Published: April 2024

Pese a ser una patología infrecuente, la endocarditis infecciosa sigue siendo un problema importante de salud pública, con una alta morbimortalidad mundial. Aproximadamente un 10% de los casos son un autén-tico reto diagnóstico porque son producidas por microorganismos atípicos que no crecen en los métodos convencionales de cultivo, no presentan los hallazgos típicos en pruebas de imagen y porque se suelen presentar en una forma más avanzada y complicada de la enfermedad. A continuación, presentamos un caso clínico que muestra como puede presentarse una endocarditis infecciosa por Coxiella burnetii, un microorganismo atípico.

Authors: Villanueva Muñoz Omar Ludwing , Vargas Galgani Mario
Published: April 2024

La disyunción de anillo mitral se ha asociado a arritmias en algunos casos severas y al prolapso arrítmico, sin embargo, se detecta en la mayoría de la población de acuerdo a la técnica que se utilice. Existe un problema de definición dado que la mayoría lo considera solo en sístole, demostrándose que es un error y que debe ser visto la diástole para considerar una real disyunción. Es una anormalidad valvular en busca de definición.

Published: April 2024

Las fístulas coronarias congénitas son anomalías vasculares poco comunes. Generalmente son asintomáticas y se diagnostican en el estudio de un soplo cardíaco. El seguimiento clínico y por imagen multimodal es esencial para establecer un manejo adecuado para cada paciente. Presentamos el caso de un varón que lleva 25 de años de seguimiento por múltiples fístulas coronarias con un importante cortocircuito izquierda-izquierda que ha causado una dilatación ventricular izquierda con una fisiopatología similar al de una insuficiencia aórtica severa. El manejo terapéutico dependerá de la evolución clínica y de la factibilidad anatómica para realizar el cierre de los trayectos fistulosos.

Published: April 2024

ᴅ-cycloserine (DCS), an FDA-approved medicine for the treatment of tuberculosis, is also a partial agonist at the glycine recognition site of N-methyl-ᴅ-aspartate (NMDA) receptor and has shown significant treatment efficacy for central nervous system (CNS) disorders including depression, schizophrenia, Alzheimer’s disease, and post-traumatic stress disorder. The physicochemical properties of DCS, however, limit the options of formulation and medicinal applications of DCS, and warrants further investigation for the development of CNS therapeutics. Nanocrystals play an important role in pharmaceutic design and development. The properties of nanocrystals are remarkably different from their bulk material counterpart, attributed to the large surface-area-to-volume ratio which can improve the bioavailability. In this study, for the first time, DCS, a highly water-soluble compound, has formed nanocrystals and this was confirmed by scanning electronic microscopy and X-ray powder diffraction. Furthermore, DCS nanocrystals were applied to several formulations to test their stability and then to the in vitro Franz diffusion test with reservoir patch formulation as well as in vivo pharmacokinetics study with enteric capsules. We tested these formulations regarding their nanocrystal physical properties, size effect, and dissolution rate, respectively. We found that DCS nanocrystals showed good performance in the Franz diffusion test and rodent pharmacokinetic studies due to the nanoparticle size and faster dissolution as compared with the commercial DCS powder. These DCS nanocrystal formulations could offer a new approach for the development of an advanced drug delivery system for the treatment of CNS disorders.

EVALUATION OF DYNAMIC AND STATIC MODULI OF ELASTICITY OF HYBRID EUCALYPTUS WOOD FROM DIFFERENT LOCATIONS IN GHANA
Authors: SEIDU HARUNA , BROUGUI MARWA , ABDUL RAHIM NOOR ROZIANA , NÉMETH RÓBERT
Published: April 2024

This study explores the mechanical properties of hybrid eucalyptus wood, with a focus on dynamic and static moduli of elasticity (MOE), which is crucial for understanding the stiffness behaviour of wood. The research employs acoustic and static measurements on samples prepared from six trees sourced from Winneba and Amantia in Ghana. The results reveal significant variations in static and dynamic MOE, with higher static MOE observed in both Amantia and Winneba samples. However, Winneba and Amantia samples at the tree level were found to be insignificant statistically. The densities of the samples from the two locations, Winneba and Amantia, were found to be significantly different. Correlation studies revealed strong relationships between wood density and static MOE, as well as static and dynamic MOE, providing valuable insights into the comprehensive characterization of the eucalyptus globulus species grown in Ghana.

Published: April 2024

The Amazon rainforest displays wide ecological diversity, reflected in its wood variation. The study evaluated the influence of different locations on the properties of wood from native tropical species extracted from the Brazilian Amazon. The most frequent species in the locations were selected, and a total of 104 trees were extracted. The logs were sawed breakdown to make beams (50 × 110 × 2,000 mm). The wood density and mechanical resistance of these samples were determined. The wood density ranged of 0.25-1.00 g/cm3, modulus of elasticity and rupture in static bending ranged of 5,982-19,025 MPa and 35-204 MPa, respectively. For compressive strength parallel to the grain, the range was 24-111 MPa; the strength of wood compressed parallel was 20-245 MPa, and the shear strength was 50-245 MPa. The study detected differences in the physical and mechanical properties of the woods regarding the origin of the sites (Amazonas-Pará/Brazil), with the modulus of elasticity and the wood density showing the greatest variations.

Evaluación Formativa En Matemáticas: Una Propuesta Para El Desarrollo De Competencias Evaluativas En Docentes De Instituciones Públicas En Colombia
Authors: Camargo Arias Jesús Antonio , Canabal Guzmán Javier Darío
Published: April 2024

El presente articulo tiene la intención de publicar un resumen sobre los avances investigativos (específicamente del marco contextual, teórico y metodológico) para el desarrollo de una propuesta orientada al diseño de un programa de formación docente que contribuya con la adquisición teórica de mecanismos de aplicación del proceso de la evaluación formativa en el marco de la educación por competencias para el área de Matemáticas. La idea surge a partir de la necesidad de aplicar de cara al futuro un enfoque evaluativo que permita simultáneamente desarrollar competencias (que  por cierto actualmente no se están  en un nivel  deseado, así se puede establecer a partir de los resultados obtenidos en las competencias evaluadas en las pruebas aplicadas por el estado), para así de esta manera   valorar el progreso de los estudiantes, pero redireccionando   permanentemente los procesos de enseñanza y de aprendizaje como resultado de una reflexión continua sobre la praxis educativa.  Para ello se proponen   una serie  de fases  en  la ejecución del proceso  investigativo que den inicialmente la posibilidad    de caracterizar las debilidades y fortalezas del procesos  evaluativo  que se viene desarrollando en las instituciones  educativas públicas de la ciudad, desde la perspectiva de los estudiantes, docentes e instituciones (los tres se constituyen como las unidades de estudio de la población), para luego así construir la propuesta formativa dirigida  a docentes. En ese orden de ideas se opta por aplicar en la metodología la  perspectiva de la comprensión holística,  ya que  esta permite articular  de manera coherente   y simultánea   diversos  epistemes, métodos,  herramientas de recolección  y  análisis de información;  que de otra forma  no sería posible desarrollar, considerando  la reducción epistémica que se da al  escoger  un solo enfoque. Seguidamente se propone implementar como método de investigación el holopráxico y se eligen como herramientas de recolección de información (luego de la previa determinación de las categorías apriorísticas) la encuesta, entrevista semiestructurada, observación directa y la revisión documental.

John Adams – Intellektueller, Antiintellektueller, Nichtintellektueller?
Authors: Steffensen Nils
Published: April 2024

Für Richard Hofstadter war die Frühe Republik die Epoche der Intellektuellen schlechthin. Zu ihren markantesten Exponenten zählte John Adams. Weithin gilt er als ein einseitig auf die Geschichte und Politik fixierter
Theoretiker mit überspannten Ansichten, ohne tieferes Interesse an anderen Wissenschaften oder den Künsten: ein Außenseiter in der aufgeklärten kolonialen Gesellschaft Neuenglands. Dieser Beitrag untersucht das intellektuelle
Profil des zweiten Präsidenten der Vereinigten Staaten näher. Er zeigt, dass sich in Adams eine Professionalisierung der Wissenschaft manifestiert, die über die Praxis von »gentleman scholars« hinaus auf das 19. Jahrhundert
weist. Er demonstriert, dass Adams’ auf Nutzen fokussiertes Bildungs- und Wissenschaftsverständnis sich in den Bahnen der Aufklärung bewegte und von Adams selbst mit den Anforderungen der historischen Situation, der
Gründungsphase der USA, begründet wurde. Er belegt, dass Adams mitnichten Verachtung für die Künste hegte, sondern dass eine solche Sichtweise aus der häufig dekontextualisierten Interpretation einschlägiger Äußerungen
herrührt. Auf der Basis dieser historischen Untersuchung prüft der Beitrag die Triftigkeit von Hofstadters Rekonstruktion der Frühen Republik, aber auch die Tragweite seines Begriffs des Intellektuellen.
Weiß, männlich, gebildet

Published: April 2024

Der Beitrag widmet sich dem New Orleanser Deutschamerikaner J. Hanno Deiler, in dessen Handeln und Intellektualismus, so die These, maßgeblich die »un/sichtbaren Normen« des Weißseins, Männlichseins und Gebildsein eingeschrieben waren und sich mit westlich-aufklärerischen) bildungselitären Normativitäten und Hegemonialitäten verschränkten. Der Beitrag folgt dementsprechend den Spuren des Gelehrten, Musikers und Pädagogen Deiler und legt so die »un/sichtbaren Normen« eines intellektuellen Weißseins offen. Auf diesem Wege werden nicht nur die Überlegungen Richard Hofstadters zum Anti-/Intellektualismus in der amerikanischen Geschichte einer Prüfung unterzogen, vielmehr lassen sich auch die jüngsten Forschungen von Historiker:innen wie Heike Bungert (2017) ergänzen und die Perspektive auf die deutschamerikanischen Akteure des späten 19. Jahrhunderts weiter differenzieren.
Vom »Common Sense« zu den »Alternative Facts«
Authors: Lütjen Torben
Published: April 2024

Die Zeit nach 1945 in den Fokus nehmend erkundet der Beitrag die Metamorphosen des U.S.-Antiintellektualismus der letzten Jahrzehnte und identifiziert drei Typen des konservativen Antiintellektualismus: Erstens eine
romantische und antirationalistische Geisteshaltung, einen Common-Sense-Antiintellektualismus, bei dem es im Kern um die Verteidigung von Intuition, Erfahrung, Bauchgefühl und Pragmatismus gegen abstraktes Theoretisieren geht.
Zweitens eine Form des postmodernen Antiintellektualismus, bei dem abstraktes Wissen nicht per se abgelehnt, aber stets als relativ herabgestuft und behauptet wird, die eine Wahrheit gebe es überhaupt nicht. Drittens einen
Antiintellektualismus, der als alternative Wissenschaft oder als Simulation von Wissenschaft daherkommt.
Capitals of Siberian Autonomous Regions – the Mission of Nation-building (Dynamics of Functions, Status and Ethnization of Urban Space)
Authors:   Irkutsk State University, Dyatlov Viktor ,   National Research Tomsk State University
Published: April 2024

The implementation of the Soviet nation-building project assumed the decisive role of cities in the formation of nations - an urban product by definition. Within the framework of the ideology of institutionalization of ethnicity, they were appointed capitals of the created national autonomies and were endowed with the appropriate mission and resources. For the emerging or prearranged nations of Siberia those were either Russian cities in terms of population or new cities grown for this purpose on the basis of Russian villages. The rooting policy a tool for cultivating a titular cultural and political elite in them, building an urban infrastructure adequate to the status of the national capital. In the process of implementing this mission, cities with a special culture of relationships have been formed, with a greater regulating role of ethnicity than in ordinary capital cities. The general genesis predetermined the similarity of the capitals of the Siberian autonomous regions considered in the article - Ulan-Ude, Kyzyl, Abakan, Gorno-Altaisk. No less clearly visible are the differences that demonstrate the different results of the implementation of the standard national program. The reasons for these differences were starting resources (the presence of a city and an urban tradition, a European-educated titular elite with experience in political and cultural mobilization), a demographic factor, and a different role in national modernization development.
The Roads of the Sayan Mountains: Theorizing Remoteness in Eastern Siberia
Authors:   George Washington University, Kuklina Vera ,   V. B. Sochava Institute of Geography, Siberian Branch of Russian Academy of Sciences, Holland Edward ,   University of Arkansas
Published: April 2024

This article is an authorized translation from English of the original article, first published in: Geoforum 2018, issue 88, pp. 36-44. The Sayan crossroads is a distinct cultural and economic region in the mountains of eastern Siberia. It spans three federal units in the Russian Federation: the national republics of Tyva (Todzha kozhuun) and Buryatia (Okinskii raion), as well as Irkutsk oblast (Tofalarskoe municipality). Attempts at integration by the state during the Soviet period and afterwards have privileged the construction of roads in a variety of forms to connect these areas economically with regional centers and, in turn, the rest of the country. Yet this process has been uneven and led to divergences in the economic regimes in each of the three regions that make up the crossroads. The evolution of subsistence economies, exploitation by extractive industries, and the development of tourism as an alternative source of income all differ across the three federal subunits. In turn, these divergences within the crossroads as a region point to variation in the condition of remoteness. Remoteness is an instance of relative immobility, determined by physical geography, environment, and ethnicity. And remoteness influences the function that roads play in integrating state spaces both economically and politically. In turn, this article argues for the foregrounding of the remote in the literature on mobilities in human geography, considering what the condition of remoteness allows for and forecloses in the articulation of state power and the integration of hard to-reach areas.

Poco se sabe sobre el grado de integración de los mercados ﬁnancieros a nivel regional en la UE. Este artículo proporciona un primer vistazo a los ﬂujos de préstamos interregionales dentro de Europa. Partiendo de la base de datos «Loan Level Initiative» lanzada por el BCE, que permite acceder a información de más de 35 millones de préstamos activos, construimos un conjunto de datos georreferenciados de préstamos titulizados, capaz de cubrir el periodo 2014-2018 y las 166 regiones europeas NUTS 2 para las que dichos datos existen. Tras depurar y explorar el conjunto de datos, en este artículo exploramos su dimensión geográﬁca, mediante un análisis gráﬁco y econométrico centrados en explicar la demanda regional de dichos préstamos, utilizando variables geográﬁcas y socio-económicas, y empleando diferentes especiﬁcaciones de datos de panel, clásicos y con elementos de econometría espacial.
Dynamic interaction between permanent and temporary employment across manufacturing labor markets in the Mexican states: A structural panel VAR approach
Authors: Torres Preciado Víctor Hugo , Mejía Reyes Pablo
Published: April 2024

México’s implementation of several labor market reforms aimed to stimulate the ﬂexibilization of labor relationships have brought long-standing concerns among scholars and governmental authorities about a displacement process of permanent by temporary jobs. In this regard, this manuscript aims to respond whether the dynamic interaction between permanent and temporary employment across Mexican states describe a substitution or complementary relationship. By means of implementing a structural panel vector autoregressive model, our estimation results demonstrate that a combination of both types of interaction, substitutive and complementary ones, prevail across manufacturing labor markets at state level. Moreover, a marked heterogeneity among estimated dynamic responses suggests that incentivizing permanent employment would induce stronger substitution eﬀects on its temporary counterpart than, for example, substitution of permanent job positions arising when incentivizing temporary employment.

A new species of Larca is described from dry habitats in a cave in central Colorado. Like other cave-dwelling species of Larca, the new species Larca bouldericasp. nov., shows relatively modest morphological adaptations, such as pale colouration and slightly elongated appendages, compared with their epigean counterparts. This species is the sixth cave-dwelling species of Larca described from North America and, like other cave-dwelling Larca in North America and Europe, tends to be distributed in more southerly regions.
Emotional intelligence protects nurses against quiet quitting, turnover intention, and job burnout
Authors: Galanis Petros , Katsiroumpa Aglaia , Moisoglou Ioannis , Kalogeropoulou Maria , Gallos Parisis , Vraka Irene
Published: April 2024

Background

Emotional intelligence can improve nurses' interpersonal and coping skills, job performance, and resilience. However, there is a dearth in the literature on whether emotional intelligence affects levels of quiet quitting, turnover intention, and job burnout in nurses.

Objective

We examined the relationship between emotional intelligence, quiet quitting, turnover intention, and job burnout.

Methods

We conducted a cross-sectional study in Greece with a convenience sample of 992 nurses. We used the following valid tools to measure our study variables: the Trait Emotional Intelligence Questionnaire-Short Form, the Quiet Quitting Scale, and the single item burnout measure.

Results

The mean age of our nurses was 42.2 years. After controlling for gender, age, work experience, shift work, and understaffed department, the multivariable linear regression models indicated significant negative relationships between emotional intelligence and quiet quitting, turnover intention, and job burnout. Specifically, self-control reduced detachment, lack of motivation, job burnout, and turnover intention. Moreover, emotionality reduced detachment, lack of motivation, and lack of initiative. Sociability reduced lack of initiative and lack of motivation, while well-being reduced lack of motivation, job burnout, and turnover intention.

Conclusion

Emotional intelligence reduced quiet quitting, turnover intention, and job burnout in nurses. Therefore, nurse managers and policy-makers should apply interventions to optimize the emotional intelligence profiles of nurses.
Locally robust inference for non‐Gaussian SVAR models
Authors: Hoesch Lukas , Lee Adam , Mesters Geert
Published: April 2024

All parameters in structural vector autoregressive (SVAR) models are locally identified when the structural shocks are independent and follow non‐Gaussian distributions. Unfortunately, standard inference methods that exploit such features of the data for identification fail to yield correct coverage for structural functions of the model parameters when deviations from Gaussianity are small. To this extent, we propose a locally robust semiparametric approach to conduct hypothesis tests and construct confidence sets for structural functions in SVAR models. The methodology fully exploits non‐Gaussianity when it is present, but yields correct size/coverage for local‐to‐Gaussian densities. Empirically, we revisit two macroeconomic SVAR studies where we document mixed results. For the oil price model of Kilian and Murphy (2012), we find that non‐Gaussianity can robustly identify reasonable confidence sets, whereas for the labor supply–demand model of Baumeister and Hamilton (2015) this is not the case. Moreover, these exercises highlight the importance of using weak identification robust methods to assess estimation uncertainty when using non‐Gaussianity for identification.
Adapter Racine à l’opéra

En 1786, la Phèdre de Racine est adaptée en tragédie lyrique par le compositeur Jean-Baptiste Lemoyne et le librettiste François-Benoît Hoffman pour l’Académie royale de musique de Paris. À partir d’un dossier génétique riche et diversifié (partitions, livret, témoignages de contemporains, extraits de correspondance), l’article se propose d’étudier le contexte et les conditions de cette adaptation. Outre une meilleure compréhension de la circulation et de l’influence du corpus racinien sur la scène d’opéra, étudier la Phèdre de Lemoyne et Hoffman dans une perspective génétique permet de mettre en évidence les enjeux propres à l’étude génétique du spectacle vivant, en tenant compte du contexte de création, des conditions de production et de la dimension nécessairement collective d’une œuvre en constante évolution.

Alain Tanner s’est souvent positionné contre le primat du récit et l’adaptation littéraire, affirmant privilégier la spontanéité d’une mise en scène « sur les lieux ». Cet article aborde la genèse de son film Light Years Away (1981), adapté du roman La Voie sauvage de Daniel Odier, en structurant son analyse autour de la problématique de la représentation de l’espace. L’approche génétique, envisageable grâce au fonds Alain Tanner déposé à la Cinémathèque suisse, invite d’une part à nuancer le discours d’un réalisateur valorisant la singularité de son œuvre et de son regard d’auteur. D’autre part, elle permet d’interroger le processus d’adaptation à l’écran de l’espace diégétique du roman, construit autour d’un ailleurs marginal et non localisé, tandis que les fictions de Tanner étaient jusqu’ici toujours ancrées en Suisse romande. La notion foucaldienne d’hétérotopie devient alors pertinente pour penser l’organisation spatiale du récit et son évolution à travers les étapes de sa genèse.
A critical analysis of Caixa's digital social savings account from the perspective of coproduction
Authors: Vieira Aline Vasconcelos , Júnior Noel Torres
Published: April 2024

The COVID-19 Pandemic led many service providers to carry out innovations in their processes. These innovations enabled the creation of new services intending to increase their efficiency and responsiveness. In this context, the Caixa launched the digital social savings account for the payment of emergency aid that enabled broad and fast access of this product to its beneficiaries. This new service demanded a more active role from its users, who became co-producers in this process. The coproduction of this service was critically analyzed using the Process-Chain-Network Method (PCN). This study identified some difficulties in implementing this service that denoted a lack of implementation of recommended literature strategies. Furthermore, some challenges to the adoption of coproduction in this sector were identified.
Co-producing virtual consumption extraordinary experiences: a netnography of Brazilian NBA fans

Published: April 2024

The concept of extraordinary experience in the consumer culture tradition it is a seminal theme since 1980. Over the last few decades, discussions have advanced to incorporate virtual ambiance, prosumption abilities, and interaction between peers. Likewise, the consumption of sports leagues has been reframed based on these three emerging themes. Thus, the present study seeks to understand the consumption extraordinary experiences of Brazilian NBA fans through their virtual interactions. To this end, a netnography was carried out between 2018 and 2020 on Twitter. The results point to the overlapping media and sports aspects that allow Brazilian fans of the league to experience liberating or stochastic moments and produce their performances or live adventures with NBA broadcasts. Consequently, such findings endorse the ability of sports league fans to prosume extraordinary experiences aligned with elements that reflect sports business management efforts.
La prensa y opinión públicas chilenas frente a las negociaciones del “enfoque fresco” con Bolivia
Authors: Cortés Díaz Milton
Published: April 2024

Entre 1986 y 1987, los gobiernos de Chile y Bolivia desarrollaron conversaciones respecto a la aspiración marítima boliviana. En estas negociaciones, que se conocieron como el “enfoque fresco”, Bolivia propuso que Chile le cediese un corredor al norte de Arica o un enclave. A cambio, Bolivia ofrecería compensaciones no territoriales, principalmente el uso de las aguas del altiplano. En este trabajo buscamos las razones del fracaso de esta negociación, la última en la cual Chile aceptó discutir una transferencia territorial,  en el que postulamos jugó un rol clave la reacción de la opinión pública.
Litio y desarrollo en Argentina: los desafíos del sistema de gobernanza multinivel y el vínculo con China
Authors: Juste Stella , Rubiolo Florencia
Published: April 2024

A partir del análisis de la industria del litio en Argentina, el argumento de este trabajo es que el accionar externo de las provincias del noroeste argentino (Jujuy, Salta y Catamarca) contribuyó a instrumentalizar parte de la política exterior hacia China; sin embargo, esa vinculación creó focos de tensión con el Estado Federal en torno al modelo a implementar para el desarrollo del litio y a la relación con el país asiático. Entendemos que el vínculo con China, que tiene una naturaleza complementaria e incremental, evidencia tensiones preexistentes del sistema federal y las limitaciones para la coordinación e implementación de una estrategia nacional de vinculación internacional de Argentina en torno al mineral, así como la definición de una estrategia nacional de desarrollo para la industria del litio. A través de un enfoque cualitativo, abordamos las condiciones externas que impactan en la industria del litio en la región y en Argentina en particular, y cómo la ausencia de un modelo nacional de desarrollo de la industria del litio promueve una inserción basada en la explotación y exportación a grandes socios externos en base a un patrón primario

El presente trabajo examina la cooperación multilateral entre gobiernos locales y organismos internacionales relacionada con el apoyo a las personas migrantes en proceso de regularización, desde la mirada de actores político-administrativos en los municipios fronterizos de Chiapas, México. En particular, se enfoca en cómo las cooperaciones y sus objetivos se materializan y en qué forma inciden en el diseño, la organización y la operación de programas de apoyo, con un énfasis en las prácticas administrativas de los burócratas locales. La metodología empleada se sostiene en, principalmente, entrevistas con personas clave, conversaciones personales y observación participante. El argumento central es que esas cooperaciones multilaterales y programas, conforme descienden a las prácticas, se desarrollan a un nivel personal distintivo, derivando más en acuerdos contextualizados por las dinámicas locales y subjetividades de los actores involucrados que en ámbitos ajustados a estrategias institucionales. La reflexión del presente trabajo no resulta de un análisis deductivo de legislaciones migratorias, sino de una mirada de la práctica burocrática como producto cultural, que analiza la forma en que se traslapan estructuras de poder instrumentalizadas e ideas globales sobre la migración por intereses y subjetividades en el escenario local.

BACKGROUND:

Despite the decline of the COVID-19 pandemic, there continues to be a persistent requirement for reliable testing methods that can be adapted to future outbreaks and areas with limited resources. While the standard approach of using reverse transcription-polymerase chain reaction (RT-PCR) with Taq polymerase is effective, it faces challenges such as limited access to high-quality enzymes and the presence of bacterial DNA contamination in commercial kits, which can impact the accuracy of test results.

METHODS:

This study investigates the production of recombinant Taq polymerase in yeast cells and assesses its crude lysate in a multiplex RT-PCR assay for detecting the SARS-CoV-2 RNA-dependent RNA polymerase (RdRP) and N genes, with human Ribonuclease P serving as an internal control.

RESULTS:

The unpurified yeast Taq polymerase demonstrates sensitivity comparable to commercially purified bacterial Taq polymerase and unpurified bacterial counterparts in detecting the RdRP and N genes. It exhibits the highest specificity, with 100% accuracy, for the N gene. The specificity for the RdRP gene closely aligns with that of commercially purified bacterial Taq polymerase and unpurified bacterial Taq polymerase.

CONCLUSIONS:

The use of unpurified recombinant yeast Taq polymerase shows promise as a cost-effective approach for conducting in-house COVID-19 RT-PCR testing. By eliminating the need for chromatography purification steps, the production of RT-PCR kits can be streamlined, potentially improving accessibility and scalability, especially in resource-limited settings and future pandemics.

Background

Type 2 diabetes mellitus is a major medical condition that constitutes a significant financial burden on most healthcare systems.

Objective

The current research aimed to evaluate the antidiabetic, anti-inflammatory, and antihyperlipidemic effects of 500 mg metformin twice daily for 6 months on various adipocytokines in type 2 diabetes mellitus patients.

Patients and methods

The participants in this study were divided into three groups: the control, the untreated diabetic, and the metformin-treated diabetic groups.

Results and conclusion

Metformin treatment significantly improved the poor oral glucose tolerance and the lowered serum levels of insulin and C-peptide with subsequent better homeostatic model assessment for insulin resistance and sensitivity and β-cell function results. Moreover, metformin treatment significantly decreased the elevated serum levels of glycosylated hemoglobin, high, low, and very low-density lipoproteins, adipokines (visfatin and resistin), and retinol-binding protein-4 expression, with a significant increase in total cholesterol and triglycerides. Metformin also reduced the proinflammatory cytokine expressions (interleukin-1β, interferon-γ, and tumor-necrosis factor-α). In conclusion, metformin can alleviate adipocytokines through anti-inflammatory effects, synergizing with its antidiabetic actions.

Published: April 2024

Background

The accelerated aging caused by reactive oxygen species is a major concern to many people. Antioxidants present in natural products like rice bran oil (RBO) absorb and neutralize free radicals, improving skin appearance and slowing the aging process. However, RBO has limited use on the skin due to greasy sensation, oxidation, and low penetration.

Objective

This study aimed to develop a RBO nanoemulgel and evaluate its anti-aging effects on volunteer skin.

Patients and methods

Nanoemulsion optimized using Box–Behnken design to optimize RBO (x1), surfactant (x2), and cosurfactant (x3) factors towards transmittance response. Nanoemulsion prepared using high-pressure homogenizer and ultrasonication methods.

Results and conclusion

The optimal formula contained 2% oil, 14.732% tween 80, and 1.227% span 80, with characterization of 96.6% transmittance, particle size of 17.8±0.1 nm, polydispersity index of 0.51±0.00, zeta potential of −3.56±0.70, and pH of 6.19±0.05. The optimal formula was further incorporated with CMC-Na base and evaluated it anti-aging effects on upper arm skin volunteer. After 4 weeks of RBO nanoemulgel usage, there was a significant increase on oil content and elasticity parameters on skin volunteers, but not on moisture content. This study highlights the potential of the optimized nanoemulgel formula as an anti-aging solution, addressing signs of aging.

Published: April 2024

Introduction:

Accredited Social Health Activist (ASHA) workers and their activities are regarded as a critical component linking the community and health-care facilities. They are the cornerstone of the Indian public health-care system responsible for spreading awareness and recommending preventive measures in the community. This study aims to assess the awareness, writing skills, and practical-based performance of the ASHA workers in urban and rural Karnataka.

Materials and Methods:

A cross-sectional study was conducted among ASHA workers in rural and urban Mysore district. A multistage sampling technique was adopted for selecting the participants. The ASHA workers were asked to fill out a pretested semi-structured questionnaire. An unpaired t-test was used for inferential statistics. P < 0.05 was considered statistically significant.

Results:

The mean age of the workers in urban areas was 36.38 ± 5.877 years, while in rural, it was 41.53 ± 6.755 years. The overall average score for rural ASHA workers was more (70.49 ± 14.018) when compared to the urban ASHAs (65 ± 13.400). The average years of experience were 6.14 ± 1.44 years in urban and 10.5 ± 2.66 years in rural areas. The daily working hours ranged from 3 to 10 h in urban and 2 to 10 h among rural ASHA workers.

Conclusion:

The overall score of rural ASHA workers was higher when compared to urban ASHAs. Even though the grading and performance of the ASHA workers were good, their expertise in identifying and tackling life-threatening conditions remains inadequate. This can be improved with more vigilant and periodic training and monitoring along with periodic recruitment at regular intervals.

Published: April 2024

Background:

Colonoscopy is the endoscopic examination of the large bowel and the distal part of the small bowel with a CCD camera or a fiber-optic camera on a flexible tube passed through the anus. It can provide a visual diagnosis.

Methods:

In this study, clemastine plus fentanyl was compared with fentanyl plus midazolam in analgesia during colonoscopy. Patients were monitored for pain and hemodynamic changes. The mean age in the group treated with clemastine was 52 years and in the group treated with midazolam was 54 years. There were 56 males and 35 females in the study. There was no significant difference in gender in the two groups. Systolic blood pressure was 109.9 mmHg before and 109.35 mmHg after clemastine administration, which showed no significant difference.

Results:

Diastolic blood pressure was 72.2 mmHg before and 73.7 mmHg after clemastine administration, which showed no significant difference. No change in mean pulse rate (PR) was seen (84/min before and after clemastine administration). In the group receiving midazolam, systolic and diastolic blood pressure changes were not significant, but changes in PR and arterial oxygen saturation were significantly different. Meanwhile, the two groups had a significant lower pain level after colonoscopy in the group receiving clemastine compared to midazolam.

Conclusion:

Based on the results of the present study, clemastine can be used as a main drug for sedation during colonoscopy.
Assessment of Physical Fitness among School Children Aged between 11 and 14 Years in Surat City: A Cross-sectional Evaluation
Authors: Shah Salvi , Diwan Shraddha
Published: April 2024

Background and Purpose:

Physical fitness (PF) is a powerful health indicator in children. The study aimed to measure PF and to evaluate age and gender differences in PF in school children of Surat city aged between 11 and 14 years.

Methodology:

The tests adopted from the EUROFIT Fitness Test Battery were used to measure the components of PF among 872 school children. Initially, body composition (height and weight) of children was measured, and body mass index (BMI) was noted. A 20-m shuttle run test to assess cardiorespiratory fitness, a hand-grip strength test to assess the strength of the hand muscles, a standing broad jump test to assess lower body explosive power, sit-ups in 30 s to evaluate abdominal muscular endurance, a sit-and-reach (SAR) test to assess flexibility, and a 10 × 5 m shuttle test to assess agility/speed were used.

Results:

Overall, boys performed better than girls for all the PF components except for the flexibility (SAR test), in which girls performed better. As the age increases, there would be an increase in body composition (BMI) along with increased performance on different PF components except VO2 max of 20-m shuttle run test.

Conclusion:

The present study concluded that a lower level of PF was noted among school children in comparison to the results of international studies, and girls are less physically fit than boys.
