This essay argues that practical discussions about pedagogy in the field of Victorian studies warrant a regular place in major field-based conferences and journals as well as greater attention in graduate programs at large to maintain our discipline's viability. While conversations about and tools to help with teaching have become more prominent in digital projects like Undisciplining the Victorian Classroom and COVE, these topics continue to be minimized at conferences like NAVSA and are often relegated to special issues of Victorian studies journals. By “defamiliarizing” pedagogy, we ask the field of Victorian studies to reckon with the ways its systems of prestige and recognition sideline teacher-scholars working at teaching-intensive institutions, community colleges, high schools, and minority-serving institutions. We assert that, given the current state of the job market, more space must be dedicated to pedagogical research, and requirements for tenure/promotion need to recognize pedagogy as a viable field of research. Such attention to pedagogy will contribute to efforts to decolonize Victorian studies, attend more deeply to gendered and racialized labor politics, and mobilize for collective action.

OBJECTIVES/GOALS: The goal of this study is to investigate the potential independent relationship between epicardial adipose tissue (EAT) and cardiometabolic health in youth-onset type 2 diabetes (T2D) and explore changes in EAT as a potential mediator of changes in cardiometabolic health in response to vertical sleeve gastrectomy (VSG). METHODS/STUDY POPULATION: We will assess glycemic control, insulin sensitivity and secretion in youth with T2D before and 3 months after VSG. Fasting labs, anthropometrics, and a 4-hour, frequently sampled liquid mixed meal tolerance test (45g carbohydrates, 14g fat, and 14g protein) were performed. Calculations included glucose, insulin, and GLP-1 area under the curve (AUC), Matsuda Index, HOMA-IR, and oral disposition index (DI). These cardiometabolic outcomes will then be assessed for associations between total EAT volume, measured from cardiac MRI. RESULTS/ANTICIPATED RESULTS: Previous studies have shown that individuals with obesity have higher EAT than lean controls, and adults with T2D have even higher EAT than obese controls. Therefore, we anticipate that our participants will have higher volume of EAT than what has been reported in the literature and that they will have worsening cardiometabolic outcomes without MBS. Our anticipated results will include: Weight and BMI, hemoglobin A1c, diabetes medications, Matsuda Index, HOMA-IR, DI, and glucose and insulin AUC during an MMTT. Cardiac MRI's are being analyzed and will give total EAT volume and will be analyzed for correlations with the cardiometabolic outcomes of body composition, aortic stiffness, blood pressure, cardiac structure and function, as well as lipid panel and insulin sensitivity. DISCUSSION/SIGNIFICANCE: This study is the first to specifically assess EAT in adolescents with T2D. The assessment of EAT will be done with gold-standard MRI and correlated with cardiometabolic health assessed by gold-standard methods. Together, the results will give insight into EAT as a potential independent cardiometabolic risk factor in adolescents undergoing VSG.

Cette étude examine l’évolution de la couverture accordée aux enjeux dans la presse écrite durant les campagnes au Québec de 1994 à 2018. Deux constats ressortent de cette étude. On assisterait d'abord à une diversification de l'ordre du jour médiatique s'expliquant notamment par un recul de la question nationale dans l'espace médiatique au profit d'enjeux comme l'environnement et l'immigration. Le recadrage de la question nationale nettement plus axée aujourd'hui sur la dimension identitaire que sur la question du statut politique du Québec est frappant. Ces changements semblent indiquer la montée d'un axe politique libéral-autoritaire dans la province, alors même que l’émergence du multipartisme ouvre la porte à un réalignement politique durable. Ces observations tendent à confirmer la perspective voulant que l'ordre du jour lors d'une campagne résulte de l'interaction entre les médias, les partis et les électeurs et qu'il offre ainsi un reflet adéquat de l’évolution de la dynamique politique dans une société donnée.

Loss of local biodiversity resulting from abrupt environmental change is a significant environmental problem throughout the world. Extinctions of plants are particularly important yet are often overlooked. Drawing from a case in Hawai‘i, a global hotspot for plant and other extinctions, we demonstrate an effort to better understand and determine priorities for the management of an endangered plant (‘Ihi makole or Portulaca sclerocarpa) in the face of rapid and extreme environmental change. Volcanic heat emissions and biological invasions have anecdotally been suggested as possible threats to the species. We integrated P. sclerocarpa outplanting with efforts to collect geological and ecological data to gauge the role of elevated soil temperatures and invasive grasses in driving P. sclerocarpa mortality and population decline. We measured soil temperature, soil depth, surrounding cover and P. sclerocarpa survivorship over three decades. The abundance of wild P. sclerocarpa decreased by 99.7% from the 1990s to 2021. Only 51% of outplantings persisted through 3–4 years. Binomial regression and structural equation modelling revealed that, among the variables we analysed, high soil temperatures were most strongly associated with population decline. Finding the niche where soil temperatures are low enough to allow P. sclerocarpa survival but high enough to limit other agents of P. sclerocarpa mortality may be necessary to increase population growth of this species.

Wasted tires are the great source of fuel and valuable components but could be a cause of environmental and land pollution. This study shows the detailed method for the determination of radiocarbon isotope (14C) concentration in tires and their pyrolysis products. Samples are taken from truck and passenger car tires in the form of shredded rubber, pyrolysis oil and recovered carbon black. Liquid scintillation counting (LSC) and accelerator mass spectrometry (AMS) techniques were used for the investigation at Gliwice Radiocarbon and Mass Spectrometry Laboratory, and National Laboratory for Age Determination, Trondheim, Norway. The results are in good agreement. Radiocarbon concentration of the rubber varies significantly because of its complex structure and composition within the tires. The 14C concentration values were found to be higher in pyrolytic oil compared to rubber, and greater in truck tires rather than car tires.

Background: A female carrying the common MERRF mitochondrial DNA A8344G mutation had multiple symmetric lipomatosis (MSL) as the primary disease manifestation. Methods: Case report of a mitochondrial disease patient treating her severe lipomas by lifestyle modifications including a modified ketogenic diet. Results: The patient required lipoma reduction surgery after a rapid rate of lipoma progression. Following a difficult recovery, the patient independently researched an alternative therapy for her disease. The intervention was multi-faceted (dietary, physical activity, meditation) and progressive over two years. A carbohydrate reduced (5–10% of calories) modified ketogenic diet was a major part of the treatment owing to its incidental success in MSL management in her brother for management of glioblastoma multiforme. The outcome of her intervention was positive: weight loss, lipoma size reduction, improvement in physical activity/strength, laboratory markers of insulin resistance, and sense of well including a return to full time work. Conclusions: A potential non-surgical therapy for mitochondrial disease associated MSL appears feasible over the short term. The success of the lifestyle intervention in MSL therapy is unprecedented and, importantly, was fully patient initiated. This novel therapy provides potential insight into the mechanism of MSL exacerbation: suggesting insulin resistance or other lifestyle modifiable factors as mediators of disease progression.

Following public debates on the topic of trust in Quebec, this article examines the alleged social capital differential between Quebec and the rest of Canada. The literature has found lower levels of generalized trust in Quebec, but explanations offered are diverse and conjectural, with historical, sociological and political factors all in contention. We test contextual and compositional influences, including cohort differences, language and linguistic ability, religion, ethnicity, and neighbourhood-level measures of diversity, using pooled cross-sectional data from the Canadian General Social Survey (2003, 2008 and 2013) linked with precise measures of neighbourhood-level ethnic and linguistic diversity drawn from the Canadian census. We identify those Quebecers who have low levels of trust and those who more closely resemble their counterparts in the rest of Canada. We find that individual linguistic ability and linguistic heterogeneity of the neighbourhood are important correlates of trust and that among francophone populations, social distrust is found most in unilingual homogenous communities.

Older persons experiencing a longer length of stay (LOS) or delayed discharge (DD) may see a decline in their health and well-being, generating significant costs. This review aimed to identify evidence on the impact of cognitive impairment (CI) on acute care hospital LOS/DD. A scoping review of studies examining the association between CI and LOS/DD was performed. We searched six databases; two reviewers independently screened references until November 2019. A narrative synthesis was used to answer the research question; 58 studies were included of which 33 found a positive association between CI and LOS or DD, 8 studies had mixed results, 3 found an inverse relationship, and 14 showed an indirect link between CI-related syndromes and LOS/DD. Thus, cognitive impairment seemed to be frequently associated with increased LOS/DD. Future research should consider CI together with other risks for LOS/DD and also focus on explaining the association between the two.

The radiocarbon (14C) calibration curve so far contains annually resolved data only for a short period of time. With accelerator mass spectrometry (AMS) matching the precision of decay counting, it is now possible to efficiently produce large datasets of annual resolution for calibration purposes using small amounts of wood. The radiocarbon intercomparison on single-year tree-ring samples presented here is the first to investigate specifically possible offsets between AMS laboratories at high precision. The results show that AMS laboratories are capable of measuring samples of Holocene age with an accuracy and precision that is comparable or even goes beyond what is possible with decay counting, even though they require a thousand times less wood. It also shows that not all AMS laboratories always produce results that are consistent with their stated uncertainties. The long-term benefits of studies of this kind are more accurate radiocarbon measurements with, in the future, better quantified uncertainties.

The extent to which citizens comply with newly enacted public health measures such as social distancing or lockdowns strongly affects the propagation of the virus and the number of deaths from COVID-19. It is however very difficult to identify non-compliance through survey research because claiming to follow the rules is socially desirable. Using three survey experiments, we examine the efficacy of different ‘face-saving’ questions that aim to reduce social desirability in the measurement of compliance with public health measures. Our treatments soften the social norm of compliance by way of a short preamble in combination with a guilty-free answer choice making it easier for respondents to admit non-compliance. We find that self-reported non-compliance increases by up to +11 percentage points when making use of a face-saving question. Considering the current context and the importance of measuring non-compliance, we argue that researchers around the world should adopt our most efficient face-saving question.

Following the previous article, here we describe the first field demonstration of the ELVIS system, performed at Newport Beach, CA. We examined ocean water to detect microorganisms using the combined holographic and light-field fluorescence microscope and successfully detected both eukaryotes and prokaryotes. The shared field of view provided simultaneous bright-field (amplitude), phase, and fluorescence information from both chlorophyll autofluorescence and acridine orange staining. The entire process was performed in a nearly autonomous manner using a specifically designed sample processing unit (SPU) and custom acquisition software. We also discuss improvements to the system made after the field test that will make it more broadly useful to other types of fluorophores and samples.

Introduction: This study aims to evaluate the accuracy of the Échelle québécoise de triage préhospitalier en traumatologie (EQTPT) to identify patients who will need urgent and specialized trauma care in the La Capitale-Nationale region, province of Quebec. Methods: A detailed review of prehospital and in-hospital medical charts was conducted for a sample of patients transported following a trauma by ambulance to one of the five CHU de Quebec's emergency departments (ED) between November 2016 and March 2017. Data related to the trauma mechanism, population, injuries sustained, diagnosis, intervention and patient outcomes were extracted. The study primary outcome was the use of at least one urgent and specialized trauma care defined as: admission to the intensive care unit (ICU), urgent surgery within less than 24 hours after arrival (excluding orthopedic surgery for one limb only), intubation in ED, angioembolization within 24 hours after ED arrival, activation of a massive transfusion protocol in the ED. Also, patients who died secondary to their trauma were also considered as requiring urgent care. Results: 902 patients were included. The mean age (SD) was 59 (28.5) years old, 494 (54.8%) were female. The main trauma mechanisms were falls (592 (65.6%)) followed by motor vehicle accident (201 (22%)). 367 (40.7%) patients were transported directly to the tertiary trauma centre from the field. 231 (25.6%) patients had at least one criteria included in the steps 1, 2 or 3 of the EQTPT. Subsequently, most patients (649 (71.9%) were discharged home from the ED while 177 (19.6%) patients were admitted to the hospital. 82 (9.1%) patients required urgent and specialized trauma care. Of these 82 patients, 27 patients (32%) were identified in step 1 of the protocol, 12 patients (14.6%) in step 2, 5 patients (6.1%) in step 3, 13 patients (15.9%) in step 4 and 2 patients (2.4%) in step 5 while 23 (28.0%) patients were not identified by any steps of the EQTPT protocol. Therefore, 44 (53.6%) of the patients requiring urgent and specialized trauma care were identified by the criteria proposed in the steps 1, 2 or 3. Conclusion: In this retrospective cohort study, the EQTPT was insensitive to identify trauma patients who will need prompt and complex trauma management. Studies are required to determine the factors that could help improve its accuracy.

Introduction: Suicidal thoughts and self-harm are disproportionately prevalent among older adults but are frequently overlooked by emergency physicians. Objective: This study aims to explore the characteristics of older adults visiting the ED for suicidal thoughts or voluntary intoxications. Methods: All older adults (□ 65 years old) who visited one of the five CHU de Quebec’ EDs in 2016 were eligible. The medical charts of patients who reported suicidal thoughts or intoxication in triage or received a relevant discharge diagnosis were reviewed. Involuntary intoxications were excluded. Descriptive statistics were used to present the results. Results: Results: A total of 478 ED visits were identified, of which 332 ED visits (n= 279 patients) were included. The mean age of the ED cohort was 72.6 (standard deviation 6.8) years old and 41.6% were female. Mood disorders (41.2%) and alcoholism (40.5%) were common. Most included patients had a diagnosis of voluntary intoxication (73.2%), including two suicides (0.6%). Following 109 ED visits (30.0%), patients were referred for a mental health assessment. Half of all ED visits resulted in a discharge by the emergency physician (50.0%), while 27.4% were admitted for in-patient care. In the subsequent year (2017), 38.4% returned to the ED for suicidal ideations or self-harm of which 7.9% attended the ED □ 5 times. Conclusion: ED visits for suicidal thoughts and voluntary intoxication in older adults are more common among men with known mood disorders or alcoholism. Referral for a mental health assessment is inconsistent. ED-initiated interventions designed for this population are needed.

Introduction: Trauma care is highly complex and prone to medical errors. Accordingly, several studies have identified adverse events and conditions leading to potentially preventable or preventable deaths. Depending on the availability of specialized trauma care and the trauma system organization, between 10 and 30% of trauma-related deaths worldwide could be preventable if optimal care was promptly delivered. This narrative review aims to identify the main determinants and areas for improvements associated with potentially preventable trauma mortality. Methods: A literature review was performed using Medline, Embase and Cochrane Central Register of Controlled Trials from 1990 to a maximum of 6 months before submission for publication. Experimental or observational studies that have assessed determinants and areas for improvements that are associated with trauma death preventability were considered for inclusion. Two researchers independently selected eligible studies and extracted the relevant data. The main areas for improvements were classified using the Joint Commission on Accreditation of Healthcare Organizations patient event taxonomy. No statistical analyses were performed given the data heterogeneity. Results: From the 3647 individual titles obtained by the search strategy, a total of 37 studies were included. Each study included between 72 and 35311 trauma patients who had sustained mostly blunt trauma, frequently following a fall or a motor vehicle accident. Preventability assessment was performed for 17 to 2081 patients using either a single expert assessment (n = 2, 5,4%) or an expert panel review (n = 35, 94.6%). The definition of preventability and the taxonomy used varied greatly between the studies. The rate of potentially preventable or preventable death ranged from 2.4% to 76.5%. The most frequently reported areas for improvement were treatment delay, diagnosis accuracy to avoid missed or incorrect diagnosis and adverse events associated with the initial procedures performed. The risk of bias of the included studies was high for 32 studies because of the retrospective design and the panel review preventability assessment. Conclusion: Deaths occurring after a trauma remain often preventable. Included studies have used unstandardized definitions of a preventable death and various methodologies to perform the preventability assessment. The proportion of preventable or potentially preventable death reported in each study ranged from 2.4% to 76.5%. Delayed treatment, missed or incorrect initial diagnosis and adverse events following a procedure were commonly associated with preventable trauma deaths and could be targeted to develop quality improvement and monitoring projects.

This is the first of two articles on the Extant Life Volumetric Imaging System (ELVIS) describing a combined digital holographic microscope (DHM) and a fluorescence light-field microscope (FLFM). The instrument is modular and robust enough for field use. Each mode uses its own illumination source and camera, but both microscopes share a common objective lens and sample viewing chamber. This allows correlative volumetric imaging in amplitude, quantitative phase, and fluorescence modes. A detailed schematic and parts list is presented, as well as links to open-source software packages for data acquisition and analysis that permits interested researchers to duplicate the design. Instrument performance is quantified using test targets and beads. In the second article on ELVIS, to be published in the next issue of Microscopy Today, analysis of data from field tests and images of microorganisms will be presented.
