Reproduction of mosquitoes (Diptera: Culicidae) in Santa Cruz, Santiago island, Cape Verde Islands
(2012)
Mosquitoes are dipterous insects with an important role in the transmission of diseases like malaria and dengue. During a dengue fever outbreak in the Cape Verde Islands in 2009, several studies were undertaken to support vector control. The present study was carried out in the district of Santa Cruz, Santiago island, to evaluate previous measures taken to control mosquito populations. Results show that mosquitoes use domestic water containers to breed. Barrels, drums and pots were all used. Of these, drums were most frequently found being infested with mosquito larvae or pupae. Morphological identification showed that Anopheles arabiensis and Aedes aegypti were present in the study area. Ae. aegypti was the commonest of the two and the only one found throughout the study area. Results show that socio-economic factors influence container positivity.
Antisynthetase syndrome (ASSD) is a rare clinical condition that is characterized by the occurrence of a classic clinical triad, encompassing myositis, arthritis, and interstitial lung disease (ILD), along with specific autoantibodies that are addressed to different aminoacyl tRNA synthetases (ARS). Until now, it has been unknown whether the presence of a different ARS might affect the clinical presentation, evolution, and outcome of ASSD. In this study, we retrospectively recorded the time of onset, characteristics, clustering of triad findings, and survival of 828 ASSD patients (593 anti-Jo1, 95 anti-PL7, 84 anti-PL12, 38 anti-EJ, and 18 anti-OJ), referring to AENEAS (American and European NEtwork of Antisynthetase Syndrome) collaborative group’s cohort. Comparisons were performed first between all ARS cases and then, in the case of significance, while using anti-Jo1 positive patients as the reference group. The characteristics of triad findings were similar and the onset mainly began with a single triad finding in all groups despite some differences in overall prevalence. The “ex-novo” occurrence of triad findings was only reduced in the anti-PL12-positive cohort, however, it occurred in a clinically relevant percentage of patients (30%). Moreover, survival was not influenced by the underlying anti-aminoacyl tRNA synthetase antibodies’ positivity, which confirmed that antisynthetase syndrome is a heterogeneous condition and that antibody specificity only partially influences the clinical presentation and evolution of this condition.
