    Abstract: As a result of restrictions on animal experimentation, improved skin equivalents (SEs) are needed as alternative test models. This work investigated the effects of avian collagen on the construction of SEs, and to the best of our knowledge is the first study to do so. Hematoxylin and eosin and immunohistochemical staining were used to analyze the SEs. In models containing avian collagen as a dermal equivalent (DE) ingredient, fibroblast proliferation increased by about 60% relative to the control model. Immunohistochemical staining showed that the expression of proliferating cell nuclear antigen (PCNA) and p63 increased in the avian collagen models, while the expression of involucrin, integrin α 〈 sub 〉 6 〈 /sub 〉 , and integrin β 〈 sub 〉 1 〈 /sub 〉 remained unchanged. Next, DEs were cryopreserved to allow the easier creation of SEs. Keratinocytes were seeded on thawed DEs, and SEs were constructed. Avian collagen increased the viability of DEs relative to the control. Furthermore, avian collagen increased the expression of PCNA and p63 in keratinocytes on thawed DEs. The results indicate that DEs containing avian collagen can be thawed as needed after cryopreservation. Avian collagen can improve the construction of SEs and be used as part of a dermal kit for SE construction.

    Abstract: 〈 b 〉 〈 i 〉 Background and Aims: 〈 /i 〉 〈 /b 〉 The purpose of our study was to examine the histopathologic characteristics of hepatocellular carcinoma (HCC) with irregular rim-like arterial phase enhancement (IRE), which has been reported to be associated with more aggressive tumor behavior. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 We investigated 84 pathologically confirmed HCCs in 84 patients who underwent curative hepatic resection after gadoxetate-enhanced magnetic resonance imaging between January 2008 and February 2013. Two abdominal radiologists independently reviewed these images and classified HCCs into two categories: HCC showing IRE (IRE-HCC) and HCC showing hypoenhancement or diffuse arterial enhancement (non-IRE-HCC). Twenty-two HCCs were classified as IRE-HCCs, and 51 were classified as non-IRE-HCCs concordantly by both reviewers. The remaining 11 HCCs, on whose radiologic classifications the reviewers disagreed, were classified as HCCs with intermediate enhancement patterns. The HCC clinicopathologic characteristics and patient outcomes were then compared. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 IRE-HCCs showed more frequent microvascular invasion (91 vs. 35%), lower microvascular density (246.5 vs. 426.5/mm 〈 sup 〉 2 〈 /sup 〉 ), higher proportions of sinusoid-like microvascular pattern (55 vs. 0%) and macrotrabecular pattern (45 vs. 0%), and larger areas of tumor necrosis (15 vs. 0%) and fibrous stroma (8.3 vs. 2.1%) than non-IRE-HCCs. IRE-HCCs also expressed higher levels of immunomarkers of hypoxia (carbonic anhydrase IX, 64 vs. 8%) and stemness (EpCAM, 50 vs. 20%). 〈 i 〉 p 〈 /i 〉 values were & #x3c; 0.001 for all comparisons except for EpCAM ( 〈 i 〉 p 〈 /i 〉 = 0.026). HCCs with intermediate enhancement patterns showed mixed/intermediate pathologic features from both IRE- and non-IRE-HCCs. IRE-HCC patients showed poorer 5-year disease-free survival after curative resection than non-IRE-HCC patients ( 〈 i 〉 p 〈 /i 〉 = 0.005). 〈 b 〉 〈 i 〉 Conclusions: 〈 /i 〉 〈 /b 〉 IRE-HCCs demonstrate aggressive histopathologic features, including more hypoxic and fibrotic tumor microenvironments and increased stemness, compared to non-IRE-HCCs. IRE might therefore serve as a noninvasive imaging biomarker for aggressive HCC.

    Abstract: 〈 b 〉 〈 i 〉 Background/Aims: 〈 /i 〉 〈 /b 〉 This prospective study was conducted to investigate the feasibility of an early discontinuation of thyroid hormone treatment in very-low-birth-weight (VLBW) infants with congenital hypothyroidism (CH). 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 We enrolled VLBW infants between January 2011 and December 2012. The infants were divided into the hypothyroid and normal thyroid function groups according to the results of a thyroid function test. We performed an early off-therapy trial at 24 months of age. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Of the 182 VLBW infants enrolled, 15 were lost to follow-up and 167 were finally enrolled. In total, 24 infants (14.4%) were assigned to the hypothyroid function group and were treated with thyroid hormone. Younger gestational age and a lower birth weight were associated with hypothyroid function. In the hypothyroid function group, hypothyroidism (HT) and hyperthyrotropinemia (HTT) were observed in 13 and 11 infants, respectively. There were no differences in the clinical characteristics between the HT and HTT groups. Overall, 24 infants discontinued thyroxine medication at 24 months of age after normal results had been confirmed by radiologic work-ups, including thyroid ultrasonography and technetium-99m scans. All infants were successfully weaned off thyroxine and maintained euthyroid function. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 Early discontinuation of thyroid hormone replacement therapy is possible in the majority of VLBW infants with CH.

    Abstract: Monoclonal gammopathy with undetermined significance (MGUS) carries a risk of progression to multiple myeloma, and progression is usually diagnosed with changes in M-protein or bone marrow biopsy. We report a case of 62-year-old female patient showing MGUS progression to multiple myeloma without significant changes in M-protein but diagnosed by kidney biopsy. During the follow-ups, azotemia and tubular proteinuria were aggravated without elevation of M-protein. Kidney biopsy showed intratubular and glomerular inclusions associated with plasma cell dysplasia. The progression of MGUS to multiple myeloma was diagnosed by this kidney biopsy. The patient's renal function and tubular proteinuria were markedly improved after chemotherapy.

    Abstract: Although statins are established therapy for the secondary prevention of ischemic stroke, factors associated with adherence to statin treatment following ischemic stroke are not well known. To address this, we assessed the 6-month statin adherence using 8-item Morisky Medication Adherence Scale-8 in patients with acute ischemic stroke. Of 991 patients, 65.6% were adherent to statin at 6-month after discharge. Multiple logistic regression analysis showed that patients’ awareness of hyperlipidemia (OR 1.62; 95% CI 1.07–2.43), large artery stroke subtype (versus non-large artery stroke, OR 1.79; 95% CI 1.19–2.68), and alcohol drinking habits (OR 1.64; 95% CI 1.06–2.53) were positively associated, while high statin dose (versus low dose, OR 0.6; 95% CI 0.40–0.90) and higher daily number of medication pills (OR 0.93; 95% CI 0.88–0.97) were found to have a negative association with self-reported good adherence to statin medication after acute ischemic stroke. However, stroke severity and diagnosis of hyperlipidemia were not associated with adherence. These results suggest that educational and motivational interventions may enhance statin adherence because modifiable factors were associated with statin adherence.

    Abstract: Influenza A virus (IAV) poses a constant worldwide threat to human health. Although conventional vaccines are available, their protective efficacy is type or strain specific, and their production is time-consuming. For the control of an influenza pandemic in particular, agents that are immediately effective against a wide range of virus variants should be developed. Although pretreatment of various Toll-like receptor (TLR) ligands have already been reported to be effective in the defense against subsequent IAV infection, the efficacy was limited to specific subtypes, and safety concerns were also raised. In this study, we investigated the protective effect of an attenuated bacterial outer membrane vesicle ­harboring modified lipid A moiety of lipopolysaccharide (fmOMV) against IAV infection and the underlying mechanisms. Administration of fmOMV conferred significant protection against a lethal dose of pandemic H1N1, PR8, H5N2, and highly pathogenic H5N1 viruses; this broad antiviral activity was dependent on macrophages but independent of neutrophils. fmOMV induced recruitment and activation of macrophages and elicited type I IFNs. Intriguingly, fmOMV showed a more significant protective effect than other TLR ligands tested in previous reports, without exhibiting any adverse effect. These results show the potential of fmOMV as a prophylactic agent for the defense against influenza virus infection.

    Abstract: Mucosal-associated invariant T (MAIT) cells rapidly produce proinflammatory cytokines in an innate-like manner and play an important role in controlling the host immune response. This study examined the function of MAIT cells in trauma patients. The expression of cytokines in peripheral blood MAIT cells was measured by flow cytometry. MAIT cells in trauma patients displayed impaired tumor necrosis factor (TNF)-α production, together with elevated CD69 expression. The expression of CD69 was negatively correlated with MAIT cell frequency. These patients had higher plasma levels of interleukin (IL)-12 and IL-18. In particular, CD69 expression of MAIT cells was increased by stimulation with IL-18 in synergy with other proinflammatory cytokines or plasma of trauma patients. The production of TNF-α by MAIT cells was characterized by an initial burst and rapid decline, in contrast to delayed and sustained production of interferon (IFN)-γ. Activated MAIT cells showed a functional defect in the production of TNF-α upon restimulation. This study demonstrates that circulating MAIT cells are activated and functionally impaired in TNF-α production in patients with trauma. The activation and dysfunction of MAIT cells was mediated by proinflammatory cytokines. These findings provide important information underlying the innate immune response of patients with trauma.

    Abstract: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 The clinical features of hepatocellular carcinoma (HCC) differ in patients with and without cirrhosis. 〈 b 〉 〈 i 〉 Objective: 〈 /i 〉 〈 /b 〉 We aimed to investigate the long-term outcomes of noncirrhotic HCC patients after curative resection. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 We retrospectively examined 649 consecutive patients with HCC who underwent curative resection from 1996 to 2012; 387 (59.6%) were cirrhotic and 262 (40.4%) were noncirrhotic. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 The mean age was 54.7 years, and 511 (78.7%) of the study participants were men. The most common cause of HCC was hepatitis B virus ( 〈 i 〉 n 〈 /i 〉 = 419, 64.6%). Noncirrhotic tumors were larger and more advanced than cirrhotic tumors. However, the noncirrhotic group showed better disease-free survival (DFS) and overall survival (OS) after resection than the cirrhotic group (median 64.0 vs. 56.0 months for OS and 48.0 vs. 31.0 months for DFS, 〈 i 〉 p 〈 /i 〉 〈 0.05). The predictors for HCC recurrence were cirrhosis, tumor number, portal vein invasion, and major surgery. 〈 b 〉 〈 i 〉 Conclusions: 〈 /i 〉 〈 /b 〉 Noncirrhotic HCC showed better DFS and OS after resection than cirrhotic HCC, although noncirrhotic HCC presented more aggressively.

    Abstract: 〈 b 〉 〈 i 〉 Background/Aims: 〈 /i 〉 〈 /b 〉 Visfatin is a known adipokine which may improve insulin resistance in obesity and have an anti-diabetic effect via the insulin receptor. We studied the effects of visfatin on diabetic nephropathy in type 2 diabetic mice. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 Diabetic male 〈 i 〉 db/db 〈 /i 〉 mice were treated with intraperitoneal injections of visfatin. Basal parameters were measured in all mice and glucose tolerance test (GTT) and insulin tolerance test (ITT) were performed in diabetic mice. The histopathological and molecular changes were evaluated in diabetic nephropathy. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Visfatin treatment had no effect on body weight, water and food intake, urinary volume, blood glucose, and HbA1c level. However, visfatin improved HOMA-IR, GTT, ITT and decreased plasma insulin and visfatin level, but not adiponectin level. Plasma cholesterol and triglyceride level were also improved by visfatin treatment. Significantly, visfatin decreased albuminuria in diabetic mice. Glomerulosclerotic change and mesangial expansion in the kidneys were significantly reduced. In addition, visfatin inhibited the expression of proinflammatory and profibrotic cytokines such as MCP-1, TGFβ1, type IV collagen, and PAI-1. The enzymes related to lipid metabolism in the kidney, HMG-CoAR was suppressed by visfatin treatment, whereas FXR and ABCA1 were significantly elevated by treatment. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 Visfatin might have a protective effect in diabetic nephropathy without the hypoglycemic effect.

    Abstract: 〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 This study aimed to assess the association between antenatal corticosteroid (ACS) and in-hospital outcomes of preterm singleton appropriate for gestational age (AGA) infants according to the presence of maternal histologic chorioamnionitis (HCA). 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 A retrospective study was performed with singleton AGA neonates of 23 〈 sup 〉 +0 〈 /sup 〉 to 33 〈 sup 〉 +6 〈 /sup 〉 weeks’ gestation born between 2007 and 2014. We compared the clinical outcomes according to the presence of HCA and ACS use. We also divided the ACS group into 2 groups: infants who received ACS 2–7 days before birth (optimal ACS) or not (suboptimal ACS). Multivariate logistic regression with Firth’s penalized likelihood was performed. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 In total, 254 neonates were eligible with 109 neonates with HCA (42.9%). In multivariate analysis adjusting for GA, sex, and cesarean section, ACS use was associated with reduced severe bronchopulmonary dysplasia (BPD) or death and hypotension within 7 postnatal days among the neonates with HCA. However, it was associated with increased patent ductus arteriosus (PDA) treatment. In the optimal ACS group, severe BPD or death (aOR 0.03, 95% CI 0.01–0.42), hypotension (aOR 0.02, 95% CI 0.01–0.26), and inhaled nitric oxide use (aOR 0.06, 95% CI 0.00–0.81) were lower, however, PDA treatment (aOR 8.14, 95% CI 1.20–55.24) and sepsis (aOR 6.85, 95% CI 1.02–46.07) were higher when compared with the no ACS group among HCA+ infants. Among HCA– infants, only PDA treatment was lower in the ACS group. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 In neonates with HCA, ACS treatment was associated with reduced morbidities. However, increased sepsis was associated with optimal ACS use.
