RESUMO
BACKGROUND: Adenoma detection rate (ADR) is an important indicator of colonoscopy quality and colorectal cancer incidence. Both linked-color imaging (LCI) with artificial intelligence (LCA) and LCI alone increase adenoma detection during colonoscopy, although it remains unclear whether one modality is superior. This study compared ADR between LCA and LCI alone, including according to endoscopists' experience (experts and trainees) and polyp size. METHODS: Patients undergoing colonoscopy for positive fecal immunochemical tests, follow-up of colon polyps, and abdominal symptoms at a single institution were randomly assigned to the LCA or LCI group. ADR, adenoma per colonoscopy (APC), cecal intubation time, withdrawal time, number of adenomas per location, and adenoma size were compared. RESULTS: The LCA (n=400) and LCI (n=400) groups showed comparable cecal intubation and withdrawal times. The LCA group showed a significantly higher ADR (58.8% vs. 43.5%; P<0.001) and mean (95%CI) APC (1.31 [1.15 to 1.47] vs. 0.94 [0.80 to 1.07]; P<0.001), particularly in the ascending colon (0.30 [0.24 to 0.36] vs. 0.20 [0.15 to 0.25]; P=0.02). Total number of nonpolypoid-type adenomas was also significantly higher in the LCA group (0.15 [0.09 to 0.20] vs. 0.08 [0.05 to 0.10]; P=0.02). Small polyps (≤5, 6-9mm) were detected significantly more frequently in the LCA group (0.75 [0.64 to 0.86] vs. 0.48 [0.40 to 0.57], P<0.001 and 0.34 [0.26 to 0.41] vs. 0.24 [0.18 to 0.29], P=0.04, respectively). In both groups, ADR was not significantly different between experts and trainees. CONCLUSIONS: LCA was significantly superior to LCI alone in terms of ADR.

Several new treatments for ulcerative colitis have been developed recently. The depletion of leukocytes by granulocyte and monocyte adsorption apheresis (GMA) was developed and adapted for patients with ulcerative colitis with rare adverse events. We investigated whether treatment with GMA and prednisolone (GMAâ +â PSL) is more effective than PSL alone for patients with moderate to severe ulcerative colitis. Forty-seven patients with moderate to severe ulcerative colitis were retrospectively analyzed. Among the 47 patients, 27 received PSL, while 20 received GMAâ +â PSL. The clinical activity of ulcerative colitis was evaluated using the Lichtiger clinical activity index (CAI) and serum levels of C-reactive protein. Mayo endoscopic score (MES) was used to examine endoscopic activity. The clinical remission rate was significantly higher in the GMAâ +â PSL group than in the PSL group (65% vs 29.6%, pâ =â 0.0206). The mucosal healing rate was also significantly higher in the GMAâ +â PSL group than in the PSL group (60% vs 26%, pâ =â 0.0343). The combination of GMA and steroids may be more effective than steroids alone for inducing clinical remission and mucosal healing in patients with moderate to severe ulcerative colitis.
RESUMO
Zinc intake has reduced hospitalizations in patients with ulcerative colitis (UC), highlighting the need to maintain blood zinc levels. This prospective study investigated whether the promotion of zinc intake and a Japanese diet (high in n-3 fatty acids) could induce clinical remission in patients with mild active UC. Patients with mild active UC were randomly assigned to either (1) continue an unrestricted diet or (2) receive nutritional guidance promoting zinc intake and a Japanese diet. The primary endpoint was clinical remission at 24 weeks. Secondary endpoints were the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) scores, Clinical Activity Index (CAI), Geboes Histopathology Score (GHS), and biomarkers, including zinc levels, measured at 12 and 24 weeks. Nutritional assessments were performed using the Food Frequency Questionnaire. The CAI, UCEIS, and GHS scores were significantly lower in the intervention group than in the control group, with a significantly higher proportion of patients achieving clinical remission. Furthermore, the intervention group exhibited weight gain and significantly increased blood zinc levels. The combination of promoting dietary zinc intake and a Japanese diet rich in n-3 fatty acids can induce clinical remission in patients with mild active UC.
RESUMO
BACKGROUND AND AIM: This study aimed to compare the mean number of adenomas in patients undergoing Endo-wing-assisted colonoscopy (EAC) and transparent hood-assisted colonoscopy (TAC). METHODS: Patients undergoing colonoscopy for positive fecal immunochemical tests, colon polyp surveillance, and evaluation of abdominal symptoms at a single institution were randomly assigned to the EAC or TAC group. The mean number of adenomas per patient, adenoma detection rate, cecal intubation time, withdrawal time, mean number of adenomas per location, and adenoma size were compared. RESULTS: Overall, 800 patients were enrolled. The EAC and TAC groups comprised 372 and 393 patients, respectively. The groups did not significantly differ with respect to cecal intubation and withdrawal times. The mean number of adenomas per patient was significantly higher in the EAC group (1.13 vs 0.90, P = 0.04), particularly in the sigmoid colon (0.54 [201/372] vs 0.38 [149/393], P = 0.04). The adenoma detection rates were 48.1% and 45.0% in the EAC and TAC groups, respectively, albeit without significant difference between the two groups (P = 0.393). The total number of sessile-type adenomas (0.73 [270/372] vs 0.47 [183/393], P < 0.0001) and small polyps (≤ 5 mm) (0.53 [198/372] vs 0.41 [159/393], P = 0.016) was significantly higher in the EAC group. CONCLUSION: Endo-wing-assisted colonoscopy is significantly superior to TAC in terms of the mean number of adenomas per patient.

BACKGROUND AND AIMS: Laser endoscopy involves blue laser imaging in bright mode (BLI-bright). Linked color imaging (LCI) is superior to white light imaging (WLI) for detecting gastric cancers. This study aimed to detect gastric cancers on screening endoscopy using not only WLI but also BLI-bright and LCI in patients with atrophic gastritis. PATIENTS AND METHODS: A total of 500 patients with atrophic gastritis undergoing screening esophagogastroduodenoscopy were included. The gastric lumen was observed in the WLI mode, followed by the LCI and BLI-bright modes. When gastric neoplasms were suspected, the mode was changed to WLI, and we sprayed indigo carmine. Finally, biopsy specimens were taken for those lesions and pathological diagnosis was made. We compared the size, morphology, and color of gastric neoplasms found by the first WLI mode and those detected by only the LCI mode or BLI-bright mode. RESULTS: We detected 16 gastric neoplasms (3.2%), of which 13 were early gastric cancers (EGCs) and three were gastric adenomas. Ten EGCs and two gastric adenomas (75%) were detected by the first WLI mode; three EGCs and one gastric adenoma (25%) were missed by the first WLI mode and were detected by the LCI mode or BLI-bright mode. All were less than 1 cm in diameter and were reddish. Mean diameter of the lesions was significantly less for LCI-detected or BLI-bright-detected lesions than for WLI-detected lesions (7.8 vs 21.2 mm). CONCLUSIONS: Laser endoscopy is useful for detecting EGCs by LCI for patients with atrophic gastritis.

BACKGROUND AND AIM: The adenoma detection rate is an important indicator of colonoscopy quality and colorectal cancer incidence. We compared the adenoma detection rates between white light imaging (WLI) and linked color imaging (LCI) colonoscopy. METHODS: Patients undergoing colonoscopy for positive fecal immunochemical tests, follow-up of colon polyps, and abdominal symptoms at three institutions were randomly assigned to the LCI or WLI groups. Mean adenoma number per patient (including based on endoscopists' experience), adenoma detection rate, cecal intubation time, withdrawal time, mean adenoma number per location, and adenoma size were compared. RESULTS: The LCI and WLI groups comprised 494 and 501 patients, respectively. No significant differences in the cecal intubation rate (LCI vs WLI: 99.5% vs 99.4%), cecal intubation time, and withdrawal time were noted between groups. The mean adenoma number per patient was significantly higher in the LCI group than in the WLI group (1.07 vs 0.88, P = 0.04), particularly in the descending [0.12 (58/494) vs 0.07 (35/501), P = 0.01] and sigmoid colon [0.41 (201/494) vs 0.30 (149/501), P ≤ 0.001]. However, the adenoma detection rate was 47.1% in the LCI group and 46.9% in the WLI group, with no significant difference (P = 0.93). The total number of sessile-type adenomas was significantly higher in the LCI group than in the WLI group (346/494 vs 278/501, P = 0.04). As for polyp size, small polyps (≤ 5 mm) were detected at a significantly higher rate in the LCI group (271/494 vs 336/501, P = 0.04). CONCLUSION: Linked color imaging is significantly superior to WLI in terms of mean adenoma number per patient.

BACKGROUND AND AIM: Transparent hood-assisted colonoscopy (TAC) has been reported to improve the cecal insertion rate and adenoma detection rate (ADR). An endoscopic cap (Endocuff) with two rows of soft wings was recently developed to improve ADR, by flattening the mucosal folds during withdrawal. This randomized prospective control study aimed to compare ADR between Endocuff-assisted colonoscopy (EAC) and TAC. METHODS: A total of 513 patients undergoing colon adenoma screening were included. EAC was performed in 256 patients and TAC in 260 patients. Cecal intubation rate, cecal intubation time, ADR, and mean adenoma number per patient (MAP) were investigated in both groups (clinical trial registration: UMIN000016278). RESULTS: We excluded six patients in the EAC group and two patients in the TAC group because of colonic stenosis due to colonic adenocarcinomas. Finally, 250 patients (151 men/99 women, median age 62.1 years) were assigned to EAC and 258 patients (165 men/93 women, median age 64.3 years) were assigned to TAC. There were no significant differences in cecal intubation rate, intubation time, withdrawal time, and cleanliness score between groups. The ADR was 50.8% in EAC and 52.7% in TAC, with no significant difference (P = 0.666). The MAP was 1.35 in EAC and 1.20 in TAC, with no significant difference (P = 0.126). However, The MAP of diminutive adenomas (< 5 mm) tended to be higher in EAC than in TAC (P = 0.077). There was no significant difference in MAP in each segment between groups. CONCLUSIONS: Endocuff-assisted colonoscopy might be equivalent to TAC in cecal intubation time, ADR, and MAP.

BACKGROUND: Eosinophilic esophagitis (EoE) is related to allergic diseases such as bronchial asthma (BA), atopic dermatitis, and allergic rhinitis. The aim of this study was to examine the eosinophil infiltration in the upper gastrointestinal (GI) tract in patients with BA using esophagogastroduodenoscopy. METHODS: Patients with BA who had upper GI tract symptoms were enrolled. Patients who received systemically administered steroids were excluded. Eosinophil infiltrations in the esophagus, stomach, and duodenum were examined with regard to the endoscopic findings and pathological findings of biopsy specimens (UMIN000010132). RESULTS: Ninety patients were enrolled from October in 2012 to September in 2014. Thirty-six were male, 54 were female, and the mean age was 57.5 years. Eighty-one (90%) used inhaled corticosteroids. Fourteen patients (15.6%) had reflux esophagitis, 8 of whom had grade A and 6 had grade B. No patient with EoE was observed. One female patient who had marked eosinophil infiltration in the esophagus, stomach, and duodenum was diagnosed as having eosinophilic gastroenteritis, but endoscopy showed only mucosal edema in the antrum. Another female patient who had marked eosinophil infiltration in the esophagus, stomach, and duodenum was diagnosed as having eosinophilic granulomatosis with polyangiitis, and endoscopy showed erosions in the antrum and the duodenum. Three patients had eosinophil infiltration in the stomach, but none of them had severe symptoms. CONCLUSIONS: Patients with asthma who had upper gastrointestinal symptoms rarely had eosinophilic gastrointestinal disorders. Biopsy specimens are of high importance in the diagnosis of eosinophilic gastrointestinal disorders even if there is no remarkable endoscopic finding.

Revised idiopathic pulmonary fibrosis treatment guidelines were published in 2015, and nintedanib was conditionally recommended. Although diarrhea is reported to be a common major adverse event associated with nintedanib, there have been few reports on detailed endoscopic findings of nintedanib-associated enterocolitis. A 74-year-old woman was diagnosed with idiopathic pulmonary fibrosis 4 years ago in May. She was started on nintedanib (300 mg). Three months later, hepatic dysfunction was observed; therefore, the drug was temporarily discontinued and then resumed at a dose reduction of 200 mg. Five months later, the patient developed diarrhea, and the dose was reduced to 150 mg. However, no effect was noted; hence, colonoscopy was performed. Various inflammatory lesions, such as erythema and erosions, were observed continuously at the rectum, which resembled ulcerative colitis. No improvement was observed 2 months after follow-up colonoscopy, and nintedanib-related enterocolitis was suspected. The dose was further reduced to 100 mg. Since the endoscopic findings of nintedanib-associated enterocolitis are similar to those of ulcerative colitis, it is critical to consider patients with diarrhea who are taking nintedanib as having associated enterocolitis and attempt to reduce or discontinue the drug if diarrhea does not improve with antidiarrheal agents.

Background and Aim: The use of a hood at the tip of a colonoscope enables aspiration, inversion of the diverticulum, and observation of the inside of the diverticulum. In most previous studies, a short hood was used; however, observation of the diverticulum is often inadequate. Long food is promising by previous research, but it was a retrospective study using propensity matching and has some limitations. We compared the identification rate of stigmata of recent hemorrhage (SRH) between the long and standard hoods in cases of suspected colonic diverticular hemorrhage (CDH) to confirm the usefulness of long hood by prospective randomized controlled trial. Methods: Eighty patients (42 in the long hood group [L group] and 38 in the short hood group [S group]) who visited the Saitama Medical University Hospital and Tokai University Hachioji Hospital between December 2018 and July 2021 with a chief complaint of bloody stool and suspected CDH, based on the clinical course and imaging studies, were included. Patients were randomly assigned to the L or S group. Results: Regarding patient background, age was significantly higher in the L group; however, no significant differences were found in medical history or history of antithrombotic medication or nonsteroidal anti-inflammatory drug use. Identification rate of SRH was significantly higher in the L group (58.5%, 24/42 patients) than in the S group (26.3%, 10/38 patients) (P < 0.05). All patients were treated using the clip method, and the rate of rebleeding within 1 month was not significantly different between the two groups. Conclusion: A long hood was more useful compared with a short hood in identifying SRH of CDH (UMIN000034603).
RESUMO
The pathologic diagnosis of duodenal tumors is a developing field; however, its overview remains unclear. We describe a rare case of a duodenal gastric-type neoplasm in a 50-year-old woman. She visited her primary care doctor with complaints of upper abdominal pain, tarry stools, and shortness of breath on exertion. She was admitted owing to a stalked polyp with erosion and hemorrhage in the descending part of the duodenum. Endoscopic mucosal resection (EMR) was performed on the polyp. Histologically, the resected polyp was a lipomatous lesion in the submucosal layer, composed of mature adipose tissues. Scattered irregular lobules of Brunner's gland-like structures with well-preserved construction but mildly enlarged nuclei and occasional conspicuous nucleoli of the constituent cells were observed. The resection margin was negative. EMR findings of the duodenal polyp showed a gastric epithelial tumor within a lipoma, a rare histological type that has not been reported previously. This tumor may be classified as a "neoplasm with uncertain malignant potential" in a lipoma, an intermediate category between adenoma and invasive adenocarcinoma. There is no consensus on treatment, and careful follow-up is recommended. This is the first report of a duodenal gastric-type neoplasm with uncertain malignant potential in a lipoma.

Rituximab (RTX) is effective for treating cancer, but reports of RTX-associated enterocolitis are limited. We herein report the case of a 65-year-old man who developed RTX-induced ileocolitis. He was diagnosed with gastric mucosa-associated lymphoid tissue lymphoma (MALToma) and treated with RTX. He complained of bloody diarrhea after RTX. Mucosal inflammation on colonoscopy indicated RTX-induced ileocolitis. He was treated with corticosteroids, and his symptoms improved. We reviewed the RTX-associated gastrointestinal adverse events and classified the features into ulcerative colitis, Crohn's disease, microscopic colitis, and ileocolitis. To our knowledge, this is the first case of a Japanese patient who developed RTX-induced ileocolitis.

A 49-year-old man complained of chronic palpitation and shortness of breath, which had recently become exacerbated. A blood examination indicated severe refractory anemia and hypoproteinemia. Physical examinations revealed anemia, a systolic murmur, and spoon nails. Multiple nonspecific ileal ulcers were observed. A pathological examination indicated a small granuloma with CD68-positive histiocytes. He had a deeply wrinkled forehead, chiseled face, and clubbed fingers. Radiography revealed periostosis of the fingers and long bones in the limb. He was diagnosed with pachydermoperiostosis. SLCO2A1 demonstrated a c.1807C>T homo-mutation. He was also diagnosed with SLCO2A1-associated chronic enteropathy and thus was treated with 5-aminosalicylic acid, which temporarily improved the ileal ulcers, anemia, and hypoalbuminemia.

METHODS: This study was a prospective, open-label, nonblinded, multicenter, and observational study. From September 2013 to March 2017, patients taking DOACs were enrolled. Patients underwent VCE. The type and location of small-bowel lesions were registered. Also, (1) the proportion of lesions detected between types of DOAC was evaluated and (2) the hemoglobin (Hb) and serum ferritin levels were compared between patients with and without small-bowel lesions. RESULTS: 33 patients were enrolled, but 4 patients withdrew their consent, and VCE was performed on 29 patients. Eight, 13, and 8 patients received dabigatran, rivaroxaban, and apixaban, respectively. Small-bowel transit was complete in 27 of 29 patients (93.1%). Small-bowel lesions were detected in 23 (79.3%), redness in 12 (41.4%), erosions in 14 (48.3%), and angioectasia in 3 (10.3%) patients, and 6 patients (20.7%) had no abnormalities. Redness and erosions were detected in the upper, middle, or lower portions, but erosions tended to be less frequent in the middle portion (p = 0.25, 0.06). Angioectasia was not detected in the lower portion. No patients had active bleeding. The findings did not differ according to the drug. The relationships between the endoscopic findings and the Hb and serum ferritin levels were not significant. CONCLUSION: Many patients taking DOACs had small-bowel lesions; however, most lesions were relatively mild. Observing small-bowel lesions over longer periods may be necessary in patients taking DOACs. This trial is registered with UMIN000011527.
RESUMO
No specific endoscopic features for eosinophilic gastroenteritis (EGE) have been reported previously. This study therefore evaluated the endoscopic findings of six patients with EGE. The diagnosis was confirmed based on gastrointestinal symptoms, pathological findings on biopsy, and the absence of other diseases. The site of the lesion was identified based on eosinophilic infiltration with ≥20 cells per high-power field during a pathological specimen analysis. Flattening of the small intestinal villi was observed in four patients; we speculate that this may be a specific feature in the diagnosis of EGE.

A 19-year-old female was diagnosed with ulcerative colitis when she presented with persistent melena, and has been treated with 5-aminosalicylic acid for 4 years, with additional azathioprine for 2 years at our hospital. The patient experienced high-grade fevers, chills, and cough five d prior to presenting to the outpatient unit. At first, the patient was suspected to have developed neutropenic fever; however, she was diagnosed with Epstein-Barr virus-associated hemophagocytic syndrome (EB-VAHS) upon fulfilling the diagnostic criteria after bone marrow aspiration. When patients with inflammatory bowel disease treated with immunomodulators, such as thiopurine preparations, develop fever, EB-VAHS should be considered in the differential diagnosis.
RESUMO
We examined whether serum gammaGTP activity (gammaGTP) is associated with Breslow's lifestyle index and whether it could be used as a tool to detect subjects with unhealthy lifestyles. To that effect, 724 male Japanese workers excluding patients suffering from hepatitis virus infection, autoimmune liver diseases and apparently active bile duct diseases were cross-sectionally examined. gammaGTP was inversely associated with the total score of Breslow's index for all subjects (lambda=30.643) and in subjects aged 40 or more (lambda=37.073). The association was consistent even after adjustments of subjects' ages and levels of triglycerides, total cholesterol and uric acid (p=0.0001). Among the seven lifestyle factors comprising Breslow's index, improper habits of drinking (p<0.0001), smoking (p=0.0204), exercise (p=0.0189) and body weight control (p<0.0001), were associated with increased gammaGTP. Even in a survey in which subjects who had proper habits of drinking and body weight control were selectively examined, improper habits of smoking and exercise still tended to be associated with increased gammaGTP. Receiver operating characteristic curves indicated that gammaGTP was beneficial for detecting subjects who scored two or less on Breslow's index, at least in subjects aged 40 or more. gammaGTP was associated with insulin resistance level estimated by the homeostasis model assessment (p<0.0001), which was inversely associated with Breslow's index (p=0.0040). gammaGTP could be used as an objective substitute of Breslow's index, allowing us to identify subjects with low scores on Breslow's index, at least after sorting subjects properly. Such screening would enable interventions to correct subjects' unhealthy lifestyles, helping to solve lifestyle-related disease issues.

AIM: To evaluate the morphology of the colon in patients with irritable bowel syndrome (IBS) by using computed tomography colonography (CTC). METHODS: Twelve patients with diarrhea type IBS (IBS-D), 13 patients with constipation type IBS (IBS-C), 12 patients with functional constipation (FC) and 14 control patients underwent colonoscopy following CTC. The lengths of the rectosigmoid colon, transverse colon and the total colon were measured. The diameters of the rectum, sigmoid colon, descending colon, transverse colon, and ascending colon were measured. RESULTS: The mean length of the total colon was 156.5 cm in group C, 158.9 cm in group IBS-D, 172.0 cm in group IBS-C, and 188.8 cm in group FC. The total colon in group FC was significantly longer than that in group C (P < 0.05). The mean length of the rectosigmoid colon was 56.2 cm, 55.9 cm, 63.6cm, and 77.4 cm (NS). The mean length of the transverse colon was 49.9 cm, 43.1 cm, 57.0 cm, and 55.0 cm. The transverse colon in group IBS-D was significantly shorter than that in group IBS-C (P < 0.01) and that in group FC (P = 0.02). The mean diameter of the sigmoid colon was 4.0 cm, 3.3 cm, 4.2 cm, and 4.3 cm (NS). The mean diameter of the descending colon was 3.6 cm, 3.1 cm, 3.8 cm, and 4.3 cm. The descending colon diameter in group IBS-D was significantly less than that in group IBS-C (P = 0.03) and that in group FC (P < 0.001). The descending colon diameter in group FC was significantly greater than that in group C (P = 0.04). The mean diameter of the transverse colon was 4.4 cm, 3.3 cm, 4.2 cm, and 5.0 cm (NS). CONCLUSION: CT colonography might contribute the clarification of subtypes of IBS.

OBJECTIVE: The aim of this study was to determine whether lifestyle status affects the insulin resistance index or serum adiponectin level, which may be responsible for the development of insulin resistance syndrome that sometimes indicates lifestyle-related diseases. METHODS: A cross-sectional study was performed. PATIENTS: Seven hundred thirty-eight males aged 30 to 65 years who had regular health checkups in our office were enrolled. Each subject's lifestyle status, level of serum adiponectin, and serum insulin level were assessed by a self-administered questionnaire based on Breslow's lifestyle index, enzyme-linked immunosorbent assay, and radioimmunoassay, respectively. Moreover, their insulin resistance indexes were assessed by the homeostasis model. RESULTS: One-way ANOVA demonstrated an inverse correlation between Breslow's index and the logarithmic insulin resistance index (p<0.0001), and a tendency of a correlation between Breslow's index and the logarithmic serum adiponectin level (p=0.0681). Multiple logistic regression analyses demonstrated that, among the seven lifestyle items in Breslow's index, body mass index of more than 26.1 kg/m2 and insufficient exercise style had 8.9 times and 2.1 times the risks for insulin resistance and the former also had 3.2 times the risk for hypoadiponectinemia. Partial correlation coefficients of these correlations were 0.336 (p<0.0001), 0.107 (p=0.0013), and 0.165, (p<0.0001), respectively. CONCLUSION: Unhealthy lifestyles may cause hypoadiponectinemia and insulin resistance followed by insulin resistance syndrome, i.e. lifestyle-related diseases. These findings present reasonable explanations for the relationships between lifestyles and lifestyle-related diseases. Improvement of unhealthy lifestyles, especially the control of body weight, may have beneficial effects against the development of lifestyle-related diseases.

A pyogenic granuloma (PG) is a capillary hemangioma that usually occurs on the skin or in the oral cavity; it is rarely observed in the gastrointestinal tract. We herein describe a case of a 86-year-old woman who presented with anemia. Esophagogastroduodenoscopy and colonoscopy did not reveal any significant bleeding focus, but capsule endoscopy revealed a bleeding focus in the small intestine. We performed double-balloon enteroscopy and identified a 7-mm-diameter, reddish, subpedunculated, hemispheric polyp with a smooth surface in the small intestine, approximately 100 cm from the ileocecal valve. The polyp was surgically removed, and the histological findings were consistent with a diagnosis of PG.
