Resumen
Los chatbots de inteligencia artificial (IA) generativa proporcionan respuestas variadas sobre los nódulos suprarrenales. Si bien las respuestas más precisas contenían jerga, todo el contenido del chatbot superaba los niveles de lectura recomendados para pacientes.
Área de la Ciencia:
- Informática Médica
- Inteligencia Artificial en la Atención Sanitaria
- Endocrinología
Sus antecedentes:
- Los pacientes dependen cada vez más de los chatbots de IA generativa para obtener información médica.
- La precisión, fiabilidad y legibilidad de estas respuestas de IA para afecciones médicas específicas no se comprenden bien.
Objetivo del estudio:
- Evaluar la precisión, fiabilidad y legibilidad percibidas por los cirujanos de las respuestas de los chatbots a las consultas sobre nódulos suprarrenales.
- Comparar el rendimiento de diferentes chatbots de IA en la provisión de información médica.
Principales métodos:
- Se consultó a cinco chatbots populares con seis preguntas comunes sobre nódulos suprarrenales.
- Diez cirujanos endocrinos revisaron y calificaron a ciegas la corrección, fiabilidad y estructura de las respuestas generadas por el chatbot.
- Se utilizaron análisis estadísticos, incluidos ANOVA y correlación intraclase, para evaluar las diferencias y la fiabilidad entre evaluadores.
- Los niveles de lectura se determinaron utilizando el Analizador de Texto Lexile.
Principales resultados:
- Se observaron diferencias significativas en la corrección, fiabilidad y uso de jerga entre los chatbots (p ≤ 0,05).
- Un chatbot (Perplexity) obtuvo la puntuación más alta en corrección, fiabilidad y exhaustividad, pero utilizó la mayor cantidad de jerga.
- Otro chatbot (Gemini) obtuvo la puntuación más baja en todos los dominios, pero utilizó la menor cantidad de jerga.
- El nivel de lectura promedio de las respuestas, medido por Lexile, se situó entre el 8º y el 10º grado.
Conclusiones:
- La información generada por chatbot sobre nódulos suprarrenales presenta una variabilidad significativa en la calidad.
- Las respuestas precisas y fiables a menudo contenían jerga médica excesiva.
- Todas las respuestas de los chatbots superaron los niveles de lectura recomendados para la educación del paciente, lo que podría dificultar la comprensión del paciente.

01:27Adrenal Gland Disorders
3.4K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

01:17Anatomy of the Adrenal Glands
5.0K
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

01:27Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
3.1K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

01:37Hypothalamic-Pituitary Axis
66.8K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

01:22Target Cell Response to Hormones
5.8K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
