BACKGROUND Sodium fluoride (NaF) positron emission tomography combined with computer tomography (PET/CT) has shown to be more sensitive than the whole-body bone scan in the detection of skeletal uptake due to metastases in prostate cancer. We aimed to calculate a 3D index for NaF PET/CT and investigate its correlation to the bone scan index (BSI) and overall survival (OS) in a group of patients...
Environmental Sensitivity Indices (ESI) composed of many field-data are essential for monitoring and control systems. At the beginning of the last decade an ESI of the German Wadden Sea was developed for use by the relevant authorities. This ESI was derived by experts semi-manually analysing the extensive field data-set. An algorithm is presented here which emulates human expert-decisions on th...
We present a novel approach for a tool that assists the database administrator in designing an index connguration for a relational database system. A new methodology for collecting usage statistics at run time is developed which lets the optimizer estimate query execution costs for alternative index conngurations. Deening the workload specii-cation required by existing index design tools may be...
S erotonin (5-hydroxytryptamine [5-HT]) mediates vasoconstriction and induces the activation of platelets, which may promote atherosclerosis. Plasma 5-HT concentrations have been reported to be high in diabetic patients (1,2); this may be one of the underlying mechanisms of diabetes complications. The 5-HT2A receptor has been identified in glomerular mesangial cells (3), suggesting involvement ...
An 87yearold man presented with recent intermittent claudication in the thighs and calves. Moreover, he complained of bilateral calf and foot pain at midnight. He was a former smoker and had a significant medical history of hypertension, hyperlipidemia, and depression. On physical examination, we found that his dorsal artery pulse was reduced, and he had an anklebrachial index score of 0.4 in b...
BACKGROUND The prevalence of carotid artery stenosis (CAS) in the general population is not high enough to justify screening programs. This study was done to determine the prevalence of asymptomatic carotid artery stenosis (ACAS) among patients with severe peripheral vascular disease (PVD). METHODS Between March 2005 and February 2006, 54 consecutive patients with severe PVD admitted at a vas...
OBJECTIVES/HYPOTHESIS To verify the reliability and validity of automated scoring and compare it to that of manual scoring for diagnosing obstructive sleep apnea using an Embletta X100 level 2 portable device. STUDY DESIGN Retrospective study. METHODS A total of 116 patients with suspected obstructive sleep apnea who had successfully received portable polysomnography with the Embletta X100 ...
