Screening endoscopy is recommended for early detection of esophageal varices (EVs) in cirrhotic patients with portal hypertension. However, this approach is limited by its invasiveness and cost. The aim of the study was to determine if platelet count can predict the presence of EVs, especially large (grade III, IV) EVs in need of prophylactic therapy, in a cohort of Egyptian patients with liver...
INTRODUCTION We hypothesized a relationship between severity of thoracic aortic atheroma (AA) and prevalence of high-risk coronary anatomy (HRCA). MATERIAL AND METHODS We investigated AA diagnosed by transesophageal echocardiography and HRCA diagnosed by coronary angiography in 187 patients. HRCA was defined as ≥ 50% stenosis of the left main coronary artery or significant 3-vessel coronary a...
We introduce Horizon Decomposition in the context of Dantzig-Wolfe Decomposition, and apply it to the Capacitated Lot-Sizing Problem with Setup Times. We partition the problem horizon in contiguous overlapping intervals and create subproblems identical to the original problem, but of smaller size. The user has the flexibility to regulate the size of the master problem and the subproblem via two...
Background: Assessment of AMH cut-off levels in serum and in follicle fluid (FF) for patients with (group 2, n=34) and without (group1, n= 96) endocrinological risk factors, such as ovarian hyperstimulation syndrome (OHSS) and polycystic ovary syndrome (PCOS), is clinically useful in optimising the treatment protocol. Materials and Methods: AMH was analysed in serum and FF of 130 infertile pati...
Objective: The present this study aimed to determine the proper cut-off points for waist circumference (WC), Waist to height ratio (WHtR) and body mass index (BMI) for early predicting of metabolic syndrome among inactive college students. Materials and Methods: In this cross-sectional study, 126 males (age 20.33±1.71) and 63 females (age 20.36±1.72) with inactive lifestyle parti...
This article tries to analyze the effect of eliminating the electricity subsidy on the intensity of this energy in production industries during 1995-2007 using GMM dynamic panel data method. Having used the cost function with Cobb-Douglas form, it was recognized that there is a negative and significant relationship between electricity intensity and its price. Meanwhile, the increase in the pric...
OBJECTIVE The aim of this study is to investigate the relationship between procalcitonin (PCT) level and the severity of acute cholecystitis. MATERIALS AND METHODS This study included 200 patients diagnosed with acute cholecystitis. To diagnose and assess the severity of acute cholecystitis; physical examination and abdominal ultrasound findings were evaluated and blood samples were taken to ...
OBJECTIVE To determine if electrical impedance spectroscopy (EIS) improves the diagnostic accuracy of colposcopy when used as an adjunct. DESIGN Prospective, comparative, multi-centre clinical study. SETTING Three colposcopy clinics: two in England and one in Ireland. POPULATION Women referred with abnormal cytology. METHODS In phase 1, EIS was assessed against colposcopic impression an...
Branch-price-and-cut has proven to be a powerful method for solving integer programming problems. It combines decomposition techniques with the generation of both columns and valid inequalities and relies on strong bounds to guide the search in the branch-and-bound tree. In this paper, we present how to improve the performance of a branch-price-and-cut method by using the primal-dual interior p...
