Abstract
Mitochondrial dysfunction has been implicated in Parkinson's Disease (PD) progression; however, the mitochondrial factors underlying the development of PD symptoms remain unclear. One candidate is CR6-interacting factor1 (CRIF1), which controls translation and membrane insertion of 13 mitochondrial proteins involved in oxidative phosphorylation. Here, we found that CRIF1 mRNA and protein expression were significantly reduced in postmortem brains of elderly PD patients compared to normal controls. To evaluate the effect of Crif1 deficiency, we produced mice lacking the Crif1 gene in dopaminergic neurons (DAT-CRIF1-KO mice). From 5 weeks of age, DAT-CRIF1-KO mice began to show decreased dopamine production with progressive neuronal degeneration in the nigral area. At ~10 weeks of age, they developed PD-like behavioral deficits, including gait abnormalities, rigidity, and resting tremor. L-DOPA, a medication used to treat PD, ameliorated these defects at an early stage, although it was ineffective in older mice. Taken together, the observation that CRIF1 expression is reduced in human PD brains and deletion of CRIF1 in dopaminergic neurons leads to early-onset PD with stepwise PD progression support the conclusion that CRIF1-mediated mitochondrial function is important for the survival of dopaminergic neurons.

Abstract
Button mushrooms (Agaricus bisporus), are one of the most widely consumed mushrooms in the world. However, changes within its microbial community as it relates to the use of different raw materials and cultivation methods, as well as potential points of microbial contamination throughout the production process have not been investigated extensively. In the present study, button mushroom cultivation was investigated in each of the four stages (raw materials, composting (phase I, Ⅱ, and Ⅲ), casing, and harvesting), and samples (n = 186) from mushrooms and their related environments were collected from four distinct mushroom-growing farms (A-D) in Korea. Shifts within the bacterial consortium during mushroom production were characterized with 16 S rRNA amplicon sequencing. The succession of bacterial communities on each farm was dependent on the raw material incorporated, aeration, and the farm environment. The dominant phyla of the compost stack at the four farms were Pseudomonadota (56.7%) in farm A, Pseudomonadota (43.3%) in farm B, Bacteroidota (46.0%) in farm C, and Bacillota (62.8%) in farm D. During the Phase Ⅰ, highly heat-resistant microbes, such as those from the phylum Deinococcota (0.6-65.5%) and the families Bacillaceae (1.7-36.3%), Thermaceae (0.1-65.5%), and Limnochordaceae (0.3-30.5%) greatly proliferated. The microbial diversity within compost samples exhibited a marked decline as a result of the proliferation of thermophilic bacteria. In the spawning step, there were considerable increases in Xanthomonadaceae in the pasteurized composts of farms C and D - both of which employed an aeration system. In the harvesting phase, beta diversity correlated strongly between the casing soil layer and pre-harvest mushrooms, as well as between gloves and packaged mushrooms. The results suggest that gloves may be a major source of cross-contamination for packaged mushrooms, highlighting the need for enhanced hygienic practices during the harvesting phase to ensure product safety. These findings contribute to the current understanding of the influence of environmental and adjacent microbiomes on mushroom products to benefit the mushroom industry and relevant stakeholders by ensuring quality production.

Type of funding sources: None.
Background
Recently, as cumulative exposure of lipids for a lifetime has become important to prevent and predict atherosclerotic cardiovascular disease (ASCVD), it is recommended to obtain the optimal lipid levels from a young age. However, questions remain regarding the vascular changes in young adulthood by nonoptimal lipid levels.
Purpose
We aimed to investigate the progression of coronary artery calcification (CAC) according to lipid profiles in Korean young adults.
Methods
From the KOrea Initiative on Coronary Artery calcification registry, we collected 2,940 statin-naïve adults under 45-year-old, undergoing serial coronary artery calcium scans for the purpose of routine health check-ups between 2002 and 2017. CAC progression was assessed according to the optimality of lipid levels and each lipid variable.
Results
In this cohort (mean age, 41.3 years; man 82.4%), only 477 subjects (16.2%) had the optimal lipid profile, defined as triglycerides <150 mg/dl, LDL cholesterol <100 mg/dl, and HDL cholesterol ≥45 mg/dl. During follow-up (median 39.7 months), CAC progression was observed in 438 participants (14.8%) and more frequent in nonoptimal lipid group (16.5% vs 5.9%; p<0.001). Nonoptimal lipid levels during young adulthood increased the risk of CAC progression after adjusting for other cardiovascular risk factors (adjusted HR, 2.36; p=0.001), with a stepwise risk increase according to lipid levels. In particular, in the subjects with an initial calcium score of zero (adjusted HR, 2.13; p=0.014), those in their 20s or 30s (adjusted HR 2.70; p=0.029), and those without any other risk factors (adjusted HR 2.51; p=0.025), deemed as very low-risk groups, nonoptimal lipid levels more than doubled the risk of CAC progression, respectively. Among lipid variables, high triglycerides appeared to provide the greatest impact on CAC progression of young adults.
Conclusions
The proportion of young adults with optimal lipid levels was lower than expected. Nonoptimal lipid level was significantly associated with the risk of CAC progression in young adults, even with low-risk. Triglycerides had the strongest association with the risk of CAC progression. Screening and intervention for nonoptimal lipid levels, particularly triglycerides, from an early age might be of clinical value.

Abstract
BACKGROUND During the coronavirus disease 2019 (COVID-19) pandemic, various adverse skin reactions to long-term mask wearing have been reported. AIM To assess the clinical features of mask-induced dermatoses and to recommend prevention and treatment options. METHODS From April to August 2020, questionnaires including topics such as demographic information, pre-existing skin disorders, reported mask-related symptoms, daily mask-wearing duration and frequency, types of masks used and whether the participant was a healthcare worker, were distributed to patients in 12 hospitals. Dermatologists assessed skin lesions, confirmed diagnosis and recorded treatments. RESULTS Itchiness was the most frequent symptom, mostly affecting the cheeks. The most common skin disease was new-onset contact dermatitis (33.94%), followed by new-onset acne (16.97%) and worsening of pre-existing acne (16.97%). Daily wearing of masks was significantly (P = 0.02) associated with new-onset contact dermatitis. More than half of patients with pre-existing skin problems experienced disease worsening while wearing masks. Longer duration of wearing (> 6 h/day, P = 0.04) and use of cotton masks (P < 0.001) significantly increased acne flare-up. Healthcare workers had a higher incidence of skin disease. Skin lesions were generally mild and well tolerated with topical treatment. The study had some limitations: the effect of seasonal characteristics and other risk factors were not assessed, and the patients were visiting dermatological clinics and had interest in their skin status, thus, there may have been selection bias. CONCLUSION Mask-induced/-triggered dermatoses contribute to increase the dermatological burden during the pandemic.

Abstract
Skin necrosis is one of the most severe complications following filler injections, and can result in permanent aesthetic defects. Although an increasing number of studies have addressed the management of dermal filler complications, no study has described the spectrum of microbial pathogens. The aim of this study was to delineate the bacterial profile and prognostic factors of filler-related skin necrosis by reviewing the clinical and microbiological features of these patients. A retrospective medical record review of patients undergoing treatment for skin necrosis induced by fillers was conducted. In total, 10 cases were identified, with injection sites being the nasolabial fold (70%; n = 7), nasal dorsum (20%; n = 2) and nasal tip (10%; n = 1). Reviewing the culture results, the true culture-positive rate was found to be 50% after cases of contamination were excluded. To avoid permanent sequelae, all physicians should be aware of possible secondary infections when treating filler-induced skin necrosis.

Abstract
AIM To identify odontogenesis-promoting compounds and examine the molecular mechanism underlying enhanced odontoblast differentiation and tooth formation. METHODOLOGY Five different nymphaeols, nymphaeol B (NB), isonymphaeol B (INB), nymphaeol A (NA), 3'-geranyl-naringenin (GN) and nymphaeol C (NC) were isolated from the fruit of Macaranga tanarius. The cytotoxic effect of nymphaeols on human DPSCs was observed using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The effect of nymphaeols on odontoblast differentiation was analysed with Alizarin Red S staining and odontoblast marker expression was assessed using real-time polymerase chain reaction and Western blot analysis. The molecular mechanism was investigated with Western blot analysis. In order to examine the effect of INB on dentine formation in the developing tooth germ, INB-soaked beads were placed under the tooth bud explants in the collagen gel; thereafter, the tooth bud explant-bead complexes were implanted into the sub-renal capsules for 3 weeks. Tooth root formation was analysed using micro-computed tomography and histological analysis. Data are presented as mean ± standard error (SEM) values of three independent experiments, and results are compared using a two-tailed Student's t-test. The data were considered to have statistical significance when the P-value was less than 0.05. RESULTS Three of the compounds, NB, INB, and GN, did not exert a cytotoxic effect on human DPSCs. However, INB was most effective in promoting the deposition of calcium minerals in vitro (P < 0.001) and induced the expression of odontogenic marker genes (P < 0.05). Moreover, this compound strongly induced the phosphorylation of mitogen-activated protein (MAP) kinases and protein kinase B (AKT) (P < 0.05). The inhibition of p38 MAP, c-Jun N-terminal kinase (JNK), and AKT substantially suppressed the INB-induced odontoblast differentiation (P < 0.001). In addition, isonymphaeol B significantly induced the formation of dentine and elongation of the tooth root in vivo (P < 0.05). CONCLUSIONS Prenylflavonoids, including INB, exerted stimulatory effects on odontoblast differentiation and tooth root and dentine formation via the MAP kinase and AKT signalling pathways. These results suggest that nymphaeols could stimulate the repair processes for dentine defects or injuries.

Abstract
Malignant tumours arising from the sublingual glands are very rare, and the extent and frequency of local invasion or regional spread in malignant sublingual gland tumour (MSLT) has not been fully studied due to the disease rarity. To provide comprehensive features of local and regional spread of MSLT, we reviewed 20 surgical cases for detailed pathological analyses among 26 cases diagnosed as having primary MSLT. Adenoid cystic carcinoma (ACC) was the most common pathological subtype, followed by mucoepidermoid carcinoma. Disease-free and overall survivals at 5 years were 76.1 % and 77.7 %, respectively. High-grade malignant tumours and grade 2-3 ACC accounted for 41.7 % and 85.7 %. Clinical and pathological extraparenchymal extensions were found in 34.6 % and 80.0 %, respectively. Tumour invasion to the lingual nerve and submandibular gland/ductal system were also detected in 40.0 % and 28.6 %. The incidences of lingual nerve invasion in ACC and ACC ≥4 cm were 30.8 % and 42.9 %. Regional nodal involvement occurred in seven of 26 cases, and all metastatic lymph nodes were found in neck levels Ib and IIa. In summary, a significant portion of MSLT cases consisted of high-grade tumours and grade 2-3 ACC; therefore local invasion into adjacent structures should be cautiously evaluated in cases of MSLT.

Abstract
AIM To examine the type of vesicular glutamate transporter (VGLUT)-immunopositive (+) axons that coexpress neuropeptides in the rat and human dental pulp, which may help understand peripheral mechanism of pulpal inflammatory pain in rats and humans. METHODOLOGY The trigeminal ganglia (TG) and the dental pulp of the maxillary molar teeth from three male Sprague-Dawley rats weighing 300-330 g and dental pulps of three healthy human (male) maxillary premolar teeth from three 16 to 28-year-old patients extracted for orthodontic treatment were used. The type of VGLUT + axons that coexpress substance P (SP)- and/or calcitonin gene-related peptide (CGRP) and parvalbumin in the rat TG and in the axons of the rat and the human dental pulp was examined by double fluorescence immunohistochemistry and quantitative analysis. Results were analyzed using one-way anova and the Kruskal-Wallis test. RESULTS SP and CGRP were expressed in many human VGLUT1 + pulpal axons but not in the rat VGLUT1 + TG neurons and pulpal axons (P < 0.05). SP and CGRP were expressed in a considerable number of human VGLUT2 + pulpal axons and also in many rat TG neurons and pulpal axons. The fraction of VGLUT1 + axons expressing parvalbumin was about three times higher in the rat than in the human dental pulp (P < 0.05). CONCLUSIONS These findings suggest that the types of VGLUT + axons, which release neuropeptides, may be different between the rat and the human dental pulp, raising a possibility that peripheral mechanism of pulpal inflammatory pain may be different between rats and humans.

Abstract
A recent class of porous materials, viz., metal-organic frameworks (MOFs), finds applications in several areas. In this work, Cu-based MOFs (Cu-benzene-1,3,5-tricarboxylic acid) along with graphene oxide, viz., Cu-MOF/GO, are synthesized and used further for reducing CO2 electrochemically. The reduction was accomplished in various supporting electrolytes, viz., KHCO3/H2O, tetrabutylammonium bromide (TBAB)/dimethylformamide (DMF), KBr/CH3OH, CH3COOK/CH3OH, TBAB/CH3OH, and tetrabutylammonium perchlorate (TBAP)/CH3OH to know their effect on product formation. The electrode fabricated with the synthesized material was used for testing the electroreduction of CO2 at various polarization potentials. The electrochemical reduction of CO2 is carried out via the polarization technique within the experimented potential regime vs saturated calomel electrode (SCE). Ion chromatography was employed for the analysis of the produced products in the electrolyte, and the results showed that HCOOH was the main product formed through reduction. The highest concentrations of HCOOH formed for different electrolytes are 0.1404 mM (-0.1 V), 66.57 mM (-0.6 V), 0.2690 mM (-0.5 V), 0.2390 mM (-0.5 V), 0.7784 mM (-0.4 V), and 0.3050 mM (-0.45 V) in various supporting electrolyte systems, viz., KHCO3/H2O, TBAB/DMF, KBr/CH3OH, CH3COOK/CH3OH, TBAB/CH3OH, and TBAP/CH3OH, respectively. The developed catalyst accomplished a significant efficiency in the conversion and reduction of CO2. A high faradic efficiency of 58% was obtained with 0.1 M TBAB/DMF electrolyte, whereas for Cu-MOF alone, the efficiency was 38%. Thus, the work is carried out using a cost-effective catalyst for the conversion of CO2 to formic acid than using the commercial electrodes. The synergistic effect of GO sheets at 3 wt % concentration and Cu+OH- interaction leads to the formation of formic acid in various electrolytes.

Abstract
Abstract
Objective
Chronic, preventable conditions like diabetes and hypertension previously seen primarily in adults are increasing among young people. Chronic disease-related potentially preventable hospitalizations (PPH) are costly. The study goal was to quantify potentially preventable hospitalizations (PPH) for chronic disease in those aged 5-29 years in one diverse state of the USA.
Methods
With Hawai'i statewide inpatient 2015-2016 data across all payers, we used standard metrics to capture asthma, diabetes, and hypertension PPH. Denominators were obtained by age group, gender, race/ethnicity, and living in O'ahu vs. other Hawaiian Islands from American Community Survey data. A multivariable negative binomial regression model predicted having a PPH adjusting for age group, gender, race/ethnicity, and O'ahu residency.
Results
Six percent (775) of inpatient hospitalizations among young people, representing 455 unique individuals, were PPH for a chronic disease. The types of PPH inpatient hospitalizations include diabetes (436), asthma (261), heart disease (64) and hypertension (14). The number of PPH visits per individual ranged from 1-20 with a mean of 1.7 (SD: 2.28) visits. The total cost of these PPH during this 2-year time period was $16,762,262. Among unique individuals with a chronic disease PPH (N = 455), the mean age was 17.5 (SD: 8.2); 55% were male. In the multivariable model, those who were between 10-14 years (RR:0.47;0.32-0.69) and 15-19 years (RR:0.46;0.31-0.69) were significantly less likely to have a PPH compared to those aged 5-9 years. Other Pacific Islanders were significantly more likely to have a PPH (RR: 3.08; 2.05-4.63) compared to whites.
Conclusions
Many hospitalizations by those aged 5-29 years were PPH. Pacific Islander youth had PPH chronic disease disparities. Chronic disease prevention and management is critical. Solutions may include equitable chronic disease prevention policies and improving access to culturally relevant care.
Key messages
This study reveals important disparities in youth that may lead to future health risks as well as current poor outcomes.
Other Pacific Islanders were at significantly increased risk for PPH for chronic disease compared to other racial/ethnic groups from early childhood to young adulthood.

Abstract
Abstract
Background
Despite a growing prevalence of chronic disease risk factors, such as obesity, among young people in the United States and other countries, little is known about actual disease prevalence in this population. Almost nothing is known about this topic in many racial/ethnic groups that are rapidly growing in the United States, including Native Hawaiians, Other Pacific Islanders, and Filipinos. Yet these understudied groups are at high risk. The study goal was to determine the statewide prevalence of chronic disease in acute care for those aged 5-29 years, including Native Hawaiians, Filipinos, and Pacific Islanders.
Methods
Using Hawai'i statewide inpatient and emergency department (ED) data across all payers from 2015-2016, we considered the presence of at least one of five target chronic conditions (asthma, hypertension, chronic kidney disease, diabetes, stroke) from 13,514 inpatient stays by 9,467 unique individuals and 228,548 ED visits by 127,854 individuals.
Results
Twenty-eight percent of youth who were hospitalized and 12% with an ED visit had at least one chronic condition. In both inpatient and ED settings, race/ethnicity, age group, and payer varied significantly when comparing those with a chronic condition to those without a chronic condition. Notably, those with a chronic condition were disproportionately Native Hawaiian, Filipino, and Pacific Islander; 32.3% percent of those with an inpatient chronic condition and 34.9% of those with an ED chronic condition were Native Hawaiian.
Conclusions
Chronic diseases, including those more often seen in adulthood, are prevalent in young people in acute care settings in the state of Hawai'i with notable disparities. This data can help justify, guide, and support programs urgently needed to address these changing epidemiological trends, which may be of particular interest for Medicaid.
Key messages
We show that chronic conditions are prevalent in young people in acute care settings in the state of Hawai‘i with notable disparities. This can help justify, guide, and support programs to address these troubling epidemiological trends.

Abstract
Abstract
Background
Diastolic blood pressure has a J-curve relation with coronary heart disease and death, but it is debating whether a J-curve association exists in general population. We aimed to assess the relation of blood pressure to mortality, and whether their association is interacted with presence of high coronary artery calcium (CAC).
Methods
The KOICA registry is a retrospective, multicenter observational study designed to investigate the effectiveness and prognostic value of CAC score for primary prevention of cardiovascular disease in asymptomatic Korean adults. The association between CAC score and blood pressure was assessed. Patients were divided into 2 groups according to the baseline CACS (> 300 and ≤ 300), and all-cause mortality was assessed.
Results
The study population composed 48903 subjects with a mean age of 54 ± 9. There were 425 (0.9%) deaths during follow-up. At baseline, SBP (systolic blood pressure) more than 110 mmHg and DBP (diastolic blood pressure) more than 80 mmHg was associated with increased risk for CACS > 300. In patients with baseline CACS ≤ 300, all-cause mortality was increased in patients with SBP of 110-119 mmHg (HR 1.47, p = 0.023), 130-139 mmHg (HR 1.72, p = 0.002) and ≥ 140 mmHg (HR 1.47, p = 0.042) compared to SBP of 120-129 mmHg, whereas DBP did not predict all-cause mortality. In contrast, SBP was not associated to all-cause mortality in patients with CACS > 300, whereas DBP < 60 mmHg (HR 3.53, p =0.018) and 70-79 mmHg (HR 2.21, p = 0.042) was associated with increased risk for all-cause mortality compared to DBP of 80-89 mmHg.
Conclusion
Low DBP was associated with increased risk for all-cause mortality in subjects with high CAC score, suggesting high-risk for coronary artery disease. However, this J-curve relation was not shown in the population with low CAC score.

Abstract
Abstract
Background
Various bleeding risk scores have been proposed to assess the risk of bleeding in atrial fibrillation (AF) patients undergoing anticoagulation. PRECISE DAPT score has been developed to assess the out-of hospital bleeding risk in patients receiving dual antiplatelet therapy (DAPT). Our objective was to compare the predictive performance between the HAS-BLED (Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile International Normalized Ratio, Elderly, Drugs/Alcohol), ATRIA (Anticoagulation and Risk Factors in Atrial Fibrillation), and PRECISE-DAPT (Predicting Bleeding Complication in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet therapy) score in AF patients using antiplatelet agents or anticoagulants
Methods
We recruited 1,114 consecutive AF patients (51% male; median age, 71 years) receiving antiplatelet agents or oral anticoagulants from January 2014 through December 2018. Major bleeding was defined as according to the Bleeding Academic Research Consortium (BARC) criteria (type 3 or 5: hemodynamic instability, need for transfusion, drop in hemoglobin ≥3 g, and intracranial, intraocular or fatal bleeding). The performance of risk scores were assessed by C-statistic.
Results
Bleeding events occurred in 135 patients (12.1%) during 30 days, and 72 patients (6.5%) from 30 days till 1-year follow-up. Based on the C-statistic, PRECISE-DAPT score (AUC: 0.72, 95% CI: 0.69–0.75) had a good performance, significantly better than HAS-BLED (AUC: 0.64, 95% CI: 0.61–0.67) (p=0.008) or ATRIA scores (AUC: 0.57, 95% CI: 0.54–0.60) (p<0.001) for 30-days bleeding prediction. Also, PRECISE-DAPT score had a good C-statistic (AUC: 0.72, 95% CI: 0.69–0.75) for 1-year bleeding events compared with HAS-BLED (AUC: 0.64, 95% CI: 0.60–0.67) (p=0.02) or ATRIA (AUC: 0.61, 95% CI: 0.58–0.65) (p=0.01).
ROC curve for bleeding
Conclusions
The PRECISE-DAPT score has been used for assessing bleeding events during DAPT. Also, the PRECISE-DAPT score predicted bleedings better than HAS-BLED or ATRIA scores in AF patients. So, the PRECISE-DAPT score may be considered as bleeding risk score during DAPT or oral anticoagulation in clinical practice.

Abstract
Abstract
Background
Although older age is one of the most important risk factor for stroke in atrial fibrillation (AF), it is unclear whether oral anticoagulants are beneficial for AF patients with intermediate CHA2DS2-VASc score (1 for male or 2 for female) according to age threshold. We sought to investigate the effect of age-dependent antithrombotic therapy for ischemic stroke in Korean intermediate risk AF patients.
Methods
We enrolled 29,592 patients (males with CHA2DS2-VASc score of 1 and females with CHA2DS2-VASc score of 2) using the Korean National Health Insurance Service database. The clinical endpoint was the occurrence of ischemic stroke. The propensity score matching method was used to balance covariates across treated and untreated patients.
Results
Treated male AF patients were 6,570 (67.1%) with age <55 years, 7,115 (70.9%) with 55–64 years and 6,470 (68.3%) with 65–74 years in each age risk criterion. Also, treated female AF patients were 3,156 (71.3%) with age <55 years, 2,838 (71.0%) with 55–64 years and 3,440 (72.6%) with 65–74 years in each age risk criterion. Among male and female patients (age <55 years and 55–64 years) with 1 risk factor, an annual ischemic stroke rate was not significantly different between treated and untreated patients at full follow-up. However, treated AF patients who are in age 65–74 year without other risk factor had a much lower annual risk of ischemic stroke [(1.05%/year (male) and 1.04%/year (female)] compared with untreated patients [(1.77%/year (male) (p<0.026) and 1.86%/year (female) (p<0.041).
Conclusions
Age is an important predictor in determining the risk of ischemic stroke in AF patients with intermediate CHA2DS2-VASc scores (1 for male or 2 for female). We suggest that the benefit of anti-thrombotic therapy for intermediate risk AF patients depends on age threshold.

Abstract
Abstract
Background
Sex category (Sc, ie, female sex) confers 1 point on CHA2DS2-VASc score. So, no woman with atrial fibrillation (AF) can have a CHA2DS2-VASc score of 0. This study aimed to compare CHA2DS2-VA (excluding female sex) and CHA2DS2-VASc score in Korean AF patients.
Methods
Using the Korean National Health Insurance Service database, we analyzed the risk of ischemic stroke in non-valvular AF patients between 2013 and 2017. The predictive value of the CHA2DS2-VA and CHA2DS2-VASc scores for ischemic stroke was evaluated by c-statistic difference and net reclassification improvement (NRI). The propensity score matching method was used to balance covariates across male and female AF patients.
Results
A total of 182,133 patients with AF (49.2% women) were included to this study. The adjusted incidence rate (IR) of ischemic stroke was not significantly different between males and females (0.89%/y and 0.90%/y, respectively, p=0.411) in low-risk patients without risk factor. Also, no sex difference was found in high-risk patients with above 2 risk factors for ischemic stroke (4.46%/y for male and 4.49%/y for male, p=0.498). In c-statistic analysis for ischemic stroke, there was no significant difference between the CHA2DS2-VA and CHA2DS2-VASc scores (AUC 0.662 vs. 0.664, z=1.572, p=0.116). When compared with CHA2DS2-VASc score, CHA2DS2-VA score was not significantly inferior in net reclassification improvement (NRI 0.031, 95% CI 0.002–0.037, p=0.118) for ischemic stroke.
C-statistics
Conclusions
In Korean AF patients, the CHA2DS2-VA score excluding female sex is a useful risk scoring system for ischemic stroke.

Abstract
Abstract
Background
Chest pain is a major symptom of coronary artery disease (CAD), which can lead to acute coronary syndrome and sudden cardiac death. Accurate diagnosis of CAD in patients who experience chest pain is crucial to provide appropriate treatment and optimize clinical outcomes.
Objective
This study was to develop a machine learning model which can predict and diagnose CAD in patients complaining of chest pain based on a large real-world prospective registry database and computing power.
Method
A total of 10,177 subjects with typical or atypical chest pain who underwent a coronary angiography at the cardiovascular center of our University Hospital, South Korea between November 2004 and May 2014 were evaluated in this study. The generation of the diagnostic prediction model for CAD used the classification application by technical support of MATLAB R2017a. The performance evaluation of the learning model generated by machine learning was evaluated by the area under the curve (AUC) of the receiver-operating characteristic (ROC) analysis.
Results
The diagnostic prediction model of CAD had been generated according to the user's accessibility such as the general public or clinician (Model 1–4). The performance of the models has ranged from 0.78 to 0.96 by the AUC of ROC analysis. The prediction accuracy of the models ranged from 70.4% to 88.9%. The performance of the diagnostic prediction model of CAD by machine learning improved as the input information increased.
Figure 1. Study Flow Chart
Conclusion
A diagnostic prediction model of CAD using the machine learning method and the registry database was developed. Further studies are needed to verify our results.

Abstract
Abstract
Aims
The clinical meaning of a trans-stent pressure gradient after DES implantation has not been estimated adequately. We evaluated the usefulness of a fractional flow reserve (FFR) gradient across the stent (ΔFFRstent) for long-term clinical outcomes after percutaneous coronary intervention (PCI) with a drug-eluting stent (DES).
Methods and results
FFR pull-back and intravascular ultrasound (IVUS) were performed after successful PCI in 135 left anterior descending artery lesions. ΔFFRstent was defined as the FFR gradient across the stent. The ΔFFRstent/length was defined as the ΔFFRstent value divided by the total stent length multiplied by 10 [= (ΔFFRstent ÷ stent length) x 10]. Major adverse cardiac events (MACEs) were the composite of all-cause death, target vessel related myocardial infarction, and target lesion revascularisation. Despite successful PCI without significant complications on IVUS, ΔFFRstent >0 was observed in 98.5% of cases. ΔFFRstent ≥0.04 and ΔFFRstent/length ≥0.009 predicted suboptimal stenting defined as final minimal stent area <5.5 mm2. During 2183±898 days, the MACE-free survival rate was significantly lower in patients with ΔFFRstent ≥0.04 and ΔFFRstent/length ≥0.009 compared to those with lower values (69.6 vs. 93.4%, log-rank p=0.031; 72.1 vs. 97.7%, log-rank p=0.003, respectively). ΔFFRstent/length ≥0.009 (hazard ratio 10.1, p=0.032) was an independent predictor of MACE.
Trans-stent FFR and MACE
Conclusion
A trans-stent FFR gradient was frequently observed in DES-treated patients despite successful PCI results. ΔFFRstent and ΔFFRstent/length are useful indicators for optimising a DES and are related to long-term outcomes.

Abstract
Abstract
Background
Although advances in medical technology and health care have led to increased life expectancy, the prevalence of chronic diseases such as hypertension, diabetes, stroke and cardiovascular events has increased.
Purpose
This study evaluated the prevalence of hypertension, treatment, and the impact of hypertension on cardiovascular disease (CVD) and stroke risk in Koreans.
Methods
The Korean National Health and Nutritional Examination Survey (KNHANES) database, which is a stratified random sampling to assess the health and nutritional status of Koreans (https://knhanes.cdc.go.kr), was analyzed for this study. The subjects of the survey were sampled to represent the entire population of the Republic of Korea. The endpoints of the study are the risk of CVD and stroke due to the prevalence of hypertension. We also examined the relationship between the control of hypertension and the risk of CVD and stroke.
Results
The prevalence of hypertension has increased rapidly as with longer life expectancy of the population. As the duration of hypertension increases, CVD and stroke risks are increased. Achieving a target goal blood pressure below 140/90 mmHg can reduce the risk of all CVD and stroke by nearly half.
Korea-HTN
Conclusion
The risk of CVD and stroke in hypertensive patients can be significantly reduced by achieving optimal blood pressure control.

Abstract
BACKGROUND The selection of reference genes is essential for quantifying gene expression. Theoretically they should be expressed stably and not regulated by experimental or pathological conditions. However, identification and validation of reference genes for human cancer research are still being regarded as a critical point, because cancerous tissues often represent genetic instability and heterogeneity. Recent pan-cancer studies have demonstrated the importance of the appropriate selection of reference genes for use as internal controls for the normalization of gene expression; however, no stably expressed, consensus reference genes valid for a range of different human cancers have yet been identified. RESULTS In the present study, we used large-scale cancer gene expression datasets from The Cancer Genome Atlas (TCGA) database, which contains 10,028 (9,364 cancerous and 664 normal) samples from 32 different cancer types, to confirm that the expression of the most commonly used reference genes is not consistent across a range of cancer types. Furthermore, we identified 38 novel candidate reference genes for the normalization of gene expression, independent of cancer type. These genes were found to be highly expressed and highly connected to relevant gene networks, and to be enriched in transcription-translation regulation processes. The expression stability of the newly identified reference genes across 29 cancerous and matched normal tissues were validated via quantitative reverse transcription PCR (RT-qPCR). CONCLUSIONS We reveal that most commonly used reference genes in current cancer studies cannot be appropriate to serve as representative control genes for quantifying cancer-related gene expression levels, and propose in this study three potential reference genes (HNRNPL, PCBP1, and RER1) to be the most stably expressed across various cancerous and normal human tissues.

Abstract
UNLABELLED We evaluated osteoporosis treatment and DEXA utilization rates of patients who were admitted for hip fracture in a single healthcare system in Hawaii from 2015 to 2016. We found that osteoporosis treatment and DEXA utilization rates were low, highlighting a critical gap in osteoporosis care after admission for hip fracture. INTRODUCTION The objective of this study was to evaluate osteoporosis care after an admission for hip fracture at three community hospitals within a single healthcare system in Hawaii. METHODS A retrospective chart review was conducted (n = 428) of patients ≥ 50 years and hospitalized for hip fractures between January 1, 2015, and May 31, 2016, at three major hospitals within Hawaii Pacific Health, a large healthcare system in Hawaii. Basic demographics were collected, and medications prescribed were quantified and described within 1 year of hip fracture. Logistic regression was used to evaluate the association between collected variables and the odds of osteoporosis treatment. RESULTS Only 115 (26.9%) patients were prescribed a medication for osteoporosis as a secondary prevention within a year of hospitalization for hip fracture. DEXA scans were performed in 137 (32.0%) patients. Most of the treated patients were prescribed oral bisphosphonates. Treatment facility, female gender, and higher BMI were found to be predictive factors for osteoporosis treatment. CONCLUSION The use of osteoporosis medication for secondary prevention after admission for hip fracture in Hawaii is low. Efforts need to be made to improve treatment rates, especially among males.

Abstract
To identify microbial squalene that has been widely used in various industrial applications, intracellular formation of photosynthetic squalene was investigated using the previously engineered Synechococcus elongatusPCC 7942 strain. Unlike the proposed localization of squalene in the membrane bilayer, small droplets were identified in the cytoplasm of S. elongatusPCC 7942 as squalene using transmission electron microscopy analysis. Determination of the diameters of the squalene droplets with manual examination of 1016 droplets in different squalene-producing strains indicated larger squalene droplets in larger cells. Based on the observation of a sole droplet of squalene in a cyanobacterium, fluorescent Nile red was used for the selective staining of squalene. The fluorescent intensities were correlated with squalene contents determined using gas chromatography-mass spectrometry. Photosynthetic squalene was identified as a small droplet in S. elongatusPCC 7942, and this noninvasive quantitative method could be useful to promote high-throughput strain development for squalene production. SIGNIFICANCE AND IMPACT OF THE STUDY Engineering of Cyanobacteria has focused on sustainable production of squalene by converting CO2 . Before improving the photosynthetic squalene production, we characterized formation of squalene, showing small droplets in the cytoplasm instead of single granule. Based on the finding and the analysis, this study has provided valuable evidences how further metabolic engineering strategies should apply to enhance the production yield.

Abstract
Objective To study the impact of patient education video in improving patient satisfaction in the accident and emergency department (AED). Methods This was a descriptive questionnaire study. A 20-minute patient education video in Cantonese was produced. The video was shown in the waiting hall from 9 am to 5 pm during the weekdays of a week in January 2008. All category 4 (semi-urgent) and category 5 (non-urgent) patients were invited to fill in an evaluation questionnaire after watching the video. The demographics of the patients were collected. There were two parts in the questionnaire. Part 1 contained four questions to test patients' knowledge retention after watching the video. These included questions on pharmacy location, triage system, use of patient identification slip and scope of the AED service. Part 2 contained six evaluation items (based on the 5-point Likert scale) to assess patients' opinion on the education video, understanding of the AED workflow and level of satisfaction after watching. Statistical analysis was performed to compare the knowledge retention scores and the Likert responses between different age and education level subgroups. Results Altogether 177 questionnaires were returned; 72 were excluded due to incomplete answers or absent patient gum label; and 105 completed questionnaires were analysed. Of the latter, 83 (79%) respondents scored 75% or more in the questions on knowledge retention, 79 (75%) respondents agreed that they understood the workflow of the AED better, 63 (60%) respondents thought that the video covered most frequently asked questions, and 69 (66%) respondents agreed that their level of satisfaction had improved after watching the video. There was no statistically significant difference on comparing the knowledge retention scores between different age and education level subgroups. Respondents more than 60 years old stated a better understanding about the location of consultation rooms after watching the video. Conclusion A patient education video is useful in providing information about operation and improving patient satisfaction in the accident and emergency department.

Abstract
Solid pseudopapillary neoplasm (SPN) of the pancreas is considered a low-malignant neoplasm with a good prognosis. However, 5% to 15% of patients with SPNs develop metastatic disease, most commonly in the liver. Metastatic hepatic malignancies that show pseudocystic features are rare. Here we describe the case of a middle-aged female with a cystic liver metastasis from SPN. To the best of our knowledge, SPN with a single cystic liver metastasis has not been described, although these tumours frequently undergo haemorrhagic-cystic degeneration. Thus, in these patients the marked cystic change could be misinterpreted as a benign lesion.

Abstract
BACKGROUND Noninvasive skin-tightening devices have become increasingly popular in response to increasing demand for improvements in skin laxity and tightening with minimal risk and recovery time. OBJECTIVE We evaluated the efficacy and safety of HIFU for skin tightening in the face and body. METHODS A total of 32 Korean subjects enrolled in this prospective clinical trial. The subjects were treated with HIFU to both cheeks, lower abdomen, and thigh. Skin elasticity was measured before and after treatment using a Cutometer (CT575, Courage and Khazaka® , Cologne, Germany). Three blinded, experienced dermatologists evaluated paired pre- and post-treatment (week 4 and 12) photographs according to the Global Aesthetic Improvement Scale (GAIS). Participants also completed self-assessments using GAIS. Subjects rated their pain on a numeric rating scale (NRS) immediately, 7 days, 4 weeks, and 12 weeks after treatment. RESULTS Skin elasticity measured via a Cutometer was significantly improved 12 weeks after treatment at all treated sites (P<.05). Both IGAIS and SGAIS showed significant improvements 12 weeks after treatment. Immediately after treatment the mean NRS score was 3.00±1.586, but no pain was reported at 4 and 12 weeks post-treatment. No serious adverse effects were observed during the follow-up period. CONCLUSION HIFU safely and effectively improves skin elasticity and clinical contouring of the face and body.

Abstract
Radiofrequency ablation (RFA) has evolved to become the treatment of choice for non-resectable recurrent colorectal liver metastasis. It is however, not without complications. Portal vein thrombosis following RFA is rare but can be fatal to the outcome of the patient. Here, we present a case of a 66-year-old man who developed portal vein thrombosis following RFA. CT scan revealed a left portal vein thrombosis. This case report highlights the challenges and multimodal treatment of portal vein thrombosis following Radiofrequency ablation (RFA) in a cirrhotic patient.

Abstract
A Ho:YAG ceramic microchip laser pumped by a Tm fiber laser at 1910 nm is passively Q-switched by single- and multi-layer graphene, single-walled carbon nanotubes (SWCNTs), and Cr2+:ZnSe saturable absorbers (SAs). Employing SWCNTs, this laser generated an average power of 810 mW at 2090 nm with a slope efficiency of 68% and continuous wave to Q-switching conversion efficiency of 70%. The shortest pulse duration was 85 ns at a repetition rate of 165 kHz, and the pulse energy reached 4.9 μJ. The laser performance and pulse stability were superior compared to graphene SAs even for a different number of graphene layers (n=1 to 4). A model for the description of the Ho:YAG laser Q-switched by carbon nanostructures is presented. This modeling allowed us to estimate the saturation intensity for multi-layered graphene and SWCNT SAs to be 1.2±0.2 and 7±1 MW/cm2, respectively. When using Cr2+:ZnSe, the Ho:YAG microchip laser generated 11 ns/25 μJ pulses at a repetition rate of 14.8 kHz.

Abstract
Heterotopic bone formation is a very rare event in the gastrointestinal tract including in the appendix. Here we report three cases of heterotopic ossification in appendiceal mucinous neoplasms, one occurring in an appendiceal mucinous cystadenoma, another in a low-grade appendiceal mucinous neoplasm, and the third occurring in an appendiceal mucinous adenocarcinoma. The clinicopathologic characteristics of these three present cases and two previously reported cases are discussed in detail. The mechanism of heterotopic ossification in appendiceal mucinous neoplasm is still unclear, but mucin extravasation and subsequent calcification may be predisposing events.

Abstract
Bone tissue engineering may provide an alternative to autograft, however scaffold optimisation is required to maximize bone ingrowth. In designing scaffolds, pore architecture is important and there is evidence that cells prefer a degree of non-uniformity. The aim of this study was to compare scaffolds derived from a natural porous marine sponge (Spongia agaricina) with unique architecture to those derived from a synthetic polyurethane foam. Hydroxyapatite scaffolds of 1 cm(3) were prepared via ceramic infiltration of a marine sponge and a polyurethane (PU) foam. Human foetal osteoblasts (hFOB) were seeded at 1 × 10(5) cells/scaffold for up to 14 days. Cytotoxicity, cell number, morphology and differentiation were investigated. PU-derived scaffolds had 84-91% porosity and 99.99% pore interconnectivity. In comparison marine sponge-derived scaffolds had 56-61% porosity and 99.9% pore interconnectivity. hFOB studies showed that a greater number of cells were found on marine sponge-derived scaffolds at than on the PU scaffold but there was no significant difference in cell differentiation. X-ray diffraction and inductively coupled plasma mass spectrometry showed that Si ions were released from the marine-derived scaffold. In summary, three dimensional porous constructs have been manufactured that support cell attachment, proliferation and differentiation but significantly more cells were seen on marine-derived scaffolds. This could be due both to the chemistry and pore architecture of the scaffolds with an additional biological stimulus from presence of Si ions. Further in vivo tests in orthotopic models are required but this marine-derived scaffold shows promise for applications in bone tissue engineering.

Abstract
Malignant mesonephric tumor (MMT) is a relatively uncommon malignancy of the female genital tract. The diagnosis of metastatic MMT is difficult because cytological, pathological, immunohistochemical characteristics of MMT are under-recognized. The authors present a 55-year-old female with metastatic pulmonary nodules. The bronchial washing cytology revealed three dimensional clusters of bland epithelial cells with slight nuclear grooves. A corresponding lung histology had ductal or tubular clusters of epithelial cells with intraglandular eosinophilic materials. These epithelial cells were positive for immunohistochemical stain of CD10, suggesting metastasis from MMT. The cervical smear showed clusters of bland, gland-forming epithelial cells with intraglandular eosinophilic materials. On histologic examination, mesonephric adenocarcinoma with papillary and solid proliferation was identified in the uterine cervix. A review of the literature for 72 cases of MMT is also included. Clinical and cytopathological features of MMT are herein made available.

Abstract
BACKGROUND/PURPOSE The clinical skin tightening benefits of high intensity focused ultrasound (HIFU) have been established, but its mechanism of action in pigmented skin disorders remains unknown. We macroscopically and histopathologically investigated dermatological changes after HIFU at different exposure doses in a UVB-induced guinea pig model of hyperpigmentation. METHODS We applied HIFU irradiation at 0.1 and 0.2 J/cm(2) to UVB-induced spotty hyperpigmentation in guinea pig skin. The therapeutic effects of HIFU were judged based on gross appearance using photography, dermoscopy, and chromametry during a period of 3 weeks after HIFU irradiation. Histological assessments were performed using Fontana-Masson staining 1 day before and 3 weeks after HIFU irradiation. RESULTS Macroscopically, UVB-induced hyperpigmentation was significantly reduced 2 weeks after HIFU with 0.2 J/cm(2) , and 3 weeks after HIFU with 0.1 J/cm(2) . Histopathologically, the heavy deposition of melanin in the epidermis induced by UVB exposure was reduced 3 weeks after HIFU irradiation. CONCLUSION We confirmed that HIFU has a positive effect on UVB-induced hyperpigmentation as well as mechanical destructive activity. We suggest that HIFU may be useful as an alternative modality for human patients suffering from skin pigmentary conditions.

Abstract
We have previously shown that 2-(3-(benzo[d]thiazol-2-yl)ureido)acetate (KHG21834) attenuates amyloid beta(Aβ)25-35-induced apoptotic death and shows anti-inflammatory activity against Aβ25-35-induced microglial activation. However, antioxidative effects of KHG21834 against Aβ-induced oxidative stress have not yet been reported. In the present study, we investigated the antioxidative function of KHG21834 in primary cultured cortical neurons, to expand the potential therapeutic efficacy of KHG21834. Pretreatment with KHG21834 protected against Aβ-induced neuronal cell death and mitochondrial damage, and significantly restored GSH levels and the activities of catalase, superoxide dismutase, and glutathione peroxidase, and also suppressed the production of reactive oxygen species and protein oxidation. These results imply that KHG21834 may play a role in cellular defense mechanisms against Aβ-induced oxidative stress in cultured cortical neurons. Furthermore, KHG21834 significantly attenuated the effects of Aβ treatment on levels of NF-κB, β-catenin, and GSK-3β proteins in cortical neurons. Taken together, our results suggest that the antioxidant effects of KHG21834 may result at least in part from its ability to regulate the NF-κB, β-catenin, and GSK-3β signaling pathways. To our knowledge, this is the first report showing that KHG21834 significantly attenuates Aβ25-35-induced oxidative stress in primary cortical neurons, and provides novel insights into KHG21834 as a possible therapeutic agent for the treatment of Aβ-mediated neurotoxicity involving oxidative stress.

Abstract
BACKGROUND The transplantation of isolated islets is thought to be an attractive approach for curative treatment of diabetes mellitus. Panax ginseng has been used in oriental countries for its pharmacologic effects, such as antidiabetic and antiinflammatory activities. 20(S)-ginsenoside Rg3 (Rg3), an active ingredient of ginseng saponins, has been reported to enhance insulin secretion-stimulating and antiapoptotic activities in pancreatic beta cells. We performed this study to examine the hypothesis that preoperative Rg3 administration can enhance islet cell function and antiapoptosis before islet transplantation. METHODS Balb/c mice were randomly divided into 2 groups according to the administration of Rg3 after islet isolation. Mouse islets were cultured in medium supplemented with or without Rg3. In vitro, islet viability and function were assessed. After treatment of islets with a cytokine cocktail (tumor necrosis factor α, interferon-γ, and interleukin-1β), cell viability, function, and apoptosis were assessed. RESULTS Cell viability was similar between the 2 groups. Islets cultured in medium supplemented with Rg3 showed 2.3-fold higher glucose-induced insulin secretion than islets cultured in medium without Rg3. After treatment with a cytokine cocktail, glucose-induced insulin release, total insulin content of islets, and apoptosis were significantly improved in Rg3-treated islets compared with cytokine-treated islets. Cytokine-treated islets produced significantly higher levels of nitric oxide (NO) than islets treated with Rg3. CONCLUSIONS These results suggest that preoperative Rg3 administration enhanced islet function before islet transplantation and attenuated both cytokine-induced damage associated with NO production and apoptosis. Rg3 administration might be a prospective management to enhanced islet function and ameliorate early inflammation after transplantation.

Abstract
BACKGROUND Renal transplantation is the best treatment for patients with end-stage renal disease. Although there is significantly increased risk of malignancy after renal transplantation, carcinoma of the native kidney is very rare, and moreover, the risk of endocrinologic malignancy after renal transplantation is lower than in the general population and adrenal cortical carcinoma extremely rare. We report a case of incidental renal cell carcinoma originating from a native kidney after en-bloc resection for adrenal carcinoma in a kidney transplant recipient. CASE REPORT A 57 year-old male patient had undergone living-donor kidney transplantation for chronic renal failure from hypertension 15 years earlier and had a right adrenal tumor diagnosed on surveillance abdomen-pelvis computerized tomography. Based on 24-hour catecholamine laboratory findings, nonfunctioning tumor was suspected. The planned en-bloc resection of right adrenal gland and right native kidney combining the perirenal tissue and Gerota fascia was performed, because the tumor was suspicious for malignancy and could possibly invade the perirenal tissue or right kidney. On the final pathology, combined adrenal cortical carcinoma and incidental renal cell carcinoma was confirmed. Renal cell carcinoma was papillary, type I, and stage T1N0M0. Adrenal cortical carcinoma was 7.6 × 6.5 cm in size, had marked nuclear atypia, and was grade IV/IV. Mitotic counts were >10 per high-power field, but it had no capsular invasion or vascular invasion, and free resection margin was confirmed. In the preoperative period, he had taken immunosuppressants FK506 and mycophenolate sodium, but after combined carcinomas were confirmed, the regimen of combination of immunosuppressants was changed to sirolimus with low-dose FK506 and half-dose mycophenolate sodium.
