Isotopic profiling of natural uranium mined from northern Nigeria for nuclear forensic application
Authors: John Samuel O.O. , Usman Iyabo T. 
Published: March 2022

Four mined samples of natural uranium from northern Nigeria were studied through inductively coupled plasma mass spectrometry, at the Environmental Analytical Chemistry Laboratory, University of the Witwatersrand, Johannesburg. The samples were characterised for lead, thorium and uranium isotopic concentrations, isotopic ratios and age. The objective was to obtain nuclear forensic fingerprints as baseline data to add to the Nigerian National Nuclear Forensic Library. Results showed significant variation in the isotopic concentrations of lead, thorium and uranium across the mines. Isotopic ratios of 238U/235U, 235U/238U and 234U/238U across the sample of 137.881±0.007, 7.253×10-03±2.05×10-04 and 5.540×10-05±4.08×10-07 were found to be consistent with the natural values. The age of natural uranium is comparable to the age of earth. Uranium, lead, and thorium isotopic concentrations and ratios, as well as the age of the samples characterised, provide an isotopic profile that can be used for nuclear forensic application.
Significance:

Given the abundant deposits of natural uranium in Africa and the consequent potential for nuclear insecurity, determining the isotopic profiles and signatures of natural uranium is important for application in nuclear forensics.
Isotopic concentrations of 232Th, 238U, 235U and 234U from the respective sampling sites differed significantly, thereby providing characteristic isotopic profiles.

Published: March 2022

Ficus sur Forssk. (Moraceae) is a medicinal plant species found in Africa and the leaves are used in traditional medicine as a blood builder to boost iron levels for the treatment of anaemia, skin disorders and sexually transmitted diseases. In this study, a phytochemical investigation was conducted on F. sur and the antioxidant properties of the isolates and extracts were evaluated. The major secondary metabolites that were isolated from the fruits and leaves were the triterpenoid (lupeol), sterol (β-sitosterol), phaeophytin (phaeophytin a) and flavonoid (epicatechin). The findings reveal significantly higher (p<0.05) antioxidant activity for the methanol extract of the fruits (IC50 9.06 μg/mL), which may be attributed to the higher phenolic content and presence of epicatechin. The results show the species to be rich in pharmacologically active compounds that are documented to exhibit haematinic effects, stimulate reconstruction and cell proliferation in skin, and inhibit the growth and proliferation of pathogenic agents of sexually transmitted infections. This study therefore validates the ethnomedicinal use of the plant, and its consumption could have a profound influence on nutrition and health, especially amongst indigenous people of Africa.
Significance:

In South Africa, the use of indigenous plants for food and medicine, especially by rural populations, has increased due to availability and accessibility.
This study highlights the benefits of the edible fruits of Ficus suras a nutraceutical.
Ficus suris shown to contain biomolecules with well-known therapeutic value, which lends scientific credence and validity to its ethnomedicinal use.
Émile Prisse D’Avennes - Ippolito Rosellini: Dos propuestas de dibujo sobre el Antiguo Egipto.
Authors: Fdez. de Cañete Rodríguez Nieves 
Published: March 2022

Tras la gran expedición de Napoleón a Egipto, los dibujantes Ippolito Rosellini y Émile Prisse D’Avennes tienen dos propuestas nuevas a través de las que desarrollan su actividad gráfica, ambas marcadas por la personalidad de cada artista, su formación y sus vivencias.
Los dos son conocedores del significado del leguaje jeroglífico, que estudian en profundidad hasta descubrir una nueva poética en las imágenes del arte del antiguo Egipto. Ambos dirigen sus miradas a los mismos referentes artísticos en tumbas y templos, y crean nuevas obras de un estilo ecléctico que vinculan dos momentos muy distantes en el tiempo.
Son capaces, como pocos artistas pueden, de establecer con sus dibujos un diálogo a tres bandas entre el observador, la propia obra y alguna de las imágenes más emblemáticas creadas por los artistas del Egipto faraónico.
Interculturalidad y especialización en traducción de arte contemporáneo
Authors: Rodríguez-Muñoz María Luisa 
Published: March 2022

El crecimiento exponencial del número de museos públicos de arte contemporáneo en España en las tres últimas décadas conlleva un flujo de arte y de material promocional del mismo en el que la traducción intercultural está presente para permitir el acceso del público a exposiciones cuyo material original se edita en otro idioma.
Esta situación representa una oportunidad como nuevo nicho de mercado traductor y como objeto de estudio, al ser la tipología museística una categoría apenas abordada epistemológicamente dentro de los Estudios de Traducción. En aras de dar los primeros pasos en este sentido en una línea de investigación todavía marginal, seleccionamos los textosque pertenecen a la tipología textual "programa de mano" de la exposición Jan Fabre: Estigmas-Acciones y performances 1976-2017, organizada por el Centro Andaluz de Arte Contemporáneo de Sevilla en 2018. Identificamos los retos de traducción, las estrategias que se emplearon y las técnicas aplicadas según el encargo así como las directrices del iniciador. En atención a los resultados, reconocemos las características híbridas (tipología, modalidad, multiculturalidad) de esta práctica traductora que, consideramos, merece un mayor interés por parte de la Academia.
Las Paradojas de la desaparición en México
Authors: Hernández Manrique Adriana 
Published: March 2022

Dejar registro de lo que está por desaparecer es un ejercicio no solo de las buscadoras, colectivo de mujeres que escudriñan en las entrañas de la tierra para hallar a su familiar como consecuencia de la desaparición forzada y sistemática en México cuyas acciones nos revelan que hay lugares, objetos y sujetos de la desaparición. Esta objetivación hecha memoria permite asir lo que escapa, de lo que no se habla, de visibilizar y tomar posición ante una situación que afecta a miles de familias desde antes de que se declarara la guerra al narcotráfico. A esta labor se suman algunos documentalistas que aportan desde la denuncia, desde el retrato de la realidad o desde la narrativa discursiva y que a manera de paradojas responden a un tiempo o espacio específico, los últimos 20 años de guerra de baja intensidad.

Authors: Kochergina A. M. , Kochergin N. A. 
Published: March 2022

Highlights. The review synthesizes the results of clinical studies on the use of sartans. This topic is highly relevant due to the antihypertensive, metabolic and organ-protective effect of sartans, which can positively affect the course of coronary atherosclerosis.Abstract. Angiotensin II receptor blockers (sartans) are widely used to treat cardiovascular diseases. This class of drugs has antihypertensive and metabolic effects and organ-protective capabilities. Currently, sartans are of high interest due to their pleiotropic effect: improved lipid metabolism, antidiabetogenic action, nephroprotection, and, as a result, reduced total cardiovascular risk. The article presents an overview of clinical data on the use of sartans in patients with ischemic heart disease, the mechanisms of organ-protective effects and prospects of using this class of drugs for total cardiovascular risk reduction. The following data sources were used: e-Library, ClinicalTrials.gov, PubMed, trialbulletin.com, smartpatients.com, BioPortfolio.com.

Authors: Olesin A. I. , Konstantinova I. V. 
Published: March 2022

Highlights. The results of primary prevention of atrial fibrillation by using antiarrhythmic drug therapy and modulated kinesitherapy in patients with metabolic syndrome with premature atrial complexes are presented.A significant decrease in the development of the disease was revealed in patients with metabolic syndrome and risk of atrial fibrillation within a year after the examination with the help of pharmacological antiarrhythmic therapy of atrial ectopia and modulated kinesotherapy as primary prevention in comparison with therapy aimed at correcting blood pressure, glucose and blood lipids.Aim. To assess the possibility of using antiarrhythmic drug therapy (DT) and modulated kinesitherapy (MK) in patients with metabolic syndrome (MS) and premature atrial complexes (PAC) as the primary prevention of atrial fibrillation (AF).Methods. 426 MS patients with PAC aged from 58 to 72 years (mean 66.4±0.7 years) were included in the study. All patients had a high probability of developing primary AF within 1 year after the enrollment. Antiarrhythmic DT with class I–III drugs was used as the primary prophylaxis of AF in 149 (34.97%) patients, MK – in 121 (28.40%), the correction of blood pressure, glucose and blood lipids – in 156 (36.63%). All patients were followed up for one year and the end point of observation was the maintenance of sinus rhythm or AF registration.Results. Various clinical forms of AF were recorded in 26.45, 31.54% and 95.51% of patients with MS during primary prevention with the help of pharmacological AAT, UA and correction of its potentially modifiable components (arterial pressure, glucose and blood lipids), respectively, during the year after the examination.Conclusion. The use of both antiarrhythmic DT of I–III classes, and MК as a primary prophylaxis of AF in patients with MS with PAC and the risk of AF development within one year after the first examination made it possible to reduce the frequency of the arrhythmia by the correction of blood pressure, glucose and blood lipids.

Authors: Kaveshnikov V. S. , Serebryakova V. N. , Trubacheva I. A. 
Published: March 2022

Highlights. The leading factor of ineffective arterial hypertension (AH) control in the population taking medications was the number of metabolic risk factors (RF). In addition, in men, the odds of reaching the blood pressure targets were lower if there was a history of kidney disease and bronchitis, and higher, if statins and hypotensive drugs were taken together, respectively. In women, heart rate equal or higher than 75 beats/min and total carotid atherosclerotic plaque thickness were associated with lower and a visit to a physician in the past year - with higher odds of effective hypertension control, respectively.Aim. Analysis of factors associated with reaching blood pressure targets in hypertensive population taking medications.Methods. We examined men and women of 25-64 y.o., randomly drawn from general population, having hypertension and receiving medications. All participants underwent standardized cardiac screening, including a survey on a number of socio-demographic, psychosocial, behavioral variables, traditional and metabolic cardiovascular risk factors, life quality. We measured anthropometric and blood pressure variables, "intima-media" thickness, presence and total thickness of carotid atherosclerotic plaques. Analysis included data from 480 respondents. Parametric and nonparametric statistics were used. To analyze relationships, multivariable logistic regression was used. An error probability <5% was considered statistically significant.Results. After adjustment for age, wealth level, cardio-vascular deseases and the number of antihypertensive drugs, the following factors increased the chances of effective treatment for hypertension in men - statins, positive answer to the question “Do you feel pain or discomfort?” on the EQ5D scale. Lower odds for detecting target blood pressure levels were associated to the count of metabolic syndrome components according to IDF criteria except arterial hypertension (0-4), kidney disease, previous bronchitis, age. A direct association with the effectiveness of treatment for hypertension in women was shown by a visit to the doctor during the past year, and the opposite - the number of metabolic syndrome components, heart rate ≥75 per minute and the total thickness of carotid atherosclerotic plaques, respectively.Conclusion. Lack of hypertension control was associated to metabolic risk factors count, age, kidney disease, heart rate ≥75 per minute, previous bronchitis, lack of visit to a doctor over the past year, as well as total thickness of carotid atherosclerotic plaques. The situation can be improved by deliberately losing weight, taking statins by all people at very high and high risk, and seeing a doctor regularly. It is necessary to further study the factors that hinder achievement of blood pressure targets, as well as methods aimed at the prevention and effective correction of metabolic disorders.

Highlights. For the first time, mapping models of morbidity and mortality from the blood circulation system diseases for assessing the performance of the health protection system in federal districts of the Russian Federation were proposed. The method makes it possible to identify low-quality health systems, and outsider regions, where it is necessary to develop measures in order to identify modifiable and non-modifiable risk factors and improve the performance of health care system both in federal districts and in the Russian Federation as a whole.Aim. To develop mapping models of morbidity and mortality from the blood circulation system diseases (BCSD) and to propose indices for assessing the performance of the health care system in different federal districts of Russia over a 10-year period (from 2010 to 2019).Methods. Reporting forms of federal statistical observation in the field of public health were used.Results. The incidence of BCSD among the population of the Russian Federation has been steadily increasing over the past two decades, increasing 2.047-fold from 2000 to 2019, while the mortality rate of the Russian population decreased 2.073-fold over the same period. Mapping models of morbidity and mortality from BCSD have been developed and indices for assessing the performance of the health protection system in different federal districts of Russia over a 10-year period (from 2010 to 2019) have been proposed.Conclusion. The mapping of low and ultra-low incidence rates of BCSD combined with high and ultra-high mortality rates from BSC among the population of the federal districts indicates low detection rates and low performance of the primary health care system in detecting BSC among the population assigned to receive primary health care according to the territorial principle. The correlation of indicators of general morbidity and mortality from HIPC in relation to health care resources allows timely assessment and finding resources in those areas that contribute to the maximum efficiency of medical organizations at minimum cost.

Highlights. Patient education program developed for patients with prosthetic heart valves, which includes information on the anticoagulant therapy, prevention of prosthetic valve endocarditis, and physical and psychological rehabilitation, helps to improve adherence to treatment and quality of life immediately upon completion of training (6 months). The quality of life and adherence to treatment were higher at 10-year follow-up in patients undergoing full course of training, in inpatient and outpatient settings, compared with patients undergoing training in inpatient setting only.Aim. To evaluate the efficacy of the training program for patients with prosthetic heart valves in improving treatment adherence and quality of life at 10-year follow-up.Methods. Patient education program entitled “School for patients with prosthetic heart valves” was developed and implemented at the Research Institute for Complex Issues of Cardiovascular Diseases (Kemerovo) in 2010. The program provides knowledge and training regarding anticoagulant therapy, prevention of prosthetic valve endocarditis, physical and psychological rehabilitation. The training group consisted of 92 patients who completed a full course of training (6 months). The control group included 56 patients who completed training in inpatient setting only. Long-term efficacy of the developed education program was assessed at 10-year follow-up via evaluation of the indicators of adherence to treatment (questionnaire for determining the integral indicator of adherence to treatment (IIAT)) and the quality of life (using Short-Form 36-item questionnaire (SF-36)).Results. Initially, data analysis showed no statistically significant differences between the groups in the quality of life and adherence to treatment. Six months later the IIAT score in the training group (full course of training) was 9.15±1.16, in controls the score was 6.20±1.05 (р = 0.0001). Highest IIAT scores in the training group remained similar (8.10±1.20 points) at 10-year follow-up, in the control group it was lower - 5.19±1.09 (р = 0.0001). After 6 months, physical component summary score increased by 24% over baseline in controls (р = 0.0001) and by 25% in the training group (р = 0.0001). After 6-month follow-up, there was an improvement in the psychological component summary score by 14.5% (р = 0.0001) in the control group and by 42.8% in the training group (р = 0.0001). 10 years after completion of training, physical component and mental component summary scores were higher in patients undergoing full training course - 8.3% (р = 0.0001) and 14.3% (р = 0.0001), respectively.Conclusion. Patient education program “School for patients with prosthetic heart valves” via full course of training increases levels of adherence to treatment and quality of life mainly due to improvement of psychological component summary score in the early period (6 months) and at 10-year follow-up.

Authors: Krestyaninov O. V. , Badoian A. G. , Naydenov R. A. , Baystrukov V. I. 
Published: March 2022

Highlights. The article analyzes the current evidence base for anticoagulant and antiplatelet therapy in patients with atrial fibrillation undergoing percutaneous coronary interventions, and future perspectives of such therapy.Abstract. A number of patients undergoing percutaneous coronary intervention may require intensification of antithrombotic therapy. These include patients with atrial fibrillation. The difficulty of treatment of this group of patients consists in the achievement of a certain level of hypocoagulation, which will be sufficient for the prevention of acute ischemic events, mainly associated with the implanted coronary stent, but will not lead to the clinically relevant bleeding. Achieving this balance requires a careful and personalized approach to prescribing a variety of combination (antiplatelet and anticoagulant) therapy regimens. The article provides an overview of modern antithrombotic therapy regimens in this group of patients, their evidence base and promising directions for improving such therapy.
