Enriched iron metabolic features such as high transferrin receptor (TfR) expression and high iron content are commonly observed in aggressive gliomas and can be associated with poor clinical responses. However, the underlying question of how iron contributes to tumor aggression remains elusive. Gliomas harboring isocitrate dehydrogenase (IDH) mutations account for a high percentage (> 70 %) of recurrent tumors and cells with an acquired IDH mutation have been reported to have increased motility...

CONCLUSION: Standardizing reference points in commercial TPS and ROIS can bridge infrastructure gaps and improve dose tracking in complex clinical scenarios. This standardization, aligned with AAPM's TG-263, paves the way for continual development of automated, standardized, interoperable tools, enhancing the ease of sharing reference point information.

CONCLUSION: These surrogate strategies have enabled the gating of complex moving targets among different treatment sites at our institution.

The Competency-Based Veterinary Education (CBVE) Analyze Working Group of the American Association of Veterinary Medical Colleges (AAVMC) Council on Outcomes-based Veterinary Education (COVE) has developed a CBVE assessment toolkit. The toolkit is designed to provide curriculum committees and individual instructors with an opportune intersection of the CBVE domains of competence and various assessment techniques. College-wide curriculum committees can use the toolkit to guide programs of...

Diffuse intrinsic pontine gliomas (DIPG) are highly aggressive and treatment-resistant childhood primary brainstem tumors with a median survival of less than one year after diagnosis. The prevailing standard of care for DIPG, radiation therapy, does not prevent fatal disease progression, with most patients succumbing to this disease 3-8 months after completion of radiation therapy. This underscores the urgent need for novel combined-modality approaches for enhancing therapy responses. This study...

CONCLUSIONS: Incorporating VMAT into MRIgART will significantly reduce treatment session times while maintaining equivalent plan quality.

Radiation therapy (RT) is a cornerstone in cancer treatment (used in 50% of cases), yet challenges persist because damage to normal tissue through direct impact of radiation or bystander effects is inevitable. Injury of macrovessels by RT manifests as obstructive disease, which is akin to atherosclerotic disease. Historically observed in coronary arteries of patients treated for breast cancer and lymphoma, it also affects patients receiving contemporary therapy for lung and chest cancers....

Preventing aggression is a global social issue that warrants additional research with up-to-date measures. Aggressive behaviors manifest in several ways, and the proper assessment should capture its multidimensional nature. We developed the Forms and Functions of Aggressive Behavior Scale (FFABS) to capture the field's current multidimensional understanding of aggression, including its forms (physical, verbal, and relational) and functions (proactive and reactive). Across three studies (N =...

Ferroptosis is a form of cell death characterized by a pro-oxidative cellular milieu and iron-dependent lipid peroxidation. Ferroptosis has been implicated in various forms of liver injury, in keeping with the major role of the liver in iron metabolism. Limited research has addressed potential differences in ferroptosis mediators with age and sex, especially in an in vivo model. The goal of this investigation was to evaluate hepatic labile iron and mediators of ferroptosis with ageing in both...

Pneumomediastinum is the presence of gas (usually air) in the mediastinum, which is rare and typically benign. Pneumomediastinum is classified into primary and secondary based on etiology. Its pathophysiology is due to high intra-alveolar pressures causing alveolar rupture, which releases air that travels along bronchoalveolar sheaths into the mediastinum. Pneumomediastinum may also be concurrently seen with pneumorrhachis defined as air in the spinal canal, although this finding is rare. Here,...

CONCLUSIONS: P-AscH^(-) infusions of 75 g three times weekly in patients with metastatic pancreatic cancer prolongs overall and progression free survival without detriment to quality of life or added toxicity (ClinicalTrials.gov number NCT02905578).

Following on from the 2015 Lancet Oncology Commission on expanding global access to radiotherapy, Radiotherapy and theranostics: a Lancet Oncology Commission was created to assess the access and availability of radiotherapy to date and to address the important issue of access to the promising field of theranostics at a global level. A marked disparity in the availability of radiotherapy machines between high-income countries and low-income and middle-income countries (LMICs) has been identified...
