RESUMEN
BACKGROUND: The association between the pattern of cortical thickness (CT) and executive dysfunction (ED) in mild cognitive impairment (MCI) and subjective cognitive complaints (SCC) is still poorly understood. We aimed to investigate the association between CT and ED in a large French cohort (MEMENTO) of 2323 participants with MCI or SCC. METHODS: All participants with available CT and executive function data (verbal fluency and Trail Making Test [TMT]) were selected (n=1924). Linear regressions were performed to determine relationships between executive performance and the brain parenchymal fraction (BPF) and CT using FreeSurfer. RESULTS: The global executive function score was related to the BPF (sß: 0.091, P<0.001) and CT in the right supramarginal (sß: 0.060, P=0.041) and right isthmus cingulate (sß: 0.062, P=0.011) regions. Literal verbal fluency was related to the BPF (sß: 0.125, P<0.001) and CT in the left parsorbitalis region (sß: 0.045, P=0.045). Semantic verbal fluency was related to the BPF (sß: 0.101, P<0.001) and CT in the right supramarginal region (sß: 0.061, P=0.042). The time difference between the TMT parts B and A was related to the BPF (sß: 0.048, P=0.045) and CT in the right precuneus (sß: 0.073, P=0.019) and right isthmus cingulate region (sß: 0.054, P=0.032). CONCLUSIONS: In a large clinically based cohort of participants presenting with either MCI or SCC (a potential early stage of Alzheimer's disease [AD]), ED was related to the BPF and CT in the left pars orbitalis, right precuneus, right supramarginal, and right isthmus cingulate regions. This pattern of lesions adds knowledge to the conventional anatomy of ED and could contribute to the early diagnosis of AD.
RESUMEN
Prevention of fragility fractures in older people has become a public health priority, although the most appropriate and cost-effective strategy remains unclear. In the present statement, the Interest Group on Falls and Fracture Prevention of the European Union Geriatric Medicine Society, in collaboration with the International Association of Gerontology and Geriatrics for the European Region, the European Union of Medical Specialists, and the International Osteoporosis Foundation-European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis, outlines its views on the main points in the current debate in relation to the primary and secondary prevention of falls, the diagnosis and treatment of bone fragility, and the place of combined falls and fracture liaison services for fracture prevention in older people.

AIMS OF THE STUDY: Stiffening of large arteries has been associated with increased cardiovascular outcomes among older subjects. Endurance exercises might attenuate artery stiffness, but little is known about the effects of intermittent training programme. We evaluate the effect of a short Intermittent Work Exercise Training Program (IWEP) on arterial stiffness estimated by the measure of the pulse wave velocity (PWV). METHODS AND SUBJECTS: Seventy-one healthy volunteers (mean age: 64.6 years) free of symptomatic cardiac and pulmonary disease performed a 9-week IWEP that consisted of a 30-min cycling twice a week over a 9-week period. Each session involved six 5-min bouts of exercise, each of the latter separated into 4-min cycling at the first ventilatory threshold alternated with 1-min cycling at 90% of the pretraining maximal tolerated power. Before and after the IWEP, the following measurements were made: carotid-radial PWV and carotid-femoral PWV with a tonometer and systolic and diastolic blood pressure. RESULTS: Training resulted in a non-significant decrease of the carotid-radial PWV, a significant decrease of the carotid-femoral PWV from 10.2 to 9.6 m/s (p < 0.001) (that was no longer significant after adjustment for mean arterial pressure) and a significant decrease in both systolic and diastolic blood pressure, respectively, from 129.6 ± 14.9 mmHg to 120.1 ± 14.1 mmHg (p < 0.001) and from 77.2 ± 8.8 mmHg to 71.4 ± 10.1 mmHg (p < 0.001). CONCLUSION: The present results support the idea that a short-term intermittent aerobic exercise programme may be an effective lifestyle intervention for reducing rapidly blood pressure and probably central arterial stiffness among older healthy subjects.

AIMS/HYPOTHESIS: Type 1 diabetic patients with diabetic nephropathy have increased mortality and morbidity compared with normoalbuminuric patients. Telomere length in proliferative cells is inversely related to the total number of cell divisions, and therefore to biological age. We aimed to evaluate differences in telomere length in patients with type 1 diabetes with or without diabetic nephropathy; we also evaluated the prognostic value of telomere length. METHODS: In a prospective follow-up study, 157 type 1 diabetic patients with diabetic nephropathy and a control group of 116 patients with type 1 diabetes and normoalbuminuria were followed for 11.1 years (range 0.2-12.9). Telomere length was measured from DNA samples extracted from white blood cells at baseline. RESULTS: The mean telomere length did not differ between patients with or without diabetic nephropathy, and was similar in men and women, but was inversely correlated with age and systolic blood pressure, p < 0.05. When dividing patients into tertiles after telomere length, 36 (37%) patients died in the tertile with the shortest telomere length, 24 (28%) died in the middle tertile, and 15 (17%) of patients in the tertile with the longest telomere length died, log rank test p = 0.017. After adjustment for traditional risk factors, telomere length was still predictive of all-cause mortality. CONCLUSIONS/INTERPRETATION: In patients with type 1 diabetes we found no differences in telomere length between patients with or without diabetic nephropathy. We also found that telomere length was associated with all-cause mortality; however, confirmative studies are needed to verify our findings.

BACKGROUND: The aim of the present study was to establish whether elevated carotid-femoral pulse wave velocity (c-fPWV), an indicator of aortic stiffness, assessed before surgery, is correlated with variations in arterial pressure (AP) during induction of anaesthesia in elderly patients undergoing non-cardiovascular surgery. METHODS: c-fPWV was measured with the PulsePen(®) device during pre-surgical anaesthetic evaluation. Monitoring included electrocardiography, pulse oximetry, non-invasive AP, heart rate, bispectral index (BIS), and oxygen concentration during induction of anaesthesia with propofol and remifentanil. Anaesthesia was induced so as to maintain BIS values between 40 and 50. RESULTS: Forty-five patients, aged [mean (sd)] 71.1 (5.8) yr, were studied. The mean value of c-fPWV was 12.1 (3.9) m s⻹. There was no correlation between hypotension during anaesthesia induction and total dosage or rate of administration of propofol or remifentanil. In univariate analysis, only age and PWV significantly correlated with the decreases in AP, and the association between c-fPWV and a decrease in AP was also seen in multivariate analysis (r = 0.36, P< 0.05). Patients classified as having 'high stiffness' (c-fPWV ≥ 12.9 m s⻹) had 25% further decrease in systolic AP during anaesthesia induction than those with lower PWV [75.2 (5.7) vs 60.2 (4.2) mm Hg, P < 0.05]. CONCLUSIONS: Increased aortic stiffness, as assessed by PWV measured during preoperative anaesthetic evaluation, is associated with more pronounced hypotension during induction of anaesthesia. Measurement of aortic stiffness in the elderly may thus represent a valid indicator of the risk of hypotension during anaesthesia induction.

OBJECTIVES: To propose a simple frailty screening tool able to identify frailty profiles. DESIGN: Cross-sectional observational study. SETTING: Participants were recruited in 3 different clinical settings: a primary care outpatient clinic (RURAL population, N=591), a geriatric day clinic (DAY-CLINIC population, N=76) and healthy volunteers (URBAN population, N=147). PARTICIPANTS: A total of 817 older adults (>70 years old) living at home were included. INTERVENTION: A 9-item questionnaire (Lorraine Frailty Profiling Screening Scale, LoFProSS), constructed by an experts' working group, was administered to participants by health professionals. MEASUREMENTS: A Multiple Correspondence Analysis (MCA) followed by a hierarchical clustering of the results of the MCA performed in each population was conducted to identify participant profiles based on their answers to LoFProSS. A response pattern algorithm was resultantly identified in the RURAL (main) population and subsequently applied to the URBAN and DAY-CLINIC populations and, in these populations, the two classification methods were compared. Finally, clinically-relevant profiles were generated and compared for their ability to similarly classify subjects. RESULTS: The response pattern differed between the 3 sub-populations for all 9 items, revealing significant intergroup differences (1.2±1.4 positive responses for URBAN vs. 2.1±1.3 for RURAL vs. 3.1±2.1 for DAY-CLINIC, all p<0.05). Five clusters were highlighted in the main RURAL population: "non-frail", "hospitalizations", "physical problems", "social isolation" and "behavioral", with similar clusters highlighted in the remaining two populations. Identification of the response pattern algorithm in the RURAL population yielded a second classification approach, with 83% of tested participants classified in the same cluster using the 2 different approaches. Three clinically-relevant profiles ("non-frail" profile, "physical frailty and diseases" profile and "cognitive-psychological frailty" profile) were subsequently generated from the 5 clusters. A similar double classification approach as above was applied to these 3 profiles revealing a very high percentage (95.6%) of similar profile classifications using both methods. CONCLUSION: The present results demonstrate the ability of LoFProSS to highlight 3 frailty-related profiles, in a consistent manner, among different older populations living at home. Such scale could represent an added value as a simple frailty screening tool for accelerated and better-targeted investigations and interventions.

SUMMARY: The role of body composition on arterial stiffness and osteoporosis remains unclear, especially in the elderly male population. Our results indicate that elderly men with high lean mass and low fat mass exhibit the best arterial and bone profile with the lowest arterial stiffness and the highest bone mineral density. INTRODUCTION: The aim of this study was to evaluate the influence of fat and lean mass on both arterial stiffness and bone mass density (BMD) in elderly men. METHODS: This study was performed in 169 French males over 60 years old. Aortic stiffness was assessed by carotid/femoral pulse wave velocity (PWV). BMD and body composition were determined with a dual-energy X-ray absorptiometry device in the lumbar spine L1-L4, femoral neck, and total body. RESULTS: Lean mass was positively correlated with the three T scores accounting for 11.6%, 26.6%, and 12.2% of the variability in the lumbar spine L1-L4, femoral neck, and total body BMD T scores, respectively. Fat mass had no effect on BMD. However, fat mass was positively correlated with aortic PWV, accounting for 9.8% of its variability. Lean mass was not a determinant of PWV. Hypertension, diabetes, and dyslipidemia were associated with higher PWV but had no effect on BMD. CONCLUSIONS: In males from a general population over 60 years of age, bone and arterial aging are differently influenced by lean and fat mass. Our results indicate that elderly men with high lean mass and low fat mass exhibit the best arterial and bone profile with the lowest arterial stiffness and the highest BMD.

Hypertension constitutes a recognized risk factor of vascular dementia but also of Alzheimer-type dementia. Various longitudinal studies showed that midlife blood pressure level is one of the factors conditioning the onset of dementia syndrome in late life. The high risk of dementia is linked to leukoaraiosis, vascular rigidity, microcirculation disorders, oxidative stress, blood pressure fluctuations including orthostatic hypotension and strokes, all of those being associated with hypertension. Numerous clinical trials showed the positive effect of effective treatment of hypertension on the prevention of cognitive disorders and dementias. Thus, screening and early management of dementia and cognitive decline, in particular in the hypertensive subject, are essential. The Mini-Mental State Examination (MMSE) is a major first-intention screening test because it allows a full assessment of cognitive aptitudes. If cognitive decline is suspected and the MMSE score is considered to be abnormal, the elderly subject must be sent to a specialist or a referent memory centre; the MMSE is only a first stage in the diagnostic reasoning. MMSE should be included in the follow-up of all hypertensive elderly subjects and should be performed once a year by the general practitioner.

Diagnosis of epileptic seizure may be difficult in older patients because seizure manifestations are often unusual: confusion, paresis... and because there are multiple differential diagnoses (syncope, transient ischemic attack, transient global amnesia...). To promote and facilitate the diagnosis of seizures in the elderly, neurologists and gerontologists must work together and focus their strategy on two points: firstly, the knowledge of the specific presentation of seizures in elderly patients, and secondly, the adoption of a reasoning based on seizures and not epileptic syndromes. A multidisciplinary group worked on epilepsy of the elderly to elaborate an electro-clinical score which aims to help establish the diagnosis of epilepsy in elderly patients in different clinical settings. This electro-clinical score is based on a systematic review of scientific literature and the recommendations are explicitly linked to supporting evidence. Further, clinical validation of the electro-clinical score is required.

Arterial stiffness, estimated by pulse wave velocity (PWV), is an independent predictor of cardiovascular mortality and morbidity. However, the clinical applicability of these measurements and the elaboration of reference PWV values are difficult due to differences between the various devices used. In a population of 50 subjects aged 20-84 years, we compared PWV measurements with three frequently used devices: the Complior and the PulsePen, both of which determine aortic PWV as the delay between carotid and femoral pressure wave and the PulseTrace, which estimates the Stiffness Index (SI) by analyzing photoplethysmographic waves acquired on the fingertip. PWV was measured twice by each device. Coefficient of variation of PWV was 12.3, 12.4 and 14.5% for PulsePen, Complior and PulseTrace, respectively. These measurements were compared with the reference method, that is, a simultaneous acquisition of pressure waves using two tonometers. High correlation coefficients with the reference method were observed for PulsePen (r = 0.99) and Complior (r = 0.83), whereas for PulseTrace correlation with the reference method was much lower (r = 0.55). Upon Bland-Altman analysis, mean differences of values +/- 2s.d. versus the reference method were -0.15 +/- 0.62 m/s, 2.09 +/- 2.68 m/s and -1.12 +/- 4.92 m/s, for PulsePen, Complior and Pulse-Trace, respectively. This study confirms the reliability of Complior and PulsePen devices in estimating PWV, while the SI determined by the PulseTrace device was found to be inappropriate as a surrogate of PWV. The present results indicate the urgent need for evaluation and comparison of the different devices to standardize PWV measurements and establish reference values.

OBJECTIVE: The aim of this review of the literature is to report the factors which both contribute to the frailty syndrome and increase hip fracture risk in the elderly. This work is the fruit of common reflection by geriatricians, endocrinologists, gynecologists and rheumatologists, and seeks to stress the importance of detection and management of the various components of frailty in elderly subjects who are followed and treated for osteoporosis. It also sets out to heighten awareness of the need for management of osteoporosis in the frail elderly. DESIGN: The current literature on frailty and its links with hip fracture was reviewed and discussed by the group. RESULTS: The factors and mechanisms which are common to both osteoporosis and frailty (falls, weight loss, sarcopenia, low physical activity, cognitive decline, depression, hormones such as testosterone, estrogens, insulin-like growth factor-I (IGF-I), growth hormone (GH), vitamin D and pro-inflammatory cytokines) were identified. The obstacles to access to diagnosis and treatment of osteoporosis in the frail elderly population and common therapeutic pathways for osteoporosis and frailty were discussed. CONCLUSION: Future research including frail subjects would improve our understanding of how management of frailty can can contribute to lower the incidence of fractures. In parallel, more systematic management of osteoporosis should reduce the risk of becoming frail in the elderly population.

OBJECTIVE: The SYMFONIE study was designed to analyze the clinical and biological characteristics, and the cardiovascular risk markers, in men and women with the metabolic syndrome compared to control subjects. RESEARCH DESIGN AND METHODS: The study population included 101,697 men and women, 18 to 80 years of age, who had a health checkup at the Centre d'Investigations Preventives et Cliniques (Paris, France) between 1997 to 2002. The metabolic syndrome was defined according to the ATpiiI-NCEP 2001 criteria. RESULTS: Out of the 66,202 men (47.4+/-11.8 years) and 35,495 women (48.5+/-13.6 years) included in this population, 6761 men (10.2%) and 2155 women (6.1%) presented the metabolic syndrome. Among subjects < or =40 years of age, the prevalence of the metabolic syndrome was 5.0% in men and 2.2% in women, and rose to 14.1% and 12.0%, respectively, among men and women >70 years of age. After adjustment for age, patients with the metabolic syndrome presented higher pulse pressure (systolic minus diastolic blood pressure), higher heart rate, lower vital respiratory capacity, lower physical activity, an increase in inflammatory status assessed through leukocyte count and dental inflammation, hepatic abnormalities, and increased levels of stress and depression. CONCLUSION: In this large French population, the prevalence of the metabolic syndrome is lower than in North American and northern European populations. Patients with the metabolic syndrome present several additional hemodynamic, inflammatory and psychological risk markers which could contribute to the poor cardiovascular prognosis of these subjects.

Arterial stiffness assessed by the pulse wave velocity (PWV), a non-invasive and reproducible method, predicts cardiovascular morbidity and mortality. The main determinants of arterial stiffness are well established in younger and middle-aged populations, but much less in the elderly. The aim of this study was to describe the determinants of arterial stiffness in elderly apparently healthy subjects. The study included 221 voluntary subjects born before 1944 (mean age 67.4+/-5.0 years), who had a standard health check-up at the 'Centre de Médecine Préventive' of Nancy. Arterial stiffness was evaluated by measuring the carotid-femoral PWV with the PulsePen automatic device. Clinical and biological parameters were evaluated at the same day. Measurements were valid and analysed in 207 subjects (94 women). Mean PWV was 9.39+/-2.64 m/s. Men showed higher PWV values than women (9.99+/-2.56 vs 8.66+/-2.56, P<0.001). In univariate analysis, PWV was correlated with age (r=0.26, P<0.001) and mean arterial pressure (MAP) (r=0.40, P<0.001), and these relationships were similar in men and women. Subjects with hypertension (P<0.001), diabetes mellitus (P<0.001) and obesity (P<0.01) had higher values of PWV. In multiple regression analysis, PWV correlated positively and independently with age, male gender, MAP and diabetes mellitus. In conclusion, in an apparently healthy elderly population, the main determinants of arterial stiffness are the age, MAP, diabetes and gender. Our study also shows that the gender-related differences in arterial stiffness observed in middle-aged subjects are maintained in the elderly.

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.

Unstable angina and acute coronary syndromes (ACS) without ST-segment elevation are frequent in the elderly and is associated to a very poor prognosis. The cause of mortality excess in the elderly has not yet been fully elucidated, even though the numerous comorbidities present in this age range play a non-negligible role. In every case, age is the most powerful prognostic factor for ACS without ST-segment elevation. The presentation and clinical characteristics of coronary disease in the elderly are particular and are essential to be recognized. Patients are mostly women with history of heart failure and myocardial infarction, and risk factors are predominantly diabetes and hypertension. The usual presentation is a "silent" MI or with atypical symptoms. Instead of typical chest pain, the coronary artery disease will be presented by dyspnea, neurological symptoms such as confusion, cognitive disorders aggravation, digestive disorders. This atypical presentation will have direct consequences on the therapeutic management of ACS, and sometimes it will even remain undiagnosed, and these explain also why complications will be more severe than in younger counterparts. Due to this atypical presentation, the physician should be careful and suspect an ACS in case of any non-explicated modification of physical and behavioral change in the elderly.

PURPOSE: The prevalence or hypertension increases with aging, reaching more than 50% in people aged 60 years and older. The increase of systolic blood pressure is a major risk of cardiovascular event. METHODS: With the aim of assessing risk factors in old people "in apparent good health", we analysed blood pressure and treatments in people aged 60 years and older who had a periodic check-up that was adapted to older people. RESULTS: This check-up concerned, between April and December 2003, 1638 people with a mean age of 68 years (SD 5.7): 815 men and 823 women. Fourty percent had a systolic blood pressure (SBP) >or=140 mmHg (44% of men, 36% of women); 6% (8% of men, 4% of women) had a diastolic blood pressure (DBP) >or=90 mmHg. A treatment for hypertension was followed by 473 people: 31% of men and 26% of women. Fifty percent were controlled for the SBP and the DBP. Fourty-two percent were not controlled for the SBP, but were controlled for the DBP. Seven percent were not controlled for the SBP nor the DBP. Only 3 subjects (<1%) were not controlled for the DBP, whereas they were controlled for SBP. CONCLUSION: These results, combined with data of literature on the predominant role of SBP in cardio-vascular risk, as compared with DBP, underline the need for a better treatment of systolic hypertension in older people.

The treatment of isolated systolic hypertension (ISH) in the elderly reduces the cardiovascular (CV) risk, in particular in patients with diabetes or previous CV events. However, in the very old (> 80-85 years) the treatment of ISH may increase global mortality, although it still decreases the risk of stroke. The benefits of treatment on the risk of dementia remain uncertain. To verify the indication for therapy, the diagnosis of ISH should be confirmed by ambulatory blood pressure monitoring. Since the absolute benefit of treatment is related to its duration, a limited life expectancy may restrict the real impact of treatment. The advantages and limitations of anti-hypertensive therapy in the elderly should be discussed individually, respecting the patient's autonomy.

BACKGROUND: Vascular aging is accompanied by gradual remodeling affecting both arterial and cardiac structure and mechanical properties. Hypertension is suggested to exert pro-inflammatory actions enhancing arterial stiffness. OBJECTIVE: To determine the influence of thoracic aortic inflammation and calcifications on arterial stiffness and cardiac function in hypertensive and normotensive older subjects. DESIGN: A prospective study. SETTING: An acute geriatrics ward of the University Hospital of Nancy in France. SUBJECTS: Thirty individuals ≥ 65 years were examined, including 15 hypertensive subjects and 15 controls well-matched for age and sex. MEASUREMENTS: Applanation tonometry was used to measure aortic pulse wave velocity (AoPWV) and carotid/brachial pulse pressure amplification (PPA). Left ventricular parameters were measured with magnetic resonance imaging. Local thoracic aortic inflammation and calcification were measured by 18 F-fluorodeoxyglucose positron emission tomography/computed tomography imaging. Biomarkers of low-grade inflammation were also quantified. RESULTS: AoPWV was higher in elderly hypertensive subjects comparatively to normotensive controls (15.5±5.3 vs. 11.9±2.5, p=0.046), and hypertensives had a higher calcification volume. In the overall population, calcifications of the thoracic descending aorta and inflammation of the ascending aorta accounted for respectively 18.1% (p=0.01) and 9.6% (p=0.07) of AoPWV variation. Individuals with high levels of calcifications and/or inflammation had higher AoPWV (p=0.003). Inflammation had a negative effect on PPA explaining 13.8% of its variation (p<0.05). CONCLUSION: This study highlights the importance of local ascending aortic inflammation as a potential major actor in the determination of PPA while calcifications and hypertension are more linked to AoPWV. Assessment of PPA in the very elderly could provide complementary information to improve diagnostic and therapeutic strategies targeting ascending aortic inflammation.
