Abstract
Purpose
Neuromyelitis Optica Spectrum Disorder (NMOSD) is a rare disease with unknown risk factors. The role of oxidative stress and nutritional factors is imprecise in NMOSD development. Therefore, this paper aims to evaluate the effects of dietary total antioxidant capacity (TAC) on the odds of NMOSD.
Design/methodology/approach
Dietary TAC was determined in 70 definite NMOSD cases and 164 healthy controls in term of Ferric Reducing Antioxidant Power (FRAP) method. A validated 168-item semi-quantitative food frequency questionnaire (FFQ) was used for dietary assessment. Three multivariate regression models were applied to analyze the odds of NMOSD across the TAC quartiles.
Findings
A significant inverse association was found between dietary TAC and odds of being assigned to the NMOSD group in all three regression models. In the fully adjusted model ORs (95% CI) in the second, third and fourth quartiles of TAC vs the first quartile were as follows: 0.11 (0.04-0.29), 0.05 (0.01-0.16) and 0.01 (0.00-0.05), respectively. Odds of NMOSD also indicated a significant decreasing trend across the quartiles of dietary TAC (p-trend: <0.01). Total energy (p < 0.01) as well as consumption of vegetables (p < 0.01), whole grains (p < 0.01), tea and coffee (p < 0.01), legumes (p < 0.01) and poultry (p < 0.01) significantly increased through the TAC quartiles.
Originality/value
In the present study, a new hypothesis was proposed concerning the influence of dietary TAC on the odds of NMOSD. A diet rich in foods with high TAC can be effective in the modification of the NMOSD odds.

Abstract
Purpose
There is some evidence that suggest a higher dietary total antioxidant capacity (DTAC) is associated with a lower risk of metabolic syndrome (MetS). Considering the conflicting results in this field, this paper aims to provide a comprehensive summary of studies on the association of DTAC and components of MetS.
Design/methodology/approach
A systematic review of articles indexed in PubMed, Scopus and Google Scholar, published from inception to September 2018, with defined keywords, was done. Duplicate or irrelevant reports were screened out and data were extracted through critical analysis. Finally, among the 353 articles, 19 articles met the inclusion criteria.
Findings
The included cohort studies revealed that higher DTAC was associated with reduced risk of MetS. Also, the association between DTAC and mortality risk of MetS was insignificant in these studies. The case–control studies showed high DTAC is inversely associated with MetS, its components and complications. The randomized controlled trials found that changes in DTAC were negatively correlated with oxidized low-density lipoprotein cholesterol and there was a positive association between DTAC and subjects’ weight and body mass index. Finally, results from the cross-sectional studies were inconsistence in this regard.
Originality/value
The assessed relationship between MetS or its components with DTAC is inconsistent in the included studies. Different sample size, dietary assessment tools, DTAC index values and geographical location may justify the observed inconsistencies. It seems that further studies are needed to reveal more confident and reliable findings.

Abstract
Purpose
Social media has made a revolutionary change in the relationship between the customers and business or service providers by enabling customers to publish and share feedback and views about product or service quality. This revolutionary change has not been echoed in some healthcare systems. This study analyses the social media policies of healthcare regulatory authorities in Ontario and explores how these policies encourage or discourage healthcare professionals' use of social media for collecting patient stories and understanding patient experience.
Design/methodology/approach
The study used qualitative content analysis to analyse the policy documents, focusing on the manifest themes in these documents. It used convenient sampling to select 12 organizations, including regulating and licensing bodies and health service delivery organizations in Ontario. The authors collected 24 documents from these organizations, including policies, practice standards and social media learning materials.
Findings
In Ontario's healthcare system, social media is perceived as a source of risks to the healthcare professions and professionals. Healthcare regulators emphasize that the codes of conduct and professional standards extend to social media. The study found no systematic recognition of patient stories on social media as a source of information on healthcare quality that can be useful for healthcare professionals.
Originality/value
The study identifies potential unintended consequences of social media policies in the healthcare system and calls for policy and cultural changes to enable the development of safe social media platforms that can facilitate interaction between healthcare providers and patients, when necessary, without the fear of legal consequences or privacy breaches.
