ABSTRACT
Purpose@#The decision to enroll in medical school is largely influenced by extrinsic motivation factors. It is necessary to explore the factors that affect pre-med students’ motivation to enter medical school and their college adjustment, and to develop measures to help them adjust. @*Methods@#A total of 407 pre-med students were surveyed regarding their motivation to enter medical school, fear of failure, and college adjustment. We analyzed the latent profiles of extrinsic motivation factors using latent profile analysis. One-way analysis of variance was conducted to examine the differences in fear of failure and adaptation to university life according to the latent groups. @*Results@#After analyzing the latent profiles of entrance motivation, three latent profiles were selected. They were divided into high, medium, and low extrinsic motivation groups. Three profiles scored the highest on job security, followed by good grades and social status. Sophomores were more likely to be high extrinsic motivators than freshmen were. Fear of failure was high in the group with high extrinsic motivation, and adaptation to college life was highest in the group with low extrinsic motivation. @*Conclusion@#Job security was the most important extrinsic motivator for entering medical school, and extrinsic entrance motivation influenced fear of failure and college adjustment. Given the high level of extrinsic motivation among medical students, it is meaningful to analyze the extrinsic motivation profile of entering medical students and how it affects failure motivation and college adjustment.
ABSTRACT
Purpose@#The purpose of this study was to examine perceptions of global health education (GHE) among medical students and their involvement in global health activities and identify priorities of educational needs for developing GHE programs. @*Methods@#This study was cross-sectional and conducted through an online survey for medical students. The participants were students attending medical schools nationwide, and the final analysis target was 678. The survey developed questionnaires necessary for research purposes regarding global health-related experiences and perceptions, level of awareness of global health competencies (GHC), and needs assessments. The data were analyzed using the frequency analysis, chi-square test, independent t-test, Borich Needs Assessment Model, and the Locus for Focus Model. @*Results@#In total, 60.6% (411/678) agreed on the need for GHE, whereas 12.1% (82/678) agreed on the appropriateness of GHE in the current medical school curriculum, indicating a perception gap between the necessity and the status. At the current level of awareness of global health and GHC, we identified statistically significant differences according to gender, participation in global health activities, and GHE. In the analysis of the educational needs of GHC, all items of GHC had statistically significant differences between the importance level and the current level, and priorities were derived. The competency with the highest priority was domain A (Global Burden of Disease). @*Conclusion@#We expect the findings of this study to be used in Korean medical education as fundamental data to prepare a hereafter research foundation for GHE and discuss systematic GHE based on GHC.
ABSTRACT
Purpose@#This study aimed to reach a consensus among experts on the global health competencies for medical students in Korea. @*Methods@#A global health competency model was developed to identify domains and competencies for medical education, and a three-round modified Delphi method was used to reach consensus among 21 experts on the essential global health competencies. The degree of convergence, degree of consensus, and content validity ratio of the model were used to reach a consensus. @*Results@#A list of 52 competencies in 12 domains were identified according to a literature review. In the first-round Delphi survey, the global health competencies were refined to 30 competencies in eight domains. In the second round, the competencies were reduced to 24. In the final round, consensus was reached among the expert panel members, and the competencies were finalized. The global health competency domains for medical students include global burden of disease (three items), globalization of health and healthcare (five items), determinants of health (two items), healthcare in low-resource settings (two items), global health governance (three items), health as a human right (four items), cultural diversity and health (three items), and participation in global health activities (two items). @*Conclusion@#The group of experts in global health achieved a consensus that 24 global health competencies in eight domains were essential for undergraduate medical education in Korea. The domains and competencies identified herein can be used to develop an undergraduate medical education curriculum in global health.
ABSTRACT
This study investigated the current status and educational needs of global health education (GHE) at medical schools in Korea. Among the 40 medical schools nationwide, 32 schools that agreed to participate in the study collected data through a survey in 2022, and the results were examined by frequency analysis and content analysis. In total, 87.5% of medical schools included global health-related graduation outcomes. In the curriculum, global health lessons within courses were present at 71.9% of medical schools. Regarding extracurricular activities, 66.7% and 63.0% of medical schools offered overseas clerkships and overseas volunteer work, respectively. Although there were not many medical schools with a global health-related educational environment, 96.9% of schools agreed with the necessity of GHE in medical education. The prevailing opinion was that it was appropriate to continuously cover GHE as lessons within courses throughout all years of the program in medical education. The main opinions regarding the improvement of GHE related to curriculum development, personnel expansion, and awareness improvement at medical schools. These findings are expected to serve as a basis for identifying the current status of GHE at Korean medical schools and specifying future directions of GHE.
ABSTRACT
Background@#Several noninvasive tools are available for the assessment of nonalcoholic fatty liver disease (NAFLD) including clinical and blood biomarkers, transient elastography (TE), and magnetic resonance imaging (MRI) techniques, such as proton density fat fraction (MRI-PDFF) and magnetic resonance elastography (MRE). In the present study, we aimed to evaluate whether magnetic resonance (MR)-based examinations better discriminate the pathophysiologic features and fibrosis progression in NAFLD than other noninvasive methods. @*Methods@#A total of 133 subjects (31 healthy volunteers and 102 patients with NAFLD) were subjected to clinical and noninvasive NAFLD evaluation, with additional liver biopsy in some patients (n=54). @*Results@#MRI-PDFF correlated far better with hepatic fat measured by MR spectroscopy (r=0.978, P<0.001) than with the TE controlled attenuation parameter (CAP) (r=0.727, P<0.001). In addition, MRI-PDFF showed stronger correlations with various pathophysiologic parameters for cellular injury, glucose and lipid metabolism, and inflammation, than the TE-CAP. The MRI-PDFF and TE-CAP cutoff levels associated with abnormal elevation of serum alanine aminotransferase were 9.9% and 270 dB/m, respectively. The MRE liver stiffness measurement (LSM) showed stronger correlations with liver enzymes, platelets, complement component 3, several clinical fibrosis scores, and the enhanced liver fibrosis (ELF) score than the TE-LSM. In an analysis of only biopsied patients, MRE performed better in discriminating advanced fibrosis with a cutoff value of 3.9 kPa than the TE (cutoff 8.1 kPa) and ELF test (cutoff 9.2 kPa). @*Conclusion@#Our results suggest that MRI-based assessment of NAFLD is the best non-invasive tool that captures the histologic, pathophysiologic and metabolic features of the disease.
ABSTRACT
Background@#With an increase in the number of breast cancer survivors, greater importance is attached to health-related quality of life, particularly pain and symptom control. This study aimed to identify the factors that are associated with pain in cancer patients based on the patterns of prescribing opioid, non-opioid, and adjuvant analgesics. @*Methods@#This analysis included new patients who had developed breast cancer between 2003 and 2012. The degree of pain was analyzed based on the socio-demographic (age, income quintile, number of hospitalizations, and duration of disease), indicator (Body Mass Index; BMI, Charlson Comorbidity Index; CCI, Cumulative Analgesic Consumption Score; CACS), operation (mastectomy, lymph node dissection), and therapy (chemotherapy, radiation therapy), as well as complication-related variable (lymphedema). @*Results@#As for the patterns of prescribing analgesics by stages, non-opioid and opioid analgesics constituted 30.7 and 69.3%, respectively. The mean value and variance of CACS were 5.596 and 12.567, respectively. The factors that significantly affected the degree of pain were age (≥50; IRR: 1.848, 95% CI 1.564-2.184, p=0.000), income quintile (IRR: 0.964, 95% CI 0.938-0.991, p=0.008), BMI (≥ 25; IRR: 1.479, 95% CI 1.222-1.795, p= 0.000), CCI (≥ 4; IRR: 1.649, 95% CI 1.344-2.036, p=0.000), and lymphedema (yes; IRR: 1.267, 95% CI 1.006-1.610, p=0.047). @*Conclusions@#It is necessary to develop systematic and comprehensive pain control measures to improve the quality of life for breast cancer survivors, especially for those who are 50 years or older, lie in the lower-income quintile, have BMI of ≥25 and CCI score ≥ 4, or have lymphedema.

ABSTRACT
Background@#The purpose of this study is to conduct a teamwork program for pre-medical students using a table-top simulation game called Friday Night at the ER®, and to investigate the effect. @*Methods@#This is a one group pretest-posttest design study 34 students. The tools were understanding of interpersonal relationships (11 questions), problem-solving initiative (8 questions), and system thinking (20 questions) were used. Satisfaction with the program was investigated, and a self-reflection essay was written. For the analysis, paired t-test, frequency analysis, and content analysis were used. @*Results@#After participating in the program, interpersonal understanding, proactivity in problem-solving, and systems thinking all significantly improved (p<.001), and the effect size of the program was also above medium (Cohen’s d= 0.580∼1.019). As a result of analyzing the contents of the self-reflection journal, it was classified into 7 themes and 3 categories; Teamwork competency, systems thinking skills, interpersonal skills. Students were generally satisfied with the program. @*Conclusion@#The simulation game-based teamwork program was effective in improving students’ teamwork. These results can be used as basic data for medical schools designing such programs.

ABSTRACT
Background@#Sedentary behavior (SB) has emerged as a new risk factor for cardiovascular accidents. We investigated whether physical activity levels or SB were related to percent body fat (%BF) in type 2 diabetes mellitus (T2DM). @*Methods@#In this cross sectional study, we measured the duration of SB, light physical activity (LPA), moderate to vigorous physical activity (MVPA), total energy expenditure, and step counts using a wireless activity tracker (Fitbit HR; FB) for 7 days in freeliving conditions, along with %BF using a bio impedance analyzer (Inbody; Biospace) in 120 smartphone users with T2DM. Subjects were divided into exercise (Exe, n=68) and non-exercise (nonExe, n=52) groups based on self-reports of whether the recommended exercises (30 min/day, 3 days/week for 3 months) were performed. SBt, LPAt, MVPAt were transformed from SB, LPA, MVPA for normally distributed variables. @*Results@#Participants were: female, 59.2%; age, 59.3±8.4 years; body mass index, 25.5±3.4 kg/m2; glycosylated hemoglobin (HbA1c), 7.6%±1.2%; %BF, 30.4%±7.1%. They performed SB for 15.7±3.7 hr/day, LPA for 4.4±1.7 hr/day, and MVPA for 0.9±0.8 hr/day. The %BF was related to SBt and LPAt, but not to MVPA after adjustments for age, gender, and HbA1c. VPA was significantly higher in the Exe group than in the nonExe group, but SB, LPA, and moderate physical activity were not different. Predicted %BF was 89.494 to 0.105 (age), –13.047 (gender), –0.507 (HbA1c), –7.655 (LPAt) (F[4, 64]=62.929, P<0.001), with an R2 of 0.785 in multiple linear regression analysis. @*Conclusion@#Reduced body fat in elderly diabetic patients might be associated with reduced inactivity and increased LPA.
ABSTRACT
BackgroundThis study was a multicenter, parallel-group, double-blind, double-dummy, randomized,noninferiority trial to evaluate the efficacy and safety of γ-linolenic acid(GLA) relative to α-lipoic acid (ALA) over a 12-week treatment period in type 2diabetes mellitus (T2DM) patients with painful diabetic peripheral neuropathy (DPN).MethodsThis study included 100 T2DM patients between 20 and 75 years of age who had painfulDPN and received either GLA (320 mg/day) and placebo or ALA (600 mg/day) and placebo for12 weeks. The primary outcome measures were mean changes in pain intensities as measuredby the visual analogue scale (VAS) and the total symptom scores (TSS).ResultsOf the 100 subjects who initially participated in the study, 73 completed the 12-weektreatment period. Per-protocol analyses revealed significant decreases in the mean VASand TSS scores compared to baseline in both groups, but there were no significantdifferences between the groups. The treatment difference for the VAS (95% confidenceinterval [CI]) between the two groups was −0.65 (−1.526 to 0.213) and theupper bound of the 95% CI did not exceed the predefined noninferiority margin(δ1=0.51). For the TSS, the treatment difference was −0.05(−1.211 to 1.101) but the upper bound of the 95% CI crossed the noninferioritymargin (δ2=0.054). There were no serious adverse events associatedwith the treatments.ConclusionGLA treatment in patients with painful DPN was noninferior to ALA in terms of reducingpain intensity measured by the VAS over 12 weeks.
ABSTRACT
OBJECTIVE: The aim of this study was to investigate the effects of omega-3 fatty acids added to statin monotherapy in Korean patients with type 2 diabetes who have persistent hypertriglyceridemia despite statin therapy. METHODS: This study was a randomized controlled trial conducted in 4 clinical sites between February 2009 and February 2011. The inclusion criteria were patients with type 2 diabetes who had received ≥6 weeks of statin therapy and had fasting triglyceride (TG) levels ≥1.7mmol/L and low-density lipoprotein (LDL) cholesterol levels <2.6 mmol/L. The study regimen consisted of 16 weeks of randomized treatment with omega-3 fatty acids (4 g/day) plus a statin (n=26) or statin only (n=30). The primary endpoint was the change from baseline to final visit in mean TG level. RESULTS: A total of 56 participants were analyzed. At week 16, the change in the TG level in the combination therapy group differed significantly from the change in the statin monotherapy group (−34.8% vs. −15.2%, p=0.0176). Treatment with omega-3 fatty acids plus a statin was also associated with a significant decrease in non-high-density lipoprotein cholesterol compared with baseline, but the difference was not significant compared with the statin monotherapy group (−8.0% vs. −2.5%, p=0.165). The changes in LDL cholesterol and HbA1c levels did not differ significantly between groups. The study medications were well tolerated, and adverse events were comparable between two groups. CONCLUSION: Adding omega-3 fatty acids to statin treatment reduced TG levels more effectively than statin monotherapy without undesirable effects in Korean type 2 diabetic patients who had hypertriglyceridemia despite well-controlled LDL cholesterol on stable statin therapy.

PURPOSE: There has been limited research on physicians’ perceptions of the specialty characteristics that are needed to sustain a successful career in medical specialties in Korea. Medical Specialty Preference Inventory in the United States or SCI59 (specialty choice inventory) in the United Kingdom are implemented to help medical students plan their careers. The purpose of this study was to explore the characteristics of the major specialties in Korea. METHODS: Twelve physicians from different specialties participated in an exploratory study consisting of qualitative interviews about the personal ability and emotional characteristics and job attributes of each specialty. The collected data were analysed with content analysis methods. RESULTS: Twelve codes were extracted for ability & skill attributes, 23 codes for emotion & attitude attributes, and 12 codes for job attributes. Each specialty shows a different profile in terms of its characteristic attributes. CONCLUSION: The findings have implications for the design of career planning programs for medical students.

BACKGROUND: The aim of this study was to assess the psychological well-being and treatment satisfaction in patients with type 2 diabetes mellitus in a general hospital in Korea. METHODS: This study included 440 type 2 diabetes patients above 20 years of age. Well-Being Questionnaire-12 (WBQ-12) and Diabetes Treatment Satisfaction Questionnaire were used to survey well-being and treatment satisfaction, respectively. WBQ-12 consists of 4 categories: negative well-being (NWB), energy (ENE), positive well-being (PWB), and general well-being (GWB). RESULTS: There were significant associations between NWB scores and women, low education, low-income, and number of hospital admissions. Significant associations were also identified between ENE scores and men, higher education, insulin nonusers, high-income, compliance with recommended exercise, number of medications, satisfaction with treatment time, and poor glycemic control. PWB scores were significantly associated with high-income, satisfaction with waiting and treatment times, compliance with recommended diet and exercise, and number of medications. GWB scores were significantly associated with men, higher education, high-income, satisfaction with waiting and treatment times, compliance with recommended exercise, and number of medications. Treatment satisfaction was significantly associated with age, satisfaction with waiting and treatment times, compliance with recommended diet and exercise, and duration of diabetes. CONCLUSION: Diabetes care requires psychosocial support in addition to medical care. Unlike Western studies, our study found that satisfaction with waiting and treatment times had a strong correlation with well-being and treatment satisfaction in diabetes patients.

BACKGROUND: Multiple endocrine neoplasia type 1 (MEN1) is a rare inherited disorder characterized by the simultaneous occurrence of endocrine tumors in target tissues (mainly the pituitary, endocrine pancreas, and parathyroid glands). MEN1 is caused by mutations in the MEN1 gene, which functions as a tumor suppressor and consists of one untranslated exon and nine exons encoding the menin protein. This condition is usually suspected when we encounter patients diagnosed with tumors in multiple endocrine organs, as mentioned above. METHODS: A 65-year-old woman who underwent surgery for a pancreatic tumor (serous cystadenoma) 5 years previously was referred to our hospital due to neurologic symptoms of diplopia and left ptosis. Brain magnetic resonance imaging revealed a 3.4-cm lesion originating from the cavernous sinus wall and extending into the sellar region. It was thought to be a nonfunctioning tumor from the results of the combined pituitary function test. Incidentally, we found that she also had a pancreatic tumor, indicating the necessity of genetic analysis for MEN1. RESULTS: Genomic analysis using peripheral leukocytes revealed a heterozygous c.1621G>A mutation in the MEN1 gene that was previously reported to be either a pathogenic mutation or a simple polymorphism. We pursued a stereotactic approach to the pituitary lesion, and microscopic findings of the tumor revealed it to be an intrasellar cavernous hemangioma, a rare finding in the sellar region and even rarer in relation to oculomotor palsy. The patient recovered well from surgery, but refused further evaluation for the pancreatic lesion. CONCLUSION: There is great emphasis placed on genetic testing in the diagnosis of MEN1, but herein we report a case where it did not assist in diagnosis, hence, further discussion on the role of genetic testing in this disease is needed. Also, in cases of pituitary tumor with cranial nerve palsy, despite its low prevalence, intrasellar cavernous hemangioma could be suspected.

Diabetes mellitus is a major risk factor for urinary tract infection (UTI); emphysematous pyelonephritis (EP), a complication of UTIs, often occurs in patients with underlying, poorly controlled diabetes mellitus. We report the case of an 87-year-old woman with EP in type 2 diabetes mellitus who developed pneumatosis cystoides intestinalis (PCI) with portal venous gas. PCI is a radiographic finding, which is found in a linear or cystic form of gas in the submucosa or subserosa of the bowel wall. PCI has two common presentations. Primary PCI is a benign idiopathic condition. Secondary PCI is associated with a wide variety of gastrointestinal and non-gastrointestinal diseases. PCI with portal venous gas in particular is associated with ischemic gastrointestinal disease. Initial pre-enhanced abdominopelvic computed tomography showed EP in the right kidney without PCI. Newly occurring PCI and hepatic portal venous gas were found in the right ascending colon after EP improved. This is a rare case of PCI accompanied by emphysematous pyelonephritis in type 2 diabetes mellitus. The patient's general condition improved with intravenous antibiotics and fluid therapy without a surgical approach. However, she was discharged without further treatment because the family refused any further evaluations and treatments.

PURPOSE: Medical students experience various stresses that arise in a special environment. However, there is no specific stress scale for medical students with regard to their environment in Korea. Therefore, in this study, we developed and confirmed the validity of a stress scale for medical students in Korea. METHODS: A draft version of the scale was developed on the basis of open-ended questionnaires from 97 medical students. The validity of the content of this scale was evaluated by three medical educationists. The scale was administered to 435 third and fourth grade medical students as the main survey. For our data, we performed an exploratory factor analysis and confirmatory factor analysis. We used Cronbach alpha index to determine internal consistency. RESULTS: Six factors with 40 items were extracted through the exploratory factor analysis: academic stress (9 items); clerkship stress (11 items); interpersonal stress (7 items); career stress (8 items); health-related stress (3 items); and financial stress (2 items). These factors showed a statistically significant correlation. The confirmatory factor analysis demonstrated a favorable RMSEA (0.053) and reasonable fit (CFI=0.847, TLI=0.833). Cronbach alpha values of the six factors ranged from 0.63 to 0.85. CONCLUSION: The medical student stress scale had a good model fit. It is a valid and reliable instrument in identifying stress in medical students and can be used in future studies. Also, the scale is expected to provide individual stress profiles for students to help them manage stress more effectively.

There are many studies on the prevalence, clinical characteristics, and economic burden of diabetes across the past four decades in Korea. Nonetheless, there is a dearth of nationwide study regarding diabetes encompassing all age group. Eight years ago, the Committee on the Epidemiology of Diabetes Mellitus of Korean Diabetes Association collaborated with Health Insurance Review & Assessment Service to evaluate the status of diabetes care and characteristics in diabetic patients in Korea. In 2007, the collaborative task force team published a comprehensive survey titled "Diabetes in Korea 2007." In this review, we reappraise the diabetic epidemics from the joint report and suggest further studies that are needed to be investigated in the future.

The aim of the study was to assess the association between usual dietary nutrient intake and obesity in Korean type 2 diabetic patients. We examined 2,832 type 2 diabetic patients from the Korean National Diabetes Program cohort who completed dietary assessment and clinical evaluation in this cross-sectional study. In men, higher dietary fiber intake was associated with a lower odds of being obese (Ptrend = 0.003) and in women, higher protein intake was associated with a lower odds of being obese (Ptrend = 0.03) after adjustment for age, diabetes duration, HbA1c, alcohol drinking, income, education level, and calorie intake. In men, higher fiber intake was associated with lower odds of obesity after further adjustment for diastolic blood pressure, physical activity, and possible confounding nutritional intake and medication. The multivariable adjusted odds ratio for the highest quintile of fiber intake was 0.37 (Ptrend < 0.001). In women, protein intake was not associated with obesity after further adjustment. In conclusion, higher intake of dietary fiber is associated with lower odds of being obese in type 2 diabetic men, suggesting a role for dietary fiber in the management and prevention of obesity in type 2 diabetes (ClinicalTrials.gov: NCT 01212198).

Neurofibromatosis type 1 (NF1) is one of the most common autosomal dominant inherited disorders affecting the nervous system. NF1 is associated with mutations in the NF1 gene, which is located on chromosome sub-band 17q11.2 and contains 57 exons spanning approximately 300 kb of genomic DNA. NF1 is caused by a loss of function mutation of the NF1 gene, a tumor suppressor gene, which encodes for neurofibromin, a GTPase-activating protein (GAP) involved in the negative regulation of Ras activity. The GAP-related domain, which is encoded for by exons 20-27a, is one of the most important functional domains in neurofibromin. The cysteine-serine-rich domain has been recognized as an important functional domain in NF1-related pheochromocytomas. As the result of many genetic analyses of NF1-related pheochromocytomas, pheochromocytoma has generally been recognized as a true component of NF1. We recently experienced two families with NF1 accompanied by pheochromocytoma. The proband of family 1 is a 31-year-old female diagnosed with NF1 and pheochromocytoma. Gene analysis of the proband and her sister showed that the mutation of the NF1 gene (c.7907+1G>A) led to the skipping of exon 53 during NF1 mRNA splicing. The proband of family 2 is a 48-year-old male who was diagnosed with the same condition. Gene analysis demonstrated the mutation of the NF1 gene (c.5206-8C>G) with missplicing of exon 37. These novel germline mutations did not fall into the GAP-related nor the cysteine-serine-rich domains, but into the C-terminal area of the NF1 gene. This suggests that the correlation between the genotype and phenotype of NF1-related pheochromocytoma is somewhat difficult to characterize. Further studies will be necessary to confirm the function of the C-terminal area of the NF1 gene and its contribution to the development of NF1 and pheochromocytoma.
