The effect of sleep positional therapy on nocturnal gastroesophageal reflux measured by esophageal pH-impedance monitoring. Neurogastroenterol Motil 2023; 35:e14614. [PMID: 37246930 DOI: 10.1111/nmo.14614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 04/12/2023] [Accepted: 05/14/2023] [Indexed: 05/30/2023]
Abstract
BACKGROUND & AIMS The aim of the study was to evaluate the effect of an electronic positional therapy wearable device on nocturnal gastroesophageal reflux measured by pH-impedance reflux monitoring. METHODS We performed a single-center, prospective, interventional study in 30 patients with nocturnal reflux symptoms and a nocturnal esophageal acid exposure time (AET) ≥1.5% measured off acid-suppressive medication by ambulatory pH-impedance reflux monitoring. Patients were treated with an electronic positional therapy wearable device for 2 weeks. The device vibrates in the right lateral decubitus position so it conditions patients to avoid that sleep position. After 2 weeks treatment, the pH-impedance study was repeated. Primary outcome was the change in nocturnal AET. Secondary outcomes include change in number of reflux episodes and reflux symptoms. RESULTS Complete data were available for 27 patients (13 females, mean age 49.8 years). The median nocturnal AET decreased from 6.0% (IQR, 2.3-15.3) to 3.1% (0.1-10.8) after 2 weeks of treatment (p = 0.079). The number of reflux episodes was significantly reduced after 2 weeks of treatment (baseline: 8.0 (3.0-12.3) vs. end: 3.0 (1.0-8.0); p = 0.041). Treatment led to a statistically significant decrease in time spent in right lateral decubitus position (baseline: mean 36.9% ± 15.2% vs. end: 2.7% ± 8.2%; p = <0.001) and an increase in the left lateral decubitus position (baseline 29.2% ± 14.8% vs. end: 63.3% ± 21.9%; p = <0.001). Symptom improvement was reported by 70.4% of the patients. CONCLUSIONS Sleep positional therapy using an electronic wearable device promotes sleeping in the left lateral decubitus position and improves reflux parameters measured by pH-impedance reflux monitoring.

Abstract
Background The diagnostic criteria of infant regurgitation have been well elucidated in the Rome IV criteria and pediatricians have been informed of them. However, as a functional disorder, infant regurgitation is susceptible to misdiagnosis and inappropriate management.
Objective To assess pediatricians’ diagnostic knowledge of and therapeutic approach to infant regurgitation.
Methods We conducted a cross-sectional, analytical study using a questionnaire based on Rome IV criteria for infant regurgitation diagnosis and standardized guidelines for management. The questionnaire was face-level validated by an expert and tested for both reliability and correlation using 30 test respondents. The questionnaire was then distributed electronically to 131 randomized pediatricians, who were members of the Indonesian Pediatric Society DKI Jakarta branch and graduated from pediatric residency within year 2005-2019.
Results Sixty-seven (51%) pediatricians reported applying the Rome IV criteria in daily clinical practice. Pediatricians who used Rome IV as their source of knowledge achieved mean and median diagnostic knowledge scores of 14.87 (SD 2.540) and 16 (range 8–20), respectively, with no significant correlation between the usage of ROME IV and the pediatricians’ diagnostic understanding (P=0.110), and mean and median therapeutic knowledge scores of 9.10 (SD 2.264) and 10 (range 4–12), respectively, with no significant correlation between the usage of ROME IV and the pediatricians’ therapeutic approach (P=0.486). Pediatricians’ diagnostic knowledge and therapeutic approach were not significantly different with regards to their practice experience, specialist institution, workplaces, and source of information.
Conclusion The majority of pediatricians surveyed have good diagnostic and therapeutic knowledge scores with regards to handling of Rome IV infant regurgitation.

Abstract
BACKGROUND Total gastric retention (TGR) from gastric emptying scintigraphy (GES) is used for diagnosing gastroparesis (Gp), but correlates poorly with patients' symptoms. Regional intragastric meal distribution (RIMD) can also be assessed from GES. This study classified patients' meal distribution as proximal or distal to relate RIMD to symptoms of Gp. METHODS GES studies in patients (n = 193) and control subjects (n = 21) were selected for RIMD analysis. Patients completed Patient Assessment of Upper Gastrointestinal Symptoms (PAGI-SYM) for symptom severity before GES. TGR was analyzed using % TGR, and RIMD used a proximal/distal gastric count ratio (PDCR). Results were classified as proximal or distal RIMD at 0, 1, 2, and 4 h postprandially based on their PDCR being above or below the median value of the patients. RESULTS Patients with delayed GE and immediate post-meal ingestion distal distribution had more severe early satiety and regurgitation. Distal distribution at 1 h had more severe early satiety and loss of appetite compared to proximal distribution. Patients with delayed GE and proximal distribution at 4 h had more severe nausea, retching, and vomiting compared to 4 h distal distribution. Severely delayed 4 h proximal distribution had more nausea than severely delayed 4 h distal distribution. CONCLUSIONS Increased early distal IMD in patients with delayed GE was associated with regurgitation and early satiety whereas increased late proximal IMD was associated with nausea, retching, and vomiting. Differentiating proximal from distal meal distribution patterns helps to relate symptoms to gastric dysfunction and may be helpful for directing therapy.

Abstract
INTRODUCTION The aim of this study was to investigate the effect of spontaneous sleep positions on the occurrence of nocturnal gastroesophageal reflux. METHODS In patients referred for ambulatory pH-impedance reflux monitoring, the concurrent sleep position was measured using a sleep position measurement device (measuring left, right, supine, and prone positions). RESULTS Fifty-seven patients were included. We observed a significantly shorter acid exposure time in the left (median 0.0%, P25-P75, 0.0%-3.0%), compared with the right lateral position (median 1.2%, 0.0%-7.5%, P = 0.022) and the supine position (median 0.6%, 0.00%-8.3%, P = 0.022). The esophageal acid clearance time was significantly shorter in the left lateral decubitus position (median 35 seconds, 16-115 seconds), compared with the supine (median 76 seconds, 22-257 seconds, P = 0.030) and right lateral positions (median 90 seconds, 26-250 seconds, P = 0.002). DISCUSSION The left lateral decubitus position is associated with significantly shorter nocturnal esophageal acid exposure time and faster esophageal acid clearance compared with the supine and right lateral decubitus positions (see visual abstract).

Abstract
Of the nearly 3.8 million infants born in the United States in 2018, 8.3% had low birth weight (ie, weight <2500 g) and 10% were born preterm (ie, gestational age of <37 weeks). Ten to fifteen percent of infants (approximately 500 000 annually), including low birth weight and preterm infants and others with congenital anomalies, perinatally acquired infections, and other diseases, require admission to a NICU. Every year, approximately 3600 infants in the United States die of sudden unexpected infant death (SUID), including sudden infant death syndrome (SIDS), unknown and undetermined causes, and accidental suffocation and strangulation in an unsafe sleep environment. Preterm and low birth weight infants are 2 to 3 times more likely than healthy term infants to die suddenly and unexpectedly. Thus, it is important that health care professionals prepare families to maintain their infant in a safe home sleep environment as per recommendations of the American Academy of Pediatrics. Medical needs of the NICU infant often require practices such as nonsupine positioning, which should be transitioned as soon as medically possible and well before hospital discharge to sleep practices that are safe and appropriate for the home environment. This clinical report outlines the establishment of appropriate NICU protocols for the timely transition of these infants to a safe home sleep environment. The rationale for these recommendations is discussed in the accompanying technical report "Transition to a Safe Home Sleep Environment for the NICU Patient," included in this issue of Pediatrics.

Abstract
Of the nearly 3.8 million infants born in the United States in 2018, 8.3% had low birth weight (<2500 g [5.5 lb]) and 10% were born preterm (gestational age of <37 completed weeks). Many of these infants and others with congenital anomalies, perinatally acquired infections, and other disease require admission to a NICU. In the past decade, admission rates to NICUs have been increasing; it is estimated that between 10% and 15% of infants will spend time in a NICU, representing approximately 500 000 neonates annually. Approximately 3600 infants die annually in the United States from sleep-related deaths, including sudden infant death syndrome International Classification of Diseases, 10th Revision (R95), ill-defined deaths (R99), and accidental suffocation and strangulation in bed (W75). Preterm and low birth weight infants are particularly vulnerable, with an incidence of death 2 to 3 times greater than healthy term infants. Thus, it is important for health care professionals to prepare families to maintain their infant in a safe sleep environment, as per the recommendations of the American Academy of Pediatrics. However, infants in the NICU setting commonly require care that is inconsistent with infant sleep safety recommendations. The conflicting needs of the NICU infant with the necessity to provide a safe sleep environment before hospital discharge can create confusion for providers and distress for families. This technical report is intended to assist in the establishment of appropriate NICU protocols to achieve a consistent approach to transitioning NICU infants to a safe sleep environment as soon as medically possible, well before hospital discharge.

Role of feeding strategy bundle with acid-suppressive therapy in infants with esophageal acid reflux exposure: a randomized controlled trial. Pediatr Res 2021; 89:645-652. [PMID: 32380509 PMCID: PMC7647955 DOI: 10.1038/s41390-020-0932-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Revised: 02/24/2020] [Accepted: 04/23/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVE To test the hypothesis that a feeding bundle concurrent with acid suppression is superior to acid suppression alone in improving gastroesophageal reflux disease (GERD) attributed-symptom scores and feeding outcomes in neonatal ICU infants. METHODS Infants (N = 76) between 34 and 60 weeks' postmenstrual age with acid reflux index > 3% were randomly allocated to study (acid-suppressive therapy + feeding bundle) or conventional (acid-suppressive therapy only) arms for 4 weeks. Feeding bundle included: total fluid volume < 140 mL/kg/day, fed over 30 min in right lateral position, and supine postprandial position. Primary outcome was independent oral feeding and/or ≥6-point decrease in symptom score (I-GERQ-R). Secondary outcomes included growth (weight, length, head circumference), length of hospital stay (LOHS, days), airway (oxygen at discharge), and developmental (Bayley scores) milestones. RESULTS Of 688 screened: 76 infants were randomized and used for the primary outcome as intent-to-treat, and secondary outcomes analyzed for 72 infants (N = 35 conventional, N = 37 study). For study vs. conventional groups, respectively: (a) 33% (95% CI, 19-49%) vs. 44% (95% CI, 28-62%), P = 0.28 achieved primary outcome success, and (b) secondary outcomes did not significantly differ (P > 0.05). CONCLUSIONS Feeding strategy modifications concurrent with acid suppression are not superior to PPI alone in improving GERD symptoms or discharge feeding, short-term and long-term outcomes. IMPACT Conservative feeding therapies are thought to modify GERD symptoms and its consequences. However, in this randomized controlled trial in convalescing neonatal ICU infants with GERD symptoms, when controlling for preterm or full-term birth and severity of esophageal acid reflux index, the effectiveness of acid suppression plus a feeding modification bundle (volume restriction, intra- and postprandial body positions, and prolonged feeding periods) vs. acid suppression alone, administered over a 4-week period was not superior in improving symptom scores or feeding outcomes. Restrictive feeding strategies are of no impact in modifying GERD symptoms or clinically meaningful outcomes. Further studies are needed to define true GERD and to identify effective therapies in modifying pathophysiology and outcomes. The improvement in symptoms and feeding outcomes over time irrespective of feeding modifications may suggest a maturational effect. This study justifies the use of placebo-controlled randomized clinical trial among NICU infants with objectively defined GERD.

Abstract
Introduction: Gastro-esophageal reflux disease (GERD) in infants is worldwide diagnosed with increasing frequency, resulting in an increasing number of infants exposed to treatment. In this review, we focus on the safety of therapeutic options. Areas covered: English articles were searched from 1990 until May 2020 in PubMed and Google Scholar. Evidence suggests that non-pharmacological treatment is often effective and safe. Guidelines restrict pharmacological treatment to acid-suppressive medication, which is associated with adverse effects, often related to gastro-intestinal dysbiosis and consequences of the latter. Aluminum-free alginates have some efficacy and are not associated with relevant adverse effects. Especially in infants, GERD is often nonacid related. Prokinetics are not recommended because of lack of efficacy and numerous adverse effects. Expert opinion: Pediatric trials are underpowered regarding adverse effects. The number of infants exposed to anti-secretory agents is increasing worldwide, often without indication. Informing healthcare providers about adverse effects of acid-secretory medication may contribute to a more rational use. Acid inhibiting agents such as alginates are a drug class associated with limited efficacy and devoid of serious adverse effects. Regarding prokinetics, the risk of adverse effects outweighs the benefit. Reassurance of parents and nutritional management of GERD in infants is effective and safe.

Abstract
INTRODUCTION Aims were to test hypothesis that esophageal provocation-induced reflexes are superior with acid suppression plus feeding modifications vs acid suppression alone among infants treated for gastroesophageal reflux disease (GERD). METHODS Infants (N = 49, 41.3 ± 2.6 of postmenstrual age) with acid reflux index >3% underwent longitudinal motility testing (weeks 0 and 5) with graded midesophageal provocation to test randomly allocated therapies (4 weeks' proton pump inhibitor [PPI] ± feeding modifications) on sensory-motor aerodigestive reflexes. Feeding modification included restricted fluid volume <140 mL/kg per day, fed over 30 minutes in right lateral position and supine postprandial position. Primary motility outcome was frequency-occurrence of peristaltic reflex. Secondary outcomes included upper esophageal sphincter contractile reflex, lower esophageal sphincter (LES) relaxation reflex, respiratory change, and symptom characteristics. RESULTS Treatment groups did not differ for primary outcome (odds ratio = 0.8, 95% confidence interval 0.4-1.6, P = 0.99) or secondary outcomes (all P > 0.05). For both treatment groups at follow-up, distal esophageal contraction and LES tone decreased, and LES relaxation reflex occurrence is less frequent (all P < 0.05). In a subgroup analysis, comparing infants with PPI washout (N = 40) vs with continued (N = 9) PPI therapy, no differences were noted for aerodigestive reflex response frequency-occurrence (all P > 0.05). DISCUSSION In infants with GERD, feeding modification with acid suppression is not superior to acid suppression alone in modifying aerodigestive reflexes (frequency, sensation, or magnitude). Contiguous areas targeted by GER, i.e., LES and distal esophageal functions, worsened at follow-up for both groups despite PPI therapy. Maturation is likely the key factor for GERD resolution in infants, justifying the use of placebo in clinical trials for objectively determined GERD.

Abstract
AIM Postural measures are frequently recommended for gastroesophageal reflux (GER) symptoms, despite limited evidence. This was the first study to assess the impact of upright and recumbent body positions on GER episodes in children and adolescents, not just infants. METHODS We retrospectively assessed the pH-impedance parameters of paediatric patients referred for possible GER-related symptoms to two hospitals in Naples and Rome, Italy, from September 2016 to September 2018. Data were separately obtained for the time that the patients spent in upright and recumbent positions. RESULTS Data from 187 patients under the age of 18 were collected, at a mean age of just over seven years. We found that the acid exposure time was stable irrespective of changes in body position (P > .05). The mean number of reflux episodes per hour was 2.99 during the upright position and 1.21 during the recumbent position (P < .05), and the mean oesophageal acid clearance time was 44.4 and 93.4 seconds, respectively (P < .05). CONCLUSION Most paediatric patients experienced reflux in the upright rather than recumbent position, probably as a result of frequent transient lower oesophageal sphincter relaxations while they were awake. In particular, our findings provide new insights into postural measures for reflux in children and adolescents.

Abstract
Preterm infants frequently present with respiratory insufficiency requiring respiratory assistance. Invasive mechanical ventilation has been associated with several short and long term complications. Therefore, the practice of early use of non-invasive ventilation has been adopted. Nasal CPAP proved efficacy as an initial therapy for preterm infants. Non-invasive positive pressure ventilation is an alternative used to mitigate CPAP failure in infants with apnea or increased work of breathing. High flow nasal cannula gained popularity primarily due to the ease of its use, despite multiple prominent trials that demonstrated its inferiority. Bi-level positive airway pressure and neurally adjusted non-invasive ventilatory are used in infants with apnea and increased work of breathing. The effectiveness of non invasive ventilation tools can be augmented by having a proper protocol for initiation, weaning, skin care, positioning, and developmental care during their application.

Abstract
Gastroesophageal reflux is the involuntary retrograde passage of gastric contents into the esophagus with or without regurgitation and is considered a normal physiologic process, occurring daily in greater than one-third of all infants. Gastroesophageal reflux disease (GERD) is pathologic reflux associated with poor weight gain, irritability, dysphagia and often requires evaluation and treatment. No gold-standard testing for GERD exists. Measurements made by pH probe or multichannel intraesophageal impedance may provide insight into the quantity and character of reflux. Those events do not correlate well with clinical symptoms. Most cases of GERD can be treated conservatively with alterations in the infant's environment and/or feeding pattern. Proton pump inhibitors remain the mainstay for pharmacotherapy of GERD, although these have been associated with increased rates of infection, especially in the preterm population. Neonatal GERD remains a difficult entity to define and manage, and additional studies to aid in the clinical diagnosis and management are needed. [Pediatr Ann. 2020;49(2):e77-e81.].

Abstract
Gastro-oesophageal reflux (GOR) in infancy is common, physiological and self-limiting; it is distinguished from gastro-oesophageal reflux disease (GORD) by the presence of organic complications and/or troublesome symptomatology. GORD is more common in infants with certain comorbidities, including history of prematurity, neurological impairment, repaired oesophageal atresia, repaired diaphragmatic hernia, and cystic fibrosis. The diagnosis of GORD in infants relies almost exclusively on clinical history and examination findings; the role of invasive testing and empirical trials of therapy remains unclear. The assessment of infants with vomiting and regurgitation should seek out red flags and not be attributed to GOR or GORD without considered evaluation. Investigations should be considered to exclude other pathology in infants referred with suspected GORD, and occasionally to confirm the diagnosis. Management of GORD should follow a step-wise approach that uses non-pharmacological options where possible and pharmacological interventions only where necessary.

Abstract
Multichannel intraluminal impedance pH (MII-pH) monitoring currently represents the gold standard diagnostic technique for the detection of gastro-esophageal reflux (GER), since it allows to quantify and characterize all reflux events and their possible relation with symptoms. Over the last ten years, thanks to its strengths and along with the publication of several clinical studies, its worldwide use has gradually increased, particularly in infants and children. Nevertheless, factors such as the limited pediatric reference values and limited therapeutic options still weaken its current clinical impact. Through an up-to-date review of the available scientific evidence, our aim was to produce a position paper on behalf of the working group on neurogastroenterology and acid-related disorders of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) on MII-pH monitoring technique, indications and interpretation in pediatric age, in order to standardise its use and to help clinicians in the diagnostic approach to children with GER symptoms.

Abstract
Gastroesophageal reflux (GER) is the retrograde movement of gastric (and sometimes duodenal) contents into the esophagus. While the majority of GER is physiologic, for patients, it can be associated with symptoms. While some symptoms are merely bothersome (crying), others can be life threatening (cough, gagging, choking). The main driver of GER in infants is the frequent feedings that produce increased intra-abdominal pressure, which is known to trigger transient relaxations of the lower esophageal sphincter. The recent 2018 clinical practice guidelines reported by the North American and European Societies for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN/ESPGHAN) have recommended non-pharmacologic management initially with subsequent consideration of brief trials with acid suppressants. The main target for these acid suppressants is the gastric parietal cells. Our review of the literature has revealed a paucity of data regarding the use of histamine-2 receptor antagonists and proton pump inhibitors in infants. Despite the absence of well-controlled clinical studies, the prescription rate of these medications has increased internationally. Risks to patients of all ages have become increasingly recognized, with new associations being reported all too often. Here we report our review of all pharmacologic modalities as well as some non-surgical options.

Abstract
Objective: To evaluate the effect of right lateral positioning in comparison with supine positioning on tracheal aspirate pepsin levels as a marker of aspiration of gastric contents in ventilated preterm neonates. Study design: This randomized controlled trial was conducted on 60 ventilated preterm neonates <35 weeks; 30 neonates were nursed in right lateral position for 6 hours while the other 30 neonates were nursed in supine position for 6 hours. Tracheal aspirate sample was obtained from each neonate in both the groups just after the end of 6 hours and pepsin level was measured. Results: Neonates in right lateral position group had significantly lower tracheal pepsin level than neonates in supine position group (6 ng/ml) interquartile range [IQR] (3-20) versus 15 ng/ml [IQR] (5.5-90) (p = .024). There is positive correlation between tracheal aspirate pepsin level and fraction of inspired oxygen (FiO2) needed during the intervention (r = 0.383, p = .040). There is no correlation between tracheal pepsin level and gestational age, birth weight, or duration of mechanical ventilation and other ventilatory settings. Conclusion: Nursing ventilated premature infants in right lateral position is associated with decreased aspiration of gastric contents.

Abstract
This document serves as an update of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) 2009 clinical guidelines for the diagnosis and management of gastroesophageal reflux disease (GERD) in infants and children and is intended to be applied in daily practice and as a basis for clinical trials. Eight clinical questions addressing diagnostic, therapeutic and prognostic topics were formulated. A systematic literature search was performed from October 1, 2008 (if the question was addressed by 2009 guidelines) or from inception to June 1, 2015 using Embase, MEDLINE, the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Clinical Trials. The approach of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) was applied to define and prioritize outcomes. For therapeutic questions, the quality of evidence was also assessed using GRADE. Grading the quality of evidence for other questions was performed according to the Quality Assessment of Studies of Diagnostic Accuracy (QUADAS) and Quality in Prognostic Studies (QUIPS) tools. During a 3-day consensus meeting, all recommendations were discussed and finalized. In cases where no randomized controlled trials (RCT; therapeutic questions) or diagnostic accuracy studies were available to support the recommendations, expert opinion was used. The group members voted on each recommendation, using the nominal voting technique. With this approach, recommendations regarding evaluation and management of infants and children with GERD to standardize and improve quality of care were formulated. Additionally, 2 algorithms were developed, 1 for infants <12 months of age and the other for older infants and children.

Abstract
BACKGROUND Body position affects the gastric emptying rate and hence the amount of gastric residue. OBJECTIVE This study aims to analyze the effect of the post-feeding position of preterm infants on gastric residue. MATERIALS AND METHODS This experimental study was conducted in the neonatal intensive care unit (NICU) of a university hospital (İnönü University Turgut Özal Medical Center) in Eastern Turkey. The study included 40 preterm infants weighing less than 2,000 g, who were fed orogastrically. The preterm infants were sequentially placed in four positions and were fed before each change of position. The infants were sequentially placed in the right lateral, left lateral, supine, and prone positions; their gastric residues were measured with a nasogastric tube. The gastric residue was recorded in percentages at 30, 60, 120, and 180 minutes. Ethical principles were applied in all phases of the study. RESULTS The lowest mean gastric residue level was observed in the right lateral position at 30 minutes (58.16 ± 12.71%) and 60 minutes (33.97 ± 15.00%). The prone position showed the lowest mean gastric residue level (1.74 ± 1.08%), followed by the right lateral (3.06 ± 1.97%), supine (3.53 ± 2.18%), and left lateral position (5.14 ± 1.85%) at 120 minutes. The final measurements were taken at 180 minutes with the right lateral position showing the lowest mean gastric residue level (0.38 ± 0.34%). CONCLUSION The premature infants had similar lower levels of gastric residue in the right lateral and prone positions and higher levels of gastric residue in left lateral and supine positions. The gastric emptying rate was found to be highest in the right lateral position at 30, 60, and 180 minutes and in the prone position at 120 minutes.

Abstract
OBJECTIVES Multichannel intraluminal impedance studies (MII-pH) have become the criterion standard for the diagnosis of gastroesophageal reflux (GER). Several clinical signs and symptoms that are attributed to GER during infancy may not be related to true reflux. Our objective was to correlate the observed reflux-like behaviors to reflux events on MII-pH studies. METHODS This is a retrospective study on infants being evaluated for GER with MII. During the MII-pH study, the infants were observed for clinical behaviors. Symptom Index (SI), symptom sensitivity index (SSI), and symptom association probability were used to correlate symptoms with reflux events. RESULTS Of 58 infants (40 preterm, 18 term) included in the study, only 6 infants (10%) had an abnormal MII-pH study. Irritability (32 infants), bradycardia (20), and desaturation (18) were the common signs and symptoms. A total of 2142 (755 acidic and 1386 nonacidic) reflux episodes and 953 clinical reflux behaviors were recorded. The incidence and pattern of GER was similar in preterm and term infants. There was no significant difference in GER episodes and acid exposure in preterm infants fed orally or via nasogastric tube. The symptom association probability was abnormal in only 6 (19%), 1 (5%), and 5 (28%) infants with irritability, bradycardia, and desaturation, respectively. CONCLUSIONS The prevalence of GER as detected by MII-pH was low (10%) in symptomatic preterm and term infants. The incidence and pattern of GER was similar in preterm and term infants. The majority of suspected clinical reflux behaviors did not correlate with reflux events.

Abstract
BACKGROUND The use of noninvasive ventilation is a constantly evolving treatment option for respiratory disease in the premature infant. The goals of these noninvasive ventilation techniques are to improve gas exchange in the premature infant's lungs and to minimize the need for intubation and invasive mechanical ventilation. PURPOSE The goals of this article are to consider various uses of nasal interfaces, discuss skin care and developmental positioning concerns faced by the bedside nurse, and discuss the medical management aimed to reduce morbidity and mortality. This article explores the nursing role, the advances in medical strategies for noninvasive ventilation, and the team approach to noninvasive ventilation use in this population. SEARCH STRATEGY Search strategy included a literature review on medical databases, such as EBSCOhost, CINAHL, PubMed, and NeoReviews. FINDINGS Innovative products, nursing research on developmental positioning and skin care, and advanced medical management have led to better and safer outcomes for premature infants requiring noninvasive ventilation. IMPLICATIONS FOR PRACTICE The medical focus of avoiding long-term mechanical ventilation would not be possible without the technology to provide noninvasive ventilation to these premature infants and the watchful eye of the nurse in terms of careful positioning, preventing skin breakdown and facial scarring, and a proper seal to maximize ventilation accuracy. IMPLICATIONS FOR RESEARCH This article encourages nursing-based research to quantify some of the knowledge about skin care and positioning as well as research into most appropriate uses for noninvasive ventilation devices.

Abstract
OBJECTIVES Gastroesophageal reflux and aspiration can occur in premature infants who are supported with mechanical ventilation. The relation between physical positioning and gastric aspiration in ventilated infants has not been studied. Pepsin measured in tracheal aspirate (TA) emerged as a specific marker for aspiration. The objective of our study was to assess pepsin in TA of ventilated infants at 2 different positions: supine and right lateral. METHODS We conducted a randomized controlled trial on premature infants who were enterally fed and supported with mechanical ventilation. Patients were randomized into intervention and control groups. In the intervention group, infants were placed supine for 6 hours before a sample of TA was obtained. A second sample was collected 6 hours later while lying in the right lateral position. In the control group, the 2 samples of TA were obtained while infants remained in the supine position during the entire study time. Pepsin in TA was measured while blinded to the group assignment. RESULTS A total of 34 patients were enrolled and randomized to intervention (n = 17) and control (n = 17) groups. Gestational age was 32.7 ± 2.7 weeks, and birth weight was 1617 ± 526 g; both groups had similar demographic and clinical characteristics. Pepsin concentration did not differ between groups at baseline. In the intervention group, pepsin concentration significantly declined from 13 ng/mL (interquartile range [IQR] 11.9-38.7) to 10 ng/mL (IQR 7-12; P < 0.001), whereas it did not change in the control group (P = 0.42). CONCLUSIONS The right lateral positioning is associated with decreased TA pepsin. The implications of the present study on hospital practice and clinical outcomes need further investigations.

Abstract
Gastroesophageal reflux and gastroesophageal reflux disease symptoms are common challenges for very low-birth-weight infants (<1500 g). These symptoms frequently result in feeding difficulties and family stress. Management of symptoms across healthcare disciplines may not be based on current evidence, and inconsistency can result in confusion for families and delayed interventions. The feeding relationship between infant and caregivers may be impaired when symptoms are persistent and poorly managed. An algorithm for managing gastroesophageal reflux-like symptoms in very low-birth-weight infants (from hospital discharge to 12 months corrected age) was developed through the formation of a multidisciplinary community of practice and critical appraisal of the literature. A case study demonstrates how the algorithm results in a consistent approach for identifying symptoms, applying appropriate management strategies, and facilitating appropriate timing of medical consultation. Application to managing gastroesophageal reflux symptoms in the neonatal intensive care unit will be briefly addressed.

Abstract
OBJECTIVE Proton-pump inhibitors (PPIs) reduce acid gastroesophageal reflux (GER) and esophageal acid exposure in infants; however, they do not reduce total GER or symptoms attributed to GER. Reflux is reduced in the left lateral position (LLP). We hypothesize that the effect of LLP in combination with acid suppression is most effective in reducing GER symptoms in infants. METHODS In this prospective sham-controlled trial, infants (0-6 months) with symptoms suggestive of gastroesophageal reflux disease were studied using 8-hour pH-impedance, cardiorespiratory and video monitoring, direct nurse observation, and a validated questionnaire. Infants demonstrating a positive GER symptom association were randomized to 1 of 4 groups; PPI + LLP, PPI + head of cot elevation (HE), antacid (AA) + LLP, or AA + HE. HE and AA were considered "sham" therapies. After 2 weeks the 8-hour studies were repeated on-therapy. RESULTS Fifty-one patients were included (aged 13.6 [2-26] weeks). PPI + LLP was most effective in reducing GER episodes (69 [13] to 46 [10], P < 0.001) and esophageal acid exposure (median [interquartile range] 8.9% [3.1%-18.1%] to 1.1% [0%-4.4%], P = 0.02). No treatment group showed improvement in crying/irritability, although vomiting was reduced in AA + LLP (from 7 [2] to 2 [0] episodes P = 0.042). LLP compared with HE produced greater reduction in total GER (-21 [4] vs -10 [4], P = 0.056), regardless of acid-suppressive therapy. Acid exposure was reduced on PPI compared with AA (-6.8 [2.1] vs -0.9 [1.4]%, pH < 4, P = 0.043) regardless of positional intervention. A post-hoc analysis using automated analysis software revealed a significant reduction in crying symptoms in the PPI + LLP group (99 [65-103] to 62 [32-96] episodes, P = 0.018). CONCLUSIONS "Symptomatic gastroesophageal reflux disease" implies disease causation for distressing infant symptoms. In infants with symptoms attributed to GER, LLP produced a significant reduction in total GER, but did not result in a significant improvement in symptoms other than vomiting; however, automated analysis appeared to identify infants with GER-associated crying symptoms who responded to positioning therapy. This is an important new insight for future research.

Abstract
OBJECTIVES The aim of the present study was to determine whether serial gastric volumes and intragastric curding are repeatable within individual preterm infants when given sequential feeds of the same volume and composition. Infant and feeding characteristics that may influence differences in measured gastric volumes, echogenicity, and intragastric curding were also explored. METHODS Ultrasound images were used to calculate gastric volumes and to rate echogenicity and intragastric curding for 20 infants. A total of 29 paired feeds of the same volume and composition were monitored prefeed and postfeed and at 30-minute intervals thereafter. Statistical comparisons of paired gastric volume measurements and agreement between echogenicity and curding ratings were made for each time point. Analyses of factors that influence discrepancies between volume measurements and between curding ratings were performed. RESULTS Paired gastric volume measurements were repeatable (intraclass correlation coefficient [ICC] = 0.971, 0.938 < ICC < 0.987). Most (75%) discrepancies were <2 mL and increased over time, although volume differences were small. Overall moderate levels of consistency were observed for ratings of echogenicity (κ = 0.44), and curd presence (κ ≤ 0.65), density (κ = 0.41), and volume (κ = 0.47). Gastric emptying during feed delivery is influenced with infant positioning, fortification of breast milk, and feeding frequency. CONCLUSIONS For preterm infants serial gastric volumes are repeatable and ratings of intragastric echogenicity and curding are moderately consistent when fed milk of the same volume and composition. Ultrasound has the potential to further explore factors that influence gastric emptying in the preterm infant.

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.

Extensively hydrolyzed protein formula reduces acid gastro-esophageal reflux in symptomatic preterm infants. Early Hum Dev 2013; 89:453-5.

Abstract
BACKGROUND Gastro-esophageal reflux (GER) is diagnosed frequently in preterm infants. Pharmacological treatment of GER has some potential side effects. Conservative treatment of GER should be the first-line approach and should include body positioning and diet modifications. Formula-fed preterm infants experience frequently symptoms of feeding intolerance. Hydrolyzed protein formula (HPF) is often used in these infants due to their effects on gastrointestinal motility. AIMS To investigate the role of an extensively HPF (eHPF) on GER indexes in formula-fed preterm infants with symptoms of both GER and feeding intolerance. STUDY DESIGN Randomized crossover trial. SUBJECTS Preterm infants (gestational age ≤33 weeks) with symptoms of feeding intolerance (large gastric residuals, abdominal distension and constipation) and GER (frequent regurgitations and/or postprandial desaturations). OUTCOME MEASURES GER indexes detected by 24-h combined multichannel intraluminal impedance and pH monitoring. GER indexes detected after 4 feeds of an eHPF were compared to those detected after 4 feeds of a standard preterm formula (SPF) by Wilcoxon signed ranks test. A p<0.05 was considered statistically significant. RESULTS eHPF significantly reduced the number of GERs detected by pH monitoring (p=0.036) and also the reflux index (p=0.044) compared to SPF. No differences in impedance bolus exposure indexes nor in GER height were detected. CONCLUSIONS The use of an eHPF should be evaluated for reducing esophageal acid exposure in preterm infants with feeding intolerance and symptoms of GER. Future research should focus on the evaluation of an eHPF adequate for preterm infants in improving clinical symptoms of GER.

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
OBJECTIVE To compare breathing patterns and lung function in the supine, lateral, and prone positions in oxygen-dependent preterm infants. STUDY DESIGN Respiratory function in preterm infants receiving nasal continous positive airway pressure therapy for mild respiratory failure was evaluated by respiratory inductive plethysmography. Infants were randomized to supine, left lateral, and prone positions for 3 hours. A nest provided a semiflexed posture for the infants placed in the left lateral position, similar to the in utero position. Tidal volume (Vt), phase angle between abdominal and thoracic movements, rib cage contribution to Vt, and dynamic elevation of end-expiratory lung volume were measured. RESULTS Fraction of inspired O2 was similar in the 3 positions for 19 infants (mean gestational age, 27±2 weeks; mean birth weight, 950±150 g; mean postnatal age, 17±5 days). However, arterial O2 saturation and Vt were higher in the left lateral and prone positions than in the supine position (P<.05). The phase angle between abdominal and thoracic movements was lower and rib cage contribution to Vt was higher in the left lateral and prone positions than in the supine position (P<.05). Dynamic elevation of end-expiratory lung volume was greater in the supine position than in the left lateral and prone positions (P<.05). CONCLUSION In oxygen-dependent preterm infants, both the left lateral and prone positions improve lung function by optimizing breathing strategy. In the neonatal intensive care unit, the left lateral position can be used as an alternative to the prone position for mild respiratory failure.

Abstract
BACKGROUND Posture has been shown to influence the number of transient lower esophageal sphincter relaxation (TLESRs) and gastroesophageal reflux (GER), however, the physiology explaining the influence of right lateral position (RLP), and left lateral position (LLP) is not clear. The aim of this study was to determine the influence of RLP and LLP on TLESRs and GERD after a meal in GER disease (GERD) patients and healthy controls (HC) while monitoring gastric distension and emptying. METHODS Ten GERD patients and 10 HC were studied for 90 min (30 min test meal infusion, 30 min postprandial in either RLP or LLP (randomly assigned) and 30 min in alternate position). The study was repeated on a separate day in reverse position order. TLESRs, GER, and gastric emptying rate were recorded using manometry, multichannel intraluminal impedance, and (13) C-octanoate breath tests. Gastric distension was visualized by five serial gastric volume scintigraphy scans during the first 30 min. KEY RESULTS Gastroesophageal reflux, (GER) disease patients had increased numbers of TLESRs in RLP compared to LLP in the first postprandial hour [5 (4-14) and 4.5 (2-6), respectively, P = 0.046] whereas the number of TLESRs was not different in RLP and LLP [4 (2-4) and 4 (3-6), respectively, P = 0.7] in HC. Numbers of GER increased similar to TLESRs in GERD patients. In GERD patients, gastric emptying reached peak (13)CO(2) excretion faster and proximal gastric distension was more pronounced. CONCLUSIONS & INFERENCES In GERD patients, TLESRs, GER, distension of proximal stomach, and gastric emptying are increased in RLP compared to LLP. This effect is not seen in HC.

Abstract
OBJECTIVE To study the relationship between pepsinogen/pepsin in a mouth swab and clinical gastroesophageal reflux (GER) in preterm infants. METHODS Preterm infants (birth weight ≤ 2000 g) on full enteral feeds were enrolled. Mouth swabs from cheek and below the tongue were collected one, two and three hours after feeding. An enzymatic assay with substrate fluorescein isothiocyanate-casein was used to detect pepsin A and C activities with further confirmation by western blot. Blinded investigators reviewed the infant's medical record to clinically diagnose GER. RESULTS A total of 101 premature infants were enrolled. Pepsinogen/pepsin was detected in 45/101 (44.5%) infants in at least one sample. A clinical diagnosis of GER was made in 36/101 (35.6%) infants. Mouth swabs were positive in 26/36 (72%) infants with clinical GER and only 19/65 (29%) infants without GER (p < 0.001). Similarly, the levels of pepsinogen/pepsin A and C were higher in the mouth swabs of infants with clinical GER. CONCLUSION The detection of pepsinogen/pepsin in a mouth swab correlates with clinical GER in premature infants.

Abstract
Gastroesophageal reflux (GER) is defined as the involuntary retrograde passage of gastric contents into the esophagus with or without regurgitation or vomiting. It is a frequently experienced physiologic condition occurring several times a day, mostly postprandial and causes no symptoms. These infants are also called 'happy spitters'. GER disease (GERD) occurs when reflux of the gastric contents causes symptoms that affect the quality of life or pathologic complications, such as failure to thrive, feeding or sleeping problems, chronic respiratory disorders, esophagitis, hematemesis, apnea, and apparent life-threatening events. About 70-85 % of infants have regurgitation within the first 2 months of life, and this resolves without intervention in 95 % of infants by 1 year of age. The predominant mechanism causing GERD is transient lower esophageal sphincter (LES) relaxation, which is defined as an abrupt decrease in LES pressure to the level of intragastric pressure, unrelated to swallowing and of relatively longer duration than the relaxation triggered by a swallow. Regurgitation and vomiting are the most common symptoms of infant reflux. A thorough history and physical examination with attention to warning signals suggesting other causes is generally sufficient to establish a clinical diagnosis of uncomplicated infant GER. Choking, gagging, coughing with feedings or significant irritability can be warning signs for GERD or other diagnoses. If there is forceful vomiting, laboratory and radiographic investigation (upper gastrointestinal series) are warranted to exclude other causes of vomiting. Irritability coupled with back arching in infants is thought to be a non-verbal equivalent of heartburn in older children. Other causes of irritability, including cow's milk protein allergy, neurologic disorders, constipation and infection, should be ruled out. The presentation of cow's milk protein allergy overlaps with GERD, and both conditions may co-exist in 42-58 % of infants. In these infants, symptoms decrease significantly within 2-4 weeks after elimination of cow's milk protein from the diet. For non-complicated reflux, no intervention is required for most infants. Effective parental reassurance and education regarding regurgitation and lifestyle changes are usually sufficient to manage infant reflux. Sandifer syndrome, apnea and apparent life-threatening events are the extraesophageal manifestations of GERD in infants. Pharmacotherapeutic agents used to treat GERD encompass antisecretory agents, antacids, surface barrier agents and prokinetics. Currently, North American Society for Pediatric Gasroenterology, Hepatology and Nutrition (NASPGHAN) and European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) practice guidelines concluded that there is insufficient evidence to justify the routine use of prokinetic agents. Esomeprazole (Nexium) is now approved in the US for short-term treatment of GERD with erosive esophagitis in infants aged from 1 to 12 months. Although Nissen fundoplication is now well established as a treatment option in selected cases of GERD in children, its role in neonates and young infants is unclear and is only reserved for selective infants who did not respond to medical therapy and have life-threatening complications of GERD.

Abstract
Gastroesophageal reflux (GER) is very common in children due to immaturity of the antireflux barrier. In critically ill patients there is also a high incidence due to a partial or complete loss of pressure of the lower esophageal sphincter though other factors, such as the use of nasogastric tubes, treatment with adrenergic agonists, bronchodilators, or opiates and mechanical ventilation, can further increase the risk of GER. Vomiting and regurgitation are the most common manifestations in infants and are considered pathological when they have repercussions on the nutritional status. In critically ill children, damage to the esophageal mucosa predisposes to digestive tract hemorrhage and nosocomial pneumonia secondary to repeated microaspiration. GER is mainly alkaline in children, as is also the case in critically ill pediatric patients. pH-metry combined with multichannel intraluminal impedance is therefore the technique of choice for diagnosis. The proton pump inhibitors are the drugs of choice for the treatment of GER because they have a greater effect, longer duration of action, and a good safety profile.

Abstract
No test can provide a definitive diagnosis of aerodigestive disease. When interpreting tests, one should weigh the benefits and weaknesses of different technologies and methods, scientific appropriateness of the testing conditions, clinicopathologic correlation, and pharmacologic approaches. Gastroesophageal reflux disease (GERD) symptoms and airway symptoms can coexist, and they cannot be distinguished without specific testing and direct observations. Important aerodigestive disorders include dysphagia, GERD, and aggravation of airway injury due to malfunctions of swallowing or airway protection mechanisms. Objective evaluation of aerodigestive reflexes and symptom correlation may provide support for evidence-based personalized management of feeding and airway protection strategies.

Abstract
Nursing’s goal is to be the least invasive as the patient's condition allows. As a NICU nurse, each feeding for our patients is a priority for them to grow and develop with the idea to speed discharge to home. When infants develop reflux or have increased gastric aspirates, we are concerned that their weight will taper and their length of stay will increase. Positioning provides nurses with a noninvasive option to care for these patients. The that the right-side position is best for infants to enhance digestion stems from theories of anatomy and physics. Research strengthens this supposition for those infants needing help with decreased gastric motility. Other research supports the left lateral and prone positions for those patients with GER. In practice, a patient does not necessarily have one or the other and in fact may have both GER and slowed gastric motility at any given time. The literature supports the right lateral position for enhancing gastric emptying or motility and left lateral position for GER in the uncomplicated patient with one gastrointestinal concern. The knowledge the research provides is encouraging to provide a solution, but it does not clarify the true issues of a complex patient who can have decreased gastric motility needing the right lateral position and also suffer from symptoms of GER requiring the left lateral position (see Table). For those more complicated infants, the solution might best be choosing the prone position. The prone position should not be forgotten as the findings of many studies, although not often the first choice (best results) showed it to be consistently the second best for digestive problems. In any case, the dominant positions appear to be the right or left lateral side with the prone position considered a reasonable compromise. Further research is needed to provide a clear choice for correct positioning in the NICU population. The reality for nurses is that neonatal patients are often fed every 3 hours and their lives depend on each feeding to provide nutrients for growth. It is ideal for these patients to receive every prescribed feeding and be comfortably placed in a variety of positions. Nurses' assumption that the right lateral position is best is considered, in most cases, to be a true statement for those infants with increased gastric aspirates. For those patients with GER, the left lateral position is more highly preferred. It is important for nurses to be aware of the literature but also guide their practice based on the patient assessment and presentation of symptoms. Future knowledge may provide nurses with the data needed to perfect positioning methods for infants with feeding intolerances.

Abstract
Purpose Gastro-esophageal reflux (GER), particularly non-acid reflux, is common in infants and is a known cause of chronic respiratory symptoms in infancy. Recent guidelines recommended empirical acid suppression therapy and the head-up position in patients with suspected GER. However, the efficacy of the upright position in relieving GER and reflux-related respiratory symptoms in infants is unclear. We conducted this study to investigate the efficacy of the upright position on GER and reflux-related respiratory symptoms in infants with chronic respiratory symptoms. Methods Thirty-two infants (21 male; median age, 5 months; range, 0 to 19 months) with unexplained chronic respiratory symptoms underwent multi-channel intraluminal esophageal impedance and pH monitoring. We retrospectively compared the frequencies of GER and reflux-related symptoms according to body position. Results A mean of 3.30 episodes of reflux per hour was detected. Overall, refluxes were more frequent during the postprandial period than the emptying period (3.77 vs. 2.79 episodes/hour, respectively; P=0.01). Although there was no significant difference in the total refluxes per hour between the upright and recumbent positions (6.12 vs. 3.77 episodes, P=0.10), reflux-related respiratory symptoms per reflux were significantly fewer in infants kept in an upright position than in a recumbent position during the postprandial period (3.07% vs. 14.75%, P=0.016). Non-acid reflux was the predominant type of reflux in infants, regardless of body position or meal time. Conclusions The upright position may reduce reflux-related respiratory symptoms, rather than reflux frequency. Thus, it may be a useful non-pharmacological treatment for infantile GER disease resistant to acid suppressants.

Abstract
BACKGROUND Feeding difficulties and gastroesophageal reflux (GER) are common problems in neonates. The authors hypothesize that GER could be influenced by feeding mechanics by evaluating the effects of feeding volumes, feeding durations, feeding flow rates, and caloric density on the chemical composition and clearance of GER in dysphagic neonates. METHODS Symptomatic dysphagic neonates (n = 35) underwent evaluation for suspected GER using pH-impedance methods. RESULTS The proportions of acid and nonacid GER were different during the first, second, and third postprandial hours (P < .0001). Prolonged feeding duration was significantly associated with decreased total, nonacid GER and BCT (P < .03). Significant positive correlations (P < .05) were detected between feeding flow rate vs frequency of total, nonacid GER and BCT. Significant positive correlation (P = .002) was noted between feeding volume and BCT. BCT decreased with each hourly interval (analysis of variance [ANOVA] P < .05); however, ACT increased with each hourly interval (ANOVA P = .05). Comparison between BCT and ACT at each postprandial hour is remarkable for longer ACT during the second and third hours after the initiation of feed (P ≤ .001). No significant correlation was noted between the milk types (breast milk or formula) or caloric density with regard to the GER characteristics. Oral-fed infants had more GER events than gavage-fed infants. CONCLUSIONS Prolonged feeding durations and slower flow rates are associated with decreased frequency of GER. Modification of feeding duration and flow rate can be a useful adjunct to ameliorate GER in dysphagic neonates.

Abstract
Patients with gastroesophageal reflux disease show an increase in esophagogastric junction (EGJ) distensibility and in frequency of transient lower esophageal sphincter relaxations (TLESR) induced by gastric distension. The objective was to study the effect of localized EGJ distension on triggering of TLESR in healthy volunteers. An esophageal manometric catheter incorporating an 8-cm internal balloon adjacent to a sleeve sensor was developed to enable continuous recording of EGJ pressure during distension of the EGJ. Inflation of the balloon doubled the cross-section of the trans-sphincteric portion of the catheter from 5 mm OD (round) to 5 × 11 mm (oval). Ten healthy subjects were included. After catheter placement and a 30-min adaptation period, the EGJ was randomly distended or not, followed by a 45-min baseline recording. Subjects consumed a refluxogenic meal, and recordings were made for 3 h postprandially. A repeat study was performed on another day with EGJ distension status reversed. Additionally, in one subject MRI was performed to establish the exact position of the balloon in the inflated state. The number of TLESR increased during periods of EGJ distension with the effect being greater after a meal [baseline: 2.0(0.0-4.0) vs. 4.0(1.0-11.0), P=0.04; postprandial: 15.5(10.0-33.0) vs. 22.0(17.0-58.0), P=0.007 for undistended and distended, respectively]. EGJ distension augments meal-induced triggering of TLESR in healthy volunteers. Our data suggest the existence of a population of vagal afferents located at sites in/around the EGJ that may influence triggering of TLESR.

Abstract
Dual pH-multichannel intraluminal impedance (pH-MII) is a sensitive tool for evaluating overall gastroesophageal reflux disease, and particularly for permitting detection of nonacid reflux events. pH-MII technology is especially useful in the postprandial period or at other times when gastric contents are nonacidic.pH-MII was recently recognized by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition as being superior to pH monitoring alone for evaluation of the temporal relation between symptoms and gastroesophageal reflux. In children, pH-MII is useful to correlate symptoms with reflux (particularly nonacid reflux), to quantify reflux during tube feedings and the postprandial period, and to assess efficacy of antireflux therapy. This clinical review is simply an evidence-based overview addressing the indications, limitations, and recommended protocol for the clinical use of pH-MII in children.

Small volumes of feed can trigger transient lower esophageal sphincter relaxation and gastroesophageal reflux in the right lateral position in infants. J Pediatr 2010; 156:744-8, 748.e1. [PMID: 20097362 DOI: 10.1016/j.jpeds.2009.11.006] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2009] [Revised: 09/09/2009] [Accepted: 11/04/2009] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To investigate the threshold amount of constantly infused feed needed to trigger lower esophageal sphincter relaxation (TLESR) in the right lateral position (RLP) and left lateral position (LLP). STUDY DESIGN Eight healthy infants (3 male; gestational age: 32.9 +/- 2.4 weeks; corrected age: 36.1 +/- 1.3 weeks) were studied using an esophageal impedance-manometry catheter incorporating an intragastric infusion port. After tube placement, infants were randomly positioned in RLP or LLP. They were then tube-fed their normal feed (62.5 [40 to 75] mL) at an infusion rate of 160 mL/h. Recordings were made during the feed and 15 minutes thereafter. The study was repeated with the infant in the opposite position. RESULTS More TLESRs were triggered in the RLP compared with LLP (4.0 [3.0 to 6.0] vs 2.5 [1.0 to 3.0], P = .027). First TLESR occurred at a significantly lower infused volume in RLP compared with LLP (10.6 +/- 9.4 vs 21.0 +/- 4.9 mL, P = .006). The percentage of feed infused at time of first TLESR was significantly lower in RLP compared with LLP (17.6% +/- 15.5% vs 35.4% +/- 8.02%, P = .005). CONCLUSIONS In the RLP, TLESRs and gastroesophageal reflux are triggered at volumes unlikely to induce gastric distension.

Abstract
BACKGROUND AND AIM The present study aims to explore if and when acid (pH) refluxes can predict refluxes detected by multichannel intraluminal impedance (MII) studies. This correlation may indicate whether pH probe-only and MII-pH studies are interchangeable. METHODS Prospective observational cross sectional study of symptomatic children (below 18 years) who had MII-pH studies done for gastroesophageal reflux. Clinical data were extracted from patient records. Non-parametric tests, Pearson's rho and receiver operating characteristic (ROC) curves were used for data analysis. RESULTS A total of 153 children were included in the study and 62% were on acid suppression. Indices for acid and MII refluxes correlated with each other only in those without acid suppression. This correlation was lost in children on acid suppression. There was no statistically significant difference in acid or MII reflux indices in children with or without acid suppression. Like acid reflux, indices for MII refluxes had good correlation with each other irrespective of acid suppression. Liquid and mixed MII refluxes showed excellent correlation with respective types of proximally migrating refluxes. The values for MII reflux indices derived from our patient population were in broad agreement with available pediatric and adult data. CONCLUSIONS A pH probe-only study in patients without acid suppression may reflect both acid and volume (MII) reflux activities adequately and can substitute for MII-pH study. The observed excellent correlation between acid and MII refluxes with proximal migration may justify using pH probe-only studies for extra esophageal symptoms in patients without acid suppression.

Abstract
BACKGROUND & AIMS During gastroesophageal reflux, transient lower esophageal sphincter relaxation and crural diaphragm (CD) inhibition occur concomitantly. Modifying vagus nerve control of transient lower esophageal sphincter relaxation is a major focus of development of therapeutics for gastroesophageal reflux disease, but neural mechanisms that coordinate the CD are poorly understood. METHODS Nerve tracing and immunolabeling were used to assess innervation of the diaphragm and lower esophageal sphincter in ferrets. Mechanosensory responses of vagal afferents in the CD and electromyography responses of the CD were recorded in novel in vitro preparations and in vivo. RESULTS Retrograde tracing revealed a unique population of vagal CD sensory neurons in nodose ganglia and CD motor neurons in brainstem vagal nuclei. Anterograde tracing revealed specialized vagal endings in the CD and phrenoesophageal ligament-sites of vagal afferent mechanosensitivity recorded in vitro. Spontaneous electromyography activity persisted in the CD following bilateral phrenicotomy in vivo, while vagus nerve stimulation evoked electromyography responses in the CD in vitro and in vivo. CONCLUSIONS We conclude that vagal sensory and motor neurons functionally innervate the CD and phrenoesophageal ligament. CD vagal afferents show mechanosensitivity to distortion of the gastroesophageal junction, while vagal motor neurons innervate both CD and distal esophagus and may represent a common substrate for motor control of the reflux barrier.

Protein content and fortification of human milk influence gastroesophageal reflux in preterm infants. J Pediatr Gastroenterol Nutr 2009; 49:613-8.

Abstract
OBJECTIVES : Preterm human milk (HM) may provide insufficient energy and nutrients and thus may need to be fortified. Our aim was to determine whether fat content, protein content, and osmolality of HM before and after fortification may affect gastroesophageal reflux (GER) in symptomatic preterm infants. METHODS : Gastroesophageal reflux was evaluated in 17 symptomatic preterm newborns fed naïve and fortified HM by combined pH/intraluminal-impedance monitoring (pH-MII). Human milk fat and protein content was analysed by a near-infrared reflectance analysis. Human milk osmolality was tested before and after fortification. Gastroesophageal reflux indexes measured before and after fortification were compared and were also related to HM fat and protein content and osmolality before and after fortification. RESULTS : An inverse correlation was found between naïve HM protein content and acid reflux index (RIpH: P = 0.041, rho =-0.501). After fortification, osmolality often exceeded the values recommended for infant feeds; furthermore, a statistically significant (P < 0.05) increase in nonacid reflux indexes was observed. CONCLUSIONS : Protein content of naïve HM may influence acid GER in preterm infants. A standard fortification of HM may worsen nonacid GER indexes and, due to the extreme variability in HM composition, may overcome both recommended protein intake and HM osmolality. Thus, an individualised fortification, based on the analysis of the composition of naïve HM, could optimise both nutrient intake and feeding tolerance.

Abstract
OBJECTIVE To develop a North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) international consensus on the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population. METHODS An international panel of 9 pediatric gastroenterologists and 2 epidemiologists were selected by both societies, which developed these guidelines based on the Delphi principle. Statements were based on systematic literature searches using the best-available evidence from PubMed, Cumulative Index to Nursing and Allied Health Literature, and bibliographies. The committee convened in face-to-face meetings 3 times. Consensus was achieved for all recommendations through nominal group technique, a structured, quantitative method. Articles were evaluated using the Oxford Centre for Evidence-based Medicine Levels of Evidence. Using the Oxford Grades of Recommendation, the quality of evidence of each of the recommendations made by the committee was determined and is summarized in appendices. RESULTS More than 600 articles were reviewed for this work. The document provides evidence-based guidelines for the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population. CONCLUSIONS This document is intended to be used in daily practice for the development of future clinical practice guidelines and as a basis for clinical trials.
