Abstract Background Maternal diabetes either pregestational or gestational is the main risk factor contributing in development of diabetic fetopathy (DF) in newborns. There are no generalized signs of DF up to late gestational age due to insufficient sensitivity of the currently employed instrumental methods for diagnosis. Methods This is a cross-sectional prospective controlled study. Here, we reported proteomic investigation for several cases of severe types of diabetic fetopathy (cardiomyopathy (CRDM, n = 37), central nervous system depression (CNSD, n = 35) and hepatomegaly (HPMG, n = 35)) diagnosed during 30–35 gestational weeks and confirmed upon delivery by from patients with type 2 diabetes mellitus (T2DM). Control groups were comprised from women in whom T2DM had been ruled out (n = 40) and group of pregnancies with T2DM who delivered healthy newborns (n = 40). Results We found a composition of serum-based non-trivial markers capable that are strongly associated with the certain type of fetopathy or anatomical malfunctions in the affected newborns. Significant impact on mRNA splicing and DNA reparation has been determined by emerging alterations in CDCL5. Patients of CNSD groups were characterized by utmost depletion (ca. 7% of baseline) of DFP3 neurotrophic factor needed for the proper specialization of cardiomyocytes and oligodendrocytes. Corrupted regulation of non-canonical Wnt-signaling guided by PEDF (in CNSD and HPMG groups) and DAAM2 (in CRDM and HPMG groups) was also proposed. In addition, deficiency in retinoic acid and thyroxine transport was revealed by dramatic increase of TTHY in CNDS group. Conclusions We examined peripheral blood plasma and determined a small proportion of proteins indicating the pre-existing signs of DF. Most of the examined markers are participants of critical processes at different stages of embryogenesis and regulate various phases of morphogenesis. There are proteins regulating splicing and DNA repair, differentiation of neurons and their switching to the post-mitotic state. Therefore, reconstruction of the molecular interplay between the defined in proteins is decisive to appreciate cryptic violations in fetal development on the background of diabetic conditions

THE PURPOSE OF THE STUDY is to carry out an analysis of the literature evaluating diabetic encephalopathy by determining neuromarkers. MATERIAL AND METHODS. In this article, the authors analyzed the literature on the role of neuromarkers in patients with type 2 diabetes mellitus undergoing program hemodialysis. RESEARCH RESULTS. Among biochemical markers, the determination of the level of neurospecific proteins is actively being investigated. The main part of them is autoantigens, entering the bloodstream, can cause the appearance of autoantibodies, which, when the blood-brain barrier is impaired, enter the brain from the blood vessel and cause morphological changes, destructive processes in neurons, as well as the development of nonspecific acute-phase reactions like edema or inflammation. Biomarker studies for the diagnosis of various brain lesions have been under way for more than 20 years, but at present no ideal biomarker has been found. Among biochemical markers, the determination of the level of neurospecific proteins is being actively studied. In patients with type 2 diabetes mellitus undergoing hemodialysis, this issue is also relevant in view of the frequent vascular cerebrovascular complications, but few studies have been conducted. CONCLUSIONS. All of the above emphasizes the need to identify the features of clinical and functional changes in the nervous system in patients with type 2 diabetes mellitus receiving program hemodialysis and to evaluate the prognostic value of neuromarkers in early detection of the degree of brain damage.

The Central Nervous System

One of the most sexually dimorphic aspects of metabolic regulation is the bidirectional modulation of glucose and energy homeostasis by testosterone in males and females. Testosterone deficiency predisposes men to metabolic dysfunction, with excess adiposity, insulin resistance, and type 2 diabetes, whereas androgen excess predisposes women to insulin resistance, adiposity, and type 2 diabetes. This review discusses how testosterone acts in the central nervous system, and especially the hypothalamus, to promote metabolic homeostasis or dysfunction in a sexually dimorphic manner. We compare the organizational actions of testosterone, which program the hypothalamic control of metabolic homeostasis during development, and the activational actions of testosterone, which affect metabolic function after puberty. We also discuss how the metabolic effect of testosterone is centrally mediated via the androgen receptor.

The paper presents the results of studying the effect of electrical impulse therapy on the psychoemotional state in 60 patients with moderate type 2 diabetes mellitus with peripheral sensory polyneuropathy. A comparative double-blind, placebo-controlled study of the inclusion of neuro-like dynamic electroneurostimulation in the rehabilitation course was carried out. By the end of the rehabilitation course in patients of the experimental group, a decrease in the initially high indicator of situational (reactive) anxiety according to the the Spielberger — Khanin State Trait Anxiety Inventory (STAI) by 1,6 times (p = 0,014) and an improvement in the functional state of the central nervous system according to the WAM test were recorded.

Brain Iron Deposition

Background. The underlying brain structural changes in type 2 diabetes mellitus (T2DM) patients have attracted increasing attention. The insulin-resistant state causes iron overload in neurons and leads to lesions in the central nervous system. Quantitative susceptibility mapping (QSM) can provide a noninvasive quantitative analysis of brain iron deposition. We aimed to compare the difference of brain iron deposition in the gray matter nucleus between T2DM patients and healthy elderly individuals using QSM. Methods. Thirty-two T2DM patients and thirty-two age- and gender-matched healthy controls (HCs) were enrolled in this research. Twenty-three patients and twenty-six HCs underwent cognitive assessments. Brain QSM maps were computed from multiecho GRE data using morphology-enabled dipole inversion with automatic uniform cerebrospinal fluid zero reference algorithm (MEDI+0). ITK-SNAP was used to measure the susceptibility values reflecting the content of iron in the regions of interest (ROIs). Results. The study included thirty-two T2DM patients (20 males and 12 females; mean age of 61.09±9.99 years) and 32 HCs (14 males and 18 females; mean age of 59.09±9.77 years). These participants had no significant difference in age or gender (P>0.05). Twenty-three patients with T2DM (11 males and 12 females; mean age, 64.65±8.44 years) and twenty-six HCs (14 males and 12 females; mean age, 62.30±6.13 years) received an assessment of cognitive function. T2DM patients exhibited an obviously (t=3.237, P=0.003) lower Montreal Cognitive Assessment (MoCA) score (26.78±2.35; HCs, 28.42±0.64; normal standard ≥26) and a higher Stroop color-word test (SCWT)-C score [87(65,110); HC, 63(60,76.75), Z=−2.232, P=0.003] than HCs. The mean susceptibility values in the putamen appeared obviously higher in T2DM patients than in HCs (t=−3.994, P<0.001). The susceptibility values and cognitive assessment scores showed no obvious association (P>0.05). However, an obvious correlation was observed between the changes in the susceptibility values in the putamen and the thalamus/dentate nucleus (r=0.404, P<0.001; r=0.423, P<0.001). Conclusion. T2DM patients showed increased susceptibility values in the putamen and had declines in executive functions, but the linear association between them was not statistically significant. Changes in susceptibility values in the putamen indicated increased iron deposition and might be used as a quantitative imaging marker of central nervous system injury in T2DM patients. QSM might be able to help probe micro neuronal damage in gray matter and provide information on diabetic encephalopathy.
