Helicobacter pylori, a type of gram-negative bacterium, infects roughly half of the global population. It is strongly associated with gastrointestinal disorders like gastric cancer, peptic ulcers, and chronic gastritis. Moreover, numerous studies have linked this bacterium to various extra-gastric conditions, including hematologic, cardiovascular, and neurological issues. Specifically, research has shown that Helicobacter pylori interacts with the brain through the microbiota-gut-brain axis, thereby increasing the risk of neurological disorders. The inflammatory mediators released by Helicobacter pylori-induced chronic gastritis may disrupt the function of the blood-brain barrier by interfering with the transmission or direct action of neurotransmitters. This article examines the correlation between Helicobacter pylori and a range of conditions, such as hyperhomocysteinemia, schizophrenia, Alzheimer's disease, Parkinson's disease, ischemic stroke, multiple sclerosis, migraine, and Guillain-Barré syndrome.

University of Connecticut, Connecticut, USA.
Marginal ulcers are a common complication following Roux-en-Y bypass surgeries with an approximate incidence of 4.6%. The pathophysiology is complex and risk factors include smoking, nonsteroidal anti-inflammatory drugs (NSAIDs) use, Helicobacter pylori infection, and a larger pouch size.

Background: Gastrointestinal infections caused by intestinal parasites and Helicobacter pylori are significant public health issues in Africa, where poor sanitation and limited access to healthcare contribute to high disease burden. Since there was no previous pooled data regarding the intestinal parasites and Helicobacter pylori co-infections among gastrointestinal symptomatic patients in the African context, this review aimed to determine the overall prevalence of intestinal parasites and Helicobacter pylori co-infection in people with gastrointestinal symptoms in Africa.
Methods: The current review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards and registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42024598993).
Design, synthesis, in vitro, and in silico studies of 4-fluorocinnamaldehyde based thiosemicarbazones as urease inhibitors.

Clinically significant problems such as kidney stones and stomach ulcers are linked to the activation of the urease enzyme. At low pH, this enzyme gives an ideal environment to Helicobacter pylori in the stomach which is the cause of gastric ulcers and peptic ulcers. In recent work, we have developed a library of 4-fluorocinnamaldehyde base thiosemicarbazones and assessed them for their potential against urease enzyme.

Background: The Triglyceride-glucose (TyG) index is a marker for insulin resistance and metabolic syndrome, while Helicobacter pylori is linked to gastrointestinal diseases and may affect metabolic risks. This study examined the association between the TyG index and H. pylori infection in adults.

Background: The brain is shielded from the peripheral circulation by central nervous system (CNS) barriers, comprising the well-known blood-brain barrier (BBB) and the less recognized blood-cerebrospinal fluid (CSF) barrier located within the brain ventricles. The gut microbiota represents a diverse and dynamic population of microorganisms that can influence the health of the host, including the development of neurological disorders like Alzheimer's disease (AD). However, the intricate mechanisms governing the interplay between the gut and brain remain elusive, and the means by which gut-derived signals traverse the CNS barriers remain unclear.
