Objective: The aim of this study was to evaluate whether there is an association between Parkinson’s
disease (PD) and colorectal cancer in Taiwan. Methods: This was a case-control study using claim
data of the Taiwan National Health Insurance Program. There were 64,619 subjects aged 20-84 with
newly diagnosed colorectal cancer as cases and 64,619 randomly selected subjects without colorectal
cancer as controls from 2005 to 2011. Both cases and controls were matched by sex, age, comorbidities,
and index year of diagnosing colorectal cancer. Subjects who were diagnosed with PD within 5 years
of diagnosing colorectal cancer were excluded. The multivariable logistic regression model was used
to estimate the adjusted odds ratio (OR) and 95% confidence interval (95% CI) for risk of colorectal
cancer associated with PD. Results: After adjusting for confounding factors, the multivariable logistic
regression analysis revealed that the adjusted OR of colorectal cancer was 0.69 for subjects with PD
more than 5 years before index date (95% CI 0.59, 0.81), as compared with subjects without PD.
Conclusion: PD is associated with reduced odds of colorectal cancer. Further research is needed to
elucidate the mechanisms underlying our findings.

Background: The aim of this study was to investigate whether there is a relationship between
Parkinson’s disease and pancreatic cancer in Taiwan. Methods: This was a case-control study using
claim data of the Taiwan National Health Insurance Program. There were 13,861 subjects aged 20-
84 with newly diagnosed pancreatic cancer as cases and 55,444 randomly selected subjects without
pancreatic cancer as controls from 1998 to 2011. Cases and controls were matched by sex, age and
index year of diagnosing pancreatic cancer. The association of pancreatic cancer with Parkinson’s
disease was evaluated by the multivariable logistic regression model to estimate the adjusted odds
ratio (OR) and 95% confidence interval (95% CI). Results: After adjusting for confounding factors
including acute pancreatitis, chronic pancreatitis, diabetes mellitus, biliary stone, alcoholism, hepatitis
B and hepatitis C, the multivariable logistic regression analysis showed the adjusted OR of pancreatic
cancer was 0.82 for subjects with Parkinson’s disease (95% CI 0.55, 1.21), as compared with subjects
without Parkinson’s disease.
Conclusion: No association is detected between Parkinson’s disease and pancreatic cancer.

INTRODUCTIONLittle was known about the association between colorectal adenomas and cardiovascular risk factors in Taiwan. The aim of this study was to assess the association between rectosigmoid adenomas and related factors.
MATERIALS AND METHODSThis was a hospital-based, cross-sectional study. We analysed subjects receiving self-referred health examinations at 1 medical centre in Taiwan between 2001 and 2004. In total, 4413 subjects were enrolled in this study. There were 2444 men (55.4%) and 1969 women (44.6%). The mean age was 49.3 +/-12.3 years (range, 20 to 87). All subjects underwent a 60-cm flexible sigmoidoscopic examination and laboratory survey. Adjusted odds ratio (OR) and 95% confidence interval (CI) were expressed using a multivariate logistic regression analysis.
RESULTSIn the fi nal model, increasing age (OR, 1.05; 95% CI, 1.03-1.06), hypertriglyceridemia (OR, 1.49; 95% CI, 1.07-2.07), and alcohol consumption (OR, 2.11; 95% CI, 1.47-3.04) were the risk factors for rectosigmoid adenomas in men. Increasing age was the only risk factor for rectosigmoid adenomas in women (OR, 1.03; 95% CI, 1.01-1.06).
CONCLUSIONAge, hypertriglyceridemia and alcohol consumption are associated with rectosigmoid adenomas in men, and only age is significantly associated with rectosigmoid adenomas in women.

INTRODUCTIONThe purpose of this study was to explore whether diabetes mellitus (DM) correlates with the risk of kidney cancer in Taiwan.
MATERIALS AND METHODSWe designed a population-based case-control study from the Taiwan National Health Insurance Database, which consisted of 116 patients with newly diagnosed kidney cancer as cases and 464 subjects without kidney cancer as controls in 2000 to 2009. Both cases and controls were aged ≥20 years. Baseline comorbidities were compared between kidney cancer cases and controls.
RESULTSMultivariable analysis showed no association was detected between DM and kidney cancer (OR 1.06, 95% CI, 0.58 to 1.94). Hypertension (OR 2.05, 95% CI, 1.23 to 3.42), chronic kidney diseases (OR 2.57, 95% CI, 1.23 to 5.37), cystic kidney diseases (OR 18.6, 95% CI, 1.84 to 187.6) and kidney stones (OR 4.02, 95% CI, 2.43 to 6.66) were significant comorbidities associated with increased risk of kidney cancer. Use of alpha-glucosidase inhibitor was associated with increased risk of kidney cancer (OR 4.31, 95% CI, 1.07 to 17.3).
CONCLUSIONDM does not correlate with the risk of kidney cancer. Hypertension, chronic kidney diseases, cystic kidney diseases, kidney stones and use of alpha-glucosidase inhibitors are associated with kidney cancer.

INTRODUCTIONThe objective of this study was to explore the association between thrombocytopenia and its related factors.
MATERIALS AND METHODSThis was a hospital-based, cross-sectional study. We retrospectively analysed the medical records of all patients who received periodic health examinations at a medical centre located at Taichung in Taiwan between 2000 and 2004. In all, 5585 subjects were included for further analysis. A complete physical examination, laboratory survey and abdominal ultrasonography were performed on each subject. The t-test, chi-square test and multivariate logistic regression analysis were used.
RESULTSThe subjects consisted of 3123 men (55.9%) and 2462 women (44.1%). The mean age was 49.4 +/- 12.3 years (range, 20 to 87). The overall prevalence of thrombocytopenia was found to be 0.5%, higher in men than in women (0.6% vs 0.4%, P = 0.504). After controlling for the other covariates, multivariate logistic regression analysis exhibited that the factors significantly related to thrombocytopenia were increasing age (OR, 1.04; 95% CI, 1.004-1.08), anti-HCV positive (OR, 5.24; 95% CI, 2.08-13.20), liver cirrhosis (OR, 7.93; 95% CI, 2.28-27.62), and splenomegaly (OR, 18.86; 95% CI, 6.86-51.87).
CONCLUSIONIt is advisable to further check the hepatic status, if thrombocytopenia is noted.
