Barrett's esophagus (BE) is a premalignant columnar metaplasia of the esophagus that predisposes victims to esophageal adenocarcinoma (EAC). Depending on differences in the study population and risk factors, the prevalence of BE may vary, from 0.4 to 20% globally. The current study aimed to systematically review and analyse the prevalence of BE in in patients with gastrointestinal symptoms in Iran. Furthermore, gastrointestinal malignancies are among the most common tumours in Iran, making this study even more significant.

We aimed to evaluate the efficacy of the log odds of positive lymph nodes (LODDS) in survival prediction of elderly patients with gastric adenocarcinoma (GAC) after gastrectomy, and to construct a relevant survival prediction model.

E-cadherin, encoded by the CDH1 gene, plays an essential role in epithelial cellular adhesion, and the loss of it has been reported to be associated with tumor progression and metastasis, potentially offer a glimpse in to the development of colorectal cancer. The present study aimed to explore effect of CDH1-160 polymorphism, CDH1 transcription and its protein E-cadherin expression on colorectal cancer, meanwhile uncovering the underlying mechanism. Specimens from cancer loci, adjacent cancer tissue, and distal normal tissue from colorectal cancer patients were collected for Hematoxylin-eosin staining to detect the histopathological change of colorectal mucosa. Direct sequencing and Quantitative Real-Time PCR were used to detect the CDH1 genotype and its mRNA expression, respectively. E-cadherin expression was detected using the ElivisionTM plus method. As a result, we found that the A allele of the CDH1-160 may be a protective gene against colorectal cancer, and the C > A polymorphism may regulate its transcription activity and expression of E-cadherin. The decrease of the CDH1 mRNA transcription level and the absence of E-cadherin on the cytomembrane may promote intestinal mucosal carcinogenesis and accelerate cancer cell metastasis. Deficiency of cytomembrane expression of E-cadherin protein may have some early warning signs for malignant lesions of the gut mucosa.

Total neoadjuvant treatment (TNT) has become a standard treatment approach for locally advanced rectal cancer (LARC). Patients achieving pathological complete response (pCR) following TNT have better outcomes (overall survival, relapse free survival). However, not all patients treated for LARC with neoadjuvant treatment achieve pCR.

To evaluate the value of the modified Asia-Pacific colorectal cancer screening (APCS) scoring system combined with fecal occult blood test (FOBT) for colorectal cancer (CRC) screening in asymptomatic population of Wannan region.

Percutaneous transhepatic bile duct stent insertion is a useful alternative to the endoscopic approach for malignant biliary strictures. This study retrospectively reviewed the cases of percutaneous metallic stent insertion at our institution to evaluate its safety and usefulness.

The study focused on identifying risk factors for organ-space surgical site infections (SSIs) in patients undergoing minimally invasive rectal cancer surgery and examining the impact of these infections on oncological outcomes.

This study aimed to decipher the intricate interplay between the immune landscape and CRC pathogenesis, elucidating how distinct immunophenotypes causally influence disease susceptibility and stratify patient outcomes.

Antibiotics are currently the primary treatment of Clostridioides difficile (C. difficile) infection. Yet, due to rapid development of resistance and high recurrences rates, there is an unmet need for new antimicrobials for C. difficile infections. This study assessed the in vitro susceptibility of clinical isolates from Israel to two recently developed antibiotics, ridinilazole (RDZ) and ibezapolstat (IBZ), and to standard-of-care antibiotics.

Helicobacter pylori (H. pylori) infection is the main cause of the most frequent gastroduodenal diseases and gastric atrophy, with or without intestinal metaplasia, which predisposes to gastric cancer development. Gastric juice analysis may be useful in diagnosing these conditions, revealing the H. pylori infection and hypochlorhydria status by measuring ammonium concentrations and pH levels. EndoFaster® is a device introduced to perform these analyses on gastric juice in real-time. The available data showed very high negative predictive values in ruling out the infection and corpus atrophic gastritis, thereby potentially reducing the need for gastric biopsies when test results are negative. This review aims to assess the potential role of EndoFaster® in supporting the diagnosis of H. pylori infection, detecting gastric precancerous lesions, and other specific clinical applications, potentially reducing unnecessary gastric biopsies.

Advanced liver disease is a global health challenge which requires a timely and accurate diagnosis for optimal patient management. Traditionally, liver biopsy has been the gold standard for diagnosing and staging liver diseases; however, its invasiveness and associated risks, including bleeding, infection, and sampling errors, limit its utility. Non-invasive tests (NITs) have emerged as critical tools in liver disease evaluation, offering safe and effective alternatives to biopsy. This review explores the spectrum of NITs, highlighting their benefits, limitations, and clinical applications in specific liver diseases. NITs have demonstrated significant utility in monitoring chronic viral hepatitis, metabolic-associated steatotic liver disease (MASLD), and cholestatic liver diseases, reducing the need for invasive procedures. While further refinement and validation are needed, NITs represent a major advancement in liver disease management, enhancing early diagnosis, monitoring treatment response, and improving patient outcomes. This review delves into the various non-invasive tests employed in liver disease evaluation, emphasizing their benefits, limitations, and clinical applications. By examining the current landscape of NITs, we aim to elucidate how these advancements are revolutionizing the diagnosis and management of liver diseases, ultimately enhancing patient care and outcomes.

Artificial intelligence (AI) will fundamentally improve how we perform clinical trials by addressing issues of standardizing disease scoring, improving the sensitivity and precision of activity and phenotype assessments, and automating laborious and time-consuming study functions. Progress in AI image analysis is quickly proving to replicate expert judgment in endoscopy, histology, and cross-sectional imaging with speed, reproducibility, and reduced bias. However, AI analytics offer the ability to quantify disease characteristics with more detail and precision than human experts. Large language models and generative AI are automating the collection of high-quality data from electronic records and improving our ability to predict patient outcomes. This narrative review will focus on AI tools available today, their expected implementation, and future-facing opportunities for AI to reimagine inflammatory bowel disease clinical trials.

Immunotherapy has shown promising results in cancer treatment; however, it remains largely ineffective for pancreatic ductal adenocarcinoma (PDAC). N6-methyladenosine (m6A), known for its crucial role in cancer biology, is not yet fully understood regarding immune evasion. This study aims to elucidate the associations and mechanisms linking m6A modification with immune evasion in PDAC and propose strategies for clinical intervention.

Nonalcoholic fatty liver disease (NAFLD) with liver fibrosis is associated with liver-related mortality and cardiovascular disease. Estimated glucose disposal rate (eGDR), which is an insulin resistance-related index, is related to the mortality caused by NAFLD. This study aimed to investigate the predictive value of eGDR for liver fibrosis in patients with NAFLD.

Gallstones are a common disease that imposes a significant burden on public health resources. Sarcopenia is an age-related condition characterized by a decline in muscle mass, strength, and function. However, its relationship with gallstones remains unclear.
