What I believe was surprising was that how much a single bacteria species is explaining (and predicting) a single food item (coffee), among all the complexities we have in microbiome studies. And these predictions were not presence/absence but rather with relative abundance values. (2/2)

Thanks Gabriele for your interest in our work. Indeed, we don't really go into the clinical/medical relevance of Lawsonibacter here. (1/2)

Gut microbiome signatures of vegan, vegetarian and omnivore diets and associated health outcomes across 21,561 individuals - Nature Microbiology Using 21,561 individuals, the authors present a cross-sectional study of how gut microbiome signatures are associated with dietary intake patterns and with host health outcomes.

🧵 How does being a #vegan, #vegetarian or omnivore impact your gut #microbiome? 🥦 Find out in our new paper on gut microbiome signatures of vegan, vegetarian & omnivore diets & associated health outcomes across 21,561 individuals in @naturemicrobiol.bsky.social!🎉 1/10

Ciao @mikeneugent.bsky.social from the both us! (unfortunately mine is from the vending machine, the fastest one I could get here!)

This is figure 1, which shows the consistent global links between coffee consumption and the human gut microbiome.

Coffee consumption is associated with the presence and abundance of a specific member of the human gut microbiome, Lawsonibacter asaccharolyticus, and changes to the plasma metabolome, according to a paper in Nature Microbiology. https://go.nature.com/3CIl4as 🧪

Fantastic event in Goiania! Beautiful audience and nice people! Had a great time, thanks Joao for the invitation and all the organizers for the organization!

Would love to be included if possible, thanks a lot

Be aware of common pitfalls when using ML in microbiological studies (Box 2) and hopefully, the simplified checklist when reading, reviewing, or applying ML (Box 3) can help in better understanding the best strategies to use and their evaluation.

6/6

Be careful of overfitting, feature selection and testing within the same data, which could lead to overoptimistic within-dataset and poor performances cross-cohorts.

5/6

Several strategies are available to accurately estimate ML performances and depend and the data/cohorts availability.

4/6

Dimensionality reduction and clustering are two of the most used algorithms in microbiology, and different algorithms will have different results and visualization of high-dimensional data is also a non-easy task.

3/6

A ML workflow involves many small details: difficult to represent in a simplified schema as most are also algorithm-dependent. However, having a clear idea about the process can better help understand how several steps (samples, features, training, prediction) connect.

2/6

I'm thrilled to share our team's effort towards enabling ML usage and evaluation for microbiologists. Here goes the summary thread 🧵
