Les remontrances du parlement de Paris : instrument de conseil et arme de contestation du pouvoir monarchique au xviiie siècle
Authors: Feutry David
Published: April 2024

Outil privilégié de régulation de la loi royale par les parlements, les remontrances changent de nature au cours du xviiie siècle. Autrefois utilisées pour former des réserves uniquement sur la forme des lois, elles deviennent après 1715, notamment pour le Parlement de Paris, un moyen de contester la politique royale. Progressivement, le Parlement de Paris forme une doctrine de plus en plus cohérente visant moins à se substituer à l’autorité royale qu’à lui rappeler l’essence même du pouvoir auquel le Parlement souhaite être associé. Pourtant, en contrôlant le droit (grâce aux registres) et l’histoire (par le travail acharné d’Adrien Le Paige), les parlementaires avaient progressivement sapé les bases de l’édifice monarchique.
Pétitions parlementaires et littérature politique en Angleterre, xiiie-xive siècles
Authors: Lachaud Frédérique
Published: April 2024

À partir de la fin du xiie
siècle, l’essor des enquêtes et le développement des plaintes en
justice marquèrent les rapports entre le roi d’Angleterre et ses
sujets. L’institutionnalisation des parlements conduisit aussi à la
formalisation écrite des plaintes, qui canalisèrent les doléances des
sujets du roi, sans pour autant mettre fin aux pétitions
extra-parlementaires. L’analyse de ce processus permet de rendre
compte de l’importance nouvelle du thème de la doléance dans la
littérature à partir de la fin du xiiie
siècle. Miroirs aux princes et pamphlets politiques se firent aussi
l’écho des plaintes en Parlement. Il s’agit de considérer dans le même
temps ces différents aspects, tout comme l’iconographie de deux
manuscrits des premières décennies du xive
siècle, qui représentent pour la première fois la procédure de plainte
en Parlement.
Entre économie du salut et construction de l’État moderne : les querimoniae collectées par Louis IX lors des enquêtes de réparation (1247-1270)
Authors: Dejoux Marie
Published: April 2024

Inquesta, inquisitio, querela, et surtout querimonia – la doléance – sont les termes
qui désignent les vastes enquêtes ordonnées par Louis IX avant la
croisade en 1247-1248 et jusqu’à sa mort en 1270. De ces enquêtes
destinées à réparer financièrement les exactions commises par le roi,
ses prédécesseurs et par ses officiers, nous gardons avant tout la
trace de l’audition des requérants, soit des milliers de doléances
politiques. Conformation à un impératif de restitution des male ablata alors prôné par
l’Église et par les ordres mendiants, ces enquêtes de réparation sont
à distinguer clairement des enquêtes de réformation des derniers
Capétiens. Cette contribution s’attache donc à en restituer le
contexte spécifique. Particulièrement précoce, cette collecte de
doléances constitue sans doute l’une des manifestations les plus
spectaculaires d’un art de gouverner singulier, mêlant tout à la fois
la contrainte et le consentement, le souci d’imposer sa souveraineté
et le scrupule religieux : une « redemptive governance ».
Pétitions et plaintes collectives en Flandre médiévale : les acteurs et les institutions
Authors: Braekevelt Jonas , Dumolyn Jan
Published: April 2024

La présente contribution se propose de montrer
comment les rares documents dont on dispose pour la Flandre médiévale,
et que l’on peut qualifier de « cahiers de doléances », bien que
chronologiquement et géographiquement fragmentés, révèlent des
conflits sociopolitiques. Ces documents évoquent en effet les acteurs
et les institutions concernés, leurs interactions et leurs rapports de
forces en des lieux et temps précis, ainsi que les discours
idéologiques produits dans le cadre d’une pratique politique
« populaire ». Sur le plan diplomatique, la plainte se présente tout
d’abord comme un document juridique et politique, doté de
caractéristiques plus ou moins formelles et produit dans des
circonstances tantôt « institutionnalisées » tantôt plus
« spontanées ». Mais si l’on considère les choses sous l’angle
performatif, elle apparaît aussi comme le résultat d’un processus
discursif, le fruit d’une « parole » qui s’inscrit dans une logique de
« politique populaire »
La plainte dans l’économie politique de quelques états provinciaux en France et en Franche-Comté (xviie-xviiie siècles)
Authors: Loiseau Jérôme
Published: April 2024

En France, sous l’Ancien Régime, les doléances
se trouvent au cœur « d’une civilisation de l’État », renouvelée par
l’affirmation du droit divin des rois. Elles leur offrent un théâtre
où représenter leur nature divine. Interactions politiques majeures
entre les provinces d’États et la monarchie, elles habilitent ceux qui
y participent et sont l’occasion de déployer une politique de la
douceur dont les vecteurs visent à honorer les interlocuteurs
officiels et à susciter leur bienveillance dans le cadre d’une
politesse publique et d’une éthique qui exigent du service rendu une
récompense en retour. Le roi de France peut ainsi entendre et
éventuellement écouter, pour peu que les prières de ses sujets
respectent la formalité inhérente à la majesté monarchique. Dès lors,
Bourguignons, Bretons et Languedociens peuvent espérer attirer
l’attention d’un roi forcément contraint par « l’état de ses affaires
».
Lille au XVIIIe siècle
Authors: Dormard Serge
Published: April 2024

L’histoire financière des villes de l’Ancien Régime reste mal connue. Cet ouvrage comble en partie cette lacune à partir d’une approche combinant l’examen approfondi des comptes de la ville de Lille sur un siècle et divers instruments et concepts de l’analyse économique. Parmi les dépenses urbaines, une attention particulière a été portée à l’évolution des lourds impôts royaux à la charge de la ville. Les recettes abondantes procurées par les multiples octrois concédés à la cité nordiste par les souverains successifs font l’objet d’une étude minutieuse. L’analyse économique a permis de répondre à des questions aussi essentielles que celle de savoir qui supporte le poids de l’impôt. Elle a aussi permis d’évaluer les impacts de certaines règlementations adoptées par les édiles lillois. Un diagnostic précis de la santé financière de la ville de Lille à la veille de la Révolution a été établi grâce à l’utilisation d’indicateurs standards de l’analyse financière des collectivités locales.
Utiliser la vidéo pour le développement de dispositions à agir dans des pratiques professionnelles à forte dimension sensorimotrice. Le cas de la formation au travail à la main au Cadre noir de Saumur

Published: April 2024

Cet article présente une contribution méthodologique sur l’exploration des expériences sensorimotrices dans l’activité experte d’écuyers du Cadre noir. La réflexion est développée en référence au programme de recherche du Cours d’action. Elle expose différentes voies d’enrichissement des situations d’autoconfrontation aux traces vidéo de l’activité. Elle met en évidence la fécondité de l’articulation de différents modes de construction des données en accord avec une approche énactive de la pratique experte, afin d’accéder aux dimensions incarnées de celles-ci. Elle ouvre également des perspectives pour le développement de dispositions à percevoir et à agir dans le cadre d’interactions complexes humain-animal.
Une relecture du cas de Gaël
Authors: Prot Frédérique Marie , Go Henri Louis
Published: April 2024

Cette contribution propose une relecture de l’un des textes fondateurs de la didactique : Le cas de Gaël. Il s’agit d’en rappeler la problématique, en s’appuyant à la fois sur le texte de Brousseau et sur le commentaire qu’en donne Gérard Sensevy dans Le sens du savoir (2011). Nous souhaitons montrer que l’ingéniosité didactique de Brousseau, pour débloquer le rapport de Gaël aux mathématiques, comporte une dimension qui a été sous-estimée, et que pourrait intégrer l’anthropologie didactique et plus spécifiquement la Théorie de l’Action Conjointe en Didactique : les « phénomènes transférentiels ». Entre Brousseau et Gaël se joue quelque chose qui est constitutif de la relation didactique, et qu’une attention clinique peut souligner.
Qui fait quoi autour du document en Histoire ? Trois études de cas sur le 11 septembre 2001 en classe de première
Authors: Morand Brigitte , Serres Guillaume
Published: April 2024

Le but de cet article est d’analyser l’utilisation de deux documents-sources dans trois classes d’histoire de première. L’analyse porte sur : a) les buts assignés aux séances, b) les tâches effectivement menées et c) la partition de ces tâches selon qu’elles étaient réalisées par les enseignant·es ou sollicitées auprès des élèves. Ces trois études de cas témoignent d’une évolution des pratiques ordinaires. Pourtant, si le document n’est plus pour ces trois enseignant·es expérimenté·es une illustration de la parole magistrale, des résistances, des hésitations et des compromis sont repérés. Nous mettons en évidence l’importance des tâches de conceptualisation, pour lesquelles les élèves sont largement sollicité·es, même si c’est dans le cadre d’un questionnement très guidé et à l’aide de questions fermées. Pour ces trois cas, le document n’est donc plus une simple illustration de la parole magistrale, même si les déroulements révèlent des hésitations et des compromis difficiles. Identifier les ambiguïtés qui sous-tendent ces hésitations, nous conduit à des pistes susceptibles d’aider les enseignants et enseignantes à les résoudre.
Infusing epistemic perspectives on scientific practices in science teacher education
Authors: Erduran Sibel , Saribas Deniz , Kaya Ebru
Published: April 2024

The paper provides a case for the inclusion of epistemic perspectives on scientific practices in science teacher education. Scientific practices are defined as being part of nature of science and are drawn from the account of the Family Resemblance Approach (FRA) developed by Erduran & Dagher (2014a). The depiction of scientific practices relies on a theoretical model called the Benzene Ring Heuristic (BRH) which consolidates the epistemic, cognitive and social aspects of scientific practices into a holistic and visual representation. BRH describes scientific practices in terms of concepts such as data, models, explanations, predictions, argumentation and social certification. We describe a funded project that integrated BRH into a pre-service science teacher education program and investigated the impact of the intervention on the pre-service science teachers. Qualitative analysis of pre-service science teachers’ perceptions of scientific practices are described and contrasted before and after the training intervention using BRH. The results indicate that in some cases there was improvement in pre-service science teachers’ depiction of scientific practices as being holistic. The study provides empirical evidence on the incorporation of an epistemic perspective on scientific practices in science teacher education.
« Sans même qu’ils s’en soient rendu compte »
Authors: Brackett David
Published: April 2024

Cet article propose une introduction à la théorie des genres musicaux telle que développée par David Brackett dans son livre Categorizing Sound (2016). Les sujets abordés dans cet article sont les suivants : l’opposition entre les modes « historicistes » et « présentistes » d’analyse des genres musicaux ; les processus de définition des genres musicaux par rapport à d’autres genres musicaux ; le lien entre les contextes au sein desquels les genres musicaux apparaissent et la façon dont ils sont compris ; les différents niveaux de genres, incluant les méta-genres et les sous-genres musicaux ; les processus d’itérabilité et de citationalité (ou de répétition et de différence) à travers lesquels des textes individuels participent d’un genre musical ; la naissance et la transformation des genres musicaux en réponse à la créativité collective et au dialogue entre musicien·nes, publics et intermédiaires (journalistes, personnel de l’industrie de la musique, etc.) ; et les catégories démographiques qui sont souvent évoquées dans la relation entre des genres musicaux et leurs publics particuliers. L’article conclut en abordant les débats récents sur la « fin imminente des genres musicaux ».
Taxonomies du métal
Authors: Smialek Eric
Published: April 2024

Cet article analyse cinq taxonomies de genre musical du métal de 2001 à 2010. J’y examine la manière dont leurs logiques et designs reflètent des croyances implicites sur les caractéristiques des genres musicaux et leurs relations. Des monographies universitaires jusqu’aux cartographies numériques, ces taxonomies s’appuient sur une conception linéaire de l’influence qui privilégie la lisibilité et la stabilité au détriment de relations plus complexes. Cet article soutient que ces visualisations des genres musicaux informent et reflètent des conceptions répandues – et souvent fausses – parmi les publics et les producteurs de musique métal. En attirant l’attention sur les postulats discrets qui se cachent derrière les taxonomies du métal, cet article entend aider les chercheur·ses à mieux comprendre les débats des fans sur les genres musicaux.
Le rock progressif (1969-1976) et la scène indie montréalaise (1997-2021) : influence stylistique et filiation artistique
Authors: Coulombe Bruno
Published: April 2024

Cet article explore le lien historique entre la scène indie montréalaise des années 2000 et le rock progressif, un genre qui a été très populaire au Québec dans les années 1970. M’inspirant des travaux de Brackett (2016), j’utilise une approche « généalogique » pour étudier l’influence du rock progressif chez les groupes indie montréalais. Un tel lien semble inconcevable de prime abord, l’indie préconisant la simplicité sur le plan de la production et du style (Fonarow, 2006), tandis que le rock progressif est centré sur la virtuosité et la théâtralité (Macan, 1997). Mon analyse révèle toutefois des contradictions dans la manière dont les genres opèrent. Dans la première partie, je retrace l’histoire du rock progressif de la période 1969-1976 dans le but d’expliciter son attrait auprès du public québécois, dans le contexte de la contre-culture. J’explore ensuite la notion de « scène » (Straw, 1991) pour en faire ressortir l’aspect intergénérationnel et établir des liens entre des époques distinctes (Bennett et Rogers, 2016). Enfin, j’explore diverses manifestations de l’influence du rock progressif sur les groupes indie de la période 1997-2021, comme l’illustrent la musique à grand déploiement de Godspeed You! Black Emperor, l’instrumentation élaborée d’Arcade Fire, les structures formelles non-conventionnelles de Malajube ou le post-psychédélisme des Besnard Lakes. En adéquation avec le modèle théorique de Brackett, je montre que ces groupes invoquent certaines conventions du rock progressif comme un ensemble de traits identifiables sans pour autant renier leur appartenance à leur genre d’origine.
June 1982, When Disco Became Dance
Authors: Haddon Mimi
Published: April 2024

Cet article analyse la transformation du disco en « musique dance », au sein des musiques populaires nord-américaines au début des années 1980. Je reviens tout d’abord sur un supplément du magazine Billboard, paru le 19 juin 1982, et consacré à une nouvelle catégorie connue sous le nom de « dance music ». À l’aide d’idées développées par David Brackett en 2016, dans son ouvrage Categorizing Sound, j’analyse cette transition générique de deux manières différentes. Dans un premier temps, je m’intéresse à la transition entre le disco et la dance selon l’idée de « niveau » de genres musicaux, et du concept concomitant d’« échec de la coordination » d’usage des étiquettes génériques au travers différents supports médiatiques, comme les palmarès de Billboard, la radio, les pistes de danse et les magasins de disques. Dans un second temps, je m’appuie sur l’idée de « regroupements provisoires » afin de souligner que les musiques populaires peuvent participer de plusieurs genres musicaux à la fois, et que différents critères génériques peuvent produire différents regroupements, parfois étonnants. Je suggère que ces regroupements émergents peuvent servir l’historiographie de la dance-music. Plus spécifiquement, je me demande si les sociabilités pré-rock et les groupes féminins sont ressuscités par les esthétiques ludiques des musiques disco-dance. Pour finir, peut-être la nouvelle dance music des années 1980 a-t-elle autant à voir avec les sociabilités de groupes féminins noirs et une pratique musicale incarnée, qu’elle n’a de rapport avec les nouveaux synthétiseurs, les bruits électroniques granuleux et un minimalisme épars.
Changing Preservice and Inservice Teachers' Commitment to Literacy as a Pathway to Social Justice
Authors: Lane Mae A. , Scott Chyllis E. , Benge Cindy , McCormick Montana K.
Published: April 2024

Discipline-specific teachers' commitment to teaching literacy within their content area to their students is often minimal. This chapter addresses how the authors sought to enhance teacher candidates and inservice teachers' commitment to content-area and disciplinary literacy with the use of virtual literacy circles in undergraduate and graduate level content-area literacy courses. The students read from selected texts with a focus on literacy as a social justice issue. Using a virtual platform, students responded virtually through two focused cycles. Following the project and virtual discussions, the students completed a post-assessment aimed at evaluating whether they had a change in their commitment to literacy and literacy instruction. The students' post-assessment responses were analyzed by the authors, using the lens to evaluate the students' posts within the virtual literacy circles to assess what led the students to change their commitment to literacy. Limitations, recommendations for future research, and implications are discussed.

Authors: Mammadov Arif , Ismayilov Nizami , Mammadov Elxan , Huseynov Muxtar
Published: April 2024

The importance of creating specialized production sites to meet the needs of shipbuilding and ship repair enterprises of Azerbaijan in metal billets is substantiated. Technical, technological and organizational measures for the specialization of the existing production sites of Baku Steel Company LLC for the production of shipbuilding steels are recommended. The ways of mastering the production of continuously cast billets and sheet-rolling technologies from shipbuilding steels are shown.For this purpose, the need to install a continuous casting machine (CCM) in Baku Steel Company LLC is substantiated and the advantages of manufacturing steel billets on this machine are shown. It is determined that in order to reduce the overall dimensions of the caster, its radius of curvature should be 10.2 m. It is shown that the rational value of the radius of curvature reduces the probability of defects on the blanks during crystallization and makes it possible to obtain blanks of various profiles.It is shown that the combined use of EMF and hydrocarbons can reduce the defects of blanks by 2-3 times, increase the zones of equiaxial crystals by 50-80%, significantly reduce axial porosity and liquation, increase the casting speed of liquid steel by 20-30% and reduce the metal consumption of equipment by 2 times. The introduction of technologies for electromagnetic mixing and vacuuming of liquid steel makes it possible to expand the production of alloy steels for the needs of shipbuilding and ship repair enterprises.
Analyzing the Effect of Temperature on Alloy Steel Forging Simulation Using Finite Element Simulation
Authors: Efa Dame Alemayehu , Lemu Hirpa G. , Gutema Endalkachew Mosisa , Gopal Mahesh
Published: April 2024

The goal of this research is to examine the influence of temperature affects the forging of a rectangular billet of AISI 4120 alloy steel using the 3D Deform version 11 software. The simulation was performed with 0.3 coefficient of friction on a metal forming (lubricated) process and the part is intended for application in aerospace and oil and gas industries. Three modules of deform software were defined to execute the simulation: pre-processing, simulation, and post-processing. The pre-processing in forging employed standard data— material selection, billet drawing, top and bottom dies design, meshing and simulation control. After 120 steps, the post-process estimation of deformation temperature, effective strain and stress, total velocity, and total displacement were obtained on the billet of material at temperatures of 800o C, 1000o C, and 1200° C. The results show that when forging temperatures climb, effective strain and stress decrease, total displacement and velocity decrease, and the final temperature increases.

Association of Types of Meal Skipping with Cardio-metabolic Risk Factors in Korean Adults: The 7th Korea National Health and Nutrition Examination Survey (2016–2018)
Authors: Tae Jiyoon , Park Junhee , Cho Hyeonjin , Shin Dong Wook
Published: April 2024

Background: This study aimed to examine the effects of different types of skipped meals on cardiometabolic risk factors (CMRF) in Korean adults.Methods: We analyzed 14,062 adults from the Korea National Health and Nutrition Examination Survey conducted between 2016 and 2018. The irregularity of breakfast, lunch, and dinner consumption was assessed using 24-hour recall data, and we categorized the habit of skipping regular meals into eight types. Multiple linear regression was used to estimate the association between each type of meal skipping and the CMRF. We also presented the estimated effects of individual types of meal skipping on the CMRF based on their predicted values and mean differences.Results: Korean adults tended to have irregular meal consumption habits when they had one or more of the following characteristics: female sex, under the age of 50 years, middle-high to high household income, high school or college or higher education levels, alcohol consumption, and current smoking. Compared to regular eaters, we have observed significantly higher total cholesterol in the following types of meal skipping: irregular breakfast (IB) (P<0.001), irregular lunch (P=0.005), irregular breakfast and lunch (IBL) (P=0.001), irregular breakfast and dinner (P=0.001); higher low-density lipoprotein-cholesterol in IB (P=0.009); higher triglyceride in IB (P=0.005) and IBL (P=0.034); and higher fasting glucose in IB (P=0.046).Conclusion: Different types of meal skipping were associated with CMRF. Regular breakfast and lunch consumption should be emphasized to prevent and manage cardiometabolic disorders. However, skipping dinner showed no significant association with CMRF.
Building welcoming and inclusive congregations: Biblical hospitality as a theological paradigm
Authors: Shirley Timothy W. , Nel Malan , Meyer Esias E.
Published: April 2024

This article addresses the question, ‘how can congregations that exhibit prejudice toward LGBTQQIA+ persons (different expressions of nonheterosexuality), overcome bias and discriminatory practices to become missionally holistic, hospitably welcoming, and inclusive of these individuals?’. The answer can be found in engaging an alternative biblical hermeneutic that emphasises the socio-historical context of a given narrative, thus creating a broader and deeper understanding of the principle of biblical hospitality as a fundamental theological premise inherent within the Judeo-Christian scriptures. Accomplishing transformative change demands intentionality by clergy equipped to engage the issues effectively. Pastoral ministers must cultivate the exegetical skills needed to guide local missional churches towards greater inclusivity, with the goal of creating more hospitably welcoming and inclusive faith communities.Intradisciplinary and/or interdisciplinary implications: This article engages a dialogue between biblical and practical theology as missional praxis supporting congregational development as ecclesial reformational transformation to enable local churches to become hospitably welcoming and inclusive.
Drug holiday effect on osteoporosis: a narrative review of the current literature
Authors: Velitsikakis Paraskevas Asimakis , Psochias Philippos , Kopanos Stylianos , Perisynakis Nikolaos , Georgios Giovanidis
Published: April 2024

Bisphosphonates are most common drugs used in the treatment of osteoporosis being effective in reducing fracture risk. Although these drugs are quite safe and tolerable drugs, there has been an association with severe adverse effects after a prolonged period of use. The idea of ‘drug holiday’ is becoming a trend, because of the way these drugs work, absorbed by the bone and continuing the exertion of an antiresorptive effect even after discontinuation, meaning that the patient continues to benefit from anti-fracture efficacy, while the risk of side effects is reduced. Discontinuation of bisphosphonates should be considered in patients who have been treated for more than 5 years with alendronate or more than 3 years with risedronate or zoledronic acid, and reassessment should be done every 1 to 3 years if there is no new adverse event in the meantime.
Ultrasound-guided injection versus landmark-guided injection using corticosteroids for the treatment of lateral epicondylitis
Authors: Ghandour Tarek M
Published: April 2024

Purpose

To compare the clinical results of corticosteroid injection using landmark-guided injection (LMGI) and ultrasound-guided injection (USGI) techniques.

Patients and methods

We injected corticosteroids in 55 patients with extraarticular tennis elbow using LMGI and USGI techniques. All patients suffered from lateral elbow pain for more than 3 months with a tender point on the lateral epicondyle. This pain was exaggerated by wrist extension and specific physical activity. For postprocedural evaluation, in a randomized controlled assessor-blinded clinical trial, visual analog score (VAS), pain-free grip strength (PFGS), and the Nirschl staging system were assessed at 1, 6, 24 weeks, and 12 months.

Results

Only 48 participants were included in the final analysis (seven were excluded). Preoperatively, the average VAS scores, tenderness over lateral epicondyle, PFGS values, and Nirschl stages were almost the same (P=0.620, 0.505, 0.784, and 0.455). After 1 week of injection, there was no significant difference noticed in the VAS for pain at rest, tenderness during palpation, the PFGS and Nirschl stages between group 1 and group 2 (P=0.947, 0.724, 0.484, and 0.677, respectively). A statistically significant difference between the two groups was observed from 6 to 48 weeks. At the final follow-up, group 2 had a statistically significant better outcome when compared to group 1 (P<0.05).

Conclusion

USGI had a better long-term outcome than LMGI in the treatment of lateral epicondylitis.

Introduction

The intracystic injection of methylprednisolone acetate, curettage with bone grafting, osteoinductive treatments employing demineralized bone matrix, and intramedullary fixation with flexible nails are being used to treat unicameral bone cysts (UBC) in children. The purpose of this study was to assess the functional results of elastic stable intramedullary nails for symptomatic UBC with or without a fracture.

Methods

From March 2012 to March 2022, 18 patients with UBC were treated with intramedullary flexible nails. Pathological fractures were present at the cyst site in 6 individuals. 12 patients had discomfort and swelling in the afflicted extremity. Cysts were found in the humerus in 13 (72%) patients and the femur in 5 (28%) cases. The average age of the patient at the time of surgery was 7.8 (6–12 years), and the average follow-up period was 16 months. The Capanna et al. criteria were used to do the radiographic evaluation.

Results

According to radiological evaluation by Capanna et al., 5 cysts healed completely (Stage I), 5 cysts healed with residual radiolucent areas visible on radiographs that were less than 3 cm in size (Stage II), and 7 cysts healed with residual radiolucent areas that were visible on radiographs that were larger than 3 cm in size (Stage III). An infection at the surgery site affected one patient. A 12 (60%) patients had their implants removed.

Conclusion

Elastic stable intramedullary nailing promotes early stabilization, enables early mobilization, eliminates the need for a plaster cast, and reduces the occurrence of a pathological fracture with early return to functional activity.

Abnormalities of the inferior vena cava (IVC) and its tributaries are rare anomalies detected more frequently by computed tomography scans with intravenous contrast. Its importance lies in identifying them by the possible clinical and surgical implications. They originate from the persistence or regression of the three embryonic veins (posterior cardinal, subcardinal, and supracardinal) and their anastomosis. There are three cases, the first with double IVC type I, which has a prevalence of 0.2%–3%. The second case has a left vena cava, which has a 0.2%–0.5% prevalence. The third case is with retroaortic left renal vein, which has a prevalence of 3.4%.

Background:

Acute upper-limb ischemia (AULI) is a sudden loss of perfusion to the affected limb. The annual incidence of AULI has been reported as 1.3 cases/100,000 patients. It can be due to vaso-occlusive or vasospastic disorders. It is often the result of thromboembolic disease, trauma, or iatrogenic factors. AULI has multiple modalities of treatment including surgical and nonsurgical options.

Materials and Methods:

Our study is a retrospective study where patients who have been conservatively treated at a single center between January 2015 and January 2018 were followed up for 5 years.

Results:

The analysis included 31 patients (61.3% males), with a mean age of 57 years. Only three patients presented within 6 h, and 16 patients presented more than 12 h after symptom onset. Of the 31 patients, 19% had a cardiac source of embolus, 65% had arterial thrombosis, and 16% had other etiologies. The axillary and brachial arteries were noted to be the most affected sites. All the patients underwent conservative management with anticoagulation. Results of this study showed that patients had amputation-free survival with improvement in clinical symptoms and functional outcomes at 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years. None of the patients required a surgical intervention for revascularization. At the end of 5 years of follow-up, two patients underwent partial amputations of one or more fingers, and limb salvage was achieved in all the patients. Most of the patients improved in terms of limb functionality from Grade 3 or Grade 4 at the time of presentation to Grade 1 according to functionality grading.

Conclusion:

Patients treated with conservative management for AULI have good amputation-free survival and good functional outcomes after 5 years as per our study.

Cholesterol is an important component of plasma membranes and participates in many basic life functions, such as the maintenance of cell membrane stability, the synthesis of steroid hormones, and myelination. Cholesterol plays a key role in the establishment and maintenance of the central nervous system. The brain contains 20% of the whole body’s cholesterol, 80% of which is located within myelin. A huge number of processes (e.g., the sterol regulatory element-binding protein pathway and liver X receptor pathway) participate in the regulation of cholesterol metabolism in the brain via mechanisms that include cholesterol biosynthesis, intracellular transport, and efflux. Certain brain injuries or diseases involving crosstalk among the processes above can affect normal cholesterol metabolism to induce detrimental consequences. Therefore, we hypothesized that cholesterol-related molecules and pathways can serve as therapeutic targets for central nervous system diseases. Intracerebral hemorrhage is the most severe hemorrhagic stroke subtype, with high mortality and morbidity. Historical cholesterol levels are associated with the risk of intracerebral hemorrhage. Moreover, secondary pathological changes after intracerebral hemorrhage are associated with cholesterol metabolism dysregulation, such as neuroinflammation, demyelination, and multiple types of programmed cell death. Intracellular cholesterol accumulation in the brain has been found after intracerebral hemorrhage. In this paper, we review normal cholesterol metabolism in the central nervous system, the mechanisms known to participate in the disturbance of cholesterol metabolism after intracerebral hemorrhage, and the links between cholesterol metabolism and cell death. We also review several possible and constructive therapeutic targets identified based on cholesterol metabolism to provide cholesterol-based perspectives and a reference for those interested in the treatment of intracerebral hemorrhage.

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.
Age-related driving mechanisms of retinal diseases and neuroprotection by transcription factor EB-targeted therapy

Published: April 2024

Retinal aging has been recognized as a significant risk factor for various retinal disorders, including diabetic retinopathy, age-related macular degeneration, and glaucoma, following a growing understanding of the molecular underpinnings of their development. This comprehensive review explores the mechanisms of retinal aging and investigates potential neuroprotective approaches, focusing on the activation of transcription factor EB. Recent meta-analyses have demonstrated promising outcomes of transcription factor EB-targeted strategies, such as exercise, calorie restriction, rapamycin, and metformin, in patients and animal models of these common retinal diseases. The review critically assesses the role of transcription factor EB in retinal biology during aging, its neuroprotective effects, and its therapeutic potential for retinal disorders. The impact of transcription factor EB on retinal aging is cell-specific, influencing metabolic reprogramming and energy homeostasis in retinal neurons through the regulation of mitochondrial quality control and nutrient-sensing pathways. In vascular endothelial cells, transcription factor EB controls important processes, including endothelial cell proliferation, endothelial tube formation, and nitric oxide levels, thereby influencing the inner blood-retinal barrier, angiogenesis, and retinal microvasculature. Additionally, transcription factor EB affects vascular smooth muscle cells, inhibiting vascular calcification and atherogenesis. In retinal pigment epithelial cells, transcription factor EB modulates functions such as autophagy, lysosomal dynamics, and clearance of the aging pigment lipofuscin, thereby promoting photoreceptor survival and regulating vascular endothelial growth factor A expression involved in neovascularization. These cell-specific functions of transcription factor EB significantly impact retinal aging mechanisms encompassing proteostasis, neuronal synapse plasticity, energy metabolism, microvasculature, and inflammation, ultimately offering protection against retinal aging and diseases. The review emphasizes transcription factor EB as a potential therapeutic target for retinal diseases. Therefore, it is imperative to obtain well-controlled direct experimental evidence to confirm the efficacy of transcription factor EB modulation in retinal diseases while minimizing its risk of adverse effects.
Quality of life scales in pigmentary disorders

Pigmentary disorders, especially vitiligo and melasma, are cosmetically disfiguring and have a profound impact on life quality. Various quality of life tools and questionnaires have been devised in order to objectively quantify this psychosocial morbidity, which can guide towards more comprehensive patient management. These include generic measures, dermatology-specific measures, and disease-specific measures. The latter are mostly developed for melasma and vitiligo. Most of these tools measure the impact on life quality across various psychosocial domains, particularly feelings of embarrassment about appearances and societal stigma. The present review consolidates the available literature on quality of life scales used in pigmentary disorders.
