1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Despite the early recognition that individuals living with obesity are more prone to develop adverse outcomes during COVID-19, the mechanisms underlying these conditions are still unclear. During obesity, an accumulation of free fatty acids (FFAs) in the circulation promotes low-grade inflammation. Here, we show that FFAs induce epigenetic reprogramming of monocytes, exacerbating their inflammatory profile after SARS-CoV-2 infection, a mechanism named metabolic-primed immunity. Monocytes from people with obesity or primed with palmitate, a central component of circulating FFAs, presented elevated viral load and higher gene expression of IL-6. Palmitate-primed monocytes upregulate fatty acid oxidation and FFAs entry into the mitochondria. FFA-derived acetyl-CoA is then converted into citrate, exiting the mitochondria and is used to support H3K18 histone acetylation, which regulates IL-6 accessibility. Ingestion of palm oil by lean and healthy individuals increased circulating FFAs levels and was sufficient to exacerbate the inflammatory profile of monocytes upon SARS-CoV-2 infection. Our findings demonstrate that obesity-derived FFAs induce the metabolic priming of monocytes, which exacerbates the inflammatory response observed in people with severe COVID-19.
