Li M, Gao N, Wang S, Guo Y, Liu Z. A global bibliometric and visualized analysis of the status and trends of gastroparesis research. Eur J Med Res 2023; 28:543. [PMID: 38017518 PMCID: PMC10683151 DOI: 10.1186/s40001-023-01537-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2022] [Accepted: 11/17/2023] [Indexed: 11/30/2023] Open
Abstract
BACKGROUND Gastroparesis has a substantial impact on the quality of life but has limited treatment options, which makes it a public health concern. No bibliometric studies on gastroparesis have been published thus far. Thus, this article aims to summarize and analyze research hotspots to provide a reference for clinical researchers. MATERIALS AND METHODS Gastroparesis-related research articles were searched in the Web of Science Core Collection (WOSCC), and relevant information was extracted after screening. A total of 1033 documents were analyzed with the bibliometric method using Microsoft Excel, Citespace, and VOSviewer. RESULTS Overall, our search retrieved 1033 papers contributed by 966 research institutions from 53 countries. Since 1980, publications in this field have increased rapidly. United States (n = 645) and Temple University (n = 122) were the most productive country and institution, respectively. Parkman, with 96 publications, was the most prominent author. CONCLUSIONS Research hotspots in gastroparesis can be summarized into four domains: innovation in diagnostic modalities, change of oral therapeutic agents, choice of surgical interventions, and pathological mechanisms. Future research on gastroparesis should focus on the quality of life of patients, diagnostic techniques, pyloromyotomy, and transpyloric stent placement.

[PMID: 36377810 DOI: 10.1111/nmo.14499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 10/18/2022] [Accepted: 11/07/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Peripheral corticotropin-releasing factor (CRF) has been reported to affect gastrointestinal motility through corticotropin-releasing factor receptor located in enteric nervous system (ENS), but less is known about of the relationship between peripheral CRF and interstitial cells of Cajal (ICC). METHODS Mice were intraperitoneally injected with CRF receptor agonists to determine their effects on colonic ICC. Chronic heterotypic stress (CHeS) was applied to mice to determine endogenous CRF-CRF receptor signaling on colonic ICC. RESULTS We found that stressin1, a selective CRF receptor 1 (CRF1 ) agonist, significantly increased the expression of CRF1 but had no effect on the expression of CRF2 in the smooth muscles of murine colon. The protein expression of c-Kit, Anoctamin-1 (ANO1), and stem cell factor (SCF) in the colonic smooth muscles was significantly decreased in stressin1-treated mice. Accordingly, 2-(4-Chloro-2-methylphenoxy)-N'-(2-methoxybenzylidene) acetohydrazide (Ani 9), a selective ANO1 blocker, had a less significant inhibitory effect on CMMC in stressin1-treated mice compared to the saline-treated ones. Similarly, we also found that ICC and ANO1 were reduced in the colonic smooth muscles of mice by treatment with sauvagine (ip), a CRF2 agonist. However, different with stressin1, sauvagine decreased the expression of CRF2 besides increasing CRF1 expression in the colonic smooth muscles. Similar results of CRF1 and c-Kit expressions were also obtained from the colon of CHeS-treated mice. CONCLUSION All these results suggest that CRF may be involved in the abnormality of colonic motility through peripheral CRF1 to decrease the number and function of ICC, which provides a potential target for treating stress-induced gastrointestinal motility disorder.

United European Gastroenterol J 2022; 10:888-897. [PMID: 35985672 PMCID: PMC9557951 DOI: 10.1002/ueg2.12289] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 07/30/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND/OBJECTIVES The global epidemiology of gastroparesis is unknown. The European UEG and European Society for Neurogastroenterology and motility consensus defines Gastroparesis as a condition characterized by delayed gastric emptying in the absence of mechanical obstruction, with a symptom pattern of nausea and/or vomiting and overlapping postprandial distress syndrome (PDS). Real-world evidence of this gastroparesis-like symptom pattern is a crucial step in understanding the epidemiology of gastroparesis. METHODS In the Rome Foundation Global Epidemiology Study, 54,127 respondents from 26 countries completed the Rome IV Diagnostic Questionnaire and variables associated with disorders of gut-brain interaction via Internet. We selected subjects with gastroparesis-like symptoms (GPLS) (nausea and/or vomiting ≥1 day/week and simultaneous PDS). Patients reporting organic gastrointestinal disease, or fulfilling criteria for self-induced vomiting, cyclic vomiting or cannabinoid hyperemesis syndrome were excluded. We determined prevalence, associated comorbidities, quality of life (QoL) (PROMIS Global-10), symptoms of anxiety and depression (PHQ-4), somatic symptoms (PHQ-12), and healthcare utilization. RESULTS The global prevalence of GPLS was 0.9% overall and 1.3% among diabetic individuals. Subjects with GPLS showed frequent overlapping of epigastric pain syndrome and irritable bowel syndrome. Subjects with GPLS had significantly lower body mass index, QoL, more non-gastrointestinal somatic complaints, symptoms of anxiety and depression, higher medication usage and doctor visits in the overall and diabetic population, compared to subjects without these symptoms. CONCLUSIONS GPLS are common worldwide and more common in diabetic patients. The symptom complex is associated with multiple aspects of illness and an increased healthcare consumption.

Abstract
Abdominal pain is a common complaint in the emergency department, comprising 8.8% of all visits. Despite advances in medicine and imaging, 20% to 30% of patients still leave the department without a definitive diagnosis, whichhis can be both distressing for patients and unsatisfying for providers. Diagnoses of exclusion can be perilous, and their application should be carefully considered in order to not overlook more emergent complaints. However, a working knowledge of diagnoses of exclusion can guide therapeutics and specialty referrals that can ultimately provide answers and relief to a patient population often at odds with available information and expectations.

Abstract
We present and discuss a late-nineteenth century clinical case described by Professor Taruffi in a scientific paper titled "Scheletro con prosopoectasia e tredici vertebre dorsali" (Skeleton with prosopoectasia and thirteen thoracic vertebrae). Taruffi could not explain the disproportionate skeletal and visceral growth, and the case could therefore be considered an unrecognized case of acromegaly. The anatomopathological specimens and the wax model cited in the paper are currently hosted at the "Luigi Cattaneo" Anatomical Wax Collection of Bologna University; however, some inaccuracies and uncertainties as to their attribution to the same case have remained to this day. The skeletal remains were examined macroscopically to investigate any structural abnormalities and pathological changes. In addition, thanks to archival, museum inventory and literature research, we documented the systematic relationship between the paper and the samples and were able to ascribe the abnormally dilated dried stomach, currently displayed in a different showcase, to the same case. This is, to our knowledge, the first case of acromegaly in the history of medical literature which also includes a visceral specimen. As far as we know, there are no reports of the occurrence of severe gastromegaly in patients with acromegaly. In view of this rare association and, to date, endocrinological research, we hypothesize a further pathogenic mechanism by which acromegaly could have induced this massive dilatation. Taruffi's work represents an immensely valuable scientific/artistic heritage and is still cited in contemporary endocrinological literature, demonstrating its relevant contribution to the historical evolution of the disease through the nineteenth and twentieth centuries.

Abstract
Patients with gastroparesis often have signs and symptoms including nausea, vomiting, epigastric discomfort, and early satiety, thus leading to inadequate food intake and a high risk of malnutrition. There is a considerable scarcity of data about nutritional strategies for gastroparesis, and current practices rely on extrapolated evidence. Some approaches include the modification of food composition, food consistency, and food volume in the context of delayed gastric emptying. If the patient is unable to consume adequate calories through a solid food diet, stepwise nutritional interventions could include the use of liquid meals, oral nutrition supplements, enteral nutrition, and parenteral nutrition. This Review discusses the role, rationale, and current evidence of diverse nutritional interventions in the management of gastroparesis.

Abstract
BACKGROUND The Motilis 3D-Transit system allows ambulatory description of transit patterns throughout the gastrointestinal tract and offers an alternative method for studying gastric motility. We aimed to establish normative values for gastric motility assessed with the method. METHOD A total of 132 healthy volunteers ingested the 3D-Transit capsule for assessment of gastrointestinal transit times. Recordings from 125 subjects were used for definition of normative values. Forty-six subjects were studied on two consecutive days. Recordings were reanalyzed using newly developed software providing information on gastric emptying (GE) as well as contraction frequency and movement during gastric contractions. RESULTS The median GE time was 2.7 hours (range 0.1-21.2). In 89% of subjects, the capsule passed the pylorus within a postingestion period of 6 hours. The median frequency of gastric contractions was 3.1 per minute (range 2.6-3.8). The frequency was higher in women (3.2, range 2.7-3.8) than in men (3.0, range 2.6-3.5) and increased with age (0.004 per year) (P < .05). The median amplitudes were 35° (range 4-85) when based on rotation of the capsule and 11 mm (range 6-31) when based on capsule change in position. The rotation amplitude was higher in women and decreased with increasing BMI (P < .05). The position amplitude was also higher in women and increased with the amount of calories in the test meal, but decreased with increasing BMI and age (P < .05). Day-to-day variation (P > .05) was considerable while inter-rater variability was small. CONCLUSION AND INFERENCES We have established normative values for gastric motility assessed with the 3D-Transit system.

Electroacupuncture Relieves Suppression of Autophagy in Interstitial Cells of Cajal of Diabetic Gastroparesis Rats. Can J Gastroenterol Hepatol 2020; 2020:7920715. [PMID: 32211350 PMCID: PMC7060882 DOI: 10.1155/2020/7920715] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Revised: 01/13/2020] [Accepted: 01/16/2020] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND The incidence of diabetic gastroparesis (DGP) is mainly blamed to abnormity of interstitial cells of Cajal (ICCs). Autophagy could degrade damaged proteins and organelles to keep intracellular homeostasis, and it could directly influence structure and number of cells. In this study, we aimed to figure out the relationship between DGP and autophagy of ICCs. METHODS Sixty Sprague-Dawley (SD) rats were randomly divided into normal control group (NC, 10) and modeling group (50). Rats in the modeling group were injected 2% streptozotocin (STZ) and fed with high-glucose and high-fat diet for 8 weeks in order to establish DGP rat model. After modeling, 30 successfully modeled rats were randomly selected and separated into diabetic gastroparesis group (DGP, 10), GDP rats with electroacupuncture group (EA, 10), and GDP rats with metoclopramide group (MP, 10). When the intervention was completed, blood glucose was measured by ONE TOUCH glucometer and gastrointestinal propulsive rate was detected through measuring optical density. Autophagosomes were observed under transmission electron microscope (TEM). The expression of LC3 protein and P62 protein was measured by Western blot. When ICCs were transfected with GFP-RFP-LC3 plasmid, autophagy flux was observed by laser scanning confocal microscope. RESULTS (1) After intervention, compared with blood glucose of rats in the NC group, all of the DGP, EA, and MP groups were remarkably increased (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01); compared with the DGP group, the blood glucose of the EA and MP groups was decreased greatly (P < 0.01). (2) Compared with gastrointestinal propulsive rate of rats in the NC group, no matter gastric emptying rate or intestinal propulsive rate, the EA and MP groups were significantly reduced (P < 0.01); compared with the NC group, gastric emptying rate and intestinal propulsive rate in the EA group were obviously decreased (P < 0.05, P < 0.01); compared with the DGP group, the EA and MP groups were increased significantly (P < 0.01). (3) Compared with the NC group, intensity of RFP and GFP in the DGP group was obviously increased (P < 0.05, P < 0.01), in other words, the DGP group accompanying suppression of autophagy; compared with the DGP group, intensity of RFP and GFP in the EA group was decreased significantly (P < 0.05, P < 0.01). (4) There was no autophagosome in the NC group, and an autophagosome existed in the DGP group. Both EA and MP groups found autophagy. (5) When coming to LC3 II/LC3 I, compared with the NC group, the ratio was enhanced in the DGP and EA groups (P < 0.01, P < 0.05); compared with the DGP group, LC3 II/LC3 I was dramatically decreased in the MP and EA groups (P < 0.01). (6) As the substrate of degradation, the expression of P62 in the other three groups was significantly increased (P < 0.01) compared with the NC group; compared with the DGP group, the amount of P62 in the EA and MP groups was reduced greatly (P < 0.01). CONCLUSION The impaired autophagy flux in ICCs is the pathological basis of diabetic gastroparesis, blaming to fusion dysfunction of autophagosome and lysosome and electroacupuncture (EA) could ease the suppression of autophagy to improve gastric motility.

Abstract
Gastroparesis is defined as a delay in gastric emptying in the absence of mechanical obstruction in the stomach. Gastroparesis has a number of causes, including postsurgical, secondary to medications, postinfectious, idiopathic, and as a complication of diabetes mellitus, where it is underrecognized. The cardinal symptoms of diabetic gastroparesis are nausea, early satiety, bloating, and vomiting. Diabetic gastroparesis is more common in females and has a cumulative incidence of 5% in type 1 diabetes and 1% in type 2 diabetes. It is associated with a reduction in quality of life and exerts a significant burden on health care resources. The pathophysiology of this disorder is incompletely understood. Diagnosis is made based on typical symptoms associated with the demonstration of delayed gastric emptying in the absence of gastric outlet obstruction. Gastric emptying scintigraphy is the gold standard for demonstrating delayed gastric emptying, but other methods exist including breath testing and the wireless motility capsule. Diabetic gastroparesis should be managed within a specialist multidisciplinary team, and general aspects involve dietary manipulations/nutritional support, pharmacological therapy, and surgical/endoscopic interventions. Specific pharmacological therapies include prokinetics and antiemetics, with several new medications in the drug development pipeline. Surgical/endoscopic interventions include botulinum toxin injection into the pylorus, gastric peroral endoscopic myotomy and gastric electrical stimulation. This article provides a detailed review and summary of the epidemiology, pathophysiology, investigation, and management of diabetic gastroparesis, and also gives an individual patient's perspective of living with this disabling disorder.

[PMID: 30947400 PMCID: PMC6850664 DOI: 10.1111/nmo.13588] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 02/14/2019] [Accepted: 03/11/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND Gastroparesis is characterized by abnormal gastric motor function with delayed gastric emptying in the absence of mechanical obstruction. In our tertiary referral center, patients are treated with a stepwise approach, starting with dietary advice and prokinetics, followed by three months of nasoduodenal tube feeding with "gastric rest." When not successful, a percutaneous endoscopic gastrostomy with jejunal extension (PEG-J) for long-term enteral feeding is placed. AIM To evaluate the effect of this stepwise approach on weight and symptoms. METHODS Analyses of data of all referred gastroparesis patients between 2008 and 2016. KEY RESULTS A total of 86 patients (71% female, 20-87 years [mean 55.8 years]) were analyzed of whom 50 (58%) had adequate symptom responses to diet and prokinetics. The remaining 36 (decompensated gastroparesis) were treated with three months gastric rest. Symptom response rate was 47% (17/36). Significant weight gain was seen in all patients, independent of symptom response. In the remaining 19 symptom non-responders, the enteral feeding was continued through PEG-J. Treatment was effective (symptoms) in 37%, with significant weight gain in all. In 84% of patients, the PEG-J is still in use (mean duration 962 days). CONCLUSIONS AND INFERENCES Following a stepwise treatment approach in gastroparesis, adequate symptom response was reached in 86% of all patients. Weight gain was achieved in all patients, independent of symptom response. Diet and prokinetics were effective with regard to symptoms in 58%, temporary gastric rest in 47%, and PEG-J as third step in 37% of patients.

Immunosuppressive drugs and the gastrointestinal tract in renal transplant patients. Transplant Rev (Orlando) 2018; 33:55-63.

Abstract
Gastrointestinal (GI) discomfort is common after renal transplantation and can be caused by the use of various immunosuppressive drugs. GI symptoms affect the quality of life, lead to an impaired graft survival and an increased mortality. Moreover, diseases and disturbances of the GI tract also affect the pharmacokinetics of immunosuppressive drugs. This review addresses the interaction between immunosuppressive agents and GI disorders. The GI tract is involved in the metabolism of several immunosuppressive drugs. Calcineurin inhibitors, mTor inhibitors, and corticosteroids are subjected to metabolism by the intestinal cytochrome P450 (CYP3A) and by the drug efflux pump ABCB1. Mycophenolate is partly metabolized in the stomach and intestine and undergoes enterohepatic recirculation. Gastrointestinal disturbances can lead to a modified exposure to immunosuppressive drugs. In the first and second part of this review, we focus on the role of the GI tract in the pharmacokinetics of the immunosuppressive drugs and how to adjust immunosuppressive therapy in patients with vomiting, need for tube feeding, delayed gastric emptying, intestinal resection, and diarrhea. In the third part, we review the GI adverse effects of the various immunosuppressive drugs, with special attention for diarrhea and dyspepsia. Finally, we discuss the effects of drugs used for relief of GI complaints on the exposure to immunosuppressive agents.

Abstract
Video capsule endoscopy (VCE) has been applied in the last 15 years in an increasing field of applications. Although many contraindications have been put into perspective, some precautions still have to be considered. Known stenosis of the gastrointestinal tract is a clear contraindication for VCE unless surgery is already scheduled or at least has been considered as an optional treatment modality. In patients with a higher incidence of stenosis, as in an established diagnosis of Crohn’s disease, clinical signs of obstruction, prior radiation or surgical small bowel resection, a preceding test with the self-dissolving patency capsule can override this contraindication. Endoscopic placement of the capsule should be considered in patients with swallowing disorders to avoid aspiration. Esophageal or gastric motility disorders may require endoscopic capsule transport or application of prokinetics if the real-time viewer proofs delayed transit. In pregnant women, VCE should be restricted to urgent cases where diagnosis cannot be postponed after delivery, as data on safety are missing. There is theoretical and clinical evidence that patients with implanted cardiac devices such as a pacemaker, cardioverters or left heart assist devices, can safely undergo VCE in spite of still existing contraindication by manufacturers. Children from the age of 2 years have safely undergone VCE. Although video capsules are not proven safe with magnetic resonance imaging (MRI), first single cases of patients incidentally undergoing MRI with an incorporated capsule have been reported, showing susceptibility artifacts but no signs of clinical harm.

Abstract
INTRODUCTION Gastroparesis, or delayed gastric emptying, can be diagnosed with gastric emptying scintigraphy. Manometric studies of patients with gastroparesis show increased pyloric tone (pylorospasm). Among the recent endoscopic therapies for pylorospasm is peroral endoscopic pylorotomy (POP). In this study, we explored the effect of POP on gastric emptying in healthy pigs. MATERIAL AND METHODS Four mini-pigs underwent POP following general anaesthesia. The mucosal entrance was situated 5 cm above the pylorus. POP was performed through a submucosal tunnel dissection. The duration of gastric emptying was assessed by scintigraphy before and after the procedure. The pigs were then euthanised for necropsy and pathologic assessment of the pylorus. RESULTS The mean duration of the procedure was 55 (± 4 SD) min. All surgeries were performed in their entirety with 100 % feasibility. There were no cases of bleeding. The one case of perforation had no clinical significance. The duration of gastric emptying was 2.22-fold shorter after POP compared with before POP (T½ post-POP = 84.5 [± 35.7 SD] min vs. T½ pre-POP = 188.4 [± 87.3 SD] min; P = 0.029). In agreement with the endoscopic observations, sectioning of the pyloric muscle in each pig was histologically complete. CONCLUSION The efficacy of the procedure provides indirect proof of the involvement of the pyloric ring in delayed gastric emptying and suggests new therapies for patients with gastroparesis. Our protocol combining gastric emptying scintigraphy and POP validated the use of anaesthetised mini-pigs as a learning and training model for POP or other endoscopic/surgical procedures related to gastric emptying.

Abstract
BACKGROUND Gastroparesis is a motility disorder of the stomach. The symptoms are non-specific: nausea and vomiting are most common. Stomach pains, early satiety, postprandial fullness and bloating are also frequent symptoms. Current diagnostic criteria require delayed gastric emptying in the absence of any detectable mechanical obstruction. In this review article we elucidate the causes, assessment and treatment options.MATERIAL AND METHOD Structured article search in Embase and PubMed.RESULTS A number of conditions can lead to gastroparesis. The most frequent somatic cause is diabetes mellitus. Gastroparesis may also be iatrogenically inflicted by means of surgery or drugs. It may be difficult to discriminate between functional dyspepsia and idiopathic gastroparesis. Examination is based on patient history, gastroscopy and measurement of the rate of gastric emptying. Biochemical tests are also relevant for differential diagnosis. The treatment is primarily symptomatic, and consists of dietary measures, fluid therapy, drugs, gastric electrical stimulation, or endoscopic or surgical intervention in the form of insertion of a feeding tube for nutrition and abdominal relief, pyloroplasty or gastrectomy.INTERPRETATION Gastroparesis is a serious motility disorder. The condition may have significant consequences for patients, entailing reduced quality of life, reduced workforce participation and a considerable need for health assistance.

Abstract
Gastroparesis (GP) is a chronic debilitating dysmotility characterized by unrelenting nausea, vomiting, bloating, early satiety, postprandial fullness and abdominal pain. Patients with GP experience other associated conditions, including gastroesophageal reflux disease, gastric bezoars and small bowel bacterial overgrowth. Furthermore, GP is associated with poor quality of life, increased emergency room visits, hospitalizations and subsequent increased healthcare costs. Currently, the managements of GP consist of glycemic control, antiemetics, prokinetics and the use of gastric electrical stimulation. However, most GP patients are at risk for significant nutritional abnormalities. As such, it is essential to screen and diagnose malnutrition in these patients. Poor oral intake in such patients could be supplemented by enteral tube feeding. Parenteral nutrition, although a last resort, is associated with a number of complications and should be used only for the short term. In summary, a systematic approach including initial nutritional screening, diet recommendations, medical therapy, nutritional re-evaluation and enteral and parental nutrition should be considered in complex GP patients.

Abstract
BACKGROUND AND PURPOSE Here we have investigated the pharmacokinetics, pharmacodynamics and safety of single doses of camicinal in type 1 diabetes mellitus (T1DM) patients with a history of slow gastric emptying with symptoms consistent with gastroparesis. EXPERIMENTAL APPROACH In a randomized, double-blind, placebo-controlled, incomplete block, three-period, two-centre crossover study, patients received oral administration of placebo and two of the three possible doses of camicinal (25, 50 or 125 mg). Gastric emptying ((13) C-octanoic acid breath test), pharmacokinetics and safety were primary outcomes. KEY RESULTS Nine of the 10 patients enrolled completed the study. Gastric half-emptying time decreased by -95 min (95% CI: -156.8, -34.2) after a single dose of camicinal 125 mg compared with placebo (52 vs. 147 min, P < 0.05), representing a 65% improvement. A decrease of the gastric half-emptying time compared with placebo (approximately 39 min) was observed with camicinal 25 and 50 mg, representing a 27% reduction for both doses (not statistically significant). A positive exposure-response relationship was demonstrated across all doses. The effects of camicinal on gastric half-emptying time were not influenced by fasting glucose levels. Single doses up to 125 mg were well tolerated. Camicinal was well absorbed, exhibiting linear and approximately dose-proportional pharmacokinetic characteristics and a clear exposure-response relationship with gastric emptying. CONCLUSIONS AND IMPLICATIONS Camicinal significantly accelerated gastric emptying of solids in T1DM patients following administration of a single oral dose. Camicinal was well tolerated and exhibited similar pharmacokinetic characteristics in diabetic patients to those previously reported in healthy volunteers.

Abstract
BACKGROUND Patients with gastrointestinal (GI) dysmotility often experience overlapping upper and lower GI symptoms suggestive of multiregional involvement. Wireless motility capsule (WMC) provides a full GI tract transit profile and may be able to detect and diagnose multiregional dysmotility. AIM To determine the clinical utility and diagnostic yield of WMC in patients with upper and lower GI symptoms suggestive of multiregional GI dysmotility. METHODS Retrospective chart review of all patients who had undergone WMC testing for suspected multiregional GI dysmotility from January 2009 to December 2012 at our institution was performed. Information regarding demographics, symptoms, medication use, prior diagnostic studies, and results of WMC testing was collected. RESULTS A total of 161 patients were included in the analysis. Mean age was 43 ± 15 years, and 83 % were female. WMC was abnormal in 109 (67.7 %) subjects. Of these, 17 (15.6 %) patients had isolated delayed gastric emptying, 13 (11.9 %) patients had isolated delayed small bowel transit, and 25 (22.9 %) patients had isolated delayed large bowel transit. Multiregional dysmotility was diagnosed in 54 (49.5 %) patients. There was no significant difference in past medical or past surgical history between patients with isolated regional versus multiregional involvement. The presence or absence of various patient-reported symptoms by history did not predict an abnormal WMC study. CONCLUSIONS Patients' symptoms are poor predictors of GI dysmotility and its anatomical extent. WMC can be a useful diagnostic test in these patients as it provides a comprehensive evaluation of the motility profile of the entire GI tract and provides objective evidence of multiregional involvement.

Abstract
Obesity is a major health problem worldwide. The prevalence of obesity is increasing in both developed and developing countries. In the UK, for example, 60% of adults are overweight and 25% are obese. Obesity is associated with many pathological complications including respiratory, cardiovascular and endocrine, but it also affects fertility and is associated with many reproductive complications. This has led us and others to investigate links between women with high BMI, pregnancy outcome and uterine function. These studies in turn have led investigators to ask how obesity can have such an impact on reproduction and, as part of this, to consider the role of the adipokines released from adipose tissues. Our focus in this short review is on adipokines and myometrial activity, and for completeness we overview their effects on other smooth muscles. To date four adipokines (leptin, visfatin, apelin and ghrelin) have been investigated and all affect myometrial contractility, but some more potently than others. We consider the possible mechanisms involved in how adipokines may modify uterine contractility, and discuss the potential impact on labor and delivery.

Abstract
OPINION STATEMENT The careful review of drug-drug interactions is vital to the safe prescribing of medications for chronic medical conditions. The elderly population suffers from multiple medical problems, and polypharmacy leads to further morbidity in this vulnerable group of patients. We discuss gastrointestinal conditions such as GERD, peptic ulcer disease, gastroparesis, diarrhea, constipation, irritable bowel syndrome, inflammatory bowel disease, chronic liver disease and the commonly used medications in these conditions. Treatment options must be individualized and tailored to accommodate the underlying pharmacokinetics and known drug-drug interactions. The indication for the use of a therapeutic agent in the elderly and the duration of use must be frequently readdressed to help prevent polypharmacy and adverse drug reactions. Medications should be started at a low dose with careful titration to achieve a clinical response to prevent toxicity. The aim of this article is to increase awareness of important drug-drug interactions of commonly prescribed gastrointestinal medications in the elderly.

Abstract
Advances in surgery, anesthesia and intensive care have led to a dramatic increase in the number of patients who spend time in our intensive care units (ICU). Gastrointestinal (GI) motility disorders are common complications in the intensive care setting and are predictors of increased mortality and length of the stay in the ICU. Several risk factors for developing GI motility problems in the ICU setting have been identified and include sepsis, being on mechanical ventilation and the use of vasopressors, opioids or anticholinergic medications. Our focus is on the most common clinical manifestations of GI motor dysfunction in the ICU patient: gastroesophageal reflux, gastroparesis, ileus and acute pseudo-obstruction of the colon.

Abstract
BACKGROUND The histopathology of the gastric mucosa in patients with gastroparesis, a condition characterized by gastric retention without obstruction, has not been described. AIM To test the hypothesis that reactive gastropathy is more common in patients with gastroparesis than in subjects with normal gastric motility. METHODS We compared the prevalence of reactive gastropathy, Helicobacter pylori infection, chronic gastritis, and intestinal metaplasia in patients with and without a clinical diagnosis of gastroparesis extracted from a national database of subjects with gastric biopsies (1/2008-6/2012). RESULTS There were 3040 patients with gastroparesis (median age 58 years, 67.3% women) and 575,895 controls (median age 57 years, 62.0% women) with no evidence of gastroparesis. Reactive gastropathy was marginally more prevalent in patients with gastroparesis (18.9%) than in controls (17.0%). In contrast, H. pylori gastritis was present in 10.8% of controls, but only in 5.9% patients with gastroparesis (OR 0.52; 95% CI 0.45-0.61). Intestinal metaplasia was also less common in patients with gastroparesis (2.8% versus 3.9%; OR 0.82; 95% CI 0.58-0.89). CONCLUSIONS The low prevalence of H. pylori infection in gastroparesis could be explained by higher rates of previous eradication, conditions unfavourable to the survival of H. pylori, or a protective effect of mucosal inflammation against the development of motility disorders.

Abstract
Nausea and vomiting are common gastrointestinal complaints which could be triggered by stimuli in both the peripheral and central nervous systems. They may be considered as defense mechanisms when threatening toxins/agents enter the gastrointestinal tract or there is excessive retention of gastrointestinal contents due to obstruction. The pathophysiology of nausea and vomiting is complex and much still remains unknown. Therefore, treatments are restricted or ineffective in many cases. Nausea and vomiting with functional etiologies including cyclic vomiting syndrome are challenging in gastroenterology. In this article, we review potential pathways, neurochemical transmitters, and their receptors which are possibly involved in the pathophysiology of nausea and vomiting including the entity cyclic vomiting syndrome.

Abstract
Diabetes mellitus affects virtually every organ system in the body and the degree of organ involvement depends on the duration and severity of the disease, and other co-morbidities. Gastrointestinal (GI) involvement can present with esophageal dysmotility, gastro-esophageal reflux disease (GERD), gastroparesis, enteropathy, non alcoholic fatty liver disease (NAFLD) and glycogenic hepatopathy. Severity of GERD is inversely related to glycemic control and management is with prokinetics and proton pump inhibitors. Diabetic gastroparesis manifests as early satiety, bloating, vomiting, abdominal pain and erratic glycemic control. Gastric emptying scintigraphy is considered the gold standard test for diagnosis. Management includes dietary modifications, maintaining euglycemia, prokinetics, endoscopic and surgical treatments. Diabetic enteropathy is also common and management involves glycemic control and symptomatic measures. NAFLD is considered a hepatic manifestation of metabolic syndrome and treatment is mainly lifestyle measures, with diabetes and dyslipidemia management when coexistent. Glycogenic hepatopathy is a manifestation of poorly controlled type 1 diabetes and is managed by prompt insulin treatment. Though GI complications of diabetes are relatively common, awareness about its manifestations and treatment options are low among physicians. Optimal management of GI complications is important for appropriate metabolic control of diabetes and improvement in quality of life of the patient. This review is an update on the GI complications of diabetes, their pathophysiology, diagnostic evaluation and management.

Abstract
In recent years, it has become possible to record, from a large number of extracellular electrodes, the electrical activities of smooth muscle organs. These recordings, after proper processing and analysis, may reveal origin and propagation of normal and abnormal electrical activities in these organs. Several publications have appeared in the past 5 years describing origin and propagation of slow waves in the stomach of experimental animals and in humans. Furthermore, publications are now starting to appear that describe pathophysiological patterns of propagation and these studies provide us with novel concepts regarding potential mechanisms of arrhythmias in the gut, crucial information if we are ever going to successfully treat patients suffering from such arrhythmias. In this issue of Neurogastroenterology & Motility, Angeli et al. have mapped the slow wave propagation in the porcine small intestine and discovered two types of reentry; functional reentry and circumferential reentry. Next to the descriptions of arrhythmias in the stomach, the fact that reentrant arrhythmias may also occur in the small intestine further extends this new emerging field of gastrointestinal (GI) arrhythmias. In this viewpoint, the relevance of these arrhythmias is further discussed and a few ideas for future research in this field, not necessarily constrained to the GI system, proposed.
