Somatic CAG repeat instability in intermediate alleles of the HTT gene and its potential association with a clinical phenotype.

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.

Sex-dependent effect of socioeconomic status on cardiovascular event risk in a population-based cohort of patients with type 2 diabetes.

BACKGROUND: Socioeconomic status (SES) factors often result in profound health inequalities among populations, and their impact may differ between sexes. The aim of this study was to estimate and compare the effect of socioeconomic status indicators on incident cardiovascular disease (CVD)-related events among males and females with type 2 diabetes (T2D). METHODS: A population-based cohort from a southern European region including 24,650 patients with T2D was followed for five years. The sex-specific associations between SES indicators and the first occurring CVD event were modeled using multivariate Fine-Gray competing risk models. Coronary Heart Disease (CHD) and stroke were considered secondary outcomes. RESULTS: Patients without a formal education had a significantly higher risk of CVD than those with a high school or university education, with adjusted hazard ratios (HRs) equal to 1.24 (95%CI: 1.09-1.41) for males and 1.50 (95%CI: 1.09-2.06) for females. Patients with <18 000€ income had also higher CVD risk than those with ≥18 000€, with HRs equal to 1.44 (95%CI: 1.29-1.59) for males and 1.42 (95%CI: 1.26-1.60) for females. Being immigrant showed a HR equal to 0.81 (95%CI: 0.66-0.99) for males and 1.13 (95%CI: 0.68-1.87) for females. Similar results were observed for stroke, but differed for CHD when income is used, which had higher effect in females. CONCLUSION: Socioeconomic inequalities in CVD outcomes are present among T2D patients, and their magnitude for educational attainment is sex-dependent, being higher in females, suggesting the need to consider them when designing tailored primary prevention and management strategies.

Efficacy of different 8 h time-restricted eating schedules on visceral adipose tissue and cardiometabolic health: A study protocol.

BACKGROUND AND AIMS: To investigate the efficacy and feasibility of three different 8 h time-restricted eating (TRE) schedules (i.e., early, late, and self-selected) compared to each other and to a usual-care (UC) intervention on visceral adipose tissue (VAT) and cardiometabolic health in men and women. METHODS AND RESULTS: Anticipated 208 adults (50% women) aged 30-60 years, with overweight/obesity (25 ≤ BMI<40 kg/m2) and with mild metabolic impairments will be recruited for this parallel-group, multicenter randomized controlled trial. Participants will be randomly allocated (1:1:1:1) to one of four groups for 12 weeks: UC, early TRE, late TRE or self-selected TRE. The UC group will maintain their habitual eating window and receive, as well as the TRE groups, healthy lifestyle education for weight management. The early TRE group will start eating not later than 10:00, and the late TRE group not before 13:00. The self-selected TRE group will select an 8 h eating window before the intervention and maintain it over the intervention. The primary outcome is changes in VAT, whereas secondary outcomes include body composition and cardiometabolic risk factors. CONCLUSION: This study will determine whether the timing of the eating window during TRE impacts its efficacy on VAT, body composition and cardiometabolic risk factors and provide insights about its feasibility.

Cognitive and functional trajectories in geriatric outpatients after a pharmacologic multidisciplinary intervention: A study protocol / Trayectorias cognitivas y funcionales en pacientes ambulatorios geriátricos tras una intervención farmacológica multidisciplinar: protocolo de estudio

Background Polypharmacy is a common condition among older adults and is associated with adverse drug reactions and health outcomes, including falls, functional and cognitive impairment, and frailty. Methods A prospective observational study will be conducted on older adults with polypharmacy. The aim is to assess the impact of a specialized outpatient clinic focused on pharmacotherapy optimization recently integrated into daily clinical practice in a Spanish public tertiary teaching hospital on patients’ functional and cognitive abilities. Patients who attend a first consultation and meet inclusion criteria (≥75 years old, have a life expectancy≥3 months, and polypharmacy (≥5 prescribed medications) will be invited to participate in the study, until reach a calculated sample size of 104 participants. Patients will be excluded if they are enrolled in a clinical trial related to medication or in the event of a no-show or cancellation of the appointment at the first visit. Participants will receive usual care: a first consultation including multidisciplinary pharmacological optimization in the context of a CGA and subsequent face-to-face and/or telephone follow-up (∼3 and ∼6 months). The primary endpoint will be the functional (Barthel index) and cognitive change in capacities (IPCR – Índice de Incapacidad psíquica de la Cruz Roja). Secondary endpoints include medication changes, changes in patients’ quality of life, rate of falling, and use of healthcare resources. Discussion We expect that the close collaboration between professionals from different disciplines working together will be an effective strategy to improve the functional and cognitive abilities of older adults.

Epidemiology of severe trauma in Navarra for 10 years: out-of-hospital/ in-hospital deaths and survivors.

BACKGROUND: Major trauma is a leading cause of death. Due to the difficulties to keep a registry of these cases, few studies include all subjects, because they exclude out-of-hospital deaths. The purpose of this work was to compare the epidemiological profiles of out-of-hospital deaths, in-hospital deaths, and survivors over a 10-year period (2010-2019) of patients who had been treated by Navarre´s Health Service (Spain). METHODS: Retrospective longitudinal cohort study using data of patients injured by an external physical force of any intentionality and with a New Injury Severity Score above 15. Hangings, drownings, burns, and chokings were excluded. Intergroup differences of demographic and clinical variables were analysed using the Kruskal Wallis test, chi-squared test, or Fisher´s exact test. RESULTS: Data from 2,610 patients were analysed; 624 died out-of-hospital, 439 in-hospital, and 1,547 survived. Trauma incidences remained moderately stable over the 10-year period analysed, with a slight decrease in out-of-hospital deaths and a slight increase in in-hospital deaths. Patients of the out-of-hospital deaths group were younger (50.9 years) in comparison to in-hospital deaths and survivors. Death victims were predominantly male in all study groups. Intergroup differences regarding prior comorbidities and predominant type of injury were observed. CONCLUSIONS: There are significant differences among the three study groups. More than half of the deaths occur out-of-hospital and the causative mechanisms differ in each of them. Thus, when designing strategies, preventive measures were considered for each group on a case-by-case basis.

Cohort Profile: CArdiovascular Risk in patients with DIAbetes in NAvarra (CARDIANA cohort).

PURPOSE: The CArdiovascular Risk in patients with DIAbetes in Navarra (CARDIANA cohort) cohort was established to assess the effects of sociodemographic and clinical variables on the risk of cardiovascular events in patients with type 1 (T1D) or type 2 (T2D) diabetes, with a special focus on socioeconomic factors, and to validate and develop cardiovascular risk models for these patients. PARTICIPANTS: The CARDIANA cohort included all patients with T1D and T2D diabetes registered in the Public Health Service of Navarra with prevalent disease on 1 January 2012. It consisted of 1067 patients with T1D (ages 2-88 years) and 33842 patients with T2D (ages 20-105 years), whose data were retrospectively extracted from the Health and Administrative System Databases. FINDINGS TO DATE: The follow-up period for wave 1 was from 1 January 2012 to 31 December 2016. During these 5 years, 9 patients (0.8%; 95% CI (0.4% to 1.6%)) in the T1D cohort developed a cardiovascular disease event, whereas for the T2D cohort, 2602 (7.7%; 95% CI (7.4% to 8.0%)) had an event. For the T2D cohort, physical activity was associated with a reduced risk of cardiovascular events, with adjusted estimated ORs equal to 0.84 (95% CI 0.66 to 1.07) for the partially active group and 0.71 (95% CI 0.56 to 0.91) for the active group, compared with patients in the non-active group. FUTURE PLANS: The CARDIANA cohort is currently being used to assess the effect of sociodemographic risk factors on CV risk at 5 years and to externally validate cardiovascular predictive models. A second wave is being conducted in late 2022 and early 2023, to extend the follow-up other 5 years, from 1 January 2016 to 31 December 2021. Periodic data extractions are planned every 5 years.

Spanish HTT gene study reveals haplotype and allelic diversity with possible implications for germline expansion dynamics in Huntington disease.

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.

Specific multimorbidity patterns modify the impact of an exercise intervention in older hospitalized adults.

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.

Profile and 3-month evolution of geriatric patients after a hip fracture followed-up at a Fracture Liaison Service (FLS).

INTRODUCTION: There are few studies on Fracture Liaison Service (FLS) that evaluate older patients after a hip fracture (HF) through comprehensive geriatric assessment. We aim to determine these patients' characteristics, outcomes, and prescribed treatments. METHODS: A retrospective observational study of a cohort of patients older than 65 years admitted with HFs to an orthogeriatric unit between February 25th (2013) and December 16th (2016). After hospitalization, those patients with a good baseline social, functional, and cognitive situation were referred to the FLS. A comprehensive geriatric assessment and treatment adjustment were conducted. A comparison between FLS patients and HF patients non-referred was made. RESULTS: From 1887 patients admitted to the orthogeriatric unit, 469 (23%) were referred to the FLS. Of those, 335 were women (77.2%) and 337 (77.6%) lived in the community. The FLS patients had a better functional status (97.1% of the patients with independent gait versus 79.2%) than non-FLS patients (p<0.001). After 3 months in the FLS, 356 (82%) patients had independent gait and had improved their analytical values. Antiosteoporotic treatment was prescribed to 322 patients (74%), vitamin D supplements to 397 (91.5%), calcium to 321 (74%), and physical exercise to 421 (97%). CONCLUSIONS: Patients referred to an FLS were younger, with a better functional and cognitive situation. At hospital discharge, they frequently presented gait impairment and laboratory abnormalities (anemia, hypoproteinemia, vitamin D deficiency) that presented good recovery due to the patient's previous baseline. These patients benefit from comprehensive treatment (pharmacological and non-pharmacological).

Prostatic Artery Embolization (PAE) Using Polyethylene Glycol Microspheres: Safety and Efficacy in 81 Patients.

PURPOSE: To evaluate the safety and efficacy of prostatic artery embolization (PAE) using polyethylene glycol microspheres (PEGM) in patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: This multicentric prospective study enrolled 81 patients who underwent PAE with 400 ± 75 µm PEGM (HydroPearl®, Terumo, Japan). Results from baseline and 1-, 3-, 6-, and 12-month follow-ups were assessed for subjective outcomes including International Prostate Symptoms Score (IPSS), Quality of life (QoL), and International Index of Erectile Function, and objective outcomes such as peak urinary flow (Qmax) and post-void residual volume (PVR). The visual analogue scale, satisfaction questionnaire, prostatic volume, and prostatic specific antigen levels were also evaluated. Complications were documented using the modified Clavien-Dindo classification. RESULTS: Technical success was obtained in all patients. Clinical success was achieved in 78.5% of patients. Before PAE, 54.3% of patients had an indwelling catheter which was removed in 75% of them after procedure. A statistically significant decrease was observed in IPSS and QoL from baseline to 12 months (20.14 vs 5.89; 4.8 vs 0.63, P < .01), respectively. Objective outcomes also showed a statistically significant improvement in Qmax (+ 114.9%; P < .01), achieving a maximum urinary flow of 14.2 mL/sec, and PVR (decrease 58%; P < .05) at 12 months. Minor complications (Clavien-Dindo grades I-II) occurred in 13.6% of patients, without major complications observed. CONCLUSION: PAE with PEGM is safe and effective treatment in patients with symptomatic BPH, with a significant improvement in both subjective and objective outcomes.

Lesiones residuales en radiografía simple de tórax tras neumonía por SARS-CoV-2: identificación de factores de riesgo / Residual lesions on chest-Xray after SARS-CoV-2 pneumonia: Identification of risk factors

Introducción:La neumonía por la enfermedad por el coronavirus 19 (COVID-19) es la manifestación clínica más frecuente de esta afección, siendo aún desconocidas sus secuelas a largo plazo y la posible evolución a fibrosis pulmonar. El objetivo de este trabajo es una revisión a medio plazo de las secuelas en la radiografía simple de tórax (RxTx) de pacientes con diagnóstico previo de neumonía por la COVID-19.Pacientes y métodos:Revisión retrospectiva de pacientes con diagnóstico de neumonía por la COVID-19 en la que hemos valorado la persistencia de lesiones residuales en la RxTx de control y hemos analizado su posible relación con factores epidemiológicos, factores de riesgo, tratamientos recibidos y patrones radiológicos iniciales.Resultados:Se analizan 143 pacientes (52 mujeres y 91 hombres), con una edad media de 64 años. Se objetivó una resolución completa radiológica en 104 (73%) y resolución parcial en 39 (27%). De los factores de riesgo solo la edad se relacionó significativamente con la persistencia de lesiones residuales (OR: 1,06; IC 95%: 1,02-1,10). En relación con los tratamientos se encontraron diferencias significativas con el tocilizumab y los glucocorticoides, donde los pacientes tratados tenían más riesgo de lesiones residuales (OR 2,44 [1,03; 5,80] y 3,05 [1;43; 6,51]) respectivamente. En el análisis de los patrones radiológicos se observaron diferencias significativas en los pacientes que presentaban en la evolución aguda condensaciones periféricas y un patrón de empeoramiento radiológico precoz. Se evidenció una disociación clínico-radiológica: de los pacientes con lesiones residuales un 83% no tenía síntomas respiratorios.Discusión:Las neumonías por la COVID-19 pueden tener una resolución radiológica más lenta en pacientes de mayor edad y con ciertos patrones radiológicos iniciales, pero el desarrollo de fibrosis pulmonar en estos pacientes es un hecho aún cuestionable.

Introduction:COVID-19 pneumonia is the most frequent clinical manifestation of this disease, and its long-term sequelae and possible progression to pulmonary fibrosis are still unknown. The aim of this study is a mid-term review of the sequelae on plain chest radiography (CXR) in patients with a previous diagnosis of COVID-19 pneumonia.Patients and methods:Retrospective review of patients with a diagnosis of COVID-19 pneumonia, assessing the persistence of residual lesions in the control CXR and analysing their possible relationship with epidemiological factors, risk factors, treatments received and initial radiological patterns.Results:A total of 143 patients (52 women and 91 men) were analysed. Mean age was 64 years. Radiological complete resolution (CR) was observed in 104 (73%) and partial resolution (PR) in 39 (27%). Of the risk factors only age was significantly related to persistence of residual lesions (OR 1.06 CI 95% (1.02,1.10). In relation to treatments, significant differences were found with tocilizumab and glucocorticoids, where treated patients had a higher risk of residual lesions (OR 2.44 (1.03,5.80) and 3.05(1.43,6.51) respectively. In the analysis of radiological patterns, significant differences were observed in patients with peripheral condensations in the acute course and a pattern of early radiological worsening. A clinical-radiological dissociation was evident: 83% of patients with residual lesions had no respiratory symptoms.Discussion:COVID19 pneumonias may have a slower radiological resolution in older patients with certain initial radiological patterns, but the development of pulmonary fibrosis in these patients is still questionable.

Development of a prediction protocol for the screening of metabolic associated fatty liver disease in children with overweight or obesity.

BACKGROUND: The early detection and management of children with metabolic associated fatty liver disease (MAFLD) is challenging. OBJECTIVE: To develop a non-invasive and accurate prediction protocol for the identification of MAFLD among children with overweight/obesity candidates to confirmatory diagnosis. METHODS: A total of 115 children aged 8-12 years with overweight/obesity, recruited at a primary care, were enrolled in this cross-sectional study. The external validation was performed using a cohort of children with overweight/obesity (N = 46) aged 8.5-14.0 years. MAFLD (≥5.5% hepatic fat) was diagnosed by magnetic resonance imaging (MRI). Fasting blood biochemical parameters were measured, and 25 candidates' single nucleotide polymorphisms (SNPs) were determined. Variables potentially associated with the presence of MAFLD were included in a multivariate logistic regression. RESULTS: Children with MAFLD (36%) showed higher plasma triglycerides (TG), insulin, homeostasis model assessment of insulin resistance (HOMA-IR), alanine aminotransferase (ALT), aspartate transaminase (AST), glutamyl-transferase (GGT) and ferritin (p < 0.05). The distribution of the risk-alleles of PPARGrs13081389, PPARGrs1801282, HFErs1800562 and PNLPLA3rs4823173 was significantly different between children with and without MAFLD (p < 0.05). Three biochemical- and/or SNPs-based predictive models were developed, showing strong discriminatory capacity (AUC-ROC: 0.708-0.888) but limited diagnostic performance (sensitivity 67%-82% and specificity 63%-69%). A prediction protocol with elevated sensitivity (72%) and specificity (84%) based on two consecutive steps was developed. The external validation showed similar results: sensitivity of 70% and specificity of 85%. CONCLUSIONS: The HEPAKID prediction protocol is an accurate, easy to implant, minimally invasive and low economic cost tool useful for the early identification and management of paediatric MAFLD in primary care.

Pacientes y métodos: Revisión retrospectiva de pacientes con diagnóstico de neumonía por la COVID-19 en la que hemos valorado la persistencia de lesiones residuales en la RxTx de control y hemos analizado su posible relación con factores epidemiológicos, factores de riesgo, tratamientos recibidos y patrones radiológicos iniciales. Resultados: Se analizan 143 pacientes (52 mujeres y 91 hombres). Edad media de 64 años. Se objetivó una resolución completa (RC) radiológica en 104 (73%) y resolución parcial (RP) en 39 (27%). De los factores de riesgo sólo la edad se relacionó significativamente con la persistencia de lesiones residuales (OR 1.06 IC95% (1.02,1.10). En relación con los tratamientos se encontraron diferencias significativas con el tocilizumab y glucocorticoides, donde los pacientes tratados tenían más riesgo de lesiones residuales (OR 2.44 (1.03,5.80) y 3.05(1.43,6.51) respectivamente. En el análisis de los patrones radiológicos se observaron diferencias significativas en los pacientes que presentaban en la evolución aguda condensaciones periféricas y un patrón de empeoramiento radiológico precoz. Se evidenció una disociación clínico-radiológica: de los pacientes con lesiones residuales un 83% no tenían síntomas respiratorios. Discusión: Las neumonías por COVID19 pueden tener una resolución radiológica más lenta en pacientes de mayor edad y con ciertos patrones radiológicos iniciales, pero el desarrollo de fibrosis pulmonar en estos pacientes es un hecho aún cuestionable.

Prevalencia de anemia en población gestante / Anaemia prevalence in pregnant population

Introducción:La anemia gestacional, que tiene unos valores de referencia de hemoglobina específicos en cada trimestre de gestación, aumenta el riesgo de mortalidad materna y de complicaciones fetales y neonatales. El objetivo de este estudio es evaluar los niveles de hemoglobina en las gestantes de nuestra población y conocer la prevalencia de anemia gestacional.Material y métodos:Estudio retrospectivo de los hemogramas solicitados en los controles de gestación durante el año 2019.Resultados:Se revisaron 9.995 hemogramas de gestación correspondientes a 5.507 embarazadas, 1134 pacientes tuvieron el control evolutivo completo en 2019. Los datos de prevalencia de anemia fueron de un 1,8%, 11,8% y 13,2% en cada trimestre respectivamente. La prevalencia global fue de un 22,6%.Conclusiones:La prevalencia de anemia gestacional en nuestra población es algo superior a la consultada en la bibliografía y varía en función del cálculo del límite inferior de normalidad (hemoglobina media poblacional y criterios de normalidad clásico y de Beutler&Waalen). Esto nos pone en alerta sobre la existencia de un margen de mejora en nuestros protocolos clínicos actuales. (AU)

Introduction:Gestational anaemia, which has specific haemoglobin (Hb) reference values in each trimester of gestation, increases the risk of maternal mortality and complications both in pregnancy and in the first months of the newborn's life. The objective of this study is to evaluate haemoglobin levels in pregnant women in our population, to determine the prevalence of gestational anaemia and to propose reference values specific to them.Material and methods:Retrospective study of all blood counts requested in pregnancy and postpartum controls during 2019.Results:9995 gestation haemograms corresponding to 5507 pregnant women were reviewed. Of these, 1134 patients underwent complete follow-up in 2019. The prevalence data for anaemia were 1.8%, 11.8% and 13.2% in each trimester respectively, and the global prevalence in pregnancy was 22.6%. Regarding postpartum anaemia, its prevalence with respect to all pregnant women was 2.99%, increasing to 38.2% in those patients with complications during delivery.Conclusions:The prevalence of gestational anaemia in our population is somewhat higher than in countries like ours. Therefore, there is room for improvement in our current clinical protocols. It is important to assess updating analytical controls with other more adequate parameters to determine iron reserves, as this is the main cause of anaemia. (AU)

Is the Phenotype Designation by PSP-MDS Criteria Stable Throughout the Disease Course and Consistent With Tau Distribution?

INTRODUCTION: The MDS-PSP criteria have shown high sensitivity for the PSP diagnosis, but do not discriminate the phenotype diversity. Our purpose was to search for anatomopathological differences among PSP phenotypes resulting from the application of the MDS-PSP criteria comparing with the previous ones. METHODS: Thirty-four PSP cases from a single brain bank were retrospectively classified according to the criteria used by Respondek et al. in 2014 and the PSP-MDS criteria at 3 years (MDS-3y), 6 years (MDS-6y) and at the last clinical evaluation before death (MDS-last). Semiquantitative measurement of total, cortical and subcortical tau load was compared. For comparative analysis, PSP-Richardson syndrome and PSP postural instability were grouped (PSP-RS/PI) as well as the PSP atypical cortical phenotypes (PSP-Cx). RESULTS: Applying the Respondek's criteria, PSP phenotypes were distributed as follow: 55.9% PSP-RS/PI, 26.5% PSP-Cx, 11.8% PSP-Parkinsonism (PSP-P), and 5.9% PSP-Cerebellum. PSP-RS/PI and PSP-Cx had a higher total tau load than PSP-P; PSP-Cx showed a higher cortical tau load than PSP-RS/PI and PSP-P; and PSP-RS/PI had a higher subcortical tau load than PSP-P. Applying the MDS-3y, MDS-6y and MDS-last criteria; the PSP-RS/PI group increased (67.6, 70.6 and 70.6% respectively) whereas the PSP-Cx group decreased (8.8, and 8.8 and 11.8%). Then, only differences in total and subcortical tau burden between PSP-RS/PI and PSP-P were observed. INTERPRETATION: After the retrospective application of the new MDS-PSP criteria, total and subcortical tau load is higher in PSP-RS/PI than in PSP-P whereas no other differences in tau load between phenotypes were found, as a consequence of the loss of phenotypic diversity.

Effects of Vivifrail multicomponent intervention on functional capacity: a multicentre, randomized controlled trial.

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.
