In this article we discuss some methodological and ethical challenges we faced when conducting a couple-based study on men's role in contraceptive switching, and how we overcame them. The challenges we discuss include recruiting couples with a range of experiences, ensuring informed consent of participants, maintaining confidentiality within interviews, and participants discussing interview content between interviews. As appropriate, we have drawn on study participants' views of these challenges. We conclude that although couple research poses challenges, they can be overcome or minimized, and that for certain research questions this methodology is well worth using.

Evaluation of a Deep Learning Denoising Algorithm for Dose Reduction in Whole-Body Photon-Counting CT Imaging: A Cadaveric Study.
Acad Radiol

Department of Radiology, University Hospital Tuebingen, Hoppe-Seyler-Str. 3, 72076 Tuebingen, Germany (R.D., J.M.B., B.S., J.M., S.G., P.K., S.W., J.H., K.N., S.A., A.B.).
Rationale And Objectives: Photon Counting CT (PCCT) offers advanced imaging capabilities with potential for substantial radiation dose reduction; however, achieving this without compromising image quality remains a challenge due to increased noise at lower doses. This study aims to evaluate the effectiveness of a deep learning (DL)-based denoising algorithm in maintaining diagnostic image quality in whole-body PCCT imaging at reduced radiation levels, using real intraindividual cadaveric scans.
Materials And Methods: Twenty-four cadaveric human bodies underwent whole-body CT scans on a PCCT scanner (NAEOTOM Alpha, Siemens Healthineers) at four different dose levels (100%, 50%, 25%, and 10% mAs).
ESMO Global Consortium Study on the availability, out-of-pocket costs, and accessibility of cancer medicines: 2023 update.
Ann Oncol
January 2025
Department of Medical Oncology, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.
Background: The availability and affordability of safe, effective cancer therapies are core requirements for effective cancer control. Global disparities exist in access, however, yielding unequal cancer outcomes. The goal of this study was to provide updated data regarding the formulary availability, out-of-pocket costs, and accessibility of cancer medicines in countries across the full spectrum of economic development areas.

Bilateral anophthalmia, a clinical condition characterized by the absence of globe and ocular tissues from both the orbits, presents considerable challenges to a patient's daily routine and use of prostheses. The patient's inability to orientate custom ocular prostheses (COPs) 3-dimensionally is understandable, and they typically rely on caregivers to manage the prostheses and prevent inadvertent injury to the socket. This clinical report describes the successful integration of braille script into COPs as a solution to these challenges by improving prosthesis management, decreasing caregiver dependence, and encouraging independence.
