Authors: Aga Cathrine , Aasen Ingerid Baksaas , Brocker Carsten , Kise Nina Jullum , Heir Stig
Published: December 2021

Purpose

To evaluate patient MRI results, demography and clinical outcome following transtibial repair of lateral and medial meniscal posterior root tears.

Methods

Patients treated with transtibial repairs of posterior meniscal root tears from 2015 through 2018 performed pre- and postoperative MRI scans. Outcome measures were continuity/discontinuity of the meniscal root and change in meniscal extrusion on MRI. Other outcomes were KOOS, Lysholm score, Tegner activity scale and the Global Rate of Change (GRoC) score for function and pain at follow-up.

Study design

Retrospective case-series.

Results

Of 41 patients, 36 attended follow-up at mean 26 (12–38) months postoperatively. At follow-up, 11 out of 18 lateral meniscus posterior root tear (LMPRT) versus 5 out of 18 medial meniscus posterior root tear (MMPRT) repairs were classified as healed. Meniscal extrusion decreased in LMPRTs from of 2.3 ± 1.5 mm to 1.4 ± 1.09 mm (p = 0.080) and increased in MMPRTs from 3.1 ± 1.6 mm to 4.8 ± 1.9 mm (p = 0.005) at FU (between-group difference, p < 0.001). LMPRT repairs were associated with ACL injury and additional meniscal injury and were younger and with lower BMI. No between-group differences were found for KOOS, Lysholm or GRoC Function scores. Tegner scale was higher and GRoC Pain score lower in the LMPRT group compared to the MMPRTs.

Conclusion

Following transtibial repair for meniscal posterior root repairs, the LMPRTs had a higher frequency of healing, whereas most MMPRTs continued to extrude, despite surgical intervention. The study confirmed that LMPRTs and MMPRTs differ in demography and associated injuries.

Published: December 2021

Background

Citizen science is becoming a mainstream approach of baseline data collection to monitor biodiversity and climate change. Dragonflies (Odonata) have been ranked as the highest priority group in biodiversity monitoring for global warming. Ischnura senegalensis Rambur has been designated a biological indicator of climate change and is being monitored by the citizen science project “Korean Biodiversity Observation Network.” This study has been performed to understand changes in the distribution range of I. senegalensis in response to climate change using citizen science data in South Korea.

Results

We constructed a dataset of 397 distribution records for I. senegalensis, ranging from 1980 to 2020. The number of records sharply increased over time and space, and in particular, citizen science monitoring data accounted for the greatest proportion (58.7%) and covered the widest geographical range. This species was only distributed in the southern provinces until 2010 but was recorded in the higher latitudes such as Gangwon-do, Incheon, Seoul, and Gyeonggi-do (max. Paju-si, 37.70° latitude) by 2020. A species distribution model showed that the annual mean temperature (Bio1; 63.2%) and the maximum temperature of the warmest month (Bio5; 16.7%) were the most critical factors influencing its distribution. Future climate change scenarios have predicted an increase in suitable habitats for this species.

Conclusions

This study is the first to show the northward expansion in the distribution range of I. senegalensis in response to climate warming in South Korea over the past 40 years. In particular, citizen science was crucial in supplying critical baseline data to detect the distribution change toward higher latitudes. Our results provide new insights on the value of citizen science as a tool for detecting the impact of climate change on ecosystems in South Korea.

Published: December 2021

Background

A Viabahn stent graft (SG) is a heparin-coated self-expandable SG for lower extremity arterial disease that exhibits high flexibility and accuracy in the delivery system. This study aimed to evaluate the short-term efficacy and safety of emergency endovascular treatment (EVT) using a Viabahn SG for upper and lower extremity arterial bleeding (ULEAB).

Methods

Consecutive patients with ULEAB who underwent emergency EVT using the Viabahn SG between January 2017 and August 2021 were retrospectively reviewed. The indications for EVT, location of artery, technical success, clinical success, limb ischemia, periprocedural complications, bleeding-related mortality, 30-day mortality, diameter of the target artery, diameter of the SG, neck length, rebleeding, endoleaks, and patency of the SGs at 1, 3, 6, and 12 months were evaluated.

Results

EVT using the Viabahn SG was performed in 22 patients (mean age, 72.0 ± 13.0 years; 11 men) and 23 arteries (upper, 6; lower, 17). The indications for EVT were pseudoaneurysm (n = 13, 59.1%), extravasation (n = 9, 39.1%), and inadvertent arterial cannulation (n = 1, 4.3%). The anatomical locations of the 23 ULEAB injuries were the brachiocephalic (1 [4.3%]), subclavian (3 [13.0%]), axillary (1 [4.3%]), brachial (1 [4.3%]), common iliac (4 [17.4%]), external iliac (8 [34.8%]), common femoral (2 [8.7%]), superficial femoral (2 [8.7%]), and popliteal (1 [4.3%]) arteries. The technical and clinical success rates were 100%. The rates of limb ischemia, periprocedural complications, and bleeding-related mortality were 0%, whereas the 30-day mortality rate was 22.7%. The mean diameters of the arteries and SGs were 7.7 ± 2.2 and 8.9 ± 2.3 mm, respectively. The mean neck length was 20.4 ± 11.3 mm. No endoleaks or rebleeding occurred during the follow-up period (mean, 169 ± 177 days). Two SG occlusions without limb ischemia occurred in the external iliac and brachial arteries after 1 and 4 months, respectively. Subsequently, cumulative SG patency was confirmed after 1, 3, 6, and 12 months in 91.7%, 91.7%, 81.5%, and 81.5% of patients, respectively.

Conclusions

Emergency EVT using the Viabahn SG for ULEAB was effective and safe according to short-term outcomes. Appropriate size selection and neck length are important for successful treatment. SG patency was good after 1, 3, 6, and 12 months.

Authors: Ugwu Chidiebere Emmanuel , Suru Stephen Monday
Published: December 2021

Background

Carbon tetrachloride (CCl4) is a well-characterized hepatotoxic agent. With rising cases of liver diseases, the identification, assessment, and development of hepatoprotective agents from plants source has become imperative.

Main body

With arrays of literature on plants with hepatoprotective potentials, this review sourced published literatures between 1998 and 2020 and systematically highlighted about 92 medicinal plants that have been reported to protect against CCl4-induced liver injury in animal models. The results show that herbal plants provide protection for the liver against CCl4 by downregulation of the liver marker enzymes and activation of antioxidant capacity of the liver cells with the restoration of liver architecture. We also provided the traditional and accompanying pharmacological uses of the plants. A variety of phytochemicals mostly flavonoids and polyphenols compounds were suggested to offer protection against liver injuries.

Conclusion

It can be concluded that there are a variety of phytochemicals in plant products with hepatoprotective activity against CCl4-induced toxicity in animal models.

Published: December 2021

Background

A major problem in surgery of peripheral nerve injuries of the upper extremities is the unpredictable final outcome. More insight and understanding of the proper methods of outcome assessment and the prognostic factors is necessary to improve functional outcome after repair of peripheral nerves. The objective of this study is to assess the outcome and identify possible prognostic factors for functional recovery of median and/or ulnar nerves repairs at wrist. Forty patients with median, ulnar or combined median-ulnar nerve injuries were included. Smoking, age, sex, repaired nerve, associated artery and/ or tendon repairs, joint stiffness and scar tissue were analyzed as prognostic factors for functional outcome after repair. Outcome parameters were medical research counsel (MRC) scoring for sensory and motor recovery, grip and pinch strength, disability of arm, shoulder and hand (DASH) questionnaire, electrophysiology and ultrasonographic evaluation.

Results

The mean age of the studied patients was 29.1 ± 8.3 and it was statistically correlated with grip strength (p= 0.045), DASH score (p= 0.046) and hyperesthesia score (p= 0.040). EMG results showed signs of regeneration in all patients in the form of small nascent MUAPs and polyphasic MUAPs. CMAP amplitudes of median and ulnar nerves positively correlated with the MRC scale for muscle strength (p= 0.001)

There were statistically significant negative correlations between DASH score and MRC score for sensory evaluation (p= 0.016), grip (p= 0.001), and pinch strength (p= 0.001). There were statistically significant positive correlations between patient's opinion of recovery and MRC score for sensory evaluation (p= 0.029), grip (p= 0.001), and pinch strength (p= 0.001). The MRC score for muscle strength has statistical significant positive correlations with the MRC score for sensory evaluation, grip (p= 0.003), and pinch strength (p= 0.040)

Conclusions

It was concluded that; MRC scale for muscle power, MRC scale for sensory evaluation, functional scores, grip and pinch strength are valuable tools for evaluation of functional outcome. Age, smoking, associated tendon repair, damaged nerve, compliance to rehabilitation protocol, return to work, clinically visible wound adhesions, residual hand joint stiffness, and scar tissue detected by ultrasound were found to be prognostic factors for outcome after nerve repair.

Published: December 2021

PURPOSE

Because of the negative impact of cancer treatment on female sexual function, effective treatments are warranted. The purpose of this multisite study was to evaluate the ability of two dose levels of extended-release bupropion, a dopaminergic agent, to improve sexual desire more than placebo at 9 weeks, measured by the desire subscale of the Female Sexual Function Index (FSFI), and to evaluate associated toxicities.

METHODS

Postmenopausal women diagnosed with breast or gynecologic cancer and low baseline FSFI desire scores (< 3.3), who had completed definitive cancer therapy, were eligible. Women were randomly assigned to receive 150 mg or 300 mg once daily of extended-release bupropion or a matching placebo. t-tests were performed on the FSFI desire subscale to evaluate whether there was a significantly greater change from baseline to 9 weeks between placebo and each bupropion arm as the primary end point. Sixty-two patients per arm provided 80% power using a one-sided t-test.

RESULTS

Two hundred thirty women were randomly assigned from 72 institutions through the NRG Oncology NCORP network. At 9 weeks, there were no statistically significant differences in change of the desire subscale scores between groups; participants in all three arms reported improvement. The mean changes for each arm were placebo 0.62 (standard deviation [SD] = 1.18), 150-mg once daily bupropion 0.64 (SD = 0.95), and 300-mg once daily bupropion 0.60 (SD = 0.89). Total and subscale scores on the FSFI were low throughout the study, indicating dysfunction in all groups.

CONCLUSION

Bupropion was not more effective than placebo in improving the desire subscale of the FSFI. Subscale and total scores of the FSFI demonstrated dysfunction throughout the 9 weeks of the study. More research is needed to support sexual function in female cancer survivors.
On the von Neumann entropy of language networks: Applications to cross-linguistic comparisons
Authors: Vera Javier , Fuentealba Diego , Lopez Mario , Ponce Hector , Zariquiey Roberto
Published: December 2021

Words are not isolated entities within a language. In this paper, we measure the number of choices transmitted in natural language by means of the von Neumann entropy of language networks. This quantity, introduced in Quantum Information accounts, provides a detailed characterization of network complexities. The simulations are based on a large parallel corpus of 362 languages across 55 linguistic families (focusing on the sub-sample of 85 languages from the Americas). With this, we constructed language networks as a simple way to describe word connectivity patterns for each language. We studied several aspects of the von Neumann entropy of language networks. First, we discovered large groups of languages with low average degree and high von Neumann entropy. The results suggested also that large von Neumann entropy is associated with word entropy (as a proxy for morphological complexity), and is inversely related to degree regularity. This means that there are pressures at play that keep a balance between word morphological complexity and patterns of connections between words. We suggested also a strong influence of functional words on low von Neumann entropy languages. Our approach is thus a simple network-based contribution to establish cross-linguistic language comparisons from textual data.

Lateral Supracerebellar Infratentorial Approach for Superior Oblique Myokymia: A Case Series
Authors: Noro Shusaku , Seo Yoshinobu , Honjo Kaori , Okuma Masahiro , Asayama Bunsho , Amano Yuki , Kyono Masanori , Hashimoto Masato , Hanai Kaori , Nakamura Hirohiko
Published: December 2021

BACKGROUND:

Few reports have shown that superior oblique myokymia (SOM) may result from vascular compression of the trochlear nerve and may be curable using microvascular decompression (MVD).

OBJECTIVE:

To report the clinical characteristics and surgical treatment of 2 cases of SOM and provide a review of the related literature.

METHODS:

Two patients with SOM were treated using MVD with the lateral supracerebellar infratentorial approach. The patients underwent diagnostic magnetic resonance imaging and three-dimensional fusion imaging preoperatively. A lateral suboccipital craniotomy was performed in the park-bench position. The trochlear nerve and branches of the superior cerebellar artery were confirmed after opening the cerebellomesencephalic fissure over the tentorial surface of the cerebellum. The vessel, which compressed the root exit zone of the trochlear nerve, was transposed far from the nerve and attached to the surface of the midbrain using Teflon felt and fibrin glue.

RESULTS:

The first case showed compression on both the ventral and rostral sides of the trochlear nerve root exit zone, and the second showed compression only on the ventral side. Large bridging veins on the tentorial surface of the cerebellum complicated the approach in the second case. Postoperatively, both patients had immediate and complete resolution of symptoms without recurrence at the 24-mo and 17-mo follow-ups, respectively. Five previous reports described the complete resolution of SOM after MVD.

CONCLUSION:

A presentation of an intermittent fluttering ocular sensation should prompt magnetic resonance imaging for ipsilateral trochlear nerve compression. The lateral supracerebellar infratentorial approach allows safe and efficacious MVD for SOM.
Functional significance and physiological regulation of essential trace metals in fish
Authors: Chandrapalan Theanuga , Kwong Raymond W. M.
Published: December 2021

Trace metals such as iron, copper, zinc and manganese play essential roles in various biological processes in fish, including development, energy metabolism and immune response. At embryonic stages, fish obtain essential metals primarily from the yolk, whereas in later life stages (i.e. juvenile and adult), the gastrointestine and the gill are the major sites for the acquisition of trace metals. On a molecular level, the absorption of metals is thought to occur at least in part via specific metal ion transporters, including the divalent metal transporter-1 (DMT1), copper transporter-1 (CTR1), and Zrt- and Irt-like proteins (ZIP). A variety of other proteins are also involved in maintaining cellular and systemic metal homeostasis. Interestingly, the expression and function of these metal transport- and metabolism-related proteins can be influenced by a range of trace metals and major ions. Increasing evidence also demonstrates an interplay between the gastrointestine and the gill for the regulation of trace metal absorption. Therefore, there is a complex network of regulatory and compensatory mechanisms involved in maintaining trace metal balance. Yet, an array of factors is known to influence metal metabolism in fish, such as hormonal status and environmental changes. In this Review, we summarize the physiological significance of iron, copper, zinc and manganese, and discuss the current state of knowledge on the mechanisms underlying transepithelial metal ion transport, metal–metal interactions, and cellular and systemic handling of these metals in fish. Finally, we identify knowledge gaps in the regulation of metal homeostasis and discuss potential future research directions.
The Human Tide: A Review Essay
Authors: Guinnane Timothy W.
Published: December 2021

The Human Tide: How Population Shaped the Modern World, by Paul Morland, argues for the importance of demography in both historical events and our current situation. Intended for a general audience, the book traces demographic developments from the late eighteenth century, arguing that the timing and pace of demographic change helps to explain why some countries became powerful and others did not. The author continues the story into the twentieth century, discussing the changes in age structure and internal ethno-religious balances that are consequences of demographic patterns. Many readers will find the questions and themes in The Human Tide interesting. Unfortunately, the book misrepresents some research findings and is confused about important demographic concepts. The Human Tide deals with fundamental changes in human society over the past two centuries, but for a clear account of those changes, readers will have to go elsewhere.

Book Review: The Great Reversal by Thomas Philippon
Authors: Eeckhout Jan
Published: December 2021

Thomas Philippon’s The Great Reversal: How America Gave Up on Free Markets is a remarkable piece of research that draws our attention to a timely and relevant issue: the rise of market power and its macroeconomic implications. The book documents the facts, offers a number of hypotheses to explain those facts, and discusses the policy interventions needed to remedy market power. This essay reviews the contribution of the book, especially the conceptual and empirical foundations that lead to the main conclusions. The main virtue of the book is to offer a wealth of facts and implications that highlight the different aspects of the evolution of market power. This essay also considers instances that permit an alternative viewpoint. First, I maintain that the reliance on concentration indices to measure market power can be misleading. Second, the essay argues that to date there is no evidence that bestows a different experience in the evolution of market power in Europe compared to the United States. Third, the book gives most air time to antitrust and merger review as the main cause. While antitrust is relevant, technological change is at least as, if not more, important for the observed rise of market power. This essay manifests that technological change has fundamental implications for welfare and therefore for policy intervention. (JEL D24, E22, G31, G34, K21, L13)
A working model for condensate RNA-binding proteins as matchmakers for protein complex assembly
Authors: Chen Xiuzhen , Mayr Christine
Published: December 2021

Most cellular processes are carried out by protein complexes, but it is still largely unknown how the subunits of lowly expressed complexes find each other in the crowded cellular environment. Here, we will describe a working model where RNA-binding proteins in cytoplasmic condensates act as matchmakers between their bound proteins (called protein targets) and newly translated proteins of their RNA targets to promote their assembly into complexes. Different RNA-binding proteins act as scaffolds for various cytoplasmic condensates with several of them supporting translation. mRNAs and proteins are recruited into the cytoplasmic condensates through binding to specific domains in the RNA-binding proteins. Scaffold RNA-binding proteins have a high valency. In our model, they use homotypic interactions to assemble condensates and they use heterotypic interactions to recruit protein targets into the condensates. We propose that unoccupied binding sites in the scaffold RNA-binding proteins transiently retain recruited and newly translated proteins in the condensates, thus promoting their assembly into complexes. Taken together, we propose that lowly expressed subunits of protein complexes combine information in their mRNAs and proteins to colocalize in the cytoplasm. The efficiency of protein complex assembly is increased by transient entrapment accomplished by multivalent RNA-binding proteins within cytoplasmic condensates.

Authors: Abdul Razak Siti Fatimah , Yogarayan Sumendra , Azman Afizan , Abdullah Mohd Fikri Azli , Muhamad Amin Anang Hudaya , Salleh Mazzar
Published: December 2021

Background:V2V (Vehicle-to-Vehicle) is a booming research field with a diverse set of services and applications. Most researchers rely on vehicular simulation tools to model traffic and road conditions and evaluate the performance of network protocols. We conducted a scoping review to consider simulators that have been reported in the literature based on successful implementation of V2V systems, tutorials, documentation, examples, and/or discussion groups.

Methods:Simulators that have limited information were not included. The selected simulators are described individually and compared based on their requirements and features, i.e., origin, traffic model, scalability, and traffic features. This scoping review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The review considered only research published in English (in journals and conference papers) completed after 2015. Further, three reviewers initiated the data extraction phase to retrieve information from the published papers.

Results:Most simulators can simulate system behaviour by modelling the events according to pre-defined scenarios. However, the main challenge faced is integrating the three components to simulate a road environment in either microscopic, macroscopic or mesoscopic models. These components include mobility generators, VANET simulators and network simulators. These simulators require the integration and synchronisation of the transportation domain and the communication domain. Simulation modelling can be run using a different types of simulators that are cost-effective and scalable for evaluating the performance of V2V systems in urban environments. In addition, we also considered the ability of the vehicular simulation tools to support wireless sensors.

Conclusions:The outcome of this study may reduce the time required for other researchers to work on other applications involving V2V systems and as a reference for the study and development of new traffic simulators.

Authors: Edonkumoh Ebiye V. , Ngwuchukwu Margaret N. , Ilo Promise I , Okuonghae Omorodion
Published: December 2021

Aim: The study investigated the awareness of Ebola Virus Disease (EVD) and information seeking behaviour of rural dwellers in Nigeria.
Methods: The survey type of the descriptive research design was used in conducting the study and the study group comprised adult rural dwellers (18 years and above) residing in six communities (Peretoru, Ekeremor, Obrigbene, Enougbene, Amabulou, and Aya-ama) in Bayelsa state, Nigeria. Data were collected from 600 respondents who were randomly selected from the six communities. The data from the study were then analysed using frequency count and percentages. The results were presented in charts (and graphs).
Results: The study revealed that rural dwellers possess low awareness of EVD and many of them do not bother to seek EVD information because they do not believe it exists.
Conclusion: Consequently, the study noted the need for the federal government to enhance structures that promote community engagements, especially at the time of the epidemic.

Authors: Krochmal-Marczak Barbara , Kiełtyka-Dadasiewicz Anna
Published: December 2021

W przeprowadzonych badaniach wykazano wpływ temperatury wody i czasu parzenia na zawartość polifenoli oraz aktywność antyoksydacyjną naparów z kwiatów języczkowych nagietka lekarskiego (Calendula officinalis L.). Wszystkie badane próbki charakteryzowały się niskimi właściwościami antyoksydacyjnymi. Czas parzenia oraz temperatura wody wpły-wały na zawartość polifenoli i właściwości antyoksydacyjne naparów. Aby uzyskać napar z suszonych kwiatów języczkowych z nagietka o najwyższej zawartości polifenoli, należy parzyć je przez 10 minut, przy użyciu wody o temperaturze 80°C. Najwyższą zdolność do zmiatania rodnika DPPH uzyskał napar sporządzony w najwyższej temperaturze 100°C, po 10 minutach parzenia. Otrzymane wyniki wskazują na potencjalną możliwość wykorzystania tego surowca do produkcji naparów herbacianych.

Twórczość Grigorija Krużkowa jest ze wszech miar godna opisu i popularyzacji. To ceniony i nagradzany rosyjski tłumacz poezji anglojęzycznej, teoretyk przekładu, profesor w Katedrze Teorii i Praktyki Przekładu Rosyjskiego Państwowego Uniwersytetu Humanistycznego w Moskwie. Jest m.in. autorem obszernej antologii przekładów 115 angielskich, irlandzkich i amerykańskich poetów oraz wyboru angielskich i irlandzkich wierszy i bajek. W 2015 roku otrzymał tytuł doktora honoris causa Trinity College w Dublinie. Widzi on pracę tłumacza jako twórczość, która rodząc się z miłości i jedności duchowej z autorem oryginału, może zapewnić temu ostatniemu nieśmiertelność w innych językach. Do tego właśnie nawiązują wyraźnie tytuły jego esejów. Co ciekawe, na polskim gruncie analogiczne wnioski formułuje z wielkim przekonaniem Wiesław Myśliwski, podkreślając, że tłumacz musi stworzyć (nie odtworzyć) dzieło na nowo we własnym języku.
Mistrz-nauczyciel i jego powinności. Szkic z pedeutologii historycznej
Authors: Szulakiewicz Władysława
Published: December 2021

Przedstawione rozważania wpisują się w zakres pedeutologii historycznej. Prezentowany szkic poświęcony jest problemowi mistrza-nauczyciela w kontekście rozwoju nauki, badań naukowych i nauczania. Podjęto w nim próbę opisu powinności jakie musi spełniać osoba, którą można określić mianem mistrza. Uczyniono to na wybranych przykładach mistrzów, zasłużonych dla nauki i nauczania, głównie przedstawicieli historii wychowania i pedagogiki. Ich zasługi polegają na stworzeniu szkół naukowych i rozwoju polskich środowisk naukowych. Na potrzeby zaprezentowania zagadnienia wykorzystano zarówno opracowania, jak i materiały archiwalne oraz literaturę pamiętnikarską. Pomocne były też źródła wywoływane. Wnioski wypływające z analizy źródeł doprowadziły do przekonania, że jednym z najważniejszych cech mistrza-nauczyciela jest rzetelność, przejawiająca się zarówno w dydaktyce uniwersyteckiej, jak i badaniach naukowych. Rzetelność naukowa jest nie tylko wartością w ogóle, ale przede wszystkim powinnością osób, które można nazwać mistrzami. Przy czym należy podkreślić, że artykuł nie pretenduje do miana wyczerpującego studium, jest jedynie zarysem planowanych dalszych badań nad istotą mistrza-nauczyciela i jego znaczenia w dziejach nauki i kultury.
Earth Science Education #6. Lessons Learned: Organizing a Geoscience Outreach Program at the University of Saskatchewan
Authors: Onstad Courtney
Published: December 2021

Geology Outreach at the University of Saskatchewan was initiated during the 2018/19 academic year as a free and informal education opportunity for K–12 educators and their students in Saskatchewan. The program was 100% volunteer-run by undergraduate and graduate students in the Department of Geological Sciences at the University of Saskatchewan. We estimate reaching more than 1000 students in Saskatoon and surrounding areas following two years of outreach offerings. Hands-on activities offered included ‘Rocks and Minerals’, ‘Fossils’, ‘Meteorite Impacts’ and ‘Volcanoes’ and also involved a tour of the Museum of Natural Sciences when completed on campus. The overall intent of these activities was to foster excitement about the Earth Sciences. Typically, Educators who booked our program taught grades 4–7, where the Earth Sciences are strongly represented in Saskatchewan’s science curriculum. Most outreach offerings occurred on the University of Saskatchewan campus, but some were offered remotely at elementary schools and various Girl Guides of Canada events. During the 2019/20 academic year, we booked every outreach event planned for that year within two days and had a waiting list of more than 30 teachers across the province. The demand for geoscience outreach in Saskatchewan is high, and we hope to continue providing engaging, relevant, and fun educational outreach opportunities. University departments across Canada should allocate funds for community and school outreach initiatives and hire science communicators to oversee programs such as this.
“Que a cabsa de no entender la lengua no saben ni entienden cosa alguna”. Actitudes y conflicto lingüístico en moriscos y cristianos viejos en la Castilla del siglo XVI
Authors: Abad Merino Mercedes , Jiménez Alcázar Juan Francisco
Published: December 2021

En la frontera del reino de Granada se generó una situación lingüística conflictiva que vamos a estudiar desde la perspectiva de los hablantes. Analizaremos cuál era la actitud lingüística de cristianos viejos y moriscos frente a la lengua del otro; cómo se muestran juicios y valoraciones sobre ella, o cómo se llegan a extender más allá de los rasgos puramente lingüísticos hasta otras esferas culturales y sociales. Emplearemos principalmente fuentes documentales inéditas, que nos aproximen a esta particular situación histórico-lingüística y que nos permitan obtener información directa sobre la discriminación que ocasiona la diferencia lingüística. Analizaremos el discurso lingüístico, mostrando testimonios que se refieran explícitamente a la lengua de diversas formas.
La biblioteca del I marqués del Cenete (1468-1523) como paradigma del coleccionismo bibliográfico renacentista
Authors: Ferrer del Río Estefania
Published: December 2021

En el presente trabajo analizamos la colección bibliográfica de 653 libros de Rodrigo de Mendoza, I marqués del Cenete, a través del inventario de bienes post mortem que se realizó a partir del 27 de febrero de 1523, tras su óbito. A pesar de que la información que proporciona el notario no es muy detallada, vislumbra suficientes detalles como para conocer las lenguas en las que estaban compuestas las obras, los diferentes autores que podían formar parte de su biblioteca de manera recurrente, sus lecturas más frecuentes y, quizá, preferidas, así como el material de los volúmenes en cuestión y la relación de todos aquellos que adquirieron parcialmente su biblioteca en las almonedas acaecidas entre 1529 y 1535. ¿Podría una biblioteca tan numerosa y exquisita para la época haberse convertido en paradigma del coleccionismo bibliográfico del Renacimiento hispano? Cuestión a la que pretendemos dar respuesta en estas líneas.
La fe de andalusíes y mudéjares a través del "Hajj"
Authors: Rodríguez Plaza Jesús
Published: December 2021

El peregrinaje a La Meca constituye el quinto pilar (u obligación) del Islam, lo que lo convierte en un acontecimiento de gran importancia en la vivencia de la fe islámica. En este artículo nos proponemos analizar cómo lo vivieron dos musulmanes, un almohade y un mudéjar, y profundizar así en la cuestión de la identidad islámica de las comunidades mudéjares que vivieron su fe en minoría frente a la expresión dominante del islam andalusí. Para ello nos serviremos de los relatos de viaje (rihla) de dos peregrinos que representan cada una de estas realidades, el valenciano Ibn Yubayr y el abulense Omar Patún.
Logistic Regression via Excel Spreadsheets: Mechanics, Model Selection, and Relative Predictor Importance
Authors: Brusco Michael
Published: December 2021

Logistic regression is one of the most fundamental tools in predictive analytics. Graduate business analytics students are often familiarized with implementation of logistic regression using Python, R, SPSS, or other software packages. However, an understanding of the underlying maximum likelihood model and the mechanics of estimation are often lacking. This paper describes two Excel workbooks that can be used to enhance conceptual understanding of logistic regression in several respects: (i) by providing a clear formulation and solution of the maximum likelihood estimation problem; (ii) by showing the process for testing the significance of logistic regression coefficients; (iii) by demonstrating different methods for model selection to avoid overfitting, specifically, all possible subsets ordinary least squares regression and l1-regularized logistic regression (lasso); and (iv) by illustrating the measurement of relative predictor importance using all possible subsets.
A transdisciplinary approach to adolescent safeguarding education
Authors: Littler Nadine
Published: December 2021

Background:

Adolescent safeguarding is a key public health issue, which requires a transdisciplinary approach to address the range of safeguarding risks seen within this critical period of development. Aims: The aim of this research study was to explore the need for adolescent safeguarding education within transdisciplinary programmes.

Methods:

A qualitative descriptive study was undertaken with participants studying or teaching on nursing, policing, social work, youth work and teaching programmes at a North-West University in England. Participation involved either the completion of a JISC online questionnaire or an informal interview, the data of which was analysed using thematic analysis.

Findings:

Two key themes were identified in the data; safeguarding education and professional culture, and three subthemes: curriculum content and delivery and professional identity.

Conclusions:

This study has highlighted the need to adopt a life-course (adolescence) and hybrid approach (uniprofessional and transdisciplinary) to safeguarding education in transdisciplinary programmes.
Treating chronic migraines with botulinum toxin
Authors: CHARLSON PAUL
Published: December 2021

Migraine is a common condition that causes significant morbidity. It is often divided into acute and chronic, but there can be overlap between those who have variable frequency acute episodes and those who have chronic migraine with 15 headache-associated days per month. Botulinum toxin is a prophylactic treatment licensed for chronic migraine, where it has been shown to be an effective and safe treatment. It requires approximately 200 units per treatment session, usually at 3-month intervals. The protocols allowing NHS treatment strictly limit its use. Patients may seek this on a private basis, and suitably qualified aesthetic clinicians who are Care Quality Commission-registered could reasonably treat patients.

Objective:

To compare the effectiveness of two commonly used moist dressings, Aquacel and Aquacel Foam (both ConvaTec Ltd., UK), in managing split-thickness skin graft (STSG) donor site wounds.

Method:

Patients undergoing STSG harvesting for reconstruction were eligible for this quasi-experimental study. After reconstruction surgery, the Aquacel (A) or Aquacel Foam (AF) dressings were applied on the donor site wound. The STSG donor site was assessed by two trained research nurses daily. Clinical outcomes including pain on dressing removal, use of intravenous analgesics, signs and symptoms of wound infection, incidence of exudate leakage and percentage healed were recorded in a standardised form. Cost of the dressing change was retrieved from the hospital billing system.

Results:

Of 50 patients recruited, 25 received dressing A and 25 received the AF dressing for their STSG donor site wound. The average pain score on dressing removal was significantly lower in the AF dressing group compared with the A dressing group (0.8±0.8 versus 3.1±1.5, respectively (p=0.04)). Regression analysis demonstrated that compared with dressing A, the AF dressing was associated with a lower average pain score (beta: –2.27, standard error: 0.33; p<0.001), lower likelihood of pro re nata (PRN) intravenous analgesic use (odds ratio (OR)=0.21, 95% confidence interval: 0.06–0.71; p=0.01) and lower likelihood of exudate leakage (OR=0.11, p=0.01). The differences in time to wound healing, infection and cost were not statistically significant between the two groups.

Conclusion:

In this study, the AF dressing demonstrated superior performance in pain response on dressing removal for STSG donor site wounds compared with dressing A. Large-scale randomised controlled trials should be conducted to confirm the findings.
