RESUMO
INTRODUCTION: Several strategies focused on providing healthcare to premature children have been implemented. Among them, one finds breastfeeding. OBJECTIVE: Investigating the prevalence of, and factors associated with, lack of premature newborn breastfeeding at hospital discharge. METHODS: Cross-sectional study conducted with puerperal women and their preterm newborns in the public health network of Maceió, Brazil. Maternal information was obtained socioeconomic, obstetric, prenatal, and anthropometric data, through questionnaire application, where as information about newborns was collected in their medical records (gestational age at birth, sex, delivery method (vaginal birth or cesarean section), weight, and length at birth, and Apgar scores in the 1st and 5th minute of life), as well as information about the practice of breastfeeding at hospital discharge time. Poisson regression analysis in a hierarchical model was carried out to identify factors associated with the outcome of interest. Results were expressed in Prevalence Ratio (PR) and respective 95% Confidence Intervals (95%CI). RESULTS: 381 dyads were evaluated, 167 (43.8%) of them were not breastfeeding at hospital discharge time. Clinical complications observed in newborns (PR=2.20 95%CI 1.73-2.80), late postpartum contact between mother and child (PR=1.76 95%CI 1.34-2.31), low Apgar in the 1st minute of life (PR=1.44 95%CI 1.15-1.82), and small premature newborn (gestational age at birth <34 weeks) (PR=1.48 95%CI 1.18-1.84) were the factors associated with lack of breastfeeding. CONCLUSION: Lack of premature newborn breastfeeding at hospital discharge time was often observed in the current study and associated with birth-relevant factors.
INTRODUÇÃO: Diversas estratégias têm sido implementadas com enfoque na assistência à saúde da criança prematura, sendo a amamentação umas delas. OBJETIVO: Identificar a prevalência e os fatores associados à ausência de aleitamento materno na alta hospitalar de recém-nascidos prematuros. MÉTODOS: Estudo transversal realizado na rede pública de saúde de Maceió, Brasil com puérperas e seus recém-nascidos pré-termos. Foram obtidas informações maternas sobre dados socioeconômicos, obstétricos, de pré-natal e antropométricos, por meio de questionário, informações dos recém-nascidos via consulta aos prontuários médicos (idade gestacional ao nascer, sexo da criança, via de parto (vaginal ou cesariana), peso e comprimento ao nascimento e índices de Apgar no 1º e 5º minutos de vida) e sobre a prática do aleitamento materno no momento da alta hospitalar. Análise de regressão de Poisson em modelo hierarquizado foi realizada para identificação dos fatores associados ao desfecho de interesse, com os valores expressos em Razão de Prevalência (RP) e respectivos Intervalos de Confiança de 95% (IC95%). RESULTADOS: Foram avaliadas 381 díades, das quais 167 (43,8%) não estavam em aleitamento materno no momento da alta hospitalar. Intercorrências clínicas no recém-nascido (RP=2,20, IC95% 1,73-2,80), contato tardio entre mãe e filho no pós-parto (RP=1,76 IC95% 1,34-2,31), baixo Apgar no 1º minuto (RP=1,44 IC95% 1,15-1,82) e ter idade gestacional ao nascer < 34 semanas (RP=1,48 IC95% 1,18-1,84) foram fatores associados à ausência do aleitamento materno. CONCLUSÃO: A ausência de aleitamento materno na alta hospitalar de recém-nascidos prematuros foi frequente, estando associada a fatores pertinentes ao nascimento.

OBJECTIVE: To compare redox imbalance and inflammation biomarkers in umbilical cords from pregnancies with and without preeclampsia (PE) and to analyse their relationships with perinatal outcomes. METHODS: A controlled cross-sectional study was conducted in Maceió, Alagoas, Brazil, that involved pregnant women with PE and a group of women without the disease, through the application of a standardized questionnaire. After delivery, umbilical cord samples were collected to measure antioxidant defense, products from oxidative damage, and inflammation biomarkers such as myeloperoxidase (MPO), interleukin- (IL-) 6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α). Statistical analyses were performed using Stata version 13.0 software and IBM Statistical Package for the Social Sciences (SPSS) 20.0, adopting a 95% confidence level (α = 0.05), with the chi-square test, the Wilcoxon-Mann-Whitney test, and the multinomial and Poisson regression tests. RESULTS: One hundred PE pregnant women and 50 women without the disease were studied. The umbilical cords from PE pregnancies showed higher levels of reduced glutathione (GSH) (p ≤ 0.001), glutathione peroxidase (GPx) (p = 0.016), and malondialdehyde (MDA) (p = 0.028) and lower levels of IL-6 (p = 0.030) and TNF-α (p ≤ 0.001) than the other group, with some associations among these biomarkers with perinatal outcomes. CONCLUSION: The higher levels of GSH and GPx, in addition to the lower levels of IL-6 and TNF-α, found in the PE umbilical cord, may result from adaptive mechanisms to maintain the oxidative and inflammatory balance; however, despite these changes, the damage to the cell membranes was not minimized, as the MDA level was higher in women with PE than in women without the disease. This implies that a redox imbalance is present, confirming that other physiological and adaptive mechanisms are being activated to preserve foetal health. Therefore, the present work unveils an important role of the umbilical cord in controlling redox imbalance and inflammation in PE pregnancies. Our results reinforce the necessity for continuous research on GSH as a protective compound for the perinatal outcome, especially in PE women.

N-acetylcysteine (NAC) is a medicine widely used to treat paracetamol overdose and as a mucolytic compound. It has a well-established safety profile, and its toxicity is uncommon and dependent on the route of administration and high dosages. Its remarkable antioxidant and anti-inflammatory capacity is the biochemical basis used to treat several diseases related to oxidative stress and inflammation. The primary role of NAC as an antioxidant stems from its ability to increase the intracellular concentration of glutathione (GSH), which is the most crucial biothiol responsible for cellular redox imbalance. As an anti-inflammatory compound, NAC can reduce levels of tumor necrosis factor-alpha (TNF-α) and interleukins (IL-6 and IL-1ß) by suppressing the activity of nuclear factor kappa B (NF-κB). Despite NAC's relevant therapeutic potential, in several experimental studies, its effectiveness in clinical trials, addressing different pathological conditions, is still limited. Thus, the purpose of this chapter is to provide an overview of the medicinal effects and applications of NAC to human health based on current therapeutic evidence.
RESUMO
OBJECTIVE: The aim of the current study is to assess the validity and reproducibility of a FFQ focused on pregnant women living in Northeastern Brazil. DESIGN: Three 24-hour-dietary recalls (24 hR) and two FFQ were applied at 15-d intervals between research stages in order to confirm the validity and reproducibility of the FFQ. Validity assessment was based on Pearson's correlation coefficient (PCC) or Spearman's correlation coefficient (SCC) between FFQ and the mean of three 24 hR (the 24 hR was used as reference standard), whereas reproducibility assessment was based on the intraclass correlation coefficient (ICC) among FFQ, and P < 0·05 was set as significance level. SETTING: Public health network of a capital city in Northeastern Brazil. PARTICIPANTS: Overall, 100 pregnant women were included in the study. RESULTS: The PCC or SCC adopted in the validity analysis recorded the recommended values (from 0·4 and 0·7) for energy (0·44; P < 0·001), carbohydrate (0·40; P < 0·001), vitamins B2 (0·40; P < 0·001), B5 (0·40; P < 0·001), E (0·47; P < 0·001), B12 (0·48; P < 0·001), phosphorus (0·92; P < 0·001), Mg (0·81; P < 0·001), Se (0·70; P < 0·001), cholesterol (0·64; P < 0·001), saturated (0·76; P < 0·001), polyunsaturated (0·73; P < 0·001) and monounsaturated fats (0·87; P < 0·001) and fibres (0·77; P < 0·001). Mg (0·72; P < 0·001), Fe (0·65; P < 0·001), lipid (0·56; P < 0·001) and energy (0·55; P < 0·001) presented ICC within the recommended reproducibility values. CONCLUSIONS: The FFQ developed in the current study is a useful tool to assess the usual food intake of pregnant women.

This article aims to evaluate the associated factors with excessive weight gain in pregnant women from Maceió, the capital of Alagoas, Northeastern Brazil. Cross-sectional study with pregnant women attended in public health in the city of Maceió in 2014, of which socioeconomic, clinical (glycemia, capillary hemoglobin, and blood pressure measurement), dietary, and anthropometric data, including in the latter gestational weight gain, classified as insufficient, adequate and excessive according to the US Institute of Medicine, were collected. The combination of excessive weight gain with the independent variables was tested using the Poisson regression expressed by the Prevalence Ratio (PR) and a 95% confidence interval (CI95%). We studied 403 pregnant women with a mean age of 24.08 ± 6.01 years, with 19.9% of them displayed insufficient weight gain; 14.1% displayed adequate weight gain, and 66.0% displayed excessive weight gain, that was associated with maternal hyperglycemia (PR = 1.35; CI95% = 1.17 to 1.57; p < 0.001). Excessive weight gain is common among pregnant women evaluated with the association of this variable with maternal hyperglycemia.

OBJECTIVE: To compare redox and inflammatory markers between normal and PE-derived placentas and to evaluate the relationship between placental redox imbalance markers and perinatal outcomes in pregnancies with PE. METHODS: This was a cross-sectional study conducted at the maternity hospital of a university hospital in Maceio-Alagoas, Brazil, in 2017, including women diagnosed with PE and healthy pregnant women and their conceptuses. After screening, standardized questionnaires containing socioeconomic, clinical, obstetric and anthropometric data were applied. After delivery, placental samples were collected for quantification of biomarkers of redox imbalance (catalase - CAT; malondialdehyde - MDA; hydrogen peroxide - H2O2; superoxide dismutase - SOD; reduced glutathione - GSH; oxidized glutathione - GSSG; and their ratio - GSH/GSSG) and inflammation (myeloperoxidase - MPO; interleukin (IL)-6; IL-8; IL-10; and tumor necrosis factor-alpha - TNF-α). All biomarkers were evaluated via linear regression with adjustments of variables with measures of weight, length, head circumference (HC), chest circumference (CC) and gestational age of newborns at birth, considering pâ¯<â¯0.05 as significant. RESULTS: A total of 100 pregnant women with PE and 50 healthy pregnant women were studied. Higher placental levels of catalase (pâ¯=â¯0.018), SOD (pâ¯=â¯0.031), the GSH/GSSG ratio (pâ¯=â¯0.019) and IL-6 (pâ¯=â¯0.010) and lower GSSG (pâ¯=â¯0.001) were observed in pregnant women with PE than in the control group. Positive associations between placental GSH levels and body weight, HC, CC and gestational age at birth (pâ¯<â¯0.05) were identified. CONCLUSION: PE-derived placentas had high concentrations of some antioxidants (enzymes and thiols), which might be a compensation mechanism against oxidative stress. Placental GSH levels were the only biomarker, among the studied ones, related positively with beneficial perinatal outcomes, suggesting that this endogenous antioxidant plays an important role in maintaining the health of the conceptus and women with PE.

Objetivo: Avaliar a prevalência e os fatores associados à interrupção precoce do aleitamento materno exclusivo (AME) em recém-nascidos prematuros. Métodos: Coorte prospectiva com puérperas no pós-parto prematuro e seus respectivos filhos, assistidos em hospital da rede pública de saúde, em Maceió-AL, nos anos de 2016/2017. Dados clínicos e obstétricos do binômio, além de informações sobre a prática de aleitamento materno do recém-nascido após alta hospitalar, foram obtidos por aplicação de questionário padronizado. O acompanhamento foi realizado mensalmente, por seis meses. A descontinuidade do aleitamento materno exclusivo, em qualquer momento do estudo, caracterizou a interrupção precoce. O teste de regressão de Poisson foi utilizado para avaliação dos fatores associados ao desfecho, com resultados expressos por Razão de prevalência (RP) e respectivos intervalos de confiança a 95% (IC 95%) considerando p< 0,05 como significativo. Resultados: Dos 132 recém-nascidos que receberam alta hospitalar em aleitamento materno exclusivo e que foram acompanhados até os 6 meses de vida, 94 (71,2%) deles interromperam a amamentação exclusiva precocemente. Idade materna ≥35 anos foi caracterizada como fator de proteção para a interrupção precoce do aleitamento materno exclusivo [RP: 0,591 (0,350-0,997); p= 0,049] e a via de parto cesariana, como fator de risco [RP: 1,284 (1,010-1,633); p=0,041]. Conclusão: Foi alta a prevalência de interrupção do aleitamento materno exclusivo antes dos 6 meses de vida em recém-nascidos prematuros. Foram fatores associados ao desfecho, a idade materna avançada, como fator de proteção, e parto cesáreo, como fator de risco para a interrupção precoce do aleitamento materno.
Objective: To evaluate the prevalence and associated factors with early discontinuation of exclusive breastfeeding (EBF) in preterm infants. Methods: Prospective cohort with puerperal women in the premature postpartum and their respective children, assisted at a public health hospital in Maceió-AL, in 2016/2017. Clinical and obstetric data from the binomial, as well as information about the breastfeeding practice of the newborn after hospital discharge, were obtained by applying a standardized questionnaire. Follow-up was performed monthly for six months. Discontinuity of exclusive breastfeeding at any time of the study characterized early discontinuation. Poisson regression test was used to assess outcome-associated factors, with results expressed as Prevalence Ratio (PR) and 95% confidence ratios (95% CI), considering p <0.05 as significant. Results: Of the 132 newborns who were discharged from exclusive breastfeeding and who were followed up to 6 months of age, 94 (71.2%) of premature infants stopped early exclusive breastfeeding. Maternal age ≥35 years was characterized as a protective factor for early discontinuation of exclusive breastfeeding [PR: 0.591 (0.350-0.997); p = 0.049] and cesarean section as a risk factor [PR: 1.284 (1.010-1.633); p = 0.041]. Conclusion: The prevalence of exclusive breastfeeding interruption before 6 months of life in premature newborns was high. Factors associated with the outcome were advanced maternal age as a protective factor and cesarean delivery as a risk factor for early interruption of breastfeeding.
RESUMO
Abstract Objectives: to compare the assessment of the adequacy of birth weight for gestational age according to different intrauterine growth curves. Methods: across-sectional study, which analyzed gestational and neonatal information from 344 mother-newborn binomials. Birth weight data were analyzed using the International Fetal and New Born Growth Consortium for the 21st Century (INTERGROWTH-21st) and compared with the growth curves proposed by Alexander et al. and Fenton & Kim. Newborns were classified as small for gestational age (SGA), suitablefor gestational age (SUGA) or large for gestational age (LGA). Results: among the newborns, 51.2% were male, and 93.0% were born at term. Higher prevalence of SUGA and LGA and lower SGA was found by the INTERGROWTH-21st curves when compared to the references of Fenton & Kim and Alexander et al. Moderate agreement was observed in detecting birth weight by different growth curves. Conclusions: there was a lower detection of SGA infants and a higher screening, especially of LGA infants, in the INTERGROWTH-21st evaluation, when compared to the growth curves of Fenton & Kim and Alexander et al.

Abstract Objectives: to compare the adverse perinatal outcomes in pregnancies of adolescents and elderly women of public health network. Methods: a cross-sectional study carried out with pregnant women at the extremes of reproductive age according to the classification of the Brazilian Ministry of Health (adolescents those aged ≤19 years and those who were older than 35 years) and their newborns. Socioeconomic data (income, schooling, occupation and marital status), as well as clinical (diseases), anthropometric (maternal BMI) and perinatal (gender, weight, length, Apgar and gestational age) data were collected, and Poisson regression in hierarchical model was performed, with the results in Ratio of Prevalence (PR) and its respective Confidence Interval at 95% (95% CI). Results: when comparing adolescent and elderly women, 38.7% vs 54.6% (PR=0.71, CI=0.54-0.94, p=0.002) were observed, respectively, cesarean deliveries; 37.8% vs 25.2% (PR=0.83, CI=0.58-1.19, p=0.332) preterm births; 16.6% vs 20.5% (RP=1.07, CI=0.78-1.46, p=0.666) births of small infants for gestational age (SGA); 18.0% vs 15.3% (RP=1.01, CI=0.69-1.47, p=0.948) births of large-for-gestational-age newborns (LGA); 32.2% vs 34.7% (RP=1.08, CI=0.82-1.42, p=0.578), low birth weight infants and 28.5% vs 42.9% (RP=1.18, CI=0.91-1.54, p=0.201) with high birth length. Conclusions: When compared with adolescent women, pregnant women of advanced age presented a higher frequency of cesarean deliveries.
