BACKGROUND: Exercise interventions to prevent dementia and delay cognitive decline have gained considerable attention in recent years. Human and animal studies have demonstrated that regular physical activity targets brain function by increasing cognitive reserve. There is also evidence of structural changes caused by exercise in preventing or delaying the genesis of neurodegeneration. Although initial studies indicate enhanced cognitive performance in patients with mild cognitive impairment (MCI) following an exercise intervention, little is known about the effect of an extensive, controlled and regular exercise regimen on the neuropathology of patients with MCI...

The nutrient sensing protein, SIRT1 influences aging and nutritional interventions such as caloric restriction in animals, however, the role of SIRT1 in human aging remains unclear. Here, the role of SIRT1 single-nucleotide polymorphisms (SNPs) and serum-induced SIRT1 protein expression (a novel assay that detects circulating factors that influence SIRT1 expression in vitro) were studied in the Concord Health and Ageing in Men Project (CHAMP), a prospective cohort of community dwelling men aged 70 years and older...

Background: Frailty has been associated with increased risk of adverse-health related outcomes including cognitive impairment. However, little is know about the pathogenesis relating frailty to cognitive decline. Therefore, the main objective of this study was to investigate the association between vascular cerebral damage and frailty. Methods: Cross-sectional study involving 176 community-dwelling participants aged 67-86 years, participating in the AMImage Study, an ancillary neuro-imaging project of the AMI cohort, a French prospective cohort including older farmers living in rural areas...

BACKGROUND/OBJECTIVES: Malnutrition is an established risk factor for adverse clinical outcomes. Our aim was to assess nutritional status among geriatric trauma patients. SUBJECTS/METHODS: We enrolled 169 consecutive patients (⩾70 years) admitted to the Geriatric Traumatology Centre (University Hospital Zurich, Switzerland). On admission to acute care, nutritional status was assessed with the mini nutritional assessment (score<17=malnourished (M), ⩽23.5=at risk of malnutrition (ARM), >23...

BACKGROUND: To date there is no cure or an effective disease-modifying drug to treat dementia. Available acetylcholine-esterase inhibiting drugs or memantine only produce small benefits on cognitive and behavioural functioning and their clinical relevance remains controversial. Combined cognitive-aerobic interventions are an appealing alternative or add-on to current pharmacological treatments. The primary aim of this study is to investigate the efficacy of a combined cognitive-aerobic training and a single aerobic training compared to an active control group in older adults with mild dementia...

CONTEXT: As population grow older, chronic diseases are more prevalent. It leads to an increase of hospitalization for acute decompensation, sometimes iterative. Management of these patients is not always clear, and care provided is not always proportional to life expectancy. Making decisions in acute situations is not easy. OBJECTIVE: This review aims to list and describe mortality scores within a year following hospitalization of patients of 65 years or older...

BACKGROUND: International studies show that dementia is often recognized at later stages in general practice. Pure knowledge-sharing interventions could not change this in a sustainable manner. Concepts for changing attitudes of general practitioners (GPs) are required. OBJECTIVES: What barriers affect GPs' recognition of and diagnostic approach to dementia? What recommendations for a GP-specific diagnostic procedure can be derived from this? METHODS: Metasynthesis of qualitative studies with GPs on barriers to dementia recognition, explication of the "frailty" concept and the diagnostic approach described therein and the development of an approach in cases of suspected cognitive decline in a multiprofessional team...

Most people who work in aged care have a fair idea of what is meant by cognitive impairment or decline, and we have some moderately robust instruments for detecting it and measuring change over time. Frailty is much more difficult to define, but like hard core pornography (Stewart, 1964), many of us "know it when we see it."

BACKGROUND: Currently, patients older than 60 years of age represent 25% of the population and are at an increased risk during surgery. Therefore, reducing postoperative morbidity and mortality is a major concern in medical research and practice. Dependence on caregivers and cognitive impairment represent two major risk factors in the elderly, especially in frail patients after surgery under general anesthesia. In this context, continuous monitoring of the depth of anesthesia using a bispectral index (BIS) sensor may reduce the occurrence of impairments by gaining better control of the anesthetic depth...

BACKGROUND: Public awareness for dementia is rising and patients with concerns about forgetfulness are not uncommon in general practice. For the general practitioner (GP) subjectively perceived memory impairment (SMI) also offers a chance to broach the issue of cognitive function with the patient. This may support GPs' patient-centered care in terms of a broader frailty concept. OBJECTIVE: What is SMI (definition, operationalization, prevalence and burden)? Which conceptions and approaches do GPs have regarding SMI? METHODS: Narrative overview of recent SMI criteria and results, selective utilization of results from a systematic literature search on GP dementia care, non-systematic search regarding SMI in general practice, deduction of a study design from the overview and development according to international standards...

We present areas of uncertainty concerning intensive care unit-acquired weakness (ICUAW) and identify areas for future research. Age, pre-ICU functional and cognitive state, concurrent illness, frailty, and health trajectories impact outcomes and should be assessed to stratify patients. In the ICU, early assessment of limb and diaphragm muscle strength and function using nonvolitional tests may be useful, but comparison with established methods of global and specific muscle strength and physical function and determination of their reliability and normal values would be important to advance these techniques...

We examine recipients of publicly funded ongoing care in a single Ontario jurisdiction who reside in three different settings: long-stay home care patients in private homes and apartments, other patients in retirement homes and residents of long-term care homes, using interRAI assessment instruments. Among home care patients, those in retirement homes have higher proportions of dementia and moderate cognitive impairment, less supportive informal care systems as well as more personal care and nursing services above those provided by the public home care system, more frequent but shorter home support visits and lower than expected public home care expenditures...

Physical frailty and cognitive frailty are two important targets of secondary intervention in aging research to narrow the gap between life and health span. The objective of the present narrative review was to examine clinical and epidemiological studies investigating the recently proposed construct of cognitive frailty and its subtypes, with a focus on operational definitions, clinical criteria, and emerging biomarkers potentially useful for the screening of this novel entity. Both physical frailty and frailty indexes with a multidimensional nature were associated with late-life cognitive impairment/decline, incident dementia, Alzheimer's disease (AD), mild cognitive impairment, vascular dementia, non-AD dementias, and AD pathology proposing cognitive frailty as a clinical entity with cognitive impairment related to physical causes with a potential reversibility...

OBJECTIVE: In geriatric populations, frailty is associated with poor health outcomes, including mortality. Frailty has not been examined in lupus, although components of the phenotype seem relevant. METHODS: Women with lupus (n=152) participated in research visits in 2008-2009. Frailty was assessed by Fried's frailty phenotype criteria: low weight/unintentional weight loss, slow gait (4-m walk using sex and height criteria), weakness (grip strength using gender and body mass index criteria), exhaustion (2 specific questions) and inactivity (from physical activity questionnaire)...
