Purpose: To propose a methodology for integrating the out-of-field and imaging doses to the in-field dose received by radiotherapy (RT) patients. In addition, the impact of considering the total dose in planning and radiation-induced second malignancies (RISM) risk assessment will be evaluated in several scenarios comprising photon and proton treatments.

Methods: The total dose is the voxel-wise sum of the doses from the different radiation sources (accounting for the radiobiological effectiveness) produced during the whole RT chain.

Background: The radiation exposure of nuclear medicine personnel, especially concerning extremity doses, has been a significant focus over the past two decades. This study addresses the evolving practice of NM, particularly with the rise of radionuclide therapy and theranostic procedures, which involve a variety of radionuclides such as Ga, Lu, and I. Traditional studies have concentrated on common radioisotopes like Tc, F, and Y, but there is limited data on these radionuclides, which are more and more frequently used.

Article Synopsis
  • Drug-induced long QT syndrome (diLQTS) is a serious side effect of over 150 medications that can lead to dangerous heart conditions; the study aimed to validate a genetic risk score for predicting this syndrome.
  • Researchers analyzed data from a large cohort of patients taking high-risk QT-prolonging drugs and found that the risk score was significantly associated with diLQTS in White patients, indicating a higher likelihood of QT prolongation during treatment.
  • Although the risk score showed promise in identifying high-risk individuals, the study was underpowered to confirm its effectiveness across African American and Asian populations, highlighting the need for larger sample sizes in diverse groups.

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

To ensure the continued advancement of the medical physics profession, the European Federation of Organisations for Medical Physics (EFOMP) has designed a mentorship programme. This programme aims to support Early Career Medical Physicists by providing them with the guidance needed for both professional and personal development to meet the continually evolving demands of the medical physics field within their working environments. The EFOMP mentorship programme is an important step forward in supporting the next generation of medical physicists.
