Abstract
INTRODUCTION Hugo Robot-Assisted Surgery (RAS) System has been conceived with enhanced modularity but its role for nephron-sparing surgery setting still remains poorly explored. We aimed to describe our experience in robot-assisted partial nephrectomy (RAPN) with a three-arms setting for the first off-clamp series using the new Hugo RAS System. METHODS Patients were placed on an extended flank position at the margin of the surgical bed with a slightly flexion (45°). The first 11 mm robotic trocar (camera port) was placed along the pararectal line 14 ± 2 cm far from the umbilicus. The pneumoperitoneum was then induced through the AirSeal system (SurgiQuest, Milford, Connecticut, USA©). Two more 8 mm operative robotic ports were placed under direct vision, either 8 ± 1 cm far from optic's port. Two 12 mm laparoscopic ports for bed-assistant were placed between robotic ports. Monopolar curved shears, fenestrated grasper, and large needle driver were used in a three-instruments configuration. RESULTS Off-clamp RAPN was successfully performed in seven patients with cT1 renal masses using a trans-peritoneal route. Median port placement and docking time was 6 min (IQR, 4-8 min). Hemostasis was achieved through renorraphy using a single transfix stitch with sliding clips technique. There was no need for additional ports placement. No intraoperative complications occurred, no clashing of robotic instruments or between the robotic arms was observed. No technical failures of the system occurred. Median console time was 83 min (IQR, 68-115 min). Median estimated blood loss were 200 ml (IQR, 50-400 ml). All patients were discharged between post-operative day 2 and 3, without the need of hospital readmission. No complications were recorded within the first 30 post-operative days. CONCLUSIONS We performed the first series of off-clamp RAPN using the novel HUGO RAS System. This novel robotic platform showed an easy-friendly docking system, providing excellent perioperative outcomes with a simple three-arms configuration.

Abstract
Identification of qualitative variants of von Willebrand disease (VWD) can be a diagnostic challenge because of discrepant results obtained in the multiple laboratory tests available for its appropriate classification. We report two cases of infrequent inherited variants of VWD with unclear preliminary results with the test panel available at the time of first consultation and that were finally diagnosed as a VWD type 2A/IID with a c.8318 G > C, p.Cys2773Ser mutation and a VWD type 2M with c.4225 T > G, p.Val1409Phe mutation, respectively. The description of these two cases highlights that despite the limited diagnostic panel for the evaluation of von Willebrand Factor (VWF) functionality, the multimeric analysis and genetic family studies were fundamental tools to achieve the final diagnosis.

Abstract
The search for Majorana bound states in solid-state physics has been limited to materials that display a gap in their bulk spectrum. We show that such unpaired states appear in certain quasi-one-dimensional Josephson-junction arrays with gapless bulk excitations. The bulk modes mediate a coupling between Majorana bound states via the Ruderman-Kittel-Yosida-Kasuya mechanism. As a consequence, the lowest energy doublet acquires a finite energy difference. For a realistic set of parameters this energy splitting remains much smaller than the energy of the bulk eigenstates even for short chains of length L∼10.

Abstract
We have developed an approach to calculate the single-particle Green function of a one-dimensional many-body system in the strongly localized limit at zero temperature. Our approach sums the contributions of all possible forward scattering paths in configuration space. We demonstrate that for fermions and nearest neighbors interactions the Green function factorizes at every link connecting two sites with the same occupation. As a consequence, the conductance distribution function for interacting systems is log-normal, in the same universality class as non-interacting systems. We have developed a numerical procedure to calculate the ground state and the Green function, generating all possible paths in configuration space. Our results agree with results obtained by exact diagonalization of small systems in the limit of large disorder.

Abstract
OBJECTIVE To assess the psychometric properties of the Italian adaptation of the Hypomania-Check-List 32-item, second revision (HCL-32-R2) for the detection of bipolarity in major depressive disorder (MDD) treatment-seeking outpatients. METHODS A back-to-back Italian adaption of the "Bipolar Disorders: Improving Diagnosis, Guidance, and Education" English module of the HCL-32-R2 was administered between March 2013 and October 2014 across twelve collaborating sites in Italy. Diagnostic and Statistical Manual Fourth edition (DSM-IV) diagnoses were made adopting the mini-international neuropsychiatric interview, using bipolar disorder (BD) patients as controls. RESULTS In our sample (n=441, of whom, BD-I=68; BD-II=117; MDD=256), using a cut-off of 14 allowed the HCL-32-R2 to discriminate DSM-IV-defined MDD patients between "true unipolar" (HCL-32-R2(-)) and "sub-threshold bipolar depression" (HCL-32-R2(+)) with sensitivity=89% and specificity=79%. Area under the curve was .888; positive and negative predictive values were 75.34% and 90.99% respectively. Owing to clinical interpretability considerations and consistency with previous adaptations of the HCL-32, a two-factor solution (F1="hyperactive/elated" vs. F2="irritable/distractible/impulsive") was preferred using exploratory and confirmatory factor analyses, whereas items n.33 ("I gamble more") and n.34 ("I eat more") introduced in the R2 version of the scale slightly loaded onto F2 and F1 respectively. Cronbach׳s α=.88 for F1 and .71 for F2. LIMITATIONS No cross-validation with any additional validated screening tool; treatment-seeking outpatient sample; recall bias; no systematic evaluation of eventual medical/psychiatric comorbidities, current/lifetime pharmacological history, neither record of severity of current MDE. CONCLUSIONS Our results seem to indicate fair accuracy of HCL-32 as a screening instrument for BD, though replication studies are warranted.

Abstract
OBJECTIVE To assess the psychometric properties of the Arabic adaptation of the Hypomania-Check-List 32-item, second revision (HCL-32-R2) for the detection of bipolarity in major depressive disorder (MDD) inpatients suffering a current major depressive episode (MDE). METHOD The "Bipolar Disorders: Improving Diagnosis, Guidance, and Education" Arabic module of the HCL-32-R2 was administered to mother-tongue Arabic MDE inpatients between March 2013 and October 2014. Diagnostic and Statistical Manual Fourth edition (DSM-IV) diagnoses were made adopting the mini-international neuropsychiatric interview, using bipolar disorder (BD) patients as controls. RESULTS In our sample (n=500, of whom, BD-I=329; BD-II=70; MDD=101), using a cut-off of 17 allowed the HCL-32-R2 to discriminate DSM-IV-defined MDD patients between "true unipolar" (HCL-32-R2(-)) and "sub-threshold bipolar depression" (HCL-32-R2(+)) with sensitivity=82% and specificity=77%. Area under the curve was .883; positive and negative predictive values were 93.44% and 73.23% respectively. Owing to clinical interpretability considerations and consistency with previous adaptations of the HCL-32, a two-factor solution (F1="hyperactive/elated" vs. F2="irritable/distractible/impulsive") was preferred using exploratory and confirmatory factors analyses. Item n.33 ("I gamble more") and n.34 ("I eat more") introduced in the R2 version of the HCL-32 loaded onto F1, though very slightly. Cronbach's alphas were F1=.86 and F2=.60. LIMITATIONS No cross-validation with any additional validated screening tool. Inpatients only sample; recall bias; no systematic evaluation of eventual medical/psychiatric comorbidities, current/lifetime pharmacological history, or record of severity of current MDE. CONCLUSIONS In our sample, the HCL-32 fairly discriminated between MDD and BD-I but not BD-II, therefore soliciting for replication studies for use in Arabic-speaking depressed inpatients.

Abstract
BACKGROUND Severe deficiency of ADAMTS13 activity leads to von Willebrand factor (VWF) ultralarge multimers with high affinity for platelets, causing thrombotic thrombocytopenic purpura. Other pathological conditions with moderate ADAMTS13 activity exhibit a thrombotic risk. We examined the ADAMTS13 activity in systemic lupus erythematosus (SLE) and its value as a thrombotic biomarker. METHODS ADAMTS13 activity, VWF antigen and multimeric structure, and vascular cell adhesion molecule 1 (VCAM-1) were measured in plasma samples from 50 SLE patients and 50 healthy donors. Disease activity (systemic lupus erythematosus disease activity index; SLEDAI) and organ damage (systemic lupus international collaborating clinics) scores, thrombotic events, antiphospholipid syndrome (APS) and antiphospholipid antibodies (aPLs) were registered. RESULTS SLE patients showed decreased ADAMTS13 activity and high VWF levels compared with controls (66 ± 27% vs. 101 ± 8%, P < 0.01, and 325 ± 151% vs. 81 ± 14%, P < 0.001). VCAM-1 levels were higher in SLE patients (P < 0.05). Considering three groups of SLE patients depending on ADAMTS13 activity (>60%, 60-40% and <40%), comparative analysis showed significant association between ADAMTS13 activity and SLEDAI (P < 0.05), presence of aPLs (P < 0.001), APS (P < 0.01) and thrombotic events (P < 0.01). Reduced ADAMTS13 activity together with increased VWF levels were especially notable in patients with active disease and with aPLs. CONCLUSION ADAMTS13 activity, in combination with other laboratory parameters, could constitute a potential prognostic biomarker of thrombotic risk in SLE.

Abstract
BACKGROUND Socially assistive robotics for elderly care is a growing field. However, although robotics has the potential to support elderly in daily tasks by offering specific services, the development of usable interfaces is still a challenge. Since several factors such as age or disease-related changes in perceptual or cognitive abilities and familiarity with computer technologies influence technology use they must be considered when designing interfaces for these users. OBJECTIVE This paper presents findings from usability testing of two different services provided by a social assistive robot intended for elderly with cognitive impairment: a grocery shopping list and an agenda application. The main goal of this study is to identify the usability problems of the robot interface for target end-users as well as to isolate the human factors that affect the use of the technology by elderly. METHODS Socio-demographic characteristics and computer experience were examined as factors that could have an influence on task performance. A group of 11 elderly persons with Mild Cognitive Impairment and a group of 11 cognitively healthy elderly individuals took part in this study. Performance measures (task completion time and number of errors) were collected. RESULTS Cognitive profile, age and computer experience were found to impact task performance. Participants with cognitive impairment achieved the tasks committing more errors than cognitively healthy elderly. Instead younger participants and those with previous computer experience were faster at completing the tasks confirming previous findings in the literature. CONCLUSIONS The overall results suggested that interfaces and contents of the services assessed were usable by older adults with cognitive impairment. However, some usability problems were identified and should be addressed to better meet the needs and capacities of target end-users.

Abstract
The age of the population in all societies around the world is increasing. Elderly people prefer to maintain their independence, their autonomy and live at home as long as possible. We propose as a solution to this issue a Home Companion Software baptized HoCoS. This solution aims to help the elderly with daily life by providing an ergonomic and familiar interface. The second purpose is to integrate transparent remote healthcare monitoring service that ensures elderly security without disturbing the ergonomics of the application. We present service oriented architecture that offers extensibility and interoperability between heterogonous systems in order to combine several technologies and operators. We carried out ergonomic tests on this solution to evaluate its comfort and ease of use.

Abstract
Recently, 6% of 1,176 Sprague Dawley rats examined in our reproductive toxicity studies presented with dark-red uterine contents with or without fetuses demonstrating delayed development. Sometimes, a high proportion of the litter was found dead, and dystocia with death or preterminal euthanasia of the dam occurred. Microscopic findings in the uterus consisted of necrohemorrhagic and suppurative periplacentitis associated with the presence of bacterial colonies identified as Escherichia coli. In the vagina, similar findings were observed that were associated with mucus accumulation and the presence of a transverse occlusive or partially occlusive thin membrane identified as a vaginal septum. Microscopically, this septum consisted of a thin band of connective tissue covered on both sides by a mucous epithelium that was continuous with vaginal epithelium. In some cases, there was only mucus accumulation retained by a septum in the vagina without evidence of bacterial infection. Serological and histological examinations did not reveal any specific pathogenic agent. The presence of these septa in the vagina most likely favored mucus accumulation, nonspecific ascending bacterial infection, and dystocia. This colony of rats presented with an unusually high incidence of vaginal septa as it was described in different strains of mice and rats in the past. We hypothesized that the use of an impedance meter by the breeder—to determine the phase of the estrous cycle by introducing a probe in the vagina—likely facilitated gestation by perforating the vaginal septum in some cases.

Abstract
Endometriosis is a benign gynecological pathology in which immune system deregulation may play a role in its initiation and progression. In endometriotic lesions, intercellular adhesion molecule-1 (ICAM1) is released from the cell membrane by proteolytic cleavage of its extracellular domain, a process that coincides with increased expression and proteolytic activity of metalloproteinases such as MMP1 and MMP9. The objective of our study was to investigate the association between MMP1 and MMP9 activities and ICAM1 cleavage mediated by tumor necrosis factor (TNF) in eutopic endometrial stromal cells from women with and without (control) endometriosis during culture. The RNA was evaluated by RT-PCR, and the protein was determined by western blot (ICAM1, MMP1), casein or gelatin zymographies (secreted active MMP1 or MMP9 respectively), ELISA (soluble ICAM1 (sICAM1)), and fluorescence assay (secreted active MMP1). Under basal conditions, proMMP9 dimer and MMP9 were higher in endometriosis cell cultures. In stromal cultures derived from control women and those with endometriosis, TNF augmented the intracellular proMMP1 (1.2-fold in control stromal cells) and ICAM1 (1.4- and 1.9-fold), greatly increased MMP1 and proMMP9 levels, and the sICAM1 concentration (2.3- and 4.3-fold) in their media compared with basal levels. The combination of TNF and MMP9 increased the sICAM1 concentration 14-fold in the endometriosis cell media, whereas GM6001 inhibited the stimulatory effect of TNF in both cell cultures. The deregulation of MMP9, and the TNF participation in the MMP1 and proMMP9 secretions, in the MMP9 expression and in the expression and cleavage of ICAM1 may contribute to the pathophysiology of this disease.

Abstract
Although it is suspected that some patients with acute coronary syndromes (ACS) could have a sub-optimal response to aspirin (SASAR), currently a fixed dose of ASA is long-term used in all individuals. This study was designed to determine SASAR and whether a SASAR is a predictor for recurrence of ischemic events in patients on low-dose ASA with a previous ACS. One hundred patients taking ASA 100 mg/day were assessed at 1 and 6 months after a first ACS. SASAR was initially defined as a failure of the ASA treatment to significantly prolong the closure time in the Platelet Function Analyzer (PFA-100). SASAR in these samples was reconfirmed by conventional aggregometry. TXB2 levels were determined in plasma. At one month 49 patients showed SASAR in the PFA-100; only 25 of them showed SASAR by conventional aggregometry. At six months, 39 of 81 patients showed SASAR by PFA-100, but conventional aggregometry detected SASAR in only 12 of the 39 patients. TXB2 levels were significantly higher in patients with SASAR. Five patients with SASAR, by both tests, died during follow-up (p = 0.013). The PFA-100 detected a high rate of SASAR in patients with ACS. This instrument could be used to screen for suboptimal response to the antiplatelet action of ASA. Whether persistence of SASAR could relate to a higher risk of recurrence and how adjusting the dose of ASA could reduce the rate of SASAR are issues that deserve further investigations.

Abstract
The skirt of an artificial cornea must integrate the implant to the host sclera, a major failure of present devices. Thus, it is highly desirable to encourage the metabolic activity of the cornea by using more bioactive, flexible skirt materials. Here we describe attempts to increase the bioactivity of polyether ether ketone (PEEK), high-density polyethylene (HDPE) and ultra-high molecular weight polyethylene (UHMWPE) films. The effectiveness of different strength NaOH pre-treatments to initiate apatite deposition on PEEK, HDPE and UHMWPE is investigated. We find that exposure of PEEK, HDPE and UHMWPE films to NaOH solutions induces the formation of potential nuclei for apatite (calcium phosphate), from which the growth of an apatite coating is stimulated when subsequently immersing the polymer films in 1.5 strength Simulated Body Fluid (SBF). As immersion time in SBF increases, further nucleation and growth produces a thicker and more compact apatite coating that can be expected to be highly bioactive. Interestingly, the apatite growth is found to also be dependent on both the concentration of NaOH solution and the structure of the polymer surface.

Abstract
The identification of human artifacts at the early archaeological site of Monte Verde in southern Chile has raised questions of when and how people reached the tip of South America without leaving much other evidence in the New World. Remains of nine species of marine algae were recovered from hearths and other features at Monte Verde II, an upper occupational layer, and were directly dated between 14,220 and 13,980 calendar years before the present ( approximately 12,310 and 12,290 carbon-14 years ago). These findings support the archaeological interpretation of the site and indicate that the site's inhabitants used seaweed from distant beaches and estuarine environments for food and medicine. These data are consistent with the ideas that an early settlement of South America was along the Pacific coast and that seaweeds were important to the diet and health of early humans in the Americas.

Abstract
BACKGROUND While procoagulant activities of Tissue Factor (TF) have been widely investigated, its possible pro-adhesive properties towards platelets have not been studied in detail. MATERIAL AND METHODS We explored the interaction of platelets with human Tissue Factor (hTF) firmly adsorbed on a synthetic surface of polyvinilidene difluoride (PVDF) using different shear rates. For studies at 250 and 600 s(-1), TF firmly adsorbed was exposed to flowing anticoagulated blood in flat perfusion devices. Deposition of platelets and fibrin were evaluated by morphometric, immunocytochemical and ultrastructural methods. Prothrombin fragment 1 + 2 (F1 + 2) levels were also measured. Experiments at 5000 s(-1), were performed on the Platelet Function Analyzer (PFA-100) with experimental cartridges with collagen (COL) or collagen-hTF (COL + TF). Haemostatic effect of recombinant activated FVIIa (rFVIIa) was assessed in the same experimental settings. RESULTS Platelet deposition on hTF reached 19.8 +/- 1.3% and 26.1 +/- 3.4% of the total surface, at 250 and 600 s(-1), respectively. Fibrin formation was significantly higher at 250 s(-1) than at 600 s(-1) (P < 0.05). The addition of rFVIIa did not influence platelet deposition but raised fibrin formation and thrombin generation at both shear rates (P < 0.05). At 5000 s(-1), closure times (CT) in the PFA-100 were significantly shortened in the presence of hTF (154.09 +/- 14.69 s vs. 191.45 +/- 16.09 s COL alone; P < 0.05). Addition of rFVIIa did not cause a further reduction of CT. CONCLUSIONS Our studies demonstrate that hTF is an adhesive substrate for platelets and suggest that the von Willebrand factor could mediate these interactions. At low and intermediate shear rates, rFVIIa enhanced the procoagulant action of hTF, but this effect was not observed at very high shear rates.

Abstract
13109 The receptors for vascular endothelial growth factor and platelet-derived growth factor (VEGFR-2 and PDGFR) play essential and complementary roles in angiogenesis, and combined inhibition of these receptors may therefore result in potent antitumor activity in vivo. Here we characterized the effects of a small molecule tyrosine kinase inhibitor AG-013736 (Pfizer) in HUVEC and human bladder cancer cells. Previously, AG-013736 was reported to inhibit VEGFRs with picomolar potency and PDGFRs with nanomolar activity. All of the cell lines examined displayed cell surface VEGFR-2 and PDGFR α and β expression as measured by flow cytometry. Low nanomolar concentrations of AG-013736 blocked the HUVEC cell proliferation with inhibition of VEGF receptor 2 and PDGF receptor phosphorylation. AG-013736 caused regression of established subcutaneous human bladder cancer xenografts, effects that were associated with inhibition of VEGFR-2 and PDGFR β phosphorylation but not EGFR phosphorylation and reduction in tumor microvessel densities (MVDs). Our results demonstrate that AG-013736 has substantial anti-angiogenesis activity in preclinical models of human bladder cancer, which warrants further exploration either alone or with the combination of other pre-clinical drugs in bladder cancer treatment. No significant financial relationships to disclose.

Abstract
14055 Background: COX-2 is overexpressed during cancer progression in several solid tumors, including P and BT, and constitutes an attractive therapeutic target. Selective COX-2 inhibitors, such as celecoxib, have been successfully combined with fluoropyrimidine-based regimens, resulting in a lower-than-expected hematologic, GI, and skin toxicity rate. Methods: Advanced P or BT patients (pts), progressing after first-line treatment, were eligible for the study. Capecitabine was administered at 1000 mg/m2 b.i.d. on days 1–14 q3 weeks; celecoxib was administered at 200 mg b.i.d. continuously starting on day 1. PFS was the primary endpoint. ORR, toxicity, OS, clinical benefit (CB), and QoL were secondary endpoints. Assuming that a rate of PFS >15% at 3 mos would be considered of interest in this pt population, an accrual of 28 pts was planned according to the exact single-stage phase II design described by A’Herne. Results: To date, 25 pts have been accrued (M/F: 11/14; median age: 64 yrs, range 39–75; P/BT: 18/7; PS 0–1/2–3: 19/6). All pts completed at least 1 treatment cycle (median: 3, range 1–9). Twenty-three pts are currently evaluable for response: 1 PR and 1 MR (duration: 33 and 27+ wks) were observed, both in pts with P; 5 additional pts showed SD (duration: 10+, 21, 22+, 27, and 42 wks); the remaining 16 pts had PD. All pts and 83 cycles are evaluable for toxicity. Hematological toxicity was negligible; only 4 pts experienced G3 non-hematological toxicities: diarrhea (2 pts, 2 cycles), skin toxicity (1 pt, resolved with treatment delay), asthenia (1 pt, 2 cycles), and GI bleeding (1 pt, requiring treatment interruption after cycle 1). To date, 19 pts have progressed and 15 pts have died: median PFS is 11 wks (range 3–42) and median OS is 16 wks (range 4–54). Nineteen pts had elevated CA19.9 serum levels at baseline, which decreased of > 25% during treatment in 7 pts, remained stable in 3 pts, and increased in 9 pts. The evaluation of CB and QoL is ongoing. Conclusions: CapCel is a feasible and well-tolerated, fully oral, treatment regimen for advanced P and BT patients, which shows activity, albeit modest, even in a second-line setting. Further evaluation of this therapeutic strategy is warranted. No significant financial relationships to disclose.

Abstract
10582 Background: Brain metastases during trastuzumab therapy have been frequently observed. Only a few studies have compared the risk of brain metastases in patients (pts) treated with or without trastuzumab. Methods: In our hospital, between Jun 2000 and September 2005, we conducted a retrospective study in 72 metastatic breast cancer pts treated with first-line mono-chemotherapy (CT) with paclitaxel or docetaxel or vinorelbine ± Trastuzumab (T). Results: Thirty-five pts with HER2 pos disease were treated with T associated with 1st line CT, while 37 pts (16 with HER2 positive tumor, 21 HER2 negative) were not treated with T (NT). Ten HER2 pos NT pts subsequently received T. The median follow-up was 21 months (range1–129); the median age was 54 (range 32–82); the median treatment duration was 5 months (range 1–29). The incidence of recurrence (R), progressive disease in brain (BR), progression free survival (PFS) after first line CT, and overall survival (OS) were reported below: (see Table) Conclusions: This study showed that, after first line chemotherapy, the use of T did not affect the incidence of BR in HER2 pos metastatic breast cancer pts. On the other hand, Her-2 neg seems to predict ‘per se‘ a lower incidence of cerebral spread of disease. [Table: see text] No significant financial relationships to disclose.

Abstract
4126 Background: Molecular targeting of pathways that are deregulated in pancreatic cancer is a promising approach aimed at improving the dismal prognosis of APC pts. However, the clinical impact of novel “biological” drugs (ND) remains to be defined. Methods: All prospective phase III trials comparing single-agent Gemcitabine (G) with either a ND or a combination of ND and G (ND+G) were considered eligible. A pooled analysis was performed and event-based relative risk ratios (RR) with 95% CI were derived through both a fixed- and a random-effect model approach, exploring OS as the primary outcome and PFS and ORR as secondary outcomes. Heterogeneity between different trials was also taken into account. Results: Six trials involving 2361 pts were identified; ND tested included: FTI inhibitors (1 trial), MMP inhibitors (3 trials), EGFR inhibitors (1 trial), and anti-gastrin vaccine (1 trial). The analysis was conducted considering three different subgroups: 1) overall population (2361 patients, 6 trials), 2) ND+G vs G (1879 patients, 4 trials), and 3) ND vs G (482 patients, 2 trials). As shown in the table, no significant differences in either the primary outcome (OS) or the secondary outcome of PFS were observed in the overall population as well as in ND+G vs G trials, while a significant negative trend for ND was found in ND vs G trials with regard to both endpoints. Conversely the evaluation of the secondary endpoint of ORR significantly favored G in the overall population as well as in ND vs G trials, while a not significant negative trend for ND was observed in ND+G vs G trials. Conclusions: G remains the treatment of choice in APC pts. The ND tested, either alone or combined with G, do not seem to add any benefit over G. A better understanding of pancreatic cancer biology and further clinical evaluation of new agents and is needed to improve prognosis in APC pts.

Abstract
4118 Background: Since the introduction of gemcitabine (G), attempts have been made to develop G-based combination regimens to improve the dismal outcome of APC pts. Results of randomized trials, however, have been conflicting and single-agent G presently remains the standard of care for such pts. Methods: All prospective phase III trials comparing single-agent G with G-based polychemotherapy regimens (poly-G) were considered eligible. A pooled analysis was performed and event-based relative risk ratios (RR) with 95% CI were derived through both a fixed- and a random-effect model approach, exploring OS as the primary outcome and PFS and ORR as secondary outcomes. Heterogeneity between different trials was also taken into account. Results: Twelve trials involving 3682 pts were identified. The analysis was conducted considering three different subgroups: 1) overall population (3682 patients, 12 trials), 2) platinum-containing poly-G (PG) vs G (768 pts, 5 trials), and 3) fluoropyrimidine-containing poly-G (FG) vs G (1640 pts, 4 trials). As shown in the table, no significant differences in the primary outcome (OS) were observed in any of the three groups analyzed. Conversely, a significant advantage for poly-G was evident with regard to both PFS and ORR in the overall population as well as in the PG vs G subgroup, although with some heterogeneity. A heterogeneous non-significant trend towards a better PFS and ORR outcome was also observed in the FG vs G subgroup. Conclusions: Single-agent G remains the treatment of choice in APC pts. However, the addition of platinum compounds to G appears to significantly improve PFS and ORR, possibly justifying the use of platinum-based poly-G in younger and fit patients.

Abstract
We report comprehensive atomic force microscopy (AFM) measurements at room temperature of the nanoscale topography and lateral friction on the surface of thin solid films of an intermediate-length normal alkane, dotriacontane (n-C32H66), adsorbed onto a SiO2 surface. Our topographic and frictional images, recorded simultaneously in the contact mode, reveal a multilayer structure in which one to two layers of molecules adsorb adjacent to the SiO2 surface oriented with their long axis parallel to the interface followed by partial layers of molecules oriented perpendicular to the surface. The thicknesses of the parallel and perpendicular layers that we measured with the AFM agree with those inferred from previous x-ray specular reflectivity measurements on similarly prepared samples. We also observe bulk dotriacontane particles and, in contrast with our previous measurements, are able to determine their location. Above a minimum size, the bulk particles are separated from islands of perpendicularly oriented molecules by regions of exposed parallel layers that most likely extend underneath the particles. We find that the lateral friction is sensitive to the molecular orientation in the underlying crystalline film and can be used effectively with topographic measurements to resolve uncertainties in the film structure. We measure the same lateral friction on top of the bulk particles as on the perpendicular layers, a value that is about 2.5 times smaller than on a parallel layer. Scans on top of parallel layers indicate a constant height but reveal domains having different sublevels of friction. We explain this by the domains having different azimuthal orientations of the molecules.

Abstract
BACKGROUND The ability of nitrous compounds to donate nitric oxide (NO), an agent with vasodilating and inhibitory effects on platelet function, has been considered a useful pharmacologic strategy for cardiovascular complications. The purpose of this study was to investigate the effects of a new NO donor, LA419, on platelet interaction in an ex vivo model with human blood circulating through collagen-rich surfaces. MATERIALS AND METHODS Platelet adhesive and cohesive function were analyzed by morphometric procedures after perfusion techniques. Treated blood was exposed to thrombogenic surfaces and platelet interactions were morphometrically evaluated. RESULTS All the concentrations studied of LA419 (10 microM, 20 microM and 100 microM) reduced overall platelet interaction with a collagen surface (27.19 +/- 4.72; 25.52 +/- 3.52; and 23.44 +/- 3.01, P < 0.05, respectively, vs. 32.31 +/- 1.61% in the control). The antithrombotic effect was confirmed by results in cross-sectional studies performed in arterial vessels exposed to circulating blood. Values of thrombus and covered surface at 20 microM LA419 were, respectively, 13.67 +/- 4.97% and 19.01 +/- 5.89%; respect to controls 34.80 +/- 5.29% and 37.93 +/- 5.34% (P < 0.05). Moreover, LA419 reduced significantly thrombus area (88.45 +/- 21.97 microm(2); P < 0.05) with respect to controls (168.45 +/- 21.97 microm(2)) and thrombus height, from an average of 10.27 +/- 1.05 microm in nontreated blood to 7.16 +/- 0.6 microm in treated samples (P < 0.05). CONCLUSION From the present data we can conclude that LA419 possesses a strong antiplatelet action, as demonstrated by its ability to significantly inhibit the interaction of platelet with highly thrombogenic collagen surfaces.

Abstract
We have applied an in vitro perfusion model to explore the potential thrombogenicity of polyester annulolasty fabric used in valve repair and to investigate the possible thromboresistance characteristics conferred by a special heparin coating (Duraflotrade mark treatment). Samples of human blood from i) untreated or ii) heparin-coated extracorporeal circuits were recirculated through annular perfusion chambers containing a) untreated or b) treated annuloplasty cloth material. Perfusion experiments were performed at a shear rate of 600 s(-1) for 20 min. Platelet interaction with the material was morphometrically evaluated. In experiments performed with blood from untreated circuits and cloth material, the average cross-sectional area of platelet mass was 615 +/- 135 microm2. Treatment of cloth material with Duraflotrade mark statistically decreased the area of interacting platelets to 319 +/- 101 microm2 (*p < 0.05, n = 10). Blood samples from heparin-coated extracorporeal circuits showed a decrease of total area of platelets (308 +/- 58 microm2 vs 138 +/- 30 microm2, *p < 0.05, n = 9). The combined treatment of Duraflotrade mark in extracorporeal circuits and cloth material caused a more consistent reduction (p < 0.05). The in vitro perfusion experimental model was sensitive to evaluate the thrombogenic potential of Duraflotrade mark treatment. Our results indicate that the heparin coating of cloth material and extracorporeal circuits improves the biocompatibility of the original material and reduces the thrombogenic profile.

Abstract
BACKGROUND Integrins such as VLA-4 (Very late antigen 4, integrin alpha4beta1) play key roles in cell-cell interactions that are critical for development. Homozygous null knockouts of the VLA-4 alpha4-subunit or VCAM-1 (VLA-4 cell surface ligand) in mice result in failure of the allantois and chorion to fuse leading to interrupted placentation and cardiac development and embryo lethality. Embryo-fetal studies of three VLA-4 antagonists, IVL745, IVL984, and HMR1031 [Crofts et al., Birth Defects Res B 71:55-68 (this issue), 2004] with exposure on gestation days (GD) 6-17 (rat), 6-18 (rabbit) or 6-15 (mouse) showed that only IVL984 treatment resulted in embryo lethality and cardiac defects. Objectives of the current study were to determine the critical period for inducing IVL984-related embryo-fetal effects, and to test the hypothesis that these effects were due to higher embryo drug concentrations. METHODS IVL984 was administered at 40 mg/kg/day to pregnant rats on GD 4 and 5, GD 6 and 7, GD 8 and 9, GD 10 and 11, or GD 12 and 13. Animals were euthanized on GD 21 and uteri and fetuses were examined. A treatment period of GD 10-12 was selected for subsequent toxicokinetic (TK) studies in which IVL984, HMR1031, or IVL745 was administered to pregnant rats and rabbits. On GD 12, maternal plasma, extra-embryonic tissue (placenta and amniotic fluid), and embryonic tissue were collected and analyzed for drug concentrations. RESULTS In the IVL984 critical period study in pregnant rats, treatment on GD 10 and 11 resulted in increased post-implantation loss, skeletal variations, and spiral septal defects similar to those observed in standard embryo-fetal development studies with treatment throughout organogenesis. There were no embryo-fetal effects after treatment on GD 4 and 5, GD 6 and 7, or GD 8 and 9. There was a single aorta malformation after treatment on GD 12 and 13. In the TK studies, IVL745, HMR1031, and IVL984 were all detectable in embryonic tissue and there was no evidence for accumulation. Rat and rabbit embryo exposures (AUC or dose-adjusted AUC) on GD 12 could not explain the observed teratology (IVL984<HMR1031<IVL745). Further analyses incorporating pharmacological activity, clearance, and protein binding data provided a positive correlation between embryonic exposure and teratogenic potency. CONCLUSIONS The critical period for IVL984 in the rat, GD 10 to 11, corresponds to the expression of alpha-4 integrin on the chorion and VCAM-1 on the allantois and myocardium as well as chorioallantoic fusion and formation of the spiral septum. Embryo drug levels adjusted for pharmacological activity, clearance, and protein binding provide a possible explanation for the differing teratogenic potency of IVL984, HMR1031, and IVL745.

Abstract
BACKGROUND Cyclooxygenase (COX)-2-selective non-steroidal anti-inflammatory drugs have been used for anti-inflammatory therapy. However, it has also been described that they may increase risk of cardiovascular events. OBJECTIVES To study the effects of COX2 inhibitor rofecoxib on platelet function using in vitro tests. Results were compared with those obtained in a parallel experiment with acetyl salicylic acid (ASA). METHODS Studies of platelet aggregation, using different agonists, were performed by a turbidimetric method. Adhesive and cohesive function of platelets were analyzed by perfusion techniques, treated blood was exposed to thrombogenic surfaces and platelet interaction was morphometrically evaluated. RESULTS Twenty-five micro M of rofecoxib induced a prolonged lag time and a reduction in the percentage of aggregation when arachidonic acid, ADP or collagen were used as agonists. In perfusion studies with parallel chamber rofecoxib 50 microM and ASA 500 microM reduced overall platelet interaction with the collagen surface (17.4 +/- 3.7, P < 0.05; vs. 32.1 +/- 2.6%P < 0.05 and 17.9 +/- 2.4, vs. 31.9 +/- 3.24, P < 0.05, respectively). In studies performed on annular chambers, 25 micro M of rofecoxib reduced platelet interaction; values of the thrombus and covered surface were 17.4 +/- 4.5%; P < 0.05 and 21.1 +/- 4.1%; P < 0.05, respectively, vs. 30.4 +/- 7.5% and 33.5 +/- 6.5 in the control. ASA did also impair thrombus formation but differences did not reach the levels of statistical significance. Moreover, rofecoxib but not ASA reduced significantly thrombus height and thrombus area (7.4 +/- 0.5 microM; P < 0.005 and 96.0 +/- 21.2 microM(2); P < 0.05 vs. control 11.2 +/- 0.9 microM and 220.0 +/- 47.7 microM(2), respectively). CONCLUSION We conclude that under our experimental conditions, rofecoxib diminished platelet aggregation induced by different agonists and inhibited platelet-mediated thrombogenesis in an in vitro model of thrombosis.

Abstract
BACKGROUND VLA-4 (Very late antigen 4, integrin alpha4beta1) plays an important role in cell-cell interactions that are critical for development. Homozygous null knockouts of the alpha4 subunit of VLA-4 or VCAM-1 (cell surface ligand to VLA-4) in mice result in abnormal placental and cardiac development and embryo lethality. Objectives of the current study were to assess and compare the teratogenic potential of three VLA-4 antagonists. METHODS IVL745, HMR1031, and IVL984 were each evaluated by the subcutaneous route in standard embryo-fetal developmental toxicity studies in rats and rabbits. IVL984 was also evaluated in mice. Fetuses were examined externally, viscerally, and skeletally. RESULTS IVL745 did not cause significant maternal or fetal effects at doses up to 100 or 250 mg/kg/day in rats or rabbits, respectively. HMR1031 treatment resulted in marked maternal toxicity and slight fetal toxicity at the highest tested doses of 200 and 75 mg/kg/day in rats and rabbits, respectively. HMR1031 embryo-fetal effects consisted of slightly lower body weight and crown-rump length in rats and minor sternebral defects in rabbits. IVL984 treatment resulted in minimal maternal effects at doses up to 40, 15, and 100 mg/kg/day in rats, rabbits, and mice, respectively (excluding abortions in rabbits). However, marked developmental effects were observed at the lowest tested IVL984 doses, 1, 0.2, and 3 mg/kg/day in rats, rabbits, and mice, respectively. IVL984 embryo-fetal effects consisted of increased total post-implantation loss due to early resorptions and high incidences of cardiac malformations and skeletal malformations and/or variations. Notably, spiral septal defects were observed in up to 76% of rat fetuses and up to 58% of rabbit fetuses. CONCLUSIONS Dramatic differences in teratogenic potential were observed: IVL745 was not teratogenic, HMR1031 caused slight embryo-fetal effects at maternally-toxic doses, and IVL984 was a potent teratogen at doses where direct maternal toxicity was limited to abortions in rabbits. Prominent effects of IVL984 included embryo lethality and cardiac malformations including spiral septal defects in three species.

Abstract
BACKGROUND AND OBJECTIVES We explored the effect on haemostasis of different factor IX (FIX) concentrates under thrombocytopenic conditions using an in vitro perfusion technique. MATERIALS AND METHODS A moderate experimental thrombocytopenia (25 000-30 000 platelets/microl) was induced by means of a filtration procedure in blood anticoagulated with low-molecular-weight heparin. The effects of three different FIX concentrates - a prothrombin complex concentrate (PCC), an intermediate-purity concentrate (FIX/X), and a high-purity concentrate (HPFIX) - on platelet deposition and fibrin formation on subendothelium were assessed at two different shear rates (600/second and 1200/second). Activation of the coagulation system was monitored through assessment of prothrombin activation fragment 1 + 2 (F1 + 2). RESULTS Fibrin deposition increased after addition of FIX concentrates, but only showed a significant increase in experiments performed after incubation of PCC at the lower shear rate (600/second) (64.25 +/- 9.61% vs. control 31.22 +/- 8.02%; P < 0.05). Addition of FIX concentrates caused a small increase in the percentage of platelet deposition and area of those aggregates. These differences reached levels of statistical significance in the presence of FIX/X and HPFIX in experiments performed at a shear rate of 600/second. F1 + 2 baseline values in anticoagulated thrombocytopenic blood were 1.15 +/- 0.13 nm and reached levels of 2.49 +/- 0.24 and 3.60 +/- 0.33 nm at shear rates of 600 and 1200/second, respectively. Increments in F1 + 2 observed after addition of different FIX concentrates always remained in the previous ranges. CONCLUSIONS Data from the present study provide experimental support favouring the concept that FIX concentrates containing other activated factors could improve haemostasis under conditions of moderate thrombocytopenia.

Abstract
The authors present 2 cases of Merkel cell carcinoma in the head and neck district, evaluating the characteristics and evolution. Merkel cell carcinoma is a rare, highly aggressive neuroendocrine cutaneous neoplasm which is often located in the head and neck district. This carcinoma has the same characteristics as small cell tumors and tends to significant metastatization both through the lymph nodes and through the blood. It is also prone to frequent recurrence. Today diagnosis is facilitated by electron microscopy and immunohistochemistry to search for neurofilaments and cytocheratin 20. The treatment of choice is radical surgery ensuring a tumor-free edge of at least 3 cm, associated with supplementary local radiotherapy. Recurrence is quite frequent despite the treatment strategies applied.

Abstract
BACKGROUND The potential hemostatic effect of infusible platelet membranes (IPM; Cyplex, Cypress Bioscience) prepared from outdated human platelets is investigated. STUDY DESIGN AND METHODS Increasing concentrations of IPM were added to blood samples anticoagulated with low-molecular-weight heparin, in which platelets and WBC counts had been experimentally reduced by a filtration procedure. Thrombocytopenic blood with IPM was circulated in a perfusion chamber at various shear rates (300, 600, and 1200/sec(-1)), and platelet and fibrin deposition on the surface of a damaged vessel was measured. Prothrombin fragments 1 and 2 (F1+2) levels were also monitored. RESULTS Under conditions of severe thrombocytopenia (<6000 platelets/microL) IPM did not increase platelet deposition. However, a dose-dependent increase in fibrin deposition was observed with concentrations of IPM ranging from 0.5 to 2 mg per kg in perfusions at 300 and 600 per sec(-1) (p<0.05 vs. thrombocytopenic blood). Experimental studies performed under conditions of moderate thrombocytopenia and higher shear rates (25, 000-30,000 platelets/microL; at 600 and 1200/sec(-1)) showed that IPM concentrations equivalent to 0.5 or 1 mg per kg improved fibrin deposition (33.5 +/- 9.5% and 37.7 +/- 12.8%, respectively, vs. 22.7 +/- 5.2% in controls) and also promoted a moderate increase in platelet deposition, with a concomitant significant increase in the size of platelet aggregates (p<0.05). Exposure of thrombocytopenic blood to a damaged vessel resulted in an increase of F1+2 levels from 0.8 +/- 0.15 to 1.7 +/- 0.22 nM at 300 per sec(-1) and 1.94 +/- 0.46 nM at 600 per sec(-1). Postperfusion levels of F1+2 after the addition of IPM were always similar to levels in untreated controls. CONCLUSION IPM promotes local procoagulant activity at sites of vascular damage under conditions of severe and moderate thrombocytopenia. IPM also appears to facilitate platelet cohesive functions under conditions of moderate thrombocytopenia.

Abstract
BACKGROUND AND OBJECTIVE Patients with end-stage renal disease or advanced cirrhosis develop bleeding disorders characterized by defective interaction of platelets with damaged subendothelium. The anemia associated with both clinical entities has a negative influence on hemostasis. We evaluated alterations of platelet function in patients suffering from end-stage renal disease (n=21) or hepatic cirrhosis (n=20) using standard aggregometric techniques and the recently developed platelet function analyzer (PFA-100 ). The impact of low hematocrit was also analyzed. DESIGN AND METHODS The hemostatic capacity of platelets was tested in the PFA-100 using citrated blood and standard cartridges containing collagen-ADP (COL-ADP) or collagen-epinephrine (COL-Epi). The hemodynamic influence of hematocrit was also evaluated in blood aliquots in which hematocrit was experimentally increased by adding red blood cells from the same patient. RESULTS Aggregation studies demonstrated abnormal responses to several agonists in both group of patients. Closure times obtained by the PFA-100 for control blood samples were 87+/-3 sec for COL-ADP and 113+/-5 sec with COL-EPi cartridges. Closure times in uremic and cirrhotic patients with average hematocrits of 0.26 and 0.27 respectively were significantly prolonged (139+/-12 and 125+/-14 sec, respectively with COL-ADP and 194+/-29 and 151+/-15 sec with COL-Epi cartridges). A 5% increase in the hematocrit caused a reduction in the closure time to 111+/-7 sec (COL-ADP) and 143+/-14 sec (COL-Epi) in the uremic group and to 86+/-4 sec (COL-ADP) and 115+/-16 sec (COL-Epi) in the cirrhotic group. Our studies confirm the platelet dysfunction in uremic and cirrhotic patients. INTERPRETATION AND CONCLUSIONS The PFA-100 device proved to be useful for testing alterations of primary hemostasis in these acquired disorders and was sensitive enough to detect modifications in hemostasis caused by elevations in hematocrit. Conventional aggregometric tests were able to identify the intrinsic platelet abnormality in uremic and cirrhotic conditions, while the PFA-100 seemed more sensitive in detecting the negative influence of the hematocrit reduction.

Abstract
PURPOSE To study the ability of VWF present in a plasma derived high purity factor VIII concentrate (> or = 100 UI FVIII/mg of protein, Fanhdi) to promote deposition and platelet adhesion on the injured vessel wall, as an indicator of the functionality of said VWF. MATERIAL AND METHODS An in vitro perfusion system was employed. Adequate proportions of platelets and red cells were suspended in a human albumin solution. Aliquots of the studied product were added to obtain levels of 0.4 and 0.8 VWF:AG U/mL in the perfusates. As a comparative group, cryoprecipitate was assayed at similar VWF:Ag doses. Perfusions were performed on rabbit de-endothelialized abdominal aorta segments, placed in annular perfusion chambers, at 37 degrees C and at a flux of 140 mL/min (800 s-1) for 10 min. Results were evaluated as surface covered by platelets and as the percentage ratio between thrombus and surface covered by platelets. FVIII activity was determined by one stage clotting assay. VWF:RCo activity was determined by aggregometry and VWF:Ag by ELISA. RESULTS The VWF:Ag/FVIII:C ratio of Fanhdi is 1.57, while VWF:Roc/FVIII:C ratio is 1.15. The values of platelet deposition obtained, expressed as times of increase in the surface covered by platelets, considering the basal value (without VWF added) as 1, were: Cryoprecipitate 0.4 = 1.93; Cryoprecipitate 0.8 = 2.21; Fanhdi 0.4 = 2.99; Fanhdi 0.8 = 3.40. The ratios between thrombus and surface covered are 13.23%, 23.84%, 42.23%, 21.93% and 26.25% respectively. CONCLUSIONS These data show that VWF present in Fanhdi maintains a high degree of functionality, promoting platelet adhesion on subendothelium under flow conditions, after its incorporation into an albumin-platelet-red cell preparation and resulting in a significant increase in platelet adhesion when compared to the VWF-free basal control.
