Neonatal sepsis is a major cause of morbidity and mortality. Late-onset sepsis affects a significant percentage of infants admitted to the neonatal intensive care unit (NICU). Most affected newborns are preterm or low birth weight, but late-onset sepsis also affects late preterm and term infants. Understanding how gestational age affects the epidemiology of late-onset sepsis can be of use when defining strategies for its prevention and clinical management in NICU. Areas covered: Available evidence suggests the incidence and mortality of late-onset sepsis is higher in preterm and VLBW infants, but pathogen distribution and risk exposure is similar across all infants admitted to NICU...

BACKGROUND: Sepsis is a commonly encountered and potentially life-threatening problem in neonatal intensive care units, blood culture of neonatal sepsis helps in either optimizing treatment or terminating antibiotics. MATERIALS AND METHODS: We determined the causative agent, time to positivity (TTP), and antibiogram of neonatal blood cultures collected in a tertiary care center, to investigate difference between early- and late-onset neonatal sepsis and to establish the time at which a blood culture could safely be considered negative, using the BacT/ALERT(®) 3D 60...

The risks and benefits of feeding preterm formula (PF) versus donor human milk (DHM) in preterm infants are uncertain, and studies evaluating the efficacy of DHM to the morbidities and growth of preterm infants in the neonatal intensive care unit are confused by the need for milk fortification. We aimed to determine and compare the outcome of short-term morbidities in neonatal intensive care unit and growth between premature infants fed exclusively DHM only until a volume of 130 mL/kg/d of enteral feeding was achieved and infants fed with a PF mix after birth...

BACKGROUND: Preterm infants remain at high risk of adverse outcomes following necrotizing enterocolitis (NEC) and late onset sepsis (LOS). Meta-analysis of randomized trials has indicated a reduction in severe NEC following use of probiotics and bovine lactoferrin (LF). Overall, however, uncertainty remains over which probiotic, or combination to use. The aim of this study was to compare the incidence of severe NEC and LOS before and after routine supplementation with Lactobacillus GG (LGG) and LF...

Growing evidence supports the role of probiotics in reducing the risk of necrotizing enterocolitis, time to achieve full enteral feeding, and late-onset sepsis (LOS) in preterm infants. As reported for several neonatal clinical outcomes, recent data have suggested that nutrition might affect probiotics' efficacy. Nevertheless, the currently available literature does not explore the relationship between LOS prevention and type of feeding in preterm infants receiving probiotics. Thus, the aim of this systematic review and meta-analysis was to evaluate the effect of probiotics for LOS prevention in preterm infants according to type of feeding (exclusive human milk (HM) vs...

BACKGROUND: Use, timing and doses of surfactant in preterm infants are variable in practice in modern NICUs. OBJECTIVE: To explore the association between use and timing of surfactant administration and common neonatal adverse outcomes in preterm infants with gestational age (GA) < 28 weeks. MATERIAL AND METHODS: Neonates admitted to a participating Canadian Neonatal Network NICU between 2013 and 2015 were studied. Infants were divided into three groups based on surfactant administration: None, early (within 30 minutes of life), and late surfactant (> 30 minutes)...

BACKGROUND: The prognosis for late-onset sepsis depends largely on a timely diagnosis. We assess central-peripheral temperature difference monitoring as a marker for late-onset neonatal sepsis diagnosis. METHODS: We performed a prospective, observational study focusing on a cohort of 129 very low birth weight infants. Thermal gradient alteration was defined as a difference of > 2°C maintained during 4 hours. We then determined its association with the late-onset sepsis variable through logistic regression...

Two main forms of osteopetrosis are recognized, a severe autosomal recessive form (MIM 259700) with an incidence of approximately 1 in 250,000 births and a mild autosomal dominant form (MIM166600) with an incidence of 1 in 20,000 births. Intrinsic disturbances of osteoclastic function due to mutations in genes encoding osteoclast-specific subunits of the vacuolar proton pump (TCIRG1, CLCN7) are found in most patients with recessive form. Mutations of CLCN7 are observed in dominant form of osteopetrosis .The recessive form of ostreopetrosis, i...

Preterm infants are highly susceptible to late-onset sepsis (LOS) and necrotizing enterocolitis (NEC), but disease pathogenesis and specific diagnostic markers are lacking. Circulating cell-free DNA (cfDNA) and immune cell-derived proteins are involved in multiple immune diseases in adults but have not been investigated in preterm neonates. We explored the relation of circulating neutrophil-associated proteins and cfDNA to LOS and/or NEC. Using a clinically relevant preterm pig model of spontaneous LOS and NEC development, we investigated neutrophil-associated proteins and cfDNA in plasma, together with cytokines in gut tissues...

BACKGROUND: Up to 7% of term and late-preterm neonates in high-income countries receive antibiotics during the first 3 days of life because of suspected early-onset sepsis. The prevalence of culture-proven early-onset sepsis is 0·1% or less in high-income countries, suggesting substantial overtreatment. We assess whether procalcitonin-guided decision making for suspected early-onset sepsis can safely reduce the duration of antibiotic treatment. METHODS: We did this randomised controlled intervention trial in Dutch (n=11), Swiss (n=4), Canadian (n=2), and Czech (n=1) hospitals...

BACKGROUND: Late-onset sepsis (LOS) is an important cause of death and neurodevelopmental impairment in premature infants. The purpose of this study was to assess overall incidence of LOS, distribution of LOS-causative organisms and center variation in incidence of LOS for extremely premature infants over time. METHODS: In a retrospective analysis of infants 401-1000 g birth weight and 22-28 6/7 weeks of gestational age born at 12 National Institute of Child Health and Human Development Neonatal Research Network centers in the years 2000-2005 (era 1) or 2006-2011 (era 2) who survived >72 hours, we compared the incidence of LOS and pathogen distribution in the 2 eras using the χ test...

BACKGROUND: Late onset sepsis (LOS) in preterm infants is associated with considerable morbidity and mortality. While studies have implicated gut bacteria in the aetiology of the disease, functional analysis and mechanistic insights are generally lacking. We performed temporal bacterial (n = 613) and metabolomic (n = 63) profiling on extensively sampled stool from 7 infants with LOS and 28 matched healthy (no LOS or NEC) controls. RESULTS: The bacteria isolated in diagnostic blood culture usually corresponded to the dominant bacterial genera in the gut microbiome...

BACKGROUND: Sepsis remains a major cause of morbidity and mortality among neonates. The risk factors and clinical outcomes of sepsis are poorly understood. Most cases of sepsis occurred mostly within the first week of newborns life related to perinatal risk factors. Late onset sepsis is related to hospital acquired infections which is seen after seven days of age. The purpose of this study was to assess clinical outcome and risk factors of neonatal sepsis in Felege Hiwot referral hospital Bahir Dar, North West Ethiopia...

Essentially, all neonates are exposed to infections, antibiotics, or vaccines early in their lives. This is especially true for those neonates born underweight or premature. In contrast to septic adults and children who are at an increased risk for subsequent infections, exposure to infection during the neonatal period is not associated with an increased risk of subsequent infection and may be paradoxically associated with reductions in late-onset sepsis (LOS) in the most premature infants. Perinatal inflammation is also associated with a decreased incidence of asthma and atopy later in life...

INTRODUCTION: There is a paucity of local data on neonatal outcomes of preterm/very-low-birth-weight infants in Hong Kong. This study aimed to evaluate the survival rate on discharge and morbidity of preterm/very-low-birth-weight infants (≤29+6 weeks and/or birth weight <1500 g) over a decade at Queen Mary Hospital in Hong Kong, so as to provide centre-specific data for prenatal counselling and to benchmark these results against the Vermont Oxford Network. METHODS: Standardised perinatal/neonatal data were collected for 449 infants with gestational age of 23+0 to 29+6 weeks and/or birth weight of <1500 g who were born at Queen Mary Hospital between 1 January 2005 and 31 December 2014...
