A number of new biological markers are being studied as predictors of disease or adverse medical events among those who already have a disease. Systematic reviews of this growing literature can help determine whether the available evidence supports use of a new biomarker as a prognostic test that can more accurately place patients into different prognostic groups to improve treatment decisions and the accuracy of outcome predictions. Exemplary reviews of prognostic tests are not widely available, and the methods used to review diagnostic tests do not necessarily address the most important questions about prognostic tests that are used to predict the time-dependent likelihood of future patient outcomes. We provide suggestions for those interested in conducting systematic reviews of a prognostic test. The proposed use of the prognostic test should serve as the framework for a systematic review and to help define the key questions. The outcome probabilities or level of risk and other characteristics of prognostic groups are the most salient statistics for review and perhaps meta-analysis. Reclassification tables can help determine how a prognostic test affects the classification of patients into different prognostic groups, hence their treatment. Review of studies of the association between a potential prognostic test and patient outcomes would have little impact other than to determine whether further development as a prognostic test might be warranted. 相似文献

Benign smooth muscle proliferations are relatively rare in the oral cavity. Most are classified as angioleiomyomas, some as hamartomatous growths and a few as cutaneous-type leiomyomas. We present two cases of benign smooth muscle proliferations in the tongue, provide a review, briefly discuss histogenesis and offer a clinico-pathological differential diagnosis. 相似文献

Alkaptonuria is a rare hereditary metabolic disease of autosomal recessive inheritance, resulting from deficiency of the enzyme homogentisic acid oxidase. The term “alkaptonuria” was first used in 1859 by Boedeker to describe a patient’s urinary reducing compound, and in 1866, Virchow coined the term “ochronosis” due to typical yellow pigmentation. Deposition of this pigment in articular cartilage leads to ochronotic arthropathy, the most incapacitating complication of alkaptonuria. We report a rare case of shoulder ochronotic arthritis, treated with total shoulder arthroplasty, achieving a successful long-term clinical and radiological outcomes. 相似文献

In this paper, we present a computer-aided-diagnosis (CAD) system prototype, named TND (Thyroid Nodule Detector), for the detection of nodular tissue in ultrasound (US) thyroid images and videos acquired during thyroid US examinations. The proposed system incorporates an original methodology that involves a novel algorithm for automatic definition of the boundaries of the thyroid gland, and a novel approach for the extraction of noise resilient image features effectively representing the textural and the echogenic properties of the thyroid tissue. Through extensive experimental evaluation on real thyroid US data, its accuracy in thyroid nodule detection has been estimated to exceed 95%. These results attest to the feasibility of the clinical application of TND, for the provision of a second more objective opinion to the radiologists by exploiting image evidences. 相似文献

Objective: To investigate the relationships between the Controlling Nutritional Status (CONUT) score and ascites fluid lactate dehydrogenase (LDH) level, and prognosis in patients with malignant peritoneal mesothelioma (MPeM).Methods: A total of 125 patients with MPeM were selected for the study using a pathological screening method. Once the diagnosis is established, before the treatment their clinical characteristics and nutritional evaluations were recorded including CONUT score and ascites LDH level. The associations between CONUT, ascites LDH, and other clinicopathological features including body mass index, asbestos exposure, pathological type, and treatment method were analyzed. Prognostic parameters predicting overall survival (OS) were analyzed by Cox regression.Results: High CONUT score, high ascites LDH level were positively associated with poor prognosis in patients with MPeM according to univariate analyses (P?<?0.001, P?<?0.001, respectively), and CONUT score and ascites LDH were independent predictors of a poor prognosis according to multivariate analysis. When the CONUT score is greater than 3 and the ascites LHD is greater than 474?IU/l, it indicates a poor prognosis.Conclusions: CONUT score and ascites LDH are important factors influencing the prognosis of MPeM patients and should thus be considered in clinical applications. 相似文献
