Las proteínas de la leche de vaca pueden causar alergia alimentaria. Los distintos mecanismos de acción involucrados y la variabilidad clínica según la etapa de la vida pediátrica en la que se manifieste ocasionan dificultades en su abordaje, con riesgo de sub- o sobrediagnóstico. En este proceso, intervienen profesionales de diversas áreas y es recomendable su interacción. Es por ello que el objetivo de este consenso ha sido reflejar el conocimiento actualizado desde la interdisciplina, generando recomendaciones para su correcto diagnóstico. Hemos trabajado con el método de Delphi para sumarle a la evidencia científica, la experiencia proveniente de neonatólogos, pediatras, especialistas en alergia, nutrición y gastroenterología. Pensamos que este enfoque interdisciplinario de trabajo va a resultar de utilidad práctica y promoverá una atención más integral de estos pacientes.
Cow's milk protein can cause food allergy. The different mechanisms of action involved, the clinical variability depending on the stage of pediatric life in which it manifests, leads to difficulties in its approach, with the risk of under- or over-diagnosis. Professionals from various areas intervene in this process and their interaction is recommended. That is why the objective of this consensus has been to reflect the updated knowledge in an interdisciplinary mode, generating recommendations for its correct diagnosis. We have worked with the Delphi method to add to the scientific evidence, the experience from neonatologists, pediatricians, experts in allergy, nutrition and gastroenterology. We think that this interdisciplinary approach will be of practical use and will promote more comprehensive care for these patients.

Objective:To compare the short-term outcomes of very low birth weight (VLBW) and extremely low birth weight (ELBW) infants supplementarily fed with fortified donor human milk (DHM) or preterm formula (PF) when the mother's own milk (MOM) is insufficient.Methods:This retrospective cohort study included 91 VLBW or ELBW preterm infants with birth weight<1 500 g who were hospitalized in Peking Union Medical College Hospital from October 1, 2017, to September 30, 2020. Based on the supplemental feeding method when MOM was insufficient, these infants were divided into the DHM group ( n=51) and PF group ( n=40). Mann-Whitney U, t-test, Chi-square test, or Fisher's exact test were used to compare the short-term clinical outcomes during hospitalization between the two groups. Results:(1) There were no statistically significant differences between the 91 preterm infants in the DHM group and PF group in their gestational age, birth weight, sex ratio, birth mode, mothers' age at delivery, or the proportion of infants of small gestational age (all P>0.05). (2) The feeding volume in the DHM group was significantly greater than that in the PF group on the 14th day after birth [(108.2±53.1) vs. (81.0±47.8) ml/(kg·d), t=0.78, P=0.020]. Moreover, the time to achieve the feeding amounts up to 120 ml/(kg·d) and 150 ml/(kg·d) for infants in the DHM group were significantly shorter than those in the PF group [(17.5±10.2) vs. (30.0±12.0) d, t=4.38; (22.1±13.3) vs. (32.3±11.9) d, t=0.02; both P<0.05]; (3) Lower proportion of peripherally inserted central catheter (PICC) [58.8% (30/51) vs. 100% (40/40), χ 2=21.88, P<0.001] and shorter PICC duration were observed in the DHM group [10.0 (0.0-19.0) vs. 29.0 (17.0-40.5) d, Z=5.56, P<0.001] compared to the PF group. The times of red blood cell transfusions and the incidence of late sepsis in the DHM group were less than those in the PF group [0.0 (0.0-2.0) vs. 2.0 (1.0-3.0) times, Z=4.44, P<0.001; 23.5% (12/51) vs. 50.0% (20/40), χ 2=6.39, P=0.011]. There were no statistically significant differences observed in the incidence of bronchopulmonary dysplasia, neonatal necrotizing enterocolitis, retinopathy of prematurity, and the length of hospitalization (all P>0.05). Conclusion:When MOM is insufficient, supplementing VLBW and ELBW infants with fortified donor human milk can shorten the time to achieve enteral nutrition and reduce the use rate and time of PICC, the incidence of late-onset sepsis, and the times of red blood cell transfusion.

ABSTRACT Objective: To develop a rapid method for analysing polyphenols, which are potentially active antioxidants against neonatal oxidative stress, from small human milk (HM) volumes. Methods: Acid and alkaline extractions were compared using two dyes: Folin-Ciocalteu and Fast Blue BB. Linearity, sensitivity, recovery percentage, polyphenol content, precision, and stability were assessed in 14 HM samples and compared using the Kruskal-Wallis H test (p<0.05). The best technique was applied to 284 HM samples to determine their polyphenolic content and its association with maternal diet by multifactorial linear regression. Results: Acidic extraction successfully recovered the gallic acid reference standard, whereas alkaline extraction overestimated it. Calibration curves for all methods were linear (R2>0.96) up to 500 mg/L. All bicarbonate-based Folin-Ciocalteu methods assayed were stable and repeatable, whereas Fast Blue BB-based variants were not. HM polyphenols (mean=94.68 mg/L) positively correlated to the dietary intake of hydroxycinnamic acids, the most consumed polyphenolic family in this population. Conclusions: A bicarbonate-based Folin-Ciocalteu micromethod allowed the accurate determination of polyphenols in HM, which might be useful for translational research settings and HM banks.
RESUMO Objetivo: Desenvolver um método rápido para analisar polifenóis, que são antioxidantes potencialmente ativos contra o estresse oxidativo neonatal, em pequenos volumes de leite humano (LH). Métodos: Foram comparadas extrações ácidas e alcalinas usando dois corantes: Folin-Ciocalteu e Fast Blue BB. Foram avaliadas variáveis como linearidade, sensibilidade, percentagem de recuperação, teor de polifenóis, precisão e estabilidade em 14 amostras de LH, comparadas usando o teste de Kruskal-Wallis H (p<0,05). A melhor técnica foi aplicada a 284 amostras de LH para determinar seu teor polifenólico e sua associação com a dieta materna por regressão linear multifatorial. Resultados: A extração ácida recuperou com sucesso o padrão de referência do ácido gálico, enquanto a extração alcalina o superestimou. As curvas de calibração para todos os métodos foram lineares (R2>0,96) até os 500 mg/L. Todos os métodos testados baseados em Folin-Ciocalteu com bicarbonato foram estáveis e repetíveis, enquanto as variantes baseadas em Fast Blue BB não. Os polifenóis do HM (média=94,68 mg/L) correlacionaram-se positivamente com a ingestão dietética de ácidos hidroxicinâmicos, a família de polifenóis mais consumida nesta população. Conclusões: Um micrométodo baseado em bicarbonato de Folin-Ciocalteu permitiu a determinação precisa de polifenóis no HM, o que pode ser útil para configurações de pesquisa translacional e bancos de HM.

Background: Apropiate introduction to complementary feeding (CF) decreases the risk of nutritional diseases in infants; however there is a paucity of information about the characteristics of CF in mexican children. Objective: To characterize the complementary feeding of Mexican infants and its relation to the nutritional status. Methodology: Transversal, analytical and retrospective study in dyads that required medical care. We performed a nutritional evaluation of the infants and characterized the type of lactation, type and texture of initial solid foods and the subsequent feeding. Results: Final sample consisted of 141 children in which, 59.6% reported that feeding was provided exclusively with formula and only 40% received breast milk. 14.1% of the infants showed low weight-for-height, 17.7% low weight-for-age, and 24.1% low height-for-age. We observed that 55.3% of the infants did not receive complementary feeding with appropriate texture; 58.9% did not receive the appropriate amount; and 44.7, 62.4% and 11.3% received inappropriate amounts of carbohydrates, proteins and fats respectively. Conclusion: A high proportion of infants do not receive appropriate complementary feeding.

Objective:To analyze the differential expression of breast milk-derived extracellular vesicles (BM-EV) from mothers of preterm and term infants .Methods:Breast milk samples were collected from preterm and term delivery (three cases in each) at the Women's Hospital of Nanjing Medical University in 2019. BM-EV was extracted using ultracentrifugation. After preliminary identification of the characteristics of BM-EV, liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for protein quantification. Significantly up-regulated differential proteins (fold change≥1.5 and P<0.05) in the preterm group were screened. GO and KEGG were performed to predict the differentially expressed proteins' functional annotation and determine associated signaling pathways. Mann-Whitney U test and Fisher's exact test were used for intergroup comparisons. Pearson's correlation test describes the correlation of protein quantification values between samples. The differences in protein abundance were compared between the two groups using a t-test, followed by multiple corrections. Additionally, significantly enriched GO terms and KEGG pathways of the differentially expressed proteins were screened based on the hypergeometric distribution. Results:(1) There were three primiparae in the preterm group and one in the term group. Marker proteins CD9, CD81, and HSP70 were enriched in the BM-EV of both groups. (2) Six samples were comparable between groups and showed high reproducibility within groups. The correlation of protein quantification values between samples was up to 0.99. Furthermore, the coefficient of variation was 11.21% for preterm samples and 19.72% for term, and the data values in the preterm group were relative. (3) A total of 945 proteins were identified, and 156 were differentially expressed between preterm and term BM-EV, with 83 significantly up-regulated in preterm BM-EV. In the up-regulated proteins, the top three high-abundance proteins were complemented C4a, fatty acid synthase, and sclerostin domain-containing protein-1. (4) The biological processes or cellular components with the highest enrichment in GO functional prediction were mainly involved in hemoglobin and glycogen biosynthesis, immunological synapse formation, and phagocytosis mediated by the Fc γ receptor signaling pathway. The most relevant KEGG pathways were ribosome-related, complement and coagulation cascades, neutrophil extracellular trap formation, and Fc γ receptor-mediated phagocytosis.Conclusion:The significantly up-regulated differential proteins in BM-EV may play a protective role by regulating immunity, gastrointestinal function, and energy metabolism in preterm infants.

Neonatal necrotizing enterocolitis (NEC) is one of the leading causes of neonatal death and no effective therapeutic drugs are currently available. Breastfeeding is a safe and effective preventive measure for NEC. Human breast milk-derived exosomes (HM-exos), which are membranous vesicles in breast milk, play an important role in maintaining the integrity of the intestinal barrier and promoting the repair of intestinal epithelial cells (IECs) damage through protecting IECs from oxidative stress, improving the proliferation and migration of IECs, maintaining the tight connection between IECs, inhibiting inflammatory response and regulating immune response.

Breast milk, the product of mammalian evolution, provides infants with not only vital nutrients, but also an array of nourishing contents, including bioactive substances, microorganisms, and cells. Being a crucial stage of reproductive health, breastfeeding serves as the primary means of nutrient absorption during early life. However, the scientific evaluation of its health effects remains inaccurate. The study of breast milk has emerged as a new interdisciplinary research hotspot, offering a new paradigm for explorations in life health, disease prevention, clinical treatment, social ethics, and economic advancement. This paper reviewed and discussed the research progress of breast milk science both domestically and internationally and the gap in between, and proposed a promising perspective for future research and development.

ABSTRACT Objective This study aimed to conduct a literature review on safety in breastfeeding in mothers with COVID-19. An integrative review of national and international literature was carried out. Methods The search took place in the SciELO, LILACS and MEDLINE® databases. Results A total of 25 scientific articles that specifically addressed the theme of breastfeeding and its risk and protective factors for infection by SARS-CoV-2 were selected. According to the studies analyzed, although the presence of viral RNA had already been detected by reverse transcriptase polymerase chain reaction in breast milk samples, there are still no proven cases of vertical transmission via human milk. Conclusion Breastfeeding appears to be safe if practiced according to precaution measures recommended by the World Health Organization. In addition, there is evidence of a potential for immunological protection by transfer of antibodies against SARS-CoV-2 in breast milk. Breastfeeding should continue to be promoted even in cases of mothers with clinical suspicion or confirmation of COVID-19, as well as the provision of expressed breast milk in cases where there is no possibility of direct breastfeeding.

Objective:To analyze the factors influencing breast milk volume in mothers of preterm infants during the period of maternal separation.Methods:This study retrospectively analyzed the data from lactation diaries of mothers of preterm infants ( n=371) in neonatal intensive care unit from the first Affiliated Hospital of Zhengzhou University from January 2017 to August 2021. According to whether the milk production reached 800 ml/d or not within two weeks after delivery, these women were divided into the reached group ( n=289) or unreached group ( n=82). Two independent sample t-test and Chi-square test were used for univariate analysis, and logistic regression was used to analyze the influencing factors. Results:Mothers who achieved the target milk volume accounted for 77.9% (289/371). There were no statistically significant differences in the ratio of milk production ≥50 ml between breasts or between two adjacent breastfeeding sessions (both P>0.05), while there were statistically significant differences in the maternal education background[high school education or below:16.3% (47/289) vs 41.5% (34/82); junior college or above:83.7% (242/289) vs 58.5% (48/82); χ2=23.77], type of breast pump [diaphragm breast pump:34.9% (101/289) vs 51.2% (42/82); piston pump: 65.1% (188/289) vs 48.8% (40/82); χ2=7.14], pre-pregnancy body mass index [<18.5 kg/m 2: 3.5% (10/289) vs 4.9% (4/82);≥18.5~<24.0 kg/m 2: 90.7% (262/289) vs 61.0% (50/82); ≥24.0 kg/m 2: 5.9% (17/289) vs 34.1% (28/82); χ2=40.89], and the initiation of lactation instruction [within 7 d after delivery: 77.2% (223/289) vs 45.1% (37/82);at 7-14 d after delivery: 22.8%(66/289) vs 54.9%(45/82); χ2=31.28] between the reached and unreached group (all P<0.05). Logistic regression analysis showed that high school education or below ( OR=4.279, 95% CI: 2.253-8.126, P<0.001), diaphragm breast pump ( OR=2.352, 95% CI: 1.309-4.226, P=0.004), pre-pregnancy body mass index ≥24.0 kg/m 2 ( OR=9.352, 95% CI: 4.389-19.928, P<0.001), and seeking lactation consultation at 7-14 d after delivery ( OR=3.654, 95% CI: 2.043-6.535, P<0.001) were risk factors for not achieving the target milk volume. Conclusions:Instruction on breastfeeding for less-educated mothers of preterm infants should be strengthened. Using piston breast pump, maintaining pre-pregnancy body mass index within the normal range, and receiving lactation instruction as early as possible will contribute to achieving the target milk volume.

Resumo Objetivo Avaliar a qualidade microbiológica do leite humano pasteurizado proveniente de um Banco de Leite Humano do Estado de São Paulo. Métodos Estudo descritivo conduzido com 29 amostras de leite humano ordenhado pasteurizado (LHOP) obtidas entre julho de 2015 a março de 2016 por meio da avaliação dos registros da acidez titulável bem como da quantificação da microbiota heterotrófica (mesófilos, psicrófilos, termófilos), coliformes totais e termotolerantes, fungos filamentosos e leveduriformes e Staphylococcus spp. Realizou-se a avaliação dos parâmetros físico-químicos por meio do potencial hidrogeniônico-pH, teor energético-K e acidez Dornic-ºD. Análises estatísticas descritivas e bivariadas foram conduzidas. Resultados Evidenciou-se nas amostras a presença de psicrófilos (17,24%), termófilos (27,59%), mesófilos (55,17%), fungos filamentosos e leveduriformes (41,38%) e ausência de Staphylococcus spp. Detectou-se a presença de 82,76% de coliformes no teste presuntivo. Já no teste confirmativo VB constatou-se a presença de 54,16% de coliformes totais e no teste EC 33,33% de coliformes termotolerantes. Os valores de pH e de K não apresentaram oscilações, enquanto que, na expressão da acidez entre 3º a 15°D detectou-se crescimento microbiano. O microrganismo mesófilo, apresentou correlação positiva com variável da acidez Dornic (r=0.44;p=0.01). Conclusão A partir da avaliação da qualidade microbiológica das amostras de LHOP descartado e consideradas impróprias para consumo no referido BLH, especificamente com relação aos indicadores microbiológicos das condições de higiene, sugere que a inviabilidade das amostras possam estar associadas às boas práticas de manipulação do alimento.

Abstract Objective To assess the microbiological quality of pasteurized human milk from a Human Milk Bank in the State of São Paulo. Methods This is a descriptive study conducted with 29 pasteurized expressed human milk (PEHM) samples obtained between July 2015 and March 2016 by assessing titratable acidity records as well as quantifying heterotrophic microbiota (mesophiles, psychrophiles, thermophiles), total and thermotolerant coliforms, filamentous and yeast-like fungi and Staphylococcus spp. The physical-chemical parameters were assessed via hydrogen-pH potential, K-energy content and Dornic-ºD acidity. Descriptive and bivariate statistical analyzes were conducted. Results The presence of psychrophiles (17.24%), thermophiles (27.59%), mesophiles (55.17%), filamentous and yeast-like fungi (41.38%) and absence of Staphylococcus spp were evidenced in the sample. The presence of 82.76% of coliforms was detected in the presumptive test. In the confirmatory VB test, the presence of 54.16% of total coliforms was found and, in the EC test, we verified 33.33% of thermotolerant coliforms. The pH and K values did not show oscillations, whereas, in the expression of acidity between 3º and 15°D, microbial growth was detected. The mesophilic microorganism showed a positive correlation with the Dornic acidity variable (r=0.44; p=0.01). Conclusion Based on the microbiological quality assessment of the HMB samples discarded and considered unfit for consumption in the HMB, specifically regarding the microbiological indicators of hygiene conditions, it suggests that the infeasibility of the samples may be associated with good food handling practices.

Abstract Breast milk is considered a complete food and the immediate effects of breastfeeding on the babies'neurological development are already recognized. This study aimed to describe the importance of continued breastfeeding and the influence of fatty acids on the infant's neurological maturation. For the study development, a systematic review was adopted, in which online search bases such as SciELO, PubMed and Google Scholar were used and whose publications comprised the period from 2008 to 2021. Out of the 969 articles found, 47 of them were selected that fulfilled the objective of the study. Breast milk is essential for the child's development and the benefits extend into adulthood, such as less chance of developing obesity, cardiovascular diseases, diabetes, hypersensitivity reactions, respiratory and gastrointestinal diseases. The mother-child bond is strengthened, enabling the child to develop emotionally, in addition to reducing the incidence of cancer in the mother. Breast milk has essential fatty acids (AGEs), such as linoleic and alpha-linolenic acid, which are essential for the development of neurological, visual and cellular activities. These compounds are present in breast milk in greater proportion than other types of milk and the more the mother ingests foods such as deep and cold water fish, seeds, flaxseed, chia, the greater the presence of AGEs and more benefits for the embryo-fetal period and for the infant. Thus, encouraging the breast milk consumption through suction improves stomatognathic functions, promoting harmonious orofacial growth, muscle balance, breathing coordination and proper tongue posture.

Resumo O leite materno é considerado um alimento completo e os efeitos imediatos da amamentação no desenvolvimento neurológico dos bebês já é reconhecido. Esse estudo teve como objetivo descrever a importância da amamentação continuada e a influência dos ácidos graxos na maturação neurológica do lactente. Para o desenvolvimento do estudo, adotou-se uma revisão sistemática, no qual foram utilizadas as bases de busca on line como SciELO, PubMed e Google Acadêmico e cujas publicações compreenderam o período entre de 2008 a 2021. Dos 969 artigos encontrados, foram selecionados 48 que atenderam ao objetivo do estudo. O leite materno é fundamental para o desenvolvimento da criança e os benefícios se estendem até a vida adulta, tais como menor chances de desenvolver obesidade, doenças cardiovasculares, diabetes, reações de hipersensibilidade, doenças respiratórias e gastrintestinais. O vínculo mãe-filho fica fortalecido, dando condições à criança de se desenvolver emocionalmente, além de diminuir a incidência de câncer na mãe. O leite materno possui ácidos graxos essenciais (AGE), como linoleico e linolênico, que são fundamentais para o desenvolvimento das atividades neurológicas, visuais e celulares. Esses compostos estão presentes no leite materno em maior proporção que outros tipos de leite e quanto mais a mãe ingerir alimentos como peixes de águas profundas e frias, sementes, linhaça, chia, maior será a presença dos AGE e mais benefícios para o período embriofetal e para o lactente. Desta forma incentivar o consumo de leite materno de forma prolongada, pela sucção melhora as funções estomatognáticas, promovendo crescimento orofacial harmonioso, equilíbrio da musculatura, coordenação da respiração e postura adequada de língua.
