Breastfeeding, Human Milk and COVID-19-What Does the Evidence Say?

[Perinatal and neonatal management plan for prevention and control of SARS-CoV-2 infection (3rd Edition)]

Since the global pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2020, the virus has been evolving through mutations to acquire enhanced infectivity but reduced virulence. With a wide vaccination coverage among Chinese population, China is entering a new stage of SARS-CoV-2 infection control. The Working Group for the Prevention and Control of Neonatal SARS-CoV-2 Infection in the Perinatal Period of the Editorial Committee of Chinese Journal of Contemporary Pediatrics released the first and second editions of perinatal and neonatal management plan for prevention and control of SARS-CoV-2 infection in January and March 2020, respectively. In order to follow up new prevention and control needs, it is necessary to update the management plan to better guide clinical practice. Therefore, the Working Group formulated the 3rd-edition plan.

Impact of the Covid-19 Pandemic on Breastfeeding Establishment in Preterm Infants: An Exploratory Study

Purpose: To evaluate breastfeeding outcomes in preterm infants born during the Covid-19 pandemic. Design: An observational cohort study of 33 infants born ≤34 weeks' gestation was conducted. Sample: The study sample consisted of 33 infants divided into 2 groups: infants born during the Covid-19 pandemic (Covid group, n = 11) and those born prior to the pandemic (pre-Covid group, n = 22). Main Outcome Variable: Breastfeeding at hospital discharge. Results: Fewer infants in the Covid group received breastfeeds at full oral feed (p = .015) and none breastfeeding at hospital discharge (p = .001). In addition, fewer infants in the Covid group received non nutritive sucking (p = .612) and more infants in the Covid group required milk supplementation (p = .032). Study results suggest that breastfeeding establishment at hospital discharge in preterm infants is significantly impacted by the Covid-19 pandemic. There is a critical need, in low-risk disease transmission areas, to enhance parental access and to increase in-hospital lactation supports to help safeguard breastfeeding outcomes in preterm infants.

Breastfeeding in times of COVID-19: a scoping review

OBJECTIVE

to identify how the COVID-19 pandemic has influenced postpartum women in breastfeeding.

METHOD

a scoping review, with a search in seven databases. Studies available in full, in English, Portuguese or Spanish, published from December/2019-April/2021 were included. The analysis was carried out by categorizing common themes.

RESULTS

25 studies were included, grouped into five categories, presenting the influence of the pandemic: in the routine of breastfeeding care, evidencing preventive measures against COVID-19; in breastfeeding rates, highlighting changes in dietary practices; in the support network for breastfeeding, indicating a lack of service care; in the postpartum women's emotions, with predominance of concern and stress; in the use of technology to support breastfeeding, with teleservice facilitating care.

CONCLUSION

the COVID-19 pandemic has influenced new forms of care, in the offer and duration of breastfeeding, in emotional health and in the support network fragility. It is expected to contribute so that health professionals provide care with greater assertiveness in the face of this new situation.

Overview of Breastfeeding Under COVID-19 Pandemic

During the global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), pregnant and lactating women are at higher risk of infection. The potential of viral intrauterine transmission and vertical transmission by breastfeeding has raised wide concerns. Breastmilk is rich in nutrients that contribute to infant growth and development, and reduce the incidence rate of infant illness and death, as well as inhibit pathogens significantly, and protect infants from infection. Although it is controversial whether mothers infected with COVID-19 should continue to breastfeed, many countries and international organizations have provided recommendations and guidance for breastfeeding. This review presents the risks and benefits of breastfeeding for mothers infected with COVID-19, and the reasons for the absence of SARS-CoV-2 active virus in human milk. In addition, the antiviral mechanisms of nutrients in breastmilk, the levels of SARS-CoV-2 specific antibodies in breastmilk from COVID-19 infected mothers and vaccinated mothers are also summarized and discussed, aiming to provide some support and recommendations for both lactating mothers and infants to better deal with the COVID-19 pandemic.

Neonates and COVID-19: state of the art : Neonatal Sepsis series

The SARS-CoV-2 pandemic has had a significant impact worldwide, particularly in middle- and low-income countries. While this impact has been well-recognized in certain age groups, the effects, both direct and indirect, on the neonatal population remain largely unknown. There are placental changes associated, though the contributions to maternal and fetal illness have not been fully determined. The rate of premature delivery has increased and SARS-CoV-2 infection is proportionately higher in premature neonates, which appears to be related to premature delivery for maternal reasons rather than an increase in spontaneous preterm labor. There is much room for expansion, including long-term data on outcomes for affected babies. Though uncommon, there has been evidence of adverse events in neonates, including Multisystem Inflammatory Syndrome in Children, associated with COVID-19 (MIS-C). There are recommendations for reduction of viral transmission to neonates, though more research is required to determine the role of passive immunization of the fetus via maternal vaccination. There is now considerable evidence suggesting that the severe visitation restrictions implemented early in the pandemic have negatively impacted the care of the neonate and the experiences of both parents and healthcare professionals alike. Ongoing collaboration is required to determine the full impact, and guidelines for future management. IMPACT: Comprehensive review of current available evidence related to impact of the COVID-19 pandemic on neonates, effects on their health, impact on their quality of care and indirect influences on their clinical course, including comparisons with other age groups. Reference to current evidence for maternal experience of infection and how it impacts the fetus and then neonate. Outline of the need for ongoing research, including specific areas in which there are significant gaps in knowledge.

Objectives

To provide evidence-based guidelines to help the healthcare professionals to advise optimal breastfeeding practices during the COVID-19 pandemic.

Process

Formulation of key questions was done under the chairmanship of President of the IAP. It was followed by review of literature and the recommendations of other international and national professional bodies. Through Infant and Young child (IYCF) focused WhatsApp group opinion of all members was taken. The final document was prepared after the consensus and approval by all members of the committee.

Recommendations

The IYCF Chapter of IAP strongly recommends unabated promotion, protection and support to breastfeeding during the COVID-19 pandemic with due precautions.

Delivery management of suspected or confirmed COVID-19 positive mothers

The Coronavirus Disease-2019 (COVID-19) pandemic has brought catastrophic impact on the world since the beginning of December 2019. Extra precautionary measures against COVID-19 during and after delivery are pivotal to ensure the safety of the baby and health care workers. Based on current literature, it is recommended that delivery decisions be discussed between obstetricians and neonatologists prior to delivery, and designated negative pressure delivery rooms should be arranged for COVID person under investigation (PUI). During delivery, a minimal number of experienced staff attending delivery should don personal protective equipment (PPE) and follow the neonatal resuscitation program (NRP). Positive pressure ventilation is best used in a negative pressure room if available. At-risk babies should be transported in an isolette, and tested for COVID-19 in a negative pressure room soon after bathing. Skin-to-skin contact and breast milk feed should continue under certain circumstances. Although newborns with COVID-19 infections often present with symptoms that mimic sepsis and one third of affected patients may demand some form of respiratory support, short-term prognoses are favorable and most recover within two weeks of symptoms onset. In this article, we will further elaborate on topics covering timing and mode of delivery, antenatal steroid, vertical transmission, delivery room management, airway management, transport, testing and isolation after birth, skin-to-skin contact, breast milk feeding, clinical features, outcomes, and discharge plans. In addition, we also share our experiences of encountering neonates born of suspected COVID-19 positive mothers.

Natural resources to control COVID-19: could lactoferrin amend SARS-CoV-2 infectivity?

The world population is still facing the second wave of the COVID-19 pandemic. Such a challenge requires complicated tools to control, namely vaccines, effective cures, and complementary agents. Here we present one candidate for the role of an effective cure and/or complementary agent: lactoferrin. It is the cross-talking mediator between many organs/cellular systems in the body. It serves as a physiological, immunological, and anti-microbial barrier, and acts as a regulator molecule. Furthermore, lactoferrin has receptors on most tissues cells, and is a rich source for bioactive peptides, particularly in the digestive system. In the past months, in vitro and in vivo evidence has accumulated regarding lactoferrin's ability to control SARS-CoV-2 infectivity in different indicated scenarios. Also, lactoferrin or whey milk (of human or other mammal's origin) is a cheap, easily available, and safe agent, the use of which can produce promising results. Pharmaceutical and/or food supplementary formulas of lactoferrin could be particularly effective in controlling the gastrointestinal COVID-19-associated symptoms and could limit the fecal-oral viral infection transmission, through mechanisms that mimic that of norovirus infection control by lactoferrin via induction of intestinal innate immunity. This natural avenue may be effective not only in symptomatic patients, but could also be more helpful in asymptomatic patients as a main or adjuvant treatment.
