RETRACTED ARTICLE: Association of cord blood asprosin concentration with atherogenic lipid profile and anthropometric indices

Abstract

Background Elevated lipids in umbilical cord blood affect fetal programming, leading to a higher risk of developing cardiovascular disease in later life. However, the causes of changes in the lipid profile of umbilical cord blood are not clear yet. This study aimed for the first time to determine the association of asprosin concentration with TAG, TC, HDL-C, LDL-C concentrations and TAG/HDL-C, TC/HDL-C, LDL-C/HDL-C and non-HDL-C/HDL-C ratio in umbilical cord blood as well as newborn anthropometric indices. This cross-sectional study was based on 450 mother- newborn pairs of a birth cohort study in Sabzevar, Iran. Multiple linear regression was used to estimate the association of lipid concentration and lipid ratios as well as birth weight (BW), birth length (BL), head circumference (HC) and chest circumference (CC) with asprosin in cord blood samples controlled for the relevant covariates. Result In fully adjusted models, each 1 ng/mL increase in asprosin was associated with 0.19 (95% CI 0.06, 0.31, P < 0.01), 0.19 (95% CI 0.10, 0.29, P < 0.01), 0.17 (95% CI 0.09, 0.25, P < 0.01), 0.17 (95% CI 0.09, 0.25, P < 0.01), 0.01 (95% CI 0.00, 0.013, P < 0.01), 0.01 (95% CI 0.01, 0.01, P < 0.01), 0.01 (95% CI 0.01, 0.01, P < 0.01) and 0.01 (95% CI 0.01, 0.01, P < 0.01) increase in TAG, TC, LDL-C, TAG/HDL-C, TC/HDL-C, LDL-C/HDL-C and non-HDL-C/HDL-C ratio respectively. Moreover, higher asprosin levels was positively associated with newborn BW, BL, HC and CC; however, these associations were not statistically significant. Conclusion Overall, our findings support the positive association between cord asprosin concentration and the development of atherogenic lipid profile in newborns. Further studies are needed to confirm the findings of this study in other populations.

“…The intial step in assisting patients in better controlling their condition is to improve self-care behaviors, which emphasizes the significance of efficient elements for the patient self-treatment. Self-care also enhances the effectiveness of the illness's therapy and declines the likelihood of complications [27][28][29][30][31][32][33][34][35].…”

Reprogramming the tumor microenvironment to improve the efficacy of cancer immunotherapies

“…Tumor cell expressing CD47 binds to SIRPα (signal-regulatory protein α) on macrophages with antitumor activity and thus suppresses phagocytosis [17]. Tumor-associated neutrophils (TANs) express PD-L1 and suppress the antitumor responses mediated by T cells [18]. On other hand, tumor cells interfere with the recruitment of effector cells to the tumor site, impair the antitumor functions of innate immune cells (DCs and NKs cells) or switch their differentiation toward immature or regulatory cells [19,20].…”

“…Rinsing with 0.05 and 0.2% of sodium fluoride mouth rinse can cause an increase in surface microhardness [7]. Enamel microhardness is a measurement used for the evaluation of the effects of different types of minerals and other agents on the enamel surfaces used in dental experiments to measure the microhardness and hardness of teeth [8]. It resembles the microhardness properties of enamel surfaces determined by indentation performed by applying a diamond indenter such as a Vickers or Knoop indenter into the surface of the tested agents under the average of 1 to 1000 gm load measured by a microscope because the indentations are very small [9].…”
