RESUMO
BACKGROUND: Older people hospitalized for COVID-19 are at highest risk of death. Frailty Assessment can detect heterogeneity in risk among people of the same chronological age. We investigated the association between frailty and in-hospital and medium-term mortality in middle-aged and older adults with COVID-19 during the first two pandemic waves. METHODS: This study is an observational multicenter study. We recorded sociodemographic factors (age, sex), smoking status, date of symptom onset, biological data, need for supplemental oxygen, comorbidities, cognitive and functional status, in-hospital mortality. We calculated a Frailty Index (FI) as the ratio between deficits presented and total deficits considered for each patient (theoretical range 0-1). We also assessed the Clinical Frailty Scale (CFS). Mortality at follow-up was ascertained from a regional registry. RESULTS: In total, 1344 patients were included; median age 68 years (Q1-Q3, 56-79); 857 (64%) were men. Median CFS score was 3 (Q1-Q3 2-5) and was lower in younger vs. older patients. Median FI was 0.06 (Q1-Q3 0.03-0.09) and increased with increasing age. Overall, 244 (18%) patients died in-hospital and 288 (22%) over a median follow-up of 253 days. FI and CFS were significantly associated with risk of death. In two different models using the same covariates, each increment of 0.1 in FI increased the overall hazard of death by 35% (HR=1.35, 95%CI 1.23-1.48), similar to the hazard for each increment of CFS (HR=1.37, 95%CI 1.25-1.50). CONCLUSIONS: Frailty, assessed with the FI or CFS, predicts in-hospital and medium-term mortality and may help estimate vulnerability in middle-aged and older COVID-19 patients.

Background: Proximal Row Carpectomy (PRC) is a widespread, safe and effective salvage surgical procedure for wrist arthritis. Some authors believe that PRC results in low grip strength (GS), due to the loss of carpal height, supporting the idea to discourage PRC in high-demanding patients. Resurfacing Capitate Prosthesis Implant (RCPI) allows extending the indication for PRC also in case of deformity and/or arthritis of the head of capitate, with possible implications of clinical outcomes, including GS. Methods: Retrospective multicentre study on a population of active workers, affected by secondary post traumatic wrist arthritis, who underwent PRC (27 patients) or PRC + RCPI (20 patients), Primary outcome was to assess GS between PRC and PRC + RCPI. Secondary outcome was to assess CHR and to search for any possible contributors to GS. Active range of motion (AROM), hand function (DASH, Work-DASH, VAS, PRWHE), pain, time to return to work, job maintenance, major complications and general satisfaction were also assessed. Results: PRC + RCPI results in more GS maintenance compared with PRC alone, with higher values of CHR. CHR values were associated with GS with a good correlation. According to linear regression model analysis within PRC + RCPI group (GS-CHR), it is esteemed that the increase in parameter CHR is associated with an increase in parameter GS. Looking at a multiple linear regression model analysis built on the whole sample (GS% increase - (group × CHR) + GS% pre-operative). It is estimated that the increase of one unit of the GS coefficient is associated with an increase in GS% increase. Furthermore, higher pre-operative GS values positively influence post-operative GS. No differences were revealed between the two treatments in terms of the remaining secondary outcomes. Conclusions: PRC alone and PRC + RCPI are both effective salvage procedures for wrist arthritis. RCPI provides a better GS preservation, in part due to the carpal height preservation.

OBJECTIVES: The aim of this study was to report our experience with early stage glioblastoma (e-GB) and to investigate the possible clinical and imaging features that may be helpful to the radiologist to correctly diagnose this entity. METHODS: We performed a retrospective research of patients diagnosed with glioblastoma at two hospitals during a 10-year period. We reviewed all pre-operative MR and included only patients with early stage GB lesions, characterized by hyperintense on T2-weighted signal, with or without contrast-enhancement at post-contrast T1-weighted images, without "classic" imaging appearance of GB (necrosis, haemorrhage, oedema). All preoperative MR were evaluated by an experienced neuroradiologist and information on patients' demographics, clinical presentation, follow-up, and histopathology results study were collected. When available, preoperative CT examination was also evaluated. RESULTS: We found 14 e-GBs in 13 patients (9 males, 4 females, median age 63 years) among 660 patients diagnosed with GB between 2010 and 2020. In 10 lesions, serial imaging revealed the transformation of e-GB in classic glioblastoma in a median time of 3 months. Clinical presentation included stroke-like symptoms, vertigo, seizures and confusion. Preoperative plain CT was performed in 8/13 cases and in 7 e-GBs presented as a hyperdense lesion. Ten out of 14 lesions transformed in classic GB before surgical intervention or biopsy. All lesions revealed typical immunohistochemical pattern of primary glioblastoma. CONCLUSIONS: E-GB is a rare entity that can often lead to misdiagnosis. However, the radiologist should be aware of its imaging appearance to suggest the diagnosis and to request close imaging follow-up, hopefully improving the prognosis of this very aggressive disease.

OBJECTIVES: To evaluate accuracy and inter-observer variability using Vesical Imaging-Reporting and Data System (VI-RADS) for discrimination between non-muscle invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC). METHODS: Between September 2017 and July 2018, 78 patients referred for suspected bladder cancer underwent multiparametric MRI of the bladder (mpMRI) prior to transurethral resection of bladder tumor (TURBT). All mpMRI were reviewed by two radiologists, who scored each lesion according to VI-RADS. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for each VI-RADS cutoff. Receiver operating characteristics curves were used to evaluate the performance of mpMRI. The Æ statistics was used to estimate inter-reader agreement. RESULTS: Seventy-five patients were included in the final analysis, 53 with NMIBC and 22 with MIBC. Sensitivity and specificity were 91% and 89% for reader 1 and 82% and 85% for reader 2 respectively when the cutoff VI-RADS > 2 was used to define MIBC. At the same cutoff, PPV and NPV were 77% and 96% for reader 1 and 69% and 92% for reader 2. When the cutoff VI-RADS > 3 was used, sensitivity and specificity were 82% and 94% for reader 1 and 77% and 89% for reader 2. Corresponding PPV and NPV were 86% and 93% for reader 1 and 74% and 91% for reader 2. Area under curve was 0.926 and 0.873 for reader 1 and 2 respectively. Inter-reader agreement was good for the overall score (Æ = 0.731). CONCLUSIONS: VI-RADS is accurate in differentiating MIBC from NMIBC. Inter-reader agreement is overall good. KEY POINTS: ⢠Traditionally, the local staging of bladder cancer relies on transurethral resection of bladder tumor. ⢠However, transurethral resection of bladder tumor carries a significant risk of understaging a cancer; therefore, more accurate, faster, and non-invasive staging techniques are needed to improve outcomes. ⢠Multiparametric MRI has proved to be the best imaging modality for local staging; therefore, its use in suitable patients has the potential to expedite radical treatment when necessary and non-invasive diagnosis in patients with poor fitness.

We aimed to review the current state-of-the-art imaging methods used for primary and secondary staging of prostate cancer, mainly focusing on multiparametric magnetic resonance imaging and positron-emission tomography/computed tomography with new radiotracers. An expert panel of urologists, radiologists and nuclear medicine physicians with wide experience in prostate cancer led a PubMed/MEDLINE search for prospective, retrospective original research, systematic review, meta-analyses and clinical guidelines for local and systemic staging of the primary tumor and recurrence disease after treatment. Despite magnetic resonance imaging having low sensitivity for microscopic extracapsular extension, it is now a mainstay of prostate cancer diagnosis and local staging, and is becoming a crucial tool in treatment planning. Cross-sectional imaging for nodal staging, such as computed tomography and magnetic resonance imaging, is clinically useless even in high-risk patients, but is still suggested by current clinical guidelines. Positron-emission tomography/computed tomography with newer tracers has some advantage over conventional images, but is not cost-effective. Bone scan and computed tomography are often useless in early biochemical relapse, when salvage treatments are potentially curative. New imaging modalities, such as prostate-specific membrane antigen positron-emission tomography/computed tomography and whole-body magnetic resonance imaging, are showing promising results for early local and systemic detection. Newer imaging techniques, such as multiparametric magnetic resonance imaging, whole-body magnetic resonance imaging and positron-emission tomography/computed tomography with prostate-specific membrane antigen, have the potential to fill the historical limitations of conventional imaging methods in some clinical situations of primary and secondary staging of prostate cancer.

Cardiovascular magnetic resonance (CMR) has an emerging role in aortic valve disease evaluation, becoming an all-in-one technique. CMR evaluation of the anatomy and flow through the aortic valve has a higher reproducibility than echocardiography. Its unique ability of in vivo myocardial tissue characterization, significantly improves the risk stratification and management of patients. In addition, CMR is equivalent to cardiac CT angiography for trans-aortic valvular implantation and surgical aortic valve replacement planning; on the other hand, its role in the evaluation of ventricular function improving and post-treatment complications is undisputed. This review encompasses the existing literature regarding the role of CMR in aortic valve disease, exploring all the aspects of the disease, from diagnosis to prognosis.

PURPOSE: To validate a novel consensus method, called target-in-target, combining human analysis of mpMRI with automated CAD system analysis, with the aim to increasing the prostate cancer detection rate of targeted biopsies. METHODS: A cohort of 420 patients was enrolled and 253 patients were rolled out, due to exclusion criteria. 167 patients, underwent diagnostic 3T MpMRI. Two expert radiologists evaluated the exams adopting PI-RADSv2 and CAD system. When a CAD target overlapped with a radiologic one, we performed the biopsy in the overlapping area which we defined as target-in-target. Targeted TRUS-MRI fusion biopsy was performed in 63 patients with a total of 212 targets. The MRI data of all targets were quantitatively analyzed, and diagnostic findings were compared to pathologist's biopsy reports. RESULTS: CAD system diagnostic performance exhibited sensitivity and specificity scores of 55.2% and 74.1% [AUC = 0.63 (0.54 ÷ 0.71)] , respectively. Human readers achieved an AUC value, in ROC analysis, of 0.71 (0.63 ÷ 0.79). The target-in-target method provided a detection rate per targeted biopsy core of 81.8 % vs. a detection rate per targeted biopsy core of 68.6 % for pure PI-RADS based on target definitions. The higher per-core detection rate of the target-in-target approach was achieved irrespective of the presence of technical flaws and artifacts. CONCLUSIONS: A novel consensus method combining human reader evaluation with automated CAD system analysis of mpMRI to define prostate biopsy targets was shown to improve the detection rate per biopsy core of TRUS-MRI fusion biopsies. Results suggest that the combination of CAD system analysis and human reader evaluation is a winning strategy to improve targeted biopsy efficiency.

BACKGROUND: Transrectal ultrasound-guided biopsy (TRUS-Bx) is recommended by the European Urology Association (EAU) as the first diagnostic modality for men at risk of prostate cancer (PCa). Current EAU guidelines reserve the use of multiparametric MRI to target or guide any repeat biopsy (mpMRI-Bx). It remains uncertain if TRUS-Bx is effective as a first strategy in terms of costs, diagnostic performance, time to diagnosis, and triage for individualised therapy. OBJECTIVE: To determine the diagnostic and treatment costs and the effectiveness of pathways incorporating mpMRI-Bx compared to TRUS-Bx in men at high risk of PCa. DESIGN, SETTING, AND PARTICIPANTS: A cost and time analysis was performed using data from a randomised single-centre study of 1140 patients (prostate-specific antigen >4ng/ml) divided into two groups: 570 patients underwent an initial TRUS-Bx and 570 underwent 3-T mpMRI-Bx. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Budget analyses were used to compare the diagnostic strategies using reimbursement data from the Italian National Health Security system. Analyses of reimbursable diagnostic and treatment costs were undertaken separately. Histologic outcomes, pathway diagnostic accuracy, therapy choices, and time to diagnosis were compared. RESULTS AND LIMITATIONS: The cumulative diagnosis costs were 14.6% greater for the mpMRI-Bx pathway than for the TRUS strategy, and 5.2-6.0% higher for therapy. Diagnostic costs were 228 946 for mpMRI-Bx and 199 750 for TRUS-Bx, and the corresponding therapy costs were 1 912 000 and 1 802 800. The mpMRI-Bx strategy was highly effective in excluding clinically significant disease (Gleason ≥7; sensitivity and negative predictive value both 100%, 95% confidence interval 98-100%). The time to diagnosis was significantly shorter for the mpMRI-Bx (median 4.0 mo interquartile range [IQR] 3-6) than for the TRUS-Bx strategy (median 6 mo, IQR 4-12; p<0.001). Limitations include the lack of data on costs associated with treatment-related complications and follow-up data. CONCLUSIONS: The mpMRI-Bx strategy is effective for diagnosing patients with a clinical suspicion of PCa and provides more accurate diagnosis, with combined diagnosis and therapy costs only moderately higher than for the standard strategy. PATIENT SUMMARY: It is a matter of debate whether a diagnostic pathway that incorporates multiparametric magnetic resonance imaging (MRI) as the first-line test before performing any type of biopsy in men suspected of having prostate cancer (PCa) is cost-effective. Our analysis of the costs for men suspected of harbouring PCa revealed higher diagnostic costs for the MRI approach, with the benefits of greater diagnostic accuracy. Moreover, the combined diagnostic and treatment costs are only modestly higher whenever the same treatment for all patients is considered.
