谁应该领导IMF？ 002

Bone Mineral Density Reporting Underestimates Fracture Risk in Ontario

21世纪经济报道

每当IMF在等待一位新领导时，批评家们就会抱怨，人们老是嚷嚷着应该任命一位新兴经济体的候选人来担任IMF领导，但是总是停留在嘴上从没实现过。但是，抱怨归抱怨，这不能改变60年来的历史，那就是IMF的总裁由欧洲人担任，而美国领导...

Objective: Analysis of clinical documents such as bone mineral density (BMD) reports is an important component of program evaluation because it can provide insights into the accuracy of assessment of fracture risk communicated to patients and practitioners. Our objective was to compare fracture risk calculations from BMD test reports to those based on the 2010 Canadian guidelines. Methods: We retrieved BMD reports from fragility fracture patients screened through a community hospital fracture clinic participating in Ontario’s Fracture Clinic Screening Program. Fracture risk was determined according to the 2010 Canadian guidelines using age, sex, and T-score at the femoral neck, in addition to three clinical factors. Three researchers classified patients’ fracture risk until consensus was achieved. Results: We retrieved reports for 17 patients from nine different BMD clinics in the Greater Toronto Area. Each patient had a different primary care physician and all BMD tests were conducted after the 2010 Canadian guidelines were published. The fracture risk of 10 patients was misclassified with 9 of the 10 reports underestimating fracture risk. Nine reports acknowledged that the prevalence of a fragility fracture raised the risk category by one level but only four of these reports acknowledged that the patient had, or may have sustained, a fragility fracture. When we raised fracture risk by one level according to these reports, eight patients were still misclassified. Fracture risk in the majority of these patients remained underestimated. Inconsistent classification was found in the majority of cases where reports came from the same clinic. Four reports described risk levels for two different types of risk. Conclusions: More than half of patients received BMD reports which underestimated fracture risk. Bone health management recommendations based on falsely low fracture risk are likely to be sub-optimal.

Journal of Shanghai Jiaotong university(Science) 2000年第1期5卷 321-331页

It is well-known that the local heating/cooling rate implicitly drives the quality and stability of the projection associated with an inverse heat conduction analysis. However, contemporary studies involving inverse heat conduction for heat treatment processes and defense related applications normally use either temperature or strain data. An illustration is presented indicating the merit of using a device capable of either measuring or deducing the heating/cooling rate. Armed with this knowledge certainly suggests that the direct measurement or deduction of the heating/cooling rate can provide a means for developing an alternative and potentially more accurate projection than based on temperature data. A brief theoretical description is offered illustrating that a first-order thermocouple compensation model used in conjunction with an inverse analysis produces a representative prediction of the heating/cooling rate. The presented analysis also offers additional insight into the choice of optimal time-series truncation used by quasi-analytic methods. Using the compensation model, the heating/cooling rate of the desired surface is obtained using the "best" interpretation of the collected thermocouple data. A mathematical formalism is developed and some representative results are presented. Finally, a new mathematical discovery that allows for the time-local temperature errors to be estimated with a high degree of accuracy is briefly elucidated.
