Authors: Sarmento Maíra Lopes , Granato Maria Julia Filgueiras , Amaral Enzo Bosi Ribeiro , Borges Lara Muniz , Rampinelli Kaio Florentino
Published: May 2024

A síndrome de Guillain-Barré (SGB) é uma condição neurológica rara e potencialmente fatal desencadeada por uma reação imune anormal contra o sistema nervoso periférico, muitas vezes após infecções gastrointestinais ou respiratórias. Os sintomas incluem fraqueza muscular progressiva, arreflexia e, em casos graves, paralisia flácida. A SGB pode ser desencadeada por diversos agentes infecciosos, como Campylobacter jejuni e Zika vírus, além de outros fatores como a vacinação contra a gripe. Embora rara, a SGB tem um impacto significativo nos sistemas de saúde, com custos médicos elevados e uma taxa de incidência estimada em cerca de 1-2 casos por 100.000 pessoas ao ano. O diagnóstico da SGB é baseado em sintomas clínicos e pode ser complementado por exames como eletroneuromiografia e punção lombar. O tratamento envolve o uso de imunoglobulina intravenosa e/ou plasmaferese, que têm demonstrado eficácia na melhoria do prognóstico dos pacientes. No entanto, apesar da disponibilidade desses tratamentos, ainda há necessidade de mais pesquisas para aprofundar o entendimento da doença e investigar novas abordagens terapêuticas, especialmente para casos refratários ou formas variantes da síndrome. A recuperação da SGB geralmente é extensa, mas alguns pacientes podem apresentar queixas residuais e complicações a longo prazo, destacando a importância de uma abordagem multidisciplinar no manejo desses pacientes.

Authors: García-Álvarez Martha Fabiola , Medina-Villarreal Jorge Humberto , Haro-Reyes Dante Jaime , Monroy-Ojeda Carla
Published: May 2024

La vulnerabilidad de las mujeres mexicanas las hace presa fácil de las organizaciones criminales, especialmente las que se trasladan de un lugar a otro y, se asientan en zonas turísticas. Estas mujeres pueden ser objeto del delito de trata, con fines de comercio sexual y de órganos, así como participar en la compra venta de droga. Por lo tanto, el objetivo es analizar la génesis de la criminalidad femenina desde una perspectiva de género víctimas de la violencia, y la influencia de la movilidad femenina en México, sea de manera voluntaria o involuntaria y, las consecuencias de estas acciones. Enfoque teórico-metodológico: es descriptivo, analítico, inductivo-deductivo. Discusión y resultados: se están incrementando las mujeres en el campo criminal, así como la vulnerabilidad en la violencia de las mujeres objeto de acciones criminales en razón al género, teniendo entonces féminas víctimas y victimarias Conclusiones: las mujeres mexicanas son objeto de inseguridad, violencia y vulnerabilidad por el solo hecho de ser “mujer”, con mayor riesgo cuando migran de manera interna donde pueden ser captadas para ejercer la criminalidad o,  convertirse en víctima de algún delito que, ahora en la actualidad son los feminicidios los de mayor riesgo y que se han incrementado. Por lo tanto, es necesario realizar más investigaciones con perspectiva de género, analizando la violencia como fuente de la criminalidad femenina, reconociendo la capacidad de éstas para participar activamente en los delitos; así como, planteando propuestas con estrategias adecuadas y preventivas. Este trabajo es parte de un proyecto de investigación denominado “Migración y Criminalidad”, desde el fenómeno de la criminalidad femenina; basado en los Objetivos del Milenio de la ONU y dentro del marco del Programa Nacional Estratégico (PRONACES), en la línea de investigación “violencias estructurales”.

Published: May 2024

In the 21st century, waste is a growing problem and must be considered one of the essential elements of creating conditions for sustainable development. The article pays special attention to the biofraction of cemetery waste, and interviews with cemetery visitors made a possible determination of its place among other wastes produced in the cemetery. The willingness of cemetery visitors to participate in the logistics of the cemetery waste management system was also tested. The article also presents selected elements of cemetery waste management logistics. The system should consist of several subsystems. Subsystems of waste minimisation "at the source" and waste segregation, disposal, and secondary management were considered crucial. In addition to the logistics mentioned above, subsystems were proposed to include innovation in cemeteries, the biotechnology of composting/vermicomposting of the biofraction, and segregation on-site by those cleaning their graves. The cemetery biofraction represents a waste suitable for on-site management, increasing the potential for environmental, social, and economic savings. The issues under consideration are part of the problem of integrating the cemetery biofraction into the green recycling system in force in Europe. Logistics for management of other cemetery wastes (plastic, metal, glass, and paper), which require subsystems involving their long-distance transportation, should be limited at the level of purchase by cemetery users. From civic participation in the control of logistical improvements, the entire cemetery waste management system will gradually evolve.

Authors: Letik I.V. , Zhuravlyova L.V. , Filonenko M.V. , Klimashevska V.O.
Published: May 2024

Background. White-coat hypertension is a controversial issue of a modern cardiovascular medicine. It is a common condition in clinical practice, in which office blood pressure is elevated while out-of-office measurements (ambulatory or home) are normal.

The aim of this review is to address a number of issues related to white-coat hypertension, in particular, its definition, prevalence, etiology, symptoms, and consequences, emphasizing the need to improve diagnosis, management and prognosis of this disease.

Results. Recent studies demonstrate that white-coat hypertension is associated with cardiovascular risk factors, including the progression to sustained hypertension and the development of target organ damage. Timely and accurate diagnosis of white-coat hypertension is incredibly important as it allows postponing its conversion to sustained hypertension and prevents alterations of target organ structure and function. The need for improved patient-doctor interaction to enhance diagnosis and management of white-coat hypertension cannot be overstated. Other measures include exploring standardized measurements, improving communication and relationship establishing between physicians and patients, as well as investigating innovative interventions such as health education and telemedicine. The importance of the understanding of the emotional components contributing to white-coat hypertension are highlighted and strategies to improve patient outcomes through early diagnosis, reduced anxiety, and optimal healthcare experiences are proposed.

Conclusion. A comprehensive approach, encompassing standardized measurements, improved communication, and innovative interventions, is essential for effectively managing white coat hypertension.

Published: May 2024

La evaluación temporal de la cobertura nivalen las cumbres del noroeste argentino es fundamental para efectuar estudios hidrológicos y estimar el contenido de agua en las cuencas. El clima de las zonas montañosas tiene un papel significativo en la distribución de los recursos hídricos, debido a la altitud y a la circulación atmosférica regional, las temperaturas promedio son más bajas y frecuentes las precipitaciones de granizo y/o nieve. Estas condiciones climáticas tienen una marcada influencia en la preservación de las geoformas presentes en la alta cuenca, tales como vegas, lagunas, prótalus, glaciares cubiertos y glaciares de escombros. El presente trabajo tuvo como objetivo la delimitación de las áreas cubiertas por nieve entre los años 2014 y 2021, con el propósito obtener datos que permitirán caracterizar o identificar zonas criogénicas nivales estacionales, que favorecerían su permanencia. Para el mapeo de la nieve se aplicó el índice NDSI, utilizando las bandas: verde y de infrarrojo de onda corta de las escenas satelitales Landsat 8 OLI-TIRS y Sentinel 2A. Estas escenas incluyen a la sierra del Aconquija, límite entre las provincias de Tucumán y Catamarca. Con el software Qgis2.18.27, se obtuvieron los polígonos que representan las áreas cubiertas de nieve, y con el software gvSIG1.10 se determinaron las alturas máximas y mínimas de nieve para cada año. Los resultados obtenidos muestran que la metodología aplicada permitió mapear la cobertura nival, con limitantes dadas por la presencia de nubes sobre las cumbres.
Design and Development of a Deep Learning Model for Classification of Alzheimer's disease Using Magnetic Resonance Images
Authors: Penuganti HarikaDevi , Satyanarayana Gunupusala
Published: May 2024

Alzheimer’s disease, an incurable neurodegenerative condition predominantly affecting memory functions in the elderly, presents a significant global health challenge, particularly among individuals aged over 65 years. Early and accurate diagnosis is crucial for effective management and intervention. However, manual diagnosis by healthcare professionals is prone to errors and time-consuming due to the increasing number of cases. While various techniques have been employed for diagnosis and classification, there remains a need for improved accuracy in early detection solutions. In this research, we propose a deep learning-based approach utilizing Convolutional Neural Network (CNN) architectures for the diagnosis and classification of Alzheimer’s disease. The proposed model distinguishes Alzheimer’s disease into four categories: Non-Dementia, Very Mild Dementia, Mild Dementia, and Moderate Dementia. The CNN architecture, with optimized hyper parameters, demonstrated superior performance during both training and testing phases, achieving accuracy values of 0.977 and 0.994, respectively. The proposed model offers a practical solution for real-time analysis and classification of Alzheimer’s disease, potentially enhancing early intervention strategies and patient care
SecureZone: Secure and Efficient Multipath Routing for Mobile Ad Hoc Networks
Authors: Sahu Dr. Rani , Sahu Vinay , Chouksey Dr. Pushplata , Jain Sourabh
Published: May 2024

Mobile ad hoc networks (MANETs) represent collaborative networks formed by mobile nodes without a centralized infrastructure, finding application across diverse domains including military and security-sensitive operations. However, securing the routing process within MANETs poses significant challenges due to the absence of a central authority and the dynamic nature of the network. Existing routing protocols suffer from limitations such as bandwidth consumption and route request delays. In response, this paper introduces the Secure and Energy-efficient Zone-based Multipath Routing Protocol (SEZMRPR) for MANETs. SEZMRPR integrates proactive and reactive approaches while incorporating digital signatures and encryption techniques to ensure message integrity, data confidentiality, and end-to-end authentication at the IP layer. The paper provides a comprehensive design of SEZMRPR, assesses its resilience against security attacks, and evaluates its performance through simulations. Results demonstrate SEZMRPR's robustness against security threats, its efficient security performance with acceptable overhead, and its applicability in securing MANETs for military and security-sensitive operations. SEZMRPR, in conjunction with existing security measures, establishes a reliable framework for ensuring secure operations in ad hoc networks. Future enhancements may focus on optimizing performance, scalability, energy efficiency, and addressing quality of service requirements to further refine the protocol.

Nigeria is an agricultural nation, with majority of its citizenry predominantly relied on it for survival. Recently, the sector is receiving a lot of attention due to the need to diversify and a bit away from an oil-driven economy. The sector is one among the most contributing to the nations` Gross Domestic Product (GDP), recording 21% in the previous year. However, one of the causes of low crop yield is diseases caused by agents such as fungi, bacteria, and viruses. The advent of technology has led to its influence in the agricultural sector. The recent evolution and fusion of IOT, ML and Data Analytics has brought succour for especially plant monitoring and management. This research work investigated the capability of IOT, ML and DA in tomato plant disease classification in Yauri Emirate, Northwestern Nigeria. We further conduct a survey with a view to understanding the knowledge, acceptability or otherwise of the mentioned techniques. The result of our classification using CNN, a DL model achieves a near-optimal accuracy of 98.6% with a loss of 0.03% while recording over 98.3 % for both precision and recall on the predicted labels. We also observed that our target audience for the survey lacks near total knowledge of smart farming, hence the need for the stakeholders in the domain to embark on sensitization and awareness towards reaping its numerous advantages

Factorial experimental design based on multiple factors for sensors
and actuators development
Authors: AILENI RALUCA MARIA , STROE CRISTINA
Published: May 2024

This paper presents several use cases for a full factorial experimental design method used in the development of flexible
sensors and actuators. The full factorial experimental designs consisted of 4 factors with discrete values (3–4 levels)
based on known parameters of the experimental devices. In general, the selected factors can influence other dependent
variables. This study aims to investigate the main effects and the interaction effects (antagonistic, synergistic, ceiling)
among the different factors and to optimize an experimental design for reducing the consumption (raw materials, water,
energy, chemicals) and obtaining the optimal values for surface electrical resistance using a reduced number of
experiments. The use of the complete factorial experimental plan and optimization with a minimization function helps to
select, from the set of possible experiments, the experiments including the optimal parameters for obtaining the desired
result. Therefore, the number of experimental plans and the corresponding amount of resource consumption is reduced
(e.g., from 81–256 experiments to 10–20 experiments) while obtaining electroconductive textile electrodes for sensors
and actuators.

Published: May 2024

The fashion industry is well known for being one of the most polluting industries worldwide, and its contribution to textile
waste and apparel consumption has grown in significance over the years. The development and integration of
zero-waste patterns in designing sustainable apparel represent a promising approach that supports reducing
pre-consumer textile waste and optimizing fabric consumption. Moreover, it encourages society to step into a new era
of the garment industry, by shifting the regular way in which consumers are currently perceiving apparel items: a trend,
rather than a need – based on a survey conducted in 2023 by the author. The study focuses on the design principles
and techniques of zero-waste patterns and their impact on fabric utilization. For this study, the patterns have been
digitally drafted and nested, testing the requirements given by the chosen fabric and waste minimization. To acquire a
specific image of the result, consisting of the garment item, has been virtually simulated. This method of obtaining the
product’s prototype aims to highlight and encourage the paradigm shift concerning digitalization that needs to take place
within the manufacturing industry. The results of the study demonstrate that zero-waste patterns can reduce fabric
consumption and significantly reduce pre-consumer waste, but their drafting methods are highly related to the design
process and the chosen fabric’s characteristics, such as usable with or print artwork.

Published: May 2024

This study aims to investigate the effects of different washing processes, twill directions, and yarn types on the
performance properties of denim fabrics. For this purpose, 100% cotton elastane, 85% cotton/15% Modal elastane, and
85% cotton/15% Tencel elastane including denim fabrics were produced with two different weaves (3/1 Z and 3/1 S),
and four different industrial washing operations were applied to these denim fabrics. In addition, untreated fabrics (not
industrially washed) were used to compare the performance of the fabrics before and after industrial washing. The
highest warp-breaking strength values were observed in the rinse-washed fabrics, whereas the highest shrinkage,
elasticity, and rubbing fastness values were observed in the bleach-washed fabrics. In addition, it can be said that
industrial washing processes reduce the growth values of untreated fabrics and reduce the bagging during use. Although
the crystallisation degree of Tencel fibre is higher than that of Modal fibre, it was concluded that the use of Modal fibre
with cotton increased the strength values. In contrast, the use of Tencel fibre with cotton increased the elasticity and
rubbing fastness values of the denim fabrics.

Published: May 2024

As an important part of textile production, the dyeing process not only makes the greatest contribution to water
consumption and wastewater discharge, but its use of synthetic dyestuffs has a negative impact on all forms of life. To
assess the environmental impact of textile production, it is necessary to assess the environmental impact of the dyeing
process. Comprehensive assessment methods can convert multi-dimensional environmental impacts into unified
quantitative indicators and enable comparisons between different products or environmental impact categories. In this
study, five comprehensive assessment methods (i.e., ReCiPe, Eco-Indicator 99, Nike MSI, Environmental Price, and
Environmental Profit & Loss) were applied to evaluate the environmental impact of the cotton fabric dyeing process.
Furthermore, a preliminary assessment framework was constructed which could provide a reference for industry experts
to establish uniform environmental assessment standards. The results indicate that diverse methods are recommended
to be applied in parallel to analyse the environmental impact of textile products, and the use of individual comprehensive
environmental assessment methods has its limitations and characteristics. Among the five methods, the ReCiPe method
stands out as one of the most advanced LCA methodologies with the widest range of midpoint impact categories and a
global-scale calculation mechanism. The scoring method offers sufficient possibilities to compare the severity of different
environmental impacts caused by the dyeing process, and the monetary value model can be used as a more intuitive
tool to characterize environmental impact no matter from the midpoint or endpoint.
La mediación lingüística en las clases de inglés en el nivel universitario: Intervenciones docentes y actividades situadas
Authors:   , Calle Calle María Daniela
Published: May 2024

La globalización y el actual desarrollo económico y tecnológico han transformado el panorama educativo a nivel mundial. Particularmente en el caso de la educación en lenguas, estos fenómenos han traído consigo nuevos beneficios y desafíos. Sin duda, una de las novedades didácticas, es la adopción del llamado Enfoque Cultural o Intercultural en la docencia de lengua extranjera. Dicho enfoque permite introducir la cultura en el aula, puesto que la cultura propia de un determinado grupo social se exterioriza en el uso lingüístico que de ella se hace. Este enfoque más complejo e innovador que el denominado enfoque por destrezas, permite afrontar la enseñanza de lenguas en contextos plurilingües en el que el objetivo no es la excelencia o corrección lingüística del hablante, sino la comunicación eficaz. Actualmente, las competencias lingüísticas efectivas requieren un renovado modelo de aprendizaje lingüístico. En este contexto, la mediación lingüística se concibe como herramienta didáctica tendiente a favorecer y afianzar la adquisición de determinadas destrezas que configuran el enfoque (inter)cultural. La mediación, como actividad de la lengua que actúa de puente entre códigos lingüísticos distintos, se impone así a la vez como una necesidad y una realidad de las sociedades del siglo XXI. En este marco resulta concluyente que, si la educación debe tener como fin dotar al alumno de las habilidades que la sociedad le requiere, la clase de lenguas extranjeras debe incluir la mediación entre las destrezas que debe desarrollar el aprendiz. Por esta razón, el objetivo del presente trabajo investigativo es conocer cuál es el papel de la mediación lingüística en la enseñanza del inglés en el nivel universitario. También se propone identificar qué actividades utilizan los docentes para desarrollar la mediación lingüística y su posición frente a ésta. Este estudio se enmarca en el enfoque de la investigación cualitativa de tipo descriptivo e interpretativo dentro de la metodología de estudio de caso. La investigación se realizó con un grupo de cincuenta y tres docentes del Departamento de Idiomas de la Universidad de Cuenca. Para abordar los objetivos mencionados, se utilizó una encuesta, observaciones de clase, entrevista y el análisis documental en la recolección de datos. En general, se pudo percibir que la mediación lingüística es un tema poco conocido por parte de los docentes y, por lo tanto, fue difícil encontrar actividades de mediación en sus clases. También, a pesar de que la traducción ha vuelto a adquirir importancia como actividad pedagógica, los docentes participantes no han sabido expresar el valor y las posibilidades que ésta ofrece como actividad comunicativa. Al mismo tiempo, la planificación docente se enmarca en el enfoque comunicativo cuyo principal objetivo es el desarrollo de las cuatro destrezas, por lo que la actividad mediadora queda relegada.

Polyparadigmatic uncertainty of international economic relations in the global security system
Authors: Sokhatskyi Oleksandr
Published: May 2024

Introduction. The dominant paradigms of international economic relations remain the market economy, the liberalization of world trade, globalization and the integration of national markets into world markets and their openness, which were supposed to contribute to economic development, increased well-being and sustainable peace on the planet. However, the realities turned out to be the opposite, the economies of the countries of the world are developing unevenly, the gap between rich and poor countries is growing, poverty gives rise to terrorism, and political conflicts began to be resolved by military means.
Goal. The purpose of the article is to justify the state of polyparadigmatic uncertainty in the implementation of international economic relations for the restoration of the global security system in the conditions of global instability, as well as the need for a new reading of known theories and their addition with alternative ideas.
Methods. In accordance with the outlined goal, the article uses general scientific methods of research, in particular, the historical method for analyzing the state of global security for the period from 1946 to 2023 through the prism of the emergence of paradigms of international economic relations. In the process of research, the methodological approach of Thomas Kuhn regarding scientific paradigms, the sequence of creation of new knowledge, starting from the period of initial pre-paradigmality, when there was no single accepted model for the study of scientific problems, to the creation of dominant paradigms, within which the main scientific explorations are carried out in specific time frames, was used.
Results. Six periods of emergence, formation and paradigm changes of international economic relations in the system of global security are distinguished, from the period of initial pre-paradigmaticity to the current state of polyparadigmatic uncertainty.
Prospects. The complexity of the problems raised requires further research into the impact of alternative international economic paradigms on the global security system. In particular, empirical verification of the consequences of their use. Discussions may take place regarding possible new readings of known dominant doctrines or syntheses of them with alternative doctrines.

Published: May 2024

This research aims to optimize product distribution routes in logistics using computer simulation approaches and genetic algorithms. This research produces more efficient distribution routes by utilizing mathematical models that reflect actual distribution processes, including variables such as warehouse locations, distribution points, product types, customer demand, and vehicle availability. Genetic algorithms are used to design optimal solutions with implementation stages, which include solution representation, population initialization, fitness evaluation, selection, crossover, mutation, and stopping criteria. The visualization results show that the genetic algorithm can produce more structured and efficient distribution routes, reducing total travel distance, distribution costs, and delivery time. Statistical analysis supports significant improvements in distribution performance after implementing the genetic algorithm, with substantial reductions in total mileage, distribution costs, and delivery times and substantial improvements in customer satisfaction. Financial analysis shows significant cost savings and positive ROI from investing in genetic algorithms, while sensitivity analysis reveals the impact of critical factors on distribution costs. This research confirms the financial and operational benefits of applying genetic algorithms in product distribution optimization, with significant efficiency, cost savings, and customer satisfaction results.

Clean water is a basic need that is very important for human life. In Indonesia, many clean water companies supply water for community needs. Indonesia's government-owned clean water company has many customers spread across various provinces. This research aims to apply the k-medoids algorithm in clustering PAM customers based on provinces in Indonesia to determine which provinces are included in the low, medium, and high-level clusters of PAM customers. The data used in this research is on the number of PAM customers, the amount of water distributed, and the value of the water distributed from 1998 to 2021 to 34 provinces in Indonesia. This research obtained 3 clusters, namely low, medium, and high-level clusters determined by the number of PAM customers, the amount of water distributed, and the value of the water distributed in each province. Cluster 1 (C1) is a low-level cluster that obtained results from 19 provinces, Cluster 2 (C2) is a medium-level cluster that obtained results from 11 provinces, and Cluster 3 (C3) is a high-level cluster that obtained results from 4 provinces. And get a k-medoids cluster validation value of 0.014846718. In this way, it is hoped that the government can identify areas in each province that require improvement or improvement in making appropriate decisions regarding clean water resources to provide better services to customers

Tikslas. Įvertinti onkologine odos liga sergančių pacientų požiūrį ir elgseną imtis apsaugos priemonių nuo saulės prieš nustatant odos piktybinį naviką ir kaip jie keitėsi nustačius darinio diagnozę. Palyginti šiuos pokyčius skir­tingų lyčių ir odos darinių grupėse.

Metodika. 2023 m. sausio-kovo mėnesiais atliktas anoni­minis anketinis tyrimas, kuriame dalyvavo po odos pik­tybinio susirgimo nustatymo ir skirto gydymo stebimi pacientai, atvykę į gydymo įstaigą pakartotinei konsulta­cijai. Anketa buvo pateikiama ir internete, specializuotose dermatologijos ir onkodermatologijos socialinių tinklų grupėse. Tyrimo dalyviai atsakė į klausimus apie apsau­gos nuo saulės ypatumus prieš ir po darinio diagnozės.

Rezultatai. Tyrime dalyvavo 297 respondentai: 195 mo­terys ir 91 vyras, iš kurių 138 sirgo bazinių ląstelių kar­cinoma, 98 – melanoma, 22 – plokščialąsteline karci­noma. Pacientų, kurie pagrindinių apsaugos priemonių po diagnozės nustatymo ėmėsi pagal rekomendacijas, t. y. dažnai ar visada, buvo nuo 53,52 proc. (n = 152) iki 65,85 proc. (n = 187). Po darinio diagnozės stebėtas daž­nesnis apsaugos nuo saulės priemonių naudojimas (visose grupėse p < 0,05), respondentai dažniau ėmėsi visų ap­saugos būdų su SPF (visose grupėse p < 0,05), išskyrus SPF priemonių naudojimą tik šiltuoju metų laiku grupėje (p = 0,163). Diagnozavus piktybinį odos darinį, moterys dažniau nei vyrai naudojo: 50 ir didesnio stiprumo SPF (p = 0,023); apsaugos priemones su SPF pakartotinai bent kas dvi valandas (p = 0,004); ne tik veidui, bet ir visam kūnui (atitinkamai p < 0,001 ir p = 0,013); dažniau rū­pinosi odos apsauga per metus (p = 0,006), o vyrai linkę dažniau nenaudoti apsaugos priemonių su SPF prieš ir po piktybinio odos darinio diagnozės (atitinkamai p = 0,004 ir p < 0,001). SPF naudojimo įpročiai prieš ir po darinio diagnozės tarp skirtingų odos darinių grupių statistiškai reikšmingai skyrėsi visose SPF naudojimo kategorijose (visose grupėse p < 0,05).

Išvados. Pacientų požiūris į odos apsaugą nuo saulės po onkodermatologinio darinio diagnozės kinta – paci­entai dažniau imasi apsaugos priemonių, t.y. apsaugos priemonių su SPF naudojimas, tiesioginių saulės spin­dulių ir buvimo lauke vidurdienį vengimas, akinių nuo saulės nešiojimas, šviesių bei kūną labiau dengiančių rūbų, galvos apdangalų dėvėjimas. Pacientai dažniau vadovaujasi tinkamo SPF naudojimo taisyklėmis – nau­doja didesnio stiprumo SPF, stengiasi tepti visas saulei pasiekiamas odos vietas, naudoja jas ne tik šiltuoju metų laiku, tepasi pakartotinai bent kas 2 valandas. Moterys linkusios dažniau imtis odą apsaugančių priemonių nei vyrai. Didžiausia dalis pacientų, tinkamai saugančių odą nuo saulės, sirgo bazinių ląstelių karcinoma, o kai kurie − melanoma. Vis dėlto didelė dalis pacientų imasi ne­pakankamai apsaugos nuo saulės priemonių, todėl efek­tyvių elgsenos intervencijų kūrimui reikalingi papildomi tyrimai nustatyti šio elgesio priežastis.

Published: May 2024

Sparčiojo sveikimo programa – tai įrodymais grįstas daugiadalykis požiūris į paciento priežiūrą perioperaciniu laikotarpiu, siekiant pagerinti pooperacinę būklę ir su­mažinti komplikacijų pasireiškimą, trumpinant bendrąją hospitalizacijos trukmę. Šiame straipsnyje informuojama apie sparčiojo sveikimo programos pagrindinius princi­pus ir jų taikymą priešoperaciniu laikotarpiu (pacientų švietimas, būklės įvertinimas ir optimizavimas, lėtinių būklių korekcija, angliavandenių gėrimas, pooperacinio pykinimo ir vėmimo profilaktika, tromboembolinių kom­plikacijų profilaktika), intraoperaciniame etape (stan­dartizuota anestezija, sisteminė antibiotikoprofilaktika, normotermija ir normovolemija, drenų vengimas) bei pooperacinėje priežiūroje (ankstyvas judėjimo ir mai­tinimosi skatinimas, peristaltikos stimuliacija, adekva­tus nuskausminimas). Anesteziologijos vaidmuo yra itin reikšmingas pagrindinių sparčiojo sveikimo programos principų įgyvendinimui.
BUDD-CHIARI SINDROMAS: KLINIKINIS ATVEJIS

Published: May 2024

Budd-Chiari sindromas (BCS) yra reta būklė, kai dėl sumažėjusio venų pratakumo kraujui sunku pasišalinti iš kepenų. BCS klinikinis pasireiškimas yra labai įvai­rialypis – nuo simptomų nebuvimo iki ūmaus kepenų nepakankamumo. Pagrindiniai klinikiniai požymiai su­daro triadą: pilvo skausmas, ascitas ir hepatomegalija. BCS pasižymi aukštu mirtingumo lygiu, jei liga nedia­gnozuojama laiku ir pacientai negydomi. Auksinis BCS diagnostikos standartas yra Doplerio ultragarsinis tyri­mas (UG), kurio pagalba nustatomas sumažėjęs kraujo tėkmės greitis kepenų venose. Diagnozės patvirtinimui galima naudoti ir kitus tyrimus – KT, MRT ar venogra­fiją. Pirmo pasirinkimo BCS gydymas dažniausiai yra medikamentinis skiriant antikoaguliantus, tačiau ilgai­niui pacientams reikalingas intervencinis gydymas, ku­ris parenkamas kiekvienam individualiai. Sergant BCS, labai svarbus ilgalaikis komplikacijų valdymas – ascito kontrolė ir varikozinio kraujavimo prevencija.
