group and healthy controls? * Is there a relation between serum BDNF and GDNF levels and IGD severity? * Is there a difference in impulsivity, reward/punishment sensitivity between IGD patient group and healthy controls * Is there a relation between serum BDNF and GDNF levels and impulsivity, reward/punishment sensitivity scores in IGD patient group?

Comparison of Sports Anxiety, Sports Injury Anxiety, and Knowledge Levels Regarding Factors Causing Sports Injury in Individuals Who Regularly Engage in Conditioning Work With and Without a History of Injury

Anxiety, or anxiety disorder, is a common occurrence today. Studies have proven that sports have a high potential for stress and anxiety. Among the reasons for its prevalence in athletes are performance pressure, public scrutiny, dissatisfaction with athletic careers, injuries, and harassment and abuse in sports. Anxiety can negatively impact performance and competition results. However, the relationship between anxiety and performance has not been fully established. Studies on the relationship between anxiety and injury in athletes are also increasing. However, studies examining injury history and sports anxiety levels in individuals who regularly perform conditioning exercises are lacking. Based on our literature review, our study will ask individuals who regularly engage in conditioning training about their injury history. Participants will be divided into two groups: those with and those without injuries. The two groups will be compared in terms of their sports anxiety and fear of injury, and their knowledge of the factors that contribute to injuries in sports will be measured.

Bacteria in Dental Plaque and Atheroma Plaque

Periodontitis is considered a focus of infection where oral bacteria, bacterial by-products or inflammatory mediators can interact with other parts of the organism via the blood. Periodontal pathogen components such as DNA, RNA or specific antigens of P. gingivalis, Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans), Treponema denticola (T. denticola), Fusobacterium nucleatum (F. nucleatum) or Campylobacter rectus have been isolated from different tissues such as atheroma plaques, placenta, amniotic sac and respiratory tract. It has been reported that periodontitis may contribute to endothelial dysfunction leading to the formation of atherosclerosis.

Aromatherapy and Music on Pain, Vital Signs and Parental Satisfaction in Children Undergoing Peritoneal Dialysis

This study is an experimental randomized controlled study conducted to compare the effect of two different nonpharmacological treatment methods (aromatherapy and music therapy) on pain, vital signs and parental satisfaction to alleviate or eliminate pain during excretion and filling in children undergoing peritoneal dialysis treatment. The study population consists of pediatric patients aged 3 to 18 years undergoing peritoneal dialysis treatment at Basaksehir Cam and Sakura City Hospital between June 2025- 2026. According to literature, for experimental studies and parametric measurements, at least 30 participants should be included in both experimental and control groups. Therefore, this crossover randomized design will include 45 children per group: control, aromatherapy, and music therapy. Children included in the sample will be assigned to groups based on a crossover randomized design. This method is suitable for studies with a small sample size. Since three different interventions will be applied once per session over three sessions, to avoid bias, the order of interventions will be randomized and labeled as A, B, and C. The researcher will write the names of the interventions on three separate papers, draw them one by one, and assign them accordingly: Method A: Aromatherapy, Method B: Music Therapy, Method C: Control. Then, the six possible sequences (ABC, ACB, BAC, BCA, CAB, CBA) will be written on six papers and drawn randomly to determine the intervention order for each participant.

ABCDEF Bundle to Prevent Delirium for COPD Patients

Abstract Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disorder characterized by persistent airflow limitation and chronic respiratory symptoms, resulting from abnormalities in the bronchi, bronchioles, and alveoli. Patients with COPD may require admission to intensive care units (ICUs), particularly during acute exacerbations. In this context, both disease management and the prevention of potential complications, such as delirium, are of critical importance. Delirium is a common, preventable, and serious complication in ICUs that prolongs hospital stays, increases healthcare costs, and heightens the risk of infections. Hypoxia-induced cognitive impairment is among the key contributing factors to delirium in patients with COPD. To improve patient outcomes, the ABCDEF Care Bundle was introduced in 2013 as a structured and evidence-based approach to ICU care. This study aims to evaluate the effectiveness of the ABCDEF Care Bundle in preventing delirium in patients with COPD admitted to the ICU. The research will be conducted as a randomized controlled trial between April and December 2025 in the third-level ICU of Taksim Training and Research Hospital. The study population will consist of COPD patients, with a total sample size of 84 patients (42 in each group), randomly assigned using a computer-assisted simple randomization method. A variety of validated instruments will be used to assess pain, sedation, cognitive status, mobility, and sleep quality. The findings of this study are expected to contribute to the growing body of evidence supporting structured ICU care and to raise awareness among healthcare professionals regarding the implementation of the ABCDEF Care Bundle.

Patients With Irritable Bowel Syndrome and Physiotherapy

The research will be planned on 72 individuals between the ages of 18-65 who were diagnosed with irritable bowel syndrome at Istanbul Medipol University Çamlıca SUAM Gastroenterology Polyclinic. Patients will be divided into 3 groups; High-intensity interval training and a disease-specific nutrition program for the first group, and a disease-specific nutrition program for the second group; Basic Body Awareness Therapy (BBAT) and a disease-specific nutrition program will be given, while the control group will be given only a disease-specific nutrition program. Evaluations will be made immediately before and after treatment. The first experimental group will be asked to walk with high-intensity interval training, which the investigators plan for 30 minutes, 4 days a week for 8 weeks. TBFT will be applied to the second experimental group every day of the week. The application will be done face to face one day a week, and the patient will be asked to do it himself on the other days, and the sessions will last approximately 30 minutes. In addition, all patients will be asked to follow the nutrition program determined by the dietician. Participants' sociodemographic information, IBS disease type and medications used will be recorded. In order to collect data for both the intervention groups and the control group immediately before and after the study; 6 Minute Walk Test (6MWT), posture analysis, muscle shortness test for large muscle groups in the lower and upper extremities, International Physical Activity Questionnaire Short Form (IPAQ-SF), Diet Compliance Questionnaire Form, Bristol Stool Scale Form, Gastrointestinal Symptom Assessment Scale (GSDS). ), Pittsburgh Sleep Quality Index (PSQI), IBS Quality of Life Scale (IBS-QOL), Morningness-Eveningness Questionnaire (SAA), Psychological Well-Being Scale (PIOS) and Body Awareness Questionnaire (VFA) will be used.

Effect of Normothermia Care Bundle in Knee Replacement Surgery

Osteoarthritis is a disease characterized by disruption of the integrity of articular cartilage as a result of erosion of articular cartilage. Knee osteoarthritis causes muscle weakness, crepitation and deformities in the knee joint, limiting the individual's movement and causing loss of function. The most prominent feature is pain. Therefore, knee replacement surgery is performed in advanced cases where pharmacologic treatment is not effective. Many complications can be seen during the operation process and some of them may occur due to hypothermia. Studies have reported that warming during the operation prevents hypothermia and reduces complications. In this study, it was aimed to examine the effect of active and passive heating applied before, during and after surgery on hypothermia, surgical site infections and bleeding. The population of the study will consist of patients who underwent knee replacement surgery in the Orthopedics and Traumatology Clinic of Üsküdar State Hospital between April 2024 and April 2025. Data will be collected using the patient identification form, normothermia care package observation form, preoperative follow-up form, postoperative follow-up form and postoperative long-term follow-up form. A randomization list generated from a computer-based random numbers table will be used to determine which group of patients will be included in the study. Patients will be followed up in 3 periods: preoperative, intraoperative and postoperative periods. The postoperative period will be evaluated in five stages as day 1, day 2, day 3, day 10 and day 30. The purpose of the study and the intervention to be applied will be explained to all groups to be included in the study by the researcher and written and verbal consent will be obtained from the volunteers. The groups included in the study will be subjected to the heating protocol according to the normothermia care package. Group A will receive active heating with the heating method using a hot air blowing device. Group B will receive passive heating using a reflective blanket. Group C was planned as a control group to be heated by applying the routine heating procedure of the hospital without any intervention. Body temperature and vital signs will be checked preoperatively and warming will be performed 30 minutes before surgery, and warming will be started 15 minutes before anesthesia induction during surgery and body temperature and vital signs will be checked. After the operation and in the ward, warming will be performed until the body temperature reaches 37 C°. The data obtained will be analyzed using SPSS (Statistical Package for Social Sciences) for Windows 22.0 program.
