Metabolic syndrome is a multifactorial disorder and genetics, lifestyle, and aging play important roles in its prevalence. Nigella sativa has several pharmacological benefits, including anti-inflammatory, antitumor, anti-diabetic, antioxidant, and hypolipidemic effects. This meta-analysis of randomized controlled trials assesses the effect of N. sativa consumption on lipid profile and glycemic indices in patients with metabolic syndrome. We systematically researched Cochrane Library, PubMed, Scopus, and Web of Science databases. The literature research identified 171 studies with duplication. Of those, 73 articles were screened for titles and abstracts, and 7 studies were finally selected for the meta-analysis. Because of the high degree of heterogeneity, we performed subgroup analyses based on the dose of N. sativa (<=500 mg/day or >500 mg/day). The results revealed that N. sativa intake significantly decreased total cholesterol (SMD: -0.71; 95% CI, -1.44 to -0.38; P = 0.00), LDL-C (SMD: -1.06; 95% CI, -1.45 to -0.66; P = 0.00) and HDL-C (SMD: -0.31; 95% CI, 0.09 to 0.53; P = 0.01) concentrations. In addition, N. sativa significantly decreased FBS (SMD: -0.8; 95% CI, -1.21 to -0.39; P = 0.00) and HbA1c (SMD: -0.37; 95% CI, -0.66 to -0.09; P = 0.01) concentrations. No publication bias was observed, and sensitivity analysis showed stable results. The current systematic review and meta-analysis indicates that N. sativa could improve lipid profile and glycemic index in patients with metabolic syndrome.

Protective factors for adverse childhood experiences: Scoping review and evidence gap map.

Adverse childhood experiences (ACES) negatively impact mental, physical, and behavioral health of adults. To develop empirically supported interventions to reduce the impact of ACES, we need to have a strong empirical base of research on modifiable protective factors that reduce the link between ACES and health outcomes. The current review is focused on assessing the state of the literature on modifiable protective factors on the ACE-health outcome relationship in adults. We conducted a scoping review in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. A systematic search for peer-reviewed literature published in English was conducted in Medline, Embase, PsycINFO, CINAHL, and Web of Science from inception of the databases to January 5, 2023. We then constructed an evidence gap map to provide an innovative, visual approach to guide research prioritization. Seventy-seven articles met inclusion criteria. Findings indicated that the majority focused on mental health outcomes (59%), and investigated individual (52%) and general social support (23%) protective factors. Also, the majority of the work was done in North America (65%) with predominantly female samples. Future studies should focus on addressing gaps in our understanding of what factors may buffer the influence of ACES on physical health outcomes and risky health behaviors and our understanding of family and nonfamily relationships and community and cultural protective factors on the ACE-health outcome relationship in adults. Additionally, research is needed that focuses on samples that are more gender diverse and from countries outside of North America. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Emerging Phytochemical Formulations for Management of Rheumatoid Arthritis: A Review.

Rheumatoid arthritis (RA) is a T-cell-mediated chronic inflammatory disorder affecting 0.5-1% of the global population. The disease with unknown etiology causes slow destruction of joints, advancing to significant deterioration of an individual's quality of life. The present treatment strategy comprises the use of disease-modifying anti-rheumatic drugs (DMARDs) coupled with or without nonsteroidal anti-inflammatory drugs or glucocorticoids. Additionally, involves co-therapy of injectable biological DMARDs in case of persistent or recurrent arthritis. The availability of biological DMARDs and the implementation of the treat-to-target approach have significantly improved the outcomes for patients suffering from RA. Nevertheless, RA requires continuous attention due to inadequate response of patients, development of tolerance and severe side effects associated with long-term use of available treatment regimens. An estimated 60-90% of patients use alternative methods of treatment, such as herbal therapies, for the management of RA symptoms. Over the past few decades, researchers have exploring natural phytochemicals to alleviate RA and associated symptoms. Enormous plant-origin phytochemicals such as alkaloids, flavonoids, steroids, terpenoids and polyphenols have shown anti-inflammatory and immunomodulatory activity against RA. However, phytochemicals have certain limitations, such as high molecular weight, poor water solubility, poor permeability, poor stability and extensive first-pass metabolism, limiting absorption and bioavailability. The use of nanotechnology has aided to extensively improve the pharmacokinetic profile and stability of encapsulated drugs. The current review provides detailed information on the therapeutic potential of phytochemicals. Furthermore, the review focuses on developed phytochemical formulations for RA, with emphasis on clinical trials, regulatory aspects, present challenges, and future prospects.
