Return to Sport From Viral Myocarditis in a Previously Healthy Collegiate Athlete: A Case Report
Authors: Wirtz Abigail
Published: May 2022

The objective of this paper is to present the case of a healthy, 19-year-old female collegiate soccer player who developed acute pulmonary edema and acute heart failure in the recovery room after hip labral arthroscopic surgery. The patient's initial diagnosis, of negative pressure pulmonary edema in direct relation to extubation, was questioned when she became hemodynamically unstable. A cardiac biopsy revealed acute pulmonary edema and heart failure secondary to viral myocarditis. The patient was treated and discharged 10 days after admission. Specific and substantiated return-to-play guidelines after a cardiac event, specifically viral myocarditis, have been sparse. The interprofessional collaboration between athletic trainers and cardiologists is a key dynamic in the clinical decision-making process of a safe return to competitive athletic participation after a cardiac event.

Background: Microcirculatory disturbances are typically most severe during cardiopulmonary bypass (CPB), which occurs during cardiac surgeries. If microvascular reactivity compensates for microcirculatory disturbances during CPB, tissue hypoxemia can be minimized. The primary aim of this study was to assess whether microvascular reactivity during CPB could predict major adverse events (MAE) after cardiac surgery.Methods: This prospective observational study included 115 patients who underwent elective on-pump cardiac surgeries. A vascular occlusion test (VOT) with near-infrared spectroscopy was performed five times for each patient: before the induction of general anesthesia, 30 min after the induction of general anesthesia, 30 min after applying CPB, 10 min after protamine injection, and post-sternal closure. The postoperative MAE was recorded. The area under the receiver operating characteristic (AUROC) curve analysis was performed for the prediction of MAE using the recovery slope.Results: Of the 109 patients, MAE occurred in 32 (29.4%). The AUROC curve for the recovery slope during CPB was 0.701 (P < 0.001; 95% CI [0.606, 0.785]). If the recovery slope during CPB was < 1.08%/s, MAE were predicted with a sensitivity of 62.5% and specificity of 72.7%.Conclusions: Our study demonstrated that the recovery slope of the VOT during CPB could predict MAE after cardiac surgery. These results support the idea that disturbances in microcirculation induced by CPB can predict the development of poor clinical outcomes, thereby demonstrating the potential role of microvascular reactivity as an early predictor of MAE after cardiac surgery.

Published: May 2022

Renal cell carcinoma (RCC) metastasis to the urinary bladder is an exceedingly rare entity. In this paper, we present a case of a 78-year-old male presented in our department with painless gross hematuria, 2 years after he underwent a left open nephrectomy that revealed a clear cell RCC. Imaging examination revealed a sessile mass on the bladder wall. The patient underwent a transurethral resection of the bladder tumor with the histological diagnosis of clear cell RCC. Pathogenesis and possible routes of such a metastasis are not well-documented and no treatment of choice has been established yet.
Mucinous Adenocarcinoma of the Prostate Found Incidentally in Adenomectomy Specimen Complicated with Vesicocutaneous Fistulae
Authors: Theodoros Spinos , Michail Lardas , Grigorios Kotoulas , Anastasios Thanos , Iason Kyriazis
Published: May 2022

Primary mucinous tumors of the prostate gland are rare, including mucinous adenocarcinoma, prostatic adenocarcinoma with mucinous features, and mucinous adenocarcinoma of the prostatic urethra. In this report, we present a case of a locally advanced mucinous variant of prostatic ductal adenocarcinoma, found incidentally during pathology examination of an adenomectomy specimen, after bladder outlet obstruction surgery. Recent large studies indicated that mucinous adenocarcinoma of the prostate, treated by radical prostatectomy, is not more aggressive than ordinary nonmucinous prostatic adenocarcinoma. In our case, the rapid deterioration of our patient, the return of tumor in its initial size soon after surgery, in addition to its distal metastatic spread should be attributed not only to the mucinous variant of prostatic adenocarcinoma but also to the advanced stage during initial diagnosis and the noncompliance of the patient with the suggested treatment after surgery, omitting radiotherapy, and hormonal maneuvers.

Authors: Tzelves Lazaros , Mourmouris Panagiotis , Skolarikos Andreas
Published: May 2022

Medical management of the stone disease is a topic of controversy even between worldwide guidelines. With this review, we attempt to clarify the disparities that exist in the literature and provide to the clinical urologist a tool for battling this common disease. The search was based on current Guidelines from national and international urological Associations including European and American guidelines and the guidelines of Societe d”Urologie. The use of a-blockers is highly indicated by most Guidelines as medical expulsion therapy, whereas nonsteroidal anti-inflammatory medication for pain relief. Fluid intake of 2 lit/day, controlled dietary calcium consumption and sodium restrictions are universal dietary modifications from urological Associations on the prevention of stone disease. Despite methodological heterogeneity and subjective rating of recommendations, an acceptable degree of consensus was noted on Guidelines regarding medical management of the stone disease.

Authors: Sakalis Vasileios , Oliver Rachel , Guy Peter , Davies Melissa
Published: May 2022

Context/Objective:

Vesicoureteric reflux (VUR) is a well-known complication of neurogenic lower urinary tract dysfunction. VUR results to progressive renal deterioration and eventually renal failure. Our aim was to assess the efficacy of Macroplastique bulking agent in managing VUR in spinal cord injury population and correlate the pre- and postintervention VUDS (Video-urodynamics) findings with the outcome.

Design:

Retrospective cohort study.

Participants:

Spinal cord injury patients with VUR, treated with Macroplastique, had pre- and postintervention VUDS and followed up for at least 12 months.

Interventions:

Macroplastique injection and video-urodynamics.

Outcome Measures:

The primary endpoint was the overall treatment rate of VUR at 3 months. The secondary outcomes were the overall treatment rate of VUR at 12 months, the success rate at 3 and 12 months, the need for additional treatments, and the comparison of VUDS parameters in treated versus failed cases.

Results:

Forty-eight patients and 62 refluxing ureteric units were studied. At 3-month follow-up, the overall treatment rate was 79.1%. The overall success rate (treated + improved) was 90.3%. There is a statistically significant difference in baseline cystometric capacity (P = 0.047), degree of reflux (P < 0.01), and bladder compliance (P = 0.023) between the treated and failed cases.

Conclusion:

Macroplastique is effective in the management of VUR in spinal cord injury population. It is minimally invasive, quick, with low complication rates. Care should be taken to treat the parameters of the neurogenic bladder that contributes to secondary VUR development such as detrusor overactivity and poor bladder compliance.
Morphometric and Morphological Variants of Pterion with its Clinical Importance in South Indian Population
Authors: Prasad Mythraeyee , Rout Sipra
Published: May 2022

Background:

Pterion is a critical neuroanatomical landmark in various neurosurgical approaches, including for the placement of burr holes. In addition, it also holds significance from radiological, anthropological, and forensic point of view. Thus, we undertook the current study to investigate the prevalence of different morphological types of pterion along with their morphometric parameters from adjacent bony landmarks in the south Indian population.

Methodology:

A total of 64 adult dry human skulls of unknown gender and age were included for the study. All skulls were grossly normal. The types of pterions were classified on both sides based on Murphy's classification. The vertical linear distance from the center of the pterion to the zygomatic arch (PZ) and to the anterior border of the frontozygomatic suture (PF) was measured with a digital vernier caliper. Data were statistically analyzed.

Results:

All four varieties of pterion were noticed. The sphenoparietal variety was found as most predominant bilaterally (81%), followed by epipteric (12.5%) stellate (3.9%) and frontotemporal (2.39%). One of the epipteric varieties consists of an unusually large ossicle. Pterion was typically located 3.59 ± 0.43cm behind the fronto zygomatic suture and 3.71 ± 0.34 cm above the zygomatic arch.

Conclusion:

The sphenoparietal variant of pterion was predominant on both sides, followed by epipteric variety.

Authors: Sengodan Vetrivel Chezian , Jyothilakshmi G. L. , Masilamani Bharathidasan , Rathinasamy Surendhar
Published: May 2022

Background:

Surgeries involving the proximal third of the fibula are associated with the risk of common peroneal nerve (CPN) injury. Hence, a safe corridor using palpable anatomical landmarks is necessary to avoid injury to the CPN.

Methodology:

Sixty lower limbs (30 fresh cadavers) were in our study group. The distance between the Gerdy's tubercle (GT) and the CPN behind the fibular head (FH), distance from GT to the superficial branch of the CPN (superficial peroneal nerve [SPN]), and distance from GT to the anterior recurrent branch of the CPN (anterior tibial recurrent nerve [ATRN]) were measured, and a safe zone to avoid CPN injury was identified.

Results:

The distance between the GT and the CPN behind the FH was 45.52 ± 2.4 mm, distance from GT to the origin of the SPN was 46.44 ± 2.4 mm, and distance from GT to the ATRN was 45.59 ± 2.9 mm.

Conclusion:

The safe corridor to avoid CPN injury is identified by an arc trajectory with a radius of 45.85 mm with the GT as the center, which will be useful during surgical procedures to avoid injury to the CPN.

Published: May 2022

The effect of information communication technologies utilization on profitability was examined among 120 catfish farmers drawn through a multistage sampling procedure. Data were elicited with the aid of a structured questionnaire, analysed using percentages, budgetary technique and multiple regression model. Agricultural media information sources utilized by the farmers include mobile phone (79.2%), television (76.7%) and radio (68.3%). The result revealed that ₦592,448.90 was expended as cost per annum on fish production with ₦970,700.54 as revenue and a gross margin of ₦438,880.28 among ICT users while for non-ICT users ₦652,067.47, ₦1,026,428.66 and ₦427,337.41 were obtained as total cost, revenue and gross margin respectively. A value of 0.64 realized on the investment among ICT users implies that for every ₦1 invested in catfish farming, ₦1.64 is gotten as returns, leaving a profit of ₦0.64 while a profit of ₦0.57 is realized among non-ICT users. The factors that determine the profitability of catfish farming include household size (10%), input cost (1%) and television usage (5%) as agricultural media information source. Catfish farmers who utilized ICT have a higher profit level than non-users. Efforts and policies that will promote the farmers’ timely availability and accessibility of agricultural information, particularly through television is recommended.

Authors: Latif Raja Mohammad
Published: May 2022

Real-life structures always include indeterminacy. The Mathematical tool which is well known in dealing with indeterminacy is neutrosophic. Smarandache proposed the approach of neutrosophic sets. Neutrosophic sets deal with uncertain data. The notion of neutrosophic set is generally referred to as the generalization of intuitionistic fuzzy set. In 2021, Dr. G. Sindhu introduced the concept of Neutrosophic generalized regular b-closed sets and neutrosophic generalized b-open sets and presented some of their properties in Neutrosophic topological spaces. In this research paper, we introduce the concepts of neutrosophic grb-continuous mappings, neutrosophic grb-irresolute mappings, neutrosophic grb-closed mappings, neutrosophic grb-open mappings, strongly neutrosophic grb-continuous mappings, perfectly neutrosophic grb-continuousmappings, neutrosophic contra grb-continuous mappings and neutrosophic contra grb-irresolute mappings in neutrosophic topological spaces. We investigate and obtain several properties and characterizations concerning these mappings in neutrosophic topological spaces.

This research aims to determine whether there is an influence of applying the Problem Based Learning (PBL) Model with the Technological, Pedagogical, and Content Knowledge (TPACK) Approach on the historical learning outcomes of high school students of Sultan Iskandar Muda Medan. This study uses a quasi-experiment research method. The population in this study involves all students of class XI of High School (SMA) Sultan Iskandar Muda Medan, with a sample of class XI of Social Sciences (IPS) 1 as an experiment class and class XI of Social Sciences (IPS) 3 as a control class selected by simple random sampling method. The experiment class is taught with the PBL Model with the TPACK Approach, while the control class is taught with the Discovery Learning Model. The research instrument used is in the form of test questions totaling 25 multiple choice questions that have been declared valid. In this study, two stages of the test were given, namely pretest and posttest, in the form of multiple-choice questions that have been declared valid. The pretest is given to both sample classes to determine the student's initial ability before being given treatment, while the posttest is given to both sample classes to determine the final ability of learners after treatment. Based on posttest data, the experiment class obtained an average score of 80.3 and an average score in the control class of 68.4. The data proved to be a normal and homogeneous distribution through statistical test analysis, so a hypothesis test was carried out, namely a one-party t-test that showed a significance level of α = 0.05. Thus, Ho was rejected, and Ha was accepted, meaning that there was an influence of the PBL Model with the TPACK Approach on the historical learning outcomes of the high school students.

Published: May 2022

Self-regulation is important at every stage of the education process and must be measured accurately in order to know at what students’ levels are. The aim of this study is to develop a scale that is able to validly and reliably determine the self-regulation levels of secondary school students regarding science. The study uses the survey design, a quantitative research method. The sample of the research consists of 500 students enrolled in three secondary schools in Kayseri Province’s Melikgazi district during 2018 spring semester. While preparing the scale, which was developed based on social cognitive theory, a literature review was conducted, expert opinions were sought, and a pilot study was conducted to test the suitability of the items. Exploratory and confirmatory factor analyses (EFA and CFA) were performed to ensure the construct validity. As a result of the EFA, a structure consisting of 26 questions was obtained whose three factors explain 48% of the variance. This structure was confirmed through CFA, which was conducted on the data obtained from a sample different than the one used in the EFA. Cronbach’s alpha of reliability for the scale was calculated as .940. As a result, a valid and reliable scale for science education based on social cognitive theory and Zimmerman’s self-regulation model was obtained that is simple enough that middle school student can understand it.

Predicting Mathematics Performance by ICT Variables in PISA 2018 through Decision Tree Algorithm
Authors: Simsek Mertkan
Published: May 2022

Considering the large volume of PISA data, it is expected that data mining will often be assisted in making PISA data more meaningful. Studies show that different dimensions of ICT may reveal different relationships for mathematics achievement. The purpose of this article is to evaluate the success of the decision tree classification algorithms in predicting the effect of ICT on students' mathematics performance. The population of the research consists of 15-year-old students studying in Turkey. The sample of the study consists of 6570 students who participated from Turkey and gave adequate answers to the ICT Familiarity Questionnaire in PISA and whose mathematics score was calculated. The J48 algorithm is more successful in classifying students with low mathematics achievement than classifying students with high mathematics achievement. The rate of correctly predicting mathematics achievement with weighted average values and variables related to ICT is 66.1%. ENTUSE [ICT use outside of school (leisure)], ICTCLASS [Subject-related ICT use during lessons] and USESCH [Use of ICT at school in general] variables are the most effective variables. It is thought that the reason for the difference in the effect of the use of information and communication technologies for entertainment purposes on mathematics achievement is since the level of recreational use can have a positive effect up to a certain level, while excessive use can be harmful.

Authors: Cuvi Nicolás
Published: May 2022

¿Qué ciudad tuvimos y tenemos? ¿Cuál queremos? ¿Tiene la naturaleza un lugar en Quito? A esas y otras preguntas Nicolás Cuvi responde con pasión y profundidad analítica en esta obra. Así como el agua tiene memoria y recuerda sus cauces, sostiene el autor, otros actores no humanos de la ciudad poseen una historia y una ecología. Cuvi traza un paisaje donde convergen plantas y animales, ríos, residuos e iniciativas de sustentabilidad. Situado en el biocentrismo contemporáneo, puebla a la urbe quiteña con esos actores, para posicionar el derecho de la naturaleza a la ciudad y el de la ciudadanía a la naturaleza. Analiza estructuras mentales, relaciones de poder y mitos que fomentan la inercia social, así como acciones que transforman las prácticas individuales, colectivas y políticas. Quienes se encargan del gobierno y la gestión de la ciudad, o la investigan, encontrarán un libro clave sobre la complejidad socioambiental de Quito. Una reflexión aguda sobre la tensión histórica y presente entre pulsiones de muerte, cómodas e insustentables, y pulsiones de vida, luminosas y renovadoras.

The technique of determining whether a text is good, negative or neutral is known as sentiment analysis (SA).Sentiment Analysis can be identified by many names like Textual Analysis, Opinion Mining. Sentiment Analysis is a branch of Natural Language Processing (NLP) that focuses on the expression of subjective views and feelings about a topic gathered from multiple sources. Sentiment Analysis is a collection of methods for detecting and extracting opinions and uses them for the benefit of business operation. It is a classification algorithm aimed at finding opinions and decision-making point of view. Sentiment Analysis is performed in many ways, Automatic classification approach involves Nave Bayes (NB), Support Vector Machine (SVM), and Linear Regression is examples of supervised machine learning methods (LR). The data is explored using unsupervised machine learning. Recurrent Neural Network (RNN) derivatives are also used for classification. Rule-based approach involves various NLP process for classification.

S obzirom na to da je lipnja 2021. ponovno oživljena rasprava o porijeklu koronavirusa, u okviru dobro poznate dihotomije šišmiš ili laboratorij, članak iznosi pregled činjenica koje smo u Hrvatskoj naučili u doba pandemije koronavirusa o tom nažalost demoniziranom i navodnom uzročniku pandemije. Naime, jedan o povoda za oživljavanje rasprave o nerazjašnjenom porijeklu koronavirusa bio je i članak objavljen svibnja 2021. u Wall Street Journalu, temeljen na neobjavljenom izvještaju američkih obavještajaca u kojem se tvrdi da je troje znanstvenika Instituta za virologiju u Wuhanu (WIV) hospitalizirano u studenome 2019., gotovo dva mjeseca prije no što je Kina prijavila novu bolest. Veliku ulogu u pozitivnoj medijskoj slici šišmiša kod nas imala je Udruga za zaštitu šišmiša Tragus koja je upozorila, primjerice, što se tiče Zagreba, i na tzv. dobre strane potresa (iz 2020. godine) s obzirom na to da su ugrožene kolonije šišmiša nakon potresa pronašle utočište u napuklinama brojnih zagrebačkih zgrada (usp.

Digital Soul
Authors: Delić Amela
Published: May 2022

The Internet age of media communication has been gradually and subtly changing the way in which we experience ourselves and the world we live in. Broadcasting our lives on the web also involves the everyday exteriorization of emotions onto the technical mediators of the third degree, as Jensen calls them (2006). Expressions of emotional experience is something we see every day on social networks, but they are also becoming an integral part of user content under the media text on web portals. These so-called intellectual technologies are acquiring some of the essential human characteristics such as rationality, memory, calculation, and translation, as well as emotionality and communication (Carr 2014, Turkle 2011).Where do Emotions live when we transfer them into the virtual world and how do they become an integral part of media content? Where does one’s soul live when transferred to one’s virtual self? These are the questions we will try to answer in the first part of this paper. We will analyse the virtual space, its possibilities and limitations. We will discuss the potential of online media to mediate emotional experiences. We will also seek to understand technology and devices as an alternative humanity, when people fail or refuse to act by themselves. We will try to find answers to questions about the consequences of such mediation, referring to the research of other scholars including Siva Vaidhyanathan, Sherry Turkle, Nicholas Carr, and others.In the second part, we will discuss the subtle encroachment of the emotional upon the world of the media. The last part of the paper will present some literary analyses of media intermediation that sporadically appear in works by world-renown writers (Rushdie, Hugo, Mehmedinović, Sábato, Spengler...) and the interaction of their understanding of the media with McLuhan’s view of media intermediation and the extension/mutilation of senses.
Factores asociados al emprendimiento de migrantes colombianos retornados: una aproximación Bayesiana

Published: May 2022

En este estudio se identifica un conjunto de características asociadas al hecho de que un migrante colombiano retornado se convierta en un emprendedor. El análisis se realizó con los datos recogidos en la encuesta Global Entrepreneurship Monitor (GEM) cuyo formulario fue modificado en el año 2012 (solo por ese año) con un conjunto de preguntas sobre emprendimiento a personas que habían retornado al país después de vivir fuera cierto tiempo. Se realizó la comparación entre las probabilidades de emprendimiento en dos regiones del país, Bogotá la capital, área de mayor desarrollo económico y financiero (n=204) y los departamentos de la Costa Caribe Colombiana, área de menor desarrollo industrial y mayor fortaleza turística (n=203). Los resultados fueron obtenidos utilizando métodos propios del paradigma Bayesiano de la Estadística. Se consideraron nueve distribuciones previas informativas construidas a partir de los datos observados (Empirical Bayes Methods) y se utilizó el factor de Bayes como criterio para seleccionar el modelo con mejor ajuste a los datos. De acuerdo con los resultados, los factores que afectan la probabilidad de que un migrante retornado sea emprendedor difieren entre regiones y están relacionados con la autoconfianza del individuo y su capacidad de prepararse para su inclusión en el sector productivo del país.

Alzheimer’s Disease: Criteria for Dental Treatments
Authors: Goldberg Michel
Published: May 2022

Among manifestations of neurodegenerative diseases, Alzheimer Disease (AD) contributes for 60-70% to elderly dementia. AD patients suffer from impaired cognitive function and from a compromised capacity to perform activities of daily living. Neurodegenerative diseases are characterized by neuronal loss, dystrophic neurites, and cerebrovascular amyloid. AD occurs more often in woman (2/3 of AD cases) compared with men. The presence of extracellular β-amyloid peptide and hyper phosphorylated tau protein are typical of the physiopathology of the AD brain. Developed under the age of 65 years, the PSEN1 gene is located on chromosome 14q24.3. In the elderly over 65 years, the late-onset of AD, the gene coding for PSEN2 is located on chromosome 1q31-q42. For the late onset AD, the apolipoprotein E was associated to the main risk factors of developing the disease (including molecules such as clusterin, complement receptor, phosphatidylinositol binding clathrin assembly protein and sortilin). Four genes have been identified on chromosome 11. The Amyloid P Protein precursor (APP) encoded by the gene (APP) is located on chromosome 21q. Altered APP processing and Aβ accumulation shed light on the AD pathogenesis. TNFα may act as a diagnostic marker with high sensitivity and specificity in patients with AD. Studies have identified altered oral health conditions (periodontitis, caries, gingival bleeding, probing depth >4 mm). Poor gingival health and oral hygiene increase with the severity of dementia. Dental professionals should use behaviour management techniques for developing preventive strategies in order to stabilize the lesions.
