Purpose: This study reports on the current status of Radiation Therapist (RTT) education and training globally. RTTs are the health professionals responsible for the preparation and delivery of courses of radiation therapy, the latter being indicated in the management of 50%-60% of patients with cancer globally. Therefore, high standards of education of these professionals are paramount to safe and high-quality cancer care.

The European Society of Radiotherapy and Oncology (ESTRO) and the International Atomic Energy Agency (IAEA) project on 'best practice in radiation oncology: a project to train the radiation therapist trainers' commenced in 2008. The aim of the project was to influence education programmes throughout, mainly, eastern Europe to increase the radiation therapy-specific education of their programmes. This is to enable graduates of these programmes to be radiation therapists that are fit for purpose in the clinic.

Despite extensive preparedness literature, existing studies fail to adequately explore healthcare graduates' feelings of preparedness longitudinally across new graduate transition journeys, nor do they compare different healthcare professions to ascertain what opportunities exist for multiprofessional transition interventions. Therefore, this Australian study, underpinned by temporal theory, explores the preparedness transitions of medicine and pharmacy graduates. Our 6-month qualitative longitudinal study involved 12 medicine and 7 pharmacy learners after purposive sampling.

Rheumatoid arthritis is a debilitating inflammatory condition which has a high disease burden. While there is emerging evidence that certain foods and diets could have anti-inflammatory properties and there are published 'anti-inflammatory' diets, there is very little understanding of patient beliefs and perceptions about the impact of diet on symptom management or attitudes to particular dietary interventions. This scoping review aims to summarize the existing literature around the beliefs that patients with rheumatoid arthritis hold regarding the impact of diet on disease activity and joint pain.

Advanced practitioners are healthcare professionals that are highly skilled with a particular area of expertise. These roles have been successfully implemented in many healthcare settings, improving efficiency of the service, as well as enhancing the standard of care received by patients. Although advanced practice roles have been implemented in some radiation therapy departments, their implementation have yet to be facilitated in the majority of countries.

Objective: Disease activity monitoring in SLE includes serial measurement of anti-double stranded-DNA (dsDNA) antibodies, but in patients who are persistently anti-dsDNA positive, the utility of repeated measurement is unclear. We investigated the usefulness of serial anti-dsDNA testing in predicting flare in SLE patients who are persistently anti-dsDNA positive.

Methods: Data were analysed from patients in a multinational longitudinal cohort with known anti-dsDNA results from 2013 to 2021.

Article Synopsis
  • The study evaluates an existing CT-based radiomic signature, originally developed for predicting HPV status in oropharyngeal cancer, to see if it can also apply to anal cancer.
  • A dataset consisting of 59 patients was analyzed, and the radiomic model showed an AUC of 0.68 and an F1 score of 0.78, indicating moderate performance in predicting HPV status.
  • The research suggests that this radiomic signature may be a valuable tool for identifying HPV status across different cancer types, highlighting its potential as a CT imaging biomarker.

Introduction: Timely access to radiotherapy innovations remains suboptimal, partly because there is no commonly agreed appraisal system suitable for the broad range of radiotherapy interventions. The Health Economics in Radiation Oncology (HERO) programme of ESTRO therefore engaged in building a radiotherapy-specific value-based framework. We report on a first step towards that aim, documenting the available definitions and classification systems for radiotherapy interventions.

Background/aim: Radiomics involves high throughput extraction of mineable precise quantitative imaging features that serve as non-invasive prognostic or predictive biomarkers. High levels of hypoxia are associated with a poorer prognosis in prostate cancer and limit radiation therapy efficacy. Most patients with prostate cancer undergo magnetic resonance imaging (MRI) as a part of their diagnostics, and T2 imaging is the most utilised imaging method.

Objective: Simultaneous antibody testing during screening for autoimmune conditions is discouraged. The incidence of positive extractable nuclear antigen (ENA) in the setting of a negative antinuclear antibody (ANA) has been reported as low. Our objective was to characterize the frequency of diagnosis of new ANA-associated rheumatic disease (AARD) in the setting of a negative ANA with a positive ENA.

Diversity in research teams ties alternative perspectives into research projects, and this can fast-forward scientific progress. Concerted efforts have been aimed at encouraging and supporting women to pursue a career in science, yet a gender disparity can still be observed at senior positions, with fewer women in leadership roles. To get insight into how the current landscape for women in science is perceived by different career stages, we interviewed female authors of Molecular Oncology from diverse career stages and disciplines about their inspiration, challenges they have faced as scientists as well as their thoughts on how gender diversity can be further enhanced.
