The prevalence of diabetes mellitus is increasing in resource limited settings. Simultaneously, there has been an increase in the number of novel therapies for the management of diabetes mellitus. However, use of novel antidiabetic therapies is limited because of major market access challenges in resource limited settings. Niching products to those patients with the highest absolute risk for major adverse cardiovascular outcomes, and thus most likely to benefit from the therapy, are less likely to have negative budget impact for funders. To improve access, and reduce morbidity and mortality, requires alignment amongst key stakeholders including patient advocacy groups, health care professional councils, national departments of health, the pharmaceutical industry, treasury and finance departments.

Objective(s): The present study aimed to evaluate the receptor of advanced glycation end-products (RAGE), NF-kB, NRF2 gene expression, and RAGE cell distribution in peripheral blood mononuclear cells (PBMC) in subjects with obesity and IR compared with healthy subjects. Materials and Methods: The mRNA expression levels of RAGE, NF-kB, NRF2, and GAPDH were determined in PBMC by qPCR in 20 obese (OB), 17 obese with insulin resistance (OB-IR) subjects, and 20 age and sex-matched healthy subjects (HS). RAGE protein expression and its localization were determined by Western Blot and immunocytochemistry (ICC) analysis, total soluble RAGE (sRAGE) and MCP-1 plasma levels by ELISA. Results: : RAGE, NF-kB, and NRF2 genes mRNA expression in PBMCs did not show variation between groups. RAGE protein was lower in OB and OB-IR groups; RAGE was located predominantly on the cell-surface in the OB-IR group compared to the HS group (22% vs 9.5%, P<0.001). OB-IR group showed lower sRAGE plasma levels, and correlated negatively with HOMA-IR, ALT parameters (r=-0.374, r=-0.429, respectively), and positively with NFE2L2 mRNA (r=0.540) P<0.05. Conclusion: In this study, OB-IR subjects did not reflect significant differences in gene expression; however, correlations detected between sRAGE, biochemical parameters, and NRF2, besides the predominant RAGE distribution on the cell membrane in PBMC could be evidence of the early phase of the inflammatory cascade and the subsequent damage in specific tissues in subjects with OB-IR.

Toxoplasma gondii (T. gondii) is the causal agent of toxoplasmosis. It may produce severe damage in immunocompromised individuals, as well as congenital infection and intrauterine growth restriction (IUGR). Previous reports have associated interleukin IL-33 with miscarriage, fetal damage, and premature delivery due to infections with various microorganisms. However, IL-33 has not been associated with congenital toxoplasmosis. The sST2 receptor has been reported in patients who have had recurrent miscarriages. On the other hand, IL-1β was not found in acute Toxoplasma infection. Our aim was to analyze the associations between the serum levels of IL-33 and IL-1β in IUGR and toxoplasmosis during pregnancy. Eighty-four serum samples from pregnant women who had undergone 26 weeks of gestation were grouped as follows: with anti-Toxoplasma antibodies, without anti-Toxoplasma antibodies, IUGR, and the control group. IgG and IgM anti-T. gondii antibodies, as well as IL-33, ST2, and IL-1β, were determined using an ELISA assay. Statistical analyses were performed using the Pearson and Chi-square correlation coefficients, as well as the risk factors and Odds Ratios (ORs), with a confidence interval of 95% (CI 95). The results showed that 15/84 (17.8%) of cases were positive for IgG anti-Toxoplasma antibodies and 2/84 (2.38%) of cases were positive for IgM. A statistically significant difference was found between IUGR and IL-33 (p < 0.001), as well as between ST2 and IUGR (p < 0.001). In conclusion, IUGR was significantly associated with IL-33 and ST2 positivity based on the overall IUGR grade. No significant association was found between IUGR and the presence of anti-Toxoplasma antibodies. There was no association between IL-1β and IUGR. More research is needed to strengthen the utility of IL-33 and ST2 as biomarkers of IUGR.

The carbohydrate response element binding protein (ChREBP) is a key transcription factor to understand the gene–diet–nutrient relationship that leads to metabolic diseases. We aimed to analyze the association between the rs17145750 and rs3812316 SNVs (single nucleotide variants) of the MLXIPL gene with dietary, anthropometric, and biochemical variables in Mexican Mestizo subjects. This is a cross-sectional study of 587 individuals. Genotyping was performed by allelic discrimination. In addition, liver and adipose tissue biopsies were obtained from a subgroup of 24 subjects to analyze the expression of the MLXIPL gene. An in silico test of the protein stability and allelic imbalance showed that rs17145750 and rs3812316 showed a high rate of joint heritability in a highly conserved area. The G allele of rs3812316 was associated with lower triglyceride levels (OR = −0.070 ± 0.027, p < 0.011, 95% CI = −0.124 to −0.016), the production of an unstable protein (ΔΔG −0.83 kcal/mol), and probably lower tissue mRNA levels. In addition, we found independent factors that also influence triglyceride levels, such as insulin resistance, HDL-c, and dietary protein intake in women. Our data showed that the association of rs3812316 on triglycerides was only observed in patients with an inadequate alpha-linolenic acid intake (1.97 ± 0.03 vs. 2.11 ± 0.01 log mg/dL, p < 0.001).
