Abstract
The aim of this study was to perform a systematic review and meta-analysis on randomized controlled trials investigating the effects of carotenoids on selected inflammatory parameters. PubMed, SCOPUS, and Web of science were searched from inception until April 2021. The random-effect model was used to analyze data and the overall effect size was computed as weighted mean difference (WMD) and corresponding 95% of confidence interval (CI). A total of 26 trials with 35 effect sizes were included in this meta-analysis. The results indicated significant effects of carotenoids on C-reactive protein (CRP) (WMD: ‒0.54 mg/L, 95% CI: ‒0.71, ‒0.37, P < 0.001), and interleukin-6 (IL-6) (WMD: ‒0.54 pg/mL, 95% CI: ‒1.01, ‒0.06, P = 0.025), however the effect on tumor necrosis factor-alpha (TNF-α) was not significant (WMD: ‒0.97 pg/ml, 95% CI: ‒1.98, 0.03, P = 0.0.059). For the individual carotenoids, astaxanthin, (WMD: ‒0.30 mg/L, 95% CI: ‒0.51, ‒0.09, P = 0.005), lutein/zeaxanthin (WMD: ‒0.30 mg/L, 95% CI: ‒0.45, ‒0.15, P < 0.001), and β-cryptoxanthin (WMD: ‒0.35 mg/L, 95% CI: ‒0.54, ‒0.15, P < 0.001) significantly decreased CRP level. Also, only lycopene (WMD: ‒1.08 pg/ml, 95%CI: ‒2.03, ‒0.12, P = 0.027) led to a significant decrease in IL-6. The overall results supported possible protective effects of carotenoids on inflammatory biomarkers.

Abstract
Purpose. To study the effect of 1-year daily consumption of a dairy drink containing lutein-enriched egg yolks on macular pigment optical density (MPOD) and visual function parameters in elderly subjects with ocular drusen and/or retinal pigment abnormalities. Methods. One hundred and one subjects were recruited to participate in this randomized, double-blind, placebo-controlled parallel intervention trial. Statistical analyses were performed with 46 subjects in the lutein group and 43 in the control group. MPOD, best corrected visual acuity (BCVA, logMAR), and dark adaptation were measured at the start of the study, after 6 months and after 12 months. Plasma lutein and zeaxanthin concentrations were assessed at baseline and at the end of the study. Results. In the lutein group, plasma lutein concentrations increased significantly from 205 ng/mL at baseline to 399 ng/mL after twelve months of intervention. MPOD increased significantly from 0.45 to 0.52 and BCVA improved significantly from −0.04 to −0.09 LogMar. Differences in rod dark adaptation rate between both groups were not significant. Conclusion. Daily consumption of a dairy drink containing lutein-enriched egg yolks for one year improves visual acuity, MPOD, and plasma lutein concentration in elderly subjects with drusen and/or retinal pigment epithelial abnormalities.

Abstract
BACKGROUND AND AIMS Earlier studies in our group suggested that traditionally prepared buttermilk influences cholesterol metabolism. We therefore designed a study to evaluate whether traditionally prepared buttermilk lowers serum low-density lipoprotein cholesterol (LDL-C) and/or prevents the LDL-C raising effect of egg yolks. METHODS AND RESULTS Mildly hypercholesterolemic subjects were randomly allocated to one of four diet groups consuming daily at lunch 80 ml skimmed milk with (n = 23) or without (n = 25) lutein-enriched egg yolk (28 g from 1.5 eggs providing 323 mg cholesterol) or traditionally prepared buttermilk with (n = 23) or without (n = 21) lutein-enriched egg yolk during a 12 week period. Fasting blood samples were taken to measure concentrations of serum lipids, (apo)lipoproteins, liver and kidney function markers, and plasma lutein, zeaxanthin and high-sensitive C-reactive protein (hsCRP). Egg yolk consumption significantly increased serum total cholesterol (total-C) (p = 0.035) and LDL-C concentrations (p = 0.022). Buttermilk did not change the effects of egg yolk on serum lipids and (apo)lipoproteins. There was a trend towards significant lower total-C (p = 0.077), but not LDL-C (p = 0.204) concentrations in the buttermilk groups. Plasma lutein and zeaxanthin concentrations increased significantly (p < 0.001) in the egg yolk groups. CONCLUSION In mildly hypercholesterolemic subjects, daily consumption of traditionally prepared buttermilk for 12 weeks did not lower serum total-C or LDL-C concentrations, nor did it prevent the serum total-C and LDL-C raising effect of daily egg yolk consumption. REGISTRATION NUMBER This study is registered at www.clinicaltrials.gov as NCT01566305.

Carotenoids, inflammation, and oxidative stress--implications of cellular signaling pathways and relation to chronic disease prevention. Nutr Res 2014; 34:907-29.

Abstract
Several epidemiologic studies have shown that diets rich in fruits and vegetables reduce the risk of developing several chronic diseases, such as type 2 diabetes, atherosclerosis, and cancer. These diseases are linked with systemic, low-grade chronic inflammation. Although controversy persists on the bioactive ingredients, several secondary plant metabolites have been associated with these beneficial health effects. Carotenoids represent the most abundant lipid-soluble phytochemicals, and in vitro and in vivo studies have suggested that they have antioxidant, antiapoptotic, and anti-inflammatory properties. Recently, many of these properties have been linked to the effect of carotenoids on intracellular signaling cascades, thereby influencing gene expression and protein translation. By blocking the translocation of nuclear factor κB to the nucleus, carotenoids are able to interact with the nuclear factor κB pathway and thus inhibit the downstream production of inflammatory cytokines, such as interleukin-8 or prostaglandin E2. Carotenoids can also block oxidative stress by interacting with the nuclear factor erythroid 2-related factor 2 pathway, enhancing its translocation into the nucleus, and activating phase II enzymes and antioxidants, such as glutathione-S-transferases. In this review, which is organized into in vitro, animal, and human investigations, we summarized current knowledge on carotenoids and metabolites with respect to their ability to modulate inflammatory and oxidative stress pathways and discuss potential dose-health relations. Although many pathways involved in the bioactivity of carotenoids have been revealed, future research should be directed toward dose-response relations of carotenoids, their metabolites, and their effect on transcription factors and metabolism.

Abstract
Increasing evidence suggests a beneficial effect of lutein and zeaxanthin on the progression of age-related macular degeneration. The aim of this study was to investigate the effect of lutein or zeaxanthin enriched eggs or a lutein enriched egg-yolk based buttermilk beverage on serum lutein and zeaxanthin concentrations and macular pigment levels. Naturally enriched eggs were made by increasing the levels of the xanthophylls lutein and zeaxanthin in the feed given to laying hens. One hundred healthy volunteers were recruited and randomized into 5 groups for 90 days. Group one added one normal egg to their daily diet and group two received a lutein enriched egg-yolk based beverage. Group three added one lutein enriched egg and group four one zeaxanthin enriched egg to their diet. Group five was the control group and individuals in this group did not modify their daily diet. Serum lutein and zeaxanthin concentrations and macular pigment densities were obtained at baseline, day 45 and day 90. Macular pigment density was measured by heterochromatic flicker photometry. Serum lutein concentration in the lutein enriched egg and egg yolk-based beverage groups increased significantly (p<0.001, 76% and 77%). A strong increase in the serum zeaxanthin concentration was observed in individuals receiving zeaxanthin enriched eggs (P< 0.001, 430%). No changes were observed in macular pigment density in the various groups tested. The results indicate that daily consumption of lutein or zeaxanthin enriched egg yolks as well as an egg yolk-based beverage show increases in serum lutein and zeaxanthin levels that are comparable with a daily use of 5 mg supplements.

Abstract
OBJETIVO: Avaliar as propriedades físico-químicas, microbiológicas e nutricionais de dietas enterais artesanais padronizadas preparadas nos domicílios de pacientes em terapia nutricional domiciliar. MÉTODOS: Foram desenvolvidas duas formulações de dietas enterais (F1=1,2kcal/mL e F2=1,5kcal/mL), elaboradas com maltodextrina (155/155g), concentrado proteico de soro de leite (30/15g) e óleos vegetais (30/60g) dissolvidos em água (q.s.p.1000mL). Os cuidadores receberam os ingredientes e as medidas padrão e foram orientados quanto ao preparo e às boas práticas de manipulação. O estudo teve duração de quatro meses, e amostras das dietas preparadas nos domicílios de 33 pacientes foram coletadas e analisadas no início e no final deste período. As amostras foram avaliadas quanto à sua adequação percentual em relação aos valores prescritos de macronutrientes e energia, bem como aos padrões microbiológicos estabelecidos pela legislação vigente. RESULTADOS: As dietas formuladas (Formulação 1/Formulação 2) apresentaram os seguintes teores de macronutrientes, energia e osmolalidade: água - 73,5/70,0%; proteína - 4,4/6,0%; lipídeo - 4,3/6,6%; carboidrato - 16,9/16,4%; energia - 120/150kcal/100mL; osmolalidade - 440/450mOsm/kg.H2O. As variações nas adequações percentuais das amostras domiciliares foram menores que 20,0% tanto na primeira quanto na última amostragem. As proporções de amostras em desacordo com os padrões legais foram significantemente menores nas amostras finais, 24,0% e 36,0% para bactérias mesófilas e coliformes, respectivamente. CONCLUSÃO: O preparo das dietas nos domicílios apresentou boa reprodutibilidade; no entanto, a qualidade microbiológica ainda permanece uma questão preocupante, exigindo uma atuação cuidadosa do profissional de saúde nos domicílios.

Abstract
BACKGROUND Anemia is a common and serious complication in patients with inflammatory bowel disease. The present study was dedicated to evaluate the therapeutic efficacy of erythropoietin (EPO) combined with enteral nutrition (EN) in anemic Crohn's disease (CD) patients, in terms of hemoglobin level, treatment success rate, adverse events, and predictor of this therapy. MATERIALS AND METHODS We performed a prospective study in CD patients. On the basis of hemoglobin level, all enrolled patients were divided into anemic and nonanemic groups. The anemic group was further divided into EPO and non-EPO subgroups, depending on whether EPO was prescribed. Hematological and other parameters were measured initially and in the first 4 weeks after starting treatment. RESULTS In total, 109 patients (49 nonanemic and 60 anemic, including 38 EPO and 22 non-EPO) were included. The prevalence of anemia in CD was 55.05%. Age, disease behavior, Crohn's Disease Activity Index scores, C-reactive protein, and erythrocyte sedimentation rate were significantly different between anemic and nonanemic groups. An increase in hemoglobin level and a significant decrease in C-reactive protein level were observed in the EPO treatment group. Treatment success rate was 63.16% in the EPO group, whereas none of patients achieved treatment success in the non-EPO group. CONCLUSION EPO combined with EN can improve the hemoglobin level in anemic CD patients.

Abstract
BACKGROUND It is unclear whether plant stanols lower serum LDL-cholesterol concentrations and cholesterol-standardized fat-soluble antioxidant concentrations dose-dependently when consumption exceeds the recommended daily intakes of 2.0-3.0 g. OBJECTIVE The objective was to study the relation between plant stanols provided as plant stanol esters on changes in serum concentrations of LDL cholesterol and fat-soluble antioxidants. DESIGN Healthy subjects (n = 93) with slightly elevated serum total cholesterol concentrations (5.0-8.0 mmol/L) received, after a 3-wk run-in period, control products (n = 22) or products (margarine and soy-based yogurt) providing 3 g (n = 24), 6 g (n = 22), or 9 g (n = 25) plant stanols provided as fatty acid esters for 4 wk. RESULTS Serum LDL cholesterol decreased dose-dependently. Compared with control, decreases in the 3-g group were 0.32 mmol/L (7.4%; P = 0.005 after adjustment for multiple comparisons). An intake of 6 g plant stanols caused an additional decrease of 0.18 mmol/L (4.5%; P = 0.100 compared with the 3-g group). In the 9-g group, a further decrease of 0.22 mmol/L (5.4%) was observed (P = 0.048 compared with the 6-g group). Serum LDL-cholesterol concentrations were lowered by 17.4% in the 9-g group compared with the control group. No effects on cholesterol-standardized beta-carotene concentrations were observed. Even the change of -0.01 mumol/mmol cholesterol (or -9.2%; P = 0.341) in the 3-g group compared with the control group was not statistically significant because of the large variation in response. Serum HDL-cholesterol and triacylglycerol concentrations, cholesterol-standardized alpha-tocopherol and lutein concentrations, and plasma markers reflecting liver and renal function were not affected. CONCLUSIONS Daily consumption of plant stanols up to 9 g reduces serum LDL-cholesterol concentrations linearly up to 17.4%. For cholesterol-standardized fat-soluble antioxidant concentrations, such a relation could not be ascertained.
