RESUMO: Nos últimos anos, tem sido observado um aumento na incidência de obesidade em gatos, sendo associado a doenças metabólicas e cardiovasculares e a associação dessas alterações pode desencadear o surgimento de síndrome metabólica. Diante disto, o objetivo deste trabalho foi analisar os níveis séricos de glicose, frutosamina, colesterol, triglicerídeos, HDL, LDL, VLDL e ALT dos gatos e identificar uma possível presença de síndrome metabólica nos mesmos, além de avaliar a ocorrência de alterações na pressão arterial. Utilizaram-se 37 gatos, classificados através de ECC e medidas morfométricas em 15 obesos, 12 sobrepesos e 10 controles. Nenhum gato do estudo manifestou síndrome metabólica. Apenas o VLDL obteve diferença estatisticamente significativa (P<0.05) entre os grupos. Concluiu-se que a obesidade pode não estar associada à hipertensão arterial e que se necessita de mais estudos para avaliar as alterações metabólicas em gatos com sobrepeso e obesos.

ABSTRACT: Obesity has been increasing in cats andis associated with metabolic and cardiovascular diseases. The association of these alterations can trigger the onset of metabolic syndrome (MS). Therefore, this study aimed to analyze the serum levels of glucose, fructosamine, cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, very low-density lipoprotein (VLDL), andalanine aminotransferase of cats and to identify the possibility of MS,as well as to evaluate changes in arterial pressure. Thirty-seven cats were classified by ECC and morphometric measurements, namely, 15 obese, 12 overweight, and 10 controls. Nocat manifested MS. Only VLDL had a statistically significant difference (P<0.05) between groups. Therefore, obesity may not be associated with arterial hypertension, and more studies are needed to evaluate the metabolic alterations in overweight and obese cats.

The purpose of this study was to characterize astrovirus in faecal samples collected from children with and without diarrhea in São Paulo, Brazil, grouped into two sets: EPM and HU. Detection and genotyping were carried out using reverse transcription nested polymerase chain reaction (RT-PCR) with specific primers directed towards the genome open reading frame 2 (ORF2). Results for EPM set showed that 66/234 (28.2%) were positive: 28/94 (29.7%) from children with acute diarrhea, 14/45 (31.1%) with persistent diarrhea, and 9/55 (16.3%) from control individuals. No data was available for 15/40 (37.5%) of samples. Mixed infections with other viruses were found in 33 samples. In the HU, 18/187 (9.6%) were positive: 12/158 (7.6%) from individuals with acute diarrhea and 6/29 (20.7%) from control children. Four samples were mixed with other viruses. Out of 66 astrovirus positive EPM samples, 18 (27.2%) were characterized as human astrovirus type-1 (HAstV-1), two (3.0%) as HAstV-2, two (3.0%) as HAstV-3, and three (4.5%) as HAstV-8. Among 18 astrovirus positive HU samples, one (5.5%) was characterized as HAstV-1, six (33.3%) as HAstV-2, and one (5.5%) as HAstV-8. Two HAstV-8 genotyped samples were further confirmed by nucleotide sequencing. Our results shows that astroviruses are circulating in a constant manner in the population, with multiple serotypes, in higher frequency than it was described for other Brazilian regions. For the first time in Sao Paulo, Brazil, it was shown that astroviruses play an important role in children gastroenteritis, as described for most locations where they were detected.
