The effect of n-3 polyunsaturated fatty acids-enriched hen eggs consumption on IgG and total plasma protein N-glycosylation in healthy individuals and cardiovascular patients.

This study determined the effect of n-3 polyunsaturated fatty acids (n-3 PUFAs)-enriched hen eggs consumption on immunoglobulin G (IgG) and total plasma protein N-glycan profiles and inflammatory biomarkers level in healthy individuals (N = 33) and cardiovascular (CV) patients (N = 21). Subjects were divided to Control-Healthy and Control-CV subgroups [consumed three regular hens' eggs/daily (249 mg n-3 PUFAs/day)], and n-3 PUFAs-Healthy and n-3 PUFAs-CV subgroups [consumed three n-3 PUFAs-enriched hen eggs/daily (1053 mg n-3 PUFAs/day)] for 3 weeks. Serum-free fatty acids profile and high-sensitivity C-reactive protein, interleukin 6 and 10 (IL-6, IL-10) and tumor necrosis factor alpha were measured. Total plasma protein and IgG N-glycome have been profiled before and after dietary protocols. Serum n-3 PUFAs concentration significantly increased following n-3 PUFAs hen eggs consumption in both n-3 PUFAs-Healthy and n-3 PUFAs-CV. IL-10 significantly increased in both Healthy subgroups, whereas no change occurred in CV subgroups. Derived IgG N-glycan traits: bisecting N-acetylglucosamine (B) significantly decreased in n-3 PUFAs-Healthy, whereas agalactosylation (G0) and core fucosylation (CF) significantly increased in Control-Healthy. Derived total plasma protein N-glycan traits: high branching glycans, trigalactosylation, tetragalactosylation, trisialylation, tetrasialylation and antennary fucosylation significantly decreased, whereas G0, monogalactosylation (G1), neutral glycans (S0), B, CF and oligomannose structures significantly increased in n-3 PUFAs-CV. Digalactosylation significantly decreased, and G0, G1, S0, disialylation, B and CF significantly increased in Control-CV. n-3 PUFAs consumption alters IgG N-glycan traits and IL-10 in healthy individuals, and total plasma protein N-glycan traits in CV patients, by shifting them toward less inflammatory N-glycosylation profile.

Prevalence, habits and personal attitudes towards smoking among health care professionals.

BACKGROUND: Tobacco use is the second major cause of morbidity and the 4th most common health risk factor in the world. Medical professionals have a critical role in the process of smoking cessation both as advisers and behavioural models for the citizens. The aim of this study was to investigate the prevalence of smoking among health care professionals, their smoking habits and personal attitudes toward smoking, role and the responsibility of health care professionals in the prevention of smoking. RESULTS: Out of the total number of examinees, 175 (35,1%) are active smokers, 29 (5,8%) are former smokers, and 295 (59,1%) are non-smokers. Nurses with secondary education disagree the most with the claim that passive smoking is more harmful to health (χ2 test, p = .008), also with the claim that the introduced Smoking Act is fair to smokers (χ2 test, p = .021). More nurses with secondary education disagree completely or partially that one should pay attention to smoking in the presence of non-smokers (χ2 test, p = .012). CONCLUSION: Training programs for health care workers are needed to improve their ability in smoking cessation techniques to provide active support to their patients.
