Abstract
Significant racial and ethnic disparities exist in birth outcomes and complications related to prematurity. However, little is known about racial and ethnic variations in health outcomes after premature infants are discharged from the neonatal intensive care unit (NICU). We propose a novel, equity-focused conceptual model to guide future evaluations of post-discharge outcomes that centers on a multi-dimensional, comprehensive view of health, which we call thriving. We then apply this model to existing literature on post-discharge inequities, revealing a need for rigorous analysis of drivers and strength-based, longitudinal outcomes.

Abstract
BACKGROUND AND AIMS To evaluate and compare gastro-esophageal reflux (GER) symptom scores with pH-impedance and test the effects of acid-suppressive medications with or without feeding modifications on pH-impedance in high-risk infants. METHODS Infant Gastroesophageal Reflux Questionnaire Revised (I-GERQ-R) and 24-hour pH-impedance data were analyzed from 94 infants evaluated in a tertiary care setting for GER disease. Longitudinal data from 40 infants that received randomized GER therapy (proton pump inhibitor [PPI] with or without feeding modifications) for 4 weeks followed by 1-week washout were analyzed. Relationships between I-GERQ-R and pH-impedance metrics (acid reflux index, acid and bolus GER events, distal baseline impedance, and symptoms) were examined and effects of treatments compared. RESULTS (A) Correlations between I-GERQ-R and pH-impedance metrics were weak. (B) I-GERQ-R sensitivity, specificity, and positive predictive values were suboptimal when correlated with pH-impedance metrics. I-GERQ-R negative predictive value (NPV) was high for acid symptom-association probability (NPV = 84%) and distal baseline impedence (NPV = 86%) thresholds. (C) PPI with feeding modifications (vs PPI alone) did not alter pH-impedance metrics or symptom scores (P > .05); however, bolus clearance metrics worsened for both treatment groups (P < .05). CONCLUSIONS In high-risk infants (1) I-GERQ-R may be a helpful clinical screening tool to exclude acid-GER disease diagnosis and minimize unnecessary acid-suppressive treatment, but further testing is needed for diagnosis. (2) Acid-suppressive therapy with feeding modifications has no effect on symptom scores or pH-impedance metrics. Clearance of refluxate worsened despite PPI therapy, which may signal development of pharyngoesophageal dysmotility and persistence of symptoms. (3) Placebo-controlled trials are needed in high-risk infants with objective pH-impedance criteria to determine efficacy, safety, and underlying mechanisms. Clinicaltrials.gov ID: NCT02486263.

Abstract
BACKGROUND Current recommendations do not support the use of anti-reflux medications to treat gastro-oesophageal reflux disease (GORD) among preterm infants. OBJECTIVE To describe the prevalence of GORD and the use of anti-reflux medications amongst very preterm infants (<32 weeks' gestational age (GA)) in neonatal units in England and Wales. DESIGN Retrospective cohort study using the National Neonatal Research Database. RESULTS Among 58,108 infants [median GA (IQR) 29 (27-30) weeks], 15.8% (n = 9191) had a diagnosis of GORD and 36.9% (n = 12,446) received anti-reflux medications. Those who received anti-reflux medications were more preterm [GA, median (IQR): medications, 28 (26-30) vs. no medications, 30 (28-31); p < 0.001] and had lower birth weight [mean (SD): medications, 1124 g (354) vs. no medications, 1265 g (384); p < 0.001]. Most (57%, n = 12,224) received Gaviscon, or Histamine-2 Receptor Antagonist (H2RA) (56%, n = 11,959). Over time, prokinetic use has declined substantially, the use of H2RAs and Gaviscon has reduced although they continue to be used frequently, whilst the use of PPIs has increased. CONCLUSIONS Anti-reflux medications are frequently prescribed in very preterm infants, despite evidence to suggest that they are not effective and may be harmful. Clear guidelines for diagnosing GORD and the use of anti-reflux medications are required to rationalise the pharmacological management of GORD in preterm infants. IMPACT Anti-reflux medications are frequently prescribed, often without a diagnosis of gastro-oesophageal reflux disease, to very preterm infants while in the neonatal unit and at discharge. Half of the infants born at <28 weeks' gestational age receive anti-reflux medications in hospital and a quarter are discharged home on them. Although the use of prokinetics declined following alerts of adverse events, histamine2-receptor antagonists and alginates such as Gaviscon continue to be used and the use of proton-pump inhibitors has increased more than 2-fold.

Abstract
A frequent challenge in Neonatology is the high frequency of spontaneously occurring hypoxemic events, a majority of which are associated with apnea or hypoventilation. These episodes present a challenge for caregivers and families as they frequently delay discharge of preterm infants. Supplemental oxygen, respiratory support, and caffeine therapy are widely used as therapeutic approaches, but challenges remain regarding their precise indications. Future clinical practice should be directed by an evidence-based approach including automated supplemental oxygen, minimizing the use of medications for gastroesophageal reflux, optimal timing and dosage of caffeine therapy, and standardization of alarm limits and discharge monitoring protocols.

Abstract
Gastroesophageal reflux (GER) is a functional self-limiting condition in neonates. When pathologic, it is called GER disease (GERD). There are wide variations in the management of signs, symptoms, and complications associated with GERD in the neonatal intensive care unit (NICU). Evidence does not support an empiric trial of GERD medications as a diagnostic tool or therapy in premature infants. Methods A multidisciplinary team developed evidence-based clinical practice guidelines (CPG) for GERD management. Process improvement included developing a GERD management algorithm, electronic order sets, and education for all providers. Multiple plan-do-study-act cycles done. Results Implementation of standardized GERD management guideline, decreased the overall use of antireflux medications from baseline, 15.1%-6.8% [χ2 (1, N = 1259) = 12.98, P < 0.001]. There was elimination of GERD medication use in preterm from baseline of 19.3% [χ2 (1, N = 220) = 12.18, P < 0.001]. The most frequently used GERD medication was lansoprazole, with an incorrect initial dosing rate of 55.0% that deceased to zero [χ2 (1, N = 33) = 10.73, P = 0.001]. Appropriate testing with PH probe with 24-hour multichannel impedance was observed (17.1%-28.0%) identifying patients with correct GERD diagnosis [χ2 (1, N = 101) = 1.41, P = 0.236]. Length of stay for GERD patient's improved from a median of 89-53 days. Conclusion Standardizing clinical management leads to best practices for GERD management with appropriate diagnostic testing, eliminating incorrect medication dosing, and improved patient safety with value-based outcomes.

Abstract
OBJECTIVE To evaluate the clinical usefulness of a non-invasive accelerometric device to diagnose GER in preterm babies. STUDY DESIGN An accelerometer was taped over the sub-xiphoid process in 110 preterm (GA 29.6 ± 3.3 wk) infants (133 studies). Low frequency, sub-audible signals were captured via digital recording (sampling rate 200 Hz), then re-sampled (rate = 60 Hz) to create a spectrogram (focused range 0-30 Hz). Mean amplitude in the focused range was calculated. RESULTS Of 85 studies with simultaneous pH-metry and accelerometry, 18 had concurrent positive and 23 had concurrent negative scores, 42 had negative pH scores when accelerometry was positive (≥1 µV), consistent with non-acid reflux. Eleven infants at high risk of aspiration received surgical interventions. All but 1 had negative pH scores while 10/11 had positive accelerometry. CONCLUSIONS The non-invasiveness of this accelerometric technique allows for GER screening and for repeated testing to assess efficacy of interventions.

Abstract
OBJECTIVE The objective of this study is to examine the relationship between neonatal risk factors and feeding difficulties (FDs) in the NICU and the impact of FD on neurodevelopmental (ND) outcome in ELGA infants. STUDY DESIGN Two hundred and eighteen ELGA infants (59 FDs and 159 no-FDs) were compared for neonatal morbidities, feeding milestones, and Bayley-III scores at 8 and 20 mo CA. Multiple regression analyses adjusted for the effect of risk factors on FD and ND outcome. RESULTS Twenty-seven percent of infants had FD. Postmenstrual age (PMA) at start of oral feeds was the only predictor of FD. At 8 mo CA, FD was the strongest predictor of cognitive <85 (p = 0.018) and motor index <70 (p = 0.019). In linear regression, PMA at start of oral feeds was the only predictor of 8 mo cognitive and motor index (p = 0.006). FD did not predict ND outcome at 20 months CA. CONCLUSIONS FDs are common in ELGA infants and are associated with worse cognitive and motor outcomes in the first year of life.

Abstract
OBJECTIVE Gastroesophageal reflux disease (GERD) in premature neonates may manifest as apnea, bradycardia, growth failure, aspiration, or feeding intolerance. Erythromycin ethylsuccinate (EES), is often used as a pro-kinetic in the management of GERD, despite lack of evidence or safety from randomized controlled trials. We sought to study the efficacy of enteral EES at a dose of 50 mg · kg · day in decreasing the frequency of gastroesophageal reflux events as determined by pH-multichannel intraluminal impedance (pH-MII) monitoring. METHODS In a randomized, double-blind, placebo-controlled trial, eligible premature neonates with clinical signs of GERD underwent 24-hour pH-MII monitoring. If >5 reflux events were identified on pH-MII, then subjects were randomized to receive either EES or placebo. Repeat 24-hour pH-MII was performed on day 7 of study treatment and compared to initial pH-MII. RESULTS Forty-three premature neonates were enrolled. Of those, 31 neonates were randomized, 15 to EES and 16 to placebo with a median (IQR) pretreatment total reflux events per 24 hours of 23 (16-40) and 29 (12-40), respectively. Day 7 total events per 24 hours decreased by 4 events in the EES group to 19 (15-33) and by 10 events in the placebo group to 19 (11-26) (P = 0.09). There were no differences in pretreatment and day 7 acidic and nonacidic reflux, proximal reflux, total or percent reflux time, median or longest bolus clearance time, or nurse-reported apnea events between groups. CONCLUSIONS Enteral EES did not decrease reflux events on 24-hour pH-MII at the dose studied. Therefore, it may be ineffective in the treatment of GERD in premature neonates.

Abstract
Gastroesophageal reflux (GER), generally defined as the passage of gastric contents into the esophagus, is an almost universal phenomenon in preterm infants. It is a common diagnosis in the NICU; however, there is large variation in its treatment across NICU sites. In this clinical report, the physiology, diagnosis, and symptomatology in preterm infants as well as currently used treatment strategies in the NICU are examined. Conservative measures to control reflux, such as left lateral body position, head elevation, and feeding regimen manipulation, have not been shown to reduce clinically assessed signs of GER in the preterm infant. In addition, preterm infants with clinically diagnosed GER are often treated with pharmacologic agents; however, a lack of evidence of efficacy together with emerging evidence of significant harm (particularly with gastric acid blockade) strongly suggest that these agents should be used sparingly, if at all, in preterm infants.

Abstract
BACKGROUND Cardiorespiratory (CR) events (apnea, bradycardia, oxygen desaturation) and gastroesophageal reflux (GER) symptoms often coexist in infants admitted to Neonatal Intensive Care Unit, leading to over-prescription of drugs and delayed discharge. We aimed to evaluate the relationships between CR and GER events. METHODS The temporal associations between CR and GER events were analyzed in symptomatic infants who underwent synchronized CR and pH-impedance monitoring. The symptom association probability (SAP) index was used to identify infants with a significant number of temporal associations. Gastroesophageal reflux characteristics and the chronological sequence of CR and GER events occurring within 30 seconds of each other were evaluated according to SAP index. KEY RESULTS Of the 66 infants enrolled, aged 29 (18-45) days, 58 had CR events during monitoring. From these 58 patients, a total of 1331 CR events and 5239 GER (24% acidic) were detected. The SAP index was positive in seven (12%) infants. These infants had greater GER frequency, duration, and proximal extent (P < .05). The number of temporal associations was 10 times greater in the positive SAP group. Gastroesophageal reflux events preceded CR events in 83% of these associations. These GER events had a higher proximal extent (P = .004), but showed no differences in pH values. CONCLUSIONS & INFERENCES The simultaneous evaluation of CR and GER events could be useful to identify infants with severe GER and significant temporal associations between these events. Treatment of GER could be indicated in these infants, but as the GER events involved are mainly non-acidic, empirical treatment with antacids is, often, inappropriate.

Abstract
PURPOSE The purpose of this study was to determine effectiveness of a midliner positioning system (MPS, Tortle Midliner) for preventing dolichocephaly. METHODS This was a nonrandomized, prospective study of 30 premature infants (study cohort, SC) using an MPS compared with a retrospective study cohort (RSC) of 65 infants who received standard of care intervention. RESULTS RSC baseline cranial index (CI) of 80% and final CI of 77% significantly decreased over an average 5.5 weeks (P < .0001). The SC baseline CI and the final CI were both 79% over an average 5.7 weeks, indicating no significant difference between CI measures (P = .6). Gestational age, birth weight, reflux, time on continuous positive airway pressure, and time in a supine position were not associated with dolichocephaly. CONCLUSIONS The SC developed less cranial molding (ie, had greater CI), compared with the RSC. A larger randomized study is needed to recommend routine use of MPS for prevention and/or treatment of cranial molding in premature infants.

Abstract
OBJECTIVES This study sought to characterize trends in the diagnosis of apnea, associated comorbidities and complications, and 30-day readmission rates in preterm singleton infants. SUBJECTS AND METHODS The study design was a retrospective, longitudinal, observational study. 2003-2014 New York State Statewide Planning and Research Cooperative System and New York City Vital Statistics databases were merged identifying preterm live singleton births. Hospitalizations of preterm newborns with and without apnea were compared; multivariable logistic regression and log-linear Poisson regression models applied. RESULTS Of 1,384,013 singleton births, 7.5% were identified as preterm. While relative risk of preterm birth rates declined (RR = 0.987, 95% CI = 0.982-0.991), the diagnosis of apnea increased significantly (RR = 1.069, 95% CI = 1.049-1.089). Multivariable analysis identified two apnea predictors, gastric reflux (OR = 3.19, 95% CI = 2.80-3.63) and early gestational age (OR = 0.83 for 1 week GA increase, 95% CI = 0.82-0.84). Preterm newborns with apnea were more likely to be readmitted within the first 30 days and total charges were 5.4 times higher. CONCLUSIONS While the preterm birth rate has declined the rate of diagnosis of apnea with associated comorbidities and complications has increased. Given the additional findings of higher 30-day readmission rates and charges, more multidisciplinary research appears warranted to identify ways to optimize the quality of high risk newborn care.

Abstract
AIM To determine whether a pH probe or multichannel intraluminal impedance (MII) more frequently detected gastro-oesophageal reflux and test the hypothesis that acid reflux was associated with lower baseline impedance. METHODS A prospective study of infants in whom reflux was suspected and evaluated using combined pH and multichannel impedance. Studies were considered abnormal if the acid index was >10% or there were >79MII reflux events in 24 hours. The acid index was the percentage of total study time with a pH RESULTS Forty-two infants [median gestational age 31 (range 23-42) weeks] were assessed. Only nine infants (21%) had abnormal studies, seven detected by pH monitoring, one by MII monitoring and one by both techniques (p = 0.04). After correcting for gestational age and post-natal age, baseline impedance remained negatively correlated with the acid index (r = -0.34, p = 0.038) and the maximum ACT (r = -0.44, p = 0.006). CONCLUSION Clinical suspicion of reflux was frequently incorrect, and reflux was more frequently detected by a pH probe. The inverse relationship of acid reflux to baseline impedance suggests that mucosal disruption may result from acid reflux in this population.

Abstract
Gastroesophageal reflux is a normal physiologic occurrence that is common throughout infancy and usually resolves on its own. Infrequently, reflux causes complications and turns into gastroesophageal reflux disease (GERD), which may warrant intervention. Available interventions vary in invasiveness and supporting data may be lacking for efficacy and safety. Nonpharmacologic interventions are first-line therapy for GERD in infants, whereas pharmacologic and surgical approaches are controversial. Efficacy data are limited for pharmacologic strategies for infantile GERD and safety data have demonstrated serious risks, especially in younger infants. Utilization of these medications should be approached cautiously in this population, if appropriate diagnostic techniques determine acid suppression could be beneficial. A robust monitoring plan with frequent reassessment of need for therapy may optimize benefit and minimize risk.

Abstract
AIM In 2004, wide variation in the investigation and management of gastro-oesophageal reflux (GOR) of infants on UK major neonatal units was demonstrated. Our aim was to resurvey neonatal practitioners to determine current practice and whether it was now evidence based. METHODS A questionnaire was sent to all 207 UK neonatal units. RESULTS Responses were obtained from 84% of units. The most frequent 'investigation' was a trial of therapy (83% of units); pH studies were used in 38%, upper GI contrast studies in 19% and multichannel intraluminal impedance (MII)/pH studies in 5%. Only six units suggested a threshold for an abnormal pH study and two units for an abnormal MII study. Infants were commenced on antireflux medication without investigation always in 32% of units, often in 29%, occasionally in 19% and only never in 1%. Gaviscon was used as first line treatment in 60% of units, and other medications included ranitidine in 53%, thickening agents in 27%, proton pump inhibitors in 23%, domperidone in 22% and erythromycin in 6%. CONCLUSION There remains a wide variation in diagnostic and treatment strategies for infants with suspected GOR on neonatal intensive care units, emphasising the need for randomised trials to determine appropriate GOR management.

Abstract
OBJECTIVES Antacid medications are frequently administered to preterm infants. These medications can change gastric pH levels and can affect regular gastrointestinal function and gut micro-bacterial flora. We hypothesized that preterm infants exposed to antacid medications are at a greater risk of necrotizing enterocolitis (NEC) and sepsis, and set out to determine any association, as well as to assess the clinical efficacy of these medications. MATERIALS AND METHODS Retrospective chart review of preterm infants ≤30 weeks' gestational age or birth weight ≤1250 g over a 2-year period at New York University Langone Medical Center. Subjects were divided into two groups: those who had been treated with antacid medications and those who had not. We then examined for any difference in NEC (≥Bell stage 2) or culture proven sepsis. RESULTS The study comprised 65 eligible neonates, 28 in antacid treatment group and 37 in control. The incidence of NEC (21.4% vs. 2.7%, P=0.04) was significantly higher in the antacid group, but these infants tended to be born more prematurely than control subjects. There was a trend toward more culture proven sepsis cases in the antacid group. We found no difference in signs generally associated with neonatal reflux (apnea, bradycardia, and desaturation events) in subjects treated with antacid medications after treatment began. CONCLUSIONS Treatment of preterm infants with antacid medications is potentially associated with a higher risk of NEC, and possibly sepsis, while appearing to provide little benefit.

Effects of Esophageal Acidification on Troublesome Symptoms: An Approach to Characterize True Acid GERD in Dysphagic Neonates. Dysphagia 2017; 32:509-519.

Abstract
To quantify and compare maximal extent (height) of acid reflux events (AREs) on symptom generation in dysphagic neonates. Dysphagic neonates (N = 53), born at 30 ± 5.3 weeks gestation, underwent 24-hour pH-impedance study for the evaluation of troublesome symptoms purported to be due to gastroesophageal reflux disease (GERD). AREs (pH < 4 for >4 s) detected by impedance (Z) were categorized by maximal extent as refluxate reaching distal (Z6, Z5), middle (Z4, Z3), or proximal (Z2, Z1) impedance channels. AREs reaching the pH sensor only were categorized as distal. Symptom correlation (%, symptom index, symptom sensitivity index, and symptom associated probability) and temporal characteristics (clearance times) of AREs were analyzed using linear mixed and GEE models comparing height categories presented as mean ± SEM, median (IQR), and OR (95% CI). Of the 2003 AREs, 1) distal extent AREs (n = 1642) had increased frequency (p < 0.05), decreased ACT (p < 0.05), and decreased acidity (p < 0.05); 2) in middle and proximal AREs, acid clearance was longer than bolus clearance, (p < 0.01); and 3) the odds of having cardiorespiratory (cough or sneeze) symptoms are increased with proximal and middle AREs (p < 0.05). Most proximal ascent of AREs into middle or proximal esophagus likely activates protective aerodigestive reflexes (peristalsis) or vigilant states to facilitate bolus and chemical clearance. Heightened esophageal sensitivity, acid neutralization delays, or clearance mechanism delays may accentuate multi-systemic troublesome symptoms.

Abstract
OBJECTIVE To test the hypothesis that oral feeding at first neonatal intensive care unit discharge is associated with less neurodevelopmental impairment and better feeding milestones compared with discharge with a gastrostomy tube (G-tube). STUDY DESIGN We studied outcomes for a retrospective cohort of 194 neonates <37 weeks' gestation referred for evaluation and management of feeding difficulties between July 2006 and July 2012. Discharge milestones, length of hospitalization, and Bayley Scales of Infant Development-Third Edition scores at 18-24 months were examined. χ2, Mann-Whitney U, or t tests and multivariable logistic regression models were used. RESULTS A total of 60% (n = 117) of infants were discharged on oral feedings; of these, 96% remained oral-fed at 1 year. The remaining 40% (n = 77) were discharged on G-tube feedings; of these, 31 (40%) remained G-tube dependent, 17 (22%) became oral-fed, and 29 (38%) were on oral and G-tube feedings at 1 year. Infants discharged on a G-tube had lower cognitive (P <.01), communication (P = .03), and motor (P <.01) composite scores. The presence of a G-tube, younger gestation, bronchopulmonary dysplasia, or intraventricular hemorrhage was associated significantly with neurodevelopmental delay. CONCLUSIONS For infants referred for feeding concerns, G-tube evaluations, and feeding management, the majority did not require a G-tube. Full oral feeding at first neonatal intensive care unit discharge was associated with superior feeding milestones and less long-term neurodevelopmental impairment, relative to full or partial G-tube feeding. Evaluation and feeding management before and after G-tube placement may improve long-term feeding and neurodevelopmental outcomes.

Dose-Finding Study of Omeprazole on Gastric pH in Neonates with Gastro-Esophageal Acid Reflux Using a Bayesian Sequential Approach. PLoS One 2016; 11:e0166207.

Abstract
Objective Proton pump inhibitors are frequently administered on clinical symptoms in neonates but benefit remains controversial. Clinical trials validating omeprazole dosage in neonates are limited. The objective of this trial was to determine the minimum effective dose (MED) of omeprazole to treat pathological acid reflux in neonates using reflux index as surrogate marker. Design Double blind dose-finding trial with continual reassessment method of individual dose administration using a Bayesian approach, aiming to select drug dose as close as possible to the predefined target level of efficacy (with a credibility interval of 95%). Setting Neonatal Intensive Care unit of the Robert Debré University Hospital in Paris, France. Patients Neonates with a postmenstrual age ≥ 35 weeks and a pathologic 24-hour intra-esophageal pH monitoring defined by a reflux index ≥ 5% over 24 hours were considered for participation. Recruitment was stratified to 3 groups according to gestational age at birth. Intervention Five preselected doses of oral omeprazole from 1 to 3 mg/kg/day. Main outcome measures Primary outcome, measured at 35 weeks postmenstrual age or more, was a reflux index <5% during the 24-h pH monitoring registered 72±24 hours after omeprazole initiation. Results Fifty-four neonates with a reflux index ranging from 5.06 to 27.7% were included. Median age was 37.5 days and median postmenstrual age was 36 weeks. In neonates born at less than 32 weeks of GA (n = 30), the MED was 2.5mg/kg/day with an estimated mean posterior probability of success of 97.7% (95% credibility interval: 90.3–99.7%). The MED was 1mg/kg/day for neonates born at more than 32 GA (n = 24). Conclusions Omeprazole is extensively prescribed on clinical symptoms but efficacy is not demonstrated while safety concerns do exist. When treatment is required, the daily dose needs to be validated in preterm and term neonates. Optimal doses of omeprazole to increase gastric pH and decrease reflux index below 5% over 24 hours, determined using an adaptive Bayesian design differ among neonates. Both gestational and postnatal ages account for these differences but their differential impact on omeprazole doses remains to be determined.

Abstract
OBJECTIVES To describe the epidemiology and management of gastroesophageal reflux (GER) medications started in the first year of life for premature infants. METHODS Retrospective review of a cohort of infants ≤35 weeks' gestation presenting for care by 168 days of age to a 30-site network between 2005 and 2009 (n = 2217) and followed to 3 years of age. Medication frequency, types, and duration of use were assessed. Logistic regression identified factors associated with treatment. RESULTS Thirty-seven percent (812) were prescribed GER medications with 77% begun after NICU discharge. Ninety percent (727) received histamine-2 receptor antagonists, 33% (269) proton pump inhibitors, 22% (182) prokinetics; 40% (325) received >1 medication. Outpatient medication was initiated at 95 ± 69 days of life for total of 294 ± 249 days (interquartile ratio: 117-359). Feeding issues (adjusted odds ratio [aOR] 2.05, 95% confidence interval [CI]: 1.24-3.39) were associated with outpatient initiation. Forty-three percent (322) of infants started before 6 months were still on at 1 year of age associated with gestational age <32 weeks (aOR 1.76, 95% CI: 1.16-2.67), chronic lung disease (aOR 2.59, 95% CI: 1.29-5.22), and reactive airways disease (aOR 1.67, 95% CI: 1.05-2.65). CONCLUSIONS Of the 37% of the cohort on GER medications, 77% were started after NICU discharge with prolonged use of medications. Feeding difficulties were associated with starting medication and markers of chronic lung disease with continuation of treatment. With uncertain evidence of efficacy, use of these medications in a high-risk population should be carefully evaluated.

Abstract
Background and Objectives. Antacids are often prescribed to preterm infants due to misdiagnosis of gastro-oesophageal reflux. This suppresses gastric acidity, a major defence mechanism against infection. This study aims to determine if ranitidine and omeprazole use in very low birth weight (VLBW) neonates, <1500 grams, is associated with increased risk of late onset sepsis, necrotising enterocolitis (NEC), and mortality. Methods. Retrospective analysis was conducted on neonates, <1500 grams, born and admitted into the Neonatal Intensive Care Unit at The Canberra Hospital during the period from January 2008 to December 2012. Information regarding late onset sepsis, NEC, mortality, ranitidine/omeprazole use, and other neonatal/hospital factors was collected for each neonate. Results. 360 neonates were evaluated, 64 received ranitidine and/or omeprazole, and 296 had not. There were no statistically significant differences in incidence of late onset sepsis (OR = 0.52, CI = 0.24-1.1, and p = 0.117), NEC Stage 2 and above (OR = 0.4, CI = 0.05-3.2, and p = 0.7), or mortality (OR = 0.35, CI = 0.08-1.5, and p = 0.19) between the two groups. After adjusting significant differences in neonatal and hospital factors, risk of late onset sepsis was significantly lower in those that received ranitidine/omeprazole (OR = 0.28, CI = 0.13-0.65, and p = 0.003). Conclusions. Ranitidine and omeprazole use in VLBW preterm infants may not be associated with an increased risk of infection, NEC, and mortality.

Abstract
Gastroesophageal reflux is a common phenomenon in infants, but the differentiation between gastroesophageal reflux and gastroesophageal reflux disease can be difficult. Symptoms are non-specific and there is increasing evidence that the majority of symptoms may not be acid-related. Despite this, gastric acid inhibitors such as proton pump inhibitors are widely and increasingly used, often without objective evidence or investigations to guide treatment. Several studies have shown that these medications are ineffective at treating symptoms associated with reflux in the absence of endoscopically proven oesophagitis. With a lack of evidence for efficacy, attention is now being turned to the potential risks of gastric acid suppression. Previously assumed safety of these medications is being challenged with evidence of potential side effects including GI and respiratory infections, bacterial overgrowth, adverse bone health, food allergy and drug interactions.

Abstract
Comprehensive guidelines for the diagnosis and management of gastro-esophageal reflux (GER) and GER disease (GERD) were developed by the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition. GERD is reflux associated with troublesome symptoms or complications. The recognition of GER and GERD is relevant to implement best management practices. A conservative management is indicated in infants with uncomplicated physiologic reflux. Children with GERD may benefit from further evaluation and treatment. Since the publications of the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition guidelines in 2009, no important novelties in drug treatment have been reported. Innovations are mainly restricted to the management of regurgitation in infants. During the last 5 years, pros and cons of multichannel intraluminal impedance have been highlighted. However, overall 'not much has changed' in the diagnosis and management of GER and GERD in infants and children.

Abstract
BACKGROUND Histamine-2 receptor (H2) blockers are often used in very low birth weight infants despite lack of population specific efficacy and safety data. AIMS We sought to describe safety and temporal trends in histamine-2 receptor (H2) blocker use in hospitalized very low birth weight (VLBW) infants. STUDY DESIGN We conducted a retrospective cohort study using a clinical database populated by an electronic health record shared by 348 neonatal intensive care units in the United States. SUBJECTS We included all VLBW infants without major congenital anomalies. OUTCOME MEASURES We used multivariable logistic regression with generalizing estimating equations to evaluate the association between days of H2 blocker exposure and risk of: 1) death or necrotizing enterocolitis (NEC); 2) death or sepsis; and 3) death, NEC, or sepsis. RESULTS Of 127,707 infants, 20,288 (16%) were exposed to H2 blockers for a total of 6,422,352days. Median gestational age for infants exposed to H2 blockers was 27weeks (25th 75th percentile 26, 29). H2 blocker use decreased from 18% of infants in 1997 to 8% in 2012 (p<0.001). On multivariable analysis, infants were at increased risk of the combined outcome of death, NEC, or sepsis on days exposed to H2 blockers (odds ratio=1.14) (95% confidence interval 1.08, 1.19). CONCLUSIONS H2 blocker use is associated with increased risk of the combined outcome of death, NEC, or sepsis in hospitalized VLBW infants.

OBJECTIVE To determine treatment frequency and duration of histamine-2 receptor antagonist (H2RA)/proton pump inhibitor (PPI) use among infants hospitalized within US children's hospital neonatal intensive care units and evaluate diagnoses/demographic factors associated with use. STUDY DESIGN We retrospectively analyzed a cohort of neonatal intensive care unit infants admitted to 43 US children's hospitals within the Pediatric Health Information System database between January 2006 and March 2013 to determine H2RA/PPI treatment frequency, timing/duration of treatment, factors associated with use, percent of infants remaining on treatment at discharge, and interhospital prescribing variation. We used a modified Poisson regression to calculate the adjusted probability of infants ever receiving H2RAs/PPIs in relation to diagnosis, gestation, and sex. RESULTS Of the 122 002 infants evaluated, 23.8% (n = 28 989) ever received an H2RA or PPI; 19.0% received H2RAs (n = 23 187), and 10.5% (n = 12 823) received PPIs. Extremely preterm infants and term infants were the most likely to receive H2RA and PPI treatment. Infants with gastroesophageal reflux disease (relative risk [RR] = 3.13) and congenital heart disease (RR = 2.41) had the highest H2RA/PPI treatment probabilities followed by those with an ear, nose, and throat diagnosis (RR = 2.34; P < .05). The majority of treated infants remained treated at discharge. CONCLUSIONS Despite limited evidence and increasing safety concerns, H2RAs/PPIs are frequently prescribed to extremely preterm neonates and those with congenital anomalies and continued through discharge. Our findings support the need for innovative studies to examine the comparative effectiveness and safety of H2RA/PPIs vs no treatment in these high-risk neonatal populations.

Abstract
OBJECTIVE Prokinetic medications are used in premature infants to promote motility and decrease time to full enteral feeding. Erythromycin and metoclopramide are the most commonly used prokinetic medications in the neonatal intensive care unit (NICU), but their safety profile is not well defined. METHODS We conducted a large retrospective cohort study using data from 348 NICUs managed by the Pediatrix Medical Group. All of the infants exposed to ≥1 dose of erythromycin, metoclopramide, or both, from a cohort of 8,87,910 infants discharged between 1997 and 2012 were included. We collected laboratory and clinical information while infants were exposed to erythromycin or metoclopramide and described the frequency of laboratory abnormalities and clinical adverse events (AEs). RESULTS Metoclopramide use increased from 1997 to 2005 and decreased from 2005 to 2012, whereas erythromycin use remained stable. Erythromycin use was most often associated with a diagnosis of feeding problem (40%), whereas metoclopramide was most often associated with a diagnosis of gastroesophageal reflux (59%). The most common laboratory AE during exposure to erythromycin or metoclopramide was hyperkalemia (8.6/1000 infant days on erythromycin and 11.0/1000 infant days on metoclopramide). Incidence of pyloric stenosis was greater with erythromycin than with metoclopramide (10/1095, 0.9% vs 76/19,001, 0.4%; P = 0.01), but odds were not significantly increased after adjusting for covariates (odds ratio 0.52, 95% confidence interval [CI] 0.26-1.02, P = 0.06). More infants experienced an AE while treated with metoclopramide than with erythromycin (odds ratio 1.21, 95% CI 1.03-1.43). CONCLUSIONS Metoclopramide was associated with increased risk of AEs compared with erythromycin. Studies are needed to confirm safety and effectiveness of both the drugs in infants.

Abstract
OBJECTIVES Gastroesophageal reflux (GER) is a frequently occurring condition in infants capable of causing distressing symptoms. The aim of our study is to evaluate the efficacy of Mg alginate plus simethicone (Gastrotuss Baby, DMG Italia SRL, Pomezia, Italy), compared with rice-starch-thickened formula or with reassurance alone, in the treatment of GER in infants. METHODS The present randomized controlled trial was conducted in full-term infants affected by symptoms suggestive of GER, evaluated through a validated questionnaire (Infant Gastroesophageal Reflux Questionnaire Revised). The patients were randomized into 3 groups according to treatment (group A: Mg alginate plus simethicone; group B: thickened formula; group C: reassurance with lifestyle changes). Evaluation of symptom scores was performed after 1 month (T1) and 2 months (T2). RESULTS A total of 64 (85.3%) of 75 enrolled infants (median age 5 months; range 1-10) concluded the study. After 1 month of treatment (T1), infants treated with Mg alginate plus simethicone showed a statistically significant improvement in symptoms compared with the thickened formula and reassurance (P < 0.03, <0.0001, respectively). At the end of the study, all 3 groups of patients showed a significant reduction in symptom scores (P < 0.002, <0.038, <0.03, respectively). Median symptom score values were more significantly reduced in group A than in group B and in group C (group A vs group B P < 0.002; group A vs group C P < 0.0001; group B vs group C P < 0.001). CONCLUSIONS Mg alginate plus simethicone seems to be more efficacious on GER symptom scores than thickened formula and reassurance with lifestyle changes alone.

Can MII-pH values predict the duration of treatment for GERD in preterm infants? Early Hum Dev 2014; 90:501-5.

Abstract
BACKGROUND Little is known regarding the prognostic role of Multichannel Intraluminal Impedance and pH monitoring (MII/pH) parameters in preterm infants with Gastro-Esophageal Reflux Disease (GERD). AIM Our study aimed to evaluate the relationship between MII/pH variables and the duration of pharmacological therapy for GERD, in preterm infants with gestational age (GA) ≤34weeks. SUBJECTS, STUDY DESIGN, OUTCOME MEASURES We retrospectively reviewed data of all newborns with GA ≤34weeks that underwent MII/pH in our Neonatal Intensive Care Unit (NICU) and pharmacological treatment for GERD. We included them in a 12-month follow-up program. MII/pH parameters were used as independent variables and the duration of pharmacological therapy as dependent variable in linear regression models. RESULTS 16 patients (GA 28.4±1.8weeks, BW 1122±427g) were enrolled into the study. Regression analysis performed on all reflux events reported a significant correlation between the duration of pharmacological treatment and MII-BEI (r(2)=0.36, p=0.01) and MII-reflux frequency (r(2)=0.33, p=0.02). Moreover, regression analysis performed on all events classified according to the corresponding pH change - acidic (ac.), weakly acidic (w.ac.) or weakly alkaline (w.a.) - showed a significant correlation between the duration of pharmacological treatment and MII-w.ac.BEI (r(2)=0.26, p=0.05), MII-w.ac. reflux frequency (r(2)=0.44, p=0.01), and MII-proximal w.ac. reflux frequency (r(2)=0.35, p=0.02). No statistically significant correlation was found between pH-Reflux Index and the duration of treatment. CONCLUSION The study shows how, in our population of preterm infants, MII-parameters could have not only a diagnostic role, but also a prognostic value in terms of the duration of pharmacological treatment.

Abstract
Paediatric GERD is complicated to manage, as symptoms are diverse and often difficult to interpret. In infants, regurgitation is a common physiological condition. Nevertheless, when it occurs frequently (>4 times per day) and causes the infant distress, parents often seek medical help. In children 2-10 years of age, GERD is often considered to cause extra-oesophageal symptoms, despite the absence of hard evidence. Diagnostic investigations often lack solid validation and the signs and symptoms of GERD overlap with those of cow's milk protein allergy and eosinophillic oesophagitis. Reassurance, dietary treatment and positional adaptations are recommended for troublesome infant reflux. Anti-acid medication, mainly PPIs, is over-used in infants even though, in many children, reflux is not an acid-related condition. Moreover, evidence is increasing that PPIs cause adverse events such as gastroenteritis and respiratory tract infections. Management in children older than 10 years is similar to that in adults. Using prokinetics to treat nonerosive reflux disease remains only a promising theoretical concept, as no such molecule is currently available. Today, the adverse effects of each prokinetic molecule largely outweigh its potential benefit. Laparoscopic surgery is indicated in children who have life-threatening symptoms or in cases of drug dependence.

Abstract
Feeding intolerance resulting from delayed gastric emptying is common in premature neonates. Metoclopramide (MCP), the most frequently used prokinetic drug in neonates, enhances gastric muscle contractility through inhibition of dopamine receptors. Although its therapeutic benefit is established in adults, limited data are available to support its clinical use in infants. Hypothesizing that developmentally dependent differences are present, we comparatively evaluated the effect of MCP on fundus muscle contractility in newborn, juvenile, and adult rats. The muscle strips were either contracted with electrical field stimulation (EFS) to induce cholinergic nerve-mediated acetylcholine release or carbachol, a cholinergic agonist acting directly on the muscarinic receptor. Although in adult rats MCP increased EFS-induced contraction by 294 ± 122% of control (P < 0.01), no significant effect was observed in newborn fundic muscle. MCP had no effect on the magnitude of the carbachol-induced and/or bethanechol-induced gastric muscle contraction at any age. In response to dopamine, an 80.7 ± 5.3% relaxation of adult fundic muscle was observed, compared with only a 8.4 ± 8.7% response in newborn tissue (P < 0.01). Dopamine D2 receptor expression was scant in neonates and significantly increased in adult gastric tissue (P < 0.01). In conclusion, the lack of MCP effect on the newborn fundic muscle contraction potential relates to developmental differences in dopamine D2 receptor expression. To the extent that these novel data can be extrapolated to neonates, the therapeutic value of MCP as a prokinetic agent early in life requires further evaluation.

Abstract
We tested the hypothesis that the sensory-motor characteristics of aerodigestive reflexes are dependent on stimulus type and volumes, sleep or awake states, and maturation. Thirteen neonates were studied at 33.6 ± 0.5 wk (time 1) and 37.3 ± 0.5 wk (time 2) postmenstrual age using multimodal provocative esophageal manometry concurrent with video polysomnography. Effects of graded volumes (399 infusions at time 1, 430 infusions at time 2) of midesophageal stimulation with air, water, and apple juice on the sensory thresholds and recruitment frequency of upper esophageal sphincter (UES), esophageal body, and lower esophageal sphincter (LES) reflexes were investigated during sleep and awake states. Sensory thresholds for aerodigestive reflexes between maturational stages were similar. Increased frequency recruitment of UES contractile reflex, LES relaxation reflex, and peristaltic reflexes were noted at time 2 (all, P < 0.05). Graded stimulus-response relationships were evident at time 1 and time 2 during awake and sleep states (P < 0.05). Secondary peristalsis vs. esophago-deglutition response proportions during sleep at time 1 vs. time 2 (P = 0.001) and awake vs. sleep at time 2 (P = 0.02) were distinct. We concluded that sensory-motor effects of esophageal mechanosensitivity, osmosensitivity, and chemosensitivity are advanced in sleep with maturation. Sleep further modulates the frequency recruitment and the type of aerodigestive reflexes.

Abstract
OBJECTIVE To determine the practice variance, prevalence, and economic burden of clinically diagnosed gastroesophageal reflux disease (GERD) in preterm infants. METHODS Applying a retrospective cohort study design, we analyzed data from 18 567 preterm infants of 22 to 36 weeks' gestation and >400 g birth weight from the NICUs of 33 freestanding children's hospitals in the United States. GERD prevalence, comorbidities, and demographic factors were examined for their association with average length of stay (LOS) and hospitalization cost. RESULTS Overall, 10.3% of infants received a diagnosis of GERD (95% confidence interval [CI]: 9.8-10.7). There was a 13-fold variation in GERD rates across hospitals (P < .001). GERD diagnosis was significantly (P < .05) associated with bronchopulmonary dysplasia and necrotizing enterocolitis, as well as congenital anomalies and decreased birth weight. GERD diagnosis was associated with $70 489 (95% CI: 62 184-78 794) additional costs per discharge and 29.9 additional days in LOS (95% CI: 27.3-32.5). CONCLUSIONS One in 10 of these premature NICU infants were diagnosed with GERD, which is associated with substantially increased LOS and elevated costs. Better diagnostic and management strategies are needed to evaluate reflux-type symptoms in this vulnerable NICU population.

Abstract
Gastroesophageal reflux (GOR) is very common among preterm infants, due to several physiological mechanisms. Although GOR should not be usually considered a pathological condition, its therapeutic management still represents a controversial issue among neonatologists; pharmacological overtreatment, often unuseful and potentially harmful, is increasingly widespread. Hence, a stepwise approach, firstly promoting conservative strategies such as body positioning, milk thickening, or changes of feeding modalities, should be considered the most advisable choice in preterm infants with GOR. This review focuses on the conservative management of GOR in the preterm population, aiming to provide a complete overview, based on currently available evidence, on potential benefits and adverse effects of nonpharmacological measures. Nonpharmacological management of GOR might represent a useful tool for neonatologists to reduce the use of antireflux medications, which should be limited to selected cases of symptomatic babies.

Abstract
Although gastroesophageal reflux (GER) is a very common phenomenon among preterm infants, its therapeutic management is still an issue of debate among neonatologists. A step-wise approach should be advisable, firstly promoting nonpharmacological interventions and limiting drugs to selected infants unresponsive to the conservative measures or who are suffering from severe GER with clinical complications. Despite of this, a concerning pharmacological overtreatment has been increasingly reported. Most of the antireflux drugs, however, have not been specifically assessed in preterm infants; moreover, serious adverse effects have been noticed in association to their administration. This review mainly aims to draw the state of the art regarding the pharmacological management of GER in preterm infants, analyzing the best piecies of evidence currently available on the most prescribed anti-reflux drugs. Although further trials are required, sodium alginate-based formulations might be considered promising; however, data regarding their safety are still limited. Few piecies of evidence on the efficacy of histamine-2 receptor blockers and proton pump inhibitors in preterm infants with GER are currently available. Nevertheless, a significantly increased risk of necrotizing enterocolitis and infections has been largely reported in association with their use, thereby leading to an unfavorable risk-benefit ratio. The efficacy of metoclopramide in GER's improvement still needs to be clarified. Other prokinetic agents, such as domperidone and erythromycin, have been reported to be ineffective, whereas cisapride has been withdrawn due to its remarkable cardiac adverse effects.

Abstract
Apnea of prematurity and gastroesophageal reflux (GER) are both common occurrences in preterm infants and widely perceived to be causally related. We seek in this review to provide a potential guideline for neonatal GER non-pharmacologic and pharmacologic therapy. Available physiologic data suggest that when there is a temporal relationship apnea may be more likely to predispose to GER via esophageal sphincter relaxation than vice versa. Measurement of multiple intraluminal impedance via esophageal catheter in addition to esophageal pH has enhanced our understanding of GER, although it also did not demonstrate a causal relationship between apnea and GER. The incidence of GER may be modified by thickening feeds and position change without adverse effects. In contrast, pharmacotherapy including acid suppression therapy may have adverse effects and should only be used in infants with clear evidence of clinical benefit.

Abstract
OBJECTIVE To evaluate the relationship between multichannel intraluminal impedance and pH monitoring (MII/pH) values in newborns with symptoms of gastroesophageal reflux disease (GERD) and clinical history in their first 3 years of life. STUDY DESIGN Sixty-four newborns with GERD symptoms who underwent MII/pH in the first weeks of life were enrolled into a clinical follow-up program. Follow-up visits were programmed at 1, 3, 6, 9, 12, 18, 24, and 36 months. Patients were divided into 3 groups according to duration of symptoms: short (1-3 months), medium (4-9 months), and long (>9 months), and MII/pH values in these groups were compared. RESULTS Fifty-three patients completed the 3-year follow-up. The number of patients with GERD symptoms decreased each month. A comparison of MII/pH values of the 3 lifetime symptom groups revealed differences in the impedance bolus exposure index (F = 83; P = .012) and proximal reflux frequency (F = 410; P = .022). These 2 MII variables showed an increasing trend from the short lifetime symptom group to the long lifetime symptom group. Weakly acidic reflux events, but not acidic events, were responsible for these differences. CONCLUSION MII/pH in newborns has prognostic value regarding the duration of GERD symptoms and provides useful information that clinicians may give parents about the prognosis of symptomatic infants. Impedance bolus exposure index and proximal reflux frequency seem to be the variables with the highest predictive value. Weakly acidic reflux events play an important role in determining the duration of GERD symptoms in newborns.

Abstract
Persistent patency of the ductus arteriosus (PDA) is a common problem in preterm infants. The antacid cimetidine is a potent antagonist of the H2 histamine receptor but it also inhibits certain cytochrome P450 enzymes (CYPs), which may affect DA patency. We examined whether cimetidine contributes to PDA and is mediated by CYP inhibition rather than H2 blockade. Analysis of a clinical trial to prevent lung injury in premature infants revealed a significant association between cimetidine treatment and PDA. Cimetidine and ranitidine, both CYP inhibitors as well as H2 blockers, caused relaxation of the term and preterm mouse DA. CYP enzymes that are inhibited by cimetidine were expressed in DA subendothelial smooth muscle. The selective CYP3A inhibitor ketoconazole induced greater DA relaxation than cimetidine, whereas famotidine and other H2 antagonists with less CYP inhibitory effects caused less dilation. Histamine receptors were developmentally regulated and localized in DA smooth muscle. However, cimetidine caused DA relaxation in histamine-deficient mice, consistent with CYP inhibition, not H2 antagonism, as the mechanism for PDA. Oxygen-induced DA constriction was inhibited by both cimetidine and famotidine. These studies show that antacids and other compounds with CYP inhibitory properties pose a significant and previously unrecognized risk for PDA in critically ill newborn infants.

Abstract
BACKGROUND Apnea of prematurity (AOP) occurs frequently in preterm infants and a variable proportion of AOP can be induced by gastroesophageal reflux (GER). Conservative treatment, including dietary modifications, should be the first-line approach for both GER and GER-related apneas in this population. OBJECTIVES To evaluate the efficacy of a starch-thickened preterm formula (PF) in reducing the frequency of apneas related to GER. METHODS Preterm infants with AOP were studied by combined impedance and pH monitoring and polysomnography. The 6-hour study period included two feeds, one of a commercially available PF and one of the same formula thickened with amylopectin (TPF). GER indexes, apneas and GER-related apneas detected after TPF and PF feeds were compared by Wilcoxon signed-rank test. RESULTS 24 infants were studied. During 140 h of registration, 289 apneas (147 after TPF and 142 after PF; p = 0.876), and 861 GER episodes (400 after TPF and 461 after PF; p = 0.465) were recorded. No difference in the number of AOP was found between TPF and PF. A significant reduction in acid exposure was found after TPF; there was no influence on non-acid GER indexes. The frequency of GER-related apneas did not differ between TPF and PF. CONCLUSIONS A formula thickened with amylopectin did not reduce the number of AOP or GER-related apneas. It reduced acid GER features but had no effect on non-acid GER indexes. Future research should focus on exploring different conservative strategies to treat GER-related apneas in preterm infants.

Abstract
UNLABELLED The loop diuretics furosemide and bumetanide are commonly used in neonatal intensive care units (NICUs). Furosemide, because of its actions on the ubiquitous Na(+) -K(+) -2Cl(-) isoform cotransporter and its promotion of prostanoid production and release, also has non-diuretic effects on vascular smooth muscle, airways, the ductus arteriosus and theoretically the gastrointestinal tract. Loop diuretics also affect the central nervous system through modulation of the GABA-A chloride channel. CONCLUSION The loop diuretics have a variety of biological effects that are potentially harmful as well as beneficial. Care should be taken with the use of these agents because the range of their effects may be broader than the single action sought by the prescribing physician.

Abstract
Esophageal pathologies are complex and lend themselves to multivariable analysis before a definitive diagnosis can be considered. It is imperative that the clinician establish a methodology for selecting the appropriate technological assessment within scientific testing parameters to establish optimal clinicopathological presentation and determine best practice for patient care.

Abstract
Pharmacotherapy for gastroesophageal reflux (GER) in neonates, aimed at interfering with this physiologic process and potentially reducing the negative sequelae that providers often attribute to GER, consists primarily of drugs that increase the viscosity of feeds, reduce stomach acidity, or improve gut motility. Medications used to treat clinical signs thought to be from GER, such as apnea, bradycardia, or feeding intolerance, are among the most commonly prescribed medications in neonatal intensive care units in the United States, despite the lack of evidence of safety and efficacy in this population.
