Introduction: Colorectal cancer (CRC) is a rising threat, necessitating accurate early diagnosis.

Aim: This meta-analysis scrutinised methylated septin 9 (SEPT9) and carcinoembryonic antigen (CEA) in CRC.

Methods: From January 2012 to December 2022, databases including PubMed and Google Scholar were explored for English publications.

Results: The meta-analysis revealed SEPT9's superior diagnostic potential, boasting 71% sensitivity and 91% specificity, outshining CEA (49% and 53%). Notably, an 8-study analysis found a positive correlation between tumour grade and elevated CEA and SEPT9 levels, particularly in stages 3 and 4.

Conclusions: This meta-analysis supports SEPT9 as a potent CRC marker, urging its integration into diagnostic frameworks for enhanced precision and early intervention. The observed link between tumour grade and biomarker levels enhances clinical relevance. Implementing these findings promises improved CRC diagnosis precision, contributing to enhanced treatment outcomes and patient survival. Advocating for SEPT9's inclusion alongside traditional markers like CEA, this study pioneers more effective colorectal cancer management strategies.

Introduction: Primary sclerosing cholangitis (PSC) is an uncommon, chronic liver disease characterised by fibrosis and strictures of a bile ducts, causing cholestasis. In the long term it can lead to complete stenosis leading in turn to liver cirrhosis. In patients with severe form of the disease, the recommended treatment is liver transplantation. Because PSC frequently coexists with ulcerative colitis (UC), it is crucial to determine the effect of liver transplantation on the course of UC.

Aim: The aim was to determine the impact of liver transplantation on intestinal and systemic inflammation markers with UC concomitant with PSC (PSC-UC).

Material and methods: Sixty-three patients with PSC-UC were enrolled, 25 of whom underwent liver transplantation (OLTx) due to PSC progression. Clinical symptoms, faecal calprotectin levels, C-reactive protein (CRP) serum concentration, erythrocyte sedimentation rate, and white blood cell count (WBC) were obtained.

Results: Faecal calprotectin was significantly higher in the post-OLTx group. Mean calprotectin values were 163% higher - 474 ng/ml and 180 ng/ml (p = 0.024) in the post-OLTx group and in the PSC-UC group without the transplantation, respectively. Calprotectin levels exceeded the upper limit of normal (defined as 200 ng/l) in 66% of liver recipients and in 18% of non-transplanted patients (OR = 9.33, p = 0.011). In the post-OLTx group, also CRP concentration (11.01 mg/l vs. 6.54 mg/l, p = 0.30) and WBC (7.58 K/ml vs. 5.72 K/ml, p = 0.006) were higher than in the PSC-UC group without transplantation.

Conclusions: We found significantly higher inflammation markers in PSC-UC patients who underwent liver transplantation due to PSC. The effect was strongest in faecal calprotectin levels. In PSC-UC patients after liver transplantation, intensification of UC treatment may be needed, despite the lack of worsening of clinical symptoms.

Introduction: The gut microbiome maintains the mucus membrane barrier's integrity, and it is modulated by the host's immune system.

Aim: To detect the effect of microbiota modulation using probiotics, prebiotics, symbiotics, and natural changes on colorectal cancers (CRCs).

Methods: A PubMed search was conducted to retrieve the original and in vivo articles published in English language from 2010 until 2021 containing the following keywords: 1) CRCs, 2) CRCs treatment (i.e. surgical, chemotherapy, radiotherapy and/or immunotherapy), and 3) microbiota probiotic(s), prebiotic(s), symbiotic(s), dysbiosis and/or nutritional treatment. A total of 198 PubMed records/articles were initially identified. 108 articles were excluded at the initial screening, and another 29 articles were excluded after reviewing the abstracts, and finally 61 studies were analysed for this systematic review.

Results: The gut microbiota metabolites and (SCFAs) short-chain fatty acids (i.e. acetate and butyrate) have a protective effect against CRCs. SCFAs reduce the inflammatory cytokines, inhibit colonocyte proliferation, and promote malignant cell apoptosis. Butyrate maintains the integrity of the mucus membrane barrier and reduces intestinal mucosal inflammation. Reduced butyric acid level and increased inflammatory cytokines were observed after reduced Bacteroides fragilis and Bacteroides vulgatus species in the colon. Akkermansia muciniphila bacterium decreased in patients with CRCs.

Conclusions: Prebiotics (i.e. inulin and resistant starch, SCFAs producers) and consumption of unprocessed plant products are useful for developing and maintaining healthy gut microbiota. The pro-, pre- and/or symbiotics may be useful when carefully selected for CRC patients, to restore beneficial gut microbiota and support treatment efficacy.

Introduction: Growing adoption of endoscopic procedures in clinical practice has gradually increase the detection rate of gastric polypoid lesions.

Aim: To identify the epidemiologic characteristics of gastric polyps as well as changes of these parameters during a 15-year period.

Material and methods: We reviewed all the upper endoscopies archived in our database reporting a polypoid lesion from 2003 to 2018. Demographic data, indication for endoscopy, morphological characteristics of polyps, histology, and presence of Helicobacter pylori were collected. We compared the abovementioned data between 2 periods: 2003-2010 and 2010-2018.

Results: A total of 989 (4.2%) patients from 23,668 reviewed were identified to harbour a polypoid lesion. Mean patient age was 63.2 years, with 58.8% being female. Most polyps (65.2%) were less than 5 mm in diameter and located in the fundus. Hyperplastic polyps (HPs) were the predominant type (28.6%) while fundic gland polyps (FGPs) were found in 24.1% of patients. Adenomas were the least common type (2.7%). Other pathology was identified in 43.3%. Comparison between the 2 periods revealed a rise of FGPs against HPs with a concomitant shift of location from antrum to fundus and an increase in the number of polyps per patient.

Conclusions: FGPs and HPs were the most common polyps found in our cohort, with a change of their pattern during the 15 years. It is imperative to acknowledge the distinct characteristics of gastric polyps so as to properly assess the malignant potential that some of them, or their surrounding gastric mucosa, harbour.

Introduction: The eradication rate of Helicobacter pylori (H. pylori) has decreased due to antibiotics resistance and inadequate acid suppression. Vonoprazan is a novel potassium-competitive acid blocker (P-CAB), which has a rapid and sustained acid inhibitory effect and may be more effective than conventional proton pump inhibitors (PPIs) in H. pylori eradication.

Aim: to study the efficacy and safety of vonoprazan as a component of first-line H. pylori eradication treatment compared with conventional PPI-based therapy.

Material and methods: This randomised (one to one) non-blinded study was conducted on 400 consecutive proven H. pylori infected patients, of whom 200 received vonoprazan-based triple therapy, while 200 patients received PPI-based triple therapy for 14 days. The study outcomes were evaluated as eradication rate and adverse events in both patient groups.

Results: The eradication rate was 86% in the vonoprazan group and 74.5% in the PPI group. The vonoprazan eradication rate was significantly higher than that of PPIs (p = 0.004). There was no significant difference regarding adverse events between both patient groups.

Conclusions: Vonoprazan-based therapy was more effective than PPI-based therapy as a first-line H. pylori eradication treatment. Vonoprazan was generally safe and well tolerated.

Plantago ovata is a common medicinal plant widely cultivated in tropical regions of the world. The outer seed coat of P. ovata, obtained by cleaning the seeds, contains soluble and insoluble fibre in a ratio of 7:3, making products containing P. ovata husk an ideal source of health-beneficial fibre. The results of clinical trials demonstrate the therapeutic efficacy of psyllium husk for various gastrointestinal disorders. It has also been documented that psyllium ingestion exhibits antioxidant, immunomodulatory, antiproliferative, anticancer, and antiviral effects. Such pleiotropic effects of P. ovata husk are related to the presence in its composition of arabinoxylan, which forms a gel in an aqueous environment, as well as bioactive compounds and their metabolites. This article presents the evidence available in the literature on the therapeutic potential and possible mechanisms of action of psyllium in the treatment of irritable bowel syndrome and ulcerative colitis, and prevention of colorectal cancer.

Introduction: Exercise is a simple, safe, and affordable solution that can be easily taught to men with chronic illnesses to improve their psychological burden and sexual health.

Aim: Since the role of exercise in ameliorating the psychological burden associated with erectile dysfunction (ED) in hepatitis C (HC) men was not explored, this research aimed to explore this role.

Material and methods: This HC study was a randomized-controlled exercise-rehabilitation trial. Recruitment of HC men with ED was conducted from El-Sahel Teaching Hospital, Cairo, Egypt. Men (n = 46) were randomly assigned to a 12-week walking-exercise group (WEG, n = 23 HC men with ED received a 1-hour treadmill walking 3 times weekly) or a control group (n = 23 HC men with ED, who did not change their daily physical activity during the research period). Besides Beck's Depression Inventory (BDI), Arabic Version of the Five-Item Version International Index of Erectile Function (IIEF-5), Profile of Mood States Questionnaire (POMSQ), and Ten-Statement Rosenberg self-esteem scale (TSRSE), HC participants' liver enzymes, alanine transaminase (ALT), and aspartate transaminase (AST) were assessed.

Results: Significant improvements of POMSQ, BDI, AST, IIEF-5, ALT, and TSRSE within the WEG only were seen. No significant changes occurred in the control group's parameters.

Conclusions: Exercise (walking) is a good modality to improve liver enzymes, ED, and ED-associated psychological burden (depression, low self-esteem, and mood disturbances) in HC men with ED.

Patients with liver cirrhosis constitute a critically ill and unique population, and their stability relies on a well-coordinated multidisciplinary team with a carefully structured plan. Overlooking any aspect of this plan can expedite disease progression, leading to severe complications. The lack of disease-specific nutritional guidance, the prevalent sedentary lifestyle among patients, and insufficient screening for hepatocellular carcinoma, oesophageal varices, sarcopaenia, minimal hepatic encephalopathy, and diabetes mellitus, along with fibrosis progression and cirrhosis decompensation, can add further complexities. Additionally, devaluing the impact of obesity in triggering liver cirrhosis can be disadvantageous. Prolonged and inappropriate use of proton pump inhibitors also poses a significant challenge with a wide range of complications. These often-unheeded aspects in the care of liver cirrhosis patients represents the unseen culprits of progression from bad to worse and warrant serious consideration.
