ABSTRACT

Purpose@#Since diabetes and hypertension frequently occur together, it is thought that these conditions may have a common pathogenesis. This study was designed to evaluate the anti-diabetic function of the anti-hypertensive drug fimasartan on C2C12 mouse skeletal muscle and HepG2 human liver cells in a high glucose state. @*Materials and Methods@#The anti-diabetic effects and mechanism of fimasartan were identified using Western blot, glucose uptake tests, oxygen consumption rate (OCR) analysis, adenosine 5'-triphosphate (ATP) enzyme-linked immunosorbent assay (ELISA), and immunofluorescence staining for diabetic biomarkers in C2C12 cells. Protein biomarkers for glycogenolysis and glycogenesis were evaluated by Western blotting and ELISA in HepG2 cells. @*Results@#The protein levels of phosphorylated 5' adenosine monophosphate-activated protein kinase (p-AMPK), p-AKT, insulin receptor substrate-1 (IRS-1), and glucose transporter type 4 (Glut4) were elevated in C2C12 cells treated with fimasartan. These increases were reversed by peroxisome proliferator-activated receptor delta (PPARδ) antagonist. ATP, OCR, and glucose uptake were increased in cells treated with 200 μM fimasartan. Protein levels of glycogen phosphorylase, glucose synthase, phosphorylated glycogen synthase, and glycogen synthase kinase-3 (GSK-3) were decreased in HepG2 cells treated with fimasartan. However, these effects were reversed following the addition of the PPARδ antagonist GSK0660. @*Conclusion@#In conclusion, fimasartan ameliorates deteriorations in glucose metabolism as a result of a high glucose state by regulating PPARδ in skeletal muscle and liver cells.

ABSTRACT

Background@#Obesity, the prevalence of which is increasing due to the lack of exercise and increased consumption of Westernized diets, induces various complications, including ophthalmic diseases. For example, obesity is involved in the onset of cataracts. @*Methods@#To clarify the effects and mechanisms of midodrine, an α1-adrenergic receptor agonist, in cataracts induced by obesity, we conducted various analytic experiments in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a rat model of obesity. @*Results@#Midodrine prevented cataract occurrence and improved lens clearance in OLETF rats. In the lenses of OLETF rats treated with midodrine, we observed lower levels of aldose reductase, tumor necrosis factor-α, and sorbitol, but higher levels of hexokinase, 5’-adenosine monophosphate-activated protein kinase-alpha, adenosine 5´-triphosphate, peroxisome proliferator-activated receptordelta, peroxisome proliferator-activated receptor gamma coactivator 1-alpha, superoxide dismutase, and catalase. @*Conclusion@#The ameliorating effects of midodrine on cataracts in the OLETF obesity rat model are exerted via the following three mechanisms: direct inhibition of the biosynthesis of sorbitol, which causes cataracts; reduction of reactive oxygen species and inflammation; and (3) stimulation of normal aerobic glycolysis.

ABSTRACT

Background@#The prevalence of non-alcoholic fatty liver disease (NAFLD) has rapidly increased worldwide. The aim of this study was to investigate whether there is an independent relationship between regional fat distribution, especially leg fat mass, and the presence of NAFLD using nationally representative data in Korea. @*Methods@#This cross-sectional study analyzed data from 14,502 participants in the Korea National Health and Nutrition Examination Survey 2008 to 2011. Total fat mass, leg fat mass, and appendicular skeletal muscle mass were measured by dual-energy X-ray absorptiometry. Validated NAFLD prediction models and scoring systems for hepatic fibrosis were used. @*Results@#The leg fat to total fat (LF/TF) ratio showed a negative relationship with many factors, including body mass index, waist circumference, blood pressure, fasting blood glucose, and liver enzyme levels. When the LF/TF ratio and indices of hepatic steatosis were stratified by quartiles, the LF/TF ratio showed a negative correlation with the scoring systems that were used. The LF/TF ratio showed better accuracy in predicting NAFLD than total fat mass or leg fat mass alone. After adjusting for various traditional and lifestyle factors, a low LF/TF ratio remained a risk factor for NAFLD. Among NAFLD subjects, the LF/TF ratio showed a negative relationship with hepatic fibrosis. @*Conclusion@#A lower LF/TF ratio was markedly associated with a higher risk of hepatic steatosis and advanced hepatic fibrosis using various predictive models in a Korean population. Therefore, the LF/TF ratio could be a useful anthropometric parameter to predict NAFLD or advanced hepatic fibrosis.

ABSTRACT

Recently three-dimensional (3D) printed complete dentures are becoming more widely recognized as one of the treatment options for the edentulous patients. Korean National Healthcare, however, has not yet approved the application of the 3D printed dentures, and in the cases where the dentures should be refabricated, the conventional fabrication process needs to be entirely repeated.However, during the conventional process, the digital scan data of some key steps could be easily obtained. In this clinical case, using these data, a new pair of 3D printed dentures that improved the limitations of the first conventional dentures were successfully fabricated.

ABSTRACT

Objective@#The aim of this study was to analyze the available knowledge about the potential association between dyslipidemia and the severity of coronavirus disease 2019 (COVID-19) as reported in previous published systematic reviews. @*Methods@#In this umbrella review (an overview of systematic reviews), we investigated the association between dyslipidemia and COVID-19 severity. A systematic search was performed of 4 main electronic databases (MEDLINE, Embase, Scopus, and the Cochrane Library databases) from inception until August 2020. We evaluated the methodological quality of the included studies using the A MeaSurement Tool to Assess systematic Reviews (AMSTAR) 2 tool and used the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to assess the quality of evidence for the outcome. In addition, we evaluated the strengths and limitations of the evidence and the methodological quality of the available studies. @*Results@#Out of 35 articles identified, 2 systematic reviews were included in the umbrella review. A total of 7,951 COVID-19-positive patients were included. According to the AMSTAR 2 criteria and GRADE system, the quality of the included studies was not high. A history of dyslipidemia is likely to be associated with the severity of COVID-19 infection, but the contrary is the case for cholesterol levels at hospitalization. @*Conclusions@#Although existing research on dyslipidemia and COVID-19 is limited, our findings suggest that dyslipidemia may play a role in the severity of COVID-19 infection. More adequately powered studies are needed.

ABSTRACT

BACKGROUND: Hyperglycemic crisis is a metabolic emergency associated with diabetes mellitus. However, accurate epidemiologic information on cases of hyperglycemic crisis in Korea remains scarce. We evaluated trends in hyperglycemic crisis hospitalizations and in- and out-of-hospital mortality in Korea. We also predicted future trends. METHODS: We extracted claims data with hyperglycemic crisis as the principal diagnosis from the National Health Insurance Service database in Korea from January 2004 to December 2013. We investigated the numbers of claims with hyperglycemic crisis and identified trends in hyperglycemic crisis based on those claims data. We predicted future trends by statistical estimation. RESULTS: The total annual number of claims of hyperglycemic crisis increased from 2,674 in 2004 to 5,540 in 2013. Statistical analysis revealed an increasing trend in hyperglycemic crisis hospitalizations (P for trend <0.01). In contrast, the hospitalization rate per 1,000 diabetes cases showed a decreasing trend (P for trend <0.01) during this period. The mortality rate per 1,000 diabetes cases also showed a decreasing trend (P for trend <0.0001). However, no distinct linear trend in the case-related fatality rate at <60 days over the last decade was observed. The predicted number of annual claims of hyperglycemic crisis will increase by 2030. CONCLUSION: The number of hyperglycemic crisis hospitalizations in Korea increased in the last decade, although the hospitalization rate per 1,000 diabetes cases and mortality rate decreased. Also, the predicted number of annual claims will increase in the future. Thus, it is necessary to establish long-term healthcare policies to prevent hyperglycemic crisis.

ABSTRACT

The apoptotic effects of shikonin (5,8-dihydroxy-2-[(1R)-1-hydroxy-4-methylpent-3-enyl]naphthalene-1,4-dione) on the human colon cancer cell line SNU-407 were investigated in this study. Shikonin showed dose-dependent cytotoxic activity against SNU-407 cells, with an estimated IC50 value of 3 µM after 48 h of treatment. Shikonin induced apoptosis, as evidenced by apoptotic body formation, sub-G1 phase cells, and DNA fragmentation. Shikonin induced apoptotic cell death by activating mitogen-activated protein kinase family members, and the apoptotic process was mediated by the activation of endoplasmic reticulum (ER) stress, leading to activation of the PERK/elF2α/CHOP apoptotic pathway, and mitochondrial Ca2+ accumulation. Shikonin increased mitochondrial membrane depolarization and altered the levels of apoptosis-related proteins, with a decrease in B cell lymphoma (Bcl)-2 and an increase in Bcl-2-associated X protein, and subsequently, increased expression of cleaved forms of caspase-9 and -3. Taken together, we suggest that these mechanisms, including MAPK signaling and the ER-and mitochondria-mediated pathways, may underlie shikonin-induced apoptosis related to its anticancer effect.

ABSTRACT

BACKGROUND: Sitagliptin is a novel antidiabetic agent with a low risk for hypoglycemia. We investigated the efficacy and safety of sitagliptin when patients switched from a sulfonylurea to sitagliptin and identified good candidates for the switch. METHODS: Sixty-one patients with type 2 diabetes switched from glimepiride with metformin to sitagliptin with metformin due to clinical hypoglycemia. Serum glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), and 2-hour postprandial plasma glucose (2h-PPG) before and 12 and 24 weeks after the drug switch were checked. RESULTS: HbA1c and FPG levels did not change 12 or 24 weeks after the switch; however, the 2h-PPG level decreased from 218.0+/-67.5 mg/dL at baseline to 197.1+/-69.9 mg/dL at 12 weeks and 192.3+/-67.4 mg/dL at 24 weeks after switching drugs (P=0.045, P=0.018, respectively). All but one patient no longer experienced hypoglycemia after discontinuing glimepiride. In a multivariate logistic regression analysis, a high homeostasis model assessment of insulin resistance and low baseline HbA1c level were independent predictors of an HbA1c < or =7% after switching to sitagliptin. CONCLUSION: Glycemic control was not aggravated in patients 24 weeks after the drug switch, and symptomatic hypoglycemia decreased significantly. Patients with dominant insulin resistance may be good candidates for switching from a sulfonylurea to sitagliptin to reduce hypoglycemia.

ABSTRACT

BACKGROUND: Type 1 diabetes is associated with more severe glycemic variability and more frequent hypoglycemia than type 2 diabetes. Glycemic variability is associated with poor glycemic control and diabetic complications. In this study, we demonstrate the clinical usefulness of serum 1,5-anhydroglucitol (1,5-AG) for assessing changes in glycemic excursion in type 1 diabetes. METHODS: Seventeen patients with type 1 diabetes were enrolled in this study. A continuous glucose monitoring system (CGMS) was applied twice at a 2-week interval to evaluate changes in glycemic variability. The changes in serum glycemic assays, including 1,5-AG, glycated albumin and hemoglobin A1c (HbA1c), were also evaluated. RESULTS: Most subjects showed severe glycemic excursions, including hypoglycemia and hyperglycemia. The change in 1,5-AG level was significantly correlated with changes in the glycemic excursion indices of the standard deviation (SD), mean amplitude of glucose excursion (MAGE), lability index, mean postmeal maximum glucose, and area under the curve for glucose above 180 mg/dL (r=-0.576, -0.613, -0.600, -0.630, and -0.500, respectively; all P<0.05). Changes in glycated albumin were correlated with changes in SD and MAGE (r=0.495 and 0.517, respectively; all P<0.05). However, changes in HbA1c were not correlated with any changes in the CGMS variables. CONCLUSION: 1,5-AG may be a useful marker for the assessment of short-term changes in glycemic variability. Furthermore, 1,5-AG may have clinical implications for the evaluation and treatment of glycemic excursions in type 1 diabetes.

ABSTRACT

Critically ill patients often experience hyperglycemia, which may be associated with increased morbidity and mortality. In 2001, van den Berghe et al. suggested significant benefit of normalization of blood glucose level in critically ill patients using intensive intravenous insulin therapy. Subsequent multicenter randomized studies, however, demonstrated adverse effects of tight glucose control. Therefore, while the need for glucose control in critically ill patients is generally accepted, the treatment thresholds for initiation of insulin therapy or target glucose values are still undetermined. Furthermore, occurrence of a hypoglycemic event during intensive insulin therapy is known to be an independent predictor of clinical outcome, and glycemic variability is an important variable of glucose management in the critically ill patients. Novel technological approaches such as a continuous glucose monitoring system (CGMS) might help to overcome some problems of tight glucose control by reducing the risk of hypoglycemia and minimizing glycemic variability.

ABSTRACT

PURPOSE: Combination therapy of alpha-blockers and 5alpha-reductase inhibitors (5-ARIs) is widely used for the treatment of benign prostatic hyperplasia (BPH). We aimed to study the effect on prostate volume and symptoms of shifting to monotherapy in patients who previously received a combination therapy. MATERIALS AND METHODS: A prospective study was conducted of 60 patients who were diagnosed with BPH. Patients were aged 45 years or older and had a prostate volume of 30 cc or more, International Prostate Symptom Score (IPSS) of 12 or above, maximal flow rate (Qmax) of 15 ml/s or less, and prostate-specific antigen (PSA) level of less than 10 ng/ml. The patients initially received a combination therapy of doxazosin 4 mg/day and finasteride 5 mg/day for 3 months and were then randomly assigned to receive monotherapy for 3 months. The factors were then compared. RESULTS: A total of 30 patients were assigned to doxazosin (group 1) and 30 to finasteride (group 2) after the combination therapy. The percentage changes in prostate volume, IPSS, and Qmax during the period from post-combination therapy to post-monotherapy were not significantly different between the two groups (p=0.052, 0.908, 0.081), whereas PSA significantly decreased in group 2 (p<0.001). IPSS was not significantly different at post-combination therapy and at post-monotherapy in both groups (p=0.858, 0.071). The prostate volume significantly increased from 40.97 cc at post-combination therapy to 44.29 cc at post-monotherapy in group 1 (p=0.001) and insignificantly increased from 38.32 cc to 38.61 cc in group 2 (p=0.696). CONCLUSIONS: Although the duration of drug administration was short in this study, 5-ARI monotherapy could maintain the alleviated symptoms and reduce the risk of acute urinary retention and surgery due to prostate regrowth in BPH patients whose symptoms improved with combination therapy.

ABSTRACT

BACKGROUND/AIMS: Thyrotropin (TSH)-secreting pituitary adenoma (TSHoma) is rare and represents 1~2% of all pituitary adenomas. TSHoma should be distinguished from the thyroid hormone resistance syndrome. Patients with TSHoma may be misdiagnosed with primary hyperthyroidism and often receive inappropriate thyroid gland treatment. METHODS: We assessed the clinical characteristics of patients with TSHoma who presented to Severance Hospital at the Yonsei University College of Medicine, Seoul, Korea between 2005 and 2009. RESULTS: Of 484 patients who underwent pituitary tumor resection, eight (1.65%; five women and three men) were found to have TSHoma. The mean age was 40.6+/-8.9 years at diagnosis (range, 28~55 years). The median duration from onset of symptoms to diagnosis was 17 months (range, 4~60 months). Four patients had overt symptoms of hyperthyroidism and two had visual field defect. Six patients had elevated free thyroxine (FT4) levels with elevated or inappropriately normal TSH levels, and two patients had symptoms associated with Hashimoto's thyroiditis. The serum levels of free alpha-subunit measured in two patients were elevated. Six of the tumors were macroadenomas (>10 mm) and two were microadenomas. Complete tumor removal was achieved in all patients. Five patients had preoperative anterior pituitary dysfunction; three patients recovered from this after surgery. Three patients were lost to follow up and five patients showed no evidence of recurrence or hyperthyroidism in the follow-up period (mean, 30.8 months, range, 3~57). CONCLUSIONS: Early diagnosis and complete removal of the tumor mass may improve the neurological and endocrine deficits.

ABSTRACT

Thyrotropin (TSH)-secreting pituitary adenoma is a very rare disease. In one-quarter of patients suffering from this disease, the pituitary tumor secretes other anterior pituitary hormones. Herein, we report a case of pituitary adenoma with simultaneous secretion of TSH and growth hormone (GH). A 34-year-old female visitied local hospital complaining of sweating, intermittent palpitation, and weight loss of 8 kg within 1 year. The patient had undergone trans-sphenoidal surgery 3 years prior for resolution of a TSH and GH co-secreting pituitary adenoma. She had been administered somatostatin analogue prior to visiting our hospital. The patient's GH levels were suppressed to below 1 ng/mL on the 75 g oral glucose tolerance test, and her basal insulin-like growth factor-I (IGF-I) level was within normal range. Thyroid function tests demonstrated increased levels of both free thyroxine and TSH. Sella-MRI revealed pituitary adenoma at the floor of the pituitary fossa, approximately 2 cm in height. Therefore, she was diagnosed with residual TSH-secreting pituitary adenoma. The patient again underwent trans-sphenoidal surgery and entered complete remission, based on hormone levels and MRI findings.

ABSTRACT

BACKGROUND: Non-functioning pituitary adenomas (NFPAs) are characterized by the absence of clinical and biochemical evidence of pituitary hormone hypersecretion, and these tumors constitute approximately one third of all the tumors of the anterior pituitary. Recently, hormonal deficiencies have gradually evolved to become the leading presenting signs and symptoms in patients with NFPAs. We investigated pituitary hormonal insufficiencies according to the magnetic resonance imaging (MRI) findings in patients with NFPA. METHODS: We evaluated the patients who were newly diagnosed with NFPA from 1997 through 2009. Among them, we analyzed 387 patients who were tested for their combined pituitary function and who underwent MRI. The severity of the hypopituitarism was determined by the number of deficient axes of the pituitary hormones. On the MRI study, the maximal diameter of the tumor, Hardy's classification, the thickness of the pituitary gland and the presence of stalk compression were evaluated. RESULTS: The mean age was 46.85 +/- 12.93 years (range: 15-86) and 186 patients (48.1%) were male. As assessed on MRI, the tumor diameter was 27.87 +/- 9.93 mm, the thickness of the normal pituitary gland was 1.42 +/- 2.07 mm and stalk compression was observed in 201 patients (51.9%). Hypopituitarism was observed in 333 patients (86.0%). Deficiency for each pituitary hormone was most severe in the patients with Hardy type IIIA. Hypopituitarism was severe in the older age patients (P = 0.001) and the patients with a bigger tumor size (P < 0.001) and the presence of stalk compression (P < 0.001). However, the patients who had a thicker pituitary gland showed less severe hypopituitarism (P < 0.001). Multivariate analysis showed that age, tumor diameter and the thickness of pituitary gland were important determinants for pituitary deficiency (P = 0.004, P < 0.001, P = 0.022, respectively). CONCLUSION: The results suggest that the hormonal deficiencies in patient with NFPA were correlated with the MRI findings, and especially the tumor diameter and preservation of the pituitary gland.

ABSTRACT

Septic arthritis of the sternoclavicular joint is a rare condition. The predisposing risk factors include intravenous drug abuse, subclavian vein catheter placement, diabetes mellitus and trauma. Delayed or inadequate management can lead to irreversible joint damage with subsequent disability, even death. We report a 48-year-old female patient who presented with right sternoclavicular joint swelling and right shoulder pain. Magnetic resonance imaging of the sternum showed swelling of the right sternoclavicular joint with gadolinium enhancement. Synovial fluid and bone tissue culture revealed Escherichia coli (E.coli), and confirmed the diagnosis of sternoclavicular septic arthritis. She was successfully treated with surgical debridement and ciprofloxacin without recurrence. This is the first case report of E.coli sternoclavicular septic arthritis in Korea.

ABSTRACT

PURPOSE: To investigate the short-term safety of antidiuretic hormone in elderly patients with nocturnal polyuria, focus on hyponatremia and others electrolytes disturbances and to assess short-term effects on nocturnal urine output and number of nocturnal voids. METHODS: Between June 2005 and August 2006, a total of 34 patients with nocturnal polyuria were orally administered 0.2 mg desmopressin tablet at bedtime for two weeks. Serum sodium, others electrolytes, urine sodium and urine osmolarity were assessed in the third days, one week and two weeks after treatment with desmopressin and compared adult group ( or =65 years of age). We assessed the effect of desmopressin using a frequency-volume charts and analysed. RESULTS: In total 34 patients (20 adult, 14 elderly) were analyzed. Desmopressin treatment did not significantly change serum and urine electrolytes include soduim concentration in elderly patients comparied with adult patients. Serum sodium concentration below normal range was recorded in 2 patients in elderly group, but no serious adverse events occurred and recovered without sequelae. The mean number of nocturnal voids decresed (54% reduction) and nocturnal urine output decreased (57% reduction) after using desmopressin. CONCLUSIONS: Desmopressin was well tolerated and effective in elderly patients with nocturnal polyuria without clinically significant hyponatremia.
