TL;DR: Conclui-se da analise that massas de agua orladas por mata ciliar reduzida podem funcionar como refugio para alguns Culicidae e esta condicao pode contribuir decisivamente para o processo de domiciliacao de especies deste grupo.
Abstract: Objetivando-se conhecer as especies de Culicidae aptas a colonizarem ambiente de um ribeirao com mata ciliar reduzida e localizado na regiao Sul do Brasil, foram realizadas capturas com auxilio de rede para coleta de insetos aquaticos. Foram apanhadas as seguintes especies: Aedes crinifer, Aedomya squamipennis, Anopheles fluminensis, An. intermedius, An. albitarsis, An. argyritarsis, An. evansae, An. galvaoi, An. oswaldoi, An. strodei, An. triannulatus, Chagasia fajardi, Culex bidens, Cx. grupo coronator, Cx. eduardoi, Cx. mollis, Cx. quinquefasciatus, Cx. coppenamensis, Cx. vaxus, Cx. grupo inhibitator, Cx. intrincatus, Cx. (Melanoconion) sp., Psorophora saeva (?) e Uranotaenia pulcherrima. Para as especies em que foi capturada uma amostra tida como representativa, foram estudadas a distribuicao ao longo da area pesquisada, a flutuacao populacional e a correlacao com fatores fisicos do ambiente. Conclui-se da analise que massas de agua orladas por mata ciliar reduzida podem funcionar como refugio para alguns Culicidae e esta condicao pode contribuir decisivamente para o processo de domiciliacao de especies deste grupo.

TL;DR: The incidence of DDI-related ADRs in elderly outpatients was significant, and most of the events presented important clinical consequences.
Abstract: Purpose. The primary objective of this study was to investigate the incidence of drug-drug interactions (DDIs) related to adverse drug reactions (ADRs) in elderly outpatients who attended public primary healthcare units in a southeastern region of Brazil. The secondary objective was to investigate the possible predictors of DDI-related ADRs. Methods. A prospective cohort study was conducted between November 1, 2010, and November 31, 2011, in the primary public healthcare system in the Ourinhos micro-region in Brazil. Patients who were at least 60 years old, with at least one potential DDI, were eligible for inclusion in the study. Eligible patients were assessed by clinical pharmacists for DDI-related ADRs for 4 months. The causality of DDI-related ADRs was assessed independently by four clinicians using three decisional algorithms. The incidence of DDI-related ADRs during the study period was calculated. Logistic regression analysis was used to study DDI-related ADR predictors. Results. A total of 433 patients completed the study. The incidence of DDI-related ADRs was 6.5%. A multivariate analysis indicated that the adjusted odds ratios (ORs) rose from 0.91 (95% confidence interval [CI] = 0.75-1.12, p = 0.06) in patients aged 65-69 years to 4.40 (95% CI = 3.00-6.12, p < 0.01) in patients aged 80 years or older. Patients who presented two to three diagnosed diseases presented lower adjusted ORs (OR = 0.93 [95% CI = 0.68-1.18, p = 0.08]) than patients who presented six or more diseases (OR = 1.12 [95% CI = 1.02-2.01, p < 0.01]). Elderly patients who took five or more drugs had a significantly higher risk of DDI-related ADRs (OR = 2.72 [95% CI = 1.92-3.12, p < 0.01]) than patients who took three to four drugs (OR = 0.93 [95% CI = 0.74-1.11, p = 0.06]). No significant difference was found with regard to sex (OR = 1.08 [95% CI 0.48-2.02, p = 0.44]). Conclusion. The incidence of DDI-related ADRs in elderly outpatients was significant, and most of the events presented important clinical consequences. Because clinicians still have difficulty managing this problem, highlighting the factors that increase the risk of DDI-related ADRs is essential. Polypharmacy was found to be a significant predictor of DDI-related ADRs in our sample. This article is open to POST-PUBLICATION REVIEW.

TL;DR: It is believed that the major cause for the loss of organic diversity is not rational exploitation, but the destruction of habitats, a result of the expansion of irrational human activities.
Abstract: This study was carried out with the objective of evaluating if the size of forest fragments affects the diversity of bat species In order to do that, seven fragments were studied in Londrina, Parana: five small fragments, whose areas varied between 1 and 10 ha; a fragment which is considered medium-sized (Parque Municipal Arthur Thomas - 85,47 ha); and a large fragment (Parque Estadual Mata dos Godoy - 680 ha) Thirty three species were collected Ten species were common to all three types of fragments: Chrotopterus auritus (Peters, 1856), Carollia perspicillata (Linnaeus, 1758), Artibeus fimbriatus Gray, 1838, Artibeus lituratus (Olfers, 1818), Platyrrhinus lineatus (E Geoffroy, 1810), Pygoderma bilabiatum (Wagner, 1843), Sturnira lilium (E Geoffroy, 1810), Vampyressa pusilla (Wagner, 1843), Eptesicus brasiliensis (Desmarest, 1819), and Myotis nigricans (Schinz, 1821) Eight species were only found in the large fragment: Noctilio albiventris Desmarest, 1818, Glossophaga soricina (Pallas, 1766), Uroderma bilobatum Peters, 1866, Diaemus youngi (Jentink,1893), Diphylla ecaudata Spix, 1823, Eptesicus furinalis (d'Orbigny, 1847), Histiotus velatus (I Geoffroy, 1824) and Myotis levis (I Geoffroy, 1824) Five were only found in the small fragments: Noctilio leporinus (Linnaeus, 1758), Phyllostomus discolor Wagner, 1843, Chiroderma villosum Peters, 1860, Eptesicus sp e Rogheessa tumida H Allen, 1866 Chiroderma doriae, which is threatened by extinction, was captured in the large fragment and in one of the small fragments; M ruber, also threatened by extinction, was captured in the medium-sized and large fragments We believe that the major cause for the loss of organic diversity is not rational exploitation, but the destruction of habitats, a result of the expansion of irrational human activities
