Aunque los vapeadores se habían presentado como una alternativa saludable al tabaco, se han descubierto en ellos  efectos negativos para la salud debido a un conjunto de sustancias que pueden llegar a ser potencialmente mortales.
El graduado en Ciencias ambientales de la Universidad Miguel Hernández (UMH) de Elche, Daniel Muñoz Ortiz, ha centrado su trabajo de Fin de Grado en estudiar la peligrosidad de las sustancias químicas contenidas en los aerosoles que se generan durante el consumo de cigarrillos electrónicos.
Del total de 127 compuestos encontrados, varios son venenosos , provocan cáncer, alteraciones genéticas o problemas de reproducción.
En 2019 se alertó sobre los primeros casos de Lesión Pulmonar Asociada al Cigarrillo Electrónico.
De todas estas investigaciones se ha concluido que no existe una dosis umbral que podamos considerar segura. Es decir, tanto los usuarios vapeadores como quien está a su alrededor corren el riesgo de sufrir las consecuencias.

This summer at `La Paz´ hospital, in Madrid, Emma, a 13 month old baby who suffered from intestinal failure, has received the word’s first transplant of a donated intestine in asystole (the donation of organs and tissues that come from a person who is diagnosed dead after confirmation of the irreversible cessation of cardiorespiratory functions). This technique makes possible the use of solid organs that would otherwise be lost. This surgery has been done by the doctor Francisco Hernández Oliveros, who is from Granada.

Somes home remedies are:
- Vitamin C and echinacea infusions shorten illness by a day.
- Zinc supplements, but can have side effects.
- Ginger or turmeric, but it is not known how much should be added to the food for it to work.
- Stay hydrated with water, herbal teas, orange juice, hot broth, lemon juice with honey... But they should never be cold. This reduces discomfort.
- For a sore throat, sucking on hard candy is very helpful.
- If you can't breathe properly, it helps to breathe out with eucalyptus leaves, or inhale saline or salt water through the nose.
- And for pain, anti-inflammatory drugs are best.
But the most important thing is to always stay well hydrated and rest.

Turning down the volume isn't just something annoying parents are asking for: A new study shows it could protect more than 1 billion people at risk of hearing loss.

When it comes to phones, music, movies and shows, it's common for teens and young adults to listen too loudly and for too long, according to the study published Tuesday in the academic journal BMJ Global Health.

"We estimate that between 670 and 1.35 billion people aged 12 to 34 worldwide have unsafe hearing practices" and are therefore at risk of hearing loss, the study's lead author, Lauren Dillard, said by email. Dillard is a consultant to the World Health Organization and a postdoctoral fellow at the Medical University of South Carolina.

Exposure to sound at too loud a volume can fatigue sensory cells and ear structures, Dillard explains. If this goes on too long, they can be permanently damaged, leading to hearing loss, tinnitus, or both.

"Music is a gift to be enjoyed for a lifetime," said Swanepoel, who is also editor-in-chief of the International Journal of Audiology. "The message is that you have to enjoy the music, but safely."

The flu is a constant threat that causes more than half a million deaths each year in the world.

Some years ago a lot of scientist shearched for a universal vaccine against it.

But a study that was published on Thursday the 24th in ‘Science' make us closer to this objective. According to the information that they gave, some American scientist have discovered a universal vaccine against the flu, that for the moment acts correctly in animals models.

The development of this test was carried out  by ARN messenger technology, it's a type of technology based on the ARN vaccines (a process that causes an immune response that protects from the infection).

That approach, made possible for the Institute for Immunology from University of Pennsylvania create a vaccine with 20 antigens belonging to all the subtypes of the  virus A and B of the flu.

The pharmaceutical company Eisai announced that their drug, Lecanemab, has shown small but clear benefits for people with early Alzheimer’s in a rigorous, well-conducted phase 3 trial.

It works by removing a protein called amyloid from the brain, but it’s the first drug that’s been shown to slow down patients’ decline in memory and thinking, and improve day-to-day activities. And although the effects are modest, with the potential for some significant side effects, this nonetheless marks a turning point – the arrival of a treatment that is proven to slow the course of Alzheimer’s disease.

It is, truly, a historic moment for dementia research and perhaps proof that scientific research on dementia and the diseases that cause it will lead to effective treatments.

As UK experts remarked to the media, while this is the “end of the beginning” of the search for effective treatments, there are many obstacles ahead that need to be cleared before the drug can be made available to people.]]> 2022-12-04 18:33:50 UTC https://padlet.com/maadarvebilogia/x1mhw8p2kr67xtvy/wish/2408186208
