Improving access to the international coverage of reports of controlled trials in electronic databases: a search of the Australasian Medical Index

HEALTH INFORMATION & LIBRARIES JOURNAL, Issue 1 2002
Steve McDonald
Introduction: Locating reports of trials from journals not indexed in the major databases presents difficulties to systematic reviewers, and may be a factor in improving the reliability of the reviews. Objectives: To identify and make available reports of controlled trials from the Australasian Medical Index (AMI). To measure the quality of indexing of trials in AMI. Methods: Using a highly sensitive search strategy consisting of methodology indexing and free-text terms, records from AMI were read for reports of controlled trials. Trials meeting the criteria were submitted for inclusion in The Cochrane Controlled Trials Register (CCTR) and assessed for the quality of their indexing. Results: 3621 records were downloaded, of which 512 were identified as reports of controlled trials (317 RCTs; 195 CCTs) and submitted to CCTR. The precision of methodology indexing terms was 60%, but sensitivity just 18%. The quality of indexing of trials was generally poor with only 50 tagged with the RCT/CCT publication type term. 453 reports (88%) were not previously available in CCTR. Conclusions: The large proportion of trials found to be unique to the AMI database increases the pool of studies available to systematic reviewers, and helps ensure CCTR remains the most comprehensive source of trials.

A test strategy for spurious spatial regression, spatial nonstationarity, and spatial cointegration

PAPERS IN REGIONAL SCIENCE, Issue 3 2006
Jørgen Lauridsen
Spatial nonstationarity; spatial cointegration; spurious regression Abstract., A test strategy consisting of a two-step Lagrange Multiplier test is suggested as a device to reveal spatial nonstationarity and spurious spatial regression. It is further illustrated how the test strategy can be used as a diagnostic for presence of a spatial cointegrating relationship between two variables. Using Monte Carlo simulations it is shown that the small-sample behaviour of the test strategy is as desired in these cases. [source]

Do tax-exempt yields adjust slowly to substantial changes in taxable yields?

THE JOURNAL OF FUTURES MARKETS, Issue 8 2008
Donna Dudney
This paper examines the profitability of two futures trading strategies: a municipal bond futures contract strategy and a spread strategy consisting of a municipal bond futures contract and a Treasury bond futures contract. Both strategies are designed to exploit a slow municipal yield adjustment following changes in Treasury yields. We find economically significant profits to both strategies. Average holding period returns per trade for both strategies tend to increase with the magnitude of the Treasury yield change. Profit distributions associated with various Treasury yield change thresholds tend to be positively skewed, and median profits are significantly lower than average profits. The profitability results are consistent with slow municipal yield adjustments. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:763,789, 2008 [source]

Cost-effective mammography screening in Korea: High incidence of breast cancer in young women

CANCER SCIENCE, Issue 6 2009
Soon Young Lee
The epidemiological characteristics of breast cancer in Korean women are different from the characteristics reported in Western women. The highest incidence rate occurs in Korean women in their 40s. The purpose of this study was to determine the most cost-effective screening interval and target age range for Korean women from the perspective of the national healthcare system. A stochastic model was used to simulate breast cancer screenings by varying both the screening intervals and the age ranges. The effectiveness of mammography screening was defined as the probability of detecting breast cancer in the preclinical state and the cost was based on the direct cost of mammography screening and the confirmative tests. The age-specific mean sojourn times and the sensitivity of the mammography were applied in the stochastic model. An optimal cost-effectiveness was determined by the incremental cost-effectiveness ratio and lifetime schedule sensitivity. Sensitivity analyses were undertaken to assess parameter uncertainty. The selected cost-effective strategies were: (1) the current biennial mammography screenings for women who are at least 40 years old; (2) biennial screening for women between the ages of 35 and 75 years; and (3) a combination strategy consisting of biennial screening for women aged between 45 and 54 years, and 3-year interval screening for women aged between 40 and 44 years and 55 and 65 years. Further studies should follow to investigate the effectiveness of mammography screening in women younger than 40 years in Asia as well as in Korea. (Cancer Sci 2009; 100: 1105,1111) [source]

Stereocontrolled Cyclic Nitrone Cycloaddition Strategy for the Synthesis of Pyrrolizidine and Indolizidine Alkaloids

CHEMISTRY - A EUROPEAN JOURNAL, Issue 32 2009
Alberto Brandi Prof.
Abstract The synthesis of polyhydroxylated indolizidines and pyrrolizidines belonging to the class of iminosugars, endowed with a vast and assorted biological activity, can be achieved in a straightforward manner by a general strategy consisting of a highly stereoselective 1,3-dipolar cycloaddition of polyhydroxylated pyrroline- N -oxides followed by simple transformations of the isoxazolidine adducts. The strategy allows the complete control of the relative and absolute stereochemistry of the numerous stereogenic centers decorating these compounds. [source]
