  Persistent, Consistent, Widespread, and Robust? Another Look at Recent Trends in Old-Age Disability

  摘要：

  Objective. The purpose of this study was to provide new evidence on disability trends among elderly persons from 1982 to 1996.Methods. The sample includes 125,949 participants aged 70 and older in the 1982-1996 National Health Interview Surveys. Logistic analysis was used to estimate the trend in disability prevalence after controlling for various sociodemographic factors.Results. We found that: (a) the prevalence of disability has declined, but the gains did not persist throughout the entire period or accelerate over time: (b) only routine care disability has declined. whereas more severe personal care disability shows no improvements; (c) estimates are robust to the exclusion of the nursing home population but may be sensitive to growth in the assisted living population: (d) estimates of decline in disability prevalence are fairly consistent across five national surveys: (e) gains have been concentrated among the most educated elderly persons: and (F) gains in education appear to be an important confounder of the improvements.Discussion. Evidence from several surveys using various measures indicate that disability has declined among elderly persons. Determining the causes of the improvements should be a high priority in future research efforts.

  摘要：

  邻苯二甲酰肼库是由取代的肼和邻苯二甲酰亚胺以几种不同的库格式在溶液中合成的，包括单一化合物，索引子库和完整的库。当在固相合成过程中进行时，这种组合的裂解和脱保护方案为生成取代的邻苯二甲酰肼的多样化文库提供了可能性。

• Implementation of a combinatorial cleavage and deprotection scheme. 1. Synthesis of phthalhydrazide libraries

  Phthalhydrazide libraries are synthesized in solution from substituted hydrazines and phthalimides in several different library formats including single compounds, indexed sub-libraries and a full library. When carried out during solid-phase synthesis, this combinatorial cleavage and deprotection scheme offers the possibility for generating a diverse library of substituted phthalhydrazides.
