Sitafloxacin showed MICs of less than or equal to 0.5 microg/ml against 105 isolates of Helicobacter pylori, including 44 isolates with mutations in the gyrA gene. The highest MICs for garenoxacin and levofloxacin were 8 and 64 times, respectively, higher than the highest MICs observed for sitafloxacin.

Oxyntic gland neoplasms typically arise in Helicobacter pylori-naïve stomachs and are composed predominantly of chief cells, with a smaller component of parietal cells. The pathologic diagnosis can be challenging due to minimal cellular atypia. Especially in biopsy specimens with limited tumor volume or when pathologists have limited experience in diagnosing this neoplasm, distinguishing it from normal oxyntic glands can be difficult, and no reliable diagnostic markers are currently available.

Background: Previous investigations into the causal relationship between infections and systemic lupus erythematosus (SLE) have yielded controversial results. This study delves into the bidirectional causal relationships between various infectious agents and SLE, employing two-sample Mendelian randomization (MR) from an immunological perspective.

Methods: Utilizing genome-wide association study (GWAS) data for 46 antibody-mediated immune responses (AMIRs) to 13 pathogens and three distinct SLE datasets, we employed Bayesian Weighted MR (BWMR) and inverse variance weighted (IVW) methods to ascertain causal links, supplemented by meta-analysis to resolve inconsistencies.

Background: Intestinal-type gastric cancer (IGC) and diffuse-type gastric cancer (DGC) exhibit different prevalence rates between sexes. While environmental factors like Helicobacter pylori infection and alcohol consumption contribute to these differences, they do not fully account for them, suggesting a role for host genetic factors.

Methods: We conducted a meta-analysis to explore associations between single nucleotide polymorphisms (SNPs) and the risk of IGC or DGC.
