Breastfeeding Medicine

Health care trainees lack opportunities to practice breast assessment and clinical skills with patients, making breast models significant for hands-on training. Insufficient training leads to low competence across practitioners in breast health areas of practice, including clinical lactation. The aim of this review was to describe types of breast models used to teach clinical skills of the breast across breast health areas. The secondary aims were to describe education interventions that included each model and identify whether multiple skin tones were available in models.

Authors conducted a scoping review to identify which types of breast models are used to teach clinical skills across breast health areas of practice and determine gaps in literature regarding how clinical lactation skills are taught. The literature search was conducted in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, MedLine, and ProQuest. Inclusion criteria were students/professionals engaging in breast model simulation. Eighteen studies were reviewed. Authors extracted data on participants, breast health area, breast model, intervention, evaluation, general outcomes, skin tone, and research design.

The most common skill area was clinical breast exam (n = 7), while least was breastfeeding education (n = 1). Most models were commercial (n = 12). Zero studies described skin tone. Generally, breast model simulations were correlated with increased clinical skills and confidence regardless of model used.

Despite demonstrated gain of skills, this review reveals inconsistent use of breast models and evaluation, exclusion of diverse skin tones, and lack of breast models reported to teach clinical lactation skills.

Lactation support, defined here as the access to educational resources, supplies, mental health and psychosocial support, skilled lactation counseling, and peer support, has been identified as critical to optimal health outcomes for birthing parents and infants. People who give birth while incarcerated are likely to receive suboptimal lactation support. The purpose of this review is to explore the literature on lactation support for incarcerated people to identify existing programs and policies, gaps in lactation support and ways to address the gaps, and incarcerated people's perspectives on breastfeeding and lactation support.

We conducted a systematic review of the peer-reviewed literature to identify studies that addressed two main concepts: (1) breastfeeding and (2) incarcerated populations in the United States.

After meeting the eligibility criteria, 29 studies were included in the qualitative synthesis of the findings. Studies highlight the importance of supporting birthing people who want to provide milk to their infants in a way that is desired, psychologically safe, and structurally supported. Programs are needed to delay or prevent parent-infant separation after birth, provide education around breastfeeding misconceptions, and link to resources and ongoing support for both breastfeeding and milk expression. Implementation of breastfeeding programs may be most effectively undertaken with clear policies and dedicated leadership either internally or through community or health care partnerships.

This review highlights the policies and practices that hinder adequate lactation support for birthing parent-infant dyads who are incarcerated and describes feasible policies, education, and clinical support that can be used to improve care.

Breastfeeding has various benefits for infants and mothers. However, if not performed in the correct posture, prolonged breastfeeding could cause musculoskeletal-related symptoms such as shoulder, neck, and upper back pain. In Jordan, nursing mothers do not have access to a breastfeeding midwifery team, a breastfeeding dietician, or a breastfeeding nurse for advice and education. The primary aim of this study was to explore nursing mothers' experiences of breastfeeding-related musculoskeletal pain; secondary aims were to explore nursing mothers' awareness of recommended breastfeeding postures and their experience of education and advice about breastfeeding postures.

A cross-sectional mixed methods study was conducted with nursing mothers in Jordan who have breastfed their babies for 6 months or more following normal delivery, using an online survey questionnaire and semi-structured interviews. Participants were recruited through general practitioner clinics.

Four hundred ninety-three nursing mothers submitted the online questionnaire, and 12 interviews were completed. Nursing mothers reported experiencing nonspecific pain in lower back, neck, shoulder, and hand, attributed to breastfeeding. Pain in these joints affected mood, sleep, working ability, and quality of life by limiting activities of daily living. Findings showed that the majority of Jordanian nursing mothers did not receive education about safe or optimal breastfeeding positioning from health professionals.

Nursing mothers in Jordan are not receiving appropriate education or advice about optimal postures for breastfeeding and have reported experiencing musculoskeletal pain, attributed to breastfeeding, that interferes with activities of daily living and affects quality of life. Postural education and advice should be provided to nursing mothers to prevent or avoid development of musculoskeletal pain.

To determine intention to breastfeed (ITBF) rates among mothers exclusively using marijuana (eMJ) compared with electronic cigarettes (eEcig), tobacco products (eTob), or multisubstances (MS), nonusers (NU), and the influence of paternal presence and paternal substance use.

Cross-sectional study of parental survey responses merged with electronic birth certificates. Accounting for clinical and social determinants of health, analyses of ITBF included (1) all mothers, (2) single mothers, and (3) mothers with fathers.

Among all mothers (n = 1,073), eMJ, eTob, and MS users had lower odds of ITBF compared with NU. Only eMJ users had lower odds of ITBF for those without paternal presence. However, in those mothers with a paternal presence, odds of ITBF were similar to NU for eMJ, eTob, and MS users when accounting for paternal factors, including paternal substance use.

Women exclusively using MJ have lower ITBF compared with NU. However, paternal presence mitigated this effect, independent of parental MJ use. The presence of fathers may represent a unique predictor for increased ITBF in MJ using mothers.

The microbial community in human milk is associated with many maternal and neonatal factors. This study aimed to investigate the effect of antibiotic exposure on the microbial community structure of colostrum.

Twenty women with antibiotic treatment immediately after delivery and 10 age-matched control women were enrolled at the Guangdong Women and Children Hospital. Colostrum samples were collected within postpartum 30 hours. The V4 variable region of the bacterial 16S rRNA gene was sequenced to characterize the microbial profile using Illumina MiSeq platform.

Phyla Proteobacteria and Firmicutes were the predominant bacteria in colostrum samples. The core and abundant genera in colostrum included Streptococcus, Staphylococcus, and Pseudomonas. Compared with the control group, principal coordinate analysis based on the Bray-Curtis distance showed a significant difference in milk microbial community in women with antibiotic exposure, accompanied by a significantly lower alpha diversity and a different microbial ecological network. Furthermore, the relative abundances of genera Actinomyces, Anaerobacter, and Clostridium_sensu_stricto significantly decreased after antibiotic treatment.

This study provided evidence of alterations in the colostrum microbial community with antibiotic exposure, improving our understanding of the effects of antibiotic treatment on the milk microbiome.

There is little information regarding the allergen content of milk feeds in the preterm population. Previous studies have not performed a broad analysis of the allergenic peptide content and protease activity of milk feeds in this population.

To evaluate feasibility, we initially performed mass spectrometry on 4 human milk (HM) samples (2 term and 2 preterm) from the Mommy's Milk Human Milk Biorepository (HMB) and analyzed the results against the University of Nebraska FASTA database and UniProt for a total of 2,211 protein sequences. We then further analyzed five samples from the Microbiome, Atopy, and Prematurity (MAP) study including peptidomic and protease activity analysis.

Each HMB sample had between 806 and 1,007 proteins, with 37–44 nonhuman proteins/sample encompassing 26 plant and animal species. In the preterm MAP samples, 784 digested nonhuman proteins were identified, 30 were nonbovine in origin. Proteins from 23 different species including aeroallergens, food, and contact allergens were identified. Protease activity was highest in HM samples without human milk fortifier and lowest in preterm formula.

These findings represent the first preterm milk feed mass spectrometry and protease analysis with identification of known allergenic proteins to food, contact, and aeroallergens. These results raise questions of whether the composition of milk feeds in the neonatal intensive care unit impact the development of atopic disease in the preterm population and whether the complex interaction between allergens, proteases, and other HM components can serve to induce sensitization or tolerance to allergens in infants.

To study breastfeeding initiation, duration, and associated factors in patients with systemic lupus erythematosus (SLE), a cross-sectional study comparing with SLE and non-SLE mothers was conducted.

Thirty patients with SLE who had pregnancy outcomes from September 2018 to December 2020 and 120 non-SLE patients (excluding mothers with other immune system diseases) were included in the study. Data on sociodemographic, obstetric, and SLE clinical information were collected. Breastfeeding initiation, breastfeeding duration, and reasons for not initiating breastfeeding were investigated via telephone.

The rate in breastfeeding of SLE group was significantly lower than non-SLE group (36.7% versus 86.7%, respectively, p < 0.001; odds ratio 0.059; 95% confidence interval 0.015–0.241). Non-SLE mothers had a longer duration of breastfeeding than mothers with SLE (log-rank p = 0.001). Fearing of the adverse effects of drugs on babies is the main reason (68.4%) for not initiating breastfeeding in SLE group. Infants with high weight and Apgar scores, primipara women, and having a college degree were significantly associated with breastfeeding among patients with SLE.

SLE women showed a lower breastfeeding rate and shorter breastfeeding duration. Postpartum medications are safe for lactation in most patients with SLE. Targeted intervention programs that enhance breastfeeding consultations are required for this group.

Sudden unexpected infant death (SUID) rates remain higher in American Indian/Alaska Native (AI/AN) and non-Hispanic Black (NHB) infants than other demographic groups. Racial disparities are also evident in breastfeeding, which is associated with reduced risk of SUID.

To assess the relationship between racial/ethnic disparities in SUID and breastfeeding beyond the newborn period using U.S. nationally reported public databases.

Data were extracted from Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research (WONDER) and the National Immunization Surveys (NISs) 2009–2017. WONDER data were restricted to full-term infants and sorted by death year, race/ethnicity, and other characteristics. NIS breastfeeding data included ever breastfed, breastfed at 6 months, and exclusive breastfeeding at 3 and 6 months. Breastfeeding rates and mortality data were aggregated based on race/ethnicity, and mortality rates were analyzed by weighted (number of births) multivariable linear regression.

SUID rates were highest among NHB and AI/AN infants who also had the lowest breastfeeding rates. When breastfeeding and race/ethnicity were included in the analyses, race/ethnicity confounded the relationship between breastfeeding and SUID. When race was excluded, ever breastfeeding and any breastfeeding at 6 months were associated with significantly decreased SUID rates.

Race/ethnicity confounded the relationship between breastfeeding and SUID. Analysis was limited because individual SUID rates were available for maternal/birth characteristics but not for breastfeeding. Our study showed a need for adding additional data points to other national databases to better understand the role that breastfeeding plays in the racial/ethnic disparities in SUID.
