“…In relation to the frequency of isolation of coagulasenegative Staphylococcus, it was observed with less frequency than that seen by Moro et al (18). The presence of nonfermentative Gram-negative Pseudomonas aeruginosa and Acinetobacter baumanii were noted with more frequency, in agreement with the data reported by Morayta-Ramirez et al (17) and Karlowsky et al (10).…”

Central venous catheters from intensive care unit patients were subjected to microbiological methods (semiquantitative culture) and scanning electron microscopy in order to assess microbial attachment and correlate it with blood cultures. During the period of the survey, 59 patients with inserted central venous catheters were studied. The type of catheter used was nontunneled, noncuffed, single lumen, made of polyurethane. Blood samples for cultures were collected at the moment of catheter removal. Data on the patient's age, gender, catheter insertion site, and duration of catheterization were also obtained. From 63 catheters tips analysed, 30 (47.6%) showed microbial colonization. Infection proved to be more prevalent in 26 (41.3%) patients with catheters inserted via subclavia vein than in 2 (3.2%) inserted via the jugular vein. Infection was observed more frequently in catheters which were kept in place more than seven days. A. baumannii, Citrobacter freundii, E. aerogenes, P. aeruginosa and S. saprohyticus were isolated as causal agents of catheter-related bloodstream infections. The antimicrobial agent with greater in vitro activity against Gram-negative bacteria was imipenen and against Gram-positive were vancomycin, cefepime, penicillin, rifampin and tetracycline. The SEM analyses revealed biofilms on surfaces of all the catheters examined.

“…Several studies have found that bacterial colonization of the skin surrounding a central venous catheter at the insertion site is greater on men than on women, even when controlling for baseline colonization. [19][20][21][22] In addition, it has been suggested that hair growth and shaving interfere with wound dressing adherence, which could lead to a higher risk of infection among men who have thicker, coarser hair. 22 The fact that our study revealed no gender differences in infection rates among young children supports this theory, since gender differences in skin quality and hair growth are not pronounced in childhood.…”

BACKGROUND:Identifying patients most at risk for hospital-and community-associated infections is one essential strategy for preventing infections. OBJECTIVE: To investigate whether rates of community-and healthcare-associated bloodstream and surgical site infections varied by patient gender in a large cohort after controlling for a wide variety of possible confounders. DESIGN: Retrospective cohort study. PARTICIPANTS: All patients discharged from January 1, 2006 through December 31, 2008 (133,756 adult discharges and 66,592 pediatric discharges) from a 650-bed tertiary care hospital, a 220-bed community hospital, and a 280-bed pediatric acute care hospital within a large, academic medical center in New York, NY. MAIN MEASURES: Data were collected retrospectively from various electronic sources shared by the hospitals and linked using patients' unique medical record numbers. Infections were identified using previously validated computerized algorithms. KEY RESULTS: Odds of community-associated bloodstream infections, healthcare-associated bloodstream infections, and surgical site infections were significantly lower for women than for men after controlling for present-on-admission patient characteristics and events during the hospital stay [odds ratios (95 % confidence intervals) were 0. 85 (0.77-0.93), 0.82 (0.74-0.91), and 0.78 (0.68-0.91), respectively]. Gender differences were greatest for older adolescents (12-17 years) and adults 18-49 years and least for young children (<12 years) and older adults (≥70 years). CONCLUSIONS: In this cohort, men were at higher risk for bloodstream and surgical site infections, possibly due to differences in propensity for skin colonization or other anatomical differences.

“…The reason given is the absence of clear-cut discrimination between infected and colonised patients. However, studies conducted either in ICUs [36,55] or clinical haematology wards [33,56] have firmly established colonisation as an independent risk factor for systemic candidosis. This makes sense in relation to the natural pathophysiology of systemic candidosis, which is a dynamic process.…”
