AI Article Synopsis

  • The study examines the link between oral health and the risk of gastric cancer (GC), acknowledging mixed findings in previous research.
  • It analyzes data from 1.4 million patients across various studies, concluding that poor oral health is indeed associated with an increased risk of GC, particularly highlighting periodontitis as a significant factor.
  • The research suggests that individuals with poor oral hygiene should be aware of their potential heightened risk for developing gastric cancer.

Article Abstract

Background: In recent years, the association between oral health and the risk of gastric cancer (GC) has gradually attracted increased interest. However, in terms of GC incidence, the association between oral health and GC incidence remains controversial. Periodontitis is reported to increase the risk of GC. However, some studies have shown that periodontitis has no effect on the risk of GC. Therefore, the present study aimed to assess whether there is a relationship between oral health and the risk of GC.

Aim: To assess whether there was a relationship between oral health and the risk of GC.

Methods: Five databases were searched to find eligible studies from inception to April 10, 2023. Newcastle-Ottawa Scale score was used to assess the quality of included studies. The quality of cohort studies and case-control studies were evaluated separately in this study. Incidence of GC were described by odds ratio (OR) and 95% confidence interval (CI). Funnel plot was used to represent the publication bias of included studies. We performed the data analysis by StataSE 16.

Results: A total of 1431677 patients from twelve included studies were enrolled for data analysis in this study. According to our analysis, we found that the poor oral health was associated with higher risk of GC (OR = 1.15, 95%CI: 1.02-1.29; = 59.47%, = 0.00 < 0.01). Moreover, after subgroup analysis, the outcomes showed that whether tooth loss (OR = 1.12, 95%CI: 0.94-1.29; = 6.01%, > 0.01), gingivitis (OR = 1.19, 95%CI: 0.71-1.67; = 0.00%, > 0.01), dentures (OR = 1.27, 95%CI: 0.63-1.19; = 68.79%, > 0.01), or tooth brushing (OR = 1.25, 95%CI: 0.78-1.71; = 88.87%, > 0.01) had no influence on the risk of GC. However, patients with periodontitis (OR = 1.13, 95%CI: 1.04-1.23; = 0.00%, < 0.01) had a higher risk of GC.

Conclusion: Patients with poor oral health, especially periodontitis, had a higher risk of GC. Patients should be concerned about their oral health. Improving oral health might reduce the risk of GC.

Objective: To explore the interventions for change in oral health behaviour that are effective in improving oral health behaviours in 8 to 18-year-old children during oral health promotion.

Methods: The Joanna Briggs Institute framework of evidence synthesis for conducting a scoping review was implemented for the methodology. Included studies related to the objective, measured clinical or non-clinical outcomes, were in English, 2011-2023, and were experimental, observational or reviews.

A hallmark of chronic and inflammatory diseases is the formation of a fibrotic and stiff extracellular matrix (ECM), typically associated with abnormal, leaky microvascular capillaries. Mechanisms explaining how the microvasculature responds to ECM alterations remain unknown. Here, we used a microphysiological model of capillaries on a chip mimicking the characteristics of healthy or fibrotic collagen to test the hypothesis that perivascular cells mediate the response of vascular capillaries to mechanical and structural changes in the human ECM.

Background: C3 glomerulopathy (C3G) is a rare disease affecting the complement alternative pathway, categorized into dense deposit disease and C3 glomerulonephritis. Dense deposit disease predominantly affects younger individuals, while C3 glomerulonephritis tends to manifest in older populations. The diseases are characterized by dysregulation of the complement alternative pathway, leading to the deposition of complement components in the glomeruli and subsequent renal dysfunction.

Purpose: Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that is essential for the survival and immune sequestration of cancer cells. We conducted a phase 1 study of TTI‑101, a first-in-class, selective small-molecule inhibitor of STAT3, in patients with advanced metastatic cancer.

Patients And Methods: Patients were treated with TTI-101 orally twice daily in 28-day cycles at 4 dose levels (DLs): 3.

Diabetes exacerbates periodontitis by overexpressing reactive oxygen species (ROS), which leads to periodontal bone resorption. Consequently, it is imperative to relieve inflammation and promote alveolar bone regeneration comprehensively for the development of diabetic periodontal treatment strategies. Furthermore, an orderly treatment to avoid interference between these two processes can achieve the optimal therapeutic effect.
