Air and Water Processes Do Not Produce the Same High-Quality Pasteurization of Donor Human Milk / Rachel Buffin in Journal of Human Lactation, Vol. 33, n°4 (Novembre 2017)

[article]  inJournal of Human Lactation > Vol. 33, n°4 (Novembre 2017) . - pp. 717–724 Titre : Air and Water Processes Do Not Produce the Same High-Quality Pasteurization of Donor Human Milk Type de document : texte imprimé Auteurs : Rachel Buffin, Auteur ; Pierre Pradat, Auteur ; Jocelyne Trompette, Auteur Année de publication : 2017 Article en page(s) : pp. 717–724 Langues : Anglais (eng) Catégories : Composition du lait Lactarium Lait maternel pasteurisé Pasteurisation Résumé : This study aimed to assess the detailed pattern of pasteurization temperature using two water pasteurizers (WP1 and WP2) and one air pasteurizer (AP). Human milk treated using the air pasteurizer in our study was exposed to higher temperatures and for longer periods of time than the water pasteurizers we employed. Regular qualification of pasteurizers is requested when evaluating the effect of pasteurization on milk components and for routine treatment of human milk in milk banks.

Ebola Virus and Marburg Virus in Human Milk Are Inactivated by Holder Pasteurization / Erin Hamilton Spence in Journal of Human Lactation, Vol. 33, n°2 (Mai 2017)

[article]  inJournal of Human Lactation > Vol. 33, n°2 (Mai 2017) . - pp. 351-354 Titre : Ebola Virus and Marburg Virus in Human Milk Are Inactivated by Holder Pasteurization Type de document : texte imprimé Auteurs : Erin Hamilton Spence, Auteur ; Monica Huff, Auteur ; Karen Shattuck, Auteur Année de publication : 2017 Article en page(s) : pp. 351-354 Langues : Anglais (eng) Catégories : Composition du lait Pasteurisation Virus Résumé : "Background: Potential donors of human milk are screened for Ebola virus (EBOV) using standard questions, but testing for EBOV and Marburg virus (MARV) is not part of routine serological testing performed by milk banks. Research aim: This study tested the hypothesis that EBOV would be inactivated in donor human milk (DHM) by standard pasteurization techniques (Holder) used in all North American nonprofit milk banks. Methods: Milk samples were obtained from a nonprofit milk bank. They were inoculated with EBOV (Zaire strain) and MARV (Angola strain) and processed by standard Holder pasteurization technique. Plaque assays for EBOV and MARV were performed to detect the presence of virus after pasteurization. Results: Neither EBOV nor MARV was detectable by viral plaque assay in DHM or culture media samples, which were pasteurized by the Holder process. Conclusion: EBOV and MARV are safely inactivated in human milk by standard Holder pasteurization technique. Screening for EBOV or MARV beyond questionnaire and self-deferral is not needed to ensure safety of DHM for high-risk infants."

Effect of Environmental Conditions on Unpasteurized Donor Human Milk / David J. Rechtman in Breastfeeding Medicine, Vol.1, n°1 (Printemps 2006)

We undertook an experiment to measure the effects of ambient temperature conditions and refreezing on the bioburden and nutritional content of human milk. We conclude that unpasteurized human milk is robust and can be used after storage under certain conditions." (Résumé de l'auteur) Permalink : ./index.php?lvl=notice_display&id=538 [article]

Effect of the Various Steps in the Processing of Human Milk in the Concentrations of IgA, IgM, and Lactoferrin / Gerardo Arroyo in Breastfeeding Medicine, Vol 12, n°7 (Septembre 2017)

[article]  inBreastfeeding Medicine > Vol 12, n°7 (Septembre 2017) . - pp.443-445 Titre : Effect of the Various Steps in the Processing of Human Milk in the Concentrations of IgA, IgM, and Lactoferrin Type de document : texte imprimé Auteurs : Gerardo Arroyo, Auteur ; Kevin Alexander Ortiz Barrientos, Auteur ; Karla Lange, Auteur Année de publication : 2017 Article en page(s) : pp.443-445 Langues : Anglais (eng) Catégories : Composition du lait Immunoglobuline Immunoglobuline A Lactarium Lactoferrine Pasteurisation Résumé : "Introduction: Human milk immune components are unique and important for the development of the newborn. Milk processing at the Human Milk Banks (HMB), however, causes partial destruction of immune proteins. The objective of this study was to determine the effects that heating during the milk processing procedure at the HMB had on the concentrations of IgA, IgM, and lactoferrin at three critical points in time. Materials and Methods: Fifty milk samples (150 mL) were collected from voluntary donors at the HMB at the Hospital Nacional Pedro de Bethancourt, located in Antigua Guatemala. Samples from three critical points in time during the milk processing procedure were selected for analysis: freezing/thawing I, freezing/thawing II, and pasteurization. IgA, IgM, and lactoferrin concentrations were determined during each critical point and compared with a baseline concentration. Results: After milk processing, IgA, IgM, and lactoferrin mean concentrations were reduced by 30.0%, 36.0%, and 70.0%, respectively (p < 0.001). Reduction of biological activity was mainly attributed to pasteurization for IgA and lactoferrin (p < 0.001); the first freezing/thawing processes before pasteurization showed no significant reduction difference between mean concentrations of IgA (p = 0.160) and lactoferrin (p = 0.345) but showed a significant effect on IgM concentration (p = 0.016), and the second freezing/thawing procedure only showed a significant effect on IgA (p < 0.001). Conclusions: The effects of milk processing on the immune proteins that were evaluated in this study demonstrated a significant reduction."[résumé de l'auteur] Permalink : ./index.php?lvl=notice_display&id=803 [article]

From royal wet nurses to Facebook: The evolution of breastmilk sharing / Kelley L Baumgartel in Breastfeeding Review, Vol. 24, n°3 (Novembre 2016)

[article]  inBreastfeeding Review > Vol. 24, n°3 (Novembre 2016) . - pp. 25-32 Titre : From royal wet nurses to Facebook: The evolution of breastmilk sharing Type de document : document cartographique imprimé Auteurs : Kelley L Baumgartel, Auteur ; Larissa Sneeringer, Auteur ; Susan M Cohen, Auteur Année de publication : 2016 Article en page(s) : pp. 25-32 Langues : Anglais (eng) Catégories : 19e siècle 20e siècle 21e siècle Antiquité Histoire Histoire de l'allaitement Moyen-Âge Nourrice allaitante Pasteurisation Période Contemporaine (De 1789 à aujourd'hui) Pratique de l'allaitement Résumé : Wet-nursing was an essential practice that allowed for infant survival after many mothers died in childbirth. The story of wet-nursing is complicated by both religious pressures and cultural expectations of women.It is likely that these historical practices have shaped our current social, political and legislative environments regarding breastfeeding. The aim of this article is to provide a historical perspective on the practice of wet-nursing, with a focus on: 1) social views of wet nurses, 2) breastmilk evaluation and 3) the ideal wet nurse. Historical perspective from Ancient Egypt, Ancient Greece and Rome, 19th and 20th century America and current practices are examined. An appreciation for the evolution of breastmilk sharing provides clinicians and lactation advocates with the historical origins which provided the template for current practice as it relates to donor milk, breastfeeding culture and relevant legislation.
