Fatty acid quality indices (FAQIs) are novel determinants of QOL and may impact various aspects of QOL. Prior research has established a significant link between dietary habits and QOL. However, the association between FAQIs and specific dimensions of QOL has not been established. Therefore, we aimed to investigate the association between FAQIs and QOL in overweight and obese women.MethodsIn total, 378 adult overweight or obese women participated in this cross-sectional study. Several anthropometric indices, systolic and diastolic blood pressure, and biochemical factors were measured using standard protocols. Dietary intake was assessed using a validated and reliable semi-quantitative food frequency questionnaire (the FFQ, 147 items). The cholesterol–saturated fat index (CSI) and the ratio of omega-6/omega-3 (N6/N3) essential fatty acids consumed were employed as FAQIs. The SF...

We summarized evidence from randomized clinical trials (RCTs) that investigated the effects of melatonin on sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI) in adults with various diseases. Methods The literature searches of English publications in MEDLINE and EMBASE databases were performed up June 2020. Results were summarized as mean differences (MD) with 95% confidence intervals (CI) using random effects model (DerSimonian–Laird method). Heterogeneity among studies was evaluated by the Cochrane Q test and I-squared (I2). To determine the predefined sources of heterogeneity, subgroup analysis was performed. Results Of 2642 papers, 23 RCTs met inclusion criteria. Our results indicated that melatonin had significant effect on sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI) (WMD: − 1.24; 95% CI − 1.77, − 0.71, p = 0.000). There was significant heterogeneity between studies ( I 2 = 80.7%, p = 0.000). Subgroup analysis based on health status and kind of intervention were potential between-study heterogeneity. Subgroup analysis based on health status revealed melatonin intervention in subjects with Respiratory diseases (WMD: − 2.20; 95% CI − 2.97, − 1.44, p = 0.000), Metabolic disorders (WMD: − 2.74; 95% CI − 3.48, − 2.00, p = 0.000) and sleep disorders (WMD: − 0.67; 95% CI − 0.98, − 0.37, p = 0.000) has significant effect on sleep quality. Conclusion We found that the treatment with exogenous melatonin has positive effects on sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI) in adult. In adults with respiratory diseases, metabolic disorders, primary sleep disorders, not with mental disorders, neurodegenerative diseases and other diseases.

Evidence has shown that Interleukin (IL)-1β plays a substantial role in the neuro-immunity pathogenicity of migraine. n-3 fatty acids and curcumin revealed neuromodulatory and anti-inflammatory effects through several pathways, of which the suppression of IL-1β gene expression is an important inflammatory pathway. The aim of this study was the investigation of synergistic relation of n -3 fatty acids and nano-curcumin on IL-1β gene expression and serum levels in migraine patients. Methods: This study was performed as a randomized, double-blind, placebo-controlled trial in a period of two months. A total of 80 episodic migraines were assigned into 4 groups of 1) n-3 fatty acids and curcumin combination; 2) n -3 fatty acids; 3) nano-curcumin; and 4) n-3 fatty acids and curcumin placebo. The gene expression and serum level of IL-1β were measured by real-time PCR and ELISA methods respectively, at the beginning and the end of the interventions. Results: Results showed the n-3 fatty acids and nano-curcumin combination significantly reduced the attack frequency in a synergistic status (P <0.001). A significantly greater reduction in the serum level of IL-1β was observed in the combination group, and the differences in the other groups were not statistically significant. The IL-1β gene expression in the combination group showed a significant reduction for other treatment groups (P < 0.05), but these significant differences were absent after multiple testing Bonferroni corrections. Conclusion: Present findings revealed that n -3 fatty acids and curcumin co-supplementation can be suggested as a promising new approach in migraine headache management, but further studies are needed to confirm these findings.

Several human interventional studies have been conducted to assess the effects of blueberry intake on cognitive performance; however, the results of clinical trials are inconclusive. Therefore, this systematic review and meta-analysis evaluated the effect of blueberry supplementation on some aspects of cognitive performance and mood parameters using data from clinical trials based on existing evidence. Methods: Relevant studies, published in April 2021, were searched through PubMed/Medline, Scopus, Embase, and Google Scholar. The random effect size was used to estimate the pooled effect size. Heterogeneity between studies was evaluated by the Cochrane Q test and I-squared (I2). To detect the potential source of heterogeneity, a subgroup analysis was conducted. Results: Fourteenrandomized trials were included in the quantitative analysis, and six were pooled for statistical analysis. Blueberry intervention resulted in no significant change in mood state score (WMD = 0.03; 95% CI:-0.80 to 0.87, P = 0.16). Moreover, no significant effect of blueberry intake was shown in attention task reaction time (WMD = -1.50 ms; 95% CI:-24.75 to -21.75, P = 0.9), percentages of attention task accuracy (WMD = 0.85; 95% CI:-2.57 to 0.86, P = 0.3), one-back test accuracy (WMD = 0.03; 95% CI:-0.04 to 0.09, P = 0.4). Significant effect was indicated (WMD = 0.08; 95% CI: 0.02 to 0.13, P = 0.005) in two-back test accuracy. Conclusion: We found a significant effect of blueberry consumption on two-back test accuracy as a cognitive outcome. More high-quality clinical trials according to the challenges mentioned seem to indicate the use of blueberry as a supplement for cognitive and mood health efficiently.

However, it is not yet well proven that environmental modifications like improving the quality of beverage intake can be effective in people who have a genetic predisposition to obesity. So, in the present study, we examine the interaction between genetic predisposition and healthy beverage index (HBI) with abdominal obesity and obesity-related metabolic risk factors in overweight and obese women. Method Based on inclusion and exclusion criteria, 202 overweight or obese females were chosen for this cross-sectional study. Body composition, anthropometric measures, physical activity, and beverage intake data were collected and analyzed using recognized and trustworthy methodologies. Biochemical tests were performed on serum samples. A genetic risk score (GRS) was calculated based on the results of genetic tests. The predetermined HBI was calcu...

However, whether green tea supplementation leads to oxidative stress reduction remains unclear, as clinical investigations on this subject have yielded inconsistent outcomes. Consequently, we aimed to determine the effects of green tea supplementation on oxidative stress in adults. A systematic search of English language publications up to 21 August 2021 was carried out in PubMed, Scopus, Embase, and ISI Web of Science, utilizing pertinent keywords. These searches included randomized controlled trials (RCTs) evaluating the relationship between green tea supplementation, malondialdehyde (MDA), and total antioxidant capacity (TAC) in adults. A random-effects model was used to estimate the weighted mean difference (WMD) and 95% confidence intervals (95% CI). Meta-regression and non-linear dose-response analyses were performed to investigate the association between the dosage of green tea (mg/day) and the ...

The aim of this systematic review and meta- analysis of the observational studies was to clarify the association between migraine and obesity. Methods: Scopus and PubMed electronic databases were systematically searched up to February 2019 for observational studies providing data dealing with migraine disorder in obese subjects, as well as normal-weight controls. The random effects model was applied for assessing pool effect size, and inter-study heterogeneity was evaluated by conducting subgroup analyses. Results: Among 1122 publications, 16 studies (10 cross-sectional, 5 cohort studies and 1 case-control study) were detected and were included in the meta-analysis. The pooled data analysis illustrated an elevated risk of migraine headache (Prevalence ratio estimate = 1.29, 95% CI, 1.15 - 1.44, p = 0.000) in obese individuals compared to normal-...
