A EXPERIÊNCIA DE HOSPITALIZAÇÃO EXPLICADA PELA PRÓPRIA CRIANÇA

O presente estudo foi realizado com 20 crianças, em idade escolar, internadas em unidades pediátricas. Teve como objetivos identificar: como as crianças expressam a percepção de sua doença e hospitalização; os recursos de 'que elas dispõem para obter conhecimento sobre sua experiência de doença e hospitalização; e seus interesses e preocupações

The impact of parenteral nutrition on the body composition of patients with acute pancreatitis

Background: Nutrition support by the enteral route is now the preferred modality in patients with severe acute pancreatitis. Parenteral nutrition is now required to supplement enteral nutrition when the latter is not able to provide the full nutritional requirement. We report the changes in body composition, plasma proteins, and resting energy expenditure (REE) during 14 days of parenteral nutrition (PN) in patients with acute pancreatitis. Methods: Total body protein (TBP), total body water (TBW), and total body fat (TBF) were measured by neutron activation analysis and tritium dilution before and after PN. Fat-free mass (FFM) was derived as the difference between body weight and TBF. REE was measured by indirect calorimetry. Protein index (PI) was the ratio of measured TBP to TBP, calculated from healthy volunteers. Results: Fifteen patients with acute pancreatitis (11 men, 4 women; median age 56, range 30-80 years) were studied. Thirteen patients had severe acute pancreatitis (Atlanta criteria), and 1 patient died. The gains in body weight (1.05 +/- 0. 77 kg), TBW (0.49 +/- 0.87 kg), TBP (0.20 +/- 0.22 kg), FFM (0.73 +/- 0.92 kg), TBF (0.32 +/- 0.95 kg), and REE (146 +/- 90 kcal/d) after 14 days of PN were not significant. Plasma prealbumin increased by 46.5% (p = .020). When patients (n = 6) with intercurrent sepsis and recent surgery were excluded, there were significant increases in TBP (0.65 +/- 0.17 kg, p = .005) and PI (0.060 +/- 0.011, P = .0006). Conclusions: Body composition is preserved in acute pancreatitis during 14 days of PN. In patients without sepsis or recent surgery, PN is able to significantly increase body protein stores

Progresso da brusone nas folhas e panículas de genótipos de arroz de terras altas Progress of leaf and panicle blast in upland rice genotypes

Foram avaliados dezesseis genótipos de arroz quanto ao seu nível de resistência parcial à brusone (Pyricularia grisea). A reação dos genótipos à doença foi avaliada durante dois anos, em condições de cultivo de terras altas, no município de Capão Bonito, SP. A severidade da doença nas folhas e panículas foi determinada periodicamente, e os dados foram utilizados para traçar a curva de progresso da doença e cálculo da área sob a curva de progresso da doença para cada genótipo (ASCPD). Os resultados evidenciaram que, considerando os dois anos de avaliação, menores valores de ASCPD foram apresentados nas folhas pelas linhagens IAC 1711, IAC 1774 e IAC 1781 e pelas cultivares BRS Bonança e BRS Liderança; nas panículas, pelas linhagens IAC 1738, IAC 1774 e IAC 1781 e pelas cultivares BRS Bonança, BRS Liderança e Carisma.<br>Partial resistance of sixteen rice genotypes to blast (Pyricularia grisea) was evaluated during two years under upland conditions (Capão Bonito, SP). Blast severity on leaves and panicles was periodically determined and the data were used to obtain the disease progress curve for each genotype and to estimate the area under disease progress curve (AUDPC). Smaller AUDPC values were presented, considering leaf blast, by IAC 1711, IAC 1774 and IAC 1781 lines and BRS Bonança and BRS Liderança cultivars; considering panicle blast, by IAC 1738, IAC 1774 and IAC 1781 lines and BRS Bonança, BRS Liderança and Carisma cultivars

Concurrent resistance and aerobic exercise stimulates both myofibrillar and mitochondrial protein synthesis in sedentary middle-aged men

We determined myofibrillar and mitochondrial protein fractional synthesis rates (FSR), intramuscular signaling protein phosphorylation, and mRNA expression responses after isolated bouts of resistance exercise (RE), aerobic exercise (AE), or in combination [termed concurrent exercise (CE)] in sedentary middle-aged men. Eight subjects (age = 53.3 ± 1.8 yr; body mass index = 29.4 ± 1.4 kg·m2) randomly completed 8 × 8 leg extension repetitions at 70% of one repetition-maximum, 40 min of cycling at 55% peak aerobic power output (AE), or (consecutively) 50% of the RE and AE trials (CE). Biopsies were obtained (during a primed, constant infusion of l-[ring-13C6]phenylalanine) while fasted, and at 1 and 4 h following postexercise ingestion of 20 g of protein. All trials increased mitochondrial FSR above fasted rates (RE = 1.3-fold; AE = 1.5; CE = 1.4; P 0.05), while rpS6 (Ser235/236) increased only in RE (10.4) (P < 0.05). CE and AE both resulted in increased peroxisome proliferator receptor-γ coactivator 1-α (PGC1α) expression at 1 h (CE = 2.9; AE = 2.8; P < 0.05) and 4 h (CE = 2.6; AE = 2.4) and PGC1β expression at 4 h (CE = 2.1; AE = 2.6; P < 0.05). These data suggest that CE-induced acute stimulation of myofibrillar and mitochondrial FSR, protein signaling, and mRNA expression are equivalent to either isolate mode (RE or AE). These results occurred without an interference effect on muscle protein subfractional synthesis rates, protein signaling, or mRNA expression
