Background And Aim: The effect of tamoxifen administration on serum lipids in females remains unclear. The studies which have explored this topic have produced conflicting results, probably due to discrepancies in the length of the intervention, differences in baseline variables or other factors. To answer this research question, we decided to conduct this systematic review and meta-analysis to assess the effects of tamoxifen on the lipid profile in women.

Methods: A comprehensive search was conducted in Web of Science, Scopus, PubMed/Medline and Embase, from the inception of these databases up to June 2021. We used a random effects meta-analysis to generate the combined results.

Results: The overall findings were generated from 18 eligible trials. As compared to placebo, tamoxifen led to a notable reduction of the total cholesterol (TC) (WMD: -23.03 mg/dL, 95% CI: -25.94 to -20.12, P˂0.001), and the low-density lipoprotein-cholesterol (LDL-C) (WMD: -18.68 mg/dL, 95% CI: -24.31 to -13.04, P˂0.001). However, tamoxifen did not alter triglycerides (TG) concentrations (WMD: +1.06 mg/dL, 95% CI: -11.08 to 13.20, P = 0.864) significantly. A pronounced reduction of the high-density lipoprotein-cholesterol (HDLC) was noted in the RCTs with a duration of ≤52 weeks (WMD: -2.06 mg/dL) and when tamoxifen was administered in participants with a BMI ≥25 kg/m (WMD: -1.42 mg/dL). Notable reductions in TC (WMD: -23.57 mg/dL) and LDL-C (WMD: -19.21 mg/dL) was detected when the dose of tamoxifen was ≥20 mg/day. Moreover, a significant reduction of TC (WMD: -20.23 mg/dL) and LDL-C (WMD: -24.13 mg/dL) was observed in the RCTs with a duration of ≤52 weeks.

Conclusion: Tamoxifen can alter the lipid profile in females, particularly by decreasing TC, LDL-C and HDLC. Tamoxifen can further reduce TC and LDL-C if the dose of administration is ≥20 mg/day, the treatment duration is ≤52 weeks and if it prescribed in subjects with dyslipidemia.

Cadmium is a heavy metal contaminant known to cause various health issues. However, limited research exists on the serum metabolomic effects of cadmium exposure in children. In this study, we recruited 42 children to analyze their serum metabolomic profiles, along with measuring urinary cadmium and creatinine concentrations, to evaluate the impact of environmental cadmium exposure on serum metabolism.

This study explores the therapeutic potential of ω-3 algal oil (rich in DHA) and ω-7 sea buckthorn oil (rich in palmitoleic acid) in addressing hyperlipidemia and associated metabolic disorders. These oils regulate lipid metabolism through the PPARγ-LXRα-ABCA1/ABCG1 signaling pathway, reducing cholesterol accumulation, oxidative stress, and inflammation. In high-fat diet-induced hyperlipidemic mice, supplementation with these oils significantly improved lipid profiles, alleviated hepatic steatosis, and promoted cardiovascular health.

Background/aim: The purpose of this study was to examine the hepatic bacterial composition and metabolome characteristics of patients with NAFLD using 16S rDNA sequencing and metabolomics. The results of the study revealed substantial differences in hepatic bacterial composition and metabolites between the NAFLD group and the control group. These differences were used to identify potential biomarkers that could be employed to diagnose NAFLD.

Capsicum oleoresin (CO) is a concentrated extract derived from peppers ( L.) containing capsaicin (the active compound responsible for its pungency) and other bioactive components. The present study aimed to determine whether CO affects the energy expenditure and mitochondrial content of brown adipose tissue (BAT) in diet-induced obese mice.

This study investigated the biochemical composition and tested the antioxidant and antimicrobial properties of four Indian-origin essential oils (EOs)-ginger, garlic, clove, and eucalyptus-to evaluate their potential for culinary applications. Gas chromatography-mass spectrometry (GC-MS) analysis was used to identify the chemical constituents of EOs. Antioxidant assays such as 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) and antimicrobial assays such as Agar well diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) were carried out.
