1/ 🚨 Sarcopenia is the loss of muscle strength, mass & function, worsened by chronic illness like CVD, kidney disease, & cancer 😷🩺
2/ 👴👵 Older adults face higher risks: faster CVD progression, mortality, falls, & reduced quality of life 📉

Though not its intention, this study from #OW2022 illustrated the concepts of satiation vs satiety very well
Colloquially we use these terms interchangeable
But they are technically different

Satiation is the feeling of fullness WITHIN a meal while satiety is the feeling of fullness IN BETWEEN meals
Even though current meds like GLP1s seem to affect both, it’s an impt distinction especially when some peptides (eg, amylin)

may only effect satiation (⬇️meal size) and not satiety (change meal frequency)
[btw This study was an intracerebral injection of calcitonin into male rats and calcitonin is an agonist at the amylin receptor in the ventral tegmental area]

First, what do you think is the predominant mechanism by which thrombosis occurs in COVID-19?
Where does thrombosis typically first occur?

First, let’s briefly summarize what we covered before:
What mechanism may be partly responsible for heterogeneity of COVID-19 disease phenotype as well as its severity?
What mechanism may be partly responsible for heterogeneity of COVID-19 disease phenotype as well as its severity?
Correct! Antibody-dependent enhancement (ADE) is the result of producing sub-neutralizing antibodies which paradoxically enhance the rate of viral replication and severity of viremia.

What do #COVID-19 and #Dengue fever potentially have in common?
The answers have significant potential clinical implications in COVID-19.
Buckle up. It's a long one.

Dengue is a flavivirus that is called “breakbone fever”, a nod to bone-breaking pains that occur during the infection.
There are four serotypes of the dengue virus.
Infection with one serotype does not fully protect one from contracting a different serotype.
There are four serotypes of the dengue virus.
Infection with one serotype does not fully protect one from contracting a different serotype.
True or false: The second or later infection with dengue is often much more dangerous.

You say of course and see the patient. 🥼🩺His BP was 131/87 mmHg with a HR of 142 bpm. He was fatigued, but AOx3. Moist mucous membranes, normal skin turgor, and no LE edema.
