Understanding the attitudes toward sunless tanning product use: implication of tanning product consumption

Jeong‑Ju Yoo,Hyeon Jeong Cho 한국의류학회 2018 Fashion and Textiles Vol.5 No.1

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.

Objective: Fitz-Hugh-Curtis syndrome (FHCS) is characterized by perihepatitis in patients with pelvic inflammatory disease. Hepatic capsular enhancement in arterial phase of abdominal computed tomography (CT) is usually required for definite diagnosis. The objective of this study was to assess clinical significance of intensity of hepatic capsular enhancement in CT of patients with FHCS. Methods: A total of 86 patients who had hepatic capsular enhancement in CT due to FHCS were retrospectively enrolled. The hepatic capsular enhancement was divided into three patterns according to the intensity of enhancement by an expert radiologist: A, partial weak enhancement; B, partial strong or diffuse weak enhancement; and C, diffuse strong enhancement. Other clinical and laboratory parameters such as duration of admission were also evaluated. Results: Hepatic capsular enhancement in CT was classified into pattern A (n=28), pattern B (n=35), and pattern C (n=23). Hospital stay was significantly shorter in pattern A (6.1±2.4 days, P<0.001) than that in pattern B (7.2±2.9 days) or pattern C (7.7±2.2 days). Subjective perihepatic pain duration was well correlated with the degree of hepatic capsular enhancement (P<0.001). In multivariate analysis, the intensity of capsular enhancement was significantly associated with hospital stay after adjusting other factors. However, laboratory inflammation marker was not directly correlated with hepatic capsular enhancement. Conclusion: Enhancement pattern of CT scan in patients with FHCS is closely related to its clinical severity and the course of this disease.

BACKGROUND/OBJECTIVES: To evaluate the nutritional status and prevalence of malnutrition in hospitalized children at admission and during hospitalization in South Korea. SUBJECTS/METHODS: This first cross-sectional nationwide “Pediatric Nutrition Day (pNday)” survey was conducted among 872 hospitalized children (504 boys, 368 girls; 686 medical, 186 surgical) from 23 hospitals in South Korea. Malnutrition risk was screened using the Pediatric Yorkhill Malnutrition Score (PYMS) and the Screening Tool Risk on Nutritional status and Growth. Nutritional status was assessed by z-scores of weight-for-age for underweight, weight-for-height for wasting, and height-for-age for stunting as well as laboratory tests. RESULTS: At admission, of the 872 hospitalized children, 17.2% were underweight, and the prevalence of wasting and stunting was 20.2% and 17.3%, respectively. During hospitalization till pNday, 10.8% and 19.6% experienced weight loss and decreased oral intake, respectively. During the aforementioned period, fasting was more prevalent in surgical patients (7.5%) than in medical patients (1.6%) (P < 0.001). According to the PYMS, 34.3% and 30% of the children at admission and on pNday, respectively, had a high-risk of malnutrition, requiring consultation with the nutritional support team (NST). However, only 4% were actually referred to the NST during hospitalization. CONCLUSIONS: Malnutrition was prevalent at admission and during hospitalization in pediatric patients, with many children experiencing weight loss and poor oral intake. To improve the nutritional status of hospitalized children, it is important to screen and identify all children at risk of malnutrition and refer malnourished patients to the multidisciplinary NST for proper nutritional interventions.

Aims: Tenofovir disoproxil fumarate (TDF) is the most potent nucleoside analog for the treatment of chronic hepatitis B virus (HBV) infection. Genotypic resistance to tenofovir has not yet been reported. This study aimed to characterise HBV mutations that confer tenofovir resistance. Methods: Two consecutive patients with viral breakthrough during treatment with TDF-containing regimens were prospectively enrolled. The gene encoding HBV reverse transcriptase (RT) was sequenced. Nine HBV clones harbouring a series of mutations in the RT gene were constructed by site-directed mutagenesis. Drug susceptibility of each clone was determined by Southern blot analysis and real-time PCR. Relative frequency of mutants were evaluated by ultra-deep sequencing. Results: (Please understand that actual mutation site numbers were replaced by bold, underlined alphabetical letters since they are now confidential due to embargo policy.) Seven mutations (rtSaaaC [C], rtHbbbY [Y], rtDcccE [E], rtVdddL, rtLeeeM, rtMfffV, and rtLgggI) were commonly found in viral isolates from both patients after viral breakthrough; C, Y, and E were novel mutations. An HBV mutant harbouring all three mutations (CYE) was resistant to tenofovir. The IC₅₀ values for wild-type HBV and the CYE mutant were 3·8 ± 0·6 μM and 14·1 ± 1·8 μM, respectively. Ultra-deep sequencing showed that CYE mutant was dominant than any other mutant in both patients. All tenofovir-resistant mutants had similar susceptibility to a core inhibitor, NVR 3-778 (IC₅₀ < 0·4 μM) compared with wild-type (IC₅₀ = 0·4). Conclusions: Our study reveals that a novel triple mutation (CYE) is associated with tenofovir-resistance. These results demonstrate that tenofovir-resistant HBV mutants can emerge, although the genetic barrier is high. A novel core inhibitor might be a potential rescue therapy for tenofovir-resistant HBV.

Background/Aims: The controlled attenuation parameter (CAP), based on transient elastography, is widely used for noninvasive assessment of the degree of hepatic steatosis (HS). We investigated the correlation of the degree HS between CAP and ultrasound (US) in patients with HS. Methods: In total, 986 patients with US-based HS who underwent transient elastography within 1 month were evaluated. The US-based grade of HS was categorized as mild (grade 1), moderate (grade 2), or severe (grade 3). Results: The CAP was significantly correlated with the US-based grade of HS (r = 0.458, p < 0.001). The median CAP value of each US-based HS grade showed a positive correlation with grade (271.1, 303.7, and 326.7 dB/m for grades 1, 2, and 3). In a multivariate analysis, the US-based HS grade, body mass index, serum albumin, alanine aminotransferase, and total cholesterol, and liver stiffness were all significantly correlated with the CAP value (all p < 0.05). The areas under the receiver operating characteristic curves for grade 2 to 3 and grade 3 HS were 0.749 (95% confidence interval [CI], 0.714 to 0.784) and 0.738 (95% CI, 0.704 to 0.772). The optimal cut-off CAP values to maximize the sum of the sensitivity and specificity for grade 2 to 3 and grade 3 HS were 284.5 dB/m (sensitivity 78.6%, specificity 61.7%) and 298.5 dB/m (sensitivity 84.6%, specificity 55.6%). Conclusions: The correlation of the degree of HS between CAP and US was significantly high in patients with HS, and the optimal cut-off CAP values for grade 2 to 3 and grade 3 HS were 284.5 and 298.5 dB/m.

( Jeong-ju Yoo ),( Eun Ju Cho ),( Bora Lee ),( Sang Gyune Kim ),( Young Seok Kim ),( Yun Bin Lee ),( Jeong-hoon Lee ),( Su Jong Yu ),( Yoon Jun Kim ),( Jung-hwan Yoon ) 대한소화기학회 2018 Gut and Liver Vol.12 No.6

Background/Aims: Recently reported prognostic models for primary biliary cholangitis (PBC) have been shown to be effective in Western populations but have not been wellvalidated in Asian patients. This study aimed to compare the performance of prognostic models in Korean patients and to investigate whether inflammation-based scores can further help in prognosis prediction. Methods: This study included 271 consecutive patients diagnosed with PBC in Korea. The following prognostic models were evaluated: the Barcelona model, the Paris-I/II model, the Rotterdam criteria, the GLOBE score and the UK-PBC score. The neutrophil-to-lymphocyte ratio (NLR) was analyzed with reference to its association with prognosis. Results: For predicting liver transplant or death at the 5-year and 10-year follow-up examinations, the UK-PBC score (areas under the receiver operating characteristic curve [AUCs], 0.88 and 0.82) and GLOBE score (AUCs, 0.85 and 0.83) were significantly more accurate in predicting prognosis than the other scoring systems (all p< 0.05). There was no significant difference between the performance of the UK-PBC and GLOBE scores. In addition to the prognostic models, a high NLR ( >2.46) at baseline was an independent predictor of reduced transplant-free survival in the multivariate analysis (adjusted hazard ratio, 3.74; p<0.01). When the NLR was applied to the prognostic models, it significantly differentiated the prognosis of patients. Conclusions: The UK-PBC and GLOBE scores showed good prognostic performance in Korean patients with PBC. In addition, a high NLR was associated with a poorer prognosis. Including the NLR in prognostic models may further help to stratify patients with PBC. (Gut Liver 2018;12:714-721)

Acute kidney injury in patients with acute-on-chronic liver failure: clinical significance and management

( Jeong-ju Yoo ),( Moo Yong Park ),( Sang Gyune Kim ) 대한신장학회 2023 Kidney Research and Clinical Practice Vol.42 No.3

Acute-on-chronic-liver failure (ACLF) refers to a phenomenon in which patients with chronic liver disease develop multiple organ failure due to acute exacerbation of underlying liver disease. More than 10 definitions of ACLF are extant around the world, and there is lack of consensus on whether extrahepatic organ failure is a main component or a consequence of ACLF. Asian and European consortiums have their own definitions of ACLF. The Asian Pacific Association for the Study of the Liver ACLF Research Consortium does not consider kidney failure as a diagnostic criterion for ACLF. Meanwhile, the European Association for the Study of the Liver Chronic Liver Failure and the North American Consortium for the Study of End-stage Liver Disease do consider kidney failure as an important factor in diagnosing and assessing the severity of ACLF. When kidney failure occurs in ACLF patients, treatment varies depending on the presence and stage of acute kidney injury (AKI). In general, the diagnosis of AKI in cirrhotic patients is based on the International Club of Ascites criteria: an increase of 0.3 mg/dL or more within 48 hours or a serum creatinine increase of 50% or more within one week. This study underscores the importance of kidney failure or AKI in patients with ACLF by reviewing its pathophysiology, prevention methods, and treatment approaches.
