Neuropathologic confirmation is required to validate the NINCDS-ADRDA Work Group criteria for the clinical diagnosis of Alzheimer's disease (AD). Neuropathologic inclusion and exclusion criteria for AD, however, are not uniform. The purpose of this investigation was to examine the confirmation rate for the Work Group criteria against differing neuropathologic criteria for AD. The sample consisted of 57 cases, 22 of which had received a clinical diagnosis of AD. Nine neuropathologic criteria for AD were applied in a blind fashion to each of the 57 cases. Our results indicated that, depending on the neuropathologic criteria applied, the clinicopathologic agreement ranged from 64% to 86%. These findings demonstrate the need for universally accepted neuropathologic and clinical criteria for AD.

Drawing on recent literature this article explores the development of research with family carers and people with dementia and identifies a number of themes that have emerged over time. It raises fundamental questions about the nature and purpose of research and the balance of power between researchers, family carers and people with dementia. Existing notions of expertise and knowledge are called into question and the article concludes with a call for a more empowering and inclusive model of research and practice based upon a relationship-centred approach to care.

This article describes the development of a new service for people with dementia and their carers in a large post-industrial city in the north of England, UK. The service arose in response to the perceived inadequacies of existing respite care provision and has proved very successful in meeting the needs of people with dementia and their family carers, and in providing high levels of job satisfaction for staff. The success of the initiative can be understood using the Senses Framework and relationship-centred care as an analytic lens to identify key attributes of the service. The article also discusses implications for the development of support services more generally.

Two separate dimensions called Fatalism and Social System Control (ssc) have been identified in recent research on I-E. The present studies were undertaken to examine whether subdimensions or other separate factors besides these two existed in I-E. It was found that contrary to previous interpretations Ss do not distinguish control of self from control of others within these two dimensions. Rather, the factor analytic data supported the interpretation that Fatalism and ssc differ only in terms of their "source" of control. The hypothesis that there Is a third dimension of I-E was supported. This dimension was identified as Self Control of one's impulses, desires, and emotions. Interpretation and implications for the application of these dimensions of I-E were discussed.

Changes in partners' sense of self-in-relationship, which a systemic-constructivist couple therapy (SCCT) induced, led to robust improvement in satisfaction in 2 studies and a follow-up study. In each study, 13 referred couples completed measures of satisfaction, mutuality, similarities, and other-in-self construal pre-post 12 hours of SCCT. The authors reliably coded transcripts of 1st and final sessions for each partner's we-ness, the identity that each partner establishes in relationship to the other. Having met the criteria for the rigorous study of change in single group process-outcome design, changes in we-ness accompanied large posttherapy dyadic increments on all variables in each study. Therapeutic gains appeared at follow-up and correlated with increased we-ness obtained at end of therapy 2 years earlier. The authors raise theoretical implications for all types of couple therapies and explain clinical techniques.

Concern exists that liver transplant center substance abuse policies may have an inappropriate and disproportionate impact on marijuana users. Our hypothesis is that patients with chronic liver disease who were marijuana users will have inferior survival. This is a retrospective (1999-2007) cohort study. The primary outcome measure is time-dependent, adjusted patient survival from the time of liver transplant evaluation. The primary exposure variable is a positive cannabinoid toxicology screen during the liver transplant evaluation period. Overall, 155 patients qualified as marijuana users while 1334 patients were marijuana non-users. Marijuana users were significantly (p < 0.05) younger (48.3 vs. 52.1), more likely to be male (78.1% vs. 63.0%), have hepatitis C (63.9% vs. 40.6%) and were less likely to receive a transplant (21.8% vs. 14.8%). Marijuana users were more likely to use tobacco, narcotics, benzodiazepines, amphetamines, cocaine or barbiturates (p < 0.05). Unadjusted survival rates were similar between cohorts. Upon multivariate analysis, MELD score, hepatitis C and transplantation were significantly associated with survival, while marijuana use was not (HR 1.09, 95% CI 0.78-1.54). We conclude that patients who did and did not use marijuana had similar survival rates. Current substance abuse policies do not seen to systematically expose marijuana users to additional risk of mortality.
