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.

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.

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.

Background: Acute illness requiring hospitalization frequently is a sentinel event leading to long-term disability in older people. Prolonged bed rest increases the risk of developing cognitive impairment and dementia in acutely hospitalized older adults. Exercise protocols applied during acute hospitalization can prevent functional decline in older patients, but exercise benefits on specific cognitive domains have not been previously investigated. We aimed to assess the effects of a multicomponent exercise intervention for cognitive function in older adults during acute hospitalization. Methods and findings: We performed a secondary analysis of a single-blind randomized clinical trial (RCT) conducted from February 1, 2015, to August 30, 2017 in an Acute Care of the Elderly (ACE) unit in a tertiary public hospital in Navarre (Spain). 370 hospitalized patients (aged ≥75 years) were randomly allocated to an exercise intervention (n = 185) or a control (n = 185) group (usual care). The intervention consisted of a multicomponent exercise training program performed during 5–7 consecutive days (2 sessions/day). The usual care group received habitual hospital care, which included physical rehabilitation when needed. The main outcomes were change in executive function from baseline to discharge, assessed with the dual-task (i.e., verbal and arithmetic) Gait Velocity Test (GVT) and the Trail Making Test Part A (TMT-A). Changes in the Mini Mental State Examination (MMSE) test and verbal fluency ability were also measured after the intervention period. The physical exercise program provided significant benefits over usual care. At discharge, the exercise group showed a mean increase of 0.1 m/s (95% confidence interval [CI], 0.07, 0.13; p < 0.001) in the verbal GVT and 0.1 m/s (95% CI, 0.08, 0.13; p < 0.001) in the arithmetic GVT over usual care group. There was an apparent improvement in the intervention group also in the TMT-A score (−31.1 seconds; 95% CI, −49.5, −12.7 versus −3.13 seconds; 95% CI, −16.3, 10.2 in the control group; p < 0.001) and the MMSE score (2.10 points; 95% CI, 1.75, 2.46 versus 0.27 points; 95% CI, −0.08, 0.63; p < 0.001). Significant benefits were also observed in the exercise group for the verbal fluency test (mean 2.16 words; 95% CI, 1.56, 2.74; p < 0.001) over the usual care group. The main limitations of the study were patients’ difficulty in completing all the tasks at both hospital admission and discharge (e.g., 25% of older patients were unable to complete the arithmetic GVT, and 47% could not complete the TMT-A), and only old patients with relatively good functional capacity at preadmission (i.e., Barthel Index score ≥60 points) were included in the study. Conclusions: An individualized, multicomponent exercise training program may be an effective therapy for improving cognitive function (i.e., executive function and verbal fluency domains) in very old patients during acute hospitalization. These findings support the need for a shift from the traditional (bedrest-based) hospitalization to one that recognizes the important role of maintaining functional capacity and cognitive function in older adults, key components of intrinsic capacity.

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.

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.

(Springer Nature, 2024) Ruiz de Sabando, Ainara; Ciosi, Marc; Galbete Jiménez, Arkaitz; Cumming, Sarah A.; Monckton, Darren G.; Ramos Arroyo, María A.; Álvarez, Victoria; Martínez-Descals, Asunción; Mila, Montserrat; Trujillo-Tiebas, María José; López-Sendón, José Luis; Fenollar-Cortés, María; Legarda, Inés; Bernal Noguera, Sara; Millán, J.

Huntington disease (HD) is a neurodegenerative disorder caused by ≥36 CAGs in the HTT gene. Intermediate alleles (IAs) (27–35 CAGs) are not considered HD-causing, but their potential association with neurocognitive symptoms remains controversial. As HTT somatic CAG expansion influences HD onset, we hypothesised that IAs are somatically unstable, and that somatic CAG expansion may drive phenotypic presentation in some IA carriers. We quantified HTT somatic CAG expansions by MiSeq sequencing in the blood DNA of 164 HD subjects and 191 IA (symptomatic and control) carriers, and in the brain DNA of a symptomatic 33 CAG carrier. We also performed genotype-phenotype analysis. The phenotype of symptomatic IA carriers was characterised by motor (85%), cognitive (27%) and/or behavioural (29%) signs, with a late (58.7 ± 18.6 years), but not CAG-dependent, age at onset. IAs displayed somatic expansion that were CAG and age-dependent in blood DNA, with 0.4% and 0.01% of DNA molecules expanding by CAG and year, respectively. Somatic expansions of +1 and +2 CAGs were detected in the brain of the individual with 33 CAGs, with the highest expansion frequency in the putamen (10.3%) and the lowest in the cerebellum (4.8%). Somatic expansion in blood DNA was not different in symptomatic vs. control IA carriers. In conclusion, we show that HTT IAs are somatically unstable, but we found no association with HD-like phenotypes. It is plausible, however, that some IAs, close to the HD pathological threshold and with a predisposing genetic background, could manifest with neurocognitive symptoms.

(Sociedad Gallega de Medicina Interna, 2021) Ruiz Sada, Pablo; Sampériz Legarre, Ángel; Palacios García, Lara; Galbete Jiménez, Arkaitz; Tiberio López, Gregorio; Ciencias de la Salud; Osasun Zientziak
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.

Dose-response relationship between exercise duration and enhanced function and cognition in acutely hospitalized older adults: a secondary analysis of a randomized clinical Trial
(Oxford University Press, 2024-06-01) López Sáez de Asteasu, Mikel; Martínez Velilla, Nicolás; Zambom Ferraresi, Fabrício; Galbete Jiménez, Arkaitz; Ramírez Vélez, Robinson; Lusa Cadore, Eduardo; Abizanda, Pedro; Gómez-Pavón, Javier; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Estadística, Informática y Matemáticas; Estatistika, Informatika eta Matematika; Institute of Smart Cities - ISC; Gobierno de Navarra / Nafarroako Gobernua
Background and objectives: exercise may reverse functional decline in hospitalized older adults, but the optimal duration is unclear. This study examined the potential relationship between in-hospital multicomponent exercise program duration and changes in physical function, cognition, and muscle function to maximize exercise-related health benefits in acutely hospitalized older patients. Research design and methods: this secondary analysis of a multicenter randomized controlled trial examined the relationship between the duration of an in-hospital multicomponent exercise program and changes in physical function, cognition, and muscle strength in 570 acutely hospitalized older adults. Participants completed 3, 4, or 5-7 consecutive days of exercise based on the progression of their acute medical illness. The acute clinical condition of the older patients was similar across the study groups (i.e., 3/4/5-7 days) at admission. Outcomes included the Short Physical Performance Battery (SPPB) for functional capacity, Gait Velocity Test for gait speed, handgrip for muscle strength, and cognitive tests. Results: of the 570 patients included in the analysis, 298 were women (52.3%), and the mean (SD) age was 87.3 (4.8) years. Exercise groups increased SPPB scores compared with controls, with gains of 1.09 points after three days, 1.97 points after four days, and 2.02 points after 5-7 days (p < .001). The 4-day program showed the most significant benefit for functional capacity. Gait velocity increased by 0.11 m/s after 4 and 5-7 days (p = .032). Similar dose-response relationships were seen for handgrip strength and cognition, with 5-7 days showing more significant gains than three days (p < .05). Discussion and implications: multicomponent exercise programs enhance physical and cognitive function in hospitalized older adults, regardless of exercise dosage. A 4-day program significantly boosts functional capacity, although 5-7 days improves handgrip strength and cognition, highlighting the importance of exercise dosage in countering functional decline. Implementing evidence-based inpatient exercise prescriptions can help reverse muscle weakness and improve cognitive and physical function.
