Short-term electric load forecasting (STLF) is an essential tool for power generation planning, transmission dispatching, and day-to-day utility operations. A number of techniques are used and reported in the literature to build an accurate forecasting model. Out of them Artificial Neural Networks (ANN) are proven most promising technique for STLF model(More)
OBJECTIVE This article outlines the role of FDG PET/CT in patients with cervical carcinoma for evaluating tumor extent, assessing treatment response, and detecting disease recurrence. CONCLUSION There is increasing evidence that FDG PET/CT has a role in the primary evaluation of cervical carcinoma-in particular, for evaluating lymph node status and(More)
Single-photon emission-computed tomography (SPECT) may potentially contribute to the diagnostic work up of patients with neurodegenerative dementia. This systematic review aims to establish the diagnostic utility of 99mTc-hexamethylpropyleneamine (99mTc-HMPAO) and 99mTc-ethylcysteine dimer SPECT in distinguishing between Alzheimer’s disease (AD) and(More)
BACKGROUND Amyloid imaging using fluorine 18-labeled tracers florbetapir, florbetaben, and flutemetamol has recently been reported in Alzheimer's disease (AD). METHODS We systematically searched MEDLINE and EMBASE for relevant studies published from January 1980 to March 2014. Studies comparing imaging findings in AD and normal controls (NCs) were pooled(More)
BACKGROUND Anecdotal evidence suggests variation in intubation decisions for chronic obstructive pulmonary disease (COPD) patients with respiratory failure, but little is known about the extent of or reasons for this variability. AIM To describe clinician decision-making for patients with exacerbations of COPD considered for intubation. DESIGN Telephone(More)
OBJECTIVE Pulse pressure (PP), a strong predictor of cardiovascular events in type 2 diabetes, is a composite measure affected by several hemodynamic factors. Little is known about the hemodynamic determinants of central PP in type 2 diabetes or whether abnormalities in central pulsatile hemodynamics are already present in individuals with impaired fasting(More)
OBJECTIVES Carotid intima-media thickness (cIMT) is an independent predictor of cardiovascular risk. Furthermore, ethnicity and gender-specific normative data are required to assess cIMT, which are not available for Andean-Hispanics. In addition, data regarding correlates of subclinical atherosclerosis in ethnic population are needed. METHODS We studied(More)
BACKGROUND/AIMS Patients with early-onset dementia (EOD) often present atypically, making an accurate diagnosis difficult. Single-photon emission-computed tomography (SPECT) provides an indirect measure of cerebral metabolic activity and can help to differentiate between dementia subtypes. This study aims to investigate the clinical utility of SPECT imaging(More)
AIMS To relate late lumen loss (LLL) after drug-eluting stent (DES) implantation to angiographic (BAR) and target vessel revascularization (TVR) in randomized clinical trials of DES. METHODS AND RESULTS We reviewed all clinical trials comparing different DES and having protocol-driven angiographic follow-up. We combined the data in a meta-regression(More)
