Assessment of hand hygiene compliance after hand hygiene education among health care workers in Cambodia

2016-05Health care-associated infection (HCAI) is the most frequent adverse event for hospitalized patients. Hand hygiene is a simple and effective solution to protect patients from HCAI. This study aimed to introduce hand hygiene to health care workers based on the World Health Organization guideline for reducing HCAI in Cambodia and to assess their behavioral patterns on hand hygiene. All health care workers at Kampong Cham provincial hospital had lectures and practice on hand hygiene in January 2012. The surveys for hand hygiene compliance (HHC) were performed after 6 months, 1 year and 2 years, respectively. The number of surgical site infections (SSI) was counted in 2011 and 2014. Our analysis used the data of 58 workers, who were observed at all three points, although 139 workers were observed during the study period. The average of HHC at 6 months, 1 year and 2 years were 62.37%, 85.76% and 80.36%, respectively. The improved group (HHC 2 years/1 year≧1) had 32 workers, whereas the worsened group (HHC 2 years/1 year<1) had 26. There was a significant difference in departments of the two groups (P=0.011) but not in sex, age or occupations. The improved group had more workers of General (31.2% vs. 19.2%), Surgical (25.0% vs. 11.5%) and Infection (21.9% vs. 11.5%) categories compared to the worsened group. The incidence of SSI was improved from 32.26% in 2011 to 0.97% in 2014. Our results suggest that the education and the survey on hand hygiene are effective for reducing HCAI in Cambodia.departmental bulletin pape

Computer Simulation of Axis-Encircling Beams Generated by an Electron Gun with a Permanent Magnet System

Results from computer aided design of a novel electron gun generating axis-encircling beams are presented and discussed. Numerical experiments were performed by the new version of the software package GUN-MIG named GUN-MIG/CUSP. It is based on a self-consistent relativistic model and is developed as a problem oriented tool for analysis of electron-optical systems with magnetron injection guns (MIG) and electron guns with field reversal (cusp guns), forming axis-encircling beams. As a result of the simulations an electron-optical design of a novel electron gun with permanent magnet system was accomplished. The gun is expected to form high quality beams with small velocity spread and beam ripple. Parameters of the generated beams are appropriate for a prospective weakly relativistic high harmonic large orbit gyrotron (LOG). The development of such device is in progress now at the Research Center for Development of Far-Infrared Region (FIR Center) at Fukui University.othe

Promoter/repressor system of Lactobacillus plantarum phage øg1e: characterization of the promoters pR49–pR–pL and overproduction of the Cro-like protein Cng in Escherichia coli

The Lactobacillus plantarum phage øg1e (42 259 bp) has two repressor-like genes cng and cpg oriented oppositely, accompanied by three potential promoters pR, pL and pR49, and seven operator-like sequences (GATAC-boxes) (Kodaira et al., 1997). In this study, the øg1e putative promoters were introduced into the Escherichia coli promoter-detecting plasmid pKK232-8. In E. coli CK111, pR (pKPR1), pL (pKPL1) and pR49 (pKPR49) exhibited distinct CAT activities. When pKPR1 or pKPL1 was coexistent with a compatible plasmid pACYC184 carrying pR-cng (pA4PRCN1), the CAT activity was decreased significantly. On the other hand, cng directed a protein (Cng) of 10.1 kDa in E. coli under the control of T7 promoter. Gel mobility-shift assays demonstrated that Cng binds specifically to a DNA region containing the GATAC-boxes. In addition, primer extension analyses demonstrated that the two sequences pR and pL act as a promoter in L. plantarum as well as in E. coli. These results suggested that the potential promoters pR and pL probably function for the lytic and lysogenic pathways, respectively, and Cng may act as a repressor presumably through the GATAC-boxes as operators.othe
