ABSTRACT Purpose To validate the appearance and content of the DHACA method to develop communication skills in autism. Methods This qualitative and quantitative validation study included 10 speech-language-hearing judges with expertise in alternative communication. The judges received the communication book, the description of the principles, skills, and strategies in the DHACA method, and a form with items for them to appraise the appearance and content of the method. The validity was calculated with the content validity index. Results The response analysis made it possible to calculate the degree of agreement between judges and develop the new instrument version. The calculation of the content validity index revealed excellent content validity. The judges made suggestions regarding the content of the communication book, texts regarding the participation of communication partners and modeling, using cues, and communicative skills. Conclusion The degree of agreement between judges ensured the validation of the appearance and content of the DHACA method, considering the items alone and the whole instrument. Hence, its use can be recommended for speech-language-hearing clinical practice.

ABSTRACT This paper aimed to investigate the contribution of speech-language-hearing teletherapy to the development of communication skills in children with autism spectrum disorders during the coronavirus-19 pandemic. This qualitative, interventive, longitudinal case series study analyzed data from the medical records of patients, based on instructions given to their families via speech-language-hearing teletherapy during social isolation. It was part of a public outreach program conducted in a speech-language-hearing teaching clinic, aiming to analyze results in the field of language. All children progressed in various aspects, such as the development of communication skills, expanded vocabulary, increased naming and asking, morphosyntactic development, and advancements in the use of augmentative and alternative communication. Also, shared attention and eye contact increased, the interaction with the family improved, and inadequate behaviors decreased; there was greater autonomy in daily routine and greater attention during activities; increased interest in toys during play and longer and more frequent playing, associated with decreased screen time. In conclusion, the results demonstrated progress in communication and social interaction after the speech-language-hearing teletherapy for children presented with autism spectrum disorders during the coronavirus-19 pandemic.

RESUMO Esse trabalho teve por objetivo investigar a contribuição da Telefonoaudiologia no desenvolvimento das habilidades comunicacionais de crianças com Transtorno do Espectro do Autismo durante a pandemia da Coronavírus-19. Trata-se de um estudo interventivo, longitudinal de abordagem qualitativa, do tipo série de casos, realizado por meio da análise de dados dos prontuários de pacientes atendidos, a partir das orientações às famílias, via telefonoaudiologia, passadas durante o período de isolamento social, em um projeto de extensão, realizado em uma clínica-escola de Fonoaudiologia, buscando analisar os resultados obtidos na área da linguagem. Foi observada evolução em todas as crianças, em diversos aspectos, como desenvolvimento das habilidades comunicativas com ampliação do vocabulário, aumento de nomeações e solicitações, desenvolvimento morfossintático e avanços no uso da Comunicação Aumentativa e Alternativa. Além do aumento na atenção compartilhada e no contato visual, houve melhora na interação com os familiares e redução dos comportamentos inadequados; maior autonomia na rotina diária e maior atenção durante as atividades; aumento do interesse pelos brinquedos durante a brincadeira e ampliação da frequência e do tempo do brincar, associado à diminuição do uso de telas. Concluiu-se que os resultados demonstraram avanços na comunicação e na interação social, após o teleconsulta fonoaudiológico para crianças com Transtorno do Espectro do Autismo durante a pandemia da Coronavírus-19.

ABSTRACT Alternative communication has been successfully used in interventions to develop communication skills in children with ASD. However, few studies in Brazil have approached nonverbal adolescents with autism. This article aimed to demonstrate the impact of using an alternative communication system on the development of communication skills in a nonverbal adolescent presented with ASD. This is a single-case study with longitudinal intervention. Skills were assessed with the Communication Assessment in Autism Spectrum Disorder (ACOTEA). There was progress in communicative and behavioral skills. Receptive communications had a greater variation between the first, second, and third applications, increasing from 50% to 66.60% and then 83.30%, followed by social behavior, which increased from 45.80% to 70.80% and then 75%. The use of alternative communication with a robust communication system indicated evidence of the development of communication skills and social behavior in the adolescent with ASD that received the treatment.

RESUMO O uso da Comunicação Alternativa para o desenvolvimento de habilidades comunicacionais de crianças com TEA tem sido aplicado com êxito nas intervenções. Entretanto, no Brasil, são escassos os estudos na faixa etária da adolescência e autistas não verbais. Este artigo tem como objetivo demonstrar o impacto do uso de um sistema de comunicação alternativa no desenvolvimento das habilidades comunicacionais em um adolescente não-verbal com TEA. Trata-se de estudo de intervenção longitudinal do tipo estudo de caso único. As habilidades foram avaliadas pelo protocolo de Avaliação da Comunicação no Transtorno do Espectro do Autismo - ACOTEA. Constatou-se que houve avanço nas habilidades comunicativas e comportamentais. A comunicação receptiva apresentou maior variação entre a primeira, segunda e terceira aplicação, evoluindo de 50% para 66,60% e, no final, para 83,30%, seguida do comportamento social 45,80% para 70,80% e depois para 75%. O uso da Comunicação Alternativa com um sistema robusto de comunicação apontou evidências do desenvolvimento de habilidades comunicativas bem como no comportamento social no adolescente com TEA assistido.

Abstract Purpose: To evaluate the effects of splenic ischemic preconditioning (sIPC) on oxidative stress induced by hepatic ischemia-reperfusion in rats. Methods: Fifteen male Wistar rats were equally divided into 3 groups: SHAM, IRI and sIPC. Animals from IRI group were subjected to 45 minutes of partial liver ischemia (70%). In the sIPC group, splenic artery was clamped in 2 cycles of 5 min of ischemia and 5 min of reperfusion (20 min total) prior to hepatic ischemia. SHAM group underwent the same surgical procedures as in the remaining groups, but no liver ischemia or sIPC were induced. After 1h, hepatic and splenic tissue samples were harvested for TBARS, CAT, GPx and GSH-Rd measurement. Results: sIPC treatment significantly decreased both hepatic and splenic levels of TBARS when compared to IRI group (p<0.01). Furthermore, the hepatic and splenic activities of CAT, GPx and GSH- Rd were significantly higher in sIPC group than in IRI group. Conclusion: sIPC was able to attenuate hepatic and splenic IRI-induced oxidative stress.

BACKGROUND There is little information on the effect of using deltamethrin-impregnated dog collars for the control of canine visceral leishmaniasis. OBJECTIVES The objective of this study was to evaluate the effectiveness of the use of 4% deltamethrin-impregnated collars (Scalibor®) in controlling visceral leishmaniasis in Lutzomyia longipalpis by comparing populations in intervention and non-intervention areas. METHODS Phlebotomine flies were captured over 30 months in four neighbourhoods with intense visceral leishmaniasis transmission in Fortaleza and Montes Claros. We calculated the rates of domicile infestation, relative abundance of Lu. longipalpis, and Lu. longipalpis distribution in each site, capture location (intra- and peridomestic locations) and area (intervention and non-intervention areas). FINDINGS In the control area in Fortaleza, the relative abundance of Lu. longipalpis was 415 specimens at each capture site, whereas in the intervention area it was 159.25; in Montes Claros, the relative abundance was 5,660 specimens per capture site in the control area, whereas in the intervention area it was 2,499.4. The use of dog collars was associated with a reduction in captured insects of 15% (p = 0.004) and 60% (p < 0.001) in Montes Claros and Fortaleza, respectively. MAIN CONCLUSIONS We observed a lower vector abundance in the intervention areas, suggesting an effect of the insecticide-impregnated collars.

ABSTRACT OBJECTIVE: To test several weaning predictors as determinants of successful extubation after elective cardiac surgery. METHODS: The study was conducted at a tertiary hospital with 100 adult patients undergoing elective cardiac surgery from September to December 2014. We recorded demographic, clinical and surgical data, plus the following predictive indexes: static compliance (Cstat), tidal volume (Vt), respiratory rate (f), f/ Vt ratio, arterial partial oxygen pressure to fraction of inspired oxygen ratio (PaO2/FiO2), and the integrative weaning index (IWI). Extubation was considered successful when there was no need for reintubation within 48 hours. Sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+), and negative likelihood ratio (LR-) were used to evaluate each index. RESULTS: The majority of the patients were male (60%), with mean age of 55.4±14.9 years and low risk of death (62%), according to InsCor. All of the patients were successfully extubated. Tobin Index presented the highest SE (0.99) and LR+ (0.99), followed by IWI (SE=0.98; LR+ =0.98). Other scores, such as SP, NPV and LR-were nullified due to lack of extubation failure. CONCLUSION: All of the weaning predictors tested in this sample of patients submitted to elective cardiac surgery showed high sensitivity, highlighting f/Vt and IWI.

O principal vetor de leishmaniose visceral (LV) no Brasil é Lutzomyia longipalpis. Entretanto, a ausência de L. longipalpis em área com casos autóctones de LV demonstra a existência de outras espécies na transmissão dessa doença. Estudo realizado na cidade de La Banda, Argentina, e São Vicente Férrer, Brasil, correlacionou a ausência de L. longipalpis e a presença de Lutzomyia migoneicom casos autóctones de LV. Em São Vicente Férrer, foi comprovada a infecção natural de L. migonei por Leishmania infantum chagasi. Dessa forma, o objetivo deste trabalho foi avaliar a ecologia dos flebotomíneos L. longipalpis e L. migonei no município de Fortaleza, área endêmica para LV. A captura de flebotomíneos foi realizada em 22 pontos de coleta distribuídos nas quatro regiões do município de Fortaleza. No total, foram capturados 32.403 flebotomíneos. Destes, 18.166 (56%) eram da espécie L. longipalpis e 14.237 (44%) eram L. migonei. Houve diferença significativa de densidade entre os vetores em cada local de captura (intra e peri) (p<0,0001). Esses achados confirmam que, na cidade de Fortaleza, L. migonei e L. longipalpis estão bem distribuídos, bem como adaptados ao ambiente intradomiciliar e que L. migonei, possivelmente, compartilhe com L. longipalpis o papel de vetor da LV em Fortaleza.

The main vector for visceral leishmaniasis (VL) in Brazil is Lutzomyia longipalpis. However, the absence of L. longipalpis in a region of autochthonous VL demonstrates the participation of other species in the transmission of the parasite. Studies conducted in La Banda, Argentina, and São Vicente Férrer, Pernambuco State, Brazil, have correlated the absence of L. longipalpisand the presence of L. migonei with autochthonous cases of VL. In São Vicente Férrer, Pernambuco, there was evidence for the natural infection of L. migonei with Leishmania infantum chagasi. Thus, the objective of this work was to assess the ecology of the sand flies L. longipalpis and L. migonei in Fortaleza, an endemic area for VL. Insect capture was conducted at 22 sampling points distributed across four regions of Fortaleza. In total, 32,403 sand flies were captured; of these, 18,166 (56%) were identified as L. longipalpis and 14,237 (44%) as L. migonei. There were significant density differences found between the vectors at each sampling site (indoors and outdoors) (p <0.0001). These findings confirm that L. migonei and L. longipalpis are distributed throughout Fortaleza, where they have adapted to an indoor environment, and suggest that L. migonei may share the role as a vector with L. longipalpis in the transmission of VL in Fortaleza.

O objetivo foi realizar um estudo epidemiológico para determinar as áreas de risco de transmissão de leishmaniose visceral pela detecção e quantificação de infecções naturais por Leishmania infantum em Lutzomyia longipalpis. As coletas foram realizadas entre fevereiro de 2009 e janeiro de 2010 em 21 locais, distribuídos em quatro regiões do município de Fortaleza. As amostras foram testadas quanto à presença de DNA de Leishmania por PCR em tempo real (qPCR). Dos 123 pools de flebotomíneos investigados, 45 foram positivos para L. infantum, e a taxa de infecção mínima foi de 3,7%. Nas regiões Norte, Sul, Leste e Oeste, a prevalência de flebotomíneos infectados foi de 3,4%, 4,7%, 4,9% e 8,4%, respectivamente. A carga de parasitas nos pools variou de 2,45 ± 0,96 a 2.820.246 ± 106.072. Não foram observadas diferenças significativas na frequência de flebotomíneos infectados entre as regiões (P = 0,3014), estação do ano (P = 0,3906) ou localização da armadilha (P = 0,8486). Foram observadas diferenças significativas na frequência de flebotomíneos somente na região oeste durante a estação chuvosa (P = 0,0152). A qPCR foi capaz de detectar e quantificar L. infantum em L. longipalpis, identificando as áreas de maior risco de transmissão de leishmaniose visceral.

The objective of this study was to perform an epidemiological survey to determine the areas at risk of visceral leishmaniasis through the detection and quantification of natural infection by Leishmania infantumin Lutzomyia longipalpis. The sandflies were captured between February 2009 and January 2010, at 21 sites in four regions of the Fortaleza municipality. Samples were screened for the presence of Leishmania DNA by Real Time PCR (qPCR), amplification of kDNA minicircle sequence. Out of the 123 pools of analyzed sandflies, 45 were positive for L.infantum, and the minimum infection rate was 3.7%. In the north, south, east and west regions, the pool screen assay predicted sand-fly infection prevalence of 3.4%, 4.7%, 4.9% and 8.4%, respectively. The parasite load ranged from 2.45 ± 0.96 to 2,820,246 ± 106,072. No statistical differences were found with respect to the frequency of sand-fly infection between the regions (P=0.3014), seasons (P = 0.3906) or trap locations (P = 0.8486). Statistical differences were found with respect to the frequency of sand-fly infection between the two seasons only in the west region (P=0.0152). The qPCR was able to detect and quantify L. infantum in L. longipalpis, therefore succeeding in identifying the areas of greatest risk of VL transmission.
