Abstract
INTRODUCTION Neonatal sepsis is a key contributor to neonatal mortality worldwide, and low- and middle-income countries (LMIC) are disproportionately affected. With antimicrobial resistance challenging effective treatment of neonatal sepsis, it is increasingly urgent to improve infection prevention and control (IPC) in LMIC neonatal units (NNU) and reduce transmission of infections. One pathway to improvement which merits further exploration is the collaboration with families to build an IPC intervention.Families are constantly present on neonatal units, and much of the hands-on care for their newborns is given by them. For IPC to be effective, families must adhere to IPC standards within the NNU, but furthermore, any IPC intervention implemented must be feasible and acceptable for families as well as the hospital staff as this will increase uptake and effectiveness of the intervention. This scoping review aims to provide an overview of parental involvement in infection prevention and control in low- and middle-income setting neonatal units. METHODS AND ANALYSIS This protocol was developed in line with the Joanna Briggs Institute recommendations. Searches will be carried out on six databases (Medline, CINAHL, Global Health, EMBASE, Web of Science and Global Index Medicus), and reference searching will be carried out on included studies. The search will be carried out from 2000 to present (end date 28/02/2024), and included languages will be English, French, Spanish and Portuguese. Screening and data extraction will be performed independently by two reviewers, with a third reviewer to resolve conflicts. Results will be reported by narrative synthesis of each sub-question in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. ETHICS AND DISSEMINATION This study will be carried out using already published data exclusively and therefore does not require further ethical approval. Results will be disseminated through peer-reviewed publications and conference presentations and through engagement with peers and relevant stakeholders.

Abstract
BACKGROUND Neonatal sepsis is a significant cause of morbidity and mortality in low- income countries. Neonatal sepsis is classified as early-onset neonatal sepsis (EONS) and late-onset neonatal sepsis (LONS). Etiologies responsible for EONS are mostly acquired vertically from the mother during or before birth with the possibility of prevention. The burden and etiology of neonatal sepsis is not uniform across the globe with huge disparities based on the income level of the countries. This study aimed to determine neonatal sepsis trends, prevalence, and etiologies at Hawassa University Comprehensive Specialised Hospital (HUCSH). METHODS A hospital-based retrospective cross-sectional study was conducted among newborns aged 0 to 90 days who were admitted to the HUCSH from January 2019 to July 2023. Patient-related information and the culture results were obtained from HUCSH microbiology laboratory registration book. Data analysis was performed using SPSS version 25 software. RESULTS Out of 2364 newborns suspected of having sepsis, 56% (95% CI: 54-58%) had culture-confirmed sepsis. When excluding Coagulase Negative Staphylococcus (CONS), the prevalence of culture-confirmed neonatal sepsis was 36.9%. The highest numbers of culture-confirmed cases was observed in 2021. The predominant bacteria identified were Coagulase Negative Staphylococcus (CONS) (34.1%), Klebsiella pneumoniae (12.9%), and Enterococcus (10.6%). Among culture-confirmed neonatal sepsis, 59.9% and 40.1% of cases were EONS and LONS, respectively. Coagulase Negative Staphylococcus and Enterococcus were the major bacteria found in both EONS and LONS while. Klebsiella pneumoniae was the second most common bacteria among newborns with EONS following CONS. CONCLUSIONS The prevalence of culture-confirmed neonatal sepsis was relatively high in the study area. Early-onset neonatal sepsis was consistently more prevalent than LONS. The predominant etiologies of neonatal sepsis excluding CONS were K. pneumoniae, Enterococcus, Enterobacter agglomerans, Acinetobacter species, and Staphylococcus aureus. Among newborns with EONS, the predominant bacteria were K. pneumoniae, Enterococcus, Enterobacter agglomerans, and Acinetobacter species.

Abstract
BACKGROUND Early-onset sepsis (EOS) remains a significant cause of morbidity and mortality in neonates worldwide, particularly in low-income countries. Identification of causative bacterial pathogens and assessment of their antimicrobial susceptibility are essential for guiding appropriate therapy and improving outcomes. The aim of this study was to determine the incidence, bacteriological profile and antibiotic susceptibility patterns of culture-positive EOS among a cohort of neonates in the Occupied Palestinian Territories (oPt). METHODS This retrospective observational study was conducted on neonates with proven positive blood cultures or positive cerebrospinal fluid (CSF) admitted to eight neonatal intensive care units (NICU) in the West Bank, oPt between January 2017 and December 2019. Data on microbiology laboratory blood cultures were retrieved from NICU registers and medical records were reviewed to obtain data on mothers and neonates. RESULTS Among the 95,319 neonates admitted to the eight NICUs during the study period, we detected 292 neonates with culture-proven EOS, resulting in an incidence rate of 3 per 1000 live births. The most common gram-positive bacteria identified among neonates were α hemolytic streptococcus (11.6%), CoNS (11.3%), and GBS (8.6%). E. coli (15.1%) and Klebsiella spp. (15.1%) were the most common gram-negative bacteria, followed by Acinetobacter (7.9%). Findings revealed gram-positive organisms were resistant to ciprofloxacin (57.1%) and highly sensitive to vancomycin (97.9%), meropenem (89.2%), amikacin (82.6%) and Piperacillin-Tazobactam (82.4%). Gram-negative organisms showed the highest antibiotic resistance to ampicillin (87.2%), cetofaxime, and highest sensitivity to meropenem (82.0%), Piperacillin-Tazobactam (70.7%), and amikacin (66.4%). CONCLUSION Our findings underscore the importance of continuous surveillance of bacterial pathogens and their antimicrobial susceptibility patterns in the management of EOS among neonates in Palestinian hospitals. The findings generated will guide clinicians in selecting appropriate empirical therapies and facilitating early and targeted interventions. Future research should focus on strategies to enhance infection prevention and control measures in Palestinian neonatal care unites to mitigate the burden of EOS and antimicrobial resistance.

Abstract
Background The World Health Organization (WHO) has developed guidance for community health workers (CHWs) in identifying sick young infants based on clinical signs. We conducted a prospective, observational cohort study to characterise mortality risk of young infants based on their clinical signs. Methods We conducted a population-based, prospective observational cohort study at five sites in Bangladesh (Sylhet, November 01, 2011-December 31, 2013), India (Vellore and Odisha, September 01, 2013-February 28, 2015), and Pakistan (Karachi, January 01, 2012-December 31, 2013; Matiari, March 01, 2012-December 31, 2013) to identify newborn infants who were followed-up by CHWs through 10 scheduled home visits over the first 60 completed days after birth to identify signs of possible serious bacterial infection (PSBI). We determined the frequency of signs and conducted Cox regression to investigate the association of signs with mortality risk within 7 days of identification of the signs. Findings CHWs made 522,309 visits to assess 63,017 young infants and found ≥1 sign(s) of PSBI at 14,245 visits (2.7%), including 5.8% (5568 of 96,390) and 1.8% (6635 of 365,769) of visits of infants 0-<3 and 7-<60 days of age, respectively. Each of the seven signs of PSBI when found alone was associated with significantly (p < 0.0001) increased risk for mortality, which increased further if any other additional sign of PSBI was found concurrently. Over the young infant period (days 0-<60) CHW identification of no movement or movement only on stimulation was associated with the highest risk for mortality [adjusted hazard ratio (aHR) 73.0, 95% confidence interval (CI) 44.4-119.9] followed by poor feeding (aHR 31.9, 95% CI 24.1-42.3) and hypothermia (<35.5 °C) (aHR 31.4, 95% CI 23.5-41.9). Hypothermia had particularly high risk for mortality during days 7-<60 (HR 45.1, 95% CI 27.6-73.4). Interpretation WHO reconsideration of hypothermia as a sign of critical illness is warranted. Implementation research is urgently needed to reduce infant mortality by ensuring immediate referrals and interventions for children identified early by CHWs with no movement or movement only on stimulation, hypothermia, or poor feeding, especially in resource-poor settings.

Theoretical impact of a bedside decision-making tool on antibiotic use for suspected neonatal healthcare-associated infection: an observational study. BMC Pediatr 2025; 25:52.

Abstract
BACKGROUND AND OBJECTIVES Healthcare-associated infections (HAI) are a leading contributor to morbidity and mortality in hospitalised neonates. Diagnosing neonatal HAI is challenging owing to non-specific symptoms and lack of definitive diagnostic markers, contributing to high rates of inappropriate antibiotic use. This study evaluated the theoretical impact of implementing a bedside tool for decision-making on antibiotic length of therapy (LOT). METHODS This prospective observational physician-blinded study consecutively enrolled patients with suspected HAI events at a large South African neonatal unit from September 2022 to September 2023. The antibiotic decision-making tool included an infection prediction score (NeoHoP), and a point-of-care C-reactive protein test (CRP) performed at HAI diagnosis and 24 h later. The theoretical impact of the tool on antibiotic LOT was calculated. RESULTS We recruited 180 neonates with 214 episodes of suspected HAI, of which 22 (10.3%) were proven HAI, 56 (26.2%) were presumed HAI and 136 (63.6%) had HAI ruled out. The median observed antibiotic LOT was three days (9 days for proven HAI, 7 days for presumed HAI, and 3 days for no HAI). The antibiotic decision-making tool would theoretically reduce overall antibiotic LOT by 2 days (p < 0.001), particularly in neonates where HAI was subsequently excluded. CONCLUSION We developed an antibiotic decision-making tool to support the clinical evaluation of suspected neonatal HAI and demonstrated a significant potential impact on reducing antibiotic LOT. Given increasing antibiotic resistance rates globally, this tool should be further evaluated to minimise unnecessary antibiotic use in hospitalised neonates.

Abstract
Background/Objectives: Neonatal sepsis is a systemic inflammation in neonates caused by bacteria, viruses, or fungi that can progress into severe conditions. In developing countries, neonatal sepsis is a major cause of mortality and a major public health issue with a high prevalence. This study aims to evaluate the antibiotic prescription practice and resistance patterns of bacterial isolates from the neonatal intensive care unit (NICU) at the largest governmental hospital in Amman, Jordan. Methods: This was a retrospective cross-sectional study. The antibiotic prescription practice and resistance patterns of bacterial isolates from the NICU at Al Basheer Government Hospital in Amman, Jordan, were evaluated. The hospital's microbiology lab database and medical records were the sources of the retrospective data collection. Results: A total of 266 neonates treated with antibiotics were assessed. The findings showed that most neonates had late-onset sepsis (LOS) (65.4%). The penicillin group of antibiotics (ampicillin) was the most highly prescribed first empiric antibiotic for LOS and early-onset sepsis (EOS) (61.7%). Aminoglycosides (60.9%) were the most prescribed antibiotics as a second empiric treatment for EOS and LOS. The culture results showed that resistance to antibiotics was as follows: 15.4% of the culture samples were resistant to penicillin (Micrococcus and Viridans streptococci), 13.9% were resistant to cefotaxime (Klebsiella pneumoniae and Viridans streptococci), 13.2% were resistant to cefoxitin (Klebsiella pneumoniae and Staphylococcus epidermidis), and 12.4% were resistant to oxacillin (Klebsiella pneumoniae and Staphylococcus epidermidis). Conclusions: This retrospective study sheds light on the antibiotic prescription practice and resistance patterns of bacterial isolates from newborns with sepsis. The results highlight the high rates of antibiotic resistance. These findings underline the urgent need for improved antibiotic stewardship and infection control strategies to prevent resistance from spreading further.

Abstract
INTRODUCTION Neonatal sepsis is the third leading cause of neonatal mortality, which occurs due to bacterial infection and is a major public health problem, especially in developing countries. Efforts to reduce the rates of infection in this vulnerable population are one of the most important interventions in neonatal care. This study aimed to compare the levels of biomarkers such as presepsin, procalcitonin, interleukin 6 (IL-6), fetuin, and CRP in cord blood between preterm and term infants and evaluate their association with neonatal sepsis. MATERIAL AND METHODS A total of 176 infants were included in this study. Cord blood samples were collected from preterm (gestational age < 37 weeks) and term (gestational age ≥ 37 weeks) infants immediately after delivery. Umbilical cord blood was assessed for C-reactive protein (CRP), presepsin, procalcitonin, IL-6, and fetuin by using enzyme-linked immunosorbent assay (ELISA). The Pearson correlation coefficient test (r) was used to test for a positive or negative relationship between 2 (presepsin and fetuin) variables with CRP and procalcitonin. A receiver operating characteristic (ROC) analysis was executed to describe a cutoff value of the studied biomarkers. RESULTS When compared to term newborns, preterm infants have considerably higher values for CRP, presepsin, procalcitonin, and IL-6. Elevated levels of presepsin, procalcitonin, and IL-6 in cord blood were significantly associated with an increased risk of neonatal distress in both preterm and term infants (p < 0.05). Fetuin levels showed a trend towards association with neonatal distress but did not reach statistical significant. A Pearson correlation study between CRP and presepsin and fetuin shows that CRP is positively correlated with presepsin; however, procalcitonin shows positive correlation with fetuin. Further, these results were confirmed with ROC analysis. CONCLUSIONS In early diagnosis of neonatal sepsis, compared with procalcitonin, presepsin and IL-6 seems to provide better early diagnostic value with consequent rapid therapeutic decision making and possible positive impact on neonatal prognosis. Elevated levels of these biomarkers are associated with risk of neonatal distress, highlighting their potential utility as early markers for identifying at-risk infants.

[PMID: 39636929 PMCID: PMC11620348 DOI: 10.1371/journal.pone.0310259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 08/27/2024] [Indexed: 12/07/2024] Open
Abstract
Severe bacterial infections (SBIs) are a leading cause of neonatal deaths in low- and middle-income countries. World Health Organization's (WHO's) guideline for outpatient management of danger signs indicating possible serious bacterial infections (PSBI) when referral is not possible was adopted by three pilot district councils in Mbeya Region, in Tanzania (Busekelo, Kyela and Mbarali Districts) in 2018 (the PSBI project). This study documented changes in practice during the PSBI project, and lessons learned. A cross-sectional study was conducted using both qualitative and quantitative data collection methods between July 2021 and January 2022, post-implementation. The study participants comprised stakeholders, health workers, community health workers, and mothers/fathers/caregivers who had a young infant with PSBI. Study tools included record review, quantitative, in-depth, and key informant interviews. Quantitative data were analysed using STATA version 15 (STATACorp Inc., TX, USA), whereas qualitative data were analysed using a framework analysis approach. Our assessment showed that 2,228 young infants (0-59 days old) from the three districts were classified as having PSBI. The majority, 1,607 (72.1%) had fast breathing as the only danger sign, while 621 (27.9%) were classified as having severe illness. All 621 young infants with severe illness were counselled and offered referral to a higher-level health facility; however, only 174 of them (28%) accepted the referral. The remaining 447 severely ill infants, for whom referral was not possible, were treated at the primary health facilities with gentamicin injection and amoxicillin dispersible tablets (DT). When referral is not feasible, outpatient treatment for young infants with signs of PSBI is possible within existing health system in Tanzania, based on experience after this pilot project. However, successful scale-up of outpatient management for PSBI will require commitments from government and key stakeholders to strengthen healthcare systems.

Abstract
BACKGROUND Reports of healthcare-associated bloodstream infection (HA-BSI) epidemiology in African neonatal units are limited. METHODS We conducted a cross-sectional study (2017-2018) in nine neonatal units in the Western Cape Province, South Africa, including central, regional and district hospitals (416 beds) using laboratory and clinical records. Patient demographics, HA-BSI rates, pathogen spectrum, and hospital outcomes and empiric antibiotic coverage rates were determined. RESULTS Over two years, 23,748 neonates were admitted with unit occupancy rates ranging from 79 to 93%. 485 HA-BSI episodes occurred, with median onset at 11 (IQR 7-24) days of life. Most HA-BSI episodes (348; 72%) affected very low birth weight neonates (< 1500 g). The overall HA-BSI rate was 2.0/1000 patient days. The highest HA-BSI rate was observed at the central unit with onsite surgery (3.8/1000 patient days). Crude HA-BSI mortality was 31.8% (154/485) with two-thirds of deaths occurring within three days of BSI onset. Higher mortality was observed for Gram-negative/fungal BSI compared to Gram-positive BSI (RR 1.5; 95%CI 1.1-2.0; p = 0.01) and very preterm neonates (gestation < 32 weeks) versus ≥ 32 weeks (RR 1.5; 95%CI 1.1-2.1; p = 0.01). Mean estimated empiric antibiotic coverage rates varied by unit type: 66-79% for piperacillin-tazobactam plus amikacin, 60-76% for meropenem and 84-92% for meropenem plus vancomycin. CONCLUSION Most HA-BSI events affected preterm neonates at the central hospital with onsite surgery. One-third of patients with HA-BSI died, with highest mortality in preterm infants and Gram-negative/fungal BSI. Empiric antibiotic regimens provide moderate coverage of circulating pathogens but require annual review given increasing carbapenem resistance rates.

Abstract
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
BACKGROUND The emergence and rapid spread of gram-negative bacteria resistant to carbapenems among newborns is concerning on a global scale. Nonetheless, the pooled estimate of gram-negative bacteria resistant to carbapenem that cause neonatal sepsis in developing nations remains unknown. Thus, this study aimed to determine the combined prevalence of gram-negative bacteria resistant to carbapenem in African newborns who were suspected of having sepsis. METHODS All studies published from January 1, 2010, up to December 30, 2023, from PubMed, Science Direct, Scopus electronic databases, and the Google Scholar search engine were researched. Isolates tested for carbapenem from neonates with sepsis, English language papers conducted in Africa, and cross-sectional and cohort studies papers were included. Using PRISMA guidelines, we systematically reviewed and meta-analyzed studies that assessed the prevalence of carbapenem-resistant gram-negative bacteria. The "Joanna Briggs Institute" was used critically to evaluate the quality of the included studies. The data analysis was carried out using STATA™ version 17. Heterogeneity across the studies was evaluated using Q and I 2 tests. The subgroup analysis was done and, funnel plot and Egger's regression test were used to detect publication bias. A sensitivity analysis was conducted. RESULTS All 36 studies were included in the meta-analysis and systematic review. The pooled prevalence of carbapenem resistance in Africa was 30.34% (95% CI 22.03-38.64%). The pooled estimate of gram-negative bacteria resistant to imipenem, and meropenem was 35.57% (95% CI 0.67-70.54%) and 34.35% (95% CI 20.04% - 48.67%), respectively. A. baumannii and Pseudomonas spp. had pooled prevalence of 45.9% (95% CI 33.1-58.7%) and 43.0% (95% CI 23.0-62.4%), respectively. Similarly, Pseudomonas spp. and A. baumannii also exhibited strong meropenem resistance, with a pooled prevalence of 29.2% (95% CI 4.8-53.5%) and 36.7% (95% CI 20.1-53.3%), respectively. E. coli and K. pneumoniae were the two most common isolates. CONCLUSION There should be urgent antimicrobial stewardship practices, strengthened surveillance systems and effective treatment for neonates with sepsis. There was remarkable variation in resistance across the continent.

Abstract
This study aimed to analyze the determinants of neonatal mortality over the last decade (2013-2023), identifying key factors that have influenced neonatal outcomes both before and during the COVID-19 pandemic. Utilizing a systematic literature review approach guided by the PRISMA method, this study evaluates 91 papers collected from indexed databases such as Scopus, PubMed, and Web of Science. The review encompasses studies conducted globally, offering insights into the evolution of neonatal mortality research and the impact of the COVID-19 crisis on neonatal health. The analysis revealed a complex array of risk determinants, categorized into socioeconomic factors, clinical factors, and healthcare access and quality. Notable factors include rural versus urban healthcare disparities, prenatal and postnatal care quality, and the influence of healthcare infrastructure on neonatal outcomes. This study highlights the shifting focus of neonatal mortality research in response to global health challenges, including the pandemic. The findings underscore the need for multidisciplinary approaches to address neonatal mortality, emphasizing the importance of enhancing healthcare systems, improving maternal education, and ensuring equitable access to quality care. Future research should explore the long-term effects of the COVID-19 pandemic on neonatal health and investigate the efficacy of interventions in diverse healthcare settings.

Abstract
CONTEXT Accurate identification of possible sepsis in young infants is needed to effectively manage and reduce sepsis-related morbidity and mortality. OBJECTIVE Synthesize evidence on the diagnostic accuracy of clinical sign algorithms to identify young infants (aged 0-59 days) with suspected sepsis. DATA SOURCES MEDLINE, Embase, CINAHL, Global Index Medicus, and Cochrane CENTRAL Registry of Trials. STUDY SELECTION Studies reporting diagnostic accuracy measures of algorithms including infant clinical signs to identify young infants with suspected sepsis. DATA EXTRACTION We used Cochrane methods for study screening, data extraction, risk of bias assessment, and determining certainty of evidence using Grading of Recommendations Assessment Development and Evaluation. RESULTS We included 19 studies (12 Integrated Management of Childhood Illness [IMCI] and 7 non-IMCI studies). The current World Health Organization (WHO) 7-sign IMCI algorithm had a sensitivity of 79% (95% CI 77%-82%) and specificity of 77% (95% CI 76%-78%) for identifying sick infants aged 0-59 days requiring hospitalization/antibiotics (1 study, N = 8889). Any IMCI algorithm had a pooled sensitivity of 84% (95% CI 75%-90%) and specificity of 80% (95% CI 64%-90%) for identifying suspected sepsis (11 studies, N = 15523). When restricting the reference standard to laboratory-supported sepsis, any IMCI algorithm had a pooled sensitivity of 86% (95% CI 82%-90%) and lower specificity of 61% (95% CI 49%-72%) (6 studies, N = 14278). LIMITATIONS Heterogeneity of algorithms and reference standards limited the evidence. CONCLUSIONS IMCI algorithms had acceptable sensitivity for identifying young infants with suspected sepsis. Specificity was lower using a reference standard of laboratory-supported sepsis diagnosis.

[PMID: 38723903 DOI: 10.1016/j.jhin.2024.04.015] [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: 02/21/2024] [Revised: 04/17/2024] [Accepted: 04/19/2024] [Indexed: 06/20/2024]
Abstract
BACKGROUND Healthcare-associated infections (HAIs) remain a global health challenge, and have elevated rates in Sub-Saharan Africa. HAIs impact patients and their families by causing illness, prolonged hospital stay, potential disability, excess costs and, sometimes, death. The costs of HAIs are increasing due to spreading antimicrobial resistance. A major risk factor for HAIs is lack of water, sanitation and hygiene (WASH); environmental cleaning and healthcare waste management. In Sub-Saharan Africa, these services are lacking in at least 50% of healthcare facilities. AIM To estimate the costs associated with HAIs at national level in 14 countries in Sub-Saharan Africa. METHODS Economic methodologies were employed to estimate the medical costs, productivity losses and value of premature death from HAIs, drawing on national statistics and published studies to populate the economic model. RESULTS In 2022, the number of HAIs was estimated at 4.8 million, resulting in 500,000 deaths. Health-related economic losses amounted to US$13 billion per year, equivalent to 1.14% of combined gross domestic product and US$15.7 per capita. Healthcare costs were US$500 per HAI, and represented 5.6% of total health expenditure. The costs of providing basic WASH were US$0.91 per capita, which, if they reduced HAIs by 50%, would result in benefit-cost ratios of 1.6 (financial healthcare savings alone) and 8.6 (all economic benefits). CONCLUSION HAIs have a major health and economic burden on African societies, and a significant proportion can be prevented. It is critical that health policy makers and practitioners dedicate policy space, resources and training to address HAIs.

Antibacterial activity of Nocardia spp. and Streptomyces sp. on multidrug-resistant pathogens causing neonatal sepsis. Rev Inst Med Trop Sao Paulo 2024; 66:e42. [PMID: 39082481 PMCID: PMC11295289 DOI: 10.1590/s1678-9946202466042] [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: 03/04/2024] [Accepted: 05/20/2024] [Indexed: 08/04/2024] Open
Abstract
Neonatal sepsis leads to severe morbidity and occasionally death among neonates within the first week following birth, particularly in low- and middle-income countries. Empirical therapy includes antibiotics recommended by WHO. However, these have been ineffective against antimicrobial multidrug-resistant bacterial strains such as Klebsiella spp, Escherichia coli, and Staphylococcus aureus species. To counter this problem, new molecules and alternative sources of compounds with antibacterial activity are sought as options. Actinobacteria, particularly pathogenic strains, have revealed a biotechnological potential still underexplored. This study aimed to determine the presence of biosynthetic gene clusters and the antimicrobial activity of actinobacterial strains isolated from clinical cases against multidrug-resistant bacteria implicated in neonatal sepsis. In total, 15 strains isolated from clinical cases of actinomycetoma were used. PCR screening for the PKS-I, PKS-II, NRPS-I, and NRPS-II biosynthetic systems determined their secondary metabolite-producing potential. The strains were subsequently assayed for antimicrobial activity by the perpendicular cross streak method against Escherichia fergusonii Sec 23, Klebsiella pneumoniae subsp. pneumoniae H1064, Klebsiella variicola H776, Klebsiella oxytoca H793, and Klebsiella pneumoniae subsp. ozaenae H7595, previously classified as multidrug-resistant. Finally, the strains were identified by 16S rRNA gene sequence analysis. It was found that 100% of the actinobacteria had biosynthetic systems. The most frequent biosynthetic system was NRPS-I (100%), and the most frequent combination was NRPS-I and PKS-II (27%). All 15 strains showed antimicrobial activity. The strain with the highest antimicrobial activity was Streptomyces albus 94.1572, as it inhibited the growth of the five multidrug-resistant bacteria evaluated.

Abstract
Bacterial infection is one of the major causes of neonatal morbidity and mortality worldwide. Finding rapid and reliable methods for early recognition and diagnosis of bacterial infections and early individualization of antibacterial drug administration are essential to eradicate these infections and prevent serious complications. However, this is often difficult to perform due to non-specific clinical presentations, low accuracy of current diagnostic methods, and limited knowledge of neonatal pharmacokinetics. Although neonatal medicine has been relatively late to embrace the benefits of machine learning (ML), there have been some initial applications of ML for the early prediction of neonatal sepsis and individualization of antibiotics. This article provides a brief introduction to ML and discusses the current state of the art in diagnosing and treating neonatal bacterial infections, gaps, potential uses of ML, and future directions to address the limitations of current studies. Neonatal bacterial infections involve a combination of physiologic development, disease expression, and treatment response outcomes. To address this complex relationship, future models could consider appropriate ML algorithms to capture time series features while integrating influences from the host, microbes, and drugs to optimize antimicrobial drug use in neonates. All models require prospective clinical trials to validate their clinical utility before clinical use.

BMC Pregnancy Childbirth 2024; 24:383. [PMID: 38778246 PMCID: PMC11112941 DOI: 10.1186/s12884-024-06583-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Accepted: 05/14/2024] [Indexed: 05/25/2024] Open
Abstract
BACKGROUND Neonatal sepsis is one of the most common causes of disease and death among neonates globally. And it made a great contribution to neonatal admission to intensive care units. To mitigate the ongoing neonatal crisis and accomplish the goal of sustainable development through a decrease in neonatal mortality, information from various regions is needed. Despite the considerable burden of neonatal sepsis in our setting, no prior studies were conducted in the study area. So, this study aimed to assess the magnitude and associated factors of neonatal sepsis among neonates admitted to the neonatal intensive care unit at Hawassa University Comprehensive Specialized Hospital, Sidama Regional State, Ethiopia. METHODS A hospital-based cross-sectional study was carried out among 287 neonates from March 1, 2020, to April 25, 2020. An interviewer-administered structured questionnaire was used to collect the data. The data were cleaned, coded, and entered into Epi Data 3.1 software and exported to Statistical Package for Social Science (SPSS) software version 23.0 for analysis. Binary logistic regression analyses were performed to identify variables having a significant association with neonatal sepsis. A p-value of ≤ 0.05 was considered statistically significant during multivariable logistic regression. RESULTS The study found that the magnitude of neonatal sepsis was 56%. The mean age of neonates was 3.2(SD±2.2) days. Around two-fifths (39%) of neonates were in the gestational age of <37 completed weeks. A quarter of mothers(25.8%) were delivered through cesarean section. During labor, 251 (87.5%) mothers had ≤4 digital vaginal examinations. Moreover, the finding revealed that mothers who delivered by cesarean section [AOR = 2.13, 95% CI (1.090-4.163)]. neonates who had been resuscitated at birth [AOR = 4.5, 95% CI (2.083-9.707)], and neonates who had NG tube inserted [AOR = 4.29, 95% CI (2.302-8.004)] were found to be significantly associated with neonatal sepsis. CONCLUSIONS The current study shows that neonatal sepsis was prevalent among more than half of the neonates admitted to the NICU. Therefore, designing strategies to enhance the aseptic techniques of professionals in the provision of care and actively and collaboratively working with cluster health facilities is highly recommended.

Abstract
Neonatal sepsis is a leading cause of morbidity and mortality in neonates, particularly in low- and middle-income countries. The emergence of antimicrobial resistance is a rapidly growing global problem. A significant proportion of the pathogens that commonly cause neonatal sepsis are resistant to multiple antibiotics. Therefore, for the empirical treatment of neonatal sepsis, the repurposing of older antibiotics that are effective against multidrug-resistant pathogens is being investigated. This review aims to provide an overview of current research and experience using the repurposed antibiotics colistin and fosfomycin for the empirical treatment of neonatal sepsis. Based on current knowledge, colistin and fosfomycin may be potentially helpful for the empirical treatment of sepsis in neonates due to their efficacy against a wide range of pathogens and acceptable safety profile.

Abstract
Background Neonatal sepsis is a serious blood bacterial infection in neonates at the age of equal to or less than 28 days of life, and it's still the major significant cause of death and long-term morbidity in developing countries. Objective This study aimed to assess the prevalence and related factors with neonatal sepsis among newborns admitted to the neonatal intensive care unit at Hiwot Fana Comprehensive Specialized University Hospital, Harar, Ethiopia. Methods An institutional-based retrospective cross-sectional study design was conducted among 386 neonates admitted to Neonatal Intensive Care Unit from September 2017 to August 2019. A systematic random sampling method was used. Data were analyzed using SPSS V.26. Descriptive summary statistics were done. Bivariate regression and multivariate analysis were computed. Variables with P-value <.05 were declared as having a statistically significant association. Result The prevalence of neonatal sepsis was 53.1%. Among the total neonates who had sepsis, 67.8% had early neonatal sepsis. Among neonatal factors, preterm neonates (AOR: 8.1, 95%CI: 2.1, 31.2), birth asphyxia (AOR: 4.7, 95%CI: 1.6, 13.6); and among maternal factors, urban residence (AOR: 0.26, 95%CI: 0.1, 0.5), antenatal care attendance (AOR: 0.32, 95%CI: 0.2, 0.6), spontaneous vaginal delivery (AOR: 0.047, 95%CI: 0.01, 0.2), and maternal antibiotic use (AOR: 0.39; 95%CI: 0.2, 0.8) were found to have significant association with neonatal sepsis. Conclusion Overall, the magnitude of neonatal sepsis was high. Provision of neonatal and obstetrics care as per standard during prenatal, intranatal, and postnatal periods is needed. Training of health professionals on infection prevention and safe delivery practice should be provided.

Effect of community-based newborn care implementation strategies on access to and effective coverage of possible serious bacterial infection (PSBI) treatment for sick young infants during COVID-19 pandemic. PLoS One 2024; 19:e0300880. [PMID: 38527000 PMCID: PMC10962833 DOI: 10.1371/journal.pone.0300880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Accepted: 03/06/2024] [Indexed: 03/27/2024] Open
Abstract
BACKGROUND In Ethiopia, neonatal mortality is persistently high. The country has been implementing community-based treatment of possible serious bacterial infection (PSBI) in young infants when referral to a hospital is not feasible since 2012. However, access to and quality of PSBI services remained low and were worsened by COVID-19. From November 2020 to June 2022, we conducted implementation research to mitigate the impact of COVID-19 and improve PSBI management implementation uptake and delivery in two woredas in Ethiopia. METHODS In April-May 2021, guided by implementation research frameworks, we conducted formative research to understand the PSBI management implementation challenges, including those due to the COVID-19 pandemic. Through a participatory process engaging stakeholders, we designed adaptive implementation strategies to bridge identified gaps using mechanism mapping to achieve implementation outcomes. Strategies included training and coaching, supportive supervision and mentorship, technical support units, improved supply of essential commodities, and community awareness creation about PSBI and COVID-19. We conducted cross-sectional household surveys in the two woredas before (April 2021) and after the implementation of strategies (June 2022) to measure changes in targeted outcomes. RESULTS We interviewed 4,262 and 4,082 women who gave live birth 2-14 months before data collection and identified 374 and 264 PSBI cases in April 2021 and June 2022, respectively. The prevalence of PSBI significantly decreased (p-value = 0.018) from 8.7% in April 2021 to 6.4% while the mothers' care-seeking behavior from medical care for their sick newborns increased significantly from 56% to 91% (p-value <0.01). Effective coverage of severely ill young infants that took appropriate antibiotics significantly improved from 33% [95% CI: 25.5-40.7] to 62% [95% CI: 51.0-71.6]. Despite improvements in the uptake of PSBI treatment, persisting challenges at the facility and systems levels impeded optimal PSBI service delivery and uptake, including perceived low quality of service, lack of community trust, and shortage of supplies. CONCLUSION The participatory design and implementation of adaptive COVID-19 strategies effectively improved the uptake and delivery of PSBI treatment. Support systems were critical for frontline health workers to deliver PSBI services and create a resilient community health system to provide quality PSBI care during the pandemic. Additional strategies are needed to address persistent gaps, including improvement in client-provider interactions, supply of essential drugs, and increased social mobilization strategies targeting families and communities to further increase uptake.

EClinicalMedicine 2024; 69:102463. [PMID: 38426071 PMCID: PMC10904231 DOI: 10.1016/j.eclinm.2024.102463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 01/16/2024] [Accepted: 01/17/2024] [Indexed: 03/02/2024] Open
Abstract
Background Healthcare-associated infections account for substantial neonatal in-hospital mortality. Chlorhexidine gluconate (CHG) whole body skin application could reduce sepsis by lowering bacterial colonisation density, although safety and optimal application regimen is unclear. Emollients, including sunflower oil, may independently improve skin condition, thereby reducing sepsis. We aimed to inform which concentration and frequency of CHG, with or without emollient, would best balance safety and the surrogate marker of efficacy of reduction in bacterial colonisation, to be taken forward in a future pragmatic trial evaluating clinical outcomes of sepsis and mortality. Methods In this multicentre, randomised, open-label, factorial pilot trial, neonates in two hospital sites (South Africa, Bangladesh) aged 1-6 days with gestational age ≥ 28 weeks and birthweight 1000-1999 g were randomly assigned in a factorial design stratified by site to three different concentrations of CHG (0.5%, 1%, and 2%), with or without emollient (sunflower oil) applied on working days vs alternate working days. A control arm received neither product. Caregivers were unblinded although laboratory staff were blinded to randomisation Co-primary outcomes were safety (change in neonatal skin condition score incorporating dryness, erythema, and skin breakdown) and efficacy in reducing bacterial colonisation density (change in total skin bacterial log10 CFU from randomisation to day-3 and day-8). The trial is registered at the ISRCTN registry, ISRCTN 69836999. Findings Between Apr 12 2021 and Jan 18 2022, 208 infants were randomised and 198 were included in the final analysis. Skin condition scores were low with mean 0.1 (sd = 0.3; N = 208) at baseline, 0.1 (sd = 0.3; N = 199) at day 3 and 0.1 (sd = 0.3; N = 189) at day 8, with no evidence of differences between concentration (1% CHG vs 0.5% estimate = -0.3, 95% CI = (-1.2, 0.6), p = 0.55. 2% CHG vs 0.5% CHG estimate = 0.5 (-0.4, 1.4), p = 0.30), increasing frequency (estimate = -0.4; 95% CI = (-1.1, 0.4), p = 0.33), emollient (estimate = -0.5, (-1.2, 0.3), p = 0.23) or with control (estimate = -0.9, (-2.3, 0.4), p = 0.18). Mean log10 CFU was 4.9 (sd = 3.0; N = 208) at baseline, 6.3 (sd = 3.1; N = 198) at day 3 and 8.4 (sd = 2.6; N = 183) with no evidence of differences between concentration (1% CHG vs 0.5% estimate = -0.4; 95% CI = (-1.1, 0.23); p = 0.23. 2% CHG vs 0.5% CHG estimate = 0.0 (-0.6, 0.6), p = 0.96), with increasing frequency (estimate = -0.4; 95% CI = (-0.9, 0.2); p = 0.17), with emollient (estimate = 0.4, 95% CI = (-0.2, 0.9); p = 0.18) or with control (estimate = -0.2, 95% CI = (-1.3, 0.9); p = 0.73). By day-8, overall 158/183 (86%) of neonates were colonised with Enterobacterales, and 72/183 (39%) and 69/183 (9%) with Klebsiella spp resistant to third-generation cephalosporin and carbapenems, respectively. There were no CHG-related SAEs, emollient-related SAEs, grade 3 or 4 skin scores or grade 3 or 4 hypothermias. Interpretation In this pilot trial of CHG with or without sunflower oil, no safety issues were identified, and further trials examining clinical outcomes are warranted. The relatively late start application of emollient, at a mean of 3.8 days of life, may have reduced the impact of the intervention although no subgroup effects were detected. There was no clear evidence in favour of a specific concentration of chlorhexidine, and there was rapid colonisation with Enterobacterales with frequent antimicrobial resistance, regardless of skin application regimen.

Abstract
Antimicrobial resistance increasingly complicates neonatal sepsis in a global context. Fosfomycin and amikacin are two agents being tested in an ongoing multicenter neonatal sepsis trial. Although neonatal pharmacokinetics (PKs) have been described for these drugs, the physiological variability within neonatal populations makes population PKs in this group uncertain. Physiologically-based pharmacokinetic (PBPK) models were developed in Simcyp for fosfomycin and amikacin sequentially for adult, pediatric, and neonatal populations, with visual and quantitative validation compared to observed data at each stage. Simulations were performed using the final validated neonatal models to determine drug exposures for each drug across a demographic range, with probability of target attainment (PTA) assessments. Successfully validated neonatal PBPK models were developed for both fosfomycin and amikacin. PTA analysis demonstrated high probability of target attainment for amikacin 15 mg/kg i.v. q24h and fosfomycin 100 mg/kg (in neonates aged 0-7 days) or 150 mg/kg (in neonates aged 7-28 days) i.v. q12h for Enterobacterales with fosfomycin and amikacin minimum inhibitory concentrations at the adult breakpoints. Repeat analysis in premature populations demonstrated the same result. PTA analysis for a proposed combination fosfomycin-amikacin target was also performed. The simulated regimens, tested in a neonatal sepsis trial, are likely to be adequate for neonates across different postnatal ages and gestational age. This work demonstrates a template for determining target attainment for antimicrobials (alone or in combination) in special populations without sufficient available PK data to otherwise assess with traditional pharmacometric methods.

Abstract
Background Neonatal infections are a major public health concern worldwide, particularly in low- and middle-income countries, where most of the infection-related deaths in under-five children occur. Sub-Saharan Africa has the highest mortality rates, but there is a lack of data on the incidence of sepsis from this region, hindering efforts to improve child survival. We aimed to determine the incidence of possible serious bacterial infection (PSBI) in young infants in three high-burden countries in Africa. Methods This is a secondary analysis of data from the African Neonatal Sepsis (AFRINEST) trial, conducted in the Democratic Republic of the Congo (DRC), Kenya, and Nigeria between 15 March 2012 and 15 July 2013. We recorded baseline characteristics, the incidence of PSBI (as defined by the World Health Organization), and the incidence of local infections among infants from 0-59 days after birth. We report descriptive statistics. Results The incidence of PSBI among 0-59-day-old infants across all three countries was 11.2% (95% confidence interval (CI) = 11.0-11.4). The DRC had the highest incidence of PSBI (19.0%; 95% CI = 18.2-19.8). Likewise, PSBI rates were higher in low birth weight infants (24.5%; 95% CI = 23.1-26.0) and infants born to mothers aged <20 years (14.1%; 95% CI = 13.4-14.8). The incidence of PSBI was higher among infants delivered at home (11.7%; 95% CI = 11.4-12.0). Conclusions The high burden of PSBI among young infants in DRC, Kenya, and Nigeria demonstrates the importance of addressing PSBI in improving child survival in sub-Saharan Africa to reach the Sustainable Development Goals (SDGs). These data can support government authorities, policymakers, programme implementers, non-governmental organisations, and international partners in reducing preventable under-five deaths.

Abstract
Introduction. Neonatal sepsis is the primary cause of increased newborn morbidity and mortality worldwide, particularly in developing countries. In Ethiopia, the factors of neonatal sepsis are not well understood. Therefore, the purpose of this study was to determine the factors associated with neonatal sepsis in the study area. Methods. A case-control study design was conducted among 60 cases and 120 controls. Variables with P ≤ .25 in the bivariate analysis were entered into multivariable logistic regression, and statistical significance was declared at P < .05. Result. Birth weight <2500-g (AOR = 4.05 [1.44, 11.36], number of ANC visits <3 (AOR = 4.49 [1.70, 11.86], duration of rupture of membrane ≥18 hours (AOR = 4.42; [2.02, 9.66], first minute APGAR score <7 (AOR = 3.09 [1.10, 8.70], birth at a health-center (AOR = 0.22 [0.08, 0.60]) and instrumental delivery (AOR = 0.30 [0.10, 0.88]) were factors associated with neonatal sepsis. Conclusion. Neonatal sepsis was associated with different factors like prolonged membrane rupture, birth weight, and antenatal care visits.

Abstract
Objective. The 8-sign algorithm adapted from the Young Infants Clinical Signs Study (YICSS) is widely used to identify sick infants during home visits (YICSS-home algorithm). We aimed to critically appraise the development and evidence of measurement properties, including sensibility, reliability, and validity, of the YICSS-home algorithm. Methods. Relevant studies were identified through a systematic literature search. Results. The YICSS-home algorithm has good sensibility. The algorithm demonstrated at least moderate inter-rater reliability and sensitivity ranging from 69% to 80%. However, the algorithm was developed among sick infants brought for care to a health facility and not initially developed for use by community health workers (CHWs) during home visits. Some important risk factors were omitted at item generation. Inter-CHW reliability and construct validity have not been estimated. Conclusion. Future research should build on the strengths of the YICSS-home algorithm and address its limitations to develop a new algorithm with improved predictive accuracy.

Factors influencing community-facility linkage for case management of possible serious bacterial infections among young infants in Kenya. Health Policy Plan 2024; 39:56-65. [PMID: 38029322 PMCID: PMC10775218 DOI: 10.1093/heapol/czad113] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 11/19/2023] [Accepted: 11/28/2023] [Indexed: 12/01/2023] Open
Abstract
Despite evidence showing the feasibility and acceptability of implementing the World Health Organization's guidelines on managing possible serious bacterial infection (PSBI) in Kenya, the initial implementation revealed sub-optimal community-facility referrals and follow-up of PSBI cases. This study explores facilitators and barriers of community-facility linkages in implementing PSBI guidelines in Busia and Migori counties, Kenya. We used an exploratory qualitative study design drawing on endline evaluation data from the 'COVID-19: Mitigating Neonatal Mortality' project collected between June and July 2022. Data include case narratives with caregivers of sick young infants (0-59 days old) (18), focus group discussions with community health volunteers (CHVs) (6), and in-depth interviews with facility-based providers (18). Data were analysed using an inductive thematic analysis framework. Between August 2021 and July 2022, CHVs assessed 10 187 newborns, with 1176 (12%) identified with PSBI danger signs and referred to the nearest facility, of which 820 (70%) accepted referral. Analysis revealed several factors facilitating community-facility linkage for PSBI treatment, including CHVs' relationship with community members and facilities, availability of a CHV desk and tools, use of mobile app, training and supportive supervision. However, challenges such as health system-related factors (inadequate providers, stockout of essential commodities and supplies, and lack of transport/ambulance) and individual-related factors (caregivers' refusal to take referrals) hindered community-facility linkage. Addressing common barriers and fostering positive relationships between community health workers and facilities can enhance acceptance and access to PSBI services at the community level. Combining community health workers' efforts with a mobile digital strategy can improve the efficiency of the identification, referral and tracking of PSBI cases in the community and facilitate linkage with primary healthcare facilities.

Abstract
The role of gut microbiome in health, a century-old concept, has been on the center stage of medical research recently. While different body sites, disease conditions, and populations have been targeted, neonatal and early infancy appear to be the most suitable period for such interventions. It is intriguing to note that, unlike traditional use in diarrhea and maintenance of gastrointestinal health, microbiome-mediating therapies have now addressed the most serious medical conditions in young infants such as necrotizing enterocolitis and neonatal sepsis. Unfortunately, almost all new endeavors in this space have been carried out in the Western world leaving behind millions of neonates that can benefit from such manipulations while serving as a large resource for further learning. In this review, an attempt has been made to quantify the global burden of neonatal morbidity and mortality, examples presented on interventions that have failed as a result of drawing from studies conducted in the West, and a case made for manipulating the neonatal gut microbiome to address the biggest killers in early life. A brief comparative analysis has been made to demonstrate the differences in the gut microbiota of North and South and a large clinical trial of synbiotics conducted by our group in a South Asian setting has been presented. Although challenging, the value of conducting such global health research is introduced with an intent to invite medical scientists to engage in well-planned, scientifically robust research endeavors. This can bring about innovation while saving and serving the most vulnerable citizens now and protecting them from the negative health consequences in the later part of their lives, ultimately shaping a resilient and equitable world as pledged by 193 United Nations member countries in 2015.

Abstract
BACKGROUND Neonatal sepsis is an invasive infection of the bloodstream in neonates and a leading cause of morbidity and mortality among them. AIM To investigate the role of procalcitonin (PCT) and C-reactive protein (CRP) in the management of neonatal sepsis. MATERIALS AND METHODS This was a prospective case-control study over one-year period using convenience sampling. Blood samples for PCT and CRP were taken from all neonates, while blood culture and white blood cell count samples were additionally taken from babies with neonatal sepsis. PCT and CRP were repeated at 24 and 48 hours. The continuous variables were found to have a nonparametric distribution. They were presented as median and interquartile range, and compared using Wilcoxon signed rank and Friedman test as appropriate. RESULTS The blood culture analysis yielded a prevalence of 12.7% with Staphylococcus aureus being the commonest organism. Baseline concentrations of PCT (1.28 ng/ml) and CRP (17.31 mg/L) in neonates with sepsis were higher than that of controls (PCT-0.63 ng/ml, CRP-5.40 mg/L). PCT concentrations decreased after two days of antibiotic treatment, while CRP concentrations decreased after a day. The concentration of both decreased to normal levels after two days of treatment. CONCLUSION This study showed that CRP was more reliable in monitoring antibiotic therapy, unlike other studies which suggested PCT. In cases where the management of neonatal sepsis may be limited by a low blood culture yield, therapeutic monitoring may be aided by CRP and/or PCT.

Abstract
BACKGROUND Intensive care units are units where healthcare-associated infections (HAIs) are common and antimicrobial resistance rates are increasing. Microbial contamination in hospital environment plays an important role in the development of HAIs. Intervention-based improvements in infection prevention and control at national and facility level are critical for the containment of antimicrobial resistance and prevention of HAIs. OBJECTIVES This study aimed to determine the distribution of multidrug-resistant and carbapenemase-producing critical gram negative bacteria (Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Acinetobacter species) and their antibiotic resistance in intensive care unit environmental surfaces at the University of Gondar and Felege Hiwot Comprehensive Specialized Hospitals. METHODS This was multicenter hospital-based cross sectional study. Environmental samples were swabbed from all intensive care units using a normal saline moistened-sterile cotton tip stick. Bacteria culturing and antibiotic susceptibility testing were performed following standard microbiological techniques. Selected meropenem-resistant isolates were phenotypically assessed for carbapenemase production using modified and simplified carbapenem inactivation methods. RESULTS From a total of 384 environmental samples analyzed, 126 (32.8%) showed growth and 162 isolates were identified. K. pneumoniae (79/162, 48.8%) was the commonest isolate followed by Acinetobacter species (51/162, 31.5%), E. coli (19/162, 11.7%) and P. aeruginosa (13/162, 8.0%). Multidrug-resistant and carbapenemase-producing isolates were detected on most hospital environment surface types, especially from the baby bed sets and incubators. The most common multidrug-resistant and principal carbapenemase producer was K. pneumoniae, with rates of 71(89.9%) and 24(85.7%), respectively. CONCLUSION This study revealed the distribution of multidrug-resistant and carbapenemase-producing critical gram negative bacteria in the environment of intensive care unit. Higher detection rate of multidrug-resistant and carbapenemase-producing K. pneumoniae on most environmental surfaces calls for urgent control action and further attention.

Abstract
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.

Abstract
Background Neonatal sepsis is a significant contributor to neonatal morbidity and mortality worldwide. It is more prevalent in developing countries. Thus, understanding the risk factors for neonatal sepsis is critical to minimizing the incidence of infection, particularly in Ethiopia. The purpose of this study was to identify the risk factors for neonatal sepsis in neonates admitted to neonatal intensive care units of public hospitals in Southeast Ethiopia in 2020. Method An institution-based, retrospective unmatched case-control study was conducted on 97 cases and 194 controls in neonatal intensive care units of public hospitals in Southeast Ethiopia. A pretested, structured questionnaire was used to collect the data. Data was entered using EpiData 3.1 and analyzed using SPSS version 23. Bivariable and multivariable logistic regression analyses were performed to identify associated factors. An adjusted odds ratio with a 95% confidence interval was used to determine the degree of association, and statistical significance was declared at a p value of < 0.05. Results In this study, 97 cases and 194 controls were included. About two-thirds (63.9%) of cases were with early onset neonatal sepsis (<7 days). Mode of delivery with spontaneous vaginal delivery (AOR:5.032; 95% CI (1.887-13.418)), type of birth attendant (traditional birth attendant) (AOR: 4.407 95% CI (1.213,16.004)), history of STI/UTI (AOR:2.543; 95% CI (1.313,4.925)), intrapartum fever (AOR:4.379; 95% CI (2.170,8.835)), APGAR score at the 5thminute < 7 (AOR:4.832; 95% CI (1.862,12.537)), neonate received resuscitation (AOR:3.830; 95% CI (1.753,8.369)), low birth weight (AOR:6.101; 95% CI (2.124,17.525)) were the identified risk factors for neonatal sepsis. Conclusion Both maternal and neonatal factors contribute to the risk of neonatal sepsis. Spontaneous vaginal delivery, birth attended by the traditional birth attendant, history of STI/UTI, presence of intrapartum fever, low APGAR score at the 5th minute, neonate receiving resuscitation, and low birth weight were identified as independent risk factors for neonatal sepsis. Prompt identification of the aforementioned factors and management should be sought for all newborns.

Abstract
Refractory septic shock is associated with a high risk of death. Circulatory support in the form of veno-arterial extracorporeal membrane oxygenation (VA ECMO) may function as a bridge to recovery, allowing for the treatment of the source of the sepsis. Whilst VA ECMO has been accepted as the means of hemodynamic support for children, in adults, single center observational studies show survival rates of only 70-90% for hypodynamic septic shock. The use of VA ECMO for circulatory support in hyperdynamic septic shock with preserved cardiac output or when applied late during cardio-pulmonary resuscitation is not recommended. With unresolving septic shock and a loss of ventriculo-arterial coupling, stress cardiomyopathy often develops. If the cardiac index (CI) approaches subnormal levels (CI < 2.5 L/min m-2) that do not match low systemic vascular resistance with a resulting loss of vital systemic perfusion pressure, VA ECMO support should be considered. A further decrease to the level of cardiogenic shock (CI < 1.8 L/min m-2) should be regarded as an indication for VA ECMO insertion. For patients who maintain a normal-to-high CI as part of their refractory vasoparalysis, VA ECMO support is justified in children and possibly in patients with a low body mass index. Extracorporeal support for septic shock should be limited to high-volume ECMO centers.

Incidence and risk factors of neonatal bacterial infections: a community-based cohort from Madagascar (2018-2021). BMC Infect Dis 2023; 23:658. [PMID: 37798644 PMCID: PMC10552278 DOI: 10.1186/s12879-023-08642-w] [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: 12/23/2022] [Accepted: 09/25/2023] [Indexed: 10/07/2023] Open
Abstract
BACKGROUND Few studies on neonatal severe bacterial infection are available in LMICs. Data are needed in these countries to prioritize interventions and decrease neonatal infections which are a primary cause of neonatal mortality. The BIRDY project (Bacterial Infections and Antimicrobial Drug Resistant among Young Children) was initially conducted in Madagascar, Senegal and Cambodia (BIRDY 1, 2012-2018), and continued in Madagascar only (BIRDY 2, 2018-2021). We present here the BIRDY 2 project whose objectives were (1) to estimate the incidence of neonatal severe bacterial infections and compare these findings with those obtained in BIRDY 1, (2) to identify determinants associated with severe bacterial infection and (3) to specify the antibiotic resistance pattern of bacteria in newborns. METHODS The BIRDY 2 study was a prospective community-based mother and child cohort, both in urban and semi-rural areas. All pregnant women in the study areas were identified and enrolled. Their newborns were actively and passively followed-up from birth to 3 months. Data on clinical symptoms developed by the children and laboratory results of all clinical samples investigated were collected. A Cox proportional hazards model was performed to identify risk factors associated with possible severe bacterial infection. FINDINGS A total of 53 possible severe bacterial infection and 6 confirmed severe bacterial infection episodes were identified among the 511 neonates followed-up, with more than half occurring in the first 3 days. For the first month period, the incidence of confirmed severe bacterial infection was 11.7 per 1,000 live births indicating a 1.3 -fold decrease compared to BIRDY 1 in Madagascar (p = 0.50) and the incidence of possible severe bacterial infection was 76.3, indicating a 2.6-fold decrease compared to BIRDY 1 in Madagascar (p < 0.001). The 6 severe bacterial infection confirmed by blood culture included 5 Enterobacterales and one Enterococcus faecium. The 5 Enterobacterales were extended-spectrum β-lactamases (ESBL) producers and were resistant to quinolones and gentamicin. Enterococcus faecium was sensitive to vancomycin but resistant to amoxicillin and to gentamicin. These pathogns were classified as multidrug-resistant bacteria and were resistant to antibiotics recommended in WHO guidelines for neonatal sepsis. However, they remained susceptible to carbapenem. Fetid amniotic fluid, need for resuscitation at birth and low birth weight were associated with early onset possible severe bacterial infection. CONCLUSION Our results suggest that the incidence of severe bacterial infection is still high in the community of Madagascar, even if it seems lower when compared to BIRDY 1 estimates, and that existing neonatal sepsis treatment guidelines may no longer be appropriate in Madagascar. These results motivate to further strengthen actions for the prevention, early diagnosis and case management during the first 3 days of life.

Abstract
The microbiome encompasses the genomes of the microorganisms that inhabit specific environments. One Health is an emerging concept, recognised as a cohesive, harmonising approach aimed at sustainably improving the well-being of humans, animals, and the environment. The microbiome plays a crucial role in the One Health domain, facilitating interactions among humans, animals, and the environment, along with co-evolution, co-development, co-metabolism, and co-regulation with their associated humans and animals. In addition, the microbiome regulates environmental health through interactions with plant microbiota, which actively participate in substance cycling (particularly the carbon and nitrogen cycles) and influence the overall energy flow in the biosphere. Moreover, antibiotic resistance genes present in microbiota can lead to widespread drug resistance in both humans and animals. This review explores the impact of the microbiome on humans, animals, and the environment, highlighting the significance of focusing on this field in One Health research.

How long should young infants less than two months of age with moderate-mortality-risk signs of possible serious bacterial infection be hospitalised for? Study protocol for a randomised controlled trial from low- and middle-income countries. J Glob Health 2023; 13:04056.

Abstract
Background Hospitalisation and a seven-day injectable antibiotics course are recommended by the World Health Organization (WHO) to treat suspected clinical neonatal sepsis / possible serious bacterial infection (PSBI). Some infants presenting with PSBI signs associated with a moderate risk of mortality may only need a two-day hospitalisation followed by outpatient care treatment with oral antibiotics to complete seven days of antibiotics. Methods A multi-centre, individually randomised, open-label trial will be conducted in seven sites in six countries: Bangladesh, Ethiopia, India (two sites), Nigeria, Pakistan and Tanzania. A common protocol will be used with the same study design, including the participants, intervention, comparison, outcomes, quality control, and analysis procedures. 0-59 days old infants presenting with moderate-mortality risk signs (low body temperature (<35.5°C), movement only when stimulated, stopped feeding well) or two or more signs of clinical severe infection (CSI) will be assessed and pre-enrolled. After 48 hours of hospital stay, clinically stable infants with a negative C-reactive protein test will be randomised either to hospital discharge on oral amoxicillin (intervention) or continued hospitalisation (control) arm. The intervention arm will receive oral amoxicillin for five days, whereas the control arm will receive injection gentamicin plus injection ampicillin for five more days plus supportive therapy if needed. We plan to enrol 5250 eligible young infants, 2625 infants in each of the two study arms. An experienced, well-trained independent outcome assessor will visit all enrolled cases on days 4, 8 and 15 after the initiation of treatment to assess the study outcomes in both intervention and control arms. The primary outcome of poor clinical outcome defined as death between randomisation and day 15 of initiation of treatment, deterioration during the 7-day treatment period, or persistence of the presenting sign of CSI at the end of the 7-day treatment period will be compared to assess if an early discharge and outpatient treatment leads to superior or at least non-inferior clinical outcome than continued inpatient treatment. The harmonisation of activities, including methods and processes, will be carried out diligently. Central training will be conducted by the WHO coordinating team, a central data coordination centre to collate all data, standardisation exercises for all clinical signs and internal and external monitoring. All the selected sites have extensive research experience. Through regular online and physical meetings, data-based monitoring, and physical site visits by WHO monitors, quality assurance and harmonisation will be ensured. This trial has been approved by the WHO and local site institutional ethics committees. Discussion If the results show that young infants with moderate-mortality risk PSBI signs can be safely and effectively treated on an outpatient basis after a shorter hospital stay, it will reduce the burden on the hospitals, potentially reduce nosocomial hospital infections and increase access to treatment for families with poor access to health facilities. It may also reduce the health system costs (human and materials) and allow the overburdened hospitals to pay more attention to critically ill young infants. In addition, this evidence will contribute to making a case for reviewing the WHO PSBI guideline. Registration International Standard Randomised Controlled Trial Number, ISRCTN16872570.

Abstract
Background Neonatal sepsis is a major public health problem worldwide. It is one of the leading causes of neonatal mortality and morbidity worldwide. The neonatal mortality rate is higher in developing countries, where the extent and causes of neonatal sepsis are not yet known. Neonatal sepsis is a leading cause of neonatal mortality in Ethiopia. As a result, this study aimed to assess the proportion and identify maternal and neonatal risk factors for neonatal sepsis among neonates admitted to the neonatal intensive care unit. Methods An institutional-based cross-sectional study was conducted from May 2022 to July 2022 at the Wachemo University Comprehensive Specialized Teaching Hospital, Neonatal Intensive Care Unit, southern Ethiopia. A total of 205 neonates with indexed mothers participated in the study. Using a consecutive sampling technique, a structured, pretested questionnaire was used to collect data from the study subjects. Data were entered into EpiData Manager version 3.1 for Windows and then exported to SPSS version 22 for further data cleaning and analysis. Descriptive analyses were performed by using frequency, percentage, and summary statistics to describe the key variables. A multivariate regression model was used to identify factors associated with neonatal sepsis. Finally, statistical significance was declared at a p-value of less than 0.05, and an adjusted odds ratio (AOR) with a 95% confidence level was used to declare the variable's association with the outcome variable. Result The overall prevalence rate of neonatal sepsis was 39.5% (95% CI: 33.7-45.9). Multivariable analysis was performed by taking a variable that is statistically significant in bivariate logistic regression as a candidate variable. Multivariable model analysis showed that unmarried status AOR = 18.37 (95% CI: 1.56-216.14), maternal fever during delivery AOR = 4.74 (95% CI: 1.63-13.8), and premature rupture of membrane AOR = 7.53 (95% CI: 2.19-25.6) were variables that increased the odds of developing neonatal sepsis. Conclusion The study's findings indicate that neonatal sepsis is highly prevalent. Unmarried maternal status, maternal fever during delivery, and premature rupture of the membrane were predictors of neonatal sepsis. Therefore, providing training for health workers and close monitoring and evaluation during obstetric and neonatal care are crucial to halt the occurrence of neonatal sepsis.

Abstract
BACKGROUND Reducing the burden of neonatal sepsis requires timely identification and initiation of suitable antibiotic treatment in primary health care (PHC) settings. Countries are encouraged to adopt simplified antibiotic regimens at the PHC level for treating sick young infants (SYI) with signs of possible serious bacterial infection (PSBI). As countries implement PSBI guidelines, more lessons on effective implementation strategies and outcome measurements are needed. We document pragmatic approaches used to design, measure and report implementation strategies and outcomes while adopting PSBI guidelines in Kenya. METHODS We designed implementation research using longitudinal mixed methods embedded in a continuous regular systematic learning and adoption of evidence in the PHC context. We synthesized formative data to co-create with stakeholders, implementation strategies to incorporate PSBI guidelines into routine service delivery for SYIs. This was followed by quarterly monitoring for learning and feedback on the effect of implementation strategies, documented lessons learned and tracked implementation outcomes. We collected endline data to measure the overall effect on service level outcomes. RESULTS Our findings show that characterizing implementation strategies and linking them with implementation outcomes, helps illustrate the pathway between the implementation process and outcomes. Although we have demonstrated that it is feasible to implement PSBI in PHC, effective investment in continuous capacity strengthening of providers through blended approaches, efficient use of available human resources, and improving the efficiency of service areas for managing SYIs optimizes timely identification and management of SYI. Sustained provision of commodities for management of SYI facilitates increased uptake of services. Strengthening facility-community linkages supports adherence to scheduled visits. Enhancing the caregiver's preparedness during postnatal contacts in the community or facility will facilitate the effective completion of treatment. CONCLUSION Careful design, and definition of terms related to the measurement of implementation outcomes and strategies enable ease of interpretation of findings. Using the taxonomy of implementation outcomes help frame the measurement process and provides empirical evidence in a structured way to demonstrate causal relationships between implementation strategies and outcomes. Using this approach, we have illustrated that the implementation of simplified antibiotic regimens for treating SYIs with PSBI in PHC settings is feasible in Kenya.

Abstract
BACKGROUND There is limited data on antibiotic treatment in hospitalized neonates in low- and middle-income countries (LMICs). We aimed to describe patterns of antibiotic use, pathogens, and clinical outcomes, and to develop a severity score predicting mortality in neonatal sepsis to inform future clinical trial design. METHODS AND FINDINGS Hospitalized infants <60 days with clinical sepsis were enrolled during 2018 to 2020 by 19 sites in 11 countries (mainly Asia and Africa). Prospective daily observational data was collected on clinical signs, supportive care, antibiotic treatment, microbiology, and 28-day mortality. Two prediction models were developed for (1) 28-day mortality from baseline variables (baseline NeoSep Severity Score); and (2) daily risk of death on IV antibiotics from daily updated assessments (NeoSep Recovery Score). Multivariable Cox regression models included a randomly selected 85% of infants, with 15% for validation. A total of 3,204 infants were enrolled, with median birth weight of 2,500 g (IQR 1,400 to 3,000) and postnatal age of 5 days (IQR 1 to 15). 206 different empiric antibiotic combinations were started in 3,141 infants, which were structured into 5 groups based on the World Health Organization (WHO) AWaRe classification. Approximately 25.9% (n = 814) of infants started WHO first line regimens (Group 1-Access) and 13.8% (n = 432) started WHO second-line cephalosporins (cefotaxime/ceftriaxone) (Group 2-"Low" Watch). The largest group (34.0%, n = 1,068) started a regimen providing partial extended-spectrum beta-lactamase (ESBL)/pseudomonal coverage (piperacillin-tazobactam, ceftazidime, or fluoroquinolone-based) (Group 3-"Medium" Watch), 18.0% (n = 566) started a carbapenem (Group 4-"High" Watch), and 1.8% (n = 57) a Reserve antibiotic (Group 5, largely colistin-based), and 728/2,880 (25.3%) of initial regimens in Groups 1 to 4 were escalated, mainly to carbapenems, usually for clinical deterioration (n = 480; 65.9%). A total of 564/3,195 infants (17.7%) were blood culture pathogen positive, of whom 62.9% (n = 355) had a gram-negative organism, predominantly Klebsiella pneumoniae (n = 132) or Acinetobacter spp. (n = 72). Both were commonly resistant to WHO-recommended regimens and to carbapenems in 43 (32.6%) and 50 (71.4%) of cases, respectively. MRSA accounted for 33 (61.1%) of 54 Staphylococcus aureus isolates. Overall, 350/3,204 infants died (11.3%; 95% CI 10.2% to 12.5%), 17.7% if blood cultures were positive for pathogens (95% CI 14.7% to 21.1%, n = 99/564). A baseline NeoSep Severity Score had a C-index of 0.76 (0.69 to 0.82) in the validation sample, with mortality of 1.6% (3/189; 95% CI: 0.5% to 4.6%), 11.0% (27/245; 7.7% to 15.6%), and 27.3% (12/44; 16.3% to 41.8%) in low (score 0 to 4), medium (5 to 8), and high (9 to 16) risk groups, respectively, with similar performance across subgroups. A related NeoSep Recovery Score had an area under the receiver operating curve for predicting death the next day between 0.8 and 0.9 over the first week. There was significant variation in outcomes between sites and external validation would strengthen score applicability. CONCLUSION Antibiotic regimens used in neonatal sepsis commonly diverge from WHO guidelines, and trials of novel empiric regimens are urgently needed in the context of increasing antimicrobial resistance (AMR). The baseline NeoSep Severity Score identifies high mortality risk criteria for trial entry, while the NeoSep Recovery Score can help guide decisions on regimen change. NeoOBS data informed the NeoSep1 antibiotic trial (ISRCTN48721236), which aims to identify novel first- and second-line empiric antibiotic regimens for neonatal sepsis.

Global, regional, and national estimates of the impact of a maternal Klebsiella pneumoniae vaccine: A Bayesian modeling analysis. PLoS Med 2023; 20:e1004239. [PMID: 37216371 DOI: 10.1371/journal.pmed.1004239] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Accepted: 04/26/2023] [Indexed: 05/24/2023] Open
Abstract
BACKGROUND Despite significant global progress in reducing neonatal mortality, bacterial sepsis remains a major cause of neonatal deaths. Klebsiella pneumoniae (K. pneumoniae) is the leading pathogen globally underlying cases of neonatal sepsis and is frequently resistant to antibiotic treatment regimens recommended by the World Health Organization (WHO), including first-line therapy with ampicillin and gentamicin, second-line therapy with amikacin and ceftazidime, and meropenem. Maternal vaccination to prevent neonatal infection could reduce the burden of K. pneumoniae neonatal sepsis in low- and middle-income countries (LMICs) but the potential impact of vaccination remains poorly quantified. We estimated the potential impact of such vaccination on cases and deaths of K. pneumoniae neonatal sepsis and project the global effects of routine immunization of pregnant women with the K. pneumoniae vaccine as antimicrobial resistance (AMR) increases. METHODS AND FINDINGS We developed a Bayesian mixture-modeling framework to estimate the effects of a hypothetical K. pneumoniae maternal vaccine with 70% efficacy administered with coverage equivalent to that of the maternal tetanus vaccine on neonatal sepsis infections and mortality. To parameterize our model, we used data from 3 global studies of neonatal sepsis and/or mortality-with 2,330 neonates who died with sepsis surveilled from 2016 to 2020 undertaken in 18 mainly LMICs across all WHO regions (Ethiopia, Kenya, Mali, Mozambique, Nigeria, Rwanda, Sierra Leone, South Africa, Uganda, Brazil, Italy, Greece, Pakistan, Bangladesh, India, Thailand, China, and Vietnam). Within these studies, 26.95% of fatal neonatal sepsis cases were culture-positive for K. pneumoniae. We analyzed 9,070 K. pneumoniae genomes from human isolates gathered globally from 2001 to 2020 to quantify the temporal rate of acquisition of AMR genes in K. pneumoniae isolates to predict the future number of drug-resistant cases and deaths that could be averted by vaccination. Resistance rates to carbapenems are increasing most rapidly and 22.43% [95th percentile Bayesian credible interval (CrI): 5.24 to 41.42] of neonatal sepsis deaths are caused by meropenem-resistant K. pneumoniae. Globally, we estimate that maternal vaccination could avert 80,258 [CrI: 18,084 to 189,040] neonatal deaths and 399,015 [CrI: 334,523 to 485,442] neonatal sepsis cases yearly worldwide, accounting for more than 1.49% [CrI: 0.33 to 3.51] of all neonatal deaths. The largest relative benefits are in Africa (Sierra Leone, Mali, Niger) and South-East Asia (Bangladesh) where vaccination could avert over 5% of all neonatal deaths. Nevertheless, our modeling only considers country-level trends in K. pneumoniae neonatal sepsis deaths and is unable to consider within-country variability in bacterial prevalence that may impact the projected burden of sepsis. CONCLUSIONS A K. pneumoniae maternal vaccine could have widespread, sustained global benefits as AMR in K. pneumoniae continues to increase.

Abstract
Group B streptococcal (GBS) infection is one of the leading causes of neonatal sepsis worldwide. Despite a significant decline in early-onset (EOS) sepsis due to intrapartum antibiotic prophylaxis, the incidence of late-onset (LOS) infection has remained unchanged. However, LOS GBS sepsis affecting twins is very rare. We report on preterm twins born at 29 weeks of gestation: Twin B was 31 days old when he developed LOS GBS sepsis and meningitis, and Twin A was 35 days old when he developed LOS GBS sepsis. Tests for maternal GBS colonization in breast milk were negative. Both babies were treated with antibiotics and eventually discharged without complications.

Analytical and Non-Analytical Variation May Lead to Inappropriate Antimicrobial Dosing in Neonates: An In Silico Study. Clin Chem 2023:7146664.

Abstract
BACKGROUND Therapeutic drug monitoring (TDM) of aminoglycosides and vancomycin is used to prevent oto- and nephrotoxicity in neonates. Analytical and nonanalytical factors potentially influence dosing recommendations. This study aimed to determine the impact of analytical variation (imprecision and bias) and nonanalytical factors (accuracy of drug administration time, use of non-trough concentrations, biological variation, and dosing errors) on neonatal antimicrobial dosing recommendations. METHODS Published population pharmacokinetic models and the Australasian Neonatal Medicines Formulary were used to simulate antimicrobial concentration-time profiles in a virtual neonate population. Laboratory quality assurance data were used to quantify analytical variation in antimicrobial measurement methods used in clinical practice. Guideline-informed dosing recommendations based on drug concentrations were applied to compare the impact of analytical variation and nonanalytical factors on antimicrobial dosing. RESULTS Analytical variation caused differences in subsequent guideline-informed dosing recommendations in 9.3-12.1% (amikacin), 16.2-19.0% (tobramycin), 12.2-45.8% (gentamicin), and 9.6-19.5% (vancomycin) of neonates. For vancomycin, inaccuracies in drug administration time (45.6%), use of non-trough concentrations (44.7%), within-subject biological variation (38.2%), and dosing errors (27.5%) were predicted to result in more dosing discrepancies than analytical variation (12.5%). Using current analytical performance specifications, tolerated dosing discrepancies would be up to 14.8% (aminoglycosides) and 23.7% (vancomycin). CONCLUSIONS Although analytical variation can influence neonatal antimicrobial dosing recommendations, nonanalytical factors are more influential. These result in substantial variation in subsequent dosing of antimicrobials, risking inadvertent under- or overexposure. Harmonization of measurement methods and improved patient management systems may reduce the impact of analytical and nonanalytical factors on neonatal antimicrobial dosing.

Abstract
BACKGROUND The objective was to achieve high coverage of possible serious bacterial infections (PSBI) treatment using the World Health Organization (WHO) guideline for managing it on an outpatient basis when referral to a hospital is not feasible. METHODS We implemented this guideline in the programme settings at 10 Basic Health Units (BHU) in two rural districts of Sindh in Pakistan using implementation research. A Technical Support Unit supported the programme to operationalize guidelines, built capacity of health workers through training, monitored their clinical skills, mentored them and assured quality. The community-based health workers visited households to identify sick infants and referred them to the nearest BHU for further management. The research team collected data. RESULTS Of 17 600 identified livebirths, 1860 young infants with any sign of PSBI sought care at BHUs and 1113 (59.8%) were brought by families. We achieved treatment coverage of 95%, assuming an estimated 10% incidence of PSBI in the first 2 months of life and that 10% of young infants came from outside the study catchment area. All 923 infants (49%; 923/1860) 7-59 days old with only fast breathing (pneumonia) treated with outpatient oral amoxicillin were cured. Hospital referral was refused by 83.4% (781/937) families who accepted outpatient treatment; 92.2% (720/781) were cured and 0.8% (6/781) died. Twelve (7.6%; 12/156) died among those treated in a hospital. CONCLUSION It is feasible to achieve high coverage by implementing WHO PSBI management guidelines in a programmatic setting when a referral is not feasible.

Abstract
BACKGROUND Treatment of neonatal peritonitis and sepsis is challenging. Following infection, neutrophils elaborate neutrophil extracellular traps (NETs)-extracellular lattices of decondensed chromatin decorated with antimicrobial proteins. NETs, however, can augment pathogenic inflammation causing collateral damage. We hypothesized that NET inhibition would improve survival in experimental neonatal infectious peritonitis. METHODS We induced peritonitis in 7 to 10-day-old mice by intraperitoneal injection with cecal slurry. We targeted NETs by treating mice with neonatal NET-Inhibitory Factor (nNIF), an endogenous NET-inhibitor; Cl-amidine, a PAD4 inhibitor; DNase I, a NET degrading enzyme, or meropenem (an antibiotic). We determined peritoneal NET and cytokine levels and circulating platelet-neutrophil aggregates. Survival from peritonitis was followed for 6 days. RESULTS nNIF, Cl-amidine, and DNase I decreased peritoneal NET formation and inflammatory cytokine levels at 24 h compared to controls. nNIF, Cl-amidine, and DNase I decreased circulating platelet-neutrophil aggregates, and NET-targeting treatments significantly increased survival from infectious peritonitis compared to controls. Finally, nNIF administration significantly improved survival in mice treated with sub-optimal doses of meropenem even when treatment was delayed until 2 h after peritonitis induction. CONCLUSIONS NET inhibition improves survival in experimental neonatal infectious peritonitis, suggesting that NETs participate pathogenically in neonatal peritonitis and sepsis. IMPACT 1. Neutrophil extracellular trap formation participates pathogenically in experimental neonatal infectious peritonitis. 2. NET-targeting strategies improve outcomes in a translational model of neonatal infectious peritonitis. 3. NET inhibition represents a potential target for drug development in neonatal sepsis and infectious peritonitis.

Maternal colonization and early-onset neonatal bacterial sepsis in the Gambia, West Africa: a genomic analysis of vertical transmission. Clin Microbiol Infect 2023; 29:386.e1-386.e9.

Abstract
OBJECTIVES To define bacterial aetiology of neonatal sepsis and estimate the prevalence of neonatal infection from maternal genital tract bacterial carriage among mother-newborn pairs. METHODS We carried out a cross-sectional study of newborns with clinical sepsis admitted to three hospitals in the Gambia neonatal wards. Neonatal blood cultures and maternal genital swabs were obtained at recruitment. We used whole-genome sequencing to explore vertical transmission for neonates with microbiologically confirmed bloodstream infection by comparing phenotypically-matched paired neonatal blood cultures and maternal genital tract bacterial isolates. RESULTS We enrolled 203 maternal-newborn pairs. Two-thirds (67%; 137/203) of neonates presented with early-onset sepsis (days 0-6 after birth) of which 26% (36/137) were because of a clinically-significant bacterial pathogen. Blood culture isolates from newborns with early-onset sepsis because of Staphylococcus aureus (n = 5), Klebsiella pneumonia (n = 2), and Enterococcus faecalis (n = 1), phenotypically matched their maternal genital tract isolates. Pairwise single-nucleotide variants comparisons showed differences of 12 to 52 single-nucleotide variants only between maternal and newborn S. aureus isolates, presumably representing vertical transmission with a transmission rate of 14% (5/36). CONCLUSIONS We found a low prevalence of vertical transmission of maternal genital tract colonization in maternal-newborn pairs for early-onset neonatal sepsis in the West African context. Identifying infection acquisition pathways among newborns is essential to prioritize preventive interventions, which could be targeted at the mother or infection control in the hospital environment, depending on the major pathways of transmission.

Molecular surveillance reveals widespread colonisation by carbapenemase and extended spectrum beta-lactamase producing organisms in neonatal units in Kenya and Nigeria. Antimicrob Resist Infect Control 2023; 12:14. [PMID: 36814315 PMCID: PMC9945588 DOI: 10.1186/s13756-023-01216-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 02/13/2023] [Indexed: 02/24/2023] Open
Abstract
OBJECTIVES Neonatal sepsis, a major cause of death amongst infants in sub-Saharan Africa, is often gut derived. Gut colonisation by Enterobacteriaceae producing extended spectrum beta-lactamase (ESBL) or carbapenemase enzymes can lead to antimicrobial-resistant (AMR) or untreatable infections. We sought to explore the rates of colonisation by ESBL or carbapenemase producers in two neonatal units (NNUs) in West and East Africa. METHODS Stool and rectal swab samples were taken at multiple timepoints from newborns admitted to the NNUs at the University College Hospital, Ibadan, Nigeria and the Jaramogi Oginga Odinga Teaching and Referral Hospital, Kisumu, western Kenya. Samples were tested for ESBL and carbapenemase genes using a previously validated qPCR assay. Kaplan-Meier survival analysis was used to examine colonisation rates at both sites. RESULTS In total 119 stool and rectal swab samples were taken from 42 infants admitted to the two NNUs. Colonisation with ESBL (37 infants, 89%) was more common than with carbapenemase producers (26, 62.4%; P = 0.093). Median survival time before colonisation with ESBL organisms was 7 days and with carbapenemase producers 16 days (P = 0.035). The majority of ESBL genes detected belonged to the CTX-M-1 (36/38; 95%), and CTX-M-9 (2/36; 5%) groups, and the most prevalent carbapenemase was blaNDM (27/29, 93%). CONCLUSIONS Gut colonisation of neonates by AMR organisms was common and occurred rapidly in NNUs in Kenya and Nigeria. Active surveillance of colonisation will improve the understanding of AMR in these settings and guide infection control and antibiotic prescribing practice to improve clinical outcomes.

Microbiol Spectr 2022; 10:e0119522. [PMID: 36409152 PMCID: PMC9769891 DOI: 10.1128/spectrum.01195-22] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 10/28/2022] [Indexed: 11/23/2022] Open
Abstract
Infectious diseases pose a fatal risk to neonates. Timely and accurate pathogen detection is crucial for proper clinical diagnosis and therapeutic strategies. Limited sample volumes from neonatal patients seriously hindered the accurate detection of pathogens. Here, we unravel that metagenomic next-generation sequencing (mNGS) of cell-free DNA (cfDNA) and RNA can achieve unbiased detection of trace pathogens from different kinds of body fluid samples and blood samples. We enrolled 168 neonatal patients with suspected infections from whom blood samples (n = 153), cerebrospinal fluid samples (n = 127), and respiratory tract samples (RTSs) (including bronchoalveolar lavage fluids, sputa, and respiratory secretions) (n = 51) were collected and analyzed using mNGS. High rates of positivity (70.2%; 118/168) of mNGS were observed, and the coincidence rate against the final clinical diagnosis in positive mNGS cases reached 68.6% (81/118). The most common causative pathogens were Klebsiella pneumoniae (n = 12), Escherichia coli (n = 12), and Streptococcus pneumoniae (n = 8). mNGS using cfDNA and RNA can identify microbes that cannot be detected by conventional methods in different body fluid and blood samples, and more than 50% of these microbes were identified as causative pathogens. Further local polynomial regression fitting analysis revealed that the best timing for mNGS detection ranged from 1 to 3 days after the start of continuous antimicrobial therapy. Diagnosed and guided by mNGS results, the therapeutic regimens for 86 out of 117 neonatal patients were changed, most of whom (80/86) completely recovered and were discharged, while 44 out of 86 patients completely or partially stopped unnecessary medication. Our findings highlight the importance of mNGS in detecting causative DNA and RNA pathogens in infected neonatal patients. IMPORTANCE To the best of our knowledge, this is the first report on evaluating the performance of mNGS using cfDNA and RNA from body fluid and blood samples for diagnosing neonatal infections. mNGS of RNA and cfDNA can achieve the unbiased detection and identification of trace pathogens from different kinds of neonatal body fluid and blood samples with a high total coincidence rate (226/331; 68.3%) against final clinical diagnoses by sample. The best timing for mNGS detection in neonatal infections ranged from 1 to 3 days, rather than 0 days, after the start of continuous antimicrobial therapy. Our findings highlight the importance of mNGS in detecting causative DNA and RNA pathogens, and the extensive application of mNGS for the diagnosis of neonatal infections can be expected.

Using the Implementation Research Logic Model to design and implement community-based management of possible serious bacterial infection during COVID-19 pandemic in Ethiopia. BMC Health Serv Res 2022; 22:1515. [PMID: 36514111 PMCID: PMC9745284 DOI: 10.1186/s12913-022-08945-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 12/08/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Community-based treatment of possible serious bacterial infection (PSBI) in young infants, when referral to a hospital is not possible, can result in high treatment coverage and low case fatality. However, in Ethiopia, the coverage of PSBI treatment remains low, worsened by COVID-19. To understand the challenges of delivery of PSBI treatment and design and test adaptative strategies to mitigate the impact of COVID-19 on neonatal mortality, we did implementation research (IR) employing Implementation Research Logic Model (IRLM). In this paper, we describe IRLM application experiences in designing, implementing, and evaluating strategies to improve community-based treatment of PSBI during the COVID-19 pandemic in Ethiopia. METHODS This IR was conducted between November 2020-April 2022 at Dembecha and Lume woredas of Amhara and Oromia regions, respectively. We employed narrative reviews, formative assessment and facilitated stakeholder engagement to develop the PSBI treatment IRLM to identify barriers, understand the conceptual linkages among determinants, choose implementation strategies, elicit mechanisms, and link to implementation outcomes. In addition, we used the IRLM to structure the capture of emerging implementation challenges and resulting strategy adaptations throughout implementation. RESULTS This IR identified COVID-19 and multiple pre-existing contextual factors. We designed and implemented implementation strategies to address these challenges. These adaptive strategies were implemented with sufficient strength to maintain the delivery of PSBI services and improve mothers' care-seeking behavior for their sick young infants. The IRLM offers us a clear process and path to prioritize implementation challenges, choose strategies informed by mechanisms of action, and where the adaptive implementation of community-based management of PSBI would lead to high-implementation fidelity and change in mother behavior to seek care for their sick young infants. The IRLM was also an effective tool for stakeholder engagement, easily explained and used to structure discussion and decision-making during co-design meetings. CONCLUSIONS The use of the IRLM helps us to specify the conceptual links between the implementation challenges, strategies, mechanisms of action, and outcomes to explore the complex community-based management of PSBI during complex contexts to improve high-fidelity implementation and integration of PSBI treatment in the primary healthcare delivery systems through active engagement of stakeholders.

Abstract
BACKGROUND Early onset neonatal sepsis (EONS) and late onset neonatal sepsis (LONS) are important causes of neonatal mortality and morbidity. A pressing need for reliable and detailed data of low- and middle-income countries exists. This study aimed to describe the incidence and outcome of neonatal sepsis in the only tertiary hospital of Suriname, a middle-income country in South America. METHODS Infants born at the Academic Hospital of Paramaribo from May 2017 through December 2018 were prospectively included at birth. Perinatal data, duration of antibiotic treatment, blood culture results and mortality data were gathered. Neonatal sepsis was defined as positive blood culture with a pathogenic microorganism within the first 28 days of life. RESULTS Of the 2190 infants included, 483 (22%) were admitted to neonatal (intensive) care. The incidence of EONS was 2.1 (95% CI: 0.9-5) per 1000 live births, with no deaths. Antibiotics for suspected EONS were administrated to 189 (8.6%) infants, of whom 155 (82%) were born prematurely. The incidence of LONS cases was 145 (95% CI: 114-176) per 1000 admissions. Gramnegative bacteria accounted for 70% (48 out of 70) of causative organisms. Seventeen deaths were directly caused by sepsis (35 per 1000 admissions). CONCLUSIONS Findings from this tertiary center birth cohort study in a middle-income setting indicate EONS incidence and outcomes comparable to high-income settings, whereas LONS is a more prevalent and significant challenge with a predominance of gram-negative bacteria, and high mortality.

Abstract
BACKGROUND Annual mortality from neonatal sepsis is an estimated 430 000-680 000 infants globally, most of which occur in low- and middle-income countries (LMICs). The WHO currently recommends a narrow-spectrum β-lactam (e.g. ampicillin) and gentamicin as first-line empirical therapy. However, available epidemiological data demonstrate high rates of resistance to both agents. Alternative empirical regimens are needed. Flomoxef and amikacin are two off-patent antibiotics with potential for use in this setting. OBJECTIVES To assess the pharmacodynamics of flomoxef and amikacin in combination. METHODS The pharmacodynamic interaction of flomoxef and amikacin was assessed in chequerboard assays and a 16-arm dose-ranged hollow-fibre infection model (HFIM) experiment. The combination was further assessed in HFIM experiments mimicking neonatal plasma exposures of clinically relevant doses of both drugs against five Enterobacterales isolates with a range of flomoxef/amikacin MICs. RESULTS Flomoxef and amikacin in combination were synergistic in bacterial killing in both assays and prevention of emergence of amikacin resistance in the HFIM. In the HFIM assessing neonatal-like drug exposures, the combination killed 3/5 strains to sterility, (including 2/5 that monotherapy with either drug failed to kill) and failed to kill the 2/5 strains with flomoxef MICs of 32 mg/L. CONCLUSIONS We conclude that the combination of flomoxef and amikacin is synergistic and is a potentially clinically effective regimen for the empirical treatment of neonatal sepsis in LMIC settings and is therefore suitable for further assessment in a clinical trial.
