Background: Non-alcoholic fatty liver disease (NAFLD) is an increasingly common cause of chronic liver disease and is becoming a major public health problem. NAFLD has been recognized as a hepatic manifestation of metabolic syndrome, associated with systemic diseases such as cardiovascular disease (CVD) and chronic kidney disease (CKD).

Objective: The aim of this study was to examine the role of serum LFT parameters and renal function parameters as predictors of unmanifested liver disease.

(CD) is a spore-forming bacterium that causes life-threatening intestinal infections in humans. Although formerly regarded as exclusively nosocomial, there is increasing genomic evidence that person-to-person transmission accounts for only <25% of cases, supporting the culture-based hypothesis that foods may be routine sources of CD-spore ingestion in humans. To synthesize the evidence on the risk of CD exposure via foods, we conducted a systematic review and meta-analysis of studies reporting the culture prevalence of CD in foods between January 1981 and November 2019.

Background: Various complications occur in patients with advanced stages of liver diseases. Renal dysfunction, a parameter included in the MELD score, is the most important prognostic factor. There is a strong need in clinical practice to estimate the GFR in this patients.

Article Synopsis
  • - The study focused on evaluating the effectiveness of two tumor markers, CEA and CA 19-9, in diagnosing and staging colon cancer, particularly emphasizing their role in patients with metastatic disease.
  • - Conducted on 91 patients with confirmed colon adenocarcinoma, the research found that those with metastases had significantly higher levels of CEA and CA 19-9, especially in older individuals.
  • - The findings concluded that while CEA and CA 19-9 are useful for assessing advanced colon cancer, they become more evident in the presence of established metastases, indicating their role as late markers in cancer progression.

Introduction: Ulcerative colitis (UC) is a common disease with a chronic and relapsing presentation requiring regular clinical follow up. Epidemiological and microbiologic studies suggest that enteropathogenic microorganisms play a substantial role in the clinical presentation and extent of inflammatory bowel disease.

Goal: To evaluate the presence of intestinal infections by Entamoeba hystolitica in patients with ulcerative colitis, their impact on clinical outcome, and to identify associated risk factors.

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the digestive tract. The majority of GISTs are located in the stomach. Only 3-5% of GISTs are located in the duodenum associated with an increased risk of gastrointestinal bleeding as primary manifestation.

Introduction: Colorectal cancer is the third most common tumor which causes high percentage of mortality in the general population. Etiologic factors which cause this disease are various, while diagnostic methods involve very complex protocols from detection of tumor markers to a combination of endoscopic and imaging methods.

Goal: To determine the number of patients suffering from colon cancer for a period of two years and with endoscopic methods to verify and localize the tumor and its spread.

Introduction: Infection with hepatitis C is often manifested by a mild clinical course, and in many patients it is revealed incidentally, during routine laboratory ests. Progression of the disease often takes 10-20 years with specified high risk of fibrosis and hepatocellular carcinoma.

Material And Methods: The group of subjects with chronic liver disease of viral C etiology was consisted of 50 patients of both sexes, 38 (75%) were male and 13 (25%) females, aged 20-65 years.
