Aim. To assess the contribution of individual socioeconomic parameters to the risk of death and cardiovascular events among Russian men and women aged 25-64, according to epidemiological study data.

Material and methods. The study was based on data from the prospective study ESSE-RF (2013-2014) and ESSE-RF2 (2017), which included a total of 22812 participants aged 25-64 years from 14 regions. The analysis assessed the following sociodemographic parameters: marital status, education level, income, employment, and type of settlement. From 2013 to 2021, 688 participants died. The composite endpoint (CE), including fatal and non-fatal (myocardial infarction and/or cerebrovascular accident) cardiovascular events, was registered in 470 (4,6%) men and 380 (2,4%) women. Associations with endpoints were assessed using Cox proportional hazards models with corresponding hazard ratios (HR).

Results. According to multivariate analysis, the following parameters were significantly associated with the all-cause death risk in the male population: non-marriage (HR 1,86, 95% confidence interval (CI): 1,48-2,33), no higher education (HR 1,34, 95% CI: 1,08-1,67), low income (HR 1,32, 95% CI: 1,06-1,63), non-employment (HR 1,97, 95% CI: 1,58-2,46); with CE — no higher education (HR 1,64, 95% CI: 1,34-2,01), nonemployment (HR 1,49, 95% CI: 1,21-1,84). In the population of women, a reliable contribution to all-cause death risk and CE occurrence was made by the lack of higher education and non-employment — HR 1,54, 95% CI: 1,17-2,04; HR 1,64, 95% CI: 1,26-2,14; HR 1,35, 95% CI: 1,07-1,71; HR 1,38, 95% CI: 1,1-1,73, respectively.

Conclusion. The study results indicate that the most unfavorable prognostic factors in relation to death risk and fatal and non-fatal cardiovascular events are the lack of higher education and nonemployment, regardless of sex and region of residence.

Aim. To study the changes of vascular stiffness, subclinical atherosclerosis, bone mineral density (BMD) and to identify cases of cardiovascular disease (CVD) manifestation over a 10-year period.

Material and methods. We analyzed 93 menopausal women without clinical manifestations of atherosclerosis at the study start, who underwent outpatient examination twice at the National Medical Research Center for Therapy and Preventive Medicine with an interval of 10 years. All women were surveyed for risk factors, fractures, and CVDs. In addition, pulse wave velocity and augmentation index were measured using applanation tonometry, carotid artery ultrasound to determine the intima-media thickness and register plaques, and BMD was measured using dual-energy X-ray absorptiometry.

Results. During the follow-up period, among the CVD risk factors, only the prevalence of hypertension increased by 32,2% (p<0,001). By visit 2, an increase in the augmentation index and intima-media thickness, the number of plaques (p<0,001), as well as a decrease in BMD in the femoral neck by 5,3% and in the proximal femur by 3,2% (p<0,001), but not in the spine, were noted. CVD were detected in 8 (9%) women.

Conclusion. This retrospective and prospective study demonstrated a significant increase in subclinical atherosclerosis, vascular stiffness, with the exception of pulse wave velocity, and a decrease in bone mass in postmenopausal women over a 10-year follow-up period.

Biological age has attracted increased attention of the medical community in recent years. It is individual for each person and currently there is no clear classification for dividing into groups that could help determine whether the rate of aging in a particular individual is normal or pathological. Today, scientists are conducting a large number of clinical and laboratory studies to find the optimal marker of biological aging that would meet all the requirements. The review aim is to analyze and summarize the available data on the mechanisms of aging, the development of novel markers of biological aging and calculators that can be used in routine practice in the future to prevent the development and progression of noncommunicable diseases.

Published: February 2025

The accumulation of biospecimens associated with large-scale clinical data (data from electronic medical records, epidemiological and other large-scale studies) has made it possible to conduct studies aimed at studying associations between genetic variants and phenotypes, in particular, phenome-wide association studies (PheWAS). It was originally designed to test one or more genetic variants associated with a disease or clinical symptom for associations with other phenotypes. PheWAS can identify novel genetic and phenotypic associations, differentiate true pleiotropy and clinical comorbidity, identify new disease subtypes, and identify new drug targets. Future efforts to integrate broad and robust phenotypic data collection and improve PheWAS tools will provide a valuable resource for more efficient genome-phenome analysis, leading to new discoveries in personalized medicine.

Aim. To assess post-vaccination period and the incidence of coronavirus disease 2019 (COVID-19) in comorbid individuals vaccinated and revaccinated against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Material and methods. The study was conducted within the prospective SATURN registry, which included individuals who received various revaccination regimens against the SARS-CoV-2 (homoand heterologous regimens) based on a combination of two vaccines (GamCOVID-Vac and CoviVac). A total of 200 respondents participated in the study, who were divided into 2 groups depending on the Charlson comorbidity index score. Group I included participants (n=172) with a score of 0-1, which implies a high percentage (99-96%) of survival in the next 10 years. Group II included participants (n=28) with a Charlson index score of 2-4, where the survival rate is significantly lower and varies from 90 to 53%.

Results. One year after vaccination (visit 3) and further in each of the groups, the anti-SARS-CoV-2 IgG level significantly exceeded the reference values (≥499 BAU/ml). The immunity durability was maintained throughout the entire follow-up period. The COVID-19 rate in the post-vaccination period (visit 3 and further) among the study participants varied from 0 to 50% of respondents in different groups (p>0,05). During the same time periods, according to the Hospital Anxiety and Depression Scale (HADS), the median of both anxiety and depression in each of the groups ranged from 0 to 7, which indicates the absence of severe symptoms of these conditions in most program participants. The prevalence of suband clinically pronounced depression did not differ between the groups at each visit. The incidence of clinical anxiety at visit 3 was significantly higher in the group of comorbid patients (16,7 vs 1,8%, p<0,05). However, during further follow-up in group II, there was not a single participant with clinical anxiety.

Conclusion. The use of Russian vaccines (Gam-COVID-Vac and CoviVac) is equally effective in each of the studied groups. There were no significant differences between them in COVID-19 incidence after vaccination/revaccination. When assessing the post-vaccination period, our attention was focused on the mental status of the participants. During one of the control visits at the revaccination stage (visit 3), the incidence of clinical anxiety in the group of comorbid patients (II) was higher. However, establishing the cause-and-effect relationships with other factors is currently difficult and requires further research.

In recent years, interoception, described as the ability to perceive signals from internal organs, has been actively studied. However, the relationship between cardiovascular diseases and neurophysiological characteristics of interoception remains poorly understood.

Aim. In this work, we studied neurophysiological markers of interoception in a group of patients with hypertension. Heart-evoked potentials (HEPs) were used as neurophysiological markers.

Material and methods. The study included 41 patients with HTN (2250 years old, 80,5% received antihypertensive therapy) and 41 people from the control group (26-50 years old), matched for sex and age. Interoception was studied at the behavioral level by heartbeat tracking task (HTT) and at the neuronal level by the electroencephalography method to record HEPs. Participants filled out the Toronto Alexithymia Scale questionnaire.

Results. No significant differences in the accuracy of heartbeat sensations and HEP amplitudes were found between the HTN and control group, as well as significant relationships between accuracy of heartbeat sensations and HEP amplitudes in both groups. Significant positive correlations were found between the HEP amplitudes and the alexithymia indices in both groups.

Conclusion. No differences in HEP amplitudes were found between the patients with hypertension and the control group. However, for the first time, a relationship was demonstrated between difficulties in recognizing emotions and HEP amplitudes in hypertensive patients, confirming the hypothesis about the interaction of these processes at insular cortex level.
Mortality from chronic ischaemic heart disease in the Russian Federation: are there enough data for analysis and decision-making?
Authors: Shepel R. N. , Samorodskaya I. V. , Kakorina E. P. , Drapkina O. M.
Published: February 2025

Aim. To discuss the role of coding the underlying cause of death based on International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10) in changing the standardized mortality rates (SMR) from various chronic ischaemic heart disease (CIHD) in the Russian Federation in 2014-2023.

Material and methods. The analysis of Rosstat data on the number of patients who died from CIHD and its individual forms for 2014-2023 was performed in accordance with the Brief Nomenclature of Causes of Death of Rosstat. The calculations were performed using the computer program "Calculation and Analysis of Mortality Rates and Years of Life Lost as a Result of Premature Mortality in the Subjects of the Russian Federation" developed at the National Medical Research Center for Therapy and Preventive Medicine. For SMR estimation, the World Health Organization European Standard Population (1976) was used. Accumulation, adjustment and systematization of the original information were carried out in Microsoft Office Excel 2016.

Results. In the Russian Federation as a whole, the SMR from CIHD decreased by 14,6% in 2014-2023 (from 196,2 to 167,5 per 100 thousand population). The share of CIHD in all-cause mortality did not change significantly, while its share in all ischaemic heart disease forms increased annually. We found a decrease in SMR from "I25.0 Atherosclerotic cardiovascular disease, so described" (by 82,5%), "I25.1 Atherosclerotic heart disease" (by 22,3%), "I25.9 CIHD, unspecified" (by 84,1%) against the background of an increase in the group of other forms of CIHD (I25.2-6.8) (by 40%) with an increase in the contribution of CIHD from 25,37 to 41,32%. The proportion of CIHD without clinical criteria (I25.0-1.9) remains high (~60%).

Conclusion. Tendencies towards a decrease in mortality from CIHD were revealed with an increase in the proportion of CIHD in all ischaemic heart disease forms. The share of unspecified codes and forms of CIHD as the cause of death has decreased. There is a need for uniform Russian guidelines, in which CIHD classification according to ICD-10 would be adapted to clinical terminology and the most probable clinical variants of the disease course and causes of death. Clarification of criteria and typification of coding approaches will contribute to a better understanding of the causes and subsequent adoption of targeted management decisions.

Authors: Davidovich I. M. , Korneeva N. V. , Kovaleva G. A. , Fedorchenko Yu. L.
Published: February 2025

Microcirculatory vessels make up about 99% of all vessels in the human body, so cardiovascular diseases at different stages affect microcirculation to varying degrees. The literature review presents studies of different years on microcirculation in heart failure (HF) using the following most popular methods: laser Doppler flowmetry, polarography, nailfold capillaroscopy, bulbar conjunctiva biomicroscopy, and in vitro laboratory tests. Taking into account the changed modern concept of HF and the classification adopted in recent years that assesses the left ventricular ejection fraction, the list of cited works shows gaps in data on microcirculation changes in chronic HF with preserved ejection fraction and prospects for further related research.
Issues of concern and development of classifications of the main parameters of therapy quality and compliance. Part III: quality of pharmacotherapy
Authors: Lukina Yu. V. , Kutishenko N. P. , Martsevich S. Yu. , Drapkina O. M.
Published: February 2025

This article is the third work in a series of publications on consideration of the main parameters of therapy quality and compliance and the development of their classifications. The aim is to determine, based on scientific literature data, the main parameters reflecting the quality of therapy and to develop their classification.

According to the World Health Organization, more than half of all drugs are prescribed and sold improperly, and half of all patients take their medications inadequately. To date, there is no generally accepted terminology and classification regarding the quality of therapy. The closest synonym for this concept is "rational/irrational pharmacotherapy". There are special scales and lists of criteria that reflect the quality of prescribed therapy and can be used to assess it. The main parameters of pharmacotherapy quality are the effectiveness and safety of treatment; some lists also include medication adherence. Data on the effectiveness and safety of drugs with proven efficacy for a certain disease are available in clinical guidelines. Information on aspects of drug safety is usually most fully presented in official instructions for medical products, which, along with clinical guidelines, are the main supporting documents in determining the quality parameters of pharmacotherapy. Also, a number of indices have been developed for the quantitative assessment of pharmacotherapy quality, both special (for certain diseases) and universal.

Based on the identified main parameters of pharmacotherapy quality, effectiveness and safety, as well as the subcategories of these parameters, we developed a classification.

The proposed classification of pharmacotherapy quality parameters can be used as a "roadmap" in prescription of pharmacotherapy and contribute to increasing its effectiveness, safety, personalization, i.e. pharmacotherapy quality in general. This will ultimately make it more likely to achieve the main goals of this treatment in real-world practice.
Different grazing schemes reinterpret rangeland ecology in the southern part of the Mexican Plateau
Authors: Riojas-López Mónica E. , Mellink Eric , Almanzor-Rojas David
Published: February 2025

Background: Grasslands are a major landscape component of the Mexican Plateau but has been impacted strongly by grazing. The specific effects on species composition of this have not been sufficiently elucidated. Such knowledge is needed for management and conservation.
Questions: What are the grass species composition and ground cover of grasslands along an intensive grazing – no grazing gradient?
Studied species: Poaceae
Study site and dates: Llanos de Ojuelos, Jalisco. 2016
Methods: Monthly surveys in 6 grassland sites, from severely overgrazed to 36 years without grazing.
Results: We recorded 24 species of grasses. Grama grasses were significantly the most abundant but there were inter-site differences. Purple muhly dominated the ungrazed site, while poverty threeawn dominated another site. Between 1 and 49 % of the ground was bare.
Conclusions: The differences in our sites allow a reinterpretation of the composition of mature, ungrazed grasslands in the area. Blue grama is touted as the climax species of regional grasslands. Until our survey, there was no evidence to consider any other grass species in this role. Our data support the view that dense prairies, rather than grasslands, were the XVI Century regional grasslands, dominated not by the blue grama, but by purple muhly, which is a decreaser under grazing by cattle, and was slowly replaced by grama grasses during the centuries ensuing the arrival of European livestock. Given their adaptation to grazing, blue grama was able to persist much longer in the systems.

Authors: Berelowitz Sharna , Franzsen Denise
Published: February 2025

AbstractIntroduction: Children with cerebral palsy (CP) have been found to present with visual perceptual impairments (VPI). Research indicates differences in VPI in various subtypes of CP. However, visual perceptual deficits in children with CP has not been investigated in terms of occupational therapy assessment and treatment in a South African context. The purpose of this study was to determine the specific VPI in learners ages 4-18 years with various subtypes of CP attending a school for learners with special needs in Johannesburg, South Africa.Method: The Test of Visual Perceptual Skills 3rd ed. (TVPS-3) was used to assess 80 learners and their subtest scores and composite scores were compared according to their subtype of CP as well as other demographic variables including age, gender and GMFCS level.Results: All the subtypes of CP were found to present with VPI, with the right spastic unilateral (hemiplegic) group having the fewest number of impairments and the ataxic group greatest number of impairments. A significant difference in visual discrimination and figure ground scores were found based on the subtype of CP while the Composite Basic Processes scores on the TVPS-3 differed significantly for both the subtypes of CP and gender. No significant differences were found for VPI based on age and GMFCS levels. Conclusion: Visual perceptual impairments were found in a high percentage of participants with CP with significant differences between the subtypes of CP and according to gender but not for age and GMFCS levels.Â Key words: Cerebral Palsy, Visual Perception, TVPS-3, Visual Perceptual Impairment, Occupational Therapy

Published: February 2025

ABSTRACTIntroduction: South African children with cancer are admitted to specialised oncology units for the duration of their treatment in the public health system. These units are thus a temporary environment for varying periods of time, which disrupts the children's participation in daily activities and consequently their Health Related Quality of Life (HRQoL).Methodology: A quantitative, descriptive, cross-sectional study was conducted in a tertiary hospital with a specialist oncology unit in Gauteng to determine the HRQoL of children admitted with cancer from their own and their parent's perspective. Structured interviews were conducted with the children aged 8-12 years using the PedsQLTM Generic Core Scale (4.0) and Cancer Module (3.0). The parent's perspective was explored using the Parents proxies form of the PedsQLTM scales.Results: Twenty-five children and their parents participated in the study. Most children in the sample were males and Leukaemia and chemotherapy being the most common diagnosis and treatment received. All children and parents reported the children's functioning at an intermediate level on the Generic Core Scale (4.0) and on the Cancer Module (3.0) that schooling and emotional functioning were most affected. This suggests that these children are at risk for HRQoL deficits.Â  This study also found that parents under- and over-estimated their children's HRQoL in various domainsConclusion: This study indicates the need for occupational therapists to understand the occupational disruption experienced by children during the treatment of cancer and monitor and provide support for this, to reduce the effect of impaired HRQoL.

Notes on the genera Ammobatoides and Melitturga in Europe (Hymenoptera: Apoidea)
Authors: Wood Thomas , Patiny Sébastien
Published: February 2025

The bee genus Ammobatoides Radoszkowski (Apidae) is a species-poor Old World group that predominantly parasitises the pollen-collecting genus Melitturga Latreille (Andrenidae). Nine species of Ammobatoides are currently recognised, but due to the rarity of most species, four are only known from a single sex. Examination of material from Greece has yielded the previously unknown female of Ammobatoides okalii Kocourek, a species previously known only from its male holotype. The suspected host is Melitturga spinosa Morawitz. Revised identification keys for Ammobatoides and Melitturga in Europe are provided, along with a clarification of the statuses and distributions of Melitturga praestans Giraud and Melitturga syriaca Friese.
A Case Report on Hemochromatosis Presenting with Diabetes Mellitus and Secondary Amenorrhea
Authors: Debleena Paul Paul , Saikia Uma Kaimal , Bhuyan Ashok Krishna , Abhamoni Baro Agarwal
Published: February 2025

Hemochromatosis is an iron storage disorder characterized by excessive iron absorption and deposition, leading to tissue damage and organ failure. Here we report a case of a 35-year-old female with a 6-year history of diabetes mellitus and secondary amenorrhea, along with chronic liver dysfunction and severe anemia requiring frequent blood transfusions. Clinical evaluation revealed severe pallor, hepatosplenomegaly, and hypogonadism. Laboratory findings indicated severe anemia (hemoglobin 4.8 g/dL), elevated serum ferritin (>1000 ng/ml), and high transferrin saturation (82.02%). Hormonal assays confirmed secondary hypogonadism with low FSH and LH levels. Imaging and liver biopsy demonstrated iron overload, and genetic testing identified SLC40A1 mutation, confirming hereditary hemochromatosis type 4, alongside beta-thalassemia minor. The patient was managed with deferasirox for iron chelation, insulin therapy for diabetes, and hormone replacement for hypogonadism. This case highlights the importance of considering hemochromatosis in patients with diabetes, liver dysfunction, and hypogonadism, especially in the context of anemia and frequent transfusions. Early diagnosis and treatment are crucial to prevent complications and improve outcomes. Genetic testing and liver biopsy play key roles in confirming the diagnosis, particularly in non-HFE hemochromatosis. This report underscores the need for a high index of suspicion in similar clinical presentations to ensure timely intervention.

This study investigates the axial compression behavior of hollow steel columns (HSCs) with and without defects, specifically horizontal and vertical slits, and strengthened using Glass Fiber Reinforced Polymer (GFRP) wrapping. Twelve specimens were tested for failure under axial compression. The parameter varied in the study are circular and square sections and type of slit. Experimental and finite element analyses (FEA) were performed to evaluate the structural performance of intact and defective columns. The load-carrying capacity HSC with a horizontal slit was increased by 20 % when compared to the control specimen without a slit. GFRP wrapping was applied in three plies to enhance load-bearing capacity by 50 % and mitigate the effects of structural deficiencies. The results demonstrated that GFRP significantly improved the axial load capacity and ductility of the columns, particularly in defective specimens, by reducing stress concentrations around the slits. Failure modes were analyzed, showing delayed local buckling, reduced plastic hinge formation, and controlled rupture or delamination of GFRP layers. FEA simulations in ANSYS replicated the experimental behavior accurately with a minimal error of less than 5%, providing insights into stress distribution, load–axial deflection characteristics, and failure mechanisms. This study underscores the effectiveness of GFRP wrapping as a strengthening technique for improving the performance and reliability of deficient CHSCs.

Published: February 2025

This article analyzes the evolution of English proficiency in economics graduates in Colombia in the 2010s using the results of the Saber Pro tests and the Relative Distributions Method (RDM). When comparing the distribution of the results at the beginning of the decade (2010-2011) with the end (2019-2020), significant changes were found in the distribution of the results. There is evidence of an increase in pre-intermediate to pre-advanced performance levels and a decrease in the basic level. In addition, differences were identified between official and non-official Higher Education Institutions. A clear relationship between accreditation and the distribution of results in English is also identified. This article contributes to the literature by being the first to study the evolution of the distribution of the results of performance levels in English using the RDM non-parametric technique. In addition, it is the first to present an analysis of the evolution of competence development during the 2010s.
Efectos de la política monetaria con metas de inflación en los retornos del mercado bursátil
Authors:   Universidad César Vallejo, Rodríguez Rafael
Published: February 2025

El objetivo de este artículo es estudiar los efectos de la política monetaria con metas de inflación en los retornos del mercado bursátil peruano para el período 2012-2023. Siguiendo la metodología de estudio de eventos, se trabajó con 70 observaciones de la tasa de referencia y 70 observaciones de los retornos del índice S&P/Peru Gen. Con base a la hipótesis del mercado eficiente, se separó la información en sus componentes esperado e inesperado. Siguiendo a Kuttner (2001) se estimó un proxy para el componente inesperado a partir de las tasas de interés interbancarias. Se concluye que un incremento de 1% en la tasa de interés genera un incremento de 0,277% en los retornos del mercado y viceversa, existiendo una relación positiva estadísticamente significativa. Los resultados sugieren que la BVL es un mercado eficiente y que el mercado bursátil no siempre responde a la política monetaria según lo establecido por la teoría.

Libraries, all over the world, are facing challenges to provide efficient and customized services to the users. Artificial Intelligence (AI) appears to be a transformative force with the ability to overhaul library operations and enhance user experience. However. AI has various limitations. Debates related to the application of AI in libraries, especially on the question of whether AI applications make library services better are on. This article examines the current development of AI and its application in improving various library services. AI has the capability to improve some services of the library like search capabilities, customise recommendations, data analytics and virtual reference service. However, AI in its current form cannot replace the indispensable role played by the library and information professionals in providing personalised services with a human touch, services which require cognitive and strategic thinking, guiding difficult searches, answering various follow-up queries, organising collections, and ensuring ethical considerations. This article examines the weakness of current AI with examples. It concludes that AI has the potential, but it cannot be applied in every domain of library services and more research needs to be done on this subject to help libraries in the responsible adoption of AI.

Reseña. José Luis LOSADA PALENZUELA, Schopenhauer traductor de Gracián. Diálogo y Formación, Valladolid, Universidad de Valladolid, Secretariado de Publicaciones e Intercambio Editorial, 2011, 296 páginas
Authors: Pueyo Sahún Paloma
Published: February 2025

Schopenhauer traductor de Gracián. Diálogo y Formación recoge un estudio sobre la relación dialogal entre Schopenhauer y Baltasar Gracián a través de las traducciones del filósofo aleman. El jesuita es un autor moderno y la valoración y difusión de su obra en Europa se deben, en gran parte, a la labor de este, quien reconoce en él a un autor universal y observa en sus obras aspectos morales del hombre aplicables a todos los individuos.

Los Emblemata (Frankfurt, 1596) de Dionysius Lebeus Batillius: Clasicismo, Neoestoicismo, Calvinismo
Authors: Antón Martínez Beatriz
Published: February 2025

Los Emblemata (Frankfurt, 1596) del juez calvinista Dionysius Lebeus Batillius, libro que clausura el siglo de oro de la emblemática francesa, son por primera vez objeto de un pormenorizado estudio en el que, a la luz de la biografía del autor y de su encuentro con el emblematista Janus Jacobus Boissardus, se presta atención a la génesis, a la estructura y al método de composición, al contenido y a las fuentes directas e indirectas; asimismo se señalan las notables diferencias entre esta editio princeps y la segunda edición (Heidelberg, 1600). A modo de breve antología se añade una selección de emblemas, cuyo análisis pone de manifiesto la pasión del autor por la Antigüedad clásica, su preferencia por el Neoestoicismo y su compromiso, cauteloso y disimulado, i.e. propio de un nicodemita, con la Iglesia Reformada.
Celar, mostrar, desvelar...: estrategias de remodelización verbo-visual en la Emblemática áurea
Authors: Ledda Giuseppina
Published: February 2025

Examino en la primera parte emblemas y empresas cuyos signos se presentan descontextualizados, parte de un todo ausente; con un mensaje moral, civil o mundano que queda envuelto enigmáticamente en pocos objetos o fragmentos aislados y sin trasfondo, o que destacan en un contexto ajeno, siguiendo modalidades deconstructivas propias del surrealismo. En la segunda parte muestro operaciones de descentramiento y sustitución, de supresión o permutación de elementos primarios o secundarios respecto a su lugar y papel habituales, según la tradicional convención iconográfica o histórico-narrativa. Comparo, en fin, los emblemas examinados con otros de marcada potencialidad ilustrativa, narrativos y escenográficos.

Las dos partes del Lazarillo de Tormes, la Reforma Protestante y la atribución a Francisco de Enzinas
Authors: Rodríguez López-Vázquez Alfredo
Published: February 2025

Analizamos elementos léxicos y estilísticos de las dos partes del Lazarillo de Tormes comparándolas con la traducción de Luciano de Samósata hecha por Francisco de Enzinas y con las memorias del propio Enzinas y concluimos que ambas partes son obra de este autor, y que el contenido ideológico y doctrinal se adscribe a la Reforma Protestante, de la que Enzinas, discípulo de Melanchton y amigo de Calvino y Bucero, era el máximo exponente en lengua castellana.
Reyes de bronce: tres poemas escultóricos de Quevedo
Authors: J. Sáez Adrián
Published: February 2025

Dentro de la poesía escultórica de Quevedo, los sonetos dedicados a las estatuas de Felipe III y Carlos V (núms. 211-212 y 214) forman un tríptico muy significativo entre el arte y la política con el que se abre El Parnaso español: este trabajo examina la construcción de los poemas, las ideas artísticas manejadas y algunas relaciones intertextuales con una silva de Estacio (para la primera pareja poemática) y el Tratado de las estatuas antiguas de Villalta (para el tercero), amén de otros guiños quevedianos.
El teatro clásico español en la escena nacional contemporánea: de la decadencia en la Transición al esplendor actual
Authors: Mascarell Purificació
Published: February 2025

En este artículo se reúnen por primera vez las causas dispersas del abandono escénico de los autores clásicos españoles durante la década de los setenta, su progresiva recuperación a lo largo de los 80 y 90, y su consolidación artística y social a partir del cambio de milenio. El trabajo expone las razones que influyeron en este proceso de recuperación y realiza un balance de la cartelera, desde 1975 hasta el presente, para constatar el auge actual del teatro barroco en España.

Los colores en la heráldica de los libros de caballerías
Authors: López-Fanjul de Argüelles Carlos
Published: February 2025

Se analiza en detalle el simbolismo expresado mediante los colores del campo del escudo y la cota de armas de los personajes de 36 libros de caballerías impresos en el siglo XVI, y se comparan las preferencias cromáticas literarias con las observadas en la heráldica castellana real compuesta durante ese mismo periodo y también con las desarrolladas previamente en las novelas del ciclo artúrico. Las correspondencias entre colores y sentimientos  propuestas por los tratadistas del siglo XV tuvieron una influencia determinante en el entintado de los escudos novelescos, pero afectaron muy poco a la coloración de los auténticos, exceptuando la promoción de un decidido gusto por el verde que, sin embargo, careció de intenciones simbólicas. El uso de alegorías cromáticas fue mucho más amplio en los libros de caballerías que en la literatura artúrica y la elección de colores en cada caso respondió a propósitos generalmente diferentes.
Humanidades Digitales y Literatura española: 50 años de repaso histórico y panorámica de proyectos representativos
Authors: Hernández Lorenzo Laura
Published: February 2025

Este trabajo presenta un estado de la cuestión de las aplicaciones de las Humanidades Digitales a la Literatura española a través de un repaso histórico de los últimos 50 años y una panorámica de principales proyectos y líneas de investigación en este ámbito. Con este fin, la emergencia e historia de las Humanidades Digitales en España se organiza en tres fases: los orígenes (1970-2011), hacia la institucionalización (2011-2015) y consolidación y nuevos retos (2015-2020). Debido a la amplitud y variedad de los proyectos existentes, se aspira a ofrecer una muestra significativa de los más relevantes en términos de actualidad, interés para el estudio de la Literatura española (con especial atención al Siglo de Oro), visibilidad, y acceso abierto, a través de cuatro categorías fundamentales: bases de datos, bibliotecas digitales, ediciones digitales y enfoques cuantitativos.
