The neuroprotective effect of lutein was associated with reduced oxidative stress. Lutein has been hitherto used principally for protection of outer retinal elements in AMD. Our study suggests that it may also be relevant for the protection of inner retina from acute ischemic damage.

Aim Eating disorders have increasingly become a public health concern globally. This study aimed to reveal the burden of eating disorders at the global, regional and national levels using the Global Burden of Disease (GBD) Study 2017 data. Methods We extracted the age-standardised rates (ASRs) of prevalence and disability-adjusted life years (DALYs) and their 95% uncertainty intervals (UIs) of eating disorders, including anorexia nervosa and bulimia nervosa, between 1990 and 2017 from the GBD 2017 data. The estimated annual percentage changes (EAPCs) were calculated to quantify the secular trends of the burden of eating disorders. Results The ASRs of prevalence and the DALYs of eating disorders continuously increased worldwide from 1990 to 2017 by an average of 0.65 (95% UI: 0.59–0.71) and 0.66 (95% UI: 0.60–0.72), respectively. The burden of eating disorders was higher in females than in males, but the increment in ASRs was greater in males than in females over time. In 2017, the highest burden of eating disorders was observed in the high sociodemographic index (SDI) regions, especially Australasia (ASR of prevalence = 807.13, 95% UI: 664.20–982.30; ASR of DALYs = 170.74, 95% UI: 113.43–244.14, per 100 000 population), Western Europe and high-income North America. However, the most significant increment of the burden of eating disorders was observed in East Asia (EAPC for prevalence = 2.23, 95% UI: 2.14–2.32; EAPC for DALYs = 2.22, 95% UI: 2.13–2.31), followed by South Asia. An increasing trend in the burden of eating disorders at the national level was observed among most countries or territories. The countries with the top three highest increasing trends were Equatorial Guinea, Bosnia and Herzegovina and China. Positive associations were found between the burden estimates and the SDI levels in almost all geographic regions during the observed 28-year period. We also found that the human development indexes in 2017 were positively correlated with the EAPCs of the ASRs of prevalence (ρ = 0.222, P = 0.002) and DALYs (ρ = 0.208, P = 0.003). Conclusion The highest burden of eating disorders remains in the high-income western countries, but an increasing trend was observed globally and in all SDI-quintiles, especially in Asian regions that were highly populous. These results could help governments worldwide formulate suitable medical and health policies for the prevention and early intervention of eating disorders.

Objective To evaluate the effectiveness of using WeChat platform to manage the patients with H. pylori infection. Methods 566 patients were randomly divided into two groups: The control group was treated with traditional management method, and the experimental group established WeChat group and implemented the informatization management. The two groups were given a unified plan to eradicate H. pylori. After the treatment, the C14 breath test was reexamined. The follow‐up rate and H. pylori eradication rate of the two groups were counted. Results In the experimental group, 289 patients were enrolled and 271 patients were followed up. The follow‐up rate was 93.8%. The number of H. pylori‐negative patients was 244, and the eradication rate was 90.0%. In the control group, 277 patients were enrolled in the study, and 215 patients were followed up. The follow‐up rate was 77.6%. 169 cases of H. pylori‐negative conversion were found, and the eradication rate was 78.6%. Conclusion Through WeChat management, the medication adherence, regular follow‐up, and H.pylori infection eradication rate of the patients with H.pylori infection in the experimental group were better than that in control group, during the treatment of eradicating H.pylori, and the difference was statistically significant.
