Non invasive cardiac output monitoring
Conventionally, measurement of cardiac output was done invasively. Initially with dye dilution techniques and later by thermodilution techniques. Both needed pulmonary artery catheterization, which in turn was likely to cause morbidity if used for continuous monitoring. Almost all non-invasive cardiac imaging modalities like echocardiography, computed tomography, magnetic resonance imaging and nuclear imaging can measure cardiac output. But these are not suitable for bedside monitoring, though echocardiography may be used for intermittent bedside assessment.
Assessment of cardiac output though desirable, was most often ti...

COVID-19 vaccines for children and teens: What we do — and don’t — know
Vaccines have been heralded as a key measure to slow the COVID-19 pandemic and one day bring it to an end. Every day, millions of American adults are receiving one of the authorized vaccines proven highly effective at preventing severe illness that might otherwise lead to hospitalizations and deaths. In the US, most people over 65 have now been fully vaccinated, protecting the most vulnerable in our population.
As an infectious disease specialist, my responses to the questions below are based on what we know so far about infection and vaccines in children and teens. We’ll need to continue filling in gaps as research is d...

Wireless Sensor Measures Deep Tissue Oxygen Levels
Researchers at the University of California, Berkeley have developed an ultrasound-powered implantable sensor that can measure oxygen levels in tissues deep within the body and transmit these data to an external device. The technology could be useful in monitoring transplant viability or oxygen exposure in preterm infants. It also has potential to be adapted to measure other biochemical markers, such as carbon dioxide concentrations or pH levels.
Oxygen is crucial for living tissues, and poor oxygenation leads to cell death. This process forms the basis for various pathological phenomena, but clinicians can struggle to ...

Basic echocardiographic views
Echocardiography is now not restricted to the echocardiographic laboratory. It is used in the emergency department, at bedside, in the intensive care unit as well as in the operating room. Hence a basic knowledge is needed for all physicians and paramedics. Transthoracic echocardiography is often done from four echo windows. Echo windows are regions on the chest which permit imaging of the heart with least covering by the lungs.
Echocardiographic windows
The four common locations at which the echocardiographic transducer is placed for imaging are the parasternal, apical, subcostal, and suprasternal. Parasternal views are...

Correlative Adventures with COVID
By ANISH KOKA
“The patient in room 1 should be a quick one, its an addon, they just need a prescription for ivermectin”
I’m a bit puzzled by this sentence from my assistant doing his best to help me through a very busy day in the clinic that I’m already behind in. I walk into the room, a script pad stuffed into my hand as I enter the room, to meet a very nice couple. The wife sits patiently with hands crossed on the exam table.
“So, you’re here for Ivermectin?”, I ask.
Why yes, a trip to Texas is planned.. COVID is in the air, the internet, and some important people who have ‘inside ...

The Candy in My Pocket with John Robert Wiltgen
I had a chance to catch up with John Robert Wiltgen, the fascinating international award-winning JRW Design founder. I’m enjoying his recent blog posts and stories and want to spread the word in case you might enjoy them too.
John was diagnosed with diabetes at 8 years old. He’s lived with diabetes for more than 53 years now and has faced many challenges. I enjoy his positive attitude and how he continues to charge forth and do what he loves. Over the course of his life, he built an incredible design business. He’s won more than 40 major design awards, and his work has brought him from Chicago̵...

Does your health monitor have device bias?
In recent years, there’s been a veritable explosion in the number and type of health monitoring devices available in smartphones and fitness apps.
Your smartphone is likely tracking the number of steps you take, how far and fast you walk, and how many flights of stairs you climb each day. Some phones log sleep, heart rate, how much energy you’re burning, and even “gait health” (how often are both feet on the ground? how even are your steps?). And, of course, nonphone wearables and fitness gadgets are available, such as devices to measure your heart rhythm, blood pressure, or oxygen levels. The accuracy of these dev...

COVID-19 vaccines are safe for people with severe allergies
The intensive care unit nurse was worried the COVID-19 vaccine would kill her. In the past, just minutes after getting the influenza vaccine, she had hives, wheezing, and throat swelling. Her life-threatening reaction only resolved after an epinephrine injection and monitoring in the emergency room. She vowed never to get another vaccine.

When Will Coronavirus Be Over – 2021 Update
2020 has brought previously unseen challenges upon humankind. A virus that, due to globalisation, spread at an unprecedented speed, stormed the entire planet and there is only one thing that can stop it as it is now: a vaccine. And as I wrote in The Medical Futurist vaccine pledge, if you worry about the long-term consequences (which no data indicate for now after having tested the vaccine on tens of thousands of people and vaccinating already millions), you might want to wait out. But then we’ll be in lockdown for years.
Over the past year several lockdowns have taken place. We adopted new habits, learned and worked ...

A little less nervous about Covid
The rare and potentially lethal neurological disorder, Guillain-Barré syndrome, is not triggered by Covid nor by vaccination against Covid, recent research suggests.
There was concern during the early months of the Covid pandemic based on anecdotal evidence that there had been an increase in the incidence of a potentially lethal neurological disorder known as Guillain-Barré syndrome (GBS). In this disease, the body’s own immune system attacks peripheral nerves causing numbness, pain, and paralysis. It can be fatal if not treated promptly.
Pain and numbness often spread upwards from the soles of the feet or the hand...
