Epidemiological factors associated with Toxoplasma gondii infection in postpartum women treated in the public healthcare system of Goiânia, State of Goiás, Brazil.

Introduction: Knowledge of the epidemiological profile and risk factors for Toxoplasma gondii infection among postpartum women is a relevant issue, because this protozoan can be vertically transmitted to the developing fetus, which can cause severe and debilitating disease. The aim of this study was to assess the risk factors associated with T. gondii infection in postpartum women in Goiânia, GO, Brazil.

IgG Avidity Test in Congenital Toxoplasmosis Diagnoses in Newborns.

The goal of this study was to investigate the importance of IgG avidity testing in newborns (NBs) diagnosed with early congenital toxoplasmosis. We collected samples from 88 puerperae infected by Toxoplasma gondii (T. gondii) and their NBs (48 acutely-infected puerperae (AIP) and 40 chronically-infected puerperae (CIP)), from two public maternity hospitals in Goiania city, Goias, Brazil, from 2010 to 2015.

Evaluating genotoxic risks in Brazilian public health agents occupationally exposed to pesticides: a multi-biomarker approach.

This is the first study demonstrating genotoxic effects and whole transcriptome analysis on community health agents (CHAs) occupationally exposed to pesticides in Central Brazil. For the transcriptome analysis, we found some genes related to Alzheimer's disease (LRP1), an insulin-like growth factor receptor (IGF2R), immunity genes (IGL family and IGJ), two genes related to inflammatory reaction (CXCL5 and CCL3), one gene related to maintenance of cellular morphology (NHS), one gene considered to be a strong apoptosis inductor (LGALS14), and several transcripts of the neuroblastoma breakpoint family (NBPF). Related to comet assay, we demonstrated a significant increase in DNA damage, measured by the olive tail moment (OTM), in the exposed group compared to the control group.

Evaluation of the accuracy of parasitological techniques for the diagnosis of intestinal parasites in cats.

The accuracy of the parasitological techniques of Willis, Hoffman-Pons-Janer or Lutz (HPLJ), Sheather and Faust was evaluated in fecal samples from stray cats caught by the Zoonosis Control Center in Goiânia, Goiás, Brazil. These four techniques were applied separately to analyze 154 fecal samples, and their accuracy was analyzed based on an evaluation of their sensitivity, specificity, positive and negative predictive values, and Kappa index, resulting in the selection of the Willis technique as the nominal gold standard. Of the 154 samples, 115 (74.

Assessment of laboratory methods used in the diagnosis of congenital toxoplasmosis after maternal treatment with spiramycin in pregnancy.

Background: The different laboratory methods used in the diagnosis of congenital toxoplasmosis have variable sensitivity and specificity. There is no evidence to prove that maternal treatment reduces the risk of fetal infection. The purpose of this study was to assess methods for the confirmation of congenital toxoplasmosis after maternal treatment with spiramycin during pregnancy, and to evaluate the effect of this treatment on clinical manifestations of the disease in newborns (NB).

[Vertical transmission from abortive material and blood with emphasis on Toxoplasma gondii].

Purpose: To analyze the serological, anatomopathological and parasitological results obtained from abortive material in order to detect infections with the risk of vertical transmission, with emphasis on toxoplasmosis.

Methods: A cross-sectional cohort study was conducted in order to determine the prevalence of infectoparasitic diseases. A total of 105 women who suffered spontaneous complete or incomplete abortion participated in the study.

Chagas disease: increased parasitemia during pregnancy detected by hemoculture.

One hundred fifty-two Trypanosoma cruzi seropositive women were submitted to a single hemoculture; 101 were pregnant, and 51 were not pregnant. Seven tubes from each individual were harvested with liver infusion tryptose (LIT) medium and observed monthly until the fifth month. Hemocultures were positive in 50% (76 of 152) of the women.
