Sex-Dependent Variations in Hypothalamic Fatty Acid Profile and Neuropeptides in Offspring Exposed to Maternal Obesity and High-Fat Diet.

Maternal obesity and/or high-fat diet (HF) consumption can disrupt appetite regulation in their offspring, contributing to transgenerational obesity and metabolic diseases. As fatty acids (FAs) play a role in appetite regulation, we investigated the maternal and fetal levels of FAs as potential contributors to programmed hyperphagia observed in the offspring of obese dams. Female mice were fed either a control diet (CT) or HF prior to mating, and fetal and maternal blood and tissues were collected at 19 days of gestation. Elevated levels of linoleic acid were observed in the serum of HF dams as well as in the serum of their fetuses. An increased concentration of eicosadienoic acid was also detected in the hypothalamus of female HF-O fetuses. HF-O male fetuses showed increased hypothalamic neuropeptide Y (Npy) gene expression, while HF-O female fetuses showed decreased hypothalamic pro-opiomelanocortin (POMC) protein content. Both male and female fetuses exhibited reduced hypothalamic neurogenin 3 (NGN-3) gene expression. In vitro experiments confirmed that LA contributed to the decreased gene expression of Pomc and Ngn-3 in neuronal cells. During lactation, HF female offspring consumed more milk and had a higher body weight compared to CT. In summary, this study demonstrated that exposure to HF prior to and during gestation alters the FA composition in maternal serum and fetal serum and hypothalamus, particularly increasing n-6, which may play a role in the switch from POMC to NPY neurons, leading to increased weight gain in the offspring during lactation.

Temperature curve of raw human milk heated by different methods: experimental study.

OBJECTIVE: To analyze the temperature curve of raw or pasteurized human milk exposed to different heating methods. METHOD: Experiments with volumes of 5 ml to 100 ml of human milk were carried out between 2016 and 2021 and analyzed according to the exposure time by different heating methods. Descriptive statistics included the calculation of means, medians, minimum and maximum values, measures of dispersion and standard deviation. RESULTS: The thermal curve made it possible to identify the heating of human milk close to body temperature when subjected to a water bath and microwaves. Milk exposed to room temperature (21°C) was unable to reach this temperature. When heated in a water bath at 40°C, smaller volumes reached body temperature between 3 and 5 minutes, while in a microwave at 50% power, practically all volumes reached temperature. CONCLUSION: The temperature curves of raw or pasteurized human milk were constructed, and it was possible to verify its behavior using different heating methods for administering the food in a neonatal intensive care unit, considering the volume, type and time of heating and temperature.

Initial nipple damages in breastfeeding women: analysis of photographic images and clinical associations / Lesiones tempranas del pezón derivadas de la lactancia materna: análisis de imágenes fotográficas y asociaciones clínicas / Lesões mamilares precoces decorrentes da amamentação: análise de imagens fotográficas e associações clínicas

ABSTRACT Objective: to analyze the initial nipple damage degree by breastfeeding practice and to associate findings with clinical manifestations of breastfeeding women. Methods: a retrospective, cross-sectional study with primary data and photographic images database from two randomized clinical trials. Photographic images were analyzed by two independent evaluators using the Nipple Trauma Score. For analysis, the chi-square, Mann-Whitney tests and Kappa coefficient were applied. Results: 115 breastfeeding women and their respective 186 photographic images were analyzed. The degree of agreement of evaluators using the Nipple Trauma Score was 93.6%. The nipple pain score during breastfeeding was moderate and compromised more than 25% of the nipple surface area. Conclusions: assistance to breastfeeding women should prioritize nipple pain intensity instead of the nipple damage size.

Factors associated with postpartum depression symptoms among postpartum women in five countries during the COVID-19 pandemic: an online cross-sectional study.

BACKGROUND: This study aimed to examine factors associated with postpartum depression (PPD) symptoms during the COVID-19 pandemic among postpartum women in five countries, a subject that has not been investigated thus far. METHODS: A multi-country, cross-sectional, online survey was conducted with a convenience sample of 3,523 postpartum women in Brazil, South Korea, Taiwan, Thailand, and the United Kingdom, from July to November 2021. Sociodemographic and obstetric data, food insecurity, COVID-19 positive status, COVID-19 vaccination, infant feeding, breastfeeding belief score, and social support were investigated. PPD and social support were measured using the Edinburgh Postnatal Depression Scale and Maternal Social Support Scale, respectively. Descriptive statistics, chi-squared tests, and t-tests were used to identify associations with PPD symptoms. A binary logistic regression model was used to identify explanatory factors associated with PPD and adjusted odds ratios (OR) and 95% confidence intervals (CIs) were calculated. RESULTS: Women in Taiwan (AOR = 0.5; 95%CI 0.34, 0.73) and Thailand (AOR = 0.68; 95%CI 0.46, 0.99) had a lower risk of PPD symptoms than those in Brazil. In addition, women with planned pregnancies had a lower risk of PPD (AOR = 0.74; 95%CI 0.60, 0.91). Younger women (AOR = 1.62; 95%CI 1.05, 2.51), health problems during pregnancy, delivery, or postpartum (AOR = 1.71; 95%CI 1.42, 2.06), and no change or worse food insecurity during COVID-19 (AOR = 1.66; 95%CI 1.21, 1.27 for no change and AOR = 1.68; 95%CI 1.27, 1.23, respectively) presented a higher likelihood of having PPD. Feeding babies with expressed human milk (AOR = 1.25; 95%CI 1.03, 1.50) and/or complementary food (AOR = 1.51; 95%CI 1.17, 1.94) were associated with PPD symptoms. Women who received low (AOR = 7.74; 95%CI 5.43, 11.03) or medium support (AOR = 3.25; 95%CI 2.71, 3.88) had higher likelihoods of PPD. CONCLUSION: PPD symptoms during the pandemic were high in young women, particularly Brazilian women, with health problems in the puerperal pregnancy cycle who fed their babies expressed breast milk and/or complementary food. Low social support also impacted PPD symptoms. This study highlights the need for the professional screening for PPD and provision of virtual or personal support.

Abstract Objective To analyze the relationship of maternal anxiety symptoms with breastfeeding self-efficacy and duration of exclusive breastfeeding. Methods Prospective cohort study developed in a Breastfeeding Center of a university hospital in the city of São Paulo. The sample consisted of 83 postpartum women in follow-up for 210 days after delivery. The Anxiety Subscale of the Edinburgh Postnatal Depression Scale and the Breastfeeding Self-Efficacy Scale were used. Results The mean total score for anxiety was 3.76 points and for maternal self-efficacy to breastfeed was 128.58. Over the months, anxiety symptoms and breastfeeding self-efficacy showed similar behavior and were not statistically significant. The following risk factors were associated with the increase in anxiety symptoms: abortion, previous history of depression, complaints about oneself, unsatisfactory family and marital relationships, worsening of the relationship with the partner after the baby was born and lower maternal breastfeeding self-efficacy, reflected in the technique domain and intrapersonal thoughts domain. The time between cessation of exclusive breastfeeding and anxiety was not statistically different. Conclusion The investigated postpartum women had a high prevalence of anxiety symptoms, with significant interference in the perception and confidence in their ability and maternal capability to successfully breastfeed the baby. There was no association between anxiety symptoms and early breastfeeding cessation.

Protective measures feasibility for infants of low income SARS-CoV-2 positive breastfeeding mothers: a prospective multicenter cohort study.

AIM: The aim was to evaluate the feasibility of protective measures for infants of low-income SARS-CoV-2 positive breastfeeding mothers. BACKGROUND: Breastfeeding mothers with SARS-CoV-2 positive should avoid exposing the infant through protective measures (PM), but it could be challenging in a low-income population. METHODS: A prospective, multicenter study was conducted between July and October 2020 (BRACOVID). The participants were recruited at birth and interviewed through a structured questionnaire at seven and 14 days in the home environment. The feasibility of PM during breastfeeding at home was defined by guidelines recommendations (mask using, handwashing, and distancing from newborn when not breastfeeding). Three groups according to the feasibility of guidelines: complete guidelines feasibility (CG): all PM; partial guidelines feasibility (PG): at least one PM feasible; no guidelines (NG): infeasibility to all of PM. Flu-like neonatal symptoms, mothers' breastfeeding practices. We evaluated the association between PM feasibility and socioeconomic factors. RESULTS: 117 infected mothers from 17 Brazilian hospitals were enrolled. 47 (40%) mothers followed all recommendations, 14 (11.9%) could not practice at least one recommendation, and 50 (42.7%) did not execute any of them. The breastfeeding rate was 98%. Factors associated with infeasibility were monthly family income < 92.7 dollars/person, high housing density (>1 inhabitant/room), teenage mothers, responsive feeding, and poor schooling. Regarding infants' flu-like symptoms, 5% presented symptoms at fourteen days (NG group). CONCLUSION: The guidelines were not applied to infants of SARs-CoV-positive mothers in 54.6% of the dyads since the recommendations were unviable in their environments. During pandemics, we should look for feasible and effective guidelines to protect neonates from low-income populations. IMPLICATIONS FOR NURSING MANAGEMENT: Poor socioeconomic conditions lead to the unfeasibility of protective measures for infants of low-income SARS-CoV-2 positive breastfeeding mothers during the isolation period in the pandemics. The orientations and the support provided to dyad should consider the socioeconomic factors to guide feasible measures in the home environment and promote adequate protections; only an individual approach will allow a safe environment for low-income infants.

Impact of COVID-19 on breastfeeding intention and behaviour among postpartum women in five countries.

BACKGROUND: Studies regarding the impact of COVID-19 on breastfeeding have mostly used single- country samples or a qualitative design. AIM: The objective of this study was to examine breastfeeding intention during pregnancy and breastfeeding behaviour among postpartum women in five countries during the COVID-19 pandemic and the associated factors. METHODS: An online questionnaire survey was conducted in Thailand, the United Kingdom, South Korea, Taiwan, and Brazil from July through November 2021. The study participants included 3253 mothers within six months of birth. FINDINGS: About 90% of participants intended to breastfeed during pregnancy and 85.7% reported breastfeeding in the past 24 h. More than half reported their breastfeeding duration being as planned or longer despite COVID-19. Multivariate logistic regression models showed that being multiparous, ever tested COVID-19 positive, and having positive breastfeeding beliefs were associated with increased odds for intention to breastfeed during pregnancy. Lower maternal educational level, being primiparous, ever tested COVID-19 positive, and experiencing food insecurity were associated with decreased odds for breastfeeding duration being as planned or longer. Vaginal birth, currently working or on maternity leave, breastfeeding beliefs, breastfeeding support from spouse/partner/friend/relative, online support groups, and in-person or telephone contact with healthcare professionals were associated with increased odds for breastfeeding duration being as planned or longer. CONCLUSION: Breastfeeding intention and behaviour remained high during the COVID-19 pandemic. Online support groups and telephone contact with health professionals were effective during the pandemic.

Abstract Objective To analyze the duration of breastfeeding and the factors associated with total weaning of infants aged six to 23 months and 29 days living in the municipality of Cruzeiro do Sul, in the Brazilian Western Amazon. Methods A cross-sectional study conducted during the National Multi-Vaccination Campaign in 2016 and Against Influenza in 2017. The sample was estimated by clusters. The data was collected with the mothers or guardians of 679 infants who attended vaccination campaigns and answered a questionnaire. Kaplan-Meier survival analysis was used, and Cox regression was used for the factors associated with total weaning. A 5% significance level was considered for all statistical tests. Results Breastfeeding was practiced by 65.3% of the infants, whose mean age was 13.7 months (SD± 4.9 months). The mean total weaning time was 16.7 months (95% CI: 16.06 - 17.36) and the median of 22 months, which is the probability of duration of breastfeeding up to two years old in 49.7%. The factors associated with total weaning were previous breastfeeding experience for less than six months, not breastfeeding in the first hour of life, pacifier use and bottle-feeding. Conclusion The duration of breastfeeding was below the recommended. The factors associated with total weaning of infants between six and 23 months are related to previous maternal experience, early initiation of breastfeeding and the use of artificial nipples.

OBJECTIVES: to construct and validate a classification of nipple and areola complex lesions resulting from breastfeeding, according to content and appearance. METHODS: this is a methodological study, developed in four stages: operational definition, instrument construction, content and appearance validation. The Delphi technique and a Likert-type scale were used to validate content and appearance, through the participation of ten and sixteen judges, respectively. For analysis, Content Validity Index and Kappa Coefficient were applied. RESULTS: Content Validity Index obtained an overall value of 0.93 and, for appearance, 0.94. Kappa values ranged between 0.46 and 1. The high rates of agreement among judges demonstrated the quality of the proposed content validity. CONCLUSIONS: the Nipple and Areola Complex Lesions Classification Instrument developed obtained acceptable values of its indexes, proving to be valid in terms of content and appearance.

Quasi-Experimental study of effects of lighting on rest, activity and melatonin in postpartum women.

OBJECTIVES: to compare the parameters of the activity/rest cycle of early postpartum breastfeeding women under a controlled and uncontrolled long wavelength ray light regimen. METHODS: quasi-experimental study with breastfeeding women and their babies during postnatal rooming-in, São Paulo, Brazil. Participants were allocated to either an experimental (intervention) or a comparison group. The intervention involved exposure of the woman in a controlled room with artificial long wavelength ray light at night. Each woman's level of 6-sulfatoxymelatonin at 24 hours and activity/rest times was analyzed. RESULTS: the mean activity/rest times of women in the experimental and comparison groups were similar. The mean percentages of total load of 6-sulfatoxymelatonin during the day and night were similar (p=0.09). At 24 hours, the experimental group presented a significantly lower mean percentage of total load compared to the comparison group (p=0.04). CONCLUSIONS: women who stayed in the room with long-wavelength artificial light showed no difference in activity/rest and 6-sulfatoxymelatonin levels in the early postpartum period.

Food diversity among indigenous children from two municipalities of the Brazilian Western Amazon. / Diversidade alimentar de crianças indígenas de dois municípios da Amazônia Ocidental brasileira.

Our aim was to explore the feeding practices of indigenous children younger than two years old, living in Cruzeiro do Sul and Mâncio Lima, in Acre, Brazil. A cross-sectional study was conducted with indigenous children of the Katukina (Cruzeiro do Sul), Nukini, Nawa and Poyanawa (Mâncio Lima) ethnicities in October 2013. We used a structured questionnaire on the food consumption of the day before the collection, based on the food indicators proposed by the Ministry of Health. A total of 94 children (50% Katukina, 27% Poyanawa, 13% Nukini, and 10% Nawa) were studied. Among children under 6 months of age, although the majority was breastfed, 42.1% drank water, 15.8%, savory food, and 11.1%, local cuisine. In the age groups of 6 to 12 months and 13 to 23 months, a high consumption of ultra-processed foods was identified (52.6% and 28.6% respectively), while the consumption of complementary food was insufficient (33% of fruits and 25% of savory food between 6 and 13 months, and 41.2% of fruits and 19.6% of savory food between 13 and 23 months). The feeding profile of these indigenous children was inadequate for their age, revealing a concerning situation for this population.

Objetivou-se explorar a prática alimentar das crianças indígenas de zero a dois anos, residentes nos municípios de Cruzeiro do Sul e Mâncio Lima no Acre. Realizou-se estudo transversal com crianças indígenas das etnias Katukina (Cruzeiro do Sul), Nukini, Nawa e Poyanawa (Mâncio Lima) em outubro de 2013. Utilizou-se um questionário estruturado sobre o consumo alimentar do dia anterior à coleta, baseado nos indicadores alimentares propostos pelo Ministério da Saúde. Estudou-se 94 crianças (50% da etnia Katukina, 27% Poyanawa, 13% Nukini e 10% da Nawa). As crianças menores de 6 meses de idade, apesar da maioria receber leite materno, 42,1% delas consumiam água, 15,8% comida de sal e 11,1% preparados típicos da região. Nas faixas de idade de 6 a 12 meses e 13 a 23 meses identificou-se um alto consumo de alimentos ultraprocessados (52,6% e 28,6% respectivamente) enquanto que o consumo de alimentos complementares relevou-se insuficiente (33% de frutas e 25% de comida de sal na faixa de 6 a 13 meses e 41,2% de frutas e 19,6% de comida de sal na faixa de 13 a 23 meses). O perfil alimentar das crianças indígenas mostrou-se inadequado para a idade, refletindo uma situação preocupante na saúde infantil desta população.

Breastfeeding Practices and Problems Among Obese Women Compared with Nonobese Women in a Brazilian Hospital.

Background: Women who are obese have lower rates of breastfeeding initiation and duration and are less likely to breastfeed exclusively compared with women who are not obese. To develop programs to improve breastfeeding practices among this group of women, we investigated the association between maternal obesity and breastfeeding practices and problems in the first days postpartum. Methods: We analyzed medical records from postpartum women at a rooming-in maternity ward in State of São Paulo, Brazil, between 2016 and 2018. We included those who had intended to exclusively breastfeed, had given birth to a singleton and were admitted to rooming-in. We analyzed exclusive breastfeeding and nonexclusive breastfeeding each day of hospitalization and the presence of breastfeeding problems, comparing women in the obese category (body mass index [BMI] ≥30 kg/m2) to normal and overweight women (≥18.6 to ≤29.9 kg/m2). Results: Two hundred and twenty-four postpartum women participated, including 86 women in the obese category. More than 50% of women with obesity reported a breastfeeding problem in the first and second postpartum days (p = 0.026 and p = 0.017, respectively) compared with the 41% and 38% nonobese group. Children of obese women were 2.8 times more likely to have poor latch during breastfeeding (95% confidence interval [CI]: 1.29-6.10) compared with the nonobese group on the third day. Conclusion: Maternal obesity increased the probability of breastfeeding difficulties and nonexclusive breastfeeding at discharge. Professionals need to support breastfeeding techniques in the days immediate after delivery to improve breastfeeding outcomes for mothers with obesity.

The effect of a single irradiation of low-level laser on nipple pain in breastfeeding women: a randomized controlled trial.

Photobiomodulation with low-level laser therapy (PBM-LLLT) has been introduced as a new tool to relieve nipple pain and repair nipple damage in breastfeeding women; however, evidence is needed to assess its effectiveness. The aim was to evaluate the effect of a single application of PBM-LLLT for breastfeeding women with nipple pain and damage; side effects were also collected. We conducted a randomized double-blinded controlled trial with women with nipple damage who were exclusively breastfeeding and rooming-in at Amparo Maternal maternity service, São Paulo, Brazil (May 2016 to May 2017). Women were randomly assigned into laser (n = 40) or control group (n = 40). Intervention was a single irradiation (660 nm, 100 mW, 2 J, 66.66 J/cm2, 3.3 W/cm2, 20 s of irradiation, punctual, and continuous mode) applied directly. Women reported pain levels at recruitment (before and immediately after irradiation), 6 and 24 h after the treatment. Pain level during a breastfeed was assessed using the Visual Analogue Scale (0 to 10). The primary outcome was the level of nipple pain immediately after the laser irradiation. Data were analyzed using hierarchical model and Wald test. At baseline, pain levels were similar (mean of 7.4 in laser group and 7.1 in control group). Women's perception of pain reduced approximately one point in both groups. Thirty-one percent of participants in the laser group (11/36) reported secondary effects, such as tingling (10/36) and pricking (2/36). The laser protocol of a single application was not effective in reducing pain in women with damaged nipples. Tingling sensation may be experienced by women receiving laser treatment for nipple damage.
