to determine whether omega-3 fatty acid levels are the potential neurotoxic effects of exposure to particles with diameters of less than 2.5 µm (pm
draft
observation study
participant
In this observation study, a total of 1,315 women (at the age of 65 to 80; average age 70 years at the start of the course) who participated in the Whims-Mri study (Women’s Health Initiative Memory Study-Magnetic Resonance Imaging) were free of dementia between 1996 and 1999. subjected. This cohort was a sub-group of 7,427 people who participated in the clinical studies of the Women’s Health Initiative (WHI-CT) for postmenopausal hormone therapy.
exposure measures
The investigators calculated average PM
The investigators measure the starting values of the Omega-3-Pufa in the red blood cells (RBCS) of the participants and compared them with PM
target parameter
The researchers calculated joint associations of basic lines-omega-3-pufas in red blood cells and pm
important knowledge
After cleaning up for potential confounders, women had significantly larger volumes in white substance and hippocampus in their brains in this cohort who had higher values of RBC LCN3PUFAS. For each interquartile increment (2.02 %) of the Omega-3 index, the average volume was 5.03 cm ( p <0.01) larger in the white substance and 0.08 cm 3 ( p = 0.03) larger in the hippocamp. The associations with erythrocytes, docosahexaenoic acid (DHA) and Eicosapentaenic acid (EPA) mirrors were similar. Higher LCN3PUFA mirrors weaken the inverse associations between PM from
These results indicate that in older women the advantages of omega-3-pufas for brain age can include protection against the adverse effects of air pollution on the volume of the white substance.
clinical implications
In recent years we have observed the constant accumulation of evidence that indicates an exposure to air pollutants, especially the super small fine dust, pn In this report, Chen et al. A simpler way of expressing this is that the consumption of fish seems to protect against the brain damage caused by PM From 2009 to 2016, the fine dust content in the US air fell by about 25 %. According to a working paper of the National Bureau of Economic Research (NBER) from 2019, this trend suddenly shifted in 2016, and PM The omega-3 fatty acids in just 1 to 2 portions of fish per week were enough to achieve a significant benefit. Two implementing regulations in early June 2020 weakened environmental protection. The first regulation temporarily refrained from environmental exams of infrastructure projects in order to promote construction during the economic weakening caused by Covid-19. The second rule changed the methodology used by the EPA for cost-benefit analyzes that result from the Clean Air Act Ordinance, and severely restricted the strength of future air pollution.
In view of these measures and numerous other political changes in recent years, we have to assume that the air quality in our country will continue to deteriorate. To encourage our patients to eat fish regularly - 2 portions per week, as in the study by Chen et al. proposed - is certainly careful, pragmatic and advisable. This will offer our patients a certain “place of control” and give them the feeling that they still have a way to influence their future and health. Nevertheless, as a naturopathic doctor, the sermon great Kausam (which means that the cause finds), this fish meal advertising feels as if we would draw our attention in the wrong direction. We should strive to create a cleaner environment and reduce pollution. The increasing pollution is the problem, not a lack of fish.
