Cerebral Oximetry Monitoring in Extremely Preterm Infants.

BACKGROUND: The use of cerebral oximetry monitoring in the care of extremely preterm infants is increasing. However, evidence that its use improves clinical outcomes is lacking. METHODS: In this randomized, phase 3 trial conducted at 70 sites in 17 countries, we assigned extremely preterm infants (gestational age, <28 weeks), within 6 hours after birth, to receive treatment guided by cerebral oximetry monitoring for the first 72 hours after birth or to receive usual care. The primary outcome was a composite of death or severe brain injury on cerebral ultrasonography at 36 weeks' postmenstrual age. Serious adverse events that were assessed were death, severe brain injury, bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and late-onset sepsis. RESULTS: A total of 1601 infants underwent randomization and 1579 (98.6%) were evaluated for the primary outcome. At 36 weeks' postmenstrual age, death or severe brain injury had occurred in 272 of 772 infants (35.2%) in the cerebral oximetry group, as compared with 274 of 807 infants (34.0%) in the usual-care group (relative risk with cerebral oximetry, 1.03; 95% confidence interval, 0.90 to 1.18; P = 0.64). The incidence of serious adverse events did not differ between the two groups. CONCLUSIONS: In extremely preterm infants, treatment guided by cerebral oximetry monitoring for the first 72 hours after birth was not associated with a lower incidence of death or severe brain injury at 36 weeks' postmenstrual age than usual care.

The association between maternal colonization with Group B Streptococcus and infectious morbidity following transcervical Foley catheter-assisted labor induction.

OBJECTIVES: To determine whether maternal colonization with Group B Streptococcus increases the risk for infectious morbidity following transcervical Foley catheter-assisted cervical ripening. METHODS: A retrospective cohort study comparing infectious morbidity and other clinical outcomes by Group B Streptococcus colonization status between all women with singleton pregnancies who underwent Foley catheter-assisted cervical ripening labor induction at a single tertiary medical center during 2011-2021. Multivariable logistic regression explored the relationship between Group B Streptococcus colonization to adverse outcomes while adjusting for relevant clinical variables. RESULTS: A total of 4,409 women were included of whom 886 (20.1 %) were considered Group B Streptococcus carriers and 3,523 (79.9 %) were not. Suspected neonatal sepsis rate was similar between Group B Streptococcus carriers and non-carriers (5.2 vs. 5.0 %, respectively, p=0.78). Neonatal sepsis was confirmed in 7 (0.02 %) cases, all born to non-carriers. Group B Streptococcus carriers had a higher rate of maternal bacteremia compared to non-carriers (1.2 vs. 0.5 %, respectively, p=0.01). Group B Streptococcus colonization was independently associated with maternal bacteremia (adjusted odds ratio 3.05; 95 %CI 1.39, 6.66). CONCLUSIONS: Group B Streptococcus colonization among women undergoing Foley catheter-assisted cervical ripening does not seem to increase the risk for neonatal infection. However, higher rates of maternal bacteremia were detected.

Prevalence and antibiotic resistance pattern of bacteria from sepsis suspected neonates at St. Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia.

BACKGROUND: Neonatal sepsis is the major cause of neonatal mortality and morbidity, especially in low and middle-income countries. Continuous monitoring of pathogens and their antibiotic resistance pattern is crucial for managing neonatal sepsis. This study aimed to determine neonatal sepsis due to bacteria, antibiotic resistance patterns, associated risk factors and patient outcomes at St. Paul's Hospital Millennium Medical College. METHOD: An institutional-based cross-sectional study was conducted on 400 neonates suspected of sepsis at St. Paul's Hospital Millennium Medical College from March 2020 to July 2020. A questionnaire was used to collect socio-demographic information, clinical parameters and potential risk factors from study participants. About 2ml of blood was drawn aseptically and inoculated into Tryptone Soya Broth at the patient's bedside. Bacterial identification was performed by using standard microbiological techniques. The disk diffusion method was used to determine the antibiotic susceptibility patterns of each isolated bacteria. Data entry and analysis were done using Statistical Package for Social Sciences (SPSS) version 20 software. Bivariate and multivariable logistic regressions were used to assess associated risk factors of neonatal sepsis. A p-value less than 0.05 was considered statically significant with a 95% confidence interval. RESULTS: The overall prevalence of neonatal septicemia was 21% (84/400). Of these, 67 (79.8%) and 17 (20.2%) were gram-negative and gram-positive bacteria, respectively. Klebsiella spp, 37 (44%), E. coli 19 (21.6%) and Coagulase negative Staphylococci 13 (15.47%) were the leading cause of neonatal sepsis. Ciprofloxacin and amikacin were the most effective antibiotics for gram-negative and gram-positive bacteria. Multidrug resistance was observed in 84% of the bacterial isolates. Low birth weight and preterm were associated with neonatal septicemia (AOR = 49.90, 95% CI = 15.14-123.081, P = 0.002) and (AOR = 18.20, 95% CI = 6.835-27.541, P = 0.004) respectively. CONCLUSION: Klebsiella spp and E. coli were frequently isolated bacteria in our study. The proportion of multidrug-resistance was significantly high. Most isolated bacteria were resistant to ampicillin, ceftazidime, cefotaxime and gentamycin, which indicates the necessity of continuous evaluation of antibiotic resistance rate.

Noninfectious influencers of early-onset sepsis biomarkers.

Diagnostic tests for sepsis aim to either detect the infectious agent (such as microbiological cultures) or detect host markers that commonly change in response to an infection (such as C-reactive protein). The latter category of tests has advantages compared to culture-based methods, including a quick turnaround time and in some cases lower requirements for blood samples. They also provide information on the immune response of the host, a critical determinant of clinical outcome. However, they do not always differentiate nonspecific host inflammation from true infection and can inadvertently lead to antibiotic overuse. Multiple noninfectious conditions unique to neonates in the first days after birth can lead to inflammatory marker profiles that mimic those seen among infected infants. Our goal was to review noninfectious conditions and patient characteristics that alter host inflammatory markers commonly used for the diagnosis of early-onset sepsis. Recognizing these conditions can focus the use of biomarkers on patients most likely to benefit while avoiding scenarios that promote false positives. We highlight approaches that may improve biomarker performance and emphasize the need to use patient outcomes, in addition to conventional diagnostic performance analysis, to establish clinical utility.

Neonatal sepsis and Kawasaki disease.

The purpose of this study is to clarify the relationship between neonatal sepsis and future development of Kawasaki disease (KD). We analyzed data from the National Hospital Organization Neonatal Intensive Care Unit (NHO-NICU) registry study in Japan. Participants in this study were children with a history of hospitalization in the NICU at the participating institutions from 2010 to 2014. A questionnaire was administered at age 3 years to obtain information about the patient's history of KD. There were 8275 infants who were eligible for this study. At 3 years of age, parents of 2161 children responded to the follow-up survey (follow-up rate, 26.1%). Multivariate logistic regression analysis adjusted for preterm birth, sex, use of antibiotics in the NICU, parity, and maternal smoking showed that children with neonatal sepsis were more likely to have a history of KD at 3 years of age (adjusted odds ratio [aOR]: 11.67, 95% confidence interval [CI]: 2.84-47.96). CONCLUSIONS: Among infants admitted to the NICU, neonatal sepsis might be associated with development of KD later in life. Further large studies are needed to elucidate the relationship between neonatal infections and KD development. WHAT IS KNOWN: • Preterm birth is known to be a risk factor for Kawasaki disease. •It is not yet known which factors related to preterm birth increase the risk of developing Kawasaki disease. WHAT IS NEW: •Neonatal sepsis is associated with an increased risk of subsequent development of Kawasaki disease. •Antibiotic use in the neonatal intensive care unit may also be an independent risk factor for subsequent development of Kawasaki disease.

Association between latency period and perinatal outcomes after preterm premature rupture of membranes at 32-37 weeks of gestation: a perinatal registry-based cohort study.

OBJECTIVES: To investigate association between latency after preterm premature rupture of membranes (PPROM) and perinatal outcomes at moderately and late preterm gestation. METHODS: National perinatal registry-based cohort study using data for the period 2013-2018. Singleton pregnancies with non-malformed fetuses in cephalic presentation complicated by PPROM at 32+0-36+6 weeks were included. Associations between latency period and perinatal mortality, neonatal respiratory distress syndrome (RDS), early onset neonatal infection (EONI), and cesarean section were assessed using multiple logistic regression, adjusting for potential confounders (labor induction, maternal body-mass-index, maternal age, antenatal corticosteroids, and small-for-gestational-age). p<0.05 was considered statistically significant. RESULTS: Of 3,017 pregnancies included, 365 (12.1%) had PPROM at 32+0-33+6 weeks and 2,652 (87.9%) at 34+0-36+6 weeks. Among all cases, 2,540 (84%) had latency <24 h (group A), 305 (10%) 24-47 h (group B), and 172 (6%) ≥48 h (group C). Longer latency was associated with higher incidence of EONI (adjusted odds ratio [aOR] 1.350; 95% confidence interval [CI] 0.900-2.026 for group B and aOR 2.500; 95% CI 1.599-3.911 for group C) and higher rate of caesarean section (aOR 2.465; 95% CI 1.763-3.447 for group B and aOR 1.854; 95% CI 1.172-2.932 for group C). Longer latency was not associated with rates of RDS (aOR 1.160; 95% CI 0.670-2.007 for group B and aOR 0.917; 95% CI 0.428-1.966 for group C). CONCLUSIONS: In moderately to late PPROM, increased latency is associated with higher risk of EONI and cesarean section with no reduction in RDS.

[A 10-year retrospective study of pathogens and antimicrobial resistance in neonatal sepsis]. / æ–°ç”Ÿå„¿è´¥è¡€ç—‡ç— åŽŸèŒåŠè€è¯æ€§10年回顾性分析.

OBJECTIVES: To investigate the changes in the pathogen spectrum and antimicrobial resistance over time in neonatal sepsis. METHODS: The medical data were collected from the neonates who were diagnosed with sepsis in the Second Xiangya Hospital of Central South University from January 2010 to December 2019. The incidence rate of sepsis, the pathogen spectrum, and the characteristics of antimicrobial resistance were analyzed. RESULTS: The incidence rate of neonatal sepsis was 4.02% (447/11 111). The top four pathogens detected were coagulase-negative staphylococci (CoNS), Klebsiella pneumoniae, Escherichia coli, and Candida. The incidence rate of sepsis and the pathogen spectrum showed no significant changes over time. Klebsiella pneumoniae was the most frequent pathogen in preterm infants, very low birth weight infants, and small-for-gestational-age infants, accounting for 33.9%, 29.5%, and 42.5%, respectively. CoNS, Klebsiella pneumoniae, and Escherichia coli had a high resistance rate to penicillins and third-generation cephalosporins. CONCLUSIONS: The incidence of neonatal sepsis is high, and the main pathogen is CoNS. The pathogens of neonatal sepsis have a high resistance rate to penicillins and third-generation cephalosporins. It is recommended to enhance the prevention and control of neonatal infection, strengthen the surveillance of pathogens, and further standardize the rational use of antibiotics.

Maternal Obesity and Risk of Early-onset Neonatal Bacterial Sepsis: Nationwide Cohort and Sibling-controlled Studies.

BACKGROUND: Maternal overweight and obesity are related to risks of pregnancy and delivery complications that, in turn, are associated with newborn infections. We examined the associations between early pregnancy body mass index (BMI; kg/m2) and risk of early-onset neonatal bacterial sepsis (EOS). METHODS: We conducted a nationwide population-based retrospective cohort study of 1 971 346 live singleton infants born in Sweden between 1997 and 2016. Outcome was a culture-confirmed EOS diagnosis. We estimated hazard ratios (HR) of EOS according to BMI using proportional hazard models, and identified potential mediators. Among term infants, we conducted sibling-controlled analyses. RESULTS: EOS risk per 1000 live births was 1.48; 0.76 in term and 15.52 in preterm infants. Compared with infants of normal-weight mothers (BMI, 18.5-24.9), the adjusted HR (95% confidence interval [CI]) of EOS for BMI categories <18.5, 25.0-29.9, 30.0-34.9, 35.0-39.9, and ≥40.0 were, respectively, 1.07 (.83-1.40), 1.19 (1.08-1.32), 1.70 (1.49-1.94), 2.11 (1.73-2.58), and 2.50 (1.86-3.38). Maternal overweight and obesity increased the risk of EOS by group B Streptococcus, Staphylococcus aureus, and Escherichia coli. Half of the association was mediated through preeclampsia, cesarean section delivery, and preterm delivery. A dose-response association was consistently apparent in term infants only. In sibling-controlled analyses, every kilogram per meter squared interpregnancy BMI change was associated with a mean 8.3% increase in EOS risk (95% CI, 1.7%-15.3%; P = .01). CONCLUSIONS: Risk of EOS increases with maternal overweight and obesity severity, particularly in term infants.

Comparison of maternal and neonatal outcomes between acute fatty liver of pregnancy and hemolysis, elevated liver enzymes and low platelets syndrome: a retrospective cohort study.

BACKGROUND: Acute fatty liver of pregnancy (AFLP) and hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome are two uncommon disorders that mimic each other clinically, but are distinct pathophysiologically. This study aimed to compare maternal and neonatal outcomes between AFLP and HELLP syndrome. METHODS: This retrospective cohort study was performed at a tertiary referral center in Taiwan between June 2004 and April 2020. We used the Swansea Criteria to diagnose AFLP, and the Tennessee Classification System to diagnose HELLP syndrome. Maternal characteristics, laboratory data, complications, and neonatal outcomes were compared. We analyzed the categorical variables with Chi-square test or Fisher's exact test and continuous variables with Student's t test or Mann-Whitney U test. Subsequent logistic regression analyses adjusting by potential confounding factors with significant difference were analyzed. RESULTS: During the study period, 21 women had AFLP and 80 women had HELLP syndrome. There was a higher rate of preeclampsia (95.0 % versus 23.8 %) in the HELLP syndrome group compared to the AFLP group. However, the AFLP group had more other maternal complications including jaundice (85.7 % versus 13.8 %), acute kidney injury (61.9 % versus 15.0 %), disseminated intravascular coagulopathy (66.7 % versus 8.8 %), and sepsis (47.6 % versus 10.0 %) compared to the HELLP syndrome group. Nevertheless, higher rates of small for gestational age neonates (57.1 % versus 33.3 %), neonatal respiratory distress syndrome (39.2 % versus 8.3 %) and neonatal sepsis (34.2 % versus 12.5 %) were noted in the HELLP syndrome group. CONCLUSIONS: AFLP is associated with a higher rate of multiple organ dysfunction in mothers, whereas HELLP syndrome is associated with a higher rate of neonatal morbidity.

Clinical chorioamnionitis at term X: microbiology, clinical signs, placental pathology, and neonatal bacteremia - implications for clinical care.

OBJECTIVES: Clinical chorioamnionitis at term is considered the most common infection-related diagnosis in labor and delivery units worldwide. The syndrome affects 5-12% of all term pregnancies and is a leading cause of maternal morbidity and mortality as well as neonatal death and sepsis. The objectives of this study were to determine the (1) amniotic fluid microbiology using cultivation and molecular microbiologic techniques; (2) diagnostic accuracy of the clinical criteria used to identify patients with intra-amniotic infection; (3) relationship between acute inflammatory lesions of the placenta (maternal and fetal inflammatory responses) and amniotic fluid microbiology and inflammatory markers; and (4) frequency of neonatal bacteremia. METHODS: This retrospective cross-sectional study included 43 women with the diagnosis of clinical chorioamnionitis at term. The presence of microorganisms in the amniotic cavity was determined through the analysis of amniotic fluid samples by cultivation for aerobes, anaerobes, and genital mycoplasmas. A broad-range polymerase chain reaction coupled with electrospray ionization mass spectrometry was also used to detect bacteria, select viruses, and fungi. Intra-amniotic inflammation was defined as an elevated amniotic fluid interleukin-6 (IL-6) concentration ≥2.6 ng/mL. RESULTS: (1) Intra-amniotic infection (defined as the combination of microorganisms detected in amniotic fluid and an elevated IL-6 concentration) was present in 63% (27/43) of cases; (2) the most common microorganisms found in the amniotic fluid samples were Ureaplasma species, followed by Gardnerella vaginalis; (3) sterile intra-amniotic inflammation (elevated IL-6 in amniotic fluid but without detectable microorganisms) was present in 5% (2/43) of cases; (4) 26% of patients with the diagnosis of clinical chorioamnionitis had no evidence of intra-amniotic infection or intra-amniotic inflammation; (5) intra-amniotic infection was more common when the membranes were ruptured than when they were intact (78% [21/27] vs. 38% [6/16]; p=0.01); (6) the traditional criteria for the diagnosis of clinical chorioamnionitis had poor diagnostic performance in identifying proven intra-amniotic infection (overall accuracy, 40-58%); (7) neonatal bacteremia was diagnosed in 4.9% (2/41) of cases; and (8) a fetal inflammatory response defined as the presence of severe acute funisitis was observed in 33% (9/27) of cases. CONCLUSIONS: Clinical chorioamnionitis at term, a syndrome that can result from intra-amniotic infection, was diagnosed in approximately 63% of cases and sterile intra-amniotic inflammation in 5% of cases. However, a substantial number of patients had no evidence of intra-amniotic infection or intra-amniotic inflammation. Evidence of the fetal inflammatory response syndrome was frequently present, but microorganisms were detected in only 4.9% of cases based on cultures of aerobic and anaerobic bacteria in neonatal blood.

miRNA-23b as a biomarker of culture-positive neonatal sepsis.

BACKGROUND: Neonatal sepsis remains an important cause of morbidity and mortality. The ability to quickly and accurately diagnose neonatal sepsis based on clinical assessments and laboratory blood tests remains difficult, where haemoculture is the gold standard for detecting bacterial sepsis in blood culture. It is also very difficult to study because neonatal samples are lacking. METHODS: Forty-eight newborns suspected of sepsis admitted to the Neonatology Department of the Mother-Child Specialized Hospital of Tlemcen. From each newborn, a minimum of 1-2 ml of blood was drawn by standard sterile procedures for blood culture. The miRNA-23b level in haemoculture was evaluated by RT-qPCR. RESULTS: miR-23b levels increased in premature and full-term newborns in early onset sepsis (p < 0.001 and p < 0.005 respectively), but lowered in late onset sepsis in full-term neonates (p < 0.05) compared to the respective negative controls. miR-23b levels also increased in late sepsis in the negative versus early sepsis negative controls (p < 0.05). miR-23b levels significantly lowered in the newborns who died from both sepsis types (p < 0.0001 and p < 0.05 respectively). In early sepsis, miR-23b and death strongly and negatively correlated (correlation coefficient = - 0.96, p = 0.0019). In late sepsis, miRNA-23b and number of survivors (correlation coefficient = 0.70, p = 0.506) positively correlated. CONCLUSIONS: Lowering miR-23b levels is an important factor that favours sepsis development, which would confirm their vital protective role, and strongly suggest that they act as a good marker in molecular diagnosis and patient monitoring.

Targeting the eCIRP/TREM-1 interaction with a small molecule inhibitor improves cardiac dysfunction in neonatal sepsis.

BACKGROUND: Neonatal sepsis and the associated myocardial dysfunction remain a leading cause of infant mortality. Extracellular cold-inducible RNA-binding protein (eCIRP) acts as a ligand of triggering receptor expressed on myeloid cells-1 (TREM-1). M3 is a small CIRP-derived peptide that inhibits the eCIRP/TREM-1 interaction. We hypothesize that the eCIRP/TREM-1 interaction in cardiomyocytes contributes to sepsis-induced cardiac dysfunction in neonatal sepsis, while M3 is cardioprotective. METHODS: Serum was collected from neonates in the Neonatal Intensive Care Unit (NICU). 5-7-day old C57BL/6 mouse pups were used in this study. Primary murine neonatal cardiomyocytes were stimulated with recombinant murine (rm) CIRP with M3. TREM-1 mRNA and supernatant cytokine levels were assayed. Mitochondrial oxidative stress, ROS, and membrane potential were assayed. Neonatal mice were injected with rmCIRP and speckle-tracking echocardiography was conducted to measure cardiac strain. Sepsis was induced by i.p. cecal slurry. Mouse pups were treated with M3 or vehicle. After 16 h, echocardiography was performed followed by euthanasia for tissue analysis. A 7-day survival study was conducted. RESULTS: Serum eCIRP levels were elevated in septic human neonates. rmCIRP stimulation of cardiomyocytes increased TREM-1 gene expression. Stimulation of cardiomyocytes with rmCIRP upregulated TNF-α and IL-6 in the supernatants, while this upregulation was inhibited by M3. Stimulation of cardiomyocytes with rmCIRP resulted in a reduction in mitochondrial membrane potential (MMP) while M3 treatment returned MMP to near baseline. rmCIRP caused mitochondrial calcium overload; this was inhibited by M3. rmCIRP injection impaired longitudinal and radial cardiac strain. Sepsis resulted in cardiac dysfunction with a reduction in cardiac output and left ventricular end diastolic diameter. Both were improved by M3 treatment. Treatment with M3 attenuated serum, cardiac, and pulmonary levels of pro-inflammatory cytokines compared to vehicle-treated septic neonates. M3 dramatically increased sepsis survival. CONCLUSIONS: Inhibition of eCIRP/TREM-1 interaction with M3 is cardioprotective, decreases inflammation, and improves survival in neonatal sepsis. Trial registration Retrospectively registered.

Neonatal sepsis and its association with birth weight and gestational age among admitted neonates in Ethiopia: systematic review and meta-analysis.

BACKGROUND: Neonatal sepsis is an invasive infection, usually bacterial, and often occurring during the neonatal period (0-28 days). Neonatal sepsis causes a high burden of morbidity and mortality in developing countries like Ethiopia. There are fragmented, inconsistency, and no review has been conducted to report the magnitude and associated factors of neonatal sepsis in Ethiopia. Thus, this study aimed to assess the pooled prevalence of neonatal sepsis and its association with birth weight and gestational age among admitted neonates in Ethiopia. METHODS: Electronic media searches like PubMed, CINHAL, EMBASE, Google Scholar, Web of Science, Cochrane library databases and African health science library were used. All original peer-reviewed papers which reported the prevalence of neonatal sepsis in Ethiopia were included in this study. Two reviewers independently extracted the data using a standardized data extraction format for eligibility and appraised their quality. Data were analyzed using Stata version 14 software. The pooled prevalence of neonatal sepsis was estimated with the random-effect model. Heterogeneity between studies was assessed by I 2 statistics test. Subgroup and meta-regression analyses were done to assess the source of variation between the studies. Egger's test followed by trim and fill analysis were used to determine publication bias. A sensitivity analysis was carried out. RESULT: A total of 952 research papers reviewed, of which, eight studies were finally included in this systematic review and meta-analysis. The random effect pooled prevalence of neonatal sepsis in Ethiopia was 49.98% (CI: 36.06, 63.90). In subgroup analysis, the pooled estimated neonatal sepsis among cross-sectional studies was 53.15% while the cohort was 40.56%. Newborns with a birth weight of less than 2.5 kg were 1.42 times more likely to develop neonatal sepsis infection compared to normal babies. The odds ratios of preterm babies were 3.36 to develop neonatal sepsis compared to term infants. CONCLUSION: The pooled prevalence of neonatal sepsis in Ethiopia was high. Thus, health care providers should adhere to aseptic precautions while performing procedures, especially in preterm and low birth weight infants were recommended.

Developing a Core Outcome Set for Cesarean Delivery Maternal Infectious Morbidity Outcomes.

OBJECTIVE: This study aimed to develop a core outcome set of primary outcomes for studies involving cesarean deliveries with infectious morbidity outcomes. STUDY DESIGN: Authors reported primary outcomes from 11 Cochrane systematic reviews (SRs), 12 other SRs, and 327 randomized controlled trials (RCTs). These outcomes were condensed into 20 primary outcome groups. Next, a modified Delphi technique was used to gain consensus on key outcomes. Authors from included SRs were sent a questionnaire consisting of a free response and multiple-choice questions. These data were used to propose a set of core outcomes. RESULTS: The most frequent outcomes in RCTs were composite "infectious outcomes" (24%) with the second most common being endometritis (12%). The most common reported SR outcomes were wound infection (21%) and endometritis (16%). For the Delphi survey free response portion, wound infection (88%) and endometritis (79%) were the most commonly endorsed outcomes. Chosen list outcomes were maternal mortality (83%), wound infection (83%), wound complications (86%), and postpartum endometritis (80%). The proposed final core outcome set for cesarean trials was endometritis (primary outcome), maternal mortality, wound infection, wound complications, febrile morbidity, and neonatal morbidity. CONCLUSION: Utilizing defined core outcomes in all studies of cesarean section can harmonize trial reports and allow data synthesis for meta-analyses.

A Retrospective Review of Neonatal Sepsis among GBS-Colonized Women Undergoing Planned Cesarean Section after Labor Onset or Rupture of Membranes.

Background: Sepsis is a leading cause of mortality and morbidity in neonates, with group B streptococcus (GBS) remaining the most frequent pathogen isolated from term infants. Surveillance data showed that the majority of cases of early-onset GBS disease were neonates born to women who either received no or suboptimal intrapartum antibiotic prophylaxis with a notable portion of those women having a missed opportunity to receive ≥4 hours of chemoprophylaxis. Women planning delivery by cesarean section who present in labor or rupture of membranes prior to their scheduled surgery are unlikely to receive optimal GBS chemoprophylaxis and thus their neonates are at risk of having sepsis. Materials and Methods. A retrospective cohort study of women-infant dyads was extracted from the Consortium on Safe Labor dataset. Women who had an unlabored cesarean section at ≥37 + 0 week gestation were selected and divided into four groups based on GBS status and timing of cesarean section with respect to onset of labor or rupture of membranes. The rate of neonatal sepsis and the patterns of intrapartum antibiotic chemoprophylaxis were determined. Results: The sepsis rate (4.5%) among neonates of GBS-colonized women having their unlabored cesarean section after onset of labor or rupture of membranes was significantly higher than that in any other group in this study. In this group, 9.4% of women received chemoprophylaxis for ≥4 hours, while 31% had a missed opportunity to receive ≥4 hours of chemoprophylaxis. Conclusion: This study suggests that neonates of GBS-colonized women having a planned cesarean section after onset of labor or rupture of membranes are at increased risk of having a sepsis diagnosis. This finding suggest the need for additional studies to assess the risk of sepsis among neonates of women in this group.

Leukocyte Counts and Other Hematological Values in Twin-Twin Transfusion Syndrome and Twin Anemia-Polycythemia Sequence.

OBJECTIVE: The aim of this study was to evaluate the differences in leukocyte counts at birth between donors and recipients with twin-twin transfusion syndrome (TTTS) or twin anemia-polycythemia sequence (TAPS). METHODS: We performed a retrospective cohort study in monochorionic twin pairs with TTTS or TAPS. TTTS and TAPS cases treated with fetoscopic laser surgery were excluded. Primary outcome was the difference in leukocyte levels at birth between donor and recipient twins and the presence of leukopenia (defined as leukocyte count <4 × 109/L). Secondary outcomes included early-onset sepsis, necrotizing enterocolitis, use of antibiotics during admission, and neonatal mortality. RESULTS: We included 99 twins pairs, of which 61 twin pairs were affected by TAPS and 38 twin pairs by TTTS. The mean leukocyte count at birth in donors and recipients was 7.5 × 109/L versus 7.4 × 109/L (p = 0.936), respectively. Leukopenia was significantly more common in donor twins compared to recipient twins (7.1% [7/99] vs. 0% [0/99], p = 0.016). Of the 7 donors with leukopenia, 6 were affected by TAPS and 1 by TTTS. Overall, donors were more often affected by early-onset sepsis than recipients, 23.7% (23/97) versus 13% (13.7/95) (p = 0.049), respectively. CONCLUSIONS: Leukocyte counts at birth in twins with TTTS or TAPS are similar between donors and recipients, but TAPS donors are at an increased risk of leukopenia. Overall, TTTS and TAPS donors seem to be at an increased risk of early-onset neonatal sepsis compared to recipient twins.

Prevalence, risk factors, and outcome of hospitalization of neonatal hyperglycemia at a Nigerian health facility.

BACKGROUND: Neonatal hyperglycemia (NNH) like hypoglycemia is a dangerous metabolic disorder often associated with adverse consequences, if undetected and untreated. This study was set out to determine the prevalence, risk factors, and outcomes of babies with the point of admission hyperglycaemia at the Wesley Guild Hospital (WGH), Ilesa. METHODS: The study was descriptive and cross-sectional, involving 300 consecutively recruited neonates admitted into the special care baby unit (SCBU) of the hospital. All subjects had blood glucose done at the point of admission using Accu-Chek Active® glucometer (Roche Diagnostics GmbH, Germany). Hyperglycemia was defined as blood glucose ≥7.0 mmol/L. Factors associated with NNH were determined using univariate and multivariate analyses. RESULTS: Of the 300 subjects (Male: Female 1.5:1), there were 74 (24.7%) preterms, 35 (11.7%) small-for-gestational age and 85 (28.3%) low-birth-weight babies. Eighteen (6.0%) babies had hyperglycemia. Parental low socioeconomic class, maternal lack of antenatal care (ANC), vaginal delivery, grand multiparity, outborn status, respiratory distress, probable sepsis, and neonatal anemia at presentation were associated with NNH (P < 0.05). Respiratory distress (OR = 3.800, 95% CI = 1.122-12.873, P = 0.032), and probable sepsis (OR = 4.090, 95% CI = 1.206-13.872, P = 0.024) were independent predictors of hyperglycemia. Hyperglycemia was significantly associated with mortality. (38.9% vs. 11.0%; P = 0.001). CONCLUSION: Neonatal hyperglycemia was detected in 6.0% of neonatal admission at the WGH, Ilesa and it was associated with increased mortality. Hyperglycemia should be suspected and promptly managed at the point of admission of ill newborns particularly those with respiratory distress and signs of sepsis.

Acute Funisitis Correlates With the Risk of Early-Onset Sepsis in Term Newborns Assessed Using the Kaiser Sepsis Calculator.

BACKGROUND: The risk of neonatal early-onset sepsis (EOS) is traditionally assessed on maternal signs of clinical chorioamnionitis. Recently, an online EOS risk calculator was developed by Kaiser Permanente using maternal and neonatal clinical parameters. We were interested in whether an increased Kaiser sepsis risk score correlates with histologic acute chorioamnionitis or acute funisitis. DESIGN: Included in this retrospective review are 119 chorioamnionitis-exposed term neonates from January 1, 2015 and December 31, 2016. Clinical charts from mother-baby pairs were reviewed. An EOS risk score was obtained using the online Kaiser Sepsis Calculator. The presence and severity of acute chorioamnionitis and acute funisitis were recorded. A SPSS software was used for statistical analysis (IBM, New Jersey, USA). RESULTS: The Kaiser Sepsis Calculator could identify 97 of 119 (81.5%) neonates without increased risk for sepsis. Histologic acute chorioamnionitis was present in 100 of 119 cases (84%), in which 44 cases (44%) show severe acute chorioamnionitis. Acute funisitis was recognized in 87 of 119 (73.1%) cases, all of which had concurrent acute chorioamnionitis. Severe funisitis was seen in 38 of the 87 cases (43.7%). The Kaiser Sepsis risk score correlates with the presence and severity of acute funisitis (P = .037 and P = .044, respectively) but not with the presence or the severity of acute chorioamnionitis (P = .105 and P = .672, respectively). CONCLUSION: Our study provides histological evidence to support that the Kaiser Sepsis Calculator may help to effectively reduce unwarranted blood culture, antibiotics exposure, and neonatal intensive care unit admission in term neonates.

Clinical Characteristic and Pathogen Spectrum of Neonatal Sepsis in Guangzhou City from June 2011 to June 2017.

BACKGROUND Preterm and low birth weight (birth weight <2500 g) neonates are vulnerable to sepsis, and the causative pathogens vary in different regions and times. The objective of this study was to identify common organisms leading to neonatal sepsis and identify the characteristic of patients infected with different bacteria, which may help in the selection of antibiotics for empirical treatment. MATERIAL AND METHODS We retrospectively collected the clinical and microbiological data of neonates with culture-proven sepsis in our clinical setting from June 2011 to June 2017. The demography, composition, and distribution of the pathogens and the clinical characteristic of the cases infected with different bacteria were analyzed. RESULTS Of a total of 1048 bacteria that were isolated from patient samples, detailed clinical and microbiological data of 297 cases were available. Escherichia coli, Klebsiella pneumoniae, and coagulase-negative Staphylococcus (co-NS) were the top 3 isolated pathogens. Streptococcus agalactiae predominantly led to early-onset sepsis, while K. pneumoniae and Staphylococcus aureus mainly led to late-onset sepsis. K. pneumoniae was mainly acquired in the hospital. Leukopenia was more commonly seen than leukocytosis in our study, and patients infected with K. pneumoniae and Candida spp encountered more thrombocytopenia. CONCLUSIONS The results of our study revealed the composition of the pathogens of neonatal sepsis in our region and the clinical characteristic of sepsis caused by different bacteria; these data may help in the selection of antibiotics for empirical treatment of neonates with high risk of sepsis.

Investigation of association between maternal 25-OH vitamin D serum levels and neonatal early onset sepsis in newborns by evaluating key factors.

BACKGROUND: The goal of this study was to evaluate the relationship between maternal 25-OH Vitamin D serum levels and neonatal early-onset sepsis in newborns by the effective factors. METHODS: A case-control study was done and 64 neonates hospitalized in Akbar Abadi Hospital (Tehran- Iran; 2016) and their mothers were enrolled. The case group consisted of 32 NICU term hospitalized neonates due to neonatal early-onset sepsis. Thirty-two term newborns that referred to hospital for rule out hyperbilirubinemia during the first 72 h of life were also considered as the control. RESULTS: Sixty- four mothers with mean age 28.76 ± 6.60 years and mean gestational age 39.64 ± 1.62 weeks entered the study. There was a significant correlation between sepsis and older age of mothers and low Apgar score (P-value = 0.02, 0.01 respectively). The maternal vitamin D serum level was reversely correlated with neonatal sepsis occurrence (P-value = 0.03). There was a significant correlation between maternal vitamin D supplement intake during pregnancy and lower risk for neonatal sepsis (P-value = 0.003). CONCLUSION: The level of maternal serum Vitamin D was inversely correlated with neonatal sepsis occurrence and intake of vitamin D supplement during pregnancy could decrease the risk of early neonatal sepsis.
