Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is a common hospital-acquired infection in neonates on invasive mechanical ventilation, resulting in high morbidity and mortality. The objective of this study is to determine the incidence, risk factors, short-term outcomes and microbiome associated with VAP in very-low-birth-weight (VLBW) infants born at <32 weeks of gestational age (GA). METHODS Retrospective study of intubated VLBW infants born at <32 weeks of GA admitted to the Los Angeles General Medical Center neonatal intensive care unit from July 2015 to July 2021 who had routine tracheal aspirate cultures obtained. Neonates were retrospectively classified into 3 groups, confirmed VAP, suspected VAP and no VAP, for comparison of risk factors, outcomes and airway microbial colonization. RESULTS Eighty-seven infants met inclusion criteria with a mean GA of 26.1 ± 1 weeks and mean birth weight of 812 ± 281 g. The incidence of VAP was 7.8 per 1000 ventilator days, and the most common causative organisms were Gram-positive organisms (39%), predominantly coagulase-negative Staphylococcus. Duration of postnatal dexamethasone exposure predicted VAP compared to no VAP (coefficient, 0.31; 95% CI 0.03-0.59; P = 0.03) after adjusting for duration of intubation, surfactant use and antenatal steroid exposure. Infants with VAP had higher rate of grade 2/3 bronchopulmonary dysplasia (P = 0.03) and longer hospital stay (P = 0.04). CONCLUSIONS VAP occurs at a high rate in VLBW infants who are exposed to prolonged dexamethasone use. It is predominantly caused by Gram-positive organisms.

Chae S, Shon S. Effectiveness of simulation-based interprofessional education on teamwork and communication skills in neonatal resuscitation. BMC MEDICAL EDUCATION 2024; 24:602. [PMID: 38822320 PMCID: PMC11143663 DOI: 10.1186/s12909-024-05581-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 05/21/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND The role of effective interprofessional teamwork is especially vital in the Neonatal Intensive Care Unit (NICU) where infants facing emergency situations are admitted. Proper neonatal resuscitation, facilitated by comprehensive resuscitation training, can significantly decrease the mortality rates associated with neonatal asphyxia and respiratory failure. This study aimed to develop a simulation-based interprofessional education (IPE) programme for medical staff working in a nursery and NICU and to assess its effectiveness on teamwork, communication skills, clinical performance, clinical judgement, interprofessional attitudes, and education satisfaction. METHODS Through a demand survey, neonatal resuscitation was selected as the theme, and an IPE team comprised of one doctor and two nurses was formed. The education programme consisted of three sessions lasting a total of 140 min: two simulation exercises and one theoretical education session. Data were collected from 18 nurses working in the nursery and NICU and 9 doctors working in the paediatrics department. RESULTS A comparison of the metrics before and after applying simulation-based IPE programmes revealed teamwork (Z=-2.67, p = .008), communication skills (Z=-2.68, p = .007), clinical performance (Z=-2.52, p = .012), clinical judgement (Z=-4.52, p < .001), and interprofessional attitude (Z=-3.64, p < .001) to have significantly improved. Education satisfaction scores were 4.73 points on average out of a maximum of 5. The simulation-based IPE programme was effective in improving the teamwork, communication, and clinical performance of resuscitation teams, individual clinical judgement, and interprofessional attitude. CONCLUSIONS Simulation-based IPE is effective for enhancing teamwork, team communication, clinical judgement skills, and clinical performance in neonatal resuscitation. This programme has the potential to contribute to the improvement of patient safety and the quality of neonatal care. Additional studies are needed to longitudinally examine the effects of the programme on patient safety and quality of neonatal care.

Abstract
The second most prevalent healthcare-associated infection in neonatal intensive care units (NICUs) is ventilator-associated pneumonia (VAP). This review aims to update the knowledge regarding the incidence of neonatal VAP and to summarize possible strategies for prevention. The VAP incidence ranges from 1.4 to 7 episodes per 1000 ventilator days in developed countries and from 16.1 to 89 episodes per 1000 ventilator days in developing countries. This nosocomial infection is linked to higher rates of illness, death, and longer hospital stays, which imposes a substantial financial burden on both the healthcare system and families. Due to the complex nature of the pathophysiology of VAP, various approaches for its prevention in the neonatal intensive care unit have been suggested. There are two main categories of preventative measures: those that attempt to reduce infections in general (such as decontamination and hand hygiene) and those that target VAP in particular (such as VAP care bundles, head of bed elevation, and early extubation). Some of the interventions, including practicing good hand hygiene and feeding regimens, are easy to implement and have a significant impact. One of the measures that seems very promising and encompasses a lot of the preventive measures for VAP are the bundles. Some preventive measures still need to be studied.

Abstract
OBJECTIVES To determine the utility of microscopic examination and culture of endotracheal aspirate (ETA) in the early diagnosis of ventilator-associated pneumonia (VAP) in preterm neonates. METHODS We enrolled 80 consecutive neonates (both inborn and out-born) with gestational age of < 37 weeks admitted in Special Newborn Care Unit (SNCU) and requiring mechanical ventilation (MV) for ≥ 48 hours. The diagnosis of VAP was made using the criteria laid down by the Centers for Disease Control (CDC). RESULTS 47 preterm neonates (58.5%) developed VAP; the overall incidence was 74.7/1000 ventilator-days. The mean (SD) time (hours) to ETA culture was less as compared to diagnosis based on CDC criteria [108.9 (8.00 hrs) vs 132.4 (53.24); P = 0.004] with sensitivity and specificity of 80.8% and 72.7%, respectively. Outborn delivery was the single most important risk factor for VAP. Multidrug resistant (MDR) Klebsiella pneumoniae (63.9%) was the most prevalent organism. CONCLUSIONS We noticed a very high incidence of VAP among preterm neonates in SNCU. ETA culture can aid in early diagnosis.

Abstract
Ventilator-associated pneumonia (VAP) is a serious complication in neonates requiring mechanical ventilation. This study aimed to determine the risk factors associated with the development of VAP in neonates admitted to the neonatal intensive care unit (NICU) of the Affiliated Hospital of Southwest Medical University. In a retrospective observational study, neonates admitted to the NICU from 1 January 2019, to 31 December 2021, requiring ventilation for more than 48 h were included. Neonates who died within 48 h of NICU admission, those without obtainable consent, or identified with a genetic syndrome were excluded. Various neonatal and clinical variables were evaluated. Univariate and multivariate analyses were performed to determine risk factors associated with VAP. Of the total neonates included, several risk factors were identified for VAP, such as being a premature infant and use of dexamethasone and sedatives. Moreover, reintubation was found to decrease the risk of VAP. Some factors like gestational age, birth weight, Apgar scores at 5 min, and other parameters were found not significantly associated with the development of VAP. The study identified several risk factors associated with the development of VAP in neonates. Recognizing these risk factors could help in the prevention and early management of VAP, thus improving the prognosis for these patients. Further studies are needed to validate these findings and explore the mechanistic links between these factors and VAP.

Abstract
Colostrum from mothers is rich in immunomodulating bio-factors such as immunoglobulins (IgA), lactoferrin, and oligosaccharides and supports gut microbial and inflammatory processes. The support in these processes may provide some relief for infants who are born pre-term. Pre-term infants are more likely to develop necrotizing enterocolitis (NEC), late-onset sepsis (LOS), and ventilator-acquired/associated pneumonia (VAP). Due to the components of colostrum, there may be incentives towards early administration for preterm infants. An extensive literature review was done using ProQuest, ScienceDirect, and PubMed. Only meta-analyses and experimental studies were used. The search included the keywords 'colostrum and preterm' and 'colostrum and necrotizing enterocolitis'. The initial search generated 13,543 articles and was narrowed to 25 articles through comprehensive inclusion and exclusion criteria. There were significantly higher levels of Lactobacillus and Bifidobacterium in pre-term infants given colostrum and a decrease in Moraxellaceae and Staphylococcaceae. Salivary secretory IgA increased following oral colostrum administration in pre-term infants along with downregulation of interleukin (IL)-1b and IL-8. It was also observed that tumor necrosis factor (TNF)-a, and interferon-gamma (IFN-g) were significantly higher in the control group. There was no significant difference in the incidence of LOS, NEC, or VAP between pre-term infants receiving colostrum and those who did not. Secondary outcomes such as time to full enteral feeding were improved in pre-term infants receiving oral colostrum in addition to reduced hospital stays. Lastly, there was no difference in mortality between pre-term infants that received colostrum compared to those who did not.

Front Pediatr 2023; 10:1070858. [PMID: 36923947 PMCID: PMC10008901 DOI: 10.3389/fped.2022.1070858] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Accepted: 11/30/2022] [Indexed: 03/01/2023] Open
Abstract
Objective We aimed to use molecular biomarkers and clinical data and echocardiograms that were collected during admission to predict bronchopulmonary dysplasia (BPD) in preterm infants with gestational age ≤32 weeks. Methods Eighty-two patients (40 with BPD, BPD group and 42 healthy as controls, non-BPD group) admitted to the Department of Neonatology of the Children's Hospital of Soochow University between October 1, 2018, and February 29, 2020, were enrolled in this study at the tertiary hospital. Basic clinical data on the perinatal period, echocardiographic measurements, and molecular biomarkers (N-terminal-pro-B-brain natriuretic peptide, NT-proBNP) were collected. We used multiple logistic regression analysis to establish an early predictive model for detecting BPD development in preterm infants of gestational age ≤32 weeks. We also used a receiver operating characteristic curve to assess the sensitivity and specificity of the model. Results No significant differences were found between the BPD and non-BPD groups in terms of sex, birth weight, gestational age, incidence of asphyxia, maternal age, gravidity, parity, mode of delivery, premature rupture of membranes >18 h, use of prenatal hormones, placental abruption, gestational diabetes mellitus, amniotic fluid contamination, prenatal infections, and maternal diseases. The use of caffeine, albumin, gamma globulin; ventilation; days of FiO2 ≥ 40%; oxygen inhalation time; red blood cell suspension infusion volume (ml/kg); and proportion of infants who received total enteral nutrition (120 kcal/kg.d) ≥24 d after birth were higher in the BPD group than in the non-BPD group. The levels of hemoglobin, hematocrit, and albumin in the BPD group were significantly lower than those in the non-BPD group. The total calorie intake was significantly lower in the BPD group on the 3rd, 7th, and 14th day after birth than in the non-BPD group (P < 0.05). The incidence rates of patent ductus arteriosus (PDA), pulmonary hypertension, and tricuspid regurgitation were significantly higher in the BPD group than in the non-BPD group (P < 0.05). The serum level of NT-proBNP 24 h after birth was significantly higher in the BPD group than in the non-BPD group (P < 0.05). Serum NT-proBNP levels were significantly higher in infants with severe BPD than in those with mild or moderate BPD (P < 0.05). Conclusion As there were various risk factors for BPD, a combining clinical data, molecular biomarkers, and echocardiogram measurements can be valuable in predicting the BPD. The tricuspid regurgitation flow rate (m/s), NT-proBNP (pg/ml), ventilator-associated pneumonia, days of FiO2 ≥ 40% (d), red blood cell suspension infusion volume (ml/kg), and proportion of infants who received total enteral nutrition (120 kcal/kg.d) ≥24 d after birth were the most practical factors considered for designing an appropriate model for predicting the risk of BPD.

Abstract
Background Preterm birth is a major public health concern with the largest burden of morbidity and mortality falling within low- and middle-income countries (LMIC). Materials and methods This sequential explanatory mixed methods study was conducted in special care baby units (SCBUs) serving migrants and refugees along the Myanmar-Thailand border. It included a retrospective medical records review, qualitative interviews with mothers receiving care within SCBUs, and focus group discussions with health workers. Changes in neonatal mortality and four clinical outcomes were described. A mix of ethnographic phenomenology and implementation frameworks focused on cultural aspects, the lived experience of participants, and implementation outcomes related to SCBU care. Results From 2008-2017, mortality was reduced by 68% and 53% in very (EGA 28-32 weeks) and moderate (EGA 33-36 weeks) preterm neonates, respectively. Median SCBU stay was longer in very compared to moderate preterm neonates: 35 (IQR 22, 48 days) vs. 10 days (IQR 5, 16). Duration of treatments was also longer in very preterm neonates: nasogastric feeding lasted 82% (IQR 74, 89) vs. 61% (IQR 40, 76) of the stay, and oxygen therapy was used a median of 14 (IQR 7, 27) vs. 2 (IQR 1, 6) days respectively. Nine interviews were conducted with mothers currently receiving care in the SCBU and four focus group discussions with a total of 27 local SCBU staff. Analysis corroborated quantitative analysis of newborn care services in this setting and incorporated pertinent implementation constructs including coverage, acceptability, appropriateness, feasibility, and fidelity. Coverage, acceptability, and appropriateness were often overlapping outcomes of interest highlighting financial issues prior to or while admitted to the SCBU and social issues and support systems adversely impacting SCBU stays. Interview and FGD findings highlight the barriers in this resource-limited setting as they impact the feasibility and fidelity of providing evidence-based SCBU care that often required adaptation to fit the financial and environmental constraints imposed by this setting. Discussion This study provides an in-depth look at the nature of providing preterm neonatal interventions in a SCBU for a vulnerable population in a resource-limited setting. These findings support implementation of basic evidence-based interventions for preterm and newborn care globally, particularly in LMICs.

Abstract
RATIONALE An increasing number of periviable birth newborns (PVBs) have emerged with concurrent growing high-risk pregnancy. To date, postnatal management of PVBs remains one of the most challenging issues and limited studies have been reported. PATIENT CONCERNS A female baby born at 230/7 weeks of gestation with birth weight of 450g. DIAGNOSIS PVB baby, respiratory distress syndrome (RDS), ventilator associated pneumonia (VAP), intraventricular hemorrhage (IVH), metabolic bone disease of prematurity (MBDP), transient hypothyroxinemia of prematurity (THOP), bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP). INTERVENTIONS Individualized treatment and intensive care, including neonatal resuscitation, effective respiratory and circulatory support, venous access and nutrition, prevention and treatment of infection, management of endocrine and metabolic problems, individualized nursing such as developmental supportive care, integrated oral motor interventions, skin care, family-integrated-care, etc were performed according to existing literature. OUTCOMES The baby was discharged home after 138 days of hospitalization with body weight of 2700 g, a full oral feed achieved, and without any requirement of respiratory support or oxygen supply. Now she is 38-month-old, with no significant long-term adverse sequelae. LESSONS Our case expands the experience and knowledges of individualized and intensive management of PVB babies in their early life days, which increase PVBs' survival and improves their prognosis.

Abstract
BACKGROUND There are no published guidelines regarding the diagnosis and treatment of ventilator-associated tracheitis (VAT) in the neonatal intensive care unit (NICU). VAT is likely over-diagnosed and over-treated, increasing antibiotic burden and cost. LOCAL PROBLEM Diagnosis and treatment of VAT were entirely NICU provider dependent. METHODS Retrospective pre- and post-intervention chart reviews were performed. INTERVENTIONS A VAT diagnosis and treatment algorithm was created for use in the care of intubated patients without tracheostomies. 3 plan-do-study-act (PDSA) cycles were used to implement change. RESULTS Intubated patients treated for VAT with <25 PMNs on Gram stain decreased from 79% to 35% following the quality improvement (QI) initiative. Treatment of VAT with >7 days of antibiotic therapy decreased from 42% to 10%. CONCLUSION Implementing a QI initiative to improve the diagnosis and treatment of VAT in the NICU decreased the percent of patients treated inappropriately for VAT.

Abstract
Ventilator-associated pneumonia (VAP) is the second most common hospital-acquired infection (HAI) among neonatal patients in the intensive care units (ICUs) and is a serious challenge for neonatologists because it affects critically ill patients who need prolonged mechanical ventilation. In Bulgaria, there is no detailed data at regional and national levels on the characteristics of VAP in newborns, which imposes a necessity for specific studies of risk factors and etiology of VAP. The aim of the study was to analyze the frequency, characteristics and risk factors for the occurrence of VAP in newborns hospitalized in intensive care unit. This was a prospective study, conducted between January 2017 and June 2018 in the NICU of University Hospital "St. George" Plovdiv, Bulgaria. The sample consisted of 507 neonates, followed up prospectively, 107 of whom were placed on mechanical ventilation for ≥48 h. VAP was diagnosed in 33 out of 107 neonates (31%). The VAP incidence rate was 35.06/1.000 ventilator days. We confirmed differences between the median birth weight (1,310 vs. 1,690 g, p = 0.045) and average gestational age (31.08 g.w. vs. 33.08 g.w, p = 0.04) of the patients with and without VAP. The average stay of patients with VAP in the NICU was statistically significantly longer than the hospital stay of non-VAP patients (35.70 ± 21.84 days vs. 21.77 ± 17.27 days (t = 3.241, p = 0.002). In neonates with VAP, the duration of mechanical ventilation was statistically significantly longer compared with non-VAP patients (16.88 ± 11.99 vs. 5.42 ± 4.48; t = 5.249, p = 0.000). A statistically significant prevalence of Gram-negative bacteria among VAP patients was demonstrated (91%) compared to the Gram-positive (9%), p < 0.05. The leading causative agent of VAP was Klebsiella pneumoniae ESBLs + (27%), followed by Acinetobacter baumannii (14%), Pseudomonas aeruginosa (12%) and Escherichia coli (12%). In multivariate logistic regression, mechanical ventilation >7 days was established as an independent risk factor for VAP (OR 3.6; 95% CI: 1.7-6.5, p = 0.003). VAP remains a serious and outstanding issue in pediatric and neonatal intensive care units. The findings of the current study emphasize that the birth weight, gestational age, and duration of hospital stay have a significant association with ventilator-associated pneumonia.

Metabolic-endocrine disruption due to preterm birth impacts growth, body composition, and neonatal outcome. Pediatr Res 2022; 91:1350-1360.

Abstract
Despite optimized nutrition, preterm-born infants grow slowly and tend to over-accrete body fat. We hypothesize that the premature dissociation of the maternal-placental-fetal unit disrupts the maintenance of physiological endocrine function in the fetus, which has severe consequences for postnatal development. This review highlights the endocrine interactions of the maternal-placental-fetal unit and the early perinatal period in both preterm and term infants. We report on hormonal levels (including tissue, thyroid, adrenal, pancreatic, pituitary, and placental hormones) and nutritional supply and their impact on infant body composition. The data suggest that the premature dissociation of the maternal-placental-fetal unit leads to a clinical picture similar to panhypopituitarism. Further, we describe how the premature withdrawal of the maternal-placental unit, neonatal morbidities, and perinatal stress can cause differences in the levels of growth-promoting hormones, particularly insulin-like growth factors (IGF). In combination with the endocrine disruption that occurs following dissociation of the maternal-placental-fetal unit, the premature adaptation to the extrauterine environment leads to early and fast accretion of fat mass in an immature body. In addition, we report on interventional studies that have aimed to compensate for hormonal deficiencies in infants born preterm through IGF therapy, resulting in improved neonatal morbidity and growth. IMPACT: Preterm birth prematurely dissociates the maternal-placental-fetal unit and disrupts the metabolic-endocrine maintenance of the immature fetus with serious consequences for growth, body composition, and neonatal outcomes. The preterm metabolic-endocrine disruption induces symptoms resembling anterior pituitary failure (panhypopituitarism) with low levels of IGF-1, excessive postnatal fat mass accretion, poor longitudinal growth, and failure to thrive. Appropriate gestational age-adapted nutrition alone seems insufficient for the achievement of optimal growth of preterm infants. Preliminary results from interventional studies show promising effects of early IGF-1 supplementation on postnatal development and neonatal outcomes.

Abstract
Background Neonatal pneumonia remains a significant contributor to infant mortality in India and responsible for increased prevalence of infant deaths globally. Objective To identify risk factors associated with neonatal pneumonia and its mortality in India. Study design A systematic review was conducted including both analytic study designs and descriptive study designs, which reported a quantitative analysis of factors associated with all the three types of pneumonia among neonates. The search was conducted from August to December, 2016 on the following databases; CINAHL, EMBASE, Ovid MEDLINE, PubMed, ProQuest, SCOPUS, Web of Science, WHO IMSEAR and IndMED. The search was restricted to Indian setting. Participants The population of interest was neonates. Outcomes The outcome measures included risk factors for incidences and mortality predictors of neonatal pneumonia. These could be related to neonate, maternal and pregnancy, caregiver, family, environment, healthcare system, iatrogenic and others. Results A total of three studies were included. For risk factors, two studies on ventilator-associated pneumonia were included with 194 neonates; whereas for mortality predictors, only one study with 150 neonates diagnosed with pneumonia was included. 11 risk factors were identified from two studies: duration of mechanical ventilation, postnatal age, birth weight, prematurity, sex of the neonate, length of stay in NICU, primary diagnosis, gestational age, number of re-intubation, birth asphyxia, and use of nasogastric tube. Metaanalysis with random-effects model was possible only for prematurity (<37 week) and very low birth weight (<1500 g) and very low birth weight was found to be significant (OR 5.61; 95% CI 1.76, 17.90). A single study was included on predictors of mortality. Mean alveolar arterial oxygen gradient (AaDO2) >250 mm Hg was found to be the single most significant predictor of mortality due to pneumonia in neonates. Conclusion The study found scant evidence from India on risk factors of neonatal pneumonia other than ventilator-associated pneumonia.

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

Abstract
OBJECTIVE Bi-level positive airway pressure (BiPAP) and synchronized intermittent mandatory ventilation (SIMV) can be used to achieve peak inspiratory pressure and positive end-expiratory pressure to avoid alveolar collapse and improve oxygenation in preterm infants during the treatment of respiratory distress syndrome (RDS), and there is an urgent demand for evaluating the effects and prognoses of these two ventilation modes. STUDY DESIGN We conducted a retrospective study on preterm infants (≤32 weeks and <2500 g) from March 2015 to March 2020 with BiPAP (n = 63) and SIMV (n = 63). The primary outcomes were successful treatment and weaning within 72 h, the demand for a second pulmonary surfactant supply and the need for a second respiratory support. The secondary outcome was the incidence of complications. RESULTS There were no significant differences (p > .05) in the primary outcomes or the incidence of complications (pneumonia, apnea, respiratory failure, air leak syndrome, persistence of patent ductus arteriosus, neonatal sepsis, necrotizing enterocolitis, retinopathy of prematurity, and intraventricular hemorrhage). There were significant differences (p < .05) in the incidence of pulmonary hemorrhage, bronchopulmonary dysplasia and IVH (≥grade II). CONCLUSIONS Although both BiPAP and SIMV achieved good early treatment outcomes of RDS in preterm infants, BiPAP support is recommended for reducing the incidence of pulmonary hemorrhage, bronchopulmonary dysplasia and IVH (≥grade II) if infants are tolerant. Attempts should be made to prevent these complications from happening with the use of SIMV support if infants are intolerant.

Oropharyngeal colostrum therapy reduces the incidence of ventilator-associated pneumonia in very low birth weight infants: a systematic review and meta-analysis. Pediatr Res 2021; 89:54-62. [PMID: 32225172 PMCID: PMC7223528 DOI: 10.1038/s41390-020-0854-1] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Revised: 01/16/2020] [Accepted: 02/19/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND Oropharyngeal colostrum (OC) is a novel feeding strategy to prevent complications of prematurity. A meta-analysis was conducted to investigate whether very low birth weight infants (VLBWs) can benefit from OC. METHODS Randomized controlled trials (RCTs) were searched from Embase, PubMed, Web of Science, and Cochrane Central Register of Controlled Trials from the date of inception until May 2019. RCTs were eligible if they used OC therapy on VLBW infants. The primary outcomes included ventilator-associated pneumonia (VAP), necrotizing enterocolitis (NEC), bronchopulmonary dysplasia (BPD), late-onset sepsis, and death. The secondary outcomes included the time of full enteral feeding and the length of stay. RESULTS Eight RCTs involving 682 patients (OC group: 332; non-OC group: 350) were included in the meta-analysis. The results suggested that OC was associated with a significantly reduced incidence of VAP [odds ratio (OR) = 0.39, 95% confidence interval (CI): 0.17-0.88, P = 0.02] and full enteral feeding days (mean difference = -2.66, 95% CI: -4.51 to -0.80, P = 0.005), a potential significance of NEC (OR = 0.51, 95% CI: 0.26-0.99, P = 0.05), a trend toward downregulating mortality (OR = 0.60, 95% CI: 0.34-1.08, P = 0.09) and proven sepsis (OR = 0.64, 95% CI: 0.40-1.01, P = 0.06). CONCLUSIONS OC could significantly reduce the occurrence of VAP, and consequently, its routine use should be considered for VLBWs to prevent infectious diseases. IMPACT OC significantly reduces the occurrence of VAP and NEC in VLBW infants. OC may reduce the incidence of VAP and NEC by increasing IgA levels. Early OC therapy for mechanical ventilation of low-weight infants may prevent the occurrence of VAP.

Abstract
BACKGROUND To evaluate whether soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) can be used as an early predictor of ventilator-associated pneumonia (VAP). METHODS Ventilated neonatal patients admitted into the neonatology department between January 2017 and January 2018 were divided into VAP (n = 30) and non-VAP (n = 30) groups. Serum sTREM, procalcitonin (PCT), C-reactive protein and interleukin-6 levels were measured at 0, 24, 72, and 120 h after initiation of mechanical ventilation (MV). Correlations between blood biomarker concentrations and VAP occurrence were analyzed. Predictive factors for VAP were identified by logistic regression analysis and Hosmer-Lemeshow test, and the predictive value of sTREM-1 and biomarker combinations for VAP was determined by receiver operating characteristic curve analysis. RESULTS The serum sTREM-1 concentration was significantly higher in the VAP group than in the non-VAP group after 72 and 120 h of MV (72 h: 289.5 (179.6-427.0) vs 202.9 (154.8-279.6) pg/ml, P < 0.001; 120 h: 183.9 (119.8-232.1) vs 141.3 (99.8-179.1) pg/ml, P = 0.042). The area under the curve (AUC) for sTREM-1 at 72 h was 0.902 with a sensitivity of 90% and specificity of 77% for the optimal cut-off value of 165.05 pg/ml. Addition of PCT to sTERM-1 at 72 h further improved the predictive value, with this combination having an AUC of 0.971 (95% confidence interval: 0.938-1.000), sensitivity of 0.96, specificity of 0.88, and Youden index of 0.84. CONCLUSION sTREM-1 is a reliable predictor of VAP in neonates, and combined measurement of serum levels of sTREM-1 and PCT after 72 h of MV provided the most accurate prediction of VAP in neonatal patients.

Abstract
A neonate born at 25 + 1/7 weeks developed ventilator-associated pneumonia at 29 + 3/7 weeks post-menstrual age with Escherichia coli that was originally sensitive to gentamicin. After 3 days of treatment with gentamicin, the minimum inhibitory concentration (MIC) changed from less than 1 mg/L to more than 16 mg/L. It appears that suboptimal gentamicin dosing led to the development of gentamicin resistance. As the patient was not improving clinically, the antibiotics were changed once the gentamicin resistance was identified. To minimize resistance and treatment failure, clinicians should consider the patient-specific pharmacokinetic parameters, achieved peak level, and the amount of time the gentamicin level will remain below the MIC of the organism being treated.

Abstract
BACKGROUND AND OBJECTIVE Ventilator-associated pneumonia (VAP) is a common nosocomial infection in critical care settings and might have important long-term consequences in neonates. Our aim is to clarify the short- and long-term respiratory outcomes of neonates affected by VAP. METHODS Prospective, population-based, cohort study with 12 months follow-up based on clinical examinations and diary-based respiratory morbidity score, conducted in an academic tertiary referral neonatal unit with dedicated follow-up program. RESULTS A total of 199 inborn neonates consecutively ventilated for at least 48 hours were eligible for the study. One hundred fifty-one were finally enrolled and classified as "exposed" or "unexposed" to VAP, if they fulfilled (or not) VAP criteria once during their stay. Bronchopulmonary dysplasia (BPD) incidence was significantly higher in exposed (75%) than in unexposed babies (26.8%; relative risk [RR]: 2.8 [1.9-4.0]; Adj RR: 3.5 [1.002-12.7]; P = .049; number needed to harm = 2.07), although the composite BPD/mortality did not differ. Exposed patients showed longer intensive care unit stay (87 [43-116] vs 14 [8-52] days; St.β = 0.24; P < .0001) and duration of ventilation (15 [10-25] vs 5 [4-8] days; St.β = 0.29; P < .0001) than unexposed neonates. Exposed patients also showed less ventilator-free days (11 [5-17.7] vs 22 [14-24] days; St.β = -0.15; P = .05) compared to unexposed. Respiratory infections, use of drugs, rehospitalization for respiratory reasons, home oxygen therapy, their composite outcome, and diary-based clinical respiratory morbidity score were similar between the cohorts. CONCLUSION Neonatal VAP seems associated to higher incidence of BPD, longer ventilation, and intensive care stay but it does not affect long-term respiratory morbidity.

Abstract
Background The aim of this study was to identify the nosocomial infection (NI) risk factors in neonatal Intensive Care Units (NICU). Material/Methods Databases (PubMed, Embase, Cochrane, VANFUN, CNKI, and VTTMS) were searched using index words to find relevant studies published before November 2018. Meta-analyses of relative risk (RR) were performed for the identification of risk factors. Results Data from 22 cohort studies (2270 infants with and 21 605 infants without NI) were included in the meta-analysis. Infant weight of <2500 g (RR: 3.44, 95% CI: 2.31–5.11), gestational age of <37 weeks (RR: 3.85, 95% CI: 1.87–7.92), mechanical ventilation use (RR: 3.16, 95% CI: 2.21–4.50), venipuncture (RR: 3.01, 95% CI: 1.20–7.57), the incidence of asphyxia (RR: 1.68, 95% CI: 1.04–2.71), and feeding intolerance (RR: 2.12, 95% CI: 1.60–2.81) were identified as the risk factors for the incidence of NI. There was no significant publication bias. Conclusions This study shows that <2500 g infant body weight, gestational age of <37 weeks, mechanical ventilation utility, venipuncture, asphyxia incidence, and feeding intolerance are the risk factors for NI nosocomial infection in infants in NICU. Appropriate preventive measures and targeted interventions are needed.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is the second most frequent hospital-acquired infection in neonatal intensive care units (NICUs) and significantly affects neonatal morbidity and mortality. The population most at risk for VAP are extremely preterm infants. PURPOSE The objectives of this quality improvement project were to create and evaluate the effectiveness of a VAP prevention bundle ("ZAP-VAP") in reducing VAP. METHODS The development of the ZAP-VAP bundle and creation of audit tools were documented. A targeted gestational age less than 29 weeks was selected for this study. Electronic medical record review was used to determine the preintervention baseline for patient outcomes. Patient medical record data were analyzed retrospectively to measure patient outcomes preimplementation. VAP rates (number of VAP cases per 1000 ventilator days) were calculated pre- and postintervention. After implementation, data were analyzed prospectively to measure patient outcomes between neonates who developed VAP and those who did not. RESULTS The VAP rate significantly decreased from 8.5 (2010-2011) to 2.5 (P= .0004) postintervention (2016). Median mechanical ventilation days decreased among VAP cases (47 vs 33 days) and slightly increased among non-VAP cases (19 vs 24 days) during the intervention period. Median length of stay decreased for VAP cases (136 vs 100 days) but remained unchanged for non-VAP cases (85 vs 84 days). IMPLICATIONS FOR PRACTICE The intervention was implemented from 2012 to 2016. The protocol was readily accepted by our neonatal intensive care unit (NICU) team through education and practice changes. ZAP-VAP is an effective and straightforward protocol that improved VAP outcomes in our level IIIB NICU. An interdisciplinary team successfully implemented this intervention for mechanically ventilated infants of all gestational ages in our unit and has been a model for these practice changes in other units and other hospitals. IMPLICATIONS FOR RESEARCH Future studies should focus on how to create sustainable interventions to decrease VAP in NICUs and to expand the approaches to other units in our hospital and other hospitals in our city among patients at risk for VAP.

Abstract
Invasive ventilation is often necessary for the treatment of newborn infants with respiratory insufficiency. The neonatal patient has unique physiological characteristics such as small airway caliber, few collateral airways, compliant chest wall, poor airway stability, and low functional residual capacity. Pathologies affecting the newborn's lung are also different from many others observed later in life. Several different ventilation modes and strategies are available to optimize mechanical ventilation and to prevent ventilator-induced lung injury. Important aspects to be considered in ventilating neonates include the use of correct sized endotracheal tube to minimize airway resistance and work of breathing, positioning of the patient, the nursing care, respiratory kinesiotherapy, sedation and analgesia, and infection prevention, namely, the ventilator-associated pneumonia and nosocomial infection, as well as prevention and treatment of complications such as air leaks and pulmonary hemorrhage. Aspects of ventilation in patients under ECMO (extracorporeal membrane oxygenation) and in palliative care are of increasing interest nowadays. Online pulmonary mechanics and function testing as well as capnography are becoming more commonly used. Echocardiography is now a routine in most neonatal units. Near infrared spectroscopy (NIRS) is an attractive tool potentially helping in preventing intraventricular hemorrhage and periventricular leukomalacia. Lung ultrasound is an emerging tool of diagnosis and can be of added value in helping monitoring the ventilated neonate. The aim of this scientific literature review is to address relevant aspects concerning the respiratory care and monitoring of the invasively ventilated newborn in order to help physicians to optimize the efficacy of care.

Neonatal Ventilator Associated Pneumonia: A Quality Improvement Initiative Focusing on Antimicrobial Stewardship. Front Pediatr 2018; 6:262. [PMID: 30320046 PMCID: PMC6165906 DOI: 10.3389/fped.2018.00262] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Accepted: 09/03/2018] [Indexed: 12/24/2022] Open
Abstract
Background and Aims: Neonatal ventilator associated pneumonia (VAP) is a common nosocomial infection and a frequent reason for empirical antibiotic therapy in NICUs. Nonetheless, there is no international consensus regarding diagnostic criteria and management. In a first step, we analyzed the used diagnostic criteria, risk factors and therapeutic management of neonatal VAP by a literature review. In a second step, we aimed to compare suspected vs. confirmed neonatal VAP episodes in our unit according to different published criteria and to analyze interrater-reliability of chest x-rays. Additionally, we aimed to evaluate the development of VAP incidence and antibiotic use after implementation of multifaceted quality improvement changes regarding antimicrobial stewardship and infection control (VAP-prevention-bundle, early-extubation policy, antimicrobial stewardship rounds). Methods: Neonates until 44 weeks of gestation with suspected VAP, hospitalized at our level-III NICU in Lucerne from September 2014 to December 2017 were enrolled. VAP episodes were analyzed according to 4 diagnostic frameworks. Agreement regarding chest x-ray interpretation done by 10 senior physicians was assessed. Annual incidence of suspected and confirmed neonatal VAP episodes and antibiotic days were calculated and compared for the years 2015, 2016, and 2017. Results: 17 studies were identified in our literature review. Overall, CDC-guidelines or similar criteria, requesting radiographic changes as main criteria, are mostly used. Comparison of suspected vs. confirmed neonatal VAP episodes showed a great variance (20.4 vs. 4.5/1,000 ventilator-days). The interrater-reliability of x-ray interpretation was poor (intra-class correlation 0.25). Implemented changes resulted in a gradual decline in annual VAP incidence and antibiotic days from 2015 compared with 2017 (28.8 vs. 7.4 suspected episodes/1,000 ventilator-days, 5.5 vs. 0 confirmed episodes/1,000 ventilator-days and 211 vs. 34.7 antibiotic days/1,000 ventilation-days, respectively). Conclusion: The incidence of suspected VAP and concomitant antibiotic use is much higher than for confirmed VAP, therefore inclusion of suspected episodes should be considered for accurate evaluation. There is a high diagnostic inconsistency and a low reliability of interpretation of chest x-rays regarding VAP. Implementation of combined antimicrobial stewardship and infection control measures may lead to an effective decrease in VAP incidence and antibiotic use.
