It is inconvenient to perform serum lipid analysis in fasting state in diabetic patients with drug treatment. In patients with statin treatment and Asian diet, it has not been clearly known whether non-fasting values could be used for the clinical decision making in diabetic patients. In this study, fasting and post-prandial plasma lipid profiles of hospitalized type 2 diabetic patients taking statin, were measured in whom standard diabetic breakfast in traditional Korean style were provided. In repeated-measures ANOVA, there were no significant differences among fasting, post-prandial 2 and 4 hr low-density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol values. When compared to fasting levels, both post-prandial 2 hr and 4 hr LDL cholesterol levels were misclassified as not achieved target goal only in 4% of patients. Post-prandial HDL cholesterol matched with fasting values in women, without exception. In conclusion, the fasting and post-prandial LDL and HDL cholesterol levels are not significantly different each other and can be used in the assessment of achieving target goal in type 2 diabetes taking statin after Korean diet.

Purpose: Cystoscopy is the most common procedure used to diagnose urological diseases; however, it is invasive and can be associated with pain and anxiety. Although pain relieving medications, such as lidocaine lubricants, are used during cystoscopy, the procedure still causes discomfort. Therefore, non-medical intervention is needed to reduce pain and anxiety during the procedure and increase patient satisfaction. The aim of this study was to evaluate the effect of heating therapy on pain, anxiety, physiologic measures, and satisfaction during cystoscopy. Methods: This was a single-blinded, single-center, randomized controlled trial. A total of 145 participants who underwent cystoscopy between August 2017 and October 2017 were recruited and randomly assigned to an experimental or control group. Before and after cystoscopy, all the participants self-reported the degree of pain they felt, while pain was objectively assessed by trained nurses. Anxiety was evaluated using the validated Korean version of the State-Trait Anxiety Inventory. Blood pressure and pulse rate were also recorded as physiologic measures. After cystoscopy, satisfaction was measured in the experimental group only using the Korean version of the Client Satisfaction Questionnaire. Results: Heating therapy reduced both subjective and objective pain and anxiety in the experimental group compared to the control group. Heating therapy also decreased the systolic and diastolic blood pressure and pulse rate in the experimental group compared to the control group. Women reported significantly greater satisfaction than men. Conclusion Heating therapy during cystoscopy is a convenient and effective nursing intervention that decreases pain and anxiety and enhances patient satisfaction.

BACKGROUND: Epstein-Barr Virus (EBV) is one of the most prevalent causes of viral infection in humans. EBV infection stage (acute, past, or absent infection) is typically determined using a combination of assays that detect EBV-specific markers, such as IgG and IgM antibodies against the EBV viral capsid antigen (VCA) and IgG antibodies against the EBV nuclear antigen (EBNA). We compared the diagnostic performance and agreement of results between three commercial EBV antibody assays using an EBV performance panel (SeraCare Life Science, Milford, MA, USA) as a reference. METHODS: EBV antibody tests of EBV VCA IgM, VCA IgG, and EBNA IgG antibodies were performed by the Architect (Abbott Diagnostics, Wiesbaden, Germany), Liaison (DiaSorin, Saluggia, Italy), and Platelia (Bio-Rad, Marnes-la-Coquette, France) assays. Agreement between the three assays was evaluated using 279 clinical samples, and EBV DNA and antibody test results were compared. RESULTS: The three EBV antibody assays showed good diagnostic performance with good and excellent agreement with the performance panel (kappa coefficient, >0.6). The overall VCA IgM positivity rate was higher in EBV DNA-positive samples than in EBV DNA-negative samples for all three EBV antibody assays (P=0.02). The three EBV antibody assays exhibited good agreement in results for the clinical samples. CONCLUSIONS: The diagnostic performance of the three EBV antibody assays was acceptable, and they showed comparable agreement in results for the clinical samples.

This study aimed to examine the relationship between nutrition intake and estimated glomerular filtration rate (eGFR) indicating kidney function in Korean individuals without diabetes or cardiovascular disease. Study participants from the Korea National Health and Nutrition Examination Survey 2013–2014 (n = 4,378, 30–65 years) were classified by their eGFR levels (mL/min/1.732 m²): ≥ 120 (n = 299), 119–105 (n = 789), 104–90 (n = 1,578), 89–60 (n = 1,685), < 60 (n = 27). After adjusted for confounding factors (age, sex, cigarette smoking, alcohol drinking, total caloric intake [TCI], income status, education level, body mass index, and physical activity), blood pressure, low-density lipoprotein (LDL) cholesterol, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, fasting glucose, and glycated hemoglobin were higher, and high density lipoprotein cholesterol levels were lower in participants with lower eGFR levels than those with higher eGFR levels. n-3 fatty acid (FA) and n-6 FA (% of TCI/day) intake were also significantly higher in participants with higher eGFR levels than in those with lower eGFR levels. Based on the above results, participants were subdivided into 3 groups according to n-6 FA intake levels (Q1: ≥ 2.93%, n = 1,462; Q2: 2.92%–1.88%, n = 1,463; Q3: < 1.88%, n = 1,453). People consuming higher n-6 FAs, particularly the Q1 group showed higher eGFR levels and lower levels of LDL cholesterol and creatinine. In conclusion, higher intake of n-6 FAs within the range of dietary reference may be beneficial to maintain healthy kidney function.

BACKGROUND: Epstein-Barr virus (EBV) is known to be the causative agent of infectious mononucleosis and EBV-related malignancies. In this study, we compared the results of three real-time PCR kits for EBV DNA assays. METHODS: A total of 300 whole blood samples submitted for quantitative EBV PCR between January 2013 and September 2014 at Severance Hospital were included. The samples were tested by using the Artus EBV RG PCR Kit (Qiagen, Germany), AccuPower EBV Quantitative PCR Kit (Bioneer, Korea), and Real-Q EBV Kit (BioSewoom, Korea). Samples with discordant results between the three kits were confirmed by direct sequencing. RESULTS: The result concordance rate and kappa coefficient (K) were 86.3% and 0.69 for Artus-AccuPower, 93.3% and 0.85 for Artus-Real-Q, and 92.3% and 0.83 for AccuPower-Real-Q, respectively. The correlations between the three kits were found to be significant, with a correlation coefficient of r=0.854 for Artus-AccuPower, -0.802 for Artus-Real-Q, and -0.977 for AccuPower-Real-Q, respectively (P<0.0001). If the real-time PCR concordant results of 258 samples and the direct sequencing results of 42 real-time PCR discordant samples were assumed to be true, the sensitivity/specificity values were 0.921/0.976 for Artus, 0.902/0.965 for AccuPower, and 0.967/1.000 for Real-Q. CONCLUSIONS: The three real-time PCR kits showed excellent sensitivities and specificities. All these kits would be acceptable for clinical and therapeutic management of EBV. However, some discordant results between the kits indicate the need for caution in clinical diagnosis and staging. Further implementation of standardized methodology would be needed for EBV DNA assays.

We report a case of a 14-year-old Korean boy presenting with pain in the left lower quadrant, persisting for over 10 days. Except for the persistent pain, no other symptoms, such as vomiting and diarrhea, were observed. In addition, laboratory findings were normal. He was eventually diagnosed with epiploic appendagitis, a rare disease in children. This case highlights the need for imaging study for early diagnosis of epiploic appendagitis or surgical emergencies in children who visit emergency departments with pain in the left lower quadrant without specific clinical findings.

Objective: The purpose of this study was to investigate the effects of depressive symptoms on health-seeking behaviors using the large epidemiological study data of the Korea National Health and Nutrition Examination (KNHANES). Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHANES), which is a large-scale national survey, were used in this study. The Patient Health Questionnaire-9 (PHQ-9) was used to assess the depressive state of the participants. Specialized self-reported questionnaires that included questions about health-seeking behaviors were also performed. To examine the relationships between depression and health-seeking behaviors, complex sample logistic regression models with control for covariates were used. Results: There was a significant association between decreased health-seeking behaviors and depressive symptoms in adults (odds ratio [OR]: 3.11, 95% confidence interval [CI]: 2.44–3.96). The association was found to be especially strong in males (OR: 2.63, 95% CI: 1.69–4.10) versus in females (OR: 2.49, 95% CI: 1.90–3.27). With regard to age group, younger adults (19–44 years of age) showed the highest OR (OR: 3.07, 95% CI: 2.12–4.45). Conclusion Our findings support the idea that there is a significant association between health-seeking behaviors and depressive symptoms in the Korean population. These results suggest that individuals with decreased health-seeking behaviors could be evaluated for depressive symptoms.

The evaluation of menopausal status is an important subject in the field of treatment of hormone receptor positive breast cancer. According to the menopausal status, endocrine therapy should be categorized by individual patient. However, the gonadal injury caused by various therapeutic drugs and its recovery would confuse the interpretation of clinical and biological markers for ovarian reserve. There are some methods to examine the functional ovarian reserve indirectly. Ultrasonography for counting follicles is a relatively reliable procedure, although it is not feasible because of time-labor consumption and high cost. Biological marker from blood samples such as serum follicle stimulating hormone (FSH), serum estradiol (E2), serum inhibin, or anti-Müllerian hormone (AMH) would be a better choice. The examination of serum FSH and E2 is already recommended as biomarkers for measuring functional ovarian reserve in many guidelines. However, there are limitation of serum FSH and E2 in patients with chemotherapy-induced amenorrhea and treated by tamoxifen. AMH is promising biomarker in the field of infertility treatment even in the patients treated by chemotherapy. It might be a possible biomarker to determine the menopausal status for decision-making whether aromatase inhibitor could be applicable or not in hormone positive breast cancer patients with chemotherapy induced amenorrhea or treated by tamoxifen.

Mitochondrial morphology is dynamically regulated by forming small, fragmented units or interconnected networks, and this is a pivotal process that is used to maintain mitochondrial homeostasis. Although dysregulation of mitochondrial dynamics is related to the pathogenesis of several human diseases, its molecular mechanism is not fully elucidated. In this study, we demonstrate the potential role of miR-27 in the regulation of mitochondrial dynamics. Mitochondrial fission factor (MFF) mRNA is a direct target of miR-27, whose ectopic expression decreases MFF expression through binding to its 3'-untranslated region. Expression of miR-27 results in the elongation of mitochondria as well as an increased mitochondrial membrane potential and mitochondrial ATP level. Our results suggest that miR-27 is a novel regulator affecting morphological mitochondrial changes by targeting MFF.

BACKGROUND: Omega-3 fatty acids derived from fish oil have been reported to exert a beneficial effect on reducing cardiovascular disease. Reports about their mechanism have generated several interesting findings, including a change in small dense low density lipoprotein (sdLDL) cholesterol proportion, adiponectin, and apolipoprotein B (apoB), in addition to changes in the lipid profile. The principal objective of our study was to evaluate the effects of omega-3 fatty acids on plasma sdLDL, adiponectin, apoB100, and B48 in type 2 diabetic patients with hypertriglyceridemia. METHODS: We randomized 28 type 2 diabetic patients in a placebo-controlled, double-blind trial to receive either omega-3 fatty acids or placebo, both administered at a dose of 4 g daily for 12 weeks. LDL subfractions prior to and after treatment were separated via low-speed ultracentrifugation and analyzed via immunoelectrophoresis. Adiponectin, apoB100, and B48 levels were measured using an ELISA kit. RESULTS: sdLDL proportions were reduced in the omega-3 fatty acids group by 11% after 12 weeks of treatment (n = 17, P = 0.001), and were reduced by 4% in the control group (n = 11, P = 0.096). The patients receiving the omega-3 fatty acids evidenced a significant reduction in the levels of triglyceride (P = 0.001), apoB100, and B48 after 12 weeks (P = 0.038 and P = 0.009, respectively) relative to the baseline. Omega-3 fatty acids supplementation increased fasting blood glucose (P = 0.011), but the levels of HbA1c in each group did not change to a statistically significance degree. The adiponectin value was not reduced in the omega-3 fatty acids group (P = 0.133); by way of contrast, the placebo group evidenced a significant reduction in adiponectin value after 12 weeks (P = 0.002). CONCLUSION: Omega-3 fatty acid treatment proved effective in the reduction of atherogenic sdLDL and apoB in type 2 diabetic patients (Clinical trials reg. no. NCT 00758927, clinicaltrials.gov).
