In 2015, Miriam Labbok, MD, MPH, entrusted Chele Marmet with the task of writing a chapter on the early history of the lactation consultant profession for the public health textbook she was preparing about lactation, saying, “I invited you to author it because you conceptualized and pioneered the profession, and there is nobody else I could ask who could do it justice,” (M. Labbok, personal communication, June 28, 2015). Chele Marmet envisioned the allied health field of lactation consulting, complete with international educational standards, professional organizations, and a scope of practice. She was an active contributing founder of the International Lactation Consultant Association, developed hundreds of test questions for the early International Board of Lactation Consultant Examiners (IBCLE), and co-founded the first academic (BA and MA) lactation education program, The Lactation Institute, to name only a few of her many innovations and contributions to the field of lactation we know today—a field that has grown exponentially globally since those early days in the 1970s when Chele began creating our profession. Her academic background in speech and hearing gave her the orientation to delve into infants’ oral-motor function. Additional education and experience followed as her passion for helping breastfeeding families grew. This is the first part of her interview; the second part will follow in the next JHL issue. Fortunately, Chele is working on her memoir, which will detail topics we could only briefly discuss in this interview. It was my honor to interview Chele Marmet.Joan E. Dodgson

Background:Disparities in breastfeeding rates and exclusivity exist across regions and countries despite multifaceted breastfeeding promotion efforts in recent decades. Markets for artificial milk formula continue to grow as its substitution for breastfeeding is common. A new approach is needed for breastfeeding promotion strategies.Research Aim:This state-of-the-art review aimed to describe the implications of not-breastfeeding on the environment within the context of food system sustainability.Method:A total of 19 peer-reviewed articles within a 20-year timeframe were included in this review. Authors searched five databases for articles including Science Direct, GreenFILE, Springer Link, ProQuest, and PubMed.Results:The demand for artificial milk formula production as a replacement for breastfeeding results in increased greenhouse gas emissions, water pollution, and waste, thereby aggravating problems with freshwater scarcity. A short duration of breastfeeding and limited exclusivity have been associated with close birth spacing and contributing to global population growth. Breastfeeding is a healthy, sustainable diet, and a culturally acceptable first food. It advances health equity and food security. Exclusive breastfeeding for the first 6 months of life can be promoted with emphasis on total carbon footprint reduction, prevention of waterway degradation, and natural birth spacing, thereby sustaining food systems at large.Conclusion:It is important to reform food, nutrition, and environmental policies to protect exclusive breastfeeding while decarbonizing artificial milk formula production. More research is needed to provide directions for new breastfeeding promotion strategies connecting breastfeeding with environmental stewardship.

Background:Infant feeding interventions that promote and support breastfeeding are considered important contributions to global public health. As these interventions often target private settings (e.g., individuals’ homes) and involve vulnerable populations (e.g., pregnant women, infants, and underprivileged families), a keen awareness of ethical issues is crucial.Research Aim:The purpose of this scoping review was to capture the key elements of the current ethical discourse regarding breastfeeding and lactation interventions.Method:A scoping review was conducted using Arksey and O’Malley’s (2005) methodology to identify the ethical issues of breastfeeding and lactation interventions as they are reflected in the scholarly literature published between January 1990 and October 2022. Abstracts (N = 3715) from PubMed, ScienceDirect, JSTOR and the Cochrane Database of Systematic Reviews were screened. The final sample consisted of 26 publications.Results:The recurring ethical issues identified in these studies were: the normative assumptions of motherhood; maternal autonomy and informed choice; information disclosure, balancing risks and benefits, and counseling practices; stigma and social context; ethics of health communication in breastfeeding campaigns; and the ethical acceptability of financial incentives in breastfeeding interventions.Conclusion:This review illustrated that, while a wide range of ethical arguments were examined, the emphasis has been primarily on accounting for mothers’ experiences and lactating persons’ choices, as well as achieving public health objectives relating to infant nutrition in breastfeeding interventions. To effectively and ethically implement breastfeeding and lactation interventions, we must consider the social, economic, and cultural contexts in which they occur. One key learning identified was that women’s experiences were missing in these interventions and, in response, we suggest moving beyond the dichotomous approach of individual health versus population health.

Background:Toxic trace elements could enter human milk through mothers’ food consumption, drinking water, air, or incidental soil ingestion, and are of concern to the nursing infant.Research Aim:To determine the concentration of toxic trace elements (lead and arsenic) in Peruvian mothers’ milk and their association with blood concentrations in their own infants 3–20 months old.Method:This exploratory, cross-sectional study, carried out in Peru, included breastfeeding mother/child dyads (N = 40). Following standardized protocols, biospecimens of human milk and child’s blood were collected.Results:Lead and arsenic concentrations in milk were above the method detection limits in 73% and 100% of samples with median concentrations of 0.26 µg/L (IQR = 0.10, 0.33 µg/L) and 0.73 µg/L (IQR = 0.63, 0.91 µg/L), respectively. Concentrations of lead and arsenic in blood were 2.05 µg/dL (SD = 1.35), and 1.43 µg/dl (geometric mean: SD = 1.39), respectively. Blood lead concentrations in 12.5% (n = 5) of the samples were above the U.S. Center for Disease Control and Prevention reference value (< 3.5 µg/dl), and over half of arsenic concentrations were above the acceptable levels of < 1.3 µg/dl (Mayo Clinic Interpretative Handbook). Our results showed that for every one-month increase in age, lead blood concentrations increased by 0.1 µg/dl (p = 0.023). Additionally, every 1 µg/L increase in the mother’s milk arsenic was associated with a 1.40 µg/dl increase in the child’s blood arsenic concentration.Conclusions:Implementing effective interventions to decrease the toxic exposure of reproductive-aged women is needed in Peru and worldwide.

Introduction:Non-puerperal adoptive lactation sometimes requires long preparation and substantial expense for pharmacological intervention to be successful, which are not feasible in refugee camps. Here we report two case studies of non-puerperal adoptive breastfeeding of two infants in the Rohingya Refugee Camp of Cox’s Bazar, Bangladesh.Main Issue:Two non-pregnant, non-breastfeeding caregivers with previous experience of breastfeeding brought two adopted infants—one a 12-day-old female with severe acute malnutrition, and the other a 2-day-old male with normal anthropometric measurements—to a nutritional stabilization center for feeding. After counseling, both families opted for adoptive lactation.Management:Both infants were treated with a modified Action Against Hunger protocol of in-patient management of severe acute malnutrition using the supplementary suckling technique, a procedure to feed the baby with supplementary feed. Diluted F100 was used as the supplementary feed; the energy and protein gained from it were just enough to maintain body physiology and were not responsible for any weight gain. When the infants gained weight, indicating that the caregivers were producing milk, we reduced the supplementary feed as per protocol guidelines. The caregivers were prescribed domperidone and counseled on their ability to breastfeed the infants. The cases required 35 days and 20 days, respectively, for the full establishment of breastfeeding.Conclusion:This is the first report of successful adoptive breastfeeding in a refugee camp. With proper counseling and motivation of the caregiver, induced lactation can be started without a preparatory period and with very low-cost intervention.

Background:Breastfeeding behaviors and experiences exist on a continuum. What differentiates normal from dysfunctional is defined by frequency and severity. No current validated tool addresses the subjective experience of dyads with a predictive score that can be followed over time.Research Aim:To create and validate a self-report tool to assess breastfeeding and evaluate its ability to predict risk of breastfeeding dysfunction.Methods:This study used a cross-sectional design to determine the validity of a novel instrument to assess breastfeeding dysfunction. We gave the initial questionnaire to 2085 breastfeeding dyads. We assessed content validity by comparison with other tools. We used exploratory factor analysis with varimax rotation for concept identification and Cronbach’s alpha for internal consistency. We employed logistic regression to assess the tool’s ability to differentiate between normal breastfeeding and breastfeeding dysfunction.Results:Factor analysis mapped 17 questions to four concepts to create a score (FLIP; flow, latch, injury [to the nipple], and post-feed behavior). Internal consistency and reliability of the scores in these concepts were acceptable (Cronbach’s alpha ≥ 0.087 for all measures). A logistic regression model that controlled for infant age, with a breastfeeding dysfunction risk classification threshold of 60%, yielded a correct classification of 88.7%, with 93.1% sensitivity, 64.6% specificity, and a 6.5% false positive rate.Conclusions:The FLIP score was determined to be a valid and reliable instrument for quantifying the severity of breastfeeding dysfunction in children under 1 year old. Further studies will assess its usefulness in the management of breastfeeding dysfunction.

Background:Breastfeeding among lactating people with opioid use disorder taking buprenorphine monotherapy is generally accepted, as low concentrations of buprenorphine and metabolites in human milk have been well-established. The use of buprenorphine-naloxone for pregnant and lactating people with opioid use disorder is expanding and there is no information available regarding the concentrations of naloxone and their metabolites in human milk to recommend the use of this combination medication during lactationResearch Aims:To determine the concentrations of buprenorphine and naloxone and their primary metabolites in human milk, maternal plasma, and infant plasma, among lactating buprenorphine-naloxone maintained people and their infants.Methods:Four lactating buprenorphine-naloxone maintained people provided plasma and human milk samples on Days 2, 3, 4, 14, and 30 postpartum. Infant plasma was obtained on Day 14.Results:Concentrations of buprenorphine, norbuprenorphine and their glucuronide metabolites were present in maternal plasma and human milk at low concentrations, consistent with previous research in lactating buprenorphine monotherapy participants. Naloxone was not detected, or was detected at concentrations below the limit of quantification, in maternal plasma and in all except one human milk sample at Day 30. Naloxone was not detected or detected at concentrations below the limit of quantification in all infant plasma samples.Conclusion:Results support the use of buprenorphine-naloxone by lactating people who meet appropriate criteria for breastfeeding.
