Relação entre satisfação por compaixão, burnout e estresse traumático com a segurança do paciente / Relación entre satisfacción por compasión, burnout y estrés traumático con la seguridad del paciente / Relationship among compassion satisfaction, burnout and traumatic stress with the patient safety

Objective: to analyze the relationship among compassion satisfaction, burnout, and secondary traumatic stress with the patient safety culture. Method: cross-sectional study with nurses (n = 201) from hospitals in Portugal. The Professional quality scale and the three sections of Hospital survey on patient safety culture were used to data collection. Correlation and regressions tests were implemented. Results: compassion satisfaction was positively related to four of the five patient safety culture dimensions and with the patient safety grade, while burnout had a negative relationship with all the dimensions and with the patient safety grade and secondary traumatic stress had a negative relationship with three patient safety culture dimensions. Conclusions: measures aimed at increasing compassion satisfaction and decreasing burnout and secondary traumatic stress should be implemented to improve the quality of professional life and patient safety.(AU)

Objetivo: analizar la relación entre satisfacción por compasión, burnout y estrés traumático secundario con la cultura de seguridad del paciente. Método: estudio transversal con enfermeras (n = 201) de hospitales de Portugal. Para la recopilación de datos se utilizaron la Professional quality scale y tres secciones de la Hospital survey on patient safety culture. Se implementaron pruebas de correlación y regresión. Resultados: la satisfacción por compasión se relacionó positivamente con cuatro de las cinco dimensiones de cultura de seguridad del paciente y con el grado de seguridad, mientras que burnout tuvo una relación negativa con todas las dimensiones y con el grado de seguridad y estrés traumático secundario tuvo una relación negativa con tres dimensiones. Conclusiones: se deben implementar medidas destinadas a aumentar la satisfacción por compasión y disminuir el burnout y el estrés traumático secundario para mejorar la calidad de vida profesional y la seguridad del paciente.(AU)

Effects of thermal and mechanical fatigue stress on bond strength in bracket base configurations / 대한치과교정학회지

The purpose of this study is to evaluate the effects of mechanical and thermal fatigue stress on the shear, tensile and shear-tensile combined bond strengths(SBS, TBS, CBS) in various orthodontic brackets bonded to human premolars with chemically cured adhesive(Ortho-one, Bisco, USA). Five types of commercially available metal brackets with various bracket base configurations of Photoetched base(Tomy, Japan), Non-Etched Foil Mesh base(Dentaurum, Germany), Micro-Etched Foil Mesh base(Ortho Organizers, USA), Chessboard base(Daesung, Korea), and Integral base(3M Unitek, USA) were used. Samples were divided into 3 groups, the first group was acted with shear-tensile combined loads(45 degrees) of 200g for 4 weeks(mechanical fatigue stress), the second group was subjected to the 5,000 thermocycles of 15 second dwell time each in 5 degrees C and 55 degrees C baths(thermal fatigue stress), and the third group was the control. Bond strengths were measured at the crosshead speed of 0.5 mm/min. The cross-section of bracket base/adhesive interface and the fracture surface were examined with the stereoscope and the scanning electron microscope. The resin remnant on bracket base surface was assessed by ARI(Adhesive Remnant Index). The obtained results were summarized as follows; 1. In static bond strength, Photoetched base bracket showed the maximum bond strength and Integral base bracket showed the minimum bond strength(p<0.05). In all brackets, shear bond strength(SBS) was in the greatest value and shear-tensile combined strength(CBS) was in the least value(p<0.05). 2. After mechanical fatigue test, Photoetched base bracket showed the maximum bond strength and Integral base bracket showed the minimum bond strength(p<0.05). In Photoetched base bracket and Micro-Etched Foil Mesh base bracket, shear bond strength(SBS), tensile bond strength(TBS) and shear-tensile combined strength(CBS) were decreased after mechanical fatigue test(p<0.05). 3. After thermocycling, Integral base bracket showed the minimum bond strength. The SBS, TBS and CBS of Photoetched base, Chessboard base, and Micro-Etched Foil Mesh base bracket were decreased after 5,000 cycled thermocycling(p<0.05). 4. In static test, bond failure sites were mainly between bracket and adhesive. After thermocycling, ARI scores were greater than those in static test. 5. SEM micrographs of cross-section of bracket bonding site showed that many micro-cracks in bracket/resin interface and in enamel/resin interface were found in all brackets after thermocycling.
