Rendimiento de tres escalas de fragilidad para predecir resultados adversos a 30 días en los pacientes mayores dados de alta en los servicios de urgencias / Performance of 3 frailty scales for predicting adverse outcomes at 30 days in older patients discharged from emergency departments

Objetivo: Comparar la capacidad de tres escalas de fragilidad, Clinical Frailty Scale (CFS), Functional Index eMergency (FIM) e Identification Senior at Risk (ISAR), para predecir resultados adversos (RA) a 30 días en los pacientes mayores dados de alta desde el servicio de urgencias hospitalario (SUH). Método: Análisis secundario del registro FRAIL-Madrid que incluyó pacientes $ 75 años dados de alta de 10 SUH de Madrid durante un periodo de 3 meses entre 2018 y 2019. Se definió fragilidad como CFS $ 4, FIM $ 2 e ISAR $ 3. Las variables de resultado fueron revisita en urgencias, hospitalización, deterioro funcional, muerte y la variable compuesta por algún RA de los anteriores en los 30 días posteriores al alta del SUH. Resultados: Se incluyeron 619 pacientes, la edad media fue de 84 años (DE 7), 59,1% eran mujeres. Hubo 339 pacientes (54,8%) identificados como frágiles en el SUH según CFS $ 4, 386 (62,4%) según FIM $ 2 y 301 (48,6%) según ISAR $ 3. Hubo 226 pacientes (36,5%) que presentaron algún RA a los 30 días tras el alta (21,5% revisita, 12,6% hospitalización, 18,4% deterioro funcional y 3,6% muerte). El área bajo la curva (ABC) de la escala CFS fue de 0,66 (0,62-0,70; p = 0,022), de FIM 0,67 (0,62-0,71; p = 0,021) y de ISAR 0,64 (0,60-0,69; p = 0,023). La presencia de fragilidad fue un factor independiente de presentar algún RA a los 30 días tras el alta (CFS $ 4 ORa 3,18 [IC 95% 2,02-5,01, p < 0,001], FIM $ 2 ORa 3,49 [IC 95% 2,15-5,66, p < 0,001] e ISAR $ 3 ORa 2,46 [IC 95% 1,60-3,79, p < 0,001]). Conclusiones: Las tres escalas estudiadas –CFS, FIM, ISAR– son útiles y tienen una capacidad similar para identificar al paciente mayor frágil dado de alta del SUH con alto riesgo de presentar RA (muerte, deterioro funcional, hospitalización o revisita al SUH) a los 30 días.

Objective: To compare the ability of 3 frailty scales (the Clinical Frailty Scale [CFS], the Functional Index – eMergency [FIM], and the Identification of Seniors at Risk [ISAR] scale) to predict adverse outcomes at 30 days in older patients discharged from hospital emergency departments (EDs). Methods: Secondary analysis of data from the FRAIL-Madrid registry of patients aged 75 years or older who were discharged from Madrid EDs over a period of 3 months in 2018 and 2019. Frailty was defined by a CFS score over 4, a FIM score over 2, or an ISAR score over 3. The outcome variables were revisits to an ED, hospitalization, functionaldecline, death, and a composite variable of finding any of the previously named variables within 30 days of discharge. Results: A total of 619 patients were studied. The mean (SD) age was 84 (7) years, and 59.1% were women. The CFS identified as frail a total of 339 patients (54.8%), the FIM 386 (62.4%), and the ISAR 301 (48.6%). An adverse outcome occurred within 30 days in 226 patients (36.5%): 21.5% revisited, 12.6% were hospitalized, 18.4% experienced functional decline, and 3.6% died. The areas under the receiver operating characteristic curves were as follows: CFS, 0.66 (95% CI, 0.62-0.70; P = .022); FIM, 0.67 (95% CI, 0.62-0.71; P = .021), and ISAR, 0.64 (95% CI, 0.60-0.69; P = .023). Adjusted odds ratios (aOR) showed that frailty was an independent risk factor for presenting anyof the named adverse outcomes: aOR for CFS >4, 3.18 (95% CI, 2.02-5.01), P < .001; aOR for FIM > 2, 3.49 (95% CI, 2.15-5.66), P < .001; and aOR for ISAR >3, 2.46 (95% CI, 1.60-3.79), P < .001. Conclusions: All 3 scales studied — the CFS, the FIM and the ISAR — are useful for identifying frail older patients at high risk of developing an adverse outcome (death, functional decline, hospitalization, or revisiting the ED) within 30 days after discharge.

Malnutrition, Frailty, and Health-Related Quality of Life Among Rural Older Adults in Vietnam: A Cross-Sectional Study.

Purpose: Rural older adults are more likely to be malnourished than urban older adults, particularly those living in lower-middle-income countries like Vietnam. Therefore, this study aimed to address the prevalence of malnutrition and its association with frailty and health-related quality of life in older rural Vietnamese adults. Participants and Methods: This cross-sectional study was conducted on community-dwelling older adults (aged ≥ 60 years) living in a rural province in Vietnam. Nutritional status was determined using the Mini Nutritional Assessment Short Form (MNA-SF), and frailty was evaluated using the FRAIL scale. The 36-Item Short Form Survey (SF-36) was used to evaluate health-related quality of life. Results: Among the 627 participants, 46 (7.3%) were malnourished (MNA-SF score <8), and 315 (50.2%) were at risk of malnutrition (MNA-SF score: 8-11). Individuals with malnutrition had significantly higher rates of impairments in instrumental activities of daily living and activities of daily living than those without malnutrition (47.8% vs 27.4% and 26.1% vs 8.7%, respectively). The prevalence of frailty was 13.5%. Risk of malnutrition and malnutrition were associated with high risks of frailty, with odds ratios of 2.14 (95% confidence interval [CI]: 1.16-3.93) and 4.78 (1.86-12.32), respectively. Furthermore, the MNA-SF score was positively correlated with eight domains of the health-related quality of life among rural older adults. Conclusion: The prevalence rates of malnutrition, risk of malnutrition, and frailty were high among older adults in Vietnam. A strong association was observed between nutritional status and frailty. Therefore, this study reinforces the importance of screening for malnutrition and risk of malnutrition among older rural individuals. Further studies should explore whether early nutritional intervention reduces the risk of frailty among older adults and increase their health-related quality of life in the Vietnamese population.

Liver transplantation in the patient with physical frailty.

Frailty is a decline in functional reserve across multiple physiological systems. A key component of frailty is sarcopenia, which denotes a loss of skeletal muscle mass and impaired contractile function that ultimately result in physical frailty. Physical frailty/sarcopenia are frequent and contribute to adverse clinical outcomes before and after liver transplantation. Frailty indices, including the liver frailty index, focus on contractile dysfunction (physical frailty), while cross-sectional image analysis of muscle area is the most accepted and reproducible measure to define sarcopenia. Thus, physical frailty and sarcopenia are interrelated. The prevalence of physical frailty/sarcopenia is high in liver transplant candidates and these conditions have been shown to adversely impact clinical outcomes including mortality, hospitalisations, infections, and cost of care both before and after transplantation. Data on the prevalence of frailty/sarcopenia and their sex- and age-dependent impact on outcomes are not consistent in patients on the liver transplant waitlist. Physical frailty and sarcopenic obesity are frequent in the obese patient with cirrhosis, and adversely affect outcomes after liver transplantation. Nutritional interventions and physical activity remain the mainstay of management before and after transplantation, despite limited data from large scale trials. In addition to physical frailty, there is recognition that a global evaluation including a multidisciplinary approach to other components of frailty (e.g., cognition, emotional, psychosocial) also need to be addressed in patients on the transplant waitlist. Recent advances in our understanding of the underlying mechanisms of sarcopenia and contractile dysfunction have helped identify novel therapeutic targets.

Dynamic frailty risk assessment among older adults with multiple myeloma: A population-based cohort study.

Multiple myeloma (MM) is a cancer of older adults and those who are more frail are at high risk of poor outcomes. Current tools for identifying and categorizing frail patients are often static and measured only at the time of diagnosis. The concept of dynamic frailty (i.e. frailty changing over time) is largely unexplored in MM. In our study, adults with newly-diagnosed MM who received novel drugs between the years 2007-2014 were identified in the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked databases. Using a previously published cumulative deficit approach, a frailty index score was calculated at diagnosis and each landmark interval (1-yr, 2-yr, 3-yr post diagnosis). The association of frailty with overall survival (OS) both at baseline and at each landmark interval as well as factors associated with worsening frailty status over time were evaluated. Overall, 4617 patients were included. At baseline, 39% of the patients were categorized as moderately frail or severely frail. Among those who had 3 years of follow-up, frailty categorization changed post diagnosis in 93% of the cohort (78% improved and 72% deteriorated at least at one time point during the follow up period). In a landmark analysis, the predictive ability of frailty at the time of diagnosis decreased over time for OS (Harrell's C Statistic 0.65 at diagnosis, 0.63 at 1-yr, 0.62 at 2-yr, and 0.60 at 3-yr) and was inferior compared to current frailty status at each landmark interval. Our study is one of the first to demonstrate the dynamic nature of frailty among older adults with MM. Frailty may improve or deteriorate over time. Current frailty status is a better predictor of outcomes than frailty status at time of diagnosis, indicating the need for re-measurement in this high-risk patient population.

Importance analysis of psychosociological variables in frailty syndrome in heart failure patients using machine learning approach.

The prevention and diagnosis of frailty syndrome (FS) in cardiac patients requires innovative systems to support medical personnel, patient adherence, and self-care behavior. To do so, modern medicine uses a supervised machine learning approach (ML) to study the psychosocial domains of frailty in cardiac patients with heart failure (HF). This study aimed to determine the absolute and relative diagnostic importance of the individual components of the Tilburg Frailty Indicator (TFI) questionnaire in patients with HF. An exploratory analysis was performed using machine learning algorithms and the permutation method to determine the absolute importance of frailty components in HF. Based on the TFI data, which contain physical and psychosocial components, machine learning models were built based on three algorithms: a decision tree, a random decision forest, and the AdaBoost Models classifier. The absolute weights were used to make pairwise comparisons between the variables and obtain relative diagnostic importance. The analysis of HF patients' responses showed that the psychological variable TFI20 diagnosing low mood was more diagnostically important than the variables from the physical domain: lack of strength in the hands and physical fatigue. The psychological variable TFI21 linked with agitation and irritability was diagnostically more important than all three physical variables considered: walking difficulties, lack of hand strength, and physical fatigue. In the case of the two remaining variables from the psychological domain (TFI19, TFI22), and for all variables from the social domain, the results do not allow for the rejection of the null hypothesis. From a long-term perspective, the ML based frailty approach can support healthcare professionals, including psychologists and social workers, in drawing their attention to the non-physical origins of HF.

Peripheral modulation of antidepressant targets MAO-B and GABAAR by harmol induces mitohormesis and delays aging in preclinical models.

Reversible and sub-lethal stresses to the mitochondria elicit a program of compensatory responses that ultimately improve mitochondrial function, a conserved anti-aging mechanism termed mitohormesis. Here, we show that harmol, a member of the beta-carbolines family with anti-depressant properties, improves mitochondrial function and metabolic parameters, and extends healthspan. Treatment with harmol induces a transient mitochondrial depolarization, a strong mitophagy response, and the AMPK compensatory pathway both in cultured C2C12 myotubes and in male mouse liver, brown adipose tissue and muscle, even though harmol crosses poorly the blood-brain barrier. Mechanistically, simultaneous modulation of the targets of harmol monoamine-oxidase B and GABA-A receptor reproduces harmol-induced mitochondrial improvements. Diet-induced pre-diabetic male mice improve their glucose tolerance, liver steatosis and insulin sensitivity after treatment with harmol. Harmol or a combination of monoamine oxidase B and GABA-A receptor modulators extend the lifespan of hermaphrodite Caenorhabditis elegans or female Drosophila melanogaster. Finally, two-year-old male and female mice treated with harmol exhibit delayed frailty onset with improved glycemia, exercise performance and strength. Our results reveal that peripheral targeting of monoamine oxidase B and GABA-A receptor, common antidepressant targets, extends healthspan through mitohormesis.

Branched-chain amino acids supplementation improves liver frailty index in frail compensated cirrhotic patients: a randomized controlled trial.

BACKGROUND: Physical frailty is related with morbidity and mortality in patients with cirrhosis. Currently, there is no approved treatment of frailty in these patients. Here, we evaluated the efficacy of 16 weeks branched-chain amino acids (BCAA) supplementation on frailty in frail compensated cirrhotic patients. METHODS: After a 4-week run-in period consisted of dietary and exercise counseling, compensated cirrhotic patients with frailty, defined by liver frailty index (LFI)≥4.5, were randomly assigned (1:1) to BCAA or control group. The BCAA group received twice daily BCAAs supplementation (210 kcal, protein 13.5 g, BCAA 2.03 g) for 16 weeks. The primary outcome was frailty reversion. The secondary outcomes were changes in biochemistries, body composition evaluated by bioelectrical impedance analysis, and quality of life (QoL). RESULTS: 54 patients were prospectively enrolled (age 65.5 ± 9.9 years, 51.9% female, Child-Pugh A/B 68.5%/31.5%, MELD 10.3 ± 3.1). Baseline characteristics were similar between both groups. At week 16, BCAA group had a significant improvement in LFI (-0.36 ± 0.3 vs. -0.15 ± 0.28, P = 0.01), BMI (+ 0.51 ± 1.19 vs. -0.49 ± 1.89 kg/m2, P = 0.03), and serum albumin (+ 0.26 ± 0.27 vs. +0.06 ± 0.3 g/dl, P = 0.01). The proportion of frailty reversion at week 16 was significantly higher in BCAA group (36% vs. 0%, P < 0.001). Compared with baseline, BCAA group had a significant increase in skeletal muscle index (7.5 ± 1.6 to 7.8 ± 1.5 kg/m2, P = 0.03). Regarding the QoL, only the BCAA group had a significant improvement in all 4 domains of physical component score of the SF-36 questionnaire. CONCLUSIONS: A 16-week BCAA supplementation improved frailty in frail compensated cirrhotic patients. In addition, this intervention resulted in an improvement of muscle mass and physical domain of QoL in these patients. TRIAL REGISTRATION: This study was registered with Thai Clinical Trial Registry (TCTR20210928001; https://www.thaiclinicaltrials.org/# ).

Characterizing amblyopic perception under non-rivalrous viewing conditions.

Current assessments of interocular interactions in amblyopia often use rivalrous stimuli, with conflicting stimuli in each eye, which does not reflect vision under typical circumstances. Here we measure interocular interactions in observers with amblyopia, strabismus with equal vision, and controls using a non-rivalrous stimulus. Observers used a joystick to continuously report the perceived binocular contrast of dichoptic grating stimuli, identical except that the stimulus was contrast-modulated independently in each eye over time. Consistent with previous studies, a model predicting the time-course of perceived contrast found increased amblyopic eye attenuation, and reduced contrast normalization of the fellow eye by the amblyopic eye, in amblyopic participants compared to controls. However, these suppressive interocular effects were weaker than those found in previous studies, suggesting that rivalrous stimuli may overestimate the effects of amblyopia on interocular interactions during naturalistic viewing conditions.

A qualitative study exploring the lived experiences of patients living with mild, moderate and severe frailty, following hip fracture surgery and hospitalisation.

It is well recognised that hip fracture surgery is associated with a negative impact on short and long-term post-operative physical health and emotional well-being for patients. Furthermore, these patients are known to be frail with multiple co-morbidities. This study explores how frailty shapes the lived experiences of rehabilitation and recovery for patients who have undergone hip fracture surgery. Semi-structured interviews were conducted with sixteen participants, recently discharged from hospital following hip fracture surgery. Interpretative phenomenological analysis was applied to explore the lived experiences of frail patients and ascertain important themes. Patient experiences were captured in seven overarching themes: 1) the hospital as a place of "safety", 2) placing trust in others, 3) the slow recovery journey impeded by attitude and support, 4) maintaining autonomy and dignity whilst feeling vulnerable, 5) seeking a new normal, 6) loneliness and social isolation and 7) the ageing body. Based on our study findings, we have been able to suggest a number of opportunities to improve support for frailer patients in finding a new routine to their everyday lives, these include on-going physical and psychological support, information and education and a robust pathway for transition of care into the community. A conceptual thematic diagram is presented which helps to understand the experience and the complex needs of frail older people undergoing hip fracture surgery.

Assessment of the incremental prognostic value from the modified frailty index-5 in complete traumatic cervical spinal cord injury.

Frailty, as measured by the modified frailty index-5 (mFI-5), and older age are associated with increased mortality in the setting of spinal cord injury (SCI). However, there is limited evidence demonstrating an incremental prognostic value derived from patient mFI-5. We conducted a retrospective cohort study to evaluate in-hospital mortality among adult complete cervical SCI patients at participating centers of the Trauma Quality Improvement Program from 2010 to 2018. Logistic regression was used to model in-hospital mortality, and the area under the receiver operating characteristic curve (AUROC) of regression models with age, mFI-5, or age with mFI-5 was used to compare the prognostic value of each model. 4733 patients were eligible. We found that both age (80 y versus 60 y: OR 3.59 95% CI [2.82 4.56], P < 0.001) and mFI-5 (score ≥ 2 versus < 2: OR 1.53 95% CI [1.19 1.97], P < 0.001) had statistically significant associations with in-hospital mortality. There was no significant difference in the AUROC of a model including age and mFI-5 when compared to a model including age without mFI-5 (95% CI Δ AUROC [- 8.72 × 10-4 0.82], P = 0.199). Both models were superior to a model including mFI-5 without age (95% CI Δ AUROC [0.06 0.09], P < 0.001). Our findings suggest that mFI-5 provides minimal incremental prognostic value over age with respect to in-hospital mortality for patients complete cervical SCI.

The association between frailty and anxiety: A systematic review.

OBJECTIVES: Previous systematic reviews show a clear relationship between frailty and depression, however the association with anxiety is much less frequently explored. Previous single studies indicate evidence is mixed. We completed a systematic review and meta-analysis to identify the relationship between frailty and anxiety. METHODS: We searched five electronic databases for observational studies in older people in community, care home and outpatient settings with any/no health conditions that measured the association between anxiety and frailty using validated measures. Studies were screened by one reviewer with 10% checked by a second reviewer. The Mixed Methods Appraisal Tool was used to assess study quality. We used meta-analysis to aggregate study findings, with subgroup analyses to explore heterogeneity. RESULTS: Out of 1272 references, a total of 20 cross-sectional and 1 longitudinal studies were eligible. Older adults with frailty were substantially more likely to display anxiety symptoms than robust populations, across both dichotomous and continuous data sets (n = 10, OR = 3.48, 95% CI: 2.08, 5.81, p < 0.0001, I2  = 94%; N = 5, SMD = 3.13, 95% CI: 1.06, 5.21, I2  = 98%). Similarly, pre-frail older adults were more likely to have anxiety symptoms than robust older adults but to a lesser extent (N = 6, OR = 1.95, 95% CI: 1.41, 2.71, I2  = 63%; N = 3, SMD = 1.70, 95% CI: 0.01, 3.38, I2  = 98%). CONCLUSIONS: There is a clear association between pre-frailty/frailty and anxiety in older adults. However, data are heterogeneous and primarily from cross-sectional studies so causality cannot be determined. Future research should evaluate the effectiveness of anxiety screening and treatments in frail older adults.

[Association of sleep duration and risk of frailty among the elderly over 80 years old in China: a prospective cohort study].

Objective: To explore the association between sleep duration and the risk of frailty among the elderly over 80 years old in China. Methods: Using the data from five surveys of the China Elderly Health Influencing Factors Follow-up Survey (CLHLS) (2005, 2008-2009, 2011-2012, 2014, and 2017-2018), 7 024 elderly people aged 80 years and above were selected as the study subjects. Questionnaires and physical examinations were used to collect information on sleep time, general demographic characteristics, functional status, physical signs, and illness. The frailty state was evaluated based on a frailty index that included 39 variables. The Cox proportional risk regression model was used to analyze the correlation between sleep time and the risk of frailty occurrence. A restricted cubic spline function was used to analyze the dose-response relationship between sleep time and the risk of frailty occurrence. The likelihood ratio test was used to analyze the interaction between age, gender, sleep quality, cognitive impairment, and sleep duration. Results: The age M (Q1, Q3) of 7 024 subjects was 87 (82, 92) years old, with a total of 3 435 (48.9%) patients experiencing frailty. The results of restricted cubic spline function analysis showed that there was an approximate U-shaped relationship between sleep time and the risk of frailty. When sleep time was 6.5-8.5 hours, the elderly had the lowest risk of frailty; Multivariate Cox proportional risk regression model analysis showed that compared to 6.5-8.5 hours of sleep, long sleep duration (>8.5 hours) increased the risk of frailty by 13% (HR: 1.13; 95%CI: 1.04-1.22). Conclusion: There is a nonlinear association between sleep time and the risk of frailty in the elderly.

[Association of hs-CRP with frailty and its components among the elderly over 65 years old in 9 longevity areas of China].

Objective: To investigate the association of the levels of high sensitivity C-reactive protein (hs-CRP) with frailty and its components among the elderly over 65 years old in 9 longevity areas of China. Methods: Cross-sectional data from the Health Ageing and Biomarkers Cohort Study (HABCS, 2017-2018) were used and the elderly over 65 years old were included in this study. Through questionnaire interview and physical examination, the information including demographic characteristics, behavior, diet, daily activity, cognitive function, and health status was collected. The association between hs-CRP and frailty and its components in the participants was analyzed by multivariate logistic regression model and restrictive cubic spline. Results: A total of 2 453 participants were finally included, the age was (84.8±19.8) years old. The median hs-CRP level was 1.13 mg/L and the prevalence of frailty was 24.4%. Compared with the low-level group (hs-CRP<1.0 mg/L), the OR (95%CI) value of the high-level group (hs-CRP>3.0 mg/L) was 1.79 (1.35-2.36) mg/L. As for the components, the hs-CRP level was also positively associated with ADL disability, IADL disability, functional limitation and multimorbidity. After adjusting for confounding factors, compared with the low-level group, the OR (95%CI) values of the high-level group for the four components were 1.68 (1.25-2.27), 1.88 (1.42-2.50), 1.68 (1.31-2.14) and 1.39 (1.12-1.72), respectively. Conclusion: There is a positive association between the levels of hs-CRP and the risk of frailty among the elderly over 65 years old in 9 longevity areas of China. The higher hs-CRP level may increase the risk of frailty by elevating the risk of four physical functional disabilities, namely ADL disability, IADL disability, functional limitation and multimorbidity.

[COVID-19, neuroCOVID-19 and cognitive impairment in elderly and old patients (literature review).]

The new coronavirus infection COVID-19 causes damage to many organs and systems, is a multi-organ disease. Many researchers are studying the relationship of the new coronavirus infection with polymorbid pathology, frailty, sarcopenia. The SARS-CoV-2 virus has the property of neurotropism, therefore, olfactory, taste disorders, as well as cognitive impairments can join the spectrum of clinical manifestations and consequences of the disease. Alzheimer's disease is the most common cause of dementia in the world. It is of interest that there is a link between the coronavirus infection and the development of cognitive impairment, including Alzheimer's disease.

Association of kidney function and albuminuria with frailty worsening and death in very old adults.

BACKGROUND AND OBJECTIVES: Studies analysing the association of albuminuria and prevalent frailty in community-dwelling very old adults are scarce and lack information on incident frailty. We investigated the association of kidney function decline and increase of albuminuria with frailty worsening or death in very old adults. DESIGN: Longitudinal analyses with biennial visits of the Berlin Initiative (cohort) Study and a frailty follow-up of 2.1 years. SETTING/SUBJECTS: 1,076 participants with a mean age of 84.3 (5.6) years of whom 54% were female. METHODS: Partial proportional odds models were used to assess the association of estimated glomerular filtration rate (eGFR) decline and/or albuminuria (albumin creatinine ratio, ACR) with frailty worsening or death. RESULTS: At frailty baseline, 1,076 participants with an eGFR of 50 (13) ml/min/1.73 m2, 48% being prefrail and 31% frail were included. After median 2.1 years, 960 (90%) participants had valid information on frailty transition: 187 (17.5%) worsened and 111 (10.3%) died. In the multivariable model, the odds of frailty worsening for participants with albuminuria in combination with eGFR <60 ml/min/1.73 m2 were elevated [OR (95% CI): 2.47 (1.41-4.31)] compared to participants without albuminuria and eGFR ≥60 ml/min/1.73 m2 as there was a rapid eGFR decline of ≥3 ml/min/1.73 m2 per year [1.55 (1.04-2.33)] and albuminuria trajectories six years prior [1.53 (1.11-2.10)] to frailty baseline. The odds of death for each exposure were even higher. CONCLUSIONS: In older adults, advanced stages of CKD and albuminuria alone were associated with 2-fold odds of frailty worsening independent of death.

[The concept and practical management of frailty in neurology]. / Concepto y manejo práctico de la fragilidad en neurología.

Frailty is a clinical situation of decreased homeostatic reserve that, after a minor trigger (acute illness, fall, taking a drug...) increases the risk of an adverse event such as hospital admission, institutionalization, functional and/or cognitive decline, death, etc. Frailty can be understood as physical frailty, Fried's phenotype, a true geriatric syndrome that can be reversible by avoiding its progression to more advanced stages of irreversibility and dependence, and Rockwood's frailty due to accumulation of deficits, as a continuum of health or classification typology of the elderly along the frailty spectrum (healthy, robust, vulnerable, mild-moderate-severe and extreme frailty or end of life). The diagnosis of physical frailty is part of the comprehensive geriatric assessment, recommending the use of a performance test such as gait speed (<0,8m/s), Timed Up and Go (>12 s) or Short Physical Performance Battery (<10). Physical frailty is reversible by a multidisciplinary management based on three fundamental pillars: multicomponent physical exercise and resistance training, adequate protein and micronutrient intake (leucine, vitamin D, etc.) and appropriate pharmacological prescription, management of comorbidity and geriatric syndromes. Frailty is a risk factor for neurological disease progression and increased risk of adverse events in neurodegenerative diseases such as mild cognitive impairment, dementia, Parkinson's disease and cerebrovascular disease. Frailty based on the Clinical Frailty Scale or VIG-Frail shows patient typologies in relation to a greater or lesser state of fragility, being a basic prognostic tool of great utility in making diagnostic and therapeutic management decisions. It opens up a new opportunity for improvement in the management of neurological disease in the diagnosis and treatment of frailty.

TITLE: Concepto y manejo práctico de la fragilidad en neurología.La fragilidad se entiende como un situación clínica de disminución de la reserva homeostática que, ante un desencadenante (enfermedad aguda, caída, toma de un fármaco...), aumenta el riesgo de un evento adverso, como ingreso hospitalario, en residencia, deterioro funcional y/o cognitivo, muerte, etc. La fragilidad puede entenderse como fragilidad física, fenotipo de Fried, verdadero síndrome geriátrico, que puede ser reversible evitando su progresión a estadios más avanzados de irreversibilidad y de dependencia, y fragilidad por acúmulo de déficits de Rockwood, como continuum de salud o tipología de clasificación del anciano a lo largo del espectro de la fragilidad (sano, robusto, vulnerable, fragilidad leve-moderada-grave y extrema o final de vida). El diagnóstico de fragilidad física forma parte de la valoración geriátrica integral y se recomienda para su diagnóstico utilizar un test de ejecución, como velocidad de la marcha (menor de 0,8 m/s), Timed Up and Go (>12 segundos) o Short Physical Performance Battery (menor de 10). La fragilidad física es reversible basándose en un tratamiento multidisciplinar sobre tres pilares fundamentales: ejercicio físico multicompetente y contra resistencia, aporte adecuado de proteínas y micronutrientes (leucina, vitamina D, etc.), y adecuada prescripción farmacológica, de tratamiento de comorbilidad y de síndromes geriátricos. La fragilidad es un factor de riesgo de progresión de la enfermedad neurológica y de mayor riesgo de evento adverso tanto en enfermedades neurodegenerativas, como el deterioro cognitivo leve, la demencia o la enfermedad de Parkinson, como en la enfermedad cerebrovascular. La fragilidad a través de la Clinical Frailty Scale o el VIG-Frail muestra tipologías de pacientes en relación con un mayor o menor estado de fragilidad, y es una herramienta básica pronóstica de gran utilidad en la toma de decisiones de manejo diagnóstico y terapéutico. Se abre una nueva oportunidad de mejora en el manejo de la enfermedad neurológica ante el diagnóstico y el tratamiento de la fragilidad.

Rational Prescribing and Deprescribing of Antihypertensive Medications in Older People, a Three-Part Narrative Review, Part 3.

What happens when you stop? This is the third of a three-part series on antihypertensive medication use in older people. In the first, we reviewed the importance of better blood pressure (BP) control, even in older people with hypertension. In the second, we discussed the limitations of the evidence favoring intensive therapy for some older people. For older people with advanced frailty or those with a limited life expectancy, medications taken for BP can actually be a source of morbidity. Guidelines encourage clinical judgment and rational prescribing. Sometimes the best action is to stop prescribing. De-prescribing of medical therapy is now considered good practice for a range of medications for suitable patients; should this include antihypertensives? In part three of this three-part series, we will review some of the evidence available thus far, demonstrating de-intensification of antihypertensive medications is not a new idea. We will offer a guide to identifying the most suitable patients for de-prescribing: cognitive impairment, frailty, when circumstances change, or when BP is (too) well-controlled. This is an area of equipoise and needs more research. There is a path forward that we hope to illuminate.

Biomass fuel usage for cooking and frailty among older adults in China: a population-based cohort study.

Background: Although outdoor air pollution is reported to have a negative effect on frailty, evidence involving household air pollution is sparse. Methods: A cohort study on older participants aged ≥65 years from the Chinese Longitudinal Healthy Longevity Survey was conducted between 2011/2012 and 2014. Household cooking fuel types were determined by self-reported questionaries, and were dichotomized into clean or biomass fuels. The frailty status was evaluated via a 46-item frailty index (FI) and the FRAIL scale, respectively. Frailty was identified if FI >0.21 or FRAIL score ≥3. Cox proportional hazards models were employed to examine the relationship between cooking fuels and incident frailty. And the effects of swapping cooking fuels on frailty risk were also explored. Results: Among 4,643 participants (mean age at baseline 80.9 ± 9.6 years, 53.7% male) totaling 11,340 person-years, 923 (19.9%) incident frailty was identified using FI. Compared to clean fuels, cooking with biomass fuels was intricately linked to a 23% rise in frailty risk (hazard ratio [HR] 1.23, 95% confidence interval [CI] 1.06-1.43). A similar association was detected between biomass cooking fuels and frailty measured by the FRAIL scale (HR 1.24, 95% CI 1.04-1.50). Sensitive analyses supported the independent relationship between biomass fuels and frailty. Stratified analyses revealed that the frailty risk was higher among town residents (HR 1.44, 95% CI 1.13-1.84) and participants not exercising regularly (HR 1.35, 95% CI 1.11-1.64). In comparison with persistent biomass fuels usage, switching to clean fuels had a trend to reduce the frailty risk, and the opposite effect was observed when swapping from clean to biomass fuels. Conclusion: Cooking with biomass fuels was associated with an increased frailty risk in older adults, especially amongst those living in town and those lacking regular exercise. More studies are needed to confirm our findings and to evaluate the potential benefits of reducing indoor biomass fuel usage.

Geriatric Trauma and Frailty: Improving Outcomes Through Multidisciplinary Care.

Geriatric trauma is increasing in the United States. The care of patients with geriatric trauma is complex due to age-related changes and comorbidities. Patients with geriatric trauma have increased risk of poor outcomes compared with younger patients with trauma, and the highest risk groups are those who have frailty. These patients require special care considerations. Multidisciplinary care can improve outcomes in frail patients with geriatric trauma.
