Espécies de cigarrinhas (Hemiptera, Cicadellidae, Cicadellinae) em pomares de citros da região de Bebedouro, SP, com descrição de uma espécie nova de Acrogonia Stål

Sharpshooter leafhoppers (Hemiptera, Cicadellidae, Cicadellinae) in citrus groves of the area of Bebedouro, SP, with description of a new species of Acrogonia Stål. Sixteen species of Cicadellidae, subfamily Cicadellinae, were collected and identified: 11 of the tribe Cicadellini and five of the tribe Proconiini. The ten most common species, together with a new species, are characterized based on external morphology and male genitalia: Acrogonia citrina Marucci & Cavichioli sp. nov.; Bucephalogonia xanthophis (Berg, 1879); Dilobopterus costalimai Young, 1977; Ferrariana trivittata (Signoret, 1854); Hortensia similis (Walker, 1851); Macugonalia cavifrons (Stål, 1862); M. leucomelas (Walker, 1851); Oncometopia facialis (Signoret, 1854); Plesiommata corniculata Young, 1977 and P. mollicella (Fowler, 1900). The leafhopper samples were collected in citrus groves and in adjacent habitats (woods, swamp, cultivable plain, spontaneous vegetation of the grove, coffee crop and sugarcane) at the counties of Bebedouro and Monte Azul Paulista and in the district of Turvínia. The collecting methods were: insect net, yellow sticky cards, portable suction trap and Malaise trap. Identification keys were elaborated for the 16 species. There is a great diversity of Cicadellinae species in the citric groves. In the three areas sampled, it was collected a larger number of species of the tribe Cicadellini than of the tribe Proconiini. In the Bebedouro area, the vector species of Xylella fastidiosa, A. citrina sp. nov., B. xanthophis, D. costalimai and O. facialis, were collected in the citrus groves and in all adjacent habitats.

Effects of metformin on the glycemic control, lipid profile, and arterial blood pressure of type 2 diabetic patients with metabolic syndrome already on insulin

Fifty-seven type 2 diabetic patients with metabolic syndrome and on insulin were assessed by a paired analysis before and 6 months after addition of metformin as combination therapy to evaluate the impact of the association on glycemic control, blood pressure, and lipid profile. This was a historical cohort study in which the files of type 2 diabetic patients with metabolic syndrome on insulin were reviewed. The body mass index (BMI), waist circumference, lipid profile, A1C level, fasting blood glucose level, daily dose of NPH insulin, systolic blood pressure, and diastolic blood pressure were assessed in each patient before the start of metformin and 6 months after the initiation of combination therapy. Glycemic control significantly improved (P < 0.001) after the addition of metformin (1404.4 ± 565.5 mg/day), with 14% of the 57 patients reaching A1C levels up to 7%, and 53% reaching values up to 8%. There was a statistically significant reduction (P < 0.05) of total cholesterol (229.0 ± 29.5 to 214.2 ± 25.0 mg/dL), BMI (30.7 ± 5.4 to 29.0 ± 4.0 kg/m²), waist circumference (124.6 ± 11.7 to 117.3 ± 9.3 cm), and daily necessity of insulin. The reduction of total cholesterol occurred independently of the reductions of A1C (9.65 ± 1.03 to 8.18 ± 1.01%) and BMI and the reduction of BMI and WC did not interfere with the improvement of A1C. In conclusion, our study showed the efficacy of the administration of metformin and insulin simultaneously without negative effects. No changes were detected in HDL-cholesterol or blood pressure.
