Vitamin A biomarkers were associated with AGP and CRP over the course of a human norovirus challenge infection
Br J Nutr. 2023 Sep 11:1-19. doi: 10.1017/S0007114523002076. Online ahead of print.ABSTRACTRetinol binding protein (RBP) is used as a proxy for retinol in population-based assessments of vitamin A deficiency (VAD) for cost-effectiveness and feasibility. When the cutoff of <0.7 mol/L for retinol is applied to RBP to define VAD, an equivalence of the two biomarkers is assumed. Evidence suggests that the relationship between retinol and RBP is not 1:1, particularly in populations with a high burden of infection or inflammation. The goal of this analysis was to longitudinally evaluate the retinol:RBP ratio over one month of...

Role of Vitamins in Cardiovascular Health: Know Your Facts-Part 2
Curr Vasc Pharmacol. 2023 Sep 11. doi: 10.2174/1570161121666230911115725. Online ahead of print.ABSTRACTCardiovascular disease (CVD) is a major cause of morbidity/mortality world-wide, hence preventive interventions are crucial. Observational data showing beneficial CV-effects of vitamin supplements, promoted by self-proclaimed experts, have led to ~50% of Americans using multivitamins; this practice has culminated into a multi-billion-dollar business. However, robust evidence is lacking, and certain vitamins might incur harm. This two-part review focuses on the attributes or concerns about specific vitamin consumption on ...

Managing diabetic complications with alternative therapeutic strategies
Curr Diabetes Rev. 2023 Sep 7. doi: 10.2174/1573399820666230907112430. Online ahead of print.ABSTRACTDiabetes is a chronic metabolic disease affecting millions worldwide. It is characterized by a lack of insulin production or impaired insulin function, leading to elevated blood glucose levels. Conventional treatment methods for diabetes management typically include lifestyle changes and medications. However, alternative therapies have gained attention in recent years, including traditional medicine containing bioactive compounds, supplements like vitamin D and Omega-3 fatty acids, aromatherapy, and homeopathy. Diabetic com...

Influence of Vitamin D Deficiency on Cyclin D1-Induced Parathyroid Tumorigenesis
Endocrinology. 2023 Sep 11:bqad137. doi: 10.1210/endocr/bqad137. Online ahead of print.ABSTRACTPrimary hyperparathyroidism (PHPT) is a common endocrinopathy for which several pathogenic mechanisms, including cyclin D1 overexpression, have been identified. Vitamin D nutritional status may influence parathyroid tumorigenesis, but evidence remains circumstantial. To assess the potential influence of vitamin D insufficiency/deficiency on initiation or progression of parathyroid tumorigenesis, we superimposed vitamin D insufficiency or deficiency on parathyroid tumor-prone PTH-cyclin D1 transgenic mice. Mice were placed on diet...

Evaluation of Long-Term Nutrition Outcomes After Duodenal Switch: A Systematic Review and Meta-Analysis
CONCLUSIONS: Despite displaying comparable nutrition-related outcomes to mid-term follow-up, our study demonstrated that BPD-DS could result in a high level of long-term nutrition deficiency after BPD-DS for selected patients. However, further randomized controlled studies with standardized supplementation regimens and improvement in compliance are necessary to evaluate and prevent long-term nutritional deficiencies after BPD-DS.PMID:37694730 | DOI:10.1177/00031348231201886

Factors associated with depressive mood at the onset of multiple sclerosis - an analysis of 781 patients of the German NationMS cohort
CONCLUSION: Depressive symptoms need to be assessed in early MS. Patients during relapse seem especially vulnerable to depressive symptoms. Contributing factors such as fatigue, vitamin D deficiency and smoking, could specifically be targeted in future interventions and should be investigated in prospective studies.PMID:37692259 | PMC:PMC10492471 | DOI:10.1177/17562864231197309

National monitoring of iodine, sodium, and vitamin D status in toddlers and women of childbearing age - results and lessons learned from a pilot study in Norway
CONCLUSION: Lessons learned from the pilot study will be used to design a national monitoring program for toddlers and women of childbearing age in Norway. The results indicate that 2-year-old children and women of childbearing age in Norway may have inadequate iodine intakes at the group level, while for vitamin D, most of the mothers had adequate status.PMID:37691743 | PMC:PMC10492227 | DOI:10.29219/fnr.v67.9088

A Review on the Cytotoxicity and Antibacterial Effect of Marine Organisms of Persian Gulf
Adv Biomed Res. 2023 Jul 27;12:195. doi: 10.4103/abr.abr_290_22. eCollection 2023.ABSTRACTMarine organisms contain several natural products and bioactive compounds, including hydrolyzed proteins, antioxidant peptides, gelatin, collagen, ω-3 unsaturated fatty acids, vitamin A, vitamin D, calcium phosphate, hydroxyapatite, chitosan, lectin, and various toxins. They can inhibit diverse diseases, be used in pharmaceutical compounds, or as antibiotics and pigments. In this regard, these microorganisms are of crucial medicinal and economical importance. Thanks to new technologies and advanced laboratory methods, bioactive compo...
