This study aimed to assess an ultra-diluted (UD) complex, as a replacement for an antimicrobial growth promoter in diets, on growth performance, intestinal health, and inflammatory response of nursery piglets. The experiment lasted 37 days and involved 126 animals weaned at 21 ± 1.3 d, with an initial body weight of 5.62 ± 1.16 kg. Piglets were assigned to six dietary treatments in a randomized block design with seven replicates and three piglets per pen as experimental unit. The treatments were: positive control (PC)- basal diet + 120 mg/kg of chlorohydroxyquinoline; negative control (NC)- basal diet without additives; and NC containing 4.5; 6.0; 7.5 or 9.0 kg of UD additive/ton diet. Performance data were calculated, and daily diarrhea was observed. Blood samples were collected for hematological analysis. At the end of the experiment, one animal per pen was slaughtered for organ weighing, pH, and the collection of intestinal samples for histopathology. Feces and cecal contents were collected for microbiological and antibiogram analyses. There was no difference in the performance between the treatments. Throughout the study, UD levels were equal to those of PC for diarrhea occurrence. Higher levels of UD complex led to higher total leukocyte counts. The 4.5 treatment showed a reduction in total and thermotolerant Enterobacteriaceae populations in piglet feces and an increase in lactic acid bacteria compared to PC. All treatments resulted in fewer duodenal histopathological alterations than those in the NC group. The use of UD additives, especially at 4.5 kg/ton, is a good alternative to chlorohydroxyquinoline in piglet diets.

BACKGROUND
Common marmosets (Callithrix jacchus) are widely used as primate experimental models in biomedical research. Duodenal dilation with chronic vomiting in captive common marmosets is a recently described life-threatening syndrome that is problematic for health control. However, the pathogenesis and cause of death are not fully understood.
CASE PRESENTATION
We report two novel necropsy cases in which captive common marmosets were histopathologically diagnosed with gastric emphysema (GE) and pneumatosis intestinalis (PI). Marmoset duodenal dilation syndrome was confirmed in each case by clinical observation of chronic vomiting and by gross necropsy findings showing a dilated, gas-filled and fluid-filled descending duodenum that adhered to the ascending colon. A diagnosis of GE and PI was made on the basis of the bubble-like morphology of the gastric and intestinal mucosa, with histological examination revealing numerous vacuoles diffused throughout the lamina propria mucosae and submucosa. Immunostaining for prospero homeobox 1 and CD31 distinguished gas cysts from blood and lymph vessels. The presence of hepatic portal venous gas in case 1 and possible secondary bacteremia-related septic shock in case 2 were suggested to be acute life-threatening abdominal processes resulting from gastric emphysema and pneumatosis intestinalis.
CONCLUSIONS
In both cases, the gross and histopathological findings of gas cysts in the GI tract walls matched the features of human GE and PI. These findings contribute to clarifying the cause of death in captive marmosets that have died of gastrointestinal diseases.

Surgery For Obesity and Related... Apr 2024Bile acids can stimulate the secretion of glucagon-like peptide-1 (GLP-1) and be mostly reabsorbed in the ileum.
BACKGROUND
Bile acids can stimulate the secretion of glucagon-like peptide-1 (GLP-1) and be mostly reabsorbed in the ileum.
OBJECTIVES
We aimed to investigate whether ileum excision could reverse the glucose improvement after biliopancreatic diversion with duodenal switch (BPD/DS).
SETTING
Peking Union Medical College Hospital.
METHODS
Thirty diabetic rats were randomly divided into the BPD/DS group, BPD/DS plus ileectomy (BDI) group, and control group. The fasting blood glucose, bile acids, and glucagon-like peptide-1(GLP-1) levels in plasma samples were analyzed.
RESULTS
In postoperative week 20, the fasting blood glucose level in the BDI group was significantly higher than that in the BPD/DS group (11.5 ± 1.4 mmol/L versus 7.6 ± 1.0 mmol/L, P < .001), and the AUC value was also significantly higher than that in the BPD/DS group (2186.1 ± 237.2 mmol/L·min versus 1551.2 ± 136.9 mmol/L·min, P < .001). The plasma level of bile acids in the BDI group was lower than that in the BPD/DS group (P = .012) and was not significantly different from that in the control group (P = .629). The plasma level of GLP-1 in the BDI group was lower than that in the BPD/DS group (P = .009) and was not significantly different from that in the control group (P = .530). Moreover, the intestinal TGR5 expression in the BDI group was significantly lower than that in the BPD/DS group (P < .001).
CONCLUSIONS
The results show that excision of the ileum can partially reverse the improvement in glucose metabolism after BPD/DS.

PURPOSE
A large proportion of Common variable immunodeficiency (CVID) patients has duodenal inflammation with increased intraepithelial lymphocytes (IEL) of unknown aetiology. The histologic similarities to celiac disease, lead to confusion regarding treatment (gluten-free diet) of these patients. We aimed to elucidate the role of epigenetic DNA methylation in the aetiology of duodenal inflammation in CVID and differentiate it from true celiac disease.
METHODS
DNA was isolated from snap-frozen pieces of duodenal biopsies and analysed for differences in genome-wide epigenetic DNA methylation between CVID patients with increased IEL (CVID_IEL; n = 5) without IEL (CVID_N; n = 3), celiac disease (n = 3) and healthy controls (n = 3).
RESULTS
The DNA methylation data of 5-methylcytosine in CpG sites separated CVID and celiac diseases from healthy controls. Differential methylation in promoters of genes were identified as potential novel mediators in CVID and celiac disease. There was limited overlap of methylation associated genes between CVID_IEL and Celiac disease. High frequency of differentially methylated CpG sites was detected in over 100 genes nearby transcription start site (TSS) in both CVID_IEL and celiac disease, compared to healthy controls. Differential methylation of genes involved in regulation of TNF/cytokine production were enriched in CVID_IEL, compared to healthy controls.
CONCLUSION
This is the first study to reveal a role of epigenetic DNA methylation in the etiology of duodenal inflammation of CVID patients, distinguishing CVID_IEL from celiac disease. We identified potential biomarkers and therapeutic targets within gene promotors and in high-frequency differentially methylated CpG regions proximal to TSS in both CVID_IEL and celiac disease.

Endoscopic resection of gastrointestinal (GI) tract lesions, originating from Japan, is becoming more frequently used in European countries. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) ensure minimally invasive removal of benign, premalignant, and early neoplastic tumors of esophagus, stomach, and intestine in selected group of patients. Aim of this study was to determine the outcomes, radical resection rate (R0), and complication rate of ESD procedures performed in our department. The data from 100 ESD procedures of esophageal, gastric, duodenal, and colorectal lesions performed in out unit between 02.01.2020 and 30.06.2023 were collected and analyzed retrospectively. A total of 42 male and 58 female patients in the median age of 64 years (range, 31-89 years) underwent ESD. Mean duration of the procedure was 66 minutes (ranging 25-185 minutes). Tumors were located in the esophagus in 8 cases (8%), stomach in 25 cases (25%), duodenum in 1 case (1%), and colon in 66 cases (66%). Radical resection was achieved in 98 cases (98%); 2 patients were qualified for surgical treatment. Average size of dissection lesions was 26 × 19 mm. The biggest one was 60 × 60 mm (sigmoid adenoma), and the smallest one was 5 × 5 mm (gastrointestinal neuroectodermal tumors). Complication occurred in 10 patients (10%)-9 perforations of the wall of intestine (9%) and 1 hemorrhage, which required endoscopic intervention (1%). Implementation of ESD to clinical practice gives the opportunity for minimally invasive, radical treatment of benign, premalignant, and early neoplastic lesions of gastrointestinal tract in selected group of patients. Experienced endoscopists, following current guidelines and standardized process of qualification, are crucial to minimize the risk of severe complications.

A variety of complications and associated clinical presentations may be seen in patients with cirrhotic and non-cirrhotic portal hypertension. We present one such case of Upper GI hemorrhage from ectopic duodenal varices in a case of pre-hepatic portal hypertension due to Extrahepatic Portal Venous Obstruction (EHPVO). The case was managed successfully with endovascular Portal Vein Recanalization (PVR) and metallic stent deployment. With adequate technical success, improved symptoms, and laboratory parameters, the patient was discharged on long-term anticoagulation and interval follow-up.

The administration of nonsteroidal anti-inflammatory drugs (NSAIDs) may cause significant intestinal alteration and inflammation and lead to the occurrence of inflammatory diseases resembling duodenal ulcers. Astragaloside IV (AS-IV) is a glycoside of cycloartane-type triterpene isolated from the dried root of Astragalus membranaceus (Fisch.) Bge. (family Fabaceae), and has been used for ameliorating the NSAID-induced inflammation in the small intestine. The present study aimed to investigate the effects of AS-IV on indomethacin (IND)-induced inflammation in the small intestine of rats and its underlying mechanisms. Hematoxylin-eosin (H&E) staining, transmission and scanning electron microscopy were carried out to observe the surface morphology and ultrastructure of the small intestinal mucosa. Immunofluorescence and ELISA tests were employed to detect the expressions of NLRP3, ASC, caspase-1, and NF-κB proteins, as well as inflammatory factors IL-1β and IL-18, to uncover potential molecular mechanisms responsible for mitigating small intestinal inflammation. The results demonstrated that AS-IV significantly decreased the ulcer index, improved the surface morphology and microstructure of the small intestinal mucosa, and increased mucosal blood flow. Molecular docking revealed a strong and stable binding capacity of AS-IV to NLRP3, ASC, caspase-1, and NF-κB proteins. Further experimental validation exhibited that AS-IV markedly decreased levels of IL-1β and IL-18, and inhibited the protein expression of NLRP3, ASC, caspase-1, and NF-κB. Our data demonstrate that AS-IV ameliorates IND-induced intestinal inflammation in rats by inhibiting the activation of NLRP3 inflammasome and reducing the release of IL-1β and IL-18, thereby representing a promising therapy for IND-induced intestinal inflammation.

A high risk of complications still accompanies gastric conduit reconstruction after esophagectomy. In this narrative review, we summarize the technological progress and the problems of gastric conduit reconstruction after esophagectomy. Several types of gastric conduits exist, including the whole stomach and the narrow gastric tube. The clinical outcomes are similar between the two types of conduits. Sufficient blood supply to the conduit is mandatory for a successful esophageal reconstruction. Recently, due to the availability of equipment and its convenience, indocyanine green angiography has been rapidly spreading. When the blood perfusion of the planning anastomotic site is insufficient, several techniques, such as the Kocher maneuver, pedunculated gastric tube with duodenal transection, and additional microvascular anastomosis, exist to decrease the risk of anastomotic failure. There are two different anastomotic sites, cervical and thoracic, and mainly two reconstructive routes, retrosternal and posterior mediastinal routes. Meta-analyses showed no significant difference in outcomes between the anastomotic sites as well as the reconstructive routes. Anastomotic techniques include hand-sewn, circular, and linear stapling. Anastomoses using linear stapling is advantageous in decreasing anastomosis-related complications. Arteriosclerosis and poorly controlled diabetes are the risk factors for anastomotic leakage, while a narrow upper mediastinal space and a damaged stomach predict leakage. Although standardization among the institutional team members is essential to decrease anastomotic complications, surgeons should learn several technical options for predictable or unpredictable intraoperative situations.

Review
A peptic ulcer is a lesion (sore) on the stomach lining, or duodenum. Peptic ulcers are probably a twentieth-century condition. The ulcer disease continues to be a significant source of worldwide morbidity and mortality. The Gastrointestinal ulcers and duodenal ulcers are considered the two most extreme types of peptic ulcers. Peptic ulcers are found to be caused by an excess of violent factors including Hydrochloric acid (HCL) pepsin, refluxed bile leukotrienes (LT), reactive oxygen species (ROS) and protective factors, these include mucus-bicarbonate barrier functions, prostaglandins (PGs), mucosal blood flow, cell regeneration and migration, non-enzymatic and enzymatic and certain growth factors. The primary cause of peptic ulcer disease is pylori infection and the use of NSAIDs. This review article underscores the importance of a multidisciplinary approach in the management of ulcers to improve patient outcomes and quality of life.
