Managing Wind Turbine Generators with a Profit Maximized Approach
Authors: McInnis Dominik , Capezzali Massimiliano
Published: September 2020

In Europe, at least 3 GW installed capacity of wind turbine generators (WTG) will fall out of subsidy schemes every year from 2021 onwards. An estimated 50% of this capacity cannot be replaced with new WTG due to commercial and legal restrictions. The remaining options are either to sell the electricity without subsidies on the wholesale electricity market—a novelty for most WTG, as most are receiving a feed-in tariff—or their dismantlement. Since the electricity market fixes the price at the intersection of demand and short run marginal production costs, WTG might struggle to generate enough revenues to cover their costs. This paper proposes an innovative commercialization strategy for WTG after the end of the feed-in tariff, namely a profit-maximized approach that focuses on synergies between revenues and costs when increasing the curtailments of the WTG. The two key elements of this approach are a more flexible and variable cost structure and a central overall optimization process. The paper proves the potential of this new strategy and highlights the necessity of further research for WTG at the end of their lifetime from a technical and commercial perspective, due to the impact on the initial investment decision and best allocation of subsides.

(1) The studies on the influence of rainfall on slope stability mainly focus on rainfall characteristics and the variation of strength parameters. Few studies pay attention to the micro structure changes of rock mass under long-term rainfall conditions, and the influence of failure mode. (2) Based on nuclear magnetic resonance (NMR) and electron microscopic imaging (Emmi) technology, the micro structure changes and macro deformation characteristics of the schist, under long-term immersion in different liquids are analyzed. (3) After soaking in the deionized water, the uniaxial compression strength of the intact specimen is slightly lower than that of the untreated specimens, but the test process in the elastic compression stage is considerably prolonged, and the failure modes show both shear and slip at the same time. While after soaking in acid solution, the fracture of rock samples with initial cracks can be obviously reduced and healed, which is consistent with the change of micro pore structure. The uniaxial strength and modulus of the intact samples are significantly lower, and only slip failure mode occurred. (4) It shows that water–rock interaction is an important factor influencing the stability of slope besides the external rainfall force, which affects the structural characteristics and mechanical properties of rock.

Published: September 2020

Teacher induction has been an object of interest in teacher education and professional development, mostly as a result of the analysis of the difficulties faced and the coping strategies developed by newly qualified teachers. However, the specific mechanisms to facilitate teachers’ induction when being appointed by schools working under challenging contexts have been less explored. This study aims to explore the potential of a community-based school model named Schools as Learning Communities to induct new teachers and to help them embrace the school’s project. A single case study was conducted in a high-poverty school located in Barcelona (Spain). Data collection included observations and interviews with teachers and the school management team. Findings highlight two main features of the school model that facilitate teacher induction: the dialogic approach to teachers’ professional development and the participation of family and community members in the school, which operates as a pedagogical resource. Furthermore, our results reveal this model as a successful pathway for the new teachers to embrace the school mission and to become agents of transformation who contribute to the project’s sustainability. The study offers lessons on how to support the induction of teachers who join diverse schools serving students living in poverty.

Published: September 2020

Habitat fragmentation affects lichen communities by inducing edge effects, although the dispersal of pollutants by pesticide drift from commercial crops may also provoke alterations in community structure, due to the varying sensitivity of lichen morphotypes to pollutants. In this context, we tested the hypothesis that lichen morphotype richness and diversity, and the percentage area of the trunks covered by different lichen morphotypes are modified significantly at the edges of fragments of Cerrado vegetation inserted within the agricultural matrix. We evaluated habitat fragments representing different Cerrado formations (Cerradão, Cerrado sensu stricto, and seasonal semi-deciduous forest) as well as the Emas National Park, a prominent Cerrado conservation unit. We used Generalized Linear Mixed Models (GLMMs) to test the potential of the models compiled using a mixture of phytosociological and environmental parameters, including the species, the height of the host plant (H), the circumference of its stem at breast height (CBH), total chlorophyll (TC), bark fissuring (BF) and pH, and illuminance (Lum), to explain the observed variation in the lichen morphotype richness and the percentage cover of the trunks by corticolous lichen morphotypes at the center and edge of the fragments. The central areas invariably had a greater diversity of morphotypes in all the fragments. The morphotypes considered highly sensitive to disturbance were not observed in edge areas, confirming a clear edge effect, as well as the influence of pesticide drift from the adjacent farmland matrix, on the structure of the lichen community. At both the edge and center sites, the larger trees (higher CBH) with less fissured bark tended to have the greatest diversity of lichen morphotypes, and more acidic barks had the greatest lichen cover. The models tested indicated that the variable tree species is an important determinant of the observed patterns of lichen morphotype richness and cover, either on its own or in association with pH or CBH + pH. The analyses also indicated that all the variables tested are important in some way for the definition of the percentage cover of the host trunks. The present study contributes to the understanding of the diversity of the corticolous lichen communities in the remaining fragments of Cerrado vegetation and the effects of the agricultural matrix on this community. The lichen may thus play a role as indicators of impact on other species, these organisms may provide important insights for the further investigation of the disturbance caused by the agricultural matrix on the communities of other groups of organisms.

Published: September 2020

The q-Stirling numbers (polynomials) of the second kind have been investigated and applied in a variety of research subjects including, even, the q-analogue of Bernstein polynomials. The (p,q)-Stirling numbers (polynomials) of the second kind have been studied, particularly, in relation to combinatorics. In this paper, we aim to introduce new (p,q)-Stirling polynomials of the second kind which are shown to be fit for the (p,q)-analogue of Bernstein polynomials. We also present some interesting identities involving the (p,q)-binomial coefficients. We further discuss certain vanishing identities associated with the q-and (p,q)-Stirling polynomials of the second kind.

Published: September 2020

Symmetry is an important visual feature for humans and its application in architecture is completely evident. This paper aims to investigate the role of symmetry in the aesthetics judgment of residential building façades and study the pattern of eye movement based on the expertise of subjects in architecture. In order to implement this in the present paper, we have created images in two categories: symmetrical and asymmetrical façade images. The experiment design allows us to investigate the preference of subjects and their reaction time to decide about presented images as well as record their eye movements. It was inferred that the aesthetic experience of a building façade is influenced by the expertise of the subjects. There is a significant difference between experts and non-experts in all conditions, and symmetrical façades are in line with the taste of non-expert subjects. Moreover, the patterns of fixational eye movements indicate that the horizontal or vertical symmetry (mirror symmetry) has a profound influence on the observer’s attention, but there is a difference in the points watched and their fixation duration. Thus, although symmetry may attract the same attention during eye movements on façade images, it does not necessarily lead to the same preference between the expert and non-expert groups.

Published: September 2020

Hepatitis B surface antigen (HBsAg) promotes persistent hepatitis B virus (HBV) infection. It primarily corresponds to small (S) envelope protein secreted as subviral particles. We previously found that genotype D clones expressed less S protein than genotype A clones but showed higher extracellular/intracellular ratio of HBsAg suggesting more efficient secretion. The current study aimed to characterize the underlying mechanism(s) by comparing a subgenotype A2 clone (geno5.4) with a subgenotype D2 clone (geno1.2). Five types of full-length or subgenomic constructs were transfected to Huh7 cells at different dosage. HBsAg was quantified by enzyme linked immunosorbent assay while envelope proteins were detected by Western blot. We found that ratio of extracellular/intracellular HBsAg decreased at increasing amounts of DNA transfected. Conflicting findings from two types of subgenomic construct confirmed stronger secretion inhibitory effect of the genotype D-derived large envelope protein. Chimeric constructs followed by site-directed mutagenesis revealed geno1.2 specific V118/T127 and F161/A168 in the S protein as promoting and inhibitory of HBsAg secretion, respectively. In conclusion, more efficient HBsAg secretion by subgenotype D2 than subgenotype A2 is attributed to lower level of S protein expression in addition to V118 and T127 in S protein, although its F161 and A168 sequences rather reduce HBsAg secretion.

Published: September 2020

In a previous study in influenza-naïve pigs, heterologous prime-boost vaccination with monovalent, adjuvanted whole inactivated vaccines (WIV) based on the European swine influenza A virus (SwIAV) strain, A/swine/Gent/172/2008 (G08), followed by the US SwIAV strain, A/swine/Pennsylvania/A01076777/2010 (PA10), was shown to induce broadly cross-reactive hemagglutination inhibition (HI) antibodies against 12 out of 15 antigenically distinct H3N2 influenza strains. Here, we used the pig model to examine the efficacy of that particular heterologous prime-boost vaccination regimen, in individuals with pre-existing infection-immunity. Pigs were first inoculated intranasally with the human H3N2 strain, A/Nanchang/933/1995. Seven weeks later, they were vaccinated intramuscularly with G08 followed by PA10 or vice versa. We examined serum antibody responses against the hemagglutinin and neuraminidase, and antibody-secreting cell (ASC) responses in peripheral blood, draining lymph nodes, and nasal mucosa (NMC), in ELISPOT assays. Vaccination induced up to 10-fold higher HI antibody titers than in naïve pigs, with broader cross-reactivity, and protection against challenge with an antigenically distant H3N2 strain. It also boosted ASC responses in lymph nodes and NMC. Our results show that intramuscular administration of WIV can lead to enhanced antibody responses and cross-reactivity in pre-immune subjects, and recall of ASC responses in lymph nodes and NMC.

Since its 2013 emergence in the Americas, Chikungunya virus (CHIKV) has posed a serious threat to public health. Early and accurate diagnosis of the disease, though currently lacking in clinics, is integral to enable timely care and epidemiological response. We developed a dual detection system: a CHIKV antigen E1/E2-based enzyme-linked immunosorbent assay (ELISA) and a lateral flow test using high-affinity anti-CHIKV antibodies. The ELISA was validated with 100 PCR-tested acute Chikungunya fever samples from Honduras. The assay had an overall sensitivity and specificity of 51% and 96.67%, respectively, with accuracy reaching 95.45% sensitivity and 92.03% specificity at a cycle threshold (Ct) cutoff of 22. As the Ct value decreased from 35 to 22, the ELISA sensitivity increased. We then developed and validated two lateral flow tests using independent antibody pairs. The sensitivity and specificity reached 100% for both lateral flow tests using 39 samples from Colombia and Honduras at Ct cutoffs of 20 and 27, respectively. For both lateral flow tests, sensitivity decreased as the Ct increased after 27. Because CHIKV E1/E2 are exposed in the virion surfaces in serum during the acute infection phase, these sensitive and specific assays demonstrate opportunities for early detection of this emerging human pathogen.

Published: September 2020

Purpose of review: to provide a prospective on the current mechanisms by which SARS-CoV-2 enters cells and replicates, and its implications for ocular transmission. The literature was analyzed to understand ocular transmission as well as molecular mechanisms by which SARS-CoV-2 enters cells and replicates. Analysis of gene expression profiles from available datasets, published immunohistochemistry, as well as current literature was reviewed, to assess the likelihood that ocular inoculation of SARS-CoV-2 results in systemic infection. Recent findings: The ocular surface and retina have the necessary proteins, Transmembrane Serine Protease 2 (TMPRSS2), CD147, Angiotensin-Converting Enzyme 2 (ACE2) and Cathepsin L (CTSL) necessary to be infected with SARS-CoV-2. In addition to direct ocular infection, virus carried by tears through the nasolacrimal duct to nasal epithelium represent a means of ocular inoculation. Summary: There is evidence that SARS-CoV-2 may either directly infect cells on the ocular surface, or virus can be carried by tears through the nasolacrimal duct to infect the nasal or gastrointestinal epithelium.

A harmonized and integrated approach for monitoring and assessment of contamination, including hydrocarbon exploitation one, is required both by Marine Strategy Framework Directive (MSFD) at EU level and by the Ecosystem Approach (EcAp) program of the Barcelona Convention at Mediterranean level. A broad review of protocols of environmental impact assessment (EIA) procedures, monitoring and decommissioning of offshore platforms adopted by EU and non-EU countries along the Adriatic-Ionian seas was carried out in the framework of the Interreg offshore platforms in Adriatic-Ionian (ADRION) project HarmoNIA (Harmonization and networking for contaminant assessment in the Ionian and Adriatic Seas). The comparison of information provided by six ADRION countries and the application of a harmonized and integrated approach has highlighted specific challenges for managing offshore platform impacts emerged at ADRION level: (i) need of the same legislative level (the Offshore Protocol of Barcelona Convention is not ratified by all countries); (ii) set up of a task force of ADRION experts for discussing critical issues related to impacts of offshore platforms; (iii) harmonization, at the regional level, of EIA procedures, monitoring and decommissioning; (iv) need of an agreed and common list of recommended parameters to monitor in water, sediment and biota for the assessment of impacts due to platform installations and PFW discharges.

Published: September 2020

An important reserve for improving the effectiveness of milk production is the creation of highly productive breeds of cattle by improving them. Families, which are an integral part of the herd structure are essential in this case. Maternal families play a very important role in breeding work to increase the milk productivity. The milk yield, content of protein and fat in milk, udder shape and teats, milk flow rate are actually measured only on females. In the best factory families identify the most promising highly productive cows, which are subsequently used to obtain sires, which often becoming the ancestors of the lines. The main purpose of working with the family is to develop in the offspring of valuable qualities of the ancestor by mating her, her daughters and granddaughters with the best sires belonging to the best line, to obtain high-value off spring. 26 families, which differ on age, level of productivity, quantity of highly productive cows are allocated in the farms in the Voronezh region. According to the development of breeding characteristics of the family to varying degrees deviate from the indicators of the herd. The best results on milk yield have been obtained in the families: Martha 113, Vishnya 1208, Malvina 166, Skoda 8 and Putana 1312, which exceed the average for the herd from 428 to 1019 kg, or from 7,2 to 17,1 %. On the content of fat in milk the superiority of families was revealed: Drofa 752 by 0,23 %, Soroka 2206 by 0,21 %, Manyunya 1013 by 0,19 %, Kukla 1252 by 0,11 %. In terms of protein content in milk the best families were: Spring 8028 by 0,07 %, Boyarka 2118 by 0,04 %, Vishnya 1208 and Soroka 2206 by 0,03 %. Thus, in order to increase the efficiency of milk production in the Voronezh region it is necessary to use selection of maternal families most widely.

The data on live weight, measurements and body indices of young Red deer of Altai-Sayan breed in LLC “Niva” in the Altai Republic have been presented in the article. The purpose of the research was to identify the features of growth and development of young Red deer of Altai-Sayan breed. Two groups of 10 animals in each have been formed. In the 1st group were included males, in the 2nd – females from birth to 18 months of age, which have been kept under the same conditions of feeding and housing. Studies have shown the gain in live weight of young animals in the period from birth to one and a half years. At the end of the experiment males had a live weight of 168,5 kg and surpassed females by 20,4 kg. Data on the average daily, absolute and relative gains in the live weight of young Red deer have been also obtained. The absolute gain in live weight in males from birth to the end of the experiment was 152,0 kg, and in females it was 132,6 kg. The relative gain from birth to the age of 6 months was 136,50 % in males and 141,44 % in females, while from 12 to 18 months it decreased to 26,35 % in males and 30,23 % in females. Comparative analysis of measurements of the two groups has shown that males were taller and larger than female Red deer during the whole period of studies by 3–6 %.

In the creation of new eff ective systems of corporate management in the agricultural sector of the Republic of Belarus at the moment, the latest advanced information and communication technologies come to the fore. Through the active use of these technologies today it is already becoming possible to perceive and subsequently process huge amounts of information, clear structuring and formalization of the received data, providing switching, routing and high-speed exchange of information and data between the control units (objects) and the control system itself. In connection with the global trend of deep digital transformation of all spheres of the economy and clearly defi ned directions of today’s state economic policy and prospects for the gradual transition to full-format digitalization of domestic agriculture, there is a real need to create modern «digital» management systems in agriculture, both at the enterprise level, and at the district (regional) and Republican levels in order to improve the eff ectiveness of enterprises in the industry. To date, one of the promising tasks in the further improvement of the functioning of agricultural organizations is the development of domestic methods for choosing the best options for digitalization of management of agricultural production and processing enterprises of diff erent organizational and legal forms. The general principles of informatization, digitalization of management processes in agricultural enterprises and the principles of building diff erent basic models of information and analytical systems in order to modernize existing management systems in the fi eld of agriculture have been discussed in the article.

Live-animal evaluation of replacement young animals including bull-calves on their own productivity in the breeding of Kazakh White-Headed cattle has of scientific and practical importance. The purpose of the work was a live-animal evaluation of the quality of Kazakh White-Headed bull-calves by their own productivity. Bull-calves of the 3rd group (line of Veteran) in all periods of evaluation on growth can be assigned to the elite-record class. Replacement bull-calves of the 1st group (line of Circled) at all ages for live weight belonged to the elite class. Replacement bull-calves of the 2nd group since 9-month age have been evaluated as a class elite-record. According to the adjusted live weight of replacement bull-calves at the age of 210 and 365 days, the animals of the 3rd group were the best. According to this indicator the bull-calves of the 3rd group at the age of 210 days can be attributed to the 1st class, and at the age of 365 days the elite-record. When evaluating the reproductive capacity of the replacement bull-calves of Kazakh White-Headed breed of different lines the superiority of animals of the 3rd group (line of Veteran) has been found. They have significantly higher scrotum girth than the bull-calves of the 1st group by 7,1 cm or 27,0 % (P ≤ 0,01) and 1,9 cm or 6,0 % (P ≤ 0,05) than the young bulls of the 2nd group. The meat qualities also revealed the superiority of bull-calves of the 3rd group. They had higher indicators for the area of the muscle eye, marbling of meat and a comprehensive assessment of meat qualities. Live-animal evaluation of replacement young animals of beef breeds on their own productivity allows us to quickly increase the number of breeding stock.

Published: September 2020

Breeding work aimed at improving the body type of cattle is of a big importance for improving the efficiency of dairy cattle breeding, since harmoniously built animals are characterized by high milk productivity, long-term economic use and are in significant demand on the market of breeding products. Linear evaluation of the body type of dairy cattle has become very popular and is widely used to assess the appearance of animals in many countries with highly developed cattle breeding (USA, Canada, Netherlands, Germany, etc.). Many researchers use a linear evaluation method for evaluating the body type of cows of different origins obtained both by crossbreeding with improving breeds, and for evaluating sires on the quality of offspring. In the Omsk region scientific research on the use of linear evaluation of the body type of daughters of sires has been carried out in order to further assess their breeding qualities. The purpose of the research was to study the conformation features of first-calf heifers have been obtained from different sires evaluated using the method of linear evaluation of body type. The experimental part of the work has been carried out in breeding farms in the Omsk region: JSC “Razdolnoe” of the Russian-Polyansky district and JSC “Azovskoye” of the Azov district. It has been established that the sire directly determines the conformation features of the daughters, which in turn affects their milk productivity, health and ease of calving.
TEXT OF POLICY IN THE BACKGROUND OF CIVILIZATIONAL CONTEXTS AND SUBTEXTS AS A MISSING ELEMENT OF EDUCATIONAL DISCOURSE
Authors: Samchuk Zoreslav
Published: September 2020

Politics feels the steady influence of the civilization factor first of all and mainly because for various reasons the way of its existence prevents the careful selection of optimal articulation, argumentation and rhetorical approaches; instead of this, the civilization factor works not so much within the limits of specific and historical priorities, as in a much longer retrospective and perspective.
Unlike politics, for civilization modernity is a minor episode, which becomes meaningful only in the context of some historical continuity and prospects for the future. At the expense of the closest possible association links with the civilization factor, politics tries to legitimize and raise its institutional status and ensure a respectable image. It tries to prove that it also works on the principles of historical continuity, and her argumentatively vulnerable memoranda are not without prospects for the future.

Amaç: Covid 19 pandemisi sırasında dünyanın bazı bölgelerindeki karantina uygulamaları, toplumsal izolasyon ve sosyal mesafe gibi önlemler hayatımızdaki pek çok tercihimizi etkilediği gibi gebelerin bu dönemde takip ve doğum için hastane seçimlerini de etkileyebilir. Çalışmamızda; pandemi dönemi ile bir önceki yıl aynı zaman aralığı karşılaştırılarak bu değişimin belirlenmesi amaçlanmıştır
Metod: Çalışmamız retrospektif ve kesitsel olarak bölgemizde pandemi hastanesi olarak seçilen Karabük Üniversitesi Eğitim ve Araştırma Hastanesinde yapıldı. Çalışmamıza; Türkiye’de ilk vakanın görüldüğü ve önlemlerin hızla alındığı tarih olan 11 Mart ile Türkiye’deki yeni vakaların plato çizmeye başladığı 25 nisan 2020 tarihlari arasındaki Karabük Eğitim Araştırma Hastanesinde doğum yapan tüm gebeler (pandemi grubu) ile doğumun mevsimsel farklılıklarını ortadan kaldırmak amaçlı bir yıl önceki aynı dönemde yani 11 mart-25 Nisan 2019 tarihleri arasında hastanemizde doğum yapan gebeler (kontrol grubu) alındı. Hastaların ortalama yaşları, doğum şekilleri, doğum yaptıkları gebelik haftası ve doğum tarihleri ile ilgili bilgiler için hastane istatistik verileri kullanıldı.
Bulgular: Pandemi dönemindeki doğum sayıları daha düşüktü (p=0.000). Normal vajinal doğum sayısı pandemi döneminde azalmıştı (p=0.000). Primer sezaryen oranları ve eski sezaryen oranları arasında fark yoktu. (p=0.34, p=0.45). Her iki gruptaki gebelerin yaş ortalamaları benzerdi (p=0.32), gebelik haftaları benzerdi (p=0,46).
Sonuç: Pandemi döneminde, 3. Basamak üniversite hastanesi kadın hastalıkları ve doğum bölümünde düzenli takibe gelen gebelerin doğum sayılarında azalma mevcuttu. Bu azalmanın nedeni hastaların; covid 19 ile enfekte hastaların olmadığı diğer özel sağlık kuruluşunu tercih etmeleridir. Çalışmamızın benzer olaylarda hastaların gösterdiği sağlık tesislerinin seçimi ve doğum şekillerinin değişimi açısından ileriki çalışmalar için referans olabileceği görülmektedir.

Для вивчення специфіки внутрішньої картини хвороби у жінок, хворих на депресивні розлади різного генезу й вираженості психосоціальної дезадаптації, для визначення, в подальшому, таргетних мішеней диференційованої психосоціальної реабілітації даного контингенту пацієнтів, було обстежено 252 жінки, яким було встановлено діагноз депресивного розладу. У дослідження були включені 94 особи з депресивним розладом психогенного генезу (пролонгована депресивна реакція, обумовлена розладом адаптації), 83 жінки з ендогенною депресією (депресивний епізод; рекурентно депресивний розлад; біполярний афективний розлад, поточний епізод депресії) і 75 пацієнток з депресивним розладом органічної генези (органічні афективні розлади). Дослідження проводилося з використанням клініко-психопатологічного та психодіагностичного методів. В результаті дослідження у хворих з різним генезом депресії та наявністю або відсутністю ознак психосоціальної дезадаптації, виявлено різні варіанти і типи внутрішньої картини хвороби. Встановлено, що за умови наявності ознак психосоціальної дезадаптації у жінок наявне більш дезадаптивне ставлення до хвороби, у порівнянні з пацієнтками без дезадаптивних проявів, незалежно від генезу депресивного розладу. Ці закономірності повинні враховуватися при розробці лікувально-реабілітаційних та профілактичних заходів для хворих на депресію

Nowadays, we have been a steady increase in injuries as the social conditions of life and have changed. Statistically found that 54.0 % of people of car accidents have injuries to the head and neck. According to the literature, mortality in patients with neck injury which is complicating by pyoinflammatory persists up to 30.0-76.0 %. The management of neck trauma can be challenging and sometimes overwhelming, as this anatomical region contains many vital structures. These structures may pose a diagnostic and therapeutic dilemma. Our research based on the results of diagnosis and treatment of 124 patients with a purulent mediastinitis, complicating traumatic injuries of the neck organs. Among these men – 92 (74.2 %), women – 32 (25.8 %). The results of treatment depend on timely diagnosis, hospitalization in a specialized compartment and conducting active surgical tactics

В статье представлено исследование сыворотки крови больных ремиттирующе-рецидивирующим рассеянным склерозом (РС) на стадии обострения и больных с болезнью Вильсона-Коновалова (БВК) с неврологическими проявлениями. Было обследовано 24 больных с ремиттирующе-рецидивирующим рассеянным склерозом на стадии обострения и 9 больных с болезнью Вильсона-Коновалова. Контрольную группу составили 30 человек без неврологических заболеваний. В группе больных РС на стадии обострения концентрация нейротрофического фактора BDNF была выше по сравнению с группой больных БВК. Полученные данные свидетельствуют о том, что BDNF может служить показателем развития дегенеративного сценария течения ремиттирующе-рецидивирующего рассеянного склероза. Определение концентрации BDNF может быть использовано в качестве мониторинга активности атрофического процесса и эффективности лечебно-реабилитационных мероприятий

Objetivos: Describir los hallazgos hematológicos en donantes preseleccionados a plaquetoferesis sanguínea en el Hospital Nacional Edgardo Rebagliati Martins (HNERM) de Lima, Perú. Materiales y métodos: Estudio de tipo observacional, descriptivo y transversal, realizado entre Mayo-Julio 2019. Se incluyeron hemogramas de donantes que resultaron ¨Aptos¨ a la entrevista médica, con resultado ¨Negativo¨ a marcadores serológicos y que fueron diferidos en donar por presentar alteración hematológica. Los datos fueron recolectados del sistema informático del servicio de medicina transfusional del HNERM. Se utilizó estadística descriptiva y analítica (U de Mann Whitney y Chi-cuadrado de Pearson) considerándose un valor p<0,05 como significativo. Resultados: Se analizaron los hemogramas de 330 donantes preseleccionados diferidos, entre los cuales el recuento absoluto de eosinófilos (14,2%), el hematocrito (14,2%) y el recuento de plaquetas (33,9%) fueron las de mayor presencia. Asimismo, en las observaciones la fórmula leucocitaria invertida (20,6%) fue la más frecuente. Además, se observó diferencia estadística significativa (p<0,05) entre la hemoglobina, el hematocrito, la hemoglobina corpuscular media (HCM) y la fórmula leucocitaria invertida de acuerdo al sexo del donante. Conclusiones: La alteración hematológica observada más frecuentemente en esta población fue la plaquetopenia. Además, algunos parámetros de la serie roja y la distribución leucocitaria en el hemograma estuvieron asociados con el género del donante.

Los linfomas son el conjunto de enfermedades neoplásicas de los linfocitos. El diagnóstico se fundamenta en la anamnesis, examen físico, biopsia ganglionar y estudios imagenológicos que permiten valorar la enfermedad para su estadiación y tratamiento. Objetivo: Caracterizar a partir de indicadores clínico-histo-imagenológico en casos con linfomas de localización mediastinal atendidos en el Instituto Nacional de Oncología y Radiobiología de Septiembre de 2017 a Diciembre de 2019. Materiales y métodos: Se realizó un estudio preliminar, descriptivo, prospectivo en una población de 167 casos y una muestra de 43 pacientes con linfomas de localización mediastinal. Se estudiaron las variables: sexo, edad, índice de masa corporal, síntomas y signos, tipo de tumor, subtipo histológico, estadiación por criterios de Ann-Arbor, tamaño ganglionar y localización mediastinal. Resultados: El pico de incidencia se observó entre los 25-35 años. La mayor cantidad de casos presentaron sobrepeso (n=10; 23,3%). Predominaron los Linfomas de Hodgkin (n=31; 71,8%) subtipo Esclerosis Nodular (n=22; 51,2%) con estadio IA (LH=14; 32,6%). El tamaño promedio de los ganglios fue de 25,1±17,3 mm. En todos los niveles de la anatomía mediastínica se observaron lesiones ganglionares, a predominio del mediastino superior. Otras características predominantes observadas por TC incluyeron ganglios hipodensos homogéneos (n=34; 79,07%), realce postcontraste con captación homogénea (n=24; 55,81), invasión de estructuras vecinas (n=18; 41,8%) y densidades entre 32-108 UH. Conclusiones: En la valoración de los indicadores imagenológicos por tomografía computarizada contrastada se detectan cambios morfológicos, al tomar como criterio fundamental la afectación ganglionar y el tamaño de las adenopatías en el diagnóstico, estadiamiento y reevaluación de casos con linfomas.
