RESUMEN
BACKGROUND: While the U.S. National Institute on Aging has developed a strategy for recruitment of minority populations in dementia research, including increasing awareness and engagement, minority populations remain under-represented, and the evidence-base is limited. We tested a conceptually driven communication approach targeting barriers and facilitators to research participation vs. standard education. METHODS: In this 2-phase project, input from the minority advisory board of the Cleveland Alzheimer's Disease Research Center informed development of 2 brief health communication videos which differentially focused on research barriers and facilitators (POWER) versus an education control (Phase 1). In Phase 2, a randomized prospective survey compared POWER vs. an active comparator control on pre/post video change in dementia knowledge, cumulative barriers, and facilitators to dementia research, and change in research readiness measured by the Transtheoretical behavior change model. Changes in outcomes were evaluated using two group by two time points repeated measure analysis of variance (RMANOVA) controlling for age, gender, race, and education. RESULTS: The pre-video sample (n=242) had mean age of 57.6 (SD17.2) years, mostly female (n=181, 74.8%), 42.6% non-white. The analyzable sample who completed both pre and post assessments comprised n=102 in the POWER and n=105 in the control group. Non-white participants made up 41.1% of the analyzable POWER (n=51) and 44.1% (n= 52) of controls. Adjusted for age, gender, race and education, controls had a greater increase in dementia knowledge (p=0.004). There was a significant reduction in barriers for POWER (p=.044) vs. control. There were no differences in research facilitators and research readiness between POWER vs. control. Among African Americans (n=59, 28.5% of the analyzable sample) there was a trend for improved dementia knowledge (p=.059) favoring control and in research readiness (p=.051), favoring POWER. CONCLUSIONS: Targeting barriers and attitudes towards research could inform development of approaches with potential to improve dementia research participation across diverse communities.

This research evaluated the feasibility of actigraphy to measure sleep and physical activity in children (ages 2-8 years) with autism spectrum disorder (ASD). We also explored associations between sleep and physical activity. Validated screening measures established eligibility. Questionnaires, diaries, and 5 days and 5 nights of actigraphy monitoring were used to collect data. Of the 32 children enrolled, 27 (84.4%) completed actigraphy monitoring. Based on the median steps per day, children with high physical activity had lower total sleep time and more disruptive behaviors than children with low physical activity. Findings support the feasibility of using actigraphy to measure sleep and physical activity in children with ASD. Larger studies are needed to evaluate interactions of physical activity on sleep in this population.

Nearly 10 million women in the U.S. are caregivers for an elder with dementia, which often produces overwhelming stress and adversely affects their health. Resourcefulness training (RT) may promote the caregiver's optimal health and continue in their caregiving role. This pilot trial of 138 women dementia caregivers examined the effectiveness of RT on perceived stress, depressive cognitions, and negative emotions over time. Caregivers were first randomized to RT or no RT and then further randomized into random versus choice conditions followed by assignment to the journal or recorder methods, thus creating eight groups. We examined differences on perceived stress, depressive cognitions, and negative emotions between groups: 1) RT versus no-RT, 2) choice versus random condition; and 3) journaling versus recording. Significant time by group interactions were found on stress (F=4.36, p<.05), depressive cognitions (F=10.93, p<.001), and negative emotions (F=20.48, p<.001) in the RT versus no RT group. No differences were found between the random versus choice conditions or the journaling versus recording methods for practicing the RT skills. The results provide evidence for the effectiveness of RT for decreasing stress, depressive cognitions, and negative emotions in women caregivers of elders with dementia. The findings also suggest the need for further examination of the effects of allowing caregivers to choose a method for practicing RT in larger samples if caregivers of elders with dementia.
RESUMEN
SETTING: Public human immunodeficiency virus (HIV) clinic and tuberculosis (TB) clinics in Kampala, Uganda. OBJECTIVE: To examine TB-specific CD4 T-cell single and polyfunctional cytokine correlates of clinical diagnostic tests for latent tuberculous infection (LTBI) in HIV-1-infected subjects. DESIGN: Thirty antiretroviral therapy-naïve HIV-1-infected adults without active TB disease underwent clinical tuberculin skin test (TST), interferon-gamma release assay (IGRA), and in vitro flow cytometry analysis on cells stimulated with purified protein derivative (PPD) and TB antigens early secreted antigenic target 6 + culture filtrate protein 10 (EC) for frequencies of interleukin (IL) 2, IL-17, interferon-gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α) expressing cells. RESULTS: PPD-specific CD4 T-cell expression of TNF-α and IFN-γ was higher in the TST-positive than in the TST-negative group. EC-specific CD4 T-cell expression of TNF-α and IL-2 was higher in the TST+ group than in the TST- group. Expression of both PPD and EC-specific expression of IL-2, IFN-γ and TNF-α were greater in IGRA-positive than in IGRA-negative subjects. The TST+ group exhibited greater polyfunctionality than the TST- group. All cytokine combinations that contained TNF-α correlated strongly with TST size. CONCLUSION: While IL-2, IFN-γ and TNF-α correlate with clinical tests of LTBI, TNF-α is the dominant cytokine correlating with both TST size and magnitude of IGRA response.

This study examined health professionals' (HPs) experience, beliefs and attitudes towards brain death (BD) and two types of donation after circulatory death (DCD)--controlled and uncontrolled DCD. Five hundred and eighty-seven HPs likely to be involved in the process of organ procurement were interviewed in 14 hospitals with transplant programs in France, Spain and the US. Three potential donation scenarios--BD, uncontrolled DCD and controlled DCD--were presented to study subjects during individual face-to-face interviews. Our study has two main findings: (1) In the context of organ procurement, HPs believe that BD is a more reliable standard for determining death than circulatory death, and (2) While the vast majority of HPs consider it morally acceptable to retrieve organs from brain-dead donors, retrieving organs from DCD patients is much more controversial. We offer the following possible explanations. DCD introduces new conditions that deviate from standard medical practice, allow procurement of organs when donors' loss of circulatory function could be reversed, and raises questions about "death" as a unified concept. Our results suggest that, for many HPs, these concerns seem related in part to the fact that a rigorous brain examination is neither clinically performed nor legally required in DCD. Their discomfort could also come from a belief that irreversible loss of circulatory function has not been adequately demonstrated. If DCD protocols are to achieve their full potential for increasing organ supply, the sources of HPs' discomfort must be further identified and addressed.

In this study we examine the effects of aging on antigen presentation of B cells and monocytes. We compared the antigen presentation function of peripheral blood B cells from young and old subjects using a system that specifically measures the B cell receptor (BCR)-mediated MHC-II antigen presentation. Monocytes were studied as well. Overall the mean magnitude of antigen presentation of soluble antigen and peptide was not different in older and younger subjects for both B cells and monocytes. Older subjects, however, showed increased heterogeneity of BCR-mediated antigen presentation by their B cells. The magnitude and variability of peptide presentation, which do not require uptake and processing, were the same between groups. Presentation by monocytes had similar variability between the older and younger subjects. These data suggest that poor B cell antigen processing, which results in diminished presentation in some older individuals may contribute to poor vaccine responses.

Individuals with chronic HCV infection have impaired response to vaccine, though the etiology remains to be elucidated. Dendritic cells (DC) and monocytes (MN) provide antigen uptake, processing, presentation, and costimulatory functions necessary to achieve optimal immune responses. The integrity of antigen processing and presentation function within these antigen presenting cells (APC) in the setting of HCV infection has been unclear. We used a novel T cell hybridoma system that specifically measures MHC-II antigen processing and presentation function of human APC. Results demonstrate MHC-II antigen processing and presentation function is preserved in both myeloid DC (mDC) and MN in the peripheral blood of chronically HCV-infected individuals, and indicates that an alteration in this function does not likely underlie the defective HCV-infected host response to vaccination.

OBJECTIVE: The purpose of this report is to extend the current understanding of patient satisfaction by examining expectations of a sample of breast cancer patients and concordance with their medical oncologists about the content of consultations and the importance of consultation items. METHODS: Three hundred and ninety-five female early stage breast cancer patients of 56 oncologists participated. Patients and oncologists completed a matched questionnaire measuring (a) met expectations, (b) concordance over content and item importance, and (c) satisfaction. RESULTS: Overall patient satisfaction was extremely high (x=91/100%) although expectations were not met at the stated level desired. Patients and physicians disagreed over what was conveyed and received. Higher overall satisfaction was predicted by levels of met expectations (unstandardized beta=0.69, p=0.008, SE=0.26) and concordance over (a) content (unstandardized beta=1.09, p=0.002, SE=0.34) and (b) importance (unstandardized beta=-0.78, p=0.006, SE 0.28). CONCLUSION: Although patient expectations were not well met and physician-patient discord was high about the content of consultations and the importance of consultation items, patients reported high levels of satisfaction. Expectation fulfillment and levels of concordance predicted satisfaction.

Researchers in the aging field are paying increasing attention to the importance of perceived self-efficacy in understanding experiences and health-related outcomes of family caregivers. This paper details the strategy we used to measure family caregiver self-efficacy for managing dementia, and reports on observed associations between the resulting self-efficacy measures, caregiver depressive symptoms, and caregiver physical health symptoms. Family caregivers (n = 197) were interviewed after calling a local Alzheimer's Association chapter in the mid-western USA. Nine items inquiring about caregivers' certainty that they could carry out specific behaviors related to dementia care clustered into two distinct self-efficacy factors: symptom management self-efficacy (4 items) and community support service use self-efficacy (5 items). Internal consistency reliability for both factors was high (Cronbach's alpha = 0.77 and 0.78, respectively). Symptom management self-efficacy demonstrated a much stronger correlation with a published global caregiver competence measure than did service use self-efficacy (r = 0.49 and 0.27, respectively). In a multivariate regression model predicting caregiver depression symptoms, higher symptom management self-efficacy scores were associated with fewer depressive symptoms (beta = -0.17, p < 0.05). In a separate model, higher service use self-efficacy scores (beta = -0.20, p < 0.01) and higher symptom management self-efficacy scores (beta = -0.16, p < 0.05) were associated with fewer physical health symptoms. These new measures of dementia management self-efficacy hold promise for use in future studies.

OBJECTIVE: To compare elderly African American and white patients with osteoarthritis of the knee or hip with respect to their perceptions of the efficacy of traditional and complementary treatments and their self-care practices. METHODS: An observational, cross-sectional study design using structured questionnaires was employed. RESULTS: The sample consisted of 593 patients (44% African American and 56% white). The 2 groups were comparable with respect to age, disease severity or functional status, and comorbidities. African Americans were more likely than whites to report lower educational level and household income. African Americans were also more likely than whites to perceive various traditional and complementary care modalities as efficacious. However, they were less likely than whites to perceive joint replacement therapy as efficacious (odds ratio 0.52, 95% confidence interval 0.28-0.98). African American patients were more likely than white patients to rely on self-care measures for their arthritis. CONCLUSION: African American and white patients with osteoarthritis of the knee or hip differ with respect to their perceptions of traditional and complementary treatments for arthritis and their self-care practices.

Data from 252 female primary caregivers, their husbands, and children living in multigenerational households were used to create family typologies based on the extent of similarity among reports of elder behaviors. Analysis of variance indicates that families characterized by high agreement and those characterized by low agreement were significantly different from one another on a number of dimensions. When the relationship between caregiver-reported stressors and mental health was examined as a function of family typology, results indicate that for high agreement families there were significant correlations between the caregiver's report of the elder's behaviors and her burden; satisfaction with caregiving; relationships with her husband, child, and elder; and depression. Similar relationships characterize data reported by husbands and children in high agreement families. For families characterized by low agreement, the majority of these relationships were not significant.

Analyses examined whether information about the coping strategies used by family members adds to an understanding about the psychological well-being of individuals. Data from 140 women and their husbands and children who were living in multigenerational households that included a disabled older relative indicated that for the women and children, the best predictors of depression, positive affect, and mastery were their own coping strategies; the coping strategies used by other family members did not add significantly to the predictive equation. For husbands, however, depression was predicted by both their own coping strategies and the coping strategies of their wives. Husbands' positive affect was predicted only by the coping strategies of their wives and children, and their mastery was predicted by their own coping strategies and those of their wives and children.

A model in which the contributions made by older care receivers to their family members predicted personal control and ultimately psychological well-being of older people living in multigenerational households was proposed and tested. Data from 129 people over the age of 60 reveals that physical health predicts the extent to which elders contribute to the family, with those in poorer health giving less help to family members than those in better health. Elder contributions to the family increased the sense of control experienced by the older person. Although personal control increased the overall sense of psychological well-being experienced by the older care receivers, there was no direct relationship between the elder's contributions to the family and their psychological well-being.

Differences in the language spoken by residents and staff in long-term care create a variety of problems. The InterpreCare System represents an intervention for dealing with this issue. We describe the nature and purpose of this intervention, and provide detailed instructions on the construction of Language Boards. Examples are given from our experience at Menorah Park Center for the Aging in enabling English-speaking staff to use Russian phrases while delivering care. Beneficial effects produced by the intervention are discussed.

Data were collected from 838 women over age 50 who have either a child with a developmental disability or a child with schizophrenia. Lawton et al.'s (1991) parallel channel hypothesis, which suggests that positive and negative aspects of mental health have differential predictors, was tested. Results indicate that positive caregiving appraisals were predicted by quality of the mother-child relationship, while negative caregiving appraisals were predicted by the amount of help mother provided to her child, mother's health, child's behaviors, and positive appraisals. Positive well-being was predicted by mother's health, positive appraisals, and negative appraisals, while negative well-being was predicted by mother's health, child's behaviors, and negative appraisals. Hence, the data support the usefulness of the hypothesized model.

Structural equation analysis using data from 424 adult children with parents living in long-term care facilities indicated that the attachment experienced by adult children for their institutionalized parents was predicted from child's report of parent's mood and child's sense of guilt regarding his/her parent. Parent's mood was predicted by parent's health, and child's sense of guilt was predicted by the amount of help provided to the parent by the adult child. Results are interpreted in the context of theories of attachment.
