Studies of critical heat fluxes in small diameter channels
Authors: Belozerov Vladimir I.
Published: December 2021

The paper presents the results of experimental studies of critical heat flows in vertical small diameter channels, when the coolant moves from bottom to top, which were carried out in the Obninsk branch of MEPhI in the 1970s of the last century but have not become widespread due to the lack of demand for their practical use. Nowadays, the interest in such works is manifested, first of all, in the development of compact plants and devices, particularly in nuclear power engineering.

As a coolant, water, Freon-12 and 96% ethyl alcohol were used. High velocities of underheated liquid at high heat fluxes on the channel wall lead to the so-called “fast crisis” of heat transfer. In this case, the magnitude of the heat flux depends mainly on the parameters of the coolant flow in the wall zone rather than the flow core. The “slow crisis” is mainly observed at high vapor concentrations, relatively low mass flow rates and in an annular-dispersed flow. The value of the critical heat flow in this case depends mainly on the flow parameters in the core, which are probably close to the average coolant flow parameters. The conditions in the near-wall region are also largely determined by the flow in the core. High heat transfer coefficients in a flow moving at high speed usually result in a much smaller and slower rise in the wall temperature. Sometimes a DNB heat flux can occur bypassing the boiling process. In the core of a VVER-type reactor operating in its nominal mode, surface boiling is present in a number of fuel rods. Probably, surface boiling will also be present in transportable and small-size nuclear power plants. Therefore, an important task is to conduct relevant research in this area.

Introduction: The aim of the present study was to research the analgesic activity and effect of new dipharmacophore compounds consisting of substances with proven therapeutic activity, namely nebracetam–ibuprofen (NRIP), nebracetam–dexibuprofen (NRDIP), nebracetam–niflumic acid (NRNFA), and nebracetam–mefenamic acid (NRMFA), on the cognitive abilities of rats.

Materials and methods: The experimental study was performed in 110 Wistar rats (male/female ratio 50/50%), weighing 180–200 g, and 50 laboratory mice (male/female ratio 50/50%) weighing 18–22 g. The study of the analgesic activity was carried out using the acetic acid writhing test and the hot plate test. The effect on the cognitive abilities of rats was studied using the pattern recognition test in a model of neurotrauma caused by a drop-weight.

Results and discussion: It has been shown that the administration of dipharmacophores nebracetam–ibuprofen (NRIP), nebracetam–dexibuprofen (NRDIP), nebracetam–niflumic acid(NRNFA) as well as nebracetam–mefenamic acid (NRMFA) in the tested dosages leads to a statistically significant (p<0.05) analgesic action in acetic acid writhing tests and hot plate tests. At the same time, the analgesic activity of the compounds has been shown to conjoin with a statistically significant influence on cognitive functions in the experimental animal groups after simulating a neurotrauma.

Conclusion: The dipharmacophore compounds studied in the present research, having analgesic and nootropic effects, can be used as effective and safe analgesics and can also be used for the treatment and prevention of pain syndrome, enhancing the cognitive abilities of healthy people in complicated professional conditions.
L’État britannique recomposé par le Brexit
Authors: Le Galès Patrick
Published: December 2021

À la suite de travaux comparatifs sur l’État en Europe, l’article vise à mettre en évidence, interpréter et parfois expliquer les dynamiques de recomposition de l’État britannique liées au Brexit. Elles se combinent avec une décennie d’austérité sévère et la crise de la Covid-19. Le départ de l’Union européenne (UE) pose des questions existentielles à l’État britannique. L’article vise tout d’abord à montrer les conséquences du Brexit sur l’organisation de l’État, ses institutions, son gouvernement et ses politiques car la sortie de l’UE conduit à une « dé-européanisation » de l’État ou, à tout le moins, à un autre type d’européanisation. Deuxièmement, ce processus conduit à une renationalisation de l’autorité politique, une centralisation anglaise aux dépens des périphéries et du système juridique. Le Brexit met enfin à mal la conception britannique de l’État et ouvre la porte aux entrepreneurs politiques conservateurs qui tentent d’esquisser un autre modèle d’État centralisé, anglais, néolibéral et globalisé.
Order... and Disorder
Authors: Rozenberg Olivier
Published: December 2021

Sous une multitude d’aspects, le Brexit a donné à voir la place importante du Parlement britannique. La centralité préservée ou retrouvée de Westminster interpelle la science politique non seulement parce que de nombreux politistes souscrivent, même implicitement, à la thèse de la déparlementarisation mais également parce que les études parlementaires ( legislative studies ) ne sont pas à même de rendre compte des différents registres et logiques d’action manifestés durant la décennie 2010 par les parlementaires britanniques pour faire advenir ou repousser le Brexit. La focalisation sur l’agenda et les commissions des études parlementaires conduit en effet à négliger des éléments importants que peuvent éclairer d’autres secteurs de la science politique, de la sociologie des partis aux relations internationales. Par ailleurs, les séances chaotiques à la Chambre des communes en 2019 offrent une rare illustration de la pertinence de la théorie du choix social et invitent les politistes à s’appuyer sur les cadres conceptuels de l’économie politique pour comprendre, au-delà du Brexit, les multiples formes de dérationalisation à l’œuvre dans les parlements contemporains.

Accuracy of IOL Power Calculation Formulas for Quadrifocal Acrysof IQ PanOptix TFNT Implantation in Patients With Previous Corneal Refractive Surgery: Comparison of SS-OCT–Based Biometers
Authors: Choi Jung Yeol , Choi Ayoung , Kwon Hyunggoo , Jeon Sohee
Published: December 2021

PURPOSE:

To evaluate the accuracy of intraocular lens (IOL) power calculation formulas from two biometers using swept-source optical coherence tomography for quadrifocal Acrysof IQ Panoptix TFNT IOL (Alcon Laboratories, Inc) implantation in patients with visually significant cataract with previous corneal refractive surgery.

METHODS:

This retrospective study comprised 50 eyes from 50 patients with a history of corneal refractive surgery and TFNT IOL implantation. Candidate formulas were Shammas-PL and Barrett True-K in the Argos (Movu, Inc), Barret True-K and Haigis-L in the IOLMaster 700 (Carl Zeiss Meditec AG), and Haigis using the total keratometry (TK) mode in the IOLMaster 700. The main outcome measure was the mean absolute error (MAE) detected at postoperative 6 months. The refractive accuracy was also evaluated as number and percentage of eyes within ±0.25, ±0.50, and ±0.75 diopters (D) of the prediction error.

RESULTS:

The uncorrected distance and near visual acuity were 0.32 ± 0.34 and 0.46 ± 0.20 logMAR at baseline, and significantly improved to 0.04 ± 0.07 and 0.03 ± 0.06 logMAR at postoperative 6 months (
P
< .001 for all analysis) with a mean spherical equivalent of −0.20 ± 0.39 D. The MAE was smallest for the Barrett True-K formula in the IOLMaster 700 (0.36 ± 0.26 D) and largest for the Shammas-PL formula in the Argos (0.59 ± 0.37 D). The Barrett True-K formula from both devices showed that 90% of eyes were within ±0.75 D of MAE.

CONCLUSIONS:

The visual and refractive outcomes of TFNT IOL implantation in patients with previous corneal refractive surgery were favorable. The Barrett True-K formula in the IOLMaster 700 showed the best refractive outcome for TFNT IOL implantation.

Non-linear behavior in building frame structures is inevitable and expected in moderate to severe seismic events. This behavior tends to be concentrated at the ends of beams and columns of moment-resisting frames. These critical regions, where plastic hinges form, are important for the global stability of the structural system. Depending on the available ductility, these mechanisms are responsible for the permanent deformations that the structure undergoes, leaving the remaining parts of the structural elements in the elastic regime, and hence in the safe zone. The importance of these mechanisms led to the search for an adequate model capable of well-capturing the non-linearity phenomena involved. The development of versatile hysteresis models with degradation features has been the aim of different studies. Hence, this paper presents a parametric study based on a smooth hysteresis model, a further modification to the well-known Bouc-Wen model, developed by Sivaselvan and Reinhorn, with a physical interpretation appropriate to the study of the non-linear behavior of civil engineering structures, particularly, building structures. Furthermore, an optimization procedure is implemented to calibrate the mentioned model's parameters, attempting to replicate the actual cyclic response of a reinforced concrete frame structure. The effect of each parameter in the hysteresis response will help on the understanding and on the possibilities of this kind of model in simulating different types of structural systems or different materials.
Un precinto bilingüe de plomo de la conquista omeya de la península ibérica

Published: December 2021

Se presenta un sello de plomo bilingüe árabe-latino, hasta ahora desconocido, que representa un pacto de paz (muṣālaḥa). Las similitudes de los signos latinos de una de sus caras con los encontrados en una emisión monetaria visigoda atribuida a la ciudad de Sevilla nos llevan a sugerir que este sello podría ser de la fase más temprana de la conquista omeya de la península ibérica, y que probablemente alude al primer pacto de paz establecido por Mūsā b. Nuṣayr con dicha ciudad.
Les imaginaires nationaux : cadres des luttes entre partisans de la fermeture et de l’ouverture. Une analyse des espaces politiques français et danois
Authors: Lans Morgan
Published: December 2021

Face à la multiplication des crises socioéconomiques, les États se sont engagés dans un tournant sécuritaire et identitaire, et les partis d’extrême droite ont connu une progression marquante en Europe. Au même moment, pour répondre à la crise de l’accueil, plusieurs mouvements citoyens en faveur des migrants ont vu le jour. Dans cet article, nous avons choisi de nous intéresser à cette dialectique au sein des espaces français et danois. Nous nous demandons dans quelle mesure les partisans de la fermeté et ceux de l’accueil dans ces pays mobilisent des imaginaires communs. Nous verrons que malgré des prises de position antagoniques, les acteurs font référence à des conceptions de la citoyenneté nationale et sociale portées par leur État. Nos observations montrent toutefois que les conceptions civiques de la citoyenneté semblent plus souvent soumises aux luttes discursives que les conceptions ethniques de la nation qui engendrent, dans le cas danois, moins de dissensions normatives. L’histoire nationale d’un peuple homogène apparait ainsi moins sujette aux débats et aux interprétations que l’histoire d’une communauté politique fondée sur des valeurs. Cet article montre finalement que les luttes qui entourent la citoyenneté en éclairent les contours et précisent l’historicité des formations sociales. En ce sens, il devient nécessaire d’insérer plus systématiquement à l’analyse les prises de position d’acteurs en opposition et les luttes définitionnelles qui en découlent.
Les subalternes de l’asile : Pourquoi certains récits sont inaudibles
Authors: Gatelier Karine
Published: December 2021

A partir de l’expérience d’accompagnement de personnes en demande d’asile, particulièrement de la préparation à l’entretien à l’OFPRA, cet article cherche à comprendre pourquoi certains récits restent inaudibles. En plus des constats déjà établis que le récit de l’asile est contraint et empêché par de nombreux obstacles, je montre qu’un corpus de savoir est constitué en amont de la formation du récit de l’asile et parle avant et à sa place. Celui-ci représente une violence épistémique qui dépossède certaines personnes en demande d’asile de leur parole et en fait des subalternes ne pouvant être entendus. L’existence d’une violence épistémique doit questionner nos pratiques de recherche : en effet, la formation d’un savoir hégémonique met les chercheur·es en position de surplomb qui en plus de reproduire les rapports de domination dans les enquêtes conduites, et donc l’ordre établi, pose des biais dans la perception des réalités sociales.
Transmisión, usos y representaciones lingüísticas de lenguas de herencia árabe y amazig entre estudiantes universitarios en Cataluña
Authors: Barrieras Angàs Mònica , Ferrerós Pagès Carla
Published: December 2021

La investigación que presentamos, que se incluye en el ámbito de estudio de las lenguas de herencia y de la planificación lingüística familiar, tiene como objetivo analizar la transmisión de las lenguas de herencia árabe y amazig en Catalunya, en este caso entre los estudiantes universitarios de origen marroquí. La comunidad marroquí es la comunidad de origen extranjero más numerosa y más antigua en Catalunya, y gran parte de los individuos de esta comunidad tiene como primera lengua el amazig (Castellanos, 2019; Badosa i Ferrerós, 2019). Se pretende observar si hay diferencias en la transmisión del amazig, que es una lengua minorizada, respecto al árabe y, en dicho supuesto, si esta diferencia también se manifiesta en la lengua de identificación de los hablantes. Por este motivo, y en caso de transmisión, también se analizarán los usos y las representaciones lingüísticas. Los datos presentados en este estudio se han obtenido mediante un cuestionario con preguntas semicerradas a estudiantes de origen extranjero de la Universitat de Barcelona y se han analizado cuantitativamente. No se pretende hacer una proyección sobre los estudiantes universitarios en general ni sobre la población inmigrante; se trata de una prospección que deberá permitir identificar tendencias y fenómenos interesantes que puedan guiar futuras investigaciones. A la luz de los resultados de la muestra, el artículo evidencia que las lenguas de herencia se transmiten en un porcentaje elevado y que se consignan frecuentemente como lenguas de identificación, en particular el amazig.

Assessing the Social Media Presence and Activity of Major Greek Cities During 2014-2017
Authors: Karamagioli Evika , Staiou Eleni Revekka , Gouscos Dimitris
Published: December 2021

This chapter describes how little is known about how Greek local authorities capitalize on the potential of social media as a communication channel. The authors present the results of following up on a 2014 study assessing major Greek cities' presence on social media at the time. The authors check whether and how Greek cities may have improved their levels of acting and reacting via social media so as to identify eventual positive changes and/or patterns and discuss potential ways to implement comprehensive strategies for social media as civic interaction tools for local governments. A set of 52 major cities all over Greece (administrative capitals of the corresponding prefectures), has been chosen as the research population. Findings show that local authorities are advancing in the exploration of social media for communication with citizens, but have not yet reached a level at which they would use them as catalysts for citizen interaction in order to enhance civic engagement.

Published: December 2021

The relationship between governments and their citizens has changed with the rise of ICTs. Even if these changes can strengthen the active role of society in the control and participation of public administration, there is a risk that this process can increase exclusion especially in developing countries, mainly because a large part of the population does not have access at all times to the facilities and services provided by ICTs. This article describes e-Totem, a software and hardware platform produced to support inclusive e-participation in large cities. It is also described three popular participation initiatives implemented using the platform, from which hundreds of thousands of citizen interactions were obtained from the platform. e-Totem is customized to be inclusive and suitable for use in such a wide variety of scenarios as well as being used by such a significant volume of people.
Citizen Engagement With Open Government Data

Published: December 2021

Citizen engagement with open government data (OGD) can enhance the effectiveness of governments and improve not only the quality of public policy making but also public services provisioning and ability to address societal problems. Although previous research gives insight into citizen's drivers and inhibitors for engaging with OGD, they have not yet been integrated into a single conceptual model. The aims of this study are twofold: 1) to systematically review the literature on individual citizens' drivers and inhibitors for engaging with OGD and 2) to develop a conceptual model of citizen engagement with OGD based on the findings of the literature review. To attain this objective, the authors systematically analyzed 52 papers published in the period 2009-2019. Seven categories of drivers of citizen engagement are identified: citizen's profile, personal, performance-related, economic, social, technical, and political. Three groups of inhibitors are also identified: citizen's profile, technical, and political. This study helps in understanding how the engagement of citizens can be enhanced.

Published: December 2021

Game-based learning is one of the sustainable education methods for future professionals from the higher education learning environment. To attain these innovative and sustainable teaching pedagogies, the components of games and simulations need to be incorporated into the teaching-learning content. The integration of neuroscience and cognitive concepts has become an essential feature in understanding various phenomena in game-based learning with regard to higher education learning environments. Several neural and cognitive processes are involved while engaging in such activities. These activities have played a pivotal role in the pedagogy and teachers had to think on their feet while engaging students in higher education as well. Game-based learning has proven to be a very effective method of engaging higher education students.

Published: December 2021

Game-based pedagogies use games for achieving learning outcomes by guiding the learners through specific tasks, which can be digital and/or non-digital and can promote deep meaningful learning. Therefore, the design of game-based learning helps learners to engage in the meaning-making process and ensure better participation. As the boundaries of classroom learning become blurred through blended or hybrid learning approaches, game-based learning enhances digital literacies for digital natives to prepare them for building a knowledge economy. By exploring existing literature, this chapter highlights how technology can support teachers and learners to go beyond their existing pedagogical boundaries by focusing on ways games may serve as digital sources of learning. It also explores the role game-based pedagogies and digital learning design frameworks play in enhancing learner engagement, collaboration, and cultural understanding.

Published: December 2021

Game-based learning is widely followed at the school level in India, but the higher education system has been longer in adopting it. The pandemic situation has transformed teaching and learning processes from the traditional to the technical method, which requires a more versatile approach. Because of the rapid change from the offline mode to the online mode in higher education, there is little evidence available on the inefficiency of implementing the traditional system of teacher-centered education on online platforms. There comes a lot of the significance in of adapting technology-based games in order to engage and motivate students throughout their course of study. The aim of this chapter is to provide an overview of the effectiveness of game-based learning strategies over traditional learning methods. Moreover, the results of a cross-sectional study conducted by the authors in South Indian universities at the higher education level is included.

Key considerations in mass masking during the COVID-19 outbreak: a scoping review
Authors: Seneviratne Ruwanika , Marasinghe Anoma , Yasaratne Niludi , Weerasinghe Manuj
Published: December 2021

BackgroundMany countries are gradually returning to normalcy after varying periods under lockdown following the coronavirus disease (COVID-19) pandemic. In the transitional period from lockdown to resumption of work and thereafter, hygiene-oriented measuresincluding face mask usagewill need to be continued by the public. Though mass masking has been suggested to block transmission of COVID-19 infection, there are key considerations that need attention when this strategy is adopted by the general public on a mass scale for a considerable period of time. This study aims to review research evidence pertaining to key considerations related to mass maskingby the general public during the COVID-19 outbreak.Methods We carried out a scoping review and identified relevant literature until 30thof September 2020 searching databases and other sources comprehensively. This scoping review was registered under Open Science Framework and is available on osf.io/vj9a6.ResultsA total of 42 articles were included in this scoping review. Consensus statements and guidelines were common. Evidence specific to COVID-19 is limited.ConclusionThere is no conclusive evidence of benefits from introduction of mass masking as a single interventionin preventing transmission of viral-borne respiratory infections. However, beneficial effects are noted when mass masking is always combined with other non-pharmacological measures and when used by symptomatic patients as a means of source control of the disease. Evidence of mass masking on preventing transmission of viruses from asymptomatic persons is not available. In addition, cloth masks and homemade masks have varying degrees of effectiveness; however, the protection conferred is inferior compared to that of respirators and surgical masks.

Authors: Gunawardane D. A. , Dharmaratne S. D. , Rowel D. S.
Published: December 2021

Background: Even though forty to seventy percent of neonatal mortality are recorded among term neonates, information on neonatal outcomes of term neonates is scarce. The high volume of term neonatal admissions to neonatal care units(NCU)signifies the importance of studying the maternal risk factors for such neonatal outcomes. Objectives:The present study aims to identify the maternal risk factors for' “adverse neonatal outcome'' (ANO) following term deliveries at Teaching Hospital Kandy. Methods:An unmatched case-control study was nested within a descriptive follow-up study. A sample of 1105 neonates, delivered at termat Teaching Hospital Kandy, was followed up until their initial discharge point. Results:Multivariate analysis, found that caesarean section with labour increases the risk of  ANOamong term neonates by 3.37 ( CI- 2.13-5.33) times compared to normal vaginal delivery. Further, 37 completed weeks of Period of Amenorrhea (POA) (OR-2.91,1.57-5.42), Pregnancy Induced Hypertension (PIH) (OR-2.46,  CI- 1.27-4.75), Gestational Diabetes Mellitus (GDM) (OR-2.33,  CI- 1.0-5.15), primiparity (OR-1.53,  CI- 1.02-2.30) and maternal occupation as professionals (OR-3.45,  CI- 1.46-8.13) was identified  as  independent risk factors of ANO among term neonates. Conclusions: Caesarean section with labour, 37 completed weeks of POA, PIH, GDM, primiparity and maternal occupation as professional are independent risk factors for ANOin term neonates.

Published: December 2021

The use of topical olive oil (OO) for skin health is common among Saudis and worldwide. Therefore, this cross-sectional study is aimed at assessing the use of topical OO for skin health among Saudis in Riyadh, Saudi Arabia. The questionnaire was administered to Saudis at four different malls in Riyadh, Saudi Arabia. A total of 401 participants were enrolled in the study. The results showed that the average knowledge score of the participants was 3.4±0.3 (out of 5) and 87% had fair knowledge. The top source of knowledge among the participants was friends/relatives. In the attitude section, the average score was 4.1±0.5 (out of 5). Females had a higher attitude score 4.2±0.5 as compared to males 4±0.5 (P=0.03). The most common reason for using topical OO among the participants was skin moisturizing (73%). Female gender was the only significant factor associated with the use of topical OO (P < 0.001). The use of topical OO for skin health is highly prevalent in Riyadh, Saudi Arabia. Therefore, more awareness of the benefits and adverse effects of topical OO use is required especially from health educational organizations. The preliminary results of this study suggest further research with a larger sample in an academic setting across the nation.
Acne mimickers
Authors: Kandhari Rajat
Published: December 2021

Acne is now considered a chronic disease and may occur at any age group contrary to previous beliefs. The presentation of acne is polymorphic and can manifest as comedones, papules, pustules, nodules, cysts, sinuses, and varying kinds of scars. It may occur in varied areas of the body. Although the diagnosis of acne is rarely difficult for the dermatologist, the occurrence of acne in different age groups, the pleomorphic lesions, the varying distribution, and its association with various systemic disorders or syndromes may cause difficulties in diagnosis even for an astute clinician. Here, we review various diagnostic possibilities of acne and their differentiating characteristics.
Impact of cell culture methods on the outcomes of the in vitro inflammatory response in nasal polyps
Authors: Fernández-Bertolín L. , Mullol J. , Alobid I. , Roca-Ferrer J. , Picado C. , Pujols L.
Published: December 2021

Background: In vitro culture of nasal polyp cells is frequently used in the investigation of inflammatory mechanisms and effect of treatments in nasal polyposis. Research outcomes may, however, be influenced by the culture methodology used. Methods: Nasal polyp and nasal mucosa in vitro fibroblast cultures were pre-treated with foetal bovine serum (FBS)-free culture medium or medium supplemented with either FBS or charcoal-stripped (cs) FBS. Cells were then stimulated with FBS or csFBS, with or without different doses of dexamethasone for 4 and 24h. IL-6, IL-8, GM-CSF and VEGF release and cell viability were measured. Results: The highest cytokine levels were found in growth-arrested cells stimulated with 10% FBS. csFBS poorly stimulated cytokine release. Nasal polyp released larger IL-8 amounts than nasal mucosa fibroblasts. Dexamethasone decreased cytokine production dose- and time-dependently in both nasal mucosa and nasal polyp fibroblasts. The IC25 of IL-8 inhibition by dexamethasone was higher in nasal polyp than in nasal mucosa fibroblasts. Cell viability did not differ among treatments. Conclusions: Cytokine production by in vitro cultured nasal fibroblasts is affected by the culture conditions used and is inhibited by dexamethasone in both fibroblast types. Our results highlight the importance of culture methodology on nasal polyp research outcomes.

Objectives: To describe the use of antibiotics in an ED and level of prescribing adherence to national guidelines.

Methods: Retrospective observational study of antibiotic practice in ED. All patients who presented to ED during the study period and were prescribed an anti-microbial agent were included. Data on demographics, working diagnosis, anti-microbialprescribed, dose, route and prescriber level were used to provide descriptive statistics of these parameters.

Results: We identified 195 (13.4%) patients who received anti-microbial therapy among 1454 charts reviewed. The mean age was 34.8 with male predominance. The most common indication identified was abscess in 37 (30.8%) patients and in general surgical conditions had the highest rate of antimicrobials prescribed at 54.3%. In addition, co-amoxiclav was the most commonly prescribed anti-microbial (72.15%). We found that combination therapy was not common practice in ED, with majority of the patients having received single anti-microbial therapy (87.18%). The appropriateness of antimicrobial prescriptions was (46.2%) and not statistically significant (P = 0.654).

Conclusion: The most commonly prescribed anti-microbial was co amoxiclav and the most common indication was abscess. It was found that antibiotic prescription appropriateness was acceptable when compared to studies conducted in developedcountries. However, further research within other hospital departments will add to the study to determine the adherence as an institution rather than the Emergency department alone, as antimicrobial resistance is a major global healthcare problemand impacts patient care throughout the care pathway.

Background: Streptococcus pneumoniae (S. pneumoniae) is the first leading cause of invasive diseases such as meningitis, bacteremia and pneumoniae in children. In this case we report an early neonatal respiratory distress revealing meningitis caused byS. pneumoniae Serotype 17F through vertical transmission, in the newborn of 3 hours of live.

Case description: A male late preterm newborn was born by vaginal delivery at a gestational age of 34 weeks. At 3 hours of life, he was admitted for early moderate neonatal respiratory distress in the Neonatal Medicine and Resuscitation Service.Cerebrospinal fluid culture yielded S. pneumoniae belonging to serotype 17F while the blood culture was negative. The same pneumococcal serotype was recovered from the high vaginal swab of the mother. Both isolates were found susceptible to all tested antibiotics except tetracycline and chloramphenicol to which the strain was resistant. Antibiotherapy management of the child included ceftriaxone at 150mg/kg/day for 21 days, in combination with gentamycin at 5 mg/kg/day for 5 days. ciprofloxacin was added at 40mg/kg/day in two doses for a period of three weeks as the baby presented a hydrocephalus.

Conclusion: This finding shows that clinical manifestations of neonatal pneumococcal meningitis may be atypical and/or misleading.

Keywords: Streptococcus pneumoniae; neonatal meningitis; respiratory distress.

Background: Persistent infection with high-risk (HR) papillomavirus (HPV) genotypes plays a central role in the pathogenesis of invasive cervical cancer.

Objectives: This study aimed to determine the prevalence and distribution of HR-HPV among women with or without cervical lesions at VIA/VILI in Togo.

Methods: Cervical samples were collected from 238 women with or without cervical lesions at VIA / VILI and[c3] DNA [c4]was extracted and analyzed by real-time multiplex PCR. Logistic regression analysis was used to determined risk factors associated with HPV infection. inPietro Annigoni Biomolecular Research Center (CERBA / LABIOGENE) in Burkina Faso.

Results: The age of the women ranged from 17 to 61 years old, and most were married (73.5%). The prevalence of HRHPV was 35.71% and this was higher in the age range 35-39 years. The six most common genotypes were HPV 31 (18.7%), HPV 52 (13.82%), HPV 68 (13.01%), HPV 66 (9.76%), HPV 58 (8.13%) and HPV 56 (8.13%). Genotypes HPV 18 (4.07%)and HPV 16 (0.81%) were less frequent.[c5] Married or living with a partner was associated with HPV infection ( OR=2,17, IC [1.20-3.91], p<0,009).

Conclusion: This study allowed characterizing for the first time in Togo, HR-HPV genotypes. This will help mappingHR-HPV genotypes circulating in West Africa.

Authors: Ilesanmi Olayinka , Afolabi Aanuoluwapo , Kwaghe Ayi
Published: December 2021

Background: The implementation of COVID-19 lockdown measures across the globe could affect adolescents’ health.

Objective: This review was conducted to assess the impact of the COVID-19 lockdown on the health of the adolescents.

Methodology: We conducted this study using the scope reviews methodological framework. We searched for articles on the effects of COVID-19 lockdown among adolescents on four databases; MedLine, PubMed, Directory of Open Access Journals and Google Scholar. Screening of articles was done for relevance to the study objective.

Results: The positive effects of the COVID-19 lockdown on adolescents included increased physical activity for adolescents 17 years and below, increased resource mobilization for healthy lifestyle, and psychosocial support programs for schools. The negative effects of the lockdown period were decreased physical activity with resulting disruptive sleep patterns; increased screen time, behavioral addictive disorder from excessive use of the internet, increased levels of domestic abuse,and worsening of existing mental health disorders. Overall, the COVID-19 lockdown period has had considerable adverseeffects on adolescents’ health.

Conclusion: To curb the negative effects of the COVID-19 lockdown, we recommend parental supervision of adolescents’ screen time. Adolescent health should be prioritized by policymakers to ensure that future lockdown does not adversely affect them.

On Defining the Participatory Museum: The Case of the Museum of the Second World War in Gdansk
Authors: Manikowska Ewa , Jakubowski Andrzej
Published: December 2021

This article seeks to contribute to the current debate on the new definition of the “museum” – a debate which led to turmoil at the 2019 ICOM General Assembly in Kyoto. With reference to the case study of the Museum of the Second World War in Gdansk (MSWW), it analyses the new and very successful genre of the narrative museum, a genre which arguably fulfils the core elements of the definition currently being discussed by ICOM. In this regard, it brings into focus the paramount importance of community involvement in creating and managing narrative museums – an aspect that has been virtually absent in the academic and media debates over the nature of the MSWW and its programme. By pointing out the fragility of the foundations for such participation, based solely on trust between communities, the museum, and state authorities, this article calls for and provides guidance for an academic and institutional redefinition of the narrative museum and the institution of a museum in general.
Is Scientific Creativity Possible in Early Childhood?
Authors: Yıldız Taşdemir Cansu
Published: December 2021

It can be stated that scientific creativity is a fairly new research topic for early childhood. Although creativity is one of the skills that are frequently discussed in early childhood research, studies dealing with scientific creativity, a type of creativity specifically related to science, are very limited regarding this period. In this review study, scientific creativity was conceptually examined and research conducted on scientific creativity with children attending primary and secondary school were included. Whether scientific creativity is possible in early childhood was examined according to a limited number of studies examining scientific creativity in this period. Additionally, based on previous studies, suggestions were given on how to support scientific creativity in early childhood.

conciencia documentaria de los sefardíes en los archivos personales: el caso de Judá Haim Perahiá
Authors: Gruss Susy
Published: December 2021

La empresa de coleccionar y archivar materiales entre los intelectuales sefardíes puede considerarse un fenómeno moderno en el campo de la cultura material. Este proceso tardío, que comenzó entre los sefardíes sólo a finales del siglo XIX, es uno de los resultados directos del impacto de la Ilustración judía, la Haskalá. El presente artículo se centrará en la descripción y el análisis del Archivo Perahiá, custodiado en la Biblioteca Ben-Zvi de Jerusalén. Este estudio de caso, que ofrece un corpus significativo para reflexionar sobre la autoconciencia documentaria de los sefardíes en el período moderno, podrá servir de modelo para estudiar otros archivos similares.
