Integrated treatment of first episode psychosis with online training (e-learning): study protocol for a randomised controlled trial

Background: The integrated treatment of first episode psychosis has been shown to improve functionality and negative symptoms in previous studies. In this paper, we describe a study of integrated treatment (individual psychoeducation complementary to pharmacotherapy) versus treatment as usual, comparing results at baseline with those at 6-month re-assessment (at the end of the study) for these patients, and online training of professionals to provide this complementary treatment, with the following objectives: 1) to compare the efficacy of individual psychoeducation as add-on treatment versus treatment as usual in improving psychotic and mood symptoms; 2) to compare adherence to medication, functioning, insight, social response, quality of life, and brain-derived neurotrophic factor, between both groups; and 3) to analyse the efficacy of online training of psychotherapists. Methods/design: This is a single-blind randomised clinical trial including patients with first episode psychosis from hospitals across Spain, randomly assigned to either a control group with pharmacotherapy and regular sessions with their psychiatrist (treatment as usual) or an intervention group with integrated care including treatment as usual plus a psychoeducational intervention (14 sessions). Training for professionals involved at each participating centre was provided by the coordinating centre (University Hospital of Alava) through video conferences. Patients are evaluated with an extensive battery of tests assessing clinical and sociodemographic characteristics (Positive and Negative Syndrome Scale, State-Trait Anxiety Inventory, Liebowitz Social Anxiety Scale, Hamilton Rating Scale for Depression, Scale to Assess Unawareness of Mental Disorders, Strauss and Carpenter Prognostic Scale, Global Assessment of Functioning Scale, Morisky Green Adherence Scale, Functioning Assessment Short Test, World Health Organization Quality of Life instrument WHOQOL-BREF (an abbreviated version of the WHOQOL-100), and EuroQoL questionnaire), and brain-derived neurotrophic factor levels are measured in peripheral blood at baseline and at 6 months. The statistical analysis, including bivariate analysis, linear and logistic regression models, will be performed using SPSS. Discussion: This is an innovative study that includes the assessment of an integrated intervention for patients with first episode psychosis provided by professionals who are trained online, potentially making it possible to offer the intervention to more patients.

Identification of the main allergen sensitizers in an Iran asthmatic population by molecular diagnosis

Background: There has been a significant growth in the prevalence of allergy, mainly associated to IgE-mediated disorders such as asthma and rhinitis. The identification of atopy in asthmatic patients through the measurement of specific IgE can help to identify risk factors that cause asthmatic symptoms in patients. The development and use of individualized allergen-based tests by the Component Resolved Diagnosis has been a crucial advance in the accurate diagnosis and control of allergic patients. The objective of this work was to assess the usefulness of molecular diagnosis to identify environmental allergens as possible factors influencing the development and manifestation of asthma in a group of asthmatic patients from Iran. Methods: Studied population: 202 adult asthmatic patients treated at the Loghman Hakim Hospital and Pasteur Institute of Teheran (Iran) from 2011 to 2012. Specific IgE determined by the ImmunoCAP system were used to both evaluate the patients' atopic condition and the molecules involved in the allergic sensitization. SDS-PAGE IgE-immunoblotting associated with mass spectrometry was carried out to study the cockroach IgE-binding sensitizing proteins. Results: Forty-five percent of all patients could be considered atopic individuals. Eighty-two percent of atopic patients were sensitized to pollen allergens. The Salsola kali (Sal k 1) and the Phleum pratense (rPhl p 1 and/or rPhl p 5) major allergens were the most common sensitizers among pollens (71% and 18%, respectively). Thirty-five percent of the atopic population was sensitized to cockroach. Four different allergens, including a previously unknown alpha-amylase, were identified in the cockroach extract. No significant associations could be demonstrated between the severity of asthma and the specific IgE levels in the atopic population. Statistical analysis identified the Sal k 1 as the main protein allergen influencing the development and expression of asthma in the studied population. Conclusions: Pollen and cockroach were the most relevant allergen sources in the asthmatic population. The Salsola kali major allergen was the main cause for sensitization in the atopic patients suffering asthma. Using the Component Resolved Diagnosis, it was possible to identify a new Blattella germanica cockroach allergen (Blattella alpha amylase 53 kDa) that could sensitize a relevant percentage of this population.

Inplante kirurgiko erradiopakoen bideragarritasuna: plla/bario sulfato sistemaren ``in vitro´´ degradazioa.

[EU]Polimero biobateragarri eta biodegradagarrien erabilera medikuntza arloan aurrerapauso handia suposatu du. Inplanteen arloan (torlojuak, iltzeak, plakak, eta abar…) eta ehun ingeniaritzan garrantzia handia dute. Hala ere, polimero hauen inplanteek desabantaila nabaria aurkezten dute ohiko material metalikoekin alderatuz: erradiopazitate eza. Ikerketa lan honetan karga erradiopako baten adizioak polimero biobateragarri eta biodegradagarri baten giza gorputzaren baldintzetan (pH=7,2 eta 37ºC) burututako in vitro degradazioan duen eragina aztertu da, %70 poli(L-laktida) (PLLA) eta %30 bario sulfato (BaSO4) sistemaren degradazioa, hain zuzen ere. Aztertutako karga erradiopakoak PLLAren degradazioan eragin handirik ez duela ondorioztatu da, beraz, sistema bideragarria dela.

Optimización del proceso de producción del tubo vástago de un amortiguador Mcpherson: Caracterización del proceso de producción, metalográfica y propiedades mecánicas.

[ES]En este proyecto se va analizar metalúrgicamente todo el proceso de un tubo vástago para amortiguadores. El tubo a analizar es un tubo fabricado en Hijos de Juan Garay SA (HJG). Para analizar cada fase de fabricación del tubo, se cortan probetas en cada fase y se mandan a analizar a IK4-Azterlan. Con ello se obtiene la caracterización metalográfica y mecánica en cada momento, por lo tanto, analizando como conjunto todo los análisis de cada etapa de fabricación se podrá observar los cambios producidos en el tubo y obtener conclusiones para mejor sus proceso de producción.

Inplante erabilerako polimero erradio-opakoen lorpena eta ezaugarritzea

[EU]Biomedikuntzan gero eta material polimeriko gehiago aplikatzen dira. Metalezko inplanteekin alderatuz, ekoizterako orduan azkarragoak eta merkeagoak baitira beste hainbat ezaugarriren artean. Baina onurak ekartzearekin batera, erradio-opakotasun eza ere badakar. Eta ezaugarri hau gabe, inplantearen jarraipena behin giza gorputzean ezarrita dagoenean ezinezkoa da, X izpiekin ezin baita ikusi. Beraz, arazo horri aurre egiteko, proiektu honetan matrize polimerikoari kargak gehitzea proposatzen da. Lortutako material konposatuak, polimeroak soilik dituen ezaugarriak berdintzea edo hobetzea espero da. Hau da, erradio-opakotasuna lortzeaz gain, propietate mekanikoak behintzat mantentzea espero da. Giza gorputzean aplikatzen diren inplanteetarako erabiliko den material konposatu bat lortzea duenez helburu proiektu honek, matrizea polimero biobataragarria eta biodegradagarria izango da. Biodegradagarria izanik, inplantea kanporatzeko bigarren ebakuntza bat ekiditen da. Zehazki, poli(D-laktida) (PDLA) polimeroa matrize moduan eta karga moduan bismuto oxidoa (Bi2O3) erabiliko dira, medikuntza arloko inplanteetan erabili izan ohi dira eta.

Aerosorgailu palen aplikazioetarako pvc espumaren degradazio termiko eta propietate mekanikoen karakterizazioa

[EU]Energia berriztagarria iturri naturaletatik sortzen den energia mota da. Energia lortzeko erabiltzen diren baliabide naturalak asko dira, eguzki-energia, haizea, ura… Energia berriztagarrien artean, eolikoa da zabalkunde handien lortu duena; batez ere ingurumen-inpaktu urriagatik eta bere kostuak gero eta txikiagoak izateagatik. Honen ondorioz, energia garbi, lehiakor eta ekonomikoki bideragarria da gaur egun. Hala ere, aerosorgailu hauen ekoizpen prozesuak desabantaila nabaria aurkezten du palen ontze prozesuan. Tenperatura igoeraren ondorioz material konkretu baten degradazioa dela eta. Ikerketa lan honetan, aerosorgailu palen karakterizazioa egingo da eta ontze prozesuan, “polikloruro de binilo” (PVC)-ak jasaten duen degradazioaren azterketa.
