Authors: Otterness Karalynn , Singer Adam J. , Thode Jr Henry C. , Peacock W. Frank
Published: January 2023

Objective Hyponatremia and hypernatremia are common electrolyte disorders. Few studies to date have focused on patients presenting to the emergency department (ED) with sodium (Na) disorders. Our objective was to determine the incidence and outcomes of hyponatremia and hypernatremia in ED patients.Methods This study was a retrospective, single-center review of electronic medical records at an academic suburban ED with approximately 100,000 annual visits. Subjects included consecutive adult ED patients with Na levels measured while in the ED in 2019. Demographic, clinical, and laboratory data were recorded. Outcomes data, including hospital admission, intensive care unit (ICU) admission, mortality, and length of stay (LOS), were recorded. The primary outcome was inhospital death. Secondary outcomes were hospital admission, ICU admission, ED LOS, and hospital LOS. Univariable and multivariable linear and logistic regression analyses were performed to explore the association of candidate predictor variables and outcomes.Results Na was measured in 57,427 adults (54%) among a total of 106,764 assessed ED visits in 2019. The mean±standard deviation age was 54±21 years, and 47% of participants were male. Mild, moderate, and severe hyponatremia and hypernatremia occurred in 8%, 2%, and 0.1% of patients and 1%, 0.2%, and <0.1% of patients, respectively. Hospital and ICU admission and mortality rates increased as Na levels increased or decreased further from normal. Adjusted odds ratio (95% confidence interval) values for hospital mortality were 2.39 (1.97–2.90) for mild hyponatremia, 3.93 (2.95–5.24) for moderate hyponatremia, 6.98 (2.87–16.40) for severe hyponatremia, 3.65 (2.47–5.40) for mild hypernatremia, 8.58 (4.92–14.94) for moderate hypernatremia, and 55.75 (11.37–273.30) for severe hypernatremia. Hypernatremia was associated with a greater risk of death than hyponatremia. Patients with hyponatremia and hypernatremia had increased LOS times compared to those with normal Na levels.Conclusion Hyponatremia and hypernatremia were associated with greater rates of hospital admission, ICU admission, mortality, and prolonged hospital LOS times.
Post-acute sequelae of SARS-CoV-2 syndrome presenting as postural orthostatic tachycardia syndrome
Authors: Diekman Sarah , Chung Tae
Published: January 2023

The novel SARS-CoV-2 emerged in 2019, and the global COVID-19 pandemic continues into 2022. It has been known that a subset of patients develops chronic, debilitating symptoms after otherwise complete recovery from acute infection of COVID-19. Multiple terms have been used to describe this constellation of symptoms, including long COVID, long-haul COVID, and postacute sequelae of SARS-CoV-2 syndrome (PASC). PASC is broadly defined as a wide range of new, returning, or ongoing symptoms at least four weeks after infection. Those patients are often seen in emergency departments after acute COVID-19 infection, but their symptoms are not adequately managed because the underlying pathophysiology of PASC is not well understood. Among patients with PASC, postural orthostatic tachycardic syndrome (POTS) has been increasingly recognized. POTS is one of the most common forms of autonomic dysfunction and defined by a sustained orthostatic tachycardia during active standing or head-up tilt test in the absence of orthostatic hypotension or other cardiopulmonary diseases. Because POTS is a treatable condition, it is important to recognize POTS among PASC patients. Herein, we reviewed the current literature on POTS and dysautonomia in PASC in order to better understand the overlap and distinction between these pathologies.
Beer, Drugs and Meat
Authors: Jennings Justin , Alaica Aleksa K. , Biwer Matthew E.
Published: January 2023

Feasts were integral to pre-Columbian political economies in the Andes. The large feasts of the Inca Empire, which institutionalized asymmetrical relationships between subjects and the state, are the best known, and a point of comparison for many pre-Inca societies. It is therefore unsurprising that the feasts hosted by the Wari, an expansionist state in the central highland of Peru some 700 years earlier, are often assumed to have played a similar role. In this article, we argue that there were substantial differences between early Wari and Inca practices that reflect the different objectives of their hosts. The large feasts in Inca plazas emphasized the unbridgeable gap between ruler and subjects, while early Wari hosts strove to build interpersonal relationships between households in far more intimate affairs. To better understand the nature of Wari feasting, we discuss the acquisition, preparation, consumption and disposal of roasted camelid meat and hallucinogen-laced beer that were featured at the feasts of the Wari-affiliated settlement of Quilcapampa. The differences in feasting practices may relate to profound differences between early Wari and Inca statecraft that would narrow in Wari’s final century, as the state matured.
Beer and Feasts in the Gamo Highlands of Southern Ethiopia
Authors: Arthur John W.
Published: January 2023

Feasting and the drinking of beer by the Gamo Boreda, who live in the highlands of southern Ethiopia, represent status and seniority and have a long tradition of connecting the living with their ancestors. This paper focuses on the archaeological site of Ochollo Mulato (AD 1270–1950), incorporating oral traditions in association with ceramic ethnoarchaeological and archaeological research documenting the importance of beer and feasting to the Gamo Boreda. Elders recount, from their oral tradition, that Ochollo Mulato is the oldest and most senior of the nine original settlements encompassing the Gamo highlands. Oral tradition and archaeological and ethnoarchaeological ceramic analyses suggest that large-scale ritual feasting of beer and other foods were part of the activities that occurred at Ochollo Mulato over the last eight centuries.

The Nystad Congress and the Release of Russian Prisoners of War in 1721
Authors: Henriksson Håkan
Published: January 2023

After the Nystad Treaty had been signed on 30 August 1721 the work started to implement the articles of the treaty. Article 14 stipulated that the POWs from both sides should be released. The Swedish authorities soon put the wheels in motion to get rid of all the Russian POWs before the winter. The POWs were lodged in towns almost all over Sweden. It was first thought that the number of Russian POWs could still be as many as 1700. However, the real figure was closer to 1200, but throughout the Great Northern War, more than 4000 Russian POWs had been brought to Sweden.By early November almost all Russian POWs had reached the vicinity of Stockholm, and they were ordered to march to the seaport at Vaxholm. The POWs, whose number by that time had reached about 1140 men, were in late November 1721 transported on five hired ships from Vaxholm to Reval. The POWs who had not managed to reach Vaxholm in time for the transport in 1721 were gathered in Uppsala during the winter, and in late April 1722, 60 Russian POWs could leave Vaxholm on two Swedish galleys with Åbo in Finland as the destination.

IMPACT OF NANOSTRUCTURE TYPES AND THIN FILM THICKNESS ON THE PHOTOCATALYTIC PERFORMANCE OF TiO2/V2O5 COMPOSITE COATINGS
Authors: Aimbetova Indira O. , Kuzmin Andrey , Aimbetova Elmira O. , Baigenzhenov Omirserik
Published: January 2023

Titanium dioxide is a very promising compound for various applications. One of the important areas of applicability is photocatalysis. The wide bandgap of the titanium dioxide limits its photocatalytic activity by the utilization of the ultraviolet area of the irradiation, which is ~ 3%. Expanding the area to visible light spectra is possible by doping titanium dioxide with metals and their oxides. Vanadium pentoxide is one of the widespread dopants that allows the narrowing of the bandgap and improves the efficiency of titanium dioxide-based photoanodes. Research into the area of the improvement of titanium dioxide photocatalytic performance with the help of vanadium pentoxide is widespread and in high demand. In this research, for the first time, the effect of vanadium pentoxide thin film thickness on the photoanode based on titanium dioxide nanostructured substrates of various types was studied. An optimal thickness of that thin film was discovered that allows one to increase in the photocurrent density of the photoanode up to 400%.

Published: January 2023

Background: Although motor limitations are not currently considered clinical manifestations of autism spectrum disorder (ASD), they should not be ignored because of their high incidence and considerable influence on functional activity. Objective: This study aimed to investigate the relationship between autistic features, motor function, and quality of life (QoL) in children with ASD. Methods: Sixty children diagnosed with ASD from both sexes participated in this study. They were assessed for autistic features, motor skills, and QoL using the Childhood Autism Rating Scale, Peabody Developmental Motor Scale, and the Arabic version of the Pediatric Quality of Life generic core scale. Results: There was a significant negative correlation (p<0.001) between autistic features and QoL and a significant negative correlation (p<0.001) between autistic features and gross motor function, with Pearson correlation coefficients of -0.794 and -0.736, respectively. While the Pearson correlation coefficient was 0.834, there was a significant positive correlation (p<0.001) between gross motor function and QoL. With a p-value (p<0.001), linear regression analysis revealed that autistic features are a highly significant predictor of QoL and gross motor function. Furthermore, gross motor function was a highly significant predictor of QoL (p<0.001). Conclusion: Autistic features adversely affect motor function and QoL in children with an autism spectrum disorder.
Modelling L1 and the artificial language during artificial language learning
Authors: Tang Kevin , Baer-Henney Dinah
Published: January 2023

Artificial language learning research has become a popular tool to investigate universal mechanisms in language learning. However, often it is unclear whether the found effects are due to learning, or due to artefacts of the native language or the artificial language, and whether findings in only one language will generalise to speakers of other languages. The present study offers a new approach to model the influence of both the L1 and the target artificial language on language learning. The idea is to control for linguistic factors of the artificial and the native language by incorporating measures of wordlikeness into the statistical analysis as covariates. To demonstrate the approach, we extend Linzen and Gallagher (2017)’s study on consonant identity pattern to evaluate whether speakers of German and Mandarin rapidly learn the pattern when influences of L1 and the artificial language are accounted for by incorporating measures assessed by analogical and discriminative learning models over the L1 and artificial lexicon. Results show that nonwords are more likely to be accepted as grammatical if they are more similar to the trained artificial lexicon and more different from the L1 and, crucially, the identity effect is still present. The proposed approach is helpful for designing cross-linguistic studies.

Authors: Kim Myounghun , Lee Jeonghan , Kim Jinhyeok , Choi Beomseok , Ki Seunghee
Published: January 2023

Background: Some studies have demonstrated that chemotherapy drugs enhance sensitivity to anesthetics owing to its systemic toxicity, while others have demonstrated that chemotherapy drugs have no effect. This study aimed to determine whether neoadjuvant chemotherapy influences the effect-site concentration (Ce) of propofol for sedation in patients with breast cancer. Methods: This study included patients aged 19–75 years who were scheduled to undergo breast cancer surgery under general anesthesia. Patients who received neoadjuvant chemotherapy were assigned to group C, whereas those who never received chemotherapy were assigned to group N. Propofol was administered through an effect-site target-controlled infusion, and the (MOAA/S) score and Bispectral Index (BIS) were recorded. When the plasma concentration and Ce were equal to the target Ce, and if the MOAA/S score did not change, the target Ce was increased by 0.2 μg/ml; otherwise, the Ce was maintained for 2 min and then increased. This process was repeated until the MOAA/S score became 0. Results: No significant differences were observed in Ce values at each sedation level between both groups. Ce values for loss of consciousness (LOC) of groups C and N were 2.76 ± 0.29 and 2.67 ± 0.27 μg/ml (P = 0.285), respectively. However, the BIS value at LOC of group C (63.87 ± 7.04) was lower than that (68.44 ± 6.01) of group N (P = 0.018).Conclusions: Neoadjuvant chemotherapy for breast cancer has no effect on the Ce of propofol for sedation.

Authors: Peña Figueroa Paula Patricia , Sánchez Prada Jacqueline , Ramírez Sánchez Jacqueline
Published: January 2023

Este artículo es resultado de una investigación orientada con el propósito de develar las concepciones y los modelos de gestión de la convivencia escolar de directivos y docentes de instituciones educativas urbanas del sector público y privado de los municipios de Yaguará (Huila) y Flandes (Tolima). La investigación es de carácter cualitativo con diseño etnográfico. Los resultados permiten comprender que las concepciones sobre convivencia escolar transitan entre el conflicto y la conciliación, los valores y el ideal, dando cuenta de la riqueza de los significados inmersos en ellas. Los modelos de gestión de la convivencia escolar, reflejan las dinámicas institucionales caracterizadas por encuentros y desencuentros y los juegos de poder que actúan como dispositivos de control “del otro” y “los otros”. Esos ‘otros’ que también hacen parte de la comunidad educativa y que, desde sus roles específicos, funciones y responsabilidades pueden contribuir a la construcción de una sana convivencia escolar como sujetos de derechos y deberes.
La política educativa colombiana en el gobierno de Misael Pastrana Borrero (1970-1974)
Authors: Sierra Garzón Freddy Alexander
Published: January 2023

El gobierno de Misael Pastrana Borrero finalizó el acuerdo bipartidista del Frente Nacional. Su política educativa no ha sido estudiada a cabalidad desde un plano interno como externo, y mediada por una crítica decolonial. En este orden, se propone un análisis tanto del desarrollo gubernamental como de la injerencia de organismos internacionales en la formulación y ejecución de una política educativa para los colombianos. La política educativa del gobierno de Misael Pastrana Borrero se caracterizó por cumplir las exigencias propias del Frente Nacional y el continuismo del gobierno anterior. Por otro lado, la teoría económica de la modernidad y organizaciones internacionales como Naciones Unidas y la Organización de Estados Americanos, con sus programas de la UNESCO y PREDE respectivamente, con otros acuerdos como la Alianza para el Progreso y el convenio Andrés Bello, orientaron la educación en este territorio.

Published: January 2023

El presente artículo es el resultado de una investigación llevada a cabo en el marco de la Maestría en Educación de la Universidad Católica de Manizales, en ella se abordaron los temas de Formación y Pedagogías del Encuentro, los cuales fueron permeados por la teoría y las metodologías de los estudios asociados con los Imaginarios Sociales. Alrededor de estos asuntos, se buscó la comprensión de los imaginarios sociales de los docentes de dos instituciones de Antioquia, acerca de la formación y de las relaciones establecidas con el Otro, ello fue logrado desde el enfoque y diseño de la complementariedad (Murcia y Jaramillo, 2008). Dicho enfoque, reconoció en un primer momento el principio de reflexividad etnográfica para el acercamiento a las realidades sociales de la Escuela; luego, fueron ahondadas mediante entrevistas en profundidad y procesadas con apoyo del método categorial. La interpretación se realizó desde el análisis del discurso y la triangulación de la información. Los resultados muestran unas apuestas de los maestros por renovar y replantear continuamente su quehacer, haciéndose responsable por el Otro desde la acogida, el diálogo, el encuentro, la mirada, el gesto; comprometiéndose de manera decidida por una educación “otra”, en una Escuela que se piensa para y con el Otro.
Resolución de problemas: escenario del pensamiento crítico en la didáctica de las ciencias
Authors: Zona López Jhon Rodolfo , Giraldo Márquez Juan David
Published: January 2023

Son muchas las perspectivas teóricas que incluyen dentro de los componentes del pensamiento la resolución de problemas. Algunas de estas, la consideran una habilidad (Laskey y Gibson, 1997; Halpern, 1998), otras una actitud (Paul, Elder y Bartell, 2003), un elemento constituyente (Tamayo, Zona y Loaiza, 2014), o el escenario donde se lleva a cabo el pensamiento crítico (Bailin, 2002). A pesar de la dispersión conceptual es evidente cómo la resolución de problemas es parte fundamental en la formación de pensamiento crítico, por esta razón, se realizó un estudio en 163 estudiantes pertenecientes a 5 instituciones educativas de la ciudad de Manizales de los grados 4° y 5° de primaria, en los cuales se recolectó y analizó información a partir de 9 instrumentos, que permitieron diseñar y proponer 6 niveles de resolución de problemas que fueron contrastados con las diferentes perspectivas teóricas, evidenciando mejores desarrollos en los niveles de resolución de problemas mientras avanza la intervención en el aula.

Application of biopolymer in turbidity removal and sludge settling behaviour of travertine-processing wastewater: Performance optimization using response surface methodology (RSM)
Authors: Ebru Taş  , Emmanuel lkechukwu Ugwu  , Eyüp Sabah  , Zeyni Arsoy
Published: January 2023

A flocculation process was performed to treat travertine-processing effluents with a high concentration of suspended solids using an eco-friendly biopolymer. The experiments were conducted through a standard jar test procedure to optimize the process parameters for sludge volume index (SVI) and turbidity removal. The effects of mixing time, suspension pH, and polymer dosage on treatment efficiency were investigated using central composite design, a standard technique in response surface methodology. The constructed response model was tested using the analysis of variance (ANOVA). Using the Design-Expert tool, the coefficients of regression models were computed. The Fischer value (F-value) was used to evaluate the significance and validity of the predicted model, while the coefficient of determination (R2) was applied to estimate the model significance by comparing the predicted data with the measured data. The optimized parameters obtained were polymer dose of 276.20 mg/L, suspension pH of 8.60, and mixing time of 4.20 min. The optimal SVI and turbidity values obtained were 1.36 mL/g and 2.99 NTU, respectively. Additionally, R2 values for SVI and turbidity were determined as 0.9337 and 0.8654, respectively. Also, the difference between adjusted R2 values and predicted R2 was less than 0.2. Validation tests showed that the response surface methodology is an effective method for optimizing the flocculation mechanism.
Does Public Debt and Investments Create Crowding-out Effect in Turkey? Evidence from ARDL Approach
Authors: SERİN Şeref Can , DEMİR Murat
Published: January 2023

The impact of public sector debt composition on the private sector is a matter of curiosity. This article explores the crowding-out effect of public debt and public investment on private investment in Turkey from 1975 to 2020, utilising the ARDL method. The findings reveal that public investment, public domestic debt stock, and external debt service create a crowding-out effect; on the other hand, the public external debt stock has a crowding-in effect on private sector investments. In this study, the crowding-out effect of public debt, which has not been directly related to private sector investments in the literature, is tried to be examined.

Bireye sunulan çerçevenin onun davranışlarında yaratacağı etkiyi ileri süren çerçeveleme kuramı farklı disiplinlerde gerçekleştirilen araştırmalara konu olmuştur. Psikoloji, sosyoloji, iletişim, ekonomi, pazarlama alanlarında kullanılan çerçeveleme kuramı bu araştırmada vergi cezaları açısından ele alınmıştır. Cezanın kendisi negatif bir çerçeve olarak düşünülse de indirim, yapılandırma, af, taksitlendirilerek ödeme yapılması gibi durumlarda vergi mükelleflerine veya sorumlularına pozitif çerçeve sunulmaktadır. Kimi ülkelerde ise vergi ceza affı olmaması, ödenmeme durumunda kredibilitenin düşmesi veya ticari faaliyetlerin askıya alınması şeklinde yapılan uygulamalar ile mükellefler veya sorumlular negatif çerçeveye maruz kalmaktadırlar. Bu çalışmanın amacı vergi cezaları kapsamında farklı iki uygulamaya sahip ülkenin çerçeveleme kuramı kapsamında değerlendirilmesidir. Türkiye’de uygulanan vergi cezaları politikasının pozitif, Rusya’da uygulanan politikaların ise negatif çerçeve olarak belirlendiği bu araştırmada farklı çerçevelerin vergi cezalarına etkisi incelenmiştir. Araştırma sonucunda kamu bütçesi içinde vergi gelirlerinin payı yüksek olan ülkelerde pozitif çerçevenin daha makul olduğu ortaya konulmuştur.

Discovery of RNA and DNA viruses using next-generation sequencing: Metagenomics v1
Authors: Tong Lily
Published: January 2023

Next-generation sequencing is a powerful tool for viral genomics. Viruses often constitute a very small proportion of any given sample meaning that methods that enable detection of viral nucleic acids are frequently needed for detection and characterisation. Improvement of sensitivity can be achieved by depletion of unwanted nucleic acid during sample pre-treatment or by enrichment such as PCR amplification with virus specific primers, or probe-based targeted enrichment. However, some methods for specific enrichment rely on prior knowledge of the viruses. Here we describe a method for next-generation sequencing to identify unknown viruses (see Figure 1). Following simultaneous extraction of RNA and DNA samples are split into two and subjected to non-specific treatments that deplete host nucleic acids and improve chances of detecting RNA or DNA viruses, respectively. Illumina sequencing libraries are then prepared and these metagenomic libraries can directly sequenced. These sequencing libraries can then be subjected to targeted enrichment using a pan-viral probe set to achieve higher sensitivity (for details see accompanying protocol Discovery of RNA and DNA viruses using next-generation sequencing: Targeted enrichment). We applied this approach to an outbreak of acute hepatitis of unknown aetiology in children, enabling the identification of adeno-associated virus 2 (AAV2) in all patients but not in samples from controls. This method also led to the identification of adenovirus and human herpesviruses. This protocol describes the pre-treatment of nucleic acid extracts to improve detection of DNA and RNA viral reads followed by Illumina library preparation and metagenomic sequencing.

Published: January 2023

INTRDUCCIÓN Para reducir el riesgo de transmisión transfusional se hace necesario fortalecer el componente de diagnóstico precoz de los patógenos asociados a este tipo de transmisión y para lograrlo se necesita conocer la frecuencia de estos agentes infecciosos y su asociación con las características clínicas iniciales en la población de donantes. OBJETIVO Determinar la seroprevalencia de los principales marcadores infecciosos en los donantes atendidos en un banco de sangre con alta cobertura en el departamento de Bolívar, y su asociación con la información obtenida en la encuesta previa al tamizaje serológico. MATERIALES Y MÉTODOS Estudio tranversal, analítico de corte retrospectivo (agosto de 2006 a diciembre de 2010). RESULTADOS Se estudiaron 20264 donantes de sangre consecutivos, encontrándose una seroprevalencia global de 6,2%de casos, con predominio de Anti-HBc (2,62%), seguido de Anti-HCV (1,07%), Anti-T. cruzi (0,83%) y Anti- T. pallidum (0,75%), Anti-HTLV (0,68%), Anti-HIV (0,39%) y HBsAg (0,33%). El 0,33% de los donantes presentó infecciones múltiples. No se encontró diferencia significativa entre la seroprevalencia de los marcadores infecciosos analizados y la medida de edad, la ocupación o el tipo de exposición a comportamientos o procedimientos de riesgo presentes en la población de donantes serorreactivos. CONCLUSIONES Los marcadores infecciosos analizados no presentaron cambios siginificativos en su seroprevalencia excepto Anti-HTLV y es este comportamiento epidemiológico el que permitiría pensar en la aplicación de la estrategia de tamización universal en el departamento de Bolívar.
Procesos, bacterias y arqueobacterias involucrados en el ciclo biológico del nitrógeno para la eliminación de compuestos nitrogenados en ecosistemas de agua dulce, una revisión sistemática
Authors: Galván J. Luis Alberto , Ríos O. Leonardo Alberto
Published: January 2023

Introducción
En los ecosistemas acuáticos, el intercambio de agua ya no se considera una opción adecuada para la gestión en la acuicultura, siendo entonces el interés particular evitar este recambio de agua en la generación de compuestos que contienen nitrógeno, la mejor opción para lograr evitar este recambio de agua es el ciclo biológico del nitrógeno, donde compuestos tóxicos del nitrógeno que se acumulan por los desechos del metabolismo de peces, alimentos no consumidos y materia orgánica, entre otros, son transformados a compuestos nitrogenados menos tóxicos y que se liberan a la atmósfera como gases.
Objetivo
Describir los procesos, bacterias y arqueobacterias reportados en la literatura científica como participes en el ciclo biológico del nitrógeno en ecosistemas de agua dulce.
Materiales y métodos
Se realizó una revisión sistemática de la literatura científica donde se incluyeron los artículos publicados desde el 2002 hasta 2012, disponibles en las bases de datos del sistema de bibliotecas de la Universidad de Antioquia (ScienceDirect, ACS, SpringerLink y PubMed), se utilizaron las palabras claves según la base de datos de descriptores científicos “DecS”, entre ellas “nitrogen cycle”, “bacteria”, “archaea”, “freshwater”, “aquatics ecosystems” y “aquarium”.
Resultados de un total de 383 artículos, se seleccionaron 54 que cumplieron con los criterios de inclusión, a partir de los cuales se describió el ciclo del nitrógeno y los procesos que en él se dan como la nitrificación, la desnitrificación y el proceso anammox, así como también se describen las bacterias y arqueobacterias que participan en estos procesos, las enzimas involucradas en cada proceso y los factores físico-químicos que influyen en el ciclo biológico del nitrógeno, adicionalmente se describen brevemente algunos métodos que han demostrado optimizar la eliminación de compuestos nitrogenados en ecosistemas de agua dulce.
Conclusión
La diversidad de bacterias y arqueobacterias que participan en el ciclo del nitrógeno esta subestimada, debido a la dificultad de aislarlas en el laboratorio por los métodos tradicionales, además se concluye que se necesitan estudios que demuestren las diversas interacciones de los diferentes tipos de microorganismos que participan en el ciclo del nitrógeno en otros hábitats naturales.

Introducción: el almacenamiento incorrecto de los cepillos dentales propicia la contaminación por microorganismos que no hacen parte de la microbiota oral y cuando acceden a la boca pueden ocasionar enfermedades. El objetivo de esta investigación fue determinar la presencia de bacilos Gram negativos fermentadores de glucosa en cepillos dentales, utilizados por una población de estrato socioeconómico intermedio. Métodos: estudio descriptivo de corte transversal. Se analizaron un total de 50 cepillos dentales pertenecientes a individuos de estrato socioeconómico intermedio. Se tomaron dos muestras de cada uno de los cepillos dentales por medio de frotis y se realizaron inoculaciones en medios de cultivo para análisis microbiológico. Se evaluó también la forma de almacenamiento del cepillo y la distancia en metros entre el cepillo y el inodoro. Resultados: el crecimiento bacteriano fue positivo en 58 % de los cultivos; de los cuales se aislaron bacilos Gram negativos fermentadores de glucosa en el 87,9 % de los casos, y de estos el 37,2 % correspondieron a Enterobacter cloacae. La forma de almacenamiento de los cepillos más frecuente fue en recipiente con tapa, ubicados en gaveta con puerta en el 34 % de los casos, y la distancia más larga de los cepillos con el inodoro fue de 3 metros en el 44 % de los casos. Conclusiones : los resultados indican una importante contaminación de los cepillos dentales con bacilos Gram negativos fermentadores de glucosa, especialmente con Enterobacter cloacae.
