Abstract
Low sphincter pressure and inability of the crural diaphragm to elevate it at the esophagogastric junction are important pathophysiological mechanisms of gastroesophageal reflux disease (GERD). The object of this study was to depict how Nissen fundoplication changed the resting and inspiratory pressures of the anti-reflux barrier. We selected 14 patients (eight males; mean age 42.7 years; mean body mass index 27.8) for surgery. They answered symptoms questionnaires and underwent high-resolution manometry (HRM) before and 6 months after Nissen fundoplication. We used a standard manometric protocol (resting and liquid swallows) and assessment of esophagogastric junction (EGJ) pressure metrics during standardized forced inspiratory maneuvers against increasing loads (Threshold Maneuvers). We used the Wilcoxon test for comparison of pre and postoperative data. After fundoplication, heartburn and regurgitation scores diminished remarkably (from 4.5 and 2, respectively, to zero; P = 0.002 and P = 0.0005, respective medians). Also, the median expiratory EGJ pressure had a significant increase from 8.1 to 18.1 mmHg (P = 0.002), while mean respiratory pressure and EGJ contractility integral (EGJ-CI) increased without statistical significance (P = 0.064 and P = 0.06, respectively). Axial EGJ displacement was lower after fundoplication. The EGJ relaxation pressure (P = 0.001), the mean distal esophageal intrabolus pressure (P = 0.01) and the distal latency (P = 0.017) increased after fundoplication. There was a reduction in the contraction front velocity (P = 0.043). During evaluation with standardized inspiratory maneuvers, the inspiratory EGJ pressures (under loads of 12, 24, 36 and 48 cmH2O) were lower after surgery for all loads (median for load 12 cmH2O: 145.6 vs. 102.7 mmHg; P = 0.004). Fundoplication and hiatal closure increased the expiratory EGJ pressure and promoted a great GERD symptom relief. The surgery seemed to overcompensate a reduced EGJ mobility and inspiratory pressure.

Abstract
The pathogenesis of gastroesophageal reflux disease (GERD) is multifactorial. The severity of abnormal reflux burden corresponds to the dysfunction of the antireflux barrier and inability to clear refluxate. The crural diaphragm is one of the main components of the esophagogastric junction and plays an important role in preventing gastroesophageal reflux. The diaphragm, as a skeletal muscle, is partially under voluntary control and its dysfunction can be improved via breathing exercises. Thus, diaphragmatic breathing training (DBT) has the potential to alleviate symptoms in selected patients with GERD. High-resolution esophageal manometry (HRM) is a useful method for the assessment of antireflux barrier function and can therefore elucidate the mechanisms responsible for gastroesophageal reflux. We hypothesize that HRM can help define patient phenotypes that may benefit most from DBT, and that HRM can even help in the management of respiratory physiotherapy in patients with GERD. This systematic review aimed to evaluate the current data supporting physiotherapeutic practices in the treatment of GERD and to illustrate how HRM may guide treatment strategies focused on respiratory physiotherapy.

Abstract
Gastroesophageal reflux disease (GERD) is a common disease affecting a significant number of adults both globally and in the USA. GERD is clinically diagnosed based on patient-reported symptoms, and the gold standard for diagnosis is ambulatory reflux monitoring, a tool particularly utilized in the common scenario of non-response to therapy or atypical features. Over the past 20 years, there has been a shift toward extending the duration of reflux monitoring, initially from 24 to 48 h and more recently to 96 h, primarily based on a demonstrated increase in diagnostic yield. Further, multiple studies demonstrate clinically relevant variability in day-to-day acid exposure levels in nearly 30% of ambulatory reflux monitoring studies. For these reasons, an ongoing clinical dilemma relates to the optimal activities patients should engage in during prolonged reflux monitoring. Thus, the aims of this review are to detail what is known about variability in daily acid exposure, discuss factors that are known to influence this day-to-day variability (i.e., sleep patterns, dietary/eating habits, stress, exercise, and medications), and finally provide suggestions for patient education and general GERD management to reduce variation in esophageal acid exposure levels.

Abstract
Gastroesophageal reflux (GOR) is defined as "the passage of gastric contents into the esophagus with or without regurgitation and vomiting" and gastroesophageal reflux disease (GORD) is defined "when GOR leads to troublesome symptoms affecting the daily functioning and/or complications." This definition was first developed in 2006 by the Montreal consensus group (1) and later on adopted by pediatric gastroenterology societies such as ESPGHAN and NASPGHAN in 2009 (2). The definition of gastroesophageal reflux reveals little about its pathophysiology and is focused on symptomatology. In this way, it acts as an umbrella term for the multifactorial causes of the disease and the various phenotypes encountered; from functional heartburn to hypersensitive esophagus and nonerosive reflux disease, to erosive esophagitis and Barrett's esophagus. This article is devoted to the pathophysiology of pediatric GORD in comparison to adult GORD and is divided in 2 parts. In the first part, we will systematically describe the different mechanisms for the generation and clearance of reflux events, while on the second part we will discuss the mechanisms involved in symptoms generation. Finally, we will discuss the similarities and differences between pediatric and adult GORD.

Abstract
OBJECTIVES Dysfunctions in the lower esophageal sphincter (LES) and the upper esophageal sphincter (UES) levels can occur owing to poor muscle coordination, contraction, or relaxation. Such condition can possibly be addressed by functional rehabilitation. The aim of this study was to measure pressure changes in the UES and LES at rest and during routine rehabilitation techniques, that is, cervical manual traction and trunk stabilization maneuver. METHODS This study was conducted in a University Hospital Gastrointestinal Endoscopy Center. Cervical manual traction and a trunk stabilization maneuver were performed in a convenient group of 54 adult patients with gastroesophageal reflux disease. High-resolution manometry was used to measure pressure changes in the LES and UES at rest and during manual cervical traction and trunk stabilization maneuver. RESULTS Average initial resting UES pressure was 90.91 mmHg. A significant decrease was identified during both cervical traction (average UES pressure = 42.13 mmHg, P < .001) and trunk stabilization maneuver (average UES pressure = 62.74 mmHg, P = .002). The average initial resting LES pressure was 14.31 mmHg. A significant increase in LES pressure was identified both during cervical traction (average LES pressure = 21.39 mmHg, P < .001) and during the trunk stabilization maneuver, (average pressure = 24.09 mmHg, P < .001). CONCLUSION Cervical traction and trunk stabilization maneuvers can be used to decrease pressure in the UES and increase LES pressure in patients with gastroesophageal reflux disease.

Effects of upper airway obstruction or hypoxia on gastroesophageal reflux in newborn lambs. Pediatr Res 2021; 89:496-501. [PMID: 32357360 DOI: 10.1038/s41390-020-0920-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 03/13/2020] [Accepted: 04/13/2020] [Indexed: 11/09/2022]
Abstract
BACKGROUND Although it is commonly accepted that upper airway obstruction (UAO) increases gastroesophageal reflux (GER), the link is poorly understood and insufficiently documented. In addition, while hypoxia is often encountered in infants with UAO, its consequences on GER are virtually unknown. The two aims of the present study were to characterize the effects of (1) UAO and (2) hypoxia on GER. METHODS Seventeen lambs underwent polysomnographic and esophageal impedance/pH-metry monitoring during UAO vs. a control condition (6 h, ten lambs) or 10% hypoxia vs. normoxic condition (3 h, seven other lambs). RESULTS Moderate-to-severe UAO was maintained throughout monitoring (inspiratory tracheal pressure of -13 (-15, -12) cm H2O vs. -1 (-1, -1) cm H2O in control condition, p = 0.005). While the number of GERs increased with UAO (2 (1, 4) vs. 0 (0, 3) in the control condition, p = 0.03), the increase was less than anticipated and inconsistent among the lambs. Also, sustained 10% hypoxia did not alter the number of GERs (2 (1, 3) vs. 0 (0, 5) in the control condition, p = 0.9). CONCLUSIONS The presence of an UAO for 6 h mildly increased the number of GERs, whereas hypoxia for 3 h had no significant effect. IMPACT The effect of upper airway obstruction and hypoxia on gastroesophageal reflux is poorly documented in the neonatal period. A moderate-to-severe upper airway obstruction for 6 h results in a mild, inconsistent increase in the number of gastroesophageal refluxes. Overall, a hypoxia of 10% for 3 h had no significant impact on gastroesophageal reflux. The prescription of an antireflux medication in infants with upper airway obstruction must not be systematic but rely on objective signs of a pathologic gastroesophageal reflux.

Abstract
AIMS To investigate the effects and possible mechanisms of transcutaneous electrical acustimulation (TEA) combined with deep breathing training (DBT) on refractory gastroesophageal reflux disease (rGERD). METHODS Twenty-one patients with rGERD were recruited and randomly assigned to receive either only esomeprazole (ESO, 20 mg bid) (group A, n = 7), TEA + DBT + ESO (group B, n = 7), or sham-TEA + DBT + ESO (group C, n = 7) in a four-week study. The reflux diagnostic questionnaire (RDQ) score and heart rate variability (HRV) were recorded and evaluated at baseline and at the end of each treatment. Blood samples were collected for the measurement of serum acetylcholine (Ach) and nitric oxide (NO). Esophageal manometry and 24-hour pH monitoring were performed before and after the treatment. RESULTS After treatment, 1) the participants in group B had significantly lower scores of RDQ and DeMeester and increased lower esophageal sphincter pressure (LESP) than those in group C (all p < 0.05), suggesting the role of TEA; 2) low frequency band (LF)/(LF + HF) ratio in groups B and C was decreased, compared with group A (p = 0.010, p = 0.042, respectively); high frequency band (HF)/(LF + HF) ratio in B and C groups was significantly increased, compared with group A (p = 0.010, p = 0.042, respectively); 3) The serum Ach in groups B and C was significantly higher than group A (p = 0.022, p = 0.046, respectively); the serum NO in groups B and C was significantly lower than group A (p = 0.010, p = 0.027, respectively). CONCLUSIONS TEA combined with the DBT can effectively improve the reflux symptoms in rGERD patients by increasing LESP and reducing gastroesophageal reflux, which may be mediated via the autonomic and enteric mechanisms.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GERD) is one of the most common diseases, but is still a challenge to cure. Different medical treatments are used, first of all Proton pump inhibitors (PPIs), however these are sometimes ineffective and long-term intake can lead to underestimated complications. Recently, some studies investigated the role of inspiratory muscle training (IMT) in the medical treatment of GERD. It seems that IMT is able to increase the pressure generated by the lower oesophageal sphincter (LES), reduce spontaneous releases of LES, acid exposure, use of PPIs, and improve symptoms and quality of life for GERD patients. OBJECTIVE The aim of this study was to evaluate the effectiveness of IMT in association with myofunctional therapy exercises of swallowing set by Daniel Garliner (m-IMT) on the symptoms of patients with non-erosive gastro-oesophageal reflux disease (NERD). METHODS Twenty-one adult patients with NERD were enrolled from May to December 2017 and performed m-IMT over a period of 4 weeks. Before and after treatment, all the patients completed the following questionnaires: GERD oesophageal symptomatology (GERDQ), extra-oesophageal GERD symptomatology (RSI), quality of life (GERD-Health Related Quality of Life Questionnaire (GERD-HRQL), and underwent laryngeal endoscopy. RESULTS Nineteen patients completed m-IMT. GERDQ (from 8.36±3.94 to 1.7±3.41; p<.05), RSI (from to 21.68±10.26 to 6.93±8.37; p<.05) and GERDHRQL (from 25.68±16.03 to 8.4±11.06; p<.05) the questionnaire scores significantly reduced after treatment. In addition, the laryngeal endoscopy score greatly improved (from 14.24±4.15 to 7.4±1.77; p<.05). CONCLUSIONS m-IMT is a low cost therapy without side effects. It could be useful in association with PPI or alone for selected GERD cases and for mild NERD forms, in association with diet. Further studies are required to prove the effects of m-IMT on GERD symptoms and decide the best treatment schedule.

Abstract
Background: Cardiorespiratory limitation is a common hallmark of cardiovascular disease which is a key component of pharmacological and exercise treatments. More recently, inspiratory muscle training (IMT) is becoming an effective complementary treatment with positive effects on muscle strength and exercise capacity. We assessed the effectiveness of IMT on the cardiovascular system through autonomic function modulation via heart rate variability and arterial blood pressure. Methods: Randomized controlled trials (RCTs) were identified from searches of The Cochrane Library, MEDLINE and EMBASE to November 2018. Citations, conference proceedings and previous reviews were included without population restriction, comparing IMT intervention to no treatment, placebo or active control. Results: We identified 10 RCTs involving 267 subjects (mean age range 51–71 years). IMT programs targeted maximum inspiratory pressure (MIP) and cardiovascular outcomes, using low (n=6) and moderate to high intensity (n=4) protocols, but the protocols varied considerably (duration: 1–12 weeks, frequency: 3–14 times/week, time: 10–30 mins). An overall increase of the MIP (cmH2O) was observed (−27.57 95% CI −18.48, −37.45, I2=64%), according to weighted mean difference (95%CI), and was accompanied by a reduction of the low to high frequency ratio (−0.72 95% CI−1.40, −0.05, I2=50%). In a subgroup analysis, low- and moderate-intensity IMT treatment was associated with a reduction of the heart rate (HR) (−7.59 95% CI −13.96, −1.22 bpm, I2=0%) and diastolic blood pressure (DBP) (−8.29 [−11.64, −4.94 mmHg], I2=0%), respectively. Conclusion: IMT is an effective treatment for inspiratory muscle weakness in several populations and could be considered as a complementary treatment to improve the cardiovascular system, mainly HR and DBP. Further research is required to better understand the above findings.

Abstract
The purpose of this study is to investigate whether implementing a myofascial release (MFR) protocol designed to restore the myofascial properties of the diaphragm has any effect on the symptoms, quality of life, and consumption of proton pump inhibitors (PPI) drugs by patients with non-erosive gastroesophageal reflux disease (GERD). We randomized 30 patients with GERD into a MFR group or a sham group. Changes in symptomatology and quality of life were measured with the Reflux Disease Questionnaire and the Gastrointestinal Quality of Life Index. Need of PPIs was measured as the milligrams of drug intake over the 7 days prior to each assessment. All variables were assessed at baseline, one week and 4 weeks after the end of the treatment. At week 4, patients receiving MFR showed significant improvements in symptomatology (mean difference-1.1; 95% CI: -1.7 to -0.5), gastrointestinal quality of life (mean difference 18.1; 95% CI: 4.8 to 31.5), and PPIs use (mean difference-97 mg; 95% CI: -162 to -32), compared to the sham group. These preliminary findings indicate that the application of the MFR protocol we used in this study decreased the symptoms and PPIs usage and increased the quality of life of patients with non-erosive GERD up to four weeks after the end of the treatment.

Abstract
Aspiration is a syndrome with variable respiratory manifestations that span acute, life-threatening illnesses, such as acute respiratory distress syndrome, to chronic, sometimes insidious, respiratory disorders such as aspiration bronchiolitis. Diagnostic testing is limited by the insensitivity of histologic testing, and although gastric biomarkers for aspiration are increasingly available, none have been clinically validated. The leading mechanism for microaspiration is thought to be gastroesophageal reflux disease, largely driven by the increased prevalence of gastroesophageal reflux across a variety of respiratory disorders, including chronic obstructive pulmonary disease, asthma, idiopathic pulmonary fibrosis, and chronic cough. Failure of therapies targeting gastric acidity in clinical trials, in addition to increasing concerns about both the overuse of and adverse events associated with proton pump inhibitors, raise questions about the precise mechanism and causal link between gastroesophageal reflux and respiratory disease. Our review summarizes key aspiration syndromes with a focus on reflux-mediated aspiration and highlights the need for additional mechanistic studies to find more effective therapies for aspiration syndromes.

de Abreu RM, Rehder-Santos P, Minatel V, Dos Santos GL, Catai AM. Effects of inspiratory muscle training on cardiovascular autonomic control: A systematic review. Auton Neurosci 2017; 208:29-35. [PMID: 28916152 DOI: 10.1016/j.autneu.2017.09.002] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Revised: 08/24/2017] [Accepted: 09/05/2017] [Indexed: 11/26/2022]
Abstract
PURPOSE To carry out a systematic review to determine if inspiratory muscle training (IMT) promotes changes in cardiovascular autonomic responses in humans. METHODS The methodology followed the PRISMA statement for reporting systematic review analysis. MEDLINE, PEDro, SCOPUS and PubMed electronic databases were searched from the inception to March 2017. The quality assessment was performed using a PEDro scale. The articles were included if: (1) primary objective was related to the effects of IMT on the cardiovascular autonomic nervous system, and (2) randomized clinical trials and quasi-experimental studies. Exclusion criteria were reviews, short communications, letters, case studies, guidelines, theses, dissertations, qualitative studies, scientific conference abstracts, studies on animals, non-English language articles and articles addressing other breathing techniques. Outcomes evaluated were measures of cardiovascular autonomic control, represented by heart rate variability (HRV) and blood pressure variability (BPV) indexes. RESULTS The search identified 729 citations and a total of 6 studies were included. The results demonstrated that IMT performed at low intensities can chronically promote an increase in the parasympathetic modulation and/or reduction of sympathetic cardiac modulation in patients with diabetes, hypertension, chronic heart failure and gastroesophageal reflux, when assessed by HRV spectral analysis. However, there was no study which evaluated the effects of IMT on cardiovascular autonomic control assessed by BPV. CONCLUSIONS IMT can promote benefits for cardiac autonomic control, however the heterogeneity of populations associated with different protocols, few studies reported in the literature and the lack of randomized controlled trials make the effects of IMT on cardiovascular autonomic control inconclusive.

Abstract
BACKGROUND Erosive reflux disease (ERD) is prevalent in the West, and its incidence is increasing in the East. The differences between the West and East, especially in body composition, have not been investigated thoroughly. METHODS Subjects who underwent esophagogastroduodenoscopy and body composition analysis during health screening were analyzed retrospectively. Russian Caucasians who visited Korea were propensity matched with native Koreans. Endoscopy results were analyzed to identify ERD and gastroesophageal flap valve (GEFV) status. Body composition and laboratory results were compared to identify risk factors for ERD. KEY RESULTS 32 279 subjects underwent health screening with 1496 Russian Caucasians propensity matched with 1496 Koreans. ERD prevalence was 20.2% for Caucasians and 9.8% for Koreans (P<.001). Caucasians had significantly greater body mass index (BMI) and were more sarcopenic. Significant risk factors for ERD were Caucasian ethnicity (OR 1.629, 95% CI 1.265-2.099, P<.001), male gender (OR 2.374, 95% CI 1.883-2.993, P<.001), greater BMI (OR 1.067, 95% CI 1.041-1.093, P<.001), and abnormal GEFV (OR 2.730, 95% CI 2.194-3.397, P<.001). H. pylori seropositivity (OR 0.614, 95% CI 0.488-0.774, P<.001) and atrophic gastritis (OR 0.547, 95% CI 0.411-0.728, P<.001) were significantly preventive. CONCLUSIONS & INFERENCES Caucasian ethnicity is a significant risk factor for ERD. Greater BMI, male gender and abnormal GEFV are associated with ERD, and H. pylori seropositivity and atrophic gastritis are preventive. Further studies are needed to assess the differences in ERD between Caucasians and East Asians.

Abstract
BACKGROUND Inspiratory esophagogastric junction (EGJ) pressure is lower in gastroesophageal reflux disease (GERD) and patients fail to increase EGJ pressure during the inspiratory effort. The aim of this study was to assess the EGJ activity during inspiratory maneuvers (high-resolution manometry, HRM) and the crural diaphragm (CD) thickness (endoscopic ultrasound, EUS) in GERD. METHODS Twenty esophagitis patients (average age 45 years, 7 grade A, 13 grade B) had HRM and EUS. Forty-three controls were recruited; 30 had HRM (average age 33 years), and 13 had EUS (average age 40 years). The EGJ contractility index (EGJ-CI) (mm Hg×cm) was measured during normal respiration and two inspiratory maneuvers: without and with inspiratory loads of 12, 24, and 48 cmH2 O (TH-maneuvers). A composite metric for TH-maneuvers ("EGJ total activity") was defined as the product of the maximal EGJ pressure and the length of its aboral excursion during the maneuver (mm Hg×cm). The CD thickness (cm) was measured during expiration (12 MHz). KEY RESULTS Expiratory lower esophageal sphincter pressure and integrated relaxation pressure were lower in GERD. The EGJ-CI and the "EGJ total activity" were lower in GERD during TH-maneuvers (48-cmH2 O load: 168.4 ± 13.8 vs 114.8 ± 9.6, P=.006). Patients failed to sustain the inspiratory CD activity across the 12 and 48-cmH2 O efforts. The CD was thinner in GERD patients (0.37 ± 0.03 vs 0.49 ± 0.04, P=.02). The CD thickness correlated with the increment in the "EGJ total activity" in GERD without a hiatal hernia (r=.702, P=.016, n=11). CONCLUSIONS & INFERENCES There are anatomical changes and functional failure of the CD in esophagitis patients supporting the possibility of a skeletal muscle deficiency in GERD.

Abstract
This study investigated the effectiveness of diaphragm biofeedback training (DBT) for patients with gastroesophageal reflux disease (GERD). A total of 40 patients with GERD treated at the Peking Union Medical College Hospital between September 2004 and July 2006 were randomized to receive DBT and rabeprazole proton pump inhibitor (PPI) or rabeprazole alone. The DBT + rabeprazole group received DBT during the 8-week initial treatment; the rabeprazole group did not. During the 6-month follow up, all patients took acid suppression according to their reflux symptoms, and the patients in the DBT + rabeprazole group were required to continue DBT. The primary outcome (used for power analysis) was the amount of acid suppression used at 6 months. Secondary outcomes were reflux symptoms, health-related quality of life (HRQL), and esophageal motility differences after the 8-week treatment compared with baseline. Acid suppression usage significantly decreased in the DBT + rabeprazole group compared with the rabeprazole group at 6 months (P < 0.05). At 8 weeks, reflux symptoms and GERD-HRQL were significantly improved in both groups (P < 0.05), without difference between them. Crural diaphragm tension (CDT) and gastroesophageal junction pressure (GEJP) significantly increased in the DBT + rabeprazole group (P < 0.05), but without change in lower esophageal sphincter (LES) pressure. There was no significant change in CDT, GEJP, and LES pressure compared with baseline in the rabeprazole group. In conclusion, long-term DBT could reduce acid suppression usage by enhancing the anti-reflux barrier, providing a non-pharmacological maintenance therapy and reducing medical costs for patients with GERD.

Abstract
BACKGROUND Through rhythmic variations, the diaphragm influence lower esophageal sphincter (LES) pressure acting as an external sphincter. LES pressure recording is characterized by increased pressure in inspiration due to contraction of the diaphragmatic crura that involves the sphincter. AIM To describe a method of measuring LES pressure during standardized inspiratory maneuvers with increasing loads. METHODS The study population comprised of eight healthy female volunteers (average age of 31.5 years). An esophageal high-resolution manometry and impedance system was used for measuring the LES pressure during 3-second inspiratory efforts under 12, 24 and 48 cm H2O loads (Threshold maneuvers). RESULTS There was a significant difference between the average maximum LES pressure and the average maximum basal LES pressure during the first (76.19±17.92 difference, p=0.0008), second (86.92±19.01 difference, p=0.0004), and third seconds of the maneuver (90.86±17.93 difference, p=0.0002), with 12, 24 and 48 cmH2O loads. CONCLUSION This maneuver is a standardization of the inspiratory LES pressure and may better differentiate patients with reflux disease from healthy individuals, and may also be useful for monitoring the treatment of these patients through inspiratory muscle training.

Abstract
The respiratory diaphragm is the most important muscle for breathing. It contributes to various processes such as expectoration, vomiting, swallowing, urination, and defecation. It facilitates the venous and lymphatic return and helps viscera located above and below the diaphragm to work properly. Its activity is fundamental in the maintenance of posture and body position changes. It can affect the pain perception and emotional state. Many authors reported on diaphragmatic training by using special instruments, whereas only a few studies focused on manual therapy approaches. To the knowledge of the authors, the existing scientific literature does not exhaustively examines the manual evaluation of the diaphragm in its different portions. A complete evaluation of the diaphragm is mandatory for several professional subjects, such as physiotherapists, osteopaths, and chiropractors not only to elaborate a treatment strategy but also to obtain information on the validity of the training performed on the patient. This article aims to describe a strategy of manual evaluation of the diaphragm, with particular attention to anatomical fundamentals, in order to stimulate further research on this less explored field.

Abstract
Gastro-oesophageal reflux is associated with a wide range of respiratory disorders, including asthma, isolated chronic cough, idiopathic pulmonary fibrosis, chronic obstructive pulmonary disease and cystic fibrosis. Reflux can be substantial and reach the proximal margins of the oesophagus in some individuals with specific pulmonary diseases, suggesting that this association is more than a coincidence. Proximal oesophageal reflux in particular has led to concern that microaspiration might have an important, possibly even causal, role in respiratory disease. Interestingly, reflux is not always accompanied by typical reflux symptoms, such as heartburn and/or regurgitation, leading many clinicians to empirically treat for possible gastro-oesophageal reflux. Indeed, costs associated with use of acid suppressants in pulmonary disease far outweigh those in typical GERD, despite little evidence of therapeutic benefit in clinical trials. This Review comprehensively examines the possible mechanisms that might link pulmonary disease and oesophageal reflux, highlighting the gaps in current knowledge and limitations of previous research, and helping to shed light on the frequent failure of antireflux treatments in pulmonary disease.

Abstract
BACKGROUND While high resolution esophageal manometry combined with impedancometry has demonstrated that gastric pressurizations lead to rumination, the contribution of upper esophageal sphincter (UES) and esophagogastric junction (EGJ) function to rumination is unclear. Behavioral therapy with diaphragmatic breathing (DB) can reduce rumination. We aimed to evaluate the pressures in the stomach, EGJ and UES during rumination and the effects of DB augmented with biofeedback therapy. METHODS Sixteen patients with rumination were studied with manometry and impedancometry before and after a meal. The postprandial assessment comprised three periods: before, during, and after DB augmented with biofeedback therapy. KEY RESULTS All patients had postprandial rumination, which was associated (p < 0.001) with increased gastric pressure and reversal of the postprandial gastroesophageal pressure gradient from -4 (-43 to 18) before to 20 (7-79) mmHg during rumination. The EGJ pressure was lower (p < 0.001) during gastric pressurizations that were associated with rumination vs those that were not. The UES also relaxed, almost completely, during rumination. Patients had a median (range) of 5 (2-10) rumination episodes before, 1 (0-2) (p < 0.001) during, and 3 (1-5) after (p < 0.001 vs during) diaphragmatic breathing. During manometry and impedancometry, DB was well-tolerated and learned within 5 min. Diaphragmatic breathing increased EGJ pressure (p < 0.001) and restored a negative gastroesophageal pressure gradient (-20 mmHg [-80 to 7]). CONCLUSIONS & INFERENCES Diaphragmatic breathing aided with high resolution esophageal manometry is well-tolerated, effective and averts the gastroesophageal pressure disturbance that leads to rumination.

Abstract
Gastroesophageal reflux disease (GERD) is a frequent disorder which is expensive to diagnose and treat. Initiating therapy with empiric trial of proton-pump inhibitor is a well established strategy; however, symptoms of GERD do often persist regardless of effective medication. Nowadays, increasing interest concerning the efficacy and safety of chronic acid suppression with proton-pump inhibitors (PPIs), prompts a consideration for GERD treatment strategies related to the basic physiology of the lower esophageal sphincter, including modulation of its tone and ending of spontaneous transient lower esophageal sphincter relaxation, which contributes to reflux. Together, the lower esophageal sphincter and the crural diaphragm represent the major antireflux barrier, protecting the esophagus from reflux of gastric content. In order to prevent the need for enduring PPIs therapy or surgical procedures, substitute therapeutics approaches are being researched. Recently, studies have focused on the response of the respiratory muscles to inspiratory muscle training. As a result, inspiratory muscle training has emerged as a potential alternative for treatment of gastroesophageal reflux. The present report reviews the physiologic factors contributing to GERD, and presents the newly developed therapies that can be applied either alone or in association with available efficient GERD therapy.

Abstract
AIM: To investigate crural diaphragm (CD) function in systemic sclerosis (SSc) using high-resolution manometry and standardized inspiratory maneuvers.
METHODS: Eight SSc volunteers (average age, 40.1 years; one male) and 13 controls (average age, 32.2 years; six males) participated in the study. A high-resolution manometry/impedance system measured the esophagus and esophagogastric junction (EGJ) pressure profile during swallows and two respiratory maneuvers: sinus arrhythmia maneuver (SAM; the average of six EGJ peak pressures during 5-s deep inhalations) and threshold maneuver (TM; the EGJ peak pressures during forced inhalation under 12 and 24 cmH2O loads). Inspiratory diaphragm lowering (IDL) was taken as the displacement of the EGJ high-pressure zone during the SAM.
RESULTS: SSc patients had lower mean lower esophageal sphincter pressure than controls during normal breathing (19.7 ± 2.8 mmHg vs 32.2 ± 2.7 mmHg, P = 0.007). Sinus arrhythmia maneuver pressure was higher in SSc patients than in controls (142.6 ± 9.4 mmHg vs 104.6 ± 13.8 mmHg, P = 0.019). Sinus arrhythmia maneuver pressure normalized to IDL was also higher in SSc patients than in controls (83.8 ± 13.4 mmHg vs 37.5 ± 6.9 mmHg, P = 0.005). Threshold maneuver pressures normalized to IDL were also greater in SSc patients than in controls (TM 12 cmH2O: 85.1 ± 16.4 mmHg vs 43.9 ± 6.3 mmHg, P = 0.039; TM 24 cmH2O: 85.2 ± 16.4 mmHg vs 46.2 ± 6.6 mmHg, P = 0.065). Inspiratory diaphragm lowering in SSc patients was less than in controls (2.1 ± 0.3 cm vs 3 ± 0.2 cm, P = 0.011).
CONCLUSION: SSc patients had increased inspiratory EGJ pressure. This is an add-on to EGJ pressure and indicates that the antireflux barrier can be trained.
