Resumen
Los nuevos biomarcadores sanguíneos pueden evaluar objetivamente la gravedad del dolor crónico en pacientes psiquiátricos. Los principales marcadores CD55 y ANXA1, relacionados con la inflamación y el dolor, sugieren tratamientos personalizados como el litio y la ketamina.
Área de la Ciencia:
- Neurociencia y Genética
- Descubrimiento de biomarcadores
- Investigaciones psiquiátricas
Sus antecedentes:
- El dolor crónico afecta significativamente a las poblaciones de salud general y mental, con vínculos bidireccionales.
- No existen herramientas objetivas para evaluar el dolor, lo que dificulta el tratamiento y la prevención eficaces.
- Los biomarcadores sanguíneos ofrecen una ventana potencial a la biología del dolor, ayudando a la evaluación y el tratamiento.
Objetivo del estudio:
- Para identificar, priorizar y validar los biomarcadores de expresión génica de la sangre para el dolor.
- Para investigar estos biomarcadores trans-diagnóstico en pacientes psiquiátricos.
- Establecer biomarcadores reproducibles utilizando múltiples cohortes y plataformas independientes.
Principales métodos:
- Se llevaron a cabo dos estudios independientes utilizando microarrays y secuenciación de ARN.
- Empleado un diseño de cohortes múltiples independientes para la reproducibilidad biológica y técnica.
- Centrado en biomarcadores convergentes y reproducibles entre los dos estudios.
Principales resultados:
- Identificaron biomarcadores nuevos y conocidos que predicen estados de dolor intenso y futuras visitas al departamento de emergencias.
- El biomarcador con mayor disminución de expresión (supresor del dolor) fue CD55; el biomarcador con mayor aumento (algógeno) fue ANXA1.
- Las vías clave involucraron la respuesta celular al TNF y la neuroinflamación, con el TNF como el regulador superior.
Conclusiones:
- CD55 y ANXA1 validados como biomarcadores sanguíneos clave para la evaluación del dolor crónico en pacientes psiquiátricos.
- Se identificaron posibles combinaciones terapéuticas que incluyen litio, ketamina, ácidos grasos omega-3 y magnesio.
- Desarrolló un marco para informes personalizados de pacientes para ayudar a la evaluación objetiva y la combinación de tratamientos individualizados.

01:25Analgesia and Pain Management
788
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

02:50Combination Therapies and Personalized Medicine
5.1K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

01:15Opioid Analgesics: Synthetic and Semisynthetic Opioids
426
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

01:44Nociception
29.4K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

01:20Pain
631
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

01:20Opioid Analgesics: Morphine and Other Natural Cogeners
361
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...
