Alternative for Intensification of Beef Production under Grazing

One of the challenges to overcome in order to assure the position occupied by Brazil as one of the most important players in the world beef market is to design sustainable technological alternatives, which will maintain a constant uniform beef supply all year round. This crucial problem could be solved by using more intensively, the alternatives available for pastures management and feed supplement-ation. However, the potential results created by these strategies might be better explored by using the right choice of animals as far as genetic group and weaning weight is concerned. Thus, in order to fulfill this goal it was designed an experiment was designed to evaluate combinations of pastures species (Brachiaria and Panicum), pasture management (feed supplementation and rotational grazing) and animal genetic groups

Tradução e adaptação transcultural para o Brasil do Pediatric Confusion Assessment Method for the Intensive Care Unit para detecção de delirium em unidades de terapia intensiva pediátrica

Objective: To undertake the translation and cross-cultural adaption into Brazilian Portuguese of the Pediatric Confusion Assessment Method for the Intensive Care Unit for the detection of delirium in pediatric intensive care units, including the algorithm and instructions. Methods: A universalist approach for the translation and cross-cultural adaptation of health measurement instruments was used. A group of pediatric critical care specialists assessed conceptual and item equivalences. Semantic equivalence was evaluated by means of a translation from English to Portuguese by two independent translators; reconciliation into a single version; back-translation by a native English speaker; and consensus among six experts with respect to language and content understanding by means of Likert scale responses and the Content Validity Index. Finally, operational equivalence was assessed by applying a pre-test to 30 patients. Results: The back-translation was approved by the original authors. The medians of the expert consensus responses varied between good and excellent, except for the feature “acute onset” of the instructions. Items with a low Content Validity Index for the features “acute onset” and “disorganized thinking” were adapted. In the pre-test, the expression “signal with your head” was modified into “nod your head” for better understanding. No further adjustments were necessary, resulting in the final version for Brazilian Portuguese. Conclusion: The Brazilian version of the Pediatric Confusion Assessment Method for the Intensive Care Unit was generated in agreement with the international recommendations and can be used in Brazil for the diagnosis of delirium in critically ill children 5 years of age or above and with no developmental cognitive disabilities

Candida Infections and Therapeutic Strategies: Mechanisms of Action for Traditional and Alternative Agents

The Candida genus comprises opportunistic fungi that can become pathogenic when the immune system of the host fails. Candida albicans is the most important and prevalent species. Polyenes, fluoropyrimidines, echinocandins, and azoles are used as commercial antifungal agents to treat candidiasis. However, the presence of intrinsic and developed resistance against azole antifungals has been extensively documented among several Candida species. The advent of original and re-emergence of classical fungal diseases have occurred as a consequence of the development of the antifungal resistance phenomenon. In this way, the development of new satisfactory therapy for fungal diseases persists as a major challenge of present-day medicine. The design of original drugs from traditional medicines provides new promises in the modern clinic. The urgent need includes the development of alternative drugs that are more efficient and tolerant than those traditional already in use. The identification of new substances with potential antifungal effect at low concentrations or in combination is also a possibility. The present review briefly examines the infections caused by Candida species and focuses on the mechanisms of action associated with the traditional agents used to treat those infections, as well as the current understanding of the molecular basis of resistance development in these fungal species. In addition, this review describes some of the promising alternative molecules and/or substances that could be used as anticandidal agents, their mechanisms of action, and their use in combination with traditional drugs
