Muscle mass loss measured with portable ultrasound in hospitalized older adults: The ECOSARC study.

OBJECTIVES: The main objective was to analyze the evolution of muscle of the Quadriceps Rectus Femoris (QRF) between admission and discharge, in older adults hospitalized with an acute medical disease in Acute Geriatric Units (AGUs). DESIGN: Prospective multicentric observational cohort study. SETTING: Seven AGUs from University Hospitals in Spain. PARTICIPANTS: Hospitalized adults ≥ 70 years old, able to ambulate and without severe dementia. MEASUREMENTS: Ultrasound measurements of QRF were acquired at 2/3 distal between anterior-superior iliac spine and patella in both legs by trained Geriatricians. Ultrasound Chison model ECO2 was used. QRF area, thickness, edema, echogenicity, and fasciculations were measured. RESULTS: From the complete sample (n = 143), in 45 (31.5%) participants, ultrasound images were classified as non-valid by an expert radiologist. Mean age was 87.8 (SD 5.4). Mean hospital stay 7.6 days (SD 4.3). From those with valid images, 36 (49.3%), 2 (2.7%), and 35 (47.9%) presented a decrease, equal values, or an increase in QRF area from baseline to discharge, respectively, and 37 (50.0%), 2 (2.7%), and 35 (47.3%) presented a decrease, equal values, or an increase in QRF thickness, respectively. 26 (35.6%) presented a decrease in more than 0.2 cm2 of QRF area, and 23 (31.1%) a decrease in more than 0.1 cm of QRF thickness. Only 4 (5.4%) patients presented new edema, while 13 (17.6%) worsened echogenicity. CONCLUSION: One third of older adults develop significant muscle loss during a hospitalization for acute medical diseases. TRIAL REGISTRATION NUMBER: NCT05113758.

"SARCOPENIA MEASURED BY ULTRASOUND IN HOSPITALIZED OLDER ADULTS" (ECOSARC): multi-centre, prospective observational study protocol.

BACKGROUND: Measurement of muscle mass and function, and thereafter, screening and diagnosis of sarcopenia, is a challenge and a need in hospitalized older adults. However, it is difficult in complex real-world old patients, because usually they are unable to collaborate with clinical, functional, and imaging testing. Ultrasound measurement of quadriceps rectus femoris (QRF) provides a non-invasive, real-time assessment of muscle quantity and quality, and is highly acceptable to participants with excellent inter-rater and intra-rater variability. However, normative data, protocol standardization, and association with longitudinal outcomes, needs further research and consensus. METHODS: Prospective exploratory multicenter study in older adults admitted to Acute Geriatric Units (AGUs) for medical reasons. 157 subjects from 7 AGUs of Spain were recruited between May 2019 and January 2022. Muscle ultrasound measurements of the anterior vastus of the QRF were acquired on admission and on discharge, using a previously validated protocol, using a Chieson model ECO2 ultrasound system (Chieson Medical Technologies, Co. Ltd, Wimxu District Wuxi, Jiangsu, China). Measurements included the cross-sectional area, muscle thickness in longitudinal view, intramuscular central tendon thickness, echogenicity, and the presence or absence of edema and fasciculations. Functional, nutritional, and DXA measurements were provided. Clinical follow-up was completed at discharge, and 30 and 90 days after discharge. Variations between hospital admission and discharge ultrasound values, and the relationship with clinical variables, will be analyzed using paired t-tests, Wilcoxon tests, or Mc Nemar chi-square tests when necessary. Prevalence of sarcopenia will be calculated, as well as sensitivity and specificity of ultrasound measurements to determine sarcopenia. Kappa analysis will be used to analyze the concordance between measurements, and sensitivity analysis will be conducted for each participating center. DISCUSSION: The results obtained will be of great interest to the scientific geriatric community to assess the utility and validity of ultrasound measurements for the detection and follow-up of sarcopenia in hospitalized older adults, and its association with adverse outcomes. TRIAL REGISTRATION: NCT05113758. Registration date: November 9th 2021. Retrospectively registered.

Resting metabolic rate in relation to incident disability and mobility decline among older adults: the modifying role of frailty.

BACKGROUND: Alterations in resting metabolic rate (RMR), the largest component of daily total energy expenditure, with aging have been shown in various studies. However, little is known about the associations between RMR and health outcomes in later life. AIMS: To analyze whether RMR is associated with incident disability and mobility decline in a 10-year longitudinal study, as well as the moderating role of frailty in these associations. METHODS: Data from 298 older adults aged 70 and over from the Frailty and Dependence in Albacete (FRADEA) study in Spain were used, including a baseline measurement in 2007-2009 and a follow-up measurement 10 years later. RMR was measured by indirect calorimetry. Outcomes were incident disability in basic activities of daily living (BADL, Barthel Index), incident disability in instrumental ADL (IADL, Lawton index), and mobility decline (Functional Ambulation Categories scores). Fried's frailty phenotype was used as an indicator of frailty. Logistic regression analyses were conducted. RESULTS: Fully adjusted and stratified analyses revealed that only in the pre-frail/frail group, a higher RMR was associated with a lower risk of incident BADL disability (OR = 0.47, 95% CI = 0.23-0.96, p = 0.037), incident IADL disability (OR = 0.39, 95% CI = 0.18-0.84, p = 0.017), and mobility decline (OR = 0.30, 95% CI = 0.14-0.64, p = 0.002). CONCLUSIONS: To our knowledge, this is the first study looking at the associations between RMR and functional health using a longitudinal research design. The results suggest that RMR could be used as an early identifier of a specific resilient group within the pre-frail and frail older population, with a lower risk of further health decline.

Limits of stability and falls during a multicomponent exercise program in faller older adults: A retrospective cohort study.

BACKGROUND/OBJETIVES: Multicomponent exercise programs have been demonstrated to prevent falls in older adults. However, the underlying responsible mechanisms are not clear. We aimed to analyze the association between changes in the limits of stability (LOS) as a relevant balance component, and falls occurrence during a multicomponent physical exercise program. METHODS: Retrospective study, including ninety-one participants who had experienced a fall in the previous year, and were attended in a falls unit. All of them were included in a twice-a-week multicomponent exercise program during 16 weeks. Pre- and post-program measurements were collected for leg press, gait speed, the short physical performance battery (SPPB), and LOS (point of excursion [POE] and maximal excursion [MEX]) with posturography. Falls occurrence was assessed between the beginning and the completion of the exercise program (16 week). RESULTS: The mean age was 77.2 years, and 72 were female. Thirty-two participants fell at least once during the exercise period. The global baseline POE was 47.6 %, and the MEX was 64.7 %, and there were no differences between fallers and nonfallers. Nonfallers presented greater improvements in POE (6.3 % versus 1.3 %; p < .05) and MEX (9.2 % versus 3.0 %; p < .01) than fallers. The POE and MEX were independently associated with a reduced probability of having had a fall, OR: 0.95 (95 % CI: 0.91 to 0.99) and 0.94 (95 % CI: 0.90 to 0.99), respectively. Changes in SPPB results or leg press strength were not associated with decreased falls. Adjusted probability of fall occurrence decreased by 5 % and 6 % per 1 % improvement in absolute values in POE and MEX, respectively. CONCLUSIONS: Improvements in LOS after a multicomponent physical exercise program in older adults with previous falls may be associated with a decreased occurrence of falls.

Frailty, depression risk and 10-year hospitalization in older adults. The FRADEA study.

OBJECTIVES: To determine whether the interaction between frailty status and depression risk is associated with hospitalization density in older adults. METHODS: Ongoing cohort study in 794 subjects aged over 70 years from Albacete (Spain). Data were collected on depression risk, frailty, hospitalizations, and covariates. Participants were categorized into six groups. RESULTS: Adjusted hospitalization risk was higher for groups of prefrail/-non depression risk (HR 1.48; 95% confidence interval (CI) 1.16-1.89), prefrail/depression risk (HR 1.73; 95% CI 1.29-2.30), frail/non depression risk (HR 1.79; 95% CI 1.22-2.62), and frail/depression risk (HR 2.12; 95% CI 1.49-3.02), compared with robust/non depression risk group (p<0.01). Frail and prefrail groups presented increased hospitalization density in the first four follow-up years. CONCLUSIONS: Depression risk changes the yearly probabilities of hospitalization in prefrail and frail groups, increasing them in the first years. Depression risk should be monitored in prefrail and frail older adults as an independent risk factor for hospitalization.

Psychological and Functional Impact of COVID-19 in Long-Term Care Facilities: The COVID-A Study.

OBJECTIVE: To analyze the psychological and functional sequelae of the COVID-19 pandemic among older adults living in long term care facilities (LTCFs). DESIGN: Cohort longitudinal study SETTING ANT PARTICIPANTS: A total of 215 residents ≥ 65 years without moderate-to-severe cognitive impairment, living in five LTCFs in Albacete (Spain). MEASUREMENTS: Baseline on-site data were collected between March - June 2020 and three-month follow-up between June to September 2020. Symptoms of depression, anxiety, posttraumatic stress disorder (PTSD), and sleep disturbances were measured as psychological variables. Disability in basic activities of daily living (BADL), ambulation and frailty were assessed as functional variables. Differences were analyzed in relation to level of comorbidity and test positivity for COVID-19. RESULTS: At baseline, residents with COVID-19 presented worse functionality, higher frailty levels and malnutrition risk compared to non-COVID-19 residents. At three-month follow-up, higher rates of clinically significant depressive symptoms (57.7%), anxiety symptoms (29.3%), PTSD symptoms (19.1%) and sleep disturbances (93.0%) were found among residents regardless of COVID status. Thus, among 215 residents, 101 (47%) experienced a decline in BADL from baseline to the 3-month follow-up (median functional loss = 5 points in Barthel Index). In multivariate analyses, COVID-19 status did not explain either the functional or the ambulation loss. By contrast, residents with low comorbidity and COVID-19 presented higher PTSD symptoms (effect 2.58; 95% CI 0.93 to 4.23) and anxiety symptoms (effect 2.10; 95% CI 0.48 to 3.73) compared to the low comorbidity/non-COVID19 group. CONCLUSION: COVID-19 pandemic was associated, after three-months, with high psychological impact in older adults in LTCFs., specifically with higher post-traumatic stress and anxiety symptoms. Functional decline did not differ in relation to COVID-19 status but could be related to isolation strategies used for pandemic control.

Immunogenicity after 6 months of BNT162b2 vaccination in frail or disabled nursing home residents: The COVID-A Study.

BACKGROUND: There is incomplete information regarding evolution of antibody titers against SARS-CoV-2 after a two-dose strategy vaccination with BNT162b2 in older adults in long-term care facilities (LTCFs) with frailty, disability, or cognitive impairment. We aimed to determine IgG antibody titer loss in older adults in LTCFs. METHODS: This is a multicenter longitudinal cohort study including 127 residents (90 females and 37 males) with a mean age of 82.7 years (range 65-99) with different frailty and disability profiles in two LTCFs in Albacete, Spain. Residents received two doses of BNT162b2 as per label, and antibody levels were determined 1 and 6 months after the second dose. Age, sex, previous history of coronavirus disease 2019 (COVID-19), comorbidity (Charlson Index), performance in activities of daily living (Barthel Index), frailty (FRAIL instrument), and cognitive status were assessed. RESULTS: The mean antibody titers 1 and 6 months after the second vaccine dose were 32,145 AU/ml (SD 41,206) and 6182 AU/ml (SD 13,316), respectively. Across all participants, the median antibody titer loss measured 77.6% (interquartile range [IQR] 23.8%). Notably, the decline of titers in individuals with pre-vaccination COVID-19 infection was significantly lower than in those without a history of SARS-CoV-2 infection (72.2% vs. 85.3%; p < 0.001). The median titer decrease per follow-up day was 0.47% (IQR 0.14%) and only pre-vaccination COVID-19 was associated with lower rate of antibody decline at 6 months (hazard ratio 0.17; 95% confidence interval 0.07-0.41; p < 0.001). Frailty, disability, older age, cognitive impairment, or comorbidity were not associated with the extent of antibody loss. CONCLUSIONS: Older adults in LTCFs experience a rapid loss of antibodies over the first 6 months after the second dose of BNT162b2 vaccine. Only pre-vaccination COVID-19 is associated with a slower rate of antibody decrease. Our data support immunization with a third dose in this vulnerable, high-risk population.

Baricitinib reduces 30-day mortality in older adults with moderate-to-severe COVID-19 pneumonia.

BACKGROUND: Older adults are at the highest risk of severe disease and death due to COVID-19. Randomized data have shown that baricitinib improves outcomes in these patients, but focused stratified analyses of geriatric cohorts are lacking. Our objective was to analyze the efficacy of baricitinib in older adults with COVID-19 moderate-to-severe pneumonia. METHODS: This is a propensity score [PS]-matched retrospective cohort study. Patients from the COVID-AGE and Alba-Score cohorts, hospitalized for moderate-to-severe COVID-19 pneumonia, were categorized in two age brackets of age <70 years old (86 with baricitinib and 86 PS-matched controls) or ≥70 years old (78 on baricitinib and 78 PS-matched controls). Thirty-day mortality rates were analyzed with Kaplan-Meier and Cox proportional hazard models. RESULTS: Mean age was 79.1 for those ≥70 years and 58.9 for those <70. Exactly 29.6% were female. Treatment with baricitinib resulted in a significant reduction in death from any cause by 48% in patients aged 70 or older, an 18.5% reduction in 30-day absolute mortality risk (n/N: 16/78 [20.5%] baricitinib, 30/78 [38.5%] in PS-matched controls, p < 0.001) and a lower 30-day adjusted fatality rate (HR 0.21; 95% CI 0.09-0.47; p < 0.001). Beneficial effects on mortality were also observed in the age group <70 (8.1% reduction in 30-day absolute mortality risk; HR 0.14; 95% CI 0.03-0.64; p = 0.011). CONCLUSIONS: Baricitinib is associated with an absolute mortality risk reduction of 18.5% in adults older than 70 years hospitalized with COVID-19 pneumonia.

Immunogenicity of the BNT162b2 vaccine in frail or disabled nursing home residents: COVID-A study.

BACKGROUND/OBJECTIVES: The safety and immunogenicity of the BNT162b2 coronavirus disease 2019 (COVID-19) vaccine in older adults with different frailty and disability profiles have not been well determined. Our objective was to analyze immunogenicity of the BNT162b2 mRNA COVID-19 vaccine in older adults across frailty and disability profiles. DESIGN: Multicenter longitudinal cohort study. SETTING AND PARTICIPANTS: A total of 134 residents aged ≥65 years with different frailty and disability profiles in five long-term care facilities (LTCFs) in Albacete, Spain. INTERVENTION AND MEASUREMENTS: Residents were administered two vaccine doses as per the label, and antibody levels were determined 21.9 days (SD 9.3) after both the first and second dose. Functional variables were assessed using activities of daily living (Barthel Index), and frailty status was determined with the FRAIL instrument. Cognitive status and comorbidity were also evaluated. RESULTS: Mean age was 82.9 years (range 65-99), and 71.6% were female. The mean antibody titers in residents with and without previous COVID-19 infection were 49,878 AU/ml and 15,274 AU/ml, respectively (mean difference 34,604; 95% confidence interval [CI]: 27,699-41,509). No severe adverse reactions were observed, after either vaccine dose. Those with prevaccination COVID-19 had an increased antibody level after the vaccine (B = 31,337; 95% CI: 22,725-39,950; p < 0.001). Frailty, disability, older age, sex, cognitive impairment, or comorbidities were not associated with different antibody titers. CONCLUSIONS: The BNT162b2 mRNA COVID-19 vaccine in older adults is safe and produces immunogenicity, independently of the frailty and disability profiles. Older adults in LTCFs should receive a COVID-19 vaccine.

The Functional Continuum Scale in Relation to Hospitalization Density in Older Adults: The FRADEA Study.

BACKGROUND: There is a need to know the relationship between function and hospitalization risk in older adults. We aimed at investigating whether the Functional Continuum Scale (FCS), based on basic (BADL) and instrumental (IADL) activities of daily living and frailty, is associated with hospitalization density in older adults across 12 years of follow-up. METHODS: Cohort study, with a follow-up of 12 years. A total of 915 participants aged 70 years and older from the Frailty and Dependence in Albacete (FRADEA) study, a population-based study in Spain, were included. At baseline, the FCS, sociodemographic characteristics, comorbidity, number of medications, and place of residence were assessed. Associations with first hospitalization, number of hospitalizations, and 12-year density of hospitalizations were assessed using Kaplan-Meier curves, Poisson regression analyses, and density models. RESULTS: The median time until the first hospitalization was shorter toward the less functionally independent end of the FCS, from 3917 days (95% confidence interval [CI] 3701-3995) to 1056 days (95% CI 785-1645) (p < .001). The incidence rate ratio (IRR) for all hospitalizations increased from the robust category until the frail one (IRR 1.89), and thereafter it decreased until the worse functional category. Those who were BADL dependent presented an increased hospitalization density in the first 4 follow-up years (58%), those who were frail in the third-to-sixth follow-up years (55%), while in those prefrail or robust the hospitalization density was homogeneous during the complete follow-up. CONCLUSIONS: The FCS is useful for stratifying the risk of hospitalization and for predicting the density of hospitalizations in older adults.

COVID-19 outbreak in long-term care facilities from Spain. Many lessons to learn.

BACKGROUND/OBJECTIVES: To analyze mortality, costs, residents and personnel characteristics, in six long-term care facilities (LTCF) during the outbreak of COVID-19 in Spain. DESIGN: Epidemiological study. SETTING: Six open LTCFs in Albacete (Spain). PARTICIPANTS: 198 residents and 190 workers from LTCF A were included, between 2020 March 6 and April 5. Epidemiological data were also collected from six LTCFs of Albacete for the same period of time, including 1,084 residents. MEASUREMENTS: Baseline demographic, clinical, functional, cognitive and nutritional variables were collected. 1-month and 3-month mortality was determined, excess mortality was calculated, and costs associated with the pandemics were analyzed. RESULTS: The pooled mortality rate for the first month and first three months of the outbreak were 15.3% and 28.0%, and the pooled excess mortality for these periods were 564% and 315% respectively. In facility A, the percentage of probable COVID-19 infected residents were 33.6%. Probable infected patients were older, frail, and with a worse functional situation than those without COVID-19. The most common symptoms were fever, cough and dyspnea. 25 residents were transferred to the emergency department, 21 were hospitalized, and 54 were moved to the facility medical unit. Mortality was higher upon male older residents, with worse functionality, and higher comorbidity. During the first month of the outbreak, 65 (24.6%) workers leaved, mainly with COVID-19 symptoms, and 69 new workers were contracted. The mean number of days of leave was 19.2. Costs associated with the COVID-19 in facility A were estimated at € 276,281/month, mostly caused by resident hospitalizations, leaves of workers, staff replacement, and interventions of healthcare professionals. CONCLUSION: The COVID-19 pandemic posed residents at high mortality risk, mainly in those older, frail and with worse functional status. Personal and economic costs were high.

Potential early biomarkers of sarcopenia among independent older adults.

OBJECTIVES: There are no tools or biomarkers for a quantitative analysis of sarcopenia. STUDY DESIGN: Cross-sectional study of the diagnosis of sarcopenia in 200 independent adults aged 70 years or over. MAIN OUTCOME MEASURES: Sarcopenia was defined as loss of muscle mass together with low strength and/or loss of physical performance. We considered different clinical parameters and assayed potential blood biomarkers (cell energetic metabolism, muscle performance, inflammation, infection and oxidative stress). RESULTS: The prevalence of sarcopenia was 35.3% in women and 13.1% in men, and it was significantly associated with advanced age, a low functional performance in the lower extremities, deficient weekly consumption of kilocalories, risk of malnutrition, and drug use for the digestive system. A close relationship was found between sarcopenia, pre-frailty and depressed mood. With these confounding variables, we observed that products of lipid peroxidation were closely associated with sarcopenia in independent older adults (frail participants and those with severe dependence had been excluded from the sample). The best multivariate model proposed was able to predict 67.6% of the variance in sarcopenia, with a power of discrimination of 93.5%. Additional analyses considering lipid levels, fat mass, dyslipidemia, use of lipid-lowering drugs and hypertension confirmed this close association between lipid peroxidation and sarcopenia. CONCLUSIONS: Given the difficulty in the diagnosis of sarcopenia in clinical practice, we suggest the use of blood circulating products of lipid peroxidation as potential biomarkers for an early diagnosis of sarcopenia in independent older adults.

Introducción. El objetivo de nuestro trabajo fue analizar si la fragilidad se asocia a largo plazo con mortalidad, discapacidad incidente en actividades básicas de la vida diaria (ABVD) y hospitalización. Material y métodos. Estudio de cohortes concurrente sobre 993 mayores de 70 años incluidos en el estudio FRADEA. La fragilidad se midió mediante el fenotipo de Fried. Durante el seguimiento se registraron mortalidad, hospitalización y discapacidad incidente en ABVD (baño, aseo, vestido, retrete, transferencias y comer). El riesgo de presentar dichos eventos adversos se determinó mediante regresión logística, Kaplan-Meier y análisis de riesgos proporcionales de Cox ajustado por edad, sexo, Barthel basal, comorbilidad e institucionalización. Resultados. El tiempo medio de seguimiento fue de 952 días (DE 408) durante los cuales fallecieron 182 sujetos (18,4%). Los participantes frágiles tuvieron mayor riesgo ajustado de mortalidad (HR 4,5; IC 95%: 1,8-11,1), discapacidad incidente en ABVD (OR 2,7; IC 95%: 1,3-5,9) y del evento combinado mortalidad o discapacidad incidente (OR 3,0; IC 95%: 1,5-6,1). Los prefrágiles tuvieron mayor riesgo ajustado de mortalidad (HR 2,9; IC 95%: 1,2-6,5), discapacidad incidente (OR 2,1; IC 95%: 1,2-3,6) y del evento combinado mortalidad o discapacidad incidente (OR 2,2; IC 95%: 1,3-3,6). Se observó una asociación positiva entre fragilidad y hospitalización que quedó al borde de la significación (OR 1,7; IC 95%: 1,0-3,0). Conclusiones. El estado de fragilidad se asocia a largo plazo con mortalidad y discapacidad incidente en ABVD en una cohorte de ancianos españoles (AU)

Introduction. The objective of this study was to analyse whether frailty is related to long-term mortality, incident disability in basic activities of daily living (BADL), and hospitalisation. Material and methods. A concurrent cohort study conducted on 993 participants over age 70 from the FRADEA Study. Frailty was determined with Fried frailty phenotype. Data was collected on mortality, hospitalisation and incident disability in BADL (bathing, grooming, dressing, toileting, eating or transferring) during the follow-up period. The risk of adverse events was determined by logistic regression, Kaplan-Meier analysis, and Cox proportional hazard analysis adjusted for age, sex, Barthel index, comorbidity and institutionalization. Results. Mean follow-up was 952 days (SD 408), during which 182 participants (18.4%) died. Frail participants had an increased adjusted risk of death (HR 4.5, 95%CI: 1.8-11.1), incident disability in BADL (OR 2.7, 95%CI: 1.3-5.9) and the combined event mortality or incident disability (OR 3.0, 95%CI: 1.5-6.1). Pre-frail subjects had an increased adjusted risk of death (HR 2.9, 95%CI: 1.2-6.5), incident disability in BADL (OR 2.1, 95%CI: 1.2-3.6), and the combined event mortality or incident disability (OR 2.2, 95%CI: 1.3-3.6). There was a positive association between frailty and hospitalisation, which almost reached statistical significance (OR 1.7, 95%CI: 1.0-3.0). Conclusions. Frailty is long-term associated with mortality and incident disability in BADL in a Spanish cohort of older adults (AU)

Enfermedad crónica, mortalidad, discapacidad y pérdida de movilidad en ancianos españoles: estudio FRADEA / Chronic disease, mortality and disability in an elderly Spanish population: The FRADEA study

Introducción: El objetivo de nuestro trabajo fue analizar la asociación entre las principales enfermedades crónicas y la multimorbilidad, con mortalidad, discapacidad incidente en actividades básicas de la vida diaria y pérdida de movilidad en ancianos. Material y métodos: Novecientos cuarenta y tres participantes del estudio FRADEA con datos en la visita basal de enfermedades crónicas, y en la segunda visita de mortalidad, discapacidad incidente y pérdida de movilidad. Se analizó la asociación cruda y ajustada por edad, sexo y discapacidad previa entre el recuento de enfermedades crónicas total, el recuento de 14 enfermedades prevalentes preseleccionadas y la presencia de 2 o más de estas últimas (multimorbilidad) con los eventos adversos de salud referidos. Resultados: Los participantes con mayor recuento de enfermedades totales (OR 1,11; IC 95% 1,02-1,22), así como seleccionadas (OR 1,19; IC95% 1,03-1,38) tuvieron un mayor riesgo ajustado de mortalidad, pero no de discapacidad incidente ni pérdida de movilidad. Los sujetos con multimorbilidad tuvieron mayor riesgo ajustado, aunque no significativo, de mortalidad (HR 1,45; IC95% 0,87-2,43), frente a los que no la tenían. El tiempo medio libre de discapacidad incidente en participantes sin y conmultimorbilidad fue de 846 ± 34 y 731 ± 17 días respectivamente (log-rank 2 7,45; p = 0,006), y sin y con pérdida de movilidad fue de 818 ± 32 y 696 ± 13 días respectivamente (log-rank 2 10,99; p = 0,001). Conclusiones: La multimorbilidad no se asocia de manera ajustada con mortalidad, discapacidad incidente ni pérdida de movilidad en mayores de 70 años, aunque sí con mortalidad si se considera el recuento de enfermedades crónicas de manera lineal (AU)

Introduction: The objective of this study was to analyse the relationships between the major chronic diseases and multiple morbidity, with mortality, incident disability in basic activities of daily living, and loss of mobility in the elderly. Material and methods: A total of 943 participants were selected from the FRADEA Study, using available baseline data of chronic diseases, and at the follow-up visit of mortality, incident disability, and loss of mobility. The analysis was made of the unadjusted and adjusted association between the number of chronic diseases, the number of 14 pre-selected diseases, and the presence of two or more chronic diseases (multiple morbidity) with adverse health events recorded. Results: Participants with a higher number of diseases (OR 1.11; 95% CI: 1.02-1.22), and 14 preselected diseases (OR 1.19; 95% CI: 1.03-1.38) had a higher adjusted mortality risk, but not a higher incident disease or mobility loss risk. Subjects with multiple morbidity had a higher non-significant mortality risk (HR 1.45; 95% CI: 0.87-2.43), than those without multiple morbidity. Disability-free mean time in participants with and without multiple morbidity was 846 ± 34 and 731 ± 17 days, respectively (Log-rank 2 7.45. P =.006), and with our without mobility loss was 818±32 and 696±13 days, respectively (Log rank 2 10.99. P =.001). Conclusions: Multiple morbidity was not associated with mortality, incident disability in ADL, or mobility loss in adults older than 70 years, although if mortality is taken into account, the number of chronic diseases is linear (AU)

INTRODUCTION: The objective of this study was to analyse the relationships between the major chronic diseases and multiple morbidity, with mortality, incident disability in basic activities of daily living, and loss of mobility in the elderly. MATERIAL AND METHODS: A total of 943 participants were selected from the FRADEA Study, using available baseline data of chronic diseases, and at the follow-up visit of mortality, incident disability, and loss of mobility. The analysis was made of the unadjusted and adjusted association between the number of chronic diseases, the number of 14 pre-selected diseases, and the presence of two or more chronic diseases (multiple morbidity) with adverse health events recorded. RESULTS: Participants with a higher number of diseases (OR 1.11; 95% CI: 1.02-1.22), and 14 pre-selected diseases (OR 1.19; 95% CI: 1.03-1.38) had a higher adjusted mortality risk, but not a higher incident disease or mobility loss risk. Subjects with multiple morbidity had a higher non-significant mortality risk (HR 1.45; 95% CI: 0.87-2.43), than those without multiple morbidity. Disability-free mean time in participants with and without multiple morbidity was 846±34 and 731±17 days, respectively (Log-rank χ(2) 7.45. P=.006), and with our without mobility loss was 818±32 and 696±13 days, respectively (Log rank χ(2) 10.99. P=.001). CONCLUSIONS: Multiple morbidity was not associated with mortality, incident disability in ADL, or mobility loss in adults older than 70 years, although if mortality is taken into account, the number of chronic diseases is linear.

Fragilidad como predictor de episodios adversos en estudios epidemiológicos: revisión de la literatura / Frailty as a predictor of adverse events in epidemiological studies: Literature review

Diversos estudios epidemiológicos han evaluado la relación entre el estado de fragilidad con episodios adversos geriátricos en salud como la mortalidad, la discapacidad, la pérdida de movilidad, la institucionalización o las caídas, demostrando una clara asociación. Sin embargo, estos episodios han sido valorados de forma heterogénea, tanto en su número, criterios empleados y tiempo de seguimiento. Esta asociación implica que el objetivo de la atención geriátrica no debe ser solo la prevención, el diagnóstico y el tratamiento de los procesos de la enfermedad mediante el trabajo multidisciplinar y el uso de niveles asistenciales adaptados a la funcionalidad del anciano, sino la detección del estado de fragilidad entendido como un síndrome previo a la discapacidad sobre el que implementar tratamientos específicos que retarden su aparición, y las consecuencias derivadas del deterioro funcional. Otro objetivo es el apoyo a otras especialidades médicas para estadificar el nivel de riesgo en circunstancias específicas como los tratamientos del cáncer, la realización de pruebas diagnósticas o las intervenciones quirúrgicas (AU)

Several epidemiological studies have analyzed the association between frailty status and adverse geriatric health outcomes, with there being a clear relationship being demonstrated in mortality, disability, mobility loss, institutionalization and falls. However, different studies have evaluated different number of these adverse events, with different criteria, and with different follow-up periods. As a result of this relationship, the objective of geriatric medicine must not only be the prevention, diagnosis and treatment of diseases based on multidisciplinary team work and use of geriatric units according to functional status of patients, but the detection, prevention and treatment of frailty. Frailty must be considered as a pre-disability state that can be prevented and treated to delay its progression towards disability, institutionalization, and death. The characterization of frailty status can also help other medical specialties to stratify the risk of adverse health outcomes in oncology treatments, surgical interventions, or diagnostic procedures (AU)

Valores normativos de instrumentos de valoración funcional en ancianos españoles: estudio FRADEA / Normal data of functional assessment tools of the elderly in Spain: The FRADEA Study

Objetivo: Determinar los valores normativos de algunos de los diferentes instrumentos de valoración funcional más usados en España. Diseño: Estudio transversal del primer corte de una cohorte concurrente de base poblacional. Emplazamiento: Área de salud de Albacete capital. Participantes: 993 sujetos con edad igual o mayor a 70 años participantes en la cohorte FRADEA. Mediciones principales: Se recogieron cuestionarios de discapacidad y función, Barthel, Lawton e Instrumento Abreviado de Discapacidad y Función en la Edad Avanzada (SF-LLFDI), escala de deambulación de Holden (FAC), y pruebas de ejecución: velocidad de marcha (m/s), levántese y ande cronometrado (TUG) (s), tiempo de equilibrio unipodal (s), sentarse y levantarse 5 veces de una silla cronometrado (5STS) (s), Short Physical Performance Battery (SPPB), fuerza prensora (kg), y fuerza flexora codo (kg). Se describen medias, cuartiles y percentiles en la cohorte global, y en los subgrupos de hombres y mujeres con edad entre 70 y 79 o igual o mayor a 80 años. Resultados: Los cuartiles de los diferentes instrumentos fueron respectivamente Barthel (80, 95, 100), Lawton (3, 6, 8), SF-LLFDI (70, 111, 131), FAC (4, 5, 5), velocidad de marcha (0,51, 0,79, 1,00), TUG (13,8, 11,4, 9,8), tiempo de equilibrio unipodal (3, 7, 15), 5STS (16,3, 13,0, 10,7), SPPB (7, 9, 11), fuerza prensora (15, 20, 29), y fuerza flexora de codo (11, 20, 32). Los más jóvenes, los hombres y los residentes en la comunidad, presentaron mejores rendimientos en todos los instrumentos. Conclusiones: Se presentan los valores normativos de diferentes instrumentos de valoración funcional de una cohorte de ancianos de Albacete de base poblacional. Éstos pueden ser útiles para su empleo en clínica o en investigación(AU)
