Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).

The applause sign (AS) is a recognized phenomenon observed in progressive supranuclear palsy (PSP) and other neurological conditions where individuals produce over three claps following a request to clap only thrice after a demonstration. In this study, we introduced a novel linguistic phenomenon termed the oral applause sign (OAS) associated with the AS. The OAS is characterized by increased repetition counts of Japanese repetitive onomatopoeic words, such as uttering "pata-pata-pata" instead of the expected "pata-pata.

Acute epidural hematoma is one of the most serious traumatic conditions in neurosurgery, for which emergency surgery may be indicated. Injury to the middle meningeal artery (MMA) is generally the cause of hemorrhage, often accompanied by convexity fractures resulting from head trauma. However, an epidural hematoma by a contusion of the jaw is very rare.

Constitutional indocyanine green (ICG) excretion defect (CIED) is a rare clinical condition characterized by markedly delayed ICG disappearance with other normal liver function tests. Here, we report a case of CIED in which laparoscopic anatomical liver resection was successfully performed using ICG fluorescence staining. A 64-year-old man with a 4-cm tumor located in the liver segment 5 was referred to our hospital.

Intravesical instillation of chemotherapy has been performed to reduce the risk of intravesical recurrence of bladder cancer. However, its antitumor effect is not necessarily sufficient, which may be partially due to inadequate delivery of intravesically administered chemotherapeutic agents to bladder tumors. Ultrasound irradiation to target tissues in the presence of microbubbles is a technique to transiently enhance cell membrane permeability and achieve efficient drug delivery to the desired sites without damage to non-target areas; this technique has been used in chemotherapy, immunotherapy, gene therapy, and radiotherapy for the treatment of various cancers.

Follicular lymphoma (FL) may undergo histological transformation (HT) into a more aggressive lymphoma. Although rituximab for B-cell non-Hodgkin lymphomas (B-NHL) has greatly improved the overall survival (OS) of patients with transformed FL (tFL), relapse after anthracycline-based chemoimmunotherapy has a poor prognosis. CD19-targeting chimeric antigen receptor-modified T-cell (CAR-T) therapy is a promising treatment for relapsed or refractory (r/r) large B-cell lymphoma (LBCL), including tFL.

Mesenchymal stromal/stem cells (MSCs) are promising candidates for regenerative medicine owing to their self-renewal properties, multilineage differentiation, immunomodulatory effects, and angiogenic potential. MSC spheroids fabricated by 3D culture have recently shown enhanced therapeutic potential. MSC spheroids create a specialized niche with tight cell-cell and cell-extracellular matrix interactions, optimizing their cellular function by mimicking the in vivo environment.

Background: Disproportionately enlarged subarachnoid space hydrocephalus (DESH) is one of the neuroradiological characteristics of idiopathic normal pressure hydrocephalus (iNPH), which makes statistical analyses of brain images difficult. This study aimed to develop and validate methods of accurate brain segmentation and spatial normalisation in patients with DESH by using the Computational Anatomy Toolbox (CAT12).
Methods: Two hundred ninety-eight iNPH patients with DESH and 25 healthy controls (HCs) who underwent cranial MRI were enrolled in this study.

Background: Flow diverters (FDs) have been introduced for the management of large or giant cavernous carotid aneurysms (CCAs) in addition to conventional modalities, dramatically changing treatment strategies. The aim of this study was to examine the management of unruptured large/giant CCAs in Japan when FDs were being introduced using a nationwide survey.
Methods: 540 unruptured large/giant CCAs treated at neurosurgical teaching departments in Japan between 2012 and 2016 were retrospectively studied.

Background: Identification of predictive biomarkers is crucial for formulating preventive interventions and halting the progression of atopic march. Although controversial, the use of accessible markers to predict or detect early onset of atopic diseases is highly desirable. Therefore, this study aimed to investigate whether corneal squamous cell carcinoma antigen-1 (SCCA1) collected from infants can predict the development of atopic dermatitis and food allergy.

Background: Lung cancer surgery is associated with a high incidence of chronic postsurgical pain (CPSP), which necessitates long-term analgesic prescriptions. However, while essential for managing pain, these have shown various adverse effects. Current guidelines recommend using peripheral nerve blocks over epidural anaesthesia for perioperative analgesia in minimally invasive thoracic surgery (MITS).

The National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) is a database that stores anonymized information on medical receipts and health checkups in Japan. The NDB Open Data is a publicly accessible summary table of the NDB database. To reveal annual trends and regional disparities in radiotherapy utilization in Japan, we analyzed the NDB Open Data tables for a 9-year period from 2014 to 2022.

Objective: This study aimed to explore the social factors of patients and caregivers, including those related to their wishes for home-based end-of-life care that influence its fulfillment.
Methods: A secondary analysis was conducted using the dataset (home-based end-of-life care N = 625, hospital end-of-life care N = 7603) Comprehensive patient-based survey conducted by The Study on Quality Evaluation of Hospice and Palliative Care by Bereaved Caregivers (J-HOPE 4) and multivariate analysis (multiple logistic regression) to explore the impact of social factors of patients and caregivers on the fulfillment of home-based end-of-life care. The explanatory variables included 11 social factors of patients, such as age and sex, and 18 social factors of primary caregivers.

Objectives: The prevalence of dental caries is high in Japan, leading to a huge burden of overall expenditure on dental caries treatment for the population. School-based fluoride mouth-rinse (S-FMR) has been implemented as a public health intervention. However, its cost-effectiveness remains unclear, where universal health insurance covers a broad range of dental treatments at relatively low cost.

The first, second, and third editions were published in 2009, 2013, and 2019, respectively, and the 2023 edition was recently developed. In the development of the 2023 edition, 60 clinical questions (CQs) were listed.

Little is known about how blood free amino acids (FAAs) change in metabolic dysfunction-associated steatotic liver disease (MASLD). This study aims to identify the imbalance of FAAs in MASLD and explore its correction as a potential therapeutic target. We analyzed plasma FAAs data from 23,036 individuals with steatosis information from a biobank in Japan, and 310 patients with MASLD were enrolled.

In esophageal squamous cell carcinoma, genetic activation of NRF2 increases resistance to chemotherapy and radiotherapy, which results in a significantly worse prognosis for patients. Therefore NRF2-activated cancers create an urgent clinical need to identify new therapeutic options. In this context, we previously identified the geldanamycin family of HSP90 inhibitors, which includes 17DMAG, to be synthetic lethal with NRF2 activity.
