Age And Premorbid Intelligence Suppress Complaint-Performance Congruency In Raw Score Measures Of Memory, Matthew Merema, Craig Speelman, Elizabeth Kaczmarek, Jonathan Foster

Research outputs 2012

Background: We aimed to examine the role of age and premorbid intelligence (IQ) in suppressing the relationship between subjective memory complaints (SMCs) and raw score memory performance. Methods: We used a community sample of older adults aged 66"90 years (N = 121) to test whether the inclusion of age and a premorbid IQ measure in multiple regression analyses increased semipartial correlations of raw score memory performance in predicting SMCs. Rank contrast correlations were also carried out to observe how age and premorbid IQ are related to complaint"performance congruency. Measures utilized in the study included the Memory Functioning Questionnaire (for SMCs), …

Predictors Of Rapid Cognitive Decline In Alzheimer's Disease: Results From The Australian Imaging, Biomarkers And Lifestyle (Aibl) Study Of Ageing, A Sona, P Zhang, D Ames, A I Bush, N T Lautenschlager, Ralph Martins, C L Masters, C C Rowe, C Szoeke, Kevin Taddei, Kathryn A Ellis

Research outputs 2012

Background: The AIBL study, which commenced in November 2006, is a two-center prospective study of a cohort of 1112 volunteers aged 60+. The cohort includes 211 patients meeting NINCDS-ADRDA criteria for Alzheimer's disease (AD) (180 probable and 31 possible). We aimed to identify factors associated with rapid cognitive decline over 18 months in this cohort of AD patients.

Methods: We defined rapid cognitive decline as a drop of 6 points or more on the Mini-Mental State Examination (MMSE) between baseline and 18-month follow-up. Analyses were also conducted with a threshold of 4, 5, 7 and 8 points, as well as …

Efficacy Of A Referral And Physical Activity Program For Survivors Of Prostate Cancer [Engage]: Rationale And Design For A Cluster Randomised Controlled Trial., Patricia M. Livingston, Jo Salmon, Kerry S. Courneya, Cadeyrn J. Gaskin, Melinda Craike, Mari Botti, Suzanne Broadbent, Bridie Kent

School of Nursing and Midwifery

BACKGROUND: Despite evidence that physical activity improves the health and well-being of prostate cancer survivors, many men do not engage in sufficient levels of activity. The primary aim of this study (ENGAGE) is to determine the efficacy of a referral and physical activity program among survivors of prostate cancer, in terms of increasing participation in physical activity. Secondary aims are to determine the effects of the physical activity program on psychological well-being, quality of life and objective physical functioning. The influence of individual and environmental mediators on participation in physical activity will also be determined. METHODS/DESIGN: This study is a …

Oxidative Stress Accumulates In Adipose Tissue During Aging And Inhibits Adipogenesis, Hannes M. Findeisen, Kevin J. Pearson, Florence Gizard, Yue Zhao, Hua Qing, Karrie L Jones, Dianne Cohn, Elizabeth B. Heywood, Rafael De Cabo, Dennis Bruemmer

Saha Cardiovascular Research Center Faculty Publications

Aging constitutes a major independent risk factor for the development of type 2 diabetes and is accompanied by insulin resistance and adipose tissue dysfunction. One of the most important factors implicitly linked to aging and age-related chronic diseases is the accumulation of oxidative stress. However, the effect of increased oxidative stress on adipose tissue biology remains elusive. In this study, we demonstrate that aging in mice results in a loss of fat mass and the accumulation of oxidative stress in adipose tissue. In vitro, increased oxidative stress through glutathione depletion inhibits preadipocyte differentiation. This inhibition of adipogenesis is at …

Aging Is Associated With Positive Responding To Neutral Information But Reduced Recovery From Negative Information, Carien M. Van Reekum, Stacey M. Schaefer, Regina C. Lapate, Catherine J. Norris, Lawrence L. Greischar, Richard J. Davidson

Dartmouth Scholarship

Studies on aging and emotion suggest an increase in reported positive affect, a processing bias of positive over negative information, as well as increasingly adaptive regulation in response to negative events with advancing age. These findings imply that older individuals evaluate information differently, resulting in lowered reactivity to, and/or faster recovery from, negative information, while maintaining more positive responding to positive information. We examined this hypothesis in an ongoing study on Midlife in the US (MIDUS II) where emotional reactivity and recovery were assessed in a large number of respondents (N = 159) from a wide age range (36–84 …

Hereditary 1,25-Dihydroxyvitamin D-Resistant Rickets With Alopecia Resulting From A Novel Missense Mutation In The Dna-Binding Domain Of The Vitamin D Receptor., Peter J. Malloy, Jining Wang, Tarak Srivastava, David Feldman

Manuscripts, Articles, Book Chapters and Other Papers

The rare genetic recessive disease, hereditary vitamin D resistant rickets (HVDRR), is caused by mutations in the vitamin D receptor (VDR) that result in resistance to the active hormone 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3) or calcitriol). In this study, we examined the VDR from a young boy with clinical features of HVDRR including severe rickets, hypocalcemia, hypophosphatemia and partial alopecia. The pattern of alopecia was very unusual with areas of total baldness, adjacent to normal hair and regions of scant hair. The child failed to improve on oral calcium and vitamin D therapy but his abnormal chemistries and his bone X-rays normalized …

Effects Of Caregiver Burden And Satisfaction On Affect Of Older End-Stage Renal Disease Patients And Their Spouses, Maureen Wilson-Genderson, Rachel A Pruchno, Francine P Cartwright

Rowan-Virtua School of Osteopathic Medicine Departmental Research

We examined the extent to which a 2-factor model of affect explains how the burdens and satisfactions experienced by caregivers influence their own well-being and that of the spouses for whom they provide care. Using data from 315 older patients with end-stage renal disease and their spouses, we extended tests of Lawton et al.'s (1991) 2-factor model both longitudinally and dyadically. Multilevel modeling analyses partially support the 2-factor model. Consistent with the model, mean caregiver burden has a stronger effect on both caregiver and patient negative affect than does mean caregiver satisfaction. Contrary to the model, mean caregiver satisfaction has …

Depressive Symptoms And Marital Satisfaction In The Context Of Chronic Disease: A Longitudinal Dyadic Analysis, Rachel Pruchno, Maureen Wilson-Genderson, Francine P Cartwright

Rowan-Virtua School of Osteopathic Medicine Departmental Research

These analyses examined the longitudinal relationships between depressive symptoms and marital satisfaction over a 2-year period as experienced by 315 patients with end-stage renal disease and their spouses. Using multilevel modeling, the authors examined both individual and cross-partner effects of depressive symptoms and marital satisfaction on patients and spouses, testing bidirectional causality. Results indicate that mean and time-varying depressive symptoms of both patients and spouses were associated with their own marital satisfaction. Although mean marital satisfaction was associated with own depressive symptoms for both patients and spouses, time-varying marital satisfaction did not affect depressive symptoms for either patients or spouses. …

Defective Dna Base Excision Repair In Brain From Individuals With Alzheimer's Disease And Amnestic Mild Cognitive Impairment, Lior Weissman, Dong-Gyu Jo, Martin M. Sørensen, Nadja C. De Souza-Pinto, William R. Markesbery, Mark P. Mattson, Vilhelm A. Bohr

Pathology and Laboratory Medicine Faculty Publications

Oxidative stress is thought to play a role in the pathogenesis of Alzheimer's disease (AD) and increased oxidative DNA damage has been observed in brain tissue from AD patients. Base excision repair (BER) is the primary DNA repair pathway for small base modifications such as alkylation, deamination and oxidation. In this study, we have investigated alterations in the BER capacity in brains of AD patients. We employed a set of functional assays to measure BER activities in brain tissue from short post-mortem interval autopsies of 10 sporadic AD patients and 10 age-matched controls. BER activities were also measured in brain …

Social Security And The African American Male (A Cash Transfer System), Eddie Davis

The Journal of Sociology & Social Welfare

All employed workers are required to contribute to the Social Security System; however,a disproportionatep ercentage of African American males never live long enough to collect any benefits from their contributions. On the other hand, the life-expectancy of white males is significantly longer than the life expectancy of African American males, and their collection of Social Security benefits tends to exceed their contributions to the system. The federal government keeps the Social Security system from becoming completely solvent by raiding it of any surplus funds it collects; thereby, preventing the Social Security Fund from developing interest income, and accumulating funds for …

Management Decisions Made By Caregiver Spouses Of Persons With Alzheimer's Disease., Mary A. Corcoran

Department of Occupational Therapy Faculty Papers

OBJECTIVES: As the incidence of Alzheimer's disease increases, so does the effect on families and friends who assume caregiving responsibilities. Despite the proliferation of caregiving studies reported in the literature, little is known of the day-to-day management styles and preferences of caregivers. To develop, implement, and test interventions designed to sustain caregivers in their role, more information is needed about the caregiving experience. Results of a descriptive study are presented as a first step in understanding the complex process of choosing, organizing, and implementing everyday caregiving tasks.

METHOD: Subjects of the study were 26 persons who provide care for a …

A Model To Promote Activity Competence In Elders., Ruth E. Levine, Laura N. Gitlin

Department of Occupational Therapy Faculty Papers

This paper describes an occupational therapy home-based intervention in which purposeful activities were used to promote adaptation and competence in older adults with chronic disabilities. Seven home care therapists visited 17 randomly selected, community-living elders who were chronically disabled and who volunteered to participate in the program. The number of visits ranged from 3 to 10 and occurred over a 3-month period according to clients' needs and wishes. Therapists enhanced their ability to enter the client's social and cultural system by using participant-observation techniques and collaboratively identified activities. Therapists documented each home visit with a structured fieldnote form. An analysis …

Gender Differences In Dementia Management Plans Of Spousal Caregivers: Implications For Occupational Therapy., Mary A. Corcoran

Department of Occupational Therapy Faculty Papers

Occupational therapists treating older people with Alzheimer disease know that they must also consider the others who are affected by the disease, the informal caregivers. Intervention is most effective when it enables both the impaired person and the primary caregiver to manage the secondary symptoms of dementia. Unfortunately, little is understood about how caregivers approach and carry out their tasks and about why male and female caregivers respond differently to their caregiving role in terms of depression, burden, stress, and substance abuse. This paper discusses the effects of gender on dementia management plans of spousal caregivers. Husbands and wives have …

Dementia Management: An Occupational Therapy Home-Based Intervention For Caregivers., Mary A. Corcoran, Laura N. Gitlin

Department of Occupational Therapy Faculty Papers

This paper describes an occupational therapy intervention designed for family caregivers of persons with dementia. The intervention, based on the framework of a competence-environmental press model and the principle of collaboration, was implemented during 5 home visits. Each visit was designed to build caregiving skills through collaboration in identifying problem areas, developing and implementing environmental strategies, and modifying management approaches. A case vignette illustrates the therapeutic process and outcomes. The theoretical rationale and structure of the intervention and innovative documentation for evaluation of the theoretic process are also presented.
