- Aims/hypothesis: Diabetes is associated with an increased risk of cancer. Prostasin is an epithelial sodium channel stimulator that has been associated with suppression of tumours, glucose metabolism and hyperglycaemia-associated tumour pathology. However, the association between prostasin, diabetes and cancer mortality has not been well investigated in humans. We aim to investigate the associations between plasma prostasin and diabetes, and to explore whether prostasin has an effect on cancer mortality risk in individuals with hyperglycaemia. Methods: Plasma prostasin was measured using samples from the Malmö Diet and Cancer Study Cardiovascular Cohort, and statistical analysis was performed from both sex-specific quartiles and per 1 SD. The cross-sectional association between plasma prostasin and diabetes was first studied in 4658 participants (age 57.5 ± 5.9 years, 39.9% men). After excluding 361 with prevalent diabetes, the associations of prostasin with incident diabetes and cancer mortality risk were assessed using Cox regression analysis. The interactions between prostasin and blood glucose levels as well as other covariates were tested. Results: The adjusted OR for prevalent diabetes in the 4th vs 1st quartile of prostasin concentrations was 1.95 (95% CI 1.39, 2.76) (p for trend <0.0001). During mean follow-up periods of 21.9 ± 7.0 and 23.5 ± 6.1 years, respectively, 702 participants developed diabetes and 651 died from cancer. Prostasin was significantly associated with the incidence of diabetes. The adjusted HR for diabetes in the 4th vs 1st quartile of prostasin concentrations was 1.76 (95% CI 1.41, 2.19) (p for trend <0.0001). Prostasin was also associated with cancer mortality There was a significant interaction between prostasin and fasting blood glucose for cancer mortality risk (p for interaction =0.022), with a stronger association observed in individuals with impaired fasting blood glucose levels at baseline (HR per 1 SD change 1.52; 95% CI 1.07, 2.16; p=0.019). Conclusions/interpretation: Plasma prostasin levels are positively associated with diabetes risk and with cancer mortality risk, especially in individuals with high blood glucose levels, which may shed new light on the relationship between diabetes and cancer.

- Objectives: Coronary artery calcium score (CACS) is a marker of subclinical atherosclerosis. However, there is little data related to the association between arterial stiffness and CACS in the general population. The aim of this study was to explore the association between carotid femoral-pulse wave velocity (c-f PWV), a widely accepted marker of arterial stiffness, and CACS. Methods: Participants with complete measurements on c-f PWV, CACS and confounding variables from the Swedish CArdioPulmonary biolmage Study (SCAPIS) cohort were included in the final study population (n=8725). CACS was divided into three categories (<10, >10 and <= 100, and >100) and multinomial logistic regression was performed to explore the association between these categories of CACS and quartiles of c-f PWV, and for per one standard deviation (SD) increment of c-f PWV. Results: CACS <= 10, >10 and <= 100, and >100 were present in 69.3, 17.8 and 12.9% of the study population, respectively. The odds ratio (OR) for CACS >100 for the fourth quartile (Q4) of c-f PWV vs. Q1 (reference category) was 1.62 (95% confidence interval [CI] 1.25-2.12) after adjustments. One standard deviation increase in c-f PWV was independently associated with a higher odds of having a CACS category >100 (OR: 1.25, 95% CI 1.14-1.36) in the final multivariable model. Conclusion: c-f PWV is positively associated with increased risk of higher CACS, and can be valuable in identifying individuals at risk for sub-clinical atherosclerosis.
