Optical coherence tomography aspects of Stargardt's disease: case report

The term fundus flavimaculatus (Stargardt disease) describes a group of inherited macular dystrophies characterized by multiple yellow to yellow-white flecks at the level of the retinal pigment epithelium. The authors describe findings in the patient with Stargardt's disease using optical coherence tomography (OCT), and suggest the examination to be valid as subsidiary method in the study of the characteristics of the retina in Stargardt's disease patients, but studies involving a series of patients should be able to show the most frequent findings in these cases.O termo fundus flavimaculatus (doença de Stargardt) descreve um grupo de distrofias maculares hereditárias caracterizadas por múltiplos flecks amarelados em nível do epitélio pigmentar da retina. Os autores descrevem os achados de tomografia de coerência óptica (OCT) em paciente portador de doença de Stargardt e sugerem que a OCT tem validade como exame subsidiário no estudo das características da retina de pacientes portadores da doença de Stargardt, embora estudos envolvendo maior número de pacientes sejam indicados para permitir traçar-se o perfil das alterações mais comuns nestes casos.Universidade Federal de São Paulo (UNIFESP) Departamento de Oftalmologia Setor de Ultra-som OcularUNIFESP Departamento de Oftalmologia Setor de Ultra-som OcularUNIFESP Departamento de Oftalmologia Setor de Eletrofisiologia OcularUNIFESP Departamento de Oftalmologia Setor de RetinaUNIFESP, Depto. de Oftalmologia Setor de Ultra-som OcularUNIFESP, Depto. de Oftalmologia Setor de Ultra-som OcularUNIFESP, Depto. de Oftalmologia Setor de Eletrofisiologia OcularUNIFESP, Depto. de Oftalmologia Setor de RetinaSciEL

Óbito por dengue 4 no Brasil em paciente com púrpura trombocitopênica idiopática

Dengue é atualmente um importante problema de saúde pública. O vírus da dengue (DENV) é classificado em quatro sorotipos distintos, DENV 1-4. Após 28 anos de ausência, o DENV-4 foi detectado novamente no Brasil em 2010 no Estado de Roraima, e um ano depois, o vírus foi identificado em outros estados do norte do país, Amazonas e Pará, seguido pelos estados do Rio de Janeiro e São Paulo. Em Minas Gerais, o primeiro caso confirmado de DENV-4 ocorreu no município de Frutal em 2011 e, desde então, o sorotipo foi isolado em um número crescente de pacientes. Apesar do DENV-2 estar associado a um maior risco de formas graves e morte, o DENV-4 também tem sido associado a casos graves e a risco aumentado de manifestações hemorrágicas. Neste relato, descrevemos o primeiro caso fatal confirmado por DENV-4 no Brasil. A paciente era uma menina de 11 anos do município de Montes Claros, no norte de Minas Gerais, Brasil. Apresentava púrpura trombocitopênica idiopática e evoluiu de forma fulminante durante a infecção por dengue, com óbito associado a complicações hemorrágicas. O diagnóstico foi confirmado pela detecção de anticorpos IgM específicos para dengue, por método imunoenzimático, e por semi-nested RT-PCR. Médicos e outros profissionais de saúde devem estar cientes que infecções por DENV-4 também podem resultar em formas graves da doença com complicações hemorrágicas e óbito, principalmente em pacientes com comorbidades.Dengue is currently a major public-health problem. Dengue virus (DENV) is classified into four distinct serotypes, DENV 1-4. After 28 years of absence, DENV-4 was again detected in Brazil in 2010 in Roraima State, and one year later, the virus was identified in the northern Brazilian states of Amazonas and Pará, followed by Rio de Janeiro and São Paulo. In Minas Gerais, the first confirmed case of DENV-4 occurred in the municipality of Frutal in 2011 and has now been isolated from a growing number of patients. Although DENV-2 is associated with the highest risk of severe forms of the disease and death due to the infection, DENV-4 has also been associated with severe forms of the disease and an increasing risk of hemorrhagic manifestations. Herein, the first fatal case of confirmed DENV-4 in Brazil is reported. The patient was an 11-year-old girl from the municipality of Montes Claros in northern Minas Gerais State, Brazil. She had idiopathic thrombocytopenic purpura as a comorbid condition and presented with a fulminant course of infection, leading to death due to hemorrhagic complications. Diagnosis was confirmed by detection of Dengue-specific antibodies using IgM capture enzyme-linked immunosorbent assay and semi-nested RT-PCR. Primary care physicians and other health-care providers should bear in mind that DENV-4 can also result in severe forms of the disease and lead to hemorrhagic complications and death, mainly when dengue infection is associated with coexisting conditions

Este artigo tem como principal objetivo apresentar alguns aspectos do sistema agrário no qual estão inseridos os municípios do Território de Identidade Baixo Sul da Bahia, analisando de forma mais específica aspectos socioambientais característicos da comunidade rural Buris, localizada no município de Ibirapitanga, traçando, assim, um panorama do seu sistema agrário. Para tanto, utilizando-se de aspectos da metodologia “análise-diagnóstico de sistemas agrários”, realiza-se leitura interpretativa do mosaico da paisagem dessa comunidade; traça-se breve panorama histórico de formação do sistema agrário local; e faz-se identificação das tipologias dos produtores. Para a apresentação de aspectos do sistema agrário no qual estão inseridos os municípios do Baixo Sul, construiu-se um mapa dos tipos de vegetação predominante nesse território de identidade, de forma a contribuir para o entendimento dos aspectos fisiográficos característicos em seus sistemas agrários; levantaram-se dados do PIB e sua composição; e levantaram-se ainda dados dos estabelecimentos agropecuários dos municípios de forma a apresentar características desses estabelecimentos. As informações foram levantadas em 2018. Os resultados apontaram que 10 dos 15 municípios têm a maior parcela da população vivendo em áreas rurais, o que torna importante a configuração dos sistemas agrários na manutenção dessas populações nessas áreas. Na comunidade rural Buris observou-se uma maioria de produtores tipicamente familiares. Percebeu-se na comunidade a necessidade de se adotarem políticas de desenvolvimento desse espaço considerando as especificidades de sua realidade fisiográfica e geoambienta

Floor and ceiling effects on the Montreal Cognitive Assessment in patients with Parkinson’s disease in Brazil

ABSTRACT Parkinson’s disease (PD) is a common neurodegenerative disease associated with cognitive impairment. The Montreal Cognitive Assessment (MoCA) has been used as a recommended global cognition scale for patients with PD, but there are some concerns about its application, partially due to the floor and ceiling effects. Objective: To explore the floor and ceiling effects on the MoCA in patients with PD in Brazil. Methods: Cross-sectional study with data from patients with PD from five Brazilian Movement Disorders Clinics, excluding individuals with a possible diagnosis of dementia. We analyzed the total score of the MoCA, as well as its seven cognitive domains. The floor and ceiling effects were evaluated for the total MoCA score and domains. Multivariate analyses were performed to detect factors associated with floor and ceiling effects. Results: We evaluated data from 366 patients with PD and approximately 19% of individuals had less than five years of education. For the total MoCA score, there was no floor or ceiling effect. There was a floor effect in the abstraction and delayed memory recall domains in 20% of our sample. The ceiling effect was demonstrated in all domains (80.8% more common in naming and 89% orientation), except delayed recall. Education was the main factor associated with the floor and ceiling effects, independent of region, sex, age at evaluation, and disease duration. Conclusion: The floor and ceiling effects are present in specific domains of the MoCA in Brazil, with a strong impact on education. Further adaptations of the MoCA structure for underrepresented populations may reduce these negative effects

GalNAc-T15 in gastric adenocarcinoma: Characterization according to tissue architecture and cellular location

Gastric cancer (GC) is the second most common cause of cancer-related deaths in the world. This study aims to investigate the differential tissue expression of ppGalNAc-T15 and to evaluate its possible association with clinical-pathological parameters and outcome of gastric adenocarcinoma patients. For these 70 patients were evaluated the expression by immunohistochemistry to ppGalNAc-T15. Our results showed that 33 (47.1%) patients were ppGalNAC-T15+ positive and 37 (52.9%) negative. Positive staining for ppGalNAc-T15 was significantly present in patients older than 60 years (P=0.0306) and submitted to total gastrectomy (P=0.0087). Also, some results remained at the limit of significance as surgical standing (P=0.0562) and histological grade (P=0.0549). Therefore, the ppGalNAc-T15 immunoreactivity can be useful to understand the prognosis of patients with gastric cancer

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino
