AI Article Synopsis
- Tamoxifen (TAM) is effective against breast cancer and gynecomastia but can harm male testicular function, prompting research on the protective effects of omega-3 fatty acids (O3FA).
- In a study with Wistar rats, TAM treatment led to negative impacts on sperm quality and hormonal imbalances, increasing testicular injury and oxidative stress.
- O3FA treatment showed potential in reversing TAM-induced testicular damage by influencing key cellular signaling pathways and reducing apoptosis in the testes.
Article Abstract
Background: Tamoxifen (TAM) is a widely used drug in patients with gynecomastia and breast cancer. TAM exerts its anticancer effects via its antiestrogenic activities. Unfortunately, TAM has been reported to exert gonadotoxic effects on male testes. Therefore, this study was designed to explore the possible associated mechanisms involved in TAM-induced testicular dysfunction and the possible ameliorative effects of omega-3 fatty acids (O3FA).
Methodology: Animals were randomly divided into control, O3FA, TAM, and TAM + O3FA. All treatment lasted for 28 days.
Results: TAM exposure impaired sperm qualities (count, motility, and normal morphology) and decreased testicular 3β-HSD and 17β-HSD. It was accompanied by a decline in serum testosterone and an increase in estradiol, luteinizing and follicle-stimulating hormones. These observed alterations were associated with an increase in testicular injury markers, oxido-inflammatory response, and mitochondria-mediated apoptosis. These observed alterations were ameliorated by O3FA treatments.
Conclusions: O3FA ameliorated TAM-induced testicular dysfunction in male Wistar rats by modulating XO/UA and Nrf2/NF-kb signaling and cytochrome c-mediated apoptosis in TAM-treated rats.

Omega-3 Polyunsaturated Fatty Acids in Chronic Obstructive Pulmonary Disease Patients with COVID-19: A Review.
Curr Nutr Rep
January 2025
Mind-Body Interface Research Center (MBI-Lab), China Medical University Hospital, Taichung, Taiwan.
Purpose Of The Review: Mounting evidence indicates that individuals with chronic obstructive pulmonary disease (COPD) face a heightened risk of severe outcomes upon contracting coronavirus disease 2019 (COVID-19). Current medications for COVID-19 often carry side effects, necessitating alternative therapies with improved tolerance. This review explores the biological mechanisms rendering COPD patients more susceptible to severe COVID-19 and investigates the potential of omega-3 polyunsaturated fatty acids (n-3 PUFAs) in mitigating the severity of COVID-19 in COPD patients.

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.

Long-term survival has improved in kidney transplant recipients (KTRs) due to effective surgical techniques and anti-rejection therapies. Chronic immunosuppression associated with it has led to several types of skin cancers leading to substantial morbidity and mortality. Structured patient education including sun protective behaviors, regular dermatological surveillance, nicotinamide, long-chain omega-3 polyunsaturated fatty acids (PUFAs), early switch to mammalian target of rapamycin inhibitors (mTORis), combining them with low-dose calcineurin inhibitors (CNIs), can decrease the cancer risk.

Introduction: The increasing adoption of strict vegetarian diets during pregnancy has raised concerns about their effects on maternal and neonatal outcomes. This systematic review and meta-analysis aimed to assess the impact of strict vegetarian diets on key pregnancy outcomes, including neonatal birth weight, small-for-gestational-age (SGA) infants, gestational diabetes mellitus (GDM), hypertensive disorders, and gestational weight gain (GWG).
Methods: A comprehensive literature search across multiple databases yielded eight studies from various countries, involving a total of 72,284 participants.

Purpose: Women in the decade before menopause are at risk for depression. This study describes dietary factors associated with depression risk in late premenopausal women that could be modifiable with targeted interventions.
Methods: Descriptive cross-sectional study comparing a community-based sample of 342 healthy premenopausal women categorized as low-risk and high-risk for depression in a secondary analysis of dietary variables.
