Introdução: A segurança e eficácia do uso de medicamentos durante a lactação são preocupações para mães e profissionais de saúde. Esta pesquisa analisa as orientações das bulas de medicamentos comumente prescritos para dispepsia e constipação, que visa fornecer informações essenciais para orientar as decisões terapêuticas durante esse período crucial da maternidade. Objetivos: Analisar as informações das bulas sobre contraindicações de medicamentos para dispepsia e constipação durante a amamentação, verificando se estão de acordo com as evidências científicas. Métodos: Medicamentos para dispepsia e constipação foram selecionados de acordo com a classificação da Anatomical Therapeutic Chemical (ATC) e o registro ativo no Brasil. A presença de contraindicações para o uso de medicamentos nas bulas do profissional de saúde e do paciente foi comparada com as informações contidas no manual técnico do Ministério da Saúde, Medicamentos e Leite Materno, LactMed, UptoDate, Micromedex, Documento Científico da Sociedade Brasileira de Pediatria e Reprotox. Resultados: Nenhuma informação sobre o uso durante a amamentação foi encontrada em 20,0 e 24,3% das bulas para dispepsia e constipação, respectivamente. A concordância entre as bulas dos medicamentos para dispepsia e as fontes consultadas foi baixa (27,2% das bulas contraindicavam o medicamento na lactação, enquanto nas fontes o percentual de contraindicação variou de 0 a 8,3%). Com relação a medicamentos para constipação, 26,3% das bulas os contraindicavam, enquanto nas fontes o percentual variou de 0 a 4,8%. Conclusões: O estudo mostrou que pelo menos duas em cada dez bulas para dispepsia e constipação não fornecem informações adequadas sobre o uso desses medicamentos em lactentes, e também que houve baixa concordância entre o texto das bulas e as fontes de referência quanto à compatibilidade do medicamento com a amamentação.

Introduction: The safety and effectiveness of medication use during lactation are concerns for mothers and healthcare professionals. This research analyzes the instructions on the leaflets of medications commonly prescribed for dyspepsia and constipation, which aims to provide essential information to guide therapeutic decisions during this crucial period of motherhood. Objectives: To analyze the information in package inserts about contraindications of drugs for dyspepsia and constipation during breastfeeding, verifying whether these are consistent with scientific evidence. Methods: Drugs for dyspepsia and constipation were selected according to the Anatomical Therapeutic Chemical (ATC) classification and active registry in Brazil. The presence of contraindications for the use of medications in the health professional's and patient's package inserts was compared with the information in the technical manual of the Ministry of Health, Medications and Mothers' Milk, LactMed, UptoDate, Micromedex, Documento Científico da Sociedade Brasileira de Pediatria and Reprotox. Results: No information about use during breastfeeding was found in 20.0 and 24.3% of leaflets for dyspepsia and constipation, respectively. The agreement between the leaflets of medications for dyspepsia and the sources consulted was low (27.2% of the leaflets contraindicated the medication during lactation, while in the sources the percentage of contraindication varied from 0 to 8.3%). In relation to medicines for constipation, 26.3% of the leaflets contraindicated them, while in the sources the percentage ranged from 0 to 4.8%. Conclusions: The study pointed out that at least two out of every ten package inserts for dyspepsia and constipation do not provide adequate information on the use of these drugs in infants, and also shows low concordance between the text of the package inserts and the reference sources regarding compatibility of the drug with breastfeeding.

Para tirar dúvidas sobre o processo de doação, o novo episódio do Ped Cast responde as principais perguntas sobre o tema, com a ajuda da dra. Simone Silva Ramos, membro do DC de Aleitamento Materno da SBP.

Pesquisa do Observa Infância mostra que pouco mais de 30% das mães se informa sobre amamentação na internet

Levantamento do Comitê Gestor da Internet no Brasil realizado no final de 2023 indica que 84% da população do país tem acesso à internet. Mesmo diante desse número, apenas 34,5% das mães de crianças menores de cinco anos acessam a rede para se informar sobre amamentação, informa o Estudo Nacional de Alimentação e Nutrição Infantil de 2019 (ENANI-19), cuja base de dados foi disponibilizada em junho.

ADECUACIÓN DE LA ALIMENTACIÓN COMPLEMENTARIA EN DIFERENTES ESCENARIOS DE COMPONENTE LÁCTEO DURANTE EL PRIMER AÑO DE VIDA / ADEQUACY OF COMPLEMENTARY FEEDING IN DIFFERENT DAIRY COMPONENT SCENARIOS DURING THE FIRST YEAR OF LIFE

Introducción: El primer año de vida del niño constituye una de las etapas más vulnerables del ciclo de vida. La leche humana es el alimento óptimo desde el nacimiento hasta los 2 años o lo que la familia desee. Aunque muy pocas circunstancias clínicas contraindican la lactancia, menos de la mitad de los niños la reciben en forma exclusiva hasta los 6 meses. En esas situaciones, se plantea la controversia acerca de la mejor opción de leche a utilizar, en combinación con los alimentos complementarios. Desarrollo: En circunstancias en que la lactancia materna (LM) se halla disminuida o discontinuada, la recomendación nutricionalmente más adecuada es el uso de fórmulas infantiles. Diferentes motivos determinan que la leche de vaca (LV) sea la última opción, por su propio perfil de nutrientes y su condición de factor de riesgo de deficiencia de hierro en menores de 2 años. Se desarrollaron cuatro escenarios según la edad del niño/a: 6 a 8 meses y 9 a 12 meses, que combinan LM, LV o fórmula, y ejemplifican tipo y cantidades de alimentos complementarios junto con los resultados en términos de adecuación de energía y nutrientes. Conclusiones: Un adecuado manejo del componente lácteo en el primer año de vida contempla eventuales inadecuaciones cuando la alimentación complementaria es precoz, tardía o inadecuada en densidad nutricional, y representa una ventana crítica para un buen crecimiento y el desarrollo, la conformación de una microbiota abundante y diversa y el desarrollo de un patrón gustativo saludable

Introduction: The first year is one of the most vulnerable period of the life cycle. Human milk is the optimal food from birth to 2 years or whatever the family wants. Although very few clinical circumstances contraindicate breastfeeding, less than half of children receive it exclusively up to 6 months. In these cases, controversy arises about the best option of milk, in combination with complementary foods. Development: In circumstances in which breastfeeding (BF) is reduced or discontinued, the most nutritionally appropriate recommendation is the use of infant formulas. Different reasons determine that cow's milk (CV) is the last option, due to its own nutrient profile and its condition as a risk factor for iron deficiency below 2 years. Four scenarios were developed according to the child's age: 6 to 8 months and 9 to 12 months, combining BF, LV or formula, exemplifying type and quantities of complementary foods and the results in terms of energy and nutrients adequacy. Conclusions: Adequate management of the dairy component in the first year of life, contemplating possible inadequacies when complementary feeding is early, late or inadequate in nutritional density represents a critical window for good growth and development, the development of an abundant and diverse microbiota and of a healthy taste pattern

Infant formula supplemented with milk fat globule membrane compared with standard infant formula for the cognitive development of healthy term-born formula-fed infants: protocol for a randomised controlled trial.

INTRODUCTION: Milk fat globule membrane (MFGM) is a complex lipid-protein structure in mammalian milk and human milk that is largely absent from breastmilk substitutes. The objective of this trial is to investigate whether providing infant formula enriched with MFGM versus standard infant formula improves cognitive development at 12 months of age in exclusively formula-fed full-term infants. METHODS AND ANALYSIS: This is a randomised, controlled, clinician-blinded, researcher-blinded and participant-blinded trial of two parallel formula-fed groups and a breastfed reference group that were recruited in the suburban Adelaide (Australia) community by a single study centre (a medical research institute). Healthy, exclusively formula-fed, singleton, term-born infants under 8 weeks of age were randomised to either an MFGM-supplemented formula (intervention) or standard infant formula (control) from enrolment until 12 months of age. The reference group was not provided with formula. The primary outcome is the Cognitive Scale of the Bayley Scales of Infant Development, Fourth Edition (Bayley-IV) at 12 months. Secondary outcomes are the Bayley-IV Cognitive Scale at 24 months, other Bayley-IV domains (language, motor, emotional and behavioural development) at 12 and 24 months of age, infant attention at 4 and 9 months of age, parent-rated language at 12 and 24 months of age, parent-rated development at 6 and 18 months of age as well as growth, tolerance and safety of the study formula. To ensure at least 80% power to detect a 5-point difference in the mean Bayley-IV cognitive score, >200 infants were recruited in each group. ETHICS AND DISSEMINATION: The Women's and Children Health Network Human Research Ethics Committee reviewed and approved the study (HREC/19/WCHN/140). Caregivers gave written informed consent prior to enrolling in the trial. Findings of this study will be disseminated through peer-reviewed publications and conference presentations.

Role of breastfeeding in disease prevention.

Human milk provides the infant with many bioactive factors, including immunomodulating components, antimicrobials and prebiotics, which modulate the infant microbiome and immune system maturation. As a result, breastfeeding can impact infant health from infancy, through adolescence, and into adulthood. From protecting the infant from infections, to reducing the risk of obesity, type 1 diabetes and childhood leukaemia, many positive health outcomes are observed in infants receiving breastmilk. For the mother, breastfeeding protects against postpartum bleeding and depression, increases weight loss, and long-term lowers the risk of type 2 diabetes, breast and ovarian cancer, and cardiovascular diseases. Beyond infants and mothers, the wider society is also impacted because of avoidable costs relating to morbidity and mortality derived from a lack of human milk exposure. In this review, Medline was used to search for relevant articles to discuss the health benefits of breastfeeding and its societal impact before exploring future recommendations to enhance our understanding of the mechanisms behind breastfeeding's positive effects and promote breastfeeding on a global scale.

Breastfeeding assistance for preterm and low birth weight infants: best practices implementation project.

OBJECTIVE: To describe the process of best practices implementation for breastfeeding assistance for preterm and low birth weight infants. METHOD: Participatory research that used the evidence implementation methodology of the JBI, held at a university hospital in southeastern Brazil, with the participation of a multidisciplinary team and managers. STAGES: Situational diagnosis, baseline audit and feedback, protocol development, training, implementation, and monitoring. RESULTS: Seven audit criteria were defined. In the baseline audit, three criteria were met, with eleven barriers to be resolved being listed. The strategies carried out were protocol development and multidisciplinary and intersectoral training. After the training, compliance was achieved with the seven criteria audited in the first follow-up audit and five in the second, emphasizing the increase in compliance after the implementation of the outlined strategies. CONCLUSION: The project achieved the objective of improving evidence-based practice, and allowed the implementation of the institution's first breastfeeding protocol. However, it shows the need to maintain training for adherence and enculturation of new practices.

Breastfeeding challenges among adolescent mothers: a phenomenological study at the Korle Bu Teaching Hospital in Ghana.

BACKGROUND: The natural and best approach to give newborns the nutrients they need for healthy growth and development is through breast feeding. Breastfeeding rates fall more sharply with time for mothers under the age of 20 years. AIM: This study sought to explore the challenges experienced by adolescent mothers who visit the department of obstetrics and gynaecology of Korle Bu Teaching Hospital in Ghana. METHOD: This study employed a qualitative phenomenology design and collected data from adolescent mothers. Data were gathered with the aid of a semistructured in-depth interview guide from 13 breastfeeding adolescent mothers. Data for the study were analysed using content analysis. The study was conducted at the obstetrics and gynaecology department of Korle Bu Teaching Hospital, Ghana. FINDINGS: Two major themes were generated from the study to be the challenges that confront adolescent breastfeeding mothers, and they are maternal factors of breastfeeding barriers and societal factors of breastfeeding barriers. Subcategories were generated for both themes during the process. CONCLUSION AND RECOMMENDATION: Training of pregnant adolescents during antenatal care visits on how to manage the inability to lactate, breastfeeding stress, painful and sore nipple, engorged breast, stigma from society will lessen their burden. Furthermore, training close family members and friends on how to be kind and support adolescent mothers during breast feeding is important. In-service training should be organised for health workers to enhance their knowledge and practice of approaching and guiding adolescent mothers on effective breast feeding and the provision of cubicles in public places where adolescent mothers can comfortably breastfeed.

Measurement of iron absorption and iron gains from birth to 6 months in breastfed and formula-fed infants using iron isotope dilution.

Little is known about iron kinetics in early infancy. We administered stable iron isotopes to pregnant women and used maternal-fetal iron transfer to enrich newborn body iron. Dilution of enriched body iron by dietary iron with natural isotopic composition was used to assess iron kinetics from birth to 6 months. In breastfed (BF, n = 8), formula-fed (FF, n = 7), or mixed feeding (MF, n = 8) infants, median (interquartile range) iron intake was 0.27, 11.19 (10.46-15.55), and 4.13 (2.33-6.95) mg/day; iron absorbed was 0.128 (0.095-0.180), 0.457 (0.374-0.617), and 0.391 (0.283-0.473) mg/day (BF versus FF, P < 0.01); and total iron gains were 0.027 (-0.002-0.055), 0.349 (0.260-0.498), and 0.276 (0.175-0.368) mg/day (BF versus FF, P < 0.001; BF versus MF, P < 0.05). Isotope dilution can quantify long-term iron absorption and describe the trajectory of iron depletion during early infancy.

Antidepressant Medication Use During Lactation: A Review for Providers.

This article presents a summary of information found within the existing medical literature on the pharmacological treatment options for maternal depression during lactation and the concurrent effects on the breastfeeding infant. Existing data on safety and efficacy varies by treatment modality. Medications used to treat depression are all secreted in breast milk to some extent; however, most antidepressants are considered relatively safe to use during breastfeeding. The selective serotonin reuptake inhibitors (SSRIs) sertraline and paroxetine are present in low levels and are considered preferred agents. Safety data for other antidepressants varies, however. monoamine oxidase inhibitors (MAOIs) should generally be avoided. Available references and resources can help providers optimize treatment of maternal depression while mitigating risk to the infant. Optimizing treatment of maternal depression is a complicated undertaking, which should be made in conjunction with the provider through shared decision making with the patient. Specific properties of any proposed medication, such as the relative infant dose and side effect profile, should always be taken into account during the decision-making process.

Diagnosis and management of a herpes nipple infection that resulted in neonatal HSV encephalitis.

We present a case of a primigravida in her 30s who had a caesarean delivery of dichorionic diamniotic twins at 33 weeks of gestation. Her postpartum course was complicated by a herpes simplex virus (HSV) infection of her nipple, found after her neonates were diagnosed with HSV encephalitis. She was evaluated at her 3-week postpartum visit and reported that her neonates were concurrently admitted to the neonatal intensive care unit with disseminated neonatal HSV-1. The patient and her partner were in a monogamous relationship with no known history of HSV. Physical examination demonstrated a vertical fissure on the face of her right nipple and a small cluster of vesicles on her left hand. PCR swabs of the lesions were positive for HSV-1 at both locations. The patient was started on oral valacyclovir 1000 mg two times per day, topical acyclovir ointment applied 4-6 times per day and mupirocin ointment applied 3 times per day to her breast with resolution of her breast lesions. She was able to continue expressing her breastmilk with the help of a pump and then resumed breastfeeding once her infection was cleared. Her infants recovered after prolonged parenteral antiviral therapy with age-appropriate development at follow-up.

Determinants of prenatal breastfeeding knowledge, attitudes and self-efficacy among Burmese migrant pregnant mothers in Samut Sakhon Province, Thailand: a cross-sectional study.

OBJECTIVE: The study aimed to explore the determinants of prenatal breastfeeding knowledge, attitudes and self-efficacy among Burmese migrant pregnant mothers in Samut Sakhon Province, Thailand. DESIGN: The data were collected as part of a baseline survey of a randomised controlled trial. SETTING AND PARTICIPANTS: A total of 198 Burmese migrant mothers between 28th and 34th weeks of gestation were recruited from the antenatal care clinic of Samut Sakhon Hospital. PRIMARY OUTCOME MEASURES: Breastfeeding knowledge, attitudes and self-efficacy RESULTS: The prevalence of good breastfeeding knowledge was 65.7% (n=130), positive attitudes towards breast feeding were 55.1% (n=109) and high breastfeeding self-efficacy was 70.7% (n=140). Multivariate logistic regression models revealed that mothers aged above 25 years (adjusted OR, AOR 3.1, 95% CI 1.2 to 7.9), being Bamar (AOR 2.3, 95% CI 1.2 to 4.4), having support from husband (AOR 2.3, 95% CI 1.2 to 4.6) and having previous childbirth experience (AOR 2.5, 95% CI 1.3 to 4.8) were the main determinants of good breastfeeding knowledge. Similarly, being Bamar (AOR 2.8, 95% CI 1.5 to 5.3), having high school education (AOR 4.3, 95% CI 1.8 to 10.1) and having access to workplace breastfeeding support (AOR 5.3, 95% CI 1.4 to 20.1) were found to be significant predictors of positive attitudes towards breast feeding. Moreover, mothers aged above 25 years (AOR 2.9, 95% CI 1.1 to 7.8), being Bamar (AOR 2.4, 95% CI 1.2 to 5.1), being unemployed (AOR 7.8, 95% CI 1.9 to 31.9), having support of husband (AOR 3.2, 95% CI 1.5 to 7.0), having previous breastfeeding experience for 6 months or more (AOR 5.0, 95% CI 2.1 to 11.7) and having intention to exclusively breastfeed (AOR 2.7, 95% CI 1.3 to 5.8) had significant associations with high breastfeeding self-efficacy. CONCLUSION: The prenatal breastfeeding knowledge, attitudes and self-efficacy among Burmese migrant mothers were influenced by many factors. A comprehensive understanding of these factors will enable policy-makers and healthcare providers to develop context-specific interventions for the promotion of exclusive breast feeding among Burmese migrant mothers in Thailand.

Impact of different obstetric interventions and types of delivery on breastfeeding: a nationwide cross-sectional survey of Hungarian women.

BACKGROUND: We assessed the effect of different obstetric interventions and types of delivery on breastfeeding. METHODS: A quantitative, cross-sectional study was carried out using an online questionnaire. Data collection was performed in 2021 in Hungary. We included biological mothers who had raised their at least 5-year-old child(ren) at home (N = 2,008). The questionnaire was completed anonymously and voluntarily. In addition to sociodemographic data (age, residence, marital status, education, occupation, income status, number of biological children, and anthropometric questions about the child and the mother), we asked about the interventions used during childbirth, and the different ways of infant feeding used. Statistical analysis was carried out using Microsoft Excel 365 and SPSS 25.0. Descriptive statistics, two-sample t tests, χ2 tests and ANOVA were used to analyse the relationship or differences between the variables (p < 0,05). RESULTS: We found that in deliveries where synthetic oxytocin was used for both induction and acceleration, there was a higher incidence of emergency cesarean section. However, the occurrence of vaginal deliveries was significantly higher in cases where oxytocin administration was solely for the purpose of accelerating labour (p < 0.001).Mothers who received synthetic oxytocin also received analgesics (p < 0.001). Women giving birth naturally who used oxytocin had a lower success of breastfeeding their newborn in the delivery room (p < 0.001). Children of mothers who received obstetric analgesia had a higher rate of complementary formula feeding (p < 0.001). Newborns born naturally had a higher rate of breastfeeding in the delivery room (p < 0.001) and less formula feeding in the hospital (p < 0.001). Infants who were breastfed in the delivery room were breastfed for longer periods (p < 0.001). Exclusive breastfeeding up to six months was longer for infants born naturally (p = 0.005), but there was no difference in the length of breastfeeding (p = 0.081). CONCLUSIONS: Obstetric interventions may increase the need for further interventions and have a negative impact on early or successful breastfeeding. TRIAL REGISTRATION: Not relevant.

Defining Optimal Cobalamin Status for Neonates and Infants.

BACKGROUND: An optimal cobalamin status is necessary for normal neurodevelopment. OBJECTIVE: To give a description of the epidemiology, pathophysiology and diagnostic challenges related to cobalamin insufficiency in neonates and infants in order to prevent its occurence. RESULTS: Inadequate cobalamin status is prevalent among neonates and young infants, due to a high prevalence of maternal cobalamin deficiency, exclusive breastfeeding for extended periods and late introduction of animal food. Cobalamin insufficiency is associated with delayed neurodevelopment and subtle clinical symptoms like feeding difficulties, regurgitations and constipation in young infants. Early diagnosis and treatment of impaired cobalamin status is important to prevent neurologic damage. CONCLUSION: Clinical suspicion of cobalamin insufficiency in infants should infer immediate biochemical testing and a plasma total homocysteine > 5.0 µmol/L indicate cobalamin insufficiency in need of intramuscular treatment with hydroxycobalamin, followed by introduction of animal food after 4 months of age.

Plain language titleVitamin B12 Is Important for Normal Development in Young ChildrenPlain language summaryVitamin B12, also called cobalamin, is found only in animal-sourced food. As low-meat, vegetarian, and vegan diets are increasingly popular in Western countries, vitamin B12 deficiency has become common, also in pregnant women and babies. Vitamin B12 status is essential for normal development and adequate levels of this vitamin is particularly important during pregnancy and the first years of life. In pregnancy, vitamin B12 is transferred from the mother to the fetus, so the baby has a store of this vitamin at birth. However, if the mother has vitamin B12 deficiency or the baby is born premature or with a low birth weight, the vitamin store may be insufficient and the baby may develop vitamin B12 deficiency. Maternal vitamin B12 status is important as long as the baby is exclusively breastfed. Breast milk contains vitamin B12, but the concentration decreases after 4 to 6 weeks and may be too low to support the baby until animal-sourced foods are introduced. The vitamin B12 content in formula milk is higher than in breast milk, and vitamin B12 deficiency is more common in exclusively breastfed babies. Vitamin B12 deficiency is associated with diffuse symptoms in small babies and may be difficult to detect, and the diagnosis have a mean delay of 4 months in this age-group. Typical symptoms are regurgitations or spitting up, constipation, problems with feeding and swallowing, and delayed psychomotor development. Suspicion of vitamin B12 insufficiency in babies should prompt immediate biochemical testing. Plasma total homocysteine is a metabolic marker of vitamin B12 status and can be measured in a blood sample from the baby. A level >5.0 µmol/L indicates probable vitamin B12 insufficiency and the baby should receive vitamin B12 supplementation, followed by introduction of animal-sourced foods at 3 to 4 months of age.

Influence of additive and maternal effects on production and reproduction traits in Murrah buffaloes: Insights from Bayesian analysis.

The aim of this research was to assess genetic parameters for first lactation production and reproduction traits in Murrah buffaloes by employing additive and maternal effects. Data on pedigree and specific traits of 640 Murrah buffaloes were gathered from 1997 to 2020. These traits encompassed first lactation milk yield (FLMY), 305-day first lactation milk yield (305FLMY), first lactation length (FLL), first lactation peak yield (FPY), first service period (FSP), first calving interval (FCI) and first dry period (FDP). Genetic evaluations employed six univariate animal models, accounting for both direct and maternal effects, facilitated by THRGIBBS1F90 and POSTGIBBSF90 programs. Fixed factors included in the analysis were period of calving, season of calving and age at first calving. The Bayesian estimates for direct heritability, derived from the most suitable model, were as follows: FLMY: 0.28 ± 0.01, 305FLMY: 0.30 ± 0.01, FLL: 0.19 ± 0.01, FPY: 0.18 ± 0.01, FSP: 0.12 ± 0.01, FCI: 0.14 ± 0.01 and FDP: 0.12 ± 0.01. Maternal effects were found significant, ranging from 5% to 10%, in first lactation traits under Model 2 and Model 5. Additionally, positive and significant genetic and phenotypic correlations were observed among the studied traits. In conclusion, selection based on 305-day first lactation milk yield suggests potential for genetic enhancement in Murrah buffaloes, advocating its inclusion in breeding programmes to bolster early performance. Also, consideration of maternal influences is necessary for genetic progress of animals.
