Tree line shifts in the Swiss Alps: Climate change or land abandonment?

Questions: Did the forest area in the Swiss Alps increase between 1985 and 1997? Does the forest expansion near the tree line represent an invasion into abandoned grasslands (ingrowth) or a true upward shift of the local tree line? What land cover / land use classes did primarily regenerate to forest, and what forest structural types did primarily regenerate? And, what are possible drivers of forest regeneration in the tree line ecotone, climate and/or land use change? Location: Swiss Alps. Methods: Forest expansion was quantified using data from the repeated Swiss land use statistics GEOSTAT. A moving window algorithm was developed to distinguish between forest ingrowth and upward shift. To test a possible climate change influence, the resulting upward shifts were compared to a potential regional tree line. Results: A significant increase of forest cover was found between 1650 to and 2450 m. Above 1650 m, 10% of the new forest areas were identified as true upward shifts whereas 90% represented ingrowth, and we identified both land use and climate change as likely drivers. Most upward shift activities were found to occur within a band of 300 m below the potential regional tree line, indicating land use as the most likely driver. Only 4% of the upward shifts were identified to rise above the potential regional tree line, thus indicating climate change. Conclusions: Land abandonment was the most dominant driver for the establishment of new forest areas, even at the tree line ecotone. However, a small fraction of upwards shift can be attributed to the recent climate warming, a fraction that is likely to increase further if climate continues to warm, and with a longer time-span between warming and measurement of forest cover.

Desenvolvimento de um curso on-line sobre o tema administração de medicamentos

O estudo descreveu o desenvolvimento de um curso on-line sobre o processo da administração de medicamentos - vias. Para tanto se utilizou o World Wide Web Course Tools (WebCT), que é um software que fornece várias ferramentas a supervisores e acesso a estudantes providos de uma senha a diversos ambientes. O material do curso foi subdivido em oito tópicos ilustrados: administração de medicamentos por via oral, sublingual, via parenteral, intradérmica, subcutânea, intramuscular, endovenosa e aplicação tópica e instilação, além das questões para avaliação de conhecimentos. Uma amostra de alunos de graduação da Escola de Enfermagem de Ribeirão Preto - USP avaliou positivamente o curso. Pretende-se agora inseri-lo em disciplina curricular do ensino de graduação, como um recurso adicional à aprendizagem dos alunos.

First-line therapies in inflammatory bowel disease.

Background and Aims: Medical therapy of inflammatory bowel disease (IBD) is becoming more complex, given the increasing choice of drugs to treat Crohn's disease (CD) and ulcerative colitis (UC). We aimed to summarize the current guidelines for first-line treatments in IBD. Methods: An extensive literature search with focus on the guidelines of the European Crohn's and Colitis Organisation for the diagnosis and treatment of CD and UC was performed. First-line treatments were defined as the following drug categories: 5-aminosalicylates, budesonide, systemic steroids, azathioprine, 6-mercaptopurine, methotrexate, infliximab, adalimumab and certolizumab pegol. The following drug categories were not included: cyclosporine and tacrolimus (not yet approved by Swissmedic for IBD treatment). Results: Treatment recommendations for the following clinically frequent situations are presented according to disease severity: ileocecal CD, colonic CD, proximal small bowel CD and perianal CD. For UC the following situations are presented: ulcerative proctitis, left-sided colitis and pancolitis. Conclusions: We provide a summary on the use of first-line therapies for clinically frequent situations in patients with CD and UC.

Panorama brasileiro do ensino de Enfermagem On-line

O objetivo deste estudo foi identificar os cursos de Ensino Superior Nacional de EAD por área de concentração, região geográfica, nível de formação e os cursos de EAD no ensino superior de Enfermagem. O método adotado foi um estudo exploratório descritivo em que foi realizado um levantamento nos sites e portais governamentais e não-governamentais relacionados à educação nacional e EAD das Instituições de Ensino Superior (IES) que praticam EAD. Nos resultados foram identificados apenas dois cursos de pós-graduação lato sensu oferecidos especificamente em Enfermagem. Assim, há necessidade de maior investimento das IES de Enfermagem na criação e avaliação de cursos de EAD, bem como de infra-estrutura e de implementação de uma política de capacitação tecnológica.

Gestión de encuestas on-line dinámicas con estímulo (GEODE)

El presente proyecto ha sido pergeñado como una aplicación que pretende resolver las dos carencias principales detectadas en los sistemas clásicos de encuestas on-line gratuitos: por un lado, resultan estáticos (en el sentido de que las encuestas no son dinámicas en función de las respuestas acumuladas) y, por otro, no ofrecen al individuo encuestado el conocimiento que necesita (como máximo devolverán información agrupada de acuerdo a los resultados globales obtenidos sin retornar un análisis comparativo del grupo frente a la del usuario).

Effectiveness of intermittent preventive treatment with sulfadoxine-pyrimethamine during pregnancy on placental malaria, maternal anaemia and birthweight in areas with high and low malaria transmission intensity in Tanzania.

OBJECTIVE: To assess the effectiveness of IPTp in two areas with different malaria transmission intensities. METHODS: Prospective observational study recruiting pregnant women in two health facilities in areas with high and low malaria transmission intensities. A structured questionnaire was used for interview. Maternal clinic cards and medical logs were assessed to determine drug intake. Placental parasitaemia was screened using both light microscopy and real-time quantitative PCR. RESULTS: Of 350 pregnant women were recruited and screened for placental parasitaemia, 175 from each area. Prevalence of placental parasitaemia was 16.6% (CI 11.4-22.9) in the high transmission area and 2.3% (CI 0.6-5.7) in the low transmission area. Being primigravida and residing in a high transmission area were significant risk factors for placental malaria (OR 2.4; CI 1.1-5.0; P = 0.025) and (OR 9.4; CI 3.2-27.7; P < 0.001), respectively. IPTp was associated with a lower risk of placental malaria (OR 0.3; CI 0.1-1.0; P = 0.044); the effect was more pronounced in the high transmission area (OR 0.2; CI 0.06-0.7; P = 0.015) than in the low transmission area (OR 0.4; CI 0.04-4.5; P = 0.478). IPTp use was not associated with reduced risk of maternal anaemia or low birthweight, regardless of transmission intensity. The number needed to treat (NNT) was four (CI 2-6) women in the high transmission area and 33 (20-50) in the low transmission area to prevent one case of placental malaria. CONCLUSION: IPTp may have an effect on lowering the risk of placental malaria in areas of high transmission, but this effect did not translate into a benefit on risks of maternal anaemia or low birthweight. The NNT needs to be considered, and weighted against that of other protective measures, eventually targeting areas which are above a certain threshold of malaria transmission to maximise the benefit.
