Solely human milk diets for preterm infants

Observational study showed that using video consultations was a viable way of delivering an early discharge programme for preterm infants

AIM

The aim of this study is to evaluate an early discharge programme with video consultations for preterm infants.

METHODS

A homecare programme for preterm infants was developed. Prospective data on readmissions, length of stay, growth, breastfeeding rates, and parent self-reports about satisfaction were collected from April 2021 to August 2023. Additionally, retrospective data were collected from the Norwegian Neonatal Network Central Database from 2020.

RESULTS

Preterm infants, 72 and parents, 128 were included. The infants were discharged from the hospital at a median of 35 + 6 (34 + 0-42 + 4) weeks postmenstrual age. The median length of stay in the program was 18 days (3-37). There were four readmissions. The Z-score of infant weight slightly increased during the follow up, with a mean of 0.16. By discharge, 75% of the infants were exclusively breastfed. Growth and breastfeeding rates were in line with retrospective data (85 infants). The response rate of the parents to the survey was 61 (52%). Overall, the parents (n = 54) were highly satisfied (96%). The video consultations contributed to ensuring parents to feel safe in caring for their infant at home.

CONCLUSION

Follow up by video consultations is a viable healthcare service for preterm infants, the infants' growth is sufficient, breastfeeding rates are maintained, and parents feel safe and satisfied.

Displacement of human milk during fortification: An experimental study

BACKGROUND

This study quantified the displacement of human milk by commercial human milk fortifiers (HMFs) and infant formulas.

METHODS

Commercial liquid HMFs and powder infant formulas were added to pasteurized pooled donor human milk in triplicate, stirred, and weighed. The difference in weight between unfortified and fortified human milk at 22, 24, 26, 27, 28, and 30 kcal/ounce was calculated.

RESULTS

The displacement of human milk by liquid HMFs and powder infant formulas and powder HMF was highly associated with energy density. A human milk-derived HMF displaced significantly more human milk when compared with bovine milk-derived HMFs at equivalent energy densities. Similarly, powder infant formulas displaced less human milk when compared with a powder HMF, and the addition of hydrolyzed powder infant formulas resulted in less human milk displacement when compared with nonhydrolyzed powder infant formulas.

CONCLUSIONS

The displacement of human milk by commercial liquid HMFs and infant formulas must be considered when selecting a fortifying strategy.

Pasteurized Donor Human Milk Should Not Replace Mother's Own Milk in Preterm Neonates: A Quality Initiative Toward Decreasing the "PDHM Dependency"

Aim: Mother's own milk (MOM) is the preferred source of neonatal nutrition. Due to various challenges, mothers are often unable to provide exclusive MOM to neonates admitted in neonatal intensive care units (NICUs) and depend on pasteurized donor human milk (PDHM). The aim of this quality improvement (QI) initiative was to enable mothers to provide MOM and consequently decrease the "PDHM dependency." Methods: Neonates <32 weeks of gestation (n = 120) were included. A multidisciplinary team was formed, and a detailed root cause analysis was done to understand the cause of PDHM dependency during the observation phase (November 1 to December 15, 2019). Various evidence-based practices were planned, tested, and implemented through Plan-Do-Study-Act cycles during the intervention phase (December 16, 2019 to January 31, 2020). These were further strengthened and adopted as a unit culture during the maintenance phase (February 1 to July 31, 2020). Results from the observation and intervention phases were compared. Results: Within 6 weeks of QI interventions, the average proportion of MOM significantly increased from 74.4% to 93.5% (p = 0.0003), and the proportion of PDHM significantly decreased from 20.5% to 4.6% (p = 0.005). The proportion of MOM remained at 82.5% during the maintenance phase. There was a significant decrease in the number of days to reach full feeds and regain birth weight. Conclusions: Provision of PDHM from our newly functional milk bank led to a reduced drive to express MOM in mothers of NICU babies. Our QI project focused on various strategies to improve MOM feeding and reduce PDHM dependence.

Initiation of lactation and the provision of human milk to preterm infants in German neonatal intensive care units from the mothers' perspective

Background

If infants with a very low birth weight (VLBW) are to be fed exclusively with human milk, it is essential to focus on lactation initiation. The aim of the study is to learn more about the current state of lactation initiation and human milk provision in neonatal intensive care units in Germany from the mothers' perspective.

Methods

Written surveys were conducted with mothers of VLBW infants to learn more about the timing of initiation of lactation, pumping frequency during the first three days postpartum and feeding of the preterm infant during hospitalisation.

Results

The data of 437 mothers (response rate: 44.7%) were included in the analyses. Of these, only 7.8% stated that they had initiated lactation immediately after delivery and 38.2% within 6 h. In terms of pumping frequency, 50.1% pumped 7–9 times a day within the first 3 days postpartum; 60.9% reported that their infant received formula feedings during the hospital stay.

Conclusion

Overall, deficits were still evident with regard to the initiation of lactation in mothers of VLBW infants in Germany, resulting in a large proportion of VLBW infants receiving formula in the hospital.

Human milk-based fortifier is associated with less alteration of milk fat globule size than cow milk-based fortifier

We aimed to evaluate if human milk-based fortifier (HMBF) affects human milk fat globule (MFG) size less than cow milk-based fortifier (CMBF), which may impact overall infant feeding tolerance. Measurements of donated human milk were performed before fortification as well as at 1 hour, 24 hours, and 48 hours after fortification with CMBF or HMBF. MFG size in each sample of fortified milk was measured by laser light scattering. MFG size in the fortified milks increased gradually over time. At 24 and 48 hours after fortification, MFG size in the milk with CMBF was larger than that in the milk with HMBF (4.8 ± 0.5 vs 4.3 ± 0.3 μm, p<0.01, 5.1 ± 0.7 vs 4.5 ± 0.4 μm, p = 0.03, respectively). HMBF is associated with less alteration of MFG size than CMBF. This may have an impact on feeding tolerance of very preterm infants.

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.

Secondary immunodeficiencies: An overview

OBJECTIVE

To review the different causes of secondary immunodeficiencies and provide clinicians with an updated overview of potential factors that contribute to immunodeficiency.

DATA SOURCES

Recent published literature obtained through PubMed database searches, including research articles, review articles, and case reports.

STUDY SELECTIONS

PubMed database searches were conducted using the following keywords: immunodeficiency, antibody deficiency, immunosuppressive drugs, genetic syndrome, malignancy, HIV infection, viral infection, secondary immunodeficiency, nutrition, prematurity, aging, protein-losing enteropathy, nephropathy, trauma, space travel, high altitude, and ultraviolet light. Studies published in the last decade and relevant to the pathogenesis, epidemiology, and clinical characteristics of secondary immunodeficiencies were selected and reviewed.

RESULTS

Researchers continue to investigate and report abnormal immune parameters in the different entities collectively known as secondary immunodeficiencies. Immunodeficiency might occur as a consequence of malnutrition, metabolic disorders, use of immunosuppressive medications, chronic infections, malignancies, severe injuries, and exposure to adverse environmental conditions. The neonate and the elderly may have decreased immune responses relative to healthy adults. Each of these conditions may present with different immune defects of variable severity. The acquired immunodeficiency syndrome results from infections by the human immunodeficiency virus, which targets CD4 T cells leading to defective immune responses. Rituximab is a monoclonal antibody that targets CD20 B cells, and its use might result in persistent hypogammaglobulinemia.

CONCLUSION

Clinicians should consider secondary immunodeficiencies in the differential diagnosis of a patient with recurrent infections and abnormal immunologic evaluation. The use of biological agents for the treatment of inflammatory conditions and malignancies is an increasingly important cause of secondary immunodeficiency.

Rates and Determinants of Mother's Own Milk Feeding in Infants Born Very Preterm

OBJECTIVES

To examine rates and determinants of mother's own milk (MOM) feeding at hospital discharge in a cohort of infants born very preterm within the Canadian Neonatal Network (CNN).

STUDY DESIGN

This was a population-based cohort study of infants born at <33 weeks of gestation and admitted to neonatal intensive care units (NICUs) participating in the CNN between January 1, 2015, and December 31, 2018. We examined the rates and determinants of MOM use at discharge home among the participating NICUs. We used multivariable logistic regression analysis to identify independent determinants of MOM feeding.

RESULTS

Among the 6404 infants born very preterm and discharged home during the study period, 4457 (70%) received MOM or MOM supplemented with formula. Rates of MOM feeding at discharge varied from 49% to 87% across NICUs. Determinants associated with MOM feeding at discharge were gestational age 29-32 weeks compared with <26 weeks (aOR 1.56, 95% CI 1.25-1.93), primipara mothers (aOR 2.12, 95% CI 1.86-2.42), maternal diabetes (aOR 0.79, 95% CI 0.66-0.93), and maternal smoking (aOR 0.27, 95% CI 0.19-0.38). Receipt of MOM by day 3 of age was the major predictor of breast milk feeding at discharge (aOR 3.61, 95% CI 3.17-4.12).

CONCLUSIONS

Approximately two-thirds of infants born very preterm received MOM at hospital discharge, and rates varied across NICUs. Supporting mothers to provide breast milk in the first 3 days after birth may be associated with improved MOM feeding rates at discharge.

Breastfeeding satisfaction post hospital discharge and associated factors - a longitudinal cohort study of mothers of preterm infants

Background

Mothers’ satisfaction with breastfeeding is important for breastfeeding duration but rarely investigated in mothers of preterm infants. The aim of this study was to describe breastfeeding satisfaction and associated factors during the first year in mothers of preterm infants (gestational age < 37 weeks).

Methods

This longitudinal cohort study, based on secondary analysis data from a randomized controlled trial, included 493 mothers of 547 preterm infants. Data on breastfeeding duration and satisfaction, parental stress and attachment were collected at 8 weeks post discharge, and at 6 and 12 months after birth. Breastfeeding satisfaction was measured by the Maternal Breastfeeding Evaluation Scale. Descriptive statistics and linear mixed effect models were used when analyzing the data.

Results

During the first 12 months breastfeeding satisfaction increased in the mean summary scores and points in the dimensions “role attainment” and “lifestyle and maternal body image”. In the dimension “infant growth and satisfaction”, there was an increase in mean points from 6 to 12 months after birth, but not between 8 weeks after discharge and 12 months after birth. The findings also showed that partial and no breastfeeding, higher parental stress, and infant gestational age < 32 weeks were associated with decreased breastfeeding satisfaction. Older maternal age and greater maternal attachment were associated with increased maternal breastfeeding satisfaction. There were no associations between maternal breastfeeding satisfaction and maternal educational level, parity, multiple birth, or maternal birth country other than Sweden, during the first 12 months after birth.

Conclusions

Breastfeeding satisfaction was clearly associated with breastfeeding duration during the first year after birth. Breastfeeding satisfaction may be important to take into account when supporting breastfeeding and when designing interventions to support breastfeeding. Furthermore, these findings highlight the complexity of breastfeeding and emphasize the need for early and good support during neonatal care, so that mothers feel trust in themselves and their infant and in exclusive breastfeeding at discharge and in the first months thereafter.

Trial registration

The randomized controlled trial was registered NCT01806480 with www.clinicaltrials.gov on 2013-03-07.

"Paying it Forward" - Swedish Women's Experiences of Donating Human Milk

BACKGROUND

Human milk is recommended as the only nutritional source during the first 6 months of life. For preterm infants, the benefits of human milk are even more important and can alleviate the negative influences of preterm birth.

RESEARCH AIM

To describe how Swedish human milk donors experienced the donation process.

METHOD

A prospective mixed methods mail survey was designed. It was sent to human milk donors (N = 72) at two Swedish hospitals. Quantitative data are presented with descriptive statistics and qualitative data were analyzed using qualitative content analysis.

RESULTS

The infants were between newborn and 17 weeks of age when the participants started their human milk donations, and the duration of the donation period lasted 1-24 weeks. The overall theme identified was the participants' strong desire to help infants, often expressed as being involved in saving infants' lives. Many participants experienced difficulties getting the information needed to become human milk donors; for others, expressing milk required both time and energy that they could otherwise spend with their own newborn infants.

CONCLUSION

Donating human milk can be experienced as a demanding and strenuous task. Therefore, it is important that women who donate human milk receive the practical help from health care staff that they feel they need. Furthermore, information and knowledge about the possibility of donating human milk, and how important human milk is for preterm and/or sick infants, are important in order to increase the number of women willing to donate human milk.

Human Milk-Derived Fortifiers Compared with Bovine Milk-Derived Fortifiers in Preterm Infants: A Systematic Review and Meta-Analysis

This systematic review assessed outcomes after using human milk-derived fortifier (HMF) compared with bovine milk-derived fortifier (BMF) in preterm infants. Six randomized controlled trials (RCTs) were included. Meta-analysis using a random-effects model showed the following results: 1) lower risk of necrotizing enterocolitis (NEC; ≥Stage II) (RR: 0.38; 95% CI: 0.15, 0.95; P = 0.04, I2 = 9%; n = 334, 4 RCTs) and surgical NEC (RR: 0.13; 95% CI: 0.02, 0.67; P = 0.02, I2 = 0%; n = 209, 3 RCTs) in the HMF group; 2) no significant difference in mortality (RR: 0.40; 95% CI: 0.14, 1.15; P = 0.09, I2 = 0%; n = 334, 4 RCTs); 3) lower weight gain in the HMF group [mean difference (MD) = -1.08 g · kg-1 · d-1; 95% CI: -1.96, -0.21 g · kg-1 · d-1; P = 0.02, I2 = 0%; n = 241, 4 RCTs]; 4) no differences for length (MD = -0.11 cm/wk; 95% CI: -0.26, 0.04 cm/wk; P = 0.14, I2 = 68%) and head circumference (MD = -0.02 cm/wk; 95% CI: -0.08, 0.05 cm/wk; P = 0.59, I2 = 23%); and 5) no significant difference in late-onset sepsis (RR: 0.96; 95% CI: 0.56, 1.67; P = 0.90, I2 = 63%; n = 334, 4 RCTs). The beneficial effects of HMF for NEC were no longer significant in sensitivity analyses after excluding studies with high risk of bias. Quality of evidence as per Grading of Recommendations, Assessment, Development and Evaluation (GRADE) analysis was low to very low, and hence the confidence in these results is low. In summary, fortification of milk in preterm infants with HMF compared with BMF decreased the risk of NEC but was associated with lower weight gain. Given the low quality of evidence, adequately powered and well-designed RCTs without the influence of industry are required in this field.

Implementation of the Reimbursement Cost of Human-Milk-Based Neonatal Therapy in Polish Health Care Service : Practical and Ethical Background

BACKGROUND

A human-milk-based diet is the best option for nutritional therapy for preterm and/or sick newborns.

RESEARCH AIM

The study aims were to restructure the reimbursement rates to hospitals in Poland for infants' tube feedings to favor the use of donor human milk over formula for newborns who required supplementation of expressed mother's milk and evaluate the results of the financing change during the first year of implementation (2018).

METHODS

Financial data from hospitals were collected (2015-2016) by the Human Milk Bank Foundation using a data sheet designed by the Agency for Health Technology Assessment and Tariff System. We used data to restructure the reimbursement rates to hospitals for infants' tube feedings and implemented the changes in late 2017. The National Health Fund was requested to share reported data in 2018 concerning tube feeding services.

RESULTS

More than half (61%) of NICUs introduced human milk tube feeding for newborns. It was provided to participants (N = 5,530), most frequently to seriously ill preterm infants (66.6%). Of these infants, 2,323 were fed donor human milk. Only 1,925 newborns received formula tube feeding. However, there were large differences in frequency of services reported among various parts of the country.

CONCLUSIONS

Based on our knowledge, Poland is the only European country where the reimbursement cost for human-milk-based nutritional therapy has been implemented in a manner intended to increase the quality of health care services for preterm newborns. Equal reimbursement for expressed mother's milk and donor milk did not appear to cause overuse of donor milk based on our analysis of the 2018 data.
