Background: Surgical mortality data are collected routinely in high-income countries, yet virtually no low-or middle-income countries have outcome surveillance in place. The aim was prospectively to collect worldwide mortality data following emergency abdominal surgery, comparing findings across countries with a low, middle or high Human Development Index (HDI).Methods: This was a prospective, multicentre, cohort study. Self-selected hospitals performing emergency surgery submitted prespecified data for consecutive patients from at least one 2-week interval during July to December 2014. Postoperative mortality was analysed by hierarchical multivariable logistic regression.
Cell ConceptA high-dielectric constant material have received increasing attention in view of an application to ULSI DRAMs for keeping a simple cell structure. We demonstrate a new technology with a planar-type single stacked structure utilizing a high-dielectric constant film of Bal -,SrXTi03 (BST). The fabricated memory cell ca acitor shows a low leakage current of 2x10-9Ncm under an applied voltage of 3.3V and a large capacitance of 32fF/um2, which means that the BST film is equivalently as thin as 1.3nm of Si02.

Bullous systemic lupus erythematosus (SLE) is a chronic, widespread, non-scarring, subepidermal blistering eruption associated with autoimmunity to type VII collagen. We describe a patient with Sj ogren's syndrome/lupus erythematosus overlap syndrome who showed transient blistering eruptions over limited skin surface and in oral mucosa. At the time of aggravation, the patient's serum contained IgG autoantibodies that bound to the dermal side of 1 mol/L NaCl-split normal skin, as determined by an indirect immunofluorescence test, and that reacted to type VII collagen, as determined by immunoblotting on dermal extract. Our observations suggest that a chronic, widespread, blistering eruption is not a prerequisite for the diagnosis of bullous SLE, and a mild, transient, blistering eruption could be a manifestation of type I bullous SLE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
