Electrochemical aptasensor for the selective detection of vancomycin based on nanostructured "in-lab" printed electrodes.
Mikrochim Acta

Department of Analytical Chemistry, Faculty of Pharmacy, "Iuliu Hațieganu" University of Medicine and Pharmacy, 4 Pasteur Street, 400349, Cluj-Napoca, Romania.
A label-free, flexible, and disposable aptasensor was designed for the rapid on-site detection of vancomycin (VAN) levels. The electrochemical sensor was based on lab-printed carbon electrodes (C-PE) enriched with cauliflower-shaped gold nanostructures (AuNSs), on which VAN-specific aptamers were immobilized as biorecognition elements and short-chain thiols as blocking agents. The AuNSs, characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM), enhanced the electrochemical properties of the platform and the aptamer immobilization active sites.

Background: Human milk banks (HMBs) offer the best feed for neonates after mother's own milk (MOM), especially when MOM is insufficient. Although HMBs are founded on standard protocols, contamination and wastage of milk due to positive milk cultures remain a problem. Present study was planned as a quality improvement (QI) initiative to reduce culture rates at the HMB.

Background: Whilst it is inconvenient and time-intensive, predominantly (PP) and exclusively pumping (EP) mothers rely on breast expression to provide milk for their infants and to ensure continued milk supply, yet these populations are poorly understood.
Methods: We assessed and characterised Western Australian PP mothers ( = 93) regarding 24 h milk production (MP) and infant milk intake and demographics, perinatal complications and breastfeeding difficulties, the frequencies of which were compared with published general population frequencies. Pumping efficacy and milk flow parameters during a pumping session in PP mothers ( = 32) were compared with those that pump occasionally (reference group, = 60).
A Pilot Study Exploring the Relationship Between Milk Composition and Microbial Capacity in Breastfed Infants.

Background: Maternal obesity may contribute to childhood obesity in a myriad of ways, including through alterations of the infant gut microbiome. For example, maternal obesity may contribute both directly by introducing a dysbiotic microbiome to the infant and indirectly through the altered composition of human milk that fuels the infant gut microbiome. In particular, indigestible human milk oligosaccharides (HMOs) are known to shape the composition of the infant gut microbiome.

Pediatric Epidemiology, Department of Pediatrics, Medical Faculty, Leipzig University, Liebigstr 20a, Haus 6, 04103 Leipzig, Germany.
Background/objectives: Although approximately 160 human milk oligosaccharides (HMOs) have been identified, current studies on HMO quantitation are limited to the 10-19 most abundant HMOs. We assessed the variations in the relative concentrations of 71 HMO structures over lactation in human milk samples by an advanced liquid chromatography-mass spectrometry approach.
Methods: Samples were collected from 64 mothers at 6 weeks, 6 months, and 12 months of lactation in the Ulm SPATZ Health Study, a German birth cohort.
