Association Between In-Training Exam Scores and Clinical Exposure During the COVID-19 Pandemic.

Background: We sought to evaluate changes in In-Training Examination (ITE) scores and associations with clinical work during the COVID-19 pandemic. We hypothesized that residents saw a decrease in clinical encounters during the pandemic and that this would be associated with smaller gains in ITE scores.

Methods: We compared ITE score changes with data on patient notes for three classes of pediatric residents at four residency programs: one not exposed to the pandemic during their intern year who entered residency in 2018, one partially exposed to COVID-19 in March of their intern year (2019-2020), and one that was fully exposed to the pandemic, starting residency in June of 2020.

Evaluating Ultrasonicator Performance for Cyanobacteria Management at Freshwater Sources.

Algal blooms consisting of potentially toxic cyanobacteria are a growing source water management challenge faced by water utilities globally. Commercially available sonication devices are designed to mitigate this challenge by targeting cyanobacteria-specific cellular features and aim to inhibit cyanobacterial growth within water bodies. There is limited available literature evaluating this technology; therefore, a sonication trial was conducted in a drinking water reservoir within regional Victoria, Australia across an 18-month period using one device.

Geographic clustering of travel-acquired infections in Ontario, Canada, 2008-2020.

As the frequency of international travel increases, more individuals are at risk of travel-acquired infections (TAIs). In this ecological study of over 170,000 unique tests from Public Health Ontario's laboratory, we reviewed all laboratory-reported cases of malaria, dengue, chikungunya, and enteric fever in Ontario, Canada between 2008-2020 to identify high-resolution geographical clusters for potential targeted pre-travel prevention. Smoothed standardized incidence ratios (SIRs) and 95% posterior credible intervals (CIs) were estimated using a spatial Bayesian hierarchical model.

Comparison of model predictions of typhoid conjugate vaccine public health impact and cost-effectiveness.

Models are useful to inform policy decisions on typhoid conjugate vaccine (TCV) deployment in endemic settings. However, methodological choices can influence model-predicted outcomes. To provide robust estimates for the potential public health impact of TCVs that account for structural model differences, we compared four dynamic and one static mathematical model of typhoid transmission and vaccine impact.

Educational roles impact burnout in paediatric undergraduate medical educators.

Background: Physician burnout impacts all levels of medical education and has a relatively unknown impact on those responsible for medical student education, particularly in paediatrics. This study examines the prevalence of burnout among paediatric undergraduate medical educators and explores the impact of roles in medical education on medical educator burnout.

Methods: This cross-sectional mixed-methods study utilised a binational survey of paediatricians involved in undergraduate medical education.

Nanostructuring with Surfactants: The Self-Assembly of a New Poly(thiophene-phenylene) Conjugated Polymer Bearing Azacrown Ether Pendant Groups.

We report the synthesis of a new conjugated polymer bearing crown ether moieties, poly[((1-aza-[18]crown-6)carbamido)thiophene-2,5-diyl--1,4-phenylene] (BG2). In water, BG2 forms a dispersion with a slightly cloudy appearance. We have studied the effect of adding surfactants, with different polar head groups, on these polymer-polymer aggregates.

The utility of a maximum entropy species distribution model for Ixodes scapularis in predicting the public health risk of Lyme disease in Ontario, Canada.

Lyme disease is an emerging public health threat in Ontario, Canada due to ongoing range expansion of the tick vector, Ixodes scapularis. Tick density is an important predictor of human Lyme disease risk and is typically measured using active tick surveillance via drag sampling, which is time and resource-intensive. New cost-effective tools are needed to augment current surveillance activities.

Clinical Decision Support Tool for Elevated Pediatric Blood Pressures.

Under-diagnosis of pediatric hypertension remains pervasive due to difficulty recognizing elevated systolic blood pressures (SBPs). We performed a retrospective review comparing recognition of and response to elevated SBPs ≥95th percentile before and after development of a clinical decision support tool (CDST) in an academic pediatric system. Of 44,351 encounters, 477 had elevated SBPs with documented recognition of an elevated SBP in 17.

Complexes of In(III) with 8-hydroxyquinoline-5-sulfonate in solution: structural studies and the effect of cationic surfactants on the photophysical behaviour.

Following previous studies on the complexation in aqueous solutions of 8-hydroxyquinoline-5-sulfonate (8-HQS) with the trivalent metal ions, Al(III) and Ga(III) and various other metal ions, using multinuclear NMR, DFT calculations, UV-vis absorption and luminescence techniques, we have extended our studies on 8-HQS complexation to the trivalent metal ion In(III). The study combines the high sensitivity of luminescence techniques and the selectivity of multinuclear NMR spectroscopy with the structural details accessible through DFT calculations, and aims to obtain a complete understanding of the complexation between the In metal ion and 8-HQS, and how this influences the luminescence behaviour. A full speciation study has been performed and, as has been reported for the complexes of 8-hydroxyquinoline (8-HQ), the dominant complexes of 8-HQS with In(III) show marked differences in the complexation behaviour when compared with the equivalent complexes with the other group 13 cations Al(III) and Ga(III).

Clinical Considerations for Routine Auditory and Vestibular Monitoring in Patients With Cystic Fibrosis.

Purpose Specific classes of antibiotics, such as aminoglycosides, have well-established adverse events producing permanent hearing loss, tinnitus, and balance and/or vestibular problems (i.e., ototoxicity).

Factors associated with complex oral treatment device usage in patients with head and neck cancer.

Purpose: The objective was to identify clinical and epidemiological factors associated with utilization of a complex oral treatment device (COTD), which may decrease toxicity in patients undergoing radiation therapy for head and neck cancer (HNC).

Materials And Methods: We retrospectively reviewed data from 1992 to 2013 in the Surveillance, Epidemiology, and End Results (SEER)-Medicare databases to analyze COTD usage during intensity-modulated radiation therapy (IMRT) for patients diagnosed with cancer of the tongue, floor of mouth, nasopharynx, tonsil, or oropharynx. Patients with a radiation simulation and complex treatment device code within 4 weeks before the first IMRT claim were identified as meeting COTD usage criteria.

Parent Preferences for Neonatal Intensive Care Unit Physician Attire: A Cross-Sectional Study.

Objective: Physician attire may influence the parent-provider relationship. Previous studies in adult and outpatient pediatrics showed that formal attire with a white coat was preferred. We aimed to describe parent preferences for physician attire in the neonatal intensive care unit (NICU).

Speaker Introductions at Grand Rounds: Differences in Formality of Address by Gender and Specialty.

Despite increasing representation of women in medicine, gender bias remains pervasive. The authors sought to evaluate speaker introductions by gender in the grand rounds of multiple specialties at a large academic institution to understand the cultural context of this behavior and identify predictors of formality. The authors reviewed grand rounds recordings of speakers with doctorates presenting to the departments of family medicine, general surgery, internal medicine, obstetrics and gynecology, and pediatrics at one institution from 2014 to 2019.

Method The traditional Valsalva-induced nystagmus test is described, followed by a new method for assessment of superior semicircular dehiscence conducted by laying the patient supine during testing. A case study is presented to illustrate this new testing technique known as the Supine Superior Semicircular Canal Dehiscence Test.

Singlet and Triplet State Properties and Singlet Oxygen Yield of an Amino-Acyl-Quinoxalinone Yellow Dye.

Amino-acyl-quinoxalinone yellow dyes are cyclised analogues of the yellow azomethine dyes developed for, and still used in, silver halide colour photography. Unlike image azomethine dyes, which are rapidly deactivated in their excited states by torsion about the azomethine bond, amino-acyl-quinoxalinone dyes have an interesting photophysics because torsion is not possible due to their cyclised structure. We report results from studies on singlet and triplet state properties, and singlet oxygen yields, of the yellow dye, 7-diethylamino-3-(2,2-dimethyl-propionyl)-5-methyl-1-phenyl-1H-quinoxalin-2-one, in polar and nonpolar solvents.

Removal of Imidacloprid from Water by Microalgae Nannochloropsis sp. and Its Determination by a Validated RP-HPLC Method.

The large-scale use of pesticides is one of the main causes of the dramatic degradation of our environment. Pesticides such as imidacloprid (IMID) have been linked to declines in bee health and toxicity to other beneficial insects. They pose a threat to human health due to their persistence in the environment and accumulation in the food chain.
