Development of an empathy scale in nurses
(BioMed Central (BMC), 2024) Karaman, Funda; Saygın Şahin, Buse; Yerebakan Şen, Ayşe Nur; Rashidi, Mahruk; Şen Yılmaz, Melis; Kocadereli, Ayşegül; Ustaoğlu, Aleyna
Objective To develop an empathy scale to measure the empathy in nurses. Materials and methods The sample of the study were collected between March and May in 2023 from 720 nurses working in private and state hospitals in İstanbul. Both exploratory factor analysis and confirmatory factor analysis were carried out. IBM SPSS and AMOS were utilized for statistical analyses. Results KMO and Bartlett’s test values of scale showed that the dataset was convenient for factor analyses (KMO=0.94, Chi-Square=9683.89, df=595). In exploratory factor analysis, the 16 items comprising scale were distributed in three subscales. The confirmatory factor analysis revealed that the scale was in sufficient model fit. Cronbach’s alpha of the total scale was 0.91. Conclusion Empathy scale is a valid and reliable measurement tool to evaluate the empathy levels of nurses in three subscales: Emotional Empathy, Cognitive Empathy and Compassionate Empathy. The scale is a valuable tool for quality nursing care and contributes to the definition of strategies that advance the quality of nursing care.
Thermoelastic buckling of FGM conical shells under non-linear temperature rise in the framework of the shear deformation theory
(Elsevier Ltd, 2017) Sofiyev, A.H.; Zerin, Zihni; Kuruoğlu, Nuri
In this study, the thermoelastic buckling of functionally graded material (FGM) conical shells under nonlinear temperature rise across the thickness in the framework of the shear deformation theory (SDT) is investigated. To the derivation of basic equations is used modified Donnell-type shell theory. The Galerkin method is used to obtain the formula for non-linear buckling temperature difference of freely supported FGM truncated conical shell in the framework of the SDT. By changing the properties of FGMs and volume fraction index, the effect of transverse shear deformations on the non-linear buckling temperature difference is evaluated by comparing with the results of the classical shell theory (CST). Meanwhile, the effect of geometric parameters on the non-linear buckling temperature difference of the shear deformable FGM conical shells is discussed in detail.
A Case Report of Volar Dislocation of Ulnar Head: A Very Rare Wrist Injury Easy to Overlook and Easy to Diagnose
(Indian Orthopaedic Research Group (IORG), 2021) Kaya, Özcan; Özkunt, Okan; Kurt, İrem
Introduction: Ulnar volar dislocation (UVD) is a very rare entity. Due to rarity of condition, usually, it’s misdiagnosed at emergency departments and management of this clinical entity is not well studied. Here, we report a case of UVD impressing diagnostic challenge, indication of treatment, and follow-up. Case Report:A 29-year-old man presented to orthopedic outpatient service with complaining of the right wrist pain. He had an assault history 3 days before. In the emergency department, he had been diagnosed as wrist sprain. Splint and pain killers were prescribed. Due to increase of pain, he admitted to orthopedics. He was diagnosed UVD. Under general anesthesia, joint was reduced with forced pronation maneuver. After 3 weeks immobilization period, magnetic resonance images revealed partial injury of triangular fibrocartilage complex then splint removed and rehabilitation initiated. Over than 24 months, he is doing well without movement limitation and wrist strength impairment. Conclusion: For prevention misdiagnosis of UVD, physical examination is very important. Forearm rotation limitation with pain in the wrist should be indicative for distal radioulnar joint injury. Physical examination should be supported with proper evaluation of suitable radiographs. After reduction of joint, magnetic resonance images give clues about ligamentous injury. Our case supports the importance of rigorous physical examination and evaluation of radiographs for wrist injury. In the presence of partial injury of ligaments, the condition can be treated with shorter periods of immobilization and early rehabilitation.
Spontaneous Regression of Herniated Lumbar Disc with New Disc Protrusion in the Adjacent Level
(Hindawi Publishing Corporation, 2016) Hakan, Tayfun; Gürcan, Serkan
Spontaneous regression of herniated lumbar discs was reported occasionally. The mechanisms proposed for regression of disc herniation are still incomplete. This paper describes and discusses a case of spontaneous regression of herniated lumbar discs with a new disc protrusion in the adjacent level. A 41-year-old man was admitted with radiating pain and numbness in the left lower extremity with a left posterolateral disc extrusion at L5-S1 level. He was admitted to hospital with low back pain due to disc herniation caudally immigrating at L4-5 level three years ago. He refused the surgical intervention that was offered and was treated conservatively at that time. He had no neurological deficit and a history of spontaneous regression of the extruded lumbar disc; so, a conservative therapy, including bed rest, physical therapy, nonsteroidal anti-inflammatory drugs, and analgesics, was advised. In conclusion, herniated lumbar disc fragments may regress spontaneously. Reports are prone to advise conservative treatment for extruded or sequestrated lumbar disc herniations. However, these patients should be followed up closely; new herniation at adjacent/different level may occur. Furthermore, it is important to know which herniated disk should be removed and which should be treated conservatively, because disc herniation may cause serious complications as muscle weakness and cauda equine syndrome.
