Complementary medicines and therapies in clinical guidelines on pregnancy care: A systematic review

BackgroundThere is a need for evidence-based guidance on complementary medicines and therapies (CMT) use during pregnancy due to high prevalence of use and lack of guidance on the balance of benefit and harms.AimEvaluate the extent to which current clinical practice guidelines relevant to Australian healthcare professionals make clear and unambiguous recommendations about CMT use in pregnancy, and synthesise these recommendations.MethodsThe search included EMBASE, PubMed, the National Health and Medical Research Council’s Clinical Practice Guidelines Portal, and websites of Australian maternity hospitals and professional/not-for-profit organisations for published guidelines on pregnancy care. Data were synthesised narratively. Guidelines were appraised by two independent reviewers using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument.FindingsA total of 48 guidelines were found, of which 41% provided recommendations that were not limited to routine vitamin and mineral supplementation. There were wide variations in recommendations, particularly for vitamin D and calcium. There was some consensus on recommending ginger and vitamin B6 for nausea and vomiting, and additional supplementation for women with obesity. Guidelines generally scored poorly in the domains of editorial independence and rigour of development.DiscussionThere is a lack of guidance with regard to appropriate CMT use during pregnancy, which may result in less-than-optimal care. Inconsistency between guidelines may lead to variations in care.ConclusionGuidelines should include clear and unambiguous guidance on appropriate CMT use during pregnancy, be based on a structured search of the evidence and informed by stakeholder engagement.

法律行为解释与解释规则

法律行为的解释旨在明晰和充实法律行为的内容,实现意思自治。对于无相对人的法律行为,采用探究表意人的真实意思的解释规则;对于有相对人的法律行为,采用以表示主义为主并兼顾意思主义的解释方法;对于内容不完整的法律行为,采用补充解释的规则,即通过法律任意性规范和推断当事人的意思表示,来维持法律行为的完整性。     

中日农产品贸易的现状与未来

建立在比较优势基础上的中日农产品贸易是一种互利、互补性的贸易,其贸易格局受多种因素决定。随着乌拉圭回合后国际农产品体制改革和中国加入WTO,中日农产品贸易前景乐观,但也存在许多新问题,诸如中日农产品贸易摩擦不断,日本国内贸易保护主义抬头等。对此,中国应以前瞻性的眼光采取相应对策。     

Survival Analysis For A Sequenced Clinical Trial With Covariates

In this paper we discuss the survival analysis for a clinical trial in which treatment categories and general prognostic data are realised at different stages during a patient's survival time. In the light of possible strategies for the parsimonious modelling of such data, a corresponding sequence of illustrative analyses is presented. Detailed results are given for a weighted least squares analysis and these generally agree with those obtained by maximum likelihood.     

福田康夫当政中日关系的发展走向

媒介研究中的科技与文化——对媒介决定论的再思考

在媒介文化研究中存在着两种截然不同的观点：媒介决定论和社会文化选择论。媒介决定论认为新科技带来新的社会文化形式;而社会文化选择论则认为先有社会文化语境的潜在“召唤”,然后才出现相应的科技形式。随着新媒介的出现,媒介决定论似乎占据主流,但是文化选择论对媒介决定论又起到很好的补充作用,它们之间是一种互补关系。新媒介的出现应该是在科技的进步和文化“召唤”的合力作用下产生的。     

Identifiability of distributions under competing risks and complementary risks model

Let X₁,X₂,…,X_p be p random variables with cdf's F₁(x),F₂(x),…,F_p(x)respectively. Let U = min(X₁,X₂,…,X_p) and V = max(X₁,X₂,…,X_p).In this paper we study the problem of uniquely determining and estimating the marginal distributions F₁,F₂,…,F_p given the distribution of U or of V.

First the problem of competing and complementary risks are introduced with examples and the corresponding identification problems are considered when the X₁'s are independently distributed and U(V) is identified, as well as the case when U(V) is not identified. The case when the X₁'s are dependent is considered next. Finally the problem of estimation is considered.
