The FLiRT variant KP.2 begins its takeover for Covid cases in the US, now accounting for 1 in 4 cases

I've reviewed the FLiRT variants and their implications in a Ground Truths (link in profile) Image
The 2 mutations in the spike that account for KP.2's rise to dominance, compared with the JN.1 variant which has prevailed for months Image

Breaking down the risks and benefit for lecanemab, the amyloid beta-directed antibody vs Alzheimer's drug approved @US_FDA last year. It doesn't look good.

A new systematic review of these antibodies looks even worse @AnnFamMed doi.org/10.1370/afm.30…

My oped on the JN.1 variant and the 2nd biggest US wave of infections (after Omicron) since the pandemic began
@latimes @latimesopinion #LongCovid latimes.com/opinion/story/…

Recent @CDCgov #SARSCoV2 wastewater data for current wave (vs Omicron Jan 2022 and subsequent waves), graph by @luckytran Image
Sorry, @washingtonpost, but this is not "another Covid-19 uptick" as you put it in your Health Alert. You ignore the best metric for infections that we have at present—wastewater—focusing only on hospitalizations

3 New #LongCovid reports
1. Vaccination protection—1 dose 21%, 2 doses 59%, 3 doses 73% among ~590,000 people in Sweden (strong association)
bmj.com/content/383/bm…

2. 3-year prospective follow up of a cohort of ~1350 participants, hospitalized in China
—Lung function restored back to baseline in most
—Higher risk of reinfection that people w/o Long Covid
—Half w/ persistent symptoms

3. At @RSNA annual meeting, brain MRI with microstructure imaging (DMI), participants with #LongCovid vs controls had microstructure changes associated with impaired cognition, sense of smell and fatigue

Big news #ESC2023 and @NEJM
In a placebo-controlled randomized trial of people with obesity + heart failure (with preserved ejection fraction). semaglutide (Wegovy) markedly improved symptoms, exercise time, reduced inflammatory markers (and weight loss)
nejm.org/doi/full/10.10…

Image

This also tells us something about the underlying mechanism of heart failure with preserved EF—metabolic dysfunction and attendant systemic inflammation—not previously acknowledged or confirmed
The accompanying editorial lays this finding out well. Prior studies of weight loss didn't help HFpEF

Two new papers @NatureMedicine and @JAMAInternalMed shed light on #LongCovid at 2-years. But there's no shortage of known unknowns.
