The Impact

Viral infections are a leading cause of morbidity and mortality worldwide, and the importance of public health practices including handwashing and vaccinations in reducing their spread is well established. Furthermore, it is well known that proper nutrition can help support optimal immune function, reducing the impact of infections. Several vitamins and trace elements play an important role in supporting the cells of the immune system, thus increasing the resistance to infections. Other nutrients, such as omega-3 fatty acids, help sustain optimal function of the immune system. The main aim of this manuscript is to discuss of the potential role of micronutrients supplementation in supporting immunity, particularly against respiratory virus infections. Literature analysis showed that in vitro and observational studies, and clinical trials, highlight the important role of vitamins A, C, and D, omega-3 fatty acids, and zinc in modulating the immune response. Supplementation with vitamins, omega 3 fatty acids and zinc appears to be a safe and low-cost way to support optimal function of the immune system, with the potential to reduce the risk and consequences of infection, including viral respiratory infections. Supplementation should be in addition to a healthy diet and fall within recommended upper safety limits set by scientific expert bodies. Therefore, implementing an optimal nutrition, with micronutrients and omega-3 fatty acids supplementation, might be a cost-effective, underestimated strategy to help reduce the burden of infectious diseases worldwide, including coronavirus disease 2019 (COVID-19).

Objective This study aimed to evaluate the dose-response effects of supplemental omega-3 fatty acids on platelet function in healthy volunteers. Methods Twelve healthy volunteers ingested a normal supplemental dose of 1260 mg omega-3 fatty acids daily for 5 days, followed by a high dose of 2520 mg daily for another 5 days. Multiple electrode aggregometry (MEA) with four different agonists was used to measure platelet aggregation before and after the normal- and high-dose regimes. In vitro spiking using physiological doses of omega-3 fatty acids was also performed to determine whether MEA is capable of detecting a platelet-inhibiting effect due to omega-3 fatty acids. Results There were no differences in platelet aggregation measured by the MEA assay in healthy volunteers after intake of either the normal or high dose of omega-3 fatty acids. In the in vitro experiment, a platelet-inhibiting effect of omega-3 fatty acids was shown by an arachidonic acid agonist in MEA . Conclusions Supplemental omega-3 fatty acids do not evoke their positive health effects through inhibition of platelet aggregation measurable with MEA.

People with epilepsy have an increased risk of dying prematurely and the most common epilepsy-related category of death is sudden unexpected death in epilepsy (SUDEP). SUDEP is mainly a problem for patients with chronic uncontrolled epilepsy. The ultimate goal of research in SUDEP is to develop new methods to prevent it and actions other than medical and surgical therapies that could be very useful. Nutritional aspects, i.e., omega-3 fatty acids deficiency, could have an interesting role in this scenario. Some animal and clinical studies have suggested that omega-3 fatty acids could be useful in the prevention and treatment of epilepsy and hence SUDEP. It has been ascertained that the only foods that provide large amounts of omega-3 are seafood (fish and shellfish); however, some fish are contaminated with methylmercury, which may counteract the positive effects of omega-3 fatty acids. Our update review summarises the knowledge of the role of fish consumption on epilepsy research.

Omega 3 Fatty Acid

Introduction: The less prominent role of triglycerides in determining cardiovascular risk keeps these lipids from being top-of-mind for practicing clinicians, yet epidemiologic data affirm that hypertriglyceridemia contributes to atherosclerotic disease development and progression. We sought to determine if online continuing medical education (CME) could improve the clinical knowledge and competence of primary care physicians (PCPs) and cardiologists regarding hypertriglyceridemia and the use of omega-3 fatty acids in its treatment. Methods: The effects of two educational interventions about advances in hypertriglyceridemia treatment (activity 1) and educating patients about omega-3 fatty acid products (activity 2) were analyzed to determine efficacy of online education presented in the form of online video-based roundtable discussions. The activities launched online in May and June, 2015 respectively, and data were collected through July, 2015. The effects of education were assessed using knowledge- and case-based matched pre-assessment/post-assessments. The effect sizes were calculated with Cohen’s d (> 0.8 is large, 0.8-0.4 is medium, and < 0.4 is small). Results: In total, 842 PCPs and 75 cardiologists who completed all pre/post assessment questions in any of the two activities during the study period were included in analyses. Significant overall improvements were seen for PCPs (activity 1: n = 452, P <.05, effect d= 0.68; activity 2: n = 390, P <.05, effect d= 0.96) and cardiologists (activity 1: n = 35, P <.05, effect d= 0.77; activity 2: n = 40, P <.05, effect d= 0.9). Compared with baseline, specific areas of improvements include: • 22% more PCPs and 31% more cardiologists identified weight loss as a nonpharmacological intervention that can effectively lower triglyceride levels for overweight/obese patients with hypertriglyceridemia, (both P < .05) • 35% more PCPs and 32% more cardiologists identified the appropriate dosing of prescription omega-3 fatty acids (both P <.05) • 23% more PCPs ( P < .05) and 20% more cardiologists ( P =.068 ) recognized that reducing the risk for pancreatitis is a primary medical objective in patients with severe elevations in triglyceride levels Areas identified as needing additional education include: • 57% of all physicians remain unaware that omega-3 fatty acids reduce apolipoprotein C3 • 61% of PCPs and 60% of cardiologists did not demonstrate a thorough understanding of the differences between prescription omega-3 fatty acids and omega-3 supplements Conclusion: This study demonstrates the success of a targeted educational intervention with two educational components on improving knowledge, competence, and clinical decision-making of PCPs and cardiologists regarding hypertriglyceridemia treatment and the role of omega-3 fatty acid products in its treatment.

Omega-3 fatty acids are important to pregnancy and neonatal development and health. One mechanism by which omega-3 fatty acids exert their protective effects is through serving as substrates for the generation of specialized pro-resolving lipid mediators (SPM) that potently limit and resolve inflammatory processes. We recently identified that SPM levels are increased in maternal blood at delivery as compared to umbilical cord blood, suggesting the placenta as a potential site of action for maternal SPM. To explore this hypothesis, we obtained human placental samples and stained for the SPM resolvin D2 (RvD2) receptor GPR18 via immunohistochemistry. In so doing, we identified GPR18 expression in placental vascular smooth muscle and extravillous trophoblasts of the placental tissues. Using in vitro culturing, we confirmed expression of GPR18 in these cell types and further identified that stimulation with RvD2 led to significantly altered responsiveness (cytoskeletal changes and pro-inflammatory cytokine production) to lipopolysaccharide inflammatory stimulation in human umbilical artery smooth muscle cells and placental trophoblasts. Taken together, these findings establish a role for SPM actions in human placental tissue.
