“Roughly two and a half years into the pandemic, White House officials and health experts have reached a pivotal conclusion about Covid-19 vaccines: The current approach of offering booster shots every few months isn’t sustainable.
Though most vaccines take years to develop, the Covid shots now in use were created in record time—in a matter of months. For health authorities and a public desperate for tools to deal with the pandemic, their speedy arrival provided a huge lift, preventing hospitalizations and deaths while helping people to escape lockdowns and return to work, school and many other aspects of pre-Covid life.”
Duke’s Telestroke Network gives patients and doctors at five NC and VA hospitals access to Duke stroke specialists 24/7. Now, patients at these hospitals get the immediate care they need.
The mantra of The Johns Hopkins Hospital’s Comprehensive Stroke Center is “time is brain.” Innovations and teamwork help ensure that this mantra applies to all stages of stroke recovery. Take a peek into the multifaceted treatment strategies offered by the center’s team of experts.
These include stroke risk screenings, hyperacute emergency treatments, innovative hospital care such as digital therapeutics, early rehabilitation, programs to ensure smooth transitions to home, and cutting-edge clinical research. The Stroke Center team is on a mission to improve the life of every patient who has had a stroke. #Stroke #JohnsHopkins
In a nonrandomized controlled intervention study published in JAMA, researchers in Germany assessed whether deployment of a flying interventional team, consisting of a neurointerventional radiologist and an angiography assistant, was associated with a shorter time to endovascular thrombectomy for patients in rural or intermediate population areas in Southeast Bavaria.

Stroke prevention by a healthy lifestyle, including a good diet, regular exercise, and sleep is of course preferable to treatment.
However, stroke still claims more than 100,000 lives per year in the United States, and is a major factor in disability.
Recognition of a stroke is the first crucial step, and has been discussed in DWWR previously; FAST is the Menmonic and guiding principle. Ask the patient to smile, and it may be assymmetric, with one side drooping. Ask the patient to raise both arms, and one may drift down. Ask the patient to repeat a simple sentence, and he may be unable to do so. And above all be speedy, since time is of the essence, and treatment must take place within a very few hours.
Modern medical centers in large cities frequently have a team dedicated to treating stroke. The patient goes for a CT or MRI while the Catheter team assembles. An intravenous clot dissolver, tPA, is often used, or possibly a catheter is inserted into an artery and guided to the proper location. Sometimes the clot is mechanically removed as in the accompanying video.
The helicopter stroke response team featured in the posting is one aspect of the speed that is so essential; any delay will result in death, sometimes permanently, of brain cells.
Acute Heart attack treatment is basically similar to stroke, and was the pioneering venture into the interventional radiology described above. Also, the heart may be the source of the clots that lodge in the brain, especially from atrial fibrillation.
Please enjoy the following video which shows how mechanical clot removal is achieved.
AI can pick up on subtle clues from a person’s physiological state such as their heart rate, the time differences between each heartbeat or the electrical signals their heart produces in order to identify irregularities that point to medical conditions.
“Being able to detect atrial fibrillation just by wearing a wristwatch all the time, that kind of relatively simple technology could actually have a massive impact,” explained consultant cardiologist Tim Fairbairn, cardiovascular imaging lead at Liverpool Heart and Chest Hospital in the UK.
AI has the power to transform health care. From more efficient diagnoses to safer treatments, it could remedy some of the ills suffered by patients. Film supported by @Maersk

New high-tech Covid-19 tests promise better and earlier detection of the virus—similar to a PCR test. WSJ’s Joanna Stern (and her mannequin clone) tried out the Detect Covid-19 Test and Cue Health Monitoring System to see how they compare with rapid antigen tests. Photo illustration: Ryan Trefes/ WSJ
