The impact of urbanization on cataract incidence is still inconclusive. This study aimed to examine the association of urbanization and sunlight exposure with cataract incidence using a nationwide population-based database in Taiwan. The researchers used data retrieved from the Taiwan Longitudinal Health Insurance Database from 2001 to 2010 (LHID2010). The LHID2010 consists of medical claims data for reimbursement for 1 million individuals randomly selected from all enrollees (N = 23.25 million) in the Taiwan National Health Insurance (NHI) program in 2010. For adults aged over 40, we identified a total of 3080 people diagnosed with senile cataracts (ICD-9:360) and 393,241 people without senile cataracts in the LHID2010. In addition, sunlight exposure data between 2001 and 2011 were obtained from 28 meteorological stations of the Taiwan Central Weather Bureau. Logistic regression was performed to test the hypothesis. When controlled for the confounding factors, such as demographic factors, comorbidities, and sunlight exposure, the logistic regression results showed that those living in highly urbanized areas are more likely to suffer from senile cataracts (p < 0.001).

The Impact

Background Cluster headache (CH) is well known to show a seasonal predilection; however, the impact of temperature and other meteorological factors on cluster periods (or bouts) has not been established. Methods This nationwide survey included 758 patients with episodic CH retrieved from the Taiwan National Health Insurance Research Database from 2005 to 2009. Corresponding meteorological recordings were obtained from the Central Weather Bureau. A case-crossover study design was used to investigate the association between cluster periods and meteorological factors. Results A total of 2452 episodes of cluster periods were recorded. The cluster periods were most frequent in the autumn and least frequent in the winter. Seasonal changes from winter to spring and from autumn to winter also increased the frequency of cluster periods. The risk of cluster periods increased when there was a higher mean temperature on event days (odds ratio (OR), 1.014, 95% confidence interval (CI), 1.005–1.023, p = 0.003) or within seven to 56 days. Either an increase or a decrease in temperature (0.05℃/day) following a warm period (mean temperature ≥26℃) was associated with the onset of cluster periods. In contrast, a greater increase in temperature (0.15℃/day) following a cold period (mean temperature < 21℃) was needed to evoke cluster periods. No such associations were found following moderate periods (21℃ ≤mean temperature <26℃). Discussion Our study shows that temperature is associated with precipitating or priming cluster periods. The influence depends on the temperature of the preceding periods.

ABSTRACTBackground:The purpose of this paper was to examine whether glaucoma could be a non-memory manifestation of Alzheimer's disease in older people.Methods:We conducted a population-based, retrospective, case-control study to analyze the database of the Taiwan National Health Insurance Program. There were 1,351 subjects ≥65 years old with newly diagnosed Alzheimer's disease as the cases, and 5,329 subjects without any type of dementias as the controls during 2000–2011. The odds ratio (OR) and 95% confidence interval (CI) for the risk of Alzheimer's disease associated with glaucoma was estimated by the multivariable unconditional logistic regression model.Results:After controlling for confounders, the multivariable logistic regression model demonstrated that the adjusted OR of Alzheimer's disease was 1.50 in subjects with glaucoma (95% CI 1.19, 1.89), compared to subjects without glaucoma.Conclusions:Older people with glaucoma are associated with 1.5-fold increased odds of Alzheimer's disease in Taiwan. Glaucoma may be a non-memory manifestation of Alzheimer's disease in older people. Further research is needed to confirm this issue.

Abstract Background Childhood is an important public health issue. Although both thyroid hormone and menarche are known to play a role in body metabolism and energy expenditure, no population-based study has been conducted to investigate the impact of TSH on adipogenesis among population-based girls around puberty. Methods A multi-stage cluster sampling method was used to select one junior middle school from each of 4 study areas: Minhang District in Shanghai, Haimen City in Jiangsu Province, Yuhuan City and Deqing County in Zhejiang Province. A total of 474 girls aged 11 to 14 years from 4 schools were enrolled. Information on demographic factors and puberty stage were collected, and anthropometric measurements and thyroid hormones were determined. Multivariate logistic regression models were used to assess the associations of Thyroid stimulating hormone (TSH) with the risk of obesity measured by body mess index (BMI) and waist circumference (WC). Results Of the 474 girls, the prevalences of BMI-based general obesity and WC-based abdominal obesity were 19.8% (94/474) and 21.7% (103/474), respectively. Compared with normal weight girls, the mean serum TSH concentration was significantly higher in BMI-based general overweight or obese girls (P = 0.037), but not in WC-based central overweight or obese girls (P = 0.173). In the multiple logistic regression models, for girls with highest tertile of serum TSH concentration relative to those in the lowest tertile, the odds ratios were 2.58 (95% CI 1.32 to 5.04) and 2.50 (95% CI 1.30 to 4.81) for overweight or obesity based on BMI and WC after adjustment for puberty stage and other covariates. Conclusions Serum TSH concentration was positively associated with both general and abdominal obesity in school-age girls and the association was independent of puberty.

Background: We hypothesize that autoantibodies are induced after the blood-brain barrier is damaged by stroke and the risk of bullous pemphigoid (BP) is increased after stroke. We assess the risk of BP after first-ever stroke in a nationwide population-based cohort of first-ever stroke patients. Methods: We extracted data from the Longitudinal Health Insurance Database 2005 and identified patients with first-ever stroke as well as control patients matched for age, gender, and year of enrollment. The risk of BP in first-ever stroke patients in comparison with that in control patients was analyzed using Cox regression. Results: Of 12,607 patients with first-ever stroke, 38 (0.3%) patients developed BP in a median of 3.5 years. In the control patients, 8 persons (0.06%) had BP in a median of 3.7 years. The crude hazard ratio (HR) of BP in first-ever stroke patients was 4.83 (95% CI 2.25-10.34, p < 0.001) compared to the control group. The adjusted HR was 4.20 (95% CI 1.94-9.08, p < 0.001) after adjustments for age, gender, hypertension, diabetes, dementia, epilepsy, Parkinson disease, furosemide, and neuroleptics for stroke patients. Conclusions: The risk of BP is increased in first-ever stroke patients in a nationwide population-based cohort and this association is independent of well-known confounders of BP.

Abstract Background Proteinuria has been identified as a sign of systemic endothelial dysfunction and chronic inflammation, and associated with the development of several systemic inflammatory diseases. However, the impact of proteinuria and its severity on the incidence of inflammatory bowel disease (IBD) has not been studied yet. The aim of this study was to determine the association between proteinuria measured by urine dipstick test and the development of IBD. Methods We conducted a nationwide population-based cohort study using claims data from the National Health Insurance (NHI) database, a mandatory health insurance programme covering about 97% of the Korean population. A total of 9,917,400 people aged 20 years or older who had undergone a national health examination conducted by NHI in 2009 were followed until 2017. The study population was classified into four groups, negative, trace, 1+, and ≥2+, depending on the degree of proteinuria measured by urine dipstick test. The primary endpoint was the newly diagnosed IBD, Crohn’s disease (CD) or ulcerative colitis (UC) during the follow-up period, which was detected by both ICD-10 (K50 and K51) and the rare intractable disease registration programme codes which provide co-payment reduction of up to 90% in South Korea. Results The incidence of CD significantly increased according to the degree of proteinuria (adjusted hazard ratio [aHR] with 95% confidence interval [CI], 1.01(0.703–1.451), 1.515(1.058–2.162), and 2.053(1.301–3.24) in trace, 1+, and ≥2+ dipstick groups, respectively) as compared with the dipstick-negative group. However, there was no significant difference in the incidence of UC among the degrees of proteinuria (aHR with 95% CI, 1.12(0.949–1.323), 0.947(0.764–1.174), 1.009(0.741–1.373 in trace, 1+, and ≥2+ dipstick groups, respectively). In subgroup analysis, dipstick-positive proteinuria independently increased the incidence of CD regardless of subgroups. However, in the development of UC, dipstick-positive proteinuria increased the risk of UC in those with diabetes mellitus (DM), but not in those without DM (aHR, 1.527 vs. 0.846; interaction p-value 0.004). Conclusion Proteinuria, measured by dipstick test, may be associated with the development of CD.
