Objective: To evaluate the risk of Parkinson disease (PD) among patients with depression by using the Taiwan National Health Insurance Research Database (NHIRD)., Methods: We conducted a retrospective study of a matched cohort of 23,180 participants (4,634 patients with depression and 18,544 control patients) who were selected from the NHIRD. Patients were observed for a maximum of 10 years to determine the rates of new-onset PD, and Cox regression was used to identify the predictors of PD. We also examined the risk of PD after excluding patients who were diagnosed with PD within 2 or 5 years after their depression diagnosis. A logistic regression model was used to identify risk factors associated with PD onset in patients with depression., Results: During the 10-year follow-up period, 66 patients with depression (1.42%) and 97 control patients (0.52%) were diagnosed with PD. After adjusting for age and sex, patients with depression were 3.24 times more likely to develop PD (95% confidence interval 2.36-4.44, p < 0.001) compared with the control patients. After excluding patients who were diagnosed with PD within 2 or 5 years after their depression diagnosis, patients with depression had a higher hazard ratio for developing PD than the control patients. The odds ratios for age (1.09) and difficult-to-treat depression (2.18) showed that each is an independent risk factor for PD in patients with depression., Conclusion: The likelihood of developing PD is greater among patients with depression than patients without depression. Depression may be an independent risk factor for PD.

Objective: To examine the association between the risks of depression and vascular dementia (VaD) based on Taiwan's National Health Insurance Research Database.Methods: This retrospective longitudinal matched-cohort study used National Health Insurance Research Database data from 49,955 participants (9,991 with new onset depression, 39,964 controls). A Cox regression analysis was performed on the whole sample and the subgroup of patients with depression. We further excluded patients who developed VaD within 3 or 5 years after enrollment to evaluate depression as an independent risk factor for or a prodrome of VaD.Results: During the 10-year follow-up period, the incidence rate ratio of VaD between patients with depression and controls was 4.24 [95% confidence interval (CI) 2.90-6.21, P < 0.001]. After adjustment for covariates, the hazard ratio (HR) of VaD in patients with depression was 3.10 (95% CI 2.13-4.52, P < 0.001). In the whole sample, risk factors for VaD besides depression were aged ≥60 years (HR = 20.08), hypertension (HR = 1.70), diabetes (HR = 1.61), coronary artery disease (HR = 2.26), head injury (HR = 2.20), and cerebrovascular disease (HR = 3.02). In patients with depression, aged ≥60 years (HR = 32.16), coronary artery disease (HR = 2.82), head injury (HR = 2.06), and cerebrovascular disease (HR = 2.37) remained risk factors for VaD. After excluding those who developed VaD within 3 or 5 years, HRs remained high (3.28, 95% CI 2.03-5.31, P < 0.001; 2.12, 95% CI 1.05-4.25, P = 0.035, respectively).Conclusions: Our findings suggest that depression is an independent risk factor for subsequent VaD. Older age, cerebrovascular disease, head injury, and coronary artery disease might increase the risk of VaD among patients with depression. [ABSTRACT FROM AUTHOR]

The chronic autoimmune disease myasthenia gravis (MG) is characterized by fluctuating muscle weakness, which can lead to a large amount of stress in the patient. The current investigation plans to assess the risk of depressive disorders in MG patients. A retrospective cohort study of patients ageing 20 years and older and also newly diagnosed with MG between January 1, 2000, and December 31, 2008, was conducted from the National Health Insurance Research Database (NHIRD) in Taiwan. Observations of all 349 MG patients and 1,396 control individuals were made until a diagnosis of a depressive disorder by a psychiatrist, until death, or until December 31, 2013. A range of comorbidities were found, such as coronary artery disease, hypertension, diabetes mellitus, and dyslipidemia, with cerebrovascular disease being reported more frequently in MG patients in comparison with control subjects. After adjustment of patients' sex, age, urbanization, comorbidities, and monthly income, results indicated that MG individuals are 1.94 times more at risk (95% confidence interval [CI], 1.15–3.27, P = 0.014) of developing depressive disorders than are controls. This showed an increased risk in the development of depressive disorders in people with MG. Thus, depressive symptoms in MG patients should be regularly assessed. [ABSTRACT FROM AUTHOR]

Objectives: There are limited studies describing the association between ankylosing spondylitis (AS) and osteoporosis. We conducted a nationwide retrospective cohort study to investigate this epidemiologic evidence. Methods: Data were obtained from the Taiwan National Health Insurance Research Database (NHIRD). Of 10,290 participants, 2,058 patients with AS and 8,232 patients without AS were enrolled from the NHIRD between 2000 to 2013. Cumulative incidences of osteoporosis were compared between 2 groups. Cox regression model was used to estimate the hazard ratio (HR) of developing osteoporosis after controlling for demographic and other co-morbidities, and subgroup analyses were conducted to examine the risk factors for osteoporosis in AS patients. Results: The incidence rate ratio (IRR) of osteoporosis in AS patients was 2.17 times higher than that non-AS group (95% confidence interval [CI], 1.83–2.57). The adjusted HRs of osteoporosis for AS patients after controlling for demographic characteristics and comorbid medical disorders was 1.99 (95% CI 1.68–2.36). Among AS group, after adjustment for major comorbidities, old age (≥65 years, HR 4.32, 95% CI 3.01–6.18), female sex (HR 2.48, 95% CI 1.87–3.28), dyslipidemia (HR 1.44, 95% CI 1.01–2.06) were risk factors associated with osteoporosis. Conclusions: This cohort study demonstrated that patients with AS had a higher risk of developing osteoporosis, especially in those aged over 65, female sex and with dyslipidemia in this patient group.

Background: Some studies have suggested that depressive disorders may play a vital role in the incidence of hip fractures. However, nationwide data are lacking regarding the association between depressive disorders and hip fractures. Objective: We aimed to explore the association between depressive disorders and new-onset hip fractures. Methods: We conducted a retrospective study of 11,207 patients with depressive disorders and 11,207 control patients using Taiwan’s National Health Insurance Research Database. A Cox regression model was used to evaluate the risk of hip fractures in patients with depressive disorders. Results: The incidence rate ratio of hip fractures between patients with depressive disorders and controls was 1.6 (95% confidence interval [CI] = 1.29–1.99, P < .001). After adjustment for potential confounders in multivariate analysis using the Cox regression model, patients with depressive disorders were found to have 1.34 times higher risk of hip fractures than controls (95% CI = 1.08–1.66, P = .008). Furthermore, age (hazard ratio [HR] = 7.43, 95% CI = 4.94–11.19, P < .001), hypertension (HR = 1.63, 95% CI = 1.17–2.28, P = .004), diabetes mellitus (HR = 1.47, 95% CI = 1.08–1.99, P = .014), cerebrovascular disease (HR = 1.76, 95% CI = 1.31–2.35, P < .001), living in rural areas (HR = 1.88, 95% CI = 1.30–2.70, P = .001), and low monthly income (NT$0–NT$19,000: HR = 4.08, 95% CI = 1.79–9.29, P = .001 and NT$19,100–NT$42,000: HR = 4.09, 95% CI = 1.76–9.49, P = .001) were independent risk factors for new-onset hip fractures in patients with depressive disorders. Conclusion: Depressive disorders might increase the risk of new-onset hip fractures, particularly in older patients and patients with hypertension, diabetes mellitus, cerebrovascular disease, or low socioeconomic status.

Background:This study identified possible risk factors for newly diagnosed mood disorders, including depressive and bipolar disorders, in prostate cancer patients.Methods:From 2000 to 2006, two cohorts were evaluated on the occurrence of mood disorder diagnosis and treatment. For the first cohort, data of patients diagnosed with prostate cancer was obtained from the Taiwan National Health Insurance (NHI) Research Database. As the second cohort, a cancer-free comparison group was matched for age, comorbidities, geographic region, and socioeconomic status.Results:Final analyses involved 12,872 men with prostate cancer and 12,872 matched patients. Increased incidence of both depressive (IRR 1.52, 95% CI 1.30–1.79, P <0.001) and bipolar disorder (IRR 1.84, 95% CI 1.25–2.74, P = 0.001) was observed among patients diagnosed with prostate cancer. Multivariate matched regression models show that cerebrovascular disease (CVD) and radiotherapy treatment could be independent risk factors for developing subsequent depressive and bipolar disorders.Conclusion:We observed that the risk of developing newly diagnosed depressive and bipolar disorders is higher among Taiwanese prostate cancer patients. Clinicians should be aware of the possibility of increased depressive and bipolar disorders among prostate cancer patients in Taiwan. A prospective study is necessary to confirm these findings.

• The higher care burden caregivers experienced, the more severe depression they had. • Caregivers' own depression predicted rejection, rather than caregiving behaviors. • Subjective burden can predicted both caregivers' rejection and caregiving behaviors. • Objective care burden was not significantly associated with rejection and caregiving behaviors. • Reassurance seeking predicted increased, rather than reduced, caregiving behaviors. Taking care of depressed patients significantly impacts caregivers' lives, both objectively and subjectively. The effects of caregivers' burden on their responses to their patients has yet to be investigated. The aim of this study is to explore the relationships among caregivers' subjective and objective burden, depression, frequency of caregiving behaviors, and rejective attitude. A cross-sectional study was conducted among 134 caregivers of patients diagnosed with depressive disorders. We administered questionnaire to assess caregivers' demographics, care burden, reassurance seeking, depression, rejective attitude and caring behaviors. Both caregivers' objective and subjective burdens were associated with their depressive symptoms. Rejection towards patients was determined by the caregivers' level of depressive symptoms, subjective feeling of sadness, and anger, rather than by their objective burden. On the other hand, the frequency of caregiving behavior was determined by perceived reassurance seeking and anger, rather than by caregivers' depression or objective burden. These findings suggest that caregivers' subjective burden plays a more salient role in predicting their rejection and frequency of caregiving behaviors toward the patients than objective burden. The caregivers in this study could recognize their rejective attitude toward depressed patients but still had difficulty withdrawing their care when they were already in distress.
