Objective: In occupational health activities in Japan, evaluating workers' fitness for work following health checkups is a primary task. Health checkups are used to identify workers at high risk of cerebrovascular and cardiovascular diseases and conduct fit-for-work evaluations. However, identifying high-risk individuals based on a single risk factor may overlook those with multiple risk factors who have a high risk of developing cerebrovascular and cardiovascular diseases.

Purpose: In this study, we aimed to establish a method for predicting the probability of each acute radiation dermatitis (ARD) grade during the head and neck Volumetric Modulated Arc Therapy (VMAT) radiotherapy planning phase based on Bayesian probability.

Methods: The skin dose volume >50 Gy (V), calculated using the treatment planning system, was used as a factor related to skin toxicity. The empirical distribution of each ARD grade relative to V was obtained from the ARD grades of 119 patients (55, 50, and 14 patients with G1, G2, and G3, respectively) determined by head and neck cancer specialists.

Article Synopsis
  • The study explored how inhibitory cortical excitability and motor control are affected in individuals with degenerative cerebellar ataxia (DCA) compared to healthy individuals during ballistic-targeting movements.
  • Sixteen participants were involved, with findings showing that individuals with DCA had a significantly longer cortical silent period (cSP) but no correlation between cSP and ataxia severity.
  • The increased inhibitory activity in the brain may hinder motor control in DCA patients, and the study highlights the need for more research on motor control issues related to DCA, despite the small sample size.

Background: Although patients receiving hemodialysis are more likely to develop metabolic disorders and muscle weakness at an earlier stage than healthy individuals, many older dialysis patients have difficulty establishing exercise habits to prevent these problems. Therefore, we evaluated the use of belt electrode-skeletal muscle electrical stimulation (B-SES), which can stimulate a wider area than conventional electrical muscle stimulation (EMS), to examine its application and safety in older hemodialysis patients as a means to improve lower extremity function without voluntary effort. Methods: This study was a randomized controlled trial (RCT) involving 20 older dialysis patients (>65 years old) with reduced physical activity.

Symptoms of adverse reactions to vaccines evolve over time, but traditional studies have focused only on the frequency and intensity of symptoms. Here, we attempt to extract the dynamic changes in vaccine adverse reaction symptoms as a small number of interpretable components by using non-negative tensor factorization. We recruited healthcare workers who received two doses of the BNT162b2 mRNA COVID-19 vaccine at Chiba University Hospital and collected information on adverse reactions using a smartphone/web-based platform.

Article Synopsis
  • The study investigated how repetitive transcranial magnetic stimulation (rTMS) of the cerebellum affects motor performance during targeting tasks in 22 healthy young adults.
  • Participants completed a wrist manipulation task where they aimed to move a bar to a target as quickly as possible; they underwent either active or sham rTMS after the initial repetitions.
  • Results showed that while the sham rTMS group improved in reaction time and accuracy, the active rTMS group experienced inhibited improvements, suggesting that low-frequency rTMS may disrupt motor learning and highlight the cerebellum's role in motor skill development and error correction.
