Abstract
Since 2016, international research groups have focused on assessing outcomes of children with in utero Zika virus (ZIKV) exposure. While the more severe outcomes of congenital Zika syndrome (CZS) occur in up to 10% of children with antenatal exposure, early findings among ZIKV-exposed children without CZS ages 0-5 years suggest that they may also have differences in multiple domains of neurodevelopment. Thus, longitudinal follow-up of all children with antenatal ZIKV exposure has been recommended. This review presents a summary of neurodevelopmental phenotypes of infants and children following antenatal ZIKV exposure. We present a multidimensional framework to understand child neurodevelopment from an interdisciplinary and whole-child perspective (International Classification of Functioning, Disability and Health model) and multi-domain ZIKV Outcome Toolboxes. The toolboxes are for clinicians, researchers, child educators, and others to implement longitudinal multi-domain neurodevelopmental assessments between ages 0-12 years. Recent innovations in telehealth and neuroimaging can help evaluate outcomes in ZIKV exposed children. The objective is to describe the multiple facets of neurodevelopmental focused care that can support the health, function, and well-being of children with antenatal ZIKV exposure. The research and clinical follow-up strategies are applicable to ZIKV and other congenital infectious or environmental exposures that can impact child neurodevelopment. IMPACT: International longitudinal cohort studies have revealed a range of differences in neurodevelopment among children with antenatal Zika virus (ZIKV) exposure. A multidimensional and whole-child framework is necessary to understand the neurodevelopment of children with antenatal ZIKV exposure in relation to family life, community participation, and environment. Multi-domain toolboxes that utilize parent questionnaires and child evaluations are presented. These toolboxes can be used internationally alongside telehealth, brain imaging, and other innovations to improve understanding of child outcomes.

Abstract
The long-term neurodevelopmental effects of antenatal Zika virus (ZIKV) exposure in children without congenital Zika syndrome (CZS) remain unclear, as few children have been examined to the age of school entry level. A total of 51 Colombian children with antenatal ZIKV exposure without CZS and 70 unexposed controls were evaluated at 4-5 years of age using the Behavior Rating Inventory of Executive Function (BRIEF), the Pediatric Evaluation of Disability Inventory (PEDI-CAT), the Bracken School Readiness Assessment (BSRA), and the Movement Assessment Battery for Children (MABC). The mean ages at evaluation were 5.3 and 5.2 years for cases and controls, respectively. Elevated BRIEF scores in Shift and Emotional Control may suggest lower emotional regulation in cases. A greater number of cases were reported by parents to have behavior and mood problems. BSRA and PEDI-CAT activity scores were unexpectedly higher in cases, most likely related to the COVID-19 pandemic and a delayed school entry among the controls. Although PEDI-CAT mobility scores were lower in cases, there were no differences in motor scores on the MABC. Of 40 cases with neonatal neuroimaging, neurodevelopment in 17 with mild non-specific findings was no different from 23 cases with normal neuroimaging. Normocephalic children with ZIKV exposure have positive developmental trajectories at 4-5 years of age but differ from controls in measures of emotional regulation and adaptive mobility, necessitating continued follow-up.

Abstract
The COVID-19 pandemic occurred during planned neurodevelopmental follow-up of Colombian children with antenatal Zika-virus exposure. The objective of the study was to leverage the institution's telemedicine infrastructure to support international clinical child outcome research. In a prospective cohort study of child neurodevelopment (NCT04398901), we used synchronous telemedicine to remotely train a research team and perform live observational assessments of children in Sabanalarga, Colombia. An observational motor and conceptional standardized tool kit was mailed to Colombia; other materials were translated and emailed; team training was done virtually. Children were recruited by team on the ground. Synchronous activities were video-recorded directly to two laptops, each with a telehealth Zoom link to allow simultaneous evaluation of "table" and "standing" activities, and backup recordings were captured directly on the device in Colombia. The U.S. team attended live over Zoom from four states and five distinct locations, made observational notes, and provided real-time feedback. Fifty-seven, 3-4-year-old children with Zika-virus exposure and 70 non-exposed controls were studied during 10 daytrips. Direct laptop recording ensured complete record of child activities due to internet outages. Telemedicine can be used to successfully perform international neurodevelopmental outcome research in children during the COVID-19 pandemic. Telemedicine can benefit global health studies.

Abstract
BACKGROUND The COVID-19 pandemic has impacted the lives of children and families worldwide. The objective of this study is to examine exposures and impact of the COVID-19 pandemic on preschool-aged children and caregivers in the Atlántico region of Colombia. METHODS The COVID-19 Exposure and Family Impact Scales (CEFIS) questionnaire was administered in Fall 2021 to 63 caregivers of children in Sabanalarga, Colombia enrolled in a neurodevelopment study as healthy controls. The CEFIS assesses pandemic-related exposures/events and impact; higher scores indicate greater exposure and negative impact. Descriptive and correlation analyses among exposure and impact scores were conducted. RESULTS Caregivers reported a mean (standard deviation[SD]) of 11.1 (3.2) among 25 COVID-19-related exposures/events; most common types included stay-at-home orders, school closures, disruptions to living conditions and income loss. Total number of events was correlated with higher caregiver (P < .001) and child distress (P = .002). However, the mean (SD) impact score of 2.0 (0.6) suggests a trend toward more positive impact than negative. Caregivers reported improvements to sleep, exercise and family interactions. Some caregivers (n = 21) qualitatively reported negative effects including unemployment, fear/anxiety and inability to visit family, and positive effects such as unification, family closeness and spending more time with children. CONCLUSIONS This study highlights the importance of comprehensively exploring positive and negative impacts of COVID-19 and families' subsequent resilience and transformation. Using tools like the CEFIS, those seeking to mitigate negative impacts can contextualize data to better understand study outcomes and tailor services, resources and policy to families' unique needs. CEFIS data likely depend on timing, economic/public health resources and cultural values; future work should prioritize understanding the generalizability of CEFIS findings across samples.

Abstract
Abstract
Background
It is unclear whether placental changes in ZIKV infection influence short- and long-term child outcomes. The objective of this study is to determine if placental histopathology findings in ZIKV correlate with offspring outcomes at birth and age 4-5 years for children with in utero ZIKV exposure without congenital Zika syndrome.
Methods
24 placentas collected from pregnant women with symptomatic ZIKV infection enrolled in a prospective ZIKV study in Colombia were formalin fixed and reviewed by a placental pathologist, blinded to child outcome. Children had neuroimaging as newborns and were longitudinally evaluated to age 4-5 years with the Bracken School Readiness Assessment (BSRA) and Pediatric Evaluation of Disability Inventory (PEDI-CAT). Scores were compared by presence of placental findings of perivillous fibrin deposition, calcifications, and increased syncytial knotting. T-test, fisher exact, and one way ANOVA were used for analysis; significance, p< .05.
Results
All 24 placentas had at least one abnormal pathological finding (Table 1). 14 (58%) placentas had extensive ( >30% coverage) and 7 (29%) had mild-moderate perivillous fibrin deposition (Fig. 1a). Placental calcifications were many ( >10) in 10 (42%) cases, and mild in 7 (29%) cases (Fig. 1b). 14 (58%) placentas had increased syncytial knotting. Placentas stained positive with CD163 for Hofbauer macrophages (Fig. 1c). All infants were born at term with normal birth weight, height, and head circumference, and 22 had a normal ponderal index. There was no difference in measurements based on each placental finding. There was no relationship between placental findings and non-specific neuroimaging. 20 (83%) children with placentas were evaluated at age 4-5. Children without placental calcifications scored higher on BSRA than children with mild/severe calcifications (p = .031). Children with increased syncytial knotting had lower scores on PEDI-CAT social/cognitive ability (p = .024).
Conclusion
Placentas from ZIKV-infected pregnancies have pathological findings that indicate risk of impaired fetal perfusion, but these were not associated with preterm birth or growth. There may be associations between placental findings and long-term neurodevelopment in ZIKV-exposed children requiring additional studies.

Abstract
IMPORTANCE The number of children who were born to mothers with Zika virus (ZIKV) infection during pregnancy but who did not have apparent disability at birth is large, warranting the study of the risk for neurodevelopmental impairment in this population without congenital Zika syndrome (CZS). OBJECTIVE To investigate whether infants without CZS but who were exposed to ZIKV in utero have normal neurodevelopmental outcomes until 18 months of age. DESIGN, SETTING, AND PARTICIPANTS This cohort study prospectively enrolled a group of pregnant women with ZIKV in Atlántico Department, Colombia, and in Washington, DC. With this cohort, we performed a longitudinal study of infant neurodevelopment. Infants born between August 1, 2016, and November 30, 2017, were included if they were live born, had normal fetal brain findings on magnetic resonance imaging and ultrasonography, were normocephalic at birth, and had normal examination results without clinical evidence of CZS. Seventy-seven infants born in Colombia, but 0 infants born in the United States, met the inclusion criteria. EXPOSURES Prenatal ZIKV exposure. MAIN OUTCOMES AND MEASURES Infant development was assessed by the Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA) and the Alberta Infant Motor Scale (AIMS) at 1 or 2 time points between 4 and 18 months of age. The WIDEA and AIMS scores were converted to z scores compared with normative samples. Longitudinal mixed-effects regression models based on bootstrap resampling methods estimated scores over time, accounting for gestational age at maternal ZIKV infection and infant age at assessment. Results were presented as slope coefficients with 2-tailed P values based on z statistics that tested whether the coefficient differed from 0 (no change). RESULTS Of the 77 Colombian infants included in this cohort study, 70 (91%) had no CZS and underwent neurodevelopmental assessments. Forty infants (57%) were evaluated between 4 and 8 months of age at a median (interquartile range [IQR]) age of 5.9 (5.3-6.5) months, and 60 (86%) underwent assessment between 9 and 18 months of age at a median (IQR) age of 13.0 (11.2-16.4) months. The WIDEA total score (coefficients: age = -0.227 vs age2 = 0.006; P < .003) and self-care domain score (coefficients: age = -0.238 vs age2 = 0.01; P < .008) showed curvilinear associations with age. Other domain scores showed linear declines with increasing age based on coefficients for communication (-0.036; P = .001), social cognition (-0.10; P < .001), and mobility (-0.14; P < .001). The AIMS scores were similar to the normative sample over time (95% CI, -0.107 to 0.037; P = .34). Nineteen of 57 infants (33%) who underwent postnatal cranial ultrasonography had a nonspecific, mild finding. No difference was found in the decline of WIDEA z scores between infants with and those without cranial ultrasonography findings except for a complex interactive relationship involving the social cognition domain (P < .049). The AIMS z scores were lower in infants with nonspecific cranial ultrasonography findings (-0.49; P = .07). CONCLUSIONS AND RELEVANCE This study found that infants with in utero ZIKV exposure without CZS appeared at risk for abnormal neurodevelopmental outcomes in the first 18 months of life. Long-term neurodevelopmental surveillance of all newborns with ZIKV exposure is recommended.

Abstract
Abstract
Background
Congenital Zika syndrome (CZS) is seen in 5–12% of newborns from Zika virus (ZIKV)-infected pregnancies and includes severe neurologic abnormalities. However, the majority of ZIKV-exposed newborns do not have CZS. The risk for neurodevelopmental impairment for infants without CZS following in utero ZIKV is not well known. The objective was to determine whether infants without CZS exposed to ZIKV in utero, have normal neurodevelopment.
Methods
We performed a longitudinal study of neurodevelopment in Colombia for infants exposed to ZIKV in utero who had a normal fetal brain MRI (Mulkey et al, JAMA Peds 2019) and normal head circumference at birth. Infant development was assessed by the Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA) and the Alberta Infant Motor Scale (AIMS) between 6 and 18 months of age. In-person training was done by a neurologist. The AIMS were video-recorded and scored centrally. Interrater reliability for the novel method of video-based AIMS was determined. WIDEA and AIMS scores were converted to Z-scores compared with normative samples. We also compared development between infants with normal and nonspecific findings on cranial ultrasound (US).
Results
Seventy-two non-CZS infants had neurodevelopmental tests; 40 were at a mean (SD) of 5.7 (0.9) months and 66 were at 13.5 (3.2) months of age. Thirty-four had two assessments. The total WIDEA, social cognition, and mobility domain scores became more abnormal with postnatal age (figure). The AIMS scores were similar to the normative sample. Three infants had an AIMS score < 2 SD’s below the norm. On cranial US, 19 infants (26%) had a nonspecific finding (lenticulostriate vasculopathy, choroid plexus cysts, subependymal cysts, and/or calcification). Infants with a US finding had a lower WIDEA mobility score than infants with normal US (P = .054). There was a trend toward lower AIMS scores in infants with US findings compared with infants with normal US (P = .26). AIMS Interrater agreement on video-based scoring was good (ICC = 0.73, 95% CI 0.42, 0.87).
Conclusion
ZIKV-exposed infants without CZS are at risk for neurodevelopmental delay. Nonspecific cranial US findings may represent mild ZIKV-related injury. Long-term neurodevelopmental follow-up is important for all ZIKV-exposed infants.

Abstract
IMPORTANCE The evolution of fetal brain injury by Zika virus (ZIKV) infection is not well described. OBJECTIVES To perform longitudinal neuroimaging of fetuses and infants exposed to in utero maternal ZIKV infection using concomitant magnetic resonance imaging (MRI) and ultrasonography (US), as well as to determine the duration of viremia in pregnant women with ZIKV infection and whether the duration of viremia correlated with fetal and/or infant brain abnormalities. DESIGN, SETTING, AND PARTICIPANTS A cohort of 82 pregnant women with clinical criteria for probable ZIKV infection in Barranquilla, Colombia, and Washington, DC, were enrolled from June 15, 2016, through June 27, 2017, with Colombian women identified by community recruitment and physician referral and travel-related cases of American women recruited from a Congenital Zika Program. INTERVENTIONS AND EXPOSURES Women received 1 or more MRI and US examinations during the second and/or third trimesters. Postnatally, infants underwent brain MRI and cranial US. Blood samples were tested for ZIKV. MAIN OUTCOMES AND MEASURES The neuroimaging studies were evaluated for brain injury and cerebral biometry. RESULTS Of the 82 women, 80 were from Colombia and 2 were from the United States. In 3 of 82 cases (4%), fetal MRI demonstrated abnormalities consistent with congenital ZIKV infection. Two cases had heterotopias and malformations in cortical development and 1 case had a parietal encephalocele, Chiari II malformation, and microcephaly. In 1 case, US results remained normal despite fetal abnormalities detected on MRI. Prolonged maternal polymerase chain reaction positivity was present in 1 case. Of the remaining 79 cases with normal results of prenatal imaging, postnatal brain MRI was acquired in 53 infants and demonstrated mild abnormalities in 7 (13%). Fifty-seven infants underwent postnatal cranial US, which detected changes of lenticulostriate vasculopathy, choroid plexus cysts, germinolytic/subependymal cysts, and/or calcification in 21 infants (37%). CONCLUSIONS AND RELEVANCE In a cohort of pregnant women with ZIKV infection, prenatal US examination appeared to detect all but 1 abnormal fetal case. Postnatal neuroimaging in infants who had normal prenatal imaging revealed new mild abnormalities. For most patients, prenatal and postnatal US may identify ZIKV-related brain injury.

Abstract
Background Up to 15% of pregnancies complicated by maternal ZIKV infection result in Zika-virus associated brain abnormalities in the fetus/newborn. Fetal ultrasound (feUS) is the standard imaging modality for the evaluation of fetal anatomy and for brain changes from congenital infection. Fetal MRI (feMRI) may be a useful adjunct. Methods We performed a prospective longitudinal neuroimaging study of fetuses/newborns of pregnant women with clinical and/or lab confirmed (RT-PCR and/or IgM/PRNT) diagnosis of Zika infection in Barranquilla, Colombia (endemic) and in Washington, DC, USA (travel-related). Gestational age (GA) at exposure and timing between ZIKV exposure/symptoms and imaging was documented. Subjects had one to two feMRIs and feUS, depending upon GA at enrollment. The feMRI and feUS protocols were standardized between sites and studies were centrally interpreted at Children’s National. Postnatally, infants received an unsedated brain MRI and head US. Results Forty-eight, ZIKV exposed/infected in first or second trimester pregnant women were enrolled (46 Colombia, 2 USA). Subjects had symptoms of ZIKV infection at mean of 8.4±5.7 week GA. The first feMRI and feUS were performed at 25.1±6.3 week GA. Thirty-six infants had a second feMRI and feUS at 31.1±4.2 week GA. Three of 48 (6%) cases had an abnormal feMRI: (1) heterotopias and abnormal cortical indent; (2) parietal encephalocele and Chiari II; (3) thin corpus callosum, dysplastic brainstem, temporal cysts, subependymal heterotopias, and generalized cerebral/cerebellar atrophy. FeUS in these three cases found (1) normal study; (2) parietal encephalocele and Chiari II; (3) significant ventriculomegaly with decreasing percentiles of head circumference from 32 to 36 week GA (38% to 3.6%). Postnatal head US revealed findings not seen on feUS: choroid plexus or germinal matrix cysts in nine infants and lenticulostriate vasculopathy in one infant. Conclusion FeMRI and feUS provide complimentary information in the assessment of fetal brain changes in ZIKV. In cases of abnormal brain structure, feMRI reveals more extensive areas of brain damage than is seen by US. Further studies are needed to determine whether cystic changes on postnatal head US are related to ZIKV infection, or are incidental findings. Disclosures All authors: No reported disclosures.
