Abstract Tityus serrulatus scorpion is responsible for a significant number of envenomings in Brazil, ranging from mild to severe, and in some cases, leading to fatalities. While supportive care is the primary treatment modality, moderate and severe cases require antivenom administration despite potential limitations and adverse effects. The remarkable proliferation of T. serrulatus scorpions, attributed to their biology and asexual reproduction, contributes to a high incidence of envenomation. T. serrulatus scorpion venom predominantly consists of short proteins acting as neurotoxins (α and β), that primarily target ion channels. Nevertheless, high molecular weight compounds, including metalloproteases, serine proteases, phospholipases, and hyaluronidases, are also present in the venom. These compounds play a crucial role in envenomation, influencing the severity of symptoms and the spread of venom. This review endeavors to comprehensively understand the T. serrulatus scorpion venom by elucidating the primary high molecular weight compounds and exploring their potential contributions to envenomation. Understanding these compounds' mechanisms of action can aid in developing more effective treatments and prevention strategies, ultimately mitigating the impact of scorpion envenomation on public health in Brazil.

Abstract The article analyzes the strategic uses of Resumo Escolar, published in 1929, in addressing teachers and students, understanding it as a pedagogical device for the dissemination and implementation of the principles of school reform in Espírito Santo. Based on the evidentiary method (Ginzburg, 2002), it uses as sources: seven editions of the investigated journal, government reports, school inspection reports and journalistic materials. In the context of the educational reform produced in Espírito Santo between 1928 and 1930, it is understood that the editorial project of Resumo Escolar and its strategic uses by the Secretariat of Public Education, conform it as a box of utensils (Carvalho, 2006) that conveyed the new man ideal and the didactic-pedagogical guidelines that would guide local schools.

RESUMEN Introducción: La cirugía laparoscópica ginecológica permite intervenir a la paciente sin tener que abrir el abdomen, pues consiste en realizar pequeñas incisiones. Actualmente se emplea en enfermedades como el cáncer o en la extracción de quistes y miomas, por lo que se puede aplicar en casi cualquier intervención de cirugía ginecológica. Objetivo: Caracterizar los procedimientos laparoscópicos del Servicio de Ginecología en el Hospital Materno-Infantil Ángel Arturo Aballí en el período comprendido entre enero del 2018 y diciembre del 2021. Métodos: Se realizó un estudio observacional, descriptivo, retrospectivo de corte longitudinal con el fin de describir la actividad asistencial laparoscópica. La muestra fue de 180 pacientes, según el criterio de selección no probabilístico de los investigadores. Resultados: La edad promedio fue 41,6 años. Según los antecedentes, predominó el tamaño del útero con 91,1 % (n = 164). Dentro de las indicaciones quirúrgicas, se encontró la paridad satisfecha en un 34,4 %, seguido del tumor de ovario (18,9 %), las neoplasias intraepiteliales cervicales (13,4 %) y el fibroma uterino sintomático. En cuanto a la cirugía mayor, se encontró la histerectomía abdominal laparoscópica en un 49,0 % (n = 78), seguido de la salpingectomía con un 38,9 %, resultados con significación desde el punto de vista estadístico (p = 0,004). En cuanto a la cirugía menor, el 11,6 % de la muestra recibió la ablación de los focos endometriales. Las complicaciones fueron escasas. Conclusiones: Los procederes laparoscópicos del Servicio de Ginecología del Hospital Materno-Infantil Ángel Arturo Aballí se consideraron adecuados de acuerdo a los indicadores quirúrgicos.

ABSTRACT Introduction: Laparoscopic gynecological surgery allows for the patient to undergo surgery without having to open their abdomen, since it consists in making small incisions. It is currently used in diseases such as cancer or in the removal of cysts and myomas; therefore, it can be applied in almost any gynecological surgery. Objective: To characterize the laparoscopic procedures of the gynecology service at Hospital Materno-Infantil Ángel Arturo Aballí, in the period from January 2018 to December 2021. Methods: An observational, descriptive, retrospective and longitudinal study was carried out in order to describe the laparoscopic assistance activity. The sample consisted of 180 patients, according to the researchers’ nonprobabilistic selection criteria. Results: The mean age was 41.6 years. Concerning antecedents, uterine size predominated, with 91.1% (n = 164). Among surgical indications, satisfied parity was found in 34.4%, followed by ovarian tumor (18.9%), cervical intraepithelial neoplasms (13.4 %) and symptomatic uterine fibroid. With respect to major surgery, laparoscopic abdominal hysterectomy was found in 49.0 % (n = 78), followed by salpingectomy, with 38.9%; such results are statistically significant (p = 0.004). Regarding minor surgery, 11.6% of the sample received ablation of endometrial focuses. Complications were rare. Conclusions: The laparoscopic procedures of the gynecology service at Hospital Materno-Infantil Ángel Arturo Aballí are considered adequate according to the surgical indicators.

Triclosan (TCS) is a chlorinated diphenyl ether and a possible active agent against microorganisms. Due to its probability of reducing dental plaque accumulation, TCS can be added as a substance for oral hygiene. Aim To evaluate the efficacy and antimicrobial capacity of TCS against Pseudomonas aeruginosa and Streptococcus mutans. Methods This work evaluates the percentage of bacteria inhibition of P. aeruginosa (ATCC 27853) and S. mutans (ATCC 25175). TCS concentrations between 2 and 128 µg.mL-1 were tested. Results An inhibitory potential of TCS was found against S. mutans. No percentage of inhibition was detected against P. aeruginosa (technical and biological triplicate). Conclusion TCS, an antimicrobial agent used in dentifrices, can reduce S. mutans levels therefore these dentifrices should be indicated for patients with a high risk of caries. However, further study is needed, including antimicrobial analyses against other microbial conditions.

O mapeamento da produção científica e tecnológica dos docentes de uma universidade é essencial para compreender a dinâmica que envolve a produção intelectual, tanto para os pesquisadores quanto para a universidade e sociedade, além de ser quesito para recomendação e avaliação de cursos de graduação e pós-graduação. Neste artigo, apresenta-se o mapeamento e análise da produção científica e tecnológica dos docentes de carreira de Magistério Superior da Universidade Federal de Roraima (UFRR), no período de 2015 a 2020. Trata-se de um estudo descritivo quantitativo, constituído por dados relacionados à produção científica (artigos, livros e capítulos) e tecnológica (ativos de Propriedade Intelectual) de 595 currículos disponibilizados na Plataforma Lattes. Este estudo contribui de forma teórica e empírica com a apresentação da evolução de produção científica e tecnológica dos docentes da UFRR, em que se identificaram 3756 produções no sexênio. Apesar da crescente produção no período analisado, ressalta-se a discrepância entre o quantitativo de produção científica (n= 99,7%) e a tecnológica (n= 0,3%). No aspecto qualitativo, foi identificada uma baixa quantidade de produções nos estratos superiores do Qualis Periódicos, apesar do crescimento de 167% de artigos publicados em periódicos Qualis A1. Este estudo demonstra a importância de realizar análise da produção científica das instituições, objetivando um planejamento estratégico e inovador, a fim de aprimorar e incentivar a produtividade científica e tecnológica docente.

The mapping of the scientific and technological production of university professors is essential to understand the dynamics that involves intellectual production, both for researchers, university and society, in addition to being a requirement for recommendation and evaluation of postgraduate and graduate degrees. This article mapped and analyzed the scientific and technological production of Higher Education professors at the Federal University of Roraima (UFRR), from 2015 to 2020. This is a quantitative descriptive study, consisting of data related to scientific (articles, books, book chapters) and technology production (Intellectual Property assets) of 595 curriculum available on the Lattes Platform. This study provides, in a theoretical and empirical way, to the presentation and evolution of the scientific and technological production of UFRR professors, where 3756 productions were identified in the six-year period. Despite the increasing production, the discrepancy between the quantitative of scientific production (n= 99.7%) and technological production (n= 0.3%) stands out. In the qualitative aspect, a low number of productions was identified in the upper stratum of Qualis journals, despite the 167% growth in articles published in Qualis A1 journals. This study demonstrates the importance of performing the analysis of the scientific production of the institutions aiming a strategic and innovative planning in order to improve and encourage the professors’ scientific and technological productivity.

Abstract Introduction: subarachnoid hemorrhage (SAH) is a rare and life-threatening cerebrovascular disease. Mitigating the factors that compromise patient recovery during neurocritical care due to SAH is of clinical benefit. Objectives: to evaluate the nutritional risk of patients with aneurysmal subarachnoid hemorrhage using “The Modified Nutrition Risk in the Critically Ill” (mNUTRIC) score, and examine its association with outcomes such as mortality, time of mechanical ventilation, and functional status among survivors. Methods: we designed a cross-sectional study. Patients with SAH admitted to the neurointensive critical care unit (neuroICU) in a tertiary care public hospital were eligible. The inclusion criteria were a minimum stay in the intensive care unit (ICU) of 24 hrs for subarachnoid hemorrhage from a nontraumatic, spontaneously ruptured cerebral aneurysm, and hospital admission within 24 hrs after the onset of symptoms. Results: high nutritional risk as stratified by the mNUTRIC score was associated with discharge type (OR = 0.346; 95 % CI = 0.182-0.650; p = 0.001), acute hypertensive hydrocephalus (OR = 4.371; 95 % CI = 2.283-8.549; p < 0.001), and functional outcome (OR = 0.106; 95 % CI = 0.025-0.0388; p < 0.001). The mNUTRIC score was significantly different among median age (p < 0.001), length of stay in the neuroICU (p = 0.005), SOFA score (p < 0.001), and APACHE II score (p < 0.001) categories. Conclusions: this study demonstrated an association between nutritional risk assessment and outcomes such as length of stay in the neuroICU, type of discharge, functional status, and mortality prediction accuracy.

Resumen Introducción: la hemorragia subaracnoidea es una forma rara de enfermedad cerebrovascular que pone en peligro la vida del paciente. Reducir los factores que comprometen la recuperación de los pacientes durante los cuidados neurocríticos tiene benefício clínico. Objetivo: evaluar el riesgo nutricional de los pacientes con hemorragia subaracnoidea por aneurisma utilizando la puntuación “The Modified Nutrition Risk in the Critically Ill” (mNUTRIC) y su asociación con resultados como la mortalidad, el tiempo de ventilación mecánica y el estado funcional entre los supervivientes. Método: diseñamos un estudio transversal. Fueron elegibles los pacientes con hemorragia subaracnoidea ingresados en la unidad de cuidados críticos neurointensivos (neuroUCI) de un hospital público de atención terciaria. Los criterios de inclusión fueron una permanencia mínima de 24 horas en la UCI, hemorragia subaracnoidea por rotura espontánea no traumática de aneurisma cerebral, e ingreso hospitalario en las 24 horas siguientes al inicio de los síntomas. Resultados: el alto riesgo nutricional estratificado por la puntuación mNUTRIC se asoció con el tipo de alta (OR = 0,346; IC 95 % = 0,182-0,650; p = 0,001), la hidrocefalia hipertensiva aguda (OR = 4,371; IC 95 % = 2,283-8,549; p < 0,001) y el resultado funcional (OR = 0,106; IC 95 % = 0,025-0,0388; p < 0,001). La puntuación mNUTRIC presentó diferencias estadísticamente significativas entre las medianas de edad (p < 0,001), duración de la permanencia en la neuroUCI (p = 0,005), puntuación SOFA (p < 0,001) y puntuación APACHE II (p < 0,001). Conclusión: este estudio demuestra una asociación de la evaluación del riesgo nutricional con resultados como la necesidad de ventilación mecánica, la duración de la permanencia en la neuroUCI, el tipo de alta, el estado funcional y la precisión en la predicción de la mortalidad.

ABSTRACT Background: Complex trauma is a worldwide health problem and when hemorrhagic, mortality is higher than other types of complex trauma. Objective: To determine predictive variables of early mortality in hospitalized patients with complex hemorrhagic trauma in a second care level hospital in Cuba. Methodology: A cross-sectional study was conducted at Camilo Cienfuegos Provincial General Hospital in Sancti Spíritus, for 6 years. 207 patients were included. The variables were grouped into sociodemographic, associated chronic diseases, injury mechanism, type of trauma, topographic location, time between hospital admission, diagnosis and treatment, early complications, medical and surgical treatment, and early mortality. A decision tree was developed using the exhaustive Chaid method, the dependent variable was mortality due to complex hemorrhagic trauma. Results: Male patients (85 %), 60 years and younger (83 %), with blunt trauma (57.5 %) and polytraumatized patients (42.5 %) predominated. Those who presented metabolic acidosis (66.7 %), acute coagulopathy (44.4 %), and hypothermia (41.5 %) also predominated. 30 % of patients died early. The decision tree had a sensitivity of 82.3 %, a specificity of 97.2 % and an overall percentage of correct forecast of 92.8 %. Four variables that predicted mortality were identified: hypothermia, metabolic acidosis, acute coagulopathy, and penetrating trauma. Conclusions: The highest probability of early dying during a complex hemorrhagic trauma occurs among patients with hypothermia, metabolic acidosis, acute coagulopathy and penetrating trauma.

RESUMEN Fundamento: El trauma complejo es un problema de salud a nivel mundial y cuando es de tipo hemorrágico la mortalidad es superior a los otros tipos de traumas complejos. Objetivo: Determinar las variables predictoras de mortalidad precoz en pacientes hospitalizados con trauma complejo hemorrágico en una institución hospitalaria del segundo nivel de atención en Cuba.

Predominaron también los que presentaron acidosis metabólica (66.7 %), coagulopatía aguda (44.4 %), hipotermia (41.5 %). El 30 % de los pacientes falleció precozmente. El árbol de decisión tuvo una sensibilidad de 82.3 %, una especificidad de 97.2 % y un porcentaje global de pronóstico correcto del 92.8 %. Se identificaron 4 variables predictores de mortalidad: hipotermia, acidosis metabólica, coagulopatía aguda y trauma penetrante. Conclusiones: La probabilidad más alta de fallecer precozmente durante un trauma complejo hemorrágico se da entre pacientes con hipotermia, acidosis metabólica, coagulopatía aguda y trauma penetrante.

ABSTRACT Background: Chronic obstructive pulmonary disease (COPD) is a health problem and the third cause of death in the world. Mortality is higher in patients who present exacerbations of this disease. Objective: To determine mortality predictors in hospitalized patients with exacerbation of COPD in a second care level hospital in Cuba. Methodology: A cross-sectional study was conducted at Camilo Cienfuegos Provincial General Hospital in Sancti Spíritus, for two years. 335 patients were included. The variables collected were grouped into sociodemographic, clinical, associated chronic diseases and patient status at discharge. A decision tree was developed using the exhaustive Chaid method, the dependent variable was mortality from COPD. Results: Female patients (55.2 %), 60 years or older (79 %) and with more than 4 exacerbations in the last year (53.1 %) predominated. The decision tree model had a sensitivity of 97 %, a specificity of 89.3 %, and an overall percentage of correct diagnosis of 93.1 %. Six variables that predicted mortality were identified: acute respiratory failure, diagnosis of pneumonia, non-use of antithrombotics, pulmonary thromboembolism, age over 60 years, and smoking. Conclusions: The highest probability of dying during an exacerbation of COPD occurs among patients with acute respiratory failure, those who are diagnosed with pneumonia during admission, those who do not receive antithrombotic treatment and those who are over 60 years of age.

RESUMEN Fundamento: La enfermedad pulmonar obstructiva crónica (EPOC) es un problema de salud y constituye la tercera causa de defunción en el mundo. La mortalidad es mayor en los pacientes que presentan exacerbaciones de esa enfermedad. Objetivo: Determinar los factores predictores de mortalidad en pacientes hospitalizados con exacerbación de EPOC en una institución hospitalaria del segundo nivel de atención en Cuba. Metodología: Se realizó un estudio transversal en el Hospital General Provincial Camilo Cienfuegos de Sancti Spíritus, durante dos años. Se incluyeron 335 pacientes. Las variables recogidas se agruparon en sociodemográficas, clínicas, enfermedades crónicas asociadas y estado del paciente al egreso.

Resultados: Predominaron los pacientes del sexo femenino (55.2 %), con 60 años o más (79 %) y con más de 4 exacerbaciones en el último año (53.1 %). El modelo del árbol de decisión tuvo una sensibilidad de 97 %, especificidad de 89.3 % y un porcentaje global de pronóstico correcto del 93.1 %. Se identificaron seis variables predictores de mortalidad: insuficiencia respiratoria aguda, diagnóstico de neumonía, no utilización de antitrombóticos, tromboembolismo pulmonar, edad mayor de 60 años y el hábito de fumar. Conclusiones: La probabilidad más alta de fallecer durante una exacerbación de EPOC se da entre los pacientes con insuficiencia respiratoria aguda, los que son diagnosticados con neumonía durante el ingreso, los que no realizan tratamiento antitrombótico y los que tienen más de 60 años de edad.

ABSTRACT Flexible ureteroscopy is a well-established method for treatment of urinary stones but flexible ureteroscopes are expensive and fragile devices with a very limited lifetime. Since 2006 with the advent of digital flexible ureteroscopes a great evolution has occurred. The first single-use flexible ureteroscope was launched in 2011 and new models are coming to the market. The aim of this article is to review the characteristics of these devices, compare their results with the reusable devices and evaluate the cost-benefits of adopting single-use flexible ureteroscopes in developing countries. Materials and Methods: an extensive review of articles listed at PubMed and published between 2000 and 2021 was performed. Results: Single-use flexible ureteroscopes have a shaft with 65 to 68cm length and weight between 119 and 277g. Their deflection goes up to 300 degrees. Their stone-free rates vary between 60 and 95% which is comparable to reusable scopes and operative times ranges from 54 to 86 minutes which are lower when compared to reusable flexible scopes. Their costs vary between 800 and 3180 US dollars. Conclusion: single-use flexible ureteroscopes are lighter and have superior quality of image when compared to fiberoptic ones. There are no definite data showing a higher stone-free rate or less complications with the use of single-use flexible ureteroscopes. Each institution must perform a cost-benefit analysis before making the decision of adopting or not such devices depending on the local circumstances.

ABSTRACT Over the years, vaccinations have provided significant advances in public health, because they substantially reduce the morbimortality of vaccine-preventable diseases. Nevertheless, many people are still hesitant to be vaccinated. Brazil is a region of many anti-vaccine movements, and several outbreaks of vaccine-preventable diseases, such as yellow fever and measles, have occurred in the country during the last few years. To avoid new outbreaks, immunization coverage must be high; however, this is a great challenge to achieve due to the countless anti-vaccine movements. The World Health Organization has suggested new actions for the next decade via the Immunization Agenda 2030 to control, reduce, or eradicate vaccine-preventable diseases. Nonetheless, the vaccination coverage has decreased recently. To resolve the anti-vaccine issue, it is necessary to propose a long-term approach that involves innovative education programs on immunization and critical thinking, using different communication channels, including social media. Cooperation among biology and health scientists, ethicists, human scientists, policymakers, journalists, and civil society is essential for an in-depth understanding of the social action of vaccine refusal and planning effective education measures to increase the vaccine coverage.

Resumo Este estudo apresenta uma teoria substantiva que se propõe a explicar como interagem e que fatores influenciam os elementos envolvidos no processo de implantação, manutenção e evolução da acreditação hospitalar. A pesquisa foi realizada entre os anos de 2015 e 2017, por meio do case do Hospital Regional Público da Transamazônica (HRPT), localizado em Altamira (PA), região Norte do Brasil. Entrevistas, análise documental e observação participante ocorreram de forma longitudinal num período de 24 meses, espaço de tempo que compreendeu a manutenção do nível 2 da acreditação hospitalar no HRPT, bem como a evolução ao nível 3 e sua manutenção. Sob um viés construtivista e qualitativo, o levantamento de dados foi dividido em 5 rodadas, conforme as diretrizes da grounded theory na vertente de Charmaz, e envolveu 56 participantes. O modelo proposto, denominado “comprometimento com o cuidado”, se mostrou uma alternativa integradora e sistêmica à compreensão de como ocorre a acreditação hospitalar na organização estudada. Sua estrutura é constituída por 3 categorias centrais - “a forma como trabalhamos”, “acreditação como instrumento de ação” e “amor à causa” -, 1 categoria de suporte - “desenvolvimento dos profissionais de saúde” - e 2 categorias de resultado - “excelência nos resultados” e “cuidado centrado no paciente”. Esses achados dialogaram com o pensamento complexo e o estudo das instituições.

Abstract This study presents a substantive theory that aims to explain the factors that interact and influence the elements involved in the implantation, maintenance, and evolution of hospital accreditation. The study was carried out between 2015 and 2017, through the case of the Transamazonica Regional Public Hospital (HRPT), located in Altamira (state of Pará), in the northern region of Brazil. Interviews, documentary analysis, and participant observation were conducted longitudinally over a period of 24 months, a period that comprised the maintenance of level 2 of hospital accreditation in HRPT, and the evolution at level 3 and its maintenance at this level. Under a constructivist and qualitative bias, data collection was divided into five rounds, according to the guidelines of Charmaz grounded theory, and involved 56 participants. The proposed model, called “Commitment to Care,” was an integrative and systemic alternative to understanding how hospital accreditation occurs in the organization studied. Its structure consists of three central categories: “The way we work,” “Accreditation as an instrument of action,” and ‘Love to the cause’; a category of support: ‘Development of health professionals’; and two outcome categories: “Excellence in Outcomes” and “Patient-Centered Care.” These findings were in dialogue with complex thinking and the study of institutions.

Resumen Este estudio presenta una teoría sustantiva que tiene como objetivo explicar los factores que interactúan e influyen en los elementos involucrados en el proceso de implantación, mantenimiento y evolución de la acreditación hospitalaria. La investigación se llevó a cabo entre 2015 y 2017, a través del caso del Hospital Regional Público da Transamazônica (HRPT), ubicado en Altamira (estado do Pará), norte de Brasil. Las entrevistas, el análisis de documentos y la observación participante se llevaron a cabo longitudinalmente durante un período de 24 meses. Este período de tiempo abarcó el mantenimiento del nivel 2 de la acreditación hospitalaria en el HRPT, así como la evolución al nivel 3 y su mantenimiento en ese nivel. Bajo un sesgo constructivista y cualitativo, el levantamiento de datos se dividió en cinco rondas, según las directrices de la teoría fundamentada de Charmaz, e involucró a 56 participantes. El modelo propuesto, llamado Compromiso con el Cuidado, demostró ser una alternativa integradora y sistémica a la comprensión de cómo se da la acreditación hospitalaria en la organización estudiada. Su estructura consta de tres categorías centrales: ‘La forma en que trabajamos’, ‘La acreditación como instrumento de acción’ y ‘Amor a la causa’; una categoría de apoyo: ‘Desarrollo de profesionales de la salud’; y dos categorías de resultados: ‘Excelencia en los resultados’ y ‘Atención centrada en el paciente’. Estos resultados dialogan con el pensamiento complejo y el estudio de las instituciones.
