Assessment of behavioral problems in dementia: The Revised Memory and Behavior Problems Checklist.

The Revised Memory and Behavior Problems Checklist (RMBPC), a 24-item, caregiver-report measure of observable behavioral problems in dementia patients, provides 1 total score and 3 subscale scores for S problems (memory-related, depression, and disruptive behaviors) and parallel scores for caregiver reaction. Data were obtained from 201 geriatric Ss and their caregivers. Factor analysis confirmed 3 1st-order factors, consistent with subscales just named, and 1 general factor of behavioral disturbance. Overall scale reliability was good, with alphas of .84 for S behavior and .90 for caregiver reaction. Subscale alphas ranged from .67 to .89. Validity was confirmed through comparison of RMBPC scores with well-established indexes of depression, cognitive impairment, and caregiver burden. The RMBPC is recommended as a reliable and valid tool for the clinical and empirical assessment of behavior problems in dementia Ss. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychophysiological Mediators of Caregiver Stress and Differential Cognitive Decline.

The authors examined relationships between chronic stress and cognitive decline and whether such relationships were mediated by psychophysiological factors. Ninety-six caregivers of spouses with Alzheimer's disease (AD) were compared with 95 similar noncaregiver spouses. All were free of diabetes. Although the groups started similarly, over 2 years caregivers declined by a small but significant amount (1 raw score point and 4 percentile points, each p     

KAΔMOE: A Clausal Language for CAD MOdeling Systems with Morphological Constraints

A declarative language (KAΔMOE) for CAD-CAM modeling is presented. The language is designed to protect topological models' constraints and guarantee their inheritance in complex entities built up from simpler ones. By itself, KAΔMOE behaves as an evolution of Prolog, which is integrated with primitives for modularization and for privatizing modeling structures so as to guarantee interfacing the language with relational or deductive Data Bases.     

Weight changes in caregivers of Alzheimer's care recipients: Psychobehavioral predictors.

Relationships of changes in body mass index (BMI) were examined with changes in psychobehavioral variables in spouse caregivers of individuals with Alzheimer's disease (n?=?81) and matched spouses of controls (n?=?86). Men caregivers had significantly greater BMI and obesity than men controls at both times. Over 15–18 months, women caregivers gained significantly more weight than did women controls. A trend for greater obesity occurred in women caregivers than in women controls at follow-up. Although weight gain was not related to psychobehavioral variables in controls, in men caregivers decreased perceived control and increased fat intake explained significant variance in weight gain. In women caregivers, increased anger control and increased calories explained weight gain. Such caregivers may be at risk for health problems.

EPA or DHA Supplementation Increases Triacylglycerol,but not Phospholipid,Levels in Isolated Rat Cardiomyocytes

It is well recognized that a high dietary intake of long-chain polyunsaturated fatty acids (LC-PUFA) has profound benefits on health and prevention of chronic diseases. In particular, in recent years there has been a dramatic surge of interest in the health effects of n-3 LC-PUFA derived from fish, eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids. Notwithstanding, the metabolic fate and the effects of these fatty acids once inside the cell has seldom been comprehensively investigated. Using cultured neonatal rat cardiomyocytes as model system we have investigated for the first time, by means of high-resolution magic-angle spinning nuclear magnetic resonance (HR-MAS NMR) spectroscopy in combination with gas chromatography (GC), the modification occurring in the cell lipid environment after EPA and DHA supplementation. The most important difference between control and n-3 LC-PUFA-supplemented cardiomyocytes highlighted by HR-MAS NMR spectroscopy is the increase of signals from mobile lipids, identified as triacylglycerols (TAG). The observed increase of mobile TAG is a metabolic response to n-3 LC-PUFA supplementation, which leads to an increased lipid storage. The sequestration of mobile lipids in lipid bodies provides a deposit of stored energy that can be accessed in a regulated fashion according to metabolic need. Interestingly, while n-3 LC-PUFA supplementation to neonatal rat cardiomyocytes causes a huge variation in the cell lipid environment, it does not induce detectable modifications in water-soluble metabolites, suggesting negligible interference with normal metabolic processes.     

Patients' expectations as predictors of orthognathic surgery outcomes.

109 patients (aged 14–43 yrs) rated their expectations of problems associated with surgery for dentofacial malrelation 6–22 mo before surgery and completed questionnaires 5 more times over the course of 3 yrs, from just before to 2 yrs after surgery. Presurgical expectations of problems were significant predictors of postsurgical reports of experiences, dissatisfaction, and mood disturbances up to 2 yrs after surgery. Contrary to the hypothesis that vigilant copers would have better outcomes than avoidant copers, results suggest that Ss who anticipated few problems with surgery (avoidant copers) reported better psychological outcomes than Ss who expected numerous problems (vigilant copers).

Sense of coherence moderates the relationship between life stress and natural killer cell activity in healthy older adults.

A sense of coherence (SOC) has been found to be a strong predictor of health outcomes and life satisfaction in older adults. This study investigated mood and immune effects of anticipated voluntary housing relocation in 30 healthy older adults and 28 age-matched controls and examined whether SOC would buffer effects of relocation on natural killer (NK) cell activity. Movers completed assessments and had blood drawn 1 month before relocation to congregate living facilities; controls were assessed concurrently. Compared with the control group, movers showed decreased positive mood and NK activity and elevated thought intrusion. Positive mood mediated the relationship of moving with NK activity, whereas SOC moderated this relationship. Low SOC movers had the poorest NK activity; that of high SOC movers was less compromised. These findings are consistent with possible salutogenic contributions of SOC and positive mood to immune function in older adults facing stressful life transitions.

Recovery after allogeneic marrow transplantation: prospective study of predictors of long-term physical and psychosocial functioning

No prospective data have documented the physical and psychosocial functioning of patients before and after BMT. In this study 67 allogeneic transplant patients completed standardized self-report measures pre-transplant. Survivors were re-assessed at 90 days (n = 34) and 1 year (n = 31) post-transplant. Telephone interviews established 4-year work history and performance status. Physical function was most impaired at 90 days post-transplant, with a return to pre-transplant levels of functioning by 1 year in most areas. By 2 years post-transplant, 68% of patients had returned to full-time work. Only 9% of 4-year survivors failed to return to full-time occupations. Mean levels of anxiety and depression did not change over the first year. Pre-transplant, 27% of patients reported depression and 41% reported elevated anxiety. Greater emotional distress at 1 year was predicted by pre-transplant family conflict, non-married status and development of less severe chronic GVHD. Impaired physical recovery at 1 year was predicted by more severe chronic GVHD, pre-transplant physical impairment and family conflict. The large majority of long-term survivors returned to full-time employment with normal physical and psychosocial functioning, although recovery took longer than 1 year for approximately 40%. Family relationships were important determinants of physical and emotional recovery.     

Are the salutogenic effects of social supports modified by income? A test of an "added value hypothesis".

Older adults (54 men, 113 women; M age?=?69.5 years) were examined to test the hypothesis that social supports would be more salutogenic (health promoting) for persons with lower incomes than for persons with higher incomes. Interactions of income and social supports (mean of 3 emotional scales of the Interpersonal Support Evaluation List) at study entry predicted changes 15–18 months later in a cardiovascular composite (linear combination of high-density lipoproteins-mean arterial pressure; p?p?$29,000/year). In contrast, interactions of the Tangible Support Scale with income did not occur. Persons with lower incomes may derive benefits from social supports that go beyond tangible assistance.

The role of teat skin contamination in the epidemiology of Staphylococcus aureus intramammary infections

Knowledge of the epidemiological pattern and the potential sources of infections is important to control Staphylococcus aureus in dairy herds. This paper reports the results of a study applying both pulse field gel electrophoresis (PGFE) and the assessment of a selected number of virulence genes to investigate the role of teat skin on Staph. aureus transmission among cows and on the contamination of milk. Overall 61 isolates were considered, 23 from teat skin, 33 from milk samples and 5 from curd samples. Teat swabs were taken in five herds, but in only three of them could Staph. aureus be isolated. Curd was sampled in three herds, but Staph. aureus could be isolated in only two herds. The distribution of isolates among herds confirmed the presence of herd-specific Staph. aureus strain in most of the herds. The same pattern was observed in teat skin samples, in quarter milk samples, and in the curd samples. Our findings are consistent with other studies showing the role of teat skin as a potential reservoir. Moreover, Staph. aureus was isolated from teat skin of confirmed Staph. aureus-negative cows that were segregated from infected ones. Our findings also suggest that some strains have higher chances to survive on teat skin and therefore to increase the risk for contamination of milk and milk products due to the persistence of intramammary infections.
