Introducción: los pacientes con Enfermedades Autoinmunes Sistémicas (EAS) tienen alto riesgo de desarrollar Enfermedad Tromboembólica Venosa (ETV). El comportamiento clínico una vez empiezan con el tratamiento anticoagulante acaba de ser descrito por el grupo RIETE durante este año. Material y métodos: creamos una base de datos en el Hospital Reina Sofía para comparar las tasas de recurrencias, sangrado mayor y muerte durante el tratamiento anticoagulante de acuerdo a la presencia o ausencia de EAS. Resultados: no se detectan diferencias significativas en las características basales de los pacientes salvo en la presencia de ETV idiopática y de anticuerpos antifosfolípidos. Los enfermos con EAS presentan mayores tasas de recurrencia estando bajo tratamiento anticoagulante y similares tasas de hemorragia y mortalidad. Conclusiones: en un escenario local y más homogéneo de partida que el observado en el RIETE, los enfermos con EAS presentan mayor tendencia a recurrir estando en tratamiento anticoagulante que los enfermos sin esta condición.

Background & aims: time-restricted eating (TRE) shows promise for weight loss and improving menopauserelated body composition and cardiometabolic health, but its effects on skeletal muscle tissue (SMT) in postmenopausal women are unknown. This study investigates the effects of three weight loss interventions over 12 weeks on SMT quantity, quality, function, and cardiometabolic health in postmenopausal women with overweight/obesity, with effects persistence evaluated at a 12-month follow-up. Methods and results: in this randomized controlled trial, 78 postmenopausal women (50–65 years; BMI 25–40 kg/m2; sedentary lifestyle; eating window ≥12 h/day; no severe metabolic impairments) will be recruited. Participants will be randomly assigned to one of three groups for 12 weeks: TRE, TRE + resistance training, or CR + resistance training. The TRE groups will reduce their eating window to 8 h and receive nutritional advice to adhere to a Mediterranean diet. The CR group will follow a personalized hypocaloric diet (− 500 kcal/day). Resistance training groups will perform supervised resistance training 3 times/week. Primary Outcome: Change in SMT quantity measured by MRI at baseline and after 12 weeks. Secondary Outcomes: intermuscular adipose tissue (IMAT), strength, power, body weight and composition, and cardiometabolic risk factors. Conclusion: this study will illustrate the effects of TRE and TRE combined with resistance exercise compared with the currently recommended obesity-lifestyle treatment on SMT quantity, quality, function, and cardiometabolic markers. The results will offer insights into dietary strategies to combat obesity and metabolic diseases without increasing sarcopenia risk in postmenopausal women, a sparsely studied and particularly affected population.

Background: Hospitalisation-associated disability due to reduced physical activity levels and prolonged bedrest episodes are highly prevalent in older adults. Objective: To assess the effect of gamified interventions on functional capacity in hospitalised older adults. Methods: A three-armed non-randomised controlled trial with two experimental intervention groups and a control group was conducted in a tertiary public hospital in Navarre, Spain. Participants were allocated to a simple gamification group (SGG) (n = 21), a technology-based gamification group (TGG) (n = 23) or a control group (CG) (n = 26). The end points were changes in functional capacity, muscle strength, cognition, mood status and quality of life. Results: Seventy patients (mean age 86.01 ± 4.27 years old) were included in the study; 29 (41.4%) were women. At discharge, compared to CG, a mean increase of 1.47 points (95%CI, 0.15–2.80 points) and 2.69 points (95%CI, 1.32–4.06 points) was observed (SGG and TGG, respectively) in the SPPB test; as well as an increase of 5.28 points (95%CI, 0.70–9.76 points) in the Barthel Index and 2.03 kg (95%CI, 0.33–3.72 kg) in handgrip strength in the TGG. Regression mediation analyses demonstrated that muscle strength changes (β = 1.30; 95%CI, 0.45–2.14; indirect effect 0.864; 95%CI, 0.09–1.90) significantly mediated the TGG effect on the SPPB score. Conclusions: The TGG intervention programme may provide significant benefits in physical and muscle function over usual care and seems to reverse the functional decline frequently associated with acute hospitalisation in older adults.

Spanish HTT gene study reveals haplotype and allelic diversity with possible implications for germline expansion dynamics in Huntington disease
(Oxford University Press, 2023) Ruiz de Sabando, Ainara; Urrutia Lafuente, Edurne; Galbete Jiménez, Arkaitz; Ciosi, Marc; García Amigot, Fermín; García Solaesa, Virginia; Monckton, Darren G.; Ramos Arroyo, María A.; Ciencias de la Salud; Osasun Zientziak; Estadística, Informática y Matemáticas; Estatistika, Informatika eta Matematika
We aimed to determine the genetic diversity and molecular characteristics of the Huntington disease (HD) gene (HTT) in Spain. We performed an extended haplotype and exon one deep sequencing analysis of the HTT gene in a nationwide cohort of population-based controls (n = 520) and families with symptomatic individuals referred for HD genetic testing. This group included 331 HD cases and 140 carriers of intermediate alleles. Clinical and family history data were obtained when available. Spanish normal alleles are enriched in C haplotypes (40.1%), whereas A1 (39.8%) and A2 (31.6%) prevail among intermediate and expanded alleles, respectively. Alleles ≥ 50 CAG repeats are primarily associated with haplotypes A2 (38.9%) and C (32%), which are also present in 50% and 21.4%, respectively, of HD families with large intergenerational expansions. Non-canonical variants of exon one sequence are less frequent, but much more diverse, in alleles of ≥27 CAG repeats. The deletion of CAACAG, one of the six rare variants not observed among smaller normal alleles, is associated with haplotype C and appears to correlate with larger intergenerational expansions and early onset of symptoms. Spanish HD haplotypes are characterized by a high genetic diversity, potentially admixed with other non-Caucasian populations, with a higher representation of A2 and C haplotypes than most European populations. Differences in haplotype distributions across the CAG length range support differential germline expansion dynamics, with A2 and C showing the largest intergenerational expansions. This haplotype-dependent germline instability may be driven by specific cis-elements, such as the CAACAG deletion.

Fundamento. El objetivo de este estudio es describir los traumas graves (TG) en Navarra y analizar sus diferencias por mortalidad, sexo y mecanismo lesional. Material y métodos. Estudio transversal de TG (gravedad ≥3) registrados en Navarra desde 2010 a 2019. Se analizó el tipo de TG, su intencionalidad, mecanismo y región anatómica afectada. Se calculó el riesgo (OR) de TG según distintas variables. Resultados. Se incluyeron 2.609 pacientes con TG, con media de edad 54,7 años (0-101) y 70,9% varones. Predominaron los TG contusos (94,7%) y accidentales (84%) causados por caí-das (46,5%) y accidentes de coche (18,4%). Las mujeres sufrieron más caídas y atropellos y los hombres más accidentes de moto, bicicleta, arma blanca/de fuego y contusiones. La mayoría de TG se registraron en cabeza y tórax. Las lesiones en cabeza fueron significativamente más frecuentes en fallecidos y en mujeres, y las lesiones en tórax en personas fallecidas in situ y en hombres. Las causas más frecuentes de TG en cabeza fueron caídas de baja altura y armas de fuego y, en tórax, los accidentes de coche y las caídas de altura. El riesgo de TG disminuyó con la edad y se multiplicó por 2-3 en pacientes fallecidos. Conclusión. Se han identificado diferencias por sexo en intencionalidad, tipo de traumatismo y mecanismo del TG. Globalmente, las lesiones en cabeza y tórax son más letales, y las abdominales y de extremidades/anillo pélvico se observaron en muertes tempranas, sugiriendo una afectación tan extensa y grave que dificulta su tratamiento y manejo.

Postoperative physical rehabilitation in the elderly patient after emergency surgery: influence on functional, cognitive and quality of live recovery: study protocol for a randomized clinical trial
(BMC, 2024) Esquiroz Lizaur, Irene; Zambom Ferraresi, Fabrício; Zambom Ferraresi, Fabíola; Ollo Martínez, Iranzu; Casa Marín, Antón de la; Martínez Velilla, Nicolás; Recreo Baquedano, Ana; Galbete Jiménez, Arkaitz; González Álvarez, Gregorio; Yárnoz Irazábal, María Concepción; Eguaras Córdoba, Inés; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Background: the progressive aging of the population has meant the increase in elderly patients requiring an urgent surgery. Older adults, especially those with frailty, have a higher risk for complications, functional and cognitive decline after urgent surgery. These patients have their functional and physiological reserve reduced which makes them more vulnerable to the effects of being bedridden. The consequences are at multiple levels emphasizing the functional loss or cognitive impairment, longer stays, mortality and institutionalization, delirium, poor quality of life and increased use of resources related to health. We aim to determine whether postoperative physical rehabilitation can prevent functional and cognitive decline and modify the posterior trajectory. Methods/design: this study is a randomized clinical trial, simple blinded, conducted in the Department of Surgery of a tertiary public hospital in Navarra (Hospital Universitario de Navarra), Spain. Patients > = 70 years old undergoing urgent abdominal surgery who meet inclusion criteria will be randomly assigned to the intervention or control group. The intervention will consist of a multicomponent physical training programme, which will include progressive and supervised endurance, resistance and balance training for 4 weeks, twice weekly sessions with a total of 8 sessions, and the group control will receive the usual care. The primary outcome measure is the change in functional (SPPB) and cognitive status (Mini-Mental State Examination) and the change of quality of life (EuroQol-5D-VAS) during the study period. The secondary outcomes are postoperative complications, length of stay, delirium, mortality, use of health resources, functional status (Barthel Index and handgrip strength tests), cost per quality-adjusted life year and mininutritional assessment. The data for both the intervention group and the control group will be obtained at four different times: the initial visit during hospital admission and at months 1, 3 and 6 months after hospital discharge. Discussion: If our hypothesis is correct, this project could show that individualized and progressive exercise programme provides effective therapy for improving the functional capacity and achieve a better functional, cognitive and quality of life recovery. This measure, without entailing a significant expense for the administration, probably has an important repercussion both in the short- and long-term recovery, improving care and functional parameters and could determine a lower subsequent need for health resources. To verify this, we will carry out a cost-effectiveness study. The clinical impact of this trial can be significant if we help to modify the traditional management of the elderly patients from an illness model to a more person-centred and functionally oriented perspective. Moreover, the prescription of individualized exercise can be routinely included in the clinical practice of these patients. Trial registration: ClinicalTrials.gov Identifier: NCT05290532. Version 1.

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.

(Wiley, 2025-02-18) Roncal Belzunce, Victoria; Gutiérrez Valencia, Marta; Cedeño Veloz, Bernardo Abel; San Miguel Elcano, Ramón; Marín Epelde, Itxaso; Galbete Jiménez, Arkaitz; Preciado Goldaracena, Javier; Ezpeleta, María Irache; Garaioa-Aramburu, Karmele; Martínez Velilla, Nicolás; Ciencias de la Salud; Osasun Zientziak
Objectives: The increase in polypharmacy among older adults increases the risk of drug-related problems, making multidisci-plinary interventions essential. This study evaluated the impact of a multidisciplinary polypharmacy consultation on medicationmanagement and outcomes in older outpatients.Methods: This prospective observational study at a Spanish teaching hospital involved geriatricians, clinical pharmacists, andnurses. Older adults (≥ 75 years) with polypharmacy underwent medication review at baseline and at 3 and 6 months. Data onmedication use, adherence to Screening Tool of Older Person's Prescriptions (STOOP) criteria, and anticholinergic burden wereanalyzed.Results: The study included 104 older adults (mean age 86.2 years; 66% female). An average of 3.6 recommendations per par-ticipant was made (63.8% acceptance rate). Common drug-related problems were adverse effects (20%), non-adherence (18.1%), and incorrect dose/regimen (14.4%). Interventions led to an average reduction of 1.7 medications per patient, with 1.3 dosage orregimen changes and 1.1 new prescriptions. The mean number of medications decreased from 9.6 at baseline to 8.9 at 3 months(p < 0.001) and remained below baseline at 6 months. STOPP criteria violations per patient dropped from 1.2 to 1.0 (p = 0.036). Of the 126 medications flagged by STOPP criteria, 68.3% were addressed, 24.6% discontinued, mainly psychotropics, and 89.3%of these discontinuations were maintained. The anticholinergic burden decreased from 1.3 to 1.1 at 3 months (p = 0.036) andremained below baseline at 6 months.Conclusions: A multidisciplinary clinic effectively managed polypharmacy in older adults by reducing medication load andimproving appropriateness per STOPP criteria, highlighting the importance of proactive medication management.Trial Registration: ClinicalTrials.gov: NCT05408598 (March 1, 2022).

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.

Specific multimorbidity patterns modify the impact of an exercise intervention in older hospitalized adults
(SAGE, 2022) Martínez Velilla, Nicolás; Galbete Jiménez, Arkaitz; Roso Llorach, Albert; Zambom Ferraresi, Fabrício; López Sáez de Asteasu, Mikel; Izquierdo Redín, Mikel; Vetrano, Davide L.; Calderón Larrañaga, Amaia; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua
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.
