Securing China's rice harvest: unveiling dominant factors in production using multi-source data and hybrid machine learning models.

Ensuring the security of China's rice harvest is imperative for sustainable food production. The existing study addresses a critical need by employing a comprehensive approach that integrates multi-source data, including climate, remote sensing, soil properties and agricultural statistics from 2000 to 2017. The research evaluates six artificial intelligence (AI) models including machine learning (ML), deep learning (DL) models and their hybridization to predict rice production across China, particularly focusing on the main rice cultivation areas.

Soil erosion assessment in the Blue Nile Basin driven by a novel RUSLE-GEE framework.

Assessment of soil loss and understanding its major drivers are essential to implement targeted management interventions. We have proposed and developed a Revised Universal Soil Loss Equation framework fully implemented in the Google Earth Engine cloud platform (RUSLE-GEE) for high spatial resolution (90 m) soil erosion assessment. Using RUSLE-GEE, we analyzed the soil loss rate for different erosion levels, land cover types, and slopes in the Blue Nile Basin.

Background And Aim: Extrahepatic portal vein obstruction (EHPVO) is an important cause of portal hypertension in children. The aim of this study was to describe the clinical presentation, possible risk factors, upper gastrointestinal endoscopic findings, and treatment modalities of children with EHPVO.

Methods: After ethical approval of our study protocol by our institution review board, we analyzed available data from medical records of patients with EHPVO presenting to the Pediatric Hepatology Unit, Cairo University Pediatric Hospital, Egypt, for a period of 15 years from January 1996 to December 2010.

Hereditary tyrosinemia type 1 from a single center in Egypt: clinical study of 22 cases.

Background: Hereditary tyrosinemia type 1 (HT1) is an increasingly recognized inborn error of metabolism among Egyptian children. This study was undertaken to define the presenting clinical, biochemical and imaging features and outcome of 2-(2-motrp-4-trifluoromethylbenzoyl)-1, 3-cyclohexanedione (NTBC) therapy and liver transplantation in a cohort of Egyptian children diagnosed with HT1.

Methods: The study was carried out at the Pediatric Hepatology Unit at Cairo University Children's Hospital.

Study of predictive value of pediatric risk of mortality (PRISM) score in children with end stage liver disease and fulminant hepatic failure.

Objective: To evaluate the use of the PRISM score as a predictor of outcome in patients with end stage liver disease (ESLD) and fulminant hepatic failure (FHF).

Methods: The present study included 30 patients with ESLD and FHF, with ages ranging from 2 to 108 months, who were admitted to the Emergency room (ER) and the Pediatric Hepatology Unit at Cairo University Children's Hospital (tertiary referral hospital) over a six-month-period from May through October 2008. Survivors were followed up for 6 months.

Noninvasive assessment of hepatic fibrosis and necroinflammatory activity in Egyptian children with chronic hepatitis C virus infection using FibroTest and ActiTest.

Background: Hepatitis C virus (HCV) is a major cause of chronic hepatitis and hepatic fibrosis. Liver biopsy, because of its limitations and risks, might be considered an imperfect gold standard for assessing the severity of chronic liver diseases. In this study, we aimed to prospectively validate FibroTest (FT) and ActiTest (AT) as noninvasive serum biochemical markers for assessment of the degree of hepatic fibrosis and necroinflammatory activity respectively, in pediatric patients with chronic HCV infection and compare them to liver biopsy.

(99m)Technetium-macroaggregated albumin perfusion lung scan versus contrast enhanced echocardiography in the diagnosis of the hepatopulmonary syndrome in children with chronic liver disease.

Background And Aims: The hepatopulmonary syndrome (HPS) is a triad of advanced chronic liver disease (CLD), arterial hypoxemia and intrapulmonary arteriovenous shunting in the absence of a primary cardiopulmonary disease. HPS has been more frequently reported in adults than in children with no data on its prevalence in children with CLD. The aim of this study was to detect the prevalence of the HPS in a cohort of children with CLD because of chronic hepatitis B and/or C virus infection, schistosomiasis as well as inborn metabolic errors.
