OBJECTIVE: There is widespread overuse of antibiotics in neonatal intensive care units (NICUs). The objective of this study was to safely reduce antibiotic use in participating NICUs by targeting early-onset sepsis (EOS) management. STUDY DESIGN: Twenty-eight NICUs participated in this statewide multicenter antibiotic stewardship quality improvement collaborative. The primary aim was to reduce the total monthly mean antibiotic utilization rate (AUR) by 25% in participant NICUs. RESULT: Aggregate AUR was reduced by 15.3% (p

BACKGROUND: Neonatal Escherichia coli (E coli) meningitis results in significant morbidity and mortality. We present a case of a premature infant with extensive central nervous system (CNS) injury from recurrent E coli infection and the non-traditional methods necessary to identify and clear the infection. CASE PRESENTATION: The infant was transferred to our institutions pediatric intensive care unit (PICU) after recurrence of E coli CNS infection requiring neurosurgical intervention. He had been treated for early onset sepsis (EOS) with ampicillin and gentamicin for 10 days followed by rapid development of ampicillin-resistant E coli septic shock and meningitis after discontinuation of antibiotics. Sterility of the CNS was not confirmed at the end of 21 days of cefepime therapy and was subsequently followed by recurrent ampicillin-resistant E coli septic shock and CNS infection. Despite 6 weeks of appropriate therapy with sterility of CSF by traditional methods, he suffered from intractable seizures with worsening hydrocephalus. Transferred to our institution, he underwent endoscopic 3rd ventriculostomy with cyst fenestration revealing purulent fluid and significant pleocytosis. An additional 3 weeks of systemic and intraventricular antibiotics with cefepime and tobramycin were given but a significant CNS neutrophil-predominant pleocytosis persisted (average of ∼ 21,000 cells/mm3). Repeated gram stains, cultures, polymerase chain reaction (PCR) testing, and metagenomic next generation sequencing (NGS) testing of CSF were negative for pathogens but acridine orange stain (AO) revealed numerous intact rod-shaped bacteria. After the addition of ciprofloxacin, sterility and resolution of CSF pleocytosis was finally achieved. CONCLUSION: Neonatal E coli meningitis is a well-known entity but unlike other bacterial infections, it has not proven amenable to shorter, more narrow-spectrum antibiotic courses or limiting invasive procedures such as lumbar punctures. Further, microbiologic techniques to determine CSF sterility suffer from poorly understood limitations leading to premature discontinuation of antibiotics risking further neurologic damage in vulnerable hosts.

Objective We aimed to determine the composite maternal hemorrhagic outcome (CMHO) among individuals with and without hypertensive disorders of pregnancy (HDP), stratified by disease severity. Additionally, we investigated the composite neonatal adverse outcome (CNAO) among individuals with HDP who had postpartum hemorrhage (PPH) versus did not have PPH. Study Design Our retrospective cohort study included all singletons who delivered at a Level IV center over two consecutive years. The primary outcome was the rate of CMHO, defined as blood loss ≥1,000 mL, use of uterotonics, mechanical tamponade, surgical techniques for atony, transfusion, venous thromboembolism, intensive care unit admission, hysterectomy, or maternal death. A subgroup analysis was performed to investigate the primary outcome stratified by (1) chronic hypertension, (2) gestational hypertension and preeclampsia without severe features, and (3) preeclampsia with severe features. A multivariable regression analysis was performed to investigate the association of HDP with and without PPH on a CNAO which included APGAR <7 at 5 minutes, bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, seizures, neonatal sepsis, meconium aspiration syndrome, ventilation >6 hours, hypoxic–ischemic encephalopathy, or neonatal death. Results Of 8,357 singletons, 2,827 (34%) had HDP. Preterm delivery <37 weeks, induction of labor, prolonged oxytocin use, and magnesium sulfate usage were more common in those with versus without HDP (p < 0.001). CMHO was higher among individuals with HDP than those without HDP (26 vs. 19%; adjusted relative risk [aRR] = 1.11, 95% CI: 1.01–1.22). In the subgroup analysis, only individuals with preeclampsia with severe features were associated with higher CMHO (n = 802; aRR = 1.52, 95% CI: 1.32–1.75). There was a higher likelihood of CNAO in individuals with both HDP and PPH compared to those with HDP without PPH (aRR = 1.49, 95% CI: 1.06–2.09). Conclusion CMHO was higher among those with HDP. After stratification, only those with preeclampsia with severe features had an increased risk of CMHO. Among individuals with HDP, those who also had a PPH had worse neonatal outcomes than those without hemorrhage. Key Points Individuals with HDP had an 11% higher likelihood of CMHO. After stratification, increased CMHO was limited to those with preeclampsia with severe features. There was a higher likelihood of CNAO in those with both HDP and PPH compared to HDP without PPH.

Background: While a systematic review exists detailing neonatal sepsis outcomes from clinical trials, there remains an absence of a qualitative systematic review capturing the perspectives of key stakeholders. Objectives: Our aim is to identify outcomes from qualitative research on any intervention to prevent or improve the outcomes of neonatal sepsis that are important to parents, other family members, healthcare providers, policymakers, and researchers as a part of the development of a core outcome set (COS) for neonatal sepsis. Search Strategy: A literature search was carried out using MEDLINE, EMBASE, CINAHL, and PsycInfo databases. Selection Criteria: Publications describing qualitative data relating to neonatal sepsis outcomes were included. Data Collection and Analysis: Drawing on the concepts of thematic synthesis, texts related to outcomes were coded and grouped. These outcomes were then mapped to the domain headings of an existing model. Main Results: Out of 6777 records screened, six studies were included. Overall, 19 outcomes were extracted from the included studies. The most frequently reported outcomes were those in the domains related to parents, healthcare workers and individual organ systemas such as gastrointestinal system. The remaining outcomes were classified under the headings of general outcomes, miscellaneous outcomes, survival, and infection. Conclusions: The outcomes identified in this review are different from those reported in neonatal sepsis clinical trials, thus highlighting the importance of incorporating qualitative studies into COS development to encapsulate all relevant stakeholders' perspectives.

This article provides insights into the left heart dynamics in neonatal cold septic shock through a case series of infants with septic shock and cardiovascular dysfunction. The study emphasizes the need for further research on the prognostic value of echocardiography in septic children and the lack of large-scale neonatal data on cardiovascular dysfunction in sepsis. The infants in the case series experienced various symptoms and echocardiograms revealed low biventricular output and valve regurgitation. The article discusses the importance of early and serial assessments using echocardiography and highlights the potential impact of cardiac dysfunction on outcomes. However, more prospective studies are needed in this area. [Extracted from the article]

The need of the hour is to incorporate a rapid assay that could efficiently detect neonatal sepsis. We evaluated the diagnostic utility of 16SrRNA broad-range polymerase chain reaction (PCR) in neonatal sepsis. The demographic and clinical details of 100 neonates clinically suspected to have sepsis were collected adopting pretested clinical proforma, followed by baseline laboratory investigations, including blood culture, complete blood counts, and C-reactive protein (CRP). Around, 0.2–0.3 ml of the EDTA blood was subjected to enrichment followed by DNA isolation using the modified spin column method. Based on the blood culture report, neonates were further divided into the suspected sepsis group (n = 50) and the confirmed sepsis group (n = 50). We performed 16SrRNA broad-range PCR to identify the presence of bacteria, and the results were analyzed statistically using SPSS software. Neonates in both groups were found to have clinical parameters comparable to each other except for birth weight, length, and head circumference, which was found to be lower in the culture-positive group than in culture-negative group (p < 0.05). The diagnosis of neonatal sepsis by 16SrRNA broad-range PCR compared to blood culture revealed 100% sensitivity, 64% specificity, and 73.5% positive and 100% negative predictive value. The 18 cases detected positive by PCR had clinical and other diagnostic findings consistent with sepsis. The 16SrRNA broad-range PCR effectively ruled out sepsis in 32 neonates within 8 h of sample collection compared to blood culture, which took 24 h. The method may not replace blood culture but can be used to complement it. [ABSTRACT FROM AUTHOR]

Background: Babies born via caesarean section in low-income settings face a higher risk of early-onset neonatal sepsis (EONS), which has greater mortality than late-onset sepsis. However, maternal factors contributing to EONS among caesarean-delivered babies in these settings, including Uganda, are not well documented. We determined maternal factors associated with EONS among term babies delivered by caesarian section at Mbarara Regional Referral Hospital (MRRH), southwestern Uganda. Methods: We conducted an unmatched case-control study at MRRH from December 2019 to March 2020. Cases were caesarean section-delivered term babies with EONS (within 72 h). Controls were caesarean section-delivered term babies without EONS. We enrolled mother-baby pairs for both groups, obtaining maternal data via structured questionnaires The diagnosis of EONS was made using the WHO Young Infant Integrated Management of Childhood Illnesses algorithm. Cases were consecutively recruited while controls were recruited by simple random sampling in a ratio of 1:2. We excluded newborns whose mothers were too ill to consent. We used multivariable logistic regression analysis to identify maternal factors associated with EONS. Results: We enrolled 52 cases and 104 controls. The mean age for the mothers was 27 (± 5.5) years. Neonates born to referred mothers had higher odds of EONS than those born to non-referred mothers (AOR = 6.2, 95% CI: 1.8–21). Additionally, decision-to-delivery time > 1 h for emergency caesarean section (AOR = 16, 95% CI: 4.2–65), antepartum hemorrhage (AOR = 8.0, 95% CI: 1.6–40), primiparity (AOR = 4.8, 95% CI: 1.1–21), and > 3 vaginal examinations after membrane rupture (AOR = 4.3, 95% CI: 1.5–12) were associated with EONS. Conclusions: Prime gravidity, antepartum hemorrhage, multiple vaginal examinations after membrane rupture, long decision-to-delivery time, and referral status were associated with EONS among term babies delivered by caesarean section at MRRH. To reduce EONS risk, clinicians should limit post-membrane rupture vaginal exams or consider prophylactic antibiotics if multiple exams are needed. Screening babies born to primiparous women, those referred, those with antepartum hemorrhage, multiple vaginal exams after membranes rupture, and long decision-to-delivery times, could aid prompt recognition of EONS and timely interventions. Implementing standard procedures to reduce caesarean decision-to-delivery time could reduce risk for EONS in this setting. [ABSTRACT FROM AUTHOR]

Background: Neonatal sepsis represents a significant cause of morbidity and mortality among infants in healthcare settings. This study explored nurses' experiences in preventing and managing neonatal sepsis in the Tamale metropolis. Methods: An exploratory, descriptive qualitative cross-sectional study design was used, and data was collected using semi-structured interviews. The sample size was determined at the point of data saturation of fifteen participants. Thematic analysis was employed to identify codes, subthemes, and themes within the interview transcripts. Results: Three major challenges nurses face in preventing and managing neonatal sepsis, including (1) the absence of a protocol for handling newborns upon admission, (2) an excessive workload that made it difficult for staff to follow infection prevention protocols, and (3) inadequate, obsolete and/or lack of equipment that caused devices to be overused. The nurses also identified critical psychological and emotional difficulties they encounter as a result of working within such a stressful environment. Other activities nurses conducted were handwashing before and after every procedure, infection prevention, and separating the babies in the incubator. In managing babies with neonatal sepsis, nurses provided daily treatment, hygiene care, and supported activities of living. The nurses also assert that the availability of resources, appropriate staff, and critical skills are important for preventing and managing neonatal sepsis. Conclusion: The lack of basic working consumables like gloves, syringes, and needles, inadequate staff, and lack of defined protocol of care were identified as critical challenges that hamper the care provided in neonatal care units. Hospital authorities must focus attention on addressing the critical challenges faced by neonatal care units. Also, measures should be instituted to address the emotional and psychological concerns associated with nursing care. Future research must consider the level of influence of each of the challenges enumerated on nurses' overall health. Plain language summary: In many developing countries deaths of under-five children are associated with neonatal sepsis - an acute infection that occurs in those less than 28 days old. Nurses are critical in the care and services rendered to these babies and their families in the neonatal care units. This study assessed the experiences of nurses in providing care to neonates. The data was collected using an interview guide among nurses working in neonatal care units in the Tamale metropolis. Analysis was done using the thematic data analysis method. Some challenges were identified by nurses to be associated with the care of babies with neonatal sepsis. These challenges included a lack of definitive protocols of care; higher workload; inadequate, obsolete, and lack of basic equipment and consumables. Nurses employed handwashing techniques to prevent infection among babies with neonatal sepsis. Services providers must focus attention on providing the requisite support to nurses caring for babies with neonatal sepsis to improve the care experiences. [ABSTRACT FROM AUTHOR]

Streptococcus agalactiae, or Group B Streptococcus (GBS), is a leading cause of neonatal sepsis. Materno-fetal transmission of the microorganisms present in the lower genital tract/perineum is considered to be the most frequent mode for acquisition of infection. It has also been proposed that, in a subset of cases, GBS causes acute chorioamnionitis, intraamniotic infection, and fetal/neonatal sepsis. However, the evidence to support this ascending pathway is derived from microbiologic studies that rely on cultivation methods, which do not have the resolution to determine if the microorganisms causing neonatal sepsis are the same as those found in the amniotic fluid and the vaginal ecosystem.We used whole genome sequencing of the microorganisms isolated from the vagina, amniotic fluid, chorioamniotic membranes, and neonatal blood (four isolates) in a case of early neonatal sepsis. Using hybrid genome assembly, we characterized the genomic features including virulence factors and antimicrobial resistance in four isolates from the same mother, placenta, and newborn.Whole genome sequencing revealed that the microorganisms in the four clinical isolates corresponded to S. agalactiae sequence type 1, clonal complexes 1, and serotype Ib. Comparative genomic analysis illustrated similar DNA sequences of the four genomes.This study presents the first evidence of the genomic similarity of microorganisms in the vaginal ecosystem, the space between the chorioamniotic membranes of the placenta, amniotic fluid, and neonatal blood.

Objective This study aimed to examine whether the addition of latency antibiotics in late preterm rupture of membranes (ROM) decreases neonatal infection and increases latency. Study Design This retrospective two-center study was conducted at Holy Family Hospital (HFH) in Nazareth and Emek Medical Center (EMC) in Afula, on data collected between January 2017 and April 2023. HFH is the smaller institution. EMC and HFH implement similar policies regarding ROM at 34 0/7 to 36 6/7 weeks' gestation; the only difference is that a 10-day course of latency antibiotics is implemented at EMC. All women with ROM between 34 0/7 and 36 6/7 weeks' gestation who were admitted to one of the centers during the study period, and had a live fetus without major malformations, were included. The primary outcome was neonatal sepsis rate. Secondary outcomes included a composite of neonatal sepsis, mechanical ventilation ≥24 hours, and perinatal death. Additionally, gestational age at delivery and delivery mode were examined. Results Overall, 721 neonates were delivered during the study period: 534 at EMC (where latency antibiotics were administered) and 187 at HFH. The gestational age at ROM was similar (35.8 and 35.9 weeks, respectively, p = 0.14). Neonatal sepsis occurred in six (1.1%) neonates at EMC and one (0.5%) neonate at HFH (adjusted p = 0.71; OR: 1.69; 95% Confidence Interval [CI]: 0.11–27.14). The composite secondary outcome occurred in nine (1.7%) and three (1.6%) neonates at EMC and HFH, respectively (adjusted p = 0.71; OR: 0.73; 95% CI: 0.14–3.83). The gestational age at delivery was 36.1 and 36.2 weeks at EMC and HFH, respectively (mean difference: 5 h; adjusted p = 0.02). The cesarean delivery rate was 24.7% and 19.3% at EMC and HFH, respectively (adjusted p = 0.96). Conclusion Latency antibiotics administered to women admitted with ROM between 34 0/7 and 36 6/7 weeks' gestation did not decrease the rate of neonatal sepsis. Key Points Latency antibiotics in late preterm ROM does not decrease neonatal sepsis. Latency antibiotics in late preterm ROM does not prolong gestational age at delivery. Latency antibiotics in late preterm ROM does not affect the mode of delivery. [ABSTRACT FROM AUTHOR]

Background: Copeptin is an immediate biomarker of individual stress response; many life-threatening diseases are causing a high elevation of its concentration in plasma, such as myocardial infarction and cardiovascular shock. Moreover, copeptin is a promising marker in sepsis. We aimed to evaluate copeptin as a diagnostic and prognostic marker in neonatal sepsis for the early initiation of appropriate therapy and the prediction of mortality. A prospective case-control study involved 237 neonates (165 cases had neonatal sepsis, and 72 served as controls). Cases were admitted to the neonatal intensive care unit (NICU) and followed up for symptoms and signs of sepsis confirmed by laboratory data: complete blood count (CBC), c-reactive protein (CRP), and cultures. Serum copeptin level by the enzyme-linked immunosorbent assay (ELISA) was measured for all included neonates. We observed that the copeptin level was significantly higher in cases than control (3.51 ± 1.4, 1.61 ± 0.51 pmol/liter, respectively). The cut-off value of copeptin at which we can discriminate between cases and controls was above 2.065 pmol/liter. Among cases, copeptin was higher in early-onset sepsis (EOS) than late-onset sepsis (LOS) neonates, and there was a significant correlation between its level and all the following: age at admission, birth weight, gestational age, history of perinatal asphyxia, maternal chorioamnionitis, and premature rupture of membrane (PROM). Also, copeptin was strongly associated with CRP level and the poor prognosis of patients. Copeptin can predict the death of cases at a cut-off value above 2.995 pmol/liter. Conclusion: Serum copeptin level can be used as a diagnostic and prognostic marker in neonatal sepsis. [ABSTRACT FROM AUTHOR]

Background: Significant numbers of neonatal deaths occurring each year are caused by infections that can be directly associated with improper and unhygienic umbilical cord care practices. The objectives of this study were to describe the umbilical cord care practices among mothers whose babies were admitted for suspected sepsis at the Federal Teaching Hospital and Turai Umaru Yar’adua Maternal and Children Hospital Katsina, Nigeria, assess the relationship between umbilical cord care practices and neonatal sepsis, and the influence of home delivery on this relationship. Methodology: This was a hospital-based descriptive observational study of 60 selected neonates with clinical features of sepsis admitted into the special care baby unit (SCBU) of the two hospitals between July and December 2022. The study involved the collection and microbiological analysis of blood samples using the BacT/Alert microbial detection system, and the administration of a structured questionnaire on the mother of each enrollee to collect relevant information about cord care practices. Data were analyzed using SPSS version 22.0. The Chisquare (x 2 ) test and Odds ratio (with 95% confidence interval) were used to determine the association of risk factors with culture-confirmed sepsis, and a p value less than 0.05 was considered statistically significant. Results: Of the 60 neonates blood samples, 31 (51.7%) were culture-positive for neonatal sepsis while 29 (48.3%) were culture-negative. There was no statistically significant association between risk factors such as application of traditional materials for cord care and place of delivery, and culture-confirmed neonatal sepsis (p>0.05). However, neonates whose mothers use traditional materials for cord care were more likely to develop sepsis than those who do not (OR=2.027, 95% CI=0.716-5.736). Concerning place of delivery, which is an important determinant of umbilical cord hygiene, babies delivered at home were almost 3 times more likely to have culture-confirmed sepsis than those delivered in the hospital (OR=2.975, 95% CI=1.040-8.510). A total of 26 out of the 60 (45.3%) mothers of the neonates agreed to have used unhygienic and traditional materials for cord care, with charcoal (39.0%), local herbs (27.0%), cow dung/urine concoction (19.0%), and others (15.0%), such as lubricants, ash, and balm, being the most commonly used materials for cord care. Conclusion: Neonatal infection is common among newborns in Federal Teaching Hospital and Turai Umaru Yar’adua Maternal and Children Hospital (TUYMCH), Katsina, northwest Nigeria, with a prevalence of culture confirmed neonatal sepsis of 51.7%. Although there was no statistically significant association between unhygienic cord practices and neonatal sepsis in this study, babies whose mothers use traditional materials for cord care were more likely to develop sepsis. There is a high rate of use of harmful and unhygienic traditional materials for cord care in our environment. This habit can be discouraged through health education using the mass media and health talks in health facilities. The use of chlorhexidine, the recommended antiseptic for cord care by the World Health Organization and the Nigeria Federal Ministry of Health, should be encouraged. [ABSTRACT FROM AUTHOR]

Objective: To determine the frequency, associated risk factors, and outcome of meningitis in neonates presenting with sepsis at Aga khan Tertiary Care Hospital, Karachi. Methods: A descriptive cross-sectional study was conducted at pediatrics department of Aga Khan Tertiary University Hospital, Karachi, Pakistan from July 31, 2020, till January 30, 2021. Neonates of either gender admitted with neonatal sepsis were enrolled using non-probability consecutive sampling technique. Meningitis was diagnosed as per the findings of cerebrospinal fluid (CSF) along with the outcome in terms of death and early neurological complications such as subdural effusions and hydrocephalus. Results: Of 209 neonates with sepsis, meningitis was observed in 59 (28.2%) neonates. A significantly lower mean weight (p-value 0.024) while significantly higher mean duration of stay (p-value <0.001) was observed in patient with meningitis. Moreover, a significantly higher proportion of meningitis was observed in neonates who had fever (p-value 0.048), vomiting (p-value 0.009), abdominal distension (p-value <0.001), and blood culture positivity (p-value <0.001). Blood culture positive Methicillin-sensitive Staphylococcus aureus (MSSA) was considerably higher among neonates with meningitis. Of 59 neonates with meningitis, mortality was observed in 2 (3.4%) neonates. Positive CSF culture was observed in 6 (2.9%) while hydrocephalus was observed in 7 (11.9%) and effusion in 6 (10.2%) neonates. Conclusion: Neonatal meningitis is common in neonates presenting with sepsis, but mortality rate is low. Positive cultures, particularly with MSSA, further underscore the bacterial etiology in neonatal meningitis. [ABSTRACT FROM AUTHOR]

Sepsis remains a significant contributor to neonatal mortality worldwide. However, the nonspecific nature of sepsis symptoms in neonates often leads to the necessity of empirical treatment, placing a burden of ineffective treatment on patients. Furthermore, the global challenge of antimicrobial resistance is exacerbating the situation. Artificial intelligence (AI) is transforming medical practice and in hospital settings. AI shows great potential for assessing sepsis risk and devising optimal treatment strategies. Background/Objectives: This review aims to investigate the application of AI in the detection and management of neonatal sepsis. Methods: A systematic literature review (SLR) evaluating AI methods in modeling and classifying sepsis between 1 January 2014, and 1 January 2024, was conducted. PubMed, Scopus, Cochrane, and Web of Science were systematically searched for English-language studies focusing on neonatal sepsis. Results: The analyzed studies predominantly utilized retrospective electronic medical record (EMR) data to develop, validate, and test AI models to predict sepsis occurrence and relevant parameters. Key predictors included low gestational age, low birth weight, high results of C-reactive protein and white blood cell counts, and tachycardia and respiratory failure. Machine learning models such as logistic regression, random forest, K-nearest neighbor (KNN), support vector machine (SVM), and XGBoost demonstrated effectiveness in this context. Conclusions: The summarized results of this review highlight the great promise of AI as a clinical decision support system for diagnostics, risk assessment, and personalized therapy selection in managing neonatal sepsis.

Lactobacillus rhamnosus GG (LGG) is a widely used and extensively researched probiotic. Probiotic effects are considered to be strain specific. We aimed to comprehensively assess the strain-specific effects of LGG in preterm infants. A systematic review of RCTs and non-RCTs to evaluate the effect of LGG in preterm infants. We followed the Cochrane methodology, and preferred reporting items for systematic reviews (PRISMA) statement for conducting and reporting this review. We searched the Cochrane central register of controlled trials, PubMed, EMBASE and CINAHL databases till December 2023. The review was registered in PROSPERO 2022 CRD42022324933. Meta-analysis of data from RCTs that used LGG as the sole probiotic showed significantly lower risk of NEC ≥Stage II [5 RCTs, n = 851, RR:0.50 (95% CI: 0.26, 0.93), P = 0.03] in the LGG group. There was no significant difference in the risk of LOS [7 RCTs, n = 1037, RR:1.08 (95% CI 0.84, 1.39), P = 0.55], mortality [3 RCTs, n = 207, RR: 0.99 (95% CI: 0.42, 2.33), P = 0.99], time to reach full feeds [2 RCTs, n = 19, SMD = 0.11 days (95% CI: −0.22, 0.45), P = 0.51] and duration of hospital stay [3 RCTs, n = 293, SMD: −0.14 days (95% CI: −0.37 to 0.09), P = 0.23]. Meta-analysis of data from non-RCTs showed no significant effect of LGG on NEC, LOS, and mortality. RCTs showed beneficial effects of LGG when used as the sole probiotic in reducing the risk of NEC, whereas observational studies did not. Strain-specific systematic review of LGG provides important data for guiding research and clinical practice. [ABSTRACT FROM AUTHOR]

BACKGROUND AND OBJECTIVES: The Kaiser Permanente Neonatal Early-Onset Sepsis (EOS) Calculator has been an effective tool for risk stratification to safely reduce newborn antibiotic exposure. The calculator was derived from data on infants born between 1993 and 2007. Since that time, US obstetric practice has adopted universal antepartum screening for group B Streptococcus and intrapartum antibiotic prophylaxis guidance has changed. Our objective was to update the EOS calculator using a contemporary birth cohort and determine the effect of these changes on EOS case ascertainment and antibiotic recommendations. METHODS: The study included infants born at $35 weeks' gestation at 14 hospitals between January 2010 and December 2020 (n = 412 595 infants, EOS cases = 113). Model coefficients were re-estimated and the point estimates of the likelihood ratios for clinical status used to calculate the posterior probability of EOS. We compared the number of EOS cases correctly identified by each model (sensitivity) and the proportion of infants for whom empirical antibiotics are recommended. RESULTS: The original model had a sensitivity of 0.76 (95% confidence interval 0.63-0.85), while the updated model had a sensitivity of 0.80 (95% confidence interval 0.68-0.89), P 5 .15. The recommended empirical antibiotic use was 3.5% with the original model and 3.7% with the updated model, P < .0001. For each additional case identified by the updated model, an additional 158 infants would be treated with antibiotics. CONCLUSIONS: Both the original and updated EOS calculators are effective tools for quantifying EOS risk among infants born at $35 weeks' gestation. [ABSTRACT FROM AUTHOR]

Early-onset sepsis is one of the leading causes of neonatal morbidity and mortality worldwide and timely diagnosis is, therefore, of paramount importance. As there is a lack of literature regarding early alteration of the cerebral blood flow (CBF) in neonatal sepsis, our study aimed to appraise changes in the CBF velocities and Doppler indices in neonates with early-onset neonatal sepsis (EONS) and to assess its diagnostic accuracy.A total of 99 neonates were recruited in the study; 56 neonates with EONS, and the age-matched 43 neonates without any manifestations of sepsis. A Transcranial Doppler examination and cerebral hemodynamics were assessed in neonates during the first seventy-two hours of life. Doppler indices and CBFV were measured in the anterior cerebral artery (ACA), and middle cerebral artery (MCA), of either side. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated.A significantly lower resistance in Resistivity (RI) and Pulsatility (PI) indices, a significant high end-diastolic velocity (EDV), and relatively higher peak systolic velocity (PSV) in both ACA and MCA have been documented within 72 hours of birth in neonates with EONS compared to the control group of neonates without sepsis.Our Study revealed that assessment of CBF at early hours of birth by Transcranial Doppler examination showed alteration in cerebral hemodynamics in neonates with EONS with an increase in the CBF and a decrease in the resistance. It can be adopted as a bedside, noninvasive tool with immediate diagnostic value. [ABSTRACT FROM AUTHOR]

Background: Myelomeningocele (MMC) is a congenital malformation affecting the central nervous system, categorized as a neural tube defect (NTDs). In untreated cases, the mortality rate within the first six months of life ranges from 35% to 70%. Globally, its incidence is estimated 0.8 to 1 per 1000 live births, and rates are higher in Asia and lower socioeconomic groups. This disease imposes a significant treatment cost and burden due to life-long disabilities. In less developed or developing countries, delays in diagnosis can lead to complications such as infection and rupture. Although rupture is a rare complication in MMC, there are limited studies that have reported it. This study aims to discuss the perioperative management and potential complications of ruptured MMC. Method: This study presents four cases of ruptured MMC that were referred from private hospitals and managed by Hasan Sadikin General Hospital in West Java, Indonesia. Each patiens underwent a clinical assessment and diagnostic evaluation upon arrival, followed by perioperative theraphy and management of any complications that emerged during treatment. Result: In three of the four cases, the children were over 24 h old when they were admitted to the hospital. Three cases were located in the lumbosacral region while one case was located in the thoracic region. Upon arrival, the clinical presentations we observed included microcephaly, small for gestational age (SGA) and congenital talipes equionavrus (CTEV). And we found several complications included wound dehisence, respiratiory failure, hydrocephalus, leg weakness, menigitis and sepsis after surgery. Conclusions: Perioperative management is highlighted as vital, necessitating a multidisciplinary approach and precise surgical techniques to mitigate severe complications. [ABSTRACT FROM AUTHOR]

Objective: We aimed to determine the demographic data, mortality, and morbidity of early- and late-neonatal sepsis cases, the etiologic agents in these cases, and the antibiotic susceptibility of these agents. Methods: This study was conducted retrospectively in a tertiary neonatal intensive care unit (NICU). The demographic, clinical, and laboratory data of newborns diagnosed with culture-proven sepsis within 24 months were evaluated. Results: Two hundred and eleven culture data points belonging to 197 infants were evaluated. Forty percent of the infants had a history of premature birth. The most common clinical findings were respiratory distress and feeding intolerance. Coagulase-negative staphylococci (CoNS) were detected most frequently as early- and late-sepsis agents. The most common Gram-negative bacteria detected as late-sepsis agents were Klebsiella spp. and Escherichia coli (E. coli). The overall mortality rate was 10%. Conclusions: Neonatal sepsis continues to have high mortality rates in tertiary NICUs. CoNS was the most common agent, highlighting the importance of developing and maintaining personnel training and handwashing practices. It will be important to consider the resistance rates of Klebsiella spp., the most common Gram-negative agent in late-onset sepsis (LOS) cases, to commonly used antibiotics in empirical treatments.

Klebsiella pneumoniae is well recognized as a serious cause of infection in healthcare-associated settings and immunocompromised individuals; however, accumulating evidence from resource-limited nations documents an alarming rise in community-acquired K. pneumoniae infections, manifesting as bacteremia and pneumonia as well as neonatal sepsis. The emergence of hypervirulent and antibiotic-resistant K. pneumoniae strains threatens treatment options for clinicians. Effective vaccination strategies could represent a viable alternative that would both preempt the need for antibiotics to treat K. pneumoniae infections and reduce the burden of K. pneumoniae disease globally. There are currently no approved K. pneumoniae vaccines. We review the evidence for K. pneumoniae lipopolysaccharide (LPS) as a vaccine and immunotherapeutic target and discuss the role of antibodies specific for the core or O-antigen determinants within LPS in protection against Klebsiella spp. disease. We expand on the known role of the Klebsiella spp. capsule and O-antigen modifications in antibody surface accessibility to LPS as well as the in vitro and in vivo effector functions reported for LPS-specific antibodies. We summarize key hypotheses stemming from these studies, review the role of humoral immunity against K. pneumoniae O-antigen for protection, and identify areas requiring further research.

Background: Sepsis is the 3rd leading cause of neonatal mortality in Ethiopia contributing to 16% of neonatal death. In a hospital study, neonatal sepsis was the leading diagnosis at admission and the second leading cause of neonatal death at the neonatal intensive care unit. Among other factors repeated vaginal examination during labor is known to contribute to sepsis in low-income settings. However, there is limited evidence in the Ethiopian setting. Objective: The objective of this study was to examine the association between early-onset neonatal sepsis and repeated vaginal examinations. Methods: The study was conducted at Gandhi Memorial Hospital, a public maternity and newborn care hospital. We followed 672 mother-newborn pairs by phone until 7 days of age to detect clinical sepsis. Data were analyzed using SPSS version 20 software. Adjusted odds ratio risk (AOR) with a corresponding 95% confidence interval (CI) was used to show the strength of associations and variables with p-value < 0.05 were considered to be statistically significant. Results: The incidence of early-onset neonatal sepsis was found to be 20.83% (95% CI 17.60, 24.00). Having a frequent vaginal examination (four or more times) during labor and delivery, prolonged rupture of membranes, induced labor and gestational age < 37 weeks were strongly associated with the development of early-onset neonatal sepsis, (AOR 2. 69;95 CI: 1.08, 6.70) AOR 5.12(95% CI 1.31, 20.00), AOR of 5.24 (95% CI 1.72, AOR4.34 (95% CI 1.20, 15.68), 16.00), respectively. Conclusion: Frequent digital vaginal examination prolonged rupture of membranes, induced labor and gestational age < 37 weeks significantly increases the risk of early onset neonatal sepsis. We also recommend further study using neonatal blood culture to better diagnose early onset neonatal sepsis objectively. [ABSTRACT FROM AUTHOR]

Neonatal sepsis, a bloodstream infection in the first 28 days of life, is a leading cause of morbidity and mortality among infants in both developing and developed countries. Additionally, sepsis is distinguished in neonates by unique pathophysiological and presentational factors relating to its development in immature neonatal immune systems. This review focuses on the current understanding of the mechanics and implications of neonatal sepsis, providing a comprehensive overview of the epidemiology, aetiology, pathophysiology, major risk factors, signs and symptoms and recent consensus on the diagnosis and management of both early-onset and late-onset neonatal sepsis. It also includes a discussion on novel biomarkers and upcoming treatment strategies for the condition as well as the potential of COVID-19 infection to progress to sepsis in infants.

Neonatal sepsis is a severe medical condition that contributes significantly to neonatal mortality. However, early diagnosis and treatment can help manage the condition effectively. Predictive analytics can assist neonatal sepsis diagnosis and treatment and offer a reassuring solution. This study presents a systematic literature review of various predictive analytics methods for neonatal sepsis diagnosis and treatment. It thoroughly reviews 16 studies between 2014 and 2024, including retrospective and prospective data and utilizing various predictive modeling techniques, such as Machine Learning (ML) and Deep Learning (DL). The review unveils that the Predictive analytics models can rapidly detect early and late-onset neonatal sepsis. This detection aids clinicians in decision-making and improves healthcare management for neonates, especially in low-resource settings. This study lays the groundwork for utilizing advanced analytics technologies to address challenges in this domain. It inspires further research in innovative and unexplored methods for neonatal sepsis diagnosis. [ABSTRACT FROM AUTHOR]

Background: Sepsis is a leading cause of neonatal mortality, despite the availability of effective treatment of possible serious bacterial illness (PSBI), including when referral to a hospital is not feasible. Gaps in access and delivery worsened during COVID-19. We conducted embedded implementation research in Ethiopia and Kenya aimed at mitigating the impact of COVID-19 and addressing various implementation challenges to improve PSBI management. Methods: The implementation research projects were implemented at the subnational level in Ethiopia and Kenya between November 2020-June 2022 (Ethiopia) and December 2020-August 2022 (Kenya). Guided by the implementation research frameworks, both projects conducted mixed formative quantitative and exploratory research from April to May 2021, followed by summative evaluations conducted between June and July 2022. Frameworks encompassed Consolidated Framework for Implementation Research (CFIR), Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM), as well as health systems framework that incorporates cascades of care and World Health Organization Health Systems Building Blocks. Results were synthesized across the projects through document review and sharing cross-project measures and strategies through a project community of practice. Results: Despite differences in settings across the projects, cross-cutting facilitators included community health worker program and support, and existence of guidelines for PSBI management at primary care levels. Barriers included community attitudes towards seeking care for sick newborns, COVID-19 risks and fear, and lack of health care worker competence. Country-specific contextual barriers included supply chain issues, civil conflict (Ethiopia), and labor strikes (Kenya). Strategies chosen to mitigate barriers and support implementation and sustainability in both settings included leveraging community health workers to address resistance to care-seeking, health workers' training, COVID-19 infection prevention measures, stakeholder engagement, and advocacy to integrate PSBI management into existing programs, policies, and training. Other strategies addressing emerging project-specific barriers, included improving follow-up through a community health desk and PSBI mobile app (Kenya) and supply chain strengthening (Ethiopia). Both projects improved PSBI management coverage, increased adoption and uptake, and informed national policy changes supporting potential for sustainability. Conclusions: Pragmatic embedded implementation research effectively supports the identification of barriers and mapping to strategies designed to increase effective coverage of PSBI management when referral is not feasible during the COVID-19 pandemic. Despite differences in context, cross-cutting strategies identified could inform broader scale-up in the region, including during future health system shocks. [ABSTRACT FROM AUTHOR]

Klebsiella pneumoniae is the leading cause of neonatal sepsis and is increasingly difficult to treat owing to antibiotic resistance. Vaccination represents a tractable approach to combat this resistant bacterium; however, there is currently not a licensed vaccine. Surface polysaccharides, including O-antigens of lipopolysaccharide, have long been attractive candidates for vaccine inclusion. Herein we describe the generation of a bioconjugate vaccine targeting 7 predominant O-antigen subtypes in K. pneumoniae. Each bioconjugate was immunogenic in isolation, with limited cross-reactivity among subtypes. Vaccine-induced antibodies demonstrated varying degrees of binding to a wide variety of K. pneumoniae strains. Furthermore, serum from vaccinated mice induced complement-mediated killing of many of these strains. Finally, increased capsule interfered with the ability of O-antigen antibodies to bind and mediate killing of some K. pneumoniae strains. Taken together, these data indicate that this novel heptavalent O-antigen bioconjugate vaccine formulation exhibits limited efficacy against some, but not all, K. pneumoniae isolates.

Background: Epidemiological profiles and the rundown crisis of antimicrobial resistance from bacterial isolates in neonatal sepsis compel regular surveillance to enhance data-driven decision-making. Accordingly, this study aimed to assess the phenotypic epidemiology and antimicrobial resistance profiles of bacteria isolated from clinically suspected neonatal sepsis in Ethiopia. Methods: A total of 342 neonates suspected of clinical sepsis were randomly included in a prospective observational study conducted at the neonatal intensive care unit (NICU) of Jimma medical center (JMC) from May 2022 to July 2023. Blood samples were collected from each neonate and subjected to a culture test for identification of bacterial isolates and their antibiotic resistance profiles following the standardized guidelines. The laboratory results, along with relevant clinical data, were recorded using WHONET and analyzed using STATA software. Results: Out of the 342 blood samples that were analyzed, 138 samples (40.4%, 95% CI: 35.1–45.6, P<0.01) exhibited proven bacterial infection. The infection rates were notably higher in males with 85/138 (61.6%, 95% CI: 53.4–69.8, P<0.01) and neonates aged 0–3 days with 81/138 (58.7%, 95% CI: 50.5–66.9, P<0.01). The majority of the infections were attributed to Gram-negative bacteria, accounting for 101/138(73.2%, 95% CI: 65.6–80.7) cases, with 69/101(68.3%, 95% CI: 63.8–72.8) cases involving ESBL-producing strains, while Gram-positive bacteria were responsible for 26.8% (95% CI: 19.3–34.4) of the infections. The predominant isolates included Klebsiella pneumoniae (37.7%, 95% CI: 29.6–45.8), Coagulase-negative Staphylococci (CoNs) (20.3%, 95% CI: 13.6–27.0), and Acinetobacter species (11.6%, 95% CI: 6.0–17.1). Of the total cases, 43/72 (59.7%, 95% CI: 48.4–71.1, P<0.01) resulted in mortality, with 28/72 (38.9%, 95% CI: 27.70–50.1, P<0.03) deaths linked to Extended-Spectrum Beta-Lactamase (ESBL)-producing strains. Klebsiella pneumoniae displayed high resistance rates to trimethoprim-sulfamethoxazole (100%), ceftriaxone (100%), cefotaxime (98.1%), ceftazidime (90.4%), and gentamicin (84.6%). Acinetobacter species showed resistance to ampicillin (100%), cefotaxime (100%), trimethoprim-sulfamethoxazole (75%), ceftazidime (68.8%), chloramphenicol (68.8%), and ceftriaxone (68.8%). Likewise, CoNs displayed resistance to ampicillin (100%), penicillin (100%), cefotaxime (86.0%), gentamicin (57.2%), and oxacillin (32.2%). Multidrug resistance was observed in 88.4% (95% CI: 81.8–93.0) of isolates, with ESBL-producers significantly contributing (49.3%, 95% CI: 45.1–53.5). Furthermore, 23.0% (95% CI: 15.8–31.6) exhibited a prevalent resistance pattern to seven distinct antibiotic classes. Conclusion: The prevalence and mortality rates of neonatal sepsis were significantly high at JMC, with a notable surge in antibiotic and multidrug resistance among bacterial strains isolated from infected neonates, specifically ESBL-producers. These resistant strains have a significant impact on infection rates and resistance profiles, highlighting the requisite for enhanced diagnostic and antimicrobial stewardship, stringent infection control, and further molecular characterization of isolates to enhance neonatal survival.
