OBJECTIVES: the objective this study was evaluating the prevalence of maternal colonization by Group B beta-hemolytic Streptococcus (GBS) in pregnant women who delivered preterm and its relationship with adverse maternal/perinatal outcomes.
METHODS: we carried out a retrospective cohort study with singleton pregnancies with or without a culture for GBS (vaginal-rectum) who delivered spontaneously <37 weeks of gestation.
RESULTS: the study included 190 pregnant women, 53.1% (101/190) did not undergo culture for GBS and 46.8% (89/101) have done. Among the patients who had a culture, 13.5% (12/89) had positive culture for GBS and 86.5% (77/89) had a negative culture. Pregnant women without GBS culture had higher prevalence of preterm birth (74.3 vs. 59.6%, p=0.031) and lower prevalence of antibiotic prophylaxis (27.7 vs. 56.2%, p<0.001) than pregnant women with GBS culture. Higher prevalence of crystalline penicillin G use was observed in pregnant women with positive culture compared to pregnant women with negative culture for GBS (100 vs. 39%, p<0.0001). There was no significant association between pregnant women with or without a culture for GBS or positive and negative GBS cultures and adverse maternal/perinatal outcomes.
CONCLUSION: No significant association was found between GBS culture or not, GBS positive or negative culture, adequate or inadequate GBS prophylaxis, and the prevalence of adverse maternal/perinatal outcomes.

OBJECTIVE: to estimate the prevalence of HIV and syphilis, and their association with gestational complications and newborn outcomes in women admitted for delivery at a mother and child center in the South of Brazil.
METHODS: cross-sectional study based on the review of electronic medical records of parturients (March/2016 to June/2018). Sociodemographic and clinical data were analyzed. HIV and syphilis were considered outcomes, then exposures to assess associations with pregnancy and neonatal variables. Prevalence Ratio (PR) were calculated using Poisson Regression with robust variance and 95% Confidence Interval (CI).
RESULTS: data from 6,527 women were evaluated. HIV prevalence was 0.6% and syphilis 1.5%. Women assisted by the public health system [PR=2.28 95%CI=1.07-4.82 for syphilis; PR=3.52 95%CI=1.06-11.72 for HIV] and drug users [PR=5.47 95%CI=2.49-12.04 for syphilis; PR=4.76 95%CI=1.12-20.19 for HIV] were more affected. Syphilis was more prevalent among younger and non-white women (p=0.001). Adequate prenatal care reduced syphilis by 38% (PR= 0.62 95%CI=0.39-0.97; p=0.006). Neonatal complications occurred in 32.3% of syphilis cases and 17.1% of HIV cases. Of the 98 syphilis cases, 29.6% led to congenital syphilis.
CONCLUSION: women in socially vulnerable conditions, such as drug users, were more affected. Congenital syphilis exceeded the national average, reinforcing the need for timely and comprehensive prenatal care.

OBJECTIVES: to develop and validate an educational booklet for pregnant women experiencing pelvic girdle pain.
METHODS: this was a methodological development study conducted at the Federal University of São Carlos, Brazil. The educational booklet was developed following a comprehensive literature review and subsequently validated by healthcare professionals and pregnant women. Content and appearance were assessed using the Content Validity Index (threshold: 0.8 or higher) and the percentage of absolute agreement among participants (threshold: 75% or higher).
RESULTS: in the first stage, healthcare professionals rated the material with a mean global content validity of 0.93. In the second stage, pregnant women indicated an 89.2% agreement regarding its clarity, relevance, and usability. The final version, titled "What You Need to Know About Gestational Pelvic Pain", includes an introduction, the definition and location of pain, its relationship with pregnancy, and practical guidance for prevention and self-management.
CONCLUSION: the educational booklet met the acceptability standards established for validation and may contribute to improving prenatal care and self-management of pelvic girdle pain.

OBJECTIVES: this study aimed to explore, from a maternal perspective, the experiences of Brazilian women regarding prenatal care, childbirth, and immediate postpartum period, including the associated feelings and emotions.
METHODS: a qualitative phenomenological study was conducted with six women, aged 18 years or older, who were in the third trimester of pregnancy during the first part of the study, regardless of parity, and who received care in both public and private healthcare institutions. Semi-structured online interviews were conducted during pregnancy and after birth (30-45 days). Data were analyzed using Interpretative Phenomenological Analysis (IPA).
RESULTS: the findings strongly indicate that perceptions and emotions regarding pregnancy and childbirth varied widely across participants. Common anticipatory feelings included fear, curiosity, and anxiety. Participants who reported negative maternity care experiences expressed feelings of apprehension and stress, whereas positive experiences fostered confidence and peace of mind regarding childbirth.
CONCLUSION: the findings highlight the diverse range of perceptions and emotions during pregnancy, childbirth and immediate postpartum among women in Brazil. The study

OBJECTIVES: to summarize evidence on the quantitative parameters of skin-to-skin contact during hospitalization in newborns ≤32 weeks of gestational age that are associated with infant interactive skills.
METHODS: a systematic review was conducted, consulting databases in August 2024: BVS, Pubmed, CINAHL, Scopus, APA PsycNET, and Web of Science. Eligible studies were those focusing on mother-preterm infant interaction, evaluated by behavioral observation, that performed skin-to-skin contact during hospitalization, and analyzed infant interactive skills. Studies with indirect evaluation or those including children born above 32 weeks of gestational age were excluded. Data extraction and evaluation of methodological quality were performed independently by three reviewers using the QUIPS Tool and Quality Assessment Tool scales.
RESULTS: eight studies were included. The minimum time for the initiation of skin-to-skin contact was found to be 15 minutes of life for stable preterm infants. The duration varied from 1 to 2 hours/day, for approximately 15 days. Skin-to-skin contact was associated with improving contact initiative, responsiveness, reciprocity, gaze, vocalization, positive affect, and the infant's negative mood.
CONCLUSION: skin-to-skin contact needs to be included in the routines of neonatal units, as a tool to promote initial interaction between mother and infant.

OBJECTIVES: to synthesize preventive measures against listeriosis during pregnancy as presented in the scientific literature.
METHODS: a scoping review was conducted following the PRISMA-ScR guidelines. Articles were systematically searched in the PubMed/MEDLINE, SciELO, Web of Science, LILACS, and Scopus databases. Screening and data extraction were performed manually, with the support of the Rayyan^® software.
RESULTS: of 449 articles initially identified, seven were included. The main preventive measures identified were educational interventions on risks and food safety practices, consistent with health authority recommendations. However, the literature also highlights significant challenges in effectively applying these measures, particularly in adapting them to specific social and cultural contexts.
CONCLUSIONS: health education remains the primary strategy for preventing listeriosis during pregnancy. Nevertheless, its effectiveness depends on integrated actions that address sociocultural barriers, regulatory frameworks, and systematic surveillance.

OBJECTIVES: to assess the COVID-19 pandemic impact on breastfeeding rates during birth hospitalization in a Baby-Friendly certified perinatal hospital in Portugal.
METHODS: observational retrospective study comparing pre-pandemic (2019) and pandemic (April-December 2020) periods. A total of 900 healthy term mother-newborn dyads in rooming-in were included. Maternal and neonatal variables associated with breastfeeding at discharge were analyzed using chi-square, Student's t-test, and multivariable logistic regression (p<0.05).
RESULTS: breastfeeding rates were higher in the pandemic period (99.3%) than in the pre-pandemic period (97.6%; p=0.031). Exclusive breastfeeding (80.2% vs. 81.6%; p=0.611) and skin-to-skin contact (56.2% vs. 58.0%; p=0.590) did not differ significantly. Exclusive breastfeeding was associated with vaginal delivery (pre-pandemic OR=3.07; 95%CI=1.83-5.13; p<0.001; pandemic OR=2.29; 95%CI=1.39-3.77; p=0.001), weight loss <10% (p<0.001), and absence of phototherapy in the pre-pandemic period (OR=3.38; 95%CI=1.96-7.12; p<0.001). No associations were found with maternal age, parity, sex, or gestational age.
CONCLUSIONS: exclusive breastfeeding rates were not negatively affected by pandemic restrictions. Maintaining Baby-Friendly practices preserved essential breastfeeding support.

Hypertensive disorders in pregnancy, particularly preeclampsia, represent a global public health issue and are the leading cause of maternal mortality in Brazil, accounting for 20% of maternal deaths. Despite advancements in prevention, disparities persist, especially in low- and middle-income countries, where calcium intake is often below recommended levels. This article reviews the evidence supporting calcium supplementation as an effective strategy for preventing preeclampsia, with benefits extending beyond blood pressure control. Systematic review data from the Cochrane Library highlight a reduction in preeclampsia, maternal morbidity, and preterm birth among women who supplement and have low calcium intake. However, recent debates have questioned the universality of this recommendation, suggesting supplementation only for high-risk pregnancies. These controversies arise from methodological limitations in sensitivity analyses and misinterpretations. Nevertheless, the World Health Organization guidelines advocate calcium supplementation of 1.5-2 g/day for pregnant women in regions with low calcium intake. This recommendation aligns with findings demonstrating improved maternal and neonatal outcomes, emphasizing the need for widespread implementation. Urgent national policies in Brazil are required to ensure equitable access to calcium, particularly given the high prevalence of preeclampsia and maternal mortality.

OBJETIVOS: analisar a tendência e distribuição espacial da hepatite B em gestantes no Brasil.
MÉTODOS: estudo ecológico a partir de todos os casos notificados de hepatite B em gestantes pelo Sistema de Informação de Agravos de Notificação – Sinan entre 2009 e 2018. Foram calculadas as taxas de detecção do vírus da hepatite B (HBV) em todos os municípios. A análise espacial foi realizada por meio do Índice Global de Moran para os dados globais e os indicadores locais de associação espacial (Lisa) para os 5.570 municípios. Para análise de tendências por Estado, utilizou-se o modelo de regressão linear generalizada de Prais-Winsten.
RESULTADOS: foram notificadas 15.253 gestantes com HBV. Observou-se altas taxas de detecção nos municípios de São Miguel da Boa Vista-SC (68,96/1000 Nascidos vivos (NV)), Araguaiana-MT (68,18/1000 NV), Reserva do Cabaçal-MT(80,00/1.000 NV), São Geraldo da Piedade-MG (75/1000 NV), Porto Mauá-RS (111,11/1000 NV), nos respectivos biênios. Moran (I) (I=0,056) apresentou associação espacial positiva. No Lisa observou-se 78 municípios inserido no cluster alto-alto, sendo 51,28%na região Sul e 48 no cluster baixo-baixo com 72,91% no Sudeste. Verificou-se tendência crescente no Maranhão (p=0,004) e Pernambuco (p=0,007) e diminuição no Mato Grosso (p=0,012), Paraná (p=0,031) e Santa Catarina (p=0,008).
CONCLUSÃO: Observou-se a detecção de hepatite B em gestantes na maioria dos municípios brasileiros, com tendência crescente em dois estados e diminuição em outros três.

OBJETIVOS: avaliar a prevalência e os fatores epidemiológicos associados à colonização por Streptococcus do grupo B (GBS) em gestantes na cidade de Porto Velho, Rondônia.
MÉTODOS: GBS foi identificado e isolado por métodos genotípicos e microbiológicos a partir de amostras retovaginais de grávidas com 35-37 semanas de gestação. Os dados epidemiológicos foram coletados através de questionários e sua correlação com a presença de colonização foi avaliada. O perfil de susceptibilidade antimicrobiana foi determinado pelo método de disco-difusão.
RESULTADO: um total de 22.5% (102/453) gestantes foram colonizadas por GBS. Um nível mais alto de colonização foi observado no sítio vaginal (17.6%) em comparação ao sítio retal. Não encontramos nenhum fator sociodemográfico ou obstétrico associado a um risco aumentado de colonização por GBS. Todas as amostras foram suscetíveis aos antibióticos penicilina, ampicilina, cefazolina e ceftriaxona. Em contraste, as taxas de resistência à tetraciclina (74.1%), eritromicina (14.1%) e clindamicina (3.5%) foram observadas.
CONCLUSÕES: a prevalência de GBS, bem como a ausência de preditores de colonização, demonstraram a necessidade de triagem universal para GBS em todas as gestantes da região. Além disso, mostramos que os antimicrobianos de primeira linha recomendados para profilaxia são boas opções para a prevenção da doença GBS neonatal na região.

OBJETIVOS: o presente estudo objetiva realizar uma adaptação transcultural do Wijma Delivery Expectancy/ Experience Questionnaire versão B (WDEQ-B) para o português brasileiro e aplicá-lo numa amostra de puérperas brasileiras, avaliando a prevalência do medo do parto e possíveis fatores associados.
MÉTODOS: realizou-se um estudo transversal envolvendo um processo de tradução e retrotradução do instrumento seguido de uma fase de pré-teste.
RESULTADOS: foi realizada uma adaptação transcultural do WDEQ-B, com correspondência razoável com o instrumento original e amplamente compreensível pelas mulheres brasileiras. Foram incluídas 57 puérperas, em três maternidades públicas, encontrando-se uma prevalência de 10,6%. Além disso, analisando-se a relação entre medo do parto e discordância entre preferência de via de parto e parto atual, foi encontrada uma razão de prevalência de 10,8 (IC95%= 1,3 – 87,7, p=0,026).
CONCLUSÃO: o WDEQ-B foi adaptado com sucesso para o português brasileiro e se mostrou um instrumento de pesquisa linguisticamente e culturalmente compreensível para analisar o medo do parto. Além disso, o estudo mostrou que discordância entre preferência de via de parto e parto atual parece estar associada à maior ocorrência de medo severo do parto.
