[PMID: 38266360 PMCID: PMC11000149 DOI: 10.1016/j.maturitas.2024.107916] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 10/23/2023] [Accepted: 01/13/2024] [Indexed: 01/26/2024]
Abstract
Vitamin D status has been inconsistently associated with ovarian reserve and menopause. We used data from the Sister Study cohort to examine the associations of vitamin D supplement use, total 25-hydroxyvitamin D (25OHD) level, and calcium supplement use with the timing of natural menopause. Vitamin D and calcium supplement use were assessed on a questionnaire at baseline (mean age: 46) and two follow-up time points, and characterized in multiple ways based on type, dose, and duration of use. Serum samples from a random subset of participants were analyzed for total 25OHD (25OHD3 + 25OHD2 + epi-25OHD3) using liquid chromatography-mass spectrometry. Menopause was assessed at each yearly follow-up with the question "Have you had a menstrual period in the past 12 months?"; if the response was "no", age at last menstrual period was recorded. We censored women at time of hysterectomy or medically induced menopause, death, loss to follow-up or October 2020. We used multivariable Cox proportional hazard models with age as the time scale to estimate hazard ratios (HRs) and 95 % confidence intervals (CIs), adjusting for race/ethnicity, education, body mass index, alcohol use, smoking status, and physical activity. Among the 13,102 eligible premenopausal participants, 8897 experienced natural menopause during follow-up. Concomitant use of a multivitamin and a vitamin D supplement was associated with slightly earlier menopause (HR(CI): 1.10 (0.98, 1.24)). None of the remaining vitamin D or calcium supplement variables (alone or in combination) were meaningfully associated with timing of natural menopause. In a subsample with 25OHD measurements (n = 906), neither total 25OHD nor 25OHD3 was associated with timing of menopause. Our study includes, on average, 6 years of follow-up from an average age of 46 years and did not find associations between vitamin D or calcium supplement use and timing of menopause. Future studies should focus on a life course approach to this question and include 25OHD measures from early mid-life when examining menopause timing.

[PMID: 38070016 DOI: 10.1007/s00394-023-03280-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 11/08/2023] [Indexed: 02/28/2024]
Abstract
PURPOSE We assessed the cross-sectional association between healthy dietary patterns [alternate Mediterranean diet (aMED), Dietary Approaches to Stop Hypertension (DASH), alternative Healthy Eating Index (aHEI), and Healthy Eating Index 2015 (HEI-2015)] and urinary biomarkers of oxidative stress. METHODS Between 2003 and 2009, the Sister Study enrolled 50,884 breast cancer-free US women aged 35 to 74 (non-Hispanic White, 83.7%). Data were analyzed for 844 premenopausal and 454 postmenopausal women who had urine samples analyzed for F2-isoprostanes and non-missing covariate data. Food frequency questionnaire responses were used to calculate dietary pattern scores. Concentrations of 8-iso-prostaglandin F2α (8-iso-PGF2α) and its metabolite (8-iso-PGF2α-M) were measured in urine samples by GC/MS for premenopausal women and LC/MS for postmenopausal women. Multivariable linear regression models were used to estimate associations between aMED, DASH, aHEI, and HEI-2015 and urinary F2-isoprostanes by menopausal status. Effect modification by sociodemographic, lifestyle, and clinical characteristics was also evaluated. RESULTS Among premenopausal women, the four dietary indices were inversely associated with 8-iso-PGF2α (aMED βQ4vsQ1: - 0.17, 95% CI - 0.27, - 0.08; DASH βQ4vsQ1: - 0.18, 95% CI - 0.28, - 0.08; aHEI βQ4vsQ1: - 0.20, 95% CI - 0.30, - 0.10; HEI-2015 βQ4vsQ1: - 0.19, 95% CI - 0.29, - 0.10). In contrast, inverse associations with 8-iso-PGF2α-M were found for the continuous aMED, aHEI, and HEI-2015. Associations between dietary indices and 8-iso-PGF2α were generally stronger among younger women, women with lower income, and women with higher BMI. Similar results were observed among postmenopausal women, though only the continuous DASH and aHEI models were statistically significant. CONCLUSION Healthy dietary patterns were associated with lower levels of oxidative stress.

Abstract
Several different reactive oxygen species (ROS) are generated in vivo. They have roles in the development of certain human diseases whilst also performing physiological functions. ROS are counterbalanced by an antioxidant defence network, which functions to modulate ROS levels to allow their physiological roles whilst minimizing the oxidative damage they cause that can contribute to disease development. This Review describes the mechanisms of action of antioxidants synthesized in vivo, antioxidants derived from the human diet and synthetic antioxidants developed as therapeutic agents, with a focus on the gaps in our current knowledge and the approaches needed to close them. The Review also explores the reasons behind the successes and failures of antioxidants in treating or preventing human disease. Antioxidants may have special roles in the gastrointestinal tract, and many lifestyle features known to promote health (especially diet, exercise and the control of blood glucose and cholesterol levels) may be acting, at least in part, by antioxidant mechanisms. Certain reactive sulfur species may be important antioxidants but more accurate determinations of their concentrations in vivo are needed to help assess their contributions.

Prevention of aspirin-mediated secondary toxicity by combined treatment of carotenoids in macrophages. 3 Biotech 2023; 13:223. [PMID: 37292139 PMCID: PMC10244315 DOI: 10.1007/s13205-023-03632-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Accepted: 04/26/2023] [Indexed: 06/10/2023] Open
Abstract
Upon understanding the boosting role of carotenoids on the endogenous anti-inflammatory system, it is vital to explore their role in reducing the use of high doses of non-steroidal anti-inflammatory drug (NSAIDs), and their mediated secondary toxicity during the treatment of chronic diseases. The current study investigates the carotenoids potential on inhibition of secondary complications induced by NSAIDs, aspirin (ASA) against lipopolysaccharide (LPS) stimulated inflammation. Initially, this study evaluated a minimal cytotoxic dose of ASA and carotenoids (β-carotene, BC/lutein, LUT/astaxanthin, AST/fucoxanthin FUCO) in Raw 264.7, U937, and peripheral blood mononuclear cells (PBMCs). In all three cells, carotenoids + ASA treatment reduced the LDH release, NO, and PGE2 efficiently than an equivalent dose of carotenoid or ASA treated alone. Based on cytotoxicity and sensitivity results, RAW 264.7 cells were selected for further cell-based assay. Among carotenoids, FUCO + ASA exhibited an efficient reduction of LDH release, NO, and PGE2 than the other carotenoids (BC + ASA, LUT + ASA, and AST + ASA) treatment. FUCO + ASA combination decreased LPS/ASA induced oxidative stress, pro-inflammatory mediators (iNOS, COX-2, and NF-κB), and cytokines (IL-6, TNF-α, and IL-1β) efficiently. Further, apoptosis was inhibited by 69.2% in FUCO + ASA, and 46.7% in ASA than LPS treated cells. A drastic decrease in intracellular ROS generation with the increase in GSH was observed in FUCO + ASA compared to LPS/ASA groups. The results documented on the low dose of ASA with a relative physiological concentration of FUCO suggested greater importance for alleviating secondary complications and optimize prolonged chronic disease treatments with NSAID's associated side effects.
