Trichostrongylus colubriformis affecting sheep phosphorus metabolism and precision feeding as a mitigating strategy / Trichostrongylus colubriformis afetando o metabolismo do fosforo em ovinos e alimentação de precisão como estratégia de mitigação

Abstract This review details the negative effects of Trichostrongylus colubriformis infection in sheep phosphorus metabolism and direct and indirect impacts from high excretion from susceptible animals, as well as the advantages offered by precision feeding as potential strategies to mitigate loss. In sheep infected with T. colubriformis there is a high reduction in P bioavailability, because of depression in the absorptive capacity of this mineral, affecting the absorption and recycling of P to the digestive tract, causing mineral deficiency. Therefore, precision feeding compiles animal genetics information, feeding type and grazing management to control animal feed intake and quantity and quality of manure produced. In this sense, the adoption of precision feeding can provide a better arrangement of the information, making sheep production more economically, socially and environmentally sustainable.

Resumo Essa revisão detalha os efeitos negativos da infecção por Trichostrongylus colubriformis no metabolismo do fósforo de ovinos e os impactos diretos e indiretos da alta excreção em animais susceptíveis, bem como as vantagens oferecidas pela alimentação de precisão como estratégia potencial para mitigar perdas. Em ovinos infectados com T. colubriformis há uma alta redução na biodisponibilidade de P, devido à depressão na capacidade de absorção desse mineral, afetando a absorção e a reciclagem de P no trato digestivo, causando deficiência mineral. Portanto, a alimentação de precisão compila informações de genética animal, tipo de alimentação e manejo da pastagem para controlar o consumo de alimento e a quantidade e qualidade dos dejetos produzidos. Nesse sentido, a adoção da alimentação de precisão pode proporcionar um melhor arranjo das informações, tornando a produção de ovinos mais econômica, social e ambientalmente sustentável.

The mitigation strategy of emergency department overcrowding / 中国实用护理杂志

Objective To investigate the present situation and reasons of emergency department overcrowding, and put forward effective mitigation strategy. Methods By using input-throughput-outputmodel and choosing the method of fishbone diagram analysis, detaily analysis factors of emergency department overcrowding, then implement three- dimensional intervention in hospital, department, personal. Results Patients who stay>48 h in the emergency department(ED) decreased from 11.9％(15225/127941) to 5.3％(7245/136698); patients who stay > 6 h in the Frist Aid Room of ED decreased from 54.6％(3016/5526)to 17.8％(987/5526), both have statistically significant (χ2=3705.04, χ2=1186.32, P<0.01);before the intervention the National ED Overcrowding Study (NEDOCS) index at 0900, 1300, 2100, 0100 was 234.22 ± 62.31, 253.55 ± 59.26, 303.73 ± 160.24, 187.36 ± 25.73; after the intervention the degree of crowdedness of ED at this four points of time was significantly alleviated, NEDOCS index was 193.09 ± 31.87, 187.09 ± 22.65, 187.36 ± 25.73, 154.03 ± 21.56;there were significant differences between the two groups before and after the intervention (t=2.35-4.32, P<0.05). Conclusions To study and discuss the reasons of emergency department overcrowding, it can effectively relieve the happening of emergency department overcrowding through comprehensive intervention measures such as improve the environment, optimize the process, strengthen emergency medical personnel training and management, improve the service level hospital auxiliary support system.

Risk evaluation and mitigation strategy in oncology products / 中国药学杂志

OBJECTIVE: To review and analyze the specificity and dynamic changes in developing the Risk Evaluation and Mitigation Strategy (REMS) in oncology products. METHODS: Based on FDA's requirement for REMS for some high-risk drugs and biologics, the REMS literatures of oncology products were tracked and accessed. The approved and released REMS programs of anti-cancer drugs were summarized and analyzed. RESULTS: REMS is a key tool for FDA to help manage and ensure the safe use of the medications. Though a disproportionate number of drugs with complex REMS are required in patients with cancer, the percentage of the oncology drugs with REMS requirement is not much higher than non-oncology products. This mainly resulted from the specificity of cancer and chemotherapy, in which much collaborative interaction among health care practitioners as well as the emerging target therapy with highly specificity and selectivity may contribute to minimize risk from medications.CONCLUSION: The necessity of developing REMS for an oncology product depends on its properties and the new circumstances in oncology practice.
