Hyperangulated vs Standard Videolaryngoscopy vs Direct Laryngoscopy for Double-Lumen Endobronchial Tube Intubation

This is a prospective, randomized, single-center, three-arm, open-label, low-risk medical device clinical study conducted at the Department of Anesthesiology and Reanimation, Trakya University Medical Faculty. The study aims to compare the efficacy, safety, and clinical usability of three laryngoscopy methods for double-lumen endotracheal tube (DLT) intubation in patients undergoing elective thoracic surgery requiring one-lung ventilation: (i) C-MAC hyperangulated (D-blade) videolaryngoscopy, (ii) C-MAC Macintosh blade videolaryngoscopy, and (iii) direct Macintosh laryngoscopy. The primary outcome is the total time to successful DLT placement (in seconds), defined as the interval from the end of mask ventilation to fiberoptic bronchoscopic confirmation of correct tube position. Secondary outcomes include glottic visualization quality (POGO score and Cormack-Lehane grade), intubation difficulty (Intubation Difficulty Scale), number of intubation attempts, need for auxiliary maneuvers, intubation-related complications, malposition rate, and postoperative airway symptoms (sore throat, dysphonia) assessed at 1, 6, and 24 hours postoperatively. Eligible patients are adults (≥18 years), ASA class I-III, scheduled for elective thoracic surgery requiring one-lung ventilation. Patients with anticipated difficult airway, emergency surgery, pregnancy, or prior upper airway surgery are excluded. A total of 180 patients will be enrolled and randomized 1:1:1 into three groups (60 per group) using computer-generated block randomization.

Frailty and Nottingham Hip Fracture Score for Predicting 90-Day Mortality After Hip Fracture Surgery

Hip fractures are serious injuries that occur mostly in older adults. Many people experience health problems or may die in the months after surgery. Doctors try to identify patients who have a higher risk of poor outcomes as early as possible. Doctors often use the Nottingham Hip Fracture Score (NHFS) to estimate the risk of death after hip fracture surgery. This score uses information such as age and other health conditions. However, it does not fully reflect how physically vulnerable a person may be. Another important concept is frailty. Frailty describes how strong or weak a person's overall health and physical reserve are. In this study, frailty will be measured using the Clinical Frailty Scale (CFS). This scale evaluates a person's level of independence and physical function before the fracture. The purpose of this study is to determine whether measuring frailty can improve the prediction of death after hip fracture surgery. Older adults with hip fractures who undergo surgery will be invited to participate in the study. Researchers plan to include about 200 participants or all eligible patients enrolled within one year, whichever occurs first. Health information that is already collected during routine hospital care will be recorded. Frailty will be assessed when participants are admitted to the hospital. Participants will be followed for 30 days and 90 days after surgery to determine survival status. Researchers will review hospital records and may contact participants or their relatives by phone if needed. The results of this study may help doctors better identify patients at higher risk and improve care planning after hip fracture surgery.

The Effects of Kinesio Taping on Heel-Rise Endurance and Gastrocnemius Muscle Oxygenation in Healthy Young Adults

acilitative kinesio taping (KT) is commonly used by athletes to support muscle performance and delay fatigue. However, evidence regarding its effects on muscle endurance and oxygenation remains inconsistent. This study aims to investigate the acute effects of facilitative KT applied to the gastrocnemius muscle on heel-rise endurance performance and local muscle oxygenation in healthy young adults. In this randomized crossover trial, participants will complete two experimental sessions: one with facilitative kinesio taping and one with sham taping. After taping application, participants will perform a single-leg heel-rise test to task failure. Muscle oxygenation will be continuously monitored using a portable near-infrared spectroscopy device. The findings of this study may contribute to understanding whether kinesio taping has immediate physiological and performance-related effects on calf muscle endurance.

Pinwheel and Bubble Blowing for Pain and Emotional Responses in Children

Venous blood sampling is one of the most frequently performed invasive procedures in children during diagnostic and treatment processes and may lead to pain, fear, and negative emotional responses. Such negative experiences in childhood may contribute to the development of anxiety toward healthcare services and reduced cooperation with healthcare professionals during treatment. Therefore, the use of non-pharmacological interventions aimed at reducing pain levels and emotional responses during procedures is of great importance in pediatric care. The aim of this study is to determine the effects of pinwheel and bubble blowing techniques applied during venous blood sampling on pain levels and emotional states in children. This study will be conducted as a prospective, randomized controlled trial in the Blood Sampling Unit of the Pediatric Outpatient Clinic of a university hospital located in Edirne. A total of 66 children aged 3-6 years who will undergo venous blood sampling will be included in the study (pinwheel group: 22, bubble blowing group: 22, control group: 22). Study data will be collected using the Child and Family Information Form, the Wong-Baker Faces Pain Rating Scale, and the Children's Emotional Indicators Scale. During venous blood sampling, pinwheel or bubble blowing techniques will be applied to the children in the experimental groups, while routine procedures will be performed for the children in the control group. The collected data will be analyzed using appropriate statistical methods. The results of this study are expected to contribute to the dissemination of evidence-based non-pharmacological practices aimed at reducing pain and emotional stress in pediatric nursing care.

3D Volumetric Plaque Assessment on Teeth, Composite Restorations, and Ceramic Veneers Using an Intraoral Scanner

The goal of this observational study is to evaluate and compare a 3D intraoral scanner-based, computer-assisted approach for assessing dental biofilm/plaque accumulation on natural teeth and restorative surfaces with a conventional clinical plaque index (Turesky modified Quigley-Hein Plaque Index, TMQHPI) in systemically healthy adults. The main questions it aims to answer are: * How well does the plaque-covered surface measurement derived from 3D intraoral scanner data agree with TMQHPI scores after plaque disclosure? * How sensitively do the two methods detect changes in plaque levels after supervised toothbrushing? * Do plaque accumulation patterns differ between natural tooth surfaces and restorative materials (direct composite restorations and indirect ceramic veneers), and where are plaque-retentive areas most frequently located? Participants (≥18 years) will receive routine professional mechanical plaque removal as part of standard clinical care. They will then be asked to avoid mechanical and/or chemical plaque control for 4 days. At the follow-up visit, participants will undergo: 1. An intraoral scan and standardized photographs of the full dental arch, 2. Plaque disclosure followed by repeat scanning/photography and TMQHPI scoring by a periodontist, 3. Supervised toothbrushing using the modified Bass technique for 2 minutes, followed by a final scan and photographs. Digital models will be used to quantify plaque-covered surface measures and to generate 3D maps of plaque-retentive areas.

3-Dimensional Evaluation of Body Perception

The goal of this observational study is to evaluate the changing body perception of amputees aged 18-65 years using prostheses through different personal perspectives of the right-left distinction. In addition, we aimed to examine the relationship between possible changes in body perception and visual spatial perception and neurocognitive performances. The main questions that this study aimed to answer are as follows: 1. Is there a difference between the amputee group and the control group in terms of parameters related to body perception? 2. Is there a difference between the amputee group and the control group in terms of neurocognitive skills? 3. Is there any difference between the amputee group and the control group in terms of visual spatial perception abilities? To examine whether changes in body perception in amputees affect neurocognitive performance, visuospatial perception and perspective perception and the relationship between them will be compared with a healthy control group. The assessments to be applied to both groups can be summarised as follows: * Demographic information such as age, gender, and education level will be recorded. * Mini-mental state test will be used to assess the cognitive level. * Edinburgh Handedness Scale will be used to determine the dominant side. * Right-left discrimination and personal perspective perception will be assessed using a desktop programme. * The clock drawing test and Benton line orientation test will be used to visual spatial perception. * A computer based program called The Central Nervous System (CNS) Vital Signs Neurocognitive Test Battery will be used to asesses neurocognitive abilities.

Animated Video and Booklet Education for Improving Asthma Control and Medication Compliance in Children

Asthma is a chronic inflammatory disease that causes wheezing, coughing, and shortness of breath, and it is a significant cause of morbidity and mortality in the pediatric population. The World Health Organization (WHO) estimated that 262 million people were affected by asthma in 2019, with 461,000 asthma-related deaths annually. In Turkey, the prevalence of asthma in children aged 6-12 ranges from 2% to 16%. Inadequate asthma control in children is often associated with poor medication adherence, lack of knowledge, misbeliefs, and ineffective communication with healthcare professionals. Education is therefore a crucial element of successful asthma management. Recently, the use of digital tools such as animated videos has become increasingly popular in pediatric education due to their engaging and interactive nature. Studies have shown that visual and interactive materials can improve knowledge, satisfaction, and adherence in children with chronic illnesses. This randomized controlled study aims to evaluate the effect of an educational intervention using an animated video and booklet on asthma control and medication compliance in children aged 7-11 diagnosed with asthma. It is expected that this child-friendly, visually enriched educational approach will enhance asthma management and support medication adherence in children.
