    Comparison of Biomechanical Behaviour of Maxilla Following Le Fort 1 Osteotomy With 2-Versus 4-Plate Fixation Using 3d-Fea Part 2: Impaction Surgery
    (Churchill Livingstone, 2009) Atac, M. S.; Erkmen, E.; Yucel, E.; Kurt, A.
    The aim of the second part of this Study was to evaluate the mechanical behaviour of 2- versus 4-plate fixation and bony structures after Le Fort I impaction surgeries using three-dimensional finite element analysis (3D-FEA). Two 3D-FEA models were created to fixate the impacted maxilla at the Le Fort I level as 2-plate fixation at the piriform rims (IMP-2 model) and 4-plate fixation at the zygomatic buttresses and piriform rims (IMP-4 model). The IMP-2 model contained 225 664 elements and 48 754 nodes and the IMP-4 model consisted of 245 929 elements and 53 670 nodes. The stresses in each maxillary model were computed. The models were loaded on one side, at the molar-premolar region, in vertical, horizontal and oblique directions to reflect the chewing process. It was concluded that the use of 4-plate fixation following Le Fort I advancement Surgery provides fewer stress fields on the maxillary bones and fixation materials than 2-plate fixation from a mechanical point of view.

    Interprofessional Simulation-Based Training in Gynecologic Oncology Palliative Care for Students in the Healthcare Profession: a Comparative Randomized Controlled Trial
    (Churchill Livingstone, 2020) Uslu-Sahan, Fatma; Terzioglu, Fusun
    Background: Preprofessional palliative care education may be inadequate, leaving a gap in health professional students' knowledge and understanding of managing patients with gynecologic cancer and their families. Interprofessional simulation-based training may be useful in helping health professional students gain the necessary skills required for palliative care. Objective: This study aimed to determine the effectiveness of different simulation methods used for interprofessional training on gynecologic oncology palliative care knowledge, interdisciplinary education perceptions, and teamwork attitudes of health professional students and to compare these methods. Design: A comparative randomized controlled trial was conducted with a pre-test and two post-tests. Settings: This study was conducted at a university in Ankara, Turkey, in 2016-2017. Participants: A convenience sample of 84 interprofessional students (nursing, medical, nutrition-dietician, and social work) was used in the study. Methods: Students were stratified by their profession and randomized by four blocks into high-fidelity simulation, hybrid simulation, and a control group. Data were collected using a semi-structured questionnaire form, palliative care knowledge test, interdisciplinary education perception scale, and teamwork attitudes questionnaire. Results: The high-fidelity simulation and hybrid simulation groups improved their palliative care knowledge, interdisciplinary education perception, and teamwork attitudes from pre-test to first and second post-tests compared to the control group. Conclusion: The introduction of high-fidelity simulation and hybrid simulation or hybrid simulation-based interprofessional training in undergraduate education can increase students' palliative care knowledge, interdisciplinary education perception, and teamwork attitudes. Training programs that are used together with highfidelity simulation and hybrid simulation applications in interdisciplinary training should be integrated into the undergraduate curricula of future cooperating health professions.

    Comparison of Biomechanical Behaviour of Maxilla Following Le Fort I Osteotomy With 2-Versus 4-Plate Fixation Using 3d-Fea. Part 1: Advancement Surgery
    (Churchill Livingstone, 2008) Atac, M. S.; Erkmen, E.; Yucel, E.; Kurt, A.
    The study aimed to calculate the location and intensity of the maximum stress fields on the fixation plates and surrounding maxilla following Le Fort I osteotomies after advancement procedures using three-dimensional finite element analysis. The models were generated using skull CT scan data. Le Fort I osteotomy Simulations were made and two separate impacted maxillary models were designed. The ADV-2 model has 2 plate fixations bilaterally at the piriform rims, the ADV-4 model has 4 plate fixations at the zygomatic buttresses and piriform rims. The stress fields on bone, plate and screws were computed for each model. Posterior occlusal loads were simulated on one side in the molar-premolar region, in all three directions, reflecting the chewing forces. The increased locations of highest Von Mises stresses on the plates and highest maximum principle stresses on the bones were determined in ADV-2 models especially Under horizontal and oblique loads when compared with ADV-4 models. Evaluation of the highest Von Mises Stress Values and maximum principal stress revealed that oblique load in the ADV-2 model received the highest values. 4-plate fixation following Le Fort I advancement Surgery exerts less stress on the maxillary bones and fixation materials than 2-plate fixation.

    Recent Advances in Nanomedicine Development for Traumatic Brain Injury
    (Churchill Livingstone, 2023) Ling, Yating; Ramalingam, Murugan; Lv, Xiaorui; Zeng, Yu; Qiu, Yun; Si, Yu; Hu, Jiabo
    Traumatic brain injury (TBI) is one of the major causes of morbidity and mortality worldwide, and it is also a risk factor for neurodegeneration. However, there has not been perceptible progress in treating acute TBI over the last few years, mainly due to the inability of therapeutic drugs to cross the blood-brain barrier (BBB), failing to exert significant pharmacological effects on the brain parenchyma. Recently, nanomedicines are emerging as a powerful tool for the treatment of TBI where nanoscale materials (also called nanomaterials) are employed to deliver therapeutic agents. The advantages of using nanomaterials as a drug carrier include their high solubility and stability, high carrier capacity, site-specific, improved pharmacokinetics, and biodistribution. Keeping these points in consideration, this article reviews the pathophysiology, current treatment options, and emerging nanomedicine strategies for the treatment of TBI. The review will help readers to gain insight into the state-of-the-art of nanomedicine as a new tool for the treatment of TBI.

    Comparison of biomechanical behaviour of maxilla following Le Fort I osteotomy with 2-versus 4-plate fixation using 3D-FEA Part 3: Inferior and anterior repositioning surgery
    (Churchill Livingstone, 2009) Erkmen, E.; Atac, M. S.; Yucel, E.; Kurt, A.
    Having studied the effect of maxillary advancement and maxillary impaction in parts 1 and 2 of this research, the purpose of this study was to investigate the biomechanical behavior of different fixation models in inferiorly and anteriorly repositioned maxilla following Le Fort I osteotomy. Two separate three-dimensional finite element models, simulating the inferiorly advanced maxilla at Le Fort 1 level, were used to compare 2- and 4-plate fixation. Model INF-2 resulted in 247 897 elements and 53 247 nodes and INF-4 consisted of 273 130 elements and 59 917 nodes. The stresses occurring in and around the bone and plate-screw complex were computed. The highest Von Mises stresses on the plates and maximum principal stresses on the bones were found in INF-2, especially under horizontal and oblique loads, when compared with INF-4. The present biomechanical study shows that the traditionally used 4-plate fixation technique, following Le Fort I inferior and anterior repositioning surgery, Without bone grafting, provides fewer stress fields on the maxillary bones and fixation materials.

    The Role of Emotional Intelligence in the Relationship Between Burnout and Perceived Quality of Care Among Oncology Nurses
    (Churchill Livingstone, 2026) Sarı, T.; Çalışkan, B.B.; Pars, H.; Güner-Küçükkaya, P.
    Purpose This study aimed to examine the relationships between burnout, emotional intelligence, and perceived caring behaviours among oncology nurses and to assess the predictive and mediating roles of these variables in explaining caring behaviours. Methods A descriptive, cross-sectional study was conducted with 202 oncology nurses in Türkiye. Data were collected using validated instruments measuring burnout, emotional intelligence, and caring behaviors. Data analysis employed descriptive statistics, Pearson correlation analyses, multiple linear regression, and structural equation modeling. Results Emotional intelligence was positively associated with caring behaviours (r = .359, p < .001) and negatively associated with burnout subdimensions. Caring behaviours were inversely related to emotional exhaustion (r = −.258, p < .001), depersonalisation (r = −.397, p < .001), and reduced personal accomplishment (r = −.214, p = .002). In the regression model (R2 = .214, p < .001), emotional intelligence significantly predicted caring behaviours positively (β = .218, p = .002), while depersonalisation was a significant negative predictor (β = −.288, p < .001). However, emotional intelligence did not mediate the relationship between burnout and caring behaviours (Sobel test p = .332). Conclusion While emotional intelligence was positively associated with caring behaviours and buffered the impact of burnout—particularly depersonalisation—it did not mediate the relationship between burnout and caring. These findings support the value of enhancing emotional intelligence to improve care quality and nurse well-being, though contextual factors may influence its mediating role. © 2026 Elsevier Ltd.
