Sensitivity, Specificity, Positive and Negative Predictive Values of a Postal Mail Self-Screening Tool for Frailty in French Older Adults.

BACKGROUND: Frailty has emerged as one of the major risk factors of loss of autonomy and it can be reverted through early and appropriate interventions. A wide range of available frailty screening tools are administered, mainly in clinical settings. However, few frailty instruments are self-administered. OBJECTIVES: The aim of this study was to determine the diagnostic test accuracy of a modified self-administered questionnaire derived from the Study of Osteoporotic Fractures (SOF) index against the Fried frailty phenotype in identifying frailty. DESIGN: Observational, multicenter, diagnostic test accuracy study. PARTICIPANTS: Participants aged 70 and over, living at home or in community-dwelling (n=5134) in two centers in France were contacted. MEASUREMENTS: Participants were mailed self-administered questionnaires derived from the SOF index. Responders who accepted the home evaluation were assessed by trained nurses, blinded to results of the questionnaire, using the Fried frailty phenotype as the reference method. RESULTS: The questionnaire was sent to 5134 participants, of which 1878 (36.6%) met inclusion criteria and returned the questionnaire. Fried frailty assessments were obtained in 691 (35.4%) participants. A total of 639 subjects had a complete evaluation on both the self-administered questionnaire and the Fried phenotype. Mean age was 78.9 (standard deviation [SD]: 5.95) years and 359 (56.2%) participants were women. According to the questionnaire, 159 (24.9%) subjects were considered frail, 172 (26.9%) pre-frail, and 308 (48.2) robust. With the home evaluation, Fried frailty phenotype results were respectively, 114 (17.8%), 295 (46.2%) and 230 (36%). The self-administered questionnaire presented a sensitivity of 66.6% (95% CI: 57.2-75.2) and a specificity of 84.2% (95% CI: 80.8-87.2). CONCLUSIONS: A self-administered questionnaire can be used in elders and represents an opportunity for empowering them in the management of their health in the context of frailty.

Relationship between achieved personalized glycaemic targets and monitoring of clinical events in elderly diabetic patients.

AIM: Recent guidelines for the management of type 2 diabetes (T2DM) in the elderly recommend adjusting the therapeutic target (HbA1c) according to the patient's health. Our study aimed to explore the association between achieving the recommended personalized HbA1c target and the occurrence of major clinical events under real-life conditions. METHODS: The T2DM S.AGES cohort was a prospective multicentre study into which 213 general practitioners recruited 983 non-institutionalized T2DM patients aged>65 years. The recommended personalized HbA1c targets were<7%, <8% and <9% for healthy, ill and very ill patients, respectively. Major clinical events (death from any cause, major vascular events and/or hospitalization) were recorded during the 3-year follow-up. Mixed-effects logistic regression models were used for the analyses. RESULTS: Of the 747 patients analyzed at baseline, 551 (76.8%) were at their recommended personalized HbA1c target. During follow-up, 391 patients (52.3%) experienced a major clinical event. Of the patients who did not achieve their personalized HbA1c target (compared with those who did), the risk (OR) of a major clinical event was 0.95 (95% CI: 0.69-1.31; P=0.76). The risk of death, major vascular event and hospitalization were 0.88 (95% CI: 0.40-1.94; P=0.75), 1.14 (95% CI: 0.7-1.83; P=0.59) and 0.84 (95% CI: 0.60-1.18; P=0.32), respectively. CONCLUSION: Over a 3-year follow-up period, our results showed no difference in risk of a major clinical event among patients, regardless of whether or not they achieved their personalized recommended HbA1c target. These results need to be confirmed before implementing a more permissive strategy for treating T2DM in elderly patients.

Therapeutic management in ambulatory elderly patients with atrial fibrillation: the S.AGES cohort.

UNLABELLED: Few epidemiologic studies have specifically focused on very old community dwelling population with atrial fibrillation (AF). The objectives of the AF-S.AGES cohort were to describe real-life therapeutic management of non-institutionalized elderly patients with AF according to age groups, i.e., 65-79 and ≥ 80 and to determine the main factors associated with anticoagulant treatment in both groups. METHODS: Observational study (N=1072) aged ≥ 65 years old, recruited by general practitioners. Characteristics of the sample were first evaluated in the overall sample and according to age (< 80 or ≥ 80 years) and to use of anticoagulant treatment at inclusion. Logistic models were used to analyze the determinants of anticoagulant prescription among age groups. RESULTS: Mean age was 78.0 (SD=6.5) years and 42% were ≥ 80 years. Nineteen percent had paroxysmal AF, 15% persistent, 56% permanent and 10% unknown type, 77% were treated with vitamin K antagonists (VKA), 17% with antiplatelet therapy with no differences between age groups. Rate-control drugs were more frequently used than rhythm-control drugs (55% vs. 37%, p < 0.001). VKA use was associated with permanent AF, younger age and cancer in patients ≥ 80 years old and with permanent AF and preserved functional autonomy in patients < 80 years old. Hemorrhagic scores were independently associated with non-use of VKA whereas thromboembolic scores were not associated with VKA use. CONCLUSIONS: In this elderly AF outpatient population, use of anticoagulant therapy was higher even after 80 years than in previous studies suggesting that recent international guidelines are better implemented in the elderly population.

The therapeutic management of chronic pain in ambulatory care patients aged 65 and over in France: the S.AGES Cohort. Baseline data.

OBJECTIVE: The main objective of the S.AGES (Elderly Subjects) cohort study is to describe the current therapeutic strategy for chronic pain in non-institutionalised elderly patients in France. METHODS: In this prospective cohort study, non-institutionalised patients aged 65 years and over with chronic pain were recruited by general practitioners (GP) across France. All medicinal and non- medicinal prescriptions were recorded at inclusion and will be followed up over 3 years via an eCRF. Data recorded at baseline are presented in this paper. RESULTS: Two hundred and sixty GPs enrolled 1379 evaluable patients between June 3rd, 2009 and June 3rd, 2011. Pain was mainly of a mechanical nature, due to osteoarthritis or common back pain. 80% of the patients had moderate or severe pain. More than a third of patients were treated with a step 1 analgesic (mainly paracetamol), and approximately 30% received a step 2 analgesic (23% dextropropoxyphene and 40.3% tramadol/paracetamol combination). Only 3% received step 3 analgesics; this rate remained low even in patients with severe pain. The proportion of patients treated with an antiepileptic was higher in case of neuropathic pain. More than 25% of patients did not receive any analgesic medication. CONCLUSION: The baseline S.AGES study results exhibit a well-balanced therapeutic management of chronic pain by GPs for ambulatory elderly patients. Clinicaltrials.org NCT01065909.

Promoting access to innovation for frail old persons. IAGG (International Association of Gerontology and Geriatrics), WHO (World Health Organization) and SFGG (Société Française de Gériatrie et de Gérontologie) Workshop--Athens January 20-21, 2012.

UNLABELLED: Frailty tends to be considered as a major risk for adverse outcomes in older persons, but some important aspects remain matter of debate. OBJECTIVES: The purpose of this paper is to present expert's positions on the main aspects of the frailty syndrome in the older persons. PARTICIPANTS: Workshop organized by International Association of Gerontology and Geriatrics (IAGG), World Health Organization (WHO) and Société Française de Gériatrie et de Gérontologie (SFGG). RESULTS: Frailty is widely recognized as an important risk factor for adverse health outcomes in older persons. This can be of particular value in evaluating non-disabled older persons with chronic diseases but today no operational definition has been established. Nutritional status, mobility, activity, strength, endurance, cognition, and mood have been proposed as markers of frailty. Another approach calculates a multidimensional score ranging from "very fit" to "severely frail", but it is difficult to apply into the medical practice. Frailty appears to be secondary to multiple conditions using multiple pathways leading to a vulnerability to a stressor. Biological (inflammation, loss of hormones), clinical (sarcopenia, osteoporosis etc.), as well as social factors (isolation, financial situation) are involved in the vulnerability process. In clinical practice, detection of frailty is of major interest in oncology because of the high prevalence of cancer in older persons and the bad tolerance of the drug therapies. Presence of frailty should also be taken into account in the definition of the cardiovascular risks in the older population. The experts of the workshop have listed the points reached an agreement and those must to be a priority for improving understanding and use of frailty syndrome in practice. CONCLUSION: Frailty in older adults is a syndrome corresponding to a vulnerability to a stressor. Diagnostic tools have been developed but none can integrate at the same time the large spectrum of factors and the simplicity asked by the clinical practice. An agreement with an international common definition is necessary to develop screening and to reduce the morbidity in older persons.

IAGG workshop: health promotion program on prevention of late onset dementia.

IAGG, WHO, and SFGG organized a international workshop on Health promotion programs on prevention of late on-set dementia. Thirty world specialists coming from Europe, North America, Asia, South America, Africa and Australia, shared their experience on methods and results of large epidemiological interventions to reduce incidents of dementia or delay its on-set. Chaired by Laura FRATIGLIONI, an expert in Epidemiological studies on dementia issues, the workshop gave opportunity for discussions and controversies about the state-of-the-art. Based on different national and international trials (ADAPT, MAPT, FINGER, GUDIAGE, GEM etc) the questions remained opened for different aspects of methodology, the choice of domain or multi domain intervention, the choice and the definition of the target populations, the best age of candidates, the issues related to the discrepancy between late effects, and interventions' duration. We are please to publish in the Journal, the presentations presented to this workshop. These publications will complete previously task force published in the journal in the last two years on methodological issues for Alzheimer's trials including end point, biomarkers, and the experience of past therapeutic trials.

Immediate and late benefits of treating very elderly people with hypertension: results from active treatment extension to Hypertension in the Very Elderly randomised controlled trial.

OBJECTIVE: To assess if very elderly people with hypertension obtain early benefit from antihypertensive treatment. DESIGN: One year open label active treatment extension of randomised controlled trial (Hypertension in the Very Elderly Trial (HYVET)). SETTING: Hospital and general practice based centres mainly in eastern and western Europe, China, and Tunisia. PARTICIPANTS: People on double blind treatment at the end of HYVET were eligible to enter the extension. INTERVENTIONS: Participants on active blood pressure lowering treatment continued taking active drug; those on placebo were given active blood pressure lowering treatment. The treatment regimen was as used in the main trial-indapamide SR 1.5 mg (plus perindopril 2-4 mg if required)-with the same target blood pressure of less than 150/80 mm Hg. MAIN OUTCOME MEASURES: The primary outcome was all stroke; other outcomes included total mortality, cardiovascular mortality, and cardiovascular events. RESULTS: Of 1882 people eligible for entry to the extension, 1712 (91%) agreed to participate. During the extension period, 1682 patient years were accrued. By six months, the difference in blood pressure between the two groups was 1.2/0.7 mm Hg. Comparing people previously treated with active drug and those previously on placebo, no significant differences were seen for stroke (n = 13; hazard ratio 1.92, 95% confidence interval 0.59 to 6.22) or cardiovascular events (n = 25; 0.78, 0.36 to 1.72). Differences were seen for total mortality (47 deaths; hazard ratio 0.48, 0.26 to 0.87; P = 0.02) and cardiovascular mortality (11 deaths; 0.19, 0.04 to 0.87; P = 0.03). CONCLUSION: Very elderly patients with hypertension may gain immediate benefit from treatment. Sustained differences in reductions of total mortality and cardiovascular mortality reinforce the benefits and support the need for early and long term treatment.

Implications of the Impact Survey for payors across Europe.

People involved with development of health care policy must be appreciative of the social and economic challenges that will likely develop as a result of the rise in Alzheimer's disease (AD) as the 21st century progresses. Their attitudes, perceptions and understanding regarding AD were captured in the IMPACT survey, a 30-minute Web-based questionnaire. Fifty health policy managers and decision-makers (payors) were recruited, 10 each from 5 European countries--France, Germany, Italy, Spain and the United Kingdom. Most payors felt that AD was underdiagnosed and undertreated in their country (80% and 68%, respectively). Half of all payors felt that their government did not invest enough in treating AD, and 30% felt their government hindered access to drug therapy. Payors believed that treatment should be initiated as early as possible after a diagnosis of AD (82%), and that early treatment can delay progression of the disease (82%). Even more than caregivers, payors agreed that AD can have devastating effects on the family of the sufferer (90% vs 75%; P<0.05). Payors more often cited cancer, stroke and heart disease than AD as affecting their budgets, but cited AD more often than depression, diabetes, HIV/AIDs and arthritis. Cost savings were seen as the most important factor regarding policy decisions. These attitudes of the surveyed payors towards AD and the patients and caregivers affected by it suggest that they may advocate for national and international policies that will facilitate earlier diagnosis and improved access to treatment.

Healthy working life expectancies at age 50 in Europe: a new indicator.

OBJECTIVES: The absence of disease or disability and active involvement in society are considered as essential dimensions of successful ageing. To assess these concepts, we propose a new indicator the Healthy Working Life Expectancy (HWLE) that associates health status and productive engagement, in order to compare various situations in Europe. DESIGN: The study population is drawn from the European Community Household Panel (ECHP) which is the unique source of longitudinal data, providing comparable information between 1995 and 2001 on health and work statuses for a sample of some 60,000 household's representative of the population of: Austria, Belgium, Denmark, Finland, France, Germany, the United Kingdom, Greece, Italy, the Netherlands, Portugal, and Spain. Based on the multi-state life table approach conventionally used for calculating healthy life expectancies, the HWLE corresponds to the number of years spent between the ages of 50 and 70 both in good health and at work. RESULTS: In average, among the 20 years available between age 50 and age 70, the HWLE is 7.5 years for men and 4.8 years for women, ie, one half and one third respectively of the number of years spent in good health (14.1 and 13.5 years). The countries where the healthy working life expectancy of seniors is the highest are also the countries where the levels of employment of seniors are higher. Conversely, health status has only a weak influence on the HWLE indicator. CONCLUSION: These findings suggest the existence of a reservoir of healthy years which can be used to increase the length of the working life expectancy. They underline also the essential role that employment maintenance and retirement policies should have to increase the number of healthy years spent at work, and therefore guarantee a successful ageing for the seniors in Europe.

Management of heart failure in the elderly: recommendations from the French Society of Cardiology (SFC) and the French Society of Gerontology and Geriatrics (SFGG).

Heart failure, a frequent disease in the elderly, has a pejorative prognosis. Clinical diagnosis is complicated by atypical or difficult-to-interpret symptoms and by the concomitant presence of other diseases, particularly cognitive impairment, neurological disorders and diseases of the musculoskeletal system. Among the additional investigations, echocardiography remains underused. Impairment of diastolic left ventricular function is frequent. The usual laboratory tests must include calculation of the creatinine clearance, which is indispensable for dosage adjustment of certain drugs (ACE inhibitors, digoxin, spironolactone). The value of plasma natriuretic peptide assays as diagnostic tools has not been determined in elderly or very elderly populations and the plasma B-type natriuretic peptide increases with age. Comprehensive geriatric assessment is essential in order to screen for concomitant diseases and determine the patient's degree of dependence. The general objectives of treatment remain applicable to the elderly subject: improvement in the quality of life, reduction of mortality and the number and duration of hospitalisations, and slowing disease progression. In the frail elderly subject, symptom alleviation is to be the primary objective. In the absence of specific studies on elderly or very elderly subjects, most of the recommendations have been extrapolated from the data based on the evidence generated in younger populations. The dietary rules are to be more flexible than those used for younger subjects, particularly in order to prevent the risk of denutrition induced by strict salt-free diets. Special precautions for the use of heart failure drugs are due to comorbidities and the pharmacokinetic and pharmacodynamic changes related to aging. Drugs dosage increase is to be cautious and carefully monitored for adverse reactions. The therapeutic programmes in which multidisciplinary teams are involved reduce the number and duration of hospitalisations and the costs generated by the disease.

[Consensus statement on severe dementia]. / Consensus sur la démence de type Alzheimer au stade sévère.

Under the auspices of the French Society of Gerontology and Geriatrics, a multidisciplinary group of experts, including geriatricians, neurologists, epidemiologists, psychiatrists, pharmacologists, and public health specialists developed consensus recommendations about care for patients with severe dementia. They defined 21 recommendations for general practitioners, long-term care physicians, and specialists, based on the knowledge currently available (2005). The aim of care at all stages is to mitigate the quality-of-life of patient, caregiver, and family insofar as possible, combining care and future planning until the end of life. Management, to take into account problems including nutritional status, behavior disorders, and ability (or inability) to perform activities of daily living, must be global, multidisciplinary, and coordinated and must optimize use of local medical and social resources. The group also stressed the importance of clinical research to improve knowledge of disease course and assess management strategies and recommended specific area for research.

[Consensus statement on severe dementia]. / Consensus sur la démence de type Alzheimer au stade sévère.

Under the auspices of the French Society of Gerontology and Geriatrics, a multidisciplinary team including geriatritians, neurologists, epidemiologists, psychiatrists, pharmacologists and public health specialists developed a consensus on care for patients with severe dementia. They defined 21 recommendations for general practitioners, long-term care physicians and specialists based on knowledge available in 2005. At all stages of the disease, the objective of care is to improve as much as possible quality-of-life for the patient and his/her family, including a life project until the end of life. It is always possible to do something for these patients and their family: nutritional status, behavior disorders, and incapacities to deal with basic activities of daily life have to be taken in consideration. Resource allocation and proximity care have to be targeted. Research areas necessary to improve the care of patients with severe dementia has been selected.

Clinical effects of Abeta immunization (AN1792) in patients with AD in an interrupted trial.

BACKGROUND: AN1792 (beta-amyloid [Abeta]1-42) immunization reduces Abeta plaque burden and preserves cognitive function in APP transgenic mice. The authors report the results of a phase IIa immunotherapy trial of AN1792(QS-21) in patients with mild to moderate Alzheimer disease (AD) that was interrupted because of meningoencephalitis in 6% of immunized patients. METHODS: This randomized, multicenter, placebo-controlled, double-blind trial of IM AN1792 225 microg plus the adjuvant QS-21 50 microg (300 patients) and saline (72 patients) included patients aged 50 to 85 years with probable AD, Mini-Mental State Examination (MMSE) 15 to 26. Injections were planned for months 0, 1, 3, 6, 9, and 12. Safety and tolerability were evaluated, and pilot efficacy (AD Assessment Scale-Cognitive Subscale [ADAS-Cog], MRI, neuropsychological test battery [NTB], CSF tau, and Abeta42) was assessed in anti-AN1792 antibody responder patients (immunoglobulin G titer > or = 1:2,200). RESULTS: Following reports of meningoencephalitis (overall 18/300 [6%]), immunization was stopped after one (2 patients), two (274 patients), or three (24 patients) injections. Of the 300 AN1792(QS-21)-treated patients, 59 (19.7%) developed the predetermined antibody response. Double-blind assessments were maintained for 12 months. No significant differences were found between antibody responder and placebo groups for ADAS-Cog, Disability Assessment for Dementia, Clinical Dementia Rating, MMSE, or Clinical Global Impression of Change, but analyses of the z-score composite across the NTB revealed differences favoring antibody responders (0.03 +/- 0.37 vs -0.20 +/- 0.45; p = 0.020). In the small subset of subjects who had CSF examinations, CSF tau was decreased in antibody responders (n = 11) vs placebo subjects (n = 10; p < 0.001). CONCLUSION: Although interrupted, this trial provides an indication that Abeta immunotherapy may be useful in Alzheimer disease.

Evolution of blood pressure in patients with Alzheimer's disease: a one year survey of a French Cohort (REAL.FR).

OBJECTIVES: To determine the evolution of blood pressure in patients with moderate Alzheimer's disease among a one year longitudinal survey and to evaluate the relationship between blood pressure and cognitive functions. METHODS: In 327 subjects selected from the French research program on Alzheimer's disease (REAL.FR), systolic and diastolic blood pressure (SBP, DBP) were measured at the time of inclusion (M0), after 6 months (M6) and after 12 months (M12). All subjects were assessed to determine both cognitive functions and capabilities in the activities of daily living using validated cognitive scales [Mini Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale--Cognitive part (ADAS-Cog), Instrumental Activities of Daily Living (IADL), Activities of Daily Living (ADL), Clinical Dementia Rating (CDR)], at M0, M6, M12. RESULTS: In this population of patients with moderate Alzheimer's disease, mean age was 78 +/- 7 years and 242 subjects were females (74%). After adjustment for age, gender, body mass index (BMI) and antihypertensive therapy, a significant decrease of blood pressure was observed between M0 and M12, for SBP (139.1 +/- 18 to 136.5 +/- 17 mmHg, p < 0.05) and DBP, (77.6 +/- 12 to 75.8 +/- 10 mmHg , p < 0.05). Demented subjects with the worst cognitive impairment at baseline (tertile1 MMSE, tertile 3 ADAS-Cog, ADL scores between 0 and 4, CDR scores between 10 to 18) showed a larger decrease in SBP and DBP after 12 months. The worst impairment in dementia at baseline was associated with the highest SBP decrease between M0 and M12 (delta SBP tertile 1 MMSE vs tertile 3 MMSE = -5.9 vs + 1.0 mmHg , p < 0.05; Delta SBP tertile 3 ADAS-Cog vs tertile 1 ADAS-Cog = - 5.98 vs + 2.98 mmHg, p < 0.05, Delta SBP ADL 0-4 vs ADL -6 = - 8.7 vs -1.5 mmHg, p < 0.05, delta SBP CDR 10-18 vs CDR 0.5-9.5 = - 6.9 vs -1.7 mmHg, p < 0.05). All these results persisted after adjustment for age, gender and the antihypertensive therapy. Baseline SBP [OR 95% CI = 1.05 (1.02-1.08), BMI [OR 95% CI = 0.88 (0.81-0.95)], ADL score [OR 95% CI = 0.42 (0.22-0.81)] and ADAS-Cog score [OR 95% CI = 1.07 (1.01-1.14)] were significantly associated with the decrease of blood pressure after one year of follow up, independently of age, gender and antihypertensive therapy. In contrast, patients with larger blood pressure decrease (over 10 mmHg reduction of SBP and/or 5 mmHg of DBP) did not demonstrate a more significant worsening of dementia at 12 months in the different scales used. CONCLUSIONS: This study indicates a significant decrease in blood pressure in patients with Alzheimer's disease after one year of follow up, independently of age, gender, BMI and antihypertensive therapy. The largest decrease in blood pressure was observed in patients with the most severe impairment in dementia at baseline, suggesting that blood pressure decrease seems to be mainly a secondary phenomenon in Alzheimer's disorders.

[Cognitive functions and hypertension]. / Fonctions cognitives et hypertension artérielle.

The prevention of cognitive disorders and dementia represents a major challenge in the coming years. Hypertension is one of the principal risk factors for cerebrovascular diseases and is also closely correlated with cognitive decline and dementia. Most longitudinal studies have shown that cognitive functioning is often inversely proportional to blood pressure values measured 15 or 20 years previously. The higher blood pressure was, the poorer cognitive function is. Data from recent therapeutic trials (SYST-EUR, PROGRESS) open the way toward the prevention of dementia (vascular or Alzheimer's type) by antihypertensive treatments. In this context, the effect of antihypertensive treatment on cognitive functions should represent one of the primary criteria of assessment in future morbidity and mortality studies in hypertensive patients.

Diuretics for cardiovascular prevention in the elderly.

High blood pressure (BP) is a major risk factor for cardiovascular and cerebrovascular diseases in elderly subjects. Antihypertensive drugs have shown clinical benefit both in primary and secondary prevention of cardiovascular events. If BP lowering represents the major determinant of the effects conferred by the antihypertensive treatment for prevention, recent studies have suggested some differences between classes of antihypertensive drugs according to age. Based on the available clinical data, the recent medical guidelines have recommended thiazide-type diuretics as the preferred drug for the treatment of elderly hypertensive patients, followed by long-acting calcium antagonists. Indeed, diuretics constitute one of the most valuable classes of antihypertensive drugs, and in the elderly, diuretic-based treatment studies have been clearly shown to prevent major cardiovascular events, including stroke, heart failure and coronary heart disease.
