Lactobacilli and bifidobacteria in the feces of schoolchildren of two different socioeconomic groups: children from a favela and children from a private school

OBJECTIVE: To determine the number of lactobacillus and bifidobacterium colonies in the feces of schoolchildren from two different socioeconomic levels. METHODS: We analyzed fecal samples of children aged 6 to 10 years without gastrointestinal symptoms or recent use of antimicrobials. The first group included 86 children living in a favela in the city of Osasco, state of São Paulo, southeastern Brazil. The second group included 36 children attending a private school in the same city. Body mass index (BMI) was used to assess nutritional status according to the reference values of the National Center for Health Statistics (NCHS). Specific anaerobic culture media were used for isolation of colonies for 48 and 72 hours at 37 °C. The number of colonies was determined using the plate-counting method. RESULTS: The mean lactobacillus (1.125 x 10(9) colony-forming units, CFU/g) and bifidobacterium (1.675 x 10(9) CFU/g) counts in the private school group were higher (p -1.0 SD (n = 57): 0.350 x 10(9) and 0.420 x 10(9) CFU/g, respectively. CONCLUSION: The microbiota of schoolchildren living in unfavorable environmental conditions shows lower numbers of fecal lactobacillus and bifidobacterium colonies, especially in children with lower BMI values.OBJETIVO: Determinar o número de colônias de lactobacilos e bifidobactérias nas fezes de crianças escolares, pertencentes a dois estratos socioeconômicos. MÉTODOS: Foram analisadas amostras de fezes de crianças com idade entre 6 e 10 anos sem sintomas gastrointestinais ou uso recente de antimicrobianos. O primeiro grupo foi constituído por 86 crianças, moradoras em uma favela localizada no município de Osasco (SP). O segundo grupo foi constituído por 36 crianças matriculadas em uma escola particular da mesma cidade. O estado nutricional foi avaliado usando o índice de massa corporal (IMC) de acordo com os valores de referência do National Center for Health Statistics (NCHS). O isolamento das colônias foi realizado em meios de cultura específicos em anaerobiose, durante 48 e 72 horas a 37 °C. A determinação do número foi feita pelo método da contagem em placa. RESULTADOS: A mediana de lactobacilos (1,125 x 10(9) unidades formadoras de colônia, UFC/g) e bifidobactérias (1,675 x 10(9) UFC/g) na escola particular foi superior (p -1,0 desvio padrão (n = 57): 0,350 x 10(9) e 0,420 x 10(9) UFC/g, respectivamente. CONCLUSÃO: A microbiota de crianças escolares que moram em condições ambientais desfavoráveis apresenta menor número de colônias de lactobacilos e bifidobactérias nas fezes, especialmente naquelas com menores valores do IMC.Universidade Federal de São Paulo (UNIFESP) Departamento de PediatriaUNIFESP Departamento de PediatriaCentro Universitário Fundação e Instituto de Educação de Osasco Departamento de Ciências da Saúde Instituto de Pesquisa UnolabUNIFIEO Departamento de Ciências da Saúde Instituto de Pesquisa UnolabUNIFIEO Departamento de PediatriaUNIFESP Departamento de Microbiologia, Imunologia e ParasitologiaUNIFESP, Depto. de PediatriaUNIFESP, Depto. de PediatriaUNIFESP, Depto. de Microbiologia, Imunologia e ParasitologiaSciEL

Acute Liver Failure In A Term Neonate After Repeated Paracetamol Administration.

Severe hepatotoxicity caused by paracetamol is rare in neonates. We report a case of paracetamol-induced acute liver failure in a term neonate. A 26-day-old boy was admitted with intestinal bleeding, shock signs, slight liver enlargement, coagulopathy, metabolic acidosis (pH=7.21; bicarbonate: 7.1 mEq/L), hypoglycemia (18 mg/dL), increased serum aminotransferase activity (AST=4,039 IU/L; ALT=1,087 IU/L) and hyperbilirubinemia (total: 9.57 mg/dL; direct: 6.18 mg/dL) after receiving oral paracetamol (10 mg/kg/dose every 4 hours) for three consecutive days (total dose around 180 mg/kg; serum concentration 36-48 hours after the last dose of 77 µg/ mL). Apart from supportive measures, the patient was successfully treated with intravenous N-acetylcysteine infusion during 11 consecutive days, and was discharged on day 34. The follow-up revealed full recovery of clinical and of laboratory findings of hepatic function. The paracetamol pharmacokinetics and pharmacodynamics in neonates and infants differ substantially from those in older children and adults. Despite the reduced rates of metabolism by the P-450 CYP2E1 enzyme system and the increased ability to synthesize glutathione--which provides greater resistance after overdoses--, it is possible to produce hepatotoxic metabolites (N-acetyl-p-benzoquinone) that cause hepatocellular damage, if glutathione sources are depleted. Paracetamol clearance is reduced and the half-life of elimination is prolonged. Therefore, a particular dosing regimen should be followed due to the toxicity risk of cumulative doses. This report highlights the risk for severe hepatotoxicity in neonates after paracetamol multiple doses for more than two to three days.32144-

Antifungal Potential of Copper(II), Manganese(II) and Silver(I) 1,10-Phenanthroline Chelates Against Multidrug-Resistant Fungal Species Forming the Candida haemulonii Complex: Impact on the Planktonic and Biofilm Lifestyles

Candida haemulonii, Candida haemulonii var. vulnera and Candida duobushaemulonii, which form the C. haemulonii complex, are emerging etiologic agents of fungal infections known to be resistant to the most commonly used antifungals. The well-established anti-Candida potential ofmetal complexes containing 1,10-phenanthroline (phen) ligands encouraged us to evaluate different copper(II), manganese(II), and silver(I) phen chelates for their ability to inhibit planktonic growth and biofilm of C. haemulonii species complex. Two novel coordination complexes, {[Cu(3,6,9-tdda)(phen)2].3H2O.EtOH}n and [Ag2(3,6,9-tdda)(phen)4].EtOH (3,6,9-tddaH2 = 3,6,9-trioxaundecanedioic acid), were synthesized in a similar fashion to the other, previously documented, sixteen copper(II), manganese(II), and silver(I) chelates employed herein. Three isolates of each C. haemulonii species complex were used and the effect of the metal chelates on viability was determined utilizing the CLSI standard protocol and on biofilm-growing cells using the XTT assay. Cytotoxicity of the chelates was evaluated by the MTT assay, employing lung epithelial cells. The majority of the metal chelates were capable of interfering with the viability of planktonic-growing cells of all the fungal isolates

Atlantic mammal traits: a dataset of morphological traits of mammals in the atlantic forest of south America

Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species, but also within species. Mammals are an interesting group for investigating trait-based approaches because they play diverse and important ecological functions (e.g., pollination, seed dispersal, predation, grazing) that are correlated with functional traits. Here we compile a data set comprising morphological and life history information of 279 mammal species from 39,850 individuals of 388 populations ranging from −5.83 to −29.75 decimal degrees of latitude and −34.82 to −56.73 decimal degrees of longitude in the Atlantic forest of South America. We present trait information from 16,840 individuals of 181 species of non-volant mammals (Rodentia, Didelphimorphia, Carnivora, Primates, Cingulata, Artiodactyla, Pilosa, Lagomorpha, Perissodactyla) and from 23,010 individuals of 98 species of volant mammals (Chiroptera). The traits reported include body mass, age, sex, reproductive stage, as well as the geographic coordinates of sampling for all taxa. Moreover, we gathered information on forearm length for bats and body length and tail length for rodents and marsupials. No copyright restrictions are associated with the use of this data set. Please cite this data paper when the data are used in publications. We also request that researchers and teachers inform us of how they are using the data.Fil: Gonçalves, Fernando.

GEOSTATISTICAL TECHNIQUES AND SPATIAL INTERPOLATORS IN THE STRATIFICATION OF Eucalyptus sp. STANDS

Os objetivos deste estudo foram verificar a possibilidade do uso da estrutura de depend \ueancia espacial para a defini\ue7\ue3o de estratos em povoamentos florestais e comparar, com base no erro de amostragem, a Amostragem Casual Simples (ACS) e a Amostragem Casual Estratificada (ACE), sendo a estratifica\ue7\ue3o realizada por meio dos interpoladores espaciais Inverso do Quadrado da Dist \ue2ncia (IQD) e Krigagem. Os dados utilizados foram provenientes de invent\ue1rios convencionais realizados nos anos de 2006 e 2007, em projetos localizados nos munic \uedpios de Curvelo, Jo\ue3o Pinheiro e Montes Claros, Minas Gerais. Os resultados mostraram que, dos 50 projetos, 64 % apresentaram grau de depend \ueancia espacial de m \ue9dio a forte, evidenciando que o uso de m \ue9todos geoestat \uedsticos possibilita redu\ue7\ue3o no erro sem aumento de custo no invent\ue1rio. A estratifica\ue7\ue3o com base no interpolador IQD utilizada nos projetos que apresentaram fraco grau de depend \ueancia espacial (DE) contribuiu para uma redu\ue7\ue3o em m \ue9dia de 68,4 % no erro de amostragem. A utiliza\ue7\ue3o do interpolador geoestat \uedstico nos projetos que apresentaram de m \ue9dia a forte DE, contribuiu para uma redu\ue7\ue3o m \ue9dia de 47,0 % e 65,7 % no erro de amostragem, respectivamente. Mesmo nos projetos onde a estrutura de depend \ueancia espacial se manifestou, a estratifica\ue7\ue3o com base no interpolador IQD gera melhoria das estimativas da ACE em rela\ue7\ue3o \ue0 ACS.The objectives of this study were to verify the possibility of application of the spatial dependence structure for stratus definition in forest stands and to compare, based on the sampling error, Random Sampling Design (ACS) and Stratified Sampling Design (ACE), being the stratification realized by the spatial interpolators Inverse of Square of Distance (IQD) and Kriging. The data was provided from conventional inventories conducted in the years of 2006 and 2007, in clonal eucalypt stands on projects located in Curvelo, Jo\ue3o Pinheiro and Montes Claros Counties, in Minas Gerais state. The results showed that, of the 50 projects, 64 % presented medium or high spatial dependence degree, evidencing that geo-statistical methods reduce the error without increasing the costs in the inventory. The stratification based on IQD which was used in the projects with low spatial dependence degree (DE) contributed for a mean reduction of 68.4 % in the sampling error. The use of the kriging in the projects with medium or high DE, contributed for a mean reduction of 47.0 % and 65.7 % in the sampling error, respectively. Even in the projects where the spatial dependence structure was detected, the stratification based on IQD generates improvement of the estimates in the ACE compared to the ACS

Agreement between scales for screening and diagnosis of motor development at 6 months

OBJECTIVE: To ascertain the degree of agreement between a score for screening and another for diagnosis of motor development in 6-month old infants and to define the most appropriate cutoff point for screening. METHODS: A sectional study, enrolling asymptomatic full term newborns with gestational ages from 37 to 41 weeks, who were discharged from the maternity unit 2 days after birth and are resident in the Campinas area. Infants were excluded if they presented genetic syndromes, malformations, congenital infections, intensive care admission or low birth weight. The assessment instruments investigated were the Alberta Infant Motor Scale (AIMS) and the Bayley Scales of Infant Development II (BSID-II). Two cutoff points were evaluated for the AIMS, the 5th and 10th percentiles, and for the BSID-II infants were classified according to its motor index score (IS) as having inadequate (IS 85, above the mean minus 1 standard deviation). RESULTS: The study sample comprised 43 infants. Six infants (14.00%) exhibited inadequate motor performance. Using the BSID-II motor classification and the 5th percentile AIMS cutoff, sensitivity was 100%, specificity 78.37%, accuracy 81.39%, kappa index 0.50 and p 85, maior ou igual a menos 1 desvio padrão da média). RESULTADOS: A amostra foi constituída por 43 lactentes. Seis lactentes (14,00%) apresentaram desempenho motor inadequado. Considerando a classificação motora das BSID-II e o percentil 5 da AIMS, obteve-se sensibilidade = 100%, especificidade = 78,37%, acurácia = 81,39%, índice kappa = 0,50 e p < 0,001; considerando a classificação motora das BSID-II e o percentil 10 da AIMS, obteve-se sensibilidade = 100%, especificidade = 48,64%, acurácia = 55,81%, índice kappa = 0,20 e p = 0,025. CONCLUSÕES: Os resultados sugerem boa concordância entre os instrumentos de avaliação no sexto mês. A melhor combinação para os parâmetros analisados é a utilização do percentil 5 da AIMS.47047

Preferences for menu labelling formats of young adults in Brazil and in the United Kingdom

Objective This pilot study was aimed at exploring preferences of young adults in two different contexts on restaurant menu labelling formats. Methods Five focus groups were conducted with 36 participants, two focus groups with 11 participants in Brazil and three focus groups with 25 in the United Kingdom. Themes originating from the content analysis of the transcriptions were organised around four possible menu labelling formats: 1) numerical information on calories; 2) numerical information on calories and nutrients; 3) traffic light system plus Guideline Daily Amounts; 4) food information with ingredients list plus highlighted symbols. Results In both countries, participants preferred the ingredients list plus symbols format, considered more comprehensive and useful to make an informed food choice. Organic food and vegetarian symbols were the ones considered most important to appear on restaurant menu labels with ingredients list. However, most participants in Brazil and in the United Kingdom rejected the information restricted to calories and calories plus nutrients formats, saying that these would not influence their own choices. Conclusion This is the first multicultural qualitative study exploring preferences of people living in different countries with different eating habits, but where menu labelling is voluntary. Results evidenced similarities in participants' likes and dislikes for menu labelling formats in these two different contexts. Discussions showed participants in both countries prefer qualitative information than numerical information, suggesting that ingredients list and symbols provide information that people want to see on the menu

Genetic diversity of NS5A protein from hepatitis C virus genotype 3a and its relationship to therapy response

<p>Abstract</p> <p>Background</p> <p>The quasispecies nature of HCV may have important implications for viral persistence, pathogenicity and resistance to antiviral agents. The variability of one of the viral proteins, NS5A, is believed to be related to the response to IFN therapy, the standard treatment for infection. In this study we analyzed the quasispecies composition of NS5A protein in patients infected with HCV genotype 3a, before IFN therapy.</p> <p>Methods</p> <p>Viral RNA was isolated from samples of 12 patients: four sustained virological responders (SVR), four non-responders (NR), and four end-of-treatment responders (ETR). cDNA was synthesized, the NS5A region was amplified and the fragments obtained were cloned. Fifteen clones from each patient were sequenced with eight primers, generating 179 contigs.</p> <p>Results</p> <p>Higher values for substitution (either synonymous or non-synonymous) and for distance were found in the SVR group. However, the NR group showed relatively more non-synonymous mutations than the other groups, owing to the higher values of dN/dS in complete NS5A and most specific regions. Overall, NS5A protein is undergoing purifying selection, since all dN/dS ratios values are below 0.5.</p> <p>Conclusions</p> <p>Our study provides an overview of the genetic variability of complete NS5A protein in HCV genotype 3a.</p

In Vitro and In Vivo Investigation of the Efficacy of Arylimidamide DB1831 and Its Mesylated Salt Form - DB1965 - against Trypanosoma cruzi Infection

Chagas disease is caused by infection with the intracellular protozoan parasite Trypanosoma cruzi. At present, nifurtimox and benznidazole, both compounds developed empirically over four decades ago, represent the chemotherapeutic arsenal for treating this highly neglected disease. However, both drugs present variable efficacy depending on the geographical area and the occurrence of natural resistance, and are poorly effective against the later chronic stage. As a part of a search for new therapeutic opportunities to treat chagasic patients, pre-clinical studies were performed to characterize the activity of a novel arylimidamide (AIA - DB1831 (hydrochloride salt) and DB1965 (mesylate salt)) against T.cruzi. These AIAs displayed a high trypanocidal effect in vitro against both relevant forms in mammalian hosts, exhibiting a high selectivity index and a very high efficacy (IC50 value/48 h of 5–40 nM) against intracellular parasites. DB1965 shows high activity in vivo in acute experimental models (mouse) of T.cruzi, showing a similar effect to benznidazole (Bz) when compared under a scheme of 10 daily consecutive doses with 12.5 mg/kg. Although no parasitological cure was observed after treating with 20 daily consecutive doses, a combined dosage of DB1965 (5 mg/kg) with Bz (50 mg/kg) resulted in parasitaemia clearance and 100% animal survival. In summary, our present data confirmed that aryimidamides represent promising new chemical entities against T.cruzi in therapeutic schemes using the AIA alone or in combination with other drugs, like benznidazole
