Abstract
RESUMO Objetivo: analisar o sentido da rede social de adolescentes que cumprem Liberdade Assistida e identificar os componentes essenciais dessa rede. Método: estudo exploratório, de abordagem qualitativa. Participaram do estudo 26 adolescentes com idade de 13 a 18 anos. Para a coleta dos dados, optou-se por entrevista semiestruturada e construção de mapas de rede. Resultados: evidenciou-se a essencialidade da rede social para os adolescentes, destacando-se a importância da família - especialmente a mãe -, e do Centro de Referência Especializado de Assistência Social, para promoção social e construção de um novo projeto de vida, sem envolvimento com atos infracionais. Todavia, os adolescentes não revelaram vínculos com profissionais de saúde. Conclusão: observou-se a necessidade do enfermeiro, enquanto profissional da atenção primária à saúde, atuar de forma intersetorial e interdisciplinar, no sentido de fortalecer a rede social de adolescentes em conflito com a lei.

Abstract
Abstract
Background:African Americans (AA) have a higher mortality associated with breast cancer (BC) when compared to Caucasians (CC).This has been attributed to diverse factors that include access to care, reproductive factors and different somatic genomic profiles. We aimed to compare the racial mutational landscape of 565 BC samples.
Methods:DNA from formalin-fixed paraffin-embedded samples was sequenced using the Illumina NextSeq (Agilent SureSelect XT, 592 gene selected based on COSMIC database) and MiSeq (TruSeq, 47 gene) for mutation and gene amplification analyses. Protein expression was evaluated by Immunohistochemistry (IHC). The exome aggregation consortium database was assessed for known ethnicity associations.
Results:Tumor samples from 118 AA and 447 CC female patients were included in this analysis. AA were younger (median age 56 vs58y, p0.005) and had higher proportion of triple negative BC (TNBC) (32% vs17%, p0.001). 50.3% of the samples were obtained from primary tumors and the remainder from metastatic sites. This was similar in AA and CC (48.8% vs51.8% primary tumors, pNS). The two genes with highest mutation prevalence were TP53 and PIK3CA. AA had fewer PIK3CA mutations (14.7% vs28.2%, p0.03). Within HR+/HER2+ and HR+/HER2- subtypes there was a similar trend in the number of PIK3CA mutations but it was no longer significant. The remainder mutation analysis did not differ between races. In terms of protein expression there were significant differences in the androgen receptor(AR), RRM1, EGFR and TS expression (table). AR positivity defined as ≥10% was less frequent in AA (40.0% vs60.4%, p0.0001 and when adjusted for age, p0.005) and associated with PIK3CA mutations in both AA and CC (p0.01 and p0.007). AR expression in TNBC was positive in 17.8% of CC and 5.4% of AA (pNS). Copy number variation (CNV) data assessed by NextGen revealed significantly higher gene copy number in AA compared to CC in CCND1 (16% vs4%, p0.04), FGF19 (16% vs1.3%, p0.01) and FGF4 (16% vs3%, p0.02). When only TNBC was considered, RRM1, TOPO1 and TUBB3 expression was significantly higher in AA than CC (table) and there were no differences in the mutational analyses. Evaluation of other BC subtypes (HER2, HR positive) is currently underway.
Conclusions:In this large cohort of AA who underwent genomic profiling there were relatively few differences in the mutation analysis compared to CC. The only significant difference seen was the lower number of PIK3CA mutations in AA, which had been previously reported in a cohort of 105 AA from the TCGA data (Keenan et al. JCO 2015). Protein expression by IHC revealed lower expression of AR in AA, even after adjustment for age, which could have therapeutic implications. Some of the racial differences found in the molecular landscape of BC including PIK3CA mutations, AR, EGFR expression and CNV may contribute to a more aggressive tumor biology in AA.

Abstract
Bunyamwera virus (BUNV) (Bunyaviridae, genus Orthobunyavirus, serogroup Bunyamwera) is considered an emerging pathogen for humans and animals in American countries. The CbaAr-426 strain of BUNV was recovered from mosquitoes Ochlerotatus albifasciatus (Diptera: Culicidae) collected in Córdoba province (Argentina), where serological studies detected high seroprevalences in humans and animals. Molecular detection of Orthobunyavirus was performed in mosquitoes collected in Córdoba province. Seventeen mosquito pools of Oc. albifasciatus, Ochlerotatus scapularis and Culex quinquefasciatus (Diptera: Culicidae) showed positive results; four of these positive pools, all of Oc. scapularis, were sequenced. All amplicons grouped with BUNV in the Bunyamwera serogroup. The findings highlight the circulation of BUNV in Córdoba province and represent the first report of BUNV-infected Oc. scapularis mosquitoes in Argentina.

Abstract
The objective of this study was to compare the perceptions of two families living in two different neighborhoods (rated according to risk levels) regarding social support. A questionnaire was designed to assess social support according to the following dimensions: instrumental, emotional, religious, and support from friends, neighbors and family. The sample was comprised as follows: considering the 114 families living in neighborhood 1, 52 families were interviewed; and among the 162 families living in neighborhood 2, 60 families were interviewed. No significant difference was found related to instrumental, religious and emotional support, including the support from relatives among the families from both neighborhoods. The results disagree with the reviewed literature, which indicated a strong association between social support and families living at socioeconomic risk. In conclusion, social support is important for families, regardless of their risk stratification.

Abstract
This paper reports on the ferromagnetic properties of aged Ti(1-x)CoxO(2-delta) anatase nanopowders with different Co contents (0.03 < or = x < or = 0.10). It is shown for the first time that aged Co:TiO2 anatase samples retain rather high values of magnetization (M), remanence (Mr) and coercivity (Hc) which provide strong evidence for a preserved long-range ferromagnetic order. Room temperature M, Mr and Hc values were measured in the ranges of [0.05, 0.79] microB/Co, [0.044, 0.096] microB/Co and [366.7,494.8]Oe, respectively, which are in the same range as in general reported either for newly prepared thin films or nanoparticles.

Abstract
The benzidine photodegradation process was studied using UV/Vis spectroscopy and electrospray ionization mass spectrometry (ESI-MS) combined with collision-induced dissociation (CID) and tandem mass spectrometry (MS/MS). Mass spectrometry was used to characterize benzidine and to identify and characterize possible degradation products and intermediates. The MS data showed that benzidine is quite persistent in aqueous medium. Moreover, the MS analysis enabled us to propose the following three degradation products/intermediates: 4'-nitro-4-biphenylamine, tetrahydroxybiphenyl and 4,4'-dinitrobiphenyl. For the benzidine molecular ion and protonated molecule and for the protonated molecules of the degradation products/intermediates detected, fragmentation patterns are proposed based on CID and MS/MS data. For the photodegradation process different catalysts were used, namely the commercial TiO2 Degussa P25, and the laboratory-prepared ZnO, TiO2 anatase and a titanium-zinc oxide with a perovskite type structure. Comparison of the different catalysts showed that degradation was favoured with the commercial TiO2. Nevertheless, the other catalysts appear to be promising and economic alternatives for potential future remediation studies.

Abstract
In the final of November 1994, an outbreak of a febrile disease was observed in the Serra Pelada gold mine (5 degrees 35'S: 49 degrees 30'W) in the Southeast region of Pará State. Twenty samples were collected and sent to the laboratory of Arbovirus of Instituto Evandro Chagas. The tests showed that the disease was caused by Oropouche virus (Bunyaviridae, Bunyavirus, Simbu serological group). Between 8-22 December 296 serum samples were taken (54 from febrile patients, 16 paired samples and 242 from contacts and convalescent patients) of the 73 familiar groups. From febrile patients, ten Oropouche virus strains were obtained. From paired serum, six seroconversions were obtained and 242 other Oropouche infections were diagnosed by HI and MAC ELISA. The clinical-picture of febrile disease accompanied by severe bedache, chills, myalgia, photophobia retrobulbar pain and malaise was observed. Involvement of central nervous system was not observed. Based on the serological data, we estimated that in the outbreak of Serra Pelada around 5,000 cases occurred corresponding to a prevalence of 83%.
