Resumen
Los sobrevivientes de cáncer que se preparan para las malas noticias experimentan más ansiedad por la exploración, o miedo a la recurrencia, antes de las exploraciones. Este temor disminuye con buenos resultados, pero las estrategias positivas de afrontamiento no reducen la ansiedad.
Área de la Ciencia:
- Psicología
- En el campo de la oncología
- Psicología de la salud
Sus antecedentes:
- La ansiedad por la exploración, o el miedo a la recurrencia del cáncer, es un problema importante que afecta la calidad de vida de los sobrevivientes de cáncer.
- Existe una investigación limitada sobre los factores de riesgo en tiempo real para la ansiedad por la exploración durante la vigilancia del cáncer.
Objetivo del estudio:
- Investigar cómo las estrategias de gestión de la incertidumbre predicen la ansiedad en adolescentes y adultos jóvenes sobrevivientes de cáncer.
- Examinar la experiencia en tiempo real del temor a la recurrencia del cáncer (FCR) en torno a las exploraciones de vigilancia.
Principales métodos:
- Diseño de evaluación momentánea ecológica utilizado con 55 sobrevivientes de cáncer en adolescentes y adultos jóvenes.
- Los sobrevivientes informaron estrategias de manejo de la incertidumbre (abrazar, esperanza, optimismo).
- El FCR diario fue rastreado a través de una aplicación de teléfono inteligente durante 11 días en torno a escaneos de vigilancia.
Principales resultados:
- Se espera el peor pronóstico de mayor FCR antes de las exploraciones y un aumento más pronunciado de la FCR diaria.
- El bracing también se correlacionó con un FCR más alto el día de la exploración y una disminución más rápida después de la exploración con buenos resultados.
- Las estrategias de esperanza y optimismo no predijeron los niveles diarios de FCR.
Conclusiones:
- La ansiedad por las malas noticias puede intensificar la ansiedad de los supervivientes de cáncer que esperan las exploraciones.
- Las estrategias positivas de afrontamiento como la esperanza y el optimismo no mitigaron la ansiedad.
- Los hallazgos ofrecen ideas para desarrollar intervenciones para controlar la ansiedad por la exploración.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
167
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
