Abstract
Quantum chemical studies employing combined density functional and multireference configuration interaction methods suggest five excited electronic states to be involved in the prompt and delayed fluorescence emission of TpAT-tFFO. Three of them, a pair of singlet and triplet charge transfer (CT) states (S1 and T1) and a locally excited (LE) triplet state (T3), can be associated with the (Me → N) conformer, the other two CT-type states (S2 and T2) form the lowest excited singlet and triplet states of the (Me → Ph) conformer. The two conformers, which differ in essence by the shearing angle of the face-to-face aligned donor and acceptor moieties, are easily interconverted in the electronic ground state whereas the reorganization energy is substantial in the excited singlet state, thus explaining the two experimentally observed time constants of prompt fluorescence emission. Forward and reverse intersystem crossing between the singlet and triplet CT states is mediated by vibronic spin–orbit interactions involving the LE T3 state. Low-frequency vibrational modes altering the distance and alignment of the donor and acceptor π-systems tune the S1 and T3 states (likewise S2 and T3) into and out of resonance. The enhancement of intersystem crossing due to the interplay of vibronic and spin–orbit coupling is considered a general feature of organic through-space charge-transfer thermally activated delayed fluorescence emitters. DFT/MRCI quantum chemical studies suggest five excited electronic states to be involved in the prompt and delayed fluorescence emission of TpAT-tFFO.![]()

Abstract
INTRODUCTION Urethral or upper urinary tract (UUT) recurrence of urothelial carcinoma (UC) after radical cystectomy (RC) are rare (4-6%), and their diagnosis usually occurs within the first two years. Although it is known that its early detection offers benefit in terms of survival, currently there are no clear recommendations for the detection of recurrence in the remnant urothelium (RU). Our aim is to determine the diagnostic value of urinary cytology for the detection of recurrences in the RU and to estimate its impact as an early diagnostic method on survival. MATERIAL AND METHODS Retrospective review of patients who underwent RC for urothelial carcinoma between 2008-2016, with a follow-up of at least 24 months. RESULTS The study included 142 patients. In a median follow-up of 68.5 months, nine patients (6.3%) presented recurrences in the RU (urethra: four, UUT: four, synchronous: one). The sensitivity and specificity of urinary cytology for the diagnosis of UUT recurrences were 20% and 96%, respectively. No significant differences were found between overall survival and cancer-specific survival among patients according to the urinary cytology results. CONCLUSION Recurrences in the RU after RC are infrequent; our study has shown that urinary cytology offers a low sensitivity for their diagnoses. For these reasons, we do not consider that urinary cytology provides useful information for surveillance of these patients.

Abstract
Introduction Telemedicine provides remote clinical support through technology tools. It can facilitate medical care delivery while reducing unnecessary office visits. The COVID-19 outbreak has caused an abrupt change in our daily urological practice, where teleconsultations play a crucial role. Objective To provide practical recommendations for the effective use of technological tools in telemedicine. Materials and methods A literature search was conducted on Medline until April 2020. We selected the most relevant articles related to “telemedicine” and “smart working” that could provide valuable information. Results Telemedicine refers to the use of electronic information and telecommunication tools to provide remote clinical health care support. Smart working is a working approach that uses new or existing technologies to improve performance. Telemedicine is becoming a useful and fundamental tool during the COVID-19 pandemic and will be even more in the future. It is time for us to officially give telemedicine the place it deserves in clinical practice, and it is our responsibility to adapt and familiarize with all the tools and possible strategies for its optimal implementation. We must guarantee that the quality of care received by patients and perceived by them and their families is of the highest standard. Conclusions Telemedicine facilitates remote specialized urological clinical support and solves problems caused by limited patient mobility or transfer, reduces unnecessary visits to clinics and is useful to reduce the risk of COVID-19 viral transmission.
