Despite attempts at active maintenance in the focus of attention, the fragile nature of the visual nonverbal memory trace may be revealed when the retention interval between target memoranda and probed recall on a trial is extended. In contrast, a passively maintained or unattended visual memory trace may be revealed as persisting proactive interference extending across quite extended intervals between trials in a recent probes task. The present study, comprising five experiments, used this task to explore the persistence of such a passive visual memory trace over time. Participants viewed some target visual items (for example, abstract colored patterns) followed by a variable retention interval and a probe item. The task was to report whether the probe matched one of the targets or not. A decaying active memory trace was indicated by poorer performance as the memory retention interval was extended on a trial. However, when the probe was a member of the target set from the preceding trial, task performance was poorer than a comparison novel probe, demonstrating proactive interference. Manipulations of the intertrial interval revealed that the temporal persistence of the passive memory trace of an old target was impressive, and proactive interference was largely resilient to a simple 'cued forgetting' manipulation. These data support the proposed two-process memory conception (active-passive memory) contrasting fragile active memory traces decaying over a few seconds with robust passive traces extending to tens of seconds.
BackgroundAlcoholic cirrhosis is an indication for 40% of liver transplantations (LT) in Europe. In most centers, 6 months of abstinence is required before listing. However, alcohol recidivism is quite high after LT, and approximately 20–25% of recipients with ALD resume harmful drinking, resulting in liver insufficiency, which casts doubt on the 6-months rule as a reliable marker of abstinence maintenance after LT.Material/MethodsWe analyzed data on patients who underwent orthotopic LT in Marie Curie Hospital, Szczecin, Poland, from 2000 to 2015 due to alcoholic or cryptogenic cirrhosis. Every ALD patient met the 6-month abstinence requirement. Alcohol recidivism has been studied based on a history of alcohol abuse taken from the patients or from their relatives, and in case of denial, on laboratory tests for alcohol abuse. Five patterns of recidivism were distinguished: death, constant heavy drinking, heavy drinking with abstinence attempts, occasional laps, and a single episode of alcohol intake. The analysis of survival was performed according to the Kaplan-Meier method. Patient survival rates in ALD recipients vs. non-ALD recipients were compared using the log-rank test.ResultsAlcohol recidivism was finally evaluated in 109 patients: 81 males and 28 females, with a median age of 53.3 years (range 30–66). Harmful drinking was discovered in 16 patients (14.7%), including seven deaths due to alcoholic hepatitis. Sporadic or episodic drinking was found in 29 patients (27%). In heavy drinkers, the abstinence period after transplantation was significantly shorter and patients were younger than the average (median age 43.8 years). Women break abstinence faster than men and are at greater risk of liver insufficiency. Five, 10 and 15-year survival in the ALD group was superior in comparison with non-ALD group, but differences did not reach statistical significance (p=0.066, p=0.063, p=0.075, respectively).ConclusionsThe prognostic value of a 6-month abstinence period before transplantation is rather low as it does not predict sobriety after transplantation. However, only a minority of such patients drink harmfully. Survival in ALD recipients tends to be better in comparison with survival in the other etiologies. Younger women dependent on alcohol shortly before LT are at greatest risk of recidivism.
Introduction While the Model of Human Occupation Screening Tool has undergone psychometric development and testing and is widely used in mental health practice, only a few small-scale studies to date have examined its use in clinical practice. Method A national survey was conducted with United Kingdom occupational therapists working in mental health settings to evaluate the use of the Model of Human Occupation Screening Tool. The survey included the modified version of the Usefulness, Satisfaction, and Ease of Use (USE) questionnaire and two open-ended questions. The latter were coded through inductive content analysis and all responses were analysed using Statistical Package for the Social Sciences software. Results n=105 questionnaires were analysed. The Model of Human Occupation Screening Tool was found to be a useful tool, with most therapists scoring it favourably on the usefulness (74.7%), ease of use (76.1%), ease of learning (81.2%) and satisfaction (80.6%) subscales. It was praised as a valuable outcome measure, guiding interventions and providing a comprehensive overview of assessed individuals. Time consumption, inaccessible terminology and lack of sensitivity to change were indicated as possible downfalls. Conclusion Therapists valued the Model of Human Occupation Screening Tool as an assessment tool, but more importance should be placed on training to overcome some of the limitations identified here. Also, its suitability to the setting in which it is used should be considered before implementation in practice.
