Abstract Objective To evaluate otolith function by comparing the findings of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential and the ocular Vestibular Evoked Myogenic Potential tests in patients in the inter-crisis period of unilateral definite Meniere's disease. Methods The sample consisted of an experimental group (n = 22; 10 men and 12 women, mean age 47.32 ± 12.82 years) with definite unilateral Meniere's disease and a control group (n = 14; 5 men and 9 women, with a mean age of 41.64 ± 13.45 years). They all underwent vestibular evaluation by means of Subjective Visual Vertical with the bucket method and, cervical and ocular Vestibular Evoked Myogenic Potential tests. The data were collected and subjected to statistical analysis. Results The results of the comparison of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential, the ocular Vestibular Evoked Myogenic Potential and, the association of cervical Vestibular Evoked Myogenic Potential with the ocular Vestibular Evoked Myogenic Potential showed no significant difference, indicating concordance among the tests. Conclusion The identified abnormalities and the concordance between the combined proportion of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential and the ocular Vestibular Evoked Myogenic Potential findings indicate that the association of these three tests contributes to the identification of sustained and transient otolith dysfunction in the inter-crisis of unilateral definite Meniere’s disease. Level of evidence 2.

ABSTRACT. An experiment was conducted to evaluate the effect of diets with reduced energy level content, supplemented with carbohydrase, on broiler performance and the coefficient of metabolizability of nutrients. A total of 720 one-day-old male Cobb-500 chicks were distributed in a completely randomized design, with six treatments, eight repetitions of 15 birds each. The treatments were: (1) a positive control, basal diet to meet the requirements of broiler chickens (PC); (2) a negative control, basal diet with a reduction of 80 kcal kg-1 (NC); (3) NC + alphagalactosydase; (4) NC + xylanase; (5) NC + xylanase and alphagalactosydase, and (6) NC + enzymatic blend (alphagalactosydase, xylanase, pectinase and amylase). The nutrient digestibility was not improved by use of enzymes. At 7 days of age, the broilers which were fed diets supplemented with enzymes showed a lower feed intake (FI) and better feed conversion ratio (FCR) than the broilers fed on PC. Both the NC and enzymatic blend resulted in a worse performance of the broilers at 21, 35 and 42 days old. The use of alphagalactosydase and xylanase, isolated or in combination, in a corn-soybean meal-based diet is effective in improving the growth performance of broilers fed energy-reduced diets.

Abstract This study evaluated the impact of processing, packages (amber and transparent glass jars), and storage time on the stability of the bioactive compounds (total phenolic compounds and vitamin C), and antioxidant activity of mangaba jelly. Jelly processing, significantly (p < 0.05) decreased the bioactive compounds and antioxidant activity. The storage time, significantly (p < 0.05) influenced all the variables studied in this work, although they were not affected by packages. A significant decrease of the bioactive compounds and antioxidant activity was observed during the jelly storage. HPLC-DAD/UV-Vis analyses allowed to identify 10 phenolic compounds, including flavonoids and non-flavonoids, and among these, quercetin and catechin were the major compounds. After processing, all these compounds decreased significantly (p < 0.05), except for the gallic acid and the p-coumaric acid, which presented an increasing tendency. During jelly storage, only gallic acid, caffeic acid, catechin, and rutin were affected. Despite the reduction in the antioxidant activity and bioactive compounds studied, mangaba jelly retained good levels of them and may be considered a potential novel functional food.

ABSTRACT This study aims to assess COVID-19 and other respiratory viruses in pediatric patients. Between April 17 and September 30, 2020, we collected 1,566 respiratory samples from 1,044 symptomatic patients who were younger than 18 years old to assess SARS-CoV-2 infection. Of these, 919 were analyzed for other respiratory pathogens (ORP). Patients with laboratory-confirmed COVID-19 or ORP were included. We evaluated 76 pediatric COVID-19 infections and 157 other respiratory virus infections. Rhinovirus occurred in 132/157 (84%). COVID-19 patients who were significantly older, had more fevers, headaches and pneumonia than those with ORP. The median white blood cell count was lower in patients with SARS-CoV-2 than in those with ORP (6,470 versus 8,170; p=0.02). COVID-19 patients had significantly worse symptoms than those with ORP.

RESUMO O DC de Neuroimunologia da ABN e o BCTRIMS trazem, nesse documento, as recomendações sobre vacinação da população com doenças desmielinizantes do sistema nervoso central (SNC) contra infecções em geral e contra o coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2), causador da COVID-19. Destaca-se a gravidade do atual momento frente ao avanço da COVID-19 em nosso País, o que torna mais evidente e importante a criação de guia de referência para orientação aos médicos, pacientes e autoridades de saúde pública quanto à vacinação, meio efetivo e seguro no controle de determinadas doenças infecciosa. O DCNI/ABN e o BCTRIMS recomendam que os pacientes com doenças desmielinizantes do SNC (ex., EM e NMOSD) sejam constantemente monitorados, quanto a atualização do seu calendário vacinal, especialmente, no início ou antes da mudança do tratamento com uma droga modificadora de doença (DMD). É importante também salientar que as vacinas são seguras e os médicos devem estimular o seu uso em todos os pacientes. Evidentemente, deve ser dada especial atenção às vacinas com vírus vivos atenuados. Por fim, é importante que os médicos verifiquem qual DMD o paciente está em uso e quando foi feita a sua última dose, pois cada fármaco pode interagir de forma diferente com a indução da resposta imune.

ABSTRACT The Scientific Department of Neuroimmunology of the Brazilian Academy of Neurology (DCNI/ABN) and Brazilian Committee for Treatment and Research in Multiple Sclerosis and Neuroimmunological Diseases (BCTRIMS) provide recommendations in this document for vaccination of the population with demyelinating diseases of the central nervous system (CNS) against infections in general and against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19. We emphasize the seriousness of the current situation in view of the spread of COVID-19 in our country. Therefore, reference guides on vaccination for clinicians, patients, and public health authorities are particularly important to prevent some infectious diseases. The DCNI/ABN and BCTRIMS recommend that patients with CNS demyelinating diseases (e.g., MS and NMOSD) be continually monitored for updates to their vaccination schedule, especially at the beginning or before a change in treatment with a disease modifying drug (DMD). It is also important to note that vaccines are safe, and physicians should encourage their use in all patients. Clearly, special care should be taken when live attenuated viruses are involved. Finally, it is important for physicians to verify which DMD the patient is receiving and when the last dose was taken, as each drug may affect the induction of immune response differently.

Abstract The objective herein was to evaluate the effect of processing, packaging type (with and without exposure to light) and storage time on the quality of functional attributes of jelly prepared from curriola pulp. The experimental design was a completely randomized 2 × 5 factorial design, with two levels of packaging (transparent and amber) and five storage periods (0, 3, 6, 9 and 12 months). In general, the processing of curriola pulp determined a slight increase in phenolic compounds and antioxidant activity and a reduction in vitamin C content of freshly prepared jelly. The amber package and storage time promoted higher retention of bioactive compounds, mainly gallic acid, besides reducing the percentage of jelly oxidation, determined by the β-carotene / linoleic acid antioxidant method. A reduction in phenolic compounds and vitamin C was observed, which caused a reduction in the antioxidant capacity of curriola jelly. Of the five phenolic compounds identified in freshly prepared curriola jelly, gallic acid was identified as the major compound. In addition, the use of amber packaging, which prevents the incidence of light, may favor the maintenance of bioactive compounds during storage period of curriola jelly under environmental conditions.

Abstract The purpose of this study was to determine the effect of thermal vacuum processing and thermal processing without vacuum on the content of bioactive compounds and the antioxidant activity of low-calorie mixed Brazilian cerrado fruit jam. The mixed jam consisted of 60% of mixed pulp of Marolo, soursop and sweet passion fruit, and 40% other ingredients. This jam was utilized a completely randomized design to evaluate the antioxidant activity, total phenolic profile and content, carotenoid profile, and ascorbic acid content. The results showed that there was a reduction in bioactive compounds in the jam of 44.37% for total phenolics, 50.56% for ascorbic acid, 78.40% total carotenoids, and 65.14% for antioxidant activity when compared with the mixed pulps. In the carotenoid profile, reduction was observed for all compounds in relation to the mixed pulps, especially β-carotene (average loss of 81.89%). Independent of the processing, there was a significant increase in m-coumaric acid in the jam compared with the mixed pulp. The concentrations of other phenolic compounds decreased after processing. These results suggest that thermal vacuum processing is most suitable for the production of jam with higher nutritional value.

ABSTRACT Two experiments were carried out to evaluate the effects of digestible valine supplementation in pre-starter and starter diets on the productivity, nutrient metabolizability coefficient (NMC), and immune response of broilers from breeders of different ages. Experiments I and II were conducted with broilers in the pre-starter (1 to 7 days of age) and starter (8 to 21 days of age) phases, respectively. Broilers were fed diets that differed in their digestible valine content. In each trial, 400 male Cobb 500® chicks were randomly housed in a 2 × 4 factorial arrangement with eight treatments and five replicates of 10 birds each. The main effects were breeder age (37 vs. 52 weeks) and the digestible valine level in pre-starter (9.2, 10.2, 11.2, and 12.2 g/kg) and starter (8.3, 9.3, 10.3, and 11.3 g/kg) diets. Productive performance, intestinal histology, and immune response of broilers were evaluated. Supplementation with 11.2 g/kg valine in pre-starter diets improved NMC and increased villus height and villus:crypt ratio in the duodenum, jejunum development, and lymphocyte proliferation in the spleen of broilers at seven days of age, without improving performance (body weight gain, feed intake, and feed conversion ratio). In the starter phase, valine supplementation reduced feed intake but did not affect NMC, intestinal development, or immune response. The present results suggest that the same level of digestible valine should be used in the diet of broilers born to breeders of different ages, and the use of 9.2 and 8.3 g/kg digestible valine in pre-starter and starter diets, respectively, is sufficient to ensure satisfactory broiler performance. However, to improve the duodenum and jejunum development and immune response of broilers in the pre-starter phase, higher digestible valine levels are required.

OBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged <18 years) between April 11, 2020 and April 22, 2021. During this period, 102/5,951 (1.7%) of all admissions occurred in neonates, children, and adolescents. Furthermore, 3,962 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection samples were processed in patients aged <18 years, and laboratory-confirmed COVID-19 occurred in 155 (4%) inpatients and outpatients. Six/155 pediatric patients were excluded from the study. Therefore, the final group included 149 children and adolescents (n=97 inpatients and 52 outpatients) with positive SARS-CoV-2 results. RESULTS: The frequencies of sore throat, anosmia, dysgeusia, headache, myalgia, nausea, lymphopenia, pre-existing chronic conditions, immunosuppressive conditions, and autoimmune diseases were significantly reduced in children and adolescents (p<0.05). Likewise, the frequencies of enoxaparin use (p=0.037), current immunosuppressant use (p=0.008), vasoactive agents (p=0.045), arterial hypotension (p<0.001), and shock (p=0.024) were significantly lower in children than in adolescents. Logistic regression analysis showed that adolescents with laboratory-confirmed COVID-19 had increased odds ratios (ORs) for sore throat (OR 13.054; 95% confidence interval [CI] 2.750-61.977; p=0.001), nausea (OR 8.875; 95% CI 1.660-47.446; p=0.011), and lymphopenia (OR 3.575; 95% CI 1.355-9.430; p=0.010), but also had less hospitalizations (OR 0.355; 95% CI 0.138-0.916; p=0.032). The additional logistic regression analysis on patients with preexisting chronic conditions (n=108) showed that death as an outcome was significantly associated with pediatric severe acute respiratory syndrome (SARS) (OR 22.300; 95% CI 2.341-212.421; p=0.007) and multisystem inflammatory syndrome in children (MIS-C) (OR 11.261; 95% CI 1.189-106. 581; p=0.035). CONCLUSIONS: Half of the laboratory-confirmed COVID-19 cases occurred in adolescents. Individuals belonging to this age group had an acute systemic involvement of SARS-CoV-2 infection. Pediatric SARS and MIS-C were the most important factors associated with the mortality rate in pediatric chronic conditions with COVID-19.

ABSTRACT. The main purpose of this study was to evaluate the characteristics of eggs produced by Japanese quails fed with guava extract. A total of 400 eggs collected from the quails fed with experimental diets, were distributed in a completely randomized design in factorial arrangement 4 x 4 with main effects including four dietary levels of guava extract (0, 3, 6 and 9 g kg-1) and four storage periods (0, 9, 18 and 27 days) totalizing 16 treatments with five replicates of five eggs. The eggs were produced by Japanese quails, fed with experimental diets. The diets were isonutritive formulated by corn-soybean basis. The eggs were stored for different periods, at the same conditions, to constitute the treatments. The parameters evaluated were egg weight loss (g and %), yolk color, Haugh unit, specific gravity, eggshell thickness and pH of the yolk and albumen. Data were submitted to ANOVA, and means were compared using Scott-Knott test, using α = 0.05. The specific gravity of fresh eggs was better with the use of 6 g kg-1 of guava extract in the diet. The use of 3 g kg-1 of guava extract resulted in smaller eggshell thickness of fresh eggs. The Haugh unit was affected just by the storage periods. The dietary guava extract (3, 6 or 9 g kg-1) increased the pH of albumen in eggs stored for 27 days. The use of 6 g kg-1 of guava extract in quails diet increase the specific gravity in fresh eggs and increase the yolk color when the eggs are stored.

ABSTRACT This study describes difficulties in the monitoring of a child born during an oral outbreak of Chagas disease, in which there are several indications that the transmission occurred through the congenital route: 1. the mother was in the third trimester of pregnancy when she was infected; 2. She presented high parasitemia at the time of delivery; 3. In both, the mother and her daughter, T. cruzi was classified as DTU TcIV. The parasites were not found in the blood at birth and the infection was detected only three months later in an asymptomatic infant. As the mother and her child live in a highly endemic area, vector transmission could not be excluded during this period.

RESUMO Objetivou-se avaliar o efeito do extrato de goiaba em dietas de matrizes de codornas japonesas (Coturnix japonica) sobre o desempenho produtivo e a qualidade dos ovos férteis. O experimento foi realizado na Universidade Federal de Goiás. Foram utilizadas 384 matrizes de codornas Japonesas, distribuídas em 4 tratamentos, com 6 repetições, total de 12 fêmeas e 4 machos em cada repetição. Os tratamentos foram quatro níveis de extrato de goiaba nas rações (0,0%, 0,3%, 0,6% e 0,9%). O extrato de goiaba continha 2,13% de ácido elágico, considerado um princípio antioxidante da goiaba. As rações foram isonutritivas. O período experimental foi de 84 dias. Foi avaliada a produção de ovos, consumo de ração, conversão alimentar, massa de ovos, ganho de peso e qualidade interna e externa dos ovos. Os resultados foram submetidos à análise de variância e de regressão com 5% de probabilidade. A utilização do extrato de goiaba não influenciou a produção de ovos, o consumo de ração, a conversão alimentar e a massa de ovos. A altura de gema e albúmen, a unidade Haugh e o índice de gema e de albúmen diminuíram linearmente à medida em que os níveis de extrato de goiaba na ração aumentaram. O diâmetro do albúmen foi maior com 0,48% de extrato de goiaba na ração. A coloração da gema foi influenciada pela utilização do extrato, apresentando coloração mais escura com 0,498% de extrato de goiaba na ração. Conclui-se que o extrato de goiaba não melhora o desempenho e qualidade dos ovos de codornas japonesas.

SUMMARY The aim of this study was to evaluate the guava extract as an antioxidant additive in diets of Japanese quail breeders on the performance and egg’s quality. The experiment was conducted at University Federal of Goias. A total of 384 Japanese quail breeders were used, distributed in four treatments, with six replicates, with a total of 12 females and four males in each replicate. The treatments were performed with four levels of guava extract in the diets (0.0%, 0.3%, 0.6% and 0.9%). The guava extract contained the ellagic acid, considered the guava antioxidant active principle. The diets were isonutritive. Feed and water were offered ad libitum. The experimental period was 84 days. Egg production, feed intake, feed conversion ratio, egg mass, body weight variation and egg quality were evaluated. The results were submitted to analysis of variance and regression analysis. The adopted probability was 5%. Egg production, feed intake, feed conversion ratio and egg mass were not influenced by the use of guava extract. The yolk and albumen height, the Haugh Unit and the yolk and albumen index decreased linearly as the levels of guava extract in the diet increased. The diameter of the albumen was higher with the use of 0.48% of guava extract in the diet. The yolk color was affected by the guava extract, presenting a darker color with 0.50% of guava extract in the diet. It was concluded that the guava extract used as an antioxidant additive does not improve the performance and egg quality of Japanese quails.

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), became a pandemic in March 2020, affecting millions of people worldwide. However, COVID-19 in pediatric patients represents 1-5% of all cases, and the risk for developing severe disease and critical illness is much lower in children with COVID-19 than in adults. Multisystem inflammatory syndrome in children (MIS-C), a possible complication of COVID-19, has been described as a hyperinflammatory condition with multiorgan involvement similar to that in Kawasaki disease or toxic shock syndrome in children with evidence of SARS-CoV-2 infection. This review presents an update on the diagnostic methods for COVID-19, including reverse-transcriptase polymerase chain reaction (RT-PCR) tests, serology tests, and imaging, and summarizes the current recommendations for the management of the disease. Particular emphasis is placed on respiratory support, which includes noninvasive ventilation and invasive mechanical ventilation strategies according to lung compliance and pattern of lung injury. Pharmacological treatment, including pathogen-targeted drugs and host-directed therapies, has been addressed. The diagnostic criteria and management of MIS-C are also summarized.

ABSTRACT An experiment was conducted aiming to evaluate the effect of different levels of crude protein, based on the ideal protein concept and two rearing systems, on productive performance of brown laying hens. A total of 400 Hisex Brown laying hens between 30 and 45 weeks of age were distributed in a completely randomized design and a 2×4 factorial arrangement, with main effects including two rearing systems (cage and floor) and levels of crude protein (140, 150, 160, and 180 g kg−1), totalizing eight treatments. Five replicates with 10 birds each were used per experimental unit. The following parameters were evaluated: egg production, feed intake, body weight gain, feed conversion ratio, and quality traits such as dirty, cracked, or broken eggs. No interaction effect was observed between dietary protein levels and rearing systems for body weight gain, feed intake, egg production, egg weight, and feed conversion ratio. Feed intake and egg production were higher in the floor rearing system. Feed conversion ratio (kg/dz) was improved in birds reared in the cage system. The rate of cracked and broken eggs was higher in the cage system. The layers reared in the floor system produced a higher percentage of dirty eggs. The dietary protein level did not affect the evaluated parameters. Thus, we conclude that a floor rearing system is an option for layers, and the dietary protein level can be reduced up to 140 g kg−1 for Hisex Brown hens from 30 to 45 weeks of age.
