BACKGROUND: Limited data exist on the differential risk of HIV acquisition between infants born preterm versus those born at term to women living with HIV (WLHIV). With a reported increase in preterm delivery among pregnant WLHIV, understanding the risk of vertical transmission of HIV in preterm infants can inform strategies to optimise the timing of diagnostic testing, antiretroviral prophylaxis, and infant feeding. OBJECTIVES: To describe the prevalence and timing of HIV acquisition, in utero versus perinatal, among infants with perinatal HIV exposure born prior to 37 weeks completed gestation age compared to those born at term in the Botswana-based Mpepu study and explore predictors of infant HIV acquisition. METHOD: Using data extracted from the Mpepu study, we describe the prevalence, timing and risk factors for HIV acquisition in infants born preterm versus those born at term. Fisher exact testing was used to test for differences in prevalence and timing of HIV and a multivariable logistic regression model was used to assess risk factors for infant HIV acquisition. RESULTS: 2866 infants born to WLHIV were included in this secondary analysis. 532 (19%) were born preterm. There was no observed difference in the prevalence of HIV acquisition among infants born preterm versus at term overall (0.8% vs 0.6%, P = 0.54), at birth (0.2% vs 0.3%, P = 1.00) or between 14 and 34 days post-delivery (0.6% vs 0.3%, P = 0.41). The absence of maternal antiretroviral use during pregnancy significantly predicted infant HIV acquisition, with the risk of HIV acquisition reduced by 96% among infants whose mothers were taking antiretroviral treatment (ART) during pregnancy (adjusted odds ratio: 0.003, confidence interval: 0.01-0.02, P < 0.001. CONCLUSION: There was no observed increase of in utero and peripartum HIV acquisition among infants born preterm following foetal exposure to HIV compared to those born at term.

SUMMARY OBJECTIVE: The aim of this study was to examine the impact of symptom-based screening on the prevalence and outcomes of neonatal coronavirus disease 2019 in pregnant women admitted for delivery. METHODS: A retrospective observational study was conducted from June to August 2020 at Gonzaga Mota of Messejana Hospital, Fortaleza, CE, Brazil. All pregnant women were screened for coronavirus disease 2019 based on symptoms. Reverse transcription-polymerase chain reaction or immunology assays for severe acute respiratory syndrome coronavirus 2 were performed when a patient reported a symptom. All newborns of symptomatic patients were submitted for Reverse transcription-polymerase chain reaction. Newborns were divided into groups according to the Reverse transcription-polymerase chain reaction results to identify the relationship between maternal symptoms and neonatal coronavirus disease 2019. RESULTS: A total of 55 (55/1,026, 5.4%) and 50 (50/1,026, 4.8%) pregnant women reported symptoms and had a positive confirmatory test, respectively. The most common symptom of coronavirus disease 2019 among the pregnant women with positive confirmatory test was cough (n=23, 46%). Seven newborns (7/50, 14%) of symptomatic mothers had positive Reverse transcription-polymerase chain reaction. Upon birth, no newborn had serious complications. CONCLUSION: Universal screening of pregnant women admitted for delivery can reduce the perinatal transmission of coronavirus disease 2019. Symptom-based screening can be an alternative for regions with a low prevalence of the disease where a better allocation of financial resources is necessary.

SUMMARY OBJECTIVE: The objective of this study was to evaluate the correlation between clinical and serological findings of pregnant women and newborns with patterns of histopathologic changes of the placenta diagnosed with coronavirus disease 2019. METHODS: A prospective descriptive study was conducted with pregnant women who were positive for SARS-CoV-2 by reverse transcription polymerase chain reaction or serology (IgG and IgM). Clinical analyses were performed using ELISA to detect anti-SARS-CoV-2 IgG and IgA antibodies using the S1 spike protein domain with the Euroimmun kit. Histopathologic analyses of placentas were performed by two expert pathologists. RESULTS: Maternal SARS-CoV-2 infection was associated with increased neonatal hospital length of stay (p=0.03), increased preterm birth (p=0.04), and Apgar score<7 at 1st min (p=0.00) and 5th min (p=0.02). Pregnant women with positive IgG and/or IgA at delivery had a higher incidence of placental histopathologic changes in addition to a greater likelihood of having an IgG-positive fetus (p<0.0001). Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion changes (p=0.00). CONCLUSION: Maternal SARS-CoV-2 infection was associated with adverse perinatal outcomes. Pregnant women with positive IgG at delivery had a higher incidence of placental histopathologic changes. Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion.

Resumen: Introducción: el SARS-CoV-2 produjo una pandemia afectando la salud de la población mundial desde el año 2019, lo que determinó cambios en las conductas sanitarias. Objetivos: describir resultados obstétricos-neonatales en madres COVID-19 positivas al momento del nacimiento en la asistencia pública y privada en el período desde marzo de 2020 a junio de 2021. Metodología: estudio observacional descriptivo, retrospectivo de las embarazadas COVID-19 positivas al momento del parto y sus neonatos en en el Centro Hospitalario Pereira Rossell y en Médica Uruguaya. Resultados: se obtuvo una muestra de 240 madres y 244 neonatos. El 0,42% (n=1) de las madres presentó sintomatología grave por COVID-19. El 46% (n=110) de los embarazos finalizaron por cesárea. El 3% (n=7) de las madres ingresaron a terapia intensiva, en su mayoría por complicaciones de la gestación. En cuanto a los recién nacidos, tuvieron contacto con su madre el primer día de vida el 86,5% (n=211), siendo la causa principal de ingreso a Terapia Intensiva no contar con cuidador. Se realizó PCR a todos sin identificar transmisión vertical. La internación fue mayor a tres días en 36,48% (n=89). Se registró una sola muerte neonatal por prematurez extrema. Fueron alimentados con pecho exclusivo el 19,67% (n=48) en la internación. Conclusiones: la pandemia afectó la asistencia inicial del binomio madre-hijo. No observamos ascenso en el número de cesáreas pero sí disminución en lactancia exclusiva, prolongación de la estadía hospitalaria y aumento del ingreso en áreas de cuidado intensivo sin detectar contagios en los neonatos.

Summary: Introduction: SARS-CoV-2 virus caused a pandemic that affected the health of the world´s population since 2019, what resulted in changes in health behaviors. Objectives: to describe obstetrical and neonatal results in mothers positive for COVID-19 at the time of birth in public and private institutions between March, 2020 and June, 2021. Method: observational, descriptive, retrospective study of pregnant women positive for COVID-19 at the time of delivery and their neonates at Pereira Rossell Hospital and Medica Uruguaya. Results: a sample of 240 mothers and 244 neonates was studied. 0.42% (n=1) of mothers evidenced severe symptoms for COVID-19. 46% (n=110) of pregnancies ended up in C-sections. 3% of mothers were admitted to ICU due to gestational complications in most cases. As to the newborns, 86.5% of them were in contact with their mother their first day of life, the first cause for their being admitted to ICU was absence of a caregiver. PCR tests were performed to all newborns and no vertical transmission was identified. Hospitalization was longer than three days in 36.48% of cases (n=89). Only one neonatal death was recorded as a consequence of extreme prematurity. Exclusively breastfed babies represented 19.67% (n=48) during hospitalization. Conclusions: the pandemic affected the initial assistance of the mother-child binomial. No increase was observed in the number of C-sections, although exclusive breastfeeding did decrease, hospitalization was longer and there was an increase in admission to the ICU although no neonate contagion was observed.

Resumen: La enfermedad de Chagas (EC) es una patología parasitaria producida por el Tripanosoma cruzi. Constituye, sobre todo su transmisión congénita, un problema de salud pública tanto para territorios endémicos como no endémicos, siendo la principal forma de contagio en Chile. Objetivos: Descri bir un caso de EC congénita y dar a conocer la utilidad del tamizaje prenatal. Caso Clínico: Recién nacida de pretérmino de 29 semanas, hija de madre multípara con antecedente de EC detectado en tamizaje prenatal de embarazo actual. Por el antecedente se realizó PCR de Tripanosoma cruzi a los 4 días de vida que resultó indetectable. A las 6 y 8 semanas de vida, respectivamente, presentó rash máculo eritematoso y cuadro febril asociado a dificultad respiratoria, ambos autolimitados. En fondo de ojo de seguimiento por prematuridad a las 8 semanas de vida, se observaron granulaciones retinales bilaterales por lo que se realizó estudio de TORCH resultando negativo. Simultáneamente a las 8 semanas, por el antecedente materno de EC, se realizó una segunda PCR de Tripanosoma cruzi que resultó positiva. Se informó visualización de tripomastigotes confirmándose el diagnóstico de EC congénita. Se trató con Nifurtimox presentando reacción adversa a los 35 días con neutropenia, regurgitaciones y peso estacionario, por lo que se sustituyó el medicamento por Benznidazol, con lo que completó 60 días de tratamiento. A 22 meses de seguimiento, se mantiene asintomática. Con clusiones: Es necesario aumentar los esfuerzos en la prevención, detección precoz de nuevos casos y estudio de familiares directos, siendo este reporte un ejemplo de la utilidad del tamizaje prenatal para la pesquisa y tratamiento precoz de nuevos casos de EC.

Abstract: Chagas Disease is a pathology caused by the parasite Trypanosoma cruzi. It is considered a public health issue, especially its congenital transmission, not only in endemic countries but also in non endemic ones, being the main form of transmission in Chile. Objectives: To describe a congenital Chagas Disease case and to report about the usefulness of prenatal screening for Chagas Disease. Cli nical Case: A 29-week preterm newborn of a multiparous mother with Chagas Disease detected in the perinatal screening of current pregnancy. Due to history of Trypanosoma cruzi, PCR was performed on the 4th day of life resulting undetectable. At the 6th and the 8th week of life, a macular erythema tous rash and fever and respiratory distress were observed, respectively, both self-limited. At the 8th week of life, as a routine prematurity follow-up, a fundus examination was performed which showed bilateral retinal granulation, therefore, a TORCH study was performed with a negative result. Also, in this same week, a second Trypanosoma cruzi PCR was performed, with a positive result. Lab tests reported visualization of trypomastigotes, confirming the Congenital Chagas Disease diagnosis. The patient was treated with Nifurtimox, presenting an adverse reaction at 35 days of treatment with neu tropenia, vomiting, and poor weight gain. The treating drug was replaced by Benznidazole, achieving 60 days of treatment. At 22 months of chronologic age, the patient has remained asymptomatic. Con clusions: It is necessary to increase efforts in prevention, early detection, and study of direct relatives. This report is an example of the usefulness of Chagas disease prenatal screening for the detection and early treatment of new cases.

Resumen Introducción: se busca cuantificar los retornos de la inversión asociados a una intervención en el sistema público de salud de un municipio de la Provincia de Buenos Aires, Argentina, consistente en el fortalecimiento de la estrategia denominada Eliminación de la Transmisión Maternoinfantil de la Infección por VIH, Sífilis, enfermedad de Chagas Congénita e Infección Perinatal por Hepatitis B (ETMI-PLUS). Metodología: el estudio (cuantitativo) se basa en la metodología de Retorno Social de la Inversión (RSI). Se establecieron definiciones ad-hoc para la medición de los retornos sobre la base de los datos disponibles provenientes de diversas fuentes: información primaria de la Secretaría de Salud del MAB; tasas de transmisión congénita de cada enfermedad notificados al Sistema Nacional de Vigilancia de Salud; presupuestos detallados de los recursos asignados al proyecto por parte de la Fundación Mundo Sano y costos de tratamientos e insumos de nomencladores oficiales. Resultados: por cada peso invertido para reforzar la ETMI-PLUS en el MAB, se obtuvo un retorno de casi 4 pesos, gracias a las mejoras en la eliminación vertical de las cuatro enfermedades y al descenso de las complicaciones cardiacas en las mujeres embarazadas diagnosticadas con chagas y tratadas oportunamente. Conclusiones: estos resultados sugieren la existencia de una relación retorno-inversión favorable, analizada bajo una perspectiva conservadora, ya que, se incluyen exclusivamente los ahorros para el sistema de salud y se excluyen otras dimensiones de los retornos vinculadas con las mejoras en los resultados alcanzados.

Abstract Introduction: we seek to quantify the returns on investment associated with an intervention in the public health system of a Municipality of the Province of Buenos Aires, Argentina. This intervention consists of strengthening the strategy for the Elimination of Mother-to-Child Transmission of HIV Infection, Syphilis, Congenital Chagas Disease and Perinatal Hepatitis B Infection, a strategy called ETMI-PLUS. Methodology: the study (quantitative) is based on the Social Return on Investment (RSI) methodology. Ad-hoc definitions are established for the measurement of returns based on the information available from various sources: primary information from the Ministry of Health of the MAB; rates of congenital transmission of each disease reported to the National Health Surveillance System; detailed budgets of the resources assigned to the project by Fundación Mundo Sano and costs of treatments and supplies from official nomenclators. Results: for each argentinean peso invested in strengthening the ETMI-PLUS in the MAB, a return of almost 4 pesos would have been obtained thanks to the improvements in the vertical elimination of the 4 diseases and the reduction of cardiac complications in pregnant women.Conclusions: these results suggest the existence of a return / investment relationship favorable to the intervention, analyzed under a conservative analysis since savings for the health system are exclusively included and other dimensions of returns associated with improvements in results are excluded.

Abstract Background: SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection is usually mild in children, although it can become severe in some cases. Initially, doubts arose due to vertical perinatal transmission in infected mothers. Therefore, the first recommendations were very restrictive, suggesting mother-newborn separation. This study aimed to describe the clinical behavior of newborns born to mothers with SARS-CoV-2 infection and of children admitted to hospital due to COVID-19 (coronavirus-2 disease). Methods: We conducted a retrospective descriptive study of pediatric patients hospitalized between May 1, 2020, and April 30, 2021 Results: We included 19 patients: 47.4% were neonates born to mothers infected with SARS-CoV-2 (1.63% of deliveries), and 52.6% were pediatric patients aged 2 months to 12 years with confirmed COVID-19 infection (3.43% of all pediatric admissions). All patients presented mild symptomatology and remained isolated with a family member in the room. Vertical transmission was not found, although a positivity rate of 88.89% was detected in fathers Conclusions: Pediatric admissions for COVID-19 did not represent an overload of care. No patient developed complications or required specific treatment. The incidence of COVID-19 deliveries was low, and vertical perinatal transmission was not observed. Admission with a companion facilitated pediatric care, which was favorable for the patient and the healthcare staff.

Resumen Introducción: La infección por SARS-CoV-2 (coronavirus tipo 2 del síndrome respiratorio agudo grave) es habitualmente leve en niños, aunque llega a evolucionar de forma grave en algunos casos. Inicialmente surgieron dudas por la transmisión perinatal vertical en madres infectadas, por lo que las primeras recomendaciones fueron muy restrictivas, ya que sugerían la separación madre-hijo. El objetivo de este estudio fue describir el comportamiento clínico de los recién nacidos de madres con infección por SARS-CoV-2 y de los niños ingresados al hospital por COVID-19 (enfermedad por coronavirus 2) Métodos: Se llevó a cabo un estudio descriptivo retrospectivo de pacientes pediátricos hospitalizados entre el 1 de mayo de 2020 y el 30 de abril de 2021 Resultados: Se incluyeron 19 pacientes: el 47.4% eran neonatos hijos de madres infectadas con SARS-CoV-2 (1.63% de los partos) y el 52.6%, pacientes pediátricos de entre 2 meses y 12 años de edad con COVID-19 (3.43% de los ingresos pediátricos). Todos los pacientes presentaron sintomatología leve y permanecieron aislados en la habitación con un familiar. No se constató la transmisión vertical, aunque se detectó una tasa de positividad en el padre del 88.89% Conclusiones: Los ingresos pediátricos por COVID-19 no supusieron sobrecarga asistencial. Ningún paciente desarrolló complicaciones ni precisó tratamiento específico. La incidencia de partos COVID-19 fue baja y no se constató la transmisión vertical. El ingreso con un acompañante facilitó los cuidados pediátricos, lo que resultó favorable para el paciente y para el personal del servicio.

Resumen Introducción: El SARS-CoV-2 es un Betacoronavirus, así como el SARS-CoV y el MERS-CoV, ambos asociados a abortos espontáneos, parto prematuro, morbi-mortalidad materna y alto número de ingresos a UCI en las gestantes. Además, al ser un virus nuevo, se conoce poco sobre los efectos en la gestación. Esta revisión tiene como objetivo analizar la evidencia disponible sobre el SARS-CoV-2 en la gestación. Materiales y métodos: Se realizó una búsqueda de la literatura en PubMed, ProQuest, Scopus, BVS y SciElo. Se realizó la crítica de la evidencia y la extracción de la información con dos instrumentos propuestos por el Instituto Joanna Briggs. Lo anterior bajo las directrices de PRISMA-ScR. Resultados: Se incluyeron 85 artículos que evidenciaron que la mayoría de gestantes con SARS-CoV-2 desarrollaron enfermedad leve a moderada, pero presentaron mayor riesgo de muerte y complicaciones comparado con las pacientes no embarazadas. Se documentó bajo riesgo de transmisión vertical y los resultados perinatales se asociaron a la severidad del cuadro clínico materno. La efectividad del tratamiento no fue concluyente. Discusión: Se discute la presentación clínica de la infección en las gestantes, la transmisión vertical, el tratamiento, la gravedad de la enfermedad y los desenlaces neonatales. Conclusiones: La COVID-19 en la gestación es una complicación que genera mayor morbimortalidad, por lo que es de vital importancia el desarrollo de más investigaciones que amplíen la comprensión de su comportamiento, las implicaciones fisiológicas, emocionales y el posible tratamiento. Esta revisión hace un análisis riguroso de la calidad de los estudios y aporta información valiosa de la evidencia.

Abstract Introduction: SARS-CoV-2 is a betacoronavirus as well as SARS-CoV and MERS-CoV, both associated with spontaneous miscarriage, preterm birth, maternal morbidity and mortality and a higher number of ICU admissions for pregnant women. Being a new virus, its effects on pregnancy are little known. This review aims to analyze the available evidence on SARS-CoV-2 in pregnancy. Materials and Methods: A literature review was conducted in PubMed, ProQuest, Scopus, BVS and SciElo. Evidence criticism and information extraction were conducted using two instruments from the Joanna Briggs Institute, following the PRISMA-ScR guidelines. Results: 85 articles were included evidencing that most pregnant women with SARS-COV-2 suffered mild to moderate disease and were at a higher risk of death and complications compared to non-pregnant patients. Low risk of vertical transmission was documented and adverse perinatal outcomes were associated with severe maternal clinical manifestations. The effectiveness of treatment was inconclusive. Discussion: Clinical presentation of infection in pregnant women, vertical transmission, treatment, disease severity and neonatal outcomes were discussed. Conclusions: COVID-19 during pregnancy is a complication that generates greater morbidity and mortality, for which it is vital to develop further research on the understanding of the behavior, physiological and emotional implications and possible treatment. This review makes a rigorous analysis of the quality of studies and provides valuable information from evidence.

ABSTRACT Introduction Hepatitis C virus (HCV) can be vertically transmitted from mother to fetus. We evaluated knowledge about HCV vertical transmission in female blood donors who became pregnant following detection of HCV in their donated blood. Methods This was a retrospective descriptive study of females seen at a single blood bank in Sao Paulo, Brazil who were diagnosed with HCV infection in their donated blood. HCV-infected donors who subsequently became pregnant were invited to participate through letters or phone calls. Individuals who agreed to participate were interviewed by questionnaire to evaluate their knowledge on HCV vertical transmission. Results Among 282 HCV-positive female blood donors, 69 reported becoming pregnant after their HCV diagnosis in donated blood. While 24 of these women were successful treated for their infection prior to becoming pregnant, 45 (65.2%) were at risk for vertical HCV transmission either because they had never been treated for HCV, were pregnant before treatment or became pregnant after unsuccessful treatment. Of the 59 women who responded to the question of whether they were informed about the risk of HCV vertical transmission, 58 (98.3%) reported never receiving this information either after obtaining their blood donation results or during their pregnancy. Conclusion The lack of knowledge of HCV-infected women on the possibility for mother-to-child transmission of this virus highlights the critical need to improve communication about pregnancy-related risks between health professionals and HCV-infected women of childbearing age.

Resumen El objetivo del artículo es analizar los imaginarios que se (re) producen en los cursos de preparto de distintas instituciones de la ciudad de La Plata (provincia de Buenos Aires, Argentina), para el periodo comprendido entre el 2013 y el 2019. Siguiendo el esquema de una sociología de la atención médica de embarazos y partos que se basa en la (re) construcción de dos modelos analíticos de atención obstétrica (intervencionista y respetado), se analiza si dichos imaginarios que los cursos producen, abonan a uno u otro modelo o construyen zonas grises. El material empírico se compone de diarios de campo de observaciones con distintos grados de participación en treinta encuentros de seis cursos de preparto distintos; y de registros de entrevistas a mujeres-madres, varones-padres y profesionales de la salud obstétrica. Se analizan los discursos de estos cursos para conocer de qué modos promueven -si lo hacen- el acceso a derechos sexuales y reproductivos y a una atención respetuosa del proceso perinatal o, en otro extremo, si funcionan como dispositivo de transmisión e internalización de normas institucionales y biomédicas. Los cursos de preparto emergen como espacios de encuentro, de intercambio de saberes y experiencias y de (re) producción de imaginarios alrededor de lo normal y lo patológico, lo deseable y lo indeseable, para el tránsito del periodo perinatal, desde la gestación hasta la crianza y el maternaje. Se trata de espacios asistenciales-pedagógicos que adquieren rasgos peculiares según los grupos e instituciones coordinadoras. El desarrollo descriptivo y analítico realizado permitió concluir que en estos espacios se advierten zonas grises, tensiones, expectativas, metodologías y discursos diversos, pero que sigue primando una brecha entre lo que se dice en los cursos y lo que pasa en sala de partos, por la ausencia de líneas de trabajo generales que promuevan la atención obstétrica respetuosa de derechos humanos de las mujeres. Descriptores: autonomización, embarazo, medicina, socialización.

Abstract The objective of the article is to analyze the imaginaries that are (re) produced in the prepartum courses of different institutions in the city of La Plata (province of Buenos Aires, Argentina), for the period 2013-2019. Following the scheme of a sociology of medical care for pregnancies and childbirth that I developed in my doctoral thesis, based on the (re) construction of two analytical models of obstetric care (interventionist and respected), I will analyze whether said imaginary that the courses they produce, pay to one or another model or build gray. The empirical material consists of field diaries of Ig observations with different degrees of participation in 30 meetings of different preparotum courses; and records of interviews with women-mothers, men-fathers, and obstetric health professionals. The discourses of the courses are analyzed to find out in what ways they promote -if they do- access to sexual and reproductive rights and care that is respectful of the perinatal process or, at the other extreme, if they function as a device for the transmission and internalization of institutional and biomedical norms. Prepartum courses emerge as spaces for meeting, exchange of knowledge and experiences and (re) production of imaginaries around the normal and the pathological, the desirable and the undesirable, for the transit of the perinatal period, from pregnancy upbringing and mothering. These are care-pedagogical spaces that acquire peculiar features according to the coordinating groups and institutions. The descriptive and analytical development carried out allowed to conclude that in these spaces there are grays, tensions, expectations, methodologies, and diverse discourses, but that there is a gap between what is said in the courses and what happens in the delivery room, due to the absence of general lines of work that promote obstetric care respectful of women's human rights. Descriptors: autonomization, medicine, pregnancy, socialization.

Resumo O objetivo do artigo é analisar os imaginários que são (re) produzidos nos cursos pré-parto de diferentes instituições da cidade de La Plata (província de Buenos Aires, Argentina), no período entre 2013 e 2019. De acordo com o esquema de uma sociologia da assistência médica à gravidez e ao parto , baseado na (re) construção de dois modelos analíticos de assistência obstétrica (intervencionista e respeitada), analisa-se se esses imaginários, que os cursos produzem, contribuem para um ou outro modelo ou constroem áreas cinzentas. O material empírico consiste em diários de campo de observações com diferentes graus de participação em trinta encontros de seis diferentes cursos pré-parto, bem como registros de entrevistas com mulheres-mães, homens-pais e profissionais de saúde obstétrica. Os discursos dos cursos são analisados para saber de que forma promovem -se o fazem- o acesso aos direitos sexuais e reprodutivos e a cuidados que respeitem o processo perinatal ou, no outro extremo, se funcionam como dispositivo de transmissão e internalização das normas institucionais e biomédicas. Os cursos pré-parto surgem como espaços de encontro, troca de saberes e experiências e (re) produção de imaginários em torno do normal e do patológico, do desejável e do indesejável, para o trânsito do período perinatal, da gravidez para a maternidade. São espaços pedagógico--assistenciais que adquirem características peculiares conforme os grupos e instituições coordenadores. O desenvolvimento descritivo e analítico realizado permitiu concluir que nestes espaços existem zonas cinzentas tensões, expectativas, metodologias e discursos diversos, mas que existe um distanciamento entre o que se fala nos cursos e o que passa na sala de parto, devido à ausência de linhas gerais de trabalho que promovam a assistência obstétrica respeitosa dos direitos humanos da mulher. Descritores: autonomização, gravidez, medicina, socialização.

Abstract: Introduction: Vertical transmission of SARS-CoV-2 from the infected mother to the newborn is still uncertain and the definitive answer is under evaluation. The objective: of this review was to evaluate the evidence available in the literature regarding whether the pregnant woman infected by SARS-CoV-2 represents a potential risk of vertical transmission to the fetus and/or newborn. Material and Method: A scoping review was performed using Science Direct, PubMed, and Cochrane library to search for research papers. Inclusion criteria: published studies of pregnant mothers with COVID-19, with perinatal outcomes reported in the first 72 hours after birth. Results: 569 studies were found; 65 of them were repeated. Therefore, 504 were evaluated, of which 460 were excluded. Finally, 42 research papers that met the inclusion criteria were analyzed. 334 pregnant women with COVID-19 and 335 new borns were described; of which 20 presented SARS-CoV-2 infection confirmed by Polymerase chain reaction (PCR) from nasopharyngeal swab. Of these, 18 were identified in the first 48 hours after birth and 12 presented with symptoms. The most frequent route of delivery was cesarean section in 76.2%, and the gestational age range of the newborns was between 26 and 40 weeks. In 86.8% of the cases, mother-child pairs were isolated. Conclusion: Vertical transmission of COVID-19 is possible, although infrequent. Prospective studies are required to establish the possibility of in utero maternal- fetal transmission and its consequences.

Resumen: Introducción: La transmisión vertical del SARS-CoV-2 de la madre infectada al neonato es una interrogante y la res puesta definitiva está en evaluación. Objetivo: Evaluar la evidencia disponible en la literatura respecto si la embarazada infectada por SARS-CoV-2 significa un riesgo potencial de transmisión vertical para el feto y/o recién nacido. Material y Método: Se realizó una revisión sistemática exploratoria utilizán dose Science Direct, PubMed y Cochrane library para la búsqueda de los trabajos de investigación. Criterios de inclusión: estudios publicados de madres embarazadas con COVID-19 con resultados perinatales informados las primeras 72 horas postnatales. Resultados: Se encontraron 569 estudios; resultando duplicados 65; por lo cual se evaluaron 504, de los cuales se excluyeron 460. Se analiza ron finalmente 42 trabajos de investigación que cumplían criterios de inclusión. Se describen 334 pacientes embarazadas con COVID-19 y 335 recién nacidos, de los cuales 20 presentaron infección por SARS-CoV-2, confirmada por PCR en hisopado nasofaríngeo. De estos, 18 se pesquisaron en las primeras 48 horas postparto y 12 presentaron sintomatología. La vía de parto más frecuente fue la ce sárea en un 76,2%, y el rango de edad gestacional de los recién nacidos fue entre 26 y 40 semanas. En el 86,8% se realizó aislamiento del binomio madre-hijo. Conclusión: La transmisión vertical madre e hijo es posible, aunque infrecuente. Se requieren estudios prospectivos para poder determinar con certeza la posibilidad de la transmisión materno fetal in útero y sus consecuencias.

Abstract In Chile, the COVID-19 pandemic, a disease induced by infection with SARS-CoV-2, has caused more than 25,000 deaths. More than 370,000 women between 15 and 44 years have been detected with the infection. The greater vulnerability of pregnant women has been reported, mainly related to a higher risk for severe or critical COVID-19, with an increased incidence of adverse obstetrics and perinatal outcomes. It is relevant to consider that a high percentage of pregnant women infected with SARS-CoV-2 are asymptomatic for COVID-19, which indicates that specific effects of the virus during pregnancy may not be evident from clinical observation. The presence of SARS-CoV-2 in the placenta has been demonstrated, associating placental infection with vascular alterations that could affect utero-placental flow. On the other hand, vertical transmission to the fetus is rare but feasible. This manuscript summarizes the evidence available to date on the main effects of COVID-19 in pregnancy, emphasizing studies about the impact of SARS-CoV-2 in the placenta. This review aims to promote this issue, highlighting that several questions need to be addressed, considering the effect this pandemic could have on gestational health.

Resumen La crisis sanitaria por la pandemia de COVID-19, enfermedad generada por la infección con el SARS-CoV-2, ha llevado a la pérdida de más de 25,000 vidas en Chile, con más de 370,000 mujeres entre 15 y 44 años con infección confirmada. Se ha reportado una mayor vulnerabilidad de las mujeres gestantes en cuanto a desarrollar cuadros de COVID-19 graves o críticos, con un aumento de la incidencia de resultados obstétricos y perinatales adversos. Es relevante considerar que un alto porcentaje de las gestantes infectadas con SARS-CoV-2 son asintomáticas, lo cual nos pone en alerta en cuanto a que ciertos efectos del virus durante la gestación podrían no ser evidentes para la observación clínica. Se ha demostrado la presencia de SARS-CoV-2 en la placenta, asociándose la infección placentaria con alteraciones vasculares que podrían afectar el flujo útero-placentario. Por otro lado, la transmisión vertical al feto parece que es poco frecuente, pero factible. Se resumen las evidencias disponibles hasta el momento sobre los principales efectos de la COVID-19 en la gestación, con énfasis en los estudios sobre los efectos de la infección por SARS-CoV-2 en la placenta. El objetivo es relevar el tema, destacando que son diversas las preguntas que necesitan ser abordadas, considerando el impacto que esta pandemia podría tener sobre la salud gestacional.

SUMMARY INTRODUCTION: Congenital syphilis is caused by the vertical transmission of bacteria, Treponema pallidum, from nontreated or inappropriately treated pregnant to the fetus. OBJECTIVE: To evaluate the clinical aspects of Congenital syphilis in Brazil, between 2009–2018. METHOD: It is an analytical cross-sectional study whose data were collected from the Department of Chronical Conditions and Sexually Transmitted Infections of Brazilian Health Ministry. Clinical variables were analyzed using the software Joinpoint Regression, which makes a segmented linear regression. RESULTS: In the study period, 156,969 cases of Congenital syphilis and 1642 deaths by this disease were reported. The trend analysis indicates growing in diagnosis of maternal syphilis during prenatal care, appropriate treatment of pregnant, realization of prenatal care, maternal partner treatment, diagnosis of syphilis in children under seven days, and diagnosis of recent syphilis. CONCLUSIONS: Although the trend analysis presents relative improvement in Congenital syphilis panorama in Brazil, the disease still related to high numbers of evitable perinatal morbidity and mortality. Therefore, the prenatal assistance with quality is fundamental to have a possible change in this field in the country.

Abstract: Mental health care has traditionally paid little attention to mothers. Comprehensive perinatal mental health care programs are very scarce in our environment. We propose a framing model that serves for comprehensive perinatal care, including care for the mental processes of reproduction, pregnancy, childbirth, and postpartum from an ecosystemic vision inspired by the proposals of Urie Bronfenbrenner and John Bowlby, among others. The model integrates data from neurobiology and epigenetics and theories from systemic and intergenerational transmission of attachment and trauma. It is embedded in a gender and ecological perspective that allows making visible the mother-baby dyad's needs in the center as a starting point for prevention and attention during the perinatal period. We propose a perinatal view as a model to continue deepening care for mothers and families at the beginning of life, as well as to care for the professionals who care for them. We bet on listening, support and psychotherapy as basic tools in community and individual care for mothers, babies, and families.

Resumen: La atención a la salud mental tradicionalmente ha prestado poca atención a las madres. Son muy escasos en nuestro medio los programas de atención integral a la salud mental perinatal. Proponemos un modelo de encuadre que sirva para la atención integral a la perinatalidad, incluyendo los cuidados a los procesos psíquicos de la reproducción, embarazo, parto y posparto desde una visión ecosistémica inspirada en las propuestas de Urie Bronfenbrenner y John Bowlby, entre otros, integrando las aportaciones de la neurobiología, la epigenética, los modelos de transmisión intergeneracional del apego y el trauma, la sistémica, y añadiendo una perspectiva de género y ecológica que permita visibilizar las necesidades de la díada madre-bebé en el centro como punto de partida para la prevención y la atención en perinatalidad. Proponemos una mirada perinatal como modelo para continuar profundizando en la atención a madres y familias en el inicio de la vida, así como para cuidar también a las profesionales que los atienden. Apostamos por la escucha, el acompañamiento y la psicoterapia como herramientas básicas en la atención comunitaria e individual a madres, bebés y familias.

ABSTRACT The year 2020 has surprised the planet with the covid-19 pandemics. This article is aimed to reflect on the repercussions of the novel coronavirus on maternal and infantile health. Despite of the short time elapsed from the onset of the pandemics, some comorbidities have been described in pregnant women with COVID-19, as well as placental anomalies, spontaneous abortions, stillbirths, maternal deaths, and an increasing number on cesarean section and preterm births. The potential risk will demand a close surveillance of pregnancy behavior in the near future. Moreover, pediatric patients are among 1 and 2% of the population affected by COVID-19, and most of them show mild clinical signs. Nevertheless, about 10% of the children aged less than a year may evolve to severe and critical forms. The multisystem inflammatory syndrome in children has been of special interest, due to its severity and risk for life. In newborns, SARS-CoV-2 infection could be associated to two forms according to the acquisition time: perinatal and postnatal COVID-19. Up to the moment, evidences on vertical transmission are insufficient, but they could not be discarded. In conclusion, as this is an ongoing phenomenon, many questions about the effects of COVID-19 on maternal and infantile health are pending; they will demand a crucial effort by researchers, health providers and decision makers.

RESUMEN El año 2020 ha sorprendido al planeta con la pandemia de la covid-19. Este artículo tiene como objetivo reflexionar sobre las repercusiones del nuevo coronavirus en la salud materno-infantil. Pese al poco tiempo transcurrido desde el inicio de la pandemia, en las embarazadas con covid-19 se han descrito algunas comorbilidades, así como alteraciones placentarias, abortos espontáneos, muertes fetales y maternas, e incremento en los partos por cesárea y nacimientos pretérminos. Los riesgos potenciales demandarán una vigilancia estrecha del comportamiento del embarazo en el futuro inmediato. Por otra parte, del total de la población afectada por la covid-19, los pacientes en edad pediátrica representan entre el 1 y el 2 %, y la mayoría presentan manifestaciones clínicas leves. No obstante, en los menores de un año cerca del 10 % puede evolucionar a formas severas o críticas. De especial interés ha sido la presentación del síndrome inflamatorio multisistémico en niños, debido a su gravedad y riesgo para la vida. En los recién nacidos, la infección por SARS-CoV-2 podría asociarse a dos formas, de acuerdo al momento de adquisición: la covid perinatal y la postnatal. Hasta el momento, las evidencias sobre la existencia de la vía de transmisión vertical son insuficientes, pero no pueden ser descartadas. En conclusión, por tratarse de un fenómeno en desarrollo, aún quedan muchas interrogantes sobre los efectos de la covid-19 en la salud materna e infantil, que demandarán en los próximos meses un gran esfuerzo por parte de investigadores, médicos de asistencia y directivos.
