An inverse association between use of antiepileptic drugs (AEDs) and prostate cancer (PCa) has been suggested, putatively due to the histone deacetylases inhibitory (HDACi) properties of the AEDs. In a case-control study in Prostate Cancer data Base Sweden (PCBaSe), PCa cases diagnosed between 2014 and 2016 were matched to five controls by year of birth and county of residence. AED prescriptions were identified in the Prescribed Drug Registry. Odds ratios (ORs) and 95% confidence intervals for risk of PCa were estimated using multivariable conditional logistic regression, adjusted for civil status, education level, Charlson comorbidity index, number of outpatient visits, and cumulative duration of hospital stay. Dose responses in different PCa risk categories and HDACi properties of specific AED substances were further explored. 1738/31591 (5.5%) cases and 9674/156802 (6.2%) controls had been exposed to AED. Overall, users of any AED had a reduced risk of PCa as compared to nonusers (OR: 0.92; 95% CI: 0.87–0.97) which was attenuated by adjustment to healthcare utilisation. A reduced risk was also observed in all models for high-risk or metastatic PCa in AED users compared to nonusers (OR: 0.89; 95% CI: 0.81–0.97). No significant findings were observed for dose response or HDACi analyses. Our findings suggest a weak inverse association between AED use and PCa risk, which was attenuated by adjustment for healthcare utilisation. Moreover, our study showed no consistent dose-response pattern and no support for a stronger reduction related to HDAC inhibition. Further studies focusing on advanced PCa and PCa treatments are needed to better analyse the association between use of AED and risk of PCa. [ABSTRACT FROM AUTHOR]

Men with prostate cancer (PCa) on gonadotropin-releasing hormone agonists (GnRH) have an increased risk of cardiovascular disease (CVD) compared to men with PCa not on GnRH as well as compared with PCa-free men. Whether the addition of androgen receptor targeted (ART) drugs to GnRH further increases CVD risk, remains to be fully elucidated. We investigated risk of CVD for men with castration resistant PCa (CRPC) on GnRH plus ART; abiraterone or enzalutamide vs 5,127 and 12,079 respective matched comparator men on GnRH in Prostate Cancer data Base Sweden (PCBaSe
Traject ) 4.1 between 1 June 2015 and 31 December 2018. PCBaSeTraject links National Prostate Cancer Register of Sweden to other healthcare registries and demographic databases. We conducted multivariable Cox proportional hazard models adjusting for PCa risk category, Charlson comorbidity index (CCI), insulin or statin use, civil status, level of education, history of CVD events and number of CVD drugs, with any incident or fatal CVD as the outcome. 1,310 men were treated with abiraterone and 3,579 with enzalutamide. In multivariable analysis, CVD risk was increased in men on abiraterone (hazard ratio (HR): 1.19; 95% confidence interval (CI): 1.03–1.38) and in men on enzalutamide (HR: 1.10; 95% CI: 1.01–1.20). Men with a recent CVD (<12 months) including both men on ART as well as comparators had a much higher probability of a new CVD vs men with no prior CVD. CVD risk was mildly increased in men with PCa on GnRH plus abiraterone or enzalutamide vs comparator men on GnRH. Residual confounding and detection bias may at least partly explain this association.

Objective To assess whether higher mortality rates among individuals in motor vehicle crashes in areas with low population density depend on injury type and severity or are related to the performance of emergency medical services (EMS). Methods Prehospital and hospital deaths were studied in a population-based cohort of 41 243 motor vehicle crashes that occurred in Sweden between 1998 and 2004. The final multivariable analysis was restricted to 6884 individuals in motor vehicle crashes, to minimise the effects of confounding factors. Results Crude mortality rates following motor vehicle crashes were inversely related to regional population density. In regions with low population density, the unadjusted rate ratio for prehospital death was 2.2 (95% CI 1.9 to 2.5) and for hospital death 1.5 (95% CI 1.1 to 1.9), compared with a high-density population. However, after controlling for regional differences in age, gender and the type/severity of injuries among 6884 individuals in motor vehicle crashes, low population density was no longer associated with increased mortality. At 25 years of age, predicted prehospital mortality was 9% lower (95% CI 5% to 12%) in regions with low population density compared with high population density. This difference decreased with increasing age, but was still 3% lower (95% CI 0.5% to 5%) at 65 years of age. Conclusions The inverse relationship between population density and mortality among individuals in motor vehicle crashes is related to pre-crash factors that influence the type and severity of injuries and not to differences in EMS.

Background Classification of injuries and estimation of injury severity on the basis of ICD-10 injury coding are powerful epidemiological tools. Little is known about the characteristics and consequences of primary coding errors and their consequences for such applications. Materials and methods From the Swedish national hospital discharge register, 15 899 incident injury cases primarily admitted to the two hospitals in Uppsala County between 2000 and 2004 were identified. Of these, 967 randomly selected patient records were reviewed. Errors in injury diagnosis were corrected, and the consequences of these changes were analysed. Results Out of 1370 injury codes, 10% were corrected, but 95% of the injury codes were correct to the third position. In 21% (95% CI 19% to 24%) of 967 hospital admissions, at least one ICD-10 code for injury was changed or added, but only 13% (127) had some change made to their injury mortality diagnosis matrix classification. Among the cases with coding errors, the mean ICD-based injury severity score changed slightly (difference 0.016; 95% CI 0.007 to 0.032). The area under the receiver operating characteristics curve was 0.892 for predicting hospital mortality and remained essentially unchanged after the correction of codes (95% CI for difference -0.022 to 0.013). Conclusion Errors in ICD-10-coded injuries in hospital discharge data were common, but the consequences for injury categorisation were moderate and the consequences for injury severity estimates were in most cases minor. The error rate for detailed levels of cause-of-injury codes was high and may be detrimental for identifying specific targets for prevention. [ABSTRACT FROM AUTHOR]
