Surgical-site infection risk in oncologic digestive surgery

Surgical-site infection (SSI) is the most prevalent type of hospital infection in surgical patients and is associated with an increase in hospital stay, costs and morbidity/lethality. The knowledge of the main risk factors for this type of infection is important for the establishment of prevention measures regarding modifiable risks factors. The objective of the preset study was to assess the occurrence of SSI and study the risk factors in oncologic surgeries of the digestive system at Hospital de Câncer in Barretos, São Paulo, Brazil. Individuals undergoing oncologic surgeries of the digestive system in the period of 08/01/2007 to 08/10/2008 were prospectively followed for 30 days after surgery. Possible risk factors related to the patient and to the surgical procedure were also studied. A total of 210 surgeries were analyzed, with a global SSI incidence of 23.8%. The following variables were independently associated with SSI: time and type of surgery, radiotherapy before surgery and surgeon's years of experience. The risk factors found in this study have been described by other authors and are not amenable to intervention for SSI prevention. Further studies are recommended with the objective of investigating interventions that could reduce the risk for SSI in this type of surgery

Embedded system for monitoring impact magnitude during orange transport

This paper shows the use of a new system (hardware, firmware and software) to assess the negative impact of transportation on postharvest fruit quality. Fruit and vegetable postharvest losses are very high, using this system it is possible to diagnose and implement improvements in transport, thus decreasing mechanical impact. The system has a hardware endowed with a tri-axial accelerometer and a global positioning system (GPS). The firmware of the system is composed of a threshold based detection algorithm that measures acceleration peaks during transport. The system software allows reporting impact magnitude, geographic location and time of the event on a map using a virtual instrument developed in LabVIEW (TM) platform. The main goal of this research was to test this equipment in the transportation of oranges and analyze the number of occurrences when exceeding a determined acceleration threshold. Orange boxes of about 23 kg each were set on a small truck, filling the body and the equipment was positioned evenly in the back and middle. The test was done through repetition and comparison of data taking into account the position of the equipment in the truck body (back and middle) and different types of pavements on a chosen path of 20.5 km divided among unpaved, asphalt and urban avenues -with and without speed bumps and roundabouts. The chi-square test at 5 % was used for the quantitative data analysis. The results show the frequency of repetition of acceleration peaks according to their orientation (X, Y, Z axes and their combinations). For the total route, a difference was observed between the frequencies of threshold violations depending on the location of the boxes. For the chosen route, the unpaved road and urban avenues showed the highest threshold violation for vertical position -axis Z. Box position in the truck and variations in pavement causes a distinctive impact magnitude. The map showing all impact data showed to be an important tool to give support to food traceability, recording critical points and situations that can be changed443133189th Nut and vegetable production engineering symposium2015Mila
