Les limitacions en la capacitat d'emmagatzemament dels dispositius sensors sense fils o motes és consubstancial al seu disseny, però pot convertir-se en un problema en determinades situacions. Aquest projecte de fi de carrera ha esta motivat per l'interès en superar aquestes limitacions en una situació concreta: una mota dedicada a prendre mostres amb alguns dels seus sensors que passa un període llarg de temps sense poder comunicar amb la base. Per aconseguir aquest objectiu s'ha dissenyat i implementat un sistema que comprimeix les mostres en una mota només quan l'espai d'emmagatzemament està pròxim a exhaurir-se. Aquest procés de compressió pot repetir-se indefinidament i cada vegada que actua elimina només les mostres menys significatives, tot preservant la freqüència del mostreig.A continuació es descriu l'algorisme que s'ha dissenyat, respectuós amb les capacitats de processament de la mota, la implementació que s'ha fet en nesC per a una mota Cou24 amb TinyOS, el programari complementari que s'ha desenvolupat en Java per a PC, i el resultat de les proves que s'han fet de tot aquest conjunt.

En el marc d'una escola inclusiva, es busca promoure l'aprenentatge de tots els alumnes. L'alumnat amb Trastorn de l'Espectre Autista (TEA) forma part de la diversitat que ha d'atendre el professorat, un alumnat que presenta dificultats d'interacció social i de comprensió dels estats mentals dels altres, aspectes que influeixen en la seva qualitat de vida. D'aquesta manera, es presenta una intervenció que busca afavorir el desenvolupament de les capacitats relacionals, comunicatives i simbòliques dels alumnes TEA. La intervenció té en compte l'enfocament interactiu i contextual del procés de valoració proposat per Ángel Rivière (2001), la Teoria de la Ment desenvolupada per Baron-Cohen, Leslie i Firth el 1985 i el programa DIR o Floortime d'Stanley Greenspan. A més, s'han elaborat una sèrie de materials i activitats per a l'ensenyament de la comprensió de les emocions i de les habilitats socials, basades en les aportacions de Howling, Baron-Cohen i Hadwin (2006) i les historietes socials de Gray.

En aquest article s'aporten proves de l'impacte positiu que té l'aplicació de les tecnologies de la informació i la comunicació (TIC) en l'empresa turística catalana. La transcendència que en els darrers anys ha adquirit el mercat turístic català en el context europeu el converteix en un laboratori d'anàlisi idoni per al sector. Els resultats obtinguts posen de manifest que l'ús d'aquestes tecnologies s'acompanya d'un major grau d'internacionalització de l'empresa, el desenvolupament de canvis organitzatius i la implantació de noves estratègies competitives, cosa que dóna lloc a un model de negoci allunyat de les concepcions tradicionals del sector. A més, l'ús estratègic de les TIC afavoreix l'ús de mà d'obra més qualificada, un servei més personalitzat i una major proximitat a proveïdors i distribuïdors. Tanmateix, és en el procés d'innovació empresarial on l'impacte positiu de les TIC és percep més, atès que el seu ús ha contribuït a superar alguns dels obstacles existents, a interioritzar el procés en el si de l'empresa i a fer més partícips els mateixos treballadors, i això ha donat com a resultat una àmplia diversitat d'innovacions de tota mena (de producte, de procés i organitzatives). La participació en xarxes de cooperació, el fet de tenir treballadors amb un nivell educatiu elevat i l'aplicació intensiva de les TIC han estat elements indispensables en aquest procés innovador. Finalment, gràcies a l'ús de les TIC i el seu impacte en la innovació, però també al canvi organitzatiu dins l'empresa, s'han millorat els registres de productivitat, amb la qual cosa s'afavoreix una major competitivitat en un context canviant i de forta pressió de l'entorn.

BACKGROUND: Despite the progress over recent decades in developing community mental health services internationally, many people still receive treatment and care in institutional settings. Those most likely to reside longest in these facilities have the most complex mental health problems and are at most risk of potential abuses of care and exploitation. This study aimed to develop an international, standardised toolkit to assess the quality of care in longer term hospital and community based mental health units, including the degree to which human rights, social inclusion and autonomy are promoted. METHOD: The domains of care included in the toolkit were identified from a systematic literature review, international expert Delphi exercise, and review of care standards in ten European countries. The draft toolkit comprised 154 questions for unit managers. Inter-rater reliability was tested in 202 units across ten countries at different stages of deinstitutionalisation and development of community mental health services. Exploratory factor analysis was used to corroborate the allocation of items to domains. Feedback from those using the toolkit was collected about its usefulness and ease of completion. RESULTS: The toolkit had excellent inter-rater reliability and few items with narrow spread of response. Unit managers found the content highly relevant and were able to complete it in around 90 minutes. Minimal refinement was required and the final version comprised 145 questions assessing seven domains of care. CONCLUSIONS: Triangulation of qualitative and quantitative evidence directed the development of a robust and comprehensive international quality assessment toolkit for units in highly variable socioeconomic and political contexts

Introduction: Testing for HIV tropism is recommended before prescribing a chemokine receptor blocker. To date, in most European countries HIV tropism is determined using a phenotypic test. Recently, new data have emerged supporting the use of a genotypic HIV V3-loop sequence analysis as the basis for tropism determination. The European guidelines group on clinical management of HIV-1 tropism testing was established to make recommendations to clinicians and virologists. Methods: We searched online databases for articles from Jan 2006 until March 2010 with the terms: tropism or CCR5-antagonist or CCR5 antagonist or maraviroc or vicriviroc. Additional articles and/or conference abstracts were identified by hand searching. This strategy identified 712 potential articles and 1240 abstracts. All were reviewed and finally 57 papers and 42 abstracts were included and used by the panel to reach a consensus statement. Results: The panel recommends HIV-tropism testing for the following indications: i) drug-naïve patients in whom toxicity or limited therapeutic options are foreseen; ii) patients experiencing therapy failure whenever a treatment change is considered. Both the phenotypic Enhanced Trofile assay (ESTA) and genotypic population sequencing of the V3-loop are recommended for use in clinical practice. Although the panel does not recommend one methodology over another it is anticipated that genotypic testing will be used more frequently because of its greater accessibility, lower cost and shorter turnaround time. The panel also provides guidance on technical aspects and interpretation issues. If using genotypic methods, triplicate PCR amplification and sequencing testing is advised using the G2P interpretation tool (clonal model) with an FPR of 10%. If the viral load is below the level of reliable amplification, proviral DNA can be used, and the panel recommends performing triplicate testing and use of an FPR of 10%. If genotypic DNA testing is not performed in triplicate the FPR should be increased to 20%. Conclusions: The European guidelines on clinical management of HIV-1 tropism testing provide an overview of current literature, evidence-based recommendations for the clinical use of tropism testing and expert guidance on unresolved issues and current developments. Current data support both the use of genotypic population sequencing and ESTA for co-receptor tropism determination. For practical reasons genotypic population sequencing is the preferred method in Europe.

Background: Numerous hypermethylated genes have been reported in breast cancer, and the silencing of these genes plays an important role in carcinogenesis, tumor progression and diagnosis. These hypermethylated promoters are very rarely found in normal breast. It has been suggested that aberrant hypermethylation may be useful as a biomarker, with implications for breast cancer etiology, diagnosis, and management. The relationship between primary neoplasm and metastasis remains largely unknown. There has been no comprehensive comparative study on the clinical usefulness of tumor-associated methylated DNA biomarkers in primary breast carcinoma and metastatic breast carcinoma. The objective of the present study was to investigate the association between clinical extension of breast cancer and methylation status of Estrogen Receptor1 (ESR1) and Stratifin (14-3-3-σ) gene promoters in disease-free and metastatic breast cancer patients. Methods: We studied two cohorts of patients: 77 patients treated for breast cancer with no signs of disease, and 34 patients with metastatic breast cancer. DNA was obtained from serum samples, and promoter methylation status was determined by using DNA bisulfite modification and quantitative methylation-specific PCR. Results: Serum levels of methylated gene promoter 14-3-3-σ significantly differed between Control and Metastatic Breast Cancer groups (P < 0.001), and between Disease-Free and Metastatic Breast Cancer groups (P < 0.001). The ratio of the 14-3-3-σ level before the first chemotherapy cycle to the level just before administration of the second chemotherapy cycle was defined as the Biomarker Response Ratio [BRR]. We calculated BRR values for the "continuous decline" and "rise-and-fall" groups. Subsequent ROC analysis showed a sensitivity of 75% (95% CI: 47.6 - 86.7) and a specificity of 66.7% (95% CI: 41.0 - 86.7) to discriminate between the groups for a cut-off level of BRR = 2.39. The area under the ROC curve (Z = 0.804 ± 0.074) indicates that this test is a good approach to post-treatment prognosis. Conclusions: The relationship of 14-3-3-σ with breast cancer metastasis and progression found in this study suggests a possible application of 14-3-3-σ as a biomarker to screen for metastasis and to follow up patients treated for metastatic breast cancer, monitoring their disease status and treatment response.

Background: We aim to investigate the possibility of using 18F-positron emission tomography/computer tomography (PET-CT) to predict the histopathologic response in locally advanced rectal cancer (LARC) treated with preoperative chemoradiation (CRT). Methods: The study included 50 patients with LARC treated with preoperative CRT. All patients were evaluated by PET-CT before and after CRT, and results were compared to histopathologic response quantified by tumour regression grade (patients with TRG 1-2 being defined as responders and patients with grade 3-5 as non-responders). Furthermore, the predictive value of metabolic imaging for pathologic complete response (ypCR) was investigated. Results: Responders and non-responders showed statistically significant differences according to Mandard's criteria for maximum standardized uptake value (SUVmax) before and after CRT with a specificity of 76,6% and a positive predictive value of 66,7%. Furthermore, SUVmax values after CRT were able to differentiate patients with ypCR with a sensitivity of 63% and a specificity of 74,4% (positive predictive value 41,2% and negative predictive value 87,9%); This rather low sensitivity and specificity determined that PET-CT was only able to distinguish 7 cases of ypCR from a total of 11 patients. Conclusions: We conclude that 18-F PET-CT performed five to seven weeks after the end of CRT can visualise functional tumour response in LARC. In contrast, metabolic imaging with 18-F PET-CT is not able to predict patients with ypCR accurately
