Reliability of ultrasound ovarian-adnexal reporting and data system amongst less experienced readers before and after training.

Background: The 2018 ovarian-adnexal reporting and data system (O-RADS) guidelines are aimed at providing a system for consistent reports and risk stratification for ovarian lesions found on ultrasound. It provides key characteristics and findings for lesions, a lexicon of descriptors to communicate findings, and risk characterization and associated follow-up recommendation guidelines. However, the O-RADS guidelines have not been validated in North American institutions or amongst less experienced readers.

Artificial Intelligence to Automatically Assess Scan Quality in Hip Ultrasound.

Purpose: Since it is fast, inexpensive and increasingly portable, ultrasound can be used for early detection of Developmental Dysplasia of the Hip (DDH) in infants at point-of-care. However, accurate interpretation\is highly dependent on scan quality. Poor-quality images lead to misdiagnosis, but inexperienced users may not even recognize the deficiencies in the images.

Mosaic mentoring: finding the right mentor for the issue at hand.

Mentoring has a vital role throughout the medical profession. Over the past few years, mentoring has become an area of focus as being an important aspect of radiologists' career starting from the early trainee level. A variety of mentorship strategies have come to the forefront, allowing many avenues for those seeking to engage in mentorship as either a mentee or mentor.

The Online Cross-Country Tour: Evaluation of a Novel Online Series for Canadian Radiology Residency Programs and Future Implications for the Radiology CaRMS Process.

Purpose: The COVID-19 pandemic indefinitely cancelled visiting medical student radiology electives across Canada. In response, the Canadian Association of Radiologists Resident & Fellow Section (CAR RFS) and Medical Student Network (MSN) developed and evaluated an online series for medical students to learn about Canadian radiology residency programs.

Methods: Medical students from any year of training were recruited through the MSN, local radiology interest groups, and social media to attend a 2-week online series of interactive sessions via Zoom with program representatives from Canadian radiology residency programs.

Impact of scan quality on AI assessment of hip dysplasia ultrasound.

Aims: Early diagnosis of developmental dysplasia of the hip (DDH) using ultrasound (US) is safe, effective and inexpensive, but requires high-quality scans. The effect of scan quality on diagnostic accuracy is not well understood, especially as artificial intelligence (AI) begins to automate such diagnosis. In this paper, we developed a 10-point scoring system for reporting DDH US scan quality, evaluated its inter-rater agreement and examined its effect on automated assessment by an AI system-MEDO-Hip.

Impact of COVID-19 on Canadian Radiology Residency Training Programs.

Purpose: The novel coronavirus disease (COVID-19) pandemic has swept the globe, with a domino effect on medical education and training. In this study, we surveyed Canadian radiology residents to understand the impact of the pandemic on their residency training, strategies utilized by the residency programs in mitigating those impacts, and factors important to residents in the selection of educational resources on COVID-19.

Methods: A 10-item questionnaire was distributed to 460 resident members of the Canadian Association of Radiologists.

Radiation Exposure to the Sacroiliac Joint From Low-Dose CT Compared With Radiography.

Objective: The primary objective of this study was to estimate the effective dose delivered to the sacroiliac joint (SIJ) from low-dose (LD) CT compared with that from radiography. Secondary objectives included evaluation of diagnostic quality of LD CT of the SIJ and development of a clinical protocol for LD CT of the SIJ.

Materials And Methods: Data from 36 patients (19 women, 17 men) undergoing LD CT for suspected renal colic were analyzed.

Reliability of 2D and 3D ultrasound for infant hip dysplasia in the hands of novice users.

Purpose: Developmental dysplasia of the hip (DDH) diagnosis by two-dimensional ultrasound (2DUS) can have poor inter-rater reliability. 3D ultrasound (3DUS) may be more reliably performed, particularly by novice users. We compared intra- and inter-rater reliability between expert and novice operators performing 2DUS and 3DUS for DDH.

Exploring the variability in acute glycemic responses to exercise in type 2 diabetes.

Aim: To explore the factors associated with exercise-induced acute capillary glucose (CapBG) changes in individuals with type 2 diabetes (T2D).

Methods: Fifteen individuals with T2D were randomly assigned to energy-matched high intensity interval exercise (HI-IE) and moderate intensity continuous exercise (MI-CE) interventions and performed a designated exercise protocol 5 days per week for 12 weeks. The duration of exercise progressed from 30 to 60 minutes.

Feasibility and preliminary efficacy of high intensity interval training in type 2 diabetes.

Aims: To compare the feasibility of high intensity interval exercise (HI-IE) versus moderate intensity continuous exercise (MI-CE) in patients with type 2 diabetes (T2D), and to investigate the preliminary efficacy of HI-IE and MI-CE for improving glycated hemoglobin A1c (HbA1c) and body composition.

Methods: Individuals with T2D were recruited and randomly assigned to HI-IE and MI-CE. Exercise training was performed 5 days per week for 12 weeks.

Identification of novel antioxidative peptides derived from a thermolytic hydrolysate of ovotransferrin by LC-MS/MS.

Ovotransferrin is a glycoprotein well-known for its iron-binding property. Ovotransferrin was reported to have antioxidative properties, but the presence of antioxidant peptides within the protein has not been reported. The purpose of the study was to characterize the antioxidant peptides within ovotransferrin.
