From the Omicron front, Bloomberg’s Prognosis informs us that

The coronavirus that causes Covid-19 can spread within days from the airways to the heart, brain and almost every organ system in the body, where it may persist for months, a study found.

In what they describe as the most comprehensive analysis to date of the SARS-CoV-2 virus’s distribution and persistence in the body and brain, scientists at the U.S. National Institutes of Health said they found the pathogen is capable of replicating in human cells well beyond the respiratory tract.

The results, released online Saturday in a manuscript under review for publication in the journal Nature, point to delayed viral clearance as a potential contributor to the persistent symptoms wracking so-called long Covid sufferers. Understanding the mechanisms by which the virus persists, along with the body’s response to any viral reservoir, promises to help improve care for those afflicted, the authors said.

An opinion piece in STAT News discusses a trend in COVID weekly new death statistics in the U.S. that the FEHBlog noticed in last Thursday’s post:

Several colleagues and I [Duane Schulthess] at Vital Transformation began closely following the data on Covid-19 early in the pandemic.

Since that time, we’ve kept a keen eye on the relationship between cases and deaths, particularly during the recent waves, which have been influenced by improved treatments and vaccines, as well as by new variants. There are legitimate concerns about the trajectory of the newest variant, Omicron, and public health experts are paying close attention to the exponentially mounting cases, particularly in the United Kingdom, which in the past has functioned as a canary in the Covid-19 coal mine for the U.S.

While early reports from South Africa suggested that Omicron might cause less-severe Covid-19, the rapidly mounting case numbers and overall transmissibility have been alarming, particularly in the U.K. According to a Dec. 10 government technical briefing(see page 17), Omicron cases were expanding by 35% per day.

But there’s something else different this time around, at least in the U.K.: the statistical relationship between Covid-19 cases and deaths appears to have broken down with Omicron.

Looking at daily death rates in the U.K. from May 15 — essentially from the point at which the Delta wave began — to Sept. 15, there is a highly statistically significant relationship between daily new cases and deaths. In short, case rates accurately predict death rates. But beginning the analysis on Sept. 15, coinciding with flattening of the Delta curve and the onset of Omicron, shows no statistical relationship between Covid-19 case rates and deaths. * * *

It’s still, of course, early days. While it is possible that death rates due to Omicron may rise later, at the moment in the U.K., Covid-19 daily cases no longer meaningfully link to deaths. So, according to the math, Omicron cases rising no longer automatically means impending doom and gloom

In healthcare M&A news, Healthcare Dive tells us that

— Tenet and its subsidiary USPI completed a $1.1 billion acquisition of SurgCenter Development, giving the ambulatory surgery unit an ownership stake in 86 more surgery centers and related support services.

— Tenet said it’s willing to buy additional interests of up to $250 million from physician owners. This process is expected to continue over the coming months, Tenet said Wednesday.

— As part of the deal, USPI will have exclusivity on developing new centers — at minimum 50 — with SCD during a five-year period.

From the FDA new drug approval front, MedCity News reports that

The FDA has approved a new cholesterol-lowering drug from Novartis that addresses the same target as two commercialized medicines from Amgen and Regeneron, but with a different approach and a key dosing advantage—just two injections per year.

The drug, inclisiran, is part of a relatively new class of genetic medicines that work by stopping production of a problem protein. In the case of the Novartis drug, which will be marketed under the name Leqvio, the target is PCSK9, a liver protein that in high amounts, impedes the body’s ability to clear low-density lipoprotein cholesterol, the “bad” form of cholesterol. Leqvio is comprised of small-interfering RNA that harnesses a cellular mechanism called RNA interference to stop a gene from producing PCSK9.

The way that Leqvio and other RNAi drugs work is sometimes referred to as gene silencing. It’s a different approach than PCSK9 inhibitors, antibody drugs that bind to this protein to block it. The FDA approved two of these drugs, Amgen’s  Repatha and Regeneron’s Praluent, in 2015. They’re both given as subcutaneous injections every two weeks or monthly. However, their high price tags made them a tough sell to payers, and revenue fell short of initial expectations. In 2018, Amgen slashed Repatha’s price by nearly 60%, making the drug available at list price of $5,850 per year. Months later, Regeneron matched the pricing move for its PCSK9-blocking drug.

The benefits of competition do apply to prescription drug development.

Last week, the U.S. Census Bureau released its “Vintage 2021 national and state population estimates and components of change.” In sum,

Since April 1, 2020 (Census Day), the nation’s population increased from 331,449,281 to 331,893,745, a gain of 444,464, or 0.13%.

Between July 1, 2020, and July 1, 2021, the nation’s growth was due to natural increase (148,043), which is the number of excess births over deaths, and net international migration (244,622). This is the first time that net international migration (the difference between the number of people moving into the country and out of the country) has exceeded natural increase for a given year.

The voting-age resident population, adults age 18 and over, grew to 258.3 million, comprising 77.8% of the population in 2021.

The South, with a population of 127,225,329, was the most populous of the four regions (encompassing 38.3% of the total national population) and was the only region that had positive net domestic migration of 657,682 (the movement of people from one area to another within the United States) between 2020 and 2021. The Northeast region, the least populous of the four regions with a population of 57,159,838 in 2021, experienced a population decrease of -365,795 residents due to natural decrease (-31,052) and negative net domestic migration (-389,638).

The West saw a gain in population (35,868) despite losing residents via negative net domestic migration (-144,941). Growth in the West was due to natural increase (143,082) and positive net international migration (38,347).
