Prevalence of iodine inadequacy in Switzerland assessed by the estimated average requirement cut-point method in relation to the impact of iodized salt.

OBJECTIVE: To assess the iodine status of Swiss population groups and to evaluate the influence of iodized salt as a vector for iodine fortification. DESIGN: The relationship between 24 h urinary iodine and Na excretions was assessed in the general population after correcting for confounders. Single-day intakes were estimated assuming that 92 % of dietary iodine was excreted in 24 h urine. Usual intake distributions were derived for male and female population groups after adjustment for within-subject variability. The estimated average requirement (EAR) cut-point method was applied as guidance to assess the inadequacy of the iodine supply. SETTING: Public health strategies to reduce the dietary salt intake in the general population may affect its iodine supply. SUBJECTS: The study population (1481 volunteers, aged ≥15 years) was randomly selected from three different linguistic regions of Switzerland. RESULTS: The 24 h urine samples from 1420 participants were determined to be properly collected. Mean iodine intakes obtained for men (n 705) and women (n 715) were 179 (sd 68.1) µg/d and 138 (sd 57.8) µg/d, respectively. Urinary Na and Ca, and BMI were significantly and positively associated with higher iodine intake, as were men and non-smokers. Fifty-four per cent of the total iodine intake originated from iodized salt. The prevalence of inadequate iodine intake as estimated by the EAR cut-point method was 2 % for men and 14 % for women. CONCLUSIONS: The estimated prevalence of inadequate iodine intake was within the optimal target range of 2-3 % for men, but not for women.

Estudi de la contaminacio atmosferica de la plana del camp de Tarragona (Catalunya) prenent els liquens com a bioindicadors

Se evalua la contaminación atmosférica de la llanura litoral del Camp de Tarragona (Cataluña) tomando como bioindicadores los líquens epífitos del algarrobo (Ceratonia Siliqua). Se caracterizan ochenta y cinco estaciones según diversos parámetros: índice de pureza atmosférica (IPA), recubrimiento medio global (RMG) y nombres de especies. La combinación de los datos obtenidos permite dividir el área estudiada en seis zonas de isocontaminación. Por otra parte, se clasifican 15 especies de líquenes y el alga Pleurococcus en función de su resistencia a la contaminación atmosférica.

Espècies fitoparàsites de la Família Esferopsidàcies a Catalunya

L'anàlisi fitosanitària d'unes 40 especies de plantes precedents de diferents localitats de Catalunya, ens ha permès de detectar la presencia de mes de 40 especies de la Fam. Esferopsidàcies que pertanyen a 13 generes. Entre els patrons figuren algunas especies de fongs com Oidium ambrosiae, O. erysiphoides, Uromyces geranii, U. striatus i Tranzschelia pruni-spinosae, que a la vegada son parasitades per altres fongs d'aquesta familia. Cal precisar que si bë algunes d¿aquestes especies han estat citades per nosaltres (Fongs Imperfects paràsits de les plantes a Catalunya, Quaderns Agraris nº 1) algunes altres, com s'indica en la publicació abans esmentada, són noves per Catalunya.

Tobacco control policies in hospitals before and after the implementation of a national smoking ban in Catalonia, Spain

Background: Diverse projects and guidelines to assist hospitals towards the attainment of comprehensive smoke-free policies have been developed. In 2006, Spain government passed a new smoking ban that reinforce tobacco control policies and banned completely smoking in hospitals. This study assesses the progression of tobacco control policies in the Catalan Network of Smokefree Hospitals before and after a comprehensive national smoking ban. Methods: We used the Self-Audit Questionnaire of the European Network for Smoke-free Hospitals to score the compliance of 9 policy standards (global score = 102). We used two crosssectional surveys to evaluate tobacco control policies before (2005) and after the implementation of a national smoking ban (2007) in 32 hospitals of Catalonia, Spain. We compared the means of the overall score in 2005 and 2007 according to the type of hospital, the number of beds, the prevalence of tobacco consumption, and the number of years as a smoke-free hospital. Results: The mean of the implementation score of tobacco control policies was 52.4 (95% CI:45.4-59.5) in 2005 and 71.6 (95% CI: 67.0-76.2) in 2007 with an increase of 36.7% (p < 0.01). The hospitals with greater improvement were general hospitals (48% increase; p < 0.01), hospitals with > 300 beds (41.1% increase; p < 0.01), hospitals with employees' tobacco consumption prevalence 35-39% (72.2% increase; p < 0.05) and hospitals that had recently implemented smoke-free policies (74.2% increase; p < 0.01). Conclusion: The national smoking ban appears to increase tobacco control activities in hospitals combined with other non-bylaw initiatives such as the Smoke-free Hospital Network.

La maçoneria, escola de formació. La seva presència a la Catalunya del dinou.

És comunament acceptada l'opinió que la maçoneria va contribuir, durant els segles XVIII i XIX, al triomf i a la consolidació deis valors que hom ha convingut a anomenar moderns. La raó, la dignitat humana, la justícia i la llibertat van ser, entre d'altres, principis assumits pels maçons com a propis, i damunt els quals s'havia d'edificar el nou temple de la modernitat. Tampoc els projectes de filantropia, interpretada com un amor envers la humanitat i millora del gènere humà, no quedaven al marge de l'ideari maçònic. És lògic, doncs, que aquesta filosofia fos assumida per bona part d'una burgesia progressista desitjosa d'anorrear qualsevol vestigi possible d'obscurantisme, i donant suport, naturalment, a aquells moviments revolucionaris d'ascendència liberal que pul·lulaven tant arreu d'Europa com d'Amèrica. De fet, tot i el risc de caure en un cert reduccionisme, podem vincular l'acció de la maçoneria amb el triomf deis ideal s burgesos.

Salt stress change chlorophyll fluorescence in mango

This study evaluated the tolerance of mango cultivars 'Haden', 'Palmer', 'Tommy Atkins' and 'Uba' grafted on rootstock 'Imbú' to salt stress using chlorophyll fluorescence. Plants were grown in modified Hoagland solution containing 0, 15, 30, and 45 mmol L-1 NaCl. At 97 days the parameters of the chlorophyll fluorescence (F0, Fm, Fv, F0/Fm, Fv/Fm, Fv'/Fm', ΦPSII = [(Fm'-Fs)/(Fm')], D = (1- Fv'/Fm') and ETR = (ΦPSII×PPF×0,84×0,5) were determined. At 100 days, the leaf emission and leaf area, toxicity and leaf abscission indexes were determined. In all cultivars evaluated, in different degree, there were decreases in photochemical efficiency of photosystem II, enhanced concentrations from 15 mmol L-1 NaCl. The decreases in the potential quantum yield of photosystem II (Fv/Fm) were 27.9, 18.7, 20.5, and 27.4%, for cultivars 'Haden', 'Palmer', 'Tommy Atkins', and 'Uba', respectively, when grown in 45 mmol L-1 NaCl. It was found decreases in leaf emission and mean leaf area in all cultivars from 15 mmol L-1 NaCl. There were increases in leaf toxicity of 33.0, 67.5, 41.6 and 80.8% and in leaf abscission of 71.8, 29.2, 32.5, and 67.9% for the cultivars 'Haden', 'Palmer', 'Tommy Atkins', and 'Uba' respectively, when grown in 45 mmol L-1 NaCl. Leaf toxicity and leaf abscission were not observed in 15 mmol L-1 NaCl. The decrease in Fv/Fm ratio were accompanied by decreasing in leaf emission and increased leaf toxicity index, showing, therefore, the potential of chlorophyll fluorescence in the early detection of salt stress in mango tree.

El paper de Lluís Solé Sabarís en la "Geografia de Catalunya" (1958-1974)

Parlar de Lluís Solé Sabarís com a geògraf és una tasca que ultrapassa de molt les meves possibilitats, ja que no es tracta simplement d'escorcollar els aspectes mes geografics d'un geòleg. Ans al contrari, sense voler prejutjar la seva tasca immensa en el camp de la Geologia, cal dir tot seguit que Solé Sabarís és ell mateix un geògraf. Efectivament, des de les seves classes de Geografia a 1'Institut-escola «Giner de los Ríos» de la Generalitat a les seves activitats mes recents com a president de la Societat Catalana de Geografia, passant pel seu mestratge a tants de geografs al Consejo Superior de Investigaciones Científicas de Barcelona o als cursets de Pirineus, o per bona part de les seves obres i escrits, arreu hi podem trobar l'alenar de tot un geògraf de l'escola francesa. L'anàlisi de tota aquesta tasca ultrapassa de molt les meves possibilitats. Moltes coses són encara massa recents, i de testimonis més qualificats n'hi ha també molts d'altres.

Dendroecologia de Pinus sylvestris en Catalunya

En el presente trabajo se ha llevado a cabo un estudio de las limitaciones climaticas del crecimiento secundario de Pinus sylvestris L. en tres zonas de Catalunya. Para ello se han establecido 10 cronologias en otras tantas localidades, de las que 6 corresponden al Prepirineo, 2 al Montseny y 2 a Prades. La metodologia utilizada para poner de manifiesto las relaciones clima- crecimiento ha sido el análisis de regresión múltiple en componentes principales, obteniéndose asi las funciones respuesta. Los resultados confirmaron la hipotesis de que esta especie, incluso en la zona del Prepirineo, se ve influenciada por el estrés hídric0 durante la estación de crecimiento y aunque existe una respuesta similar en las tres zonas de estudio, también se producen diferencias. El efecto de inercia o el retardo con que las especies responden a 10s estímulos climaticos se ha puesto de manifiesto al presentar, alguno de 10s factores climaticos, coeficientes significativos en periodos anteriores a la estación actual de crecimiento. Los resultados son comentados desde la ecofisiologia de esta especie, comparándolos con 10s obtenidos por otros autores en el norte de su distribución geográfica. Finalmente se hace referencia a la estrategia adaptativa de P. sylvestris, considerada una especie pionera
