This secondary analysis evaluates pulmonary outcome in 204 extremely preterm infants, randomized to receive AA (100 mg/kg/day) and DHA (50 mg/kg/day) enterally from birth until term age or standard care. Pulmonary morbidity was primarily assessed based on severity of bronchopulmonary dysplasia (BPD). Serum levels of AA and DHA during the first 28 days were analysed in relation to BPD. Supplementation with AA:DHA was not associated with increased BPD severity, adjusted OR 1.48 (95 % CI 0.85–2.61), nor with increased need for respiratory support at post menstrual age 36 weeks or duration of oxygen supplementation. Every 1 % increase in AA was associated with a reduction of BPD severity, adjusted OR 0.73 (95 % CI 0.58–0.92). In conclusion, in this study, with limited statistical power, enteral supplementation with AA:DHA was not associated with an increased risk of pulmonary morbidity, but higher levels of AA were associated with less severe BPD. Whether AA or the combination of AA and DHA have beneficial roles in the immature lung needs further research.</p></div>","PeriodicalId":94179,"journal":{"name":"Prostaglandins, leukotrienes, and essential fatty acids","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0952327824000073/pdfft?md5=22466bfc1cf986149354830dde78863a&pid=1-s2.0-S0952327824000073-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139894153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Other marine fatty acids may also provide health benefits and it is of interest to understand their activity. Long chain mono-unsaturated fatty acids (LCMUFA) have shown biological activity in studies of metabolic health in animal models. Here, we report two intervention studies using a fish oil with a high LCMUFA content where cetoleic acid is the predominant fatty acid (Cetoleic rich oil: CRO). In CetoIndex, a placebo-controlled study in 55 healthy volunteers, the omega-3 index increased similarly to that seen with an oil containing higher levels of omega-3 fatty acids. In Optihud, a placebo-controlled study in 28 female volunteers, the CRO reduced erythema in skin, which is a marker of inflammation. The results of this pilot study support the use of a CRO for increasing the omega-3 index with potential benefits on skin inflammation.</p></div>","PeriodicalId":94179,"journal":{"name":"Prostaglandins, leukotrienes, and essential fatty acids","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0952327824000103/pdfft?md5=f938c0fced15a60048de5c41bd2818a1&pid=1-s2.0-S0952327824000103-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141054298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-eight-day old male and female liver <em>Elovl2</em>-KO and control mice were placed onto one of two dietary protocols for a total of 8 weeks (4–8 mice per genotype, per diet, per sex): 1) an 8-week 2 % ALA in total fat diet or 2) a 4-week 2 % ALA diet followed by a 4-week 2 % ALA + 2 % DHA diet. Following this 8-week feeding period, 12-week-old mice were sacrificed and serum, red blood cells (RBC), liver, heart and brain were collected and fatty acid levels measured.
