Background Zika virus (ZIKV) infection during pregnancy can cause severe birth defects in the fetus and is associated with neurodevelopmental abnormalities in childhood. Our objective was to describe ZIKV knowledge and attitudes among pregnant women in Colombia while ZIKV was circulating and whether they predicted the adoption of behaviors to prevent ZIKV mosquito-borne and sexual transmission. Methods We used self-reported data from Zika en Embarazadas y Niños (ZEN), a cohort study of women in early pregnancy across three regions of Colombia during 2017–2018. We used Poisson regression to estimate associations between knowledge, attitudes and previous experience with mosquito-borne infection and preventative behaviors. Results Among 1519 women, knowledge of mosquito-borne transmission was high (1480; 97.8%) and 1275 (85.5%) participants were worried about ZIKV infection during pregnancy. The most common preventive behavior was wearing long pants (1355; 89.4%). Regular mosquito repellent use was uncommon (257; 17.0%). While ZIKV knowledge and attitudes were not associated with the adoption of ZIKV prevention behaviors, previous mosquito-borne infection was associated with increased condom use (prevalence ratio 1.4, 95% CI 1.1 to 1.7). Conclusions Participants were well informed about ZIKV transmission and its health consequences. However, whether this knowledge resulted in behavior change is less certain. [ABSTRACT FROM AUTHOR]

- Abstract
Background: COVID-19 outbreak has been associated with a wide variety of psychiatric manifestations such as panic, anxiety, and depression. We aim to assess the impact of the COVID -19 pandemic on the levels of stress and depression of pregnant women in Mexico. Methods: A cross-sectional web survey was carried out in pregnant women in 10 states of the Mexican Republic during the COVID-19 pandemic among public and private hospitals. The perception of stress was assessed using the Perceived Stress Scale, while depressive symptoms were evaluated using the Edinburgh Postnatal Depression Scale. Results: A total of 549 surveys were applied, of which 96.1% (n=503) were included in the data analysis. The mean participant's age was 28.1 years old. The mean perceived stress scale score was 24. 33.2% (n=167) of participants had a score equal to 27 points or more and were considered highly stressed. The mean depression score was 9. A total of 17.5% (n=88) participants had more than 14 points on the Edinburgh's depression scale, and were considered depressed. Stress levels were higher at later gestational ages (p=.008). Conclusions: COVID-19 pandemic has caused mental health issues in pregnant women reflected by high perceived stress levels and depression. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Multiple studies have described increased risk of severe coronavirus disease (COVID‐19) among pregnant women compared to nonpregnant women. The risk in middle‐income countries where the distributions of age groups and preexisting conditions may differ is less known. Objectives: To determine whether pregnant women with SARS‐CoV‐2 infection are at increased risk for severe COVID‐19 compared to nonpregnant women in Colombia. Methods: We analysed national surveillance data from Colombia, of women aged 15–44 years with laboratory‐confirmed infection with SARS‐CoV‐2 by molecular or antigen testing, from 6 March 2020 to 12 December 2020. An enhanced follow‐up of pregnant women with COVID‐19 was established to monitor pregnancy and birth outcomes. Results: Of 371,363 women aged 15–44 years with laboratory‐confirmed SARS‐CoV‐2 infection, 1.5% (n = 5614) were reported as pregnant; among those, 2610 (46.5%) were considered a complete pregnancy for reporting purposes at the time of analysis. Hospitalisation (23.9%) and death (1.3%) occurred more frequently among pregnant symptomatic women compared to nonpregnant symptomatic women (2.9% and 0.3%, respectively). Compared to nonpregnant symptomatic women, pregnant symptomatic women were at increased risk of hospitalisation (adjusted risk ratio [RR] 2.19, 95% confidence interval [CI] 2.07, 2.32) and death (RR 1.82, 95% CI 1.60, 2.07), after adjusting for age, type of health insurance and presence of certain underlying medical conditions. Among complete pregnancies, 55 (2.1%) were pregnancy losses, 72 (2.8%) resulted in term low birthweight infants and 375 (14.4%) were preterm deliveries. Conclusions: Although pregnant women were infrequently reported with laboratory‐confirmed SARS‐CoV‐2 infection, pregnant symptomatic women with COVID‐19 were at increased risk for hospitalisation and death compared to nonpregnant symptomatic women. Almost all infections we reported on were third‐trimester infections; ongoing follow‐up is needed to determine pregnancy outcomes among women infected earlier in pregnancy. Healthcare providers should counsel pregnant women about preventive measures to protect from SARS‐CoV‐2 infection and when to seek care. [ABSTRACT FROM AUTHOR]

Introducción: Los trastornos hipertensivos durante el embarazo representan una importante causa de morbimortalidad perinatal. La prehipertensión ha sido asociada a morbilidad cardiovascular en mujeres no gestantes. El objetivo de este estudio fue evaluar la asociación entre prehipertensión y el desarrollo de desenlaces perinatales adversos en gestantes aparentemente sanas. Métodos: Estudio de cohorte. Escenario: Instituciones de alta complejidad en Bogotá, Colombia. Población: mujeres con menos de 20 semanas de gestación, feto único vivo, con dos o más tomas de tensión arterial en estadio prehipertensivo (tensión arterial sistólica entre 120 y 139 mmHg, tensión arterial diastólica entre 80 y 89 mmHg) con cuatro o más horas de diferencia. Participantes con enfermedades crónicas, gestación producto de técnicas de reproducción asistida, o con diagnóstico de anomalía fetal mayor fueron excluidas. Análisis: Las características basales y desenlaces de la gestación fueron obtenidos de una aplicación sistematizada de historias clínicas. La edad gestacional fue determinada por fecha de última menstruación y confirmada por ecografía. Se realiza comparación de cohortes expuesta y no expuesta. Se realiza un análisis univariado exploratorio y se aplica regresión logística múltiple, ajustando por la presencia de variables de confusión. Resultados Los grupos fueron similares en términos de características clínicas y sociodemográficas. Razones de oportunidades ajustadas y no ajustadas con intervalos de confianza de 95% fueron reportadas. Controlando por edad materna, escolaridad, estado socioeconómico y civil, seguridad social, paridad, consumo de tóxicos y ganancia de peso, se encuentra que la prehipertensión es un factor de riesgo asociado con el desarrollo de preeclampsia (ORa 3.54, 95% CI 1.83–6.83) y hospitalización durante el embarazo (ORa 2.35, 95% CI 1.16–4.76). Conclusión e Implicaciones: Aunque las mujeres con prehipertensión actualmente se clasifican como normales, la prehipertensión en la primera mitad de la gestación aumenta la probabilidad de presentar desenlaces perinatales adversos. Abstract: Hypertension during pregnancy represents an important cause of perinatal morbimortality. Prehypertension has been linked to cardiovascular morbidity in non-pregnant women. The objective of this study was to assess the association between prehypertension and the development of adverse perinatal outcomes in apparently healthy pregnant women. Methods Historical cohort study. Setting: High complexity institutions located in Bogotá, Colombia. Population: Women with less than 20 weeks gestation, single live fetus, with two or more abnormal blood pressure measurements (systolic 120-139 mmHg/diastolic 80-89 mmHg) with six hours apart. Patients with prior diseases, pregnancy resulting from assisted reproduction, or with a diagnosis of fetal abnormality were excluded. Analysis: Baseline characteristics and pregnancy outcomes were retrieved from the computerized medical record. Gestational age was determined by last menstrual period and confirmed by ultrasound. Exposed and non-exposed cohorts were compared. An exploratory univariate regression analysis was performed, and multiple logistic regression was applied, adjusting for the presence of confounding variables. Results The two groups were similar in terms of sociodemographic and clinical characteristics. Adjusted and non-adjusted odds ratios together with the 95% confidence intervals were reported. Controlling for maternal age, scholarly, socioeconomic and civil status, social security, parity, drug abuse and weight gain, it was found that prehypertension was a factor associated with the development of hypertensive disorders (ORa 3.54, 95% CI 1.83–6.83) and hospital care during pregnancy (ORa 2.35, 95% CI 1.16–4.76). Conclusion/Implications Although women with prehypertension are currently classified as normal, prehypertension in the first half of pregnancy increases the likelihood of adverse perinatal outcomes Otra

DELIVERY (Obstetrics) ,MICROCEPHALY ,ZIKA Virus Epidemic, 2015-2016 ,ZIKA virus infections ,ZIKA virus ,VIRAL transmission - Abstract
The marked increase in infants born with microcephaly in Brazil after a 2015 outbreak of Zika virus (Zika virus) disease suggests an association between maternal Zika virus infection and congenital microcephaly. To project the timing of delivery of infants born to mothers infected during early pregnancy in 1 city in Bahia State, Brazil, we incorporated data on reported Zika virus disease cases and microcephaly cases into a graphical schematic of weekly birth cohorts. We projected that these births would occur through February 2016. Applying similar projections to a hypothetical location at which Zika virus transmission started in November, we projected that full-term infants at risk for Zika virus infection would be born during April-September 2016. We also developed a modifiable spreadsheet tool that public health officials and researchers can use for their countries to plan for deliveries of infants to women who were infected with Zika virus during different pregnancy trimesters.

Our aim was to provide a descriptive overview of how the birth defects surveillance and folic acid fortification programs were implemented in Costa Rica-through the establishment of the Registry Center for Congenital Anomalies (Centro de Registro de Enfermedades Congénitas-CREC), and fortification legislation mandates. We estimated the overall prevalence of neural tube defects (i.e., spina bifida, anencephaly and encephalocele) before and after fortification captured by CREC. Prevalence was calculated by dividing the total number of infants born with neural tube defects by the total number of live births in the country (1987-2012).A total of 1,170 newborns with neural tube defects were identified from 1987 to 2012 (1992-1995 data excluded); 628 were identified during the baseline pre-fortification period (1987-1991; 1996-1998); 191 during the fortification period (1999-2002); and 351 during the post-fortification time period (2003-2012). The overall prevalence of neural tube defects decreased from 9.8 per 10,000 live-births (95 % CI 9.1-10.5) for the pre-fortification period to 4.8 per 10,000 live births (95 % CI 4.3-5.3) for the post-fortification period. Results indicate a statistically significant ( P < 0.05) decrease of 51 % in the prevalence of neural tube defects from the pre-fortification period to the post-fortification period. Folic acid fortification via several basic food sources has shown to be a successful public health intervention for Costa Rica. Costa Rica's experience can serve as an example for other countries seeking to develop and strengthen both their birth defects surveillance and fortification programs. [ABSTRACT FROM AUTHOR]

Background: Zika virus infection during pregnancy can cause serious birth defects, which include brain and eye abnormalities. The clinical importance of detection of Zika virus RNA in amniotic fluid is unknown.Objective: The purpose of this study was to describe patterns of Zika virus RNA testing of amniotic fluid relative to other clinical specimens and to examine the association between Zika virus detection in amniotic fluid and Zika-associated birth defects. Our null hypothesis was that Zika virus detection in amniotic fluid was not associated with Zika-associated birth defects.Study Design: We conducted a retrospective cohort analysis of women with amniotic fluid specimens submitted to Colombia's National Institute of Health as part of national Zika virus surveillance from January 2016 to January 2017. Specimens (maternal serum, amniotic fluid, cord blood, umbilical cord tissue, and placental tissue) were tested for the presence of Zika virus RNA with the use of a singleplex or multiplex real-time reverse transcriptase-polymerase chain reaction assay. Birth defect information was abstracted from maternal prenatal and infant birth records and reviewed by expert clinicians. Chi-square and Fisher's exact tests were used to compare the frequency of Zika-associated birth defects (defined as brain abnormalities [with or without microcephaly, but excluding neural tube defects and their associated findings] or eye abnormalities) by frequency of detection of Zika virus RNA in amniotic fluid.Results: Our analysis included 128 women with amniotic fluid specimens. Seventy-five women (58%) had prenatally collected amniotic fluid; 42 women (33%) had amniotic fluid collected at delivery, and 11 women (9%) had missing collection dates. Ninety-one women had both amniotic fluid and other clinical specimens submitted for testing, which allowed for comparison across specimen types. Of those 91 women, 68 had evidence of Zika virus infection based on detection of Zika virus RNA in ≥1 specimen. Testing of amniotic fluid that was collected prenatally or at delivery identified 39 of these Zika virus infections (57%; 15 [22%] infections were identified only in amniotic fluid), and 29 infections (43%) were identified in other specimen types and not amniotic fluid. Among women who were included in the analysis, 89 had pregnancy outcome information available, which allowed for the assessment of the presence of Zika-associated birth defects. Zika-associated birth defects were significantly (P<.05) more common among pregnancies with Zika virus RNA detected in amniotic fluid specimens collected prenatally (19/32 specimens; 59%) than for those with no laboratory evidence of Zika virus infection in any specimen (6/23 specimens; 26%), but the proportion was similar in pregnancies with only Zika virus RNA detected in specimens other than amniotic fluid (10/23 specimens; 43%). Although Zika-associated birth defects were more common among women with any Zika virus RNA detected in amniotic fluid specimens (ie, collected prenatally or at delivery; 21/43 specimens; 49%) than those with no laboratory evidence of Zika virus infection (6/23 specimens; 26%), this comparison did not reach statistical significance (P=.07).Conclusion: Testing of amniotic fluid provided additional evidence for maternal diagnosis of Zika virus infection. Zika-associated birth defects were more common among women with Zika virus RNA that was detected in prenatal amniotic fluid specimens than women with no laboratory evidence of Zika virus infection, but similar to women with Zika virus RNA detected in other, nonamniotic fluid specimen types.

- Abstract
Zika en Embarazadas y Niños (ZEN) is a prospective cohort study designed to identify risk factors and modifiers for Zika virus (ZIKV) infection in pregnant women, partners, and infants, as well as to assess the risk for adverse maternal, fetal, infant, and childhood outcomes of ZIKV and other congenital infections. ZIKV infection during pregnancy may be associated with longterm sequelae. In the ZEN cohort, 1,519 pregnant women and 287 partners were enrolled from 3 departments within Colombia between February 2017 and January 2018, as well as 1,108 infants born to the pregnant women who were followed to 6 months. The data include baseline questionnaires at enrollment; repeated symptoms and study follow-up questionnaires; the results of lab tests to detect ZIKV and other congenital infections; medical record abstractions; infant physical, eye, and hearing exams; and developmental screening tests. Follow-up of 850 mother-child dyads occurred at 9 months, 12 months, and 18 months with developmental screenings, physical exams, and parent questionnaires. The data will be pooled with those from other prospective cohort studies for an individual participant data meta-analysis of ZIKV infection during pregnancy to characterize pregnancy outcomes and sequelae in children.

Background Proyecto Vigilancia de Embarazadas con Zika (VEZ) was an intensified surveillance system built upon existing national surveillance of pregnant women with symptoms of Zika virus (ZIKV) disease and conducted in three Colombian cities with a high prevalence of Zika. This analysis of data from VEZ estimates the risk of Zika-associated birth defects among pregnant women with symptoms of ZIKV disease, and among a subset with laboratory evidence of possible ZIKV infection during pregnancy. Methods During April–November 2016, pregnant women were enrolled if they were reported to the surveillance system (Sivigila) or visited participating clinics with symptoms of ZIKV disease. Maternal and pediatric data were abstracted from prenatal care, ultrasound, and delivery records, as well as from pediatric or specialist visit records. Available maternal and infant specimens were tested for the presence of ZIKV RNA and/or anti-ZIKV immunoglobulin (IgM) antibodies. Results Of 1,223 women enrolled, 47.8% and 34.3% reported first or second trimester symptom onset, respectively. Of 381 pregnancies with maternal and/or infant specimens tested, 108 (29%) had laboratory evidence of possible ZIKV infection during pregnancy; half of these (53.3%) were positive for ZIKV RNA only, 37.4% for IgM antibodies only, and 9.3% for both. Of 1,190 of pregnancies with known outcome, 63 (5%) had Zika-associated brain or eye defects; among the subset with any laboratory evidence, 12 (11%) had Zika-associated brain or eye defects. The prevalence of Zika-associated brain or eye defects was 5.9% (35/593) and 4.5% (19/423) among pregnancies with symptom onset in the first and second trimester, respectively. Conclusion Among pregnant women with symptoms of ZIKV disease enrolled during the height of the ZIKV epidemic in Colombia, prevalence of any Zika-associated brain or eye defect was 5%, with a higher prevalence among those with laboratory evidence of possible ZIKV infection. Rapid enhancements to Colombia's national surveillance enabled the estimation of the risk of birth defects associated with ZIKV disease in pregnancy. Disclosures All Authors: No reported Disclosures.
