Skin examination reveals a dark pigmented irregular lesion R anterior shin. Noticed for the first time after a morning of yard work. Previous dermatology history includes a large Becker’s nevus L scapula, several small hematomas, multiple mocha colored age spots and solar keratoses. Patient has never consulted Dermatology and has never been followed medically for his Becker’s nevus. No family history of skin cancers.

Micro-clots and long COVID (it’s a hypothesis people)

But many hematologists and COVID-19 researchers worry that enthusiasm for the clot hypothesis has outpaced the data. They want to see larger studies and stronger causal evidence. And they are concerned about people seeking out unproven, potentially risky treatments.

This is a good article on the micro-clot hypothesis behind long Covid.

What do we know about Covid-19 vaccines in under 5s?

How researchers and public health officials perceive the risk-benefit ratio of rolling out vaccines to under 5s varies around the world and depends on the impact covid-19 has had on that country. Sweden has had just a handful of fatalities in those aged under 18,6 and vaccines are still not available to children aged 5-11 years. But in Brazil the virus has killed an average of two children under the age of 5 each day7—a rate which equates to around one in every five deaths among under 5s worldwide. Understandably, doctors are keen to boost protection levels, fearful of the impact that future variants might have.

Covid-19: is omicron less lethal than delta?

This study provides the most conclusive evidence to date that infection with the omicron subvariant BA.1 was inherently less deadly than delta when controlling for a number of key covariates. Combining death certification records with molecular surveillance is the main advantage of this study, which avoids previous biases in covid-19 death designations. Accounting for a broad array of standardised covariates, including sociodemographic variables, pre-existing health conditions, and previous immunity, is another strength.

Where Have All the Briskets Gone?

The question now is how quickly the supply from the beef processors will stabilize to bring overall beef prices down and live cattle prices up. U.S. Secretary of Agriculture Sonny Perdue announced this week that he expected all the processing plants to be reopened soon. “I’d say probably a week to ten days we’ll be back up, fully back up,” Perdue said in a meeting with Trump and Iowa governor Kim Reynolds, but that may be overly optimistic. Even if the plants have reopened, they won’t likely be at full capacity. As David Anderson from Texas A&M says, “It doesn’t mean anybody’s going to show up,” referring to the workers. In an anonymous essay, an employee who says she works at a Tyson beef plant in Amarillo wrote: “I don’t feel critical. I don’t feel essential. I feel sacrificial.” Even if the workers are willing to return to the reopened plants, USDA inspectors are required for any plant to operate, and more than one hundred members of the already short-staffed inspector workforce have been infected.

What Retirement?

Coronavirus Shock Is Destroying Americans’ Retirement Dreams

For older people, the coronavirus crisis has been an appalling shock. Many can’t travel or see grandchildren. Even buying groceries is a risk. Their life savings are melting as the global economy shuts down and financial markets plummet. The pain may be particularly acute in the U.S., where Americans rely on a retirement system that was broken well before a pandemic dashed it to pieces.
