Objective: The aim of this study was to analyze the relevance of tumor progression in the interval between surgery and radiation therapy (RT) in patients with glioblastoma and its interaction with the extent of resection.
Methods: In a retrospective cohort study, all patients who underwent resection for glioblastoma, IDH wildtype, at a single institution from January 2011 to February 2023 with early postoperative and additional pre-RT MRI available for analysis were included. Early postoperative MR images were graded according to whether they showed no enhancing or nonenhancing residual tumor (group 1a), no contrast-enhancing but residual nonenhancing tumor (group 1b), or residual contrast-enhancing tumor (group 2).
Xerostomia is a common radiation-associated toxicity in patients with head and neck cancer. Although several studies examined the decrease in saliva production due to radiotherapy (RT) and investigated the factors associated with this side effect, little is known about the change in radiation-associated saliva composition. This systematic review is the first to summarize existing data and give an overview of the change in pH/buffer capacity, electrolytes, proteins, enzymes, and mucins due to radiation to the salivary glands.

Article Synopsis
- This study aimed to identify factors that predict a good response to low-dose radiotherapy (LDRT) in patients suffering from greater trochanteric pain syndrome (GTPS).
- Patients received LDRT at doses of 0.5-1.0 Gy per fraction, and a good response was noted if there was significant pain relief after two months, assessed by the von Pannewitz score.
- Results showed that prior pain relief from steroid injections, receiving two series of LDRT, and not having structural abnormalities significantly increased the chances of a good response to the treatment.
Background: Thermal dose in clinical hyperthermia reported as cumulative equivalent minutes (CEM) at 43 °C (CEM43) and its variants are based on direct thermal cytotoxicity assuming Arrhenius 'break' at 43 °C. An alternative method centered on the actual time-temperature plot during each hyperthermia session and its prognostic feasibility is explored.
Methods And Materials: Patients with bladder cancer treated with weekly deep hyperthermia followed by radiotherapy were evaluated.
Purpose: The aim of this study was to evaluate the utility of automated plaque analysis in differentiating chronic total occlusion (CTO) from subtotal occlusion (SO) in patients with ambiguous coronary lesions on coronary computed tomography angiography (CTA).
Materials And Methods: A total of 63 patients with 63 ambiguous coronary lesions on CTA were included. The lesion length (LL), diameter stenosis, plaque volume and composition, remodeling index, and contrast density difference (CDD) (reflecting intraluminal contrast kinetics over the lesion) were assessed using an automatic software tool.
Objectives: This study aimed to evaluate the diagnostic accuracy of coronary computed tomography angiography (CTA) for detecting coronary artery stenoses in patients with valvular heart disease undergoing valve surgery.
Background: Coronary CTA is currently not routinely recommended for detecting coronary artery stenoses before cardiac valve surgery. However, recent improvements in computed tomography technology may enable the identification of the most appropriate candidates for coronary CTA before valve surgery.
