Omega-3 fatty acids and blood-based biomarkers in Alzheimer's disease and mild cognitive impairment: A randomized placebo-controlled trial.

BACKGROUND: Increased serum levels of pro-inflammatory biomarkers are consistently associated with cognitive decline. The omega-3 unsaturated fatty acids (n-3 PUFAs) had been linked to slowing cognitive decline due to their potential anti-inflammatory effects. To our knowledge, the different regiments of pure DHA, pure EPA, and their combination on various associated symptoms of dementia, including a mild form of cognitive impairment (MCI) and Alzheimer's disease (AD), have never been studied. METHODS: This multisite, randomized, double-blind, placebo-controlled trial was conducted at two veteran's retirement centers and one medical center in central Taiwan between 2013 and 2015. 163 MCI or AD patients were randomly assigned to placebo (n = 40), docosahexaenoic acid (DHA, 0.7 g/day, n = 41), eicosapentaenoic acid (EPA, 1.6 g/day, n = 40), or EPA (0.8 g/day) + DHA (0.35 g/day) (n = 42) group for 24 months. The results were measured as the cognitive and functional abilities, biochemical, and inflammatory cytokines profiles. Chi-square tests, two-sample t-test, ANOVA, and linear mixedeffects models were conducted with p < 0.05. RESULTS: 131 (80%) participants had completed the trial with all cognitive, functional, and mood status assessments. The statistically significant difference between the placebo and treatment groups was not determined, concerning the changes in cognitive, functional, and mood status scores, the biochemical profiles, and inflammatory cytokines levels. However, EPA was found to reduce the C-C motif ligands 4 (CCL4) level (p < 0.001). Additionally, EPA could reduce the constructional praxis (p < 0.05) and spoken language ability scores (p < 0.01), and DHA also reduced the spoken language ability score (p < 0.05). CONCLUSION: Overall, n-3 PUFAs supplements did not reduce cognitive, functional, and depressive symptom outcomes, but spoken language ability and constructional praxis subitems of ADAS-cog. These findings show that attention to clinical heterogeneity in dementia is crucial when studying nutrients interventions, such as n-3 PUFAs. In addition, with small effect size CCL4 is a better indicator than other inflammatory cytokines for EPA treatment response.

Evaluation of the efficacy of traditional Chinese medicine for the reproductive and pregnancy outcomes in women with endometriosis: A nationwide population-based study.

OBJECTIVE: Patients with endometriosis may seek traditional Chinese medicine (TCM) to help them conceive. The present study aims to evaluate the effects of TCM on reproductive and pregnancy outcomes in patients with endometriosis. MATERIALS AND METHODS: The patients with endometriosis taken from the National Health Insurance (NHI) research database between 2000 and 2012 were divided into two cohorts based on the use of TCM treatment. The two cohorts were matched by age and comorbidities and followed up until a new diagnosis of infertility, ectopic pregnancy, or miscarriage. Multivariable Cox proportional hazards models were used to evaluate the hazard ratio (HR) of reproductive and pregnancy outcomes. RESULTS: A total of 5244 patients with endometriosis were analyzed, including 1748 TCM users and 3496 matched control subjects. The proportion of infertility was higher in TCM users than in non-TCM users (adjusted hazard ratio [HR]: 1.34, 95% confidence interval [CI]: 1.13-1.60). However, there was no significant difference in the proportion of ectopic pregnancies between TCM users and non-TCM users (adjusted HR: 0.82, 95% CI: 0.60-1.13). There was no significant difference in the proportion of miscarriages between TCM users and non-TCM users (adjusted HR: 1.23, 95% CI: 0.95-1.61). CONCLUSION: TCM treatment showed insignificant efficacy in decreasing the risk of ectopic pregnancy and miscarriage in patients with endometriosis.

Evaluation of the efficacy of Chinese herbal medicine and acupuncture for the prevention of mental disorders in interstitial cystitis patients: A nationwide population-based study.

Traditional Chinese medicine (TCM) is commonly used for urinary symptoms in Eastern countries. Since there are few effective treatments available for patients with interstitial cystitis/bladder pain syndrome (IC/BPS), the psychological burden leads to increased healthcare-seeking behavior. Some patients may therefore seek TCM treatment for related urinary symptoms. Due to limited clinical research evaluating the effects of TCM on IC/BPS, we conducted a nationwide population-based cohort study to investigate the relationship between TCM and mental disorders among these patients. The IC/BPS cohort and its matched non-IC/BPS comparison cohort were recruited from the National Health Insurance (NHI) Research Database between 2000 and 2011. Patients with the use of Chinese herbal medicine (CHM) granules or acupuncture over 90 days per year were enrolled as the TCM users. Multivariable Cox proportional hazards models were used to evaluate the hazard ratio (HR) of mental disorders related to interstitial cystitis. The incidence of mental disorders in the 2 cohorts was assessed with Kaplan-Meier curves. A total of 1123 patients with IC/BPS and 4492 matched non-IC/BPS subjects were included in this study. The IC/BPS cohort demonstrated higher incidence rate of mental disorders than the cohort without IC/BPS (adjusted HR: 2.21, 95% confidence interval [CI]: 1.73-2.81). There was no statistically significant difference in the risk of mental disorders between IC/BPS patients with and without CHM granules or acupuncture treatment (adjusted HR: 0.99, 95% CI: 0.58-1.68). Our results indicated that CHM and acupuncture showed insignificant efficacy in the prevention of mental disorders in IC/BPS patients.
