AI Article Synopsis
- Glycemic disorders, particularly prediabetes, have been investigated for their potential link to the risk of pancreatic cancer, which has primarily focused on diabetes in past studies.
- A meta-analysis of nine cohort studies involving over 26 million participants revealed that individuals with prediabetes had a significantly higher incidence of pancreatic cancer compared to those with normal blood sugar levels.
- The results suggest that even in the absence of diabetes, prediabetes is associated with an increased risk of developing pancreatic cancer, and this association remains consistent across various study characteristics.
Article Abstract
Background: Glycemic disorder is closely related to the risk of pancreatic cancer, but previous studies focused on the influence of diabetes. The aim of this meta-analysis was to investigate the influence of prediabetes, an intermediate state between normoglycemia and diabetes, on the risk of pancreatic cancer.
Methods: Relevant longitudinal observational studies were identified through a search of Medline, Embase, and Web of Science databases. To minimize the influence of between-study heterogeneity, a randomized-effects model was used to pool the results.
Results: Nine cohort studies including 26,444,624 subjects were available for the meta-analysis. Among them, 2,052,986 (7.8%) had prediabetes at baseline, and the participants were followed for a mean duration of 5.9 years. It was found that, compared to people with normoglycemia, those with prediabetes had a higher incidence of pancreatic cancer (risk ratio [RR]: 1.42, 95% confidence interval: 1.36 to 1.49, p<0.001) with no statistical heterogeneity (I2 = 0%). Sensitivity analysis performed by excluding one dataset at a time did not significantly change the results (RR: 1.38 to 1.45, p all <0.05). Subgroup analyses indicated that the association between prediabetes and increased risk of pancreatic cancer was not significantly impacted by study characteristics such as study design, location, age, and sex of participants, definition of prediabetes, duration of follow-up, or adjustment for alcohol intake (p for subgroup difference all >0.05).
Conclusions: Prediabetes may be associated with an increased risk of pancreatic cancer compared to normoglycemia.

The outbreak of COVID-19 has opened up new avenues for exploring the importance of vitamin D in immunity, in addition to its role in calcium absorption. Recently, vitamin D supplementation has been found to enhance T regulatory lymphocytes, which are reduced in individuals with COVID-19. Increased risk of pneumonia and increases in inflammatory cytokines have been reported to be major threats associated with vitamin-D deficiency.

Serous cystadenoma (SCA) of the pancreas is a benign nonmucinous cystic pancreatic neoplasm and the second most common type of pancreatic cystic neoplasm. Conservative management is advocated in asymptomatic cases as they have indolent clinical behavior and risk for postoperative morbidity, making an exact diagnosis essential. Morphologically, serous cystadenoma has a prominent subepithelial capillary meshwork causing the aspirate to be paucicellular and nondiagnostic.

Background: Despite efforts to ensure equitable access to liver transplantation (LT), significant disparities remain. Although prior literature has considered the effects of patient sex, race, and income, the contemporary impact of community socioeconomic disadvantage on outcomes after waitlisting for LT remains to be elucidated. We sought to evaluate the association of community-level socioeconomic deprivation with survival after waitlisting for LT.
