The goal of this study is to test the antecedents of overall attitudes toward sunless tanning product use. The data collected from 302 US female college students with an average age of 20.11 were included in the analysis. A structural equation modeling was performed to test the hypothesized relationships. The results revealed that body surveillance and social ostracism influenced the individuals’ cutaneous body image dissatisfaction, which also influenced perceived attractiveness and fitness of tanned appearance. Perceived tanning attractiveness and perceived tanning physical fitness positively influences attitudes toward tanning product use. It is evident that seeing one’s own body through the lens of others is at the root of positive attitudes toward sunless tanning products. Positive attitudinal changes toward sunless tanning products can be successfully established emphasizing sunless tanning products as fashion consumption. The findings in this study have important relevance, in that tanning products can be marketed as cosmetic appearance-enhancement products for people to look attractive, toned, and fit.

In this study, we analyzed the characteristics of atmospheric stability to investigate local environment change at an atomic power plant in Gori region. The used data was obtained from field observation of major meteorological variables such as wind direction and speed, air temperature, relative humidity, and solar radiation using AWS (Automatic Weather System) in Gori region from February to September in 2003. As a result, when strong northerly winds (more than 4~6 m/s) and weak northwesterly winds (2~3m/s) blow, atmospheric stability was neutral and stable from winter to spring, respectively. Atmospheric stability (neutral) in summer was similar to that in two other seasons (winter and spring), but it was stable for weak southwesterly winds (2~3 m/s). Finally, atmospheric stability was neutral for strong winds (over 4~6 m/s) in fall without respect to wind direction, while that was stable for very weak winds (less than 2 m/s).

Purpose: This study was conducted to investigate the extent of diffusion of Intravenous infusion nursing practice guideline among nurses in advanced general hospitals and general hospitals in Korea. Methods: The subjects were 234 nurses who practice the intravenous infusion in 24 advanced general hospitals and general hospitals. Data were collected between October 5 and November 2, 2015 by mail (return rates: 97.5 %). Data were analyzed using descriptive statistics, t-test, and ANOVA with SPSS/ WIN 21. Results: The average guideline diffusion score and levels of diffusion was 3.39±0.58 (level of “use sometimes”). 44 recommendations (46%) were in level of “use always” and 50 recommendations (53%) were in “use sometimes”. Extent of diffusion were significantly different according to present status (F=2.81, p=.040) and education (F=4.35, p=.014). The facilitating factors to use the guideline were education by department of nursing service, convenient composition of guideline and barrier factors were “no time to use the guideline”, “don’t know the guideline” and “there is no guideline at ward”. Conclusion: Extent of diffusion of Intravenous infusion nursing practice guideline among nurses was moderate level. The strategies for promoting the implementation of guideline in clinical practice is needed. Further study of outcome evaluation of guideline implementation will be needed.

Background Tissue expansion is an effective and valuable technique for the reconstruction of large skin lesions and scars. This study aimed to evaluate the applicability and safety of a newly designed skin expanding bioreactor system for maximizing the graft area and minimizing the donor site area. Methods A computer-controlled biaxial skin bioreactor system was used to expand skin in two directions while the culture media was changed daily. The aim was to achieve an expansion speed that enabled the skin to reach twice its original area in two weeks or less. Skin expansion and subsequent grafting were performed for 10 patients, and each patient was followed for 6 months postoperatively for clinical evaluation. Scar evaluation was performed through visual assessment and by using photos. Results The average skin expansion rate was $10.54%{\pm}6.25%$; take rate, $88.89%{\pm}11.39%$; and contraction rate, $4.2%{\pm}2.28%$ after 6 months. Evaluation of the donor and recipient sites by medical specialists resulted in an average score of 3.5 (out of a potential maximum of 5) at 3 months, and 3.9 at 6 months. The average score for patient satisfaction of the donor site was 6.2 (out of a potential maximum of 10), and an average score of 5.2 was noted for the recipient site. Histological examination performed before and after the skin expansion revealed an increase in porosity of the dermal layer. Conclusions This study confirmed the safety and applicability of the in vitro skin bioreactor, and further studies are needed to develop methods for increasing the skin expansion rate.

The most significant risk factor for hepatocellular carcinoma (HCC) is the presence of cirrhosis or advanced fibrosis of the liver. Liver biopsy was traditionally considered the gold standard for assessing the liver fibrosis burden. Recently, non-invasive methods, particularly transient elastography (TE), have proven effective at measuring fibrosis and determining cirrhosis. Clinical application of TE ranges from measuring fibrosis to predicting long-term prognosis and treatment response. Here, we focus on recent studies on the prognostic value of TE for predicting HCC.

Background/Aims: The histologic status of the immune-tolerant (IT) phase of chronic hepatitis B relative to long-term outcomes is unclear. This study aimed to discover how the serological criteria currently in use correspond to histologic criteria in determining the IT phase and indication for liver biopsy. Methods: Patients in the serological IT phase determined by positive hepatitis B e antigen, hepatitis B virus (HBV) DNA ≥106 IU/mL, and normal or minimally elevated alanine aminotransferase (ALT) ≤60 IU/L, who underwent liver biopsy at three different hospitals were included. The distribution of the histologic IT phase, defined as fibrosis of stage 1 or less and inflammation of grade 1 or less, was compared with that of the serological IT phase. The risk factors for the incidence of liver-related events, such as hepatocellular carcinoma, liver cirrhosis, liver transplantation, and death, were also analyzed. Results: Eighty-two (31.7%) out of 259 clinically suspected IT phase patients belonged to the histologic IT phase. Age over 35, high AST, and low albumin were useful for ruling out the histologic IT phase. Risk factors predicting liver-related events were age and significant fibrosis stage. There was no significant difference in the proportion of histologic IT phase and clinical prognosis between normal ALT and mildly elevated ALT groups. However, even in patients with normal ALT, age was an important factor in predicting the presence of the histologic IT phase. Conclusions: A significant number of patients who belonged to the serological IT phase were not in the histologic IT phase. Patients over 35 years and those with high AST, low albumin, and low HBV DNA levels were more likely to experience poor long-term clinical outcomes. Therefore, additional histologic assessment should be considered.

Aims: Patient of liver cirrhosis have an increased risk of in-hospital mortality after surgery. However, large-scale studies on the prognosis after surgery in these patients are lacking. This study investigated the in-hospital mortality after surgery in patients with liver cirrhosis in current 5 years. Methods: We used the Health Insurance Review and Assessment Service-National Patient Samples (HIRA-NPS) between 2012 and 2016. In-hospital mortality and hospital stay were analyzed using the data. Mortality rates according to the surgical department were also analyzed. Results: Of the 1,662,887 patients who underwent surgery, 16,174 patients (1.0%) patients had cirrhosis. In-hospital mortality was significantly higher in patients with cirrhosis than without cirrhosis (8.0% vs. 1.0%). In addition, total hospitalization period (22.6 days vs. 10.2 days) and use of intensive care unit (24.3% vs. 4.8%) were significantly higher in patients with liver cirrhosis. In-hospital mortality after surgery in cirrhotic patients was highest in the otorhinolaryngology surgery (15.7%), followed by neurosurgery (14.8%), thoracic and cardiovascular surgery (13.2%) and plastic surgery (10.2%) compared to the patients without cirrhosis. Conclusions: Patients with cirrhosis have a significantly higher risk of in-hospital mortality after surgery. A new predictive scoring system for predicting postoperative mortality in these patients is needed.
Recent research trends and updates on nonalcoholic fatty liver disease
Jeong-Ju Yoo,김원,Moon Young Kim,김상균,Jong Eun Yeon,이진우,조용균,Sang Hoon Park,Joo Hyun Sohn,KASL-KNSG 대한간학회 2019 Clinical and Molecular Hepatology(대한간학회지) Vol.25 No.1
Nonalcoholic fatty liver disease (NAFLD), together with metabolic syndrome and obesity, has shown a rapid increase in prevalence worldwide and is emerging as a major cause of chronic liver disease and liver transplantation. Among the various phenotypes of NAFLD, nonalcoholic steatohepatitis (NASH) is highly likely to progress to development of endstage liver disease and cardiometabolic disease, resulting in liver-related and non-liver–related mortality. Nonetheless, there is no standardized pharmacotherapy against NASH and many drugs are under development in ongoing clinical trials. To develop a successful anti-NASH drug, it is necessary to select an appropriate target population and treatment outcomes depending on whether the mode of action is anti-metabolic, anti-inflammatory or anti-fibrotic. Recently, innovative surrogate markers have been investigated to replace hard outcomes such as liver histology and mortality and reduce the clinical trial duration. Currently, several drugs with fast track designation are being tested in phase III clinical trials, and many other drugs have moved into phase II clinical trials. Both lean NAFLD and typical obese NAFLD have been extensively studied and genetic variants such as PNPLA3 and TM6SF2 have been identified as significant risk factors for lean NAFLD. In the near future, noninvasive biomarkers and effective targeted therapies for NASH and associated fibrosis are required to develop precision medicine and tailored therapy according to various phenotypes of NAFLD.
