description: Here we update the global fit of neutrino oscillations in arXiv:1103.0734 and arXiv:1108.1376 including the recent measurements of reactor antineutrino disappearance reported by the Double Chooz, Daya Bay and RENO experiments, together with latest MINOS and T2K appearance and disappearance results, as presented at the Neutrino-2012 conference. We find that the preferred global fit value of $θ_{13}$ is quite large: $\sin^2θ_{13} \simeq 0.025$ for normal and inverted neutrino mass ordering, with $θ_{13} = 0$ now excluded at more than 10$σ$. The impact of the new $θ_{13}$ measurements over the other neutrino oscillation parameters is discussed as well as the role of the new long-baseline neutrino data and the atmospheric neutrino analysis in the determination of a non-maximal atmospheric angle $θ_{23}$.

description: Context The only available data on quality of life (QoL) in different types of reconstruction techniques for pancreatic head resection (PHR) come from randomized studies and these studies compare only two approaches such as pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG). We have no available QoL data on unselected patients as happens in routine clinical practice; in fact, surgeons tend to prefer one technique over the various other possibilities. Objective To evaluate the QoL in a 2-year follow-up study in consecutive subjects who underwent PHR with different reconstruction techniques (PJ layer end-to-side PJ (LEPJ) or duct-to-mucosa PJ (DMPJ)) with or without trans-anastomotic pancreatic duct stenting (TASPJ)] or PG. Patients One-hundred and 97 consecutive patients enrolled in three Italian surgical centres were studied: 164 (83.2%) had malignant and 33 (16.8%) had benign disease. Methods The EORTC QLQ-C30 questionnaire was administered at 5 different times for evaluation: before surgery and 6, 12, 18 and 24 months after discharge. Results PJ was performed in 189 patients (95.9%) (LEPJ in 124 (65.6%), DMPJ in 65 (34.4%)); 18 out of the 65 DMPJ patients (27.7%) had a TASPJ. A PG was carried out in 8 patients (4.1%) only. In the follow-up evaluation, the QoL significantly improved using the various surgical approaches; improvement over time was not significantly different between the PJ and the PG patients as well as between DMPJ and LEPJ, or between those with and without TASPJ. Conclusions In clinical practice surgeons should use a reconstruction technique in which they are experts; this is supported by the fact that the different surgical reconstruction techniques are equally effective in improving the QoL after PHR.

description: We analyze quantum quenches in integrable models and in particular the determination of the initial state in the basis of eigenstates of the post-quench hamiltonian. This leads us to consider the set of transformations of creation and annihilation operators that respect the Zamolodchikov-Faddeev algebra satisfied by integrable models. We establish that the Bogoliubov transformations hold only in the case of quantum quenches in free theories. In the most general case of interacting theories, we identify two classes of transformations. The first class induces a change in the S-matrix of the theory but not of its ground state, whereas the second class results in a "dressing" of the operators. As examples of our approach we consider the transformations associated with a change of the interaction in the Sinh-Gordon and the Lieb-Liniger model.

Year: 2021

description:

This article focuses on the possibility of studying literature, in particular Hispanic-American one, with the support of comics. Studying the adaptations in comics permits to explore new possibilities for Didactics and to introduce adaptations in comics as a resource in academic courses. In fact the comic is a facilitator in linguistic learning and literary acquisition and it is an efficient tool that permits decoding and analysing contemporary realities. Moreover, it is a vehicle of political, social and cultural contents, and it has a mediator function that is useful in the teaching of foreign languages and literatures. It is an accessible, intuitive, familiar and inclusive language – it knows how to understand the skills of the students – that facilitates the language’s communicative function and that motivates the student in the learning process.

description: We generalize Kirchhoff's point vortex model of two-dimensional fluid motion to a rotor model which exhibits an inverse cascade by the formation of rotor clusters. A rotor is composed of two vortices with like-signed circulations glued together by an overdamped spring. The model is motivated by a treatment of the vorticity equation representing the vorticity field as a superposition of vortices with elliptic Gaussian shapes of variable widths, augmented by a suitable forcing mechanism. The rotor model opens up the way to discuss the energy transport in the inverse cascade on the basis of dynamical systems theory.

description: Context Elevated serum concentrations of troponin T (cTnT) were anecdotically found in patients having acute pancreatitis. Objectives To evaluate the serum levels of cTnT in a consecutive series of patients with acute pancreatitis during the first 72 hours of the disease. Methods Thirty-seven consecutive patients with acute pancreatitis were studied within 24 hours after the onset of pain, having normal renal function at the time of the study and without clinical or electrocardiographic signs of acute myocardial infarction. Serum cTnT, amylase, lipase and C-reactive protein (CRP) were assayed on admission and for two consecutive days using commercially available kits. Results No significant modification of overall serum cTnT concentration was found during the 3 days of the study (P=0.768) while amylase and lipase activity significantly decreased (P<0.001) and CRP significantly increased (P<0.001). In addition, no significant differences in serum cTnT concentrations (P=0.270) and serum amylase (P=0.136) and lipase (P=0.916) activity were found between patients with mild and those with severe pancreatitis during the three days of the study, whereas serum CRP was significantly higher in those with severe pancreatitis as compared to those with mild disease during the entire study period (P<0.001). There were also no significant differences in the serum concentrations of cTnT, amylase, lipase and CRP among the various etiologies of the disease. The ROC curves for serum cTnT, amylase, lipase and CRP used in assessing the severity of acute pancreatitis showed that cTnT (AUC±SE: 0.625±0.053; P=0.025) and CRP (AUC±SE: 0.916±0.027; P<0.001) had an area significantly different from 0.5; thus, only these two molecules were selected as predictors of acute pancreatitis severity. The accuracy of CRP was significantly higher than that of cTnT (P<0.001). Conclusions The presence of elevated levels of cTnT in patients with acute pancreatitis without clinical or electrocardiographic signs of acute myocardial infarction should be noted and these findings should be interpreted as possible rhabdomyolysis and not as acute cardiac injury.

We prove that these systems converge towards steady states, and give a general description of such non-equilibrium steady states in terms of quantum field theory data. We compute the large deviation function, also called the full counting statistics, of energy transfer through the contact. These are universal and satisfy fluctuation relations. We provide a simple representation of these quantum fluctuations in terms of classical Poisson processes whose intensities are proportional to Boltzmann weights.

Intercomprehension and Inclusive Teaching in Primary School

Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

A teaching experience aimed at spreading an inclusive-oriented approach to intercomprehension (or IC) in primary schools is described and discussed in this article. In detail, its goal is to monitor listening comprehension and meaning recognition of Italian-speaking students (68 pupils) in two foreign Romance languages, while testing accessible learning materials, adapted for the needs of dyslexic children. In order to accomplish this goal, the story Tommaso e l’anguria by Mauro Scarpa (2019) is presented in Spanish and French, supported by images in kamishibai format, and children are asked to express their metacognitive knowledge about listening in L2. Data analysis is based on two post-listening monitoring activities and is primarily quantitative. Results show that the young learners understood the global meaning of the story; moreover, they recognised the meaning of more than 50% of the words in Spanish, while in French the percentage was lower. Although the young learner with dyslexia successfully completed all pedagogical tasks, results show that some graphic changes in the paper lexical recognition test are required. The analysis thus confirms the inclusive potential of the intercomprehension-based approach based on the development of L2 oral skills in primary school.

Realism Relativized: A Cultural-Historical Approach to What Images Capture
Creators: name: Prinz, Jesse
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

It is sometimes assumed that there can be a unified and universal analysis of pictorial realism, but this seem implausible. Realism has been understood differently at different times in Western art history art, and art-making traditions elsewhere often aspire to forms of realism that contrast with forms operative in the West. Such variations are presented here, with examples from European, African, and East Asian art. Contact between cultural traditions is also considered. Within analytic aesthetics, some definitions of realism are designed to accommodate cultural diversity, but they face challenges. Leading definitions are critically examined. For example, there are theories that focus on entrenchment, visual skills, and informativeness. None of these constructs captures what realist systems share in common, and none provides an ideal framework for explicitly describing how such systems differ. An alternative theory of pictorial realism is presented. On that theory, realist systems each aim to capture aspects of reality, but they focus on different aspects and provide different manners by which those aspects may be captured.

On the Narrative Potential of Depiction
Creators: name: Bantinaki, Katerina
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

The aim of this article is to defend the narrative potential of depiction against different strands of skepticism that proceed from the lack of temporal order in a single static image: such images, it has been argued, cannot represent the temporal components of narratives – i.e. action(s) and/or causal relations between temporally ordered actions or events. Contemporary philosophers of depiction have strongly challenged the strand of skepticism that focuses on the representation of action(s), but the strand which focuses on the representation of causal relations may seem to be intractable. Yet, I will argue, it rests on a rather partial conception of causation that unduly directs attention to the dimension of time rather than to the dimension of space – the uncontested domain of depiction

description: Objectives To evaluate the hepatocyte growth factor (HGF) and E-cadherin (EC) time course in the early phases of acute pancreatitis and to explore the usefulness of these molecules in assessing the severity of the disease. Patients Sixteen consecutive acute pancreatitis patients (7 males, 9 females; mean age 62.8 years, range 30-79 years) admitted to the hospital within 6 hours after the onset of pain; 16 age- and sex-matched healthy subjects were also studied. Eleven patients had mild pancreatitis and 5 had a severe disease. The acute pancreatitis was of biliary origin in 7 patients (43.8%), due to ERCP in 4 (25.0%), due to alcohol abuse in 2 (12.5%) and idiopathic in the remaining 3 (18.8%). Methods HGF and EC were quantified on hospital admission and for the following 2 days by using commercially available kits (Human HGF Immunoassay and Human sE-Cadherin Immunoassay; R&D Systems Inc., Minneapolis,  MN, USA). Data were analyzed by means of the Kruskal-Wallis and Wilcoxon tests. Results Serum HGF concentrations were significantly higher (P=0.044) in acute pancreatitis patients (mean±SD: 1,895±980 pg/mL) than healthy subjects (mean±SD: 1,246±380 pg/mL) on the second day of the disease, while EC serum levels were significantly higher in acute pancreatitis patients on the first (mean±SD: 57.5±20.4 ng/mL; P=0.015) and the second day (57.7±25.2 ng/mL; P=0.015) of the disease than in healthy subjects (mean±SD: 40.5±11.6 ng/mL). HGF and EC serum concentrations were not significantly different between patients with severe disease and those with mild disease (P>0.089). Conclusions HGF and EC reflect an inflammatory response in acute pancreatitis patients; however, serum levels of these two molecules are not related to the severity of acute pancreatitis.

description: Context The IPMNs of the pancreas represent a challenge for the imaging. Objective To prospectively compare the diagnostic accuracy of three-dimensional contrast enhanced ultrasonography (3D-CEUS) vs. magnetic resonance imaging plus RM cholangio­pancreatography (MRI) in the diagnosis of IPMNs. Methods Thirty consecutive IPMN patients (22 F, 8 M, age 67.1±12.2 years, mean±SD; MRI lesion size 13.8±8.3  mm, mean±SD) were studied. The kappa, McNemar and Wilcoxon matched-pairs statistics were applied. Results Three patients (10.0%) had no diagnostic 3D-CEUS for technical problems. 3D-CEUS was judged to improve the two-dimensional ultrasonography (2D-US) findings in evaluating the pancreatic lesions in 14 patients (51.9%). Twelve (44.4%) main duct IPMN cases were identified by 3D-CEUS vs. no cases by MRI (P<0.001). IPMN localization showed a poor agreement between 3D-CEUS and MRI (kappa=0.058), whereas a good agreement was found in detecting the presence of calcifications (kappa=1.000). Significant differences between 3D-CEUS and MRI were found regarding the number of lesions detected (1.4±0.8 vs. 3.8±3.6; P<0.001), the detection of mucinous plugs (3.7% vs. 50.0%; P<0.001), chronic pancreatitis (7.4% vs. 29.6%; P=0.031), pancreatic atrophy (0% vs. 48.1%; P<0.001), high thick septa (22.2% vs. 55.6%; P=0.004) and mural nodules (25.9% vs. 3.3%; P=0.016), while presence of dilation of both the Wirsung duct (40.7% vs. 18.5%; P=0.070) and the secondary duct communicating with the main pancreatic duct (0% vs. 3.3%; P=1.000) were not significant. Conclusions The 3D-CEUS compared to 2D-US improves the IPMN diagnosis. It may be utilized to better evaluate these patients after 2D-US examination. MRI remains the gold standard technique.

A Lanczos Method for Approximating Composite Functions
Creators: name: Constantine, Paul G.
name: Phipps, Eric T.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: We seek to approximate a composite function h(x) = g(f(x)) with a global polynomial. The standard approach chooses points x in the domain of f and computes h(x) at each point, which requires an evaluation of f and an evaluation of g. We present a Lanczos-based procedure that implicitly approximates g with a polynomial of f. By constructing a quadrature rule for the density function of f, we can approximate h(x) using many fewer evaluations of g. The savings is particularly dramatic when g is much more expensive than f or the dimension of x is large. We demonstrate this procedure with two numerical examples: (i) an exponential function composed with a rational function and (ii) a Navier-Stokes model of fluid flow with a scalar input parameter that depends on multiple physical quantities.
A gauge approach to the "pseudogap" phenomenology of the spectral weight in high Tc cuprates

description: We assume the t-t'-J model to describe the CuO_2 planes of hole-doped cuprates and we adapt the spin-charge gauge approach, previously developed for the t-J model, to describe the holes in terms of a spinless fermion carrying the charge (holon) and a neutral boson carrying spin 1/2 (spinon), coupled by a slave-particle gauge field. In this framework we consider the effects of a finite density of incoherent holon pairs in the normal state. Below a crossover temperature, identified as the experimental "upper pseudogap", the scattering of the "quanta" of the phase of the holon-pair field against holons reproduces the phenomenology of Fermi arcs coexisting with gap in the antinodal region. We thus obtain a microscopic derivation of the main features of the hole spectra due to pseudogap. This result is obtained through a holon Green function which follows naturally from the formalism and analytically interpolates between a Fermi liquid-like and a d-wave superconductor behavior as the coherence length of the holon pair order parameter increases. By inserting the gauge coupling with the spinon we construct explicitly the hole Green function and calculate its spectral weight and the corresponding density of states. So we prove that the formation of holon pairs induces a depletion of states on the hole Fermi surface. We compare our results with ARPES and tunneling experimental data. In our approach the hole preserves a finite Fermi surface until the superconducting transition, where it reduces to four nodes. Therefore we propose that the gap seen in the normal phase of cuprates is due to the thermal broadening of the SC-like peaks masking the Fermi-liquid peak. The Fermi arcs then correspond to the region of the Fermi surface where the Fermi-liquid peak is unmasked.

description: Context To prolong chemotherapy over 6 months in metastatic pancreatic adenocarcinoma (MPA) has unproven benefit and is hampered by cumulative toxicity. Objective This phase II trial explored the role of maintenance sunitinib (MS), using an observation (O) group as calibration arm. The predictive role of circulating endothelial cells (CEC) and of functional polymorphisms (SNPs) of genes involved in sunitinib activity, metabolism and transport (VEGFA, VEGFR-2, CYP3A5, CYP1A1, ABCB1, ABCG2) was explored. Methods Patients with pathologic diagnosis of MPA, PS >50%, no PD after 6 months of chemotherapy were randomized to O (arm A) or MS (37.5 mg daily) for 6 months (arm B). Primary endpoint was PFS-6. The target enrolment was 26 patients among whom >5 PFS-6 were necessary to declare MS of interest. CEC and SNPs were evaluated on baseline blood samples. Results Twenty-eight patients were assigned arm A and 28 arm B, one of whom was ineligible (kidney cancer). Baseline characteristics were balanced; previous chemotherapy was (A/B): gemcitabine 2/3; combination chemotherapy 25/25. Median duration of MS was 2.8 months. Grade 3-4 toxicity (arm B) was 15% neutropenia; 12% thrombocytopenia and hand-foot syndrome, 8% diarrhea. PFS-6 was 4% and 22%; median PFS was 2.0 and 3.2 months (P=0.01); 2-year OS was 5% and 22% (P=0.12). CEC analysis (n=46; 84%) showed a longer median PFS in untreated patients with CEC <30 when compared to >30 (2.9 versus 1.9 months; P=0.08); a significantly increased PFS in patients with CEC >30 treated by MS versus O (3.4 months; P=0.02); no PFS difference between arms in patients with CEC <30. Genotyping analysis (n=43; 78%) showed a longer median OS among arm B patients with ABCB1 3435TT genotype as compared to 3435CC/CT genotype (26 versus 7 months; P=0.11); and with VEGFA -634GC-CC genotype as compared to -634GG genotype (11 versus 6 months; P=0.013). Conclusions MS fulfilled the primary endpoint of the trial and yielded remarkable OS figures. CEC and SNPs may be useful to predict benefit from MS.

description:

In the last few years, Content and Language Integrated Learning (CLIL) has been extensively implemented in the Italian school system and particularly in the Autonomous Province of Trento. This article aims to analyse students’ perception of the quality of their CLIL experience since they are the final recipients of CLIL. Results suggest that students acknowledge the positive impact of CLIL on their L2 proficiency (English). However, the success of CLIL seems to be strongly dependent on the CLIL teacher’s linguistic competence in the L2 and on the CLIL curriculum design, which should avoid oversimplification of the subject matter taught by means of the L2.

description: A Janus heterocycle is one kind of heterocycle that possesses hydrogen bonding donors or acceptors at both sides compared to regular nuclear bases. This provides an interesting synthetic target as well as a tool for testing an intriguing biological hypothesis related to DNA recognition, namely can both strands in the DNA duplex be recognized simultaneously by a single oligomeric strand of Janus heterocycles? In order to test this hypothesis, oligonucleotides containing at least one Janus heterocycle must be synthesized. One challenge involved in the synthesis of oligonucleotides with a Janus heterocycle is the extremely low solubility of Janus heterocycle phosphoramidites in organic solvents, namely MeCN. To solve the solubility issue, two sulfone-masked Janus-AT phosphoramidites were designed and constructed in this thesis. In addition to questions of solubility, the other obstacle related with Janus heterocycle oligonucleotide construction is the potential for deglycosylation, analogous to depurination, which might occur under the acidic conditions used during solid phase synthesis of oligonucleotides. The carbocyclic analog of deoxyribose, in lieu of 2-deoxyribose was employed to construct Janus heterocycle phosphoramidites in order to obviate the potential for depurination-like elimination of the nucleobase from the sugar.

description:

This essay aims to analyse errors made by Egyptian students in learning the Italian verbal system. We try to explain the most frequent errors highlighting the causes that generated them. This thesis is based on the analysis of compositions written by 60 Egyptian learners enrolled in the second year of the Italian degree course at the Faculty of Al Alsun. The analysis revealed that the verb is a part of the speech in which almost all students have made errors. The causes of the errors are numerous: the influence of the Arabic language; the difference between the structure of the tense in the Italian language and in the Arabic language and the intrinsic difficulties of the Italian language.

description: We study the diffusion of information in an overlaying social-physical network. Specifically, we consider the following set-up: There is a physical information network where information spreads amongst people through conventional communication media (e.g., face-to-face communication, phone calls), and conjoint to this physical network, there are online social networks where information spreads via web sites such as Facebook, Twitter, FriendFeed, YouTube, etc. We quantify the size and the critical threshold of information epidemics in this conjoint social-physical network by assuming that information diffuses according to the SIR epidemic model. One interesting finding is that even if there is no percolation in the individual networks, percolation (i.e., information epidemics) can take place in the conjoint social-physical network. We also show, both analytically and experimentally, that the fraction of individuals who receive an item of information (started from an arbitrary node) is significantly larger in the conjoint social-physical network case, as compared to the case where the networks are disjoint. These findings reveal that conjoining the physical network with online social networks can have a dramatic impact on the speed and scale of information diffusion.

description: We study the interplay of superfluidity, glassy and magnetic orders of hardcore bosons with random frustrating interactions. In the classical limit, this model reduces to a $\pm J$ Edwards-Anderson Ising model with concentration $p$ of the ferromagnetic bonds, which hosts a glassy-ferromagnetic transition at a critical concentration $p_c^{\rm cl}\sim 0.77$ on a 3D cubic lattice. Our quantum Monte Carlo simulation results using the worm algorithm show that quantum fluctuations stabilize the coexistence of superfluidity and glassy order ("superglass"), and shift the (super)glassy-ferromagnetic transition to $p_c> p_c^{\rm cl}$. In contrast, antiferromagnetic order coexists with superfluidity to form a supersolid, and the transition to the glassy phase occurs at a higher $p$.

The Treachery of Images: Why Images Do not Exist and There Are Only Flat Objects
Creators: name: Manzotti, Riccardo
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

Do images exist? In this paper I argue that the notion of an image is ontologically empty – i.e., images are no more than a cultural invention akin to epicycles in astronomy. There are only flat objects engaged in various causal roles. In this paper I will defend the thesis that in visual culture, in the neurosciences, and in philosophy of mind, there is no convincing evidence in favor of their existence. Moreover, I will outline a series of arguments aiming at showing that images do not exist. I will discuss briefly discuss why many authors – from the iconic turn to the neurosciences – use the notion of image as though it were something real. I will conclude suggesting to drop the subject-object divide and to consider a completely flat ontology made only of (relative) objects.

Energetic and structural impact of cyclic nucleotide binding to hyperpolarization-activated cyclic nucleotide-gated channels
Creators: name: Chow, Sarah Sue Wen
Publisher: name: University of British Columbia
Year: 2014

description: Hyperpolarization-activated Cyclic Nucleotide-gated, HCN, channels contribute to the membrane potential of excitable cells including pacemaker cells of the heart and neurons in the brain. By binding to the inner side of the HCN channel, cAMP facilitates channel opening, but the underlying mechanism has been mainly inferred from relating cAMP concentration to the degree of facilitation. Concentration-response relations reflect the tightly coupled process of cAMP binding and channel opening. The strength of binding and how it is linked to channel opening is not known. Furthermore, cAMP facilitation is not equal among the four mammalian HCN isoforms and the extent to which cAMP binding affinity contributes to these differences is not known.My experiments support the conclusion that cAMP binds to one site of the isolated tetrameric C-terminus of HCN2 and HCN4 with high affinity and to three sites with low affinity revealing negative cooperativity. In contrast, only low affinity binding was observed in HCN1 with energetics of binding that were similar to those of the low affinity binding to HCN2. Cyclic AMP enhanced oligomerization of the HCN2 C-terminus in solution, but had a negligible effect on oligomerization of the HCN1 C-terminus. Oligomerization in solution is thought to reflect the formation of a gating ring in the intact channel that facilitates opening. Together, this suggests that HCN1 functions as though already disinhibited, explaining its easier opening in the absence of cAMP, its smaller facilitation of opening, and lack of negative cooperativity upon cAMP binding. Lysine substitution at residue 488 of HCN2, initially identified in an individual with idiopathic generalized epilepsy, eliminated negative cooperativity and reduced oligomerization of the isolated C-terminus upon cAMP binding. This likely reflects a decrease in its ability to form a gating ring in the intact channel and explains the reported inhibition of opening by this mutation.The work presented in this thesis demonstrates the value of studying the C-terminus of the HCN channel in isolation to uncover the mechanism by which the HCN C-terminus and cAMP binding control channel opening that would otherwise be hidden by functional experiments.
Motoric Understanding and Aesthetic Appreciation

description:

Standard philosophical studies on picture perception usually investigated the peculiar nature of pictorial experience and the way aesthetic appreciation can be generated during this experience. Recently, however, the philosophical literature has also focused on a new aspect of picture perception: the possible involvement that the visual states related to action processing may actually play in pictorial experience. But this role has been studied only in relation to the understanding of the nature of pictorial experience, qua visual experience. This paper offers some preliminar speculation, which may guide future research, on the role of action in aesthetic appreciation of pictures.

description: Context Pancreatic adenocarcinoma (PA) is mostly metastatic at time of diagnosis with a poor survival. Objective We decided to explore whether metastatic site correlates with prognosis. Methods Patients with pathologic diagnosis of metastatic PA, treated at our Institution with upfront combination chemotherapy between April 1997 and August 2010 were eligible for this analysis. Baseline tumor assessment consisted of contrast enhanced computed tomography scan of the abdomen and the thorax. Results Two-hundreds and sixty-five patients with metastatic PA, median age 60 years; median PS 90; median CA 19-9 1,048 were eligible; 19 (7.2%) had prior pancreatic surgery. Metastases were located: in a single organ (n=150; 56.6%); liver (n=227; 85.3%); peritoneum (n=32; 12.1%); lung (n=53; 19.9%). Lung was the only metastatic site in 15 cases (5.6%). Median and 1-year overall survival (OS) was 9.0 months and 32.2%. Prior surgery correlated with better OS (11.7 and 51.0% versus 8.9 and 30.8%; P=0.006); liver metastases with worse OS (median and 1-year OS: 8.8 months and 29.7% versus 11.1 and 47.4%; P=0.005); while no difference in OS was observed based on number of metastatic sites (P=0.37); peritoneal (P=0.50) or lung metastases (P=0.10). Patients with lung as isolated metastatic site lived longer (17.3 months and 66.7%) with respect to the whole population (9.0 months and 30.1%; P=0.01) and to patients with lung metastases associated to other metastatic sites (8.8 months and 34.2%; P=0.07). Conclusions Prior surgery and metastatic site correlate with prognosis and should be used as a stratification criterion in prospective trials. Patients with lung as isolated metastatic site has a particularly good prognosis.

description:

Marks individually or in combination constitute images that represent objects. How do those images represent those objects? Marks vary in style, both between and within images. Images also vary in style. How do those styles relate to each other and to the objects that those images represent? Referencing a diverse range of images, we answer the first question with a response-dependence theory of image representation derived from Mark Johnston, differentiating Lockean primary qualities of marks from secondary qualities of images. We answer the second question with a perceptual theory of style derived from Paul Grice, differentiating physical style from image style, and representing conventionally from representing conversationally.

description: Context Increased BMI is generally considered a risk factor for postoperative complications after pancreaticoduodenectomy (PD). In contrast, data are scarce regarding BMI as long term prognostic factor. Objective To evaluate the impact of BMI on short and long term results after PD. Methods Patients undergone PD 2004-2010 was retrieved from our prospective database. Demographics, peri-operative data, morbidity, mortality, pancreatic fistula (PF) rate, length of stay (LOS), and survival were analyzed. The cohort was divided by BMI into overweight/obese (O; BMI ≥ 25 kg/m2) and controls (C; BMI <25 kg/m2). Results A total of 367 PDs were included (O=141/C=226). No significant differences were found between O and C regarding demographics, peri-operative data, morbidity (O 47% vs. C 54%) or mortality (O 3.4% vs. C 3.5%). O had a significantly higher rate of PF (O 20% vs. C 9.5%; P=0.006) and longer LOS (O 18 days vs. C 15 days; P=0.05) compared to C. An increasing risk for PF was observed with increasing BMI: underweight 0%, normal-weight 10%, overweight 16%, and obese 32% PF rate, respectively. A similar 1-, 3- and 5-year survival rate was observed for O and C both in pancreatic ductal adenocarcinoma, and in other periampullary cancers. Conclusion Overweight/obesity increases the risk for PF and thus LOS, but do not otherwise alter short term outcome or survival rate after oncological PD for pancreatic or periampullary cancer.

description: Context The incidence of incidentally found cystic tumors of the pancreas has increased tremendously during the last years. The diagnosis and management of these lesions remain, in many cases controversial. No data are available regarding the clinical history of these lesions in patients undergoing immunosuppressive treatment. Case report A 65-year-old woman previously liver transplanted due to familial amyloidosis. After transplantation she developed stricture of the bile duct anastomosis that was repeatedly and successful treated by endoscopy. At the pre-transplant CT-scan a suspected multifocal branch duct (BD)-IPMN of the pancreas was observed. The biggest lesion at that time was 15 mm in diameter and located in the pancreatic tail. During follow-up after transplant, a progressive increase in size of this cystic lesion was observed until the last CT in autumn 2011 when the diameter was 35 mm. No sign of degeneration (symptoms, mural nodules) were observed. Following the IAP guidelines for treatment of BD-IPMN the patient was evaluated for surgery. Due to immunosuppressive regimen, and thus related increased risk for major surgery, a surgical enucleation of the lesion for diagnostic and therapeutic purpose was done. The post-operative course was uneventful. The pathological diagnosis was BD-IPMN with low grade dysplasia. Conclusion Transplanted patients are more prone to develop complications after major surgery and at higher risk to develop cancer. Enucleation of suspected pre-malignant lesions of the pancreas may therefore be a useful approach to confirm diagnosis but also to treat this kind of lesions.
