Assessment of fetal behavior using four-dimensional ultrasonography: current knowledge and perspectives

In the last decades, the development of real-time ultrasonography has allowed the direct view of the fetus in the uterus, as well as assessing its activity. The advent of threedimensional ultrasonography (3D) at the end of the 80s initiated a new era in diagnostic imaging for Obstetrics, dramatically increasing the possibility of studying the fetus. Recently, a new technique allowing the 3D image to be transformed into real-time was introduced: the four-dimensional (4D) ultrasonography. It allows the continuous monitoring of fetal face and other surface areas, such as the extremities. Some studies have already assessed this new methodology for fetal behavior observation during different stages of pregnancy, trying to understand better the relationship between fetal central nervous system maturation and the implications for its behavior. In this article, the authors review the current use of 4D ultrasonography in the assessment of fetal behavior, and discuss the possibilities of the technique to show the neurological development of the fetus, by means of watching movement and facial expressions. They also highlight the potential applicability of this new method in this new research area of fetal medicine.Durante as últimas décadas, o desenvolvimento da ultrassonografia em tempo real tem possibilitado a visibilização direta do feto no útero, bem como a avaliação de sua atividade. Com o advento da ultrassonografia tridimensional (3D) no final dos anos 1980, iniciou-se uma nova era no diagnóstico por imagem em Obstetrícia, ampliando-se sobremaneira a possibilidade do estudo fetal. Recentemente, uma técnica que permitiu que a imagem 3D fosse transformada em um modo em tempo real foi introduzida e tem sido chamada de ultrassonografia em quarta dimensão (4D), a qual permite o monitoramento contínuo da face fetal e de outras áreas da superfície do feto, como, por exemplo, suas extremidades. Alguns estudos já se ocuparam em avaliar esta nova metodologia na observação do comportamento fetal durante diferentes estágios da gestação, na tentativa de melhor entender as relações entre a maturação do sistema nervoso central do feto e suas implicações em seu padrão de comportamento. No presente artigo, os autores realizam uma revisão sobre o uso atual da ultrassonografia 4D na avaliação do comportamento fetal, discorrendo sobre as perspectivas da técnica em espelhar, por meio da observação de padrões de movimentos e expressões faciais, o desenvolvimento neurológico do feto, destacando as potenciais aplicabilidades dessa tecnologia como nova área de pesquisa em medicina fetal.Universidade Federal de São Paulo (UNIFESP) Departamento de ObstetríciaUniversidade Federal da ParaíbaUNIFESP, Depto. de ObstetríciaSciEL

“Era um Biquíni de Bolinha Amarelinha tão Pequenininho”: análise de um artefato cultural de moda e sua [re]significação a partir dos Estudos Culturais

O objetivo deste estudo foi desenvolver uma discussão sobre a influência de artefatos culturais em práticas socioculturais nos Estudos Organizacionais a partir das perspectivas de gênero e relações de poder tratados sob a égide dos Estudos Culturais. Foi delineado a partir da biografia e de aspectos históricos do biquíni através da lente teórico-metodológica do Circuito Cultural proposto por Du Gay et al. (1997). Foi construída uma representação gráfica de cunho teórico que discute as ideias abordadas neste estudo, indicando ser o biquíni uma vestimenta que integra o universo simbólico feminino em meio à evolução das convenções sociais em seu contexto de relações de gênero. Tal artefato do vestuário dispõe de uma cultura peculiar e se articula com práticas sociais próprias. O biquíni é discutido como um significante de status social a partir de práticas de resistências, contextos, indivíduos e ambientes, uma vez que ele representa um sujeito portador de uma cultura própria. As contribuições apontam para o entendimento de práticas sociais que estão associadas a um produto cultural, contemplando identidades culturais atreladas a sua projeção social como indumentária que reflete um protagonismo de gênero

14-weeks combined exercise epigenetically modulated 118 genes of menopausal women with prediabetes

Background: Pre-diabetes precedes Diabetes Mellitus (DM) disease and is a critical period for hyperglycemia treatment, especially for menopausal women, considering all metabolic alterations due to hormonal changes. Recently, the literature has demonstrated the role of physical exercise in epigenetic reprogramming to modulate the gene expression patterns of metabolic conditions, such as hyperglycemia, and prevent DM development. In the present study, we hypothesized that physical exercise training could modify the epigenetic patterns of women with poor glycemic control. Methods: 48 post-menopause women aged 60.3 ± 4.5 years were divided according to their fasting blood glucose levels into two groups: Prediabetes Group, PG (n=24), and Normal Glucose Group, NGG (n=24). All participants performed 14 weeks of physical exercise three times a week. The Infinium Methylation EPIC BeadChip measured the participants’ Different Methylated Regions (DMRs). Results: Before the intervention, the PG group had 12 DMRs compared to NGG. After the intervention, five DMRs remained different. Interestingly, when comparing the PG group before and after training, 118 DMRs were found. The enrichment analysis revealed that the genes were related to different biological functions such as energy metabolism, cell differentiation, and tumor suppression. Conclusion: Physical exercise is a relevant alternative in treating hyperglycemia and preventing DM in post-menopause women with poor glycemic control

Comparison between the six-minute walk test and the six-minute step test in post stroke patients

Abstract\ud \ud \ud \ud Background\ud The Stroke remains one of the major chronic diseases worldwide, and is considered a major cause of disability, which results not only in persistent neurological deficits, but also in the high physical deconditioning, nevertheless there are not many forms of assessing functional capacity in this population. We aimed to investigate the feasibility of the Six Minute Walk Teste and the Six-Minute Step Test (6MST) in post-stroke patients and compare the behavior of physiological variables during the 6MST and the Six-Minute Walk Test (6MWT), by correlating the functional performance obtained in both tests.\ud \ud \ud \ud Method\ud The 6MWT was carried out according to the American Thoracic Society (ATS) and the 6MST was performed in six minutes in order to compare it to the 6MWT in a 20 cm step. Was included post-stroke individuals able to walk without aid. All of them did the 6MWT and the 6MST.\ud \ud \ud \ud Results\ud 12 patients participated in the study. There was no statistical difference in the parameters analyzed when tests were compared. There was poor correlation between the functional performance in both tests.\ud \ud \ud \ud Conclusion\ud The 6MWT and the 6MST is feasible for post-stroke patients and physiological responses are equal during the performance of both tests. However, there was no correlation with respect to functional performance, which was assessed by the distance walked in the 6MWT and by the number of steps climbed in the 6MST.This study received financial support from Núcleo de Estudos, Pesquisas e Assessoria à Saúde da Faculdade de Medicina do ABC (NEPASFMABC).This study received financial support from Núcleo de Estudos, Pesquisas e Assessoria à Saúde da Faculdade de Medicina do ABC (NEPAS-FMABC)

Outcomes of allogeneic stem cell transplantation among patients with acute myeloid leukemia presenting active disease: Experience of a single European Comprehensive Cancer Center

Introduction: Allogeneic hematopoietic stem cell transplantation (ASCT) represents a potentially curative approach for patients with relapsed or refractory acute myeloid leukemia (AML). We report the outcome of relapsed/refractory AML patients treated with ASCT.Method: A retrospective cohort from 1994 to 2013 that included 61 patients with diagnosis of relapsed/refractory AML. Outcomes of interest were transplant-related mortality (TRM), incidence of acute and chronic graft-versus-host disease (GVHD), relapse incidence, progression-free survival (PFS) and overall survival (OS). Statistical significance was set at p<0.05.Results: The median age was 61 years (range 1 to 65). The cumulative incidence of 90 days, 1 year, and 3 years TRM were 60%, 26.7%, and 13.3%, respectively (p< 0.001). The incidence of relapse was 21.7% at 1 year, 13% at 3 years, and 8.7% at 5 years. Median OS was estimated to be 8 months (95CI 3.266-12.734) and median PFS, 3 months (95CI 1.835-4.165).Conclusion: In our cohort, TRM in first years after ASCT remains considerable, but ASCT in this setting seems to be a good choice for AML patients with active disease. However, novel approaches are needed to reduce TRM and relapse in this set of patients

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
