Simulations of Multifocal Vision in Patients With Previous Monofocal Intraocular Lens Implantation.

PURPOSE: To evaluate the effectiveness and patient acceptance of multifocal vision simulation in patients with previous monofocal intraocular lens (IOL) implantation, and to explore their willingness-to-pay (WTP) and willingness-to-accept (WTA) based on the perceived advantages and disadvantages of multifocal vision. METHODS: Seventeen patients with previous monofocal IOL implantation participated in this cross-sectional study. The SimVis Gekko device (2EyesVision SL) was used to simulate monofocal (Evaluation B) and multifocal (Evaluation C) visual experiences, compared to their existing vision (Evaluation A). Visual acuity at three distances and defocus curves were measured. Patients responded to inquiries about visual quality in each evaluation, bothersomeness of photic phenomena, probability to select the visual experience, and the monetary value they associated with enhanced WTP or diminished WTA visual quality. RESULTS: The simulations underestimated the visual acuity reported for the IOL in existing literature by one or two lines, depending on the testing distance. This underestimation was more pronounced in defocus curves. However, 70.6% of patients were likely or very likely to opt for multifocal vision, indicating they perceived the benefits of multifocality. The WTP for multifocal vision was twice that of monofocal vision, and the WTP/WTA ratio exceeded 1, suggesting the perceived vision benefits outweighed potential drawbacks. CONCLUSIONS: Despite underestimating the expected postoperative visual performance, the multifocal simulation enabled patients to perceive the benefits of multifocal vision to some extent. This system could be beneficial in avoiding potential postoperative complaints, but the possible rise in false-positive results should be considered and evaluated in future research.

Análisis de la evolución de los operados mediante cirugía de mínimo acceso en nuestro hospital. ¿Presenta mejores resultados que la convencional? / Analysis of the evolution of those operated on with minimal access surgery in our hospital. Does it present better results than the conventional one?

Resumen La estenosis aórtica severa sintomática es la patología quirúrgica más prevalente en cirugía cardiaca y su sustitución aislada se ha realizado históricamente mediante esternotomía media completa. Sin embargo, se ha producido recientemente una gran revolución, especialmente tras la llegada de las prótesis aórticas sin suturas que, unido a un nuevo impulso por la cirugía cardiaca hacia un rumbo menos invasivo, ha provocado que el reemplazo de dicha válvula se lleve a cabo cada vez más frecuentemente por dichas prótesis y por incisiones de mínimo acceso. Por ello, realizamos una revisión de los casos intervenidos en nuestro servicio desde el inicio del programa de cirugía de mínimo acceso comparándolos con los resultados de los casos intervenidos en la misma época mediante cirugía convencional.

Abstract Symptomatic severe aortic stenosis is the most prevalent surgical pathology in cardiac surgery, and its isolated replacement has historically been performed by means of complete middle sternotomy. However, a great revolution has recently taken place, especially after the arrival of sutureless aortic prostheses that, together with a new impulse by cardiac surgery towards a less invasive course, has caused the replacement of said valve to be carried out more and more frequently due to these prostheses and minor access incisions. For this reason, we carried out a review of the cases operated on in our service from the beginning of the minimum access surgery program, comparing them with the results of the cases operated at the same time using conventional surgery.

Factors that Influence Treatment Delay for Patients with Breast Cancer.

INTRODUCTION: The diagnosis or treatment of breast cancer is sometimes delayed. A lengthy delay may have a negative psychological impact on patients. The aim of our study was to evaluate the sociodemographic, clinical and pathological factors associated with delay in the provision of surgical treatment for localised breast cancer, in a prospective cohort of patients. METHODS: This observational, prospective, multicentre study was conducted in ten hospitals belonging to the Spanish national public health system, located in four Autonomous Communities (regions). The study included 1236 patients, diagnosed through a screening programme or found to be symptomatic, between April 2013 and May 2015. The study variables analysed included each patient's personal history, care situation, tumour history and data on the surgical intervention, pathological anatomy, hospital admission and follow-up. Treatment delay was defined as more than 30 days elapsed between biopsy and surgery. RESULTS: Over half of the study population experienced surgical treatment delay. This delay was greater for patients with no formal education and among widows, persons not requiring assistance for usual activities, those experiencing anxiety or depression, those who had a high BMI or an above-average number of comorbidities, those who were symptomatic, who did not receive NMR spectroscopy, who presented a histology other than infiltrating ductal carcinoma or who had poorly differentiated carcinomas. CONCLUSIONS: Certain sociodemographic and clinical variables are associated with surgical treatment delay. This study identifies factors that influence surgical delays, highlighting the importance of preventing these factors and of raising awareness among the population at risk and among health personnel.

Síndrome de Burnout en el personal profesional del Hospital de Yumbel / Burnout syndrome in staff of the Yumbel Hospital

Objetivos Determinar la prevalencia del Síndrome de Burnout en el personal profesional del Hospital Yumbel. Relacionar presencia del Síndrome de Burnout con variables sociodemográficas. Determinar presencia de los síntomas más frecuentes que denotan tendencia a padecer Burnout. Métodos: Estudio transversal, descriptivo. Aplicación encuesta Maslach Burnout Inventory (MBI) a la totalidad de profesionales médicos (6) y no médicos (16), correspondiendo a 15 mujeres y 7 hombres, funcionarios, pertenecientes al Hospital Yumbel, en Octubre 2004. Organización resultados en tablas de distribuciones de frecuencias y de asociación. Resultados: Edad promedio fue 37 años. Hubo 59,1 por ciento de profesionales casados (4 separados). 14 tenían menos de 10 años de profesión, 2 entre 10 y 20 años y 6 más de 20 años de ejercicio profesional. No hubo Burnout; sí, tendencia en 22,7 por ciento. Hubo 59,1 por ciento de cansancio al final de la jornada, 40,9 por ciento fatiga al levantarse por la mañana y 31,8 por ciento creía estar trabajando demasiado, todos más frecuentes en mujeres. Perfil sociodemográfico más cercano al diagnóstico de tendencia a tener Burnout fue: Sexo femenino, edad entre 24-40 años, soltera y ejercicio profesional menor a 10 años. Conclusiones: Los resultados no evidenciaron presencia de Burnout; hubo tendencia a desarrollarlo en porcentaje no despreciable, presentando un patrón sociodemográfico definido y similar a estudios de la literatura.
