Association of Age and Neurological Severity at Intensive Care Unit Admission With Driving Resumption Within 30 Days of Stroke: A Single-Center Historical Cohort Study.

Objectives Guidelines in several countries recommend against driving soon after a stroke; however, some patients resume driving within one month after onset. This study aimed to examine the relationship between neurological and social background factors at intensive care unit (ICU) admission and resumption of motor vehicle driving within 30 days of the first acute stroke/cerebral hemorrhage. Materials and methods Data were extracted from medical records of a single center linked to the National Cerebral and Cardiovascular Center Administration Office for Stroke Data Bank in Japan.

The inflammatory markers and locoregional pathological results both have an impact on the prognosis of oral squamous cell carcinoma in patients who have undergone neck dissection.

Background: Locoregional surgical pathology, with surgical margins at the primary site and lymph node (LN) metastasis, particularly extranodal extension (ENE), plays an important role in the prognosis of oral squamous cell carcinoma (OSCC). In addition, systemic inflammatory response and nutritional status are associated with poor prognosis.

Purpose: This study aimed to comprehensively assess the effect of inflammatory markers and locoregional factors on the prognosis of patients with OSCC who underwent neck dissection (ND).

Safety and immunogenicity of mRNA-based seasonal influenza vaccines formulated to include multiple A/H3N2 strains with or without the B/Yamagata strain in US adults aged 50-75 years: a phase 1/2, open-label, randomised trial.

Background: Inclusion of additional influenza A/H3N2 strains in seasonal influenza vaccines could expand coverage against multiple, antigenically distinct, cocirculating A/H3N2 clades and potentially replace the no longer circulating B/Yamagata strain. We aimed to evaluate the safety and immunogenicity of three next-generation seasonal influenza mRNA vaccines with different compositions that encode for haemagglutinins of multiple A/H3N2 strains, with or without the B/Yamagata strain, in adults.

Methods: This randomised, open-label, phase 1/2 trial enrolled healthy adults aged 50-75 years across 22 sites in the USA.

Association between Timing of Vascular Access Creation and Mortality in Patients Initiating Hemodialysis: A Nationwide Cohort Study in Japan.

Introduction: The optimal time for vascular access (VA) creation remains controversial.

Methods: We conducted a cohort study using data from the Japanese Society for Dialysis Therapy Renal Data Registry. Adult patients who started receiving hemodialysis in 2007 and had a permanent VA created were included.

TB-related technical enquiries received at the Research Institute of Tuberculosis, Japan, during COVID-19.

Setting: Japan: a low-TB-burden country.

Objective: To characterise TB-related technical enquiries received in 2020-2022, and share the lessons learnt.

Design: This was a descriptive study.

Antigenic analysis of the influenza B virus hemagglutinin protein.

Influenza B viruses (IBVs) primarily infect humans and are a common cause of respiratory infections in humans. Here, to systematically analyze the antigenicity of the IBVs Hemagglutinin (HA) protein, 31 ​B/Victoria and 19 ​B/Yamagata representative circulating strains were selected from Global Initiative of Sharing All Influenza Data (GISAID), and pseudotyped viruses were constructed with the vesicular stomatitis virus system. Guinea pigs were immunized with three doses of vaccines (one dose of DNA vaccines following two doses of pseudotyped virus vaccines) of the seven IBV vaccine strains, and neutralizing antibodies against the pseudotyped viruses were tested.

Estimation of Hearing Thresholds with Auditory Steady-State Responses to Narrow-Band Chirps in Children.

Objective: The aim of this study was to evaluate the utility of auditory steady-state responses (ASSRs) to narrow-band chirps (NB-chirps) for estimating hearing levels in children.

Design: Thresholds from the NB-chirp ASSR were evaluated in 30 sedated children with normal hearing or hearing loss. The correlation between the NB-chirp ASSR and pure-tone audiometry (PTA) thresholds was analyzed, and the difference score (DS) between these thresholds was calculated.

Poly(A) Tail Length of Messenger RNA Regulates Translational Efficiency of the Mitochondria-Targeting Delivery System.

Mitochondria are essential for cellular functions, such as energy production. Human mitochondrial DNA (mtDNA), encoding 13 distinct genes, two rRNA, and 22 tRNA, is crucial for maintaining vital functions, along with nuclear-encoded mitochondrial proteins. However, mtDNA is prone to somatic mutations due to replication errors and reactive oxygen species exposure.

Health-related quality of life and caregiver burden of pediatric patients with inborn errors of metabolism in Japan using EQ-5D-Y, PedsQL, and J-ZBI.

Purpose: Inborn errors of metabolism (IEM) are known with poor long-term health concerns; however, the health-related quality of life (HRQoL) and the burden placed on families remain unclear. This study investigated the self- and proxy-reported HRQoL of pediatric patients with IEM with or without developmental disabilities and the burden placed on their caregivers.

Methods: Patients with IEM aged 8-15 years and their caregivers were asked to respond to the Pediatric Quality of Life Inventory (PedsQL), EuroQoL five-dimension questionnaire for younger populations (EQ-5D-Y), and Japanese version of the Zarit Caregiver Burden Interview (J-ZBI).

Optimal size of Frozenix for true thoracic aneurysms: is downsizing an option?

Objective: During total arch replacement (TAR) using frozen elephant trunk (FET) technique with Frozenix for true thoracic aortic aneurysm (tTAA), oversized FET tends to be chosen similar to the endovascular devise selection. However, the oversized FET is considered a risk factor for intimal injury. The appropriate size selection of FET remains insufficiently understood.

FoxD1 expression identifies a distinct subset of hepatic stellate cells involved in liver fibrosis.

Hepatic stellate cells (HSCs) are pericytes of the liver responsible for liver fibrosis and cirrhosis, which are the end stages of chronic liver diseases. TGF-β activates HSCs, leading to the differentiation of myofibroblasts in the process of liver fibrosis. While the heterogeneity of HSCs is appreciated in the fibrotic liver, it remains elusive which HSC subsets mainly contribute to fibrosis.

Quantification of Gremlin 1 throughout the tumor stroma using whole slide imaging and its clinicopathological significance in gastric cancer.

Gremlin 1 (GREM1) is an antagonist of bone morphogenetic protein (BMP). GREM1 is expressed in the stromal cells of various carcinomas and promotes tumor progression by suppressing BMP signaling. We designed this study to establish an evaluation strategy for GREM1 expression, focusing on the tumor stroma, and to examine its clinicopathological significance in gastric cancer (GC) progression.

Common progenitor origin for Rosai-Dorfman disease and clear cell sarcoma.

Histiocytic neoplasms (HNs) in adults have been reported to be associated with a high prevalence of coexisting haematological and solid malignancies. While a proportion of coexisting HNs and haematological malignancies share identical genetic alterations, the genetic association between HNs and solid malignancies has scarcely been reported. We report a case of Rosai-Dorfman disease (RDD) complicated by coexisting clear cell sarcoma (CCS).

A system to analyze the initiation of random X-chromosome inactivation using time-lapse imaging of single cells.

In female eutherian mammal development, X-chromosome inactivation (XCI) of one of the two X chromosomes is initiated early. Understanding the relationship between the initiation of XCI and cell fate is critical for understanding early female development and requires a system that can monitor XCI in single living cells. Traditional embryonic stem cells (ESCs) used for XCI studies often lose X chromosomes spontaneously during culture and differentiation, making accurate monitoring difficult.

Despite significant efforts to identify metabolic pathways for producing these microbial metabolites, a comprehensive metabolic pathway database for the human gut microbiota is still lacking. Here, we present Enteropathway, a metabolic pathway database that integrates 3269 compounds, 3677 reactions, and 876 modules that were obtained from 1012 manually curated scientific literature.

Clinical target volume design and dose in carbon-ion radiation therapy for sinonasal mucosal melanoma.

Background And Purpose: No guidelines exist for the clinical target volume (CTV) and radiotherapy dose in sinonasal mucosal melanoma (SNMM). Thus, we aimed to determine the carbon-ion radiotherapy (CIRT) CTV and dose for SNMM.

Materials And Methods: In total, 135 patients with SNMM who received CIRT were reviewed.

Minimal influenza virus transmission from touching contaminated face masks: a laboratory study.

The risk of virus transmission via the touching of contaminated masks has long been assumed by infection control teams. Yet, robust evidence to support this belief has been lacking. This risk was investigated in a laboratory setting by measuring the amount of viable influenza virus successfully transferred from artificially contaminated medical (surgical) mask surfaces to a human finger used to swipe their outer surface under various experimental conditions.
