Insults to the body civil: Mistreatment of elderly in two Plains Indian tribes

The mistreatment of elderly is subject to various social constructions. On two geographically distinct Plains Indian Reservations which we call Lone Mountain and Abundant Lands, the abuse or neglect of elderly is construed as a health problem which is a dysfunction of the community as a whole. Both physical abuse and neglect are more common on the Lone Mountain Reservation, occurring in association with other indicators of community disorganization such as unemployment and substance abuse. On the Abundant Lands Reservation physical abuse was categorically denied and what neglect existed appeared to be a function of role strain, geographic dispersal, climate and terrain. We attribute differences in the prevalence of mistreatment of elders to variations in economic opportunities for younger residents. Examining the historical and present contexts of intergenerational relationships on the reservations, we discuss the implications of this study for social exchange theory and policy applications.This research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America Applied

Heart health inequalities in Canada: modules, theory and planning

It is well known that prevalence and incidence rates of cardiovasculardisease (CVD) and CVD risk factors are not equally distributedamong socioeconomic groups. Known risk factors account for part,but not all of unequally distributed CVD rates. Socioeconomicconditions and psychosocial dynamics may explain another pareof the increased CVD rates. Theoretically, it may be possibleto lower CVD rates and CVD risk factor prevalence among lowersocioeconomic status (SES) groups by using a community development(socio-environment) strategy directed towards changes in socioenvrronmentalrisk conditions and psychosocial risk factors, rather than CVDrisk factors per Se. This article describes a protocol for sucha strategy based upon the planning work of Canadian health professionals,loosely organized under a project titled ‘Heart HealthInequalities in Canada’ This protocol incorporates baselinedata on CVD and CVD risk factor prevalence, but is premisedon actions negotiated between community organizations and healthauthorities, rather than defined unilaterally by health authorities.As such, program design activities and evaluation will differfrom a more general population-based risk factor reduction strategy.

Adaptive group sequential design for phase II clinical trials: A Bayesian decision theoretic approach

Bayesian decision theoretic approaches (BDTAs) have been widely studied in the literature as tools for designing and conducting phase II clinical trials. However, full Bayesian approaches that consider multiple endpoints are lacking. Since the monitoring of toxicity is a major goal of phase II trials, we propose an adaptive group sequential design using a BDTA, which characterizes efficacy and toxicity as correlated bivariate binary endpoints. We allow trade‐off between the two endpoints. Interim evaluations are conducted group sequentially, but the number of interim looks and the size of each group are chosen adaptively based on current observations. We utilize a loss function consisting of two components: the loss associated with accruing, treating, and monitoring patients, and the loss associated with making incorrect decisions. The performance of our Bayesian modeling, and the operating characteristics of decision rules under a wide range of loss function parameters are evaluated using seven scenarios in a simulation study. Our method is illustrated in the context of a single‐arm phase II trial of bevacizumab, gemcitabine, and oxaliplatin in patients with metastatic pancreatic adenocarcinoma.
