Abstract

Introduction. Alpine skiing is one of the most dangerous winter sports that entails a high number of injuries, most commonly affecting the knee. Kinesiophobia is a condition in which an individual experiences fear of physical movement and activity as a result of feeling susceptible to injuries or recurrent injuries. The objective was to examine the level of kinesiophobia in skiers who have sustained knee injuries.

Material and methods. The sample consisted of 22 female and 11 male professional skiers, with the average age of 24 ± 7.391 years. For the purpose of the assessment, the Tampa scale for kinesiophobia (TSK) was employed.

Results. The number of knee injuries in skiers totals at least 1 and 11 at most, on average 2.45, most commonly involving the anterior cruciate ligament and meniscus. There were no significant differences between the left and the right knee or bilateral injuries. The average score in the TSK totals 36 points, which is close to the critical threshold of 37 points. 36% of the participants possess a high level of kinesiophobia. With respect to the general level of kinesiophobia, no significant differences were found in relation to gender, with regard to the number of surgeries or whether one or both knees were affected by injuries. Older skiers have also been found to have significantly lower fear of recurrent injuries.

Conclusions. The number of knee injuries in skiing is high and aggravating, in such a way that almost one third of skiers that have sustained knee injuries experience a critical level of kinesiophobia, and that requires intervention. During rehabilitation, psychological support should also be provided to athletes in order to prevent or reduce kinesiophobia and thus prevent recurrent or new injuries.

Abstract

Background
The aim of the study was to derive and compare metabolic parameters relating to benign and malignant pulmonary nodules using dynamic 2-deoxy-2-[fluorine-18]fluoro-D-glucose (18F-FDG) PET/CT, and nodule perfusion parameters derived through perfusion computed tomography (CT).

Patients and methods
Twenty patients with 21 pulmonary nodules incidentally detected on CT underwent a dynamic 18F-FDG PET/CT and a perfusion CT. The maximum standardized uptake value (SUVmax) was measured on conventional 18F-FDG PET/CT images. The influx constant (Ki
) was calculated from the dynamic 18F-FDG PET/CT data using Patlak model. Arterial flow (AF) using the maximum slope model and blood volume (BV) using the Patlak plot method for each nodule were calculated from the perfusion CT data. All nodules were characterized as malignant or benign based on histopathology or 2 year follow up CT. All parameters were statistically compared between the two groups using the nonparametric Mann-Whitney test.

Results
Twelve malignant and 9 benign lung nodules were analysed (median size 20.1 mm, 9–29 mm) in 21 patients (male/female = 11/9; mean age ± SD: 65.3 ± 7.4; age range: 50–76 years). The average SUVmax values ± SD of the benign and malignant nodules were 2.2 ± 1.7 vs. 7.0 ± 4.5, respectively (p = 0.0148). Average Ki
values in benign and malignant nodules were 0.0057 ± 0.0071 and 0.0230 ± 0.0155 min-1, respectively (p = 0.0311). Average BV for the benign and malignant nodules were 11.6857 ± 6.7347 and 28.3400 ± 15.9672 ml/100 ml, respectively (p = 0.0250). Average AF for the benign and malignant nodules were 74.4571 ± 89.0321 and 89.200 ± 49.8883 ml/100g/min, respectively (p = 0.1613).

Conclusions
Dynamic 18F-FDG PET/CT and perfusion CT derived blood volume had similar capability to differentiate benign from malignant lung nodules.

Abstract

Background
Robotic resections represent a novel approach to treatment of colorectal cancer. The aim of our study was to critically assess the implementation of robotic colorectal surgical program at our institution and to compare it to the established laparoscopically assisted surgery.

Patients and methods
A retrospective case-control study was designed to compare outcomes of consecutively operated patients who underwent elective laparoscopic or robotic colorectal resections at a tertiary academic centre from 2019 to 2020. The associations between patient characteristics, type of operation, operation duration, conversions, duration of hospitalization, complications and number of harvested lymph nodes were assessed by using univariate logistic regression analysis.

Results
A total of 83 operations met inclusion criteria, 46 robotic and 37 laparoscopic resections, respectively. The groups were comparable regarding the patient and operative characteristics. The operative time was longer in the robotic group (p < 0.001), with fewer conversions to open surgery (p = 0.004), with less patients in need of transfusions (p = 0.004) and lower reoperation rate (p = 0.026). There was no significant difference between the length of stay (p = 0.17), the number of harvested lymph nodes (p = 0.24) and the overall complications (p = 0.58).

Conclusions
The short-term results of robotic colorectal resections were comparable to the laparoscopically assisted operations with fewer conversions to open surgery, fewer blood transfusions and lower reoperation rate in the robotic group.

Abstract

Background
The aim of the study was to evaluate pretreatment inflammatory markers as prognostic factors in patients with unresectable uveal melanoma liver metastases treated with transarterial hepatic chemoperfusion.

Patients and methods
54 patients (44% male, median age: 61 years) were retrospectively assessed. A median of 3 (range: 1–11) treatment sessions were performed with melphalan (92%) or fotemustin (8%). Inflammatory indices were calculated as follows: neutrophils/nl to lymphocytes/nl ratio (NLR), systemic immune-inflammation index ([platelets/nl × neutrophils/nl]/[lymphocytes/nl]; SII), and platelets/nl to lymphocytes/nl ratio (PLR). The cut-off for dichotomization purposes was set at the median (inflammatory indices, hepatic tumor burden) or the upper level of normal. Kaplan Meier analysis was performed for median overall survival (OS) in months, and Cox proportional hazard model for uni(UVA) and multivariate (MVA) hazard ratio (HR, 95%CI) analyses were performed.

Results
Median OS of the study cohort was 7.7 (6.3–10.9) months. In UVA OS was prolonged for low C reactive protein (CRP) (13.5 vs. 5.2; p = 0.0005), low SII (10.8 vs. 5.6; p = 0.0005), low NLR (11.1 vs. 6.3; p = 0.0045), low aspartate aminotransferase (AST) (11.5 vs. 5.6; p = 0.015), alanine aminotransferases (ALT) (11.5 vs. 5.6; p = 0.01), and tumor burden ≦ 50% (8.2 vs. 4.8; p = 0.007). MVA confirmed low CRP (HR: 0.29, 0.11–0.7; p = 0.005), low SII (HR: 0.19, 0.11–0.7; p = 0.008), and low ALT (HR: 0.13, 0.02–0.63; p = 0.011) as independent predictors for prolonged OS. Patients with ≦ 1, 2, 3 elevated significant MVA-factors survived a median of 14.9, 7.7, and 3.9 months, respectively (p = 0.0001).

Conclusions
Pretreatment inflammatory markers (CRP, SII) and AST were independent prognostic survival markers in patients with uveal melanoma liver metastases treated with transarterial hepatic chemoperfusion. A combination of factors may help to identify patients potentially benefitting from treatment.

Abstract
Introduction/Goal: The goal of this paper is to analyze the hospitalization patterns of MS patients in the central and western Serbiain terms of hospitalization days, average length of inpatient stay, hospitalization rate, rehospitalizationpractices and treatment outcomes. Method: The research is designed as a retrospective descriptive epidemiological study. The study uses hospitalization reports from the Clinical Center of Kragujevacfor the time period ranging from January, 2007–December, 2014. Results: The study has revealed that during the given time period, 1.109 MS patients were hospitalized (745 female and 364 male). Women were significantly more numerous (67.2%) (p<0.05).The average rate of hospitalization equaled 70.5 days per 100,000 citizens and was higher with women (94.8 per 100,000) than with men (45.4 per 100,000). The study has revealed a declining trend in hospitalization rates, inpatient days and average length of hospitalization. The number of standard inpatient days decreased while the number of hospitalizations in the day hospital increased (r =- 0,905, p=0.002). In terms of age, the study has revealed that the number of hospitalizations decreased and hospitalization length increased with age (p<0.05).There was a statistically significant inverse correlation between age and rehospitalization (r=-0.138, p=0.000).In respect to treatment outcomes, in 93% there was an improvement of the condition. Conclusion: The obtained results indicate that there is a need for establishing a register which could enable long-term monitoring of patients with MS which could eventually provide certain insights into the different aspects of the illness.
Guillain-Barre syndrome associated with COVID-19 infection
Authors: Ildem Garanti , Engez Duygu , Bektas Hesna , Kursun Oguzhan 
Published: May 2021

Background:
Coronavirus disease 2019 (COVID-19) typically causes breathing issues that can range from flu symptoms to extreme pneumonia, but it can also impair extra respiratory systems and cause multisystemic failure, including neurological complications.

Case Presentation:
A 55-year-old male with acute progressive symmetrical ascending quadriparesis complaints was admitted to the hospital. Twelve days prior to hospitalization, the patient with taste disruption, myalgia, fever, and polymerase chain reaction with reverse transcription was confirmed to have been positive for COVID-19 infection. The neurophysiological findings were consistent with the diagnosis of Guillain-Barré syndrome (GBS).

Conclusion:
COVID-19 activates inflammatory cells and creates a number of inflammatory cytokines and eventually produces immune-mediated processes. Both cell and humoral-dependent pathways of GBS pathogenesis are believed to be related. The peripheral nervous system, myelin, axons, and in some cases, both immune-mediated attacks are believed to be the cause of molecular expression. COVID-19 is believed to induce antibody formation against particular gangliosides. Further study is needed to understand the role of GBS caused by infection with COVID-19.
episteme latinoamericana de cuerpo para pensar lo educativo en clave de presente
Authors: Mallarino Flórez Claudia 
Published: May 2021

Hoy se puede hablar de una “decibilidad” del/sobre el cuerpo -modos de enunciación que se sustentan a sí mismos y crean su propia posibilidad de ser dichos- en América Latina, en términos de discursividades de lo corporal que parecen develar una episteme[1]anclada en saberes profundamente alterados que auguran el umbral de una nueva positividad somática[2], tanto en el nivel regional como en el de las localidades culturales. La escuela[3] no escapa a esta circunstancia, por lo cual, interrogar su idiosincrasia corporal y analizar las transformaciones que, en virtud de ella, afectan la educación parece imprescindible, si queremos interpretar hoy su pertinencia social y el tamaño de su responsabilidad.

[1] Episteme: orden general que rige las configuraciones de saber para una cultura y en una época determinada; el orden, a partir del cual, ciertos discursos pueden producirse y otros no, ciertas cosas pueden ser dichas y otras no; el tejido de disposiciones que producen las variaciones, redistribuciones, articulaciones y desplazamientos del discurso (Foucault, 1968, p. 7-10).
[2] Usamos el significante somático inspirados en la propuesta de Berthelot (1995) que propone el término cultura somática para referirse a lo relativo al cuerpo y a las prácticas corporales como instituidas e instituyentes por/de una cultura. En nuestra propuesta el cuerpo es el continente de una multiplicidad de dimensiones -orgánica, psíquica, cognitiva, ética, comunicativa, espiritual, etc.-, o territorios contenidos en él.
[3] La escuela, por extensión, la vamos a entender aquí como la institucionalidad educativa formal en todos sus niveles: preescolar, básica, media, superior, posgradual.

Published: May 2021

A nivel universitario se ha identificado un problema de bajo rendimiento en los cursos de matemática de formación básica para Ciencias e Ingeniería. En la Universidad Icesi se inició un proyecto de investigación con la caracterización del ambiente de aprendizaje en tres cursos de Álgebra y Funciones. Se formularon categorías de análisis para cuatro dimensiones constitutivas de un ambiente de aprendizaje y se hicieron observaciones centradas en el tema de funciones. En el momento de inicio del proyecto los cursos son presenciales. Las conclusiones sobre las categorías de análisis planteadas señalan la importancia de las condiciones físicas del espacio de interacción (aula de clase) y el efecto negativo, sobre la reflexividad del profesor, que tiene la premura por cubrir un programa estructurado por contenidos. En el artículo se plantean algunos referentes teóricos desde los cuales se pueden proponer soluciones viables al problema de bajo rendimiento, atendiendo a las características contextualizadas de los ambientes de aprendizaje. La socialización del resultado del estudio se constituyó en uno de los factores que impulsó la actual reforma del curso de Álgebra y Funciones, cuyo desarrollo y seguimiento ha sido impactado por la necesidad de migrar a ambientes virtuales durante la pandemia en el año 2020.
«O ewiges Feuer, o Ursprung der Liebe»: Towards the Compositional History of Cantatas by J. S. Bach BWV 34 and 34a
Authors: Шабалина Т.В. 
Published: May 2021

В статье исследуется проблема соотношения оригинала и пародии в кантатах И. С. Баха «O ewiges Feuer, o Ursprung der Liebe» BWV 34 и 34a. На основе изучения сохранившихся рукописей (Am. B. 39 и Mus. ms. Bach St 73) — и главным образом исправлений в них — показано, что существующие представления о первоначальной версии в виде венчальной кантаты BWV 34a, переработанной затем в кантату на Пятидесятницу BWV 34, не соответствуют первоисточникам. Предлагается
новое видение истории создания сочинений, прослеживается направление пародии, прямо противоположное тому, как рассматривалось прежде. Исследование правок в партиях венчальной кантаты
(Mus. ms. Bach St 73) позволяет выявить
характерные особенности подобных приемов в творческом процессе композитора.
Ставятся также более широкие вопросы
понимания закономерностей пародирования им собственных произведений.
The problem of correlation between original and its parody in J. S. Bach’s cantatas «O ewiges Feuer, o Ursprung der Liebe» BWV 34 and 34a is researched in this article. Basing
on a study of surviving manuscripts (Am.B.39 and Mus. ms. Bach St 73) — their corrections in particular — it is shown, that the existing knowledge about the wedding cantata BWV 34a as the first version and the Whitsuntide cantata BWV 34 as its parody does not correspond to their primary sources. A new
conception of the history of Bach’s work on the pieces is suggested, as well as the direction of parody opposite to the generally accepted one is traced. The study of corrections
in the parts of the wedding cantata (Mus. ms. Bach St 73) allows to reveal peculiarities of such means in the compositional process of J. S. Bach. Wider problems of understanding of his self-parody are also discussed.
