Panoramic snapshot of serum soluble mediator interplay in pregnant women with convalescent COVID-19: an exploratory study.

Introduction: SARS-CoV-2 infection during pregnancy can induce changes in the maternal immune response, with effects on pregnancy outcome and offspring. This is a cross-sectional observational study designed to characterize the immunological status of pregnant women with convalescent COVID-19 at distinct pregnancy trimesters. The study focused on providing a clear snapshot of the interplay among serum soluble mediators. Methods: A sample of 141 pregnant women from all prenatal periods (1st, 2nd and 3rd trimesters) comprised patients with convalescent SARS-CoV-2 infection at 3-20 weeks after symptoms onset (COVID, n=89) and a control group of pre-pandemic non-infected pregnant women (HC, n=52). Chemokine, pro-inflammatory/regulatory cytokine and growth factor levels were quantified by a high-throughput microbeads array. Results: In the HC group, most serum soluble mediators progressively decreased towards the 2nd and 3rd trimesters of pregnancy, while higher chemokine, cytokine and growth factor levels were observed in the COVID patient group. Serum soluble mediator signatures and heatmap analysis pointed out that the major increase observed in the COVID group related to pro-inflammatory cytokines (IL-6, TNF-α, IL-12, IFN-γ and IL-17). A larger set of biomarkers displayed an increased COVID/HC ratio towards the 2nd (3x increase) and the 3rd (3x to 15x increase) trimesters. Integrative network analysis demonstrated that HC pregnancy evolves with decreasing connectivity between pairs of serum soluble mediators towards the 3rd trimester. Although the COVID group exhibited a similar profile, the number of connections was remarkably lower throughout the pregnancy. Meanwhile, IL-1Ra, IL-10 and GM-CSF presented a preserved number of correlations (≥5 strong correlations in HC and COVID), IL-17, FGF-basic and VEGF lost connectivity throughout the pregnancy. IL-6 and CXCL8 were included in a set of acquired attributes, named COVID-selective (≥5 strong correlations in COVID and <5 in HC) observed at the 3rd pregnancy trimester. Discussion and conclusion: From an overall perspective, a pronounced increase in serum levels of soluble mediators with decreased network interplay between them demonstrated an imbalanced immune response in convalescent COVID-19 infection during pregnancy that may contribute to the management of, or indeed recovery from, late complications in the post-symptomatic phase of the SARS-CoV-2 infection in pregnant women.

Breastfeeding success and its relation to maternal pain, behaviour, mental health, and social support.

OBJECTIVE: We aimed to understand the maternal experience of breastfeeding onset and how psychological, social and clinical variables as pain during breastfeeding, may interfere with it. METHODS: A cross-sectional study investigated 395 post-delivery women able to breastfeed from 48 hours to 6 days for unpleasant breastfeeding, maternal stress during pregnancy and postnatal mental state. Social Readjustment Rating Scale evaluated prenatal maternal stress. Perceived Maternal Parenting Self-Efficacy Scale, Pain Catastrophizing Scale - Parent version, and Edinburgh Postnatal Depression Scale evaluated maternal mental state. RESULTS: Unpleasant breastfeeding experience showed to be positively related to the longer number of days the pain lasts; late onset of breastfeeding; less search for information about pregnancy and baby care (p < .01); lower catastrophizing behaviour towards infant´s stress and C-section delivery (p < .04). Pain levels were positively correlated to longer periods of pain, later onset of antenatal consultations and depression (p < .05). Binary logistic regression pointed to the effects of lower self-efficacy and pain in breastfeeding, higher depression levels, gestational stress, labour adversities and success in breastfeeding. CONCLUSIONS: The relationship among maternal perceived self-efficacy, anxious and depressive thoughts, catastrophizing behaviours, and unpleasant breastfeeding need to be evaluated to elucidate the best health professional intervention.

The use of the cambridge neuropsychological test automated battery for people born with Down syndrome and those born premature: A comparative systematic review.

This review aimed to investigate the use of the Cambridge Neuropsychological Automated Testing Battery (CANTAB) for people at risk of cognitive impairment, especially those born with Down syndrome and those born preterm. Six databases were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards, in addition to the bibliography index listed in the CANTAB site. Twenty four studies regarding Down syndrome and 17 regarding prematurity were reviewed and are here described. Both cognitive profiles were described, and their performance was compared on specific tasks and CANTAB tests. In this battery of tests, people with Down syndrome usually present impaired key cognitive domains, such as episodic memory and recognition memory. Results were presented considering general aspects described in the studies, specific findings such as dementia, the role of genetics, and cognitive profile, among other descriptions. Comparability between both populations in future studies is discussed.

Cerebrospinal fluid analysis of pregnant women at early stages of COVID-19.

OBJECTIVE: To determine the presence or absence of SARS-CoV-2 in the cerebrospinal fluid of pregnant women at early stages of COVID-19. MATERIALS AND METHODS: We conducted a prospective observational study with pregnant women undergoing cesarean section and real-time polymerase chain reaction to SARS-CoV-2 was performed in the cerebrospinal fluid in the early stages of COVID-19. RESULTS: Fourteen pregnant women, whose COVID-19 symptoms started between four to 18 days prior to delivery, were included. Eleven of the women reported anosmia, dysgeusia, and headaches and there were two fatal cases. SARS-Cov-2 was not present in the cerebrospinal fluid of these COVID-19 patients with early neurological symptoms, even in severe cases. CONCLUSION: Our study suggests that peripheric cell damage and parainfectious phenomena may predominate over direct central nervous system injury in the pathophysiology of COVID-19 related early neurological symptoms on pregnant women.

The Use of Virtual and Computational Technologies in the Psychomotor and Cognitive Development of Children with Down Syndrome: A Systematic Literature Review.

Individuals with Down syndrome (DS) have numerous comorbidities due to trisomy 21. However, virtual reality-based therapy (VRT) has been used nowadays as a learning and visual motor tool in order to facilitate the development and learning process of this group. The aim of this article was to carry out an integrative review of the literature on the use of virtual and computational technologies in the stimulation of children with DS. A search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) through single key words or their combinations using AND or OR operators: "Down syndrome" AND ("development" OR "cognition" OR "visomotor" OR "digital game" OR "virtual reality"). Eventually, 18 articles were included in our review. The games used in the research were able to stimulate, through the visual field, global motor skills, balance, body scheme and spatial organization, in addition to the learning of mathematical concepts, in order to directly influence the autonomous life activities, language skills, social skills and educational aspects of people with DS. Electronic games contribute to the teaching-learning relationship and stimulate neuropsychomotor and cognitive functions and development in children with DS.

Olfactory sensory and perceptual evaluation in newborn infants: A systematic review.

Fetuses are able to process olfactory stimuli present in the womb and continue to show a preference for these odors for months after birth. Despite the accumulated knowledge about their early ability to perceive odors, there is a lack of validated scales for odor response in newborns. The evaluation of reactions of the olfactory system to environmental stimuli in infants has been defined by methodological theoretical approaches of experimental and clinical assessment tools. These approaches are mainly based on psychophysical approaches and predominantly use behavioral and physiological measures. Examples can be found in studies describing early abilities of newborn babies for behaviors or heart rate variability showing memory of maternal food preferences or mother's breast milk. This systematic review aimed to determine whether validated odor assessment tools can be feasibly used in studies. Particularly in light of the current COVID-19 pandemic and evidence of associated olfactory impairment resulting from SARS-COV-2 infection, the study is also motivated by the need for tools to assess olfactory function in neonates.

Olfactory sensory evaluation in newborn children of women infected with COVID-19 during pregnancy / Avaliação sensorial olfativa em crianças recémnascidas de mulheres infectadas com COVID-19 durante a gravidez

INTRODUCTION: In adults, olfactory loss is one of the earliest and most frequent acute clinical manifestations of SARS-CoV-2 infection. The number of children infected with SARS-CoV-2 is relatively small, perhaps due to the lower expression of Angiotensin Converting Enzyme 2 (ACE2) in children compared to adults. Little is known about foetal impairment in mothers infected with SARS-CoV-2. This paper describes an ongoing scientific project on smell perception in infantsOBJECTIVE: The goal of the study is to develop and validate a behavioural evaluative scale of olfactory perception in healthy newborns and to apply this scale to newborn children of women infected with COVID-19 during pregnancy comparing to newborn children of women without COVID-19 infection history, in order to compare these groupsMETHODS: This is a retrospective comparative analytical cohort study of 300 newborns exposed and unexposed to COVID-19 during pregnancy. The data collection will follow the experimental procedure in a previous study that explored odours of the maternal breastmilk, vanilla (sweet) and distilled water (neutral). A coffee smell was implemented as an addition to this previous study in order to include acid/bitterness category to the categories of stimuliDISCUSSION: It is feasible to argue the hypothesis of the involvement of the foetus' olfactory bulb as one of the indelible pathophysiological manifestations to the clinical diagnosis of COVID-19 with neurosensory olfactory deficit in foetuses and newborns affected by intrauterine infection. This study aims to investigate if newborn children of women infected with COVID-19 during pregnancy have olfactory sensory changes. The clinical trial was registered in the Brazilian Registry of Clinical Trials (ReBEC- RBR-65qxs2

INTRODUÇÃO: Em adultos, a perda olfativa é uma das manifestações clínicas agudas mais precoces e frequentes da infecção por SARS-CoV-2. O número de crianças infectadas com SARS-CoV-2 é pequeno, talvez devido à menor expressão da Enzima Conversora da Angiotensina 2 (ACE2) em crianças em comparação com adultos. Pouco se sabe sobre o comprometimento fetal em mães infectadas com SARS-CoV-2. Este artigo descreve um projeto em andamento sobre a percepção olfativa em bebês recém-nascidosOBJETIVO: o objetivo do presente estudo é desenvolver e validar uma escala de avaliação comportamental da percepção olfativa em recém-nascidos saudáveis e aplicá-la a recém-nascidos de mulheres infectadas com COVID-19 durante a gravidez e comparar a recém-nascidos de mulheres sem histórico de infecção por COVID-19MÉTODO: Este é um estudo de coorte analítico comparativo retrospectivo de 300 recém-nascidos expostos e não expostos ao COVID-19 durante a gravidez. A coleta de dados seguirá o procedimento experimental de estudo anterior que explorou odores do leite materno, baunilha (doce) e água destilada (neutro). Um cheiro de café foi implementado como um complemento a este estudo anterior, a fim de incluir a categoria ácido / amargo nas categorias de estímulosDISCUSSÃO: É possível argumentar a hipótese do envolvimento do bulbo olfatório do feto durante a vida intrauterina como uma das manifestações fisiopatológicas indeléveis para o diagnóstico clínico de COVID-19 com déficit olfatório neurossensorial em fetos e recém-nascidos afetados por infecção intrauterina. Este estudo tem como objetivo investigar se filhos recém-nascidos de mulheres infectadas com COVID-19 durante a gravidez apresentam alterações sensoriais olfativas. O ensaio clínico foi registrado no Registro Brasileiro de Ensaios Clínicos (ReBEC- RBR-65qxs2

Pregnancy Outcomes and Child Development Effects of SARS-CoV-2 Infection (PROUDEST Trial): Protocol for a Multicenter, Prospective Cohort Study.

BACKGROUND: A growing body of evidence suggests that SARS-COV-2 infection during pregnancy may affect maternal-fetal outcomes and possibly result in implications for the long-term development of SARS-CoV-2-exposed children. OBJECTIVE: The PROUDEST (Pregnancy Outcomes and Child Development Effects of SARS-CoV-2 Infection Study) is a multicenter, prospective cohort study designed to elucidate the repercussions of COVID-19 for the global health of mothers and their children. METHODS: The PROUDEST trial comprises 2 prospective, sequential substudies. The PREGNANT substudy will clinically assess the effects of SARS-CoV-2 infection on pregnancy, childbirth, and puerperium from a mechanistic standpoint to elucidate the pregnancy-related inflammatory and immunological phenomena underlying COVID-19. Pregnant women aged 18-40 years who have been exposed (proven with laboratory tests) to SARS-CoV-2 (group A; n=300) will be compared to control subjects with no laboratory evidence of in-pregnancy exposure to the virus (group B; n=300). Subjects exposed to other infections during pregnancy will be excluded. The BORN substudy is a long-term follow-up study that will assess the offspring of women who enrolled in the prior substudy. It will describe the effects of SARS-CoV-2 exposure during pregnancy on children's growth, neurodevelopment, and metabolism from birth up to 5 years of age. It includes two comparison groups; group A (exposed; n=300) comprises children born from SARS-CoV-2-exposed pregnancies, and group B (controls; n=300) comprises children born from nonexposed mothers. RESULTS: Recruitment began in July 2020, and as of January 2021, 260 pregnant women who were infected with SARS-CoV-2 during pregnancy and 160 newborns have been included in the study. Data analysis is scheduled to start after all data are collected. CONCLUSIONS: Upon completion of the study, we expect to have comprehensive data that will provide a better understanding of the effects of SARS-CoV-2 infection and related inflammatory and immunological processes on pregnancy, puerperium, and infancy. Our findings will inform clinical decisions regarding the care of SARS-CoV-2-exposed mothers and children and support the development of evidence-based public health policies.

Adaptation and validation of the EVENDOL scale to assess pain in neonates in Portuguese language.

BACKGROUND: EVENDOL scale (from the French Evaluation Enfant Douleur) is used to evaluate pain in children in any situation covering a wider age group than other pain scales (birth up to seven years). This study aimed to evaluate pain in hospitalized newborns, to adapt and validate the EVENDOL to Brazilian Portuguese. STUDY DESIGN: Cross-sectional, cross-cultural adaptation and validation study in a convenience sample from a tertiary hospital, Brazil. EVENDOL was translated and tested for reliability and validity using the PIPP and NFCS scales for comparison. For reliability testing, two observers independently evaluated 117 nociceptive procedures from 87 newborns. Internal consistency coefficient Cronbach's alpha, internal class agreement coefficient, and Kappa factor were appropriately measured. RESULTS: The scale's internal consistency reached a value of 0.82, and the estimates of internal consistency and reliability also reached acceptable or very good values. Two-way ANOVA determined statistically significant effect of gestational age on the total score of the EVENDOL (F = 4.14; p = 0.045), younger infants had the lowest values, as lower values of Apgar-5° minute lowered the indicator "Interaction with the Environment" (F = 5.066; p = 0.027). CONCLUSIONS: EVENDOL proved to be an easily applied tool and it was psychometrically robust, reliable and valid for use with both premature and term hospitalized newborns, who were clinically stable, being Apgar score and gestational age relevant factors. It is a reliable method of identifying pain in babies who need more support from the hospital staff and now is available for use in Portuguese language. TWEETABLE ABSTRACT: The EVENDOL pain scale is now validated for babies born at term and prematurely in Portuguese Language allowing its use in all Lusophone countries.

Auditory processing disorder evaluations and cognitive profiles of children with specific learning disorder.

OBJECTIVE: This study investigated the auditory sensory-perceptual level of specific learning disorder (SLD) and explored relationships among neuropsychological assessments for SLD, auditory processing, and short and long latencies of auditory event-related potentials (ERPs). METHODS: Fifteen children (7-14 years old) comprised the control group; 34 children comprised the SLD group. Audiologic assessments included tone audiometry, acoustic immittance measurements, acoustic reflex, central auditory processing, brainstem evoked response audiometry, and long latency potentials (P3 and N2). Children's intelligence levels were assessed with 2 intelligence batteries, 1 verbal and 1 non-verbal, as well as with visuomotor skills. RESULTS: Multiple regression showed a significant interaction effect of APE tests and P3/N2 over Wechsler Scale performance in freedom of distractibility indexes and multiple subtests. Errors in the Bender Visual Motor Gestalt Test were predicted by lower parental education, lower performance in APE tests: dichotic digits and pediatric/synthetic sentence identification-ipsilateral, and longer P3/N2 latencies, particularly regarding integration and rotation distortions. CONCLUSIONS: Children with altered auditory processing exhibit a specific cognitive profile, including lower verbal and spatial reasoning performance, that is sensitive to parental education level. SIGNIFICANCE: Children with SLD should undergo a complete multimodal examination to identify their specific difficulties and needs.

Comparison of conventional, amplitude-integrated and geodesic sensor net EEG used in premature neonates: a systematic review.

INTRODUCTION: The use of methods to evaluate cortical activity in neonates has great importance in modern medicine, as it allows the observation and evaluation of several clinical aspects, which guarantees that the health team has knowledge about possible intervention measures that may be necessary in the treatment of newborns. OBJECTIVE: This systematic review aimed to compare the main technologies available for the evaluation of brain functions in neonates, among them: the conventional electroencephalogram (EEG), the amplitude-integrated electroencephalogram (aEEG) and the geodesic sensor net EEG. METHODS: A search was conducted forarticles from national and international periodicals included in the Web of Science, LILACS, SciELO and Medline electronic databases. RESULTS: The search found 39 among 155 articles of interest and the analyses indicated that, in the clinical environment, the use of both conventional EEG and aEEG is highly recommended, as the combination of their functions allows, for example, a greater number of subclinical seizures to be detected. Conversely, the use of a geodesic sensor net EEG could be of great value, as it allows a large amount of data to be analyzed. CONCLUSION: This analysis may be useful in studies and research related to diseases and symptoms, such as seizures, a current challenge for neonatal neuromonitoring, as well as aspects of neurological development and functional studies. However, despite many advances in technology, electroencephalography in preterm neonates remains a challenge worldwide and still requires more robust research and efforts towards the best clinical assistance in this extremely early stage of life.

RESUMO Métodos para avaliar a atividade cortical em neonatos têm grande importância na Medicina moderna, pois permitem a observação e avaliação de diversos aspectos clínicos, garantindo que a equipe de saúde tenha conhecimento sobre possíveis medidas de intervenção que possam ser necessárias no tratamento de recém-nascidos. Objetivo: Esta revisão sistemática tem como objetivo comparar as principais tecnologias disponíveis para a avaliação das funções cerebrais em neonatos: eletroencefalograma convencional (EEG), eletroencefalograma de amplitude integrada (aEEG) e eletroencefalograma da rede do sensor geodésico. Métodos: Os artigos foram selecionados em periódicos nacionais e internacionais, incluídos nas bases de dados eletrônicas Web of Science, LILACS, SciELO e Medline. Resultados: Foram encontrados 39 artigos de interesse entre 155 artigos. As análises indicaram que, em relação ao ambiente clínico, o uso associativo de EEG convencional e aEEG é altamente recomendado, pois permite a combinação de funções, facilitando, por exemplo, que um maior número de convulsões sub-clínicas seja detectado. Por outro lado, o uso do eletroencefalograma da rede do sensor geodésico seria de grande valor, uma vez que permite que uma grande quantidade de dados seja analisada. Conclusão: Essa análise pode ser útil em estudos e pesquisas relacionados a doenças e sintomas, como convulsões, um desafio atual para a neuromonitorização neonatal, bem como aspectos de desenvolvimento neurológico e estudos funcionais. No entanto, apesar de muitos avanços tecnológicos, a eletroencefalografia em recém-nascidos prematuros ainda é um desafio em todo o mundo e requer pesquisas e esforços mais robustos para a melhor assistência clínica neste estágio extremamente precoce da vida.

Sleep deprivation, pain and prematurity: a review study.

The aim was to describe current reports in the scientific literature on sleep in the intensive care environment and sleep deprivation associated with painful experiences in premature infant. A systematic search was conducted for studies on sleep, pain, premature birth and care of the newborn. Web of Knowledge, MEDLINE, LILACS, Cochrane Library, PubMed, EMBASE, Scopus, VHL and SciELO databases were consulted. The association between sleep deprivation and pain generates effects that are observed in the brain and the behavioral and physiological activity of preterm infants. Polysomnography in intensive care units and pain management in neonates allow comparison with the first year of life and term infants. We have found few references and evidence that neonatal care programs can influence sleep development and reduce the negative impact of the environment. This evidence is discussed from the perspective of how hospital intervention can improve the development of premature infants.

O objetivo foi descrever o estado atual na literatura científica sobre privação do sono associado a experiências dolorosas no prematuro e o papel na evolução do sono em ambiente de terapia intensiva. Realizou-se uma busca sistemática para estudos sobre sono, dor, prematuridade e programas de atenção ao neonato. Foram consultados as bases Web-of-Knowledge, MEDLINE, LILACS, Biblioteca Cochrane, PubMed, EMBASE, Scopus, BVS e SciELO. A associação entre privação do sono e dor gera efeitos que são observados na atividade cerebral, fisiológica e comportamental dos prematuros. A polissonografia nas unidades intensivas e o manejo da dor em neonatos permitem comparação no primeiro ano de vida com crianças nascidas a termo. Encontraram-se poucas evidências de que programas de cuidado neonatal podem influenciar o desenvolvimento do sono e diminuir o impacto negativo do ambiente. Estas evidências são discutidas na perspectiva de como a intervenção hospitalar pode melhorar o desenvolvimento do prematuro.

Hyper-responsiveness to acute stress, emotional problems and poorer memory in former preterm children.

The prevalence of preterm birth (PTB) is high worldwide, especially in developing countries like Brazil. PTB is marked by a stressful environment in intra- as well as extrauterine life, which can affect neurodevelopment and hormonal and physiological systems and lead to long-term negative outcomes. Nevertheless, little is known about PTB and related outcomes later on in childhood. Thus, the goals of the current study were threefold: (1) comparing cortisol and alpha-amylase (sAA) profiles, including cortisol awakening response (CAR), between preterm and full-term children; (2) evaluating whether preterm children are more responsive to acute stress and (3) assessing their memory skills and emotional and behavioral profiles. Basal cortisol and sAA profiles, including CAR of 30 preterm children, aged 6 to 10 years, were evaluated. Further, we assessed memory functions using the Wide Range Assessment of Memory and Learning, and we screened behavior/emotion using the Strengths and Difficulties Questionnaire. The results of preterm children were compared to an age- and sex-matched control group. One week later, participants were exposed to a standardized laboratory stressor [Trier Social Stress Test for Children (TSST-C)], in which cortisol and sAA were measured at baseline, 1, 10 and 25 min after stressor exposure. Preterm children had higher cortisol concentrations at awakening, a flattened CAR and an exaggerated response to TSST-C compared to full-term children. These alterations were more pronounced in girls. In addition, preterm children were characterized by more emotional problems and poorer memory performance. Our findings illustrate the long-lasting and in part sex-dependent effects of PTB on the hypothalamic-pituitary-adrenal (HPA) axis, internalizing behavior and memory. The findings are in line with the idea that early adversity alters the set-point of the HPA axis, thereby creating a more vulnerable phenotype.

O estudo da percepção de dor no recém-nascido representa um desafio para a pesquisa e a prática médica, particularmente quanto à escolha do método aser utilizado.

The study of pain perception in neonates is still a challenge for medical research and practice in many aspects, especially regarding the choice of research method.

COMFORT behaviour scale and skin conductance activity: what are they really measuring?

AIM: To assess how efficiently the COMFORT behaviour scale measures acute pain in neonates, in comparison with skin conductance activity, a validated measure of pain and stress. METHODS: Images of 36 newborns were analysed before, during and after painful heel pricks to measure glucose levels and compared with skin conductance activity variables. RESULTS: Scale indicators and skin conductance variables were sensitive to changes in the periods 'during-before' and 'during-after' (Wilcoxon's test, p < 0.01). Significant values were found between all scale indicators and number of waves for Kendall's coefficient (p < 0.05), although responses differed when it came to how long they took to increase and correlations varied from fair to moderate (r < 0.6). Facial tension was more closely related to 15 sec after the painful event, while crying and calmness were more closely related to the later intervals (30 and 180 sec). CONCLUSION: All scale indicators were related to skin conductance activity in all periods, indicating pain perception. Facial tension was the most efficient indicator, while others varied in performance after painful events and possibly indicated stress after trauma. These results are discussed from a phenomenological approach and in an anxiety paradigm.

OBJETIVO: Analisar os indicadores do aleitamento materno exclusivo (AME) do Hospital Universitário de Brasília (HUB) nos anos de 1999 e 2008 e identificar fatores associados a sua interrupção precoce MÉTODOS: Estudo retrospectivo transversal com análise de prontuários de crianças atendidas nos anos 1999 e 2008 no Ambulatório de Pediatria, Crescimento e Desenvolvimento do HUB. A duração do AME foi dicotomizada em até quatro meses e quatro meses ou mais, estimando as razões de prevalência para o desmame precoce (AME<4 meses), utilizando-se um modelo de regressão de Poisson com variância robusta e o teste não paramétrico de Mann-Whitney para comparação do tempo de AME nos anos estudados. RESULTADOS: Foi analisado um total de 2.173 pacientes, 1.443 referentes ao ano de 1999 e 730 referentes ao ano de 2008. Observou-se um incremento de 110,7 para 123,6 dias na duração do AME de 2008 em relação a 1999 (p<0,0001). O desmame precoce foi 12,6% maior em mães com até sete anos de estudo do que em mães com 11 ou mais anos de estudo (p<0,05). Os demais fatores analisados não mostraram relação estatística com o desmame precoce. CONCLUSÕES: Assim como o encontrado nas capitais brasileiras e Distrito Federal, verificou-se incremento no que diz respeito à duração do AME, associado positivamente ao nível educacional materno mais elevado. Convém ressaltar, porém, que a duração observada no estudo ainda se encontra abaixo dos 180 dias recomendados pela Organização Mundial de Saúde.

OBJECTIVE: To analyze the indicators of exclusive breastfeeding (EB) in Brasilia's University Hospital (BUH) during a 10-year interval and to verify associated factors to early weaning. METHODS: A retrospective cross-sectional study was conducted by chart review of children attending the Pediatric Clinic during 1999 and 2008. The duration of exclusive breastfeeding was categorized at four months and four months or more. Prevalence ratios for early weaning (EB<4 months) were estimated with a model of Poisson regression and robust variance. Non-parametric Mann-Whitney test was used to compare the exclusive breastfeeding duration in the studied years. RESULTS: Among 2,173 patients, 1,443 in 1999 and 730 in 2008. There was an increase from 110.7 to 123.6 days in the duration of EB. A significant association between maternal education and early weaning was shown, with a 12.6% higher prevalence in mothers with less than eight years of schooling compared to those with 11 or more years. No other associations were found in the study. CONCLUSIONS: Similarly to what was found in Brazilian capitals and Brasilia, there was an increase in the length of exclusive breastfeeding related to mother educational level. Nevertheless, the duration exclusive breastfeeding is still below the threshold of 180 days recommended by the World Health Organization.

OBJETIVO: Analizar los indicadores de lactancia materna exclusiva (LME) del Hospital Universitario de Brasília (HUB) los años de 1999 y 2008 e identificar factores asociados a su interrupción temprana. MÉTODOS: Estudio retrospectivo transversal con análisis de prontuarios de niños atendidos en los años de 1999 y 2008 en el Ambulatorio de Pediatría, Crecimiento y Desarrollo del HUB. La duración del LME fue dicotomizada en hasta cuatro meses y cuatro meses o más, estimando las razones de prevalencia para el desmame precoz (LME<4 meses), utilizando un modelo de regresión de Poisson con variancia robusta y la prueba no paramétrica de Mann-Whitney para comparación del tiempo de LME en los años estudiados. RESULTADOS: Se analizó un total de 2.173 pacientes, siendo 1.443 referentes al año de 1999 y 730 al año de 2008. Se observó un incremento del 110,7 para 123,6 días en la duración del LME de 2008 respecto a 1999 (p<0,0001). El desmame temprano fue el 12,6% superior en madres con hasta siete años de estudio que en madres con 11 o más años de estudio (p<0,05). Los demás factores analizados no mostraron relación estadísticamente significativa con desmame temprano. CONCLUSIONES: Así como encontrado en las capitales brasileñas y Distrito Federal, se verificó incremento en lo que se refiere a la duración del LME, asociado positivamente al nivel educacional materno más elevado. Conviene subrayar, sin embargo, que la duración observada en el estudio todavía es inferior a los 180 días recomendados por la Organización Mundial de Salud.
