Adherence of Brazilian Minors to the 24-Hour Movement Guidelines after In-Person School Return.

The levels of adequacy of movement behaviors after returning to in-person school activities following the COVID-19 pandemic are not yet well understood. This study aimed to assess the adherence of Brazilian minors to the recommendations of the 24-Hour Movement Guidelines (moderate to vigorous physical activity, recreational screen time, and sleep duration), as well as overall adherence to these guidelines, after the relaxation of COVID-19 social isolation measures and the resumption of in-person schooling. A cross-sectional study was conducted with parents or guardians (39 ± 7.8) of minors aged up to 18 years of age (3.8 ± 2.5). A total of 172 individuals responded to the questionnaire. Data were compared with those obtained in the Survey of the Adequacy of Brazilian Children and Adolescents to the 24-Hour Movement Guidelines before and during the COVID-19 Pandemic. There was an 18.6 percentage decrease (p-value < 0.001) in overall adherence to the 24-Hour Movement Guidelines when comparing the periods before the COVID-19 pandemic (March 2020) and after the return to in-person schooling (March 2021). The largest percentage drop in adherence between these periods was observed for moderate to vigorous physical activity (27.4%; p-value < 0.001) and the lowest for sleep (10.5%; p-value < 0.001). Adherence to the 24-Hour Movement Guidelines did not return to pre-pandemic levels with the resumption of in-person school activities.

The cost of genetic diagnosis of suspected hereditary pediatric cataracts with whole-exome sequencing from a middle-income country perspective: a mixed costing analysis.

Up to 25% of pediatric cataract cases are inherited. There is sparse information in the literature regarding the cost of whole-exome sequencing (WES) for suspected hereditary pediatric cataracts. Molecular diagnosis of suspected hereditary pediatric cataracts is important for comprehensive genetic counseling. We performed a partial economic evaluation with a mixed costing analysis, using reimbursement data and microcosting approach with a bottom-up technique to estimate the cost of using WES for genetic diagnosis of suspected hereditary pediatric cataracts from the perspective of the Brazilian governmental health care system. One hundred and ten participants from twenty-nine families in Rio de Janeiro (RJ) were included. Costs of consumables, staff and equipment were calculated. Two scenarios were created: (1) The reference scenario included patients from RJ with suspected hereditary pediatric cataracts plus two family members. (2) The alternative scenario considered other genetic diseases, resulting in 5,280 exams per month. Sensitivity analysis was also performed. In the reference scenario, the total cost per exam was 700.09 United States dollars (USD), and in the alternative scenario, the total cost was 559.23 USD. The cost of WES alone was 527.85 USD in the reference scenario and 386.98 USD in the alternative scenario. Sensitivity analysis revealed that the largest costs were associated with consumables in both scenarios. Economic evaluations can help inform policy decisions, especially in middle-income countries such as Brazil.

Gasto catastrófico em crianças com deficiência visual: estudo transversal com cuidadores no Rio de Janeiro, Brasil / Catastrophic expenditure in children with visual impairment: a cross-sectional study with caregivers in Rio de Janeiro, Brazil / Gasto catastrófico en niños con discapacidad visual: estudio transversal con cuidadores en Río de Janeiro, Brasil

Resumo: O cuidado de um filho com deficiência visual pode vir a afetar a renda do cuidador e, por sua vez, a renda da família. Sob essa realidade, há de se considerar o gasto catastrófico consequente do aumento de despesas e da redução de renda, seja pelo desemprego, pela redução do número de horas trabalhadas ou pela dificuldade de (re)inserção no mercado de trabalho. Perante esse cenário, o objetivo principal deste estudo foi estimar o gasto catastrófico atribuído ao cuidador de crianças cegas ou com baixa visão em centros de referência em educação para cegos, oftalmologia e saúde infantil localizados no Município do Rio de Janeiro, Brasil, identificando quais fatores estão associados a uma maior ou menor prevalência desse gasto. Observou-se que 53,3% dos cuidados de crianças com cegueira comprometem 40% ou mais da renda. Entre os cuidadores de crianças com baixa visão, o gasto catastrófico é mais ameno, comprometendo no mínimo 40% da renda para 36,8% dos cuidadores. Os fatores associados à maior prevalência de gasto catastrófico foram idade do cuidador, número de moradores na residência, maior escolaridade, menor renda domiciliar, reformas na residência, plano de saúde, aquisição de empréstimos, venda de bens, quantidade de unidades de saúde que a criança recebe tratamento e parentesco do cuidador principal. A carga que recai sobre os cuidadores de crianças com deficiência visual indica uma situação de vulnerabilidade que mostra a necessidade de acesso aos mecanismos de proteção financeira e social, por meio de políticas que sejam capazes de atender esse grupo.

Abstract: Caring for a visually impaired child can affect the caregiver's income and, in turn, the family's. Catastrophic spending resulting from increased expenses and reduced income must be taken into account, whether due to unemployment, a reduction in the number of hours worked or the difficulty of entering or reentering the job market. Given this scenario, the main objective of this study was to estimate the catastrophic spending attributed to the caregiver of blind or low-vision children in reference centers for education for the blind, ophthalmology and child health located in the city of Rio de Janeiro, Brazil, identifying which factors are associated with a higher or lower prevalence of this expenditure. It was found that 53.3% of care for blind children involved 40% or more of their income. Among the caregivers of children with low vision, catastrophic spending is milder, compromising at least 40% of income for 36.8% of the caregivers. The factors associated with a higher prevalence of catastrophic spending were the caregiver's age, the number of residents in the household, higher schooling, lower household income, renovations to the home, health insurance, taking out loans, selling assets, the number of health units where the child receives treatment and the relationship of the main caregiver. The burden placed on caregivers of visually impaired children indicates a situation of vulnerability that shows the need for access to financial and social protection mechanisms, through policies that are capable of serving this group.

Resumen: El cuidado de un niño con discapacidad visual puede impactar los ingresos del cuidador y, a su vez, de la familia. En este escenario, es necesario considerar el gasto catastrófico resultante del aumento de los gastos o la reducción de los ingresos, ya sea por desempleo, reducción del número de horas trabajadas o por la dificultad de inserción o reinserción en el mercado laboral. Ante esto, el objetivo principal de este estudio fue estimar el gasto catastrófico atribuido al cuidador de niños ciegos o con baja visión en centros de referencia en educación para ciegos, oftalmología y salud infantil, ubicados en el municipio de Río de Janeiro, Brasil, con el fin de identificar qué factores se asocian con una mayor o menor prevalencia de este gasto. Se observó que el 53,3% de los cuidados de niños con discapacidad visual comprometen más del 40% de los ingresos totales. Mientras tanto, el cuidado de niños con baja visión tiene un menor gasto catastrófico, comprometiendo menos del 40% de los ingresos según el 36,8% de los cuidadores. La mayor prevalencia de gasto catastrófico estuvo asociada a los siguientes factores: edad del cuidador, número de residentes en el hogar, mayor nivel de estudios, bajos ingresos familiares, remodelaciones en el hogar, seguro de salud, adquisición de préstamos, venta de bienes, cantidad de centros de salud en las que el niño acude al tratamiento y parentesco del cuidador principal. Los cuidadores de niños con discapacidad visual enfrentan una situación de vulnerabilidad, lo que apunta a una necesidad de acceder a acciones de protección financiera y social mediante políticas dirigidas a esta población.

[Depression, anxiety, stress, and social support: a cross-sectional study with caregivers of visually impaired children in Rio de Janeiro, Brazil - Views-QoL Study]. / Depressão, ansiedade, estresse e apoio social: estudo transversal com cuidadores de crianças com deficiência visual no Rio de Janeiro, Brasil - Views-QoL Study.

We aimed to identify the reports of symptoms of depression, anxiety, and stress among caregivers of children without visual impairment, with low vision, and with blindness and their relationship with the degree of social, emotional, material, and affective support. This cross-sectional and multicenter study was conducted in the municipality of Rio de Janeiro, Brazil, from 2019 to 2020. A questionnaire was applied to obtain caregivers' sociodemographic and economic data. The Medical Outcomes Study Social Support Scale (MOS-SSS) and The Depression, Anxiety, and Stress Scale (DASS-21) were used. Tests were used for multiple comparisons of these scales. The prevalence ratio of symptoms of depression, anxiety, and stress was estimated. Of all caregivers (N = 355), more than 90% were women-mothers. Caregivers of children with visual impairment show the highest proportion of no schooling, incomplete elementary education, or lower average monthly income. Most caregivers of children with blindness reported symptoms of depression, anxiety, and stress (66.7%, 73.3%, and 80%, respectively) as did those of children with low vision. The evaluation of the relationship between MOS-SSS and DASS-21 results shows greater support and lower scores of reports of depression, anxiety, and stress for caregivers of children without disabilities or with less visual impairment. For caregivers of blind children, the highest prevalence of such reports was independent of the received support. Results indicate the need for a care policy with mechanisms to protect the mental health of caregivers of visually impaired children.

O objetivo foi identificar os relatos de sintomas de depressão, ansiedade e estresse entre cuidadores de crianças sem deficiência visual, com baixa visão e com cegueira e sua relação com o grau de apoio social, emocional, material e afetivo. Estudo transversal e multicêntrico, realizado no Município do Rio de Janeiro, Brasil, entre 2019 e 2020. Aplicou-se um questionário para obter dados sociodemográficos e econômicos do cuidador. Foram utilizadas a Escala de Apoio Social (The Medical Outcomes Study Social Support Scale - MOS-SSS) e a Escala de Depressão, Ansiedade e Estresse (The Depression, Anxiety, and Stress Scale - DASS-21). Na comparação entre as escalas, foram utilizados testes para comparações múltiplas. Estimou-se a razão de prevalência de sintomas de depressão, ansiedade e estresse. Do total de cuidadores (N = 355), mais de 90% eram mulheres-mães e a maior proporção de cuidadores sem instrução ou Ensino Fundamental incompleto e com menor renda média mensal foi daqueles de crianças com deficiência visual. A maioria dos cuidadores de crianças com cegueira relatou sintomas de depressão, ansiedade e estresse (respectivamente, 66,7%, 73,3% e 80%), mesmo comportamento observado no grupo de cuidadores de crianças com baixa visão. Na avaliação da relação entre os resultados das escalas MOS-SSS e DASS-21, entre os cuidadores de crianças sem deficiência ou com menor comprometimento visual, observou-se maiores apoios e menores escores de relatos de depressão, ansiedade e estresse. Entre os cuidadores de crianças cegas, as maiores prevalências não dependeram dos apoios recebidos. Os resultados indicam a necessidade de uma política de cuidado com mecanismos de proteção à saúde mental dos cuidadores de crianças com deficiência visual.

Los resultados indican la necesidad de una Política de Cuidado con mecanismos para proteger la salud mental de los cuidadores de niños con discapacidad visual.

Evaluation and monitoring of eye findings in children exposed to Zika virus during gestation: 3 years of follow-up.

INTRODUCTION: Congenital Zika syndrome (CZS) is a recently described disease. Our main objective was to evaluate and monitor, over 3 years, the ophthalmoscopic findings in children exposed to zika virus (ZIKV) during gestation. METHODS: This prospective observational study was conducted in Rio de Janeiro, Brazil, between April 2016 and May 2019. We evaluated two groups with exanthema serving as a proxy for viremia: (i) children whose mothers had exanthema during pregnancy and (ii) children who had microcephaly without maternal exanthema during pregnancy. We performed indirect ophthalmoscopy at recruitment and every 6 months thereafter. We also tested the association between ocular findings with maternal exanthema, microcephaly, CZS and maternal infection confirmed by reverse transcriptase quantitative polymerase chain reaction and gender. RESULTS: Of the 72 children included, 16 (22.2%) had optic nerve and/or retinal lesions. All 16 had CZS and 15 (93.7%) had microcephaly (14 at birth and 1 postnatally). The child with postnatally acquired microcephaly was born to a mother without exanthema during pregnancy. Fifty-six (77.8%) of the 72 children were followed for a median time of 24 months and none exhibited differences between admission and follow-up examinations. After logistic regression, only microcephaly at birth was associated with eye abnormalities (odds ratio, 77.015; 95% confidence interval, 8.85-670.38; p < 0.001). CONCLUSION: We observed that there was no progression of the lesions over the follow-up period. We also showed that the eye findings were associated only with microcephaly at birth. Attention should be paid to all children born during a ZIKV epidemic, regardless of maternal exanthema and/or microcephaly at birth.

Genotypic-Phenotypic Correlations of Hereditary Hyperferritinemia-Cataract Syndrome: Case Series of Three Brazilian Families.

Hereditary hyperferritinemia-cataract syndrome (HHCS) is a rare, frequently misdiagnosed, autosomal dominant disease caused by mutations in the FTL gene. It causes bilateral pediatric cataract and hyperferritinemia without iron overload. The objective of this case series, describing three Brazilian families, is to increase awareness of HHCS, as well as to discuss possible phenotypic interactions with concurrent mutations in HFE, the gene associated with autosomal recessive inheritance hereditary hemochromatosis. Whole-exome sequencing was performed in eight individuals with HHCS from three different families, as well as one unaffected member from each family for trio analysis-a total of eleven individuals. Ophthalmological and clinical genetic evaluations were conducted. The likely pathogenic variant c.-157G>A in FTL was found in all affected individuals. They presented slowly progressing bilateral cataract symptoms before the age of 14, with a phenotype of varied bilateral diffuse opacities. Hyperferritinemia was present in all affected members, varying from 971 ng/mL to 4899 ng/mL. There were two affected individuals with one concurrent pathogenic variant in HFE (c.187C>G, p.H63D), who were also the ones with the highest values of serum ferritin in our cohort. Few publications describe individuals with pathogenic mutations in both FTL and HFE genes, and further studies are needed to assess possible phenotypic interactions causing higher values of hyperferritinemia.

Zika virus infection histories in brain development.

An outbreak of births of microcephalic patients in Brazil motivated multiple studies on this incident. The data left no doubt that infection by Zika virus (ZIKV) was the cause, and that this virus promotes reduction in neuron numbers and neuronal death. Analysis of patients' characteristics revealed additional aspects of the pathology alongside the decrease in neuronal number. Here, we review the data from human, molecular, cell and animal model studies attempting to build the natural history of ZIKV in the embryonic central nervous system (CNS). We discuss how identifying the timing of infection and the pathways through which ZIKV may infect and spread through the CNS can help explain the diversity of phenotypes found in congenital ZIKV syndrome (CZVS). We suggest that intraneuronal viral transport is the primary mechanism of ZIKV spread in the embryonic brain and is responsible for most cases of CZVS. According to this hypothesis, the viral transport through the blood-brain barrier and cerebrospinal fluid is responsible for more severe pathologies in which ZIKV-induced malformations occur along the entire anteroposterior CNS axis.

Survey of the Adequacy of Brazilian Children and Adolescents to the 24-Hour Movement Guidelines before and during the COVID-19 Pandemic.

The 24-Hour Movement Guidelines provide specific recommendations on movement behaviors for children and adolescents. The objective of this study was to verify the adequacy of children and adolescents to the guidelines for moderate to vigorous physical activity, recreational screen time, and sleep duration, and the overall adequacy to the guidelines, before and during the COVID-19 pandemic. A cross-sectional study was conducted with parents or guardians of children or adolescents from different regions of Brazil using a digital interview form including sociodemographic characteristics of families, moderate to vigorous physical activity, recreational screen time, and sleep duration before and during the pandemic. Statistically significant variation was observed in both groups in relation to moderate to vigorous physical activity and recreational screen time between the two periods evaluated. Overall adequacy to the guidelines before the pandemic was 19.28% for children from Group 1 (0-5 years old) and 39.50% for those from Group 2 (6 to 17 years old). During the pandemic, it corresponded to 3.58% in Group 1 and 4.94% in Group 2 (p-value between periods ≤0.001). This study showed the significant impact of pandemic restrictions on reducing overall compliance and physical activity, and increasing screen time among Brazilian children and adolescents.

Current practices and profiles of ophthalmologists involved in retinopathy of prematurity care in Brazil.

Retinopathy of prematurity (ROP) care in Brazil varies in availability of resources and infrastructure. A cross-sectional survey was conducted among ophthalmologists of the Brazilian ROP Group (BRA-ROP) to assess the profiles and practices of ophthalmologists involved in ROP care. A total of 78 responses of BRA-ROP participants (79%) were included. Participants were mostly retina experts (64.1%), female (65.4%), and over 40 years of age (60.2%). Eighty-six percent reported following Brazil's ROP screening criteria. Retinal imaging is available to 16.9% of respondents; fluorescein angiography, to 1.4%. For ROP stage 3 zone II (with plus disease), laser treatment was the preferred treatment (78.9%); for aggressive ROP, anti-VEGF was favored (66.2%). There were significant regional differences in treatment choice. Not all respondents continued to follow treated patients after discharge from the neonatal intensive care unit, highlighting an aspect of ROP care in need of improvement.

Risk of adverse outcomes in offspring with RT-PCR confirmed prenatal Zika virus exposure: An individual participant data meta-analysis of 13 cohorts in the Zika Brazilian Cohorts Consortium.

Background: Knowledge regarding the risks associated with Zika virus (ZIKV) infections in pregnancy has relied on individual studies with relatively small sample sizes and variable risk estimates of adverse outcomes, or on surveillance or routinely collected data. Using data from the Zika Brazilian Cohorts Consortium, this study aims, to estimate the risk of adverse outcomes among offspring of women with RT-PCR-confirmed ZIKV infection during pregnancy and to explore heterogeneity between studies. Methods: We performed an individual participant data meta-analysis of the offspring of 1548 pregnant women from 13 studies, using one and two-stage meta-analyses to estimate the absolute risks. Findings: Of the 1548 ZIKV-exposed pregnancies, the risk of miscarriage was 0.9%, while the risk of stillbirth was 0.3%. Among the pregnancies with liveborn children, the risk of prematurity was 10,5%, the risk of low birth weight was 7.7, and the risk of small for gestational age (SGA) was 16.2%. For other abnormalities, the absolute risks were: 2.6% for microcephaly at birth or first evaluation, 4.0% for microcephaly at any time during follow-up, 7.9% for neuroimaging abnormalities, 18.7% for functional neurological abnormalities, 4.0% for ophthalmic abnormalities, 6.4% for auditory abnormalities, 0.6% for arthrogryposis, and 1.5% for dysphagia. This risk was similar in all sites studied and in different socioeconomic conditions, indicating that there are not likely to be other factors modifying this association. Interpretation: This study based on prospectively collected data generates the most robust evidence to date on the risks of congenital ZIKV infections over the early life course. Overall, approximately one-third of liveborn children with prenatal ZIKV exposure presented with at least one abnormality compatible with congenital infection, while the risk to present with at least two abnormalities in combination was less than 1.0%.

Evaluation of childhood cataract characteristics at a tertiary referral center / Características de catarata na infância em um centro de referência terciário

ABSTRACT Purpose: To examine the epidemiological characteristics of children undergoing cataract surgery at a referral center in Sao Paulo State, Brazil, as well as the facts surrounding treatment delays. Methods: In this transversal observational study, 240 operated eyes from 178 children undergoing cataract surgery were reviewed. The following aspects were analyzed: epidemiological and clinical characteristics, parental observations, red reflex test, operated eye, and age at cataract diagnosis and surgery. Results: The mean ages at the first visit and cataract surgery were 48.9 months (SD=50.0 months) and 64.5 months (SD= 55.4 months), respectively. The most critical sign adverted by parents was leukocoria. The red reflex test was performed on two-thirds of the children, with abnormal results in 28.0%. A family history of cataracts was evident in 30 (20,9%) children (n=144). Previous ocular surgery was found in 37 (16,6%) of the eyes (n=223), anterior segment disorders in 20 (9,0%) eyes (n=221), strabismus in 21 (9,5%) of the eyes (n=220), and nystagmus in 38 (24,4%) of the children (n=156). Conclusions: One of the causes for the delay in admission may have been the failure to complete the red reflex. In terms of etiology, heredity was the most crucial component. The presence of strabismus and nystagmus in many of these children points to late diagnosis. The most significant impediments to adequate cataract treatment in children were the lack of referral programs and children's specialized ophthalmologic centers, in addition to the restricted number of support professionals trained in the field and pediatric ophthalmology specialists.

RESUMO Objetivos: Rever características epidemiológicas de crianças submetidas a cirurgia de catarata, em centro de referência no estado de São Paulo, Brasil, e fatos associados a atrasos no tratamento. Métodos: Um total de 240 olhos submetidos a cirurgia de catarata, em 178 crianças, foram revisados neste estudo transversal observacional. Os seguintes aspectos foram analisados: características clínicas e epidemiológicas, sinais apontados pelos pais, teste do reflexo vermelho, olho operado e idade no diagnóstico e na cirurgia. Resultados: A média de idades na primeira visita e cirurgia de catarata foi de 48.9 meses (DP=50,0 meses) e 64.5 meses (DP=55.4 meses), respectivamente. O sinal mais importante apontado pelos pais foi a leucocoria. O teste do reflexo vermelho foi realizado em dois terços das crianças com resultados anormais em 28%. Histórico familiar de catarata foi evidente em 30 (20,9%) crianças (n=144). Os achados mais prevalentes em termos de histórico de problemas oculares foram: cirurgias oculares prévias em 37 (16,6%) olhos (n= 223), alterações do segmento anterior em 20 (9,0%) olhos (n=221), estrabismo em 21 (9,5%) olhos (n=220) e nistagmo em 38 (24,4%) crianças (n=156). Conclusões: Uma das causas para o atraso na admissão pode ter sido a falha em realizar o teste do reflexo vermelho, apesar de não ter sido possível verificar se todas as crianças foram submetidas ao exame. A hereditariedade foi o fator mais importante quanto à causa da catarata nessas crianças. A presença de estrabismo e nistagmo mais uma vez aponta para o diagnóstico tardio. Ausência de programas de referência e centros oftalmológicos especializados em crianças, além do número restrito de profissionais de apoio treinados na área e especialistas em oftalmologia pediátrica, foram as barreiras mais importantes para o tratamento adequado da catarata em crianças.

Los resultados indican la necesidad de una Política de Cuidado con mecanismos para proteger la salud mental de los cuidadores de niños con discapacidad visual.

Acquired Hip Dysplasia in Children with Congenital Zika Virus Infection in the First Four Years of Life.

Acquired hip dysplasia has been described in children with cerebral palsy (CP); periodic surveillance is recommended in this population to prevent hip displacement and dislocation. Children with congenital zika syndrome (CZS) may present a spectrum of neurological impairments with changes in tonus, posture, and movement similar to children with CP. However, the relationship between CZS and hip dysplasia has not been characterized. In this prospective cohort study, we aimed to describe the occurrence of hip dysplasia in patients with CZS. Sixty-four children with CZS from 6 to 48 months of age were included and followed at a tertiary referral center in Rio de Janeiro, Brazil, with periodic radiologic and clinical hip assessments. Twenty-six (41%) patients were diagnosed with hip dysplasia during follow-up; mean age at diagnosis was 23 months. According to the Gross Motor Function Classification System (GMFCS), 58 (91%) patients had severe impairment (GMFCS IV and V) at the first evaluation. All patients with progression to hip dysplasia had microcephaly and were classified as GMFCS IV or V. Pain and functional limitation were reported by 22 (84%) caregivers of children with hip dysplasia. All patients were referred to specialized orthopedic care; eight (31%) underwent surgical treatment during follow-up. Our findings highlight the importance of implementing a hip surveillance program and improving access to orthopedic treatment for children with CZS in order to decrease the chances of dysplasia-related complications and improve quality of life.

The presence of strabismus and nystagmus in many of these children points to late diagnosis. The most significant impediments to adequate cataract treatment in children were the lack of referral programs and children's specialized ophthalmologic centers, in addition to the restricted number of support professionals trained in the field and pediatric ophthalmology specialists.

Portable wide-field digital imaging for screening of neonatal visual impairment causes in Rio de Janeiro, Brazil: a budget impact analysis.

OBJECTIVE: To estimate the budget impact of portable wide-field digital imaging incorporation on screening neonatal causes of childhood blindness and visual impairment in Rio de Janeiro, Brazil. DESIGN: Budget impact analysis. SETTING: Rio de Janeiro, Brazil. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the direct cost of indirect binocular ophthalmoscopy, red reflex test and portable wide-field digital image screening comprising all babies born in Rio de Janeiro's government maternity wards. The secondary outcome was the budget impact of implementing portable wide-field digital image screening in Rio de Janeiro, Brazil. RESULTS: Considering 100% coverage of maternity wards, the total budget impact between 2020 and 2024 would be US$3 820 706.04, ranging from US$3 139 844.34 to US$6 099 510.35. The additional cost would be US$3 124 457.28, ranging from US$2 714 492.26 to US$4 880 608.63. CONCLUSION: The cost of universal digital imaging screening corresponds to less than 1% of the government health budget of the city of Rio de Janeiro. The information provided in this study may help government decision-makers evaluate the feasibility of implementing this new strategy in the municipal setting. Further health economic evaluations should be performed to verify the affordability of the implementation of this screening strategy in the Brazilian scenario, taking into account scarce human resources.

Anthropometric Parameters of Children with Congenital Zika Virus Exposure in the First Three Years of Life.

Little is known about the impact of congenital Zika virus (ZIKV) exposure on growth in the first years of life. In this prospective cohort study,201 ZIKV antenatally-exposed children were followed at a tertiary referral center in Rio de Janeiro, Brazil. Eighty-seven were classified as congenital Zika syndrome (CZS) patients and 114 as not congenital Zika syndrome (NCZS); growth parameters were described and compared between groups and with WHO standard growth curves. Thirty-four (39%) newborns with CZS and seven (6%) NCZS were small for gestational age (p < 0.001). NCZS mean weight measures ranged from −0.45 ± 0.1 to 0.27 ± 0.2 standard deviations (SD) from the WHO growth curve median during follow-up, versus −1.84 ± 0.2 to −2.15 ± 0.2 SD for the CZS group (p < 0.001). Length mean z-scores varied from −0.3 ± 0.1 at 1 month to 0.17 ± 0.2 SD between 31 and 36 months in the NCZS group, versus −2.3 ± 0.3 to −2.0 ± 0.17 SD in the CZS group (p < 0.001). Weight/height (W/H) and BMI z-scores reached -1.45 ± 0.2 SD in CZS patients between 31 and 36 months, versus 0.23 ± 0.2 SD in the NCZS group (p < 0.01). Between 25 and 36 months of age, more than 50% of the 70 evaluated CZS children were below weight and height limits; 36 (37.1%) were below the W/H cut-off. Gastrostomy was performed in 23 (26%) children with CZS. During the first three years of life, CZS patients had severe and early growth deficits, while growth of NCZS children was normal by WHO standards.

Early Predictors of Poor Neurologic Outcomes in a Prospective Cohort of Infants With Antenatal Exposure to Zika Virus.

BACKGROUND: Identify early predictors of poor neurodevelopment in infants with antenatal Zika virus (ZIKV) exposure. METHODS: Analysis of a prospective cohort of infants with antenatal ZIKV exposure confirmed by maternal or infant RT-PCR or IgM during the epidemic in Rio de Janeiro, Brazil. Clinical findings before 3 months of age were associated with Bayley-III Scales of Infant and Toddler Development conducted after 6 months of age. RESULTS: ZIKV exposure was confirmed in 219 cases; 162 infants were normocephalic, 53 were microcephalic, 4 had no head circumference recorded because of perinatal death/LTFU. Seven of the 112 normocephalic infants developed secondary microcephaly between 3 weeks and 8 months of age. Among the normocephalic at birth cohort, the mean HCZ among normal, at risk, and developmentally delayed children was significantly different (ANOVA, P = 0.02). In particular, the mean HCZ of the developmentally delayed group was significantly lower than that of the normal group (Tukey's test, P = 0.014). HCZ was more strongly associated with lower expressive language scores (P = 0.04) than receptive language scores (P = 0.06). The rate of auditory abnormalities differed among the normal, at risk, and developmentally delayed groups (Chi-squared test, P = 0.016), which was driven by the significant difference between the normal and at risk groups (post hoc test, P = 0.011, risk ratio 3.94). Auditory abnormalities were associated with both expressive and receptive language delays (P = 0.02 and P = 0.02, respectively). CONCLUSIONS: Clear predictors of neurodevelopment in normocephalic ZIKV-exposed children have not been previously identified. Our findings demonstrate that smaller HCZ and auditory abnormalities in these infants correlate with poor neurodevelopment as toddlers. Language delay is the most prominent developmental concern among these children, who will require frequent auditory and speech evaluations throughout childhood.

Visual Acuity alterations in heavily impaired Congenital Zika Syndrome (CZS) children.

Introduction: This study aimed to assess visual acuity (VA) in Congenital Zika Syndrome (CZS)-children to evaluate visual loss. To that end we evaluated 41 CZS - children, from Rio de Janeiro using Teller Acuity Cards. Methods: To asses VA, we evaluated 41 CZS - children, from Rio de Janeiro using Teller Acuity Cards. The children had Zika virus-infection confirmed by reverse transcription-polymerase chain reaction (RT-PCR) or clinical evaluation. Results: In 39 out of 41 (95%) children, the VA scores were below normative values, while in 10 cases, VA was only marginally below normal; in the remaining 29 cases, VA was more than 0.15 logMAR below the lower limit. There was no correlation between VA and the cognitive domain tasks, although there was a correlation between VA and motor domain tasks. Thirty-seven children performed at least one task in the cognitive set, while fourteen children did not perform any task in the motor set. Children with VA above the lower limit performed better in the cognitive and motor tasks. Discussion: We concluded that ZIKV- infected children with CZS were highly VA impaired which correlated with motor performance, but not with cognitive performance. Part of the children had VA within the normal limits and displayed better performance in the cognitive and motor sets. Therefore, even if heavily impaired, most children had some degree of VA and visual function.

Hearing screening analysis in children exposed to the Zika virus / Análise da triagem auditiva de crianças expostas ao vírus Zika

ABSTRACT Purpose: to analyze the results of neonatal hearing screening examinations in newborns with and without microcephaly, exposed to the Zika virus, without other risk indicators for hearing loss, and verify the association between screening results, sample characteristics, and the gestational trimester when exposure took place. Methods: a descriptive cross-sectional study. Subjects included in the study had no risk indicator for hearing loss other than microcephaly, and presented, along with their mothers, positive RT-PCR results, respectively at birth and during pregnancy. The transient evoked otoacoustic emission and brainstem auditory evoked potential examinations were applied by the researcher between March 2016 and December 2017. Newborns failed the screening when they failed at least one retest in at least one ear. The data were descriptively analyzed, using the Fisher exact test; p-values equal to or lower than 0.05 were considered significant. Results: out of the 45 subjects, 30 (66.7%) were females, 6.7% were likely to have sensorineural hearing loss, with or without auditory neuropathy spectrum disorder - which was possibly present in only one ear of one of these three subjects. Failure in the screening was statistically significant in subjects with at least one of the congenital Zika syndrome characteristics and subjects with subcortical calcification and brain cortex thinning, macular chorioretinal atrophy with focal pigmentary mottling, and hypertonia with symptoms of extrapyramidal involvement. The gestational trimester of exposure was associated with screening results. Conclusion: the responses in screening point to the possibility of hearing loss in newborns with and without microcephaly, whereas the presence of microcephaly was not significant to examination failures. Exposure in the first gestational trimester indicated a possible relationship with screening failures.

RESUMO Objetivo: analisar os resultados dos exames de triagem auditiva neonatal de recém-nascidos sem e com microcefalia expostos ao vírus Zika, que não apresentaram outros indicadores de risco para deficiência auditiva e verificar a associação entre o resultado da triagem, as características da amostra e o trimestre gestacional em que ocorreu a exposição. Métodos: estudo descritivo de corte transversal. Fizeram parte do estudo sujeitos sem indicadores de risco para deficiência auditiva, com exceção da microcefalia, cujas mães apresentaram na gestação o exame RT-PCR positivo e sujeitos que tiveram o RT-PCR positivo, ao nascimento. Os exames de Emissões Otoacústicas Transientes e Potencial Evocado Auditivo de Tronco Encefálico foram aplicados, pela pesquisadora, entre março de 2016 e dezembro de 2017. O recém-nato foi considerado reprovado na triagem quando apresentou falha em pelo menos um reteste, em ao menos uma orelha. Os dados foram analisados de forma descritiva e utilizando-se o teste estatístico exato de Fisher, p valor menor ou igual a 0,05 foi considerado significante. Resultados: dos 45 sujeitos, 30 (66,7%) eram do sexo feminino, 6,7% apresentaram a probabilidade de alteração do tipo sensorioneural, com ou sem espectro da neuropatia auditiva e somente um dentre esses três sujeitos apresentou uma das orelhas com chance do espectro da neuropatia auditiva, isoladamente. A falha na triagem foi estatisticamente significativa, nos sujeitos que apresentavam pelo menos uma característica da Síndrome da Zika Congênita e nos sujeitos com calcificação subcortical com afilamento do córtex cerebral, atrofia coriorretiniana macular com moteado pigmentar focal e hipertonia com sintomas de envolvimento extrapiramidal. Houve associação do trimestre gestacional da exposição com o resultado de triagem. Conclusão: as respostas verificadas pela triagem apontam para a possibilidade de alteração auditiva em recém-nascidos sem e com microcefalia, onde a presença da microcefalia não foi significante para falha nos exames. A exposição no primeiro trimestre gestacional indicou uma possível relação com falhas na triagem.

Brazilian guidelines on the frequency of ophthalmic assessment and recommended examinations in healthy children younger than 5 years / Diretrizes brasileiras sobre avaliação oftalmológica de crianças saudáveis menores de 5 anos: exames recomendados e frequência

ABSTRACT Purpose: To provide guidance on the frequency and components of eye examinations for healthy children aged 0 to 5 years. Methods: These guidelines were developed based on the medical literature and clinical experience of an expert committee. PubMed/Medline searches were performed, with selected publications not restricted to systematic reviews, randomized controlled trials, or observational studies. The Grading of Recommendations Assessment, Development, and Evaluation profile was applied when suitable, and for issues without scientific evidence, recommendations were based on expert consensus. Recommendations by the American Academy of Pediatrics, American Association of Pediatric Ophthalmology and Strabismus, American Academy of Ophthalmology, Royal College of Ophthalmologists, and Canadian Ophthalmological Society were also reviewed. The final guideline document was approved by the Brazilian Pediatric Ophthalmology Society and by the Brazilian Pediatric Society. Results: Newborns must undergo the red reflex test and inspection of the eyes and adnexa by a pediatrician within 72 hours of life. The red reflex test should be repeated by the pediatrician during childcare consultations at least three times per year during the first 3 years of life. If feasible, a comprehensive ophthalmologic examination may be performed between 6 and 12 months of age. Until 36 months of age, the pediatrician should assess the infant's visual development milestones, age-appropriate assessment of visual function, ocular fixation, and eye alignment. At least one comprehensive ophthalmologic examination should be performed at 3 to 5 years of age. The examination should minimally include inspection of the eyes and adnexa, age-appropriate visual function assessment, evaluations of ocular motility and alignment (cover tests), cycloplegic refraction, and dilated fundus. Conclusions: Guidelines concerning the frequency of ophthalmic assessment are important tools for directing physicians regarding best practices that avoid treatable vision problems that affect children's development, school, and social performance and cause unnecessary permanent vision loss.

RESUMO Objetivo: Fornecer orientações sobre a frequência e os componentes dos exames oftalmológicos para crianças saudáveis de 0 a 5 anos. Métodos: Essas diretrizes foram desenvolvidas com base em revisão bibliográfica e experiência clínica de um comitê de especialistas. Foram realizadas buscas PubMed/Medline; documentos selecionados não se restringiram a revisões sistemáticas, ensaios clínicos randomizados e estudos observacionais. Quando adequado, o perfil GRADE foi aplicado para graduá-los e o consenso de especialistas foi usado nos tópicos sem evidência científica. Também foram revisadas as recomendações pela Academia Americana de Pediatria, Associação Americana de Oftalmologia Pediátrica e Estrabismo, Academia Americana de Oftalmologia, Royal College of Ophthalmologist e Sociedade Canadense de Oftalmologia. O documento final foi aprovado pela Sociedade Brasileira de Oftalmologia Pediátrica e Sociedade Brasileira de Pediatria. Resultados: Os recém-nascidos devem ser submetidos ao teste do reflexo vermelho e inspeção dos olhos e anexos pelo pediatra dentro de 72 horas de vida ou antes da alta da maternidade. O teste do reflexo vermelho deve ser repetido pelo pediatra durante as consultas de puericultura pelo menos três vezes ao ano durante os primeiros 3 anos de vida. Se factível, um exame oftalmológico completo pode ser feito entre 6 a 12 meses de vida. Até os 36 meses de idade, os marcos visuais, função visual apropriada para a idade, fixação e alinhamento ocular também devem ser avaliados pelo pediatra ou médico da família. Pelo menos um exame oftalmológico completo deve ser realizados entre 3 e 5 anos de idade. O exame deve conter pelo menos inspeção dos olhos e anexos, avaliação da função visual apropriada para a idade, avaliação da motilidade e alinhamento ocular (testes de cobertura), refração sob cicloplegia e avaliação do fundo de olho dilatado. Conclusões: As diretrizes sobre a frequência da avaliação oftalmológica são ferramentas importantes para orientar os médicos sobre a melhor prática a fim de evitar problemas visuais tratáveis na infância, que poderiam comprometer seu desenvolvimento social, escolar e global, além de causar perda permanente da visão.
