Background: Conflicting data on the effect of the Epstein-Barr virus (EBV) on outcome in Hodgkin's disease (HD) might be due to the heterogeneous nature of this disease. In this study we have investigated whether the effect of EBV status on outcome is different between aetiologically defined age groups (15-34, 35-44, 45+ years) and also between males and females.
Patients And Methods: Paraffin-embedded sections from 273 patients with advanced HD from two related clinical trials were analysed for the presence of EBV using in situ hybridisation.
Results: EBV was detected in 78 (29%) of cases. For all patients, after a median follow-up of 5 years, there were no significant differences in survival by EBV status although there was a trend towards longer failure-free survival times for EBV-positive patients. Multivariate analyses suggested that EBV and sex, when in combination, were prognostic factors for failure-free survival (P = 0.06 for both). For subgroups, the effect of EBV on failure-free survival was significant for males and 15-34 years age group (P = 0.05 and P = 0.03, respectively).
Conclusion: This study suggests that with a median follow-up of 5 years, EBV status does not affect survival but being EBV-positive may be beneficial in terms of failure-free survival, particularly for males and younger adults.

Management and outcome of mesh infection after abdominal wall reconstruction in a tertiary care center.
Hernia
January 2025
Department of Infectious Diseases, Hospices Civils de Lyon, Service des Maladies Infectieuses et Tropicales, 103 Grande Rue de la Croix-Rousse, Lyon, 69004, France.
Purpose: Abdominal wall reconstruction is a common surgical procedure, with a post-operative risk of mesh-associated infection of which management is poorly known. This study aims to comprehensively analyze clinical and microbiological aspects of mesh infection, treatment modalities, and associated outcomes.
Methods: Patients with abdominal mesh infection were included in a retrospective observational cohort (2010-2023).
Highly hypofractionated biaxially rotational dynamic radiation therapy (BROAD-RT) for high-risk prostate cancer.

To report clinical outcomes following highly hypofractionated biaxially rotational dynamic radiation therapy (BROAD-RT), a unique radiation therapy method that facilitates non-coplanar volumetric-modulated arc therapy (VMAT) without the need to rotate the couch or reposition the patient, for high-risk prostate cancer (PCa) with simultaneous integrated boost (SIB) for intra-prostatic dominant lesions (IPDLs), we performed a single-center prospective pilot study. In this study, patients with high-risk PCa according to the D'Amico classification or those with cT3aN0M0 PCa were eligible. VMAT was performed using BROAD-RT, and a dose of 54 Gy in 15 fractions was prescribed for the prostate in combination with SIB for IPDLs at a dose of 57 Gy in 15 fractions.

Prostate-specific membrane antigen (PSMA)-targeted positron emission tomography (PET) has improved localization of prostate cancer (PC) lesions in biochemical recurrence (BCR) for salvage radiotherapy (SRT). We conducted a retrospective review of patients undergoing F-rhPSMA-7 or F-flotufolastat (F-rhPSMA-7.3)-PET-guided SRT compared with conventional-SRT (C-SRT) without PET.

Department of Orthopaedic Surgery, University of Michigan, Ann Arbor, MI, USA.
Background: Geriatric ankle fractures are increasingly common. Previous work has suggested that early weightbearing following ankle fracture fixation is safe in nongeriatric patients. However, limited data is available regarding the safety of immediate weightbearing following fixation of geriatric ankle fractures using standard open reduction internal fixation techniques.

Purpose: This study aimed to evaluate the prognostic significance of magnetic resonance imaging (MRI) parameters on biochemical failure-free survival (BFS) in patients diagnosed with intermediate-risk prostate cancer and treated with robotic ultrahypofractionated stereotactic body radiotherapy (SBRT) without androgen deprivation therapy (ADT).
Methods: A retrospective analysis was conducted in patients with intermediate-risk prostate cancer undergoing robotic SBRT delivered in five fractions with a total radiation dose of 35-36.25 Gy.
