Le cripto-attività nella disciplina MiCAr e la finanziarietà delle "cripto-attività non finanziarie"
Lo scritto ripercorre in chiave diacronica – dalle origini sino all’adozione del Reg. Ue n. 2023/1114 del 31 maggio 2023 (MiCAr ) – le ragioni dello sviluppo delle cripto-attività collegate alla blockchain e alle tecnologie basate su registri distribuiti (DLT). Con il Reg. MiCAr vengono per la prima volta classificate e regolate, in ambito europeo, le “cripto-attività non finanziarie” (utility e monetary tokens), determinandosi così una contrapposizione tra queste e gli strumenti finanziari emessi e circolanti mediante tecnologia DLT ex art. 1, co. 2, TUF. L’antitesi tra le due tipologie di cripto-attività si dimostra – pur in una prospettiva che non nasconde dubbi e profili di criticità – almeno in taluni casi, più apparente che reale. La potenziale negoziabilità delle cripto-attività MiCAr sembra attribuire loro un carattere di finanziarietà, trasformando un fenomeno originariamente e tipicamente non finanziario in una fattispecie essenzialmente finanziaria. Ci si chiede, in chiave problematica, se il legislatore europeo non avrebbe, quindi, potuto ricondurre, nell’alveo degli investimenti finanziari basati su DLT (security o investment token o prodotti finanziari di matrice interna), le cripto-attività MiCAr caratterizzate da finanziarietà, applicando, con gli adattamenti normativi necessari, le discipline e i presidi già esistenti e propri di questi. Per altro verso, ci si chiede, altresì, se le cripto-attività autenticamente non finanziarie, come gli utility tokens e le stablecoins, non negoziate su piattaforme di trading, richiedessero davvero una così ampia e articolata disciplina come quella dettata dal MiCAr, che ricalca, peraltro, quella di matrice finanziaria, non sfuggendo gli utility tokens alla tutela consumeristica già esistente e le stablecoins a quella dei prestatori di servizi di pagamento di moneta elettronica

L'impresa sostenibile (non benefit)
Lo scritto approfondisce il tema della configurabilità dell'impresa sostenibile (non benefit) nel vigente sistema normativo. Si fa strada l'idea che tali imprese possano perseguire il proprio oggetto sociale operando nell'ambito di un paradigma funzionale essenzialmente lucrativo o comunque egoistico
Dermoscopy and methyl aminolevulinate: A study for detection and evaluation of field cancerization
Actinic keratosis (AK) is a keratinocyte intraepidermal neoplasia UV light
–
induced that frequently appears in
sun-exposed areas of the skin. Although historically AK was de
fi
ned as
“
precancerous
”
, actually it is considered
as the earliest stage of squamous cell carcinoma (SCC) in situ. Since AKs can progress into invasive SCC, their
treatment isrecommended. AKsrarely developasa singlelesion;usually multiplelesions commonly affect anen-
tire area of chronically actinic damaged skin. This has led to the concept of
“
fi
eld cancerization
”
, an area chroni-
cally sun-exposed that surrounds peripherally visible lesions, in which are individualized subclinical alterations.
One of the main principles endpoint in the management of AKs is the evaluation and the treatment of
fi
eld
cancerization. In this view, in order to detect and quantify
fi
eld cancerization, we employed a method based
on the topical application of methyl aminolevulinate (MAL) and the detection of the
fl
uorescence emitted by
its metabolite Protoporphyrin IX (PpIX); then, considering the extension and the intensity of measured
fl
uores-
cence, we create a score of
fi
eld cancerization. The results show that patients underwent to daylight PDT had a
reduction of total score, from T0 to T2. Whereas in the group untreated we observed a stability of total score or
a slightly worse. So, the method and the score used allows to evaluate with a good approximation the dimension
of
fi
eld cancerization and show the modi
fi
cation of it after treatment
The performance of the Italian housing market and its effects on the financial system
Developments in the real-estate sector are of crucial importance for the business cycle and financial stability. This study analyses developments in the Italian housing market on the basis of both real and financial variables. Following the sharp contraction of the market during the financial crisis and the more general fall in economic activity, a few signals suggests that the recession in the housing market is easing somewhat. However, the degree of uncertainty remains considerable. In recent months the ratio between the flow of bad debts to total outstanding loans to households and construction firms has reached the highest levels since the beginning of the decade. The paper also investigates three issues of a more structural nature. First, it examines the performance and the regulatory framework of real-estate investment funds in Italy. Second, it analyses the main characteristics of the taxation of residential housing, with reference to ownership, rentals and transactions. Finally, the paper estimates the impact on residential house prices of the growing demand for housing services by immigrants.housing market cycle, transactions, rentals, residential house prices, mortgages, real-estate investment funds, taxation of residential housing

Three vs. Four Cycles of Neoadjuvant Chemotherapy for Localized Muscle Invasive Bladder Cancer Undergoing Radical Cystectomy: A Retrospective Multi-Institutional Analysis
Three or four cycles of cisplatin-based chemotherapy is the standard neoadjuvant treatment prior to cystectomy in patients with muscle-invasive bladder cancer. Although NCCN guidelines recommend 4 cycles of cisplatin-gemcitabine, three cycles are also commonly administered in clinical practice. In this multicenter retrospective study, we assessed a large and homogenous cohort of patients with urothelial bladder cancer (UBC) treated with three or four cycles of neoadjuvant cisplatin-gemcitabine followed by radical cystectomy, in order to explore whether three vs. four cycles were associated with different outcomes
Neutrophil percentage-to-albumin ratio predicts mortality in bladder cancer patients treated with neoadjuvant chemotherapy followed by radical cystectomy
To investigate the prognostic role of neutrophil percentage-to-albumin ratio (NPAR) in muscle-invasive bladder cancer (MIBC) patients treated with neoadjuvant chemotherapy (NAC) and radical cystectomy (RC)
Changes in renal function after nephroureterectomy for upper urinary tract carcinoma: analysis of a large multicenter cohort (Radical Nephroureterectomy Outcomes (RaNeO) Research Consortium)
Purpose To investigate prevalence and predictors of renal function variation in a multicenter cohort treated with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). Methods Patients from 17 tertiary centers were included. Renal function variation was evaluated at postoperative day (POD)-1, 6 and 12 months. Timepoints differences were Delta 1 = POD-1 eGFR - baseline eGFR; Delta 2 = 6 months eGFR - POD-1 eGFR; Delta 3 = 12 months eGFR - 6 months eGFR. We defined POD-1 acute kidney injury (AKI) as an increase in serum creatinine by >= 0.3 mg/dl or a 1.5 1.9-fold from baseline. Additionally, a cutoff of 60 ml/min in eGFR was considered to define renal function decline at 6 and 12 months. Logistic regression (LR) and linear mixed (LM) models were used to evaluate the association between clinical factors and eGFR decline and their interaction with follow-up. Results A total of 576 were included, of these 409(71.0%) and 403(70.0%) had an eGFR < 60 ml/min at 6 and 12 months, respectively, and 239(41.5%) developed POD-1 AKI. In multivariable LR analysis, age (Odds Ratio, OR 1.05, p < 0.001), male gender (OR 0.44, p = 0.003), POD-1 AKI (OR 2.88, p < 0.001) and preoperative eGFR < 60 ml/min (OR 7.58, p < 0.001) were predictors of renal function decline at 6 months. Age (OR 1.06, p < 0.001), coronary artery disease (OR 2.68, p = 0.007), POD-1 AKI (OR 1.83, p = 0.02), and preoperative eGFR < 60 ml/min (OR 7.80, p < 0.001) were predictors of renal function decline at 12 months. In LM models, age (p = 0.019), hydronephrosis (p < 0.001), POD-1 AKI (p < 0.001) and pT-stage (p = 0.001) influenced renal function variation (ss 9.2 +/- 0.7, p < 0.001) during follow-up. Conclusion Age, preoperative eGFR and POD-1 AKI are independent predictors of 6 and 12 months renal function decline after RNU for UTUC
Adaptation and diagnostic potential of a commercial cat interferon gamma release assay for the detection of Mycobacterium bovis infection in African lions (Panthera leo)
CITATION: Gumbo, R. et al. 2022. Adaptation and diagnostic potential of a commercial cat interferon gamma release assay for the detection of Mycobacterium bovis infection in African lions (Panthera leo). Pathogens, 11:765, doi:10.3390/pathogens11070765.The original publication is available at https://www.mdpi.comMycobacterium bovis (M. bovis) infection in wildlife, including lions (Panthera leo), has
implications for individual and population health. Tools for the detection of infected lions are needed
for diagnosis and disease surveillance. This study aimed to evaluate the Mabtech Cat interferon
gamma (IFN-γ) ELISABasic kit for detection of native lion IFN-γ in whole blood samples stimulated
using the QuantiFERON® TB Gold Plus (QFT) platform as a potential diagnostic assay. The ELISA
was able to detect lion IFN-γ in mitogen-stimulated samples, with good parallelism, linearity, and
a working range of 15.6–500 pg/mL. Minimal matrix interference was observed in the recovery of
domestic cat rIFN-γ in lion plasma. Both intra- and inter-assay reproducibility had a coefficient
of variation less than 10%, while the limit of detection and quantification were 7.8 pg/mL and
31.2 pg/mL, respectively. The diagnostic performance of the QFT Mabtech Cat interferon gamma
release assay (IGRA) was determined using mycobacterial antigen-stimulated samples from M. bovis
culture-confirmed infected (n = 8) and uninfected (n = 4) lions. A lion-specific cut-off value (33 pg/mL)
was calculated, and the sensitivity and specificity were determined to be 87.5% and 100%, respectively.
Although additional samples should be tested, the QFT Mabtech Cat IGRA could identify M. bovisinfected African lions.https://www.mdpi.com/2076-0817/11/7/765Publisher's versio
