BackgroundEpidemiological evidence suggests a cardioprotective role of α‐linolenic acid (ALA), a plant‐derived ω‐3 fatty acid. It is unclear whether ALA is beneficial in a background of high marine ω‐3 fatty acids (long‐chain n‐3 polyunsaturated fatty acids) intake. In persons at high cardiovascular risk from Spain, a country in which fish consumption is customarily high, we investigated whether meeting the International Society for the Study of Fatty Acids and Lipids recommendation for dietary ALA (0.7% of total energy) at baseline was related to all‐cause and cardiovascular disease mortality. We also examined the effect of meeting the society's recommendation for long‐chain n‐3 polyunsaturated fatty acids (≥500 mg/day).Methods and ResultsWe longitudinally evaluated 7202 participants in the PREvención con DIeta MEDiterránea (PREDIMED) trial. Multivariable‐adjusted Cox regression models were fitted to estimate hazard ratios. ALA intake correlated to walnut consumption (r=0.94). During a 5.9‐y follow‐up, 431 deaths occurred (104 cardiovascular disease, 55 coronary heart disease, 32 sudden cardiac death, 25 stroke). The hazard ratios for meeting ALA recommendation (n=1615, 22.4%) were 0.72 (95% CI 0.56–0.92) for all‐cause mortality and 0.95 (95% CI 0.58–1.57) for fatal cardiovascular disease. The hazard ratios for meeting the recommendation for long‐chain n‐3 polyunsaturated fatty acids (n=5452, 75.7%) were 0.84 (95% CI 0.67–1.05) for all‐cause mortality, 0.61 (95% CI 0.39–0.96) for fatal cardiovascular disease, 0.54 (95% CI 0.29–0.99) for fatal coronary heart disease, and 0.49 (95% CI 0.22–1.01) for sudden cardiac death. The highest reduction in all‐cause mortality occurred in participants meeting both recommendations (hazard ratio 0.63 [95% CI 0.45–0.87]).ConclusionsIn participants without prior cardiovascular disease and high fish consumption, dietary ALA, supplied mainly by walnuts and olive oil, relates inversely to all‐cause mortality, whereas protection from cardiac mortality is limited to fish‐derived long‐chain n‐3 polyunsaturated fatty acids.Clinical Trial Registration

Findings from this nationwide, population-based, retrospective cohort study showed that the incidence of psychiatrist-diagnosed depression was significantly higher in female Taiwanese school-age children and adolescents with type 1 diabetes compared with those without the disease.
Objective
To study the utilization of dental care in patients with rheumatoid arthritis (RA) and compare the incidence of common dental disorders in patients with and without RA.
Methods
This data used in this study was from the population-based Taiwan's National Health Insurance Research Database. We identified 1337 patients with newly diagnosed RA between January 2000 and December 2012. We also identified 13,370 individual without a diagnosis of RA using frequency matching on 5-year age intervals, sex, and index year. Patients with a diagnosis of primary Sjögren's syndrome were excluded. Dental disorders were identified using respective ICD-9-CM codes confirmed by dentists. The incidence and incidence rate ratio [IRR] of each dental disorders were calculated using Poisson regression.
Results
Compared with the comparison cohort, the prevalence of dentist visits in the RA cohort were significantly higher (70.3% vs. 66.7%, p = 0.008) and the frequency of dentist visits in the RA cohort were also significantly higher (median 2.67 vs. 1.78 per year, p < 0.001). In addition, the incidence of visits for dental caries (adjusted IRR 1.16, p < 0.001), pulpitis (adjusted IRR 1.12, p = 0.044), gingivitis (adjusted IRR 1.13, p = 0.027), periodontitis (adjusted IRR 1.13, p = 0.004), and oral ulcer (adjusted IRR 1.24, p = 0.003) were higher in patients with RA.
Conclusions
An elevated prevalence and frequency of dental visits were associated with patients with RA. In addition, elevated incidence of dental disorders, including dental caries, pulpitis, gingivitis, periodontitis, and oral ulceration, were observed. Oral health should be accessed regularly in patients with RA.
