Unos investigadores han descubierto otro peligro para la salud asociado con vapear.
Inhalar los productos de vapeo podría dañar a una capa esencial de los pulmones, llamada surfactante. El surfactante está hecho de lípidos y proteínas, y posibilita que se respire con un esfuerzo mínimo al reducir la tensión superficial. Los investigadores afirman que la respiración requeriría má...
Researchers have uncovered another health hazard associated with vaping.
Inhaling vape products may damage a critical layer of the lungs called surfactant. Made of lipids and proteins, surfactant makes it possible to breathe with minimal effort by reducing surface tension. Researchers say breathing would require more effort and possibly mechanical help without this layer.
As three highly contagious respiratory viruses spread across the United States, straining hospitals and triggering drug shortages, health officials in some major cities and states are calling for a return to indoor masking.
Over the past few weeks, COVID-19, the flu and RSV have made millions of Americans ill, and indoor masking is seen as one way to slow the spread of the viruses.
Pediatricians' offices, children's hospitals, urgent care centers and emergency rooms across the United States are being overwhelmed by an early, heavy surge of respiratory syncytial virus (RSV) among infants and young children.
Reported cases of RSV started rising dramatically in September, and by mid-October were at their ...
People hospitalized for COVID-19 are not necessarily out of the woods once they're discharged: Many land in the hospital again in the months afterward, a large U.K. study finds.
The researchers found that in the 10 months after leaving the hospital, COVID-19 patients were more than twice as likely to be hospitalized or die, compared to the general population. And even compared with people...
Parent-collected nasal swab samples from kids could be as good at detecting respiratory infections such as COVID-19 as those taken by nurses, but that's not the case with saliva samples, British researchers say.
Respiratory infections such as colds and flu are among the most common illnesses in kids treated by primary care doctors. COVID-19 is also a respiratory infection.
The COVID-19 pandemic has offered some lessons on respiratory disease transmission, and now a new review suggests that hospitals could use those insights to create even smarter infection-control policies.
The review, published Nov. 9 in the Annals of Internal Medicine, suggests that some longstanding infection-control tactics at hospitals are "outdated."
Social distancing and mask mandates during the pandemic nearly eliminated cases of the flu and respiratory syncytial virus (RSV) among children, a new study finds.
"Numbers don't lie. Face masking, and proper hygiene and isolation, can be effective means to protect the vulnerable groups, such as the elderly and young children, during the respiratory virus season," said study author Dr. Os...
Surprisingly, patients who isolate before surgery to protect themselves from COVID-19 actually have a higher risk of lung complications after their operation than those who don't isolate, a new study reports.
The findings conflict with current guidelines that recommend isolation before surgery, researchers noted.
"Our evidence suggests that removing preoperative isolation strategies...
Breathing in air that has even low levels of pollution poses a threat to older adults' heart and lungs, a new study warns.
Researchers analyzed medical records of more than 63 million Medicare patients from 2000 to 2016. They found that long-term exposure to low levels of air pollution could increase the risk of pneumonia, heart attack, stroke and the irregular heart rhythm known as atria...
Old age and chronic health conditions aren't the only risk factors for serious COVID-19 infection. Researchers say people with high levels of the heavy metal cadmium may also have higher odds of severe disease during the pandemic.
Cadmium is found in cigarettes and in contaminated vegetables. Previous research has shown that long-term exposure to cadmium, even at low levels, may weak...
Getting vaccinated to protect against pneumonia and flu may offer an unexpected benefit -- a lower risk of Alzheimer's disease, new research suggests.
Two new studies being presented Monday at this summer's virtual Alzheimer's Association International Conference found a lower incidence of Alzheimer's in people who got flu and pneumonia vaccines. A third study underscored the importa...
Reports of serious, even deadly, vaping-linked lung injuries dominated the headlines late last year, then COVID-19 took over the news.
But those lung injuries haven't gone away, and signs of e-cigarette or vaping product use-associated lung injury (EVALI) can look a lot like a COVID-19 infection, federal and state health officials warn.
New research reveals that COVID-19 attacks the lungs in a far different manner from the flu.
Unlike most respiratory diseases, significant impacts on blood vessels were seen in the lungs of seven COVID-19 patients. The lung tissue of those patients was compared to lung tissue from seven people who died of pneumonia caused by the flu.
With a sudden need for more ventilators due to the coronavirus pandemic, researchers have been busy trying to come up with alternatives to a standard ventilator.
Engineers from Georgia Tech and Emory University in Atlanta think they may have developed such a device. They've created a simple, low-cost ventilator that builds on the widely used resuscitation bags found in ambulances and...
As COVID-19 pushes American hospitals to the breaking point, intensive care units are finding creative ways to deal with a looming shortage of lifesaving mechanical ventilators.
New York-Presbyterian Hospital last week began splitting single-use ventilators into machines that can serve two patients at a time. Now another New York-based hospital system, Northwell Health, has stepped up...
Fighting the flu can be an unpleasant experience -- but the misery may not stop there.
When you have the flu, your immune system is under attack, making complications common. Other infections can weasel their way into your body, according to Libby Richards, an associate professor at Purdue University's School of Nursing in West Lafayette, Ind.
Natural compounds added to marijuana-derived vaping liquid produce toxic chemicals in the vapor that users inhale, a new lab study reports.
The compounds, known as terpenes, are added into pure THC distillations to dilute the product and provide the vapor with aroma and taste, said senior researcher Robert Strongin, a professor of organic chemistry at Portland State University in Ore...
Seasonal flu and other respiratory infections may be especially dangerous for kidney failure patients, researchers say.
A new study found that influenza-like illnesses likely contribute to more than 1,000 deaths among kidney failure patients in the United States each year. These illnesses include potentially serious respiratory tract infections caused by flu and other viruses.
It's not too late to get your flu shot, which can protect you in ways that may surprise you.
The flu vaccine can be a lifesaver for people with heart disease, according to infectious disease specialist Dr. Michael Chang, assistant professor of pediatrics at University of Texas Health Science Center at Houston.
"Previous studies have shown influenza vaccination could reduce d...
