Background: This study examines the influence of prematurity and diabetes (DM) in pregnancy on metabolite patterns at birth, and associations with adiposity development in a prospective cohort.
Methods: Term and preterm (30-36 weeks gestational age [GA]) infants were enrolled and body composition assessments completed through discharge. Targeted metabolomics was used to assess metabolites in cord or infant blood in the first 2 days.
Results: Among 91 infants, 62 were preterm and 27 were exposed to DM. In factor analysis, variation in acylcarnitines' and non-essential amino acids differed by GA and DM exposure and were associated with adiposity at term age. DM-group had 1.95-fold increase in t4-OH-pro (p = 0.003) and 2.14-fold increase in taurine (p = 0.004) compared with non-DM group. Preterm infants had 1.77-fold increase in glycerophospholipid PC aa C32:2 versus term group (p < 0.001). Pathway analysis revealed differences across DM and GA groups in pathways associated with citrulline metabolism, amino acid transport/ synthesis, and fatty acid quantity/transport.
Conclusion: In this cohort of infants, there are unique metabolite signatures associated with DM exposure, prematurity, and adiposity development after birth. These markers may reflect early metabolism changes in the developing infant which relate to known risks of adverse growth and cardiometabolic outcomes in this group.
Impact: In this study of term and preterm infants, diabetes in pregnancy was associated with unique metabolic signatures at birth, including increased expression of metabolites related to protein synthesis and lipid metabolism. Metabolites related to lipid and protein metabolism were associated with adiposity development at term age, including estimated body fat percent, skin fold thickness measures, and arm circumference measures. Unique signatures of metabolites associated with prematurity and exposure to diabetes in pregnancy may reflect early metabolism changes in the developing infant which relate to known risks of adverse growth and cardiometabolic outcomes in this group.

Chronic kidney disease (CKD) is a global health challenge associated with lifestyle factors such as diet, alcohol, BMI, smoking, sleep, and physical activity. Metabolomics, especially nuclear magnetic resonance(NMR), offers insights into metabolic profiles' role in diseases, but more research is needed on its connection to CKD and lifestyle factors. Therefore, we utilized the latest metabolomics data from the UK Biobank to explore the relationship between plasma metabolites and lifestyle factors, as well as to investigate the associations between various factors, including lifestyle-related metabolites, and the latent phase of CKD onset.

Pinus pinaster Aiton (maritime pine) stands are suffering a generalized deterioration due to different decline episodes throughout all its distribution area. It is well known that external disturbances can alter the plant associated microbiota and metabolome, which ultimately can entail the disruption of the normal growth of the hosts. Notwithstanding, very little is known about the shifts in the microbiota and the metabolome in pine trees affected by decline.

The increasing shift from cannabis smoking to cannabis vaping is largely driven by the perception that vaping to form an aerosol represents a safer alternative to smoking and is a form of consumption appealing to youth. Herein, we compared the chemical composition and receptor-mediated activity of cannabis smoke extract (CaSE) to cannabis vaping extract (CaVE) along with the biological response in human bronchial epithelial cells. Chemical analysis using HPLC and GC/MS revealed that cannabis vaping aerosol contained fewer toxicants than smoke; CaSE and CaVE contained teratogens, carcinogens, and respiratory toxicants.

Because the liver plays a vital role in the clearance of exogenous chemical compounds, it is susceptible to chemical-induced toxicity. Animal-based testing is routinely used to assess the hepatotoxic potential of chemicals. While large-scale high-throughput sequencing data can indicate the genes affected by chemical exposures, we need system-level approaches to interpret these changes.
