Project description:Condyloma acuminata currently affects around 1% of sexually active adults, and its incidence is increasing. The coexistence of genital warts (GW) and certain cancers and an association between human papillomavirus (HPV) and various malignancies have been reported. Therefore, we conducted this large national study to analyze the risk of malignancies among men and women with GW in Taiwan.Between January 2000 and December 2013, approximately 3 million patients were reported to the National Health Insurance Research Database of Taiwan. Of these patients, 21,763 were diagnosed with GW. In the same time period, a total of 213,541 cancer cases were reported to the registry, of which 1002 were recorded among patients with GW. The age-specific incidence rates of GW and standardized incidence ratios (SIRs) of malignancies compared to the general population were calculated. Women acquired GW earlier than men, with a mean age at diagnosis of 32.63±12.78 years. The highest incidence rate for both genders peaked at 20-29 years. Of the 1002 patients with GW and malignancies, the SIR was 1.95 (95%CI 1.83-2.07). The most markedly increased risk was found for HPV-related cancers, with a SIR of 9.74 (95%CI 3.70-15.77). Significantly elevated risks were also noted for smoking-related cancers, anogenital cancers, cervix in situ, colon, rectum, lung, kidney, and prostate cancers. Most cancers developed within 10 years after the diagnosis of GW.Patients with GW have an increased risk of HPV-related cancers, especially anogenital malignancies in Taiwan. The elevated risk of other cancers highlights differences in exposure and risk factors among patients with GW compared to the general population. Cancer screening and HPV vaccination programs should be emphasized for at-risk patients.

Project description:ObjectivesTo estimate stroke risk in Taiwanese patients with gout.MethodsWe enrolled patients from the Taiwan National Health Insurance Database, with gout diagnosed from 2000 to 2008, and followed them up until December 2018. This cohort was propensity score-matched according to birth year, sex, the date of diagnosis of gout, comorbidities, and co-medications with individuals without gout (controls) (n = 310,820 in each group). Stroke was defined as the primary diagnosis at discharge after the index date. To evaluate ischemic and hemorrhagic stroke risks, we calculated their incidence, hazard ratio (HR), and two-year moving average incidence rate.ResultsThe incidence (95% CI) and HR of ischemic stroke were lower in the gout group than in the control group in the first 3 years (incidence: 4.74 [4.60-4.88] vs. 5.17 [5.03-5.32] per 1000 person-years; HR: 0.92 [0.88-0.96]), then became significantly higher than in the control group after 3 years (incidence: 4.10 [4.04-4.16] vs. 3.81 [3.75-3.87] per 1000 person-years; HR: 1.08 [1.05-1.10]). Similarly, the incidence (95% CI) and HR of hemorrhagic stroke was lower in the gout group than in the control group in the first 3 years (incidence: 1.51 [1.43-1.59] vs. 1.70 [1.62-1.79] per 1000 person-years; HR: 0.88 [0.82-0.92]), then became significantly higher than in controls after 3 years (incidence: 1.43 [1.39-1.46] vs. 1.26 [1.22-1.29] per 1000 person-years; HR: 1.14 [1.10-1.18]).ConclusionsIn Taiwan, patients with gout had higher risks of ischemic and hemorrhagic stroke after 3 years.

Project description:OBJECTIVE:Our population-based research aimed to clarify the association between chronic kidney disease (CKD) and mortality risk in patients with lung cancer. DESIGN:Retrospective cohort study SETTING: National health insurance research database in Taiwan PARTICIPANTS: All (n=1?37?077) Taiwanese residents who were diagnosed with lung cancer between 1997 and 2012 were identified. Eligible patients with baseline CKD (n=2269) were matched with controls (1:4, n=9076) without renal disease according to age, sex and the index day of lung cancer diagnosis. METHODS:The cumulative incidence of death was calculated by the Kaplan-Meier method, and the risk determinants were explored by the Cox proportional hazards model. RESULTS:Mortality occurred in 1866 (82.24%) and 7135 (78.61%) patients with and without CKD, respectively (P=0.0001). The cumulative incidences of mortality in patients with and without chronic renal disease were 72.8% vs 61.6% at 1?year, 82.0% vs 76.6% at 2 years and 88.9% vs 87.2% at 5 years, respectively. After adjusting for multiple confounding factors including age and comorbidities, Cox regression analysis revealed that CKD was associated with an increased risk of mortality (adjusted HR 1.38; 95% CI 1.29 to 1.47). Stratified analysis further showed that the association was consistent across patient subgroups. CONCLUSION:Comorbidity associated with CKD is a risk factor for mortality in patients with lung cancer.

Project description:Osteoarthritis (OA) and dementia are prevalent causes of disability in geriatric patients. To date, information on the temporal correlation between these progressive diseases and the risk of dementia in patients with OA is limited. This retrospective population-based 4-year cohort study investigated the risk of dementia in patients with OA. We performed a case-control matched analysis by using the Taiwan Longitudinal Health Insurance Database 2005. Patients were selected on the basis of International Classification of Diseases, Ninth Revision, Clinical Modification codes for OA between January 1, 2004 and December 31, 2007. The prevalence and the adjusted hazard ratio (HR) of dementia in patients with and without OA were estimated. The OA cohort comprised 35,149 patients and the non-OA cohort (comparison cohort) comprised 70,298 patients (1:2). The incidence of dementia was 21.7 per 10,000 person-years in the OA cohort and 14.7 per 10,000 person-years in the non-OA cohort. The HR for dementia during the follow-up period was 1.33 (95% confidence interval [CI], 1.17-1.50, P < 0.001) for patients with OA. The adjusted HR for dementia was 1.25 (95% CI, 1.10-1.43, P < 0.001) for patients with OA. The results of this study indicated that OA is an independent risk factor for dementia.

Project description:ObjectiveThe pathogenesis of keloid is largely unknown. Because keloid and atopic dermatitis have overlapping pathophysiological mechanisms, we aimed to evaluate keloid risk in patients with atopic dermatitis.Study designPopulation-based retrospective cohort study.SettingThe Taiwan National Health Insurance Research Database was used to analyse data for people who had been diagnosed with atopic dermatitis.ParticipantsWe identified 8371 patients with newly diagnosed atopic dermatitis during 1996-2010. An additional 33 484 controls without atopic dermatitis were randomly identified and frequency matched at a one-to-four ratio.Primary and secondary outcome measureThe association between atopic dermatitis and keloid risk was estimated using Cox proportional hazard regression models.ResultsAfter adjustment for covariates, the atopic dermatitis patients have a 3.19-fold greater risk of developing keloid compared with the non-atopic dermatitis group (3.19vs1.07 per 1000 person-years, respectively). During the study period, 163 patients with atopic dermatitis and 532 patients without atopic dermatitis developed keloid. Notably, keloid risk increased with severity of atopic dermatitis, particularly in patients with moderate to severe atopic dermatitis.ConclusionsOur results indicate that patients with atopic dermatitis had a higher than normal risk of developing keloid and suggest that atopic dermatitis may be an independent risk factor for keloid.

Project description:BACKGROUND: This study examined the risk of cancer in patients with Hashimoto's thyroiditis (HT). METHODS: The Taiwanese National Health Insurance Research Database (NHIRD) was used to identify 1521 newly diagnosed HT patients from 1998-2010, and 6084 frequency-matched non-HT patients. The risk of developing cancer for HT patients was measured using the Cox proportional hazard model. RESULTS: The incidence of developing cancer in the HT cohort was 5.07 per 1000 person-years, which was 1.68-fold higher than that in the comparison cohort (P<0.001). Compared with patients aged 20-34 years, patients in older age groups had a higher risk of developing cancer (35-55 years: hazard ratio (HR)=5.96; >55 years: HR=9.66). After adjusting for sex, age, and comorbidities, the HT cohort had HRs of 4.76 and 11.8 for developing colorectal cancer and thyroid cancer, respectively, compared with non-HT cohort. Furthermore, the HT cohort to non-HT cohort incidence rate ratio (IRR) of thyroid cancer was higher in the first 3 years (48.4, 95% confidence interval (CI)=35.0-66.3), with an adjusted HR of 49.4 (95% CI=6.39-382.4). CONCLUSION: Hashimoto's thyroiditis patients have a higher risk of thyroid cancer and colorectal cancer. The thyroid cancer prevention effort should start soon after HT is diagnosed, while being cautious of colorectal cancer increases with time.

Project description:The relationship between congenital heart disease (CHD) and malignancies has not been determined. This study aimed to explore the association of CHD with malignancies and examine the risk factors for the development of cancer after a diagnosis of CHD.This nationwide, population-based cohort study on cancer risk evaluated 31,961 patients with newly diagnosed CHD using the Taiwan National Health Insurance Research Database (NHIRD) between 1998 and 2006. The standardized incidence ratios (SIRs) for all and specific cancer types were analyzed, while the Cox proportional hazard model was used to evaluate risk factors of cancer occurrence.Among patients with newly diagnosed CHD regardless of ages, 187 (0.6%) subsequently developed cancers after a diagnosis of CHD. Patients with CHD had increased risk of cancer (SIR, 1.45; 95% CI, 1.25-1.67), as well as significantly elevated risks of hematologic (SIR, 4.04; 95% CI, 2.76-5.70), central nervous system (CNS) (SIR, 3.51; 95% CI, 1.92-5.89), and head and neck (SIR, 1.81; 95% CI, 1.03-2.94) malignancies. Age (HR, 1.06; 95% CI, 1.05-1.06) and co-morbid chronic liver disease (HR, 1.91; 95% CI, 1.27-2.87) were independent risk factors for cancer occurrence among CHD patients.Patients with CHD have significantly increased cancer risk, particularly hematologic, CNS, and head and neck malignancies. Physicians who care for patients with CHD should be aware of their predisposition to malignancy after the diagnosis of CHD. Further studies are warranted to clarify the association between CHD and malignancies.

Project description:BackgroundData on the use of oral anticoagulation (OAC) and antiplatelet therapy and the risk of bleeding and stroke amongst Asian patients with atrial fibrillation (AF) are limited. We investigated the risks of bleeding and stroke with use of oral anticoagulation (OAC) and antiplatelet therapy as mono- or combination therapy, in patients with AF from a Chinese nationwide cohort study.MethodsWe studied a cohort of 10384 patients (57.2% men, age 67.8 ± 13.2 yrs) between 1999 and 2010 from the National Health Insurance Research Database in Taiwan. Records of prescriptions were obtained during follow-up. The main outcome was a recurrent stroke during the follow-up period. Time-dependent Cox proportional hazards models were used for this analysis.ResultsWe documented 1009 events for bleeding, as well as 224 hemorrhagic stroke and 1642 ischemic stroke events during a median 3.2 (interquartile range, 1.05-6.54) years' follow-up. Compared with warfarin users, patients with antiplatelet therapy had a lower risk of bleeding (adjusted relative risk [RR], 0.59, 95% confidence interval [CI], 0.49-0.71, p<0.001) whilst combination therapy had a non-statistically significant higher bleeding risk (RR, 1.33, 95%, 0.91-1.94, p = 0.20). Patients on antiplatelet monotherapy had a similar risk for ischemic stroke compared with OAC (RR 1.05, 95% CI, 0.89-1.25, p = 0.50), whilst those on combination therapy had a significantly higher risk (RR 1.90, 95% CI, 1.34-2.70, p<0.001).ConclusionIn a national representative cohort, antiplatelet therapy had no significant difference in ischemic stroke risk to warfarin. For bleeding, aspirin had a lower risk compared to warfarin. This may reflect poor anticoagulation control, highlighting important missed opportunities for improved stroke prevention, especially in countries where anticoagulation management is suboptimal.

Project description:BackgroundApproximately 25-30% of individuals worldwide are infected with Toxoplasma gondii (T. gondii), which is difficult to detect in its latent state. We aimed to evaluate the association between toxoplasmosis, the risk of dementia, and the effects of antibiotics in Taiwan.MethodsThis nationwide, population-based, retrospective cohort study was conducted using the Longitudinal Health Insurance Database containing the records of 2 million individuals retrieved from Taiwan's National Health Insurance Research Database. Fine-Gray competing risk analysis was used to determine the risk for the development of dementia in the toxoplasmosis cohort relative to the non-toxoplasmosis cohort. A sensitivity analysis was also conducted. The effects of antibiotics (sulfadiazine or clindamycin) on the risk of dementia were also analyzed.ResultsWe enrolled a total of 800 subjects, and identified 200 patients with toxoplasmosis and 600 sex- and age-matched controls without toxoplasmosis infection in a ratio of 1:3, selected between 2000 and 2015. The crude hazard ratio (HR) of the risk of developing dementia was 2.570 [95% confidence interval (CI) = 1.511-4.347, P < 0.001]. After adjusting for sex, age, monthly insurance premiums, urbanization level, geographical region, and comorbidities, the adjusted HR was 2.878 (95% CI = 1.709-4.968, P < 0.001). Sensitivity analysis revealed that toxoplasmosis was associated with the risk of dementia even after excluding diagnosis in the first year and the first 5 years. The usage of sulfadiazine or clindamycin in the treatment of toxoplasmosis was associated with a decreased risk of dementia.ConclusionsThis finding supports the evidence that toxoplasmosis is associated with dementia and that antibiotic treatment against toxoplasmosis is associated with a reduced risk of dementia. Further studies are necessary to explore the underlying mechanisms of these associations.

Project description:PurposeAbdominal aortic aneurysm (AAA) is a critical disease. Most studies of AAA consider reoperation rate, complications, or mortality, but do not consider a patient's mental state. However, there is a possibility of interaction between AAA and depression in disease development and prognosis. We investigated the incidence and risk ratio of depression in patients with AAA using nationwide data.MethodsWe selected subjects from National Health Insurance System database who were diagnosed with AAA between 2009 and 2015 and survived at least 1 year after diagnosis or AAA surgery (n = 10,373). We determined the control group using propensity score matching by age and sex. The control group had about 3 times the number of subjects as the AAA cohort (n = 31,119).ResultsThe incidence of depression was 1.4 times higher in the AAA group than the control group. We further analyzed the incidence of depression in the AAA group according to treatment modalities (nonsurgical vs. surgical or nonsurgical vs. open surgical aneurysm repair vs. endovascular aneurysm repair) but found no significant difference among them. The incidence of depression was significantly higher in patients aged <65 years than in patients aged ≥65 years (hazard ratio, 1.539 vs. 1.270; P < 0.001).ConclusionThe incidence of depression was higher in the AAA group, with an especially high risk for depression in patients aged <65 years. The psychiatric status of patients with AAA should be carefully monitored for clinicians to intervene when appropriate.
