Indications for extensively hydrolyzed cow's milk protein in the neonatal period.

A large proportion of prescriptions for extensively hydrolyzed cow's milk protein (CMP) in newborns are not based on any scientific data justifying the indication. Many of these prescriptions are old habits or are based on incomplete data. The aim of this article is to analyze these practices and propose recommendations. The following points are covered: (a) indications for extensively hydrolyzed formula based on studies demonstrating their benefits in these situations-newborns with a proven allergy to CMP and occasional prescription of supplements to breastfeeding; (b) possible indications not based on a high level of evidence-re-initiation of feeding due to necrotizing enterocolitis, short bowel syndrome, re-initiation of feeding of newborns following intestinal surgery, and laparoschisis if neither the mother's own milk nor milk from a lactarium is available; (c) unjustified indications-newborns at risk of atopy, prematurity, severe neurological pathologies, newborns who are hemodynamically unstable and/or have congenital cardiopathy, neonatal hypoxic-ischemic encephalopathy treated with hypothermia, and newborns with esophageal atresia or diaphragmatic hernia. By following this classification, the prescriber will be guided to use the milk best suited to the pathology, bearing in mind that each situation must be adapted individually and the tolerance and effectiveness of the food reassessed from a nutritional and functional point of view.

Pollutants in Breast Milk: A Scoping Review of the Most Recent Data in 2024.

Perinatal exposure to pollutants, including persistent organic pollutants (POPs) and heavy metals, poses significant risks to both mothers and children, marking this period as highly vulnerable. Despite the well-acknowledged benefits of breastfeeding, there exists a gap in comprehensive understanding regarding the impact of environmental pollutants on breast milk, underscoring the critical need for this study. Our research addresses this gap by exploring the intersection of environmental health and lactation, situated within the broader 'One Health' concept, thus contributing a novel perspective to the existing body of knowledge. This scoping review aims to examine recent research on the persistent presence of organic pollutants (POPs) and heavy metals in breast milk, thereby elucidating the environmental setting's impact on milk quality. We seek to highlight the innovative angle of our study by emphasizing the 'One Health' concept, which has not been thoroughly explored in the context of lactation and environmental pollutants. We performed a scoping review, consulting two online databases to identify articles published from 1995 to 2023 that reported on pollutants in breast milk, using the PRISMA checklist. This methodological approach underlines the comprehensive and up-to-date nature of our literature review, ensuring the relevance and timeliness of our findings. From a total of 54 relevant articles, findings indicate that POPs are present in higher concentrations in breast milk the longer the lactation period. These findings highlight the persistent and bioaccumulative nature of such contaminants, offering new insights into their long-term implications for maternal and infant health. This exposure does not appear time-sensitive, suggesting pollutants accumulated in maternal fat compartments can be excreted into human milk years after exposure, a novel finding that underscores the importance of considering long-term environmental exposures in lactation research. The presence of POPs and heavy metals in both infant formula and maternal milk underscores a critical need for further comparative studies to understand the health implications better. Our discussion extends the current dialogue on the safety of breastfeeding in polluted environments, providing a new framework for assessing risks and benefits. While breastfeeding remains the WHO-recommended nutrition for optimal infant growth, the findings emphasize the importance of continued risk reduction policies to protect mothers and infants from environmental contaminants in breast milk. Our conclusion calls for an integrated approach, combining public health, environmental science, and clinical practice to develop effective strategies for reducing exposure to environmental pollutants. This multidisciplinary perspective is a significant contribution to the field, paving the way for future research and policy development.

Intestinal Candida albicans overgrowth in IgA deficiency.

BACKGROUND: Secretory IgA interacts with commensal bacteria, but its impact on human mycobiota ecology has not been widely explored. In particular, whether human IgA-deficiency is associated with gut fungal dysbiosis remains unknown. OBJECTIVES: Our goal was to study the impact of IgA on gut mycobiota ecology. METHODS: The Fungi-Flow method was used to characterize fecal, systemic, and maternal IgA, IgM, and IgG responses against 14 representative fungal strains (yeast/spores or hyphae forms) in healthy donors (HDs) (n = 34, 31, and 20, respectively) and to also compare gut mycobiota opsonization by secretory antibodies in HDs (n = 28) and patients with selective IgA deficiency (SIgAd) (n = 12). Stool mycobiota composition was determined by internal transcribed spacer gene sequencing in HDs (n = 23) and patients with SIgAd (n = 17). Circulating CD4+ T-cell cytokine secretion profiles were determined by intracellular staining. The impact of secretory IgA, purified from breast milk (n = 9), on Candidaalbicans growth and intestinal Caco-2 cell invasion was tested in vitro. RESULTS: Homeostatic IgA binds commensal fungi with a body fluid-selective pattern of recognition. In patients with SIgAd, fungal gut ecology is preserved by compensatory IgM binding to commensal fungi. Gut Calbicans overgrowth nevertheless occurs in this condition but only in clinically symptomatic patients with decreased TH17/TH22 T-cell responses. Indeed, secretory IgA can reduce in vitro budding and invasion of intestinal cells by Calbicans and therefore exert control on this pathobiont. CONCLUSION: IgA has a selective impact on Calbicans ecology to preserve fungal-host mutualism.

Breastfeeding Success and Newborn Health before and during the COVID-19 Pandemic:A Single-Centre Comparative Study.

INTRODUCTION: Due to the SARS-CoV-2 pandemic, adjustments in patient and visitor traffic were made in hospitals to limit viral exposure. The primary objective of our study was to compare the breastfeeding success of healthy newborns in a maternity ward during the 2020 lockdown period compared with the same period in the previous year. MATERIAL AND METHODS: Single-center comparative study based on prospectively collected data. All neonates born alive, from a single pregnancy, and with a gestational age greater than 36 weeks were considered for this study. RESULTS: 309 infants born in 2020 and 330 born in 2019 were included. Among women who desired to exclusively breastfeed, the rate of exclusive breastfeeding at discharge from the maternity ward was higher in 2020 than in 2019 (85 vs. 79%; p = 0.078). After logistic regression analysis adjusted for potential confounders (i.e., maternal BMI, parity, mode of delivery, gestational age, and size at birth), study period remained significantly and independently associated with exclusive breastfeeding at discharge (OR [95% CI] = 1.645 [1.005; 2.694]; p = 0.046). Newborns born in 2020 were less likely to have weight loss ≥10% than those born in 2019 (OR [95% CI] = 2.596 [1.148; 5.872]; p = 0.017) but had similar need for phototherapy (p = 0.41). CONCLUSION: The success of exclusive breastfeeding during the 2020 lockdown period was increased compared with the same period in 2019.

Intervention during the Perinatal Period: Synthesis of the Clinical Practice Guidelines from the French National College of Midwives.

These clinical practice guidelines from the French National College of Midwives (CNSF) are intended to define the messages and the preventive interventions to be provided to women and co-parents by the different professionals providing care to women or their children during the perinatal period. These guidelines are divided into 10 sections, corresponding to 4 themes: 1/ the adaptation of maternal behaviors (physical activity, psychoactive agents); 2/ dietary behaviors; 3/ household exposure to toxic substances (household uses, cosmetics); 4/ promotion of child health (breastfeeding, attachment and bonding, screen use, sudden unexplained infant death, and shaken baby syndrome). We suggest a ranking to prioritize the different preventive messages for each period, to take into account professionals' time constraints.

Initiating and Supporting Breastfeeding: Guidelines for Interventions during the Perinatal Period from the French National College of Midwives.

Exclusive breastfeeding is recommended for children for the first 4 to 6 months of life, with complementary foods added thereafter. It is the most ecological way of protecting the child's and mother's health. Training of health professionals is required to avoid transmitting inconsistent information in 3 areas: 1) implementing these 3 predictors: safe skin-to-skin, first breastfeed, and rooming-in 24/7; 2) teaching and monitoring: i) early signs of waking and feeding rhythms, ii) positioning and latching, and iii) signs of effective transfer; and 3) referring women to specialized support services if difficulties arise (eg, inadequate milk production, pain, cracked nipples, engorgement). Breastfeeding should continue during mastitis or an abscess. Ultrasound-guided needle aspiration is beneficial in treating an abscess. Précis: Information is provided to enable health professionals to better support breastfeeding and help women with the most common difficulties, thus promoting breastfeeding initiation and duration.

Neonatal Hemodynamic Characteristics of the Recipient Twin of Twin-To-Twin Transfusion Syndrome Not Treated with Fetoscopic Laser Surgery.

Background: This paper's intent is to describe the neonatal hemodynamic characteristics of recipient twins of monochorionic pregnancies complicated with twin-to-twin transfusion syndrome (TTTS), born without prenatal fetoscopic selective laser coagulation (FSLC). Methods: Retrospective analysis of hemodynamic characteristics was performed during the first five days of life of recipient twins from untreated TTTS. Results: Forty-two recipient twins were included and divided into three groups: no hemodynamic impairment (NoHI) (n = 15, 36%), isolated high blood pressure (HighBP) (n = 12, 28%), and cardiac failure group (CF) (n = 15, 36%). Patients of both CF and HighBP groups had high systolic blood pressure during the first 12 h of life and ventricular hypertrophy at early echocardiography. Cardiac failure occurred at a median age of 14 h (IQR = 6−24) and was followed by a drop in systolic and diastolic blood pressure. Acute kidney injury was more frequent (93% vs. 25%, p < 0.001) and severe (p <0.001) in the CF group than in the HighBP group. The mortality rate in the CF group was 40%. Factors associated with CF were twin anemia-polycythemia sequence (p = 0.012), very preterm birth (p = 0.040), and polycythemia (p = 0.002). Conclusion: One-third of recipient twins born without prenatal FSLC developed life-threatening cardiac failure during the first 24 h of life.

The First 1000 Days of Infant.

The third edition of the Nursing and Pediatrics Congress was held in Paris from 16-19 June 2021, with the aim of contributing the experiences and reflections of relevant health professionals (pediatricians, pediatric surgeons, obstetricians, nurses, midwives, dieticians, and lactation consultants) to the knowledge of the most critical period of human life: its first 1000 days [...].

Chlorine Solutions for a Safe Method of Decontamination of Breast Pump Milk Collection Kits Before and After the Coronavirus Disease 2019 Pandemic.

To promote breast feeding and breast pumping is essential for the most vulnerable infants even if the current coronavirus disease 2019 (COVID-19) pandemic sanitary crisis imposes more stringent hygienic measures. As recommended by the Centers for Disease Control and Prevention, World Health Organization, and Milk Bank Association, "after each pumping session, all pump part that come into contact with breast milk should be appropriately disinfected." The present study proposed different methods than can be used and focus on the safety analysis of chlorine solution (CS) in terms of residual hypochlorous acid (HCA) and total trihalomethanes (THM). We also performed an efficacy testing of the CS approach to decontaminate the devices used to collect the milk (breast pumps and bottles). The bacteriologic results of 1,982 breast pump milk samples collected in three different settings showed a major decrease of the microbial contamination using either sterile device or decontamination with CS compared to a simple soap washing. The main messages from our study are to propose a guideline for the safe use of CS and to define situations when breast pump decontamination might be necessary: vulnerable babies for which sterile device is recommended; special circumstances, for example the current COVID-19 pandemic; special situations, for example women living in precarious conditions; or women pumping their milk at work but that would have low or no access to boiled water. Overall, cold decontamination reduced losses of milk for bacteriological reasons in human milk banks and may also be interesting to prevent horizontal contamination by virus like COVID-19.

Is There an Association of Being Breastfed as an Infant and Fertility Status as an Adult?

Background: Breastfeeding has many short-term and long-term health benefits for infants. Short-term benefits include protection against childhood infections and mortality in low-income countries. The adult long-term effects usually emphasized are a reduction of excess weight and type 2 diabetes. However, there is a lack of available data on the impact of having been breastfed on adult fertility. Indeed, infertility probably has a multifactorial origin, including an environmental origin. The aim of this study was to investigate whether having been breastfed could be associated with unexplained infertility. Materials and Methods: This research is an ancillary study of the case-control study ALIFERT, for which both fertile and infertile couples were recruited. Breastfeeding statuses, collected from childhood health records, were compared among fertile and infertile individuals. Anthropometrics parameters were also used for analysis. Results: About 65.6% of infertile women and 63.3% of fertile women were breastfed, and 69% of infertile men and 67.4% of fertile men were breastfed. There was no statistically significant difference between fertile and infertile groups. Nevertheless, infertile women who were not breastfed had a significantly higher body mass index than those who were breastfed (25.8 kg/m2 vs. 23.2 kg/m2). Conclusion: In our study, we did not observe any association between having been breastfed and fertility in adulthood. However, we observed that, in infertile women, having not been breastfed may influence weight in adulthood. Trial registration: NCT01093378 ALIFERT. Registered: March 25, 2010.

Bacillus cereus Induces Severe Infections in Preterm Neonates: Implication at the Hospital and Human Milk Bank Level.

Human breast milk (HBM) is a source of essential nutrients for infants and is particularly recommended for preterm neonates when their own mother's milk is not available. It provides protection against infections and decreases necrotizing enterocolitis and cardiovascular diseases. Nevertheless, HBM spoilage can occur due to contamination by pathogens, and the risk of a shortage of HBM is very often present. B. cereus is the most frequent ubiquitous bacteria responsible for HBM being discarded. It can contaminate HBM at all stages, from its collect point to the storage and delivery. B. cereus can induce severe infection in newborns with very low birth weight, with sometimes fatal outcomes. Although the source of contamination is rarely identified, in some cases, HBM was suspected as a potential source. Even if the risk is low, as infection due to B. cereus in preterm infants should not be overlooked, human milk banks follow strict procedures to avoid contamination, to accurately identify remaining bacteria following pasteurization and to discard non-compliant milk samples. In this review, we present a literature overview of B. cereus infections reported in neonates and the suspected sources of contamination. We highlight the procedures followed by the human milk banks from the collection of the milk to its microbiological characterization in Europe. We also present improved detection and decontamination methods that might help to decrease the risk and to preserve the public's confidence in this vital biological product for infants whose mothers cannot breastfeed.

Nutrition of Pregnant and Lactating Women in the First 1000 Days of Infant.

Nutrition for pregnant and breastfeeding women is fundamental to the development of the child in its first 1000 days and beyond. To evaluate the adequacy of this nutrition, we have relied on historical dietary surveys and on personal French studies (4 studies from 1997 to 2014) involving dietary surveys over 3 days (3D-Diet). Furthermore, our team specialized in lipids has measured the fatty acids of breast milk, which reflect the dietary intake of lipids, from breast milk (1997-2014) and from the lipids of cord blood and maternal fat tissue, in 1997. According to our results, pregnancy needs require an additional 300 Kcal, but surveys show a bad equilibrium of macronutrients: an excess of proteins of fetus [17% of total energy intake (TEI) vs. 15%], excess of fats (45% vs. 35%), excess of saturated fatty acids (SFA), not enough polyunsaturated fatty acids (PUFA), particularly omega 3, and a deficit in carbohydrates (45% vs. 55%). There is also a deficiency in calcium, iron, magnesium, zinc, and vitamins D, B6, B5, and folates. Breast milk adequately provides all the macronutrients necessary for the growth of the child. Proteins and carbohydrates vary little according to the mother's diet; on the other hand, its composition in lipids, trace elements, and vitamins is highly variable with the mother's diet of breast milk. In our study in 2014, in 80 participants, the diet was low in calories (1996 Kcal vs. 2200 Kcal RDA), normoprotidic, normolipidic, but low in carbohydrate, especially polysaccharides. We note a very insufficient intake of fish and dairy products, and therefore calcium, but also magnesium, zinc, iron, and vitamins D, E, B6, and folate. Consequently, if the mother does not achieve a diet adequate to her needs during pregnancy and breastfeeding, it will be necessary to resort to medicinal supplements in minerals, trace elements, vitamins, and omega 3.

Role of Daily Milk Volume and Period of Lactation in Nutrient Content of Human Milk: Results from a Prospective Study.

Most studies assessing the macronutrient content of human milk are published retrospectively using analyzers that fail to determine sodium content and do not take into account the role of volume in milk composition. We aimed to describe macronutrient content and sodium content in human milk over time, observe any associations between them, and determine the factors associated with the evolution of milk composition. A prospective, longitudinal, monocentric study was undertaken. Contents of protein, fat, and lactose of 102 milk samples from 40 mothers were determined using a human milk analyzer and that of sodium with a flame spectrophotometer. Milk volumes along with clinical data were recorded. Protein content in the fourth quartile of volume was significantly lower than that in the first three, suggesting the existence of a volume threshold for protein content at approximately 445 mL. After multivariate analysis, it was found that maternal age, average volume, and lactation period remained significantly associated with protein content, maternal age remained significantly associated with fat content, and only average volume with sodium content. In consideration of previous findings along with our data, we suggest that extra care should be taken with fortification for feeding preterm infants when the mother's milk volume is greater than 400-450 mL.

Promoting and Protecting Human Milk and Breastfeeding in a COVID-19 World.

The global COVID-19 pandemic has put enormous stress on healthcare systems and hospital staffing. However, through all this, families will continue to become pregnant, give birth, and breastfeed. Unfortunately, care of the childbearing family has been de-prioritized during the pandemic. Additionally, many healthcare practices during the pandemic have not been positive for the childbearing family or breastfeeding. Despite recommendations from the World Health Organization to promote early, direct breastfeeding and skin to skin contact, these and other recommendations are not being followed in the clinical setting. For example, some mothers have been forced to go through labor and birth alone in some institutions whilst some hospitals have limited or no parental visitation to infants in the NICU. Furthermore, hospitals are discharging mothers and their newborns early, limiting the amount of time that families receive expert lactation care, education, and technical assistance. In addition, some hospitals have furloughed staff or transferred them to COVID-19 wards, further negatively impacting direct care for families and their newborns. We are concerned that these massive changes in the care of childbearing families will be permanently adopted. Instead, we must use the pandemic to underscore the importance of human milk and breastfeeding as lifesaving medical interventions. We challenge healthcare professionals to change the current prenatal and post-birth practice paradigms to protect lactation physiology and to ensure that all families in need receive equal access to evidence-based lactation education, care and technical assistance.

Bacillus cereus infection in neonates and the absence of evidence for the role of banked human milk: Case reports and literature review.

BACKGROUND: Banked human milk (BHM) has inherent infectious risks, even when pasteurized. Because of the ubiquity of Bacillus cereus in the environment and its ability to resist the Holder pasteurization process, there is a concern that BHM might lead to severe B. cereus infections. OBJECTIVE: We reviewed observed and published cases to determine the potential causal role of BHM as the source of these infections. METHODS: Two infants in the province of Québec (Canada) developed a B. cereus neonatal infection, and both had received BHM. We conducted bacteriological studies to compare clinical isolates and those found in these cases. RESULTS: After extended culture of BHM retention lots, B. cereus was found to have been involved in batches related to the first case. However, molecular typing showed that the strain was different from the clinical isolate, therefore excluding BHM as the source of contamination. In the second case, a Brevibacillus spp was isolated, a species distinct from the clinical isolate. CONCLUSION: Based on these cases and others reported in the literature, a causal link between B. cereus contaminated BHM and preterm neonatal infection has never been documented. Therefore, the risk that BHM can cause this infection remains theoretical. Given the widespread presence of B. cereus in the hospital environment and its capacity to resist standard cleaning procedures, it seems likely that airborne or direct or indirect contact are the main sources of most, if not all, cases of severe B. cereus neonatal infections, even in babies exposed to BHM.

Simultaneous liquid chromatography-tandem mass spectrometry analysis of brominated flame retardants (tetrabromobisphenol A and hexabromocyclododecane diastereoisomers) in French breast milk.

TBBPA and HBCDs are the two classes of flame retardants that are still allowed for use by the European Commission. In May 2013, HBCDs were listed as Persistent Organic Pollutants under the Stockholm Convention, and they were banned with an exemption on EPS/XPS for cavity wall insulation. This study describes the development and optimisation of a rapid LC-ESI-MS/MS method using isotopic dilution quantification including a simplified extraction step using a mixture of solvents and sulphuric acid hydrolysis followed by the one-shot analysis of TBBPA and each of the α-, ß- and γ-HBCD diastereoisomers. The limits of detection and quantification (LOD and LOQ) were 0.5 and 2.5 ng g-1 (lipid weight, lw) for TBBPA and HBCD diastereoisomers, respectively. The method was applied to analyse 106 samples of individual mature breast milk. TBBPA was quantified in 42% of these samples within a range of

Effects of Maternal Supplementation With Omega-3 Precursors on Human Milk Composition.

BACKGROUND: Long-chain polyunsaturated fatty acids (LC-PUFAs) are important for newborn neurosensory development. Supplementation of breastfeeding mothers' diets with omega-3 PUFAs, such as alpha-linolenic acid (ALA), may increase their concentration in human milk. Research aim: This study aimed to assess human milk composition after 15-day supplementation regimens containing either omega-3 PUFAs or olive oil, which does not provide ALA. METHODS: A multicenter factorial randomized trial was conducted with four groups of breastfeeding women, with each group containing 19 to 22 women. After a 15-day ALA washout period, three groups received supplementation with omega-3 precursors for 15 days: an enriched margarine (M), a rapeseed oil (R), and a margarine and rapeseed oil (MR). The fourth was unexposed to omega-3 precursors (olive oil control diet, O). After 15 days, blind determination of human milk fatty acid (FA) composition was assessed by gas chromatography, and the FA composition was compared among groups using variance analyses. RESULTS: Alpha-linolenic acid content, expressed as the mean (standard deviation) total human milk FA percentage, was significantly higher after diet supplementation with omega-3 PUFAs, with values of 2.2% (0.7%) (MR), 1.3% (0.5%) (R), 1.1% (0.4%) (M), and 0.8% (0.3%) (O at D30) ( p < .003 for each comparison). The lowest LA-ALA ratio (5.5) was found in the MR group ( p < .001). Docosahexaenoic acid and trans FA concentrations did not differ among groups. CONCLUSION: In lactating women, omega-3 supplementation via the combination of enriched margarine and rapeseed oil increased the ALA content of human milk and generated the most favorable LA-ALA ratio for LC-PUFA synthesis.

Breastfeeding disruption during hospitalisation for bronchiolitis in children: a telephone survey.

BACKGROUND: Hospitalisation for an acute bronchiolitis might lead to unwanted weaning off breast feeding for several reasons (respiratory distress, use of enteral or parenteral feeding, mothers tiredness, among others), yet it has never been really evaluated or quantified. METHODS: We conducted this telephone survey to evaluate breastfeeding disruption during hospitalisation for bronchiolitis and try to identify its determining factors for future interventions. This cross-sectional study extends over one epidemic season of bronchiolitis in a tertiary care hospital. All patients aged 6 months or younger hospitalised with acute bronchiolitis and receiving at least partial breast feeding were eligible for the study (n=144). Patients discharged home whose parents accepted to be contacted for a phone survey were included. Parents were contacted 3 months (range 0.5-6) after discharge. RESULTS: Eighty-four patients were included in the study. Median length of hospital stay was 3 days (1; 34), and 27 patients spent some time in paediatric intensive care unit. Forty-three mothers stated that hospitalisation modified their breast feeding (17 stopped, 12 switched to partial breast feeding and 14 reduced without stopping). Mothers stated that the causes of breastfeeding disturbance were lack of support and advices (n=27) followed by child's respiratory disease (n=14), logistic hospital difficulties (n=13) and personal organisation issues (n=4). CONCLUSION: Admission to hospital with bronchiolitis may adversely affect breast feeding. Correct advices and support could be a determining factor, and further studies should focus on preventive interventions.
