[PMID: 38778246 PMCID: PMC11112941 DOI: 10.1186/s12884-024-06583-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Accepted: 05/14/2024] [Indexed: 05/25/2024] Open
Abstract
BACKGROUND Neonatal sepsis is one of the most common causes of disease and death among neonates globally. And it made a great contribution to neonatal admission to intensive care units. To mitigate the ongoing neonatal crisis and accomplish the goal of sustainable development through a decrease in neonatal mortality, information from various regions is needed. Despite the considerable burden of neonatal sepsis in our setting, no prior studies were conducted in the study area. So, this study aimed to assess the magnitude and associated factors of neonatal sepsis among neonates admitted to the neonatal intensive care unit at Hawassa University Comprehensive Specialized Hospital, Sidama Regional State, Ethiopia. METHODS A hospital-based cross-sectional study was carried out among 287 neonates from March 1, 2020, to April 25, 2020. An interviewer-administered structured questionnaire was used to collect the data. The data were cleaned, coded, and entered into Epi Data 3.1 software and exported to Statistical Package for Social Science (SPSS) software version 23.0 for analysis. Binary logistic regression analyses were performed to identify variables having a significant association with neonatal sepsis. A p-value of ≤ 0.05 was considered statistically significant during multivariable logistic regression. RESULTS The study found that the magnitude of neonatal sepsis was 56%. The mean age of neonates was 3.2(SD±2.2) days. Around two-fifths (39%) of neonates were in the gestational age of <37 completed weeks. A quarter of mothers(25.8%) were delivered through cesarean section. During labor, 251 (87.5%) mothers had ≤4 digital vaginal examinations. Moreover, the finding revealed that mothers who delivered by cesarean section [AOR = 2.13, 95% CI (1.090-4.163)]. neonates who had been resuscitated at birth [AOR = 4.5, 95% CI (2.083-9.707)], and neonates who had NG tube inserted [AOR = 4.29, 95% CI (2.302-8.004)] were found to be significantly associated with neonatal sepsis. CONCLUSIONS The current study shows that neonatal sepsis was prevalent among more than half of the neonates admitted to the NICU. Therefore, designing strategies to enhance the aseptic techniques of professionals in the provision of care and actively and collaboratively working with cluster health facilities is highly recommended.

Abstract
Neonatal sepsis, as a significant cause of various complications and adverse outcomes in neonates, remains a serious health burden both domestically and internationally. Strategies such as antibiotic prophylaxis during delivery, the utilization of early-onset sepsis risk calculators, and quality improvement initiatives in neonatal wards are beneficial in alleviating the disease burden of neonatal sepsis. This paper provides a review of the epidemiology, risk factors, and recent advances in clinical management of neonatal sepsis.

Abstract
OBJECTIVES This study aimed to assess the incidence of late-onset sepsis (LOS), associated risk factors, and short-term prognosis in very low birth weight (VLBW) infants in a 10-year period. STUDY DESIGN A cohort study was conducted with 752 VLBW preterm infants-23 to 33 gestational weeks and 400 to 1,500 g birth weight-admitted to a neonatal intensive care unit from 2008 to 2017 and who survived over 72 hours. LOS was defined as clinical and laboratory signs of infection, whether or not confirmed by blood culture. VLBW infants were divided into groups and compared: no LOS versus proven LOS versus clinical LOS. Study variables included maternal, birth, and neonatal data, morbidities, procedures, etiological agents, and outcome-death, bronchopulmonary dysplasia (BPD), severe intraventricular hemorrhage, and retinopathy of prematurity (ROP). Analysis of variance with multiple Tukey's or Wald's comparison with gamma distribution, and stepwise multiple logistic regression model, adjusted for year, and gestational age, were used for statistical analysis. RESULTS LOS incidence was 39% (proven LOS: 29%; clinical LOS: 10%). Septic VLBW infants showed higher mortality (proven LOS: 23.2%; clinical LOS: 41.9%) compared with no LOS (8.9%). Coagulase-negative staphylococci (56%), Gram-negative (26%), and fungi (8%) were the most frequent etiological agents. In comparing the groups, septic VLBW infants had lower gestational age and birth weight, presented more morbidities, and underwent more invasive procedures. The risk factors for proven and clinical LOS were days of mechanical ventilation and parenteral nutrition. LOS was associated with increased risk of death, BPD, and ROP. CONCLUSION LOS showed high incidence and mortality, often caused by Gram-positive bacteria. Care interventions were the main risk factors associated. LOS had a major negative impact on short-term prognosis in VLBW infants. LOS reduction strategies are necessary and urgent. KEY POINTS · LOS is associated with clinically significant neonatal morbidities and death in VLBW premature infants.. · There is association between LOS and duration of intensive care interventions.. · Quality improvement initiatives can be a pathway for LOS reduction..

Pediatr Res 2024; 95:120-128. [PMID: 37648745 PMCID: PMC10798898 DOI: 10.1038/s41390-023-02794-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Revised: 07/10/2023] [Accepted: 08/14/2023] [Indexed: 09/01/2023]
Abstract
BACKGROUND Preterm infants show low blood levels of insulin-like growth factor 1 (IGF-1), known to be negatively correlated with Interleukin-6 (IL-6). We hypothesized that circulating IGF-1 is associated with systemic immune-markers following preterm birth and that exogenous IGF-1 supplementation modulates immune development in preterm pigs, used as model for preterm infants. METHODS Plasma levels of IGF-1 and 29 inflammatory markers were measured in very preterm infants (n = 221). In preterm pigs, systemic immune development, assessed by in vitro challenge, was compared between IGF-1 treated (2.25 mg/kg/day) and control animals. RESULTS Preterm infants with lowest gestational age and birth weight showed the lowest IGF-1 levels, which were correlated not only with IL-6, but a range of immune-markers. IGF-1 supplementation to preterm pigs reduced plasma IL-10 and Interferon-γ (IFN-γ), IL-2 responses to challenge and reduced expression of genes related to Th1 polarization. In vitro addition of IGF-1 (100 ng/mL) further reduced the IL-2 and IFN-γ responses but increased IL-10 response. CONCLUSIONS In preterm infants, plasma IGF-1 correlated with several immune markers, while supplementing IGF-1 to preterm pigs tended to reduce Th1 immune responses. Future studies should document whether IGF-1 supplementation to preterm infants affects immune development and sensitivity to infection. IMPACT Supplementation of insulin-like growth factor 1 (IGF-1) to preterm infants has been proposed to promote postnatal growth, but its impact on the developing immune system is largely unknown. In a cohort of very preterm infants, low gestational age and birth weight were the primary predictors of low plasma levels of IGF-1, which in turn were associated with plasma immune markers. Meanwhile, in immature preterm pigs, experimental supplementation of IGF-1 reduced Th1-related immune responses in early life. Supplementation of IGF-1 to preterm infants may affect the developing immune system, which needs consideration when evaluating overall impact on neonatal health.

Abstract
Objective General hospitals admit lower gestational age neonates than maternal and child health care centers, therefore associated with a higher morbidity and mortality. This study aimed to assess the etiology and clinical characteristics of neonatal sepsis in different medical setting models. Methods Neonates admitted to 5 tertiary medical centers, including one national general hospital, two maternal and child health care hospitals and two regional general hospitals, in central-south China with culture-proven sepsis between January 2010 and December 2019 were included in the study. We compared maternal and neonatal characteristics, pathogen distribution, treatment and neonatal outcomes among 3 different medical setting models in this retrospective cohort. Results We identified 757 episodes of culture-proven sepsis in 757 neonates. The predominant pathogens were coagulase-negative staphylococci, Klebsiella pneumoniae, Escherichia coli and Group B streptococci. A total of 683 neonates with detailed information were involved in further comparison; 54.6% were from the national general hospital, 35.9% were from the maternal and child health care hospital, and 9.5% were from the regional general hospital. Neonates in national and regional general hospitals had significantly lower gestational age and birthweight (P < 0.001). Patterns of pathogen distribution were different among these medical setting models. Early-onset sepsis was more common in maternal and child health care hospitals (61.4% vs. 42.1% vs. 46.7%, P < 0.001), while hospital-acquired late-onset sepsis was more common in national and regional general hospitals (32.7% vs. 33.3% vs. 11.4%, P < 0.001). The proportion of complications or comorbidities of neonates in maternal and child health care hospitals were significantly lower than neonates in national and regional general hospitals (P < 0.001). The case fatality rate was significantly higher in regional general hospitals (10.8% vs. 3.2% vs. 0.8%, P = 0.001). Conclusion We report distinct patterns of clinical characteristics, pathogens and outcomes in patient subgroups with neonatal sepsis from national general hospital, maternal and child health care hospital and regional general hospital. It might have some implications for improvement of prevention, management and empirical antibiotic use in neonatal sepsis in different setting models, especially in resource-limited settings from middle and low-income countries.

Abstract
BACKGROUND Delayed onset of minimal enteral nutrition compromises the immune response of preterm infants, increasing the risk of colonization and clinical complications (e.g., late-onset sepsis). This study aimed to analyze associations between late-onset sepsis in very low birth weight infants (<1500 g) and days of parenteral nutrition, days to reach full enteral nutrition, and maternal and nutritional factors. METHODS A cross-sectional study was carried out with very low birth weight infants admitted to a neonatal intensive care unit (NICU) of a reference maternity hospital of high-risk deliveries. Data regarding days of parenteral nutrition, days to reach full enteral nutrition, fasting days, extrauterine growth restriction, and NICU length of stay were extracted from online medical records. Late-onset sepsis was diagnosed (clinical or laboratory) after 48 h of life. Chi-squared, Mann-Whitney tests, and binary logistic regression were applied. RESULTS A total of 97 preterm infants were included. Of those, 75 presented late-onset sepsis with clinical (n = 40) or laboratory (n = 35) diagnosis. Maternal urinary tract infection, prolonged parenteral nutrition (>14 days), and extrauterine growth restriction presented 4.24-fold, 4.86-fold, and 4.90-fold higher chance of late-onset sepsis, respectively. CONCLUSION Very low birth weight infants with late-onset sepsis had prolonged parenteral nutrition and took longer to reach full enteral nutrition. They also presented a higher prevalence of extrauterine growth restriction than infants without late-onset sepsis.

Abstract
OBJECTIVE To evaluate the regional etiology, antimicrobial resistance (AMR) pattern, and risk factors in neonates with sepsis in China. METHODS We performed a systematic review and meta-analysis by searching Medline, Embase, Scopus, and Web of Science in December 2020. Studies of neonatal sepsis from China published between 2011 and 2020 were included. We pooled the proportion of pathogens and calculated the odds ratios of risk factors with 95% CIs using a random-effects model. RESULTS We included 29 studies of 164,750 neonates with sepsis. The studies comprise data from 1990 to 2019. Coagulase-negative staphylococci (CoNS), Escherichia coli and Klebsiella spp accounted for 33% (95% CI 24-43), 17% (13-20), and 14% (11-17), respectively. Group B streptococcus (GBS) was the predominant isolate in early-onset sepsis (EOS) (21%, 95% CI 10-31), while the proportion of CoNS was the largest in late-onset sepsis (LOS) (32%, 95% CI 22-43). Resistance of CoNS to penicillin was found in 95% (95% CI 92-98) of 511 cases and Klebsiella spp to ampicillin in 95% (95% CI 90-99) of 364 cases. Maternal underlying diseases (2.61, 95% CI 1.48-4.61), mechanical ventilation (2.41, 1.37-4.23), central venous catheter placement (2.74, 1.77-4.26), peripherally inserted central catheter (PICC) placement (4.26, 2.80-6.49), multiple antibiotic uses (5.35, 1.85-15.43) and total parenteral nutrition (7.96, 2.04-31.02) were risk factors of neonatal sepsis. CONCLUSION CoNS, E. coli, and Klebsiella spp were the predominant pathogens in neonatal sepsis in China. AMR was still a significant issue in NICUs. Total parenteral nutrition, multiple antibiotic uses, and PICC placement were the most relevant risk factors.

Abstract
Infants born before 28 weeks are at risk of contracting healthcare-associated infections (HAIs), which could be caused by pathogens residing on contaminated hospital surfaces. In this longitudinal study, we characterized by NGS the bacterial composition of nasal swabs of preterm newborns, at the time of birth and after admission to the Neonatal Intensive Care Unit (NICU), comparing it with that of the environmental wards at the time of delivery and during the hospitalization. We characterized the resistome on the samples too. The results showed that environmental microorganisms responsible for HAIs, in particular Staphylococcus spp., Streptococcus spp., Escherichia-Shigella spp., and K. pneumoniae, were detected in higher percentages in the noses of the babies after 13 days of hospitalization, in terms of the number of colonized patients, microorganism amount, and relative abundance. The analysis of nasal bacteria resistome evidenced the absence of resistance genes at the time of birth, some of which appeared and increased after the admission in the NICU. These data suggest that hospital surface microbiota might be transported to respiratory mucosae or other profound tissues. Our study highlights the importance of a screening that allows characterizing the microbial profile of the environment to assess the risk of colonization of the newborn.

BACKGROUND Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in preterm infants. Survivors may suffer both short- and long-term morbidities. Current evidence suggests that the incidence of NEC can be reduced by standardizing the care delivery in addressing key risk factors including an altered gut microbiome, use of formula milk, hyperosmolar feeds, and unrestricted use of high-risk medications METHODS: Since 2014, the department has a workgroup who analyzed all cases of NEC within a month of diagnosis to identify preventable risk factors. Existing evidence-based quality improvement strategies were revised and new ones were implemented sequentially over the next 4 years. These strategies include (1) a standardized feeding protocol, (2) early initiation of enteral feeding using human milk, (3) optimization of the osmolality of preterm milk feeds using standardized dilution guidelines for additives, and (4) promotion of healthy microbiome by use of probiotics, early oral care with colostrum and by restricting high-risk medications and prolonged use of empirical antibiotics RESULTS: Baseline characteristics of the patients including sex, gestational age, and birth weight were similar during the study period. After implementing the evidence-based practices successively over 4 years, the incidence of NEC in very- low birth-weight (VLBW) infants dropped from 7% in 2014 to 0% (P < .001) in 2018. The duration of parenteral nutrition, use of central line, and days to full feeds were also reduced significantly (P < .05) CONCLUSION: Adopting evidence-based best practices resulted in a significant decrease in the incidence of NEC and improved the nutrition outcomes in VLBW infants.

Epidemiology of Neonatal Septicemia in the Era of Extended Spectrum Beta-Lactamase Producing Bacteria: A Prospective Study in a Tertiary Referral Hospital. JOURNAL OF PURE AND APPLIED MICROBIOLOGY 2020.

Abstract
A surge of extended spectrum beta lactamase (ESBL)-producers is being witnessed in the neonatal intensive care units (NICUs). Hence, the present study was conducted to analyze both the bacteriological profile and clinical outcome of neonatal septicemia, and to identify the prevalence and sensitivity of the incriminated pathogens with emphasis on ESBL producers. We conducted this study in the NICU of a tertiary referral hospital over a one-year-period. All neonates with a clinical diagnosis of sepsis (371 participants) were enrolled. Blood cultures were performed, and subsequent cultures of various specimens were done according to clinical suspicion. Antibiotic susceptibility tests were carried out and the neonates were followed up until discharge. Out of the 371 neonates, 137 (37%) had positive blood culture results, of whom 49% died versus only 7.7% of neonates with a negative blood culture (P-value< 0.0001). Low birth weight, prematurity, and the duration of hospital stay were considered as positive blood culture risk factors. Meanwhile, among 85 cultures that yielded Gram-negative pathogens, 16 isolates were identified as ESBL producers with Klebsiella pneumoniae being the most frequently encountered isolate (19.7%). Of the neonates inflicted with ESBL-sepsis, 62.5% died versus 11.6% with non-ESBL sepsis. Judicious antibiotic stewardship together with infection control practices can hinder the spread of drug-resistant pathogens. This is especially compelling among the vulnerable population of the NICUs. Meanwhile, rapid diagnostic modalities and timely antibiotic susceptibility tests are of paramount importance to initiate appropriate therapy which can hugely impact the clinical prognosis.

Abstract
BACKGROUND Recently intravenous (IV) and aerosolized (ASZ) colistin have been used for treating ventilator-associated pneumonia (VAP) due to colistin susceptible multidrug-resistant Gram-negative bacteria (MDR-GNB). Colistin has limited lung penetration. We compared the efficacy and safety of IV-alone versus IV+ASZ-colistin for treating VAP in neonates. METHODS This retrospective matched case-control study was performed at NICU of the Aga Khan University Hospital, Pakistan between January 2015 and December 2018. Sixteen neonates with MDR-GNB associated VAP received IV-ASZ-colistin and were matched for date of birth, gestational age, birth weight, Apgar score, antenatal steroid history, disease severity, and duration of mechanical ventilation with 16 control neonates who received IV-colistin alone. RESULTS Both groups had similar MDR-GNB isolates and Acinetobacter baumannii (78%) was the most common pathogen. No colistin-resistant strain was isolated. Duration of IV-colistin and concomitant antibiotics use was significantly (p < 0.05) shorter in the IV-ASZ-colistin group. Significantly (p < 0.05) higher clinical cure and microbial eradication, along with lower ventilatory requirements, mortality rate, and colistin induced nephrotoxicity and electrolyte imbalance was observed in the IV-ASZ-colistin group. CONCLUSIONS With better lung penetration, ASZ-colistin offers effective and safe microbiological and clinical benefits as adjunctive or alternate treatment of VAP due to colistin susceptible MDR-GNB in neonates.

Abstract
BACKGROUND Neonatal sepsis remains one of the leading causes of mortality and morbidity in developing countries. With a dearth of data on neonatal sepsis in our country, this study was conducted to determine the incidence of clinical neonatal sepsis and evaluate the clinical, bacteriological, and antimicrobial susceptibility profile of organisms. Material and Methods. A prospective cross-sectional study was conducted in the Neonatal Unit of the National Hospital from 1st January to 31st December 2016. All neonates admitted with suspected clinical sepsis were included. Sepsis screens and cultures were sent under aseptic conditions. Data was analyzed using STATA™ version 12. Clinical features and neonatal and maternal risk factors were analyzed using chi-squared test. Bacteriological profile was analyzed with descriptive statistics. RESULTS During the study period, incidence of culture positive neonatal sepsis was 19 per 1000 admissions with a blood culture positivity rate of 14%. 54.5% had culture-positive early-onset sepsis (EOS). Prematurity (p = 0.012), APGAR < 6 (p = 0.018), low birth weight (p < 0.001), and maternal intrapartum antibiotics (p = 0.031) significantly increased risk for culture-positive EOS. Prematurity (p < 0.001), low birth weight (p = 0.001), and parental nutrition (p = 0.007) were significantly associated with increased risk of culture-positive late-onset sepsis. A positive screen had sensitivity of 81.8% and negative predictive value of 87.7%. Gram-negative organisms were most commonly isolated (64.6%). Coagulase-negative Staphylococci (31%) were the commonest isolate followed by Klebsiella pneumoniae (27%) and Acinetobacter (18.8%). Ninety percent of Acinetobacter were carbapenem resistant. Gram-negative sepsis had mortality of 88.9%. CONCLUSION Preterm, low birth weight, low APGAR scores, intrapartum antibiotics, and parental nutrition were significantly associated with neonatal sepsis. Coagulase-negative Staphylococci, Klebsiella pneumoniae, and Acinetobacter were the principal causative organisms. Gram-negative organisms had high resistance to commonly used antibiotics.

Abstract
BACKGROUND Despite remarkable progress in the reduction of death in under-five children, neonatal mortality has shown little or no concomitant reduction globally. It is also one of the most common causes of neonatal death in Ethiopia. Little is known on predictors of neonatal sepsis. Risk based screening and commencement of treatment appreciably reduces neonatal death and illness. Therefore, the main aim of this study was to identify predictors of neonatal sepsis in public referral hospitals of Northwest Ethiopia. METHODS Institutional based unmatched case-control study was conducted among a total of 231 neonates in Debre Markos and Felege Hiwot referral hospitals from March 2018- April 2018. Neonates who fulfill the preseted criteria for sepsis were considered as cases and neonates diagnosed with other medical reasons except sepsis were controls. For each case, two consecutive controls were selected by simple random sampling method. Data were collected using structured pretested questionnaire through a face to face interview with index mothers and by reviewing neonatal record using checklist. The collected data were entered into Epi data version 3.1 and exported to STATA/ SE software version 14. Binary and multivariable logistic regression analyses were employed. Statistical significance was declared at P<0.05. RESULT Multivariable logistic regression analysis showed that, duration of rupture of membrane ≥ 18hours was significantly associated with sepsis (AOR = 10.4, 95%CI = 2.3-46.5). The other independent predictors of neonatal sepsis were number of maternal antenatal care service ≤3 (AOR = 4.4, 95%CI = 1.7-11.5), meconium stained amniotic fluid (AOR = 3.9, 95%CI = 1.5-9.8), urinary tract infection during pregnancy (AOR = 10.8, 95% CI = 3.4-33.9), intranatal fever (AOR = 3.2, 95% CI = 1.1-9.5), first minute APGAR score <7 (AOR = 3.2, 95% CI = 1.3-7.7), resuscitation at birth (AOR = 5.4, 95% CI = 1.9-15.5), nasogastric tube insertion (AOR = 3.7, 95% CI = 1.4-10.2). CONCLUSION Neonatal invasive procedures, ANC follow up during pregnancy, different conditions during birth like meconium stained amniotic fluid, low APGAR score and resuscitation at birth were the independent predictors of neonatal sepsis.

Abstract
Background This study aimed to describe the causative organisms of neonatal late-onset sepsis (LOS) and their antimicrobial resistance in Suzhou, Southeast China over a 7-year period. Methods We performed a retrospective study on neonates with LOS from Jan1, 2011 to Dec 31, 2017. The demographic, clinical, and laboratory data of neonates with LOS were analyzed. Logistic regression was used to investigate the risk factors with mortality. Results During the study period, 202 neonates with LOS were finally identified. The most common pathogens were Escherichia coli (29.2%), followed by Klebsiella pneumoniae (19.3%), and Coagulase-negative Staphylococcus (CoNS) (16.8%). Nearly 90% of the K. pneumoniae were resistant to cefazolin and 71.8% to ceftazidime. Thirty-four patients (16.8%) died. Multivariable logistic regression showed that significant predictors of mortality were birth weight < 1500 g, respiratory distress and convulsions. Conclusions Gram-negative organisms have an important role in LOS in our region, with high levels of resistance to third-generation cephalosporins. These data may help in the selection of antibiotics for empirical treatment of neonates with sepsis.

Abstract
Late-onset sepsis (LOS) and other systemic bloodstream infections are notable causes of neonatal mortality, particularly in prematurely born very low birth weight infants. Breastfeeding in early life has numerous health benefits, impacting the health of the newborn in both the short-term and in the long-term. Though the known benefits of an exclusive mother's own milk diet in early life have been well recognized and described, it is less understood how breastfed infants enjoy a potential reduction in risk of LOS and other systemic infections. Here we review how gut residing pathogens within the intestinal microbiota of infants can cause a subset of sepsis cases and the components of breastmilk that may prevent the dissemination of pathogens from the intestine.

Abstract
BACKGROUND/PURPOSE Rapid and accurate identification of pathogens and their antibiotic resistance directly from flagged blood cultures can aid clinicians in optimizing early antibiotic treatment and improve the clinical outcomes, especially in settings associated with high rates of bloodstream infection caused by vancomycin-resistant Enterococci (VRE) and carbapenem-resistant Enterobacteriaceae (CRE). We compared the results of the BioFire FilmArray Blood Culture Identification (BCID) panel with those of conventional methods for identifying the pathogens and their antibiotic susceptibility status. METHODS In total, 100 randomly selected positive blood cultures (BACTEC Plus Aerobic/F bottles or BACTEC Anaerobic Lytic/10 bottles) were analyzed. The pathogen detection efficiency of FilmArray BCID panel was compared with that of conventional method using MALDI-TOF MS system (Bruker MALDI Biotyper) and susceptibility testing by the Vitek 2 system. The sequencing analysis of antibiotic resistance genes was performed for discrepant results obtained from MALDI Biotyper and Vitek 2. RESULTS Among the 100 positively flagged blood cultures, 94% of FilmArray BCID panel results were consistent with the MALDI Biotyper results. All five VRE isolates positive for vanA/vanB genes, 10 of 12 Staphylococcus species positive for mecA gene, and only one Klebsiella pneumoniae isolate positive for K. pneumoniae carbapenemase gene (blaKPC) detected in the FilmArray BCID panel were also concordant with results by the results by conventional susceptibility testing/molecular confirmation. CONCLUSIONS The FilmArray BCID panel results not only demonstrated good correlation with conventional blood culture identification and susceptibility results but also provided results rapidly, especially for the early detection of MRSA, VRE and blaKPC-mediated CRE.

Abstract
Purpose To determine the bacteriological pattern and antibiotic susceptibility of bacterial isolates causing neonatal sepsis in Qena University Hospitals and compare polymerase chain reaction (PCR) and blood culture results in a trial for rapid diagnosis. Patients and methods Blood samples from 75 clinically suspected cases of neonatal sepsis were subjected to identification of bacteria and determination of their antibiotic sensitivity through blood culture, and rapid detection of 16S rRNA and the uidA gene (to confirm the presence of E. coli) by PCR from extracted bacterial DNA. Results Most patients were preterm (64%) and low birth weight (LBW) (68%). In total, 42.7% presented with early onset sepsis (EOS). LBW was significantly associated with EOS (P-value=0.03). Although the blood culture and PCR results were similar in EOS, the PCR results were significantly higher than those of blood culture in detecting bacteria (85.3% vs 68%, respectively, P-value=0.001). Blood culture showed 100% specificity. The most common pathogen was E. coli (86.2%) in EOS and Staphylococcus spp. (45.5%) in late-onset sepsis (LOS) (P-value=0.001 and 0.02, respectively). The most effective antibiotics against Gram-negative bacteria were ofloxacin, ciprofloxacin, imipenem, and amikacin, while vancomycin, oxacillin, and imipenem were the most effective antibiotics against Gram-positive bacteria. Conclusion EOS was mainly caused by E. coli, while LOS was mainly caused by Staphylococcus spp. The 16S rRNA PCR showed higher sensitivity with rapid and accurate diagnosis. Blood culture is the most suitable method for antimicrobial sensitivity testing.

Abstract
OBJECTIVE To compare demographic and clinical features of neonates with late-onset sepsis due to coagulase-negative-staphylococcus with those due to other bacterial pathogens. STUDY DESIGN Retrospective, population-based cohort study. Data on infants less than 90 days old diagnosed with late-onset bacterial sepsis in the neonatal intensive care unit were reviewed. Univariable and multivariable analysis were performed. RESULTS Two hundred and sixteen sepsis episodes were identified: coagulase-negative-staphylococcus caused 113 (52.3%) and other pathogen 103 (47.7%). Patients with coagulase-negative-staphylococcus sepsis had lower gestational age and younger age at onset, higher rates of parenteral nutrition exposure and normal temperature, lower rates of necrotizing enterocolitis, meningitis and neutropenia than patients with sepsis caused by other pathogens. In multivariable analysis, parenteral nutrition was the only independent risk factor for coagulase-negative-staphylococcus sepsis (odds ratio: 3.5, 95% confidence interval: 1.4-8.6). CONCLUSIONS Initial empiric treatment for suspected sepsis should be targeted for other pathogens than coagulase-negative-staphylococci and vancomycin treatment should be reserved for infants with specific risk factors and according to local antimicrobial susceptibility.

Abstract
Neonatal sepsis still represents an important cause of mortality and morbidity among infants. According to the onset, we can distinguish "early onset sepsis" when microbiological cultures positive for external pathogens come from newborns during the first 7 days of life (maternal intrapartum transmission); "late onset sepsis" when microbiological cultures positive for external pathogens come from newborns after the first 7 days from delivery (postnatal acquisition). In this review we synthesize the incidence, risk factors, clinical manifestations, and methods of diagnosis and treatment of each type of neonatal infection, in order to better define such a pathological condition which is of great importance in common clinical practice.
