Current Helicobacter Pylori Diagnostics
Helicobacter pylori (H. pylori) is one of the most common human pathogens and a leading etiological factor for various gastroduodenal diseases, including chronic gastritis, peptic ulcers, gastric adenocarcinoma, and MALT lymphoma. According to the latest systematic review with meta-analysis, 44.3% (95% CI: 40.9–47.7) of the global population are infected with this microorganism. Timely diagnosis and subsequent eradication of H. pylori in adults allows one to resolve inflammatory changes in the gastric mucosa and prevent the development of precancerous conditions (atrophic gastritis and intestinal metaplasia).

Nanomedicine in Clostridioides difficile Infection
Clostridioides difficile, a spore-forming bacterium, is a nosocomial infectious pathogen which can be found in animals as well. Although various antibiotics and disinfectants were developed, C. difficile infection (CDI) remains a serious health problem. C. difficile spores have complex structures and dormant characteristics that contribute to their resistance to harsh environments, successful transmission and recurrence.

Drug Targeting of IBD
Inflammatory bowel diseases (IBD) are disabling, noncommunicable, progressive and incurable immune-mediated inflammatory diseases (IMIDs). Crohn’s disease (CD) and ulcerative colitis (UC) constitute the most prevalent forms of IBD. These diseases are highly prevalent worldwide, particularly in Europe and North America, and are spreading globally at an accelerated rate.

Neurotransmitter Dysfunction in IBS
Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder whose aetiology is still unknown. Most hypotheses point out the gut-brain axis as a key factor for IBS. The axis is composed of different anatomic and functional structures intercommunicated through neurotransmitters.

Endoscopic Bariatric and Metabolic Therapies
Obesity is a chronic disease that is becoming increasingly more prevalent and is associated with many health problems, such as metabolic syndrome. The treatment options for obese patients include lifestyle modification, medications, endoscopic bariatric and metabolic therapies (EBMTs), and surgery. In particular, EBMTs have an excellent therapeutic effect and are less invasive than bariatric surgery.

Leaky Gut and Fatty Liver
Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and the leading cause of chronic liver disease in pediatric and adult populations living in industrialized countries. NAFLD encompasses steatosis and nonalcoholic steatohepatitis (NASH), and it is characterized by perivenular and lobular inflammation. Progression to fibrosis and cirrhosis are the primary complications of NAFLD. Based on a recent meta-analysis, one in four people in Europe, the United States, and Asia have NAFLD.

Diagnosis of Helicobacter pylori Infection
Helicobacter pylori (H. pylori) infects approximately 50% of the world population. Its infection is associated with gastropathies, extra-gastric digestive diseases, and diseases of other systems. There is a canonical process from acute-on-chronic inflammation, chronic atrophic gastritis (CAG), intestinal metaplasia (IM), dysplasia, and intraepithelial neoplasia, eventually to gastric cancer (GC). H. pylori eradication abolishes the inflammatory response and early treatment prevents the progression to preneoplastic lesions.

Surgical Techniques for Rectal Prolapse
Complete rectal prolapse or rectal procidentia is a debilitating disease that presents with fecal incontinence, constipation, and rectal discharge. Definitive surgical techniques described for this disease include perineal procedures such as mucosectomy and rectosigmoidectomy, and abdominal procedures such as rectopexy with or without mesh and concomitant resection. The debate over these techniques regarding the lowest recurrence and morbidity rates, and the best functional outcomes for constipation or incontinence, has been going on for decades. The heterogeneity of available studies does not allow us to draw firm conclusions.

TGR5
Takeda G protein-coupled receptor (TGR5) is a metabolic regulator, which is also involved in inflammatory responses. TGR5 belongs to the G protein-coupled receptor (GPCR) superfamily.

Rheumatoid Arthritis and Prevotella copri
Rheumatoid arthritis (RA) is a debilitating disease caused by several factors, which have only been partially identified. Globally approximately 0.24% of people are affected by RA, with women being more affected than men. The gastrointestinal tract is an essential getaway for the intake of favorable and harmful microbes and their metabolites through food and drinks. The imbalance of gut microbiota can cause gut dysbiosis, which is caused by an abundance of Prevotella copri. In recent years there have been reports citing Prevotella copri as the causative organism for RA, but there also have been reports contradicting the above findings. This topical review attempts to bring the two viewpoints together and find common ground for a rational hypothesis.
