Report on ticks collected in the Southeast and Mid-West regions of Brazil: analyzing the potential transmission of tick-borne pathogens to man

Specimens of ticks were collected in 1993, 1996, 1997, and 1998, mostly from wild and domestic animals in the Southeast and Mid-West regions of Brazil. Nine species of Amblyommidae were identified: Anocentor nitens, Amblyomma cajennense, Amblyomma ovale, Amblyomma fulvum, Amblyomma striatum, Amblyomma rotundatum, Boophilus microplus, Boophilus annulatus, and Rhipicephalus sanguineus. The potential of these tick species as transmitters of pathogens to man was analyzed. A Flaviviridade Flavivirus was isolated from Amblyomma cajennense specimens collected from a sick capybara (Hydrochaeris hydrochaeris). Amblyomma cajennense is the main transmitter of Rickettsia rickettsii (=R. rickettsi), the causative agent of spotted fever in Brazil. Wild mammals, mainly capybaras and deer, infested by ticks and living in close contact with cattle, horses and dogs, offer the risk of transmission of wild zoonosis to these domestic animals and to man.

Baumol revisitado: Que futuro para o peso do sector da saúde em portugal?

A “Doença de Baumol” refere que o baixo crescimento da produtividade no sector da saúde e a uniformidade dos salários da economia como um todo, fazem com que os custos neste sector, dito “estagnado”, sejam inevitavelmente crescentes o longo do tempo. Este facto coloca uma pressão real acrescida na sustentabilidade dos Orçamentos de Estado na generalidade dos países desenvolvidos, que é difícil de resolver e para o qual se torna urgente desenvolver métodos de análise e solução eficazes. Concretamente, partindo de hipóteses cruciais, a fracção de despesa pública em saúde em Portugal, poderá atingir 9,5% do PIB já em 2010 e 20,9% do mesmo em 2030. Dado que não se põe a hipótese de conter custos baixando a qualidade dos cuidados médicos proporcionados pelo sector público, os dois caminhos mais plausíveis no curto prazo, são aumentar a eficiência ou incrementar o financiamento e provisão pelo sector privado e outras instituições de cariz social.

Potential use of Piper nigrum ethanol extract against pyrethroid-resistant Aedes aegypti larvae

Fractionation of Piper nigrum ethanol extract, biomonitored by assays on pyrethroid-resistant Aedes aegypti larvae yielded isolation of the larvicidal amides piperolein-A and piperine. Comparing LC50 values, the ethanol extract (0. 98 ppm) was the most toxic, followed by piperolein-A (1. 46ppm) and piperine (1. 53ppm).
