Resumen La anorexia y la perdida de peso son sintomas comunes en geriatria, con graves consecuencias en terminos de morbimortalidad y de pronostico funcional. Las causas mas frecuentes son las etiologias oncologicas, los trastornos gastrointestinales benignos, los trastornos psiquiatricos y las enfermedades neurocognitivas. Sin embargo, muchos factores geriatricos predisponen a este riesgo y deben ser investigados. Para ello, la «regla de las 9D» ofrece una vision exhaustiva y rapida de estos factores: drugs (farmacos), depresion, demencia, disfagia, disgeusia, denticion, disfuncion (discapacidades funcionales), disease (enfermedades agudas o cronicas), diarrea. Se requiere una exploracion fisica rigurosa para tratar de identificar la etiologia. Algunas pruebas complementarias, guiados por la exploracion fisica, pueden ayudar en el diagnostico. Sin embargo, en el 25% de los casos no se encuentra la etiologia. El tratamiento consiste en tratar la causa, al tiempo que se implementa el soporte nutricional adecuado. Tambien es esencial una evaluacion geriatrica global para poner de manifiesto todos los factores que predisponen a la anorexia o a la perdida de peso con el fin de proponer medidas de apoyo multimodales.

Background/Introduction Age is one of the strongest predictors/risk factors for ischemic stroke in subjects with atrial fibrillation (AF). Direct oral anticoagulants (DOACs) have been shown to be effective in the prevention of this condition; however, clinical evidence on bleeding risk with this therapeutic strategy in very old and frail geriatric patients is poor. Purpose To assess bleeding risk in French geriatric patients aged ≥80 years and diagnosed with AF newly treated with rivaroxaban. Methods Subjects, presenting to one of 33 geriatric centers, with non-valvular AF and recent initiation of a treatment with rivaroxaban were enrolled in the study and followed-up every 3 months for 12 months. Clinical and routine laboratory data and evaluation scores, such as HAS-BLED, HEMORR2HAGES, ATRIA, and CHA2DS2-VASc, as well as comprehensive geriatric evaluation were reported. Major bleeding, as defined in ROCKET AF study, was reported at each visit, and this primary outcome was adjudicated by an independent committee. Results of this cohort were compared with findings from a similar cohort treated with vitamin K antagonists (VKAs) from the same centers (n=924). Results A total of 1045 subjects were enrolled in the study of whom 995 (95%) had a one-year follow-up (analyzed population). The mean (standard deviation (SD)) age was 86.0 (4.3) years, with the majority of patients being female (61%), 23% aged 90 years or older, and 48% having an estimated glomerular filtration rate (eGFR) Conclusions This is the first large-scale prospective study in geriatric population in AF subjects treated with DOAC (rivaroxaban) Major bleeding risk appeared higher in very old than younger population, however major bleeding and ICH rates were significantly lower with rivaroxaban than with VKAs when used in the same geriatric population. This study indicates that Rivaroxaban can be used in very old and frail patients for the treatment of non-valvular AF. Acknowledgement/Funding Unrestricted grant from Bayer

Previous studies have shown controversial results of factors associated with short-term mortality in patients with extended-spectrum beta-lactamase (ESBL)-producing E. coli bacteremia and no research has investigated the impact of the geriatric assessment criteria on short-term mortality. Our objective was to determine whether dementia and walking ability are associated with 30-day mortality in patients with ESBL-producing E. coli bacteremia. All blood bottle cultures, analyzed from January 2008 to April 2015, in the Bacteriology Department of a 2,600-bed, university-affiliated center, Nantes, France, were retrospectively extracted. Factors associated with short-term mortality in patients with ESBL-producing E. coli bacteremia: 140 patients with an ESBL-producing E. coli bloodstream infection were included; 22 (15.7%) patients died within 30 days following the first positive blood bottle culture of ESBL-producing E.coli. In multivariate analysis, a reduced ability to walk (OR = 0.30; p = 0.021), presence of dementia (OR = 54.51; p = 0.040), a high Sepsis-related Organ Failure Assessment (SOFA) score (OR = 1.69; p

International audience; Background: Transcatheter aortic-valve implantation (TAVI) has been shown to improve survival and quality of life in patients with severe aortic stenosis. However, one-third of patients have poor outcome as death, functional decline or quality of life (QoL) decline. The aim of this study was to determine cardiac and geriatric predictors of physical and mental QoL decline 6 months after a TAVI procedure in patients aged 75 and older.Methods: Between January 2013 and June 2014, we did a prospective and multicenter study including patients ≥ 75 years old referred for TAVI. The primary outcome was the measure of QoL, assessed by the Short Form 36 survey (SF-36), before and 6 months after the intervention. Association between QoL decline and baseline characteristics including cardiac and geriatric factors was analysed by logistic regression models.Results: Mean age of the 150 patients studied was 83.7 years old and 56% were men. The primary end point, mean SF-36 physical summary score, significantly improved between baseline and 6-month (33.6 vs. 36.4, p=0.003) whereas mental component score significantly decreased (48.2 vs. 36.4, p-value

International audience; Elderly people are more likely to develop severe infections diseases. Given the significant increase in the number of the elderly population, reducing the risk of infection by vaccination is a major preventive approach. The immunization schedule for 2014 in France yields, for the first time, vaccination recommendations for patients over 65 years. Tetanus-Diphtheria-Poliomyelitis vaccination is recommended to be given at the age of 65 years and then every 10 years, together with the pertussis vaccine to protect infants less than 6 months. Recommendation for vaccinations against seasonal influenza in autumn is maintained by the High Council for Public Health, which estimates that the population benefit persists despite the lower individual effectiveness in the elderly. The pneumococcal vaccine is recommended only in high-risk populations, and only once after the age 65. Zoster vaccine is recommended between 65 and 74, and the first year of its availability, can be proposed to elderly patients between 75 and 79 years. Vaccination in the elderly must be enhanced, and information about its advantages should be disseminated.

La prevention de la decompensation des situations a risque necessite une evaluation du niveau de risque que ce soit par une evaluation geriatrique standardisee ou le reperage de la fragilite, en fonction du contexte. La prevention doit egalement etre consideree dans le cadre plus large des coordinations gerontologiques et des dispositifs de prise en charge a l’echelle des territoires tels que l’integration des services. On distingue la prevention des affections qui peuvent, de maniere isolee, provoquer une decompensation de la situation sanitaire et sociale de la personne âgee. Dans ce cadre la prevention comprend l’arret des conduites a risque (tabac, alcool), le traitement des facteurs de risque cardiovasculaire (hypertension arterielle [HTA], hypercholesterolemie), de la surveillance du diabete, de la prevention des fractures osteoporotiques. Chez la personne âgee souvent polymediquee, la qualite des prescriptions medicamenteuses, l’education therapeutique et l’amelioration de l’observance sont essentielles a la prevention des decompensations liees au risque iatrogene. Chez les sujets âges dont la fragilite represente de fait une elevation potentielle du niveau de risque, la prevention comprend le maintien d’une activite physique adaptee, l’equilibre nutritionnel proteinoenergetique, la correction des deficiences sensorielles, la prevention des risques psychosociaux et, lors d’une alteration cognitive, une stimulation cognitive. L’ensemble devra etre associe a une demarche multidomaine. Les politiques de prevention sociale en sont un complement essentiel.

International audience; BackgroundThe aim of this study was to determine the level of adherence to oral anticoagulants in the population of elderly patients treated for a non-valvular atrial fibrillation (AF) in the era of direct oral anticoagulants.Patients and methodThis transversal study used Morisky scale to assess adherence to oral anticoagulants. We also collected patients’ reviews about the treatment and factors explaining a poor adherence.ResultsBetween January and June 2015, 64 patients were included in Loire Atlantique. Average age was 77.8 years, CHA2DS2-VASc score was 4.06 and treatment (vitamin K antagonists [VKAs] in 78% patients) was prescribed since 4.3 years. According to Morisky scale, 84.4% of patients had a good adherence. There was 88% of good adherence with AVK versus 71% with direct oral anticoagulant, there was no statistically significant difference. The prescriber and the knowledge of anticoagulant treatment role seemed to be determinant factors.ConclusionsThe level of adherence for oral anticoagulant appears higher than in most published studies. Diversification of therapeutic options could constitute an aid to personalize the prescription in order to improve it.; ObjectifL’objectif de cette étude était de déterminer un niveau d’observance du traitement anticoagulant oral, dans la population des patients de plus de 65 ans traités dans le cadre d’une fibrillation atriale (FA) non valvulaire, à l’ère des anticoagulants oraux directs (AOD).Patients et méthodeCette étude transversale utilisait le questionnaire de Morisky pour évaluer l’observance du traitement anticoagulant oral. L’avis du patient sur son traitement ainsi que les facteurs qu’il évoquait pour expliquer une mauvaise observance ont été recueillis.RésultatsEntre janvier et juin 2015, 64 patients ont été interrogés en Loire Atlantique. L’âge moyen était de 77,8 ans, le score CHA2DS2-VASc de 4,06 et le traitement (antivitamine K [AVK] dans 78 % des cas) était prescrit depuis 4,3 ans. Selon le questionnaire de Morisky, 84,4 % des patients étaient « bons observants ». Il y avait 88 % de « bons observants » sous AVK versus 71 % sous AOD, sans différence statistique significative. Le prescripteur initial ainsi que la connaissance du rôle du traitement anticoagulant semblaient être des facteurs déterminants.

The perceptual inhibitory process has been suggested to be specifically involved in the integration of proprioceptive information that is necessary for an efficient postural performance in older adults. This ongoing study aimed to investigate the perceptual and motor inhibition requirements of planning and executing a choice step initiation task in young and older adults following experimental perturbation of proprioceptive information using bilateral Achilles’ tendon vibrations. Two groups (n~50 each) of young adults (range age 18–30 years), and healthy older adults (>65 years of age) were asked to perform an inhibitory stepping reaction time (RT) task in which the participants had to step as quickly as possible in response to visual arrows that manipulated specific perceptual or motor inhibition, in two conditions: with or without vibrations. The preliminary results (up-to-date n~10) showed that the vibrations induced higher RT performances irrespective of the perceptual or motor inhibition demands. Any specific role of the perceptual inhibition into the processing of proprioceptive inputs needs to be confirmed in healthy older adults. Compared to younger adults, older adults have greater variability in step behaviour, with longer total stepping time, when using localized vibrations in conditions requiring inhibition. More participants continue to be included to determine robustly whether modulating afferent proprioceptive inputs and inhibition are two processes that share, at least in part, the same cognitive resources in older adults, while executing a choice step. But the current results validate the view that inhibitory process is a core executive function of dynamic postural control.

The burden of hypoglycaemia is important, particularly in elderly type 2 diabetes (T2D) patients. Unfortunately, however, few studies are available concerning this population. GERODIAB is a prospective, multicentre, observational study that aims to describe the 5-year morbidity and mortality of 987 T2D patients aged 70 years and older. After analyzing the frequency of and factors associated with hypoglycaemia in the 6 months prior to study inclusion, it was found that hypoglycaemia was associated with retinopathy, lower levels of LDL cholesterol and altered mini-Geriatric Depression Scale (GDS) scores.

Introduction Les recommandations recentes de prise en charge du diabete de type 2 (T2DM) chez le sujet âge preconisent une adaptation de la cible therapeutique (HbA1c) a l’etat de sante du sujet. L’objectif de l’etude etait d’explorer l’association entre l’atteinte de la cible therapeutique personnalisee et la survenue d’evenements cliniques chez des patients âges diabetiques en conditions de vie reelle. Patients et methodes La sous-cohorte SAGES diabete est une etude prospective multicentrique ou 213 medecins generalistes ont inclus 983 patients diabetiques de type II âges de plus de 65 ans non institutionnalises. L’objectif personnalise d’HbA1c recommande etait Resultats Parmi les 747 patients analyses a l’inclusion, 551 (76,8 %) atteignaient la cible therapeutique personnalisee d’HbA1c. Durant le suivi, 391 patients (52,3 %) ont presente au moins un evenement clinique majeur. Parmi les patients n’atteignaient par leur cible personnalisee d’HbA1c (compares a ceux qui l’atteignaient), le risque (OR) de presenter un evenement clinique majeur etait de 0,95 [IC95 % 0,69–1,31], p = 0,76. Les risques de deces, d’evenements arteriels et d’hospitalisations etaient respectivement 0,88 [IC95 % 0,40–1,94], p = 0,75, 1,14 [IC95 % 0,71–1,83], p = 0,59 et 0,84 [IC95 % 0,60–1,18], p = 0,32. Conclusion Durant les trois ans de suivi, le fait de ne pas atteindre la cible personnalisee d’HbA1c n’etait pas associe a un exces de risque d’evenements cliniques. Ces resultats suggerent qu’une strategie moins intensive pour traiter le diabete serait appropriee pour les patients âges.

Summary Background & aims Hydration disorders are frequent in clinical practice and can be a life threatening issue in frail patients. Mild dehydration (1–2% loss of body weight) appears to impair cognitive and muscular performance. There is, however, no infallible indicator of correct hydration, and of hydration disorders. This study aim at describing total body water (TBW), extra-cellular water (ECW) and intracellular water (ICW) in a cohort of healthy subjects varying in age, gender and body composition. Two indicators of cellular hydration (TBW over fat free mass, and ICW over fat free mass) were studied. Methods The study cohort was made of 944 men and 874 women (mean age 42.7±13.1 yrs, BMI 24.3±3.5kg/m 2 ). All were volunteers for a preventive health examination. TBW, ECW, ICW were measured with bioelectrical impedance analysis. Body composition was assessed with the 3-compartment model. Results Values for TBW, ECW, and ICW differed with gender and with BMI categories (lean, overweight, and obese). The ratio of TBW over weight decreased with increasing BMI and was lower in women than in men. ECW (as a proportion of TBW) increased with BMI. The ratio of TBW over fat free mass decreased in obese subjects. The ratio of ICW over fat free mass was normally distributed, and decreased with BMI, more so in women than in men. Conclusions This study provides reference values for body water spaces in healthy adults that are negatively correlated with BMI. Women and obese people display indicators of cellular dehydration, and are more at risk of dehydration.

Resume Le dosage de l'excretion urinaire d'albumine (EUA) peut se faire sur un echantillon urinaire sur les premieres urines du matin, sur les urines de 24 heures ou sur prelevement urinaire minute. Les valeurs definissant la microalbuminurie sont : urines de 24 heures : 30–300 mg/24 h ; echantillon urinaire : 20–200 mg/ml ou 30–300 mg/g creatinine urinaire ou 2,5–25 mg/mol (chez l'homme), ou 3,5–35 mg/mol (chez la femme) creatinine urinaire ; echantillon urinaire minute : 20–200 μg/min. La place du dosage semi-quantitatif (bandelettes) n'est pas clairement definie. La microalbuminurie est consideree comme un reflet d'une atteinte generalisee de l'endothelium, mais ce n'est pas demontre. Chez le sujet diabetique La microalbuminurie est un marqueur independant de risque cardiovasculaire (CV), renal et de mortalite totale chez les diabetiques de type 1 et 2. L'augmentation de l'EUA au cours du temps est un marqueur de risque CV et renal chez le diabetique de type 1 ; sa regression est associee a une regression de ces risques. Chez le sujet non diabetique La microalbuminurie est un marqueur independant de risque CV, de risque de diabete, d'alteration de la fonction renale et de mortalite totale. Elle est un marqueur de risque de developper une hypertension arterielle chez le sujet normotendu et un marqueur de risque d'evolution defavorable, ou de deces au cours de cancers et de lymphomes. L'elevation ou la persistance d'une EUA elevee au cours du temps est associee a un pronostic pejoratif chez certains hypertendus. La mesure d'EUA peut etre recommandee chez certains hypertendus ayant un ou deux facteurs de risque CV associes dont le risque CV semble mal evalue ou ayant une hypertension arterielle (HTA) refractaire : la microalbuminurie indique ici un risque CV eleve et incite a assurer un controle tensionnel strict. Il y a peu d'etudes chez les sujets non hypertendus et non diabetiques ; elles suggerent globalement que la microalbuminurie est un facteur de comorbidite et de mauvais pronostic comme chez les sujets hypertendus ou diabetiques. En prevention secondaire, la microalbuminurie est un marqueur de risque independant, mais n'a pas de retombees therapeutiques specifiques. Il n'est pas recommande de rechercher systematiquement une microalbuminurie chez le sujet non hypertendu, non diabetique, sans antecedent de maladie renale. Il est recommande d'effectuer une surveillance de la fonction renale annuelle (excretion urinaire d'albumine creatininemie et estimation du debit de filtration glomerulaire) chez les sujets microalbuminuriques. Therapeutique Chez tout patient ayant une microalbuminurie : reduction ponderale et de l'apport sode excessif ( chez le diabetique , prescription d'un inhibiteur de l'enzyme de conversion (diabete de type 1) ou d'un antagoniste des recepteurs de l'angiotensine 2 (diabete de type 2) a dose suffisante en premiere intention. Les diuretiques thiazidiques ont un effet synergique avec les bloqueurs du systeme renine angiotensine sur la reduction de l'EUA ; chez le non diabetique , les cinq grandes classes d'antihypertenseurs (IEC, ARA2, diuretiques, antagonistes calciques, betabloquants) sont utilisables en premiere intention.

Summary Background & Aims Knee-heel length has been validated in elderly patients as a means to estimate body height. It is accurate and conveys a sufficient precision when it is used to calculate body mass index, and body surface area. This study was undertaken to validate body height estimated from knee-heel length in middle age Caucasian adults. Methods A population of 2789 subjects was recruited in health care centres. They had a measurement of body height, knee-heel length and body weight. Results Knee-heel length was positively correlated with body weight ( r =0.52, p r =0.83, p r =−0.12, p p p 2 of body mass index (BMI) for 41% of population. Conclusions Knee-heel length is not recommended to estimate body height in middle age adults. Alternative methods should be studied.

Resume Sous l’egide de la Societe Francaise de Geriatrie et Gerontologie, un groupe pluridisciplinaire de specialistes en geriatrie, neurologie, epidemiologie, psychiatrie, neuroradiologie, pharmacologie, sante publique a entrepris une demarche de consensus sur les modalites d’evaluation, de suivi et de prise en charge globale de la demence de type Alzheimer au stade severe. Cette reflexion, fondee sur l’etat des connaissances en 2005, a permis de formuler 21 recommandations a destination des praticiens hospitaliers, medecins traitants, medecins coordonnateurs et specialistes. Quel que soit le stade evolutif de la maladie, l’objectif de la prise en charge est d’ameliorer la qualite de vie de la personne malade et de sa famille, en associant projet de soins et projet de vie et ce jusqu’en fin de vie. La prise en charge, pour etre globale, doit etre necessairement pluridisciplinaire et coordonnee, en mobilisant les ressources sanitaires et medico-sociales de proximite pour optimiser leur utilisation. Le groupe a souligne egalement l’importance d’une recherche dynamique : recherche clinique visant a mieux connaitre l’evolution des troubles, evaluation des strategies de prise en soins.

Abstract —Hyperglycemia causes capillary vasodilation and high glomerular capillary hydraulic pressure, which lead to glomerulosclerosis and hypertension in type 1 diabetic subjects. The insertion/deletion (I/D) polymorphism of the angiotensin I–converting enzyme (ACE) gene can modulate risk of nephropathy due to hyperglycemia, and the II genotype (producing low plasma ACE concentrations and probably reduced renal angiotensin II generation and kinin inactivation) may protect against diabetic nephropathy. We tested the possible interaction between ACE I/D polymorphism and uncontrolled type 1 diabetes by measuring glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) during normoglycemia (≈5 mmol/L) and hyperglycemia (≈15 mmol/L) in 9 normoalbuminuric, normotensive type 1 diabetic subjects with the II genotype and 18 matched controls with the ID or DD genotype. Baseline GFR (145±22 mL/min per 1.73 m 2 ) and ERPF (636±69 mL/min per 1.73 m 2 ) of II subjects declined by 8±10% and 10±9%, respectively, during hyperglycemia; whereas baseline GFR (138±16 mL/min per 1.73 m 2 ) and ERPF (607±93 mL/min per 1.73 m 2 ) increased by 4±7% and 6±11%, respectively, in ID and DD subjects (II versus ID or DD subjects: P =0.0007 and P =0.0005, for GFR and ERPF, respectively). The changes in renal hemodynamics of subjects carrying 1 or 2 D alleles were compatible, with a mainly preglomerular vasodilation induced by hyperglycemia, proportional to plasma ACE concentration ( P =0.024); this was not observed in subjects with the II genotype. Thus, type 1 diabetic individuals with the II genotype are resistant to glomerular changes induced by hyperglycemia, providing a basis for their reduced risk of nephropathy.

Aortic stiffness is a functional and structural consequence of ageing and arteriosclerosis. Regional arterial stiffness can be easily evaluated using pOpmetre(®) (Axelife SAS, France). This new technique assesses the pulse wave transit time (TT) between the finger (TTf) and the toe (TTt). Based on height chart, regional pulse wave velocity (PWV) between the toe and the finger can be estimated (PWVtf). pOpscore(®) index is also calculated as the ratio between PWVtoe and PWVfinger and can be considered as a peripheral vascular stiffness index. The aim of the study was to evaluate the relationship between pOpmetre(®) indices and the presence of carotid plaques in a population with cardiovascular risk factors.In 77 consecutive patients recruited for a vascular screening for atherosclerosis (46 men aged 54 ± 2 years; 31 women aged 49 ± 3 years; ns), the difference between TTt and TTf (called Dt-f), the regional pulse wave velocity between the toe and the finger (PWVtf = constant × height/Dt-fm/s) and pOpscore(®) were measured by pOpmetre(®). Presence of carotid plaques was assessed using ultrasound imaging. The local aortic stiffness (AoStiff) was evaluated by the Physioflow(®) system.No difference was found between patients with or without carotid plaques (n=25 versus 52) for Ankle-Brachial Pressure Index (ABPI: 1.15 ± 0.04 versus 1.12 ± 0.03), nor for diastolic or systolic blood pressure (87 ± 3 versus 82 ± 2; 137 ± 3 versus 132 ± 2 mmHg). The first group was older than the second (59 ± 2 versus 49 ± 2 years, P0.002) with a larger intimae media thickness (0.69 ± 0.02 versus 0.63 ± 0.01 mm, P0.004), a higher AoStiff (10.4 ± 0.7 versus 8.2 ± 0.5m/s, P0.02), and PWVtf (14.3 ± 1.0 versus 10.7 ± 0.7 m/s, P0.004) and a shorter Dt-f (57.9 ± 5.1 versus 73.5 ± 3.5 ms, P0.01). PWVtf (r(2)=0.49, P0.0001) and Dt-f (r(2)=0.54, P0.0001) correlated with age. A significant difference in pOpscore(®) index was observed between both groups (1.51 ± 0.3 versus 1.41 ± 0.2, P0.006).Our results show a significant arterial stiffness indices measured by pOpmetre(®) in patients with and without carotid plaques.

The definition of normal pressure hydrocephalus (NPH), in adults, associates clinical signs (Adams and Hakim triad) involving gait disorders, urinary incontinence and dementia, associated with aspects on brain imaging that are consistent with this hypothesis and also normal or slightly increased intracranial pressure. The aim of this study was to clarify the techniques and methods facilitating the diagnosis of NPH. The literature review has been conducted from the Medline database without date limitation including the keywords "normal pressure hydrocephalus" and "diagnosis." They should appear in the article title. From the 43 initially sorted, only 13 have been selected using exclusion criteria. The proposed methods are very sparse and focused on the improvement after surgical shunt. This focus is independent from the diagnosis criteria proposed in 2005. This introduces an ambiguity in the interpretation of the results. In practice, the diagnosis of NPH is more difficult in the elderly population where differential diagnoses are frequent, particularly vascular lesions (notably microangiopathy) and Alzheimer's disease. The more invasive techniques as continuous spinal drainage (usually during 3 days) or some features of CSF dynamics (Rout, compliance) seem to be the best predictors of after shunt improvement. However, these techniques are difficult to use in routine in the elderly. The combination of Evans index and corpus callosum angle on MRI is very useful to improve the differential diagnosis with cerebral atrophy. Spinal tap test (lumbar puncture with the removal of 40 mL of CSF) can be repeated two or three times for consecutive days to improve the predictive value before shunting. Gait and balance often improve after shunt, more than cognition and bladder disorders. In the elderly population, the prognosis after 3 years is non conclusive despite initial improvement. Poor prognosis seems to be due to associated pathologies in particular neurodegenerative diseases. This should be considered in decision-making of CSF shunt.

Pulse wave velocity does not correlate to age in the upper limb but in the aorta and lower limb. We studied the link between ageing and pulse wave transit time (PWtt) indexes at the toe and finger.Measurements were performed in 300 patients in occupational medicine and primary care after 5minutes supine rest using the device studied (pOpmètre(®), Axelife SAS, France). It measures transit time between R-ECG and finger or toe pulse signal (ttf or ttt respectively). We define as follows three indexes: difference between transit times: Dtf=ttt-ttf; pulse wave velocity PWVft=k*subjects height/Dtf (m/s); and the pOpscore(®) as the ratio of toe PWV/fingerPWV.Of the 300 tested patients, 147 were analysed using univariate correlation: age (P10(-4)), SBP (P10(-4)), DBP (P0.02) and BMI (P0.04) correlated to Dtf, PWVtf and pOpscore(®). Using stepwise regression analysis with Age, BMI, SBP, DBP, MBP: Dtf was dependent with age (P10(-4)) and SBP (P0.01); PWVtf with age (P0.0001), SBP (P0.01) and DBP (P0.05); pOpscore(®) was dependent only to age (P10(-4)).In this study, in contrast with the other vascular indexes studied dependent to age and blood pressure, pOpscore(®) was dependent only to ageing. pOpmètre(®) is a promising technique for routine determination of arterial stiffness and pOpscore(®) appears to be appropriate to study the structural vascular ageing in outpatient.

The antihypertensive efficacy and acceptability of perindopril, an angiotensin-converting enzyme (ACE) inhibitor, was evaluated in 2,927 elderly (≥70 years) hypertensive patients in general practice, as part of an open 6-month trial conducted on a total of 23,460 patients with mild-to-moderate hypertension. Patients were ambulatory and selected if diastolic blood pressure (DBF) was between 94 and 115 mm Hg and no serious illness or ACE inhibitor intolerance was known. Perindopril was started at 2 or 4 mg once daily and, if supine DBP remained >90 mm Hg, the daily dose could be doubled after 1 or 3 months (or a diuretic added if perindopril titration reached 8 mg). At entry, the 2,927 patients (65% females) were on average 74 years old, body weight was 68.2 kg, duration of hypertension was 9.4 years, and prior antihypertensive treatment was present in 78%. Percentage of normal DBP (≤90 mm Hg) was 69% at 1 month, 86% at 3 months (in patients on perindopril alone), and 94% at 6 months. At 6 months the reduction of systolic blood pressure and DBP was 28 and 16.6 mm Hg, respectively. Of the 2,927 patients at entry, 8.6% dropped out during the trial, including 6.1% due to side effects. Cough was the most common symptom (8.9%) leading to withdrawal in 3.4% of cases. In one patient, serum creatinine increased (3-fold at 1 month), but overall no significant variation of renal function occurred, as shown by stable plasma creatinine and potassium levels.

The objective of this study was to systematically review all published articles examining the relationship between the occurrence of falls and changes in gait and attention-demanding task performance whilst dual tasking amongst older adults. An English and French Medline and Cochrane library search ranging from 1997 to 2008 indexed under 'accidental falls', 'aged OR aged, 80 and over', 'dual task', 'dual tasking', 'gait', 'walking', 'fall' and 'falling' was performed. Of 121 selected studies, fifteen met the selection criteria and were included in the final analysis. The fall rate ranged from 11.1% to 50.0% in retrospective studies and from 21.3% to 42.3% in prospective ones. Amongst the three retrospective and eight prospective studies, two and six studies, respectively, showed a significant relationship between changes in gait performance under dual task and history of falls. The predictive value for falling was particularly efficient amongst frail older adults compared with healthy subjects. Two prospective studies challenged the usefulness of the dual-task paradigm as a significant predictor compared to single task performance and three studies even reported that gait changes whilst dual tasking did not predict falls. The pooled odds ratio for falling was 5.3 (95% CI, 3.1-9.1) when subjects had changes in gait or attention-demanding task performance whilst dual tasking. Despite conflicting early reports, changes in performance whilst dual tasking were significantly associated with an increased risk for falling amongst older adults and frail older adults in particular. Description of health status, standardization of test methodology, increase of sample size and longer follow-up intervals will certainly improve the predictive value of dual-task-based fall risk assessment tests.

Measurement of urinary albumin excretion (UAE) may be done on a morning urinary sample or on a 24 hour-urine sample. Values defining microalbuminuria are: - 24-hour urine sample: 30-300 mg/24 hours - Morning urine sample: 20-200 mg/mL or 30-300 mg/g creatinine or 2.5-25 mg/mmol creatinine (men) or 3.5-35 mg/mol (women). - Timed urine sample: 20-200 mug/min. The optimal use of semi-quantitative urine test-strip is not clearly defined. It is generally believed that microalbuminuria reflects a generalized impairment of the endothelium; however, no definite proof has been shown in humans. In diabetic subjects, microalbuminuria is a marker of increased risk of cardiovascular (CV) and renal morbidity and mortality in type 1 and type 2 diabetic subjects. The increase in UAE during follow-up is also a marker of CV and renal risk in type 1 and type 2 diabetic subjects; its decrease during follow-up is associated with lower risks. In non-diabetic subjects, microalbuminuria is a marker of increased risk for diabetes mellitus, deterioration of the renal function, CV morbidity and all-cause mortality. It is a marker of increased risk for the development of hypertension in normotensive subjects, and is associated with unfavorable outcome in patients with cancer and lymphoma. Persistence or elevation of UAE overtime is associated with deleterious outcome in some hypertensive subjects. Measurement of UAE may be recommended in hypertensive subjects with 1 or 2 CV risk factors in whom CV risk remains difficult to assess, and in those with refractory hypertension: microalbuminuria indicates a high CV risk and must lead to strict control of arterial pressure. Studies focused on microalbuminuria in non-diabetic, non-hypertensive subjects are limited; most of them suggest that microalbuminuria predicts CV complications and deleterious outcome as it is in diabetic or hypertensive subjects. Subjects with a history of CV or cerebrovascular disease have an even greater CV risk if microalbuminuria is present than if it is not; however, in all cases, therapeutic intervention must be aggressive regardless of whether microalbuminuria is present or not. It is not recommended to measure UAE in non-diabetic non-hypertensive subjects in the absence of history of renal disease. Monitoring of renal function (UAE, serum creatinine and estimation of GFR) is annually recommended in all subjects with microalbuminuria.in patients with microalbuminuria, weight reduction, sodium restriction (6 g/day), smoking cessation, strict glucose control in diabetic subjects, strict arterial pressure control are necessary; in diabetic subjects: use of maximal doses of ACEI or ARB are recommended; ACEI/ARB and thiazides have synergistic actions on arterial pressure and reduction of UAE; in non-diabetic subjects, any of the five classes of anti-hypertensive medications (ACEI, ARB, thiazides, calcium channel blockers or beta-blockers) can be used.

malnutrition is highly prevalent in diseased elderly people, especially in hospital departments, and weight loss also occurs during hospital stays. Among the tools proposed to define malnutrition and to screen persons at risk of malnutrition, the nutritional risk score (NRS) has been suggested as a simple tool.the aim of the present study was to test the validity of the NRS to predict weight changes 3 months after discharge. NRS and visual analogue scales for hunger, early satiety, thirst, fatigue and pain were performed in 106 patients aged 65 yrs and over, 67 treated for cancer, without overt malnutrition.forty six patients lost more than 1 kg. None of the parameters tested was correlated with weight changes, except NRS which was weakly correlated (r=-0.22, P=0.037). However a 0 score at NRS was associated with weight changes ranging -9 to +5 kg. Furthermore, the 11 patients with a high NRS score and weight loss were in a clinical situation that made it very likely that they would lose weight. In conclusion, NRS is not a valid score to predict weight change.

Urinary albumin excretion (UAE) may be assayed on a morning urinary sample or a 24 h-urine sample. Values defining microalbuminuria are: 1) 24-h urine sample: 30-300 mg/24 h; 2) morning urine sample: 20-200 mg/ml or 30-300 mg/g creatinine or 2.5-25 mg/mmol creatinine (men) or 3.5-35 mg/mmol (women); 3) timed urine sample: 20-200 mug/min. The optimal use of semi-quantitative urine test-strip is not clearly defined. It is generally believed that microalbuminuria reflects a generalized impairment of the endothelium; however, no definite proof has been obtained in humans.Microalbuminuria is a marker of increased risk of cardiovascular (CV) and renal morbidity and mortality in type 1 and type 2 diabetic subjects. The increase in UAE during follow-up is associated with greater CV and renal risks in type 1 and type 2 diabetic subjects; its decrease during follow-up is associated with lower risks. IN NON-DIABETIC SUBJECTS: Microalbuminuria is a marker of increased risk for diabetes mellitus, deterioration of renal function, CV morbidity and all-cause mortality. It is a marker of increased risk for the development of hypertension in normotensive subjects, and is associated with unfavorable outcome in patients with cancer and lymphoma. Persistence of elevated UAE during follow-up is associated with poor outcome in some hypertensive subjects. Measurement of UAE may be recommended in hypertensive medium-risk subjects with 1 or 2 CV risk factors in whom CV risk remains difficult to assess, and in those with refractory hypertension: microalbuminuria indicates a high CV risk and must lead to strict control of arterial pressure. Studies focused on microalbuminuria in non-diabetic non-hypertensive subjects are limited; most of them suggest that microalbuminuria predicts CV complications and deleterious outcome. Subjects with a history of CV or cerebrovascular disease have an even greater CV risk if microalbuminuria is present than if it is not; however, in all cases, therapeutic intervention must be aggressive regardless of whether microalbuminuria is present or not.

Executive dysfunction is regularly reported in patients with Alzheimer's disease. Nevertheless few studies have focused on planning ability in this neurodegenerative disease.This study aimed to investigate the formulation and the execution of plans in Alzheimer's disease using an ecological planning subtask derived from the Behavioural Assessment of the Dysexecutive Syndrome test battery, the "Zoo Map Test". There are two trials. The first trial consists of a "high demand" version of the subtask in which the subjects must plan in advance the order in which they will visit designated locations in a zoo (formulation level). In the second, or "low demand" version, the subject is simply required to follow a concrete externally imposed strategy to reach the locations to visit (execution level). The test was given to 16 patients with Alzheimer's disease and 13 normal elderly subjects.The two way ANOVAs mainly showed more difficulties in patients with Alzheimer's disease than in healthy elderly in both conditions. The difference between formulation and execution was greater in patients with Alzheimer's disease than in healthy elderly. Planning impairments mainly correlated with behavioural changes (in particular motivational changes) observed by patient's relatives.These results suggest that patients with Alzheimer's disease have some problems to mentally develop logical strategies and to execute complex predetermined plans, which are partially related to behavioural changes.

Hypercalcaemia occurs in less than 15% of lymphomas but is associated with a poor prognosis. A patient known to have a testicular lymphoma was admitted because of asthenia and weight loss. Hypercalcemia and high serum level of calcitriol were found. A high-grade lymphoma attesting a Richter's syndrome was diagnosed. Palliative treatment consisting in corticosteroids and pamidronate was instituted. Hypercalcaemia in lymphoma has a poor prognosis and is often attributed to an acquired uncontrolled vitamin D 1-alpha-hydroxylase activity by the macrophages close to the lymphomatous cells. Influences of TNFalpha, interleukine 6 and PTHrp are also reported.

But La rigidite arterielle (RA) est un facteur predictif independant de risque cardiovasculaire. Elle peut etre estimee facilement par une nouvelle technique : pOpmetre ® (Axelife SAS, France). La mesure est realisee avec le rendu de l’examen en moins de 2 minutes. Des donnees de la litterature suggerent une augmentation de la rigidite arterielle chez les patients SAPL. Nous avons etudie le lien entre les indices pOpmetre ® , l’epaisseur intima-media carotidienne et la rigidite arterielle mesuree par echographie Doppler, ainsi que la relation avec les taux d’anticorps anti-phospholipides et l’âge chez des patients avec un SAPL primaire par rapport a des temoins ayant presente une thrombose veineuse profonde. Methodes La rigidite arterielle carotidienne et l’epaisseur intima-media (EIM) ont ete determinees par echo-Doppler chez 20 patients SAPL et 20 temoins ayant presente une thrombose veineuse distale profonde. Chez tous les participants, la RA aortique a ete evaluee par impedance-metre (Physioflow ® ESAOTE, Italie) et la VOPdo par pOpmetre ® , qui calcule la vitesse de l’onde de pouls (VOPdo), la difference des temps de transit (Dod), et un indice de velocite. La pression arterielle et l’indice de pression systolique (IPS) ont ete mesures. Les titres d’anticorps aPL ont ete colliges chez les patients. Resultats Les deux groupes etaient comparables pour la pression arterielle brachiale et l’IPS (1,15 ± 0,04 versus 1,12 ± 0,03 ; ns), ainsi que pour la moyenne d’âge. Le groupe SAPL avait une EIM superieure (0,59 ± 0,02 versus 0,53 ± 0,01 mm, p p ® (VOPdo [13,2 ± 0,9 versus 10,5 ± 0,6 m/s, p p p r 2 = 0,1, p = 0,002), RA ( r 2 = 0,11, p = 0,002), pOpmetre ® VOPdo ( r 2 = 0,23, p r 2 = 0,16, p = 0,0003), pas avec l’IPS ( r 2 = 0,03, p = 0,06). Aucune correlation a l’âge et aux titres d’aPL n’etait retrouvee. Conclusion Chez des patients SAPL, la RA mesuree par pOpmetre ® est augmentee par rapport aux temoins et est correlee a la rigidite arterielle et a l’EIM mesurees en echographie Doppler.

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.

Moderate hyperhomocysteinemia is a risk factor for deep venous thrombosis. The homozygous C677T methylenetetrahydrofolate reductase (MTHFR) mutation is associated with increased level of total plasma homocysteine. The association between homozygous C677T mutation and deep venous thrombosis is still controversial.In order to evaluate this association, we studied the prevalence of C677T mutation in 168 patients with confirmed deep venous thrombosis; 31 with an idiopathic deep venous thrombosis (group A) and 137 with thromboembolic event explained by one or more clinical and/or biological risk factors (group B).The distribution of genotypes was different between group A and B [++/+ -/- -(n(%))] : 9(29)/10(32)/12(39) vs 16(12)/57(42)/64(46) (chi(2) : 6.03; P: 0.049). The comparison between homozygotes and the two other genotypes showed significant statistical relationship between homozygous genotype and idiopathic character of deep venous thrombosis (chi(2) : 6.01; P : 0.014; OR : 3.09 [IC 95% : 1.06-8.53]).These results suggest that homozygous C677T methylenetetrahydrofolate reductase mutation could be considered as a genetic risk factor for venous thrombosis.

Arterial or venous thromboses are frequent in patients with homocystinuria. Because severe homocystinuria is rare, prevalence of thrombosis, especially in France, is still unknown.Review of the clinical outcome of 37 patients with homocystinuria due to cystathionine-cystathionine beta-synthase deficiency (34) and 5,10-methylenetetrahydrofolate reductase (three) lead us to describe vascular complications occurring in 12 (32%) of them.Venous thromboembolism is the earlier and the most frequent one and is mainly found in untreated late-diagnosed cases. Under specific treatment of homocystinuria, thromboses are rare and always a complication of surgery associated with high thromboembolic risk. Association with factor V Leiden increased the risk of venous thrombosis.
