Objetive: to correlate the main variable of primary income earner or primary breadwinner with gender, age, working hours, sleep hours, and cardiovascular disease risk factors (body mass index, hypertension, dyslipidemia, and diabetes mellitus) in 3rd, 4th, and 5th-year nursing students at the Nursing Program at the National University of Formosa. Methodology: The study was a descriptive, correlational, cross-sectional, conducted with 214 students during 2022 using a self-administered structured online questionnaire and measurement of weight and height. Results: 76% were women, 64% were the main breadwinner, 57% reported sleeping less than 6 hours a day, 15% working more than 41 hours per week; 67% had unhealthy responses to the stress variable, this value rose to 71% for the physical activity variable, and 53.8% were overweight. A significant association was found between the main variable of primary breadwinner and being overweight, working 41 or more hours weekly, and the presence of 3 or more cardiovascular risk factors. Conclusions: The living conditions faced by students who simultaneously study and work, and being the main breadwinner in the household can generate stress, which is a risk factor for cardiovascular diseases[AU]

Slow recovery rates and spatial aggregation of Triatoma infestans populations in an area with high pyrethroid resistance in the Argentine Chaco.

BACKGROUND: The emergence of pyrethroid resistance has threatened the elimination of Triatoma infestans from the Gran Chaco ecoregion. We investigated the status and spatial distribution of house infestation with T. infestans and its main determinants in Castelli, a municipality of the Argentine Chaco with record levels of triatomine pyrethroid resistance, persistent infestation over 2005-2014, and limited or no control actions over 2015-2020. METHODS: We conducted a 2-year longitudinal survey to assess triatomine infestation by timed manual searches in a well-defined rural section of Castelli including 14 villages and 234 inhabited houses in 2018 (baseline) and 2020, collected housing and sociodemographic data by on-site inspection and a tailored questionnaire, and synthetized these data into three indices generated by multiple correspondence analysis. RESULTS: The overall prevalence of house infestation in 2018 (33.8%) and 2020 (31.6%) virtually matched the historical estimates for the period 2005-2014 (33.7%) under recurrent pyrethroid sprays. While mean peridomestic infestation remained the same (26.4-26.7%) between 2018 and 2020, domestic infestation slightly decreased from 12.2 to 8.3%. Key triatomine habitats were storerooms, domiciles, kitchens, and structures occupied by chickens. Local spatial analysis showed significant aggregation of infestation and bug abundance in five villages, four of which had very high pyrethroid resistance approximately over 2010-2013, suggesting persistent infestations over space-time. House bug abundance within the hotspots consistently exceeded the estimates recorded in other villages. Multiple regression analysis revealed that the presence and relative abundance of T. infestans in domiciles were strongly and negatively associated with indices for household preventive practices (pesticide use) and housing quality. Questionnaire-derived information showed extensive use of pyrethroids associated with livestock raising and concomitant spillover treatment of dogs and (peri) domestic premises. CONCLUSIONS: Triatoma infestans populations in an area with high pyrethroid resistance showed slow recovery and propagation rates despite limited or marginal control actions over a 5-year period. Consistent with these patterns, independent experiments confirmed the lower fitness of pyrethroid-resistant triatomines in Castelli compared with susceptible conspecifics. Targeting hotspots and pyrethroid-resistant foci with appropriate house modification measures and judicious application of alternative insecticides with adequate toxicity profiles are needed to suppress resistant triatomine populations and prevent their eventual regional spread.

[Women's rescuers network: Community support for self-managed abortion in Argentina]. / Socorristas en red: Soporte comunitario a la autogestión del aborto en Argentina.

The availability of medications to induce abortion, especially in contexts of restricted access, has transformed practices and allowed women and/or their community organizations to assist other women in obtaining abortions, whether or not they interact with the healthcare system. This study recovers the experience of a feminist community organization that, from the province of Neuquén, extends throughout the country, creating a network of community care. An exploratory descriptive study with a qualitative approach was conducted to analyze the experiences of women who facilitate access to permitted abortion in Argentina. Through in-depth interviews with three leaders of the feminist collective La Revuelta and semi-structured interviews with 33 members of the socorrista groups, conducted between November 2019 and December 2020, we describe their history and processes of work and growth; we explore their motivations and feelings and characterize the interactions of these organizations with public and private health systems. The results of this work align with the international conversation and bibliographic production about these organizations and their particularities, and with the need to incorporate these forms of care into institutional health systems.

La disponibilidad de medicamentos para producir un aborto, sobre todo en contextos de acceso restringido, transformó las prácticas y permitió que las propias mujeres y/o sus organizaciones comunitarias ayuden a otras mujeres a abortar, interactuando o no con el sistema de salud. Este estudio recupera la experiencia de una organización feminista de la comunidad que, desde la provincia de Neuquén, se extiende a todo el país, generando una red de cuidados comunitarios. Se realizó un estudio exploratorio descriptivo, con enfoque cualitativo con el propósito de analizar las experiencias de las mujeres que facilitan el acceso al aborto permitido en Argentina. A través de entrevistas en profundidad a tres líderes de la colectiva feminista La Revuelta y de entrevistas semiestructuradas a 33 integrantes de las grupas socorristas, realizadas entre noviembre de 2019 y diciembre de 2020, describimos su historia y los procesos de trabajo y crecimiento; exploramos sus motivaciones y sentimientos y caracterizamos las interacciones de dichas organizaciones con los sistemas de salud público y privado. Los resultados de este trabajo coinciden con la conversación y la producción bibliográfica internacional acerca de estas organizaciones y sus particularidades y con la necesidad de incorporar estos cuidados a los sistemas de salud institucionales.

A Survey of Availability and Affordability of Polypills for Cardiovascular Disease in Selected Countries.

Background: The recent inclusion of polypills-fixed-dose combinations of antihypertensive medicines and a statin with or without aspirin-in the World Health Organization's Essential Medicines List (EML) reiterates the potential of this approach to improve global treatment coverage for cardiovascular diseases (CVDs). Although there exists extensive evidence on the effectiveness, safety and acceptability of polypills, there has been no research to date assessing the real-world availability and affordability of polypills globally. Methods: We conducted a cross-sectional survey, based on the WHO/Health Action International methodology, in 13 countries around the world. In the surveyed countries, we first ascertained whether any polypill was authorised for marketing and/or included in EMLs and clinical guidelines. In each country, we collected retail and price data for polypills from at least one public-sector facility and three private pharmacies using convenience sampling. Polypills were considered unaffordable if the lowest-paid worker spent more than a day's wage to purchase a monthly supply. Results: Polypills were approved for marketing in four of the 13 surveyed countries: Spain, India, Mauritius and Argentina. None of these countries included polypills in national guidelines, formularies, or EMLs. In the four countries, no surveyed public pharmacies stocked polypills. In the private sector, we identified seven unique polypill combinations, marketed by eight different companies. Private sector availability was 100% in Argentina and Spain. Most combinations (n = 5) identified were in India. Combinations found in India and Spain were affordable in the local context. A lowest-paid government worker would spend between 0.2 (India) and 2.8 (Mauritius) days' wages to pay the price for one month's supply of the polypills. Polypills were likely to be affordable if they were manufactured in the same country. Conclusion: Low availability and affordability of polypills in the public sector suggest that implementation remains poor globally. Context-specific multi-disciplinary health system research is required to understand factors affecting polypill implementation and to design and evaluate appropriate implementation strategies.

[The life path of Irma Carrica: An approach to the political and health debates of the 1960s and 1970s using the biographical method]. / La trayectoria de vida de Irma Carrica: una aproximación a los debates político-sanitarios de las décadas de 1960 y 1970 desde el método biográfico.

We reconstruct the life path of the Argentine nurse and popular activist Irma Carrica, understood as a political-professional experience tied to her social networks and marked by conflicts and contradictions inherent to her historical context. From this analytical perspective and considering the precautions suggested by the biographical method of social sciences, we delve into the political and health debates of the 1960s and 1970s, particularly concerning disputes over the meaning of "community" in the health field. Specifically, we focus on the contributions of a collective historical actor - heterogeneous and plural, yet identifiable in its various forms - that we have termed the Peronist Left in health. By analyzing their professional and intellectual networks, we emphasize the role played by Irma Carrica as a representative of this Peronist Left in health, in constructing alternative dynamics for community health approaches, which challenged the dominant epistemological and pedagogical paradigms.

Reconstruimos la trayectoria de vida de la enfermera y militante popular argentina Irma Carrica, entendida como una experiencia político-profesional ligada a sus redes de sociabilidad y atravesada por conflictos y contradicciones inherentes a su contexto histórico. Desde ese recorte analítico y teniendo en cuenta los recaudos sugeridos por el método biográfico de las ciencias sociales, nos adentramos en los debates político-sanitarios de las décadas de 1960 y 1970, principalmente en lo relativo a las disputas por el sentido de la "comunidad" en el campo de la salud. En particular, nos enfocamos en las contribuciones de un actor histórico colectivo ­heterogéneo y plural, pero identificable en sus distintas modulaciones­ que hemos denominado izquierda peronista en salud. Al analizar sus redes profesionales e intelectuales, hicimos hincapié en el rol que desempeñó Irma Carrica como referente de esa izquierda peronista en salud, a la hora de construir dinámicas alternativas para el abordaje comunitario en salud, que pusieron en tela de juicio los paradigmas epistemológicos y pedagógicos dominantes.

Gastrointestinal parasites of Wolffsohn's viscacha (Chinchillidae: Lagidium wolffsohni), an endemic rodent species from the wild Patagonia.

Parasites are ubiquitous in wildlife populations and have a profound impact on population dynamics. Interest in parasites of wildlife has increased significantly in recent years, particularly in those with relevant conservation status. Patagonia is one of the wildest and remote areas of the world. The Wolffsohn's viscacha lives in a small mountainous area of Patagonia. Until now, little is known about the biology and ecology of this species. The aim of this research was to study the gastrointestinal parasite diversity in this rodent from a coprological survey. A total of 125 fecal samples from 25 colonies were examined. Each sample was rehydrated, homogenized, and analyzed using three parasitological techniques: spontaneous sedimentation, Mini-FLOTAC, and centrifugation-flotation in sucrose-saturated solution, followed by examination under optical microscopy. The samples, eggs, and oocysts of parasites were described, measured, and photographed. All colonies were positive for at least one parasite species. A total of 10 parasitic species were identified: Viscachataenia sp., possibly V. quadrata, Monoecocestus sp., an unidentified anoplocephalid, Heteroxynema sp., possibly H. (Cavioxyura) viscaciae, Helminthoxys sp., possibly H. effilatus, an unidentified strongylid-type egg, Trichuris sp., two morphologies of unidentified coccidians and Eimeria sp. This is the first exhaustive study of gastrointestinal parasites in L. wolffsohni and a large number of eggs and oocysts of parasites were found. Our results highlight the use of noninvasive techniques for the study of parasites of wildlife hosts; as in the case of this rodent with a remote habitat, which makes sampling difficult. The results of our study provide baseline information on gastrointestinal parasite infections in this species.

Unraveling sauropod diversity in the Portezuelo Formation of Patagonia through a comprehensive analysis of new and existing material.

The Portezuelo Formation preserves an outstanding record of the upper Turonian - lower Coniacian. Despite the discovery of a significant quantity of sauropod fossil material from the formation, only two species have been formally described to date: Malarguesaurus florenciae and Futalognkosaurus dukei. Here we present new sauropod material mostly composed of non-articulated caudal vertebrae (MCF-PVPH 916 and 917) that belong to two titanosauriforms on the basis of the following features: anterior caudal vertebrae with procoelous-opisthoplatyan articulations, transverse processes that reach the posterior articular face of the centrum and neural spines with a transverse width of around 50% of their anteroposterior length; anterior and middle caudal vertebrae with the neural arch restricted to the anterior half of the centrum; middle caudal centra with circular cross-section. Phylogenetic analysis recovers the new material in close relation to Malarguesaurus within a monophyletic clade at the base of Somphospondyli. This clade shares large pedicel height with a vertical anterior border on the middle caudal vertebrae, a vertical orientation of the neural spines on the distalmost middle caudal vertebrae and proximalmost posterior caudal vertebrae, and subequal relative lengths of the proximal ulnar condylar processes. The specimens presented here are distinct not only from Futalognkosaurus, but also from other indeterminate titanosaurian remains from the same formation. However, there are no significant differences between the specimen MCF-PVPH 917 and Malarguesaurus, but there are differences between the posterior caudal vertebrae of MCF-PVPH 916 and Malarguesaurus, so they could be considered different species. Whilst we err on the side of caution in not naming new taxa here, the two specimens significantly expand what we know about sauropods in the Turonian-Coniacian ecosystems of Patagonia, which will continue to do so as more material is discovered.

Southern marsh deer (Blastocerus dichotomus) populations assessed using Amplicon Sequencing on fecal samples.

Populations in isolated and small fragments lose genetic variability very fast and are usually of conservation concern because they are at greater risk of local extinction. The largest native deer in South America, Blastocerus dichotomus (Illiger, 1815), is a Vulnerable species according to the IUCN categorization, which inhabits tropical and subtropical swampy areas. In Argentina, its presence has been restricted to four isolated fragments. Here we examine the genetic diversity and differentiation among three of them, including the three different patches that form the southernmost population, using 18 microsatellite markers genotyped by Amplicon Sequencing of DNA extracted from fecal samples. Genetic diversity was low (HE < 0.45) in all three populations studied. We found three genetic clusters compatible with the geographic location of the samples. We also found a metapopulation dynamics that involves the patches that make up the southernmost population, with evidence of a barrier to gene flow between two of them. Our results point to the creation of a corridor as a necessary and urgent management action. This is the first study, at the population level, employing microsatellite genotyping by Amplicon Sequencing with non-invasive samples in an endangered species.

Detection and characterization of Deformed Wing Virus (DWV) in apiaries with stationary and migratory management in the province of Entre Ríos, Argentina.

In Argentina, migratory activity in search of floral diversity has become a common approach to maximizing honey production. The Entre Ríos province possesses a floral diversity that allows beekeepers to perform migratory or stationary management. Beyond the impact caused by transhumance, migratory colonies in this province start and end the season in monoculture areas. To study the effect of these practices on viral infection, we assayed for the presence, abundance and genetic characterization of the Deformed Wing Virus (DWV) in honey bees from apiaries with both types of management. In migratory apiaries, DWV was detectable in 86.2% of the colonies at the beginning of the season (September 2018), and 66% at the end of the season (March 2019). On the other hand, DWV was detected in 44.11% and 53.12% of stationary samples, at the beginning and the end of the season, respectively. Sequence analysis from migratory and stationary colonies revealed that all samples belonged to DWV-A type. The highest viral loads were detected in migratory samples collected in September. Higher DWV presence and abundance were associated with migratory management and the sampling time. Based on our findings we propose that the benefit of migration to wild flowering areas can be dissipated when the bee colonies end the season with monoculture.

Anthropic cut marks in extinct megafauna bones from the Pampean region (Argentina) at the last glacial maximum.

The initial peopling of South America is a topic of intense archaeological debate. Among the most contentious issues remain the nature of the human-megafauna interaction and the possible role of humans, along with climatic change, in the extinction of several megamammal genera at the end of the Pleistocene. In this study, we present the analysis of fossil remains with cutmarks belonging to a specimen of Neosclerocalyptus (Xenarthra, Glyptodontidae), found on the banks of the Reconquista River, northeast of the Pampean region (Argentina), whose AMS 14C dating corresponds to the Last Glacial Maximum (21,090-20,811 cal YBP). Paleoenvironmental reconstructions, stratigraphic descriptions, absolute chronological dating of bone materials, and deposits suggest a relatively rapid burial event of the bone assemblage in a semi-dry climate during a wet season. Quantitative and qualitative analyses of the cut marks, reconstruction of butchering sequences, and assessments of the possible agents involved in the observed bone surface modifications indicate anthropic activities. Our results provide new elements for discussing the earliest peopling of southern South America and specifically for the interaction between humans and local megafauna in the Pampean region during the Last Glacial Maximum.

Development and Implementation of a Safety Incident Report System for Health Care Discipline Students During Clinical Internships: Observational Study.

BACKGROUND: Patient safety is a fundamental aspect of health care practice across global health systems. Safe practices, which include incident reporting systems, have proven valuable in preventing the recurrence of safety incidents. However, the accessibility of this tool for health care discipline students is not consistent, limiting their acquisition of competencies. In addition, there is no tools to familiarize students with analyzing safety incidents. Gamification has emerged as an effective strategy in health care education. OBJECTIVE: This study aims to develop an incident reporting system tailored to the specific needs of health care discipline students, named Safety Incident Report System for Students. Secondary objectives included studying the performance of different groups of students in the use of the platform and training them on the correct procedures for reporting. METHODS: This was an observational study carried out in 3 phases. Phase 1 consisted of the development of the web-based platform and the incident registration form. For this purpose, systems already developed and in use in Spain were taken as a basis. During phase 2, a total of 223 students in medicine and nursing with clinical internships from universities in Argentina, Brazil, Colombia, Ecuador, and Spain received an introductory seminar and were given access to the platform. Phase 3 ran in parallel and involved evaluation and feedback of the reports received as well as the opportunity to submit the students' opinion on the process. Descriptive statistics were obtained to gain information about the incidents, and mean comparisons by groups were performed to analyze the scores obtained. RESULTS: The final form was divided into 9 sections and consisted of 48 questions that allowed for introducing data about the incident, its causes, and proposals for an improvement plan. The platform included a personal dashboard displaying submitted reports, average scores, progression, and score rankings. A total of 105 students participated, submitting 147 reports. Incidents were mainly reported in the hospital setting, with complications of care (87/346, 25.1%) and effects of medication or medical products (82/346, 23.7%) being predominant. The most repeated causes were related confusion, oversight, or distractions (49/147, 33.3%) and absence of process verification (44/147, 29.9%). Statistically significant differences were observed between the mean final scores received by country (P<.001) and sex (P=.006) but not by studies (P=.47). Overall, participants rated the experience of using the Safety Incident Report System for Students positively. CONCLUSIONS: This study presents an initial adaptation of reporting systems to suit the needs of students, introducing a guided and inspiring framework that has garnered positive acceptance among students. Through this endeavor, a pathway toward a safety culture within the faculty is established. A long-term follow-up would be desirable to check the real benefits of using the tool during education.

Diagnosis of Chagas Disease by Detecting Species-Specific Repetitive Genomic DNA from Filtered Human Urine Samples.

INTRODUCTION: Chagas disease caused by Trypanosoma cruzi (T cruzi) found in the Americas is often missed during the early stage of infection due to lack of sensitive diagnostic tests. The classic immunological and parasitological tests often fail in the acute phase due to the nonspecific and low antibody level nature of the infection and in the chronic phase due to low levels of trypanosomes in the blood. For successful control strategies, there must be a sensitive and specific diagnostic test. OBJECTIVE/METHODS: We have demonstrated the possibility (proof of concept) of detecting T cruzi-specific repeat DNA via polymerase chain reaction (PCR) by (1) spiking 15 urine samples collected from volunteers free of prior infection with 3 different concentrations of T cruzi (3 strains), Trypanosoma brucei, and Trypanosoma rhodesiense (African strain) genomic DNA and (2) from filtered collected clinical samples from Argentina. Three sets of primers were used. RESULTS: Our approach detected repeat DNA specific for T cruzi strains from 1 clinical sample by 2 sets of primer and from spiked urine by all 3 sets of primer but not the African species. A serial dilution (spiking) also was performed on T cruzi strains to detect sensitivities of the assay. One set of primers constantly detected satellite DNA for all T cruzi strains from 70 pg/µl to 175 fg/µl. CONCLUSIONS: We were able to demonstrate the feasibility of detecting T cruzi-specific DNA from filtered urine samples by sensitive and specific PCR assay. Besides the evident increased sensitivity and specificity of primers, our approach can be used to explore Chagas prevalence in endemic areas - especially in congenital Chagas newborn screening - and in the acute phase.

Reinternaciones psiquiátricas: Determinantes clínicos, sociales ydemográficos en un hospital de la Ciudad de Buenos Aires.

OBJETIVO: Este trabajo busca determinar las variables asociadas a las rehospitalizaciones múltiples en una sala de internación de mujeres, del Hospital de Emergencias Psiquiátricas "Torcuato de Alvear" de la Ciudad de Buenos Aires, Argentina. Método: El presente es un estudio analítico, de tipo transversal, en el que se incluyeron consecutivamente 350 pacientes de entre 18 y 65 años, hospitalizadas desde 2013 hasta diciembre de 2017 en la sala de internación de mujeres de dicho hospital. Al momento del alta se recabaron datos sociodemográficos, clínicos y sobre las condiciones de externación de todas las pacientes. Se definió internaciones múltiples al haber tenido 3 o más internaciones previas al momento de la actual internación. Para variables continuas se realizó test t o el análisis de varianza (ANOVA) en casos de distribución normal, y test de Mann- Whitney y Kruskal-Wallis en casos de distribución asimétrica. Las variables cualitativas se analizaron a través del test de chi-cuadrado con corrección de continuidad. La asociación entre variables se evaluó a través de los coeficientes de correlación de Pearson o Spearman según corresponda. RESULTADOS: Las variables asociadas con reinternaciones múltiples fueron: el diagnóstico de Trastorno Bipolar, encontrarse realizando tratamiento al ingreso, así como la precariedad habitacional, la falta de trabajo y de autonomía económica. Conclusión: Las variables representativas de vulnerabilidad social y económica se asociaron con la utilización de camas de  internación psiquiátrica. Son necesarias políticas públicas que permitan interrumpir la relación entre pobreza y patología mental.

Estudio binacional sobre las agresiones de pareja en estudiantes universitarios.

En esta investigación se dimensiona comparativamente la violencia en parejas de estudiantes de nivel universitario de la Argentina y de Ecuador y se explora la asociación con los celos y otras covariables teóricamente relevantes mediante análisis multivariado. Con un diseño de corte transversal se encuestaron 714 estudiantes (528 de la Universidad Nacional de La Plata, Argentina, y 186 de Universidad de Cuenca, Ecuador). Los instrumentos utilizados fueron el Conflict in Adolescents Dating Relationships Inventory, la Multidimensional Jealousy Scale e items ad hoc sobre fidelidad, consumo de sustancias y estrés durante la relación de pareja. Si bien se halló un predominio de la violencia verbal/emocional, el 3,8 % de los participantes alcanzó alto valor en la medida de abuso total cometido y más de la mitad informó haber cometido, por lo menos, un acto violento físico durante la relación índice. En modelo de regresión logística se verificó que la condición de pertenecer al grupo de alta violencia se asoció positiva y significativamente con los factores celos comportamentales, celos cognitivos,estrés y consumo de sustancias, y negativa y significativamente con la edad al comienzo de la relación.

Nuevas tecnologías y atención en Salud Mental. Encuesta a psiquiatras y psicólogos de Argentina sobre el uso del WhatsApp.

OBJETIVOS: La comunicación entre pacientes y profesionales de la salud mental mediante plataformas de mensa- jería en el intervalo entre encuentros presenciales o virtuales se convirtió en una modalidad de teleconsulta asincrónica (TA) cuya utilidad y efecto en la carga de trabajo de los profesionales de salud mental no se han explorado. Método: Profesionales del campo de la salud mental que trabajan en Argentina fueron invitados a responder a una encuesta que exploraba la intensidad y utilidad de la TA, y la sobrecarga resultante. RESULTADOS: Se recibieron un total de 527 respuestas de profesionales que trabajan en todo el país. El 69 % de los encuestados mensajes con un promedio de 1-10 pacientes/día y el 31 % con más de 10 pacientes/día; el 75 % respondió mensajes por teléfono móvil los fines de semana. Mientras que el 68 % calificó estas interacciones como positivas para  el seguimiento clínico, el 47 % las consideró una fuente de sobrecarga laboral. CONCLUSIONES: La adopción generalizada de la TA puede requerir una autorregulación adicional por parte de los profesionales y un seguimiento regular de los niveles de sobrecarga (especialmente, entre los psiquiatras) para que su práctica clínica diaria sea eficiente y sostenible.

Guías de primeros auxilios en salud mental para Argentina y Chile: un reporte del estudio de adaptación de las guías australianas.

Introducción: Los problemas de salud mental en la comunidad representan una preocupación global creciente, intensificada desde la pandemia por coronavirus y gracias a una mayor conciencia respecto de su extensión y del bajo nivel de atención que recibieron a lo largo del tiempo. En Australia se crearon las primeras guías de primeros auxilios en salud mental para promover un mayor conocimiento de temas de salud mental en la población general, brindar apoyo oportuno, facilitar el acceso a los servicios de salud por esta problemática, y disminuir el estigma asociado al padecimiento mental. Método: Un consorcio de investigadores de Australia, Argentina y Chile, entre marzo de 2020 y mayo de 2023, realizó la adaptación cultural de cinco guías (consumo problemático de alcohol, depresión, riesgo de suicidio, trauma, y psicosis) siguiendo la metodología de consenso Delphi. Profesionales expertos en cada uno de los temas y personas con experiencia vivida  (propia o como cuidadores informales) conformaron sendos paneles con miembros de Argentina y de Chile. En dos rondas de consulta evaluaron los ítems provenientes de las guías de Australia y opinaron sobre su pertinencia para formar parte de las guías locales. Adicionalmente, sugirieron ítems que no estaban contemplados en las guías australianas. Resultados: El presente reporte presenta el detalle de la metodología empleada y los resultados más significativos de cada una de las cinco guías adaptadas y, particularmente, su aplicabilidad para Argentina y Chile. Sobresale la aceptación general del rol del asistente de primeros auxilios en salud mental, aunque también con limitaciones en el rol y funciones en favor del privilegio de profesionales de la salud. Las recomendaciones de auto-ayuda fueron mayoritariamente no aceptadas por los expertos locales, sugiriendo desconfianza respecto de estas estrategias. Otras recomendaciones específicas para cada una de las guías se describen y analizan en este reporte. Conclusiones: Se requiere un estudio de la implementación de la capacitación en base a estas guías para realizar ulteriores adaptaciones y determinar su utilidad local.

A machine of the same: Repetition in the foundational discourse of the Argentinean "being" (1976-1983).

Using the example of the military regime in Argentina (1976-1983) and relevant archival materials, this article demonstrates the prerequisite of exalted language in constructing an enemy and how a discursive 'machine of the same' was put into operation. The author argues that what made this operation unique is its structure of repetition that stimulated "the tendency to merge" what is "foreigner-to-the-ego", and the "enemy outside" into a single concept in the Argentinian national psyche.As a theoretical lens, the author examines the military regime's language through Freud's understanding of groups and civilization and Laplanche's proposition that cultural narratives in the form of mytho-symbolic explanations help us translate the sexual drive and offer a "solution" to the helplessness of the infant-adult.The author further claims that at other times a cultural narration functions as an anti-translation device when set against the emergence of a new net of significations. The nation's founding narrative of an Occidental-Spanish-Catholic "being" that first effaced its indigenous origins and then its Arabic and Jewish inheritance was brought back by the military regime as a mytho-symbolic narration that formed a shield against the repressed remnants of the enigmatic message pressing for a new translation.

Genetic characterization and estimated 4CMenB vaccine strain coverage of 284 Neisseria meningitidis isolates causing invasive meningococcal disease in Argentina in 2010-2014.

Meningococcal (Neisseria meningitidis) serogroup B (MenB) strain antigens are diverse and a limited number of strains can be evaluated using the human serum bactericidal antibody (hSBA) assay. The genetic Meningococcal Antigen Typing System (gMATS) was developed to predict the likelihood of coverage for large numbers of isolates by the 4CMenB vaccine, which includes antigens Neisseria adhesin A (NadA), Neisserial Heparin-Binding Antigen (NHBA), factor H-binding protein (fHbp), and Porin A (PorA). In this study, we characterized by whole-genome analyses 284 invasive MenB isolates collected from 2010 to 2014 by the Argentinian National Laboratories Network (52-61 isolates per year). Strain coverage was estimated by gMATS on all isolates and by hSBA assay on 74 randomly selected isolates, representative of the whole panel. The four most common clonal complexes (CCs), accounting for 81.3% of isolates, were CC-865 (75 isolates, 26.4%), CC-32 (59, 20.8%), CC-35 (59, 20.8%), and CC-41/44 (38, 13.4%). Vaccine antigen genotyping showed diversity. The most prevalent variants/peptides were fHbp variant 2, NHBA peptides 24, 21, and 2, and PorA variable region 2 profiles 16-36 and 14. The nadA gene was present in 66 (23.2%) isolates. Estimated strain coverage by hSBA assay showed 78.4% of isolates were killed by pooled adolescent sera, and 51.4% and 64.9% (based on two different thresholds) were killed by pooled infant sera. Estimated coverage by gMATS (61.3%; prediction interval: 55.5%, 66.7%) was consistent with the infant hSBA assay results. Continued genomic surveillance is needed to evaluate the persistence of major MenB CCs in Argentina.

The most common clinical manifestations of invasive meningococcal disease include meningitis and septicemia, which can be deadly, and many survivors suffer long-term serious after-effects. Most cases of invasive meningococcal disease are caused by six meningococcal serogroups (types), including serogroup B. Although vaccines are available against meningococcal serogroup B infection, these vaccines target antigens that are highly diverse. Consequently, the effectiveness of vaccination may vary from country to country because the meningococcal serogroup B strains circulating in particular regions carry different forms of the target vaccine antigens. This means it is important to test serogroup B strains isolated from specific populations to estimate the percentage of strains that a vaccine is likely to be effective against (known as 'vaccine strain coverage'). The genetic Meningococcal Antigen Typing System (gMATS) was developed to predict strain coverage by the four-component meningococcal serogroup B vaccine, 4CMenB, against large numbers of serogroup B strains. In this study, we analyzed 284 invasive meningococcal serogroup B isolates collected between 2010 and 2014 in Argentina. Genetic analyses showed that the vaccine antigens of the isolates were diverse and some genetic characteristics had not been found in isolates from other countries. However, vaccine strain coverage estimated by gMATS was consistent with that reported in other parts of the world and with strain coverage results obtained for a subset via another method, the human serum bactericidal antibody (hSBA) assay. These results highlight the need for continued monitoring of circulating bacterial strains to assess the estimated strain coverage of meningococcal serogroup B vaccines.

Habitat occupancy of the threatened Diademed Plover (Phegornis mitchellii) is not affected by llama grazing or peatland size, but declines with peatland humidity.

Many habitat-specialist organisms occur in distinct, patchy habitat, yet do not occupy all patches, and an important question is why apparently suitable habitat remains unoccupied. We examined factors influencing patch occupancy in near-threatened, little-known Diademed Plovers (Phegornis mitchellii), arguably the bird most specialized to life in High Andean peatlands. Andean peatlands are well-suited to occupancy modelling because they are discrete patches of humid habitat within a matrix of high-altitude steppe. We hypothesized that Diademed Plovers occupy preferably larger and more humid peatlands, and avoid peatlands used for grazing by llamas and vicuñas, which may trample vegetation and nests. From December 2021 to February 2022 (breeding season), we conducted plover occupancy surveys (2-4) on 40 peatlands at Lagunas de Vilama, a landscape of arid steppe and wetlands above 4,500 m in NW Argentina. We measured peatland size, grazing pressure, topographic and remotely-sensed variables that correlate with humidity, and incorporated these as covariates in occupancy models. Occupancy models showed that more than 50% of the studied peatlands were used by Diademed Plovers and most showed signs of reproduction, highlighting the importance of the Vilama Wetlands for Diademed Plover conservation. Within peatlands, Diademed Plovers were most often associated with headwaters. The top ranked occupancy model included constant detection, random spatial effects, and a single occupancy covariate: mean NDWI (Normalized Difference Water Index, an index correlated with water content and humidity) over the previous three years. Contrary to our prediction, Diademed Plovers preferred less water-saturated peatlands (lower NDWI), possibly to avoid nest flooding. This may be especially important in wet years, like the year when we conducted our surveys. Neither peatland size nor grazing by llamas and vicuñas affected peatland use by Diademed Plovers, suggesting that llama grazing at current levels may be compatible with plover conservation. For organisms that specialize on humid habitats, such as peatlands, factors affecting occupancy may vary temporally with variation in climate, and we recommend follow-up surveys across multi-year timescales to untangle the impact of climate on animals' use of humid habitats.
