Falls among older adults in the South of Brazil: prevalence and determinants
OBJETIVO: Avaliar a prevalĂȘncia e os fatores associados Ă ocorrĂȘncia de quedas em idosos. MĂTODOS: Estudo transversal com amostra representativa de 1.451 idosos residentes na zona urbana de Pelotas, RS, em 2014. Foi realizada anĂĄlise descritiva dos dados e apresentada a prevalĂȘncia de quedas no Ășltimo ano. A anĂĄlise de fatores demogrĂĄficos, socioeconĂŽmicos, comportamentais e de saĂșde associados ao desfecho foi realizada por meio de regressĂŁo de Poisson com ajuste para variĂąncia robusta conforme modelo hierĂĄrquico. As variĂĄveis foram ajustadas entre si dentro de cada nĂvel e para as de nĂvel superior. Aquelas com p †0,20 foram mantidas no modelo para controle de confusĂŁo e aquelas com p < 0,05 foram consideradas associadas ao desfecho. RESULTADOS: A prevalĂȘncia de quedas em idosos no Ășltimo ano foi de 28,1% (IC95% 25,9â30,5), e a maioria ocorreu na prĂłpria residĂȘncia do idoso. Entre os idosos que sofreram queda, 51,5% (IC95% 46,6â56,4) tiveram uma Ășnica queda e 12,1% (IC95% 8,9â15,3) tiveram fratura como consequĂȘncia, sendo a de membros inferiores a mais relatada. A prevalĂȘncia de quedas foi maior em mulheres, idosos com idade avançada, de menor renda e escolaridade, com incapacidade funcional para atividades instrumentais e portadores de enfermidades como diabetes, doença cardĂaca e artrite. CONCLUSĂES: A ocorrĂȘncia de quedas atingiu quase um terço dos idosos, e a prevalĂȘncia foi mais elevada em segmentos especĂficos da população em questĂŁo. Cerca de 12% dos idosos que caĂram, fraturaram algum osso. Os fatores associados Ă ocorrĂȘncia de quedas identificados neste estudo poderĂŁo nortear medidas que visem sua prevenção na população de idosos.OBJECTIVE: Evaluate the prevalence and the factors associated with the occurrence of falls among older adults. METHODS: A cross-sectional study with a representative sample of 1,451 elderly residents in the urban area of Pelotas, RS, in 2014. A descriptive analysis of the data was performed and the prevalence of falls in the last year was presented. The analysis of demographic, socioeconomic, behavioral and health factors associated with the outcome was performed using Poisson regression with adjustment for robust variance according to the hierarchical model. The variables were adjusted to each other within each level and for the higher level. Those with p †0.20 were maintained in the model for confounding control and those with p < 0.05 were considered to be associated with the outcome. RESULTS: The prevalence of falls among older adults in the last year was 28.1% (95%CI 25.9â30.5), and most occurred in the personâs own residence. Among the older adults who fell, 51.5% (95%CI 46.6â56.4) had a single fall and 12.1% (95%CI 8.9â15.3) had a fracture as a consequence, usually in the lower limbs. The prevalence of falls was higher in women, adults of advanced age, with lower income and schooling level, with functional incapacity for instrumental activities, and patients with diseases such as diabetes, heart disease, and arthritis. CONCLUSIONS: The occurrence of falls reached almost a third of the older adults, and the prevalence was higher in specific segments of the population in question. About 12% of the older adults who fell fractured some bone. The factors associated with the occurrence of falls identified in this study may guide measures aimed at prevention in the older adult population

Microspherical ReS2 as a High-Performance Hydrodesulfurization Catalyst
An unsupported microspherical ReS2
catalyst,
consisting in self-assembled nano-layers, was evaluated
in the hydrodesulfurization (HDS) of 3-methylthiophene
showing an excellent catalytic activity. The samples
were characterized by X-ray diffraction, scanning electron
microscopy, high resolution electron microscopy, energy
dispersive X-ray spectroscopy and X-ray photoelectron
spectroscopy. These techniques revealed that the rhenium
disulfide layers are confined to a 3D hierarchical structure
with different stacking, slab size and bending, according to the annealing temperature (400 or 800 °C). The presence of
a defect-rich structure in the microspheres, with short and
randomly-orientated ReS2
slabs, results in the exposure of
additional edge sites, which improve the catalytic performance
of this material. This microspherical ReS2
composite,
with good HDS performance, is a promising catalyst for
the desulfurization of fuel oils; the solvothermal reaction
conditions are also useful to tune and create exotic morphologies
for the design of new ReS2
catalysts
