RESUMO

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.

RESUMO

BACKGROUND: Half of cancer cases occur in patients aged 70 and above. Majority of older patients are eligible for chemotherapy but evidence for treating this population is sparse and severe toxicities affect more than half of them. Determining prognostic biomarkers able to predict poor chemotherapy tolerance remains one of the major issues in geriatric oncology. Ageing is associated with body composition changes (increase of fat mass and loss of lean mass) independently of weight-loss. Previous studies suggest that body composition parameters (particularly muscle mass) may predict poor chemotherapy tolerance. However, studies specifically including older adults on this subject remain sparse and the majority of them study body composition based on computed tomography (CT) scanner (axial L3 section) muscle mass estimation. This method is to date not validated in elderly cancer patients. METHODS: This trial (Fraction) will evaluate the discriminative ability of appendicular lean mass measured by dual-energy X-ray absorptiometry (DXA) to predict severe toxicity incidence in older cancer-patients treated with first-line chemotherapy. DXA is considered the gold standard in body composition assessment in older adults. Patient's aged ≥70 diagnosed with solid neoplasms or lymphomas at a locally advanced or metastatic stage treated for first-line chemotherapy were recruited. Patients completed a pre-chemotherapy assessment that recorded socio-demographics, tumor/treatment variables, laboratory test results, geriatric assessment variables (function, comorbidity, cognition, social support and nutritional status), oncological risk scores and body composition with DXA. Appendicular lean mass was standardized using evidence based international criteria. Participants underwent short follow-up geriatric assessments within the first 3 months, 6 months and a year after inclusion. Grade 3 to 5 chemotherapy-related toxicities, as defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) were assessed at each chemotherapy cycle. DISCUSSION: The finding that body composition is associated with poor tolerance of chemotherapy could lead to consider these parameters as well as improve current decision-making algorithms when treating older adults. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02806154 registered on October 2016.

RESUMO

Aging is characterized by several major changes, including altered body composition, which is associated with numerous negative clinical consequences such as sarcopenia, osteoporosis, and frailty. The study is to evaluate body composition parameters depending on age and sex in a population ranging from the young adult to the very old, and to identify break points in the association between body composition and age. In this cross-sectional study, we included the enrolment population of the French INSPIRE-T prospective cohort, accounting for 915 subjects (62% female). Age ranged from 20 to 93 years, median age (years) was 63 (IQR 27). Body composition (lean mass, fat mass, and bone mineral content) was assessed with dual-X-ray absorptiometry (DXA). Different break points in the relationship between age and body composition variables in males and females were identified using a segmented regression analysis adjusted on physical activity, nutritional status, educational level, and comorbidities. Lean mass decreased from the age of 55 years for males (CI 95% 44-66) and 31 years for females (CI 95% 23-39). For fat mass, we observed a trend towards an increase with age for males. For females, we observed an increase with age up to age 75 (CI 95% 62-86), followed by a decreasing trend. In this study, we described the relationship between body composition and age as a function of sex, establishing a foundation for further studies on predictive biomarkers of age-related body composition alteration.

RESUMO

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.

RESUMO

PURPOSE OF REVIEW: The present review describes and discusses the currently available definitions for sarcopenia from consensus studies. RECENT FINDINGS: Different sarcopenia definitions have been proposed in these last years. Six main approaches to an operative definition of sarcopenia have been identified. Although the first definitions were solely based on the assessment of the amount of muscle mass, current definitions seem to consistently recognize a bi-dimensional nature of sarcopenia. So, these approaches imply the need of simultaneously assessing both age-related quantitative (i.e. amount of muscle mass) and qualitative (i.e. muscle strength and function) declines of skeletal muscle. SUMMARY: Although current consensus exists about a bi-dimensional nature, the proposed approaches to measure sarcopenia are characterized by methodological differences. The majority of the operative definitions proposes to assess muscle mass as an index of appendicular muscle mass divided by squared height (evaluated by dual energy X-ray absorptiometry), assess strength using hand-held dynamometers, and assess function by evaluating gait speed at habitual pace over a short distance. Nevertheless, the clinically relevant thresholds and how to combine the three aspects in an operative definition in order to identify sarcopenia are heterogeneous. A main drawback is that supportive empirical data are missing for these conceptual definitions regarding the risk-assessment of different clinically significant adverse outcomes.

RESUMO

PURPOSE OF REVIEW: The review summarizes and discusses the proposed new definitions for sarcopenia and cachexia. It also highlights the overlapping of both conditions and the fact that these conditions frequently occur in elderly patients. RECENT FINDINGS: Sarcopenia is now recognized as a multifactorial geriatric syndrome. Cachexia is defined as a metabolic syndrome in which inflammation is the key feature and so cachexia can be an underlying condition of sarcopenia. Recently, cachexia has been defined as 'a complex metabolic syndrome associated with underlying illness and characterized by loss of muscle mass with or without loss of fat mass. The prominent clinical feature of cachexia is weight loss in adults'. Different recommendations have been proposed for the diagnosis of sarcopenia. At present, all definitions combine an assessment of muscle mass and muscle function (strength or physical performances such as gait speed). However, the relevance and the validation of these evolving definitions need to be assessed in future studies. SUMMARY: Although the recent definitions of sarcopenia and cachexia boost research in the field and define distinct entities, the cause behind the loss of muscle mass (whether cachexia or sarcopenia) may, however, be indistinguishable in clinical practice. Therefore, new therapeutic approaches, alone or in combination, could be targeted on both conditions.

RESUMO

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.

RESUMO

OBJECTIVE: To describe the characteristics and associated factors of Alzheimer disease (AD) patients with balance and gait impairments. METHODS: Balance and gait impairments were assessed in 380 AD patients using the Tinetti test. RESULTS: A total of 120 (31.5%) patients had an abnormal Tinetti test, 96 (25.2%) had balance impairments, and 72 (18.9%) patients presented gait impairments. Global Tinetti score was associated with age [odds ratio (OR), 1.09; 95% confidence interval (CI), 1.05-1.14], Mini-Mental State Examination (MMSE) score (OR, 0.94; 95% CI, 0.90-0.99), activities of daily living (ADL) score (OR, 0.62; 95% CI, 0.47-0.83), and being man (OR, 0.44; 95% CI, 0.25-0.78). Balance impairment was associated with age (OR, 1.11; 95% CI, 1.05-1.17), ADL score (OR, 0.60; 95% CI, 0.43-0.84), and being female (OR, 0.19; 95% CI, 0.08-0.49). Gait impairment was associated with age (OR, 1.09; 95% CI, 1.03-1.15), MMSE score (OR, 0.92; 95% CI, 0.87-0.98), ADL score (OR, 0.63; 95% CI, 0.46-0.87), body mass index (OR, 1.10; 95% CI, 1.01-1.18), presence of comorbidities (OR, 2.13; 95% CI, 1.14-3.96), and the Cornell score (OR, 2.97; 95% CI, 1.12-7.89). CONCLUSIONS: AD patients are frequently concerned with balance and gait impairments. These impairments were associated to factors related to the severity of the disease (low MMSE and low ADL); nonmodifiable factors such as age or sex; and modifiable factors such as depression, obesity, and presence of comorbidities.

RESUMO

BACKGROUND: Basal cell carcinoma (BCC), the most prevalent form of cancer worldwide, is a malignant skin neoplasm. It is locally invasive, with an exceptional incidence of reported metastasis. It can also be part of the Gorlin-Goltz syndrome, an autosomal dominant genetic disorder with high penetrance and variable expressivity, which is principally characterized by cutaneous BCC, odontogenic keratocysts, palmar and/or plantar pits, and falx cerebri calcification. OBSERVATION: We report the exceptional clinical observation of a 54-year-old man presenting bone metastasis from BCC in Gorlin-Goltz syndrome. CONCLUSION: Less than 300 cases of metastatic BCC have been reported in the literature. The present case is the second associated with Gorlin-Goltz syndrome.

RESUMO

Among elderly without cognitive impairment, poor physical performances have been reported to predict cognitive decline and dementia. Our aim was to explore the predictive value of balance impairment for cognitive decline in 686 community-dwelling Alzheimer's disease (AD) patients (REAL.FR study). Being unable to stand on one leg for five seconds or more defined balance impairment. Cognitive decline was assessed using the Mini-Mental Status Examination (MMSE) score. Co-morbidities, behavioral and psychological symptoms of dementia (BPSD) using the Neuropsychiatric Inventory score, medication, and level of education were assessed at the hospital. MMSE and balance were reported every six months during two years. Linear mixed model analyses were performed. At baseline, participants with balance impairment (15.2% of the sample) were significantly older, had a lower MMSE score and more BPSD, co-morbidities, and medication. After adjustment for the potential covariates, the presence of balance impairment at each assessment was associated with a mean MMSE decline of 9.2 (1.4) points at two years; having no balance impairment at each assessment was associated with a mean MMSE decline of 3.8 (0.3) points at two years (p < 0.001). An abnormal one-leg balance test is a marker of more advanced dementia and predicts a higher rate of cognitive decline.

RESUMO

BACKGROUND/AIMS: To assess if cardiovascular disease risk factors (CVDRF) are predictive factors for poorer evolution of Alzheimer's disease (AD) patients in terms of cognitive decline. METHODS: The Réseau de la maladie d'Alzheimer - France (REAL.FR) study is a prospective multicentre cohort which has recruited 686 community-dwelling patients presenting mild to moderate AD. The presence of CVDRF and associated treatments was recorded at baseline. The rate of cognitive decline of AD patients was assessed using the Mini Mental State Examination (MMSE) and the Alzheimer Disease Assessment Scale cognitive subscale (ADAS-Cog), after 2 years of follow-up. RESULTS: Of the 629 patients at baseline, 268 (42.6%) had no CVDRF, 256 (40.7%) reported 1 CVDRF and 105 (16.7%) reported 2-3. At inclusion, hypertension was present in 44.1% of patients, hypercholesterolaemia in 22.6% and diabetes in 9.4%. No statistically significant differences (p values of 0.9 for MMSE and 0.8 for ADAS-Cog) in mean cognitive decline after 2 years of follow-up were found comparing different subgroups of patients with CVDRF to the non-CVDRF group. CONCLUSIONS: Although there is evidence that CVDRF contribute to the onset of AD, these results suggest that CVDRF may not be part of the underlying processes that affect progression of AD.

RESUMO

OBJECTIVES: Screening for sarcopenia in daily practice can be challenging. Our objective was to explore whether the SARC-F questionnaire is a valid screening tool for sarcopenia (defined by the Foundation for the National Institutes of Health [FNIH] criteria). Moreover, we evaluated the physical performance of older women according to the SARC-F questionnaire. DESIGN: Cross-sectional study. PARTICIPANTS: Data from the Toulouse and Lyon EPIDémiologie de l'OStéoporose study (EPIDOS) on 3025 women living in the community (mean age: 80.5 ± 3.9 years), without a previous history of hip fracture, were assessed. MEASUREMENTS: The SARC-F self-report questionnaire score ranges from 0 to 10: a score ≥4 defines sarcopenia. The FNIH criteria uses handgrip strength (GS) and appendicular lean mass (ALM; assessed by DXA) divided by body mass index (BMI) to define sarcopenia. Outcome measures were the following performance-based tests: knee-extension strength, 6-m gait speed, and a repeated chair-stand test. The associations of sarcopenia with performance-based tests was examined using bootstrap multiple linear-regression models; adjusted R2 determined the percentage variation for each outcome explained by the model. RESULTS: Prevalence of sarcopenia was 16.7% (n = 504) according to the SARC-F questionnaire and 1.8% (n = 49) using the FNIH criteria. Sensibility and specificity of the SARC-F to diagnose sarcopenia (defined by FNIH criteria) were 34% and 85%, respectively. Sarcopenic women defined by SARC-F had significantly lower physical performance than nonsarcopenic women. The SARC-F improved the ability to predict poor physical performance. CONCLUSION: The validity of the SARC-F questionnaire to screen for sarcopenia, when compared with the FNIH criteria, was limited. However, sarcopenia defined by the SARC-F questionnaire substantially improved the predictive value of clinical characteristics of patients to predict poor physical performance.

RESUMO

The sustainability of healthcare systems worldwide is threatened by the absolute and relative increase in the number of older persons. The traditional models of care (largely based on a disease-centered approach) are inadequate for a clinical world dominated by older individuals with multiple (chronic) comorbidities and mutually interacting syndromes. There is the need to shift the center of the medical intervention from the disease to the biological age of the individual. Thus, multiple medical specialties have started looking with some interest at concepts of geriatric medicine in order to better face the increased complexity (due to age-related conditions) of their average patient. In this scenario, special interest has been given to frailty, a condition characterized by the reduction of the individual's homeostatic reserves and increased vulnerability to stressors. Frailty may indeed represent the fulcrum to lever for reshaping the healthcare systems in order to make them more responsive to new clinical needs. However, the dissemination of the frailty concept across medical specialties requires a parallel and careful consideration around the currently undervalued role of geriatricians in our daily practice.

RESUMO

OBJECTIVES: The main objective of the present work is to evaluate the feasibility of harmonising the available information from different independent databases, in order to build an integrated database to study frailty. MATERIAL AND METHODS: This work is based on the European project, Integral Approach to the Transition between Frailty and Dependence on older adults: Patterns of occurrence, identification tools and model of care (INTAFRADE), developed by 4 groups, 3 in Spain and one in France. Each partner provided their databases related to the study of frailty. As a previous step to the creation of an integrated database the characteristics and variables included in each study were mapped, specifying whether their harmonisation was possible or not. RESULTS: A total of 30 different variables that corresponded to 8 dimensions were identified: Sociodemographic and social characteristics, health status, lifestyle habits, anthropometric measures, other physical measurements, use of health services, and adverse health results. Of them all, 28 (93%) variables were harmonisable, although only 20% were present in all databases, with 47% in 3 of them. In relation to the frailty instruments, all of them were lacking at least 50% of the items. The harmonisation process will allow us to jointly analyse information available on 2,361 people. CONCLUSIONS: The European INTAFRADE study will allow a deeper understanding of the frailty process in older people by harmonising information from heterogeneous databases.

RESUMO

BACKGROUND: Current operational definitions of sarcopenia are based on algorithms' simultaneous considering measures of skeletal muscle mass and muscle-specific as well as global function. We hypothesize that quantitative and qualitative sarcopenia-related parameters may not be equally predictive of incident disability, thus presenting different clinical relevance. METHODS: Data are from 922 elder adults (mean age = 73.9 years) with no activities of daily living (ADL) impairment recruited in the "Invecchiare in Chianti" study. Incident disability in ≥1 ADL defined the outcome of interest. The specific capacities of following sarcopenia-related parameters at predicting incident ADL disability were compared: residuals of skeletal muscle mass, fat-adjusted residuals of skeletal muscle mass, muscle density, ankle extension strength, ratio ankle extension strength/muscle mass, gait speed, and handgrip strength. RESULTS: During the follow-up (median = 9.1 years), 188 (20.4%) incident ADL disability events were reported. Adjusted models showed that only gait speed was significantly associated with the outcome in both men (per standard deviation [SD] = 0.23 m/s increase, hazard ratio [HR] = 0.46, 95% confidence interval [CI] = 0.33-0.63; p < .001) and women (per SD = 0.24 m/s increase, HR = 0.64, 95% CI = 0.50-0.82; p < .001). In women, the fat-adjusted lean mass residual (per SD = 4.41 increase, HR = 0.79, 95% CI = 0.65-0.96; p = .02) and muscle density (per SD = 3.60 increase, HR = 0.76, 95% CI = 0.61-0.93; p = .01) were the only other parameters that predicted disability. In men, several of the tested variables (except muscle mass measures) reported significant results. CONCLUSIONS: Gender strongly influences which sarcopenia-related parameters predict disability. Gait speed was a powerful predictor of disability in both men and women, but its nonmuscle-specific nature should impose caution about its inclusion in definitions of sarcopenia.

BACKGROUND: The diversity of definitions proposed for sarcopenia has been rarely tested in the same population, and so far, their clinical utilities for predicting physical difficulties could not be clearly understood. Our objective is to report the prevalence of sarcopenia and the characteristics of sarcopenic community-dwelling older women according to the different definitions of sarcopenia currently proposed. We also assessed these definitions for their incremental predictive value over currently standard predictors for some self-reported difficulties in physical function and knee extension strength. METHODS: Cross-sectional analysis included data from 3025 non-disabled women aged 75 years or older without previous history of hip fracture from the inclusion visit of the EPIDémiologie de l'OStéoporose study. A total body composition evaluation was available for 2725 women. Sarcopenia was defined using six different definitions of sarcopenia based on different muscle mass, gait speed, and grip strength cut-offs. Self-reported difficulties in physical function and knee extension strength were collected. Logistic regression and multiple linear regression models were built for each physical dysfunction, and the predictive capacity of sarcopenia (one model for each definition) was studied using the C-statistic, the net reclassification index, or adjusted R(2). RESULTS: The estimated prevalence of sarcopenia ranged from 3.3-20.0%. Only 85 participants (3.1%) were identified having sarcopenia according to all definitions. All definitions were, to some degree, associated with self-reported difficulties in physical function and knee extension strength, but none improved the predictive ability of the self-reported difficulties in physical function. Conversely, all definitions accounted for a small but significant amount of explained variation for predicting knee extension strength. CONCLUSIONS: Prevalence of sarcopenia varies widely depending on the definition adopted. Based on this research, the current definitions for sarcopenia does not substantially increment the predictive value of clinical characteristics of patients to predict self-reported physical difficulties and knee extension strength.

RESUMO

BACKGROUND/OBJECTIVES: The clinical status of older individuals with multimorbidity can be further complicated by concomitant geriatric syndromes. This study explores multimorbidity patterns, encompassing both chronic diseases and geriatric syndromes, in geriatric patients attended in an acute hospital setting. DESIGN: Retrospective observational study. SETTING: Unit of Social and Clinical Assessment (UVSS), Miguel Servet University Hospital (HUMS), Zaragoza (Spain). Year, 2011. PARTICIPANTS: A total of 924 hospitalized patients aged 65 years or older. MEASUREMENTS: Data on patients' clinical, functional, cognitive and social statuses were gathered through comprehensive geriatric assessments. To identify diseases and/or geriatric syndromes that cluster into patterns, an exploratory factor analysis was applied, stratifying by sex. The factors can be interpreted as multimorbidity patterns, i.e., diseases non-randomly associated with each other within the study population. The resulting patterns were clinically assessed by several physicians. RESULTS: The mean age of the study population was 82.1 years (SD 7.2). Multimorbidity burden was lower in men under 80 years, but increased in those over 80. Immobility, urinary incontinence, hypertension, falls, dementia, cognitive decline, diabetes and arrhythmia were among the 10 most frequent health problems in both sexes, with prevalence rates above 20%. Four multimorbidity patterns were identified that were present in both sexes: Cardiovascular, Induced Dependency, Falls and Osteoarticular. The number of conditions comprising these patterns was similar in men and women. CONCLUSION: The existence of specific multimorbidity patterns in geriatric patients, such as the Induced Dependency and Falls patterns, may facilitate the early detection of vulnerability to stressors, thus helping to avoid negative health outcomes such as functional disability.
