INTRODUCTION AND OBJECTIVE The prognostic value of myocardium deformation measurements in chronic heart failure (CHF) is still poorly addressed. The purpose of this study was to evaluate the correlation of left ventricular (LV) global longitudinal strain (GLS) with clinical and prognostic indicators in patients with CHF and systolic dysfunction. METHODS Ambulatory patients with CHF and LV eje...

OBJECTIVE To compare hemodynamic stress response (HDSR) to ET intubation using Glidescope (GLS) and Flexible fiberoptic laryngoscope (FFB). METHODS This prospective randomized comparative study was conducted at King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia from June 2011 - November 2013. Eighty ASA 1 & 2 patients with normal airway undergoing elective surgical pr...

In this paper, I consider generalized least squares (GLS) estimation in fixed effects panel and multilevel models with autocorrelation. A complication which arises in implementing GLS estimation in these settings is that standard estimators of the covariance parameters necessary for obtaining the feasible GLS estimates will typically be inconsistent due to the inclusion of individual specific f...

T experiment tested two behavioral properties of risky decision making—gain-loss separability (GLS) and coalescing. Cumulative prospect theory (CPT) implies both properties, but the transfer of attention exchange model (TAX) violates both. Original prospect theory satisfies GLS but may or may not satisfy coalescing, depending on whether editing rules are assumed. A configural form of CPT propos...

This study investigates factors affecting tourism demands in Selected OIC Countries for the period of 2004 to 2016. The economic variables used in this study are tourist receipts, GDP per capita, real exchange rate, population, Trade openness and Consumer Price Index. GLS method is applied in the research model in order to investigate the relationship between tourist receipts, GDP per capita, r...

To synthesize studies that use structural equation modeling (SEM), researchers usually use Pearson correlations (univariate r), Fisher z scores (univariate z), or generalized least squares (GLS) to combine the correlation matrices. The pooled correlation matrix is then analyzed by the use of SEM. Questionable inferences may occur for these ad hoc procedures. A 2-stage structural equation modeli...

Recent work has highlighted glutaminase (GLS) as a key player in cancer cell metabolism, providing glutamine-derived carbon and nitrogen to pathways that support proliferation. There is significant interest in targeting GLS for cancer therapy, although the gene is not known to be mutated or amplified in tumors. As a result, identification of tractable markers that predict GLS dependence is need...

Background and Objective: Obesity is one of the problems associated with cardiovascular complications. Patients' heart function improves after sleeve gastrectomy. Global Longitudinal Strain (GLS) is one of the methods used to monitor heart function before and after sleeve gastrectomy.  In this study, we evaluated the echocardiographic parameters pre and post sleeve gastrectomy. Materials and M...

In regression analysis for deriving scaling laws in the context of fusion studies, usually standard regression methods have been applied, of which ordinary least squares (OLS) is the most popular. However, concerns have been raised with respect to several assumptions underlying OLS in its application to fusion data. More sophisticated statistical techniques are available, but they are not widel...

BACKGROUND Left ventricular global longitudinal systolic strain (GLS) has been shown to be superior to ejection fraction in detecting subclinical dysfunction in patients with cancer and predicting mortality in patients with cardiovascular disease. Cancer-related fatigue is common in the later stages of neoplastic malignancies and may be indicative of nonovert heart failure. The aim of this stud...
