Lactancia materna exclusiva y trabajo. Su importancia en la medicina del trabajo / Exclusive breastfeeding and work. Its importance in occupational health

En todos los ámbitos laborales, sin excepción, es imprescindible la vigencia ineludible del derecho irrestricto de toda madre a ejercer, practicar, su lactancia con su bebé. Y las razones médicas debieran formar parte de campañas incesantes para que este derecho de las mamás esté absolutamente naturalizado en todos los niveles y en cada rincón del país. La lactancia materna protege al bebé de enfermedades infecciosas y le da la nutrición ideal para una vida más sana. Es fundamental desde el primer día de vida extrauterina hasta los 6 meses con exclusividad y luego continúa con suplementos vitamínicos y nutrientes apropiados. En todo lugar de trabajo deben existir lactarios como una estrategia de Salud Pública y en Medicina del Trabajo. (AU)

In all areas of work, without exception, the unavoidable validity of the unrestricted right of every mother to exercise, practice, breastfeeding with her baby is essential. And the medical reasons should be part of incessant campaigns so that this right of mothers is absolutely naturalized at all levels and in every corner of the country. Breastfeeding protects the baby from infectious diseases and gives it the ideal nutrition for a healthier life. It is essential from the first day of extrauterine life until 6 months exclusively and then continues with appropriate vitamin and nutrient supplements. In every workplace there must be lactation rooms as a strategy of Public Health and Occupational Medicine. (AU)

Maternal obesity and its repercussions on melatonin and cortisol in breast milk and human colostrum

Introduction: scientific evidence has highlighted the role of chronobiological disruptions in promoting obesity through mechanisms involving important circadian rhythm hormones: melatonin and cortisol. These hormones are present in human colostrum and serve as crucial maternal and child protection mechanisms against obesity and childhood infections, owing to the intense interaction between mother and child during pregnancy and breastfeeding. Consequently, the melatonin and cortisol hormones present in human colostrum hold promise as potential candidates for yielding clinically applicable results and supporting future intervention strategies aimed at reducing obesity and neonatal infections. However, there is a scarcity of literature on this subject. Objective: the objective of this study is to to analyze the impact of maternal obesity on the levels and functions of melatonin and cortisol in colostrum and breast milk. Methods: a systematic review of the scientific literature was conducted following the recommendations outlined in the PRISMA protocol. Original articles published in English were searched in the PubMed, Medline, Lilacs, and Scopus databases. There were no restrictions on the publication year. Results: a total of 37 articles were identified from the searched databases. After removing duplicates and applying the inclusion and exclusion criteria, only five studies were relevant to the topic: two studies addressing melatonin and three studies analyzing cortisol. This review revealed that melatonin levels are elevated in the colostrum of obese women, and for this particular group, it has the potential to restore phagocyte activity and increase lymphocyte proliferation. Studies on cortisol have demonstrated that maternal obesity does not alter the levels of this hormone in breast milk. Conclusion: breastfeeding should be encouraged for all populations, and further original research should be conducted to elucidate the protective mechanisms of colostrum and breast milk.

Introdução: evidências científicas enfatizam que disrupções cronobiológicas podem promover a obesidade por mecanismos envolvendo ação de importantes hormônios marcadores do ritmo circadiano: a melatonina e cortisol. Estes hormônios estão presentes no colostro humano e representam importante mecanismo de proteção materno infantil frente à obesidade e infecções infantis, devido à intensa interação entre mãe e filho durante a gravidez e amamentação. Assim, os hormônios melatonina e cortisol presentes no colostro humano representam promissores candidatos para fornecer resultados com capacidade de aplicação clínica e de embasamento de futuras estratégias de intervenção com enfoque na redução da obesidade e de infecções neonatais. Entretanto, são escassos os estudos na literatura sobre o tema. Objetivo: analisar as repercussões da obesidade materna sobre os níveis e as ações da melatonina e do cortisol no colostro e leite materno. Método: foi realizada uma revisão sistematizada da literatura científica seguindo as recomendações do protocolo Prisma. Foram pesquisados artigos originais, publicados em inglês, nas bases de dados PubMed, Medline, Lilacs e Scopus. Não houve restrição quanto ao ano de publicação. Resultados: foram identificados 37 artigos nas bases de dados pesquisados, 15 artigos foram excluídos por estarem duplicados, após aplicação do critério de inclusão e exclusão apenas 5 estudos tiveram relação ao tema, sendo 2 estudos abordando sobre melatonina e 3 pesquisas que analisaram o cortisol. Esta revisão mostrou que a melatonina está elevada em colostro de obesas e para este grupo ela possui potencial de restaurar atividade de fagócitos e de elevar a proliferação de linfócitos. Os estudos sobre o cortisol ilustraram que os níveis deste hormônio no leite materno não foram alterados pela obesidade materna. Conclusão: o aleitamento materno deve ser encorajado para todos os públicos, assim como mais pesquisas originais devem ser desenvolvidas para descrever os mecanismos protetores do colostro e leite materno

Breast cancer is the most common malignant tumor of the female reproductive system with a high incidence rate and is one of the main causes of cancer-related deaths in women. Modern research believes that pregnancy, breastfeeding, and other reproductive behaviors can cause the changes in the levels of female estrogen and progesterone and related receptors, and affect the morphology and function of breast tissue, which are associated with the occurrence of breast cancer. This paper aims to summarize the impact of breastfeeding on the occurrence of breast cancer and analyze their correlation to increase the maternal breastfeeding rate, reduce the occurrence of breast cancer, and lower the risk of breast cancer in women.

Advances in breast milk-derived probiotics / 国际儿科学杂志

Breast milk is the best source of nutrition for infants, and the microbial communities contained in breast milk can regulate the colonization of bacteria in the intestines of newborns and enhance their immunity.As microbial culture, isolation and identification techniques continue to evolve, more and more breast-milk-derived probiotics are being discovered.Common probiotics in breast milk include Lactobacillus, Bifidobacteria, Philococcus, Streptococcus thermophilus, etc.A large number of studies have proved that breast milk-derived probiotics have a certain role in the treatment of infantile colic, functional constipation, diabetes, mastitis and other diseases, and the natural source of breast milk probiotics, adapted to the milk matrix and other characteristics make it stand out from a group of probiotics.The discovery of probiotics isolated from breast milk and the exploration of their probiotic functions can not only provide an experimental basis for the addition of breast milk-derived probiotics to infant formula, but also provide new prospects for the treatment of various diseases.

Aim : To compare the efficacy of different non-pharmacological methods for reducing pain in Neonates. Methodology : During the study period of one year from July, 2019 to July, 2020, a total of 70 infants were consecutively recruited and divided into two groups. One group received 2ml of EBM and other group 2ml of 25% D is administered which was given 1 minute before Venepuncture. The outcome variables are the duration of cry after Venepuncture & NIPS score for both group. Result : The duration of cry was found to be higher in the group receiving EBM. The neonates in 25%D groups had lower Neonatal Infant Pain Scale (NIPS) score than EBM group (chi-sqr-10.34 & p-0.0057). Conclusion : In our study we found 25% Dextrose to be a better non-pharmacological Analgesic as compared to EBM during painful procedure in newborn.

Handling, Storage and Use of Expressed Breastmilk among Working Mothers of Infants in Anantnag, Kashmir

Rising number of mothers are expressing their breastmilk to feed their infants when away from them, which presents new issues for infant feeding. Having sound knowledge regarding expression, storage and use of breast milk is fi rst step towards promoting practice of expressed breast milk, which in turn promotes exclusive breastfeeding. Primary concern in this is handling, storage, and warming of expressed breastmilk. So all breastfeeding mothers should be motivated to learn different techniques of expression, storage and use of expressed breastmilk. The settings chosen for present study were 18 villages of Dachnipora block of district Anantnag (J&K) with a sample size of 50 mothers of infants. This setting was selected as per feasibility & availability of study subjects. A questionnaire was used for data collection. The study revealed that 46 percent of subjects had inadequate knowledge level, 54 percent had moderate knowledge level' and none of subjects had adequate knowledge level regarding expression, storage and use of expressed breast milk. A signifi cant association of knowledge level of mothers of infants was found with demographic variables, parity and previous experience with expression and storage at p'le;0.05 level and no association was found with variables like age, educational status, nature of job and monthly family income. To conclude, mothers of infants had insignifi cant level of knowledge about expression, handling, storage and use of expressed breast milk. If they are provided and supported with adequate and appropriate information from the beginning of their motherhood, they will make exclusive breastfeeding a success.

Health of the Newborn and Breastfeeding during the COVID-19 Pandemic: A Literature Review / Saúde do recém-nascido e amamentação durante a pandemia de COVID-19: Uma revisão da literatura

Abstract Objective The present article presents a literature review concerning the microbiota of breast milk and the influence of epigenetics in the susceptibility to COVID-19. Methods A literature review. Results Breastfeeding transfers microbiota, nutrients, diverse white blood cells, prebiotics, hormones, and antibodies to the baby, which provide short- and longterm immunological protection against several infectious, gastrointestinal, and respiratory illnesses. The little evidence available shows that breast milk very rarely carries the SARS-CoV-2 virus, and even in those cases, it has been discarded as the source of contagion. Conclusion The reviewed studies show evidence of a beneficial effect of breastfeeding and highlights its importance on the current pandemic due to the immune reinforcement that it provides. Breastfed individuals showed better clinical response due to the influence on the microbiota and to the nutritional and immune contribution provided by breast milk, compared with those who were not breastfed.

Maternal vaccination as an additional approach to improve the protection of the nursling: Anti-infective properties of breast milk

Abstract Human milk constitutes a secretion with unique functions of both nourishing the nursling and providing protection against enteric and respiratory infections, mainly due to its content of secretory IgA antibodies but also due to the presence of a plethora of bioactive factors. Specific IgA antibodies are produced locally by plasma cells derived from B lymphocytes that migrate from other mucosae to the mammary gland during lactation, particularly from the gastrointestinal and respiratory tracts. Therefore, here, the authors will provide a comprehensive review of the content and functions of different nutritional and bioactive anti-infectious components from breast milk, such as oligosaccharides, lactoferrin, haptocorrin, α-lactalbumin, k-casein, lysozyme, lactoperoxidase, mucin, fatty acids, defensins, cytokines and chemokines, hormones and growth factors, complement proteins, leukocytes and nucleic acids, including microRNAs, among many others, and the induction of antibody responses in breast milk after maternal vaccination with several licensed vaccines, including the anti-SARS-CoV-2 vaccine preparations used worldwide. Currently, in the midst of the pandemic, maternal vaccination has re-emerged as a crucial source of passive immunity to the neonate through the placenta and breastfeeding, considering that maternal vaccination can induce specific antibodies if performed during pregnancy and after delivery. There have been some reports in the literature about milk IgA antibodies induced by bacterial antigens or inactivated virus vaccines, such as anti-diphtheria-tetanus-pertussis, anti-influenza viruses, anti-pneumococcal and meningococcal polysaccharide preparations. Regarding anti-SARS-CoV-2 vaccines, most studies demonstrate elevated levels of specific IgA and IgG antibodies in milk with virus-neutralizing ability after maternal vaccination, which represents an additional approach to improve the protection of the nursling during the entire breastfeeding period.

Objetivo: existem evidências inconclusivas sobre a potencial carogenicidade das fórmulas lácteas em comparação com o leite materno. O estudo teve como objetivo comparar a detecção e contagem de Streptococcus mutans(S. mutans) e lactobacilos da saliva entre lactentes alimentados com leite materno (B), com fórmulas de leite puro (France Lait-FL) e suplementada com probióticos (Nan 1 optipro-N), e avaliar crescimento in vitro dessas bactérias em amostras de leite materno e fórmulas lácteas. Material e Métodos: amostras salivares foram obtidas com swabs de algodão estéreis de 60 lactentes que foram agrupados de acordo com o tipo de leite. As amostras foram cultivadas para obter a frequência de detecção e contagens bacterianas. Para a investigação in vitro, sete amostras de leite materno doado e sete amostras recém-preparadas de ambas as fórmulas lácteas foram inoculadas por ambas as bactérias e então cultivadas para avaliar o crescimento bacteriano. Resultados:lactobacilos foram detectados em todos os lactentes, enquanto não foram encontradas diferenças significativas na detecção de S. mutans entre os grupos. As contagens de ambos os microrganismos na saliva foram menores em (B), enquanto uma diferença insignificante foi encontrada entre (B) e (N). Diferenças significativas foram evidentes nas contagens bacterianas in vitro sendo mais baixas em (B) seguido por (N) e (FL). Conclusão: o leite materno e as fórmulas lácteas com suplementos probióticos podem ter um papel protetor contra a cárie dentária em lactentes. (AU)

Objective: inconclusive evidence exists regarding potential cariogenicity of milk formulas compared to breast milk. The study aimed to compare Salivary Streptococcus mutans (S. mutans) and lactobacilli detection and counts among breastfed (B), plain formula (France Lait 1) (FL) and probiotic supplemented formula (Nan 1 optipro) (N) infants and to assess in-vitro growth of these bacteria in breast milk and milk formula samples. Material and Methods:salivary samples were obtained using sterile cotton swabs from 60 infants that were grouped according to nursing milk type. Samples were cultured to obtain the detection frequency and bacterial counts. For the in-vitro investigation, seven donated breast milk samples and seven freshly prepared samples of both milk formulas were inoculated by both bacteria and then cultured to assess bacterial growth. Results:lactobacilli were detected in all infants, while no significant differences were found in S. mutans detection among groups. Counts of both microorganisms in saliva were lowest in (B) while, insignificant difference was found between (B) and (N). Significant differences were evident in in-vitro bacterial counts being lowest in (B) followed by (N) and (FL). Conclusion: breast milk and probiotic supplement infants' milk formulas may have a protective role against dental caries in infants.(AU)

Harassment of health professionals by the infant food industry at scientific events / Assédio da indústria de alimentos infantis a profissionais de saúde em eventos científicos

ABSTRACT OBJECTIVE To analyze the receipt of sponsorships from breast-milk substitute companies by health professionals in scientific events. METHODS Multicenter study (Multi-NBCAL) performed from November 2018 to November 2019 in six cities in different Brazilian regions. In 26 public and private hospitals, pediatricians, nutritionists, speech therapists, and a hospital manager were interviewed using a structured questionnaire. Descriptive analyses were carried out regarding the health professionals' knowledge about the Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeiras (NBCAL - Brazilian Code of Marketing of Infant and Toddlers Food and Childcare-related Products), companies sponsoring scientific events, and material or financial sponsorships received, according to profession. RESULTS We interviewed 217 health professionals, mainly pediatricians (48.8%). Slightly more than half of the professionals (54.4%) knew NBCAL, most from Baby-friendly Hospitals. Most health professionals (85.7%) attended scientific events in the last two years, more than half of them (54.3%) sponsored by breast-milk substitute companies, especially Nestlé (85.1%) and Danone (65.3%). These professionals received sponsorships in the events, such as office supplies (49.5%), meals or invitations to parties (29.9%), promotional gifts (21.6%), payment of the conference registration fee (6.2%) or ticket to the conference (2.1%). CONCLUSION The infant food industries violate NBCAL by harassing health professionals in scientific conferences, offering diverse material and financial sponsorships.

Foram realizadas análises descritivas do conhecimento dos profissionais de saúde sobre a Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeiras (NBCAL), das empresas patrocinadoras de eventos científicos e dos patrocínios financeiros ou materiais recebidos, conforme a categoria profissional. RESULTADOS Foram entrevistados 217 profissionais de saúde, principalmente pediatras (48,8%). Pouco mais da metade dos profissionais (54,4%) afirmaram conhecer a NBCAL, principalmente em Hospitais Amigos da Criança. A maior parte (85,7%) dos profissionais de saúde havia participado de congressos científicos nos últimos dois anos, mais da metade, 54,3%, deles apoiados pela indústria de substitutos do leite materno, em especial pela Nestlé (85,1%) e Danone (65,3%). Patrocínios foram recebidos por esses profissionais nos eventos, como materiais de escritório (49,5%), refeições ou convites para festas (29,9%), brindes (21,6%), pagamento de inscrição (6,2%) ou de passagem para o congresso (2,1%). CONCLUSÃO As indústrias de alimentos infantis infringem a NBCAL ao assediar profissionais de saúde em congressos científicos, oferecendo patrocínios materiais e financeiros diversos.
