    (Wiley Open Access, 2022) Casas Herrero, Álvaro; Sáez de Asteasu, Mikel L.; Antón Rodrigo, Iván; Sánchez Sánchez, Juan Luis; Montero Odasso, Manuel; Marín Epelde, Itxaso; Ramón Espinoza, Fernanda; Zambom Ferraresi, Fabrício; Petidier Torregrosa, Roberto; Elexpuru Estomba, Jaione; Álvarez Bustos, Alejandro; Galbete Jiménez, Arkaitz; Martínez Velilla, Nicolás; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua
    Background: physical exercise is an effective strategy for preserving functional capacity and improving the symptoms of frailty in older adults. In addition to functional gains, exercise is considered to be a cornerstone for enhancing cognitive function in frail older adults with cognitive impairment and dementia. We assessed the effects of the Vivifrail exercise intervention for functional capacity, cognition, and well-being status in community-dwelling older adults. Methods: in a multicentre randomized controlled trial conducted in three tertiary hospitals in Spain, a total of 188 older patients with mild cognitive impairment or mild dementia (aged >75 years) were randomly assigned to an exercise intervention (n = 88) or a usual-care, control (n = 100) group. The intervention was based on the Vivifrail tailored multicomponent exercise programme, which included resistance, balance, flexibility (3 days/week), and gait-retraining exercises (5 days/week) and was performed for three consecutive months (http://vivifrail.com). The usual-care group received habitual outpatient care. The main endpoint was change in functional capacity from baseline to 1 and 3 months, assessed with the Short Physical Performance Battery (SPPB). Secondary endpoints were changes in cognitive function and handgrip strength after 1 and 3 months, and well-being status, falls, hospital admission rate, visits to the emergency department, and mortality after 3 months. Results: the Vivifrail exercise programme provided significant benefits in functional capacity over usual-care. The mean adherence to the exercise sessions was 79% in the first month and 68% in the following 2 months. The intervention group showed a mean increase (over the control group) of 0.86 points on the SPPB scale (95% confidence interval [CI] 0.32, 1.41 points; P < 0.01) after 1 month of intervention and 1.40 points (95% CI 0.82, 1.98 points; P < 0.001) after 3 months. Participants in the usual-care group showed no significant benefit in functional capacity (mean change of −0.17 points [95% CI −0.54, 0.19 points] after 1 month and −0.33 points [95% CI −0.70, 0.04 points] after 3 months), whereas the exercise intervention reversed this trend (0.69 points [95% CI 0.29, 1.09 points] after 1 month and 1.07 points [95% CI 0.63, 1.51 points] after 3 months). Exercise group also obtained significant benefits in cognitive function, muscle function, and depression after 3 months over control group (P < 0.05). No between-group differences were obtained in other secondary endpoints (P > 0.05). Conclusions: the Vivifrail exercise training programme is an effective and safe therapy for improving functional capacity in community-dwelling frail/prefrail older patients with mild cognitive impairment or mild dementia and also seems to have beneficial effect on cognition, muscle function, and mood status.

    Periostin plasma levels and changes on physical and cognitive capacities in community-dwelling older adults
    (Oxford University Press, 2023) Sánchez Sánchez, Juan Luis; Ader, Isabelle; Jeanson, Yannick; Planat-Benard, Valérie; Vellas, Bruno; Casteilla, Louis; Souto Barreto, Philipe de; Ciencias de la Salud; Osasun Zientziak
    Periostin, involved in extracellular matrix development and support, has been shown to be elevated in senescent tissues and fibrotic states, transversal signatures of aging. We aimed to explore associations between plasma periostin and physical and cognitive capacity evolution among older adults. Our hypothesis was that higher levels of plasma periostin will be associated with worse physical and mental capacities along time. Analyses included 1 096 participants (mean age = 75.3 years ± 4.4; 63.9% women) from the Multidomain Alzheimer Preventive Trial. Periostin levels (pg/mL) were measured in plasma collected at year 1. Periostin was used in continuous variable, and as a dichotomous variable highest quartile (POSTN+) versus lowest 3 quartiles (POSTN−) were used. Outcomes were measured annually over 4 years and included: gait speed (GS), short physical performance battery (SPPB) score, 5-times sit-to-stand test (5-STS), and handgrip strength (HS) as physical and cognitive composite z-score (CCS) and the Mini-Mental State Examination (MMSE) as cognitive endpoints. Plasma periostin as a continuous variable was associated with the worsening of physical and cognitive capacities over 4 years of follow-up, specifically the SPPB score, the 5-STS, and CCS in full-adjusted models. POSTN+ was associated with worse evolution in the physical (GS: [β = −0.057, 95% confidence interval (CI) = −0.101, −0.013], SPPB score [β = −0.736, 95% CI = −1.091, −0.381], 5-STS [β = 1.681, 95% CI = 0.801, 2.561]) as well as cognitive (CCS [β = −0.215, 95% CI = −0.335, −0.094]) domains compared to POSTN− group. No association was found with HS or the MMSE score. Our study showed for the first time that increased plasma periostin levels were associated with declines in both physical and cognitive capacities in older adults over a 4-year follow-up. Further research is needed to evaluate whether periostin might be used as a predictive biomarker of functional decline at an older age.

    Effects of a 12-week Vivifrail exercise program on intrinsic capacity among frail cognitively impaired community-dwelling older adults: secondary analysis of a multicentre randomised clinical trial
    (Oxford University Press, 2022) Sánchez Sánchez, Juan Luis; Souto Barreto, Philipe de; Antón Rodrigo, Iván; Ramón Espinoza, Fernanda; Marín Epelde, Itxaso; Sánchez Latorre, Marina; Moral Cuesta, Débora; Casas Herrero, Álvaro; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua
    Introduction: The World Health Organisation recently defined the construct of intrinsic capacity (IC), a function-based marker of older adult’s health encompassing all mental and physical capacities of the individual. Multicomponent physical exercise (MCE) is a potential intervention capable to maintain/increase IC at older age; however, evidence is scarce on the effects of MCE on IC in cognitively impaired pre-frail/frail older adults. Methods: Secondary analyses of a randomised clinical trial. One hundred and eighty-eight older outpatients (age = 84.06 ± 4.77, 70.2% women) presenting with pre-frailty/frailty (according to Fried Criteria) and mild cognitive impairment (MCI)/mild dementia were recruited in the Geriatric clinics of three tertiary hospitals in Spain. Subjects were randomised to participate in the 12-week home-based individualised Vivifrail MCE or usual care. An IC index was created based on the z-score of the locomotion (Short Physical Performance Battery), cognitive (Montreal Cognitive Assessment), psychology (15-item Geriatric Depression Scale Yesavage) and vitality (handgrip strength) domains. Results: After the 3-month intervention, linear mixed models showed significant between-group differences in the evolution of the IC composite score (β=0.48; 95% confidence interval [CI] = 0.24, 0.74; P < 0.001), IC Locomotion (β = 0.42; 95% CI = 0.10, 0.74; P < 0.001), IC Cognition (β = 0.45; 95% CI = 0.03, 0.87; P < 0.05) and IC Vitality domains (β = 0.50; 95% CI = 0.25, 0.74 at 3-month) favouring the MCE group. Conclusions: The 12-week Vivifrail multicomponent exercise program is an effective strategy to enhance IC, especially in terms of locomotion, cognition and vitality IC domains in community-dwelling older adults with pre-frailty/frailty and MCI/mild dementia, compared to usual care.

    Physical behaviors, sarcopenia and adverse events in the Toledo Study of Healthy Ageing
    (2020) Sánchez Sánchez, Juan Luis; Izquierdo Redín, Mikel; Rodríguez Mañas, Leocadio; Ciencias de la Salud; Osasun Zientziak
    El envejecimiento de la población es un fenómeno global que puede tener unas implicaciones relevantes tanto a nivel de la salud individual como en los sistemas sanitarios. Esto se debe a que los aumentos en la esperanza de vida observados en los últimos siglos no se han visto acompañados concurrentemente de aumentos de los años vividos sin enfermedad. El desarrollo de enfermedades crónicas y su aparición en forma de comorbilidad unido a los efectos del envejecimiento primario ha derivado en la progresiva pérdida de función y el desarrollo de discapacidad. El envejecimiento saludable se define como el mantenimiento de la capacidad funcional que garantiza el bienestar en el adulto mayor. En contraposición, la acumulación de patologías y la presencia de estilos de vida no saludables pueden condicionar un envejecimiento acelerado y la emergencia prematura de la discapacidad. La pérdida de masa y función muscular que acompaña al envejecimiento (sarcopenia), constituye una de las piedras angulares en el desarrollo de la discapacidad en el anciano. El ejercicio físico ha sido propuesto como la herramienta de elección para mantener y aumentar la función física en ancianos y, por ende, prevenir el deterioro funcional asociado con la sarcopenia. Sin embargo, muy pocos sujetos ancianos participan en programas estructurados de ejercicio y los parámetros óptimos de esos programas se desconocen. En ese contexto, los comportamientos físicos espontáneos (comportamiento sedentario y actividad física), podrían ser determinantes relevantes de la capacidad funcional en el anciano. La incorporación de medidas objetivas en la epidemiología de la actividad física y el reciente desarrollo de nuevos métodos estadísticos ha permitido atender preguntas de investigación como las asociaciones del sedentarismo y distintos niveles de intensidad de actividad física con parámetros de salud e incorporar la naturaleza dinámica de los comportamientos físicos como factor determinante de salud. La presente tesis doctoral pretende profundizar en las asociaciones entre los niveles de actividad física y sedentarismo e indicadores de envejecimiento saludable (sarcopenia y eventos adversos), superando algunas limitaciones identificadas en la evidencia previa. En la misma se han incluido dos trabajos realizados con datos del Estudio de Toledo del Envejecimiento Saludable, un estudio poblacional en curso.

    Plasma inflammatory biomarkers and anorexia of ageing among community-dwelling older adults: an exploratory analysis of the MAPT Study
    (Springer, 2023) Sánchez Sánchez, Juan Luis; Guyonnet, Sophie; Lucas, Alexandre; Parini, Angelo; Rolland, Y.; Souto Barreto, Philipe de; Ciencias de la Salud; Osasun Zientziak
    Anorexia of aging and biological aging might share physiological underpinnings. The aim of this secondary analysis was to investigate the associations between circulating inflammation-related markers and anorexia of aging in community-dwelling older adults. C-reactive protein (CRP), tumor necrosis factor receptor-1 (TNFR-1), interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1) and growth/differentiation factor-15 (GDF-15) were measured in plasma. Anorexia of aging was defined by the response “severe/moderate decrease in food intake” to the first item of the Mini-Nutritional Assessment. We included 463 subjects (median age=74y, IQR=71–78; 63.1% women). 33 subjects (7.1%) presented with anorexia at baseline, whereas 25 out of 363 (6.9%) developed it along 1-year follow-up. We found that TNFR1 (OR=1.74, 95%CI=1.27–2.39) and GDF-15 (OR=1.38, 95%CI=1.01–1.89) were associated with a significant increase in the odds of presenting with anorexia of aging cross-sectionally. No further significant associations were found. Biological aging mechanisms might be involved in the pathogenesis of anorexia of aging.

    Effect of a multicomponent exercise programme (VIVIFRAIL) on functional capacity in frail community elders with cognitive decline: study protocol for a randomized multicentre control trial
    (BioMed Central, 2019) Casas Herrero, Álvaro; Antón Rodrigo, Iván; Zambom Ferraresi, Fabrício; López Sáez de Asteasu, Mikel; Martínez Velilla, Nicolás; Elexpuru Estomba, Jaione; Marín Epelde, Itxaso; Ramón Espinoza, Fernanda; Petidier Torregrosa, Roberto; Sánchez Sánchez, Juan Luis; Ibáñez Beroiz, Berta; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua
    Background: The benefit of physical exercise in ageing and particularly in frailty has been the aim of recent research. Moreover, physical activity in the elderly is associated with a decreased risk of mortality, of common chronic illnesses (i.e. cardiovascular disease or osteoarthritis) and of institutionalization as well as with a delay in functional decline. Additionally, very recent research has shown that, despite its limitations, physical exercise is associated with a reduced risk of dementia, Alzheimer disease or mild cognitive decline. Nevertheless, the effect of physical exercise as a systematic, structured and repetitive type of physical activity, in the reduction of risk of cognitive decline in the elderly, is not very clear. The purpose of this study aims to examine whether an innovative multicomponent exercise programme called VIVIFRAIL has benefits for functional and cognitive status among pre-frail/frail patients with mild cognitive impairment or dementia. Methods/design: This study is a multicentre randomized clinical trial to be conducted in the outpatient geriatrics clinics of three tertiary hospitals in Spain. Altogether, 240 patients aged 75 years or older being capable of and willing to provide informed consent, with a Barthel Index ≥ 60 and mild cognitive impairment or mild dementia, pre-frail or frail and having someone to help to supervise them when conducting the exercises will be randomly assigned to the intervention or control group. Participants randomly assigned to the usual care group will receive normal outpatient care, including physical rehabilitation when needed. The VIVIFRAIL multicomponent exercise intervention programme consists of resistance training, gait re-training and balance training, which appear to be the best strategy for improving gait, balance and strength, as well as reducing the rate of falls in older individuals and consequently maintaining their functional capacity during ageing. The primary endpoint is the change in functional capacity, assessed with the Short Physical Performance Battery (1 point as clinically significant). Secondary endpoints are changes in cognitive and mood status, quality of life (EQ-5D), 6-m gait velocity and changes in gait parameters (i.e. gait velocity and gait variability) while performing a dual-task test (verbal and counting), handgrip, maximal strength and power of the lower limbs as well as Barthel Index of independence (5 points as clinically significant) at baseline and at the 1-month and 3-month follow-up. Discussion: Frailty and cognitive impairment are two very common geriatric syndromes in elderly patients and are frequently related and overlapped. Functional decline and disability are major adverse outcomes of these conditions. Exercise is a potential intervention for both syndromes. If our hypothesis is correct, the relevance of this project is that the results can contribute to understanding that an individualized multicomponent exercise programme (VIVIFRAIL) for frail elderly patients with cognitive impairment is more effective in reducing functional and cognitive impairment than conventional care. Moreover, our study may be able to show that an innovative individualized multicomponent exercise prescription for these high-risk populations is plausible, having at least similar therapeutic effects to other pharmacological and medical prescriptions.

    Physical activity trajectories, mortality, hospitalization, and disability in the Toledo Study of Healthy Aging
    (Wiley, 2020) Sánchez Sánchez, Juan Luis; Izquierdo Redín, Mikel; Carnicero Carreño, Jose Antonio; García García, Francisco José; Rodríguez Mañas, Leocadio; Ciencias de la Salud; Osasun Zientziak
    Background: Physical activity (PA) is a recognized contributor to healthy aging. However, the majority of studies exploring its associations with adverse outcomes in cohorts of older adults use single-time PA estimates, which do not consider its dynamic nature. The aim of the present study is to explore the presence of different PA trajectories in the Toledo Study of Healthy Aging and their association with adverse outcomes. Our hypothesis is that prospectively maintaining or increasing PA is associated with a reduced risk of adverse outcomes. Methods: We used data from 1679 participants enrolled in the Toledo Study of Healthy Aging. Trajectories based on the Physical Activity Scale for the Elderly were identified using group-based trajectory modelling. Cox and logistic regression were used to investigate associations between PA trajectories and mortality and hospitalization, and incident and worsening disability, respectively. Mortality was ascertained by linkage to the Spanish National Death Index; disability was evaluated through the Katz Index; and hospitalization was defined as the first admission to Toledo Hospital. Models were adjusted by age, sex, smoking, Charlson Index, education, cognitive impairment, polypharmacy, and Katz Index at Wave 2. Results: We found four PA-decreasing and one PA-increasing trajectories: high PA-consistent (n = 566), moderate PA-mildly decreasing (n = 392), low PA-increasing (n = 237), moderate PA-consistent (n = 191), and low PA-decreasing (n = 293). Belonging to the high PA-consistent trajectory group was associated with reduced risks of mortality as compared with the low PA-decreasing group [hazard ratio (HR) 1.68; 95% confidence interval (CI) = 1.21–2.31] and hospitalization compared with the low PA-increasing and low PA-decreasing trajectory groups (HR 1.24; 95% CI = 1.004–1.54 and HR 1.25; 95% CI = 1.01–1.55, respectively) and with lower rates of incident [odds ratio (OR) 3.14; 95% CI = 1.59–6.19] and worsening disability (OR 2.16; 95% CI = 1.35–3.45) in relation to the low PA-decreasing trajectory group and at follow-up. Increasing PA during late life (low PA-increasing group) was associated with lower incident disability rates (OR 0.38; 95% CI = 0.19–0.82) compared with decreasing PA (low PA-decreasing group), despite similar baseline PA. Conclusions: Our results suggest that sustaining higher PA levels during aging might lead to healthy aging, characterized by a reduction in adverse outcomes. Our study supports the need for enhancing PA participation among older populations, with the goal of reducing personal and economic burden in a worldwide aging population.

    Comment on 'Effects of Vivifrail multicomponent intervention on functional capacity' by Casas-Herrero et al.-The authors reply.
    (Wiley, 2024) Sánchez Sánchez, Juan Luis; Izquierdo Redín, Mikel; López Sáez de Asteasu, Mikel; Antón Rodrigo, Iván; Galbete Jiménez, Arkaitz; Álvarez Bustos, Alejandro; Casas Herrero, Álvaro; Ciencias de la Salud; Osasun Zientziak; Estadística, Informática y Matemáticas; Estatistika, Informatika eta Matematika; Institute of Smart Cities - ISC
    In this response letter, we would like to clarify some aspects related to the methodology and inferences derived from our work entitled 'Effects of Vivifrail multicomponent intervention on functional capacity', which was aimed at investigating the effects of a home-based multicomponent individualized exercise programme (Vivifrail) on the functional capacity of frail older adults with mild cognitive impairment/dementia. Yan et al.2 raised concerns related to the amount of data missingness and methods used to handle it in our study. Although we addressed this issue as a limitation of the Discussion section of the original report, we now take the opportunity to further discuss its implications.

    Association of physical behaviours with sarcopenia in older adults: a systematic review and meta-analysis of observational studies
    (Elsevier, 2024) Sánchez Sánchez, Juan Luis; He, Lingxiao; Morales, Javier S.; Souto Barreto, Philipe de; Jiménez Pavón, David; Carbonell-Baeza, Ana; Casas Herrero, Álvaro; Gallardo-Gómez, Daniel; Lucía, Alejandro; Pozo Cruz, Borja del; Valenzuela, Pedro L.; Ciencias de la Salud; Osasun Zientziak
    Contexto: Los comportamientos físicos (esto es, la actividad física y el comportamiento sedentario) parecen influenciar el desarrollo de la sarcopenia, aunque la evidencia al respecto presenta limitaciones. Este estudio tuvo como objetivo explorar la asociación entre la actividad física total, distintos niveles de intensidad de la actividad física y el comportamiento sedentario, y la sarcopenia y sus componentes (masa muscular, fuerza muscular y función física) en adultos mayores. Métodos: Se llevó a cabo una revisión sistemática y meta-análisis. Se realizó una búsqueda en las bases bibliográficas MEDLINE (vía Pubmed), Scopus y Web of Science hasta el 26 de julio de 2022 para identificar estudios revisados por pares, observacionales (o que utilizasen datos basales de estudios experimentales), que incluyeran adultos mayores (mayores de 60 años, o con medias mayores a 65 años) y publicados en inglés, que reportasen asociaciones entre los niveles de actividad física y/o comportamiento sedentario y la sarcopenia (o sus determinantes: masa muscular, fuerza muscular y función física). Se extrajeron los estimadores individuales y fueron meta-analizados por medio de modelos Bayesianos. Los sesgos de publicación fueron evaluados a través de la prueba de Egger. El estudio fue registrado en PROSPERO previo a su ejecución. Hallazgos: De los 15 766 registros encontrados, 124 (n=230174 adultos mayores, 52.7% mujeres) fueron incluidos en la revisión sistemática. De éstos, 86 pudieron ser incluidos en los meta-análisis. Niveles mayores de actividad física total se asociaron inversamente con la sarcopenia tanto a nivel transversal (21 estudios, n=59 572, razón de momios 0.49, 95% intervalo de credibilidad 0.37-0.62) como longitudinal (cuatro estudios, n=7545, razón de momios 0.51, 0.27-0.94). Además, la actividad física de moderada a vigorosa apuntó a poseer un rol protector frente al riesgo de presentar sarcopenia a nivel transversal (cinco estudios, n=6787, 0.85. 0.71-0.99), mientras que no observamos ninguna asociación para el resto de los comportamientos físicos analizados (número de pasos, actividad física ligera, o comportamiento sedentario). Interpretación: La actividad física total y de moderada a vigorosa se asocian inversamente con la sarcopenia. Estos resultados contribuyen a reforzar la importancia de la actividad física de mayor intensidad, frente a la actividad física ligera o las reducciones en el comportamiento sedentario, en la prevención de la sarcopenia, lo que podría guiar el diseño de intervenciones orientadas a minimizar este síndrome.

    Effect of a multicomponent exercise program and cognitive stimulation (VIVIFRAIL-COGN) on falls in frail community older persons with high risk of falls: study protocol for a randomized multicenter control trial
    (BMC, 2022) Sánchez Sánchez, Juan Luis; Udina, Cristina; Medina Rincón, Almudena; Esbrí Victor, Mariano; Bartolomé Martín, Irene; Moral Cuesta, Débora; Marín Epelde, Itxaso; Ramón Espinoza, Fernanda; Sánchez Latorre, Marina; Idoate, Fernando; Goñi-Sarriés, Adriana; Martínez Martínez, Blanca; Escudero Bonet, Raquel; Librero, Julián; Casas Herrero, Álvaro; Ciencias de la Salud; Osasun Zientziak
    Background: Falls represent important drivers of intrinsic capacity losses, functional limitations and reduced quality of life in the growing older adult’s population, especially among those presenting with frailty. Despite exercise- and cognitive training-based interventions have shown efectiveness for reducing fall rates, evidence around their puta‑ tive cumulative efects on falls and fall-related complications (such as fractures, reduced quality of life and functional limitations) in frail individuals remains scarce. The main aim of this study is to explore the efectiveness program combining an individualized exercise program and an executive function-based cognitive training (VIVIFRAIL-COGN) compared to usual care in the prevention of falls and fall-related outcomes over a 1-year follow-up. Methods: This study is designed as a four-center randomized clinical trial with a 12-week intervention period and an additional 1-year follow-up. Three hundred twenty frail or pre-frail (≥1 criteria of the Frailty Phenotype) older adults (≥75 years) with high risk of falling (defned by fall history and gait performance) will be recruited in the Falls Units of the participating centers. They will be randomized in a 1:1 ratio to the intervention group (IG) or the control group (CG). The IG will participate in a home-based intervention combining the individualized Vivifrail multicomponent (aerobic, resistance, gait and balance and fexibility) exercise program and a personalized executive function-based cognitive training (VIVIFRAIL-COGN). The CG group will receive usual care delivered in the Falls Units, including the Otago Exercise Program. Primary outcome will be the incidence of falls (event rate/year) and will be ascertained by self-report during three visits (at baseline, and 6 and 12 weeks) and telephone-based contacts at 6, 9 and 12 months after randomization. Secondarily, efects on measures of physical and cognitive function, quality of life, nutritional, muscle quality and psychological status will be evaluated. Discussion: This trial will provide new evidence about the efectiveness of an individualized multidomain interven‑ tion by studying the efect of additive efects of cognitive training and physical exercise to prevent falls in older frail persons with high risk of falling. Compared to usual care, the combined intervention is expected to show additive efects in the reduction of the incidence of falls and associated adverse outcomes.
