Intra-Stent Thrombosis Secondary to the Allergic Reaction by Contrast in Elective Percutaneous Coronary Intervention, a Rare example of Kounis Syndrome, a Case Report
Authors: Muneeb Arshad Muhammad
Published: January 2025

Background:

Kounis syndrome is the development of ACS secondary to allergic reaction. We are presenting case report of KS that developed due to allergic reaction in patient undergoing elective angiography and resulted in STEMI.

Case Presentation

64year old female underwent elective PCI for angina refractory to anti-anginal therapy. CTCA demonstrated severe Diagonal 2 Coronary artery disease. Due to on-going angina she was listed for coronary angiogram +/- PCI. Iodixanol was used as contrast medium.This revealed severe disease in the D2. Initially drug coated balloon to D2 used. But DCB of D2 causes dissection. We decided to deploy 2.25x24mmDES overlapping with 2.5x14mmDES. Final results were satisfactory. In recovery urticarial rash noticed on her back. IV Hydrocortisone 100mg and IV Chlorphenamine 10mg was administered. Shortly after, she developed chest pain with ST elevation in lead 1 and aVL. She was immediately taken for PCI. Iohexol contrast was administered to the patient. There was acute stent thrombosis, which when re wired allowed flow to be restored and ECG changes to resolve. Patient developed severe hypotension. A widespread urticarial rash noted over the body with peri-orbital and facial swelling. Patient stabilised with iv adrenaline infusion and transferred to CCU. She was started on oral prednisolone. Patient developed pain in right Iliac fossae after removal of the femoral line next day. She developed abdominal distension and severe hypotension. Her CT AP showed large retroperitoneal hematoma with extravasation from external iliac artery. Via interventional radiology lower dose of Iohexol was used and a stent was inserted in EIA. Patient was moved to ICU. She was discharged home 4 days later with dual antiplatelet for 1 year followed by lifelong Aspirin.

Discussion:
This case was diagnosed with KS by Iodixanol as the source of anaphylaxis. There is need to treat KS as a separate entity in ACS guidelines.

Published: January 2025

Analysis of food composition of two owl species (Tyto alba and Strix aluco) in 14 study sites in the years 1998–2024 revealed the presence of 22 species of small mammals. Five species of Soricomorpha (Talpa europaea, Sorex araneus, S. minutus, Neomys fodiens and Crocidura suaveolens), four species of Chiroptera (Myotis myotis, M. nattereri, Eptesicus serotinus and Nyctalus noctula), 12 species of Rodentia (Clethrionomys glareolus, Arvicola amphibius, Microtus arvalis, M. subterraneus, M. agrestis, M. oeconomus, Mus musculus, Rattus norvegicus, Apodemus agrarius, A. sylvaticus, A. flavicollis and Micromys minutus) and one species (Mustela nivalis) of the order Carnivora were found. Three species: S. araneus, M. arvalis and M. musculus clearly dominated in the diet of the T. alba. Forest rodents: C. glareolus, A. flavicollis and in one site M. arvalis were most common in the diet of S. aluco. Noteworthy is the great share of M. agrestis in the diet of S. aluco, which is rarely noted in other regions of the country. Distinctly increased share of Chiroptera (3 species) constituting 10.1% of prey items of T. alba was recorded in one site in Przelewice.

Published: January 2025

Cel: Celem badania było zweryfikowanie powiązań pomiędzy work-life balance (WLB), determinacją (grit) oraz zaspokojeniem potrzeb autonomii, kompetencji i więzi z innymi osobami w pracy a wybranymi aspektami dobrostanu pracowników polskich korporacji w okresie po pandemii COVID-19. Badanie miało na celu zrozumienie, jakie czynniki są powiązane z dobrostanem psychicznym pracowników w zmieniających się warunkach zawodowych.
Metoda: W badaniu wzięło udział 77 kobiet i 44 mężczyzn w wieku 19–68 lat, byli to pracownicy warszawskich oddziałów firm o charakterze korporacji. Badanie przeprowadzono przy użyciu Kwestionariusza Work-Life Balance – oceniającego równowagę pomiędzy życiem zawodowym a prywatnym, Short Grit Scale – do pomiaru poziomu determinacji, Kwestionariusza „Kiedy jestem w pracy” – oceniającego zaspokojenie potrzeb autonomii, kompetencji i więzi z innymi ludźmi oraz Psychological Well-Being Scales – do pomiaru poziomu dobrostanu psychologicznego​. Opracowując dane, wykorzystano analizę regresji wielozmiennowej oraz analizę korelacji rho Spearmana.
Wyniki: Analiza regresji wielozmiennowej wykazała, że istotnymi predyktorami dobrostanu pracowników były: determinacja (beta = 0,41; p < 0,001), zaspokojenie potrzeby relacji z innymi ludźmi (beta = 0,25; p < 0,001), work-life balance (beta = 0,21; p < 0,001) i zaspokojenie potrzeby autonomii (beta = 0,16; p < 0,05). Wykazano też związki analizowanych zmiennych z sześcioma aspektami dobrostanu mierzonymi skalą PWBS Ryff.
Konkluzja: Wyniki badania potwierdzają, że work-life balance, determinacja oraz zaspokojenie potrzeb autonomii, kompetencji i więzi z innymi ludźmi są istotnymi predyktorami dobrostanu psychologicznego pracowników polskich korporacji. W szczególności determinacja i work-life balance mogą mieć znaczący wpływ na poczucie spełnienia i satysfakcji zawodowej. Wyniki te podkreślają znaczenie tworzenia środowiska pracy, sprzyjającego osiąganiu równowagi pomiędzy życiem zawodowym a prywatnym oraz wspierania indywidualnych potrzeb pracowników.
Transcirculation repair of a direct carotid-cavernous fistula in a patient who presented with hydrocephalus: illustrative case
Authors: Shurkhay Vsevolod , King Brandon L. , Auschwitz Tyler S. , Charles Michael , Kalani M. Yashar S.
Published: January 2025

BACKGROUND

Direct carotid-cavernous fistulas (CCFs) are relatively rare but dangerous complications of penetrating traumatic brain injury or maxillofacial trauma. A variety of clinical signs have been described, including ophthalmological and neurological ones. In some cases, severely altered cerebral blood flow can present as massive life-threatening bleeding through the nose, subarachnoid hemorrhage, and/or intraparenchymal hemorrhage. Although intuitively it makes sense that the elevation of venous pressure can obstruct the absorption of cerebrospinal fluid after the formation of a CCF, reports of CCFs presenting with acute acquired hydrocephalus do not exist.

OBSERVATIONS

This case illustrates the development of hydrocephalus in a patient with a direct CCF.

LESSONS

In the absence of a direct path of access to the cavernous sinus due to occlusion of the carotid artery and difficult venous access, a transcirculation route was used to obliterate the CCF and resolve the hydrocephalus in this patient.

Dural perforation and life-threatening central nervous system complications associated with septic arthritis of the lumbar facet joint: illustrative case
Authors: Yan Hirotaka , Murakami Hideki , Yamabe Daisuke , Taguchi Keita , Chida Kohei , Tsuda Keisuke , Suzuki Yoshio , Suzuki Makoto , Chiba Yusuke , Shitogishi Hirokazu , Itabashi Ryo , Maeda Tetsuya , Doita Minoru
Published: January 2025

BACKGROUND

Septic arthritis of the lumbar facet joint (SALFJ) is a rare condition that can lead to serious complications. The authors present an uncommon case in which SALFJ resulted in bacterial meningitis (BM) with hydrocephalus and pyogenic ventriculitis, causing a disturbance of consciousness. Reports describing perforation of the dura mater by an epidural abscess are rare, and the present case offers valuable insights into the management of complex and severe complications arising from SALFJ.

OBSERVATIONS

A 54-year-old woman presented with impaired consciousness and paraplegia. The patient was eventually diagnosed with SALFJ at the left L3–4 facet joint complicated by BM, hydrocephalus, pyogenic ventriculitis, and acute transverse myelitis. Surgery confirmed a dural perforation, enabling direct invasion of the abscess into the central nervous system (CNS). Surgical interventions, including debridement, dural reconstruction, and local antibiotic perfusion, along with systemic antibiotics, significantly improved the patient’s condition.

LESSONS

This case highlights the potential for an epidural abscess of the SALFJ to directly perforate the dura mater, causing severe CNS complications. This emphasizes the importance of prompt diagnosis and appropriate surgical intervention in managing such complex cases. Timely lumbar surgery, combined with targeted antibiotic therapy, can be life-saving in this rare but critical scenario.

A note on the transitivity of parthood
Authors: Varzi Achille C.
Published: January 2025

That parthood is a transitive relation is among the most basic principles of classical mereology. Alas, it is also very controversial. In a recent paper, Ingvar Johansson has put forward a novel diagnosis of the problem, along with a corresponding solution. The diagnosis is on the right track, I argue, but the solution is misleading. And once the pieces are properly put together, we end up with a reinforcement of the standard defense of transitivity on behalf of classical mereology.
Towards ontologies for formalizing modularization and communication in large software systems
Authors: Oberle Daniel , Lamparter Steffen , Grimm S. , Vrandečić D. , Staab S. , Gangemi A.
Published: January 2025

Large software systems are modularized in order to improve manageability. The parts of a software system communicate in order to achieve the desired functionality. To better understand, develop, manage, and maintain the resulting complexity, this paper presents a framework of ontologies. The ontologies range from very general, foundational ones to ontologies that elucidate the specificities of particular modularization and communication paradigms. We support two specific paradigms. First, we define an ontology for software components that may be used in traditional middleware architectures, e.g., application servers. Second, we specify an ontology for Web services. Through the reuse of existing foundational ontologies and our new Core Software Ontology, our proposal offers several advantages. In particular, it avoids the typical shortcomings related approaches exhibit and it allows for the concise definition of commonalities and differences of the two paradigms.

Published: January 2025

On March 14–15, 2006, at the US National Institute of Standards and Technology (NIST) in Gaithersburg, MD, there took place the first Upper Ontology Summit (UOS). This was a convening of custodians of several prominent upper ontologies, key technology participants, and interested other parties, with the purpose of finding a means to relate the different ontologies to each other. The result is reflected in a joint communiqué, directed to the larger ontology community and the general public, and expressing a joint intent to build bridges among the existing upper ontologies in ways designed to increase and rationalize their utilization and to enhance their semantic interoperability. The Upper Ontology Summit was sponsored by NIST, Ontolog, the National Center for Ontological Research (NCOR), MITRE, and many other organizations. The UOS was organized by a committee consisting of Pat Cassidy, Peter Yim, Steve Ray, Dagobert Soergel, and Leo Obrst.
Towards a standard taxonomy of artifact functions

The aim of this paper is to provide a logically accurate and technologically sound taxonomy of artifact functions. To this end, I review one of the recent proposals of such taxonomy: the Reconciled Functional Basis. Since it turns out that this taxonomy involves some serious shortcomings, I attempt to refine it with the help of the conceptual framework of DOLCE, which is a foundational ontology in Knowledge Representation research.
Merging ontologies requires interlocking institutional worlds
Authors: Colomb Robert M. , Ahmad Mohammad Nazir
Published: January 2025

Merging of ontologies is a frequently addressed problem in the ontology literature. This paper argues that in general two even very similar ontologies cannot be merged. Further, where two ontologies can be merged their conceptualizations are special. They are systems of institutional facts which are interlocking. The argument is based on the literature of the federated database problem and on the concepts of speech act and institutional fact.
Ontological considerations of time, meta-predicates and temporal propositions
Authors: Ma Jixin
Published: January 2025

A natural approach to representing and reasoning about temporal propositions (i.e., statements with time-dependent truth-values) is to associate them with time elements. In the literature, there are three choices regarding the primitive for the ontology of time: (1) instantaneous points, (2) durative intervals and (3) both points and intervals. Problems may arise when one conflates different views of temporal structure and questions whether some certain types of temporal propositions can be validly and meaningfully associated with different time elements. In this paper, we shall summarize an ontological glossary with respect to time elements, and diversify a wider range of meta-predicates for ascribing temporal propositions to time elements. Based on these, we shall also devise a versatile categorization of temporal propositions, which can subsume those representative categories proposed in the literature, including that of Vendler, of McDermott, of Allen, of Shoham, of Galton and of Terenziani and Torasso. It is demonstrated that the new categorization of propositions, together with the proposed range of meta-predicates, provides the expressive power for modeling some typical temporal terms/phenomena, such as starting-instant, stopping-instant, dividing-instant, instigation, termination and intermingling etc.
Abstract vs. social roles – Towards a general theoretical account of roles
Authors: Loebe Frank
Published: January 2025

For decades, roles have been discussed and applied in different ways in various fields of computer science, but apparently no consensus on their understanding is available. Thus, role terms like “patient”, “runner”, or “factor” qualify for further investigation, which aims at covering and generalizing recurrent understandings and uses of roles. The generality of roles suggests their inclusion in top-level ontologies. This paper extends and refines analyses of roles for the top-level ontology General Formal Ontology (GFO). The primary foundation of this account comprises the notions of role, player, and context and their interrelations, associated with situations of, for instance, some human who plays a patient role in a hospital context. Further, a classification of roles is introduced, which at top distinguishes two role types: abstract roles, providing a means of viewing something in a context, and social roles, which are complex social objects in vaguely defined contexts. These types are mixed in the literature, and their differences restrict the theory common to all roles. Based on this framework, the paper discusses controversial issues of roles, demonstrating the expressiveness of the overall account, which allows for fine-grained distinctions and the integration of prior work.
A precise model for contextual roles: The programming language ObjectTeams/Java
Authors: Herrmann Stephan
Published: January 2025

A number of proposals exist concerning how to support the concept of roles at the level of programming languages. While some of these proposals indeed exhibit very promising properties, the concept of roles has not found its way into mainstream programming languages. We argue that this is due to the richness of the concept of roles and the fact that each existing proposal focuses on some aspects of roles while neglecting others. We present the programming language ObjectTeams/Java and using the categories of Steimann (2000) we demonstrate that this language covers more aspects of roles than previous approaches. We suggest that a thoroughly defined programming language featuring roles may contribute to a better understanding also in other fields using roles.
Is an OWL ontology adequate for foreign software agents communication?
Authors: Bermúdez Jesús , Goñi Alfredo , Illarramendi Arantza , Santini Simone
Published: January 2025

This paper presents a formal ontology which intends to facilitate interoperability among agents belonging to software agent systems that use different agent communication languages. The followed design criteria for building the ontology are an elaboration on the “illocutionary force-plus-content” framework of speech acts theory. The ontology is specified in OWL. Reasons are presented through the paper why, in our opinion, an ontology based on speech acts theory and specified in a DL-based language is adequate for formal agent communication. The ontology is divided into three layers: upper, standards and applications, grouping classes by different levels of abstraction. The formalism used in the specification of classes allows automated reasoning for locating classes in the taxonomy and recognizing individuals of classes.
The model of roles within an ontology development tool: Hozo
Authors: Mizoguchi Riichiro , Sunagawa Eiichi , Kozaki Kouji , Kitamura Yoshinobu
Published: January 2025

One of the major goals of ontology is to represent properly the underlying conceptual structure of the messy world reflecting the reality as much as possible. Ontology building tools should be designed to help developers create good ontologies. However, few of them can deal with roles adequately. Needless to say, the world is full of roles (e.g., wife, teacher, president, fuel, food, product, output, height) although there has been extensive theoretical research on roles, we do not yet have a comprehensive and usable theory yet. Our group has already constructed an ontology-development tool known as Hozo which has the ability to deal with roles. However, although Hozo allows users to represent roles better than other existing tools, the underlying theoretical foundations are still unclear and there is some room for improvement concerning the generality of how to deal with roles. In this paper, as an extension of the Hozo framework for roles, we present a framework for organizing role concepts according to their context dependencies. We also focus on the clarification of role properties and requirements on the model of roles and on the feedback obtained from Hozo-based ontology building experiences. Establishment of a computational model of roles contributes to building good ontologies because such a theory would provide useful guidelines for dealing with view-related and context-dependent distinctions related to roles.
Social acquisition of ontologies from communication processes
Authors: Nickles Matthias
Published: January 2025

This work introduces a formal framework for the social acquisition of ontologies which are constructed dynamically from overhearing the possibly conflicting symbolic interaction of autonomous information sources, and an approach to the pragmatics of communicated ontological axioms. Technically, the framework is based on distributed variants of description logic for the formal contextualization of statements w.r.t. their respective provenance, speaker's attitude, addressees, and subjective degree of confidence. Doing so, our approach demarcates from the dominating more or less informal approaches to context and provenance representation on the semantic web, and carefully distinguishes between communication attitudes such as public assertion and intention exhibited on the (semantic) web on the one hand, and mental attitudes such as private belief on the other. Furthermore, our framework provides formal means for the probabilistic fusion of controversial opinions, and presents a semantics of information publishing acts. Our approach provides an incomplex and genuinely social approach to knowledge acquisition and representation, and is thus expected to be widely applicable in fields such as the semantic web and social software, and possibly also in other distributed environments such as P2P systems.
Detection of multi-size peach in orchard using RGB-D camera combined with an improved DEtection Transformer model
Authors: Yang Yu , Wang Xin , Liu Zhenfang , Huang Min , Sun Shangpeng , Zhu Qibing
Published: January 2025

The first major contribution of the paper is the proposal of using an improved DEtection Transformer network (named R2N-DETR) and Kinect-V2 camera for detecting multiple-size peaches under orchards with varied illumination and fruit occlusion. R2N-DETR model first employed Res2Net-50 to extract a fused low-high level feature map containing fine spatial features and precise semantic information of multi-size peaches from Red-Green-Blue-Depth (RGB-D) images. Second, the encoder-decoder was performed on the feature map to obtain the global context. Finally, all detected objects were detected according to each object’s global context. For the detection of 1101 RGB-D images (imaged from two orchards over three years), the R2N-DETR model achieves an average precision of 0.944 and an average detecting time of 53 ms for each image. The developed system could provide precise visual guidance for robotic picking and contribute to improving yield prediction by providing accurate fruit counting.

Published: January 2025

Summary. Geotechnical monitoring is a system of observation, collection and data analysis on the condition of soils, basements and structural elements of facilities. It is a key tool for safety assurance and control during the reconstruction of structures. This is extremely important while old buildings reconstruction, where unexpected reactions to changes in loads are possible. The monitoring of emergency facilities is especially important, where even minor changes can lead to serious consequences.
Geotechnical monitoring of the Chernihiv`s hospital was conducted. The building was put into operation in 1982. Since 1984, the building began to deform. There were opening of temperature joints with displacement of transverse walls, separation of the longitudinal wall from the transverse ones, minor deformation cracks in other blocks were detected. In the early 1990s, the works for strengthening of the structures was carried out, but they were not fully completed. In 2016, a major repair of the roofing and the drainage system from the building were carried out. The deformation of the building did not stop. In 2018, the SE NIIBK conducted a study and, based on the recommendations of «Eurotechindustry» LLC, a reinforcement of the stairwell was developed. However, in 2022, during active hostilities in the Chernihiv city, the hospital was severely damaged. There were direct hits and the collapse of structure`s elements. The meticulous inspection of the facility in order to establish the residual resource and reliability of the whole structures becomes necessary. An inspection of the hospital building as well as geotechnical monitoring, particularly engineering and geodetic observations, and verification calculations of the basement were performed.
Determination of the deformation modulus of soil-cement by laboratory methods during construction site investigations
Authors: NOVYTSKYI Oleksandr , SKRYPKA Yevhenii
Published: January 2025

Summary. In the modern construction of multi-storey buildings, pile foundations are becoming increasingly common in difficult conditions of weak soils. Modern engineers face the difficult task of choosing design solutions that not only meet modern construction requirements but also ensure economic feasibility in dense urban development and complex geology. One of the most promising methods of solving this problem is the use of soil-cement elements to reinforce the foundation as an alternative to pile foundations. This approach can significantly reduce the cost of constructing foundations and reduce the labor intensity of the processes associated with design and construction due to the simple technology of such elements.
The main purpose of the study is to evaluate the physical and mechanical properties of soil cement produced by the drilling and mixing method, as well as to determine its deformation modulus during the construction of a residential building.
To determine the modulus of deformation of the reinforced base of a multi-storey residential building, data from engineering and geological surveys were obtained. The geological structure of the territory to the explored depth is based on loams, sandy loams and clays. According to the data obtained, the prolific soil properties were revealed at a depth of 7.5 to 8.4 meters.
To achieve this goal, a number of preparatory works were carried out, including the preparation of equipment, in particular the MII-100 device for measuring bending strength with a working range of measurements up to 100 kgf/cm2, as well as the manufacture of prism samples measuring 40x40x160 for laboratory tests. The prepared samples made it possible to implement a full cycle of experimental studies, including strength and deformation tests.
The results obtained allowed us to conclude that the deformation modulus of the base reinforced with soil-cement elements increases by 15 times compared to conventional soils. This is an important argument in favor of using soil cement in weak clay soils.
The study confirms the high efficiency of using soil cement to strengthen foundations with a methodology for checking the deformation modulus during surveys. Particularly noteworthy is the practical significance of the work, which is to increase the reliability and durability of multi-story buildings. This method can be successfully implemented in modern construction, which will reduce material costs, optimize technological processes and improve the performance of buildings and structures.
UN RECORRIDO AL PEQUEÑO MUNDO DE LAS BACTERIAS

Published: January 2025

Las bacterias son organismos unicelulares procariotas que se encuentran en todos los ambientes del planeta, siendo comensales en diferentes huéspedes (humanos y animales). A comparación de los organismos eucariotas poseen una estructura sencilla, pese a que, contienen al menos dos elementos que les ayudan a sobrevivir como la “cápsula” y los “flagelos”, estos últimos les permiten desplazarse de un lado a otro. Además de que, las bacterias pueden convertirse en “patógenas”, es decir, son capaces de causar enfermedades, usualmente gracias a los plásmidos, que al ser elementos móviles pueden transferir fácilmente genes de virulencia implicados en la patogenicidad de las bacterias como la producción de ciertas toxinas, del mismo modo genes de resistencia a determinados antibióticos, mediante el proceso de conjugación, mecanismo importante de la transferencia genética horizontal, que ocurre de bacteria donadora a una receptora, este fenómeno de resistencia representa actualmente un problema de salud pública.
ENFERMEDADES NO TRANSMISIBLES Y EL SEDENTARISMO
Authors: Bernabé Sánchez Daniela Alexandra , Teutli Mellado Karla Marisol
Published: January 2025

Las enfermedades no transmisibles son un problema de salud pública a nivel mundial,  estas enfermedades se consideran crónico degenerativas y se caracterizan por generar secuelas discapacitantes a largo plazo. Algunos ejemplos de estas enfermedades son enfermedades del corazón, sobrepeso, diabetes mellitus y dislipidemias. Estas enfermedades crónico degenerativas están altamente relacionadas con malos hábitos alimenticios, así como elevados niveles de sedentarismo, lo que se reconoce como estilos de vida no saludables. Es necesario favorecer los procesos de Educación para la salud para aumentar la cantidad de actividad física que la población infantil y adulta realiza diariamente. Para la población adulta resulta complicado disminuir las conductas o momentos de inactividad, ya que la mayoría de los trabajos mantienen a sus empleados en las mismas posiciones por periodos de tiempo prolongados, lo que aumenta el riesgo de lesiones del aparato locomotor, esto puede minimizarse si se fomenta un programa de actividad física inicialmente moderado y de bajo impacto, que progrese gradualmente hasta alcanzar una mayor intensidad. Sin embargo, existe evidencia de que el aumento en los niveles de actividad física mejora la morbilidad y mortalidad por estas enfermedades.

Published: January 2025

El estrés es uno de los factores debilitantes más comunes en la actualidad. Es conocido que el sistema dé respuesta al estrés causa modificaciones bioquímicas en la homeostasis del organismo, alterando la comunicación de distintas áreas del sistema nervioso central, como el hipotálamo, con el sistema nervioso periférico. El estrés promueve agotamiento, fatiga, tensión laboral, desequilibrio emocional y condiciones psicosociales adversas, pudiendo desencadenar patologías que incluyen cambios en el metabolismo como depresión, obesidad, modificaciones en la comunicación nerviosa. Así como variaciones en las concentraciones de distintas hormonas como la GnRH, FSH, LH y hormonas esteroides, las cuales están directamente relacionadas con el funcionamiento de los ovarios y la reproducción. Las fluctuaciones fisiológicas causadas por el estrés provocan cambios en el sistema reproductor femenino, causando alteraciones sobre los ciclos reproductivos, la síntesis de hormonas esteroides y la liberación de ovocitos, así como en la gestación y en el desarrollo del embrión.

Se ha descubierto que la combinación plata-zeolita tiene un efecto biocida, que está relacionado con el estado de oxidación de las especies de plata y el tamaño de las partículas, dichas propiedades biocidas ayudan a la inhibición de Staphylococcus aureus, Escherichia coli (E. coli) y Candida albicans (C. albicans). En este trabajo, se estudió el efecto inhibidor de la proliferación de Escherichia coli (E. coli) a diferentes concentraciones de zeolita intercambiadora de plata sobre un sustrato de algodón. La zeolita de intercambio iónico Ag+ se caracterizó mediante microscopía electrónica de barrido (MEB) y difracción de rayos X (DRX); además, se evaluó la eficiencia antibacteriana en el tejido mediante el Método Kirby-Bauer. De acuerdo con los resultados, se aprecia que el material desarrollado a base de zeolita Ag+ tiene el efecto antimicrobiano, toda vez que después de 24 horas de cultivo de la bacteria E. coli sobre el textil, no se aprecia la presencia de dichas bacterias.

En los últimos años, el avance alcanzado en el desarrollo de las aplicaciones biomédicas se ha dado de forma significativa, debido principalmente, al gran esfuerzo que ha tenido la comunidad científica internacional en temas relacionados a la nanociencia y nanotecnología, en especial en el estudio y desarrollo de nanopartículas, las cuales son estructuras que tienen tamaños menores a los 100 nanómetros. Las nanopartículas están conformadas por unos pocos cientos de átomos, lo que genera que sus propiedades sean únicas y cambien considerablemente a nivel macrométrico. Dentro de la familia de materiales nanoestructurados, con propiedades únicas, se encuentran las nanopartículas de carbono, las cuales son muy versátiles debido a que presentan diferentes tipos de estructuras. Esto las convierte en extraordinarias opciones para su uso como transportadores de fármacos, lo cual las hace una prominente opción para su uso en el área oncológica, en especial para los tratamientos contra cáncer. En este trabajo exploramos el fascinante mundo de los nanomateriales, con propiedades excepcionales para la liberación de fármacos. Tales como  las sorprendentes nanoestructuras de carbono, compuestas por nanotubos y grafeno, con resistencia y biocompatibilidad ideales para aplicaciones biomédicas. La importancia principal es que estos avances prometedores anticipan una revolución en el diagnóstico, tratamiento y prevención de enfermedades, lo cual en un futuro puede llegar a redefinir el futuro de la medicina.

La inteligencia artificial (IA) está cambiando el modo de ver la tecnología a nivel mundial. Desde su aplicación en los diversos asistentes de voz hasta su uso en apps en teléfonos celulares, la IA es un tema que está tomando gran relevancia debido a los beneficios que ha mostrado en el avance tecnológico de diversos sectores de la industria y la ciencia. Además, del procesamiento de lenguaje natural, la visión computacional y la robótica, dos de las ramas más relevantes de la IA son el machine learning o aprendizaje automático y el deep learning o aprendizaje profundo. En general, el objetivo común es la predicción de valores u objetos a partir del uso de datos. Estas dos ramas pueden abordar problemas de regresión, clasificación y agrupamiento, es decir, son capaces de predecir variables cuantitativas y cualitativas, así como agruparlas de acuerdo a características similares. Dentro de las variables cuantitativas de interés predictivo en el área de la termodinámica (de manera directa) y de la ingeniería química (como aplicación), están las propiedades termoquímicas, de las cuales una de las que ha destacado por su importancia es la entalpía de combustión. En la actualidad, es posible obtener valores de entalpía de combustión con diferentes técnicas tales como la calorimetría de combustión (técnica experimental), métodos de estimación (técnica semiempírica) y, en la última década, el machine learning (técnica teórica). Siendo esta última la que ha logrado captar el interés en la comunidad científica debido a su impacto en diversas áreas del conocimiento, incluyendo la termodinámica, ya que permite predecir propiedades termoquímicas como la entalpía de combustión de diversos compuestos químicos.

Este artículo aborda la creciente problemática de la resistencia a los antimicrobianos disponibles que algunos patógenos han desarrollado, destacando cómo ciertos comportamientos de la población agravan esta situación en los ambientes acuáticos y terrestres. Así, la resistencia a los antimicrobianos (RAM) se ha convertido en una preocupación global, ya que las bacterias se adaptan y evolucionan para resistir los mecanismos de acción de los medicamentos diseñados para eliminarlas, lo que resulta en tratamientos cada vez menos efectivos y un aumento en la persistencia y propagación de enfermedades infecciosas. La RAM no solo compromete la salud humana, sino también afecta negativamente a los ecosistemas acuáticos y la biodiversidad. Aquí, se destaca el papel de los avances tecnológicos, en particular, el desarrollo de nanomateriales para la degradación de antibióticos como una medida prometedora para combatir la contaminación por estas sustancias y combatir la RAM. Por otra parte, se proponen estrategias para minimizar el impacto ambiental de los fármacos, incluyendo el uso responsable de antibióticos en medicina y veterinaria, mejoras en la gestión de residuos, y el fomento de la investigación y desarrollo de alternativas más sostenibles para el control de patógenos. Finalmente, se enfatiza la necesidad de una acción colectiva y responsable para preservar la eficacia de los antibióticos, proteger la salud pública y asegurar la conservación de los ecosistemas para las futuras generaciones.

Published: January 2025

Background: Effective anesthesia techniques are essential for managing pain and facilitating recovery in surgical procedures involving the lower abdomen and lower limbs. Epidural anesthesia and combined spinal-epidural (CSE) block are commonly used methods, each with distinct advantages and limitations. This study compared the efficacy, safety, and patient satisfaction of epidural anesthesia versus CSE block in lower abdomen and lower limb surgeries.
Methods: A trial was conducted with 100 participants undergoing elective lower abdomen or lower limb surgeries. Participants were assigned randomly to receive either epidural anesthesia or CSE block. Data on demographic characteristics, intraoperative and postoperative pain scores, analgesic consumption, complications, and duration of hospital stay were collected and analyzed using SPSS version 23.0.
Results: The CSE block group had significantly decreased postoperative pain levels at 1, 6, 12, and 24 hours contrasted to the epidural group (p<0.001). Total post-operative analgesic consumption was decreased in the CSE group (p<0.001). The groups had similar hypotension, nausea, and urine retention rates. Although not statistically significant (p=0.09), the CSE group had a shorter mean hospital stay.
Conclusion: The CSE block provides superior postoperative pain relief and reduces the need for additional analgesics compared to epidural anesthesia, without increasing the risk of complications. These findings suggest that CSE block may be a more effective option for managing postoperative pain in lower abdomen and lower limb surgeries.
Recommendations: Larger trials with long-term follow-up are needed to confirm these findings and examine CSE block's benefits in diverse surgical settings.
Keywords: Epidural anesthesia, Combined spinal-epidural block, Lower abdomen surgery, Lower limb surgery, Postoperative pain management.

Introduction: Neglected mandibular fractures can interfere with mastication, swallowing, speech, and facial appearance. Neglected fractures also make treatment procedures difficult. Correct diagnosis and treatment are essential to prevent complications. Case report: A 22-year-old male patient came with a complaint of a fracture of the mandible, which was caused by a traffic accident about three weeks previously and had not been treated. The diagnosis, in this case, was a neglected fracture in the left mandibular parasymphysis region, with clinical symptoms of malocclusion characterized by an edge-to-edge incisor relationship and a cusp-to-cusp relationship of the right posterior teeth. The treatment carried out was ORIF with the installation of 2 titanium plates which had previously been refractured at the fracture line. Conclusion: Neglected mandibular fractures can occur due to slow or inappropriate treatment. In treating neglected fractures, refracturing is necessary to obtain optimal occlusion and function. ORIF treatment, in this case, is the treatment of choice with optimal results and minimal complications
