The validity and 4-year test-retest reliability of the Brazilian version of the Eating Attitudes Test-26

In a cross-sectional study conducted four years ago to assess the validity of the Brazilian version of the Eating Attitudes Test-26 (EAT-26) for the identification of abnormal eating behaviors in a population of young females in Southern Brazil, 56 women presented abnormal eating behavior as indicated by the EAT-26 and the Edinburgh Bulimic Investigation Test. They were each matched for age and neighborhood to two normal controls (N = 112) and were re-assessed four years later with the two screening questionnaires plus the Composite International Diagnostic Interview (CIDI). The EAT results were then compared to diagnoses originating from the CIDI. To evaluate the temporal stability of the two screening questionnaires, a test-retest design was applied to estimate kappa coefficients for individual items. Given the prevalence of eating disorders of 6.2%, the CIDI psychiatry interview was applied to 161 women. Of these, 0.6% exhibited anorexia nervosa and 5.6%, bulimia nervosa (10 positive cases). The validity coefficients of the EAT were: 40% sensitivity, 84% specificity, and 14% positive predictive value. Cronbach's coefficient was 0.75. For each EAT item, the kappa index was not higher than 0.344 and the correlation coefficient was lower than 0.488. We conclude that the EAT-26 exhibited low validity coefficients for sensitivity and positive predictive value, and showed a poor temporal stability. It is reasonable to assume that these results were not influenced by the low prevalence of eating disorders in the community. Thus, the results cast doubts on the ability of the EAT-26 test to identify cases of abnormal eating behaviors in this population.

Salvaged single-unit cord blood transplantation for 26 patients with hematologic malignancies not in remission

Treatments for patients with hematologic malignancies not in remission are limited, but a few clinical studies have investigated the effects of salvaged unrelated cord blood transplantation (CBT). We retrospectively studied 19 patients with acute leukemia, 5 with myelodysplastic syndrome (MDS with refractory anemia with excess blasts [RAEB]), and 2 with non-Hodgkin's lymphoma who received 1 CBT unit ≤2 loci human leukocyte antigen (HLA)-mismatched after undergoing myeloablative conditioning regimens between July 2005 and July 2014. All of them were in non-remission before transplantation. The infused total nucleated cell (TNC) dose was 4.07 (range 2.76-6.02)×107/kg and that of CD34+ stem cells was 2.08 (range 0.99-8.65)×105/kg. All patients were engrafted with neutrophils that exceeded 0.5×109/L on median day +17 (range 14-37 days) and had platelet counts of >20×109/L on median day +35 (range 17-70 days). Sixteen patients (61.5%) experienced pre-engraftment syndrome (PES), and six (23.1%) patients progressed to acute graft-versus-host disease (GVHD). The cumulative incidence rates of II-IV acute GVHD and chronic GVHD were 50% and 26.9%, respectively. After a median follow-up of 27 months (range 5-74), 14 patients survived and 3 relapsed. The estimated 2-year overall survival (OS), disease-free survival (DFS), and non-relapse mortality (NRM) rates were 50.5%, 40.3%, and 35.2%, respectively. Salvaged CBT might be a promising modality for treating hematologic malignancies, even in patients with a high leukemia burden.

Rendimentos do abate e composição da carne de ema (Rhea americana)

O objetivo deste trabalho foi estudar o desempenho zootécnico da ema (Rhea americana), rendimentos do abate, composição química e análise sensorial da carne. Onze animais foram submetidos a um sistema de confinamento, recebendo ração balanceada à vontade e com acesso a um piquete. Antes do abate as emas permaneceram em jejum hídrico por 12 h, foram pesadas e submetidas ao processamento: insensibilização, sangria, depenagem manual, esfola e evisceração. As emas apresentaram peso vivo médio, no momento do abate, de 19,393 kg, desempenho médio de 529,82 de consumo de ração/dia, 53,20 g de ganho de peso/dia e 9,44 de conversão alimentar. Em relação ao peso de carcaça, mostraram rendimento médio de 63,33% de carne, 5,09% de gordura e 22% de ossos. A composição centesimal média da carne de ema foi de 22,81% de proteína, 1,59% de lipídios, 1,62% de cinzas e de 74,72% de umidade. O conteúdo de colágeno variou de 0,94% a 1,12% e o teor de colesterol foi de 65,44 mg por 100 g de carne. Pela análise sensorial, verificou-se que a carne de ema processada foi bem aceita pelos provadores. Assim, admite-se que a carne de ema pode ser consumida como fonte de proteína animal com baixo teor de lipídios.
