Historia del pensamiento económico y sus principales corrientes de la era preclásica
Authors: De La Hoz Suárez Betty Auxiliadora
Published: December 2023

La preocupación por el entendimiento de los procesos económicos dentro de las organizaciones y las sociedades se remonta a Grecia y Roma en la época de la civilización. El presente artí­culo analiza el pensamiento preclásico de la economí­a, cuya escuela abarca tres corrientes del pensamiento: los grandes pensadores de la edad media, los mercantilistas y los fisiócratas, desde una perspectiva racional. Se analiza cada una de dichas corrientes y su contribución en el entendimiento de la economí­a. Se trata de un estudio cualitativo e histórico de tipo descriptivo, fundamentado en fuentes documentales tales como: libros, enciclopedias, informes, artí­culos cientí­ficos, y recopilaciones de ideas de ilustres intelectuales sobre el pensamiento de la economí­a en la época preclásica. Los resultados muestran que los pensadores medievales observaron los hechos económicos desde una óptica ética, y trataron de juzgar desde el punto de vista moral, cuestiones como el tipo de interés, el precio justo, las relaciones laborales, entre otras; los pensadores mercantilistas recomendaron a los gobernantes el impulso de medidas polí­ticas que conlleven al enriquecimiento de la nación; y los pensadores fisiócratas consideraban que la riqueza circulaba entre tres grupos sociales, a saber, la clase productiva, la clase estéril y los propietarios y que es el Estado quien debe mantener dicho orden natural. Se concluye que, el pensamiento económico desde una perspectiva racional de las teorí­as no tiene la intención de buscar recoger la historia para luego reproducir viejas ideas, sino más bien, preparar el camino para crear nuevas que van en avance; y es la evolución misma de estas ideas la que contribuye a generar transformaciones en las polí­ticas sociales y económicas.

Authors: Gutierrez Antonio , Copaz Arandia Rosaly Alodia
Published: December 2023

Procurar elegir un modelo de gestión del conocimiento es un acto complejo, ya que existen diversos, por lo que probablemente va a depender de las lí­neas de investigación que considere adecuado para su trabajo investigativo. Este artí­culo tiene como objetivo analizar conceptualmente los modelos de gestión del conocimiento, a objeto de establecer un marco referencial para futuras investigaciones. Es por lo que el presente artí­culo se caracteriza por ser una investigación de tipo descriptiva que parte por una revisión teórica de artí­culos cientí­ficos de distintas bases de datos académicos para utilizar criterios de inclusión y exclusión acorde al objetivo de la investigación. Se concluye que para las organizaciones son provechosos los distintos modelos que hay en la actualidad, pero requieren de modelos con similares objetivos y caracterí­sticas, como ser con enfoque empresarial, educativo o ambos, de este modo los trabajos cientí­ficos pueden ser mejor aprovechados por los investigadores y por las instituciones.

Published: December 2023

AIM: Banjar District is included in the top 3 of highest maternal mortality rates in South Kalimantan, Indonesia. The purpose of the study is to analyze the relationship between accessibility (distance, time, and transportation) with the incidence of maternal mortality in Banjar District.
METHODS: The study is an observational analysis using a case–control approach with a retrospective. The population was mothers who gave birth in the Banjar district on January 2015−December 2018. Criteria for inclusion of cases are mothers who experience death during pregnancy, childbirth or within 42 days before the end of the pregnancy period recorded in 2015−2018 at the Health Office and births at health facilities in Banjar District, which is represented by the family who knows the best about the mother’s condition, while controls are respondents who do not died in the same year. Sample for case group is 25, by taking the comparison case: control 1:2, then, the sample size of the control group is 50. Statistical test uses Chi-square test.
RESULTS: The results show that there is the relationship between transportation (p = 0.034) and distance (p = 0.035) with the incidence of  maternal mortality with Odds ratio (OR) 3.58 and 3.27. However, there is no relationship between time (p = 0.118) with the mortality of maternal.
CONCLUSION: Increasing the accessibility of health services can reduce maternal mortality, one of which is the provision of transportation to bring mothers closer to health facilities.

Published: December 2023

In support of ongoing taxonomic work on the large and complex flowering plant genus Erica (Ericaceae), we document nineteen pairs of homonyms representing currently used illegitimate names. We provide replacements for thirteen names and new typifications for five. We relegate five names to synonymy: Erica aemula Guthrie & Bolus under Erica distorta Bartl.; Erica armata Klotzsch ex Benth. under Erica umbrosa H. A. Baker; Erica capensis T.M. Salter under Erica turbiniflora Salisb.; Erica lanata Andrews under Erica flaccida Link; and Erica tomentosa Salisb. under Erica velutina Bartl. Finally, we suggest conservation of Erica aristata Andrews. The new names are: Erica adelopetala E.C. Nelson & E.G.H. Oliv. replacing Erica insignis E.G.H. Oliv.; Erica bombycina E.C. Nelson & Pirie replacing Erica niveniana E.G.H. Oliv.; Erica concordia E.C. Nelson & E.G.H. Oliv. replacing Erica constantia Nois. ex Benth.; Erica didymocarpa E.C. Nelson & E.G.H. Oliv. replacing Erica rugata E.G.H. Oliv.; Erica galantha E.C. Nelson & E.G.H. Oliv. replacing Erica perlata Benth.; Erica mallotocalyx E.C. Nelson & E.G.H.

Assessing ‘non-destructive’ DNA extraction method in small crustaceans kept in wet collections
Authors: Bernardes Samuel C. , von Rintelen Thomas , Alexander Serena , Lorenz Fiona , von Rintelen Kristina
Published: December 2023

Specimens in natural history museums are a valuable resource for biological research, such as taxonomic, biodiversity or evolutionary studies. However, the quality of DNA and even morphological characters can decrease over time, depending on previous fixation and long-term preservation methods. In recent years, advances in DNA extraction and sequencing techniques have allowed researchers to obtain DNA from museum specimens, even when the DNA was very fragmented. Extraction methods should ideally be morphologically non-destructive, leaving diagnostic characters intact for future taxonomic studies. Here, we assess whether the whole-body extraction widely used for several taxa would be destructive for small crustaceans kept in wet collections. We extracted the DNA from over 70 small (1-3 cm) and relatively fragile shrimps collected during the last 30 years by using: i) a piece of abdominal tissue and ii) from the entire remaining body of the animal. We photographed several samples before and after the lysis, focusing on taxonomically relevant characters. Although DNA concentration was higher in the whole-body extractions, the presence of intact DNA was not correlated to the amount of lysed tissue. The resulting genomic libraries had little to no difference in yield. The taxonomically relevant characters were primarily preserved in larger specimens, whereas smaller specimens (< 1.5 cm) became too fragile to handle or were damaged. We conclude that this method must be carried out carefully in smaller crustaceans, depending on size and taxon. We advise against using it with type specimens as the advantages do not outweigh the risks. Our experiment may provide future research with quantitative and qualitative evaluations to help scientists weigh their decisions when extracting DNA from wet collection material.

Published: December 2023

In this study, a new species named Scutiger luozhaensissp. nov. is described from Luozha, southern Tibet, China. Genetic analysis based on two mitochondrial genes 16S rRNA and COI and the nuclear gene RAG1 revealed that the new species belongs to an independent phylogenetic clade close to S. gongshanensis and S. nyingchiensis and shares no RAG1 haplotype with other species. Morphological comparisons based on examined specimens and literatures indicated that it can be diagnosed from congeners by the following combination of characters: (1) body moderate, male body length 47.0–67.2 mm (n = 13), female body length 49.8–66.2 mm (n = 8); (2) maxillary teeth and budding absent; (3) numerous tiny dense nuptial spines present on dorsal surface of fingers I, II and inner surface of finger III of males in breeding condition with similar size; (4) spine patches on belly of males in breeding condition absent; (5) spines on inner surface of forearm and upper arm of males in breeding condition absent; (6) small patches of black spines present near armpit of males in breeding condition absent; (7) adult males without vocal sac; (8) some large warts and tubercles on dorsum gathered into short skin ridges with several spines present on top; (9) space between upper eyelids wider than upper eyelids; (10) spots or irregular cross bands on limbs absent; (11) webbing between toes rudimentary; (12) coloration of dorsal body olive brown to bronze.

Advanced Practice Psychiatric Nursing: the Need for a Blended Role
Authors: Moller Mary , Haber Judith
Published: December 2023

The purpose of this article is to advance the debate about whether the NP or the CNS alone should be the predominant advanced practice role in psychiatric-mental health nursing, or whether a blended advanced practice role is more appropriate for meeting the needs of services in the 21st century. We argue that a blended role is most appropriate in moving the psychiatric-mental health nursing specialty forward. The blended advanced practice role retains the excellence of our psychosocial tradition and incorporates the biological perspective of the future.
« Adana (2) » : l’agglomération d’Adana : étalement urbain contraint et recomposition récente du tissu

Published: December 2023

Le principal pôle urbain du département, l’agglomération d’Adana, une des plus importantes de Turquie, voit sa croissance démographique se réduire depuis quelques années. Pourtant la dynamique d’étalement alimentée par les politiques de renouvellement urbain se poursuit. Alors que la conservation des héritages de l’Adana multiconfessionnelle d’avant les années 1920 demeure timide, l’agglomération se développe selon des modalités et sous des formes très banales, à l’image de toutes les autres villes de Turquie.
L’impact du confinement sur les pratiques religieuses : l’expérience d’élèves dans un établissement catholique
Authors: Didier-Fèvre Catherine
Published: December 2023

La pandémie de Covid-19 a mis à l’épreuve les pratiques religieuses d’étudiants de classes préparatoires littéraires d’un établissement privé catholique français. Si certains d’entre eux ont cessé de pratiquer, d’autres ont mis en œuvre des dispositifs pour pallier l’absence de rituels, les amenant parfois à des prises de positions radicales. Ces évolutions spirituelles comme ces positionnements politiques sont propres à un âge de transition pendant lequel le jeune se construit en tant qu’individu. Le groupe classe comme le culte organisé dans un cadre scolaire ont joué un rôle fédérateur et tenu une place centrale dans le processus de socialisation secondaire qui caractérise tant ce type d’études supérieures.
Le « temps des témoignages » : Péguy au point de cristallisation
Authors: Jeannelle Jean-Louis
Published: December 2023

En 1909, Péguy dénonce un repli collectif, qui se trouve coïncider avec son entrée dans l’âge où il aspire à embrasser sa vocation d’écrivain. Or il écrit aussi au seuil du basculement dans l’ère des catastrophes historiques. Péguy n’a guère écrit de témoignages au sens strict, mais ses Cahiers et son œuvre même accueillent tous les enjeux (religieux, juridiques, épistémiques) du rapport de ce genre à la question de son historicité. C’est pourquoi il se situe au point de cristallisation du témoignage comme genre, en contribuant à penser la restitution d’une vérité vécue dont se porte garant un sujet par sa parole et son écriture.
La contribution des épreuves projectives à la compréhension de la dynamique du fonctionnement psychique : une exigence éthique
Authors: Verdon Benoît
Published: December 2023

La question de la contribution des méthodes projectives à la démarche diagnostique est clinique et scientifique ; elle est aussi éthique car elle interroge le sens de nos actes, pour penser leur justesse et notre responsabilité. Rappelant les fondements des méthodes projectives comme situation clinique exigeant rigueur et souplesse pour respecter et entendre la complexité dynamique du fonctionnement psychique, l’auteur articule la démarche diagnostique au contexte d’exigence de transparence, de défiance du savoir expert porté par les professionnels. Évoquant des situations de dérive évaluative et diagnostique, empreintes de contrôle, de banalisation, de scientisme ou de séduction, il rappelle l’importance de la valeur médiatrice des méthodes projectives pour intéresser le sujet à son fonctionnement psychique.
La troisième psychose
Authors: Rakova-Carron Liuba , Kapsambelis Vassilis
Published: December 2023

Les termes de psychose, de schizophrénie et d’autisme ont connu des périmètres variables au fil des décennies. Notre étude a pour but d’établir les différences entre les psychoses de l’adulte (schizophrénies ou pas), et les syndromes psychotiques observés à l’âge adulte chez de patients qui, enfants, avaient été diagnostiqués comme psychotiques (ce qui entrerait aujourd’hui dans les troubles du spectre autistique). Cette différenciation se fait à partir de critères psychopathologiques et projectifs, et tend à montrer que ces adultes, anciens « enfants psychotiques », présentent des modalités de fonctionnement mental qui diffèrent, aussi bien des fonctionnements incluant un objet de délire (psychoses délirantes) que des fonctionnements utilisant un objet-fétiche (psychoses froides et certains aspects des fonctionnements limite).
Un cas de tueur en série célèbre : et si le crime était dans le Rorschach ?
Authors: Husain Odile , Saint-Laurent Nancy , Lepage Mariette
Published: December 2023

Les auteurs se penchent sur le Rorschach historique (1975) d’un tueur en série notoire, à l’aide de l’analyse psychodynamique du discours centrée sur les axes organisateurs du fonctionnement psychique (relation d’objet, limites, Moi, angoisse, mécanismes de défense, processus de pensée). Ils suivent tout particulièrement le parcours de la pulsion agressive dans ses nombreuses manifestations, d’abord à l’aide d’analyses empiriques, puis par la méthode d’analyse du discours. Ils aboutissent au constat que ce Rorschach est peuplé par les fantaisies meurtrières du sujet.

Les espaces de coworking : un levier de régénération des territoires en dehors des métropoles ?
Authors: Leducq Divya
Published: December 2023

La diffusion géographique des espaces de coworking (ECW) soulève la question des apports possibles de ces nouveaux lieux à des espaces non métropolitains. Les ECW sont-ils en mesure de contribuer à la résilience architecturale, économique et sociale des territoires « périphériques » ? Quels rôles les différents acteurs du coworking – créateurs-managers, usagers et collectivités territoriales – jouent-ils dans cette possible revitalisation ? Notre hypothèse est que l’apparition de ces nouveaux lieux peut contribuer à la revitalisation des territoires hors-métropoles, mais que parallèlement cette contribution reste marginale et proportionnelle à la taille et l’ancienneté de l’ECW. Trois pistes de cette revitalisation sont pointées : la réhabilitation des bâtiments et friches, la contribution au développement du tissu économique local et enfin les liens sociaux et communautaires engendrés par la présence d’un ECW.
Le tiers-lieu : un nouvel avatar du développement territorial ?
Authors: Moyart Laurence , Pecqueur Bernard
Published: December 2023

L’émergence des tiers-lieux (TL) est un phénomène rapide et récent bien que le concept soit né aux États-Unis il y a plus de trente ans. Il s’inscrit dans un processus historique long d’apparition de système productifs localisés (SPL), soit d’inspiration italienne avec les districts industriels (DI), soit d’inspiration américaine sur le modèle des clusters. Ces structures nées des années 1970-1980 constituent un premier tournant territorial. L’avènement des TL en grand nombre porte des enjeux forts et fait suite au cumul de plusieurs facteurs à dimension mondiale (accélération de la crise climatique, crise financière de 2008, crise sanitaire depuis 2019). Ces évènements inaugurent, après une période d’approfondissement de la mondialisation, un deuxième tournant territorial. Le premier tournant a été dominé par la forme DI ou SPL, le deuxième semble s’inaugurer autour d’une forme voisine mais pas identique d’intégration systémique, production et consommation, de type TL. Celui-ci serait l’avatar le plus récent du développement territorial. L’article montre que l’industrie wallonne, très tributaire du modèle fordiste en déclin, n’a pas vraiment pris le premier virage mais, avec la réalisation du plan Creative Wallonia , s’engage depuis une dizaine d’années dans ce deuxième tournant environnemental et sociétal.
A prognostic prediction model for ovarian cancer using a cross-modal view correlation discovery network
Authors: Wang Huiqing , Han Xiao , Ren Jianxue , Cheng Hao , Li Haolin , Li Ying , Li Xue
Published: December 2023

Ovarian cancer is a tumor with different clinicopathological and molecular features, and the vast majority of patients have local or extensive spread at the time of diagnosis. Early diagnosis and prognostic prediction of patients can contribute to the understanding of the underlying pathogenesis of ovarian cancer and the improvement of therapeutic outcomes. The occurrence of ovarian cancer is influenced by multiple complex mechanisms, including the genome, transcriptome and proteome. Different types of omics analysis help predict the survival rate of ovarian cancer patients. Multi-omics data of ovarian cancer exhibit high-dimensional heterogeneity, and existing methods for integrating multi-omics data have not taken into account the variability and inter-correlation between different omics data. In this paper, we propose a deep learning model, MDCADON, which utilizes multi-omics data and cross-modal view correlation discovery network. We introduce random forest into LASSO regression for feature selection on mRNA expression, DNA methylation, miRNA expression and copy number variation (CNV), aiming to select important features highly correlated with ovarian cancer prognosis. A multi-modal deep neural network is used to comprehensively learn feature representations of each omics data and clinical data, and cross-modal view correlation discovery network is employed to construct the multi-omics discovery tensor, exploring the inter-relationships between different omics data. The experimental results demonstrate that MDCADON is superior to the existing methods in predicting ovarian cancer prognosis, which enables survival analysis for patients and facilitates the determination of follow-up treatment plans. Finally, we perform Gene Ontology (GO) term analysis and biological pathway analysis on the genes identified by MDCADON, revealing the underlying mechanisms of ovarian cancer and providing certain support for guiding ovarian cancer treatments.

Published: December 2023

Introduction

The pandemic has led to notable psychological challenges among healthcare professionals, including nurses.

Objective

Our aims of this study were to assess insomnia and nightmare distress levels in nurses and investigate their association with mental resilience.

Methods

Nurses participated in an online survey, which included the Nightmare Distress Questionnaire (NDQ), Brief Resilience Scale (BRS) and Athens Insomnia Scale (AIS). Demographic information, such as age, professional experience and gender, was also collected.

Results

The study included 355 female and 78 male nurses. Findings revealed that 61.4% had abnormal AIS scores, 7% had abnormal NDQ scores and 25.4% had low BRS scores. Female nurses had higher AIS and NDQ scores but lower BRS scores compared to males. BRS demonstrated negative correlations with both AIS and NDQ. Multiple regression analysis indicated that NDQ accounted for 24% of the AIS variance, with an additional 6.5% explained by the BRS. BRS acted as a mediator, attenuating the impact of nightmares on insomnia, with gender moderating this relationship.

Conclusions

Nursing staff experienced heightened sleep disturbances during the pandemic, with nightmares and insomnia being prevalent. Nightmares significantly contributed to insomnia, but mental resilience played a vital role in mitigating this effect. Strategies are warranted to address the pandemic's psychological impact on nursing professionals.
Impacts of cyanide in gold mining and cyanide removal methodologies in liquid waste from gold processing
Authors: Freitas Juliana , Horta Daniela
Published: December 2023

Cyanide is used in several industries but is widely used for gold extraction due to its ability to complex and stabilize gold ions. The waste generated from this process is of great volume because of low ore grades that requires more processing areas. Also, it is highly toxic due to cyanide being a contaminant of animal life and the environment. The mining sector can recycle the effluents generated in their processes, however, this can affect the gold extraction and treatment methods. There are legal laws that define cyanide levels in effluents for disposal in water bodies. Methodologies for reaching these levels include oxidation degradation processes, physical-chemical, biological processes, adsorption, photocatalysis, among others. In this present review, the use of cyanide in gold mining and some of these methodologies for removing cyanide in effluents generated by gold processing are evaluated.
Crack bifurcation behavior of coarse-grained copper under cyclic torsion combined with axial static loading
Authors: Yue Liu Jin , Hua Li Rong , Chen Ji
Published: December 2023

Because the growth behaviors of fatigue cracks are crucial for the safe assessment of structural components, the crack propagation behaviors of coarse-grained copper (CG Cu) subjected to cyclic torsion combined with different axial static stresses were studied. The crack bifurcation behavior is related to the strain amplitude applied. When the strain amplitude is lower, both the type and the magnitude of axial stress have no significant effect on the direction in which the primary crack branches, which is mainly determined by the position of the maximum normal plane. However, when the strain amplitude is higher, the bifurcated crack deviates visibly from the maximum normal plane, which can be attributed to the high degree of plastic deformation and microcracks caused by slip bands along longitudinal direction.
The non-consumptive economic value of wildlife: the case of three cetacean species

Published: December 2023

The conservation of wildlife is one of the most pressing issues in the current times, but wildlife conservation economic values have often been largely ignored due to an absence of market prices, as setting an economic value on biodiversity or whole ecosystems can be challenging. Nevertheless, valuing wildlife can be of great significance to improve decision-making in the conservation field, as it can provide a complementary perspective based on economic principles. Whale-watching provides an opportunity for the economic valuation of wildlife. Specifically, it offers a framework in which the economic revenue allows the economic valuation of the targeted cetaceans to be estimated through the direct and indirect expenditure of the tourists who purchase whale-watching tours. Here, we performed an economic analysis based on population abundances of the three main species targeted by the whale-watching companies in the Strait of Gibraltar (Spain): long-finned pilot whales (Globicephala melas), common dolphins (Delphinus delphis) and killer whales (Orcinus orca). These species generated a total annual income of €4,089,056, €1,876,833, and €505,389, respectively, and each individual would generate an average of €14,048, €951, and €36,099 each year, respectively. Incorporating life expectancy, this corresponded to a total population value of €112,426,185, €16,685,147, and €19,171,107, respectively, over their lifetime. These values provide an idea of the potential contribution of cetaceans to the local economy but only represent their non-consumptive value based on tourism. Our results reinforce the idea that a sustainable, high-quality whale-watching culture, under ACCOBAMS High-Quality Whale-Watching requirements, should be promoted to ensure a sustainable industry, stable economic income and the viability of cetacean populations in the Strait of Gibraltar.

Published: December 2023

The spider crabs of the genus Pisa Leach, 1814 (Epialtidae: Pisinae) are reviewed in this study based on morphological and molecular data (16S and COI genes). From these results, a new genus, Afropisa n. gen., is established for the clade composed of Pisa carinimana Miers, 1879, Pisa calva Forest and Guinot, 1966 and Pisa sanctaehelenae Chace, 1966 based on carapace morphology, rostrum, pterygostomian tubercles and male gonopod 1. Additionally, Lissa chiragra (Fabricius, 1775) is transferred to Pisa based on morphological (adults and larvae) and molecular evidence. Furthermore, the status of Pisa hirticornis (Herbst, 1804) is discussed and clarified. The phylogenetic relationships between several Pisinae Dana, 1851 genera, as revealed by molecular data, are discussed. An illustrated identification key of eastern Atlantic and Mediterranean species of Pisinae is provided.
Diel cycle of two recurrent fish sounds from mesophotic coral reefs
Authors: Raick Xavier , Collet Pierre , The Pole Consortium Under , Lecchini David , Bertucci Frédéric , Parmentier Eric
Published: December 2023

Mesophotic coral ecosystems (MCEs) are the deepest part of tropical coral reefs, ranging from depths of 30 to over 170 m. Despite their significance, MCEs remain largely unexplored due to the challenges associated with accessing these depths. However, the application of passive acoustic monitoring methods (PAM) is a suitable approach for studying fish communities within these unique habitats. In French Polynesia, recent PAM studies have unveiled a higher occurrence of frequency-modulated fish sounds in MCEs than in shallower reef environments. This study aims to further enhance our understanding of fish sounds in MCEs by examining their diel patterns, focusing specifically on the two most abundant frequency-modulated fish sounds that were recorded at depths of 60 and 120 m at six Polynesian islands. Both sound types occurred predominantly during the beginning and the end of nocturnal periods. The presence and abundance of these sounds exhibited variation between the islands, highlighting potential regional disparities in vocal activity or the bathymetric distribution of the sound-producing species. By characterizing the diel cycles and bathymetric differences in relation to their geographical distribution, this study offers preliminary insights into identifying the potential sound-producing species.

Published: December 2023

In the current research, titanium carbide (TiC) is used to reinforce the aluminium alloy (AA 6063) in stir-cast hybrid composites at concentrations of 5, 10, and 15 weight percent together with 3 weight percent of graphite. The application of this developed composite is mainly used for automobile suspension parts. The portrayal of characters was performed, and the mechanical properties of the fabricated samples were investigated. Composites with different TiC weight percentages have their mechanical properties, including hardness, tensile strength, compressive strength, and flexural strength, measured and assessed. The results are shows that AA 6063 alloy with 3 wt. percentage of graphite with an increasing weight percentage of TiC composites are better in the mechanical property. The hardness of the AA 6063 alloy composites is greater than that of the base matrix alloy. The tensile strength of Al 6063 alloy composites has been reported to grow with increasing TiC particle content and to be significantly higher than the strength of the matrix alloy. Also, the SEM microstructure images clearly shows that 15 weight percentage of TiC with 3 weight percentage of Graphite shows the maximum distribution in the matrix.

Authors: Zhang Qiang , Li Yuhuan , Chang Xiaozan
Published: December 2023

Background:

Traumatic brain injury (TBI) is a serious medical condition that often leads to significant morbidity and mortality. Decompressive craniectomy (DC) is now widely recognized as a primary or secondary treatment option for managing intracranial pressure (ICP) in patients with severe TBI. However, there is a lack of clarity in reviews regarding the impact of DC on TBI outcomes.

Objectives:

The aim of this study is to evaluate the effectiveness of DC in terms of overall mortality and long-term prognosis among patients with TBI.

Materials and Methods:

We conducted a systematic search of four common databases to include all parallel-arm randomized controlled trials (RCTs). We selected studies that reported outcomes for TBI cases, with DC as a treatment option. The outcomes examined included reduction in mortality, ICP levels, and the proportion of patients with a Glasgow Outcome Scale score >4.

Results:

Our review finally included eight RCTs [n= 1458, with 749 and 709 patients in the DC and control groups, respectively]. The weighted mean difference for ICP was estimated at -4.01 (95% Confidence interval [CI]: -5.31–-2.71), indicating a statistically significant reduction in ICP levels in the DC group compared to the control group. The pooled risk ratio was 0.67 (95% CI: 0.51–0.89), suggesting a statistically significant 31% decrease in mortality levels in the DC group. Subgroup and sensitivity analyzes were also conducted to address heterogeneity.

Discussion and Conclusion:

In conclusion, based on our meta-analysis, we find that DC can be considered a crucial surgical intervention for reducing mortality among patients with TBI when compared to control groups.
An Unusual Presentation of an Ectopic Mandibular Third Molar in the Condylar Region: A Case Report and Review of Literature
Authors: Patel Hiren , Pandya Haren , Dewan Hitesh , Bhavsar Bijal , Shah Urvi , Makwana Parth
Published: December 2023

Rationale:

Ectopic teeth arise from developmental abnormalities, pathological conditions or iatrogenic factors. They can be supernumerary, deciduous or permanent and cause dental and facial pain, swelling and infection. Limited cases reveal limited knowledge about causes, symptoms, treatment options and surgical procedures. A thorough evaluation, including radiographic imaging and clinical examination, aids diagnosis and treatment planning.

Patient Concern:

A 54-year-old female patient complains of tooth mobility in the upper right back tooth region for one month and occasional pain in the right pre-auricular region.

Diagnosis:

Chronic generalised periodontitis with an impacted tooth in the right condylar region.

Intervention:

Extraction of Grade III mobile 17 and conservative treatment for ectopic molar in the condylar region.

Outcome:

The patient is on regular follow-up with no similar complaints.

Take-Away Lesson:

A personalised approach is crucial in managing ectopic mandibular third molars and should take into account the patient’s symptoms, preferences and potential complications. Successful treatment requires informed decision-making and thorough evaluation.
Microvascularized Fibular Bone Grafting for the Treatment of Mandibular Expansive Osseous Dysplasia - A Case Report
Authors: Barbeiro Camila de Oliveira , Verzola Mario Henrique Arruda , Barbeiro Roberto Henrique , Tachibana Wilson Tadao , León Jorge Esquiche , Bufalino Andreia
Published: December 2023

Rationale:

Osseous dysplasia (OD) is a benign fibro-osseous lesion classified as periapical, focal or florid with some rare cases being diagnosed as expansive OD.

Patient Concerns:

A 43-year-old female presented with gross mandible expansion and tooth displacement.

Diagnosis:

Imaging scans revealed an expansive lesion in the anterior mandible, with varying opacity in the central region, and other smaller lesions in the region of teeth #37 and #47, consistent with expansive OD.

Treatment:

Surgical resection followed by immediate reconstruction of the mandibular defect using a microvascularized fibular graft.

Outcomes:

The patient had a 4-year follow-up, with adequate mandibular bone continuity, mastication, swallowing, and speaking ability reestablished.

Take-away Lessons:

Immediate reconstruction after large surgical resection is required as tissues retract over time, hampering late reconstructions. Microvascularized fibular graft aims at adequate and functional rehabilitation with osseointegrated implants and long-term follow-up is needed as florid OD may evolve into expansive OD.

Published: December 2023

Objective:

This study aims at detecting KIBRA promoter methylation and association with clinic-pathological manifestations in renal cancer.

Materials and Methods:

In this study, we have studied the KIBRA promoter methylation in twenty cases of renal cell cancer and compared them to their stage, grade, and histopathology.

Result:

We have found that significant amount of KIBRA promoter methylation is present in high grade tumors irrespective of the stage. 5 out of 6 grade III tumors and all 6 grade IV tumors were positive for significant KIBRA promoter methylation as compared to 1 out of 5 grade I tumor.

Conclusion:

DNA methylation alterations participate in renal carcinogenesis which significantly correlated with the clinicopathological diversity of clear cell renal cell carcinomas and can be considered as potential targets for therapy.
A Case of Tracheal Rent Caused by Blunt Trauma to the Anterior Neck
Authors: Michael Binoy , Goje Harindra Kumar
Published: December 2023

Tracheobronchial injury (TBI) is an uncommon and potentially life-threatening injury, but very little data are available to guide the management of the same. TBI due to blunt or penetrating trauma is rare and most individuals succumb to asphyxiation from airway obstruction or tension pneumothorax even before reaching the hospital. We present the case of a 25-year-old male who was brought to the emergency room with a history of blunt trauma to the anterior neck, leading to swelling and pain at the site of injury associated with progressive loss of speech and worsening dyspnoea. Gradually, increasing neck swelling along with progressive loss of phonation and worsening dyspnoea forced us to consider a tracheal injury in this patient. We discuss the sequence of events that lead to the occurrence of tracheal injury, and the prompt diagnosis and efficient management which are the cornerstones in saving the patient’s life.
Triggers in controlled ovarian hyperstimulation
Authors: Devi Madampath Gouri
Published: December 2023

Controlled ovarian hyperstimulation (COH) is a crucial component of assisted reproductive technologies like intrauterine insemination (IUI) and in vitro fertilization (IVF). Triggers in COH play a pivotal role in maturation of the follicles in their final stages and optimizing the timing of egg retrieval, which is very important for the collection of maximum eggs and for a good success rate. Human chorionic gonadotropin (hCG) is used as a standard method for the final follicular maturation and ovulation. HCG has the similar effect as luteinizing hormone (LH) with a half-life of 5–7 days. Now a days, gonadotropin-releasing hormone agonist (GnRH-a) trigger has been used with the target to reduce OHSS for the induction of final follicular maturation and ovulation. Based on the results of various studies, using the GnRH-a trigger leads to defects in the luteal phase resulting in reduced implantation and clinical pregnancy rates and also increasing abortion rates in fresh embryo transfer cycles compared to the routine IVF cycle with hCG triggering. In this review, we examined the benefits, problems and also ways to reform various triggers used for ovulation.

Published: December 2023

Introduction:

Fear and anxiety toward dentists, syringes, and white coats are significant issues affecting the treatment of pediatric patients. According to D.C.I guidelines for the COVID-19 pandemic, it was made mandatory to wear personal protective equipment (PPE) for dental professionals, adding one more cause of fear and anxiety, which made it more challenging to treat pediatric patients. Friendly dentist attire can make a positive impact on a patient’s behavior.

Aim:

This study aimed to assessment of choice for dentist’s attire and their effect on anxiety of 5–12-year-old children.

Materials and Methods:

The present study was conducted in the Department of Pediatric and Preventive Dentistry, IDS, Bareilly. To assess the choice of dentist’s attire, a questionnaire consisting of 15 closed and open-ended questions was formulated and was asked to be filled by 182 patients with the help of their parents, who reported in our operatory. To assess the pre- and postanxiety levels among patients, vitals (blood pressure and pulse rate) and facial image scores were recorded. Data obtained were subjected to statistical analysis.

Results:

Majority of the children, i.e., 58.8%, showed preference for modified PPE with cartoon characters. Facial Image Scale: Score 2, i.e., sad face, was scored by 7% of children at baseline, and was reduced to only 1% after attire selection. Significant differences were seen in physiological parameters.

Conclusion:

Clinician’s attire and appearance play a major role in behavior modification of anxious children. Modified PPE with cartoon characters was the attire of choice for the majority of children.

Orthodontic treatment has been a boon for many patients who wish to change their esthetic appearance that goes concomitantly with their psychological well-being. This treatment modality has changed strenuous appliance design to simple but excellent result delivering appliances. The duration of orthodontic treatment has always been a major challenge in relation to the patient’s compliance, so the appliance which an orthodontist delivers to a patient should always be efficient and also produce good results in a short period of time. An 18-year-old female patient came to the department of orthodontics with a chief complaint for forwardly placed upper front teeth; upon examination, the patient showed Class II skeletal and dental relation with increased overjet and overbite with horizontal growth pattern. The patient was given Tip-Edge appliance since it can reduce the large overjet in a short duration, and treatment was completed within 13 months. Tip-Edge appliance delivers faster results when compared with other appliances, which helps a lot in the patient’s compliance and satisfaction.
