In order to determine whether Taiwanese vegetarian diets reduce the risks of depression, we analyzed data from the Tzu Chi Vegetarian Study (TCVS), which is a prospective cohort study following 12,062 participants from the Buddhist Tzu Chi Foundation of Taiwan since 2005. The cohort was prospectively followed by linking to the National Health Institute Research Database (NHIRD) of Taiwan and hazard ratios of depression between vegetarian and non-vegetarian groups were calculated by Cox proportional hazards regression. We assessed dietary intake using a detailed food frequency questionnaire (FFQ). Incident depression was ascertained through linkage to NHIRD which had claim records with the International Classification of Diseases, and a total of 3,571 vegetarians and 7,006 non-vegetarians were included in this analysis. Compared with non-vegetarians, the vegetarian group had a lower incidence of depressive disorders (2.37 vs. 3.21 per 10,000 person-years; adjusted hazard ratio (aHR): 0.70; 95% confidence interval (95% CI): 0.52–0.93). Thus, Taiwanese vegetarians had a lower risk of developing subsequent depressive disorders compared with non-vegetarians. This indicated that diet may be an important measure for the prevention of depression. However, to generalize to the global population requires further study.

Abstract Background Hypothyroidism has a detrimental effect on the immune system, which may predispose patients to infection. However, evidence about the risk of developing either community- or hospital-acquired pneumonia in patients with hypothyroidism is scarce. Objective To evaluate the association between hypothyroidism and the risk of developing pneumonia. Methods This was a retrospective population-based cohort study from Taiwan’s National Health Insurance Research Database. After 1:1 propensity score matching, 9749 patients (age ≥20 years) newly diagnosed with hypothyroidism between 2001 and 2014 and 9749 patients without hypothyroidism or other thyroid diseases were included in the hypothyroidism and non-hypothyroidism cohorts, respectively, and followed up until 2015. The development of pneumonia was defined as the primary outcome. Cox proportional hazards regression models were used to calculate the hazard ratios (HRs) of developing pneumonia between hypothyroidism and non-hypothyroidism cohorts after adjusting for age, sex and baseline comorbidities. To evaluate whether thyroxine replacement therapy (TRT) modified the risk for pneumonia, we divided patients with hypothyroidism into subgroups: patients who received TRT and those who did not. Results Hypothyroidism was associated with a higher risk of pneumonia [adjusted HR (aHR) 1.38, 95% confidence interval (CI) 1.29–1.49, P < 0.001]. Patients with hypothyroidism who received TRT had a lower risk of pneumonia than patients who did not (aHR 0.85, 95% CI 0.76–0.93, P = 0.001). Similar results were obtained in the age- and sex-stratified analyses. Conclusions Clinically diagnosed hypothyroidism was independently associated with the risk of pneumonia. In patients with hypothyroidism, TRT was associated with a lower risk of pneumonia.

Background:Chlamydia pneumoniae (CPn) is a common community-acquired pneumonia. In the literature, CPn infection is demonstrated to exhibit an association with Alzheimer dementia (AD). We executed the present nationwide, population-based research with the goal of probing the association of CPn infection and antibiotic therapy with AD risk.Methods: We conducted a cohort study using a database extracted from Taiwan's National Health Insurance Research Database (NHIRD). All medical conditions for each enrolled individuals were categorized using the International Classification of Diseases, ninth Revision classifications. Hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between CPn pneumonia-associated hospitalizations and AD were estimated using Fine and Gray's survival analysis and adjusted for comorbidities. The effects of the antibiotics on the HRs for AD in the patients with CPn pneumonia-associated hospitalization were also analyzed.Results: Our analyses included 6,628 individuals, including 1,657 CPn-infected patients, as well as 4,971 controls matched by age, index date, and sex (1:3). In this study, patients hospitalized for CPn pneumonia exhibited a significantly higher AD risk (adjusted HR = 1.599, 95% CI = 1.284–1.971, p < 0.001). We also noted an association of macrolide use (≥15 days) and fluoroquinolone use (≥15 days) with decreased AD risk.Conclusions: We determined CPn pneumonia to be associated with a relatively high AD risk. The result in this study confirmed the findings from previous literatures, by using a large, nationwide, population-based database. Appropriate macrolide and fluoroquinolone treatment may attenuate this risk.

Abstract We sought to examine the prospective associations of specific fruit consumption, in particular flavonoid-rich fruit (FRF) consumption, with the risk of stroke and subtypes of stroke in a Japanese population. A study followed a total of 39,843 men and 47,334 women aged 44-76 years, and free of cardiovascular disease, diabetes, and cancer at baseline since 1995 and 1998 to the end of 2009 and 2012, respectively. Data on total and specific FRF consumption for each participant were obtained using a self-administrated food frequency questionnaire. The hazard ratios (HRs) of stroke in relation to total and specific FRF consumption were estimated through Cox proportional hazards regression models. During a median follow-up of 13.1 years, 4092 incident stroke cases (2557 cerebral infarctions and 1516 hemorrhagic strokes) were documented. After adjustment for age, body mass index, study area, lifestyles, dietary factors, and other risk factors, it was found that total FRF consumption was associated with a significantly lower risk of stroke in women (HR= 0.70; 95% CI, 0.58-0.84), while the association in men was not significant (HR= 0.93; 95% CI, 0.79-1.09). As for specific FRFs, consumptions of citrus fruits, strawberries, and grapes were found associated with a lower stroke risk in women. Higher consumptions of FRFs, in particular citrus fruits, strawberries, and grapes, were associated with a lower risk of developing stroke in Japanese women.

Subarachnoid hemorrhage (SAH) is a critical illness that may result in patient mortality or morbidity. In this study, we investigated the outcomes of patients treated in medical center and nonmedical center hospitals and the relationship between such outcomes and hospital and surgeon volume. Patient data were abstracted from the National Health Insurance Research Database of Taiwan in the Longitudinal Health Insurance Database 2000, which contains all claims data of 1 million beneficiaries randomly selected in 2000. The International Classification of Diseases, Ninth Revision, subarachnoid hemorrhage (430) was used for the inclusion criteria. We identified 355 patients between 11 and 87 years of age who had subarachnoid hemorrhage. Among them, 32.4% (115/355) were men. The median Charlson comorbidity index (CCI) score was 1.3 (SD ± 0.6). Unadjusted logistic regression analysis demonstrated that low mortality was associated with high hospital volume (OR = 3.21; 95% CI: 1.18–8.77). In this study, we found no statistical significances of mortality, LOS, and total charges between medical centers and nonmedical center hospitals. Patient mortality was associated with hospital volume. Nonmedical center hospitals could achieve resource use and outcomes similar to those of medical centers with sufficient volume.

Aims:The risk factors for trying a cigarette are well known, however we were interested in the factors that determine which youths become addicted to nicotine once they have tried it.Method:To investigate this we followed a cohort of 1246 students (mean baseline age of 12.2 years) over 4 years. Subjects underwent 11 interviews during which we assessed 45 risk factors, measured diminished autonomy over tobacco with the Hooked On Nicotine Checklist, and evaluated tobacco dependence using the International Classification of Diseases-10th revision. Cox proportional hazards models were used.Results:Among 217 youths who had inhaled from a cigarette, the loss of autonomy over tobacco was predicted by feeling relaxed the first time inhaling from a cigarette (adJusted Hazard Ratio (HR)=3.26; 95% CI, 1.95-5.46; P< .001) and depressed mood (HR=1.29; 1.09-1.54; P=.004). Tobacco dependence was predicted by feeling relaxed (HR=2.43; 1.27-4.65; P=.007), familiarity with Joe Camel (HR=2.19; 1.11-4.32; P=.02), novelty seeking (HR=1.56; 1.06-2.29; P=.02), and depressed mood (HR=1.17; 1.04-1.30; P=.007).Conclusion:Once exposure to nicotine had occurred, remarkably few risk factors for smoking consistently contributed to individual differences in susceptibility to the development of dependence. An experience of relaxation in response to the first dose of nicotine was the strongest predictor of both dependence and lost autonomy. This association was not explained by trait anxiety or many other psychosocial factors. These results are discussed in relation to the theory that addiction is initiated by the first dose of nicotine.

Context: Diabetes is a risk factor for dementia, but the effects of diabetic severity on dementia are unclear. Objective: The purpose of this study was to investigate the association between the severity and progress of diabetes and the risk of dementia. Design and Setting: We conducted a 12-year population-based cohort study of new-onset diabetic patients from the Taiwan National Health Insurance Research Database. The diabetic severity was evaluated by the adapted Diabetes Complications Severity Index (aDCSI) from the prediabetic period to the end of follow-up. Cox proportional hazard regressions were used to calculate the hazard ratios (HRs) of the scores and change in the aDCSI. Participants: Participants were 431,178 new-onset diabetic patients who were older than 50 years and had to receive antidiabetic medications. Main Outcome: Dementia cases were identified by International Classification of Diseases, ninth revision, code (International Classification of Diseases, ninth revision, codes 290.0, 290.1, 290.2, 290.3, 290.4, 294.1, 331.0), and the date of the initial dementia diagnosis was used as the index date. Results: The scores and change in the aDCSI were associated with the risk of dementia when adjusting for patient factors, comorbidity, antidiabetic drugs, and drug adherence. At the end of the follow-up, the risks for dementia were 1.04, 1.40, 1.54, and 1.70 (P &lt; .001 for trend) in patients with an aDCSI score of 1, 2, 3, and greater than 3, respectively. Compared with the mildly progressive patients, the adjusted HRs increased as the aDCSI increased (2 y HRs: 1.30, 1.53, and 1.97; final HRs: 2.38, 6.95, and 24.0 with the change in the aDCSI score per year: 0.51–1.00, 1.01–2.00, and &gt; 2.00 vs &lt; 0.50 with P &lt; .001 for trend). Conclusions: The diabetic severity and progression reflected the risk of dementia, and the early change in the aDCSI could predict the risk of dementia in new-onset diabetic patients.

Aim: Use the National Health Insurance Research Database of Taiwan to determine whether patients with posttraumatic epilepsy (PTE) have an increased risk of mortality. Methods: Patients ≥20 years old ever admitted because of head injury (per International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes 850–854 and 959.01) during 2000–2012 were enrolled into a traumatic brain injury (TBI) cohort. The TBI cohort was divided into with PTE (ICD-9-CM code 345) and posttraumatic nonepilepsy (PTN) cohorts. We compared the PTE and PTN cohorts in terms of age, sex, and comorbidities. We calculated adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) of all-cause mortality risk in these cohorts. Results: Patients with PTE had a higher incidence rate (IR) of mortality than did patients with TBI alone (IR per 1000 person-years: 71.8 vs. 27.6), with an aHR 2.31 (95% CI = 1.96–2.73). Patients with PTE aged 20–49, 50–64, and ≥65 years had, respectively, 2.78, 4.14, and 2.48 times the mortality risk of the PTN cohort. Patients with any comorbidity and PTE had 2.71 times the mortality risk as patients in the PTN cohort. Furthermore, patients with PTE had 28.2 increased hospital days and 7.85 times as frequent medical visits per year compared with the PTN cohort. Conclusion: Taiwanese patients with PTE had approximately 2 times the mortality risk and an increased medical burden compared to patients with TBI only. Our findings provide crucial information for clinicians and the government to improve TBI outcomes.

ObjectiveTo estimate morbidity in Denmark in all patients with GH deficiency (GHD).DesignMorbidity was analyzed in 1794 GHD patients and 8014 controls matched on age and gender. All records in the GHD patients were studied and additional morbidity noted. Diagnoses and dates of admissions were identified in the National Patient Registry. Lag time until first admission was used as a measure of morbidity. Patients were divided into childhood onset (CO) and adult onset (AO), discriminated by an age cut-off of 18 years at onset of GHD.MethodSex- and cause-specific hazard ratios (HRs) in CO and AO GHD compared with controls.ResultsTotal morbidity was significantly increased in the GHD patients. HR for CO males: 3.1 (95% confidence interval (CI): 2.7–3.7), CO females: 3.2 (95% CI: 2.6–3.9), AO males: 2.9 (95% CI: 2.6–3.2), and AO females: 3.2 (95% CI: 2.8–3.6). In 18 out of 20 chapters from the International Classification of Diseases-10, a significantly increased morbidity was identified for at least one of the four subgroups of patients. Morbidity was significantly increased in all the four subgroups due to infectious, endocrine, pulmonary, urogenital, and neurological diseases; cancer; diseases of the eye, ear, and circulatory diseases; and traumas. Fractures were significantly increased in AO females, not in males.ConclusionsMorbidity was significantly increased in the GHD patients. The increased morbidity was due to a variety of disorders, some of which can readily be explained by GHD and other pituitary deficiencies, while others cannot be easily explained.

Objective.To analyze the trend of prevalence and incidence rates for psoriatic arthritis (PsA) and psoriasis in Taiwan, and to determine the changes in medication patterns.Methods.Data were collected from the Taiwan National Health Insurance Research Database, which covered at least 95% of the population from 2000 to 2013. International Classification of Diseases, 9th edition (ICD-9) was used to identify PsA (ICD-9 696.0) and other psoriasis (ICD-9 696.1). Medications were identified by Anatomical Therapeutic Chemical Classification code. We calculated the annual age standardized prevalence and incidence rate of PsA and psoriasis in individuals aged ≥ 16 years from 2000 to 2013, and used the Poisson regression to test the trends by Wald chi-square statistic.Results.The prevalence (per 100,000 population) of psoriatic diseases between 2000 and 2013 increased from 11.12 to 37.75 for PsA, and from 179.2 to 281.5 for psoriasis. The incidence (per 100,000 person-yrs) increased from 3.64 to 6.91 in PsA, while there was no significant change in psoriasis. Prevalence and incidence in PsA were more rapidly increased than in psoriasis. Sex ratio (men to women) of PsA decreased from 2.0 to 1.5 in 2000 and 2013, respectively. There was an increase in the use of disease-modifying antirheumatic drugs (DMARD), especially biologics, which is significantly different from topical therapies.Conclusion.The prevalence and incidence rates of psoriatic disease, especially PsA, were increasing in Taiwan. The medication pattern showed an increase in DMARD and biologics, while use of topical therapies decreased.

Background: Vaccines may elicit long-term boosting of innate immune responses that can help protect against COVID-19. We evaluated the association between recombinant adjuvanted zoster vaccine (RZV) and COVID-19 outcomes at Kaiser Permanente Southern California. Methods: In a cohort design, adults aged ≥50 years who received ≥1 RZV dose prior to 3/1/2020 were matched 1:2 to unvaccinated individuals and followed until 12/31/2020. Adjusted hazard ratios (aHR) and 95% confidence intervals (CIs) for COVID-19 outcomes were estimated using Cox proportional hazards regression. In a test-negative design, cases had a positive SARS-CoV-2 test and controls had only negative tests, from 3/1/2020-12/31/2020. Adjusted odds ratios (aOR) and 95% CIs for prior receipt of RZV were estimated using logistic regression. Results: In the cohort design, 149,244 RZV recipients were matched to 298,488 unvaccinated individuals. The aHRs (95% CI) for COVID-19 diagnosis and hospitalization were 0.84 (0.81-0.87) and 0.68 (0.64-0.74), respectively. In the test-negative design, 8.4% of 75,726 test-positive cases and 13.1% of 340,898 test-negative controls had received ≥1 RZV dose. The aOR (95% CI) was 0.84 (0.81-0.86). Conclusion: RZV vaccination was associated with a 16% lower risk of COVID-19 diagnosis and 32% lower risk of hospitalization, suggesting RZV elicits heterologous protection, possibly through trained immunity.
