How are LGBTQ+ issues represented within labor organizing and how are they linked to broader debates about inequality? We answered these questions by examining press releases, internal resolutions, and online resources from the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) and the Pride at Work (PAW) constituency group. We find that they significantly differ in their approaches to symbolic and substantive representation and agenda setting. Across all three outcomes, PAW and the AFL-CIO vary in LGBTQ+ issue representation. The AFL-CIO engages in more symbolic representation but also devotes resources to collective action that can improve the lives of LGBTQ+ people. PAW places greater emphasis on the interconnectedness of LGBTQ+ and labor issues to mobilize LGBTQ+ people. Our findings highlight the marginal position of LGBTQ+ labor activism in the labor and LGBTQ+ movements, and they demonstrate the challenges associated with linking LGBTQ+ issues to broader debates about inequality in American politics.

The aim of this study is to investigate whether 25-hydroxyvitamin D (25(OH)D) is associated with periodontitis and tooth loss in older adults. A total of 2346 adults underwent a detailed dental examination as part of the health assessment of a national population study – The Irish Longitudinal Study of Ageing. 25(OH)D analysis was performed on frozen non-fasting total plasma using LC-MS. The analysis included both multiple logistic regression and multinominal logistic regression to investigate associations between 25(OH)D concentration, periodontitis and tooth loss, adjusting for a range of potential confounders. Results of the analysis found the mean age of participants was 65·3 years (sd 8·2) and 55·3 % of the group were female. Based on the quintile of 25(OH)D concentration, participants in the lowest v. highest quintile had an OR of 1·57 (95 % CI 1·16, 2·13; P < 0·01) of having periodontitis in the fully adjusted model. For tooth loss, participants in the lowest v. highest quintile of 25(OH)D had a RRR of 1·55 (95 % CI 1·12, 2·13; P < 0·01) to have 1–19 teeth and a RRR of 1·96 (95 % CI 1·20, 3·21; P < 0·01) to be edentulous, relative to those with ≥ 20 teeth in the fully adjusted models. These findings demonstrate that in this cross-sectional study of older men and women from Ireland, 25(OH)D concentration was associated with both periodontitis and tooth loss, independent of other risk factors.

Sour foods, such as citrus fruits, some berries and fermented foods provide a range of nutrients and benefits important to mental health [1]. When sourness is perceived as unpleasant, intake of these foods may be reduced affecting mental health. Early research has shown changes to sour taste perception in depression and stress however, changes in anxiety have not been studied [4-8]. To address this gap and build on the knowledge base, a survey was conducted in which participants (n = 424) rated recalled intensity and liking of sour index foods and completed the Depression, Anxiety, and Stress Scale (DASS-21) to measure these states. Variations in sour taste and mood have been demonstrated between females and males, hence the data were explored for sex-differences. Standard least squares regression (post hoc Tukey’s HSD) compared means between groups, and nominal logistic regression assessed differences in distributions between categories. Recalled sour intensity was 16-19.2% higher in those with scores indicative of mild depression than in those with normal scores in the total sample (p range 0.03-0.04), and 17.9-21.3% higher in females (p values were 0.03). There were no differences in sour taste intensity between the intergroup means for anxiety or stress and no associations between sour liking and any of the mood states. The results suggest that the sourness of index foods increases in depression. Further research to elucidate the biological processes and possible taste-related genetic influences that may be occurring would be beneficial. With this knowledge it may be possible to screen for mood conditions by measuring changes to sour taste that appear alongside other signs and symptoms, create more tailored dietary interventions and develop additional therapeutics.
