Image-based Re-evaluation of the JCOG0911 Study Focusing on Tumor Volume and Survival, Disease Progression Diagnosis, and Radiomic Prognostication for Newly Diagnosed Glioblastoma.

Purpose: To re-evaluate images recovered from JCOG0911, a randomized phase 2 trial for newly diagnosed glioblastoma (nGBM) conducted by the Japan Clinical Oncology Group (JCOG) Brain Tumor Study Group.

Methods: The correlation between tumor volumes and survival was evaluated, followed by progression-free survival (PFS) analysis by independent central review based on Response Assessment in Neuro-Oncology (RANO) criteria using MRI recovered from 118 nGBM patients enrolled in the JCOG0911 trial. A radiomic analysis was also performed to identify radiomic features predictive of nGBM prognosis.

Prospective randomized trial of antibiotic prophylaxis for percutaneous renal biopsy.

Background: Infection is a rare complication of percutaneous renal biopsy (RB). However, the questionnaire included in the Kidney Biopsy Guidebook 2020 in Japan revealed that antibiotic prophylaxis (AP) was administered at about 60% of hospitals. The objective of this study was to evaluate whether it is possible to omit AP for RB.

Validation of British Society of Gastroenterology guidelines for acute lower gastrointestinal bleeding from 8,956 cases in Japan.

Background And Aims: We sought to validate the British Society of Gastroenterology (BSG) guidelines for acute lower gastrointestinal bleeding (ALGIB).

Methods: We analyzed 8,956 patients with ALGIB in CODE BLUE-J study and categorized them into four groups based on BSG guidelines. Outcomes included 30-day rebleeding, 30-day mortality, blood transfusion, therapeutic intervention, and severe bleeding.

Computed tomography morphological assessments of central airways in interstitial lung abnormalities and idiopathic pulmonary fibrosis.

Background: Little is known about whether central airway morphological changes beyond traction bronchiectasis develop and affect clinical outcomes in patients with idiopathic pulmonary fibrosis (IPF). This study aimed to compare central airway structure comprehensively between patients with IPF, subjects with interstitial lung abnormality (ILA), and those without ILA (control) using computed tomography (CT). We further examined the prognostic impact of IPF-specific CT airway parameters in patients with IPF.

From Coronavirus Disease 2019 to Herpes Simplex Virus Hepatitis: A Case Report of Complications Linked to Immunosuppressive Therapy.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been linked to severe pneumonia and systemic deterioration in humans. When antiviral drugs and antibodies are not available, it is preferable to choose early treatment methods to suppress cytokine storms. While an interleukin-6 receptor antagonist has proven effective in controlling cytokine storms in coronavirus disease 2019 (COVID-19) pneumonia, it can also increase susceptibility to secondary infections, such as herpes simplex virus (HSV).

Surgical Nuances and Predictors of Requirement for Suprameatal Tubercle Removal in Microvascular Decompression for Trigeminal Neuralgia.

 Suprameatal tubercle (SMT), a bony prominence located above the internal acoustic meatus, is reported to impede the microscopic view during microvascular decompression (MVD) for trigeminal neuralgia (TN). For an enlarged SMT, removal of the SMT may be required in addition to the routine MVD to precisely localize the offending vessels. The objective of this study is to investigate the predictive factors influencing the requirement of SMT removal during trigeminal MVD.

Prescription trends in Japanese advanced Parkinson's disease patients with non-motor symptoms: J-FIRST.

Background: Non-motor symptoms (NMS) are important factors when selecting treatments for patients with advanced Parkinson's disease (PD). We sought to elucidate the prescribing practices for advanced PD patients with NMS in Japanese clinical practice.

Methods: We examined the prescription rates and doses of anti-PD drugs, and the use of non-steroidal anti-inflammatory drugs (NSAIDs) in post hoc analyses of a 52-week observational study of 996 PD patients with wearing-off on levodopa-containing therapy and ≥1 NMS.

Development of a new antibody drug to treat congenital tooth agenesis.

Background: This study aimed to develop a therapeutic agent promoting teeth regeneration from autologous tissues for congenital tooth agenesis, specifically for hypodontia (≤5 missing congenital teeth, 10% prevalence) and oligodontia (≥6 missing congenital teeth, 0.1% prevalence).

Highlight: We studied mice genetically deficient in the USAG-1 protein, an antagonist of BMP/Wnt which forms excessive teeth.

Clinical outcomes of peripherally inserted central catheters in patients with gastroenterological diseases: Report of a 9-year experience.

Background: Peripherally inserted central catheters (PICCs) are safe and useful alternatives to centrally inserted central catheters (CICCs). Several studies have investigated the effectiveness and safety of PICCs; however, few have focused on their use in patients with gastroenterological diseases. In the present study, we evaluated the outcomes of patients with gastroenterological diseases who received PICCs and identified the risk factors associated with central line-associated blood stream infection (CLABSI).
