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.

Abstract
PURPOSE Ventilator-associated pneumonia (VAP) is a common healthcare-associated infection in pediatric intensive care unit (PICU), increasing mortality, antibiotics use and duration of ventilation and hospitalization. VAP diagnosis is based on clinical and chest X-ray (CXR) signs defined by the 2018 Center for Disease Control (gold standard). However, CXR induces repetitive patients' irradiation and technical limitations. This study aimed to investigate if lung ultrasound (LUS) can substitute CXR in the VAP diagnosis. METHODS A monocentric and prospective study was conducted in a French tertiary care hospital. Patients under 18-year-old admitted to PICU between November 2018 and July 2020 with invasive mechanical ventilation for more than 48 h were included. The studied LUS signs were consolidations, dynamic air bronchogram, subpleural consolidations (SPC), B-lines, and pleural effusion. The diagnostic values of each sign associated with clinical signs (cCDC) were compared to the gold standard approach. LUS, chest X-ray, and clinical score were performed daily. RESULTS Fifty-seven patients were included. The median age was 8 [3-34] months. Nineteen (33%) children developed a VAP. In patients with VAP, B-Lines, and consolidations were highly frequent (100 and 68.8%) and, associated with cCDC, were highly sensitive (100 [79-100] % and 88 [62-98] %, respectively) and specific (95.5 [92-98] % and 98 [95-99] %, respectively). Other studied signs, including SPC, showed high specificity (>97%) but low sensibility (<50%). CONCLUSION LUS seems to be a powerful tool for VAP diagnosis in children with a clinical suspicion, efficiently substituting CXR, and limiting children's exposure to ionizing radiations.

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
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
OBJECTIVE Ventilator-associated pneumonia (VAP) is one of the most common healthcare-associated infections in pediatric intensive care units (PICUs), but its definite diagnosis remains controversial. The CDC Ventilator-Associated Event (VAE) module (validated in adults) constitutes a new approach for VAP surveillance. DESIGN We described epidemiological characteristics of PICU VAE cases, investigated possible risk factors, and evaluated 3 different sets of diagnostic VAE criteria. SETTING This study was conducted in a PICU in a tertiary-care general hospital in northern Greece during 2017-2019. PATIENTS The study included patients aged 35 days-16 years who received mechanical ventilation. METHODS From medical records, we retrieved epidemiological data, clinical data, and laboratory characteristics as well as ventilator settings for our analysis. We assessed "oxygen deterioration" for the tier 1 CDC VAE module using 3 sets of diagnostic criteria: (1) CDC adult VAE criteria [increase of daily minimum fraction of inspired oxygen (FiO2) ≥ 0.2 or positive end expiratory pressure (PEEP) ≥ 3 cmH2O for 2 days], (2) the US pediatric VAE criteria [increase of FiO2 ≥ 0.25 or mean airway pressure (MAP) ≥ 4 cmH2O for 2 days], and (3) the European pediatric VAE criteria (increase of FiO2 ≥ 0.2 or PEEP ≥ 2 cmH2O for 1 day or increase of FiO2 ≥ 0.15 and PEEP ≥ 1 cm H2O for 1 day). RESULTS Among 326 children admitted to the PICU, 301 received mechanical ventilation. The incidence rate according to the CDC adult VAE criteria was 4.7 per 1,000 ventilator days. For the US pediatric VAE criteria the incidence rate was 6 per 1,000 ventilator days. For the European pediatric VAE criteria the incidence rate was 9.7 per 1,000 ventilator days. These results revealed statistically significant correlation of all 3 algorithms with adverse outcomes, including mortality. CONCLUSIONS All VAE algorithms were associated with higher mortality rates. Our findings highlight the need for a unified pediatric VAE definition to improve preventive strategies.

Abstract
Ventilator-associated pneumonia (VAP), one of the most common healthcare-associated infections in intensive care settings, is associated with significant morbidity and mortality. VAP is diagnosed in >10% of patients on mechanical ventilation, incidence rising with number of ventilator days. In recent decades, the pathophysiology of VAP, VAP risk factors and treatment have been extensively studied. In critically ill pediatric patients, mechanical issues such as insufficient tightness of the ventilator circuit (mainly due to historically based preference of uncuffed tubes) and excessive humidity in the circuit are both significant risk factors of VAP development. Protocol-based approaches to critically ill patients on mechanical ventilation, closed suctioning, upper body position, enteral feeding and selective gastric acid suppression medication have a beneficial effect on VAP incidence. In recent decades, cuffed tubes applied to the whole spectrum of critically ill pediatric patients (except neonates <2700 g of weight), together with cuff-oriented nursing care including proper cuff-pressure (<20 cm H2O) management and the use of specialized tracheal tubes with subglottic suction ports combined with close infraglottic tracheal suctioning, have been implemented. The aim of this review was to summarize the current evidence-based knowledge about the pathophysiology, risk factors, diagnosis, treatment and prevention of VAP in clinically oriented settings.

Abstract
The concept of improving the quality and safety of healthcare is well known. However, a follow-up question is often asked about whether these improvements are cost-effective. The prevalence of nosocomial infections (NIs) in the neonatal intensive care unit (NICU) is approximately 30% in developing countries. Ventilator-associated pneumonia (VAP) is the second most common NI in the NICU. Reducing the incidence of NIs can offer patients better and safer treatment and at the same time can provide cost savings for hospitals and payers. The aim of the study is to assess the direct costs of VAP in the NICU. This is a prospective study, conducted between January 2017 and June 2018 in the NICU of University Hospital “St. George” Plovdiv, Bulgaria. During this period, 107 neonates were ventilated for more than 48 h and included in the study. The costs for the hospital stay are based on the records from the Accounting Database of the setting. The differences directly attributable to VAP are presented both as an absolute value and percentage, based on the difference between the values of the analyzed variables. There are no statistically significant differences between patients with and without VAP in terms of age, sex, APGAR score, time of admission after birth and survival. We confirmed differences between the median birth weight (U = 924, p = 0.045) and average gestational age (t = 2.14, p = 0.035) of the patients in the two study groups. The median length of stay (patient-days) for patients with VAP is 32 days, compared to 18 days for non-VAP patients (U = 1752, p < 0.001). The attributive hospital stay due to VAP is 14 days. The median hospital costs for patients with VAP are estimated at €3675.77, compared to the lower expenses of €2327.78 for non-VAP patients (U = 1791.5, p < 0.001). The median cost for antibiotic therapy for patients with VAP is €432.79, compared to €351.61 for patients without VAP (U = 1556, p = 0.024). Our analysis confirms the results of other studies that the increased length of hospital stays due to VAP results in an increase in hospital costs. VAP is particularly associated with prematurity, low birth weight and prolonged mechanical ventilation.

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.

The Paediatric AirWay Suction (PAWS) appropriateness guide for endotracheal suction interventions. Aust Crit Care 2021; 35:651-660. [PMID: 34953635 DOI: 10.1016/j.aucc.2021.10.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2021] [Revised: 10/10/2021] [Accepted: 10/17/2021] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND/OBJECTIVE Endotracheal suction is an invasive and potentially harmful technique used for airway clearance in mechanically ventilated children. Choice of suction intervention remains a complex and variable process. We sought to develop appropriate use criteria for endotracheal suction interventions used in paediatric populations. METHODS The RAND Corporation and University of California, Los Angeles Appropriateness Method was used to develop the Paediatric AirWay Suction appropriateness guide. This included defining key terms, synthesising current evidence, engaging an expert multidisciplinary panel, case scenario development, and two rounds of appropriateness ratings (weighing harm with benefit). Indications (clinical scenarios) were developed from common applications or anticipated use, current practice guidelines, clinical trial results, and expert consultation. RESULTS Overall, 148 (19%) scenarios were rated as appropriate (benefit outweighs harm), 542 (67%) as uncertain, and 94 (11%) as inappropriate (harm outweighs benefit). Disagreement occurred in 24 (3%) clinical scenarios, namely presuction and postsuction bagging across populations and age groups. In general, the use of closed suction was rated as appropriate, particularly in the subspecialty population 'patients with highly infectious respiratory disease'. Routine application of 0.9% saline for nonrespiratory indications was more likely to be inappropriate/uncertain than appropriate. Panellists preferred clinically indicated suction versus routine suction in most circumstances. CONCLUSION Appropriate use criteria for endotracheal suction in the paediatric intensive care have the potential to impact clinical decision-making, reduce practice variability, and improve patient outcomes. Furthermore, recognition of uncertain clinical scenarios facilitates identification of areas that would benefit from future research.

Abstract
BACKGROUND Hospital-acquired pneumonia is one of the most common hospital-acquired infections in children worldwide. Most of our understanding of hospital-acquired pneumonia in children is derived from adult studies. To our knowledge, no systematic review with meta-analysis has assessed the benefits and harms of different antibiotic regimens in neonates and children with hospital-acquired pneumonia. OBJECTIVES To assess the beneficial and harmful effects of different antibiotic regimens for hospital-acquired pneumonia in neonates and children. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, three other databases, and two trial registers to February 2021, together with reference checking, citation searching, and contact with study authors to identify additional studies. SELECTION CRITERIA We included randomised clinical trials comparing one antibiotic regimen with any other antibiotic regimen for hospital-acquired pneumonia in neonates and children. DATA COLLECTION AND ANALYSIS Three review authors independently assessed studies for inclusion, extracted data, and assessed risk of bias. We assessed the certainty of the evidence using the GRADE approach. Our primary outcomes were all-cause mortality and serious adverse events; our secondary outcomes were health-related quality of life, pneumonia-related mortality, non-serious adverse events, and treatment failure. Our primary time point of interest was at maximum follow-up. MAIN RESULTS We included four randomised clinical trials (84 participants). We assessed all trials as having high risk of bias. We did not conduct any meta-analyses, as the included trials did not compare similar antibiotic regimens. Each of the four trials assessed a different comparison, as follows: cefepime versus ceftazidime; linezolid versus vancomycin; meropenem versus cefotaxime; and ceftobiprole versus cephalosporin. Only one trial reported our primary outcomes of all-cause mortality and serious adverse events. Three trials reported our secondary outcome of treatment failure. Two trials primarily included community-acquired pneumonia and hospitalised children with bacterial infections, hence the children with hospital-acquired pneumonia constituted subgroups of the total sample sizes. Where outcomes were reported, the certainty of the evidence was very low for each of the comparisons. We are unable to draw meaningful conclusions from the numerical results. None of the included trials assessed health-related quality of life, pneumonia-related mortality, or non-serious adverse events. AUTHORS' CONCLUSIONS The relative beneficial and harmful effects of different antibiotic regimens remain unclear due to the very low certainty of the available evidence. The current evidence is insufficient to support any antibiotic regimen being superior to another.

Abstract
This paper is aimed at addressing all the critical aspects linked to the implementation of intensive care ventilators in a pediatric setting, highlighting the most relevant technical features and describing the methodology to conduct health technology assessment (HTA) for supporting the decision-making process. Four ventilator models were included in the assessment process. A decision-making support tool (DoHTA method) was applied. Twenty-eight Key Performance Indicators (KPIs) were identified, defining the safety, clinical effectiveness, organizational, technical, and economic aspects. The Performance scores of each ventilator have been measured with respect to KPIs integrated with the total cost of ownership analysis, leading to a final rank of the four possible technological solutions. The final technologies' performance scores reflected a deliver valued, contextualized, and shared outputs, detecting the most performant technological solution for the specific hospital context. HTA results had informed and supported the pediatric hospital decision-making process. This study, critically identifying the pros and cons of innovative features of ventilators and the evaluation criteria and aspects to be taken into account during HTA, can be considered as a valuable proof of evidence as well as a reliable and transferable method for conducting decision-making processes in a hospital context.

Abstract
Background A few studies are available from Africa on the use of mechanical ventilation (MV) in the pediatric intensive care unit (PICU). Knowledge of the outcome of patients on MV is critical for better use of resources. We aimed to assess the characteristics and outcomes of mechanically ventilated pediatric patients in Tikur Anbessa Specialized Referral Hospital, Addis Ababa, Ethiopia. Methods A cross-sectional study was done from September 2016 to February 2018. Data were reviewed from the patients' medical records. SPSS version 21 software was used for data entry and analysis. Results There were 536 patients admitted to PICU; out of these, 202 (41.2%) were on MV. Sixty-three-point six percent of the participants were males and 130 (59.1%) died. The most common indications for the initiation of MV were respiratory problems 46 (20.9%) and 30.59/1000 ventilator days developed complications. Ventilator-associated pneumonia accounted for 18.6% of the complications with 20.9/1000 ventilator days. Survival of medical cases was better than the surgical cases (including trauma); [AOR= 0.13, 95% CI (0.04–0.41)] and those who have MV for more than 3 days are 79% more likely to die (p=0.003). Those who have multi-organ dysfunction syndrome (MODS) [AOR= 0.181, 95% CI (0.08, 0.412)] and high PIM II severity score [AOR= 35, 95% CI (1.7,11)] had higher mortality rate. Conclusions higher PIM II score, MODS, length of stay, and being a surgical patient increased the risk of mortality. Early resuscitation and thorough follow up of these ventilated patients are necessary.

[PMID: 33925064 PMCID: PMC8124660 DOI: 10.3390/ijerph18094703] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 04/24/2021] [Accepted: 04/26/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Hospital-Acquired Infections (HAIs) represent the most frequent adverse event associated with healthcare delivery and result in prolonged hospital stays and deaths worldwide. AIM To analyze the spatial patterns of HAI incidence from 2014 to 2017 in Portugal. METHODS Data from the Portuguese Discharge Hospital Register were used. We selected episodes of patients with no infection on admission and with any of the following HAI diagnoses: catheter-related bloodstream infections, intestinal infections by Clostridium difficile, nosocomial pneumonia, surgical site infections, and urinary tract infections. We calculated age-standardized hospitalization rates (ASHR) by place of patient residence. We used empirical Bayes estimators to smooth the ASHR. The Moran Index and Local Index of Spatial Autocorrelation (LISA) were calculated to identify spatial clusters. RESULTS A total of 318,218 HAIs were registered, with men accounting for 49.8% cases. The median length of stay (LOS) was 9.0 days, and 15.7% of patients died during the hospitalization. The peak of HAIs (n = 81,690) occurred in 2015, representing 9.4% of the total hospital admissions. Substantial spatial inequalities were observed, with the center region presenting three times the ASHR of the north. A slight decrease in ASHR was observed after 2015. Pneumonia was the most frequent HAI in all age groups. CONCLUSION The incidence of HAI is not randomly distributed in the space; clusters of high risk in the central region were seen over the entire study period. These findings may be useful to support healthcare policymakers and to promote a revision of infection control policies, providing insights for improved implementation.

Abstract
BACKGROUND Surveillance is essential to all aspects of management of healthcare-associated infections (HAIs) in critically ill children, where data are limited. We conducted an active surveillance study to elucidate epidemiology, resistance, antimicrobial treatment practices and outcomes of pediatric intensive care unit-acquired HAIs in a southern European country. METHODS Four Greek pediatric intensive care unit encounters (153 patients, 2183 patient-days) during a 6-month period participated using the European Centre for Disease Prevention and Control HAI-net ICU (v2.2) protocol. Bloodstream infections and device-associated HAIs were recorded. Clinical severity, isolated pathogens, antimicrobial resistance and antibiotic prescriptions were collected on a daily basis. Mortality and excess length of stay due to HAI were also assessed. RESULTS Overall rate of HAIs was 18.3 per 1000 patient-days. Aggregate rates for device-associated HAI were: catheter-related bloodstream infection 2.32, intubation-associated pneumonia 10.5, and catheter-associated urinary tract infection 4.6 per 1000 device-days. Children with HAI (n = 28, 18.3%) had higher severity of illness (Pediatric Risk Mortality Score 7.5 vs. 4, P < 0.001), longer hospitalization (23 vs. 6 days, P < 0.001), but not higher mortality, compared with those without. Most frequent recovered pathogens were Klebsiella pneumoniae (40%), Pseudomonas aeruginosa (22.5%), Acinetobacter baumannii (12.5%), with respective carbapenem resistance 50%, 44% and 80%, and Staphylococcus aureus (12.5%). Total antibiotic use was 2142 days of treatment per 1000 patient-days. CONCLUSIONS Our study, based on the updated ECDC HAI-net ICU (v2.2) protocol, effectively addresses the significant burden of HAIs in critically ill children in Greece. Using a well-standardized system facilitates inter- and intra-countries reliable recordings and comparative assessments of infection control programs.

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
Background: Among hospital-acquired infections (HAIs) in children, ventilator-associated pneumonia (VAP) is the most common after blood stream infection (BSI). VAP can prolong length of ventilation and hospitalization, increase mortality rate, and directly change a patient’s outcome in Pediatric Intensive Care Units (PICU). Objectives: The research on VAP in children is limited, especially in Iran; therefore, the identification of VAP incidence and mortality rate will be important for both clinical and epidemiological implications. Materials and Methods: Mechanically ventilated pediatric patients were assessed for development of VAP during hospital course on the basis of clinical, laboratory and imaging criteria. We matched VAP group with control group for assessment of VAP related mortality in the critically ill ventilated children. Results: VAP developed in 22.9% of critically ill children undergoing mechanical ventilation. Early VAP and late VAP were found in 19.3% and 8.4% of VAP cases, respectively. Among the known VAP risk factors that were investigated, immunodeficiency was significantly greater in the VAP group (p = 0.014). No significant differences were found between the two groups regarding use of corticosteroids, antibiotics, PH (potential of hydrogen) modifying agents (such as ranitidine or pantoprazole), presence of nasogastric tube and total or partial parenteral nutrition administration. A substantial number of patients in the VAP group had more than four risk factors for development of VAP, compared to those without VAP (p = 0.087). Mortality rate was not statistically different between the VAP and control groups (p = 0.477). Conclusion: VAP is still one of the major causes of mortality in PICUs. It is found that altered immune status is a significant risk factor for acquiring VAP. Also, occurrence of VAP was high in the first week after admission in PICU.

Abstract
Abstract
Low birth weight newborns (≤1500 grams) are at a high risk of acquiring hospital infections due to the immaturity of the immune system, lack of efficient structural barriers, and an incomplete development of endogenous microbial flora.
The aim of this study was to reveal the potential risk factors for hospital-acquired pneumonia in low birth weight newborns.
This study was a prospective cohort design with a nested case-control study and was conducted between January 1st, 2012 and June 30th, 2015 at the Neonatology Department, Clinical Centre Kragujevac, Serbia. There were 1140 newborns hospitalized at the Neonatology Department for longer than 48 hours during the study period, and 169 of them (14.82%) weighed less than 1500 grams at birth. In total, 73 (43.19%) newborns with low birth weights developed HIs. The most prevalent HI was hospital pneumonia (n=64, 87.67%).
Although univariate analyses identified many risk factors with a significant influence on the occurrence of hospital pneumonia, multivariate analysis identified only the following two independent risk factors for hospital pneumonia in newborns with birth weights below 1500 grams: mechanical ventilation (p=0.003, OR=68.893, 95% CI=4.285-1107.699) and longer hospitalization (p=0.003, OR=1.052, 95% CI=1.017-1.088). Almost all of the pathogens isolated from the patients with pneumonia were gram-negative bacteria (98.50%). More than half of all of the isolates were Acinetobacter spp (37.50%) and Enterobacter spp (18.75%).
Our study showed that mechanical ventilation and prolonged hospitalization were significant risk factors for the development of hospital pneumonia in newborns with birth weights below 1500 grams.
