Trigger Mechanisms

Background/Purpose: Surgical site infection surveillance to determineincidence is a key infection control activity. Case detection is labour-intensive, therefore most infection control programs use manual or simple electronic mechanisms to “trigger” chart review. However, such “trigger” mechanisms are also labour-intensive, and often of poor specificity. Our objective is to develop a complex trigger mechanism using data from an electronic data warehouse, to improve specificity of surveillance of surgical site infection compared to current trigger mechanisms. Methods: We will derive an electronic trigger tool for cardiac surgical site infection surveillance using a nested case-control design, among a cohort of all patients undergoing coronary artery bypass grafting, cardiac valve repairor replacement, or heart transplant at the University of Ottawa Heart Institute, from July 1 2004 to June 30 2007. We will perform a systematic literature review to identify potential trigger factors to include in the model, then construct the trigger tool by backwards stepwise logistic regression. The best-fit model will be used to calculate the probability of surgical site infection. We will select the threshold probability to use in surveillance by visual inspection of receiver-operator-characteristic curves. The accuracy of this electronic trigger mechanism will be compared to pre-existing manual and simple electronic mechanisms using relative true positive ratios and relative false positive ratios. Results/Conclusions: We have selected 200 cases of surgical site infection and 541 controls from among 3744 procedures performed during the study period. As of the date ofthis abstract we are still undertaking the systematic review.

Trigger Mechanisms

In this paper, there will be analyzed the determinants of the inter-ethnic conflict that occurred in the Fergana Valley in the Kyrgyz city of Osh in June 2010. In such a phenomenon as an inter-ethnic conflict, it is rather difficult to find out a single cause of events; it is rather a set of economic, social, demographic, cultural and historical factors that are in a particular political context. And by the summer of 2010 a political context was formed: as a result of the April coup, there was a change of elites in the state power, which led to the struggle for the redistribution of economic power and resources. And in the conditions of connections of power and economic structures with the criminals, that was clearly manifested in the country on the eve of the conflict, the contradictions became ethnic. Despite the fact that this ethnic conflict was the result of objective contradictions caused by lack of resources (primarily land), low living standards, demographic and social problems, namely the change of political power in the country, instability, the struggle of criminal and mafia structures for power and influence became the trigger mechanisms that produced violence. There are various versions claiming to explain the events of June 2010, as well as to evaluate the actions of official structures during the conflict. Thus, the Uzbek side claimed that the security forces were inactive, ignored the attacks, in turn, the official authorities argued that the conflict was aggravated by unknown, allegedly foreign mercenaries, besides the Kyrgyz side referred to the police’s unwillingness to such events in the first days of the conflict. Therefore, an analysis of the causes of interethnic conflict in Osh will make it possible to identify the main vectors of instability in society, to identify the main actors to which measures of state influence should be directed in order to prevent possible relapses.

Abstract Introduction Heart failure is associated with degradation of cell functions and extracellular matrix proteins, but the trigger mechanisms are uncertain. Our recent evidence shows that active digestive enzymes can leak out of the small intestine into the systemic circulation and cause cell dysfunctions and organ failure. Methods Accordingly, we investigated in morning fasting plasma of heart failure (HF) patients the presence of pancreatic trypsin, a major enzyme responsible for digestion. Results Western analysis shows that trypsin in plasma is significantly elevated in HF compared to matched controls and their concentrations correlate with the cardiac dysfunction biomarker BNP and inflammatory biomarkers CRP and TNF-α. The plasma trypsin levels in HF are accompanied by elevated pancreatic lipase concentrations. The trypsin has a significantly elevated activity as determined by substrate cleavage. Mass spectrometry shows that the number of plasma proteins in the HF patients is similar to controls while the number of peptides was increased about 20% in HF patients. The peptides are derived from extracellular and intracellular protein sources and exhibit cleavage sites by trypsin as well as other degrading proteases (data are available via ProteomeXchange with identifier PXD026332). Connclusions These results provide the first evidence that active digestive enzymes leak into the systemic circulation and may participate in myocardial cell dysfunctions and tissue destruction in HF patients. Conclusions These results provide the first evidence that active digestive enzymes leak into the systemic circulation and may participate in myocardial cell dysfunctions and tissue destruction in HF patients.
