Cardiomiopatia arritmogênica do ventrículo direito em felino: relato de caso / Arrhythmogenic right ventricular cardiomiopathy in a feline: case report

Felino de 3,3kg, fêmea, oito anos de idade, castrada, sem definição racial, foi atendida no Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo (HOVET-USP), com histórico de dispneia, prostração, hiporexia e consequente emagrecimento progressivo, havia uma semana. Foram realizados exames de sangue: hemograma com contagem de plaquetas, função renal, função hepática e dosagens séricas de sódio e potássio, eletrocardiograma (ECG), radiografia torácica, ecoDopplercardiograma, e os resultados dos exames indicaram diagnóstico presuntivo de cardiomiopatia arritmogênica do ventrículo direito. O diagnóstico foi confirmado pela necropsia e pela constatação da presença de tecido fibroadiposo no miocárdio no exame histopatológico, possibilitando, assim, o relato do primeiro caso de cardiomiopatia arritmogênica do ventrículo direito, em gato, no Brasil.(AU)

A female 3.3kg feline, eight years-old, spayed, without racial definition, was submitted to the Veterinary Hospital of the School of Veterinary Medicine and Animal Science, São Paulo University (HOVET-USP) with dyspnea, prostration, hyporexia, and consequent progressive weight loss a week ago. Blood count with platelet count, renal and hepatic profiles, and serum sodium and potassium, chest radiography, electrocardiogram (ECG), and echocardiography were performed and diagnosis of arrhythmogenic right ventricular cardiomyopathy was assumed. The diagnosis was confirmed by necropsy findings and by the presence of fibro-fatty tissue infiltration observed in histopathology, thus featuring the first report of arrhythmogenic right ventricular cardiomyopathy in a cat in Brazil.(AU)

Lateral asymmetry of voluntary attention orienting

We recently demonstrated that automatic attention favors the right side of space and, in the present study, we investigated whether voluntary attention also favors this side. Six reaction time experiments were conducted. In each experiment, 12 new 18-25-year-old male right-handed individuals were tested. In Experiments 1, 2, 3 (a, b) and 4 (a, b), tasks with increasing attentional demands were used. In Experiments 1, 2, 3a, and 4a, attention was oriented to one or both sides by means of a central spatially informative visual cue. A left or right side visual target appeared 100, 300, or 500 ms later. Attentional effects were observed in the four experiments. In Experiments 2, 3a and 4a, these effects were greater when the cue indicated the right side than when it indicated the left side (respectively: 16 ± 10 and 44 ± 6 ms, P = 0.015, for stimulus onset asynchrony of 500 ms in Experiment 2; 38 ± 10 and 70 ± 7 ms, P = 0.011, for Experiment 3a, and 23 ± 11 and 61 ± 10 ms, P = 0.009, for Experiment 4a). In Experiments 3b and 4b, the central cue pointed to both sides and was said to be non-relevant for task performance. In these experiments right and left reaction times did not differ. The most conservative interpretation of the present findings is that voluntary attention orienting favors the right side of space, particularly when a difficult task has to be performed.
