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.

Breastfeeding Needs in Adolescent Mothers: A systematic review.

Adolescent mothers face numerous challenges while breastfeeding. This study aimed to assess the breastfeeding needs of adolescent mothers. For this systematic review, Web of Science, PubMed, Scopus, Cochrane Library, SID and Magiran databases were searched. The initial search yielded 2,290 studies, of which 41 were included in this review. Adolescent mothers' breastfeeding requirements were grouped into 8 categories: (1) social support from healthcare providers, partners and families; (2) school support for breastfeeding mothers; (3) breastfeeding counselling based on cultural sensitivities; (4) educational assistance from health providers for adolescent mothers' families; (5) changing harmful cultural values and judgments about adolescent mothers' breastfeeding; (6) additional home or outpatient visits in the days following hospital discharge; (7) peer support and counselling; and (8) economic needs. To promote breastfeeding, policymakers and healthcare providers should devise specifically tailored programmes and interventions to cater to the specific requirements of adolescent mothers.

Exploring the associations of food and financial insecurity and food assistance with breastfeeding practices among first-time mothers.

OBJECTIVE: Social determinants of health (SDoH), such as food and financial insecurity and food assistance, are potentially modifiable factors that may influence breastfeeding initiation and duration. Knowledge gaps exist regarding the relationship between these SDoH and infant feeding practices. We explored the relationships of food and financial insecurity and food assistance with the continuation of breastfeeding at four months postpartum among mothers and whether race and ethnicity modified these associations. DESIGN: Mothers retrospectively reported food and financial insecurity and receipt of food assistance (e.g. Women, Infants and Children and Supplemental Nutrition Assistance Program) during pregnancy with their first child and infant feeding practices (exclusive/mostly breastfeeding v. exclusive/mostly formula feeding) following the birth of their first child. Sociodemographic-adjusted modified Poisson regressions estimated prevalence ratios and 95 % CI. SETTING: Minneapolis-St. Paul, Minnesota. PARTICIPANTS: Mothers who participated in the Life-course Experiences And Pregnancy study (LEAP) (n 486). RESULTS: Ten percent of mothers reported food insecurity, 43 % financial insecurity and 22 % food assistance during their pregnancies. At four months postpartum, 63 % exclusively/mostly breastfed and 37 % exclusively/mostly formula-fed. We found a lower adjusted prevalence of breastfeeding at four months postpartum for mothers who reported experiencing food insecurity (0·65; 0·43-0·98) and receiving food assistance (0·66; 0·94-0·88) relative to those who did not. For financial insecurity (aPR 0·92; 0·78, 1·08), adjusted estimates showed little evidence of an association. CONCLUSIONS: We found a lower level of breastfeeding among mothers experiencing food insecurity and using food assistance. Resources to support longer breastfeeding duration for mothers are needed. Moreover, facilitators, barriers and mechanisms of breastfeeding initiation and duration must be identified.

Breastfeeding experiences of women with perinatal mental health problems: a systematic review and thematic synthesis.

BACKGROUND: Despite its known benefits, breastfeeding rates among mothers with perinatal mental health conditions are staggeringly low. Systematic evidence on experiences of breastfeeding among women with perinatal mental health conditions is limited. This systematic review was designed to synthesise existing literature on breastfeeding experiences of women with a wide range of perinatal mental health conditions. METHODS: A systematic search of five databases was carried out considering published qualitative research between 2003 and November 2021. Two reviewers conducted study selection, data extraction and critical appraisal of included studies independently and data were synthesised thematically. RESULTS: Seventeen articles were included in this review. These included a variety of perinatal mental health conditions (e.g., postnatal depression, post-traumatic stress disorders, previous severe mental illnesses, eating disorders and obsessive-compulsive disorders). The emerging themes and subthemes included: (1) Vulnerabilities: Expectations versus reality; Self-perception as a mother; Isolation. (2) Positive outcomes: Bonding and closeness; Sense of achievement. (3) Challenges: Striving for control; Inconsistent advice and lack of support; Concerns over medication safety; and Perceived impact on milk quality and supply. CONCLUSIONS: Positive breastfeeding experiences of mothers with perinatal mental health conditions can mediate positive outcomes such as enhanced mother/infant bonding, increased self-esteem, and a perceived potential for healing. Alternatively, a lack of consistent support and advice from healthcare professionals, particularly around health concerns and medication safety, can lead to feelings of confusion, negatively impact breastfeeding choices, and potentially aggravate perinatal mental health symptoms. Appropriate support, adequate breastfeeding education, and clear advice, particularly around medication safety, are required to improve breastfeeding experiences for women with varied perinatal mental health conditions.

Treatment of spondyloarthritis with disease-modifying anti-rheumatic drugs during pregnancy and breastfeeding: comparing the recommendations and guidelines of the principal societies of rheumatology.

OBJECTIVE: This paper aims to provide an overview of the use of treatments available for axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) during pregnancy and breastfeeding, according to current national recommendations and international guidelines, as well as data on the impact on pregnancy outcomes of paternal exposure to treatment. METHODS: We performed a narrative review of national and international recommendations and guidelines on the reproductive health of patients suffering from rheumatic diseases. The last updated recommendations and guidelines were considered source data. RESULTS: We reported updated information regarding the treatment of axSpA and PsA with nonsteroidal anti-inflammatory drugs, intra-articular glucocorticoids, conventional synthetic disease-modifying antirheumatic drugs (DMARDs), biologic DMARDs, and targeted synthetic DMARDs during the preconception period, pregnancy, and breastfeeding, as well as data related to paternal exposure. We highlighted any medications that should be discontinued and/or not used in the reproductive age group and also treatments that may be continued, avoiding the withdrawal of drugs that can be used in the different phases, thus preventing the risk of increasing disease activity and flares before, during, and after pregnancy in SpA patients. CONCLUSIONS: The best management of pregnancy in patients with SpA is based on knowledge of updated drug recommendations, a careful and wise evaluation of the risks/benefits of starting or continuing treatment from the SpA diagnosis in a woman of childbearing age through pregnancy and lactation, and sharing therapeutic choices with other healthcare providers (in particular, gynecologists/obstetricians) and the patient.

Clinical study of ultrasound-guided minimally invasive catheterization combined with compound cortex phellodendri fluid in the treatment of lactational breast abscess.

OBJECTIVE: To retrospectively analyze the clinical practicability and value of ultrasound-guided minimally invasive catheterization combined with compound Phellodendron Phellodendri liquid in the treatment of breast abscess during lactation. METHODS: 139 patients with lactational breast abscess discharged from our hospital from January 2021 to November 2023 were selected. We divided them into groups according to treatment methods, analyzed whether there were statistical differences in observation indexes among groups and the risk factors affecting breastfeeding rate and treatment satisfaction. RESULTS: We found that numerical rating scale(NRS) score and incidence of breast fistula in group A were significantly lower than other, the continuous decrease of postoperative drainage in group A was higher than other, there were significant differences among groups (p<0.001). Univariate analysis showed that recovery time, drainage tube placement time, postoperative redness and swelling regression time, scar length, and VAS score of six groups were statistically significant (p<0.001). We found that the overall satisfaction and the rate of continued breastfeeding in group A (96.2%) were higher than other, the differences were statistically significant(p<0.05). Logistic regression analysis revealed that the significant risk factors influencing treatment satisfaction included the time of drainage tube placement, postoperative redness and swelling regression time, treatment group, surgical method, NRS score on the first day after operation, postoperative drainage volume, healing time, scar length, flushing drugs, and VAS score. Postoperative redness and swelling regression time, treatment group, operation method and VAS score are all risk factors that influence the outcome of breastfeeding. CONCLUSION: Ultrasound-guided minimally invasive catheterization combined with compound cortex phellodendri fluid in the treatment of breast abscess during lactation can not only reduce the pain caused by dressing change, but also offer numerous advantages, including shorter healing time, beautiful appearance, lower incidence of breast fistula, high satisfaction and high rate of continued breastfeeding.

Effects of prenatal fish oil supplementation on the development and performance of female kids after weaning.

This study was performed to determine the influence of fish oil, an omega-3 fatty acids source, supplemented to diets of goats throughout all stages of gestation on the growth and milk production of weaned female kids. Eighty German Fawn (75%) x Hair (25%) crossbred goats were randomly assigned to treatment (fish oil, FiO group) and control (Rumen protected fat, RPF group) groups during the first half of pregnancy. Subsequently, the FiO group was further allocated into FiO-FiO and FiO-RPF subgroups and RPF group was further divided into RPF-FiO and RPF-RPF subgroups containing 20 goats in each during the second half of pregnancy. The growth and feed intake of 41 female kids (aged 75.1 ± 6.73 days, with a mean live weight of 11.6 ± 3.00 kg) were recorded for a 98 day post-weaning, In the continuation of the study, live weight changes, milk yield and composition of young female goats from mating to the second month of lactation and the growth of female kids until weaning were studied for a total of 210 days. Maternal nutrition slightly influenced the live weight gain of female kids over a 98-day investigation period (p = 0.070). When growth performance was considered, a higher feed conversion efficiency of female offspring was determined in RPF-FiO (5.52) treatment group compare to female kids in other treatment groups (p = 0.086). However, the maternal feeding system significantly affected live weight in the RPF-FiO treatment group during the mating period (P = 0.054). Concerning the feed intake, maternal nutrition significantly affected the feed intake of female kids (p < 0.01) with the highest feed consumption in the FiO-RPF group. The findings of this study have shown that fish oil enriched diet given to goats during gestation improved daily live weight changes and total live weight gain of female kids despite the initial disadvantage after weaning. At mating time, the live weight of young female goats in the RPF-FiO treatment group, which exhibited the highest feed conversion ratio during the 98-day study, was higher than the remaining treatment groups. Maternal nutrition had no effect on milk yield or milk components in young goats during lactation. Young female goats born to dams in the FiO-RPF group showed better performance than the other groups regarding live weight performance of their offspring on 56th day postpartum.

Factors affecting infant feeding choices with a focus on barriers to exclusive breastfeeding in Western Jamaica: a qualitative study.

BACKGROUND: Despite the many benefits of exclusive breastfeeding to infants and mothers, only 33% of Jamaican infants are exclusively breastfed up to the recommend six months. This study was conducted to identify factors affecting mothers' feeding choices focusing on barriers to exclusive breastfeeding of infants six weeks to less than six months old. METHODS: A qualitative study consisting of four focus group discussion sessions was conducted among 22 mothers attending postnatal clinics in western Jamaica from May to August 2016. The transcripts were coded by three independent coders and content analysis conducted to generate themes. RESULTS: Four themes were identified namely, perceived advantages of breastfeeding centered mainly on the benefits of breastfeeding for the infant and mother, perceived barriers of breastfeeding highlighting physical pain and fatigue, supplementing culturally acceptable complementary foods and herbal remedies, and cultural norms including perception of how breastfeeding affects a woman's body, societal sources of breastfeeding information, satiation of infants, and family and other support. Mothers overwhelmingly agreed that breastfeeding was inexpensive, allowed them to bond with their infants and was good for the overall health and intellectual development of the infants. They identified painful nipples, engorged breasts, lack of sleep, physical exhaustion and pressure to return to work as barriers to breastfeeding. Mothers named a number of complementary foods, such as pumpkin, carrots, potato, banana, and chocho (Chayote), that were culturally accepted for feeding infants in Jamaica and discussed herbs that were considered to aid in infants' nutrition and overall health. Other cultural factors that were noted to influence exclusive breastfeeding were mothers feeling that breastfeeding would help their bodies, especially their bellies, go back to their pre-maternity figure, sources of breastfeeding information in the society including the internet, belief that breast milk alone does not satisfy babies, and family and other support. CONCLUSION: Mothers in this study identified unique challenges to exclusive breastfeeding that if addressed, would help to increase exclusive breastfeeding so that the World Health Organization's exclusive breastfeeding recommendations can be achieved.

Delivery mode and maternal gestational diabetes are important factors in shaping the neonatal initial gut microbiota.

Background: The infant gut microbiome's establishment is pivotal for health and immune development. Understanding it unveils insights into growth, development, and maternal microbial interactions. Research often emphasizes gut bacteria, neglecting the phageome. Methods: To investigate the influence of geographic or maternal factors (mode of delivery, mode of breastfeeding, gestational diabetes mellitus) on the gut microbiota and phages of newborns, we collected fecal samples from 34 pairs of mothers and their infants within 24 hours of delivery from three regions (9 pairs from Enshi, 7 pairs from Hohhot, and 18 pairs from Hulunbuir) using sterile containers. Gut microbiota analysis by Shotgun sequencing was subsequently performed. Results: Our results showed that geographic location affects maternal gut microbiology (P < 0.05), while the effect on infant gut microbiology was not significant (P = 0.184). Among the maternal factors, mode of delivery had a significant (P < 0.05) effect on the newborn. Specific bacteria (e.g., Bacteroides, Escherichia spp., Phocaeicola vulgatus, Escherichia coli, Staphylococcus hominis, Veillonella spp.), predicted active metabolites, and bacteriophage vOTUs varied with delivery mode. Phocaeicola vulgatus significantly correlated with some metabolites and bacteriophages in the early infant gut (P < 0.05). In the GD group, a strong negative correlation of phage diversity between mother and infants was observed (R = -0.58, P=0.04). Conclusion: In conclusion, neonatal early gut microbiome (including bacteria and bacteriophages) colonization is profoundly affected by the mode of delivery, and maternal gestational diabetes mellitus. The key bacteria may interact with bacteriophages to influence the levels of specific metabolites. Our study provides new evidence for the study of the infant microbiome, fills a gap in the analysis of the infant gut microbiota regarding the virome, and emphasizes the importance of maternal health for the infant initial gut virome.

Effectiveness of moisturising therapy in treating nipple trauma: a systematic review protocol.

INTRODUCTION: Breastfeeding is crucial in infant nutrition and bonding, recommended for at least 6 months and up to 2 years postpartum, providing health benefits for both infants and mothers. However, nipple trauma is common among lactating mothers. Moisturising therapies, such as hydrogel application, aim to promote the healing of nipple wounds. Despite various interventions proposed, comprehensive reviews evaluating the efficacy of moisturising therapies for nipple trauma are lacking. This review aims to appraise the effectiveness of moisturising therapy, particularly tailored for nipple trauma in lactating women. METHODS AND ANALYSIS: This systematic review protocol adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines and is registered in the International Prospective Register of Systematic Reviews. The focus will be on both randomised and non-randomised controlled trials addressing the treatment of nipple trauma in lactating women. In this context, 'moisturising therapy' is categorised as a non-pharmacological intervention applied directly to the nipple, excluding treatments for bacterial or fungal infections. The primary outcomes will include measures of the healing efficiency of nipple trauma and reduction in nipple pain. Searches will be conducted without date restrictions across multiple databases, including PubMed, CINAHL, the Cochrane Library, Web of Science, CiNii Research and Ichushi-Web, in addition to exploration of grey literature. Two independent reviewers will manage all stages of the review process, under the supervision of a third reviewer. Data extraction will encompass participant demographics, study methodologies, sample specifics and measured outcomes. Quality assessment will be conducted using the Joanna Briggs Institute Appraisal Checklist Tools. ETHICS AND DISSEMINATION: Ethics approval is not required for this study. The findings of this review will be disseminated through academic publications, detailed reports and presentations at relevant conferences. PROSPERO REGISTRATION NUMBER: CRD42023481761.

Newborn community health advancements among Ethiopian Orthodox Christian women in North Gondar, Ethiopia: community-based randomised trial protocol.

INTRODUCTION: Despite significant progress over past decades, neonatal and infant morbidity and mortality remain unacceptably high in Ethiopia. Simple interventions have been shown to improve the health of children and reduce mortality. These include promotion of exclusive breast feeding for the first 6 months of life, immunisation and utilisation of available newborn healthcare services, which are proven to improve newborn survival. This study aims to determine the impact of a behaviour change intervention that partners Orthodox priests with volunteer community health workers, known in Ethiopia as the Health Development Army and trains them to conduct newborn health outreach to improve care seeking, uptake of key interventions and identification of sick infants. METHODS: The study designed is a community-randomised trial conducted in the Central Gondar area. The behaviour change intervention pairs trained Orthodox priests with members of the Health Development Army to conduct community health outreach by identifying near-term pregnant women in their communities and educating them on the topics of exclusive breast feeding, immunisation, nutrition and uptake of available child healthcare services. The evaluation of the intervention will enrol up to 150 newborn-mother pairs from communities receiving the behaviour change intervention and another 150 pairs enrolled from control communities. The quantitative analysis will be done by comparing data between the intervention and control groups related to breast feeding, anthropometry, immunisation status and uptake of child health services. The primary outcomes are exclusive breastfeeding through 6 months, mid-upper arm circumference, completion of vaccinations and infant hospitalisation. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the University of Washington (STUDY00006942) and the University of Gondar (No.V/P/RCS/05/2523/2019) Institutional Review Boards. Oral consent was obtained for the formative study, whereas written consent (or witnessed thumbprint) will be obtained from all enrolled mothers. Results will be communicated to community members, relevant government agencies and other stakeholders. TRIAL REGISTRATION NUMBER: NCT05111899.

Faecal microbiota and cytokine profiles of rural Cambodian infants linked to diet and diarrhoeal episodes.

The gut microbiota of infants in low- to middle-income countries is underrepresented in microbiome research. This study explored the faecal microbiota composition and faecal cytokine profiles in a cohort of infants in a rural province of Cambodia and investigated the impact of sample storage conditions and infant environment on microbiota composition. Faecal samples collected at three time points from 32 infants were analysed for microbiota composition using 16S rRNA amplicon sequencing and concentrations of faecal cytokines. Faecal bacterial isolates were subjected to whole genome sequencing and genomic analysis. We compared the effects of two sample collection methods due to the challenges of faecal sample collection in a rural location. Storage of faecal samples in a DNA preservation solution preserved Bacteroides abundance. Microbiota analysis of preserved samples showed that Bifidobacterium was the most abundant genus with Bifidobacterium longum the most abundant species, with higher abundance in breast-fed infants. Most infants had detectable pathogenic taxa, with Shigella and Klebsiella more abundant in infants with recent diarrhoeal illness. Neither antibiotics nor infant growth were associated with gut microbiota composition. Genomic analysis of isolates showed gene clusters encoding the ability to digest human milk oligosaccharides in B. longum and B. breve isolates. Antibiotic-resistant genes were present in both potentially pathogenic species and in Bifidobacterium. Faecal concentrations of Interlukin-1alpha and vascular endothelial growth factor were higher in breast-fed infants. This study provides insights into an underrepresented population of rural Cambodian infants, showing pathogen exposure and breastfeeding impact gut microbiota composition and faecal immune profiles.

Association between breastfeeding, mammographic density, and breast cancer risk: a review.

BACKGROUND: Mammographic density has been associated with breast cancer risk, and is modulated by established breast cancer risk factors, such as reproductive and hormonal history, as well as lifestyle. Recent epidemiological and biological findings underscore the recognized benefits of breastfeeding in reducing breast cancer risk, especially for aggressive subtypes. Current research exploring the association among mammographic density, breastfeeding, and breast cancer is sparse. MAIN FINDINGS: Changes occur in the breasts during pregnancy in preparation for lactation, characterized by the proliferation of mammary gland tissues and the development of mammary alveoli. During lactation, the alveoli fill with milk, and subsequent weaning triggers the involution and remodeling of these tissues. Breastfeeding influences the breast microenvironment, potentially altering mammographic density. When breastfeeding is not initiated after birth, or is abruptly discontinued shortly after, the breast tissue undergoes forced and abrupt involution. Conversely, when breastfeeding is sustained over an extended period and concludes gradually, the breast tissue undergoes slow remodeling process known as gradual involution. Breast tissue undergoing abrupt involution displays denser stroma, altered collagen composition, heightened inflammation and proliferation, along with increased expression of estrogen receptor α (ERα) and progesterone receptor. Furthermore, elevated levels of pregnancy-associated plasma protein-A (PAPP-A) surpass those of its inhibitors during abrupt involution, enhancing insulin-like growth factor (IGF) signaling and collagen deposition. Prolactin and small molecules in breast milk may also modulate DNA methylation levels. Drawing insights from contemporary epidemiological and molecular biology studies, our review sheds light on how breastfeeding impacts mammographic density and explores its role in influencing breast cancer. CONCLUSION: This review highlights a clear protective link between breastfeeding and reduced breast cancer risk via changes in mammographic density. Future research should investigate the effects of breastfeeding on mammographic density and breast cancer risk among various ethnic groups and elucidate the molecular mechanisms underlying these associations. Such comprehensive research will enhance our understanding and facilitate the development of targeted breast cancer prevention and treatment strategies.

A swallowing and breastfeeding intervention programme for small and sick neonates embedded in kangaroo mother care.

Available evidence of oral sensorimotor interventions for small neonates is not strong. Evidence of interventions for sick term neonates is largely lacking. Studies are limited by risk of bias and inconsistency. Evidence of interventions relying on a single stimulation technique only appears to be low to very low. Ongoing research is required.Contribution: We describe a five-component neonatal swallowing and breastfeeding intervention programme embedded in the practice of kangaroo mother care (KMC). Drawing on oropharyngeal physiology, neonatology, neurodevelopmental care, breastfeeding- and KMC science, the programme is the product of collaboration between a speech-language therapist and a medical doctor, and their team. Its implementation is dependent on coaching mothers and the neonatal care team. Researchers are invited to determine outcomes of the programme.

Human milk oligosaccharides are associated with maternal genetics and respiratory health of human milk-fed children.

Breastfeeding provides many health benefits, but its impact on respiratory health remains unclear. This study addresses the complex and dynamic nature of the mother-milk-infant triad by investigating maternal genomic factors regulating human milk oligosaccharides (HMOs), and their associations with respiratory health among human milk-fed infants. Nineteen HMOs are quantified from 980 mothers of the CHILD Cohort Study. Genome-wide association studies identify HMO-associated loci on chromosome 19p13.3 and 19q13.33 (lowest P = 2.4e-118), spanning several fucosyltransferase (FUT) genes. We identify novel associations on chromosome 3q27.3 for 6'-sialyllactose (P = 2.2e-9) in the sialyltransferase (ST6GAL1) gene. These, plus additional associations on chromosomes 7q21.32, 7q31.32 and 13q33.3, are replicated in the independent INSPIRE Cohort. Moreover, gene-environment interaction analyses suggest that fucosylated HMOs may modulate overall risk of recurrent wheeze among preschoolers with variable genetic risk scores (P < 0.01). Thus, we report novel genetic factors associated with HMOs, some of which may protect the respiratory health of children.

Psychometric evaluation of the Afaan Oromo version of the exclusive breastfeeding social support scale among Ethiopian women.

PROBLEM: There is a lack of validated tools for assessing social support for Exclusive Breastfeeding (EBF) practice in Ethiopia. BACKGROUND: Validating instruments ensures culturally appropriate and reliable data collection for effective research and interventions. AIM: This study aimed to translate the exclusive breastfeeding social support scale into the Afaan Oromo language (EBFSS-AO) and test its psychometric properties among Ethiopian women. METHODS: The scale was first subjected to forward and backward translation before undergoing psychometric evaluation. Then, a cross-sectional study was conducted on convenience sample of 160 postpartum women. Content validity was assessed via Content Validity Index (CVI), and construct validity was tested using confirmatory factor analysis (CFA) with maximum likelihood estimation. The scale's reliability was measured using Cronbach's alpha and intraclass correlation coefficient (ICC). FINDINGS: The CFA verified that the EBFSS-AO for Ethiopian women is a three-dimensional scale with satisfactory fit indices; x2/df: 2.76; Comparative fit index: 0.917; Tucker-Lewis Index: 0.902; Standardized Root Mean square residual: 0.061; and Root mean square error of approximation: 0.105. Item-level CVI ranged from 0.86 to 1.00, and scale-level CVI was 0.98. The overall scale had a Cronbach's alpha of 0.95 while instrumental, emotional, and informational support subscales had a Cronbach's alpha of 0.89, 0.92, and 0.93 respectively. After a 4-week re-test, the ICC yielded a value of 0.94. Partner support on EBF showed no socio-demographic differences except for income. CONCLUSION: The EBFSS-AO showed satisfactory psychometric properties, suitable for assessing social support among Ethiopian women in both research and clinical contexts.

Effect of Lactational Low-Protein Diet on Skeletal Muscle during Adulthood and Ageing in Male and Female Mouse Offspring.

Sarcopenia is characterised by the loss of skeletal muscle mass and function, which leads to a high risk of increased morbidity and mortality. Maternal malnutrition has been linked to impaired development of skeletal muscle of the offspring; however, there are limited studies that report the long-term effect of a maternal low-protein diet during lactation on the ageing of skeletal muscles. This study aimed to examine how a maternal low-protein diet (LPD) during lactation affects skeletal muscle ageing in the offspring. Pups born from control mothers were lactated by mothers fed with an LPD. Post-weaning, mice were either maintained on an LPD or switched to a control, normal-protein diet (NPD). In males, an LPD mainly affected the size of the myofibres without a major effect on fibre number and led to reduced grip strength in ageing mice (24 months). Female mice from mothers on an LPD had a lower body and muscle weight at weaning but caught up with control mice at 3 months. During ageing, the muscle weight, myofibre number and survival rate of female pups were significantly affected. These findings highlight the effect of an LPD during lactation on skeletal muscle ageing, the lifespan of offspring and the importance of sexual dimorphism in response to dietary challenges.

Multi-Omics Profiles of Small Intestine Organoids in Reaction to Breast Milk and Different Infant Formula Preparations.

Ensuring optimal infant nutrition is crucial for the health and development of children. Many infants aged 0-6 months are fed with infant formula rather than breast milk. Research on cancer cell lines and animal models is limited to examining the nutrition effects of formula and breast milk, as it does not comprehensively consider absorption, metabolism, and the health and social determinants of the infant and its physiology. Our study utilized small intestine organoids induced from human embryo stem cell (ESC) to compare the nutritional effects of breast milk from five donors during their postpartum lactation period of 1-6 months and three types of Stage 1 infant formulae from regular retail stores. Using transcriptomics and untargeted metabolomics approaches, we focused on the differences such as cell growth and development, cell junctions, and extracellular matrix. We also analyzed the roles of pathways including AMPK, Hippo, and Wnt, and identified key genes such as ALPI, SMAD3, TJP1, and WWTR1 for small intestine development. Through observational and in-vitro analysis, our study demonstrates ESC-derived organoids might be a promising model for exploring nutritional effects and underlying mechanisms.
