Epidemiology of bacteremia in a pediatric population - A 10-year study.

Introduction: With the widespread introduction of conjugate meningococcal and pneumococcal vaccines, the prevalence and etiology of invasive bacterial infections have changed. We aimed to review all cases of bacteremia in a level II pediatric department over a ten-year period in the post-pneumococcal conjugate vaccine era.

Methods: We reviewed all positive blood cultures (BC) obtained in our department between 2007 and 2016.

Dynamics and Determinants of SARS-CoV-2 RT-PCR Testing on Symptomatic Individuals Attending Healthcare Centers during 2020 in Bahia, Brazil.

RT-PCR testing data provides opportunities to explore regional and individual determinants of test positivity and surveillance infrastructure. Using Generalized Additive Models, we explored 222,515 tests of a random sample of individuals with COVID-19 compatible symptoms in the Brazilian state of Bahia during 2020. We found that age and male gender were the most significant determinants of test positivity.

[Venous Thromboembolism in Pediatric Age: A 15 Year Retrospective Review].

Introduction: Pulmonary thromboembolism and deep venous thrombosis occur in pediatric age, with unknown incidence, morbidity and mortality. Our aim is to review the epidemiology, clinical presentation, complementary diagnostic tests and prognosis of patients with pulmonary thromboembolism and deep venous thrombosis.

Material And Methods: Retrospective, descriptive and analytical study of pediatric patients admitted to a Level II hospital for pulmonary thromboembolism and deep venous thrombosis, between 2000 and 2014.

High susceptibility of Bt maize to aphids enhances the performance of parasitoids of lepidopteran pests.

Concerns about possible undesired environmental effects of transgenic crops have prompted numerous evaluations of such crops. So-called Bt crops receive particular attention because they carry bacteria-derived genes coding for insecticidal proteins that might negatively affect non-target arthropods. Here we show a remarkable positive effect of Bt maize on the performance of the corn leaf aphid Rhopalosiphum maidis, which in turn enhanced the performance of parasitic wasps that feed on aphid honeydew.
