Metastatic benign leiomyoma: A case report of an uncommon presentation.

Uterine leiomyoma is a benign tumor of myometrial tissue which usually affects women of reproductive age. Its prevalence increases with age and has a peak incidence at the age of 40. Metastasizing leiomyomas are dense connective tissue and smooth myometrial muscle cells tumors located outside the uterus. We present the case report of a 55-year-old female referred to investigate pulmonary nodules with the diagnosis of metastasizing leiomyoma.

Could scalp pain be a type of unclassified headache? / A dor no couro cabeludo poderia ser um tipo de dor de cabeça não classificada?

The scalp is the structure that covers the skull. It is commonly affected by painful processes resulting from infestations, infectious or inflammatory diseases. This pain located in the scalp does not have well-defined clinical characteristics and is not yet included in the ICHD-3 diagnostic criteria. The authors suggest including this pain in the next classification of headaches as a headache attributed to a scalp disorder.

O couro cabeludo é a estrutura que cobre o crânio. É comumente acometida por processos dolorosos decorrentes de infestações, doenças infecciosas ou inflamatórias. Essa dor localizada no couro cabeludo não possui características clínicas bem definidas e ainda não está incluída nos critérios diagnósticos da ICHD-3. Os autores sugerem incluir esta dor na próxima classificação de dores de cabeça como dor de cabeça atribuída a um distúrbio do couro cabeludo.

A critical review of the Online Safety Bill.

The UK Parliament has tabled the Online Safety Bill to make the internet safer for users by requiring providers to regulate legal but harmful content on their platform. This paper critically assesses the draft legislation, surveying its rationale; its scope in terms of lawful and unlawful harms it intends to regulate; and the mechanisms through which it will be enforced. We argue that it requires further refinement if it is to protect free speech and innovation in the digital sphere. We propose four conclusions: further evidence is required to substantiate the necessity and proportionality of the Bill's interventions; the Bill risks a democratic deficit by limiting the opportunity for parliamentary scrutiny; the duties of the bill may be too wide (in terms of burdening providers); and that enforcement of a Code of Practice will likely be insufficient.

On the sui generis value capture of new digital technologies: The case of AI.

Much of the academic interest surrounding the emergence of new digital technologies has focused on forwarding the engineering literature, concentrating on the potential opportunities (economic, innovation, etc.) and harms (ethics, climate, etc.), with less focus on the foundational and theoretical shifts brought about by these technologies (e.g., what are "digital things"? What is the ontological nature and state of phenomena produced by and expressed in terms of digital products? Are there distinctions between the traditional conceptions of digital and non-digital technologies?. We investigate the question of what value is being expressed by an algorithm, which we conceptualize in terms of a digital asset, defining a digital asset as a valued digital thing that is derived from a particular digital technology (in this case, an algorithmic system). Our main takeaway is to invite the reader to consider artificial intelligence as a representation of the capture of value sui generis and that this may be a step change in the capture of value vis à vis the emergence of digital technologies.

The ethics of facial recognition technologies, surveillance, and accountability in an age of artificial intelligence: a comparative analysis of US, EU, and UK regulatory frameworks.

The rapid development of facial recognition technologies (FRT) has led to complex ethical choices in terms of balancing individual privacy rights versus delivering societal safety. Within this space, increasingly commonplace use of these technologies by law enforcement agencies has presented a particular lens for probing this complex landscape, its application, and the acceptable extent of citizen surveillance. This analysis focuses on the regulatory contexts and recent case law in the United States (USA), United Kingdom (UK), and European Union (EU) in terms of the use and misuse of FRT by law enforcement agencies. In the case of the USA, it is one of the main global regions in which the technology is being rapidly evolved, and yet, it has a patchwork of legislation with less emphasis on data protection and privacy. Within the context of the EU and the UK, there has been a critical focus on the development of accountability requirements particularly when considered in the context of the EU's General Data Protection Regulation (GDPR) and the legal focus on Privacy by Design (PbD). However, globally, there is no standardised human rights framework and regulatory requirements that can be easily applied to FRT rollout. This article contains a discursive discussion considering the complexity of the ethical and regulatory dimensions at play in these spaces including considering data protection and human rights frameworks. It concludes that data protection impact assessments (DPIA) and human rights impact assessments together with greater transparency, regulation, audit and explanation of FRT use, and application in individual contexts would improve FRT deployments. In addition, it sets out ten critical questions which it suggests need to be answered for the successful development and deployment of FRT and AI more broadly. It is suggested that these should be answered by lawmakers, policy makers, AI developers, and adopters.

In house ELISA based on recombinant ORF2 protein underline high prevalence of IgG anti-hepatitis E virus amongst blood donors in south Brazil.

Hepatitis E Virus (HEV) is a zoonotic pathogen responsible for causing acute hepatitis in human, especially in developing countries. Diagnosis of HEV usually relies on the detection of antibodies mostly by enzyme-linked immunosorbent assay (ELISA). In the present study, we designed a new indirect ELISA (iELISA) based on a short recombinant peptide derived from the capsid protein (ORF2p) and demonstrated its potential for detecting human IgG against HEV genotype 3. The best polystyrene plate (Maxisorp®), optimal ORF2p coating antigen concentration (0,67µg/well) and primary antibody dilution (1:100) were determined. This iELISA showed a sensitivity of 91.4% and specificity of 95.9%. The comparison of our in house iELISA with a commercial assay (RecomWell, Mikrogen®) showed 94.25% of agreement and a kappa index of 0.88. The ORF2 recombinant ELISA was used to screen 780 blood donors for anti-HEV IgG and we found that 314 (40,25%) of these donors were IgG positive. This high prevalence of antibodies suggests, for the first time, that the Southern Brazil region might be endemic to Hepatitis E Virus genotype 3.

Métodos: Busca de registros nos prontuários de pacientes com diagnóstico de LMA no período de janeiro de 2009 a dezembro de 2014. Mensurou-se o perfil citogenético da amostra, estratificando-a por faixa etária e classificação conforme FAB e OMS para posterior correlação dos dados de prognóstico e distribuição epidemiológica obtidos com os dados disponíveis na literatura médica atual. Resultados: Foram selecionados 38 pacientes para análise, com idades entre 1 e 84 anos. Todos os pacientes possuíam cariotipagem e 76,3% apresentavam alterações citogenéticas; 13 pacientes apresentavam cariótipo favorável (CF), 14, cariótipo intermediário (CI), 10, cariótipo desfavorável (CD) e 1 apresentava LMA secundária. No grupo com CF, a média de idade foi de 25 anos (p=0,0151); no grupo com CD, foi de 39,8%. No grupo com CF, 69,2% obtiveram remissão completa com protocolo de tratamento; no grupo com CI, 18,18% obtiveram a remissão completa, e por fim, no grupo com CD nenhum caso obteve remissão completa. Houve tendência à plaquetopenia mais significativa no grupo com CI. Conclusão: Ficou nítida a correlação das alterações citogenéticas observadas com sua respectiva importância prognóstica, corroborando a necessidade da determinação do cariótipo para o adequado manejo dos pacientes com LMA (AU)

Introduction: An analysis of the cytogenetic profile of patients with acute myeloid leukemia (AML) and correlation with clinical and epidemiological data and their respective prognoses. Methods: Search of records in the medical charts of patients diagnosed with AML from January 2009 to December 2014. The cytogenetic profile of the sample was measured by stratifying it by age group and classification according to FAB and WHO for subsequent correlation of prognostic and epidemiological distribution data obtained from the available data of the medical literature. Results: Thirty-eight patients were selected for analysis, ranging from 1 to 84 years of age. All patients had karyotyping and 76.3% presented cytogenetic alterations; 13 patients had favorable karyotype (FK), 14 intermediate karyotype (IK), 10 unfavorable karyotype (UK), and 1 had secondary AML. In the FK group, the mean age was 25 years (p = 0.0151); in the UK group, 39.8%. In the FK group, 69.2% achieved complete remission with treatment protocol; in the IK group, 18.18% had complete remission, and finally, in the UK group, no case achieved complete remission. There was a trend towards more significant thrombocytopenia in the IK group. Conclusion: The correlation of the observed cytogenetic changes with their respective prognostic importance was clear, corroborating the need to determine the karyotype for an adequate management of patients with AML (AU)

Letramento e Compreensão de Textos: análise de desempenho de estudantes do 1º ano do ensino fundamental / Literacy and Text Comprehension: analysis of first grade student’sperformance

Considerando a compreensão de textos como indicador de letramento, o presente trabalho analisou o desempenho de 30 estudantes do 1º ano do ensino fundamental em uma tarefa com dez gêneros textuais escolhidos por serem considerados próximos ao cotidiano das crianças, evidenciando o letramento social. Para sua realização, os textos foram gravados em áudio, pois algumas crianças nesta faixa etária não eram alfabetizadas. Após ouvir cada gênero textual, foram realizadas uma pergunta inferencial causal e outra de estado. As respostas foram categorizadas como não responde, responde de forma incoerente e responde de forma coerente. Observou-se que a maioria dos estudantes responderam as perguntas mesmo que não tenham compreendido o texto, exemplo disto é a alta frequência na categoria II - responde de forma incoerente (N=357). Os resultados indicam que alguns gêneros textuais não eram tão próximos do cotidiano das crianças, como a notícia. É possível que isso tenha ocorrido porque os estudantes não fazem uso desse gênero em suas práticas sociais. Este trabalho contribui ao considerar a compreensão de textos como indicador do letramento e por utilizar gêneros próximos ao cotidiano das crianças. Além do que, o estudo pode ser realizado com participantes não alfabetizados, como ocorreu nesta pesquisa.

Considering the comprehension of texts as an indicator of literacy, this study analysed the performance of 30 students from 1st grade of primary education in a task with ten textual genres chosen by considering their proximity to the daily lives of the children, highlighting the social literacy. To accomplish this, the texts were recorded in audio since some children in this age group were illiterate. After listening to each textual genre, a causal inference question and another of state were made. Responses were categorized as not responding, responds incoherently and responds coherently. It was observed that most of thestudents answered the questions even when they could not understand the text, an evidence of this, is the high frequency of category II (N= 357). The results indicate that some textual genres were not so proximate to the daily lives of the children, as the news. It is possible that this has taken nplace because students do not make use of this kind of text in their social practices. This work can bring contributions once it considers the comprehension of texts as an indicator of literacy and also for usinggenres near to the daily lives of the children. In addition, the study can be conducted with illiterate participants, as occurred in this study.

Minerals consumption by Acetobacter xylinum on cultivation medium on coconut water.

The objective of this work is to verifying the consume of the minerals K, Na, Fe, Mg, P, S-SO4 (-2), B, N Total Kjedahl (NTK), NO3 (-)-N, and NH4 (+)-N in the production of bacterial cellulose by Acetobacter xylinum, according to the medium and the manner of cultivation. The fermentative process was in ripe and green coconut water. K and Na were determined by flame emission photometry, Mg and Fe by atomic absorption spectrophotometry, P by molecular absorption spectrophotometry, S-SO4 (-2) by barium sulphate turbidimetry, B by Azomethin-H method, NTK by Kjeldahl method, N-NO3 (-) and N-NH4 (+) by vapor distillation with magnesium oxide and Devarda's alloy, respectively. In Fermentation of ripe coconut water there were higher consumption of K (69%), Fe (84,3%), P (97,4%), S-SO2 (-2) (64,9%), B (56,1%), N-NO3 (-) (94,7%) and N-NH4 (+) (95,2%), whereas coconut water of green fruit the most consumed ions were Na (94,5%), Mg (67,7%) and NTK (56,6%). The cultivation under agitation showed higher mineral consumption. The higher bacterial cellulose production, 6 g.L(-1), was verified in the coconut water fermentative in ripe fruit, added KH2PO4, FeSO4 and NaH2PO4 kept under agitation.
