The regulatory framework for access to medical cannabis has been established in Canada since 2001, with the number of patients seeking access growing substantially over the years. With the novel enactment of the Cannabis Act in October 2018, Canada now maintains two distinct mechanisms for accessing cannabis - one for medical cannabis and the other for non-medical cannabis. With two regulatory access mechanisms in place, questions have arisen in the country as to the necessity of maintaining regulatory separation and the integrity of the medical access framework. A single framework would remove the gate-keeping function that the medical profession currently holds, streamlining processes and simplifying the current regulatory landscape. This approach has been advocated for by the Canadian Medical Association, despite objections from multiple stakeholders. Critical questions arise should the medical access framework be dissolved into a single, non medical-based regulatory framework. Insurance coverage, control mechanisms, market incentives, and patient obligations represent some examples of these issues. This paper will expand upon these considerations and highlight why maintaining two separate access mechanismss best serves the Canadian public. As medicinal cannabis continues to be liberated in international jurisdictions, this paper can help to illuminate the current status of medical cannabis in Canada, and provide insights to those from other countries on our current approach and domestic challenges.  相似文献

Conclusion  We are morally obligated to select therapies which are maximally beneficial for patients. Promoting or discouraging the use of a particular treatment modality, such as BCT, should never be a consideration. To meet this goal, our society must establish guidelines as a part of comprehensive policy. The specialist system, launched under the auspices of the specialist system committee, will hopefully lead to further development of the Japanese Breast Cancer Society.  相似文献

Computerized analysis of lesions in US images of the breast   总被引:1,自引:0,他引:1  
RATIONALE AND OBJECTIVES: Breast sonography is not routinely used to distinguish benign from malignant solid masses because of considerable overlap in their sonographic appearances. The purpose of this study was to investigate the computerized analyses of breast lesions in ultrasonographic (US) images in order to ultimately aid in the task of discriminating between malignant and benign lesions. MATERIALS AND METHODS: Features related to lesion margin, shape, homogeneity (texture), and posterior acoustic attenuation pattern in US images of the breast were extracted and calculated. The study database contained 184 digitized US images from 58 patients with 78 lesions. Benign lesions were confirmed at biopsy or cyst aspiration or with image interpretation alone; malignant lesions were confirmed at biopsy. Performance of the various individual features and output from linear discriminant analysis in distinguishing benign from malignant lesions was studied by using receiver operating characteristic (ROC) analysis. RESULTS: At ROC analysis, the feature characterizing the margin yielded Az values (area under the ROC curve) of 0.85 and 0.75 in distinguishing between benign and malignant lesions for the entire database and for an "equivocal" database, respectively. The equivocal database contained lesions that had been proved to be benign or malignant at cyst aspiration or biopsy. Linear discriminant analysis round-robin runs yielded Az values of 0.94 and 0.87 in distinguishing benign from malignant lesions for the entire database and for the equivocal database, respectively. CONCLUSION: Computerized analysis of US images has the potential to increase the specificity of breast sonography.  相似文献
