Project description:Administration of oropharyngeal colostrum (OPC) is safe, feasible, and potentially beneficial in preterm infants. We aimed to assess the effects of OPC in preterm infants. A systematic review of randomized controlled trials (RCTs) and non-RCTs of OPC administration in preterm infants was conducted. We searched MEDLINE via PubMed and Ovid, EMBASE, the Cochrane Central Register of Controlled Trials, Emcare databases, abstracts of Pediatric Academic Societies meetings, and gray literature in April 2018. Six RCTs (n = 269) and 4 non-RCTs (n = 737) were included. One RCT (n = 40) focused on enteral bovine colostrum and hence was excluded from our review. Five of the 6 RCTs had unclear risk of bias in many domains of assessment. Meta-analysis (random effects model) of RCT data showed no significant difference in ≥stage 2 necrotizing enterocolitis (RR: 0.83; 95% CI: 0.39, 1.75; P = 0.62), late-onset sepsis (RR: 0.78; 95% CI: 0.50, 1.22; P = 0.28), all-cause mortality (RR: 0.74; 95% CI: 0.27, 2.06; P = 0.56); duration of hospital stay (mean difference [MD]: -1.65 d; 95% CI: -10.09, 6.80; P = 0.70), and time to full feeds (MD: -2.86 d; 95% CI: -6.49, 0.77; P = 0.12). Meta-analysis of data from non-RCTs also showed no benefit for any of these outcomes. OPC increased secretory IgA and lactoferrin concentrations (4 RCTs), and had only a transient effect on the oral microbiome (1 RCT). There were no adverse effects (e.g., aspiration) of OPC. The overall quality of evidence (Grades of Recommendation, Assessment, Development, and Evaluation analysis) was very low. Adequately powered RCTs are needed to confirm the nutritional and immunomodulatory benefits of OPC in preterm infants.

Project description:BACKGROUND: Preterm infants requiring assisted ventilation are at significant risk of both pulmonary and cerebral injury. Inhaled Nitric Oxide, an effective therapy for pulmonary hypertension and hypoxic respiratory failure in the full term infant, has also been studied in preterm infants. The most recent Cochrane review of preterm infants includes 11 studies and 3,370 participants. The results show a statistically significant reduction in the combined outcome of death or chronic lung disease (CLD) in two studies with routine use of iNO in intubated preterm infants. However, uncertainty remains as a larger study (Kinsella 2006) showed no significant benefit for iNO for this combined outcome. Also, trials that included very ill infants do not demonstrate significant benefit. One trial of iNO treatment at a later postnatal age reported a decrease in the incidence of CLD. The aim of this individual patient meta-analysis is to confirm or refute these potentially conflicting results and to determine the extent to which patient or treatment characteristics may explain the results and/or may predict benefit from inhaled Nitric Oxide in preterm infants. METHODS/DESIGN: The Meta-Analysis of Preterm Patients on inhaled Nitric Oxide (MAPPiNO) Collaboration will perform an individual patient data meta-analysis to answer these important clinical questions. Studies will be included if preterm infants receiving assisted ventilation are randomized to receive inhaled Nitric Oxide or to a control group. The individual patient data provided by the Collaborators will be analyzed on an intention-to-treat basis where possible. Binary outcomes will be analyzed using log-binomial regression models and continuous outcomes will be analyzed using linear fixed effects models. Adjustments for trial differences will be made by including the trial variable in the model specification. DISCUSSION: Thirteen (13) trials, with a total of 3567 infants are eligible for inclusion in the MAPPiNO systematic review. To date 11 trials (n = 3298, 92% of available patients) have agreed to participate. Funding was successfully granted from Ikaria Inc as an unrestricted grant. A collaborative group was formed in 2006 with data collection commencing in 2007. It is anticipated that data analysis will commence in late 2009 with results being publicly available in 2010.

Project description:Objectives: Through a systematic review and meta-analysis of the literature we aimed to compare the levels of BDNF, NGF, NT-3, NT-4, and GDNF between human term and preterm infants, and investigate factors implicated in the variability of effect size estimates. Methods: The analysis was performed in three online databases, MEDLINE Complete, PsycINFO, and CINAHL. A random effects model was used to calculate the standardized mean difference (SMD) of neurotrophic factor levels in preterm infants vs. term within a 95% confidence interval (CI). To explore sources of heterogeneity meta-regression models were implemented. Results: Sixteen studies were included in this meta-analysis. A combined sample of 1,379 preterm and 1,286 term newborns were evaluated. We identified significant lower BDNF (SMD = -0.32; 95% CI: -0.59, -0.06; p = 0.014) and NT-3 (SMD = -0.31; 95% CI: -0.52, -0.09; p = 0.004) levels in preterm compared to term infants. No significant difference was observed in NGF and NT-4 levels between groups. Given that only two effect sizes were generated for GDNF levels, no meta-analytical model was performed. Meta-regression models revealed sample type (placental tissue, cerebrospinal fluid, peripheral blood, and umbilical cord blood) as a significant moderator of heterogeneity for BDNF meta-analysis. No significant associations were found for gestational week, birth weight, and clinical comorbidity of newborns with effect sizes. Conclusions: Our findings indicated that lower BDNF and NT-3 levels may be associated with preterm birth. Future studies with larger samples sizes should investigate neurodevelopmental manifestations resulting from neurotrophic factor dysregulation among preterm infants.

Project description:IntroductionThis overview aims to systematically review evidence regarding effects of interventions undertaken in neonatal units to increase breastfeeding in preterm infants.MethodsWe followed Cochrane methodology. Systematic reviews published to October 31, 2022, reporting meta-analysis of effects from original studies on breastfeeding rates in preterm infants of neonatal unit interventions designed to increase breastfeeding were included.ResultsAvoidance of bottles during breastfeed establishment (comparator breastfeeds with bottle-feeds) demonstrated clear evidence of benefit for any breastfeeding at discharge and exclusive breastfeeding 3 months post-discharge, and possible evidence of benefit for exclusive breastfeeding at discharge, and any breastfeeding post-discharge. Kangaroo mother care (KMC) (comparator usual care) demonstrated clear evidence of benefit for any and exclusive breastfeeding at discharge and possible benefit for any breastfeeding post-discharge. Quality improvement (QI) bundle(s) to enable breastfeeds (comparator conventional care) showed possible evidence of benefit for any breastfeeding at discharge. Cup feeding (comparator other supplemental enteral feeding forms) demonstrated possible evidence of benefit for exclusive breastfeeding at discharge and any breastfeeding 3 months after. Early onset KMC (commenced <24 h post-birth), oral stimulation, and oropharyngeal colostrum administration, showed no evidence of benefit. No meta-analyses reported pooled effects for gestational age or birthweight subgroups.ConclusionThere is ample evidence to support investment in KMC, avoidance of bottles during breastfeed establishment, cup feeding, and QI bundles targeted at better supporting breastfeeding in neonatal units to increase prevalence of breastfeeding in preterm infants and promote equal access to breastmilk. Stratifying effects by relevant subgroups is a research priority.

Project description:The purpose of this study is to assess whether pacifier use is associated with breastfeeding success in term and preterm newborns and whether it influences hospitalization time in preterm newborns. Four databases were searched for randomized controlled trials (RCTs), and a systematic review and meta-analysis were conducted. The risk of bias and evidence quality, according to the GRADE methodology, were analyzed. Risk ratios with 95% confidence intervals (CI) for dichotomous outcomes and mean difference (MD) for continuous outcomes were used. The random effect model was used if heterogeneity was high (I2 over 40%). We screened 772 abstracts, assessed 44 full texts, and included 10 studies, of which 5 focused on term and 5 on preterm newborns. There were a few concerns about the risk of bias in 9 of the 10 studies. Breastfeeding rates were analyzed at 2, 3, 4, and 6 months, and the success rates were similar between the restricted and free pacifier use groups (evidence quality was moderate to high). In preterm neonates, the use of a pacifier shortened the duration of hospitalization by 7 days (MD 7.23, CI 3.98-10.48) and the time from gavage to total oral feeding by more than 3 days (MD 3.21 days, CI 1.19-5.24) (evidence quality was ranked as moderate). Conclusions: Based on our meta-analysis, pacifier use should not be restricted in term newborns, as it is not associated with lower breastfeeding success rates. Furthermore, introducing pacifiers to preterm newborns should be considered, as it seems to shorten the time to discharge as well as the transition time from gavage to total oral feeding. What is Known: • Observational studies show that infants who use a pacifier are weaned from breastfeeding earlier. • Previous randomized studies have not presented such results, and there have been no differences in the successful breastfeeding rates regardless of the use of pacifier. What is New: • Term and preterm newborns do not have worse breastfeeding outcomes if a pacifier is introduced to them, and additionally preterm newborns have shorter hospitalization times. • The decision to offer a pacifier should depend on the caregivers instead of hospital policy or staff recommendation, as there is no evidence to support the prohibition or restriction.

Project description:Background and objectivesContinuous glucose monitoring (CGM) could be a valuable instrument for measurement of glucose concentration in preterm neonate. We undertook a systematic review and meta-analysis to compare the diagnostic accuracy of CGM devices to intermittent blood glucose evaluation methods for the detection of hypoglycaemic or hypoglycaemic events in preterm infants.Data sourcesA structured electronic database search was performed for studies that assessed the accuracy of CGM against any intermittent blood glucose testing methods in detecting episodes of altered glycaemia in preterm infants. No restrictions were used. Three review authors screened records and included studies.Data extractionRisk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. From individual patient data (IPD), sensitivity and specificity were determined using predefined thresholds. The mean absolute relative difference (MARD) of the studied CGM devices was assessed and if those satisfied the accuracy requirements (EN ISO 15197). IPD datasets were meta-analysed using a logistic mixed-effects model. A bivariate model was used to estimate the summary receiver operating characteristic curve (ROC) curve and extract the area under the curve (AUC). The overall level of certainty of the evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation.ResultsAmong 4481 records, 11 were included. IPD datasets were obtained for five studies. Only two of the studies showed an MARD lower than 10%, with none of the five CGM devices studied satisfying the European Union (EU) ISO 15197 requirements. Pooled sensitivity and specificity of CGM devices for hypoglycaemia were 0.39 and 0.99, whereas for hyperglycaemia were 0.87 and 0.99, respectively. The AUC was 0.70 and 0.86, respectively. The certainty of the evidence was considered as low to moderate. Limitations primarily related to the lack of representative population, reference standard and CGM device.ConclusionsCGM devices demonstrated low sensitivity for detecting hypoglycaemia in preterm infants, however, provided high accuracy for detection of hyperglycaemia.Prospero registration numberCRD42020152248.

Project description:ObjectivePrevious some systematic reviews reported that probiotics may benefit the prevention of NEC in preterm infants. But dissimilar bacterial strains and taxa used in included studies possibly result in bias. There is not a rounded systematic review which has estimated the benefit and safety of Enterococcus faecium to prevent NEC in preterm infants to date before we conducted.MethodsThis systematic review of randomized controlled trials and retrospective studies analyzing the benefit of Enterococcus faecium to prevent NEC in preterm infants was performed using PubMed, Web of Science, Cochrane Library, EMBASE, Wanfang data and China National Knowledge Infrastructure databases from inception to April 14, 2023. The search terms were "preterm" AND "necrotizing enterocolitis" AND "Enterococcus faecium OR probiotics." Studies reporting NEC involving preterm infants who were given Enterococcus faecium were included in this systematic review. A sensitivity analysis was conducted to assess the stability of results. A funnel plot was generated to identify publication bias. Two authors appraised studies quality and extracted data independently. This work has been reported according with preferred reporting items for systematic reviews and meta-analyses and assessing the methodological quality of systematic reviews. Statistical analysis was conducted using Review Manager 5.3 software. Risk ratio (RR) with 95% confidence intervals (CI) was calculated and analyzed.ResultsSeven studies (N = 1487 participants) were included in this systematic review, and 6 randomized, controlled trials (N = 1237 participants) were included in the meta-analysis. Comparing with the control groups, the Enterococcus faecium groups had a significant decline in the incidence of NEC Bell stage II or higher (RR: 0.3138, 95% CI: 0.1983-0.4965; P < .00001; 6 studies, n = 1237) and infection (RR: 0.4818, 95% CI: 0.2950-0.7869; P = .004; 3 studies, n = 710).ConclusionsEnterococcus faecium is effective and safe in preventing NEC (Bell stage II or higher) in preterm infants. But all studies included came from China. The dosages and durations of taking Enterococcus faecium were various.

Project description:ImportanceMost preterm infants require respiratory support to establish lung aeration after birth. Intermittent positive pressure ventilation and continuous positive airway pressure are standard therapies. An initial sustained inflation (inflation time >5 seconds) is a widely practiced alternative strategy.ObjectiveTo conduct a systematic review and meta-analysis of sustained inflation vs intermittent positive pressure ventilation and continuous positive airway pressure for the prevention of hospital mortality and morbidity for preterm infants.Data sourcesMEDLINE (through PubMed), Embase, the Cumulative Index of Nursing and Allied Health Literature, and the Cochrane Central Register of Controlled Trials were searched through June 24, 2019.Study selectionRandomized clinical trials of preterm infants born at less than 37 weeks' gestation that compared sustained inflation (inflation time >5 seconds) vs standard resuscitation with either intermittent positive pressure ventilation or continuous positive airway pressure were included. Studies including other cointerventions were excluded.Data extraction and synthesisTwo reviewers assessed the risk of bias of included studies. Meta-analysis of pooled outcome data used a fixed-effects model specific to rarer events. Subgroups were based on gestational age and study design (rescue vs prophylactic sustained inflation).Main outcomes and measuresDeath before hospital discharge.ResultsNine studies recruiting 1406 infants met inclusion criteria. Death before hospital discharge occurred in 85 of 736 infants (11.5%) treated with sustained inflation and 62 of 670 infants (9.3%) who received standard therapy for a risk difference of 3.6% (95% CI, -0.7% to 7.9%). Although analysis of the primary outcome identified important heterogeneity based on gestational age subgroups, the 95% CI for the risk difference included 0 for each individual gestational age subgroup. There was no difference in the primary outcome between subgroups based on study design. Sustained inflation was associated with increased risk of death in the first 2 days after birth (risk difference, 3.1%; 95% CI, 0.9%-5.3%). No differences in the risk of other secondary outcomes were identified. The quality-of-evidence assessment was low owing to risk of bias and imprecision.Conclusions and relevanceThere was no difference in the risk of the primary outcome of death before hospital discharge, and there was no evidence of efficacy for sustained inflation to prevent secondary outcomes. These findings do not support the routine use of sustained inflation for preterm infants after birth.

Project description:ObjectiveSurfactant administration via a thin catheter (STC) is an alternative to surfactant administration post endotracheal intubation in preterm infants with respiratory distress syndrome (RDS); however, the benefits particularly in infants <29 weeks' gestation and the neurodevelopmental outcomes remain unclear. Thus, our objective was to systematically review and meta-analyze the efficacy and safety of STC compared to intubation for surfactant or nasal continuous positive airway pressure (nCPAP) in preterm infants with RDS.MethodsMedical databases were searched until December 2022 for randomized controlled trials (RCTs) assessing STC compared to controls that included intubation for surfactant or nCPAP in preterm infants with RDS. The primary outcome was bronchopulmonary dysplasia (BPD) at 36 weeks gestation in survivors. Subgroup analysis was conducted comparing STC to controls in infants < 29 weeks' gestation. The Cochrane risk of bias (ROB) tool was used and certainty of evidence (CoE) was rated according to GRADE.ResultsTwenty-six RCTs of 3349 preterm infants, in which half of the studies had low risk of bias, were included. STC decreased the risk of BPD in survivors compared to controls (17 RCTs; N = 2408; relative risk (RR) = 0.66; 95% confidence interval (CI) 0.51 to 0.85; number needed to treat for an additional beneficial outcome (NNTB) = 13; CoE: moderate). In infants < 29 weeks' gestation, STC significantly reduced the risk of BPD compared to controls (6 RCTs, N = 980; RR 0.63; 95% CI 0.47 to 0.85; NNTB = 8; CoE: moderate).ConclusionsCompared to controls, STC may be a more efficacious and safe method of surfactant delivery in preterm infants with RDS, including infants < 29 weeks' gestation.

Project description:ObjectiveThis study aimed to estimate the effect of antenatal corticosteroid administration on neonatal mortality and morbidity in preterm small-for-gestational age infants through a systematic review and meta-analysis.Data sourcesA predefined, systematic search was conducted through Ovid MEDLINE, Embase, Scopus, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trial Registry Platform, and ClinicalTrials.gov yielding 5324 articles from 1970 to 2019.Study eligibility criteriaEligible studies compared neonatal morbidity and mortality among small-for-gestational age infants delivered preterm who received antenatal corticosteroids with those who did not.MethodsThe primary outcome was neonatal mortality. Secondary outcomes were respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage and periventricular leukomalacia, bronchopulmonary dysplasia or chronic lung disease of prematurity, or neonatal sepsis. We assessed heterogeneity by means of Higgins I2 statistic and Cochran's Q test and calculated pooled odds ratios with 95% confidence intervals using random effects models.ResultsA total of 16 observational cohort and case-control studies published from 1995 to 2018 met the selection criteria for the systematic review and included 8989 preterm small-for-gestational age infants. Antenatal corticosteroid administration was explicitly reported among 8376 small-for-gestational age infants; 4631 (55.3%) received antenatal corticosteroids and 3741 (44.7%) did not. Of note, 13 studies including 6387 preterm small-for-gestational age infants were then included in the meta-analysis. Neonatal mortality was significantly lower among infants who received antenatal corticosteroids than those who did not (12 studies: 12.8% vs 15.1%; pooled odds ratio, 0.63; 95% confidence interval, 0.46-0.86), with significant heterogeneity between studies (I2=55.1%; P=.011). There was no significant difference in respiratory distress syndrome (12 studies: odds ratio, 0.89; 95% confidence interval, 0.69-1.15), necrotizing enterocolitis (7 studies: odds ratio, 0.93; 95% confidence interval, 0.70-1.22), intraventricular hemorrhage and periventricular leukomalacia (10 studies: odds ratio, 0.82; 95% confidence interval, 0.56-1.20), bronchopulmonary dysplasia or chronic lung disease of prematurity (8 studies: odds ratio, 1.11; 95% confidence interval, 0.88-1.41), or neonatal sepsis (6 studies: odds ratio, 1.13; 95% confidence interval, 0.86-1.49).ConclusionThese data indicate that antenatal corticosteroid administration reduces neonatal mortality in small-for-gestational age infants delivered preterm, with no apparent effect on neonatal morbidity. This supports the use of antenatal corticosteroids to reduce neonatal mortality in pregnancies with small-for-gestational age infants at risk of preterm birth.
