ABSTRACT
In Iran, nurses are responsible for administering parenteral nutrition (PN) to hospitalized patients in intensive care units (ICUs). However, little information is available among nurses in Iran regarding best practices in PN administration. This study evaluates the performance of critical care nurses in Iran in the administration of PN. The performance of 50 nurses in the administration of PN in the ICU was observed 3 times during a 5-month period for a total of 150 observations. A researcher-developed checklist, "Critical Care Nurses' Performance in Parenteral Nutrition Administration," was used for data collection. The total score in this checklist ranged from 0 to 52. Based on the procedural steps in the checklist and whether the steps were performed appropriately, nurses' performance was scored as poor, moderate, or good. The mean score of nurses' performances in PN administration skills was 24.6 ± 2.5. This study found that 46 nurses had moderate skill levels in PN administration, and 3 demonstrated poor skills. Overall, the results indicated that critical care nurses in Iran have poor to moderate PN administration skills.

The aim of the present study was to assess performance of waste stabilization ponds (WSPs) on the removal of Listeria spp. in Isfahan, Iran. A total of 104 samples were taken from eight sampling locations from influent and effluent of a wastewater treatment plant (WWTP). Sewage samples were analyzed for the presence of Listeria spp. using selective enrichment protocol. Listeria isolates were also identified by biochemical and polymerase chain reaction (PCR) amplification. Listeria spp. was enumerated by a three tube most probable number (MPN) for total coliform counts (TC), fecal coliform counts (FC), total suspended solids (TSS), and total dissolved solids (TDS). In total, 54/104 (51.92%), 49/104 (47.11%), 36/104 (34.61%), and 27/104 (25.95%) samples were positive for Listeria spp., L. monocytogenes, L. innocua, and L. seeligeri, respectively. The mean MPN/100 mL enumeration of L. monocytogenes for influent, anaerobic, facultative ponds 1, 2, 3, 4 and maturation ponds 1 and 2 were 21.54, 10.61, 8, 5.77, 4, 2.54, 1.38, and 0.46, respectively. The removal percentage of Listeria spp. in the anaerobic, facultative, and maturation ponds were 44.71, 76.5, and 81.4%, respectively. Results showed that the WSPs were able to decrease the Listeria spp. levels significantly, although unable to remove them completely.
