Background:Human milk expression, primarily by pump, is practiced by the majority of breastfeeding mothers in affluent countries. Existing literature is focused on determining prevalence and duration rates and the factors behind this trend. There is less research exploring mothers’ perspectives and experiences related to expression.Research aim:To gather the experiential wisdom of mothers with a focus on their information needs and sources related to human milk expression.Methods:Audiotaped interviews were conducted with 35 mothers of infants, aged birth to 24 months, who had expressed milk at least once in western Canada. This study was guided by interpretive description, an applied qualitative research approach.Results:Registered nurses and international board-certified lactation consultants were the most common sources of information, with Internet, friends/family, and other mothers also important. Inconsistent expression advice was confusing for participants, and many reported health care providers did not address all their expression learning needs. Desired topic areas included practical advice on how to express, determining expression frequency/timing/duration, milk storage guidelines, the influence of expression on milk supply, product information, and general support/encouragement.Conclusions:Assessment of expression learning needs should be part of routine lactation support at each encounter. Nonjudgmental, factual guidance will assist mothers in making evidence-informed decisions related to expression practices that are consistent with their unique breastfeeding goals. This should be supplemented by reputable online resources that provide timely and accurate information as well as efforts to connect mothers with peer support groups.

Background:Negative attitudes toward breastfeeding in public have consistently been identified as a key barrier to breastfeeding continuation. In order to design effective social marketing campaigns to improve public attitude toward breastfeeding in public, it is critical to identify segments of the population who are less likely to support this activity, their underlying reasons, and the medium through which they can be reached.Research aim:The aims were to (a) identify the underlying dimensions that drive acceptance or opposition to breastfeeding in public, (b) test whether specific population segments were more or less likely to support breastfeeding in public, and (c) identify suitable media outlets to reach them.Methods:A cross-sectional survey testing agreement with 60 statements was administered online between May 2016 and May 2017 and was completed by 7190 respondents. Exploratory factor analysis was used to identify 12 dimensions driving acceptance or opposition to breastfeeding in public. The influence of demographics and media consumption on attitudes toward breastfeeding in public was tested using Welch’s t tests and one-way analyses of variance (ANOVAs).Results:Acceptance of breastfeeding in public was found to differ with gender, age, religion, and parental and breastfeeding status, but not household income. Support for breastfeeding in public also varied with media consumption habits.Conclusions:This work lays the foundation to design effective social marketing campaigns aimed at increasing public support for breastfeeding in public.

Background:Breastfeeding women are at risk of developing mastitis during the lactation period. Staphylococcus aureus has emerged as the community-acquired pathogen responsible for virulence (methicillin resistance and Panton-Valentine leukocidin toxin producing).Research aim:The aim was to compare the microorganisms responsible for mastitis and breast abscesses during breastfeeding.Methods:This observational study was conducted with a sample of women (N = 60) admitted to our hospital between 2016 and 2018. Participants affected by mastitis and breast abscess were studied and cared for by a multidisciplinary working group. A diagnostic breast ultrasound identified the pathology.Results:Twenty-six participants (43.3%) were affected by mastitis and 34 (56.7%) by breast abscess. The most common microorganism identified was Staphylococcus aureus (S. aureus; mastitis, n = 13; abscesses, n = 24). Methicillin resistance was identified in 21 (44.7%) S. aureus strains: 17 (80.9%) cases of abscess and four (19.1%) cases of mastitis. The median number of months of breastfeeding was smaller in the methicillin-resistant S. aureus (MRSA) cases (median = 3, range = 1–20 months) than in the methicillin-sensitive S. aureus (MSSA) cases (median = 6.5, range = 3–21 months). The Panton-Valentine leukocidin toxin gene was detected in 12 (25.5%) cases (MRSA, n = 8, 66.7%; MSSA, n = 4, 33.3%). Hospitalization was required more frequently in MRSA (n = 8, 38%; five Panton-Valentine leukocidin positive) than in MSSA cases (n = 5, 19%; one Panton-Valentine leukocidin positive). Four women out of the eight MRSA cases (50%) that were Panton-Valentine leukocidin positive stopped breastfeeding during mammary pathologies, three (37.5%) participants continued breastfeeding until the follow-up recall, and one case was lost at follow-up.Conclusion:Clinical severity was probably complicated by the presence of the Panton-Valentine leukocidin toxin, which required hospitalization more frequently.
