Rethinking functional limitation pathways.
Functional limitation has received considerable attention in gerontology and geriatrics. Much of this work has focused on single-wave transitions devoid of context rather than on the pattern of transitions over time that constitute trajectories. This Forum article suggests that it is time for a different way of looking at functional limitation pathways. It focuses on trajectories. Responses to ...
متن کاملFunctional limitation pathways and transitions in community-dwelling older persons.
The focus of this article is to determine the probability of making transitions through various ADL limitation levels, controlling for gender, age, and baseline ADL level, and using death as a competing outcome. We use the four waves of the Longitudinal Study of Aging and categorical data techniques to model the probability of these transitions. We find much heterogeneity among the transitions,...
متن کاملRethinking the Notion of Non-Functional Requirements
Requirements standards and textbooks typically classify requirements into functional requirements on the one hand and attributes or non-functional requirements on the other hand. In this classification, requirements given in terms of required operations and/or data are considered to be functional, while performance requirements and quality requirements (such as requirements about security, reli...
متن کاملBody composition and functional limitation in COPD
BACKGROUND Low body mass index has been associated with increased mortality in severe COPD. The impact of body composition earlier in the disease remains unclear. We studied the impact of body composition on the risk of functional limitation in COPD. METHODS We used bioelectrical impedance to estimate body composition in a cohort of 355 younger adults with COPD who had a broad spectrum of sev...
متن کاملRethinking glycolysis: on the biochemical logic of metabolic pathways.
Metabolic pathways may seem arbitrary and unnecessarily complex. In many cases, a chemist might devise a simpler route for the biochemical transformation, so why has nature chosen such complex solutions? In this review, we distill lessons from a century of metabolic research and introduce new observations suggesting that the intricate structure of metabolic pathways can be explained by a small ...
