El carácter como predictor de trastornos de la personalidad en adictos: la tipología caracterial de Cloninger y su abordaje psicosocial
2007
El presente estudio aborda las relaciones de las dimensiones caracteriales del modelo de Cloninger con los trastornos de la personalidad. Se obtiene una muestra de sujetos (N=565) que inician tratamiento por conductas adictivas en un centro ambulatorio (CAD 4 San Blas, Instituto de Adicciones, Madrid Salud), y cumplimentan el TCI-R, el MCMI-II, el VIP y el CCE-R. Según los criterios de Cloninger y, mediante análisis discriminante, son clasificados en los diferentes tipos caracteriales. Se comparan éstos con los encontrados en una muestra de población general (N=114), encontrándose que mientras en éste grupo predomina el tipo Equilibrado, en el grupo de adictos predominan los tipos Desorgani…
The Relationship Between Goal Orientation, Social Comparison Responses, Self-Efficacy, and Performance
2008
The present study examined whether social comparison responses (identification and contrast in social comparison) mediated the relationship between goal orientation (promotion and prevention) and self-efficacy, and whether self-efficacy was subsequently related with a better performance. As expected, the results showed that promotion-oriented individuals – who are focused on achieving success – had higher self-efficacy than prevention-oriented individuals – who are focused on avoiding failure. Only one of the social comparison responses had a mediating role. That is, the tendency to contrast oneself with others who were doing better mediated the relationship between a prevention goal orien…
Global diversity in the TAS2R38 bitter taste receptor: revisiting a classic evolutionary PROPosal
2016
AbstractThe ability to taste phenylthiocarbamide (PTC) and 6-n-propylthiouracil (PROP) is a polymorphic trait mediated by the TAS2R38 bitter taste receptor gene. It has long been hypothesized that global genetic diversity at this locus evolved under pervasive pressures from balancing natural selection. However, recent high-resolution population genetic studies of TAS2Rs suggest that demographic events have played a critical role in the evolution of these genes. We here utilized the largest TAS2R38 database yet analyzed, consisting of 5,589 individuals from 105 populations, to examine natural selection, haplotype frequencies and linkage disequilibrium to estimate the effects of both selectio…
Entre Trapani et Tunis. De la période du Risorgimento à la fin du Protectorat français: parcours de travailleurs et d’entrepreneurs au-delà du Canal …
2019
Sin dai tempi più antichi, il Canale di Sicilia e la città di Trapani hanno costituito un ponte naturale fra il Maghreb e la Sicilia. Il saggio mette a sistema alcuni studi sugli architetti ed imprenditori di origine trapanese che emigrarono in Tunisia fra il XVIII e XIX secolo e ne propone una lettura inedita. Il fil rouge che lega Giuseppe Abita, la famiglia di imprenditori Canino e Domenico Basciano riguarda sia la loro provenienza dalla città siciliana, ma soprattutto l'importante contributo che essi hanno trasferito nell'architettura del periodo coloniale e post-coloniale francese nel Maghreb.
Predictive distributions that mimic frequencies over a restricted subdomain
2020
A predictive distribution over a sequence of $$N+1$$ events is said to be “frequency mimicking” whenever the probability for the final event conditioned on the outcome of the first N events equals the relative frequency of successes among them. Exchangeable distributions that exhibit this feature universally are known to have several annoying concomitant properties. We motivate frequency mimicking assertions over a limited subdomain in practical problems of finite inference, and we identify their computable coherent implications. We provide some examples using reference distributions, and we introduce computational software to generate any complete specification desired. Theorems on reducti…
Laparoscopic approach in abdominal emergencies: a 5-year experience at a single center.
2012
Background. Laparoscopy is ever more common in both elective and emergency surgery. In fact, in abdominal emergencies it enables the resolution of preoperative diagnostic doubts as well as treatment of the underlying disease. We present a retrospective study of the results of a 5-year experience at a single center. Patients and methods. Between September 2006 and August 2011, 961 patients were treated via laparoscopy, including 486 emergency cases (15 gastroduodenal perforation; 165 acute cholecystitis; 255 acute appendicitis; 15 pelvic inflammatory disease and non-specific abdominal pain [NSAP]; 36 small bowel obstruction). All procedures were conducted by a team trained in laparoscopic su…
Intestinal tuberculosis in a child living in a country with a low incidence of tuberculosis : a case report
2014
Background: Relatively common in adults, intestinal tuberculosis is considered rare in children and adolescents. The protean manifestations of intestinal tuberculosis mean that the diagnosis is often delayed (sometimes even for years), thus leading to increased mortality and unnecessary surgery. The main diagnostic dilemma is to differentiate intestinal tuberculosis and Crohn’s disease because a misdiagnosis can have dramatic consequences. Case presentation: A 13-year-old Caucasian, Italian female adolescent attended the Emergency Department complaining of abdominal pain, a fever of up to 38°C, night sweats, diarrhea with blood in stool, and a weight loss of about three kilograms over the p…
NEW THERAPEUTIC PERSPECTIVES IN IRRITABLE BOWEL SYNDROME: TARGETING LOW-GRADE INFLAMMATION, IMMUNO-NEUROENDOCRINE AXIS, MOTILITY, SDECRETION AND BEYO…
2017
Irritable bowel syndrome (IBS) is a chronic, recurring, and remitting functional disorder of the gastrointestinal tract characterized by abdominal pain, distention, and changes in bowel habits. Although there are several drugs for IBS, effective and approved treatments for one or more of the symptoms for various IBS subtypes are needed. Improved understanding of pathophysiological mechanisms such as the role of impaired bile acid metabolism, neurohormonal regulation, immune, dysfunction, the epithelial barrier and the secretory properties of the gut has led to advancements in the treatment of IBS. With regards to therapies for restoring intestinal permeability, multiple studies with prebiot…
Biocrusts and catchment asymmetry in Tabernas Desert (Almeria, Spain)
2022
Abstract Catchment asymmetry is a fairly frequent phenomenon on a global scale but the main causes leading to its formation are still not well understood. Where the intervention of structural or tectonic causes is not relevant, asymmetry seems to result from differential erosion between opposite slopes that flow into the same channel, which is frequently associated with contrasted biocrust and/or vegetation covers. Biocrusts are known to be important surface stabilizing agents. However, their geomorphological consequences at the landscape scale are little known. In this study we combined field measurements with digital elevation models and image analysis to determine whether catchment asymm…
The Intention-to-Treat Effect of Bridging Treatments in the Setting of Milan Criteria–In Patients Waiting for Liver Transplantation
2019
In patients with hepatocellular carcinoma (HCC) meeting the Milan criteria (MC), the benefit of locoregional therapies (LRTs) in the context of liver transplantation (LT) is still debated. Initial biases in the selection between treated and untreated patients have yielded conflicting reported results. The study aimed to identify, using a competing risk analysis, risk factors for HCC-dependent LT failure, defined as pretransplant tumor-related delisting or posttransplant recurrence. The study was registered at www.clinicaltrials.gov (identification number NCT03723304). In order to offset the initial limitations of the investigated population, an inverse probability of treatment weighting (IP…
