Association of insularity and body condition to cloacal bacteria prevalence in a small shorebird
Do islands harbour less diverse disease communities than mainland? The island biogeography theory predicts more diverse communities on mainland than on islands due to more niches, more diverse habitats and availability of greater range of hosts. We compared bacteria prevalences ofCampylobacter,ChlamydiaandSalmonellain cloacal samples of a small shorebird, the Kentish plover (Charadrius alexandrinus) between two island populations of Macaronesia and two mainland locations in the Iberian Peninsula. Bacteria were found in all populations but, contrary to the expectations, prevalences did not differ between islands and mainland. Females had higher prevalences than males forSalmonellaand when three bacteria genera were pooled together. Bacteria infection was unrelated to bird's body condition but females from mainland were heavier than males and birds from mainland were heavier than those from islands. Abiotic variables consistent throughout breeding sites, like high salinity that is known to inhibit bacteria growth, could explain the lack of differences in the bacteria prevalence between areas. We argue about the possible drivers and implications of sex differences in bacteria prevalence in Kentish plovers
Safety and efficacy of fenproporex for obesity treatment: a systematic review
ABSTRACT OBJECTIVE To evaluate clinical evidence on the safety and efficacy of fenproporex for treating obesity. METHODS MEDLINE, LILACS and Cochrane Controlled Trials Register were searched as well as references cited by articles and relevant documents. Two authors independently assessed the studies for inclusion and regarding risk of bias, collected data, and accuracy. Eligible studies were all those placebo-controlled that provided data on the efficacy and safety of Fenproporex to treat obesity. RESULTS Only four controlled studies met the inclusion criteria. One randomized, placebo-controlled trial on Fenproporex was found on electronic databases. Three placebo-controlled studies (in non-indexed journals) were identified by hand-searching. Patients with cardiovascular and other comorbidities were excluded in all studies. Trials lasted from 40 to 364 days and doses ranged from 20 to 33.6 mg/d. All controlled studies found that weight loss among Fenproporex-treated patients was greater than that produced by the placebo, but drug effect was modest. Fenproporex produced additional weight reductions of 4.7 kg (one year), 3.8 kg (six months) and 1.55 kg (two months) in average, in relation to diet and exercise only (three trials). Insomnia, irritability, and anxiety were the most frequently reported side effects in the four studies. CONCLUSIONS There is a paucity of randomized, placebo-controlled trials on Fenproporex and those identified here present major methodological flaws. These studies suggest that Fenproporex is modestly effective in promoting weight loss. Nonetheless, they failed to provide evidence that it reduces obesity-associated morbidity and mortality. Data from these studies are insufficient to determine the risk-benefit profile of Fenproporex. Abuse potential and amphetamine-like adverse effects are causes for concern
Na parada do lazer: delineando as ações de lazer em ONGs LGBT de Belo Horizonte
O presente estudo objetivou diagnosticar e analisar as ações de lazer das Organizações Não Governamentais ligadas ao Movimento LGBT de Belo Horizonte/MG. Assim, apresentamos como proposta metodológica a pesquisa documental combinada com a de campo, aplicando a imersão no campo e as entrevistas semiestruturadas como instrumentos de coleta de dados. Foram analisadas duas instituições, sendo entrevistados seis profissionais que atuam no âmbito do lazer. Os objetivos dessas ações variam, cabendo a elas desde o trabalho da autoestima até o empoderamento desse público visando a seu protagonismo social. Há uma multiplicidade de ações que envolvem os diversos conteúdos do lazer, das artes às atividades físicas. Assim, este trabalho traz algumas provocações que convidam a pensar o campo de atuação profissional em lazer em ONGs LGBT: o planejamento participativo das ações; a utilização e apropriação dos espaços públicos para o lazer; os investimentos no setor; e a conscientização do lazer como direito
