Öğe Türü:Öğe, Relationship between social skills and addiction in children(Journal Of Behavioral Addictions, Nov 4 2025) Basgul, Saziye Senem; Arslan, Kubra Temiz[Abstract Not Available]Öğe Türü:Öğe, The Effect of Reflective Blankets on Reducing Inadvertent Perioperative Hypothermia in Abdominal Surgery Patients: A Randomized Controlled Trial(W.B. Saunders, 2025) Yava, Ayla; Güzel, Ali; Koyuncu, AynurPurpose: This study aimed to evaluate the effect of a reflective blanket on reducing perioperative hypothermia and on thermal comfort and shivering levels in patients undergoing abdominal surgery. Design: The research is in the design of a randomized controlled clinical trial. Methods: This randomized controlled trial, conducted between February 2022 and January 2023 in a public hospital, included 105 American Society of Anesthesiologists I and II patients undergoing laparoscopic cholecystectomy or umbilical hernia surgery. Patients were randomized into three groups: active warming (n = 35), reflective blanket (n = 35), and routine care (n = 35). The active warming and reflective blanket groups received 15 minutes of prewarming. Body temperature, shivering, and thermal comfort were assessed. Data were analyzed with SPSS 21.0 (IBM Corp) (P < .05). Findings: There were no statistically significant differences between the groups in terms of demographic and clinical characteristics (P > .05). At the end of anesthesia, hypothermia was observed in 71.4% of patients in the control group, 42.9% in the intervention group and 28.6% in the reference group (P < .05). Before clinical transfer, hypothermia persisted only in the control group (37.1%) and was not observed in the other two groups (P < .001). Shivering was seen only in the control and intervention groups, while it was absent in the reference group (P < .05). Thermal comfort scores were similar at baseline, but during the perioperative period, the reference group had the highest and the control group the lowest scores (P < .01). Conclusions: The use of reflective blankets was as effective as active warming in reducing the incidence of inadvertent perioperative hypothermia and shivering and increasing the level of thermal comfort perception in patients and provided superiority over the control group. © 2026 American Society of PeriAnesthesia Nurses.

This study presents a comparative assessment of deep learning (DL) and machine learning (ML) methods in river SSC prediction of two river stations on the Mississippi River, United States. To that end, two single DL models, namely recurrent neural networks (RNN) and bidirectional RNN (BiRNN) were developed. Generally, the RNN was found to outperform the BiRNN for predicting SSC. Furthermore, a convolutional neural network (CNN) was coupled on the applied DL models to create the hybrid RNN-CNN and BiRNN-CNN models. The results denoted that the BiRNN-CNN models generally performed better compared with RNN-CNN ones. Besides the four types of DL models, three forms of ML models, including adaptive boosting (AdaBoost), natural gradient boosting (NGBoost), and gradient boosting regression trees (GBRT) were also established. As a general conclusion, NGBoost and GBRT demonstrated the highest and lowest level of accuracy in river SSC forecasting. Eventually, the influence of input predictors on the outputs of models was done considering local interpretable model-agnostic explanations (LIME). Assessing the LIME outcomes for the selected samples of the test data revealed that the current daily river streamflow and one daily lagged SSC data were the most effective inputs on SSC prediction results.Öğe Türü:Öğe, Relationship between childhood traumas, cognitive distortions and aggression in forensic psychiatry patients aggression in forensic psychiatry patients(Journal Of Forensic Psychiatry & Psychology, Dec 2025) Atay, Eda; Dogan, Ufuk; Isil, Ozlem; Hekim, Buke; Kilic, NiluferAggression is a common problem in forensic psychiatric patients and an important problem for psychiatric nurses during the treatment, care and rehabilitation of patients. The aim of this study is to determine the relationship between childhood traumas, cognitive distortions and aggression in forensic psychiatry patients. This descriptive study was conducted with 103 forensic psychiatry patients treated in a high security forensic psychiatry hospital. The data of study were collected Introductory Information Form, Childhood Psychological Traumas Scale (CTQ), Cognitive Distortions Scale (CDS) and Buss-Perry Aggression Scale (BAQ). The data of the study were collected using the Introductory Information Form, the Childhood Trauma Questionnaire (CTQ), which assesses traumatic experiences in childhood; the Cognitive Distortions Scale (CDS), which measures dysfunctional thought patterns; and the Buss-Perry Aggression Questionnaire (BAQ), which evaluates levels of aggression. The study found a significant positive correlation among childhood traumas, cognitive distortions, and aggression, indicating that higher levels of childhood trauma and cognitive distortions are associated with increased aggression. This study highlights the importance of considering both early traumatic experiences and cognitive processes together in the management and prevention of aggression among forensic psychiatric patients. The findings emphasize the necessity of taking these factors into account for risk assessment and effective treatment planning.Öğe Türü:Öğe, Effects of Dual-Task Stroboscopic Visual Training on Balance, Functional Mobility, and Gait in Children Who Are Hard-of-Hearing: A Exploratory Randomized Controlled Study(Multidisciplinary Digital Publishing Institute (MDPI), December 2025) Usgu, Serkan; Yakut, Yavuz; Gözen, HafizaObjective: This study aimed to investigate the effects of dual-task stroboscopic visual training (DTSVT) on balance, functional mobility, and gait in children who are hard-of-hearing. Methods: This randomized controlled study included 31 children (17 girls, 14 boys) with congenital sensorineural hearing loss. Participants were assigned to one of three groups: control group, conventional balance training (CBT) group, and DTSVT group. The CBT and DTSVT groups participated in an exercise program for 16 weeks, twice weekly, for 40 min (a total of 24 sessions). Static balance was assessed using the Tandem Romberg test and Single-Leg Stance (SLS) test, while dynamic balance was evaluated using the Functional Reach Test (FRT), balance disc test, and the Four Square Step Test (FSST). The Pediatric Balance Scale (PBS) was used as a subjective balance assessment. Functional mobility was assessed using the Timed Up and Go (TUG) Test, Step Test, 10 m Walk Test (10 MWT), and Functional Gait Assessment (FGA). Postural sway parameters were recorded using the GyKo device, including Sway Area (EA, cm2), Distance Length (DL, cm), Length (anterior–posterior (AP)) (cm), Length (medial–lateral (ML)) (cm), Mean Distance (D) (cm), Mean Distance (AP) (cm), and Mean Distance (ML) (cm). Results: Significant between-group differences were primarily observed in favor of the DTSVT group post-treatment, particularly in PBS scores, GyKoDL values during the eyes-open SLS test, and TUG test completion times (p < 0.05). Some baseline differences were noted among groups in functional reach distance, FSST completion time, and eyes-closed duration on the Balance Disc test (p < 0.05). Within-group comparisons revealed significant improvements in FSST times in both intervention groups, reduced postural sway parameters during the FRT in the DTSVT and control groups, and increased eyes-closed Tandem Romberg duration in the CBT group (p < 0.05). Most other outcome measures did not demonstrate statistically significant changes either within or between groups (p > 0.05). Conclusions: Dual-task stroboscopic visual training was more effective than conventional balance training in improving specific aspects of balance and functional mobility in children who are hard-of-hearing. These findings highlight the potential of adding cognitively demanding and visually engaging balance tasks to rehabilitation programs for this population. Larger and more diverse samples in future studies are needed to enhance the generalizability of these results. Studies that assess balance and gait using standardized clinical or laboratory tests may be particularly valuable. Given the small sample size and multiple comparisons, the results should be considered preliminary and exploratory. © 2025 by the authors.
