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.

Dietary omega-3 fatty acids (ω3), particularly long-chain ω3 (LCω3), have protective effects against prostate cancer (PCa) in experimental studies. Observational studies are conflicting, possibly because of the biomarker used. This study aimed at evaluating associations between grade reclassification and ω3 levels assessed in prostatic tissue, red blood cells (RBC), and diet. We conducted a validation cross-sectional study nested within a phase II clinical trial. We identified 157 men diagnosed with low-risk PCa who underwent a first active surveillance repeat prostate biopsy session. Fatty acid (FA) intake was assessed using a food frequency questionnaire and their levels measured in prostate tissue and RBC. Associations were evaluated using logistic regression. At first repeat biopsy session, 39 (25%) men had high-grade PCa (grade group ≥2). We found that high LCω3-eicosapentaenoic acid (EPA) level in prostate tissue (odds ratio (OR) 0.25; 95% (confidence interval (CI) 0.08–0.79; p-trend = 0.03) was associated with lower odds of high-grade PCa. Similar results were observed for LCω3 dietary intake (OR 0.30; 95% CI 0.11-0.83; p-trend = 0.02) but no association for RBC. LCω3-EPA levels in the target prostate tissue are inversely associated with high-grade PCa in men with low-risk PCa, supporting that prostate tissue FA, but not RBC FA, is a reliable biomarker of PCa risk.

Omega-3 fatty acids exert a plethora of physiological actions including triglycerides lowering, reduction of inflammatory indices, immunomodulation, anti- thrombotic effects and possibly promotion of exercise performance. Their use is widespread and for commonly ingested doses their side- effects are minimal. We report a case of a 60y amateur athlete who consumed about 20 g omega-3 fatty acids daily from supplements and natural sources for a year. After the intake of cortisone and antibiotics he presented duodenum ulcer and bleeding although he had no previous history of gastrointestinal problems. Although several animal data support gastro-protective effects of omega-3 fatty acids in the present case they were not able to prevent ulcer generation. The present observation may be explained by (i) the high dose of omega-3 fatty acids and their effect on bleeding, (ii) the fact that cortisone increases their oxidation and may render them proinflammatory, (iii) other antithrombotic microconstituents included in the consumed cod-oil and/or the diet of the subject and (iv) the differences in the coagulation and fibrinolytic systems of well- trained subjects. Further studies are needed to substantiate any possible interaction of cortisone and omega-3 fatty acids in wide ranges of intake.
