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.

RESUMO Objetivo: Descrever a qualidade de vida relacionada à saúde em crianças com paralisia cerebral associada à infecção congênita pelo zika. Métodos: Estudo transversal de série consecutiva de casos de crianças acompanhadas em uma rede multicêntrica de reabilitação no Brasil. Convidamos o(s) cuidador(es) a responder à versão brasileira do Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM). A análise estatística foi realizada com o pacote estatístico Statistical Package for the Social Sciences (SPSS) 26.0™. Para variáveis categóricas, foram utilizadas frequências absolutas e relativas e, para variáveis contínuas, média e desvio padrão. Resultados: Cento e noventa e três crianças, com idade média de 50,3±7,6 meses, foram incluídas. Observou-se predomínio de crianças com paralisia cerebral Gross Motor Function Classification System (GMFCS) nível V (93,7%). Epilepsia (88,4%) foi a comorbidade mais comum. As pontuações médias do CPCHILDTM foram: atividades de vida diária/cuidados pessoais 43,2±12,6; posicionamento, transferência e mobilidade 33,7±16,5; conforto e emoções 84,4±15,2; comunicação e interação social 48,2±24,3; saúde 70,9±17,1; e qualidade de vida geral 72,1±17,1. A pontuação total foi 54,8±11,3. 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.

BACKGROUND Serological evidence of West Nile virus (WNV) infection has been reported in different regions of Brazil from equine and human hosts but the virus had never been isolated in the country. OBJECTIVES We sought to identify the viral etiology of equine encephalitis in Espírito Santo state. METHODS We performed viral culture in C6/36 cells, molecular detection of WNV genome, histopathology and immunohistochemistry from horse cerebral tissue. We also carried out sequencing, phylogenetic analysis and molecular clock. FINDINGS Histopathologic analysis from horse cerebral tissue showed injury related to encephalitis and WNV infection was confirmed by immunohistochemistry. The virus was detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR) from brain tissue and subsequently isolated in C6/36 cells. WNV full-length genome was sequenced showing the isolated strain belongs to lineage 1a. The molecular clock indicated that Brazilian WNV strain share the same common ancestor that were circulating in US during 2002-2005. MAIN CONCLUSIONS Here we report the first isolation of WNV in Brazil from a horse with neurologic disease, which was clustered into lineage 1a with others US WNV strains isolated in beginning of 2000’s decade.

Abstract We report a case of encephalitis associated with Zika virus infection and reactivation of varicella-zoster virus in the central nervous system of a Brazilian child. This case raises the possibility that reactivation of the latent varicella-zoster virus may be a mechanism of neurological impairment induced by acquired Zika virus infection.

Abstract: En | Text: En | PDF: En

This study showed that laboratory markers of recent infection by dengue, Zika or chikungunya arboviruses were detected in the biological samples of approximately one-third of patients with encephalitis, myelitis, encephalomyelitis or Guillain-Barré syndrome, in a surveillance programme in Piauí state, Brazil, between 2015-2016. Fever and myalgia had been associated with these cases. Since in non-tropical countries most infections or parainfectious diseases associated with the nervous system are attributed to herpesviruses, enteroviruses, and Campylobacter jejuni, the present findings indicate that in tropical countries, arboviruses may now play a more important role and reinforce the need for their surveillance and systematic investigation in the tropics.

OBJECTIVE: to analyze drug prescriptions in three inpatient units of a university hospital in the State of Sergipe. METHOD: this was a descriptive, transversal, and documental study. Data were collected in inpatient units during ten days in March of 2012. The sample consisted of 286 prescriptions with 2,605 items related to drugs. The study was approved by the Ethics and Research Committee of the Federal University of Sergipe, under number CAAE 0263.0.107.000-11. RESULTS: out of the total prescriptions analyzed, 48% were typed, 98% did not show the patients record number, and 100.0% contained abbreviations and acronyms. Out of the 4,522 prescribed drugs, a prevalence in the absence of dosage form, drug name, and other data on the medication was observed. CONCLUSION: the existence of inadequacies in the records of drug prescriptions has shown that the administration of drugs in the studied institution can pose risks to patient safety, indicating the need for the implementation of corrective actions.

Abstract: En | Text: En | PDF: En

IntroductionThe yellow fever epidemic that occurred in 1972/73 in Central Brazil surprised the majority of the population unprotected. A clinical-epidemiological survey conducted at that time in the rural area of 19 municipalities found that the highest (13.8%) number of disease cases were present in the municipality of Luziânia, State of Goiás.MethodsThirty-eight years later, a new seroepidemiological survey was conducted with the aim of assessing the degree of immune protection of the rural population of Luziânia, following the continuous attempts of public health services to obtain vaccination coverage in the region. A total of 383 volunteers, aged between 5 and 89 years and with predominant rural labor activities (75.5%), were interviewed. The presence of antibodies against the yellow fever was also investigated in these individuals, by using plaque reduction neutralization test, and correlated to information regarding residency, occupation, epidemiological data and immunity against the yellow fever virus.ResultsWe found a high (97.6%) frequency of protective titers (>1:10) of neutralizing antibodies against the yellow fever virus; the frequency of titers of 1:640 or higher was 23.2%, indicating wide immune protection against the disease in the study population. The presence of protective immunity was correlated to increasing age.ConclusionsThis study reinforces the importance of surveys to address the immune state of a population at risk for yellow fever infection and to the surveillance of actions to control the disease in endemic areas.

Abstract: En | Text: En | PDF: En

Because an enriched environment (EE) enhances T-cell activity and T-lymphocytes contribute to immunopathogenesis during heterologous dengue virus (DENV) infections, we hypothesised that an EE increases dengue severity. To compare single serotype (SS) and antibody-enhanced disease (AED) infections regimens, serial intraperitoneal were performed with DENV3 (genotype III) infected brain homogenate or anti-DENV2 hyperimmune serum followed 24 h later by DENV3 (genotype III) infected brain homogenate. Compared AED for which significant differences were detected between the EE and impoverished environmental (IE) groups (Kaplan-Meyer log-rank test, p = 0.0025), no significant differences were detected between the SS experimental groups (Kaplan-Meyer log-rank test, p = 0.089). Survival curves from EE and IE animals infected with the AED regimen were extended after corticoid injection and this effect was greater in the EE than in the IE group (Kaplan-Meyer log-rank test, p = 0.0162). Under the AED regimen the EE group showed more intense clinical signs than the IE group. Dyspnoea, tremor, hunched posture, ruffled fur, immobility, pre-terminal paralysis, shock and death were associated with dominant T-lymphocytic hyperplasia and presence of viral antigens in the liver and lungs. We propose that the increased expansion of these memory T-cells and serotype cross-reactive antibodies facilitates the infection of these cells by DENV and that these events correlate with disease severity in an EE.

Abstract: En | Text: En | PDF: En

Dengue fever is the most important arbovirus infection found in tropical regions around the world. Dispersal of the vector and an increase in migratory flow between countries have led to large epidemics and severe clinical outcomes, such as dengue haemorrhagic fever and dengue shock syndrome. This study analysed the genetic variability of the dengue virus serotype 1 (DENV-1) in Brazil with regard to the full-length structural genes C/prM/M/E among 34 strains isolated during epidemics that occurred in the country between 1994-2011. Virus phylogeny and time of divergence were also evaluated with only the E gene of the strains isolated from 1994-2008. An analysis of amino acid differences between these strains and the French Guiana strain (FGA/89) revealed the presence of important nonsynonymous substitutions in the amino acid sequences, including residues E297 (Met→Thr) and E338 (Ser→Leu). A phylogenetic analysis of E proteins comparing the studied isolates and other strains selected from the GenBank database showed that the Brazilian DENV-1 strains since 1982 belonged to genotype V. This analysis also showed that different introductions of strains from the 1990s represented lineage replacement, with the identification of three lineages that cluster all isolates from the Americas. An analysis of the divergence time of DENV-1 indicated that the lineage circulating in Brazil emerged from an ancestral lineage that originated approximately 44.35 years ago.

Abstract: En | Text: En | PDF: En

Rocio virus (ROCV) is an encephalitic flavivirus endemic to Brazil. Experimental flavivirus infections have previously demonstrated a persistent infection and, in this study, we investigated the persistence of ROCV infection in golden hamsters (Mesocricetus auratus). The hamsters were infected intraperitoneally with 9.8 LD50/0.02 mL of ROCV and later anaesthetised and sacrificed at various time points over a 120-day period to collect of blood, urine and organ samples. The viral titres were quantified by real-time-polymerase chain reaction (qRT-PCR). The specimens were used to infect Vero cells and ROCV antigens in the cells were detected by immunefluorescence assay. The levels of antibodies were determined by the haemagglutination inhibition technique. A histopathological examination was performed on the tissues by staining with haematoxylin-eosin and detecting viral antigens by immunohistochemistry (IHC). ROCV induced a strong immune response and was pathogenic in hamsters through neuroinvasion. ROCV was recovered from Vero cells exposed to samples from the viscera, brain, blood, serum and urine and was detected by qRT-PCR in the brain, liver and blood for three months after infection. ROCV induced histopathological changes and the expression of viral antigens, which were detected by IHC in the liver, kidney, lung and brain up to four months after infection. These findings show that ROCV is pathogenic to golden hamsters and has the capacity to cause persistent infection in animals after intraperitoneal infection.

A etapa de aclimatização é uma fase crítica da micropropagação vegetal, podendo ser responsável por altos índices de mortalidade, baixas taxas de crescimento e desuniformidade das plantas. Um fator fundamental na aclimatização é tipo de substrato a ser utilizado. Nesse trabalho, objetivou-se avaliar o efeito de diferentes substratos na aclimatização de mudas micropropagadas de helicônia (Heliconia lingulata Ruiz & Pav.). A pesquisa foi conduzida em um túnel alto de cultivo forçado pertencente à Embrapa Agroindústria Tropica,l situada no município de Fortaleza - CE, Brasil (3º44'S e 38º33'W). O delineamento experimental utilizado foi em blocos casualizados com cinco tratamentos e cinco repetições. Os substratos testados foram: T1 -pó-de-coco seco + húmus de minhoca + solo (PCS+H+S); T2 -pó-de-coco verde + vermiculita + composto de cama de frango (PCV+V+CCF); T3 -pó-de-coco verde + húmus de minhoca + solo (PCV+H+S); T4 -pó-de-coco seco + vermiculita + composto de cama de frango (PCS+V+CCF); e T5 - substrato comercial Hortimix® (HORT). As variáveis agronômicas, avaliadas no experimento foram: altura da planta, número de folhas e diâmetro do pseudocaule. Os resultados do experimento evidenciaram o maior desenvolvimento das mudas micropropagadas de helicônia, quando o substrato utilizado foi a combinação pó de coco verde + húmus de minhoca + solo (PCV + H + S).

Acclimatization is the most important and critical plant micropropagation phase. It can be responsible for high mortality rate, low growth rate, and plant heterogeneity. One of the limiting factors in plant acclimatization is the substrate. The objective of this work was to evaluate the effect of different substrates on the acclimatization of micropropagated heliconia plants (Heliconia lingulata Ruiz & Pav.). The research was carried out in a greenhouse at the Embrapa Tropical Agroindustry located in Fortaleza, Ceará, Brazil (3º44' S and 38º33' W). The experimental design was a randomized block with five treatments and five repetitions. The substrates tested were: T1 - dry 'coir' dust + earthworm humus + soil (DCD+EH+S); T2 - green 'coir' dust + vermiculite + poultry litter (GCD+V+PL); T3 - green 'coir' dust + earthworm humus + soil (GCD+EH+S); T4 - dry 'coir' dust + vermiculite + poultry litter (DCD+V+PL) and T5 -Hortimix® (HORT). The variables evaluated in the experiments were plant height, number of leaves, and diameter of the pseudostem. The results revealed that the best development of micropropagated heliconia plants was with a combination of green 'coir' dust + earthworm humus + soil (GCD+EH+S).

O presente estudo descreve os aspectos eco-epidemiológicos sobre arbovírus nos Municípios de Novo Progresso e Trairão, Estado do Pará, Brasil, na área de influência da BR 163. Anticorpos IH foram detectados para diferentes arbovírus, com reações monotípicas para os VMAY e VORO, dois importantes arbovírus associados a epidemias na Amazônia. Anticorpos IgM para o VORO e VMAY foram detectados em soros humanos, sugerindo infecção recente por esses arbovírus. Duas cepas do VDEN-3 foram isoladas de pacientes febris residentes em Novo Progresso e identificadas como genótipo III. Em termos gerais, os dados obtidos sugerem uma área propícia para a circulação e manutenção de arbovírus e uma população pouco imunizada. Portanto, é importante um monitoramento dinâmico das populações locais e de imigrantes e de animais silvestres quanto à presença de anticorpos e isolamentos de arbovírus, o que permitirá um efetivo controle das infecções por esses agentes virais em residentes da área da rodovia dentro do território paraense.

The current study describes the eco-epidemiological aspects of arbovirus diseases in the municipalities (counties) of Novo Progresso and Trairão, Para State, Brazil, in the area affected by highway BR-163. Hemagglutination inhibition (HI) antibodies to different arboviruses were detected, with monotypic reactions to MAYV and OROV, two important arboviruses associated with epidemics in the Amazon. IgM antibodies to OROV and MAYV were found in human sera, suggesting recent infections by these viruses. Two DENV-3 strains were isolated from febrile patients in Novo Progresso and identified as genotype III strains. In general, the data suggest that the area displays ideal conditions for maintenance and circulation of arboviruses, plus a population with low immunization levels. Dynamic surveillance of local immigrants and wild animals is thus important, focusing on antibody prevalence and isolation of arboviruses, thereby allowing effective control of infections by these viral agents in the resident population along highway BR-163 in Pará State.
