Epidemiological Characteristics

Objective.To determine whether the molecular epidemiological characteristics of methicillin-resistantStaphylococcus aureus(MRSA) had changed in a level III neonatal intensive care unit (NICU).Design.Retrospective review of medical records.Setting.Level III NICU of a university-affiliated children's hospital in New York, New York.Patients.Case patients were neonates hospitalized in the NICU who were colonized or infected with MRSA.Methods.Rates of colonization and infection with MRSA during the period from 2000 through 2008 were assessed. Staphylococcal chromosomal cassette (SCC)mecAanalysis and genotyping forS. aureusencoding protein A (spa) were performed on representative MRSA isolates from each clonal pulsed-field gel electrophoresis pattern.Results.Endemic MRSA infection and colonization occurred throughout the study period, which was punctuated by 4 epidemiologic investigations during outbreak periods. During the study period, 93 neonates were infected and 167 were colonized with MRSA. Surveillance cultures were performed for 1,336 neonates during outbreak investigations, and 115 (8.6%) neonates had MRSA-positive culture results. During 2001-2004, healthcare-associated MRSA clones, carrying SCCmectype II, predominated. From 2005 on, most MRSA clones were community-associated MRSA with SCCmectype IV, and in 2007, USA300 emerged as the principal clone.Conclusions.Molecular analysis demonstrated a shift from healthcare-associated MRSA (2001-2004) to community-associated MRSA (2005-2008).

The frequency and clinical significance of Staphylococcus epidermidis isolates from blood cultures of neonates collected during a 17-month period in The New York Hospital neonatal intensive care unit (NICU) were reviewed. Twenty-three episodes of clinically significant S epidermidis bacteremia were detected using the criteria of isolation from 3/3 blood culture bottles from a single culture, or isolation from two or more blood cultures taken at different times, or simultaneous isolation from blood and fluid, pus or vascular catheter. Of these 23 episodes of S epidermidis bacteremia, ten were associated with colonized vascular catheters, and four episodes occurred in infants with necrotizing enterocolitis. Focal S epidermidis infection occurred in ten episodes, and persistent bacteremia occurred frequently in this setting. S epidermidis was the most frequent cause of bacteremia in the Neonatal Intensive Care Unit during the period reviewed. Of the isolates determined to be clinically significant, 74% were resistant to methicillin and cephalothin and 91% were resistant to gentamicin. All isolates were sensitive to vancomycin. In addition to removing vascular catheters suspected of being colonized and searching for potential sites of focal infection, an antibiotic regimen that includes vancomycin should be initiated once significant S epidermidis bacteremia has been recognized in the neonate.

We performed a molecular and epidemiologic study of a healthcare-associated rhinovirus outbreak to better understand transmission in neonatal intensive care settings. Sequencing of the 7 outbreak strains revealed 4 distinct clades, indicating multiple sources. A single clade infected 3 patients in adjacent rooms, suggesting horizontal transmission. We observed 1 rhinovirus-associated death.

Descriptive retrospective Research with quantitative approach. Aims: Meet the epidemiological characteristics of hospitalization in Neonatal intensive care unit, relating them to the possible maternal factors, in a public maternity in southern Brazil. Performed with newborns that they put in the NICU, forwarded with the clinical summary to the Municipal program precious baby. The data were collected, with the following variables: maternal age, type of birth, number of pre-natal consultations, complications in pregnancy, and number of days of hospitalization in neonatal intensive care unit, in the period from January to December 2013. Were analyzed medical records 72, prematurity was the most prevalent with 61% of the babies, and their consequences such as the use of mechanical ventilation and apneas 55.5% were repeated and 52.7% respectively. Among the most frequent maternal complications was observed the Preterm Labor (31.3%) and premature rupture of membranes (23.8%). Thus the identification of the factors that lead to preterm labor and premature rupture of membranes, could meet the maternal background and consequently reduce the prematurity and low birth weight.

Introduction: Personal digital assistants (PDAs) used in electronic laboratory-based surveillance are a promising alternative to conventional surveillance to detect healthcare-associated infections (HAIs). The aim of the study was to monitor, detect, and analyze HAIs using PDAs in a neonatal intensive care unit (NICU). Methodology: In this descriptive study, 1,053 neonates admitted to the NICU in the obstetrics and gynecology ward at the Cairo University hospital were included and evaluated for HAIs by collecting data using PDAs programmed by Naval Medical Research Unit 3, Cairo, with the definitions for HAIs provided by the National Healthcare Safety Network of the Centers for Disease Control and Prevention. Case records were reviewed three times a week over 19 months, from March 2012 to September 2013. Results: Of 124 suspected episodes of infection recorded in PDAs, 89 confirmed episodes of infection were identified. HAI and NICU infection rates were 7.4 and 2.72/1,000 patient-days, respectively. Primary bloodstream infection was detected in 81 episodes and pneumonia in 8 episodes. The majority of infections (62%) were acquired in the ward before NICU admission. Klebsiella spp. was isolated most frequently (42%), followed by coagulase-negative Staphylococci (31%). Conclusions: This study is the first to report the use of PDAs in surveillance to detect HAIs in the NICU in our hospital. The majority of infections were acquired at the obstetric care department, indicating the importance of implementing rigorous prevention and control programs and a more detailed surveillance to identify other risk factors for infections.
