RESUMEN

We previously reported preliminary characterization of adipose tissue (AT) dysfunction through the adiponectin/leptin ratio (ALR) and fasting/postprandial (F/P) gene expression in subcutaneous (SQ) adipose tissue (AT) biopsies obtained from participants in the GEMM study, a precision medicine research project. Here we present integrative data replication of previous findings from an increased number of GEMM symptom-free (SF) adults (N = 124) to improve characterization of early biomarkers for cardiovascular (CV)/immunometabolic risk in SF adults with AT dysfunction. We achieved this goal by taking advantage of the rich set of GEMM F/P 5 h time course data and three tissue samples collected at the same time and frequency on each adult participant (F/P blood, biopsies of SQAT and skeletal muscle (SKM)). We classified them with the presence/absence of AT dysfunction: low (<1) or high (>1) ALR. We also examined the presence of metabolically healthy (MH)/unhealthy (MUH) individuals through low-grade chronic subclinical inflammation (high sensitivity C-reactive protein (hsCRP)), whole body insulin sensitivity (Matsuda Index) and Metabolic Syndrome criteria in people with/without AT dysfunction. Molecular data directly measured from three tissues in a subset of participants allowed fine-scale multi-OMIC profiling of individual postprandial responses (RNA-seq in SKM and SQAT, miRNA from plasma exosomes and shotgun lipidomics in blood). Dynamic postprandial immunometabolic molecular endophenotypes were obtained to move towards a personalized, patient-defined medicine. This study offers an example of integrative translational research, which applies bench-to-bedside research to clinical medicine. Our F/P study design has the potential to characterize CV/immunometabolic early risk detection in support of precision medicine and discovery in SF individuals.

RESUMEN

OBJECTIVE: to evaluate the parameters of inflammatory reaction and oxidative stress in patients with non-alcoholicfatty liver disease (NAFLD) in the remote period after the influence of the Chornobyl accident factors. MATERIALS AND METHODS: Eighty two patients with NAFLD who had been exposed to ionizing radiation as a result ofthe Chornobyl accident and have concomitant cardiovascular pathology were examined. Hematological parametersand the level of highly sensitive C-reactive protein (hsCRP) were determined, and the content of products of oxida-tive modification of lipids and proteins was evaluated. RESULTS: Activation of the processes of oxidative modification of lipids and proteins was observed in most patientswith NAFLD. According to the level of hsCRP, the presence of subclinical inflammation and the risk of developingcomplicated cardiovascular pathology was found in 58 % of patients with NAFLD. The neutrophil / lymphocyte ratiocorrelates positively with hsCRP and can be used as an available routine clinical marker for selection among patientswith NAFLD persons with increased risk of cardiovascular complications. CONCLUSIONS: HsCRP, oxidative modification products of lipids and proteins, ESR, and leukograms should be used toassess the degree of systemic inflammation in people affected by the Chornobyl accident, suffering NAFLD with con-comitant cardiovascular disease.

RESUMEN

PURPOSE: Flavonoid consumption during adolescence could contribute to preventing adult onset of type 2 diabetes mellitus. We investigated the prospective association between habitual intake of flavonoids from fruit and vegetables (FlavFV) during adolescence and risk markers of type 2 diabetes in early adulthood. METHODS: This analysis included participants of the DONALD Study, who had provided a fasting blood sample in adulthood (18-39 years), data on FlavFV-intake during adolescence (females: 9-15 years, males: 10-16 years) and relevant covariates. Habitual FlavFV-intake was either estimated using repeated 3-day weighed dietary records (n = 268), or the validated biomarker hippuric acid (uHA)-excretion in repeated 24-h urine samples (n = 241). Multivariable linear regressions were performed to analyse the prospective associations of FlavFV or uHA with homeostasis model assessment insulin sensitivity (HOMA2-%S), hepatic steatosis index (HSI), fatty liver index (FLI) and a pro-inflammatory score. RESULTS: Higher FlavFV-intake was independently related to higher HOMA2-%S among females (Ptrend = 0.03), but not among males. Both FlavFV-intake and uHA-excretion were inversely associated with HSI (Ptrend < 0.0001 and Ptrend = 0.02, respectively) and the pro-inflammatory score (Ptrend = 0.02 and Ptrend = 0.008, respectively), but not with FLI. CONCLUSIONS: Our data indicate that flavonoid consumption from fruit and vegetables during adolescence is associated with a favourable risk factor profile for type 2 diabetes in early adulthood.

RESUMEN

This literature review of recent clinical and experimental studies describes the role of oxidative stress in the multifactorial and interdisciplinary pathogenesis of non-inflammatory chronic pelvic pain syndrome IIIB (CPPS-IIIB) in men. The authors outline general biological nature of oxidative stress and its mechanisms. More detailed information is presented on cytokine-mediated chronic subclinical inflammation, one of the key mechanisms of oxidative stress, which is currently being actively studied. It is shown that the imbalance between pro- and anti-inflammatory cytokines observed in patients with CPPS-IIIB can explain some features of the clinical course (in particular, the characteristics of the pain syndrome) and the progression of this disease. In this regard, cytokine profiling of prostatic secretion can provide valuable diagnostic, prognostic and monitoring information in the management of this category of patients. Recently published evidence has demonstrated the essential role of the cytokine-mediated chronic inflammatory response as a mechanism of oxidative stress in the pathogenesis of CPPS-IIIB. Further studies in this area are warranted and in the long term may become a basis for the development of new effective pathogenetic pharmacotherapy of CPPS-IIIB.
