    Required in small amounts, micronutrients play a key role for adequate plant development, which can be supplied by synthetic or organic fertilizers, such as biofertilizers. Thus, an experiment was conducted between July 2014 and August 2015, in the experimental area of the Federal University of the São Francisco Valley, Petrolina-PE, Brazil, to evaluate the micronutrient leaf concentrations of Paluma guava as a function of fertigation with bovine biofertilizer and Nitrogen fertilization. The experimental design was a randomized complete block design (5 x 2) referring to the concentrations of bovine biofertilizer (0, 2.5, 5.0, 7.5 and 10%) and N-fertilizing (50% and 100% of N dose following plant demand), with four replicates and five plants per plot. Only the leaf Mn concentrations are affected by bovine biofertilizer in guava trees fertigated with 100% of recommended N. Leaf concentrations of all the micronutrients (Mn, B, Fe and Zn) are not influenced by nitrogen fertigation. The biofertilizer is efficient in providing Fe.Demandados em pequenas quantidades, os micronutrientes exercem papel fundamental para o desenvolvimento adequado das plantas e podem ser fornecidos por insumos sintéticos ou orgânicos, como os biofertilizantes. Dessa forma, um experimento foi conduzido entre julho de 2014 e agosto de 2015, na área experimental da Universidade Federal do Vale do São Francisco, Petrolina-PE, para avaliar os teores foliares de micronutrientes em goiabeira Paluma em função de fertirrigação com biofertilizante bovino e adubação nitrogenada. O delineamento experimental foi em blocos casualizados em esquema fatorial (5 x 2) referentes às concentrações de biofertilizante bovino (0, 2,5, 5,0, 7,5 e 10%) e adubação mineral com nitrogênio (50% e 100% do recomendado segundo a demanda da cultura), com quatro repetições e cinco plantas por parcela. Apenas os teores foliares de Mn são afetados pelo biofertilizante bovino em goiabeiras fertirrigadas com 100% de N. Os teores foliares de todos os micronutrientes (Mn, B, Fe e Zn) não são influenciados pela fertirrigação nitrogenada. O biofertilizante é eficiente no fornecimento de Fe

    Objective: To evaluate the efficacy of multiple doses of tranexamic acid (TXA) in blood loss in patients undergoing total knee arthroplasty (TKA). Methods: Seven patients of both genders over 50 years old undergoingTKA, who received 15 mg/kg intravenous (IV) TXA 30 minutes before the surgical incision and another 3 doses thereafter were included in this report. Blood loss analysis included blood loss at the drain, hemoglobin loss, and estimated blood loss. Statistical analysis was performed. Results: There was a significant hemoglobin drop after 48 hours, compared to preoperative. Mean blood loss assessed by drain was 20.0 ± 25.17 mL after 24 h. Estimated blood loss was higher after 48 hours compared to 24 hours. No complications were reported in this sample, and no patient received transfusions. Conclusion: The use of TXA in multiple doses did not prevent the drop in postoperative hemoglobin levels and did not correlate with increased complications
