Abstract: larvae of culex eduardoi, culex bigoti, limatus durhamii and toxorhynchites were collected in a tyre that had been placed in a wood by a river bank. these larvae were present coexisting and in an individualized form. it was observed that toxorhynchites, culex bigoti and limatus durhamii were efficient in reducing the other two species's population. culex bigoti and toxorhynchites showed preference for culex quinquefasciatus larvae, while limatus durhamii preferred culex eduardoi. the most efficient predator was toxorhynchites, and the least efficient was limatus durhamii. the reduction of the preys' population density was statistically meaningful in the face of the three species considered as predators.

Abstract: INTRODU O: A utiliza o pelos Culicidae de recipientes contendo água para a coloca o de seus ovos, em área antropogênica, pode indicar plasticidade genética que os direcione evolutivamente no sentido da domicilia o. Nesse sentido, foram coletadas as diferentes espécies de Culicidae que colonizam recipientes alocados em mata ciliar, na área rural. MATERIAL E MéTODO: Foram instalados recipientes de pneu, plástico, lata e bambu, em mata ciliar, em área rural no Norte do Paraná, Brasil. RESULTADOS: Coletaram-se larvas de Cx. grupo coronator, Cx. declarator, Cx. laticlasper, Cx. (Melanoconion) sec o Spissipes, Cx. tatoi, Tr. compressum, Tr. pallidiventer, Ae. terrens, Cx. mollis, Cx. bigoti, Hg. leucocelaenus, Cx. eduardoi, Cx. quinquefasciatus, Li. durhamii e Toxorhynchites sp. As cinco primeiras espécies foram específicas de pneus. As duas espécies de Trichoprosopon ficaram restritas a bambu. Ae. terrens e Cx. mollis foram caletadas em pneu e bambu, Cx. bigoti foi coletada em pneu, lata e bambu, enquanto que Hg. leucocelaenus só n o foi encontrada em lata. As quatro últimas espécies foram coletadas em todos os tipos de recipientes. Cx. quinquefasciatus, Cx. eduardoi, Li. durhamii tiveram significante flutua o populacional. CONCLUS ES: O pneu caracterizou-se como o recipiente mais aceito pelos culicídeos. As áreas onde a mata ciliar esteve mais densa e o locais onde o solo esteve mais úmido foram os pontos com maior número de capturas. A mata ciliar, mesmo muito reduzida e alterada, foi suficiente para abrigar várias espécies de culicídeos. As espécies caputradas podem ser portadoras de plasticidade gênica que as capacitem a colonizar ambientes antropogênicos.

Abstract: Many literature citations state that Coleóptera of the family Dytiscidae are predators of larvae of Culicidae. In an area of primative forest, small receptacles of water were introduced in order to study ecology of Dytiscidae. A new species of the genus Copelatus was discovered and found to be a predator of mosquito larvae. Field observations of behavior colonization of receptacles and aspects of the controle of mosquito population were made. In the laboratory were studied resistance to dessication, dispersion, aquatic respiration, relationship with other predators and its influence upon development of Culicidae larvae. Copelatus appears to be an efficient agent of biological control of larva of Culicidae in small reservatories of water. Existem na literatura inúmeras cita es, referentes a Coleópteras da família Dytiscidae, incriminando-os como predador de larvas de Culicidae. Foi introduzido em uma área de mata primaria recipiente contendo água, com o objetivo de identificar um predador para as larvas de mosquito. Coletou-se um Dytiscidae, espécie nova do gênero Copelatus que exerce a o predatória sobre as larvas de mosquito. Estudou-se seu comportamento em campo observando-se a coloniza o dos recipientes e sua atua o positiva no controle de Culicidae. Em laboratório foi estudado Fatores de Resistência a desseca o, dispers o, respira o aquática, comportamento frente a outro predador e influência sobre o desenvolvimento das larvas de Culicidae. Copelatus mostrou-se eficiente agente de controle biológico das larvas de Culicidae em pequenos reservatórios de água.

Abstract: Simuliidae have been considered object of concern due to their hemophagia, anthropophilic habits and high proliferation, causing discomfort to the population, damages to agricultural activities and rural tourism, besides being pathogens vectors. With the purpose of understanding the community structure and specific diversity of these insects, a survey of the species was conducted in three streams in an ecological park in Telêmaco Borba – Paraná, Brazil. Immature specimens were collected in mineral and vegetable substrates on the riverbanks. Chemical and physical analyses of the water were carried out. The Simuliidae collection included 14,397 individuals, being 14,150 larvae and 247 pupae. The following species were identified: Simullium subnigrum, S. subpallidum, S. rubrithorax, S. incrustatum, S. pertinax, S. inaequale, S. anamariae, S. rubiginosum, S. travassosi, S. riograndense and S. dinelli. This is the first registry of S. rubiginosum and S. dinelli in the State of Paraná. The lesser-impacted areas presented greater diversity. However, the impacted areas presented an abundance of borrachudos, represented by a single species, S. rubrithorax. It was concluded that preservation areas with lotic waters and riparian forest are considered a refuge area for Simuliidae species. Impact of anthropical activities upon the environment interferes in the dynamics of species, favoring one or more of them, which proliferate and predominate. Os simulídeos têm sido objeto de preocupa o devido ao seu hábito hematófago, forte antropofilia e alta prolifera o, causando desconforto à popula o, prejuízos em atividades agropecuárias e de turismo rural, além de serem vetores de patógenos. Objetivando conhecer a estrutura de comunidade e diversidade específica desses insetos, foi realizado o levantamento de espécies em três riachos de um parque ecológico em Telêmaco Borba – Paraná. Coletaram-se imaturos em substratos minerais e vegetais no leito dos rios. Efetuaram-se análises físicas e químicas da água. Foram coletados 14397 indivíduos, sendo 14150 larvas e 247 pupas de simulídeos. Identificaram-se as espécies Simullium subnigrum, S. subpallidum, S. rubrithorax, S. incrustatum, S. pertinax, S. inaequale, S. anamariae, S. rubiginosum, S. travassosi, S. riograndense e S. dinelli. Este é o primeiro registro de S. rubiginosum e S. dinelli para o Estado do Paraná. As áreas de menor impacto apresentaram maior diversidade, entretanto áreas impactadas apresentaram maior abundancia de borrachudos, representados por apenas uma espécie, S. rubrithorax. Conclui-se que áreas de pre
Comparison of RIFLE with and without urine output criteria for acute kidney injury in critically ill patients: a task still not concluded!

Critical Care , 2013, DOI: 10.1186/cc11911
Abstract: Ameen Abu-Hanna, Kama A Wlodzimirow, Marcus Schultz and Catherine SC BoumanWe agree with Lopes and Jorge that multivariate analysis should be attempted when testing whether RIFLESCr is associated with higher mortality than RIFLESCr+UO. Essentially the question is whether the group (hereafter G1) of patients with AKI based on the RIFLESCr criteria (regardless of UO) is at higher risk of death than the group (hereafter G2) classified as having AKI based on the UO criteria only. Additional analysis, not reported in [1], shows that out of admission type, age, gender, weight, Acute Physiology and Chronic Health Evaluation (APACHE) score, Simplified Acute Physiology Score (SAPS), cardiopulmonary resuscitation, and length of stay, only SAPS was a confounder. Before adjustment for SAPS, patients in G1 had 1.64 times the odds of dying than those in G2. After adjustment for SAPS, the OR was reduced to 1.45 (P = 0.0004), still confirming our findings, which are in agreement with those of the other study [3].The seeming contradiction between our findings and those of Lopes and colleagues [4] is easily explained by the significant differences in case mix. In our study, 48.6% of the RIFLESCr+UO AKI patients were classified as having AKI on the basis of the UO criteria only [1] versus 5.6% in the study by Lopes and colleagues [4]. Differences in case mix may be attributable to the different inclusion criteria, the Modification of Diet in Renal Disease (MDRD)-based estimation of baseline SCr in all patients in the previous study [4], which may overestimate AKI based on SCr [5], and the outcome definition. All of these are important factors to consider when comparing studies.AKI: acute kidney injury; AUROC: area under the receiver operator characteristic; OR: odds ratio; RIFLE: Risk Injury Failure Loss End-stage renal disease; RIFLESCr: RIFLE criteria based on the serum creatinine criteria only; RIFLESCr+OU: RIFLE criteria based on serum creatinine and urine output criteria; SAPS: S
Sepsis as a major determinant of outcome in critically ill HIV/AIDS patients: don't forget acute kidney injury

Critical Care , 2012, DOI: 10.1186/cc11870
Abstract: Rodrigo Teixeira Amancio, André Miguel Japiassú and Fernando Augusto BozzaAcute renal failure (ARF) is one of the major determinants of hospital outcome in the critically ill population, and severe sepsis is the main cause of ARF in this setting [5]. Patients with HIV/AIDS show a predisposition to renal dysfunction, as the HIV and antiretroviral drugs can lead to renal tubular dysfunction [6]. Lopes and colleagues [3,4] have reported that ARF is independently associated with hospital mortality of critically ill patients with HIV.We evaluated 88 HIV-positive critically ill patients, seeking the main risk factors for mortality [1]. Severe sepsis was the major factor associated with 28-day and 6-month mortality. CD4 cell count, viral load, and the use of antiretrovirals were not associated with survival. As suggested by Lopes and Jorge, we reanalyzed the data about organ dysfunctions in that cohort, targeting hospital outcome. Nonsurvivors presented higher rates of renal (63% versus 33%, P = 0.01) and hematological (42% versus 16%, P = 0.009) dysfunctions than survivors of HIV/AIDS. We included these organ dysfunctions in a new multivariate analysis; severe sepsis remained the main factor associated with hospital survival (odds ratio (OR) 4.2, 95% confidence interval (CI) 1.2 to 14.2, P = 0.02), and renal (OR 2.6, 95% CI 0.9 to 7.4, P = 0.06) and hematological (OR 2.7, 95% CI 0.9 to 8.5, P = 0.08) dysfunction had borderline results (Table 1). We also reevaluated our current cohort, reaching 139 patients with HIV, and the presence of renal failure was related to poorer prognosis but was not associated with hospital mortality in the multivariate analysis (OR 1.9, 95% CI 0.8 to 4.4, P = 0.15). We agree that renal dysfunction, especially when associated with severe sepsis, can reduce survival among critically ill patients with HIV/AIDS.AKI: acute kidney injury; ARF: acute renal failure; CI: confidence interval; OR: odds ratio.The authors declare that they have no competing
Kidney function decline after a non-dialysis-requiring acute kidney injury is associated with higher long-term mortality in critically ill survivors

Critical Care , 2012, DOI: 10.1186/cc11860
Abstract: Chun-Fu Lai, Vin-Cent Wu, Wen-Je Ko and Kwan-Dun WuWe thank Lopes and Jorge for their interest in our article [1]. We agree that sepsis should be taken into consideration in evaluating AKI outcomes. The presence of sepsis and the etiology of AKI have been identified as important factors affecting prognosis after an AKI [5].Our prospectively collected NSARF (National Taiwan University Study Group on Acute Renal Failure) database, operating since 2002, did not contain the variables of the presence of sepsis and etiology of AKI at that time. Therefore, we could not analyze the influence of sepsis. We acknowledged this as a limitation and discussed it in the article. We included many factors in the final analysis model, including maximum RIFLE (risk, injury, failure, loss, and end-stage kidney criteria) stage, mean arterial pressure, serum lactate levels, inotropic equivalent, and APACHE II (acute physiology and chronic health evaluation II) and SOFA (sequential organ failure assessment) scores, and these could partially account for the impact of sepsis on AKI outcomes. These clinical factors had been shown to be associated with septic AKI in previous studies [3,4].AKI: acute kidney injury; ICU: intensive care unit.The authors declare that they have no competing interests.JAL and SJ drafted the letter, revised it critically for important intellectual content, and read and approved the final manuscript.
