Background And Purpose: A novel ring-gantry cone-beam computed tomography (CBCT) imaging system shows improved image quality compared to its conventional version, but its effect on autosegmentation is unknown. This study evaluates the impact of this high-performance CBCT on autosegmentation performance, inter-observer variability, contour correction times and delineation confidence, compared to the conventional CBCT.
Materials And Methods: Twenty prostate cancer patients were enrolled in this prospective clinical study.
Background: This study was undertaken to understand the role of the Health Care Assistants and how they negotiate roles and responsibilities with Registered Nurses in adult acute hospitals.
Methods: The qualitative approach of focused ethnography used non-participant observation and interviews with staff from four acute wards. Field notes and interview data, analysed using NVIVO10, moved data from description through explanation, interpretation and identification of themes.
Article Synopsis
- * The study introduces enhanced modeling techniques for neutrino flux and detector response, and it distinguishes between starting (inside) and throughgoing (outside) neutrino interaction events to improve energy resolution.
- * The findings indicate a best-fit point for the 3+1 model with sin²(2θ_{24})=0.16 and Δm_{41}²=3.5 eV², supporting previous studies while showing consistency with no evidence of sterile neutrinos, as reflected
Unlabelled: Administering zoledronic acid (ZA) to older hip fracture patients during the hospital stay has faced safety concerns. However, in this study of 161 patients, no ZA-related side effects or readmissions were observed, demonstrating that ZA administration during hospitalization is safe and effective for secondary fracture prevention.
Purpose: According to the 2022 Dutch 'Osteoporosis and fracture prevention' guideline, zoledronic acid (ZA) is the preferred osteoporosis treatment for hip fracture patients.
Objective: Hypofractionation has become the new clinical standard for prostate cancer. We investigated the management of acute toxicity in patients treated with moderate hypofractionation (MHF) or Ultrahypofractionation (UHF).
Methods: In a prospective cohort setting, patients (N=316) received either MHF (20 fractions of 3/3.
