Article Synopsis
- Dynamic conformal arc therapy (DCAT) and volumetric modulated arc therapy (VMAT) both provide similar quality for treating brain metastases, but this study focused on how MLC errors during treatment affect dose distribution.
- Researchers created reference plans and simulated MLC errors using a head phantom, analyzing how these errors influenced dose delivery to the targets and surrounding brain tissue.
- The findings revealed that while MLC errors affected both techniques' dose distribution similarly, the DCAT technique showed greater resilience, with less variation in target doses compared to VMAT.
Article Synopsis
- A smart insole wearable sensor was developed to assess the effects of different types of insoles on gait and foot comfort for patients with flatfoot.
- Thirty-three participants with flatfoot tested three insole types: a control, a flat cushioning insole, and an arch support insole, measuring gait parameters and foot comfort during walking.
- Results showed that arch support insoles improved foot comfort and altered gait parameters, particularly highlighting foot lift height as important for comfort while walking.
Objectives: Physiological myocardial F-fluorodeoxyglucose (F-FDG) uptake in oncologic positron emission tomography (PET)/computed tomography (CT) is commonly observed with multiple variations under clinical fasting conditions. The purpose of the present study was to evaluate physiological myocardial F-FDG uptake pattern by comparing with the results in cardiac sarcoidosis.
Methods: A total of 174 examinations in 174 patients without cardiac disease and 27 examinations in 17 patients with cardiac sarcoidosis were performed.
Measurements of neutrino oscillation parameters from the T2K experiment using protons on target.

Article Synopsis
- - The T2K experiment reports enhanced measurements of neutrino oscillation parameters through new proton-on-target (POT) neutrino data, significantly improving analysis methods with a major focus on the near detector's new selection procedures.
- - This analysis is the first to utilize data from the NA61/SHINE experiment, helping to refine the neutrino flux model and enhance the neutrino interaction model by incorporating new nuclear effects.
- - Both frequentist and Bayesian approaches indicate a preference for normal mass ordering and a nearly maximal CP-violating phase, with notable exclusions and constraints on certain parameters aligning with past T2K studies.
Favorable short-term results of transfibular total ankle arthroplasty have been reported in several studies; however, the factors affecting these results have not been elucidated. This study aimed to determine whether preoperative depression affects the outcome of transfibular total ankle arthroplasty and whether depression changes with surgery. Scores from the Japanese Society of Surgery of the Foot Ankle/Hindfoot scale (JSSF scale), Self-Administered Foot Evaluation Questionnaire (SAFE-Q), Hospital Anxiety and Depression Scale (HADS), and Timed Up & Go test (TUG) were collected preoperatively, at 6 months, and at 1 year postoperatively from 20 patients.
