Background: High oxidative stress, which is caused by smoking, can alter omega-3 fatty acid concentrations. Since omega-3 fatty acids play a role in dopaminergic neurotransmission related to dependence, it is important to understand their effects on nicotine dependence. Methods: This research comprised 2 studies. The first one consisted of a cross-sectional evaluation, in which the levels of the most important omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), were compared between smokers and non-smokers in a sample of 171 individuals; of them, 120 were smokers and 51 were non-smokers. The other study was a clinical, double-blind, randomized, placebo controlled, in which 63 smokers received daily treatment with capsules of fish oil (a source of omega-3/3 g/day) or mineral oil (used as placebo, also 3 g/day), taken 3 times a day for 90 days. Each fish oil capsules contained approximately 210.99 mg EPA and 129.84 mg of DHA. The outcome was evaluated by means of psychometric and biological measures as well as self-reports of tobacco use. The evaluations were carried out at the beginning of treatment and once a month thereafter (total of 4 times). Outcomes: The omega-3 fatty acid lipid profile showed that smokers present lower concentrations of DHA. After treatment, the omega-3 group showed a significant reduction in their levels of dependence. Interpretation: Smokers showed lower peripheral levels of omega-3, and treatment with the most important omega-3 fatty acids brought about a reduction in nicotine dependence.

Baltic herring (Clupea harengus membras) is one of the most abundant commercially caught fish species from the Baltic Sea. Despite the high content of fat and omega-3 fatty acids, the consumption of Baltic herring has decreased dramatically over the last four decades, mostly due to the small sizes and difficulty in processing. At the same time there is an increasing global demand for fish and fish oil rich in omega-3 fatty acids. This study aimed to investigate enzyme-assisted oil extraction as an environmentally friendly process for valorizing the underutilized fish species and by-products to high quality fish oil for human consumption. Three different commercially available proteolytic enzymes (Alcalase®, Neutrase® and Protamex®) and two treatment times (35 and 70 min) were investigated in the extraction of fish oil from whole fish and by-products from filleting of Baltic herring. The oil quality and stability were studied with peroxide- and p-anisidine value analyses, fatty acid analysis with GC-FID, and volatile compounds with HS-SPME-GC-MS. Overall, longer extraction times led to better oil yields but also increased oxidation of the oil. For whole fish, the highest oil yields were from the 70-min extractions with Neutrase and Protamex. Protamex extraction with 35 min resulted in the best fatty acid composition with the highest content of eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) but also increased oxidation compared to treatment with other enzymes. For by-products, the highest oil yield was obtained from the 70-min extraction with Protamex without significant differences in EPA and DHA contents among the oils extracted with different enzymes. Oxidation was lowest in the oil produced with 35-min treatment using Neutrase and Protamex. This study showed the potential of using proteolytic enzymes in the extraction of crude oil from Baltic herring and its by-products. However, further research is needed to optimize enzymatic processing of Baltic herring and its by-products to improve yield and quality of crude oil.

Polyamines play an important role in the maintenance of intestinal permeability. Therefore we aimed to determine the effects of probiotics and omega 3 fatty acids on serum polyamine levels in colitis. Fifty BALB/c mice were randomly grouped as normal, colitis with no treatment applied, colitis treated by probiotics (VSL#3), colitis treated by omega-3, and colitis treated by both probiotics and omega-3. Experimental colitis was induced by injection of 200 mg/kg 2,4-Dinitrobenzenesulfonic acid (DNBS). The probiotic and the omega-3 fatty acid supplements were applied daily by oral gavage. Serum polyamine levels were measured with high performance liquid chromatography (HPLC). In each group, the levels of serum polyamines are the highest in spermidine and the least in spermine. Bowel inflammation in experimentally induced colitis mice resulted in lower serum polyamine concentrations. In probiotic and omega 3 fatty acid supplemented group significant decreases were observed for spermine and spermidine (p<0.001), while no significant changes were obtained for putrescine. Combined supplementation of probiotics and omega-3 fatty acids for 10 days in colitis mice significantly decreased the serum levels of spermine and spermidine.

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.

Abstract Background: The sum of eicosapentaenoic acid (EPA, 20:5 ω3) and docosahexaenoic acid (DHA, 22:6 ω3) in erythrocyte membranes, termed the omega-3 index, can indicate suboptimal intake of omega-3 fatty acids, a risk factor for cardiovascular disease (CVD). To study the effects of fatty acid supplementation, we investigated the rate of incorporation and clearance of these fatty acids in erythrocyte membranes and plasma after intake of supplements. Methods: Twenty study participants received supplementation with either fish oil (1296 mg EPA + 864 mg DHA/day) or flaxseed oil (3510 mg alpha-linolenic acid + 900 mg linoleic acid/day) for 8 weeks. We obtained erythrocyte membrane and plasma samples at weeks 0, 4, 8, 10, 12, 14, 16, and 24 and extracted and analyzed fatty acids by gas chromatography. Results: After 8 weeks of fish oil supplementation, erythrocyte membrane EPA and DHA increased 300% (P &lt;0.001) and 42% (P &lt;0.001), respectively. The mean erythrocyte omega-3 index reached a near optimal value of 7.8%, and remained relatively high until week 12. EPA and DHA showed greater increases and more rapid washout period decreases in plasma phospholipids than in erythrocyte membranes. Flaxseed oil supplementation increased erythrocyte membrane EPA to 133% (P &lt;0.05) and docosapentaenoic acid (DPA, 22:5 ω3) to 120% (P &lt;0.01) of baseline, but DHA was unchanged. In plasma phospholipids, EPA, DPA, and DHA showed a slight but statistically insignificant increase. Conclusions: Erythrocyte membrane EPA+DHA increases during relatively short intervals in response to supplementation at rates related to amount of supplementation. These results may be useful to establish appropriate dosage for omega-3 fatty acid supplementation.

Omega-3 fatty acid is the essential fatty acid and important for human health. Omega-3 fatty acid is also really neededby pregnant and lactating mothers and also children to prevent the malnutrition. Omega-3 fatty acid is also reallyneeded by pregnant and lactating mothers, and children to prevent the malnutrition. The omega-3 fatty acid is commonlyfound in some fish like salmon, tuna, hering, and mackarel. However, those fish are expensive, so alternativesources relatively cheaper fish. One of fish that is low in price and high in production in Nusa Tenggara Barat is Sunglir(Elagatis bipinnulata ). The purpose of this research was to determine free fatty acids content, type of omega-3 fattyacids, and their compositions in head fish oil. Head of sunglir fish was used as a sample because the head was usuallynot consumed. Sunglir fish was obtained from the Ampenan beach (NTB) with a size of 20–30 cm. The extraction methodused in this study was soxhletation with n-hexane solvent and analyzed with Gas Chromatografi (GC), acid ethyl estersfrom the esterification enzymatic of fish oil. Result revealed that the fish oil contained 84% free fatty acid and 0.85%linolenic acid (ALA), 2.80% eicosatrienoic acid (ETA), 0.73% eicosapentaenoic acid (EPA) and 2.41% docosahexaenoicacid (DHA). Saponification and iodine number of head fish oil is 248.24 mg KOH/g oil and 227.16 g Iod/100 g oil.

ABSTRACT Free fatty acids hold important immune-modulatory roles during infection. However, the host’s long-chain polyunsaturated fatty acids, not commonly found in the membranes of bacterial pathogens, also have significant broad-spectrum antibacterial potential. Of these, the omega-6 fatty acid arachidonic acid (AA) and the omega-3 fatty acid decosahexaenoic acid (DHA) are highly abundant; hence, we investigated their effects on the multidrug-resistant human pathogen Acinetobacter baumannii. Our analyses reveal that AA and DHA incorporate into the A. baumannii bacterial membrane and impact bacterial fitness and membrane integrity, with DHA having a more pronounced effect. Through transcriptional profiling and mutant analyses, we show that the A. baumannii β-oxidation pathway plays a protective role against AA and DHA, by limiting their incorporation into the phospholipids of the bacterial membrane. Furthermore, our study identified a second bacterial membrane protection system mediated by the AdeIJK efflux system, which modulates the lipid content of the membrane via direct efflux of lipids other than AA and DHA, thereby providing a novel function for this major efflux system in A. baumannii. This is the first study to examine the antimicrobial effects of host fatty acids on A. baumannii and highlights the potential of AA and DHA to protect against A. baumannii infections. IMPORTANCE A shift in the Western diet since the industrial revolution has resulted in a dramatic increase in the consumption of omega-6 fatty acids, with a concurrent decrease in the consumption of omega-3 fatty acids. This decrease in omega-3 fatty acid consumption has been associated with significant disease burden, including increased susceptibility to infectious diseases. Here we provide evidence that DHA, an omega-3 fatty acid, has superior antimicrobial effects upon the highly drug-resistant pathogen Acinetobacter baumannii, thereby providing insights into one of the potential health benefits of omega-3 fatty acids. The identification and characterization of two novel bacterial membrane protective mechanisms against host fatty acids provide important insights into A. baumannii adaptation during disease. Furthermore, we describe a novel role for the major multidrug efflux system AdeIJK in A. baumannii membrane maintenance and lipid transport. This core function, beyond drug efflux, increases the appeal of AdeIJK as a therapeutic target.
