La reinserció social de les persones drogodependents a Catalunya és un àmbit relativament poc estudiat. L’estat actual dels recursos existents al territori no ha estat analitzat en cap ocasió. Per aquest motiu, en aquest treball es realitzarà un anàlisi de les associacions i entitats que conformen la xarxa de serveis socials per a aquest col·lectiu a Catalunya.Per a desenvolupar un anàlisi el màxim de complert i eficaç es tindran en compte 20 associacions que despleguen 7 tipus de serveis en tot el territori: Centres de dia, pisos de reinserció, tallers, empreses, activitats laborals, programes d’inserció laboral i programes esportius.Per a cada categoria de servei es buscarà els aspectes positius i els aspectes a millorar basant-se en l’evidència empírica, valoracions i criteris establerts per diferents institucions internacionals, entitats i organitzacions. També es recolliran les opinions personals de diferents professionals entrevistats sobre la valoració de l’estat actual de la xarxa i dels serveis que ells ofereixen.Un dels aspectes a ressaltar derivats de l’anàlisi de la xarxa és l’evident manca de recursos, així com també és fa patent la necessitat de redefinir el concepte de “reinserció social” per aconseguir eliminar barreres en l’accés als recursos destinats al col·lectiu.

Recently a fingering morphology, resembling the hydrodynamic Saffman-Taylor instability, was identified in the quasi-two-dimensional electrodeposition of copper. We present here measurements of the dispersion relation of the growing front. The instability is accompanied by gravity-driven convection rolls at the electrodes, which are examined using particle image velocimetry. While at the anode the theory presented by Chazalviel et al. [J. Electroanal. Chem. 407, 61 (1996)] describes the convection roll, the flow field at the cathode is more complicated because of the growing deposit. In particular, the analysis of the orientation of the velocity vectors reveals some lag of the development of the convection roll compared to the finger envelope.

Objective: To demonstrate successful in situ aortoiliac reconstruction of an infected infrarenal aneurysm using one single superficial femoral vein (SFV). Methods: In situ reconstruction using the right SFV sutured in end-to-end anastomosis with the aorta and distally with the right common iliac artery and in end-to-side anastomosis with the left common iliac artery. Results: The operating time was less than reported for aortic in situ reconstruction with bilateral SFV harvesting. The duplex scan 3 months postoperatively showed permeability of the bypass without any anastomotic stenosis or pseudoaneurysm. The right common femoral, popliteal, and greater saphenous veins were patent without thrombus, and the patient did not complain about peripheral edema. Conclusions: The use of only one instead of both the SFVs for aortobiiliac in situ reconstruction might be a way to reduce operating time and allow autogenous venous reconstruction even in patients with limited availability of venous material.

OBJECTIVE: The objective of this study was to analyse the long-term mortality and morbidity of a group of patients undergoing thrombolysis during the acute phase of myocardial infarction and to determine the factors influencing the prognosis. One hundred and seventy five patients (149 mean and 26 women, mean age: 54 years) were included in a randomized study, comparing the efficacy of 2 thrombolytic substances administered during the acute phase of myocardial infarction. A standard questionnaire was sent to the various attending physicians to follow-up of these 175 patients. RESULTS: The hospital mortality was 5% (9 patients) and 14 patients (9%) died after a mean follow-up of 4.3 +/- 2.1 years. The 5-year actuarial survival was 81%. Fourteen patients (8%) were lost to follow-up and 49 patients (32%) underwent surgical or percutaneous revascularization during follow-up. Revascularized patients had a significantly better survival than non-revascularized patients. The mean left ventricular ejection fraction of patients who died was lower (48% versus 71%) than that of survivors. Patients with an ejection fraction < 40% also had a significantly lower survival (p = 0.01). Patency of the vessel after thrombolysis was associated with a slightly better survival; this difference was not significant. The ejection fraction at 6 month was also significantly higher (60 +/- 10% versus 49 +/- 11%) for patients with a patent artery. Three risk factors for death or reinfarction were identified: age > 65 years at the time of infarction, disease in more than one coronary vessel and absence of angina pectoris before infarction. The probability of a coronary accident varied from 2 to 88% according to the number of risk factors present. At the time of follow-up, 60% of patients presented hypercholesterolaemia versus only 7% before infarction 73% of patients received anticoagulant or antiaggregant treatment and 81% of patients were asymptomatic. CONCLUSION: The mortality and the acute and long-term morbidity of myocardial infarction remain high, as only 34% of our patients did not develop any events during follow-up, despite serious medical management and follow-up. The ejection fraction has an important prognostic value. Patient management should take the abovementioned risk factors into account.

La relación entre el trabajo y la salud puede abordarse desde distintas perspectivas. El abordaje de los riesgos a los cuales los trabajadores están expuestos, en psicología, tiene su origen en lo que se conoce como riesgos emergentes, haciendo referencia a aquellos resultantes de la organización del trabajo. Estos se manifiestan a través de problemas como el absentismo, defectos de calidad, estrés, ansiedad, etc. y en ocasiones en trastornos músculo-esqueléticos, que somatiza el trabajador. Así pues para conseguir el bienestar del trabajador, es necesario tener en cuenta la percepción que éste tiene de las condiciones psicosociales de su trabajo. Partiendo del estudio de un puesto de trabajo, desde un punto de vista ergonómico y psicosocial, y teniendo en cuenta la sintomatología del trabajador, se pretende llegar a conclusiones que determinen y definan tareas que llevadas a la práctica resulten más saludables. Desde una perspectiva más amplia, que la mera evaluación de un puesto de trabajo, se pretende establecer relación entre el desarrollo de alteraciones músculo-esqueléticas y una serie de factores relacionados con las condiciones de trabajo. En conclusión, mediante este estudio, podemos afirmar que no sólo las exigencias ergonómicas correlacionan con trastornos músculo-esqueléticos, o los factores psicosociales con la percepción de estrés, los factores personales así como los laborales de carácter psicosocial y organizacional, pueden tener relación directa sobre la intensificación de la sintomatología por trastornos músculo-esqueléticos.

Our objective was to evaluate efficacy and patency of metallic stent placement for symptomatic Budd-Chiari syndrome (BCS) due to prothrombotic disorders. Eleven patients with proved BCS due to prothrombotic disorders were referred for endovascular treatment because of refractory ascites (n=9), abdominal pain (n=8), jaundice (n=6), and/or gastrointestinal bleeding (n=4). Stents were inserted for stenosed hepatic vein (n=7), inferior vena cava (n=2), or mesenterico-caval shunt (n=2). Clinical efficacy and stent patency was evaluated by clinical and Doppler follow-up. After a mean follow-up of 21 months, 6 patients had fully patent stents without reintervention (primary stent patency: 55%). Two patients with hepatic vein stenosis had stent thrombosis and died 4 months after procedure. Restenosis occurred in 3 cases (2 hepatic vein and 1 mesenterico-caval shunt stenosis) and were successfully treated by balloon angioplasty (n=2) and addition of new stents (n=1) leading to a 82% secondary stent patency. Of 9 patients with patent stent, 7 were asymptomatic (77%) at the end of the study. Stent placement is a safe and effective procedure to control of symptomatic BCS. Prothrombotic disorder does not seem to jeopardize patency in anticoagulated patients.

Objective: To present the feasibility of bilateral lung transplantation after previously performed pneumonectomy.Methods: A 32 years old women underwent right pneumonectomy for bronchiectasis-related destroyed lung. Eight months later, she developed a vascular post-pneumonectomy syndrome and underwent realigning of the mediastinum by an intrathoracic expander that was complicated by an adult respiratory distress syndrome of the left lung requiring mechanical ventilation, arterio-venous CO2 removal (Novalung) and finally bilateral lung transplantation. Via clamshell incision, the post-pneumonectomy cavity was dissected and the superior vena cava (SVC) and carina were exposed. The pulmonary vessel stumps were dissected intrapericardically after realization of a right-sided hemi-pericardectomy. Extracorporeal circulation was started after central cannulation of the aorta and the inferior vena cava. A right upper lobe sleeve resection of the donor lung was performed. The intermediate bronchus was then implanted in the dissected recipient carina after realization of a hilar release maneuver. The right pulmonary artery was clamped between SVC andthe ascending aorta followed by end -to-end anastomosis of the donor and recipient artery and left atrial cuffs, respectively. Satisfactory graft function allowed decanulation and standard transplantation of the left lung without extracorporeal circulation.Results: Bronchoscopy and trans-esophageal echocardiography demonstrated a patent airway and vascular anastomoses without stenosis. Follow-up revealed excellent gas exchanges, no airway complications and well-functioning grafts on both sides with right-sided ventilation and perfusion two months after transplantation of 37% and 22%, respectively.Conclusion: This is to our knowledge the first report of successful bilateral lung transplantation after previous pneumonectomy unrelated to transplantation.

In this paper I present an endogenous growth model where the engine of growth is in-house R&D performed by high-tech firms. I model knowledge (patent) licensing among high-tech firms. I show that if there is knowledge licensing, high-tech firms innovate more and economic growth is higher than in cases when there are knowledge spillovers or there is no exchange of knowledge among high-tech firms. However, in case when there is knowledge licensing the number of high-tech firms is lower than in cases when there are knowledge spillovers or there is no exchange of knowledge.

Citalopram, a new bicyclic antidepressant, is the most selective serotonin reuptake inhibitor. In a number of double-blind controlled studies, citalopram was compared to placebo and to known tricyclic antidepressants. These studies have shown their efficacy and good safety. The inefficacy of a psychotropic treatment in at least 20% of depressives has led a number of authors to propose original drug combinations and associations, like antidepressant/lithium (Li), antidepressant/sleep deprivation (agrypnia), antidepressant/ECT, or antidepressant/LT3. The aim of this investigation is to evaluate the clinical effectiveness and safety of a combined citalopram/lithium treatment in therapy-resistant patients, taking account of serotonergic functions, as tested by the fenfluramine/prolactin test, and of drug pharmacokinetics and pharmacogenetics of metabolism. DESIGN OF THE STUDY: A washout period of 3 days before initiating the treatment is included. After an open treatment phase of 28 days (D) with citalopram (20 mg D1-D3; 40 mg D4-D14; 40 or 60 mg D15-D28; concomitant medication allowed: chloral, chlorazepate), the nonresponding patients [less than 50% improvement in the total score on the 21 item-Hamilton Depression Rating Scale (HDRS)] are selected and treated with or without Li (randomized in double-blind conditions: citalopram/Li or citalopram/placebo) during the treatment (D29-D35). Thereafter, all patients included in the double-blind phase subsequently receive an open treatment with citalopram/Li for 7 days (D36-D42). The hypothesis of a relationship between serotoninergic functions in patients using the fenfluramine/prolactin test (D1) and the clinical response to citalopram (and Li) is assessed. Moreover, it is evaluated whether the pharmacogenetic status of the patients, as determined by the mephenytoin/dextromethorphan test (D0-D28), is related to the metabolism of fenfluramine and citalopram, and also to the clinical response. CLINICAL ASSESSMENT: Patients with a diagnosis of major depressive disorders according to DSM III are submitted to a clinical assessment of D1, D7, D14, D28, D35, D42: HDRS, CGI (clinical global impression), VAS (visual analog scales for self-rating of depression), HDRS (Hamilton depression rating scale, 21 items), UKU (side effects scale), and to clinical laboratory examens, as well as ECG, control of weight, pulse, blood pressure at D1, D28, D35. Fenfluramine/prolactin test: A butterfly needle is inserted in a forearm vein at 7 h 45 and is kept patent with liquemine. Samples for plasma prolactin, and d- and l-fenfluramine determinations are drawn at 8 h 15 (base line). Patients are given 60 mg fenfluramine (as a racemate) at 8 h 30. Kinetic points are determined at 9 h 30, 10 h 30, 11 h 30, 12 h 30, 13 h 30. Plasma levels of d- and l-fenfluramine are determined by gas chromatography and prolactin by IRNA. Mephenytoin/dextromethorphan test: Patients empty their bladders before the test; they are then given 25 mg dextropethorphan and 100 mg mephenytoin (as a racemate) at 8 h 00. They collect all urines during the following 8 hours. The metabolic ratio is determined by gas chromatography (metabolic ratio dextromethorphan/dextrorphan greater than 0.3 = PM (poor metabolizer); mephenytoin/4-OH-mephenytoin greater than 5.6, or mephenytoin S/R greater than 0.8 = PM). Citalopram plasma levels: Plasma levels of citalopram, desmethylcitalopram and didesmethylcitalopram are determined by gas chromatography--mass spectrometry. RESULTS OF THE PILOT STUDY. The investigation has been preceded by a pilot study including 14 patients, using the abovementioned protocol, except that all nonresponders were medicated with citalopram/Li on D28 to D42. The mean total score (n = 14) on the 21 item Hamilton scale was significantly reduced after the treatment, ie from 26.93 +/- 5.80 on D1 to 8.57 +/- 6.90 on D35 (p less than 0.001). A similar patCitalopram, a new bicyclic antidepressant, is the most selective serotonin reu

A pesar de los notables avances en el estado del bienestar en nuestra sociedad muchas personas se sienten enfermas y trastornadas ante los vaivenes de la vida. El infortunio cotidiano tiene hoy día rango de enfermedad, muchas veces de enfermedad mental. De ahí, el notable aumento de las consultas en los diferentes dispositivos sanitarios de todo tipo. El consumo, la tecno-ciencia y el individualismo, los tres sistemas a través de los cuales tratamos de alcanzar la felicidad en la actualidad, influyen en la forma en la que experimentamos las adversidades de la vida. A su vez, los medios de comunicación, la industria farmacéutica, los profesionales y los pacientes, son los agentes implicados en lo que se ha dado en llamar la medicalización de la existencia. La conclusión es que las personas experimentan como enfermedades las contradicciones propias del sistema social.

En el joc hi conflueixen i s’entrellacen múltiples capacitats psicològiques de gran importància en el desenvolupament infantil i juvenil. L’objectiu d’aquest article ha estat analitzar el substrat psicològic de la conducta lúdica en la seva gènesi i posterior evolució. Hem parat especial atenció en l’aparició de la funció semiòtica, en els processos cognitius que hi estan implicats i en el paper decisiu que hi juga la comunicació. Finalment, reflexionem sobre una de les manifestacions més genuïnes del comportament humà, la recursivitat, la qual s’assoleix a través del llenguatge i el joc, se serveix d’aquests elements i, al mateix temps, en propulsa el desenvolupament.

Una de les principals preocupacions de l’ésser humà és la de desenvolupar capacitats que li permetin manejar la realitat, tant externa com interna. El joc, precisament, obre la possibilitat de crear un espai intermedi entre el que hi ha a fora (la realitat externa) i el que hi ha a dins (les necessitats personals, els desitjos, els sentiments). A l’infant, el joc que té lloc en aquest espai intermedi li permet d’anar rebent i incorporant aspectes del seu entorn més immediat (pares, família, escola) mitjançant el procés d’identificació i fer-ho, no d’una manera passiva, sinó com una incorporació activa, en la qual ell també és protagonista. Un espai intermedi que, en la vida adulta, permet de jugar mentalment amb les idees, amb experiències i sensacions, construint la base de la creativitat com a activitat cultural, científica o artística. En definitiva, doncs, el valor intrapsíquic del joc en l’ésser humà permet, des del punt de vista psicoanalític, la introjecció, la simbolització i la relació.
