description: Context Carcinosarcomas are neoplasms with mixed carcinomatous and sarcomatous elements, which rarely occur in the pancreas. Case report A 62-year-old man was admitted to our institute for the presence of intense abdominal pain, worsening of a type II diabetes and weight loss (10 kg in 3 months). The tumor markers (CEA, CA 19-9) were within normal range. A CT scan showed a large pancreatic head solid mass of about 5 cm in diameter, with central necrotic area with septa, peripheral contrast-enhancement and compression and dislocation of the superior mesenteric vein for a tract of 2.5 cm (G3). An US-guided percutaneous biopsy diagnosed a malignant, high grade spindle cells neoplasia with immunophenotypic pattern of sarcomas. Surgical approach was planned and a total pancreatectomy with vascular resection was performed. The vascular resection included a 8 cm tract of portal-mesenteric trunk and the reconstruction was performed using a donor’s femoral vein homograft. Pathological examination of the specimen showed a solid mass of 6 cm in diameter, with infiltration of the portal vein. Lymph nodes (n=48) were negative and the surgical margins were tumor-free. Microscopically the tumor was characterized by high grade, polymorphous, intensely desmin-positive spindle cells mixed with areas of moderately differentiated ductal adenocarcinoma. The remaining pancreatic gland was interested by a diffuse lympho-plasmacellular GEL-type acute pancreatitis. A final diagnosis of carcinosarcoma, pT3N0M0, was performed. The postoperative course was uneventful and the patient was discharged in post-operative day 14th. He is dead, 4 months after surgery. Conclusion In literature only 10 cases of pancreatic carcinosarcomas have been described All cases were treated surgically and they showed a poor prognosis (average 6 months) and a rapid recurrence of the disease as in our case.

description: Context Rates of microscopic margin involvement (R1), after pancreaticoduodenectomy for peri-ampullary cancer, vary markedly from 16% to more than 75% .One of the reasons is the lack of international consensus protocol for the pathological examination. Objectives To evaluate the rates of R1 in patients undergoing pancreaticoduodenectomy for peri-ampullary malignancy after the application of a standardized protocol of specimen’s margination. Methods From January 2010 to May 2012 data regarding 71 patients (Group A) undergoing pancreaticoduodenectomy for periampullary cancer, were collected in a prospective database. In all patients the histological examination was carried out according of a standardized protocol of specimen’s margination. R1 was defined as the presence of microscopic involvement <1 mm from the margin. The rate of R1 was compared with a historical cohort of 23 patients (Group B), undergoing pancreaticoduodenectomy for periampullary cancer without a standardized protocol of margination. The statistical analysis was carried out by using the Fischer exact test, the Pearson chi square test, the t-test and the logistic regression. Results The two groups were similar regarding sex, age, type and extension of resection and histological data (T, N, type of tumor). R1 rate was statistically significant higher in Group A than Group B (89.2% vs. 66.7%, P=0.015). The logistic regression, conducted for all patients, showed that presence of ductal adenocarcinoma or cholangiocarcinoma and T status increased significantly the risk of R1 (OR=41.4, P=0.004 and OR=6.3, P=0.050, respectively). The multivariate analysis including the type of margination showed that also the application of a standardized margination protocol was an independent factor related to R1 (OR=4.3; P=0.030). Conclusion Lack of standardization of pathological examination and controversy regarding the definition of microscopic margin involvement have resulted in variation of reported R1 rates Margin involvement in pancreatic cancer is a frequent and prognostically significant finding when specimens are assessed using a standardized protocol of specimen’s margination.

description: We study the evolutionary dynamics of an asexual population of nonmutators and mutators on a class of epistatic fitness landscapes. We consider the situation in which all mutations are deleterious and mutators are produced from nonmutators continually at a constant rate. We find that in an infinitely large population, a minimum nonmutator-to-mutator conversion rate is required to fix the mutators but an arbitrarily small conversion rate results in the fixation of mutators in a finite population. We calculate analytical expressions for the mutator fraction at mutation-selection balance and fixation time for mutators in a finite population when mutational effects are weaker (regime I) and stronger (regime II) than the selective effects. Our main result is that in regime I, the mutator fraction and the fixation time are independent of epistasis but in regime II, mutators are rarer and take longer to fix when the decrease in fitness with the number of deleterious mutations occurs at an accelerating rate (synergistic epistasis) than at a diminishing rate (antagonistic epistasis). Our analytical results are compared with numerics and their implications are discussed.

description: Context In 2010 WHO released a new classification system for pancreatic endocrine tumors (PETs). Objectives To compare WHO-2010 with WHO-2000 classification in patients affected by PETs who underwent surgery. Methods Data regarding 67 patients were extracted from a dedicate database containing 92 patients undergone surgical exploration for pancreatic neuroendocrine tumors (pNETs). Patients without Ki-67 determination were excluded. Sex, age, presence of symptoms, hormonal status, site of tumor, presence of MEN1, surgical procedure, R status, TNM-ENETS stage, WHO 2000 and WHO 2010 classification, Ki-67, disease specific survival (DSS) with univariate and multivariate analyses. Results There were 36 (53.7%) females and 31 (46.3%) males. Mean age of patients was 57±13 years. Symptoms were present in 49 (73.1%) patients. Forty-nine (73.1%) patients had non-functioning pNETs and the tumour was located more frequently in the head (34.3%) and body (37.3%). Seven (10.4%) patients were affected by MEN1. R0 resection was carried out in 54 cases (80.6%) cases. Ki-67 was <2% in 30 (44.8%) patients, ranged 2-20% in 33 (49.3%) patients and was >20% in 4 (6.0%) patients. According WHO-2000, 33 (49.3%) patients had a well differentiated tumours (WDT), 26 (38.8%) had well differentiated carcinoma (WDCa), and 8 (11.9%) had poorly differentiated carcinoma (PDCa). According to WHO 2010, 30 (44.8%) pNETs G1, 33 (49.3%) pNETs G2 and 4 (6.0%) pancreatic neuroendocrine carcinomas (pNECs) G3. According TNM-ENETS stage there were 28 (41.8%), 4 (6.0%), 24 (35.8%) and 11 (16.4%) patients in stage I, II, III, and IV, respectively. Mean DSS was 263±17 months. Multivariate analysis found that WHO 2000 was the only independent factor related to DSS (HR=24; P=0.003). Conclusion WHO 2000 remains in our experience the best factor predicting DSS in patient affected by pNETs.

Characteristics of the posttraumatic stress disorder traumatic stressor : a study of rural and northern first responders
Creators: name: Regambal, Marci Joan
Publisher: name: University of British Columbia
Year: 2014

description: A diagnosis of posttraumatic stress disorder (PTSD) requires meeting Criterion A, which states that the individual must: 1) experience, witness, or be confronted with an event that involved actual or threatened death, serious injury, or threat to one’s physical integrity (Criterion A1); and 2) experience intense fear, helplessness, or horror during or shortly after the event (Criterion A2). Despite various attempts to define Criterion A, a strong etiological link between the event and resulting PTSD has remained elusive. The overarching purpose of the current study was to examine characteristics of traumatic stressors beyond Criterion A. A cross-sectional, repeated-measures design was used to examine Criterion A1 events under two conditions: when an event was associated with lasting distress (i.e., distressing event) and when an event was not associated with lasting distress (i.e., control event). This research addressed four objectives. First, it identified characteristics of Criterion A1 events that evoked extreme amounts of distress (i.e., PTSD symptoms). Second, it examined whether these characteristics were more relevant for distressing events compared to control events. Third, it tested whether event characteristics added incremental value in predicting PTSD symptoms above meeting Criterion A. Finally, it tested hypothesized relationships between event characteristics and processes implicated in cognitive models, namely peritraumatic dissociation and posttrauma cognitions. The present study surveyed 181 first responders from northern British Columbia. First responders repeatedly experience Criterion A1 events, which allowed them to rate the relevance of event characteristics for both types of events. A principal component analysis of diverse event characteristics revealed that distressing events were characterized by chaos and resource limitations, which were both rated as significantly more descriptive of distressing events compared to control events. As hypothesized, both event characteristics predicted PTSD symptoms above meeting Criterion A, which was not associated with PTSD symptoms. Consistent with cognitive models, the event characteristics influenced peritraumatic dissociation and posttrauma cognitions, which in turn predicted PTSD symptoms. Moreover, the affect of the event on PTSD symptoms was partially mediated by these cognitive variables. Overall, the results of this study are novel because they underscore the importance of examining event characteristics beyond Criterion A.

description: We introduce and experimentally demonstrate a technique for performing quantum state tomography on multiple-qubit states despite incomplete knowledge about the unitary operations used to change the measurement basis. Given unitary operations with unknown rotation angles, our method can be used to reconstruct the density matrix of the state up to local sigma-z rotations as well as recover the magnitude of the unknown rotation angle. We demonstrate high-fidelity self-calibrating tomography on polarization-encoded one- and two-photon states. The unknown unitary operations are realized in two ways: using a birefringent polymer sheet---an inexpensive smartphone screen protector---or alternatively a liquid crystal wave plate with a tuneable retardance. We explore how our technique may be adapted for quantum state tomography of systems such as biological molecules where the magnitude and orientation of the transition dipole moment is not known with high accuracy.

description: One of the least understood properties of comets is the compositional structure of their nuclei, which can either be homogeneous or heterogeneous. The nucleus structure can be conveniently studied at millimeter wavelengths, using velocity-resolved spectral time series of the emission lines, obtained simultaneously for multiple molecules as the body rotates. Using this technique, we investigated the sources of CH3OH and HCN in comet 103P/Hartley 2, the target of NASA's EPOXI mission, which had an exceptionally favorable apparition in late 2010. Our monitoring with the IRAM 30 m telescope shows short-term variability of the spectral lines caused by nucleus rotation. The varying production rates generate changes in brightness by a factor of 4 for HCN and by a factor of 2 for CH3OH, and they are remarkably well correlated in time. With the addition of the velocity information from the line profiles, we identify the main sources of outgassing: two jets, oppositely directed in a radial sense, and icy grains, injected into the coma primarily through one of the jets. The mixing ratio of CH3OH and HCN is dramatically different in the two jets, which evidently shows large-scale chemical heterogeneity of the nucleus. We propose a network of identities linking the two jets with morphological features reported elsewhere, and postulate that the chemical heterogeneity may result from thermal evolution. The model-dependent average production rates are 3.5x10**26 molec/s for CH3OH and 1.25x10**25 molec/s for HCN, and their ratio of 28 is rather high but not abnormal. The rotational temperature from CH3OH varied strongly, presumably due to nucleus rotation, with the average value being 47 K.

description: Context Annular pancreas is an uncommon congenital anomaly in which the pancreatic tissue forms a complete (25%) or partial (75%) ring around the descending duodenum. It usually presents in infants with abdominal pain, nausea and vomiting due to obstruction to gastric emptying. It rarely may manifest later in life. Case report A 40-year-old man was referred for further evaluation of a 1-year history of fluctuating pancreatic hyperenzymemia with mild elevations both of amylase and lipase, typically less than twice the normal range. The patient was completely asymptomatic and in good physical condition. He had a past medical history of right kidney dysplasia. He was not on any medication and had no alcohol and smoke habit. Other routine serological tests were within the normal range. Abdominal ultrasound, magnetic resonance imaging and computed tomography (CT) performed prior to admission demonstrated no pancreatic abnormalities. We performed an endoscopic ultrasonography (EUS) with radial echoendoscope (GF-UE160, Olympus, Hamburg, Germany) that showed a band of pancreatic tissue completely surrounding the duodenum. Pancreatic ducts were normal, both in tissue band than throughout the pancreas. Any feature of chronic pancreatitis was seen. Endoscopy showed narrowing of the descending duodenum with a normal mucosal pattern. Because of total absence of symptoms no treatment has been recommended. At 12-month follow up the patient was still asymptomatic with no substantial differences in laboratory tests. Conclusion CT and MR cholangiopancreatography (MRCP) are generally useful for diagnosis of annular pancreas. Endoscopic cholangiopancreatography (ERCP) is able to demonstrate pancreatic duct encircling the duodenum. However, ERCP is technically difficult in cases with duodenal obstruction and it is known that the procedure may potentially induce or aggravate acute pancreatitis. Because of its ability in evaluating not only the pancreatic duct but also the parenchyma, EUS seems to be the best method for the diagnosis of pancreatic disease. EUS appears to have an important role in the diagnosis of annular pancreas even when previously unsuspected. Annular pancreas as a possible finding in case of asymptomatic pancreatic hyperenzymemia should be kept in mind.

description: We combine moduli stabilisation and (chiral) model building in a fully consistent global set-up in Type IIB/F-theory. We consider compactifications on Calabi-Yau orientifolds which admit an explicit description in terms of toric geometry. We build globally consistent compactifications with tadpole and Freed-Witten anomaly cancellation by choosing appropriate brane set-ups and world-volume fluxes which also give rise to SU(5)- or MSSM-like chiral models. We fix all the Kaehler moduli within the Kaehler cone and the regime of validity of the 4D effective field theory. This is achieved in a way compatible with the local presence of chirality. The hidden sector generating the non-perturbative effects is placed on a del Pezzo divisor that does not have any chiral intersections with any other brane. In general, the vanishing D-term condition implies the shrinking of the rigid divisor supporting the visible sector. However, we avoid this problem by generating r

description: Context Chronic inflammation is suggested to play a key role in cancer initiation and progression. Epithelial-mesenchymal transition (EMT) is an essential developmental program that becomes reactivated in adult tissues to promote the progression of cancer. EMT is characterized by an enhanced cell motility, the loss of the epithelial marker E-cadherin (CDH1), and the overexpression of the mesenchimal marker N-cadherin (CDH2). Master regulators of EMT are the transcription factors Snail, Slug, ZEB and Twist. Objective To ascertain whether the inflammatory molecules S100A8, S100A9 and TGF-b1, overexpressed in pancreatic cancer (PaCa), might start the EMT program. Methods BxPC3 cells were treated with 10 nM S100A8 or S100A9, 0.02 ng/mL TGF-b1 or with vehicle alone (reference) for 72 hours. The expression (mRNA) of Snail, Slug, ZEB1, ZEB2, Twist, CDH1 and CDH2 were quantified by RT-PCR (Light Cycler). N-cadherin protein expression was evaluated by immunohistochemistry (IHC). Results TGF-b1 significantly enhanced the expression of all the tested EMT markers (P=0.037 for CDH1, CDH2, Slug, ZEB1 and ZEB2; P=0.005 for Snail and Twist). S100A8 significantly enhanced the expression levels of Twist (median fold increase: 4, range: 2.6-22.3; P=0.007) while S100A9 did not (median: 2, range: 0.8-9.3, P=0.10). Both molecules reverted TGF-b1 effects on Twist expression (TGF-b1: median: 6, range: 3.6-42.6; TGF-b1 and S100A8: median: 3, range: 2.3-3.8; TGF-b1 and S100A9: median: 3.3, range: 3.1-4.2). By IHC, control cells showed an inhomogeneous non-continuous membranous N-cadherin immunostain. The treatments with both TGF-b1 and S100A8 resulted in an enforced moderate complete membranous immunostain. The combined treatment with TGF-b1 and S100A8 was less effective on protein visualization in comparison to any single treatments (weak to moderate complete immunostain). Conclusion TGF-b1 activate the transcriptional program which underlies the EMT in PaCa cells. A dual role for S100A8 in the EMT was shown: it promotes the EMT by inducing Twist mRNA and N-cadherin protein expression, but it antagonizes TGF-b1 effects on both targets. S100A9 exerts only inhibitory effects on TGF-b1.

description: We study a Casimir-like behaviour in a "deformed QCD". We demonstrate that for the system defined on a manifold of size L the difference Delta E between the energies of a system in a non-trivial background and Minkowski space-time geometry exhibits the Casimir-like scaling Delta E \sim L^{-1}, despite the presence of a mass gap in the system, in contrast with naive expectation Delta E \sim \exp(-m L), which would normally originate from any physical massive propagating degrees of freedom consequent to conventional dispersion relations. The Casimir-like behaviour in our system comes instead from a non-dispersive ("contact") term which is not related to any physical propagating degrees of freedom, such that the naive argument is simply not applicable. These ideas can be explicitly tested in weakly coupled deformed QCD. We comment on profound consequences for cosmology of this effect if it persists in real strongly coupled QCD.

description: Changes in the proportion of children vulnerable on the Early Development Instrument (EDI) over time can be used to identify communities with an improvement or decline in its ability to foster healthy children. Positive change communities had a significant reduction in the proportion of children in a community deemed vulnerable. Negative change communities had a significant increase in the proportion of children in a community deemed vulnerable. Communities exhibiting positive change fell above the 83rd percentile on a composite of those SES variables found to correlate with EDI vulnerability, while negative change communities all fell below the 83rd percentile. Stable communities were those with no significant change in the proportion of children deemed vulnerable, and meaningful differences were found between stable high and stable low vulnerability communities. This community typology provides a priority setting lens for where early child interventions may be most effective. A methodology for identifying and analyzing a group of Early Child Development (ECD) communities is presented. A heat map tool is created to synthesize all data relevant to community ECD. Community stakeholders have to choose and evaluate best practices for providing a stimulating cognitive and social environment for all children before they reach kindergarten. This includes universally targeted variations of pre-kindergarten programs. New Investments would be required, but there would be a financial return to governments in future health, labor, and crime outcomes.

Volodymyr Vynnyčenko as Diarist, Historian and Writer. Literary Narratives of the “Ukrainian Revolution”
Creators: name: Schmid, Ulrich
Publisher: name: Studi Slavistici
Year: 2019

description: Volodymyr Vynnyčenko portrayed the “Ukrainian Revolution” in four different literary genres: in his diary, in an historiographic epic, in a drama, and in a short novel. In each of these representations, another aspect prevails. The diary focuses on Vynnyčenko’s personal role in the Ukrainian nation-building project. The epic endows the failure of the independent Ukrainian state with a historiosophic necessity. The drama translates the social and national dilemmas in Ukraine into a family tragedy. The short novel portrays the hero not as an agent in history, but as an evolving consciousness. Behind all four literary elaborations, a quite heterogeneous mix of philosophical sources can be observed. Vynnyčenko shares with Hegel the belief that every free nation should be in possession of a state. He follows Marx in his economic criticism of capitalist exploitation and his contempt for the bourgeoisie. Finally, he reveres Nietzsche for his concept of the irrational will and his appreciation of ‘great men’ in history. It was clear for Vynnyčenko, that he himself was predestined to play an important role in history. However, he used his historiosophic musings in the four literary genres to prove an essential point: the failure of his Ukrainian project was not his personal shortcoming, but must be ascribed to the belated historical development of the Ukrainian nation.

It is proved that a generalization of a compatibility condition introduced in a previous article is equivalent to the usual shape invariance condition. We focus on the recent examples of Odake and Sasaki (infinitely many polynomial, continuous $l$ and multi-index rational extensions). As a byproduct, we obtain new relations, to the best of our knowledge, for Laguerre, Jacobi polynomials and (confluent) hypergeometric functions.

description: In a companion paper [1], we have presented a cross-correlation approach to near-horizon physics in which bulk dynamics is probed through the correlation of quantities defined at inner and outer spacetime hypersurfaces acting as test screens. More specifically, dynamical horizons provide appropriate inner screens in a 3+1 setting and, in this context, we have shown that an effective-curvature vector measured at the common horizon produced in a head-on collision merger can be correlated with the flux of linear Bondi-momentum at null infinity. In this paper we provide a more sound geometric basis to this picture. First, we show that a rigidity property of dynamical horizons, namely foliation uniqueness, leads to a preferred class of null tetrads and Weyl scalars on these hypersurfaces. Second, we identify a heuristic horizon news-like function, depending only on the geometry of spatial sections of the horizon. Fluxes constructed from this function offer refined geometric quantities to be correlated with Bondi fluxes at infinity, as well as a contact with the discussion of quasi-local 4-momentum on dynamical horizons. Third, we highlight the importance of tracking the internal horizon dual to the apparent horizon in spatial 3-slices when integrating fluxes along the horizon. Finally, we discuss the link between the dissipation of the non-stationary part of the horizon's geometry with the viscous-fluid analogy for black holes, introducing a geometric prescription for a "slowness parameter" in black-hole recoil dynamics.

description: A new full three-body method is introduced to compute the rate of the triple-alpha capture reaction which is the primary source of $^{12}$C in stars. In this work, we combine the Faddeev hyperspherical harmonics and the R-matrix method to obtain a full solution to the three-body $α+α+α$ continuum. Particular attention is paid to the long range effects caused by the pairwise Coulomb interactions. The new rate agrees with the NACRE rate for temperatures greater than 0.07 GK, but a large enhancement at lower temperature is found ($\approx 10^{14}$ at 0.02 GK). Our results are compared to previous calculations where additional approximations were made. We show that the new rate does not significantly change the evolution of stars around one solar mass. In particular, such stars still undergo a red-giant phase consistent with observations, and no significant differences are found in the final white dwarfs.

description: Context IPMNs can be surgically treated or managed conservatively. Objectives To evaluate the effectiveness of the follow-up strategy for IPMN. Methods From January 2003 to June 2012, data regarding 184 patients with IPMNs, as well as type of management (surgery or follow-up), were recorded in a prospective database. Indication to surgery was established according to international consensus guidelines. The patients were divided in three groups: group A (G1), patients with criteria for surgery selected for surgical treatment; group B (G2) patients without criteria for surgery selected for radiological follow-up; group C (G3) patients with criteria for surgery but with high surgical risk selected for radiological follow-up. Failures of our strategy was a pathological diagnosis of benign IPMN in G1 or deaths for malignant IPMN in G2 and in G3. The intention to treat analysis was carried out. Finally we evaluated overall survival (OS) and disease-specific survival (DSS) among the three groups. Results Sex, age and presence of co-morbidities were similar among the three groups. Surgical treatment was proposed in 42 (22.8%) patients (group A). Radiological follow-up was suggested in 142 (77.2 %) patients. Of these, 119 (83.8%) did not present criteria for surgery (group B), while only 23 (16.2%) had one or more criteria (group C). Overall mean follow-up was 30.5±22.4 months. Rate of success was lower in group A than in groups B and C (45.2%, 100%, and 95.7% respectively; P<0.001). Moreover, no patient developed criteria for surgery after a mean follow-up of 28.1±20.0 months in group B. Mean OS was similar among the three groups (36.1±26.3, 28,1±20, 32.8±25.7 months in group A, B and C, respectively) while DSS was lower in group A than in group B and C. Particularly, six patients died for malignant IPMN in group A, none in group B and only one patient in group C (14.2%, 0%, and 4.3%, respectively; P=0.007). Conclusion For patients without criteria of malignancy a follow-up strategy seems effective. Patients with criteria for surgery, without high surgical risk, have to be surgically treated.

description:

The present study, conducted in a secondary school in Perugia (Italy), aimed to verify the benefits of the theatrical teaching methodology on the acquisition of a foreign language, in this case Spanish. The project, funded with the Three-year Plan of the Arts, took place for 20 hours over a school term, involving 23 students in the theatrical teaching group and 30 learners in the control group. The paper describes thoroughly the original experimental protocol in all its different phases, in order to encode it and make it replicable. It also provides the results obtained, measured quantitatively and statistically through the administration of a language pre-test, at the beginning of the project, and a final post-test.

description: Context Pancreatic exocrine insufficiency (PEI) may occur following major pancreatic resection. Objective To demonstrate superior efficacy of pancreatin 25000 minimicrospheres over placebo in treating PEI after pancreatic resection. Patients and Methods A 1-week, double-blind (DB), randomized, placebo-controlled, parallel-group, multicenter study with 1-year open-label extension (OLE). Subjects ³18-year-old with PEI after pancreatic resection, defined as baseline coefficient of fat absorption (CFA) <80%, were randomized to oral pancreatin or placebo (9-15 capsules/day: 3 with main meals, 2 with snacks). In the OLE, all subjects received pancreatin. The primary efficacy measure was least squares (LS) mean CFA change from baseline to end of DB treatment (ANCOVA). Results All 58 subjects randomized (32 pancreatin, 26 placebo) completed the DB phase and entered the OLE; 51 completed the OLE. In the DB phase, the LS mean CFA change was significantly greater with pancreatin vs. placebo: 21.4% (95% CI: 13.7-29.2%) vs. -4.2% (95% CI: -12.8-4.5%); difference 25.6% (95% CI: 13.9-37.3%), P<0.001. In subjects randomized to pancreatin, the mean±SD CFA increase at the end of the OLE was 20.3±24.7%. Treatment-emergent adverse events (TEAEs) occurred in 37.5% subjects on pancreatin and 26.9% on placebo during DB treatment and in 75.9% during the OLE. The most common TEAEs were gastrointestinal disorders (DB: pancreatin 21.9%, placebo 11.5%; OLE: 6.9% patients). Conclusion This study demonstrates superior efficacy of pancreatin 25000 over placebo in patients with PEI after major pancreatic resection, as measured by change in CFA, with an expected safety and tolerability profile at the dosage administered.

description: Context For patients with borderline resectable pancreatic cancer, the benefit of neoadjuvant therapy remains to be defined. Objective We did a systematic search of the literature on this topic. Methods Prospective studies, where chemotherapy, irrespective of regimen, in combination with radiotherapy was given before surgery to patients with borderline resectable cancer, were analyzed by a meta-analytical method. Primary outcome was tumor response; surgical exploration rate, resection rate, therapy-induced toxicity, and survival were secondary outcomes. Data were expressed as weighted pooled proportions with 95% confidence interval (95% CI). Results Eleven studies with 247 participants were included. Three were phase I/II trials, 3 phase II, and 5 prospective cohort studies. The complete/partial response rate was 17.1% (95% CI: 10-26%). Stable and progressive disease were 61.4% (95% CI: 51-70%) and 24.3% (95% CI: 16-33%), respectively. Treatment-related grade 3-4 toxicity was 34.6% (95% CI: 24-46%). At restaging following neoadjuvant therapy, 67.5% of patients (95% CI: 54-78%) underwent surgery, and 80.3% of them (95% CI: 67-88%) underwent resection. R0 resections amounted to 82.1% (95% CI: 74-88%). Estimated 1- and 2-year survival probabilities after resection were 52.1% (95% CI: 33-70%) and 44.9% (95% CI: 21-71%), respectively. Conclusion Our data cast some concern on the value of neoadjuvant therapy for patients with borderline resectable pancreatic cancers: if the intent of therapy were to induce tumor shrinkage and to allow curative surgery, this is only accomplished in one out of 7 patients; moreover, two thirds of patients could have been explored at their initial presentation, as they underwent surgery despite an unsuccessful response to therapy. The only benefit of this approach seems to be sparing surgery for patients with progressive disease.

description: The renormalization group framework can be applied to Quantum Field Theory on curved space-time, but there is no proof whether the beta-function of the gravitational coupling indeed goes to zero in the far infrared or not. In a recent paper we have shown that the amount of dark matter inside spiral galaxies may be negligible if a small running of the General Relativity coupling G is present. Here we extend the proposed model to elliptical galaxies and present a detailed analysis on the modeling of NGC 4494 (an ordinary elliptical) and NGC 4374 (a giant elliptical). In order to compare our results to a well known alternative model to the standard dark matter picture, we also evaluate NGC 4374 with MOND. In this galaxy MOND leads to a significative discrepancy with the observed velocity dispersion curve and has a significative tendency towards tangential anisotropy. On the other hand, the approach based on the renormalization group and general relativity (RGGR) could be applied with good results to these elliptical galaxies and is compatible with lower mass-to-light ratios (of about the Kroupa IMF type).

description: Context The Atlanta definition of acute pancreatitis (AP) severity are based on empiric description of occurrences that are merely associated with severity, so resulting in a suboptimal assessment. Objective To develop a new classification of AP severity on the basis of a sound conceptual framework, comprehensive review of published evidence, and worldwide consultation. Methods Invitation to contribute to the development of a new classification of AP severity was sent to all surgeons, gastroenterologists, internists, intensivists, and radiologists who are currently active in the field of clinical AP. A global web-based survey was conducted and a dedicated international symposium was organized to bring contributors from different disciplines together and discuss the concept and definitions. Results The new classification of AP severity is based on the actual local and systemic determinants of severity. The “local determinants” relates to whether there is (peri)pancreatic necrosis or not, and if present whether it is sterile or infected. The “systemic determinants” relates to whether there is organ failure or not, and if present whether it is transient or persistent. The presence of a determinant can modify the effect of another such that the presence of both infected (peri)pancreatic necrosis and persistent organ failure has a greater effect on severity than either alone. The derivation of a classification based on the above principles results in four categories of severity: “mild”, “moderate”, “severe”, and “critical”. Conclusion This classification is the result of a consultative process amongst pancreatologists from 49 countries. It provides a set of concise up-to-date definitions of all the main entities pertinent to classifying the severity of AP in clinical practice and research. This ensures that the “Determinant-Based Classification” can be used in a uniform manner through the world.
