Effect of preoperative oral bisoprolol on intraoperative outcomes in endoscopic sinus surgery

Background: Endoscopic sinus surgery (ESS) presents challenges in managing intraoperative bleeding and hemodynamic stability. This study evaluates the efficacy of pre-operative oral bisoprolol in improving surgical conditions and outcomes in ESS. Methods: This study was conducted between March 2021 and June 2022 at the department of anaesthesia, Bangabandhu Sheikh Mujib medical University, Dhaka, Bangladesh. This randomized controlled trial was conducted with 50 participants undergoing elective ESS, divided into bisoprolol and placebo groups. Result: The study involved 50 participants undergoing elective ESS, with 25 in the bisoprolol group and 25 in the placebo group. While demographic characteristics, such as age, weight, height, and gender distribution, showed no statistically significant differences between the groups. The placebo group experienced significantly higher estimated blood loss (421.72 ml vs. 156.24 ml, p<0.001) and postoperative hemoglobin levels (12.88 g/dl vs. 11.07 g/dl, p<0.001) compared to the bisoprolol group. Hemodynamic parameters, particularly heart rate, exhibited significant differences at various time points, with the bisoprolol group maintaining a higher heart rate post-premedication, intra-operatively, and post-operatively (p<0.05 for all). In the assessment of intraoperative bleeding using the Fromme-Boezaart scale, the placebo group demonstrated higher incidences of severe bleeding grades (3 and 4) compared to the bisoprolol group, with these differences being statistically significant (p<0.001). Conclusions: Pre-operative oral bisoprolol in ESS patients significantly reduces intraoperative bleeding and anesthetic requirements while maintaining hemodynamic stability. These findings suggest bisoprolol as a beneficial pre-operative medication in ESS, warranting further research to optimize surgical outcomes.

Improved visibility of illuminated chopper-assisted cataract surgery involving iris challenges

Purpose: The aim of this study was to evaluate the efficacy of the illuminated chopper?assisted cataract surgery in terms of shortening the surgical time and reducing the use of pupil expansion devices in eyes with iris challenges. Methods: This was a retrospective case series of a university hospital. Four hundred forty?three eyes of 433 consecutive patients who underwent illuminated chopper?assisted cataract surgery were included in this study. Cases with preoperative or intraoperative miosis, iris prolapse, and intraoperative floppy iris syndrome were included in the iris challenge group. Use of tamsulosin, iris hooks, pupil size, surgical time, and improved visibility (100/surgical time × pupil size) were compared between eyes with and without iris challenges. Mann–Whitney U test, Pearson’s Chi?square test, and Fisher’s exact test were used for statistical analysis. Results: Of 443 eyes, 66 were included in the iris challenge group (14.9%). Tamsulosin use was more common in patients with iris challenges and iris hooks were used more frequently (9.1% vs. 0%, P < 0.001) in patients with iris challenges than in those without iris challenges. Pupil size was smaller in patients with iris challenges (6.01 vs. 7.64 mm, P < 0.001). However, surgical time was not different (16.9 vs. 16.5 min, P = 0.064) between the two groups. As a result, improved visibility was calculated to be higher in patients with iris challenges (1.05 vs. 0.81, P < 0.001). Conclusion: In terms of surgical time and improved visibility, using the illuminated chopper simplified cataract surgery involving iris challenges. The use of an illuminated chopper is expected to be a good solution for challenging cataract surgeries.

A method of mental disorder recognition based on visibility graph / 生物医学工程学杂志

The causes of mental disorders are complex, and early recognition and early intervention are recognized as effective way to avoid irreversible brain damage over time. The existing computer-aided recognition methods mostly focus on multimodal data fusion, ignoring the asynchronous acquisition problem of multimodal data. For this reason, this paper proposes a framework of mental disorder recognition based on visibility graph (VG) to solve the problem of asynchronous data acquisition. First, time series electroencephalograms (EEG) data are mapped to spatial visibility graph. Then, an improved auto regressive model is used to accurately calculate the temporal EEG data features, and reasonably select the spatial metric features by analyzing the spatiotemporal mapping relationship. Finally, on the basis of spatiotemporal information complementarity, different contribution coefficients are assigned to each spatiotemporal feature and to explore the maximum potential of feature so as to make decisions. The results of controlled experiments show that the method in this paper can effectively improve the recognition accuracy of mental disorders. Taking Alzheimer's disease and depression as examples, the highest recognition rates are 93.73% and 90.35%, respectively. In summary, the results of this paper provide an effective computer-aided tool for rapid clinical diagnosis of mental disorders.

Cramér-Rao lower bound of dark-field imaging using a grating interferometer / 中国医学物理学杂志

In grating-based phase contrast imaging,the phase stepping technique is commonly utilized for data acquisition and signal retrieval from acquired intensity data.However,the algorithm efficiency with respect to the dark-field retrieval has yet to be sufficiently evaluated.Herein the algorithm efficiency of dark-field retrieval based on Cramér-Rao lower bound is evaluated.The theoretical analysis and numerical results demonstrates that fully efficient algorithm is currently available only for 3-step phase stepping technique,and other techniques with more phase steps are all sub-optimal.Quantitatively,the dependence of the algorithm efficiency on the phase step number and the visibility is investigated.It is shown that the phase stepping technique can nearly approach its theoretical optimal efficiency in the case of a low visibility.With a phase step greater than 5,the algorithm efficiency is only 77.4%in the case of a high visibility.The study can provide some reference for signal-to-noise ratio improvement and potential dose optimization in X-ray and neutron grating-based dark-field imaging.

Diagnostic value of blue light imaging-bright and linked color imaging for early esophageal cancer / 中华消化内镜杂志

Objective To investigate the diagnostic value of blue light imaging-bright (BLI-bright) and linked color imaging (LCI) for early esophageal cancer (EEC).Methods:Data of 63 consecutive patients with EEC who underwent gastroscopy under BLI-bright, LCI and white-light imaging (WLI) and endoscopic submucosal dissection (ESD) from May 2018 to August 2020 at Fuding Hospital Affiliated to Fujian University of Traditional Chinese Medicine were analyzed retrospectively in the cohort study. Subjective visibility analysis was performed by 6 endoscopists who were divided into 2 groups (expert group and trainee group) with 3 endoscopists in each group. The main observation index was the visibility score (ranking score, RS). The objective color difference (Δ E) between lesions of EEC and surrounding mucosa under 3 modes were analyzed by using the L *a *b * color space. Results:The overall RS of 6 endoscopists under WLI mode (2.57±0.81) was significantly lower than that under LCI (3.25±0.67) ( t=9.71, P<0.001) and BLI-bright (3.18±0.67) ( t=9.31, P<0.001). In the expert group, the RS of WLI (2.71±0.80) was significantly lower than that of LCI (3.33±0.66) ( t=7.16, P<0.001) and BLI-bright (3.42±0.62) ( t=8.09, P<0.001). In the trainee group, the RS of WLI (2.40±0.90) was also significantly lower than that of LCI (3.15±0.83) ( t=9.62, P<0.001) and BLI-bright (2.89±0.92) ( t=5.69, P<0.001), and the RS of LCI was higher than that of BLI-bright ( t=4.07, P<0.001). The Δ E between lesions of EEC and surrounding mucosa under WLI (11.52±3.40) was significantly lower than that under LCI (16.64±4.70) ( t=7.10, P<0.001) and BLI-bright (15.72±3.84) ( t=7.88, P<0.001). Conclusion:BLI-bright and LCI can effectively improve EEC visibility and color difference between EEC and surrounding mucosa. Furthermore, LCI is more conducive to the detection of EEC for the trainees.

Imunização e desigualdade de gênero: a construção da imagem da mulher nos primeiros atos de vacinação contra a covid-19 / Immunization and gender inequality: the construction of the image of women in the first vaccination acts against covid-19 / Inmunización y desigualdad de género: la construcción de la imagen de la mujer en los primeros actos de vacunación contra covid-19

O estudo tem por objetivo analisar as valências simbólicas identificadas em notícias publicadas no Portal G1 de todos os estados brasileiros sobre os primeiros atos de vacinação contra a covid-19, relacionando-os, em particular, às questões de raça e gênero com foco nas mulheres e sua posição na sociedade. Nessa perspectiva busca-se responder, sob a ancoragem da semiótica de Algirdas Julien Greimas, como a mulher foi representada em cada estado. Os resultados retratam as mulheres como sujeito social 'frágil' e 'dependente' do Estado como 'Pai-Provedor' ao lado do uso de mulheres negras representativas de 'minorias' que remetem a uma ideia de um Brasil diverso e miscigenado. As conclusões evidenciam que a visibilidade conferida à mulher nas campanhas de vacinação disputou espaço com representações de caráter sexista e racista.

The study aims to analyze the symbolic valences identified in news published on the G1 Portal from all Brazilian states about the first acts of vaccination against covid-19, relating them to issues of race and gender with a focus on women and their position in society. From this perspective, we seek to answer, under the anchorage of Algirdas Julien Greimas' semiotics, how women were represented in each state. The results portray women as a 'fragile' and 'dependent' social subject, from the State as a 'Father-Provider', alongside the use of black women representing 'minorities' that refer to an idea of a diverse and miscegenated Brazil. The conclusions show that the visibility given to women in vaccination campaigns disputed space with sexist and racist representations.

Desde esta perspectiva, buscamos responder, bajo el anclaje de la semiótica de Algirdas Julien Greimas, cómo estaban representadas las mujeres en cada estado. Los resultados retratan a la mujer como sujeto social 'frágil' y 'dependiente' del Estado como 'Padre-Proveedor' junto con el uso de mujeres negras representativas de 'minorias' que remiten a una idea de un Brasil diverso y mestizo. Las conclusiones muestran que la visibilidad dada a las mujeres en las campañas de vacunación disputaba espacio con representaciones sexistas y racistas.

Las limitaciones de Scopus como fuente de indicadores: Buscando una visibilidad integral para revistas argentinas en ciencias sociales / Limitations of Scopus as a source of indicators: In search for a more comprehensive understanding of the visibility of Argentinian social science journals

Resumen En este trabajo se avanza en la definición de un conjunto de indicadores para medir la visibilidad de las revistas científicas de ciencias sociales de manera integral. Para esto, se considera el uso de fuentes diversas que permitan conocer la citación, la accesibilidad y los alcances de las publicaciones. Se toman como muestra 11 revistas de ciencias sociales editadas en Argentina incluidas en el SCImago Journal & Country Rank. Se analizan sus posiciones en el ranking y el número de citas de esta base y se lo compara con datos recogidos en Google Scholar utilizando la herramienta Publish or Perish. Además, se sistematiza información acerca de su accesibilidad e indicadores de uso y métricas alternativas de sus propios portales, de SciELO, Redalyc y de la base de datos Dimensions. Se pone en evidencia la parcialidad del impacto medido desde Scopus para este grupo de revistas y se demuestra que, al combinar las fuentes, se amplían y diversifican los datos de visibilidad. Para finalizar, se proponen una serie de indicadores básicos de visibilidad integral a partir de las fuentes disponibles que permiten a los gestores de revistas ofrecer datos más certeros de la citación y usos de las revistas y sus artículos.

Abstract This work seeks proposes a group of indicators that can be used to understand the visibility of social science journals in a more comprehensive way. To this end, the use of various sources of data pertaining to citation, accessibility, and reach are considered. A sample of 11 social science journals published in Argentina and indexed in Scimago Journal & Country Rank is used. The ranking and number of citations found in Scopus are analyzed and compared against data obtained from Google Scholar using the Publish or Perish tool. In addition, data regarding the accessibility and use, as well as alternative metrics, are collected from SciELO, Redalyc, and Dimensions and systematized. The analysis highlights the limited ways in which impact is measured using Scopus data and shows that, by combining data from additional sources, new dimensions of visibility are made apparent. The article concludes with a proposal for a new set of comprehensive visibility indicators that rely on freely available data and allow journal managers and editors to offer a more complete picture of the citational impact and use of their journals and articles.

Las locuras puerperales: una lectura comparada entre Argentina y Colombia, 1880-1950 / Puerperal insanity: a comparative reading of Argentina and Colombia, 1880-1950

Resumen El objetivo es comprender la aparición y propagación de locuras puerperales en Argentina y Colombia, a finales del siglo XIX y principios del XX, así como su decadencia o desvanecimiento hacia la década de 1940-1950. Investigación histórico-hermenéutica, según los conceptos de "campo de visibilidad" y "nicho ecológico" de una enfermedad transitoria. No existió correlación entre embarazo, parto y puerperio con el estado delirante que motivaba la internación, atribuido a factores predisponentes y, asimismo, tuvieron una autonomía nosográfica en virtud de etiopatogenias singulares. Al tiempo que empezó a emerger el tipo clínico locura puerperal, se entrecruzaron el campo disciplinar de la obstetricia con el alienismo, con una mayor preponderancia del primero.

Abstract Our goal is to understand the appearance and spread of forms of puerperal insanity in Argentina and Colombia in the late nineteenth and early twentieth century, as well as their decline or disappearance around the 1940s. This is a historical and hermeneutical study, which uses the concepts of "field of visibility" and "ecological niche" for a transitory disease. There was no correlation between pregnancy, childbirth and puerperium and the state of delirium that led to commitment, which was attributed to predisposing factors; furthermore, forms of puerperal insanity were nosographically distinct due to their unique etiopathogeneses. As clinical cases of puerperal insanity started to emerge, the disciplinary field of obstetrics converged with psychiatry, with the former exerting more weight.

Sementes lançadas em terras distantes: a garantia do direito à assistência social para a população rural / Seeds thrown in distant lands: guaranteeing the right to social assistance for the rural population

O artigo aborda a (in)visibilidade do rural na garantia do direito à assistência social, por meio de uma investigação orientada pelo Materialismo Histórico Dialético, que analisou a Constituição Federal de 1988, a Lei Orgânica de Assistência Social (LOAS), de 1993, a Política Nacional de Assistência Social (PNAS) e as Normas de Operação Básica da Assistência Social (NOB-SUAS), aprovadas respectivamente em 2004 e 2012, e entrevistou profissionais e usuários do Sistema Único de Assistência Social. O presente estudo revela que o direito à assistência social para a população rural vem se constituindo de modo insuficiente, uma vez que a precarização da política de assistência social, sob a égide do neoliberalismo, se intensifica no rural, além da (in)visibilidade do rural, enquanto um fenômeno pluridimensional, uma vez que a classe trabalhadora que vive no rural encontra-se nessa relação contínua entre invisibilidade e visibilidade, em processos dialeticamente simultâneos

The article addresses the (in) visibility of the rural in guaranteeing the right to social assistance, through an investigation guided by Dialectical Historical Materialism, which analyzed the Federal Constitution of 1988, the Organic Law of Social Assistance (LOAS), of 1993, the National Social Assistance Policy (PNAS) and the Basic Social Assistance Operation Standards (NOB-SUAS), approved respectively in 2004 and 2012, and interviewed professionals and users of the Unified Social Assistance System. The present study reveals that the right to social assistance for the rural population has been insufficiently constituted, since the precariousness of the social assistance policy, under the aegis of neoliberalism, intensifies in the rural area, besides the (in) visibility of the rural population. rural, as a multidimensional phenomenon, since the working class that lives in rural are in this continuous relation between invisibility and visibility, in dialectically simultaneous processes

Removable partial dentures: eliminating retainers in the anterior zone / Prótesis parcial removible: eliminación de retenedores en la zona anterior

Abstract Introduction: one of the main factors for discomfort in users of removable partial prosthesis is the presence of visible retainers in the anterior zone. In Kennedy Class III arches, that is, exclusively dental loading pathways (in which the functional forces reach their final receptor: the alveolar bone), anterior zone retainers may be eliminated by selecting an appropriate prosthetic insertion and removal axis, and mainly by carving guiding planes that should provide retention by mechanical rubbing. This in vitro experimental study aimed to prove the hypothesis that it is possible to obtain functional retention in a dental-loading pathway removable partial prosthesis without using retainers in the anterior zone. Methods: 7 maxillary models with different types of toothless process were used. As a common characteristic, they all were classified as Kennedy Class III with partial denture arches. A Cr-Co metallic base was built for each model according to their clinical situation. Their design allowed them to be exposed to traction in a universal traction machine (Tinius Olsen H5K-S). Results: the proposed hypothesis was confirmed as expected. The traction force needed to displace the metallic bases with retainers in the anterior zone was 16.93 Newton in average. On the other hand, the metallic bases without retainers in the anterior zone showed an average of 12.84 N. The average values obtained for both groups are higher than those reported in the literature (4.903 N). Conclusions: in Class III removable partial dentures it is possible to use metallic bases with no retainers in the anterior zone.

Resumen Introducción: un factor que incomoda a los usuarios de prótesis parciales removibles es la presencia de retenedores visibles en la zona anterior. En clases III de Kennedy, es decir, vías de carga exclusivamente dentarias, sería posible eliminar los retenedores del sector anterior mediante un adecuado tallado de planos guías que brinde retención por roce mecánico y la elección de un eje de inserción y remoción protésico. Este trabajo es un diseño experimental in vitro que tiene por finalidad validar la hipótesis propuesta por nuestro equipo de investigación, que es posible obtener retención funcional en una prótesis parcial removible de vía de carga dentaria sin utilizar retenedores en el sector anterior. Métodos: se utilizaron 7 modelos maxilares en yeso tipo IV, con distinto tipo de desdentamiento, cuya característica común era que correspondían a clases III de Kennedy de arcos parcialmente desdentados. A cada modelo se le confeccionó una base metálica de Cr-Co, de acuerdo con sus características clínicas individuales, las cuales presentaron un diseño que permitió utilizarlas en una máquina de tracción universal para someterlas a fuerzas de tracción. Resultados: la fuerza de tracción necesaria para desalojar las bases metálicas que contaban con retenedores en el sector anterior fue del orden de 16,93 N en promedio. En cambio, las bases metálicas sin retenedores en el sector anterior presentaron un valor promedio para su desalojo de 12,84 N. Conclusiones: los valores promedio obtenidos para ambos grupos son superiores a los que se señala en la literatura (4,903 N) como válidos para una retención adecuadamente funcional para una prótesis parcial removible.

A (in)visibilidade da mulher negra youtuber / The (in)visibility of the black female youtuber / La (in)visibilidad de la mujer negra youtuber

Discutindo sob o viés interseccional, o artigo busca expor a problemática da invisibilidade midiática das mulheres negras youtubers dentro do contexto da cultura participativa. Identificamos e observamos canais de mulheres youtubers a partir do recorte das temáticas do feminismo e empoderamento feminino, e realizamos um estudo descritivo com abordagem quanti-qualitativa, analisando as aproximações e distanciamentos dos canais a partir das categorias de alcance, interação e temática. Conclui-se que as youtubers negras interagem de forma mais significativa do que as youtubers não negras, o que não interfere no alcance dos canais, visto que as youtubers negras possuem dados de alcance inferior às youtubers não negras. Observamos que mesmo podendo atingir todas as mulheres, as falas das youtubers negras podem ser entendidas com enfoque na questão racial, enquanto isso, identificamos um discurso universal do 'ser mulher' nas falas das youtubers não negras, fator que pode contribuir para o alcance expressivo.

Discussing under the intersectional bias, the article seeks to expose the problem of media invisibility of black women youtubers within the context of participatory culture. We identified and observed channels of female youtubers from the cut of the themes of feminism and female empowerment, and we conducted a descriptive study with quantitative and qualitative approach, analyzing the approximations and distances of the channels from the reach, interaction and thematic categories. It is concluded that black youtubers interact more significantly than non-black youtubers, which does not interfere with the range of the channels, as black youtubers have lower range data than non-black youtubers. We note that even though it can reach all women, the black youtubers' speeches can be understood with focus on the racial issue, meanwhile, we identified a universal discourse of 'being a woman' in the non-black youtubers speeches, a factor that can contribute to the expressive reach.

Se concluye que las youtubers negras interactúan de manera más significativa que las youtubers no negras, lo que no interfiere con el rango de los canales, ya que las youtubers negras tienen datos de rango más bajos que las youtubers no negras. Observamos que, aunque puede llegar a todas las mujeres, los discursos de las youtubers negras se pueden entender con un enfoque en el tema racial, mientras que identificamos un discurso universal de 'ser mujer' en los discursos de las youtubers no negras, un factor que puede contribuir al alcance expresivo.

Visibilidade de pessoas trans na produção científica brasileira / Trans people visibility in Brazilian scientific production / Visibilidad de personas trans en la producción científica brasileña

Como grupo social estigmatizado, pessoas transgêneras são alvo de violência e invisibilização de suas demandas. Partindo da constatação preliminar de que o discurso científico tem naturalizado e localizado a verdade sobre o gênero nas estruturas corporais, desenvolvemos uma pesquisa, no âmbito de um mestrado acadêmico, cujo objetivo foi caracterizar modos de visibilidade de pessoas trans na produção científica brasileira. A estratégia metodológica foi delinear um panorama dessa produção. O trabalho consistiu na busca de estudos na SciELO CI, na WoS e no Scopus; na análise de autores, instituições, áreas do conhecimento e países envolvidos; e na análise de assunto. O corpus identificado foi de 293 estudos. Os resultados revelam uma diversificação nas áreas de pesquisa e necessidade de atendimento integral adequado, do fomento à pesquisa, de discussão de gênero nas escolas e do cuidado ao nomear grupos estigmatizados. O objetivo do artigo é apresentar esse panorama.

As a result of being a stigmatized social group, transgender people are victmis of violence and invisibility of their demands. Based on the preliminary perception that the scientific discourse has naturalized and localized the truth about gender in the body structures, we developed a research within the scope of an academic master degree whose objective was to characterize modes of visibility of trans people in Brazilian scientific production. The methodological strategy was to outline an overview of this production. The work consisted in searching for studies in SciELO CI, WoS and Scopus; in the analysis of authors, institutions, areas of knowledge and countries involved; and in the subject analysis. The corpus identified was formed from 293 studies. The results reveal a diversification in the areas of research and the need for adequate integral care, promotion of research, gender discussion in schools and care in naming stigmatized groups. The purpose of the article is to present this overview.

Do AZT à PrEP e à PEP: aids, HIV, movimento LGBTI e jornalismo / From AZT to PrEP and PEP: AIDS, HIV, LGBTI movement and journalism / Del AZT a la PrEP y a la PEP: Sida, VIH, movimiento LGBTI y periodismo

O objetivo deste artigo é destacar características e atravessamentos dos movimentos LGBTI brasileiros, da aids, do HIV e de coberturas jornalísticas da síndrome que surgiu publicamente no início dos anos 1980. Resgatamos dimensões históricas e questões atuais como desafiadoras para as ciências, a medicina, governos e militantes com o intuito de refletir sobre disputas que estiveram e estão em curso, principalmente aquelas que se relacionam com a LGBTIfobia e outras opressões sociais. A pesquisa foi realizada por meio de levantamento bibliográfico acerca das políticas do movimento LGBTI, do HIV e da aids, bem como do uso de resultados de pesquisa anteriormente realizada sobre homofobia e narrativas jornalísticas. Observou-se uma conexão complexa entre as relações engendradas no surgimento da síndrome, próxima aos primeiros passos do movimento LGBTI no Brasil, como a produção ambivalente de visibilidades, assim como a manutenção de preconceitos históricos que ainda reverberam no tecido social.

The aim of this article is to highlight the characteristics and crossings of Brazilian LGBTI, AIDS, HIV movements and of journalistic coverage of the syndrome that emerged publicly in the early 1980s. We brought up historical dimensions and current issues as challenging for the sciences, medicine, governments and militants in order to reflect on ongoing disputes, especially those that are related to LGBTIphobia and others social oppressions. The research was carried out through a bibliographical survey about policies of the LGBTI, HIV and AIDS movements, as well as the use of previously conducted research results on homophobia and journalistic narratives. It was observed a complex connection between the relations generated in the beginning of the syndrome, close to the first steps of the LGBTI movement in Brazil, as the ambivalent production of visibility, as well as the maintenance of historical prejudices that still reverberate in social world.
