ENCRUCIJADA EN LA EDUCACIÓN ¿PODREMOS MEJORAR LA PRUEBA PISA EN LOS PAÍSES DE LA REGIÓN?
Authors: Canavesi Rimbaud Marie Lissette , Tomioka Suzuki Manuel Angel 
Published: May 2021

El programa para la Evaluación Internacional de Alumnos (PISA) de la OCDE, nació con el objetivo de evaluar a los alumnos de aproximadamente 15 años, los mismos que se encuentran casi al finalizar la educación obligatoria, lo que permite medir el grado de conocimiento y habilidades que han obtenido antes de insertarse en la comunidad, frente a los desafíos que ésta plantea. Preocupa la gran diferencia obtenida en el PISA 2012, entre los países del primer mundo y los ocho (8) países latinoamericanos que participaron. Conforme avanzan los años, la diferencia se acrecienta y si no se corrigen de inmediato, ocasionarán mayores desigualdades sociales como está sucediendo actualmente en varios países de América Latina. El libro Gestión de Sistemas Educativos con Calidad, que demuestra el camino a seguir para obtener la Calidad Educativa, nos guía para enfrentar las próximas evaluaciones PISA 2015, 2018 …, al sugerir medidas urgentes e inmediatas que deben ser adoptadas para mejorar los niveles educativos. El crecimiento sostenido que mantenían muchos de los países latinoamericanos en la década anterior (2000-2010) gracias a la exportación de las materias primas y el precio de éstas,está llegando a su fin provocando una desaceleración y deterioro de la economía, y por lo que los gobiernos han dejado de invertir en educación de calidad, en ciencia y tecnología (calidad, productividad e innovación). Una buena educación en matemáticas, ciencia y tecnología hubiera

Umbrales y prototipos: introducción al debate en torno a los estándares de prueba
Authors: Páez Andrés 
Published: May 2021

Existen diversas perspectivas acerca de cómo se deben entender los estándares de prueba en el derecho. En el trabajo central de este número, Rodrigo Coloma sugiere que estos pueden ser entendidos como umbrales o como prototipos. Además, Coloma hace una taxonomía de los diferentes usos de los estándares de prueba que trasciende su simple función como distribuidores de errores. En sus réplicas al artículo, Raymundo Gama y Claudio Agüero hacen valiosas precisiones y serias críticas a esta forma de entender los estándares de prueba. Algunas de estas críticas dan en el blanco mientras que otras van dirigidas más a los presupuestos teóricos que a las tesis mismas de Coloma. En este artículo ofrezco un contexto más amplio para evaluar sus desacuerdos.

Prospects and Challenges of Telemedicine at the Primary Health Care Level: A Basis for Certification of Providers in Ghana
Authors: Antwi James , Opoku-Mensah Daniel 
Published: May 2021

Background: Telemedicine has proven to be one of the modern medical discoveries in recent times, serving as a technological tool to deliver healthcare at a distance and providing medical solutions to remote communities with limited access to quality healthcare. However, the challenges associated with the use of telemedicine in Ghana make it difficult to scale up its application at the Primary Healthcare (PHC) level.
Aim: The aim of the study was to assess the current trends and applications of telemedicine in health care delivery at the primary health care level in Ghana. The study also sought to identify the prospects and challenges of telemedicine implementation in Ghana.
Study Design: The study employed both qualitative and quantitative design involving 200 respondents made up of 80 healthcare professionals and 120 patients from four primary healthcare facilities in the Ahafo-Ano North District of the Ashanti region of Ghana
Methods: Survey questionnaire, semi-structured interview guide, and field observations were used to find out the knowledge of providers, capacity, availability of network infrastructure, and challenges of implementing telemedicine at the PHC level from the viewpoint of healthcare 'professionals' and to verify factors that can persuade patients to participate in the implementation of telemedicine. Logistic regression analysis was conducted to estimate the factors influencing 'patients' decision to participate in telemedicine, while the qualitative data were analyzed using thematic content analysis.
Results: The results show that knowledge and education about telemedicine, easy access to specialist care at home, widespread use of mobile telephony, and reduction in travel cost due to telemedicine significantly influence both providers' and patients' participation in telemedicine at the primary healthcare level. The minimum educational level for patients to participate in telemedicine implementation is a primary education (OR = 0.233, p<0.025). On the other hand, inadequate infrastructure, legal issues such as non-certification of providers, reimbursement and confidentiality challenges are some of the factors that impede telemedicine implementation.
Conclusion: The authors suggest that developing countries need to take advantage of the massive use of mobile telephony and embrace telemedicine application to increase access to healthcare in rural areas. Again, certification of care providers is critical for effective application and integration of telemedicine and this should be adaptive to local needs, high internet connectivity and the demands of both healthcare professionals and patients especially in rural communities.

Published: May 2021

ObjectiveIron has been implicated in the pathogenesis of brain injury and hydrocephalus after preterm germinal matrix hemorrhage‐intraventricular hemorrhage, however, it is unknown how external or endogenous intraventricular clearance of iron pathway proteins affect the outcome in this group.MethodsThis prospective multicenter cohort included patients with posthemorrhagic hydrocephalus (PHH) who underwent (1) temporary and permanent cerebrospinal fluid (CSF) diversion and (2) Bayley Scales of Infant Development‐III testing around 2 years of age. CSF proteins in the iron handling pathway were analyzed longitudinally and compared to ventricle size and neurodevelopmental outcomes.ResultsThirty‐seven patients met inclusion criteria with a median estimated gestational age at birth of 25 weeks; 65% were boys. Ventricular CSF levels of hemoglobin, iron, total bilirubin, and ferritin decreased between temporary and permanent CSF diversion with no change in CSF levels of ceruloplasmin, transferrin, haptoglobin, and hepcidin. There was an increase in CSF hemopexin during this interval. Larger ventricle size at permanent CSF diversion was associated with elevated CSF ferritin (p = 0.015) and decreased CSF hemopexin (p = 0.007). CSF levels of proteins at temporary CSF diversion were not associated with outcome, however, higher CSF transferrin at permanent CSF diversion was associated with improved cognitive outcome (p = 0.015). Importantly, longitudinal change in CSF iron pathway proteins, ferritin (decrease), and transferrin (increase) were associated with improved cognitive (p = 0.04) and motor (p = 0.03) scores and improved cognitive (p = 0.04), language (p = 0.035), and motor (p = 0.008) scores, respectively.InterpretationLongitudinal changes in CSF transferrin (increase) and ferritin (decrease) are associated with improved neurodevelopmental outcomes in neonatal PHH, with implications for understanding the pathogenesis of poor outcomes in PHH.

Published: May 2021

AbstractThe goals of PhenX (consensus measures for Phenotypes and eXposures) are to promote the use of standard measurement protocols and to help investigators identify opportunities for collaborative research and cross‐study analysis, thus increasing the impact of individual studies. The PhenX Toolkit (https://www.phenxtoolkit.org/) offers high‐quality, well‐established measurement protocols to assess phenotypes and exposures in studies with human participants. The Toolkit contains protocols representing 29 research domains and 6 specialty collections of protocols that add depth to the Toolkit in specific research areas (e.g., COVID‐19, Social Determinants of Health [SDoH], Blood Sciences Research [BSR], Mental Health Research [MHR], Tobacco Regulatory Research [TRR], and Substance Abuse and Addiction [SAA]). Protocols are recommended for inclusion in the PhenX Toolkit by Working Groups of domain experts using a consensus process that includes input from the scientific community. For each PhenX protocol, the Toolkit provides a detailed description, the rationale for inclusion, and supporting documentation. Users can browse protocols in the Toolkit, search the Toolkit using keywords, or use Browse Protocols Tree to identify protocols of interest. The PhenX Toolkit provides data dictionaries compatible with the database of Genotypes and Phenotypes (dbGaP), Research Electronic Data Capture (REDCap) data submission compatibility, and data collection worksheets to help investigators incorporate PhenX protocols into their study design. The PhenX Toolkit provides resources to help users identify published studies that used PhenX protocols. © 2021 The Authors.

Does Type, Quantity, and Location of Habitat Matter for Fish Diversity in a Great Plains Riverscape?
Authors: Hitchman Sean M , Mather Martha E , Smith Joseph M 
Published: May 2021

Abstract
Fisheries professionals frequently measure habitat type and amount, but less often measure the importance of where those habitats are located and in what combinations. We address this challenge by testing whether the individual and combined type, quantity, and location of habitat affects fish diversity in the upper Neosho River basin, Kansas, as a different approach to measuring habitat heterogeneity. Habitat type mattered in that species richness increased in areas of higher riffle density. Furthermore, variation within habitat type also influenced fish diversity; specifically, slower, shallower riffles had more species of fish. The spatial arrangement (i.e., impact of neighbor habitats) influenced fish diversity patterns in that riffle–run and riffle–glide pairings altered riffle habitat characteristics. The study illustrates a useful approach by measuring the type, amount, and arrangement of habitats to assess fish populations and could be adapted to other stream ecosystems.
Spectral analysis of physiological brain pulsations affecting the BOLD signal

Published: May 2021

AbstractPhysiological pulsations have been shown to affect the global blood oxygen level dependent (BOLD) signal in human brain. While these pulsations have previously been regarded as noise, recent studies show their potential as biomarkers of brain pathology. We used the extended 5 Hz spectral range of magnetic resonance encephalography (MREG) data to investigate spatial and frequency distributions of physiological BOLD signal sources. Amplitude spectra of the global image signals revealed cardiorespiratory envelope modulation (CREM) peaks, in addition to the previously known very low frequency (VLF) and cardiorespiratory pulsations. We then proceeded to extend the amplitude of low frequency fluctuations (ALFF) method to each of these pulsations. The respiratory pulsations were spatially dominating over most brain structures. The VLF pulsations overcame the respiratory pulsations in frontal and parietal gray matter, whereas cardiac and CREM pulsations had this effect in central cerebrospinal fluid (CSF) spaces and major blood vessels. A quasi‐periodic pattern (QPP) analysis showed that the CREM pulsations propagated as waves, with a spatiotemporal pattern differing from that of respiratory pulsations, indicating them to be distinct intracranial physiological phenomenon. In conclusion, the respiration has a dominant effect on the global BOLD signal and directly modulates cardiovascular brain pulsations.
Computational investigation and screening of high‐energy‐density materials: Based on nitrogen‐rich 1,2,4,5‐tetrazine energetic derivatives
Authors: Zeng Lian , Jiang Yuhe , Wu Jinting , Li Hongbo , Zhang Jianguo 
Published: May 2021

AbstractIn this work, the geometric structure of thirty six 1, 2, 4, 5‐tetrazine derivatives (FTT) were systematically studied by using the density functional theory. Meanwhile, we also predicted the stability, detonation properties, heats of formation (HOF) and thermodynamic properties of all FTT compounds. Results showed that all compounds have superior HOF far exceeding that of common explosives. In addition, the detonation performance (Q = 1426–1804 cal g−1; P = 29.54–41.84 GPa; D = 8.02–9.53 km s−1), which is superior to 2,4,6‐triamino‐1,3,5‐trinitrobenzene 2,4,6‐triamino‐1,3,5‐trinitrobenzene (TATB). It is also concluded that the introduction of coordination oxygen on the tetrazine ring can improve the HOF, density and detonation performance of the title compound, and –NH–NH– bridge and –NHNO2 group are also the perfect combination to increase these values. In view of thermal stability, because of the fascinating performance of D3, E3, F1 and F3 , makes them very attractive to be chosen as HEDMs.

Published: May 2021

Key messageGranulation tissue formation is one of the late complications of tracheostomy. It can cause stomal stenosis secondary to chondritis because of disproportionate excision of the anterior cartilage. Clinicians should carefully determine the incision point, which is typically located half way between the cricoid cartilage and the sternal notch.
Can soil organic carbon be enhanced by using construction wastes as a soil amendment?
Authors: Guerin Turlough F. 
Published: May 2021

AbstractMany soils are low in organic carbon as is the case in Australia. The current study identified the risks from applying shredded end of life packaging materials (EOLPM) to soil at a utility scale solar energy plant, assessed its impact, and mitigated the residual risks. Its purpose was to determine if the EOLPM would pose a potential risk to human health and/or the environment if placed as a amendment incorporated into the surface soil (as a surface‐incorporated mulch) to increase soil carbon. A qualitative risk assessment showed effective controls and risk treatments from the potential risks from combustion, dust generation, and on‐site and off‐site littering (from cardboard pieces), were possible and reduced these residual risks to low (and acceptable) when the EOLPM was shredded and incorporated into the surface soil as an amendment (soil improver).
