Precision of a new tool to measure visceral adipose tissue (VAT) using dual-energy X-Ray absorptiometry (DXA).

OBJECTIVE: A new tool to quantify visceral adipose tissue (VAT) over the android region of a total body dual-energy x-ray absorptiometry (DXA) scan has recently been reported. The measurement, CoreScan, is currently available on Lunar iDXA densitometers. The purpose of the study was to determine the precision of the CoreScan VAT measurement, which is critical for understanding the utility of this measure in longitudinal trials. DESIGN AND METHODS: VAT precision was characterized in both an anthropomorphic imaging phantom (measured on 10 Lunar iDXA systems) and a clinical population consisting of obese women (n = 32). RESULTS: The intrascanner precision for the VAT phantom across 9 quantities of VAT mass (0-1,800 g) ranged from 28.4 to 38.0 g. The interscanner precision ranged from 24.7 to 38.4 g. There was no statistical dependence on the quantity of VAT for either the inter- or intrascanner precision result (p = 0.670). Combining inter- and intrascanner precision yielded a total phantom precision estimate of 47.6 g for VAT mass, which corresponds to a 4.8% coefficient of variance (CV) for a 1 kg VAT mass. Our clinical population, who completed replicate total body scans with repositioning between scans, showed a precision of 56.8 g on an average VAT mass of 1110.4 g. This corresponds to a 5.1% CV. Hence, the in vivo precision result was similar to the phantom precision result. CONCLUSIONS: The study suggests that CoreScan has a relatively low precision error in both phantoms and obese women and therefore may be a useful addition to clinical trials where interventions are targeted towards changes in visceral adiposity.

Standards Culturais: Brasil X Portugal

A Cultura pode ser definida de várias maneiras e cada autor tem uma visão própria do termo mas, genericamente, cultura pode ser entendida como o conjunto de características humanas que não são inatas e que se criam, preservam ou aprimoram com o convívio na sociedade, com a comunicação e cooperação entre indivíduos. Os membros de uma sociedade não estão conscientes dos seus valores culturais e somente percebem estes valores quando entram em “choque” com uma cultura diferente. Estas diferenças culturais podem criar confusões e mal-entendidos. As culturas Portuguesa e a Brasileira parecem ser bastante semelhantes: a mesma língua, as mesmas crenças, religião predominantemente católica e alimentos similares. Porém, apesar das semelhanças, e após entrevistas de carácter narrativo, observou-se nestas duas culturas características próprias e que muitas vezes foram necessárias adaptações para uma melhor integração na sociedade. Esta tese de mestrado é uma análise das diferenças culturais entre Portugal e Brasil e tem por objectivo encontrar standards culturais de ambos os países podendo ser um instrumento de ajuda para aqueles que vêm do Brasil para Portugal, e vice-versa, para trabalharem ou abrirem uma empresa. Os standards culturais encontrados, após análise comparativa, estão relacionados com a maneira de ver a vida, de ultrapassar os problemas e pressões do dia a dia, com colectivismo, hierarquia, simpatia, preocupação com o cliente, ansiedade face à incerteza e profissionalismo. Este trabalho termina com a identificação dos standards culturais e com dicas para aqueles que saem do seu país e recomeçam a sua vida noutro com cultura diferente

Neuropathological, clinical and molecular pathology in female fragile X premutation carriers with and without FXTAS.

Fragile X-associated tremor/ataxia syndrome (FXTAS) is an adult-onset neurodegenerative disorder associated with premutation alleles of the fragile X mental retardation 1 (FMR1) gene. Approximately 40% of older male premutation carriers, and a smaller proportion of females, are affected by FXTAS; due to the lower penetrance the characterization of the disorder in females is much less detailed. Core clinical features of FXTAS include intention tremor, cerebellar gait ataxia and frequently parkinsonism, autonomic dysfunction and cognitive deficits progressing to dementia in up to 50% of males. In this study, we report the clinical, molecular and neuropathological findings of eight female premutation carriers. Significantly, four of these women had dementia; of the four, three had FXTAS plus dementia. Post-mortem examination showed the presence of intranuclear inclusions in all eight cases, which included one asymptomatic premutation carrier who died from cancer. Among the four subjects with dementia, three had sufficient number of cortical amyloid plaques and neurofibrillary tangles to make Alzheimer's disease a highly likely cause of dementia and a fourth case had dementia with cortical Lewy bodies. Dementia appears to be more common than originally reported in females with FXTAS. Although further studies are required, our observation suggests that in a portion of FXTAS cases there is Alzheimer pathology and perhaps a synergistic effect on the progression of the disease may occur.
