Abstract
AIMS To evaluate comparative outcomes of laparoscopic repair of perforated peptic ulcer with omental patch versus without omental patch. METHODS A systematic search of multiple electronic data sources was conducted, and all studies comparing laparoscopic repair of perforated peptic ulcer (PPU) with and without omental patch were included. Operative time, postoperative complications, re-operation and mortality were the evaluated outcome parameters for the meta-analysis. Revman 5.3 was used for data analysis. RESULTS Four observational studies reporting a total number of 438 patients who underwent laparoscopic repair of PPU with (n = 268) or without (n = 170) omental patch were included. Operative time was significantly shorter in no-omental patch group (NOP) when compared to omental patch group (P = .02). There was no significant difference in the risk of postoperative ileus (Odd ratio (OR) .76, P = .61), leakage (OR 1.17, P = .80), wound infection (OR 1.89, P = .34), intra-abdominal abscess (OR 1.17, P = .87), re-operation (OR .00, P = .94) and mortality (OR .55, P = .48). Moreover, length of hospital stay was comparable between the two groups (P = .81). CONCLUSION Laparoscopic repair of PPU with or without omental patch have comparable postoperative complications and mortality rate. However, considering the shorter operative time, no-omental patch approach is an attractive and more favourable choice. Well-designed randomized controlled trials are needed to investigate this comparison.

Martínez-Herrero S, Martínez A. Adrenomedullin: Not Just Another Gastrointestinal Peptide. Biomolecules 2022; 12:biom12020156. [PMID: 35204657 PMCID: PMC8961556 DOI: 10.3390/biom12020156] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 01/14/2022] [Accepted: 01/15/2022] [Indexed: 12/11/2022] Open
Abstract
Adrenomedullin (AM) and proadrenomedullin N-terminal 20 peptide (PAMP) are two bioactive peptides derived from the same precursor with several biological functions including vasodilation, angiogenesis, or anti-inflammation, among others. AM and PAMP are widely expressed throughout the gastrointestinal (GI) tract where they behave as GI hormones, regulating numerous physiological processes such as gastric emptying, gastric acid release, insulin secretion, bowel movements, or intestinal barrier function. Furthermore, it has been recently demonstrated that AM/PAMP have an impact on gut microbiome composition, inhibiting the growth of bacteria related with disease and increasing the number of beneficial bacteria such as Lactobacillus or Bifidobacterium. Due to their wide functions in the GI tract, AM and PAMP are involved in several digestive pathologies such as peptic ulcer, diabetes, colon cancer, or inflammatory bowel disease (IBD). AM is a key protective factor in IBD onset and development, as it regulates cytokine production in the intestinal mucosa, improves vascular and lymphatic regeneration and function and mucosal epithelial repair, and promotes a beneficial gut microbiome composition. AM and PAMP are relevant GI hormones that can be targeted to develop novel therapeutic agents for IBD, other GI disorders, or microbiome-related pathologies.

Effect of p-cymene and rosmarinic acid on gastric ulcer healing - Involvement of multiple endogenous curative mechanisms. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 86:153497. [PMID: 33745762 DOI: 10.1016/j.phymed.2021.153497] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 01/31/2021] [Accepted: 02/04/2021] [Indexed: 05/24/2023]
Abstract
BACKGROUND p-Cymene and rosmarinic acid are secondary metabolites found in several medicinal plants and spices. Previous studies have demonstrated their anti-inflammatory, antioxidant, and cytoprotective effects. PURPOSE To evaluate their gastroduodenal antiulcer activity, gastric healing and toxicity in experimental models. METHODS Preventive antiulcer effects were assessed using oral pre-treatment on HCl/ethanol-induced gastric lesions and cysteamine-induced duodenal lesions models. Gastric healing, the underlining mechanisms and toxicity after repeated doses were carried out using the acetic acid-induced gastric ulcer rat model and oral treatment for 14 days. RESULTS In the HCl/ethanol-induced gastric ulcer and cysteamine-induced duodenal injury, p-cymene and rosmarinic acid (50-200 mg/kg) decreased significantly the ulcer area, and so prevented lesions formation. In the acetic acid-induced ulcer model, both compounds (200 mg/kg) markedly reduced the ulcerative injury. These effects were related to an increase in the levels of reduced glutathione (GSH) and interleukin (IL)-10, and due to a decrease in malondialdehyde (MDA), IL-1β, tumor necrosis factor (TNF)-α, total and mitochondrial reactive oxygen species (ROS) levels. Downregulation of factor nuclear kappa B (NFκB) and enhanced expression of suppressor of cytokine signaling (SOCS)3 were also demonstrated. Furthermore, positive vascular endothelial growth factor (VEGF), metalloproteinase (MMP)-2, and cyclooxygenase (COX-2)-stained cells were increased in treated groups. Treatment also upregulated the platelet-derived growth factor (PDGF), basic fibroblast growth factor (bFGF), transforming growth factor (TGF)-β and epidermal growth factor receptor (EGFR) in gastric tissues. In isolated gastric epithelial cells this healing effect seems to be linked to a modulation of apoptosis, proliferation, survival and protein phosphorylation, such as the extracellular signal-regulated kinases (ERK)1/2 and p38 mitogen-activated protein kinase (MAPK). Oral toxicity investigation for 14 days revealed no alterations in heart, liver, spleen, and kidneys weight nor the biochemical and hematological assessed parameters. p-Cymene and rosmarinic acid also protected animals from body weight loss maintaining feed and water intake. CONCLUSIONS Data altogether suggest low toxicity, antiulcer and gastric healing activities of p-cymene and rosmarinic acid. Antioxidant and immunomodulatory properties seem to be involved in the curative effect as well as the induction of different factors linked to tissue repair.

Abstract
BACKGROUND Topiramate (TPM), an antiepileptic drug, is also effective against alcohol dependency, a crucial factor in forming gastric ulcers. There is an increased possibility of patients with compromised gastric conditions getting exposed to TPM, but its effect on gastric ulcers is unknown. This study investigates the implication of acute TPM in ethanol-produced gastric ulceration in rats. MATERIAL AND METHODS The effect of TPM studied in male 200-225 g Sprague Dawley rats against ethanol-induced gastric ulcers and for gastric secretion and acidity. The factors assessed include gastric secretion and acidity, gastric ulcer score, biochemical and histological changes, NF-kB, and p53 expression. The analysis of data performed by using the Kruskal Wallis test and Dunnett's multiple comparison tests. RESULTS TPM pretreatment showed gastroprotective effects. It significantly reduced ethanol-induced increased gastric secretion, acidity, and gastric ulcer index and prevented gastric mucus depletion. The ethanol-induced inflammation and apoptosis were also significantly decreased by reducing the increased gastric myeloperoxidase activity and the expression of NF-kB and p53. TPM pretreatment also reduced the ethanol-induced damage to the gastric histology in rats. CONCLUSION TPM exerted a gastro-protective effect against ethanol-induced gastric ulcers mediated by reducing the gastric ulcer index, preventing a decrease of the mucus levels, reduction in inflammation, damage to gastric histology, and a decrease in the enhanced expression of NF-kB and TPM. Further detailed investigations are essential to understand the chronic influence of TPM on gastric ulcers.

Gastro-Protective Effects of Albizia anthelmintica Leaf Extract on Indomethacin-Induced Gastric Ulcer in Wistar Rats: In Silico and In Vivo Studies. Antioxidants (Basel) 2021; 10:176.

Abstract
We have previously reported that the leaf extract of Albizia anthelmintica exhibited substantial antioxidant, anti-inflammatory, analgesic, and antipyretic properties in vivo. We also comprehensively characterized the active phytoconstituents and found several flavonoids and galloyl glucosides derivatives. In the current work, we explored the gastroprotective effects of the leaf extract in an indomethacin-induced ulcer model and the mechanisms involved. The rats being pretreated with the tested extract (100 and 200 mg kg-1) significantly prevented gastric lesions by 87.4% and 92.3%, respectively, and they had no structural derangements in the gastric mucosa. The extract significantly reduced the elevated levels of IKκB, NF-κB, TNF-α, IL-6, iNOS, and lipid peroxidation; increased the reduced level of glutathione peroxidase (GPx) activity; and reduced glutathione (GSH) in the indomethacin-induced ulcer model. The protective activities of the extract were similar in most aspects to those exerted by the known anti-ulcer drug famotidine. These activities might be attributed to the anti-inflammatory and antioxidant activities, and the reduction of iNOS levels. In conclusion, Albizia anthelmintica is a potential candidate for management of gastric ulcers with antioxidant properties.

Abstract
Rosmarinic acid (RA) is a secondary metabolite present in several plant species that has already demonstrated antioxidant, antiallergic, anticancer, antimicrobial, neuroprotective, and hepatoprotective effects experimentally. Due to the promising pharmacological properties found previously, this study aimed to assess the oral acute toxicity and the gastroprotective effect of RA using animal models. Acute toxicity was assessed according to OECD guide 423. Ethanol, stress, NSAIDs, and pylorus ligature-induced gastric ulcer models were used to investigate antiulcer properties. The related mechanisms of action were also evaluated from ethanol-induced gastric lesions protocol. RA (300 and 2000 mg/kg) showed no changes in behavioral, water and food intake, body and organs weight parameters with LD50 set around 2500 mg/kg. RA presented gastroprotective activity in all assessed doses (25, 50, 100, and 200 mg/kg) using different animal models. Besides, it was observed that this effect is not related to the modulation of gastric juice parameters (pH, volume, and [H+]), the participation of nitric oxide, mucus, and prostaglandins. However, increased sulfhydryl groups, GSH and IL-10 levels as well as reduced of proinflammatory cytokine (TNF-α and IL-1β) levels were found for RA-treated groups. RA presents low acute toxicity and gastroprotective activity, preventing ulcer formation via cytoprotective, antioxidant, and anti-inflammatory mechanisms. Graphical abstract.

[PMID: 31277352 PMCID: PMC6651132 DOI: 10.3390/ijerph16132369] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/02/2019] [Revised: 06/30/2019] [Accepted: 07/02/2019] [Indexed: 12/24/2022]
Abstract
Policemen and firefighters encounter numerous emergency events that frequently lead to high burnout and low job support, resulting in adverse health effects. A number of studies reported the correlation between job characteristics and the risk of peptic ulcer diseases (PUD) across various industries. However, there is very little research on evaluating the interaction effects of burnout and job support on the prevalence of PUD among firefighters and policemen. The objective of this study was to assess the interactional effects between burnout and job support on the prevalence of PUD among firefighters and policemen. This was a cross-sectional quantitative study. Registered, full-time police officers and firefighters in Taiwan were anonymously interviewed by a mail-delivered questionnaire. All female workers were excluded due to different job characteristics and a limited sample size. A total of 9328 firefighters and 42,798 policemen completed the questionnaire, with a response rate of 78.7%. Overall, prevalence rates of self-reported and self-reports of physician-diagnosed PUD were 8.3% and 6.5% for policemen and 7.1% and 5.5% for firefighters, respectively. There was a 22% reduced odds ratio of PUD as diagnosed by physicians for the group with low burnout and high job support, but an increased odds ratio of 53% for the group with high burnout and low job support, after adjusting for lifestyle and demographic variables. There must be an increase of job support and reduction of burnout through the modification of work structure and setting up of counseling services to reduce workplace stress and the prevalence of PUD among policemen and firefighters.

[PMID: 30885738 DOI: 10.1016/j.tox.2019.03.003] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2018] [Revised: 02/21/2019] [Accepted: 03/12/2019] [Indexed: 12/11/2022]
Abstract
Acetylsalicylic acid (ASA) is the most highly consumed pharmaceutical product worldwide. Importantly, gastrointestinal ulceration due to ASA is a major complication. Hence, the present work aimed to examine, for the first time, the healing properties of bee venom (BV) in acute gastric ulceration induced by ASA. Forty adult male Sprague-Dawley rats were divided into four groups that received distilled water only, ASA (500 mg/kg BW) twice daily for 3 days, ASA for 3 days followed by BV (2 mg/kg BW) for 7 days, or ASA for 3 days followed by ranitidine hydrochloride (50 mg/kg BW) for 7 days. Haematological analysis, haemostatic evaluation, and inflammatory marker estimation were performed. Rat stomachs were collected for ulcer scoring, gene expression analysis, oxidative stress assays, histopathological and immunohistochemical examinations, and tissue eosinophil scoring. The results revealed that BV markedly decreased the ulcer index, pro-inflammatory cytokine levels, malondialdehyde levels, BAX distribution, caspase-3 expression, and tissue eosinophil levels. Additionally, significant increases in antioxidant enzymes and heat shock protein 70 localization in gastric tissue were evident following BV treatment after ASA exposure. Also, BV has been found to attenuate the haematological, haemostatic, and histopathological alterations induced by ASA. Our findings collectively indicate that the gastroprotective effect of BV against ASA-induced ulceration in rats is mediated by its antioxidant, anti-inflammatory, anti-apoptotic, and anti-secretory properties.
