NAFLD includes a wide spectrum of liver conditions ranging from simple steatosis to nonalcoholic steatohepatitis and advanced hepatic fibrosis. NAFLD has been recognized as a hepatic manifestation of metabolic syndrome linked with insulin resistance. NAFLD should be considered not only a liver specific disease but also an early mediator of systemic diseases. Therefore, NAFLD is usually associated with cardiovascular disease, chronic kidney disease, type 2 diabetes, obesity, and dyslipidemia. NAFLD is highly prevalent in the general population and is associated with increased cardiovascular morbidity and mortality. The underlying mechanisms and pathogenesis of NAFLD with regard to other medical disorders are not yet fully understood. This review focuses on pathogenesis of NAFLD and its relation with other systemic diseases.展开更多

However, the post-infectious immune dysregulation may result in the Multisystem Inflammatory Syndrome in Children (MIS-C). The most common presentations of MIS are fever, gastrointestinal (diarrhea, vomiting, abdominal pain), cardiovascular, mucocutaneous (rash, mucus membrane changes, conjunctival injection), respiratory (including sore throat), headache, limb and periorbital edema, and elevated inflammation markers. Some clinical and laboratory features of MIS-C are similar to other systemic diseases of childhood as Kawasaki disease and Toxic Shock Syndrome. Here are reported three cases in children with MIS-C, Kawasaki disease and Toxic Shock Syndrome to highlight the similarities and differences of these diseases.展开更多

A fleet of independently operating systems and a single maintenance unit axe considered. It is the objective in this paper to increase overall performance or workload respectively by avoiding delay due to busy maintenance units. This is achieved by concerted and coordinated derating of individual system performance, which increases reliability. Quantification is carried out by way of a convolution-based approach. The approach is tailored to fleets of ships, aeroplanes, spacecraft, and vehicles (trains, trams, buses, cars, trucks, etc.) - Finally, the effectiveness of derating is validated using different criteria. The RAS concept makes sense if average system output loss due to lowered performance level (yielding longer time to failure) is smaller than average loss due to waiting for maintenance in a non-adaptive case.展开更多

Specifically, food-insecure students are more likely to report a lower grade point average than their food secure counterparts. Since the Great Recession, more attention has been given to the topic of hunger and food insecurity among college students;however, the literature still lacks a comprehensive examination of various issues facing today’s college students. Using a multi-systems life course (MSLC) perspective, this paper provides a conceptual explanation of the lived experience of college students by offering a better understanding of the unique challenges faced by this population. Findings from this study will assist researchers, practitioners, and university administrators in their efforts to address hunger among this population.展开更多
