Performing biopsies in only MRI positive increased sensitivity of GS ≥ 3 + 4 PC (RS = 1.30; 95% CI = 1.04 to 1.67), reduced number of biopsy procedures by 49.3% while missing 7.2% GS ≥ 3 + 4 PC and 1.4% csPCa. Excluding men with negative Stockholm3 test reduced number of MRI investigations at follow-up by 22.5%, biopsies by 56.8% while missing 6.9% GS ≥ 3 + 4 PC and 1.3% csPCa. During AS, including MRI and targeted/systematic biopsies increase sensitivity of PC reclassification. Incorporation of risk prediction models including biomarkers may reduce the need for MRI use in men with low risk PC.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening condition of immune dysregulation. Children often suffer from primary genetic forms of HLH, which can be triggered by infection. Others suffer from secondary HLH as a complication of infection, malignancy, or rheumatologic disease. Identifying the exact cause of HLH is crucial, as definitive treatment for primary disease is hematopoietic stem cell transplant. Adenoviruses have been associated with HLH but molecular epidemiology data are lacking. We describe the clinical and virologic characteristics of 5 children admitted with adenovirus infection during 2018-2019 who developed HLH or HLH-like illness. Detailed virologic studies, including virus isolation and comprehensive molecular typing were performed. All patients recovered; clinical management varied but included immunomodulating and antiviral therapies. A genetic predisposition for HLH was not identified in any patient. Adenovirus isolates were recovered from 4/5 cases; all were identipredisposition to HLH. These findings suggest that adenovirus 7 infection a
