Role of geriatric intervention in the treatment of older patients with cancer: rationale and design of a phase III multicenter trial.

BACKGROUND: In the general geriatric population, programs linking geriatric evaluation with interventions are effective for improving functional status and survival of the patients. Whether or not these interventions improve health related quality of life (HRQoL) or overall survival (OS) in older patients with cancer is not yet clear. Indeed, randomized data on the effect of such interventions on survival and HRQoL are rare and conflicting. We describe the rationale and design of a phase III multicenter trial aimed at assessing the efficacy of geriatric intervention in the management of elderly patients with cancer. METHODS/DESIGN: Approximately 1200 patients, 70 years and older, considered in need of a geriatric intervention based on the G8 screening tool will be randomized into two intervention arms. The 'Usual-care' arm involves standard oncological care based on pre-defined oncological protocols. In addition to the standard oncological care, the 'Case-management' arm involves a multidimensional geriatric assessment and interventions tailored for the patient. Efficacy will be assessed using a co-primary endpoint encompassing OS and HRQoL. DISCUSSION: This trial has been designed to assess whether focused geriatric case management can either improve OS or HRQoL in elderly cancer patients considered in need of geriatric assessment.

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.

Health and aging in elderly farmers: the AMI cohort.

BACKGROUND: The health of the agricultural population has been previously explored, particularly in relation to the farming exposures and among professionally active individuals. However, few studies specifically focused on health and aging among elders retired from agriculture. Yet, this population faces the long-term effects of occupational exposures and multiple difficulties related to living and aging in rural area (limited access to shops, services, and practitioners). However, these difficulties may be counter-balanced by advantages related to healthier lifestyle, richer social support and better living environment. The general aim of the AMI cohort was to study health and aging in elderly farmers living in rural area through a multidisciplinary approach, with a main focus on dementia. METHODS/DESIGN: The study initially included 1 002 participants, randomly selected from the Farmer Health Insurance rolls. Selection criteria were: being 65 years and older; living in rural area in Gironde (South-Western France); being retired from agriculture after at least 20 years of activity and being affiliated to the Health Insurance under own name. The study started in 2007, with two follow-up visits over 5 years. Baseline visits were conducted at home by a neuropsychologist then by a geriatrician for all cases suspected of dementia, Parkinson's disease and depression (to confirm the diagnosis), and by a nurse for others. A large panel of data were collected through standardised questionnaires: complete neuropsychological assessment, material and social living environment, psychological transition to retirement, lifestyle (smoking, alcohol and diet), medications, disability in daily living, sensory impairments and some clinical measures (blood pressure, depression symptomatology, anxiety, visual test, anthropometry...). A blood sampling was performed with biological measurements and constitution of a biological bank, including DNA. Brain MRI were also performed on 316 of the participants. Finally, the three-year data on health-related reimbursements were extracted from the Health System database (medications, medical and paramedical consultations, biological examinations and medical devices), and the registered Long-Term Diseases (30 chronic diseases 100% covered by the Insurance System). DISCUSSION: AMI is the first French longitudinal study on health and aging set up in a population of elderly farmers living in rural area through a multidisciplinary approach.

Factors influencing general practitioners in the referral of elderly cancer patients.

BACKGROUND: A number of studies have identified advanced age as a barrier to accessing specialised oncological care. Many factors can influence the care provided for elderly patients after a diagnosis of cancer has been established or is suspected. Only one European study has analysed the decision processes leading general practitioners (GPs) to refer elderly patients with cancer to oncologists. The objectives of the current study are to describe the factors that influence these decisions and to identify the particular factors and GP characteristics that are associated with systematic referral of these patients in South-West France. METHODS: This is a cross-sectional study on a representative sample of GPs in Aquitaine, South-West France. Questionnaire items were selected using a Delphi consensus approach and sent by post. Two logistic regression models were constructed to investigate GPs' decisions to refer these patients. RESULTS: The response rate obtained was 30%. Half of the general practitioners reported "always" referring their elderly cancer patients to oncologists. More than 75% reported being influenced by patient-related elements (patient and/or family wishes, comorbid factors, unsuitability of invasive investigations, physical and mental autonomy), by cancer-related elements (severity of symptoms, expected side-effects) and an organisational element (whether the general practitioner was used to collaborating with oncologists). Logistic regression analysis showed that cancer site and organisational difficulties in patient management were significantly associated with the decision to refer elderly patients with early-stage cancer. For advanced stages, oncology training, patient age, organisational difficulties in patient management and stage of cancer were significantly associated with the decision to refer elderly patients. CONCLUSIONS: Cancer-linked factors and organisational difficulties have been highlighted as influencing the decisions of GPs in the referral of elderly patients to a cancer team. These results highlight the need to implement continuous medical education specific for the management of elderly patients, to better apprehend the nature of these difficulties and to suggest solutions suited to local settings.

Epidemiology and prognostic significance of chronic kidney disease in the elderly--the Three-City prospective cohort study.

BACKGROUND: Little is known about normal kidney function level and the prognostic significance of low estimated glomerular filtration rate (eGFR) in the elderly. METHODS: We determined age and sex distribution of eGFR with both the Modification of Diet in Renal Disease (MDRD) study and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations in 8705 community-dwelling elderly aged ≥ 65 years and studied its relation to 6-year mortality. In a subsample of 1298 subjects examined at 4 years, we assessed annual eGFR decline and clinically relevant markers including microalbuminuria (3-30 mg/mmol creatinine) with diabetes, proteinuria ≥ 50 mg/mmol, haemoglobin <11 g/L or resistant hypertension despite three drugs. RESULTS: Median (interquartile range) MDRD eGFR was 78 (68-89) mL/min/1.73 m(2) in men and 74 (65-83) in women; there were 79 (68-87) and 77 (67-85) for CKD-EPI eGFR, respectively. Prevalence of MDRD eGFR <60 mL/min/1.73 m(2) was 13.7% and of CKD-EPI eGFR was 12.9%. After adjustment for several confounders, only those with an eGFR <45 mL/min/1.73 m(2) had significantly higher all-cause and cardiovascular mortality than those with an eGFR of 75-89 mL/min/1.73 m(2) whatever the equation. In the subsample men and women with an MDRD eGFR of 45-59 mL/min/1.73 m(2), 15 and 13% had at least one clinical marker and 15 and 3% had microalbuminuria without diabetes, respectively; these percentages were 41 and 21% and 23 and 10% in men and women with eGFR <45, respectively. Mean MDRD eGFR decline rate was steeper in men than in women, 1.75 versus 1.41 mL/min/1.73 m(2)/year. CONCLUSIONS: Moderately decreased eGFR is more often associated with clinical markers in men than in women. In both sexes, eGFR <45 mL/min/1.73 m(2) is related to poor outcomes. The CKD-EPI and the MDRD equations provide very similar prevalence and long-term risk estimates in this elderly population.

Prognostic Value of Routinely Measured Inflammatory Biomarkers in Older Cancer Patients: Pooled Analysis of Three Cohorts.

BACKGROUND: The prognostic assessment of older cancer patients is complicated by their heterogeneity. We aimed to assess the prognostic value of routine inflammatory biomarkers. METHODS: A pooled analysis of prospective multicenter cohorts of cancer patients aged ≥70 was performed. We measured CRP and albumin, and calculated Glasgow Prognostic Score (GPS) and CRP/albumin ratio. The GPS has three levels (0 = CRP ≤ 10 mg/L, albumin ≥ 35 g/L, i.e., normal values; 1 = one abnormal value; 2 = two abnormal values). One-year mortality was assessed using Cox models. Discriminative power was assessed using Harrell's C index (C) and net reclassification improvement (NRI). RESULTS: Overall, 1800 patients were analyzed (mean age: 79 ± 6; males: 62%; metastases: 38%). The GPS and CRP/albumin ratio were independently associated with mortality in patients not at risk of frailty (hazard ratio [95% confidence interval] = 4.48 [2.03-9.89] for GPS1, 11.64 [4.54-29.81] for GPS2, and 7.15 [3.22-15.90] for CRP/albumin ratio > 0.215) and in patients at risk of frailty (2.45 [1.79-3.34] for GPS1, 3.97 [2.93-5.37] for GPS2, and 2.81 [2.17-3.65] for CRP/albumin ratio > 0.215). The discriminative power of the baseline clinical model (C = 0.82 [0.80-0.83]) was increased by adding GPS (C = 0.84 [0.82-0.85]; NRI events (NRI+) = 10% [2-16]) and CRP/albumin ratio (C = 0.83 [0.82-0.85]; NRI+ = 14% [2-17]). CONCLUSIONS: Routine inflammatory biomarkers add prognostic value to clinical factors in older cancer patients.

[Contributions of a geriatric outpatient consultation in a dialysis facility]. / Apports d'une consultation gériatrique dans une association d'antennes d'auto-dialyse.

CONTEXT: The role of comprehensive geriatric assessment for older patients with advanced chronic kidney disease still needs to be defined. In this population, data is lacking on the care proposals made by geriatricians during comprehensive geriatric assessment and on the follow-up of these proposals. OBJECTIVES: To describe a population of older outpatients with advanced renal disease seen at a geriatric consultation, and geriatric syndromes identified. To study care suggestions made by the geriatrician, and the follow-up of these suggestions. METHODS: Retrospective monocentric study, including all outpatients treated with hemodialysis and seen at the geriatric consultation implemented in a dialysis facilities network in Aquitaine region, France, from 2014 to 2017. Six domains were analysed: functional independence, cognition, gait/balance, mood, nutrition and drug prescription. RESULTS: Among 49 patients, mean age 79 years, 50% had a loss of independence, 32% cognitive impairment, 24% mood disturbance, 55% gait or balance disturbance, and 65% potentially inappropriate medications. The most frequent care suggestions of the geriatrician were drugs optimisation, intervention of a psychologist, a dietetician or a speech and language therapist, home support service implementation, and the exploration of cognitive impairment. Suggestions of intervention of other healthcare professionals, drug optimisation and biological/imaging tests were followed in respectively 46, 33 and 18% of cases. CONCLUSION: A geriatric outpatient consultation in a nephrology facility allows identification of frequent and multiples geriatric syndromes, requiring coordinated interventions. Collaboration between healthcare professionals, including a geriatrician, should be reinforced to improve design and follow-up of the individualised care plan for older patients with advanced chronic kidney disease.

Discrepancy Between Equations Estimating Kidney Function in Geriatric Care: A Study of Implications for Drug Prescription.

BACKGROUND: In older patients, the agreement is low between creatinine clearance estimated with the Cockcroft-Gault equation (eCrCl) and glomerular filtration rate estimated with the Chronic Kidney Disease Epidemiology Collaboration equation (eGFRCKD-EPI). The implications of these discrepancies for drug prescription have so far been assessed only for a few selected molecules. OBJECTIVE: The aim of this study was to investigate the proportion of geriatric patients receiving drugs with a different recommended dose or indication (i.e. an adjustment discrepancy) depending on eCrCl versus eGFRCKD-EPI estimates of kidney function. METHODS: Patients admitted to acute geriatric care units in our university hospital were eligible for inclusion. All drug classes were studied. We retrospectively determined recommended prescriptions according to eCrCl and eGFRCKD-EPI. RESULTS: Sixty percent of patients received at least one drug requiring dose adjustment and/or received a drug with a relative contraindication based on their estimated kidney function. Thirty-one percent of patients received at least one drug with an adjustment discrepancy: 20% received at least one drug for which the recommended dose differed depending on eCrCl versus eGFRCKD-EPI estimates of kidney function, 4% received a drug with a relative contraindication according to eCrCl but not eGFRCKD-EPI, and 7% received both. Factors independently associated with an adjustment discrepancy were older age and lower weight. Main drug classes involved were benzodiazepines, anticoagulants, and anti-microbial drugs. CONCLUSION: In acute geriatric care units, recommended drug dose adjustments are frequently discordant according to the equations used to estimate kidney function, notably for benzodiazepines, anticoagulants, and anti-microbial drugs. The consequences for treatment efficacy and safety should be investigated.

The prognostic value of G8 for functional decline.

PURPOSE: Clinical experience suggests that functional decline (FD) during treatment may have a major adverse impact on outcome. Geriatric assessment of older patients before cancer treatment is usually based on use of a screening tool (such as G8) followed by comprehensive geriatric assessment (CGA). However, many oncology teams cannot implement geriatric oncology management due to non-availability of geriatricians. Consequently, we decided to evaluate whether a procedure using G8 and routinely available factors could help oncologists foresee the outcome in patients ≥70: we firstly evaluated whether functional decline is a determinant of early death, then searched for predictors of early functional decline (measured before initiation of the second cycle of chemotherapy), including G8 but voluntarilly excluding CGA. METHODS: We tested the value of clinical, biological factors and early FD to predict early death on a cohort of 292 patients (≥70 years) treated with first-line chemotherapy. We then used a logistic regression model to search for pretreatment predictors of FD, including the same factors and G8 but excluding CGA. RESULTS: FD occurred in 48 patients. In multivariate analyses, early FD (OR = 4.13, 95% CI [1.89; 9.04], p < .01), disease extension (OR = 4.55, 95% CI [1.96; 10.57]; p < .01), and being male (OR = 2.59, 95% CI [1.12; 5.97], p = .02) were significant prognostic factors for early death; G8 was the only significant factor associated with FD (OR = 4.38, 95% CI [1.28; 14.92], p = .018). CONCLUSIONS: FD has an important prognostic significance in patients ≥70 treated with chemotherapy, and G8 predicts for its occurrence. These data reinforce the routine use of G8 in the management of these patients.

Determinants of functional decline in older adults experiencing cancer (the INCAPAC study).

BACKGROUND: Previous studies have reported on the higher risk of functional decline among older patients with cancer. However, few have focused on factors of functional decline in older persons with cancer and are mainly hospital-based and focus on consequences of cancer treatment. The aim of the study was to identify determinants of functional decline in older subjects with cancer in a population-based study. METHODS: Using cancer registries, we identified older subjects (age ≥ 65 years) with cancer in three prospective cohort studies from Gironde, a French department. Functional status was measured using the Instrumental Activities of Daily Living (IADL) and the basic Activities of Daily Living (ADL) scales, and functional decline was measured between cancer pre- and post-diagnosis visits. Studied variables were demographic and socioeconomic (age at diagnosis, sex, living alone, education), cancer-related (stage at diagnosis, treatment received), smoking status, health-related (polypharmacy, depressive symptomatology), and geriatric-specific (cognitive impairment or dementia). Analyses were performed using logistic regression models. RESULTS: Age (≥85 years), cognitive impairment or dementia, and advanced stage at diagnosis were associated with a higher risk of ADL limitations, whether considering death or not. Age (≥85 years), education and polypharmacy were associated with a higher risk of ADL and/or IADL limitations. CONCLUSIONS: We identified factors that could impact on ADL and/or IADL limitations in older patients with cancer. The information on these determinants is useful in clinical settings to identify patients with cancer at high risk of functional decline.

Non-REM Sleep Characteristics Predict Early Cognitive Impairment in an Aging Population.

Objective: Recent research suggests that sleep disorders or changes in sleep stages or EEG waveform precede over time the onset of the clinical signs of pathological cognitive impairment (e.g., Alzheimer's disease). The aim of this study was to identify biomarkers based on EEG power values and spindle characteristics during sleep that occur in the early stages of mild cognitive impairment (MCI) in older adults. Methods: This study was a case-control cross-sectional study with 1-year follow-up of cases. Patients with isolated subjective cognitive complaints (SCC) or MCI were recruited in the Bordeaux Memory Clinic (MEMENTO cohort). Cognitively normal controls were recruited. All participants were recorded with two successive polysomnography 1 year apart. Delta, theta, and sigma absolute spectral power and spindle characteristics (frequency, density, and amplitude) were analyzed from purified EEG during NREM and REM sleep periods during the entire second night. Results: Twenty-nine patients (8 males, age = 71 ± 7 years) and 29 controls were recruited at T0. Logistic regression analyses demonstrated that age-related cognitive impairment were associated with a reduced delta power (odds ratio (OR) 0.072, P < 0.05), theta power (OR 0.018, P < 0.01), sigma power (OR 0.033, P < 0.05), and spindle maximal amplitude (OR 0.002, P < 0.05) during NREM sleep. Variables were adjusted on age, gender, body mass index, educational level, and medication use. Seventeen patients were evaluated at 1-year follow-up. Correlations showed that changes in self-reported sleep complaints, sleep consolidation, and spindle characteristics (spectral power, maximal amplitude, duration, and frequency) were associated with cognitive impairment (P < 0.05). Conclusion: A reduction in slow-wave, theta and sigma activities, and a modification in spindle characteristics during NREM sleep are associated very early with a greater risk of the occurrence of cognitive impairment. Poor sleep consolidation, lower amplitude, and faster frequency of spindles may be early sleep biomarkers of worsening cognitive decline in older adults.

Atypical Presentation of Bacteremia in Older Patients Is a Risk Factor for Death.

BACKGROUND: The absence of fever in bacteremia in patients who are older is known to delay diagnosis. Our objective was to determine whether atypical presentation was associated to mortality as a result of bacteremia in this patient cohort as well as possible factors associated with this atypical presentation. METHODS: We conducted an observational prospective study in 2 French university hospitals in 2016-2017 including patients ages ≥75 years with bacteremia. Atypical presentation was defined as the absence of a temperature ≥38.3°C or <36°C, chills, or hypotension. Mortality and dependence for activities of daily living (ADL) were recorded at 1 week (D7) and 3 months (D90). RESULTS: Among the 151 patients (mean age 85.4±5.8 years) enrolled, atypical presentation prevalence was 21.2%. D7 and D90 mortality rates were 7.9% and 40.0%, respectively. Atypical presentation was independently associated with D7 (odds ratio (OR) 4.46, 95% confidence interval (CI) 1.04-19.24) and D90 mortality (OR 3.76, 95% CI 1.30-10.92) after controlling for other prognostic factors. Patients with diabetes and those infected with Staphylococcus aureus were more likely to have atypical signs of infection. ADL score decreased from 3.6±2.0 before bacteremia to 2.8±2.1 at D90 (P <0.001). CONCLUSION: Patients who are older with bacteremia have poor vital and functional prognoses in the short and long terms. The absence of typical signs of infection is associated with mortality. Blood culture should be considered for patients who are older, especially with diabetes with acute unexplained clinical manifestations.

Undernutrition in elderly patients with cancer: target for diagnosis and intervention.

In recent years, geriatricians and oncologists have worked together to evaluate elderly patients with cancer before and during treatment, to estimate the balance between the efficacy and safety of chemotherapy and to upgrade treatment in this population according to their comorbidity and physiological status. The clinical and biological factors of this population need to be assessed in multidisciplinary comprehensive geriatric assessment (CGA) in order to optimize treatment without inducing major adverse effects. We reviewed the nutritional aspects of this evaluation that highlight the impact of undernutrition on poor survival. In this paper we briefly describe tumoral cachexia (molecular and physiological), the impact of undernutrition on cancer prognosis (predictive factors), therapeutic effects of cancer on nutritional status, nutritional indicators (biological, anthropometric) and undernutrition in the elderly (specific needs of this population). The potential for nutritional intervention in geriatric oncology with regard to CGA is explored.

Sociodemographic, socioeconomic, and clinical determinants of survival in patients with cancer: A systematic review of the literature focused on the elderly.

Studies on cancer survival have revealed disparities not only between the elderly and their younger counterparts, but also among the elderly themselves. The aim of this work was to identify sociodemographic, socioeconomic, clinical, and care-related determinants of survival or mortality in older patients with cancer by a systematic synthesis of the literature. Understanding these factors is of great value for guiding health policies and programs aimed at reducing cancer survival disparities. We conducted a search of MEDLINE and SCOPUS databases under PRISMA guidelines. Results were limited to articles published in English and French from 2005 to 2015, and focused on elderly patients with cancer. The article selection was performed in a stepwise fashion: title, abstract, and full-text selection. Studied determinants and results of each article were synthesized. Forty-five articles were eligible and included in the study. We observed different ways of measuring socioeconomic status, comorbidities, and treatment among studies. Cancer-specific and overall survival were the main studied outcomes. Advanced age, low income, low socioeconomic status, presence of comorbidities, advanced stage, and poor tumor grade were found to be associated with lower survival or higher mortality. On the other hand, female gender and being married were predictive of increased survival or lower mortality. The next logical step is to carry out studies on elderly patients from different countries and to incorporate pertinent factors in a unique model. Moreover, specific geriatric health impairments should be taken into account in further research because of their association with survival.

Determinants of cancer treatment and mortality in older cancer patients using a multi-state model: Results from a population-based study (the INCAPAC study).

INTRODUCTION: Several studies have reported disparities in the care management and survival of older cancer patients. The aim of our study was to identify determinants of treatment administration in this population of cancer patients aged over 65 years taking into account competing risks of death. METHODS: The INCAPAC study is a population-based study. Four cancer registries and three prospective cohort studies on older subjects (age ≥65 years) from Gironde, a French department, were merged to identify older cancer patients. We used a non-parametric multi-state model including three states (cancer, treatment and all-cause death). This model allowed studying determinants of treatment administration (all treatments including curative, symptomatic and palliative treatments) and mortality considering that patients can move from cancer state to death state, either directly or through the treatment phase. Studied variables were demographic and socioeconomic-, cancer-, health-, and geriatric-related. RESULTS: A total of 450 patients were included in the analyses. They were mainly aged 85 and over, men and educated. Among included patients, 372 (83%) received cancer treatment. In the final multivariate model, dementia was associated with a lower likelihood of receiving cancer treatment (HR = 0.68, 95% CI = 0.47-0.99). In treated patients, age, sex, comorbidities, dependency and stage at diagnosis were associated to all-cause mortality, and in untreated patients, diagnosis of dementia and stage at diagnosis were associated to mortality. CONCLUSION: Further studies are necessary to understand the impact of geriatric impairments on treatment administration and to develop clinical practice guidelines.

Relevance of G8 scale in referring elderly patients with aortic stenosis requiring a TAVI for a geriatric consultation.

Aortic stenosis (AS) may soon become a significant public health issue. Referring elderly suffering from aortic stenosis for a transcatheter aortic valve implantation (TAVI) versus surgical valve replacement might be difficult and requires a multidisciplinary staff. G8 is a geriatric screening scale for frailty, validated in oncogeriatry. We study sensibility and specificity of G8 used by cardiologists in comparison to a comprehensive geriatric assessment (CGA) performed by geriatrician. Prospective study, from February to July 2015, in Bordeaux university Hospital, France. Every elderly admitted for a TAVI had a G8 scale performed by cardiologist and CGA by a geriatrician in blind. Comorbidities were assessed using Cumulative Illness Rating Scale in his geriatric version (CIRS-G). CGA was abnormal if: MMSE <24/30 or GDS ≥7/15 or ADL ≤5/6 or IADL ≤7/8 or TUG ≥20 seconds or if malnutrition was noticed. G8 was abnormal if ≤14/17. We calculated sensibility, specificity, positive and negative predictive value in comparison to gold-standard CGA. 49 patients were included (55.1% women, mean age 84.8 years old). Nearly half of the patients (48.96%) had multiple comorbidities (CIRS G score >3 for at least three items excluding the cardiology item). 38 CGA were abnormal (77.55%) and 41 G8 (83.67%). G8 had a sensibility of 100% (IC 95% [0.9-1]), a specificity of 72.7% (IC 95% [0.43-0.9]), a positive predictive value of 92.6% and a negative prospective value of 100% (IC: 95%). G8 scale seems to be an efficient geriatric screening tool for frailty in elderly undergoing TAVI in comparison to CGA. Simple and useful, G8 scale could be performed by cardiologists in older patients with AS for identifying patients with a geriatric risk profile in consultation before surgery. Further studies with bigger samples are needed to confirm these results.

Prevalence and Co-Occurrence of Geriatric Syndromes in People Aged 75 Years and Older in France: Results From the Bordeaux Three-city Study.

BACKGROUND: Geriatric syndromes (GSs) are often the result of cumulative insults to multiple organ systems and are considered common in older adults. However, their frequency and co-occurrence are not well known in the elderly population. This study aimed to determine the prevalence of several GSs and to analyze the co-occurrence of these syndromes in a general population of elderly individuals. METHODS: A cross-sectional analysis of 630 adults aged 75 years or older participating in the 10-year follow-up of the Bordeaux sample of the French Three-City Study was conducted. The following 10 GSs were assessed: physical frailty, dementia and cognitive impairment, depressive symptoms, polymedication, social isolation, thinness, falls, dependence, sensory deficit, and incontinence. The prevalence of the 10 GSs was estimated, and multiple correspondence analysis (MCA) models were used to explore the mutual associations between these GSs. RESULTS: The mean age of the participants was 83.3 years; 69% were women, and 80.5% [95% confidence interval (CI) = 76.3-82.7] had at least one GS. The most frequent GSs were polymedication (50.6% 95%CI = 46.7-54.5) and falls (43.1% 95%CI = 38.4-46.1). The MCA models identified two major dimensions of the 10 GSs: "Dementia-Dependence-Incontinence" and "Frailty-Depression-Isolation." CONCLUSIONS: GSs were very common in this French elderly population and were grouped into two major dimensions: the "Dementia-Dependence-Incontinence" and "Frailty-Depression-Isolation."

Evolution of prevalence of depressive symptoms and antidepressant use between 1988 and 1999 in a large sample of older French people: Results from the personnes agées quid study.

OBJECTIVES: To describe the evolution of prevalence of depressive symptoms and antidepressant use between 1988 and 1999 in a large representative sample of older community-dwelling French people. DESIGN: Prospective cohort designed in 1988/89 to study cerebral and functional aging. SETTING: Urban and rural communities in southwestern France. PARTICIPANTS: Three thousand six hundred thirty-seven adults aged 65 and older living in noninstitutional settings at baseline. MEASUREMENTS: Participants were interviewed 3, 5, 8, and 10 years after the initial data collection. Depressive symptomatology was evaluated using a French version of the Center for Epidemiological Studies Depression Scale. Longitudinal analysis of the prevalence of depressive symptomatology was performed using a logistic mixed model adjusted for antidepressant use, sex, age, education level, living conditions, psychiatric antecedents, drug consumption, and diagnosis of dementia. RESULTS: Over the 10 years of follow-up, the prevalence of depressive symptomatology decreased from 13.8% to 8.3%. This decrease was statistically significant even after adjustment (odds ratio = 0.88 per increased year, 95% confidence interval = 0.85-0.90) and was more pronounced in subjects having reported previous depression at baseline. During the same period, antidepressant use rose from 5.2% to 11.9%, mainly due to increased use of selective serotonin reuptake inhibitors. Furthermore, the proportion of subjects who had depressive symptoms and did not use antidepressants decreased from 11.8% to 6.2%. CONCLUSION: This study suggests better management of late-life depression in the last decade and illustrates the heterogeneity of depression disorder in late life.

Detection of frailty in elderly cancer patients: Improvement of the G8 screening test.

OBJECTIVE: The G8 is a screening test to identify frail elderly patients with cancer. Objectives were to design and evaluate the performance of alternative tests taking into account other predictive domains for frailty. METHODS: We conducted a literature review to identify predictive factors of frailty. Using a Delphi consensus, we collected 24 European experts' opinions to validate the most relevant items to improve the G8. Alternative tests were created and performance assessed on a development population (ONCODAGE cohort). The highest performing test was compared to the G8, and validated through both an internal and an external population validation (Aquitaine Geriatric Oncology cohort). RESULTS: The study population consisted of 1435 patients (ONCODAGE cohort) and 364 patients (Aquitaine Geriatric Oncology cohort). Twenty-three experts validated two items with a strong consensus (>75%): modification of the threshold for the G8 polypharmacy item to six drugs per day and replacement of the G8 item on neuropsychological problems by four Instrumental Activities of Daily Living (IADL) items predictive of incident dementia, creating three modified G8 tests (addition of either item, or both). Only the G8 IADL-modified test had better performance than the G8 when tested on the ONCODAGE cohort: sensitivity=77%, specificity=67%. This test was validated on the internal (sensitivity=78%, specificity=71%) and external (sensitivity=88%, specificity=69%) validation populations. CONCLUSION: Adding the four IADL items improves the performance of the G8. We have developed and validated a G8-modified test that is more specific than the G8 to detect frail elderly, while still sensitive and feasible in less than 10 min.
