Abstract
AIMS An increase in right atrial pressure is a common feature of acute decompensated heart failure (ADHF). Such increased pressure leads to persistent kidney congestion. A marker to guide optimal diuretic therapy is missing. We aim to correlate intrarenal Doppler (IRD) ultrasound in ADHF patients with clinical outcomes to assess whether renal haemodynamic parameter changes are useful for monitoring kidney congestion. METHODS AND RESULTS Between December 2018 and January 2020, ADHF patients requiring intravenous diuretic therapy for at least 48 h were considered for study selection. An IRD blinded examination was performed on Days 1, 3, and 5, and clinical and laboratory parameters were recorded. Venous Doppler profiles (VDP) were classified as continuous (C), pulsatile (P), biphasic (B), or monophasic (M) according to the congestion degree; B and M profiles were considered deranged. A VDP improvement (VDPimp) was defined as a change of ≥1 pattern degree or maintenance of C or P patterns. An arterial resistive index (RI) > 0.8 was considered elevated. Outcomes of death and rehospitalization were gathered at 60 days. Data were assessed by regression and Kaplan-Meier analyses. All 177 ADHF patients admitted were screened, and 72 were enrolled [27 females-median age 81 (76-87) years-median ejection fraction 40% (30-52)]. The VDP derangement decreased from 79.2% on Day 1 to 51.4% on Day 5 (P < 0.05). The RI elevation decreased from 60.6% on Day 1 to 43.1% on Day 5 (P < 0.05). At Day 5, VDPimp was registered in over half of the patients (59.7%). At Day 5, signs of congestion (dyspnoea/oedema/rales), fluid accumulation (pleural/peritoneal fluid), haematocrit, and brain natriuretic peptide improved (P > 0.05). After 60 days, 12 (16.7%) patients were readmitted and 9 (12.5%) died. The VDPimp was identified as the unique independent factor associated with readmission [Hazard Ratio (HR) 0.22, 95% (confidence interval) CI 0.05-0.94, P = 0.04] and death (HR 0.07, 95% CI 0.01-0.68, P = 0.02), with significantly better outcomes identified in VDPimp patients (log-rank test, P < 0.05). CONCLUSION Decongestion may be associated with improvements in many clinical and instrumental parameters, but only VDPimp was associated with better clinical outcomes. The VDPimp should be incorporated in ad hoc ADHF clinical trials to better define its role in everyday practice.

Abstract
Background: The early detection of neurocognitive disorders, especially when mild, is a key issue of health care systems including the Italian Dementia National Plan. The Mini-Mental State Examination (MMSE), i.e., the reference screening tool for dementia in Italian Memory Clinics, has low sensitivity in detecting mild cognitive impairment (MCI) or mild dementia. Objective: Availability of a 10-minute screening test sensitive to MCI and mild dementia, such as the Montreal Cognitive Assessment (MoCA), is relevant in the field. This study presents initial validity and reliability data for the Italian version of MoCA 7.1 that is being collected as part of a large ongoing longitudinal study to evaluate the rate of incident MCI and dementia in older adults. Methods: MoCA 7.1 and MMSE were administered to cognitive impaired patients (n = 469; 214 with MCI, 255 with dementia; mean age: 75.5; 52% females,) and healthy older adults (n = 123, mean age: 69.7, 64 % females). Results: Test-retest (0.945, p < 0.001) and inter-rater (0.999, p < 0.001) reliability of MoCA 7.1, assessed on randomly selected participants with normal cognition, MCI, dementia, were significant. MoCA 7.1 showed adequate sensitivity (95.3%) and specificity (84.5%) in detecting MCI compared to MMSE (sensitivity: 53.8%; specificity: 87.5%). The Area Under the Curve of MoCA 7.1 was significantly greater than that of MMSE (0.963 versus 0.742). MoCA 7.1 showed similar results in detecting both MCI and dementia. Conclusion: MoCA 7.1 is a reliable and useful tool that can aid in the diagnosis of MCI and dementia in the Italian population.

Abstract
BACKGROUND Knowledge on the main clinical and prognostic characteristics of older multimorbid subjects with liver cirrhosis (LC) admitted to acute medical wards is scarce. OBJECTIVES To estimate the prevalence of LC among older patients admitted to acute medical wards and to assess the main clinical characteristics of LC along with its association with major clinical outcomes and to explore the possibility that well-distinguished phenotypic profiles of LC have classificatory and prognostic properties. METHODS A cohort of 6,193 older subjects hospitalised between 2010 and 2018 and included in the REPOSI registry was analysed. RESULTS LC was diagnosed in 315 patients (5%). LC was associated with rehospitalisation (age-sex adjusted hazard ratio, [aHR] 1.44; 95% CI, 1.10-1.88) and with mortality after discharge, independently of all confounders (multiple aHR, 2.1; 95% CI, 1.37-3.22), but not with in-hospital mortality and incident disability. Three main clinical phenotypes of LC patients were recognised: relatively fit subjects (FIT, N = 150), subjects characterised by poor social support (PSS, N = 89) and, finally, subjects with disability and multimorbidity (D&M, N = 76). PSS subjects had an increased incident disability (35% vs 13%, P < 0.05) compared to FIT. D&M patients had a higher mortality (in-hospital: 12% vs 3%/1%, P < 0.01; post-discharge: 41% vs 12%/15%, P < 0.01) and less rehospitalisation (10% vs 32%/34%, P < 0.01) compared to PSS and FIT. CONCLUSIONS LC has a relatively low prevalence in older hospitalised subjects but, when present, accounts for worse post-discharge outcomes. Phenotypic analysis unravelled the heterogeneity of LC older population and the association of selected phenotypes with different clinical and prognostic features.

Abstract
Abstract
Background
Acute heart failure (AHF) is often accompanied by impairment in renal function. A profound derangement of normal abdominal haemodynamic is always present during this clinical phase.
Methods
14 patients (6 F – mean age 80 – mean EF 0.39) admitted for acute heart failure underwent cardiac and renal Echo Doppler examination at day 1-3-5 of Hospital stay. Parameters of arterial and venous flow within cortical right kidney were recorded. Venous Doppler Profile (VDP) was classified as: continuous (C), pulsatile (P), biphasic (B) or monophasic (M) according to the growing degree of derangement. Arterial resistive index (RI) >0.8 was considered elevated. Correlation between renal hemodynamic (and its changes) with biohumoral and echo parameters was sought.
Outcome
At day 1 VDP was M or B in 8 patients (57%) and in four (50%) of them dropped to C or P at day 5. RI was elevated in 8 patients at day 1 while only in 4 at day 5. VDP and RI were not related to EF or BNP values. One patient died before day 5, no other worsening heart failure episodes occurred. Two patients (14%) developed acute kidney injury but their VDP and RI were normal and did not change. Three patients (21%) did not improve their BNP (decrease >30%) but this was not associated with VDP or RI changes. Elevated derived pulmonary artery systolic pressure (>40 mmHg) was present in 6 out of 8 patients (75%) with M or B VDP and in all 4 patients with both elevated RI and M or B VDP.
Venous Pattern Day 1 Day 3 Day 5 Continous 2 8 5 Pulsatile 4 2 4 Biphasic 2 1 2 Monophasic 6 3 2 Arterial RI >0.8 8 6 4 BNP, pg/ml 1060±1180* 372±281* 424±213* Creatinine, mg/dl 1.4±0.6 1.5±0.6 1.3±0.6 Hb, g/dl 12.1±2.3 12.3±3.6 13.2±2.3 *p>0.05.
Conclusions
This is the first study exploring changes in renal hemodynamic by echo Doppler during AHF. With respect to previous studies among stable patients, our preliminary data shows a higher proportion of deranged renal venous and/or arterial pattern. After diuretic therapy a trend towards improvement in VDP was recorded. No clear association with other clinical and hemodynamic parameters seems evident.

Abstract
INTRODUCTION Resistant arterial hypertension (RHT) is defined as poor controlled blood pressure (BP) despite optimal doses of three or more antihypertensive agents, including a diuretic. In the development of RHT, hyperactivity of sympathetic (SNS) and renin-angiotensin-aldosterone (SRAA) systems are involved, and SNS is a potent stimulator of vasoactive endothelin-1 (ET-1) peptide. Renal sympathetic denervation (RSD) through disrupting renal afferent and efferent nerves attenuates SNS activity. MATERIAL AND METHODS We carried out pilot study investigating the effect of RSD on BP and plasma ET-1 levels in consecutive 9 RHT patients (7 male and 2 female, mean age of 56 ± 13.3). RESULTS After 12 months of the RSD, we observed a significant reduction of BP office, 24-h ambulatory BP monitoring (ABPM) (p < 0.05, respectively), and "non-dipping" pattern (from 55% to 35%) (p < 0.05). Moreover, RSD significantly decreased plasma ET-1 levels in both renal artery (at right from 21.8 ± 4.1 to 16.8 ± 2.9 pg/ml; p = 0.004; at left from 22.1 ± 3.7 to 18.9 ± 3.3 pg/ml; p = 0.02). We observed positive correlations between plasma renal arteries ET-1 levels and systolic BP values at ABPM [Global-SBP (r = 0.58; p < 0.01), Diurnal-SBP (r = 0.51; p < 0.03) and Nocturnal-SBP (r = 0.58; p < 0.01), respectively]. DISCUSSION Our data confirmed the positive effects of RSD on BP values in patients with RHT, and showed a possible physio-pathological role of ET-1. KEY MESSAGES RSD is associated to a significant reduction of plasma ET-1 levels, representing an useful tool into reduction of BP in RHT patients.

Abstract
Primary aldosteronism (PA) is one of the most frequent forms of secondary hypertension, associated with atherosclerosis and higher risk of cardiovascular events. Platelets play a key role in the atherosclerotic process. The aim of the study was to evaluate the platelet activation by measuring serum levels of soluble CD40L (sCD40L) and P-selectin (sP-selectin) in consecutive PA patients [subgroup: aldosterone-secreting adrenal adenoma (APA) and bilateral adrenal hyperplasia (IHA)], matched with essential hypertensive (EH) patients. The subgroup of APA patients was revaluated 6-months after unilateral adrenalectomy. In all PA group, we measured higher serum levels of both sP-selectin (14.29±9.33 pg/ml) and sCD40L (9.53±4.2 ng/ml) compared to EH patients (9.39±5.3 pg/ml and 3.54±0.94 ng/ml, respectively; p<0.001). After removal of APA, PA patients showed significant reduction of blood pressure (BP) values, plasma aldosterone (PAC) levels and ARR-ratio, associated with a significant reduction of sP-selectin (16.74±8.9 pg/ml vs. 8.1±3.8 pg/ml; p<0.01) and sCD40L (8.6±1 ng/ml vs. 5.24±0.94 ng/ml; p<0.001). In PA patients, we found a significant correlation between sP-selectin and sCD40L with PAC (r=0.52, p<0.01; r=0.50, p<0.01, respectively); this correlation was stronger in APA patients (r=0.54; p<0.01 r=0.63; p<0.01, respectively). Our results showed that PA is related to platelet activation, expressed as higher plasma values of sCD40L and sP-selectin values. Surgical treatment and consequent normalization of aldosterone secretion was associated with significant reduction of sCD40L and sP-selectin values in APA patients.

Abstract
UNLABELLED CASE BACKGROUND: Ascites appears mainly as a consequence of portal hypertension in patients with liver cirrhosis, or can be caused by several other causes, such us congestive heart failure, peritoneal malignancy, or tuberculosis. In some cases, ascites can pose a diagnostic challenge for clinicians and in some patients, despite thorough and extensive work-up, the origin of this ascites remains unknown. CASE REPORT In the unusual case hereby reported, a 52-year-old man developed severe ascites in a few weeks, in the absence of known liver disease or congestive hearth failure. We performed laboratory analysis, endoscopic, and imaging investigations, including abdominal contrast-enhanced computed tomography and 18-fluorodeoxyglucose-positron emission tomography. Peritoneal fluid analysis showed exudative fluid without neoplastic cells. A diagnostic laparoscopy with multiple diagnostic biopsies was carried out, but no macroscopic cause of the ascites was found; histopathological examination showed minimal aspects of diffuse and non-specific chronic inflammation. CONCLUSIONS We decided to empirically treat the patient with steroid therapy (methylprednisolone: 0·5 mg/kg/day). Over a period of 6 weeks, his ascites resolved and at 2 months, he was in remission on low-dose methylprednisolone. Our final hypothesis was reactive inflammatory ascites. The literature on ascites and its management has also been reviewed.

Abstract
PURPOSE To assess the impact of different vascular patterns at contrast-enhanced ultrasound (CEUS) on the characterization of small liver nodules (10-30 mm) in cirrhosis and to determine whether primary nodules and recurrent nodules (after a previously treated hepatocellular carcinoma) display variations in enhancement pattern. MATERIALS AND METHODS A total of 135 cirrhotic patients were evaluated. A diagnosis of hepatocellular carcinoma (HCC) was established according to AASLD Guidelines, based on imaging (computed tomography and/or magnetic resonance) or liver biopsy. All patients underwent CEUS. Different CEUS patterns were evaluated in terms of diagnostic accuracy: HYPER-HYPO: Arterial hyperenhancement followed by washout (hypoechoic appearance compared with surrounding parenchyma) in late phase; HYPER-ISO: Arterial hyperenhancement followed by isoenhancement (isoechoic appearance) in late phase; ISO-ISO: Isoenhancement in all vascular phases. RESULTS A total of 155 consecutive primary (n = 90) or recurrent (n = 65) nodules were detected. HCC was diagnosed in 127 nodules (71 primary, 56 recurrent). A characteristic HYPER-HYPO CEUS pattern was revealed in 52/127 (40.9%) HCCs (31 primary, 21 recurrent) giving a positive predictive value (PPV) of 98% (97% primary, 100% recurrent) and an accuracy of 51% (54% primary, 46% recurrent). A HYPER-ISO pattern was noted in 46 HCCs (31 primary, 15 recurrent). Assuming this pattern to also be indicative of HCC, the PPV and accuracy were 94% (93% primary, 97% recurrent) and 77% (84% primary, 68% recurrent), respectively. An ISO-ISO pattern was present in 29 HCCs (9 primary, 20 recurrent) and 22 non-HCCs (14 primary, 8 recurrent). CONCLUSION These data confirm that the HYPER-HYPO pattern at CEUS is definitely diagnostic for HCC in cirrhosis and that the HYPER-ISO pattern has a similar PPV, indicating that this pattern is highly suspicious for HCC. The ISO-ISO pattern was found in > 50% of recurrent nodules and indicates a high risk of HCC.

Abstract
BACKGROUND Gadoxetic acid (Gd-EOB-DTPA) is a 'hepatocyte-specific' contrast agent for magnetic resonance (MR) in both the vascular and the hepatobiliary phases. AIM To evaluate the contribution of the hepatobiliary phase of Gd-EOB-DTPA MR in the diagnosis of small hepatocellular carcinoma (HCC) in cirrhotic patients under surveillance. METHODS Between 2008 and 2011, 48 consecutive small (10-30 mm) liver nodules were detected in 33 patients, who prospectively underwent contrast-enhanced ultrasound (CEUS), Gd-EOB-DTPA-enhanced MR and helical-computed tomography (CT) in a blind study. The diagnosis of HCC was established according to AASLD 2005 criteria. RESULTS Of the 48 nodules, 38 (79%) were diagnosed as HCC, 24 (63%) of them based on AASLD non-invasive criteria, 11 diagnosed at histology and 3 during follow-up. The typical vascular pattern (arterial hypervascularisation and venous/late washout) was detected in 30 (79%) HCC nodules by MR, in 22 (58%) by CT and in 17 (45%) by CEUS. Hypointensity during the MR hepatobiliary phase was observed in all HCC nodules and in 3 nonmalignant nodules (sensitivity 100%, specificity 70%, positive predictive value 93%, negative predictive value 100%, positive likelihood ratio 3.33, negative likelihood ratio 0). Eight (21%) of the 38 HCC nodules, 7 of which lacked the typical vascular features at any of the imaging modalities, showed washout in the portal/venous phase and hypointensity in the hepatobiliary phase at MRI, while this pattern was not detected in any nonmalignant lesion. CONCLUSIONS Gadoxetic acid magnetic resonance may enhance the sensitivity of the non-invasive diagnosis of small hepatocellular carcinoma nodules in cirrhotic patients under surveillance. Double hypointensity in the portal/venous and hepatobiliary phases could be considered a new magnetic resonance pattern, highly suggestive of hypovascular hepatocellular carcinoma.

Abstract
BACKGROUND & AIMS Aim of the study was to assess the clinical impact of conventional transarterial chemoembolization (cTACE) repeated "on demand" on HCC outcome. Outcome measures were: response rate to first and repeated cTACE, recurrence rates and overall survival. METHODS The outcome of 151 consecutive HCC patients submitted to a first cTACE from January 2004 to December 2005 was retrospectively analyzed. RESULTS Complete radiological response (CR) was observed in 72/151 (48%), 34/60 (52%) and 12/22 (55%) patients after first, second and third cTACE, respectively. Recurrence rates at 6 and 12months were 37% and 61% after the first cTACE, and 40% and 59% after the second cTACE, respectively. Patients not achieving CR or with a recurrence after CR not treated with curative therapies were 94 and 84 after first and second cTACE, respectively. Of these, 60/94 (64%) and 22/84 (26%) were submitted to a second and third cTACE, respectively. Median overall survival was 32.0months but 25.0months excluding transplanted patients. Factors at the time of first cTACE associated with overall shorter survival at multivariate analysis were higher bilirubin, higher AFP and not achieving CR. CONCLUSIONS CR and recurrence rates after first and second cTACE were similar. About 64% of patients were submitted to second cTACE, while only few patients (26%) were submitted to third cTACE using an "on demand" policy. These figures may be also useful for planning trials for the evaluation of the efficacy of repeated TACE vs. TACE combined with adjuvant treatments or vs. systemic treatments.

Abstract
15604 Background: Sorafenib is an oral multitargeted tyrosine kinase inhibitor of RAF-kinase and VEGFR2, with antiangiogenic and antitumor activity in pretreated advanced renal cell cancer (RCC). Methods: In our institution, from December 2005 to November 2006, 131 consecutive patients(pts) with advanced RCC received sorafenib 400mg/bid/continuously. Main patient characteristics were: clear-cell cancer 106 pts, papillary-cell 15 pts, cromophobe-cell 3pts, collecting duct carcinoma 3pts, other histotypes 4pts. Previous nephrectomy was performed in 122 pts with median relapse free survival of 23 months (range 3–180 mos). The most common site of disease was lung, whereas 94 pts had 2 or more secondary disease locations. According to Motzer’s prognostic score 85 pts were at low risk, 36 pts and 10 pts at intermediate and high risk respectively . 12 pts were treatment naïve for metastatic disease. 68 and 51pts received one or at least two systemic treatments respectively. Results: Currently, 106 pts are evaluable for safety and objective response. According to the RECIST criteria, the activity of sorafenib in terms of tumor shrinkage was observed in 32 pts(31%) with 10 partial response (9.5%) and 22 minor response (21%) respectively. Stable disease was seen in 42 pts (41%) and progressive disease in 28 pts (26%), 4 pts were not evaluable for response. Overall, 74 pts (72%) had disease growth control. Median duration of response was 8 months and median time to progression was 6.5 mos, median overall survival has not been reached yet. The most common treatment-emergent adverse effects seen in 78% of pts, were grade (G) 1/2 (NCI-CTC) and included hand foot syndrome, rash, diarrhea, fatigue, hypertension and mucositis. Dose modification due to G3–4 adverse event, such as skin toxicity and cardiovascular events, was performed in 35 pts(32%). Conclusion: sorafenib is effective in terms of tumor growth control in untreated as well as in pretreated patients and in different hystotypes of renal cell cancer. Particularly, in heavily pretreated patients the number and severity of drug related toxicity suggests the dose reduction as possible standard therapy.

Abstract
Gamma-ray bursts (GRBs) fall into two classes: short-hard and long-soft bursts. The latter are now known to have X-ray and optical afterglows, to occur at cosmological distances in star-forming galaxies, and to be associated with the explosion of massive stars. In contrast, the distance scale, the energy scale and the progenitors of the short bursts have remained a mystery. Here we report the discovery of a short-hard burst whose accurate localization has led to follow-up observations that have identified the X-ray afterglow and (for the first time) the optical afterglow of a short-hard burst; this in turn led to the identification of the host galaxy of the burst as a late-type galaxy at z = 0.16 (ref. 10). These results show that at least some short-hard bursts occur at cosmological distances in the outskirts of galaxies, and are likely to be caused by the merging of compact binaries.

Abstract
The prompt optical emission that arrives with the gamma-rays from a cosmic gamma-ray burst (GRB) is a signature of the engine powering the burst, the properties of the ultra-relativistic ejecta of the explosion, and the ejecta's interactions with the surroundings. Until now, only GRB 990123 had been detected at optical wavelengths during the burst phase. Its prompt optical emission was variable and uncorrelated with the prompt gamma-ray emission, suggesting that the optical emission was generated by a reverse shock arising from the ejecta's collision with surrounding material. Here we report prompt optical emission from GRB 041219a. It is variable and correlated with the prompt gamma-rays, indicating a common origin for the optical light and the gamma-rays. Within the context of the standard fireball model of GRBs, we attribute this new optical component to internal shocks driven into the burst ejecta by variations of the inner engine. The correlated optical emission is a direct probe of the jet isolated from the medium. The timing of the uncorrelated optical emission is strongly dependent on the nature of the medium.
