BACKGROUND: This study was done to examine the impact of diabetes fear of self-injecting (FSI) and fear of self-testing (FST) on glycemic control and diabetes self-management. METHODS: A questionnaire survey was performed in the form of one-on-one interviews with 100 insulin-treated diabetic patients. The questions included subject traits, FSI/FST, and confidence in diabetes self-care (CIDS). Glycemic control was determined by the measurement of glycated hemoglobin (Hemoglobin A1C). RESULTS: The patients who did not have a spouse and were less well educated showed high FSI/FST scores and low CIDS scores. The patients who had taken high quantities of insulin, had diabetes related complications, and performed self-monitoring of blood glucose less frequently showed high FSI/FST scores. The patients who had received diabetes education, possessed glucometer and performed self-monitoring of blood glucose frequently had high CIDS scores. High FSI/FST scores were positively related to each other, negatively related to low CIDS scores and not significantly related to Hemoglobin A1C. On the other hand, a significant correlation was seen between CIDS scores and Hemoglobin A1C. CONCLUSION: High levels of FSI and/or FST were associated with high diabetes-related distress, poor general well-being, and psychologic comorbidity as well as poorer adherence to the diabetes treatment regimen. It is important in diabetes care to lower injection-related fears and improve diabetes self-management through systematic desensitization, relaxation therapy, the use of pen-type injection device, and proper education such as insulin injection amount adjustment, properties of insulin, and the risk of hypoglycemia for the patients and their families.

Choledochoscopic lithotomy with the aid of electrohydraulic lithotripsy ( EHL ) was performed in 12 patients at the Department of Surgery, College of Medicine, the Catholic University of Korea, St. Vincent Hospital between January 1996 and March 1998. This retrospective analysis include 4 patients with common bile duct (CBD) stones, 5 patients with intrahepatic duct (IHD) stones, and 3 patients with CBD & IHD stones. The male to female ratio was 1 to 2. The peak incidence of age was the fifty. As a route for the choledochoscopy, a T-tube tract was used in 9 patients, while percutaneous biliary drainage followed by dilatation of the tract was established in 3 patients. The largest stones measured 22mm (by 5mm), the average is 10.3mm. Average number of session which performed for IHD stones was 3.7, while that of CBD stones was 2.7. Complete removal of the stones was achieved in 7 of 12 patients. Retained stones of CBD were removed completely in all cases. We could not removed retained stones completely in cases of multiple, impacted stones in peripheral ducts, associated stricture and acute angulation of IHD & CHD which choledochoscopic manipulation make difficult. Minor complications were bleeding from the bile duct mucosa in 1 patient and postprocedure chills and fever in 1 patient. In conclusion, choledochoscopic lithotomy with electrohydraulic lithotripsy is efficient and will be useful to remove biliary calculi in patients who have poor surgical risks.

PURPOSE: Many patients with benign prostatic hyperplasia (BPH) have not only voiding symptoms but also storage symptoms. Despite the many types of treatment that have been developed for BPH, storage symptoms persist. We conducted an assessment of the efficacy of transurethral resection of the prostate (TURP) and the change in the International Prostate Symptoms Score (IPSS) storage sub-score after the procedure according to prostate size in patients with BPH. MATERIALS AND METHODS: Men aged 50 years or older who had BPH were enrolled in this study. 186 patients were divided into two groups according to prostate size measuring using transrectal ultrasonography: In group 1, prostate size was less than 30 ml (51 patients), and in group 2, prostate size was greater than 30 ml (135 patients). All of the patients underwent TURP. We examined whether the degree of change in the IPSS, voiding symptoms, storage symptoms, and quality of life (QoL) differed before and after TURP and according to prostate size. RESULTS: After three months of TURP, the subjects in both groups showed significant improvement in the IPSS, voiding symptoms, storage symptoms, QoL, and maximum flow rate (p<0.05). The scores for the IPSS, voiding symptoms, storage symptoms, and QoL of group 1 and 2 after three months of TURP were 16.36, 14.25 (p=0.233), 8.21, 8.24 (p=0.980), 8.11, 5.16 (p=0.014), 2.89, and 2.10 (p=0.030), respectively. CONCLUSIONS: TURP is an effective treatment for patients with BPH, regardless of prostate size. However, while the improvement in the storage symptoms of patients with a prostate size of less than 30 ml was not significant, it was in patients with a prostate size greater than 30 ml.

BACKGROUND: Although ganglionated plexi (GPs) are important in the pathogenesis of arrhythmia, their patterns of atrial innervation have remained unclear. We investigated patterns of GP innervation to cardiac atria and the neuroanatomical interconnections among GPs in an animal model. METHODS: Atrial innervation by GPs was evaluated in 10 mongrel dogs using a retrograde neuronal tracer (cholera toxin subunit B [CTB] conjugated with fluorescent dyes). In Experiment 1, CTB was injected into the atria. In Experiment 2, CTB was injected into the major GP, including the anterior right GP (ARGP), inferior right GP (IRGP), superior left GP (SLGP), and ligament of Marshall (LOM). After 7 days, the GPs were examined for the presence of tracer-positive neurons. RESULTS: GPs in either right or left-side were innervating to both the same and opposite sides of the atrium. In quantitative analysis, right-sided GPs, especially ARGP, showed numerical predominance in atrial innervation. Based on the proportion of CTB-labeled ganglion in each GP, atrial innervation by GPs showed a tendency of laterality. In Experiment 2, CTB that was injected to a particular GP widely distributed in different GP. ARGP projected the largest number of innervating neurons to the IRGP, SLGP and LOM. CONCLUSION: This study demonstrated that GPs project axons widely to both the same and opposite sides of atria. ARGP played a dominant role in atrial innervation. Furthermore, there were numerous neuroanatomical interconnections among GPs. These findings about neuronal innervation and interconnections of GPs could offer useful information for understanding intrinsic cardiac nervous system neuroanatomy.

Purpose: The objective of this study was to identify the factors influencing maternal identity in pregnant women. Methods: Using a descriptive research design, a cross-sectional survey was conducted. In total, 127 pregnant women were recruited from a tertiary hospital in Korea from January to April 2019. Measurements included maternal identity, stress, depression, spousal and familial support, and demographic and obstetric characteristics. Data were analyzed by descriptive statistics, the independent t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression using SPSS version 25.0. Results: The mean score for maternal identity was 131.15 out of 160, and the mean scores for stress, depression, and spousal and familial support were 14.59 (out of 40), 6.82 (out of 30), and 109.04 (out of 132), respectively. Stress (r=–.38, p<.001), depression (r=–.37, p<.001), and spousal and familial support (r=.37, p<.001) were significantly correlated with maternal identity. In multiple regression analysis, stress (β=–0.27, p=.005) and spousal and familial support (β=0.23, p=.014) were found to be significant factors influencing maternal identity in pregnant women (F=14.17, p<.001). Conclusion It is necessary to develop effective strategies to mitigate stress and to encourage spousal and familial support in pregnant women. Such strategies could further enable pregnant women to enhance their maternal identity.

In order to assess inhibitory potentials of white rose petal extracts (WRPE) on the activities of enzymes related to dermal aging according to the extraction conditions, three extraction methods were adopted. WRPE was prepared by extracting dried white rose (Rosa hybrida) petals with 50% ethanol (WRPE-EtOH), Pectinex(R) SMASH XXL enzyme (WRPE-enzyme) or high temperature-high pressure (WRPE-HTHP). In the inhibition of matrix metalloproteinase-1, although the enzyme activity was fully inhibited by all 3 extracts at 100 microg/mL in 60 min, partial inhibition (50-70%) was achieved only by WRPE-EtOH and WRPE-enzyme at 50 microg/mL. High concentrations (> or =250 microg/mL) of all 3 extracts markedly inhibited the elastase activity. However, at low concentrations (15.6-125 microg/mL), only WRPE-EtOH inhibited the enzyme activity. Notably, WRPE-EtOH was superior to WRPE-enzyme and WRPE-HTHP in the inhibition of tyrosinase. WRPE-EtOH significantly inhibited the enzyme activity from 31.2 microM, reaching 80% inhibition at 125 microM. In addition to its strong antioxidative activity, the ethanol extract of white rose petals was confirmed to be effective in inhibiting skin aging-related enzymes. Therefore, it is suggested that WRPE-EtOH could be a good candidate for the improvement of skin aging such as wrinkle formation and pigmentation.

BACKGROUND: We investigated the protective effects of propofol in the HK-2 cell line of human kidney proximal tubular cells against hydrogen peroxide (H2O2)-induced oxidative stress. METHODS: After pretreatment with different concentrations of propofol (0 microM, 10 microM, 25 microM and 50 microM) for 30 minutes, HK-2 cells were exposed to 8 mM H2O2 for 4 hours. Cell death was assessed by measuring the percentage of lactate dehydrogenase (LDH) release and by counting viable cells. The nature of cell death was assessed by doubles-taining cells with fluorescein isothiocyanate-labeled Annexin V and propidium iodide, and then analyzing the cells using flow cytometry. RESULTS: After exposure to 8 mM H2O2 for 4 hours, the percentage of LDH release was 45.1 +/- 4.2% and the number of viable HK-2 cells was 5.2 +/- 6.0%. Pretreatment with propofol suppressed H2O2-induced LDH release in a concentration-dependent manner, reducing the percentage of LDH release to 38.1 +/- 5.6%, 33.5 +/- 6.3%, and 26.2 +/- 3.8% of the controls at 10 microM, 25 microM and 50 microM propofol, respectively. Numbers of viable cells increased following propofol pretreatment, with 11.4 +/- 10.9%, 19.5 +/- 16.1%, and 32.4 +/- 23.3% cell survival rates after pretreatment with 10 microM, 25 microM and 50 microM propofol, respectively. Analyses of flow cytometry showed that the propofol pretreatment decreased the percentage of necrotic and late apoptotic cells. CONCLUSIONS: Propofol protects HK-2 human kidney proximal tubular cells against H2O2-induced oxidative stress.

Purpose: The expression of major histocompatibility complex class I (MHC I) has previously been reported to be negatively associated with estrogen receptor (ER) expression. Furthermore, MHC I expression, level of tumor-infiltrating lymphocytes (TILs), and expression of interferon (IFN) mediator MxA are positively associated with one another in human breast cancers. This study aimed to investigate the mechanisms of association of MHC I with ER and IFN signaling. Materials and Methods: The human leukocyte antigen (HLA)-ABC protein expression was analyzed in breast cancer cell lines. The expressions of HLA-A and MxA mRNAs were analyzed in MCF-7 cells in Gene Expression Omnibus (GEO) data. ER and HLA-ABC expressions, Ki-67 labeling index and TIL levels in tumor tissue were also analyzed in ER+/ human epidermal growth factor receptor 2 (HER2)- breast cancer patients who randomly received either neoadjuvant chemotherapy or estrogen modulator treatment followed by resection. Results: HLA-ABC protein expression was decreased after β-estradiol treatment or hESR-GFP transfection and increased after fulvestrant or IFN-γ treatment in cell lines. In GEO data, HLA-A and MxA expression was increased after ESR1 shRNA transfection. In patients, ER Allred score was significantly lower and the HLA-ABC expression, TIL levels, and Ki-67 were significantly higher in the estrogen modulator treated group than the chemotherapy treated group. Conclusion MHC I expression and TIL levels might be affected by ER pathway modulation and IFN treatment. Further studies elucidating the mechanism of MHC I regulation could suggest a way to boost TIL influx in cancer in a clinical setting.
