Duración de la diarrea aguda infecciosa con el uso de leche deslactosada vs leche con lactosa en la población pediátrica: Revisión sistemática / Duration of acute infectious diarrhea with the use of lactose-free milk vs. lactose-containing milk in the pediatric population: A systematic review

Introducción: La diarrea aguda es una entidad frecuente en pediatría, constituyendo una de las principales causas de mortalidad en países en desarrollo y en niños menores de cinco años. Si bien la alimentación representa uno de los pilares fundamentales en el tratamiento de la misma, no existe consenso entre los profesionales en cuanto a la indicación de leche deslactosada durante el curso del cuadro. Objetivos: Realizar una revisión sistemática para estudiar el impacto del consumo de leche deslactosada vs leche regular en la duración de la diarrea aguda infecciosa en niños. Materiales y métodos: Se realizó una revisión sistemática incluyendo artículos publicados desde el año 2008 al 2023, utilizando para la búsqueda las bases de datos PubMed, Lillacs, Cochrane Library y literatura gris. Se incluyeron estudios experimentales, observacionales, revisiones, guías de atención y metaanálisis, realizados en pacientes pediátricos sin patologías de base, cursando cuadro de diarrea aguda infecciosa, que compararan el uso de leche deslactosada frente a leche regular. Resultados: Se seleccionaron doce artículos. En 9 de ellos se constató una disminución en la duración de la diarrea en los pacientes que recibieron leche deslactosada con una diferencia de medias de 18 horas (en un rango entre 4 y 32.6 horas). No se reportaron diferencias estadísticamente significativas en la mortalidad entre el uso de una u otra fórmula láctea. En relación al uso de una u otra fórmula no se objetivaron variaciones en el peso estadísticamente significativas. La necesidad de hospitalización fue similar entre ambos grupos. Solo un artículo analizó la frecuencia o volumen de deposiciones sin encontrar diferencias significativas (AU)

Introduction:Acute diarrhea is frequent in pediatrics, and constitutes one of the main causes of mortality in developing countries and in children under five years of age. Although feeding is one of the fundamental pillars in the treatment of diarrhea, there is no consensus among professionals regarding the indication of lactose-free milk during the course of the symptoms. Objectives: To conduct a systematic review to study the impact of lactose-free milk vs. regular milk consumption on the duration of acute infectious diarrhea in children. Materials and methods: A systematic review was conducted including articles published between 2008 and 2023, using PubMed, Lillacs, Cochrane Library databases, and gray literature for the search. Experimental and observational studies, reviews, care guidelines and meta-analysis were included, conducted in pediatric patients without underlying diseases, with acute infectious diarrhea, comparing the use of lactose-free milk versus regular milk. Results: Twelve articles were selected. Nine of them showed a decrease in the duration of diarrhea in patients who received lactose-free milk with a mean difference of 18 hours (ranging from 4 to 32.6 hours). No statistically significant differences in mortality were reported between the use of one or the other milk formula. Regarding the use of one or the other formula, there were no statistically significant variations in weight. The need for hospital admission was similar between the two groups. Only one article analyzed stool frequency or volume with no significant differences (AU)

Perceptions and feelings of pregnant women undergoing outpatient follow-up for toxoplasmosis

Introduction: Toxoplasmosis persists as a neglected disease and poses a challenge to public health, especially due to the risk of vertical transmission, which can lead to countless biological complications for the newborn and to psychological and emotional repercussions for the mother. Objective: To understand the perceptions and feelings of pregnant women affected by toxoplasmosis undergoing outpatient follow-up. Materials and Methods: A qualitative and exploratory study developed with 12 women with gestational toxoplasmosis undergoing specialized outpatient follow-up in a municipality from the state of Paraná, Brazil. The data were collected through semi-structured individual interviews and subjected to content analysis, supported by descending hierarchical classification. Results: The pregnant women experienced situations ranging from diagnosis and treatment to preventing the disease in the child and family. These experiences generated fear, distress and uncertainty about the disease, which were not adequately addressed during prenatal assistance in primary care. However, the pregnant women emphasized the importance of the multiprofessional team at the secondary level in monitoring and health education. Discussion: Although the pregnant women felt confident about the treatment and its implications for the child's health, discovering the diagnosis impacted their everyday lives and those of their families, especially due to lack of reliable information about toxoplasmosis and to the absence of emotional support at the primary level. Conclusions: There was a temporary scenario of disinformation among these women, who were not properly guided and supported. However, the guidelines offered in secondary health care were essential for improving knowledge and practices in health.

Ocular manifestation of vertical transmission of dengue: case report / Manifestação ocular de transmissão vertical de dengue: relato de caso

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae.

RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais.

Improved efficiency in the management of newborns with infectious risk factors by the sepsis risk calculator and clinical observation

Abstract Objective To evaluate the efficiency of the sepsis risk calculator and the serial clinical observation in the management of late preterm and term newborns with infectious risk factors. Method Single-center, observational, two-phase cohort study comparing the rates of neonates born ≥35 weeks' gestation, ≥2000 g birthweight, and without major congenital anomalies, who were screened and/or received antibiotics for early-onset neonatal sepsis risk at our center during two periods, before (January/2018-June/2019) and after (July/2019-December/2020) the implementation of the sepsis risk calculator. Results A total of 1796 (Period 1) and 1867 (Period 2) patients with infectious risk factors were included. During the second period, tests to rule out sepsis were reduced by 34.0 % (RR, 95 %CI): 0.66 (0.61, 0.71), blood cultures by 13.1 %: 0.87 (0.77, 0.98), hospital admissions by 13.5 %: 0.86 (0.76, 0.98) and antibiotic administration by 45.9 %: 0.54 (0.47, 0.63). Three cases of early-onset neonatal sepsis occurred in the first period and two in the second. Clinical serial evaluation would have detected all true cases. Conclusions The implementation of a sepsis risk calculator in the management of newborns ≥35 weeks GA, ≥2000 g birthweight, without major congenital anomalies, with infectious risk factors is safe and adequate to reduce laboratory tests, blood cultures, hospital admissions, and antibiotics administration. Serial clinical observation, in addition, could be instrumental to achieve or even improve this goal.

Transmissão vertical do HIV na rede de saúde: reflexões bioéticas sobre gênero e cuidado a partir de um caso emblemático / Vertical transmission of HIV in the health network: bioethics reflections on gender and care based on an emblematic case

Resumo Num cenário epidêmico ainda preocupante, a prevenção da Transmissão Vertical (TV) do HIV impõe problemas complexos, devido as vulnerabilidades individual, social e moral das mulheres vivendo com o vírus, somadas às fragilidades da rede de saúde. A partir de um caso emblemático, este estudo buscou compreender os desafios bioéticos do cuidado para a prevenção da TV do HIV no âmbito do Comitê de Porto Alegre/RS. Os eixos analíticos desenvolvidos refletem sobre como a produção do cuidado se articula, por um lado, com discursos e práticas relacionais pautadas no gênero e interseccionadas por raça e classe social e, por outro, com vulnerabilidades programáticas das políticas de saúde. Vislumbrou-se um processo de extrema estigmatização, em que as poucas ofertas para as mulheres cisgênero se dirigiam à regulação reprodutiva e perpetuavam dinâmicas de violência estrutural. Discute-se caminhos para a construção de um cuidado que incorpore a perspectiva decolonial e busque produzir equidade e justiça social ao reconhecer as trajetórias das mulheres.

Abstract In a still worrying epidemic scenario, the prevention of Vertical Transmission (VT) of HIV poses complex problems, due to the individual, social, and moral vulnerabilities of women living with the virus, in addition to the weaknesses of the health network. Based on an emblematic case, this study sought to understand the bioethical challenges of HIV VT prevention in the scope of the Porto Alegre/RS Committee. The analytical categories developed reflect on how the production of care is articulated, on the one hand, with relational discourses and practices based on gender and intersected by race and social class and, on the other, with programmatic vulnerabilities of health policies. A process of extreme stigmatization was revealed, in which the few offers for cisgender women were aimed toward reproductive regulation and perpetuated dynamics of structural violence. We discuss ways of building care that incorporates a decolonial perspective and seeks to produce equity and social justice by recognizing women's trajectories.

Research progress of B lymphocytes in non-infectious uveitis / 国际眼科杂志(Guoji Yanke Zazhi)

Non-infectious uveitis, an autoimmune disease that can cause severe visual impairment, can be difficult to treat. According to the prevailing hypothesis, the immune-mediated imbalance that contributes to non-infectious uveitis is primarily driven by CD4+T cells. However, recent research has shown that B cells also play a significant role in this process, participating in various ways such as antibody production, antigen presentation, and cytokine secretion in both human uveitis and experimental autoimmune uveitis models. Therapies targeting B cells have been used extensively in various autoimmune diseases. Rituximab, a B-cell inhibitor, is effective in treating noninfectious uveitis that is unresponsive to conventional corticosteroid and immunosuppressive therapy. This paper provides an overview of the involvement of B cells in non-infectious uveitis and their potential use in cellular therapies, aiming to further investigate the mechanisms and develop more effective strategies for prevention and treatment.

Establishment and application of a prospective follow-up research method for acute infectious diseases in Shanghai community residents / 上海预防医学

ObjectiveTo present the exploration and application of a prospective follow-up research method for acute infectious disease surveillance based on natural community populations， using COVID-19 infection as an example， and to provide a reference for improving the infectious disease surveillance and early warning system. MethodsA multi-stage probability proportional sampling method was employed to sample residents from all communities of 16 administrative districts in Shanghai， with households as the units. A cohort for acute infectious diseases based on natural community populations was established. The baseline survey was conducted for all cohort subjects， and COVID-19 antigen test kits were distributed. From December 21， 2022 to September 30， 2023， prospective follow-up monitoring of COVID-19 antigen and nucleic acid was carried out on the study subjects on a weekly basis. The baseline characteristics and follow-up information of the cohort subjects were described. ResultsThe cohort for acute infectious diseases included a total of 12 881 subjects， comprising 6 098 males （47.3%） and 6 783 females （52.7%）. The baseline survey revealed that 35.2% （4 540/12 881） of the subjects had a history of COVID-19 infection. During the follow-up period from December 21， 2022 to September 30， 2023， the average incidence density in the cohort was 0.61/person-year， with a higher incidence density in females （0.63/person-year） compared to males （0.59/person-year）. Individuals aged 60 and above （0.64/person-year） and those with underlying health conditions （0.67/person-year） had a higher incidence density. Healthcare workers showed a notably higher incidence density （0.84/person-year） than that in other occupational groups. As of September 30， 2023， a total of 340 subjects in the cohort experienced secondary infections， with a median interval of 170 days between the first and second infections. ConclusionThis study applies cohort study method to acute infectious disease surveillance， providing crucial data support for estimating infection rates and forecasting alerts for acute infectious diseases in the community. This method can be promoted and applied as a new approach for acute infectious disease surveillance.

The influence of growth time on the identification of Bartonella henselae strains by MALDI-TOF mass spectrometry

ABSTRACT Bartonella spp. are bacteria responsible for neglected diseases worldwide. Bartonella henselae is the species most associated with human infections. It is associated with a large spectrum of clinical manifestations and is potentially fatal. The identification of Bartonella spp. is considered a challenge in clinical routine. These bacteria are fastidious, and the time required to isolate them varies from one to six weeks. MALDI-TOF mass spectrometry has emerged as an application for research on Bartonella spp. , and has still been little explored. We investigated whether three different B. henselae strains with different growth times—14 and 28 days—could be correctly identified by MALDI-TOF mass spectra fingerprint comparison and matching. We found that the spectra from strains with different growth times do not match each other, leading to misidentification. We suggest creating database entries with multiple spectra from strains with different growth times to increase the chances of accurate identification of Bartonella spp. by MALD-TOF MS.

Infecciones bacterianas durante el primer mes post trasplante hepático. Experiencia de 12 años en un único centro. Montevideo-Uruguay

Introducción: Las infecciones bacterianas en trasplante hepático (TH) son una de las principales causas de morbimortalidad. Objetivo: Caracterizar las complicaciones infecciosas bacterianas en el primer mes postrasplante. Pacientes y Métodos: Estudio retrospectivo entre los años 2009-2020. Resultados: 225 pacientes recibieron un TH. 80 (35,5%) desarrollaron al menos un episodio de infección bacteriana en el primer mes postrasplante hepático. Hubo 105 episodios de infección bacteriana con una incidencia de 46,6%. El foco más frecuente fue el abdominal (48,6%) y el microorganismo predominante fue Klebsiella spp. De los 104 aislamientos, el 57,6% presentaron un perfil MDR/XDR. Los pacientes que desarrollaron una complicación infecciosa presentaron menor sobrevida al alta hospitalaria en comparación con los que no la presentaron 87,5 versus 94,5% [OR 4,18 (IC 95%: 1,5-11,6)]. En el análisis multivariado la reintervención quirúrgica precoz [OR 4,286 (IC 95%: 1,911-9,61)], mostró un riesgo significativo de desarrollar una complicación infecciosa bacteriana en el primer mes postrasplante. Conclusiones: Tres de cada 10 pacientes presentaron una infección bacteriana en el primer mes postrasplante con una alta incidencia de bacilos gramnegativos MDR/XDR. Los pacientes que desarrollaron una complicación infecciosa presentaron una menor sobrevida al alta. La reintervención quirúrgica precoz se identificó como un factor predisponente de infección temprana.

Background: Bacterial infections are one of the main causes of morbidity and mortality in liver transplant recipients (LT). Aim: To characterize bacterial infectious complications in the first month an after a liver transplant. Methods: Retrospective analysis of a cohort of liver transplant recipients who presented at least one bacterial infectious complication in the first month after transplant between 2009 and 2020. Results: 225 patients were analyzed. 80 (35.5%) had a least one documented bacterial infection during the first month after transplant. 105 bacterial infections were documented, with an incidence of 46.6%. The most frequent origin was intra-abdominal (48.6%) and the predominant isolated microorganism was Klebsiella spp. Among 104 isolated microorganisms 57.6% showed MDR/XDR profile. Patients who developed a bacterial infectious complication had a shorter overall survival (OS) after discharge from hospital (87.5% vs 94.5%) [OR 4.18 (IC 95%: 1.5-11,6)]. When multivariate analysis of predisposing factors was performed early surgical reoperation was the only variable associated with an increased risk of developing a bacterial complication in the first month [OR 4.286 (IC 95%: 1.911-9.61)]. Conclusions: Three out of 10 patients developed a bacterial infectious complication during the first month after liver transplant with a high incidence of gram-negative bacillus MDR/XDR. Patients who presented infectious complications had a shorter OS after discharge, and early reoperation was identified as a predisposing factor of early infectious complications.

Los controles se tomaron de pacientes embarazadas que estuvieran ingresadas en igual período de tiempo pero que resultaron negativas para las pruebas de SARS-CoV-2. Se incluyeron dos controles por cada caso. Las variables maternas consideradas fueron: trabajo de parto prematuro, diabetes gestacional, estado hipertensivo del embarazo, preeclampsia (severa o no severa), muerte fetal, restricción del crecimiento fetal, abruptio placentae. Las variables neonatales consideradas fueron: estado vital, peso del recién nacido (RN), Apgar al minuto y a los cinco minutos, necesidad de ingreso a una unidad especializada en cuidados neonatales y días de estadía. Se registraron las pruebas para COVID-19 y la condición del RN al alta. Resultados: las características demográficas maternas fueron comparables en ambos grupos. Se observaron 21 (55%) complicaciones obstétricas en el grupo casos y 117 (44,7%) en el grupo controles; OR = 4,2 (IC 95%: 1,9-9,7). Se identificaron 12 (30,8%) complicaciones neonatales en el grupo casos y 3 (3,8%) en el grupo control; OR = 11,2 (IC 95%: 2,9-42,9). El grupo casos estuvo asociado con una menor probabilidad de estar vacunados; OR = 0,3 (IC 95%: 0,13-0,75). Conclusiones: reportamos un riesgo aumentado de resultados maternos y neonatales adversos relacionados con la infección por el virus SARS-CoV-2. La vacunación confirma ser una herramienta valiosa contra esta infección viral.

Introduction: Viral infections during pregnancy can lead to maternal and fetal complications. It is important to describe the maternal and fetal implications of COVID-19 disease. Objetives: To describe and analyze the characteristics of patients who experienced SARS-CoV-2 infection during gestation, and maternal and fetal outcomes. Method: A case-control study was conducted. All pregnant patients who presented SARS-CoV-2 infection and were hospitalized in a private healthcare institution (cases) during the period 1/03/2021 - 31/07/2021 were included in the study. Controls were selected from pregnant patients who were admitted during the same time but tested negative for SARS-CoV-2. Two controls were included for each case. The maternal variables considered were preterm labor, gestational diabetes, preeclampsia, (severe or non-severe) preeclampsia, fetal death, fetal growth restriction, placental abruption. The neonatal variables considered were vital status, newborn weight, one-minute and five-minute Apgar scores, need for admission to a specialized neonatal care unit, and length of stay in days. COVID-19 tests for the newborn and their condition at discharge were recorded. Results: Maternal demographic characteristics were comparable in both groups. Twenty-one (55%) obstetric complications were observed in the case group, and 117 (44.7%) in the control group; OR= 4.2 (95% CI: 1.9-9.7). Twenty-one (30.8%) neonatal complications were observed in the case group, and 3 (3.8%) in the control group; OR= 11.2 (95% CI: 2.9-42.9). The case group was associated with a lower likelihood of being vaccinated; OR = 0.3 (95% CI: 0.13-0.75). Conclusions: We report an increased risk of adverse maternal and neonatal outcomes associated with SARS-CoV-2 virus infection. Vaccination proves to be a valuable tool against this viral infection.

Introdução: as infecções virais durante a gravidez podem causar complicações maternas e fetais. É importante descrever as repercussões maternas e fetais da COVID-19. Objetivos: descrever e analisar as características das pacientes que apresentaram infecção por SARS-CoV-2 durante a gravidez e os desfechos maternos e fetais. Material e métodos: foi realizado um estudo caso-controle. Foram incluídas todas as gestantes que apresentaram infecção por SARS-CoV-2 e que estiveram internadas em instituição privada (casos) no período de 01 de março a 31 de julho de 2021. Os controles foram pacientes grávidas hospitalizadas durante o mesmo período de tempo, mas com teste negativo para SARS-CoV-2. Dois controles foram incluídos para cada caso. As variáveis maternas consideradas foram: trabalho de parto prematuro, diabetes gestacional, estado hipertensivo da gravidez, pré-eclâmpsia (grave ou não grave), óbito fetal, restrição do crescimento fetal, descolamento prematuro da placenta. As variáveis neonatais consideradas foram: estado vital, peso do recém-nascido (RN), Apgar de um e cinco minutos, necessidade de internação em unidade especializada em cuidados neonatais e dias de internação. Os resultados dos testes para COVID-19 e a condição do recém-nascido na alta foram registrados. Resultados: As características demográficas maternas foram comparáveis em ambos os grupos. 21 (55%) complicações obstétricas foram observadas no grupo caso e 117 (44,7%) no grupo controle; OR= 4,2 (IC 95%: 1,9-9,7). 12 (30,8%) complicações neonatais foram identificadas no grupo caso e 3 (3,8%) no grupo controle; OR = 11,2 (IC 95%: 2,9-42,9). O grupo de casos foi associado a uma menor probabilidade de ser vacinado; OR = 0,3 (IC 95%: 0,13-0,75). Conclusões: Relatamos um risco aumentado de resultados maternos e neonatais adversos relacionados à infecção pelo vírus SARS-CoV-2. A vacinação confirma ser uma ferramenta valiosa contra esta infecção viral.

Long-term outcomes of therapeutic corneal transplants performed in a tertiary eye care hospital in South India

Purpose: This study aimed to review the demographics, clinical characteristics, and long?term outcomes of therapeutic penetrating keratoplasty (TPK) performed in a tertiary eye care hospital. Methods: Case records of 149 therapeutic transplants (135 patients) that were performed during the calendar year 2016 were retrospectively analyzed, and outcomes were measured until 3 years of follow?up. Information on demographics, presentation characteristics, keratoplasty indications, offending microbe, and secondary surgical interventions was studied. The final outcome was classified in terms of therapeutic, anatomical, and functional outcomes. Results: The median age of the recipients was 55 years with 61% men. The most common indications for TPK were perforated infectious ulcer (45.9%), nonhealing ulcers (29.9%), and graft infections (17.4%). Fungal etiology was noted in 61.2% and bacterial etiology in 17.4% of the eyes. Therapeutic success was achieved in 130 eyes (89%) at the end of 1 month. Anatomical success was achieved in 130 (98.5%) and 88 patients (86.3%) at the end of 1 and 6 months, respectively. At the 6?month time point, 78 patients (76.5%) attained functional success with vision better than light perception. Three?year follow?up data were available for 23.7% of recipients, of which only 12 patients (37.5%) retained a clear graft either after a primary therapeutic or secondary optical keratoplasty. Conclusion: Therapeutic keratoplasty is highly effective in eradicating infection and providing anatomical integrity. However, timely intervention can aid in achieving the best functional outcome.

Mpox: Aspectos epidemiológicos, imunopatogênicos e manejo pré e pós-infecção / Mpox: Epidemiological, immunopathogenic aspects and pre- and post-infection management

Mpoxou Varíola M é uma zoonose causada por vírus do gênero Orthopoxvirus, causadores também da varíola comum. É uma doença considerada rara e autolimitada, sendo endêmica em países africanos. Entretanto, no ano de 2022 ganhou destaque devido ao surto global que se iniciou, quando o mundo ainda se recuperava da pandemia da COVID-19. Dessa forma, por se tratar de uma doença emergente, a presente revisão visa pontuar aspectos gerais do que se sabe até o momento sobre a Mpox, desde sua imunopatogenia até as formas atuais de prevenção e cuidados pós-infecção

Mpox or Variola M is a zoonosis caused by viruses of the genus Orthopoxvirus, which also cause smallpox. It is a disease considered rare and self-limiting, being endemic in African countries. However, in 2022, it gained prominence due to the global outbreak that began when the world was still recovering from the COVID-19 pandemic. Thus, as it is an emerging disease, this review aims to point out general aspects of what is known so far about Mpox, from its immunopathogenesis to current forms of prevention and post-infection care

Caracterização e geoespacialização da sífilis gestacional e congênita no Paraná, Brasil, 2012-2020 / Characterization and geospacialization of gestational and congenital syphilis in Paraná, Brazil, 2012-2020 / Caracterización y geoespacialización de sífilis gestacional y congénita en Paraná, Brasil, 2012-2020

A sífilis persiste como um problema de saúde pública, sobretudo pelos entraves existentes no enfrentamento da sífilis gestacional e congênita. Considerando que a ocorrência dessas infecções se relaciona a fatores maternos e programáticos, este estudo buscou analisar as características epidemiológicas do binômio mãe-filho exposto à sífilis e sua distribuição espacial no Paraná entre 2012 e 2020. Trata-se de estudo descritivo e ecológico, com dados dos sistemas nacionais de informação do Brasil. Foram considerados os casos de gestantes e de crianças registrados entre 2012 e 2020 no estado do Paraná. Foram apresentadas as frequências absolutas e relativas para a caracterização, calculando-se a variação percentual entre o primeiro e o último triênio. Ainda, foi empregado o índice de Moran para a geoespacialização segundo regiões de saúde. Houve predomínio em mulheres de 20 a 39 anos (71,24%), brancas (67,22%) e com até oito anos de estudo (80,76%), com diagnóstico nas fases primária e latente (76,42%). Os casos concentraram-se em crianças do sexo masculino (48,72%), diagnosticadas na fase recente (96,42%), e naquelas cujas mães aderiram ao pré-natal (88,88%), mas os parceiros, por sua vez, não foram tratados (69,46%). Houve aumento do diagnóstico materno durante o pré-natal (16,61%) e redução dos óbitos infantis por sífilis (31,25%). Observou-se concentração das notificações nas regiões Metropolitana e de Pato Branco. Em suma, as gestantes apresentaram idade reprodutiva e baixa escolaridade e foram tratadas durante o pré-natal, contudo, sem a inclusão dos parceiros. Ademais, evidenciou-se comportamento espacial aleatório nas regiões de saúde, com disparidade entre a sífilis gestacional e a congênita.

Syphilis remains as serious public health issue due to existing obstacles in combating gestational and congenital syphilis. Since the onset of these infections is related to maternal and programmatic factors, this study analyzed the epidemiological profile of the mother-child binomial exposed to syphilis and its spatial distribution in Paraná from 2012 to 2020. This is a descriptive, ecological study with data from Brazilian national information systems. Cases of pregnant women and children recorded between 2012 and 2020 in the state of Paraná were considered. Absolute and relative frequencies were estimated for characterization, calculating the percentage variation between the first and last three years. The Moran index was also used for geospacialization according to health regions. Most women were aged 20 to 39 years (71.24%), white (67.22%), and had up to 8 years of schooling (80.76%), with diagnosis in the primary and latent stages (76.42%). Most cases concerned male children (48.72%), diagnosed in the recent phase (96.42%), and from mothers who adhered to prenatal care (88.88%), but the partners were untreated (69.46%). Maternal diagnosis increased during prenatal care (16.61%) and infant deaths by syphilis decreased (31.25%). Most cases were notified in the Metropolitan and Pato Branco regions. In short, the pregnant women were of reproductive age, had low education, and were treated during prenatal care, but their partners were not included. The health regions showed random spatial behavior, with disparity between gestational and congenital syphilis.

La sífilis persiste como un problema de salud pública, principalmente por los obstáculos en hacer frente la sífilis gestacional y congénita. Teniendo en cuenta que la ocurrencia de estas infecciones está relacionada con los factores maternos y programáticos, este estudio tuvo como objetivo analizar las características epidemiológicas del binomio madre-hijo expuestos a la sífilis y la distribución espacial en Paraná (Brasil) entre 2012 y 2020. Se trata de un estudio descriptivo y ecológico, con datos de los sistemas de información nacionales de Brasil. Se consideraron los casos de mujeres embarazadas y niños registrados entre 2012 y 2020 en Paraná. Se presentaron las frecuencias absolutas y relativas, calculando la variación porcentual entre el primer y el último trienio. Asimismo, se utilizó el índice de Moran, según regiones de salud. Predominaron las mujeres de entre 20 y 39 años de edad (71,24%), blancas (67,22%), con hasta ocho años de estudio (80,76%), con diagnóstico en estadio primario y latente (76,42%). Los casos se concentraron en hijos varones (48,72%), diagnosticados en fase reciente (96,42%), y en aquellos cuyas madres tuvieron acceso a los cuidados prenatales (88,88%), pero su pareja no recibió el tratamiento (69,46%). Hubo un aumento en el diagnóstico materno durante la atención prenatal (16,61%) y una reducción en las muertes de niños por sífilis (31,25%). Se observó una concentración de casos en las regiones Metropolitana y de Pato Branco. En resumen, las mujeres embarazadas se encontraban en edad reproductiva, tenían bajo nivel de estudios y eran atendidas durante el prenatal, sin incluir su pareja. Además, se evidenció un comportamiento espacial aleatorio en las regiones de salud, con disparidad entre sífilis gestacional y congénita.
