Opis:
If planned improperly, parenteral nutrition may result in a number of severe metabolic complications caused by insufficient or excessive delivery of individual nutrients. One of the most common and the most dangerous complication is parenteral nutrition-associated liver disease (PNALD). Such a complication may also result from using RTU (ready-to-use) bags that are not adjusted adequately to individual patients. The aim of the study was the analysis of prevalence and determining the cause of liver disease in patients who had been receiving parenteral nutrition in primary centres prior to the implementation of home parenteral nutrition in the specialist centre. Material and methods. The study enrolled 146 patients who were referred to the Clinic in the period of 2006-2012 in order to be qualified for home parenteral nutrition. Interview and medical documentation revealed that 100 patients had been receiving parenteral nutrition by means of ready-to-use (RTU) bags in their primary centres. In the remaining 46 patients, such feeding had not been implemented. Upon admission, the following parameters were evaluated: bilirubin, aspartate aminotransferase (AspAT), alanine aminotransferase (AlAT), lactate dehydrogenase (LDH), gamma-glutamyltranspeptidase (GGTP), alkaline phosphatase (AP), triglycerides (TG), cholesterol, protein, albumins, amylase, urea, creatinine and C-reactive protein (CRP). The analysis of the results was conducted with the use of the Student’s T-test. Results. The patients who had been receiving parenteral nutrition manifested significantly increased (p < 0.05) levels of total bilirubin, TG, AlAT, LDH, GGTP, AP and CRP. 23% of patients were diagnosed with jaundice, in 70%, GGTP > 100 i.u. and a half manifested biochemical features of cholestasis. No correlation was observed between the CRP level and results of liver function tests. Conclusions. It was found that there is a correlation between parenteral nutrition with RTU bags and liver disease. The probable cause of liver disease associated with parenteral nutrition received prior to the transfer to the Clinic is excessive administration of lipids. It can be accompanied by excessive administration of glucose. Modification of parenteral nutrition helped to compensate for liver disorders in all patients

Opis:
Drinking fresh water, turning the lights on, travelling by tram, calling our family, or getting a medical treatment are usual activities, but the underlying SCADA (Supervisory Control and Data Acquisition) systems like CIS (Critical Infrastructure Systems), ICS (Industrial Control Systems) or DCS (Distributed Control Systems) were always the target of many types of attacks, endangered the above mentioned simple activities. During the last decades because of the fast spread of the internet based services and the continuous technical development these systems become more vulnerable than ever. Full reconstruction and innovative changes in older SCADA systems has high cost, and it is not always rewarding. Communication protocols as Modbus (1979) serve as a main basis for SCADA systems, so security of Modbus has a major impact of the security of SCADA systems. Our paper raises and answers questions about the security of the Modbus RTU protocol. We focus on the serial Modbus protocol, because in that method we found many unsolved problems, like lack of authentication of the participants, lack of secure channel and so on. The aim of this paper to propose a secure communication alternative for Modbus RTU @ RS485 wire. The main advantage of the proposed method is the coexistence with traditional slaves and bus systems and only software update is necessary.
