RESUMO

Background: Endoscopic submucosal tunnel dissection (ESTD) has recently been an effective procedure for resecting large early esophageal neoplasm. However, excessive dissection beyond the distal limit may occur because the prepared distal end often cannot be distinguished through the tunnel. This study aimed to assess the efficacy and safety of a novel crystal violet navigation (CVN) for identifying the distal end.Material and methods: In the observational case series study, all 22 patients who underwent esophageal ESTD using the CVN were included. When setting the distal end, the distal incision line was dyed purple using a crystal violet solution. The rates of purple color identified via the tunnel, successful tunnel penetration without extra dissection, en bloc and curative resection, procedure time for ESTD and CVN, and procedure-associated complications were evaluated.Results: The rates of purple color and successful tunnel penetration were both 100%. En bloc and curative resection were 100%, and 86%, respectively. The mean total procedure time was 103.9 ± 46.2 (mean ± SD) minutes, while the mean time for the CVN was 14.1 ± 3.44 s. No complications were observed.Conclusions: The simple CVN method can be a navigation tool for identifying the distal end during the ESTD procedure.

RESUMO

The glucose-lowering effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors is reduced in patients with diabetes who have chronic kidney disease (CKD). In the present study, we examined the effect of an SGLT2 inhibitor on the salt sensitivity of blood pressure (BP), circadian rhythm of BP, and sympathetic nerve activity (SNA) in nondiabetic CKD rats. Uninephrectomized Wistar rats were treated with adenine (200 mg/kg/day) for 14 days. After stabilization with a normal-salt diet (NSD, 0.3% NaCl), a high-salt diet (HSD, 8% NaCl) was administered. Mean arterial pressure (MAP) was continuously monitored using a telemetry system. We also analyzed the low frequency (LF) of systolic arterial pressure (SAP), which reflects SNA. In adenine-induced CKD rats, HSD consumption for 5 days significantly increased the mean MAP from 106 ± 2 to 148 ± 3 mmHg. However, MAP was decreased to 96 ± 3 mmHg within 24 h after switching back to a NSD (n = 7). Treatment with an SGLT2 inhibitor, luseogliflozin (10 mg/kg/day, p.o., n = 7), significantly attenuated the HSD-induced elevation of MAP, which was associated with a reduction in LF of SAP. These data suggest that treatment with an SGLT2 inhibitor attenuates the salt sensitivity of BP, which is associated with SNA inhibition in nondiabetic CKD rats.

RESUMO

Previously we studied the possible neuroprotective effects of ischemia-resistant exercise in a gerbil model of transient whole-brain ischemia and evaluated the histology, expression of specific proteins, and brain function under different conditions. The present study investigated the neuroprotective effects of light exercise, without lactate elevation, in a gerbil model of ischemia/reperfusion injury. Transient whole-brain ischemia was induced by occlusion of the bilateral common carotid arteries for 5 min. A group of animals was subjected to treadmill exercise before ischemia induction. Hippocampal neuronal damage and miRNA expression, as well as behavioral deficits and plasma lactate levels, were evaluated. Light exercise suppressed hippocampal neuron loss and preserved short-term memory. Moreover, 14 miRNAs (mmu-miR-211-3p, -327, -451b, -711, -3070-3p, -3070-2-3p, -3097-5p, -3620-5p, -6240, -6916-5p, -6944-5p, 7083-5p, -7085-5p, and -7674-5p) were upregulated and 6 miRNAs (mmu-miR-148b-3p, -152-3p, -181c-5p, -299b-5p, -455-3p, and -664-3p) were downregulated due to ischemia. However, the expression of these miRNAs remained unchanged when animals performed light exercise before the ischemic event. Differentially expressed miRNAs regulate multiple biological processes such as inflammation, metabolism, and cell death. These findings suggest that light exercise reduces neuronal death and behavioral deficits after transient ischemia by regulating hippocampal miRNAs.

RESUMO

BACKGROUND AND AIM: The presence of cirrhosis is an important factor for the management of patients with hepatitis C virus (HCV) infection and it determines the duration of treatment for HCV with the direct-acting antiviral (DAA) regimen of glecaprevir (GLE) and pibrentasvir (PIB), that is, 8 or 12 weeks, if patients do not have a history of DAA failure. However, in real-world settings, determination of cirrhosis depends on the discretion of the attending hepatologists, and it is unclear whether compensated cirrhosis was homogenously diagnosed or not. In this study, we investigated the real-world diagnosis of cirrhosis by characterizing DAA-naïve patients who underwent a 12-week GLE/PIB regimen in whom cirrhosis was diagnosed, comparing their characteristics with those of patients who underwent an 8-week regimen in whom cirrhosis was absent. METHODS: In a large, multicenter cohort study, we compared background characteristics and treatment outcomes among DAA-naïve patients who underwent an 8-week versus a 12-week GLE/PIB regimen. RESULTS: Among 977 patients enrolled, 296 (30.3%) were determined to have cirrhosis and underwent a 12-week regimen. Some patient characteristics largely overlapped between the two groups, including liver fibrosis indices. Sustained viral response rates were similar between groups after adjusting liver fibrosis index with propensity score matching. CONCLUSION: Although adequately diagnosed, the determination of cirrhosis varied widely among institutions or by hepatologists in real-world settings, and the severity of liver fibrosis overlapped significantly between patients in whom compensated cirrhosis was determined to be present and patients in whom cirrhosis was absent. Virologic efficacy was similar after adjusting for the degree of liver fibrosis.

RESUMO

Hepatitis B virus (HBV)-related hepatocarcinogenesis is not necessarily associated with the liver fibrotic stage and is occasionally seen at early fibrotic stages. MicroRNAs (miRNAs) are essentially 18- to 22-nucleotide-long endogenous noncoding RNAs. Aberrant miRNA expression is a common feature of various human cancers. The aberrant expression of specific miRNAs has been shown in hepatocellular carcinoma (HCC) tissue compared with nontumor tissue. Thus, we examined targetable miRNAs as a potential new biomarker related to the high risk of HBV-related hepatocarcinogenesis, toward the prevention of cancer-related deaths. HCC tissue samples from 29 patients who underwent hepatectomy at our hospital in 2002-2013 were obtained. We extracted the total RNA and analyzed it by microRNA array, real-time RT-PCR, and three comparisons: 1) HBV-related HCC and adjacent nontumor tissue, 2) HCV-related HCC and adjacent nontumor tissue, and 3) non-HBV-, non-HCV-related HCC and adjacent nontumor tissue. We also performed a functional analysis of miRNAs specific for HBV-related HCC by using HBV-positive HCC cell lines. MiR-210-3p expression was significantly increased only in the HBV-related HCC tissue samples. MiR-210-3p expression was upregulated, and the levels of its target genes were reduced in the HBV-positive HCC cells. The inhibition of miR-210-3p enhanced its target gene expression in the HBV-positive HCC cells. In addition, miR-210-3p regulated the HBx expression in HBV-infected Huh7/NTCP cells. The enhanced expression of miR-210-3p was detected specifically in HBV-related HCC and regulated various target genes, including HBx in the HBV-positive HCC cells. MiR-210-3p might, thus, be a new biomarker for the risk of HBV-related HCC.NEW & NOTEWORTHY Our present study demonstrated that miR-210-3p is the only microRNA with enhanced expression in HBV-related HCC, and the enhanced expression of miR-210-3p upregulates HBx expression. Therefore, miR-210-3p might be a pivotal biomarker of HBV-related hepatocarcinogenesis, and the inhibition of miR-210-3p could prevent inducing hepatocarcinogenesis related to HBV infection.

RESUMO

BACKGROUND/AIM: Pancreatic neuroendocrine tumors (pNETs) are rare pancreatic neoplasms, and therapeutic options for pNETs are limited. Metformin is an anti-hypoglycemic drug that appears to have anticancer effects. However, little is known about the effect of metformin on pNETs. In this study, we investigated the anti-proliferative effect of metformin on a human pNET cell line. MATERIALS AND METHODS: The anti-proliferative properties of metformin were evaluated in QGP-1 and NCI-H727 cells using a cell counting kit-8 assay. Xenograft mouse models were used to assess the tumor effect in vivo. RESULTS: Metformin inhibited the proliferation and anti-tumor growth of QGP-1 cells, accompanied by their arrest during the cell cycle at the G0/G1 phase. Immunohistochemical analysis of tumor tissues revealed down-regulation of cyclin D1 and proliferating cell nuclear antigen in the metformin-treated group. Additionally, metformin induced apoptosis, and the expression of survivin and claspin were decreased in metformin-treated QGP-1 cells according to the apoptosis array. Furthermore, the angiogenic related protein TIMP-1 was down-regulated, and its miRNA expression was altered by metformin in QGP-1 cells. CONCLUSION: Taken together, our study demonstrated the therapeutic potential of metformin and provides molecular mechanistic insights into its anti-tumoral effect on pNETs. This study is the first one describing anti-tumoral effects in pNETs.

RESUMO

We examined the effects of the angiotensin receptor-neprilysin inhibitor LCZ696 on overt proteinuria and renal injury in type 2 diabetic Otsuka-Long- Evans-Tokushima-Fatty (OLETF) rats. Aged OLETF rats were also treated with either valsartan or valsartan plus hydralazine for comparison. LCZ696 caused greater attenuation of the progression of proteinuria than either valsartan alone or valsartan combined with hydralazine. Reduced glomerular injury and tubulointerstitial fibrosis were also observed in LCZ696-treated rats. Moreover, LCZ696 prevented increases in blood urea nitrogen (BUN) and creatinine levels. These data suggest that LCZ696 elicits a reno-protective effect against type 2 diabetes with overt proteinuria.

RESUMO

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) has become a standard treatment for early gastric neoplasia. However, as the upper and middle body of the greater curvature has a rich vasculature and submucosal fibrosis, ESD of neoplasia in these locations requires a specific strategy. We aimed to investigate the efficacy and safety of the J-shaped superficial cutting and splashed submucosal dissection (JSCS) technique for neoplasia of the greater curvature by comparing ESD using JSCS with conventional ESD. METHODS: Twenty-two patients who underwent ESD for gastric neoplasia affecting the upper and middle body of the greater curvature were divided into two groups for retrospective analysis. Nine patients underwent conventional ESD (c-Group), while 13 underwent ESD with JSCS (j-Group). Primary outcome was the en bloc resection rate. Secondary outcomes included complete resection (R0) rate, procedure time, perforation rate, total bleeding time, and the total number of massive bleeding events and of hemostatic forceps times applied during ESD. RESULTS: There were no significant differences between both groups (c-Group vs j-Group) in en bloc resection rate, or R0 resection rate. Compared with the c-Group, the j-Group tended to have a decreased mean procedure time (mean 133 minutes vs 74 minutes, p=0.11) and perforation rate (11% vs 0%, p=0.41). Compared with the c-Group, the j-Group had significantly fewer bleeding incidents (13.4 times vs 6.6 times, p=0.0095), shorter total bleeding time (17.6 min vs 7.4 min, p=0.036), and fewer usages of hemostatic forceps (6.3 times vs 2.4 times, p=0.026) during ESD. CONCLUSION: Endoscopic submucosal dissection with JSCS is superior to conventional ESD, as it reduces intraprocedural bleeding. This technique has the potential to become the standard strategy for neoplasia affecting the upper and middle body of the greater curvature.

RESUMO

Gallbladder cancer is the most common biliary tract cancer with poor prognosis and wide variation in incidence rates worldwide, being very high in some countries in Latin America and Asia. Treatment of type 2 diabetes with metformin causes a reduction in the incidence of cancer. Till date, there are no reports on the anti-tumor effects of metformin in gall bladder cancer. Therefore, this study evaluated the effects of metformin on the proliferation of human gallbladder adenocarcinoma cells in vitro and in vivo, as well as explored the microRNAs associated with the anti-tumor effects of metformin. Metformin inhibited the proliferation in gallbladder adenocarcinoma cell lines NOZ, TGBC14TKB, and TGBC24TKB, and blocked the G0 to G1 transition in the cell cycle. This was accompanied by strong reduction in the expression of G1 cyclins, especially cyclin D1 and its catalytic subunits including cyclin-dependent kinase 4, and in retinoblastoma protein phosphorylation. In addition, metformin reduced the phosphorylation of receptor tyrosine kinases, especially Tie-2, ALK, PYK, EphA4, and EphA10, as well as angiogenesis-related proteins, including RANTES, TGF-ß, and TIMP-1. Moreover, metformin also markedly altered microRNA expression profile leading to an anti-tumor effect. Treatment of athymic nude mice bearing xenograft tumors with metformin inhibited tumor growth. These results suggest that metformin may be used clinically for the treatment of gallbladder adenocarcinoma.

RESUMO

BACKGROUND: The perioperative factors predicting or influencing early pancreatic ductal adenocarcinoma recurrence are unclear. This study attempted to identify the predictive factors for early pancreatic ductal adenocarcinoma recurrence post-pancreatectomy and the influence of pre- and post- operative adjuvant therapy. METHODS: One hundred and fifteen patients undergoing curative resection for pancreatic ductal adenocarcinoma between 2000 and 2016 at our institution were retrospectively analyzed. Patients were divided into two groups: those who did (n = 34) and did not (n = 81) experience a recurrence within 6 months postoperatively. RESULTS: Multivariate analyses demonstrated postoperative CA19-9 de-normalization, no postoperative adjuvant chemotherapy, and serosal invasion were independent risk factors for early recurrence (P < 0.001, P = 0.001, and P = 0.010, respectively). A subgroup analysis showed patients with (n = 51) and without (n = 64) preoperative chemoradiotherapy had different predictors. Although postoperative adjuvant chemotherapy was not a significant indicator in patients with preoperative chemoradiotherapy, CA19-9 de-normalization and no postoperative adjuvant chemotherapy were significant indicators in patients without preoperative chemotherapy. Preoperative chemotherapy strongly prevented early local recurrence while postoperative adjuvant chemotherapy prevented early distant recurrence. CONCLUSIONS: CA19-9 de-normalization was an important predictor of early recurrence of pancreatic ductal adenocarcinoma. Although postoperative adjuvant chemotherapy was an important preventive measure against early recurrence, particularly for distant recurrence, preoperative chemoradiotherapy could strongly prevent the early local recurrence of pancreatic ductal adenocarcinoma. These perioperative adjuvant therapies could have a complementary relationship.

RESUMO

AIM: The incidence of hepatitis C virus (HCV) infection is much higher in hemodialysis patients than that in healthy individuals. The prognosis of hemodialysis patients with HCV infection is poorer than that without HCV infection. Therefore, antiviral intervention is pivotal for HCV infection in hemodialysis patients. Recent evaluations of the pangenotypic regimen of glecaprevir/pibrentasvir show that it is highly effective and safe for HCV-infected hemodialysis patients. However, a few reports showed that the effect of HCV elimination by glecaprevir/pibrentasvir improved liver dysfunction or anemia. The aim of the present study was to determine clinical outcomes after HCV elimination using the glecaprevir/pibrentasvir regimen in HCV-infected hemodialysis patients. METHODS: This study was a retrospective, six-center study conducted in Japan, in which 24 hemodialysis patients with HCV genotype 1-2 treated with glecaprevir/pibrentasvir were recruited. Blood examinations were performed at end of treatment (EOT), and at 3, 6, and 12 months post-treatment during the 12-month follow-up period. RESULTS: The overall sustained virologic response rate was 100% (24/24). During the DAA treatment period, adverse events were observed in 20.8% of patients (5/24), and pruritus was the most frequently observed in 12.5% (3/24). Interestingly, we observed an improved control of anemia after EOT with a significant increase in hemoglobin levels. In addition, total bilirubin was diminished, and platelet counts and albumin, total cholesterol, and alpha-fetoprotein levels remained unchanged after EOT in hemodialysis patients. Furthermore, erythropoietin concentration was not increased after EOT. CONCLUSIONS: HCV elimination using glecaprevir/pibrentasvir treatment might be a major breakthrough for the control of anemia in hemodialysis patients.

RESUMO

AIMS/INTRODUCTION: Clinical studies have shown that treatment with inhibitors of sodium-glucose cotransporter 2 (SGLT2) significantly increases the hematocrit in patients with type 2 diabetes. To investigate whether SGLT2 inhibitors directly promote erythropoietin production independently on blood glucose reduction, the hematopoietic effect of the specific SGLT2 inhibitor, luseogliflozin, was examined in non-diabetic rats with renal anemia. MATERIALS AND METHODS: Renal anemia was induced by treatment with adenine (200 or 600 mg/kg/day, orally for 10 days) in non-diabetic Wistar-Kyoto or Wistar rats, respectively. Luseogliflozin (10 mg/kg bodyweight) or vehicle (0.5% carboxymethyl cellulose) was then administered for 6 weeks. The hematocrit and the hemoglobin (Hb), blood urea nitrogen, plasma creatinine, and plasma erythropoietin levels were monitored. RESULTS: Treatment with adenine decreased the hematocrit and the Hb level, which were associated with increases in the blood urea nitrogen and plasma creatinine levels. In Wistar-Kyoto rats treated with 200 mg/kg/day adenine, administration of luseogliflozin induced glycosuria, but did not change the blood urea nitrogen, plasma creatinine levels, hematocrit, Hb or plasma erythropoietin levels. Similarly, luseogliflozin treatment failed to change the hematocrit or the Hb levels in Wistar rats with renal anemia induced by 600 mg/kg/day of adenine. Plasma erythropoietin concentrations were also not different between luseogliflozin- and vehicle-treated rats. Similarly, in human erythropoietin-producing cells derived from pluripotent stem cells, luseogliflozin treatment did not change the erythropoietin level in the medium. CONCLUSIONS: These data suggest that SGLT2 inhibitor fails to exert hematopoietic effects in non-diabetic conditions.

RESUMO

OBJECTIVE: The goal of this retrospective study was to clarify the clinical implications of immunohistochemically detected protein expression for genes that are frequently mutated in pancreatic neuroendocrine tumors (PNETs). BACKGROUND: The clinical management of PNETs is hindered by their heterogenous biological behavior. Whole-exome sequencing recently showed that 5 genes (DAXX/ATRX, MEN1, TSC2, and PTEN) are frequently mutated in PNETs. However, the clinical implications of the associated alterations in protein expression remain unclear. METHODS: We collected Grade 1 and 2 (World Health Organization 2017 Classification) primary PNETs samples from 100 patients who underwent surgical resection. ATRX, DAXX, MEN1, TSC2, and PTEN expression were determined immunohistochemically to clarify their relationships with prognosis and clinicopathological findings. RESULTS: Kaplan-Meier analysis indicated that loss of TSC2 (n = 58) or PTEN (n = 37) was associated with significantly shorter overall survival, and that loss of TSC2 or ATRX (n = 41) was associated with significantly shorter recurrence-free survival. Additionally, loss of ATRX or TSC2 was significantly associated with nodal metastasis. In a multivariate analysis, combined loss of TSC2 and ATRX (n = 31) was an independent prognostic factor for shorter recurrence-free survival (hazard ratio 10.1, 95% confidence interval 2.1-66.9, P = 0.003) in G2 PNETs. CONCLUSIONS: Loss of ATRX, TSC2, and PTEN expression might be useful as a method of clarifying the behavior and clinical outcomes of Grade 1 and 2 PNETs in routine clinical practice. Combined loss of TSC2 and ATRX had an especially strong, independent association with shorter recurrence-free survival in patients with G2 PNETs. Loss of pairs in ATRX, TSC2, or PTEN would be useful for selecting the candidate for postoperative adjuvant therapy.

RESUMO

The prognosis of hepatocellular carcinoma (HCC) patients exhibiting macroscopic vascular invasion (MVI) is poor, and the most appropriate treatment approach remains unclear. The current study aimed to investigate the efficacy and safety of sorafenib treatment following chemoradiotherapy for advanced HCC exhibiting MVI. A newly reported regimen, including 5-fluorouracil and cisplatin therapy (NewFP), plus three-dimensional conformal radiotherapy (3D-CRT) for MVI was used as the initial treatment. Additionally, sorafenib, as a secondary treatment, was administered after NewFP plus 3D-CRT for MVI. The present retrospective study enrolled patients with unresectable advanced HCC that was treated with NewFP plus 3D-CRT for MVI between January 2009 and December 2017. In total, 32 HCC patients with MVI were registered. Of these 32 patients, 18 were treated with NewFP plus 3D-CRT for MVI (NewFP + 3D-CRT group) and 14 were treated with sorafenib following NewFP plus 3D-CRT for MVI (sorafenib after NewFP + 3D-CRT group). The study endpoints were overall survival, overall response rate and disease control rate. Clinical factors influencing overall survival were identified using univariate and multivariate analyses. The median survival time in the NewFP + 3D-CRT group and sorafenib following NewFP + 3D-CRT group was 6.7 and 49.2 months, respectively (P=0.0003). For patients with advanced HCC exhibiting MVI, the initial treatment with NewFP plus 3D-CRT for MVI was well tolerated. The administration of sorafenib as the secondary treatment following NewFP plus 3D-CRT for MVI was associated with a significantly higher overall response rate, disease control rate and increased overall survival as compared with the NewFP plus 3D-CRT treatment.

RESUMO

BACKGROUND: In clinical trials, a pangenotype direct-acting antiviral (DAA) regimen consisting of glecaprevir (GLE) and pibrentasvir (PIB) exhibited high virologic efficacy and tolerability in patients with hepatitis C virus (HCV) infection. This study sought to confirm these findings in real-world settings, focusing on patients with cirrhosis, history of DAA failure, or HCV genotype 3 who were treated with a 12-week regimen in a large multicenter study from Japan. METHODS: In a nationwide multicenter prospective cohort study, we analyzed background characteristics, tolerability, and treatment outcome of patients who underwent a 12-week GLE/PIB regimen. RESULTS: Of 1190 patients, 509 (42.8%) underwent the 12-week regimen, and the remaining patients underwent an 8-week regimen. The rate of sustained virologic response (SVR) of patients treated with the 12-week regimen was 99.0%, comparable with that of patients treated with the 8-week regimen. The adverse events were observed in 29.1% of patients. The main adverse event was pruritus, which was observed in 14.7%. Ten patients (2.0%) discontinued therapy during treatment period. CONCLUSION: The 12-week GLE/PIB regimen was well-tolerated with high virologic efficacy in patients with cirrhosis, experience of DAA, or HCV genotype 3; tolerability and SVR rate were comparable with those of DAA-naïve, non-cirrhotic, non-genotype 3 patients who underwent 8-week regimen.

RESUMO

The coexistence of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis and anti-myelin oligodendrocyte glycoprotein antibody (MOG-Ab)-associated diseases has been reported. We report the case of a 36-year-old woman who presented with repeated typical anti-NMDAR encephalitis coexisting with unusual symptoms not consistent with anti-NMDAR encephalitis. Apart from the anti-NMDAR encephalitis, her first episode was characterized by balance disability with bilateral medial frontal cortical lesions, suggesting the involvement of the cortico-reticular projections and the basal ganglia-brainstem projections. The second episode presented with Broca's aphasia caused by involvement of the Broca's area and lower part of the precentral gyrus. The detection of MOG-Ab in both episodes suggested the coexistence of MOG-Ab-associated diseases. Thus, an evaluation of MOG-Ab should be considered when anti-NMDAR encephalitis presenting with atypical symptoms is encountered.

RESUMO

Albumin-bilirubin (ALBI) grade is defined using the ALBI score, which is calculated based on total serum bilirubin and albumin. This study aimed to evaluate the diagnostic ability of the ALBI score for determining hepatic fibrosis stage and transplant-free survival in primary biliary cholangitis (PBC) patients. A total of 181 Japanese patients with biopsy-proven or serologically diagnosed PBC were enrolled. The pathological stage was assessed using the Scheuer classification. The ALBI score differentiated fibrosis in stage 4 from that of 3 in the biopsy-proven cohort (p < 0.05). With an ALBI score cut-off value of -1.679, the sensitivity and specificity were 100% and 91.1%, respectively, with a likelihood ratio of 12.3 to differentiate stage 4 from stages 1-3. The ALBI score at the beginning of ursodeoxycholic acid (UDCA) prescription correlated with the two prognostic scores calculated after 1-year UDCA treatment. Kaplan-Meier analysis showed that the baseline ALBI score differentiated liver transplant-free survival (p < 0.05). The ALBI score presented a greater hazard ratio for transplant-free survival than aspartate aminotransferase-to-platelet ratio index (APRI) in Cox proportional hazard model. In conclusion, ALBI score indicates pathological stage in Japanese PBC patients and scores before UDCA prescription predict better liver transplant-free survival, which correlated well with the two major prognostic scores. The prognosis-predicting ability of the ALBI score might surpass that of APRI.
