Do Micronutrient and Omega-3 Fatty Acid Supplements Affect Human Maternal Immunity during Pregnancy? A Scoping Review

Safety evaluation of alpha-glycerylphosphorylcholine as a novel food

To evaluate the safety of alpha-glycerylphosphorylcholine (α-GPC) as a novel food, the study of acute oral toxicity, subchronic toxicity, teratogenic toxicity and genotoxicity were conducted. In acute oral toxicity, no toxic effects were observed in rats of both genders administrated 10.0 g/kg BW α-GPC. In 90-day oral toxicity, female high-dose group (2,000 mg/kg) had lower body weight, body weight gain, empty stomach body weight, total protein (TP), albumin (ALB), and higher alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) in contrast to control group. In teratogenic toxicity, the body weights of pregnant rats on the 9th day (d9), the 12th day (d12), the 15th day (d15), and the 20th day (d20), body weight gains, and net body weight gains in high-dose group (2,000 mg/kg) decreased, the other parameters had no difference compared to control group. In genotoxicity tests (Mammalian erythrocyte micronucleus, Chromosome aberration and Ames test), all dose groups didn't display significant change compared with negative control group. Based on above results, α-GPC is actually low hazard novel food, has a NOAEL of 1,000 mg/kg BW for female rats and 2,000 mg/kg BW for male rats following 13-week oral exposure, has a NOAEL of 1,000 mg/kg BW for pregnant rats and 2,000 mg/kg BW for fetal rats in teratogenic toxicity, has no genotoxicity in vitro or in vivo.

The Impact of Parental Preconception Nutrition, Body Weight, and Exercise Habits on Offspring Health Outcomes: A Narrative Review

An increasing number of studies highlight the critical role of both maternal and paternal nutrition and body weight before conception in shaping offspring health. Traditionally, research has focused on maternal factors, particularly in utero exposures, as key determinants of chronic disease development. However, emerging evidence underscores the significant influence of paternal preconception health on offspring metabolic outcomes. While maternal health remains vital, with preconception nutrition playing a pivotal role in fetal development, paternal obesity and poor nutrition are linked to increased risks of metabolic disorders, including type 2 diabetes and cardiovascular disease in children. This narrative review aims to synthesize recent findings on the effects of both maternal and paternal preconception health, emphasizing the need for integrated early interventions. The literature search utilized PubMed, UNF One Search, and Google Scholar, focusing on RCTs; cohort, retrospective, and animal studies; and systematic reviews, excluding non-English and non-peer-reviewed articles. The findings of this review indicate that paternal effects are mediated by epigenetic changes in sperm, such as DNA methylation and non-coding RNA, which influence gene expression in offspring. Nutrient imbalances during preconception in both parents can lead to low birth weight and increased metabolic disease risk, while deficiencies in folic acid, iron, iodine, and vitamin D are linked to developmental disorders. Additionally, maternal obesity elevates the risk of chronic diseases in children. Future research should prioritize human studies to explore the influence of parental nutrition, body weight, and lifestyle on offspring health, ensuring findings are applicable across diverse populations. By addressing both maternal and paternal factors, healthcare providers can better reduce the prevalence of metabolic syndrome and its associated risks in future generations.

Latest research in nootropic therapy of patients with chronic cerebral circulation insufficiency

OBJECTIVE

Aim: To analyze latest research on the usage of choline alfoscerate and ethylmethylhydroxypyridine succinate (EMHPS) as nootropic therapy for patients with chronic cerebral circulation insufficiency (CCCI).

PATIENTS AND METHODS

Materials and Methods: Bibliosemantic, comparative and system analysis methods were used in the study. The proposed recommendations are developed on the basis of the analysis of modern literature, the results of randomized studies and meta-analyses, authoritative studies devoted to the study of the CCCI problem.

CONCLUSION

Conclusions: The combination of EMHPS with choline alfoscerate for the complex treatment of CCCI and associated syndromes improves the functions of the endothelium, leads to asthenic syndrome, indicators of stress, depression and anxiety decreasing has a positive effect on the cognitive impairment and complications' progress reduction.

Omega-3 fatty acid supplements and recurrent miscarriage: A perspective on potential mechanisms and clinical evidence

Recurrent miscarriage (RM) affects approximately 1%-5% of couples worldwide. Due to its complicated etiologies, the treatments for RM also vary greatly, including surgery for anatomic factors such as septate uterus and uterine adhesions, thyroid modulation drugs for hyperthyroidism and hypothyroidism, and aspirin and low molecular weight heparin for antiphospholipid syndrome. However, these treatment modalities are still insufficient to solve RM. Omega-3 fatty acids are reported to modulate the dysregulation of immune cells, oxidative stress, endocrine disorders, inflammation, etc., which are closely associated with the pathogenesis of RM. However, there is a lack of a systematic description of the involvement of omega-3 fatty acids in treating RM, and the underlying mechanisms are also not clear. In this review, we sought to determine the potential mechanisms that are highly associated with the pathogenesis of RM and the regulation of omega-3 fatty acids on these mechanisms. In addition, we also highlighted the direct and indirect clinical evidence of omega-3 fatty acid supplements to treat RM, which might encourage the application of omega-3 fatty acids to treat RM, thus improving pregnancy outcomes.

Choline supplements: An update

In this comprehensive review, we examine the main preclinical and clinical investigations assessing the effects of different forms of choline supplementation currently available, including choline alfoscerate (C₈H₂₀NO₆P), also known as alpha-glycerophosphocholine (α-GPC, or GPC), choline bitartrate, lecithin, and citicoline, which are cholinergic compounds and precursors of acetylcholine. Extensively used as food supplements, they have been shown to represent an effective strategy for boosting memory and enhancing cognitive function.
