A les Valls d’Àneu la producció ramadera de boví ecològic és molt important, ja que, actualment, el 22% de les explotacions són ecològiques i es preveu que aquest percentatge augmenti fins al 50% en els propers dos anys. Malgrat això, la motivació principal per a convertir les explotacions convencionals en ecològiques és el factor econòmic, no la consciència ambiental. En l’anàlisi del cicle productiu carni del boví ecològic procedent de les Valls d’Àneu s’ha observat que no hi ha diferències substancials entre la producció ecològica i la convencional. Tot i així, el producte carni de boví ecològic no té gran sortida al mercat, ja que aquest és incipient i, a més, el preu del producte ecològic és molt més elevat que el del convencional. Un aspecte crític de la producció ramadera ecològica és que la seva normativa no considera els impactes ambientals que genera, com són els derivats del transport, la generació de residus d’envasos, etc. En aquest estudi es presenta una aproximació quantitativa dels impactes generats en el cicle productiu carni de boví ecològic de les Valls d’Àneu.

Els arbres monumentals formen part del patrimoni natural, cultural i històric d’un país i com a tals són mereixedors de protecció. La Generalitat de Catalunya, sensible a aquest fet, ha regulat diferents figures de protecció per arbres que destaquen per algun motiu. Es tracta dels arbres monumentals, arbres d’interès comarcal i arbres d’interès local. Dels 194 arbres identificats i catalogats com a monumentals a Catalunya només 3 es troben a la comarca del Pallars Sobirà, en front dels, per exemple, 29 arbres catalogats a Osona. No hi ha cap arbre inventariat a la Vall d’Àneu, malgrat que és aquí on es troben la majoria de boscos vells amb exemplars de coníferes de grans dimensions. Cal destacar també que al Parc Natural de l’Alt Pirineu no hi trobem cap arbre catalogat com d’interès comarcal o d’interès local. Per aquest motiu s’ha cregut convenient aprofundir en l’estudi dels arbres monumentals, inventariant-ne els exemplars més destacats de la Vall d’Àneu i proposant-ne una categoria de protecció segons les seves característiques.

AIMS: To determine whether parental factors earlier in life (parenting, single parent family, parental substance use problem) are associated with patterns of alcohol consumption among young men in Switzerland. METHODS: This analysis of a population based sample from the Cohort Study on Substance Use Risk Factors (C-SURF) included 5,990 young men (mean age 19.51 years), all attending a mandatory recruitment process for the army. These conscripts reported on parental monitoring and rule-setting, parental behaviour and family structure. The alcohol use pattern was assessed through abstention, risky single occasion drinking (RSOD), volume drinking and dependence. Furthermore, the impact of age, family socio-economic status, educational level of the parents, language region and civil status was analysed. RESULTS: A parental substance use problem was positively associated with volume drinking and alcohol dependence in young Swiss men. Active parenting corresponded negatively with RSOD, volume drinking and alcohol dependence. Single parent family was not associated with a different alcohol consumption pattern compared to standard family. CONCLUSION: Parental influences earlier in life such as active parenting (monitoring, rule-setting and knowing the whereabouts) and perceived parental substance use problem are associated with alcohol drinking behaviour in young male adults. Therefore, health professionals should stress the importance of active parenting and parental substance use prevention in alcohol prevention strategies.

Her2/neu is a tyrosine kinase receptor which stimulates cell growth. The receptor is overexpressed in about 20% of breast cancers. Her2/neu expression is an indicator of poor prognosis but also the target of the treatment of breast cancer using humanised anti-Her2/ neu antibodies. Only cancers overexpressing the protein will respond to this therapy, but which has significant (cardiac) side effects and is expensive. It is therefore important to test for the overexpression of the protein on breast cancer cells. This paper discusses how this can be done and ongoing research into new therapeutic options targeting the involved signaling pathways.

Objective: To assess the safety/tolerability of the combination lapatinib (L) and docetaxel (D) in patients with Her 2/neu overexpressing breast cancer (BC). This study is important as it will define how to deliver lapatinib with taxotere, a highly active drug in breast cancer. Patients and Methods: Female patients (pts) with locally advanced, inflammatory or large operable BC were treated with escalating doses of L from 1000 to 1250 mg/day, in combination with D given IV every 21 days at doses ranging from 75 to 100 mg/m2 for 4 cycles. At least 3 pts were treated at each dose level. The definition of dose limiting toxicity (DLT) is based on the toxicity assessed at cycle 1 as follows: any grade 3−4 non hematological toxicity, ANC < 0.5 G/L lasting for 7 days or more, febrile neutropenia or thrombocytopenia <25 G/L. GCSF was not permitted as primary prophylaxis. Core biopsies were mandatory at baseline and after cycle 4. Pharmcokinetic (PK) samples were collected on day 1 of cycles 1 and 2. Results: To date, 18 pts with a median age of 53 years (range 36−65) have been enrolled at 5 Dose Levels (DLs). The toxicity profile for 18 patients (68 documented cycles) is summarized below. At DL5 (1000/100), 2 pts had DLTs (neutropenia grade 4 _7 days and febrile neutropenia), and 3 additional pts were enrolled with primary prophylactic G-CSF. As expected, the safety profile improved and the dose escalation will continue with prophylactic G-CSF to investigate DL6 (1250/100). These findings are consistent with published Phase I data for this combination [1]. N= 18 patients n (%) Grade 1 Grade 2 Grade 3 Grade 4 neutropenia 1 (6) 3 (17) 13 (72) febrile neutropenia 2 (11) fatigue 8 (44) 7 (39) diarrhoea 9 (50) 3 (17) pain: joint/muscle/other 5 (28)/4 (22)/3 (17) 4 (22)/4 (22)/3 (17) 0/0/1 (6) constipation 2 (11) 3 (17) 1 (6) elevated transaminases SGPT/SGOT 7 (39)/5 (28) Conclusions: The main toxicity of the L + D combination is haematological and was reached at DL5 (1000/100), without primary GCSF. An additional DL6 with primary prophylactic GCSF is being investigated (1250/100). PK data will be presented at the meeting plus the recommended dose for phase II studies.

OBJECTIVES: To determine the prevalence of Her-2/Neu-cerbb-2 in the gastric mucosa of patients with gastric adenocarcinoma in a brazilian patient group. METHODS: The immunohistochemical expression of Her-2/Neu was studied in 37 formalin-fixed paraffin-embedded tissue sections. RESULTS: The immunohistochemical reaction produced by the anti-HER-2/Neu antibody was positive in two cases (5.4%). CONCLUSION: The low prevalence of Her-2/Neu observed in these southern brazilian cases is probably due to the great number of poorly differentiated cancers in this serie.
