Determination of cefuroxime in breast milk by LC-MS/MS using SALLME technique
In this study, we aimed to develop the LC-MS/MS method using salt-assisted liquid-liquid micro-extraction (SALLME) for the determination of cefuroxime in breast milk. The method was validated according to the European Medicines Agency (EMA) guidelines. Cefuroxime and the internal standard cefixime were extracted from plasma by a SALLME technique. The results obtained from the entire validation study are at an acceptable level according to the EMA criteria. The calibration curve of cefuroxime was between 25 and 1000 ng/ml, with correlation coefficients of >0.99. The lower limit of quantitation was 25 ng/ml for cefuroxime...

Occurrence, Source and Dietary Exposure of Toxic and Essential Elements in the Indian Food Basket
In this study, representative urban and peri-urban Indian food baskets have been studied for the presence of toxic and essential elements. The concentration of target toxic and essential elements was used to estimate dietary intakes (EDIs) and health risks. Across all food matrices, toxic elements like Cd and Pb were dominant. The highest concentrations of the target elements were found in vegetables, with Cd, Pb, and Ni being beyond permissible limits of the Food and Agriculture Organization of the United Nations and the World Health organization (0.05 mg/kg, 0.1 mg/kg, and 1.5 mg/kg, respectively) in okra, spinach, and c...

Conserved covarying gut microbial network in preterm infants and childhood growth during the first 5 years of life: a prospective cohort study
CONCLUSIONS: Preterm-born children possess a conserved and distinct covarying microbiota during very early life, which may have a profound influence on their growth later in life.TRIAL REGISTRATION NUMBER: NCT03373721 URL OF REGISTRATION: https://clinicaltrials.gov/ct2/show/NCT03373721.PMID:37517614 | DOI:10.1016/j.ajcnut.2023.07.019

Polybrominated diphenyl ether (PBDEs), polychlorinated biphenyls (PCBs), organochlorines pesticides (OCPs) in human breast milk from Colombia: A probabilistic risk assessment approach
Chemosphere. 2023 Jul 22:139597. doi: 10.1016/j.chemosphere.2023.139597. Online ahead of print.ABSTRACTPolybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) are ubiquitous environmental contaminants. They were produced in relatively large volumes in the last century and are now subject to long-term monitoring and regulated under the United Nations Stockholm Convention (SC) on persistent organic pollutants (POPs). Though restricted, human exposure is still a concern and in some regions of the globe the information on the health risk is limited. Sixty breast milk sampl...
