Effect of flavonoids on circulating levels of TNF-(alfa ) and IL-6 in humans: A systematic review and meta-analysis
No full textEpidemiological or in vitro evidence suggests a potential role for flavonoids as anti-inflammatory agents; we investigated the effect of flavonoids-rich foods or supplements on tumor necrosis factor- alpha (TNF-alfa) and interleukin-6 (IL-6) in long-term placebo-controlled human interven- tion trials. From 110 human intervention studies selected (MEDLINE, EMBASE, CHORANE, and FSTA databases), 32 long-term placebo-controlled trials were suitable for meta-analysis. After sensitivity analysis, seven studies imputed of bias were excluded and 25 studies were analyzed (TNF-a, n = 2404; IL-6, n = 2174). Levels of TNF-a decreased after flavonoid con- sumption in the fixed model only (mean difference (MD) (95% CI): −0.098 (−0.188, –0.009), p = 0.032), but metaregression results showed that neither higher dose, nor a longer duration of intervention were associated with a greater effect size. Subgroup analysis did not reveal any significant effect for quercetin and soy, but other sources (red wine, pomegranate, and tea extracts) showed a significant effect size both in fixed (MD (95% CI): TNF-alfa−0.449 (−0.619, –0.280), p < 0.001; IL-6 −0.346 (−0.612, –0.079), p = 0.011) and random (MD (95% CI): TNF-alfa−0.783 (−1.476, –0.090), p = 0.027; IL-6, −0.556 (−1.062, –0.050), p = 0.031) effect models. High-quality placebo-controlled trials are needed in order to identify flavonoids as the active ingredients
Is nut consumption related to a sustainable diet? A pilot study on italian male consumers
Full text link(1) Background: In recent years, the EAT-Lancet Commission has suggested the inclusion of nuts among proteins from vegetable sources, but this inclusion would imply a higher consumption of nuts compared with a healthy Mediterranean diet. (2) Objective: In this work, we sought to provide a comparison between the macronutrient intakes and environmental impacts of two different types of diet: a diet including nuts and a diet without nuts. (3) Methods: In this pilot study, we recruited 89 Italians divided into two groups: nut consumers (44 individuals) and non-consumers (45 individuals). Food consumption was monitored by a seven-day diary, while the Mediterranean diet scores, habitual physical activity scores, and orthorexia nervosa scores were evaluated through standardized questionnaires. (4) Results: We found that nut consumers had higher physical activity and energy intake levels. High consumption of fat (p < 0.001) and protein (p < 0.001) was observed among nut consumers compared with the levels observed among non-consumers. Moreover, a higher environmental impact of total dietary intake was observed among nut consumers, in terms of carbon (p < 0.05) and land (p < 0.05) footprints; impacts on the water footprint was almost significant (p = 0.06). (5) Conclusions: We suggest that, among plant food proteins, the consumption of complementary proteins from legumes and cereals should be preferred to the consumption of proteins from nuts
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Mediterranean diet for the prevention of gestational diabetes in the covid-19 era: Implications of ll-6 in diabesity
No full textThe aim of this review is to highlight the influence of the Mediterranean Diet (MedDiet) on Gestational Diabetes Mellitus (GDM) and Gestational Weight Gain (GWG) during the COVID- 19 pandemic era and the specific role of interleukin (IL)-6 in diabesity. It is known that diabetes, high body mass index, high glycated hemoglobin and raised serum IL-6 levels are predictive of poor outcomes in coronavirus disease 2019 (COVID-19). The immunopathological mechanisms of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection include rising levels of several cytokines and in particular IL-6. The latter is associated with hyperglycemia and insulin resistance and could be useful for predicting the development of GDM. Rich in omega-3 polyunsaturated fatty acids, vitamins, and minerals, MedDiet improves the immune system and could modulate IL-6, C reactive protein and Nuclear Factor (NF)-κB. Moreover, polyphenols could modulate microbiota composition, inhibit the NF-κB pathway, lower IL-6, and upregulate antioxidant enzymes. Finally, adhering to the MedDiet prior to and during pregnancy could have a protective effect, reducing GWG and the risk of GDM, as well as improving the immune response to viral infections such as COVID-19

No full textChocolate consumers and lymphocyte-to-monocyte ratio: a working hypothesis from a preliminary report of a pilot study in celiac subjects
Full text linkBackground and aim: The aim of this work was to evaluate the relationship between platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR) with habitual consumption of dark chocolate in a group of celiac subjects in which chocolate consumption and lower neutrophil-to-lymphocyte ratio (NLR) association had already been observed. Additionally, due to the known anti-nutrient effect on iron absorption, we evaluated red blood cell count (RBC), mean corpuscular volume (MCV) and hemoglobin (Hb) values. Methods: Chocolate consumers and non-consumers were matched for sex, menopausal status, NLR values over the previously suggested cut off (2.32) for celiac patients, and co-morbidities. Results: Chocolate consumers had high LMR compared to non-consumers, whereas no differences were observed between chocolate consumers and non-consumers in RBC, MCV, Hb and PLR. However, similar number of subjects had PLR higher than the previously suggested cut off (143.7) for celiac disease. Conclusions: This preliminary report suggests a working hypothesis for larger studies aimed at establishing cut off values for LMR in celiac patients and the modulation of this marker by dietary antioxidants
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
