After paying homage to the work of E. Chevreul, Prof. Robert Gibson went on in a lighthearted way to find similarities in the way they both approached their respective fields of research, as well as their way of life. Prof. Robert Gibson, who was awarded the 2021 Chevreul Medal, reported that “his huge delight was to witness the massive growth of lipid research and to have played a role in elucidating the role of dietary fats in the health of mothers and their babies”. Prof. Gibson highlighted some of the major results he collected from Australian clinical studies conducted on the role of omega-3 fatty acids on the health outcomes of mothers and their infants. He first discussed the role of fish oil on visual acuity of babies and demonstrated that infant formulas supplying more than 1% of linolenic acid (ALA) seemed adequate to ensure optimal visual and cognitive development of term infants. However, in preterm infants, whether there is a specific need for DHA above the benefit provided by ALA, still needs to be clarified. He reported a small beneficial impact on the cognitive development of preterm infants receiving DHA enriched breast milk of their mothers (1% of total fatty acids). He then discussed data from his large randomised clinical trials conducted on pregnant women receiving a DHA dietary treatment (800 mg/d DHA) or placebo, that suggested that DHA may decrease the risk of preterm birth (DOMInO trial, 2400 women). This effect was confirmed in the ORIP trial (5400 women) which found that preterm birth could be prevented by a DHA supplement treatment mainly in women with a singleton pregnancy who had a low omega-3 status in the first trimester. In the last part of his review, Robert Gibson described the use of a new low cost, rapid and efficient method to monitor changes in blood levels of omega-3 fatty acids with clinical outcomes: the Dried Blood Spots (DBS) technology. The validation of this technique has been demonstrated in large trials like N3RO and ORIP involving large cohorts of women, which could not have been obtained easily by classical analysis of lipids. He went on to point out that free fatty acids (generally not explored despite their importance in many metabolic disorders) and oxylipins, are both stable and easily identified when they are preserved in a dry state on a paper matrix (DBS), thus opening new fields of research. To conclude, the major impact of Prof. Robert Gibson’s work was identifying and overcoming one of the causes of early preterm birth (omega-3 deficiency), developing a tool to rapidly assess omega-3 status (the DBS technique) that together is close to being implemented into the world health system.

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.

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).

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.
