A lot of what looks like microbial engraftment after FMT might actually be noise. Using placebo sequencing and culture-enriched metagenomics, we sort signal from noise. Our latest from the Surette lab: www.nature.com/articles/s41... @surettem.bsky.social @mcmasteruniversity.bsky.social

Here, the authors profile bacterial engraftment in UC patients receiving FMT from a single donor and placebo samples to estimate noise, showing a significant level of false-positive engraftment, which...

Donor/recipient exchange, which includes transplanted tissue (bone marrow, organs) or even just blood received in transfusion from a donor. We can even use this microchimerism to monitor engraftment of organs, by measuring each marker in blood draws from the recipient.

an average of 2.7 severe hypoglycemic episodes in the year prior to screening. All participants had engraftment and infusion, as detected by the appearance of C-peptide. Two patients received a half dose of zimislecel, and 12 received a full dose (0.8 × 109 cells) in a single infusion. So, what did

Niche-preserving transplantation promotes functional engraftment of intestinal organoids in rat short bowel syndrome
Endo et al. show that preserving the intestinal niche enables near-complete engraftment of ileal organoids in the jejunum. The resulting ilealized segment restores bile acid absorption and improves survival in short bowel syndrome, suggesting a path toward region-targeted, autologous regenerative therapy.

Sugar-rich foods exacerbate antibiotic-induced microbiome disruption
In this cohort study of adult allo-HCT recipients at Memorial Sloan Kettering Cancer Center in New York between 2017 and 2022, eligible participants had been admitted for Allo-HCT. Three times weekly, patients who had been recently admitted for allo-HCT were invited to participate in dietary-intake collection. Neutrophil engraftment was defined as the first of 3 days of neutrophil count ≥500 per μl. Five patients died without achieving engraftment and were excluded from the analysis of median time to engraftment. No patients were lost to follow-up. For mortality analysis, one patient died before landmark day 12 and was excluded from that analysis. The latest follow-up/data collection date was in April 2023. Nutrition data collection and annotation The hospital kitchen commercial computer system (Computrition) was configured to provide a printout that accompanied each meal tray to the bedside on which patients were asked to indicate, immediately after each meal, whether they consumed 0, 25%, 50%, 75% or 100% of each item they ordered for that meal. These instruments were collected by a dietician or other research team members three times weekly, during which missing entries were completed at the bedside along with encouragement to sustain motivation with the project. Consumption data were...

Next, we explored a larger number of prebiotic and dietary contexts for the probiotic cocktail, across a larger number of people (156 from the Arivale cohort). We saw variable engraftment, depending on the diet. A. muciniphila always engrafted in the presence of a vegan high fiber diet.
