Benefit and risk of Tripterygium Glycosides Tablets in treatment of rheumatoid arthritis based on multi-criteria decision-making analysis / 中国中药杂志

Rheumatoid arthritis(RA) has a high disability rate and is highly harmful. It has a long course of treatment and is prone to adverse reactions or events(ADR/ADE). Selection of drugs in particular shall give consideration to both benefits and risk. Tripterygium Glycosides Tablets(TGT) is one of the important drugs for the treatment of RA. It has a remarkable efficacy, but a strong toxicity, which is controversial in clinical use. The study was oriented to patients, and quantitatively evaluated the efficacy and risk of TGT in treatment of RA, providing an intuitive basis for clinical safety and effective application of TGT. A multi-criteria decision-making analysis(MCDA) model of TGT was built in the treatment of RA, and then benefit and risk indicators were weighted by SWING method. Totally 53 random clinical trials(RCT) in accordance with the evaluation criteria were included by Meta-analysis method. The RCT results were merged by Meta-analysis, indicating that compared with the conventional therapy of chemical immunosuppressant(CISD), TGT could improve the curative effect whether it was used alone or in combination with CISD, but it would increase the incidence of reproductive system damage. The combined administration with CISD would also increase the incidence of liver and kidney damages. Treatment outcomes varied according to the different conditions of the combined administration with CISD. Based on MCDA model and clinical results, the benefit value, risk value and benefit-risk value of different doses, courses and combined administration of TGT in the treatment with RA were compared. The results showed that when the benefit and risk of the drug were equally important to the patient, the benefit-risk value of the single administration of TGT was 59, while that of the combined administration of TGT and CISD was 39. Therefore, the benefit-risk value of the single administration of TGT was 100% better than the combined administration. When the combined administration of TGT and CISD is unavoidable, the benefit-risk value of low-dose TGT(0.10-0.99 mg·kg~(-1)·d~(-1)) was 48, while that of high-dose TGT was 36. Therefore, low-dose TGT combined with CISD was more easily accepted by patients. The 2 to 3-month treatment course had a benefit-risk value of 40, while the long treatment course had a benefit-risk value of 38. Based on existing evidences, the single administration of TGT may be better than the combined administration with CISD. If the patients need to combine with CISD to treat RA, low dosage and 2 to 3-month course may be relatively optimal.

RESUMO Com o aumento da demanda e a crise hídrica em muitos países, a gestão de perdas em sistemas de abastecimento de água mostra-se relevante em todos os serviços de água. Esta pesquisa propôs-se a construir um modelo de avaliação de desempenho para apoiar uma empresa de saneamento quanto à gestão de perdas nos sistemas de abastecimento de água que opera. Para tanto, baseou-se na Metodologia Multicritério de Apoio à Decisão - Construtivista (MCDA-C). A construção do modelo seguiu as três fases do MCDA-C: estruturação, avaliação e recomendações. Na fase de estruturação, foram construídos 64 descritores, distribuídos em quatro áreas de preocupação: perdas aparentes, perdas reais, apoio operacional e relacionamento externo. Ao final da fase de avaliação, o status quo do sistema de abastecimento de água estudado foi de 22,51, considerado, pelo decisor, no nível competitivo. Foram elaboradas recomendações de ações para melhorar o desempenho do status quo para aqueles descritores que apresentaram desempenho comprometedor e que foram julgados pelo decisor como merecedores de aperfeiçoamento. As recomendações simuladas em conjunto foram importantes para a melhora no desempenho em todas as áreas de preocupação, resultando no desempenho global de 60,82. Assim, a metodologia MCDA-C mostrou-se coerente para os temas abordados nesta pesquisa e confirmou suas premissas construtivistas em todas as suas fases aqui desenvolvidas: estruturação, avaliação e recomendações.

ABSTRACT Considering the increasing demand and the water crisis in many countries, loss management in water supply systems seems relevant to all water services. This research set out to build a performance evaluation model to support a sanitation company on the loss management in the water supply systems that it operates, based on the Constructivist Multicriteria Decision Aid Approach (MCDA-C). The model construction followed the three phases of MCDA-C: structuring, actions evaluation and recommendations. The structuring phase resulted in 64 descriptors in four families of fundamental points of view: apparent losses, real losses, operational support, and external relations. At the end of the evaluation phase, the status quo of the water supply system studied was 22.51, within the competitive level judged by the decision-maker. Actions recommendations were designed to improve the status quo performance of those descriptors with compromising performance, judged by the decision-maker as relevant to be improved. Recommendations were important for improving performance in all families of fundamental points of view, resulting in the overall performance of 60.82. This way, the MCDA-C methodology proved to be consistent for the topics covered in this research and confirmed its constructivist assumptions in all the stages developed here: structuring, evaluation and recommendations.

Aconitum in treatment of rheumatoid arthritis: benefit-risk assessment / 中国中药杂志

Rheumatoid arthritis (RA) has the characteristics of long course of disease and difficulty in treatment. The conventional therapy may easily induce adverse drug reactions or events (ADR/ADE) due to the long-time medication. Thus, it should be given special attentions to treatment benefit and medication risk of RA patients. Aconitum, a kind of toxic traditional Chinese herbs, is an important complement therapy for RA, with some controversy in clinical application. Coming straight to the practical problem of combined use of traditional Chinese medicines (TCM) and Western medicines (WM), this study conducted quantitative assessment on the benefits and risks of Aconitum using combined with WM or not, which was carried out by the method of multi-criteria decision analysis model. RevMan 5.2 software was used to separately analyze the results of every index of 21 random clinical trials (RCTs) of Aconitum exclusive use in the treatment of RA, and 49 RCTs of Aconitum combined use with WM. The merged results indicated that as compared with the conventional therapy of WM, no matter the exclusive use or the combined use of Aconitum could improve the efficacy and decrease the incidence of ADR/ADEs. Based on the benefit-risk assessment decision tree of RA treatment, Hiview 3 software and Crystal Ball Monte Carlo simulation were used to calculate the benefit value, risk value and benefit-risk value of Aconitum exclusive use and the combined use of Aconitum with WM. The results showed that the combination therapy had significantly better benefits than Aconitum exclusive using, difference value was 15, (95%CI[9.72, 20.25]), but the risk of combined use was higher difference value=23, （95%CI[15.57, 30.55]）. In comprehensive consideration of the benefit and risk, the total benefit-risk value of using Aconitum alone was 58, while that of the combination therapy was 55, and the probability of the former superior to the latter was 81.07%. The study showed that Aconitum was the important therapy to supply RA treatment. In clinical application, the patient's acceptability of benefit and risk need to be considered; if patients cannot bear the risk, the combination use of Aconitum and WM is not recommended.

The clinical features of monochorionic or dichorionic twin pregnancy and the high-risk factors for selective intrauterine growth restriction / 实用医学杂志

Objective To explore the clinical characteristics of monochorionic or dichorionic twin pregnancy and the high-risk factors for selective intrauterine growth restriction.Methods 460 women with twin pregnancy were divided into a monochorionic group and a dichorion group.The related clinical features were compared between the two groups.Logistic regression was used to analyze the high-risk factors for selective intrauterine growth restriction.Results The maternal age,conception way,and mode of delivery differed significantly between the two groups (P ＜ 0.05).There were significant differences in the rates of selective intrauterine growth restriction and preterm premature rupture of membranes (P ＜ 0.05).The neonatal weight (large or small) and the rate of neonatal transfer differed significantly (P ＜ 0.05).Logistic regression showed that gestational age and birth weight were the risk factors.Conclusions The chorionic nature plays an important role in the process and outcomes of maternal pregnancy.Monochorionic pregnancy is a high risk factor for selective intrauterine growth restriction,meaning the major cause of selective intrauterine growth restriction may originate from the placenta,with should be a placenta-derived disease.

Proposição de um modelo de avaliação multicritério da sustentabilidade em instituições públicas / Proposing a multi-criteria evaluation model of sustainability in public institutions

O presente trabalho trata-se de uma pesquisa aplicada com finalidade propositiva, que aborda o tema da avaliação multicritério da sustentabilidade em instituições públicas nas suas três principais dimensões: ambiental, social e econômica (tripé da sustentabilidade). A pesquisa analisou como principal instrumento o programa do governo federal brasileiro denominado Agenda Ambiental na Administração Pública – A3P, incorporando a ele os padrões da Global Reporting Initiative– GRI e do Instituto Ethos. A partir da análise deste instrumento foi proposto um modelo para avaliação da sustentabilidade de instituições públicas que permite converter indicadores qualitativos em quantitativos por meio da utilização da ferramenta multicritério de apoio à decisão (MCDA) Promethee. O modelo proposto estimula a utilização de ferramentas multicritério (MCDA) por gestores públicos nas suas decisões, a fim de buscar o equilíbrio dinâmico organizacional nas esferas ambiental, social e econômica nas instituições públicas.

This study is an applied research with propositioning purpose, which addresses the concept of multi-criteria analysis of sustainability in public institutions in their three main dimensions: environmental, social and economic. This research analyzed as the main instrument, the Brazilian federal government program called by Environmental Agenda in Public Administration - EAPA, incorporating to it the standards from the Global Reporting Initiative - GRI and from the Ethos Institute. As a result of this analysis, it was proposed a model for assessing the sustainability of public institutions that converts qualitative indicators into quantitative ones by using the Promethee multi-criteria decision support tool (MCDA). This proposed model encourages the use of multi-criteria decision tools (MCDA) by public officials in order to balance organizational dynamic in public institutions throughout environmental, social, and economic dimensions.
