Methodology for a Study of the Perceived Quality of Public Transport in Santander

ABSTRACT:This article will primarily deal with improving the quality of a public transport system through the study of the main variables that influence the perceived quality by users, in other words a methodology for modeling the quality of bus services in the Spanish city of Santander, supported by user perception data. The models calibrated to study the quality of public transport perceived by users are firstly obtained by estimating all the different service attributes, considering mean users’ perceptions through an Ordered Probit model, and then studying random variations in users’ tastes, applying an Ordered Probit model with random parameters. The models represent the process of quality evaluation based on a limited group of predefined variables. The choice of these variables is important because they are used to explain the selection process to be modeled. The collected data are analyzed and modeled to check the validity of the different variables. Main results suggest consumers would be willing to pay a higher price for improved transport connection networks including the supply of clearer information and the attention to consumer’s complaints. Ticket price is also an important attribute mainly for frequent bus users.This work was made possible thanks to a grant from the Spanish Ministerio de Economía y Competitividad with additional financing from FEDER funds to the project TRA2012-37659

Mastocytosis: One Word for Different Diseases

Abstract Mastocytosis is a neoplastic disease originating from tissue infiltration by transformed mast cells. The diagnosis requires a high grade of suspicion due to the large variety of presenting symptoms. The World Health Organization classification recognizes localized (cutaneous) and systemic forms of the disease, with these forms showing different degrees of aggressiveness. Mastocytosis is often a multiorgan disease, and its correct management requires a multidisciplinary team of experienced consultants to provide overall patient care. Bone marrow evaluation by molecular analyses, skeleton X-ray and abdominal scan together with allergologic and dermatologic evaluation constitute the essential diagnostic work-up for adult patients with mastocytosis. As clinical situations vary, treatment options range from the use of drugs to treat the symptoms, such as anti-H1 receptors and steroids, to UV irradiation, which is overwhelmingly used in patients with cutaneous mastocytosis (CM) or indolent systemic mastocytosis, to cytoreductive treatment to control life-threatening symptoms or organ damage in the more aggressive forms of the disease. Prognosis also widely differs among patients diagnosed with mastocytosis, with the spectrum ranging from an almost normal life expectancy for those with CM and to less than 1-year median overall survival for those with mast cell leukemia

Design/methodology/approach – The consensus was derived through a Delphi-type series of questions in an open forum of academics and industrialists across Europe. Findings – The consensus reached was of the proven benefits of electronic platforms for small businesses and the need for further research to assess how small businesses can incorporate electronic traceability and supply chain management systems into their existing operations. Practical implications – Electronic platforms are spreading rapidly in the food industry. However, there is some concern that small businesses are not aware of the potential for electronic supply chains such as the potential that electronic traceability offers smaller networks to supply highly demanded food quality attributes such as organic production and regional foods. Originality/value – The paper addresses the highly topical issue of food origin with a new approach to the supply technologies behind the product.EC/FP6/7124/EU/E-PLATFORM TECHNOLOGIES FOR THE EUROPEAN AGRO-FOOD SUPPLY CHAIN/E-MENS

Presence of Anagrus flaveolus in Argentina, parasitoid of an insect injurious to wheat and corn (Insecta - hymenoptera - mymaridae)

Lo hemos criado a partir de posturas de Delphacodes hay ward i Muir, 1929, depositadas en plantas de trigo (Tritricum aestivum L.). En la presente contribución se evaluó el porcentaje de parasitoidismo de esta especie en campos de trigo sobre los huevos del delfácido antes mencionado y el mismo parámetro fue medido en condiciones de laboratorio. Se registró la duración de su ciclo de vida y se realizaron pruebas para observar su comportamiento frente a posturas de otros homópteros auquenorrincos, de ellas se comprobó que A. flaveolus parasitoidiza en condiciones de laboratorio a los huevos de Amplicephalus simpliciusculus Linnavouri,1995 (Homóptera - Deltocephalinae).The widespread mymarid species Anagrus flaveolus Waterhouse, 1913 is recorded from Argentina for the first time. It was found parasitoidizing eggs of the planthopper Delphacodes haywardi Muir, 1929, laid in wheat plants (Triticum aestivum L.) in Buenos Aires Province. The parasitoidism percentage has been evaluated under field conditions in wheat crops, on eggs of the planthopper cited above. This same parameter has been measured in reared specimens under laboratory conditions, recording the life-cicle duration. Different essays have been carried out in order to determinate its preference behaviour when placed whit two cicadelis species: Syncharina punctantissima (Signoret, 1854) and Plesiomatta mollicella (Fowler, 1900) and two leafhoppers: Exitianus obscurinervis (Stal, 1859) and Amplicephlus simpliciusculus Linnavuori, 1995; this resulted in a strong prefernce for eggs of A. simpliciusculus, from which imagoes were obtained.Facultad de Ciencias Naturales y Muse

an outbreak of severe invasive meningococcal disease due to a capsular switched neisseria meningitidis hypervirulent strain b cc11

Abstract Objectives The aim was to investigate an outbreak of invasive meningococcal disease (IMD) in Southern Sardinia. Methods Epidemiological and microbiological investigations were performed. The latter included antimicrobial susceptibility testing and whole-genome sequencing (WGS). Results Seven individuals with severe IMD were found to be infected with serogroup B (MenB) Neisseria meningitidis in the first quarter of 2018. Five of the seven cases (five males; mean age 19 years; range 18–21 years; CFR 40%) were due to a unique strain B:P1.5-1,10-8:F3-6:ST-11(cc11), probably switched from the hypervirulent C-cc11, as confirmed by WGS. All five patients had attended the same nightclub in the 2 weeks prior to symptom onset. Public health measures, including chemoprophylaxis of contacts and active immunization against MenB, were implemented. Conclusions We observed five IMD cases due to the same switched MenB strain. The hypervirulent B:P1.5-1,10-8:F3-6:ST-11(cc11) strain, probably switched from C-cc11, is of concern due to the observed high virulence and case fatality rates. All the patients shared the same place of probable exposure. The molecular characterization of the invasive strain allowed the outbreak to be confirmed, which was then controlled through timely public health action

Anti-PD1 Consolidation in Patients with Hodgkin Lymphoma at High Risk of Relapse after Autologous Stem Cell Transplantation: A Multicenter Real-Life Study

(1) Background: Consolidation therapy is an emerging strategy for patients with relapsed/refractory (RR) Hodgkin Lymphoma (HL) at high risk of failing salvage autologous stem cell transplantation (ASCT). (2) Objectives: To assess the safety and effectiveness of PD1-blockade consolidation for these high-risk patients. (3) Design: Multi-center retrospective analysis. (4) Methods: We identified 26 patients given anti-PD1 consolidation, from June 2016 to May 2020. (5) Results: Patients displayed the following risk factors: refractory disease (69%), relapse 3, occurred in 12 patients (46.15%) and mainly included skin rashes (41.7%), transaminitis (33.3%), and thyroid hypofunction (25%). Patients completed a median of 13 courses (range 6–30). At a median follow-up of 25.8 months post-ASCT, the median progression-free (PFS) was 42.6 months, with a 2-year PFS and overall survival rates of 79% and 87%, respectively. (6) Conclusions: Post-ASCT consolidation with anti-PD1 is feasible and effective. Further studies are warranted to define the optimal treatment length and patients’ subsets more likely to benefit from this approach

West Nile virus transmission. results from the integrated surveillance system in Italy, 2008 to 2015

IIn Italy a national Plan for the surveillance of imported and autochthonous human vector-borne diseases (chikungunya, dengue, Zika virus disease and West Nile virus (WNV) disease) that integrates human and veterinary (animals and vectors) surveillance, is issued and revised annually according with the observed epidemiological changes. Here we describe results of the WNV integrated veterinary and human surveillance systems in Italy from 2008 to 2015. A real time data exchange protocol is in place between the surveillance systems to rapidly identify occurrence of human and animal cases and to define and update the map of affected areas i.e. provinces during the vector activity period from June to October. WNV continues to cause severe illnesses in Italy during every transmission season, albeit cases are sporadic and the epidemiology varies by virus lineage and geographic area. The integration of surveillance activities and a multidisciplinary approach made it possible and have been fundamental in supporting implementation of and/or strengthening preventive measures aimed at reducing the risk of transmission of WNV trough blood, tissues and organ donation and to implementing further measures for vector control
