However, estimates of the relative risks (RRs) of PD and the roles of genetic and environmental factors in PD susceptibility are unclear. The aim of this study was to examine familial aggregation and genetic contributions to PD and the RRs of other neuropsychiatric diseases in relatives of PD patients. Methods: In this population-based family cohort study, the records of all individuals actively registered in the Taiwan National Health Insurance Research Database in 2015 were queried (N=24,349,599). In total, 149,187 individuals with a PD-affected parent, 3,698 with an affected offspring, 3,495 with an affected sibling, and 15 with an affected twin were identified. Diagnoses of PD were ascertained between January 1, 1999, and December 31, 2015. The prevalence and RRs of PD and other neuropsychiatric diseases in individuals with first-degree relatives with PD, as well as the contributions of heritability and environmental factors to PD susceptibility were investigated. Results: The prevalence of PD was 0.46% in the general population and 0.52% in individuals with f

The National Health Insurance database of Taiwan was explored for patients who received liver transplantation without pre-transplant diabetes from 1998 to 2012. Information regarding clinical conditions and immunosuppressant utilization among these patients was analyzed statistically. Of the 2,140 patients included in our study, 189 (8.8%) developed NODALT. The pre-transplant risk factors for NODALT were identified as old age, male sex, hepatitis C, alcoholic hepatitis, and immunosuppressant use of tacrolimus (TAC). All patients used corticosteroids as a baseline immunosuppressant. The immunosuppressant regimen of cyclosporine (CsA)+TAC+mycophenolate mofetil (MMF) contributed most to NODALT (adjusted hazard ratio 7.596) in comparison with the regimens of TAC+MMF and CsA+MMF; this regimen also contributed significantly to higher post-transplant bacteremia, urinary tract infection, pneumonia, renal failure, and mortality rate. In conclusion, our analysis confirmed TAC-based immunosuppression contributes to higher NODALT incidence than CsA-based regimen, and TAC-CsA conversion due to any causes might lead to worse clinical outcomes. Clinicians should make better risk stratifications before prescribing immunosuppressants for liver transplant recipients.
