Two 9-week-old, breast-fed premature infants developed acrodermatitis and hypozincemia because of low zinc content in their mothers' breast milk. All symptoms of zinc deficiency disappeared within seven days after the infants were treated orally with zinc and did not recur when zinc was discontinued after 11 months (infant 1) and three weeks (infant 3). After a subsequent term pregnancy, one of the mothers had lower breast milk zinc content (P less than .025) and greater exponential decline (P less than .025) of zinc content through 40 weeks of lactation compared with 34 control subjects. Her second infant (infant 2) had hypozincemia at 7 months of age but did not develop clinical zinc deficiency. When the mothers of the affected infants took oral zinc supplements, there was no increase in their breast milk zinc content. Zinc secretion into breast milk appears to be a controlled process that is independent of maternal zinc intake or serum zinc level. Breast milk may be low in zinc because of defective mammary secretion and this may lead to severe symptomatic zinc deficiency in premature infants.

Human breast milk-derived exosomes and their positive role on neonatal intestinal health.

Although the role of breast milk in promoting neonatal growth and maintaining intestinal homeostasis is well established, underlying mechanisms by which it protects the intestine from damage remain to be elucidated. Human breast milk-derived exosomes (HMDEs) are newly discovered active signaling vesicles with a diameter of 30-150 nm, which are key carriers of biological information exchange between mother and child. In addition, due to their ability to cross the gastrointestinal barrier, low immunogenicity, good biocompatibility and stability, HMDEs play an important role in regulating intestinal barrier integrity in newborns.

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.

Introduction And Importance: Accessory breast is a rare condition where regression of the mammary ridge fails. This ectopic breast can function as the same pectoral breast and respond to hormonal effects. Furthermore, in rare cases, it can develop into malignancy.

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).
