Factores asociados a la mortalidad en los pacientes con exacerbación de enfermedad pulmonar obstructiva crónica hospitalizados en servicios de medicina interna

Avaluació dels factors de risc que es relacionen amb la mortalitat en pacients amb exacerbació de la MPOC hospitalitzats en serveis de Medicina Interna en un estudi multicèntric transversal, valorant la possible associació de la mort hospitalitzats amb diferents variables: sociodemogràfiques, tractament abans i durant la hospitalització, característiques clíniques de la MPOC, comorbiditats prèvies, dades clíniques, resultats de laboratori i troballes electrocardiogràfics. Amb 398 pacients, 88,7% eren homes i amb una mitjana de 75 anys, va morir un 5,3%. Trobant associació entre el risc de morir durant l'hospitalització i el diagnòstic previ de pneumònia, malaltia coronària i ACV.

From the perspective of redistributing income fromrich to poor, equalizing intergovernmental grants are bound to have some perverse effects. For suchgrants, although transfering income from wealthy topoor on average, will inevitably result in some incometransfers from poor individuals who reside in wealthyjurisdictions to rich persons in generally poor areas.

Impact of the Spanish smoking law on exponsure to secondhand smoke in offices and hospitality venues: before-and-after study

BACKGROUND/OBJECTIVES: A smoking law was passed by the Spanish Parliament in December 2005 and was enforced by 1 January 2006. The law bans smoking in all indoor workplaces but only in some hospitality venues, because owners are allowed to establish a smoking zone (venues>100 m2) or to allow smoking without restrictions (venues<100 m2). The objective of the study is to assess the impact of the Spanish smoking law on exposure to secondhand smoke (SHS) in enclosed workplaces, including hospitality venues. MATERIALS AND METHODS: The study design is a before-and-after evaluation. We studied workplaces and hospitality venues from eight different regions of Spain. We took repeated samples of vapor-phase nicotine concentration in 398 premises, including private offices (162), public administration offices (90), university premises (43), bars and restaurants (79), and discotheques and pubs (24). RESULTS: In the follow-up period, SHS levels were markedly reduced in indoor offices. The median decrease in nicotine concentration ranged from 60.0% in public premises to 97.4% in private areas. Nicotine concentrations were also markedly reduced in bars and restaurants that became smoke-free (96.7%) and in the no-smoking zones of venues with separate spaces for smokers (88.9%). We found no significant changes in smoking zones or in premises allowing smoking, including discotheques and pubs. CONCLUSIONS: Overall, this study shows the positive impact of the law on reducing SHS in indoor workplaces. However, SHS was substantially reduced only in bars and restaurants that became smoke-free. Most hospitality workers continue to be exposed to very high levels of SHS. Therefore, a 100% smoke-free policy for all hospitality venues is required.

Ensayo de preferencia de individuos alados de Rhopalosiphum maidis (Fitch) (Homoptera: Aphididae) sobre siete gramíneas cultivadas

Se evaluó en laboratorio la preferencia de dos poblaciones leridanas de Rhopalosiphum maidis (Fitch) en la colonización de siete gramíneas cultivadas. Una de las poblaciones fue recogida sobre cañota (Sorghum halepense C. (L.) Pers.) y su cariotipo era 2n = 8. Los individuos de la otra población presentaban un cariotipo 2n = 10 y procedían de cebada. Las gramíneas testadas fueron: sorgo, maíz, trigo, trigo duro, cebada, triticale y avena. Los individuos alados de ambas poblaciones colonizaron los siete cereales aunque de distinta manera. El sorgo fue preferentemente colonizado por los pulgones con cariotipo 2n = 8 y el número de ninfas producidas en 48 horas fue mayor que en el resto de las gramíneas testadas. Los pulgones con cariotipo 2n = 10 mostraron preferencia por la cebada. Los alados de ambas poblaciones fueron incapaces de reproducirse sobre las plantas de maíz.

Populations of breeding birds in Byers Peninsula, Livingston Island, South Shetland Islands

Data about breeding populations of birds in the Antarctica are rare and fragmented. Thus, information about the status of the breeding populations of Antarctic birds is crucial given the current scenario of climate change, which is particularly acute in Antarctica. This paper presents new information about the populations of the Antarctic tern Sterna vittata, the kelp gull Larus dominicanus, the southern giant petrel Macronectes giganteus, the Antarctic skua Catharacta antarctica lonnbergi, the chinstrap penguin Pygoscelis antarctica and the gentoo penguin Pygoscelis papua on Byers Peninsula (Livingston Island, South Shetland Islands). We used line transects counts to estimate both densities and numbers of nests of the different species. We estimate that there are 398.96 birds km-2 of southern giant petrels (2793 individuals), 62.4 birds km-2 of Antarctic tern (3746 individuals) and 269.1 birds km-2 of kelp gull (1884 individuals). Furthermore, we found 15 nests of Antarctic skua in 25 km2, from which we can estimate that 6091 birds must breed on Byers Peninsula. We also censused two colonies of gentoo penguins (3000 and 1200 pairs) and 50 pairs of chinstrap. Compared to previous estimates, gentoo penguins seem to have increased whereas chinstrap penguin have decreased. Finally, the populations of Antarctic tern, southern giant petrel and kelp gull have stabilized or slightly increased.
