Abstract
BACKGROUND AND AIMS The effect of surgical treatment for spontaneous intracerebral hemorrhage (ICH) remains uncertain. We conducted an observational retrospective cohort study on supra-centimeter spontaneous ICH treated with either neurosurgical or conservative management. The baseline demographics and risk factors were correlated with in-hospital mortality and 3 and 6-month survival rates stratified by management. METHODS We included all patients with evidence of spontaneous ICH > 1 cm detected by CT and admitted between august 2020 and march 2021 to the "SMM" Hospital in Perugia. RESULTS Onehundredandtwentytwo patients were included in the study, and 45% (n.55) were surgically treated. The mean age was 71.9 ± 15.3, and 61% (n.75) were males. Intra-hospital mortality ended up being 31% (n.38), 3 months-survival was 63% (n.77) and 6 months-survival was 60% (n.73). From the multivariate analysis of the surgical patients versus medical patient, we observed that the surgical patients were younger (67.5 ± 14.9 vs 75.5 ± 14.7 y; OR 0.87; Cl 95% 0.85-0.94; p 0.001), with greater ICH volume at the onset (61 ± 39.4 cc vs 51 ± 64 cc; OR 1.03; Cl 95% 1.005-1.07; p 0.05), more midline shift (7.61 ± 5.54 mm vs 4.09 ± 5.88 mm; OR 1.37; Cl 95% 1.045-1.79; p 0.023), and a higher ICH score (3 vs 2 mean ICH score; OR 21.12; Cl 95% 2.6-170.6; p 0.004). Intra-hospital mortality in the surgical group and in the conservative treatment group was respectively 33% vs 30%, 3 month-survival was 64% vs 63% and 6 month- survival were 60% in both groups. CONCLUSIONS Our patient cohort shows no overall benefit from surgery over conservative treatment, but surgical patients were younger and had larger ICH volume.

Abstract
PURPOSE Brain metastases rarely complicate the natural history of patients with adrenocortical carcinoma (ACC). No information is available regarding the life expectancy and efficacy of treatments in ACC patients with brain involvement. METHODS A pooled analysis was performed by searching on PubMed and using the keywords: "brain metastases in adrenocortical carcinoma", and "leptomeningeal metastases in adrenocortical carcinoma". Four patients diagnosed at Spedali Civili Hospital in Brescia were added to the analysis. Data concerning demographic, disease characteristics, adopted treatments and patient prognosis were collected. RESULTS A total of 27 patients (18 adults and 9 children) were included in this study, 22 of them had an adequate follow-up. Brain metastases occurred late in the natural history of adult patients but not in that of children. Surgery plus/minus radiation therapy was the treatment of choice. Adult patients with brain metastases had a poor prognosis with a median progression-free survival (PFS) and overall survival (OS) of 2 and 7 months, respectively. Median PFS and OS were not attained in children. CONCLUSION Brain metastases in ACC patients are rare and are associated with poor prognosis, particularly in adults. Surgery plus/minus radiotherapy is the only therapeutic approach that can offer patients a chance to obtain durable local disease control.

Abstract
The achievement of a proper circumferential decompression of the sac instead of simple posterior bilateral laminectomy has been progressively highlighted. Since the majority of spinal cord compression involves firstly the ventral part of the sac, circumferential and anterior decompression are associated with better neurological outcomes at discharge and at follow-up, and should be achieved in case of circumferential or anterior/anterolateral compression. Post-operative improvement and/or maintenance of ambulation resulted to be a significative protective factor at last follow-up.
Introduction The impact of neurological deficits plays a role of inestimable importance in patients with a neoplastic disease. The role of surgery for the management of symptomatic spinal cord compression (SSCC) cannot be overemphasized, as surgery represents often the first and paramount step in patients presenting with motor deficits. The traditional paradigm of simple bilateral laminectomy for the treatment of spinal cord compression has been reviewed. The need to achieve a proper circumferential decompression of the spinal sac has been progressively highlighted in combination with the development of the more comprehensive and multidisciplinary concept of separation surgery. Objective The aim of this paper is to analyze different strategies of decompression, while evaluating whether circumferential/anterior decompression is able to guarantee a better control and restoration of neurological functions in patients with motor impairment, if compared to traditional posterior decompression. Materials and methods This is a retrospective observational study investigating symptomatic patients that underwent surgical treatment for spinal metastases at author’s Institutions from January 2010 to June 2019. Data recorded concerned patient demographics, tumor histology, peri-operative and follow-up neurological status (ASIA), ambulation ability, stability (SINS), grade (ESCC) and source of epidural compression and type of decompression (anterior/anterior-lateral (AD); posterior/posterior-lateral (PD/PDL); circumferential (CD)). Results A total number of 84 patients was included. AD/CD patients showed higher chance of neurological improvement and reduced rates of worsening compared to PD/PLD group (94.1%/100% vs 60.4%; 11.8% vs 45.8% respectively). Univariate logistic regression identified immediate post-operative improvement to be a significative protective factor for worsening at last follow-up. Stratifying patients for site of compression and considering anterior and circumferential groups, immediate post-operative neurological improvement, was mostly associated with AD and CD (p 0.011 and 0.025 respectively). Walking at last follow up was influenced by post-operative maintenance of ambulation (p 0.001). Conclusion The necessity to remove the epidural metastatic compression from its source should be considered of paramount importance. Since the majority of spinal cord compression involves firstly the ventral part of the sac, CD/AD are associated with better neurological outcomes and should be achieved in case of circumferential or anterior/anterolateral compression.

Abstract
OBJECTIVE To optimize the management of patients with chronic hepatitis C virus (HCV). MATERIALS AND METHODS We developed two questionnaires to determine Italian healthcare professionals' opinions on the overall management of HCV chronic liver disease and the use of direct-acting antivirals (DAAs) in the treatment of HCV. A Delphi consensus method using the RAND/UCLA appropriateness method was used to determine opinions of an expert panel (EP) of specialists. RESULTS Overall 443 physicians from 167 Italian centres completed the two questionnaires. The EP confirmed the importance of collaboration with general practitioners (GPs) and HCV testing in high-risk groups, but did not agree on treating patients over 80 years of age with DAAs. Over 90% agreed that it was important to quantify HCV-RNA, determine genotype, and test for anti-HIV and HBsAg before starting DAAs. Transient elastography (FibroScan®) was used by >90% to evaluate the stage of liver fibrosis while serum biomarkers were used by <20%. Adherence to therapy, drug-drug interactions and the possibility of treating advanced liver disease were decisive factors in therapy choice. Monthly monitoring during therapy was considered appropriate and 80% were in favor of HCV-RNA testing 24 weeks after the end of the therapy to confirm sustained virological response (SVR). Over 80% agreed that it was necessary to continue follow-up of patients with advanced fibrosis/cirrhosis. CONCLUSIONS Scientific organizations should review their guideline recommendations to facilitate access to DAAs.

Abstract
BACKGROUND The aim of the study was to evaluate the use of enamel matrix derivative (EMD) alone or in association with deproteinized bovine bone mineral (DBBM) for the treatment of partially contained intrabony defects. METHODS A total of 20 two-walled intrabony defects belonging to nine patients were included. Ten defects were treated with EMD alone (test group 1) and the other 10 were treated with EMD and DBBM (test group 2), applying either modified papilla preservation technique or simplified papilla preservation technique. RESULTS Twelve months after surgery, in the test group 1, PD was 2.8 ± 0.8 mm, REC was 2.3 ± 2.4 mm and CAL was 5.0 ± 2.8 mm, significantly reduced from baseline values (P < 0.05). Likewise, in test group 2, PD, REC and CAL reduced to 3.0 ± 0.7 mm, 3.9 ± 1.5 mm and 6.9 ± 1.1 mm respectively, from baseline values at 12 months (P < 0.05). No significant differences between groups were found. CONCLUSIONS The results showed that the use of EMD alone and the use of a combination of EMD and DBBM for the treatment of partially contained defects showed comparable clinical and radiographic outcomes after 12 months.

Abstract
Leishmania infections are endemic in dogs in central and southern regions of Italy while feline leishmaniosis has only been sporadically described in these areas and few studies have been reported on serological and molecular investigation of infections in domestic cats. The purpose of this study is to assess the presence of Leishmania infantum infection in cats from Sardinia, a typical endemic area of leishmaniasis in Italy. Ninety cats attended at the Veterinary Teaching Hospital of the University of Sassari, Italy, were tested for L. infantum using the indirect immunofluorescent antibody (IFA) test and PCR. Serological (10%) and molecular (5.5%) detection in this population was low, with antibody titres ranging from 1/40 to 1/80. Only one cat was simultaneously positive by IFAT and PCR. This study shows the presence of L. infantum infection in cats living in Sardinia, with a prevalence that falls within the ranges described in other endemic areas and confirms the need of further research to better characterize the epidemiologic role of cats in the transmission of this infection.

Abstract
The validity of the clinical staging of Jaksic and Vitale for chronic lymphocytic leukemia (CLL), designated total tumor mass score (TTM), was tested in 130 consecutive and previously untreated patients followed at our institution over a 15-year period. The analysis, extended to the whole population, confirmed the prognostic value of the TTM score. Patients with a high TTM (> 9.0) had an expected median survival (EMS) of 30 months; those with a low TTM (< 8.9) had an EMS of 129 months (P < 0.001). The prognostic value of TTM remained even after adjustment was made for age, sex, lymphocyte count, TTM distribution pattern, bone marrow failure, and response to therapy. Taking into account the value of the TTM score, patients of the intermediate risk group (stage II of Rai et al.) could be divided into two subgroups with a different prognosis (EMS 200 vs. 32 months; P < 0.005). When used as a continuous quantitative parameter the TTM score may help to define response to therapy. In this study TTM response to therapy was significant for prognosis (P < 0.001), and there seems to be relationship between the degree of response and survival probability.

Abstract
One hundred patients with chronic lymphocytic leukemia (CLL) followed in our department between November 1969 and December 1982 were reviewed and classified according to the staging system proposed by the International Workshop on CLL (IWCLL). Analysis of actuarial survival curves revealed a significant chisquare value for heterogeneity and trend. In addition, thrombocytopenia and anemia appeared to be the most important risk factors. A large variability in the course of disease, not well explained by the staging system of the IWCLL, was found among the nonanemic and nonthrombopenic patients. Analysis of A and B stage patients according to absolute peripheral blood lymphocytosis (less or more than 50 × 109/liter) showed two separate patterns of survival.

Abstract
Quantum statistics have a profound impact on the properties of systems composed of identical particles. At the most elementary level, Bose and Fermi quantum statistics differ in the exchange phase, either 0 or π, which the wave function acquires when two identical particles are exchanged. In this Letter, we demonstrate that the exchange phase can be directly probed with a pair of massive particles by physically exchanging their positions. We present two protocols where the particles always remain spatially well separated, thus ensuring that the exchange contribution to their interaction energy is negligible and that the detected signal can only be attributed to the exchange symmetry of the wave function. We discuss possible implementations with a pair of trapped atoms or ions.

Abstract
One hundred and sixty-three consecutive patients (129 females and 34 males) over 60 years of age attending the Headache Centre of the University of Perugia in the period January 2000-December 2001 were included in the study. One hundred and fifty-two (93.3%) were affected by a primary headache disorder. According to the 1988 IHS Criteria, their prevailing attacks could be diagnosed as migraine without aura (MwoA) in 57.2% of cases ( n = 87) and as migraine with aura (MwA) in 11.8% of cases ( n = 18). Attacks both in MwoA and MwA were unilateral and of severe-to-moderate intensity in 45% and 50% of cases. Head pain was referred as pulsating by 56% and 38.9% of MwoA patients MwA patients, respectively. Aggravation with routine daily activities was present in 72.4% and 61.1% in MwoA and MwA patient groups. The most frequent accompanying symptoms were photophobia and phonophobia. Headache attacks were of shorter duration in MwA patients, but in 3.4% of MwoA patients attacks lasted between 2 and 4 h. Of patients affected by MwA, 55% referred, together with the typical attacks, symptoms of aura not followed by headache. A worsening of headache in the last 5 years was reported by 67.8% and 44.4% of MwoA and MwA patients, respectively. Of the patients with MwoA, 86.2% ( n = 75), and 83.3% ( n = 15) of those with MwA used symptomatic drugs for their attacks. In the majority of cases they took more than one analgesic or non steroidal anti-inflammatory drug. A total of 51.7% of patients with MwoA and 55.5% of patients with MwA were under prophylactic treatment. Preventive drugs included antidepressants, beta-blockers, calcium channel antagonists and antiepileptic drugs. The choice of symptomatic or prophylactic drugs was made, in the majority of cases, on the basis of concomitant diseases.

Abstract
The occurrence of liver disease and its relation to HBV markers were investigated in ten children with AML who were given HDARAC as late consolidation therapy. None of them developed jaundice or biochemical evidence of cholestasis. During therapy, SGPT values were normal in 5/10 patients, while in the other 5 a sharp increase was noted. These enzyme elevations followed an unusual timing, peaking just before each infusion of HDARAC. Evidence of long-lasting hepatocellular necrosis after therapy withdrawal was found in 8/8 cases. One child died of fulminant type B hepatitis and HBsAg positivity was found in 2/10 patients during therapy and 3/8 after withdrawal of the drug. Three children developed HBV antibodies during the observation period. We conclude that the use of HDARAC in childhood leukemia is not associated with major evidence of direct drug hepatotoxicity while it clearly affects the natural outcome of viral hepatitis.

Abstract
The present study was aimed at verifying the clinical characteristics of a typical attack in 20 migraine patients, 10 responders and 10 non-responders to rizatriptan, and at investigating any differences in the levels of neuropeptides of the trigeminovascular or parasympathetic systems [calcitonin gene-related peptide (CGRP), neurokinin A (NKA) and vasoactive intestinal peptide (VIP) measured by radio-immunoassay methods in external jugular blood] between responders and nonresponders. In all responders to rizatriptan, pain was unilateral, severe, and pulsating, and in five of them at least one sign suggestive of parasympathetic system activation was recorded. Five patients who were non-responders to rizatriptan referred bilateral and non-pulsating pain, even though severe in most of them. CGRP and NKA levels measured before rizatriptan administration were significantly higher in responders than in non-responders ( P < 0.0001 and P < 0.002, respectively). In the five patients with autonomic signs among rizatriptan responders, detectable VIP levels were found at baseline. One hour after rizatriptan administration, a decrease in CGRP and NKA levels was evident in the external jugular venous blood of rizatriptan responders, and this corresponded to a significant pain relief and alleviation of accompanying symptoms. VIP levels were also significantly reduced at the same time in the five patients with autonomic signs. After rizatriptan administration, CGRP and NKA levels in non-responder patients showed less significant variations at all time points after rizatriptan administration compared with rizatriptan responders. The present study, although carried out on a limited number of patients, supports recent clinical evidence of increased trigeminal activation associated with a better triptan response in migraine patients accompanied by parasympathetic activation in a subgroup of patients with autonomic signs. In contrast, the poor response seems to be correlated with a lesser degree of trigeminal activation, lower variations of trigeminal neuropeptides after triptan administration, and no evidence of parasympathetic activation at baseline.

Abstract
The aim of the present study was to verify cerebrospinal fluid (CSF) levels of glial cell line-derived neurotrophic factor (GDNF) and somatostatin, both measured by sensitive immunoassay, in: 16 chronic migraine (CM) patients, 15 patients with an antecedent history of migraine without aura diagnosed as having probable chronic migraine (PCM) and probable analgesic-abuse headache (PAAH), 20 patients affected by primary fibromyalgia syndrome (PFMS), and 20 control subjects. Significantly lower levels of GDNF and somatostatin were found in the CSF of both CM and PCM + PAAH patients compared with controls (GDNF = P < 0.001, P < 0.002; somatostatin = P < 0.002, P < 0.0003), without significant difference between the two groups. PFMS patients, with and without analgesic abuse, also had significantly lower levels of both somatostatin and GDNF ( P < 0.0002, P < 0.001), which did not differ from those of CM and PCM + PAAH patients. A significant positive correlation emerged between CSF values of GDNF and those of somatostatin in CM ( r = 0.70, P < 0.02), PCM + PAAH ( r = 0.78, P < 0.004), and PFMS patients ( r = 0.68, P < 0.008). Based on experimental findings, it can be postulated that reduced CSF levels of GDNF and somatostatin in both CM and PCM + PAAH patients can contribute to sustained central sensitization underlying chronic head pain. The abuse of simple or combination analgesics does not seem to influence the biochemical changes investigated, which appear to be more strictly related to the chronic pain state, as demonstrated also for fibromyalgia.

Abstract
OBJECTIVE By-the-book implementation of non-invasive prenatal test and clinical validation for trisomy 21. STUDY DESIGN Publicly funded prospective study of 225 cases. Women at risk for trisomy 21 > 1/250 based on combined ultrasound and serum markers during first or second trimester were eligible following an informed consent. The technique was established from the available literature and performed on 10 mL of venous blood collected prior to chorionic villus sampling or amniocentesis. Investigators were blinded to the fetal karyotype. Results were expressed in Z-scores of the percentage of each chromosome. RESULTS Among 976 eligible cases, 225 were processed: 8 were used for pretesting phase and 23 to build a reference set. One hundred thirty six euploid cases and 47 with trisomy 21 were then run randomly. Eleven cases yielded no result (4.8%). Z-scores were above 3 (7.58+/-2.41) for chromosome 21 in all 47 trisomies and in none of the euploid cases (0.11+/-1.0). Z-scores were within normal range for the other chromosomes in both groups. Using a cut-off of 3, sensitivity and specificity were of 100% 95% CI [94.1, 100] and 100% 95% CI [98, 100], respectively. CONCLUSION Non-invasive prenatal test for trisomy 21 is a robust strategy that can be translated from seminal publications. Publicly funded studies should refine its indications and cost-effectiveness in prenatal screening and diagnosis. © 2015 John Wiley & Sons, Ltd.

Abstract
Alisporivir (ALV) is an oral, investigational host-targeting agent, with pangenotypic activity against hepatitis C virus (HCV). This randomized, double-blind, placebo-controlled, Phase II study explored the efficacy and safety of ALV with peginterferon-α2a/ribavirin (PR) in patients with chronic HCV genotype 1 infection in whom prior PR had failed (43% relapsers, 34% null responders and 23% partial responders). Four-hundred-and-fifty-nine patients were randomized (1:1:1:1) to ALV 600 mg once daily (QD), ALV 800 mg QD, ALV 400 twice daily (BID) or placebo plus PR for 48 weeks. When the global ALV trial programme was put on clinical hold, all patients in this study had received ≥31 weeks of randomized treatment; patients completed 48 weeks on PR alone. All ALV groups demonstrated superior rates of complete early virologic response (cEVR; primary endpoint) vs PR alone (P ≤ 0.0131), with highest cEVR rate seen with ALV 400 mg BID (74% vs 36% with PR alone; P < 0.0001). Respective SVR12 rates (key secondary endpoint) were 65% vs 26% in prior relapsers, 63% vs 5% in partial responders and 68% vs 3% in null responders. In patients who received >40 weeks of randomized treatment, the SVR12 rate was 89% for ALV 400 mg BID vs 30% for PR alone (P = 0.0053). Rates of viral breakthrough and relapse were lowest with ALV 400 mg BID. One case of pancreatitis (fully recovered) occurred with ALV/PR. Common AEs were headache, fatigue, anaemia, neutropenia and nausea. Hypertension was infrequent, but more common with ALV. ALV merits further investigation in interferon-free regimens in combination with direct-acting antiviral agents.

Abstract
We implemented a low-temperature approach to fabricate efficient photoanodes for dye-sensitized solar cells, which combines three different nanoarchitectures, namely, a highly conductive and highly transparent AZO film, a thin TiO2-blocking layer, and a mesoporous TiO2 nanorod-based working electrode. All the components were processed at T≤200°C. Both the AZO and the TiO2 blocking layers were deposited by reactive sputtering, whereas the TiO2 nanorods were synthesized by surfactant-assisted wet-chemical routes and processed into photoelectrodes in which the native geometric features assured uniform mesoporous structure with effective nanocrystal interconnectivity suitable to maximize light harvesting and electron diffusion. Because of the optimized structure of the TiO2-blocking/AZO bilayer, and thanks to the good adhesion of the TiO2 nanorods over it, a significant enhancement of the charge recombination resistance was demonstrated, this laying on the basis of the outstanding power conversion efficiency achievable through the use of this photoanode's architecture: a value of 4.6% (N719) was achieved with a 4-μm-thick electrode processed at T=200°C. This value noticeably overcomes the current literature limit got on AZO-based cells (N719), which instead use Nb-doped and thicker blocking layers, and thicker nanostructured photoanodes, which have been even sintered at higher temperatures (450-500°C).

Abstract
Human epidermal growth factor receptor 2 (HER2) is involved in the malignant progression of several human cancers, including esophageal adenocarcinoma (EAC). The purpose of this study was to evaluate HER2 overexpression and to explore the feasibility of confocal laser endomicroscopy for in vivo molecular imaging of HER2 status in an animal model of Barrett's-related EAC. Rats underwent esophagojejunostomy with gastric preservation. At 30 weeks post-surgery, the esophagus of 46 rats was studied; endoscopic and histological findings were correlated with HER2 immunofluorescence on excised biopsies and gross specimens. At this age, 23/46 rats developed Barrett's esophagus (BE), and 6/46 had cancer (four EAC and two squamous cell carcinomas). A significant overexpression of HER2 was observed in esophageal adenocarcinoma compared with normal squamous esophagus (9.4-fold) and BE (6.0-fold). AKT and its phosphorylated form were also overexpressed in cancer areas. Molecular imaging was performed at 80 weeks post-surgery in four rats after tail injection of fluorescent-labeled anti-HER2 antibody. At this age, 3/4 rats developed advance adenocarcinoma and showed in vivo overexpression of HER2 by molecular confocal laser endomicroscopy with heterogeneous distribution within cancer; no HER2 signal was observed in normal or Barrett's tissues. Therefore, HER2 overexpression is a typical feature of the surgical induced model of EAC that can be easily quantified in vivo using an innovative mini-invasive approach including confocal endomicroscopy; this approach may avoid limits of histological evaluation of HER2 status on 'blinded' biopsies.

Abstract
We detected a novel papillomavirus (EaPV1) from healthy skin and from sun associated cutaneous lesions of an Asinara (Sardinia, Italy) white donkey reared in captivity in a wildlife recovery centre. The entire genome of EaPV1 was cloned, sequenced, and characterised. Genome is 7467 bp long, and shows some characteristic elements of horse papillomaviruses, including a small untranslated region between the early and late regions and the lack of the retinoblastoma tumour suppressor binding domain LXCXE in E7. Additionally, a typical E6 ORF is missing. EaPV1 DNA was detected in low copies in normal skin of white and grey donkeys of the Asinara Island, and does not transform rodent fibroblasts in standard transformation assays. Pairwise nucleotide alignments and phylogenetic analyses based on concatenated E1-E2-L1 amino acid sequences revealed the highest similarity with the Equine papillomavirus type 1. The discovery of EaPV1, the prototype of a novel genus and the first papillomavirus isolated in donkeys, confirms a broad diversity in Equidae papillomaviruses. Taken together, data suggest that EaPV1 is a non-malignant papillomavirus adapted to healthy skin of donkeys.

Abstract
We assessed, in real-life practice, viral, demographic, genetic and metabolic factors influencing the sustained virologic response (SVR), with a gender-oriented analysis, in patients with chronic hepatitis C virus (HCV) treated with pegylated interferon and ribavirin. Six hundred and seventy naïve patients were treated with dual therapy and evaluated by gender and HCV genotype. Associations between baseline variables and SVR were assessed by multivariate logistic regression analysis. Among 362 genotype 1 patients, SVR was achieved in 158 patients (44%), and SVR was independently associated with age less than 50 years (OR 2.12; 95% CI 1.09-4.30; P=0.039) and C/C genotype rs12979860 SNP (OR 2.83; 1.19-6.74; P=0.002) in 163 females, while absence of visceral obesity (OR 2.491; 1.131-5.487; P=0.023), HCV-RNA lower than 400,000 IU/mL (OR 2.66; 1.273-5.558; P=0.009) and C/C genotype rs12979860 SNP (OR 4.969; 2.401-10.283; P<0.001) were independently associated with SVR in 199 males. Combining favourable baseline variables, the probability of obtaining SVR ranged from 27.6% to 84.2% in females, and from 14.3% to 85.7% in males. The rate of SVR was 81.1% in 175 genotype 2 patients, and 69% in 100 genotype 3 patients. Rapid virologic response was the only valid predictor of SVR regardless of other features. In conclusions, in the setting of HCV genotype 1, chronic hepatitis, combining rapid virologic response and predictive factors, which are different for females and males, allows clinicians to single out a group of patients whose likelihood of SVR exceeds 80%. For these patients, triple therapy with first-generation protease inhibitors may be unwarranted.

Abstract
We study one-dimensional quantum walks in a homogenous electric field. The field is given by a phase which depends linearly on position and is applied after each step. The long time propagation properties of this system, such as revivals, ballistic expansion, and Anderson localization, depend very sensitively on the value of the electric field, Φ, e.g., on whether Φ/(2π) is rational or irrational. We relate these properties to the continued fraction expansion of the field. When the field is given only with finite accuracy, the beginning of the expansion allows analogous conclusions about the behavior on finite time scales.

Abstract
BACKGROUND Endovascular procedures are nowadays limited by difficulties arising from the use of 2D images and are associated with dangerous X-ray exposure and the injection of nephrotoxic contrast medium. METHODS An electromagnetic navigator is proposed to guide endovascular procedures with reduced radiation dose and contrast medium injection. Five DOF electromagnetic sensors are calibrated and used to track in real time the positions and orientation of endovascular catheters and guidewires, while intraoperative 3D rotational angiography is used to acquire 3D models of patient anatomy. A preliminary prototype is developed to prove the feasibility of the system using an anthropomorphic phantom. RESULTS The spatial accuracy of the system was evaluated during 70 targeting trials obtaining an overall accuracy of 1.2 ± 0.3 mm; system usability was positively evaluated by three surgeons. CONCLUSIONS The strategy proposed to sensorize endovascular instruments paves the way for the development of surgical strategies with reduced radiation dose and contrast medium injection. Further in vitro, animal and clinical experiments are necessary for complete surgical validation.

Abstract
Hepatic iron overload has been described in chronic hepatitis C as a cofactor affecting fibrosis progression. Data in patients with chronic hepatitis B infection are scarce. We investigated hepatic iron deposits and serum iron indices in 205 consecutive patients with hepatitis B and compensated liver disease. Mean age of the patients was 42.4 ± 12.4 years and 72.5% were males. Coinfection with hepatitis delta virus (HDV) was present in 8.8%. At least one of the serum iron indices was elevated in 41.5% of cases. Hepatic iron deposits were detected in 35.1% of patients, most of them being minimal (grade I) (59.7%) or mild (grade II) (27.8%). Variables significantly associated with hepatic iron deposits were male gender (P = 0.001), serum ferritin (P = 0.008), γGT (P = 0.05) and alkaline phosphatase (P = 0.05) levels. By multivariate analysis hepatic iron deposits correlated with serum ferritin [odds ratio (OR) 1.2, 95% confidence interval (CI) 1.05-1.4, P = 0.002]. Presence of mild-moderate (grades II and III) hepatic iron deposits could be excluded with high negative predictive value (90%) when serum ferritin was within normal values. A significant correlation between coinfection with HDV and hepatic iron deposits was also found (OR 4.23, 95% CI 1.52-11.82, P = 0.003). When compared to monoinfected cases, HDV positive patients had more elevated γGT (P = 0.03), more advanced fibrosis and more severe iron deposits (P < 0.0001). In conclusion, in well-compensated chronic hepatitis B infection, hepatic iron deposits and elevation of serum iron indices are common, especially in male gender and in patients coinfected with HDV. As HBV/HDV liver disease is generally more rapidly progressive than that caused by HBV monoinfection, we speculate that iron overload may be one of the factors contributing to the severity of liver disease.
