Kuitunen I, Kekki M, Renko M. Intrapartum azithromycin to prevent maternal and neonatal sepsis and deaths: A systematic review with meta-analysis. BJOG 2024; 131:246-255. [PMID: 37691261 DOI: 10.1111/1471-0528.17655] [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: 06/13/2023] [Revised: 08/12/2023] [Accepted: 08/18/2023] [Indexed: 09/12/2023]
Abstract
OBJECTIVES A systematic review with met-analysis was performed to summarise the evidence on the effect of intrapartum azithromycin on maternal and neonatal infections and deaths. SEARCH STRATEGY PubMed, Scopus and Web of Science databases were searched in March 2023. SELECTION CRITERIA Randomised controlled trials comparing intrapartum single-dose of azithromycin with placebo. DATA COLLECTION AND ANALYSIS Maternal infections, maternal mortality, neonatal sepsis, neonatal mortality. We used the random-effects Mantel-Haenszel method to calculate risk ratios (RR) with 95% confidence intervals (95% CI). We assessed risk of bias of the included studies and estimated the evidence certainty using the GRADE approach. MAIN RESULTS After screening 410 abstracts, five studies with 44 190 women and 44 565 neonates were included. The risk of bias was low in four and had some concerns in one of the studies. The risk of endometritis was 1.5% in the azithromycin group and 2.3% in the placebo group (RR 0.64, 95% CI 0.55-0.75), and the evidence certainty was high. The respective risk for chorioamnionitis was 0.05% and 0.1% (RR 0.50, 95% CI 0.22-1.18; evidence certainty moderate). The wound infection rate was lower in the azithromycin group (1.6%) than in the placebo group (2.5%), RR 0.52 (95% CI 0.30-0.89; moderate certainty evidence). The maternal sepsis rate was 1.1% in the azithromycin group and 1.7% in the placebo group (RR 0.66, 95% CI 0.56-0.77; evidence certainty high). Mortality rates did not show evidence of a difference (0.09% versus 0.08%; RR 1.26, 95% CI 0.65-2.42; moderate certainty evidence). The neonatal mortality rate was 0.7% in the azithromycin group and 0.8% in the placebo group (RR 0.94, 95% CI 0.76-1.16; moderate certainty evidence). The neonatal sepsis rate was 7.6% in the azithromycin group and 7.4% in the placebo group (RR 1.02, 95% CI 0.96-1.09; moderate certainty evidence). CONCLUSIONS Intrapartum administration of azithromycin to the mother reduces maternal postpartum infections, including sepsis. Impact on maternal mortality remains undecided. Azithromycin does not reduce neonatal sepsis or mortality rates.

Abstract
BACKGROUND Screening-based and risk-based strategies are the 2 strategies for preventing group B streptococcus (GBS) diseases in neonates. We aimed to compare the effects of these 2 strategies in reducing the incidence of early-onset GBS sepsis (GBS-EOS) and their effects on the incidence of non-GBS sepsis. METHODS PubMed, Embase, Web of Science and The Cochrane Central Register of Controlled Trials were searched for the period from January 1, 1996, to December 31, 2018. Randomized controlled trials and cohort studies that compared the effects of risk-based and screening-based strategies were eligible for the meta-analysis. The I statistic was used for assessing the statistical heterogeneity across studies. Pooled relative risks (RRs) and corresponding 95% confidence intervals (CIs) were calculated using the random effects model. RESULTS There were 18 cohort studies comparing the incidence of GBS-EOS between the 2 strategies, involving a total of 604,869 newborns and 791 GBS-EOS cases. The heterogeneity across studies was moderate (I = 45%), and the pooled analysis yielded a 55% decreased risk of GBS-EOS for screening-based versus risk-based strategy (RR = 0.45; 95% CI: 0.34-0.59). For total early onset non-GBS sepsis (non-GBS-EOS), 7 studies with low heterogeneity (I = 18%) had a pooled RR of 0.91 (95% CI: 0.74-1.11), whereas for ampicillin resistant Escherichia coli-EOS, a subgroup of non-GBS-EOS, 3 studies with very low heterogeneity (I = 0%) had a pooled RR of 1.28 (95% CI: 0.74-2.21) for screening-based strategy compared with risk-based strategy. CONCLUSIONS Compared with risk-based strategy, screening-based prophylaxis was associated with a reduced risk of GBS-EOS.

Abstract
BACKGROUND Early-onset group B streptococcal (EOGBS) disease (including sepsis, meningitis, and pneumonia) causes significant morbidity and mortality in newborn infants worldwide. Antibiotic prophylaxis can prevent vertical streptococcal transmission, yet no uniform criteria exist to identify eligible women for prophylaxis. Some guidelines recommend universal GBS screening to pregnant women in their third trimester (screening-based protocol), whereas others employ risk-based protocols. OBJECTIVES To compare the effectiveness of screening-based versus risk-based protocols in preventing EOGBS disease. SEARCH STRATEGY Key words for the database searches included GBS, Streptococcus agalactiae, pregnancy, screening, culture-based, risk-based. SELECTION CRITERIA Studies were included if they investigated EOGBS disease incidence in newborn infants and compared screening or risk-based protocols with each other or with controls. DATA COLLECTION AND ANALYSIS Risk ratios (RR) and 95% confidence intervals (CI) were determined using Mantel-Haenszel analyses with random effects. MAIN RESULTS Seventeen eligible studies were included. In this meta-analysis, screening was associated with a reduced risk for EOGBS disease compared either with risk-based protocols (ten studies, RR 0.43, 95% CI 0.32-0.56) or with no policy (four studies, RR 0.31, 95% CI 0.11-0.84). Meta-analysis could not demonstrate a significant effect of risk-based protocols versus no policy (seven studies, RR 0.86, 95% CI 0.61-1.20). In studies reporting on the use of antibiotics, screening was not associated with higher antibiotic administration rates (31 versus 29%). CONCLUSIONS Screening-based protocols were associated with lower incidences of EOGBS disease compared with risk-based protocols, while not clearly overexposing women to antibiotics. This information is of relevance for future policymaking. TWEETABLE ABSTRACT Meta-analysis: general screening is associated with lower rates of early-onset group B strep. neonatal sepsis compared with risk-based protocols.

Abstract
BACKGROUND The epidemiology of early-onset neonatal sepsis (EONS) varies over time, and requires regular surveillance. OBJECTIVE To analyse data on EONS in Australia and New Zealand. METHODS Retrospective analysis of data collected longitudinally from multiple neonatal units from 2002 to 2012. RESULTS Of 386 423 live births, 454 infants had EONS. The incidence rate of EONS was 1.20 per 1000 live births in 2002 and 0.83 in 2012, decreasing by 4% per year (95% CI 1% to 7%, p=0.007). Group B streptococcus (GBS) (37%) and Escherichia coli (25%) were the most prevalent organisms. The early-onset GBS (EOGBS) incidence rate was 0.43/1000 live births, with no evidence of change over time (p=0.3). Of EOGBS-infected babies, 62% were born at term compared with 8% with early-onset E. coli sepsis, p<0.0001. The mortality of E. coli early-onset sepsis (EOS) (25%) was higher than GBS (11%), but this difference in mortality was no longer significant after adjusting for gestation and birth weight. Mortality from EOS fell significantly over the study period (17% per year, 95% CI 10 to 24, p<0.0001). CONCLUSIONS GBS was the most common cause of early sepsis, but the incidence was lower than prior to the introduction of intrapartum antibiotic prophylaxis, and remained steady over time. The mortality of early-onset E. coli sepsis was significantly higher than GBS sepsis, but this may have been because almost all babies with E. coli were born preterm, rather than a difference in virulence.

Abstract
Purpose In this study, we investigated the clinical features and prognostic factors of early-onset sepsis (EOS) in neonatal intensive care unit (NICU) patients. Methods A retrospective analysis was conducted on medical records from January 2010 to June 2017 (7.5 years) of a university hospital NICU. Results There were 45 cases of EOS (1.2%) in 3,862 infants. The most common pathogen responsible for EOS was group B Streptococcus (GBS), implicated in 10 cases (22.2%), followed by Escherichia coli, implicated in 9 cases (20%). The frequency of gram-positive sepsis was higher in term than in preterm infants, whereas the rate of gram-negative infection was higher in preterm than in term infants (P<0.05). The overall mortality was 37.8% (17 of 45), and 47% of deaths occurred within the first 3 days of infection. There were significant differences in terms of gestational age (26.8 weeks vs. 35.1 weeks) and birth weight (957 g vs. 2,520 g) between the death and survival groups. After adjustments based on the difference in gestational age and birth weight between the 2 groups, gram-negative pathogens (odds ratio [OR], 42; 95% confidence interval [CI], 1.4–1,281.8) and some clinical findings, such as neutropenia (OR, 46; 95% CI, 1.3–1,628.7) and decreased activity (OR, 34; 95% CI, 1.8–633.4), were found to be associated with fatality. Conclusion The common pathogens found to be responsible for EOS in NICU patients are GBS and E. coli. Gram-negative bacterial infections, decreased activity in the early phase of infection, and neutropenia were associated with poor outcomes.

Abstract
Background: Early onset sepsis (EOS) is potentially life-threatening problem especially in preterm. EOS diagnosis is challenging due to its non-specific signs and laboratory tests. Mean platelet volume (MPV) has been used as predictor of many inflammatory diseases.Objectives: To assess the correlation between serial MPV measurement and EOS occurrence in preterm infants and to determine MPV effectiveness in combination with C reactive protein (CRP) to diagnose EOS and mortality prediction.Methods: The study was carried out on 95 preterm infants with antenatal risk factor for EOS. Blood samples were taken for complete blood count (CBC) including MPV evaluated at birth (cord blood) and at 72 h of life. CRP analyzed on days 1 and 3, subsequently patients were identified in two groups: sepsis (n = 28) and no-sepsis (n = 67).Results: MPV was significantly higher on both day 1 (10.23 ± 0.92) fl and day 3 (10.77 ± 1.16) fL in the sepsis group compared with no-sepsis (8.11 ± 0.29) fl and (8.53 ± 0.42) fl, respectively. MPV of 8.6 fL was identified as cut off value in patients probably resulting in sepsis with a sensitivity of 97.14% and a specificity of 100%. MPV of 10.4 fl was determined as cut off value in patients possibly resulting in death with a sensitivity of 70% and a specificity of 82.5%. The combination of both MPV and CRP on day 1 resulted in improving performance of MPV with higher negative predictive value (93.1%) and higher sensitivity (80%).Conclusion: High cord blood and day 3 MPV can be used as surrogate marker for prediction of EOS and associated mortality in preterm neonates.

Abstract
AIM To reduce the intrapartum use of antibiotics in women with prolonged rupture of the membranes (PROM) by restriction of antibiotics to women who are colonized with group B streptococci (GBS), as identified with the Cepheid Gene Xpert polymerase chain reaction (PCR) for detecting GBS. METHODS We conducted a randomized controlled trial among full-term delivering women with PROM. Fifty-four women were enrolled, based on a power calculation with a significance level of 5% and a power of 95%. Twenty-seven women received the standard treatment (rectovaginal swab [RVS] for bacterial culture and antibiotics). For another 27 women PCR was performed on the RVS and antibiotics were used only when the PCR was positive. The primary outcome was reduction in antibiotic use, defined as the percentage of women who received antibiotics during labor. RESULTS 54 Women were enrolled in the study between 1 May and 18 November 2014. There were no significant differences in baseline characteristics. In total, 10 of the 54 women were GBS positive (18.5%). Of those 10 women, three were identified on bacterial culture and seven on PCR. In the bacterial culture group all the women received antibiotics. In the PCR group 10 women (37%) received antibiotics (P = 0.002). Two false-positive PCR tests were identified. There were no false-negative PCR tests. CONCLUSION Real-time identification of GBS on PCR reduces the intrapartum use of antibiotics in women with PROM.

Abstract
BACKGROUND Antibiotic resistance is a worldwide problem. We describe 25 years of responsible antibiotic use in a tertiary neonatal unit. METHODS Data on neonatal infections and antibiotic use were collected prospectively from 1990 to 2014 at a single tertiary Sydney neonatal intensive care unit attached to a maternity unit. There are approximately 5500 deliveries and 900 nursery admissions per year. RESULTS The mean annual rate of late-onset sepsis was 1.64 episodes per 100 admissions. The mean number of late-onset sepsis episodes per admission to the neonatal unit decreased by 4.0% per year (95% CI 2.6% to 5.4%; p<0.0001) and occurred particularly in infants born weighing <1500 g. No infants with negative cultures relapsed with sepsis when antibiotics were stopped after 48-72 hours. Antibiotic use decreased with time. The proportion of colonising methicillin-resistant Staphylococcus aureus isolates decreased by 7.4% per year (95% CI 0.2% to 14.1%; p=0.043). The proportion of colonising Gram-negative bacilli isolates resistant to either third-generation cephalosporins or gentamicin increased by 2.9% per year (95% CI 1.0% to 4.9%; p=0.0035). Most were cephalosporin-resistant; gentamicin resistance was rare. An average of one baby per year died from late-onset sepsis, the rate not varying significantly over time. The mortality from episodes of late-onset sepsis was 25 of 332 (7.5%). CONCLUSION Stopping antibiotics after 2-3 days if neonatal systemic cultures are negative is safe. However, it does not prevent the emergence of cephalosporin-resistant Gram-negative organisms.

Abstract
OBJECTIVES To decrease the incidence of early-onset group B streptococcal (GBS) disease, a culture-based screening of all pregnant women at 35-37 weeks is recommended. This gold standard test requires 24-72hours culture. This delay precludes its use for intrapartum screening. This study assesses a new immunoassay, the DIMA test, for identifying GBS-positive patients in the labor ward. MATERIALS AND METHODS This was a prospective observational study of 195 pregnant women presenting with full-term labor at a single site in France between June and August 2012. We assessed the diagnostic accuracy of intrapartum DIMA testing as compared to intrapartum GBS culture and prenatal screening at 35-38 weeks. RESULTS The DIMA test sensitivity and specificity were 57.1% and 83.2%, respectively, as compared to 42.9% and 97% for prenatal culture screening. CONCLUSION The DIMA test assay is a rapid and inexpensive test for the detection of maternal GBS colonization in the labor ward. Its sensitivity is higher than antepartum culture but its specificity is lower. Its performance was inferior to that reported for rapid polymerase chain reaction assays.

Abstract
In the past century, advances in antibiotics and vaccination have dramatically altered the incidence and clinical outcomes of bacterial meningitis. We review the shifting epidemiology of meningitis in children, including after the implementation of vaccines that target common meningitic pathogens and the introduction of intrapartum antibiotic prophylaxis offered to mothers colonized with
Streptococcus agalactiae. We also discuss what is currently known about the pathogenesis of meningitis. Recent studies of the human microbiome have illustrated dynamic relationships of bacterial and viral populations with the host, which may potentiate the risk of bacterial meningitis.

Abstract
Background The objective of this study was to explore the prevalence of microbiological contamination of mobile phones that belong to clinicians in intensive care units (ICUs), pediatric intensive care units (PICUs), and neonatal care units (NCUs) in all public secondary care hospitals in Kuwait. The study also aimed to describe mobile phones disinfection practices as well as factors associated with mobile phone contamination. Methods This is a cross-sectional study that included all clinicians with mobile phones in ICUs, PICUs, and NCUs in all secondary care hospitals in Kuwait. Samples for culture were collected from mobile phones and transported for microbiological identification using standard laboratory methods. Self-administered questionnaire was used to gather data on mobile phones disinfection practices. Results Out of 213 mobile phones, 157 (73.7 %, 95 % CI [67.2–79.5 %]) were colonized. Coagulase-negative staphylococci followed by Micrococcus were predominantly isolated from the mobile phones; 62.9 % and 28.6 % of all mobile phones, respectively. Methicillin-resistant Staphylococcus aureus (MRSA) and Gram-negative bacteria were identified in 1.4 % and 7.0 % of the mobile phones, respectively. Sixty-eight clinicians (33.5 %) reported that they disinfected their mobile phones, with the majority disinfecting their mobile phones only when they get dirty. The only factor that was significantly associated with mobile phone contamination was whether a clinician has ever disinfected his/her mobile phone; adjusted odds ratio 2.42 (95 % CI [1.08–5.41], p-value = 0.031). Conclusion The prevalence of mobile phone contamination is high in ICUs, PICUs, and NCUs in public secondary care hospitals in Kuwait. Although some of the isolated organisms can be considered non-pathogenic, various reports described their potential harm particularly among patients in ICU and NCU settings. Isolation of MRSA and Gram-negative bacteria from mobile phones of clinicians treating patients in high-risk healthcare settings is of a major concern, and calls for efforts to consider guidelines for mobile phone disinfection.

ACTA ACUST UNITED AC 2015; 13:206-46. [PMID: 26447057 DOI: 10.11124/jbisrir-2015-1876] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2014] [Revised: 02/20/2015] [Accepted: 03/02/2015] [Indexed: 10/31/2022]
Abstract
BACKGROUND Early-onset group B streptococcus disease, recognized as the most common cause of early onset neonatal sepsis in developed countries, is transmitted vertically from the group B streptococcus carrier mother to the neonate in the peripartum. Accordingly, early-onset group B streptococcus disease is prevented by halting the transmission of the microorganism from the mother to the infant. Two main methods, routine culture-based screening and risk-based management, may be used in the identification of mothers requiring intrapartum antibiotic prophylaxis in labor. While there are advantages and disadvantages to each, there is limited high level evidence available as to which method is superior. OBJECTIVES To identify the effectiveness of risk-based management versus routine culture-based screening in the prevention of early-onset group B streptococcus disease in the neonate. INCLUSION CRITERIA TYPES OF PARTICIPANTS This review considered studies which treated pregnant women with intrapartum antibiotic prophylaxis following risk- and culture-based protocols for the prevention of early-onset group B streptococcus disease in the neonate. Types of intervention: This review considered studies that evaluated risk-based management against routine culture-based screening for the prevention of early-onset group B streptococcus disease in the neonate. Types of studies: This review looked for highest evidence available which in this case consisted of one quasi experimental study and eight comparative cohort studies with historical or concurrent control groups. Types of outcomes: Incidence of early-onset group B streptococcus disease in neonates as measured by positive group B streptococcus culture from an otherwise sterile site. Secondary outcomes include neonatal death due to group B streptococcus sepsis and percentage of women who received intrapartum antibiotic prophylaxis. SEARCH STRATEGY A multi-step search strategy was used to find studies which were limited to the English language and published between January 2000 and June 2013. METHODOLOGICAL QUALITY The quality of the eligible studies was assessed independently by two reviewers using the Joanna Briggs Institute quality assessment tool for observational studies. DATA COLLECTION Data was extracted using a standardized extraction tool from the Joanna Briggs Institute. DATA SYNTHESIS Quantitative papers were, where possible, pooled for meta-analysis using Joanna Briggs Institute Meta Analysis of Statistics Assessment and Review Instrument effect sizes expressed as odds ratio and their 95% confidence intervals were calculated. Heterogeneity was assessed statistically using the standard Chi-square. RESULTS The results of this review come from nine studies published in peer reviewed journals. The treatment group consists of those screened as per the culture-based protocol, the control group the risk-based protocol. For combined term and preterm infants the odds of early-onset group B streptococcus disease for the treatment vs control groups is 0.45 (95% CI 0.37 to 0.53). The odds ratio in term infants is 0.45 (95% CI 0.36 to 0.57). Preterm infants are four times (OR 4.20 [95% CI 3.36 to 5.24]) more likely to develop early-onset group B streptococcus disease than term infants regardless of prevention technique. One study provides information on neonatal mortality in which there is one neonatal death in the risk-based cohort and none in the culture-based. The TRUNCATED AT 500 WORDS.

Abstract
Although pregnancy is considered as a physiological state, most pregnant women in developed countries receive multiple medications to prevent maternal or neonatal complications, with antibiotics among the most frequently prescribed. During pregnancy, antibiotics are often prescribed in the context of preterm labor, intrapartum fever, prevention of neonatal Group B Streptococcus fever, and cesarean section. Outside this period, they are commonly prescribed in the community setting for respiratory, urinary, and ear, nose and throat infection symptoms. Whereas some of the current indications have insightful reasons to justify their use, potential risks related to overuse and misuse may surpass the benefits. Of note, the recent 2014 World Health Assembly expressed serious concern regarding antibiotic resistance due to antibiotic overuse and misuse and urged immediate action to combat antibiotic resistance on a global scale. Most studies in the obstetrics field have focused on the benefits of antibiotics for short-term maternal and neonatal complications, but with very little (if any) interest in long-term consequences.

Abstract
Group B streptococci (GBS) are a leading cause of infectious neonatal morbidity and mortality. Timely and accurate identification of colonized pregnant women is imperative to implement intrapartum antibioprophylaxis (IAP) to reduce the risk of early neonatal sepsis. Current guidelines recommend screening for GBS carriage with vaginal-rectal cultures. However, cultures require 24-72 h, thus precluding their use for intrapartum screening and these are only performed at 35-37 weeks gestation. New rapid molecular-based tests can detect GBS within hours. They have the potential to be used intrapartum and to allow for selective IAP in women carrying GBS. An advantage is that they can sometimes be performed by non-laboratory staff in the labor suite, thus avoiding delays in sample transfers to the microbiology laboratory. Another possible use of molecular-based assays is for the diagnosis of neonatal sepsis, where tests with a short turnaround time and high sensitivity and specificity are crucial. In this situation, the detection of microorganisms once antibiotic therapy has already been started is important, as treatment is started immediately once sepsis is suspected without waiting for microbiological confirmation. In this article, we discuss the state-of-the-art molecular-based tests available for GBS screening during pregnancy, as well as their implications for IAP for the diagnosis and prevention of neonatal sepsis.

Abstract
Background Prophylactic antibiotics reduce infectious morbidity from caesarean section. The timing of their administration, however, is a matter of controversy. Objectives To examine maternal and neonatal infectious morbidity in women receiving preoperative prophylaxis compared with those receiving intraoperative administration. Search strategy Medline, Embase, Current Controlled Trials and Cochrane Central were searched from their inception dates to December 2011. Selection criteria Randomised controlled trials of a single dose of any antibiotic comparing preoperative with intraoperative administration were selected. Data collection and analysis Trial characteristics, outcomes and quality measures, based on the Cochrane tool for risk of bias, were independently extracted. The random effect model of DerSimonian and Laird to estimate relative risks (RRs) for maternal and neonatal outcomes was used. Main results Six trials met the inclusion criteria, reporting on 2313 women and 2345 newborns. Preoperative administration was associated with a significant 41% reduction in the rate of endometritis compared with intraoperative administration (RR 0.59; 95% confidence interval [95% CI] 0.37–0.94; I2 0%). In the preoperative group, there were nonsignificant reductions in the rates of wound infection (RR 0.71; 95% CI 0.44–1.14; I2 0%), maternal febrile morbidity (RR 0.94; 95% CI 0.46–1.95; I2 0%), neonatal sepsis (RR 0.81; 95% CI 0.47–1.41; I2 0%), neonatal septic work-up (RR 0.93; 95% CI 0.71–1.21; I2 0%) and neonatal intensive-care unit admission (RR 0.92; 95% CI 0.65–1.28; I2 0%). There were nonsignificant increases in the rates of maternal pyelonephritis (RR 1.09; 95% CI 0.49–2.43; I2 0%) and neonatal pneumonia (RR 3.36; 95% CI 0.55–20.47; I2 0%). Conclusions Compared with intraoperative administration, preoperative antibiotics significantly reduce the rate of endometritis. The lack of neonatal adverse effects should be cautiously interpreted given the limited power of the trials to detect such effects.

Abstract
OBJECTIVE Organisms causing early-onset neonatal sepsis (EONS) have consistently changed over time. The distribution of organisms in EONS helps to influence the appropriate type of antibiotic prophylaxis strategy during labor and the antibiotics used in neonates with suspected sepsis. STUDY DESIGN To compare the organisms distribution for EONS between 2003 and 2008 for infants admitted to neonatal intensive care units (NICUs) in Canada. Data were retrieved from infants with a positive bacterial blood or cerebrospinal fluid culture in the first 72 h after birth who were admitted to NICUs participating in the Canadian Neonatal Network from 2003 to 2008. Comparisons of incidence rate, demographics and causative organisms were carried out between earlier cohort (2003 to 2005) and later cohort (2006 to 2008). RESULT A total of 405 infants had positive blood and/or cerebral spinal fluid cultures over the study period. The EONS rate was 6.8/1000 admissions (n=24969) in the earlier cohort compared with 6.2/1000 admissions (n=37484) in the later cohort (P=0.36). Rate of clinical chorioamnionitis was higher in the later cohort (38 vs 26%; P=0.02). For term infants, coagulase-negative Staphylococcus (CONS) (2.4/1000) followed by group B Streptococcus (GBS) (1.9/1000) were the most common organisms identified. For preterm infants, CONS (2.5/1000) followed by Escherichia coli (2.6/1000) were the most common organisms identified. There was a significant reduction in GBS EONS over time (P<0.01) and a trend toward an increase in other organisms. CONCLUSION Although the rate of EONS among neonates admitted to NICUs has not changed, the pattern of infection has changed over the past 6 years. With the increased use of prophylactic antibiotics to mothers, careful surveillance of the changing trend of bacterial organisms among neonates is warranted.

Abstract
Infections are a major cause of neonatal death in developing countries. High-quality information on the burden of early-onset neonatal sepsis and sepsis-related deaths is limited in most of these settings. Simple preventive and treatment strategies have the potential to save many newborns from sepsis-related death. Implementation of public health programs targeting newborn health will assist attainment of Millennium Development Goals of reduction in child mortality.

Abstract
The burden of early-onset disease caused by group B Streptococcus (GBS) has decreased dramatically in the United States over the past 20 years. Universal culture-based screening at 35 to 37 weeks gestational age and use of intrapartum antibiotic prophylaxis are the cornerstones of prevention measures that have led to this decline. GBS, however, remains the leading cause of early-onset neonatal sepsis in the United States. Revised guidelines for prevention of perinatal GBS are planned for issuance in 2010. This article discusses implementation challenges for clinicians caring for pregnant women and newborns and presents an updated algorithm for neonatal management.

Abstract
OBJECTIVE The goal was to evaluate risk factors for invasive Escherichia coli infections in the first week of life (early onset), focusing on the role of intrapartum antibiotic use. METHODS We conducted a retrospective case-control study. Between 1997 and 2001, case infants, defined as infants < 7 days of age with E coli isolated from blood or cerebrospinal fluid, were identified in selected counties of California, Georgia, and Connecticut by the Active Bacterial Core Surveillance/Emerging Infections Program Network. Control infants (N = 1212) were identified from a labor and delivery record review of a stratified random sample of live births at the same hospitals in 1998 and 1999. RESULTS Surveillance identified 132 E coli cases, including 68 ampicillin-resistant cases. The case fatality rate was 16% (21 of 132 cases). Two thirds of case infants were preterm, and 49% (64 of 132 infants) were born at < or = 33 weeks of gestation. Fifty-three percent of case mothers (70 of 132 mothers) received intrapartum antibiotic therapy; 70% of those received ampicillin or penicillin. Low gestational age (< or = 33 weeks), intrapartum fever, and membrane rupture of > or = 18 hours were associated with increased odds of early-onset E coli infection. Results were similar when case subjects were limited to those infected with ampicillin-resistant strains. Exposure to any intrapartum antibiotic treatment, beta-lactam antibiotic treatment, or > or = 4 hours of intrapartum antibiotic therapy was associated with increased odds of E coli infection and ampicillin-resistant infection in univariate analyses. Among preterm infants, intrapartum antibiotic exposure did not remain associated with either outcome in multivariable models. Among term infants, exposure to > or = 4 hours of intrapartum antibiotic therapy was associated with decreased odds of early-onset E coli infection. CONCLUSIONS Exposure to intrapartum antibiotic therapy did not increase the odds of invasive, early-onset E coli infection. Intrapartum antibiotic therapy was effective in preventing E coli infection only among term infants.

Abstract
Nine premature infants developed early onset sepsis and/or pneumonia with Haemophilus influenzae during a period of 53 months (January 2000 -May 2004). Their respiratory problems were pneumonia-like rather than classic respiratory distress syndrome. In 8 of the cases, the pathogen was a beta-lactamase-negative, nontypable H. influenzae. In the remaining case, the Haemophilus identified was type d. Before January 2000, no case of beta-lactamase-negative, nontypable H. influenzae sepsis or pneumonia had been recorded.
