“…The departure from the social cognitive theory in this aspect of learning reduces the learners' competence to some extent and unless the lecturers have other means of remediating this within the time allotted for paediatric training, learners are likely going to be deficient in some key skills needed for practice as was noted in the study by Rakotz et al [34]. No doubt paediatrics brings with it, the challenge of trying not to inflict more pain on an already sick infant, but the alternative of using mannequins and other gadget may not eventually transmit the needed skills for future practice [27].…”

The Medical and Dental Council of Nigeria (MDCN), the regulatory body for medical practice in Nigeria, provides the benchmark for minimum academic standards (BMAS). While it is expected that there will be differences across schools, the extent of this is unknown and the effect/impact it will have on future medical practice in Nigeria is unknown. This study aimed to evaluate the differences in undergraduate paediatric endocrinology contents across medical schools in southern Nigeria and to understand the factors that influence these differences. Seven paediatric endocrinology lecturers were interviewed, and they filled a questionnaire generated from the themes of the discussion. The themes included the contents of diabetes mellitus lectures, the level of participation lecturers allowed students in emergency room management of DKA, and the assessment methods. Lecture notes on diabetes mellitus (DM) were scored using ISPAD guidelines and the differences were analysed using Student’s T test. The extent to which competence was assessed for students was also provided by the lecturers. Two lecturers had reduced contents in their DM lectures, compared to others, $p = 0.003$. Most lecturers did not consult the MDCN BMAS while preparing their lecture notes. This study highlights the differences in curriculum contents in Southern Nigeria medical schools for endocrinology training in paediatrics, and significant differences methods of training. These differences will hamper the core objectives of human capital development should the trend continue. It is recommended that uniform curriculum template that is acceptable to many to streamline training and medical practice.

“…Most publicly available trainers only exist with adult-size anatomy, whereas this individualized phantom construction can help address the unique challenges of pediatric sizes and abnormal anatomy as. 15 This is especially relevant as size mismatch between recipient and graft causing variation in location and appearance on AP fluoroscopy is mor prevalent in the pediatric population. Additionally, the agar recipe can be modified to reflect a softer surface, seen in newer transplant patients, or a harder surface, seen in patients with septal scarring.…”

Endomyocardial biopsy (EMB) of the right ventricular (RV) septal surface during cardiac catheterization is the standard method to assess cardiac allograft rejection, heart failure, or inflammatory cardiomyopathies. We developed methodology using a three‐dimensional (3D) printed phantom to provide proof of concept for using biplane overlay technology for targeted EMB. A standard bioptome and steerable sheath were used to discern feasibility of biopsy for seven regions of the RV septum guided by 3D overlay. This novel biopsy phantom can help train operators in biopsy techniques, and biplane overlay technology has the potential to advance targeted EMB in transplant and cardiomyopathy populations.

“…Healthy adult and pediatric cardiologists, including trainees, across three institutions volunteered to participate providing they had completed at least 1 week of an electrophysiology rotation demonstrating a basic clinical understanding of cardiac ablation procedures. A pediatric electrophysiology simulator designed to illuminate a bulb when catheter electrode contact is achieved with various targets within the vasculature [17] was set up on a benchtop. The participants were consented and given up to 5 min to become comfortable using the simulator, catheters, and novel torque tool.…”

Background: Cardiac ablation catheters are small in diameter and pose ergonomic challenges that can affect catheter stability. Significant finger dexterity and strength are necessary to maneuver them safely. We evaluated a novel torque tool to reduce muscle activation when manipulating catheters and improve perceived workload of ablation tasks. The objective was to evaluate measurable success, user perception of workload, and muscle usage when completing a simulated ablation task with and without the use of a catheter torque tool. Methods: Cardiology attendings and fellows were fitted with surface electromyographic (EMG) sensors on 6 key muscle groups in the left hand and forearm. A standard ablation catheter was inserted into a pediatric cardiac ablation simulator and subjects navigated the catheter tip to 6 specific electrophysiologic targets, including a 1-min simulated radiofrequency ablation lesion. Time to complete the task, number of attempts required to complete the lesion, and EMG activity normalized to percentage of maximum voluntary contraction were collected throughout the task. The task was completed 4 times, twice with and twice without the torque tool, in semi-randomized order. A NASA Task Load Index survey was completed by the participant at the conclusion of each task. Results: Time to complete the task and number of attempts to create a lesion were not altered by the tool. Subjectively, participants reported a significant decrease in physical demand, effort, and frustration, and a significant increase in performance. Muscle activation was decreased in 4 of 6 muscle groups. Conclusion: The catheter torque tool may improve the perceived workload of cardiac ablation procedures and reduce muscle fatigue caused by manipulating catheters. This may result in improved catheter stability and increased procedural safety
