BACKGROUND/OBJECTIVES:
The extract from Dendropanax morbifera exhibited diverse therapeutic potentials. We aimed to evaluate the efficacy and safety of D. morbifera leaf extract for improving metabolic parameters in human.
SUBJECTS/METHODS:
A 12-week, double blind, placebo-controlled and randomized trial included a total of 74 adults, and they were assigned to the placebo group (n = 38) or 700 mg/day of D. morbifera group (n = 36). The efficacy endpoints were changes in glycemic, lipid, obesity, and blood pressure (BP) parameters, in addition to the prevalence of metabolic syndrome (MetS) and the numbers of MetS components. Safety was assessed by monitoring adverse events (AEs).
RESULTS:
After 12 weeks of treatment, the hemoglobin A1c (HbA1c) level significantly decreased in the D. morbifera group compared to that of the placebo group (difference: −0.13 ± 0.20% vs. 0.00 ± 0.28%, P = 0.031; % of change: −2.27 ± 3.63% vs. 0.10 ± 5.10%, P = 0.025). The homeostatic model assessment for insulin resistance level also decreased significantly from its baseline in the D. morbifera group. The systolic BP of D. morbifera group decreased significantly than that of placebo group (difference: −3.9 ± 9.8 mmHg vs. 3.3 ± 11.7 mmHg, P = 0.005; % of change: −2.8 ± 7.7% vs. 3.3 ± 10.2%, P = 0.005). However, the lipid parameters and body composition including body weight did not differ between the groups. The prevalence of MetS (36.8% vs. 13.9%, P = 0.022) and the incidence of MetS (10.5% vs. 13.9%, P = 0.027) at 12 weeks was significantly lower in the D. morbifera group than it was in the placebo group. No serious AEs occurred in either group.
CONCLUSIONS
Supplementation with D. morbifera extracts over a 12-week period improved metabolic parameters such as HbA1c and BP and reduced the prevalence of MetS.

This study used data from the Korea National Health and Nutrition Examination Survey IV–VII from 2007 to identify the prevalence of obesity and its phenotypes (metabolically unhealthy obesity [MUO] and metabolically healthy obesity [MHO]) and their secular changes. The prevalence of obesity in Korea increased with significant secular changes observed (β=0.326, P trend <0.01) between 2007 and 2017, and especially in men (β=0.682, P trend <0.001) but not in women. The changes in the prevalence of obesity during the study period were different between men and women (P=0.001). The prevalence of MUO significantly increased only in men (β=0.565, P trend <0.01), while that of MHO increased only in women (β=0.179, P<0.05), especially in the younger age group (β=0.308, P<0.01).

Background:
Fatty liver and/or increased liver enzyme values have been reported to be associated with incident diabetes. We sought to determine whether increased visit-to-visit liver enzyme variability is associated with incident diabetes.
Methods:
Study participants were recruited from the Korean Genome and Epidemiologic Study (KoGES). A total of 4,151 people aged 40 to 69 years was recruited and tested every 2 years for up to 12 years. Visit-to-visit aspartate aminotransferase (AST) and alanine aminotransferase (ALT) variability was evaluated in first the 6-year period through the use of various variability measurements: standard deviation (SD), average successive variability, coefficient of variation (CV), and variation independent of mean (VIM). Oral glucose tolerance test was performed at every visit.
Results:
During the 6-year follow‐up appointments, 13.0% (538/4,151) of people developed incident diabetes. Visit-to-visit AST variability was associated with an increased risk of diabetes independent of conventional risk factors for diabetes (hazard ratio per 1-SD increment [95% confidence interval]: 1.06 [1.00 to 1.11], 1.12 [1.04 to 1.21], and 1.13 [1.04 to 1.22] for SD, CV, and VIM, respectively; all P<0.05); however, no such associations were observed in the visit-to-visit ALT variability. According to alcohol consumption status, both AST and ALT variability were independent predictors for incident diabetes in subjects with heavy alcohol consumption; however, neither AST nor ALT variability was associated with diabetes risk in subjects who did not drink alcohol heavily.
Conclusion
Visit-to-visit liver enzyme variability is an independent predictor of incident diabetes. Such association was more evident in those who consumed significant amounts of alcohol.

Scrub typhus develops after the individual is bitten by a trombiculid mite infected with Orientia tsutsugamushi. Since it has been reported that pneumonia is frequently observed in patients with scrub typhus, we investigated whether intranasal (i.n.) vaccination with the outer membrane protein of O. tsutsugamushi (OMPOT) would induce a protective immunity against O. tsutsugamushi infection. It was particular interest that when mice were infected with O. tsutsugamushi, the bacteria disseminated into the lungs, causing pneumonia. The i.n. vaccination with OMPOT induced IgG responses in serum and bronchoalveolar lavage (BAL) fluid. The anti-O. tsutsugamushi IgA Abs in BAL fluid after the vaccination showed a high correlation of the protection against O. tsutsugamushi. The vaccination induced strong Ag-specific Th1 and Th17 responses in the both spleen and lungs. In conclusion, the current study demonstrated that i.n. vaccination with OMPOT elicited protective immunity against scrub typhus in mouse with O. tsutsugamushi infection causing subsequent pneumonia.

BACKGROUND: The apolipoprotein B/A1 (apoB/A1) ratio is a stronger predictor of future cardiovascular disease than is the level of conventional lipids. Statin and ezetimibe combination therapy have shown additional cardioprotective effects over statin monotherapy. METHODS: This was a single-center, randomized, open-label, active-controlled study in Korea. A total of 36 patients with type 2 diabetes mellitus were randomized to either rosuvastatin monotherapy (20 mg/day, n=20) or rosuvastatin/ezetimibe (5 mg/10 mg/day, n=16) combination therapy for 6 weeks. RESULTS: After the 6-week treatment, low density lipoprotein cholesterol (LDL-C) and apoB reduction were comparable between the two groups (−94.3±15.4 and −62.0±20.9 mg/dL in the rosuvastatin group, −89.9±22.7 and −66.8±21.6 mg/dL in the rosuvastatin/ezetimibe group, P=0.54 and P=0.86, respectively). In addition, change in apoB/A1 ratio (−0.44±0.16 in the rosuvastatin group and −0.47±0.25 in the rosuvastatin/ezetimibe group, P=0.58) did not differ between the two groups. On the other hand, triglyceride and free fatty acid (FFA) reductions were greater in the rosuvastatin/ezetimibe group than in the rosuvastatin group (−10.5 mg/dL [interquartile range (IQR), −37.5 to 29.5] and 0.0 µEq/L [IQR, −136.8 to 146.0] in the rosuvastatin group, −49.5 mg/dL [IQR, −108.5 to −27.5] and −170.5 µEq/L [IQR, −353.0 to 0.8] in the rosuvastatin/ezetimibe group, P=0.010 and P=0.049, respectively). Both treatments were generally well tolerated, and there were no differences in muscle or liver enzyme elevation. CONCLUSION: A 6-week combination therapy of low-dose rosuvastatin and ezetimibe showed LDL-C, apoB, and apoB/A1 ratio reduction comparable to that of high-dose rosuvastatin monotherapy in patients with type 2 diabetes mellitus. Triglyceride and FFA reductions were greater with the combination therapy than with rosuvastatin monotherapy.

BACKGROUND: Hand eczema is one of the most common skin disorders and negatively affects quality of life. However, a large-scale multicenter study investigating the clinical features of patients with hand eczema has not yet been conducted in Korea. OBJECTIVE: To identify the prevalence of various hand diseases, which is defined as all cutaneous disease occurring in hands, and to investigate the clinical features of patients with hand eczema and the awareness about hand eczema in the general population and to compare the prevalence of hand eczema between health care providers and non-health care providers. METHODS: To estimate the prevalence of hand diseases, we analyzed the medical records of patients from 24 medical centers. Patients were assessed by online and offline questionnaires. A 1,000 from general population and 913 hand eczema patients answered the questionnaire, for a total of 1,913 subjects. RESULTS: The most common hand disease was irritant contact dermatitis. In an online survey, the lifetime prevalence of hand eczema was 31.2%. Hand eczema was more likely to occur in females (66.0%) and younger (20~39 years, 53.9%). Health care providers and housewives were the occupations most frequently associated with hand eczema. Winter (33.6%) was the most common season which people experienced aggravation. The 63.0% and 67.0% answered that hand eczema hinders their personal relationship and negatively affects daily living activities, respectively. CONCLUSION: Hand eczema is a very common disease and hinders the quality of life. The appropriate identification of hand eczema is necessary to implement effective and efficient treatment.

BACKGROUND: S100A8 is differentially expressed in various cell types and is associated with a number of malignant disorders. S100A8 may affect tumor biology. However, its role in cutaneous squamous cell carcinoma (SCC) is not well established. OBJECTIVE: This study aims to investigate the relationship between S100A8 and cutaneous SCC development. METHODS: We performed immunohistochemical staining to detect S100A8 expression in facial skin specimens of premalignant actinic keratosis (AK), malignant SCC, and normal tissues. In addition, we utilized postconfluence and high calcium-induced differentiation in a culture system model. Furthermore, we constructed a recombinant adenovirus expressing GFP-tagged S100A8 to investigate the role of S100A8 in SCC cell differentiation. RESULTS: S100A8 was significantly overexpressed in human cutaneous SCC compared to that in normal and AK tissues. S100A8 was gradually upregulated in SCC cells in a post-confluence-induced differentiation model. Overexpression of S100A8 in SCC cells induced by adenoviral transduction led to increased expression levels of differentiation markers, such as loricrin, involucrin, and filaggrin. S100A8 overexpression also increased loricrin and involucrin luciferase activity. CONCLUSION: S100A8 regulates cutaneous SCC differentiation and induces well-differentiated SCC formation in skin.

Orbital and paranasal actinomycosis have not been commonly reported. We report a case of this uncommon infection, which was improved after endonasal endoscopic drainage and antibiotics. A 53-year-old woman with type 2 diabetes mellitus complained of inability to lift her right upper eyelid and painful swelling over the preceding two days. Broad-spectrum antibiotics did not resolve her lesion. In ophthalmic examination, decreased visual acuity, upper and medial gaze limitation, and a relative afferent pupillary defect of her right eye were observed. Computed tomography of the orbit showed aggravated orbital cellulitis, preseptal cellulitis, subperiosteal abscess, and maxillary and ethmoid sinusitis. After endonasal endoscopic drainage and systemic antibiotics, her clinical symptoms dramatically improved. Microbiological analysis of the maxillary excisional biopsy showed Actinomycosis. This case is of interest due to the rare orbital presentation of actinomycosis infection and the importance of appropriate surgical drainage and long-term antibiotics treatment in such cases. Because delayed diagnosis and treatment of rhino-orbital actinomycosis can cause permanent vision loss or intracranial abscess, it requires careful clinical attention.

Carbohydrates are a primary source of energy and a major component of the structure of living things-; there are many different kinds. As eating behavior is a part of life, it was usually not described in addiction. However, sometimes it seems aspects of addiction. This eating behavior can also appear with regard to other food. A bio-psycho-social model is required for complex analysis of addiction. When highly addictive agents are excluded, we can usually identify a key factor related to the vulnerability of the individual to addictive behavior. Considering that every source of happiness can potentially lead to addictive behaviors, we need to be cautious about the controlling. Not every carbohydrate can be connected with addictive behavior. Addictive behavior could be associated with a variety of ingredients other than carbohydrates. Until recently, sweet substances were thought to be the primary culprit behind addictive behavior. It is necessary to identify the food component or other factors associated with a specific craving. A multidimensional approach to the psychology of addictive behaviors might be more useful than opposing carbohydrate consumption in general.

The leading cause of morbidity and mortality in patients with acromegaly is cardiovascular complications. Myocardial exposure to excessive growth hormone can cause ventricular hypertrophy, hypertension, arrhythmia, and diastolic dysfunction. However, congestive heart failure as a result of systolic dysfunction is observed only rarely in patients with acromegaly. Most cases of acromegaly exhibit high levels of serum insulin-like growth factor-1 (IGF-1). Acromegaly with normal IGF-1 levels is rare and difficult to diagnose. Here, we report a rare case of an acromegalic patient whose first clinical manifestation was severe congestive heart failure, despite normal IGF-1 levels. We diagnosed acromegaly using a glucose-loading growth hormone suppression test. Cardiac function and myocardial hypertrophy improved 6 months after transsphenoidal resection of a pituitary adenoma.
