"I Felt Like I Was a Part of Trying to Keep My Baby Alive": Perspectives of Hispanic and Non-Hispanic Black Mothers in Providing Milk for Their Very Preterm Infants

Point-of-care human milk concentration by passive osmosis: comprehensive analysis of fresh human milk samples

OBJECTIVE

Preterm infants need enrichment of human milk (HM) for optimal growth. This study evaluated a novel, point-of-care human milk concentration (HMC) process for water removal from fresh HM samples by passive osmotic concentration.

STUDY DESIGN

Nineteen fresh HM samples were concentrated by incubation with the HMC devices for 3 h at 4 °C. Pre- and post-concentration HM samples were compared by HM properties for: pH, osmolality, macronutrients, enzyme activity, bioactive, and total cell viability.

RESULTS

Passive osmotic concentration reduced HM volume by an average of 16.3% ± 3.8% without a significant effect on pH or cell viability. Ten of the 41 HM components did not differ significantly (p > 0.05) between pre- and post-concentration samples. Twenty-three increased within the expected range by volume reduction. Six increased more than expected, two less than expected, and none decreased significantly.

CONCLUSION

Passive osmotic concentration of fresh HM can concentrate HM components by selective removal of water. HM osmolality and pH remained within neonatal feeding parameters.

Mothers' experiences of breast milk expression during separation from their hospitalized infants: a systematic review of qualitative evidence

BACKGROUND

Mother-infant separation, which is occurring with an increasing incidence, is a barrier to direct breastfeeding. Owing to the importance of breast milk to hospitalized infants, mothers are actively encouraged to express milk during their infants' neonatal intensive care unit (NICU) stay. However, mothers are often faced with a number of challenges in this process. There is a need to understand such mothers' real-life experiences of breast milk expression to develop supportive strategies to reduce the burden on mothers and increase breastfeeding rates.

METHODS

A comprehensive search of 12 databases was conducted for relevant studies published from database construction to December 2022. All qualitative and mixed-method studies published in English and Chinese that reported on mothers' experiences of human milk expression during separation from their hospitalized infants were included. Two reviewers independently conducted screening, data extraction, and quality appraisal, with disagreements resolved by a third reviewer. The process of searching followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The JBI Qualitative Assessment and Review Instrument was used to assess study quality and the credibility of study findings. Meta-aggregation was performed to integrate the results.

RESULTS

This systematic review aggregated mothers' experiences of milk expression during separation from their hospitalized infants. Database search yielded 600 records, of which 19 full-text documents were screened. Finally, 13 studies of good quality were included with data from 332 mothers across seven countries. A total of 61 primary findings with illustrations were extracted from the 13 eligible studies, the findings were generalized into 16 categories, and further were concluded as four synthesized findings: purpose and motivation, physical and emotional experiences, barrier factors, and coping styles.

CONCLUSION

Mothers were driven by extrinsic motivation in their decision to express breast milk. They experienced physical exhaustion and many negative emotional feelings while expressing. This process was affected by numerous barriers. Social support was essential to the initiation and maintenance of milk expression. Medical staff and families should pay more attention to the mental health of mothers with infants in the NICU. Future research should incorporate strategies to cope with emotional responses and offer practical strategies for managing milk expression.

'We are suffering. Nothing is changing.' Black mother's experiences, communication, and support in the neonatal intensive care unit in the United States: A Qualitative Study

OBJECTIVES

Black mothers experience markedly disproportionate maternal morbidity and mortality in the United States, with racism often cited as the root cause manifesting through several pathways. The study examined Black mothers' perceived provider communication, support needs, and overall experiences in the neonatal intensive care unit (NICU).

DESIGN

This study used grounded theory embedded in the Black feminist theoretical (BFT) framework to generate new ideas grounded in the data. Data was collected through semi-structured interviews using videoconferencing, with questions related to the mother's overall NICU experiences, communication within the NICU, and perceived support needs. Data were analyzed using thematic analysis.

RESULTS

Twelve mothers participated in the study; most were married (n = 10), had a cesarean birth, had a previous pregnancy complication (e.g., diabetes, hypertension), had attained a graduate degree or more (n = 9), earned an annual household income of $75,000 or more, and were between 35-44 years of age (n = 7). Three broad domains with several accompanying themes and sub-themes were identified, explicating the mother's experiences in the NICU. Specifically, factors influencing NICU hospitalization for mothers included maternal care/nursing experiences, interactions in the NICU, and the perceived support need that might attenuate negative care and birthing experiences. .

CONCLUSION

The study adds to the growing literature championing Black maternal health equity and multilevel quality improvement strategies to foster equitable maternal health. Our study reinforces the need for racially congruent interventions and policy reformations to protect Black birthing people regardless of socioeconomic factors and social class using life course, holistic approaches, and intersectionality mindset. Importantly, using the BFT, this study calls for culturally sensitive research to capture the nuances associated with the multiplicity of experiences of Black people.

The effect of orally consumed Lactuca sativa syrup on human milk volume and weight gain in the preterm infant: a randomized controlled clinical trial

Human milk feeding can support premature infants to thrive. Yet those with premature infants can be challenged in human milk production. Considering this, and the use of potentially harmful human milk enhancers, the present study was conducted with the aim of determining the effect of orally consumed Lactuca sativa (L. sativa) syrup (lettuce extract) on human milk volume and subsequent weight gain in the preterm infant. Extracts from lettuce and other plants such as silymarin are already evidenced to be safe for use during lactation and have other therapeutic effects in humans. Yet this is the first study of its kind. This parallel randomized clinical trial included lactating participants with their preterm infants who were born at < 32 weeks' gestation and admitted to an intensive care unit. Convenience sampling was used to recruit participants. Eligible participants were allocated to groups randomly: intervention (n = 47), placebo (n = 46), and control (n = 47). The intervention group received one tablespoon of Lactuca sativa (L. sativa) syrup, and the placebo group received one tablespoon of placebo syrup 3 times a day for 1 week. Those in the control group did not receive any herbal or chemical milk-enhancing compounds. Routine care was provided to all three groups. Participants recorded their milk volume for 7 days in a daily information recorder form. Infant weight was measured prior to the intervention, and on the third, fifth and seventh days of the intervention period. There was a statistically significant difference observed in the adjusted mean volume of milk on the fourth and fifth days between the intervention, placebo, and control groups (P < 0.05). The adjusted mean milk volume of those in the intervention group on the first day was significantly higher than those in the control group and those in the placebo group. On the second day, the adjusted mean milk volume of those in the intervention group was higher than in those from the control group; and on the fourth day it was higher than in those from both the control and placebo groups; on the fifth day it was higher than in those in the placebo group; on the sixth day it was higher than in those in the control group and on the seventh day it was higher than in those in the control group (P < 0.05). There was no statistically significant difference in terms of the mean changes (with or without adjustment) in the weight of preterm infants between any of the groups. Lactuca sativa (L. sativa) syrup increases the volume of human milk production and no specific side effects have been reported in its use. Therefore, Lactuca sativa syrup can be recommended for use as one of the compounds that increase human milk volume.

From Expressing Human Milk to Breastfeeding-An Essential Element in the Journey to Motherhood of Mothers of Prematurely Born Infants

BACKGROUND

Lactation and breastfeeding present an extraordinary challenge for mothers of prematurely born infants.

PURPOSE

To explore the significance of and the circumstances that affect lactation for mothers of premature infants.

METHODS

A qualitative exploratory study based on single, in-depth, semistructured interviews with 16 purposefully sampled mothers of premature infants admitted to the neonatal intensive care unit (NICU). Data were analyzed using content analysis. The study was reported according to Standards for Reporting Qualitative Research.

FINDINGS

The overall theme was "From expressing human milk to breastfeeding-an essential element in the journey to motherhood." The theme emerged from 3 categories: the birth preparation time has been interrupted; expressing human milk is essential for lactation; and the motherhood journey encompasses breastfeeding. The analysis also revealed that the categories were impacted by initiating, performing, and maintaining lactation and further influenced by inhibitors and promoters.

IMPLICATIONS FOR PRACTICE

The promoters for performing milk expression and breastfeeding should be stimulated and the inhibitors should be eliminated. The achievement of "zero separation" and mother-infant couplet care in the NICU would be beneficial. In order for mothers to maintain successful lactation, it is essential that they receive supportive around-the-clock access to health professionals with expertise in lactation and breastfeeding until exclusive breastfeeding is well established.

IMPLICATIONS FOR RESEARCH

The study highlights the need to investigate mother-infant as one entity rather than separately as mother and infant.

Do Interventions Improve Symptoms Among ICU Surrogates Facing End-of-Life Decisions? A Prognostically-Enriched Systematic Review and Meta-Analysis

OBJECTIVES

Evaluate the efficacy of interventions to improve symptoms for ICU surrogates at highest risk of developing psychologic distress: those facing end-of-life care decisions.

DATA SOURCES

MEDLINE, CINAHL, PsycInfo, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched through April 16, 2022.

STUDY SELECTION

Following an a priori protocol, randomized trials of interventions delivered to surrogates of adult ICU patients who died or had high likelihood of mortality evaluating surrogate symptoms were identified.

DATA EXTRACTION

Two reviewers performed screening and data extraction and assessed risk of bias (Cochrane Risk of Bias [RoB] 2 tool). Trials were eligible for meta-analysis if group mean symptom scores were provided at 3 or 6 months. Pooled effects were estimated using a random effects model. Heterogeneity was assessed (Cochrane Q, I2 ). Certainty of evidence was assessed (Grading of Recommendations Assessment, Development and Evaluation).

DATA SYNTHESIS

Of 1,660 records, 10 trials met inclusion criteria representing 3,824 surrogates; eight were included in the meta-analysis. Overall RoB was rated Some Concerns. Most ( n = 8) interventions focused on improving communication and enhancing psychologic support in the ICU. All trials measured anxiety, depression, and posttraumatic stress. Significant improvement was seen at 3 months (depression, mean difference [MD], -0.68; 95% CI, -1.14 to -0.22, moderate certainty; posttraumatic stress, standardized MD, -0.25; 95% CI, -0.49 to -0.01, very low certainty) and 6 months (anxiety, MD, -0.70; 95% CI, -1.18 to -0.22, moderate certainty). Sensitivity analyses suggest significant findings may be unstable. Subgroup analyses demonstrated differences in effect by trial location, interventionist, and intervention dose.

CONCLUSIONS

Communication and psychological support interventions in the ICU yielded small but significant improvement in psychological symptoms with moderate to very low certainty evidence in a prognostically-enriched sample of ICU surrogates facing end-of-life care decisions. A new approach to interventions that extend beyond the ICU may be needed.

Strategies to Improve Mother's Own Milk Expression in Black and Hispanic Mothers of Premature Infants

BACKGROUND

Mother's own milk (MOM) is the gold standard of nutrition for premature infants. Yet, Hispanic and Black preterm infants are less likely than their White counterparts to receive MOM feedings. Evidence is lacking concerning potential modifiable factors and evidence-based strategies that predict provision of MOM among minority mothers of premature infants.

PURPOSE

A review of the literature was conducted to answer the clinical question: "What evidence-based strategies encourage and improve mother's own milk expression in Black and Hispanic mothers of premature infants?"

METHODS/SEARCH STRATEGY

Multiple databases including PubMed, Cochrane, and CINAHL were searched for articles published in the past 10 years (2010 through May 2020), reporting original research and available in English. Initial search yielded zero articles specifically addressing the impact of lactation interventions on MOM provision in minority mothers. Additional studies were included and reviewed if addressed breastfeeding facilitators and barriers (n = 3) and neonatal intensive care unit breastfeeding support practices (n = 7).

FINDINGS/RESULTS

Current strategies used to encourage and improve MOM expression in minority mothers are based on or extrapolated from successful strategies developed and tested in predominantly White mothers. However, limited evidence suggests that variation in neonatal intensive care unit breastfeeding support practices may explain (in part) variation in disparities and supports further research in this area.

IMPLICATIONS FOR PRACTICE

Neonatal intensive care unit staff should consider implementing scaled up or bundled strategies showing promise in improving MOM milk expression among minorities while taking into consideration the cultural and racial norms influencing breastfeeding decisions and practice.

IMPLICATIONS FOR RESEARCH

Experimental studies are needed to evaluate the effectiveness of targeted and culturally sensitive lactation support interventions in Hispanic and Black mothers.

Lived experiences of stress of Black and Hispanic mothers during hospitalization of preterm infants in neonatal intensive care units

OBJECTIVE

To characterize the lived experiences of stress associated with having a preterm infant hospitalized in the NICU among Black and Hispanic mothers.

METHODS

We performed a qualitative content analysis of secondary data from two prior studies that included 39 in-depth interviews with Black and Hispanic mothers of preterm infants at 3 U.S. NICUs. We used a constant comparative method to select important concepts and to develop codes and subsequent themes.

RESULTS

Black and Hispanic mothers described stressors in the following domains and categories: Individual (feeling overwhelmed, postpartum medical complications, previous stressful life events, competing priorities); Hospital (perceived poor quality of care, provider communication issues, logistical issues); Community (lack of social supports, lack of financial resources, work challenges).

CONCLUSIONS

The findings of this study suggest that stressors both inside and outside of the hospital affect the lived experiences of stress by Black and Hispanic mothers during NICU hospitalization.

Positive breastfeeding experiences and facilitators in mothers of preterm and low birthweight infants: a meta-ethnographic review

Background

Most qualitative research on breastfeeding the preterm or low-birthweight (LBW) infant has focused on negative insights; there are no comprehensive insights into how, when and why mothers experience positive breastfeeding experiences. We aimed to address this knowledge gap by exploring what characterizes and facilitates a positive breastfeeding experience in mothers of preterm and/or LBW infants.

Methods

A systematic review using meta-ethnographic methods was conducted. Search strategies involved a comprehensive search strategy on six bibliographic databases, citation tracking and reference checking. The analysis involved a reciprocal level of translation and a line of argument synthesis.

Results

Searches identified 1774 hits and 17 articles from 14 studies were included, representing the views of 697 mothers. A positive breastfeeding experience was identified as being ‘attuned’. Three themes and eight sub-themes were developed to describe what characterizes attuned breastfeeding. ‘Trusting the body and what it can do’, concerned how attuned breastfeeding was facilitated through understanding the bodily responses and capacity and feeling comfortable with holding the infant and to breastfeed. ‘Being emotionally present – in the here and now’ described the importance of feeling relaxed and reassured. ‘Experiencing mutual positive responses’, illuminated how attunement was related to feelings of mutuality - when the mother recognises the infant’s cues, responds to these signals and receives a positive response from the infant. The key factors to facilitate attuned breastfeeding were opportunities for prolonged close physical contact with the infant, positive relationships with and support from staff and peers, and being facilitated to breastfeed when the infant showed feeding cues.

Conclusions

This study provides new insights into what characterizes a positive breastfeeding experience and how staff can facilitate and enable mothers to achieve attuned breastfeeding. Improvements in units’ design, such as for rooming-in and having prolonged skin-to-skin contact, and care provided by knowledgeable, supportive and encouraging staff and peers, are crucial. The mother’s physical and emotional states and the infant’s behavioural responses and physiological signals should guide the process towards positive breastfeeding practices.

Promoting Human Milk and Breastfeeding for the Very Low Birth Weight Infant

Provision of mother's own milk for hospitalized very low birth weight (VLBW) (≤1500 g) infants in the NICU provides short- and long-term health benefits. Mother's own milk, appropriately fortified, is the optimal nutrition source for VLBW infants. Every mother should receive information about the critical importance of mother's own milk to the health of a VLBW infant. Pasteurized human donor milk is recommended when mother's own milk is not available or sufficient. Neonatal health care providers can support lactation in the NICU and potentially reduce disparities in the provision of mother's own milk by providing institutional supports for early and frequent milk expression and by promoting skin-to-skin contact and direct breastfeeding, when appropriate. Promotion of human milk and breastfeeding for VLBW infants requires multidisciplinary and system-wide adoption of lactation support practices.

Understanding Factors Influencing Breastfeeding Outcomes in a Sample of African American Women

OBJECTIVES

Persistent disparities in breastfeeding rates among African American (AA) women compared to other population groups have motivated researchers to understand factors influencing breastfeeding choices using a variety of methods. Quantitative surveys are more commonly reported, however, qualitative work that amplifies voices of AA women is limited.

METHODS

Participants were recruited from a randomized controlled feasibility trial focused on breastfeeding support for AA women in Detroit, MI. Thirteen women were enrolled in the qualitative portion of the study described here. Using the Socioecological model (SEM) as the theoretical foundation, semi-structured qualitative interviews were conducted to explore perceived facilitators and barriers to breastfeeding. Interviews were digitally recorded, transcribed, and analyzed using Theoretical thematic analysis.

RESULTS

Women reported factors ranging from micro to macro SEM levels that discouraged or reinforced breastfeeding. Key challenges included breastfeeding-related discouragement issues, including factors that decreased confidence and led women to terminate breastfeeding (e.g., problems with latching, pumping, lack of comfort with breastfeeding in public, and work constraints). Facilitators included perceived mother and infant benefits, perseverance/commitment/self-motivation, pumping ability, and social support. Participant suggestions for expanding breastfeeding promotion and support included: (1) tangible, immediate, and proactive support; (2) positive non-judgmental support; (3) "milk supply" and "use of pump" education; and (4) self-motivation/willpower/perseverance.

CONCLUSIONS FOR PRACTICE

Despite the identification of common facilitators, findings reveal AA women face many obstacles to meeting breastfeeding recommendations. Collaborative discussions between women and healthcare providers focused on suggestions provided by AA women should be encouraged.

Use of the Theory of Planned Behavior Framework to Understand Breastfeeding Decision-Making Among Mothers of Preterm Infants

Background: Mothers of preterm infants face significant challenges to breastfeeding. The theory of planned behavior (TPB) is a well-known framework comprising three domains (attitudes, perceived control, and social norms), which has been used to conceptualize the array of factors that influence health-related behaviors and develop interventions to promote behaviors. Aim: We used the TPB framework to determine the array of factors that contribute to breastfeeding among mothers of preterm infants. Materials and Methods: Using qualitative research methods, we conducted in-depth, semistructured interviews with mothers regarding their experiences feeding their preterm infants according to TPB domains. We developed themes based on an iterative process of review of transcripts and conducted interviews until thematic saturation was reached. Results: We interviewed 23 mothers in 3 states 2 to 6 months after hospital discharge; 22 mothers initiated milk production and 6 were breastfeeding at the time of the interview. Factors that were positive and negative toward breastfeeding were present for all three TPB domains. Regarding attitudes, mothers felt that breastfeeding was a way to bond, that breast milk was healthy and protective, and that breast milk alone was insufficient for a growing preterm infant. Regarding perceived control, mothers felt empowered to breastfeed due to encouragement from hospital staff, friends, and family, and had difficulty overcoming their infant's immature oral feeding skills, competing responsibilities, and perceived infant preference for bottle feeding. Regarding social norms, mothers reported support for and against breastfeeding among hospital and Special Supplemental Nutrition Program for Woman, Infants, and Children (WIC) providers, family, friends, and the media. Conclusion: Interventional studies geared toward breastfeeding promotion among mothers of preterm infants may focus on addressing barriers to direct breastfeeding during the neonatal intensive care unit and early post-discharge time periods.

"It was all taken away": Lactation, embodiment, and resistance among mothers caring for their very-low-birth-weight infants in the neonatal intensive care unit

The prevalence of infants born before 37 weeks of gestation continues to rise in the United States. Advances in neonatology have led to improved survival rates among preterm infants, including those born at a very-low-birth-weight (VLBW). Exclusive human milk feeding is a therapeutic intervention for VLBW preterm infants, and mothers are encouraged to provide their own milk. Yet, it is well-established that mothers and infants may face extraordinarily complicated lactation and infant feeding challenges in NICU settings, many of which emanate from birth trauma. The purpose of this study is to gain a deeper understanding of the ways in which the hyper-medicalized management of preterm birth and infant feeding in NICU environments affect mothers' postpartum health and well-being. Seventeen mothers of VLBW preterm infants were interviewed August 2016-June 2017 within three years of their infant's NICU discharge about their feeding decisions and experiences. Narrative analysis yielded five themes: (1) the physical and emotional trauma of giving birth prematurely impacted mothers' lactation experiences; (2) separation from their infants intensified mothers' suffering and disrupted lactation; (3) mothers experienced being marginalized in their infant's NICU care; (4) mothers practiced embodied forms of resistance to cope with both trauma and marginalization; and (5) skilled support was central to mothers' positive lactation experiences in the NICU. We draw upon feminist theory in the anthropology of reproduction to examine the fundamental hierarchies of power in U.S. neonatal critical care systems that fracture mothers' interembodied relationships to their newborns, exacerbate lactation failure, and engender traumatic postpartum neglect. Moreover, we theorize mothers' expressions of suffering in the context of preterm birth and lactation insufficiency as idioms of distress engendered by the violence of neglectful care. Narrative inquiry is instrumental to designing structural transformations in the systems of care available to mothers of preterm infants who are admitted to a NICU.

A qualitative cross-cultural analysis of NICU care culture and infant feeding in Finland and the U.S

BACKGROUND

The benefits of family-centered care for the health and well-being of preterm infants and their families include increased parent-infant closeness, improved lactation, and positive mental health outcomes; however, it is known that the extent to which family-centered care is adopted varies by unit. This study aimed to understand how differences in neonatal care culture in two units in Finland and the U.S. were translated to parents' infant feeding experiences in the hope of improving relationally focused feeding practices in both locations.

METHODS

This qualitative, cross-sectional study utilized narrative methodologies to understand the lived experiences of 15 families hospitalized in a tertiary neonatal intensive care unit in Finland (n = 8) and the U. S (n = 7).

RESULTS

A global theme of lactation as a means or an end showed that lactation and infant feeding were framed differently in each location. The three supporting themes that explain families' perceptions of their transition to parenthood, support as a family unit, and experience with lactation include: universal early postnatal challenges; culture and space-dependent nursing support; and controlled or empowering breastfeeding experiences.

CONCLUSIONS

Care culture plays a large role in framing all infant caring activities, including lactation and infant feeding. This study found that in the unit in Finland, breastfeeding was one method to achieve closeness with an infant, while in the unit in the U.S., pumping was only an end to promote infant nutritional health. Therefore, breastfeeding coupled with closeness was found to be supportive of a salutogenic, or health-promoting, care approach for the whole family.
