A systematic review and meta-analysis of the Everyday Discrimination Scale and biomarker outcomes.

ABSTRACT: Discrimination has consistently been associated with multiple adverse health outcomes. Like other psychosocial stressors, discrimination is thought to impact health through stress-related physiologic pathways including hypothalamic-pituitary-adrenal (HPA) axis activation, dysregulation of inflammation responses, and accelerated cellular aging. Given growing attention to research examining the biological pathways through which discrimination becomes embodied, this systematic review and meta-analysis synthesizes empirical evidence examining relationships between self-reported discrimination and four biomarker outcomes (i.e., cortisol, C-reactive protein (CRP), interleukin-6 (IL-6), and telomere length) among studies that have used the Everyday Discrimination Scale. We conducted a systematic review of studies discussing self-reported, everyday, or chronic discrimination in the context of health by searching Medline / PubMed (National Library of Medicine, NCBI), PsycInfo (APA, Ebsco) and Web of Science Core Collection (Clarivate). Twenty-five articles met the criteria for meta-analysis, with several reporting on multiple outcomes. Discrimination was associated with elevated CRP levels (r = 0.11; 95% CI: 0.01, 0.20, k = 10), though not cortisol (r = 0.05; 95% CI: -0.06, 0.16, k = 9), IL-6 (r = 0.05; 95% CI: -0.32, 0.42, k = 5), or telomere length (r = 0.03; 95% CI: -0.01, 0.07, k = 6). We identify several points of consideration for future research including addressing heterogeneity in assessment of biomarker outcomes and the need for longitudinal assessments of relationships between discrimination and biomarker outcomes.

Project description:To summarize data on long-term ipsilateral local recurrence (LR) and breast cancer death rate (BCDR) for patients with ductal carcinoma in situ (DCIS) who received different treatments.Systematic review and study-level meta-analysis of prospective (n?=?5) and retrospective (n?=?21) studies of patients with pure DCIS and with median or mean follow-up time of ?10 years. Meta-regression was performed to assess and adjust for effects of potential confounders - the average age of women, period of initial treatment, and of bias - follow-up duration on recurrence- and death-rates in each treatment group. LR and BCDR rates by local treatment used were reported. Outside of randomized trials, remaining studies were likely to have tailored patient treatment according to the clinical situation.Nine thousand four hundred and four DCIS cases in 9391 patients with 10-year follow-up were included. The adjusted meta-regression LR rate for mastectomy was 2.6 % (95 % CI, 0.8-4.5); breast-conserving surgery with radiotherapy (RT), 13.6 % (95 % CI, 9.8-17.4); breast-conserving surgery without RT, 25.5 % (95 % CI, 18.1-32.9); and biopsy-only (residual predominately low-grade DCIS following inadequate excision), 27.8 % (95 % CI, 8.4-47.1). RT?+?tamoxifen (TAM) in conservation surgery (CS) patients resulted in lower LR compared to one or no adjuvant treatments: LR rate for CS?+?RT?+?TAM, 9.7 %; CS?+?RT(no TAM), 14.1 %; CS?+?TAM(no RT), 24.7 %; CS(alone), 25.1 % (linear trend for treatment P?<?0.0001). Compared to CS?+?RT?+?TAM, a significantly higher invasive LR was observed for CS(alone), odds ratio (OR) 2.61 (P?<?0.0001); CS?+?TAM(no RT), OR 2.52 (P?=?0.001); CS?+?RT(no TAM), OR 1.59 (P?=?0.022). BCDR was similar for mastectomy, breast-conserving surgery with or without RT (1.3-2.0 %) and non-significantly higher for biopsy-only (2.7 %). Additionally, the 15-year follow-up was reported where all like-studies had???15-year data sets; the biopsy-only patients had a meta-analysed total LR rate of 40.2 % and the invasive LR rate was 28.1 %. The biopsy-only patients had a???15-year BCDR (that included women with metastatic disease) of 17.9 %; the???15-year BCDR was 55.2 % for those with invasive LR.More local intervention was associated with greater local control for patients with DCIS at long-term follow-up. For patients undergoing breast-conservation, invasive LR was significantly lower when two rather than one adjuvant treatment modalities were given.

Project description:Experiences of discrimination such as everyday racism can negatively affect the mental and physical health of children and adolescents with an immigrant background and impair their integration process in the host societies. Although experiences of racism are part of the everyday life of many minors affected by the process of "Othering" (e.g., those with an immigrant background), an overview of empirical findings is missing for this age group worldwide. A systematic review was conducted to identify and analyze international research on the impact of discrimination on the developmental outcomes and integration of immigrant children and adolescents. Three scientific databases were systematically searched up to June 11, 2021. A total of k = 4,769 identified publications were reviewed based on inclusion and exclusion criteria in terms of the PICOS format by independent reviewers. Thirty-four primary studies published between 1998 and 2021 met all inclusion criteria. The samples examined were mainly migrant youth (k = 30), with only k = 2 studies assessing refugee youth and k = 1 study assessing both migrant and refugee youth. The majority of included studies assessed perceived discrimination, with only k = 1 study directly assessing experiences of racism. The association between discrimination or racism and developmental outcomes was assessed by the included studies within the three main topics of (a) mental and physical health-related outcomes (k = 30, e.g., self-esteem, depressive symptoms), (b) school-related outcomes (k = 6, e.g., academic achievement), and (c) other developmental outcomes (k = 13, e.g., misconduct or delinquency). Data collection procedures were implemented, and findings on minors' developmental outcomes and integration process who experience discrimination and racism were summarized and discussed. The current review suggests experienced (racial) discrimination as a negative predictor of children and adolescents' (mental) health-related outcomes, while no clear results could be found for the association between discrimination and school-related outcomes. A need for more empirical research focusing on the path and (possibly) indirect link between discrimination and children and adolescents' school-related outcomes as well as resulting school recommendations and the chosen career path was derived.Systematic review registration[https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=260291], identifier [CRD42021260291].
