Educational evaluation involves data collection and the analysis of various education-related factors to make decisions that improve educational quality. Systematic educational evaluation is essential for enhancing the quality of education. This study reports a case of student-conducted process evaluation of a medical school’s student support system and the procedure for devising improvement plans. Sixteen Inje University College of Medicine students participated in the Education Evaluation Committee (IUCM-EEC) to understand the educational improvement process as learners and actively achieve improvement. The Quality Improvement Committee of the Inje University College of Medicine (IUCM-QIC) decided to reform its student support system based on a previous educational evaluation in 2019. The evaluation of the student support system was conducted for 10 months in 2021 by the student subcommittee, under the guidance of the IUCM-EEC. The CIPP (context-input-process-product) evaluation model was used for a systematic evaluation. Accordingly, the subcommittee developed evaluation criteria and indicators, and analyzed relevant data collected from surveys and the previous literature. For further recommendations and revision ideas, the student subcommittee members interviewed faculty members from six other medical schools and also conducted a focus group interview with the dean and vice deans of IUCM. Finally, the student subcommittee submitted a report to the IUCM-QIC. Communication with various stakeholders is essential for a successful evaluation process. In this case, students, as key stakeholders in education, evaluated the student support system. Their active participation helped improve their understanding of the evaluation process.

Purpose:
Alpha-fetoprotein (AFP) is a prognostic marker for hepatocellular carcinoma (HCC). We investigated the prognostic value of AFP levels in patients who achieved complete response (CR) to transarterial chemoembolization (TACE) for HCC.
Materials and Methods:
Between 2005 and 2018, 890 patients with HCC who achieved a CR to TACE were recruited. An AFP responder was defined as a patient who showed elevated levels of AFP (>10 ng/mL) during TACE, but showed normalization or a >50% reduction in AFP levels after achieving a CR.
Results:
Among the recruited patients, 569 (63.9%) with naïve HCC and 321 (36.1%) with recurrent HCC after complete resection were treated. Before TACE, 305 (34.3%) patients had multiple tumors, 219 (24.6%) had a maximal tumor size >3 cm, and 22 (2.5%) had portal vein tumor thrombosis. The median AFP level after achieving a CR was 6.36 ng/mL. After a CR, 473 (53.1%) patients experienced recurrence, and 417 (46.9%) died [median progression-free survival (PFS) and overall survival (OS) of 16.3 and 62.8 months, respectively]. High AFP levels at CR (>20 ng/mL) were independently associated with a shorter PFS [hazard ratio (HR)=1.403] and OS (HR=1.284), together with tumor multiplicity at TACE (HR=1.518 and 1.666, respectively). AFP non-responders at CR (76.2%, n=359 of 471) showed a shorter PFS (median 10.5 months vs. 15.5 months, HR=1.375) and OS (median 41.4 months vs. 61.8 months, HR=1.424) than AFP responders (all p=0.001).
Conclusion
High AFP levels and AFP non-responders were independently associated with poor outcomes after TACE. AFP holds clinical implications for detailed risk stratification upon achieving a CR after TACE.

Background/Aims:
Besifovir dipivoxil maleate (BSV), an acyclic nucleotide phosphonate, shows potent antiviral activity against hepatitis B virus. Our previous 48-week trial revealed that BSV has comparable antiviral efficacy to tenofovir disoproxil fumarate (TDF) and better safety profiles in terms of improved renal and bone safety. This extension study evaluated the prolonged efficacy and safety of BSV in treatment-naive chronic hepatitis B patients.
Methods:
Patients continued to participate in an open-label BSV study after an initial 48-week double-blind comparison of BSV and TDF treatment. The antiviral efficacy and drug safety was evaluated up to 192 weeks in two groups: patients continuing BSV treatment (BSV-BSV) and patients switching from TDF to BSV after 48 weeks (TDF-BSV).
Results:
Among 197 patients receiving randomized treatments, 170 (86%) entered the open-label phase and 152 (77%) entered the 192-week extension study. Virological response rates over 192 weeks were 92.50% and 93.06% in the BSV-BSV and TDF-BSV groups, respectively (P=0.90). Hepatitis B envelop antigen seroconversion and alanine aminotransferase normalization rates were similar between the groups (P=0.75 and P=0.36, respectively). There were no drug-resistant mutations to BSV. Bone mineral density and renal function were well preserved in the BSV-BSV group, whereas these initially worsened then recovered after switching therapy in the TDF-BSV group.
Conclusions
BSV maintained potent antiviral efficacy after 192 weeks and showed no evidence of drug resistance. BSV was safe, well tolerated, and effective in patients who switched from TDF to BSV. Trial Registration Number: NCT01937806 (date: 10 Sep 2013).

BACKGROUND: Topical tacrolimus is an effective anti-inflammatory therapy for acute and chronic states of atopic dermatitis (AD) in both adults and children. Topical tacrolimus has particular use at sensitive areas such as the face, anogenitals, and skin folds of neck and extremities. However, many AD patients also experience aggravated symptoms on trunk. OBJECTIVE: The aim of this study was to investigate the efficacy and safety of topical tacrolimus for AD patients with truncal lesions. METHODS: AD patients with truncal lesions who were aged ≥2 years were recruited from 20 centres in Korea. They received treatment with topical tacrolimus ointment twice daily during 4 weeks. The primary end point was change of the local eczema area and severity index (EASI) of the trunk from baseline to day 28. The secondary end points were changes in the patient global assessment (PGA) score and itch visual analogue scale (VAS) score of the trunk between baseline and day 28. RESULTS: Two hundred and ninety-one patients were recruited, and 176 patients completed the full 4-week treatment course. By the end of the treatment, the mean local EASI of the trunk (2.2±4.71) was significantly decreased from that at baseline (4.71±4.03, p < 0.001). PGA (1.71±1.15) and itch VAS score of the trunk (2.61±2.19) on day 28 were also profoundly decreased compared with the baseline (2.96±1.07 and 5.15±2.47, respectively). No serious adverse events were observed during the study period. CONCLUSION: Topical tacrolimus is an effective and safe therapy for truncal lesions in AD patients.

BACKGROUND: Psoriasis is an immune-mediated, chronic inflammatory disease affecting multiple aspects of patients' lives. Its epidemiology varies regionally; however, nationwide epidemiologic data on psoriasis depicting profile of Korean patients has not been available to date. OBJECTIVE: To understand nationwide epidemiologic characteristics and clinical features of adult patients with psoriasis visited university hospitals in Korea. METHODS: This multicenter, non-interventional, cross-sectional study recruited 1,278 adult patients with psoriasis across 25 centers in Korea in 2013. Various clinical data including PASI, BSA, DLQI, SF-36 and PASE were collected. RESULTS: A total of 1,260 patients completed the study (male:female=1.47:1). The mean age was 47.0 years with a distribution mostly in the 50s (24.9%). Early onset (<40 years) of psoriasis accounted for 53.9% of patients. The mean disease duration was 109.2 months; mean body mass index was 23.9 kg/m²; and 12.7% of patients had a family history of psoriasis. Plaque and guttate types of psoriasis accounted for 85.8% and 8.4%, respectively. Patients with PASI ≥10 accounted for 24.9%; patients with body surface area ≥10 were 45.9%. Patients with DLQI ≥6 accounted for 78.8%. Between PASI <10 and PASI ≥10 groups, significant difference was noted in age at diagnosis, disease duration, blood pressure, waist circumference of female, and treatment experiences with phototherapy, systemic agents, and biologics. CONCLUSION: This was the first nationwide epidemiologic study of patients with psoriasis in Korea and provides an overview of the epidemiologic characteristics and clinical profiles of this patient population.

OBJECTIVE: Objective To evaluate the prevalence of generalized joint hypermobility (GJH) in healthy female Koreans and to determine whether the degree of GJH differs between children and adults. METHODS: Two groups of females were enrolled, a group of girls from an elementary school (n=404) and women from a call center (n=266). GJH was diagnosed using the Beighton score, which is composed of an evaluation of bilateral knees, elbows, thumbs, and fifth fingers as well as thoracolumbar joint. The GJH and localized hypermobility of each joint was compared between the two groups, and the pattern of hypermobility according to age and dominant hand was investigated. RESULTS: Total prevalence of GJH was 50.0% (335/750), and it was more frequently observed in the group of girls (58.9%, 238/404) than women (36.5%, 97/266). The degree of GJH expressed in terms of Beighton score was inversely correlated with age (p<0.05). Significant differences in localized hypermobility of the thumb and fifth finger were found between the two groups and were postulated as the cause for the decline in GJH with age. The pattern of decreased mobility proportional to aging differed between the two joints. Decreased mobility occurred equally on both sides of the thumb but was biased toward the fifth finger of the dominant side (mostly the right). CONCLUSION: The female Koreans appeared to have a high prevalence of GJH. The incidence of GJH decreased as age increased as a result of decreased mobility of the fifth finger on the dominant side.

Korean Journal of Urology 2012;53(3):189-193
PURPOSE: To evaluate the correlation between lower urinary tract symptoms (LUTS) and premature ejaculation (PE) in Korean men older than 40 years. MATERIALS AND METHODS: In total, 258 men older than 40 years completed the International Prostate Symptom Score (IPSS; total score, storage symptoms [ST], and voiding symptoms [VD]), a 5-item version of the International Index of Erectile Function (IIEF-5), and the Premature Ejaculation Diagnostic Tool (PEDT). The study examined the relationship between LUTS and PE. In the PEDT, PE is defined as a score > or =11. RESULTS: The prevalence of PE was 29.1% with the PEDT versus a self-reported value of 49.5%. The prevalence of PE was 30.9% in 40 to 59-year-old men (21.3%) and 28.1% in 60 to 79 year-old men (78.7%). In men 40 to 59 and 60 to 79 years old, the mean PEDT, IPSS, and IIEF-5 scores were 8.65 and 7.88, 13.5 and 12.38, and 15.83 and 13.69, respectively. No significant correlations were observed between the total and subscale scores of the IPSS (p=0.204) and the PEDT (p=0.309) with increasing age, whereas a significant negative correlation was detected between the IIEF-5 and age (p=0.002). The PEDT score was significantly correlated with the IPSS-ST (r=0.326, p<0.001), IPSS-VD (r=0.183, p=0.005), IPSS-total (r=0.310, p<0.001), and IIEF-5 total (r=-0.248, p<0.001). CONCLUSIONS: LUTS, especially storage symptoms, were related to PE. In elderly men, control of both erectile dysfunction and LUTS may play an important role in managing PE.

BACKGROUND: Food exchange lists are one of the main methods of nutritional education. However, Korean food exchange lists have not been revised since 1994. Therefore, we surveyed the opinions of diabetes educators and patients with diabetes regarding the need for revision of the current food exchange lists. METHODS: For two weeks beginning on 10 March 2008, a 12-item questionnaire regarding the opinion and need for revision of the current food exchange lists was e-mailed to diabetes educators nationwide. Another 15-question survey was administered to patients with diabetes in 13 hospitals located in the Seoul and Gyeonggi regions of Korea. RESULTS: We obtained survey responses from 101 diabetes educators and 209 patients; 65 (64.3%) of the educators answered that the current food exchange lists should be revised. The items that needed revision were the glycemic index, addition of new foods and reaffirmation of exchange standard amounts. The patients demanded specific education about choosing appropriate foods, a balanced meal plan, proper snacks, and dining intake. CONCLUSION: Our survey results demonstrate the need to revise the Korean food exchange lists. This process should focus on glycemic index, the addition of new foods and reconfirmation of one exchange reference unit.
