Early supplementation for cow's milk allergy prevention in breastfed infants in Poland (ESCAPE-PL): a protocol for randomised controlled trial.

Introduction: Current recommendations for early introduction of cow's milk proteins in infants who cannot be breastfed vary and are inconsistent due to a lack of clear evidence. We aim to assess whether early supplementation with various nutritional interventions, including cow's milk formula (CMF), amino acid formula (AAF), donor human milk (DHM) or high-pressure processed 'pascalised' DHM (DHM-P) is effective for the primary prevention of cow's milk allergy (CMA) in breastfed neonates.

Methods And Analysis: We will perform an open-label randomised, controlled, head-to-head trial with four parallel arms in three Polish study centres (Warsaw).

The Impact of Dietary Habits and Maternal Body Composition on Human Milk Microbiota-Polish Pilot Study.

Human milk (HM) is a complex biological fluid that plays a significant role in infant health, influenced by maternal dietary habits and body composition. This study aimed to explore how maternal diet and nutritional status affect the microbial composition of HM. In this pilot study, 15 mothers were recruited from a maternity ward and assessed for dietary habits through a semi-structured food frequency questionnaire and a 3-day dietary record.

Development of lactation and breast/chestfeeding adverse event terminology (LaBAET) through a Delphi consensus approach.

Background: Most women who give birth will initiate lactation and breast/chestfeeding, with up to 40% of infants globally receiving human milk exclusively for the first 6 months of life. One of the studies indicates that 40% of breastfeeding women had used at least one prescription medication in the first 3 months postpartum. The lack of information on the safety of medications during lactation may lead to cessation of lactation in favor of treatments, therefore contribute to suboptimal breastfeeding rates.

Lactoferrin and SIgA Concentrations in Human Milk of SARS-CoV-Infected Mothers-Polish Cohort Study.

Human milk (HM) provides critical immunological support to neonates, serving as a key component of passive immunity during early life. The main aim of this cohort study was to compare the concentrations of lactoferrin (Lf), secretory immunoglobulin A (SIgA), C-reactive protein (CRP), and their ratios to total protein levels in the colostrum of postpartum women infected with SARS-CoV-2 and healthy controls. Colostrum samples (3-5 mL) were collected from 40 mothers (20 infected, 20 healthy) during the first wave of the COVID-19 pandemic in Poland.

Re-adenylation by TENT5A enhances efficacy of SARS-CoV-2 mRNA vaccines.

Despite the widespread use of mRNA vaccines against COVID-19, little is known about the metabolism of therapeutic RNAs. Here we use nanopore sequencing to analyse individual therapeutic mRNA molecules, focusing on their poly(A) tails. We show that the Moderna mRNA-1273 vaccine has a poly(A) tail of around 100 nucleotides, followed by an mΨCmΨAG sequence.

Impact of mother's own milk expression practices and processing treatments on infant health and growth outcomes: a systematic review protocol.

Introduction: Breastfeeding is the biological norm for infant nutrition. In certain scenarios, feeding at the breast is not possible, because of either maternal or neonatal reasons. In those cases, infants can still receive expressed mother's own milk (MOM) and its beneficial properties.

Assessing the impact of different donor milk treatments on infant health and growth: a systematic review protocol.

Introduction: Donor human milk (DHM) is the first alternative if mother's own milk is unavailable or contraindicated. Much DHM research has focused on its nutritional, immunological and biochemical composition in response to various maternal variables, standard human milk banking procedures and storage protocols. The current systematic review protocol, however, aims to systematically gather and analyse existing data pertaining to the impact of these aforementioned factors on the clinical, health-related and developmental outcomes observed in infants fed with DHM.

Good practice in lactation counseling for Ukrainian refugee mothers to ensure the health and mental benefits of breastfeeding - an observational study.

Purpose: The study presents a cross-sectional analysis of the population of Ukrainian women who received maternity care in 11 Polish hospitals.

Methods: Multidirectional lactation counseling was implemented from March to November 2023 by the Human Milk Bank Foundation in cooperation with UNICEF Refugee Response Office in Poland. Medical data were collected using questionnaires prepared for the study.

Emergency response and preparedness among Polish human milk banks: a comparison of the COVID-19 pandemic and the 2022 Ukrainian refugee crisis.

Introduction: In recent years, Poland has faced two major emergencies: the COVID-19 pandemic, a global-scale public health emergency in 2020, and the outbreak of a full-scale war in Ukraine, which forced over 9 million Ukrainians-mostly women and children-to flee from their country through the Polish-Ukrainian border in 2022.

Methods: In 2020 and 2022, we conducted two online questionnaires with human milk bank personnel to assess the impact of these emergencies on the human milk banking sector and its preparedness to face them. All 16 human milk bank entities operating in Poland were contacted and invited to participate in the study.

New alternatives to holder pasteurization in processing donor milk in human milk banks.

Infectious and toxicological risks are the main potential hazards that operators of Human Milk Banks (HMBs) encounter and must eliminate. HMBs are trying to implement procedures that allow to manage and sanitize human milk without altering significantly its nutritional and biologically protective components, obtaining a product characterized by a valid balance between safety and biological quality. The history of human milk processing is linked to the origins of HMBs themselves.

"I could not find the strength to resist the pressure of the medical staff, to refuse to give commercial milk formula": a qualitative study on effects of the war on Ukrainian women's infant feeding.

Introduction: During emergencies, breastfeeding protects infants by providing essential nutrients, food security, comfort, and protection and is a priority lifesaving intervention. On February 24, 2022, the war in Ukraine escalated, creating a humanitarian catastrophe. The war has resulted in death, injuries, and mass internal displacement of over 5 million people.

Essential and non-essential element concentrations in human milk samples and the assessment of infants' exposure.

As the data concerning element concentrations in human milk (HM) samples and their intake by infants are lacking in Poland, the present study aimed to explore this issue. The material consisted of HM samples obtained from 30 exclusively breastfeeding mothers during 4-6 weeks postpartum. Additionally, to identify the factors that may potentially affect HM composition, information regarding maternal data (anthropometry, body composition, and diet) was also collected.

Breastmilk mineral composition among well-educated mothers from Central Poland - Associations with maternal dietary intake, dietary patterns and infant psychomotor development.

Background: Maternal dietary habits could affect breastmilk mineral composition, which may influence infant development. Mineral dietary intake or supplementation slightly affects its breastmilk concentration. However, the intake of selected food groups or dietary patterns that reflect diet complexity could have a greater impact.

Vegan/vegetarian diet and human milk donation: An EMBA survey across European milk banks.

The nutritional adequacy of human milk (HM) from vegan/vegetarian mothers has been a matter of debate, and a variety of recommendations regarding the eligibility of these mothers as human milk donors exists. According to the latest evidence, HM from vegans/vegetarians is similar in its composition to that from omnivores, however, some differences may be observed regarding vitamin B and omega-3 fatty acids concentrations. Maternal supplementation of these compounds has been proven effective in increasing their HM concentration.

The cytokine trio - visfatin, placental growth factor and fractalkine - and their role in myocardial infarction with non-obstructive coronary arteries (MINOCA).

Myocardial infarction with nonobstructive coronary arteries (MINOCA) remains a puzzling clinical entity. It is characterized by clinical evidence of myocardial infarction (MI) with normal or near-normal coronary arteries in angiography. Given the complex etiology including multiple possible scenarios with varied pathogenetic mechanisms, profound investigation of the plausible biomarkers of MINOCA may bring further pathophysiological insights and novel diagnostic opportunities.

Feeding Strategies in Newborns and Infants During the COVID-19 Pandemic-Polish Cross-Sectional Study.

We aimed to analyze factors affecting feeding strategies of newborns and infants during the COVID-19 pandemic in Poland. The cross-sectional study using a self-developed CAWI questionnaire was conducted between February and April 2021 among Polish mothers. The analysis included responses from 1,485 women who delivered during the COVID-19 pandemic restrictions.

Investigating donor human milk composition globally to develop effective strategies for the nutritional care of preterm infants: Study protocol.

Background: Globally, almost 15 million infants are born prematurely each year, disproportionately affecting low and middle-income countries. In the absence of mother's milk, the World Health Organization recommends using donor human milk (DHM) due to its protective effect against necrotizing enterocolitis, a life-threatening intestinal disorder. The use of DHM is increasing globally, with many low and middle-income countries integrating donor milk banks into their public health strategies to reduce neonatal mortality, yet very little is known about the nutritional composition of DHM.

Factors Influencing Cortisol Concentrations in Breastmilk and Its Associations with Breastmilk Composition and Infant Development in the First Six Months of Lactation.

Previous studies provided contradictory results regarding the influence of maternal, seasonal, and infant factors on breastmilk cortisol, and its associations with breastmilk composition and infant development. This study aimed to assess breastmilk cortisol levels at the first, third, and sixth months of lactation and evaluate the associations with maternal psychosocial, seasonal, and infant factors, breastmilk composition, and infant anthropometric and psychomotor development and temperament. Cortisol concentrations were assessed by ELISA in 24 h breastmilk samples obtained from 38 healthy mothers.

The review follows the PRISMA ScR Extension guidelines. The research was conducted in Scopus, Medline via Pubmed, and Web of Science databases from 1 March 2020 to 31 May 2021, using 392 combinations of keywords.

Microbiological Quality of Milk Donated to the Regional Human Milk Bank in Warsaw in the First Four Years of Activity.

As the survival rate for preterm infants increases, more emphasis is placed on improving health-related quality of life through optimal nutritional management. Human Milk Banks (HMBs) provide bioactive nutrients and probiotic microorganisms to premature newborns, especially in the first year of life. Donated milk screening and selection of potential donors ensures the quality and microbiological safety of the donated milk.

Human Milk Oligosaccharides Exhibit Biofilm Eradication Activity Against Matured Biofilms Formed by Different Pathogen Species.

Human milk oligosaccharides (HMOs) have been shown to exhibit plenty of benefits for infants, such as prebiotic activity shaping the gut microbiota and immunomodulatory and anti-inflammatory activity. For some pathogenic bacteria, antimicrobial activity has been proved, but most studies focus on group B streptococci. In the present study, we investigated the antimicrobial and antibiofilm activities of the total and fractionated HMOs from pooled human milk against four common human pathogenic Gram-negative species (, , , and ) and three Gram-positive species (, , and ).
