Abstract PDF PubReader ePub: Background
Procalcitonin (PCT) is a crucial biomarker for diagnosing sepsis and managing antibiotic therapy. This study evaluated the analytical performance and comparability of the Access PCT and Elecsys BRAHMS PCT assays.
Methods
The precision, detection capability, linearity, and reference range of both assays were assessed. A comparative analysis included 182 patient samples categorized into four risk groups to compare the results between Access PCT and Elecsys BRAHMS PCT assays.
Results
The Access PCT assay demonstrated precision within the manufacturer’s threshold, and its detection capabilities were verified. This assay exhibited excellent linearity and appropriate reference intervals. Comparative analysis indicated that the Access PCT assay reported higher overall PCT levels than the Elecsys BRAHMS assay, with high agreement between the assays (κ=0.941). However, the biases varied across different PCT concentration intervals.
Conclusions
Both the Access PCT and Elecsys BRAHMS PCT assays performed robustly with notable concordance but varying biases at different concentration intervals. The observed biases require careful consideration in clinical decision-making, especially when adopting novel assay systems. Standardizing the calibration across different platforms is recommended to improve assay comparability.

The ethics of using artificial intelligence in medical research: Shinae Yu, Sang-Shin Lee, Hyunyong Hwang; Kosin Med J. 2024;39(4):229-237. Published online December 6, 2024; DOI: https://doi.org/10.7180/kmj.24.140

The integration of artificial intelligence (AI) technologies into medical research introduces significant ethical challenges that necessitate the strengthening of ethical frameworks. This review highlights the issues of privacy, bias, accountability, informed consent, and regulatory compliance as central concerns. AI systems, particularly in medical research, may compromise patient data privacy, perpetuate biases if they are trained on nondiverse datasets, and obscure accountability owing to their “black box” nature. Furthermore, the complexity of the role of AI may affect patients’ informed consent, as they may not fully grasp the extent of AI involvement in their care. Compliance with regulations such as the Health Insurance Portability and Accountability Act and General Data Protection Regulation is essential, as they address liability in cases of AI errors. This review advocates a balanced approach to AI autonomy in clinical decisions, the rigorous validation of AI systems, ongoing monitoring, and robust data governance. Engaging diverse stakeholders is crucial for aligning AI development with ethical norms and addressing practical clinical needs. Ultimately, the proactive management of AI’s ethical implications is vital to ensure that its integration into healthcare improves patient outcomes without compromising ethical integrity.

The effectiveness of Moodle's “Lesson” feature in pre-learning about arterial puncture and blood transfusion procedures: Haeyoung Lee, Sang-Shin Lee, Hyunyong Hwang; Kosin Med J. 2023;38(4):278-287. Published online December 29, 2023; DOI: https://doi.org/10.7180/kmj.23.150

Abstract PDF PubReader ePub: Background
This study evaluated the effectiveness of Moodle’s “Lesson” feature as a pre-learning tool for clinical skills among medical students.
Methods
The performance of 69 fourth-year medical students during practical sessions on arterial puncture and blood transfusion was assessed. These students engaged in pre-learning activities via Moodle's “Lesson” feature. We analyzed the survey results to gauge students’ satisfaction and perceived usefulness of the pre-learning approach. Additionally, we compared the performance of the 2023 cohort, which took part in the pre-learning process, with students from 2020 to 2022 who did not have this preparatory component.
Results
Among the students surveyed, data from 59 respondents were analyzed. Satisfaction with the pre-learning segment was high, with a mean satisfaction score of 4.69 (standard deviation [SD]=0.62) and Cronbach’s alpha of 0.918. The tool's perceived usefulness was also rated highly, with a mean score of 4.77 (SD=0.53) and Cronbach’s alpha of 0.956. Students who used the pre-learning tool had a mean score of 84.20 (SD=14.74), whereas those who did not use the tool scored slightly lower, with a mean of 80.40 (SD=13.07); however, this difference was not statistically significant (p=0.196). Nonetheless, the 2023 cohort scores were generally higher across the various percentile measures than those of the 2020–2022 groups.
Conclusions
The pre-learning tool using the “Lesson” feature on Moodle proved useful and satisfactory for students learning clinical procedures. Further research with larger cohorts is required to validate these findings.

New approach to learning medical procedures using a smartphone and the Moodle platform to facilitate assessments and written feedback: Sang-Shin Lee, Haeyoung Lee, Hyunyong Hwang; Kosin Med J. 2022;37(1):75-82. Published online March 25, 2022; DOI: https://doi.org/10.7180/kmj.22.010

Background
To overcome communication obstacles between medical students and trainers, we designed serial learning activities utilizing a smartphone and web-based instruction (WBI) on the Moodle platform to provide clear and retrievable trainer feedback to students on an objective structured clinical examination (OSCE) item.
Methods
We evaluated students’ learning achievement and satisfaction with the new learning tool. A total of 80 fourth-year medical students participated. They installed the Moodle app (the WBI platform) on their smartphones and practiced an endotracheal suction procedure on a medical simulation mannequin while being evaluated by a trainer regarding competence in clinical skills on the smartphone app. Students’ competency was evaluated by comparing the scores between the formative assessment and the summative assessment. The degree of satisfaction and usefulness for the smartphone and WBI system were analyzed.
Results
The means (standard deviations, SDs) of the formative and summative assessments were 8.80 (2.53) and 14.24 (1.97) out of a total of 17 points, respectively, reflecting a statistically significant difference (P<0.05). The degree of satisfaction and perceived usefulness of the smartphone app and WBI system were excellent, with means (SDs) of 4.60 (0.58), and 4.60 (0.65), respectively.
Conclusion
We believe that the learning process using a smartphone and the Moodle platform offers good guidance for OSCE skill development because trainers’ written feedback is recorded online and is retrievable at all times, enabling students to build and maintain competency through frequent feedback review.

Fibromyalgia syndrome (FMS) has chronic widespread pain (CWP) as a core symptom and a variety of associated somatic and psychological symptoms such as fatigue, sleep problems, cognitive disturbances, multiple somatic pain, and depression. FMS is the subject of considerable controversy in the realm of nosology, diagnosis, pathophysiology, and treatment. Moreover, the fact that FMS and mental illness are closely associated with each other might intensify the confusion for the distinction between FMS and mental disorders. This narrative literature review aims to provide the concept, diagnosis, and treatment of FMS from the integrative biopsychosocial and psychosomatic perspective. This article first explains the concepts of FMS as a disease entity of biopsychosocial model, and then summarizes the changes of diagnostic criteria over past three decades, differential diagnosis and comorbidity issue focused on mental illnesses. In addition, an overview of treatment of FMS is presented mainly by arranging the recommendations from the international guidelines which have been developed by four official academic associations.
