Abstract
Despite advances across the globe in breastfeeding initiation rates, many families continue to report they are not meeting their breastfeeding goals. Concerns about milk supply, infant nutritional intake, and infant weight gain are among the most commonly cited reasons for early breastfeeding cessation. Nurses working with individuals during the perinatal period are uniquely positioned to educate families and offer evidence-based interventions to promote optimal milk supply, infant growth, and maternal mental and physical health. Such interventions include early and frequent skin-to-skin care, emptying of the breast, and professional lactation support. By implementing such evidence-based practices in the first hours after birth and connecting families to lactation support in the first 14 days, nurses can begin to help families achieve their breastfeeding goals.

Dietary Intake of Polyphenols Enhances Executive/Attentional Functioning and Memory with an Improvement of the Milk Lipid Profile of Postpartum Women from Argentina. J Intell 2022; 10:jintelligence10020033. [PMID: 35736005 PMCID: PMC9224741 DOI: 10.3390/jintelligence10020033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Revised: 05/28/2022] [Accepted: 05/28/2022] [Indexed: 02/04/2023] Open
Abstract
Puerperium may lead to memory and executive/attentional complaints that interfere with women’s daily life. This might be prevented by dietary compounds, such as neuroprotective polyphenols. Their bioactivity depends on their effects on lipid metabolism in different tissues, such as the brain, fat, and breast. Thus, a polyphenol-related cognitive improvement may be associated with changes of lipids in human milk, which are key for infant neurodevelopment. A cross-sectional study was conducted on 75 postpartum women from Córdoba (Argentina), involving several neuropsychological tests. Diet was registered to identify polyphenol intake and food pattern adherence, with sociodemographic and other psychological variables (insomnia, stress, subjective cognitive complaints) being also studied. Triacylglycerols, cholesterol, and their oxidative forms were analyzed as milk biomarkers. Multivariate statistical methods were applied. Results confirmed that women who consumed polyphenols presented better executive/attentional performance (i.e., higher correct responses, conceptual level responses, complete categories, verbal fluency; lower attentional interferences, and perseverative errors) and word retention with lower interference. Polyphenols were positively associated with milk lipids, which were higher in women with better cognition. Furthermore, they had lower oxidized triacylglycerols. In conclusion, polyphenolic intake during postpartum may improve executive/attentional functioning, memory, and milk lipid profile.

Abstract
BACKGROUND When mothers are confronted with milk supply problems, taking domperidone is regularly suggested. However, domperidone has been associated with sudden cardiac death and caution in prescribing is advised. In 2016, a multidisciplinary group of authors from a tertiary academic hospital (Erasmus MC) published a clinical protocol in a leading Dutch physicians' journal to support Dutch family physicians in prescribing domperidone to stimulate lactation. RESEARCH AIM To explore consumer and health care provider perspectives and experiences regarding the prescribing of domperidone for lactation insufficiency following publication of a national clinical protocol. METHODS A cross-sectional qualitative study was performed using semi-structured interviews (N = 40) based on a topic list covering the prescribing process. Participants were mothers (n = 18) who had been advised to try domperidone to boost their milk supply between November 2016 and May 2018, their International Board Certified Lactation Consultants (n = 9), and their family physicians (n = 15). Another group of participants (mothers; n = 6) answered short questionnaires. All interviews were recorded, transcribed and analyzed using ATLAS.ti software. The resulting list of codes was organized according to the topics. RESULTS In the process leading to domperidone use to stimulate lactation, participant family physicians relied on the IBCLC, pharmacist, or mother to guide the prescription of domperidone, often citing the published national clinical protocol as back up. The medical safeguards incorporated in the protocol (e.g., taking medical history, physical exam, performing electrocardiograms, limiting dosage) were usually not implemented. CONCLUSIONS Though the availability of a national clinical protocol in which the prescribing of domperidone for lactation is supported appeared to increase the willingness of participant family physicians to prescribe, gaps were identified between clinical practice and this clinical protocol for prescribing domperidone.

Abstract
Background: Gestational diabetes mellitus (GDM) may be associated with delayed onset of lactogenesis (DOL), but it is still inconclusive. Objectives: The study aimed to evaluate the association between GDM and DOL, the prevalence and risk factors of DOL in GDM women. Materials and Methods: A comprehensive search was performed in 10 electronic databases from inception to June 1, 2020. To find more eligible studies, the references of finally eligible studies and relevant reviews were traced manually. A meta-analysis was conducted to calculate the pooled estimates of association, prevalence, and risk factors using random- or fixed-effects models. Results: Eleven eligible articles involving 8,150 women were included in this study. GDM women had a higher risk of DOL (odds ratio [OR] = 1.84, 95% confidence interval [CI] [1.34-2.52]). The prevalence of delayed lactogenesis onset in GDM women was 35.0% (effect size [ES] = 0.35, 95% CI [0.30-0.40]). Primipara (OR = 2.54, 95% CI [1.89-3.42]), advanced age (OR = 1.05, 95% CI [1.03-1.08]), prepregnancy obesity (OR = 1.55, 95% CI [1.19-2.03]), and insulin treatment (OR = 3.07, 95% CI [1.71-5.47]) were risk factors of delayed lactogenesis onset in GDM women. Conclusion: GDM negatively affects the timing of lactogenesis onset. The prevalence of delayed lactogenesis onset in GDM women is 35.0%. Primipara, advanced age, prepregnancy obesity, and insulin treatment are independent risk factors of delayed lactogenesis onset in GDM women.

Abstract
BACKGROUND Low milk supply is frequently reported as a reason for exclusive breastfeeding cessation. RESEARCH AIMS To determine the occurrence of, and the risk factors associated with, delayed onset of lactogenesis II among primiparas seen at a Baby-Friendly Hospital in Brazil. METHOD We conducted a prospective longitudinal observational cohort study of 224 primiparas who had a singleton delivery. Data were first collected at the hospital. We assessed the onset of lactogenesis on day four postpartum, based on maternal reports of changes in breast fullness. Breastfeeding practices and Edinburgh Postnatal Depression Scale were evaluated on day seven postpartum. Using Poisson regression, we assessed significant factors associated with delayed onset of lactogenesis II. RESULTS Delayed lactogenesis II occurred in 18.8% (n = 42) of participants and was significantly associated with alcohol drinking during pregnancy (IRR = 2.710, 95% CI [1.469, 4.996]); Edinburgh Postnatal Depression Scale scores ≥ 10 (IRR = 2.092, 95% CI [1.118, 3.916]), and the age of the mother (IRR: 1.081, 95% CI [1.039, 1.125]). CONCLUSION Postpartum depression and alcohol ingestion during pregnancy may be associated with lactogenesis II delay, but more research is needed to elucidate the directionality of these relationships. Older mothers are at risk of delayed lactogenesis II onset. The frequency of delayed lactogenesis in this population is similar to the rates seen in previous Latin America studies and much lower than the ranges seen in North America, possibly because of the low proportion of obesity and severe gestational diabetes in this sample.

Abstract
While correlational studies suggest that lactation may confer a certain level of protection from mental illness, this benefit is not uniformly expressed in all women who choose to breastfeed. We propose here that the neuroendocrine "resetting" induced by lactation may predispose toward positive affect states in a subset of hormone-sensitive mothers, with hormone-gene and hormone-environment interactions determining the ultimate psychological outcome. We find evidence to suggest that higher secretion of prolactin/oxytocin as well as lower secretion of vasopression/androgens in lactating mothers may protect against postpartum depression and anxiety, decrease levels of irritability, and optimize stress responses. On the other hand, while the abrupt withdrawal of estradiol/progesterone in the immediate postpartum period tends to be associated with adverse psychological outcomes, the chronic suppression of estrogens/progestogens induced by lactation may have antidepressant and anxiolytic effects over time. Finally, the hypo-cortisolemic state seen in lactating mothers appears to be associated with improved stress reactivity and circadian rhythms. We also discuss hormone-gene and hormone-environment interactions likely to modulate any potential psychological benefits related to lactation and focus on those factors that are either easy to screen for or known to be modifiable. In sum, neuroendocrine alterations induced by lactation may play a key role in determining reproductive psychiatric risk in a subset of hormone-sensitive women. Using these neuroendocrine factors as an individualized index of risk can help in devising targeted programs to support these women in pursuing lactation or, for those not able or willing, accessing psychological interventions in a timely manner.

Abstract
BACKGROUND Several factors can influence the production of mothers' own milk. PURPOSE To assess the influence of maternal psychological stress, maternal cortisol levels, and neonatal hair cortisol levels on timing of secretory activation. METHODS A prospective study was conducted at 2 public health centers in Andalusia, Spain. Participants were 60 pregnant women and their 60 neonates. Hair cortisol levels and psychological stress (pregnancy-specific stress [Prenatal Distress Questionnaire, PDQ] and perceived stress [Perceived Stress Scale, PSS]) were evaluated during the third trimester and the postpartum period. This study was part of the GESTASTRESS cohort study on the effects of stress during pregnancy. RESULTS Higher PDQ and PSS scores (P < .05) in the third trimester were associated with later onset of secretory activation. Higher postpartum maternal hair cortisol levels were associated with a delayed secretory activation of mother's own milk (P < .05). IMPLICATIONS FOR RESEARCH Future studies should look at the influence of psychological stress and cortisol levels on hormones involved in mother's own milk production. IMPLICATIONS FOR PRACTICE Neonatal nurses and other healthcare providers should be familiar with levels of neonates' exposure to maternal prenatal stress prior to birth.

Abstract
BACKGROUND Metabolic and hormonal disturbances are associated with sleep disturbances and delayed onset of lactogenesis II. RESEARCH AIMS The aim of this study was to measure sleep using wrist actigraphy during gestation weeks 22 and 32 to determine if sleep characteristics were associated with blood glucose, body mass index, gestational related disease, delayed onset of lactogenesis II, or work schedule. METHODS Demographic data were collected at study intake from primiparous women who wore a wrist actigraph during gestation weeks 22 (n = 50) and 32 (n = 44). Start and end sleep time, total nighttime sleep, sleep efficiency, wake after sleep onset, and sleep fragmentation were measured. Night to night variability was assessed with the root mean square of successive difference. Blood glucose levels, body mass index, and gestational disease data were abstracted from medical charts. Timing of lactogenesis II was determined by survey. RESULTS Between gestation week 22 and 32, sleep efficiency decreased and fragmentation increased (p < .05). During gestation week 32, blood glucose was negatively correlated with sleep duration, and positively related to fragmentation (p < .05). Women who experienced delayed lactogenesis II had lower sleep efficiency and greater fragmentation (p < .05), and greater night-to-night variability in sleep start and end time, efficiency, and duration during gestation week 32 (p < .05). CONCLUSION Women with better sleep efficiency and more stable nightly sleep time are less likely to experience delayed onset of lactogenesis II. Interventions to improve sleep may improve maternal health and breastfeeding adequacy.

Abstract
PURPOSE This study aimed to evaluate the effect of delayed lactogenesis Ⅱ on early milk volume in mothers expressing milk for their preterm infants. METHODS 142 mothers with preterm infants participated in a longitudinal cohort study, the milk volumes over 14 days postpartum between mothers with delayed lactogenesis Ⅱ (≥ 72 hours) and mothers with non-delayed lactogenesis Ⅱ(< 72 hours) were compared using Wilcoxon's rank sum tests. RESULTS The prevalence of delayed lactogenesisⅡ among mothers of preterm infants was 36.0% (36/100). There existed negative correlations between the onset of lactogenesis Ⅱ and the daily milk volumes( rs = -0.525∼-0.354, p = .002 ∼ p < .001). The milk volumes in every 24-hour of the 14 days postpartum in delayed group were significantly less than that in non-delayed group (p = .002 ∼ p < .001). After controlling for the covariates, pregnancy-induced hypertension syndrome, delayed expression initiation, shorter daily sleeping time were found to be the risk factors for delayed lactogenesis Ⅱ. CONCLUSION Delayed lactogenesis Ⅱ was associated with lower milk volume in early postpartum period. Women who were at risk for delayed lactogenesis Ⅱ need targeted interventions and additional support during pregnancy and postpartum.

Abstract
BACKGROUND Breastfeeding (BF) neonates generally lose weight after birth. Neonatal factors like gestational age, birth weight and mode of delivery can affect the neonatal weight loss after birth. Similarly, maternal age, parity and illness may contribute to newborn weight loss. However, influence of the time of birth and season on changes in weight is not well elucidated. OBJECTIVE The aim of this study is to determine the effect of birth time and the seasonal variations on weight loss in BF newborns. METHODS In this retrospective study of a prospectively maintained database of two sets of groups, from January 2013 to October 2016, were evaluated- Birth time group and Seasonal group; Birth time of the groups was: night time 7pm to 7am and day time 7am to 7pm; and the seasonal variations groups studies were summer, fall, winter and spring. Weight loss of >5%, 7%, and 10% at <24 hours (h), 48 h and 72 h of birth, respectively, were considered as a significant weight loss. Preterm, exclusively formula fed and neonates admitted to NICU were excluded. RESULTS A total of 2044 newborns were analyzed. In the birth time group, babies born during the night time had significantly lost >5% of birth weight at <24 h (p < 0.01) and >7% birth weight at <48 h of life (p < 0.02). Weight loss >10% at <72 h was similar in both birth time cohorts. C-section, prolonged rupture of membrane, and maternal pre-delivery hospital stay for >12 h were significant contributing factors. Whereas, seasonal variations were not associated with weight loss in neonates. CONCLUSION BF babies born at night time lose significantly more weight during the first two days of life and seasonal association was not found to affect weight loss in the neonates.

Abstract
Sleep quality during pregnancy affects maternal/child health. We aimed to assess changes in sleep quality during pregnancy and determine its relationship to maternal mood, blood glucose, and work schedule among primiparous women. We conducted a prospective/longitudinal/observational study. Ninety-two pregnant women were recruited from Midwestern hospital. Mood and sleep quality data were collected using Edinburgh Postnatal Depression Scale/Pittsburgh Sleep Quality Index at Gestational Weeks 22 and 32. Forty-three women completed the study. Twenty-six women (63%) were African American and the mean age was 23.64 ( SD = 3.82) years. Rate of poor sleep quality increased during pregnancy with 25% of women had scores indicative of depression symptoms. Poor sleep quality score was related to mood scores ( p < .05) and work schedule. Blood glucose was not significantly related to sleep duration. In conclusion, poor sleep quality during pregnancy was associated with poor mood and work schedule, suggesting that interventions targeting mental health and lifestyles are needed.

Abstract
Objective This research aimed to determine biological pathways and protein-protein interaction (PPI) networks for 305-d milk yield (MY), 305-d fat yield (FY), and age at first calving (AFC) in the Thai multibreed dairy population. Methods Genotypic information contained 75,776 imputed and actual single nucleotide polymorphisms (SNP) from 2,661 animals. Single-step genomic best linear unbiased predictions were utilized to estimate SNP genetic variances for MY, FY, and AFC. Fixed effects included herd-year-season, breed regression and heterosis regression effects. Random effects were animal additive genetic and residual. Individual SNP explaining at least 0.001% of the genetic variance for each trait were used to identify nearby genes in the National Center for Biotechnology Information database. Pathway enrichment analysis was performed. The PPI of genes were identified and visualized of the PPI network. Results Identified genes were involved in 16 enriched pathways related to MY, FY, and AFC. Most genes had two or more connections with other genes in the PPI network. Genes associated with MY, FY, and AFC based on the biological pathways and PPI were primarily involved in cellular processes. The percent of the genetic variance explained by genes in enriched pathways (303) was 2.63% for MY, 2.59% for FY, and 2.49% for AFC. Genes in the PPI network (265) explained 2.28% of the genetic variance for MY, 2.26% for FY, and 2.12% for AFC. Conclusion These sets of SNP associated with genes in the set enriched pathways and the PPI network could be used as genomic selection targets in the Thai multibreed dairy population. This study should be continued both in this and other populations subject to a variety of environmental conditions because predicted SNP values will likely differ across populations subject to different environmental conditions and changes over time.

Abstract
AIM The circadian timing system has a rhythm and one of the roles of this system is the mediation of hormonal and metabolic adaptations to lactation. This study was conducted to determine whether the time to stage II lactogenesis differed in women who underwent cesarean section (CS) in the daytime (DT) or night-time (NT). METHODS This study was conducted at Süleymaniye Research and Education Hospital between June and December 2016. Two hundred and eighty-eight mothers who had a cesarean delivery and their healthy singleton neonates were included. Clinical and demographic data of the mothers and neonates, time of initiation of breastfeeding and time to stage II lactogenesis were analyzed according to DT or NT CS groups. RESULTS There were no statistically significant differences in age, gravida, parity, body mass index, week of gestation at birth, postoperative hemoglobin level, cesarean indications, anesthesia type, previous history of breastfeeding, transfusion need, Apgar scores or birth weight-height of neonates between the DT and NT CS groups. While the time of initiation of breastfeeding did not differ statistically in terms of DT or NT CS groups, the time to stage II lactogenesis was significantly longer in the NT CS group. CONCLUSIONS NT cesarean delivery is a risk factor for the delayed onset of lactogenesis. The results of this study may be useful to clinical practitioners counseling mothers who undergo NT cesarean delivery.
