Neuroendocrine Tumors of the Pancreas
Authors: Morgan Katherine A. 
Published: December 2021

Pancreatic neuroendocrine tumors (PNETs) comprise a diverse, heterogeneous group of tumours that range in presentation and biologic behavior, including small, asymptomatic, incidentally discovered, nonfunctional neoplasms, functional tumors (both localizable and unlocalizable) with associated clinical syndromes, and diffuse metastatic disease. Based on its functional status, the malignancy of a PNET can vary, from the benign (insulinoma) to that which is commonly malignant more than 50% of the time (gastrinoma, somatostatinoma). According to a recent study, PNETs appear to be increasing in incidence or at least in clinical detection; currently the disorder accounts for 1 to 2% of pancreatic tumors and with a reported clinical incidence of one to five cases per million persons annually in the United States. Nonfunctional PNETs make up the majority of cases, and comprise 2% of all pancreatic malignancies. Treatment has been primarily done through surgical management, particularly via resection. However, medical management has played a more increased role for patients where the disease is advanced, encompassing biotherapy, chemotherapy, and targeted therapies such as peptide receptor radionuclide therapy (PRRT). For nonfunctional PNETs—insulinomas, gastrinomas, glucagonomas, somatostatinomas, and VIPomas—the epidemiology, biology of disease, clinical presentation and diagnosis, localization of tumor, operative management considerations, surgical management of primary tumor, and prognosis and outcomes of each are discussed.

Kald krig i kommentarfeltet? Historien om Frode Berg på russisk internett
Authors: Kalsaas Johanne 
Published: December 2021

The article explores how the Russo–Norwegian espionage debacle involving former border inspector Frode Berg was collectively and fragmentarily narrated by Russian online commenters. Through a digital ethnographic case study of user-driven segments on the Russian-language Internet (RuNet) – notably Live Journal and RT comment sections – this article shows how online narratives about the case involved participatory production by heterogeneous, polyphonous constellations of users. Analysing Russian online comments as network narratives, the article examines how Norway (as well as NATO and the West more broadly) has been construed on RuNet, where propaganda is ubiquitous, and where trolls, bots, vatniki and ‘everyone else’ continuously clash. Commenters’ discussions of the Berg case reflect Kremlin-controlled narratives of Norway as an ambiguous actor associated with a high degree of ambivalence, but network narratives also reveal tensions, inconsistencies and contestation of the Russian antagonist discourse on Norway. More broadly, the study highlights how interactive digital narrative can serve to expand our understanding not only of Russia’s relationship with Norway, but also of Russian informational activities as such.
Encruzilhadas e extremidades da língua:
Authors: Macêdo Larissa , Mello Christine 
Published: December 2021

Este artigo busca pensar a língua de forma descentralizada, como lugar desconstrutor de linguagens e da colonialidade, a partir de tensionamentos entre a arte contemporânea, as linguagens digitais e as redes sociais no contexto da cultura do compartilhamento da década de 2010 a 2020. Para isso, propõe articulações críticas entre a abordagem das extremidades, de Christine Mello, o conceito de encruzilhada, de Leda Maria Martins, e a perspectiva de margem, de bell hooks, dentre outros autores. O objetivo é compreender a presença de biarritzzz, artista brasileira (Fortaleza, CE, 1994), por meio da leitura de alguns trabalhos no formato GIF, compartilhados por ela em seu perfil no Instagram. Em @biarritizzz, buscaremos observar certas extremidades com as quais a língua, a arte contemporânea e as redes sociais ressignificam a atualidade.

Virittäjän 125. vuosikerta huipentuu tähän numeroon. Niinpä onkin luontevaa luoda katse taaksepäin ja tehdä sukelluksia muutamiin lehdessä tarkasteltuihin aihepiireihin ja tutkimusaloihin.
Jos haluaa saada yleiskuvan eri tutkimusalojen käsittelystä eri vuosikymmenillä, kannattaa aloittaa Riku Erkkilän ja Teemu Palkin havaintokirjoituksesta. Jussi Ylikosken artikkeli muistuttaa aiheellisesti, että Virittäjä ei ole vain fennistinen aikakauslehti, vaan se on perustamisestaan asti ollut myös fennougristiikan keskeinen julkaisukanava. Tätä kuvaa vahvistaa osaltaan Sampsa Holopaisen, Santeri Junttilan ja Petri Kallion syväluotaus siihen, miten lainasanatutkimuksen erilaiset kaudet näkyvät Virittäjän lehdillä. Kolmannen ikkunan lehden historiaan avaa Terhi Ainialan ja Paula Sjöblomin artikkeli, jossa tarkastellaan Virittäjässä esiteltyä nimistöntutkimusta metodologisesta näkökulmasta.
Artikkelien antia täydentävät havaintokirjoitukset. Minna Jaakola ja Johanna Komppa selvittävät, millaiset julkaisut on nimetty Virittäjässä perusteoksiksi; huomio on erityisesti kirja-arvioissa. Jyrki Kalliokoski puolestaan esittelee kaunokirjallisuuden kielen tutkimusta Virittäjän eri vuosikymmenillä. Viimeinen havaintokirjoitus ei tarkastele lehden historiaa, vaan linkittyy juhlavuoteen ja -numeroon sitä kautta, että se on viimevuotisen opiskelijoille suunnatun kirjoituskilpailun satoa. Milla Juhosen tutkimuskohteena on Mika Waltarin Komisario Palmu -kirjojen nimistö.
Vaikka Virittäjän historiaa valottavien kirjoitusten näkökulmat ovat monipuolisia, on helppo huomata myös isoja aukkoja. Olisi kiehtovaa tarkastella esimerkiksi sitä, miten puhutun kielen tutkimus tai vaikkapa tekstintutkimus ovat vuosikymmenten saatossa muuttaneet muotoaan. Entä miten erilaiset kielioppinäkemykset ja paradigmojen muutokset ovat nähtävissä julkaisussa? Tutkittavaa riittää siis seuraavaankin merkkivuoteen.
Virittäjän juhlinta ei pääty tähän vuosikertaan vaan jatkuu ensi vuonna etenkin Virittäjä 125 -verkkosivuston muodossa. Ensi vuoden toiminnan mahdollistaa osaltaan Jenny ja Antti Wihurin rahasto, jota kiitämme juhlavuoden apurahasta.
Tämä suunvuoro on viimeiseni Virittäjän päätoimittajan roolissa. Kauteni on ollut lyhyt verrattuna pitkäaikaisimpiin edeltäjiini, kuten Lauri Hakuliseen ja E. A. Tunkeloon, jotka hoitivat tehtävää vähintään 20 vuotta. Nämä kuusi vuotta (joista ensimmäinen varapäätoimittajana) ovat olleet antoisia ja avartavia, eivät kuitenkaan aina helppoja. Kiitän lämpimästi kaikkia yhteistyökumppaneitani ja työtovereitani: kirjoittajia, toimitusneuvoston jäseniä ja muita arvioijia, Kotikielen Seuran johtokuntaa ja erityisesti kaikkia toimituksen jäseniä, joiden kanssa olen saanut tehdä sujuvaa yhteistyötä. Toivotan onnea ja menestystä seuraajalleni Laura Visapäälle, joka on laskujeni mukaan Virittäjän 21. päätoimittaja.

SAFETY AND QUALITY OF INTRAVENOUS LIPIDS FOR NEWBORNS: EFFECTS ON CRITICAL DISEASES AND METABOLIC DISORDERS (PART II)
Authors: Anikin I. , Snisar V. 
Published: December 2021

Premature birth and its complications cause stress in newborns, which restrains their physical growth for several weeks after birth and is associated with chronic morbidity and neurological disability in the future. Preterm infants face such difficulties as respiratory distress, cardiovascular disease, gastrointestinal dysfunction and very low birth weight. Most complications in newborns are associated with oxidative stress that develops during the early period of growth. The formation of free radicals entails oxidative damage to many organs and systems of the body and is the main factor responsible for the development of typical diseases of preterm infants, such as bronchopulmonary dysplasia, patent ductus arteriosus, retinopathy of prematurity, necrotizing enterocolitis, intraventricular hemorrhage, and respiratory distress syndrome.
Premature infants depend on adequate early parenteral nutrition, which not only guarantees they will survive but also ensures positive health outcomes later in life. Early use of intravenous lipids helps to prevent essential fatty acid deficiencies, provides energy and substrates for cell membrane synthesis, which are important for the growth and development of infants with very low and extremely low birth weight. This publication represents data on the effect of intravenous lipids on critical conditions and metabolic disorders in newborns. Literature sources are analyzed and the existing evidence of the possible influence of lipid emulsions on critical diseases in newborns is presented: intraventricular hemorrhage; necrotizing enterocolitis, patent ductus arteriosus and thrombocytopenia; glucose metabolism (hypo- and hyperglycemia); hyperbilirubinemia and chronic liver damage. The literature review is aimed at finding optimal strategies for the use of lipid emulsions in intensive care of newborns to improve the quality of care for premature infants. The purpose of this work is to analyze the results of published studies and systematize data on the feasibility and safety of lipid emulsions used in newborns with critical diseases of the perinatal period.
FEATURES OF CARDIOVASCULAR ADAPTATION IN NEWBORNS BORN FROM MOTHERS WITH METABOLIC SYNDROME

Published: December 2021

Introduction. Overweight and obesity, the manifestations of metabolic syndrome during pregnancy, and their consequences are huge public health challenges. The effect of a mother`s metabolic syndrome on the condition of a newborn is insufficiently studied.
The aim is to establish the features of cardiovascular adaptation of premature infants born from mothers with metabolic syndrome, and to identify metabolic maternal and infant risk factors that are mostly associated with high blood pressure and cardiopathy.
Material and methods. A cohort prospective study was conducted, which included 97 premature newborns who were treated in the intensive care unit. Two groups were formed: the main group included premature infants born from mothers with metabolic syndrome (n = 40), and the comparison group included premature infants born from mothers without metabolic syndrome (n = 57).
Results. Infants born from mothers with metabolic syndrome had significantly higher blood pressure than normal according to the gestational age of a child (45.5 ± 0.13 vs. 42.56 ± 0.13 mm Hg, p <0.001). High blood pressure in infants was significantly associated with maternal lipid metabolism disorders (OR 30.9) and hypertension (OR 4.8). The study found a significant positive relationship between blood pressure and overweight in an infant (Coef. 0.168), and a significant negative relationship with glucose level in blood serum (Coef. -0.037). It was found that cardiomyopathy is significantly more common in children of the main group (p = 0.010), its development is associated with the presence of diabetes in a mother (OR 7.57). The more components of the metabolic syndrome a woman has, the more likely a child is to have cardiomyopathy. The risk of developing cardiomyopathy is significantly influenced by a number of risk factors on the part of a newborn.
Conclusions: High blood pressure in premature infants is significantly associated with a complex of components of the metabolic syndrome in mothers (hypertension and / or preeclampsia, obesity, diabetes and disorders of lipid metabolism in a mother (OR 14.71, p <0.001)). The role of carbohydrate metabolism disorders in a child in the development of high blood pressure has been demonstrated. It is proved that the development of cardiopathy in newborns is associated with risk factors from both a child and a mother, which indicates a complex effect of metabolic factors on the adaptation of the cardiovascular system.
Comparison of Gradient-Based Edge Detectors Applied on Mammograms
Authors: Moroz-Dubenco C. 
Published: December 2021

Breast cancer is one of the most common types of cancer amongst women, but it is also one of the most frequently cured cancers. Because of this, early detection is crucial, and this can be done through mammography screening. With the increasing need of an automated interpretation system, a lot of methods have been proposed so far and, regardless of the algorithms, they all share a step: pre-processing. That is, identifying the image orientation, detecting the breast and eliminating irrelevant parts.
This paper aims to describe, analyze, compare and evaluate six of the most commonly used edge detection operators: Sobel, Roberts Cross, Prewitt, Farid and Simoncelli, Scharr and Canny. We detail the algorithms, their implementations and the metrics used for evaluation and continue by comparing the operators both visually and numerically, finally concluding that Canny best suit our needs.
Selección de modelos hipsométricos locales y generales para Eucalyptus globulus en macizos del sudeste de la provincia de Buenos Aires, Argentina

Published: December 2021

El objetivo de este trabajo fue seleccionar modelos hipsométricos locales y generales para estimar alturas totales (h; m) de Eucalyptus globulus Labill. en macizos del sudeste de Buenos Aires, Argentina. Del conjunto inicial de 53 modelos candidatos, fueron seleccionados 14 para su validación. Se emplearon 236 árboles apeados para el ajuste y la validación cruzada, efectuando posteriormente una validación independiente con 743 árboles, cuyos datos de altura y diámetro a la altura del pecho (d) se obtuvieron en un inventario no destructivo. Las ecuaciones locales tuvieron en general la menor calidad de ajuste y precisión. Los mejores resultados con ecuaciones generales se lograron incorporando variables de rodal como el diámetro medio cuadrático (dg; cm), el número de individuos vivos por hectárea (N) y la altura dominante (H0; m). La inclusión de otras variables como la edad, el índice de sitio, el diámetro máximo y el área basal no mejoraron los indicadores de ajuste y validación. Se seleccionaron los tres modelos que obtuvieron los mejores estadísticos de ajuste y validación (Coeficiente de determinación ajustado R2aj.>0,69; Eficiencia del modelo>0,76; Raíz del error medio cuadrático<3,3 m), buscando un compromiso entre calidad de predicción por un lado y sencillez de uso por otro. Los modelos fueron recalibrados para toda la muestra (n=979), y estuvieron dirigidos a cubrir un amplio rango de usos posibles. Para aquellas aplicaciones expeditivas se seleccionó el modelo local 1, de tipo exponencial. Para usuarios que busquen estimaciones de altura más precisas sin medir ninguna altura del rodal, se seleccionó el modelo general 4, basado en d, dg y N, en tanto que para aquellas aplicaciones que requieran una mayor precisión se seleccionó el modelo general 7, que utiliza d y H0 como variables predictoras. El uso combinado de los modelos 1, 4 y 7 permite estimar h en un rango de tamaños de árbol de 2 a 55 cm de d con un error relativo porcentual inferior a ±10%.
Enyesado de suelos sódicos: modificación de sus propiedades químicas, físicas y biológicas

Published: December 2021

Los suelos sódicos ocupan una extensa proporción de la Depresión del Salado. El sodio aumenta el pH y provoca la dispersión de las arcillas generando modificaciones en la estructura de los suelos que perjudican el crecimiento de los cultivos al reducir su porosidad y su infiltración. La aplicación de yeso puede mejorar las características de los suelos sódicos. Se realizó un ensayo en el que se aplicaron tres dosis de yeso: A) 0 kg/ha (testigo); B) 100 kg/ha (en la línea de siembra) y C) 12000 kg/ha (en cobertura total). Se replicó el ensayo usando dos cultivos: Festuca (Festuca arundinacea Schreb.) y Agropiro (Thynopirum ponticum Barkworth & D.R.Dewey). En los distintos tratamientos se midieron propiedades químicas (pH, conductividad eléctrica, porcentaje de sodio intercambiable (PSI) y carbono orgánico), físicas (resistencia a la penetración, resistencia al corte, densidad aparente e infiltración) y biológicas (porcentaje de implantación y productividad primaria neta). El yeso redujo el pH, aumentó la conductividad eléctrica y redujo el PSI. Además, no modificó la resistencia al corte del suelo, pero sí aumentó su capacidad portante en una situación de elevada humedad y mejoró su conductividad hidráulica. Si bien todos estos cambios mejoraron el porcentaje de implantación de ambos cultivos no se modificó la producción de materia seca.
El rol de tutores en la Facultad de Psicología (UNLP) antes y durante la pandemia
