Un modelo predictivo para la disfunción olfativa en pacientes sometidos a hemodiálisis de mantenimiento
Clinical nephrology
|August 20, 2025
Resumen
La disfunción olfativa afecta al 76,1% de los pacientes en hemodiálisis de mantenimiento (MHD), siendo la edad, el nivel bajo de albúmina, el colesterol bajo y el nivel de educación los factores de riesgo clave para la anosmia. Estos factores también contribuyen al empeoramiento de la función olfativa en pacientes con MHD.
Área de la Ciencia:
- Nefrología
- Otorrinolaringología
- Química clínica
Sus antecedentes:
- La disfunción olfativa es una complicación común en pacientes sometidos a hemodiálisis de mantenimiento (MHD).
- Comprender la prevalencia y los factores de riesgo es crucial para la detección y la gestión tempranas.
Objetivo del estudio:
- Para determinar la prevalencia de la disfunción olfativa en pacientes con MHD.
- Identificar los factores de riesgo asociados con la disfunción olfativa (hiposmia y anosmia).
- Desarrollar y evaluar un modelo predictivo para la anosmia en pacientes con MHD.
Principales métodos:
- Estudio transversal comparando pacientes con MHD con un grupo de control sano.
- Función olfativa evaluada mediante el ensayo Sniffin' Sticks.
- Análisis de regresión logística para identificar los factores de riesgo y construir un modelo predictivo para la anosmia.
Principales resultados:
- La prevalencia de la disfunción olfativa fue significativamente mayor en los pacientes con MHD (76,1%) en comparación con los controles (37,8%).
- La edad avanzada, la hipoalbuminemia, la hipocolesterolemia y el bajo nivel educativo se identificaron como factores de riesgo significativos para la anosmia.
- La hipocolesterolemia también fue un factor de riesgo para la hiposmia.
Conclusiones:
- Existe una alta prevalencia de disfunción olfativa en pacientes con MHD.
- Los factores predictivos para la anosmia incluyen la edad, la hipoalbuminemia, la hipocolesterolemia y el nivel de educación.
- El modelo de predicción desarrollado demostró un buen rendimiento en la evaluación del riesgo de anosmia.

Hemodialysis III: Nursing Management
183
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Olfactory Receptors: Location and Structure
9.6K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Peritoneal Dialysis III: Nursing Management

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Renal Failure: Dose Adjustments
153
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.

Olfaction
45.1K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
