ABSTRACT Cardiovascular diseases continue to be the leading cause of morbidity and mortality worldwide. Although there are therapeutic and pharmacological tools that help control the incidence of cardiovascular outcomes by reducing cardiovascular risk, inequities in timely access to healthcare services and social determinants of health prevent the entire population in need from receiving this therapeutic assistance. Thus, non-pharmacological interventions are prioritized, among which the diet stands out, as it has been shown to significantly influence cardiovascular health and life expectancy. Particularly, the Mediterranean diet, primarily based on the consumption of fruits, vegetables, grains, legumes, olive oil, spices, followed by fish and seafood-derived protein, has demonstrated a certain degree of protection against cardiometabolic diseases. However, the impact on a population with high cardiovascular risk and established cardiovascular disease remains uncertain. Considering the evolving evidence on dietary patterns and the need to understand how viable diets in our context affect individuals with a higher risk of morbidity and mortality from cardiovascular disease, the objective of this review is to present updated evidence on the benefits of the Mediterranean diet in individuals with high cardiovascular risk. For this purpose, a literature search was performed in the PubMed, Science Direct, and Scielo databases.

RESUMEN Las enfermedades cardiovasculares siguen siendo la principal causa de morbilidad y mortalidad en el mundo. Y aunque existen herramientas terapéuticas y farmacológicas que ayudan a controlar la incidencia de desenlaces cardiovasculares con la reducción del riesgo cardiovascular, las inequidades en el acceso oportuno a servicios de salud y de determinantes sociales de la salud impiden que toda la población con esta necesidad pueda recibir esta ayuda terapéutica. Es así, como se da prioridad a las intervenciones no farmacológicas, dentro de las que se destaca, la dieta, la cual ha demostrado influir significativamente en la salud cardiovascular y en la expectativa de vida del ser humano. Particularmente, la dieta mediterránea, basada esencialmente en el consumo de frutas, vegetales, granos, legumbres, aceite de oliva, especias, seguido de proteína derivada de pescado y comida de mar, ha demostrado proveer cierto grado de protección frente a enfermedades cardiometabólicas. Sin embargo, se desconoce con certeza cuál es el impacto en la población con elevado riesgo cardiovascular y, por ende, enfermedad cardiovascular establecida. Considerando la evolución de la evidencia en los patrones dietarios, así como la necesidad de conocer qué tanto impactan las dietas viables en nuestro medio, sobre todo en aquellos con mayor riesgo de morbilidad y mortalidad por enfermedad cardiovascular, el objetivo de esta revisión consiste en exponer evidencia actualizada sobre los beneficios de la dieta mediterránea en individuos con elevado riesgo cardiovascular. Para esto, se realizó una búsqueda bibliográfica en las bases de datos PubMed, Science Direct y Scielo.

Abstract: This work aims to show that there are a good number of arguments to sustain that the criminal prosecution of tax offenses punishable with prison sentences -and the necessity for criminal prosecution to be just initiated by complaint or plaint of Internal Revenue Service or State Defense Council- generates a risk zone for antidemocratic populist actions.

Resumen: Este trabajo pretende mostrar que hay un buen número de argumentos para sostener que la persecución penal de los delitos tributarios sancionadas con pena privativa de libertad para cuyo inicio se exige denuncia o querella del Servicio de Impuestos Internos -o del Consejo de Defensa del Estado a su requerimiento-, genera una zona de riesgo de acciones populistas antidemocráticas.

ABSTRACT The Northeastern Pacific (NEP) population of white sharks (Carcharodon carcharias) is genetically distinct from the rest of the world. This uniqueness results from adult fidelity to central California and Guadalupe Island aggregations sites. The strong mitochondrial genetic structure between the white sharks of central California and Guadalupe Island is also present, which indicates female philopatry. To date, few studies using nuclear DNA have found evidence of genetic patterns in the NEP white shark population, which could indicate that these sharks exhibit sex-biased dispersal. In this study, we evaluated the genetic structure, connectivity, and genetic diversity of NEP white sharks using samples from the southern California Bight (SCB), Baja California (including Sebastian Vizcaino Bay), the Gulf of California, and Guadalupe Island (GI) using nDNA (i.e. microsatellite loci). A total of five loci were successfully genotyped in 54 individuals. The patterns found in this study indicated low levels of genetic diversity among all localities (observed heterozygosity: Ho = 0.47), likely due to a founder effect. A slight genetic structure was present for NEP localities in this study (FST = 0.045, P = 0.0001), mainly identified between the SCB and GI locations. A sibship assignment analysis indicated low and moderate probabilities of full- and half-siblings between white shark juveniles from coastal areas, suggesting a high degree of connectivity between nursery areas in the NEP. Our results suggest that juveniles can mask the genetic structure in coastal zones.

Abstract Background: The generic boundaries and phylogenetic relationships of Clinopodium are still unstable. There are 15 species recorded in Mexico, which were also treated under the genera Calamintha or Satureja. Recent botanical explorations in western Mexico led to the discovery of an additional species which possesses relatively long corollas, reddish in color, this morphological pattern fits into the species set previously known as Satureja sect. Gardoquia. Questions: what are the diagnostic morphological characters that support the new species? Which are the species morphologically similar? Studied species: species of Clinopodium inhabiting in Mexico and those belonging to Satureja sect. Gardoquia. Study site and dates: San Sebastián del Oeste, Jalisco, Spring 2022. Methods: Botanical collects, herborization and morphological characterization of the specimens collected. Comparison with specialized literature, herbarium specimens and nomenclatural types online. Results: The new species Clinopodium haraverianum is distinguished from the other species in the genus by the combination of the following characters: herbaceous habit, stem not branched, leaves progressively reduced in size towards the apex of the stem, calyx strongly bilabiate, corollas with a tube longer than 16 mm and reddish. The most similar species is C. macrostemum, to which it is compared in the diagnosis. Conclusions: Clinopodium haraverianum is set apart from most of the species of Clinopodium by presenting the characters defining the group Gardoquia, and within this, it differs by the habit and size of floral structures. This species constitutes and addition to the endemic flora of Jalisco and consequently of Mexico.

Resumen: Antecedentes: La delimitación genérica y las relaciones filogenéticas de Clinopodium son aún inestables. En México se registran 15 especies que alguna vez fueron tratadas también bajo los géneros Calamintha o Satureja. Exploraciones recientes en el occidente de México condujeron al descubrimiento de una especie adicional con corolas relativamente largas y de tono rojizo, lo que corresponde al conjunto antes reconocido como Satureja sect. Gardoquia. Preguntas: ¿cuáles son las características morfológicas diagnósticas que soportan a la especie nueva?, ¿cuáles son las especies morfológicamente similares? Especies de estudio: especies de Clinopodium de México y de Satureja sect. Gardoquia. Sitio y años de estudio: San Sebastián del Oeste, Jalisco, primavera de 2022. Métodos: Recolección botánica, herborización y caracterización morfológica de los especímenes recolectados. Cotejo de literatura especializada, ejemplares de herbario y tipos nomenclaturales en línea. Resultados: La especie nueva Clinopodium haraverianum se distingue del resto de especies del género por la combinación de los siguientes caracteres: hábito herbáceo no ramificado, hojas progresivamente reducidas hacia el ápice del tallo, cáliz marcadamente bilabiado, corolas con el tubo mayor de 16 mm de largo y de tono rojizo. La especie más parecida es C. macrostemum con la que se compara en la diagnosis. Conclusiones: Clinopodium haraverianum se separa de la mayoría de las especies de Clinopodium al reunir las características que definen al grupo Gardoquia, y dentro de este destaca por su hábito y tamaño de las estructuras florales. Esta especie constituye una adición a la flora endémica de Jalisco y por extensión de México.

ABSTRACT Emotional intelligence is defined as the ability to know and master one’s and/or others' emotions. The objectives of this study were to validate an emotional intelligence instrument in a sample of physical education students from Chile, and to describe the emotional skills of the sample. 226 physical education students from two universities in Santiago de Chile were evaluated. The Emotional Metacognition Trait Scale (TMMS-24) was applied. The results reveal that the instrument, reduced to 19 items, presents three factors that explain 56,8% of the total variance, with a Cronbach alpha of 0,916. In relation to the levels of emotional intelligence, the sample presents high values, without there being significant differences in the dimension’s clarity, attention, and repair of the TMMS-24 between women and men. When comparing years of career, there are only differences in the clarity dimension, where 5th year students had higher scores than/as 2nd years. It is concluded that physical education students have high rates of emotional intelligence, with no differences between women and men.

Resumen Introducción y objetivos: Ligustrum sinense (ligustrina) es una reconocida especie exótica invasora. El objetivo de este trabajo fue estudiar los rasgos fisiológicos y anatómicos foliares de renovales de ligustrina que podrían otorgarle ventajas para su establecimiento en un ambiente de sotobosque de la selva de Yungas. M&M: Este estudio se realizó en el Parque Nacional Aconquija (Tucumán, Argentina). Se evaluaron los rasgos morfo-anatómicas foliares y fisiológicos en un ambiente de sotobosque durante primavera-verano e invierno. Se analizaron las características anatómicas de la lámina foliar y variables fisiológicas relacionadas al intercambio de gases. Además, se calculó el área foliar específica, densidad de hojas, contenido de nitrógeno foliar y eficiencia fotosintética en el uso del nitrógeno foliar. Resultados: Durante primavera-verano L. sinense muestra una mayor eficiencia fotosintética en el uso del nitrógeno foliar y una mayor asimilación fotosintética en condiciones saturantes. La eficiencia de carboxilación, eficiencia intrínseca del uso del agua y espesor de hoja fueron 26%, 34% y 41% mayores en invierno con relación a primavera-verano. Durante el invierno se registró un aumento en el espesor de la lámina lo que contribuiría a mejorar el intercambio de CO2 bajo condiciones subóptimas para la fotosíntesis. Conclusiones: La ligustrina fotosintetiza todo el año y su éxito para establecerse en el sotobosque de la selva de Yungas podría explicarse en parte por las estrategias morfo-anatómicas y fisiológicas desplegadas.

Summary Background and aims: Ligustrum sinense (Chínese privet) is a recognized invasive exotic species. The objective of this study was to determine the physiological and foliar anatomical traits of Chinese privet saplings that would give it an advantage for its establishment in the understory of the Yungas forest environment. M&M: This study was conducted in Parque Nacional Aconquija (Tucumán, Argentina). The foliar physiological and morpho-anatomical traits deployed were investigated in an understory environment during spring-summer and winter. The anatomical features of the leaf blade and physiological variables related to gas exchange were analyzed. Also, the specific leaf area, leaf density, leaf nitrogen content and photosynthetic nitrogen-use efficiency were calculated. Results: During spring-summer L. sinense displays a higher photosynthetic assimilation rate and a better photosynthetic nitrogen-use efficiency. Carboxylation efficiency, intrinsic water use efficiency, and leaf thickness were 26%, 34%, and 41% higher, respectively, during winter in contrast to spring-summer. In the winter an increase in leaf thickness contributed to improved CO2 incorporation under suboptimal conditions for photosynthesis. Conclusions: Chinese privet undergoes photosynthesis throughout the year and its success as an invasive species in the Yungas forest understory could be attributed at least in part to morpho-anatomical and physiological strategies.

Resumen: Para las y los autores de este proyecto, ganador del concurso para albergar la obra del escultor Mario Irarrázabal, un museo puede entenderse como un jardín -definido por sus límites, pero también abierto al cambio-. Para nosotros en ARQ, este proyecto también demuestra cómo los edificios pueden ser herramientas para la recuperación ecológica, donde las lógicas de emplazamiento, circulación y redes de infraestructura se tratan como oportunidades para favorecer a las especies más-que-humanas que ya habitan este lugar.

Abstract: For the authors of this winning competition entry to house sculptor Mario Irarrázabal’s work, a museum can be understood as a garden -defined by its limits but also open to change. For us at ARQ, this project also demonstrates how buildings can be tools for ecological recovery, wherein the logic of their positioning, circulation, and infrastructural networks are treated as opportunities to favor the more-than-human species that already inhabit the site.

Resumen Los riñones ectópicos pélvicos solitarios asociados a degeneración aneurismática de las arterias ilíacas y la aorta abdominal son eventos muy raros. Los enfoques quirúrgicos para la corrección de aneurismas con compromiso renal son un desafío por la falta de consenso actual, en especial cuando cursan con riñones ectópicos pélvicos solitarios funcionales asociados. Por tal motivo, una de las estrategias que ha demostrado buenos resultados a corto y mediano plazo es la nefroprotección en frío, la cual puede ser usada con seguridad en estos pacientes. En el caso que se presenta, se evidenció una ectasia aórtica con aneurismas ilíacos bilaterales asociados con un riñón ectópico pélvico solitario en un paciente masculino de 75 años, con hipertensión arterial y dislipidemia. Se realizó una reconstrucción aortoilíaca bilateral y una reconstrucción de la arteria hipogástrica, además de reimplante de la arteria renal ectópica bajo irrigación renal en frío, sin complicaciones y preservación de la función renal.

Abstract Solitary pelvic ectopic kidneys associated with aneurysmal degeneration of the iliac arteries and abdominal aorta are very rare events. Surgical approaches for the correction of aneurysms with renal involvement are challenging due to the lack of current consensus, especially when they are associated with functional solitary pelvic ectopic kidneys. For this reason, one of the strategies that has shown good results in the short and medium term is cold nephroprotection, which can be used safely in these patients. In the present case, aortic ectasia with bilateral iliac aneurysms associated with a solitary pelvic ectopic kidneys was evidenced in a 75-year-old male patient with arterial hypertension and dyslipidemia. Bilateral aortoiliac reconstruction was performed with hypogastric artery reconstruction and reimplantation of the ectopic renal artery under cold renal irrigation, without complications and preservation of renal function.

Background: Long-term outcomes of Off-Pump Coronary Artery Bypass Grafting (OPCAB) as an alternative to the traditional Coronary Artery Bypass Grafting (CABG) technique with cardiopulmonary bypass (CPB) are not well defined. Aim: To compare 10-year survival of isolated OPCAB versus CABG with CPB. Material and Methods: Analysis of information obtained from databases, clinical records and surgical protocols of patients treated with isolated CABG between January 2006 and November 2008 at a Regional Hospital. Of 658 isolated CABG, 192 (29.2%) were OPCAB and 466 (79.9%) CPB. Propensity Score Matching (PSM) was performed to compare both groups. After PSM, two groups of 192 cases were obtained. Mortality data was obtained from the Chilean public identification service. Ten-year survival was calculated and compared with Kaplan-Meier and log-rank methods. Results: Follow-up data was obtained in all cases. No statistically significant differences were found when comparing 10-year survival between OPCAB versus CPB (78.6% and 80.2% respectively, p 0.720). There was also no statistical difference in cardiovascular death free survival (90.1% with CPB versus 89.1% OPCAB, p 0.737). Survival was comparable when analyzing subgroups with diabetes mellitus, left ventricular dysfunction or chronic kidney disease, among others. Conclusions: In our series, OPBAB has a comparable 10-year survival with CABG with CPB.

Resumen: La adquisición de una nueva morbilidad (NM) se ha convertido en una medida de resultado clínico fundamental después de la enfermedad crítica pediátrica. Los datos en niños latinoamericanos son aún escasos. Objetivo: analizar el desarrollo de nuevas morbilidades adquiridas tras hospitalización por Infección del Tracto Respiratorio Inferior (ITRI) en unidades de cuidados intensivos pediátricos (UCIP). Pacientes y Método: Se incluyeron pacientes de 35 UCIP de 8 países, edades 0 a 18 años con diagnóstico de ITRI, dados de alta vivos, registrados entre abril 2018 y septiembre 2019, y que hayan requerido algún tipo de soporte ventilatorio (sistema de alto flujo, ventilación no invasiva o ventilación invasiva), incluidos en el registro de LARed Network, que incluye la Escala de Estado Funcional (FSS en inglés) validada en población pediátrica, que evalúa el estado funcional en seis dominios: estado mental, sensorial, comunicación, motor, alimentación y estado respiratorio. NM consideró ITRI posterior a su hospitalización y se definió como un incremento ≥ 3 puntos en la FSS. Resultados: De 3280 niños con ITRI, 85 (2,6%) desarrollaron NM, asociada a diagnósticos de sepsis y síndrome de dificultad respiratoria aguda (SDRA), infección por neumococo o por adenovirus, infecciones asociadas a la atención en salud y ventilación mecánica invasiva. La infección por adenovirus, el SDRA y las IAH se asociaron de forma independiente con NM. Conclusiones: Observamos que el desarrollo de NM al egreso de UCIP es infrecuente, pero está asociada a factores de riesgo modificables. Estos datos definen ciertos grupos de riesgo para realizar futuras intervenciones e iniciativas en la mejora de la calidad de atención.

Abstract: Acquisition of new morbidity (NM) has become a key clinical outcome measure after pediatric critical illness. Data on Latin American children are still scarce. Objective: to analyze the development of new morbidities acquired after hospitalization due to lower respiratory tract infection (LRTI) in pediatric intensive care units (PICU). Patients and Method: we included patients from 35 PICUs from 8 countries, aged 0 to 18 years with a diagnosis of LRTI, discharged alive, registered between April 2018 and September 2019, and who required some type of ventilatory support (high-flow system, noninvasive ventilation or invasive ventilation), included in the LARed Network registry, which includes the Functional Status Scale (FSS) validated in the pediatric population, which assesses functional status in six domains: mental status, sensory, communication, motor skills, feeding, and respiratory status. NM considered LRTI after hospitalization and was defined as an increase of ≥ 3 points in the FSS. Results: Of 3280 children with LRTI, 85 (2.6%) developed NM, associated with diagnoses of sepsis and acute respiratory distress syndrome (ARDS), pneumococcal or adenovirus infection, healthcare-associated infections (HAIs), and invasive mechanical ventilation. Adenovirus infection, ARDS, and HAIs were independently associated with NM. Conclusions: We observed that the development of NM at PICU discharge is infrequent but is associated with modifiable risk factors. These data define certain risk groups for future interventions and initiatives to improve the quality of care.

Abstract Background Despite representing the largest fraction of animal life, the number of insect species whose genome has been sequenced is barely in the hundreds. The order Dermaptera (the earwigs) suffers from a lack of genomic information despite its unique position as one of the basally derived insect groups and its importance in agroecosystems. As part of a national educational and outreach program in genomics, a plan was formulated to engage the participation of high school students in a genome sequencing project. Students from twelve schools across Chile were instructed to capture earwig specimens in their geographical area, to identify them and to provide material for genome sequencing to be carried out by themselves in their schools. Results The school students collected specimens from two cosmopolitan earwig species: Euborellia annulipes (Fam. Anisolabididae) and Forficula auricularia (Fam. Forficulidae). Genomic DNA was extracted and, with the help of scientific teams that traveled to the schools, was sequenced using nanopore sequencers. The sequence data obtained for both species was assembled and annotated. We obtained genome sizes of 1.18 Gb (F. auricularia) and 0.94 Gb (E. annulipes) with the number of predicted protein coding genes being 31,800 and 40,000, respectively. Our analysis showed that we were able to capture a high percentage (≥ 93%) of conserved proteins indicating genomes that are useful for comparative and functional analysis. We were also able to characterize structural elements such as repetitive sequences and non-coding RNA genes. Finally, functional categories of genes that are overrepresented in each species suggest important differences in the process underlying the formation of germ cells, and modes of reproduction between them, features that are one of the distinguishing biological properties that characterize these two distant families of Dermaptera. Conclusions This work represents an unprecedented instance where the scientific and lay community have come together to collaborate in a genome sequencing project. The versatility and accessibility of nanopore sequencers was key to the success of the initiative. We were able to obtain full genome sequences of two important and widely distributed species of insects which had not been analyzed at this level previously. The data made available by the project should illuminate future studies on the Dermaptera.

Abstract Background Sepsis is an uncontrolled inflammatory response against a systemic infection that results in elevated mortality, mainly induced by bacterial products known as endotoxins, producing endotoxemia. Disseminated intravascular coagulation (DIC) is frequently observed in septic patients and is associated with organ failure and death. Sepsis activates endothelial cells (ECs), promoting a prothrombotic phenotype contributing to DIC. Ion channel mediated calcium permeability participates in coagulation. The transient reception potential melastatin 7 (TRPM7) non-selective divalent cation channel that also contains an α-kinase domain, which is permeable to divalent cations including Ca2+, regulates endotoxin-stimulated calcium permeability in ECs and is associated with increased mortality in septic patients. However, whether endothelial TRPM7 mediates endotoxemia-induced coagulation is not known. Therefore, our aim was to examine if TRPM7 mediates coagulation during endotoxemia. Results The results showed that TRPM7 regulated endotoxin-induced platelet and neutrophil adhesion to ECs, dependent on the TRPM7 ion channel activity and by the α-kinase function. Endotoxic animals showed that TRPM7 mediated neutrophil rolling on blood vessels and intravascular coagulation. TRPM7 mediated the increased expression of the adhesion proteins, von Willebrand factor (vWF), intercellular adhesion molecule 1 (ICAM-1), and P-selectin, which were also mediated by the TRPM7 α-kinase function. Notably, endotoxin-induced expression of vWF, ICAM-1 and P-selectin were required for endotoxin-induced platelet and neutrophil adhesion to ECs. Endotoxemic rats showed increased endothelial TRPM7 expression associated with a procoagulant phenotype, liver and kidney dysfunction, increased death events and an increased relative risk of death. Interestingly, circulating ECs (CECs) from septic shock patients (SSPs) showed increased TRPM7 expression associated with increased DIC scores and decreased survival times. Additionally, SSPs with a high expression of TRPM7 in CECs showed increased mortality and relative risk of death. Notably, CECs from SSPs showed significant results from the AUROC analyses for predicting mortality in SSPs that were better than the Acute Physiology and Chronic Health Evaluation II (APACHE II) and the Sequential Organ Failure Assessment (SOFA) scores. Conclusions Our study demonstrates that sepsis-induced DIC is mediated by TRPM7 in ECs. TRPM7 ion channel activity and α-kinase function are required by DIC-mediated sepsis-induced organ dysfunction and its expression are associated with increased mortality during sepsis. TRPM7 appears as a new prognostic biomarker to predict mortality associated to DIC in SSPs, and as a novel target for drug development against DIC during infectious inflammatory diseases.
