Here are the top medical news for the day:
Transition to newer clot-busting drug improves patient outcomes and lowers treatment cost
A newer-generation clot-busting drug called Tenecteplase outperforms the traditional treatment for ischemic strokes in several key areas, including better health outcomes and lower costs, according to a new study published today in the American Stroke Association's journal Stroke.
Nearly 800,000 people in the United States have a stroke every year. The vast majority of those strokes (about 87%) are ischemic, meaning they occur when a vessel supplying blood to the brain is obstructed by a blood clot. This can result in a corresponding loss of neurologic function.

Gut bacteria and metabolites strongly linked
There are strong links between bacteria living in the gut and the levels of small molecules in the blood known as metabolites. Such is the finding of a new study led by researchers from Uppsala University and Lund University, which is now published in the journal Nature Communications.
A team of scientists coordinated by Uppsala University and Lund University has found strong links between certain bacteria living in the gut and small molecules found in the blood. The study is based on analyses of both fecal and blood samples from 8,583 participants in the Swedish Cardio Pulmonary bioImage Study (SCAPIS).

Acquired immunity against random food allergens may offer immunity against COVID-19 to few
A recent study in open-access journal Frontiers in Immunology finds that common foods, vaccines, bacteria and viruses may all prime our immune system to attack SARS-CoV-2, the virus that causes Covid-19. These agents all contain proteins that are similar to those found in SARS-CoV-2.
Proteins present in bacteria, human cells, vaccines, and even foods may all share similarities with those in SARS-CoV-2. The researchers behind this latest study hypothesized that similarities between SARS-CoV-2 and other common proteins may affect our susceptibility to the virus.
