Mental Disorders of Aging: An Emerging Public Health Crisis?

Focuses on the emergence of public health crisis in the U.S. in connection with the projected increase in the number of older adults with mental disorders. Disorders which are commonly associated with older adults; Sources of mental health services for older adults; Factors that contribute to high levels of psychopathology; Impact of the economic costs of mental disorders on direct and indirect costs for healthcare; Recommendations for the expected crisis in geriatric mental health.

Mental Health and Aging at the 2005 White House Conference on Aging: Two Steps Forward, One Step Back

Success! At the 2005 White House Conference on Aging, three-quarters of the 1,200 national delegates voted to improve “recognition, assessment, and treatment of mental illness and depression among older Americans.” This resulted in mental health being ranked as #8 of the final 50 WHCoA policy resolutions resulting from the conference. Joining this resolution in the “top ten” were two resolutions intimately tied to hopes for addressing the mental health needs of older adults—at #6 “Support Geriatric Education and Training for Health Care Professionals, Paraprofessionals, Health Profession Students and Direct Care Workers,” and #9 “Attain Adequate Numbers of Healthcare Personnel in All Professions Who are Skilled, Culturally Competent, and Specialized in Geriatrics.”

Aging and mental health in the decade ahead: What psychologists need to know

Until relatively recently, most psychologists have had limited professional involvement with older adults. With the baby boomers starting to turn 65 years old in 2011, sheer numbers of older adults will continue to increase. About 1 in 5 older adults has a mental disorder, such as dementia. Their needs for mental and behavioral health services are not now adequately met, and the decade ahead will require an approximate doubling of the current level of psychologists' time with older adults. Public policy in the coming decade will face tensions between cost containment and facilitation of integrated models of care. Most older adults who access mental health services do so in primary care settings, where interdisciplinary, collaborative models of care have been found to be quite effective. To meet the needs of the aging population, psychologists need to increase awareness of competencies for geropsychology practice and knowledge regarding dementia diagnosis, screening, and services. Opportunities for psychological practice are anticipated to grow in primary care, dementia and family caregiving services, decision-making-capacity evaluation, and end-of-life care. Aging is an aspect of diversity that can be integrated into psychology education across levels of training. Policy advocacy for geropsychology clinical services, education, and research remains critical. Psychologists have much to offer an aging society

Apparent diffusion coefficient in the aging mouse brain: a magnetic resonance imaging study

Novel magnetic resonance imaging sequences have and still continue to play an increasing role in neuroimaging and neuroscience. Among these techniques, diffusion-weighted imaging (DWI) has revolutionized the diagnosis and management of diseases such as stroke, neoplastic disease and inflammation. However, the effects of aging on diffusion are yet to be determined. To establish reference values for future experimental mouse studies we tested the hypothesis that absolute apparent diffusion coefficients (ADC) of the normal brain change with age. A total of 41 healthy mice were examined by T2-weighted imaging and DWI. For each animal ADC frequency histograms (i) of the whole brain were calculated on a voxel-by-voxel basis and region-of-interest (ROI) measurements (ii) performed and related to the animals' age. The mean entire brain ADC of mice <3 months was 0.715(+/-0.016) x 10(-3) mm2/s, no significant difference to mice aged 4 to 5 months (0.736(+/-0.040) x 10(-3) mm2/s) or animals older than 9 months 0.736(+/-0.020) x 10(-3) mm2/s. Mean whole brain ADCs showed a trend towards lower values with aging but both methods (i + ii) did not reveal a significant correlation with age. ROI measurements in predefined areas: 0.723(+/-0.057) x 10(-3) mm2/s in the parietal lobe, 0.659(+/-0.037) x 10(-3) mm2/s in the striatum and 0.679(+/-0.056) x 10(-3) mm2/s in the temporal lobe. With advancing age, we observed minimal diffusion changes in the whole mouse brain as well as in three ROIs by determination of ADCs. According to our data ADCs remain nearly constant during the aging process of the brain with a small but statistically non-significant trend towards a decreased diffusion in older animals.

Effects of an aging vascular model on healthy and diseased hearts

The vitamin D(3) and nicotine (VDN) model is a model of isolated systolic hypertension (ISH) due to arterial calcification raising arterial stiffness and vascular impedance similar to an aged and stiffened arterial tree. We therefore analyzed the impact of this aging model on normal and diseased hearts with myocardial infarction (MI). Wistar rats were treated with VDN (n = 9), subjected to MI by coronary ligation (n = 10), or subjected to a combination of both MI and VDN treatment (VDN/MI, n = 14). A sham-treated group served as control (Ctrl, n = 10). Transthoracic echocardiography was performed every 2 wk, whereas invasive indexes were obtained at week 8 before death. Calcium, collagen, and protein contents were measured in the heart and the aorta. Systolic blood pressure, pulse pressure, thoracic aortic calcium, and end-systolic elastance as an index of myocardial contractility were highest in the aging model group compared with MI and Ctrl groups (P(VDN) < 0.05, 2-way ANOVA). Left ventricular wall stress and brain natriuretic peptide (P(VDNxMI) = not significant) were highest, while ejection fraction, stroke volume, and cardiac output were lowest in the combined group versus all other groups (P(VDNxMI) < 0.05). The combination of ISH due to this aging model and MI demonstrates significant alterations in cardiac function. This model mimics several clinical phenomena of cardiovascular aging and may thus serve to further study novel therapies.

Experimental study of physical aging effects on properties of EPON 862-DETDA

Epoxies find variety of applications and during these applications they get exposed to different conditions like elevated temperatures, hydrothermal, chemical, etc. It has been observed that properties of epoxies do get affected substantially if exposed to these conditions for extended period of time and because of the variety of applications, researchers found it necessary to study their effects on the thermal, mechanical, physical and chemical properties. However in this report the focus is on studying effects of physical aging on mechanical properties of EPON 862 with DETDA as its curing agent, where physical aging is aging is the condition which occurs due to exposure to elevated temperatures. A fair amount of computational work has been performed on EPON 862- DETDA to study the effects of physical aging, however very little known work has been done experimentally to study these effects. Young’s modulus, hardness, failure strength, strain to failure, density and glass transition are the properties which have been obtained using various experimental methods - tensile testing, nanoindentation and differential scanning calorimetry. Experimental work on other epoxies have shown no increase or very slight increase in the Young’s modulus and hardness with increased aging time, also decrease in failure strength and strain to failure and through this work on EPON 862- DETDA we can observe similar trends.

Creative Commons International The International License Porting Project

When Creative Commons (CC) was founded in 2001, the core Creative Commons licenses were drafted according to United States Copyright Law. Since their first introduction in December 2002, Creative Commons licenses have been enthusiastically adopted by many creators, authors, and other content producers – not only in the United States, but in many other jurisdictions as well. Global interest in the CC licenses prompted a discussion about the need for national versions of the CC licenses. To best address this need, the international license porting project (“Creative Commons International” – formerly known as “International Commons”) was launched in 2003. Creative Commons International works to port the core Creative Commons licenses to different copyright legislations around the world. The porting process includes both linguistically translating the licenses and legally adapting the licenses to a particular jurisdiction such that they are comprehensible in the local jurisdiction and legally enforceable but concurrently retain the same key elements. Since its inception, Creative Commons International has found many supporters all over the world. With Finland, Brazil, and Japan as the first completed jurisdiction projects, experts around the globe have followed their lead and joined the international collaboration with Creative Commons to adapt the licenses to their local copyright. This article aims to present an overview of the international porting process, explain and clarify the international license architecture, its legal and promotional aspects, as well as its most recent challenges.

Biochemical typing of pathological prion protein in aging cattle with BSE

BACKGROUND: The broad enforcement of active surveillance for bovine spongiform encephalopathy (BSE) in 2000 led to the discovery of previously unnoticed, atypical BSE phenotypes in aged cattle that differed from classical BSE (C-type) in biochemical properties of the pathological prion protein. Depending on the molecular mass and the degree of glycosylation of its proteinase K resistant core fragment (PrPres), mainly determined in samples derived from the medulla oblongata, these atypical cases are currently classified into low (L)-type or high (H)-type BSE. In the present study we address the question to what extent such atypical BSE cases are part of the BSE epidemic in Switzerland. RESULTS: To this end we analyzed the biochemical PrPres type by Western blot in a total of 33 BSE cases in cattle with a minimum age of eight years, targeting up to ten different brain regions. Our work confirmed H-type BSE in a zebu but classified all other cases as C-type BSE; indicating a very low incidence of H- and L-type BSE in Switzerland. It was documented for the first time that the biochemical PrPres type was consistent across different brain regions of aging animals with C-type and H-type BSE, i.e. independent of the neuroanatomical structure investigated. CONCLUSION: Taken together this study provides further characteristics of the BSE epidemic in Switzerland and generates new baseline data for the definition of C- and H-type BSE phenotypes, thereby underpinning the notion that they indeed represent distinct prion disease entities.
