A EFICÁCIA DAS REDES DE COOPERAÇÃO JURÍDICA DIRETA NO COMBATE À CORRUPÇÃO TRANSNACIONAL E SUA CONCRETIZAÇÃO PELO SISTEMA PROCESSUAL BRASILEIRO: NOTAS SOBRE A OPERAÇÃO LAVA-JATO.

Inseridos na área de concentração Justiça, Processo e Constituição, na linha de pesquisa Processo, Constitucionalidade e Tutela de Direitos Existenciais e Patrimoniais do Mestrado em Direito Processual da Universidade Federal do Espírito Santo, os estudos foram desenvolvidos a partir de contribuições dos Grupos de Pesquisa intitulados O Direito Internacional e o Labirinto da Codificação e Limites e Extensão da Jurisdição Internacional Brasileira. A partir da premissa da problemática da corrupção, compreendida como fenômeno de mercadejo da função pública visando à obtenção de vantagens indevidas, busca-se combater a expansão de suas práticas na comunidade globalizada, sob a ótica procedimental da realização da cooperação jurídica internacional. Por meio do método indutivo de investigação, adota-se como referencial particular o recorte fático extraído da Ação Penal nº 5036528-23.2015.4.04.7000, em trâmite perante a 13ª Vara da Seção Judiciária Federal do Paraná, com o objetivo de verificar a aplicação das redes transnacionais para sustentar o intercâmbio de dados, informações e elementos de prova, in casu. A partir da análise do caso concreto, propõe-se a construção de um conhecimento geral sobre a eficácia da aplicação de instrumentos de cooperação penal para o enfrentamento da corrupção em dimensão transnacional e sua concretização pelo sistema processual brasileiro, com especial enfoque nas redes de cooperação direta. Assentada na linha de pensamento do Pluralismo Jurídico Transnacional, adota-se a concepção do Direito Global fundada na formação de discursos e redes de comunicação, enquanto o reflexo de arranjos nos quais se associam multifaces jurídicas e se agregam feixes normativos emitidos a partir de diversificados corpos comunicantes, integrando um espectro de transnacionalidade. O estudo se baseia na ação coletiva de redes transnacionais e de arranjos cooperativos entre autoridades reguladoras nacionais. Outrossim, são lançadas as bases especificamente no necessário respeito aos direitos fundamentais da pessoa humana e sua assunção como limite e paradigma democrático da atuação das redes de cooperação para combater práticas delituosas na comunidade global hodierna. Por fim, serão realizados apontamentos acerca da confirmação ou não da hipótese da pesquisa, para o fim de determinar se tais redes são eficazes no combate à corrupção e se são concretizadas no sistema processual brasileiro, traçando as respectivas notas sobre a aplicação das redes de cooperação direta na Operação Lava Jato.

Langerhans cell histiocytosis of the suprasellar region: diagnosis based on thyroid cytology.

Langerhans cell histiocytosis (LCH) may present as unifocal disease of the suprasellar region, with symptoms and signs of hypopituitarism, arginine vasopressin deficiency (AVP-D), and weight gain. Transcranial biopsy is necessary to define diagnosis and guide treatment decisions, but it is associated with significant morbidity. We describe a patient with Hashimoto thyroiditis and a single hypothalamic mass in whom LCH diagnosis was made by thyroid fine-needle aspiration cytology (FNAC) performed despite nonspecific findings in thyroid imaging, on the basis of a slightly elevated [18F]-fluorodeoxyglucose (FDG) avidity on PET/CT and volume increase during follow-up

A digital self-management intervention for adults with type 2 diabetes: Combining theory, data and participatory design to develop HeLP-Diabetes

Background Digital health interventions have potential to contribute to better health outcomes, better healthcare and lower costs. However, evidence for their effectiveness is variable. The development and content of digital health interventions are often not described in enough detail to enable others to replicate the research or improve on previous interventions. This has led to a call for transparent reporting of intervention content and development. Purpose To describe the development process and content of a digital self-management intervention for people with type 2 diabetes (HeLP-Diabetes) that has been found to achieve its target clinical outcome, the reduction of HbA1c, a measure of glycaemic control. Method We synthesised theory, data from existing research evidence and international guidelines, and new qualitative data from target users to identify the determinants of self-management and the content to be included in HeLP-Diabetes. Using an ongoing iterative participatory design approach the content of the intervention was written, produced, reviewed and changed. Conclusion It is possible to develop and transparently report self-management programmes for long-term conditions, which reflect current best evidence, theoretical underpinning and user involvement. We intend that reporting the development process and content will inform future digital intervention development

R534C mutation in hERG causes a trafficking defect in iPSC-derived cardiomyocytes from patients with type 2 long QT syndrome

Patient-specific cardiomyocytes obtained from induced pluripotent stem cells (CM-iPSC) offer unprecedented mechanistic insights in the study of inherited cardiac diseases. The objective of this work was to study a type 2 long QT syndrome (LQTS2)-associated mutation (c.1600C > T in KCNH2, p.R534C in hERG) in CM-iPSC. Peripheral blood mononuclear cells were isolated from two patients with the R534C mutation and iPSCs were generated. In addition, the same mutation was inserted in a control iPSC line by genome editing using CRISPR/Cas9. Cells expressed pluripotency markers and showed spontaneous differentiation into the three embryonic germ layers. Electrophysiology demonstrated that action potential duration (APD) of LQTS2 CM-iPSC was significantly longer than that of the control line, as well as the triangulation of the action potentials (AP), implying a longer duration of phase 3. Treatment with the IKr inhibitor E4031 only caused APD prolongation in the control line. Patch clamp showed a reduction of IKr on LQTS2 CM-iPSC compared to control, but channel activation was not significantly affected. Immunofluorescence for hERG demonstrated perinuclear staining in LQTS2 CM-iPSC. In conclusion, CM-iPSC recapitulated the LQTS2 phenotype and our findings suggest that the R534C mutation in KCNH2 leads to a channel trafficking defect to the plasma membrane.Fil: Mesquita, Fernanda C.

Adherence to secondary prophylaxis and disease recurrence in 536 Brazilian children with rheumatic fever

<p>Abstract</p> <p>Background</p> <p>More than 15 million people worldwide have rheumatic fever (RF) and rheumatic heart disease due to RF. Secondary prophylaxis is a critical cost-effective intervention for preventing morbidity and mortality related to RF. Ensuring adequate adherence to secondary prophylaxis for RF is a challenging task. This study aimed to describe the rates of recurrent episodes of RF, quantify adherence to secondary prophylaxis, and examine the effects of medication adherence to the rates of RF in a cohort of Brazilian children and adolescents with RF.</p> <p>Methods</p> <p>This retrospective study took place in the Pediatric Rheumatology outpatient clinic at a tertiary care hospital (Instituto de Puericultura e Pediatria Martagão Gesteira) in Rio de Janeiro, Brazil, and included patients with a diagnosis of RF from 1985 to 2005.</p> <p>Results</p> <p>536 patients with RF comprised the study sample. Recurrent episodes of RF occurred in 88 of 536 patients (16.5%). Patients with a recurrent episode of RF were younger (p < 0.0001), more frequently males (p = 0.003), and less adherent (p < 0.0001) to secondary prophylaxis than patients without RF recurrence. Non-adherence to medication at any time during follow-up was detected in 35% of patients. Rates of non-adherence were higher in the group of patients that were lost to follow-up (42%) than in the group of patients still in follow-up (32%) (p = 0.027). Appointment frequency was inadequate in 10% of patients. Higher rates of inadequate appointment frequency were observed among patients who were eventually lost to follow-up (14.5%) than in patients who were successfully followed-up (8%) (p = 0.022). 180 patients (33.5%) were lost to follow up at some point in time.</p> <p>Conclusions</p> <p>We recommend implementation of a registry, and a system of active search of missing patients in every service responsible for the follow-up of RF patients. Measures to increase adherence to secondary prophylaxis need to be implemented formally, once non-adherence to secondary prophylaxis is the main cause of RF recurrence. Detection of irregularity in secondary prophylaxis or in appointments should be an alert about the possibility of loss of follow-up and closer observation should be instituted.</p

In Situ Dividing and Phagocytosing Retinal Microglia Express Nestin, Vimentin, and NG2 In Vivo

BACKGROUND: Following injury, microglia become activated with subsets expressing nestin as well as other neural markers. Moreover, cerebral microglia can give rise to neurons in vitro. In a previous study, we analysed the proliferation potential and nestin re-expression of retinal macroglial cells such as astrocytes and Müller cells after optic nerve (ON) lesion. However, we were unable to identify the majority of proliferative nestin(+) cells. Thus, the present study evaluates expression of nestin and other neural markers in quiescent and proliferating microglia in naïve retina and following ON transection in adult rats in vivo. METHODOLOGY/PRINCIPAL FINDINGS: For analysis of cell proliferation and cells fates, rats received BrdU injections. Microglia in retinal sections or isolated cells were characterized using immunofluorescence labeling with markers for microglia (e.g., Iba1, CD11b), cell proliferation, and neural cells (e.g., nestin, vimentin, NG2, GFAP, Doublecortin etc.). Cellular analyses were performed using confocal laser scanning microscopy. In the naïve adult rat retina, about 60% of resting ramified microglia expressed nestin. After ON transection, numbers of nestin(+) microglia peaked to a maximum at 7 days, primarily due to in situ cell proliferation of exclusively nestin(+) microglia. After 8 weeks, microglia numbers re-attained control levels, but 20% were still BrdU(+) and nestin(+), although no further local cell proliferation occurred. In addition, nestin(+) microglia co-expressed vimentin and NG2, but not GFAP or neuronal markers. Fourteen days after injury and following retrograde labeling of retinal ganglion cells (RGCs) with Fluorogold (FG), nestin(+)NG2(+) microglia were positive for the dye indicating an active involvement of a proliferating cell population in phagocytosing apoptotic retinal neurons. CONCLUSIONS/SIGNIFICANCE: The current study provides evidence that in adult rat retina, a specific resident population of microglia expresses proteins of immature neural cells that are involved in injury-induced cell proliferation and phagocytosis while transdifferentiation was not observed
