PURPOSE To collect data for the development of a more universally useful logistic regression model to distinguish between a malignant and benign adnexal tumor before surgery. PATIENTS AND METHODS Patients had at least one persistent mass. More than 50 clinical and sonographic end points were defined and recorded for analysis. The outcome measure was the(More)
OBJECTIVES To prospectively assess the diagnostic performance of simple ultrasound rules to predict benignity/malignancy in an adnexal mass and to test the performance of the risk of malignancy index, two logistic regression models, and subjective assessment of ultrasonic findings by an experienced ultrasound examiner in adnexal masses for which the simple(More)
A total of 2142 patients with febrile neutropenia resulting from cancer chemotherapy were registered in two observational studies and followed prospectively in different institutions. There were 499 (23%) patients with bacteraemia who are reviewed here. The relative frequencies of Gram-positive, Gram-negative and polymicrobial bacteraemias were 57%, 34% and(More)
OBJECTIVE To derive simple and clinically useful ultrasound-based rules for discriminating between benign and malignant adnexal masses. METHODS In a multicenter study involving nine centers consecutive patients with persistent adnexal tumors underwent transvaginal gray-scale and Doppler ultrasound examination using a standardized examination technique and(More)
UNLABELLED Clinical variables, like stage and performance status (PS), have predictive and prognostic values in advanced non-small cell lung cancer (NSCLC) patients treated with chemotherapy, not allowing adequate individual prediction. MicroRNA (miRNA) are non-coding RNAs regulating gene expression. In a prospective study, we assessed the predictive value(More)
OBJECTIVES To estimate the ability to discriminate between benign and malignant adnexal masses of different size using: subjective assessment, two International Ovarian Tumor Analysis (IOTA) logistic regression models (LR1 and LR2), the IOTA simple rules and the risk of malignancy index (RMI). METHODS We used a multicenter IOTA database of 2445 patients(More)
In this study, the effect of insertion speed on long-term tissue response and insertion mechanics was investigated. A dummy silicon parylene-coated probe was used in this context and implanted in the rat brain at 10 μm/s (n = 6) or 100 μm/s (n = 6) to a depth of 9 mm. The insertion mechanics were assessed by the dimpling distance, and the force at the point(More)
PURPOSE Several symptoms are described in obstructive sleep apnea (OSA), including excessive daytime sleepiness, depressive mood and neurocognitive dysfunction. However, few studies examined the relationship between objective physical activity, quality of life and sleep parameters. The purpose of this study was to determine sleep parameters (evaluated by(More)
Understanding the mechanical interactions between implants and the surrounding tissue is known to have an important role for improving the bio-compatibility of such devices. Using a recently developed model, a particular micro-machined neural implant design aiming the reduction of insertion forces dependence on the insertion speed was optimized.(More)
The concordance between the change in the Mean Arterial Blood Pressure (MABP) and the Cerebral Blood Flow (CBF) is studied using the Correlation, Coherence and Partial Coherence methods in order to detect Impaired Cerebral Autoregulation in Neonates. The presence of impaired autoregulation is assessed by the use of the Critical Percentage of Recording Time(More)
