An experimental injectable drug appears more versatile than existing medications in treating people with different forms of severe, hard-to-control asthma, clinical trial results show.

There are many different types of asthma brought on by many different triggers, and a number of monoclonal antibody medications -- called "biologics" -- have been crafted to target distinct asthma triggers....

Heart complications are rare among college athletes who have had COVID-19, according to a small study.

"Our findings may offer reassurance to high school athletes, coaches and parents where resources for testing can be limited," said senior author Dr. Ranjit Philip, assistant professor in pediatric cardiology at the University of Tennessee Health Science Center, in Memphis.

For the ...

While COVID-19 research efforts must now shift toward the development of a pill that can prevent serious illness in the recently infected, experts say.

"We need a pill that can keep people out of the hospital, and the time to develop that is right now," Dr. Rajesh Gandhi said during a Thursday media briefing by the Infectious Diseases Society of America. He is director of HIV Clinical Ser...

In rare cases, people hospitalized for COVID-19 can develop heart failure, even if their hearts were previously healthy, new research shows.

The researchers found that of over 6,400 COVID-19 patients at their hospital, 0.6% newly developed heart failure. That included eight patients -- mostly relatively young men -- with no history of heart disease or risk factors for it.

Heart fail...

As if the headaches and stuffy nose aren't bad enough, chronic sinus trouble often leaves patients foggy-headed and depressed. Now, new research suggests one possible reason why: Sinusitis may trigger changes in brain activity.

"Chronic sinusitis is incredibly common," said study lead author Dr. Aria Jafari. Upwards of 11% of all Americans are affected, added Jafari, an assistant profess...

People who eat plenty of vegetables, fish and fiber may have more inflammation-fighting bacteria in their guts, but fast-food lovers may be feeding inflammatory microbes.

That's the conclusion of a new study that looked at people's diet habits and the makeup of their gut "microbiome."

The term refers to the vast collection of bacteria and other microbes that naturally dwell in the g...

Dermatologists liken skin to a window that can reveal what is going on inside the body, and a rash that sometimes follows a COVID-19 vaccine is one example.

When you get the shot, your immune system activates, preparing to recognize and fight off the virus in the future. This response and the inflammation that goes with it can occasionally result in a rash. But experts say as long as it h...

In very rare cases, children infected with the new coronavirus can develop a severe illness known as multisystem inflammatory syndrome (MIS-C). Now, research finds that these young patients often develop neurologic symptoms along with the respiratory issues they might face.

These neurologic symptoms were present in half of children who were hospitalized with MIS-C, U.K. researchers say.

Don't forget to floss: New research adds to evidence linking gum disease with Alzheimer's disease.

The mouth is home to both harmful bacteria that promote inflammation and healthy, protective bacteria, the study authors explained.

In the new study, the researchers found that people who have more harmful than healthy gum bacteria were more likely to also have a protein marker for Al...

Once you've landed that coveted coronavirus vaccine appointment, you'll likely have to fill out a form on your medical history and whether you're allergic to any of the vaccine's ingredients. But there could be another question waiting for you: Have you ever had dermal filler injections?

That's because -- in rare cases -- people who've had the face-plumping injections can develop a mild, ...

In a discovery that shows carpal tunnel syndrome doesn't strike just office workers, researchers report that people who work in construction or manufacturing have a higher risk of carpal tunnel syndrome than those with desk jobs.

Why the higher rates of injury among manual laborers? Investigators found such work requires lifting, gripping and forceful wrist motion, all of which are associ...

In January, the coronavirus swept through Brian and Maria Padla's family of seven in Philadelphia, starting with their oldest daughter, 16, and then infecting Brian, Maria, and their four younger children.

The virus seemingly came and went without much fanfare for the family. During their two-week-long quarantine, the kids spent a day or two with runny noses and low-grade fevers. Brian an...

When people die some cells in their brains go on for hours, even getting more active and growing to gargantuan proportions, new research shows.

Awareness of this activity, spurred on by "zombie genes," could affect research into diseases that affect the brain.

For the study, researchers analyzed gene expression using fresh brain tissue collected during routine surgery and found that...

Yet another organ seems to be affected by a bout of COVID-19: the thyroid.

Italian researchers have examined the thyroids of dozens of patients who've recovered from moderate-to-severe cases of COVID-19. The study found evidence that SARS-CoV-2 infection may trigger an inflammation of the gland in some patients.

Whether that inflammation can cause long-term dysfunction is still unc...

For many, it's like emerging suddenly from a long, dark tunnel.

Some people who've been laid low for months by so-called "long haul" symptoms after a coronavirus infection say that within days of getting their COVID-19 vaccine, those symptoms nearly disappeared.

Speaking with The New York Times, Bridget Hayward, a 51-year-old operating room nurse in Alexandria, Va....

A new tissue infection has been identified in Crohn's disease patients, and researchers say their finding could ultimately lead to better treatment of the common inflammatory bowel disease.

Areas of unhealed wounds in the intestines of Crohn's patients have elevated levels of a type of yeast widely found in cheese and processed meat, the new study found.

The researchers discovered t...

Like many people this past year, teenager Tyona Montgomery began experiencing a sore throat and a loss of sense of smell and taste in November that suggested she might have COVID-19.

A positive test confirmed it, but she quickly felt better.

Then, just two weeks later, new symptoms surged. She was disoriented, with a headache that was so bad she called an Uber to take her to a hospi...

Two new studies suggest that the jury is still out on whether the arthritis drug tocilizumab helps those with severe COVID-19.

Both reports were published recently in the New England Journal of Medicine. The first, from scientists at the University of California, San Diego, found tocilizumab didn't improve outcomes or reduce the risk of death in patients with severe COVID-19 pneu...

One side effect of COVID-19 vaccination is creating undue fear among women, causing them to worry that they might have breast cancer.

Both the Pfizer and Moderna vaccines can cause lymph nodes to swell, particularly those in the armpit on the side where the shot was received, experts say.

Some women are feeling these armpit lymph nodes and mistaking them for breast lumps, according ...

Certain genetic factors in people with Down syndrome may increase their COVID-19 risks.

Previous studies have found that people with Down syndrome are 10 times more likely to die from COVID-19, and experts have said they should be among those given priority for vaccination.

In this new study, Spanish researchers examined genetic differences in people with Down syndrome that might af...

Keep flossing: A new study finds that gum disease may raise the chances of hospitalization or death if COVID-19 strikes.

The reason? Gum disease can be a sign of inflammation throughout the body.

"It is well-established that systemic inflammation is not only linked with periodontal disease, but to several other respiratory diseases as well," explained Dr. James Wilson, president of...

Full doses of blood thinners can benefit patients hospitalized with COVID-19, but the severity of their illness matters, researchers say.

The new global analysis found that hospitalized patients with moderate COVID-19 may benefit from the drugs' clot-preventing powers, but patients with illness so severe it requires admission to an intensive care unit may not.

"SARS-CoV-2 infectio...

Here's one reason why past or current smoking may handicap you if you are battling breast cancer: New research suggests that nicotine promotes the spread of the disease to your lungs.

Smoking is known to increase the risk that breast cancer will spread, which lowers the survival rate by one-third at diagnosis. But the role of nicotine in the spread of breast cancer to the lungs has been l...

The arthritis drug tocilizumab doesn't help hospital patients with severe COVID-19, according to a new study that contradicts earlier research suggesting that it might aid recovery.

In fact, patients receiving tocilizumab had a higher risk of death, so the trial was halted early.

Tocilizumab blocks a part of the immune system (interleukin 6) that can become overactive in some COVID...

New research offers a novel explanation for the long-term brain problems many COVID-19 patients experience.

Many coronavirus patients report headaches and "brain fog" for weeks or months after they recover from respiratory symptoms. It's been believed that these lingering neurological issues are the result of nerve cell damage, but the new study suggests that the virus may instead be stri...

Stem cells derived from a baby's umbilical cord can help save the lives of the sickest COVID-19 patients, results from a small new clinical trial suggest.

Severely ill COVID patients who received two intravenous doses of stem cells three days apart were much more likely to survive and recover quickly, researchers found.

"The results are quite spectacular," said senior researcher Dr....

Teenagers who use e-cigarettes may be at increased risk of "mental fog," a new study suggests.

The study, of thousands of U.S. teens, found that those who vaped were three times more likely than their peers to report problems with concentration, memory and decision-making.

The findings mirror those of a recent study of adults by the same research team: Men and women who used e-...

Blood vessel damage and inflammation in the brains of deceased COVID-19 patients suggest the damage is not caused by the virus, but the body's immune response to it.

Researchers from the U.S. National Institutes of Health (NIH) consistently found signs of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after getting COVID-19.

...

Respiratory problems and other factors -- not inflammation -- may explain why obese people are more likely to have severe COVID-19 and die from it, according to a new study.

Other studies have shown that overweight and obese COVID-19 patients are more likely to be admitted to intensive care, to require mechanical ventilation, and to die. Population-level studies also indicate that countri...

Compounds in meat may trigger wheezing in some children that can potentially lead to asthma or other respiratory conditions, a new study suggests.

These compounds, called advanced glycation end products (AGEs), are released as meat is cooked at high temperatures while grilling, frying or roasting. AGEs attach themselves to cells in the lungs, causing inflammation and an immune system resp...

While loss of smell is a symptom of COVID-19, don't panic -- there are a variety of other possible causes, one expert says.

"It can be due to nasal or sinus inflammation, or other viral infections distinct from COVID-19," explained Dr. Bobby Tajudeen, director of rhinology, sinus surgery and skull base surgery at Rush University Medical Center in Chicago.

"And it can even occur as a...

Rheumatoid arthritis patients who are in remission have significantly higher body temperatures than people without the joint disease, new research shows.

The study included 32 rheumatoid arthritis patients who were in remission and a healthy "control" group of 51 people without rheumatoid arthritis, who all had thermal scans of different areas of their feet.

"These tests demonstrate...

A stronger immune system and healthier blood vessels are among reasons kids are less likely than adults to have severe COVID-19, according to experts who reviewed research from around the world.

"Most children with COVID-19 have no or only mild symptoms, most commonly fever, cough, sore throat and changes in sense of smell or taste. Even children with the usual risk factors for severe inf...

Older adults exposed to air pollution might have a heightened risk of abnormal "plaque" accumulation in the brain, a new study suggests.

When the new coronavirus pandemic first began, respiratory distress immediately became the hallmark of severe COVID-19 illness. News reports focused on the inability to breathe, low oxygen saturation levels and the alarming need for ventilators.

But six months later, experts are becoming increasingly concerned about a very different COVID-19 phenomenon, one that spares the lungs only ...

The so-called love hormone, oxytocin, may be worth investigating as a treatment for COVID-19, a new study suggests.

One of the most serious complications of infection with the new coronavirus is a "cytokine storm," in which the body attacks its own tissues.

There are currently no U.S. Food and Drug Administration-approved treatments for COVID-19, which means that "repurposin...

The human body apparently disagrees with Mother Nature on how many seasons there are.

Instead of four seasons, human biology appears to have two, according to a team of Stanford University researchers.

"We're taught that the four seasons -- winter, spring, summer and fall -- are broken into roughly equal parts throughout the year, and I thought, 'Well, who says?' " said Mich...

People suffering from a psychiatric disorder could be more than twice as likely to die if they become infected with COVID-19, a new study suggests.

Folks diagnosed with any type of psychiatric problem -- anxiety or depression, dementia, psychosis -- were up to 2.3 times more likely to die in the hospital from COVID-19, researchers found.

"Those who had COVID who had a prior ...

Childhood risk for developing the allergic/autoimmune disorder known as celiac disease might be eliminated if infants were exposed to gluten as early as 4 months of age, new British research suggests.

The observation is based on work with 1,300 infants. Half were exposed to solid foods -- including wheat protein -- at an age that conflicts with current breastfeeding guidelines. Among...

Biologic therapy for the skin condition psoriasis may reduce patients' risk of heart disease, new research suggests.

Chronic inflammation in people with psoriasis is associated with the development of plaque in heart arteries, which increases the risk of coronary artery disease. In biologic therapy, patients receive protein-based infusions to reduce inflammation.

"This is th...

A simple blood test may predict which COVID-19 patients are likely to get worse and die, a new study suggests.

"When we first started treating COVID-19 patients, we watched them get better or get worse, but we didn't know why," said researcher Dr. Juan Reyes. He's an assistant professor of medicine at the George Washington School of Medicine and Health Sciences, in Washington, D.C.

There are currently no medications that can slow down the common form of arthritis that strikes aging knees and hips. But a new study suggests a powerful, and expensive, anti-inflammatory drug could potentially do just that.

The drug, called canakinumab (Ilaris), is used for certain rare rheumatic conditions marked by widespread inflammation. They include juvenile idiopathic arthritis...

The steroid medication dexamethasone has been proven to help people severely ill with COVID-19. Now a new study hints that other drugs in the same class may also work -- in the right patients.

The findings are from a review of one hospital's experience, not a clinical trial. So researchers said the results should be interpreted with some caution.

But the study suggests that ...

Bats have been blamed as a possible source of the new coronavirus pandemic ravaging the globe. But they might also point to possible ways out of it.

An infusion of cells that dampen the body's immune response might help people with severe cases of the new coronavirus recover more quickly, a new report suggests.

Two patients so sick with COVID-19 that they'd been put on a ventilator improved quickly when given an infusion of regulatory T-cells, which are cells that check the immune system and prevent it from overreacting to an infe...

Early and intensive treatment with methotrexate and prednisone can ease fatigue in people with rheumatoid arthritis (RA), according to a new study.

RA causes chronically inflamed joints and that inflammation can lead to severe fatigue that isn't relieved by resting, according to the European League Against Rheumatism (EULAR).

"In addition to pain, profound fatigue reduces th...

Kids as young as age 8 can show signs of being at increased risk for diabetes in adulthood, a British study finds.

Researchers analyzed blood samples collected from more than 4,000 participants at ages 8, 16, 18 and 25, looking for patterns specific to early stages of type 2 diabetes development.

"We knew that diabetes doesn't develop overnight. What we didn't know is how e...

There's new evidence that a 2,000-year-old medicine might offer hope against a modern scourge: COVID-19.

The medication, called colchicine, is an anti-inflammatory taken as a pill. It's long been prescribed for gout, a form of arthritis, and its history goes back centuries. The drug was first sourced from the autumn crocus flower.

Doctors also sometimes use colchicine to tre...

Could a cancer drug spare hospital patients from the ravages of severe COVID-19?
