Estado nutricional de crianças com microcefalia congênita transmitida pelo vírus Zika / Nutritional status of children with congenital microcephaly transmitted by Zika Virus / Estado nutricional de niños con microcefalia congénita transmitida por el Virus Zika

A microcefalia é uma condição sem tratamento causa alterações de cunho sensorial, cognitivo, motor, auditivo e visual, podendo ser adquirida por meio da infecção congênita pelo vírus Zika. O objetivo desta pesquisa foi avaliar o estado nutricional, o consumo alimentar e os fatores socioeconômicos que implicam na alimentação das crianças com microcefalia oriunda da infecção pelo Zika Vírus. Este estudo é uma pesquisa de campo descritiva, de delineamento transversal, que foi realizada com dez crianças na faixa etária de 2 a 3 anos. O estado nutricional foi avaliado utilizando balança digital e fita métrica, e os questionários sobre o consumo alimentar e condições socioeconômicas foram respondidos pelos cuidadores das crianças. Os resultados encontrados apresentaram inadequações das seguintes maneiras: 60% na estatura por idade, 50% no peso por idade e 40% no peso por estatura. Sobre a alimentação, 70% tinham uma alimentação inadequada e 60% apresentavam condições socioeconômicas de risco. Perante os achados, é possível interligar os fatores pesquisados com um retardo no desenvolvimento infantil. Portanto, ressalta-se que a microcefalia associada à alimentação inadequada e baixa condição social é capaz de agravar o estado nutricional.

Microcephaly is an untreated condition that leads to sensory, cognitive, motor, auditory and visual changes and can be acquired through congenital infection by the Zika Virus. Hence, this study evaluates the nutritional status, food consumption and socioeconomic factors that affect the nutrition of children with microcephaly transmitted by Zika Virus infection. A descriptive, cross-sectional field research was conducted with ten children aged 2 to 3 years. Nutritional status was assessed using a digital scale and measuring tape. Questionnaires on food consumption and socioeconomic conditions were answered by the children's caregivers. The results found presented the following inadequacies: 60% in height for age, 50% in weight for age, and 40% in weight for height. Regarding nutrition, 70% of the children had inadequate nutrition and 60% lived under risky socioeconomic conditions. Given these findings, the factors researched can be linked with a delay in child development. Therefore, microcephaly associated with inadequate nutrition and low social status can worsen nutritional status.

La microcefalia es una afección no tratada que conlleva cambios sensoriales, cognitivos, motores, auditivos y visuales, y puede adquirirse a través de una infección congénita por el virus Zika. El objetivo de este estudio fue evaluar el estado nutricional, el consumo de alimentos y los factores socioeconómicos que afectan la nutrición de niños con microcefalia provocada por la infección por el virus Zika. Se trata de un estudio descriptivo, de enfoque transversal, que se realizó con 10 niños de entre 2 y 3 años. El estado nutricional se evaluó mediante una balanza digital y una cinta métrica, y los cuidadores de los niños respondieron cuestionarios sobre consumo de alimentos y condiciones socioeconómicas. Los resultados encontrados presentaron insuficiencias en los siguientes aspectos: 60% en talla para la edad, 50% en peso para la edad y 40% en peso para la talla. En cuanto a la nutrición, el 70% tenía una nutrición inadecuada y el 60% tenía condiciones socioeconómicas de riesgo. Teniendo en cuenta los hallazgos, es posible relacionar los factores investigados con un retraso en el desarrollo infantil. Por tanto, cabe destacar que la microcefalia asociada a una nutrición inadecuada y un bajo estatus social es capaz de empeorar el estado nutricional.

Arboviruses epidemic associates with Guillain-Barré syndrome: temporal series in northeast Brazil / Epidemia de arboviroses associada à síndrome de Guillain-Barré: série temporal no nordeste brasileiro / Epidemia de arbovirosis asociada al síndrome de Guillain-Barré: serie temporal en el noreste de Brasil

Arboviruses cause public health problems in several countries, and records show that they can generate central and peripheral neurological complications with permanent sequelae. However, it is not certain which arbovirus is responsible for outbreaks of the Guillain-Barré Syndrome (GBS), especially in Brazil. Thus, the objective of this study is to verify if there is a coincidence between the GBS outbreak and the most common arboviruses in Northeastern Brazil, as well as their relationship. An ecological time series study was designed with the federative units of Northeastern Brazil, using hospitalizations for Guillain-Barré syndrome and notifications of arbovirus infections between 2014 and 2019 as a data source. Distribution incidence curves were constructed for the conditions studied, and generalized estimating equations (GEE) models were applied to estimate the relationship between arboviruses and Guillain-Barré. The results showed a similar distribution for the incidences of Chikungunya virus (z=7.82; p=0.001), Zika virus (z=3.69; p=0.03), and Guillain-Barré syndrome (z=2.98; p=0.05) from 2014 to 2019. The GEE model revealed that the distribution of Chikungunya incidence is associated with the distribution of GBS incidence in each year (x2Wald=3,969; p=0.046). This pattern was repeated in seven of the nine states, while the Zika virus had a significant relationship with GBS in only two states. The outbreak of GBS in Northeastern Brazil appears to be probabilistically related to outbreaks of the Chikungunya virus.

As arboviroses são problemas de saúde pública em vários países e há registros de que podem produzir complicações neurológicas centrais e periféricas com sequelas permanentes. Entretanto, não se sabe ao certo qual delas é realmente responsável pelos surtos da Síndrome de Guillain-Barré (SGB), principalmente no Brasil. Assim, o objetivo é verificar se há coincidência entre o surto de SGB e as arboviroses mais comuns no Nordeste do Brasil e suas relações. Foi desenhado um estudo ecológico de série temporal com as unidades federativas do Nordeste do Brasil, adotando como fonte de dados as internações Guillain-Barré e as notificações de infecções por arbovírus entre 2014 e 2019. Curvas de distribuição de incidência foram construídas para as condições estudadas, e foram aplicados modelos de equações generalizadas estimadas (GEE) para estimar a relação entre arbovírus e Guillain-Barré. Evidencia-se que há distribuição semelhante para as incidências do vírus Chikungunya (z=7,82; p=0,001), vírus Zika (z=3,69; p=0,03) e síndrome de Guillain-Barré (z=2,98; p=0,05) entre 2014 e 2019. O modelo GEE revelou que a distribuição da incidência de Chikungunya está associada à distribuição da incidência de SGB em cada ano (x2Wald=3,969; p=0,046). Esse padrão se repetiu em sete dos nove estados, enquanto o zika vírus teve uma relação significativa com o GBS em apenas dois estados. Conclui-se, então, que o surto de SGB no Nordeste do Brasil parece estar probabilisticamente relacionado aos surtos do vírus Chikungunya.

Los arbovirus causan problemas de salud pública en varios países y, según indican los reportes, pueden producir complicaciones neurológicas centrales y periféricas con secuelas permanentes. Sin embargo, no se sabe cuál de ellos es realmente el responsable de los brotes del síndrome de Guillain-Barré (SGB), especialmente en Brasil. Así, el objetivo de este estudio es verificar si existen coincidencias entre el brote del SGB y los arbovirus más comunes en el Noreste de Brasil y sus asociaciones. Se diseñó un estudio de series temporales ecológico en las unidades federativas del Noreste de Brasil, adoptando como fuente de datos las hospitalizaciones y las notificaciones de arbovirosis de Guillain-Barré entre 2014 y 2019. Se construyeron curvas de distribución de incidencia para las condiciones científicas, y se aplicó una ecuación estimada generalizada (GEE) para estimar la relación entre arbovirus y Guillain-Barré. Se encontró que existe una distribución similar en las incidencias de virus del chikunguña (z=7,82; p=0,001), virus del Zika (z=3,69; p=0,03) y síndrome de Guillain-Barré (z =2,98; p=0,05) entre 2014 y 2019. El modelo GEE reveló que la distribución de la incidencia de chikunguña está asociada con la distribución de la incidencia de SGB en cada año (x2Wald=3,969; p=0,046). Este patrón se repitió en siete de los nueve estados, mientras que el virus del Zika presentó una relación significativa con el SGB en solo dos estados. El brote del SGB en el Noreste de Brasil parece estar relacionado probabilísticamente con los brotes del virus del chikunguña.

Does a patient with acquired arbovirus infection have a hearing impairment? A scoping review of hearing changes in an adult with Dengue, Chikungunya, and Zika

Abstract Objectives To identify and understand the evidence regarding hearing changes related to acquired Dengue, Chikungunya, and Zika virus infection in adult individuals. Methods A scoping review was performed according to the recommendations of The Joanna Briggs Institute and guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews in the Embase, PubMed/Medline, ScienceDirect, Scopus, and Web of Science databases without restriction on language and year of publication. Case studies, observational studies, and clinical trials reporting hearing loss in adult subjects (>18-60 years of age) of both sexes with DENV, CHIKV, or ZIKV diagnosed by positive molecular/serological examination by RT-PCR or IgM/IgG by ELISA method were included. Results Thirteen studies met the inclusion criteria and were selected for review. The occurrence of auditory symptoms caused by arboviroses and the presence of permanent or transient sensorineural hearing loss was variable in adults. Conclusions Dengue, Chikungunya, and Zika infections in adults are associated with a variety of auditory symptoms. The frequency of permanent or transient sensorineural hearing loss is low but not negligible.

Encoding of speech sounds with frequency-following response in infants with Congenital Zika Syndrome: A case-controlled study

ABSTRACT Purpose: to investigate the frequency-following response (FFR) for sustained neural activity. Methods: 39 individuals, aged between 20 to 47 months old were divided into 2 groups: (i) 20 individuals without prenatal exposure to the congenital Zika syndrome (CZS) or hydrocephaly, normal development, no risk factors for hearing loss or syndromic hearing impairment and (ii) 19 individuals diagnosed with CZS and microcephaly - based on imaging studies linked to the clinical presentation of the condition. All participants exhibited normal click-ABR tests. FFR waveforms were documented using the /da/ syllable employing the Navigator Pro. The statistical analysis used was ANOVA (p-value <0.05). Results: no distinctions were observed concerning the variables of group, age, or gender with respect to FFR latency values, except for an interaction between gender and group for latency values associated with waves V and F. Children with CZS and microcephaly showed a difference for latency values in wave V for both males and females, when compared to the control group. Conclusion: children presented with CZS and microcephaly showed higher average latencies for waves V, A, C, D and F (male) compared to the control group, whereas, in waves E, F (female) and O they showed higher values in the control group.

Oral conditions of children with microcephaly associated with congenital Zika syndrome: a cross-sectional study

Abstract The aim of the present study was to compare the oral conditions of children with congenital Zika syndrome (CZS)-associated microcephaly, non-CZS-associated microcephaly, and normotypical children, as well as to characterize their sociodemographic aspects and medical history. A paired cross-sectional study was carried out on 14 children with CZS-associated microcephaly and 24 age-matched controls, in Belo Horizonte, in southeastern Brazil. Children's oral conditions were assessed: dental caries experience (dmft/DMFT indices); developmental defects of enamel (DDE) index; dental anomalies; mucosal changes; lip sealing, and malocclusion (overjet, overbite, and/or posterior crossbite alterations). The quality of oral hygiene was analyzed by the simplified oral hygiene index. The children's mothers also answered a questionnaire about sociodemographic and medical history data. The variables were analyzed descriptively. Female participants were more prevalent (60.5%), and the mean age of the participants was 4.9 years (±1.4) (range: 2-8 years) and 92.1% of their exhibited some oral condition. All participants with CZS-associated microcephaly showed absence of lip sealing and had malocclusion (100.0%). When compared to the other groups, children with CZS had a higher percentage of dental anomalies (35.7%), mucosal changes (71.4%), and unsatisfactory oral hygiene (64.3%). In a sample composed mainly of female participants aged less than 5 years, the prevalence of oral conditions and unsatisfactory oral hygiene was higher in the group with CZS-associated microcephaly, followed by the group with non-CZS-associated microcephaly. Normotypical children had the highest percentage of dental caries experience.

Evaluation of the quality of prenatal care in Colombia during the 2016 Zika outbreak in endemic and non-endemic areas

Objetive: To evaluate the quality of prenatal care during the outbreak of Zika virus infection in endemic and non-endemic vector-borne regions in Colombia. Materials and methods: A descriptive study of prenatal care supplemented by interviews to explore personal experiences during the epidemic. A total of 40 pregnant women in endemic areas and 44 in nonendemic areas participated. Information collected included previous pregnancies, reasons for starting prenatal care, information about Zika, prenatal care (activities of doctors, nurses, laboratories, and images), and perceptions of quality. Then, 8 interviews were conducted with pregnant women diagnosed with Zika. Questioned about knowledge of Zika and the quality of medical care services. Results: Problems with laboratories and diagnostic images were found in both regions and dehumanizing treatment in the endemic region. Women from the endemic region received news and communications about the effects of Zika during pregnancy, causing anxiety and fear among some women. The quality of health care was not what the women expected and they thought they would receive more care from doctors and nurses. Discussion: Our findings show deficiencies in education provided in health institutions. The experience during prenatal control in the endemic regions was imprecise and the information came from other sources, different from the health sector. Adittionally, support and follow-up was deficient as well. It's possible that health professionals have few knowledge about information management, which generated confusion, fear and uncertainty among the pregnant women about the adverse effects on the newborns. Conclusions: Findings suggest deficiencies in the technical quality of the prenatal care provided, particularly in the region that was endemic for vector-borne diseases. Reproductive health services and the technical quality of prenatal care need to be strengthened, especially during a sanitary crisis.

Objetivo: Evaluar la calidad de la atención prenatal durante la epidemia de Zika en regiones endémicas y no endémicas de infecciones trasmitidas por vectores en Colombia. Materiales y Métodos: Estudio descriptivo de la atención prenatal complementado con entrevistas, con el fin de explorar experiencias personales durante la epidemia. Participaron 40 gestantes en zona endémica y 44 en no endémicas. La información recolectada incluyó embarazos previos, razones para iniciar control prenatal, información sobre Zika, control prenatal (actividades de médicos, enfermeras, laboratorios e imágenes) y percepción de calidad. Luego se realizaron 8 entrevistas a gestantes con diagnóstico de Zika. Se interrogó sobre conocimiento del Zika y calidad de los servicios de atención médica. Resultados: Se encontraron problemas con laboratorios e imágenes diagnósticas en ambas regiones y trato deshumanizado en la región endémica. Las gestantes en la región endémica recibieron noticias y comunicados sobre los efectos de Zika durante el embarazo, lo que causó ansiedad y miedo en algunas mujeres. La calidad de la atención medica no era la deseada y pensaron que recibirían mejor atención de médicos y enfermeras. Discusión: Nuestros hallazgos demuestran educación deficiente en las instituciones de salud. La experiencia durante el control prenatal en las regiones endémicas fue imprecisa y venía de fuentes diferentes al sector salud. Además, el soporte y seguimiento fue deficiente. Es probable que el personal de salud tenga poco conocimiento sobre cómo manejar la información, lo cual generó confusión, miedo e incertidumbre entre las gestantes sobre los efectos adversos en los bebes. Conclusiones: Los hallazgos sugieren deficiencia en la calidad técnica de la atención prenatal, particularmente en la región endémica. Es necesario fortalecer los servicios de salud reproductiva y la calidad técnica de la atención prenatal, especialmente durante crisis sanitaria.

Review of dengue, zika and chikungunya infections in nervous system in endemic areas / Revisão da infecção por dengue, zika e chikungunya no sistema nervoso em áreas endêmicas

Abstract Dengue, zika, and chikungunya are arboviruses of great epidemiological relevance worldwide. The emergence and re-emergence of viral infections transmitted by mosquitoes constitute a serious human public health problem. The neurological manifestations caused by these viruses have a high potential for death or sequelae. The complications that occur in the nervous system associated with arboviruses can be a challenge for diagnosis and treatment. In endemic areas, suspected cases should include acute encephalitis, myelitis, encephalomyelitis, polyradiculoneuritis, and/or other syndromes of the central or peripheral nervous system, in the absence of a known explanation. The confirmation diagnosis is based on viral (isolation or RT-PCR) or antigens detection in tissues, blood, cerebrospinal fluid, or other body fluids, increase in IgG antibody titers between paired serum samples, specific IgM antibody in cerebrospinal fluid and serological conversion to IgM between paired serum samples (non-reactive in the acute phase and reactive in the convalescent). The cerebrospinal fluid examination can demonstrate: 1. etiological agent; 2. inflammatory reaction or protein-cytological dissociation depending on the neurological condition; 3. specific IgM, 4. intrathecal synthesis of specific IgG (dengue and chikungunya); 5. exclusion of other infectious agents. The treatment of neurological complications aims to improve the symptoms, while the vaccine represents the great hope for the control and prevention of neuroinvasive arboviruses. This narrative review summarizes the updated epidemiology, general features, neuropathogenesis, and neurological manifestations associated with dengue, zika, and chikungunya infection.

Resumo Dengue, zika e chikungunya são arboviroses de grande relevância epidemiológica em todo o mundo. A emergência e reemergência dessas infecções virais transmitidas por mosquitos constituem um grave problema de saúde pública humana. As manifestações neurológicas causadas por esses vírus têm alto potencial de morte ou sequelas. As complicações que ocorrem no sistema nervoso associadas às arboviroses podem representar um desafio diagnóstico e de tratamento. Em áreas endêmicas, casos suspeitos devem incluir encefalite, mielite, encefalomielite, polirradiculoneurite e/ou outras síndromes do sistema nervoso central ou periférico, na ausência de explicação conhecida. Caso confirmado de arbovirose neuroinvasivo é baseado na detecção viral (isolamento ou RT-PCR) ou de antígenos em tecidos, sangue, líquido cefalorraquidiano ou outros fluidos corporais, aumento dos títulos de anticorpos IgG entre amostras de soro pareadas, anticorpo IgM específico no líquido cefalorraquidiano e conversão sorológica para IgM entre amostras de soro pareadas. O exame do líquido cefalorraquidiano pode demonstrar: 1. agente etiológico; 2. reação inflamatória ou dissociação proteico-citológica, dependendo do quadro neurológico; 3. valor absoluto de IgM específica; 4. síntese intratecal de anticorpos IgG específicos (dengue e chikungunya); 5. exclusão de outros agentes infecciosos. O tratamento das complicações neurológicas visa melhorar os sintomas, enquanto a vacina representa a grande esperança para o controle e a prevenção das arboviroses neuroinvasivas. Esta revisão narrativa resume a atualização da epidemiologia, características gerais, neuropatogênese e manifestações neurológicas associadas à infecção pelos vírus da dengue, zika e chikungunya.

Desarrollo y validación de un método de suspensión basado en células Vero para la detección del virus Zika / Development and validation of a vero cell-based suspension method for the detection of Zika virus

Objetivo . Desarrollar y validar un método de suspensión celular utilizando células Vero 76 para el cultivo del virus Zika (ZIKV) basado en la infección de células recién sembradas no adheridas. Material y métodos . Se utilizaron tres multiplicidades de infección diferentes del ZIKV para desarrollar y comparar este novedoso método con el método estándar de monocapa de células confluentes. Además, validamos preliminarmente el método de suspensión utilizando muestras clínicas caracterizadas como positivas o negativas para el ZIKV. El método estándar de monocapa se utilizó como método de referencia, y el aislamiento viral se confirmó mediante un RT-PCR específico del ZIKV. Se estimó la sensibilidad e intervalos de confianza del 95% para el método de suspensión. Asimismo, se realizó una comparación técnica del método de suspensión contra el método de monocapa. Resultados . Nuestros hallazgos sugieren que tanto la carga viral como la replicación del ZIKV fueron comparables entre los métodos de infección en monocapa y en suspensión. Aunque ambos métodos fueron adecuados para cultivar y aislar el ZIKV, el método de suspensión se caracterizó por ser más fácil, barato y rápido, así como una técnica de aislamiento sensible. En comparación con el método de monocapa, el método de suspensión fue cuatro veces más sensible en la detección del ZIKV en casos inconclusos por RT-PCR. Conclusiones . El método de suspensión tiene el potencial de ser un método eficaz para cultivar y aislar el ZIKV y su uso es potencialmente útil tanto en la investigación como en entornos clínicos.

Objective. To develop and validate a cell suspension method using Vero 76 cells for culturing Zika virus (ZIKV) based on infection of detached freshly seeded cells. Material and methods. Three different multiplicities of infection of ZIKV were used to develop and compare this novel method to the standard confluent cell monolayer method. In addition, we preliminary validated the cell suspension method using well-characterized ZIKV positive and negative clinical samples. The standard confluent cell monolayer method was used as the reference method, and viral isolation was confirmed by a ZIKV-specific RT-PCR. The sensitivity and its 95% confidence intervals for the cell suspension method were estimated. Also, a technical comparison of the cell suspension method against the cell monolayer method was performed. Results. Our findings suggested that both the viral load and replication of ZIKV were comparable between both monolayer- and suspension-infection methods. Although both methods were suitable for culturing and isolating ZIKV, the cell suspension method was easier, cheaper, and quicker as well as a sensitive isolation technique. The cell suspension method was significantly more sensitive in detecting Zika in inconclusive cases by RT-PCR, with a fourfold increase compared to the confluent cell monolayer method. Conclusion. The cell suspension method has the potential to be an effective method for cultivating and isolating ZIKV and its application is potentially useful in both research and clinical settings.

Participaron 30 niños con una media de edad al momento de la evaluación de 37,5 (RIC: 35,7-39,2) meses. Se halló una edad equivalente en meses en las áreas: motora 25,8 (DE: 7,8), adaptativa 26,7 (DE: 5,8), comunicativa 30,2 (DE: 6,9), personal social 33,5 (DE: 8,3) y cognitiva 35,6 (DE: 5,9). Los niños presentaron retraso en el desarrollo para la edad cronológica, 25 niños presentaban retraso en una de las cinco áreas evaluadas. Una alta proporción de niños expuestos al virus del Zika durante la gestación presentaron retraso en el desarrollo, principalmente en el dominio adaptativo y motor.

Zika virus infection affects the development of the nervous system. This study describes the cognitive, adaptative, communicative, social and motor neurodevelopment of children exposed to Zika virus in utero. We used the Batelle scale to assess neurodevelopment three years after birth. Thirty children were included, who had a mean age at evaluation of 37.5 (IQR: 35.7-39.2) months. We found the following equivalent ages in months for each area: motor 25.8 (SD: 7.8), adaptive 26.7 (SD: 5.8), communicative 30.2 (SD: 6.9), social personal 33.5 (SD: 8.3) and cognitive 35.6 (SD: 5.9). Children showed development delay for their chronological age, 25 children were delayed in one of the five areas assessed. A high rate of children exposed to Zika virus during gestation presented delayed developmental age, mainly regarding the adaptive and motor areas.

Introducción. El desarrollo de la resistencia a insecticidas de Aedes aegypti representa una gran amenaza para la salud pública. La vigilancia y el monitoreo de la eficacia biológica a los insecticidas y la sensibilidad de las poblaciones de Aedes aegypti es de fundamental importancia para prolongar la vida útil de estas moléculas. Objetivo. Evaluar la eficacia biológica de los insecticidas deltametrina y ciflutrina y la sensibilidad de poblaciones de Aedes aegypti a estos insecticidas durante el brote epidémico de virus del Zika en Kuna Yala, Panamá. Materiales y métodos. Se evaluó la eficacia biológica de la deltametrina y la ciflutrina, y la sensibilidad a estos insecticidas de poblaciones de la cepa Aedes aegypti Ustupo, mediante bioensayos estandarizados por la Organización Mundial de la Salud durante el brote epidémico de virus del Zika en Kuna Yala, Panamá. Resultados. En los bioensayos con Aedes aegypti Ustupo se observó posible resistencia a deltametrina y a ciflutrina con un porcentaje de mortalidad del 95,3 y 94 %, respectivamente. Se registró baja eficacia biológica con la cepa Aedes aegypti Ustupo para la deltametrina y la ciflutrina, con medias de porcentajes de mortalidad de 75 y 31,1 %, en el intradomicilio, mientras que en el peridomicilio fue de 63,7 y 26,1 %, respectivamente. Conclusión. Los resultados de este estudio representan un desafío que debe enfrentar el Programa Nacional de Control de Aedes para lograr cuidar y mantener el efecto tóxico de los insecticidas aplicados contra las poblaciones de Aedes. Es necesario que el Programa Nacional de Control de Aedes establezca unos lineamientos de manejo de la resistencia para caracterizarla y evaluar la distribución geográfica de las poblaciones afectadas. Lo anterior con el propósito de garantizar la sostenibilidad de las intervenciones antivectoriales contra las poblaciones de Aedes.

Introduction. The development of resistance to insecticides in Aedes aegypti represents a major threat to public health. Surveillance and monitoring of the biological efficacy and sensibility of Aedes aegypti populations to insecticides is fundamental to prolong the useful life of insecticide molecules. Objective. To evaluate the biological efficacy of deltamethrin and cyfluthrin and sensibility to insecticides in Aedes aegypti during the zika epidemic outbreak in Kuna Yala, Panama. Materials and methods. We assessed the biological efficacy of deltamethrin and cyfluthrin, and sensibility in the strain Aedes aegypti Ustupo using bioassays standardized by the World Health Organization during the Zika epidemic outbreak in Kuna Yala, Panama. Results. In the bioassays with Aedes aegypti Ustupo, we observed a possible resistance to deltamethrin and cyfluthrin with a mortality rate of 95,3 and 94%, respectively. The obtained results registered low biological efficacy of deltamethrin and cyfluthrin with average percentages of mortality of 75 and 31.1% in the intradomicile, and 63,7 and 26.1% in the peridomicile. Conclusion. The results of this study represent a challenge for the National Aedes Control Program to care for and maintain the toxic effect of insecticides applied against Aedes populations. There is a need for the National Aedes Control Program to establish some guidelines about resistance assessment and resistant populations' geographic distribution to guarantee the sustainability of anti-vector interventions against Aedes populations.

Síndrome congênita do zika e impactos para as famílias: uma revisão integrativa / Congenital zika syndrome and family impacts: an integrative review

Resumo Em 2015, um espectro de anomalias congênitas, incluindo microcefalia, acometeu recém-nascidos como resultado da transmissão vertical pelo vírus zika, posteriormente denominada síndrome congênita do zika (SCZ). Desde então, cerca de 4 mil crianças foram afetadas em 27 países, sendo o Brasil o mais atingido. Cuidadores familiares também têm sido impactados. Esse estudo analisa publicações científicas que investigam as maneiras como a doença afetou as dinâmicas de vida de cuidadores familiares de crianças com SCZ. Realizou-se uma revisão integrativa de literatura consultando as bases de dados PubMed, Biblioteca Virtual em Saúde e Embase. Após as etapas de triagem, foram identificados 31 artigos. Os principais resultados foram agrupados em quatro categorias: a) impactos sociais que evidenciaram mudanças nas relações familiares, nos projetos de vida e no convívio social; b) impactos subjetivos - sentimentos de resiliência, solidão, luto, sobrecarga, medo, incerteza e relação com a espiritualidade; c) impactos econômicos e materiais - perda de renda, aumento de despesas, mudança de moradia e desemprego e d) impactos na saúde - despreparo dos serviços, renúncia do cuidado de si, modificações dos padrões nutricionais e de sono, repercussão para a saúde mental e níveis de estresse, ansiedade e depressão.

Abstract In 2015, a range of congenital anomalies resulting from mother-to-child transmission of the zika virus emerged. Later called congenital zika syndrome (CZS), the condition includes microcephaly. Since then, around 4,000 children have been affected in 27 countries, with Brazil accounting for the largest proportion of cases. Family caregivers have also been affected. This study analyzes the literature on caregivers of children with CZS and how the disease has affected their everyday lives. We conducted an integrative review using the PubMed, Virtual Health Library, and Embase databases. Thirty-one articles were identified for analysis after screening. The findings were grouped into four categories: a) social impacts - changes in family relationships, life projects, and social life; b) subjective impacts - feelings of resilience, loneliness, grief, overburdening, fear, uncertainty, and spirituality and religion; c) economic and material impacts - loss of income, increased household expenses, change of residence, and unemployment; and d) health impacts - service unpreparedness, selflessness, self-care, changes in nutritional and sleep patterns, and mental health problems, including stress, anxiety and depression.

Molecular mimicry between Zika virus and central nervous system inflammatory demyelinating disorders: the role of NS5 Zika virus epitope and PLP autoantigens / Mimetismo molecular entre o vírus Zika e os distúrbios inflamatórios desmielinizantes do sistema nervoso central: o papel do epítopo NS5 do vírus Zika e dos autoantígenos PLP

Abstract Background Evidence indicates a strong link between Zika virus (ZikV) and neurological complications. Acute myelitis, optic neuritis, polyneuropathy, and encephalomyelitis that mimic inflammatory idiopathic demyelination disorders (HDD) after ZikV infection have been reported in Brazil. Objective The present study aims to investigate the possible occurrence of molecular mimicry between ZikV antigens and Multiple Sclerosis (MS) autoantigens, the most frequent HDD of the central nervous system (CNS). Methods A retrospective cohort study with 305 patients admitted due to suspected arbovirus infection in Rio de Janeiro was performed, all subjects were submitted to neurological examination, and a biological sample was collected for serologic and molecular diagnostic. Bioinformatics tools were used to analyze the peptides shared between ZikV antigens and MS autoantigens. Results Of 305 patients, twenty-six were positive for ZikV and 4 presented IDD patterns found in MS cases. Sequence homology comparisons by bioinformatics approach between NS5 ZikV and PLP MS protein revealed a homology of 5/6 consecutive amino acids (CSSVPV/CSAVPV) with 83% identity, deducing a molecular mimicry. Analysis of the 3D structures revealed a similar conformation with alpha helix presentation. Conclusions Molecular mimicry between NS5 Zika virus antigen and PLP MS autoantigens emerge as a possible mechanism for IDD spectrum in genetically susceptible individuals.

Resumo Antecedentes Evidências indicam uma forte ligação entre o vírus Zika (ZikV) e complicações neurológicas. Mielite aguda, neurite óptica, polineuropatia e encefalomielite que mimetizam distúrbios inflamatórios de desmielinização idiopáticos (DDII) após infecção por ZikV têm sido relatadas no Brasil. Obejtivo O presente estudo tem como objetivo investigar a possível ocorrência de mimetismo molecular entre antígenos do ZikV e autoantígenos da Esclerose Múltipla (EM), a DDII mais frequente do sistema nervoso central (SNC). Métodos Foi realizado um estudo de coorte retrospectivo com 305 pacientes internados por suspeita de infecção por arbovirus no Rio de Janeiro, todos os indivíduos foram submetidos a exame neurológico e coleta de amostra biológica para diagnóstico sorológico e molecular. Ferramentas de bioinformática foram usadas para analisar os peptídeos compartilhados entre antígenos do ZikV e autoantígenos da EM. Resultados Dos 305 pacientes, vinte e seis foram positivos para ZikV e 4 apresentaram padrão IDD encontrado em casos de EM. As comparações de homologia de sequência por abordagem de bioinformática entre a proteína NS5 ZikV e PLP EM revelaram uma homologia de 5/6 aminoácidos consecutivos (CSSVPV/CSAVPV) com 83% de identidade, deduzindo um mimetismo molecular. A análise das estruturas 3D revelou uma conformação semelhante com apresentação em alfa-hélice. Conclusões O mimetismo molecular entre o antígeno NS5 do vírus Zika e o autoantígeno PLP da EM surge como um possível mecanismo para o espectro IDD em indivíduos geneticamente suscetíveis.

Presentamos el caso de un varón joven con fiebre chikungunya en fase subaguda la cual se presentó al ingreso hospitalario como fiebre de origen desconocido.

Chikungunya fever is a viral disease first described in 1952. Sporadic outbreaks of chikungunya fever are currently reported nationwide (April 2022). We present the case of a young man with chikungunya fever in the subacute phase which presented at hospital admission as fever of unknown origin.

Congenital Zika syndrome / Síndrome congénito por virus Zika

Abstract In February 2016, the World Health Organization declared Zika virus (ZIKV) infection a public health emergency of international concern because it caused congenital Zika syndrome (CZS). The CZS is considered a specific pattern of birth defects caused by ZIKV infection, which is transmitted by the bite of the Aedes aegypti mosquito. The CZS clinical manifestations are broad and nonspecific, including microcephaly, subcortical calcifications, ocular alterations, congenital contractures, early hypertonia, and pyramidal as well as extrapyramidal symptoms. The ZIKV has gained great importance because it has affected a large percentage of the population worldwide during the last few years, despite the measures implemented by international organizations. The pathophysiology and non-vectorial transmission routes of the virus are still under study. The diagnosis is made upon suspicion of ZIKV infection, the patient's clinical manifestations, and it is confirmed by molecular laboratory tests demonstrating the presence of viral particles. Unfortunately, there is no specific treatment or vaccine for this condition; however, patients receive multidisciplinary care and constant monitoring. Therefore, the strategies that have been implemented are directed toward preventive measures and vector control.

Resumen En febrero de 2016, la Organización Mundial de la Salud declaró a la infección por virus Zika una emergencia de salud pública de importancia internacional por ser la causa del síndrome congénito por virus Zika. Este síndrome es considerado un patrón específico de defectos al nacimiento causados por la infección por virus Zika, que se transmite por la picadura del mosquito vector Aedes aegypti y cuyas manifestaciones clínicas son amplias e inespecíficas, entre las que destacan microcefalia, calcificaciones subcorticales, alteraciones oculares, contracturas congénitas, hipertonía temprana y síntomas de afectación piramidal y extrapiramidal. Este virus ha tomado gran importancia debido a que durante los últimos años ha afectado a un gran porcentaje de la población en todo el mundo, a pesar de las medidas implementadas por organizaciones internacionales. La fisiopatología y las vías de transmisión no vectorial de la infección aún siguen en estudio. El diagnóstico se realiza ante la sospecha por las manifestaciones clínicas del paciente, y se confirma mediante pruebas moleculares de laboratorio en las que se demuestre la presencia de partículas virales. Desafortunadamente, no existe aún un tratamiento ni una vacuna específica para este padecimiento; sin embargo, los pacientes reciben cuidados multidisciplinarios y monitorización constante. Las estrategias que se han implementado se dirigen hacia medidas preventivas de la infección y el control de los vectores.

Síndrome Congénito del ZIKA y su relación con la pérdida auditiva en infantes: Una revisión de la literatura / Congenital ZIKA syndrome and its relationship to hearing loss in infants: A review of literature

Introducción: Los niños con microcefalia secundario al Virus Zika, se agrupan bajo el síndrome congénito del Zika (SZC), el extremo más grave de un espectro de defectos de nacimiento que incluyen además alteraciones en las funciones sensoriales de visión y audición, ya que el virus Zika está incluido dentro de las infecciones virales causadoras de hasta el 40% de las pérdidas auditivas congénitas y adquiridas. Objetivo: identificar en la literatura científica la relación existente entre el Síndrome Congénito del Zika y la pérdida de audición en infantes. Metodología: Revisión sistemática en las principales bases de datos como Science Direct ­ Elsevier, Online Library, Coronavirus Databases, Embase, Springer, entre otras. Resultados: Se encontraron 18 artículos indexados con descriptores de los cuales se incluyeron 8 al cumplir con los criterios de inclusión y exclusión. Discusiones: se evidencia que la pérdida de audición está presente en las diversas poblaciones de infantes evaluadas por medio de pruebas objetivas, las cuales permiten obtener respuestas importantes de la actividad eléctrica a nivel del nervio y la vía auditiva, presentándose fallas notables en los niños con síndrome congénito del Zika. Conclusiones: De acuerdo a los estudios incluidos en la presente investigación es poca la evidencia científica que pueda aportar una asociación significativa y absoluta entre el síndrome congénito del Zika y la pérdida de audición en infantes.

Introduction: Infants with microcephaly secondary to Zika Virus, are grouped under Congenital Zika Syndrome (CZS), the most severe end of a spectrum of birth defects that also include alterations in the sensory functions of vision and hearing, since Zika virus is included within the viral infections causing up to 40% of congenital and acquired hearing loss. Objective: to identify in the scientific literature the relationship between congenital Zika syndrome and hearing loss in infants. Methodology: Systematic review in the main databases such as Science Direct ­ Elsevier, Online Library, Coronavirus Databases, Embase, Springer, among others. Results: 18 articles were found indexed with descriptors of which 8 were included as they met the inclusion and exclusion criteria. Discussions: it is evident that hearing loss is present in the various populations of infants evaluated by means of objective tests, which allow obtaining important responses of the electrical activity at the level of the auditory nerve and pathway, presenting notable failures in children with congenital Zika syndrome. Conclusions: According to the studies included in the present investigation there is little scientific evidence that can provide a significant and absolute association between congenital Zika syndrome and hearing loss in infants.

Relationship between microcephaly and indicators of social inequality in the state of Paraíba, Brazil

ABSTRACT Objective To analyze the relationship between microcephaly and social inequality indicators in the state of Paraíba during the biennium January 2015 and December 2016. Methods Ecological study with data from newborn microcephaly records and municipal socioeconomic, environmental, and demographic indicators was conducted using two health information systems from the Brazilian Ministry of Health (SINASC and SINAN) and the Brazilian Institute of Geography and Statistics. A Poisson multiple regression model was applied with a significance level of 5%. Results Among 223 municipalities in Paraíba, 74 registered new cases of microcephaly. The number of Zika virus cases, number of inhabitants, number of households without adequate water supply, and household income were predictor variables of the number of new cases of microcephaly in Paraíba. Conclusion Microcephaly is associated with indicators of social inequality in Paraíba. Zika virus cases, water supply, and family income are the indicators that best explain the increase in microcephaly cases. Therefore, these variables must be monitored by health professionals and authorities.

Speech-language-hearing therapists' perception of orofacial myofunctional changes in subjects with congenital Zika syndrome / Percepção dos fonoaudiólogos sobre alterações miofuncionais orofaciais em sujeitos com Síndrome Congênita pelo Zika Vírus

ABSTRACT Purpose: to investigate the profile of speech-language-hearing therapists from Northeastern Brazil assisting children presented with congenital Zika syndrome and their perception of these children's orofacial myofunctional aspects and speech-language-hearing intervention procedures. Methods: a cross-sectional observational study with quantitative/qualitative analysis. The data collection instrument was an online questionnaire with 34 items on the speech-language-hearing therapists' sociodemographic information and perception of the study topic. The sample comprised 23 speech-language-hearing therapists from the nine Northeastern states. Results: altogether, 96% of the sample were females. Most professionals had more than 3 years of experience with congenital Zika syndrome. Concerning stomatognathic system characterization, the professionals described a greater degree of change in aspects of orofacial muscle posture and mobility. Regarding oral functions, they perceived greater changes in speech and swallowing liquids and solid foods. There was a greater degree of change in masticating solids than in swallowing liquids. Conclusion: most speech-language-hearing therapists in the research had a specialization degree, especially in dysphagia and oral-motor control. Most of them had more than 3 years of experience following up with children with congenital Zika syndrome, which indicates a satisfactory time working with this population to help identify orofacial myofunctional changes in them. The professionals stated that orofacial muscle posture and mobility, speech, and swallowing liquids and solid foods were the most changed aspects.

Health-related quality of life in children with cerebral palsy associated with congenital Zika infection / Qualidade de vida relacionada à saúde em crianças com paralisia cerebral associada a síndrome da Zika congênita

Abstract Objective: To describe the health-related quality of life (QOL) in children with cerebral palsy (CP) associated with congenital Zika infection. Methods: Cross-sectional study of a consecutive series of children, followed in a referral multicentric rehabilitation network in Brazil. We invited the caregivers to respond to the Brazilian version of the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM) questionnaire. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) 26.0™. We used absolute and relative frequencies for categorical variables and mean and standard deviation for continuous variables. Results: The sample consisted of 193 children, at mean age of 50.3±7.6 months. We observed a predominance of children with cerebral palsy (CP) with Gross Motor Function Classification System (GMFCS) level V (93.7%). Epilepsy (88.4%) was the most common comorbidity. CPCHILDTM mean scores were activities of daily living (ADL)/personal care 43.2±12.6; positioning, transferring and mobility 33.7±16.5; comfort and emotions 84.4±15.2; communication and social interaction (CoSI) 48.2±24.3; health 70.9±17.1; and overall quality of life (OQOL) 72.1±17.1. Total score was 54.8±11.3. Conclusions: Among children with cerebral palsy (CP) related to congenital Zika syndrome, the quality of life (QOL) scores were very similar to other populations with cerebral palsy (CP). The activities of positioning, transferring and mobility had the greatest impact on health-related quality of life (QOL). Rehabilitation strategies and public policies should prioritize aspects related to mobility for this population.

Conclusões: Entre as crianças com paralisia cerebral relacionada à síndrome do zika congênita, as atividades de posicionamento, transferência e mobilidade tiveram maior impacto na qualidade de vida relacionada à saúde, semelhantemente a outras etiologias de paralisia cerebral. As estratégias de reabilitação e as políticas públicas devem priorizar os aspectos relacionados à mobilidade dessa população.

Alterations in deglutition in children with congenital Zika virus syndrome / Alterações na deglutição em crianças com síndrome congênita do vírus Zika

ABSTRACT Purpose To characterize swallowing in children with congenital Zika virus syndrome in comparison to typical children. Methods This cross-sectional study enrolled 45 children diagnosed with congenital Zika virus syndrome and 45 others with typical development. Swallowing was evaluated through clinical feeding evaluations Protocolo de Avaliação Clínica da Disfagia Pediátrica and using acoustic swallowing parameters (Doppler sonar). Results The mean age of children with congenital Zika virus syndrome was 26.69 ± 4.46 months and the mean head circumference was 29.20 ± 1.98 cm. Moderate/severe oropharyngeal dysphagia was found in 32(71.1%) of the children with congenital Zika virus syndrome. Significant differences were found between the groups on clinical evaluation: Children with congenital Zika virus syndrome presented insufficient lip closure 42(93.3%) and altered tonus of the tongue 35(77.8%) and cheeks 34(75.6%). In the children in the comparison group, only 6(13.3%) presented insufficient lip closure and 1(2.2%) had inadequate tongue posture. Changes during swallowing with liquid and spoonable food were not observed in the comparison group. When liquid/food was offered, affected children presented difficulties in sipping movements 14(77.8%) and lip/spoon contact 35(75%). The presence of residual food in the oral cavity after swallowing 38(86.4%) and clinical signs indicative of laryngotracheal penetration/aspiration, such as coughing, gagging and/or labored breathing, were also notable. No differences were found between the groups with regard to the acoustic parameters evaluated instrumentally. Conclusion Children with congenital Zika virus syndrome present alterations in the oral phase of swallowing, as well as clinical signs indicative of pharyngeal phase impairment.
