• Radiation-specific Automated Dosimetric dental, Mandible, and maxilla Annotation for Predicting Periodontal Problems (RADMAP): A semi-automated tool for dosimetric oral risk communication and osteoradionecrosis assessment

  medRxiv · 2025-11-25

  preprintOpen access

  Purpose/Objectives: Osteoradionecrosis of the jaw (ORN) is a severe complication of head and neck cancer (HNC) radiotherapy (RT), significantly impacting patient quality of life. Current dose assessment relies on whole-mandible dosimetry, limiting personalized, tooth-specific region risk evaluation. The lack of standardized methods to document and analyze dose distributions to tooth-bearing regions further hampers dental and maxillofacial decision-making. This study develops and evaluates RADMAP, a (semi-)automated tool for segmenting tooth-based jaw regions, enabling patient- and tooth-specific radiation dose mapping to improve dental dose reporting and ORN risk assessment. Methods and Materials: A total of 736 tooth locations from 23 HNC patients treated with definitive RT were analyzed, including 11 who developed ORN. The RADMAP tool applies an angular ray-based algorithm to automatically segment the mandible and maxilla into 32 tooth-specific jaw regions, with optional manual refinement (semi-automated), outputting radiation dose mapping in both tabular and odontogram formats. Mean dose values from manually contoured tooth roots were compared with RADMAP-segmented alveolar regions (fully and semi-automated). Interobserver agreement among six users was evaluated. Whole-mandible, manual tooth, and tooth-based jaw segment (alveolar and basal) doses were compared between regions with and without ORN development. Results: = 0.98, p<0.0001), demonstrating accurate dose estimation. Interobserver agreement showed 95% limits of ±2.9 Gy for mandibular alveolar segments, confirming reproducibility. Tooth-based jaw segments showed a significant differentiation in radiation dose for the ORN-positive versus ORN-negative sites (difference in mean dose (DIM): 12.4 ±3.7 Gy, p=0.0008), which was not seen when considering the whole-mandible dose (DIM=6.2 ±4.3 Gy, p=0.17), demonstrating RADMAP's promise for improved ORN risk assessment. Conclusion: RADMAP enables accurate, tooth-specific dose mapping of the mandible and maxilla, and potential improved ORN risk differentiation beyond whole-mandible dosimetry. Tooth-based dose reporting can personalize treatment, enhance multidisciplinary communication, and support prevention of radiation-related orodental sequelae.

• Nationwide implementation of the international multidisciplinary best-practice for locally advanced pancreatic cancer (PREOPANC-4): study protocol

  BMC Cancer · 2025-02-19 · 3 citations

  articleOpen access

  BACKGROUND: The introduction of (m)FOLFIRINOX and gemcitabine-nab-paclitaxel has changed the perspective for patients with locally advanced pancreatic cancer (LAPC). Consequently, in experienced centres 23% of patients with LAPC undergo a resection with 5-year overall survival (OS) rates of up to 25%. In the Netherlands, the nationwide resection rate for LAPC remains low at 8%. The PREOPANC-4 program aims for a nationwide implementation of the international multidisciplinary best-practice to improve patient outcome. METHODS: Nationwide program implementing the international multidisciplinary best-practice for LAPC. In the training phase, multidisciplinary and surgical webinars are given by 4 international experts, leading to a clinical protocol, followed by surgical off-site and on-site proctoring sessions. In the implementation phase, the clinical protocol will be implemented in all centres, including a nationwide expert panel (2022-2024). Healthcare professionals will be trained in shared decision-making. Consecutive patients diagnosed with pathology-proven LAPC (i.e., arterial involvement > 90° and/or portomesenteric venous > 270° involvement or occlusion [DPCG criteria]) are eligible. Primary outcomes are median and 5-year OS from diagnosis, resection rate, in-hospital/30-day mortality and major morbidity (i.e., Clavien-Dindo grade ≥ IIIa), and radical resection (R0) rate. Secondary outcomes include quality of life, functioning, side effects, and patients' healthcare satisfaction in all included patients. Outcomes will be compared with patients with borderline resectable pancreatic cancer (BRPC) treated with neoadjuvant FOLFIRINOX in the PREOPANC-2 trial (EudraCT: 2017-002036-17) and a historical cohort of patients with LAPC from the PACAP registry (NCT03513705). The existing prospective LAPC Registry and PACAP PROMs (NCT03513705) will be used for data collection. In qualitative interviews, treatment preferences, values, and experiences of LAPC patients, their relatives, and healthcare professionals will be assessed for the development of shared decision-making supportive tools. It is hypothesized that the program will double the nationwide LAPC resection rate to 16% with major morbidity < 50% and mortality ≤ 5%, and OS following resection similar to that observed in patients with BRPC. DISCUSSION: The PREOPANC-4 program aims to safely implement the international multidisciplinary best-practice for LAPC leading to benchmark outcomes for both short-term morbidity, mortality, and OS. TRIAL REGISTRATION: PREOPANC-4 program was registered at ClinicalTrials.gov (NCT05524090) on September 1, 2022.

• Credibility and influence in health messaging: examining medical professionals' role on X in promoting N95 respirators during COVID-19

  Information Communication & Society · 2025-05-15

  articleOpen access

  This study explores the role of health influencers on X (formerly Twitter) in promoting N95 respirators, with a focus on the accuracy and completeness of the information shared. It evaluates the impact of X influencers on public perception and policy regarding N95 masks. Using a tripartite model integrating eWOM, health messaging, and opinion leadership, the research analyzed 251,740 tweets through social network analysis (SNA) and content analysis. A systematic random sample of 21,436 tweets reveals that influencers with +100k followers and verified accounts achieved higher engagement. While health influencers played a significant role in shaping public understanding, gaps in detailed guidance highlight the need for actionable and precise messaging. Positioned at the intersection of public policy and marketing, our study emphasizes influencer collaboration and standardized communication strategies to improve health information dissemination on digital media.

• The Hidden Players: An Egocentric-Network Analysis of Work–Life Balance Among College Athletics Employees

  Journal of Sport Management · 2025-04-21

  article

  Many employees are reevaluating the role of work in their lives and placing greater emphasis on social activities (e.g., family and leisure time). Simultaneously, the college sport world has witnessed a mass exodus, with many employees leaving to work in other realms. As such, college athletic departments that are struggling to recruit and maintain talented employees would be wise to consider their approach to work–life balance (WLB). Scholars specializing in WLB have begun to emphasize its social nature; WLB is not achieved in isolation but through a process of shared, mutually negotiated role responsibilities. In college sport, however, little is known about employees’ social structures (i.e., their social networks) and how the characteristics of such structures contribute to (or inhibit) WLB. To this end, we leveraged hierarchical linear modeling to conduct an egocentric-network analysis of National Collegiate Athletic Association Division I college sport employees. Our results highlight the dramatic role of others (i.e., “hidden players”), namely, family members and close friends, in helping college sport employees achieve WLB.

• Radiation medicine at a crossroads: a historical perspective to consider future directions

  The Royal College of Radiologists Open · 2025-01-01

  articleOpen access1st authorCorresponding

  Abstract As the world shut down in reaction to the COVID-19 pandemic in April 2020, many radiation oncologists began collaborating to revive a decades-old use of ionizing radiation therapy as a potential treatment for COVID-19 pneumonia. The concept of using low dose radiotherapy (LDRT) for a non-malignant disease based upon historical data proved to be highly controversial, but this debate has revived questions about the role of radiation therapy in medicine in ways that deserve deeper consideration .The aim of this paper is to provide some historical and scientific perspective on perceptions of radiation therapy and its risks, including questioning the linear no threshold (LNT) hypothesis and the emergence of data on radiation hormesis. The hope is that this review will stimulate debate on whether to expand the use of low dose radiotherapy (LDRT) beyond its current use primarily for neoplastic disease. Areas of interest include the potential roles of LDRT in the management of neurodegenerative, neuroinflammatory and autoimmune disease, and acute spinal cord injury.
