Avaluació del programa de tractament d’agressors domèstics

La violència de gènere constitueix en els nostres dies una problemàtica amb un fort impacte social. Els mitjans de comunicació han augmentat la conscienciació ciutadana fent palès les greus conseqüències que pot tenir aquest tipus de violència. Davant aquesta realitat, la societat ha manifestat la seva preocupació i demanda de solucions. Dintre de les possibles mesures considerades, la investigació internacional a posat de manifest la rellevància d’intervenir no només amb les víctimes sinó també amb els agressors, ja que un alt nombre d’aquestes reprenen la convivència amb el seu agressor. En aquest sentit, les mesures penals han de tenir un component rehabilitador i de reinserció social. En el context penitenciari, el manament constitucional impregna de sentit els programes de tractament psicològics amb agressors domèstics. Per aquest motiu, l’objectiu d’aquest estudi és avaluar l’eficàcia del programa de tractament d’agressors domèstics que s’ha dut a terme al Centre Penitenciari Quatre Camins (Barcelona) durant el període 2006-2007. Per a la consecució d’aquest objectiu s’han avaluat diverses variables psicològiques (distorsions cognitives, impulsivitat, empatia, ira, motivació terapèutica, etc.), les quals són objecte de modificació per part de la intervenció. El disseny de la investigació consisteix en una comparació entre un grup de subjectes que ha rebut tractament (Grup Tractament) i un grup de subjectes que, per raons alienes al rebuig, no han estat tractats (Grup Control). Aquest estudi constitueix una investigació pilot i pionera a Catalunya en l’àmbit del tractament dels agressors domèstics. La principal conclusió d’aquest estudi és que el programa de tractament amb agressors domèstics rep un suport parcial de les dades empíriques obtingudes.

Identification and analysis of functional elements in 1% of the human genome by the ENCODE pilot project.

We report the generation and analysis of functional data from multiple, diverse experiments performed on a targeted 1% of the human genome as part of the pilot phase of the ENCODE Project. These data have been further integrated and augmented by a number of evolutionary and computational analyses. Together, our results advance the collective knowledge about human genome function in several major areas. First, our studies provide convincing evidence that the genome is pervasively transcribed, such that the majority of its bases can be found in primary transcripts, including non-protein-coding transcripts, and those that extensively overlap one another. Second, systematic examination of transcriptional regulation has yielded new understanding about transcription start sites, including their relationship to specific regulatory sequences and features of chromatin accessibility and histone modification. Third, a more sophisticated view of chromatin structure has emerged, including its inter-relationship with DNA replication and transcriptional regulation. Finally, integration of these new sources of information, in particular with respect to mammalian evolution based on inter- and intra-species sequence comparisons, has yielded new mechanistic and evolutionary insights concerning the functional landscape of the human genome. Together, these studies are defining a path for pursuit of a more comprehensive characterization of human genome function.

Research needs in allergy: an EAACI position paper, in collaboration with EFA.

In less than half a century, allergy, originally perceived as a rare disease, has become a major public health threat, today affecting the lives of more than 60 million people in Europe, and probably close to one billion worldwide, thereby heavily impacting the budgets of public health systems. More disturbingly, its prevalence and impact are on the rise, a development that has been associated with environmental and lifestyle changes accompanying the continuous process of urbanization and globalization. Therefore, there is an urgent need to prioritize and concert research efforts in the field of allergy, in order to achieve sustainable results on prevention, diagnosis and treatment of this most prevalent chronic disease of the 21st century.The European Academy of Allergy and Clinical Immunology (EAACI) is the leading professional organization in the field of allergy, promoting excellence in clinical care, education, training and basic and translational research, all with the ultimate goal of improving the health of allergic patients. The European Federation of Allergy and Airways Diseases Patients' Associations (EFA) is a non-profit network of allergy, asthma and Chronic Obstructive Pulmonary Disorder (COPD) patients' organizations. In support of their missions, the present EAACI Position Paper, in collaboration with EFA, highlights the most important research needs in the field of allergy to serve as key recommendations for future research funding at the national and European levels.Although allergies may involve almost every organ of the body and an array of diverse external factors act as triggers, there are several common themes that need to be prioritized in research efforts. As in many other chronic diseases, effective prevention, curative treatment and accurate, rapid diagnosis represent major unmet needs. Detailed phenotyping/endotyping stands out as widely required in order to arrange or re-categorize clinical syndromes into more coherent, uniform and treatment-responsive groups. Research efforts to unveil the basic pathophysiologic pathways and mechanisms, thus leading to the comprehension and resolution of the pathophysiologic complexity of allergies will allow for the design of novel patient-oriented diagnostic and treatment protocols. Several allergic diseases require well-controlled epidemiological description and surveillance, using disease registries, pharmacoeconomic evaluation, as well as large biobanks. Additionally, there is a need for extensive studies to bring promising new biotechnological innovations, such as biological agents, vaccines of modified allergen molecules and engineered components for allergy diagnosis, closer to clinical practice. Finally, particular attention should be paid to the difficult-to-manage, precarious and costly severe disease forms and/or exacerbations. Nonetheless, currently arising treatments, mainly in the fields of immunotherapy and biologicals, hold great promise for targeted and causal management of allergic conditions. Active involvement of all stakeholders, including Patient Organizations and policy makers are necessary to achieve the aims emphasized herein.

Rotaviruses as a cause of nosocomial, infantile diarrhoea in Northern Brazil: pilot study

Faecal samples were obtained from 190 children, aged 0 to 5 years, admitted to a public hospital in Belém, Pará, Brazil. These patients were placed in a pediatric ward with 40 beds distributed in six rooms. Case were classified into three groups: (a) nosocomial: children who developed gastroenteritis 72 hr or later after admission; (b) community-acquired: patients admitted either with diarrhoea or who had diarrhoea within 72 hr following admission; (c) non-diarrhoeic: those children who had no diarrhoea three days before and three days after collection of formed faecal sample. Specimens were routinely processed for the presence of rotaviruses, bacteria and parasites. Rotaviruses were detected through enzyme-linked immunosorbent assay (ELISA) and subsequently serotyped/electrophoretyped. Rotaviruses were the most prevalent enteropathogens among nosocomial cases, accounting for 39 % (9/23) of diarrhoeal episodes; on the other hand, rotaviruses ocurred in 8.3 % (11/133) and 9 % (3/34) of community-acquired and non-diarrhoeic categories, respectively. Mixed infections involving rotavirus and Giardia intestinalis and rotavirus plus G. intestinalis and Entamoeba histolytica were detected in frequencies of 8.6 and 4.3 %, respectively, in the nosocomial group. The absence of bacterial pathogens in this category, and the unusual low prevalence of these agents in the other two groups may reflect the early and routine administration of antibiotics following admission to this hospital. Rotavirus serotype 2 prevailed over the other types, accounting for 77.8 % of isolates from nosocomial diarrhoeal episodes. In addition, at least five different genomic profiles could be observed, of which one displayed an unusual five-segment first RNA cluster. Dehydration was recorded in all cases of hospital-acquired, rotavirus-associated diarrhoea, whereas in only 57 % of nosocomial cases of other aetiology. It was also noted that nosocomial, rotavirus-associated diarrhoeal episodes occur earlier (7 days), following admission, if compared with those hospital-acquired cases of other aetiology (14 days).

Second-hand tobacco smoke in prison: tackling a public health matter through research.

OBJECTIVES: This action-research study conducted in a Swiss male post-trial detention centre (120 detainees and 120 staff) explored the attitudes of detainees and staff towards tobacco smoking. Tackling public health matters through research involving stakeholders in prisons implies benefits and risks that need exploration. STUDY DESIGN: The observational study involved multiple strands (quantitative and qualitative components, and air quality measurements). This article presents qualitative data on participants' attitudes and expectations about research in a prison setting. METHODS: Semi-structured interviews were used to explore the attitudes of detainees and staff towards smoking before and after a smoke-free regulation change in the prison in 2009. Specific coding and thematic content analysis for research were performed with the support of ATLAS.ti. RESULTS: In total, 77 interviews were conducted (38 before the regulation change and 39 after the regulation change) with 31 detainees (mean age 35 years, range 22-60 years) and 27 prison staff (mean age 46 years, range 29-65 years). Both detainees and staff expressed satisfaction regarding their involvement in the study, and wished to be informed about the results. They expected concrete changes in smoke-free regulation, and that the research would help to find ways to motivate detainees to quit smoking. CONCLUSION: Active involvement of stakeholders promotes public health. Interviewing detainees and prison staff as part of an action-research study aimed at tackling a public health matter is a way of raising awareness and facilitating change in prisons. Research needs to be conducted independently from the prison administrators in order to increase trust and to avoid misunderstandings.

A research agenda for malaria eradication: vaccines.

Vaccines could be a crucial component of efforts to eradicate malaria. Current attempts to develop malaria vaccines are primarily focused on Plasmodium falciparum and are directed towards reducing morbidity and mortality. Continued support for these efforts is essential, but if malaria vaccines are to be used as part of a repertoire of tools for elimination or eradication of malaria, they will need to have an impact on malaria transmission. We introduce the concept of "vaccines that interrupt malaria transmission" (VIMT), which includes not only "classical" transmission-blocking vaccines that target the sexual and mosquito stages but also pre-erythrocytic and asexual stage vaccines that have an effect on transmission. VIMT may also include vaccines that target the vector to disrupt parasite development in the mosquito. Importantly, if eradication is to be achieved, malaria vaccine development efforts will need to target other malaria parasite species, especially Plasmodium vivax, where novel therapeutic vaccines against hypnozoites or preventive vaccines with effect against multiple stages could have enormous impact. A target product profile (TPP) for VIMT is proposed and a research agenda to address current knowledge gaps and develop tools necessary for design and development of VIMT is presented.

Data bases for the assessment of medical technologies: examples from Europe.

The assessment of medical technologies has to answer several questions ranging from safety and effectiveness to complex economical, social, and health policy issues. The type of data needed to carry out such evaluation depends on the specific questions to be answered, as well as on the stage of development of a technology. Basically two types of data may be distinguished: (a) general demographic, administrative, or financial data which has been collected not specifically for technology assessment; (b) the data collected with respect either to a specific technology or to a disease or medical problem. On the basis of a pilot inquiry in Europe and bibliographic research, the following categories of type (b) data bases have been identified: registries, clinical data bases, banks of factual and bibliographic knowledge, and expert systems. Examples of each category are discussed briefly. The following aims for further research and practical goals are proposed: criteria for the minimal data set required, improvement to the registries and clinical data banks, and development of an international clearinghouse to enhance information diffusion on both existing data bases and available reports on medical technology assessments.

Projecte pilot d'innovació docent de l'assignatura Estructura de Computadors I

L'objectiu del projecte ha estat la millora de la qualitat docent de l'assignatura Estructura de Computadors I, impartida a la Facultat d'Informàtica de Barcelona (UPC) dins els estudis d'Enginyeria Informàtica, Enginyeria Tècnica en Informàtica de Sistemes i Enginyeria Tècnica en Informàtica de Gestió. S'ha treballat en quatre línies d'actuació: (i) aplicació de tècniques d'aprenentatge actiu a les classes; (ii) aplicació de tècniques d'aprenentage cooperatiu no presencials; (iii) implantació de noves TIC i adaptació de les ja emprades per tal d'habilitar mecanismes d'autoavaluació i de realimentació de la informació referent a l'avaluació; i (iv) difusió de les experiències derivades de les diferents actuacions. Referent a les dues primeres mesures s'avalua l'impacte de metodologies docents que afavoreixen l'aprenentatge actiu tant de forma presencial com no presencial, obtenint-se clares millores en el rendiment respecte a altres metodologies utilitzades anteriorment enfocades a la realització de classes del tipus magistral, en què únicament es posa a l'abast dels alumnes la documentació de l'assignatura per a què puguin treballar de forma responsable. Les noves metodologies fan especial èmfasi en el treball en grup a classe i la compartició de les experiències fora de classe a través de fòrums de participació. La mesura que ha requerit més esforç en aquest projecte és la tercera, amb el desenvolupament d'un entorn d'interfície web orientat a la correcció automàtica de programes escrits en llenguatge assemblador. Aquest entorn permet l'autoavaluació per part dels alumnes dels exercicis realitzats a l'assignatura, amb obtenció d'informació detallada sobre les errades comeses. El treball realitzat dins d'aquest projecte s'ha publicat en congressos rellevants en l'àrea docent tant a nivell estatal com internacional. El codi font de l'entorn esmentat anteriorment es posa a disposició pública a través d'un enllaç a la web.

High altitude, a natural research laboratory for the study of cardiovascular physiology and pathophysiology.

High altitude constitutes an exciting natural laboratory for medical research. Although initially, the aim of high-altitude research was to understand the adaption of the organism to hypoxia and find treatments for altitude-related diseases, during the past decade or so, the scope of this research has broadened considerably. Two important observations led the foundation for the broadening of the scientific scope of high-altitude research. First, high-altitude pulmonary edema represents a unique model that allows studying fundamental mechanisms of pulmonary hypertension and lung edema in humans. Second, the ambient hypoxia associated with high-altitude exposure facilitates the detection of pulmonary and systemic vascular dysfunction at an early stage. Here, we will review studies that, by capitalizing on these observations, have led to the description of novel mechanisms underpinning lung edema and pulmonary hypertension and to the first direct demonstration of fetal programming of vascular dysfunction in humans.

Desenvolupament de problemes virtuals i interactius per a l’aprenentatge de la Microbiologia

La finalitat del projecte ha estat desenvolupar un espai virtual teòric-pràctic per a l’aprenentatge de la Microbiologia. Aquest espai virtual, basat en l'aprenentatge a través de problemes, s’ha anomenat “Microbiologia Interactiva” i proposa a l’alumne les següents àrees temàtiques: Introducció a les tècniques de la Microbiologia; Estructura i funció de la cèl.lula microbiana; Creixement i control microbià; Microbiologia molecular; Fisiologia i metabolisme microbians; Virologia; Ecologia Microbiana; Diversitat microbiana. Per a cada temàtica s’han definit unes competències a assolir a través de la resolució de problemes teòrics o pràctics. En aquest darrer cas, se li proposa a l’alumne que entri en el laboratori virtual per a la resolució dels casos pràctics plantejats. A més, per a la resolució dels problemes, l’alumne disposa d’un seguit de recursos per a cada temàtica. Finalment, també s’inclouen activitats de relació i d’ampliació per tal d’estimular la discussió, l’esperit crìtic, el treball en grup i la recerca bibliogràfica. A més, per tal de facilitar el seu ús, el web disposa també d'un tutorial. El web “Microbiologia Interactiva” es va introduir de forma pilat en l’ensenyament de l'assignatura de Microbiologia de la Llicenciatura de Biologia i de la de Microbiologia I de la llicenciatura de Biotecnologia de la Universitat Autònoma de Barcelona (UAB) durant el curs 2007-08. Al llarg d'aquest curs es va valorar la seva utilitat i acceptació per part dels alumnes mitjançant enquestes. Els bons resultats obtinguts van aconsellar que aquesta eina fora ja utilitzada en totes les assignatures generals de Microbiologia de les llicenciatures de Biologia, Biotecnologia, Bioquímica, Química, Enginyeria Química, Ciències Ambientals i Ciència i Tecnologia dels Aliments de la UAB. Actualment el web s’està també utilitzant amb molt bons resultats a les assignatures de Microbiologia dels nous graus que ofereix la Facultat de Biociències de la UAB. Així doncs, en aquest projecte s’han assolit amb escreix els objectius previstos. Es pot consultar el web desenvolupat a l’adreça http://microbiologia.uab.cat//Microbiologia_Interactiva_Web/.
