THURSDAY, March 4, 2021 (HealthDay News) -- 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 he...
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...
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.
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...
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...
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.
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.
Older adults exposed to air pollution might have a heightened risk of abnormal "plaque" accumulation in the brain, a new study suggests.
Plaques refer to clumps of protein called beta-amyloid that build up in the brains of people with Alzheimer's disease. In the new study, researchers found that among older adults with memory and thinking problems, those exposed to higher levels of air po...
The spice that adds punch to your favorite Kung Pao chicken, Tex-Mex chili or Indian curry may also help save your life.
Preliminary research shows that eating chili pepper may reduce your risk of death from heart disease, cancer and other causes, building on past studies that have found chili pepper to have health benefits.
"I think a lot of people are going to find this informatio...
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 ...
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.
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...
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...
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.
If you can't sleep well at night, the problem may be rooted in hardened arteries, a new study suggests.
"We've discovered that fragmented sleep is associated with a unique pathway -- chronic circulating inflammation throughout the bloodstream -- which, in turn, is linked to higher amounts of plaques in coronary arteries," said researcher Matthew Walker. He's a professor of psychology...
Reports of children suffering from a serious coronavirus-linked inflammatory condition have scared parents everywhere, but new research suggests that treatment with COVID-19 antibodies might help in the worst cases.
The inflammatory condition, now known as Multi-System Inflammatory Syndrome in Children (MIS-C), mimics some of the symptoms seen in toxic shock syndrome and a serious hea...
A new study offers reassurance that many surgery patients can safely be freed from one discomfort of recovery -- wearing compression stockings to prevent blood clots.
The garments, which help keep blood from pooling in the lower legs, have long been used post-surgery. One reason has been to thwart blood clots, which can form in the leg veins when a patient is laid up in recovery.
As New York City officials grapple with the sudden appearance of a rare inflammatory condition in children exposed to COVID-19, a new Italian report describes similar cases that have cropped up in that country.
The researchers say their findings provide "the first clear evidence" of a link between the new coronavirus and this inflammatory condition.
There's been much speculation about whether vitamin D might prevent or help survival with COVID-19, and two new studies appear to underscore the link.
In the first study -- published in the journal Aging Clinical and Experimental Research -- British researchers found that COVID-19 infections and deaths were higher in countries where people had low vitamin D levels, such as Ita...
Amid recent warnings about a possible link between COVID-19 in children and an inflammatory condition called Kawasaki disease that can harm the heart and other organs, heart experts stress that such cases seem to be rare.
Most kids with COVID-19 have mild symptoms or none at all, but a small number have developed Kawasaki disease, often requiring hospitalization and occasionally, inte...
The severity of COVID-19 illness may be influenced by what researchers call "cytokine storms."
In a new study, investigators assessed 522 COVID-19 patients, aged 5 days to 97 years, who were admitted to two hospitals in Wuhan, China, in December and January. The study also included a "control group" of 40 healthy people.
Compared to the control group, 76% of COVID-19 pat...
Children don't typically fall seriously ill from the new coronavirus, but doctors are raising the alarm that some kids with COVID-19 infections in Europe have developed Kawasaki disease, a condition that can trigger serious heart problems.
Children in the United States aren't immune to this complication, experts say.
Dr. Michael Portman is director of the Kawasaki Disease P...
As researchers hunt for ways to treat severe COVID-19 infections, a new trial will ask whether an old arthritis drug can prevent serious complications in the first place.
The medication, called colchicine, is an oral anti-inflammatory that has long been prescribed for gout, a form of arthritis. Its history goes back thousands of years, and the drug was first sourced from the autumn cr...
It's clear that age and chronic disease make bouts of the pandemic coronavirus more severe -- and even deadly -- but obesity might also put even younger people at higher risk, a pair of new studies suggest.
The researchers suspect that inflammation throughout the body linked to obesity could be a powerful factor in the severity of COVID-19, the disease caused by the coronavirus.
People taking steroids to treat chronic inflammatory diseases are at high risk for developing high blood pressure, British investigators report.
Inflammatory bowel disease and rheumatoid arthritis are often treated with steroids for an extended period, at high doses, and as many as a third of patients in the study became hypertensive, the scientists said.
