Background.: Outer membrane protein A (OmpA) is a porin involved in Acinetobacter baumannii pathogenesis. However, OmpA clinical implication in hospital-acquired infections remains unknown. We aimed to determine whether OmpA overproduction was a risk factor associated with pneumonia, bacteremia, and mortality. Methods.: We analyzed demographic, microbiological, and clinical data from 100 patients included in a unicenter cohort and 246 included in a unicenter cohort and a multicenter cohort...

Hand decontamination is known to significantly reduce the spread of hospital-acquired infections but, despite a wealth of guidelines and education campaigns, evidence suggests that many healthcare workers are non-compliant with hand decontamination. The behaviours that prevent hand decontamination are complex. Studies look at attitudes towards dirt, disgust, self-protective hand washing and familiarity with patients. Self-protection behaviours manifest themselves in washing hands more often after certain tasks...

BACKGROUND: Surgical site infections (SSIs) are one of the most common hospital-acquired infections. To reduce SSIs, prophylactic intra-operative wound irrigation (pIOWI) has been advocated, although the results to date are equivocal. To develop recommendations for the new World Health Organization (WHO) SSI prevention guidelines, a systematic literature review and a meta-analysis were conducted on the effectiveness of pIOWI using different agents as a means of reducing SSI. METHODS: The PUBMED, Embase, CENTRAL, CINAHL, and WHO databases were searched...

BACKGROUND: Group A rotaviruses (RVA) are the leading cause of acute gastroenteritis (AGE) in young (aged <5 years) children, causing ∼250,000 deaths worldwide, mostly in developing countries. Differences on nucleotide sequences of VP7 (G-type) and VP4 (P-type) genes are the basis for the binary RVA nomenclature. Although at least 32 G-types and 47 P-types of rotavirus are presently known, most RVA infections in humans worldwide are related to five major G/P combinations: G1P[8], G2P[4], G3P[8], G4P[8], and G9P[8]...

Coagulase negative staphylococci are normal inhabitant of the human skin flora that account for an increasing number of infections, particularly hospital-acquired infections. Staphylococcus lugdunensis has emerged as a most virulent species causing various infections with clinical characteristics close to what clinicians usually observe with Staphylococcus aureus and both bacteria share more than 70% of their genome. Virulence of S. aureus relies on a large repertoire of virulence factors, many of which are encoded on mobile genetic elements...

BACKGROUND: Extended spectrum beta lactamases (ESBL) are responsible for increased resistance to third generation cephalosporins. Proteus species is an important cause of both community acquired and nosocomial infections. The Proteus spp is usually susceptible to beta lactam drugs but there is progressive increase in beta lactam resistance and recently ESBLs are also fast spreading to this species. OBJECTIVE: This study was conducted to study ESBL production and occurrence of TEM, SHV and CTX M beta lactamases in clinical isolates of Proteus spp in a tertiary care centre...

BACKGROUND: Hospital admissions for respiratory syncytial virus infection result in large health expenditures for Inuit infants. Palivizumab has been shown to be highly effective in reducing such admissions in preterm Inuit infants. We performed a cost-effectiveness analysis estimating the incremental cost-effectiveness ratio (ICER) for palivizumab prophylaxis per admission related to respiratory syncytial virus avoided in healthy term infants across the Canadian Arctic. METHODS: We compared universal palivizumab prophylaxis in term infants less than 6 months of age to no prophylaxis in 8 Arctic regions: the Northwest Territories, Nunavut, Nunavut without Iqaluit, the 3 subregions of Nunavut (Kitikmeot, Kivalliq and Qikiqtaaluk), the Qikiqtaaluk Region without Iqaluit, and Nunavik (northern Quebec)...

Hospitalized patients are at increased risk for acquiring healthcare-associated infections (HAIs) and inadequate nutrition. The human intestinal microbiota plays vital functions in nutrient supply and protection from pathogens, yet characterization of the microbiota of hospitalized patients is lacking. We used 16S rRNA amplicon sequencing to characterize the global pattern of microbial composition of fecal samples from 196 hospitalized patients with suspected infectious diarrhea in comparison to healthy, non-hospitalized subjects (n = 881), and to traditional culture results...

Background: Staphylococcus aureus possessing either the smr or qacA/B genes are associated with decreased susceptibility to chlorhexidine gluconate (CHG) and other antiseptics. Previous studies of antiseptic tolerant staphylococci have largely focused on high-risk populations and the exact role of healthcare exposure on acquisition of these organisms is unclear. We sought to describe the risk factors and features of infection caused by antiseptic tolerant S. aureus in a general pediatric population.Methods: Isolates were selected from an ongoing S...

REVIEW
Andi L Shane, Pablo J Sánchez, Barbara J Stoll
Neonatal sepsis is the cause of substantial morbidity and mortality. Precise estimates of neonatal sepsis burden vary by setting. Differing estimates of disease burden have been reported from high-income countries compared with reports from low-income and middle-income countries. The clinical manifestations range from subclinical infection to severe manifestations of focal or systemic disease. The source of the pathogen might be attributed to an in-utero infection, acquisition from maternal flora, or postnatal acquisition from the hospital or community...

BACKGROUND: Nosocomial pneumonias are common in trauma patients and so interventions to prevent and treat nosocomial pneumonia may improve outcomes. Our prior work strongly suggests that tissue injury predisposes to infections like nosocomial pneumonia because mitochondrial debris originating from injured cells contains damage-associated molecular patterns that can reduce neutrophil (PMN) migration into the airway and diminish PMN function in response to bacterial inoculation of the airway...
