With the projected shortage of geriatricians over the next many years, it is essential for every internist and primary care physician to be equipped with the most current information and clinical skills for the treatment of older adults. This edition of Medical Clinics of North America brings the reader up to date on important issues in geriatrics including the following: treatment strategies for sarcopenia and frailty; congestive heart failure; revitalizing the aged brain; nutritional strategies for aging successfully; falls, osteoporosis and hip fractures; late-life Hypogonadism; hypertension in older persons; incontinence; delirium; weight loss; nursing homes and the physician; and diabetes and insulin resistance in older persons.

This two-volume set CCIS 173 and CCIS 174 constitutes the extended abstracts of the posters presented during the 14th International Conference on Human-Computer Interaction, HCII 2011, held in Orlando, FL, USA in July 2011, jointly with 12 other thematically similar conferences. A total of 4039 contributions was submitted to HCII 2011, of which 232 poster papers were carefully reviewed and selected for presentation as extended abstracts in the two volumes.

This issue of Clinics in Geriatric Medicine, Guest Edited by David Hunter, MD, will feature such article topics as: Epidemiology of Osteoarthritis; Age-Related Changes in the Musculoskeletal System and the Development of Osteoarthritis; The Contribution of Osteoarthritis to Disability; Etiology and Assessment of Disability in Older Adults; Quality of Osteoarthritis Care for Community-Dwelling Older Adults; Contextualizing Osteoarthritis Care and the Reasons for the Gap Between Evidence and Practice; Transforming Osteoarthritis Care in an Era of Health Care Reform; Strength Training in Older Adults: the Benefits for Osteoarthritis, Diet and Exercise in Older Obese Adults with Osteoarthritis; Device Use: Braces, Walking aids and orthotics; Pharmacologic Intervention for Osteoarthritis in Older Adults; Surgery in Older Adults with Osteoarthritis.

This four-volume set LNCS 6761-6764 constitutes the refereed proceedings of the 14th International Conference on Human-Computer Interaction, HCII 2011, held in Orlando, FL, USA in July 2011, jointly with 8 other thematically similar conferences. The revised papers presented were carefully reviewed and selected from numerous submissions. The papers accepted for presentation thoroughly cover the entire field of Human-Computer Interaction, addressing major advances in knowledge and effective use of computers in a variety of application areas. The papers of the fourth volume are organized in topical sections on HCI and learning, health and medicine applications, business and commerce, HCI in complex environments, design and usability case studies, children and HCI, and playing experience.

This issue covers a broad selection of topics critical to psychiatrist and any physician who treats older patients. Topics include: Epidemiology, clinical evaluation, and treatment of dementing disorders, late-life psychosis; suicide in late life; depression in primary care; structural neuroimaging of geriatric depression; gene-environment interactions in geriatric depression; treatment of geriatric depression; etiological Theories of Late-Life depression; geriatric bipolar disorder; psychotherapies in geriatric depression; home-based care of the elderly with mental disorders; functional neuroimaging in geriatric depression; models of treatment engagement of geriatric persons with mental disorders; and mental health service delivery to the elderly.

Societies around the world are concerned about dementia and the other forms of cognitive impairment that affect many older adults. We now know that brain changes typically begin years before people show symptoms, which suggests a window of opportunity to prevent or delay the onset of these conditions. Emerging evidence that the prevalence of dementia is declining in high-income countries offers hope that public health interventions will be effective in preventing or delaying cognitive impairments. Until recently, the research and clinical communities have focused primarily on understanding and treating these conditions after they have developed. Thus, the evidence base on how to prevent or delay these conditions has been limited at best, despite the many claims of success made in popular media and advertising. Today, however, a growing body of prevention research is emerging. Preventing Cognitive Decline and Dementia: A Way Forward assesses the current state of knowledge on interventions to prevent cognitive decline and dementia, and informs future research in this area. This report provides recommendations of appropriate content for inclusion in public health messages from the National Institute on Aging.
