A task force for diagnosis and treatment of people with Alzheimer’s disease in Latin America

Alzheimer’s disease (AD) represents a substantial burden to patients, their caregivers, health systems, and society in Latin America and the Caribbean (LAC). This impact is exacerbated by limited access to diagnosis, specialized care, and therapies for AD within and among nations. The region has varied geographic, ethnic, cultural, and economic conditions, which create unique challenges to AD diagnosis and management. To address these issues, the Americas Health Foundation convened a panel of eight neurologists, geriatricians, and psychiatrists from Argentina, Brazil, Colombia, Ecuador, Guatemala, Mexico, and Peru who are experts in AD for a three-day virtual meeting to discuss best practices for AD diagnosis and treatment in LAC and create a manuscript offering recommendations to address identified barriers. In LAC, several barriers hamper diagnosing and treating people with dementia. These barriers include access to healthcare, fragmented healthcare systems, limited research funding, unstandardized diagnosis and treatment, genetic heterogeneity, and varying social determinants of health. Additional training for physicians and other healthcare workers at the primary care level, region-specific or adequately adapted cognitive tests, increased public healthcare insurance coverage of testing and treatment, and dedicated search strategies to detect populations with gene variants associated with AD are among the recommendations to improve the landscape of AD

Search for 22^{22}Na in novae supported by a novel method for measuring femtosecond nuclear lifetimes

Classical novae are thermonuclear explosions in stellar binary systems, and important sources of $^{26}$Al and $^{22}$Na. While gamma rays from the decay of the former radioisotope have been observed throughout the Galaxy, $^{22}$Na remains untraceable. The half-life of $^{22}$Na (2.6 yr) would allow the observation of its 1.275 MeV gamma-ray line from a cosmic source. However, the prediction of such an observation requires good knowledge of the nuclear reactions involved in the production and destruction of this nucleus. The $^{22}$Na($p,\gamma$)$^{23}$Mg reaction remains the only source of large uncertainty about the amount of $^{22}$Na ejected. Its rate is dominated by a single resonance on the short-lived state at 7785.0(7) keV in $^{23}$Mg. In the present work, a combined analysis of particle-particle correlations and velocity-difference profiles is proposed to measure femtosecond nuclear lifetimes. The application of this novel method to the study of the $^{23}$Mg states, combining magnetic and highly-segmented tracking gamma-ray spectrometers, places strong limits on the amount of $^{22}$Na produced in novae, explains its non-observation to date in gamma rays (flux < 2.5x$10^{-4}$ ph/(cm$^2$s)), and constrains its detectability with future space-borne observatories.Comment: 18 pages, 3 figures, 1 tabl

Desarrollo educativo al servicio del desarrollo social

La publicación recoge las aportaciones y los trabajos realizados con motivo del "Proyecto de apoyo y fortalecimiento educacional en gestión directiva y competencias profesionales docentes", promovido por varias instituciones, coordinado por el Equipo de Desarrollo Organizacional (EDO) de la Universidad Autónoma de Barcelona; y subvencionado por la Agencia Española de Cooperación Internacional para el Desarrollo (AECID). La finalidad del proyecto, en el que se enmarcan las aportaciones de la publicación, es construir una red de cooperación y apoyo con y entre los centros educativos dependientes de la municipalidad de Coyhaique (Chile), para impulsar la mejora educativa y con ella el desarrollo social y cultural del territorio. La temática enlaza con la labor promotora del desarrollo y el liderazgo que las universidades han de realizar en su contexto referencial; además, de potenciar el rol y el compromiso del profesorado en esos procesos. Durante los dos años y medio transcurridos en la materialización del proyecto, la labor realizada en 12 escuelas dependientes del Departamento de Educación de la municipalidad de Coyhaique ha sido intensa por la cantidad de acciones y actividades desarrolladas, fructífera en relación al proceso de desarrollo de colaboración interuniversitaria de la Universidad de Talca y la Universidad Autónoma de Barcelona y muy satisfactoria en relación a los procesos iniciados y a los indicadores de éxito ya alcanzados. La aportación recoge reflexiones sobre la temática y realizaciones de los doce centros. La proyección última es la de mejorar la capacidad de los centros para promover los cambios que posibiliten aumentar su calidad educativa e, indirectamente, mejorar el desarrollo social a partir de una mejor cualificación de sus recursos humanos y de una mayor implicación social de los promotores del mismo

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Brucella ceti infection in dolphins from the Western Mediterranean sea

Background: Brucella ceti infections have been increasingly reported in cetaceans. Brucellosis in these animals is associated with meningoencephalitis, abortion, discospondylitis', subcutaneous abscesses, endometritis and other pathological conditions B. ceti infections have been frequently described in dolphins from both, the Atlantic and Pacific Oceans. In the Mediterranean Sea, only two reports have been made: one from the Italian Tyrrhenian Sea and the other from the Adriatic Sea.Results: We describe the clinical and pathological features of three cases of B. ceti infections in three dolphins stranded in the Mediterranean Catalonian coast. One striped dolphin had neurobrucellosis, showing lethargy, incoordination and lateral swimming due to meningoencephalitis, A B. ceti infected bottlenose dolphin had discospondylitis, and another striped dolphin did not show clinical signs or lesions related to Brucella infection. A detailed characterization of the three B. ceti isolates was performed by bacteriological, molecular, protein and fatty acid analyses.Conclusions: All the B. ceti strains originating from Mediterranean dolphins cluster together in a distinct phylogenetic clade, close to that formed by B. ceti isolates from dolphins inhabiting the Atlantic Ocean. Our study confirms the severity of pathological signs in stranded dolphins and the relevance of B. ceti as a pathogen in the Mediterranean Sea.Antecedentes: Las infecciones por Brucella ceti se han notificado cada vez más en los cetáceos. La brucelosis en estos animales se asocia con meningoencefalitis, aborto, discopondilitis, abscesos subcutáneos, endometritis y otras condiciones patológicas. Las infecciones por B. ceti se han descrito con frecuencia en delfines de los océanos Atlántico y Pacífico. En el Mar Mediterráneo, sólo se han hecho dos informes: uno del Mar Tirreno italiano y el otro del Mar Adriático: Describimos las características clínicas y patológicas de tres casos de infecciones de B. ceti en tres delfines varados en la costa mediterránea catalana. Un delfín listado presentaba neurobrucelosis, mostrando letargo, incoordinación y natación lateral debido a la meningoencefalitis, el delfín mular infectado por B. ceti presentaba discopondilitis, y otro delfín listado no mostraba signos clínicos o lesiones relacionadas con la infección por Brucella. Se realizó una caracterización detallada de los tres aislamientos de B. ceti mediante análisis bacteriológicos, moleculares, de proteínas y de ácidos grasos. Conclusiones: Todas las cepas de B. ceti procedentes de delfines del Mediterráneo se agrupan en un clado filogenético distinto, cercano al formado por los aislamientos de B. ceti de los delfines que habitan en el Océano Atlántico. Nuestro estudio confirma la gravedad de los signos patológicos en los delfines varados y la relevancia de B. ceti como patógeno en el Mar Mediterráneo.Universidad Nacional, Costa RicaEscuela de Medicina Veterinari

Search for 22Na in novae supported by a novel method for measuring femtosecond nuclear lifetimes

Abstract Classical novae are thermonuclear explosions in stellar binary systems, and important sources of 26Al and 22Na. While γ rays from the decay of the former radioisotope have been observed throughout the Galaxy, 22Na remains untraceable. Its half-life (2.6 yr) would allow the observation of its 1.275 MeV γ-ray line from a cosmic source. However, the prediction of such an observation requires good knowledge of its nucleosynthesis. The 22Na(p, γ)23Mg reaction remains the only source of large uncertainty about the amount of 22Na ejected. Its rate is dominated by a single resonance on the short-lived state at 7785.0(7) keV in 23Mg. Here, we propose a combined analysis of particle-particle correlations and velocity-difference profiles to measure femtosecond nuclear lifetimes. The application of this method to the study of the 23Mg states, places strong limits on the amount of 22Na produced in novae and constrains its detectability with future space-borne observatories
