Use the right words: evaluating the effect of word choice and word count on quality of narrative feedback in ophthalmology competency-based medical education assessments.

Background: The purpose of this study was to investigate the effect of word choice on the quality of narrative feedback in ophthalmology resident trainee assessments following the introduction of competency-based medical education at Queen's University.

Methods: Assessment data from July 2017-December 2020 were retrieved from Elentra (Integrated Teaching and Learning Platform) and anonymized. Written feedback was assigned a Quality of Assessment for Learning (QuAL) score out of five based on this previously validated rubric.

Trends in female applicants to Canadian ophthalmology residency programs from 1998-2020.

Background: Ophthalmology has historically been a male-dominated specialty. Despite there being a higher proportion of females in Canadian medical schools since the early 2000s, it is unknown if trends in female applicants and those accepted to ophthalmology have followed suit. This study aims to evaluate trends in gender representation of ophthalmology applicants to Canadian residency programs from 1998 to 2020 and to compare those trends to other surgical specialties.

Creating a national breastfeeding and lactation policy for Canadian surgical residents.

Background: Despite known benefits of breastfeeding and challenges medical trainees face lactating at work, research specific to Canadian surgical trainees is lacking. Our objectives were to examine existing breastfeeding and lactation policies, query experiences and opinions of surgical trainees and program directors, and propose a comprehensive policy for programs nation-wide.

Methods: A multi-disciplinary team developed this two-part study.

Virtual patients with substance use disorders in healthcare professional education: a scoping review.

Background And Objective: Virtual patient simulations are cost-effective methods for training health professionals. Yet, this teaching method is rarely used with clinicians who work or plan on working with people with substance use disorders. This scoping review summarizes the current state of the literature concerning virtual substance use disorder patient simulations in health professionals' training and provides suggestions for future directions.

A case study: exploring the impact of 3D printed models on cognitive integration during clinical skills training.

Background: Cognitive integration occurs when trainees make conceptual connections between relevant knowledges and is known to improve learning. While several experimental studies have demonstrated how text and audio-visual instruction can be designed to enhance cognitive integration, clinical skills training in real-world contexts may require alternative educational strategies. Introducing three-dimensional (3D) printed models during clinical skills instruction may offer unique learning opportunities to support cognitive integration.

Evaluating the Podcast as an Equity, Diversity and Inclusion resource: a cross-sectional survey analysis.

Background: Equity-deserving groups are communities marginalized from institutional power by oppressive forces (e.g., racism, sexism, homophobia, ableism).

Resident perceptions of learning challenges in concussion care education.

Background: Resident-focused curricula that support competency acquisition in concussion care are currently lacking. We sought to fill this gap by developing and evaluating Spiral Integrated Curricula (SIC) using the cognitive constructivism paradigm and the Utilization-Focused Evaluation (UFE) framework. The evidence-based curricula consisted of academic half-days (AHDs) and clinics for first- and second-year family medicine residents.

Sport Participation Positively Associated with Balance Confidence and Well-being in Transtibial Amputees.

Transtibial amputation (TTA) is the removal of the lower leg often resulting in pain, mental health issues, and a more sedentary lifestyle that lacks physical activity (PA). Low balance confidence and other factors related to the physical and psychosocial adaptation to amputation could contribute to why people with TTA actively avoid PA. Studies have investigated lower extremity amputations and barriers to PA in general, but none have focused solely on transtibial amputation and its relationship with PA participation and avoidance habits.

Leisure-Time Physical Activity and Motivation in Police Cadets: A Self-Determination Study.

Several studies have highlighted the importance of leisure-time physical activity (LTPA) for the health and performance of law enforcement officers. Nevertheless, a considerable proportion of officers still fail to engage in any LTPA. There is a clear need to identify correlates of physical activity among this specific occupational group to help the design of workplace physical activity interventions.

Long-term outcome in people who use drugs successfully treated for hepatitis C infection with glecaprevir/pibrentasvir.

Background: Several clinical trials, including the recently published the GRAND PLAN study from Vancouver Infectious Diseases Center (VIDC), have demonstrated the efficacy of hepatitis C (HCV) therapy among active drug users, including those facing significant addiction-related and social challenges. In the GRAND PLAN, we documented sustained virological response post-treatment Week12 (SVR12) in 108/117 (92.3 %) individuals (108/111 (mITT) or 97.

Isolation and Identification of Mercury-Dissolved Organic Matter Complexes in Mercury-Humic Acid Suspensions.

Rationale: The complexation with dissolved organic matter (DOM) is a pivotal factor influencing transformations, transport, and bioavailability of mercury (Hg) in aquatic environments. However, identifying these complexes poses a significant challenge because of their low concentrations and the presence of coexisting ions.

Methods: In this study, mercury-dissolved organic matter (Hg-DOM) complexes were isolated through solid-phase extraction (SPE) from Hg-humic acid suspensions, and complexes were putatively identified using ultrahigh resolution Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS).

Late positive potentials elicited by negative self-referential processing predict increases in social anxiety, but not depressive, symptoms from age 11 to age 12.

Social anxiety and depression exacerbate in early adolescence. Maladaptive self-referential processing confers risk for both conditions and can be assessed by the Self-Referent Encoding Task (SRET). Our cross-sectional findings indicated that the SRET-elicited anterior late positive potential (LPP) was uniquely associated with social anxiety symptoms, whereas behavioral SRET scores were uniquely associated with depressive symptoms.

The Type III Secretion System (T3SS) of Escherichia Coli Promotes Atherosclerosis in Type 2 Diabetes Mellitus.

Large-scale studies indicate a strong relationship between the gut microbiome, type 2 diabetes mellitus (T2DM), and atherosclerotic cardiovascular disease (ASCVD). Here, a higher abundance of the type III secretion system (T3SS) virulence factors of Enterobacteriaceae/Escherichia-Shigella in patients with T2DM-related-ASCVD, which correlates with their atherosclerotic stenosis is reported. Overexpression of T3SS via Citrobacter rodentium (CR) infection in Apoe-/- T2DM mice exacerbated atherosclerotic lesion formation and increased gut permeability.

Blended soil amendments: A viable strategy to reduce soluble phosphorus in soils.

Phosphorus (P) loss from soils can contribute significantly toward P enrichment in water bodies, impairing water quality. Application of soil amendments is a viable strategy to decrease soluble P in surface soils. Since soluble P is reduced through different mechanisms that are amendment-specific, blended amendments could be a better approach than single amendment applications; however, very little information is available on blended amendment effects in reducing P loss from soils.

A Randomized Clinical Study Investigating the Stain Removal Efficacy of Two Experimental Dentifrices.

Objective: This study aims to evaluate extrinsic tooth stain removal and whitening efficacy of two experimental dentifrices containing (i) 5% sodium tripolyphosphate (STP)/1% micronized alumina or (ii) 5% STP/1% micronized alumina with abrasive silica (ED2) compared to a regular fluoride dentifrice (RFD) following 8 weeks of use.

Materials And Methods: This was a single-center, randomized, controlled, blind, three-arm, stratified, parallel-group study. Eligible participants underwent clinical assessment of stain on the facial/lingual surfaces of maxillary and mandibular teeth using the modified Lobene stain index (MLSI), and shade of the facial surfaces of the central and lateral maxillary incisors using the VITA Bleachedguide 3D-Master (VITA) shade guide.

Freeze-dried plasma: Hemostasis and biophysical analyses for damage control resuscitation.

Background: Effective hemorrhage protocols prioritize immediate hemostatic resuscitation to manage hemorrhagic shock. Prehospital resuscitation using blood products, such as whole blood or alternatively dried plasma in its absence, has the potential to improve outcomes in hemorrhagic shock patients. However, integrating blood products into prehospital care poses substantial logistical challenges due to issues with storage, transport, and administration in field environments.

Early Initiation of Bundle Sheath Cells During Leaf Development as Visualised by SCARECROW Expression in Dicotyledonous C Plants.

The C type of dicotyledonous plants exhibit a higher density of reticulate veins than the C type, with a nearly 1:1 ratio of mesophyll cells (MCs) to bundle sheath cells (BSCs). To understand how this C-type cell pattern is formed, we identified two SCARECROW (SCR) genes in C Flaveria bidentis, FbSCR1 and FbSCR2, that fully or partially complement the endodermal cell layer-defective phenotype of Arabidopsis scr mutant. We then created FbSCRs promoter β-glucuronidase reporter (GUS) lines of F.
