Objective: Patient-centered care and shared decision making (SDM) are generally recognized as the gold standard for medical consultations, especially for preference-sensitive decisions. However, little is known about psychological patient characteristics that influence patient-reported preferences. We set out to explore the role of personality and anxiety for a preference-sensitive decision in bladder cancer patients (choice of urinary diversion, UD) and to determine if anxiety predicts patients' participation preferences.

Article Synopsis
  • The study aimed to compare emergency room visits for pyelonephritis before and during the COVID-19 pandemic to assess the impact on patient outcomes.
  • Findings showed a significant decrease in emergency room visits during the pandemic (42.1% reduction), but an increase in severe adverse outcomes among patients admitted in that period.
  • The authors recommend health authorities launch information campaigns to encourage patients to seek emergency care for serious symptoms during pandemic waves to prevent further adverse outcomes.

Background: Multiparametric magnetic resonance imaging using the Prostate Imaging Reporting and Data System version 2.1 allows for a personalized, risk-stratified approach to indicating prostate biopsies (PBx) in order to reduce PBx and concomitant complications in men with suspected prostate cancer (PCa). One way to achieve this goal is to implement the risk-stratified pathway (RSP) using the Rotterdam Prostate Cancer Risk Calculator.

Background: Over the past decade prostate cancer (PCa) diagnostic approaches have evolved away from aggressive prostate-specific antigen (PSA) screening. While a goal of these changes is to decrease over diagnosis and treatment, little is known about the downstream effects on PCa risk distribution at the time of diagnosis. To better understand these effects, we used a national cohort of men to investigate temporal trends in PCa risk profile at diagnosis.

Transurethral resection (TUR) of bladder tumours does not only serve diagnostic purposes by securing histological proof of the disease but might also resemble the final therapy. During recent years, technical innovations improved the intraoperative detection and visibility of tumourous lesions during TUR. The most important techniques, which have individually found their way into international guidelines, are photodynamic imaging (PDI) and narrowband imaging (NBI).

Histopathological differentiation between severe urocystitis with reactive urothelial atypia and carcinoma in situ (CIS) can be difficult, particularly after a treatment that deliberately induces an inflammatory reaction, such as intravesical instillation of Bacillus Calmette-Guèrin. However, precise grading in bladder cancer is critical for therapeutic decision making and thus requires reliable immunohistochemical biomarkers. Herein, an exemplary potential biomarker in bladder cancer was identified by the novel approach of Fourier transform infrared imaging for label-free tissue annotation of tissue thin sections.

Introduction: Given the ongoing controversies regarding its benefit, prostate specific antigen based prostate cancer screening should be offered with patient preferences in mind. Understanding subsets of men who may or may not choose prostate specific antigen screening and their associated characteristics may allow more efficient care and may identify subsets of patients for whom additional counseling is warranted.

Methods: We analyzed male participants from the 2001 to 2010 cycles of the NHANES (National Health and Nutrition Examination Survey) who were 40 years old or older, and without a history of prostate cancer, recent prostate manipulation or hormone therapy use (8,133).
