Background: Diabetes mellitus (DM) is linked to complications such as retinopathy, nephropathy, neuropathy, and cardiovascular disease, impacting patient quality of life and increasing healthcare costs. Periodontal disease, more prevalent in diabetic patients, is associated with worsened glycemic control and systemic inflammation, suggesting a possible bidirectional relationship. While some studies indicate periodontal treatment may improve glycemic control and reduce inflammation, overall evidence is inconsistent.

Introduction: The lateral longitudinal arch (LLA) is an essential structure of the foot. However, LLA evaluation methods remain underexplored compared to those of the medial longitudinal arch (MLA). This study sought to develop a method for measuring the cuboid height, the keystone of the LLA, using ultrasonography and to verify its correlation with radiography, as well as intrarater and interrater reliability.

Objective: Burning mouth syndrome (BMS) is characterized by a chronic, ongoing sensation of intraoral burning or discomfort without causative lesions. This study sought to examine the relationship between personality traits in patients with BMS using the Rosenzweig Picture Frustration (PF) study, a projective psychological test, and their progress in treatment.

Methods: Data were collected from outpatients diagnosed with BMS at our clinic between April 2017 and March 2021.

Purpose: This study aimed to investigate the usefulness of a newly developed oral simulator for nursing students' oral assessment education on oral diseases and symptoms.

Materials And Methods: The participants were first-year students (n=105) at a nursing school in Japan. Ten identical oral simulators with angular cheilitis, missing teeth, dental caries, calculus, periodontitis, hypoglossal induration, food debris, and crust formation were created by a team of dentists.

Background: Interprofessional education (IPE) is essential for healthcare students to collaborate effectively in multidisciplinary teams. This study aimed to identify the effect of IPE programmes in nursing care and oral healthcare on dental and nursing students' perceptions of interprofessional collaboration.

Methods: The study included 101 third-year dental and 98 fourth-year nursing students.

Introduction Burning mouth syndrome (BMS) is characterized as chronic burning pain or unpleasant discomfort in the oral region without any corresponding clinical abnormalities. The aim of this study is to investigate the difference in clinical features and the variations of pain expressions between BMS patients with and without psychiatric comorbidities. Methodology The patients with BMS who first visited between April 2016 and March 2020 were involved and the clinical data including the presence of psychiatric comorbidities and scores of self-rating depression scale (SDS), pain catastrophizing scale (PCS), and pain quality from short-form McGill pain questionnaire (SF-MPQ) were collected retrospectively.

Article Synopsis
  • Augmenting T-cell activity is key to improving cancer immunotherapy, and inhibiting the HPK1 kinase can boost cancer immunity by enhancing T-cell receptor signaling.
  • The study introduces DS21150768, a new small-molecule inhibitor of HPK1 that effectively enhances T-cell function and demonstrates strong anti-tumor effects in various mouse cancer models.
  • DS21150768 is orally bioavailable and shows sustained plasma levels, leading to increased immune responses, with promising implications for future HPK1-targeted therapies and understanding tumor characteristics for treatment efficacy.

Aim: In Japan, primary human papilloma virus (HPV) testing has not been introduced for cervical cancer screening due to concerns that HPV-negative lesions may be missed and a lack of Japanese data. The purpose of this study was to evaluate the validity of primary HPV testing in Japan by analyzing cervical intraepithelial neoplasia 2 (CIN2) or more/high-risk HPV- (CIN2+/hrHPV-) cases in cervical cancer screening.

Methods: Data from 35 525 cervical cancer screenings with HPV testing and cervical cytology from 2011 to 2019 in Saga City, Japan, were reviewed.

The first total synthesis of (+)-tanzawaic acid B, a natural polyketide bearing a pentadienoic ester and octalin moiety, has been accomplished. The synthetic improvement from previous synthetic conditions facilitated our gram-scale synthesis of the chiral octalin that possesses seven stereogenic centers and that is the core skeleton of almost all of the tanzawaic acid family.

Objectives: Oral cenesthopathy is an uncomfortable and bizarre oral sensation without corresponding organic findings. Although some treatment options, including antidepressants and antipsychotic drugs, have been reported to be effective, the condition remains refractory. Here, we report a case of oral cenesthopathy treated with brexpiprazole, a recently approved D2 partial agonist.

  • The study investigates the pharmacokinetics and pharmacodynamics (PK/PD) of pazufloxacin, a drug effective against a bacterium associated with hospital infections.
  • The research involves creating a mouse infection model and measuring pazufloxacin levels using high-performance liquid chromatography to establish its effectiveness.
  • Findings suggest that specific AUC/MIC and C/MIC ratios can optimize dosing regimens, which may help prevent the spread of nosocomial infections.

Animals display a body temperature rhythm (BTR). Little is known about the mechanisms by which a rhythmic pattern of BTR is regulated and how body temperature is set at different times of the day. As small ectotherms, Drosophila exhibit a daily temperature preference rhythm (TPR), which generates BTR.

Oral cenesthopathy (OC) is characterized by unusual oral discomfort without corresponding evidence, and it has often been categorized as "delusional disorder, somatic type". Regarding possible causative factors of OC, involvement of neurovascular contact (NVC) of the trigeminal nerve, which transmits not only pain but also thermal, tactile, and pressure sensations, has never been observed yet. This study aimed to investigate the relationship between clinical characteristics of unilateral OC and the presence of trigeminal nerve NVC.

Background: The relationship between oral and cognitive functions among older people is highly debated.

Objective: To examine whether oral functions are related to changes in the levels of mild cognitive impairment (MCI) biomarkers in older Japanese outpatients.

Methods: This observational study included 52 outpatients aged ≥65 years who underwent dental examinations at the Fukuoka Dental College Hospital.

Burning mouth syndrome (BMS) is a common condition of predominant oral pain without evident cause, that maxillofacial surgeons and otolaryngologists often refer to psychiatrists as somatic symptom disorder. In very rare cases, its typical burning symptom mimics those of other diseases in which serious fatal comorbidities may be missed. We encountered three rare cases of oral squamous cell carcinoma (OSCC) with the first symptom of burning tongue.

Background And Aim: Recent shifts in the distribution of Japan's population towards older ages, have meant that the chance of encountering patients with dementia in dental clinics is increasing. Many studies have shown that the brain volume decreases along with the progression of dementia. Although previous studies have reported a relationship between tooth loss or periodontitis and the onset of dementia, the pathological mechanisms underlying this association have not been elucidated.
