Only few studies have shown the efficacy and safety of glucose-control strategies using the quadruple drug combination. Therefore, the aim of the present study was to investigate the usefulness of the quadruple combination therapy with oral hypoglycemic agents (OHAs) in patients with uncontrolled type 2 diabetes mellitus (T2DM).

Background: Only few studies have shown the efficacy and safety of glucose-control strategies using the quadruple drug combination. Therefore, the aim of the present study was to investigate the usefulness of the quadruple combination therapy with oral hypoglycemic agents (OHAs) in patients with uncontrolled type 2 diabetes mellitus (T2DM). Methods: From March 2014 to December 2018, data of patients with T2DM, who were treated with quadruple hypoglycemic medications for over 12 months in 11 hospitals in South Korea, were reviewed retrospectively. We compared glycosylated hemoglobin (HbA1c) levels before and 12 months after quadruple treatment with OHAs. The safety, maintenance rate, and therapeutic patterns after failure of the quadruple therapy were also evaluated. Results: In total, 357 patients were enrolled for quadruple OHA therapy, and the baseline HbA1c level was 9.0%±1.3% (74.9± 14.1 mmol/mol). After 12 months, 270 patients (75.6%) adhered to the quadruple therapy and HbA1c was significantly reduced from 8.9%±1.2% to 7.8%±1.3% (mean change, –1.1%±1.2%; P<0.001). The number of patients with HbA1c <7% increased significantly from 5 to 68 (P<0.005). In addition, lipid profiles and liver enzyme levels were also improved whereas no changes in body weight. There was no significant safety issue in patients treated with quadruple OHA therapy. Conclusion This study shows the therapeutic efficacy of the quadruple OHA regimen T2DM and demonstrates that it can be an option for the management of T2DM patients who cannot use insulin or reject injectable therapy.

Diabetes mellitus (DM) is a group of metabolic disorders, that have become a major cause of death worldwide. This study aimed to determine the usefulness of diabetes-related laboratory tests for diagnosis of postmortem DM. From March to August 2018, among the autopsy cases investigated by the National Forensic Service, heart blood and vitreous humor samples from 253 cases that had not been decomposed were collected, and the data from 208 cases except 45 cases that were incapable of testing were analyzed for statistical significance and compared with the causes of death on autopsy reports. The levels of C-peptide, insulin, acetoacetate, β-hydroxybutyrate (β-HA), total ketone, and HbA1c were measured in the heart blood, and the levels of glucose, blood urea nitrogen, creatinine, and potassium were measured in the vitreous humor. The levels of glucose in the vitreous humor and HbA1c, β-HA, and total ketone in the heart blood were significantly correlated. C-peptide and insulin levels were lower than normal levels in most cases (C-peptide 92.3%, P=0.480, insulin 97.6%, P=0.589), and were not useful measures indicating diabetic complications. In the group with DM history, the average levels of HbA1c from the heart blood and glucose from the vitreous humor were higher than in those with no or unknown history of DM, indicating their usefulness as diagnostic tools. The results of this study suggest a postmortem DM diagnosis model.Therefore, postmortem DM-related tests can help diagnose the cause of death in forensic medicine.

INTRODUCTIONFrequent admitters to hospitals are high-cost patients who strain finite healthcare resources. However, the exact risk factors for frequent admissions, which can be used to guide risk stratification and design effective interventions locally, remain unknown. Our study aimed to identify the clinical and sociodemographic risk factors associated with frequent hospital admissions in Singapore.

METHODSAn observational study was conducted using retrospective 2014 data from the administrative database at Singapore General Hospital, Singapore. Variables were identified a priori and included patient demographics, comorbidities, prior healthcare utilisation, and clinical and laboratory variables during the index admission. Multivariate logistic regression analysis was used to identify independent risk factors for frequent admissions.

RESULTSA total of 16,306 unique patients were analysed and 1,640 (10.1%) patients were classified as frequent admitters. On multivariate logistic regression, 16 variables were independently associated with frequent hospital admissions, including age, cerebrovascular disease, history of malignancy, haemoglobin, serum creatinine, serum albumin, and number of specialist outpatient clinic visits, emergency department visits, admissions preceding index admission and medications dispensed at discharge. Patients staying in public rental housing had a 30% higher risk of being a frequent admitter after adjusting for demographics and clinical conditions.

CONCLUSIONOur study, the first in our knowledge to examine the clinical risk factors for frequent admissions in Singapore, validated the use of public rental housing as a sensitive indicator of area-level socioeconomic status in Singapore. These risk factors can be used to identify high-risk patients in the hospital so that they can receive interventions that reduce readmission risk.

PURPOSE: Nurses' knowledge regarding advance directives may affect their administration of and confidence towards end of life care. This study aimed to describe the relationships of knowledge, confidence, and learning needs with advance directives among hospital nurses.METHOD: This cross-sectional study was performed at a tertiary university hospital in Seoul between September 25 and October 14, 2017. Convenience sampling was used to recruit nurses who provided bedside care and had at least 1 year of clinical experience. We used a validated self-report questionnaire.RESULTS: The mean score of knowledge, confidence and learning needs were 5.00±1.73, 29.81±7.52, and 64.54±8.48 respectively. Hospital nurses' knowledge, confidence and learning needs were significantly different according to age, job position, educational level and perceived advance directives. Knowledge regarding advance directives was significantly associated with confidence (r = .27, p < .001) and learning needs (r = .16, p = .005).CONCLUSION: Knowledge regarding advance directives was relatively low compared to the findings of previous studies. Therefore, nurses should be knowledgeable and encouraged to initiate advance directives. It is necessary to develop a standardized educational program regarding advance directives based on Korean cultures.

The differential diagnosis of systemic lupus erythematosus (SLE) and autoimmune hepatitis (AIH) is difficult due to the resemblance of these two disorders. However, the accurate diagnosis is important for prognosis and treatment that are different from each other. We report a case of AIH-SLE overlap syndrome which tapering of prednisone and azathioprine therapy deteriorated the condition of a patient due to flare up of SLE. The patient was a 28-year-old woman diagnosed as AIH. After administrations of prednisone and azathioprine, her condition was improved. During dose reduction, she was admitted to our hospital as fever and dyspnea. She diagnosed as lupus nephritis. After high dose treatment with corticosteroids and azathioprine, she recovered. Once the diagnosis of autoimmune disease such as SLE or AIH has been made, clinicians should also be fully aware of concomitant other autoimmune disease.

BACKGROUND: Thyroid function depends on ethnic and environmental factors. North Korean refugees have the same genetic background as South Koreans, but they have been exposed to different environments. This study examines the prevalence and pattern of thyroid disorders in North Korean women living in South Korea, focusing on subclinical hypothyroidism (SCH). METHODS: The intended sample was a total of 327 North Korean women residing in Seoul. Health questionnaires and medical examinations, including serum thyrotropin (thyroid stimulating hormone, TSH), free thyroxine, and thyroid autoantibodies, were conducted. RESULTS: The prevalence of SCH was 9.4%. In logistic regression analysis, smoking, menopause, length of stay in South Korea, body mass index, history of thyroid disease, and metabolic syndrome were not associated with the risk of SCH. Whereas, the positivity of autoantibodies were associated with a high risk for SCH (odds ratio [OR], 4.840; 95% confidence interval [CI], 1.80-13.017; P = 0.002), and age was associated with a low risk for SCH (OR, 0.94; 95% CI, 0.888-0.994; P = 0.031). The serum TSH levels also decreased with increasing age, and in particular, there was significant difference between 30-39 years, and over 60 years (2.33 +/- 1.51 microIU/mL vs. 1.54 +/- 0.73 microIU/mL, P = 0.028). CONCLUSION: In North Korean women, the positivity of autoantibodies was associated with a high risk for SCH. But interestingly, a younger age was associated with a high risk for SCH. Considering that they suffered from severe famine at the period of growth, and this led to malnutrition, their thyroid dysfunction might be associated with the peculiar environment that they experienced.

PURPOSE: This study was done to analyze the job of clinical research coordinators (CRCs). METHODS: Through the "developing a curriculum (DACUM)" workshop, the definition of CRCs' role was described and CRCs' duties and tasks were identified. Finally, the developed duties and tasks were validated for importance, difficulty, and frequency. RESULTS: A CRC is defined as the one who coordinates and performs tasks related to clinical research/trials among investigators, participants, and sponsors according to the Good Clinical Practice at institutions conducting clinical trials. Twelve duties and 78 tasks were identified on the DACUM chart which represented the importance, difficulty, and frequency of tasks represented as A, B, and C respectively. Based on determinant coefficient (DC) of the task, the highest ranked task was confirming the eligibility of participants for research (DC=8.03) and the lowest was inventory management for clinical study materials (3.95). CONCLUSION: In this study, the job of a CRC was analyzed through the DACUM process and it was found that CRCs were doing various duties and tasks. Based on these results, it is suggested that it is necessary to develop CRC education programs considering the career ladder of CRCs.

PURPOSE: This study was done to evaluate the formal education program provided by the Korean government for care workers for frail elderly people. METHODS: This study was a cross-sectional survey in which 438 certified care workers who had completed the education program participated. Data were collected from June to October 2009, using a self-report questionnaire consisting of satisfaction with, and understanding of the education program. RESULTS: The participants had a mean age of 46.7 yr, 87.9% were female and 58.2% were high school graduates. For the theory part of the education, the highest score for understanding was for 'supporting household & activities of daily living' while the lowest score for understanding was for 'care for death and dying'. For the practical education, the highest score for understanding was for 'talking with the client' and the lowest score was for 'first aid & basic life support'. There was a significant difference in satisfaction and understanding of the theoretical and practical parts according to educational level. CONCLUSION: Continuing education programs are needed for care workers for elders, both in the theoretical and practical areas. Also the content of programs should address the weak points of this formal education program.
