METHODS: We herein report, to our knowledge, the first observation on the frequency and nature of GATA1 gene mutations in a cohort of Malaysian children with DS-associated TAM (n = 9) and ML-DS (n = 24) encountered successively over a period of five years at a national referral centre.
RESULTS: Of the 29 patients who underwent GATA1 analysis, GATA1 mutations were observed in 15 (51.7%) patients, including 6 (75.0%) out of 8 patients with TAM, and 9 (42.9%) of 21 patients with ML-DS. All identified mutations were located in exon 2 and the majority were sequence-terminating insertions or deletions (66.7%), including several hitherto unreported mutations (12 out of 15).
CONCLUSION: The low frequency of GATA1 mutations in ML-DS patients is unusual and potentially indicates distinctive genomic events in our patient cohort.
METHODS: Students completed a three-station OSCE and a written self-reflection about their performance. These reflections were coded using a latent pattern content analysis, with categories defined as "doing well (≥ 50% on exam)" and "not doing well (< 50% on exam)" and compared to their actual OSCE exam scores, to determine the degree of alignment.
RESULTS: Two hundred sixty-nine students completed the OSCE and reflection. Students had a low degree of alignment between their self-reflections and actual OSCE performance. Low alignment was overwhelmingly prevalent and significant in high-achieving students with OSCE scores of ≥90%. Most common aspects students reflected on as indicators of performance were finishing on time and communicating effectively. High-achieving students reflected on aspects such as empathy, systematic questioning, and patient teach-back as aspects of their performance.
CONCLUSIONS: Student reflections on exam performance do not align with their actual performance, particularly amongst the high-achieving students. High-achieving students were more aware of the different aspects that affected their performance. To ensure that high-achieving students are aware of their strengths, educators should provide more targeted feedback mechanisms and positive reassurances to help these students become more confident in their decision-making skills.
METHODS: A traditional F2F workshop on hepatitis management was conducted with 364 students in 2021 and was compared with a virtual self-run escape room game called Hepatitiscape™, which was used by 417 students in 2022. The outcomes were final examination and objective structured clinical examination (OSCE) scores for hepatitis stations. An incremental cost-effectiveness ratio was used to compare costs and outcomes. Student perceptions of the delivery of Hepatitiscape™ were also captured using an online questionnaire.
RESULTS: Delivering the hepatitis case workshop via Hepatitiscape™ yielded an additional 4.77% increase in the final examination score and a 21.04% increase in the OSCE score at an additional cost of AUD $4212 in the first year compared with F2F delivery. This equated to an incremental cost-effectiveness ratio of AUD 883 per additional score of final examination and AUD 200 per additional score of OSCE for hepatitis stations. Hepatitiscape™ became cost saving from the second year onward. Student perception data revealed their recall of content was higher owing to the iterative design of the gaming elements.
CONCLUSIONS: Hepatitiscape™ is likely to be a cost-effective strategy to deliver workshops that are routinely delivered F2F to test knowledge-based constructs. In addition, virtual gaming has a logistical advantage over F2F delivery in that it enhances student participation from remote locations and allows for better control and flexibility of content delivery with increasing or decreasing cohort sizes, and can have potential long-term sustainable savings.
METHODS: We conducted a retrospective review of medical and laboratory records in a general paediatric ward of a district hospital in a developing country. Inclusion criteria were all children hospitalised with nasopharyngeal swab taken for Bordetella pertussis. We compared sensitivity and specificity of World Health Organization diagnostic criteria with other clinical characteristics. Polymerase chain reaction Bordetella pertussis was the gold standard used.
RESULTS: Out of 207 eligible admissions, the study retrieved 128 complete records. Approximately half of the children were less than 3 months old. The World Health Organization diagnostic criteria had a low sensitivity (15%), but high specificity (92%). In comparison, combinations that included paroxysmal cough, ill contact and facial congestion had higher sensitivity. Increasing cough duration improved specificity while compromising sensitivity.
CONCLUSION: Several clinical characteristics such as paroxysmal cough, facial congestion and a history of ill contact have potential for early clinical detection. Conventional emphasis on cough duration may hamper early detection.
