Alteraciones citogenéticas en pacientes con diagnóstico de infertilidad en Lima, Perú / Cytogenetic abnormalities in patients with infertility diagnosis in Lima, Peru

INTRODUCCIÓN: La infertilidad es una enfermedad multicausal y el componente genético representa uno de sus principales eventos. Si bien la distribución de la infertilidad puede variar entre poblaciones, las parejas de los países con bajos y medianos ingresos pueden verse más afectadas por la infertilidad, con una proporción de alteraciones citogenéticas aún no esclarecidas. OBJETIVO: Evaluar la frecuencia de alteraciones citogenéticas y su correlación con el número de abortos en pacientes peruanas con diagnóstico de infertilidad. MÉTODO: Se realizó un estudio de corte transversal en 400 pacientes de 18 a 60 años, de ambos sexos, con diagnóstico de infertilidad. Se registraron las características clínicas disponibles durante el examen genético y el análisis citogenético convencional fue con bandeo GTG en muestras de sangre periférica. El análisis de correlación se realizó con la prueba de Spearman. RESULTADOS: Del total, 389 pacientes cumplieron los criterios de inclusión, y de estos, 169 (43,44%) tuvieron reportes de abortos (promedio: 2,25, rango: 1-7). Hallamos una correlación significativa ente el número de abortos y las alteraciones citogenéticas (p < 0,000). Reportamos 25/289 (6,43%) alteraciones cromosómicas, de las que 11/25 (44%) fueron heterocromatinas constitutivas y 6/25 (24%) fueron translocaciones reciprocas. Las alteraciones citogenéticas más frecuentes fueron 16qh+ y 9qh+ (ambas con un 16%), y afectaron a 17 (68%) varones. CONCLUSIONES: Existe una moderada frecuencia de alteraciones citogenéticas en pacientes peruanos con diagnóstico de infertilidad, y las alteraciones más frecuentes fueron heterocromatina constitutivas. Además, evidenciamos una correlación significativa ente el número de abortos y las alteraciones citogenéticas.

INTRODUCTION: Infertility is a multicausal disease and the genetic component represents one of its main events. Although the distribution of infertility may vary between populations, couples in low-and-middle-income countries may be more affected by infertility with a proportion of cytogenetic alterations still unclear. OBJECTIVE: To evaluate the frequency of cytogenetic alterations and their correlation with the number of abortions in Peruvian patients with a diagnosis of infertility. METHOD: A cross-sectional study was carried out in 400 patients between 18 and 60 years-old, of both genders with a diagnosis of infertility. The clinical characteristics available during the genetic examination were recorded and the conventional cytogenetic analysis was with GTG banding in peripheral blood samples. The correlation analysis was performed with the Spearman test. RESULTS: Of the total 389 patients who met the inclusion criteria, of these 169 (43.44%) patients had reports of abortions (mean: 2.25, range: 1-7). We found a significant correlation between the number of abortions and cytogenetic alterations (p < 0.000). We report 25/289 (6.43%) chromosomal alterations, where 11/25 (44%) were constitutive heterochromatin, and 6/25 (24%) were reciprocal translocations. The most frequent cytogenetic alterations were 16qh + and 9qh + (both 16%), and affected 17 (68%) men. CONCLUSIONS: There is a moderate frequency of cytogenetic alterations in Peruvian patients diagnosed with infertility, where the most frequent alterations were constitutive heterochromatin. Furthermore, we evidenced a significant correlation between the number of abortions and cytogenetic alterations.

Una actualización: caracterización epidemiológica de tasa de egresos hospitalarios por aborto espontáneo en el periodo 2018-2021, en Chile / An update: epidemiological characterization of hospital discharge rate due to spontaneous abortion during 2018-2021 term, in Chile

Introducción: El aborto espontáneo (AE) es la interrupción natural del embarazo antes de la viabilidad fetal. El objetivo es comparar la tasa de egresos hospitalarios (TEH) por AE entre los años 2018-2021 en Chile. Materiales y métodos: Se llevó a cabo un estudio observacional y ecológico. Los datos de egresos hospitalarios por AE en Chile entre 2018-2021 (n=18.658) según edad, clasificación y días de estadía hospitalaria se obtuvieron desde el Departamento de Estadísticas e Información de Salud. Se calculó la TEH, y no se requirió comité de ética. Resultados: Del total de egresos por AE, la tasa disminuyó un 16,84% entre 2018-2020. El rango etario de 20-44 años registró la mayor TEH con 131,75/100.000 habitantes. Los AE incompletos sin complicaciones presentaron la mayor cantidad de egresos (10.490). La infección genital y pelviana mostró el mayor promedio de días de estadía hospitalaria entre 2018-2021, con 2,82-3,3 días. Discusión: La TEH por AE disminuyó en los años 2018-2020, posiblemente atribuible a una reducción de los embarazos. La mayor TEH por AE se encuentra entre los 20-44 años, donde la frecuencia de trisomías embrionarias y la fecundidad aumenta. La mayor cantidad de egresos por AE incompleto sin complicaciones podría explicarse por una mayor consulta asistencial. La infección genital y pelviana se asoció a más días de hospitalización debido al tipo de manejo brindado. En conclusión, este estudio, al ser representativo de la realidad nacional, brinda una actualización epidemiológica y caracterización del AE en la población, buscando incentivar futuras investigaciones sobre el impacto del AE en la población chilena.

Introduction: Spontaneous abortion (SA) is the natural termination of pregnancy before fetal viability. The objective is to compare the rate of hospital discharges (RHD) due to SA between the years 2018-2021 in Chile. Material and Methods: Observational, ecological study. The data on hospital discharges due to SA in Chile between 2018-2021 (n=18,658) according to age, classification, and days of hospital stay were obtained from the Department of Statistics and Health Information. RHD was calculated, and no ethics committee was required. Results: Of the total discharges due to SA, the rate decreased by 16.84% between 2018-2020. The age range of 20-44 years registered the highest RHD with 131.75/100,000 populations. Incomplete SA without complications presented the highest number of discharges (10,490). Genital and pelvic infection presented the highest average number of days of hospital stay between 2018-2021 with 2.82-3.3 days. Discussion: The RHD for SA decreased in the years 2018-2020, possibly attributable to a reduction in pregnancies. The highest RHD for SA is found between 20-44 years, where the frequency of embryonic trisomies and fertility increases. The greater number of discharges due to incomplete SA without complications could be explained by greater care consultation. Genital and pelvic infection was associated with more days of hospitalization due to the type of management provided. In conclusion, the present study, being representative of the national reality, provides an epidemiological update and characterization of SA in the population, seeking to encourage future research on the impact of SA in the Chilean population.

The effects of Coronavirus disease-2019 (COVID-19) pandemic on routine antenatal care visits and complications of pregnancy

SUMMARY OBJECTIVE: Routine follow-up of pregnancy is a comprehensive care process starting from planning of pregnancy that involves rational and careful use of medical, psychological, and social support. In this study, our objective was to compare the adherence rate to routine antenatal follow-up program during the COVID-19 pandemic with that of previous years among pregnant women, in an effort to shed light on health policies to be developed similar events in the future. METHODS: This retrospective cross-sectional study was carried out between March 11, 2019, when isolation measures were initiated in the context of precautionary steps taken in Turkey against the COVID-19 pandemic, and June 1, 2020, when the "normalization" was initiated. RESULTS: During the study period in 2020, the proportion of cesarean sections were higher, 61.1%, as compared to previous years (p=0.27). The stillbirths were numerically lower (1.2%, p=0.77), but the rate of spontaneous abortions was significantly higher (19.6%, p=0.009). The number of follow-up visits per pregnancy was lower than in previous years (3.8, p=0.02), although the proportion of patients visiting the outpatient units for regular controls to the overall patient group increased as compared to previous years (52.0%). CONCLUSION: During the flare-up of the COVID-19 pandemic (i.e. between March and June 2020), the rate of obstetric/neonatal morbidity and mortality except spontaneous abortion was not significantly higher as compared to the corresponding period in previous years. However, considering the potential increase in the risk of obstetric complications during a pandemic, specialized management programs targeting basic pregnancy follow-up services should be developed.

Untreated Prior Pulmonary Tuberculosis Adversely Affects Pregnancy Outcomes in Infertile Women Undergoing / 生物医学与环境科学（英文）

Objective@#Prior pulmonary tuberculosis (PTB) on chest X-ray (CXR) was commonly found in infertile patients receiving examinations before @*Method@#We conducted a retrospective cohort study of 14,254 infertile patients who had received IVF-ET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth, clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.@*Results@#The untreated PTB group had significantly lower clinical pregnancy (31.7% @*Conclusions@#Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population.

Experiencia clínica del uso de la ficha SIP/CLAP en mujeres con aborto espontáneo resuelto por vía quirúrgica / Clinical experience of the use of the SIP/CLAP form use in women with spontaneous abortion treated by surgical means

INTRODUCCIÓN Y OBJETIVOS: En Chile, existen datos parcializados en cuanto a la prevalencia de aborto. La población migrante ha generado un cambio en las características de las pacientes en situación de aborto. El objetivo es describir las características demográficas y clínicas de las mujeres con aborto de manejo quirúrgico con y sin complicaciones. MÉTODOS: Estudio Descriptivo Transversal. Se incluyeron mujeres atendidas por aborto, sometidas a método de evacuación y que estuvieran ingresadas al sistema SIP/CLAP. Se compararon mujeres con o sin complicaciones con respecto a diferentes características demográficas y clínicas. Se calculó Odd Ratio para algunas variables de interés. RESULTADOS: Se incluyeron 554 mujeres, un 13% (N= 73) tuvo complicación al ingreso, principalmente hemorrágica (40%). Las características demográficas fueron similares en ambos grupos. Hubo mayor riesgo de complicación en mujeres con abortos previos (OR: 2,4 (IC 1,3-4,5), p =0.00), cuando el diagnóstico de ingreso fue aborto incompleto (OR: 85,3 (IC 25,2-288), p=0,00) y cuando se realizó legrado (OR: 4 (IC 2,5-6,5) p=0,00). La mayoría de las pacientes con complicaciones no planeó el embarazo (OR: 11 (IC 3,4-37,7), p=0,00) y no usó método anticonceptivo en esta gestación. El 70% recibió método anticonceptivo al egreso. CONCLUSIONES: Existen características clínicas asociadas a complicación en mujeres con aborto de manejo quirúrgico en nuestro centro, como diagnóstico de ingreso, embarazo no planificado, aborto previo y tipo de evacuación. Existen limitaciones en cuanto a la cantidad y calidad de información, sin embargo, nuestros resultados permiten conocer el perfil de pacientes atendidas por aborto en nuestro centro.

INTRODUCTION AND OBJECTIVES: In Chile, there are partial data regarding the prevalence of abortion. The migrant population has generated a change in the characteristics of patients in an abortion situation. The objective is to describe the demographic and clinical characteristics of women with surgical abortion with and without complications. METHODS: Transversal Descriptive Study. Women treated for abortion, undergoing evacuation method and who were admitted to the SIP / CLAP system were included. Women with or without complications were compared with respect to different demographic and clinical characteristics. Odd Ratio was calculated for some variables of interest. RESULTS: 554 women were included, 13% (N = 73) had complication at admission, mainly hemorrhagic (40%). Demographic characteristics were similar in both groups. There was an increased risk of complication in women with previous abortions (OR: 2.4 (IC 1.3-4.5), p = 0.00), when the diagnosis of admission was incomplete abortion (OR: 85.3 (IC 25.2- 288), p = 0.00) and when curettage was performed (OR: 4 (IC 2.5-6.5) p = 0.00). The majority of patients with complications did not plan pregnancy (OR: 11 (IC 3.4-37.7), p = 0.00) and did not use a contraceptive method in this pregnancy. 70% received contraceptive method upon discharge. CONCLUSIONS: There are clinical characteristics associated with complications in women with surgical management abortion in our center, such as admission diagnosis, unplanned pregnancy, previous abortion and type of evacuation. There are limitations regarding the quantity and quality of information, however, our results allow us to know the profile of patients treated for abortion in our center.

Factors associated with spontaneous abortion: a systematic review / Fatores associados ao aborto espontâneo: uma revisão sistemática

Abstract Objectives: to compile studies produced regardinggenetic and non-genetic risks factors associated with occurrence of spontaneous abortion. Methods: it talks about a systematic review article, with studies between January of 2008 to November of 2018 according to SciELO, PubMed, Lilacs and BVS. Results: in total, 567 articles were found. After applying the definedeligibility criteria, 44 articles made part of the review, being the majority published on Asia between 2008 and 2011, and 10 articles published on Brazil. Not genetic causes like sociodemographic factors and healthy state were among the most associated conditions of spontaneous abortion. Asiatic continent had predominance about the correlation of spontaneous abortion with factors related to life style like obesity, smoking and labor activities, on the other hand, in the Americas, causes related to sociodemographics factors like low pay and low studies are high-lighted. Conclusions: the risk factors change about the occurrence region, being important to make local studies capable of subsidize the implantation of public politics and to reduce abortions.

Resumo Objetivos: compilar estudos produzidos acerca dos fatores de risco genéticos e não genéticos associados a ocorrência de aborto espontâneo. Métodos: trata-se de um artigo de revisão sistemática, com estudos publicados entre janeiro de 2008 a novembro de 2018 nas bases de dados SciELO, PubMed, Lilacs e BVS. Resultados: um total de 567 artigos foram encontrados. Após aplicação dos critérios de elegibilidade definidos, 44 artigos compuseram a presente revisão com a maioria publicada na Ásia, entre os anos de 2008 a 2011, e 10 artigos publicados no Brasil. Causas não genéticas, como fatores sociodemográficos e estado de saúde, estiveram entre as condições mais associadas ao abortamento espontâneo. No continente asiático houve predominância na correlação do aborto espontâneo com fatores relacionados ao estilo de vida como obesidade, tabagismo e atividades laborais; já nas Américas destacam-se causas relacionadas aos fatores sociodemográficos, como baixa renda e baixa escolaridade. Conclusões: os fatores de risco diferem em relação a região de ocorrência, sendo importante a realização de estudos detalhados para que sejam capazes de subsidiar a implantação de políticas públicas e, assim, minorar a ocorrência de abortos.

Increase of incidence of congenital syphilis in santa catarina state between 2007-2017: temporal trend analysis / Aumento da incidência de sífilis congênita no estado de santa catarina no período de 2007 a 2017: análise da tendência temporal

ABSTRACT Objective: To estimate the incidence of congenital syphilis and temporal trends of the reported cases of the disease in the state of Santa Catarina between 2007 and 2017. Methods: Observational study with retrospective cohort design, with secondary data from the Injury of Notification Information System (SINAN). Linear trend test and geoprocessing were performed to verify the behavior of the cases in the period. Results: There were 2,898 reported cases of congenital syphilis in the period, with an average of 2.9 per 1,000 live births in the period. There was an exponential increase of 0.9 percentage points per year, considered statistically significant (p<0.001). There was no difference between the incidences of cases in the different regions of the State. The fatality rate was 8.5%, considering deaths from syphilis, miscarriages and stillbirths. The profile was predominant of white mothers, with low schooling and 11.8% did not perform prenatal care. For this reason, 26.9% of them had a diagnosis of syphilis at the time of delivery. Most of the pregnant women (51.9%) had inadequate pharmacological treatment and 65.1% of the partners were not treated. Conclusions: There was an exponential increase tendency in cases of congenital syphilis in the State of Santa Catarina in the period studied in all regions of the State, which reveals the failure of prenatal care, late diagnosis and inadequate treatment of the pregnant woman and her partner.

RESUMO Objetivo: Estimar a incidência de sífilis congênita e a tendência temporal dos casos notificados da doença no estado de Santa Catarina no período entre 2007 e 2017. Métodos: Estudo observacional com desenho de coorte retrospectiva, com dados secundários coletados no Sistema de Informação de Agravos de Notificação (SINAN). Foi realizado o teste de tendência linear e o geoprocessamento para verificar o comportamento dos casos no período. Resultados: No período, foram notificados 2.898 casos de sífilis congênita, com média de 2,9 a cada mil nascidos vivos. Houve crescimento exponencial de 0,9 ponto percentual ao ano, sendo estatisticamente significante (p<0,001). Não houve diferença entre a incidência de casos nas diferentes regiões do Estado. A taxa de letalidade foi de 8,5%, considerando os óbitos por sífilis, os abortos e os natimortos. O perfil predominante foi de mães da raça branca e com baixa escolaridade. Do total de mães analisadas, 11,8% não realizaram pré-natal - por esse motivo, 26,9% delas tiveram o diagnóstico de sífilis no momento do parto. A maioria das gestantes (51,9%) teve tratamento farmacológico inadequado e 65,1% dos parceiros não foram tratados. Conclusões: No período estudado, houve tendência de aumento exponencial dos casos de sífilis congênita em todas as regiões do Estado de Santa Catarina, o que revela a falha no pré-natal, o diagnóstico tardio e o tratamento inadequado da gestante e do seu parceiro.

Pregnancy Outcomes in COVID-19: A Prospective Cohort Study in Singapore

INTRODUCTION@#Pregnant women are reported to be at increased risk of severe coronavirus disease 2019 (COVID-19) due to underlying immunosuppression during pregnancy. However, the clinical course of COVID-19 in pregnancy and risk of vertical and horizontal transmission remain relatively unknown. We aim to describe and evaluate outcomes in pregnant women with COVID-19 in Singapore.@*METHODS@#Prospective observational study of 16 pregnant patients admitted for COVID-19 to 4 tertiary hospitals in Singapore. Outcomes included severe disease, pregnancy loss, and vertical and horizontal transmission.@*RESULTS@#Of the 16 patients, 37.5%, 43.8% and 18.7% were infected in the first, second and third trimesters, respectively. Two gravidas aged ≥35 years (12.5%) developed severe pneumonia; one patient (body mass index 32.9kg/m2) required transfer to intensive care. The median duration of acute infection was 19 days; one patient remained reverse transcription polymerase chain reaction (RT-PCR) positive >11 weeks from diagnosis. There were no maternal mortalities. Five pregnancies produced term live-births while 2 spontaneous miscarriages occurred at 11 and 23 weeks. RT-PCR of breast milk and maternal and neonatal samples taken at birth were negative; placenta and cord histology showed non-specific inflammation; and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific immunoglobulins were elevated in paired maternal and umbilical cord blood (n=5).@*CONCLUSION@#The majority of COVID-19 infected pregnant women had mild disease and only 2 women with risk factors (obesity, older age) had severe infection; this represents a slightly higher incidence than observed in age-matched non-pregnant women. Among the women who delivered, there was no definitive evidence of mother-to-child transmission via breast milk or placenta.

Concentração de iodo urinário em urina de 24 horas de gestantes e sua associação com bócio tireoidiano materno, aborto e peso neonatal: estudo piloto / Urinary iodine concentration in 24-hour urine of pregnant women and its association with goiter in the mother, abortion and neonatal weight: pilot study

Introdução: A comida tem um papel proeminente na obtenção do iodo e uma das melhores estratégias é a iodização do sal. No Brasil, a Anvisa reduziu as doses de iodo no sal de cozinha desde 2014. Portanto, é importante avaliar a concentração urinária de iodo (CIU) em nossa população. Com base no exposto, propõe-se avaliar a CIU das gestantes, associando-a à frequência de bócio materno, aborto e peso neonatal. Métodos: Trata-se de um estudo observacional com um corte transversal composto por 37 pacientes atendidos no Serviço de Obstetrícia da Faculdade de Medicina de Barbacena e uma clínica particular em Juiz de Fora. A CIU foi verificada em 24 horas de urina. Resultados: A média de CIU foi de 213,6 µg/l de urina, com dose mínima de 29 µg/l e máxima de 437 µg/l. A glândula tireoide foi avaliada durante o exame clínico prénatal (palpação da glândula) e em 24 pacientes (38,1%) foi considerada normal. A palpação da glândula tireoide foi associada à CIU. Houve maior iodúria em gestantes com glândula não palpável (p = 0,004; T = 14,13). Não houve associação entre a CIU e história de aborto ou peso fetal ao nascimento (p > 0,05). Conclusões: Apesar de ser uma amostra pequena da população, identificamos pacientes expostas ao déficit. No entanto, a CIU não parece estar associada ao peso do recém-nascido ou a abortos, mas à dosagem de TSH e ao tamanho da glândula tireoide. Assim, a palpação da glândula tireoide poderia ser usada como uma medida indireta do CIU. (AU)

Introduction: Food has a prominent role in providing iodine and one of the best strategies is salt iodization. The Brazilian Health Regulatory Agency has reduced iodine content in table salt since 2014. Therefore, there is a need for evaluating urinary iodine concentration in our population, especially after the modified recommendations. Based on the above, we sought to assess urinary iodine concentration in pregnant women, associating it with frequency of maternal goiter, abortion and neonatal weight. Methods: This observational, cross-sectional study included 37 patients seen at the Obstetrics Service of Barbacena Medical School and a private clinic in Juiz de Fora, both in the state of Minas Gerais, Brazil. Iodine concentration was determined in 24- hour urine through chromatography. Results: The mean 24-hour urine iodine was 213.6 µg/l, with minimum and maximum measures of 29 µg/l and 437 µg/l, respectively. The thyroid gland was assessed by prenatal clinical examination (palpation of the gland). In 24 patients (38.1%) it was considered normal. Palpation of the thyroid gland was associated with 24-hour urine iodine concentration, although a higher iodine concentration was identified in pregnant women with non-palpable gland (p = 0.004; T = 14.13). There was no association between 24-hour urine iodine concentration and history of abortion or birth weight (p > 0.05). Conclusions: This study, although based on a small sample of the population, was important to identify that even in areas where iodine is considered sufficient there may be patients exposed to iodine deficit. However, urinary iodine concentration does not appear to be associated with birth weight or abortion frequency but is associated with thyroid-stimulating hormone (TSH) level and thyroid gland size, suggesting that clinical evaluation of the thyroid gland is an important element for predicting urinary iodine concentration. Thus, palpation of the thyroid gland could be used as an indirect measure of urinary iodine concentration. (AU)

Early neonatal mortality and risk factors: a case-control study in Paraná State / Mortalidad neonatal precoz y factores de riesgo: estudio caso-control en Paraná / Mortalidade neonatal precoce e fatores de risco: estudo caso-controle no Paraná

ABSTRACT Objective: to analyze the Early Neonatal Mortality risk factors according to the risk stratification criteria of the Guideline of the Rede Mãe Paranaense Program. Method: a case-control epidemiological study with secondary data from the Mortality and Live Birth Information System in 2014. The crude analysis was performed by the Odds Ratio association measure, followed by the adjusted analysis, considering risk factors as independent variables, and early neonatal death as dependent variable. Results: were considered as maternal risk factors: absence of partner and miscarriages; neonatal: male, low birth weight, prematurity, Apgar less than seven in the fifth minute, presence of congenital anomaly; and care: up to six prenatal appointments. Conclusion: an innovative study of risk factors for early neonatal death from the Guideline's perspective, a technological management tool for maternal and child health, in search of its qualification and greater sensitivity.

Abortion in cases of zika virus congenital infection / Aborto nos casos de infecção congênita pelo vírus Zika

Abstract The emergency in international public health caused by the Zika virus gave rise to the discussion about abortion in cases of congenital Zika virus syndrome (CZS). Therefore, we propose to carry out a bibliographic review on abortion in these cases. Five databases were searched using the following terms: abortion, miscarriage, and zika, with the interposition of the Boolean operator "AND." In the selected literature, we found references to the lack of information concerning the risks and severity of CZS, to the great psychological distress suffered by pregnant women, and to the risk of unsafe abortions as a justification for abortion in cases of CZS. However, it is necessary to have available tests that could diagnose, in the first trimester of pregnancy, that the fetus has been affected by the virus, and that it may have important limitations, in order to subsidize the qualified discussion about abortion in these cases.

Resumo A emergência provocada na saúde pública internacional por causa do vírus Zika trouxe à tona a discussão do aborto em casos de síndrome congênita de Zika. Portanto, propomos a realização de uma revisão bibliográfica sobre o aborto nesses casos. Foram pesquisados cinco bancos de dados utilizando os seguintes termos: aborto, aborto espontâneo, e zika, com interposição do operador booleano "E". Na literatura selecionada, encontramos referências à falta de informações sobre os riscos e a gravidade da síndrome congénita de Zika, bemcomo ao grande sofrimento psicológico de mulheres grávidas e ao risco de aborto inseguro como justificativa para o aborto em casos de síndrome congênita de Zika. No entanto, é necessário ter testes disponíveis que possam diagnosticar, no primeiro trimestre da gravidez, que o feto foi afetada pelo vírus, e que ele pode ter limitações importantes, para subsidiar a discussão qualificada sobre o aborto nesses casos.

Spontaneous and induced abortion trends and determinants in the Northeast semiarid region of Brazil: a transversal series / Tendência de abortos espontâneos e induzidos na região semiárida do Nordeste do Brasil: uma série transversal

Abstract Objectives: this study intends to estimate the rates, associated factors and trends of selfreported abortion rates in the northeast of Brazil. Methods: series of population-based surveys realized in Ceará, northeast of Brazil, one of the poorest states in the country. A sample of about 27,000 women of reproductive age was used. Abortion was assessed according to women´s information and rates were calculated using official population estimates. The trends and the association among socioeconomic and reproductive factors were studied using regressive models. Results: a trend for reduction in rates was identified. For induced abortion, the determinants were: not having a partner, condom in the last sexual intercourse, first child up to 25years old (AOR= 5.21; ACI: 2.9 - 9.34) and having less than 13years old at first sexual intercourse (AOR= 5.88; ACI: 3.29 - 10.51). For spontaneous abortion were: having studied less than 8 years, knowledge and use of morning-after pill (AOR= 26.44; ACI: 17.9 - 39.05) and not having any children (AOR= 3.43). Conclusions: rates may have been low due to self-reporting. Young age and knowledge about contraceptive methods were associated to both kinds of abortion, while education level along with spontaneous and marital status with induced. Programs to reduce abortion rates should focus on single younger women with low education.

Resumo Objetivos: este estudo objetiva estimar as taxas, fatores associados e tendência das taxas de aborto no Nordeste do Brasil. Métodos: série de estudos transversais realizada no Ceará, um dos estados mais pobres do país. Uma amostra de cerca de 27000 mulheres em idade reprodutiva foi utilizada. A ocorrência de aborto foi aferida através de informação dada pela participante e taxas foram calculadas usando estimativas populacionais oficiais. As tendências e associações entre fatores socioeconômicos e reprodutivos foram estudadas através de modelos regressivos. Resultados: foi identificada tendência de redução nas taxas de abortamento. Para aborto induzido, os determinantes foram não ter um parceiro fixo, ter utilizado camisinha na última relação sexual, ter tido o primeiro filho com menos de 25 anos (AOR= 5,21; ACI: 2,9 - 9,34), e ter tido a primeira relação com menos de 13 anos (AOR= 5,88; ACI: 3,29 - 10,51). Para o espontâneo, ter estudado menos de oito anos, conhecimento sobre a pílula do dia seguinte (AOR= 26,44; ACI: 17,9 - 39,05), e não ter filhos (AOR= 3,43). Conclusões: as taxas podem ser subestimadas por serem auto relatadas. Estar na adolescência e ter conhecimento sobre métodos contraceptivos foram associados aos dois tipos de aborto, enquanto nível educacional com o espontâneo e estado conjugal com induzido. Programas para reduzir taxas de abortamento deveriam focar em mulheres solteiras e com baixa educação.

Fatores preditores do abortamento entre jovens com experiência obstétrica / Predictive factors of abortion among teenagers with obstetric experience

RESUMO: Objetivo: Analisar os fatores preditores do abortamento entre jovens com antecedentes gestacionais. Métodos: Estudo seccional realizado com 464 jovens de Teresina, Piauí, que finalizaram uma gravidez no primeiro quadrimestre de 2006 em seis maternidades do município, com faixa etária entre 15 e 19 anos. Os dados foram coletados de maio a dezembro de 2008, no domicílio das jovens após sua identificação nos registros das maternidades. Para a análise univariada dos dados, utilizou-se a estatística descritiva, e para a análise bivariada empregou-se o teste do χ2 de Pearson e o teste Z. A análise multivariada se deu por meio da Regressão Logística Múltipla (RLM), sendo empregado um nível de significância de 5%. Resultados: As jovens que tiveram mais de uma gestação foram quase nove vezes mais propensas a abortar quando comparadas àquelas que haviam vivenciado apenas uma gestação (p = 0,002). Além disso, as jovens que referiram ter sido pressionadas pelo parceiro a abortar eram quatro vezes e meia mais propensas a consumar o ato quando comparadas aos casos em que a pressão advinha de parentes e amigos do casal (p = 0,007). Conclusão: As jovens que vivenciaram duas ou mais gestações, e que sofreram pressão do companheiro para abortar, eram mais propensas a praticar o aborto. Assim, faz-se necessário que programas de Planejamento Familiar incluam, com maior profundidade, o público adolescente, com vistas a evitar gestações indesejadas nesta população e, consequentemente, o aborto induzido sob condições precárias.

ABSTRACT: Objective: To analyze the predictive factors of abortion among teenagers with gestational history. Methods: Cross-sectional study carried out with 464 teenagers aged between 15 and 19 years, from Teresina, Piauí, who completed a pregnancy in the first quarter of 2006 in six city maternity hospitals. Data were collected from May to December 2008, at the teenagers' home, after their identification in the hospital records. For the univariate analysis of data, descriptive statistics was used, and for bivariate analysis, Pearson's χ2-test and Z-test were applied. Multivariate analysis was performed by means of the Multiple logistic regression (MLR), with significance level of 5%. Results: Teenagers who had more than one pregnancy were almost nine times more likely to have an abortion when compared to those who had only one pregnancy (p = 0.002). Furthermore, the teenagers who reported being pressured by the partner to have an abortion were four times and a half more likely to do it, when compared to those pressured by relatives and friends (p = 0.007). Conclusion: The teenagers who had two or more pregnancies and were pressured by the partner to have an abortion were more prone to do it. Thus, it is necessary that programs of Family Planning include the teenagers more effectively, aiming at avoiding unwanted pregnancies among this population and, consequently, abortion induced in poor conditions.

Factors Associated with Abortion in Women of Reproductive Age / Fatores associados ao aborto em mulheres em idade reprodutiva

Abstract Purpose To verify sociodemographic factors associated with the occurrence of abortion in women of reproductive age, in areas covered by the Family Health Strategy (FHS), a program from the Brazilian Ministry of Health. Methods A cross-sectional study using household surveys of 350 women aged 15 to 49. The report of abortion was a variable indicator, and sociodemographic aspects were covariables. Prevalence ratio (PR) and respective 95% confidence intervals were used to estimate the magnitude of the associations. Results There were associations among age, civil status, race/color, and religion; an increase in the prevalence of lower levels of education, age less than 20, and student status were protective factors. Conclusion The association between sociodemographic characteristics and the report of abortion is attributed to the fact that there is a lack at the FHS in the availability of fundamental healthcare services for young women; these findings call for action to guarantee the access to information about contraceptives and guidance to decrease the risk of unplanned pregnancies and abortions.

Resumo Objetivo Verificar fatores sociodemográficos associados à ocorrência de aborto em mulheres em idade reprodutiva, em área de cobertura de Estratégia Saúde da Família ( ESF ). Métodos Estudo de corte transversal, por inquérito domiciliar com 350 mulheres de 15 a 49 anos de idade. Relato de aborto constituiu variável indicadora e aspectos sociodemográficos covariáveis. Utilizou-se a razão de prevalência (RP) e respectivos intervalos de confiança a 95% para estimar a magnitude das associações. Resultados Houve associação entre idade, estado civil, raça/cor e religião. Aumento da prevalência na menor escolaridade e ser menor de 20 anos e estudante constituíram fator de proteção. Conclusão A associação entre características sociodemográficas e relato de aborto remete a uma atenção à saúde na ESF sem cumprimento dos fundamentos das políticas para mulheres, e suscita ações que garantam às jovens acesso a informações, contraceptivos e a orientações que diminuam os riscos de gravidez não planejada e de abortos.

Abortion: a review of women's perception in relation to their partner's reactions in two Brazilians cities / Abortamento: avaliação da percepção das mulheres relacionada às reações e às condutas do parceiro em duas cidades brasileiras

Objective: to analyze women's perception in relation to their partner's reaction and behavior during the abortion process in two Brazilian capitals, associating the variables from women who suffered a spontaneous abortion with those from women who induced it. Methods: semi-structured, questionnaire-based interviews were conducted with 285 women who underwent spontaneous abortion and 31 who reported having induced it. The data were analyzed using the thematic analysis technique, and, subsequently, by the IBM SPSS Statistics Standard Edition software program. The significance level was set at p < 0.05. Results: in both capitals, the women who induced an abortion referred to the partner as the person who could not find out about the abortion (p<0.01 in Natal; p = 0.02 in São Paulo-SP) and, simultaneously, as the one who could have avoided it (p < 0.01 in Natal; p = 0.03 in São Paulo). In Natal-RN, induced abortion was associated with the partner's absence at the time pregnancy was confirmed (p = 0.02) and, in Sao Paulo-SP, with their negative reaction to news of the pregnancy (p = 0.04) and lack of participation in the abortion process (p < 0.01). Conclusion: despite having achieved independence, women still regard male participation in the abortion process as an important factor. The specifics of each capital denote the influence of the geographic and cultural dimension, indicating the need to take into account the particulars of each region in Brazil while considering a holistic approach to women's health. .

Objetivo: analisar a percepção das mulheres quanto às reações e às condutas do parceiro no processo do abortamento, associando as variáveis entre mulheres que sofreram abortamento espontâneo e que o provocaram, nas cidades de Natal (RN) e de São Paulo (SP). Métodos: foram realizadas entrevistas semidirigidas com 285 mulheres que sofreram abortamento espontâneo e 31 mulheres que referiram tê-lo provocado. Os dados foram analisados pela Técnica de Análise Temática e, posteriormente, utilizou-se o programa IBM SPSS. O nível de significância utilizado foi p < 0,05. Resultados: em ambas as capitais, as mulheres que provocaram o abortamento referiram o parceiro como alguém que não poderia saber do abortamento (p < 0,01 em Natal; p = 0,02 em São Paulo) e, ao mesmo tempo, como aquele que poderia tê-lo evitado (p < 0,01 em Natal; p = 0,03 em São Paulo). Em Natal, o abortamento provocado foi associado à ausência do parceiro no momento da confirmação da gestação (p = 0,02) e, em São Paulo, a reações negativas quando noticiada a gravidez (p=0,04) e a não participação no processo do abortamento (p < 0,01). Conclusão: apesar da independência feminina conquistada, os resultados obtidos indicam que as mulheres que provocaram o abortamento percebem a participação masculina como importante no processo. As particularidades de cada capital denotam influência da dimensão geográfica e cultural, demonstrando a necessidade de uma assistência integral à saúde da mulher que respeite as especificidades de cada região do Brasil. .

Recurrent spontaneous miscarriage is still a challenging diagnostic and therapeutic quagmire

Recurrent spontaneous miscarriage [RSM], affecting 1-2% of women of reproductive age seeking pregnancy, has been a clinical quagmire and a formidable challenge for the treating physician. There are many areas of controversy in the definition, aetiology, investigations and treatment of RSM. This review will address the many factors involved in the aetiology of RSM which is multifactorial in many patients, with antiphospholipid syndrome [APS] being the most recognized aetiological factor. There is no identifiable cause in about 40-60% of these patients, in which case the condition is classified as idiopathic or unexplained RSM. The RSM investigations are extensive and should be undertaken in dedicated, specialized, well-equipped clinics/centres where services are provided by trained specialists. The challenges faced by the treating physician are even more overwhelming regarding the decision of what should be the most appropriate therapy offered to patients with RSM. Our review will cover the diverse modalities of therapy available including the role of preimplantation genetic testing using recent microarray technology, such as single nucleotide polymorphism and comparative genomic hybridization, as well as preimplantation genetic diagnosis; the greatest emphasis will be on the treatment of APS, and there will be important comments on the management of patients presenting with idiopathic RSM. The controversial areas of the role of natural killer cells in RSM, the varied modalities in the management of idiopathic RSM and the need for better-planned studies will be covered as well

Chromosomal abnormalities in couples with repeated fetal loss: An Indian retrospective study.

BACKGROUND: Recurrent pregnancy loss is a common occurrence and a matter of concern for couples planning the pregnancy. Chromosomal abnormalities, mainly balanced rearrangements, are common in couples with repeated miscarriages. PURPOSE: The purpose of this study is to evaluate the contribution of chromosomal anomalies causing repeated spontaneous miscarriages and provide detailed characterization of a few structurally altered chromosomes. MATERIALS AND METHODS: A retrospective cytogenetic study was carried out on 4859 individuals having a history of recurrent miscarriages. The cases were analyzed using G‑banding and fluorescence in situ hybridization wherever necessary. RESULTS: Chromosomal rearrangements were found in 170 individuals (3.5%). Translocations were seen in 72 (42.35%) cases. Of these, reciprocal translocations constituted 42 (24.70%) cases while Robertsonian translocations were detected in 30 (17.64%) cases. 7 (4.11%) cases were mosaic, 8 (4.70%) had small supernumerary marker chromosomes and 1 (0.6%) had an interstitial microdeletion. Nearly, 78 (1.61%) cases with heteromorphic variants were seen of which inversion of Y chromosome (57.70%) and chromosome 9 pericentromeric variants (32.05%) were predominantly involved. CONCLUSIONS: Chromosomal analysis is an important etiological investigation in couples with repeated miscarriages. Characterization of variants/marker chromosome enable calculation of a more precise recurrent risk in a subsequent pregnancy thereby facilitating genetic counseling and deciding further reproductive options.

Perdas fetais espontâneas e voluntárias no Brasil em 1999-2000: um estudo de fatores associados / Spontaneous and voluntary fetal losses in Brazil in 1999-2000: a study of associated factors

Apesar de ilegal no Brasil, cerca de 31% das gestações terminam em aborto. A maioria dos abortamentos provocados é realizada por pessoas não capacitadas, e em condições inseguras, resultando em aumento da mortalidade feminina. O presente estudo utilizou dados de uma amostra representativa de 3.047 puérperas, de 1999-2000, de corte transversal, parte de estudo multicêntrico nacional sobre soroprevalência de sífilis no Brasil. Destas, foram analisadas 1.838 puérperas com pelo menos uma gravidez anterior à gravidez de referência. Os desfechos estudados foram perdas fetais prévias (voluntária e espontânea) e ausência de perda fetal prévia. A análise foi conduzida por meio de regressão logística multinomial. Os resultados indicaram alto número de perdas fetais por mulher (até seis) e 31% das perdas foram voluntárias. A ausência de pré-natal, a história de DST na gravidez de referência e a ausência de filhos vivos aumentaram a ocorrência de perdas fetais. Para as perdas voluntárias, a raça/cor não branca, mais de um parceiro no ano anterior e idade precoce à primeira relação sexual também concorreram para o aumento da ocorrência. Características de vulnerabilidade destas mulheres devem ser consideradas em programas de planejamento familiar e de aconselhamento de mulheres, focalizando aquelas que já tiveram abortos, para a redução do número e consequências deste procedimento.

Despite its illegality in Brazil, about 31% of all pregnancies end in abortion. Most abortions are performed by unskilled personnel and under unsafe conditions, resulting in increased female mortality. This study used data from a cross-sectional representative sample of 3,047 puerperal women, in 1999-2000, part of a national multicenter study on the prevalence of syphilis in Brazil. Of these, 1,838 women with at least one previous pregnancy before the reference pregnancy were included in the analysis. The outcomes studied were voluntary prior fetal loss, spontaneous prior fetal loss, and no prior fetal loss. The analysis was carried out using multinomial logistic regression. The results indicated a high number of fetal losses per woman (up to six); and 31% of the losses were voluntary. The absence of prenatal care, history of STD in the reference pregnancy, and absence of living children were factors that increased the odds of fetal loss. For voluntary fetal loss, being non-white, having more than one partner in the previous year, and an early age at first sexual intercourse also increased the odds of fetal loss. These data confirm the public health relevance of abortion in Brazil. Characteristics related to women´s vulnerability should be considered in family planning programs in order to reduce the number of abortions and their consequences. Counseling must also be provided, targeting women with a previous abortion.

Aborto provocado em mulheres da periferia da cidade de São Paulo: vivência e aspectos socioeconômicos / Abortion in women living in the outskirts of Sao Paulo: experience and socioeconomic aspects

OBJETIVO: Comparar e analisar aspectos socioeconômicos e emocionais na vivência do aborto provocado e espontâneo em mulheres da periferia da cidade de São Paulo. MÉTODOS: Estudo prospectivo e caso-controle realizado no período de julho de 2008 a março de 2010, envolvendo a realização de entrevistas semidirigidas, previamente elaboradas com mulheres que apresentavam diagnóstico médico de aborto internadas em dois hospitais públicos da periferia da cidade de São Paulo. Foram incluídas 100 mulheres com diagnóstico de aborto que foram internadas para a realização da curetagem uterina. Foram identificadas 11 mulheres que relataram ter provocado aborto (11%) que constituíram o grupo de casos. O grupo controle (n=22) foi selecionado na proporção 2:1, seguindo-se o procedimento: para cada caso de aborto provocado, os próximos dois casos de aborto espontâneo, do mesmo hospital. Foi realizada entrevista semiestruturada com perguntas relativas aos aspectos emocionais, ao contexto familiar, social e econômico. RESULTADOS: As mulheres do grupo com aborto provocado, em relação ao grupo com aborto espontâneo, apresentaram menor escolaridade, sendo mais frequente o nível fundamental (82 versus 36%, p=0,04); menor renda familiar (mediana, R$ 1.000,00 versus R$ 1.400,00, p=0,04); menor renda pessoal (mediana, R$ 200,00 versus R$ 333,00, p=0,04), maior frequência de sentimentos negativos na suspeita (82 versus 22%, p=0,004) e na confirmação (72 versus 22%, p=0,03) da gravidez. CONCLUSÃO: O aborto provocado em mulheres que procuram atendimento em hospitais da periferia da cidade de São Paulo está relacionado a condições socioeconômicas desfavoráveis, o que prejudica a vivência na suspeita e confirmação da gravidez.

PURPOSE: To compare and analyze socioeconomic aspects and the emotional experience of women with spontaneous or induced abortion and in women living in the outskirts of São Paulo. METHODS: A prospective case-control study carried out from July 2008 to March 2010, involving semi-structured interviews with women who presented a previous diagnosis of abortion and who had been admitted to two public hospitals in the outskirts of São Paulo. The study included 100 women with diagnosis of abortion and were hospitalized for curettage. Eleven women who reported induced abortion (11%) represented the case group. The control group (n=22) was selected at a 2:1 ratio according to the following procedure: for every case of induced abortion, the next two cases of spontaneous abortion at the same hospital. A semistructured interview was conducted with questions regarding emotional aspects and family, social and economic context. RESULTS: The women with induced abortion compared to the group with spontaneous abortion had lower educational level, with more frequent elementary level (82 versus 36%, p=0.04), lower income (median, R$ 1,000.00 versus R$ 1,400.00, p=0.04), lower personal income (median, R$ 200.00 versus R$ 333.00, p=0.04), higher frequency of negative feelings upon suspicion (82 versus 22%, p=0.004) and confirmation (72 versus 22%, p=0.03) of pregnancy. CONCLUSION: Among women looking for health care in hospitals in the outskirts of São Paulo, induced abortion is related to unfavorable socioeconomic conditions, which affects the emotional experiences of suspicion and confirmation of pregnancy.
