Abstract
Abstract
Background
The effects of prehospital epinephrine administration in combination with the quality of cardiopulmonary resuscitation (CPR) on neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients with non-shockable rhythm remains unclear.
Purpose
This study aimed to elucidate the effects of prehospital epinephrine administration in combination with the quality of CPR on neurologically intact survival in OHCA patients with non-shockable rhythm.
Methods
We analysed 118,732 adult OHCA patients with non-shockable rhythm from the All-Japan OHCA registry between 2011 and 2016 (29,989 emergency medical service [EMS]-witnessed arrests with EMS-initiated CPR [high-quality CPR] and 88,743 bystander-witnessed arrests with bystander-initiated CPR continued by EMS providers [low-quality CPR]). Patients who achieved prehospital return of spontaneous circulation without prehospital epinephrine administration were excluded. The primary outcome measure was 1-month neurologically intact survival (cerebral performance category 1 or 2; CPC 1–2). Time from collapse to prehospital epinephrine administration for patients with prehospital epinephrine administration, or to hospital arrival for patients without prehospital epinephrine administration was calculated and adjusted collectively in multivariate logistic regression analysis for 1-month CPC 1–2.
Results
Multivariate logistic regression analysis revealed that the time from collapse to prehospital epinephrine administration or to hospital arrival was negatively associated with 1-month CPC 1–2 (adjusted odds ratio [OR] 0.95 per 1-minute increment, 95% confidence interval [CI] 0.94–0.96). Compared with bystander-witnessed arrests without prehospital epinephrine administration, EMS-witnessed arrests with or without prehospital epinephrine administration were significantly associated with increased chances of 1-month CPC 1–2 (adjusted OR 2.04, 95% CI 1.50–2.75 and adjusted OR 1.97, 95% CI 1.57–2.48, respectively). Prehospital epinephrine administration was significantly associated with an increased chance of 1-month CPC 1–2 among bystander-witnessed arrests (adjusted OR 1.57, 95% CI 1.24–1.98), but not among EMS-witnessed arrests. EMS-witnessed arrests without prehospital epinephrine administration were significantly associated with an increased chance of 1-month CPC 1–2 compared with bystander-witnessed arrests with prehospital epinephrine administration (adjusted OR 1.26, 95% CI 1.01–1.56).
Conclusions
High-quality CPR is crucial for increasing neurologically intact survival in OHCA patients with non-shockable rhythm. The additional beneficial effects of prehospital epinephrine administration were observed only among OHCA patients with low-quality CPR.

Abstract
Abstract
Background
Data on the effects of witness status and time from an emergency call to initiation of cardiopulmonary resuscitation (CPR) by emergency medical service (EMS) providers on neurological outcome in out-of-hospital cardiac arrest (OHCA) patients with non-shockable rhythm according to the first documented rhythm are limited.
Purpose
We aimed to determine the effects of witness status and time from an emergency call to CPR initiation by EMS providers on neurologically intact survival in OHCA patients according to the type of non-shockable rhythm (pulseless electrical activity [PEA] and asystole).
Methods
We analysed the records of 583,431 adult OHCA patients with non-shockable rhythm (191,905 bystander-witnessed arrest and 391,526 unwitnessed arrest). Data were derived from the prospectively recorded All-Japan OHCA registry between 2011 and 2016. Call to EMS-CPR interval was defined as the time from an emergency call to CPR initiation by EMS providers. The primary outcome was 1-month neurologically intact survival (cerebral performance category 1 or 2; CPC 1–2) and secondary outcome was presence of PEA.
Results
The rates of 1-month CPC 1–2 were 1.21% (2,326/191,905) for bystander-witnessed arrest and 0.24% (959/391,526) for unwitnessed arrest. When divided into 4 groups based on witness status and initial documented rhythm, these rates were 2.42% (1,869/77,190) for bystander-witnessed arrest with PEA (group A), 0.40% (457/114,715) for bystander-witnessed arrest with asystole (group B), 1.51% (679/44,926) for unwitnessed arrest with PEA (group C) and 0.08% (280/346,600) for unwitnessed arrest with asystole (group D). Multivariate logistic regression analysis revealed each 1-min delay of Call to EMS-CPR interval to be significantly associated with decreased chances of 1-month CPC 1–2 for groups A, B and D (adjusted odds ratio [OR]: 0.95, 0.91 and 0.96, respectively; 95% confidence interval [CI]: 0.93–0.96, 0.88–0.94 and 0.93–0.99, respectively). However, for group C, there was no significant relationship between these variables (adjusted OR: 1.00; 95% CI: 0.98–1.02). The proportion of PEA was 40.2% (77,190/191,905) for bystander-witnessed arrest and 11.5% (44,926/391,526) for unwitnessed arrest. Multivariate logistic regression analysis revealed that, as Call to EMS-CPR interval lengthened (per 1-min delay), the number of OHCA patients with PEA decreased for bystander-witnessed arrest (adjusted OR: 0.94; 95% CI: 0.93–0.94) and for unwitnessed arrest (adjusted OR: 0.96; 95% CI: 0.96–0.97).
Conclusions
The 1-month CPC 1–2 rate differed by witness status and initial documented rhythm in OHCA patients with non-shockable rhythm. Shortening of Call to EMS-CPR interval is crucial for improving 1-month CPC 1–2 rate and sustaining PEA, particularly in bystander-witnessed arrest.

Abstract
BACKGROUND/AIM This study aimed to investigate aclarubicin (ACR)-induced oxidative DNA damage and apoptosis. MATERIALS AND METHODS ACR-induced apoptosis was analyzed using HL-60 leukemia cells and HP100 cells, hydrogen peroxide (H2O2)-resistant cells derived from HL-60 cells. ACR-induced DNA damage was analyzed using plasmid DNA. RESULTS HL-60 cells were more sensitive to ACR than HP100 cells. In HP100 cells, DNA ladder formation and caspase-3/7 activity induced by ACR were suppressed or delayed in comparison to those in HL-60 cells. ACR-induced DNA damage occurred in the presence of Cu(II), and scavenger experiments showed that the reactive species causing DNA damage appeared to be generated from H2O2 and Cu(I). Moreover, we detected intracellular Cu(I) induced by ACR in HL-60 cells, using CopperGREEN™, a fluorescent probe for detection of Cu(I) ion specifically. CONCLUSION ACR-induced DNA damage and apoptosis can be accounted for by the involvement of H2O2 and Cu(I).

Abstract
BACKGROUND Palmoplantar pustulosis (PPP) is a distinct, chronic skin disorder characterized by intraepidermal pustules on the palms and soles. It is hypothesized that microorganisms on the skin might induce the symptoms of PPP via inflammatory cell activation. However, the microbiota has not been studied in detail because of the assumption that the pustules in PPP are sterile. AIM To elucidate the role of microorganisms in pathogenesis of PPP. METHODS PCR analysis was performed of microbial DNA fragments in the pustules of patients with PPP. The sequence of the D1/D2 LSU 26s rRNA gene and that of the 16S rRNA gene was used for fungal and bacterial DNA detection, respectively. RESULTS In total, 71 samples were carefully collected from the pustules of patients with PPP. Fungal DNA bands were detected in 68 samples, and fungi including Malassezia spp. were identified in 30 of 71 samples (42.3%). Malassezia restricta was the most frequently encountered fungus (14/71; 19.7%). However, bacterial DNA was not detected by the methods used. Furthermore, identical fungal DNA was not detected in the outer lid of the pustules, suggesting that the fungi detected within the pustule did not derive from contamination via the skin surface. CONCLUSIONS In the present study, we demonstrated for the first time that certain pustules in patients with PPP contain fungal DNA fragments, especially those of Malassezia spp. Our findings provide new insights on the role of skin microbiota in the pathogenesis of PPP.

Abstract
INTRODUCTION Many reports show that denture adhesives improve the retention and stability of dentures. However, few randomized controlled trials have examined the effects of denture adhesives. OBJECTIVE This 10-center randomized controlled trial with parallel groups involving 200 edentulous patients wearing complete dentures aimed to evaluate the effects of short-term use of cream and powder denture adhesives. METHODS Patients were allocated into 2 cream- and powder-type adhesive groups and 1 control group. Intervention groups were treated with the 2 adhesives (1 each), and the control group received saline solution. Adhesive or control was applied to the denture-mucosal surface for 4 d, and data at baseline and after day 4 of intervention (i.e., 8 meals) were obtained. Patient satisfaction was evaluated with a 100-mm visual analog scale. Oral health-related quality of life was measured with the Japanese version of the Oral Health Impact Profile for Edentulous Patients. Perceived chewing ability was evaluated by a questionnaire regarding ease of chewing and swallowing food. Between-group comparisons were performed with Kruskal-Wallis tests with the Mann-Whitney U test adjusted by Bonferroni correction. Within-group comparisons of pre- and postintervention measurements were performed with the Wilcoxon signed-rank test. Intention-to-treat analysis was also performed. RESULTS Between-group comparisons showed no significant differences for general satisfaction or Oral Health Impact Profile for Edentulous Patients. However, significant differences in satisfaction with various denture functions with cream- and powder-type adhesives were seen in pre- and postintervention comparisons (P < 0.05). Significant differences were also observed for perceived chewing ability of hard foods (P < 0.05). CONCLUSION These results suggest that although denture adhesives do not invariably improve denture function, they do affect subjective evaluations and possibly chewing of hard foods. Therefore, the effects of denture adhesive use are insufficient to resolve any fundamental dissatisfaction with dentures ( ClinicalTrials.gov NCT01712802 ). KNOWLEDGE TRANSFER STATEMENT The results of this study suggest that denture adhesives should be applied under certain conditions; however, an appropriate diagnosis is important before application. These practice-based data provide information to establish evidence-based guidelines for applying denture adhesives.

Abstract
BACKGROUND Major depressive disorder (MDD) is a common and often chronic problem. Patients with chronic MDD often have negative impacts on the health of their families. Family psychoeducation is recognized as part of the optimal treatment for patients with psychotic disorder, and has been shown to reduce the rate of relapse in individuals with schizophrenia and to reduce the burden on their caregivers. Thus, we predict that family psychoeducation has the potential to reduce the burden on the caregivers of patients with chronic MDD. In the present study, we aimed to investigate the effects of brief multifamily psychoeducation (BMP) on the mental health status of family members of patients with chronic MDD. METHODS We conducted a clinical trial consisting of 49 chronic MDD patients and their families. Each family was randomly assigned to either the BMP intervention group or the control group. The intervention group received four BMP sessions, once every two weeks for eight weeks. The control group received one counseling session administered by a nurse. All patients received standard treatment administered by physicians. The primary outcome measurement was the Kessler Screening Scale for Psychological Distress (K6) score of family members at 16- weeks after the first BMP session. Secondary outcomes were depressive symptoms of both family members and patients at multiple time points, as well as family functioning as evaluated by the patients. Intention-to-treat analyses were conducted. RESULTS There was no statistically significant effect of BMP on K6 scores at 16- weeks (mean difference 1.17, 95% confidence interval: - 0.63 to 2.98, P = 0.19). Exploratory analyses revealed that BMP reduced depressive symptoms in family members at 8- weeks (difference = - 3.37, 95%CI -6.32 to - 0.43, P = 0.02) and improved family functioning at multiple time points (Role; 8 W, difference = - 0.13, 95%CI -0.26 to - 0.00, P = 0.04, Affective Responsiveness; 8 W, difference = - 0.24, 95%CI -0.43 to - 0.05, P = 0.01, 32 W, difference = - 0.22, 95%CI -0.41 to - 0.03, P = 0.02, Behavior Control; 16 W, difference = - 0.17, 95%CI -0.34 to - 0.00, P = 0.04). CONCLUSIONS Four BMP sessions did not significantly reduce the psychological distress of family members of patients with chronic MDD.

Abstract
BACKGROUND/AIM One mechanism of the anticancer action of anthracyclines is believed to be oxidative DNA damage. Previously, we reported that doxorubicin induced oxidative DNA damage in the presence of Cu(II). However, the mechanism of pirarubicin-induced oxidative DNA damage has not been well clarified. MATERIALS AND METHODS DNA damage by pirarubicin in the presence of Cu(II) was analyzed using pBR322 plasmid DNA. O2•- derived from pirarubicin in the presence of Cu(II) was detected by cytochrome c reduction. RESULTS Pirarubicin induced DNA damage in the presence of Cu(II). Scavenger experiments suggest that reactive species are generated from H2O2 and Cu(I). Pirarubicin induced O2•- production in the presence of Cu(II). CONCLUSION These findings suggest that pirarubicin plus Cu(II) induces oxidative DNA damage in a similar manner to doxorubicin, and Cu(II)-mediated oxidative DNA damage may serve as a common mechanism for antitumor effects of anthracyclines.

Abstract
Clinical effect and safety of recombinant human erythropoietin (r-HuEPO) were evaluated in 66 hemodialysis patients with intractable anemia. Initially, 50U/kg dry weight (DW) of r-HuEPO was administered intravenously at the end of every hemodialysis procedure for 4 weeks, then the dosage was increased to 100 and 200U/kg DW for poor responders. The patients’ hematocrits rose from 19.8 ± 2.3% (pretreatment) to 30.2 ± 4.9% after 12 weeks. From 206 U of blood transfusion requirement in the 3-month period before the study, only 34 U were needed after treatment. Serum iron and ferritin levels fell significantly during the study, and iron storage was considered to be one of the decisive factors in the response to r-HuEPO. Blood pressure rose in the course of r-HuEPO administration, but uncontrollable hypertension was rarely observed. There was no significant adverse effect of r-HuEPO except for this mild hypertension. These results indicate that r-HuEPO is an excellent therapeutic aid for the anemia associated with chronic renal failure.

Abstract
BACKGROUND Handgrip strength is a simple measurement of overall muscular strength and is used to detect sarcopenia. It also predicts adverse events in later life. Many mechanisms of sarcopenia development have been reported. A hypertensive status impairs endothelial dysfunction, which might deteriorate skeletal muscle if vascular angiogenesis is not maintained. OBJECTIVES This study investigated muscle strength and circulating CD34-positive cells as a marker of vascular angiogenesis. DESIGN Cross-sectional study. PARTICIPANTS 262 male Japanese community dwellers aged 60 to 69 years. MEASUREMENTS The participants' handgrip strength, medical history, and blood samples were taken. We stratified the participants by hypertensive status to investigate the association between handgrip strength and circulating CD34-positive cells according to hypertensive status. Pearson correlation and linear regression analyses were used. RESULTS In the Pearson correlation analysis, handgrip strength and the logarithm of circulating CD34-positive cells were significantly associated in hypertensive participants (r=0.22, p=0.021), but not in non-hypertensive participants (r=-0.01, p=0.943). This relationship was only significant in hypertensive participants (ß=1.94, p=0.021) in the simple linear regression analysis, and it remained significant after adjusting for classic cardiovascular risk factors (ß=1.92, p=0.020). The relationship was not significant in non-hypertensive participants (ß=-0.09, p=0.903). CONCLUSIONS We found a positive association between handgrip strength and circulating CD34-positive cells in hypertensive men. Vascular maintenance attributed by circulating CD34-positive cells is thought to be a background mechanism of this association after hypertension-induced vascular injury in skeletal muscle.

Abstract
A 70-year-old man presented to our clinic with a 10-year history of recurrent pruritic erythema and plaques on his trunk and limbs. Based on the pathological findings and monoclonal rearrangement of the T-cell receptor (TCR)-Cβ1 gene, mycosis fungoides (T2N0M0B0 stage IB) was diagnosed. Despite combination therapy including histone deacetylase inhibitor (vorinostat), the symptoms slowly evolved into Sézary syndrome (SS; T4N1M0B2) over 4 years, with dense infiltrates due to atypical lymphocytes expressing CCR4 developing in the entire dermis. Anti-CCR4 monoclonal antibody (mogamulizumab) treatment was started. After seven courses, the CCR4-positive atypical lymphocytes decreased in the dermis to levels below those seen at the outset of treatment. To our knowledge, there is no previous report of a case of SS managed with vorinostat followed by mogamulizumab demonstrating such a remarkable change in the pathological state following treatment.

Abstract
Centrifugal lipodystrophy (CLD), characterized by a depressed lesion in the abdominal skin, is a chronic disease occurring more often among younger patients of East Asian descent. We present an extremely unusual case of CLD of the scalp associated with reversible hair loss. The patient demonstrated alopecia in the frontal, temporal and occipital areas of the scalp, which connected to form a ring-shaped area of hair loss. Curiously, the area of hair loss gradually expanded outwards while the central region showed normal hair regrowth. Immunohistochemical analysis demonstrated reduced expression of leptin, an adipokine capable of inducing the anagen phase of the hair cycle, in the adipose tissue, associated with active inflammation. By contrast, recovery of leptin expression was observed at sites of healed inflammatory lesions, suggesting that reversible hair loss might be caused by a change in leptin expression in adipose tissue.

Abstract
BACKGROUND/AIM Pirarubicin (THP) has shown equal or superior cytotoxicity compared to doxorubicin. One of the main anticancer actions of doxorubicin is believed to be involved in ROS (reactive oxygen species) generation. Therefore, the anticancer mechanisms of THP may involve ROS generation. The aim of this study was to clarify the mechanisms of THP-induced apoptosis through ROS generation. MATERIALS AND METHODS We analyzed the apoptotic events induced by THP in HL-60 cells and HP100 cells, hydrogen peroxide (H2O2)-resistant cells derived from HL-60. RESULTS The apparent cytotoxicity could be detected at above 0.1 μM in HL-60 cells after 24-h incubation, whereas it was suppressed under these conditions in HP100 cells. In HP100 cells, THP-induced apoptosis, evaluated by DNA ladder formation, H2O2 generation, mitochondrial membrane potential decrease and caspase-3/7 activity, was suppressed or delayed compared to those of HL-60 cells. CONCLUSION These findings can be explained by the involvement of H2O2 generation in the THP apoptotic pathway. This is the first report on THP-induced apoptosis through the H2O2 generation.

Abstract
Immunotherapeutic approaches, particularly PD-1/PD-L1 blockade, have improved the treatment of non-small cell lung cancer (NSCLC), supporting the premise that evasion of immune destruction is of importance for NSCLC progression. However, the signals responsible for upregulation of PD-L1 in NSCLC cells and whether they are integrated with the regulation of other immune-related genes are not known. Mucin 1 (MUC1) is aberrantly overexpressed in NSCLC, activates the NF-κB p65→ZEB1 pathway and confers a poor prognosis. The present studies demonstrate that MUC1-C activates PD-L1 expression in NSCLC cells. We show that MUC1-C increases NF-κB p65 occupancy on the CD274/PD-L1 promoter and thereby drives CD274 transcription. Moreover, we demonstrate that MUC1-C-induced activation of NF-κB→ZEB1 signaling represses the TLR9, IFNG, MCP-1 and GM-CSF genes, and that this signature is associated with decreases in overall survival. In concert with these results, targeting MUC1-C in NSCLC tumors suppresses PD-L1 and induces these effectors of innate and adaptive immunity. These findings support a previously unrecognized central role for MUC1-C in integrating PD-L1 activation with suppression of immune effectors and poor clinical outcome.

Abstract
Recent schizophrenia (SCZ) studies have reported an increased burden of de novo copy number variants (CNVs) and identified specific high-risk CNVs, although with variable phenotype expressivity. However, the pathogenesis of SCZ has not been fully elucidated. Using array comparative genomic hybridization, we performed a high-resolution genome-wide CNV analysis on a mainly (92%) Japanese population (1699 SCZ cases and 824 controls) and identified 7066 rare CNVs, 70.0% of which were small (<100 kb). Clinically significant CNVs were significantly more frequent in cases than in controls (odds ratio=3.04, P=9.3 × 10-9, 9.0% of cases). We confirmed a significant association of X-chromosome aneuploidies with SCZ and identified 11 de novo CNVs (e.g., MBD5 deletion) in cases. In patients with clinically significant CNVs, 41.7% had a history of congenital/developmental phenotypes, and the rate of treatment resistance was significantly higher (odds ratio=2.79, P=0.0036). We found more severe clinical manifestations in patients with two clinically significant CNVs. Gene set analysis replicated previous findings (e.g., synapse, calcium signaling) and identified novel biological pathways including oxidative stress response, genomic integrity, kinase and small GTPase signaling. Furthermore, involvement of multiple SCZ candidate genes and biological pathways in the pathogenesis of SCZ was suggested in established SCZ-associated CNV loci. Our study shows the high genetic heterogeneity of SCZ and its clinical features and raises the possibility that genomic instability is involved in its pathogenesis, which may be related to the increased burden of de novo CNVs and variable expressivity of CNVs.

Abstract
The Wingless/integrase-1 (Wnt) family of protein ligands and their functional antagonists, secreted frizzled-related proteins (sFRPs), regulate various biological processes ranging from embryonic development to immunity and inflammation. Wnt5a and sFRP5 comprise a typical ligand/antagonist pair, and the former molecule was recently detected at the messenger RNA (mRNA) level in human periodontitis. The main objective of this study was to investigate the interrelationship of expression of Wnt5a and sFRP5 in human periodontitis (as compared to health) and to determine their roles in inflammation and bone loss in an animal model. We detected both Wnt5a and sFRP5 mRNA in human gingiva, with Wnt5a dominating in diseased and sFRP5 in healthy tissue. Wnt5a and sFRP5 protein colocalized in the gingival epithelium, suggesting epithelial cell expression, which was confirmed in cultured human gingival epithelial cells (HGECs). The HGEC expression of Wnt5a and sFRP5 was differentially regulated by a proinflammatory stimulus (lipopolysaccharide [LPS] from Porphyromonas gingivalis) in a manner consistent with the clinical observations (i.e., LPS upregulated Wnt5a and downregulated sFRP5). In HGECs, exogenously added Wnt5a enhanced whereas sFRP5 inhibited LPS-induced inflammation, as monitored by interleukin 8 production. Consistent with this, local treatment with sFRP5 in mice subjected to ligature-induced periodontitis inhibited inflammation and bone loss, correlating with decreased numbers of osteoclasts in bone tissue sections. As in humans, mouse periodontitis was associated with high expression of Wnt5a and low expression of sFRP5, although this profile was reversed after treatment with sFRP5. In conclusion, we demonstrated a novel reciprocal relationship between sFRP5 and Wnt5a expression in periodontal health and disease, paving the way to clinical investigation of the possibility of using the Wnt5a/sFRP5 ratio as a periodontitis biomarker. Moreover, we showed that sFRP5 blocks experimental periodontal inflammation and bone loss, suggesting a promising platform for the development of a new host modulation therapy in periodontitis.
