A higher proportion of ermin-immunopositive oligodendrocytes in areas of remyelination
Authors: Ahmad Intakhar , Wergeland Stig , Oveland Eystein , Bø Lars
Published: August 2021

Incomplete remyelination is frequent in multiple sclerosis (MS)-lesions, but there is no established marker for recent remyelination. We investigated the role of the oligodendrocyte/myelin protein ermin in de- and remyelination in the cuprizone (CPZ) mouse model, and in MS. The density of ermin+ oligodendrocytes in the brain was significantly decreased after one week of CPZ exposure (p < 0.02). The relative proportion of ermin+ cells compared to cells positive for the late-stage oligodendrocyte marker Nogo-A increased at the onset of remyelination in the corpus callosum (p < 0.02). The density of ermin-positive cells increased in the corpus callosum during the CPZ-phase of extensive remyelination (p < 0.0001). In MS, the density of ermin+ cells was higher in remyelinated lesion areas compared to non-remyelinated areas both in white- (p < 0.0001) and grey matter (p < 0.0001) and compared to normal-appearing white matter (p < 0.001). Ermin immunopositive cells in MS-lesions were not immunopositive for the early-stage oligodendrocyte markers O4 and O1, but a subpopulation was immunopositive for Nogo-A. The data suggest a relatively higher proportion of ermin immunopositivity in oligodendrocytes compared to Nogo-A indicates recent or ongoing remyelination.

Published: August 2021

Introduction

This study aims to explore gender-related differences in persistent opioid use following an acute pain episode and evaluate potential explanatory variables.

Methods

This retrospective population-based study using administrative databases included all opioid-naïve patients in Ontario with renal colic between 2013 and 2017. The primary outcome was to assess any association between persistent opioid use at 3–6 months by gender. Key confounding covariates and explanatory variables examined included both care- and patient-related factors, specifically past evidence of mental health diagnoses.

Results

The dataset of 64,240 males and 37,656 females demonstrated that 8.7% of males and 9.6% of females had evidence of persistent opioid use 3–6 months after presentation (OR 1.11, 95% CI 1.05, 1.17). Females had a higher incidence of mental health services utilization [44.5% vs 29.6% (p<0.001)] and were more likely to be on a provincial disability program [5.1% vs 3.8% (p<0.001)]. Age, income quintile, mental health diagnoses and dose of opioid prescribed were associated with the primary outcome in both genders. On adjusted analysis for multiple confounding and explanatory variables, females were still more likely than males to demonstrate persistent opioid use (OR 1.07, 95% CI 1.01, 1.13) with even more pronounced associations at 1–2 years.

Interpretation

After controlling for key covariates, females are at slightly higher risk of demonstrating long term opioid use following an episode of renal colic. Evidence of prior mental health service utilization and acute colic care did not appear to significantly explain these observations.
Relationship between trust and patient involvement in medical decision-making: A cross-sectional study

Published: August 2021

Introduction

Patients vary in their preferences regarding involvement in medical decision-making. Current research does not provide complete explanation for this observed variation. Patient involvement in medical decision-making has been found to be influenced by various mechanisms, one of which could be patients’ trust in physicians. The aim of this study was to examine whether trust in physicians fosters or impairs patient involvement in medical decision-making. This study also aimed to determine to what extent the relationship between trust and preferences regarding decision-making roles was influenced by the sociodemographic characteristics of the patients. We hypothesised that trust can both foster and impair patient involvement in medical decision-making.

Materials and methods

A survey was sent out to members of the Nivel Dutch Health Care Consumer Panel in February 2016 (response rate = 47%, N = 703). The Wake Forest Physician Trust Scale was used to measure trust. Patient involvement was measured using two items based on the study published by Flynn and colleagues in 2006. Multiple regression analysis was used to analyse the relationship between trust and patient involvement.

Results

We found a negative relationship between trust and patient involvement in medical decision-making in men. Women with high trust reported to be more involved in medical decision-making compared to men with high trust.

Conclusion

The results suggest that trust impairs involvement in medical decision-making for men but not for women. Further research could provide a more comprehensive explanation of the variation in patient preferences regarding involvement in medical decision-making to further elucidate which underlying mechanisms could enhance patient participation.

Background

The World Health Organization has set a goal of hepatitis C virus (HCV) elimination by the year 2030. However, no regions in Japan have succeeded in eradicating HCV. Micro-elimination is an approach to attain hepatitis C eradication in which national eradication goals are applied to specific populations so that viral treatment and control efforts can move forward quickly and efficiently. In order to eradicate HCV from Japan, this study aims to achieve HCV micro-elimination in the town of Nagawa.

Methods and design

The Nagawa Project is an ongoing, prospective, multiple-institution, observational study running from April 1, 2021, to March 31, 2024. All residents of Nagawa town, excluding those under 20 years of age, not consenting to the study, or unable to undergo health check-ups due to nursing care needs, will be included. If found to be HCV antibody-positive, the participant will be recommended to see a doctor in consideration of MAC-2 binding protein glycosylation isomer values. Then, the participant will undergo serum HCV RNA measurement with the real-time polymerase chain reaction by an attending physician. If the participant is HCV RNA-positive, he or she will be referred to a hepatologist for further evaluation. In the case of a definitive diagnosis of chronic hepatitis C, direct acting antiviral treatment will be initiated. Through this process, HCV will be systematically micro-eliminated from the region.

Discussion

The Nagawa Project will reveal the prevalence of chronic HCV in addition to the HCV eradication rate in Nagawa town towards achieving HCV micro-elimination.

The role of culturally responsive social and emotional learning in supporting refugee inclusion and belonging: A thematic analysis of service provider perspectives
Authors: Bennouna Cyril , Brumbaum Hannah , McLay Molly M. , Allaf Carine , Wessells Michael , Stark Lindsay
Published: August 2021

Young refugees resettled to the U.S. from the Middle East and North Africa (MENA) region face significant acculturative stressors, including language barriers, unfamiliar norms and practices, new institutional environments, and discrimination. While schools may ease newcomer adjustment and inclusion, they also risk exacerbating acculturative stress and social exclusion. This study seeks to understand the opportunities and challenges that schoolwide social and emotional learning (SEL) efforts may present for supporting refugee incorporation, belonging, and wellbeing. We completed semi-structured interviews with a purposive sample of 40 educators and other service providers in Austin, Texas, Harrisonburg, Virginia, and Detroit Metropolitan Area, Michigan as part of the SALaMA project. We conducted a thematic analysis with transcripts from these interviews guided by the framework of culturally responsive pedagogy. The findings revealed that students and providers struggled with acculturative stressors and structural barriers to meaningful engagement. Schoolwide SEL also provided several mechanisms through which schools could facilitate newcomer adjustment and belonging, which included promoting adult SEL competencies that center equity and inclusion, cultivating more meaningfully inclusive school climates, and engaging families through school liaisons from the newcomer community. We discuss the implications of these findings for systemwide efforts to deliver culturally responsive SEL, emphasize the importance of distinguishing between cultural and structural sources of inequality, and consider how these lessons extend across sectors and disciplinary traditions.
Health emergencies and interoceptive sensibility modulate the perception of non-evidence-based drug use: Findings from the COVID-19 outbreak
Authors: Salvato Gerardo , Ovadia Daniela , Messina Alessandro , Bottini Gabriella
Published: August 2021

Scientific evidence plays an important role in the therapeutic decision-making process. What happens when physicians are forced to make therapeutic decisions under uncertainty? The absence of scientific guidelines at the beginning of a pandemic due to an unknown virus, such as COVID-19, could influence the perceived legitimacy of the application of non-evidence-based therapeutic approaches. This paper reports on a test of this hypothesis, in which we administered an ad hoc questionnaire to a sample of 64 Italian physicians during the first wave of the COVID-19 pandemic in Italy (April 2020). The questionnaire statements regarding the legitimacy of off-label or experimental drugs were framed according to three different scenarios (Normality, Emergency and COVID-19). Furthermore, as the perception of internal bodily sensations (i.e., interoception) modulates the decision-making process, we tested participants’ interoceptive sensibility using the Multidimensional Assessment of Interoceptive Awareness (MAIA). The results showed that participants were more inclined to legitimate non-evidence-based therapeutic approaches in the COVID-19 and Emergency scenarios than the Normality scenario. We also found that scores on the MAIA Trusting subscale positively predicted this difference. Our findings demonstrate that uncertain medical scenarios, involving a dramatic increase in patient volume and acuity, can increase risk-taking in therapeutic decision-making. Furthermore, individual characteristics of health care providers, such as interoceptive ability, should be taken into account when constructing models to prevent the breakdown of healthcare systems in cases of severe emergency.
Hungry, hungry hikers: Fitness, cooking, and gender in American hiking, 1890s–1920s
Authors: Blower Nicholas
Published: August 2021

This article examines the recollections of American mountaineers and hikers written between the 1890s and 1920s to interrogate the evolving relationship hikers had with food consumption and physical fitness on the trail. It centres firstly on the trail accounts of Appalachian Mountain Club (1876) and Sierra Club (1892) members, before moving towards articles that appeared in outdoor recreation magazines such asOuting.Contrasting itself with existing scholarly work that has focused on the ecological impact of industrial food systems within environmental history, this article seeks to explore the unexamined social and cultural power of food on early American outdoorsmen and women. By highlighting the high-altitude discourses surrounding food and physical ability on the mountainside, the article demonstrates how potentially productive debates about food and modernity are complicated by contemporary ideas of gender and propriety. It also further demonstrates how early suspicions about nutritional science and the privileged, often-chauvinistic culture of American mountaineering limited the ability of these wealthy fitness communities to communicate a wider message about the nation’s shifting health fortunes.
Large-area inventory of species composition using airborne laser scanning and hyperspectral data

Published: August 2021

Tree species composition is an essential attribute in stand-level forest management inventories and remotely sensed data might be useful for its estimation. Previous studies on this topic have had several operational drawbacks, e.g., performance studied at a small scale and at a single tree-level with large fieldwork costs. The current study presents the results from a large-area inventory providing species composition following an operational area-based approach. The study utilizes a combination of airborne laser scanning and hyperspectral data and 97 field sample plots of 250 m collected over 350 km of productive forest in Norway. The results show that, with the availability of hyperspectral data, species-specific volume proportions can be provided in operational forest management inventories with acceptable results in 90% of the cases at the plot level. Dominant species were classified with an overall accuracy of 91% and a kappa-value of 0.73. Species-specific volumes were estimated with relative root mean square differences of 34%, 87%, and 102% for Norway spruce ( (L.) Karst.), Scots pine ( L.), and deciduous species, respectively. A novel tree-based approach for selecting pixels improved the results compared to a traditional approach based on the normalized difference vegetation index.22Picea abiesPinus sylvestris
Snake bite management in a toddler: a case report in Sumbawa Besar
Authors: Liwang Ferry , Nuraeni Fitria , Karyanti Mulya R.
Published: August 2021

Snake bite is an often-neglected,1 life-threatening emergency prevalent in rural areas of tropical countries such as Indonesia.2 The WHO reported a worldwide incidence of 5 million snake bites per year, with 100,000–200,000 deaths.3 The incidence rate and likelihood of subsequent complications are higher in children than adults.4 According to the WHO, 35% of child deaths related to poisonous animal bites are attributable to snake bites and occur more frequently in boys than girls.5 In Indonesia, no national epidemiological data on snake bites in children is available, but the WHO estimated that 5–8 snake bite cases occur weekly in Lombok, West Nusa Tenggara.6

Lower limbs are the most common site for bites (72%), while facial bites are quite rare (10%).7 Bites involving children and/or the face are considered as severe envenomation and usually require antivenom at an appropriate dose and timing to be effective.8 Therefore, it is important that hospitals are equipped with life-saving intervention measures to optimize care and improve the chances of survival.9 Nevertheless, in developing countries, the use of antivenom is limited by the absence of standardized guidelines, scarcity/unavailability, and high cost.9 In Indonesia, the only antivenom, serum antibisa ular (SABU), is costly and difficult to obtain due to limited quantities, especially in rural areas. Furthermore, SABU is a polyvalent antivenom with low coverage, as it is only indicated for Naja sputatrix, Bungarus fasciatus, and Agkistrodon rhodostoma, despite the numerous other snake species endemic to Indonesia.2
Influence of initial treatment delay on overall survival and event-free survival in childhood acute lymphoblastic leukemia
Authors: Purnama Irenne , Widjajanto Pudjo Hagung , Damayanti Wahyu
Published: August 2021

Background Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Initial treatment delay is a modifiable prognostic factor that significantly affects overall survival (OS) and event-free survival (EFS) of childhood ALL in high-income countries. Nevertheless, the effect of delayed initial treatment in low-middle income countries had not been determined.

Objective To analyze relationships between initial treatment delay with overall survival and event-free survival in children with ALL.

Methods A retrospective study was conducted in children aged < 18 years newly diagnosed with ALL L1 and L2 from January 2013 until December 2018 at Dr. Sardjito Hospital, Yogyakarta. Initial treatment delay was defined as a time interval of more than 3 days between diagnosis and treatment. The outcomes of the study were OS and EFS. Negative events were defined as remission failure, relapse, dropping out, and death. Overall survival (OS) and event free survival (EFS) were analyzed by Kaplan-Meier and log-rank tests.

Results Of 341 subjects, 188 (55.5%) underwent delayed initial treatment. There were no significant relationships between initial treatment delay and OS (HR 0.845; 95%CI 0.548 to 1.302; P=0.445) or EFS (HR=0.937; 95%CI 0.689 to 1.275; P=0.971). Multivariate analysis revealed that age was an independent prognostic factor for both OS (P<0.001) and EFS (P<0.001).

Conclusion Initial treatment delay is not associated with OS or EFS.  Age is an independent predictor for both OS and EFS.

No Microscope Needed: A Macroscopic Presentation of Collagenous Colitis
Authors: Boyd Amanda L. , Leiman David A. , Dufault Darin L.
Published: August 2021

Microscopic colitis (MC) is a common cause of chronic secretory diarrhea with variable etiologies, including nonsteroidal anti-inflammatory drugs. As its name implies, the diagnosis requires consistent histopathologic findings that typically accompany normal-appearing mucosa. However, accumulating evidence suggests that the presence of distinct endoscopic features is associated with MC. We present a case of MC that highlights the importance of recognizing these macroscopic findings because they can aid in diagnosis and have significant management implications.

“Whose Emancipatory Politics?” Toward a Postcolonial Technological Subject
Authors: Jos Avrina
Published: August 2021

With Donna Haraway, a new age of the feminist imaginary was born. This imaginary evocatively constructs new feminist subjectivities that are an amalgam of species, sensibilities and ambiguities. Despite the liberating potential of these imagined cyborgs devoid of normativity, the material digital cultures, and technological cultures, that enabled a social movement to this imagined cyborg was/is at a significantly different place in time without subjectivities. Writing on the “Metaphor and Materiality” of technofeminisms, Judy Wacjman opines, “Haraway is much stronger at providing evocative figurations of a new feminist subjectivity than she is at providing guidelines for a practical emancipatory politics” (101).

This paper intends to extend the possibilities of feminist imaginaries for theorisations of technology by first looking at this gap between imagined and material subjectivities. I ask “Whose emancipatory politics?” to point out that despite their insistence on fragmentations of identity and forms of totalisation, western feminist imaginaries of technology do not convey or derive from an inclusive politics of representation or location. Drawing from feminist historiography and transnational feminist frameworks, I insist on the radical potential of feminist imaginaries that are written and rewritten through transnational endeavours and consideration of “nested differences”. The second part of the paper derives from the first – building on the importance of transnational feminist imaginaries – and asks how? How can western feminist imaginaries expand their potential by transgressing their postmodern notions of subjectivity and agency without abandoning them? Here I introduce the “postcolonial technological subject” as a representational figure for a transnational feminist politics of technology by drawing guidelines for transnational feminist theories of technology. My guidelines are informed by Chandra Talpade Mohanty’s conception of transnational feminism, visions for solidarity such as Black Cyberfeminism, Data Feminism and The Xenofeminist Manifesto.
Rhetoric, Trickery, and Tyranny: Testimonies on Sophists of the Hellenistic period
Authors: Heßler Jan Erik
Published: August 2021

In this article, I would like to provide a reappraisal of sophistic activities during the Hellenistic period. An analysis of passages in Philodemus, Posidonius, and several more fragmentary sources can show that there is a continuous and lively tradition of sophistic teaching and rhetoric from the Classical period until Imperial times. The texts give the impression that characteristic features of Hellenistic sophists point towards the generation of Gorgias and his colleagues as well as towards the star speakers of the Second Sophistic. The traditional but outworn negative image of the Hellenistic sophists and Hellenistic rhetoric in general can be explained as a result of the source situation, the decentralisation of schools and performance spaces, and a Classicistic bias of ancient and modern authors. In the end, the testimonies allow for more conclusions than generally thought. A selection of related sources is provided in an appendix.
La desviación de J. S. Mill: el puesto de las emociones en el Utilitarismo.
Authors: Álvarez Gálvez Íñigo
Published: August 2021

Se afirma a menudo que el utilitarismo (al menos su versión estándar) es incapaz de tomar en cuenta las emociones. Siendo esto así, se afirma que es incapaz de responder (correctamente) a nuestros problemas morales más importantes y que, de hecho, se convierte en una doctrina inútil. Sin embargo, debemos matizar esta acusación diciendo, por un lado, que las emociones tienen, de algún modo, un significativo papel en la teoría de Bentham y que, por otro lado, tienen, indudablemente, un papel central en el utilitarismo de Mill. En este artículo tratamos de mostrar cuál es ese papel y si el uso de las emociones en la teoría de Mill puede ser visto como una especie de desviacionismo de la versión estándar.
Richard Hare en perspectiva.
Authors: Ramírez Calle Olga
Published: August 2021

En los debates meta-éticos contemporáneos los análisis de Hare sobre lenguaje moral han sido, cuando no obviados, clasificados sin mucha dilación junto a superadas formas del  no-cognitivismo humeano. Se ha considerado que los análisis conceptuales de Hare serían objeto de  las mismas críticas esgrimidas contra estas últimas e igualmente inadecuados. En mi opinión esto  supone una deformación de su posición y nos distrae de sus más importantes aportaciones a la  comprensión del lenguaje moral. El presente trabajo pretende mostrar que, si ciertos desajustes en la posición de Hare favorecerían esta lectura, una reformulación de su posición permitirá enfren- tar dichas críticas, ofreciendo un nuevo modelo de la relación entre los aspectos descriptivos y evaluativos en el caso moral que difiere tanto de posiciones realistas como del no-cognitivismo humeano.
Evaluation of marine wood boring organism’s attack on wood materials in the Black Sea coastal region
Authors: Can Ahmet , Sivrikaya Hüseyin
Published: August 2021

Wood has been used in many areas including the marine environment due to its important properties. However, marine borers cause damage that shortens the service life of wooden materials. Marine borers have a wide distribution and employ different attack mechanisms depending on the geographical region. In this study, wood samples prepared from the Pinus sylvestris L. species were subjected to marine exposure for seven months in the Eastern, Central, and Western Black Sea Regions. Results showed that Teredo navalis marine borer was observed in all three regions. The N, Mg, S, Cl, Ca, Fe, Zn, and Pb content of the samples noticeable increased after the marine trial. According to Fourier transform infrared analysis, carbohydrate content of the samples decreased noticeable, while lignin content increased.

Published: August 2021

Achieving mild and efficient extraction of high purity lignin from corncob acid hydrolysis residue is essential for efficient lignin application. In this study, enzymatic/mild acidolysis lignin (EMAL) and deep eutectic solvent (DES)-lignin were extracted from corncob acid hydrolysis residue. The structural features of the two lignin fractions were investigated by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), gel permeation chromatography (GPC), and 31P-nuclear magnetic resonance (31P-NMR). The highest DES-lignin yield of 58.8 wt% was achieved at 120 °C with a choline chloride-to-lactic acid (ChCl-to-Lac) molar ratio of 1:10 and a reaction time of 12 h. The FTIR analysis indicated a higher amount of guaiacyl units in EMAL than DES-lignin. Furthermore, condensation and fragmentation occurred simultaneously under DES pretreatment, but the fragmentation reaction was dominant. The structural characteristics investigated will allow for more effective lignin usage.

Published: August 2021

Families and physicians alike benefit from the advances and ease of the Internet. Similarly, both can be unaware of harmful misinformation circulating the Web. In this article, we describe the presentation of 2 unrelated infants, within 1 week of each other, with vitamin D deficiency rickets and severe extraskeletal manifestations of hypocalcemia, including seizures and cardiac arrest, from homemade, vegan formula found through Pinterest (San Francisco, CA). Despite good parental intentions this formula did not meet macronutrient and micronutrient standards, particularly regarding vitamin D, phosphorus, and calcium content, and led to rare, life-threatening complications in both cases. Before presentation, both patients followed appropriately with their pediatrician and discussed feeding in detail, although neither family disclosed the use of homemade formula. Pediatricians must be aware of these dangerous homemade alternative formulas, consider the manner and depth of their feeding history questioning, and continue to counsel against homemade formula to prevent further harm to children.

Published: August 2021

La introducción de especies exóticas puede afectar negativamente a las especies nativas; por ejemplo, el perro doméstico (Canis lupus familiaris) puede aumentar su riesgo de depredación. Evaluamos el efecto de la presencia de perros y humanos sobre el comportamiento de forrajeo y uso de hábitat del fara, Didelphis pernigra, en un área exurbana en los Andes colombianos. Usamos la técnica de densidades de abandono (DDA), la cantidad de alimento dejada por un forrajeador después de explotar un parche en el que experimenta ganancias decrecientes, y que informa sobre los costos de forrajeo experimentados por un individuo, incluyendo el riesgo percibido de depredación. Medimos las DDA en experimentos en presencia de perro o humano en un área de regeneración natural de bosque andino y en una plantación exótica de Eucaliptus globulus cerca al río Bogotá en Cajicá, Colombia. Los faras utilizaron más el área de regeneración que la plantación; la plantación fue muy poco utilizada. La presencia humana redujo el forrajeo del fara en la regeneración. No se encontró efecto del perro sobre el forrajeo de los faras. Además, el forrajeo también fue afectado por la iluminación de la luna, pero su efecto dependió del periodo de la noche. Este marsupial nativo seleccionó los sitios de forrajeo dependiendo de su exposición a posibles depredadores. El fara no parece reconocer al perro como una amenaza, probablemente incrementando su vulnerabilidad al ataque de estos carnívoros.

Diferentes iniciativas han permitido conocer los sonidos de los mamíferos neotropicales. Aunque en Colombia hay algunos repositorios de registros bioacústicos, la Colección de Sonidos Ambientales Mauricio Álvarez-Rebolledo del Instituto Humboldt (IAvH-CSA) es la única de acceso público. Nuestro objetivo fue explorar la representatividad de mamíferos en la IAvH-CSA y promover su uso entre la comunidad mastozoológica colombiana. Encontramos 129 registros, la mayoría de Primates. Los registros incluyen representación de todas las regiones geográficas, excepto el Catatumbo, y 21 de los 32 departamentos del país. Aun así, solo el 3 % de las especies de mamíferos de Colombia están representadas en la colección. Éstas han sido grabadas en su mayoría por ornitólogos. Por tanto, hacemos un llamado a apoyar los repositorios públicos en nuestro país, depositar los registros acústicos para garantizar accesibilidad a estos y abordar futuras preguntas en la bioacústica de mamíferos de Colombia.

A pesar de los avances en registros primarios de especies, sesgos de calidad y accesibilidad en información dificultan el estudio de patrones espaciales de biodiversidad. Se presenta el primer análisis sistemático sobre los sesgos en la distribución temporal y espacial de registros de mamíferos silvestres terrestres continentales de Colombia. Mediante el uso de bases de datos, identificamos áreas administrativas y ecorregiones con los mayores vacíos de información a nivel de orden para el número de especies registradas respecto al número de especies esperadas. Además, realizamos análisis de complementariedad para establecer áreas prioritarias de muestreo que ayuden a disminuir sesgos en patrones de registro de especies de mamíferos en Colombia. La mayoría de los órdenes (70 %) presentan una representatividad menor al 50 % en al menos 40 % de los departamentos y 60 % de las ecorregiones estudiadas. Además, encontramos que la cobertura temporal en celdas de 50 * 50 km es baja, con promedio inferior a los cuatro años desde 1950 hasta 2019. El análisis de complementariedad muestra que el registro de especies a nivel nacional se maximizaría en los bosques tropicales de la Amazonía en los límites entre el departamento del Caquetá y Amazonas, el escudo Guayanés en la región de la Orinoquia, además de los ecosistemas de sabanas del Vichada, Casanare y Arauca. Proponemos la definición de esquemas depriorización y muestreo sistemático tanto para áreas aisladas y poco conocidas, como para zonas de mayor presión antrópica que pueden sufrir pérdidas locales de especies a corto plazo.

We assessed the influence of terrain variables on the occupancy of the little red brocket deer (Mazama rufina) in the Central Andes of Colombia. Occupancy increased with elevation up to 3000, where it starts decreasing. This information is crucial to predict the potential effects of climate change on M. rufina and other mountain species.
Mamíferos silvestres en plantaciones forestales: ¿Una oportunidad para su conservación?

Las plantaciones forestales son monocultivos que han venido en aumento a nivel mundial. Estos sistemas son menos diversos en comparación con bosques originales, pero pueden aportar a la conservación de la biodiversidad ya que son usadas por muchas especies, incluso algunas amenazadas. Este potencial debe evaluarse en cada localidad. En este trabajo se registró la abundancia relativa y se midió la diversidad verdadera de mamíferos terrestres, arborícolas y voladores, en cinco núcleos forestales de coníferas y de teca en las regiones Andina y Caribe de Colombia, y se comparó con coberturas nativas aledañas. El 78 % y 71 % de los mamíferos presentes en los sitios visitados fueron registrados al interior de las plantaciones de coníferas y teca, respectivamente. Al interior de ambos tipos de plantaciones se encontraron especies amenazadas como Leopardus tigrinus y Saguinus oedipus. Los perfiles de diversidad fueron similares entre bosques y plantaciones en casi todos los grupos. Hubo diferencias significativas solo para los mamíferos terrestres en las plantaciones de coníferas. Se encontraron diferencias en la abundancia relativa entre ambas coberturas para todos los grupos con una tendencia a menor abundancia en las plantaciones, lo cual indica que estas ofrecen un hábitat de menor calidad para los mamíferos silvestres, pero las plantaciones visitadas distan de ser “desiertos verdes” y por el contrario mostraron que son sistemas diversos. La riqueza de especies y la presencia de especies amenazadas son atributos que deben ser incluidos en los planes de manejo forestal y en el diseño del paisaje regional.

Introducción. La infección por SARS-COV2, que en principio se pensó solo causaba manifestaciones respiratorias, también puede ocasionar síntomas gastrointestinales, renales, neurológicos, cardiovasculares e incluso cutáneos según algunos reportes.
Presentación del caso. Paciente femenina de 36 años quien asistió al servicio de urgencias por cuadró clínico consistente en disnea, astenia, adinamia, odinofagia leve y cefalea. Como antecedentes de relevancia se registró obesidad, tabaquismo y ocupación como trabajadora de la salud. Dados los síntomas, se indicó tratamiento antimalárico y antirretroviral para tratar COVID-19, diagnóstico que fue confirmado a los tres días de ingreso, pero al cuarto día de instaurado este manejo la mujer presentó polidipsia y rash macular, pruriginoso y generalizado. Por sospecha de toxicodermia, el tratamiento fue suspendido y con esto el cuadro cutáneo mejoró. Luego de 8 días de hospitalización, la paciente recibió el alta, junto con recomendaciones de bioseguridad y confinamiento durante 28 días.
Conclusiones. El caso descrito corresponde a un evento de toxicodermia en una paciente con COVID-19 en manejo con antirretroviral y antimalárico. A partir de los hallazgos, se establece que la exploración minuciosa de piel y mucosas en los pacientes con sospecha o diagnóstico confirmado de COVID-19 puede ser de gran ayuda para la correcta caracterización de esta nueva enfermedad.

La aplicación de espectroscopia de impedancia eléctrica (EIE), es una técnica que se utiliza para monitorear, detectar y cuantificar microorganismos de interés biotecnológico, con la medición de parámetros eléctricos de respuesta rápida de un medio inoculado a temperatura y agitación constante mediante electrodos sumergidos. Realizando una comparación del modelo de crecimiento y el recuento en placa con los parámetros eléctricos de respuesta, se puede dar una correlación para romper la barrera tecnológica entre la microbiología clásica y los métodos rápidos de detección. La comparación de ambas técnicas fue realizada para determinar el máximo crecimiento de Lactobacillus casei (L. casei) ATCC 393. Se encontró que tras la inoculación, después de 24 h en condiciones microaerofílicas (37 °C), el máximo crecimiento microbiano fue registrado por medio de la EIE, mediante los parámetros |Z| (29,1057) y Deg–Deg0 (24,555°). En contraste con la técnica de conteo en placa, el crecimiento máximo se estimó a las 9 h. Los datos experimentales obtenidos mediante la EIE fueron ajustados por un circuito RC en serie, posteriormente, las curvas generadas fueron ajustadas a los modelos de crecimiento de Gompertz y Boltzman. Usando la técnica de EIE, la impedancia del medio resultó el parámetro más eficiente para la estimación del pico máximo exponencial de crecimiento de L. casei. Se demostró que la EIE constituye una alternativa para la detección rápida de la concentración microbiana en procesos de producción de biomasa para la elaboración de productos alimenticios probióticos.
Micropropagación de Calibanus hookeri (lem.) trel (1911). Una especie amenazada
Authors: Núñez Coronado Cesar , González Rosas Héctor , Fernandez-Pavia Yolanda Leticia
Published: August 2021

La especie Calibanus hookerii perteneciente a la familia Asparagaceae, está registrada en la NOM-059-SEMARNAT-2010 catalogada como planta amenazada. Sus poblaciones naturales se han visto reducidas de manera importante debido a una explotación excesiva y destrucción de su hábitat, por lo que se requiere de métodos de propagación eficaz que aseguren su conservación. La propagación in vitro es una alternativa viable para especies vegetales amenazadas. En la presente investigación se reporta el protocolo para la micropropagación de Calibanus hookerii mediante la germinación de semilla sin testa inoculada en medio MS complementado con 2.5, 5.0 y 7.0 mg L-1 de 6 benciladenina (BA), cinetina (K), 2-isopentil-adenina (2iP) y tidiazuron (TDZ). Las variables a medir fueron porcentaje de germinación, número y longitud de brotes producidos por semilla.
El tratamiento más eficiente fue de 5.0 mg L-1 de BA produciéndose un promedio de 26 brotes por semilla; el tratamiento menos eficaz fue con 2.5 mg L-1 K en el cual solamente se obtuvieron dos brotes por semilla. De las tres concentraciones de 2iP solamente en la concentración de 7 mg. L-1 mostró resultados produciendo 6 brotes por semilla. En lo que respecta a la longitud del brote ningún tratamiento superó al testigo (8.07cm). La eficiencia la germinación in vitro fue de 56-97%.
Acosos, apoyos y amores: en los pliegues de las memorias escolares de varones gays del Área Metropolitana de Buenos Aires, Argentina
Authors: Marentes Maximiliano , Pannelli Ezequiel
Published: August 2021

El objetivo de este trabajo consiste en reconstruir las memorias escolares de varones gays del Área Metropolitana de Buenos Aires, Argentina. El trabajo de campo se basó en un enfoque biográfico estructurado en cuatro entrevistas con 30 varones. Proponemos pensar las memorias escolares como un cartón corrugado, en el que la rigidez de la estructura se debe a los acosos sufridos que, como sinécdoque, tiñen la totalidad de la trayectoria escolar. Sin embargo, al estirar los pliegues de las memorias, aparecen tanto los apoyos que recibieron como los amores que experimentaron en esa época. Trabajar con narrativas de escolaridades finalizadas nos permite iluminar aspectos que, cuando se estudian las experiencias de la diversidad sexual en el ámbito educativo, no suelen aparecer. Como resultado de la investigación, sostenemos que, aunque las malas experiencias escolares de varones gays estructuran sus memorias escolares, estas también se componen de otros recuerdos que las complejizan.
