Development of Continuous Assessment of Muscle Quality and Frailty in Older Patients Using Multiparametric Combinations of Ultrasound and Blood Biomarkers: Protocol for the ECOFRAIL Study.

BACKGROUND: Frailty resulting from the loss of muscle quality can potentially be delayed through early detection and physical exercise interventions. There is a demand for cost-effective tools for the objective evaluation of muscle quality, in both cross-sectional and longitudinal assessments. Literature suggests that quantitative analysis of ultrasound data captures morphometric, compositional, and microstructural muscle properties, while biological assays derived from blood samples are associated with functional information. OBJECTIVE: This study aims to assess multiparametric combinations of ultrasound and blood-based biomarkers to offer a cross-sectional evaluation of the patient frailty phenotype and to track changes in muscle quality associated with supervised exercise programs. METHODS: This prospective observational multicenter study will include patients aged 70 years and older who are capable of providing informed consent. We aim to recruit 100 patients from hospital environments and 100 from primary care facilities. Each patient will undergo at least two examinations (baseline and follow-up), totaling a minimum of 400 examinations. In hospital environments, 50 patients will be measured before/after a 16-week individualized and supervised exercise program, while another 50 patients will be followed up after the same period without intervention. Primary care patients will undergo a 1-year follow-up evaluation. The primary objective is to compare cross-sectional evaluations of physical performance, functional capacity, body composition, and derived scales of sarcopenia and frailty with biomarker combinations obtained from muscle ultrasound and blood-based assays. We will analyze ultrasound raw data obtained with a point-of-care device, along with a set of biomarkers previously associated with frailty, using quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay. Additionally, we will examine the sensitivity of these biomarkers to detect short-term muscle quality changes and functional improvement after a supervised exercise intervention compared with usual care. RESULTS: At the time of manuscript submission, the enrollment of volunteers is ongoing. Recruitment started on March 1, 2022, and ends on June 30, 2024. CONCLUSIONS: The outlined study protocol will integrate portable technologies, using quantitative muscle ultrasound and blood biomarkers, to facilitate an objective cross-sectional assessment of muscle quality in both hospital and primary care settings. The primary objective is to generate data that can be used to explore associations between biomarker combinations and the cross-sectional clinical assessment of frailty and sarcopenia. Additionally, the study aims to investigate musculoskeletal changes following multicomponent physical exercise programs.

[Spanish tools of cognitive and behavior assessment of alzheimer´s disease in severe state.] / Escalas de valoración cognitiva y conductual en español para la demencia severa.

BACKGROUND: There are different scales in Spanish for cognitive and behavioral assessment of patients with severe dementia. The objective of this study was to select those scales that are more accessible, useful and with better psychometric properties, both for clinical practice and for research. METHODS: Literature review, by experts in the field, of scales of cognitive and behavioral assessment in dementia in the main scientific databases. Published in Spanish or English, excluding those not validated in Spanish. RESULTS: 11 bibliographical references were selected. Cognitive scales: Severe Impairment Battery was the one with the most cognitive areas, its abbreviated version (SIB-s) had the best internal consistency (α=0.96), Baylor Profound Mental Status Examination had very good psychometric properties with 0.99 reliability and excellent concurrent validity with Mini-Mental State Examination (r=-0.91). Severe Cognitive Impairment Profile was the only one that allowed establishing subgroups of cognitive impairment. Behavioral scales: Neuropsychiatric Inventory was the gold standard in dementias, but there was only one specific scale for severe Alzheimer's disease, the Baylor Profound Mental Status Examination behavioral subscale. CONCLUSIONS: In Spanish severe dementia, Severe Cognitive Impairment Profile and the Neuropsychiatric Inventory are the gold standard tool for cognitive assessment for research studies, and the Baylor Profound Mental Status Examination is the most useful for daily clinical practice.

En cuanto a escalas conductuales: el Neuropsychiatric Inventory era el gold standard en demencias. Solo había una escala específica para la enfermedad de Alzheimer, el Baylor Profound Mental Status Examination subescala conductual. CONCLUSIONES: En demencias severas, el Severe Cognitive Impairment Profile y el Neuropsychiatric Inventory son las herramientas más completas para estudios de investigación, y el Baylor Profound Mental Status Examination la más útil para la práctica clínica.

[Comprehensive Care Home Unit: reduction of hospital resources during influenza outbreaks]. / Unidad domiciliaria de atención integral: Reducción de recursos hospitalarios durante brotes de gripe.

OBJECTIVE: The Comprehensive Care Home Unit of the General Hospital of Villarrobledo is a unit formed by a geriatrician who sees people in nursing homes to improve their quality of care. The activity of the Unit has been analyzed, mainly with the objective of avoiding referral to the emergency room, avoiding hospital admissions, avoiding hospital readmissions and reducing the number of hospital admission days. METHODS: We retrospectively described the clinical activity of the Unit during the influenza outbreak of 2017 and 2018. We selected sociodemographical variables, functional assessment scales (Katz index, Barthel index and the Functional Ambulation Classification), and the Global Deterioration Scale. We registered mortality, type of treatment, oncological patients and patients with supplementary tests. The population was divided into four subgroups: hospital admission avoided, hospital re-admission avoided, referral to the emergency department avoided and reduction of admission days. The demographic characteristics were described, including the mode or mean of the variables. An economic report was made, and an analysis of cost per process according to the subgroups, means of Related Groups for the Diagnosis and degree of dependency measured by the Barthel index. RESULTS: We selected 112 patients, they had a mean age of 82.2 years, Katz G (34.8%), IB 28.8 (DE 34.9), FAC 0 (63.4%) and GDS 7 (22.3%). The most frequent disease seen was respiratory infection (63.2%), 71.4% received active treatment, 10.7% complementary tests were performed, 17.9% oncological and 17% mortality. Cost analysis: hospital readmission avoided (€ 4,128 per patient) and patients with total disability (BI 0-20, € 3,623 per patient) presented more economic saving. The economic savings were more than € 230,000. CONCLUSIONS: The contribution of the Unit during periods of influenza outbreak is cost saving because of reduced numbers of admissions, numbers of readmissions, days of admission and emergency room visits.

OBJETIVO: La Unidad Domiciliaria de Atención Integral (UDAI) del Hospital General de Villarrobledo está formada por un geriatra que atiende a las personas institucionalizadas para mejorar su calidad asistencial. Se analizó la actividad de la UDAI, principalmente en el objetivo de evitar ingresos y reingresos hospitalarios, evitar visitas a urgencias y facilitar el alta hospitalaria prematura. METODOS: Describimos de forma retrospectiva la actividad de la UDAI durante los brotes de gripe del 2017 y 2018. Aportamos variables sociodemográficas, escalas de valoración funcional (índice de Katz, índice de Barthel y la Escala de Valoración Funcional de la Marcha), y la Escala de Deterioro Global. Registramos mortalidad, tipo de tratamiento, pacientes oncológicos y pruebas complementarias. Se dividió la población en cuatro subgrupos: ingreso hospitalario evitado, reingreso hospitalario evitado, derivación a urgencias evitada y reducción días de ingreso. Se describieron las características demográficas, incluido la moda o media de las variables. Se realizó una memoria económica, y un análisis de coste por proceso según los subgrupos, medias de Grupos Relacionados por el Diagnóstico y grado de dependencia medido por el Índice de Barthel. RESULTADOS: Se seleccionaron 112 pacientes, presentaban una edad media de 82,2 años, Katz G (34,8%), IB 28,8 (DE 34,9), FAC 0 (63,4%) y GDS 7 (22,3%). La enfermedad más frecuente fue la infección respiratoria (63,4%), recibieron tratamiento activo un 71,4%, se realizaron pruebas complementarias en un 10,7%, oncológico 17,9% y exitus 17%. Análisis de costes: el reingreso hospitalario evitado (4.128 € por paciente) y los pacientes con discapacidad total (IB 0 ­ 20, 3.623 € por paciente) presentaron un mayor ahorro de costes. El ahorro económico fue de más de 230.000€. CONCLUSIONES: La contribución de la UDAI durante los periodos de brote de gripe supone un ahorro de costes basado en disminuciones de hospitalizaciones, disminución de reingresos, acortamiento de estancias hospitalarias y reducción de derivaciones a urgencias.

[Geriatric assessment tools in Spanish Geriatric Departments]. / Herramientas de valoración geriátrica en Servicios de Geriatría españoles.

INTRODUCTION: Comprehensive Geriatric Assessment (CGA) is the main measurement tool used by Geriatricians. A 2000 survey demonstrated great variability in the tools used for CGA among Spanish Geriatric Departments. A new survey to detect 13-year trends in the use of CGA tools in our country is presented. MATERIAL AND METHODS: Descriptive study using a structured questionnaire on the use of CGA tools in different levels of care sent to the Heads of 39 Spanish Geriatric Departments or Services (27 with postgraduate teaching in Geriatrics) during the first three months of 2013. RESULTS: The response rate was 97.4%. It was found that 78.4% (29 centers) used different tools depending on the level of care. Barthel and Lawton index were the most used functional assessment tools in all Departments and across all geriatric levels, although gait speed and Tinetti scale were frequently used in Day Hospital and Outpatient clinics. The Mini Mental State Exam and its Spanish version Mini Examen Cognoscitivo were the most used mental scales (97.4%), followed by tools for assessing depression-behavior (86.8%) and severity of cognitive impairment tools (84.2%). CGA tools were used in 43.2% of the emergency departments of the hospitals surveyed, being the most frequent. More than two-thirds (69.4%) of the Departments reported that their affiliated Primary Care centers used CGA tools, with the Barthel and Lawton again being indexes the most used. Most of the responding Departments considered that the main domains of CGA are functional, mental and social status. Nutrition, comorbidity, falls and pressure ulcers are other important domains. CONCLUSIONS: There is still a great variability in the CGA tools being used in Spanish Geriatric Departments, although there is a trend towards a greater use of Barthel index, greater adaptation of tools to each level of care, and increasing assessment of new domains like frailty, nutrition or comorbidity.

[Normal data of functional assessment tools of the elderly in Spain: the FRADEA study]. / Valores normativos de instrumentos de valoración funcional en ancianos españoles: estudio FRADEA.

OBJECTIVE: To determine the normal values of some of the functional assessment tools most used in Spain. DESIGN: Cross-sectional study of the first cut of a concurrent population based cohort. SETTING: Albacete city Health Area. PARTICIPANTS: A total of 993 subjects aged 70 years or over and participants in the FRADEA (Frailty and dependence in Albacete, Spain) cohort. MAIN MEASUREMENTS: An analysis was made of disability and function questionnaires, which included, Barthel, Lawton and Short Form of the Late-Life Function and Disability Instrument (SF-LLFDI), Holden's Functional Ambulation Category (FAC), and functional tests: walking speed (m/s), Timed Up and Go (TUG) (sec), one-leg balance time (sec), timed 5 Times Sit to Stand Test (5STS) (seg), Short Physical Performance Battery (SPPB), grip strength (kg), and elbow flexion strength (kg). The means, quartiles and percentiles are described, in the global cohort and in the male and female sub-groups aged between 70 and 79 years or aged 80 years or over. RESULTS: The quartiles of the different instruments were as follow: Barthel (80, 95, 100), Lawton (3, 6,8), SF-LLFDI (70, 111, 131), FAC (4, 5, 5), walking speed (0.51, 0.79, 1.00), TUG (13.8, 11.4, 9.8), one-leg balance time (3, 7, 15), 5STS (16.3, 13.0, 10.7), SPPB (7, 9, 11), grip strength (15, 20, 29), and elbow flexion strength (11, 20, 32). The younger ones, males and those living within the community showed a better performance in all the instruments. CONCLUSIONS: The normal values of a cohort of the elderly population based in Albacete using different functional assessment instruments are presented. These could be useful in clinical practice or research.

[Comorbidity in the elderly: utility and validity of assessment tools]. / Evaluación de la comorbilidad en la población anciana: utilidad y validez de los instrumentos de medida.

Comorbidity is common in the elderly and contributes to the complexity of this population subgroup. This problem is a risk factor for major adverse events such as functional decline, disability, dependency, poor quality-of-life, institutionalization, hospitalization and death, but is not the most important factor. Age and risk of functional decline rather than comorbidity (understood as a compilation of diseases) are the main characteristics defining the target population attended by geriatricians. Comorbidity indexes should not be interpreted independently in the elderly, but within a context of comprehensive geriatric assessment that includes age-related preclinical dysfunctions, frailty measures, and functional, mental and psychosocial issues. The clinical management of comorbidity in the elderly requires advanced knowledge of geriatrics because the treatment of one condition may worsen or lead to the development of others and because preclinical physiological dysfunctions modulate drug response. Recommending a specific comorbidity index is difficult and depends on multiple factors, due to their psychometric characteristics, applicability in the elderly and their construct. However, the Cumulative Illness Rating Scale, in the version adapted to the elderly, could be highly suitable. Other instruments, such as the Charlson index, the Index of CoExistent Disease and the Kaplan index are also valid and reproducible.
