[Percutaneous aortic valve replacement: outcome of patients evaluated by EMG at Toulouse University Hospital preprocedure]. / Remplacement valvulaire aortique par voie percutanée : devenir des patients évalués par l'EMG au CHU de Toulouse en préprocédure.

Transcatheter Aortic Valve Implantation has become the preferred method of aortic valve replacement in the elderly. Preoperative standardized geriatric assessment (SGA) helps guide the decision to proceed, taking into account geriatric parameters not targeted by surgical risk scores. This is a descriptive, retrospective study of patients who underwent EGS at the Toulouse University Hospital, analyzing their length of stay and postoperative care pathway.

Potential determinants of unfavourable healthcare utilisation trajectories during the last year of life of people with incident Alzheimer Disease or Related Syndromes: a nationwide cohort study using administrative data.

BACKGROUND: people approaching the end-of-life frequently face inappropriate care. With Alzheimer Disease or Related Syndromes (ADRS), end-of-life is characterised by progressive decline, but this period remains difficult to identify. This leads to a lack of anticipation and sometimes with unfavourable healthcare utilisation trajectories (HUTs). OBJECTIVE: to quantify unfavourable HUTs during the last year of life and identify their potential determinants in both community and nursing-home settings. DESIGN: nationwide cohort study using administrative database. SETTING: French community and nursing-home residents. SUBJECTS: incident ADRS people identified in 2012, who died up to 31 December 2017. METHODS: we used multidimensional clustering to identify 15 clusters of HUTs, using 11 longitudinal healthcare dimensions during the last year of life. Clusters were qualitatively assessed by pluri-disciplinary experts as favourable or unfavourable HUTs. Individual and contextual potential determinants of unfavourable HUTs were studied by setting using logistic random-effect regression models. RESULTS: 62,243 individuals died before 31 December 2017; 46.8% faced unfavourable end-of-life HUTs: 55.2% in the community and 31.8% in nursing-homes. Individual potential determinants were identified: younger age, male gender, ADRS identification through hospitalisation, shorter survival, life-limiting comorbidities, psychiatric disorders, acute hospitalisations and polypharmacy. In the community, deprivation and autonomy were identified as potential determinants. Contextual potential determinants raised mostly in the community, such as low nurse or physiotherapist accessibilities. CONCLUSIONS: Nearly half of people with ADRS faced unfavourable HUTs during their last year of life. Individual potential determinants should help anticipate advance care planning and palliative care needs assessment. Contextual potential determinants suggest geographical disparities and health inequalities.

Impact of a personalised care plan for the elderly calling emergency medical services after a fall at home: The RISING-DOM multi-centre randomised controlled trial protocol.

BACKGROUND: A growing number of emergency calls are made each year for elderly people who fall. Many of them are not taken to hospital or are rapidly discharged from the Emergency Department (ED). Evidence shows that, with no further support, this vulnerable population is particularly at risk of injuries, dependency and death. This study aims to determine the effectiveness of a comprehensive geriatric assessment and a tailored intervention in the elderly calling on an Emergency Medical Service (EMS) for a fall at home, but not conveyed to the ED or rapidly discharged from it (less than 24 h from hospitalisation), to the time to institutionalisation or death. METHODS: Rising-Dom is a two-arm randomised (ratio 1:1), interventional, multi-centre and open study. Community-dwelling elderly people (≥ 70 years) who call an EMS for a fall at home are recruited. The intervention group receives home visits by a nurse with a comprehensive fall risk assessment and a personalised intervention care plan with a planned follow-up (six nurse home visits and five nurse phone calls). Subjects enrolled in the usual care-control group continue to receive their routine care for the prevention or treatment of diseases. Primary (time to institutionalisation or death) and secondary (unscheduled hospitalisations, additional EMS calls relating to falls, functional decline and quality of life) outcome data will be collected for both groups through five phone calls made by Clinical Research Associates (CRA) blind to the participants' group during the follow-up period (24-months). Twelve hospital centres in the South-West of France are participating in the study as study sites. The inclusion period started in October 2019 and will end in March 2022. By the end of this period, 1,190 subjects are expected to be enrolled. DISCUSSION: Studies on elderly home falls have rarely concerned people who were not taken to hospital. The Rising-Dom intervention scheme should enhance understanding of features related to this vulnerable population and investigate the impact of a nurse care at home on delaying death and institutionalisation.

[Content and application of Icope step 2: feedback from nurses]. / Contenu et application du step 2 d'Icope, retour d'expérience des infirmières.

With the ICOPE programme, the nurses received specific, theoretical and practical, training, that enabled them to broaden their field of competence. This approach has enabled them to expand and consolidate professional cooperation networks and to consolidate their, crucial, position in prevention in the broad sense of the term with the elderly. The aim of the Icope programme is to offer long-term monitoring of the senior citizen, as part of his or her life project.

Health workers perception on telemedicine in management of neuropsychiatric symptoms in long-term care facilities: Two years follow-up.

The management of neuropsychiatric symptoms is a challenge in long-term care facilities. Our objective was to assess the perception of telemedicine, as a useful tool to connect staff to specialized units. In this multicenter prospective study, 90 patients from ten facilities benefited from 180 sessions over two years. The primary outcome was the perception of telemedicine evaluated through semi-structured interviews at baseline and two years later. Our results revealed positive perceptions of telemedicine, confirmed after two years of real-life experience with its use. Not only do staff members believe that telemedicine is not a downgraded version of medicine, but they also believe that it could improve the quality of care. They expressed a very positive sense of recognition of their professional qualifications and indicated their need to be involved in change processes to ensure successful implementation and better adherence to telemedicine as a service.

Potentially modifiable factors associated with agitation and aggression in Alzheimer's disease: results of the ICTUS study.

OBJECTIVES: To study potentially modifiable factors associated with the severity of agitation or aggression (A/A) symptoms among Alzheimer's disease (AD) patients. DESIGN: Data from the Impact of Cholinergic Treatment Use (ICTUS) study, European longitudinal prospective observational study. SETTING: Community dwelling outpatients included in 29 European memory clinics. PARTICIPANTS: 1375 participants with probable AD (Mini-Mental State Examination score of 10-26) with an informal caregiver. MEASUREMENTS: At baseline and twice yearly over the two-year follow-up, patients underwent comprehensive clinical and neuropsychological assessments: sociodemographic data, cognitive status, functional impairment, and assessment of neuropsychiatric symptoms based on Neuro-Psychiatric Inventory (NPI). The ZARIT scale assessed the caregiver's burden. The variable of interest was the severity of the item of A/A of the NPI. To study factors associated to the severity of A/A symptoms six months later, a multivariate mixed regression model was used. RESULTS: Frequency of A/A symptom varied from 30% to 34% at each visit. Two factors were found to be independently associated with the severity of A/A: (1) the presence of affective disorder (anxiety, depression, and/or irritability) that increased the severity of the A/A by 0.89 point (coefficient:0.89; 95% Confidence Interval (CI) = [0.48,1.30], p < 0.001), and (2) a severe caregiver burden that increased the severity of the A/A by 1.08 point (coefficient:1.08; 95% CI = [0.69,1.47], p < 0.001). CONCLUSION: Research should evaluate whether the identification and treatment of an affective disorder along with the evaluation and optimal management of the caregiver would have a positive impact on the course of A/A in mild to moderate AD patients.

Distinct effect of age, sex, and CMV seropositivity on dendritic cells and monocytes in human blood.

We analyzed the impact of age, sex, and CMV on blood monocyte and dendritic cell (DC) subpopulations in 256 healthy individuals aged from 19 to 96 years. Flow cytometry was performed on whole blood within the 4 h following blood drawing. Myeloid (mDC) and plasmacytoid DC (pDC), classical, intermediate, and nonclassical monocytes were enumerated by means of TruCount tubes (BD Biosciences). We provided reference values for mDC, pDC and the three monocyte subpopulations. The numbers of classical, intermediate, and nonclassical monocytes slightly increased with age while the numbers of mDC and pDC did not vary significantly. The level of expression of CD64 and CD163 on monocytes significantly increased with age while HLA-DR expression did not vary significantly. More precisely, CD163 expression level on intermediate monocyte slightly increased with age in women only (Spearman P = 0.019) while CD64 expression increased on monocytes in CMV-positive individuals only. We observed that sex had almost no impact on the numbers of monocytes and DC and on their expression level of CD64 and HLA-DR. We observed a significant decrease in the numbers of pDC with age in CMV-positive individuals, but not in CMV negative individuals. This suggests that the lifelong subclinical infection by CMV could influence the number of circulating DC of lymphoid origin. In contrast, CMV serostatus had no significant impact on absolute numbers of mDC and monocytes.

Group and individual cognitive therapies in Alzheimer's disease: the ETNA3 randomized trial.

BACKGROUND: Although non-drug interventions are widely used in patients with Alzheimer's disease, few large scale randomized trials involving a long-term intervention and several cognitive-oriented approaches have been carried out. ETNA3 trial compares the effect of cognitive training, reminiscence therapy, and an individualized cognitive rehabilitation program in Alzheimer's disease to usual care. METHODS: This is a multicenter (40 French clinical sites) randomized, parallel-group trial, with a two-year follow-up comparing groups receiving standardized programs of cognitive training (group sessions), reminiscence therapy (group sessions), individualized cognitive rehabilitation program (individual sessions), and usual care (reference group). Six hundred fifty-three outpatients with Alzheimer's disease were recruited. The primary efficacy outcome was the rate of survival without moderately severe to severe dementia at two years. Secondary outcomes were cognitive impairment, functional disability, behavioral disturbance, apathy, quality of life, depression, caregiver's burden, and resource utilization. RESULTS: No impact on the primary efficacy measure was evidenced. For the two group interventions (i.e. cognitive training and reminiscence), none of the secondary outcomes differed from usual care. The larger effect was seen with individualized cognitive rehabilitation in which significantly lower functional disability and a six-month delay in institutionalization at two years were evidenced. CONCLUSIONS: These findings challenge current management practices of Alzheimer's patients. While cognitive-oriented group therapies have gained popularity, this trial does not show improvement for the patients. The individualized cognitive rehabilitation intervention provided clinically significant results. Individual interventions should be considered to delay institutionalization in Alzheimer's disease.

Assessing Alzheimer's disease patients' quality of life: Discrepancies between patient and caregiver perspectives.

INTRODUCTION: Quality of life (QOL) is an important dimension to consider in Alzheimer's disease (AD), but few large-scale studies have analyzed self and caregiver reports of patient QOL. METHODS: Patient QOL was evaluated in a cohort of 574 AD patients with the QOL-AD scale over 2 years. RESULTS: Caregiver reports of patient QOL were lower at baseline than self reports. Older patient age was associated with overestimation of QOL by caregivers, whereas neuropsychiatric inventory score and caregiver burden were associated with underestimation. Activities of daily living limitation, depressive symptoms, and caregiver burden were systematically associated with poorer QOL, whereas caregiver relationship and apathy were associated with poorer QOL only for self reports or caregiver reports, respectively. Cognitive function and professional care were not associated with QOL. Self-rated patient QOL did not change over time, whereas disease severity markers and caregiver-rated patient QOL declined. DISCUSSION: It is important to assess both self and caregiver ratings when assessing patient QOL.

[Identifying frailty and delaying dependency]. / Repérer la fragilité et retarder l'entrée dans la dependence.

As a person ages, frailty and chronic pathologies appear which can restrict their level of activity and gradually lead to dependency. Identifying and treating this frailty in people aged 65 and over is therefore essential for improving and/or maintaining their quality of life.

Medication development for agitation and aggression in Alzheimer disease: review and discussion of recent randomized clinical trial design.

ABSTRACT Background: The management of disruptive neuropsychiatric symptom (NPS) such as agitation and aggression (A/A) is a major priority in caring for people with Alzheimer's disease (AD). Few effective pharmacological or non-pharmacological options are available. Results of randomized clinical trials (RCTs) of drugs for A/A have been disappointing. This may result from the absence of biological efficacy for medications tested in treating A/A. It may also be related to methodological issues such as the choice of outcomes. The aim of this review was to highlight key methodological issues pertaining to RCTs of current and emerging medications for the treatment of A/A in AD. Methods: We searched PubMed/Medline, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov for RCTs comparing medications with either placebo or other drugs in the treatment of A/A in AD, between January 2008 and December 2013. Results: We identified a total of 18 RCTs; of these, 11 were completed and 7 ongoing. Of the ongoing RCTs, only one is in Phase III. Seven of 10 completed RCTs with reported results did not report greater benefit from drug than placebo. Each of the completed RCTs used a different definition of "clinically significant A/A." There was considerable heterogeneity in study design. The primary endpoints were largely proxy-based but a variety of scales were used. The definition of caregiver and scales used to assess caregiver outcomes were similarly heterogeneous. Placebo response was notable in all trials. Conclusions: This review highlights a great heterogeneity in RCTs design of drugs for A/A in AD and some key methodological issues such as definition of A/A, choice of outcome measures and caregiver participation that could be addressed by an expert consensus to optimize future trials design.

A follow-up intervention in severely demented patients after discharge from a special Alzheimer acute care unit: impact on early emergency room re-hospitalization rate.

BACKGROUND: Emergency room (ER) re-hospitalizations are prevalent in severe Alzheimer's disease affected older patients. DESIGN: Quasi-experimental before and after study. SETTING: Discharge of severely demented patients from a Special Alzheimer Acute Care Unit. PARTICIPANTS: A total of 390 patients hospitalized in the unit from 2007 through 2009, with at least one of the following characteristics: severe disruptive behavioral and psychological symptoms of dementia (BPSD) (agitation, aggressiveness, and psychotic symptoms), change of living arrangement related to BPSD, exhaustion of the principal caregiver, and discharge of a subject with anosognosia living alone in the community. INTERVENTION: The intervention consisted of an individualized care plan, targeting the problems observed during the hospital stay, implemented by the means of regular telephone contacts (in the first week after discharge, before the end of the first month, and then at 3 and 6 months) between a geriatric team and the patient's caregiver. Information was gathered on functional decline, BPSD, change of living arrangement and treatment. The calls were followed by a telephone intervention providing advice, support, and information to the caregiver. When required, these calls were followed by a consultation with a physician or psychologist, or by a consultation in the patient's home. MEASUREMENTS: The primary outcome measure was the ER re-hospitalization rate, defined as occurring within 31 days of discharge. RESULTS: The early ER re-hospitalization rate was 8.39% in 2007 versus 8.02% in 2008 (p = 0.818) and 7.47% in 2009 (p = 0.563). Vocal disruptive behavior are more prevalent in re-hospitalized patients (9.64% versus 3.97%, p = 0.05) than in non re-hospitalized patients. CONCLUSION: We found a nonsignificant decrease of early ER re-hospitalization rate at 1 month after discharge. Interventions addressing severe dementia affected patients with BPSD are needed, as this is a major issue in the organization of health care systems.

Adverse drug reactions in patients with Alzheimer's disease and related dementia in France: a national multicentre cross-sectional study.

PURPOSE: To assess the prevalence of adverse drug reactions (ADRs) occurring in patients with Alzheimer's disease (AD) or other dementia in France. METHODS: A cross-sectional multicentre study was conducted by the French network of the 31 regional pharmacovigilance centres on a given day. The subjects were selected by random draw to be a representative sample of French patients with dementia: consultations of dementia clinics, nursing-homes, acute and long care geriatric units, rehabilitation care geriatric units. The staff of each medical structure together with that of the pharmacovigilance centre defined a day for including the patients. Socio-demographic data, history, ADR and drugs given were registered. RESULTS: There were 1332 subjects included, 51.1% living at home, 48.8% in institutions, aged 82.0 ± 8.0 years (46-108); 61.3% suffered from AD. Mean number of drugs was 6.3 ± 3.1. Anti-dementia drugs were given to 66.4% subjects. ADR prevalence was 5.0% (95% CI: 3.9-6.2) without a significant difference between at home and institutionalized patients. ADR consisted of gastro-intestinal (23.2%), central nervous system (17.4%) and psychiatric disorders (8.7%). Of the ADR, 31.9% were serious, and 47.8% preventable. The drugs most often involved were anti-dementia (28.9%), cardio-vascular (28.9%) and psychotropic drugs (26.4%, anxiolytics, hypnotics, antidepressants, neuroleptics). CONCLUSION: This national scale study showed that iatrogenesis in patients with AD and related dementia can at times be serious and preventable. Therefore, special attention is required when prescribing psychotropic and anti-dementia drugs, as they are frequently used and induce half of the ADR in this population.

Sarcopenia and cognitive impairment in elderly women: results from the EPIDOS cohort.

BACKGROUND: common pathophysiological pathways are shared between age-related body composition changes and cognitive impairment. OBJECTIVE: evaluate whether current operative sarcopenia definitions are associated with cognition in community-dwelling older women. DESIGN: cross-sectional analyses. SUBJECTS: a total of 3,025 women aged 75 years and older. MEASUREMENTS: body composition (assessed by dual energy X-ray absorptiometry) and cognition (measured by short portable mental status questionnaire) were obtained in all participants. Multivariate logistic regression models assessed the association of six operative definitions of sarcopenia with cognitive impairment. Gait speed (GS, measured over a 6-meter track at usual pace) and handgrip strength (HG, measured by a hand-held dynamometer) were considered additional factors of interest. RESULTS: a total of 492 (16.3%) women were cognitively impaired. The prevalence of sarcopenia ranged from 3.3 to 18.8%. No sarcopenia definition was associated with cognitive impairment after controlling for potential confounders. To proof consistency, the analyses were performed using GS and HG, two well-established predictors of cognitive impairment. Low GS [odds ratio (OR) 2.42, 95% confidence interval (CI) 1.72-3.40] and low HG (OR: 1.81, 95% CI: 1.33-2.46) were associated with cognitive impairment. CONCLUSION: no significant association was evidenced between different operative sarcopenia definitions and cognitive impairment. The study suggests that the association between physical performance and cognitive impairment in not mediated by sarcopenia.

Exploring Population Characteristics and Recruitment Challenges in Older People Experiencing Falls at Home without Hospitalization or with an Emergency Department Visit: Insights from the RISING-DOM Experience.

Background: An increasing number of falls among community-living older adults are reported in emergency calls. Data on evidence of appropriate fall prevention interventions are limited and challenges in recruiting this population in randomized trials are acknowledged. Purpose: The main aim of this study was to provide demographic data, circumstance and fall-related outcomes of the population in the RISING-DOM study [Impact d'une évaluation des facteurs de RISque de chute et d'une prise en charge personnalisée, sur la mortalité et l'institutionnalisation, après INtervention du SAMU chez la personne âGée à DOMicile], a multicenter, randomized interventional trial involving community-dwelling older adults who have experienced a fall at home and were not hospitalized. Additionally, the challenges of remote recruitment in this population were discussed. Patients and Methods: Participants were identified through the Occitania Emergency Observatory database. Participant recruitment and data collection were performed through telephone interviews (October 2019-March 2022). Additionally, a sample survey of Emergency Medical Services calls was carried out. Results: Out of the 1151 individuals screened, a total of 951 participants were included in the trial follow-up, resulting in an acceptance rate of 82.62%. The screening delay was extended due to the COVID-19 pandemic. Recruiting difficulties were mainly related to identifying potential participants, unavailable contact information and unreachability. Participants' mean age was 84.1 years, 65.8% were women, and 44.3% lived alone. Pain was the most frequent outcome (53%). In the previous year, 73.5% of participants reported experiencing a fall, with 66.7% of those falls requiring assistance from Emergency Medical Services (EMS). Nearly, 40% did not take proactive steps to prevent future falls and walking aids (79.8%) were the most common preventive action. Conclusion: Indicators of a high-risk group of falls have been identified underscoring the need for appropriate fall interventions in the target population. Challenges of large sampling for randomized fall prevention trials were provided. Trial Registration: Clinicaltrials.gov identifier: NCT04132544. Registration date: 18/10/2019. https://www.clinicaltrials.gov/ct2/show/NCT04132544?term=rising-dom&draw=2&rank=1.

Frailty in Older Patients with Transthyretin Cardiac Amyloidosis.

Background-Transthyretin cardiac amyloidosis (ATTR-CA) prevalence increases with age. The interplay between frailty and heart failure has been increasingly recognized. The objective of this study is to compare clinical, biological, and transthoracic echocardiography (TTE) characteristics of older ATTR-CA patients according to the G8 frailty screening tool. Methods-Patients over 75 years old with a confirmed diagnosis of ATTR-CA were included between January 2020 and April 2021. All patients underwent a routine blood test, TTE, and a functional assessment with a six-minute walking distance test (6MWD) or cardiopulmonary exercise testing (CPET), and the G8 score was calculated. Results-Fifty-two patients were included. Thirty-nine (75%) patients were frail and their mean NYHA stage was more severe (2.2 vs. 1.7; p = 0.004); 62% of them had a Gilmore stage of 2 or 3 (p = 0.05). Global left ventricular strain (GLS) was lower (-11.7% vs. -14.9%; p = 0.014) and the interventricular septum was thicker (18 ± 2 mm vs. 17 ± 2 mm; p = 0.033) in frail patients. There were no significant differences according to functional tests. Conclusion-The majority of older patients with ATTR-CA are frail according to the G8 score. They are more symptomatic and have an increased cardiac involvement and a poorer prognosis, requiring more personalized cardiac management.

Monocytes are the main source of STING-mediated IFN-α production.

BACKGROUND: Type I interferon (IFN-I) production by plasmacytoid dendritic cells (pDCs) occurs during viral infection, in response to Toll-like receptor 7 (TLR7) stimulation and is more vigorous in females than in males. Whether this sex bias persists in ageing people is currently unknown. In this study, we investigated the effect of sex and aging on IFN-α production induced by PRR agonist ligands. METHODS: In a large cohort of individuals from 19 to 97 years old, we measured the production of IFN-α and inflammatory cytokines in whole-blood upon stimulation with either R-848, ODN M362 CpG-C, or cGAMP, which activate the TLR7/8, TLR9 or STING pathways, respectively. We further characterized the cellular sources of IFN-α. FINDINGS: We observed a female predominance in IFN-α production by pDCs in response to TLR7 or TLR9 ligands. The higher TLR7-driven IFN-α production in females was robustly maintained across ages, including the elderly. The sex-bias in TLR9-driven interferon production was lost after age 60, which correlated with the decline in circulating pDCs. By contrast, STING-driven IFN-α production was similar in both sexes, preserved with aging, and correlated with circulating monocyte numbers. Indeed, monocytes were the primary cellular source of IFN-α in response to cGAMP. INTERPRETATION: We show that the sex bias in the TLR7-induced IFN-I production is strongly maintained through ages, and identify monocytes as the main source of IFN-I production via STING pathway. FUNDING: This work was supported by grants from Région Occitanie/Pyrénées-Méditerranée (#12052910, Inspire Program #1901175), University Paul Sabatier, and the European Regional Development Fund (MP0022856).

Associated factors with antipsychotic use in assisted living facilities: a cross-sectional study of 4367 residents.

BACKGROUND: antipsychotics are widely used in assisted living (AL facilities). Even more, the prescription of these drugs is gradually increasing since the availability of second-generation atypical antipsychotics. More knowledge is needed on prescription reasons to understand this increasing prevalence. METHODS: cross-sectional analysis of 4,367 residents. Data were obtained from medical records assessed by geriatricians from the AL facility. A multiple logistic regression model (backward stepwise) was used to assess the independent associated factors with antipsychotic use. RESULTS: antipsychotic prescription was found in 1,203 (27.5%) of 4,367 residents. The independent associated factors with the use of antipsychotics were the presence of a psychiatric disorder [odds ratio, OR = 5.30 (4.42-6.35)], the age under 80 years [OR = 2.08 (1.62-2.68)], admission from another institution [OR = 1.49 (1.12-1.98)], treated dementia [OR = 1.84 (1.47-2.30)], the presence of neuropsychiatric symptoms (NPS): verbal outbursts [OR = 2.58 (1.96-3.39)], threatening behaviours or physical violence [OR = 2.13 (1.71-2.65)], and aimless wandering [OR = 1.55 (1.17-2.04)], the presence of cardiovascular disease [OR = 0.79 (0.65-0.96)] and the presence of cerebrovascular disease [OR = 0.77 (0.64-0.92)]. CONCLUSIONS: the study found that more than a quarter of the residents received antipsychotics. This study also highlighted the independent associated factors with antipsychotic prescription showing 'off-label' prescriptions in conditions such as dementia and certain NPS. The study findings suggest that improvements in the management of dementia and NPS in AL facilities are needed. Non-pharmacological alternatives should be enhanced and further developed viewing the high prevalence of antipsychotic prescription.

Long-term progression of Alzheimer's disease in patients under antidementia drugs.

BACKGROUND: Patients with Alzheimer's disease (AD), even in the presence of symptomatic relief from medical intervention, face a persistent worsening of cognitive decline and performance in activities of daily living. Data regarding the long-term disease progression outside of therapeutic trials are lacking. We examined the effects of standard of care for AD patients on the prognosis of the disease in a real-life study over a 4-year period. METHODS: A total of 686 patients with mild-moderate AD were enrolled in 16 memory clinics (REseau sur la maladie d' Alzheimer FRançais [REAL.FR] cohort) and followed up twice annually with tools used in therapeutic trials (Mini-Mental Status Examination, Alzheimer Disease Assessment Scale-cognitive subscale [ADAS-cog]: cognitive function, Clinical Dementia Rating: dementia severity, Activity of Daily Living [ADL]: incapacities, NeuroPsychiatric Inventory: neuropsychiatric symptom). RESULTS: More than 90% of the patients used AD-specific medication over 4 years. Patients lost on average 2.4 points per year on the Mini-Mental Status Examination and gained 4.5 points on the ADAS-cog. ADL and NeuroPsychiatric Inventory scores became significantly worse over time. Incidence of incapacities for ADL and worsening of neuropsychiatric symptoms were 52.5 (95% confidence interval [CI]: 47.7-57.4) and 51.1 (95% CI: 46.2-56.1), respectively. Rates of mortality and institutionalization were 7.4 (95% CI: 6.2-8.5) and 13.4 (95% CI: 11.7-15.1). In all, 17% of patients in mild stage at baseline (Clinical Dementia Rating = 0.5) did not experience a major event (functional disabilities, neuropsychiatric symptoms, or death) over a 4-year period. CONCLUSIONS: As compared with previous surveys, the current study shows slower rates of decline in AD patients. The present data also underline the high level of variability of disease progression among AD patients. Outcome measures commonly used in clinical trials will need to take into account the recent changes in the prognosis of the disease.

[Specific care plan in different stages of Alzheimer's disease]. / Spécificités du plan d'aide et de soins aux différents stades des maladies d'Alzheimer.

The management and follow-up of patients with Alzheimers disease have stage-specific characteristics. In the mild stage, the key challenges are above all to improve the early diagnosis and the communication of the diagnosis. With the patient's agreement, a follow-up should be scheduled to assess, at each stage of the disease, cognitive and functional decline, and detect psycho-behavioral, nutritional or mobility complications. In the moderate or severe stages, prevention and treatment of caregiver burnout should be included in the follow-up. Finally, in the very severe stage, end of life and ethical issues should be considered. The followup and the intervention plan should be adapted to each patient, and require coordination between health care professionals and social workers. However, the practical aspects of the follow-up and the ways in which those can be improved are yet to be defined.
