Published: April 2024

In order to promote the universal application of bamboo materials as well as to provide reference for the study of the performance of bamboo, four kinds of flame retardants (boric acid (BA), borax (BX), ammonium polyphosphate (APP), disodium octaborate tetrahydrate (DOT)), two kinds of ultraviolet light absorbers (UV-531, nano TiO2) were added into waterborne polyurethane (WPU) to synthesize 5 kinds of modified coatings and coated on the surface of bamboo to make test materials. The flame-retardant analysis of the coated samples comprehensively explored the changes in flame retardancy of the test material after treatment. And the anti-aging test was carried out to investigate the color difference and adhesion change of the coating sample. The results show that the optimum flame retardant and anti-aging coating composition was obtained as 20% solid content of WPU, 8g coating amount of modifier, with the mass ratio of BA/BX/APP /DOT/water being 75:75:7:42:600, and the amount of UV-531 added being 1%.

Podocituria y preeclampsia
Authors: Reyes Osvaldo
Published: April 2024

El podocito es una célula altamente diferenciada localizada en la membrana basal del glomérulo. Entre sus múltiples funciones está garantizar la integridad y funcionalidad de la principal unidad de filtración del riñón, pero carece de la capacidad de dividirse bajo condiciones normales y en situaciones de estrés presenta el riesgo de separarse de la membrana basal, lo que conlleva la posibilidad de desarrollar proteinuria como primer paso de un daño renal que puede llegar a ser permanente. Una de estas situaciones de estrés es el embarazo y, en particular, los trastornos hipertensivos gestacionales, lo que coloca al podocito en la peculiar posición de poderse utilizar como prueba diagnóstica o como marcador de pronóstico renal a largo plazo. En esta revisión veremos el papel del podocito en estos escenarios.
A Case of Hypertensive Retinopathy With Papilledema Manifested as Blurry Vision, Headache, and Dizziness in a Patient With a Recent Diagnosis of Peritoneal Tuberculosis
Authors: Mohamed Siraj Hashim , Faisal AbuSamrah Bakr
Published: April 2024

Hypertension poses significant risks to various organ systems, including the eyes, leading to target-organ damage known as hypertensive retinopathy (HR). This case report explores the case of a 60-year-old male presenting with blurred vision, headache, and dizziness, ultimately diagnosed with grade IV hypertensive retinopathy. The patient had a complex medical history including hypertension, dyslipidemia, ischemic heart disease, diabetes mellitus, and peritoneal tuberculosis, with recent initiation of anti-tuberculosis therapy. Differential diagnoses encompassed various ocular and systemic conditions, highlighting the importance of a thorough evaluation. Fundoscopic examination revealed bilateral papilledema and flame hemorrhages consistent with hypertensive retinopathy. Management involved meticulous blood pressure control and ophthalmological referral. Collaboration between healthcare providers facilitated comprehensive care. Following treatment, the patient's blood pressure improved, necessitating adjustments in antihypertensive medications. This case underscores the critical role of recognizing ocular manifestations in hypertensive patients and the need for interdisciplinary management to mitigate systemic morbidity and mortality. Ongoing research is crucial to enhance diagnostic and therapeutic strategies for hypertensive retinopathy, ensuring optimal patient outcomes.

Revealing the Variation Mechanism of ON 231 via the Two-component Shock-in-jet Model
Authors: Wang Chi-Zhuo , Jiang Yun-Guo
Published: April 2024

The variation mechanism of blazars is a long-standing unresolved problem. In this work, we present a scenario to explain diverse variation phenomena for ON 231, where the jet emissions are composed of the flaring and the less variable components (most probably from the post-flaring blobs), and the variation is dominated by shock-in-jet instead of the Doppler effect. We perform correlation analysis for the multiwavelength light curves and find no significant correlations. For the optical band, ON 231 exhibits a harder when brighter (HWB) trend, and the trend seems to shift at different periods. Correspondingly, the correlation between the degree of polarization and flux exhibits a V-shaped behavior, and a similar translation relation during different periods is also found. These phenomena could be understood via the superposition of the flaring component and slowly varying background component. We also find that the slopes of the HWB trend become smaller at higher flux levels, which indicates the energy-dependent acceleration processes of the radiative particles. For the X-ray band, we discover a trend transition from HWB to softer when brighter (SWB) to HWB. We consider that the X-ray emission is composed of both the synchrotron tail and the synchrotron self-Compton components, which could be described by two log-parabolic functions. By varying the peak frequency, we reproduce the observed trend transition in a quantitative manner. For the γ-ray band, we find the SWB trend, which could be explained naturally if a very-high-energy γ-ray background component exists. Our study elucidates the variation mechanism of intermediate synchrotron-peaked BL Lac objects.
General-relativistic Radiation Transport Scheme in Gmunu. II. Implementation of Novel Microphysical Library for Neutrino Radiation—Weakhub
Authors: Ng Harry Ho-Yin , Cheong 張 Patrick Chi-Kit 志杰 , Lam Alan Tsz-Lok , Li Tjonnie Guang Feng
Published: April 2024

We introduce Weakhub, a novel neutrino microphysics library that provides opacities and kernels beyond conventional interactions used in the literature. This library includes neutrino–matter, neutrino–neutrino interactions and plasma process, along with corresponding weak and strong corrections. A full kinematics approach is adopted for the calculations of β-processes, incorporating various weak corrections and medium modifications due to the nuclear equation of state. Calculations of plasma processes, electron neutrino–antineutrino annihilation, and nuclear de-excitation are also included. We also present the detailed derivations of weak interactions and the coupling to the two-moment based general-relativistic multigroup radiation transport in the general-relativistic multigrid numerical (Gmunu) code. We compare the neutrino opacity spectra for all interactions and estimate their contributions at hydrodynamical points in core-collapse supernovae and binary neutron star (BNS) postmerger remnants, and predict the effects of improved opacities in comparison to conventional ones for a BNS postmerger at a specific hydrodynamical point. We test the implementation of the conventional set of interactions by comparing it to an open-source neutrino library NuLib in a core-collapse supernova simulation. We demonstrate good agreement with discrepancies of less than ∼10% in luminosity for all neutrino species, while also highlighting the reasons contributing to the differences. To compare the advanced interactions to the conventional set in core-collapse supernova modeling, we perform simulations to analyze their impacts on neutrino signatures, hydrodynamical behaviors, and shock dynamics, showing significant deviations.
Insect floral visitors of thermo-Mediterranean shrubland maquis (Ajaccio, Corsica, France)
Authors: Maestracci Pierre-Yves , Plume Laurent , Gibernau Marc
Published: April 2024

The Mediterranean Region represents a biodiversity hotspot with a high rate of endemism. In its western part, Corsica Island is notable in terms of biodiversity due to its large surface and its large range of habitats from seaside to alpine biotopes. Amongst diverse groups, insects, notably the main orders of pollinators composed of Coleoptera, Hymenoptera, Diptera and Lepidoptera, represent a good part of the insular richness.

Our sampling effort focused on the insects from these four orders visiting flowers in a characteristic thermo-Mediterranean vegetation. Our database is an insight into the Corsican floral visitor biodiversity from three sites separated by a few kilometres in the region of Ajaccio during 13 months over two successive years. In total, 4012 specimens were sampled and 252 species or morpho-species identified from 133 genera and 47 families. Beetles were by far the most abundant order representing about 54% of the sampled specimens. The most diverse order was the Hymenoptera representing 39% of the species. Our continuous survey showed that these orders are temporally dynamic both between years and between seasons in terms of abundance and diversity.
Bibliometric analysis of publications trends in Indonesian research institutions: A comparison of pre-integration (2015–2021) and post-integration (2022–2023) periods
Authors: Handoyo Setiowiji , Prastiti Poppy Indah Dwi , Stiaji Iwan Ridwan
Published: April 2024

Background: Institutional transformation – integrating many disparate research insti-tutes into the National Research and Innovation Agency (BRIN, for Badan Riset dan Inovasi Nasional) – was the most significant reform in the history of institutional gov-ernance in Indonesia. This integration policy aims to enable the state to strengthen the national research and innovation ecosystem and improve the performance of research institutions, one indicator of which is their output of publications reporting the results of research.

Objectives: To compare the published output of research institutes before and after the integration of research institutions into BRIN.

Methods: Relevant data retrieved through Scopus on 24 December 2023 and span-ning the period between 2015 and 2023 were analysed using Microsoft Excel, and col-laboration networks of authors and of countries were constructed using VOSviewer and examined for co-authors in different countries collaborating with first authors in Indonesia.

Results: The number of publications increased annually over the period 2015–2023. However, the annual rate of growth after (2021–2023) the integration of research institutions was higher (36%) than that before (2015–2021) the integration (30%). Conference papers (51%) dominated the pre-integration era, whereas articles (57%) dominated the post-integration era, and the number of reputable journals in which the research was published was greater after the integration.

Conclusions: The period after the integration of research institutions saw enhanced research output in terms of the number of research publications, annual rate of growth in that number, and the number of reputable journals in which the publica-tions appeared.
Impact of hail-netting on Vitis vinifera L. canopy microclimate, leaf gas exchange, fruit quality, and yield in a semi-arid environment
Authors: Ruland K. , Montague Thayne , Helwi Pierre
Published: April 2024

Hail events have the potential to destroy grapevine shoots, reduce yield, and inflict economic loss upon growers. As a result, many grape growers have adopted the use of hail-netting to mitigate potential vine damage. Although hail-netting has been observed to prevent hail damage, Texas High Plains grape growers have expressed concerns regarding effects hail-netting may have on vine canopy microclimate, grapevine health, fruit maturity, fruit quality and yield. Therefore, over three growing seasons (2018 – 2020), field-grown vines (Vitis vinifera L. ‘Malbec’ and ‘Pinot gris’) were exposed to hail-netting, or grown without hail-netting. Each growing season canopy microclimate, leaf gas exchange, fruit maturity, yield parameters, and vegetative growth were monitored. Netting reduced canopy air and leaf temperature and decreased canopy vapour pressure deficit. By modifying light infiltration and leaf temperature, hail-netting altered leaf gas exchange. In addition, gas exchange differences were found between cultivars. Although fruit pH and total acidity were not different at harvest, fruit maturity measurements revealed total soluble solid development was influenced by netting and cultivar. Vine cluster numbers were greater for vines without netting and yield parameters were generally lower for ‘Malbec’ vines. Pruning weights indicate decreased vegetative growth for hail-netting and ‘Pinot gris’ vines. Results suggest grape-growers' use of hail-netting may allow growers to achieve fruit production goals. However, when using hail-netting, growers should consider possible management modifications due to changes in vine physiology, fruit maturation, and harvest schedules.

Purpose:

To analyze referral rates, patient demographics, referral indications, and the impact of socioeconomic factors on ocular health from the University of California Irvine (UCI) Eye Mobile for Children, particularly during the coronavirus disease 2019 (COVID-19) pandemic.

Methods:

A retrospective chart review was performed on de-identified records of children examined on the UCI Eye Mobile. GraphPad Prism 10.0.0 and Python software were used for statistical analyses.

Results:

In the academic years from 2018 to 2022, 3,619 children received comprehensive eye examinations on the UCI Eye Mobile. Among them, 76 were referred to a pediatric ophthalmologist. The majority of these children were Hispanic (72.6%, 54 of 74), followed by Asian (10.9%, 8 of 74). A significant proportion (82.9%, 63 of 76) attended school districts with median incomes below that of Orange County. Statistically significant differences were found in age (
P
= .001; pre-COVID: 3.98 ± 1.08 years vs COVID: 5.75 ± 2.92 years) and gender (
P
= .023; pre-COVID female: 31 of 41 vs COVID female: 15 of 32) between the pre-COVID and COVID years. Additionally, there were significant differences in the proportion of children with hyperopia with astigmatism between the pre-COVID and COVID years (
P
= .044; pre-COVID: 23 of 40 vs COVID: 12 of 35). The most common indications for ophthalmologist referrals were for strabismus evaluation/treatment (28.9%, 22 of 76), followed by abnormal cup-to-disc ratio (21.1%, 16 of 76).

Conclusions:

The study highlights the pivotal role of the UCI Eye Mobile for children in identifying ocular conditions needing referrals to subspecialty care. The majority of children needing these referrals attended schools in lower economic communities. Additionally, the COVID-19 pandemic appears to have influenced the demographic and clinical characteristics.

Génétique « textuelle » et adaptations transmédiatiques
Authors: Boillat Alain
Published: April 2024

La réflexion menée dans cette étude se propose, tout en faisant un état des lieux commenté des recherches en critique génétique portant sur des adaptations (en particulier cinématographiques), de déployer et d’examiner les termes du paradoxe qui réside dans le fait que, bien que l’adaptation puisse être considérée, comme l’auteur le démontre ici, comme un objet intrinsèquement génétique appelant une démarche comparative, elle n’a été à ce jour que très peu discutée à l’aune de la méthodologie de cette discipline. Ce constat tient notamment à une hiérarchie des valeurs qui tend à instaurer un rapport d’inféodation du médium-cible à une œuvre originale bénéficiant d’une légitimation culturelle supérieure. Afin d’« adapter » la génétique à cet objet qui, dans différents médias, implique une pluri-stratification sémiotique, l’auteur propose de ne plus concevoir cette approche comme strictement « textuelle », mais de l’ouvrir à d’autres types de phénomènes, lesquels, à l’instar de l’incarnation à l’écran d’un personnage romanesque par un interprète porteur de sa persona propre, n’en agissent pas moins sur certains textes (notamment scénaristiques) qui témoignent de la genèse de l’œuvre.
Les réécritures des Mystères de Paris d’Eugène Sue

Le présent article est consacré aux réécritures du roman-feuilleton Les Mystères de Paris d’Eugène Sue au passage de la presse (1ère édition) au livre (2ᵉ et 3ᵉ éditions). Après avoir présenté la genèse de l’œuvre, l’autrice met en relation les variations textuelles avec les supports de publication des différentes versions. Ces supports, caractérisés par leur matérialité et leur signification culturelle, sont envisagés comme des médias. L’adaptation transmédiale de la presse au livre permet d’expliquer certaines variations de l’œuvre. Dans une analyse ancrée en linguistique textuelle, trois phénomènes narratifs et textuels qui témoignent du changement de support comme facteur de réécriture, sont pris en considération : le renforcement de la clôture du texte, les ajustements textuels lors de la disparition des coupes matérielles inhérentes à la publication dans la presse, et l’estompement de la présence de l’instance de narration.
Le scénario de bande dessinée, aval du roman et amont de l’album
Authors: Boillat Alain
Published: April 2024

L’article examine trois états scénaristiques de la bande dessinée en deux tomes Moby Dick parue chez Delcourt en 2005, adaptation du roman homonyme de l’écrivain Herman Melville que les auteurs ont conçue comme une transposition dans un autre genre, la science-fiction. L’étude porte spécifiquement sur le stade de l’écriture, souvent négligé dans les recherches sur ce médium qui tendent à privilégier la conception visuelle. L’auteur de l’article discute comment la matière du roman est retravaillée au cours de la genèse scripturale et du transfert vers un autre genre qui affecte le monde représenté, et comment celle-ci programme la genèse graphique – laquelle s’avère très peu contrainte sur le plan de la composition tabulaire des planches –, dans un cas de figure où les deux auteurs ont travaillé de manière successive et quasi autonome. Ces modalités de la collaboration entre scénariste et dessinateur sont ensuite contextualisées par rapport à la diversité des pratiques existant dans ce médium, illustrée succinctement avec la genèse d’une autre œuvre, 1984, adaptation par Xavier Coste du roman de George Orwell parue en 2021 aux éditions Sarbacane, pensée comme un roman graphique et dont l’auteur a simultanément assumé les tâches de scénariste et de dessinateur.
Deepening Identity Divides in Post-Brexit Britain: The Home Office, Rhetoric and Authoritarianism
Authors: White Jordan
Published: April 2024

This paper analyses the rhetoric of Home Secretaries Priti Patel (2019-2022) and Suella Braverman (2022-), and builds on Judi Atkins’ study of former Home Secretary and Prime Minister Theresa May by examining the epideictic and deliberative style employed in their speeches to the Conservative Party Conferences of 2020 and 2022 respectively. A Rhetorical Political Analysis establishes a common trend in the rhetorical strategies used by these three speakers. By outlining the various appeals to pathos and logos, such as patriotic sentiment or disgust reflexes, this study begins to form a clearer image of the ingroups and outgroups developed through discourse. The antithetical nature of these appeals suggests an expanding outgroup—Asylum seekers, Human Rights lawyers and eco-protestors are targeted—as the ingroup seemingly shrinks beyond Leave voters to a smaller subset of “identity conservatives” (Sobolewska & Ford) or “Somewheres” (Goodhart). A comparative linguistic analysis of documents related to recent anti-immigration and anti-protest policies (the Public Order Bill and Rwanda Plan) highlights connections between the language used by the Home Secretaries and policy i.e., the connections between rhetoric and government. This analysis does not argue causation, but indicates correlation between the two, and serves to refute suggestions that rhetoric is “empty” and performative. Finally, public opinion is studied to ascertain whether the orators’ claims about the electorate, and their proposed policies, are supported. Reference to opinion polls show that certain policies (such as harsher punishments for eco-protestors granted under the Public Order Bill) appear to be supported by a significant minority of the public while opinion is divided on others (the Rwanda Asylum Plan). In most cases these policies do seem to appeal to an important subset of Conservative voters, suggesting that both rhetoric and policies are tailored to a shrinking ingroup of identity conservatives or “Somewheres”.
Divided but linked by faith: Brexit and UK Muslims’ attitudes towards Europe
Authors: Touihri-Mebarek Donia
Published: April 2024

While issues of race and diversity have significantly dominated the rhetoric of Brexit Leavers and have shaped Britons’ attitudes towards membership of the European Union (EU), ethnic and religious minority voters’ attitudes towards Brexit have received little investigation. This article aims to fill this research gap by focusing on Muslims. It examines what differentiates Muslim Remainers from Muslim Leavers by focusing on their motivations to vote for or against Brexit. Despite being the religious group that was the most supportive of EU membership, the EU referendum has also created identity divisions amongst Muslims and has shed light on their ambivalent attitudes towards Europe and the benefits of EU membership. Several cumulative and cross-cutting factors have polarised this group regarding EU membership, such as their different perceptions of Europe and European identity, as well as issues pertaining to discrimination and Islamophobia, immigration and the economy.We argue that, beyond the divisions, Muslims’ attitudes towards Brexit were strongly correlated with the concept of ‘linked fate’, with the religious paradigm being an important predictor of Muslims’ voting behaviour.

Pesquisa descritiva, foi realizada mediante levantamento, com 267 profissionais da área de controladoria de empresas que atuam no Brasil, e abordagem quantitativa dos dados (MEE). Os resultados apontam que a participação orçamentária influencia positivamente o compartilhamento de informações, e esta variável exerce influência positiva no envolvimento no trabalho, nas atitudes gerenciais e no desempenho gerencial. O desempenho gerencial também está associado com o envolvimento no trabalho e atitudes dos gestores em relação ao orçamento. Não foram confirmados os efeitos do envolvimento no trabalho nas atitudes gerenciais em relação ao orçamento. Os efeitos mediadores do compartilhamento de informações verticais foram constatados na relação entre participação orçamentária, atitudes gerenciais e desempenho. Estes resultados revelam que em condições de maior nível de compartilhamento de informações, os controllers participantes do estudo apresentam maior influência e envolvimento nos processos orçamentários, maior comprometimento, envolvimento no trabalho e atitudes gerenciais proativas em relação ao orçamento, o que reflete positivamente no desempenho gerencial em atividades orçamentárias. Estes achados contribuem para a literatura ao adicionarem novas evidências dos efeitos cognitivos mediadores do compartilhamento de informação vertical na relação entre participação orçamentária, atitudes gerenciais em relação ao orçamento e o desempenho gerencial.
impacto do Ciclo de Vida na relação entre Governança Corporativa e Custo de Capital das Organizações
Authors: Ames Alice Carolina , Hein Nelson
Published: April 2024

Este estudo analisa a influência do ciclo de vida na relação entre a governança corporativa e o custo de capital. Para tanto, realizou-se uma pesquisa descritiva, archival e quantitativa. A população do estudo compreendeu todas as empresas brasileiras listadas na Brasil, Bolsa, Balcão [B]3, do período de 2015 a 2018. Os resultados da pesquisa apontaram que há uma relação entre o estágio do ciclo de vida da organização e o custo de capital implícito. Desta forma, empresas que estão em seus estágios iniciais investem mais em mecanismos de governança corporativa, e por estarem buscando um lugar no mercado, incorrem em maiores gastos e o custo de capital é mais elevado. Entretanto, foi evidenciado que o investimento em governança corporativa tende a ser atenuado no estágio de maturidade, esse fator pode estar atrelado a justificativa de que, por as empresas estarem mais equilibradas financeiramente e quanto as condutas internas, tenha-se um menor investimento adicional em governança corporativa. Por outro lado, questões do cenário econômico também podem afetar o custo de capital das empresas, dadas as oscilações do país analisado. Estas evidências contribuem para a literatura que se refere a governança corporativa e ao entendimento da distinção entre níveis de governança corporativa dependendo do estágio do ciclo de vida. Ademais, apenas no estágio de introdução que foi evidenciada uma relação positiva com o custo de capital implícito, ou seja, nesse estágio as organizações tendem a potencializar investimentos em governança e exige um aumento no custo do capital. Assim, alinhado com estudos anteriores, foi verificado que  os regimes de governança podem mudar com o decorrer do tempo.

A better understanding of the entrepreneur’s behavior should consider multiple theoretical perspectives. In this respect, studies capable of integrate different perspectives under a holistic framework are welcome. Gathering constructs under three perspectives, entrepreneurial-based view, resource-based view and market-based view, this article presents a holistic view about how the entrepreneur background influences the firm' strategy in a traditional industry. This article adopts a holistic perspective of the entrepreneurship investigating the importance of the entrepreneurs' background in their strategic decisions, showing important insights. Through the qualitative approach there were performed eleven comparative case studies with agricultural entrepreneurs of the artisanal cachaça industry in a mining region, which production started in the XVI century and is intimately related to the historical origin of Brazil. In the majority, entrepreneurs have access to key production and market resources through family ties. This situation directly influences the product value attributes, the consumer segments focused, and the size of product lines. There is also a relation between the entrepreneurs' motivation and segmentation strategy and between their formal education and cognitive style. This article should guide the elaboration of entrepreneurial training programs, whereas the firm's strategy can be designed considering the entrepreneur background.

The aim of this study is to investigate the macroeconomic component Investment Opportunities influence, extracted by the multivariate PCA method, on firms' financial performance. The analysis was conducted in two stages: i) Principal Component Analysis (PCA) to circumvent the multicollinearity problem and identification of the Investment Opportunities variable; and ii) Application of the Systemic Generalized Method of Moments (GMM) both to analyze the relationship between Investment Opportunities and firms' financial performance (measured by current and future ROE), and to correct for data endogeneity. The sample comprises 160 non-financial companies, with quarterly data from 2010 to 2020. We use the PCA method exploratively to identify the first principal component as the predictor variable in the econometric model. It was extracted from macroeconomic variables, which include GDP variation and activity indexes, confidence, and agents’ expectations in Brazilian economy. Finally, we applied the GMM panel data modeling.  The results showed that the Investment Opportunities variable has a positive and significant effect on companies’ financial performance, with persistent effects in future quarters. Furthermore, we demonstrate that financial performance is highly responsive to these opportunities with significant results in all estimated models. This study makes a practical and theoretical contribution by demonstrating, through multivariate analysis, how economic conditions are important exogenous drivers of firm performance and competitive advantage.

O objetivo do estudo consiste em investigar a influência da adoção das IFRS e da qualidade da evidenciação no desempenho de mercado de empresas brasileiras. Para tanto, realizou-se a utilização de métodos estatísticos como correlação e regressão linear múltipla (OLS). Os dados referem-se ao período de 2001-2007 (pré-IFRS) e 2010-2017 (pós-IFRS). A amostra compreendeu 108 empresas que apresentaram informações para todas as variáveis analisadas. Os resultados do estudo sugerem que o desempenho de mercado é influenciado pelo ROE (negativamente) e pelo ROA (positivamente), mas a adoção das IFRS elimina esse efeito. Além disso, ficou evidente que o mercado consegue antecipar as informações do desempenho da empresa (ROE), principalmente no período pós adoção, o que pode explicar a falta de relevância da divulgação do ROE para o mercado. Os achados revelam que as notas explicativas e relatório de administração passam a ser relevantes para o mercado após a adoção das IFRS. Como contribuição os resultados deste estudo podem ser úteis para reflexões quanto aos modelos de decisão utilizados por investidores, para que órgãos reguladores reflitam sobre as necessidades informacionais dos usuários da informação contábil e sobre o timing da divulgação de informações.

Background: overcrowding and long waiting times are major problems in Emergency Departments (EDs). Fast-Track (FT) is a process developed to more effectively manage patients admitted to EDs with non-urgent conditions. The aim of the study was to evaluate the impact of the FT method regarding access in an ED. Materials and Methods: pre-post implementation study of the FT method. All patients attending the emergency department of the ASL of Barletta presenting minor emergencies with problems in the obstetric/gynaecological, ophthalmological, paediatric, otorhinolaryngological and orthopaedic areas were included. Results: of the 38,024 services performed in the ED, 1606 (4.22 %) were FT accesses. Analysing the data from the period May 2017 (pre) and calculating in minutes the waiting time from triage to discharge is 55 minutes; instead in the period May 2022 (post) it is 20 minutes. Conclusions: the FT method seems to be a useful and safe strategy to improve the management of patients admitted to emergency rooms with minor disorders.
HIV/AIDS in South Africa: A case of failed responses because of stigmatization, discrimination and morality, 1983-1994
Authors: Grundlingh Louis
Published: April 2024

Die artikel ondersoek die aard van stigmatisering, diskriminasie en moraliteit in die SuidAfrikaanse samelewing nadat MIV/VIGS ook hier sy verskyning gemaak het. Aanvanklik het godsdienstige fundamentaliste homoseksueles daarvan beskuldig dat hulle deur die virus besmet is omdat hulle homoseksueel is. Hierdie sienings is aangevul deur die middelklas waardes van die tyd wat epidemies met sedeloosheid vereenselwig het. Die regering sou feitlik niks doen om voorkoming van MIV in die homoseksuele gemeenskap te bekamp nie. Deur die "ander' (in hierdie geval die MIVA/lGS-lyer) te stigmatiseer en ook teen die persoon te diskrimineer, kon heelwat Suid-Afrikaners die lyers en die hele vraagstuk rondom MIVA/IGS ignoreer. 'n Nuwe kategorie van onderskeiding is so geskep: "ons" (die gesonde heteroseksuele gemeenskap) en "hulle" (die besmette homoseksuele gemeenskap). Stigmatisering en diskriminasie teenoor swartmense, wat alreeds lank in die SuidAfrikaanse konteks bestaan het, het teen 1987 'n nuwe dimensie bygekry toe die eerste swart heteroseksuele persoon as MIV+ identifiseer is. Die persepsie het nou toegeneem dat alle swartes vir die epidemie verantwoordelik gehou behoort te word. Hierdie rassistiese siening het baie daartoe bygedra dat enige anti-MIV/VIGS program van die regering, hoe goed bedoel ookal, as gevolg van 'n gebrek aan legitimiteit in die swaH gemeenskappe verwerp is. Gevolglik is niks effektiefin die 1980s gedoen nie. Dit wil voorkom of die hoofargument wel onderskryf kan word: dat stigmatisering van en diskriminasie teenoor gemarginaliseerde groepe, rassisme en homofobie sowel as 'n konserwatiewe moraliteit wat 'n sterk invloed uitgeoefen het, daartoe gelei het dat 'n gulde geleentheid om MIV/VIGS te bekamp, verlore gegaan het.

Authors: Amer Ahmed M , Mohamed Kareeman G , Shibel Passant A , Fayiad Hussein E
Published: April 2024

Background

Pleural effusion may be malignant or nonmalignant, Cytology has been used in malignant pleural effusion (MPE) diagnosis due to its high specificity. Its sensitivity is about 0.6. Cancer ratio (CR) and carcinoembryonic antigen (CEA) may be used in MPE diagnosis.

Aim

Evaluate the role of CR and CEA as diagnostic markers of MPE and their role in differentiating different types of MPE.

Patients and methods

This cross-sectional study included 70 patients with pleural effusion admitted to Chest Department, Kasr Alainy Faculty of Medicine, Cairo University. Thirty-five patients had benign pleural effusions and 35 patients had MPE. Pleural fluid sample obtained from each patient for ADA, CEA, and serum LDH. CR and pleural fluid CEA were compared between patients with MPE and those with benign effusion.

Results

CR was statistically significantly higher in the malignant group (mean 23.66 ± 7.75) compared with benign group (mean 14.47 ± 11.42) with P value less than 0.001. CR cut-off value was 19.79, the sensitivity and specificity were 74.3 and 82.9%, respectively. Pleural fluid CEA had higher levels in malignant group (mean 104.78 ± 262.7) compared with benign group (mean 2.08 ± 2.49) with P value less than 0.001. The cut-off value of CEA was 3.4 U/l with sensitivity 74.3% and specificity 94.3%. Pleural fluid CEA was significantly higher in metastatic adenocarcinoma (mean 154.58 ± 314.53) compared with other types of malignancy (mean 9.34 ± 17.98) with P value less than 0.001.

Conclusion

CR and CEA could be used together as simple screening tests in cytology negative MPE with high specificity and sensitivity. CEA was significantly higher in metastatic adenocarcinoma compared with other types of malignancy and could be used to differentiate different types of MPE.

Published: April 2024

Background:

Early assessment of severity of acute pancreatitis is very essential for the selection of patients who will require intensive care to prevent local complications and organ dysfunction. Several scoring systems have been developed, but these require large number of clinical and biochemical parameters, making them overly complicated and cumbersome. There is a need to develop simple clinical investigations which would help in assessing the severity of acute pancreatitis. Hence, the present study is undertaken to evaluate the role of inflammatory biomarkers (interleukin-6 [IL-6], IL-8, and tumor necrosis factor-alpha [TNF-α]) in the assessment of severity in acute pancreatitis.

Materials and Methods:

This cross-sectional study was conducted at a tertiary care teaching hospital in North India and enrolled 50 patients with acute pancreatitis. Serum levels of IL-6, IL-8, and TNF-α were measured within 24 h of admission.

Results:

The levels of IL-6, IL-8, and TNF-α were found to be significantly higher in patients with severe pancreatitis as compared to mild disease. With a cutoff level of >46.379 pg/ml, IL-6 had a sensitivity of 96.15%, specificity of 95.83%, and diagnostic accuracy of 96% for predicting progression to severe acute pancreatitis. Similarly, IL-8 >39.54 pg/mL had a sensitivity of 92.31%, specificity of 91.67%, and diagnostic accuracy of 92%. TNF-α >11.80 pg/mL had a sensitivity of 53.85%, specificity of 95.83%, and diagnostic accuracy of 74%.

Conclusion:

The current study results suggests that IL-6 and IL-8 levels measured within 24 h of admission can be used for predicting progression to severe acute pancreatitis.
