A New Cecal Slurry Preparation Protocol With Improved Long-Term Reproducibility For Animal Models Of Sepsis, Marlene E. Starr, Allison M. Steele, Mizuki Saito, Bill J. Hacker, B. Mark Evers, Hiroshi Saito

Surgery Faculty Publications

Sepsis, a life-threatening systemic inflammatory response syndrome induced by infection, is widely studied using laboratory animal models. While cecal-ligation and puncture (CLP) is considered the gold standard model for sepsis research, it may not be preferable for experiments comparing animals of different size or under different dietary regimens. By comparing cecum size, shape, and cecal content characteristics in mice under different experimental conditions (aging, diabetes, pancreatitis), we show that cecum variability could be problematic for some CLP experiments. The cecal slurry (CS) injection model, in which the cecal contents of a laboratory animal are injected intraperitoneally to other animals, is …

Interpersonal Communication In The Context Of Dementia: Examining Family Caregivers' Appraisals And Burden, Stacy Lynn Barnes

Dissertations (1934 -)

Purpose and Objectives: The purpose of this study was to explore dementia family caregivers' appraisals of communication behaviors and strategies, and their relationships to caregiver burden. Study objectives were to investigate: 1) the relationship between frequency of dementia-related communication behaviors and caregivers' appraisals of frustration; 2) the relationship between caregivers' use of communication strategies and appraisals of helpfulness; 3) the structural relationships between communication behavior appraisal, communication strategy appraisal, problem behaviors, and caregiver burden; and 4) caregiver education level as a moderating variable of the final structural model. Methods: A written, mailed questionnaire was developed to capture dementia family caregivers' …

The Impact Of Waist Circumference On Function And Physical Activity In Older Adults: Longitudinal Observational Data From The Osteoarthritis Initiative, John A. Batsis, Alicia J. Zbehlik, Laura K. Barre, Todd A. Mackenzie, Stephen J. Bartels

Dartmouth Scholarship

Background: We previously demonstrated that BMI is associated with functional decline and reduced quality of life. While BMI in older adults is fraught with challenges, waist circumference (WC) is a marker of visceral adiposity that can also predict mortality. However, its association with function and quality of life in older adults is not well understood and hence we sought to examine the impact of WC on six-year outcomes.

Methods: We identified adults aged ≥60 years from the longitudinal Osteoarthritis Initiative and stratified the cohort into quartiles based on WC. Our primary outcome measures of function at six year follow-up included: …

Fardo, Lijie Wan, Gregory A. Jicha, Gregory E. Cooper, Charles D. Smith, Allison M. Caban-Holt, Linda J. Van Eldik, Richard J. Kryscio

Sanders-Brown Center on Aging Faculty Publications

Aims: To evaluate the relationship between self-reported head injury and cognitive impairment, dementia, mortality, and Alzheimer's disease (AD)-type pathological changes. Methods: Clinical and neuropathological data from participants enrolled in a longitudinal study of aging and cognition (n = 649) were analyzed to assess the chronic effects of self-reported head injury. Results: The effect of self-reported head injury on the clinical state depended on the age at assessment: for a 1-year increase in age, the OR for the transition to clinical mild cognitive impairment (MCI) at the next visit for participants with a history of head injury was 1.21 and 1.34 …

Predictors Of Hospitalization Among Newly Admitted Skilled Nursing Facility Residents: Rethinking The Role Of Functional Decline, Sun J. Kim, Joo H. Lee, Shunichi Nakagawa, Elizabeth Bukowy, Ankoor Biswas, Boram Han, Yeilim Cho, Hyun Phil Shin, Ji Won Yoo

Journal of Patient-Centered Research and Reviews

Purpose: Hospital transfer from a skilled nursing facility (SNF) is costly, and many are potentially preventable. This study examines: 1) whether functional decline is a predictor of hospital transfer, and 2) the magnitude of relationships between predictors (functional impairment and chronic medical illness) and hospital transfer from SNFs.

Methods: We used Minimum Data Set (MDS) Version 2.0 in the state of Michigan between 2007 and 2009. In total, 196,662 new SNF admissions were observed. Multilevel generalized estimating equations and regression models were performed for each functional and clinical domain while adjusting for demographic variables and change in activities of daily …

Preventing Falls With Vitamin D, Franklin D. Shuler Md, Phd, Thomas Schlierf, Matthew Wingate

Orthopaedics

Falls are the number one cause for injury-related morbidity and mortality in West Virginia’s seniors. Multiple independent variables contribute to the risk of a fall: previous falls, alterations in balance and vision, impairments in gait and strength, and medications most highly correlate with the risk for a fall. Vitamin D supplementation is emerging as an easy, safe and well-tolerated fall reduction/prevention strategy due to the beneficial effects on the musculoskeletal system with improvements in strength, function and navigational abilities. From meta-analysis data, maximal fall reduction benefit in seniors is achieved when correcting vitamin D deficiency and when using adjunctive calcium …

Critical Role Of Tnf-Α In Cerebral Aneurysm Formation And Progression To Rupture., Robert M Starke, Nohra Chalouhi, Md, Pascal Jabbour Md, Stavropoula Tjoumakaris, L. Fernando Gonzalez, Robert H. Rosenwasswer Md, Kosuke Wada, Kenji Shimada, David M Hasan, Nigel H Greig, Gary K Owens, Aaron Dumont

Department of Neurosurgery Faculty Papers

BACKGROUND: Alterations in TNF-α expression have been associated with cerebral aneurysms, but a direct role in formation, progression, and rupture has not been established.

METHODS: Cerebral aneurysms were induced through hypertension and a single stereotactic injection of elastase into the basal cistern in mice. To test the role of TNF-α in aneurysm formation, aneurysms were induced in TNF-α knockout mice and mice pretreated with the synthesized TNF-α inhibitor 3,6'dithiothalidomide (DTH). To assess the role of TNF-α in aneurysm progression and rupture, DTH was started 6 days after aneurysm induction. TNF-α expression was assessed through real-time PCR and immunofluorescence staining.

The End Of Alzheimer's Disease - From Biochemical Pharmacology To Ecopsychosociology: A Personal Perspective, Peter J. Whitehouse

Faculty Scholarship

The future of the Alzheimer's disease (AD) field involves a more complete understanding not only the state of current scientific approaches, but also the linguistic and cultural context of preclinical and clinical research and policy activities. The challenges surrounding dementia are large and growing but are only part of broader social and health concerns. In this latter context, the current state of research in the AD area is reviewed together with necessary priorities in moving forward. Creating a more optimistic future will depend less on genetic and reductionist approaches and more on environmental and intergenerative approaches that will aid in …

The Relationship Between Fasting Serum Glucose And Cerebral Glucose Metabolism In Late-Life Depression And Normal Aging, C. M. Marano, C. I. Workman, C. H. Lyman, E. Kramer, C. R. Hermann, Y. L. Ma, V. Dhawan, T. Chaly, D. Eidelberg, G. S. Smith

Journal Articles

Evidence exists for late-life depression (LLD) as both a prodrome of and risk factor for Alzheimer's disease (AD). The underlying neurobiological mechanisms are poorly understood. Impaired peripheral glucose metabolism may explain the association between depression and AD given the connection between type 2 diabetes mellitus with both depression and AD. Positron emission tomography (PET) measures of cerebral glucose metabolism are sensitive to detecting changes in neural circuitry in LLD and AD. Fasting serum glucose (FSG) in non-diabetic young (YC; n=20) and elderly controls (EC; n=12) and LLD patients (n = 16) was correlated with PET scans of cerebral glucose metabolism …

Older Prisoners, Edward F. Ansello

Director's Editorials from Age in Action

The impact of an aging prison population is causing concern among different stakeholders, including prison officials, legislative bodies, clergy, and some gerontologists. Prison officials are scrambling to accommodate the numbers and needs of older inmates, but they are confounded by constrained budgets, inappropriate prison architecture, lack of gerontologically and geriatrically trained staff members, indifferent legislative bodies, and a general lack of awareness among the public of these problems. Our states need not only retrofitted and newly designed physical facilities but also staffs and providers with gerontological and geriatric training, from corrections personnel to health care providers to clergy and mental …

Breast cancer is predominantly a disease of older women, yet there is a knowledge gap due to the persisting misalignment between the age distribution of women with breast cancer and the age distribution of participants in clinical trials. The purpose of this report is to state the U13 conference breast cancer panel's recommendations regarding therapeutic clinical trials that will fill gaps in knowledge regarding the care of older patients with breast cancer. The U13 conference was a collaboration between the Cancer and Aging Research Group and the National Institute on Aging and the National Cancer Institute (NCI). Clinical trials should …

Psychotic Alzheimer's Disease Is Associated With Gender-Specific Tau Phosphorylation Abnormalities, Jeremy Koppel, C. Acker, P. Davies, O. L. Lopez, H. Jimenez, M. Azose, Blaine Greenwald, P. S. Murray, C. M. Kirkwood, J. Kofler, R. A. Sweet

Journal Articles

Converging evidence suggests that psychotic Alzheimer's disease (AD + P) is associated with an acceleration of frontal degeneration, with tau pathology playing a primary role. Previous histopathologic and biomarker studies have specifically implicated tau pathology in this condition. To precisely quantify tau abnormalities in the frontal cortex in AD + P, we used a sensitive biochemical assay of total tau and 4 epitopes of phospho-tau relevant in AD pathology in a postmortem sample of AD + P and AD - P. Samples of superior frontal gyrus from 26 AD subjects without psychosis and 45 AD + P subjects with psychosis …

Genome-Wide Mapping Of Ibd Segments In An Ashkenazi Pd Cohort Identifies Associated Haplotypes, V. Vacic, L. J. Ozelius, L. N. Clark, A. Bar-Shira, M. Gana-Weisz, T. Gurevich, A. Gusev, S. Guha, T. Lencz, A. Orr-Urtreger, +10 Additional Authors

Journal Articles

The recent series of large genome-wide association studies in European and Japanese cohorts established that Parkinson disease (PD) has a substantial genetic component. To further investigate the genetic landscape of PD, we performed a genome-wide scan in the largest to date Ashkenazi Jewish cohort of 1130 Parkinson patients and 2611 pooled controls. Motivated by the reduced disease allele heterogeneity and a high degree of identical-by-descent (IBD) haplotype sharing in this founder population, we conducted a haplotype association study based on mapping of shared IBD segments. We observed significant haplotype association signals at three previously implicated Parkinson loci: LRRK2 (OR = …

Self-Care Of Heart Failure In A House Call Program, Becky Bryant

Doctor of Nursing Practice Program Projects

The incidence and prevalence of persons living with heart failure (HF) is growing in the United States. Heart failure is the most common admission in hospitals among Medicare recipients aged 65 years or older. Self-care of heart failure (SCHF) has been reported to decrease HF hospital admission rates. Elderly patients who are homebound do not have access to typical HF education and follow-up care. The purpose of this evidence-based practice (EBP) project was to implement a SCHF program intervention by nurse practitioners (NPs) with homebound elderly HF patients receiving home visits in a house call program. There were 18 sample …

Differences In Mental Health Treatment Recommendations For Older And Younger Adults, Michelle M. Smith

Masters Theses

Failure to meet geriatric mental health needs is increasingly problematic. Research indicates that the problem is not simply a matter of insufficient numbers of mental health practitioners (MHPs), but also ageist attitudes and lack of knowledge about and training with older adults. The current study reviews the literature regarding knowledge about older people, education and training that mental health professionals receive, and the attitudes that are held by mental health professionals. The study also assessed for differences in treatment recommendations that MHP made for older versus younger clients, investigated whether MHP knowledge about the mental health of older adults, attitudes …

Let’S Play: Understanding The Role And Significance Of Digital Gaming In Old Age, Julie A. Skalsky Brown

Theses and Dissertations--Gerontology

Despite a marked increase in the use of digital games among older persons, there is insufficient research that provides insight into the gaming experiences of this population. A major demographic shift within the senior gaming market has ushered in a new perspective on the use of digital games as a tool for physical and cognitive health, and improved socialization. It is proposed that individual notions of play, which are developed over the life course, influence digital game play engagement and interaction preferences, and contribute to well-being. This study explored how self-perceptions of play over the course of the senior gamer’s …

The Use Of Physical Restraints Among Nursing Home Residents: Do Disparities Exist?, Shekinah Fashaw

HIM 1990-2015

Introduction: The purpose of this study is to examine how nursing home (NH) characteristics, specifically racial composition of nursing homes residents, influences the use of physical restraints. As the population ages and becomes more diverse, it is essential to mitigate/eliminate racial/ethnic disparities in quality care. Methods: This is cross-sectional study using a 2010 national data set from Brown University Center for Gerontology and Healthcare Research. This study employs Donabedian's Structure-Process-Outcome (SPO) conceptual framework. Statistical analysis includes univariate, bivariate, and a logistic regression model. It is hypothesized that nursing homes with higher proportions of black residents, more Medicaid residents, and for-profit …

Parkinson's Diagnosis From The Caregiver's Perspective, Helen Maree Bradley

Theses : Honours

Parkinson’s disease (Parkinson’s) is a progressive neurodegenerative disorder. The irreversible and accumulating disability experienced means that people with Parkinson’s progressively lose their autonomy, eventually requiring complete care. Consequently, Parkinson’s significantly impacts sufferers and the people who care for them. Informal care, predominantly provided by female spouses becomes exceptionally demanding over time, and caregivers experience significant morbidity. Stress manifests across all stages of the caregiving trajectory, with diagnosis reported as a particularly stressful period for caregivers; however, few attempts have been made to understand what makes it stressful. The current study explored female spousal caregivers’ subjective experience of the Parkinson’s diagnosis, …

Making Space For Dying: Portraits Of Living With Dying, Elise Lark

Antioch University Dissertations & Theses

In Making Space for Dying: Portraits of Living with Dying, I describe the everyday lived experience of dying and the care culture within freestanding, community-based, end-of-life residences (CBEOLR) utilizing portraiture and arts-based research. I craft four case studies into “portraits,” based on interviews, on-site visits, up-close observation, and field notes. In the person-centered portraits, I reveal the inner landscape of two terminally ill women, with data represented in poetry. In the place-centered portraits, I “map” the social topography of two CBEOLRs to illustrate how lives and care of the dying are emplaced, from the perspectives of community leaders, …
