NeuroVoz: a Castillian Spanish corpus of parkinsonian speech
The advancement of Parkinson's Disease (PD) diagnosis through speech analysis
is hindered by a notable lack of publicly available, diverse language datasets,
limiting the reproducibility and further exploration of existing research.
In response to this gap, we introduce a comprehensive corpus from 108 native
Castilian Spanish speakers, comprising 55 healthy controls and 53 individuals
diagnosed with PD, all of whom were under pharmacological treatment and
recorded in their medication-optimized state. This unique dataset features a
wide array of speech tasks, including sustained phonation of the five Spanish
vowels, diadochokinetic tests, 16 listen-and-repeat utterances, and free
monologues. The dataset emphasizes accuracy and reliability through specialist
manual transcriptions of the listen-and-repeat tasks and utilizes Whisper for
automated monologue transcriptions, making it the most complete public corpus
of Parkinsonian speech, and the first in Castillian Spanish.
NeuroVoz is composed by 2,903 audio recordings averaging
recordings per participant, offering a substantial resource for the scientific
exploration of PD's impact on speech. This dataset has already underpinned
several studies, achieving a benchmark accuracy of 89% in PD speech pattern
identification, indicating marked speech alterations attributable to PD.
Despite these advances, the broader challenge of conducting a
language-agnostic, cross-corpora analysis of Parkinsonian speech patterns
remains an open area for future research. This contribution not only fills a
critical void in PD speech analysis resources but also sets a new standard for
the global research community in leveraging speech as a diagnostic tool for
neurodegenerative diseases.Comment: Preprint versio

Implantation of CPT1AM-expressing adipocytes reduces obesity and glucose intolerance in mice
Obesity and its associated metabolic comorbidities are a rising global health and social issue, with novel therapeutic approaches urgently needed. Adipose tissue plays a key role in the regulation of energy balance and adipose tissue-derived mesenchymal stem cells (AT-MSCs) have gained great interest in cell therapy. Carnitine palmitoyltransferase 1A (CPT1A) is the gatekeeper enzyme for mitochondrial fatty acid oxidation. Here, we aimed to generate adipocytes expressing a constitutively active CPT1A form (CPT1AM) that can improve the obese phenotype in mice after their implantation. AT-MSCs were differentiated into mature adipocytes, subjected to lentivirus-mediated expression of CPT1AM or the GFP control, and subcutaneously implanted into mice fed a high-fat diet (HFD). CPT1AM-implanted mice showed lower body weight, hepatic steatosis and serum insulin and cholesterol levels alongside improved glucose tolerance. HFD-induced increases in adipose tissue hypertrophy, fibrosis, inflammation, endoplasmic reticulum stress and apoptosis were reduced in CPT1AM-implanted mice. In addition, the expression of mitochondrial respiratory chain complexes was enhanced in the adipose tissue of CPT1AM-implanted mice. Our results demonstrate that implantation of CPT1AM-expressing AT-MSC-derived adipocytes into HFD-fed mice improves the obese metabolic phenotype, supporting the future clinical use of this ex vivo gene therapy approach
Response to Novel Drugs before and after Allogeneic Stem Cell Transplantation in Patients with Relapsed Multiple Myeloma
Multiple myeloma (MM) remains as an incurable disease and, although allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative approach, most patients ultimately relapse, and their treatment remains challenging. Because allo-HSCT can modify not only the biology of the disease, but also the immune system and the microenvironment, it can potentially enhance the response to rescue therapies. Information on the efficacy and safety of novel drugs in patients relapsing after allo-HSCT is lacking, however. The objectives of this study were to evaluate the efficacy and toxicity of rescue therapies in patients with MM who relapsed after allo-HSCT, as well as to compare their efficacy before and after allo-HSCT. This retrospective multicenter study included 126 consecutive patients with MM who underwent allo-HSCT between 2000 and 2013 at 8 Spanish centers. All patients engrafted. The incidence of grade II-IV acute graft-versus-host disease (GVHD) was 47%, and nonrelapse mortality within the first 100 days post-transplantation was 13%. After a median follow-up of 92 months, overall survival (OS) was 51% at 2 years and 43% at 5 years. The median progression-free survival after allo-HSCT was 7 months, whereas the median OS after relapse was 33 months. Patients relapsing in the first 6 months after transplantation had a dismal prognosis compared with those who relapsed later (median OS, 11 months versus 120 months; P <.001). The absence of chronic GVHD was associated with reduced OS after relapse (hazard ratio, 3.44; P <.001). Most patients responded to rescue therapies, including proteasome inhibitors (PIs; 62%) and immunomodulatory drugs (IMiDs; 77%), with a good toxicity profile. An in-depth evaluation, including the type and intensity of PI- and IMiD-based combinations used before and after allo-HSCT, showed that the overall response rate and duration of response after allo-HSCT were similar to those seen in the pretransplantation period. Patients with MM who relapse after allo-HSCT should be considered candidates for therapy with new drugs, which can achieve similar response rates with similar durability as seen in the pretransplantation period. This pattern does not follow the usual course of the disease outside the transplantation setting, where response rates and time to progression decreases with each consecutive line of treatment
Efficacy and safety of preoperative preparation with Lugol''s iodine solution in euthyroid patients with Graves’ disease (LIGRADIS Trial): Study protocol for a multicenter randomized trial
Background: Currently, both the American Thyroid Association and the European Thyroid Association recommend preoperative preparation with Lugol''s Solution (LS) for patients undergoing thyroidectomy for Graves’ Disease (GD), but their recommendations are based on low-quality evidence. The LIGRADIS trial aims to provide evidence either to support or refute the systematic use of LS in euthyroid patients undergoing thyroidectomy for GD. Methods: A multicenter randomized controlled trial will be performed. Patients =18 years of age, diagnosed with GD, treated with antithyroid drugs, euthyroid and proposed for total thyroidectomy will be eligible for inclusion. Exclusion criteria will be prior thyroid or parathyroid surgery, hyperparathyroidism that requires associated parathyroidectomy, thyroid cancer that requires adding a lymph node dissection, iodine allergy, consumption of lithium or amiodarone, medically unfit patients (ASA-IV), breastfeeding women, preoperative vocal cord palsy and planned endoscopic, video-assisted or remote access surgery. Between January 2020 and January 2022, 270 patients will be randomized for either receiving or not preoperative preparation with LS. Researchers will be blinded to treatment assignment. The primary outcome will be the rate of postoperative complications: hypoparathyroidism, recurrent laryngeal nerve injury, hematoma, surgical site infection or death. Secondary outcomes will be intraoperative events (Thyroidectomy Difficulty Scale score, blood loss, recurrent laryngeal nerve neuromonitoring signal loss), operative time, postoperative length of stay, hospital readmissions, permanent complications and adverse events associated to LS. Conclusions: There is no conclusive evidence supporting the benefits of preoperative treatment with LS in this setting. This trial aims to provide new insights into future Clinical Practice Guidelines recommendations. Trial registration: ClinicalTrials.gov identifier: NCT03980132. © 202
Associations between eating speed, diet quality, adiposity, and cardiometabolic risk factors
Objective: To assess the associations between eating speed, adiposity, cardiometabolic risk factors, and diet quality in a cohort of Spanish preschool-children. Study design: A cross-sectional study in 1371 preschool age children (49% girls; mean age, 4.8 ± 1.0 years) from the Childhood Obesity Risk Assessment Longitudinal Study (CORALS) cohort was conducted. After exclusions, 956 participants were included in the analyses. The eating speed was estimated by summing the total minutes used in each of the 3 main meals and then categorized into slow, moderate, or fast. Multiple linear and logistic regression models were fitted to assess the β-coefficient, or OR and 95% CI, between eating speed and body mass index, waist circumference, fat mass index (FMI), blood pressure, fasting plasma glucose, and lipid profile. Results: Compared with participants in the slow-eating category, those in the fast-eating category had a higher prevalence risk of overweight/obesity (OR, 2.9; 95% CI, 1.8-4.4; P < .01); larger waist circumference (β, 2.6 cm; 95% CI, 1.5-3.8 cm); and greater FMI (β, 0.3 kg/m2; 95% CI, 0.1-0.5 kg/m2), systolic blood pressure (β, 2.8 mmHg; 95% CI, 0.6-4.9 mmHg), and fasting plasma glucose levels (β, 2.7 mg/dL, 95% CI, 1.2-4.2 mg/dL) but lower adherence to the Mediterranean diet (β, −0.5 points; 95% CI, −0.9 to −0.1 points). Conclusions: Eating fast is associated with higher adiposity, certain cardiometabolic risk factors, and lower adherence to a Mediterranean diet. Further long-term and interventional studies are warranted to confirm these associations
Escenarios de cambio climático regional en Cantabria aplicados a la cartografía agroclimática de precisión
RESUMEN: Se han elaborado para la CC.AA. de Cantabria los modelos climáticos regionales y los escenarios de cambio climático para el presente siglo con una precisión de “pixel” de 1Km, como producto de la interpolación de los datos meteorológicos al territorio a través de un SIG. Para la elaboración de dichos modelos se ha aplicado un método lineal local (regresión multivariada utilizando un conjuntode vecinos de cada punto), considerando como regresores las siguientes variables: elevación sobre el nivel del mar, su cuadrado y su cubo, longitud y latitud, insolación potencial en cinco épocas distintas del año, distancia a la costa, su cuadrado y su cubo, curvatura, calculada con radios de 5, 10 y 25 km, vertical y horizontal, y orientación, según la dirección de ocho cuadrantes. Con esta información se obtuvo el Mapa de tipos o zonas agroclimáticas de Papadakis con resolución 1x1 km. Finalmente, se ha obtenido la evolución del Mapa Agroclimático a lo largo de cuatro períodos temporales 1971– 2000, 2011–2040 y 2041–2070 y 2071–2100. Todos los procesos de cálculo están automatizados, pudiéndose generarse resultados a partir de actualizaciones o nuevos datos.ABSTRACT: Through the interpolation of meteorological data on a Geographic Information System (GIS), regional climate models (at 1 km spatial resolution) and scenarios of climate change for this century have been developed for the Cantabria Region. For the development of those models a local liner method has been used (multivariate regression using a set of neighbours at each point) considering the following variables: altitude, its square and cube, longitude, latitude, potential insolation, distance from the coast, its square and cube, topographic barriers and aspect. With this information zoning of Cantabria and the Papadakis’s Agro–climatic Map have been obtained. Finally, the evolution of the Agro–climatic Map and the potential for the selected crops have been obtained for four time periods: 1971–2000, 2011–2040, 2041–2070 and 2071–2100. GIS procedures make up to date possible when new data is available or refinements desired
Corrosion behaviour of Mg–Zn–Y–Mischmetal alloys in phosphate buffer saline solution
The influence of the processing route and chemical composition in the corrosion behaviour of two Mg-Zn-Y-Mischmetal alloys has been evaluated in phosphate buffer saline solution. The corrosion resistance of the alloy processed by conventional techniques was substantially higher than that found for the same alloy processed from atomised powders. Fine homogeneous distribution of the second-phase particles promoted severe attack due to the enhanced number of galvanic microcells. A higher concentration of zinc and a lower content of rare earth additions improved the corrosion resistance of the alloys due to the lower volume fraction of second-phase particles. © 2012 Elsevier Ltd.Peer Reviewe
