Resumen
Este estudio presenta el valor esperado ajustado por pérdidas (LaEV) para recomendar múltiples tratamientos en meta-análisis en red (NMA). LaEV ofrece un sistema de clasificación válido que penaliza la incertidumbre, adecuado para tomadores de decisiones reacios al riesgo.
Área de la Ciencia:
- Economía de la Salud
- Análisis de Decisiones
- Bioestadística
Sus antecedentes:
- El meta-análisis en red (NMA) típicamente recomienda un solo tratamiento basado en el valor esperado (VE) más alto.
- Los métodos existentes pueden no abordar adecuadamente la aversión al riesgo o la incertidumbre del tomador de decisiones.
- Necesidad de sistemas de clasificación que penalicen la incertidumbre e identifiquen opciones de tratamiento clínicamente relevantes.
Objetivo del estudio:
- Desarrollar y evaluar enfoques novedosos para recomendaciones de múltiples tratamientos en NMA.
- Introducir y evaluar el valor esperado ajustado por pérdidas (LaEV) como criterio de decisión reacio al riesgo.
- Comparar LaEV con métodos existentes como GRADE y clasificaciones basadas en probabilidad.
Principales métodos:
- Introducción del valor esperado ajustado por pérdidas (LaEV) y definición de propiedades de clasificación deseables.
- Desarrollo de un proceso de recomendación de dos etapas que incorpora la diferencia mínima clínicamente importante (MCID).
- Análisis comparativo utilizando ejemplos estilizados y 10 NMA del Instituto Nacional de Salud y Cuidado de Excelencia (NICE).
Principales resultados:
- LaEV produce de manera confiable clasificaciones válidas bajo incertidumbre y posee propiedades deseables.
- Las recomendaciones basadas en LaEV fueron más conservadoras que el VE estándar, recomendando menos tratamientos (mediana de 2 menos).
- Las reglas de GRADE mostraron anomalías, a veces sin recomendar el tratamiento con el VE/LaEV más alto y privilegiando opciones inciertas.
Conclusiones:
- LaEV proporciona un método teóricamente sólido, conservador y aplicable para la toma de decisiones reacia al riesgo en NMA.
- Un enfoque de dos etapas que utiliza MCID garantiza un número clínicamente apropiado de tratamientos recomendados.
- LaEV ofrece una alternativa superior al VE estándar, GRADE y las clasificaciones basadas en probabilidad para comparaciones complejas de tratamientos.

02:55Exceptions to the Octet Rule

Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

02:36Lewis Symbols and the Octet Rule
80.9K
Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis developed a model called the Lewis model that simplified the depiction of chemical bond formation and provided straightforward explanations for the chemical bonds seen in most common compounds.

03:02The Aufbau Principle and Hund's Rule
72.8K
To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen, and continuing across the periods of the periodic table, we add one proton at a time to the nucleus and one electron to the proper subshell until we have described the electron configurations of all the elements. This procedure is called the aufbau principle, from the German word aufbau (“to build up”). Each added electron occupies the...

01:14Conditioned Taste Aversion
607
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

02:26Protein Networks
4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:20Decision Making
975
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...
