The Effect of Preoperative Hugging With Family Members on Preoperative Anxiety Levels and Postoperative Pain

The aim of this randomized prospective study is to examine the effect of preoperative family hugging (for at least 20 seconds) on preoperative anxiety levels and postoperative pain. The main question the study aims to answer is: * Does preoperative hugging reduce anxiety levels? * Does preoperative hugging reduce postoperative pain scores? Anxiety and pain scores will be evaluated between patients who hugged and those who did not hug their family members before surgery, and whether hugging has an effect will be assessed.

The Effect of Using the Popit Toy and Stress Ball During Inhaler Therapy in Children

The goal of this clinical trial is to evaluate whether using a popit toy and a stress ball as distraction methods during inhaled medication administration can reduce anxiety, fear, and negative emotional responses and improve satisfaction in children aged 4-6 years receiving treatment in a pediatric emergency unit. The main questions it aims to answer are: * Does using a popit toy or a stress ball during inhaled medication administration reduce children's anxiety, fear, and negative emotional responses? * Does using a popit toy or a stress ball improve children's satisfaction with the procedure? * Do these distraction methods affect physiological parameters? To determine the effects of these non-pharmacological methods, researchers will compare the Popit toy group, the stress ball group, and the standard control group, which receives no intervention. Researchers compared a pop-it toy group, a stress ball group, and a control group to determine the effects of these non-pharmacological methods. Participants: * Participants were randomly assigned to one of three groups: the pop-it toy group, the stress ball group, or the control group. * They received inhalation therapy according to the standard treatment protocol. * Assessments of anxiety, fear, emotional state, and satisfaction were conducted before and/or after the procedure. * Physiological parameters (heart rate, respiratory rate, oxygen saturation, and body temperature) were measured before and after the administration of the inhalation medication.

Applied Research on a Non-pharmacological Intervention Program for Older Adults With Subjective Cognitive Decline

This study aims to verify the short-term and long-term effects of a group-based non-pharmacological intervention program for community-dwelling older adults with subjective cognitive decline, and to evaluate its implementation outcomes, through a rigorously designed cluster randomized controlled trial.

Effects of White Noise and Lullaby on Vital Signs of Term Newborns in Neonatal Intensive Care

This clinical study aims to evaluate how two types of gentle sounds - white noise and a traditional Turkish lullaby ("Dandini Dandini Dastana") - affect the vital signs of term newborns cared for in the Neonatal Intensive Care Unit (NICU). The first weeks of life are critical for newborns, especially those who need special care in the NICU. During this time, maintaining physiological stability-such as normal heart rate, breathing rate, and oxygen levels-is essential. In addition to medical treatments, non-pharmacological interventions like music and soothing sounds are increasingly used to reduce stress and support comfort. In this randomized controlled study, 70 term newborns (born after 37 weeks of gestation and weighing at least 2500 grams) were randomly assigned to one of two groups: * White Noise Group: infants listened to a digitally recorded white noise (imitating intrauterine sound patterns) for 20 minutes. * Lullaby Group: infants listened to a recording of the traditional lullaby "Dandini Dandini Dastana" for the same duration. Both interventions were administered three times a day for four consecutive days in a calm NICU environment. The sound level was carefully calibrated not to exceed 55 decibels (dBA), ensuring safety for newborn hearing. Researchers measured heart rate, respiratory rate, and oxygen saturation (SpO₂) at baseline and at the 5th, 10th, 15th, and 20th minutes during each session. Results showed that both white noise and lullaby sessions led to a gradual decrease in heart rate, while breathing rate and oxygen levels remained stable. No adverse events or signs of physiological instability were observed. These findings suggest that both white noise and lullaby listening are safe, low-cost, and effective supportive methods for helping term newborns remain calm and physiologically stable during intensive care. The study contributes to growing evidence that structured auditory stimulation can help promote comfort and self-regulation in newborns without the need for medication.

The Effects of Lemon Essential Oil Inhalation on Attention in Children With Attention Deficit Hyperactivity Disorder (ADHD)

This randomized, placebo-controlled clinical trial aims to evaluate the acute effects of lemon essential oil inhalation on sustained attention and visual memory in children diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). Fifty-two medication-naive children aged 9-16 were randomized to receive either lemon oil or placebo inhalation before cognitive assessments. Primary outcome was sustained attention performance. The study found significant improvements in attention scores in the lemon oil group.

Effect Of Game-Based Breathing Exercise On Pain, Fear, And Anxiety In Children During Venipuncture

Venipuncture is one of the most common invasive procedures in children and is often associated with significant pain, fear, and anxiety.This randomized controlled study will aim to evaluate the effects of a video game-based breathing exercise intervention on pain, fear, and anxiety levels in children aged 7-12 years undergoing routine venipuncture. While the intervention group will receive a video game-based breathing exercise using the BREATHING+ system in addition to standard care, the control group will receive routine venipuncture procedures only. The study population will consist of children aged 7-12 years who meet the inclusion criteria and whose parents/legal guardians provide informed consent. Participants will be randomly assigned to intervention and control groups. Pain, fear, and anxiety levels will be assessed at three time points: before the procedure, during the procedure, and immediately after the procedure. Data will be collected using the Visual Analog Scale (VAS), Children's Anxiety Scale-State (CAS-S), and Children's Fear Scale (CFS), along with a structured questionnaire form. All assessments will be conducted at the predefined time points.

Music Effects on Dementia

Older adults constitute a population whose age-related physiological and cognitive changes predispose them to conditions that are less likely to occur in younger individuals. Dementia encompasses a group of health conditions that primarily affect this age group. These disorders commonly impair mental functions-particularly memory-but they also manifest through behavioral symptoms, such as irritability, and exert a significant impact not only on the affected individual but also on their immediate environment. In this study, the investigators will implement a structured musical improvisation intervention led by four professional concert musicians. This approach, which has demonstrated effectiveness in other populations, aims to evaluate its effects on the mental and physical health of older adults living with dementia. Additionally, the intervention will be assessed in terms of its potential impact on primary caregivers, thereby exploring its reach beyond the individual diagnosed with dementia. Previous studies have reported the effectiveness of such interventions, noting improvements in memory, behavioral symptoms, and even overall physical well-being. To date, no studies of this nature have been conducted in our country, making this the first to pursue an extensive exploration of outcomes-not only those traditionally assessed in similar trials, but also a broader evaluation of various dimensions of health in older adults undergoing the intervention. Additionally, caregivers may also benefit from actively participating in these sessions, which are designed to include them from the very beginning. Beyond generating data on the potential effects across different bodily and cognitive functions-knowledge that may become a leading reference in this field-this intervention holds the potential to be scaled up, thereby benefiting a larger population and ultimately enhancing the care provided to older adults living with dementia.

VR-PMR for Post-Burn Symptoms

The goal of this clinical trial is to learn whether progressive muscle relaxation (PMR), delivered either alone or enhanced with virtual reality (VR), can help treat chronic symptom, such as pain, itch, anxiety, sleep disturbances, and fatigue, in adult burn survivors. The main questions it aims to answer are: * Does VR-enhanced PMR (VR-PMR) reduce chronic pain, anxiety, itch, sleep disturbances, and fatigue more effectively than standard PMR? * Is VR-PMR a feasible and acceptable self-administered home-based intervention for burn survivors? Researchers will compare two self-administered intervention conditions, VR-enhanced PMR and standard PMR, using a randomized to sequence crossover design to see if VR technology enhances the therapeutic effects of PMR on chronic symptom management in burn survivors. Participants will: * Complete home-based sessions of VR-enhanced PMR * Complete home-based sessions of standard PMR * Report symptoms such as pain, itch, anxiety, sleep disturbances, and fatigue throughout the study * Use VR equipment provided for the intervention period (during the VR-PMR arm)
