Background and Purpose: It is believed that stroke occurring due to posterior circulation large vessel occlusion (PCLVO) and that occurring due to anterior circulation large vessel occlusion (ACLVO) differ in terms of their pathophysiology and the outcome of their acute management in relation to endovascular mechanical thrombectomy (MT). Limited sample size and few randomized controlled trials (RCTs) with respect to PCLVO make the safety and efficacy of MT, which has been confirmed in ACLVO, difficult to assess in the posterior circulation. We therefore conducted a meta-analysis to study to which extent MT in PCLVO differs from ACLVO.Materials and Methods: We searched the databases PubMed, Cochrane, and EMBASE for studies published between 2010 and January 2021, with information on risk factors, safety, and efficacy outcomes of MT in PCLVO vs. ACLVO and conducted a systematic review and meta-analysis; we compared baseline characteristics, reperfusion treatment profiles [including rates of intravenous thrombolysis (IVT) and onset-to-IVT and onset-to-groin puncture times], recanalization success [Thrombolysis In Cerebral Infarction scale (TICI) 2b/3], symptomatic intracranial hemorrhage (sICH), and favorable functional outcome [modified Rankin Score (mRS) 0–2] and mortality at 90 days.Results: Sixteen studies with MT PCLVO (1,172 patients) and ACLVO (7,726 patients) were obtained from the search. The pooled estimates showed higher baseline National Institutes of Health Stroke Scale (NIHSS) score (SMD 0.32, 95% CI 0.15–0.48) in the PCLVO group. PCLVO patients received less often IVT (OR 0.65, 95% CI 0.53–0.79). Onset-to-IVT time (SMD 0.86, 95% CI 0.45–1.26) and onset-to-groin puncture time (SMD 0.59, 95% CI 0.33–0.85) were longer in the PCLVO group. The likelihood of obtaining successful recanalization and favorable functional outcome at 90 days was comparable between the two groups. PCLVO was, however, associated with less sICH (OR 0.56, 95% CI 0.37–0.85) but higher mortality (OR 1.92, 95% CI 1.46–2.53).Conclusions: This meta-analysis indicates that MT in PCLVO may be comparably efficient in obtaining successful recanalization and 90 day favorable functional outcome just as in ACLVO. Less sICH in MT-treated PCLVO patients might be the result of the lower IVT rate in this group. Higher baseline NIHSS and longer onset-to-IVT and onset-to-groin puncture times may have contributed to a higher 90 day mortality in PCLVO patients.

Objective: To investigate the impact of albumin levels on the aspirin efficacy, since aspirin inhibits platelet aggregation (PA) by cyclooxygenase one irreversible acetylation that is less effective in patients with type 2 diabetes mellitus (T2DM).Patients and Methods: A total of 612 aspirin (100 mg/day)-treated T2DM patients were followed-up for 54.4 ± 7.3 months. The primary endpoint, a composite of cardiovascular events (CVEs) including CV death, myocardial infarction, ischemic stroke and coronary revascularization, was analysed according to baseline values of serum albumin (≥ or &lt; 3.5 g/dL). Serum thromboxane (Tx)B2 was also measured.Results: 250 (40.8%) patients had serum albumin &lt; 3.5 g/dL; these patients were overweight and had higher values of fibrinogen (p = 0.009), high sensitivity C-reactive protein (p = 0.001) and fasting plasma glucose (p &lt; 0.0001) compared to those with albumin ≥ 3.5 g/dL. During follow-up, 86 CVEs were recorded, 49 and 37 in patients with serum albumin &lt; or ≥3.5 g/dL, respectively (p = 0.001). At multivariable Cox regression analysis, serum albumin &lt; 3.5 g/dL (hazard ratio [HR] 1.887, 95% confidence interval [CI] 1.136–3.135, p = 0.014), age (HR 1.552 for every 10 years, 95%CI 1.157–2.081, p = 0.003), fasting plasma glucose (HR 1.063, 95%CI 1.022–1.105, p = 0.002) and beta-blocker use (HR 0.440, 95%CI 0.270–0.717, p = 0.001) were associated to CVEs. Serum TxB2 levels (n = 377) were 0.32 ± 0.12 and 0.24 ± 0.12 ng/ml in patients with albumin &lt; or ≥ 3.5 g/dL, respectively (p &lt; 0.001).Conclusion: In T2DM patients, the efficacy of aspirin varies according to albumin levels. Hypoalbuminemia associated with impaired TxB2 inhibition and an increased risk of long-term CVEs.

Objective: Depressive symptoms (depression hereafter) is common in older adults, and closely associated with environmental factors. This study compared the prevalence of depression in older adults living in high-altitude and low-altitude regions, and their association with quality of life (QOL).Method: A total of 632 older nursing home residents were included, with 425 participants living in low-altitude and 207 participants living in high-altitude regions. Depression and QOL were assessed using standardized instruments.Results: The prevalence of depression was 26.9% (95% CI: 23.43–30.37%) in the whole sample of older nursing home residents, with 11.1% (95% CI: 8.01–14.05%) in those living in low-altitude and 59.4% (95% CI: 52.68–66.17%) in those living in high-altitude regions. Multiple logistic regression analysis revealed that living in low-altitude region (P &lt; 0.001, OR = 0.07, 95% CI: 0.04–0.12) was associated with lower risk of depression, while perception of poor health status (P &lt; 0.001, OR = 3.86, 95% CI: 1.98–7.54) and having insomnia (P &lt; 0.001, OR = 4.76, 95% CI: 2.99–7.56) were associated with higher risk of depression. QOL was significantly lower in physical (F(1,632) = 35.421, P &lt; 0.001), psychological (F(1,632) = 20.777, P &lt; 0.001), social (F(1,632) = 8.169, P &lt; 0.001) and environmental domains (F(1,632) = 11.861, P &lt; 0.001) in those with depression.Conclusion: Depression was common in older nursing home residents especially those living in the high-altitude region. Considering the negative impact of depression on QOL and functional outcomes, routine screening and timely treatment of depression should be implemented in this population.

Published: June 2021

During the COVID-19 pandemic, the higher susceptibility of post-stroke patients to infection calls for extra safety precautions. Despite the imposed restrictions, early neurorehabilitation cannot be postponed due to its paramount importance for improving motor and functional recovery chances. Utilizing accessible state-of-the-art technologies, home-based rehabilitation devices are proposed as a sustainable solution in the current crisis. In this paper, a comprehensive review on developed home-based rehabilitation technologies of the last 10 years (2011–2020), categorizing them into upper and lower limb devices and considering both commercialized and state-of-the-art realms. Mechatronic, control, and software aspects of the system are discussed to provide a classified roadmap for home-based systems development. Subsequently, a conceptual framework on the development of smart and intelligent community-based home rehabilitation systems based on novel mechatronic technologies is proposed. In this framework, each rehabilitation device acts as an agent in the network, using the internet of things (IoT) technologies, which facilitates learning from the recorded data of the other agents, as well as the tele-supervision of the treatment by an expert. The presented design paradigm based on the above-mentioned leading technologies could lead to the development of promising home rehabilitation systems, which encourage stroke survivors to engage in under-supervised or unsupervised therapeutic activities.

Actualmente nos encontramos en una carrera logística respecto a la enfermedad COVID-19. Uno de los signos característicos en pacientes severos son las alteraciones en el recuento de linfocitos. El objetivo de este trabajo es valorar y relacionar la evidencia científica disponible sobre la relación existente entre la linfopenia y los casos severos de la enfermedad COVID-19. Para poder llevar a cabo la investigación, se ha realizado una revisión sistemática de artículos científicos consultando la base de datos PubMed, en los idiomas español e inglés.
Hay estudios que sugieren vías por las cuales el virus SARS-CoV2 induce una linfopenia por lisis directa de los linfocitos, una disminución indirecta, mediante la afectación de órganos linfáticos o inducción de vías apoptóticas. Mientras que otras publicaciones describen un fenotipo exhausto de la población linfoide, presentando habilidad reducida en cuadros severos de COVID-19. Finalmente, se describe también como causa potencial de la disminución de linfocitos T circulantes al secuestro o redistribución de dichos linfocitos T hacia sitios de inflamación.
Los estudios sobre COVID-19 han permitido determinar la linfopenia como un signo frecuente en cuadros severos de la enfermedad. Convirtiendo así esta alteración en el hemograma en un factor pronóstico de la enfermedad. Es evidente la necesidad de investigación adicional respecto a los muchos factores causantes de la linfopenia, ya que por el momento no es posible aclarar cuales subpoblaciones de pacientes desarrollarán cuadros severos con los hallazgos y la bibliografía disponible a la fecha.

Исламские банки доказали свою эффективность и действенность как в методах финансового управления, так и в мобилизации финансовых ресурсов для содействия развитию в различных экономических секторах не только в исламских странах, но и в европейских, в соответствии с исламскими шариатскими нормами. Цель статьи заключается в изучении показателей и исламских методов, принятых для улучшения распределения финансовых ресурсов, и его конкретных путей повышения доходов. Кроме того, исламские финансовые активы были задействованы на огромных финансовых рынках благодаря высокому качеству финансовых услуг, предоставляемых инвесторам. Собственно, исламский банкинг существует более чем в 67 странах и к концу 2021 года может охватить около 75 стран мира. Результаты показывают, что успешность развития индустрии исламских финансовых активов лежит в фундаментальных аспектах построения архитектуры исламского банкинга, как наиболее распространенного сегмента исламских финансов.
Islamic banks have proved their effectiveness and efficiency in both financial management and the mobilization of financial resources to promote development in various economic sectors, not only in Islamic countries, but also in European ones, in accordance with Islamic sharia norms. The purpose of the article is to examine the indicators and Islamic methods adopted to improve the allocation of financial resources and its specific ways to increase income. In addition, Islamic financial assets were used in huge financial markets due to the high quality of financial services provided to investors. Actually, Islamic banking exists in more than 67 countries and by the end of 2021 it can cover about 75 countries of the world. The results show that the success of the Islamic financial asset industry lies in the fundamental aspects of building the architecture of Islamic banking, as the most common segment of Islamic finance.

Natural Night Sky Brightness during Solar Minimum

Published: June 2021

Abstract
In 2018, Solar Cycle 24 entered into a solar minimum phase. During this period, 11 million zenithal night sky brightness (NSB) data were collected at different dark sites around the planet, including astronomical observatories and natural protected areas, with identical broadband Telescope Encoder and Sky Sensor photometers (based on the Unihedron Sky Quality Meter TLS237 sensor). A detailed observational review of the multiple effects that contribute to the NSB measurement has been conducted with optimal filters designed to avoid brightening effects by the Sun, the Moon, clouds, and other astronomical sources (the Galaxy and zodiacal light). The natural NSB has been calculated from the percentiles for 44 different photometers by applying these new filters. The pristine night sky was measured to change with an amplitude of 0.1 mag/arcsec2 in all the photometers, which is suggested to be due to NSB variations on scales of up to months and to be compatible with semiannual oscillations. We report the systematic observation of short-time variations in NSB on the vast majority of the nights and find these to be related to airglow events forming above the mesosphere.
Séquences de « perlustration » dans les échographies prénatales : dire et voir le sexe
Authors: Licoppe Christian , Greco Luca , Rollet Nicolas 
Published: June 2021

Dans cet article, nous étudions des enregistrements vidéo d’échographies prénatales dans la perspective de l’ethnométhodologie et l’analyse de conversation (EM/CA). Nous nous focalisons sur les séquences de perlustration interactionnelle qui portent sur la reconnaissance du sexe du fœtus. Nous montrons comment ces séquences peuvent émerger selon deux trajectoires différentes, l’une orientée sur une découverte unilatérale du sexe par l’expert, l’autre, plus collaborative, orientée vers un « voir ensemble ». Ces deux trajectoires interactionnelles manifestent des formes d’articulation différentes entre modalités de la connaissance, cadres de participation et formes de couplage des énoncés avec leur environnement. Nous montrons comment leur analyse et leur compréhension nécessite de mobiliser simultanément les deux aspects principaux du travail de Goodwin, d’un côté la multimodalité et le concept d’« énoncé couplé à l’environnement », et de l’autre, la notion de « vision professionnelle ».

Les gestes de pointage dans un environnement changeant et éphémère : les leçons de conduite
Authors: De Stefani Elwys , Deppermann Arnulf 
Published: June 2021

Parmi les nombreuses contributions de Charles Goodwin à l’étude des interactions sociales, ses travaux sur les gestes de pointage (1986, 2003, 2007) et la vision professionnelle (1994) constituent un apport majeur. Forts de l’enseignement goodwinien, nous examinons le recours aux gestes de pointage lors des instructions de navigation observables dans des leçons de conduite. Nous décrivons quatre exécutions indexicales différentes des gestes de pointage employés pour indiquer un parcours à suivre : les gestes trajectoire, les gestes géométriques, schématiques et contrastifs. Les gestes trajectoire tracent une ligne dans l’espace, révélant ainsi une composante déictique et une composante iconique. Les gestes géométriques instaurent une relation vectorielle avec la configuration routière visible, alors que les gestes schématiques reposent sur une représentation sémiotique stylisée de l’environnement. Ni complètement géométriques, ni schématiques, les gestes contrastifs se basent sur une représentation oppositionnelle de l’espace ambiant. La mobilité des interactants, leur asymétrie épistémique, l’activité didactique, et la séquentialité de l’interaction contribuent à donner leur sens à ces gestes de pointage.
Continuum et maintien du lien social professionnel en situation de conflit verbal écrit : être poli ou impoli, mais y mettre les formes
Authors: Fracchiolla Béatrice , Romain Christina 
Published: June 2021

Le contexte même des échanges électroniques (interaction verbale asynchrone) les rend plus propices à la tension verbale : certains éléments (linguistiques et discursifs) y sont exacerbés en raison de l’absence d’autres éléments (prosodiques et mimogestuels) généralement présents dans les communications synchrones. En quoi et comment les échanges de courriels à plusieurs personnes en contexte institutionnel favorisent alors la cristallisation de la tension verbale et quels peuvent être leurs impacts sur le devenir de l’interaction verbale asynchrone ? Constitué de courriels de type CC échangés entre universitaires, notre corpus est étudié sous l’angle de l’analyse linguistique de la violence verbale, en tant que montée en tension contextualisée se déclinant à travers différentes étapes dont : des actes de langage dépréciatifs, des marqueurs discursifs de rupture, des déclencheurs de conflits, et l’analyse du fonctionnement de l’agression verbale, de son impact et de sa gestion interactionnelle globale.
Révolte et ivresse
Authors: Lamarche-Vadel Gaëtane 
Published: June 2021

Les Iraniens et Iraniennes ont développé une intelligence pratique du contournement des interdits. Une séparation ancienne du privé et du public ( andaruni/biruni ) s’est transformée en un jeu subtil avec les valeurs, les modes de vie, les arts permis/prohibés. Illicites et présents partout mais à l’écart, la musique, les chants, les voix sont à la fois particulièrement prisés et contrôlés. Saisissant ce sujet, des cinéastes et des musiciens traitent de la censure et produisent en même temps ce qui est illicite : la musique à travers des concerts, auditions, répétitions. Des chansons réfèrent à des poèmes soufis prônant l’ivresse et la révolte.
La République islamique d’Iran
Authors: Therme Clément , Lamarche-Vadel Gaëtane 
Published: June 2021

L’auteur analyse la politique intérieure et extérieure de la République islamique d’Iran en phase avec une situation économique et sociale très dégradée et un contexte géopolitique fortement bousculé ces derniers temps. L’élection du nouveau président Joe Biden aux États-Unis, la surenchère de l’Iran sur le programme d’enrichissement de l’uranium, les élections iraniennes prochaines avec une tendance néoconservatrice annoncée, le rapprochement israélo-gulfien obligent à rebattre les cartes. Comment ces phénomènes vont-ils se croiser et dans quel sens ? Apaisement ou au contraire durcissement des positions ? Sur quels alliés l’Iran peut-il compter ? Dans quelle mesure la population iranienne exerce-t-elle une influence sur les orientations gouvernementales du pays à l’extérieur de ses frontières ?
