RESUMEN
Importance: In randomized clinical trials (RCTs), magnetic resonance imaging (MRI) before prostate biopsy has been associated with fewer biopsies, decreased detection of Gleason score 6 cancers, and increased detection of Gleason score 7 or higher cancers. Objective: To study whether MRI of the prostate before the decision to biopsy is associated with biopsy frequency and distribution of Gleason score in clinical practice. Design, Setting, and Participants: This is a retrospective, population-based cohort study of men in Jönköping Region, Sweden. Men with prostate-specific antigen (PSA) level measured between November 2011 and 2020 were monitored until January 31, 2021. Men with known prostate cancer were excluded. Data analysis was performed from July to December 2022. Exposures: Data on repeated PSA measures, prostate biopsies, and MRI prostate were extracted from health care records, and cancer characteristics were obtained from The National Prostate Cancer Register. Main Outcomes and Measures: The proportions of men who underwent prostate biopsy and risk of Gleason score 6 or Gleason score 7 or higher cancer and negative biopsy before and after introduction of MRI were calculated. Results: In this cohort study of 23â¯802 men (mean [SD] age, 60.8 [13.6] years) who underwent PSA testing, when the use of MRI increased, fewer biopsies were performed (adjusted odds ratio [OR], 0.84; 95% CI, 0.72-0.97) and the odds of detecting Gleason score 6 cancer decreased (OR, 0.47; 95% CI, 0.33-0.64), whereas the odds of detecting Gleason score 7 or higher cancer increased (OR, 1.24; 95% CI, 1.02-1.50). Conclusions and Relevance: In this study, the introduction of MRI to clinical practice was associated with a decreased proportion of men who underwent a biopsy and decreased detection of Gleason score 6 cancer but increased detection of Gleason score 7 or higher cancer. These clinical data support the use of prostate MRI before biopsy in an effort to avoid unnecessary biopsies.

With the aim to improve the outcomes for spinal cord-injured patients undergoing surgery for pressure ulcers, a structured treatment programme regulating pre- and postoperative care and rehabilitation was introduced in 2002 in Stockholm. Fifty-one consecutive patients operated on between 2002 and 2007 were included in a 10-year follow-up to evaluate the programme regarding initial healing results and long-term ulcer and health status. At one month postoperatively, 49 out of 51 (96%) patients were completely healed. Five patients (5/44, 11%) developed recurrent or new ulcers within 3 years of surgery. Two patients were re-operated on (2/44, 5%). Between 3 and 10 years after surgery, 9 patients (9/33, 27%) had a history of recurrent ulcers, and 6 (6/33, 18%) had a history of new ulcers, a total of 15 patients (15/33, 45%). Of these, three needed re-operation (3/33, 9 %). The health status values using a visual analogue rating scale were 70 (median) at 3 and 10 years compared with 30 (median) preoperatively. The good initial healing, the low ulcer recurrence rate and the raise in health status indicate the value of a structured treatment programme, especially for the first few postoperative years.
