Because they can cause death within minutes if no one performs CPR or uses a defibrillator to return the heart to a normal rhythm. Researchers examined cardiac arrests in 14 counties affected by wildfires in California between 2015 and 2017. Exposure to smoke density was rated as light, medium, or heavy based on National Oceanic and Atmospheric Association mapping data. The researchers compared smoke exposure on the day of the fire with exposure on the same day of the week in the previous 3 weeks. They also compared exposure 1, 2, and 3 days before the fire with exposure on corresponding days in the 3 weeks before the cardiac arrest. The analysis found that the risk of out-of-hospital cardiac arrest increased on days classified as high smoke density and for several days afterwards, with the highest risk (70% higher than on smoke-free days) on the second day after from smoke exposure; increased in both men and women and in people aged 35 years or older exposed to heavy smoke; and increased in lower socioeconomic communities (20% or more people living below the poverty line) with both medium and heavy smoke exposure.
"Smoke particles that are inhaled can penetrate deep into the lungs, and very small particles can cross into the bloodstream. These particles can create an inflammatory reaction in the lungs and throughout the body. The body's defense system can react to activate the fight or flight system, increasing heart rate, narrowing blood vessels and increasing blood pressure. These changes can lead to alterations in the normal rhythm of the heart, blockages in blood vessels and other effects that create conditions that could lead to cardiac arrest," explain the authors of the research. To reduce exposure to wildfire smoke, researchers Oman WhatsApp Number advise people to stay indoors with doors and windows closed, use high-efficiency air filters in air conditioning systems, avoid exertion, and Consider seeking shelter elsewhere if the house does not have air conditioning and it is too hot to stay indoors.An Ebola vaccine could combat all four virus species, according to first studies by Agencies April 18, 2020 08:42 Scientists at Cincinnati Children's Hospital Medical Center in the United States have reported the development of a potential universal Ebola vaccine that, according to preclinical testing, could neutralize all four species of these deadly viruses that infect people in recent outbreaks. , mainly in Africa.
Although they are still in early preclinical testing, the researchers say their data indicates that the potential vaccine has the potential to provide comprehensive protection against Ebola. It could also broaden and extend the durability of the protective immunity induced by current live vaccines that are already being tested in clinical trials against individual species of the virus, explains Karnail Singh, lead author of the work, which has been published in the journal 'Journal'. of Virology'. "This could be a significant advance in the global effort to prevent or manage Ebola outbreaks, especially if this vaccine used alone or in combination with another Ebola vaccine results in durable, long-term protective immunity against different Ebola viruses." insists Singh. While live vector vaccines are producing encouraging results in clinical trials, until this new research, none of the new vaccines being developed have been shown to induce immune responses that cross-react against the multiple species of the virus that cause the fatal disease in humans.
