Impact of Bacille Calmette-Guérin vaccination on the therapeutic schedule of infantile epileptic spasms syndrome: A 25-year Japanese single-center survey.

Adrenocorticotropic hormone (ACTH) therapy is effective for infantile epileptic spasms syndrome (IESS) but can induce immunosuppression. In Japan, Bacille Calmette-Guérin (BCG) vaccination, modified in 2013 to reduce osteitis/osteomyelitis risk, coincides with the peak onset age of IESS. This raises concerns about infection risks when administering ACTH therapy post-vaccination.

Microfluidic device for the high-throughput and selective encapsulation of single target cells.

Droplet-based microfluidic technologies for encapsulating single cells have rapidly evolved into powerful tools for single-cell analysis. In conventional passive single-cell encapsulation techniques, because cells arrive randomly at the droplet generation section, to encapsulate only a single cell with high precision, the average number of cells per droplet has to be decreased by reducing the average frequency at which cells arrive relative to the droplet generation rate. Therefore, the encapsulation efficiency for a given droplet generation rate is very low.

Lysosomal cholesterol overload in macrophages promotes liver fibrosis in a mouse model of NASH.

Accumulation of lipotoxic lipids, such as free cholesterol, induces hepatocyte death and subsequent inflammation and fibrosis in the pathogenesis of nonalcoholic steatohepatitis (NASH). However, the underlying mechanisms remain unclear. We have previously reported that hepatocyte death locally induces phenotypic changes in the macrophages surrounding the corpse and remnant lipids, thereby promoting liver fibrosis in a murine model of NASH.

Time-course changes in liver functional reserve after successful sofosbuvir/velpatasvir treatment in patients with decompensated cirrhosis.

Aim: Direct-acting antivirals (DAAs) are currently available even for patients with decompensated cirrhosis. Reportedly, hepatic functional reserve improved in the short term after achievement of sustained virologic response (SVR). We aimed to clarify the outcomes after achievement of SVR in patients with decompensated cirrhosis who were treated by DAAs in real-world clinical practice.

A novel noninvasive formula for predicting cirrhosis in patients with chronic hepatitis C.

Evaluating liver fibrosis is crucial for disease severity assessment, treatment decisions, and hepatocarcinogenic risk prediction among patients with chronic hepatitis C. In this retrospective multicenter study, we aimed to construct a novel model formula to predict cirrhosis. A total of 749 patients were randomly allocated to training and validation sets at a ratio of 2:1.

Analysis of the safety of pretransplant corticosteroid therapy in patients with acute liver failure and late-onset hepatic failure in Japan.

Background And Aim: In Japan, corticosteroids have been commonly used as a part of multidisciplinary therapy for patients with acute liver failure and late-onset hepatic failure. However, there is controversy regarding the development of infections and other complications. In this study, the influence of corticosteroids on patient outcomes after liver transplantation was investigated.

Cost-effectiveness of a "treat-all" strategy using Direct-Acting Antivirals (DAAs) for Japanese patients with chronic hepatitis C genotype 1 at different fibrosis stages.

Aim: To evaluate the cost-effectiveness of therapeutic strategies initiated at different stages of liver fibrosis using three direct-acting antivirals (DAAs), sofosbuvir-ledipasvir (SL), glecaprevir-pibrentasvir (GP), and elbasvir plus grazoprevir (E/G), for Japanese patients with chronic hepatitis C (CHC) genotype 1.

Methods: We created an analytical decision model reflecting the progression of liver fibrosis stages to evaluate the cost-effectiveness of alternative therapeutic strategies applied at different fibrosis stages. We compared six treatment strategies: treating all patients regardless of fibrosis stage (TA), treating individual patients with one of four treatments starting at four respective stages of liver fibrosis progression (F1S: withholding treatment at stage F0 and starting treatment from stage F1 or higher, and three successive options, F2S, F3S, and F4S), and administering no antiviral treatment (NoRx).

Splenic non-infarction volume determines a clinically significant hepatic venous pressure gradient response to partial splenic embolization in patients with cirrhosis and hypersplenism.

Background: This study aimed to investigate changes in the hepatic venous pressure gradient (HVPG) by partial splenic embolization (PSE) and to identify the determinants of a clinically meaningful postoperative HVPG reduction.

Methods: Sixty-eight patients with cirrhosis and hypersplenism who underwent PSE at our department between September 2007 and June 2020 were included. The HVPG was evaluated pre- and immediately post-PSE.

Iron-rich Kupffer cells exhibit phenotypic changes during the development of liver fibrosis in NASH.

Although recent evidence suggests the involvement of iron accumulation in the pathogenesis of nonalcoholic steatohepatitis (NASH), the underlying mechanisms remain poorly understood. Previously, we reported a unique histological structure termed "crown-like structure (CLS)," where liver-resident macrophages (Kupffer cells) surround dead hepatocytes, scavenge their debris, and induce inflammation and fibrosis in NASH. In this study, using magnetic column separation, we show that iron-rich Kupffer cells exhibit proinflammatory and profibrotic phenotypic changes during the development of NASH, at least partly, through activation of MiT/TFE transcription factors.

Establishing Efficient Systems through Electronic Medical Records to Promote Intra-hospital Referrals of Hepatitis Virus Carriers to Hepatology Specialists: A Multicenter Questionnaire-based Survey of 1,281 Healthcare Professionals.

Objective Persistent hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are major causative factors of hepatic cirrhosis and hepatocellular carcinoma. However, the development of antiviral treatment has enabled their suppression. Therefore, the early detection and treatment of these infections are important.

Albumin-bilirubin score as a useful predictor of energy malnutrition in patients with hepatocellular carcinoma.

Background & Aims: Chronic liver diseases, including hepatocellular carcinoma (HCC), lead to an imbalance in energy metabolism. The non-protein respiratory quotient (npRQ), which estimates energy malnutrition, can be evaluated using an indirect calorimeter; however, npRQ measurement is limited in routine work. This study aimed to investigate the relationship between the albumin-bilirubin (ALBI) score and npRQ in patients with HCC.

Short-term Effects of Hepatic Arterial Buffer Responses Induced by Partial Splenic Embolization on the Hepatic Function of Patients with Cirrhosis According to the Child-Pugh Classification.

Objective This study primarily aimed to investigate the short-term effects of partial splenic embolization (PSE) on the Child-Pugh score and identify predictive factors for changes in the score caused by PSE. The secondary aim was to analyze changes in various parameters at one month postoperatively using these identified factors. Methods Between September 2007 and December 2019, 118 patients with cirrhosis and hypersplenism underwent PSE at our hospital.

Real-World Clinical Application of 12-Week Sofosbuvir/Velpatasvir Treatment for Decompensated Cirrhotic Patients with Genotype 1 and 2: A Prospective, Multicenter Study.

Introduction: Clinical trials of direct-acting antivirals for patients with decompensated cirrhosis have been conducted, but there is limited information on the medicinal applications in clinical settings. We aimed to evaluate the safety and efficacy of sofosbuvir/velpatasvir for decompensated cirrhotic patients with genotypes 1 and 2 in real-world clinical practice.

Methods: A prospective, multicenter study of 12-week sofosbuvir/velpatasvir was conducted for patients with decompensated cirrhosis at 33 institutions.

Efficacy of hypothermia therapy in patients with acute encephalopathy with biphasic seizures and late reduced diffusion.

Background: Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is characterized by biphasic seizures and impaired consciousness. The efficacy of hypothermia/normothermia therapy in patients with AESD has rarely been reported on.

Methods: We enrolled 15 patients with AESD admitted to Yamaguchi University Hospital and Yamaguchi-ken Saiseikai Shimonoseki General Hospital between 2005 and 2019 and retrospectively evaluated the long-term efficacy of hypothermia therapy compared to that of non-hypothermia therapy.

Early Predictors of Objective Response in Patients with Hepatocellular Carcinoma Undergoing Lenvatinib Treatment.

There are limited reports regarding early predictors of objective response (OR) in patients with hepatocellular carcinoma (HCC) treated with lenvatinib. This retrospective study including 70 patients aimed to investigate the efficacy of hepatic biochemical markers. Changes in tumor marker (alpha-fetoprotein (AFP)/des-gamma-carboxy prothrombin (DCP)) levels and albumin-bilirubin (ALBI) score between the baseline value and that estimated one month after treatment were evaluated.

Novel Liquid Biopsy Test Based on a Sensitive Methylated Assay for Diagnosing Hepatocellular Carcinoma.

Liquid biopsies are not used in practice for hepatocellular carcinoma (HCC). Epi proColon is the first commercial blood-based test for colorectal cancer screening based on methylated DNA testing of the septin 9 gene (). However, Epi proColon has some disadvantages, including the requirement of a large amount of blood and lack of quantitative performance.

Novel Therapeutic Strategy Using Interventional Radiology (IVR) for Hepatitis C Virus (HCV)-Related Decompensated Liver Cirrhosis: A Case Report.

BACKGROUND The appearance of direct acting antivirals (DAAs) has produced a major paradigm shift in hepatitis C virus (HCV) infection treatment, and virus elimination has become possible in most patients. Improvement of the model for end-stage liver disease (MELD) score by elimination of HCV has been reported, but for decompensated liver cirrhosis, it is also important to overcome various complications before antiviral treatment. CASE REPORT A 72-year-old male, who had been treated for HCV-related liver cirrhosis was referred to our hospital for treatment of refractory hepatic encephalopathy.

A novel therapeutic strategy for esophageal varices using endoscopic treatment combined with splenic artery embolization according to the Child-Pugh classification.

Variceal hemorrhage may cause high rebleeding and mortality rates. Preventing the first episode of variceal bleeding is mandatory in patients with high-risk esophageal varices (EV). This study aimed to identify factors that predict the recurrence of EV after endoscopic treatment (ET), and to develop a reasonable therapeutic strategy for EV in cirrhosis.

Effect of body composition on survival benefit of hepatic arterial infusion chemotherapy for advanced hepatocellular carcinoma: A comparison with sorafenib therapy.

Aim: Sorafenib is used as a first-line treatment for advanced hepatocellular carcinoma (HCC). However, hepatic arterial infusion chemotherapy (HAIC) has also gained acceptance, but only in Japan. We explored the role of body composition as a factor affecting the survival benefit of HAIC compared to sorafenib for the treatment of advanced HCC.

Evaluation of the Effects of Cultured Bone Marrow Mesenchymal Stem Cell Infusion on Hepatocarcinogenesis in Hepatocarcinogenic Mice With Liver Cirrhosis.

Objectives: Liver transplantation remains the only curative therapy for decompensated liver cirrhosis. However, it has several limitations, and not all patients can receive liver transplants. Therefore, liver regenerative therapy without liver transplantation is considered necessary.
