Gymnasieskola 2007 - Endast en vision?

Syftet med detta examensarbete var att ta reda på vilka tankar som finns angående helhetsperspektivet i den stundande gymnasiereformen Gymnasieskola 2007 (GY-07). För att få reda på detta intervjuades två rektorer och åtta lärare som fick ge sin syn på den kommande reformen. De tillhörde två olika program, ett studieförberedande respektive ett yrkesförberedande och dessa program kontrasteras mot varandra. Resultatet visar att alla informanter har en positiv inställning till reformen men att det yrkesförberedande programmet är mer positivt inställda än det studieförberedande programmet som hyser mindre tillförsikt till implementeringen av reformen.

High-Risk Merkel Cell Carcinoma of the Skin Treated With Synchronous Carboplatin/Etoposide and Radiation: A Trans-Tasman Radiation Oncology Group Study-TROG 96:07

Purpose: The effectiveness of synchronous carboplatin, etoposide, and radiation therapy was prospectively assessed in a group of patients with high-risk Merkel cell carcinoma (MCC) of the skin. Patients and Methods: Patients were eligible if they had disease localized to the primary site and nodes, and were required to have at least one of the following high risk features: recurrence after initial therapy, involved nodes, primary tumor size greater than 1 cm, gross residual disease after surgery, or occult primary with nodes. Radiation was delivered to the primary site and nodes to a dose of 50 Gy in 25 fractions over 5 weeks and synchronous carboplatin (area under the curve, 4.5) and intravenous etoposide 80 mg/m(2) days 1 to 3 was given in weeks 1, 4, 7, and 10. The median age of the group was 67 (range, 43-86) years, and there were 39 males and 14 females. Involved nodes (stage II) were present in 33 cases (62%). The sites involved were head and neck (22 patients), occult primary (13 patients), upper limb (eight patients), lower limb (eight patients), and trunk (two patients). Results: Fifty-three patients were entered between 1996 and 2001. The median potential follow-up was 48 months. There were no treatment related deaths. The 3-year overall survival, locoregional control, and distant control were 76%, 75%, and 76%, respectively. Tumor site and the presence of nodes were factors that were predictive for local control and survival. Multivariate analysis indicated that the major factor influencing survival was the presence of nodes; however, this was not a significant factor in locoregional control. Conclusion: High levels of locoregional control and survival have been achieved with the addition of chemotherapy to radiation treatment for high-risk MCC of the skin. The role of chemoradiotherapy for high-risk MCC warrants further investigation. (C) 2003 by American Society of Clinical Oncology.

Ultrasound evaluation of polymer gel dosimeters

A new method for the evaluation of radiotherapy 3D polymer gel dosimeters has been developed using ultrasound to assess the significant structural changes that occur following irradiation of the dosimeters. The ultrasonic parameters of acoustic speed of propagation, attenuation and transmitted signal intensity were measured as a function of absorbed radiation dose. The dose sensitivities for each parameter were determined as 1.8 x 10(-4) s m(-1) Gy(-1), 3.9 dB m(-1) Gy(-1) and 3.2 V-1 Gy(-1) respectively. All parameters displayed a strong variation with absorbed dose that continued beyond absorbed doses of 15 Gy. The ultrasonic measurements demonstrated a significantly larger dynamic range in dose response curves than that achieved with previously published magnetic resonance imaging (MRI) dose response data. It is concluded that ultrasound shows great potential as a technique for the evaluation of polymer gel dosimeters.

Braquiterapia intracoronariana. Tratamento da reestenose intra-stent com o sistema Beta-Cath: experiência inicial na América Latina

OBJETIVO: Avaliar a segurança e eficácia da braquiterapia intracoronariana usando o sistema Beta-CathTM na prevenção da recorrência de restenose intra-stent (RIS), por meio da análise dos resultados clínicos, angiográficos e pelo ultra-som intracoronariano (USIC). MÉTODO: Foram submetidos à angioplastia com cateter-balão, seguida de beta-radiação intracoronariana com o sistema Beta-CathTM (90Sr/Y) 30 pacientes com RIS em artérias coronárias nativas e, posteriormente, avaliados. RESULTADOS: Incluíram-se lesões reestenóticas complexas (77% do tipo difuso-proliferativo) com extensão elevada (18,66±4,15 mm). O sucesso da braquiterapia foi de 100%. A dose média utilizada foi de 20,7±2,3 Gy, liberada em um período médio de 3,8±2,1 min. No seguimento tardio, o diâmetro luminal mínimo (DLM) intra-stent diminuiu discretamente (1,98±0,30mm para 1,84±0,39 aos 6 meses, p=0,13), com uma perda tardia de 0,14±0,18 mm. O DLM intra-segmentar foi significativamente menor do que o intra-stent (1,55±0,40mm vs.1,84±0,39mm, p=0,008), associando-se à perda tardia (0,40±0,29mm vs. 0,14±0,18mm; p=0,0001). No USIC, observou-se discreto incremento do tecido neointimal em 6,8±14,3 mm³ aos 6 meses (p=0,19) e a percentagem de obstrução volumétrica aumentou em 4,7±7,5%. A reestenose binária e a revascularização do vaso-alvo recorreram em 17% dos casos; houve 1 caso (3%) de oclusão tardia, associada a infarto do miocárdio. A sobrevida livre de eventos foi de 80%. CONCLUSÃO: O manejo da reestenose intra-stent com a beta-radiação intracoronariana mostrou-se procedimento seguro e eficaz, com alta taxa de sucesso imediato, representando uma opção terapêutica para a inibição da hiperplasia neointimal.

Neoadjuvant chemoradiotherapy with or without panitumumab in patients with wild-type KRAS, locally advanced rectal cancer (LARC): a randomized, multicenter, phase II trial SAKK 41/07.

BACKGROUND: We conducted a randomized, phase II, multicenter study to evaluate the anti-epidermal growth factor receptor (EGFR) mAb panitumumab (P) in combination with chemoradiotherapy (CRT) with standard-dose capecitabine as neoadjuvant treatment for wild-type KRAS locally advanced rectal cancer (LARC). PATIENTS AND METHODS: Patients with wild-type KRAS, T3-4 and/or N+ LARC were randomly assigned to receive CRT with or without P (6 mg/kg). The primary end-point was pathological near-complete or complete tumor response (pNC/CR), defined as grade 3 (pNCR) or 4 (pCR) histological regression by Dworak classification (DC). RESULTS: Forty of 68 patients were randomly assigned to P + CRT and 28 to CRT. pNC/CR was achieved in 21 patients (53%) treated with P + CRT [95% confidence interval (CI) 36%-69%] versus 9 patients (32%) treated with CRT alone (95% CI: 16%-52%). pCR was achieved in 4 (10%) and 5 (18%) patients, and pNCR in 17 (43%) and 4 (14%) patients. In immunohistochemical analysis, most DC 3 cells were not apoptotic. The most common grade ≥3 toxic effects in the P + CRT/CRT arm were diarrhea (10%/6%) and anastomotic leakage (15%/4%). CONCLUSIONS: The addition of panitumumab to neoadjuvant CRT in patients with KRAS wild-type LARC resulted in a high pNC/CR rate, mostly grade 3 DC. The results of both treatment arms exceeded prespecified thresholds. The addition of panitumumab increased toxicity.

Fecundity Changes Induced by Low-Doses of Gamma Radiation on Biomphalaria straminea (Dunker, 1848)

A population of 420 snails Biomphalaria straminea, an intermediate host of Schistosoma mansoni, received gamma-rays obtained from a 60Co source in low-doses (0/2,5/5/7,5/10/15/20 and 25 Gy); half population was kept in colonies (allowing cross fertilization) and the other half was mantained in sexual isolation (allowing self fertilization). Results showed that 15 Gy stimulates the fertility of both groups but the colonies were more sensitive and at this dose its fertility overpasses the control group dose. The possible hormonal role played in the observed phenomena is under investigation

First-line temozolomide combined with bevacizumab in metastatic melanoma: a multicentre phase II trial (SAKK 50/07).

BACKGROUND: Oral temozolomide has shown similar efficacy to dacarbazine in phase III trials with median progression-free survival (PFS) of 2.1 months. Bevacizumab has an inhibitory effect on the proliferation of melanoma and sprouting endothelial cells. We evaluated the addition of bevacizumab to temozolomide to improve efficacy in stage IV melanoma. PATIENTS AND METHODS: Previously untreated metastatic melanoma patients with Eastern Cooperative Oncology Group performance status of two or more were treated with temozolomide 150 mg/m(2) days 1-7 orally and bevacizumab 10 mg/kg body weight i.v. day 1 every 2 weeks until disease progression or unacceptable toxicity. The primary end point was disease stabilisation rate [complete response (CR), partial response (PR) or stable disease (SD)] at week 12 (DSR12); secondary end points were best overall response, PFS, overall survival (OS) and adverse events. RESULTS: Sixty-two patients (median age 59 years) enrolled at nine Swiss centres. DSR12 was 52% (PR: 10 patients and SD: 22 patients). Confirmed overall response rate was 16.1% (CR: 1 patient and PR: 9 patients). Median PFS and OS were 4.2 and 9.6 months. OS (12.0 versus 9.2 months; P = 0.014) was higher in BRAF V600E wild-type patients. CONCLUSIONS: The primary end point was surpassed showing promising activity of this bevacizumab/temozolomide combination with a favourable toxicity profile. Response and OS were significantly higher in BRAF wild-type patients.

Seguiment de l'evolució de la recuperació del bosc de ribera en la zona afectada per l'incendi del riu Canaletes del 20/07/2009. Proposta de campanya de voluntariat ambiental en rius per la custòdia i recuperació fluvial

El riu Canaletes va resultar afectat per l’ incendi que es va produir a Horta de Sant Joan el juliol de l’any 2009. El foc va malmetre bona part de la flora i fauna de la zona, però un dels ecosistemes que en va sortir més perjudicat va ser el del bosc de ribera, ecosistema molt fràgil en front de pertorbacions d’aquest tipus, ja que la seva capacitat de regeneració no és tant senzilla ni ràpida com en altres ecosistemes mediterranis com podrien ser els boscos de pi blanc. No obstant, si que existeixen algunes espècies de ribera que presenten una ràpida resposta als incendis com és el cas dels salzes o alguns pollancres o àlbers, que en aquest cas, poc temps després del foc ja presentaven rebrots, segons observacions realitzades al camp. Per comprovar l’evolució de la recuperació del bosc de ribera en la zona afectada per l’incendi, es van realitzar diverses sortides de camp. D’aquestes observacions, es va poder deduir que actualment el bosc de ribera de la zona estudiada, evoluciona segons les previsions realitzades en estudis immediatament posteriors al foc, de manera que hi estan proliferant de manera ràpida bardisses amb esbarzer, gavarrera, roldor i sanguinyol, en aquells llocs que abans de l’incendi eren ocupats per arbres caducifolis.
