Objective: To evaluate the temporal trend and spatial distribution of gestational and congenital syphilis in the State of Espírito Santo from 2010 to 2019. Materials and methods: This is an ecological time series study with data on gestational and congenital syphilis obtained from the National System of Diseases and Notifications (SINAN) and live births in the Information System on Live Births (SINASC). Incidence rates of gestational and congenital syphilis were calculated, which were grouped according to the IBGE health macro-regions and analyzed in biennia. Results: 9,763 cases of gestational syphilis and 3,912 cases of congenital syphilis were reported. Gestational syphilis rates ranged from 1.46 in 2013 to 31.49 cases per 1,000 live births in 2018, congenital syphilis rates ranged from 0.12 in 2010 to 11.51 cases per 1,000 live births in 2017. The South region had the lowest incidence rates (2.32 cases/1,000 live births for gestational syphilis and 0.54/1,000 live births for congenital syphilis) and the Metropolitan region the highest (37.08 cases/1,000 live births for gestational syphilis and 13.74/1,000 live births for congenital syphilis). Conclusion: The increase in cases of the disease suggests a deficiency in the quality of prenatal care.

Objetivo: Avaliar a tendência temporal e a distribuição espacial da sífilis gestacional e congênita no Estado do Espírito Santo de 2010 a 2019. Materiais e métodos: Trata-se de um estudo ecológico de série temporal com dados sobre sífilis gestacional e congênita obtidos do Sistema Nacional de Agravos e Notificações (SINAN) e de nascidos vivos no Sistema de Informação sobre os Nascidos Vivos (SINASC). Foram calculadas taxas de incidência de sífilis gestacional e congênita, que foram agrupadas conforme as macrorregiões de saúde do IBGE e analisadas em biênios. Resultados: Foram notificados 9.763 casos de sífilis gestacional e 3.912 casos de sífilis congênita. As taxas de sífilis gestacional variaram de 1,46 em 2013 a 31,49 casos por 1.000 nascidos vivos em 2018, as taxas de sífilis congênita, por sua vez, variaram de 0,12 em 2010 a 11,51 casos por 1.000 nascidos vivos em 2017. Quanto às macrorregiões, a região Sul apresentou as menores taxas de incidência (2,32 casos/1.000 nascidos vivos para sífilis gestacional e 0,54/1.000 nascidos vivos para sífilis congênita) e a região Metropolitana as maiores (37,08 casos/1.000 nascidos vivos para sífilis gestacional e 13,74/1.000 nascidos vivos para sífilis congênita). Conclusão: O aumento dos casos da doença sugere deficiência na qualidade do pré-natal.

Effect of silver nanoparticles (AgNP's) from Duddingtonia flagrans on cyathostomins larvae (subfamily: cyathostominae).

The in vitro effect of silver nanoparticles of the Duddingtonia flagrans filtrate enriched with chitin was evaluated on infective larvae of cyathostomins (L3). After biosynthesis, an assay was carried out with two experimental groups in microtubes, for a period of 24 h: G1 (AgNP's-D. flagrans (43.4 µg/mL) + 120 L3) and G2 (distilled water + 120 L3). At the end of this period, AgNP's-D. flagrans (G1) demonstrated an effect on L3 with a 43% reduction (p < 0.01) in relation to G2. Thus, the authors suggest new designs with AgNP's-D. flagrans for the control of cyathostomins.

Nematicidal activity of silver nanoparticles from the fungus Duddingtonia flagrans.

BACKGROUND: Helminth parasites cause morbidity and mortality in both humans and animals. Most anthelmintic drugs used in the treatment of parasitic nematode infections act on target proteins or regulate the electrical activity of neurons and muscles. In this way, it can lead to paralysis, starvation, immune attack, and expulsion of the worm. However, current anthelmintics have some limitations that include a limited spectrum of activity across species and the threat of drug resistance, which highlights the need for new drugs for human and veterinary medicine. PURPOSE: Present study has been conducted to determine the anthelmintic activity of silver nanoparticles (AgNPs) synthesized from the extract of nematophagous fungus, Duddingtonia flagrans, on the infecting larvae of Ancylostoma caninum (L3). METHODS: The nanoparticles were characterized by visual, ultraviolet, Fourier-transform infrared spectroscopy, transmission electron microscopy (TEM) analysis, and X-ray diffraction. The in vitro study was based on experiments to inhibit the motility of infective larvae (L3), and the ultrastructural analysis of the nematode was performed by images obtained by TEM. RESULTS: The XRD studies revealed the crystalline nature of the nanoparticles, and FTIR results implied that AgNPs were successfully synthesized and capped with compounds present in the extract. The results showed that the green synthesis of AgNPs exhibited nematicidal activity, being the only ones capable of penetrating the cuticle of the larvae, causing changes in the tegmentum, and consequently, the death of the nematode. CONCLUSION: The extract of the fungus D. flagrans is able to synthesize AgNP and these have a nematicidal action.
