What to Know About Pulse Oximeters

If you use an oxygen concentrator and a pulse oximeter at home, proper use is crucial, the U.S. Food and Drug Administration says.

Conditions such as asthma, lung cancer, chronic obstructive pulmonary disease, the flu and COVID-19 can all cause oxygen levels in the body to drop. When levels are too low, oxygen therapy may be required to boost them.

One way to get extra oxygen ...

Your Blood Type May Predict Your Risk For Severe COVID-19

There's more evidence that blood type may affect a person's risk for COVID-19 and severe illness from the disease.

The findings are reported in a pair of studies published Oct. 14 in the journal Blood Advances.

In one, researchers compared more than 473,000 people in Denmark with COVID-19 to more than 2.2 million people in the general population.

COVID-19 ICU Patients Have High Risk of Clots, Research Shows

Hospitalized COVID-19 patients face an increased risk of developing dangerous blood clots, a new review indicates.

The odds of a clot are highest for the most critically ill patients. Analysis of 66 studies found that 23% of COVID-19 patients in an intensive care unit (ICU) developed a blood clot in the leg, known as a deep vein thrombosis (DVT).

Overall prevalence of ...

COVID-19 Antibodies Decline Quickly in Donated Plasma: Study

Antibodies against COVID-19 in people who've recovered from the disease begin to vanish about three months after they develop symptoms, researchers say.

This suggests that sooner is better for recovered COVID-19 patients to donate antibody-containing blood plasma for convalescent plasma treatment, according to the authors of a small study published Oct. 1 in the journal Blood.<...

Blood Test Could Spot Those at Highest Risk for Severe COVID-19

If you're unfortunate enough to be admitted to the hospital with COVID-19, a common blood marker may predict how severe your illness might become, new research shows.

The blood marker is called "red cell distribution width" (RDW) -- basically, the greater the variance in the size of red blood cells, the poorer a patient's prognosis, the study authors explained.

A COVID-19 pa...

Small Study Supports Donor Plasma Therapy for Severe COVID-19

Using the donated blood plasma of COVID-19 survivors to treat patients in the throes of severe coronavirus illness has met with some controversy. But a small new study suggests it could have real merit.

Early Trial Offers New Hope for People With Hemophilia

Researchers may have found a way for people with severe hemophilia to take their standard treatment less often, if the results of an early trial pan out.

In what experts called a feat of bioengineering, scientists were able to create a "fusion protein" that may extend the interval between treatments for hemophilia -- from about every couple of days to once a week.

The early ...

Rare 'Brain Vein' Strokes Are on the Rise

Most strokes strike when an artery in the brain suddenly becomes blocked, but new research shows a rarer cause of strokes is becoming more common.

It's called cerebral venous thrombosis (CVT), and it happens when a vein in the brain is clogged. While CVT is estimated to cause less than 1% of all strokes, scientists discovered it is now more prevalent and affecting a different demo...

Transfusions of COVID Survivor Blood a Safe Treatment for Patients

Blood plasma transfusions from people who have developed antibodies to the new coronavirus appear to be safe for many COVID-19 patients, a large study suggests.

The experimental treatment -- called convalescent plasma therapy -- is popular because no drug has been approved specifically to treat coronavirus infection.

A week after 20,000 COVID-19 patients deemed at risk for ...

Researchers Latch Onto the Leech's Genome

A mainstay of 18th-century medicine -- the lowly leech -- has made something of a comeback in the 21st century. That's largely due to powerful blood thinners the parasitic worm secretes naturally.

Now, genetic research could give a major boost to the medical use of leeches, scientists say.

An international team sequenced the genome of a European leech called Hirudo medici...
