Milk Calcium and Phosphorus in Ugandan Women with HIV on Tenofovir-Based Antiretroviral Therapy
Journal of Human Lactation, Ahead of Print.
Background:Breastfed infants depend on human milk calcium and phosphorus for bone mineral accretion and growth. We reported greater mobilization of bone mineral and delayed skeletal recovery in lactating Ugandan women with HIV initiated on tenofovir-based antiretroviral therapy during pregnancy compared to HIV-uninfected counterparts in the Gumba Study. However, it is unknown if these disruptions in maternal bone metabolism affect milk mineral concentrations.Research Aim:To compare concentrations and patterns of change in milk calcium and phosphorus between lactating women with and without HIV.Methods:A longitudinal observational study was conducted to compare milk mineral concentrations between women with HIV receiving tenofovir-based ART and uninfected women in the Gumba Study. Milk collected at 2, 14, 26, and 52 weeks lactation was analyzed for calcium and phosphorus. Sodium and potassium were measured at 2 and 14 weeks to detect sub-clinical mastitis. Differences in milk composition between 84 women with HIV and 81 uninfected women were investigated.Results:Women with HIV had higher milk calcium than uninfected women at 14 weeks. The percent difference was +10.2% (SE = 3.0, p = .008) and there was a tendency to greater values at 2 and 26 weeks. Milk calcium decreased in both groups during lactation (p ≤ .001) but was more pronounced in women with HIV. The magnitude of change within individuals in the 1st year of lactation from 2 to 52 weeks was −28.3% (SE 3.9) versus −16.5% (SE 3.5), p for interaction = .05. Differences in milk phosphorus and calcium-to-phosphorus ratio were smaller and mostly not significant.Conclusions:Participants with HIV on tenofovir-based antiretroviral therapy had altered milk mineral composition. Studies are needed to investigate mechanisms and health implications for the woman and infant.

The Current State of Breastfeeding in Ukraine: An Interview With Lidiia Romanenko and Olha Shlemkevych
Journal of Human Lactation, Ahead of Print.
In this issue, we are featuring an interview with two medical doctors from Ukraine, who are specialists in breastfeeding, and work with the implementation of the Baby-Friendly Hospital Initiative (BFHI) in Ukraine. The authors met during the Eleventh BFHI Network Meeting of Country Coordinators from Industrialized Countries, Eastern Europe, and the Commonwealth of Independent States, in Brussels in June 2022 (Hernández-Aguilar, M. T., 2022). Ukrainian citizens have lived in a war situation since February 24, 2022, when Russia first attacked; this has had a huge impact on infant feeding issues.

“Don’t Feel Like You Have to Do This All on Your Own”: Exploring Perceived Partner Support of Breastfeeding Among Black Women in Kentucky
Journal of Human Lactation, Ahead of Print.
Background:Few researchers have explored partner breastfeeding support among Black women, who report low breastfeeding rates compared to women of other cultural groups. Ways to encourage partner support of Black women’s breastfeeding can be understood from an Afrocentric perspective.Research Aim:To explore perceptions of partner support among Black mothers to develop a culturally relevant framework of partner breastfeeding support.Methods:Secondary data analyses of qualitative data from a larger prospective, cross-sectional mixed methods study were utilized. Participants from Kentucky (N = 14), aged 23–71, who breastfed for at least 6 months, were recruited to participate in individual interviews. Professionally transcribed interviews were analyzed using Braun and Clarke’s (2006) thematic analysis.Results:By integrating the Breastfeeding Coparenting Framework and Optimal Conceptual Theory, we identified four culturally affirming partner support themes that participants believed impacted their breastfeeding experiences: (a) doing research, (b) offering care, (c) verbalizing praise, and (d) achieving teamwork, and three culturally incongruent partner support barrier themes: (e) withdrawing commitment, (f) politicking bodies, and (g) stripping agency.Conclusion:Participants who breastfed for at least 6 months largely attributed their breastfeeding success to the support received from their partners. Our findings offer a culturally relevant framework of partner breastfeeding support that can facilitate intervention efforts with participants and their partners to increase breastfeeding rates among this population.

Comparison of Lanolin and Human Milk Treatment of Painful and Damaged Nipples: A Randomized Control Trial
Journal of Human Lactation, Ahead of Print.
Background:Painful and damaged nipples are frequently associated with breastfeeding cessation in the early postpartum period. The results of researchers’ studies utilizing different treatments have been inconclusive.Research Aim:To compare the intensity of nipple pain and the healing of damaged nipples during the first 10 days postpartum using either lanolin or human milk treatments.Methods:This single-blind randomized controlled trial included participants (N = 206) who were primiparous with painful and damaged nipples. Participants were recruited from the tertiary teaching hospital within the first 72 hr after delivery and randomized to the intervention group with lanolin (n = 103) and a human milk control group (n = 103). Data were collected in the maternity ward, 3 and 7 days after randomization. The primary outcome was nipple pain intensity and quality measured 3 and 7 days after randomization by the McGill Pain Questionnaire – short form. The nipple damage self-assessment questionnaire was used for the assessment of nipple healing. Breastfeeding self-efficacy, breastfeeding duration, and exclusivity were assessed as secondary outcomes.Results:Participants in both groups reported a statistically nonsignificant reduction in pain (quality and intensity of pain) as well as improved nipple healing 7 days after randomization. Participants in the lanolin group exclusively breastfed their infants 3 days after randomization—significantly more often than participants in the control group (p = .026). The study did not reveal any statistically significant differences for other secondary outcomes.Conclusion:Both lanolin and human milk are equally effective in treating painful and damaged nipples.Registered with Clinicaltrials.gov (NCT04153513)

Increase in SARS-CoV-2 RBD-Specific IgA and IgG Antibodies in Human Milk From Lactating Women Following the COVID-19 Booster Vaccination
Journal of Human Lactation, Ahead of Print.
Background:The United States Centers for Disease Control and Prevention recommended a third dose or booster of the Pfizer-BioNTech Comirnaty (BNT162b2) COVID-19 mRNA vaccine in September 2021 for high-risk individuals. Pregnant and high-risk lactating women were encouraged to receive the booster to obtain potential prolonged protection for themselves and their infants.Research Aim:To investigate the ability of the booster vaccine to increase IgA and IgG antibodies specific to the receptor-binding domain of the SARS-CoV-2 spike protein in human milk compared to levels pre-booster.Methods:This was a prospective one-group study with a pretest-posttest design. Six of 12 participants were recruited prospectively. Participants were instructed to collect ≥ 2 ounces of milk in the morning at 30 days and 1-day pre-booster, and 7, 14, 21, 30, 45, and 60 days post-booster. Levels of IgA and IgG antibodies specific to the receptor-binding domain of the SARS-CoV-2 spike protein were quantified in human milk via an ELISA assay.Results:We found a significant increase in anti-receptor-binding domain-specific IgA and IgG antibodies in human milk 1–2 weeks after the Pfizer-BioNTech booster and at the study endpoint (45- and 60-days post-booster)Conclusions:This suggests that the booster vaccination enhances SARS-CoV-2 specific immunity in human milk, which may be protective for infants.

Infant Exposure to Armodafinil Through Human Milk Following Maternal Use of Modafinil
Journal of Human Lactation, Ahead of Print.
IntroductionNarcolepsy, a condition adversely affecting psychological, social, and cognitive function, is more prevalent in females of childbearing age than the general population. Modafinil and armodafinil are central nervous system stimulants approved for treatment of narcolepsy. Infant exposure to these agents through human milk has not been investigated. Poor quality medication safety information during lactation is associated with early cessation of breastfeeding and suboptimal healthcare for the breastfeeding family.Main IssueIn this case study, we measured the concentration of armodafinil (the most active form of modafinil) in human milk and infant plasma to quantify infant exposure.ManagementThe participant was a 30-year-old primipara with narcolepsy, taking modafinil (300 mg morning, 100 mg noon) while breastfeeding her 6-week-old infant despite the paucity of safety information. Armodafinil concentrations were measured in eight serial human milk samples collected over a 26-hr period and in single maternal and infant plasma samples using ultra performance liquid chromatography - tandem mass spectrometry. The average concentration of armodafinil in human milk was 1.96 mg/L; the relative infant dose was 4.85%; the theoretical infant dose was 0.294 mg/kg/day. Maternal and infant plasma concentrations of armodafinil were 12.02 mg/L and 0.19 mg/L, respectively. The participant continued to exclusively breastfeed the infant, who had normal growth and development.ConclusionBased on these findings, relatively small amounts of armodafinil pass into human milk, with consequent limited infant exposure. Consideration can be given to the use of modafinil or armodafinil during breastfeeding, provided the infant is monitored. Further studies are needed to confirm these findings.

Disparities in 6 Month Exclusive Breastfeeding in Ghana, Africa: A Scoping Review
Journal of Human Lactation, Ahead of Print.
Background:Exclusive breastfeeding practice for 6 months is a critical global public health goal. In 2020, only 44% of infants globally, 31% in Central and West Africa, and 43% in Ghana, were exclusively breastfed for the first 6 months of life.Research Aim:To critically evaluate disparities in exclusive breastfeeding practice for 6 months in Ghana.Methods:The scoping review was guided by Arksey and O’Malley’s (2005) six-stage scoping review process. The online databases of American Psychological Association PsychInfo (APA PsychInfo), Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, and Scopus were searched with keywords inclusive of Ghana, exclusive breastfeeding, breastfeeding, infant feeding, lactation, lactating, and exclusive. Eligibility criteria included full-text, peer-reviewed research articles written in the English language without limitation to specific years. Data were analyzed thematically.Results:Initially, 317 records were identified, and 15 full-text articles were eligible for the scoping review. Four main themes emerged as disparities in exclusive breastfeeding practice in Ghana. The themes were healthcare (prenatal clinic visits, delivery place, exclusive breastfeeding knowledge), personal (maternal age, Human Immunodeficiency Virus status, parity, type of delivery, breast problem), employment (unemployed, formal, or informal sector worker), and sociocultural (ethnicity/region, family support, religious beliefs, cultural practices).Conclusion:Disparities in exclusive breastfeeding in Ghana warrant the collaborative efforts of stakeholders for successful mitigation. Future researchers should explore the role of religion and sociocultural practices to protect, promote, and support 6 months of exclusive breastfeeding in Ghana.
