Serratia marcescens ( S. marcescens ) is an Enterobacteriaceae microorganism that is widespread in the environment, which may be the source of nosocomial infections, rare in the newborn but severe, and often in the form of outbreaks. The aim of our study is to report our experience, during an outbreak of S. marcescens , to show the severity of this germ, with review of the literature. Our study was retrospective, including 8 newborns with S. marcescens nosocomial infection, collected in the neonatal intensive care unit of Mohammed VI University Medical Hospital, during the epidemic period, over a period of 2 months (July and August 2016)...

The incidence and severity of Clostridium difficile infection (CDI) remain high across intensive care units in the United States despite national efforts to decrease this escalating health care burden. Most published literature and guidelines address treatment rather than prevention, yet this approach may be too downstream to limit morbidity and mortality from the disease and its complications. Mechanisms to successfully prevent CDI include reducing modifiable risk factors and minimizing horizontal transmission of C...

OBJECTIVES: Antibiotic administration within 1 hour of hypotension has been shown to reduce mortality. It is unknown whether antibiotics before hypotension in children who eventually meet criteria for septic shock improves outcomes. This study assesses whether antibiotic timing from the time of meeting criteria for sepsis in children with septic shock impacts morbidity and mortality. METHODS: This is a retrospective study of children 18 years or younger presenting to a tertiary free-standing children's hospital emergency department with sepsis that subsequently progressed to septic shock and were admitted to an intensive care unit from 2008 to 2012...

Background: Risk-based guidelines aid empiric antibiotic selection for critically ill adults with suspected infection with Gram-negative bacilli with high potential for antibiotic resistance (termed high-risk GNRs). Neither evidence-based guidelines for empiric antibiotic selection nor validated risk factors predicting high-risk GNR growth exist for critically ill children. We developed and validated a model for predicting high-risk GNR growth in critically ill children with suspected infection...

Bacteria are closely related with human health and diseases. For example, the emergence of drug-resistant bacteria is a serious problem in the world. Studying the human microbiome shows its important role for our health. But we have very limited tools to edit bacterial population. Antibiotics are generally broad-spectrum and unable to kill only bad bacteria. The natural enemies of bacteria, called bacteriophage (phage), have highly specific host range, and thus promising candidates for targeted bacterial population editing...

OBJECTIVES: Patients undergoing stem cell transplant (SCT) for the treatment of hematologic malignancy are at increased risk for central line-associated bloodstream infections (CLABSIs). The use of prophylactic antibiotics to prevent CLABSIs in the setting of autologous SCT is of unclear benefit. We aimed to evaluate the impact of levofloxacin prophylaxis on reducing CLABSIs in this high-risk population. METHODS: Patients undergoing autologous SCT at a tertiary-care hospital received levofloxacin prophylaxis from January 13, 2016 to January 12, 2017...

Pregnancy in women with end-stage renal disease is rare. Multiple pregnancies carry a high risk of complications even in healthy individuals. We report the case of a 36-year-old woman who had four pregnancies while she was on dialysis, including one twin pregnancy. The last pregnancy occurred while in the 14th year of hemodialysis. At 8 weeks of gestation (WG), ultrasonography diagnosed a dichorionic diamniotic twin pregnancy. The frequency of dialysis was increased from 3 to 6 times a week and each session lasted 4 h...

Background: Biomarkers can facilitate safe antibiotic discontinuation in critically ill patients without bacterial infection. Methods: We tested the ability of a biomarker-based algorithm to reduce excess antibiotic administration in patients with systemic inflammatory response syndrome (SIRS) without bacterial infections (uninfected) in our pediatric intensive care unit (PICU). The algorithm suggested that PICU clinicians stop antibiotics if (1) C-reactive protein <4 mg/dL and procalcitonin <1 ng/mL at SIRS onset and (2) no evidence of bacterial infection by exam/testing by 48 hours...
