Purpose: To assess the diagnostic value of retrospectively fused PET/MRI by comparing the detection rates (DRs) of fused 64CuCl2 PET/MRI vs. fused 18F-Choline PET/MRI in patients with suspected prostatic cancer (PCa) recurrence. The secondary objective was to compare the DRs of fused PET/MRI vs. those of the separate imaging modalities. Methods: We retrospectively evaluated 50 PCa patients with biochemical relapse after radical prostatectomy (RP) or radiotherapy (RT). All patients underwent 64CuCl2 PET/CT, 18F-Choline PET/CT, and multiparametric magnetic resonance imaging (mpMRI) within 15 days. Fused 64CuCl2-PET/MRI and fused 18F-Choline PET/MRI images were obtained by retrospective co-registration of MRI and PET images. Experienced readers interpreted the images, and the DRs of each imaging modality were assessed. Results: In the patient-based analysis, overall DRs of fused 64CuCl2 PET/MRI, fused 18F-Choline PET/MRI, 64CuCl2 PET/CT, 18F-Choline PET/CT, and mpMRI were 88%, 68%, 82%, 56%, and 74%, respectively. In the lesion-based analysis, overall DRs of fused 64CuCl2 PET/MRI, fused 18F-Choline PET/MRI, 64CuCl2 PET/CT, 18 F-Choline PET/CT, and mpMRI were 95%, 66%, 87%, 58%, and 71%, respectively. Conclusions: Retrospectively fused PET/MRI is able to overcome the limitations of the separate interpretation of the individual imaging modalities. Fused 64CuCl2 PET/MRI provided the highest diagnostic performance in the detection of PCa local relapse. [ABSTRACT FROM AUTHOR]

Introduction: The COVID-19 pandemic has posed significant challenges to the education system, leading to changes in student academic performance and mental health. The aim of this study was to evaluate variables relating to changes in academic performance and mental health during the pandemic., Methods: We carried out a cross-sectional study from 28 February 2022 to 13 April 2022, during the free SARS-CoV-2 screening campaign offered by Sapienza University of Rome. A structured questionnaire was constructed to explore the decline in academic performance during the COVID-19 pandemic. The Coronavirus Anxiety Scale (CAS), a validated self-reporting mental health screener of dysfunctional anxiety associated with the coronavirus crisis, was used., Results: A sample of 1,134 students was enrolled. A total of 25.4% of the participants reported a decline in academic performance. In addition, Coronavirus Anxiety Scale scores revealed that 133 (11.5%) students had a dysfunctional anxiety problem due to COVID-19. A multivariable logistic regression model showed that being a senior student (aOR: 0.70 95% CI: 0.52-0.96) and having good financial status (aOR: 0.64, 95% CI: 0.47-0.88) decrease the likelihood of a decline in academic performance, while not being Italian (aOR: 2.12, 95% CI: 1.29-3.48), having felt the need for psychological support (aOR: 2.58, 95% CI: 1.87-3.55) and being enrolled in a science/technology faculty (aOR: 1.81, 95% CI: 1.27-2.57) were more likely to result in a decline in academic performance., Conclusion: Our results show that the pandemic has affected academic performance. The COVID-19 emergency highlighted the importance of considering mental health and economic status in policymaking to effectively support students., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Siena, Mussetto, Renzi, Baccolini, Migliara, Sciurti, Covelli, De Vito, Marzuillo, Villari and Massimi.)
