Effect of subchorionic hematoma on first-trimester maternal serum free ß-hCG and PAPP-A levels.

Objective: This study aimed to investigate the effects of the presence of subchorionic hematoma (SH) in early pregnancies with threatened miscarriage (TM) on levels of first-trimester maternal serum markers, pregnancy-associated plasma protein-A (PAPP-A), and free ß-human chorionic gonadotropin (ß-hCG) levels. Methods: The data of TM cases with SH in the first trimester between 2015 and 2021 were evaluated retrospectively. The data of age and gestational age-matched TM cases without SH were also assessed to constitute a control group. Demographic characteristics, obstetric histories, ultrasonographic findings, and free ß-hCG and PAPP-A levels of the groups were compared. Results: There were 119 cases in the study group and 153 cases in the control group. The median vertical and longitudinal lengths of the SH were 31 mm and 16 mm. The median age of both groups was similar (p=0.422). The MoM value of PAPP-A was 0.088 (.93) in the study group and 0.9 (0.63) in the control group (p=0.519). Similarly, the MoM value of free ß-hCG was 1.04 (0.78) in the study group and 0.99 (0.86) in the control group (p=0.66). No significant relationship was found in the multivariate analysis between free ß-hCG MoM, PAPP-A MoM, age, gravida, and vertical and longitudinal lengths of the hematoma (p>0.05). Conclusion: The level of PAPP-A and free ß-hCG were not affected by the SH. Therefore, these markers can be used reliably in TM cases with SH for the first-trimester fetal aneuploidy screening test.

Perfil dos atendimentos às gestantes com ameaça de abortamento em um hospital universitário do norte Paraná / Profile of care for pregnant women with threat of abortion at a university hospital in Paraná / Perfil de la atención a embarazada con amenaza de aborto en un hospital universitario de Paraná

Objetivo: Descrever o perfil dos atendimentos de gestantes com ameaça de abortamento atendidas em um Pronto Socorro Obstétrico de um Hospital Universitário do Norte do Paraná. Métodos: Pesquisa descritiva, retrospectiva e documental com abordagem quantitativa, desenvolvida com dados obtidos das fichas de classificação de risco obstétrico do Pronto Socorro Obstétrico do Hospital Universitário Regional do Norte do Paraná, referentes aos meses de junho a setembro de 2022. Incluiu-se pacientes gestantes com menos de 20 semanas de gestação e com queixa de sangramento vaginal, chegando-se ao número total de 440 atendimentos. Os dados foram processados, tabulados e submetidos à estatística descritiva através de frequência simples. Resultados: As ameaças de abortamento caracterizaram 16,3% dos atendimentos, predominando pacientes com idade entre 19 e 29 anos, classificações de riscos verde e azul, a maioria provenientes do próprio município e encaminhada via Serviço de Atendimento Móvel de Urgência. Das gestantes atendidas, somente 8,6% precisaram de internação e as demais foram liberadas após consulta. Conclusão: Evidenciou que os atendimentos às gestantes com ameaça de abortamento concentrou-se na faixa etária de 19 a 29 anos, provenientes do próprio município, encaminhadas via Serviço de Atendimento Móvel de Urgência e com classificação de risco na cor verde (pouco urgente), dessa forma, pode-se entender que são casos que em sua maioria poderiam ter sido encaminhados aos seus respectivos hospitais de referência, não sendo necessário o encaminhamento ao hospital referência para o alto risco.

Objective: To describe the profile of care for pregnant women threatened with miscarriage treated in an Obstetric Emergency Room at a University Hospital in Northern Paraná. Methods: Descriptive, retrospective and documentary research with a quantitative approach, developed with data obtained from the obstetric risk classification forms of the Obstetric Emergency Room of the Hospital Universitário Regional do Norte do Paraná, referring to the months of June to September 2022. Patients included pregnant women with less than 20 weeks of gestation and complaining of vaginal bleeding, reaching a total number of 440 consultations. The data was processed, tabulated and subjected to descriptive statistics using simple frequency. Results: Threats of abortion characterized 16.3% of consultations, with a predominance of patients aged between 19 and 29 years, with green and blue risk classifications, the majority coming from the municipality itself and referred via the Mobile Emergency Care Service. Of the pregnant women treated, only 8.6% required hospitalization and the rest were released after consultation. Conclusion: It showed that care for pregnant women with threatened abortion was concentrated in the age group of 19 to 29 years, coming from the municipality itself, sent via the Mobile Emergency Care Service and with a risk classification in green (not very urgent), therefore, it can be understood that most of these cases could have been referred to their respective reference hospitals, with no need to refer them to the high-risk reference hospital.

Objetivo: Describir el perfil de atención a mujeres embarazadas con riesgo de aborto atendidas en una Sala de Emergencia Obstétrica de un Hospital Universitario del Norte de Paraná. Métodos: Investigación descriptiva, retrospectiva y documental con enfoque cuantitativo, desarrollada con datos obtenidos de los formularios de clasificación de riesgo obstétrico del Servicio de Emergencia Obstétrica del Hospital Universitário Regional do Norte do Paraná, referidos a los meses de junio a septiembre de 2022. Pacientes incluidas mujeres embarazadas con menos de 20 semanas de gestación y que refieren sangrado vaginal, alcanzando un total de 440 consultas. Los datos fueron procesados, tabulados y sometidos a estadística descriptiva mediante frecuencia simple. Resultados: Las amenazas de aborto caracterizaron el 16,3% de las consultas, con predominio de pacientes con edades entre 19 y 29 años, con clasificaciones de riesgo verde y azul, la mayoría provenientes del propio municipio y remitidas a través del Servicio Móvil de Atención de Urgencias. De las gestantes atendidas, sólo el 8,6% requirió hospitalización y el resto fue dada de alta tras consulta.

Effect of subchorionic hematoma on first-trimester maternal serum free β-hCG and PAPP-A levels

Abstract Objective This study aimed to investigate the effects of the presence of subchorionic hematoma (SH) in early pregnancies with threatened miscarriage (TM) on levels of first-trimester maternal serum markers, pregnancy-associated plasma protein-A (PAPP-A), and free β-human chorionic gonadotropin (β-hCG) levels. Methods The data of TM cases with SH in the first trimester between 2015 and 2021 were evaluated retrospectively. The data of age and gestational age-matched TM cases without SH were also assessed to constitute a control group. Demographic characteristics, obstetric histories, ultrasonographic findings, and free β-hCG and PAPP-A levels of the groups were compared. Results There were 119 cases in the study group and 153 cases in the control group. The median vertical and longitudinal lengths of the SH were 31 mm and 16 mm. The median age of both groups was similar (p=0.422). The MoM value of PAPP-A was 0.088 (.93) in the study group and 0.9 (0.63) in the control group (p=0.519). Similarly, the MoM value of free β-hCG was 1.04 (0.78) in the study group and 0.99 (0.86) in the control group (p=0.66). No significant relationship was found in the multivariate analysis between free β-hCG MoM, PAPP-A MoM, age, gravida, and vertical and longitudinal lengths of the hematoma (p>0.05). Conclusion The level of PAPP-A and free β-hCG were not affected by the SH. Therefore, these markers can be used reliably in TM cases with SH for the first-trimester fetal aneuploidy screening test.

Malária durante a gravidez: efeito sobre o curso da gestação na região amazônica / Impact of malaria during pregnancy in the Amazon region

OBJETIVO: Estimar o efeito da malária sobre o curso da gestação em mulheres na região amazônica e investigar possíveis fatores de risco nessa população. MÉTODOS: Este estudo transversal é parte de um projeto maior para estudar malária e gravidez na região amazônica. Foram incluídas gestantes com malária atendidas na Fundação de Medicina Tropical do Amazonas que responderam a entrevistas estruturadas. Dados socio-econômicos, comportamentais e clínicos foram levantados na primeira consulta relacionada a cada novo episódio de malária na gestante. Todas as gestantes foram acompanhadas ao longo de sua gestação. Foram considerados os seguintes fatores de risco para alterações no curso da gestação: idade materna menor do que 20 anos, primeira gestação, primeira infecção malárica e espécie de plasmódio infectante. RESULTADOS: Foram avaliados 535 episódios de malária em 417 gestantes, sendo 20,56 por cento causados pelo P. falciparum, 78,69 por cento pelo P. vivax e 0,75 por cento pela associação dos dois parasitas. Alteração no curso da gestação foi um evento muito frequente (26,2 por cento). Ameaça de aborto ocorreu em 49 casos (25,5 por cento), aborto em dois (1,0 por cento), ameaça de parto prematuro em 74 (25,1 por cento) e parto prematuro em três (1,0 por cento). Ser primigesta e adolescente apresentou associação estatisticamente significativa com ameaça de parto prematuro e abortamento. CONCLUSÃO: A alteração no curso da gestação foi um evento muito frequente durante o episódio agudo de malária, embora a interrupção da gestação tenha tido baixa ocorrência em nossa casuística. Os resultados não evidenciaram um fator de risco de destaque, sugerindo que qualquer gestante pode apresentar ameaça de interrupção ou interrupção da gestação na vigência de episódio agudo de malária.

OBJECTIVE: To estimate the impact of malaria on the course of pregnancy in women from the Amazon region and to investigate possible risk factors in this population. METHODS: This cross-sectional study is part of a larger project to study malaria and pregnancy in the Amazon region. Pregnant women with malaria receiving care at the Amazon Tropical Medicine Foundation (Fundação de Medicina Tropical do Amazonas) who answered a structured interview were included in the study. Socioeconomic, behavioral and clinical data were collected in the first consultation relating to each new malaria attack. All the women were followed-up throughout their pregnancy. The following risk factors for impact of malaria on the course of pregnancy were considered: being younger than 20 years of age, first pregnancy, first malaria infection, and type of infecting plasmodium species. RESULTS: Five hundred and thirty-five malaria episodes were evaluated in 417 pregnant women, with 20.56 percent being caused by P. falciparum, 78.69 percent by P. vivax and 0.75 percent by the association of both parasites. Changes in the course of pregnancy were very frequent (26.2 percent). Threat of abortion was observed in 49 cases (25.5 percent), abortion in two (1.0 percent), threat of premature birth in 74 (25.1 percent), and premature birth in three (1.0 percent). First pregnancy and age < 20 years were significantly associated with threat of premature birth and abortion. CONCLUSION: Changes in the course of pregnancy were very frequent during acute malaria attacks, despite the low frequency of abortion. The present results do not highlight specific risk factors, suggesting that any pregnant woman may be at risk for the threat of abortion or for abortion during acute malaria attacks.
