Recent crisis and conflicts in African countries, the Middle East and the Americas have led to forced population migration and rekindled concern about food security. This article aims to map in the scientific literature the implications of forced migration on food and nutrition of refugees. Scoping Review, and database search: databases: PubMed Central, LILACS, SciElo, Science Direct and MEDLINE. Languages used in the survey were: English, Portuguese and Spanish, with publication year from 2013 to 2018. 173 articles were obtained and after removing of duplicates and full reading, 26 articles were selected and submitted to critical reading by two reviewers, resulting in 18 articles selected. From the analysis of the resulting articles, the following categories emerged: Food Inequity; Cultural Adaptation and Nutrition; Emerging Diseases and Strategies for the Promotion of Nutritional Health. Food insecurity is a marked consequence of forced international migration, and constitutes an emerging global public health problem, since concomitant with increasing population displacements also widens the range of chronic and nutritional diseases.
Cutaneous melanoma is the most aggressive skin cancer with high mortality. Proinflammatory cytokines can modulate the proliferation and survival of cutaneous melanoma cells. Higher levels of interleukin-1β (IL1B) were associated with tumor cell proliferation, invasion, and migration, and the IL-1 type II receptor (IL1R2) serves as an endogenous inhibitor of IL1B signaling. Single-nucleotide variations (SNVs) in these genes (IL1B rs16944 and IL1R2 rs4141134) can modulate cytokine production and binding; however, their role in cutaneous melanoma is still unknown. Thus, we investigated the influence of the above SNVs in clinicopathological aspects and cutaneous melanoma patients' survival.In the present study, we analyzed 193 patients with cutaneous melanoma for IL1B c.-598T>C (rs16944) and IL1R2 c.-2009G>A (rs4141134) genotypes with TaqMan assays. Differences between groups were calculated using χ 2 or Fisher's exact test and multiple logistic regression. Progression-free survival (PFS) and melanoma-specific survival were calculated by Kaplan-Meier and Cox methods. The prognostic value of IL1R2 was also analyzed by the online consensus survival webserver for skin cutaneous melanoma (OSskcm). We found that IL1R2 rs4141134 GG genotype was more common in patients with nodular subtype (49.1% vs. 29.8%, P = 0.01) and the frequency of IL1R2 rs4141134 GG or GA was higher in patients with Clark levels III-V (87.4% vs. 75.8%, P = 0.04). Patients with IL1R2 rs4141134 GG or GA genotypes presented lower PFS (hazard ratio: 3.12, 95% confidence interval, 1.10-8.79, P = 0.03) when compared with AA genotype, supported by OSskcm results. Thus, our study presented for the first time preliminary evidence that IL1R2 rs4141134 SNV may modulate cutaneous melanoma clinicopathological aspects and survival possible by allowing IL1B signaling.
Background
Abnormalities in the intrinsic apoptosis pathway, associated with single nucleotide variants (SNVs) in caspase (CASP) genes, alter head and neck squamous cell carcinoma (HNSCC) proliferation and progression. This prospective study aimed to evaluate whether CASP9 c.‐1339A>G and CASP3
c.‐1191A>G SNVs influence the outcome of patients with HNSCC. Two hundred sixty‐two HNSCC patients were enrolled in the study.
Methods
DNA and RNA of peripheral blood samples were analyzed using real‐time polymerase chain reaction (PCR) for genotyping and quantitative PCR method for gene expression, respectively. Differences in CASP3 expressions were analyzed using the Mann‐Whitney test. Event‐free survival (EFS) and overall survival (OS) were calculated using the Kaplan‐Meier curves, log‐rank test, and Cox analyses.
Results
CASP3 c.‐1191AG or GG genotype was associated with higher CASP3 expression when compared with AA genotype (0.50 arbitrary units (AUs) ± 0.29 standard deviation (SD) vs 0.28 AUs ± 0.12 SD; P = .02). Patients with CASP9 c.‐1339GG genotype had 1.54 more chance of presenting disease progression or relapse than patients with CASP9 c.‐1339AA or AG genotype. Patients with CASP9 c.‐1339GG and CASP3 c.‐1191GG combined genotype had 2.64 more chance of presenting progression or relapse of the disease and 2.84 more chance of evolving to death than those with the remaining combined genotypes.
Conclusions
Our findings provide, for the first time, preliminary evidence that inherited abnormalities in the intrinsic apoptosis pathway, related to CASP9 c.‐1339A>G and CASP3 c.‐1191A>G SNVs, act as predictors of HNSCC patients' survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
