Studies on the parasitology of ectoparasitic bat flies are scarce, and they are needed to identify patterns in parasitism. Hence, in the present study, we assessed community composition, prevalence, average infestation intensity, and specificity in the fly-bat associations in Brazilian tropical dry forests. In order to do that, we used the parasitological indices known as prevalence and average infestation intensity, along with an index of host specificity. We collected 1098 bat flies of 38 species. Five of the associations found are new to Brazil, 9 are new to southeastern Brazil, and 10 are new to science. Average infestation intensity varied from 1 to 9 and prevalence 0 to 100 %. In terms of specificity, 76 % of the bat flies were associated to a single host (monoxenic). These results highlight the low capacity of bat flies to survive on a not usual host especially due to an immunological incompatibility between parasites and hosts and dispersal barriers.

In Brazil, most studies involving parasites of bats (bat flies) treat the mid-west, south-east, and south of the country. This work aimed to characterize the ectoparasites community associated with bats in the Atlantic forest in the state of Sergipe, north-eastern Brazil. Sampling was conducted between January and June 2013 in the Serra de Itabaiana National Park (PNSI) and between November 2013 and June 2015 in the Wildlife Refuge Mata do Junco (RVSMJ). Parasitological indexes were determined, and the influence of host sex and the seasonality in prevalence rates and mean intensity for the most abundant parasites was evaluated. Some 129 parasites were collected in PNSI and 296 in RVSMJ, and 100 and 70.6 %, respectively, belong to the family Streblidae. The differences in parasitological rates in Sergipe in relation to other studies may be associated with the environmental characteristics and the composition of the host community. The influence of sex and the seasonal prevalence of Speiseria ambigua and Trichobius joblingi, associated with Carollia perspicillata, may be associated with a lower rate of female captures and low sampling in the dry season. This is a pioneer study in Sergipe that reveals the occurrence of 16 species of streblids and representatives of Acari and Basilia spp., highlighting the need for more studies to increase the wealth and understanding of host-parasite associations in the state.

Objetivo: caracterizar a utilização de antidepressivos no manejo da depressão pós-parto. Método: empregou-se uma revisão integrativa de literatura, das bases de dados PubMed e Biblioteca Virtual em Saúde, com aplicação de descritores, visando responder a pergunta norteadora do trabalho, entre os dias 25 de fevereiro e 10 de março de 2019. Com base nos critérios de inclusão e exclusão, foram selecionados 23 artigos que, posteriormente, foram submetidos à categorização. Resultados: a sertralina deve ser a droga de escolha para o tratamento farmacológico da depressão puerperal. Constatou-se também, que a utilização profilática de antidepressivos em mulheres susceptíveis é contestável e pouco se sabe sobre os possíveis efeitos colaterais. Ademais, foi encontrado que não há consenso sobre a superioridade da terapia farmacológica em detrimento às psicoterapias. Conclusão: há  evidencias que fundamentam o uso de sertralina, paroxetina, duloxetina, nortriptilina e imipramina para tratar mulheres com depressão pós-parto, sendo a amamentação sempre recomendada. Ressalta-se que emerge a necessidade de estudos com amostras representativas para validar ou restringir o uso de psicofármacos na profilaxia da depressão puerperal.
