Objective: Amyotrophic Lateral Sclerosis (ALS) is a heterogeneous neurodegenerative disorder with a median survival of 3 years. The aim of our study is to analyze the incidence, age-related phenotype and clinical onset, geographical distribution, survival and diagnostic delay of ALS in Navarre. Methods: This is a population-based observational retrospective study, including all residents of Navarre (a northern Spanish region) from 2007 to 2018, who were followed until 30th September 2020. Results: We observed a global incidence 2.47/100,000 person-years, with an upward trend throughout the study, with the highest being in the age group of 70¿74 years old. Point prevalence in December 2018 was 6.64/100,000 inhabitants (95%CI: 4.52¿8.45). Upper limbs weakness onset was the most frequent in young people (<60 years), and bulbar, lower limbs weakness, generalized and respiratory associated with older age. Bulbar phenotype is the most frequent in women and in 80+ group. The median survival from clinical onset was 27.7 months (95%CI: 24.0¿31.4), higher in spinal phenotype and younger onset age, and the diagnosis delay was 10.0 months (95%CI: 8.9¿11.2) from clinical onset. Conclusions: We have observed a trend of increasing incidence in older people where the bulbar phenotype and female predominance. © 2021 World Federation of Neurology on behalf of the Research Group on Motor Neuron Diseases.

(2014) Galbete Jiménez, Arkaitz; Moler Cuiral, José Antonio; Plo, Fernando; Estadística e Investigación Operativa; Estatistika eta Ikerketa Operatiboa
Un ensayo clínico es un experimento estadístico que consiste en comparar el comportamiento de dos tratamientos con objeto de establecer la superioridad de uno respecto al otro. En esta tesis se ha presentado un nuevo diseño de ensayo clínico adaptado a la respuesta, llamado diseño urna de Klein, que intenta combinar buenas propiedades éticas e inferenciales. A su vez, se han estudiado sus propiedades exactas y asintóticas y se compara el nuevo diseño con otros diseños destacados en la literatura estadística. Se realiza un estudio detallado de inferencia basado en la aleatorización desde un punto de vista exacto y asintótico. Finalmente, se analiza la inclusión de variables en el diseño.

Background. Hospitalization exacerbates sarcopenia and physical dysfunction in older adults. Whether tailored inpatient exercise prevents acute sarcopenia is unknown. This study aimed to examine the effect of a multicomponent exercise programme on muscle and physical function in hospitalized older adults. We hypothesized that participation in a brief tailored exercise regimen (i.e., 3–5 days) would attenuate muscle function and structure changes compared with usual hospital care alone. Methods. This randomized clinical trial with blinded outcome assessment was conducted from May 2018 to April 2021 at Hospital Universitario de Navarra, Spain. Participants were 130 patients aged 75 years and older admitted to an acute care geriatric unit. Patients were randomized to a tailored 3- to 5-day exercise programme (n = 64) or usual hospital care (control, n = 66) consisting of physical therapy if needed. The coprimary endpoints were between-group differences in changes in short physical performance battery (SPPB) score and usual gait velocity from hospital admission to discharge. Secondary endpoints included changes in rectus femoris echo intensity, cross-sectional area, thickness and subcutaneous and intramuscular fat by ultrasound. Results. Among 130 randomized patients (mean [SD] age, 87.7 [4.6] years; 57 [44%] women), the exercise group increased their mean SPPB score by 0.98 points (95% CI, 0.28–1.69 points) and gait velocity by 0.09 m/s (95% CI, 0.03–0.15 m/s) more than controls (both p < 0.01). No between-group differences were observed in any ultrasound muscle outcomes. There were no study-related adverse events. Conclusions. Three to 5 days of tailored multicomponent exercise provided functional benefits but did not alter muscle or fat architecture compared with usual hospital care alone among vulnerable older patients. Brief exercise may help prevent acute sarcopenia during hospitalization.

(Elsevier, 2024-09-27) López Sáez de Asteasu, Mikel; Martínez Velilla, Nicolás; Ramírez Vélez, Robinson; Zambom Ferraresi, Fabrício; Galbete Jiménez, Arkaitz; Lusa Cadore, Eduardo; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Estadística, Informática y Matemáticas; Estatistika, Informatika eta Matematika; Gobierno de Navarra / Nafarroako Gobernua, 2186/2014
Background. Sex-based differences in the clinical presentation and outcomes are well-established in patients hospitalized for geriatric syndromes. We aimed to investigate sex differences in response to in-hospital exercise on function, strength, cognition, and quality of life in acute care admissions. Methods. 570 patients (mean age 87 years, 298 females [52.3%]) admitted to acute care for elderly units were randomized to multicomponent exercise emphasizing progressive resistance training or usual care. Functional assessments included Short Physical Performance Battery (SPPB), grip strength, Mini-Mental State Examination (MMSE), and health-related quality of life (EQ-VAS). Results. Exercising females showed more significant SPPB improvements than males (between-group difference 1.48 points, p = 0.027), exceeding the minimal clinically significant difference. While female participants significantly increased handgrip strength and male patients improved cognition after in-hospital exercise compared to the control group (all p < 0.001), no sex differences occurred. Conclusions. Females demonstrate more excellent physical function improvements compared to male older patients. Findings highlight the importance of tailored exercise incorporating patient factors like biological sex in geriatric medicine. Trial registration. NCT04600453

Objectives: this study aimed to assess the prevalence and impact of loneliness (De Jong Gierveld scale) and isolation (Lubben scale) on the effects of a hospital-based exercise programme. Design: secondary analysis of a randomised clinical trial. Setting: Acute Geriatric Unit of a tertiary hospital in Spain. Participants: 103 hospitalised older adults. Intervention: individualised multicomponent exercise program (20-minute sessions twice a day for 3 consecutive days). Results: among the 103 randomised patients included in the analysis (both arms included), 58.3% were male, and their mean age was 87.3 (4.5) years. According to the Lubben scale, 15.8% of patients were at risk of isolation, while 62.7% were in a situation of severe or moderate loneliness according to the De Jong Gierveld scale. In the non-isolated group, training showed a substantial positive impact on Geriatric Depression Scale (B = -1.25, 95% CI = -0.24 to -0.27). In the isolated group, all outcomes improved, but only the Quality of Life showed significant changes (B = 35, 95% CI = 4.96-35.8). The SPPB test (B = 1.62, 95% CI = 0.19-3.04) and Quality of Life, (B = 17.1, 95% CI = 1.84-32.3) showed a significant improvement in the non-loneliness exercise group while no differences were found in the loneliness group. Conclusion: despite the high prevalence of loneliness and social isolation, individualised exercise programs provide significant benefits to hospitalised patients, especially in quality of life.

Aims: to identify all cardiovascular disease risk prediction models developed in patients with type 2 diabetes or in the general population with diabetes as a covariate updating previous studies, describing model performance and analysing both their risk of bias and their applicability. Methods: a systematic search for predictive models of cardiovascular risk was performed in PubMed. The CHARMS and PROBAST guidelines for data extraction and for the assessment of risk of bias and applicability were followed. Google Scholar citations of the selected articles were reviewed to identify studies that conducted external validations. Results: the titles of 10,556 references were extracted to ultimately identify 19 studies with models developed in a population with diabetes and 46 studies in the general population. Within models developed in a population with diabetes, only six were classified as having a low risk of bias, 17 had a favourable assessment of applicability, 11 reported complete model information, and also 11 were externally validated. Conclusions: there exists an overabundance of cardiovascular risk prediction models applicable to patients with diabetes, but many have a high risk of bias due to methodological shortcomings and independent validations are scarce. We recommend following the existing guidelines to facilitate their applicability.

BACKGROUND: Cancer mostly affects older adults, causing a wide variety of diagnostic and therapeutic dilemmas. One of the most important moments in cancer patients is the hospitalization period, in which older patients usually remain bedridden for many hours and this may lead to the appearance of sarcopenia and disability. METHODS: We present the research protocol for a randomized controlled trial that will analyze whether an intervention applied to older patients (≥ 65 years) who are hospitalized for acute medical conditions in an Oncology Department improves function. A total of 240 hospitalized older patients will be recruited in the Hospital Universitario de Navarra, Pamplona, Spain, and they will be randomized. The intervention consists of a multicomponent exercise training program that will take place for 4 consecutive days (2 sessions/day). The control group will receive usual hospital care, which will include physical rehabilitation when needed. The primary end point will be the change in functional capacity from baseline to hospital discharge, assessed with the Short Physical Performance Battery (SPPB). Secondary end points will be changes in cognitive and mood status, quality of life, fatigue, strength (dynamic and handgrip), pain, nutrition, length of stay, falls, readmission rate and mortality at 3 months after discharge. RESULTS: Basal data of the patients included in the RCT are described. The foreseen recruitment will not be achieved due to the context of the Covid pandemic and the significantly different responses observed during the clinical trial in oncogeriatric patients compared to our previous experience in older adults hospitalized for medical reasons. DISCUSSION: If our hypothesis is correct and shows that a multicomponent, individualized and progressive exercise program is an effective therapy for improving the capacity of acutely hospitalized older patients compared to usual care, a change in the current system of hospitalization may be justified in oncogeriatric patients.

Background: Different multimorbidity patterns present with different prognoses, but it is unknown to what extent they may influence the effectiveness of an individualized multicomponent exercise program offered to hospitalized older adults. Methods: This study is a secondary analysis of a randomized controlled trial conducted in the Department of Geriatric Medicine of a tertiary hospital. In addition to the standard care, an exercise-training multicomponent program was delivered to the intervention group during the acute hospitalization period. Multimorbidity patterns were determined through fuzzy c-means cluster analysis, over 38 chronic diseases. Functional, cognitive and affective outcomes were considered. Results: Three hundred and six patients were included in the analyses (154 control; 152 intervention), with a mean age of 87.2 years, and 58.5% being female. Four patterns of multimorbidity were identified: heart valves and prostate diseases (26.8%); metabolic diseases and colitis (20.6%); psychiatric, cardiovascular and autoimmune diseases (16%); and an unspecific pattern (36.6%). The Short Physical Performance Battery (SPPB) test improved across all patterns, but the intervention was most effective for patients in the metabolic/colitis pattern (2.48-point difference between intervention/control groups, 95% CI 1.60-3.35). Regarding the Barthel Index and the Mini Mental State Examination (MMSE), the differences were significant for all multimorbidity patterns, except for the psychiatric/cardio/autoimmune pattern. Differences concerning quality of life were especially high for the psychiatric/cardio/autoimmune pattern (16.9-point difference between intervention/control groups, 95% CI 4.04, 29.7). Conclusions: Patients in all the analyzed multimorbidity patterns improved with this tailored program, but the improvement was highest for those in the metabolic pattern. Understanding how different chronic disease combinations are associated with specific functional and cognitive responses to a multicomponent exercise intervention may allow further tailoring such interventions to older patients’ clinical profile.
