El treball que presentem forma part de la tasca duta a terme, a l'empara d'un projecte d'innovació docent de la Universitat de Lleida. Aquest projecte, parteix de la necessitat d'adaptar les directrius comunes reguladores de les pràctiques externes (pràcticum) a les particularitats dels estudis de Grau, i en concret dels estudis de les titulacions de l'Escola Politècnica Superior i de la Facultat de Dret i Economia Els nous estudis de grau entenen que la formació ha de basar-se en l'adquisició de competències, en la globalitat de les capacitats dels estudiants i en l'organització dels continguts de la formació des d'una lògica més productiva, menys acadèmica i més orientada a la solució de problemes. De manera que l'avaluació del pràcticum haurà d'incloure evidències que ho contemplin explícitament. És per això que, l'objectiu principal de l'estudi és l'elaboració d'una proposta d'avaluació del pràcticum basada en competències mitjançant el disseny d'una Matriu d'Avaluació

Es presenta una experiència de realització de treballs pràctics autogestionats per grups d'estudiants de Dret. El professorat planteja un marc general de treball que atribueix a l'alumnat un marge considerable d'elecció pel que fa al tema a treballar, el format del treball, el règim d'organització del treball en grup, el contingut del treball, i la seva presentació. Se n'analitzen els resultats, punts forts i punts febles, a partir d'una enquesta feta a l'alumnat sobre la valoració de l'autogestió

Abstract Background Non-steroidal antiinflammatory drugs (NSAIDs) are the most commonly prescribed agents for arthritic patients, although gastric effects limit their long-term use. Considering the reported gastric safety of hydrogen sulfide (H2S)-releasing NSAIDs, in addition to the anti-inflammatory effects of H2S administration to rats with synovitis, we decided to evaluate the effects of the H2S-releasing naproxen derivative ATB-346 in this animal model. Methods Male Wistar rats were anesthetized with inhalatory halothane and pre-treated with equimolar oral doses of either naproxen (0.3, 1, 3 or 10 mg/kg) or ATB-346 (0.48, 1.6, 4.8, or 16 mg/kg) 30 min before the i.art. injection of 7.5 mg of carrageenan (CGN) into the right knee joint cavity. Joint swelling and pain score were assessed after 1, 3 and 5 h, and tactile allodynia after 2 and 4 h. After the last measurement, the joint cavity lavages were performed for counting of the recruited leukocytes. The drugs (at the highest doses) were also tested for their gastric effects by evaluating macroscopical damage score and neutrophil recruitment (measured as myeloperoxidase – MPO activity) in the stomachs 5 h after administration of the drugs. In addition, the serum naproxen pharmacokinetic profiles of both compounds, administered at the highest equimolar doses, were obtained during the first 6 h after dosing. Results At the two highest tested doses, both naproxen and ATB-346 reduced edema and pain score (measured 3 and 5 h after CGN; P < 0.001). Tactile allodynia was similarly inhibited by ~45% 4 h after CGN by both naproxen (at 1, 3 and 10 mg/kg) and ATB-346 (at 1.6 and 4.8 mg/kg; P < 0.001), as well as leukocyte infiltration. Naproxen (but not ATB-346) induced significant gastric damage and, despite the increased gastric MPO activity by ~130% in the naproxen-, but not in the ATB-346-treated rats, this effect was of no statistical significance. Conclusion The presence of a H2S-releasing moiety in the ATB-346 structure does not impair the antiinflammatory activity of the parent compound in rats with CGN-induced synovitis. In addition, released H2S may account for the absence of deleterious gastric effects, thus making of ATB-346 a potentially useful therapeutic alternative to traditional naproxen for treatment of patients with arthritis.
