Management of Intracanal Separated Instruments Using Ultrasonics: A Case Series
Authors: Ikhabi Weboko Fredrick , Kiptoo Kiptiony Lawrence , Wandera Grace Mukami
Published: October 2024

Cleaning and shaping of the root canal system is an important step in non-surgical endodontic treatment. One of the mishaps associated with this step is intracanal instrument separation. Endodontic instruments separation often results from overuse or incorrect use. Such an event impedes shaping, disinfection and subsequent filling of the canal space apical to the instrument fragment. The use of ultrasonics has shown appreciable success for management of these cases especially when supported with magnification and illumination. With adequate knowledge, suitable armamentaria, fine clinical skills, and experience successful management of such cases, without further complications, is possible. If not well managed, intracanal separated instrument fragments adversely affect the long-term treatment outcome of endodontically treated teeth. This report presents three cases with intracanal separated instruments which were successfully managed with the use of ultrasonics under magnification with dental loupes.

Authors: Petrishchev Yu. I. , Malkova O. G. , Levit A. L.
Published: October 2024

Introduction. The question of the possibility of predicting the severity of multiple organ failure that developed in the postoperative period in cardiac surgery patients is not sufficiently covered in the literature.The aim of the study is determine the prospects of studying the relationship between the level of biomarkers and the severity of multiple organ failure in patients undergoing cardiac surgery.Materials and methods. A series of seven observations was carried out on the clinical course of the immediate postoperative period in patients who underwent elective cardiac surgery. In the preoperative period, the risk of in-hospital mortality was assessed using the EuroSCORE II scale and the presence of multiple organ failure using the SOFA scale. Before surgery and at the beginning of the first postoperative day, the plasma level of presepsin was studied. Also, at the beginning of the first postoperative day, plasma levels of transferases and troponia T were studied, and the severity of multiple organ failure was analyzed using the SOFA scale. The length of stay of patients in the ICU was assessed. The results of the study are presented in the form of tables and graphs and subjected to visual analysis.Results. The obtained data do not allow us to accurately link the level of tissue damage markers (aspartate aminotransferase, alanine aminotransferase, troponin T) and the marker of the systemic inflammatory reaction presepsin with the severity of multiple organ failure in patients after cardiac surgery. At the same time, they do not exclude the existence of such a connection.

Authors: C. O. Akpoduado, , P. O. Boyitie,
Published: October 2024

The study assessed household perception of climate change on economic activities in Ughelli North Local Government Area of Delta State. Systematic sampling technique was employed to administer 291 copies of structured questionnaires to households in the area. Data obtained from the administered questionnaire were analyzed using simple percentages, tables, and principal components analysis (PCA). Results obtained showed that households in the area were knowledgeable of climate change. The study revealed that households perceived the impacts of climate change to include increased temperature (55%), decreased rainfall (22.7%), and decreased rainfall duration (12.4%). The study further identified households’ perceived changes in economic activities to include decreasing working hours engaged in economic activities, decrease in food crop farming/fish farming, drastic changes in principal sources of income and livelihood, changes in crop yields and productivity and changes in availability of fodder and non-timber forest product (NTFPs), as well as decrease in workforce productivity. PCA results identified the use of herbicide/insecticide, burning of fossil fuel and deforestation, gas flaring and bush burning as main anthropogenic factors responsible for 80.2% of climate change phenomena in the area. Based on the findings, the study recommended that the government should encourage soft loans to farmers and fish farmers. This will ensure the steady supply of food, thereby increasing households’ source of livelihood and nutrition.

Published: October 2024

The paper looks into the adoption and implementation of cryptocurrency and how it can be influenced by digital leadership. Understanding cryptocurrency awareness, acceptance, and adoption is crucial in today's evolving digital financial landscape. The paper emphasizes this while awareness plays a pivotal role in the acceptance and adoption of new technologies. Building on this foundational understanding, studies examining technology implementation have reaffirmed the positive. The use of cryptocurrencies offers attractive business opportunities in the context of financial services, smart contracts, and token-based business models. Strategies for cryptocurrency adoption in contemporary businesses include commitment to innovation as a relative advantage, cryptocurrency compatibility within the organization, overcoming the complexity of adoption, and control of corruption. The crypto industry saw a number of adoption milestones in 2023, from institutional interest to more nuanced regulations. The paper engages the use of Diffusion Innovative theory and Game theory as its theoretical framework, as well as the use of descriptive and content analysis. The paper then concludes on various ways on how digital leadership could aide adoption and implementation of cryptocurrency in the world today.
The Relationship Between Patient-Reported Outcome Measures (PROMs) in Patients Undergoing Hip and Knee Joint Replacement Surgery and Social Deprivation on the Wirral
Authors: GOMPELS B , DONNACHIE N
Published: October 2024

Objective: This study aimed to investigate the associa-tion between patient-reported outcome measures (PROMs), both pre- and post-operatively, and socio-economic deprivation among patients undergoing hip and knee replacement surgeries in the diverse socioeconomic region of Wirral.

Methods: A retrospective cohort study was conducted, involving 1666 adult patients who underwent hip or knee replacement procedures between 2012 and 2019. Socioeconomic deprivation was assessed using the Index of Multiple Deprivation (IMD). Pre- and post-operative outcomes were measured using the Oxford Hip and Knee scores.

Results: The mean scores for both pre-and post-operative assessments (Q1 and Q2) exhibited a strong positive correlation with PROM scores, regardless of gender, across both hip and knee replacements. However, the mean difference in scores between Q1 and Q2 showed no significant correlation with the IMD decile. Notably, patients residing in areas of higher socioeconomic deprivation demonstrated lower PROMs both before and after the surgery.

Conclusion: The Oxford Hip and Knee scores are widely employed for evaluating health status in patients. In our study, these scores were influenced by IMD decile, supporting the holistic assessment approach employed by the treating unit, which does not rely solely on PROM scores as a trigger for arthroplasty discussions. Furthermore, our findings align with the practice of NHS Digital, which publishes PROM scores based on changes in PROM scores pre- and post-operation rather than absolute PROM scores. This approach appears to be less influenced by deprivation in the catchment area, as the improvement or change in scores was poorly correlated with socioeconomic factors.

Este artigo aborda a formação de professores/as alfabetizadores/as, com o objetivo de analisar os desafios e possibilidades na formação de professores/as alfabetizadores/as a partir das políticas educacionais. Defende-se a perspectiva de alfabetização atrelada ao letramento e fundamenta-se em autores como Soares (2003, 2004, 2018), Mortatti (2000, 2015), Piccoli (2015), Martiniak, Brisola e Padilha (2022), e Hoça, Romanowski e Cartaxo (2016). A pesquisa segue uma abordagem qualitativa, com reflexões teóricas baseadas em revisão bibliográfica e análise documental. Os resultados indicam que a formação de alfabetizadores/as é essencial para uma alfabetização eficaz e integrada às práticas sociais. Contudo, identificam-se lacunas curriculares na formação inicial e ressaltam-se a relevância das políticas de formação continuada, como o PNAIC e o PNA para superação de tais lacunas. Entre os desafios, destacam-se as abordagens tradicionais e a descontinuidade das políticas educacionais, as quais acrescentam novos nomes aos programas sob diferentes governos, mas mantêm formatos similares e o distanciamento com as universidades, enquanto instituições formadoras.
Stock price prediction portfolio optimization using different risk measures on application of genetic algorithm for machine learning regressions
Authors: Gandomi Amir Hossein , Sadjadi Seyed Jafar , Amiri Babak
Published: October 2024

This research aims to enhance portfolio selection by integrating machine learning regression algorithms for predicting stock returns with various risk measures. These measures include mean-value-at-risk (VaR) variance (Var), semi-variance mean-absolute-deviation (MAD) and conditional value-at-risk (C-VaR). Addressing gaps in existing literature. Traditional methods lack adaptability to dynamic market conditions. We propose a hybrid approach optimized by genetic algorithms. The study employs multiple machine learning models. These include Random Forest, AdaBoost XGBoost, Support Vector Machine Regression (SVR) K-Nearest Neighbors (KNN) and Artificial Neural Network (ANN). These models are used to forecast stock returns. Utilizing monthly data from the Tehran Stock Exchange, the results indicate that the genetic algorithm prediction model combined with mean-VaR, Var semi-variance and MAD, produces the most efficient portfolios. These portfolios offer superior returns with minimized risk compared to other models. This hybrid strategy provides a robust and efficient method for investors aiming to optimize returns while managing risk effectively. To implement this approach successfully it is crucial to balance investments. This involves both traditional and alternative asset classes, ensuring diversification. It also capitalizes on market opportunities. Regular review and adjustment of fund allocation are essential. Maintain an optimized strategy for maximum returns and minimal risk.
Volatility patterns of stock prices

Published: October 2024

Research on stock exchange markets is essential to stock market investors as it offers sensitivities to risk management. This research investigates the patterns of the volatility of stock market prices in ten African stock markets. We estimated the dynamic GARCH model of Engle using the method of maximum likelihood estimation. Daily time series from January 1, 2021 to December 30, 2022, were obtained from African Stock (Securities) Exchange database. The findings established the existence of a normally distributed Senegalese stock market as against time-varying volatility of stock prices in Nigeria, Ghana, Mali, Burkina Faso, Togo, Niger Republic, Benin Republic, Ivory Coast, and Gambian. Hence, the likelihood that an asset or stock is being overpriced (overvalued) or underpriced (undervalued) in the Senegal stock market is low. It is therefore easier for stock traders and investors in Senegal to pick entry and exit points. Unfortunately, this cannot be said of the investors in stock markets of other countries. In effect, the closing price of a stock is most often heavily deviated with significant outliers. This further infers that variations of stock prices in these markets are very wide, heavy, and unpredicted. Hence, it is a case of the volatility of volatilities.
Lipoprotein, Cholesterol, Treatment Strategies, and its Impact on Cardiovascular Diseases
Authors: Mankar S. D. , B. Pawar Vaishnavi , Y. Pawar Trupti
Published: October 2024

A main cause of death internationally, cardiovascular (CV) illness accounted for about 31.4% of fatalities worldwide in 2012. According to estimates, a 33% decline in coronary heart disease (CHD) mortality in the United States between 1980 and 2000 was caused by a decrease in total cholesterol levels. Similar declines in CHD fatalities (varying from 19% to 46%) in other wealthy nations have been linked to lower total cholesterol levels. Lipoproteins are complex particles with a central core containing cholesterol esters and triglycerides surrounded by free cholesterol, phospholipids, and apolipoproteins, which facilitate lipoprotein formation and function. However, numerous individuals do not achieve LDL-C goal values because of statin resistance or adherence to statin medication. If cholesterol targets are not achieved with statins alone, alternative medicines include ezetimibe, fibrates, and nicotinic acid. In addition, people with familial high cholesterol levels (FH). Lipoprotein may act as a proinflammatory mediator that augments the lesion formation in atherosclerotic plaques. HDL metabolism represents a major target for the development of therapies intended to reduce the risk of atherosclerotic cardiovascular disease. Individual cardiovascular preventative treatments should be targeted largely at individuals at higher risk who will benefit most, with the prevention and treatment of dyslipidemia being viewed as a crucial component of those interventions. Since statins have been demonstrated to lessen the risk of serious vascular events by lowering low-density lipoprotein cholesterol (LDL-C), they continue to be the first-choice medication.

Published: October 2024

Dissolvability assumes an essential part in accomplishing the imperative grouping of prescription in the circulation system to exhibit pharmacological impacts, as it includes the course of a strong substance dissolving in a fluid stage to make a uniform combination. The essential test experienced in forming drugs is the restricted watery solvency of novel medication particles. At the point when inadequately dissolvable medications are managed orally, higher portions are expected to achieve the ideal helpful plasma fixation. Administrative bodies and wellbeing associations use the Bio drug Order Framework to classify intensifies in light of their dissolvability and penetrability. This order framework is utilized to lay out bio equality for substances that are exceptionally dissolvable and profoundly penetrable, involving disintegration for the purpose of evidence. Drugs displaying poor watery solvency experience slow disintegration rates, bringing about commonly low bio accessibility upon oral organization. This survey article expects to investigate methodologies for accomplishing successful ingestion and improving bio accessibility. This article examines different procedures and techniques for working on the dissolvability of inadequately solvent medications. Solvency is essential for a medication's successful fixation at the objective activity site. The decision of strategy relies upon the medication's temperament, properties, and pharmacokinetic conduct. Different strategies can be utilized separately or in mix to further develop drug dissolvability. The decision of strategy relies upon the medication's quality, viability, and relationship with different synthetic compounds, dependability, and final result yield, while likewise thinking about financial variables.

Pandemics have been in the history of mankind wiping out large number of people. COVID-19 pandemic in the 21st century has also taken a heavy toll on lives and has impacted every aspect of life. There have been several short-term and long-term implications on the families. Many families are still experiencing an ongoing negative impacts viz., loss of job, loss and threatened loss of loved ones, financial insecurity etc. Families were unable to meet the demands of children and elderly at home while being grateful for the quality time spent with family members. Material and Method: A comparative cross-sectional study was carried out to measure the level of resilience among families faced with and without COVID-19 infection during the pandemic in selected rural areas of Tamil Nadu, South India. FRS-16 was used to measure the resilience. Results: The study findings regarding the overall resilience revealed that 53% of the families had moderate resilience and 47% had high resilience. However, there was no statistical difference observed in the different domains of resilience such as Family Communication and Connectedness, Positive Framing and External Resources/Support between the families faced with and without COVID-19 infection. Discussion: The findings of this study corresponded to the findings of a study done in Indonesia with 68.9% of the families having moderate resilience during the COVID-19 pandemic. It has also been observed that a positive framing, family communication and connectedness have a positive influence on the family resilience. Conclusion: Family Resilience is a complex process; hence it is of high importance that adaptive strategies are enhanced in families to strengthen them in rising from adversities.

Published: October 2024

Children represent the nation’s investment and future, destined to become the leaders of tomorrow. Introducing Pancasila values at an early age is essential to nurturing competent individuals with strong character and noble morals. This article explores how integrating Pancasila values in early childhood education can contribute to realizing Indonesia's vision for a “Golden Generation 2045.” Employing a descriptive qualitative approach, this study uses library research methods to gather data. The findings highlight that the incorporation of Pancasila values in early childhood can be effectively achieved through the Merdeka Curriculum, where structured play activities serve as a foundation for learning. By aligning stimulating play with children’s interests, their potential can be fully optimized. Moreover, the Pancasila Ideology Education and Development Book (PPIP) provides a critical resource for enhancing understanding of the Pancasila ideology, ultimately strengthening the nation's cultural resilience and fostering the development of a progressive, modern, and morally grounded society.
Exascale Geostatistics for Environmental Data Science
Authors: Genton Marc G.
Published: October 2024

Environmental data science relies on some fundamental problems such as: 1) Spatial Gaussian likelihood inference; 2) Spatial kriging; 3) Gaussian random field simulations; 4) Multivariate Gaussian probabilities; and 5) Robust inference for spatial data. These problems develop into very challenging tasks when the number of spatial locations grows large. Moreover, they are the cornerstone of more sophisticated procedures involving non-Gaussian distributions, multivariate random fields, or space-time processes. Parallel computing becomes necessary for avoiding computational and memory restrictions associated with large-scale environmental data science applications. In this talk, I will explain how high-performance computing can provide solutions to the aforementioned problems using tile-based linear algebra, tile low-rank approximations, as well as multi- and mixed-precision computational statistics. I will introduce ExaGeoStat, and its R version ExaGeoStatR, a powerful software that can perform exascale (10^18 flops/s) geostatistics by exploiting the power of existing parallel computing hardware systems, such as shared-memory, possibly equipped with GPUs, and distributed-memory systems, i.e., supercomputers. I will then describe how ExaGeoStat can be used to design competitions on spatial statistics for large datasets and to benchmark new methods developed by statisticians and data scientists for large-scale environmental data science. This initiative is part of the “Ph.D. Lectures” activity of the project "Departments of Excellence 2023-2027" of the Department of Mathematics of Politecnico di Milano. This activity consists of seminars open to Ph.D. students, followed by meetings with the speaker to discuss and go into detail on the topics presented at the talk.
A demographic assessment of the Lansing Effect in duckweed (Lemna turionifera Landolt)
Authors: Dutt Priyanka , Laird Robert
Published: October 2024

The Lansing Effect is the propensity for offspring of older parents to have shorter lifespans than offspring of younger parents. A recent review identified two demographic patterns that can produce the Lansing Effect: (1) a greater offspring mortality rate at all offspring ages in offspring of older versus younger parents (greater initial mortality parameter); and (2) an offspring mortality rate that increases more rapidly with offspring age in offspring of older versus younger parents (greater mortality rate parameter). Here, we report on a longitudinal study designed to investigate these patterns, using the duckweed *Lemna turionifera*. We tracked asexually produced offspring that detached from parents that were comparatively young versus old (first versus fifth offspring, respectively). Offspring of older parents lived 15% shorter, on average, than offspring of younger parents, providing evidence of the Lansing Effect. A model-selection approach revealed that the difference between survival curves of first versus fifth offspring was mainly attributable to greater initial mortality in fifth compared to first offspring, though alternative models also received some support. Our study provides a demographic explanation for the Lansing Effect in *L. turionifera* in particular, and provides a method for assessing the survival patterns underpinning the Lansing Effect in general.

Published: October 2024

O expansionismo de empresas brasileiras, especialmente pela América Latina, vem produzindo manifestações de descontentamento com o “imperialismo” brasileiro, presentes em movimentos sociais, trabalhos acadêmicos e meios de comunicação latino-americanos. E tem chamado atenção certa retomada da “teoria” do subimperialismo de Ruy Mauro Marini, perspectiva que padece de muitas imprecisões e dificuldades, na obra do autor e na retomada atual. A fim de discorrer brevemente sobre o assunto, na primeira parte do artigo resumimos a perspectiva leninista de imperialismo, de identidade entre capitalismo monopolista e imperialismo; em seguida, na segunda parte, o foco é a noção de subimperialismo de Marini, defendendo não ser possível conferir à noção status teórico e apontando para dificuldades na retomada atual do autor.

Pour Marx e Lire le capital
Authors: Motta Luiz Eduardo
Published: October 2024

O presente texto tem como objetivo fazer uma análise comparativa de duas obras pioneiras de Althusser, nas quais ele lançou novas luzes e questões a respeito da teoria marxista, oferecendo uma leitura inovadora e marcada por uma radicalidade não somente teórica, mas também política. Assim, demarcarei tanto os aspectos similares e convergentes dessas duas obras em relação à critica ao humanismo teórico, como também as suas diferenças. Essa distinção fica marcada pelos conceitos de contradição sobredeterminante, presente em Pour Marx, e o de causalidade estrutural, conceito esse marcante em Lire le Capital. Parto do princípio de que o conceito de contradição sobredeterminante tornou-se fundamental para a compreensão da conjuntura política e de seus aspectos de crise, particularmente nos momentos revolucionários, enquanto o de causalidade estrutural, por extrair o papel da contradição, possui um caráter formalista, o qual Althusser irá retificar em obras posteriores.

Para tanto, identifica a origem do processo nas manifestaçõesde junho de 2013. Na sequência, discute o papel da Operação Lava Jato na legitimação de métodos de exceção, os quais se apresentaram como formas de garantir a ideologia meritocrática. Por fim, aponta o fortalecimento de um campo liberal-conservador, em defesa da família e da propriedade privada, que permitiu tanto ampliar a base social do bolsonarismo quanto atender ao programa neoliberal do capital financeiro.
Filosofia da história ou método histórico? Os usos do marxismo nas controvérsias entre Julio Antonio Mella, Victor Raúl Haya de La Torre e José Carlos Mariátegui (1927-1930)
Authors: Kaysel André
Published: October 2024

Este artigo procura reconstituir os termos que organizaram as controvérsias, ocorridas no final dos anos 1920, entre três importantes intelectuais e militantes das esquerdas latino-americanas da época: o cubano Julio Antonio Mella e os peruanos Victor Raul Haya de La Torre e José Carlos Mariátegui. Indagarei pelos usos que cada um fez do marxismo, bem como a vinculação dessas apropriações com os problemas substantivos que organizaram as discussões, como os da atuação do imperialismo e do caráter da revolução na América Latina. Pretendo demonstrar que embora Mella e Haya de La Torre se opusessem em seus diagnósticos políticos, ambos entendiam o materialismo histórico como filosofia da história, divergindo sobre sua aplicabilidade ou não à região. Já Mariátegui, em sua polêmica com Haya de La Torre, atrelaria suas discrepâncias programáticas a uma compreensão distinta do marxismo, tomado enquanto método de interpretação da realidade, o que lhe permitiria superar a oposição entre universalismo e particularismo. Por fim, procurarei fazer um balanço dessas controvérsias à luz de diferentes leituras da história do marxismo latino-americano.

Drug allergies pose significant risks to patient safety and effective healthcare delivery. This comprehensive review explores the pivotal role of nursing in the identification, documentation, and management of patient drug allergies. Through a detailed analysis of current practices, protocols, and case studies, we highlight the essential contributions of nurses to drug allergy management. Key areas include methods of allergy identification, best practices for documentation, effective communication strategies, and the education of both patients and healthcare team members. The review also addresses the challenges nurses face, such as systemic barriers and gaps in education and training, and provides recommendations for policy improvements, enhanced educational programs, and the integration of technological solutions. By understanding and enhancing the role of nursing in managing drug allergies, we can improve patient safety and outcomes. Future research directions are suggested to address existing knowledge gaps and further support nursing practices in this critical area.

Background: Asthma and chronic obstructive pulmonary disease (COPD) are prevalent chronic conditions significantly impacting healthcare costs and patient quality of life. Inhalation therapy plays a crucial role in managing these diseases, with a wide array of devices available for medication delivery. Aim: This review aims to update the understanding of nebulizers, inhalers, and spirometers in managing asthma and COPD, highlighting device usage, patient adherence, and clinical outcomes. Methods: A comprehensive literature review was conducted, focusing on the effectiveness, usability, and patient adherence associated with various inhalation devices, including nebulizers, pressurized metered-dose inhalers (pMDIs), and dry powder inhalers (DPIs). Patient preferences and common user errors were also analyzed. Results: Findings indicate a significant prevalence of incorrect inhalation techniques, which adversely affect treatment outcomes. Despite the growing market for inhalation devices, non-adherence remains a challenge, particularly among patients with cognitive impairments. User errors were common across all device types, highlighting the need for improved patient education and device selection tailored to individual capabilities. Conclusion: Optimizing inhalation techniques and enhancing patient education are essential for improving clinical outcomes in asthma and COPD management. Future strategies should focus on personalized device selection and ongoing support to foster adherence and correct usage.

Objetivo: identificar los factores de riesgo de caries dental en niños preescolares con labio y paladar fisurado. Metodología: estudio de tipo analítico transversal donde participaron 70 niños de 3 a 6 años con FLAP que fueron atendidos por el servicio de odontopediatría de la Organización No Gubernamental Qorito (Lima-Perú), de enero a diciembre del 2022. Las variables analizadas fueron caries dental, higiene oral, dieta, tipo de fisura, sexo, edad. Los análisis aplicados fueron la evaluación de Spearman, la prueba de Chi cuadrado y la regresión logística múltiple. Resultados: la prevalencia de caries dental en niños con FLAP fue del 92,9%. Para esto se empleó un índice que codifica los dientes deciduos como cariados, extraídos y obturados (CEOD) con manchas blancas. Además, se encontró que el tipo de fisura es un factor de riesgo para la caries dental con un (OR) de 3,15. Conclusión: la caries dental tiene una relación significativa con una deficiente higiene oral. A su vez, los niños con labio y paladar fisurado con una buena higiene oral tenían menos probabilidades de desarrollar caries dental que aquellos con una higiene oral deficiente.
Impacto de una intervención educativa en el nivel de conocimiento sobre VIH y otras ITS en la población sexualmente activa de Santo Domingo, Mérida, Venezuela. 2023

La Organización Mundial de la Salud (2023) indica que alrededor de 38 millones de personas sexualmente activas entre 15 y 49 años, tienen una ITS fácilmente curable en la región de las Américas. Objetivo: determinar el impacto de una intervención educativa en el nivel de conocimiento sobre VIH y otras ITS en la población sexualmente activa de Santo Domingo, Mérida, agosto 2023. Metodología: enfoque cuantitativo, tipo analítico, de corte transversal. Se evaluó un total de 28 participantes. Como instrumento de recolección de datos se empleó el cuestionario “ECI”. Resultados: 89,3% de la muestra estuvo constituida por mujeres y 10,7% por hombres; edades comprendidas entre 15 a 60 años, perteneciendo el 42,9% al grupo etario de adultos jóvenes de 19 a 35 años. 41,7% no utilizó ningún método anticonceptivo durante las prácticas sexuales. Solo el 12,5% refirió hacer uso del preservativo como método contraconceptivo. Se obtuvo un cambio significativo con el abordaje (p=0,0001), en los porcentajes de conocimientos entre los individuos antes y después del abordaje. Conclusiones: el nivel de conocimientos en ITS era del 66% y mejoró un 11% tras la intervención educativa. No se encontró una relación significativa entre las variables sociodemográficas con el nivel de conocimientos en la población estudiada. Los hallazgos revelan la importancia de hacer campañas de concientización sobre el uso del condón como principal método anticonceptivo, ya que es el único que funge de barrera y disminuye sustancialmente el riesgo de transmisión de las diversas ITS.

La dermatomiositis es una enfermedad catalogada como rara que forma parte de las miopatías inflamatorias idiopática. Su incidencia es de 1 por cada 100.000 personas por año. Se caracteriza por presentar afectación cutánea y del tejido muscular esquelético. En el caso clínico se muestran los hallazgos neurofisiológicos encontrados en un paciente masculino de 39 años de edad que ingresa al área de emergencia en febrero - 2024 por iniciar con debilidad muscular progresiva, proximal y simétrica con antecedente de aparición de lesiones cutáneas en la región facial, cervical, torácica y en miembros superiores e inferiores un mes antes del inicio de la debilidad muscular. Entre los hallazgos electrofisiológicos es importante resaltar la presencia de signos de denervación en la actividad espontánea dada por abundantes fibrilaciones de ++ a +++ principalmente en músculos proximales como fueron deltoides bilateral y vasto externo izquierdo. La actividad voluntaria destacó la aparición de un patrón mixto (neurógeno- miopático), con potenciales de baja amplitud de manera global, corta y polifásica. Logrando un diagnóstico inicial mediante los hallazgos electrofisiológicos y valor de creatinfosfoquinasa (CK) lo que permitió un inicio precoz en el tratamiento. Diagnóstico que posteriormente fue confirmado con los hallazgos anatomopatológicos de la biopsia muscular. Por lo que es importante resaltar que los estudios electroneuromiográficos son de gran importancia para realizar un diagnóstico temprano que permita al paciente recibir un tratamiento oportuno disminuyendo las posibles complicaciones.
