Social Life and Communication Skills of School-Age Children with Congenital Hearing Loss Who Received Cochlear Implants at an Advanced Age.

Introduction: Despite improved hearing, children who receive cochlear implants (CIs) at a later age encounter difficulties in adapting to society, exposing them to psychological and social risks. This study contributes to the conceptualisation of preventive interventions in schools to address potential issues so that these children can play a more active role in society.

Methods: A total of 52 children (aged 3-12 years) who received CIs at 30 months of age were assessed using the Asahide-Shiki Social Adaptive skills test, which evaluates children's social skills on four domains: (A) language, (B) everyday life, (C) social life, (D) communication.

Vancomycin-associated acute kidney injury in underweight patients: a propensity score matching analysis.

Purpose: To investigate the effect of being underweight on the incidence of vancomycin-associated acute kidney injury (AKI) using propensity score matching analysis.

Methods: This study is a retrospective analysis of patients who received vancomycin and had their serum concentration measured at Kitasato University Hospital between January 1, 2016 and December 31, 2020. Patients were divided into underweight and non-underweight groups based on body mass index (BMI), and propensity score matching analysis was used to evaluate whether underweight affected the incidence of acute kidney injury.

Identification of Patients Who Require Two-Point Blood Sampling for the Peak and Trough Values Rather Than One-Point Blood Sampling for the Trough Value for the Evaluation of AUC of Vancomycin Using Bayesian Estimation.

Objectives: It is recommended to adjust the dose of vancomycin (VCM) with a target area under the concentration-time curve (AUC) of 400-600 μg·h/mL. Factors that affect the deviation between AUCs are estimated from the trough value alone and the trough and peak values using practical AUC-guided therapeutic drug monitoring (PAT) for vancomycin. In this study, factors that affect AUC were evaluated.

A randomized sham-controlled trial of transcranial and intranasal photobiomodulation in Japanese patients with mild cognitive impairment and mild dementia due to Alzheimer's disease: a protocol.

Introduction: Photobiomodulation (PBM) is a novel strategy for cognitive enhancement by improving brain metabolism and blood flow. It is potentially beneficial for patients with Alzheimer's disease (AD). We present a study protocol for a randomised controlled trial designed to evaluate the efficacy and safety of PBM.

Association of conventional cigarette smoking, heated tobacco product use, and dual use with hearing loss: A working population-based study.

Introduction: Although conventional cigarette smoking has been linked to an increased risk of hearing loss, the association between heated tobacco products (HTPs) and hearing loss is unknown. The objective of this study was to investigate the association between cigarette and HTP use and hearing loss.

Methods: This cross-sectional study examined the data of 7769 employees from five companies (Study I) and 34404 employees from a large company (Study II), all participants in the Japan Epidemiology Collaboration on Occupational Health Study.
