Abstract
OBJECTIVES Neonatal sepsis is one of the leading causes of neonatal deaths in neonatal intensive care units. Hence, it is essential to review the evidence from systematic reviews on interventions for reducing late-onset sepsis (LOS) in neonates. METHODS PubMed and the Cochrane Central were searched from inception through August 2020 without any language restriction. Cochrane reviews of randomized clinical trials (RCTs) assessing any intervention in the neonatal period and including one or more RCTs reporting LOS. Two authors independently performed screening, data extraction, assessed the quality of evidence using Cochrane Grading of Recommendations Assessment, Development and Evaluation, and assessed the quality of reviews using a measurement tool to assess of multiple systematic reviews 2 tool. RESULTS A total of 101 high-quality Cochrane reviews involving 612 RCTs and 193,713 neonates, evaluating 141 interventions were included. High-quality evidence showed a reduction in any or culture-proven LOS using antibiotic lock therapy for neonates with central venous catheters (CVC). Moderate-quality evidence showed a decrease in any LOS with antibiotic prophylaxis or vancomycin prophylaxis for neonates with CVC, chlorhexidine for skin or cord care, and kangaroo care for low birth weight babies. Similarly, moderate-quality evidence showed reduced culture-proven LOS with intravenous immunoglobulin prophylaxis for preterm infants and probiotic supplementation for very low birth weight (VLBW) infants. Lastly, moderate-quality evidence showed a reduction in fungal LOS with the use of systemic antifungal prophylaxis in VLBW infants. CONCLUSIONS The overview summarizes the evidence from the Cochrane reviews assessing interventions for reducing LOS in neonates, and can be utilized by clinicians, researchers, policymakers, and consumers for decision-making and translating evidence into clinical practice.

Abstract
OBJECTIVE With no consensus, the practice of using prophylactic antibiotics prior to central venous catheter (CVC) removal in NICU patients remains controversial. The objective of this study was to compare the incidence of sepsis post-CVC removal in those who received a dose of vancomycin prophylactically with those who did not. METHODS This single-center, retrospective chart review included NICU patients who had CVCs removed. Patients were excluded if they had a confirmed or suspected infection at the time of CVC removal or if the indwelling CVC was removed prior to 30 days from insertion. Primary outcome was the occurrence of a sepsis evaluation within 72 hours from CVC removal. Secondary outcomes included the development of acute kidney injury, source and identification of positive cultures, time to onset of suspected or confirmed sepsis, and the appropriate administration of intravenous vancomycin. RESULTS Eighty-two CVC removals received prophylactic vancomycin (P-VAN), and 22 CVCs did not receive prophylactic vancomycin (NP-VAN) prior to CVC removal. There were no significant differences in patient demographics between groups and median duration of indwelling CVC. Two clinical sepsis evaluations occurred in the P-VAN group compared with none in the NP-VAN group. Of all the P-VAN CVC removals, 45 (55%) received vancomycin appropriately. There were no statistical differences in all evaluated secondary outcomes. CONCLUSIONS Vancomycin administered prophylactically prior to CVC removal did not reduce the number of subsequent clinical sepsis evaluations or infections in NICU patients.

Abstract
BACKGROUND Neonatal sepsis is a major cause of morbidity and mortality. It is the third leading cause of neonatal mortality globally constituting 13% of overall neonatal mortality. Despite the high burden of neonatal sepsis, high-quality evidence in diagnosis and treatment is scarce. Due to the diagnostic challenges of sepsis and the relative immunosuppression of the newborn, many neonates receive antibiotics for suspected sepsis. Antibiotics have become the most used therapeutics in neonatal intensive care units, and observational studies in high-income countries suggest that 83% to 94% of newborns treated with antibiotics for suspected sepsis have negative blood cultures. The last Cochrane Review was updated in 2005. There is a need for an updated systematic review assessing the effects of different antibiotic regimens for late-onset neonatal sepsis. OBJECTIVES To assess the beneficial and harmful effects of different antibiotic regimens for late-onset neonatal sepsis. SEARCH METHODS We searched the following electronic databases: CENTRAL (2021, Issue 3); Ovid MEDLINE; Embase Ovid; CINAHL; LILACS; Science Citation Index EXPANDED and Conference Proceedings Citation Index - Science on 12 March 2021. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA We included RCTs comparing different antibiotic regimens for late-onset neonatal sepsis. We included participants older than 72 hours of life at randomisation, suspected or diagnosed with neonatal sepsis, meningitis, osteomyelitis, endocarditis, or necrotising enterocolitis. We excluded trials that assessed treatment of fungal infections. DATA COLLECTION AND ANALYSIS Three review authors independently assessed studies for inclusion, extracted data, and assessed risk of bias. We used the GRADE approach to assess the certainty of evidence. Our primary outcome was all-cause mortality, and our secondary outcomes were: serious adverse events, respiratory support, circulatory support, nephrotoxicity, neurological developmental impairment, necrotising enterocolitis, and ototoxicity. Our primary time point of interest was at maximum follow-up. MAIN RESULTS We included five RCTs (580 participants). All trials were at high risk of bias, and had very low-certainty evidence. The five included trials assessed five different comparisons of antibiotics. We did not conduct a meta-analysis due to lack of relevant data. Of the five included trials one trial compared cefazolin plus amikacin with vancomycin plus amikacin; one trial compared ticarcillin plus clavulanic acid with flucloxacillin plus gentamicin; one trial compared cloxacillin plus amikacin with cefotaxime plus gentamicin; one trial compared meropenem with standard care (ampicillin plus gentamicin or cefotaxime plus gentamicin); and one trial compared vancomycin plus gentamicin with vancomycin plus aztreonam. None of the five comparisons found any evidence of a difference when assessing all-cause mortality, serious adverse events, circulatory support, nephrotoxicity, neurological developmental impairment, or necrotising enterocolitis; however, none of the trials were near an information size that could contribute significantly to the evidence of the comparative benefits and risks of any particular antibiotic regimen. None of the trials assessed respiratory support or ototoxicity. The benefits and harms of different antibiotic regimens remain unclear due to the lack of well-powered trials and the high risk of systematic errors. AUTHORS' CONCLUSIONS Current evidence is insufficient to support any antibiotic regimen being superior to another. RCTs assessing different antibiotic regimens in late-onset neonatal sepsis with low risks of bias are warranted.

Abstract
Suspected or proven late onset sepsis, necrotizing enterocolitis, urinary tract infections, and ventilator associated pneumonia occurring after the first postnatal days contribute significantly to the total antibiotic exposures in neonatal intensive care units. The variability in definitions and diagnostic criteria in these conditions lead to unnecessary antibiotic use. The length of treatment and choice of antimicrobial agents for presumed and proven episodes also vary among centers due to a lack of supportive evidence and guidelines. Implementation of robust antibiotic stewardship programs can encourage compliance with appropriate dosages and narrow-spectrum regimens.

Abstract
Necrotising enterocolitis (NEC) and sepsis are serious diseases of preterm infants that can result in feeding intolerance, the need for bowel resection, impaired physiological and neurological development, and high mortality rates. Neonatal healthcare improvements have allowed greater survival rates in preterm infants leading to increased numbers at risk of developing NEC and sepsis. Gut bacteria play a role in protection from or propensity to these conditions and have therefore, been studied extensively using targeted 16S rRNA gene sequencing methods. However, exact epidemiology of these conditions remain unknown and the role of the gut microbiota in NEC remains enigmatic. Many studies have confounding variables such as differing clinical intervention strategies or major methodological issues such as the inability of 16S rRNA gene sequencing methods to determine viable from non-viable taxa. Identification of viable community members is important to identify links between the microbiota and disease in the highly unstable preterm infant gut. This is especially important as remnant DNA is robust and persists in the sampling environment following cell death. Chelation of such DNA prevents downstream amplification and inclusion in microbiota characterisation. This study validates use of propidium monoazide (PMA), a DNA chelating agent that is excluded by an undamaged bacterial membrane, to reduce bias associated with 16S rRNA gene analysis of clinical stool samples. We aim to improve identification of the viable microbiota in order to increase the accuracy of clinical inferences made regarding the impact of the preterm gut microbiota on health and disease. Gut microbiota analysis was completed on stools from matched twins (n = 16) that received probiotics. Samples were treated with PMA, prior to bacterial DNA extraction. Meta-analysis highlighted a significant reduction in bacterial diversity in 68.8% of PMA treated samples as well as significantly reduced overall rare taxa abundance. Importantly, overall abundances of genera associated with protection from and propensity to NEC and sepsis such as: Bifidobacterium; Clostridium, and Staphylococcus sp. were significantly different following PMA-treatment. These results suggest non-viable cell exclusion by PMA-treatment reduces bias in gut microbiota analysis from which clinical inferences regarding patient susceptibility to NEC and sepsis are made.

Abstract
OBJECTIVES Evaluate the incidence of postcatheter removal clinical sepsis when antibiotics were infused prior to the removal of percutaneously inserted central venous catheters (PICCs). METHODS A retrospective chart review of premature neonates (n = 196) weighing ≤1250 g at birth with 218 PICC line removals in the presence or absence of antibiotics at a tertiary level neonatal intensive care unit (NICU) between January 1, 2010, and May 31, 2012. Charts were reviewed looking for the presence of clinical sepsis defined as a sepsis workup including white blood cell count, differential, C-reactive protein, blood and/or cerebral spinal fluid (CSF), and urine cultures along with at least 48 hours of antibiotic therapy given within 72 hours after removal of a PICC line. Antibiotics were considered present at line removal if given within 12 hours before catheter removal either electively or at completion of a planned course. RESULTS When antibiotics were given within 12 hours before PICC line removal, only 2% of the line removal episodes (1/48) resulted in a neonate developing clinical sepsis versus 13% (21/165) when no antibiotics were given prior to removal (p = 0.03, Fisher's exact test). Despite the increased use of elective antibiotics with line removal, there was no increase in total antibiotic usage due to the overall decrease in episodes of clinical sepsis or changes in antibiogram susceptibility patterns. CONCLUSIONS There was an 11% absolute decrease and a 6-fold relative decrease in postcatheter removal clinical sepsis events in premature neonates who received antibiotics prior to PICC line removal.

Abstract
The objective of this study was to assess the frequency of blood culture (BC) collection among neonates who received vancomycin. Demographic, clinical, microbiologic, and pharmacy data were collected for 1275 neonates (postnatal age 0-27 days) who received vancomycin at an Intermountain Healthcare facility between 1/2006 and 9/2011. Neonates treated with vancomycin had a BC collected 94 % (n = 1198) of the time, of which 37 % (n = 448) grew one or more bacterial organisms (BC positive). Of these, 1 % (n = 5) grew methicillin-resistant Staphylococcus aureus (MRSA), 71 % (n = 320) grew coagulase-negative Staphylococci (CoNS), 9 % (n = 40) grew methicillin-sensitive Staphylococcus aureus (MSSA), and 22 % (n = 97) grew other bacterial species (total exceeds 100 % due to co-detection). In patients with negative BC or no BC, vancomycin therapy was extended beyond 72 h 52 % of the time. The median duration of vancomycin therapy for patients with a negative BC was 4 (IQR: 2-10) days. BCs were frequently obtained among neonates who received vancomycin. Vancomycin therapy beyond the conventional 'empiric' treatment window of 48-72 h was common without isolation of resistant gram-positive bacteria.

Abstract
Neonates, especially those born prematurely, are at high risk of morbidity and mortality from sepsis. Multiple factors, including prematurity, invasive life-saving medical interventions, and immaturity of the innate immune system, put these infants at greater risk of developing infection. Although advanced neonatal care enables us to save even the most preterm neonates, the very interventions sustaining those who are hospitalized concurrently expose them to serious infections due to common nosocomial pathogens, particularly coagulase-negative staphylococci bacteria (CoNS). Moreover, the health burden from infection in these infants remains unacceptably high despite continuing efforts. In this paper, we review the epidemiology, immunological risk factors, diagnosis, prevention, treatment, and outcomes of neonatal infection due to the predominant neonatal pathogen CoNS.

Abstract
Antimicrobial treatment is a mainstay therapy in the neo-natal intensive care unit (NICU). Given the lack of specificity for clinical symptoms of infection in the newborn and the overwhelming impact of infection with rapid multisystem dissemination, NICU providers tend to treat early while awaiting laboratory results. With the high vulnerability of our special population to a variety of potential infecting microbes, a combination of antibiotics is preferred for initial treatment. The selection of these antibiotics is based on the known or presumed environment of exposure. If the newborn is within a week of birth, we can reasonably expect the likely environment of exposure is the community or the mother. If the newborn is older or has undergone numerous procedures, we can presume the exposure is more likely to be hospital-based.

Abstract
Antimicrobial-resistant pathogens are of increasing concern in the neonatal intensive care unit population. A myriad of resistance mechanisms exist in microorganisms, and management can be complex because broad-spectrum antibiotics are increasingly needed. Control and prevention of antibiotic-resistant organisms (AROs) require an interdisciplinary team with continual surveillance. Judicious use of antibiotics; minimizing exposure to risk factors, when feasible; and effective hand hygiene are crucial interventions to reduce infection and transmission of AROs.

Abstract
BACKGROUND Evidence is contradictory whether very low-birth-weight (VLBW, birth weight <1500 g) infants with early neutropenia (NP), especially those born to mothers with preeclampsia experience a greater incidence of nosocomial infection (NI). OBJECTIVE To investigate whether NP within the first 7 days of life is a risk factor for NI in VLBW infants. METHODS Over a 42-month period, we identified all VLBW infants born at <or=34 weeks gestation who survived for more than 72 h. Infants who had no evidence of early infection, who had at least one complete blood count performed in the first week of life, and who were not given prophylactic recombinant human granulocyte colony-stimulating factor (rhG-CSF) were included in this retrospective study. Early NP was defined as an absolute neutrophil count less than 1500 per microl at any time during the first week of life. NI was defined as the culture of a bacterial or fungal pathogen from a sterile body fluid that was obtained after 72 h of life in an infant with one or more clinical signs of infection. RESULTS A total of 338 VLBW infants were reviewed. Of those, 51 infants were excluded because of death or onset of an infection before 72 h of age, lack of a complete blood count in the first week of life or treatment with rhG-CSF. Of the remaining 287 infants, NI occurred in 11 of 77 (14.3%) infants with early NP compared to 42 of 210 (20.0%) infants without early NP (P=0.31). Infants who developed NI were smaller and less mature, had lower Apgar scores, were more frequently instrumented with central lines and required a longer duration of parenteral nutrition compared to infants without NI. Infants with NI also had a higher mortality and a greater incidence of necrotizing enterocolitis, severe intraventricular hemorrhage and threshold retinopathy of prematurity. However, using stepwise multivariate logistic regression analysis, only the duration of parenteral nutrition and gestational age were significant risk factors for NI. CONCLUSION Our data do not support the hypothesis that early NP increases the risk for NI in VLBW infants.

Abstract
LATE-ONSET SEPSIS AMONG very low birth weight (VLBW) and extremely low birth weight (ELBW) neonates is a troubling occurrence. The most recently published data from the National Nosocomial Infection Surveillance system documents 5.4 umbilical- and central line–related bloodstream infections (BSIs) per 1,000 catheter days in infants weighing between 1,001 and 1,500 g.1 For infants weighing 1,000 g or less, the rate is 9.1 infections per 1,000 catheter days. A variety of factors, including prematurity and related relative immunocompromise, altered skin integrity, and multiple invasive procedures, places VLBW and ELBW neonates at risk for infection. Tunneled central catheters or peripherally inserted central catheters (PICCs) clearly add to the risk of infection in these vulnerable patients. In a point prevalence survey of a network of 29 NICUs, researchers found that coagulase-negative Staphylococcus (CoNS) was the causative organism in nearly half (48.3 percent) of the documented bloodstream infections.2 Vancomycin prophylaxis is a potential strategy for the prevention of late-onset sepsis associated with CoNS. This column explores the efficacy and safety of this strategy.

Abstract
BACKGROUND Parenteral nutrition for neonates may be delivered via a short peripheral cannula or a central venous catheter. The latter may either be inserted via the umbilicus or percutaneously. Because of the complications associated with umbilical venous catheter use, many neonatal units prefer to use percutaneously inserted catheters following the initial stabilisation period. The method of parenteral nutrition delivery may affect nutrient input and consequently growth and development. Although potentially more difficult to place, percutaneous central venous catheters may be more stable than peripheral cannulae, and need less frequent replacement. These delivery methods may also be associated with different risks of adverse events, including acquired systemic infection and extravasation injury. OBJECTIVES To determine the effect of infusion via a percutaneous central venous catheter versus a peripheral cannula on nutrient input, growth and development, and complications including systemic infection, or extravasation injuries in newborn infants who require parenteral nutrition. SEARCH STRATEGY The standard search strategy of the Cochrane Neonatal Review Group was used. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2007), MEDLINE (1966 - February 2007), EMBASE (1980 - February 2007), conference proceedings, and previous reviews. SELECTION CRITERIA Randomised controlled trials that compared the effect of delivering parenteral nutrition via a percutaneous central venous catheter versus a peripheral cannulae in neonates. DATA COLLECTION AND ANALYSIS Data were extracted the data using the standard methods of the Cochrane Neonatal Review Group, with separate evaluation of trial quality and data extraction by each author, and synthesis of data using relative risk, risk difference and mean difference. MAIN RESULTS Four trials eligible for inclusion were found. These trials recruited a total of 368 infants and reported a number of different outcomes. One study showed that the use of a percutaneous central venous catheter was associated with a decreased risk of cumulative nutritional deficit during the trial period: Mean difference in the percentage of the prescribed nutritional intake actually received: -7.1% (95% confidence interval -11.02, -3.2). In another trial, infants in the percutaneous central venous catheter group needed significantly fewer catheters/cannulae per infant during the trial period: Mean difference in the number of catheters/cannulae per infant: -3.2 (95% confidence interval -5.13, -1.27). Meta-analysis of data from all four trials did not find any evidence of an effect on the incidence of systemic infection: Typical relative risk: 0.94 (95% confidence interval 0.70, 1.25); typical risk difference: -0.02 (95% confidence interval -0.12, 0.08). AUTHORS' CONCLUSIONS Data from one small study suggest that the use of a percutaneous central venous catheter to deliver parenteral nutrition in newborn infants improves nutrient input. The significance of this in relation to long-term growth and developmental outcomes is unclear. Another study suggested that the use of a percutaneous central venous catheter rather than a peripheral cannula decreases the number of catheters/cannulae needed to deliver the nutrition. No evidence was found to suggest that percutaneous central venous catheter use increased the risk of adverse events, particularly systemic infection.

Abstract
BACKGROUND Controversy surrounds the source (skin vs mucosa) of coagulase-negative staphylococci (CoNS) bacteremia in cancer patients. Determining the source of this infection has clinical and epidemiologic implications. OBJECTIVE To determine the source(s) of CoNS bacteremia in cancer patients. METHODS Between November 1998 and October 2000, cultures of nasal and rectal mucosa and skin at central venous catheter (CVC) sites were obtained in 62 patients (66 episodes) with CoNS-positive blood culture(s). Bacteremia was classified as true, indeterminate, or unlikely on the basis of clinical and microbiologic findings. Molecular relatedness of strains isolated from the blood and from colonized sites of patients with true and those with unlikely bacteremia was examined using pulsed-field gel electrophoresis (PFGE). RESULTS CoNS colonization was present in 55 episodes (83%). The nasal mucosa was the most frequently colonized site (86%), followed by rectal mucosa (40%) and skin at site of CVC insertion (38%) (P < .001). Colonization at > or =1 site was common. True and unlikely bacteremia accounted for 11 and 10 episodes, respectively, with the remaining 45 episodes considered undetermined or had negative surveillance cultures. Among patients with true bacteremia, 6 mucosal isolates and only 1 skin isolate were related by PFGE to the blood isolate recovered from the same patient. CONCLUSION Mucosa is the most common site of CoNS colonization and is the likely source of CoNS bacteremia in cancer patients.

Abstract
Twenty percent of very-low-birth-weight (<1500 g) preterm infants experience a serious systemic infection, and despite advances in neonatal intensive care and antimicrobials, mortality is as much as threefold higher for these infants who develop sepsis than their counterparts without sepsis during their hospitalization. Outcomes may be improved by preventative strategies, earlier and accurate diagnosis, and adjunct therapies to combat infection and protect the vulnerable preterm infant during an infection. Earlier diagnosis on the basis of factors such as abnormal heart rate characteristics may offer the ability to initiate treatment prior to the onset of clinical symptoms. Molecular and adjunctive diagnostics may also aid in diagnosing invasive infection when clinical symptoms indicate infection but no organisms are isolated in culture. Due to the high morbidity and mortality, preventative and adjunctive therapies are needed. Prophylaxis has been effective in preventing early-onset group B streptococcal sepsis and late-onset Candida sepsis. Future research in prophylaxis using active and passive immunization strategies offers prevention without the risk of resistance to antimicrobials. Identification of the differences in neonatal intensive care units with low and high infection rates and implementation of infection control measures remain paramount in each neonatal intensive care unit caring for preterm infants.

Abstract
Nosocomial infections with coagulase negative staphylococcus (CoNS) are a frequent and significant cause of morbidity in the preterm infant. Infections diagnosed after the first 72 hours of life are arbitrarily deemed to be "nosocomial." There are many difficulties encountered in efforts to evaluate and compare nosocomial sepsis in the NICU. An issue of primary concern is the lack of uniformity in the definition of sepsis in the NICU. Based on the frequency of positive blood cultures in infants less than 1000 g, it appears reasonable to evaluate methods for the prevention of nosocomial sepsis. These include prophylactic antibiotic administration, antiseptic impregnated catheters, and the use of an antibiotic lock technique.

Abstract
BACKGROUND Nosocomial, late onset sepsis occurs in up to 50% of infants of less than 1000gm at birth. The commonest organism isolated is coagulase negative staphylococcus (CoNS). A number of studies have evaluated the efficacy or prophylactic low dose vancomycin given either as a continuous infusion added to the infant's hyperalimentation fluid or by intermittent intravenous administration and these studies in very low birth weight infants are the subject of this review. OBJECTIVES To evaluate the safety and efficacy of vancomycin prophylaxis for the prevention of late-onset sepsis, coagulase negative staphylococcal sepsis, mortality, and effects on length of stay, total vancomycin exposure, evidence of vancomycin toxicity, and the development of vancomycin resistant organisms in the preterm neonate. SEARCH STRATEGY Searches were made of Medline, (MeSH terms: Vancomycin and Sepsis; limits: age groups, newborn infants), HealthStar and EMBase, electronic abstracts, personal files and conference proceedings. SELECTION CRITERIA Randomized controlled trials which compared the incidence of sepsis and mortality in preterm neonates receiving vancomycin prophylaxis versus a control group receiving no prophylaxis. DATA COLLECTION AND ANALYSIS Data regarding clinical outcomes including the overall incidence of sepsis, the incidence of coagulase negative staphylococcal sepsis, mortality, length of stay, total vancomycin exposure, evidence of vancomycin toxicity, and the development of vancomycin resistant organisms were excerpted from previous clinical trials. Data analysis was done in accordance with the standards of the Cochrane Neonatal Review Group. MAIN RESULTS The administration of prophylactic vancomycin reduced the incidence of both total neonatal nosocomial sepsis and coagulase negative staphylococcal sepsis in eligible preterm infants. Mortality, length of stay, and evidence of vancomycin toxicity were not significantly different between the two groups. There was insufficient evidence to ascertain the risks of development of vancomycin resistant organisms in the nurseries involved in these trials. REVIEWER'S CONCLUSIONS The use of prophylactic vancomycin in low doses reduces the incidence of nosocomial sepsis in the neonate. The methodologies of these studies may have contributed to the low rate of sepsis in the treated groups, as the blood cultures drawn from central lines may have failed to grow due to the low levels of vancomycin in the infusate. Although there is a theoretical concern regarding the development of resistant organisms with the administration of prophylactic antibiotic, there is insufficient evidence to ascertain the risks of development of vancomycin resistant organisms. Few clinically important benefits have been demonstrated for very low birth weight infants treated with prophylactic vancomycin. It therefore appears that routine prophylaxis with vancomycin should not be undertaken at present.
