PURPOSE: The purpose of this study was to examine the relationship between body esteem, stress, and health promoting behaviors among Korean adults in a community and to identify factors that influence health promoting behaviors. METHODS: This study was conducted using a questionnaire which included item for body esteem, stress and health promotion behaviors. Data were collected from 257 adults living in Jeollabuk-do in Korea from November to December, 2015. The collected data were analyzed through descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression using the SPSS/WIN 21.0 program. RESULTS: The mean score of body esteem was 2.73±0.43, stress was 1.89±0.68, and health promoting behaviors was 2.22±0.45. There was a significant positive correlation between body esteem and health promotion behaviors (r=.47, p<.001), whereas there was a significant negative correlation between stress and health promotion behaviors (r=-.47, p<.001). In stepwise multiple regression analysis, body esteem, religion, education explained approximately 30.1% of health promoting behaviors (F=37.73, p<.001). CONCLUSION: The results in this study indicate that body esteem is the most important factor in health promoting behaviors among Korean adults. Thus, body esteem contents should be included in developing programs for adults to enhance their health promoting behaviors.

F-box proteins, consisting of 69 members which are organized into the three subclasses FBXW, FBXL, and FBXO, are the substrate specific recognition subunits of the SKP1-Cullin 1-F-box protein E3 ligase complex. Although βTrCP 1 and 2, members of the FBXW subfamily, are known to regulate some protein stability, molecular mechanisms by which these proteins can recognize proper substrates are unknown. In this study, it was found that βTrCP1 showed strong interaction with members of mitogen-activated protein kinases. Although extracellular signal-regulated kinase (ERK) 3, p38β, and p38δ showed weak interactions, ERK2 specifically interacted with βTrCP1 as assessed by immunoprecipitation. In interaction domain determination experiments, we found that ERK2 interacted with two independent ERK docking sites located in the F-box domain and linker domain, but not the WD40 domain, of βTrCP1. Notably, mutations of βTrCP1 at the ERK docking sites abolished the interaction with ERK2. βTrCP1 underwent phosphorylation by EGF stimulation, while the presence of the mitogen-activated protein kinase kinases inhibitor U0126, genetic silencing by sh-ERK2, and mutation of the ERK docking site of βTrCP1 inhibited phosphorylation. This inhibition of βTrCP1 phosphorylation resulted in a shortened half-life and low protein levels. These results suggest that ERK2-mediated βTrCP1 phosphorylation may induce the destabilization of βTrCP1.

BACKGROUND: Computed tomography (CT) is commonly used to evaluate the degree of sinus involvement in cases of inverted papilloma (IP). However, CT cannot differentiate tumor from adjacent inflammatory mucosa or retained secretions. By contrast, magnetic resonance imaging (MRI) has been reported to be useful in distinguishing IP from paranasal sinusitis. This study investigated whether preoperative assessment with MRI and CT accurately predict the extent of IP. MATERIALS AND METHODS: CT and MRI were retrospectively reviewed in 9 cases of IP. Patients were categorized into stages based on CT and MRI findings, according to the staging system proposed by Krouse. The involvement of IP in each sinus was also assessed. RESULTS: Differentiation of IP from inflammatory disease may be more successful in routine cases where the inflammatory mucosa has low signal intensity on T1-weighted images and very high signal intensity on T2-weighted images. CT imaging could not differentiate tumor from adjacent inflammatory mucosa or retained secretions. CONCLUSION: Preoperative MRI of IP can predict the location and extent of the tumor involvement in the paranasal sinuses and sometimes predicts malignant changes.

BACKGROUND AND OBJECTIVES : Facial palsy of herpes zoster oticus has rapid onset, is usually severe in degree, and poorer in prognosis than Bell's palsy. In the past, herpes zoster oticus has usually been treated with acyclovir and steroid, but recently, applying stellate ganglion block for herpes zoster oticus has been recognized as an additional treatment that may improve facial palsy. This study was designed to evaluate the effect of stellate ganglion block on herpes zoster oticus. Subjects and METHOD : We reviewed retrospectively the medical records of 30 patients with herpes zoster oticus who were treated with acyclovir, steroid and stellate ganglion block between January 1995 and December 2004. The follow-up period was at least over than 6 months. RESULTS : All patients suffered from otalgia, vesicle, and facial palsy. The average degree of House-Brackmann classification on admission was 3.26 in the complete recovery patients and 4.61 in the incomplete recovery patients. Seventeen patients were completely recovered from facial palsy (56.7%), and 13 showed residual facial palsy 13 patients(43.3%). The poor prognosis may be related with early onset of facial palsy, high degree of House-Brackmann classification on admission and high degenerative ratio on electroneurography of facial nerve. CONCLUSION : The additional treatment of stellate ganglion block in herpes zoster oticus may not be effective on improving the complete recovery rate and prognosis.

PURPOSE: The aims of this study were to evaluate the change of [18F]fluoromisonidazole ([18F]FMISO) uptake in C3H mouse squamous cell carcinoma-VII (SCC-VII) treated with mild hyperthermia (42oC) and nicotinamide and to assess the biodistribution of the markers in normal tissues under similar conditions. METHODS AND MATERIALS: [18F]FMISO was producedby our hospital. Female C3H mice with a C3H SCC-VII tumor grown on their extremities were used. Tumors were size matched. Non-anaesthetized, tumor-bearing mice underwent control or mild hyperthermia at 42oC for 60 min with nicotinamide (50 mg/kg i.p. injected) and were examined by gamma counter, autoradiography and animal PET scan 3 hours after tracer i.v. injected with breathing room air. The biodistribution of these agents were obtained at 3 h after [18F]FMISO injection. Blood, tumor, muscle, heart, lung, liver, kidney, brain, bone, spleen, and intestine were removed, counted for radioactivity and weighed. The tumor and liver were frozen and cut with a cryomicrotome into 10-micrometer sections. The spatial distribution of radioactivity from the tissue sections was determined with digital autoradiography. RESULTS: The mild hyperthermia with nicotinamide treatment had only slight effects on the biodistribution of either marker in normal tissues. We observed that the whole tumor radioactivity uptake ratios were higher in the control mice than in the mild hyperthermia with nicotinamide treated mice for [18F]FMISO (1.56+/-1.03 vs. 0.67+/-0.30; p=0.063). In addition, autoradiography and animal PET scan demonstrated that the area and intensity of [18F]FMISO uptake was significantly decreased. CONCLUSION: Mild hyperthermia and nicotinamide significantly improved tumor hypoxia using [18F]FMISO and this uptake reflected tumor hypoxic status.

Gastroesophageal reflux disease (GERD) is a condition in which gastric contents regurgitate into the esophagus or beyond, resulting in either troublesome symptoms or complications. GERD is heterogeneous in terms of varied manifestations, test findings, and treatment responsiveness. GERD diagnosis can be established with symptomatology, pathology, or physiology. Recently the Lyon consensus defined the “proven GERD” with concrete evidence for reflux, including advanced grade erosive esophagitis (Los Angeles classification grades C and or D esophagitis), long-segment Barrett’s mucosa or peptic strictures on endoscopy or distal esophageal acid exposure time > 6% on 24-hour ambulatory pH-impedance monitoring. However, some Asian researchers have different opinions on whether the same standards should be applied to the Asian population. The prevalence of GERD is increasing in Asia. The present evidence-based guidelines were developed using a systematic review and meta-analysis approach. In GERD with typical symptoms, a proton pump inhibitor test can be recommended as a sensitive, cost-effective, and practical test for GERD diagnosis.Based on a meta-analysis of 19 estimated acid-exposure time values in Asians, the reference range upper limit for esophageal acid exposure time was 3.2% (95% confidence interval, 2.7-3.9%) in the Asian countries. Esophageal manometry and novel impedance measurements, including mucosal impedance and a post-reflux swallow-induced peristaltic wave, are promising in discrimination of GERD among different reflux phenotypes, thus increasing its diagnostic yield. We also propose a long-term strategy of evidence-based GERD treatment with proton pump inhibitors and other drugs.

Background and Objectives: Angiographic assessment of coronary stenosis severity using quantitative coronary angiography (QCA) is often inconsistent with that based on fractional flow reserve (FFR) or intravascular ultrasound (IVUS). We investigated the incidence of discrepancies between QCA and FFR or IVUS, and the outcomes of FFR- and IVUS-guided strategies in discordant coronary lesions. Methods: This study was a post-hoc analysis of the FLAVOUR study. We used a QCA-derived diameter stenosis (DS) of 60% or greater, the highest tertile, to classify coronary lesions as concordant or discordant with FFR or IVUS criteria for percutaneous coronary intervention (PCI). The patient-oriented composite outcome (POCO) was defined as a composite of death, myocardial infarction, or revascularization at 24 months. Results: The discordance rate between QCA and FFR or IVUS was 30.2% (n=551). The QCAFFR discordance rate was numerically lower than the QCA-IVUS discordance rate (28.2% vs. 32.4%, p=0.050). In 200 patients with ≥60% DS, PCI was deferred according to negative FFR (n=141) and negative IVUS (n=59) (15.3% vs. 6.5%, p<0.001). The POCO incidence was comparable between the FFR- and IVUS-guided deferral strategies (5.9% vs. 3.4%, p=0.479).Conversely, 351 patients with DS <60% underwent PCI according to positive FFR (n=118) and positive IVUS (n=233) (12.8% vs. 25.9%, p<0.001). FFR- and IVUS-guided PCI did not differ in the incidence of POCO (9.5% vs. 6.5%, p=0.294). Conclusions The proportion of QCA-FFR or IVUS discordance was approximately one third for intermediate coronary lesions. FFR- or IVUS-guided strategies for these lesions were comparable with respect to POCO at 24 months.
