Comparative Analysis of Relaxation Time Interval and Integrated Relaxation Pressure as Risk Factors for Aspiration in Patients With Oropharyngeal Dysphagia. J Neurogastroenterol Motil 2021; 27:518-524. [PMID: 34642271 PMCID: PMC8521479 DOI: 10.5056/jnm20049] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 01/14/2021] [Accepted: 04/23/2021] [Indexed: 11/20/2022] Open
Abstract
Background/Aims Integrated relaxation pressure (IRP) is an important metric for functional evaluation of the lower esophageal sphincter. However, the effectiveness of IRP for evaluation of upper esophageal sphincter (UES) function has not yet been clarified. Methods High-resolution manometry (HRM) was performed in 180 patients with dysphagia. For comparison, 26 asymptomatic subjects were also recruited. IRP of the UES was defined as means of 0.2, 0.25, or 0.3 seconds (sIRPs) of maximal deglutitive relaxation in a 0.4-second window (a new equation for IRP calculation was developed using MATLAB). Also, the relaxation time interval of the UES, and mesopharyngeal and hypopharyngeal contractility (as a contractile integral) were evaluated using HRM. Results In normal subjects, mean values of 0.2, 0.25, and 0.3 sIRPs differed significantly from each other (P < 0.05). They were not associated with the relaxation time interval of the UES. In contrast, in patients with dysphagia, mean values of 0.2, 0.25, and 0.3 sIRPs were strongly related to relaxation time intervals of the UES (P < 0.05), and mean values of 0.2, 0.25, and 0.3 sIRPs in patients with aspiration were significantly higher than those of patients without aspiration (P < 0.01). However, in multivariate regression analyses, the main risk factor for aspiration was only a shorter relaxation time interval. Conclusions IRP values were significantly higher in patients with dysphagia and aspiration. However, its usefulness as a predictive factor for aspiration was less than the relaxation time interval of the UES.

Weight loss and waist reduction is associated with improvement in gastroesophageal disease reflux symptoms: A longitudinal study of 15 295 subjects undergoing health checkups. Neurogastroenterol Motil 2017; 29. [PMID: 28002892 DOI: 10.1111/nmo.13009] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2016] [Accepted: 11/16/2016] [Indexed: 02/08/2023]
Abstract
BACKGROUND General obesity and abdominal obesity is an established risk factor of gastroesophageal reflux disease (GERD). However, the influence of weight or waist change on improvement of GERD is unclear. Our aim was to investigate if weight loss or waist reduction improves GERD symptoms and esophagitis. METHODS A retrospective longitudinal study of 15 295 subjects who underwent gastroscopy for a health checkup and reported GERD symptoms between 2011 and 2013, and repeated a checkup until 2014 was conducted. The improvement of GERD symptoms and esophagitis according to weight loss (≥-2, -0.5 to -2 kg/m2 in body mass index [BMI]), waist reduction (≥-5, -0.1 to -0.5 cm) and baseline BMI/waist circumference (WC) categories was assessed using logistic regression. KEY RESULTS Weight loss or waist reduction was associated with improvement in GERD symptoms only in subjects with general or abdominal obesity. Among subjects with general obesity (BMI ≥25 kg/m2 ) and decreased ≥2 kg/m2 in BMI, the adjusted odds ratio (OR) of improvement in GERD symptoms was 2.34 (95% confidence interval [CI] 1.70-2.83). Among subjects with abdominal obesity (WC ≥90 cm) and decreased ≥5 cm in WC, the corresponding OR was 2.16 (95% CI 1.56-2.90). There was no association between weight loss or waist reduction and improvement in esophagitis. CONCLUSIONS & INFERENCES Weight loss or waist reduction was associated with improvement in GERD symptoms only in subjects with general or abdominal obesity. Weight loss or waist reduction will be an important treatment option in obese patients.

Recurrence and Its Impact on the Health-related Quality of Life in Patients with Gastroesophageal Reflux Disease: A Prospective Follow-up Analysis. J Neurogastroenterol Motil 2015; 22:86-93. [PMID: 26486229 PMCID: PMC4699725 DOI: 10.5056/jnm15124] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2015] [Revised: 09/03/2015] [Accepted: 09/07/2015] [Indexed: 12/13/2022] Open
Abstract
Background/Aims Limited data exist on the outcome of gastroesophageal reflux disease (GERD) treatment and its impact on the health-related quality of life (HRQoL) in the Asian population. This study aims to evaluate the treatment outcomes, to investigate the factors associated with recurrence, and to evaluate the impact of the treatment outcome on the HRQoL in a Korean GERD population. Methods This was a prospective, multicenter study involving a total of 824 GERD patients. The response to treatment was assessed at week 4 (or week 8 for the patients who did not achieve complete resolution [CR] at week 4). The EQ-5D questionnaire was used at baseline, end of treatment, and first recurrence to assess the HRQoL. To assess GERD symptoms, contact of patients by phone at 1, 6, and 12 months following treatment was carried out. Results CR was achieved in 65.6% and recurrence was observed in 47.8% following treatment. CR and recurrence rates did not differ by the presence of esophagitis. Multivariate analysis revealed that acid regurgitation (odds ratio 2.249; 95% confidence interval 1.293–3.912; P = 0.004) and both acid regurgitation and heartburn (odds ratio 2.330; 95% confidence interval 1.392–3.901; P = 0.001) were independent risk factors for GERD recurrence. EQ-5D scores were more improved in patients with CR than in those without CR, and worsened more during follow-up in patients with recurrence than in those without recurrence. Conclusions We should achieve complete symptom relief and attempt to prevent recurrence in GERD patients to improve their HRQoL.

Abstract
BACKGROUND The 5-HT(3) receptor antagonists are known to be effective for the treatment of diarrhea-predominant irritable bowel syndrome (IBS), but not widely used yet. The aim of this study was to compare the efficacy and safety of ramosetron, a 5-HT(3) receptor antagonist, and mebeverine in male patients with IBS with diarrhea (IBS-D). METHODS This study was performed in a multicenter, randomized, open-label design. Data of 343 male patients with IBS-D who were randomized to either a 4-week treatment of ramosetron 5μg once daily or a 4-week treatment of mebeverine 135 mg three times daily were analyzed by the intent-to-treat analysis. The primary efficacy parameter was the proportion of patients with adequate relief of IBS symptoms at the last week of treatment. The secondary endpoints were changes in each symptom score and the safety profiles. KEY RESULTS The responder rates for global IBS symptoms, abdominal pain/discomfort and abnormal bowel habits in the ramosetron and mebeverine groups significantly increased during the treatment period. The severity scores of abdominal pain/discomfort and urgency, the stool form score, and the stool frequency in both treatment arms were significantly reduced, compared with the baselines. There were no significant differences in the responder rates (37%vs 38% on ITT analysis) and adverse event profiles between the ramosetron and mebeverine groups. Neither severe constipation nor ischemic colitis was reported by ramosetron-treated patients. CONCLUSIONS & INFERENCES Ramosetron 5μg once daily is as effective as mebeverine three times daily in male patients with IBS-D.

Abstract
BACKGROUND It is unknown whether microalbuminuria is associated with non-alcoholic fatty liver disease (NAFLD) among patients with prediabetes and type 2 diabetes mellitus (DM). This study investigated the association of NAFLD with microalbuminuria among patients with prediabetes and diabetes. METHODS We evaluated 1361 subjects who had an abnormal oral glucose tolerance test (OGTT) on routine screening. All participants were divided into two groups, prediabetes and newly diagnosed type 2 DM, and the association of NAFLD with metabolic parameters on microalbuminuria was analysed. RESULTS The patients with NAFLD had higher prevalence rates of microalbuminuria (6.3% vs 19%; P = 0.001 in prediabetes, 4.5% vs 32.6%; P < 0.001 in diabetes) and also had a greater albumin-to-creatinine ratio (14.6 +/- 52.0 microg/mg Cr vs 27.7 +/- 63.9 microg/mg Cr; P = 0.051 in prediabetes, 11.4 +/- 21.4 microg/mg Cr vs 44.7 +/- 76.4 microg/mg Cr; P < 0.001 in diabetes) than those without NAFLD. The logistic regression analysis showed that NAFLD was associated with increased rates of microalbuminuria (odds ratio 3.66; 95%confidence interval (CI) 1.31-10.20, P = 0.013 in prediabetes, odds ratio 5.47;95% CI 1.01-29.61, P = 0.048 in diabetes), independently of age, sex, body mass index, waist circumference, liver enzymes, lipid profiles, HbA1c, insulin resistance as estimated by homeostasis model assessment, hypertension,smoking status and the metabolic syndrome. CONCLUSIONS The results of our study revealed a strong relationship between microalbuminuria and NAFLD in the patients with prediabetes and newly diagnosed diabetes. Further studies are required to confirm whether NAFLD is a predictor of the development of microalbuminuria in patients with prediabetes and diabetes.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is associated with a high prevalence of diabetes mellitus (DM). Insulin resistance (IR) is known to play a crucial role in the development of DM in chronic hepatitis C (CHC) patients. We prospectively investigated changes of insulin sensitivity in CHC patients during a 5-year period and analysed the factors significantly associated with IR. METHODS Sixty-two CHC patients with normal insulin sensitivity (CHC group), and a healthy control group of 172 subjects matched by age, gender, body mass index and lifestyles were studied. We compared the initial baseline insulin sensitivity, metabolic parameters and incidence of IR at the end of the follow-up period between the two groups. The changes in insulin sensitivity, metabolic parameters and the development of IR were analysed as well as factors associated with the development of IR. RESULTS IR developed in 22.5% of 62 CHC patients and 5.2% of 172 normal individuals (P < 0.001). HCV infection per se and the genotype 1 were independent risk factors for the development of IR. The duration of infection > or = 120 months, initial fasting glucose 90-100 mg/dL, fasting insulin > or = 10 microIU/mL and the homeostasis model assessment (HOMA-IR) 2.3-2.7 were significantly associated with the development of IR in the CHC group. CONCLUSION HCV infection was an independent risk factor for the development of IR. All CHC patients, even those with normal insulin sensitivity, require careful monitoring for the development of IR.

Abstract
AIM: To determine the clinical data that might be useful for differentiating benign from malignant gallbladder (GB) polyps by comparing radiological methods, including abdominal ultrasonography (US) and computed tomography (CT) scanning, with postoperative pathology findings.
METHODS: Fifty-nine patients underwent laparoscopic cholecystectomy for a GB polyp of around 10 mm. They were divided into two groups, one with cholesterol polyps and the other with non-cholesterol polyps. Clinical features such as gender, age, symptoms, size and number of polyps, the presence of a GB stone, the radiologically measured maximum diameter of the polyp by US and CT scanning, and the measurements of diameter from postoperative pathology were recorded for comparative analysis.
RESULTS: Fifteen of the 41 cases with cholesterol polyps (36.6%) were detected with US but not CT scanning, whereas all 18 non-cholesterol polyps were observed using both methods. In the cholesterol polyp group, the maximum measured diameter of the polyp was smaller by CT scan than by US. Consequently, the discrepancy between those two scanning measurements was greater than for the non-cholesterol polyp group.
CONCLUSION: The clinical signs indicative of a cholesterol polyp include: (1) a polyp observed by US but not observable by CT scanning, (2) a smaller diameter on the CT scan compared to US, and (3) a discrepancy in its maximum diameter between US and CT measurements. In addition, US and the CT scan had low accuracy in predicting the polyp diameter compared to that determined by postoperative pathology.

Adenosine receptor agonists modulate visceral hyperalgesia in the rat. Gut Liver 2008; 2:39-46. [PMID: 20485609 DOI: 10.5009/gnl.2008.2.1.39] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2008] [Accepted: 04/02/2008] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND/AIMS Adenosine is an endogenous modulator of nociception. Its role in visceral nociception, particularly in visceral hyperalgesia, has not been studied. The aim of this study was to determine the effects of adenosine receptor agonists in a model of visceral hyperalgesia. METHODS The visceromotor response (VMR) in rats to colorectal distension (CRD; 80 mmHg, 20 seconds) was quantified by electromyographic recordings from the abdominal musculature. Three hours after the intracolonic administration of zymosan (25 mg/mL, 1 mL), VMRs to CRD were measured before and after either subcutaneous or intrathecal administration of an adenosine receptor agonist. RESULTS Subcutaneous injection of 5'-N-ethylcarboxyamidoadenosine (NECA; an A1 and A2 receptor agonist), R(-)-N6-(2-phenylisopropyl)-adenosine (R-PIA; a selective A1 receptor agonist), or CGS-21680 hydrochloride (a selective A2a receptor agonist) dose-dependently (10-100 mg/kg) attenuated the VMR to CRD, although hindlimb weakness occurred at the higher doses tested. Intrathecal administration of NECA or R-PIA dose-dependently (0.1-1.0 microg/kg) decreased the VMR, whereas CGS-21680 hydrochloride was ineffective over the same concentration range. Higher intrathecal doses of the A1/A2 receptor agonist NECA produced motor weakness. CONCLUSIONS Adenosine receptor agonists are antihyperalgesic, but also produce motor weakness at high doses. However, activation of the spinal A1 receptor significantly attenuates the VMR to CRD without producing motor weakness.

Abstract
BACKGROUND AND STUDY AIMS The conventional procedure of ingestion of an entire dose of polyethylene glycol solution on the day before early-morning colonoscopy may result in poor bowel preparation. The aim of this study was to evaluate the efficacy and effect of a split-dose ingestion of polyethylene glycol for early-morning colonoscopy. METHODS A total of 303 age- and sex-matched consecutive individuals presenting for medical check-ups were randomly assigned to receive either 4 L of polyethylene glycol solution with a soft diet on the day before colonoscopy (n = 152; group A), or 3 L of polyethylene glycol solution with a soft diet on the preceding day and then 1 L of the solution on the day of colonoscopy (n = 151; group B). The quality of bowel preparation was evaluated using the Ottawa scale, and the time to cecal intubation and the technical difficulty during the procedure were also recorded. RESULTS There was no difference in compliance between group A (single-dose) and group B (split-dose). The quality of bowel preparation was better in group B compared with group A. When the participants were categorized according to compliance (good compliance, 116 in group A, 119 in group B; poor compliance, 36 in group A, 32 in group B), the quality of the bowel preparation had a higher score in the good compliance compared with the poor compliance group, and in group B this difference was usually significant. CONCLUSIONS Split-dose bowel preparation with polyethylene glycol solution provided a better quality preparation than the conventional method for patients undergoing early-morning colonoscopy.

Abstract
BACKGROUND In cholangiocarcinoma (CC), HER-2/neu protein overexpression has rarely been reported and the results are conflicting. The present study aimed to clarify the rates of HER-2/neu protein overexpression and gene amplification in human extrahepatic CC and to evaluate the correlation between HER-2/neu and several clinicopathologic features. PATIENTS AND METHODS We investigated HER-2 gene amplification by chromogenic in situ hybridization (CISH) and HER-2/neu protein overexpression by immunohistochemistry in 55 extrahepatic CC patients who underwent curative surgery at our institution. RESULTS Overexpression of HER-2/neu protein (staining intensity score > or = 2) was found in 16 out of 55 patients (29.1%). CISH revealed that HER-2 gene signals were increased in 10 out of 55 patients (18.1%). There was a positive and significant correlation between HER-2 gene amplification and HER-2/neu protein overexpression (Spearman's rho = 0.718, P < 0.01). In subgroup with lymph node metastases, HER-2 gene amplification by CISH was significant prognostic factor for survival (OR 43.6, 95% confidence interval 1.6-1219.6). CONCLUSIONS HER-2/neu protein overexpression by HER-2 gene amplification may occur in human extrahepatic CC and constitute an independent prognostic factor in patients with lymph node metastases. In subgroup with lymph node metastases who exhibit HER-2/neu overexpression might constitute potential candidates for new adjuvant therapy, such as humanized monoclonal antibodies.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has been associated with metabolic disorders, including central obesity, dyslipidema, hypertension, and hyperglycemia. Metabolic syndrome, obesity, and insulin resistance are major risk factors in the pathogenesis of NAFLD. The aim of this study was to identify the relative contribution of the metabolic syndrome, obesity, and insulin resistance to alanine aminotransferase (ALT) activity in NAFLD. A total of 3091 subjects diagnosed with fatty liver by ultrasonography were enrolled. All components of metabolic syndrome criteria, anthropometric parameters, fasting insulin levels, high-sensitivity C-reactive protein (hs-CRP) as an inflammation marker, and ALT were measured in each subject. Homeostasis model assessment--insulin resistance (HOMA-IR) as a measure of insulin resistance and body mass index (BMI) as a measure of obesity were calculated. The prevalence of increased ALT levels (>40 IU/L) was 26.7%. Increased ALT activity was significantly associated with the following characteristics: male sex, young age, increased triglycerides, fasting glucose, fasting insulin, HOMA-IR, hs-CRP, waist circumference, BMI and diastolic blood pressure, and decreased high-density lipoprotein cholesterol (HDL-C). According to the increase in the number of metabolic syndrome components, BMI, HOMA-IR, and hs-CRP, the prevalence and odds ratio for having increased ALT activity were significantly increased. Central obesity, raised triglycerides, reduced HDL-C, and raised fasting glucose were strongly associated with increased ALT activity. In conclusion, a number of metabolic syndrome components, obesity, insulin resistance, and hs-CRP, are strong predictors of increased ALT activity in NAFLD. Central obesity, raised triglycerides, reduced HDL-C, and raised fasting glucose are metabolic syndrome components that contributed to increased ALT activity.

Abstract
BACKGROUND We presumed that identification of the factors associated with improvement of fatty livers disease (FLD) would support the therapeutic options for FLD. The goal of this study was to clarify what clinical characteristics are associated with biochemical and sonographic improvements in the non-alcoholic population with fatty livers. METHODS A total of 615 non-alcoholic men had elevated alanine aminotransferase (ALT) (> or = 40 IU/L) levels and sonographic evidence of a fatty liver, and their clinical characteristics were assessed at the beginning of the study and after 1 year of follow up. The improvement was defined as combination of normal ALT level and negative sonography for hepatic fat after 1 year. Programmed intervention or medications were not applied in this study population. RESULTS The overall rate of improvement of FLD after a 1-year follow up was 37/615 (6.0%). The improvement was strongly associated with decrement of changes in bodyweight, body mass index, waist circumference, gamma-glutamyltransferase, fasting blood sugar, total cholesterol, triglycerides, low-density lipoprotein cholesterol, total cholesterol/high-density lipoprotein cholesterol ratio and homeostasis model assessment. Multivariate analysis showed that decrement of changes in bodyweight (odds ratio (OR) = 1.56; 95% confidence interval (95%CI): 1.27-1.92) per 1 kg, body mass index (OR = 2.42; 95%CI: 1.58-3.71) per 1 SD (0.8 kg/m2), waist circumference (OR = 2.13; 95%CI: 1.02-4.54) per 1 cm, and low-density lipoprotein cholesterol (OR = 1.64; 95%CI: 1.05-2.56) per 1 SD (22 mg/dL) were all independent predictors for improvement of FLD. CONCLUSIONS These results suggest that the reduction of bodyweight is a major key point for the improvement of FLD.

Abstract
A 40-year-old woman was admitted because of abdominal pain and diarrhea. She sometimes experienced paroxysmal hypertension, sweating, headache, and palpitation. Sigmoidoscopic findings showed well-demarcated diffuse mucosal edema, hyperemia, and easy touch bleeding from distal descending colon up to the splenic flexure area. Barium x-ray showed loss of haustral marking, thumb printing appearance, and diffuse luminal stenosis in the transverse, descending, and sigmoid colon. On the abdominal computed tomogram, a 3.8-cm sized well-enhanced right adrenal mass was incidentally found. Twenty-four hour urinary excretion of vanillyl mandelic acid, norepinephrine, and normetanephrine were increased. Iodine131 metaiodobenzylguanidine scan showed hot uptake on the right adrenal gland compatible with pheochromocytoma. Exploratory laparotomy was done under the impression of ischemic colitis associated with pheochromocytoma. Adrenalectomy and resection of the stenotic left colon were performed. After surgery, pain subsided, blood pressure fell gradually, blood sugar and catecholamine level became normal, and bowel habit returned to normal.
