RESUMO

BACKGROUND: Promoting exclusive breastfeeding can have a great effect in reducing the complications and mortality rate of mother and child. OBJECTIVE: The study aimed to compare the effects of continuous and intermittent supportive counselling on the self-efficacy and continuity of breastfeeding among Lactating mothers with COVID-19. METHODS: The study was a semi-experimental research method and was conducted on 73 mothers with COVID-19 who were hospitalized in Ayatollah Mousavi Hospital in Zanjan, Iran from May 2021 to April 2022. In the continuous counselling group, counselling was provided daily for 14 days, while in the intermittent counselling group, counselling was provided once a week for four weeks. Breastfeeding continuity was assessed based on the World Health Organization's classification, and breastfeeding self-efficacy was measured using Dennis' standard breastfeeding self-efficacy questionnaire (BSE) up to four months after delivery. The data were analyzed using chi-square tests, independent t-tests, paired t-tests, analysis of variance with repeated measures, and survival analysis (Kaplan-Meier) with a 95% confidence level. RESULTS: The survival analysis revealed that the cessation of exclusive breastfeeding occurred in 17 cases within the continuous counselling group and in 22 cases within the intermittent counselling group. The rates of continuation for exclusive breastfeeding were 52.8% and 40.5% in the continuous and intermittent counselling group respectively. However, no statistically significant differences were observed in the continuation of breastfeeding and the trend of changes in the mean scores of breastfeeding self-efficacies between the continuous and intermittent counselling groups. Furthermore, comparing the change in breastfeeding self-efficacy scores between the one-month and four-month follow-ups within the continuous counselling group, a statistically significant increase was observed. CONCLUSION: The results indicated no difference in the effectiveness of continuous and intermittent counseling methods in improving breastfeeding continuity in women with COVID-19. Further research is needed to explore the long-term effects of different counseling approaches on breastfeeding outcomes during crises. TRIAL REGISTRATION: The study was registered on the Iranian Registry of Clinical Trials website on 29/06/2021 with the registration code IRCT20150731023423N19.

RESUMO

BACKGROUND: Dysphoric Milk Ejection Reflex is an understudied condition of lactation involving emotional dysregulation during letdown or milk ejection. Affected individuals may experience transient feelings of helplessness, melancholy, and general unhappiness. RESEARCH AIM: To evaluate the scope of published literature on Dysphoric Milk Ejection Reflex. METHOD: Whittemore and Knafl's methodology guided this integrative review. Five databases were searched for primary research, summaries, and editorials on Dysphoric Milk Ejection Reflex in lactating individuals. Literature searched also included websites, pamphlets, and conference proceedings via Google and Google Scholar. A total of 11 articles, from five different countries, met inclusion criteria for review. RESULTS: Studies on Dysphoric Milk Ejection Reflex and negative emotional sensations during lactation were synthesized under five conceptual umbrellas: (1) Experiences, Sensations, and Symptom Management; (2) Biological Underpinnings; (3) Influence on Maternal Role and Breastfeeding Self-Efficacy; (4) Support, Understanding, and Awareness; and (5) Reduction and Cessation of Breastfeeding. CONCLUSION: Dysphoric Milk Ejection Reflex is a neurobiological condition characterized by low mood and negative feelings during milk ejection throughout lactation. Dysphoric Milk Ejection Reflex is linked to maternal psychological distress and breastfeeding discontinuation. Priority areas for future research include biological origins and interventions aimed at prevention, symptom control, and greater awareness of the condition on a more international scope.

RESUMO

PURPOSE: The purpose of this study is to examine perceptions and experiences of women who donate human milk and highlight various aspects of the breast milk donation process. STUDY DESIGN: A cross-sectional descriptive study. METHODS: An online survey was conducted with a convenience sample of women who donated milk at several milk banks in the United States. A questionnaire of 36 closed and open-ended items were developed and validated by the research team. Descriptive statistics and content analysis were used. Semantic content analysis involved three procedures: coding, categorizing text units, and refining the identified themes. RESULTS: A total of 236 women who donated breast milk completed the questionnaire. Mean age of participants was 32.7±4.27 and 89.40% were non-Hispanic White women with a bachelor's degree (32.20%) or graduate degree (54.70%). Most participants were women who actively donated breast milk, ranging from one to four times. Two themes, facilitators and barriers of milk donation, were identified. Facilitators to milk donation included attitudes toward milk donation, commitment for donating, motivation in donating, and support. Barriers included personal factors, environment, milk donor process, and psychosocial factors. CLINICAL IMPLICATIONS: Nurses, health care providers, and lactation professionals should educate women about milk donation resources and opportunities. Strategies to increase awareness about milk donation among underrepresented groups such as women of color are highly recommended. Future research is needed to further explore specific factors that increase milk donation awareness and minimize barriers to potential donors.

RESUMO

Karen Wambach recently retired from a distinguished career in nursing education and breastfeeding research in the United States, practicing her craft during the formative years of the field of lactation consulting. Her research focused on the description of biopsychosocial influences on breastfeeding initiation and duration, as well as interventions for promoting and supporting breastfeeding among vulnerable childbearing populations, for example, adolescent mothers. Her research career trajectory mirrors the development of breastfeeding research more broadly. She began with descriptive studies and theory testing, which included the development of the Breastfeeding Experience Scale quantifying early breastfeeding problems. She then moved on to randomized clinical trials of breastfeeding education/support for adolescent mothers, and finished her funded research using a multi-behavioral, technology-based education and support intervention to promote breastfeeding, healthy lifestyle, and depression prevention in adolescent mothers. As researcher and educator in a clinical science area, she has supported evidence-based practice and translational science through her work as lead editor of many editions of the textbook Breastfeeding and Human Lactation. She is a consummate teacher, having mentored many upcoming researchers during her teaching career, and directed the undergraduate nursing honors program and PhD program at the University of Kansas School of Nursing in the United States. She also believes in serving her profession and has been an active member of American Academy of Nursing, the Midwest Nursing Research Society, the Association of Women's Health, Obstetric, and the Neonatal Nursing and the International Lactation Consultant Association, including serving on JHL's Editorial Review Board for many years.

RESUMO

Dysphoric milk ejection reflect (D-MER) is a dysphoria which women may experience within seconds of commencing breastfeeding. It is only recently gaining recognition in the academic literature and may have important implications for breastfeeding continuation, differential diagnosis and perinatal mental health. This perspective piece introduces the topic, sets out the physiological processes underpinning the experience and outlines why increased awareness of D-MER is important for the profession of mental health nursing.

RESUMO

Breast milk is a highly valued substance, immunologically and nutritionally, which also signifies maternal care and love for the infant. This intersection of biological and cultural qualities confers breast milk with complex meanings, which necessarily shape the experience of breastfeeding. Our research, investigating the experience of lactation after the loss of an infant, casts a novel light on these meanings. This article analyses the experience of 17 Australian bereaved mothers and 114 health professionals charged with their care. We find that while all the mothers found post-loss lactation emotionally painful, many also found redemptive meaning in their milk-production, as a bond with the lost child, as confirmation of their maternal competence and as a life giving substance that they could donate to other needy infants. These complex meanings and positive connotations were at odds with hospital cultures that regard post-loss lactation as valueless and best dealt with through medical suppression, despite the more complex insights of individual health-care professions.

RESUMO

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.

RESUMO

PURPOSE: Despite recommendations from the World Health Organization and the American Academy of Pediatrics to exclusively breastfeed infants for their first 6 months of life, 75% of women do not meet exclusive breastfeeding guidelines, and 60% do not meet their own breastfeeding goals. Numerous observational studies have linked maternal psychological distress (eg, perceived stress, anxiety, and depression) with nonoptimal breastfeeding outcomes, such as decreased proportion and duration of exclusive breastfeeding. The physiological mechanisms underlying these associations, however, remain unclear. METHODS: For this narrative review, we evaluated the evidence of relationships between maternal psychological distress and lactation and breastfeeding outcomes in pregnancy and post partum and the possible physiological mechanisms that facilitate these relationships. We searched PubMed using the following terms: stress, anxiety, depression, breastfeeding, and lactation. Additional search by hand was conducted to ensure a thorough review of the literature. FINDINGS: Among the studies examined, methods used to assess maternal psychological distress were not uniform, with some studies examining perceived distress via a variety of validated tools and others measuring biological measures of distress, such as cortisol. Evidence supports a role for psychological distress in multiple breastfeeding outcomes, including delayed secretory activation and decreased duration of exclusive breastfeeding. One physiological mechanism proposed to explain these relationships is that psychological distress may impair the release of oxytocin, a hormone that plays a critical role in milk ejection during lactation. Continued impairment of milk ejection may lead to decreased milk production because of incomplete emptying of the breast during each feed. Maternal distress may also yield elevated levels of serum cortisol and decreased insulin sensitivity, which are associated with decreased milk production. The relationship between psychological distress and breastfeeding is likely to be bidirectional, however, in that breastfeeding appears to reduce maternal distress, again possibly via effects on the pleasure or reward pathway and calming effects of oxytocin on the mother. This finding suggests that interventions to support lactation and breastfeeding goals in women who score high on measures of psychological distress would be beneficial for both maternal and infant well-being. IMPLICATIONS: Evidence to date suggests that maternal psychological distress may impair lactation and breastfeeding outcomes, but stronger study designs and rigorous assessment methods are needed. A better understanding of the physiological mechanisms leading to impaired lactation may assist in the development of early interventions for mothers experiencing distress. In addition, stress-reducing programs and policies should be investigated for their potential to improve breastfeeding outcomes.

RESUMO

In the mammary gland, how alveolar progenitor cells are recruited to fuel tissue growth with each estrus cycle and pregnancy remains poorly understood. Here, we identify a regulatory pathway that controls alveolar progenitor differentiation and lactation by governing Notch activation in mouse. Loss of Robo1 in the mammary gland epithelium activates Notch signaling, which expands the alveolar progenitor cell population at the expense of alveolar differentiation, resulting in compromised lactation. ROBO1 is expressed in both luminal and basal cells, but loss of Robo1 in basal cells results in the luminal differentiation defect. In the basal compartment, ROBO1 inhibits the expression of Notch ligand Jag1 by regulating ß-catenin (CTNNB1), which binds the Jag1 promoter. Together, our studies reveal how ROBO1/CTTNB1/JAG1 signaling in the basal compartment exerts paracrine control of Notch signaling in the luminal compartment to regulate alveolar differentiation during pregnancy.

RESUMO

There are numerous dietary recommendations during pregnancy. However, there are limited recommendations during the lactation period, a nutritionally vulnerable period for women. The Mediterranean Diet and adherence to the Healthy Food Pyramid (HFP) is considered as the standard for healthy eating. In this study, we investigated the differences in adherence to the HFP in pregnant, lactating, and non-pregnant/non-lactating (NPNL) women concerning sociodemographic factors. A sociodemographic and nutritional and lifestyle questionnaire (AP-Q) were used to assess adherence to the HFP, including lifestyle. The AP-Q score ranges from 0 to 10 meaning the higher the score, the greater the adherence to the HFP. Lactating women had the lowest AP-Q score (6.13 [5.31; 6.82]) compared to the pregnant (6.39 [5.56; 7.05]) and NPNL women (6.27 [5.43; 6.88]), while pregnant women had the highest scores. Maternal age was positively correlated with AP-Q score in pregnant (rho = 0.22; p-Value < 0.001) and lactating women (rho = 0.18; p-Value < 0.001), but not in NPNL women. Educational level and monthly income had a positive influence on the degree of adherence to the HFP. In conclusion, breastfeeding mothers of young age and low socioeconomic and educational level would be the target population to carry out nutritional interventions that improve their adherence to the HFP. The knowledge gained from this study can help to design recommendation guidelines and nutritional educational interventions for a given population.

RESUMO

Prenatal stress (PS) is a major risk factor for the development of emotional disorders in adulthood that may be mediated by an altered hypothalamic-pituitary-adrenal axis response to stress. Although the early onset of stress-related disorders is recognized as a major public health problem, to date, there are relatively few studies that have examined the incidence of early-life stressors in younger individuals. In this study, we assessed PS impact on the stress-coping response of juvenile offspring in behavioral tests and in the induced molecular changes in the hippocampus. Furthermore, we assessed if pregnancy stress could be driving changes in patterns of maternal behavior during early lactation. We found that PS modified stress-coping abilities of both sex offspring. In the hippocampus, PS increased the expression of bdnf-IV and crfr1 and induced sex difference changes on glucocorticoids and BDNF mRNA receptor levels. PS changed the hippocampal epigenetic landscape mainly in male offspring. Stress during pregnancy enhanced pup-directed behavior of stressed dams. Our study indicates that exposure to PS, in addition to enhanced maternal behavior, induces dynamic neurobehavioral variations at juvenile ages of the offspring that should be considered adaptive or maladaptive, depending on the characteristics of the confronting environment. Our present results highlight the importance to further explore risk factors that appear early in life that will be important to allow timely prevention strategies to later vulnerability to stress-related disorders.

RESUMO

The relationship between stress responses and lactation is bidirectional. Breastfeeding confers many benefits to maternal health, including attenuated hypothalamic-pituitary-adrenal axis responsiveness to stress. However, increased stress burden can impair lactation. The mechanisms that underlie these relationships are poorly understood. The present study aimed to compare breastfeeding habits, as well as subjective and objective measures of stress, in employed and non-employed lactating women and assess the relationships between these measures and prolactin (PRL), thyroid hormones (thyroid-stimulating hormone, triiodothyronine [T3] and thyroxine), vasopressin and cortisol levels. A dexamethasone suppression test was also administered to determine the sensitivity of the hypothalamic-pituitary-adrenal axis to negative-feedback. We report that lactating employed women had lower breastfeeding rates and lower PRL than lactating non-employed women. They also had a significantly higher stress burden, indicated by elevations in blood pressure and evening cortisol, relative to lactating non-employed women. In regression analyses that controlled for feeding modality and breastfeeding duration, we found these factors differentially affected PRL in the two groups and there were significant differences in PRL across groups that were not accounted for by these factors. A mediation regression analysis suggested that group differences in PRL were best explained by differences in T3 and income levels, rather than breastfeeding duration or other variables. Our data fit a speculative model in which elevated maternal stress increases cortisol, which suppresses T3, leading to decreased PRL. The decreases in PRL are associated with higher rates of bottlefeeding, which may further contribute to decreased PRL.

RESUMO

STUDY OBJECTIVE: To explore the social and environmental conditions in emergency departments that contribute to perceived barriers and supports for workplace lactation among individuals working in emergency medicine. METHODS: Constructivist grounded theory was used by our team to understand the social processes and behaviors associated with workplace lactation for health care professionals working in EDs. A total of 24 interviews of individuals in EDs with recent return-to-work experience after childbirth were performed. The interviews yielded 36 unique experiences (from 21 faculty, 12 trainees, and 3 nurses) because some participants had more than 1 child, in which case all lactation experiences were discussed. Interview transcriptions were coded and analyzed iteratively for the development of themes, per constructivist grounded theory. RESULTS: Using constant comparative inductive methods, we describe 3 pervasive themes as they relate to workplace lactation that emerged from the analysis of interview data: (1) emergency medicine culture, (2) workplace lactation policies, and (3) supports for workplace lactation. CONCLUSION: Although formalized workplace lactation policies and other identifiable supports for workplace lactation aid individuals desiring to lactate after returning to work in EDs, many individuals still experience cultural barriers to their desired lactation habits. Policies and individual support systems may continue to fall short of meeting the needs of lactating individuals in emergency medicine unless broader cultural change occurs. Our work offers initial recommendations for shifting the landscape of lactation practices in emergency medicine.

RESUMO

Galactagogues are foods, herbs or medications thought to support or increase breast milk supply. The use of galactagogues during lactation is becoming increasingly common despite limited evidence regarding effectiveness and safety, and no definitive recommendations for use in clinical practice. The aim of this study is to explore factors influencing women's decisions to use galactagogues during lactation. Twenty-two semi-structured interviews were conducted in October and November 2019 (over the telephone or in person) with participants located in most Australian states and territories, including metro and regional areas. Interviews were audio-recorded, transcribed verbatim and thematically analysed using NVivo. Analysis revealed that following a concern about breast milk supply, the decision to use galactagogues was influenced by three core and interrelated domains: access to and quality of breastfeeding support, maternal agency and determination to provide breast milk. Women revealed many problematic experiences with health care professionals that left them feeling dismissed and confused due to provision of inconsistent and insufficient information that was sometimes at odds with their desire to provide breast milk. In this instance, some women turned to galactagogues to regain agency. A range of broader dimensions influencing decision-making also emerged. These were separated into categories that emphasise distinctions relating to breast milk supply, which included: maternal emotional wellbeing, social norms and pressures, concerns about infant development, maternal physical health and lactation history, as well as those relating specifically to galactagogue use, including: desire for a guaranteed/urgent response, risk-risk trade-off, acceptance and trust, and accessibility and cost. In understanding the complexity of decision-making concerning these substances, we identify opportunities to improve breastfeeding counselling and support. We recommend that support be individually tailored to manage conflicting information, adopt communication styles that encourage trust and processes that enable shared decision-making to enhance or restore maternal agency. There is also considerable need to address evidence gaps regarding the effectiveness and safety of commonly used galactagogues, so that women can be appropriately counselled about potential benefits and harms.

RESUMO

BACKGROUND: The impact of COVID-19 pandemic on mental health of pregnant and lactating women is unclear. This study aimed to assess the impact of COVID-19 on psychological health, sexual function, and quality of life (QoL) in Iranian pregnant and lactating women and compare the results with non-pregnant/non-lactating women. METHOD: This comparative cross-sectional study was carried out on pregnant and lactating women, with non-pregnant/non-lactating women from May to Jun 2020. Patients were asked to complete three questionnaires: Hospital Anxiety and Depression Scale (HADS), Female Sexual Function Index (FSFI), and Short-Form Health Survey (SF-12). One-way ANOVA was used to reveal the statistical differences between the three groups. RESULT: The mean age of patients was 20.81 ± 5.92 years old. The mean (SD) score of HADS in pregnant, lactating and non-pregnant / non-lactating women were 12.11 (6.72), 11.98 (8.44) and 9.38 (6.2) respectively, and the results showed that the scores in pregnant, lactating women were higher than non-pregnant / non-lactating women (P < 0.001). Also the mean (SD) score of QOL and FSFI was 68.29 (9.47), 74.18 (12.65), 79.03 (10.48) and 22.71 (8.16), 22.72 (8.16), 26.19 (3.93) in three groups and the scores in pregnant, lactating women were lower than non-pregnant/non-lactating women (P < 0.001). CONCLUSION: The COVID-19 epidemic increases the risk of depression, anxiety, FSD, and lowers QoL in pregnant and lactating women, with the general population. This suggests the urgent need for psychological intervention in the maternal population during the epidemic.

RESUMO

Planned and unplanned pregnancies are occurring among transgender men. Although the literature highlights the fact that many transgender men retain their reproductive pelvic organs and desire pregnancy, there is a dearth of information on best practices and standards of care guiding perinatal care for this population. A literature review was conducted to explore the reproductive health needs of transgender men related to reproductive desires, contraception, family planning, fertility preservation, pregnancy, birth, and lactation. Findings show that pregnant and birthing transgender men are reporting feelings of invisibility, isolation, and loneliness in highly gendered perinatal care environments. A lack of gender-affirming perinatal environments and experienced providers is contributing to the avoidance of care by transgender men and further discrimination in an already marginalized population. More research attention is needed to understand the reproductive health needs of pregnant and birthing transgender men and to optimize the care they receive.

RESUMO

Reproduction induces changes within the brain to prepare for gestation and motherhood. However, the dynamic of these central changes and their relationships with the development of maternal behavior remain poorly understood. Here, we describe a longitudinal morphometric neuroimaging study in female mice between pre-gestation and weaning, using new magnetic resonance imaging (MRI) resources comprising a high-resolution brain template, its associated tissue priors (60-µm isotropic resolution) and a corresponding mouse brain atlas (1320 regions of interest). Using these tools, we observed transient hypertrophies not only within key regions controlling gestation and maternal behavior (medial preoptic area, bed nucleus of the stria terminalis), but also in the amygdala, caudate nucleus and hippocampus. Additionally, unlike females exhibiting lower levels of maternal care, highly maternal females developed transient hypertrophies in somatosensory, entorhinal and retrosplenial cortices among other regions. Therefore, coordinated and transient brain modifications associated with maternal performance occurred during gestation and lactation.

RESUMO

Prenatal and early postnatal periods are important for brain development and neural function. Neonatal insults such as hypoxia-ischemia (HI) causes prolonged neural and metabolic dysregulation, affecting central nervous system maturation. There is evidence that brain hypometabolism could increase the risk of adult-onset neurodegenerative diseases. However, the impact of non-pharmacologic strategies to attenuate HI-induced brain glucose dysfunction is still underexplored. This study investigated the long-term effects of early environmental enrichment in metabolic, cell, and functional responses after neonatal HI. Thereby, male Wistar rats were divided according to surgical procedure, sham, and HI (performed at postnatal day 3), and the allocation to standard (SC) or enriched condition (EC) during gestation and lactation periods. In-vivo cerebral metabolism was assessed by means of [18 F]-FDG micro-positron emission tomography, and cognitive, biochemical, and histological analyses were performed in adulthood. Our findings reveal that HI causes a reduction in glucose metabolism and glucose transporter levels as well as hyposynchronicity in metabolic brain networks. However, EC during prenatal or early postnatal period attenuated these metabolic disturbances. A positive correlation was observed between [18 F]-FDG values and volume ratios in adulthood, indicating that preserved tissue by EC is metabolically active. EC promotes better cognitive scores, as well as down-regulation of amyloid precursor protein in the parietal cortex and hippocampus of HI animals. Furthermore, growth-associated protein 43 was up-regulated in the cortex of EC animals. Altogether, results presented support that EC during gestation and lactation period can reduce HI-induced impairments that may contribute to functional decline and progressive late neurodegeneration.

RESUMO

Interventions in mHealth have had positive effects on establishing and maintaining breastfeeding, but we still do not know what content women consult when downloading a breastfeeding mobile application. We conducted an observational, descriptive, and retrospective study using the data recorded by LactApp in 2019. The most frequently consulted topics were those related to breastfeeding technique, infant sleep, human milk management and storage, breastfeeding myths, breastfeeding stages, complementary feeding, infant care, and returning to work. Our study results suggest that LactApp's support seems to develop with mothers' needs according to their infant's development stage. The first breastfeeding days include more physiological answers. Between 15 days and 3 months, mothers look for support in topics like breastfeeding crisis/complications and returning to work. At 3 months to 1 year, answers are related to complementary feeding and weaning. When the user's infant is 1 year of age, mothers seek support for weaning, weaning management, and tandem breastfeeding.
