Dieta Mediterránea parte de la solución al ASMA en niños
- Consumir muchos 'snacks' salados y dulces eleva casi 5 veces el riesgo de asma.
- También ocurre con los que ven mucha tele o juegan mucho con la videoconsola.
- El asma afecta a 300 millones de personas.
Hay que informar a padres, tutores y maestros de la importancia de llevar un estilo de vida saludable"Así se desprende de un estudio realizado por un grupo de investigadores de la Universidad de Atenas, que examinaron a700 niños con edades comprendidas entre los diez y los doce años, concluyendo que aquellos que no seguían esta dieta y consumían además 'snacks' salados y dulces más de tres veces por semana, tenían un riesgo 4,8 veces mayor de padecer síntomas de asma.
Llevar una vida saludable desde niño
"Teniendo en cuenta que la presencia del asma es muy alta y que ha aumentado mucho en los últimos años, los profesionales de la salud deben informar a padres, tutores, y maestros de la importancia de llevar un estilo de vida saludable, desde las primeras etapas de la vida", explica uno de los autores del estudio, Demosthenes Panagiotakos.
Cien millones más en 2025
En esta línea, otro estudio de la Universidad de Aberdeen (Reino Unido) ha revelado los tresfactores dietéticos responsables del aumento de pacientes de asma, una ingesta de antioxidantes cambiante, un consumo cada vez mayor de ácidos grasos poliinsaturados (AGPI) y el cambio en los niveles de vitamina D consumidos.

Nerve Block Shows Promise for Long COVID-Related Olfactory or Gustatory Dysfunction Patients report improved sense of smell and taste. El bloqueo nervioso es prometedor para la disfunción olfativa o gustativa prolongada relacionada con la COVID Los pacientes informan una mejora en el sentido del olfato y el gusto.
Loss of smell and taste are among the most common symptoms after COVID-19 infection. While a survey published in the International Forum of Allergy & Rhinology indicates that nearly half of those who report olfactory dysfunction regain their sense of smell within a month, the problem can linger.
“I am still seeing patients who had the initial infection in 2020, and for the last three years they have been silently suffering from altered smell and/or taste,” says Christina Shin, MD, a Cleveland Clinic pain management physician.
Olfactory and gustatory training is the first-line recommended treatment. But when it fails, patients are increasingly turning to Dr. Shin and other pain management physicians for a novel treatment – stellate ganglion block (SGB).
Subjective evidence of symptom improvement
In the past year, Dr. Shin has administered the stellate ganglion block with ultrasound imaging guidance to approximately 40 patients. Her first patient arrived to the initial consultation with a case series published by Luke Liu, MD, a pain medicine specialist in Anchorage, Alaska, who pioneered the use of SGB to reduce symptoms in patients with long COVID.
“I don’t tout this as a cure,” says Dr. Shin. “In review of my clinical experience caring for patients, I would conservatively estimate that at least 50% of patients achieve at least 50% improvement. Of course, further research is needed.”
One year after her stellate ganglion block, Dr. Shin’s first patient reports a 90% improvement. That has had a tremendous impact on her quality of life, given that for two years food tasted rancid.
“She is back to work, spending time with family and enjoying her social life,” says Dr. Shin. “She is also off anti-depressants.”
SGB and long COVID theories
Stellate ganglion block targets the sympathetic system, specifically the face and upper extremities. Indications include complex regional pain syndrome of the head and upper limbs, postherpetic neuralgia, hyperhidrosis, chronic post-surgical pain, peripheral vascular disease, and orofacial pain.
It’s unclear how SGB works for patients with loss of smell and taste – or even what causes long COVID – but experts posit several theories.
First, long COVID: One theory is that the virus directly invades tissues in the lungs, nasal mucosa and brain, causing destruction. Another is that the immune system becomes hyperactive in response to the infection, leaving patients in a state of persistent inflammation. A third hypothesis suggests that the sympathetic system is in overdrive, persistently active, leading to fatigue and other long COVID symptoms.
“The fact that the stellate ganglion block is working for some patients tells us that at least for those patients, it may be related to the persistent, overactive sympathetic system,” says Dr. Shin. “So, when we temporarily stop activity at that bundle of nerves and patients get better, perhaps we are interrupting this overactivity and allowing their bodies to reset and get back to a more normal sympathetic balance.”
Another possibility is that the stellate ganglion and the sympathetic system are closely connected to the immune system.
“The thought is that by modulating or blocking the sympathetic system, we somehow regulate the immune system,” says Dr. Shin.
Finally, when the stellate ganglion is blocked, blood flow increases to that side of the body and the brain. That may improve signaling of existing neurons involved in the processing of smell and taste.
Indications, contraindications and risks
Jijun Xu, MD, PhD, who holds joint appointments in Cleveland Clinic’s Department of Pain Management and the Department of Inflammation and Immunity at Lerner Research Institute, also has administered stellate ganglion blocks. Although SGB is a well-defined treatment in pain management, he stresses that its use for olfactory disorder associated with COVID-19 is still experimental and not effective for all patients. However, he considers it a viable option for some patients.
“When SGB works, it seems to work effectively,” says Dr. Xu. “Considering its low risk profile and potential benefit, SGB is worth trying for these patients as it may significantly help improve a patient’s quality of life. More importantly, some patients lose their ability to smell gas in heating appliances or cooking equipment, which could be dangerous or even life-threatening. To bring their smell back is therefore of the utmost importance.”
Patients may require follow-up treatments similar to SGB use for pain management.
At Cleveland Clinic’s reCOVer Clinic for long COVID patients, Dr. Shin is collaborating with ENT specialists to outline indications and develop a pathway for patients with loss of smell and taste who may benefit from SGB. She currently evaluates patients who have had a confirmed COVID-19 diagnosis and have been diagnosed with COVID-related smell and taste disorder. She also encourages patients to see an ENT specialist first to make sure there isn’t an underlying issue.
“If you have a primary smell and taste disorder from trauma, sinusitis or other conditions, the nerve block may not change that,” says Dr. Shin.
In addition, contraindications for stellate ganglion block include glaucoma, coagulopathy, recent myocardial infarction, severe pulmonary disease, pre-existing counter lateral nerve palsy and cardiac conduction block. Potential risks of the procedure include bleeding and infection, as well as puncture of nearby structures, such as the trachea, esophagus, carotid artery and internal jugular.
“Overall, it’s a safe procedure, and we have found ways to improve the safety over the last several years, especially when it is image-guided, such as with ultrasound,” says Dr. Shin.
Advice for physicians
Dr. Shin suggests that physicians caring for patients with COVID-related olfactory disorder take the following steps:
Send patients to an ENT physician to confirm the diagnosis and rule out other conditions.
Consider olfactory training as the first-line therapy.
Refer the patient to a trained interventional pain management physician for an assessment for SGB.
“I am cautiously optimistic about this experimental treatment,” says Dr. Shin. “In the right person – someone who doesn’t have contraindications and the benefit outweighs the risk – the stellate ganglion block may be utilized for COVID-related smell and taste disorders.”

Revisión mecánica de la ambulancia
Llegar al lugar del servicio requerido con seguridad y rapidez depende, en parte, de tener el vehículo en óptimas condiciones de funcionamiento y de equipamiento. Es de vital importancia prestar mucha atención a nuestro vehículo y tenerlo siempre en muy buenas condiciones.
Estas indicaciones han sido elaboradas por la sección de Técnicos de SEMES

Agilizar el paso a los vehículos de emergencia podría aumentar un 40% la supervivencia en un accidente vial
Una ambulancia que llegue cuatro minutos antes podría aumentar un 40% las probabilidades de salvar la vida del accidentado. Pero si los vehículos se apartan sin orden al paso del vehículo de emergencias se ralentiza el traslado de los pacientes.
¿Sabe la población cómo actuar ante la presencia de un vehículo de emergencias? y ¿cómo hacer un “Corredor de Emergencias”?
