The link between affect, defined as the capacity for sentimental arousal on the part of a message, and virality, defined as the probability that it be sent along, is of significant theoretical and practical importance, e.g. for viral marketing. A quantitative study of emailing of articles from the NY Times (Berger and Milkman, 2010) finds a strong link(More)
OBJECTIVE To compare prognostic results in patients with gastric stump cancer (GSC) versus those with primary gastric cancer (PGC). SUMMARY BACKGROUND DATA Gastric stump carcinomas have often been described as having low resectability rates and a poor prognosis. METHODS Results of surgical treatment of 50 patients with GSC were compared with that of 516(More)
Reports from a United States cohort of chronic hemodialysis patients suggested that weight loss, a decline in pre-dialysis systolic blood pressure, and decreased serum albumin may precede death. However, no comparative studies have been reported in such patients from other countries. Here we analyzed dynamic changes in these parameters in hemodialysis(More)
BACKGROUND AND OBJECTIVES High body mass index appears protective in hemodialysis patients, but uncertainty prevails regarding which components of body composition, fat or lean body mass, are primarily associated with survival. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Data between April 2006 and December 2012 were extracted from the Fresenius Medical(More)
BACKGROUND Systematic collection and analysis of global hemodialysis patient data may help to improve patient outcomes. METHODS The MONitoring Dialysis Outcomes (MONDO) initiative comprises data from eight dialysis providers worldwide. Data are combined into one repository. Extensive procedures are employed to merge data across countries and providers. (More)
BACKGROUND/AIMS Dialysis providers frequently collect detailed longitudinal and standardized patient data, providing valuable registries of routine care. However, even large organizations are restricted to certain regions, limiting their ability to separate effects of local practice from the pathophysiology shared by most dialysis patients. To overcome this(More)
BACKGROUND/AIM The neutrophil-to-lymphocyte ratio (NLR), defined as the neutrophil count divided by lymphocyte count, is an inexpensive and readily available parameter, which may serve as a surrogate for inflammation markers, such as C-reactive protein (CRP). The aim of this study was to determine the utility of NLR in the prediction of elevated CRP levels(More)
We present an online service with real-time monitoring of Wikipedia pages for companies and detects sentiment with respect to the edits, the companies and editors. It monitors the IRC stream, detects company-related articles using a small hand-built list and performs sentiment analysis using a sentiment-annotated word list. The system generates a report(More)
In contrast to telesurgery, telepresence involves only the audiovisual dialogue between the local surgeon and a remote expert; the latter, however, is able to actively monitor the operation by giving his judgement and recommendations. Under clinical conditions, telepresence may have the potential to facilitate intraoperative consultation of remote experts(More)
BACKGROUND Commencing hemodialysis (HD) using a catheter is associated with a higher risk of adverse outcomes, and early conversion from central-venous catheter (CVC) to arteriovenous fistula/graft (non-CVC) improves outcomes. We investigated CVC prevalence and conversion, and their effects on outcomes during the first year of HD in a multinational cohort(More)
