Improved Method for Calculating Medication Exposure Trajectories in Pregnancy Studies
Researchers developed an adjusted method for calculating medication exposure trajectories that accounts for the number of dispensed medication packs and whether medications were taken occasionally or regularly. Testing on the EFEMERIS database showed that while 65% of exposure trajectories remained unchanged, the remaining cases showed significant differences in dosage calculations and exposure profiles. The refinement improved clustering quality and revealed associations between high psychotropic medication exposure during pregnancy and increased neonatal pathology.
A research team presented a methodological advancement for measuring medication exposure during pregnancy by incorporating the number of dispensed packs and periodicity of dispensations into trajectory calculations. Using data from the EFEMERIS database, they compared three different calculation scenarios to assess the impact of including these factors. The analysis revealed that while most trajectories (65%) remained stable across scenarios, the remaining cases showed meaningful changes in Defined-Daily Dose (DDD) calculations and individual exposure profiles. The adjusted method improved the quality of clustering women into exposure groups, with 4% of cases reassigned to different clusters. The study found that neonates born to mothers in the high-dose psychotropic medication cluster showed higher rates of pathology, supporting previous research linking elevated psychotropic exposure during pregnancy to adverse neonatal outcomes.
What's missing
The study does not discuss potential limitations of the EFEMERIS database itself, the specific types of neonatal pathologies observed, or whether the findings have been validated in independent datasets beyond EFEMERIS.

Gut Bacteria Enzyme Found to Break Down Heat-Processed Food Compounds, Producing Novel Biogenic Amines
Researchers have discovered that an enzyme in common gut bacteria can degrade N-epsilon-carboxymethyllysine (CML), a compound formed during thermal food processing, producing previously unknown biogenic amines. The enzyme, ornithine decarboxylase SpeC from enterobacteria, acts on CML and related modified lysine derivatives through a low-level 'underground' catalytic activity. This finding suggests a previously unrecognized communication axis between thermally processed dietary compounds and gut microbial physiology, with potential implications for host health.
Full-Length Gene Sequencing Reveals Two Distinct Bacterial Communities in Black-Legged Ticks Expanding Into Canada
Researchers used Oxford Nanopore full-length 16S rRNA gene sequencing to characterize the microbiome of Ixodes scapularis black-legged ticks collected in Nova Scotia, Canada, distinguishing between tick-adapted bacteria and environmentally acquired bacteria. The study comes as I. scapularis — the primary vector of Lyme disease — is rapidly expanding northward into Canada due to climate change. The findings suggest that environmentally derived bacteria in tick microbiomes are not mere contamination, which has implications for how tick microbiome data is collected and interpreted across surveillance studies.
Study Identifies Metabolic Link Between Cell Envelope Stress and Biofilm Formation in Bacteria
Researchers have discovered that the metabolite acetyl-CoA directly inhibits enzymes that degrade the bacterial signaling molecule c-di-GMP, connecting cell envelope biosynthesis stress to biofilm formation in Pseudomonas aeruginosa. The study found that sub-inhibitory concentrations of antibiotics targeting early peptidoglycan biosynthesis — but not other antibiotic classes — elevate c-di-GMP levels by reducing phosphodiesterase activity, with acetyl-CoA competing for the enzyme active site. Because the relevant enzyme domain is broadly conserved across bacterial species, this checkpoint mechanism may be widespread and could have implications for understanding antibiotic-induced biofilm responses.
