Next Generation RNA/Protein-Carrying Vector With Pleiotropic Activity.

Human parainfluenza virus type 2 (hPIV2), one of the causative agents of infantile common cold, is a non-segmented negative-sense RNA virus with a robust gene expression system. It infects recurrently throughout human life without causing severe disease. Because hPIV2 has a viral envelope that can carry ectopic proteins, we developed a non-propagative RNA/protein-carrying vector BC-PIV by deleting the F gene from hPIV2.

Bleomycin-Induced Pulmonary Fibrosis in Transgenic Mice Carrying the Human rs35705950 Variant.

Idiopathic pulmonary fibrosis (IPF) is a progressive, often fatal lung disease characterized by tissue scarring and declining lung function. The promoter polymorphism rs35705950, a significant genetic predisposition for IPF, paradoxically associates with better survival and slower disease progression than other IPF genotypes. This study investigates the potential paradoxical protective effects of this variant in lung fibrosis.

Effect of prior depression diagnosis on bipolar disorder outcomes: A retrospective cohort study using a medical claims database.

Background: Bipolar disorder often emerges from depressive episodes and is initially diagnosed as depression. This study aimed to explore the effects of a prior depression diagnosis on outcomes in patients diagnosed with bipolar disorder.

Methods: This cohort study analyzed data of patients aged 18-64 years who received a new bipolar disorder diagnosis in Japan, using medical claims data from January 2005 to October 2020 provided by JMDC, Inc.

Usefulness of pancreatic volume quantitative analysis as a predictor of development and severity of post-endoscopic retrograde cholangiopancreatography pancreatitis.

Background: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is one of the most common and serious adverse events associated with ERCP. Thus, we aimed to investigate the usefulness of pre-ERCP pancreatic volume, which is deeply involved in exocrine pancreatic function, as a predictor of PEP development and severity.

Methods: In total, 1107 patients who underwent their first ERCP were recruited from January 2012 to December 2022 for this retrospective study.

Programmed Death Ligand 1 Expression in Circulating Tumor Cells as a Predictor and Monitor of Response to Atezolizumab plus Bevacizumab Treatment in Patients with Hepatocellular Carcinoma.

There remains no reliable biomarker of therapeutic efficacy in hepatocellular carcinoma (HCC) for the PD-L1 inhibitor atezolizumab and bevacizumab (Atezo/Bev). Circulating tumor cells (CTCs) enable the serial collection of living tumor cells. Pre-treatment and serial CTC gene expression changes and tumor histology were evaluated to identify predictors of response to Atezo/Bev.

Isolation of mucosa-associated microbiota dysbiosis in the ascending colon in hepatitis C virus post-sustained virologic response cirrhotic patients.

Background: Achieving sustained virologic response (SVR) in patients infected with hepatitis C virus (HCV) reduces all-cause mortality. However, the mechanisms and risk factors for liver fibrosis and portal hypertension post-SVR remain incompletely understood. In the gut-liver axis, mucosa-associated microbiota (MAM) substantially influence immune and metabolic functions, displaying spatial heterogeneity at the anatomical intestinal site.

Functional outcome of a patient after hip disarticulation due to an infection 10 years after limb salvage surgery for osteosarcoma: A case report.

Limb salvage is a common procedure after extensive osteosarcoma resection. However, the long-term outcomes after limb salvage surgery (LSS) remain unclear. In this article, the case of a 24-year-old man who underwent hip disarticulation (HD) after an uncontrollable infection is presented.

High correlation of hepatic shear wave velocity with esophageal varices complication rate in patients with chronic liver diseases.

Background: Histological evaluation by liver biopsy is considered the gold standard for assessing liver disease; however, it is highly invasive. Non-invasive liver stiffness measurement by shear wave elastography (SWE) is effective for evaluating the hepatic fibrosis stage and related diseases. In this study, we investigated the correlations of liver stiffness with hepatic inflammation/fibrosis, functional hepatic reserve, and related diseases in patients with chronic liver disease (CLD).

Longer Survival and Preserved Liver Function after Proton Beam Therapy for Patients with Unresectable Hepatocellular Carcinoma.

Background: Proton beam therapy (PBT) has been recently reported to achieve excellent tumor control with minimal toxicity in patients with unresectable hepatocellular carcinoma (HCC). Radiofrequency ablation (RFA) combined with transcatheter arterial chemoembolization (TACE) was investigated for larger HCC. This study was designed to evaluate the therapeutic effect of PBT on unresectable HCC in comparison with TACE combined with RFA.

Hepatocellular carcinoma progression promoted by 5-lipoxygenase activity in CD163(+) tumor-associated macrophages.

Arachidonic acid 5-lipoxygenase (5-LOX), an enzyme that synthesizes leukotrienes (LTs), is involved in cancer development including proliferation, invasion, metastasis and drug resistance. However, the functional role of 5-LOX in hepatocellular carcinoma (HCC) remains to be elucidated. In this study, we analyzed the contribution of 5-LOX in HCC progression and investigated the potential of targeted therapy.

Histology and cytokine levels in hepatic injury accompanying a case of non-severe COVID-19.

The pathogenesis of liver dysfunction that complicates coronavirus disease 2019 (COVID-19) remains unclear, especially in mild to moderate severity cases. In this case, a novel coronavirus infection was detected by polymerase chain reaction (PCR) in a 76-year-old woman hospitalized after presenting with fever. No other abnormal physical findings were observed, and oxygen administration was not required.

Measurements of Antibacterial Activity of Seed Crude Extracts in Cultivated Rice and Wild Oryza Species.

Seeds are continuously exposed to a wide variety of microorganisms in the soil. In addition, seeds contain large amounts of carbon and nitrogen sources that support initial growth after germination. Thus, seeds in the soil can easily promote microbial growth, and seeds are susceptible to decay.

Cholesterol crystal embolism in multiple organs after transarterial chemoembolization for hepatocellular carcinoma: An autopsy case report.

Rationale: Transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) rarely causes cholesterol crystal embolism (CCE). In our case, the histological findings suggested that the onset of CCE occurred at different time points in different organs.

Patient Concerns: A 72-year-old Japanese woman with HCC underwent TACE.

A rare case of eosinophilic gastritis induced by nivolumab therapy for metastatic melanoma.

Cancer immunotherapy using immune checkpoint inhibitors can cause immune reactions at various sites as a side effect called immune-related adverse events (irAEs). The gastrointestinal tract is susceptible to irAEs, however, the degree and presentation vary considerably from case to case. A 76-year-old woman was diagnosed with anal mucosal melanoma.

Successful early diagnosis of monomorphic epitheliotropic intestinal T-cell lymphoma manifesting as chronic diarrhea and hypokalemia using video capsule endoscopy and double-balloon enteroscopy.

Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), formerly known as enteropathy-associated T-cell lymphoma (EATL) type II, is a rare disease with a poor prognosis that is often diagnosed when patients present with intestinal perforation or obstruction. Our patient, a man in his 60 s, had a 5-month history of persistent watery diarrhea. Upper and lower gastrointestinal endoscopy, abdominal computed tomography (CT), and stool culture results were unremarkable.

Successful treatment of mediastinal pancreatic pseudocyst and pancreatic pleural effusion with endoscopic pancreatic duct drainage: A case report.

An 81-year-old man with chronic pancreatitis was being treated with a protease inhibitor. He developed an acute exacerbation of chronic pancreatitis and dyspnea. Contrast-enhanced computed tomography showed disruption of the main pancreatic duct, a cystic lesion connecting the mediastinum to the main pancreatic duct, and left pleural effusion.

Burden of schizophrenia among Japanese patients: a cross-sectional National Health and Wellness Survey.

Background: Schizophrenia places a great humanistic and financial burden to patients, families, and societies, and the burden is substantially impacted by comorbid conditions. This study aimed to estimate the lifetime prevalence of schizophrenia and to assess the health-related quality of life (HRQoL), work productivity, and indirect cost among schizophrenia patients with and without comorbidities (depressive symptoms, sleep disturbances, and anxiety problems).

Methods: This is a secondary analysis of existing data collected in 2019 from the Japan National Health and Wellness Survey.

Elderly onset congenital hepatic fibrosis with portal hypertension diagnosed after recurrent cholangitis: a case report.

Congenital hepatic fibrosis is a rare autosomal recessive disorder caused by ductal plate malformation that can manifest as hepatic fibrosis alone or as a component in various fibropolycystic diseases including renal involvement. It is often diagnosed early in life, presenting with ascites and esophageal variceal bleeding due to non-cirrhotic portal hypertension. Here, we report a rare case of congenital hepatic fibrosis with portal hypertension diagnosed at an advanced age.
