Abstract Objective To analyze the factors associated with restricting the follow-up of infants who were born premature and/or low birth weight during the COVID-19 pandemic and mothers' and health professionals' perception regarding this reality. Methods This is mixed methods research with a parallel convergent design, carried out with 14 mothers of infants who were born premature and/or low birth weight, followed up at a follow-up outpatient clinic of a maternity hospital in a municipality in Paraíba, and four health professionals from this service. Data collection was carried out from June to July 2020, concomitantly, in a secondary data source, consisting of all 140 medical records of the respective infants for a quantitative approach, through a semi-structured interview, for a qualitative approach. Quantitative analysis was performed using descriptive and inferential statistics, and qualitative analysis, according to inductive thematic analysis. Results There was a significant association between infant age and the restriction of their follow-up during the pandemic, with prioritization of one-to-one care for children under six months of age, occasional contacts with family members, via phone call or digital application, and gaps in updating the vaccination schedule of those whose follow-up was interrupted. This generated dissatisfaction on the part of mothers and fear of harm to the development of infants. There was also no continuity of care for these in the Basic Health Unit. Conclusion There were restrictions on follow-up of premature infants in the follow-up service during the pandemic, generating maternal dissatisfaction and fear of damage to the development of their children.

COVID-19 vaccine hesitancy among women planning for pregnancy, pregnant or breastfeeding mothers in Jordan: A cross-sectional study.

BACKGROUND: Women planning to become pregnant, who are pregnant, and who are breastfeeding are more hesitant to take COVID-19 vaccines compared to other women globally. AIM: This study investigates COVID-19 vaccine hesitancy among women, who are planning for pregnancy, currently pregnant, and breastfeeding women in Jordan. METHODS: An online cross-sectional study was conducted in the biggest three cities in Jordan, including 874 women. RESULTS: Women who were planning for pregnancy, pregnant, or breastfeeding reported statistically significant lower levels of perception of the seriousness of COVID-19 (7.12 ± 0.72, 7.53 ± 1.80, 7.2439 ± 7296, respectively), significant lower levels of perceived benefits of the vaccine (8.92 ± 2.15, 8.73 ± 1.93, 9.09 ± 2.10, respectively), significant lower levels of motivation and causes of action (7.15 ± 1.71, 6.7524 ± 1.40, 7.27 ± 1.68, respectively), and significantly higher levels of COVID-19 vaccination hesitancy (31.32 ± 6.40, 30.11 ± 4.49, 30.27 ± 6.29, respectively) than other women. Married women, those whoe were previously infected with COVID-19, and those who had chronic diseases reported statistically significant lower levels of perception of COVID-19 seriousness, perceived benefits of COVID-19 vaccine, motivation to take COVID-19 vaccine, and causes of action, and significantly higher levels of hesitancy to take COVID-19 vaccine than unmarried women, those who have not been infected with COVID-19, and those who were medically healthy (p<0.001). There were statistically significant positive correlations between perception, perceived benefits, motivation, and cause of action with years of education; and statistically significant negative correlations between perception, perceived benefits, motivation, and cause of action with age (p<0.001). CONCLUSIONS: Women who were planning for pregnancy, pregnant, or breastfeeding in Jordan showed miderate scores in COVID-19 vaccine hesitancy despite the current international recommendations for its safety for women and their foetuses or neonates.

Understanding COVID-19 vaccination decisions during pregnancy and while breastfeeding in a Canadian province.

BACKGROUND: Vaccination in pregnancy is important for preventing illness for mothers and babies; however, vaccine uptake in pregnant individuals is lower than non-pregnant females of fertile age. Given the devastating effects of COVID-19 and the increased morbidity and mortality risk for pregnant individuals, it is important to understand the determinants of vaccine hesitancy in pregnancy. The focus of our study was to explore COVID-19 vaccination among pregnant and breastfeeding individuals and its association with their reasons (psychological factors) for vaccination using the 5C scale and other factors. METHODS: An online survey investigating prior vaccinations, level of trust in healthcare providers, demographic information, and the 5C scale was used for, pregnant and breastfeeding individuals in a Canadian province. RESULTS: Prior vaccinations, higher levels of trust in medical professionals, education, confidence, and collective responsibility predicted increased vaccine uptake pregnant and breastfeeding individuals. CONCLUSIONS: There are specific psychological and socio-demographic determinants that affect COVID-19 vaccine uptake in pregnant populations. Implications of these findings include targeting these determinants when informing and developing intervention and educational programs for both pregnant and breastfeeding individuals, as well as healthcare professionals who are making vaccine recommendations to patients. Study limitations include a small sample and lack of ethnic and socioeconomic diversity.

Folic acid - importance for human health and its role in COVID-19 therapy.

Folic acid (folacin, B9) is a vitamin that performs many very important functions in the human body, and its inadequate level - deficiency as well as excess, may contribute to an increased risk of developing many disease processes. The aim of this study was to analyze the available scientific literature on folic acid and its impact on human health. A systematic review of the studies, published until November 2022, was made on the basis of searching bibliographic databases such as: PubMed, Elsevier and Google Scholar. The following keywords and combinations were used: folic acid, folate, folic acid supplementation, folate deficiency. Folic acid, thanks to its high biological activity, has a direct and indirect effect on the metabolism of the human body cells. It plays a very important role, among others in the prevention of neural tube defects and megaloblastic anemia, the proper functioning of the nervous system, as well as reducing the risk of developing certain cancers. Currently, the important role of folic acid in maintaining the proper functioning of the immune system is also emphasized, which is of particular importance both in the prevention and in the situation of SARS-CoV-2 (COVID-19) infection. The effects of deficiency and excess of vitamin B9 may turn out to be dangerous to health and even life. There is a need for nutritional and health education of the society regarding the importance of folic acid for human health, due to the presence of large deficiencies in the population, which is particularly important for some social groups, such as, for example, women of procreation age, pregnant or breastfeeding, people with a nutrient malabsorption, and people who smoke or abuse alcohol.

Factors associated with exclusive breastfeeding in Israel during the COVID-19 pandemic: a subset of the IMAgiNE EURO cross-sectional study.

BACKGROUND: Evidence has shown that restrictions during the COVID-19 pandemic have negatively affected breastfeeding support and outcomes in hospitals in many countries. The aims of the study were to describe exclusive breastfeeding rates and identify factors associated with exclusive breastfeeding at hospital discharge among women who gave birth during the COVID-19 pandemic in Israel. METHODS: A cross-sectional online anonymous survey based on WHO standards for improving quality of maternal and newborn care in health facilities was conducted among a sample of women who gave birth to a healthy singleton infant in Israel during the pandemic (between March 2020 and April 2022). The socio-ecological approach was employed to examine intrapersonal, interpersonal, organizational, and community/society factors associated with exclusive breastfeeding at hospital discharge according to women perspectives. RESULTS: Among the 235 Israeli participants, 68.1% exclusively breastfed, 27.7% partially breastfed, and 4.2% did not breastfeed at discharge. Results of the adjusted logistic regression model showed that factors significantly associated with exclusive breastfeeding were the intrapersonal factor of multiparity (adjusted OR 2.09; 95% Confidence Interval 1.01,4.35) and the organizational factors of early breastfeeding in the first hour (aOR 2.17; 95% CI 1.06,4.45), and rooming-in (aOR 2.68; 95% CI 1.41,5.07). CONCLUSIONS: Facilitating early breastfeeding initiation and supporting rooming-in are critical to promoting exclusive breastfeeding. These factors, reflecting hospital policies and practices, along with parity, are significantly associated with breastfeeding outcomes and highlight the influential role of the maternity environment during the COVID-19 pandemic. Maternity care in hospitals should follow evidence-based breastfeeding recommendations also during the pandemic, promoting early exclusive breastfeeding and rooming-in among all women, with particular attention to providing lactation support to primiparous women.

The contributions of parental lactation on offspring development: It's not udder nonsense!

The Developmental Origins of Health and Disease (DOHaD) hypothesis describes how maternal stress exposures experienced during critical periods of perinatal life are linked to altered developmental trajectories in offspring. Perinatal stress also induces changes in lactogenesis, milk volume, maternal care, and the nutritive and non-nutritive components of milk, affecting short and long-term developmental outcomes in offspring. For instance, selective early life stressors shape the contents of milk, including macro/micronutrients, immune components, microbiota, enzymes, hormones, milk-derived extracellular vesicles, and milk microRNAs. In this review, we highlight the contributions of parental lactation to offspring development by examining changes in the composition of breast milk in response to three well-characterized maternal stressors: nutritive stress, immune stress, and psychological stress. We discuss recent findings in human, animal, and in vitro models, their clinical relevance, study limitations, and potential therapeutic significance to improving human health and infant survival. We also discuss the benefits of enrichment methods and support tools that can be used to improve milk quality and volume as well as related developmental outcomes in offspring. Lastly, we use evidence-based primary literature to convey that even though select maternal stressors may modulate lactation biology (by influencing milk composition) depending on the severity and length of exposure, exclusive and/or prolonged milk feeding may attenuate the negative in utero effects of early life stressors and promote healthy developmental trajectories. Overall, scientific evidence supports lactation to be protective against nutritive and immune stressors, but the benefits of lactation in response to psychological stressors need further investigation.

The Pent-Up Demand for Breastfeeding Among US Women: Trends After COVID-19 Shelter-in-Place.

Objectives. To estimate changes in national breastfeeding trends immediately before and after COVID-19‒related workplace closures in early 2020. Methods. The implementation of shelter-in-place policies in early 2020, when 90% of people in the United States were urged to remain at home, represents a unique natural experiment to assess the pent-up demand for breastfeeding among US women that may be stymied by the lack of a national paid leave policy. We used the 2017-2020 Pregnancy Risk Assessment Monitoring System (n = 118 139) to estimate changes in breastfeeding practices for births occurring before and after shelter-in-place policies were implemented in the United States. We did this in the overall sample and by racial/ethnic and income subgroups. Results. There was no change in breastfeeding initiation and a 17.5% increase in breastfeeding duration after shelter-in-place, with lingering effects through late 2020. High-income and White women demonstrated the largest gains. Conclusions. The United States ranks worse than similar countries when it comes to breastfeeding initiation and duration. This study suggests that this is partly attributable to inadequate access to postpartum paid leave. This study also demonstrates inequities introduced by patterns of remote work during the pandemic.

Women's suggestions on how to improve the quality of maternal and newborn care during the COVID-19 pandemic in Italy: A co-occurrence network analysis.

Background: Recent evidence revealed significant gaps in the quality of maternal and newborn care in the World Health Organization (WHO) European Region (EUR) countries. Collecting and analyzing women's views on their needs and priorities is crucial for developing actions to improve the quality of maternal and newborn care. With this study from the IMAgiNE EURO Project, we aimed to add to previous quantitative studies by analysing emerging themes from women's suggestions on how to improve the quality of maternal and newborn care during facility-based birth in Italy during the COVID-19 pandemic. Methods: We collected data from mothers giving birth during the coronavirus 2019 (COVID-19) pandemic using a validated online anonymous WHO standard-based questionnaire consisting of open-ended questions. Using a word co-occurrence network (WCON), we analysed responses in Italian from women who gave birth between March 2020 and March 2022. This approach entails a graphical representation of word pairings that frequently co-occur across sentences and compose clusters. Results: The texts, produced by 2010 women participating in the study, consisted of 79 204 words and 3833 sentences. Eight clusters emerged with WCON, the three largest of which were related to companionship during childbirth, breastfeeding support, and physical resources. The term "swab", associated with other terms in the COVID-19 domain, had the highest degree of centrality, thus representing a core topic. Conclusions: The key emerging themes from women's suggestions can be used to shape policies to improve the quality of care for mothers and newborns. Our WCON analysis offers a valid approach to quickly screen large textual data on quality of care, providing a first set of major themes identified by clusters. As such, it could be used to improve documentation of service users' suggestions promoting the engagement of both researchers and policymakers. Registration: ClinicalTrials.gov: NCT04847336.

Factors associated with exclusive breastfeeding at discharge during the COVID-19 pandemic in 17 WHO European Region countries.

BACKGROUND: Exclusive breastfeeding is the optimal infant nutrition, providing infants immunoprotection against many diseases including SARS-CoV-2 infection. Restrictions during the COVID-19 pandemic may have negatively affected breastfeeding practices in maternity care facilities. The aims of the study were to examine exclusive breastfeeding rates at discharge over time and to identify factors associated with exclusive breastfeeding during the pandemic. METHODS: A cross-sectional survey was conducted among mothers who gave birth in a maternity care facility in the World Health Organization (WHO) European Region countries during the COVID-19 pandemic. The socio-ecological model was employed to examine intrapersonal, interpersonal, organizational, and community/society factors associated with maternal report of exclusive breastfeeding at the time of discharge. RESULTS: There were 26,709 participating mothers from 17 European Region countries who were included in the analysis. Among the mothers, 72.4% (n = 19,350) exclusively breastfed and 27.6% (n = 7,359) did not exclusively breastfeed at discharge. There was an overall decline in exclusive breastfeeding rates over time (p = 0.015) with a significantly lower rate following the publication of the WHO breastfeeding guidelines on 23 June 2020 (AOR 0.88; 95% CI 0.82, 0.94). Factors significantly associated with exclusive breastfeeding outcomes in the logistic regression analysis included maternal age, parity, education, health insurance, mode of birth, inadequate breastfeeding support, lack of early breastfeeding initiation, lack of full rooming-in, birth attendant, perceived healthcare professionalism and attention, facility room cleanliness, timing of birth, and location of birth. CONCLUSIONS: Results from the study indicate the decline in exclusive breastfeeding rates in the WHO European Region during the COVID-19 pandemic. Using the socio-ecological model to identify factors associated with breastfeeding outcomes facilitates an integrated and holistic approach to address breastfeeding needs among women across the region. These findings demonstrate the need to augment breastfeeding support and to protect exclusive breastfeeding among mother-infant dyads, in an effort to reverse the declining exclusive breastfeeding rates. The study highlights the need to educate mothers and their families about the importance of exclusive breastfeeding, reduce maternal-infant separation, increase professional breastfeeding support, and follow evidence-based practice guidelines to promote breastfeeding in a comprehensive and multi-level manner. TRIAL REGISTRATION NUMBER: Clinical Trials NCT04847336.

The role of doulas in providing breastfeeding support during the COVID-19 pandemic.

BACKGROUND: Doulas have been instrumental in providing breastfeeding support to nursing mothers before and during the COVID-19 pandemic, as they can significantly impact a mother's ability to initiate and maintain breastfeeding. However, the COVID-19 pandemic, subsequent lockdowns, and social isolation created challenges for nursing mothers to access doulas' services, usually provided in person. In this study, we examined the role of doulas in providing breastfeeding support during the COVID-19 pandemic, exploring adaptation to COVID-19 guidelines and the challenges doulas face in providing breastfeeding support during the pandemic. METHODS: A systematic review was conducted following the PRISMA guidelines. Thirteen scientific databases and twenty peer-reviewed journals were searched for journal articles published in English between January 2020 and March 2022 using key search terms (e.g., Doula, Breastfeeding, COVID-19). Studies evaluating the role of doulas in providing breastfeeding support during COVID-19, and the impact of COVID-19 Guidelines on doula services, were included. Two reviewers independently performed the risk of bias assessment and data extraction. Summative content analysis was used to analyze the data. RESULTS: The majority of studies were conducted in developed nations. This systematic review includes eight articles, four qualitative, one survey, two mixed-methods studies, and one prospective research study. Seven of the eight studies were conducted in the United States, and the eighth was conducted in multiple countries. These studies have three main themes: (1) virtual breastfeeding support provided by doulas during the pandemic; (2) remote social support provided by doulas to breastfeeding mothers during the pandemic; and (3) barriers to doula service delivery due to COVID-19 restrictions, primarily the exclusion of doulas as essential workers. The eight studies showed that doulas found innovative ways to serve the needs of birthing and nursing mothers during the difficulties brought on by the pandemic. CONCLUSION: Doulas provided breastfeeding support during the COVID-19 pandemic by utilizing innovative service delivery methods while navigating changes in COVID-19 guidance. However, system-level integration of doulas' work and the acknowledgment of doulas as essential healthcare providers are needed to enhance doula service delivery capacity, especially during a pandemic, to help improve maternal health outcomes.

Maternal emotional regulation strategy is associated with newborn feeding practices within 72 h after delivery: Cross sectional analyses of a multi-center study in China.

BACKGROUND: Early feeding practices have a great impact on the growth and development of infants, and the health of mothers. Maternal emotional regulation (ER) is closely related to infant feeding practices. Exploring the relationship between ER strategy and feeding practice can inform early exclusive breastfeeding (EBF) interventions. METHODS: Using baseline survey of a longitudinal study, 965 mothers in Chongqing municipality, Guangzhou city, and Huizhou city were enrolled. At baseline, the study used self-administrated questionnaires to investigate the socio-demographic characteristics, maternal ER strategies and feeding practice within 72 h of delivery. Chi-square test and logistic regression were used to determine the associations of the mothers' ER and feeding practices within 72 h postpartum. RESULTS: Among 965 participants, 27.8 % of mothers practiced EBF, and 69.5 % of mothers reported getting breastfeeding education from health providers. The average scores on the cognitive reappraisal and the expressive suppression of the ERQ were 29.95 ± 7.24 and 14.47 ± 5.16 respectively. Multivariable analysis showed women with expressive suppression were less likely to practice EBF (aOR = 0.96, 95%CI: 0.93-0.98, p = 0.002), while receiving breastfeeding education was positively associated with EBF (aOR = 1.52, 95%CI: 1.09-2.12, p = 0.013). LIMITATIONS: Because the study started during the COVID-19 pandemic, the lock-down measures paused recruitments for quite some time reducing the enrollment of participation. The data we used was within 72 h postpartum, hence the period of time to study feeding practices was short. CONCLUSION: Mothers' ER strategy and breastfeeding education need to be addressed as part of interventions designed to improve EBF rates during the newborn period in China.

Improving breastfeeding support through the implementation of the Baby-Friendly Hospital and Community Initiatives: a scoping review.

BACKGROUND: Improved breastfeeding practices have the potential to save the lives of over 823,000 children under 5 years old globally every year. The Baby-Friendly Hospital Initiative (BFHI) is a global campaign by the World Health Organization and the United Nations Children's Fund, which promotes best practice to support breastfeeding in maternity services. The Baby-Friendly Community Initiative (BFCI) grew out of step 10, with a focus on community-based implementation. The aim of this scoping review is to map and examine the evidence relating to the implementation of BFHI and BFCI globally. METHODS: This scoping review was conducted according to the Joanna Briggs Institute methodology for scoping reviews. Inclusion criteria followed the Population, Concepts, Contexts approach. All articles were screened by two reviewers, using Covidence software. Data were charted according to: country, study design, setting, study population, BFHI steps, study aim and objectives, description of intervention, summary of results, barriers and enablers to implementation, evidence gaps, and recommendations. Qualitative and quantitative descriptive analyses were undertaken. RESULTS: A total of 278 articles were included in the review. Patterns identified were: i) national policy and health systems: effective and visible national leadership is needed, demonstrated with legislation, funding and policy; ii) hospital policy is crucial, especially in becoming breastfeeding friendly and neonatal care settings iii) implementation of specific steps; iv) the BFCI is implemented in only a few countries and government resources are needed to scale it; v) health worker breastfeeding knowledge and training needs strengthening to ensure long term changes in practice; vi) educational programmes for pregnant and postpartum women are essential for sustained exclusive breastfeeding. Evidence gaps include study design issues and need to improve the quality of breastfeeding data and to perform prevalence and longitudinal studies. CONCLUSION: At a national level, political support for BFHI implementation supports expansion of Baby-Friendly Hospitals. Ongoing quality assurance is essential, as is systematic (re)assessment of BFHI designated hospitals. Baby Friendly Hospitals should provide breastfeeding support that favours long-term healthcare relationships across the perinatal period. These results can help to support and further enable the effective implementation of BFHI and BFCI globally.

Assessment of the scope, completeness, and consistency of various drug information resources related to COVID-19 medications in pregnancy and lactation.

BACKGROUND: Drug use in pregnancy and lactation is challenging. It becomes more challenging in pregnant and lactating women with certain critical clinical conditions such as COVID-19, because of inconsistent drug safety data. Therefore, we aimed to evaluate the various drug information resources for the scope, completeness, and consistency of the information related to COVID-19 medications in pregnancy and lactation. METHODS: Data related to COVID-19 medications from various drug information resources such as text references, subscription databases, and free online tools were used for the comparison. The congregated data were analyzed for scope, completeness, and consistency. RESULTS: Scope scores were highest for Portable Electronic Physician Information Database (PEPID), Up-to-date, and drugs.com compared to other resources. The overall completeness scores were higher for Micromedex and drugs.com (p < 0.05 compared to all other resources). The inter-reliability analysis for overall components by Fleiss kappa among all the resources was found to be 'slight' (k < 0.20, p < 0.0001). The information related to the older drugs in most of the resources, provides in-depth details on various components such as pregnancy safety, clinical data related to lactation, the effect of the drug distribution into breast milk, reproductive potential/infertility risk and the pregnancy category/recommendations. However, the information related to these components for newer drugs was superficial and incomplete, with insufficient data and inconclusive evidence, which is a statistically significant observation. The strength of observer agreement for the various COVID-19 medications ranged from poor to fair and moderate for the various recommendation categories studied. CONCLUSION: This study reports discrepancies in the information related to pregnancy, lactation, drug level, reproductive risk, and pregnancy recommendations among the resources directing to refer to more than one resource for information about the safe and quality use of medications in this special population.The present study also emphasizes the need for development of comprehensive, evidence-based, and precise information guide that can promote safe and effective drug use in this special population.

Anti-SARS-CoV-2 Immunoglobulins in Human Milk after Coronavirus Disease or Vaccination-Time Frame and Duration of Detection in Human Milk and Factors That Affect Their Titers: A Systematic Review.

Human milk (HM) of mothers infected with or vaccinated against SARS-CoV-2 contains specific immunoglobulins, which may protect their offspring against infection or severe disease. The time frame and duration after infection or vaccination, during which these immunoglobulins are detected in HM, as well as the major factors that influence their levels, have not been fully elucidated. This systematic review aimed to collect the existing literature and describe the immune response, specifically regarding the immunoglobulins in HM after COVID-19 disease or vaccination in non-immune women. We conducted a systematic search of PubMed and Scopus databases to identify studies published up until 19 March 2023. In total, 975 articles were screened, and out of which 75 were identified as being relevant and were finally included in this review. Infection by SARS-CoV-2 virus primarily induces an IgA immune response in HM, while vaccination predominantly elevates IgG levels. These immunoglobulins give HM a neutralizing capacity against SARS-CoV-2, highlighting the importance of breastfeeding during the pandemic. The mode of immune acquisition (infection or vaccination) and immunoglobulin levels in maternal serum are factors that seem to influence immunoglobulin levels in HM. Further studies are required to determine the impact of other factors, such as infection severity, lactation period, parity, maternal age and BMI on immunoglobulin level in HM.
