Patterns and predictive factors of loss of the independence trajectory among community-dwelling older adults.

Background: Independence is related to the aging process. Loss of independence is defined as the inability to make decisions and participate in activities of daily living (ADLs). Independence is related to physical, psychological, biological, and socioeconomic factors.

Protein intake, weight loss, dietary intervention, and worsening of quality of life in older patients during chemotherapy for cancer.

Decreased health-related quality of life (HRQoL) is common in patients with cancer. We investigated the effects of dietary intervention and baseline nutritional status on worsening of HRQoL in older patients during chemotherapy. In this randomized control trial assessing the effect on mortality of dietary advice to increase dietary intake during chemotherapy, this post hoc analysis included 155 patients with cancer at risk of malnutrition.

Prevalence of mild hyponatremia and its association with falls in older adults admitted to an emergency geriatric medicine unit (the MUPA unit).

Background: Hyponatremia is the most common electrolyte disorder in older adults and it can increase morbidity and mortality. Approximately one in three older adults fall each year; mild chronic hyponatremia can predispose this group to injurious falls and fractures and serum levels of sodium can also influence bone health. Little is known regarding the association between mild chronic hyponatremia and injurious fall prevalence in elderly patients admitted to the Emergency Department (ED).

Peripheral inflammatory processes are involved in Alzheimer's disease (AD). We aimed to determine whether plasma inflammatory mediator levels at diagnosis are associated with cognitive decline through a 2-year follow-up in AD patients. Patients (n = 109, mean age 79.

Effect of long-term omega 3 polyunsaturated fatty acid supplementation with or without multidomain intervention on cognitive function in elderly adults with memory complaints (MAPT): a randomised, placebo-controlled trial.

Background: No large trials have been done to investigate the efficacy of an intervention combining a specific compound and several lifestyle interventions compared with placebo for the prevention of cognitive decline. We tested the effect of omega 3 polyunsaturated fatty acid supplementation and a multidomain intervention (physical activity, cognitive training, and nutritional advice), alone or in combination, compared with placebo, on cognitive decline.

Methods: The Multidomain Alzheimer Preventive Trial was a 3-year, multicentre, randomised, placebo-controlled superiority trial with four parallel groups at 13 memory centres in France and Monaco.

Accuracy of Teledentistry for Diagnosing Dental Pathology Using Direct Examination as a Gold Standard: Results of the Tel-e-dent Study of Older Adults Living in Nursing Homes.

Importance: Dental neglect and high levels of unmet dental needs are becoming increasingly prevalent among elderly residents of long-term care facilities, although frail, elderly, and dependent populations are the most in need of professional dental care. Little is known about the validity of teledentistry for diagnosing dental pathology in nursing home residents.

Objectives: To evaluate the accuracy of teledentistry for diagnosing dental pathology, assessing the rehabilitation status of dental prostheses, and evaluating the chewing ability of older adults living in nursing homes (using direct examination as a gold standard).

Effectiveness of light paths coupled with personal emergency response systems in preventing functional decline among the elderly.

Introduction: The elderly population is at high risk of functional decline, which will induce significant costs due to long-term care. Dependency could be delayed by preventing one of its major determinants: falls. Light paths coupled with personal emergency response systems could prevent the functional decline through fall prevention.

Elevated Soluble Vascular Cell Adhesion Molecule-1 Is Associated With Cerebrovascular Resistance and Cognitive Function.

Background: Elevated plasma soluble vascular cell adhesion molecule-1 (sVCAM-1) is a presumed marker of endothelial dysfunction, both in the brain and systemic circulation. Impairments in memory and cognition have been associated with cardiovascular diseases, but little is known about their relationships to abnormal cerebral endothelial function.

Methods: We studied the cross-sectional association between sVCAM-1 and markers of cerebrovascular hemodynamics and cognitive function in 680 community-dwelling participants in the MOBILIZE Boston Study, aged 65 years and older.

[Medicines and frailty in older people. Towards a new nosological entity: A pharmacological frailty?].

Frailty is a complex geriatric syndrome linked to the overall decrease of physiological reserves. It could lead to disability and to an increase in mortality. Frailty could have an impact on the effect and on the use of medications.

Circulating vascular cell adhesion molecule-1 is associated with cerebral blood flow dysregulation, mobility impairment, and falls in older adults.

Soluble vascular cell adhesion molecule-1 (sVCAM-1) is associated with hypertension, vascular inflammation, and systemic endothelial dysfunction. We evaluated whether elevated plasma sVCAM-1 is associated with impaired cerebrovascular function and mobility impairments in elderly people. We studied the cross-sectional relationships between plasma sVCAM-1 level, gait speed, and cerebrovascular hemodynamics, and its longitudinal relationship with falls in 680 community-dwelling participants aged ≥65 years in the Maintenance of Balance, Independent Living, Intellect, and Zest in the Elderly (MOBILIZE) Boston Study.

Elevated circulating vascular cell Adhesion Molecule-1 (sVCAM-1) is associated with concurrent depressive symptoms and cerebral white matter Hyperintensities in older adults.

Background: Circulating vascular adhesion molecule-1 (sVCAM-1) is a presumed marker of endothelial activation and dysfunction, but little is known about its association with mood. We hypothesized that elevated plasma concentrations of sVCAM-1 may be a marker of depressive symptoms due to cerebral vascular disease.

Methods: We studied 680 community-dwelling participants in the MOBILIZE Boston Study, aged 65 years and older.

Reexamining the Effect of Antihypertensive Medications on Falls in Old Age.

Conflicting data on the relationship between antihypertensive medications and falls in elderly people may lead to inappropriate undertreatment of hypertension in an effort to prevent falls. We aimed to clarify the relationships between the chronic use of different classes of antihypertensive medications and different types of falls, to determine the effect of medication dose, and to assess whether the risk of falls is associated with differences in cerebral blood flow. We assessed demographics, clinical characteristics, and chronic antihypertensive medication use in 598 community-dwelling people with hypertension, aged 70 to 97 years, then followed them prospectively for self-reported falls using monthly calendar postcards and telephone interviews.

There is no correlation between peripheral inflammation and cognitive status at diagnosis in Alzheimer's disease.

Background: Besides the neurofibrillary tangles and amyloid plaques, an inflammatory process is involved at central and peripheral levels in Alzheimer's disease (AD). We aimed to determine whether peripheral inflammatory parameter levels, in plasma and in peripheral blood mononuclear cells (PBMCs), could be correlated with the cognitive status at the time of AD diagnosis.

Methods: Patients were included at diagnosis with MMSE score between 16 and 25 and were naive of symptomatic treatment for AD.

Frailty and Pain: Two Related Conditions.

Frailty is a multidimensional syndrome, involving functional, nutritional, biological and psychological aspects. This condition, defined as a decreased resistance to internal and external stressors, is predictive of adverse health outcomes, including disability and mortality. Importantly, the frailty syndrome is usually considered a reversible condition, thus amenable of specific preventive interventions.

Prevalence of peripheral artery disease in the elderly population in urban and rural areas of Central Africa: the EPIDEMCA study.

Objective: Data on peripheral artery disease in Africa are sparse and limited to urban areas. Given the urban/rural socio-economical gradient in these countries, we sought to determine the prevalence and risk factors of peripheral artery disease in urban and rural areas of two countries in Central Africa.

Methods: Individuals ≥65 years old living in two urban and rural areas of the Republic of Central Africa (ROC) and the Central African Republic (CAR) were invited.

MAPT STUDY: A MULTIDOMAIN APPROACH FOR PREVENTING ALZHEIMER'S DISEASE: DESIGN AND BASELINE DATA.

Objective: The Multidomain Alzheimer Preventive Trial (MAPT study) was designed to assess the efficacy of isolated supplementation with omega-3 fatty acid, an isolated multidomain intervention (consisting of nutritional counseling, physical exercise, cognitive stimulation) or a combination of the two interventions on the change of cognitive functions in frail subjects aged 70 years and older for a period of 3 years. Ancillary neuroimaging studies were additionally implemented to evaluate the impact of interventions on cerebral metabolism (FDG PET scans) and atrophy rate (MRIs), as well as brain amyloïd deposit (AV45 PET scans).

Design Patients: 1680 subjects (mean age: 75.

Optimization of the inclusion of Alzheimer's disease patients in international multicenter randomized trials: results of a national survey conducted in memory research centers in france.

Introduction: Since 2002, with the creation of Centers of Memory Resources and Research (CMRR), considerable progress has been made in France regarding the administrative and institutional framework within which Alzheimer's disease (AD) is managed. In this study, we explore three approaches that can help optimize the inclusion of patients in clinical trials related to AD. They are as follows: to assess communication concerning clinical trials on AD in French CMRR, to analyze the internal organization of these centers concerning the dynamics of inclusion, and to evaluate screening tools used.

Biomarkers have gained an increased importance in the past years in helping physicians to diagnose Alzheimer's disease (AD). This study was designed to identify a blood-based, transcriptomic signature that can differentiate AD patients from control subjects. The performance of the signature was then evaluated for robustness in an independent blinded sample population.

Efficacy of simple home-based technologies combined with a monitoring assistive center in decreasing falls in a frail elderly population (results of the Esoppe study).

Background: Increasing age often implies increasing frailty, and the oldest old are often described as a frail group with a high risk of developing functional impairments and multi-morbidities like falls at home, which often result in dependence in daily activities. This preliminary study evaluate the efficacy of light path coupled with tele-assistance service for preventing unintentional falls at home in a frail elderly population.

Methods: Study design is a longitudinal prospective cohort study from 1st July 2009 to 30 June 2010.
