TO BE OR NOT TO BE A PLATFORM WORKER? LITHUANIAN CASE IN THE CONTEXT OF EU COUNTRIES
Authors: Miežienė Rasa , Blažienė Inga , Gruževskis Boguslavas
Published: December 2022

The first wave of the COVID-19 pandemic, which peaked in 2020, and the unprecedented demand for home delivery services have led to the growth of platform work in many countries all over the world. The article analyses the situation of platform workers in the Lithuania’s labour market in the context of other EU countries. The paper presents the findings of a survey of platform workers carried out to define the social-economic picture of platform workers and identify their attitudes towards platform work in Lithuania. The survey has shown that the labour market situation of platform workers in Lithuania follows trends similar to other European countries in terms of socio-demographic characteristics, preferences and challenges. Slightly more significant differences between EU countries and Lithuania can be observed when analysing platform workers’ working time and earnings.

Published: December 2022

The impact of geometric characteristics on traffic risk is reflected through identifying conflict points on roads,traffic accidents, and any other unforeseen situation that is inherently hazardous for traffic participants. In order to identify the road sections with the highest risk, it is necessary to consider a number of criteria that affect risk, and conduct extensive empirical research, analysis and data synthesis. This paper evaluates 9 sections of two-lane roads in the territory of Bosnia and Herzegovina (the Republic of Srpska) using an integrated Multi-Criteria Decision-Making (MCDM) model.To determine the significance of 8 criteria for the evaluation of the sections, it was applied a subjective–objective model consisting of 3 methods: (1) CRiteria Importance Through Inter-criteria Correlation (CRITIC), (2) FUll COnsistency Method (FUCOM) and (3) fuzzy PIvot Pairwise RElative Criteria Importance Assessment (PIPRECIA). The aggregation of the criterion values obtained using the methods yielded the final criterion values. Measurement Alternatives and Ranking according to COmpromise Solution (MARCOS) method was used to evaluate the sections and determine their objective diversity. The obtained results identified one location as extremely hazardous by most of analysed input parameters. The section with the highest risk is the Rudanka – Doboj section (A4), which represents a section of the road infrastructure of the 105 road. The validation of the results obtained by applying the integrated MCDM model was performed through an extensive sensitivity analysis. The weights of criteria were observed through initially individual methods implemented in the MARCOS method. Then, a comparative analysis was performed with 6 other MCDM methods and Spearman’s Correlation Coefficient (SCC) was calculated as a statistical indicator of rank correlation in a sensitivity analysis. In addition,the Standard Deviation (STDEV) of the obtained results was determined.
Polytropic Behavior in the Structures of Interplanetary Coronal Mass Ejections
Authors: Dayeh M. A. , Livadiotis G.
Published: December 2022

The polytropic process characterizes the thermodynamics of space plasma particle populations. The polytropic index, γ, is particularly important as it describes the thermodynamic behavior of the system by quantifying the changes in temperature as the system is compressed or expanded. Using Wind spacecraft plasma and magnetic field data during 1995 February–2015 December, we investigate the thermodynamic evolution in 336 interplanetary coronal mass ejection (ICME) events. For each event, we derive the index γ in the sheath and magnetic ejecta structures, along with the pre- and post-event regions. We then examine the distributions of all γ indices in these four regions and derive the entropic gradient of each, which is indicative of the ambient heating. We find that in the ICME sheath region, where wave turbulence is expected to be highest, the thermodynamics takes longest to recover into the original quasi-adiabatic process, while it recovers faster in the quieter ejecta region. This pattern creates a thermodynamic cycle, featuring a near adiabatic value γ ∼ γ

after the passage of the ICME. These results expose the turbulent heating rates in the ICME plasma: the lower the polytropic index from its adiabatic value and closer to its isothermal value, the larger the entropic gradient, and thus, the rate of turbulent heating that heats the ICME plasma.

Published: December 2022

We report optical and near-infrared spectral characterization of an M dwarf companion to the bright F2 star μ Virgenes. Data from Shane/Kast and IRTF/SpeX yield identical spectral types of M5, and spectral features indicate solar metallicity ([Fe/H] = −0.05 ± 0.20) with no evidence of low surface gravity features at optical or near-infrared bands. Strong Hα emission (

Both metallicity and age estimates of the companion are consistent with its primary. As a well-resolved companion to an exceptionally well-characterized bright star, μ Virgenes B serves as a useful benchmark at the transition between partially and fully convective stars.
Small Magellanic Cloud Field Stars Meddling in Star Cluster Age Estimates
Authors: Piatti Andrés E.
Published: December 2022

I revisited the age of the Small Magellanic Cloud (SMC) cluster HW 42, whose previous estimates differ in more than 6 Gyr, thus challenging the most updated knowledge of the SMC star formation history. I performed an analysis of number stellar density profiles at different brightness levels; carried out a field star decontamination of the cluster color–magnitude diagram; and estimated the cluster fundamental parameters from the minimization of likelihood functions and their uncertainties from standard bootstrap methods. I conclude that HW 42 is a

In Malaysia, our knowledge of freshwater ecosystem and its aquatic inhabitants, particularly freshwater fish, remains inadequate, even in protected regions. It is essential to understand the composition of freshwater fish, their distribution along river gradients, and their interactions between environmental variables to develop and strategize effective conservation and management plans. Consequently, an investigation into freshwater fish assemblages in three rivers draining off from the western part of Endau-Rompin Landscape was conducted in 12 established substations. Sampling sessions were conducted from September to December 2021 in the Labis district of Johor, using multiple sampling methods along 200 meters for each substation. The environmental variables were measured using water quality parameters. A total of 66 species were collected. The family Cyprinidae presented the highest species diversity (17 species), constituting 52% of total capture. Crossocheilus obscurus was the most dominant species, and the highest species richness was recorded in the Segamat River (45 species), followed by Juaseh (36 species) and Labis River (34 species). It was discerned that the composition of fish varied between the substations. The knowledge presented here is the first documentation on the freshwater fish from these rivers. It would serve as a baseline information for key authorities and stakeholders to conserve the biodiversity inhabiting freshwater ecosystems in Malaysia.

Published: December 2022

Gastrochilus heminii (Orchidaceae), a new orchid species from Sichuan Province, Southwest China, is described and illustrated. It morphologically resembles G. affinis and G. yei, but differs markedly from the former in having a thinner and slightly rolled downwards reniform epichile and the central thickened purple-red mat with irregular folds (vs. subtriangular epichile curves upwards, with 2 thick, brown to purplish-brown median ridges from base to apex), and can be clearly distinguished from the latter by having reniform epichile with lobed apex and subconical hypochile with bilobed apex that splits into two conical protrusions (vs. semi-rounded epichile not lobed and subconical hypochile not bilobed). The results of molecular phylogenetic analysis based on nuclear ribosome internal transcribed spacer (nrITS) and four chloroplast DNA fragments (matK, psbA-trnH, psbM-trnD, and trnL-F) of 36 Gastrochilus species showed that G. heminii was closely related to G. affinis and G. distichus.
Le régime rentier en Russie et son évolution après la guerre en Ukraine
Authors: Faudot Adrien , Rossiaud Sylvain
Published: December 2022

À la suite du déclenchement de la guerre en Ukraine, l’objectif affiché par l’Union européenne est d’assurer une déconnexion énergétique avec la Russie. De nouvelles interdépendances énergétiques internationales se dessinent en conséquence. À cet égard, l’une des ruptures principales pourrait être la fragmentation des relations énergétiques internationales. Avec toutes les précautions qui s’imposent dans le contexte actuel d’incertitude radicale, cet article questionne la nature et la portée de ce changement structurel, ainsi que ses implications potentielles sur le régime d’accumulation rentier en Russie. Pour ce faire, l’approche institutionnaliste et historique de la théorie de la régulation (TR) est privilégiée. Nous retraçons donc la trajectoire d’intégration internationale de l’industrie pétrolière russe, et l’enracinement du mode de régulation rentier dans ce pays. L’analyse des inflexions observées à la suite de la première crise ukrainienne de 2014 permet de mettre en exergue les mécanismes adaptatifs intégrés dans le mode de régulation de l’industrie pétrolière et, plus globalement, du régime d’accumulation.

Souveraineté technologique ou isolement ? Conséquences de la guerre en Ukraine sur le secteur russe du numérique
Authors: D. Volkov Dmitry
Published: December 2022

À travers l’analyse de l’évolution du secteur russe du numérique, cet article postule que l’invasion russe de l’Ukraine, les sanctions qui en ont résulté et le retrait des entreprises technologiques étrangères ont renforcé certaines des tendances qui ont caractérisé les relations État-marché du secteur depuis trois décennies. L’une de ces tendances a été le renforcement des éléments néoprébendiers du système capitaliste russe, devenant un facteur important dans le choix des stratégies des acteurs du marché adoptées en fonction de leur marché cible (international ou national), de leur stratégie client (B2B, B2C, PME ou grande firme) et de leur spécialisation produit. Une autre conséquence importante du conflit a été la rupture des cycles d’apprentissage et de sélection des entreprises russes du numérique, ce qui risque d’avoir un impact négatif sur le développement technologique du pays en raison des changements dans l’accès aux technologies modernes et dans les sources dominantes de financement et de demande.

Arménie, Géorgie, Azerbaïdjan et la guerre en Ukraine : les dividendes de l’ambiguïté
Authors: Cordonnier Christophe , Vercueil Julien
Published: December 2022

Les trois républiques du Sud-Caucase sont indirectement mais significativement touchées par la guerre en Ukraine. Du fait des conflits qui les traversent, elles ont abordé cette crise internationale en ordre dispersé. Toutefois, malgré des structures économiques très dissemblables, ces trois pays ont adopté des positions diplomatiques similaires vis-à-vis du conflit, maintenant une ambiguïté qui leur a permis d’éviter de pâtir de manière excessive de ses conséquences sur les approvisionnements en matières premières stratégiques. Si l’inflation s’est maintenue ou accélérée en 2022, ces économies ont poursuivi une trajectoire de croissance entamée en 2021, nourrie par leur position géographique favorable qui leur permet de servir de refuge aux populations russes fuyant le régime et la guerre, mais aussi de plaque tournante logistique et commerciale à l’échelle de la région. L’enjeu pour le moyen terme sera de maintenir cette position d’équilibre instable entre Russie, Union européenne et Turquie. Classification JEL : F24, F32, F51, O53.
La guerre en Ukraine : choc géopolitique régional et global
Authors: Kastouéva-Jean Tatiana
Published: December 2022

Limitée (pour l’instant) militairement au territoire de l’Ukraine, la guerre déclenchée par la Russie le 24 février envoie des ondes de choc géopolitiques bien au-delà des deux protagonistes du conflit militaire. Ce choc frappe à la fois les anciennes républiques soviétiques et les pays européens, en les poussant à réduire leurs dépendances à la Russie et à redéfinir les lignes directrices qui ont longtemps guidé leurs politiques étrangères. Au-delà de ce périmètre à l’ouest et au sud des frontières russes, certains pays semblent tirer des bénéfices de cette guerre à court terme comme, par exemple, la Chine ou l’Inde qui peuvent acquérir du gaz et du pétrole russes à prix « cassés ». Cependant, même pour ces pays, la remise en cause de l’ordre international comporte de nombreux risques ; certains s’annoncent difficilement maîtrisables dans un monde plus fragmenté où même la dissuasion nucléaire ne semble plus garantir la stabilité.

Published: December 2022

Aujourd’hui, les besoins en veille collaborative et l’interfaçage avec des réseaux sociaux d’entreprise sont devenus essentiels : l’information a d’autant plus de valeur qu’elle est partagée, visible et valorisée. Mais beaucoup de services de veille fonctionnent encore sur un modèle rigide, plus vertical qu’horizontal, avec des contenus faiblement personnalisés. Les plateformes de veille elles-mêmes induisent aussi parfois des freins fonctionnels. Beaucoup essaient de remédier à cela en proposant cette dimension d’interfaçage et de collaboration. Nous proposons ici un grand tableau comparatif.

Explorer les zones sensibles avec les pratiques artistiques
Authors: Sérusclat-Natale Maud
Published: December 2022

En France, de nombreux dispositifs encouragent les enseignants et les artistes à travailler ensemble dans la continuité d’une politique culturelle et éducative construite de longue date. Pourtant, accueillir un artiste en classe ne va pas de soi, même dans une logique de co-construction de projet et à l’heure de l’avènement d’une pédagogie du sensible. Cette dynamique, ou cet « ébranlement » selon le mot de l’artiste Darren Roshier, est d’autant plus sensible lorsque la résidence artistique se conduit en lycée, dans une temporalité proche des examens, et auprès d’adolescents allophones primo-arrivants soumis à de fortes pressions sociales et scolaires pesant sur leur apprentissage de la langue française. L’étude pose alors la question des rôles que peuvent jouer les artistes et l’importance des expériences artistiques menées dans ce cadre. Elle interroge également les conditions et la manière dont ces expériences peuvent dépasser les traditionnels débats dans ce « détour » par les arts.
Quand l’enseignant « bricole » : une adaptation entre inconscience et rationalité
Authors: Alvarez Dominique , Cadiou Sandra , Mothes Patricia
Published: December 2022

Dans son quotidien professionnel, l’enseignant doit faire face à une multitude d’imprévus et s’adapter constamment. Nous observons la dimension inconsciente du bricolage. Notre travail s’appuie sur trois vignettes didactiques cliniques. Ces trois cas exposés rendent compte de la dimension inconsciente de leur adaptation qui serait pilotée par leur déjà-là et des motifs variés de cette adaptation. Entre impossible à supporter, sujet supposé savoir et maintien de l’espace psychique de la classe, divers concepts issus d’une orientation psychanalytique nous permettent de saisir davantage les processus du bricolage inconscient, et nous donnent des orientations pour la formation des enseignants.

Racismo obstétrico em Portugal : Relato de experiência de um coletivo antirracista
Authors: Costa Karla Adriana Oliveira da , Brito Laura Elisabete Figueiredo , Coimbra Carolina Vanessa da Silva , Lopes Ninfa Carina Costa , Depuydt Diana Oliveira dos Santos , Correia Rita Nunes
Published: December 2022

A violência obstétrica é uma violência de gênero, que tem o racismo como sobreposição, tornando as mulheres negras mais vulneráveis. Em Portugal, esta realidade continua silenciada por detrás do mito da igualdade social difundido no pós-período colonial. Os corpos destas mulheres no cenário obstétrico no país trazem-nos a necessidade de abordar questões de corpo-raça-saúde articuladas com os movimentos feministas e negros. Este artigo parte de uma abordagem teórica sustentada nos estudos pós-coloniais e feministas, com uma perspectiva sociológica. Em termos metodológicos, o texto compartilha as atividades de um coletivo de mulheres antirracistas sob uma perspectiva interseccional, utilizando a técnica metodológica do relato de experiência. Os principais resultados deste estudo apontam para a pertinência de se desenvolver uma investigação sociológica transversal sobre as experiências de saúde reprodutiva das mulheres racializadas em Portugal e a importância dos movimentos sociais para a realização desses trabalhos. O coletivo Saúde das Mães Negras (SaMaNe), através de quatro frentes de atuação, traz para o debate social, político e académico as experiências de gravidez, parto e pós-parto de mulheres negras e afrodescendentes em Portugal. Concluiu-se que há necessidade de aprofundar o debate sobre as opressões e desigualdades raciais nos cuidados obstétricos, pelo que este artigo pretende também romper com o silêncio em torno do tema e transformá-lo em ação.
Chinese EFL Teachers' Perceptions of Subtitles' Effects on English Comprehension and Vocabulary Acquisition
Authors: Xu Yilan , Jordan Eoin , Li Yuanzhe
Published: December 2022

This article reports on a qualitative study that evaluated Chinese EFL (English as a Foreign Language) teachers' perceptions of the effects of four different subtitling modes on English comprehension and vocabulary acquisition of learners in secondary education. The four types of subtitles refer to no subtitles, Chinese subtitles, English subtitles, and bilingual subtitles in audiovisual materials. The results of the study indicated that interviewees regarded the use of no subtitles as the least effective of the modes for enhancing students' language proficiency. Chinese subtitles were perceived to assist students with comprehension of content but were less effective at enabling them to recall and memorize English lexis. English subtitles were perceived to aid comprehension of the content to some degree, while also inspiring learners to develop their English vocabulary knowledge. Bilingual subtitles were considered to enhance both students' English comprehension and vocabulary acquisition.
Factors of Innovation Management Transformation in Digital Innovation Ecosystems of Russian Companies
Authors: Khachaturyan Mikhail , Klicheva Evgeniia
Published: December 2022

Digital innovations are becoming increasingly important both in the global and in the Russian economies. It is also obvious that most types of innovations, both traditional and digital, are developed not within the framework of one organization, but in digital innovation ecosystems that unite several organizations and various stakeholders related to entrepreneurship, such as universities, research centers, business associations, industrial and infrastructure institutions. The data obtained in the process of studying the features of the formation and development of leading Russian innovation centers was used as a practical basis for the study. As a result of the study, the authors were able to identify four groups of factors influencing the transformation of innovation management within the digital innovation ecosystems of Russian companies.
Levelling Up Language Learning
Authors: Vallorani Cecilia Maria , Gibert Isabel , Tuffnell Christopher
Published: December 2022

This study examines the use of gamification as an innovative assessment approach to foreign language learning with 12–14-year-old students. A mixed methodology has been applied. Quantitative data have been collected from formative non-gamified and gamified assessments. Qualitative data was collected from a student questionnaire. The results were obtained from an international middle school where four groups of students, two in Grade 7 and two in Grade 8, engaged with gamified formative assessment. Findings show that gamification can provide a useful support mechanism in assessment success, and also on an emotional level as it lowers the affective filter, allowing the students to reduce potential anxiety and face the assessment with greater confidence. However, gamification had a small negative impact on otherwise high-performing students in the study, suggesting that gamification may not be appropriate in all contexts.
The Innerworkings of Digital Storytelling
Authors: Daniels André David , Venter Isabella Margarethe
Published: December 2022

Traditionally, storytelling was used for entertainment and the transfer of know-how. The advent of digital media gave rise to new possibilities for telling stories. When the context is, for example, to relay information about how to protect a person from COVID-19, it is referred to as serious storytelling. The main objective of this research was to establish what skills and attributes would be required for someone to autonomously “tell” a serious digital story in a resource constrained environment. A systematic literature review of peer reviewed articles resulted in a knowledge bank of articles. Atlas Ti was used to qualitatively analyse these articles. Even though a resource constrained environment may be a limiting factor for telling a digital story, this research has found that emotional support, digital inclusion, as well as assisting individuals with their devices, can pave the way to autonomous digital storytelling.
Being “Badass”
Authors: Kramer Brianne N.
Published: December 2022

This article focuses on a case study of the Badass Teachers' Association, the largest nationwide teacher activist organization in the United States. The theoretical framework of social movement theory and community organizing provides a structure upon which to better understand the organization. Ten members of leadership participated in this study, which utilized a series of three interviews focusing on different aspects of leaders' beliefs and the role of the organization, while document analysis provided historical context for the development and evolution of the organization. Two themes—strength of identity and role of the organization—were found in the analysis of the data. The importance of the organization in furthering teachers' voices and expanding the organization's influence is discussed in the findings.
Leader Deception and Ethical Decision-Making
Authors: Stenmark Cheryl
Published: December 2022

Sensory processing sensitivity (SPS) is a trait that refers to a person's sensitivity to stimuli, ambiguity, and stressful environments. The present study examined the effects of SPS and leader deception on ethical decision-making. Participants completing a scenario-based ethical decision-making task were given information within the task that their hypothetical leader was honest or deceptive. Results revealed that people higher in SPS who had an honest leader made significantly better decisions than both 1) people higher in SPS with a deceptive leader and 2) people lower in SPS in general. Results suggest that for people higher in SPS, cognitive processing may be disrupted by leader deception, so ethics interventions should help them to learn techniques or use cognitive tools to overcome the disruption.
Future Leaders' Ethical Behavior Development Using Boricua College's Affective Development Model
Authors: Goods Alfreda
Published: December 2022

Business students have witnessed a decline in moral and ethical leadership in organizations, as reported by the media. Even though there has been increased awareness, unethical leadership continues to rise, requiring the need to slow the progression of future business leaders' tendency to be unethical by training them to develop ethical value systems as undergraduates. Although there is much debate about whether business students should receive ethical training, the main issue is its teaching. The researcher in this study explores developing students' affective domain using the Boricua Colleges' Business Administration Differentiation of Personal and Professional Values course. The course focuses on students developing their mental and emotional states by deconstructing the constructs of ethics to develop ethical value systems. The researcher explored this course as a possible link to address what is missing from the Business Administration curriculum to support developing ethical business students in their behaviors and decision-making.

Health centers, in recent times, are being considered as important resources to take care of people's health, with greater importance with the arrival of the pandemic produced by COVID-19, where one of the main concerns was to be able to increase their medical equipment. These actions are very helpful, but in some cases, the requirement on the consumption of electrical energy is ignored, which can cause a decrease in voltage levels, which would cause a malfunction of the medical equipment and current surges, which would lead to much of the equipment connected to the electrical network being affected. The proposed methodology is based on being able to monitor and evaluate the consumption of electrical energy, organized under an IoT network configuration, to measure by areas and by critical services that may be affected, and to measure the current and voltage at each critical point. To test the methodology, current and voltage sensors will be used. As an IoT interface, the 16-bit PIC-IoT, a module, was made in LabVIEW to monitor and evaluate the measurements.
CODVerif
Authors: Khalfallah Malik , Ghodous Parisa
Published: December 2022

CODVerif is an approach that aims to verify the data being inserted in a data store continuously. CODVerif leverages the combination of ontology and workflow technologies in order to define workflows that are specific to the domain of “monitoring data insertion.” These domain-specific workflows are constrained on two dimensions: (1) They use a set of workflow elements that are specific to the “monitoring data insertion” domain. (2) The logic that these workflows support is predefined by relying on a set of common data insertion scenarios. Nevertheless, CODVerif is flexible enough to allow users to define continuous data verification workflows with higher complexity logic thanks to workflow operators that can be applied on the “monitoring data insertion domain”-specific workflows. To illustrate the applicability of CODVerif, the authors deploy it in a customer relationship management (CRM) application and show how CODVerif is used to support users to verify the data they populate in the CRM. They have also evaluated the CODVerif approach.
Improving Operational Efficiency in Radiology Using Artificial Intelligence
Authors: Ambay Raj S. , Jabbari Korosh M. , Goel Piyush , Patel Shamit V. , Kedar Rajendra P.
Published: December 2022

New developments in information technology are revolutionizing healthcare operations by providing new ways to optimize operational efficiency and reduce costs. Among the methods are artificial intelligence, machine learning, agile methodologies, and robotic process automation. These systems can improve operations by learning from past data to predict future trends, avoid pitfalls, and automate repetitive, mundane tasks. This study measured the impact of using an AI-based algorithm within a multi-center radiology practice to increase operational efficiency by predicting and filling unutilized capacity which reduces patient wait times. The study was conducted over 31 weeks and demonstrated a 71% reduction in patient wait time from 7 days to 2 days and a 6% increase in the utilization of CT and MRI machines with no increase in workload for the scheduling staff or the working hours of the operational staff. While this study has limitations, standards for AI-based algorithms in healthcare are needed to reduce bias, improve equity, and establish trust in this technology.

Published: December 2022

Context:

Effects of coronavirus disease 2019 (COVID-19) pandemic lockdown on road traffic accidents (RTAs) in Chhattisgarh, India.

Background:

Most neurosurgical emergencies are from brain and spine trauma. RTA is the leading cause of such injuries. While the nationwide lockdown was an extreme measure to control the COVID pandemic, it influenced the overall road traffic dynamics and neurotrauma.

Objective:

This study aims to assess the impact of the lockdown on neurotrauma.

Methods and Materials:

This retrospective study included all patients with brain and spine injuries who were admitted between January 17th and May 31st, 2020. The study population was divided into prelockdown (PL) and lockdown (L) groups.

Results:

Of the 668 patients, 436 were placed in the PL and 232 in the L group. The mean ages were 36.34 (SD = 17.96) and 35.98 (SD = 16.93), respectively. Male to female ratios were 82.3:17.7 in the PL group and 79.7:20.3 for the L group. RTA-related injuries were significantly lower during the lockdown period (n = 335 PL vs. 162 L [P = 0.048]). During the lockdown, there were more mild injuries (25.91% PL vs. 36.63% L) and less severe injuries (33.25% PL vs. 18.96% L [P = 0.0002]). Mortality was significantly less (P = 0.029) during the lockdown (n = 48 L vs. 124 PL). The proportion of RTA-related neurotrauma cases increased (33.33% L1, 57.14% L2, 73.13% L3, and 80.39% L4) with each phase of lockdown (L1-L4).

Conclusions:

During the lockdown period, the number of trauma cases had decreased, with a significant decrease in RTA-related admissions, along with their severity and mortality. The number of trauma cases and their severity increased gradually with each phase of lockdown.

Authors: Hamamcı Mehmet , Küçük Bekir , Bayhan Seray A , Bayhan Hasan A , İnan Levent E
Published: December 2022

Background:

In this study, we aimed to evaluate the association of lamina cribrosa thickness (LCT) and lamina cribrosa depth (LCD), as determined by spectral domain optical coherence tomography (SD-OCT), with visual evoked potentials (VEPs) in patients with multiple sclerosis (MS).

Materials and Methods:

Patients enrolled in this prospective, cross-sectional study were divided into three groups. Group 1 consisted of 25 relapsing-remitting MS patients with VEP pathology in one or both eyes. In patients with VEP pathology in both eyes, one eye was chosen randomly. Group 2 comprised 25 relapsing-remitting MS patients with no VEP pathology or optic neuritis history. A randomly selected single eye of each patient was evaluated. Group 3 consisted of 25 age- and sex-matched healthy volunteers; a randomly selected single eye of these participants was examined. LCT, LCD, and retinal nerve fiber layer (RNFL) thickness measurements were determined in four quadrants (superior, inferior, nasal, and temporal) by SD-OCT.

Results:

The three groups were similar in terms of age and sex. The mean LCT was lower in Group 1 than in Group 2, but the difference was not statistically significant (268.80 ± 36.69 μm [min-max = 222-394 μm] versus 285.80 ± 12.00 μm [min-max = 249-338 μm]; P = 0.148). The mean LCT was significantly lower in Group 1 than in Group 3 (268.80 ± 36.69 μm [min-max = 222-394 μm] versus 294.80 ± 12.00 μm [min-max = 232-351 μm]; P = 0.012). There was a weak positive correlation between LCT and RNFL-inferior, RNFL-nasal, and RNFL-temporal.

Conclusion:

We found that the lamina cribrosa was thinner in MS patients with VEP pathology. To the best of our knowledge, this is a novel finding. Our results imply that LCT could be used as an indicator of optic neuritis in MS patients.

Authors: Kanikannan Meena A , Reddy Pavan K , Mathukumalli Neeharika L , Yareeda Sireesha , Borgohain Rupam
Published: December 2022

Background:

Thymectomy, combined with corticosteroids, immunosuppressive agents, and cholinesterase inhibitors, has been accepted as the standard treatment for myasthenia gravis (MG) patients. Data on the effect of thymectomy on occurrence of myasthenic crisis are few.

Objectives:

To assess the long-term impact of thymectomy in patients with generalized Myasthenia gravis (GMG) in terms of occurrence of myasthenia crisis and quality of life.

Methods:

A retrospective analysis of 274 clinical records of patients diagnosed with myasthenia gravis (MG) in Nizam's institute of medical sciences (NIMS), a tertiary level teaching hospital between January 2000 and December 2015 was done. Severity of the disease was assessed using Myasthenia Gravis Foundation of America (MGFA) classification and quantitative myasthenia gravis (QMG) score. Myasthenia crisis was diagnosed in our patients when they required ventilator assistance due to respiratory failure caused by muscle weakness (MGFA class V). Quality of life (QoL) was assessed.

Results:

Of 230 cases included in the final analysis, 108 (46.9%) underwent thymectomy. Posttreatment crisis occurred in 53.3% of the nonthymectomy subjects, and 25.9% of thymectomy group (P < 0.001). In multivariate logistic regression analysis, after controlling for the effect of gender, age at diagnosis and grade of the disease, the odds ratio of myasthenic crisis in people with thymectomy was 0.186.(95% CI 0.087 to 0.387, P = 0.001). No statistically significant differences were observed in quality of life scores between thymectomy and nonthymectomy groups, either before (P = 0.86) or after surgery (P = 0.939).

Conclusions:

The odds of myasthenia crisis was lesser in people, who underwent thymectomy even after controlling for MGFA grade and other potential confounders but no significant differences in quality of life were found with thymectomy.

Authors: Nagappa Madhu , Wahatule Rahul , Bindu Parayil S. , Sinha Sanjib , Taly Arun B.
Published: December 2022

Background:

Sensory nerve conduction parameters in Guillain Barre Syndrome (GBS) are underemphasized.

Objective:

To describe abnormalities on sensory conduction studies in a large cohort of prospectively evaluated patients of GBS and to correlate with clinico-electrophysiological features.

Methods and Materials:

Sensory conduction parameters of three nerves (median, ulnar, and sural) were analyzed using standard protocols in 238 patients (M: F 163:75, mean age: 35.76 ± 15.9 years). Electrophysiological subtyping was based on criteria of Hadden et al., and Rajabally et al.

Results:

Among patients with “typical” GBS who underwent electrophysiological testing within 30 days of symptom-onset (n = 219), 183 (83.5%) had abnormal sensory potentials (one nerve = 52, two nerves = 77, all three nerves = 54). Frequency of abnormalities in sensory potentials increased with duration of illness. Commonest abnormality was reduced amplitude or in-excitable nerves. Mean amplitude and velocity of median and ulnar nerve sensory potentials were significantly lower among those with demyelinating electrophysiology (P < 0.05). Proportion of subjects with reduced amplitude and velocity of median and ulnar nerve sensory potentials was higher among those who required mechanical ventilation (P < 0.05). Frequency of “sural sparing” ranged from 10.5% to 84.5% depending on the criteria used and almost always was significantly associated with demyelinating neuropathy.

Conclusion:

This prospective study provides comprehensive data on sensory conduction parameters in GBS. Abnormalities are frequent and vary with duration of illness. While median nerve is most frequently and more severely affected, involvement of sural nerve may have prognostic value.
Timing of Surgery for Ruptured Arteriovenous Malformations with Intracerebral Hemorrhage
Authors: Aggarwal Varun , Rohilla Seema , Singh Ishwar , Pandey Vardan , Krishna Gopal
Published: December 2022

Background:

Both early surgery and delayed surgery of ruptured arteriovenous malformation (AVM) with intracerebral hemorrhages have their own advantages and disadvantages. Due to lack of large case–control studies, timing of surgery for ruptured AVM excision is still a controversial topic. So, we did a systemic review and meta-analysis, including our experience of early surgery, to see which surgical strategy has a favorable outcome.

Materials and Methods:

We systematically searched several databases and journals to screen eligible studies. After synthesizing data, results of individual studies of early and delayed surgery were calculated as the effect size (ES) and 95% confident intervals (CIs), and the pooled ES was calculated using random-effects model. Heterogeneity and publication bias were assessed for the individual outcomes.

Results:

A total of nine published studies, one oral presentation, and our unpublished study were included in the analysis. Delayed surgery has better results than early surgery in terms of complete excision rate (delayed ES, 1.00; 95% CI, 0.97 1.00 vs. early ES, 0.96; 95% CI, 0.91 0.99), good functional outcome (delayed ES, 0.94; 95% CI, 0.86 0.99 vs. early ES, 0.68; 95% CI, 0.51 0.84), and mortality (delayed ES, 0.00; 95% CI, 0.00 0.01 vs. early ES, 0.04; 95% CI, 0.01 0.10). Heterogeneity was significant in the results of early surgery group, and no publication bias was found in the meta-analysis.

Conclusion:

Delayed surgery is superior to early surgery in achieving higher complete excision rate, good functional outcome, and reducing mortality. However, larger comparative studies are needed for subgroup analysis and for reducing the impact of various confounding factors.
Nutrition Management Across the Stroke Continuum of Care to Optimize Outcome and Recovery
Authors: Holdoway Anne , Arsava Ethem Murat , Ashford Stephen A. , Cereda Emanuele , Dziewas Rainer , Francisco Gerard E.
Published: December 2022

Stroke and the resulting long-term disability impose a substantial socio-economic burden. Stroke survivors have nutritional challenges at many stages along their care pathway, and the role of nutritional therapy and medical nutrition in stroke recovery is often overlooked. Appropriate nutrition is a prerequisite for optimizing short-term outcome and recovery from stroke and should be integral across the continuum of care, with management intervention if needed. Nutrition should be reviewed as part of the care for all people post-stroke. If nutrition support is required, it should be initiated at the acute phase and adjusted according to the ability to eat and drink throughout the care pathway. A range of complications arising post-stroke including malnutrition, dysphagia, sarcopenia, and pressure injuries can be prevented or improved by timely appropriate nutritional therapy. This also improves physical and mental function, increases strength and mobility which facilitates effective neurorehabilitation, reduces the risk of infection and pressure injuries, promotes wound healing, and improves the quality of life. An appropriately trained nutrition specialist or dietitian should assess and monitor the individual, but all members of the multidisciplinary team have a role in delivering, monitoring, and supporting the nutritional status and changing needs of the stroke survivor. This review by authors from multidisciplinary fields in stroke care is a consensus based on serial, open discussion meetings. The review explores the interrelationship between malnutrition, sarcopenia, nutrition, and pressure injuries, and seeks to raise awareness among all health professionals who manage the stroke survivor, of the supportive role of nutritional therapy.

Published: December 2022

Background:

Pancreatic ductal adenocarcinoma (PDAC) is the most devastating of all cancers with an extremely poor prognosis. It has few effective and reliable therapeutic strategies. Telmisartan, a widely used antihypertensive drug, is an angiotensin II type 1 (AT1) receptor blocker (ARB). Telmisartan inhibits cancer cell proliferation, but the underlying mechanisms in PDAC, remain unknown.

Material and Methods:

In the present study, we evaluated the effects of telmisartan on human PDAC cell proliferation in vitro. We assessed the effects of telmisartan on human PDAC cells using the cell lines PK-1 and PANC-1.

Results:

Telmisartan inhibited the proliferation of these cells via blockade of the G0 to G1 cell cycle transition. This was accompanied by a strong decrease in cyclin D1. Telmisartan was also shown by receptor tyrosine kinase and angiogenesis arrays to reduce the phosphorylation of epidermal growth factor receptor (EGFR), and miRNA expression was markedly altered by telmisartan in PK-1 cells.

Conclusion:

In conclusion, telmisartan inhibits human PDAC cell proliferation by inducing cell cycle arrest. Furthermore, telmisartan significantly altered miRNA expression in vitro. Taken together, our study demonstrated the therapeutic potential of telmisartan and provides molecular mechanistic insights into its anti-tumor effect on PDAC cells.
