Atletas tenistas adolescentes de alto rendimento: Perfil de consumo e composição corporal

Tennis is an intermittent sport, with movements of high intensity and duration. The present study aimed to assess nutritional status focusing on food intake and body composition of high-performance adolescent athletes. Observational, cross-sectional study with a quantitative approach conducted with 9 athletes from a tennis school in Campo Grande-MS, of both sexes, aged between 10 and 15 years. Dietary research of specific food frequency for athletes was used, comparing with the nutritional recommendations of the International Society for Sports Nutrition for energy and macronutrients and the Institute of Medicine for micronutrients. Anthropometric measurements of weight, height, arm and waist circumferences and skinfolds were performed to determine body fat (%) and fat-free mass (kg). Regarding adequacy, we observed 77.8% of energy intake, in relation to the recommendations, mean intake of carbohydrates of 6.9 g/kg/day, 2.0 g /kg/day of protein and 1.9 g/kg/day of lipids. Calcium intake was below recommendation in 100% of cases. Mean intake above the recommendation was found for zinc, vitamin E and C. Adequate body fat was observed in only 33.3% of tennis players. We concluded that the majority of athletes presented inadequate intake of proteins and micronutrients, which may be reflected in their body composition.O tênis é um esporte intermitente, com movimentos de alta intensidade e curta duração.  O presente estudo objetivou avaliar o estado nutricional focado no consumo alimentar e composição corporal de atletas adolescentes de alto rendimento.

Protein supplement obtained from almonds of bacuri fruit (Attalea phalerata Mart. Ex Spreng.): elaboration, nutritional characterization and sensory acceptability

Bacuri (Attalea phalerata Mart. Ex Spreng.) is a fruit belonging to Palmae family, found in Mato Grosso do Sul - Brazil with great nutritional potential. The objective of the present study was to perform processing, elaboration, nutritional analysis and sensorial acceptability test of protein supplement formulations with bacuri almonds aiming its use by vegetarian public and sportsmen. Bacuri almonds were processed to lyophilized flour of the protein isolate, and then mixed with other ingredients to produce two supplement formulations: F1 containing 70% bacuri lyophilized almond flour, and F2 containing 35% bacuri lyophilized almond flour and 35% commercial supplement. Nutritional composition analysis, amino acid determination and sensory analysis were performed. Both supplements presented high protein content. F1 and F2 were significant different for energy, moisture, ashes, proteins and carbohydrates content. Amino acid profile was satisfactory for methionine, cysteine, phenylalanine and tyrosine for both. Sensory analysis showed acceptability indexes above the minimum limit of 70%, which is considered accepted. Thus, bacuri almond is an alternative ingredient in plant food supplements. However, its isolated use (F1) still needs further testing for sensory acceptability indices improvement

Preventing the acute skin side effects in patients treated with radiotherapy for breast cancer: the use of corneometry in order to evaluate the protective effect of moisturizing creams

BACKGROUND AND PURPOSE: The purpose of this study was to add, to the objective evaluation, an instrumental assessment of the skin damage induced by radiation therapy. MATERIALS AND METHODS: A group of 100 patients affected by breast cancer was recruited in the study over one year. Patients were divided into five groups of 20 patients. For each group it was prescribed a different topical treatment. The following products were used: Betaglucan, sodium hyaluronate (Neoviderm®), Vitis vinifera A. s-I-M.t-O.dij (Ixoderm®), Alga Atlantica plus Ethylbisiminomethylguaicolo and Manganese Cloruro (Radioskin1®) and Metal Esculetina plus Ginko Biloba and Aloe vera (Radioskin 2®); Natural triglycerides-fitosterols (Xderit®); Selectiose plus thermal water of Avene (Trixera+®). All hydrating creams were applied twice a day starting 15 days before and one month after treatment with radiations. Before and during treatment patients underwent weekly skin assessments and corneometry to evaluate the symptoms related to skin toxicity and state of hydration. Evaluation of acute cutaneous toxicity was defined according to the RTOG scale. RESULTS: All patients completed radiotherapy; 72% of patients presented a G1 cutaneous toxicity, 18% developed a G2 cutaneous toxicity, 10% developed a G3 toxicity, no one presented G4 toxicity. The corneometry study confirmed the protective role of effective creams used in radiation therapy of breast cancer and showed its usefulness to identify radiation-induced dermatitis in a very early stage. CONCLUSIONS: The preventive use of topic products reduces the incidence of skin side effects in patients treated with radiotherapy for breast cancer. An instrumental evaluation of skin hydration can help the radiation oncologist to use strategies that prevent the onset of toxicity of high degree. All moisturizing creams used in this study were equally valid in the treatment of skin damage induced by radiotherapy

Colistin and rifampicin compared with colistin alone for the treatment of serious infections due to extensively drug-resistant Acinetobacter baumannii: A multicenter, randomized clinical trial

Background. Extensively drug-resistant (XDR) Acinetobacter baumannii may cause serious infections in critically ill patients. Colistin often remains the only therapeutic option. Addition of rifampicin to colistin may be synergistic in vitro. In this study, we assessed whether the combination of colistin and rifampicin reduced the mortality of XDR A. baumannii infections compared to colistin alone. Methods. This multicenter, parallel, randomized, open-label clinical trial enrolled 210 patients with life-threatening infections due to XDR A. baumannii from intensive care units of 5 tertiary care hospitals. Patients were randomly allocated (1:1) to either colistin alone, 2 MU every 8 hours intravenously, or colistin (as above), plus rifampicin 600 mg every 12 hours intravenously. The primary end point was overall 30-day mortality. Secondary end points were infection-related death, microbiologic eradication, and hospitalization length. Results. Death within 30 days from randomization occurred in 90 (43%) subjects, without difference between treatment arms (P = .95). This was confirmed by multivariable analysis (odds ratio, 0.88 [95% confidence interval, .46-1.69], P = .71). A significant increase of microbiologic eradication rate was observed in the colistin plus rifampicin arm (P = .034). No difference was observed for infection-related death and length of hospitalization. Conclusions. In serious XDR A. baumannii infections, 30-day mortality is not reduced by addition of rifampicin to colistin. These results indicate that, at present, rifampicin should not be routinely combined with colistin in clinical practice. The increased rate of A. baumannii eradication with combination treatment could still imply a clinical benefi

Scintigraphic evaluation of oesophageal transit during radiotherapy to the mediastinum

Background: To quantitatively evaluate radiation-induced impaired oesophageal transit with oesophageal transit scintigraphy and to assess the relationships between acute oesophagitis symptoms and dysmotility.\ud \ud Methods: Between January 1996 and November 1998, 11 patients affected by non-small-cell carcinoma of the lung not directly involving the oesophagus, requiring adjuvant external beam radiotherapy (RT) to the mediastinum were enrolled. Oesophageal transit scans with liquid and semisolid bolus were performed at three pre-defined times: before (T0) and during radiation at 10 Gy (T1) and 30 Gy (T2). Two parameters were obtained for evaluation: 1) mean transit time (MTT); and 2) ratio between peak activity and residual activity at 40 seconds (ER-40s). Acute radiation toxicity was scored according to the joint EORTC-RTOG criteria. Mean values with standard deviation were calculated for all parameters. Analysis of variance (ANOVA) tests and paired t-Tests for all values were performed.\ud \ud Results: An increase in the ER-40s from T0 to T1 or T2 was seen in 9 of 11 patients (82%). The mean ER-40s value for all patients increased from 0.8306 (T0) to 0.8612 (T1) and 0.8658 (T2). These differences were statistically significant (p < 0.05) in two paired t-Tests at T0 versus T2 time: overall mean ER-40s and upright ER-40s (p = 0.041 and p = 0.032, respectively). Seven patients (63%) showed a slight increase in the mean MTT value during irradiation but no statistically significant differences in MTT parameters were found between T0, T1 and T2 (p > 0.05).\ud \ud Conclusion: Using oesophageal scintigraphy we were able to detect early alterations of oesophageal transit during the third week of thoracic RT
