Risk of cardiovascular events is increased after COVID-19. However, information on cardiovascular risk trends after COVID-19 infection is lacking and estimates by sex are inconsistent. Our aim was to examine cardiovascular outcomes and mortality in a large cohort (164,346 participants) of SARS-CoV-2 positive individuals compared to non-positive individuals, stratified by sex. Data were obtained from the Spanish Health System’s electronic medical records. Selected individuals were ≥ 45 years old with/without a positive SARS-CoV-2 test in the period March-May 2020. Follow-up was obtained until January 31, 2021, for cardiovascular events (angina/myocardial infarction, arrhythmias, bypass/revascularization, heart failure, peripheral artery disease, stroke/transient ischemic attack, and thrombosis), and until March 31, 2021, for mortality. Individuals were matched by propensity score. Incidence of cardiovascular events and mortality was compared with accelerated failure time models. The effect of matching and of COVID-19 severity was assessed with sensitivity analyses. In the first 3 months of follow-up, SARS-CoV-2 positive individuals had a higher risk of mortality and of all cardiovascular events. From 4–12 months, there was increased risk of mortality in SARS-CoV-2 positive individuals overall, of heart failure in SARS-CoV-2 positive females (HR= 1.26 [1.11–1.42]), and of arrhythmias and thrombosis in SARS-CoV-2 positive males (HR= 1.29 [1.14–1.47] and HR= 1.35 [1.03–1.77], respectively). When COVID-19 patients admitted to the ICU were excluded, incidence of thrombosis was similar in males regardless of positive/non-positive SARS-CoV-2 status. In the full year of follow-up, increased incidence of heart failure and of arrhythmias and thrombosis was observed in SARS-CoV-2 positive females and males, respectively.

BackgroundBariatric surgery (BS) is the most effective intervention for severe obesity, leading to sustained weight loss, reduced obesity-related comorbidities, and cardiovascular mortality.AimTo assess changes in high-density lipoprotein (HDL) functions [cholesterol efflux capacity (CEC) and anti-inflammatory capacity] at different follow-up times in patients with severe obesity undergoing BS.MethodsA prospective observational study within a cohort of consecutively enrolled patients with severe obesity scheduled to undergo BS. In total, 62 participants (77% women), with a mean age of 42.1 years (SD 9.33 years) underwent BS. Regarding the surgical procedure, 27 (43.5%) underwent sleeve gastrectomy and 35 (56.5%) Roux-en-Y gastric bypass. All patients were evaluated preoperatively and at 1, 3, 6, and 12 months after surgery.ResultsA decrease in body mass index and an improvement in the systemic lipid profile, indicated by reductions in total cholesterol, low-density lipoprotein cholesterol (LDLc), and remnant cholesterol, and an increase in HDL cholesterol (HDLc) was observed (all p trend

Abstract The emergence of new structures can often be linked to the evolution of novel cell types that follows the rewiring of developmental gene regulatory subnetworks. Vertebrates are characterized by a complex body plan compared to the other chordate clades and the question remains of whether and how the emergence of vertebrate morphological innovations can be related to the appearance of new embryonic cell populations. We previously proposed, by studying mesoderm development in the cephalochordate amphioxus, a scenario for the evolution of the vertebrate head mesoderm. To further test this scenario at the cell population level, we used scRNA-seq to construct a cell atlas of the amphioxus neurula, stage at which the main mesodermal compartments are specified. Our data allowed us to validate the presence of a prechordal-plate like territory in amphioxus. Additionally, the transcriptomic profile of somite cell populations supports the homology between specific territories of amphioxus somites and vertebrate cranial/pharyngeal and lateral plate mesoderm. Finally, our work provides evidence that the appearance of the specific mesodermal structures of the vertebrate head was associated to both segregation of pre-existing cell populations, and co-option of new genes for the control of myogenesis.

Frontotemporal Dementia (FTD) encompasses a diverse group of progressive neurodegenerative diseases that impact speech production and comprehension, higher-order cognition, behavior, and motor control. Traditional acoustic speech markers have been extensively studied in FTD, as have assessments capturing apathy and impairments in recognizing and expressing emotion. This work leverages machine learning to track changes in emotional content within the speech of individuals with FTD and healthy controls. The aim of the project is to develop tools for assessing and monitoring emotional changes in individuals with FTD, quantifying these subtle aspects of the disease and thus potentially providing insights for assessing future therapeutic interventions. A retrospective analysis was conducted on a dataset comprising standard elicited speech tasks performed by 78 individuals diagnosed with FTD and 55 healthy elderly controls. We employed an ensemble-based convolutional neural network (CNN) classifier trained on the Interactive Emotional Dyadic Motion Capture (IEMOCAP) dataset to extract emotion scores from processed speech samples. The classifier was applied with a sliding window to the FTD and healthy control narratives to facilitate a granular examination of emotional changes throughout longer speech samples. Analysis of variance (ANOVA) was used to test for group differences in average emotion scores as well as emotional variability over the duration of the speech samples. Compared to healthy controls, people with FTD demonstrated reduced emotional change in a monologue task describing a happy experience, as measured by the interquartile range (IQR) (p ¡ 0.005) and slope of “happy” emotion scores vs. time (p ¡ 0.005). During a picture description task, people with FTD displayed a slightly elevated average level of frustration (p ¡ 0.005). Increased frustration levels in individuals with FTD could potentially indicate their difficulties in accomplishing the task. This study introduced the application of a pre-trained Speech Emotion Recognition (SER) model on overlapping short segments of extended speech samples, allowing for a detailed examination of emotional changes over time. Capturing the temporal evolution of emotional content offers a nuanced understanding of communication in individuals with FTD. Our findings lay the groundwork for further development of digital biomarkers to refine the assessment, monitoring, and understanding of the emotional and social communication impacts of FTD.

This project aims to establish the acceptability and satiety of a hybrid snack containing plant protein and a small percentage of animal protein compared to a meat-based snack. Design: Randomised, crossover, double-blind, controlled post-prandial trial involving 24 participants (18–30 years), with two interventions: (a) a hybrid snack containing plant protein derived from chickpeas and 6.6% lean high-quality pork meat; and (b) a meat-based snack containing 90% lean pork meat. Methods: General, life-style, sensory acceptability questionnaire, and the following laboratory analyses were performed: lipid profile, endocannabinoids, and related compounds. Results: Sensory questionnaires showed in general good acceptability for both bars. Additionally, there was a greater increase in glycemia at 30, 60, and 90 min after consuming the hybrid snack compared to the meat-based snack, with no changes in the lipid profile. Regarding the endocannabinoid compounds and related compounds, the compound N-palmitoleoyl ethanolamine in the acylethanolamide group showed higher levels overall following the consumption of the hybrid snack compared to the meat-based snack, particularly at 2 h. Conclusions: The hybrid snack was associated with changes in endocannabinoid-like compounds. Therefore, it may provide a lasting satiating effect, while complementing the protein profile of plant-based foods with the quality of animal protein.

Abstract Mercury (Hg) pollution in agricultural soils and its potential pathway to the human food chain can pose a serious health concern. Understanding the pathway of Hg in plants and how the speciation may change upon interaction with other elements used for biofortification can be critical to assess the real implications for the final plant-based product. In that respect, selenium (Se) biofortification of crops grown in Se-poor soil regions is becoming a common practice to overcome Se deficient diets. Therefore, it is important to assess the interplay between these two elements since Se may form complexes with Hg reducing its bioavailability and toxicity. In this work, the speciation of Hg in wheat plants grown hydroponically under the presence of Hg (HgCl2) and biofortified with Se (selenite, selenate, or a 1:1 mixture of both) has been investigated by X-ray absorption spectroscopy at the Hg L3-edge. The main Hg species found in wheat grains was the highly toxic methylmercury. It was found that the Se-biofortification of wheat did not prevent, in general, the Hg translocation to grains. Only the 1:1 mixture treatment seemed to have an effect in reducing the levels of Hg and the presence of methylmercury in grains.

Influenza vaccination is the main method of preventing influenza. Vaccination is recommended for certain individuals with diseases that could cause complications in the case of flu infection. The objective of this retrospective observational study was to examine influenza vaccination coverage in patients with risk factors, to describe the characteristics of those vaccinated and to study the influence of COVID-19. The study population was children under 14 years old with risk factors between 2018/19 and 2022/23 in Central Catalonia, sourced through the electronic database of the Catalan Institute of Health. The association of influenza vaccination data with sociodemographic data and risk factors was performed by bivariate and multivariate analysis. A total of 13,137 children were studied. Of those, 4623 had received the influenza vaccine in at least one season. The average influenza vaccination rate was 28.8%. The statistically significant factors associated with vaccination were age and having certain risk factors: asthma, diabetes, haemoglobinopathies and clotting disorders. In all seasons, the immigrant population was vaccinated more than the native population p < 0.05, except for the COVID-19 season (2020/21), where no differences were observed. Of those vaccinated, 7.1% had been vaccinated for 5 consecutive years. Influenza vaccination coverage in the paediatric age group was low. Vaccination promotion measures must be implemented. COVID-19 meant an increase in vaccination of the native population to the same level as that of the immigrant population.

Resumen Objetivo: Evaluar el impacto del uso de la investigación-acción participativa como método de investigación en la mejora del manejo del dolor de las personas mayores con demencia atendidos en una unidad de geriatría de agudos. Metodología: Estudio descriptivo-interpretativo enmarcado en las fases 3 y 4 de una investigación-acción participativa según el modelo propuesto por Kemmis y McTaggart. Las participantes fueron las enfermeras de la unidad de geriatría de agudos que habían participado en las 2 fases anteriores. Para la recolección de datos se usó un cuestionario con preguntas cerradas y preguntas abiertas. Para los datos cuantitativos se utilizó un análisis descriptivo y para los cualitativos, análisis del contenido. Resultados: El programa formativo, como intervención investigación-acción participativa, mejoró el conocimiento de las enfermeras. Este aprendizaje podría contribuir a modificar su práctica y a mejorar los resultados en los pacientes. Además, las enfermeras manifestaron que el programa les motivó a reflexionar sobre su práctica tanto a nivel individual como colectivo y les ha hecho tomar conciencia de la importancia que tiene un óptimo manejo del dolor en los mayores con demencia. El hecho de participar en las reuniones y discutir con sus compañeras sobre su práctica contribuyó a aprender nuevas formas de llevar a cabo acciones en relación con el manejo del dolor y promocionó el trabajo en equipo. Conclusiones: Un proceso de investigación-acción participativa puede ser una buena metodología para introducir y mantener cambios en la práctica enfermera para la mejora del manejo del dolor en personas mayores con demencia.

RESUMEN El objetivo de este estudio es describir la incidencia de bullying LGBTfóbico y analizar los factores que pueden influir en el clima escolar entre los adolescentes LGBT+. Un total de 164 adolescentes LGBT+ de 12 a 18 años respondieron una encuesta centrada en conocer sus percepciones sobre el bullying LGBTfóbico. El análisis evidenció que existen factores de protección que favorecen la disminución de la incidencia de bullying LGBTfóbico. Pese a ello, parte de la muestra ha reportado acoso escolar, lo que indica a la necesidad de análisis de dichas acciones. Se considera urgente que los centros educativos velen por la seguridad del alumnado. Ese contexto puede ser uno de los mejores canales de intervención para provocar el cambio social positivo hacia la igualdad.

The aim is to analyse that, during the current pandemic situation, the reduction in the number of cases of influenza suggests that the non-pharmaceutical interventions (NPIs) applied to contain the expansion of SARS-CoV-2 also affect the influenza expansion. We analyse the interaction of influenza and SARS-CoV-2 spread based on an extended SEIRD model for the Catalonia region in Spain. We show that the dynamic evolution of the spread of SARS-CoV-2 and influenza generates a small interference. This interference causes a small reduction in the number of cases of seasonal influenza, reducing its expansion over the population. Other elements like the face mask mandates, social distancing and hand cleaning boost the reduction in both expansions. Influenza expansion will present a small reduction in the number of cases due to the interaction with SARS-CoV-2 expansion but mainly because the NPIs applied to the population.
