Polynomially Bounding the Number of Minimal Separators in Graphs: Reductions, Sufficient Conditions, and a Dichotomy Theorem
Authors: Milanič Martin , Pivač Nevena
Published: March 2021

A graph class is said to be tame if graphs in the class have a polynomially bounded number of minimal separators. Tame graph classes have good algorithmic properties, which follow, for example, from an algorithmic metatheorem of Fomin, Todinca, and Villanger from 2015. We show that a hereditary graph class $\mathcal{G}$ is tame if and only if the subclass consisting of graphs in $\mathcal{G}$ without clique cutsets is tame. This result and Ramsey's theorem lead to several types of sufficient conditions for a graph class to be tame. In particular, we show that any hereditary class of graphs of bounded clique cover number that excludes some complete prism is tame, where a complete prism is the Cartesian product of a complete graph with a $K_2$. We apply these results, combined with constructions of graphs with exponentially many minimal separators, to develop a dichotomy theorem separating tame from non-tame graph classes within the family of graph classes defined by sets of forbidden induced subgraphs with at most four vertices.
Supersaturation, Counting, and Randomness in Forbidden Subposet Problems
Authors: Gerbner Dániel , Nagy Dániel T. , Patkós Balázs , Vizer Máté
Published: March 2021

In the area of forbidden subposet problems we look for the largest possible size $La(n,P)$ of a family $\mathcal{F}\subseteq 2^{[n]}$ that does not contain a forbidden inclusion pattern described by $P$. The main conjecture of the area states that for any finite poset $P$ there exists an integer $e(P)$ such that $La(n,P)=(e(P)+o(1))\binom{n}{\lfloor n/2\rfloor}$.

In this paper, we formulate three strengthenings of this conjecture and prove them for some specific classes of posets. (The parameters $x(P)$ and $d(P)$ are defined in the paper.)

For any finite connected poset $P$ and $\varepsilon>0$, there exists  $\delta>0$ and an integer $x(P)$ such that for any $n$ large enough, and $\mathcal{F}\subseteq 2^{[n]}$ of size $(e(P)+\varepsilon)\binom{n}{\lfloor n/2\rfloor}$, $\mathcal{F}$ contains at least $\delta n^{x(P)}\binom{n}{\lfloor n/2\rfloor}$ copies of $P$.

The number of $P$-free families in $2^{[n]}$ is $2^{(e(P)+o(1))\binom{n}{\lfloor n/2\rfloor}}$.

Let $\mathcal{P}(n,p)$ be the random subfamily of $2^{[n]}$ such that every $F\in 2^{[n]}$ belongs to $\mathcal{P}(n,p)$ with probability $p$ independently of all other subsets $F'\in 2^{[n]}$. For any finite poset $P$, there exists a positive rational $d(P)$ such that if $p=\omega(n^{-d(P)})$, then the size of the largest $P$-free family in $\mathcal{P}(n,p)$ is $(e(P)+o(1))p\binom{n}{\lfloor n/2\rfloor}$ with high probability.

Systemic Therapy in Pediatric-Type Soft-Tissue Sarcoma
Authors: Ingley K.M. , Cohen-Gogo S. , Gupta A.A.
Published: March 2021

Soft-tissue sarcoma (sts) is rare and represents approximately 7% of cancers in children and in adolescents less than 20 years of age. Rhabdomyosarcoma (rms) is most prevalent in children less than 10 years of age and peaks again during adolescence (16–19 years of age). Multi-agent chemotherapy constitutes the mainstay of treatment for rms. In other non-rhabdomyosarcoma soft-tissue tumours, such as synovial sarcoma, evidence for routine use of chemotherapy is less robust, and alternative treatment options, including targeted agents and immunotherapy, are being explored. In this review, we focus on chemotherapy for pediatric-type rms and discuss the advances and challenges in systemic treatment for select non-rhabdomyosarcoma soft-tissue tumours in children and adolescents. We support an increasingly cooperative approach for treating pediatric and adult sts.

Chest Wall Toxicity after Stereotactic Radiation in Early Lung Cancer: A Systematic Review
Authors: Voruganti I.S. , Donovan E. , Walker-Dilks C. , Swaminath A.
Published: March 2021

Background: Radiation-induced chest wall pain (CWP) and rib fracture (RF) are late adverse effects after stereotactic body radiation therapy (SBRT) for stage i non-small-cell lung cancer (NSCLC); however, the literature about their incidence and risk factors shows variability. We performed a systematic review to determine the pooled incidence of CWP and RF in the relevant population. Methods: A literature search using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines considered English publications in MEDLINE and EMBASE from January 1996 to August 2017. Abstracts were screened, followed by full-text review and data extraction. Results: The database searches identified 547 records. Twenty-eight publications comprising 3892 patients met the inclusion criteria. Median reported ages and follow-up durations fell into the ranges 67–82 years and 12–84 months. Prescriptions fell into the range of 40–70 Gy in 3–10 fractions. Despite study heterogeneity, the pooled incidences of CWP and RF were estimated to be 8.94% and 5.27% respectively. Nineteen studies reported cwp grade: 58 of 308 patients (18.8%) experienced grades 3–4 CWP (no grade 5 events reported). Thirteen studies reported RF grade: grades 3–4 RF were observed in 9 of 113 patients (7.96%). A high chest wall V30 was an important predictor of CWP and RF. Conclusions: In patients with stage i nsclc, rates of CWP and RF after SBRT are low; however, tumour location, accurate toxicity reporting, and dose–fractionation schemes might alter those rates. Prospective correlation with dosimetry and quality of life assessment will further improve the understanding of CWP and RF after sbrt.

Authors: Dyakov I. N. , Zyryanov S. K.
Published: March 2021

Effective control of Diabetes Mellitus (DM) is an actual task from clinical and economic points of view. The second generation insulin analogs increase level of DM compensation without hypoglycemia. The economic aspects of their usage have been evaluated early, but it is still actual due to changes in prices and new data about clinical efficacy were published.

Materials and methods: Clinical-economic comparison of insulin glargine 300 U/ml (iGla 300), insulin degludec (iDeg) and insulin degludec/ insulin aspart (iDegAsp) in the Russian conditions has been performed in naïve patients’ group as well as in the group of patients with previous insulintherapy. Number of patients with HbA1c <7 % was chosen as efficacy criterion. Direct and indirect costs (medications, treatment of CV-complications, GDP loses etc.) were indicated and calculated based on the constructed model.

Results: iGla 300 can give an economy till 20 % for medication cost and till 10 % for direct medical expenditures in compare with iDeg in DM Type 1. For both patients’ groups iGla 300 can save 10-23 % of sources in compare with iGed and iDegAsp in DM Type 2. In DM2T iGla 300 had more efficacy and less cost in compare with iDeg in elderly patients with renal insufficiency.

Conclusion: An effective control of DM with modern insulins is profitable from government position of payment due to decreasing expenditures for complications treatment.

El gen culpable: imaginarios de justicia y genética en torno al Registro Nacional de Datos Genéticos en Argentina
Authors: Barán Taly , Peralta Amalia
Published: March 2021

La tecnología genética presenta usos cada vez más diversos y extendidos. Sin embargo, son circunstancias muy específicas en las que esta pasa a formar parte de los temas de debate público. Así ocurrió en Julio de 2013, en Argentina, con la creación del Registro Nacional de Datos Genéticos de Delitos contra la Integridad Sexual más conocido como “Registro de Violadores”. El proceso de aprobación de esta ley abrió espacios de diálogo en los que la genética se erigió como una pieza central del discurso de diversos actores.

En este artículo se centra la atención en el análisis de este caso ya que permite abordar a la genética en tanto significante cargado de sentidos sociales en constante transformación. Se parte de una estrategia metodológica cualitativa a partir de la análisis de declaraciones públicas y de entrevistas realizadas a actores participantes del debate en torno a la aprobación de la normativa. Se propone reconstruir los imaginarios de genética, violador y justicia que confluyeron en torno a la configuración de esta ley a la vez que se plantean preguntas por los cambios que los usos novedosos de la genética acarrean sobre las concepciones de cuerpo y seguridad.

Se concluye que en torno a esta ley es posible encontrar diálogos e intersecciones entre grandes marcos productores de discursos, imaginarios y nuevos dilemas de las sociedades contemporáneas.

La estructura de simpatía en Las oscuras pimaveras
Authors: Espinosa Pacheco Ilia Lizbeth
Published: March 2021

Los estudios cognitivos de cine constituyen un programa de investigación que aborda diversos fenómenos relacionados con los procesos mentales, emocionales y afectivos del espectador a partir de las aportaciones interdisciplinarias entre la teoría de cine y las ciencias cognitivas. Murray Smith (2004), en su libro Engaging Characters, ha desarrollado la “Estructura de Simpatía”, un sistema de análisis textual que permite explicar las respuestas emocionales de los espectadores a los personajes de ficción. Este esquema conformado por los procesos de reconocimiento, alienación y lealtad aplicado a la película Las oscuras primaveras (Ernesto Contreras, 2014), como parte de un acercamiento teórico metodológico para el estudio de la construcción del imaginario amoroso en el cine mexicano contemporáneo, muestra que la mímesis afectiva tiene un poder extraordinario para interrumpir o cambiar la reorganización moral de la estructura narrativa de un filme, obligando al espectador a reflexionar sus juicios morales sobre el mismo.
Magellanic Mayhem: Metallicities and Motions
Authors: Grady J. , Belokurov V. , Evans N. W.
Published: March 2021

We assemble a catalog of Magellanic Cloud red giants from Data Release 2 of the Gaia mission and, utilizing machine-learning methods, obtain photometric metallicity estimates for them. In doing so, we are able to chemically map the entirety of the Magellanic System at once. Our maps reveal a plethora of substructure within our red giant sample, with the Large Magellanic Cloud (LMC) bar and spiral arm being readily apparent. We uncover a curious spiral-like feature in the southern portion of the LMC disk, hosting relatively metal-rich giants and likely a by-product of historic encounters with the Small Magellanic Cloud (SMC). Modeling the LMC as an inclined thin disk, we find a shallow metallicity gradient of −0.048 ± 0.001 dex kpc−1 out to ∼12° from the center of the dwarf. We see evidence that the SMC is disrupting, with its outer isodensity contours displaying the S-shape symptomatic of tidal stripping. On studying the proper motions of the SMC giants, we observe a population of them being violently dragged toward the larger Cloud. The perturbed stars predominantly lie in front of the SMC, and we interpret that they exist as a tidal tail of the dwarf, trailing in its motion and undergoing severe disruption from the LMC. We find the metallicity structure in the Magellanic Bridge region to be complex, with evidence for a composite nature in this stellar population, consisting of both LMC and SMC debris.
A Multi–Observing Technique Study of the Dynamical Evolution of the Viscous Disk around the Be Star ω CMa
Authors: Ghoreyshi Mohammad R. , Carciofi Alex C. , Jones Carol E. , Faes Daniel M. , Baade Dietrich , Rivinius Thomas
Published: March 2021

The observed emission lines of Be stars originate from a circumstellar Keplerian disk, which is generally well explained by the viscous decretion disk model. In an earlier work we performed modeling of the full light curve of the bright Be star ω CMa with the 1D time-dependent hydrodynamic code SINGLEBE and the Monte Carlo radiative transfer code HDUST. We used a V-band light curve that probes the inner disk through four disk formation and dissipation cycles. This new study compares predictions of the same set of model parameters with time-resolved photometry from the near-UV through the mid-IR, comprehensive series of optical spectra, and optical broadband polarimetry, which overall represent a larger volume of the disk. Qualitatively, the models reproduce the trends in the observed data due to the growth and decay of the disk. However, quantitative differences exist, e.g., an overprediction of flux increasing with wavelength, too slow decreases in Balmer emission line strength during disk dissipation, and a discrepancy between the range of polarimetric data and the model. We find that a larger value of the viscosity parameter alone or a disk truncated by a companion star reduces these discrepancies by increasing the dissipation rate in the outer regions of the disk.
Particle Dynamics in 3D Self-gravitating Disks. I. Spirals
Authors: Baehr Hans , Zhu Zhaohuan
Published: March 2021

Spiral arms are distinctive features of many circumstellar disks, observed in scattered light, which traces the disk surface; millimeter dust emission, which probes the disk midplane; as well as molecular emission. The two leading explanations for spirals are wakes generated by a massive planet and the density waves excited by disk self-gravity. We use stratified 3D hydrodynamic shearing-box simulations including dust particles and disk self-gravity to investigate how gas and dust spirals in a self-gravitating disk depend on the simulation size, the cooling efficiency, and the aerodynamic properties of particles. We find that the opening angles of spirals are universal (∼10°) and not significantly affected by the size of the computational domain, the cooling time, or the particle size. In simulations with the biggest domain, the spirals in the gaseous disk become slightly more open with a higher cooling efficiency. Small dust follows the gaseous spirals very well, while intermediate-sized dust with dimensionless stopping time (St) close to 1 is more concentrated in the spirals and shows stronger spirals. However, large dust with St > 1 also shows spirals, which is different from some previous simulations. We identify that this is due to the gravity from the gas to the dust component. We show that when St ≳ Q, the gravitational force from the gaseous spirals on the dust particles becomes stronger than the particles’ aerodynamic drag force, so that the gas significantly affects these large particles through gravitational interaction. This has important implications for both spiral observations and planetesimal formation/dynamics.
Multiwavelength Observations of the RV Tauri Variable System U Monocerotis: Long-term Variability Phenomena That Can Be Explained by Binary Interactions with a Circumbinary Disk

We present an X-ray through submillimeter observations of the classical RV Tauri (RVb-type) variable U Mon, a post-asymptotic giant branch (AGB) binary with a circumbinary disk (CBD). Our SMA observations indicate a CBD diameter of ≲550 au. Our XMM-Newton observations make U Mon the first RV Tauri variable detected in X-rays. The X-ray emission is characteristic of a hot plasma (∼10 MK), with L
X =5 × 1030 erg s−1, and we consider its possible origin from U Mon, its companion, and/or binary system interactions. Combining DASCH and AAVSO data, we extend the time-series photometric baseline back to the late 1880s and find evidence that U Mon has secular changes that appear to recur on a timescale of ∼60 yr, possibly caused by a feature in the CBD. From literature radial velocities we find that the binary companion is a ∼2 M
⊙ A-type main-sequence star. The orientation of the binary’s orbit lies along our line of sight (ω = 95°), such that apastron corresponds to photometric RVb minima, consistent with the post-AGB star becoming obscured by the near side of the CBD. In addition, we find the size of the inner-CBD hole (∼4.5–9 au) to be comparable to the binary separation, implying that one or both stars may interact with the CBD at apastron. The obscuration of the post-AGB star implicates the companion as the likely source of the enhanced Hα observed at RVb minima and of the X-ray emission that may arise from accreted material.
A fast high order method for time fractional diffusion equation with non-smooth data
Authors: Qiao Haili , Cheng Aijie
Published: March 2021

In this paper, we consider the time fractional diffusion equation with Caputo fractional derivative. Due to the singularity of the solution at the initial moment, it is difficult to achieve an ideal convergence order on uniform meshes. Therefore, in order to improve the convergence order, we discrete the Caputo time fractional derivative by a new \begin{document}$ L1-2 $\end{document} format on graded meshes, while the spatial derivative term is approximated by the classical central difference scheme on uniform meshes. We analyze the approximation about the time fractional derivative, and obtain the time truncation error, but the stability analysis remains an open problem. On the other hand, considering that the computational cost is extremely large, we present a reduced-order finite difference extrapolation algorithm for the time-fraction diffusion equation by means of proper orthogonal decomposition (POD) technique, which effectively reduces the computational cost. Finally, several numerical examples are given to verify the convergence of the scheme and the effectiveness of the reduced order extrapolation algorithm.
Small data blow-up of semi-linear wave equation with scattering dissipation and time-dependent mass
Authors: Ikeda Masahiro , Tu Ziheng , Wakasa Kyouhei
Published: March 2021

In the present paper, we study small data blow-up of the semi-linear wave equation with a scattering dissipation term and a time-dependent mass term from the aspect of wave-like behavior. The Strauss type critical exponent is determined and blow-up results are obtained to both sub-critical and critical cases with corresponding upper bound lifespan estimates. For the sub-critical case, our argument does not rely on the sign condition of dissipation and mass, which gives the extension of the result in [14]. Moreover, we show the blow-up result for the critical case which is a new result.
Le retour du mythe des passages arctiques : quel trafic maritime dans l’Arctique au XXIe siècle ?
Authors: Lasserre Frédéric
Published: March 2021

Dans le contexte des changements climatiques et de la fonte accélérée de la banquise arctique, les médias et bon nombre d’articles scientifiques se font l’écho des possibles autoroutes maritimes qui structureraient les passages arctiques au XIXe siècle. Ces scénarios reposent souvent sur la projection de la fonte de la glace, des analyses de coûts et l’idée que des trajets plus courts seront nécessairement attractifs, mais négligent les aspects logistiques et économiques de la navigation commerciale en mer englacée. Leur enthousiasme s’enracine plutôt dans une lecture fantasmée des passages arctiques héritée des grands voyages d’exploration du XVIe au XIXe siècle.
Quand la littérature de jeunesse scandinave se met à l’heure viking : La reconstruction d’un mythe
Authors: Jarl Ireman Annelie
Published: March 2021

L’ère viking ne cesse d’être reprise dans la littérature et la culture populaire. Cet article se propose d’analyser l’image transmise par la littérature de jeunesse scandinave. Conformément à une intention pédagogique importante dans ce genre, les auteurs veulent transmettre des connaissances et une vision historiquement crédible, voire corriger des idées reçues. Désacralisé, le Viking devient plus complexe. Les figures mythologiques sont, elles aussi, revisitées pour devenir plus nuancées. Il s’agit avant tout de transmettre des valeurs positives de cette époque, comme le courage et l’honneur, mais aussi l’égalité, tout en dénonçant par exemple la violence et l’esclavage. Mettre en avant les enfants et les femmes et parler de la vie quotidienne sont également une façon de corriger l’historiographie. Ainsi, cette époque considérée comme le point de départ des cultures scandinaves, reste importante pour l’identité nordique puisqu’elle représente un passé commun mythifié. Réinterprétée, elle maintient sa place dans la mémoire collective et peut fonctionner comme un idéal contemporain.
Du Vennamoïsme au parti des Finlandais : généalogie du populisme en Finlande
Authors: Blanc-Noël Nathalie
Published: March 2021

Jusqu’au début du 21ème siècle, la Finlande passait pour une exception politique en Europe, n’étant pas concernée par la montée du populisme de droite radicale. Cette situation changea du tout au tout au cours des années 2010, en particulier lorsque le parti des Finlandais obtint le second meilleur score aux élections législatives de 2011. Depuis lors, ce parti constitue l’une des toutes premières forces politiques dans ce pays. Cet article explore ses origines historiques ainsi que son idéologie, du Parti rural fondé par Veikko Vennamo dans les années 1960 jusqu’au parti des Finlandais et à Réforme Bleue aujourd’hui.
Le primitivisme emphatique et critique. Les voies du primitivisme finlandais dans Putkinotko de Joel Lehtonen
Authors: Rossi Riikka
Published: March 2021

Dans cet article, nous nous proposons d’étudier, à travers le roman Putkinotko (1919-1920) de Joel Lehtonen, les formes du primitivisme finlandais et d’examiner les rencontres du primitif et du civilisé dans l’imaginaire de l’époque. Dans la littérature finlandaise de l’époque, les classes agraires sont devenues essentielles pour imaginer le primitif entre nous et pour raconter l’histoire d’une jeune nation à l’aube de la modernité. En outre, l’analyse du roman de Lehtonen nous permet de réfléchir sur l’idée du primitivisme en tant que conception esthétique et courant littéraire. Même si le primitivisme a été fréquemment considéré comme un projet colonisant de l’époque impérialiste, il nous semble nécessaire de nuancer et de réviser ce point de vue afin de mettre l’accent sur le potentiel critique du primitivisme littéraire et artistique, voire sur son horizon décolonisant. Dans le roman de Lehtonen, une double rhétorique se met en place : le regard et la voix scientifique et civilisée du narrateur sont couplés avec le point de vue des pauvres gens et leur expérience de l’oppression. La visée anthropologique se transforme en une esthétique critique au moyen de l’évocation des émotions, et est destinée à stimuler le sens éthique du lecteur, une empathie réflective qui met en question les injustices sociales décrites dans le roman. Cet esprit de la transgression, qui se développe dans l’écriture de Lehtonen, tient à contester les hiérarchies et les oppositions entre la civilisation et le monde primitif.

The Novel Coronavirus 2019 (SARSCoV-2), which was first reported on in Wuhan, China, in late December 2019, causes a respiratory illness called COVID-19 Disease. COVID-19 is most likely causing a hypercoagulable state, however the prevalence of acute venothromboembolism is still unknown. Limited data suggest pulmonary microvascular thrombosis may play a role in progressive respiratory failure. Here, we report a case of a child with an unusual presentation of COVID-19 presented initially by dry cough without fever and complicated by massive acute pulmonary embolism and lung infarction and treated successfully by hydroxychloroquine and azithromycin, in addition to anticoagulant therapy.
Outpatient Management of Febrile Neutropenia in Children with Cancer
Authors: Ziino Ottavio , Tucci Fabio , Rossi Mario Renato
Published: March 2021

Optimizing the therapeutic strategies based on the results of randomized studies comparing different regimens led to a better prognosis of nearly all pediatric malignancies during the past four decades. Fever and neutropenia (FN) is a common complication in patients undergoing chemotherapy to treat cancer. There is no consensus on when standard therapy can be safely reduced; this lack of consensus leads to important variations in management of FN between different institutions, usually conducted according to local attitudes. To address this issue, the Infection working group of the Italian association for pediatric hematology oncology (AIEOP) organized a consensus meeting. This paper reports the agreement derived from this meeting.

Introduction: The purpose of our study is to compare between physical activity (PA) in postmenopausal women with osteoporotic vertebral fractures and healthy women and to evaluate the relationship between PA and clinical and paraclinical parameters related to osteoporotic fracture.

Methods: A case-control cross- sectional study, which included 128 postmenopausal women with densitometric osteoporosis as defined by Worlds Health Organization, with at least one radiological vertebral fracture. Physical activity was assessed by the International Physical Activity Questionnaire (IPAQ) short version with three items: vigorous, moderate activity and walking. Bone mineral density (BMD) and X-rays were performed in all patients. The controls were healthy women included in a randomized order in the general population, they were matched for age.

Results: 128 patients with a mean age of 61.01± 8.40 years were included. 100 controls were included with a mean age of 60.61 ± 8.25 years. The patients had a median age of menopausal of 48.90 years [48-50], were osteoporotic in 49.2% and had osteopenia in 34.9%. 84 patients had a current back pain, and an average of three vertebral fracture with a median Genant score of 3.02[1-23]. There was no significant difference between the subjects of our study for total PA. However, vigorous-intensity activity and walking were significantly different between the two groups (p<0.05). Three independent factors were associated with a reduction of total physical activity: age, Genant score and physical function (for all p<0.05). In multivariate analysis, a significant association between total physical activity and age (p=0.003), trochanter BMD (p=0.01), Genant score (p=0.02) and physical function (2nd domain QUALEFFO) (p=0.01) persisted.

Conclusion: In Moroccan postmenopausal women with osteoporotic vertebral fractures, PA is decreased with the severity of vertebral fractures and with the increasing age.

CFD analysis of peripheral ECMO cannulation
Authors: Fragomeni Gionata , Rossi Michele
Published: March 2021

"ECMO (Extra Corporeal Membrane Oxygenation) is a technique supporting vital functions through extracorporeal circulation, by raising blood oxygenation, reducing the blood values of carbon dioxide (CO2), increasing cardiac output and acting on body temperature. In conditions of severe respiratory and/or cardiac insufficiency, it allows to rest heart and lungs while performing their ventilation and pump functions. The most common sites for establishing peripheral ECMO are femoral artery and vein. The main goal of ECMO cannulation is to provide the least traumatic and most durable and simplified method for delivering the blood to and from the circuit. There are several ways to connect ECMO to the venous/arterial system. The present study’s aim is to analyse one connection by anastomoses and another one by cannula through a Computational Fluid Dynamics (CFD) model."
Towards an adaptive decision-support system for Type I Diabetes treatment based on simulation and machine learning

"Diabetes is one of the most prevalent chronic diseases in the world, especially in middle- and low-income countries. Inter- and intra-patient variability greatly hinders the establishment of effective treatments by clinicians, even among those most experienced. This variability also prevents health administrations to establish adequate controls that guarantee the application of the most cost-effective interventions. In this work, we propose a decision support system that uses simulation and machine learning as tools to provide the clinician with information adapted to the patient on the best intervention for a patient in terms of effectiveness and cost-effectiveness."

Authors: Molinari Giuseppe , Molinari Martina
Published: March 2021

"To quantify the costs for each situation at risk of sudden death identified by ECG screening using a Telecardiology system. ECGs received at the Telecardiology Center (Telemedico Srl, Genoa) for non-competitive sports, in the September-November 2018 period were analyzed. A total of 4360 non- competive athletes (2113 women, 48.5%) were evaluated between the ages of 3 and 40 years (mean ± SD: 17.3 ± 10.6). The average cost per ECG was € 9.2. An ECG pattern at risk of sudden death has been identified in 319 (7.3%) subjects, respectively 259 (5.9%) at low risk and 60 (1.4%) at medium-high risk. The cost of ECG screening to identify a risk situation was € 125.74 and rose to € 668.53 in the identification of a medium-high risk situation of sudden death. The low costs of the ECG performed by Telecardiology justifies its use in the screening of heart disease at risk of sudden death even in subjects practicing noncompetitive sports."
Puppet mentoring: a new simulation scenario for learning surgical abilities

"Surgical simulators are now able to teach in a way that the learning curve of young surgeons can progress in a lab faster than when using other teaching models (cadaveric or animal) or real patients. The impact of surgical simulators is confirmed by the fact that, in the US, standardized training courses are needed to acquire the Board of Surgery certification. The virtual simulator set up at the University of Genoa (eLaparo4D) is based on two key features: a convincing haptic feedback and a limited cost. Nevertheless, the main issue of eLaparo4D is the “simplicity” of the virtual scenario. To improve it, a new model of simulation is proposed in this project: the “puppet mentoring”, that might enhance its characteristics. The “puppet mentoring” is based on the recording of the movements of the surgeon in the real clinical scenario, that are transferred to the virtual machine. The apprentice, in his learning session, could be led through the operation by the simulator itself, in a scenario and in a way is the same of the real one."

"Cardiovascular disease (CVD) affects daily living functionality, cognitive ability, and mood. We evaluated the effects of a CVD risk score on disability and assessed the characteristics that may modify this relationship in 192 older adults (mean age: 65.6 years, 96 women). WHODAS 2.0 was used to measure global disability and mobility difficulty. Framingham Risk Score (FRS) was used to predict 10-year cardiovascular mortality risk. Sociodemographic characteristics, mental status, overall mood, and gait speed were evaluated for their potential modification of the effect of FRS on WHODAS. We used general linear models to estimate the main effect and interaction effects for the modifiers. A higher effect of FRS was significantly associated with worse WHODAS total score and mobility subscore. We found female gender, younger age, higher IQ, more years of education, higher MMSE, faster gait speed, and higher GDS to be potential effect modifiers."

"Virtual and augmented reality (VR / AR) applications have successfully overcome the critical part of the Gartner curve. Investments are made and new products entering the economy. However, a very small percentage of society have also heard about AR glasses, mainly linking these with potential identity threats and personal data breaches. The authors dealt with the design of application of AR to improve golf skills by improving the putting technique. The above solution is complicated by requiring complex object recognition, tracking and advanced AR software designing."

Dislexia: um estudo de caso com possibilidades de intervenção pedagógica
Authors: Amaral Marco Antônio Franco do , Silva Moura Sabrina , Mendonça Fernanda Fátima Mendes , Sousa Géssica Alves de
Published: March 2021

A dislexia é uma dificuldade de aprendizagem muito presente no ambiente escolar e tema de recorrentes discussões que pode ser diagnosticada tanto na infância quanto na vida adulta. O presente artigo é oriundo de uma pesquisa qualitativa e bibliográfica que se inicia com um estudo teórico descrevendo posteriormente um estudo de caso. Ele tem como objetivo entender e analisar possíveis estratégias para ajudar um aluno disléxico, demonstrando aos educadores diferentes métodos para compreender suas capacidades e necessidades, chegando assim a uma definição de dislexia, suas causas e quais sinais são demonstrados pelo educando que podem ajudar a diagnosticar o transtorno. Observando que a dislexia é um distúrbio de aprendizagem e não uma doença e se diagnosticada no início os resultados de possíveis intervenções podem obter mais sucesso, ou seja, o indivíduo vai melhorar o processo de ensino e aprendizagem mais facilmente, concluímos que se faz necessário o apoio da família em conjunto com a escola que deve orientar seus profissionais a desenvolver metodologias de ensino que possibilitem maior desenvolvimento do aluno.
