Abstract
High-resolution esophageal manometry [HRM] has become the gold standard for the evaluation of esophageal motility disorders. It is unclear whether there are HRM differences in diagnostic outcome based on regional or geographic distribution. The diagnostic outcome of HRM in a diverse geographical population of Mexico was compared and determined if there is variability in diagnostic results among referral centers. Consecutive patients referred for HRM during 2016-2020 were included. Four major referral centers in Mexico participated in the study: northeastern, southeastern, and central (Mexico City, two centers). All studies were interpreted by experienced investigators using Chicago Classification 3 and the same technology. A total of 2293 consecutive patients were included. More abnormal studies were found in the center (61.3%) versus south (45.8%) or north (45.2%) P < 0.001. Higher prevalence of achalasia was noted in the south (21.5%) versus center (12.4%) versus north (9.5%) P < 0.001. Hypercontractile disorders were more common in the north (11.0%) versus the south (5.2%) or the center (3.6%) P.001. A higher frequency of weak peristalsis occurred in the center (76.8%) versus the north (74.2%) or the south (69.2%) P < 0.033. Gastroesophageal junction obstruction was diagnosed in (7.2%) in the center versus the (5.3%) in the north and (4.2%) in the south p.141 (ns). This is the first study to address the diagnostic outcome of HRM in diverse geographical regions of Mexico. We identified several significant diagnostic differences across geographical centers. Our study provides the basis for further analysis of the causes contributing to these differences.

Abstract
Background/Aims There is an increased incidence of gastroesophageal reflux disease (GERD) after lung transplantation (LT) that can be associated with graft dysfunction. It is unclear if the underlying esophageal motility changes in GERD are different following LT. This study aimed to use esophageal high-resolution manometry (HRM) to explore GERD mechanisms in LT recipients compared to matched controls. Methods This was a retrospective study including patients with pathologic acid reflux who underwent HRM and pH testing at our healthcare facility July 2012 to October 2019. The study included 12 LT recipients and 36 controls. Controls were matched in a 1:3 ratio for age, gender, and acid exposure time (AET). Results LT recipients had less hypotensive esophagogastric junction (EGJ) (mean EGJ-contractile integral 89.2 mmHg/cm in LT vs 33.9 mmHg/cm in controls, P < 0.001). AET correlated with distal contractile integral and total EGJ-contractile integral only in LT group (r = -0.79, P = 0.002 and r = -0.57, P = 0.051, respectively). Conclusions Following LT, acid reflux is characterized by a less hypotensive EGJ compared to controls with similar AET. The strongest correlation with AET after LT was found to be esophageal peristaltic vigor. These results add to the understanding of reflux after LT and may help tailor an individualized treatment plan.

Abstract
OBJECTIVE To identify the characteristics of the time-point distribution of the occurrence of hypopharyngeal-proximal reflux episodes (HREs) in elderly and younger patients with laryngopharyngeal reflux (LPR). STUDY DESIGN Retrospective cohort study. SETTING Analysis of data from patients with LPR-related symptoms and 24-hour hypopharyngeal-esophageal multichannel intraluminal impedance-pH (24-hour HEMII-pH) monitoring from February 2017 to September 2022 at Sixth Medical Center of PLA General Hospital. METHODS Patients were divided into 2 age groups: the elderly group (>60 years) and the younger group (≤60 years). The time series of HREs and meals within 24 hours were analyzed based on HEMII-pH. RESULTS A total of 305 patients were included (126 elderly patients). In younger patients, except for nonacid-gas HREs, the incidence of the remaining types of HREs tended to increase within 2 hours after meals, especially after dinner. The incidence of all types of HREs pre- and postmeal was not significantly different in the elderly group (χ2 = 0.080, P = .777). The incidence of nighttime HREs in elderly patients was statistically higher than in younger patients (6.23% vs 3.96%, P = .030), particularly acid-/nonacid-liquid HREs. CONCLUSION HREs tend to increase within 2 hours after meals in younger LPR patients, except for nonacid-gas HREs. In elderly LPR patients, the incidence of all types of HREs pre- and postmeal were not significantly different, and nighttime fluid HREs was more prone to occur than in younger patients.

Abstract
The older population consisting of persons aged 65 years or older is the fastest-growing population group and also the major consumer of pharmaceutical products. Due to the heterogenous ageing process, this age group shows high interindividual variability in the dose-exposure-response relationship and, thus, a prediction of drug safety and efficacy is challenging. Although physiologically based pharmacokinetic (PBPK) modelling is a well-established tool to inform and confirm drug dosing strategies during drug development for special population groups, age-related changes in absorption are poorly accounted for in current PBPK models. The purpose of this review is to summarise the current state-of-knowledge in terms of physiological changes with increasing age that can influence the oral absorption of dosage forms. The capacity of common PBPK platforms to incorporate these changes and describe the older population is also discussed, as well as the implications of extrinsic factors such as drug-drug interactions associated with polypharmacy on the model development process. The future potential of this field will rely on addressing the gaps identified in this article, which can subsequently supplement in-vitro and in-vivo data for more robust decision-making on the adequacy of the formulation for use in older adults and inform pharmacotherapy.

Abstract
Background Morbidity and mortality in lung transplant recipients are often triggered by recurrent aspiration events, potentiated by oesophageal and gastric disorders. Previous small studies have shown conflicting associations between oesophageal function and the development of chronic lung allograft dysfunction (CLAD). Herein, we sought to investigate the relationship between oesophageal motility disorders and long-term outcomes in a large retrospective cohort of lung transplant recipients. Methods All lung transplant recipients at the Toronto Lung Transplant Program from 2012 to 2018 with available oesophageal manometry testing within the first 7 months post-transplant were included in this study. Patients were categorised according to the Chicago Classification of oesophageal disorders (v3.0). Associations between oesophageal motility disorders with the development of CLAD and allograft failure (defined as death or re-transplantation) were assessed. Results Of 487 patients, 57 (12%) had oesophagogastric junction outflow obstruction (OGJOO) and 47 (10%) had a disorder of peristalsis (eight major, 39 minor). In a multivariable analysis, OGJOO was associated with an increased risk of CLAD (HR 1.71, 95% CI 1.15-2.55, p=0.008) and allograft failure (HR 1.69, 95% CI 1.13-2.53, p=0.01). Major disorders of peristalsis were associated with an increased risk of CLAD (HR 1.55, 95% CI 1.01-2.37, p=0.04) and allograft failure (HR 3.33, 95% CI 1.53-7.25, p=0.002). Minor disorders of peristalsis were not significantly associated with CLAD or allograft failure. Conclusion Lung transplant recipients with oesophageal stasis characterised by OGJOO or major disorders of peristalsis were at an increased risk of adverse long-term outcomes. These findings will help with risk stratification of lung transplant recipients and personalisation of treatment for aspiration prevention.

High-resolution impedance manometry for comparing bolus transit between patients with non-obstructive dysphagia and asymptomatic controls. Neurogastroenterol Motil 2023; 35:e14452. [PMID: 35998271 DOI: 10.1111/nmo.14452] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 07/07/2022] [Accepted: 08/04/2022] [Indexed: 12/25/2022]
Abstract
BACKGROUND Currently, there are no high-resolution impedance manometry (HRIM)-based diagnostic criteria for non-obstructive dysphagia (NOD). New impedance parameters, such as the esophageal impedance integral (EII) and volume of inverted impedance (VII) ratios, have shown strong correlations with bolus transit. This study compared the EII and VII ratios as diagnostic tools for NOD. METHODS We analyzed 36 participants (12 patients with achalasia, 12 patients with NOD [7 with normal motility and 5 with ineffective esophageal motility], and 12 asymptomatic controls) who underwent HRIM with a maximum of 5 swallows per participant. The EII and VII ratios were calculated as Z2 (post-swallow)/Z1 (pre-swallow). Bolus transit was retrospectively evaluated using transluminal impedance analysis. KEY RESULTS Both EII and VII ratios could effectively distinguish the achalasia group from the non-achalasia groups (area under the receiver operating characteristic curve [AUROC]: 0.83 for VII vs. 0.80 for EII; p = 0.73). However, the VII ratio was significantly better in discriminating asymptomatic controls from patients with dysphagia (NOD + achalasia) (AUROC: 0.81 vs. 0.68; p = 0.01). Moreover, the VII ratio was better in discriminating asymptomatic controls from patients with NOD (AUROC: 0.68 vs. 0.51; p = 0.06). In repeated swallows, the VII ratio was consistently the lowest in controls and the highest in patients with achalasia, whereas the EII ratio did not show a consistent pattern. CONCLUSIONS & INFERENCES The VII ratio was more reliable than the EII ratio for describing bolus transit and distinguishing patients with NOD from asymptomatic controls, even during repeated measures of subsequent swallows.

Abstract
Background/Aims Anorectal functions are influenced by gender and age. This study sought to define the normal anorectal pressure values measured with conventional anorectal manometry (ARM) and to evaluate the effects of age and gender on anorectal function in asymptomatic subjects. Methods Conventional ARM was used to measure the anorectal pressures of 164 asymptomatic healthy subjects, including 86 males and 76 females. Results The resting anal pressures of males and females aged >60 years were significantly lower than those ≤60 years (males, 44.09±14.22 vs. 57.45±17.69, p<0.001; females, 44.09±14.22 vs. 57.45±17.69, p<0.001). The anal high-pressure zone was significantly lower in older males than in younger males (2.42±0.93 vs. 2.82±0.739, p=0.048). In both age groups (<60 and ≥60 years), the anal squeezing pressures of males were significantly higher than those of females (<60 years old, 168.40±75.94 vs. 119.15±57.53, p=0.001; ≥60 years, 149.61±64.68 vs. 101.3±54.92, p=0.006). Conclusions The normal anorectal pressure values measured with ARM in males and females were different. Older males and females had lower anal resting pressures than those of the younger subjects, but squeezing pressure was not affected by age.

Abstract
Objective Nasogastric tube (NGT) and percutaneous endoscopic gastrostomy (PEG) are widely used techniques to feed older patients with oropharyngeal dysphagia. Aspiration pneumonia is the most common cause of death in these patients. This study aimed to evaluate the role of oropharyngeal dysphagia in older patients on long-term enteral feeding for risk stratification of pneumonia requiring hospitalization. Methods We performed modified flexible endoscopic evaluation of swallowing to evaluate oropharyngeal dysphagia in older patients and conducted prospective follow-up for pneumonia requiring hospitalization. A total of 664 oral-feeding patients and 155 tube-feeding patients were enrolled. Multivariate Cox analysis was performed to identify risk factors of pneumonia requiring hospitalization. Results Multivariate analyses showed that the risk of pneumonia requiring hospitalization significantly increased in older patients and in patients with neurological disorders, tube feeding, and oropharyngeal dysphagia. Subgroup analysis revealed that the risk of pneumonia requiring hospitalization was significantly lower in patients with PEG than in those with NGT among the patients with oropharyngeal dysphagia (adjusted hazard ratio 0.26, 95% confidence interval: 0.11–0.63, P = 0.003). Conclusions For older patients with oropharyngeal dysphagia requiring long-term enteral tube feeding, PEG is a better choice than NGT. Further research is needed to elucidate the role of oropharyngeal dysphagia in enteral feeding in older patients.

Abstract
BACKGROUND Pharyngeal high-resolution manometry (HRM) has emerged over the last decade as a valuable assessment tool for oropharyngeal dysphagia. Data analysis thus far has focused primarily on measures of pressure and duration within key anatomic regions. We apply spectral arc length (SPARC), a dimensionless metric for quantifying smoothness felt to indirectly reflect neuromuscular coordination, as a new method of describing manometric curves. We then use it to distinguish swallows from healthy subjects and those with dysphagia related to stroke. METHODS Previously collected pharyngeal HRM data from eight subjects with history of stroke and eight age- and sex-matched controls were reviewed. Receiver operating characteristic (ROC) analysis was used to optimize SPARC inputs. SPARC was then computed for the velopharynx, tongue base, hypopharynx, and upper esophageal sphincter (UES), and the values were compared between the two subject groups. RESULTS Optimized parameter settings yielded an ROC curve with area under the curve (AUC) of 0.953. Mean SPARC values differed between control and stroke subjects for the velopharynx (t = 3.25, p = 0.0058), tongue base (t = 4.77, p = 0.0003), and hypopharynx (t = 2.87, p = 0.0124). Values were similar for the UES (t = 0.43, p = 0.671). CONCLUSIONS In this preliminary study, SPARC analysis was applied to distinguish control from post-stroke subjects. Considering alternative methods of analyzing pharyngeal HRM data may provide additional insight into the pathophysiology of dysphagia beyond what can be gleaned from measures of pressure and duration alone.

Abstract
Background Studies have found possible physiologic changes to esophageal motility with aging currently not taken into account in routine high-resolution manometry (HRM) interpretation. We aimed to quantify the relationship between these physiologic changes and aging to improve HRM interpretation. Methods We conducted a retrospective analysis of patients who underwent HRM at a tertiary hospital center between 2015 and 2019. Inclusion criteria were patients aged ≥18 years with normal HRM. Exclusion criteria were abnormal HRM, abnormal upper digestive endoscopy or imagery. Outcomes were median integrated relaxation pressure (IRP), lower esophageal sphincter (LES) pressure, distal contractal integral (DCI), distal latency (DL), and peristaltic break (PB) according to the v4.0 Chicago classification criteria. Effect of age was examined through univariate and multivariate linear regression analysis. Results We identified 1,917 patients with HRM and included 722 patients with normal exams (median age 56 years (interquartile range (IQR) 46 - 66), 63.8% female). Indications for HRM included dysphagia (39.6%), gastroesophageal reflux disease (29.5%), and chest pain (11.5%). There was statistically significant relationship between age and IRP (r = 0.20, P < 0.0001) as well as DCI (r = 0.12, P = 0.001) and DL (r = -0.09, P = 0.02). No statistically significant relationship was found between age and LES pressure or PB. Conclusion We found that IRP, DCI, and to a lesser extent, DL, are significantly correlated with the normal aging process in symptomatic patients. These findings should be taken into consideration when interpreting esophageal HRM.

Patterns of esophageal dysmotility elicited by multiple rapid swallows. Esophagus 2021; 18:353-361. [PMID: 33011871 DOI: 10.1007/s10388-020-00784-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Accepted: 09/18/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND High-resolution manometry (HRM) is a gastrointestinal motility diagnostic system that measures intraluminal pressures using closely aligned sensors. Multiple rapid swallows (MRS) are used in conjunction with HRM to assess esophageal physiology prior to anti-reflux and hiatal hernia procedures. METHODS A retrospective, qualitative study was conducted on 90 patients who underwent HRM with MRS in a single community clinic. 80 patients met the inclusion criteria. MRS testing consisted of rapid 2 mL swallows in 2-3 s intervals with patients in a seated, upright position. Clinical information was reviewed including indications for HRM, prior diagnostic workup, manometry, distal contractile integral (DCI), and integrated residual pressure (IRP). HRM studies were visualized using Manoview Analysis Software v3.0 (Medtronic). RESULTS Certain esophageal dysmotility and pressurization manometry patterns were previously undetected on HRM alone. In our study, the addition of MRS was clinically helpful in (1) assessing contraction reserve, (2) highlighting features of jackhammer, (3) stimulating esophageal spasm, and (4) visualizing distal esophageal pressurization pattern with mechanical obstruction. Additionally, abnormal pathophysiology such as (5) paradoxical LES contraction (achalasia) and (6) loss of deglutition inhibition were identified. MRS had a diagnostic utility of 21.25% (n = 17) among the 80 patients. An intolerance rate of 7.7% (n = 7) was observed in patients unable to complete the protocol. CONCLUSIONS Augmentation of HRM with MRS produces unique manometric features that have clinical utility in uncovering esophageal disorders. MRS provocation testing is a practical, inexpensive, well-tolerated addition to HRM that may yield useful clinical information to guide complicated diagnoses and medical management.

Abstract
BACKGROUND Jackhammer esophagus (JE) is a newly described esophageal motility disorder. However, there are limited data on JE and this entity remains misunderstood. METHODS We performed a systematic review of clinical series on JE through MEDLINE, EMBASE, and Web of Science. Data from included studies were then extracted, and random-effects meta-analyses were performed. RESULTS Thirty-eight studies met inclusion criteria. The pooled prevalence of JE was 1.97% [95% CI: 1.39%-2.78%] among patients referred for high-resolution manometry (HRM). The mean age at diagnosis was 60.8 years [95% CI: 57.1-64.4] and 65% [95% CI: 58%-72%] of patients were female. JE was significantly more prevalent in postlung transplant patients and morbidly obese patients undergoing HRM (23.99% [95% CI: 9.00%-38.97%] and 5.18% [95% CI: 1.76%-14.3%] respectively). Dysphagia was the most common presentation of JE (64% [95% CI: 52%-77%]) followed by gastroesophageal reflux disease (46% [95% CI: 26%-67%]). The pooled mean distal contractile integral (DCI) of all standard HRM swallows was 9249 mm Hg·s·cm [95% CI: 7834-10 663], and the pooled mean integrated relaxation pressure (IRP) was 13.9 mm Hg [95% CI: 8.2-19.7]. Overall, 73.6% [95% CI: 64.0%-83.1%] of JE patients who underwent treatment achieved clinical symptom improvement (79% [95% CI: 74%-85%] for endoscopic treatment and 63% [95% CI: 47%-79%] for medical treatment). The pooled clinical success rate of peroral endoscopic myotomy (POEM) specifically was 82% [95% CI: 75%-90%]. CONCLUSIONS JE is a new motility disorder most commonly presenting with dysphagia. High clinical suspicion is important because the diagnosis can only be made through HRM.

Abstract
Diseases of the esophagus, such as gastroesophageal reflux (GER), can result in changes to mucosal integrity, neurological function, and the microbiome. Although poorly understood, both age and GER can lead to changes to the enteric nervous system. In addition, the esophagus has a distinct microbiome that can be altered in GER. Mucosal integrity is also at risk due to persistent damage from acid. Diagnostic tools, such as ambulatory pH/impedance testing and esophageal mucosal impedance, can assess short-term and longitudinal GER burden, which can also assess the risk for mucosal compromise. The quality of the mucosal barrier is determined by its intercellular spaces, tight junctions, and tight junction proteins, which are represented by claudins, occludins, and adhesion molecules. Fortunately, there are protective factors for mucosal integrity that are secreted by the esophageal submucosal mucous glands and within saliva that are augmented by mastication. These protective factors have potential as therapeutic targets for GER. In this article, we aim to review diagnostic tools used to predict mucosal integrity, aging, and microbiome changes to the esophagus and esophageal mucosal defense mechanisms.

Abstract
BACKGROUND Proximal esophageal striated muscle contractility may be abnormal in patients with esophageal symptoms, but is not assessed in the Chicago Classification (CC) v3.0. We aimed to (a) determine the prevalence of abnormal proximal esophageal contractility in patients with esophageal symptoms; (b) compare proximal esophageal contractility in patients with different esophageal motility disorders; (c) assess the association of abnormal proximal esophageal contractility with esophageal symptoms. METHODS Patients undergoing high-resolution esophageal manometry (HREM) from 7/2019 to 11/2019 and healthy volunteers (HVs) were studied. Measurements of the proximal esophageal segment included the vigor of contractility of the proximal esophagus (proximal contractile integral/PCI). Patients rated gastrointestinal symptoms' severity. KEY RESULTS HREM was performed on 221 patients (63.8% females, mean age 57.1 ± 1.1 years) and 19 HVs. Mean PCI in HVs was 299.5 ± 30.6 (95% CI 32.3-566.7 mm Hg. s. cm). Of all patients, 61 (27.6%) had abnormal PCI. HVs and patients with different esophageal motility disorders had significantly different PCI (P < .01). Type 1 achalasia patients had weaker PCI than patients with absent contractility (P = .02). Patients with abnormal PCI had more severe dysphagia (P = .02), nausea (P = .03), vomiting (P = .03), and lower bolus clearance (P < .01) than patients with normal PCI. CONCLUSIONS AND INFERENCES Abnormal PCI was found in a fourth of patients with esophageal symptoms. PCI may be useful to distinguish some esophageal motility disorders. Patients with abnormal PCI had a higher severity of some upper gastrointestinal symptoms than patients with normal PCI. Assessing the proximal esophageal segment on HREM may be useful in characterizing patients with esophageal symptoms.

Abstract
INTRODUCTION AND AIMS Since the 1960s, several studies have shown the effect of aging on esophageal motility, with inconsistent results. The aim of the present study was to evaluate the manometric results in older adult patients (=60 years of age) with an esophageal disorder and compare them with adults under 60 years of age. MATERIALS AND METHODS A cross-sectional, retrospective study was conducted that included a sample of 1,175 patients (936 older adults and 239 non-older adults). The patients were evaluated and compared with respect to (i) sex, (ii) main complaint for which esophageal manometry was indicated, (iii) comorbidities, (iv) current medications, (v) smoking, and (vi) manometry results. RESULTS Patient age ranged from 19 to 92 years (women made up 76.5% of the older adults and 72.8% of the non-older adults). Normal lower esophageal sphincter relaxation and normal peristalsis were more frequent in the non-older patient group (91.1% vs. 84.8% and 87.4% vs. 76%, respectively). The manometry results for the non-older adults vs. the older adults, respectively, were: achalasia (2.9% vs. 5.9%); hypercontractile disorder (9.2% vs. 10.4%); hypocontractile disorder (38.5% vs. 47.6%); and normal values (49.4% vs. 36.1%). After excluding the variables that could change esophageal motility, the results revealed significant differences between the two study groups. CONCLUSIONS Esophageal manometry demonstrated statistically significant differences between the older adult and non-older adult study population evaluated.

Abstract
BACKGROUND Achalasia is a disease that affects esophageal bolus transit due to the absence of esophageal peristaltic contractions and impaired or absent relaxation of the lower esophageal sphincter. OBJECTIVE The objective of this investigation was: a) to evaluate the dynamics of water ingestion in patients with achalasia, idiopathic or caused by Chagas' disease; b) to evaluate the influence of sex and age on water ingestion dynamics. METHODS The investigation was conducted with 79 patients with achalasia (27 idiopathic and 52 Chagas' disease) and 91 healthy volunteers, all evaluated by the water-drinking test. The individuals drank, in triplicate, 50 mL of water without interruption. The time and the number of swallows for this task were counted. We also measured: (a) inter-swallow interval - the time to complete the task, divided by the number of swallows during the task; (b) swallowing rate - volume drunk divided by the time; (c) volume per swallow - volume drunk divided by the number of swallows. RESULTS Patients with achalasia took longer to ingest all the volume (mean 12.2 seconds) than healthy controls (mean 5.4 seconds), had greater number of swallows, longer interval between swallows, lower swallowing rate (5.2 mL/s vs 10.9 mL/s in controls) and lower volume per swallow (9.1 mL vs 14.4 mL in controls, P<0.01). Among healthy volunteers, women had a shorter interval between swallows and lower volume per swallow compared with men, and in the achalasia group, women had a longer interval between swallows and lower ingestion rate. No difference in the drinking test results was found between younger and older subjects in achalasia or control group. Also, no differences were observed between patients with Chagas' disease and those with idiopathic achalasia, or between patients with increased and normal esophageal diameter. CONCLUSION Patients with achalasia have difficulty in ingesting water, taking a longer time to complete the task, which is influenced by sex but not by age or severity of the disease.

Abstract
We undertook a systematic review of swallowing biomechanics, as assessed using pharyngeal and esophageal manometry in healthy or dysphagic older individuals aged over 60 years of age, comparing findings to studies of younger participants. PRISMA-P methodology was used to identify, select, and evaluate eligible studies. Across studies, older participants had lower upper esophageal sphincter (UES) resting pressures and evidence of decreased UES relaxation when compared to younger groups. Intrabolus pressures (IBP) above the UES were increased, demonstrating flow resistance at the UES. Pharyngeal contractility was increased and prolonged in some studies, which may be considered as an attempt to compensate for UES flow resistance. Esophageal studies show evidence of reduced contractile amplitudes in the distal esophagus, and an increased frequency of failed peristaltic events, in concert with reduced lower esophageal sphincter relaxation, in the oldest subjects. Major motility disorders occurred in similar proportions in older and young patients in most clinical studies, but some studies show increases in achalasia or spastic motility in older dysphagia and noncardiac chest pain patients. Overall, study qualities were moderate with a low likelihood of bias. There were few clinical studies specifically focused on swallowing outcomes in older patient groups and more such studies are needed.

Abstract
High-resolution esophageal manometry (HREM) has become the method of choice for evaluation of esophageal motility disorders. There is a paucity of data with this technique from Hispanic countries. This study aims to characterize the diagnostic outcome of HREM in a large cohort of consecutive patients in Mexico.This study was conducted in Monterrey, Mexico from March 1, 2013 to March 31, 2015. Our diverse study population included patients from a major academic institution and the community. HREM was done applying the Chicago Classification 3. Diagnostic outcome was grouped as weak peristaltic disorders, gastroesophageal junction disorders, and hypertensive/uncoordinated peristalsis.We studied 670 consecutive patients, 57% were women, mean age was 43.8 years. The majority (465 [69%]) were referred for preoperative evaluation of gastroesophageal reflux disease (GERD), 365 (78%) of whom had a normal study. Overall, 193 (29%) patients had abnormal motility, the most common disorder being weak peristalsis (104 [54%]). In patients with dysphagia, the most frequent finding was achalasia (23/46 [50%]).To our knowledge, this is the first study to characterize the diagnostic outcome of HREM in a large cohort of Hispanic patients in Latin America. At our open access center, 69% of patients were referred for preoperative evaluation of GERD, reflecting the popularity of antireflux surgery. This study confirms the high prevalence of weak peristalsis and highlights the importance of addressing its pathophysiology and management. The finding of achalasia in 50% of our patients with dysphagia is consistent with recent reports regarding the rising incidence of this disorder and underscores the need of prompt motility testing in this population.

Abstract
The aging-associated cellular and molecular changes in esophagus have not been established, yet. Thus we evaluated histological structure, interstitial cells of Cajal (ICCs), neuronal nitric oxide synthase (nNOS)-positive cells, and contractility in the esophagus of Fischer 344 rat at different ages (6-, 31-, 74-weeks, and 2-years). The lamina propria thickness and endomysial area were calculated. The immunoreactivity of c-Kit, nNOS and protein gene product (PGP) 9.5 was counted after immunohistochemistry. Expression of c-Kit, stem cell factor (SCF), nNOS and PGP 9.5 mRNA was measured by real-time PCR, and expression of c-Kit and nNOS protein was detected by Western blot. Isovolumetric contractile force measurement and electrical field stimulation (EFS) were conducted. The lamina propria thickness increased (6 week vs 2 year, P = 0.005) and the endomysial area of longitudinal muscle decreased with aging (6 week vs 2 year, P<0.001), while endomysial area of circular muscle did not significantly decrease. The proportions of NOS-immunoreactive cells and c-Kit-immunoreactive areas declined with aging (6 week vs 2 year; P<0.001 and P = 0.004, respectively), but there was no significant change of PGP 9.5-immunopositiviy. The expressions of nNOS, c-Kit and SCF mRNA also reduced with aging (6 week vs 2 year; P = 0.006, P = 0.001 and P = 0.006, respectively), while the change of PGP 9.5 mRNA expression was not significant. Western blot showed the significant decreases of nNOS and c-Kit protein expression with aging (6 week vs 2 year; P = 0.008 and P = 0.012, respectively). The EFS-induced esophageal contractions significantly decreased in 2-yr-old rat compared with 6-wk-old rats, however, L-NG-Nitroarginine methylester did not significantly increase the spontaneous and EFS-induced contractions in the 6-wk- and 2-yr-old rat esophagus. In conclusion, an increase of lamina propria thickness, a decrease of endomysial area, c-Kit, SCF and NOS expression with preserved total enteric neurons, and contractility in aged rat esophagus may explain the aging-associated esophageal dysmotility.
