A importância do Anopheles darlingi Root, 1926 e Anopheles marajoara Galvão e Damasceno, 1942 na transmissão de malária no município de Macapá/AP - Brasil

A malária no município de Macapá é principalmente peri urbana, áreas estas caracterizadas por ressaca, pela presença de fragmentos de floresta e assentamentos desordenados (invasões). O objetivo deste estudo foi verificar a importância dos Anopheles darlingi e Anopheles marajoara na transmissão de malária em Macapá. O estudo foi realizado de outubro de 2007 a setembro de 2008, na comunidade de Lagoa dos Índios, Macapá. Foram coletados 4.601 mosquitos, dos quais 3.029 foram Anopheles marajoara (65,8%), 917 Anopheles darlingi (19,9%), 429 Anopheles braziliensis (9,3%), 208 Anopheles triannulatus (4,5%), 18 Anopheles peryassui (0,4%) e cinco Anopheles nuneztovari (0,1%). Apenas 32,8% dos espécimes foram coletadas no intradomicilio (1.511) e 67,2% no peridomicilio (3.090). O Indice de Picada Homem Hora do An. darlingi no intradomicilio variou entre 0 a 6,5 e no peridomicilio de 0 a 22 picadas homem hora. Já para o An. marajoara a variaçao foi de 0 a 22 no intradomicilio e de 0 a 175,5 no peridomicilio. A analise das exúvias e da dissecção de genitália resultaram na confirmaçao das duas espécies estudadas, An. darlingi e An. marajoara, e que o An. marajoara é a única espécie do complexo albitarsis circulante na área. A abundância dos vetores flutuou associada com o padrão sazonal das chuvas. An. darlingi é mais abundante no final e inicio das chuvas, enquanto o An. marajoara esteve presente em alta densidade durante todo o período de chuvas. Dos 4.601 mosquitos testados, 100 foram positivos para plasmódios humanos pelo método de ELISA, resultando em uma taxa de infecção de 2,17%. Dos 3.029 An. marajoara testados 71 (2,34%) foram positivos e dos 917 An. darlingi, 28 (3,05%). Este estudo demonstrou que as duas espécies estudadas mantêm a transmissão de malária durante todo o ano, ratificando assim a importância das mesmas.

Periostin as a modulator of chronic cardiac remodeling after myocardial infarction

OBJECTIVE: After acute myocardial infarction, during the cardiac repair phase, periostin is released into the infarct and activates signaling pathways that are essential for the reparative process. However, the role of periostin in chronic cardiac remodeling after myocardial infarction remains to be elucidated. Therefore, the objective of this study was to investigate the relationship between tissue periostin and cardiac variables in the chronic cardiac remodeling induced by myocardial infarction. METHODS: Male Wistar rats were assigned to 2 groups: a simulated surgery group (SHAM; n = 8) and a myocardial infarction group (myocardial infarction; n = 13). After 3 months, morphological, functional and biochemical analyses were performed. The data are expressed as means±SD or medians (including the lower and upper quartiles). RESULTS: Myocardial infarctions induced increased left ventricular diastolic and systolic areas associated with a decreased fractional area change and a posterior wall shortening velocity. With regard to the extracellular matrix variables, the myocardial infarction group presented with higher values of periostin and types I and III collagen and higher interstitial collagen volume fractions and myocardial hydroxyproline concentrations. In addition, periostin was positively correlated with type III collagen levels (r = 0.673, p = 0.029) and diastolic (r = 0.678, p = 0.036) and systolic (r = 0.795, p = 0.006) left ventricular areas. Considering the relationship between periostin and the cardiac function variables, periostin was inversely correlated with both the fractional area change (r = -0.783, p = 0.008) and the posterior wall shortening velocity (r = -0.767, p = 0.012). CONCLUSIONS: Periostin might be a modulator of deleterious cardiac remodeling in the chronic phase after myocardial infarction in rats.

Biological aspects of Harmonia axyridis in comparison with Cycloneda sanguinea and Hippodamia convergens

The objective of this work was to evaluate the development, survival, reproductive capacity, and longevity of the Asian ladybug Harmonia axyridis in comparison with Cycloneda sanguinea and Hippodamia convergens. Coccinellid larvae and adults were fed daily with Schizaphis graminum. Ten couples of each species were isolated for evaluation of the adult phase. The duration of the larval stage of H. axyridis is the longest (10.2 days) and its adults are the heaviest (29.7 mg) compared with C. sanguinea and H. convergens. The three species showed similar percentages of survival during the developmental stages. An average of 82% of C. sanguinea, H. axyridis, and H. convergens larvae reached adulthood, which indicates that temperature (25°C) and the offered prey are favorable to coccinellid development. Harmonia axyridis produces a higher total number of eggs per female (1,029.2) than the other evaluated species. However, H. axyridis, which lives for an average of 147.2 days, does not show a significantly greater longevity than C. sanguinea (87.2 days) and H. convergens (134.3 days).

Prevalence and risk factors associated with wheezing in the first year of life

Objective: to investigate the prevalence and risk factors associated with wheezing in infants in the first year of life.Methods: this was a cross-sectional study, in which a validated questionnaire (Estudio Internacional de Sibilancias en Lactantes - International Study of Wheezing in Infants - EISL) was applied to parents of infants aged between 12 and 15 months treated in 26 of 85 primary health care units in the period between 2006 and 2007. The dependent variable, wheezing, was defined using the following standards: occasional (up to two episodes of wheezing) and recurrent (three or more episodes of wheezing). The independent variables were shown using frequency distribution to compare the groups. Measures of association were based on odds ratio (OR) with a confidence interval of 95% (95% CI), using bivariate analysis, followed by multivariate analysis (adjusted OR [aOR]).Results: a total of 1,029 (37.7%) infants had wheezing episodes in the first 12 months of life; of these, 16.2% had recurrent wheezing. Risk factors for wheezing were family history of asthma (OR = 2.12; 95% CI: 1.76-2.54) and six or more episodes of colds (OR = 2.38; 95% CI: 1.91-2.97) and pneumonia (OR = 3.02; 95% CI: 2.43-3.76). For recurrent wheezing, risk factors were: familial asthma (aOR = 1.73; 95% CI: 1.22-2.46); early onset wheezing (aOR = 1.83; 95% CI: 1.75-3.75); nocturnal symptoms (aOR = 2.56; 95% CI: 1.75-3.75), and more than six colds (aOR = 2.07; 95% CI 1.43-.00).Conclusion: the main risk factors associated with wheezing in Fortaleza were respiratory infections and family history of asthma. Knowing the risk factors for this disease should be a priority for public health, in order to develop control and treatment strategies. (C) 2013 Sociedade Brasileira de Pediatria.

Intra-abdominal pressure as a predictor of acute kidney injury in postoperative abdominal surgery

Objectives: The purpose of this study was to determine if intra-abdominal pressure (IAP) could predict acute renal injury (AKI) in the postoperative period of abdominal surgeries, and which would be its cutoff value. Patients and methods: A prospective observational study was conducted in the period from January 2010 to March 2011 in the Intensive Care Units (ICUs) of the University Hospital of Botucatu Medical School, UNESP. Consecutive patients undergoing abdominal surgery were included in the study. Initial evaluation, at admission in ICU, was performed in order to obtain demographic, clinical surgical and therapeutic data. Evaluation of IAP was obtained by the intravesical method, four times per day, and renal function was evaluated during the patient's stay in the ICU until discharge, death or occurrence of AKI. Results: A total of 60 patients were evaluated, 16 patients developed intra-abdominal hypertension (IAH), 45 developed an abnormal IAP (>7 mmHg) and 26 developed AKI. The first IAP at the time of admission to the ICU was able to predict the occurrence of AKI (area under the receiver-operating characteristic curve was 0.669; p=0.029) with the best cutoff point (by Youden index method) >= 7.68 mmHg, sensitivity of 87%, specificity of 46% at this point. The serial assessment of this parameter did not added prognostic value to initial evaluation. Conclusion: IAH was frequent in patients undergoing abdominal surgeries during ICU stay, and it predicted the occurrence of AKI. Serial assessments of IAP did not provided better discriminatory power than initial evaluation.
