Clinical trials

Periodontal disease is a chronic inflammatory condition that affects the tissues supporting the teeth and may contribute to systemic inflammation and oxidative stress. Increasing evidence suggests that maternal inflammation during pregnancy may be associated with adverse pregnancy outcomes, including preterm birth. However, the biological mechanisms linking maternal periodontal inflammation to the intrauterine environment remain unclear. This prospective observational cohort study aims to investigate the relationship between maternal periodontal status and inflammatory and oxidative stress biomarkers measured in both saliva and amniotic fluid. Eighty healthy pregnant women between 28 and 32 weeks of gestation will be recruited from the Obstetrics and Gynecology Clinic of Gulhane Training and Research Hospital. Participants will undergo a comprehensive periodontal examination and provide unstimulated saliva samples. Amniotic fluid samples will be collected during delivery as part of routine obstetric care, without any additional invasive procedures. The concentrations of 8-hydroxy-2'-deoxyguanosine (8-OHdG), malondialdehyde (MDA), interleukin-6 (IL-6), and matrix metalloproteinase-8 (MMP-8) will be measured in saliva and amniotic fluid using enzyme-linked immunosorbent assay (ELISA). Pregnancy outcomes, including gestational age at delivery, birth weight, and pregnancy complications, will also be recorded. The study will evaluate whether maternal periodontal inflammation is associated with changes in inflammatory and oxidative stress biomarkers in saliva and amniotic fluid and whether these biomarkers are related to pregnancy outcomes. The findings may improve understanding of the biological relationship between oral health and pregnancy and may contribute to the identification of biomarkers associated with adverse pregnancy outcomes.

Purpose: This study aims to evaluate the effects of an educational digital escape room game-based Psychological First Aid (PFA) training on the PFA self-efficacy and problem-solving levels of undergraduate midwifery students.

Breast milk is considered the most biologically appropriate source of nutrition, essential for the healthy growth and development of newborns. Thanks to its optimal nutrients, immunological factors, and growth regulators, it not only meets nutritional needs but also protects against infections, reducing neonatal morbidity and mortality rates. The Pecha Kucha presentation technique keeps presentations concise and dynamic, creating a fast-paced, light, and engaging experience. It minimizes distractions and maximizes engagement. Because there is no text to read in the Pecha Kucha technique, presenters are required to be more prepared and strive to create a coherent narrative, resulting in a flawless narrative. Thus, the aim is to ensure the success and effectiveness of breastfeeding education with this technique, and ultimately, to promote breastfeeding education using the Pecha Kucha technique to healthcare professionals. The population of this randomized, controlled experimental study consists of primiparous postpartum women who gave birth in the Obstetrics Department of the Physical Therapy Annex Building of the Gaziosmanpaşa Training and Research Hospital at the University of Health Sciences. A power analysis was conducted using the G\*Power package program, Version 3.1.9.4, to determine the sample size of the study. Because no similar research was found in the literature, Cohen's medium effect size was chosen as the effect size, anticipating that tests assessing the difference between two independent groups would be used when examining the differences in variables between the control and intervention groups. Accordingly, with 64 participants in the control group and 64 in the intervention group, a power of 80% was calculated at a significance level of 0.5 (medium) effect size and 0.05, and a minimum sample size of 128 was determined. The study, planned using an experimental design, is planned to be conducted on two groups: an intervention and a control group. Within the scope of the study, pretest data will be collected by administering the Breastfeeding Self-Efficacy Scale and the LATCH Breastfeeding Diagnostic and Assessment Scale, along with an introductory information form, to postpartum women who agree to participate in the study.

Postoperative pain following coronary artery bypass grafting (CABG) via median sternotomy remains a significant clinical problem and is associated with increased opioid consumption and postoperative complications. Fascial plane blocks have emerged as part of multimodal analgesia strategies in cardiac surgery.

This prospective observational clinical study aims to evaluate the three-dimensional surface wear and clinical survival of orthodontic attachments fabricated with customized composite materials used in clear aligner therapy. Attachments play a critical role in the biomechanical efficiency of aligner treatment by facilitating planned tooth movements. However, the mechanical and surface properties of the composites used for attachment fabrication may affect their wear behavior and long-term stability. In this study, four different composite materials will be tested using a split-mouth design in patients treated with clear aligners. Each quadrant will receive a different composite, including both customized and universal types. All attachments will be fabricated using standardized digital templates and bonded under identical clinical conditions. Surface wear will be evaluated using three-dimensional optical scanning and metrology software at baseline, 1 week, 1 month, 3 months, and 6 months. Lost attachments will be replaced and recorded but excluded from wear analysis. The results of this study are expected to provide valuable insights into the optimal material selection for clear aligner attachments, improving treatment accuracy and clinical durability.

The widespread use of electronic devices such as smartphones, tablets, and laptops has significantly increased screen exposure, especially before sleep.

With the global aging trend, the management of geriatric risks faced by older adults and the effectiveness of health education for this population are gaining increasing importance. Literature indicates that health education for older adults, when delivered through methods that support individual engagement and the use of digital tools, yields more effective results in terms of learning and behavior change. This doctoral study aims to evaluate the effect of a digital education model, structured based on the Health Belief Model and developed using branching scenario animation technique, on geriatric risk knowledge level and frailty status among older adults residing in nursing homes. The study will be conducted as a randomized controlled trial in three nursing homes in Istanbul, with measurements at baseline (T0), immediately post-intervention (T1), 1-month follow-up (T2), and 3-month follow-up (T3). Based on power analysis, 66 participants will be randomly assigned to intervention and control groups (33 per group) using block randomization. The intervention group will receive scenario-based digital animation education developed on the Vyond platform and structured according to the theoretical components of the Health Belief Model. The control group will receive standard care during the study period and will be offered the same digital animation education after completion of all assessments (post 3-month follow-up). The primary outcome is geriatric risk knowledge level, assessed using an interactive digital game called "Knowledge Wheel." Secondary outcomes include frailty status, measured by the Edmonton Frail Scale, and technology acceptance. Changes in knowledge and frailty levels measured through assessment tools will reveal the short- and medium-term effects of the education. Thus, the model's impact on health-related behavior change in older adults will be comprehensively evaluated. The unique aspect of this study is that it will be one of the first experimental studies to implement an interactive scenario-based digital education model in older adults. The findings are expected to contribute to the development of age-friendly health education models.
