Effect of curcumin supplementation on symptoms of anxiety: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND AIM: Curcumin is a polyphenolic natural compound that has been used to treat various ailments such as symptoms of anxiety. However, the findings of studies regarding the anti-anxiety properties of curcumin are controversial. This review aims to evaluate if there are clinical benefits of curcumin in patients with symptoms of anxiety. METHODS: PubMed, Embase, Web of Science, and the Cochrane Library were retrieved to collect randomized controlled trials (RCTs) from the database inception to August 16, 2023. The random-effects model was used to estimate the standard mean difference (SMD). RESULTS: A total of eight RCTs involving 567 participants were included in the analysis. A pooled analysis showed a significant effect of curcumin on anxiety symptoms (SMD: -1.56; 95% CI: -2.48, -0.64, p < 0.001; I2 = 95.6%, p-heterogeneity< 0.001). CONCLUSION: Present meta-analysis demonstrated that curcumin intake might contribute to alleviation of anxiety disorder. Due to the limited number of studies included, it is necessary to conduct more high-quality studies to confirm the clinical efficacy of curcumin.

Effects of Nigella sativa supplementation on lipid profiles in adults: An updated systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND AIM: Several experiments have suggested that Nigella sativa (N. sativa) supplementation may have a beneficial effect on the lipid profile. However, the results from these trials have been inconclusive. Therefore, this study aimed to explore the impact of N. sativa supplementation on the lipid profile of adult participants. METHODS: We searched Scopus, Web of Science, PubMed, Cochrane, and Web of Science databases until December 2022. Random effects models were used, and pooled data were determined as standardized mean differences with a 95% confidence interval. RESULTS: The findings of 34 studies with 2278 participants revealed that N. sativa supplementation significantly reduced total cholesterol (TC) (SMD: -1.78; 95% CI: -2.20, -1.37, p < 0.001), triglycerides (TG) (SMD: -1.2725; 95% CI: -1.67, -0.83, p < 0.001), and low-density lipoprotein cholesterol (LDL-C) (SMD: -2.45; 95% CI: -3.06, -1.85; p < 0.001) compared to control groups. However, a significant increase was found in high-density lipoprotein cholesterol (HDL-C) (SMD: 0.79; 95% CI: 0.38, 1.20, p < 0.001). CONCLUSION: N. sativa has improved effects on TG, LDL-C, TC, and HDL-C levels. Overall, N. sativa may be suggested as an adjuvant anti-hyperlipidemic agent.

The status of Iranian hospital pharmacies according to age-friendly pharmacies criteria.

Due to the increasing elderly population and the subsequent increase in their need for medication and more referrals to the pharmacy, this study was conducted to investigate the Iranian hospital pharmacies in terms of age-friendliness criteria. This was a cross-sectional study conducted in 2017. The study population included 3 metropolitan hospital pharmacies selected through clustered sampling, and all their 67 pharmacies were included by census. Data collection tool was a reliable researcher-made checklist (t = 0.85, α = 0.9) Data analysis was performed using Kruskal-Wallis test and Mann-Whitney test through SPSS version 24. The results in these three cities showed that only two pharmacies were in a high level of age-friendly. The relationship between type of pharmacy and the final score of age-friendly situation in these cities showed no significant relationship. There was no significant relationship among the average of the final score of the age-friendly situation in three studied cities. Due to the increasing elderly population and the aging society, readiness of Iranian hospital pharmacies to provide services to the elderly will be one of the most challenging issues in the long term. With proper legislation and policies on health-care systems, especially pharmacies, physical and psychological problems in elderly can be reduced in the future. Furthermore, with advancing toward age-friendly pharmacies, the community can be empower and become ready encountering elderly problems.

An Evidence-Based Review on Wound Healing Herbal Remedies From Reports of Traditional Persian Medicine.

Research on wound healing agents is a developing area in biomedical sciences. Traditional Persian medicine is one of holistic systems of medicine providing valuable information on natural remedies. To collect the evidences for wound-healing medicaments from traditional Persian medicine sources, 5 main pharmaceutical manuscripts in addition to related contemporary reports from Scopus, PubMed, and ScienceDirect were studied. The underlying mechanisms were also saved and discussed. Totally, 65 herbs used in traditional Persian medicine for their wound healing properties was identified. Related anti-inflammatory, antioxidant, antimicrobial, and wound-healing activities of those remedies were studied. Forty remedies had at least one of those properties and 10 of the filtered plants possessed all effects. The medicinal plants used in wound healing treatment in traditional Persian medicine could be a good topic for further in vivo and clinical research. This might lead to development of effective products for wound treatment.
