Symptom occurrence impacts primary brain tumor patients from the time of diagnosis and often heralds recurrence. In addition, the therapy can also result in symptoms that may compound tumor-associated symptoms, further impacting the patient's function and overall quality of life. There is increasing recognition that clinical studies evaluating tumor response using only measures of tumor size on imaging or survival are inadequate in brain tumor patients. Many symptoms can only be assessed from the patient, and patient reported outcome measures have been developed and have adequate reliability and validity. These measures are beginning to be incorporated into clinical trials. Guidelines on their use and meaning are needed to standardize assessment across trials and facilitate measurement of clinical benefit.

Waste expectations of fusion steels under current waste repository criteria

G. W. Bailey, O. V. Vilkhivskaya, M. R. Gilbert

Summary: Studies have shown that during operation of fusion reactors, steels will become activated and need to be disposed of as radioactive waste. The waste expectations of steels from European DEMO-like fusion reactors were investigated, revealing that some steels may struggle to meet low level waste requirements. It is recommended that waste disposal strategies are included in fusion reactor proposals before construction begins to align with radioactive waste regulations.

Using first-principles calculations to predict the mechanical properties of transmuting tungsten under first wall fusion power-plant conditions

Yichen Qian, Mark R. Gilbert, Lucile Dezerald, David Cereceda

Summary: Tungsten and tungsten alloys are considered as leading materials for future fusion energy devices due to their high melting point, thermal conductivity, and low radioactive footprint. However, the low fracture toughness of tungsten limits its applications. Significant neutron-induced transmutation occurs in tungsten components during nuclear fusion reactions, necessitating the use of density functional theory calculations to better understand their behavior.

Summary: Predicting material performance in fusion reactor environments relies on computational modeling supported by experiments. Leading experts discussed current positions and ongoing challenges in modeling fusion materials, highlighting topics such as irradiation-induced defect production, gas behavior, clustering, and defect evolution.

Clinical trial challenges, design considerations, and outcome measures in rare CNS tumors

Terri S. Armstrong, Mark R. Gilbert

Summary: Clinical research for patients with rare cancers is challenging due to difficulties in patient accrual, trial design, and evaluation of treatment outcomes. Despite these challenges, studies on rare cancers have yielded important findings, emphasizing the importance of incorporating patient outcomes measures in future trials.

Summary: The latest results from experimental activities conducted within the 'ACT' sub-project under the EUROfusion WPJET3 programme on irradiating ITER materials are presented, including analyses of various material samples and characterization of irradiation locations. These results also include comparisons with neutron transport and activation calculation predictions for the ITER samples.

Macroscopic elastic stress and strain produced by irradiation

Luca Reali, Max Boleininger, Mark R. Gilbert, Sergei L. Dudarev

Summary: In this study, we propose a method for computing macroscopic elastic stress and strain in components of a fusion power plant using the eigenstrain produced by defects in a material exposed to high energy neutron irradiation. Analytical and numerical analysis of several case studies related to the design of a fusion power plant show that the spatial distribution of defects leads to significant elastic stresses in ion-irradiated thin films, pressurized cylindrical tubes, and breeding blanket modules.

Tumor Mutation Burden, Expressed Neoantigens and the Immune Microenvironment in Diffuse Gliomas

Guangyang Yu, Ying Pang, Mythili Merchant, Chimene Kesserwan, Vineela Gangalapudi, Abdalla Abdelmaksoud, Alice Ranjan, Olga Kim, Jun S. Wei, Hsien-Chao Chou, Xinyu Wen, Sivasish Sindiri, Young K. Song, Liqiang Xi, Rosandra N. Kaplan, Terri S. Armstrong, Mark R. Gilbert, Kenneth Aldape, Javed Khan, Jing Wu

Summary: The study found that TMB was not correlated with immune score in IDH-mutant gliomas, while in IDH-wildtype tumors, TMB was positively correlated with expressed neoantigens but inversely correlated with immune score. The Antigen Processing and Presentation (APP) score may have potential as a biomarker for immune therapy response in gliomas.

Overview on the management of radioactive waste from fusion facilities: ITER, demonstration machines and power plants

Sehila M. Gonzalez de Vicente, Nicholas A. Smith, Laila El-Guebaly, Sergio Ciattaglia, Luigi Di Pace, Mark Gilbert, Robert Mandoki, Sandrine Rosanvallon, Youji Someya, Kenji Tobita, David Torcy

Summary: In the absence of official standards and guidelines, fusion designers have adopted well-established standards for fission-based nuclear power plants. However, this approach may result in overconservative measures and increased cost and complexity. One important issue in fusion power is the generation of radioactive waste, which is significantly different from fission NPP waste. Fusion waste mainly consists of low-level and intermediate level waste, but without many long-lived isotopes. The use of reduced-activation materials in fusion technology allows for lower decay heat removal and rapid radioactivity decay.

Irradiation damage concurrent challenges with RAFM and ODS steels for fusion reactor first-wall/blanket: a review

Arunodaya Bhattacharya, Steven J. Zinkle, Jean Henry, Samara M. Levine, Philip D. Edmondson, Mark R. Gilbert, Hiroyasu Tanigawa, Charles E. Kessel

Summary: RAFM and ODS steels are the most promising candidates for fusion first-wall/blanket structures, but their performance will deteriorate due to neutron damage and gas effects during operation. Future development should target materials with lower chromium concentration to minimize irradiation-induced effects.

Multilayer interface tracking model of pure tungsten oxidation

Shu Huang, Ryan Kerr, Samuel Murphy, Mark R. Gilbert, Jaime Marian

Summary: A numerical model is presented to predict oxide scale growth on tungsten surfaces under exposure to oxygen at high temperatures, with simulations showing deviations from classical parabolic growth in certain cases. The model is parameterized using experimental measurements and electronic structure calculations, with a comparison to extensive experimental data showing reasonable agreement at most temperatures. This work attempts to embed the thermodynamic and kinetic complexity of tungsten oxide growth into a comprehensive mesoscale kinetic model to fill existing knowledge gaps and guide future tungsten oxidation models.

Summary: Research shows that solid tumor patients experience high levels of psychological distress at diagnosis, but little is known about how this symptom affects disease outcomes. This systematic review explores the link between distress and survival in solid tumor patients, suggesting that psychological distress may impact disease-related outcomes, including survival.

Nuclear data uncertainty propagation and implications for radioactive waste management of fusion steels

Sophia O. von Tiedemann, David M. Collins, Mark R. Gilbert, Ivan A. Kodeli

Summary: Predictions of material activity in commercial fusion conditions mostly rely on computational methods due to lack of data on long-term effects of high-energy neutron irradiation on structural steels. This study focused on modelling neutron activation of four structural steels in a fusion reactor environment after 20 years of operation. Eurofer and F82H steels exhibited higher resistance to neutron activation than G91 and SS316L(N)-IG. The vacuum vessel (SS316L(N)-IG) would not be classified as low-level waste for several centuries.

Summary: Limitations in trial design, accrual, and data reporting hinder efficient and reliable drug evaluation in cancer clinical trials. A semi-automated survey of adult interventional neuro-oncology trials revealed suboptimal trial designs with low randomization rates and overestimation of effect size. Limited results reporting calls for incentives to improve data reporting and harmonization.
